The present investigation was conducted with the aim of identifying the application of semantic technology in information retrieval in the softwares of digital libraries.

This survey is applied one which is done by descriptive method. Sampling population includes 8 digital library softwares Simorgh, Payam Mashregh, Pars Azarakhsh, Payam Hanan, Rasa, Tebyan, Saman and Pasargad. After reviewing the literature and available resources, the criteria related to semantic technology components were determined in data retrieval in digital library softwares. The tool used for gathering the data is the checklist that is used in the field of semantic technological practices in marketing information in digital library softwares, this is under the observation of experts, in addition, the method of Delphi is used in this investigation in 3 fields namely semantic technological architecture, semantic technological tools, semantic technologies in marketing information and the level of implementation. In order to analyze the data, Excel and SPSS 25 softwares were used.

The findings showed that digital libraries do not have a suitable condition and they need the layers more than the first designing. Also, semantic tools and implemented languages have a very weak semantic technology, and there are not many semantic tools for development and implementation, and they surpassed each other in a few cases. Furthermore, in terms of implementing tools, they do not have a suitable situation and by paying attention to this area in information marketing, it needs a serious observing by the digital library software designers. But, in semantic technology in information marketing activities the situation was suitable, however, the layers of its implementing in digital libraries is not in a suitable condition. This research, in addition to providing a checklist on the application of semantic technology in data retrieval in digital library software, based on existing records and expert opinion, has made it possible for designers and programmers of digital library software to identify their strengths and weaknesses, with the criteria and components in this area, and the degree of importance of each of them, will become more familiar with the design of digital library softwares.

In modern society, information literacy is considered as an essential element for the creativity of employees in the organizations. Therefore, having creative and literate employees is one of the necessities of any organization. The purpose of this study is to investigate the relationship between information literacy and creativity of employees of the Management and Planning Organization of East Azerbaijan Province.

This research is applied research that has been done by survey method and descriptively. The statistical population includes the employees of the Management and Planning Organization of East Azerbaijan Province in 1400. Using Morgan table of statistical sample size, out of 128 employees, 97 people were selected by simple random sampling and tested. Data collection tool is a Standard questionnaire. Validity was confirmed by a number of professors and its reliability was confirmed by Cronbach's alpha of 93%. Data were analyzed by SPSS software using analysis of variance, independent t-test and regression.

The findings showed that the correlation coefficient between information literacy and employee creativity is 0.496. In addition, among the 4 components of information literacy, identifying information needs with a coefficient of 0.510 has a greater impact on employee creativity, so information literacy and creativity of employees of the Management and Planning Organization of East Azerbaijan Province is above average and in good condition.

According to the research results, it is a creative and innovative organization whose employees have up-to-date knowledge and information literacy. Therefore, hiring and retaining employees with information literacy, creative and innovative, should be at the top of other organizational affairs.

This survey is done in order to identify the Simorg software surface external architecture information from the points of view of expertised librarians' Management and planning Organization in Iran.

According to the objectives, nature of the subject, statistical population, temporal and spatial conditions, the present research method is descriptive and inferential. An applied research that aims to develop practical knowledge in a particular field. The population of the Management and Planning Organization research librarians all 60 provinces that were considered. Research data were also collected using a researcher-made questionnaire. After developing the questionnaire, in order to ensure the validity of the questionnaire to 10 experts in the field of information architecture had significant activities, send questions and comments on the final shape was used. besides, its stability was confirmed 93 percent by Cronbach's alpha. In addition to using descriptive statistical analysis of parameters such as frequency, median, mean and standard deviation, analysis of variance and t tests, especially inferential statistics were used. Kolmogorov-Smirnov test was also performed to check the compliance of data with normal distribution.

the results indicated that the librarians surveyed in this study, with an average of 55/3, the outer surface of the information architecture of Phoenix software in terms of organization, position on the screen, forms have data entry, alerts and The error is in good condition. Findings showed that between the views of librarians in this study with an average of 73.3, the degree of interaction with the external level of Simorgh software in terms of capabilities and features of information architecture such as processing speed and software interaction, the ability to correct user errors, data exchange, Routing, use of Boolean operators, etc. are in good condition. Findings showed that among the librarians in this study with an average of 52.3, Simorgh software has flexibility and user-friendliness and also has a significant effect on increasing the effectiveness, efficiency and job satisfaction of librarians.

Information architecture is a way to organize content in software systems with the aim of increasing the accessibility and comprehensibility of information by users. The role of information architecture as a tool for planning, organizing and application development of information technology is very prominent. Therefore there is so much coincidence between Simorg software external surface architecture information from Plan and Budget Organizatin in librarians' points of view in the provinces of country.

The purpose of this study was to compare the existing and desirable use of semantic technology in data retrieval in digital library software of Iran.

This is an applied research. Due to the specific nature of the research, the combination of Delphi methods, analytical scrutiny were used. After examining the literature and available resources, criteria related to semantic technology components were determined in data retrieval in digital library software. Because of the limitations regarding the lack of appropriate criteria and the need for validation in many cases, it was necessary to use a suitable method for this. Finally, the Delphi method was selected. Using the Delphi panel, the coefficients of the general criteria and semantic technology components were determined in the data retrieval of digital libraries. The statistical population of the study was consisting of eight software of the Simorgh digital library, Mashreq, Pars Azarakhsh, payam Hanan, Rasa, Tebiyan, Saman and Pasargad. The data processing tool is a checking log . According to experts, Delphi's methodology was used in 3 parts of semantic technology architecture, semantic technology tools, semantic technology in data retrieval and their implementation levels this is under the observation of experts, in addition, the method of Delphi is used in this investigation in 3 fields which are meaningful technological architecture, Data were analyzed using structural equation analysis of variance-axis, partial least squares modeling (PLS -SEM), Kolmogorov-Smirnov and Kruskal-Wallis tests and Spss25 softwares was used..

There is a significant difference between the current status of the software companies of digital libraries in terms of architectural structure, semantic tools and semantic technology in retrieving information with the desired status of the research. The findings of the investigation showed that digital libraries in terms of meaningful technological practical and meaningful technological architecture in information marketing do not have a suitable condition and they need the layers more than the first designing. Also, semantic tools and implemented languages have a very weak semantic technology, and there are not many semantic tools for development and implementation, And they surpassed each other in a few cases. the majority at the initial stage were knowing. Furthermore implementing tools, it does not have a suitable situation and by paying attention to this area in. Therefore, given the importance of semantic technologies in information retrieval, there is a need for serious rethinking and efforts to achieve the desired status of digital library software designers in Iran.

The aim of this study was to identify semantic technologies and their importance in information retrieval in Iranian digital library software.

This applied study was descriptively performed via survey method. This paper firstly identified the components of semantic technology through documentary (libraries) method and secondly prepared a checklist on the application of semantic technology in information retrieval in digital library software based on expertschr('39') opinions and Delphi method in three sections of semantic technology architecture, semantic technology tools and semantic technology in information retrieval. Excel and SPSS 25 were used to analyze the data.

The findings have shown that the semantic technology architecture structure with an average of 43%, semantic technology tools with 59% and semantic technology with 41% are very important in digital libraries. Using semantic technologies, digital library users will be able to access the information resources they need more quickly.

As digital libraries are in the early stages of development and this is especially true in developing countries; therefore, this study has provided the checklist in the field of application of semantic technology in information retrieval in digital library software based on existing backgrounds and expertschr('39') opinions. Moreover, the current study has enabled the designers and software developers of digital library software to identify their strengths and weaknesses as well as more familiar with the criteria and components in this field and the importance of each for enjoying them in designing digital library software.

Dramatic increase in antibiotic-resistant bacteria highlights the need for new compounds with more effective antibacterial properties and biotechnology could be useful in producing these metabolites. The present study aimed at investigating the effects of rhamnolipid microbial surfactants in a cream-based formulation on growth inhibition of Staphylococcus aureus using in vitro and animal models.

The inhibitory effects of rhamnolipids produced by Pseudomonas aeruginosa MR01 on the growth of S. aureus were investigated by disk diffusion method. Then, the effects of dirhamnolipid compounds on the survival and morphology of bacteria were studied using estimation of colony forming units (CFUs) and scanning electron microscopy (SEM). The di-rhamnolipid-containing cream was prepared and its effects on inhibition of the bacterial growth was evaluated in in vitro and animal subjects.

Disk diffusion tests showed a minimum inhibitory value of 30mg/disk for aqueous solutions of mono- and di-rhamnolipids, and 20mg/disk and 10mg/disk for mono- and di-rhamnolipid solutions in Dimethyl sulfoxide (DMSO), respectively. The aqueous solution of di-rhamnolipids at 20mg/ml resulted in lack of viable cells of S. aureus. SEM images showed changes in spherical shape of S. aureus during rhamnolipid treatments. Di-rhamnolipid-containing cream led to inhibition of bacterial growth in vitro on agar medium. Moreover, findings in rats indicated inhibition of bacterial growth in wound areas after 20 days of treatment with the cream.

In current study, Di-rhamnolipids demonstrated inhibitory effects on the growth of S. aureus. These compounds in cream formulation could also have antibacterial effects.

 Rapid repair of skin donor sites in partial-thickness skin grafts in burn is critical to the patient. Severe pain during dressing change and scarring also reduce the quality of life and treatment. Recently, nano-silver particles are available which have a high surface to volume ratio and remain effective even at a very low concentration and minimize the chance for tissue toxicity due to silver. Our aim in this study was to evaluate the effect of nano-silver dressings on increasing the rate of repair and reduction of complications in non-infectious wounds of skin graft donor sites.

 This was comparison study that involved patients admitted to a single-center burn unit who required a skin graft donor site. 10 burn patients with thermal injury and 10-30% of total body surface area (TBSA) who referred to Shahid Motahari Hospital, Tehran, in 2016 were studied. Each patient was compared to herself. After anesthesia, the site of the skin graft was randomly divided into three sections in each patient and was covered with Agicoat®, Mepitel and vaseline gauze. On the 4th and 8th of the day, the pain was recorded during the dressing change on the basis of the visual analogue scale (VAS). After 6 months, the patients were evaluated for the remainder of the scars based on VSS (Vancouver scar scale).

 The mean time to repair in both groups were similar and significantly shorter than that of vaseline (P=0.005). The pain comparison between groups showed that on the fourth day, the mean pain in the Agicoat group and Mepitel was significantly less than the Vaseline group (P=0.004). Also, the mean pain of the epileptic group was significantly lower than that of the Vaseline group (0.002). However, there was no significant difference between the duration of regeneration and pain between the two groups of Agicoat and Mepitel, but there was no significant difference between the mean pain on the 8th day and the mean VAS 6 months after the graft.

 Agicoat dressing has been effective in reducing pain and increasing the repair speed, but this effect was similar to that of the silver-free Mepitel dressing. Expensive silver nano-crystal dressings limit their use. The silver nanocrystal did not have much effect on improving the remaining scar. However, more studies are needed in this regard.

The research aimed to proposing a conceptual model for application of semantic technology in information retrieval in the digital libraries. This investigation is a practical sort. The tool which is used for gathering the data is the checklist that is used in the field of meaningful technological practical in marketing information in digital library softwares, this is under the observation of experts, in addition, the method of Delphi is used in this investigation in 3 fields which are meaningful technological architecture, Data were analyzed using structural equation analysis of variance-axis, partial least squares modeling (PLS -SEM) was used. A combination of two views of the final model of research was developed. The semi-structured interview and Descriptive Statistics was used to validate the final model and validate it. The fitting of both parts of the data algorithm and the results of the confirmatory factor analysis shows the desirability and acceptability of the structure at the level of the indicators and components. The goodness of fitting the model from the viewpoint of the members of the Delphi Panel is 0.589 and the goodness of the fitting of the model from the viewpoint of software professionals is 0.387, which amounts to 0.01, 0.25, and 0.36, respectively, as weak, moderate and strong values for The GOF demonstrates the overall robust fit of the model. Therefore, it can be used as a suitable template for the use of technology meanings in restoring digital information.

Introduction & Burns are usually considered as the most violent trauma. Wound healing is a complex process that is usually associated with various growth and biological factors. During the process of wound healing, the dressing used for restoration and repairing tissues of the dermis and epidermis of wound. Medicinal plants provide initial treatment compared to synthetic materials are inexpensive, safe and natural can be a source of useful and effective in the treatment of burns. The aim of this study was to evaluate the effects of Adib Derm on the healing of full- thickness second degree burn wound in Rat.
In this experimental study which was performed in the animal lab of the Hazrat Fatemeh Hospital in Tehran, 24 adult male rats with an approximate weight of 250- 300 grams, with deep burns of 2 cm 4×2 dimensions were prepared and divided into 2 groups of 12. We used Adib derm (Adib exir pharmaceutical company - Iranian scholar) in first group and Vaseline gas in the second group (control) to dressing every day until healing is complete and the wound healing process by shooting as every 7 days with Image J, ver. 1.45, (NIH, Maryland, USA) was monitored. On 14 and 28 to determine the amount of collagen and inflammatory cells were sent for pathological sample from burn wounds.
The results showed that during days 7 to 21 in each group reduced wound size (P According to the results of the present study, the effect of this ointment on the recovery of burn wounds was not as much as we expected. Thus, it is suggested that further studies perform with a larger sample size and with the change in the method of dressing and superficial burns.

Burns is a major health problem due to severe side effects and limited financial resources. Some herbs are cheap and available, such as Arnebia euchroma can be effective treatment of burn wounds and reduce recovery time. The aim of this study was to evaluate the effect of Arnebia euchroma ointment on healing of deep second-degree burn wound in rats.
This experimental study was conducted in animal laboratory of Hazrat Fatemeh Hospital in 2015, Tehran. In this study 24 male Sprague-Dawley rats weighing approximately 300 to 350 g were selected. After general anesthesia, back of each rat was shaved with clipping device. Then second-degree burn with the area of 2×4 cm was induced on them. Rats were randomly divided into 2 groups, 12 in each. The surface of the wound in the first group was covered with Arnebia euchroma ointment and in the second group with Vaseline. Dressing was done daily until complete recovery and the wound healing process was monitored by photographing every five days. On day 20, the samples were sent for pathological evaluation of the amount of collagen and inflammatory cells.
Results showed that, during days from 5 to 15 the extent of the wounds reduced in both groups (P= 0.000). The reduction of wound size was significantly higher in Vaseline group compared to Arnebia euchroma ointment group (P= 0.040). The results of the pathological examination showed no significant difference in the amount of collagen and inflammatory cells in the two groups.
It seems Arnebia euchroma ointment to some extent reduced the extent of the wound especially in superficial burns compared to other dressings. However, it is better to conduct more similar studies with a larger sample size and different method and change in timing of dressing.

High costs of treatment and rehabilitation lead to increased tendency of researchers in complementary therapies and using the compounds which have natural origin and are cheaper. Sheep ghee, known as yellow oil, is one of the compounds used in many parts of Iran for wound healing. Considering that few studies have been performed on the effect and rate of these materials on burn wound healing, the present work is aimed to investigate the effect of ghee on burn wound healing in rats.
In this experimental study which was performed in the animal lab of the Hazrat Fatemeh Hospital in Tehran, 36 adult male Sprague-Dawley rats with the relative weight of 250-300 g were selected and second-degree burn with the area of 2×4 cm was induced in them. Then, they were randomly divided into 3 groups, 12 in each. To dress the burn point in 1 to 3 groups, silver sulfadiazine cream, ghee, and Vaseline were used, respectively. The evaluation process was monitored by photography with 5 days intervals using an accurate ruler and ImageJ software, version 1.45 (National Institutes of Health, Bethesda, Maryland, USA). On the 17th and 30th days, Tissue biopsies was performed for the epithelialization rate, degree and arrangement of collagen, and chronic and acute inflammatory cells, the sample of burn wound was sent for pathological investigation.
Results showed that, wound area was significantly reduced in ghee, and Vaseline groups compared with silver sulfadiazine cream on days 5th, 15th, and 25th (P= 0.001). however, the difference between ghee and Vaseline group was not significant. In the 17-day time period, results of collagen arrangement (P= 0.000) and epithelialization results (P= 0.04), acute inflammatory cells (P= 0.001), and fibroplasias (P= 0.000) in 30th day were significantly better in ghee, and Vaseline groups.
This study showed that, in contrast to the public belief in some regions in Iran, ghee could not accelerate healing of burn wound and promote histopathological indices. Therefore, they are not recommended.

Education can play a major role in improving the quality of nurse's performance. The present study aimed to determine the effect of hand dressing education through group and video training on nurses working in different wards.
In this quasi-experimental study with two groups, 90 nurses working in different wards of Hazrat Fatima in Tehran were selected by census method and randomly divided into two groups: video and group training. Data collecting instrument was a questionnaire to assess the knowledge and performance checklist to evaluate nurses and researchers’ performance before and after the training. Data were analyzed using SPSS software ver19 , Paired-Samples T test and independent t-tests.
The level of awareness in the training group before and after training were 17.20 ± 1.75 and 18.16 ± 1.14 and in the video training group it was 17.07±1.48 and 17.93 ± 1.45. The performance of training group before and after training was 77.89± 9.36 and 81.69±8.41 and in the video training group it was 74.47±10.79 and 80.33±9.36. The results of both groups after the training was better. (P Although both groups were effective in raising nurses’ awareness and performance; however, according to numerous advantages of video training including affordability and ability to watch videos at any time and place, etc., using this method in the training programs is recommended.

Cartilage grafts is one integral component in the various fields of plastic surgery particular rhinoplasty. Surgeons usually use from various sources, including the septum of the nose, ears and rib. Complications such deformity and reabsorbtion may be created with use of the cartilage. Area of the removal of cartilage can prevent these complications. The aim of this study was to compare the absorption rate and viability of cartilage autograft between two common donor site, the rib and the concha.
This experimental study was performed on October 2014 in animal laboratory of Hazrat Fatima Hospital, Tehran, Iran. In this study, 15 New Zealand white male rabbits, weighing 2000-2500 g, approximately 12 to 16 weeks of age were used. In each rabbit, a piece of one ear and one cartilage was excised. After careful weighting of grafts, we implanted the rib cartilage graft into the left pocket and the conchal cartilage graft into the right one. After 8 weeks, the grafts were removed and weighed precisely and photography was carried out. The specimens were fixed in 10% formalin solution for histologic examination was. An example of hematoxylin and eosin staining and cut (H&E) were performed and samples of live chondrocytes and fibrosis were examined by a pathologist.
We lost 3 rabbits during our study. The results showed that the average weight of a graft from the ear within 2 months, but this increase was not statistically significant (P= 0.152). In the rib graft weight loss over 2 months, and this reduction was statistically significant (P= 0.009). The resorption between two group was not significant but the amount of fibrosis was more in conchal cartilage graft.
According to the study it can be concluded that absorption rib cartilage is somewhat better results than the cartilage of the ear. More studies, in addition to cartilage implants longer human studies can contribute to more accurate conclusions.

Acute and chronic wound healing has always been problematic. Stem cells with or without the scaffold carrying these cells have been proposed as new methods in the treatment of wounds. In this case study we have tried to examine the effect of scaffold made of polyether sulfone (PES) alone, with stem cells and along with stem cell and growth factor on wound healing in rats.
This experimental study was conducted in Animal Laboratory of Hazrat Fatemeh Hospital in 2012. In this study, 48 rats were randomly divided into four groups. A wound created on the back of each rat at the size of 3×3 cm. The surface of the wound in the first group is covered with PES seeded with adipose-derived stem cell (ASC) and growth factor (GF), in the second group with polyether Sulfone seeded with ASC, in the third group only with PEWS, and in the fourth group (control) with Vaseline gauze. On 20th and 35th days, the surface of the wound was assessed by photography in order to understand the process of healing. In addition, on days 20 and 45, the histopathology characteristics of the samples were studied with a biopsy of the wounds.
The Results of wound healing in the control group was better than the other groups and its statistical difference between others was meaningful. (P=0.008, P=0.013, P=0.001) On day 20, by examining histopathological characteristics including epithelialization, the number of inflammatory cells, the amount of angiogenesis and collagen synthesis in control group, we gained better results. (P=0.000), But on day 45, the results in different parameters were not equal.
polyether sulfone scaffold alone or with adipose-derived stem cells couldn’t improve the process of wound healing. Also adding vascular endothelial growth factor (VEGF) did not change the results significantly.

Tissue expansion is a common reconstructive surgery especially in burned patients. This study has been designed to evaluate the rate of complications of this method in Hazrat Fatima Hospital between 1389-1391.
In this cross sectional and retrospective study, 150 patient's records have been studied between 1389-1391 years, frequency rate and types of complications related to tissue expander have been surveyed in these patients.
Complications have been observed in about 7% of the patients included in this study. Exposure of tissue expander was the most common complication (81.8%). Other complications which are resulted from this issue are capsular contracture and infection. Age was the only factor which had significant relation with increasing complication among the other surveyed factors including age, sex, indication of operation, wound location and duration of anaesthesia.(p=0.033)
The incidence of complication in patients that required tissue expander was not high and it was less than 10%. It should be noted that patient selection should be carefully in paediatric group and also strict observance of surgical principles is necessary to avoid complication.

Graft survival has been considered the major problem in reconstructive surgery. Clinical studies have helped us to understand the role of PRP in increasing skin survival. Our goal in this study was to examine the treatment effects of platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) on autologous full thickness skin graft survival in male rats.
This experimental study was performed on 36 rats of Sprague-Dawley race with weighing approximately 250 to 300 gr on May 2015 in animal laboratory of Hazrat Fatima Hospital. After anesthesia, rats were divided into 3 groups. We injected platelet-rich plasma (PRP) in the first group, platelet-rich fibrin (PRF) in the second and saline in the third group after removing the skin. Microscopic analysis was performed with camera (Canon powershot SX200, Tokyo, Japan) on days 7, 14, 21 and 28 after surgery. We used image analysis system (ImageJ, ver. 1.45) to examine necrosis and survival rate. Samples were studied with H&E staining on day 28 microscopically for histological analysis of vascular density and angiogenesis.
Our findings showed the area of necrosis in animals injected with PRP on days 7 and 14, was meaningfully less than control group (P= 0.0001). There was no meaningful difference between control and PRP groups (P> 0.05). The area of necrosis in animals injected with PRF did not have any significant difference with control group from beginning to 21st day (P According to our results in this study, we can conclude that using autologous PRP can enhance the process of healing soft tissue injury and be affective at increasing graft survival. This method is suggested to be conducted for patients highly at risk of graft loss and also for those who are in need of early treatments.

Coriander with the binominal name of Corianda Sativum, is one of the oldest medicinal plants ever known to man. Anti-inflammatory, anti-microbial, and anti-fungal effects of its oil has been mentioned in numerous studies. This study examines the impact of coriander cream on wound healing of the second-degree singe burn. In this experimental study which was performed in the animal lab of the Hazrat Fatemeh Hospital in Tehran, 48 adult male rats with an approximate weight of 250-300 grams, with deep burns of 2 cm 4×2 dimensions were prepared and divided into 4 groups of 12. We used silver sulfadiazine cream, alpha ointment, coriander cream and vaseline gauze (control group) dressings in burn wound of the groups 1 to 4 respectively. At the end of the study (30 days), rats were euthanized with a high dose of thiopental and the wounds were evaluated on days 10 and 17 with a punch biopsy. Samples were fixed with 10% formalin on histopathology slide using haematoxylin and eosin (H&E) staining (to assess and determine the presence of inflammatory cells). The amount of fibrin and collagen at the site were evaluated using a software program ImageJ, version 1.45 (National Institutes of Health, Bethesda, Maryland, USA). The mean of wound surface area in the first photography was no significant (P= 0. 135). The rate of wound healing in alpha ointment and coriander cream had better outcomes than either of the other two groups (P= 0.000). The healing of the wound in silver sulfadiazine group was significantly less than other groups. Pathology results showed a statistically significant difference between the four groups (coriander, alpha, SSD and control), based on the Kruskal-Wallis test. These relate to (1) polymorphonuclear in the first (P= 0.032) and the second series (P= 0.003), (2) Angiogenesis in the second series (P= 0.004). (3) Fibrosis in the first series (P= 0.024) and the second series (P= 0.000). The results of this study showed that wound healing improvement in coriander cream group was better than the control group and silver sulfadiazine group; and similar to alpha ointment group.

The present study aims to investigate the personal and professional skills of special library administrators from the view of provincial governorates libraries administrators of the country and library professors according to their management skills. the research Method was descriptive survey. For collecting data, the researcher has made a questionnaire that determines the required management skills of managers in the three components of cognitive, humanity and technical skills. The population of this study included all the provincial specialized libraries’ managers (31) and library and information sciences’ professors (170); for the first group of population, because of the limited number of samples, Cochran and for the second group of population census method were used. Validity confirmed by Some Professor and It’s Reliability Confirmed by %94 Cronbach Alpha, Data were analyzed by using SPSS Software and the inferential statistics like independent sample t-test and ANOVA were used too. Findings showed that the highest priorities in terms of management skills were humanity skills (4.35), perceptual skills (4.17) and technical skills with mean of (3.93). In addition, from the library managers’ point of view, the highest priorities are humanity skills (4.45), technical skills (4.24) and perceptual skills with the mean of (4.09). There was not a statistically significant difference between library professors and special libraries managers’ point of views according to their personal and professional skills.

The present study aims to explore and compares views of special library administrators and LIS academics about human and technical skills required for the management of special libraries. The questionnaire designed to collect data had three components: cognitive, human, and technical skills. A sample of 118 special library administarors and LIS academics was drawn out of a population of 31 of the former and 170 of the latter. Data was analyzed using SPSS application. Findings showed that the highest priority is given to human skills (4.35) by both groups, then to technical skills (3.93). From the point of view of practioners, the figure was 4.45 for human skills and 4.24 for technical skills. No statistically significant difference was noticed between the academics and the practioners views.

Introduction & Regeneration of skin tissue is important in the plastic and reconstructive surgery and random skin flap pattern is one of the most common procedures in plastic and reconstructive surgery. Necrosis of the skin flap is an inevitable complication after the surgery. Several factors such as ischemia, insufficient blood flow and venous concentration are causes in necrosis creation. Pharmacological agents and modifications of procedures have been proposed to avoid this complication. In this study, the effects of Angipars cream on skin random flap survival were examined in rats. Twenty male Sprague – Dawley rats were selected and randomly assigned to two equal groups. Surgery was done under general anesthesia and a rectangular 2×7 cm flap was generated on the back of each rat and it was sutured once again. Angipars cream was used on flap pedicel in control group and Vaseline was used in the other group for ten days. The mean and standard deviation was used to assess the test data and independent t-test was used to compare the groups. During the study, one rat of the control group died. There were no cases of infection or hematoma. The necrosis rate of the angipars group was 28.86 ± 6.43 percent and in the control group was 25.3 ± 10.52 percent. There was no significant difference in necrosis rate between the two groups. Angipars cream has no effect on increasing perfusion of random flap. Furthermore, also increased angiogenesis was not observed in this study.

Introduction & In recent years the use of diced cartilage grafts in rhinoplasty have been considered by most plastic surgeons. For preventing dispersion of diced cartilages، many authors recommend the use of various wrapping such as temporalis fascia، surgicel or alloderm to cover diced cartilage grafts. The aim of this study is to compare the absorption rate and viability of cartilage autograft between two groups of unwrapped and fascia wrapped diced cartilage graft. In this study، 15 rabbits، of age between 12 to 16 weeks of age were used. One ear of each rabbit was excised and denuded of skin and perichondrium، then it was divided into two equal pieces and were diced. One group of the grafts were covered by rabbit fascia Lata and the other group left was without coverage. Two subcutaneous pockets were created on each side of lumbar vertebrae. After precise weighing of specimens، wrapped and unwrapped diced cartilages were implanted into separate pockets on the each side rabbit vertebra coloumn. After 12 weeks، the grafts were removed and weighed precisely and samples were stained with H&E and were examined histologically by pathologit. The absorption rate of fascia wrapped diced cartilage grafts was significantly more than the case of unwrapped diced cartilage grafts (P-value < 0. 001). Unwrapped diced cartilage graft had some growth، but it wasn’t statistically significant (P-value = 0. 09). New cartilage formation in the unwrapped group was significantly more than the case of fascia wrapped group (P-value = 0. 001). But in terms of cartilage integrity، cartilage viability، fibrosis and ossification no significant difference was found between two groups. Our study objectively proves that wrapping around implanted diced cartilage graft may act as a barrier and impedes nutrients to reach to the chondrocytes. Since there was no resorption in the unwrapped diced cartilage group، we recommend it as a good method for restoring profile in rhinoplasty surgery.
