One of the assessment methods of service quality in organizations is the gap analysis tool. The current research was conducted with the aim of designing and evaluating validity and reliability of the service quality assessment tool in libraries and medical information centers in universities of medical sciences according to the gap analysis models.

A cross-sectional study was performed to evaluate the validity and reliability of the service quality assessment tool of libraries. It is considered as a tool development study that was carried out between July and September 2023. The statistical population included the users of the central library and document center of Hamadan University of Medical Sciences (students, faculty members, and staff). First, the desired tool was designed through reviewing gap analysis studies and models (LibQUAL, DigiQUAL, and LibQUAL), which are service quality assessment models from the customers' point of view, and assessing services that can be provided in the libraries of medical sciences universities. Afterwards, it was sent to 15 librarians and library staff to estimate the validity of its content (CVI & CVR). To estimate its reliability (internal consistency), Cronbach's alpha was calculated. 

The study tool included eight main domains and 76 items. According to the results obtained in the validity study of the questions, the CVR score was 72items higher than the number of the Lawshe’s table (0.49), and all these items were confirmed. The scores of four items were lower than the number of Lawshe’s table, so they were excluded from the questionnaire. In the CVI assessment, all components scored above 0.79. The internal consistency (Cronbach's alpha) of the items with a reliability of over 0.90 revealed that all eight main domains and 72 questions had the necessary validity.

The results demonstrated that the service quality assessment tool of libraries in medical sciences universities has the necessary validity and reliability properties. Therefore, it can be used as a suitable tool for measuring the quality of library services.

Professional practice in nursing requires familiarity with the ethical issues of nursing profession and their sensitivity to patients. This sensitivity, as the basis of nursing ethics, should be considered from the beginning of nursing education. The degree of adherence to one's religion and the level of one's beliefs appear to be factors influencing moral sensitivity. The purpose of this study was to determine the relationship between spiritual health and moral sensitivity of nursing students.

In this descriptive-analytical study, 123 nursing students of Hamadan University of Medical Sciences were enrolled. Data were collected through questionnaire demographic information, Poultzan and Erison spiritual health questionnaire and moral sensitivity questionnaire. The data were analyzed by Chi-square and Pearson correlation coefficients using SPSS 21 software.

The mean age of participants was 23.69±4.55 years. Most nursing students had moderate spiritual health score and moral sensitivity. There was a positive and significant correlation between spiritual well-being with nursing students 'moral sensitivity (r=0.26, P=0.003), meaning that the higher the students' spiritual health score, the higher their moral sensitivity.

The results showed that spiritual health is an important parameter in promoting the moral sensitivity of nursing students. Therefore, promoting religious beliefs improves the health status of students and thus plays an important role in the implementation of effective patient care. In the promotion of their health, the spiritual aspect should also be taken into consideration.

The commonest malignant cancer in the lower gastrointestinal tract is colorectal cancer which is the third cause of death due to cancer in the world. The incidence of this type of cancer in Iran has increased during last recent years. The prsent study aimed to detemine prognostic factors of colorectal cancer based on weibull distribution with nonconstant shape.

In this article we analyzed survival of 1060 patients with colorectal cancer who registered in Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences (Tehran, Iran) from 2004 to 2015. Weilbull parametric model with non-constant shape parameter were used for determination of prognostic factors. The results were compared to regular Weibull distribution and the best method were choosed based on AIC criteria.

On constant shape parameter, age at diagnosis, tumor size and the tumor site had effect on survival time with AIC of 20037. On non-constant shape parameter, sex, age at diagnosis, tumor size, the tumor site and the body mass index were significant on survival of these patients with AIC of 19994.

Remarkably, based on these data and AIC criteria, the Weibull with non-constant shape parameter chose so that sex, age at diagnosis, tumor size, the tumor site and the body mass index of these patients were recognized as prognostic factors in their survival

Colorectal cancer is the most common cancer of digestive system in Iran.The incidence of this cancer has increased in recent years.The aim of this study was to evaluate the survival rate and to define the prognostic factors in Iranian colorectal cancer patients using competing risk model.
Data recorded from 1060 patients with colorectal cancer who registered in Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences (Tehran, Iran) from 2004 to 2015 in a retrospective study. Analysis was performed using competing risks model. Software used for data analysis was STATA, and significance level was regarded as 0.05.
The result indicated that, at the end of follow-up, 380 (35.8%) death was from colorectal cancer and 49 (4.6%) death was due to other diseases and 631 patients (59.5%) survived till the end of the study. The mean survival time for a patient in 1060 was 56.96±1.46 month with median equals 45.5 months. According to competing-risks method, only age at diagnosis and body mass index has a significant effect on patient’s survival time.
: In order to identify the prognostic risk factors on the survival of patients with colorectal cancer, in presence of competing risks, using the competing risk regression model was found more efficient compared to cox regression model.

Analysis was performed using competing risks model and based on the Weibull distribution. Software used for data analysis was R and significance level was regarded as 0.05.
The result indicated that at the end of follow-up, 380 (35.8%) deaths were from colorectal cancer and 49 (4.6%) deaths were due to other diseases and 631 patients (59.5%) survived till the end of the study.

According to competing-risks method, only age at diagnosis and body mass index has a significant effect on patient’s survival time.
Based on parametric competing risk model, just age at diagnosis and body mass index were significant prognosis of colorectal cancer survival.
