Febrile seizure (FS) is the most common childhood seizure disorder that occurs in 3-4% of children .The aim of this study was to determine the effect of intermittent oral anticonvulsant Levetiracetam in prevention of the recurrence of febrile seizure (FS) in children.

This a randomized clinical trial study was conducted on 108 children with FS referred to the pediatric department of Mohammad Kermanshahi Hospital in Kermanshah in 2020. Then, eligible patients were divided into intervention (Levetiracetam; n= 72) and control (Acetaminophen; n= 36) groups using balanced block randomization. The intervention group received a dose of 30-60 mg/kg Levetiracetam during the febrile illness for prophylaxis for 9 months. In contrast, in the control group, only acetaminophen was prescribed just to reduce fever. Finally, the number of FS recurrences were studied in two groups. The data were analyzed using SPSS 26.

 The mean (±S.D) age were 2.37 (±1.01) vs. 2.30 (±0.95) years in the intervention and control groups; respectively. The number (%) of boys in the two groups under study was 39 (54.1) and 19 (52.7), respectively. The mean time to first seizure recurrence after the intervention was significantly longer in the intervention group (5.70 ± 0.82 months) than in the control group (2.32 ± 0.75 months) (P-Value<0.05). Also, the mean number of recurrences of FS in the intervention group (2.25 ± 0.80) was significantly lower than the control group (4.13 ± 0.79) (P-Value<0.05).

The administration of oral anticonvulsant Levetiracetam may be effective in the reduction of the recurrences of FS, however, detailed studies in this field is recommended.

Growth parameters of cuttlefish (Sepia pharaonis) was estimated from northern Persian Gulf, (27˚ 50´ 06˝ and 30˚ 06´ 07˝N to 52˚ 02´ 56˝and 50˚ 05´ 14˝E) from October 2017 to May 2018. 100 to 150 specimens were randomly separated each time from total catch and mantel length and body weight were measured by sexes. Based on the Von-Bertalanffy growth formula in males, growth parameters were estimated with K=0.3 year-1 and L∞=37 cm. In females, growth coefficient, K and asymptotic length, L∞ were estimated 0.5 year−1 and 30 cm respectively. Maximum of fishing effort was observed in November 1.08±0.71 kg per trap and minimum was 0.06±0.02 kg per trap in May. Maximum catch per trap was 0.65±0.56 kg in 21-30 m depths and minimum was 0.10±0.05 kg in 41-50 m depths. Low growth coefficients in males and females show that this species reached to maximum growth during presence in the study area. Also, its aggregation in the depths of 30-21 m indicates the accumulation of mature spawning specimens in the area, which needs serious protection.

In this study, yttrium aluminum garnet (YAG) was prepared using a facile electrochemical technique. Four samples were synthesized in 0, 20, 40 and 60°C by electrochemical pulse deposition and were then calcined at 1200°C. The effect of synthesis temperature on morphology and structure of YAG was studied using X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy (SEM) techniques. Furthermore, the electrochemical performance of samples was investigated by cyclic voltammetry and square-wave voltammetry methods. Structural analysis shows that by increasing the synthesis temperature, the network structure of the samples changes from amorphous to the crystalline structure. SEM results also affirm the structural change and show particle size increase in YAG samples from about 90 nm to 2 µm, as a result of rising electrodeposition temperature. The influence of the observed network structure alteration on the catalytic performance of samples was also found to be very significant. Square-wave voltammetry electrochemical analysis of YAG samples leads to enhanced electro-oxidation features, as a result of temperature increase at the synthesis stage. As a proof of concept, the as-prepared YAG samples were successfully employed for electrochemical sensing of ascorbic acid, which showed a significant rise in the electric current of the sensor.

Spiritual leaders by using cohesive performance's employees to their internal human values resulted to increased their commitment, motivation and organizational citizenship behaviors. Staffs commitment has powerful sense to their organization and its effects on increasing their performance. This behavioral phenomenon in health care organizations is valuable because quantity and quality of care is important in there. This main purpose of this study was to assessing the relationship between dimensions of perceived spiritual leadership (vision, faith / hope and altruism) with organizational outcomes (commitment, organizational citizenship behavior and performance) in clinical nurses. It was cross-sectional and descriptive study that was done in 2012.All of the nurses in Noshahr city were study population that (192) of them selected simple randomly. Data were gathered by four questionnaires; Spiritual Leadership Questionnaire (Fry 2005), it's reliability coefficient (92.4), Organizational Citizenship Behavior (Bell& Mengass 2002) it's reliability coefficient (87.6), Organizational Commitment Questionnaire and Questionnaire for Organizational Performance (Fry 2011) with reliability coefficients (76.1, 84.7) respectively. Data analysis with use SPSS 18 and AMOS 20 software and structural equation modeling method was done. The findings showed that the nurse's perception of spiritual leadership had relationship with organizational commitment and citizenship behavior. So, nurse's performance effected directly (β=0.87) in faith / hope domain in spiritual leadership and also, indirect relationship (0.60) in citizenship behavior effected their performance. Nurse's citizenship behavior (β=0.83) and organizational commitment (β=0.88) had more effect from altruism domain of spiritual leadership. Overall of model fitness showed c2/df equal with 1.65. Nurse managers and hospital administrators must be try for improving nurse's performance and organizational commitment. At first in planning with clarified goals (vision) and human relationship (altruism) improved nurse's perception in spiritual leadership. Because by this way they could facilitate organizational citizenship behaviors and also, delivery nursing care with high quality.

The Technology Acceptance Model (TAM) is one of the most influential measurement approaches for relating design alternatives to user acceptance of new information technologies or systems. The TAM emphasis on perceived usefulness and ease of use. The overall goal of this paper was to examine intention of the factors affecting electronic shopping by using the approach of expansion TAM. In this paper، in order to develop the technology acceptance model uses Security، consistency and normative beliefs as other aspects that have significant impact on the acceptance of electronic shopping. In this survey study 280 student of university of Isfahan who were selected by randomized stratified sampling، completed Teylor and Todd (1995)، Compatibility and Normative Beliefs Vijayasarathy (2004) and Security Salisbury (2001) questionnaire. The findings indicated that security، ease of use، consistency and usefulness are significant predictors of attitudes toward intention e-shopping and Normative beliefs had a positive effect on intention to electronic shopping. The Perception of examine intention of the factors affecting electronic shopping lead to improvement and development of these factors and encouraged users to more e-shopping.
