ABSTRACT
Introduction: Use of computer has been increased in recent years. So understanding the related factors to use computers is important. The aim of this study was to determine related factors to use computer based on "Technology Acceptance Model".
Materials and Methods: This is a descriptive-correlational study which 100 staff membersof Shahid Beheshti University of Medical Sciences were selected through convenient sampling method. Data were gathered using demographic questionnaire and "Technology Acceptance Model Scale" with 43 items. Content and face validity of the questionnaire and the reliability of the instruments were determined by internal consistency and test-retest methods, respectively.
Findings: There were a direct and positive correlation between perceived usefulness[Beta = 0.309], perceived ease of computer [Beta = 0.309], with computer attitude, and also computer attitude with intention to use computer [Beta = 0.503].
Conclusion: There is a direct and positive correlation between usefulness and ease of use of computer with computer attitude and ultimately intention to use computer. Attention to increase computer attitude for using computer is suggested.
ABSTRACT
Introduction: Long term or excessive stress is harmful for human life. It causes behavior and emotional changes. It plays a main role in people suicide. Women not only are vulnerable in society but also face more stresses. Recognizing the nature of these experiences is necessary to find health and safety needs, also prevention of suicide effects.

Information resources include women saved from suicide who were confined to bed in hospitals of Isfahan Medical Sciences University. Purposive Sampling had been continued to saturate information. Finally 10 people had participated in this study. Data was collected by using in-depth interviewing and was analyzed by "Colaizy" method. We tried to analyze qualitative data based on valid criteria
Results: The findings of this research were summarized into four core concepts: life in stress that created from two cluster of internal and external stress, confront against stress have two clusters that included of adaptation and in adaptation behavior
Conclusion: Findings of this study showed that participants by using effective adaptation behaviors in critical conditions or confront against tremendous stresses [specially, resorting to spirituality's experiences] had lower injuries than the others.

ABSTRACT
The regular physical activity can lead to physical, psychological and social health. Studies have shown that%80 of Iranian people does not exercise. Therefore, due to the importance of exercise performance and concepts of Theory of Planned Behavior, different studies are needed regarding its related factors according to a theoretical framework. The aim of this descriptive correlational study was to determine factors related to exercise performance according to the Theory of Planned Behavior in female students in 2009. 444 female students were selected by stratified sampling method. Data collection tool was a questionnaire including 6 parts: 1- external variables, 2-attitiude to exercise, 3-subjective norms of exercise, 4- perceived control behavior toward exercise, 5- intention to exercise, and 6- exercise. Content validity index, face validity and reliability of the tool were identified by internal consistency and test-retest methods respectively. Data were analyzed by SPSS [ver. 15]. Mean, standard deviation, distribution of frequency, regression and path analysis were calculated in data analysis. Attitude and control of perceived behavior were positively correlated with intention to exercise and subjective norms, controlled perceived behavior regarding exercise as well as intention to exercise were positively correlated with exercise performance. Furthermore, control of perceived behavior was indirectly correlated with exercise performance through intention to exercise while subjective norms had no correlation with exercise performance. Providing positive attitude and increasing the control of perceived behavior regarding exercise can motivate people to do it
