Differential Power Analysis(DPA) is powerful attack method for smart card. Self-timed circuit has several advantages resisting to DPA. In that reason, DPA countermeasure using self-timed circuit is thought as one of good solution for DPA prevention. In this paper, we examine what self-timed features are good against DPA, and how much we can get benefit from it. Also we test several self-timed circuit implementation style in order to compare DPA resistance factor. Simulation results show that self-timed circuit is more resistant to DPA than conventional synchronous circuit, and can be used for designing cryptographic hardware for smart-card.

This paper examined individual and social factors associated with children's anxiety, depressive symptoms, and self-worth. Seven hundred and thirty-eight 5th and 6th graders completed measures of affective problems, self-worth, styles of attribution, daily hassles, parenting, and social support. Regression analyses revealed that maladaptive styles of attribution and daily hassles were significantly associated with anxiety, depressive symptoms, and low self-worth. Results also indicated that social support played an important role in explaining depressive symptoms, emphasizing the role of social support of friends in preventing affective problems and enhancing self-worth. Results were discussed in terms of their implications for prevention and intervention.

Background: Health risks associated with unhealthy behaviours in adolescent and university students contribute to the development of health problems in later life. During the past twenty years, there has been a dramatic increase in public, private, and professional interest in preventing disability and death through changes in lifestyle and participation in screening programs. The aim of the study was to evaluate university students' health-promoting lifestyle behaviour for cancer prevention. Method: This study was carried out on university students who had education in sports, health and social areas in Celal Bayar University, Manisa, Turkey. The health-promoting lifestyles of university students were measured with the "health-promoting lifestyle profile (HPLP)" The survey was conducted from March 2011 to July 2011 and the study sample consisted of 1007 university students. T-test, ANOVA and multiple regression analyses were used for statistical analyses. Results: In the univariate analyses, the overall HPLP score was significantly related to students' school, sex, age, school grades, their status of received health education lessons, place of birth, longest place of residence, current place of residence, health insurance, family income, alcohol use, their status in sports, and self-perceived health status. Healthier behaviour was found in those students whose parents had higher secondary degrees, and in students who had no siblings. In the multiple regression model, healthier behaviour was observed in Physical Education and Sports students, fourth-year students, those who exercised regularly, had a good self-perceived health status, who lived with their family, and who had received health education lessons. Conclusion: In general, in order to ensure cancer prevention and a healthy life style, social, cultural and sportive activities should be encouraged and educational programmes supporting these goals should be designed and applied in all stages of life from childhood through adulthood.

Purpose: This study was conducted to develop and to determine the effects of an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention. Methods: Subjects consisted of 58 CAD patients (experimental group: 30, control group: 28). The experimental group participated in an integrated symptom management program for 6 months which was composed of tailored education, stress management, exercise, diet, deep breathing, music therapy, periodical telephone monitoring and a daily log. The control group received the usual care. Results: The experimental group significantly decreased symptom experiences and the level of LDL compared to the control group. The experimental group significantly increased self care activity and quality of life compared to the control group. Although no significant difference was found in cardiac recurrence, the experimental group had fewer recurrences. Conclusion: These results suggest that an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention can improve symptom aggravation, recurrent rate, self care activity and quality of life. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented in the overall transition period.

Purpose: The purpose of this study was to investigate the effects of the lifestyle modification coaching program on self efficacy, lifestyle and physiologic indexes related to the recurrence of stroke in patients with stroke. Methods: Sixty-one patients with stroke registered with a stroke center participated in this study. Of the participants, 32 were assigned to the experimental group and 29 to the control group. Self efficacy, alcohol drinking, smoking, physical activity, BMI (body mass index), WHR (waist-hip ratio), blood lipid level, and blood pressure were measured both for the baseline, as well as after intervention. The lifestyle modification coaching program consisted of an 8-week telecoaching session following face-to-face education. The control group received only the face-to-face education. Results: There were significant differences in physical activities, WHR, blood pressure within and between groups after intervention. The lifestyle modification coaching program had significant influences on blood pressure even after gender, age, and physical activity had been adjusted. Conclusion: The results of the study indicate that lifestyle modification coaching program is effective for physical activity, abdominal obesity and blood pressure. Therefore it can be used by nurses in hospitals and communities as one of the secondary stroke prevention programs for patients with stroke.

Purpose: This study is to investigate teachers' perception about bullying and education for bullying prevention. Methods: The subjects were 196 teachers who worked middle or high school in Seoul and Kyonggi province in 2008. We used self-administered questionnaires for bullying assessment that modified by the investigator. Chi-square and ANOVA test were performed to analyze the perception and education for bullying prevention. Results: The perception about bullying and education for bullying prevention of the teachers was examined in three domains; the perception about bullying's situation, cause, and solution. Teachers did not perceive bullying seriously but perceived that the main cause of bullying is personal characteristics. They recognized the solution of bullying is a responsibility for students, parent, teachers and society. The performance rate of education for bullying prevention was higher among teachers who perceived bullying seriously than the others. Conclusion: The teachers could recognize origin of bullying between students and also could solve this origin. So, teachers' role is very important than everything else to prevent bullying. Various education programs for bullying prevention should be developed.
