  • Design lifttime of a wind turbine is required to be at least 20 years. In the meantime, the wind turbine will experience a lot of load cases such as extreme loads and fatigue loads which will include several typhoons per year and extreme gusts with 50 years recurrence period as well as endless turbulence flow. Therefore, IEC61400-1 specifies design load cases to be considered in the wind turbine design and requires the wind turbine to withstand the load cases in various operational situations. This paper investigates the ultimate loads which the wind turbine will experience for 20 years and their characteristics based on the IEC61400-1 using an aero-elastic software, GH-Blade. And the performance characteristics of a wind turbine such as electrical power generation and annual energy yield are also investigated.

  • The aims of this study are to investigate the impact of the experience of exposure to domestic violence(witnessed interparental conjugal violence and child abuse) on mental health among college students, and to explore whether social support acts as a moderator between domestic violence and mental health. Through this process, I intended to provide a reference base to suggest substantial interventions for family welfare by helping students to overcome negative domestic violence exposure experiences and adapt as healthy members of society. To achieve this goal, the study established a conceptual framework by considering the mental health of adolescents with domestic-violence exposure experience as a dependent variable, domestic violence exposure experience (witnessed interparental conjugal violence and child abuse) as an independent variable, and social support as a moderator of the relationship between these two variables. The subjects composed 747 college students in 8 colleges in Seoul. The main summary of this study is as follows: First, according to the analysis of domestic-violence exposure experience, all the subjects of this study had substantial experience of violence at home and witnessed interparental conjugal violence. These students scored 3.83 points in social support, higher than the median of 3, implying that these students had a higher awareness of social support. Moreover, their mental health score was 3.50 points, which is higher than the median of 3, indicating a somewhat positive tendency toward mental health. Second, to explore the moderating effects of social support between child violence experience and mental health, gender, age, financial status, academic-performance, child abuse and social support were input in the first step, and then buffering effects were examined by entering an interaction term to the first step in the second step. There was a significant interaction between social support and mental health. Therefore, social support was identified as having moderating effects on the relationship between child violence and mental health. Third, the analysis of moderating effects of social support between witnessed interparental conjugal violence and mental health revealed that social support had a positive influence on mental health in the first step. By contrast, the interaction term of witnessed interparental conjugal violence and social support showed no significance, indicating no moderating effect of social support in the second step. To sum up, social support served as a moderator for mental health among college students with child abuse experience, but had no moderating effect on witnessed interparental conjugal violence experience.

  • Objectives: The purpose of the study is to investigate the cardiopulmonary resuscitation(CPR) knowledge and performance in the dental hygiene students in Gyeongju. Methods: A self-reported questionnaire was completed by 106 dental hygiene students in Gyeongju. The questionnaire consisted of CPR knowledge and performance, and was collected from April 4 to 12. The data were analyzed using SPSS version 18.0 by t-test, correlation analysis, ANOVA, and multiple regression analysis. Results: The average age of the subjects was 20.6 years and 97.2% were female students. The students did not experience the emergency situation(96.2%). Approximately half of the students received CPR education(51.9%), but they did not have the CPR certificate(94.3%). There was a significantly statistical correlation between the CPR knowledge and performance(p<0.01). The CPR knowledge was proportional to the CPR performance skill. The CPR knowledge (p<0.05) and performance (p<0.01) showed a statistical difference by the grade of the students. The CPR knowledge of the senior students was higher than that of the freshmen and sophomore. The CPR knowledge (p<0.01) and performance (p<0.01) showed a statistical difference by the education experience. The CPR education provided the students with CPR knowledge and performance. Conclusions: In order to promote and maintain CPR knowledge and performance on dental hygiene student, it should be reinforced the more systematic training program which can be repeatedly evaluated and retrained than the present. In addition, a follow-up study will also be needed for the student and clinical dental hygienist.

  • Purpose : Using qualitative research and a phenomenological approach, the present study aimed to explore men's experiences of becoming a nurse. We posed the question "What has been your experience of becoming a nurse?" Methods : Eleven male nurses from three regions in Korea were selected through convenience sampling. The protocol suggested by Colaizzi was used for data analysis. Results : The principal themes were "Challenging to the stochastic stereotype of gender mechanics," "Floating outside the enclosure of multiple groups," "The male nurse's conceptualization of nursing organizations," "To stand with self-doubt, thinking of it as a stopover," and "Situations encountered by a male nurse." Conclusion : Men experience gender discrimination based on the social roles that are imposed on males and females both at school and in the workplace. They prefer to work where they have more diverse tasks that require quick responses. However, most male nurses adapt to this work by outlasting the difficulties. These nurses become accustomed to their tasks, and satisfied with their mature work performance. They often feel they are not adequately compensated for their work. They may judge the future as uncertain, and have lingering doubts about maintaining their positions, ultimately gravitating toward specialized fields that promise a brighter future and are more consistent with traditional gender expectations.
