The numerous benefits of Savonius turbine such as simple in structure, has appropriate self-start ability, relatively low operating velocity, water acceptance from any direction and low environmental impact have generated interests among researchers. However, it suffers from a lower efficiency compared to other types of water turbine. To improve its performance, parameters such flow pattern, pressure and velocity in different conditions must be analyzed. For this purpose, a detailed description on the flow field of various types of Savonius rotors is required. This article presents a numerical study on a nonlinear two-dimensional flow over a classic Savonius type rotor and a Benesh type rotor. In this experiment, sliding mesh was used for solving the motion of the bucket. The unsteady Reynolds averaged Navier-Stokes equations were solved for velocity and pressure coupling by using the SIMPLE (Semi-Implicit Method for Pressure linked Equations) algorithm. Other than that, the turbulence model using $k-{\varepsilon}$ standard obtained good results. This simulation demonstrated the method of the flow field characteristics, the behavior of velocity vectors and pressure distribution contours in and around the areas of the bucket.

This study examined the retirement adaptation process for middle-aged and elderly couples. Twelve couples who had experienced retirement were recruited by theoretical sampling. Data were collected through in-depth interviews and analyzed through the grounded theory approach of Strauss and Corbin (1998). This study showed the results of 124 concepts, 41 sub-categories and 17 categories indicated through an open coding process. As a paradigm in axial coding, the causal conditions in the adjustment procedures of elderly couples whose spouses are retired were 'retirement preparation,' 'retirement acceptance,' and 'marital satisfaction.' A central phenomenon was 'crisis and conflicts of twilight couples.' The contextual conditions that correspond to this phenomenon were 'psychological separation from adult children,' 'division of household labor,' and 'economic status.' The action/interaction strategies to control the phenomenon were 'recognition of marital relationships,' 'conflicts coping,' 'resolution methods,' and 'self-reflection.' The intervening conditions that facilitate action/interaction strategies were 'attitudes of husbands,' 'mutual awareness of couple,' 'health status,' and 'support systems.' The consequences were 'readaptation of marital relationships,' and 'unresolved conflicts,' and 'trying alone.' This research classified middle-aged and elderly couples' adaptation into three types such as mutual effort, separation & resignation, and conflicts vestige. The findings provide basic information to develop a retirement adaptation program for the middle-aged and elderly.

The purpose of this study was to understand the subjective breastfeeding experience of primiparous women to identify how breastfeeding was started and to explore the process of breastfeeding. The Grounded theory methodology was used. Data was collected from 6 primiparous women who had breastfed their infants for at least over 8weeks, recently breastfeeding or having breatfed their infants within the last 6 months. With the permission of the subjects, the interviews were recorded and transcribed. The data were analysed in the framework of grounded theory method as mapped out by Strauss and Corbin(1990). 105 concepts and 21 subcategories were confirmed in the analysis. In the process of data analysis, "Identity as a mother" was found to be the core phenomenon. The 21 sub-categories were as follows : natural food, neighbour inducement, self purpose, good feeling, tenderness, breast pain, change of breast shape, physical discomfort, loss of physical energy, confirmation of maternal role, formation of affection feeling of adhesion, one body through coupling, tie, capacity, role performance, mental comfort, healthy mother, healthy infant, confidence of breast milk, feeling of satisfaction. The sub -categories were again grouped into 14 categories including infant nutritious food, formation of breastfeeding opportunity, feeling of satisfaction, injury of the breast, physical suffering, awareness of mothering, formation of maternal affection, connecting, coupling, acceptance, effort, emotional stability, mother and child health and feeling of achievement.hievement.

This study is intended to examine the modernization of Chinese costumes through historical events, and to analyze the characteristics of the costume modernization process. The modernization of Chinese costumes appears to have begun with the Opium Wars, and the Nanjing Treaty(1842), the Beijing Treaty(1860) and the official residence of western people in Chinese territory. Afterwards, in order to initiate change, the Chinese people themselves implemented the Westernization movement(1861-94), placing an emphasis on the westernization of external elements such as technology and form, but aspects such as costume, deeply saturated in their traditions, do not appear to have changed significantly. Despite self-empowering movements such as these, as western forces diffused deeper into the Chinese mainland, neo-intellectuals formed the axis of a revolutionary movement. A major example can be found in the Xinhai Revolution(1911) revolution, which forbade the binding of feet and shaving of frontal hair and partially implemented western formal dress. Through these factors, the modernization process of Chinese costume demonstrates characteristics of an adherence to traditional dress and partial acceptance of western attire. Through this, we may understand the modern costumes of China, which adhered more to tradition than Japan, which pursued western costumes actively within a similar period, and Korea, which rushed modernization due to Japanese authority.

The characteristics of health behavior related pregnancy and childbirth have reflected on the cultural belief and value in the society. The efforts for women's health promotion through the current illumination of the traditional health care are the prompting assignment to be in nursing. The process of motherhood already progress before the motherhood actually. The functional state as the expectant mother can be the important predicting factor of the postpartum state, the quality of a married life. Motherhood was analyzed by Walker and Avant's method to clarify the concept 'to be a mother' using the various concepts like Koreans' Taekyo, transition to motherhood, maternal identity, maternal role attainment, maternal fetal attachment, and maternal fetal interaction. Upon the concept analysis, naturalness, responsibility, attachment, readiness, controllability were identified as the defining characteristics of motherhood. The antecedents of motherhood were consist of maternal affection, positive self esteem, pregnancy acceptance, fetus recognition and the consequences of motherhood were consist of positive maternal identity, maternal fetal attachment, confidence about the maternal role, the healthy mother and the healthy baby. The empirical referents of motherhood were consists of recognition of motherhood, expectation about motherhood, fetal recognition with ultrasonography and fetal movement, experience of unification between mother and fetus, expression of affection to the fetus, concern about fetal health, concern and practice about Taekyo, adaptation behavior about physical change and discomfort due to pregnancy. Therefore it is necessary to develop the instruction program of motherhood including the defining attributes identified in this study.

Purpose: This study was done to identify and compare factors associated with intention to receive Human Papillomavirus (HPV) vaccine between male and female undergraduate students. Methods: In the fall of 2010, 479 students responded to self-administered questionnaires about their intention to receive HPV vaccine, HPV knowledges, HPV related involvements and optimistic bias, subject's characteristics including opinion about HPV vaccine. Mann-Whitney U test, uni-variate and multi-variate logistic regression were used for data analysis with SPSS/WIN. Results: Intention to receive vaccine were 22.0% of men and 25.0% of women. There were significantly different in HPV knowledge (Z=-2.74, p=.006), optimistic bias (Z=-4.60, p<.001), vaccine is necessary for women (Z=-4,30, p<.001), vaccine is necessary for men (Z=-4.37, p<.001), vaccine is necessary if only symptom exist (Z=-4.52, p<.001), but there were not different in intention to receive vaccine, involvement between men and women. Concern about vaccine safety (OR=3.19, 95% CI 1.63~6.23) was determinant of intention to receive HPV vaccine for men. Conclusion: This study showed gender differences in HPV knowledge, HPV related optimistic bias and opinion about HPV vaccine, which would be assessed and well managed in tailored HPV education for enhancing HPV vaccine acceptance.
