  • The purpose of this study was to compare the differences in kinematic variables and grip forces among professionals(PG), amateurs(AG), and novice group(NG) during golf putting. The participants consisted of 3 groups based on their playing ability: 8 professional golfers (handicap<5), 8 amateurs (handicap<18) and 8 novice. Each subject attempted 2.1m putts from the hole. 3D motion analysis system(Motion analysis Corp., USA) with 6 high speed cameras and grip force measurement system(Kim et al., 2007) were used to acquired kinematic and force data, respectively. To compare differences among groups, joint angles of upper limbs, trajectory and smoothness by jerk cost function(JC) of putter head and grip forces were used in this study. Results showed that there were significant differences among groups in most of variables such as joint angles, trajectory & smoothness of putter head, and distribution of grip force in both hands. In brief, we confirmed that putting stroke in PG was more accurate and smooth than that in other groups, especially NG, due to their well-controlled upper limbs and keeping grip forces constant in both hands. It can be concluded that due to skilled levels, fundamental differences of putting movement could be identified and these differences might be helpful for improving one's putting skills.

  • The purpose of this study were two fold : first, to determine the effect of aerobic exercise on BP, pulse rate, body fat, body weight, symptoms of sterss response: and secondly, to apply the aerobic exercise on nursing practice in the healthy or ill subjects. In an attempt to investigate the physiological and psychological effect of exercise, a quasi -experiment, non-equivalent control group pre-test & post-test design was planned. Experiments were carried out from July 4, through August 30, 1994 with 37 subjects conveniently sampled from K & Y sports center located in Taejon. The 37 research subjects were assigned to experimental(16 subjects) and control(21 subjects) groups. Aerobic exercise was carried out for experimental group from three times to five times a week for 6 weeks in aerobic center. Data were analyzed with t-test, mean, per centage of change using SAS program. Results were obtained as follows: 1) Systolic blood pressure (M=123.75mmHg, % of change=1.12%) and diastolic blood pressure (M=74.38mmHg, % of change=5.79%) was increased on that of experimental group after 6 weeks experiment. But there was no significant difference between experimental group and control group. 2) Body weight was decreased on that of experimental group(M=56.54Kg, % of change=-1.60%) and that of control group(M=52.05, % of change=-0.99%) after 6 weeks. But there was no significant difference between experimental group and control group. 3) Body fat was decreased on that of experimental group(M=30.53%, % of change=-3.60%) and that of control group (M=28.75%, % of change=-3.52%) after 6 weeks. There was no significant difference between experimental group and control group. 4) Pulse rate was decreased on that of experimental group(M=69.19회/min, % of change -8.43%) and that of control group(M=76.0회/min, % change -0.07%) after 6weeks. There was significant difference(t=-2.621, P<0.05) between experimental group and control group. 5) Symptoms of stress response were decreased on that of experimental group(M=0.97) and that of control group(M=1.15) after 6 weeks. There was no significant difference between experimental group and control group. Therefore, adherence to aerobic exercise for 6 week seem to be affected mainly pulse rate of subjects. A futher study is necessary to determine the difference in the effect of variety exercise, programs, to study over 6 weeks, to produce professional educational program for exercise speciality nurses.

  • The purpose of this study was to identify the relationship between self-empowerment and a health promoting lifestyle in climacteric women, and to provide the basic data for health promoting intervention. The subjects were 246 women who visited the sports center in Taegu, Korea and ranged in age from 40 to 59. The data was collected during the period from December 2nd to December 15th, 2001. The instruments were the revised health promoting lifestyle scale developed by Park, In Suk(1997) Originally the instruments were developed by Spreitzer(1995) and Jung Hea Joo(1998), who translated it into Korean. The data was analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. The results of this study were as follows : 1. Mean score of total empowerment was 3.76 and the subcategory 'meaning', had the highest score at 4.08. 2.Mean score of total health promoting lifestyle was 2.83 and in the subcategory, the highest degree of performance was 'sanitary life', followed by 'harmonious relationships' and 'self actualization'. The lowest degree was 'professional health management'. 3. A significant statistical difference between age, education and self-empowerment was found. 4. A significant statistical difference between age, marital status, leisure time activity (hobbies/community service) and a health promoting lifestyle was found. 5. Health promoting lifestyle was positively related to self-empowerment(r=.4592). A health promoting lifestyle was the highest positively related to the subcategory 'impact' (r=.4329). 6. The most important variable affecting the health promoting life style was impact which accounted for 19% of the total variance in stepwise multiple regression analysed. Five variables, impact, age, meaning, marital status and leisure time activity(hobbies/community service) accounted for 26% in promoting a healthy life style. From the results of the study, the following recommendations are presented : 1) Adopting the concept of self-empowerment is required in broad nursing fields. 2) Using and making a self-empowerment promoting program which can cause positive effects on a health promoting lifestyle are required. 3) It is required to check the rank of the subcategories such as meaning, competence, self determination and impact according to the subjects. 4) It is required to check the effects of all variances of self-empowerment, self-efficacy and self-esteem variances through the repeated studies.

  • This research was designed to find out what is a distictive feature of the design elements of Korean women's costume and its influence by analizing the trend of Korean women's constume during the period of 1890 and 1995. The research was analized by a total of 854 random samples of clothing styles collected from materials in the museums and from articles of three leading newspapers and one of the best women's magazines in Korea. The changing trend of Korean women's costume was found out to be as follows: 1. In around 1910s, the trend of Korean women's costume has been changed into two-tier structure of both Korean and Western styles, and the typical and traditional Korean women's street wears such as 'Chang-ot' and 'Tsdechima' have been gradually diminished. 2. From 1920s, length of the Korean skirt, which was unnecessarily long and inconvenient, has been getting shorter for the convenience of walking. In addition, Korean women's underwear has become simplified, and sports wear could be seen for the first time in Korea. 3. During 1960s, the Western clothing styles have been increased rather than Korean styles as the street wear of the Korean women. 4. In 1970s, blue jeans, mini-skirts and casual wears have become a trend or fashion for women in Korea. 5. In 1980s, a fashion of unisex mode has arrived in this country, and from the year of 1987, wearing of panties among the Korean women has been increased rather than skirts wearing for the street wear. 6. During 1990s, various forma of complex styles came into being in such styles as so-called 'orange class style,' 'protruding navel T-shirts' and 'runner wear speedy.' From mid-1990s, Korean women have turned out to prefer the cute and light costumes by placing emphasis on the image of intellectual, professional and functional wears. The changing special feature of the Korean women's clothing designs could be distinctively observed during 1960s as the modernization policies in Korea have been processed during the period. The clothing trend before 1960 was to change and to solve problems of inconvenient and impractical wears, but the trend after 1960 was seen as a change to confirm a trend of the world fashion. From mid-1990s, however, preference of Korean women's self-conceited conception socially and an unquestionable changing pattern of Korean women's life.
