본 연구의 목적은 건강보험 지역가입자의 부담능력별로 수직적 형평성을 측정하고, 시간의 변화에 따라 각 부담 능력이 보험료의 변화와 인과관계를 보이는지 종단분석하는 것이다. 분석대상은 한국복지패널 6차~10차에서 추출된, 2011-2015년에 실시된 조사에 모두 참여한 지역가입자 가구주 749명이다. 분석방법은 카크와니(Kakwani) 누적지수 산출과 패널회귀분석의 고정효과 모형이다. 연구결과로는 첫째, 지역가입자의 종합소득에 대한 보험료부과가 소득분위, 연도별로 가장 누진적이다. 둘째, 패널회귀분석 결과 지역가입자의 종합소득이 보험료 변화를 설명하는데 유효하지 않아, 종합소득에 대한 보험료부과가 형평성을 저해하지 않는 것으로 나타났다. 순재산과 소비지출, 가구주의 연령, 가구원 수는 보험료에 통계상 양(+)의 유의미한 영향을 미치고 있는 것으로 나타났다. 주요결과에 따라 정책적 제언을 논의하였다.
The aim of this research is to identify the validity and reliailbity of Self-Efficacy for Exercise Scale (SEE) fo r older adults (Resnick & Jenkins, 2000). The datao f 134 elderly women (75±4.6yr) were statistically analyze d using exploratory factor analysis to test the structure of the scale and t-test for the difference between exercise & non-exercise group. Pearson correlation of the SEE to Bandur a(1997)'s Exercise Self-Efficacy(ESE) was examined as the approach to concurrent validity. As results, multidimensionality of the structure of SEE was not proved; rather one factor model was sustained. The self-efficayc of the exercise group was significantly hig h and it provided evidence of construct validity. Correlation bewteen the SEE scale and Bandura (1997)'s scal e was high and coefficient alpha (.91) was adequate for the intenral consistency. In conclusion, the SEE scale i s shown to be an appropriate measure of exercise self-efficacy for older adults.
Purpose: The purpose of this study is to validate self-perceived Fall Efficacy Scale and Activity-specific Balance Confidence scale comparing with the performance based measurement for fall related physical factor. Method: The data were obtained from 70 elderly women who participate din both self-perceived test and performance based measurement. Korean version of Efficacy Scale and Activity-specific Balance Confidence scale and the performance based measurement such as static banl ce, static balance of one leg both open and close eyes, gait speed, raising from a chair 5 times, ando ging up & down 4 stairs were tested. Collecte d data were analysed using correlation, t-test, sensitivity and specificity. In addition, average Z score for the performance based test was calculated in order to compare these Z scores with self-perceived test. Results: The results of this study are as follows. 1) The self-perceived test showed moderate criterion validity. 2) It is able to categorizing elderly according to the their measured physical performance level. 3) The selfperceived test showed moderate sensitivity. Conclusion: In summary, the self-perceive test is a simple and moderate valid instrument, and can be used as alternative for fall related physical assessment in elderly.
The external feature and position of compound eye of 10 species belong to 6 families in Korean Neuroptera were studied with a image analyser. The results were as follows: 1. Three groups(Corydalidae and Inocelliidae; Chrysopidae, Mantispidae, and Myrmeleontidae; Ascalaphidae) were classified according to similarities in external feature and position of compound eye. It agrees with a classification system by Richards & Davies. 2. The compound eye in Ascalaphidae is divided into the upper and lower part. And the diameter of a facet of the upper part was longer than that of the lower part.
The purpose of this study was to verify differences in postural stability between the obese and normal weight female adults during quiet standing on force platform(normal surface) and narrow beam(narrow surface) with two legs and left leg. For measuring postural stability, the percentage of uncompleted trials and the area of center of pressure(COP) displacement were calculated. Analyses of data revealed that 1) Postural stability decreased as support-surface is narrowing. 2) The percentage of uncompleted trials of the obese was significantly higher as compared that of the normal weight. 3) The area of COP of the obese was significantly wider as compared that of the normal weight. Therefore, these results suggested that the obese have poor ability of postural stability.
The purpose of this study was to test differences in postural stability and strategies of postural control between the obese and normal weight female adults during quiet standing on force platform(normal surface) and narrow beam(narrow surface) with two legs and left leg. The peak amplitude and the peak frequency of center of pressure(COP_y and COP_x) displacement were calculated by the frequency components analysis(FFT). Analyses of data revealed that 1) The peak amplitude of COP_y and COP_x increased as support-surface is narrowing. 2) The peak amplitude of COP_x of the obese was significantly larger as compared that of the normal weight. 3) The peak frequency of COP_y and COP_x increased as the difficulty of task is higher. 4) There were not significant differences in the peak frequency of COP_y and COP_x between the obese and the normal weight. Therefore, these results suggested that the obese have poor ability of medial-lateral postural stability and that the number of oscillation increase in order to enhance the movement adaptability in performing a difficult task.
The purpose of this study was to investigate the effects of the duration of Taekwondo training and gender on mood states in elementary school students. The 144 long-term trainees participating in Taekwondo training program over 2 years, 100 mid-term trainees, and 128 novices(19 non-participants and 109 students participating in it below 6 months) responded to the Korean version of the Profile of Mood States(K-POMS). The analysis of data revealed the following results. 1. The long-term trainees had the lowest score than mid-term trainees and novices in the total negative mood states and all 5 sub-factors of negative mood states(tension-anxiety, depression-dejection, anger-hostility, fatigue-inertia, and confusion-bewilderment). However, there were no significant deferences in it among groups.2. There was significant deference in the score of the total negative mood states and 4 sub-factors of negative mood states(tension-anxiety, depression-dejection, anger-hostility, and fatigue-inertia) between male and female. Male presented a positive mood states than female.
