Purpose: The purpose of this study was to investigate factors affecting health promoting lifestyle in nursing students. Methods: A descriptive cross-sectional study was done using a convenient sampling (n=682) in a three-year nursing college. The health promoting lifestyle was measured by the instrument of Walker's and self esteem was measured by the instrument of Rosenberg's. Data were analyzed by descriptive statistics, chi-square test, oneway ANOVA and Stepwise multiple regression. Results: The average score of health promoting lifestyle was 2.34. The score of psycho-social well-being subscale was higher than that of health promoting behavior subscale. The highest score was on the interpersonal relations subscale, and the lowest score was on the physical activity subscale. The self-esteem, mental health status, satisfaction with school life, school year, perceived economic status, and gender accounted for 31.9% of the variance of health promoting lifestyle. Conclusion: Self-esteem was the most powerful influencing variable of the health promoting lifestyle, and physical activity was the lowest score of the health promoting lifestyle subscale. Therefor nursing educators should consider to include a health promotion program with increasing self esteem and physical activity in the nursing curriculum.

The study attempted to explore the dimensionality of mother's psychological well-being. The major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing mother's psychological well-being. Instrument for assessing psychological well-being was developed with 9 variables(sense of control, sense of achievement, sense of confidence, sense of acceptance, sense of intimacy, sense of assistance, sense of immersion, sense of hope, and sense of satisfacion) in 3 dimensions(sense of competency, sense of relation, and sense of improvement) with 4 rating scales of 102 items. After the scale development, the estimates of reliability for the 9-variable scales were Cronbach's ${\alpha}=.71{\sim}.90.$ The correlation between the two scales, Psychological Well-Being Index(Franklin, 1996) and Psychological Well-Being(Ryff & Keyes, 1995) was .21~25. The subjects were divided two groups by the score of the Mother's sense of Psychological Well-Being. And the group has hiher score in Mother's sense of Psychological Well-Being showed the higer score of Perceptions of Parental Role Responsibilities Scale(t=3.24, p=.002).

In situ particle size and volume concentration of suspended sediment was measured at the mouth of Seomjin River Estuary In February 2001, using an optical instrument, 'LISST-100'. Time variation of in situ particle size and concentration shows: (1) during ebb tide, Seomjin River supplies relatively fine-grained particles with less-fluctuated, compared to during flood tide, and well-behaved concentrations following the tidal cycle; and (2) during flood tide, relatively coarse-grained particles with highly variable in size distribution and concentration flow upstream from Kwangyang Bay. This explains a poor correlation $(r^{2}=0.10)$ between sediment concentration and beam attenuation coefficient during flood and a high degree of correlation $(r^{2}=0.80)$ during ebb tide. Relatively fine grained and well defined, monotonous size distribution may promote the correlation between concentration and beam attenuation coefficient due to optical homogeneity of particles during ebb tide. Abundance of large aggregates with time-varying size and shape distributions may be mainly responsible for variations in optical properties of the sediment during flood tide, and thus may confound the relationship between the two variables. The difference in particle sizes and shapes between flood and ebb tides can also be observed on SEM images.

본 연구의 목적은 국가복지가 확대되는 우리 현실에서, 복지국가의 발전방식(제도 보편성)에 대한 선호에 영향을 미치는 요인이 무엇인지를 파악하는 것이다. 특히, 주관적 인식과 선호의 인과구조를 밝히는 과정에서 발생할 수 있는 내생성(endogeneity) 문제를 고려해, 도구변수를 활용한 2SLS 회귀분석을 시도하였다. 분석결과는 다음과 같다. 첫째, 국가복지의 확대에 반대할 것으로 예상되는 집단(고소득자, 저위험자, 그리고 고용주/자영업자 등)들이 보편적 복지는 선호하는 것으로 나타났다. 둘째, 주관적 인식의 경우 복지제도 및 수혜자에 대한 부정적 인식은 보편적 복지를 반대하는 쪽으로 영향을 미쳤다. 추가로 부정적 인식은 산업화 시대를 오래 경험한 세대들에서 더 강한 것으로 나타났다. 셋째, 태도로 태도를 설명하고자 할 경우에 발생할 수 있는 내생성 문제가 본 연구에서도 확인되었다. 이것은 실제로 추정회귀계수를 왜곡시키고 있었다. 따라서 관련 후속연구들은 분석과정에서 이를 유념해야 할 것으로 보인다.

Purpose: The purpose of this study was to discover kidney transplant and hemodialysis patients' quality of life(QOL) and provide basic data to improve their QOL. Method: One hundred two hemodialysis patients and 106 kidney transplant patients were given a self-administered questionnaire from Mar. 6 to Mar 31, 2006. The instrument consisted of demographic variables, therapeutic-related characteristics and QOL. Collected data was processed using the SPSS 12.0 statistical program for real numbers, percentages, ANCOVA, t-test, ANOVA, Stepwise multiple regression and the Scheffe test. Results: Kidney transplantpatients' QOL was higher than hemodialysis patients. The demographic variables which showed a significant difference in overall QOL were religion, children and monthly income for kidney transplantpatients and educational background for hemodialysis patients. The therapeutic-related variable which showed a significant difference in overall QOL was the patients' perceived health condition for both groups. The influencing factor on overall QOL for both groups was the health condition perceived by themselves. The total variance of the variable for QOL was 42% for kidney transplant patients and 19% for hemodialysis patients. Conclusion: This study revealed that kidney transplant patients have a higher QOL and how patients perceive their health is the strongest influencing factor for QOL. However, there is a large difference between the demand and supply of kidney donors. To solve this problem the standards for donation should be reviewed and revised.
