방용주 ( Bang Yong Ju ) 한국병원경영학회 2003 병원경영학회지 Vol.8 No.3
The purpose of this study was to analyze the Characteristics of socio-demographic, organizational conflict and job satisfaction, and to examine the interrelation of influential factors in the intention of turnover. The data for this study were collected through a self-administrated survey with a structured questionnaire to 1,027 subjects from several medical doctor staff members, nursing- staff members, administration staff members, pharmacist, and technical expert of eleven hospitals. The data were collected by self-reporting questionnaire from July 29 to September 7, 2002. In t h s analysis frequency test, t-test, ANOVA, multiple regression were used. The main results of this research is as following; 1. According to socio-demographic characteristics of the respondent s level of the intention of turnover was higher in a doctor staff members than others, for females than males, and had worked for 5-10 years in hospitals. Also, the intent to turnover was generally higher younger workers than long terms workers. 2. According to the organizational conflict characteristics as the respondents who got less conflict experience in the organization, their level of the intention of turnover was higher. And, technical conflict experiences were expressed greater than hierarchical conflict experiences. 3. According to the job satisfaction characteristics as his or her satisfaction that is about the promotion, working itself, salary, and fellowship in the organizational was higher, the level of the intention of turnover was lower. 4. Accordmg to the result of Multiple Regression for the doctor staff members in general hospitals rather than special hospitals was negatively correlated with the satisfaction of working itself while hierarchical conflict factors in the organizational conflict characteristics was positively correlated with the intention of turnover. For the nursing staff members the job satisfaction for the working itself, salary were negatively correlated with the intention of turnover. For the administration staff members as the job satisfaction for the working itself was negatively correlated with the intention of turnover. For medical and pharmacy staff members as more working experience, correlation with the intention of turnover was negative. Besides, as the job satisfaction for the working itself and the fellowship was negatively correlated with the intention of turnover. For the skill and technicians, the job satisfaction for the working itself, promotion were negatively correlated with the intention of turnover. The above indicate that job satisfaction and promote their ability and form a good relationship with organization members were very important to decrease the intention of turnover. This study identified the major effective factors of the intention of turnover and analyzed the differences among the job category. In that respect, it is significant for the study to be able to provide a reference for managing hospital of industrial accident and organizational development. However, this study has a problem, which is not to identify a valuable model for examining the relationship between organizational factors such as organizational conflict, job satisfaction, and intention of turnover. Therefore, further study is needed and strengthened in the field of intention of turnover for hospital for industrial accident.

Various La-based perovskite catalysts were prepared by a Pechini method, and they were applied to the low-temperature oxidation of odor compounds exhausted from waste food treatment process for effective deodorization. Quantitative and qualitative analyses of exhausted gas were conducted to measure the amount of major odor compounds with respect to operation time. A standard odor sample composed of major odor compounds was then prepared for use as a feed for oxidation reaction system. Various transition metal(M)-substituted La-based perovskite catalysts (LaMO3: M=Cr, Mn, Fe, Co, and Ni) were prepared and applied to the oxidation of odor compounds in order to investigate the effect of transition metal M. Among the catalysts tested, LaNiO3 catalyst showed the best catalytic performance. Pt-substituted perovskite catalysts (LaNi1-xPt03: x=0, 0.03, 0.1, and 0.3) were then prepared for enhancing the catalytic performance. It was found that LaNi0.9Pt0.1O3 catalyst served as the most efficient catalyst. Supported perovskite catalysts (XLaNi0.9Pt0.1O3/Al2O3: X=perovskite content(wt%), 0, 10, 20, 30, 40, 50, and 100) were finally applied for the purpose of maximizing the catalytic performance of perovskite catalyst in the low-temperature oxidation reaction. Catalytic performance of XLaNi0.9Pt0.lO3/Al2O3 catalysts showed a volcano-shaped curve with respect to perovskite content. Among the catalysts tested, 20LaNi0.9Pt0.1O3/A12O3 catalyst exhibited the highest conversion of odor compounds of 88.7% at 180℃.
