The purpose of this study was to find out differences between nursing teachers and non-nursing teachers in sex education, to offer the degree of conducting sex education and teachers' perceptions of teaching ability The subjects were 291 middle and high school teachers in Busan from June 25 to July 22, 2002. The results of this study are as follows. 1. According to the survey of 22 items relating to the degree of conducting sex education, the average of nursing teachers(2.87) was higher than that of non-nursing teachers(2.69). This finding showed that there was a significant difference between both groups(p<.05). 2. According to the survey of 22 items relating to teaching abilities, the average of nursing teachers(2.88) was higher than that of non-nursing teachers(2.63). There was also a significant difference between both groups(p<.01). According to the results of the study, I make the following suggestions. 1. Sex education should be adopted as a regular course and conducted as a school health program in regular curriculum. 2. Compared with non-nursing teachers, nursing teachers conducted sex education frequently and efficiently and their perception of sex education was higher. Therefore, the school policy which requires that sex education should be conducted by nursing teachers only is to be established.

Purpose: The purpose of this study was to identify the mediating effect of head nurses' emotional leadership as perceived by nurses in the relationship between nurses' job stress and job satisfaction. Methods: Study participants were 278 staff nurses currently working at two university hospitals in Busan, Korea. SPSS/WIN 21.0 program was used for data analysis to analyze descriptive statistics, t-test, correlation, and stepwise multiple regression. The significance level was set at p<.05. Results: Nurses' job satisfaction had a significant correlation with job stress (r=-.31, p<.001) and emotional leadership of nurse managers as perceived by nurses (r=.53, p<.001). Also, head nurses' emotional leadership experienced by nurses had a partial mediating effect in the relationship between nurses' job stress and job satisfaction. Conclusion: The results of this study show that the nurse managers' emotional leadership has an important influence on nurses' job stress and job satisfaction. Therefore, head nurses' emotional leadership is very important for effective human resource management and the hospital should offer education and training to booster head nurses' leadership by developing emotional intelligence to promote staff job satisfaction.

This is a follow-up study to "An Analysis of the Fitting of Plus-sized Women's Formal Jackets in On-line Shopping Malls", in which we compiled basic sizes of formal jackets sold in online retailers for plus-sized women and compared specific measurements of the jackets from each retailer. Emphasizing a comparison of age groups 20-39 and 40-59, fit evaluations and analyses were conducted in order to provide data to help manufacturers develop formal jacket patterns that reflect physical characteristics of plus-sized consumers and offer better physical fit. The surveys and evaluations were conducted between October 2007 and May 2008. and the compiled data were analyzed using the SPSS 17.0 statistics program. The results were summarized as follows. The two age groups gave different evaluations of the fit problems in the women's formal jackets sold in online retailers. Whereas the age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas, the age group 40-59 said that they found more problems in the armscye, upper arms, sleeve length and jacket length. Modifying the shoulder area, armscye depth and jacket length severely compromises the jacket's balance, and attention to these areas must be given during pattern design.

Purpose: The purpose of this study was to identify the factors affecting sleeping patterns among hospitalized elderly. Methods: A descriptive correlational study was conducted. Participants were 121 hospitalized elderly in a hospital located in a county. A structured questionnaire was used for data collection. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and stepwise multiple regression. Results: Almost a half of hospitalized elderly in this study suffer from sleep disturbances. As results of univariate analyses, physical symptoms, anxiety, depression, and environmental factors disturbed sleep among hospitalized elderly. However, the result of stepwise multiple regression analysis identified that anxiety and environmental factors were significant predictors of sleeping patterns for hospitalized elderly and these two factors accounted 32.5% of variance of sleeping patterns among hospitalized elderly. Conclusion: Sleep assessment should be conducted on admission to identify sleep difficulties and thereby to improve quality of nursing care. Nurses and other health care personnels should make efforts to decrease anxiety and to eliminate environmental barriers of sleep among hospitalized elderly. Educational programs for nursing staff that offer information about sleep and sleep promoting interventions for the elderly patients are critical. Moreover, sleep promotion intervention program should be developed, applied and evaluated.

Automatic train control systems are divided into ATC, ATP and ATS systems etc. The ATP and ATS systems offer discontinuous information for train control. While the ATC systems provide continueous information for train control. There is a method for offering continuous information by AF track circuits. Magnetic fields are formed by current through rails in the AF track circuit systems. So, the continuous information is received by the magnetic fields on a on-board antenna. Coating materials on rails are researched to decrease defects such as head check, shelling, corrugation, squats and so on in Germany. Currently, a coating method of rail construction is proposed by using the ceramics in Korea. When deciding physical characteristic of ceramics, researches are required about variation of flux density by the ceramics. In case that the flux density is much lower than existing value, the information for train control is not transmitted to the on-board antenna. In this paper, inductance on rails is calculated and a model is presented about variation of the magnetic field intensity in the AF track circuit. Standard permeability of ceramics is proposed by analyzing the variation of magnetic field intensity. It is demonstrated by using Maxwell and Matlab program.
