Objective: The aim of this study was to provide a method to improve the compliance and reduce the time by reducing the workload during the model change work. Background: The enterprises are constructing the small quantity batch production system by increasing the number of model change and reducing model-changing. However, the compliance is low because the work is strenuous and high skills are needed, so the system management is facing with many difficulties. Method: After classifying the model change work according to the purposes(preparation, change and adjustment) with the target of mascara filling machine, element tasks time were measured and the motion analysis(therblig symbol) and REBA analysis were performed. The study incorporated 3 independent variables as the number of motion, REBA score and the element time. The dependent variable is the type of element work as preparation, change and adjustment. The statistical test was performed by one-way ANOVA(${\alpha}$ < 0.05). Results: For the preparation, the number of motions appeared in the order of Use(U), Transport Loaded(TL), and Position(P). The order appeared in change is Use(U), Release Load(RL), and Grasp (G). The adjustment appeared in the order of Position(P) and Use(U). The results of average motion time as the element work times divided by the number of motion appeared in the order of adjustment(1.85sec/motion), preparation(1.11sec/motion), and change(0.62sec/motion). The results of REBA showed that the average risk level of change and adjustment were medium, but 53.1% of change and 42.9% of adjustment were evaluated as high. Conclusion: Reducing the avoidance and improving the compliance of work could be expected if the job autonomy were improved by improving the working postures with high risk level. Application: It is expected to solve the problem of reducing the time of model change work in the small quantity batch production system. The future work is to carry out the improvement directions found in the results and compare the results after improvement.

Purpose: This study was to investigate the degree of postpartum depression and its predictors at six months postpartum. Methods: The subjects were 161 women six months after delivery who were registered with the public health center. The instruments included a survey of various characteristics, the Edinburgh Postnatal Depression Scale(EPDS), husband support, maternal self-esteem, and marital adjustment scale. The data was analyzed using the $x^2$-test, t-test, the Pearson correlation coefficients, and the logistic regression. Results: The point prevalence of postpartum depression at six months postpartum was 14.3%, corresponding to a score of 12 or higher on the EPDS. Postpartum depression was significantly associated with husband support, maternal self-esteem, and marital adjustment. Predictors of postpartum depression identified by the logistic regression analysis include marital adjustment (OR .29 [95% CI .13-.61]) and the delivery method(OR 3.57 [95% CI 1.25-10.23]). Conclusion: Strategies for improving postpartum depression, considerations of husband support and maternal self-esteem are important in research and practice. In addition, interventions for reducing Cesarean delivery and improving marital adjustment are needed.

This study is to analyze the efficiency of Korean fishing ports using DEA. First, the study calculated the efficiency scores based on a CCR-BCC framework and hence technical, pure technical, and scale efficiency scores are seperated for the 38 fishing ports under study. The Average of technical, pure technical, and scale efficiency are turned out to be 0.6834, 0.8582, and 0.7774 respectively. The 15 fishing ports are fully efficient under the constant returns to scale while 21 fishing ports under the variable returns to scale. Second, the super efficiency scores are also calculated under the radial model without the consideration of slacks. The highest score is turned out to be 4.4984 for the P16 fishing port with the average score of 0.9652 for the entire fishing ports. Nevertheless, P16 fishing port has showed up only once as a reference set. On the other hand, P34 fishing port has showed up 11 times as a reference set, which scored the second highest score of 2.9815. Finally the super efficiency scores are calculated under the non-radial model with the explicit consideration of slacks. Now the P34 fishing port scored the highest score of 2.3424 with even 15 times referred to a bench-mark. Therefore the importance of P34 fishing port is emphasized once again on the field of bench-marking for the efficiency of fishing ports. When the targets for the input factors to improve the efficiency of each DMU are calculated the area of fishing port needs the most adjustment to be reduced for 40.36% on the average, while the cosignment sales area does the least adjustment for 13.70%.

This descriptive correlational study was carried to identify the relationship among social support, compliance, and psychosocial adjustment of patients with rheumatoid arthritis. The study was done with 100 rheumatoid arthritic patients who were visited in Outpatient clinic of university hospital in Taegu, Korea from the 23rd of February to the 20th of March in 1998. The Data were collected through person to person interviews which were performed by five researchers. The instruments used for this study were Yu's social support scale(1996), Cho's compliance scale(1987), and Kim's psychosocial adjustment scale(1997). The data was analyzed by using a t-test, Pearson correlation coefficient, ANOVA, and Tukey test with the SAS Program. The results of this study were as follows ; 1. The mean score of social support was 2.76 for 4 full marks, compliance was 3.20 for 5 full marks, and psychosocial adjustment was 2.26 for 4 full marks. 2. Hypothesis 1 : "The higher the social support degree, the higher the compliance degree of the rheumatoid arthritis patient". It was supported(r=0.54, p<0.001). Hypothesis 2 : "The higher the compliance degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.34, p<0.001). Hypothesis 3 : "The higher the social support degree, the higher the psychosocial adjustment degree of the rheumatoid arthritis patient". It was supported(r=0.24, p<0.05). 3. In general, the spouse group compared to other groups was demonstrated as the most dependable group for patients to trust and expect support. And the sons and daughters group was shown higher than other groups in terms of social support(F=4.19, p=0.01). There was no difference in terms of compliance in degree. In the degree of psychosocial adjustment the highly educated group(more than high school) is a little higher than the lowly educated group(F=3.08, p=0.03). In the costs of medical care, the group that could afford was significant higher than the group which could not afford results in terms of the psychosocial adjustment degree(F=3.99, p=0.01). The outcome of this study is that the social support that related rheumatoid arthritic patients had an effect on the following compliance, and the following compliance helps psychosocial adjustment of patients. It also shows that social support related psychosocial adjustment. Therefore, to increase the level of psychosocial adjustment of rheumatoid arthritic patients, it will be effective in supportive nursing intervention to improve social support and compliance.

This study examine the firms fund R&D expenditures through cash and cash equivalents under financial distress in order to avoid huge adjustment costs that can be brought after R&D expenditures cut-down. Other study divided the firms' financial condition by only firms' year. This study identifies the firms' financial condition not only by a firm's year but also by firm size and Altman's Z-Score and K-Score. The results show that there are statistically negative relationship between R&D expenditures and cash and cash equivalents when firms are under financial distress. The results are same regardless of criteria of classification of firms' financial condition, which is consistent to the hypothesis. Young and small firms and firms with moderate possibility of bankruptcy fund R&D expenditures through cash and cash equivalent compared to the other firms. We can find the new evidence when we classify the firm by Z-Score and K-Score of Altman. The firms with high possibility of bankruptcy can not fund for R&D activities from cash, but only the firms with moderate possibility of bankruptcy fund R&D expenditures through cash and cash equivalent in the condition of financial distress. The evidence suggests that firms fund R&D expenditures by cash and cash equivalent when they are under financial distress. Findings provide an implication on the management of R&D expenditures and liquidity in the firms.

Background : Among 'structure', 'process' and 'outcome' approaches, outcome evaluation is considered as the most direct and best approach to assess the quality of health care providers. Risk-adjustment is an essential method to compare outcome across providers. This study has aims to judge performance of hospitals by severity adjusted mortality rates of coronary artery bypass graft (CABG) surgery. Methods : Medical records of 584 patients who got the CABG surgery in 6 general hospitals during 1996 and 1997 were reviewed by trained nurses. The MedisGroups was used to quantify severity of patients. The predictive probability of death was calculated for each patient in the sample from a multivariate logistic regression model including the severity score, age and sex. For evaluation of hospital performance, we calculated ratio of observed number to expected number of deaths and z score [(observed number of deaths - expected number of deaths)/square root of the variance in the number of deaths], and compared observed mortality rate with confidence interval of adjusted mortality rate for each hospital. Results : The overall in-hospital mortality was 7.0%, ranged from 2.7% to 15.7% by hospital. After severity adjustment the mortality by hospital was from 2.7% to 10.7%. One hospital with poor performance was distinctly divided from others with good performance. Conclusion : In conclusion, severity-adjusted mortality rate of CABG surgery might be applied as an indicator for hospital performance evaluation in Korea. But more pilot studies and improvement of methodologies has to be done to use it as quality indicator.

Purpose: The objective of this study is to investigate the relationship between middle and high school students' internet addiction, social support, self-efficacy and school life adjustment. Data were collected by self-administered questionnaires at middle and high school students located in Seoul and the metropolitan areas. Methods: The response rate is 94.8% (474 cases). The internet addition was measured by K Scale. The various methods of analysis were used, for example, frequency analysis, t-test, analysis of variance, and multiple regression analysis. Results: First, the mean score of internet addiction level is 2.07 in 5 Likert scale. the internet addiction level of the male students are higher than female students (p<.05). Second, as a result of classification of internet addiction groups by K Scale, 11 students (2.3%) are included in high risk group, 27 students (5.7%) are in potential risk group, 436 students (92.0%) are in general group. Third, the level of social support and self-efficacy of middle and high school students are very high. The difference of social support by internet addiction groups was not statistically significant. But, the difference of self-efficacy by internet addiction groups was statistically significant. The level of self-efficacy of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fourth, the difference of school adjustment by internet addiction groups was very statistically significant. The level of school life adjustment of the students in general groups are more higher than in high risk group and in potential risk group (p<.01). Fifth, the internet addiction have a negative correlation with school life adjustment. And the social support and self-efficacy have a positive correlation with school life adjustment (p<.01). Finally, in stepwise multiple regression analysis, the internet addiction affects negatively on the school adjustment. And the support of teacher among three types of them affects positively on the school life adjustment. And the social self-efficacy among two types of them affects positively on the school adjustment (p<.01). Conclusion: to adjust desirably the school environment of the middle and high school students, optimal and efficient management of internet addiction was needed in the future and the improvement and promotion of social support and social self-efficacy of the students was also demanded.
