As enterprises use ATM networks for their private networks and as these private networks use public ATM networks for wide area communication, the need for the customers to be able to manage both private and public networks. Currently, some standardization work is being done towards providing this capability to customers. In this paper, we propose a new customer network management (CNM) system architecture for the management of both ATM a private network and a public network in a uniform way. The particular features of the proposed architecture lies in the efficient support of the complex hierarchial TMN manager-agent relationships at M3 and M4 interfaces, and the support of SNMP and CMIP integration which is necessary for the implementation of a CNM system. The TMN hierarchical many-to-many manager-agent relationships are realized by the utilization of CORBA-Based SMK (Shared Management Knowledge) implementation. We have also implemented the prototype of a ATM CNM system, and measures the performance for the demonstration of the suitability of the proposed architecture.

Empirical analysis was based on the data of 692 hotel employees from Seoul and Gyung-gi province. To test the relationship between job characteristics and service quality, multiple regression analysis was applied, and hierarchial regression analysis(Cohen & Cohen, 1983) applied to test the moderating effects of gender and tenure. Multiple regressional analysis showed that job importance, job variety, and feedback had an positive impact on tangibility, reliability, responsiveness, assurance, empathy, but autonomy had a negative impact on tangibility, reliability, responsiveness, assurance. Hierarchical regressional analysis showed that gender had moderating effects on 4 relationships between job characteristics and service quality, and tenure had moderating effects on 3 relationships.

The Office of Science and Technology Innovation (OSTI) was created by a different method of organizational change from that of precedent administrative reforms. According to results of the new method, the OSTI case can be widely applied to other ministries as an alternative model for governmental reform. The theory part introduced two approaches of organizational reform, namely structural approach which focuses on the level of hierarchial authority and process approach which emphasizes the flow of information/expertise in organizational operation. It also discussed various ways of understanding for S&T policy coordination. After this, the paper reviewed details of the OSTI reform with special reference to implications for the mode of S&T policy coordination. It concludes that the OSTI may offer an opportunity to strengthen the coordination mechanism of the process approach.

Objective : This study was done to investigate the correlation between general quality of life(QOL) and disease specific QOL of tinnitus patients. Methods : 2009 National health and nutrition survey(NHNS) data were employed for analyzing the mean estimates of total population and tinnitus sub-group patients, and predicting the regression equation of mapping between EQ-5D and disease severity. Baseline statistical analyses and normality tests were done by using Student t-test, Chi-square test, Shapiro-Wilk test and ladder test. Hierarchial regression analyses were performed using related variables and predicted the optimal regression equations. Statistical significance was achieved if the probability was less than 5%. Results : Firstly, the standardized prevalence of tinnitus patient in South Korea was 18.69% and over 90th age-group was relatively higher than other groups. Mean value of domestic QOL measured by EQ-5D was estimated as 0.9486 and QOL of tinnitus subgroup(0.9169) was lower than the non-tinnitus subgroup(0.9559), significantly. Stratified by age and sex, QOLs of all sub-groups with tinnitus were lower than without tinnitus sub-groups significantly. Regression equations from 2009 NHNS data were developed using hierarchial regression analysis which is as follows. $$Y_{EQ-5D}=0.9224-0.0079{\times}T1-0.0261{\times}T2-0.0951{\times}T3+\sum_{i=1}^{n}{\beta}_i{\times}X_i\\{\hspace{95}}(0.0106){\hspace{3}}(0.0037){\hspace{30}}(0.0072){\hspace{30}}(0.0038)$$ ($X_i$=Other explanatory variables except Tinnitus QOL1, 2, 3, ${\beta}$= Regression Coefficient of Model 4) Conclusion : We confirmed the correlation among THI and EQ-5D and HUI-III, and developed the inference for regression equation of EQ-5D.

Purpose: This study was conducted to identify factors that influence on self-determination for withdrawal of life-sustaining treatment in the community dwelling elderly. Methods: This study used a descriptive correlational design. A convenience sample of 201 elderly were recruited from a welfare center located in Seoul, Korea. Data collection was done from September 1 to September 18, 2015. Four survey questionnaires were used: Multidimensional Scale of Perceived Social Support (MSPSS), Life Satisfaction Index-Z (LSI-Z), Attitude on Do Not Resuscitate (DNR), and Self-determination for Withdrawing Life-sustaining Treatment. Data analysis was done by t-test, ANOVA, Pearson's correlation, and hierrarchical multiple regression. Results: Hierarchial multiple regression showed that the factors predicting the level of self-determination for withdrawing life-sustaining treatment were educational level, DNR experience in family, life satisfaction, and DNR attitude. These factors explained 44% of the self-determination for withdrawing life-sustaining treatment in community dwelling elderly. Conclusion: The results of this study suggest developing educational programs aiming at changing elderly's DNR attitude positive ways so that they can enhance self-determination for withdrawing life-sustaining treatment. Further study is needed with more elderly population in extended areas.

Purpose: The purpose of this study was to identify factors contributing to health-related quality of life in patients under rehabilitation after stroke. Methods: A descriptive correlational study design was used. Ninety-two stroke patients under rehabilitation from a university hospital were included. Data were collected on March and April, 2013 using structured questionnaires. Hierarchial multiple regression analysis was used to identify factors influencing health-related quality of life. Results: There were significant differences in health-related quality of life according to type of impairment. The health-related quality of life had significant correlations with age, functional dependency, and stress. Factors influencing health-related quality of life for stroke patients under rehabilitation were stress, functional dependency, type of impairment, and age, which explained about 34.5% of total variance. Conclusion: To promote health-related quality of life for stroke patients under rehabilitation, stress and functional dependency should be managed in this population, especially for older adults. Also these results can be utilized in the development of program for helping rehabilitation of stroke patients. The effect of depression and anxiety on health-related quality of life should also be addressed in future research.

Purpose: In this study factors affecting job satisfaction and turnover intention of nurses were explored in the context of organizational culture, self- leadership, and empowerment. Methods: Participants were 286 nurses drawn from 3 general hospitals. Data were analyzed using t-test, one-way ANOVA, Pearson correlation, and hierarchial multiple regression with the SPSS/WIN 18.0 program. Results: Significant differences in job satisfaction and turnover intention were found according to organizational culture types. Significant positive correlations were found between self-leadership, empowerment, task oriented organizational culture, relationship oriented organizational culture, innovation oriented organizational culture and job satisfaction. On the other hand, significant negative relationships were found between empowerment, relationship oriented organizational culture, innovation oriented organizational culture and turnover intention. The factors that enhance job satisfaction were found to be higher innovation-oriented organizational culture. Lower turnover intention was shown to be positively associated with relationship- or innovation oriented organization culture. Conclusion: Innovation oriented organizational culture is needed in order to raise job satisfaction and reduce turnover intention of nurses.
