For the effective design of automated distribution center composed of Automated Storage/Retrieval System, Automated Guided Vehicle System, and Conveyor System, we proposed an analysis method to determining. design and control parameters with multiple performance objectives using Compromise Programming, which can resolve the dilemma of conflicting objectives. The Evolution Strategy generates the optimal solutions for each objectives. The Analytic Hierarchy Process selects the best solution among the alternatives generated from Evolution Strategy. The Regression Analysis formulates the objective functions for each objectives. By reducing deviations between goal values and target values generated from Analytic Hierarchy Process, Compromise Programming determines design and control parameters by compromising the multiple objectives formulated using Regression Analysis. When the parameters of system are changed, this proposed analysis method has a benefit of reducing costs and time without repeating whole simulation run.

In this paper we develop a model for the performance evaluation of defense R&D test development projects based on analytic hierarchy process. First, evaluation indicators are collected through the related literature survey and a delphi inquiry method. Second, stepwise multiple linear regression is used for developing a hierarchical structure for analytic hierarchy process in the evaluation model, which can make the selected evaluation indicators of the hierarchical structure independent. Also we verify the effectiveness of proposed indicators of the performance evaluation by comparing with the existing evaluation indicators. The developed indicators for the performance evaluation is more reasonable and practical than the previous indicators on defense R&D test development projects.

We design a DEA-AR model using multiple regression analysis with new methods which limit weights. When there are multiple input and single output variables, our model can be used, and the weights of input variables use the regression coefficient and coefficient of determination. To verify the effectiveness of the new model, we evaluate the efficiency of the Regional Corporations in Korea. Accordance with statistical analysis, it proved that there is no difference between the efficiency value of the DEA-AR using AHP and our DEA-AR model. Our model can be applied to a lot of research by substituting DEA-AR model relying on AHP in the future.

Based on extraction items derived from previous related studies on viewing experiences in art museums, this study is conducted to investigate extraction factors that affect viewing satisfactions and to suggest a guideline for an effective viewing environment by clarifying a hierarchy among the extraction factors. For this study, a survey was given to museum visitors, and statistical analyses were conducted on data obtained from the survey. The results of this study are summarized as follows; 1. From an analysis of extraction items that affect overall viewing satisfaction, space and art works were found to be relatively satisfactory. 2. From correlation analyses of extraction items, a degree of concentration on art works was found to most 'affect the viewing satisfactions of art museums. 3. From factor analyses, extraction items were reduced to 11 extraction factors, and a simple extraction structure affecting the viewing satisfactions in art museums. 4. From multiple regression analyses, a extraction factors were derived, and a relative hierarchy among the factors was found.

Purpose: This cross-sectional survey study explored the moderating effect of social support between hierarchy-oriented nursing organizational culture and turnover intention in clinical nurses. Methods: Data were collected using self-report questionnaires from 240 nurses working at three general hospitals in February 2018. Hierarchy-oriented nursing organizational culture, turnover intention and social support were measured using 5, 6, and 8 items, respectively, of validated instruments. Descriptive analysis and hierachical multiple regression were conducted using SPSS/WIN 21.0. Results: Nurses rated $3.66{\pm}0.50$ for hierarchy-oriented nursing organizational culture, $3.40{\pm}0.64$ for turnover intention, and $3.77{\pm}0.56$ for social support respectively. Nurses' turnover intention was positively correlated with hierarchical organizational culture, but negatively with social support. The moderating effect of social support was not significant in the relationship between hierarchical nursing organizational culture and turnover intention. Conclusion: It is required to improve the hierarchy-oriented nursing organizational culture. Institutional preparation and education are urgently needed to strengthen the boss and peer support for clinical nurses and finally to reduce turnover intention.

Purpose - The purpose of this study is to verify a role of organizational culture as antecedents to influence psychological empowerment of organizational members, focusing on service workers of casino companies. Therefore, this study sought to examine the question of each clan, adhocracy, market, and hierarchy culture that the workers perceive to influence their psychological empowerment. Thus, the current study examined the relationship between organizational culture and the psychological empowerment by empirical analysis. Research design, data, and methodology - This study chose four domestic casino companies that are run only for foreigners. Using an offline survey, it analyzed the questionnaire data of the 249 surveys collected from employees working in the sales and service sectors. Independent variables were four types of organizational culture: clan, adhocracy, market, and hierarchy. Dependent variables were four subcategories of psychological empowerment: meaning, competence, self-determination, and impact. As research methods, the study applied descriptive statistics, factor analysis, reliability analysis, correlation analysis, and multiple regression analysis, using SPSS 21.0 statistical program. Results - Among the organizational culture types, the clan and adhocracy cultures, which emphasize flexibility and autonomy, were relatively more important for the psychological empowerment of workers than the hierarchy and market cultures. Clan culture was the most important factor in terms of meaning and competence, and adhocracy culture was the most important factor in self-determination and impact. However, the hierarchy and market cultures that pursue control and stability were also cultural types that positively affected psychological empowerment of the workers. Hierarchy culture showed positive effects on meaning, competence, and impact except self-determination, and market culture had positive effect only on competency. Conclusions - The study found that organizational culture is an important predictor of psychological empowerment of the employees in casino companies and that important organizational culture types may be different for each sub-factor of psychological empowerment. It suggests that casino companies have to try to recognize and secure diverse organizational culture in order to activate psychological empowerment of their employees because they can provide quality service for customers. Therefore, it is necessary to create a harmonious and balanced culture between promoting flexible and autonomous organizational atmosphere, and stably controlling and operating the organization.

Purpose: The aim of this study was to determine the impact of nursing organizational culture types on innovative behavior and job embeddedness among clinical nurse. Methods: For this study a descriptive correlational study design was used. Participants were 293 nurses who had more than one year work experience. They were recruited from two university hospitals, one in Seoul and one in Gyeonggi province in 2016. Collected data were analyzed using SPSS/WIN 21.0 statistics program. Results: Hierarchy-oriented culture was the highest type of organizational culture perception and innovation-oriented culture, the lowest. Multiple linear regression analyses showed that, when age and total clinical experience were adjusted for, innovation-oriented culture perception was the most significant factor influencing innovative behavior, followed by task-oriented culture and relation-oriented culture in that order ($R^2$=.33, F=24.50, p<.001). Relation-oriented culture perception was the factor most influencing job embeddedness, followed by task-oriented culture and innovation-oriented culture in that order ($R^2$=.48, F=55.98, p<.001). Conclusion: More systematic and sustained organizational efforts are required to improve the hierarchy-oriented culture highly perceived by nurses and to emphasize innovation-oriented, relation-oriented and task-oriented organizational culture to increase innovative behavior and job embeddedness among clinical nurses.

The purpose of this study is to classify elderly patient in long-term care facilities using RUG(Resource Utilization Group)-III. It is designed by measuring patient medical characteristics and medical staff time. Elderly patients are classified into 7 categories by clinical(medical and behavioral) hierarchical typology of patients. Through the tertiary split, all 44 groups are formulated. This classification is explained by each patient resource(staff time) utilization level which is called CMI(Case-Mix Index). Major findings are as follows; 1. The objects in this study were classified into 35 groups out of 44 groups. The most frequent category is clinical complex category(CCC; 38.9%). And extensive service category(ESC; 18.8%), reduced physical function category(RPC; 13.1%), special rehabilitation category(SRC; 12.8%), and impaired cognitive category(ICC; 0.00%) are followed. 2. The mean of total CMI was $1.02{\pm}0.36$, ranging from 0.68 to 1.44(1 vs 2.12). The mean of CMI of SRC is only 1.17 which should be the highest. The means of ESC and see are equally 1.20. The means of CMI of CCI, ICC, BPC, and RPC were 0.90, 0.75, 0.83 and 0.96, respectively. 3. The validity of this classification was tested. Trend-test using Regression Analysis was done in the secondary split level. SCC, CCC, ICC, and RPC which covered 68.4% of this research objects showed linear trend of CMI in interim classification. This results were statistically significant. 4. In clinical hierarchy, the trend were showed linearity. But the multiple comparison of categories using Scheffe-test showed that SRC, ESC and see had same level of CMI means and CCC and ICC, too. This results were statistically significant. Classifying elderly patients with RUG-III, the results showed partly linear trend in clinical hierarchy and in interim classification in conclusion. But, in clinical hierarchy, it was failed to show the consistent order of CMI. It can be explained by two reasons. One is that this research subjects were overlapped in each clinical hierarchy group. And the other is that the some of the characteristics for clinical hierarchy is not appropriate for them. For the further study, it needs to have proper sample size and to modify RUG-III to K-RUG to consider our.. medical environment.
