Sevaral problems of administrative area sysem in Korea have been brought up for a long time. Because its frame has remained since Chosun and Japanese colonial period in spite of changing local administrative environment in accordance with rapid industrialization and urbanization. Recent reform of city (Shi)- county (Gun) integration is derived from this argument. But problems which permeate deeply overall system cannot be solved by partial reorganization of Shi-Gun. They may be rationalized only through the reform of the whole system. The aims of this study are to analyze problems of administrative area system entirelr and to discuss the direction of its reform from that point of view. Major problems of administrative area system are summed up into the followings. Firstly, it is found that administrative hierarchies are too many levels. Contemporary administrative hierarchical structure is 4 levels: regional autonomous government (Tukpyolshi, Jik'halshi, Do), local autonomous government (Shi, Gun), two leveis of auxiliary administrative area (Up, Myun and Ri). These hierarchies were established in late period of Chosun which transportation was undeveloped and residential activity space was confined. But today developing transportion and expanding sphere of life don't need administrative hierarchical structurl with many levels. Besides developing administrative technology reduces administrative space by degrees. Many levels of contemporary administrative hierarchical structure are main factor of administrative inefficency, discording with settlement system. Second problem is that Tukpyolshi and Jik'halshi - cities under direct control of the central government as metropolitan area - underbounded cities. Underbounded city discomforts residential life and increases external elects of local pulic services. Especially this problem is Seoul, Pusan and Daegu. Third problem is that Do-areas are mostly two larger in integrating into single sphere of life. In fact each of them consistes of two or three sphere of life. Fourth Problem is metropolitan government system that central city is seperated from complementary area, i.e. Do. It brings about weakening the economic force of Do. Fifth problem is that several cities divided single sphere of life. It is main factor of finantial inefficency and facing difficult regional administration. Finally necessity of rural parish (Myun.) is diminished gradually with higher order center oriented activty of rural residents. First of all administrative area system should corresponds with substantial sphere of life in order to solve these problems. Followings are some key directions this study proposes on the reform of administrative area system from that standpoint. 1. Principles of reorgnization -- integration of central dty with complementary area. -- correspondence of administrative hierarchical structure with settlement system. -- correspondence of boundary of administrative area with sphere of life. 2. Reform strategy -- Jik'halshi is integrated with Do and is under the contol of Do. -- Small Seoul shi (city) which have special functions as captal is demarcated in Seoul tukpyolshi and 22 autonomous distrcts of Seoul tukpyolshi is integrated into 3-4 cities. -- Neighboring cities (Shies) in single sphere of life are intrgrated into single city (Shj). -- Myun and Ri are abolished in rural region and new unit of local administrative area on the basis of lowest order sphere of life into which 3-4 Ries are integrated replaces them.

The purpose of this study was to investigate the effects of maternal psychological control and the disparity between children's temperament and mothers' demand level on children's externalizing and internalizing behavior problems. The participants of this study were 221 children aged 4 to 5 and their mothers from three kindergartens located in Busan and Gyeongsangnam-do. To measure children's behavior problems, the Preschool and Kindergarten Behavior Scales were used. Maternal psychological control was assessed by the Psychological Control Scale-Youth Self-Report. The Revised Dimension of Temperament Survey and DOTS-R: ethnotheory was used, to measure the disparity between children's temperament and mothers' demand level. The data were analyzed by means of descriptive statistics, t-test and hierarchical regression analysis. The results of this study were as follows. First, both for boys and girls, the disparity between children's activity temperament and mothers' demand level had a negative effect on externalizing behavior problems. However, maternal psychological control had no significant effect on externalizing behavior problems both for boys and girls. Second, for boys, the high level of maternal psychological control and the disparity between children's adaptive temperament and mothers' demand level had a negative effect on internalizing behavior problems. However, for girls, such effects were not significant.

The purpose of this study was to investigate the effect of organizational culture (group culture, development culture, rational culture, hierarchical culture) on job satisfaction based on the mediating effect of organizational trust on workers corporations. In particular, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. The results of the study of 8,615 workers in the manufacturing, financial, and non-financial industries in HCCP(Human Capital Corporate Panel) are as follows. First of all, the result of research showed that rational culture, group culture, development culture among organizational culture had a positive effect on job satisfaction. But, the hierarchical culture had a negative influence on job satisfaction. Second, rational culture, group culture, development culture among organization culture had a positive effect on organizational trust. But, hierarchical culture had a negative influence on organizational trust. Third, in the relationship between organizational culture and job satisfaction, the partial mediating effect of organizational trust was verified. In other words, although organizational culture directly affects job satisfaction, it indirectly affects job satisfaction through organizational trust. Fourth, it showed a significant moderating effect of communication between organization trust and job satisfaction. In other words, it was found that the group with high organizational trust in the relationship between organizational trust and job satisfaction had higher job satisfaction than the group without it. Finally, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. In other words, the indirect effect of organizational culture on job satisfaction through organizational trust is higher in the group with high communication capabilities. Through discussion and conclusion, the academic and practical implications, limitations, and research directions of this study were presented.

This study investigates convergent influence on job seeking stress and its association with self esteem, hopelessness, depression, locus of control and type A behavior pattern among some college women. The survey was administered to 531 college women in Jeonbuk area from March 28th to April 29th, 2016. The structured self-administered questionaries were used. The results of hierarchical multiple regression analysis show the following. The job seeking stress of respondents turned out to be significantly higher in following groups: a group in which self esteem is lower and groups in which hopelessness, depression, external locus of control and type A behavior pattern are higher. Their explanatory power was 43.2%. With the analysis of covariance structure, we could confirm relationship among the four factors such as self esteem, hopelessness, depression, locus of control, type A behavior pattern and job seeking stress. The results of the study indicate that the efforts, to increase self esteem, and to decrease hopelessness, depression, locus of control and type A behavior pattern, are required to reduce the job seeking stress of the college women. The results are expected to be useful for the development of program and policy to decrease the job seeking stress of the college women. In the following study, the analysis about additional factors of influence on job seeking stress will be needed.

Objective: Ovarian follicular development, which dependent on the proliferation and differentiation of granulosa cells (GCs), is a complex biological process in which miRNA plays an important role. Our previous study showed that miR-458b-5p is associated with ovarian follicular development in chicken. The detailed function and molecular mechanism of miR-458b-5p in GCs is unclear. Methods: The luciferase reporter assay was used to verify the targeting relationship between miR-458b-5p and catenin beta-1 (CTNNB1), which is an important transcriptional regulatory factor of the Wnt/β-catenin pathway. The cell counting kit-8 (CCK-8) assay, flow cytometry with propidium iodide (PI) and annexin V-fluorescein isothiocyanate (FITC) labeling were applied to explore the effect of miR-458b-5p on proliferation, cell cycle and apoptosis of chicken GCs. Quantitative real-time polymerase chain reaction and Western blot were used to detect the mRNA and protein expression levels. Results: We demonstrated that the expression of miR-458b-5p and CTNNB1 showed the opposite relationship in GCs and theca cells of hierarchical follicles. The luciferase reporter assay confirmed that CTNNB1 is the direct target of miR-458b-5p. Using CCK-8 assay and flow cytometry with PI and Annexin V-FITC labeling, we observed that transfection with the miR-458b-5p mimics significantly reduced proliferation and has no effects on apoptosis of chicken GCs. In addition, miR-458b-5p decreased the mRNA and protein expression of CD44 molecule and matrix metallopeptidase 7, which are the downstream effectors of CTNNB1 in Wnt/β-Catenin pathway and play functional roles in cell proliferation. Conclusion: Taken together, the data indicate that miR-458b-5p regulates ovarian GCs proliferation through Wnt/β-catenin signaling pathway by targeting CTNNB1, suggesting that miR-458b-5p and its target gene CTNNB1 may potentially play a role in chicken ovarian follicular development.

Objectives: This study was performed to identify factors related to perceived health status among patients with type 2 diabetes. Methods: This is cross-sectional observational study. Respondents were 106 visitors in an outpatient diabetes clinic of a university hospital. Self-report questionnaire which included general information inquiry, diabetes-related, sociopsychological factors, functional health literacy and perceived health status was used for this study. The data was analyzed by using descriptive statistics, independent simple t-test, one-way ANOVA, and hierarchical multiple linear regression. All analysis were conducted using SAS 9.3. Results: Among the respondents, 43.4% engaged in poorly perceived health status. After adjusting for control variables, functional health literacy is significantly related to perceived health status(${\beta}$=0.095, p=0.016). Conclusion: Independent of diabetes-related, sociopsychological factors, higher functional health literacy is associated with better perceived health status of patients with type 2 diabetes. In order to improve perceived health status in the type 2 diabetes patients, it is necessary to develop strategy to enhance the functional health literacy.

For content-based video indexing and retrieval, it is necessary to segment video data into video shots and then select key frames or representative frames for each shot. However, it is very difficult to select key frames automatically because the task of selecting meaningful frames is quite subjective. In this paper, we propose a new approach in selecting key frames based on visual contents such as region information and their temporal variations in the shot. First of all, we classify video shots into panning shots, zooming shots, tilting shots or no camera motion shots by detecting camera motion information in video shots. Then, in each category, we apply appropriate fuzzy rules to select key frames based on meaningful content in frame. Finally, we control the number of key frames in the selection process by adjusting the degree of detail in representing video shots.
