This study was conducted to examine the determinant factors for expenditure of the medical insurance program for self-employeds based on the analysis of 1991 'The Medical Insurance Program for Self-Employeds Statistical Yearbook', and also similar yearbooks in the metropolitan and other provinces. The major findings are as follows : We have divided benefits into these four components such as the utilization rate for out-patients, expenses per claim for out-patients as paid by the insurer, utilization rate for in-patients, and the expenses per claim for in-patients as paid by the insurer, in order to examine the determinant factors for it. The results of the study revealed the following findings, in urban areas, the supply of medical care had more influence on the benefits than other demographic and economic variables, while, in county areas, both the supply of medical care and the rate of those aged over 65 affected the provision of benefits. The determinant factors for financial balance of the medical insurance program for self-employeds are, first, the determinant factor for administrative expenses was the number of households. The more the number of households, the less the administrative expenses per the insured. This shows that the economy of scale is being. And so, the administrative district must be taken into consideration in the incorporation of small regional medical societies and should be re-organized for more efficient management. Second, in urban areas, the supply of medical care had more influence on utilization rate and expenses per claim as paid by insurer, and therefore it is necessary to control it. In county areas, the supply of medical care and the rate of those aged over 65 raised the utilization rate and expenses per claim as paid by insurer. For the financial stability of county areas, a common fund for medical care for the aged and expansion of finance stabilization fund would be necessary. But, in county areas, it would be unnecessary to control the supply of medical care because it was much more insufficient than in urban areas. The vitalization of public health facilities must be carried out in county areas, for they reduced benefits. Sice the more insured in a single household, the less the utilization of the medical insurance program, benefits for habilitation at home should be given consideration. The law of majority and the economy of scale were applied here, and therefore the incorporation of regional medical societies must be taken into consideration. In integrating regional medical societies, it would be absolutely necessary to review the structural differences among all regional medical societies, the medical demand of each region, and also the local characteristics of each region.

This paper analyzes the dynamics and nature of regional business cycle synchronization for East Asian countries in the period of 2000:Q1-2011:Q4. Estimating a dynamic two-factor model extracts the common factor and the nation-specific factor from both the macroeconomic aggregates and plausible driving forces of regional business cycles. Evidence for regional business cycle synchronization is particularly strong for Korea, Malaysia and the Philippines, while Japan shows weak evidence of regional synchronization. On the other hand, Indonesia, Thailand, Singapore and China are decoupling from regional business cycles. The driver of monetary aggregate is the most significant determinant of regional fluctuations of macroeconomic aggregates, whereas oil price and productivity are on average important driving forces of nation-specific fluctuations of real economic activities.

Globalization of R&D activities of multinational firms is becoming important in compared with the past, because of increasing globalization of world economy. So, every country tries to attract foreign investment including R&D activities. In this paper, effects of several factors, which determine the scale of foreign subsidiary's R&D activities in local market, are analyzed. Through the review of previous literature, I found that three groups of determinant factors. The first one is the factor which is related to characteristics of local market, such as competitive situation of local market, accessability to research institutions, etc. The second group is the factor which is related to relationship between foreign subsidiary and its mother company. The dominant factors of this group are operation strategy of foreign subsidiary, competitiveness of mother firm, and equity structure of foreign subsidiary. Finally the characteristics of industry affect to the scale of foreign subsidiary's R&D activities. Among these factors, 6 factors are chosen to investigate empirically. For the empirical investigation, 107 foreign subsidiaries among KOITA(Korea Industrial Technology Association)'s list are chosen. Each subsidiary has more than 50% of foreign equity and implement R&D activities in Korea. The results show that sales volume of foreign subsidiary is dominant influencing factor in determining scale of R&D activities in Korean market. And also I found that currently established firms are implementing more R&D activities than old established firms. This is quite interesting finding. However, R&D activities of foreign subsidiary are not vitalized in Korean market. It probably means that Korean government and Korean business partners have to make effort to enhance foreign firms/ R&D activities, because it could contribute technological and economic development of Korean market.

In order to maximize spectrum efficiency and data rate MIMO(Multiple Input Multiple Output) is adopted to wireless system. OFDM-based WiMAX and LTE accommodate MIMO as mandatory technology. STC(Space Time Coding) and SM(Spatial Multiplexing) are used in downlink while in uplink C-MIMO(Collaborative MIMO) is used to improve data throughput. In this paper conventional pairing schemes, RPS(Random Pairing Scheduling) and DPS(Determinant Pairing Scheduling) are analyzed. From the analysis the performance of DPS algorithm is better than that of RPS because DPS measures orthogonal factor between paired users. However, there are potential problems such as hardware complexity and performance. To overcome the issues Power-Based Scheduling(PBS) algorithm is proposed for C-MIMO. PBS can provide higher performance compared to RPS and dramatically reduce hardware complexity compared to DPS

The purpose of this study is to draw the factors that makes the visitors decide to visit the art-museum and verifying the influence of visit determinants on recommendation intention and revisit intention. Visitors to Gwangju Museum of Art and Gwangju Biennale in Gwang-ju city were chosen for this study. Data were collected for 30 days from September 15 to October 14, 2018. A total of 350 visitors were attended in this research and finally 315 samples were used for the empirical analysis. The result of this study showed that 4 determinant factors(Escape from the ordinary, self-development, novelty, culture experience) of visiting art-museum were identified which all influences on behavioral intention(recommendation intention, revisit intention). Particularly, 'novelity' is the major factor influences on recommendation intention followed by 'escape from the ordinary' factor. Moreover, 'escape from the ordinary' factor influences the most on revisit intention among all determinants of visiting art-museum.

The purpose of this study is to examine the determinant factors of maintaining employment in young adults with intellectual disabilities who took part in a vocational training program and was employed. The determinant factors were from four areas, such as physical competence, job-related task performance, emotional behaviors, and functional adaptive behaviors. 64 young adults with intellectual disabilities participated in this study. The participants' capacities were examined during the program, and then their job retention was examined through a follow-up survey six month after the end of the program. Tests contained hand dexterity, grasp strength, finger strength, visual-perception, Survey of Functional Adaptive Behaviors, and Observational-Emotional Inventory-Revised. After data collection, the data were analyzed by binary logistic regression. The results indicated that dexterity in both hands (OR= 1.123) in physical competence, anxiety (OR= .733) and socialization (OR= .429) in emotional behaviors, and academic skills (OR= 1.077) and vocational skills (OR= 1.542) in functional adaptive behaviors were significant determinant factors. These significant factors which affected job attention were consistent with the results from previous studies, and should be considered when designing and constructing an effective career and vocational education program for young adults with intellectual disabilities.

The purpose of this thesis is to analyze empirically the relationship between market structure, measured by Herfindahl-Hershmann Index(HHI), and financial factors, and innovation in Korean industry panel datasets for 2000-2006. Results show that debt ratio and scale of the firm has a consistent positive effect on the investment in research and development. As more scale of the firm is getting bigger, the investment in R&D decrease. Also, as more debt ratio of firm rise, the investment for innovation increase. Concentration ratio, the HHI and the classification factor of High-tech industry and Low-tech industry has a consistent positive effect on the innovation. Factors affecting the investment in research and development include market structure and characteristics of industry as well as the internal affairs of the firm.

The aim of this paper is to examine the determinants of residential satisfaction and attachment according to the urban multi-family dwelling types. On the basis of the surveys, the factor analysis and regression are employed as the empirical analysis on residential satisfaction and attachment in Daegu metropolitan city. The major findings are as follows; First, as for post-occupancy evaluation of residential environment of building and outside, the residents of complex type of multi-family housing satisfied with most of items more than studio type except the location, amenity facilities around building and utilities fee. Second, about the Residential Satisfaction and Attachment by types, the residents of complex type of multi-family housing satisfied with most of items more than studio type too. Third, the determinants in residential Satisfaction of complex types are 'welfare and amenity facilities factor', 'maintenance factor' and 'location factor'. On the other hand, the determinants in residents of studio type are 'inexpensive rent fee factor', 'welfare and amenity facilities factor' and 'maintenance factor'. Going forward, this research will help us better understand residential satisfaction from the point of residents and find new ways to improve resident satisfaction and attachment.

Direct manipulations are composed of pointing operations and dragging operations. In order to find the optimum design parameters (such as C/D ratio, moving direction) for the direct manipulation of a GUI(Graphical User Interface), an ergonomic experiment was devised (2*4*3*8 design) to measure the performance of a mouse (Microsoft) and a trackball (Logitech). The results showed that the mouse was more suitable for the direct manipulation (expecially for the dragging operation) than the trackball, and the suitable C/D ratio was 10 (for the mouse) and 16 (for the trackball). Also the movement direction was a determinant factor in trackball performance.
