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.

무선통신 시스템에 있어서 스펙트럼 효율성과 전송속도의 극대화를 위해 MIMO(Multiple Input Multiple Output) 기술을 시스템에 적용하는 노련이 계속되고 있다. 최근 대두되고 있는 WiMAX와 LTE는 OFDM 기반 기술로서 CDMA보다 MIMO기술을 적용하기 쉽다는 장점에 의해 MIMO 기술을 기본으로 채택하고 있다. 하향 링크에서는 STC(Space Time Coding) 방식과 SM(Spatial Multiplexing) 방식을 사용하여 MIMO 방식을 기본 기술로 적용하였으며 상향링크에서는 C-MIMO(Collaborative MIMO) 기술이 사용된다. 특히, 상향링크는 양방향 데이터 통신을 활용한 다양한 신규 서비스가 제안되고 있어 전송 성능을 개선시킬 수 있는 C-MIMO의 성능향상이 기술 쟁점이 되고 있다. 본 논문에서는 C-MIMO 성능 향상을 위하여 기존에 사용되고 있는 신호간 직교성(OF: Orthogonal Factor)의 성질을 이용하여 단말 조합을 선택하는 방식(DPS: Determinant Pairing Scheduling)과 신호간 직교성을 사용하지 않고 단말 조합을 선택하는 방식(RPS: Random Pairing Scheduling)을 분석하였다. 또한 DPS와 RPS 방식을 보완한 새로운 알고리즘을 제안 하여 스펙트럼 효율을 높이는 방법을 고안하였다. 결과에 의하면 새로운 알고리즘을 통하여 RPS 대비 $2{\sim}3dB$ 이득을 보았으며 DPS에 비하여 현격하게 복잡도를 감소 시켰다.

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.
