This paper porports to explicate the factors determining the scope of public health in advanced capitalist countries. A few studies have veen conducted for such a purpose, yet even these studies show the deficiency of failing to consider a very important factor : the influence of medical profession. Since medical profession has played a significant role in the health policymaking, it is necessary to incorporate the hypothesis that assumes the causal links between the differing medical professional power and the vrying scope of public health. Following this view, this paper examined the various hypothese, including the power of medical profession, and found that the variables related to medical professional power as well as social democratic perspectives are its significant factors. In particular, our result shows that the power of medical profesion is the most important determinant, thereby supporting the hypothesis developed in this paper.

Maximum power point tracking (MPPT) under the partial shading condition is a challenging research topic for photovoltaic systems. Shaded photo-voltaic module result in complex peak patterns on the power versus voltage curve which can misguide classical MPPT algorithms. Thus, various kinds of global MPPT algorithms have been studied. These have typically consisted of partial shading detection, global peak search and MPPT. The conventional partial shading detection algorithm aims to detect all of the occurrences of partial shading. This results in excessive execution of global peak searches and discontinuous operation of the MPPT. This in turn, reduces the achievable power for the PV module. Based on a theoretical investigation of power verse voltage curve patterns under various partial shading conditions, it is realized that not all the occurrences of partial shadings require a global peak search. Thus, an intelligent partial shading detection algorithm that provides exact identification of global peak search necessity is essential for the efficient utilization of solar energy resources. This paper presents a new partial shading determinant algorithm utilizing adaptive threshold levels. Conventional methods tend to be too sensitive to sharp shading patterns but insensitive to smooth patterns. However, the proposed algorithm always shows superb performance, regardless of the partial shading patterns.

Nurses are medical personnel, who play a key role in supporting patient care, so it is important to supply them adequately in balance with ever increasing medical demand. But there appears severe shortage of nurses in some hospitals because of their uneven distribution, especially in small sized-hospitals and rural-hospitals. As nationwide distorted distribution of nurses in Korea is just like what monopsony model(a kind of market structure model) tells us, it is attempted to explain this situation of nurse labor market in Korea on the basis of monopsony model and presented in this paper. Specifically, determinants of nurse wage and the level of their relative employment were examined, and monopsony impact on their wage and the level of relative employment controlling those determinants were studied. Major results of this study arc as follows. The most important determinant of nurse wage level in this study was the wage level of a local community where each hospital located Hospital owner's characteristics an educational function of each hospital were also important factors. With these factor controlled, it was found that monopsony power of each hospital was negativel associated with nurse wage level as expected. 1% increase in monopsony power of hospital(measured by Herfindah-Hirschman Index) reduced nurse wage by $5,674{\sim}19,19$ won(in Korean currency). With regard to the level of relative employment, the most important determinant wa the capacity for supplying nurses of the local community. Again, hospital owner characteristics and educational function of each hospital were also important. With these factors controlled, it was found that monopsony power of each hospital was negative associated with the number of nurses per bed, as expected. 1% increase in monopsony power of each hospital(again measured by Herfindah-Hirschman Index) reduced the number of nurses per 100 bed as much as $0.46{\sim}0.67$. In conclusion. structural factors of nurse labor market influence the instability of nurse labor supply in Korea. Further consideration for these market structural characteristics needed for policy making related to nurse resource allocation.

본 연구는 주거용 부동산시장을 중심으로 부동산의 매매과정에서 구매자 입장에서 본 협상력의 결정요인들을 추출하고자 하였다. 구매자는 주택의 매수 이외에 임대 등 여러 대안을 가질수록, 매매과정에서 관련 정보가 많을수록 주택의 매매 가격협상에 있어서 유리하다. 그리고 협상과정에서 외부나 계약 당사자 간의 상황이 변경되었을 경우, 얼마나 유연하게 대처하는가의 정도와 상황변경에 따르는 비용이 적게 들수록 주택의 매매협상에서 유리하게 작용됨을 볼 수 있다.

A review of shows that past research has focused predominately on foreign market entry strategy issues in relatively well-established firms. These studies have either ignored venture firms or have failed to treat these firms separately. Only recently, researchers have broadened their search to include aspects of the foreign market investment of the venture. The purposes of this study are to identify and explain the impact factors such as ownership specific advantage, transaction cost, and location specific advantage on the choice of foreign market entry strategy for venture firms. To find the perceived the foreign market entry strategy and determinant factors, 130 venture CEOs from the computer and communications equipment industries were asked to describe their venture's foreign market entry strategy through 17 questionnaire items on competitive method. Using factor analysis, the six determinant factors were categorized. To test the relationships between the foreign market entry strategy and factors such as ownership specific advantage, transaction cost, and location specific advantage, the data collected by questionnaire from 92 ventures. The main results of this research are as follows. First, the factors of ownership specific advantage have partially significant impact on the foreign market entry strategy of venture firms, Second, the factors of transaction cost have significant impact on their foreign market entry strategy. Third, the factors of location specific advantage have significant impact on their foreign market entry strategy. This study has produced evidence to demonstrate that the foreign market entry strategy profile of venture firms can be distinguished from those of relatively well-established firms. An expanded study would allow for stronger conclusions regarding the relative explanatory power of individual variables in the method. Additional research is also needed to examine other determinant variables connecting foreign market entry strategy.

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.
