To identify the factors influencing the charges per case of acute appendicitis and normal spontaneous vaginal delivery (NSVD), the personal data-base files and hospital-characteristics-reporting data files of Korea Medical Insurance Corporation were analyzed. One hundred and twenty-nine institutions were selected. The results of this study were as follows 1. The differences of charges per case with respect to hospital ownership, location, and equipment levels were statistically significant. 2. The results of multiple regression analysis revealed that bed capacity was the most significant variable in both diseases. 3. Ownership was significant variable in acute appendicitis. In NSVD, ownership and hospital equipment level were statistically significant. In conclusion, bed capacity was statistically the most significant variable in the analysis of charages per case. And we thought that the results of this study would influence the policy of the hospital bed supply.

This study was designed to investigate whether recruitment of physicians and dentists has been restricted to a social network, such as familial or kinship groups. The data was collected through a self-administered questionnaire survey distributed to a sampling of general physicians, specialists (internists, surgeons, other specialists), and dentists in August 1990. The major findings are as follows : 1) Total number of respondents was 405 ; of these, general physicians made up 48.9%, internists 10.4%, surgeons 15.8%, other specialists 4.9%, and dentists 20.0%. 2) 38.5% of the respondents had physicians or dentists in their immediate family or were related in some way to one. Those from urban areas, whose parents were highly educated, and whose father was a professional had more physicians or dentists in their family or kinship. 3) Parents of 7.1% of the respondents, brothers or sisters of 10.1%, grand parents of 1.7%, uncles or aunts of 7.9%, and cousins of 22.0% were physicians or dentists. 4) The majority of physicians or dentists in familial or kinship network specialized n surge, 32.3%, followed by internal medicine ; current worksites were noted as clinics by 30.8%, followed by general hospital, university hospital, and so on. The respondent's ma discipline tended to follow familial or kinship example. Consequently, it was concluded that physicians and dentists have been recruited within restricted familial or kinship network.

Recently the world is trying to reduce carbon emissions for global warming. Reducing use of fossil fuels can decrease carbon emission. In this reason the construction field has tried to reduce the use of fossil fuels relating to heating and cooling of buildings. An energy loss through the window system is about 10 to 30 percent of energy consumption of the whole building. The use of window film insulation is increasing to control the heat loss at the windows. The window film insulation absorbs solar radiation and makes the surface temperature of windows high. In this study, window surface temperature is measured, and an impact on indoor air is identified after attaching window film insulation. Finally, we found that cooling load decreases through simulation.

The theoretical simulation to predict the variation of supplying heat according to control methods of DHS(District Heating System) have been done by TRNSYS(A Transient System Simulation Program) 16. The physical system for DHS consists of primary and secondary supplying heating loop which is divided by based on heat exchanger for heating demand of building. The simulation results showed that control of secondary supplying heat had influenced more than primary supplying heat control to total energy consumption of DHS. And the outside temperature reset control of primary supplying heating loop could be reduced until about 4% overheating of each zone.

소규모 공동 탐지를 위한 시험지역에서 시추공 편차를 고려한 탄성파 토모그래피를 수행하였다. 시추공 편차보정방법은 일정 거리를 더하는 보정과 일정 각을 시추공간 거리에 고려하는 보정을 적용하였다. 시추공 편차를 고려한 토모그래피는 영상의 왜곡을 줄일 수 있어 공동을 명확히 영상화할 수 있었으며, 일정 각을 거리에 고려하는 보정방법이 공동탐지에 가장 효과적이지만 일정 거리 보정도 만족할 만한 결과를 얻을 수 있음을 알 수 있었다.

The objective of this paper is to evaluate the equilibrium price between PSTN and VoIP telephony services in the case of non-linear utility function. Currently there are two types of wired phone services we are known PSTN (Public Switched Telephone Network) and VoIP (Voice over Internet Protocol). The PSTN telephony which provide high quality service and VoIP which provides relatively low quality service form a vertically differentiated oligopoly. Therefore, the evaluation of the equilibrium price between PSTN and VoIP services is very important to wired phone service providers. The equilibrium price depends on the state of the service cost function has been proved different value. This paper was evaluated each equilibrium price for the state of the linear cost function and non-linear cost function. Subsequently, this paper analyzed the demand of both services and the equilibrium profit which can maximize the profit of both service providers.

Schwannoma, also named neurilemmoma, is a rare solitary and slow-growing tumor which originates from schwann cells of the nerve sheath. Schwannoma is a well-circumscribed, encapsulated masses that is attached to the nerve but can be separated from it. On microscopic examination, tumors show a mixture of two growth patterns, Antoni A and B. Surgical excision is the treatment of choice. Especially, Schwannoma of the tongue is very rare. We present a case of a 11-year-old child with a schwannoma of the tongue, measuring $1{\times}1cm$. During the operation the mass revealed itself as being encapsulated. The tumor was removed and diagnosed pathologically as a schwannoma.

To identify characteristics of elderly inpatients who had long term hospitalization in a general hospital, this study categorized into two groups who were hospitalized for less than 30 days and a group hospitalized for more than 30 days. To compare the groups the independent variables were the sociodemographical characteristics, the medical care utility characteristics, and the disease characteristics and finally analyzed factors affecting the hospitalization period. The data of 18,727 inpatients who were older than 65 years of age by the year 2005 were used and the data were analyzed using SPSS for Windows 12.0. With the results, it is necessary to provide intensive and positive management to elderly inpatients who belong to the more than 30 days group and also necessary to share roles and functions of hospital by medical network with local hospitals and clinics in order to manage long-term elderly inpatients and offer continuous post-management to discharged patients by encouraging them to use a long-term care center or by implementing an early discharge program. This study should provide many studies on how to manage the period of hospitalization efficiently on long-stay elderly inpatients in the future.

This paper considers a scheduling problem to minimize the total weighted completion time in the two-stage assembly-type flowshop. The system is composed of multiple fabrication machines in the first stage and a final-assembly machine in the second stage. Each job consists of multiple components, each component is machined on the fabrication machine specified in advance. The manufactured components of each job are subsequently assembled into a final product on the final-assembly machine. The objective of this paper is to find the optimal schedule minimizing the total weighted completion time of jobs. Three lower bounds are derived and tested in a branch-and-bound (B&B) Procedure. Also, three heuristic algorithms are developed based on the greedy strategies. Computational results show that the proposed B&B procedure is more efficient than the previous work which has considered the same problem as this paper.
