Benjamin, Lusht, and Shilling(1998) suggested that the level of deposit can be used as a tool to resolve the problem of adverse selection by the leaseholder under the circumstance of information asymmetry. In this respect, this research aims to verify how the level of deposit and monthly rent mitigate the problem of information asymmetry existing in the office market in Seoul. So far, the analysis of the office market in Seoul has been difficult due to the fixed rate of deposit and monthly rent. This research attempts to adopt the concept of occupancy cost, a global standard indicator that would replace the default risk of monthly payment for analyzing the market. As a result of a series of empirical analysis, the lessors tend to add about 9 percent of risk premium to the occupancy cost to hedge against the default risk of monthly payment. It allows for estimating at what extent one should reflect the leaseholder's default risk of monthly payment for operating deposit and monthly rent in the office building lease market.

송전용량 증가를 위해 개발되어 최근 본격적으로 사용되고 있는 STACIR/AW 송전선은 송전용량의 증가에 따라 그 운전환경도 변화하여 연속사용온도의 경우, 기존 ACSR 전선의 90t에 비해 높은 $210^{\circ}C$로 규정 되어 있을 만큼 고온에서 운전되고 있다. 따라서 STACIR/AW 송전선은 이도설계와 그 운용에 있어서 운전 온도 상승에 따른 각별한 주의관리가 필요하다 실제 STACIR/AW송전선은 그 설계단계에서도 이와 같은 고온운전 환경을 고려하여 고온에서도 소정강도를 유지하는 내열 Al도체와 이도제어를 위한 낮은 열팽창 특성의 INVAR합금(Fe-35Ni계 합금)을 강선으로 하는 특화된 재료로 구성되어 있다. 그러나 이와 같은 재료 설계적 보완책에도 불구하고 실제 송전선은 전선의 자중, 철탑 간에 형성된 가설장력과 같은 다양한 응력이 고온환경에서 부하되는 복합 열화 상태에 노출되어 있고, 이것은 재료학적인 관점에서 크릴 변형 발생의 가능성을 높이고 있으나 이것에 대한 연구 또는 실험결과는 크게 미미한 실정이다. 본 연구에서는 STACIR/AW $410mm^2$ 송전선과 그 구성소재를 대상으로 $200^{\circ}C$, $300^{\circ}C$에서 장시간 열화한 후, 구성소재의 탄성계수, 열팽창계수 및 STACIR/AW전선의 크림변형 거동을 조사하여 열화에 노출된 STACIR/AW 송전선의 이도변화 거동을 규명하고자 하였다.

Different countries around the world, using their traditional culture as a background, are promoting new changes and reformation in development and publicity method of cultural contents to promote national interests and to increase their competitiveness. Also, as the citizen's standard of living and quality of living goes up, various demands for the enjoyment of traditional culture goes up accordingly as well. As the cultural assets environment become more complicated and diverse, there is a need for systematic management and preservation plan. Keeping these viewpoints in mind, the geo-spatial information provision service using the web provides various forms of services such as satellite imagery, terrain, and 3D viewing, enabling the user to gain concrete spatial information on specific areas. The geo-spatial information using 3D modeling is done only in limited spaces because of construction expenses or difficulties in management and maintenance. In this thesis, I would like to propose Effective method for the GoogleEarth Uploading through simplification of 3D object for the publicity of traditional buildings and Cultural Resources and Tourist Attractions.

Many users visit websites every day to perform information retrieval, shopping, and community activities. On the other hand, there is intense competition among sites which attempt to profit from the Internet users. Thus, the owners or marketing officers of each site try to design a variety of marketing strategies including cooperation with other sites. Through such cooperation, a site can share customers' information, mileage points, and hyperlinks with other sites. To create effective cooperation, it is crucial to choose an appropriate partner site that may have many potential customers. Unfortunately, it is exceedingly difficult to identify such an appropriate partner among the vast number of sites. In this paper, therefore, we devise a new methodology for recommending appropriate partner sites to each site. For this purpose, we perform site clustering from the perspective of visitors' similarities, and then identify a group of sites that has a number of common customers. We then analyze the potential for the practical use of the proposed methodology through its application to approximately 140 million actual site browsing histories.

Recently many Hotels have implemented and operated the Hotel Information System(HIS). These HIS-implementation evoke the significant changes in hotel management. So many interest and researches in HIS has received the spotlight from the hotel managements. Many researcher about HIS focused on the Critical Success Factors (CSF) from the viewpoint of HIS implementation. At this moment we need also the research about significance change of CSF with the laps of time. This kind of research are very critical for the successful operation of HIS. To achieve the objectives of this paper, the Innovation-Theory of E. M. Roger was implemented. As the result of this research we can get the various maturity point of each CSF with the laps of time. For the data gathering many major hotel in Korea were interviewed, and 84 valid questionaires were used for data analysis. The Cronbach's ${\alpha}$ was 0.7239, which means all data were significant.

Recently, BIM(Building Information Modeling) has been applied to the infrastructure such as road and bridge, and information about the outside environment of buildings is needed for maintaining and managing the large urban facilities. In addition, the convergence between spatial information and Big-data has a large potentiality, in respect that considerable profits and developments in other application problems such as various simulations and urban plans, national land security, may be brought about on the basis of the interoperability of information between BIM and GIS. Therefore, this study attempted to suggest the development direction of a model integrating building for spatial information analysis and city on the subject by comparing and analyzing difference between information system and shape expression of IFC, CityGML and LandXML to efficiently link information between IFC as a standard model of BIM and CityGML as a standard model in the GIS sector and to prepare a basic fusion strategy and a method of utilization between BIM and GIS. The result of the study are as follow. Firstly, contents and structure of IFC, CityGML and LandXML are compared and analyzed. Secondly, the development direction of iBUM(Integrated Building and Urban Model) suggested, which is based on convergence technology for analysis of space information. Finally, a strategy and method of the BIM and GIS are proposed in the iBUM environment.

This study is to identify the relationship in non-profit social welfare organizations(SWOs) between financial sources and service delivery. Especially the impact of the former to the latter is its main concern. For this purpose, gathered are the 1992, 1999 financial reports of those study organizations, and some qualitative data on a number of the organizations collected by the author is also used for verifying and interpreting the data. Gronbjerg's study(1992) provided an analytical tool for decomposing financial structure of human service organizations, and resource-dependency perspective was a theoretical framework for interpreting the impact of financial composition to service delivery. The findings are as follows: (1) Between 1992 and 1999, there was a noticeable change in financial composition among SWOs. Government subsidies has increased in terms of both amounts and percentages, for residential facilities 75% to 82% and for nonresidential facilities 37% to 47%. Funding from donations shows no abrupt changes, although absolute amounts were slight increasing. Fees were sharply decreasing, especially for the non-residential facilities which previously enjoyed them as valuable resources for preventing unnecessary influence from government. (2) The funding sources of SWOs and their strategies to acquire them has impact on service delivery. Although non-government fundings(donations and fees) were found to give elasticity to SWOs, various problems associated with acquiring them (i.e., changing the clientele) would prohibit SWOs from fully concentrating to those fundings. Meanwhile, government fundings are characterized as stable, and, as such, most of the SWOs prefers. Limited elasticity, red-tape, 'sacrifice of quality of service' over efficiency, etc. are referred to the problems.

Re-coating of the mirror is one of the important things to maintain the performance of a telescope. The metal coated on the mirror reflects light, and if the reflectance decreases, then the telescope's performance decreases, so the mirror must be periodically recoated. It is important to predict re-coating cycles for military telescopes and to develop maintenance plans not only for performance, but also for the telescope's availability for missions and the maintenance costs for long-term use. However, most similar telescopes used for astronomy research determine recoating cycles based on experience and operating conditions, and not for prediction of recoating. Therefore, this study predicts the cleaning cycles and re-coating cycles of a military telescope's mirror by using simulation. First, this study analyzed similar cases of domestic and foreign astronomy research institutes and the study also reviewed the need for re-coating and predicting re-coating cycles. Second, this study developed simulation for predicting cleaning and re-coating cycles according to data analysis and modeling. Finally, the study predicts cleaning cycles and re-coating cycles according to varying reflectance reduction (5%, 10%, 15%, 20%) and cleaning conditions (per 3 months, 6 months, 1 year and 2 years). As a result, this study suggests reference criteria to develop the planning for military telescopes and their maintenance.

Private detectives and investigators offer many services, including executive, corporate, and celebrity protection; pre-employment verification; and individual background profiles. They also investigate computer crimes, personal injury cases, insurance claims and fraud, child custody and protection cases, missing persons cases, and premarital screening. This paper focuses on a private detective or investigator system in most developed U.S.A, but it is not easy to describe that system. Licensing requirements vary in U.S.A. Some States have few requirements, and many other States have stringent regulations. A growing number of States are enacting mandatory training programs for private detectives and investigators. Employment and need of private detectives and investigators is expected to grow faster than the average for all occupations. Thus, it is reasonable that korean government should permit private investigation service find the way to minimize the side effects of private investigation service instead of banning the service totally.
