The road sinks in the sewer line or subway section are affected by the ground characteristics. Therefore, it is necessary to accurately identify the relationship between the soil properties and the ground motion in the area where cavities occurred in order to establish a countermeasure against the road sink. In this paper, simulation was performed by using EDEM program, which is one of the Discrete Element Method programs, for sandy soil and clayey soil, which are most common in alluvial deposits, with different locations and sizes of cavities in the underground. As a result, it was found that the sink size occurred more in the sandy soil than in the cohesive soil. Deeper and larger cavity is more likely to occur the road sink In the sand soil model while road sink in the clay model is easy to occur when the cavity is more shallower.

This research analyze the demand of the residents against the public housing remodeling of national housing scale $(85m^2)$, focusing on residents and their tendencies within their dwelling spaces. The analysis determines the most appropriate patterns and spatial connections within the floor plan. The result includes that there are two types of the classification into an urban oriented propensity (45%), 'The center of city, the apartment and the convenience' etc, and a rural oriented propensity (55%), 'The pastoral, the house and the circumstance' etc, based on their lifestyle values. Also there are three interior propensity classifications, those tending to warm and sensitive variable space (42%), western and gorgeous dynamic space (34%) and oriental and popular static space (24%). The research illustrated the residents' desired space planning options, based on the analysis of the residents' preference patterns which is various.

This study aims to evaluate the feasibility of remodeling business by predicting the future price of apartment house after remodeling using Hedonic Price Model. The data concerning such 9 independent variables as location, unit size, unit plan, landscape, parking, the number of elapsed years after completion, number of units, mechanical performance, interior from 25 regions in Seoul metropolitan city were collected and evaluated by established evaluation criteria. The coefficients affecting the price of apartment unit were made by way of linear multi-regression and put into Hedonic Price Model. The feasibility evaluation model for apartment was made and verified by data of remodelled apartment. The predicted results using suggested evaluation model coincide with actual apartment market situations.

The purpose of this study is to describe and analyze the characteristics of seven major cooperative storage facilities for academic libraries in the U.S.A, Australia, and Scotland in order to provide a frame of reference for such a facility in Korea. Analyzed are unique characteristics of these storage facilities in relation to their physical facilities, uses and services for collections, participating organizations, ownership of resources, and integrated library management and access systems. Some objectives of operations and physical environments are shared by these storage facilities, and have some implications for the development of cooperative storage facilities in Korea.

The purpose of this study is to suggest the characteristics of a cooperative storage facility for academic libraries in Korea. For this facility, discussed are how to select a site, build physical facilities, recruit participating organizations, prepare for selection criteria and ownership of resources, confirm service policies, and implement a integrated library management and access system. It is emphasized that a cooperative storage facility for academic libraries in Korea should ensure the optimum use of space on campus, preserve "the last copy" which is not frequently used, but still has scholarly values, and extend the effective and efficient resource sharing among participating libraries.

올림픽이나 월드컵과 같은 대규모 국제행사가 개최되면 개최국의 근심거리 중 빠질 수 없는 것이 바로 테러예방이다. 지난 8월 8일 개막된 베이징 올림픽의 열기가 한층 고조되고 있는 가운데, 중국 역시 올림픽 개최에 앞서 테러방지를 위한 보안활동을 강화하고, 또 테러 발생에 대비한 훈련에 많은 노력을 할애하고 있는 것으로 알려져 있다. 하지만 테러는 총이나 폭탄과 같은 무기들로만 이뤄지는 것은 아니다. 오히려 사이버 공간에서 발생하는 침해사고는 우리가 일반적으로 생각하는 테러와는 전혀 다른 엄청난 피해를 안겨줄 수 있다. 요즘처럼 사회적 활동의 많은 부분을 IT에 의존하고 있는 상황에서는 더욱 그러하다. 이런 상황에서 아시아 주요 국가의 CERT가 베이징 올림픽 기간 중 발생할 수 있는 각종 사이버 침해사고에 대비한 공동의 노력을 펼치고 있다.

우리나라는 1957년 창설 회원국으로 IAEA에 가입한 이래 우리나라 원자력 산업의 발전에 따라 보장조치와 관련한 협력이 증대하고 있다. 이러한 협력으로는 우리나라 원자력 시설에 대한 IAEA 사찰, 한-IAEA 보장조치 검토회의, SAGSI 활동 등이 있으며, IAEA는 우리나라의 원자력 산업 규모와 기술 능력을 고려하여 우리나라와의 협력을 강화하고자 하고 있다. 우리나라로서는 국내 통제체제의 확립과 우리나라 원자력 활동에 대한 국제적 투명성 및 신뢰도 증진을 위하여 IAEA와의 긴밀한 협력이 필요하다. 향후 우리나라는 보장조치 의무사항의 이행 뿐 아니라, IAEA Technical Office 설치, 사찰장비의 공유, 사찰의 공동 수행, 공동연구 등을 포함한 IAEA 지원 프로그램의 추진과 같은 진보된 형태의 협력을 추진토록 하여야 할 것이다.

It is generally well known that the stratification of thermal energy in heat stores can be improved by increasing the aspect ratio (the height-to-width ratio) of the stores. Accordingly, it will be desirable to apply a high aspect ratio so as to demonstrate the good thermal performance of heat stores. However, as the aspect ratio of a store increases, the height of the store become larger compared to its width, which may be unfavorable for the structural stability of the store. Therefore, to determine an optimum aspect ratio of heat stores, a quantitative mechanical stability assessment should be performed in addition to thermal performance evaluations. In the present study, we numerically investigated the mechanical stability of silo-shaped rock caverns for underground thermal energy storage at different aspect ratios. The applied aspect ratios ranged from 1 to 6 and the mechanical stability was examined based on factor of safety using a shear strength reduction method. The results from the present study showed that the factor of safety of rock caverns tended to decrease with the increase in aspect ratio and the stress ratio of the surrounding rock mass was influential to the stability of the caverns. In addition, the numerical results demonstrated that under the same conditions of rock mass properties and aspect ratio, mechanical stability could be improved by the reduction in cavern size (storage volume), which indicates that one can design high-aspect-ratio rock caverns by dividing a single large cavern into multiple small caverns.
