The highest fatal accident ratio was recorded in the construction industry. According to the industrial insurance premium rate & business type example, among the construction industry, the architectural work has the highest fatal and loss time accident ratio. Previous literature has investigated various aspects of accident occurrence and prevention in architectural work. However, those studied were limited in that they only focused on the fatal accident without considering the loss time accident. But non fatal accidents were recorded more than 50 times of fatal accidents. Therefore non fatal accidents must be controlled to lessen industrial accidents. Based on this, the goal of this study was to investigate the nature of the loss time accident and derive the risk index of work type in architectural work. In this study, opinions of safety experts were gathered and the risk index of work type was derived using AHP(Analytic Hierarchy Process). And verification was accomplished by comparing the results of this study with the risk index derived by analysis of accident records. Results showed that the risk index of work type was significantly higher in steel frame work, temporary installation work, earth & foundation work, facilities work, concrete work. And statistical analysis for verification showed that coefficient of Pearson correlation was 0.686 and P-value was 0.001.

본 연구에서는 현행 설계기준상의 강관말뚝머리 연결부 결합방법이 갖고 있는 전단키 용접, 철근 배근 및 정착길이 확보 등의 문제점을 개선하고자 결합용 구조 요소로 유공강판 전단연결재(Perforated Flat Shear Connector)를 활용한 새로운 보강방법을 고안하고 이에 대한 구조적 거동 특성을 실험적으로 규명하였다. 실험 결과, 유공강판 전단연결재를 활용한 보강방법은 기존 방법을 대체할 만한 동등 수준 이상의 구조 안전성은 물론 시공성 및 경제성 측면에서도 우수한 성능을 갖는 구조 시스템인 것으로 나타났으며, 이에 따라 효율적인 강관말뚝머리 연결부 보강방법의 하나로 자리매김할 것으로 기대된다.

Product liability(PL) is the producer's compensation to customers for damage incurred by product defects. This paper studies on the organizational culture, promotion process, system construction, system level, product safety review, product safety assurance, system operation, and its effectiveness and necessity of recognition for the PL system of small and medium-sized firms in Gangwon-Do province. The results show that the firms have product safety regulations, but the number of firms which its employees understand the regulations is less than the number of firms which do not understand. Also the number of firms which is preparing PL prevention and insurance, and counterplan for accidents seems to be not in large numbers.

The purpose of this study are observing changing direction of lobby space that happen by change of medical environment investigating lobby space of General Hospital by our country's medical policy change time and supply pabulum that need in forward Hospital Architecture planning. Results of this study are as follows ; Since Whole National Insurance enforcement from 1993 to 1995, form of general hospital lobby is form that outpatient entrance and inpatient entrance are detached. And lobby function divided to waiting space for medication, requisition space and also that is appearing being detached with rest space for user. ntil 1999 since 1996 that is since Medical Treatment Information System construction, the biggest characteristic of General Hospital lobby form is making Hospital Street itself do improving efficiency of flow planning being included in lobby.

최근에 기업들이 지역별 특성을 고려한 마케팅전략을 수립하기 위해 GIS를 활용하려는 시도가 이어지고 있다. 그러나 GIS 데이터의 특성상 일반 고객들이 손쉽게 접근하기 어려운 상황이다. 따라서 GIS 데이터의 한계를 극복하고 기업의 효율적인 타겟마케팅 업무지원을 위해 본 연구에서는 공간단위를 블록으로 구성하고 그 활용방안을 모색해보는 것을 목적으로 하였다. 블록의 영역을 구분한 후, 특성을 표현하기에 유의미한 인문사회적 요인으로 분류하였다. 이렇게 구성된 블록은 판매 상승 혹은 판매 하락 지역의 특성을 파악할 수 있음을 물론, 이와 유사한 블록을 추출함으로써 잠재적인 상승판매 지역을 설정하여 유형별 특성에 따른 차별화된 마케팅 전략을 수립하는데 활용 될 수 있을 것으로 판단된다.

In this study, medium capacity EHP and GHP for air-conditioning a building with a floor area of $1,200\;m^2$ are compared economically. To consider all the factors of initial and operation costs effectively, an annual equal payment method is proposed. For the initial cost, equipment, construction, installation, electric facility, financial subsidy and tax cut are considered. Basic electricity, energy(electricity and gas), space charge, labor, insurance and repair are considered for the operation cost. Under the assumptions made in this study, overall cost of EHP is less than that of GHP. However, different outcome may result if different assumptions are made. This study is useful for performing an economic evaluation of various air-conditioning systems.

One of current trends of medical technology is analog to digital. Moreover, The Government put a premium on PACS(Picture Archiving and Communication System) for Medical Insurance in November, 1999. Therefore many hospitals are installing(or planning to install) PACS facilities on their buildings. However most of hospitals didn't consider PACS facilities in the beginning of construction. In particular, the Networking is one of the most difficult things for PACS installation. There is no space for network equipments, and no path for network lines, etc. To solve these problems, wireless network is proposed. The wireless network is divided to three parts mainly. One is the wireless communication for Local Area Network, another is the data transmission through a satellite for Tele-Radiology, and the last one is the technology using Bluetooth for each sub-system of PACS. But there are other problems in wireless systems, i.e., network bandwidth, system stability, interference with other devices. The purpose of this paper is to suggest the future and new trend of PACS including all the problems.

Researchers have recently begun using high spatial resolution remote-sensing data, which are automatically captured and georeferenced, to assess damage following natural and man-made disasters, in addition to, or instead of employing the older methods of walking house-to-house for surveys, or photographing individual buildings from an airplane. This research establishes quantitative relationships between the damage states observed at ground-level, and those observed from space using high spatial resolution remote-sensing data, for windstorms, for individual site-built one- or two-family residences (FR12). "Degrees of Damage" (DOD) from the Enhanced Fujita (EF) Scale were determined for ground-based damage states; damage states were also assigned for remote-sensing imagery, using a modified version of Womble's Remote-Sensing (RS) Damage Scale. The preliminary developed model can be used to predict the ground-level damage state using remote-sensing imagery, which could significantly lessen the time and expense required to assess the damage following a windstorm.

The advantages of precast production are fast construction, reduction of labor and insurance of good quality. In recently, the application of the precast production is increased in the earth retaining wall field. This paper presents the results of the numerical modelling that was carried out to evaluate the stability of precast and prestressed earth retaining wall under dynamic train loading. The two-dimensional explicit dynamic finite element method (ABAQUS) was used to carry out the numerical analyses. The train loading to act track is calculated by using the real measured phase angle data. Mainly, the displacement and acceleration of wall structure in time domain analyzed to evaluate the stability under the dynamic train load.
