Recent projects for transferring Public Office buildings and estimation of appropriate construction expense are highly important for both government and construction firms. Moreover, estimation and management of construction expense can be regarded as extremely important duties for effective execution of a national budget as nation’s finance is invested in the Public office building projects progressed by the government. To progress one project for Public office building, not only the organization demanding the project but also an investment screening organization, a budget-managing organization, a feasibility assessment institution and many other related organizations participate in the project and a lot of decisions arisen from the project operation are made on the basis of construction expenses calculated for relevant stages. And estimation of rational construction expense is also critical for designers in order to create design within the fixed budget simultaneously with securing the quality and efficiency of structures to the maximum. Therefore this research suggested an improvement process to analyze problems in current construction expense management process and to administer the construction expenses effectively.

This paper deals with the construction of system for correct location determination of fixed tag. We adapted to construct the above method. Also we adapted the several filtering method.

Recently, carelessness on safety management in construction sites has caused a sharper upward trend in accidents and disasters, compared to the past. Therefore, this study analyzes the causes of accidents that occurred on construction sites in the year of 2007, and proposes preventive measures. The construction industry had a heavy death rate with 279 out of 418 deaths from falls in all industrial sites, accounting for 66.7%. And the causation analysis found a particularly high incidence of temporary structure-related accidents, with falling off scaffolding as the most common cause of accidents. According to the causation analysis of fall-down accident cases, accidents induced by protrusion on construction sites are a big contributor resulting in the deaths of 312, accounting for 74.8%, which is deemed to be due to site disorderliness. And to remove floor protrusions and to secure workers' traffic line and safety, neat and thorough site arrangement is necessary. Against collision, efforts must be made to prevent equipment-pedestrian crashes on site, which necessarily requires emergency lamps, alarm bells, and safety poles and blocks to be installed, lighting systems to be improved, obstacles to be removed, site supervisors to be assigned to construction equipment works, and workers to be more intensely trained and supervised.

This study aims to classify the architectural formation of the Stylobate of and Staircase types of Post-Lintel Construction in Backje style and Silla style and also to figure out their specific elements by periods and transformation characteristics. The scope of this study was restricted to architectural remains between the Three Kingdom period and the Goryeo period. To progress the investigation, the study classified remains in a similar type by period and type, and then and analyzed its character based on formation method and specific factors of subsidiary materials. As a result, its type can be classified as Backje type(Ⅰ), Silla type(Ⅱ) and Mixed type(Ⅲ). Regionally, it is found that Woongjin, Sabi and surroundings in the capital of Backje, Gyeongju and main towns in the capital of Silla, and Gaeseong and main towns in the capital of Goryeo. In particular, type III has the characteristics of type I and II simultaneously, which has one or two layers Jangdaeseok stone between the foundation stone of stylobate and plate stone, and tends to be decorative when Taengjuseok stone is installed. For types of staircase, it could be classified as 6~7C Backje type(Ⅰ), 7~9C Silla type(Ⅱ) and 9C Mixed type(Ⅲ) according to the formation method of Somaetdol (banister of stone stair). And from the 9th century on, decorated Somaetdol stone type(IV) of 1/4 circle shape began to appear. The common feature of stylobate of post-lintel and staircase is that it became simplified, abbreviated and decorative. It seems to be intended to secure simplicity of construction or structural stability.

This paper explores the dynamic construction of expert and novice identities in language-exchange conversations between Korean students learning English and American students learning Korean. Drawing on recent view on identity as performance (Butler, 1990), this study employs video- and audio-recordings of language-exchange interactions to examine the dialogic interaction between three language-exchange pairs. Adopting a conversation analytic perspective, the study examines whether and how participants of language-exchange interactions orient to their assumed roles as peer-teacher and peer-learner during language-exchange through micro-analysis of the interaction. The findings demonstrate that participant roles as linguistic expert and novice are not invoked in language-exchange interactions unless they arc treated as relevant in the interaction; rather than foregrounded by the situational arrangements of language-exchange, the expert-novice relationship in language-exchange dialogues is interactionally constituted by the local practices of the participants. Data analysis also shows that the construction of expert and novice identities in language-exchange interaction is a jointly constructed achievement and that participant roles as language expert and novice arc not given but ‘achieved’ as language-exchange participants ratify or reject the identity their partners display in the course of unfolding interaction.

We constructed two test server systems for KMTNet data management. One is the photometry database server which is optimized for stable operation, and the other is the photometric data process server which is optimized for fast I/O between devices. The performances of servers and data storage units were tested using various methods. Database upload was also checked using five different methods. From tests, we concluded that the most efficient method to upload photometric data processing results to database is the use of three nodes with job scheduler under the InnoDB engine. In this study we provide the test results for prototype servers for KMTNet data management.

The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

울산광역시 울주군 서생면 서생리 진하해수욕장 서편 야산 구릉에 위치한 서생포왜성(西生浦倭城)은 임진왜란 시기에 가토 기요마사(加藤淸正)에 의해 축성되었다. 서생포왜성은 남․동해안 각지에 현존하는 30여개의 왜성 가운데 보존상태가 가장 뛰어나 왜성 연구의 최적지가 되고 있으며 임란 중 사명대사가 가토 기요마사와 4차례에 걸친 평화교섭을 진행하여 많은 외교적 성과를 거둔 역사적 장소이기도 하다. 또한 임진왜란 직후부터 1895년까지 약 300년 동안 조선 수군(水軍)의 동첨절제사영(同僉節制使營)으로 사용되었기에 근세기 한일간 축성법의 비교연구뿐만 아니라 성곽이용방식에 대한 상호 고찰도 가능하다. 이에 본 연구는 지금까지 주로 일본인 학자들에 의해 연구가 진행되었던 서생포왜성에 대한 조사연구를 진행함으로써 일차적으로는 왜성의 성곽구조와 체성 축조기법상의 특성을 밝히고 이차적으로 한국성곽과의 비교연구를 위한 기초 자료를 제공하고자 하였다. 연구방법으로는 일차적으로 문헌조사를 실시하고 이를 토대로 현장실측조사를 진행하였다. 그 결과 입지 및 평면형태, 성곽 내부의 공간구조, 虎口와 해자 등의 방어시설물, 체성 및 隅角部축조수법, 성벽의 기울기 등 서생포왜성의 제반 특성을 이해할 수 있게 되었다.
