Most construction works in a building site are progressed by many work categories and sub-contractors. Therefore there are many difficult things of management of construction-information because variable occurrences are happened to manpower and material resources. For this reason, various management systems are suggested, but the application of these systems are difficult because only construction company manages these systems and sub-contractor's participation, understanding and financial ability are insufficient. In addition to that, there are other problems such as lost information when it is carried, perversion and distrust of information by hand and lots of time and labor are necessary for collection, analysis, and management of information which are offered for daily report. so the purpose of this study is for improvement of reporting process with making an analysis of productivity effects and an analysis of function and problem of daily report. I intend to suggest the direction of improved daily report system for better productivity of construction work through input information and management of cooperation enterprises.

Building construction projects are performed by a number of sub-contractors specialized in diverse trades. Therefore information management among these constituents is quite challenging especially due to exponentially increasing manpower and material resources. In recognition of the importance of information management in project sites a number of systems have been suggested, but the application is limited one of the main reason is that general contractors use these systems and sub-contractor's participation understanding and financial ability are limited. Besides other problems such as loss along communication channel, distortion of information due to inefficient input device and tremendous amount of time and labor are required for collection analysis, and management of information to prepare a daily-report. Therefore the Purpose of this study is to improve reporting process through analyzing current daily reporting system. This paper also suggests the direction of the improved daily reporting system to enhance the performance of construction projects through incorporating sub-contractor's participation in daily reporting system.

다품종 소량 생산으로 제조 업체의 전산 업무 관리가 매우 복잡해지고 있고, 전산 시스템이 급속히 변하며 환경이 복잡해지고 있으며. 전산에 입력해야 할 데이터들은 많아지고 있다 그래서 제조 업체의 근태 및 입출고 전표, 작업 일보 데이터를 사람이 일일이 입력하기엔 많은 전산 단말기와 용량이 큰 시스템을 요구하고 있으며, 현장 데이터의 실시간 처리 및 확인이 어려운 상태이다. 본 논문에서 제안된 P.O.P(Point Of Production) 단말기를 이용한 생산통신관리 시스템은 제조 업체 현장에 P.O.P 단말기를 설치하여 현장에서 일어나는 모든 입출고 및 생산 데이터를 생산 시점에서 입력 할 수 있는 기능을 가진 시스템을 설계하고 구현한다.

건설 프로젝트 관리의 주요한 목표는 계획된 시간 내에, 정해진 예산으로 규정된 목표(명세 또는 품질)를 확보하는 것이다. 국내 건설 산업은 타 산업 분야에 비하여 생산성이 매우 낮은 편이다. 이는 60년대 이후 급속한 개발 정책에 따른 부작용의 하나로, 하드웨어의 급속한 성장에 비하여 이를 관리하기 위한 소프트웨어의 개발이 부족했기 때문으로 풀이할 수 있다. 이에 본 연구에서는 건설 프로젝트의 생산성을 향상시키기 위한 노력의 일환으로 계획 단계에서의 실행과 완성 단계에서의 실행을 비교하여 이를 작업일보, 감독일지 등의 진도관리 자료를 활용하여 분석하여 건설 프로젝트의 실제적인 생산성 저하 요인을 도출하였다. 따라서 본 연구 결과는 현행 국내의 건설 프로젝트에 대한 사례분석을 통하여 실제적인 생산성 저하 요인을 분석한 것인 만큼 향후 건설 관리 기술의 향상에 많은 도움을 줄 수 있을 것으로 기대된다.

A production management system is developed to enhance both the information and productivity of ship and offshore plant deckhouse floor outfitting. The functions of the production management system for the deckhouse floor outfitting were reviewed based on a literature survey of several production management systems with respect to the ship building and architecture fields. This study investigated numerous daily production reports and their application to actual work places to utilize the system development. The developed scanned drawing-based production management (SDPM) system minimizes any loss and/or distortion of work information between the workshop and management office when applying a scanned production drawing to the daily report. The SDPM system increases the data objectivity, as well as intuitiveness of the information generation by adopting an efficient user interface, which makes it possible to perform image annotations on the scanned drawing for the daily production report while simultaneously interacting with the production management database. Applying the system operation to actual deckhouse floor covering work verified that it was feasible to use the SDPM system for production management in the ship outfitting work process.

Change is inevitable and is a reality of construction projects. Change adjustment includes the cost associated with materials, labor, etc. However, the actions of a contractor can cause a loss of productivity and furthermore can result in disruption of the whole project because of a cumulative or ripple effect. Because of its complicated nature, it becomes a complex issue to determine the cumulative impact (ripple effect) caused by single or multiple change orders. Furthermore, owners and contractors do not always agree on the adjusted contract price for the cumulative impact of the changes. What is needed is a reliable method to identify and quantify the loss of productivity caused by cumulative impact of change orders. This study survey the change orders data in domestic area for public construction and analyze to quantify change order impact. This study developed concepts of "%CO", "%Delta", "%T" to capture change order effect on project and search the relationships between them. Finally, this study find strong relationship between change order and loss.

The major purpose of construction project management is to meet defined targets(scope or quality) on schedule and budget. Korean construction industry is suuering from lower productivity as compared to other industry sectors. 'Management software' of the construction industry has not been developed as fast as hardware in the aftermath of compressed economic development following the Korean War. Therefore, this study is intended to compare project execution at planning phase and at completion phase and identifying the risk factor of construction projects. Construction projects are more extensive and long-winding than any other projects and stake holders of complex interests are often involved. In this study, we identified and analyzed risk factor for domestic building construction projects and outputs of this study will be conducive to the improvement of construction management processes in the future.

This study interprets Cheong-gye-cheon restoration as a process of space production during expansion of capitalism, and performs discourse analysis in order to find out that how media discourse has been related to the production of Cheong-gye-cheon space in each period of historical changes. This paper is particularly concentrating on discovering regulation in discourse which connects people's experiences and perception towards certain ways in the relationship between newly producted space and media discourse. This paper construes the period of 1960s as a process which pre-modern bodies and facilities were changed into modern and urban 'daily life' by practicing a space which splitted in a concept of time efficiency. In 1980s, media represented the facilities which had been constructed at the Cheong-gye-cheon space as a 'disqualified facilities for a center of the city'. This is because, tertiary industries were emerged at the 'Gang-nam' in this period which widen the gap of finance between 'Gang-nam' and 'Gang-Buk'. The government wanted to redevelop this space in order to function accumulating capital efficiently. Therefore shop owners nearby Cheong-gye-cheon were forced to move out. The discourse, 'disqualified facilities for a center of the city', implicates this process. The media discourse in the 2000s produced the 'myth' through the 'signifier' such as artificially flowing water, fine scenery, historical but artificial structure and etc.. However, people can experience symbols of the artificial structures which leads people to the luxurious restaurants, coffee shops, and etc.. Naturally, the spectacles produced by media direct people to the homogeneous pattern of consume. This phenomena can be explained as a process which people practice, intentionally or non-intentionally, the capitalistic mode of production which changed from a period of production to a period of consumption.
