The purpose of this study is to suggest an Improvement Model of defect information management system. The improvement model adapts methods for the residents to input defect information correctly and share to defect information with construction company. The adapted research method is review for existing defect information management system and suggested for data flow diagram of improvement model. The results of this study are as follows: The basic design of the information input window of the defect information management system for connecting with big data was made. And 5 point scale was applied to evaluate the convenience, simplicity, accuracy, necessity, and usability of the improvement model. It is evaluated that the economic effect caused by using the improvement model is saved by about 151 million KRW compared to the existing method. The Improvement model is used utilize big data in correct defect management and decision making.

This study aims at the development of a cost management system in building interior projects. Renovation and remodeling is activated and expanded much more being compared with new building construction at present. After Interior project proceeding must get out of simple estimate and assumption, then its be needed a formal work process and computerized cost management. Proceeding a building interior project management was proceed in the office and the field. Cost break down, especially, depend on the field manger and used fiend managing money because its not checked by cost manager in office manger. For this study, cost factors are defined in terms of cost break-down interior works which consist of materials and labors. A data model for cost factors was developed, and a relational database is used to realize cost data management based upon this data model. Data input and output are achieved by internet from both of wired PC and mobile phone. This system can timely display a number of needed reports for cost management that identifies cash flow and predicts budget for cost break-down works in interior projects.

This paper reviews four factors involved in apparel and textile manufacturing procedures under international economic fluctuation. This work will be helpful to evaluate the efficiency of global manufacturing systems. Production costs including direct costs related to material and labor costs, and indirect costs associated with manufacturing running ones are significantly correlated to diverse visible and invisible elements such as infrastructure and the labor skills of foreign manufacturing areas, which might create an apparent difference in production costs. Manufacturers can consider how to improve the efficiency of manufacturing systems through a review of the co-relationship between manufacturing procedures and four factors such as manufacturing systems, production outsourcing types, manufacturing locations, and production costs in detail. In addition, the four factors are the core parameters of determining or contributing to the efficiency of a production schedule that is ultimately associated with the supply chain management (SCM) to efficiently conduct Quick Response (QR).

As worldwide efforts to reduce global warming gases, the construction Industry is endeavoring to diminish carbon dioxides emissions. Especially, by introducing the LCA methodology to the industry, A variety of related studies to measure the emission of carbon dioxides have been conducted. However, when the conventional LCA methodology is applied to the construction projects, some limitations have been reported. To overcome the restrictions derived from the industry characteristics, this research suggested the Activity-based LCA model by applying the Activity-based Costing (ABC), which breaks down the whole life cycles into more detailed stages. By implementing the newly developed model, forecasting accuracy of $CO_2$ emission was elevated, and the critical control points on carbon dioxides were established. Through the case study of aluminium curtain-wall system, this research verified the usefulness of the Activity-based LCA.

오늘날 노사분규로 인한 인건비 상승, 무역마찰등의 경제환경이 변화하고 시장환경의 특성이 다품종소량생산, 시장다변화에 따른 생산계획의 빈번한 변화, Life Cycle의 단축, 단납기화, 품질의 고신뢰성 등의 추세를 따르고 있어 이에 대응하기 위해서는 생산기술과 관리기술면에서 일대 혁신이 필요합니다. 자재, 공정, 설비, 재고, 원가, 납기등을 유기적으로 연결하고 이를 하나의 체계로 관리함으로써 얻을 수 있는 생산성의 향상은 생산기술의 진보에 의하여 얻어지는 것에 비해 결코 적지않을 것입니다. 또한 생산자동화를 위한 선행조건 으로 제조관리 업무의 개선이 필요하므로 제조관리의 중요성은 아무리 강조하여도 지나침이 없다.

In this study, the project manager-oriented organization model has been verified by analysing it with forming a clear definition of detailed unitary duty entity to develop current non-efficient CM system constituted by functional organization with the decentralized responsibility and apply the model As a result from verification that the model provides valid solutions by comparing it with the existing, the model is better than the existing in cost savings, target profit sales rate, total rate of new on sales. Moreover, various activities in cost savings and cases where improvement is feasible are executed. However, the model caused some problems in organizational operation, project management and in division of duties so this study proposed improving management method

시간과 공간의 제약이 사라지고 지구촌이 하나의 세상으로 발전하고 있다. 정보가 힘이 되는 세상에 고객의 요구에 부흥하는 기업만이 살아 남을 수 있으며 고객의 성향 및 기호에 부흥하는 상품을 개발하고 철저한 원가 분석에 의한 과학적인 경영만이 기업의 생존을 보장하는 세상이 되었다. 이 글에서는 IMF 이후에 개방화의 물결 및 구조 조정이라는 거대한 파도를 맞은 금융권의 선진 분석시스템의 구축사례를 소개하고자 한다. 광주은행에서는 과학적 금융 기법을 습득하여 불필요한 낭비 요소를 줄이고자 하며, OFSA를 이용하여 위험관리시스템을 구축함으로써 내부 역량을 축적하고 새로운 도약의 발판을 마련하려 노력하고 있다.
