Recently, the importance of Pre-construction is gradually increasing in construction business. In addition to increasing greatness, Pre-construction affect to success or failure of projects. However, current domestic construction business doesn't constitute exact concepts and systems, and there are a lot of problems such as disorganize management of construction because most of Pre-construction depends on supervisors' experiences. Therefore, according as doing this study, We are going to analyze the tendency of Pre-construction step and bring up designed operation systems between departments in construction company. So we can expect to develop efficiency by excluding unnecessary operation and formulating more improved operation process.

The Ministry of Construction and Transportation has estimated the reconsideration of economy in construction and the dullness of LCC forcast method which supports decision-marking in safety and maintenance of buildings. So, they have introduced LCC analysis method in steps of a feasibility study and design. Because of the introduction of LCC analysis process and method, it would be possible to make a logical decision from management maintenance, estimation, user point of view. In this study, it would bepossible to show a plan and alternative of design factors and structure in one building by using LCC analysis method and to compare and analyze the reduction of life circle cost bi the elapsed time.

Government legislates a private sector preparedness act related to disasters such as natural, technological, and social ones. According to the law, it announces new standard for private sector preparedness. This paper illustrates a mitigation action plan based on the standard in terms of a cyber disaster. This plan includes organization, policy, assessment, impact analysis, strategy, plan, action, evaluation, and feedback. It will also help for business to mitigate a cyber disaster. Private sector accreditation and certification preparedness program which introduces on the law is the realization that enterprise disaster management will be expected as a great tipping-point.

이 논문은 Minnesota대학 Paul Campus 도서관 부관장인 존슨(P. Johnson)이 Journal of Academic Libraianship, Vol. 16, No. 4(Sept, 1990), pp.222-229에 게재한 "Matrix Management: An Organizational Alternative for Libraries"을 완역한 것으로, 도서관의 전통적인 조직구조에 대한 대안을 모색하는데 참고할 수 있는 이론적 논문으로 사료됨. 도서관조직구조가 점점 복잡해 짐에 따라 다양한 방안들을 모색하여 왔다. 이 논문은 전통적 계층구조에 대한 대안으로서의 매트릭스구조의 효용에 관하여 논의 한 것이다. 매트릭스관리가 매우 성공적으로 이루어질 경우에는 사서들에게 유연성을 증대시키기 위한 신전략과 고도의 전문적 독립성, 그리고 보다 균형된 의사결정과정을 제공해 준다. 제2차 세계대전까지만 해도 도서관을 포함한 대다수 기관의 조직구조는 몇 가지로 나눌 수 있었다. 비록 이들 조직구조가 바뀌게 되었다 하더라도 그것은 의도적인 계획하에서 진전된 것이 아니라 안정적이고 예측가능한 환경에 매우 적합하도록 자연스럽게 이루어진 것이다. 다만 최근 여러 해 동안 급격한 환경변화로 인하여 보다 새로운 조직구조가 발전하게 되었는데, 이는 자연진화적인 조직변화라기 보다는 오히려 특정적 요구를 충족시키기 위한 자의적인 계획의 결과라고 하겠다. 이와 같은 급격한 변화에 대처하도록 특별히 계획된 매우 혁신적인 조직구조중의 하나가 조직매트릭스이다. 이 논문은 대학도서관에 있어서 조직구조, 조직대안으로서의 매트릭스구조, 매트릭스경영관리의 효용 등 세 가지의 문제에 대하여 고찰하고자 한다.<역자주>

In this paper, a linear programming was used for determining the optimum efficiency required of each wastwater treatment facility and minimum total treatment casts in order to meet any set of stream dissolved oxygen standards within a river basin. The optimum solution of water quality control which was obtained with the inventory equation of Camp-Dobbins' equation incorporated into the constraints of linear programming was compared with that of Streeter-Phelps' equation. It can be concluded that correlation coefficient was 0.997. Then the linear programming incorporating the inventory equation of selected streeter-Phelps equation was used in order to obtain the optimum solution of water quality control based on data form the Nakdong River.

This study developed a ten-step procedure of integrated watershed management (IWM) for sustainability to rehabilitate the distorted hydrologic cycle and identified spatial hazard ranking(step 2). Spatial hazard indices, Potential flood damage (PFD), potential streamflow depletion (PSD), potential water quality deterioration (PWQD), and watershed evaluation index (WEI) were developed using multi-criteria decision making (MCDM) techniques and sustainability evaluation concept(pressure-state-response model). The used MCDM techniques are composite programming, compromise programing, Regime method, and EVAMIX approach which are classified by data availability and objectives (prefeasibility and feasibility).

Company needs information management activities for establishing the R&D plans and for working out countermeasures against changes of environment which threaten the management. Nowadays the quantity of information to be gathered is increasing and uncertainties in decision making are also increasing, so the importance of the systematic activities for information are highly recogniyed In this paper, information management method that can be useful for some companies are suggested. Most of information management division in small & medium sized organizations have problems with respect to information analysis. In this study solutions for those problems ane also suggested.

PPC stands for the percentage of weekly assignments completed. It makes it possible to improve the performance of production planning and control systems. Recently, the cases of PPC application have been increasing because PPC is easy to apply to construction site. However, to evaluate the average of PPC or analyze PPC as time passes has some problem ; if PPC is the same, the average it is evaluated equally although there are variabilities in production system. Therefore, In order to evaluate the character of PPC in process of production this paper suggests the method of the evaluating PPC by using coefficient of variability besides PPC measurement.

유역통합관리 계획 수립시 하천의 현재 뿐만 아니라 미래에 대한 환경변화도 고려되어야 한다. 즉, 하천 유역에 발생될 미래의 강우량과 토지이용변화, 인구 증가 등도 종합적으로 고려하여 유역통합관리 계획을 마련하여야 한다. 본 연구에서는 미래의 환경변화를 고려한 유역통합관리 계획의 기초 연구로서, 미래의 기후변화 및 토지이용변화 시나리오에 따른 목감천 유역의 유출특성을 분석하였다. 즉, 목감천 유역의 장기유출모의를 2020년~2039년의 20년 동안의 수행하였다. 이때 기후변화 시나리오는 GCM의 A1B, A2를 사용하였고 토지이용변화 시나리오는 ICM의 3단계, 즉, 불투수면적이 변하지 않는 경우(Case 1), 1 단계 증가하는 경우(Case 2), 2단계 증가하는 경우(Case 3)를 고려하였다. 모의 결과를 살펴보면, A1B의 기후변화 시나리오를 이용하였을 경우 최대 유출량은 $177m^3/s{\sim}190m^3/s$이 발생되며, 토지이용변화에 따른 유출 증가율은 Case 1에서 Case 2으로 변할 경우 1.7%, Case 2에서 Case 3으로 변할 경우 5.3% 증가하는 것으로 나타났다. 또한 A2의 기후변화 시나리오를 이용하였을 경우 최대 유출량은 $167m^3/s{\sim}173m^3/s$이 발생되며, 토지이용변화에 따른 유출 증가율은 Case 1에서 Case 2으로 변할 경우 1.2%, Case 2에서 Case 3으로 변할 경우 2.3% 증가하는 것으로 나타났다.
