최근 건설 환경의 급변화로 인해 건설 프로젝트의 실패 가능성이 높아지고 있다. 이러한 이유로 건설 산업에서는 합리적인 프로젝트 관리전략을 수립하기 위하여 프로젝트의 성과에 영향을 미치는 성공요인에 대한 다각적인 연구가 제시되고 있다. 하지만 프로젝트 성과에 영향을 미치는 요인들의 개선 여부에 따른 혼재로 합리적인 성과관리가 힘든 상황이며, 특히 개선 불가능한 요인인 프로젝트 특성은 성과에 영향을 미치는 독립변수로 성과 도출의 난이도를 결정하게 됨에도 불구하고 이에 대한 연구는 미비한 실정이다. 따라서 본 연구에서는 성과지표와 특성지표체계를 이용하여 성과와 특성간의 영향관계를 밝혀내고 그 결과를 퍼지이론으로 정량화하여 성과 난이도 지수를 산정하며 특성간의 중요도를 고려하여 최종적으로 성과 난이도를 예측하는 연구과정을 수행하였다. 또한 성과 난이도 예측에 있어서 시간과 노력을 절감하여 효율적인 프로젝트 관리 전략을 수립하기 위해서 시공자가 서로 다른 프로젝트의 특성을 입력함에 따라 프로젝트의 각 성과영역에 어떠한 난이도를 갖는지 미리 예측하고 정량적으로 평가할 수 있는 프로젝트 성과 난이도 예측 시스템을 개발하였다.

In this study, "housewives" are defined as married women who take care of housework mostly and do not work outside of home. Changing family types and higher education level of housewives enable them to be more interested in heath, beauty, and appearance. Increased interest and more frequent visits to hair salons cause scalp damage as well as hair damage, which results in hair loss. Moreover, some women suffers from scalp and hair damage due to childbirth, but many of them are not aware of it. Therefore, this study tries to find out the following; housewives' perceptions on hair and scalp management, and how such perceptions are formed. In addition, this study will present the direction for beauty marketing taking into account the characteristics of housewives and provide data necessary for them to keep their hair and scalp healthy. For these purposes, a survey was carried out after modifying the questionnaire through a presurvey. The survey tried to find 1) perceptions on hair and scalp management according to demographic characteristics, and attitude toward hair and scalp management according to demographic characteristics. Data were analyzed using frequency analysis, cross tabulation, t-test, factor analysis, and Analysis of Variance. The results were as follows, most recognize the importance of hair and scalp management but do not receive management because of the high cost, most of them receive information about hair and scalp management from people around them, and the higher the education level and health status, the more active the attitude toward hair and scalp management. These differences were all statistically significant.

There are several ways to solve parking problem in the downtown One of them is to manage parking efficiently, that is, to raise use-efficiency of parking place and to help drivers to select easily. When we manage the parking place m the block efficiently, It can prevent disproportion that some parking space is over capacity and the other parking one is under. It causes not only the disproportion of economic efficiency but also the congestion of local road. The precondition to manage parking efficiently is to analyse the parking characteristics. In this study we found out the characteristics of parking vehicles by analyzing the turnover per parking mesh and occupancy rate And we build up total D/B by collecting every information about parking space. We developed the Parking Management System by using GIS with D/B and digital map. The efficient Parking Management System is for convenience of drivers and efficient usage of parking space. And this system is also the basic study to be developed as the total Parking Management System by upgrading every information.

In real-time electricity price environment, the energy management system can provide the significant advantage to the residential, commercial and industrial customers since it can reduce the electricity charge by controlling the load operation effectively in response to time-varying price. However, the earlier studies for load management mainly focus on the residential and commercial customers except for the industrial customers because most of load operations in industrial sector are intimately related with production schedule. So, it is possible that the inappropriate control of loads in industrial sector causes huge economic loss. In this paper, therefore, we propose load control algorithm for factory energy management system(F-EMS) to achieve not only minimizing the electricity charges but also maintaining production efficiency by considering characteristics of load operation and production schedule. Considering characteristics of load operation and production schedule, the proposed load control algorithm can reflect the various characteristics of specific industrial customer and control their loads within the range that the production efficiency is maintained. Simulation results show that the proposed load control algorithm for F-EMS leads to significant reduction in the electricity charges and peak power in industrial sector.

The Purpose of the current study is to identify the differences between Samsung and Hyundai Group and the causes why the differences occurred. The study focuses on the founders of the two group as a main source of the differences, especially brain preference of the two founders. Two steps were employed to perform the study. Firstly, the two founders' characteristics were analyzed by using archival research. It was implicitly hypothesized that Group founders' characteristics explained the differences of the two Groups. It was found that the founder of Samsung Group, the late president Lee emphasized rationality, analysis, and cause/effect relationship and low risk taking, suggesting that he had left-brain preference. In contrast. the late president Chung, the founder of Hyundai Group, emphasized intuition, wholeness, contextual meaning, and risk taking, showing that he had right-brain preference. Secondly, a comparison between the two groups was performed in terms of business and financial risk in corporate portfolio, and management system. It was found that Hyundai Group was pursuing higher risk than Samsung Group. And it was observed that Samsung Group put more emphasis on formality in decision making and systematic control, and less emphasis on risk taking than Hyundai Group. From the two step research relationship between brian preference and management was reasoned. Research implications and limitations were discussed at the end of the study.

The characteristic of the water quality and pollutant discharge was analyzed at the units watershed of the total amount management in Han-river basin, and after classified in a similar area by multivariate statistical analysis, the main trend such as the water quality trend and pollutant discharge characteristic were analyzed. As a result of this study, the density of the pollutant at the unit watershed is not necessarily identified as discharge density, and the primary management watershed and targeted substances were analyzed depending on the operating status of the environmental infrastructure in watershed and the main pollution factor and discharge path per pollutants. As a result of cluster analysis, watersheds were classified into four groups according to discharge characteristics. It will be used when selecting target area of primary management that is appropriate to the characteristics of each river and establishing efficient water quality improvement plans.
