건설산업의 경쟁력 제고를 위해 건설산업에서 기획${\cdot}$설계${\cdot}$시공${\cdot}$사후관리단계에서 엔지니어링분야에 대한 고도의 기술력과 함께 이들을 총체적으로 관리할 수 있는 사업관리능력의 향상이 매우 중요하다. 최근 SOC사업이 대형화, 복잡화됨에 따라 전문 기술과 경험을 보유한 전문 건설사업관리 인력이 필요하고, 대형 사업의 사업관리수행방법의 형태가 발주 직영에서 사업관리 대리인인 CMr 체계로 바뀌어 가고 있다. 이와 같은 배경아래 대형 민자유치사업의 성공적인 수행을 위해서는 통합 CM/PM능력을 구비한 전략적 건설수행체제 구축이 필요하며, 이를 통해 사업비의 감소와 공기단축을 이루어 궁극적으로는 국내 건설업체의 경쟁력강화와 전문화/특화화를 이룰 수 있을 것이다. 이를 위해 본고에서는 민자사업에서의 CM의 역활을 중점적으로 논하고져 한다.

Today the domestic construction industries are changing. The bigger, higher and more professional are gradually the construction industries, the faster does the fusion into the other industries also undergone. It is gradually needed to estimate the process of the project in the construction industries through this tendency. Consumers or the owner gradually reify their needs and it is essential for an objective appraisal standard to estimate the accomplishment of the project because its level is raised. In this study the problem is understood through the analysis on the existing system of construction industries and it is indicated to new performance measurement system in construction project through the analysis on the influential factors including the qualitative analysis such as consumer satisfaction.

Environmental impact assessment is a regulation that is implemented to reduce harmful environmental impacts of development projects. However, The environmental value is difficult to quantify and the uncertainty, There is a problem of objectivity and reliability of the system is consistently pointed out. Therefore, the necessity of the data-based environmental impact assessment system is gradually increasing. Especially, environmental impact assessment is highly applicable to environmental spatial information because it contains about the development of a particular area. Also with the introduction of EIA Follow-up management system, there is a demand for a system for providing and utilizing environmental information in a time series. This study derives the necessity of information provision system and analyz existing environmental information utilization system based on the institutional characteristics of environmental impact assessment. And suggest ways to provide environmental spatial information to find policy implications for improving the limit of environmental impact assessment system.

Road construction projects have a long duration so cost overruns and schedule delays are occurred. However, performance assessment system that can manage and prepare for this in advance is insufficient. In addition, road construction are affected by many factors during under construction. Therefore it is necessary to conduct performance assessment considering the characteristics of roads and prepare for similar projects in the future. The purpose of this study is to provide a framework to evaluate construction phase performance and present a performance management plan using road construction information. Also, This study conducted time adjustment between the start and the finish of the project and developed performance metrics based on absolute and relative indicator. This study analyzed the cost, schedule, and changes of the road project construction process, showing the possibility of advancement of performance assessment and how to use it when planning new road construction projects.

우리나라에서도 정보 보안에 관한 인식이 이젠 과거와는 달리 많이 높아지고 있는 실정이며, 그래서 과거의 시스템 구축만으로 보안을 끝이라고 아는 인식보다는 보안의 사후 지속적인 관리가 더 중요하다고 인식하는 사례가 증가하고 있는 실정이다. 이에따라 구축해 놓은 보안 시스템을 24시간 감시해주고 모니터링 해주는 관제서비스 분야가 서서히 두각을 나타내고 있다.

Accuracy control of Linear accelerator installed in OBI is done daily and weekly and importance of accuracy multiplies exponentially at that moment. Purpose of this experiment is everyday and twice a week over a four month period (march~june) 2009 year to confirm maintenance of accuracy through Quality control of OBI. In short, measurement of exponentially multiplying accuracy of OBI and regular accuracy control was able to maintain accuracy from the center of treatment within 0.1 cm. Therefore, evaluation of exponentially multiplying accuracy using OBI accuracy control linear accelerator phantom on daily, weekly basis was confirmed.

The purpose of this study is to develop an emotional management program on adolescents' happiness and psychological well-being. The participants were 100 students from two middle schools located in Seoul. Half of them were assigned to the treatment group, and the other half were assigned to the control group. Students in the treatment group participated in an emotional management program for 8 weeks. All of the participants' happiness and psychological well-being scores were measured before and after implementation of the program. The pre-test scores of both groups indicated that they were homogeneous. However, as for the post-test, the happiness score of the treatment group was significantly higher than that of the control group. Also, the scores of the treatment group on six subdimensions of psychological well-being were higher than those of the control group. These results imply that the emotional management program has a significant, positive effect on adolescents' happiness and psychological well-being.
