The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.

The purpose of this study is to suggest improvement of certification standards of environment friendly architecture in ecological environment field by surveying and analyzing actual status of actual certification schools of environment friendly architecture per ecological environment elements through extracting ecological environment elements which is possible to analyze in quantity certification standards of environment friendly architecture. As contents of the study, first, certification as an examination on certification system of environment friendly architecture, summary of certification system of environment friendly architecture, ecological environment elements which is possible for quantitative analysis of ecological environment certification standards were extracted. Second, actual status of ecological environment elements per school grade, region, and population increase by collecting actual data of certification schools of environment friendly architecture. Third, using analysis data of ecological environment elements, ecological area ratio of certification schools of environment friendly architecture per weighted values of space types was calculated and the results were analyzed as the follows. (1) In case of preliminary certification out of total objects of investigation schools was average 34.06% but in this case of certification, it was reduced to 33.07%. However, it is difficult to make judgment as actual evidence data since ecological area ratio of actual preliminary certification is data based on drawing planes. Therefore, in case of this certification, elementary schools was investigated at average 33.11%, middle schools 34.81%, and high schools 31.28% and middle school showed the highest relatively. (2) Besides, average composition ratio of ecological area ratio was 63.04% in case of this certification regardless of school grade and region and it was analyzed that about 70% of ecological area ratio is composed of the natural based green area including pure natural based green land and 6.89% of ecological learning institute.

The purpose of the study of multi-robot system is to realize multi-robot system easy for the control of robot system in case robot is adapted in the complicated environment of task structure. The purpose of the study of multi-robot system is to realize multi-robot system easy for the control of robot system in case robot is adapted in the complicated environment of task structure. To make real time control possible by making effective use of recognized information in this dynamic environment, suitable distribution of tasks should be made in consideration of function and role of each performing robots. In this paper, IHMA (Intelligent Hybrid Modular Architecture) of Intelligent combined control architecture which utilizes the merits of deliberative and reactive controllers will be suggested and its efficiency will be evaluated through the adaptation of control architecture to representative multi-robot system.

It has found that the using library base on criteria of a foreign country resulted in problem of reliability. In order to obtain reliable result, it was necessary to develop the simulation input library based on domestic condition. So, this study was conducted for making the library in accordance with domestic condition when doing simulation modeling about the exist and new buildings. The range of library were consist of material, facility systems, schedules and weather data. And Energy Plus program was used when making library. We hope that the developed library will contribute to reliability when simulating exist and new buildings.

Honeynets have become one of essential tools in system and network security. As the importance of security has increased over the years, many researchers try to improve the overall Honeynet architecture. Due to their efforts, the Honeynets have evolved up to the third generation. However, the GenIII architecture has some limitations. In this paper, we address some of the limitations and provide solutions by redesigning the framework of data capture of Honeynets.

2000년대는 7차 교육과정에 따른 교과교실제의 적용, BTL사업의 시행 등 학교 건축에 영향을 미치는 교육시설정책상의 변화가 나타났던 시기였다. 특히 '열린교실'이라는 키워드가 있었던 초등학교와 달리 '교과교실'이라는 새로운 키워드가 등장했던 중등학교에서는 새로운 학교건축의 출현이 기대되던 시기이기도 하다. 따라서 2000년대 중등학교 건축은 주목하여 살펴볼 필요가 있다. 이에 본 연구는 일차적으로 2000년대 중학교 건축을 대상으로 그 건축적 특성을 살펴보고자 하였다. 이를 위해 에듀맥의 '우수학교 설계자료집'에 소개된 18개 중학교들을 대상으로 배치계획과 각 영역별 계획특성을 분석하였고 이를 종합하여 2000년대 중학교 건축에 나타나는 계획특성을 정리하고 개선점을 제시하였다. 분석결과 사례대상교들은 단위교실, 블록플랜 등의 계획영역에서 기존 학교건축의 전형적 특성인 남향위주의 계획방식이 유지되는 가운데 교사동 내외부의 공간구성은 다양해졌으며, 시설구성도 충실해진 특성을 보였다. 하지만 도시건축적 특성이나 전통성, 지역성 등의 표현 그리고 새로운 학교건축을 제안하기 위한 실험에서는 적극적이지 못했던 한계도 갖는다.

An architectural practice cannot help involving a social art as its own concept. Especially school buildings are subjected to the influence of not only the educational philosophy and the national curriculum, but also the sociocultural context with the change of the times. This study aims to explore the contemporary trends of school architecture and give new inspiration to the school design practice. After it establishes the 'contemporary' school architecture as school buildings built from the second half of the 1980's to the present time, this paper classifies them into 4 categories : popularist trend, traditional and regional tendency, revival of classicism and the pursuit of art for art's sake.
