우리나라 건설시장 및 설계시장의 규모에 대비하여 저작권에 대한 인식이 부족하며 건축물 저작권에 대하여 현실적으로 인정되는 부분도 제한적이다. 사상 또는 감정을 표현한 창작물로서 건축 저작물이 보호를 받는 것은 창작성이 인정되는 전체적인 디자인이고 개개의 구성요소는 보호 받기 어렵다. 건설업체들이 건축물 저작권을 등록하고 브랜드의 독특한 창작물임을 보호 받고자 하나，현실적으로는 의장등록 등을 통해서 보호 받으며 저작권은 마케팅 목적 등 차별화를 위하여 등록하는 실정이다. 멀티미디어 환경은 전통적인 지적소유권 보호에 관한 법리로 해결하기 어려운 새로운 문제들을 발생시키고 있으므로 이에 대응하기 위하여 지적소유권 법체계도 변화를 요구 받고 있으며，저작권을 제대로 인정받 기 위해서는 저작권에 대한 범위를 일반화 할 필요성이 있다.

The occupational safety and health expenses in construction since 1988 has contributed significantly to the reduction of injury occurrence rate. But accounted basis and criteria used of the occupational safety and health expenses have been pointed out so many issues. The purpose of this study, perform analysis of the effectiveness of the occupational safety and health expenses through the reviewing of several issues about the current system and analysis of existing statistical data. Based on the result of the research, it is concluded that the contribution survey of the occupational safety and health expenses on the safety accident prevention program qualitatively evaluated as an average of 4.39(standard deviatin 0.652) on the five point scale based was very positive.

본 연구는 부산 신항만 건설전․후 가덕도 주변해역의 수리환경 변화를 살펴보기 위해 부산 신항과 낙동강 하구역을 포함하는 가덕도 주변 해역에 대한 2002년부터 2009년까지의 수질 관측 자료를 바탕으로 신항 개발에 따른 수질환경의 경년 변화를 살펴보았다. 또한 신항 건 설전․후에 대한 수심적분 해수유동모형을 구축하고 이를 통해 부산 신항만 건설(완공 전․후)로 인한 평균대조기 조건에서의 해수유동장을 재 현하고 가덕도 주변해역에 해당하는 부산 신항만과 낙동강 하구역의 두 해역간 유출입되는 단면 Net-flux의 수치실험을 통해 해수수송량을 해석하였다.

This is to show some basic data for introducing both circulated aggregate and recycled powder producing waste concrete. Standard-mixing design for 24MPa has been basically used and added and replaced normal aggregate with recycled powder made of waste concrete. In addition, polycarboxylate high-range water reducing agent has been used because recycled powder is missing adhesive strength and it is not compare with cement's adhesive strength. Compressive strength with powder mixture of 2%, 4%, 6%, 8%, and 10% has been decreased down to 80% of normal concrete material strength without recycled powder mixture. 200℃, 400℃ and 600℃ heated concrete were compressively tested in order to find out concrete strength resistant to high temperature. heat capacity was also tested, based on the expectancy of its low conductivity. In addition, thermal conduction test was tested in order to find out concrete insulation. According to this test, when concrete was tested by fire resistance, it using the circulation aggregate was same resulted by concrete using the natural aggregate. also, recycle powder was not effecting insulation performance. but it is fit to standard on concrete insulation of building law.

Risk level for each construction work can be very important factors to establish advanced prevention measures. But it is important how to produce it. There are three different methods to set it up for construction situation. They are as follows; 1) occurrence frequency = the number of accident workers of each work kind / yearly accident workers 2) occurrence frequency = the number of accident workers of each work kind / yearly workers 3) occurrence frequency = the number of accident workers of each work kind / the total workers All these three concepts(=averaged concept)are analyzed. Additionally frequency based on discrete curve, and severity based on continuous curve are also combined for producing risk level with more scientific approach. This risk level can be very useful to make prevention plan or take measures at construction sites. This is study result can change existing risk level concept to new concept of it, namely rail way work and in-water work showed be high risk level and RC work be low risk level, different from the situation which we have thought commonly, so far.

Establishing a framework, to explain the path to safety accidents considering major safety management factors such as physical conditions including on-site activities and workplace, as well as human factors as to labor, supervisors, or managers, would be effective as the basis to control project's risks by preventing disasters. Therefore, this study aimed to clarify the mechanism in safety management and disaster occurrence. In order to accomplish the purpose, it identified and classified the factors related to accidents, reviewed the causal relationships among them, and suggested the influence diagram. The results of this research are expected to contribute to reinforcing the preventive management, and facilitating the development of integrated site control system based on safety risks.

The small and medium construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the framework of integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

Analysis of benthic micro-invertebrate community structure from the Pyeonghwaui Dam was investigated from May 2006 to October 2008. Total taxa of benthic micro-invertebrates were 5 phylum, 8 class, 15 order, 44 family, and 97 species in 2006, and 5 phylum, 7 class, 15 order, 48 family, 103 species in 2008. Mean dominance index at St. 1 to St. 5 were 0.36, 038, 0.38, 0.21 and 0.29. Mean species diversity at St. 1 to St. 5 were 3.84, 3.34, 3.13, 4.84 and 4.28. Although the dominance index of Lentic area was higher than Lotic, but the diversity was lower than Lotic area.

The Purpose of this study was to comprehend the influence that worker's job stress caused by the distinct characteristics of construction work affect on construction management. Proven through previous studies of job stress measurement method, physical environment, job demands, job autonomy, interpersonal conflict are derived as typical factors. We analyzed causal relationships between the factors using structural equation modeling under the hypothesis that job stress have effect on the construction management. As a result, successful job stress management for construction management plan is proposed.
