International construction market have quantitatively increased and have reached up to 700 Bil. US$ through active effort of construction firms and government. In spite of this increase, substantiality issue has been constantly disputed due to qualitative problems such as lack of capability and technical shortage. To overcome these problems, many methods in performing quantitative growth and qualitative substantiality of overseas construction are being researched which showed that selection of subcontractors in general contractor is regarded as a very important success factor. However, it is difficult to make a reasonable decision for selecting the subcontractors due to the lack of evaluation standards and reliability. This study proposes an improved evaluation system through adjustment of the evaluation indicators using correlations analysis and multiple regression analysis with pre-qualification and performance evaluation of 121 firms in 6 countries.

The purpose of this study was to develope issue-centered teaching learning process plan for environment-friendly housing education and to apply it to the housing section of Technology Home Economics in a middle school. PRO-CON cooperative group model was used for the teaching learning process plans of 2-session lessons according to the ADDIE model. In the development stage, 7 activity materials and 20 teaching learning materials (4 reading texts, 12 pictures and photos, & 5 moving pictures) were developed for 2-session lessons. The plans applied to the 7 classes, 222 students, in the third grade of the G middle school in Gyeonggi-do during July 10th-17th, 2008. The results showed that the final pro-con was influenced by the rationals of juries' pro-con of each team and the representative's discussion besides one's environmental perspective. The intention to implement environment-friendly housing activities was significantly increased between before and after the lessons. The contents, methods, goals, and process of the 2-session lessons were evaluated over medium to somewhat higher levels. Those evaluations except methods and general satisfaction with the lessons were differed by sex, students' and their families' interests in environments but not by the type of housing. These results might support that pro-con cooperative group model of controversial issues on parking lot would be appropriate to environment-friendly housing lessons and could apply to broad issues on housing and various schools in other areas.

인터넷 접속서비스에 대해서는 사전적 규제를 하지 않는 것이 세계적인 추세였으나, 최근 유럽에서는 인터넷 접속서비스에 대해서 사전적 규제를 가할 수 있는 지침이 채택되었다. EU가 2003년 7월에 채택한 「2003년 프레임워크」는 종래의 수직 통합형 산업구조가 인터넷 기술발전에 따라 물리적인 네트워크, 전송서비스, 콘텐츠로 정보통신산업이 층별로 세분화되어 가고 있다는 사실을 반영한 새로운 규제체계로 평가할 수 있다. 이 규제체계의 방향성은 경쟁이 미진한 분야에는 사전적 규제, 경쟁이 활성화된 분야에는 사후적 규제를 가하는 것이다. 본 고의 목적은 일본의 인터넷 접속서비스에 관한 시장 및 규제 동향을 소개하는 것이다. 여기에서는 먼저 일본의 인터넷 접속서비스 사업자의 현황을 개관한 후, 인터넷 접속서비스에 대한 정부차원에서의 규제동향을 고찰한다. 일본에서는 인터넷 접속서비스에 대하여 사전적 규제를 하지 않고 있다는 점을 감안하여 일본의 대표적 ISP 사업자라 할 수 있는 JPIX와 NTT 동서를 대상으로 인터넷 접속서비스의 사업현황과 이들 기업에 접속하기 위한 접속조건 등을 살펴본다. 맺음말에서는 현재 일본에서 이루어지고 있는 인터넷 접속서비스에 대한 규제동향을 우리나라와의 비교 관점에서 고찰하고 우리나라에의 시사점을 제시하고자 한다.

The purpose of this study was to develop a dietary life education program for adolescents and evaluate its effectiveness. The program was divided into three areas: 'Natam' (taste education), 'Wetam' (traditional dietary life education), and 'Gitam' (sustainable dietary life education), consisting of a total of 10 units primarily focused on cooking activities. For participants aged 14~17 years, face-to-face pilot education was conducted by a trained instructor once a week for 10 weeks. A questionnaire survey was performed to evaluate the educational effect(n=72) and satisfaction(n=82) during education period. Significant improvements were observed in knowledge levels for the 'traditional dietary life education', and 'sustainable dietary life education' which were identified as insufficient in the preliminary survey. Attitude and behavior levels were significantly improved across all areas. Satisfaction was high with a score of 4 out of 5 points for all areas. In conclusion, this program was found to be effective, and further emphasis should be placed on traditional and sustainable dietary life education to enhance its impact.

본 연구는 청소년 스트레스 호르몬 변화를 보기위한 연구로 컬러 컨설팅 환경개선에 따른 스트레스 호르몬 변화를 연구하였다. 청소년 스트레스 연구들에 따르면, 아동이나 청소년도 성인만큼 스트레스를 경험하고 있고 청소년들의 스트레스는 정서적 부적응과 신체적 건강에도 영향을 미친다. 스트레스가 지속되면 부신피질에서 스테로이드 호르몬인 코티솔도 분비하는 근거를 통해 환경변화로 생긴 코티솔 분비를 측정하였다. 코티솔 분비를 통한 스트레스 반응 정도 측정은 침해성을 최소화하기 위한 간편한 방법인 타액검사로 실시하였으며 비 침습적인 방법으로 특별한 장비나 도움이 없이 수집할 수 있었고 부작용이 적은 효율적 검사였다. 연구 결과 전체 학생(46명)의 코티솔은 환경개선 사전($0.121{\pm}0.087{\mu}g/dL$)에 비해 사후($0.096{\pm}0.058{\mu}g/dL$)에 감소하였고(t=1.718, p=.093) 중고등학생(36명)의 코디솔은 사전($0.137{\pm}0.092{\mu}g/dL$)에 비해 사후($0.104{\pm}0.062{\mu}g/dL$)에 감소하였으며, 유의수준 10%에서 통계적으로도 유의미한 차이를 보였다(t=1.750, p=.089). 따라서 환경 개선 전에 비해 환경 개선 후 청소년들의 스트레스가 감소되었음을 알 수 있다. 하지만 초등학생(10명)의 코티솔은 사전($0.064{\pm}0.023{\mu}g/dL$)에 비해 사후($0.065{\pm}0.016{\mu}g/dL$)에 변화를 보이지 않아, 유의수준 5%에서 통계적으로 유의미한 변화는 나타나지 않았다(t=-0.121, p=0.906). 따라서 후두엽이 발달하는 중학생 시기는 환경 변화에 민감하며 색채 자극에 크게 영향을 미치는 시기인 만큼 본 연구에서 환경전후로 검사한 코티솔 분비의 측정값도 감소함을 볼 수 있었다. 하지만 본 연구는 환경 변화에 코티솔 분비량에 유의미한 변화를 나타내지 않은 초등학생들은 스트레스 호르몬 변화에는 차이가 없었지만 환경변화의 자극이 없었다고 볼 수는 없다.
