본 연구는 표준화된 밀 메주를 제조하기 위해 원료밀의 도정에 따른 수침 및 증숙조건과 품질특성을 조사하였다. 수침시간에 따른 2분도 밀, 5분도 밀, 통밀, 밀가루의 물리적 특성변화를 조사하기 위해 무게, 부피, 수분 함량, 수분 흡수량을 살펴 본 결과, 대부분의 밀에서 수침 4시간 이후에는 평형상태에 도달하였다. 원료밀 종류에 따른 증숙시간을 조사한 결과, 통밀을 제외한 밀원료의 증숙시간은 $100^{\circ}C$에서 10분이 적합하였다. 최적 수침 및 증숙조건으로, 가공한 2분도 밀과 5분도 밀을 각각 A. oryzae와 B. subtilis M1으로 발효하여 우리밀 메주를 제조한 후 일반 성분 및 효소역가를 비교한 결과, 황국균을 사용한 경우 발효 효율이 더 우수하게 나타났다. 또한 2분도 밀보다 5분도 밀에서 총당, 환원 당 및 ${\alpha}$-amylase 역가가 높게 나타나, 우수한 밀 메주의 제조를 위해 5분도 밀을 A. oryzae로 발효하는 것이 효율적이라 사료된다.

본 연구는 청소년 대상 기업가정신 교육의 효과성을 구체적으로 살펴보고 이의 수준을 제고 하기 위한 교육 방법론을 탐색하는데 주된 목적이 있다. 이를 위해 '식품(푸드)'을 주제로 '디자인 씽킹' 기반의 기업가정신 교육을 경기도 소재 중학교 및 고등학교 각 1개교에서 재학생들을 대상으로 실시하였다. 선행연구를 통해 기업가정신교육 효과성 측정에서 강조되는 9가지 영역(기회발견, 기회 활용, 창의성 역량, 진로준비 행동, 기업가정신, 창업 의지, 셀프리더십, 사회적 문제해결력, 교육프로그램 목표)을 기초로 '청소년기업가정신교육' 효과성 측정을 위한 탐색적 연구결과는 다음과 같다. 첫째, 디자인씽킹을 활용한 청소년기업가정신교육 후 9개 차원의 모든 측정값이 통계적으로 유의미하게 높아졌는데, 특히 '기회 활용' 차원과 '창업 의지' 차원이 가장 높게 상승했다. '기회 활용' 차원이 유의미하게 두드러진 배경에는, 금번 교육에 참여한 학생들이 '디자인 씽킹' 방법론을 '식품(푸드)' 이라는 구체적인 비즈니스 주제와 결합하여 적용한 실제적 경험을 처음 해보았기 때문에 보인 반응으로 추론된다. '창업 의지'의 경우는 선행연구에서와 같이 교육 참여 여부 또는 경험에 따라 변화의 정도가 가장 큰 만큼, 향후 '청소년기업가정신교육'의 효과성에서 중요한 변수로 다루어져야 함을 확인하였다. 둘째, 9개 차원에 대한 교육 효과분석을 위해 성별, 수강 동기별, 창업동아리 경험 여부 등 응답자특성별로 분석했다, 그 결과 종합지수의 경우 성별, 학교, 기업가정신교육참여 경험 여부에 상관없이 사전-사후 측정값이 통계적으로 유의미하게 상승했다. 특히 수강동기별로 살펴보면 본인 관심과 주위 추천이 통계적으로 유의미하게 높게 나타났다. 이 결과에 대한 해석을 위해 교육이 수행되었던 학교의 교사를 대상으로 심층 인터뷰를 실시한 결과 학생들이 자율적으로 참여하는 동아리 활동에 교사의 영향력(추천)이 크기 때문으로 판단했다. 향후 연구에서는 기업가정신교육이 9개 차원에 어떠한 경로로 영향을 미쳤는지 경로 메커니즘에 관한 연구가 수행되어야 할 것이다.

10kW wind turbine has been successfully commissioned at the King Sejong station in April, 2006. The wind turbine installed is a part of the R&D program for developing a solid wind/diesel hybrid power control system for a remote area such as Antarctica. At the same time, the current research aims to develop an anti-icing and de-icing technologies for a small wind turbine rated under 50kW. Since its commissioning, the turbine has generated about 500kWh for 47days without any system faults. Although sufficient data have not been obtained yet, any trouble has not occurred in the wind/diesel hybrid system based on the current analysis. Concerning on the environmental impact by the wind turbine operation, the turbine is installed within the station boundary in order to meet the Madrid protocol. Therefore, wind turbine operation meets the international requirements for preservation of antarctic ecosystem.

1.The domestic waste generated in Iksan city was 177 tons a day last year. 27 tons of that were recycled daily. Due to increased awareness the recycling rate also increased. 2. It is preferred to get continuous publicity and to enforce the program steadily to activate exchange centers and places like a flea market for reusable things, which will lead to increase the life-span of the current designated landfill site. 3. Because burying food waste in underground will be prohibited from year 2005, the reutilization of food waste by feeding domestic animals like ducks and making artificial fertilizer are preferred. 4. The case of Iksan city is expected to be a model to other cities by establishing a display room to accommodate its detail work demonstration, displaying modeled utilization items and exchange center, incinerator, duck ranch, lawn ground, etc. for making a city as an environmental preservation city model.

Many countries have been interested in sustainable development of buildings for environmental preservation. Thus it is significant to assess building envelopes in terms of $CO_2$ emissions owing to Kyoto Protocol. In this paper, a Double Skin Facade(DSF) installed in a general office building was assessed by $CO_2$ emissions(one of the performance-based assessment). To predict $CO_2$ emissions caused by the building energy consumption, the dynamic simulation program(Energy Plus) and $CO_2$ emission factor was used. Because DSF has various airflow regimes, pre-simulation runs were conducted to decide proximate optimal airflow regimes depending on seasonal variation. It is shown that the DSF can achieve 17.1-36.5% of annual energy savings.

This paper presents the implementation of the Blatz-Ko hyperelastic compressible model in a finite element program to deal with large deformation problems. We show analytically and numerically that the minimum number of increment steps in the Newton-Raphson algorithm depends on material properties and applied loads. We also show that this dependence is related to the orientation preservation principle. So we propose a convergence criteria based on the sign of eigenvalues of the deformation gradient matrix.

관광개발에 따른 심한 환경변화가 예상되는 지리산 국립 공원의 어족자원을 보호하기 위한 기초자료를 얻고자 이 지역의 어류분포상을 조사하였다. 국립공원내 하천에서 확인된 어종은 잉어과, 퉁가리과 및 농어과가 포함된 3과에 속하는 4종이었다. 우점종은 갈겨니였으나 이미 보고된 자료보다는 약간 감소추세을 보이고 있다. 따라서 이 지역에 대한 각별한 보호와 분별있는 관광개발이 요망된다.

The purpose of this study is to analyse the difference in college students' acknowledging of life environment pollution and practical consciousness between their characteristics. This study can be considered to be used as a basic data to suggest the direction of college's environment education and environmental preservation. This study was conducted using questionnaires with 216 college students (71 males and 145 females) of D University in Daegu area from September 20 to 23, 2004. Each of questions about their acknowledging of life environment pollution and practical consciousness was scored on a 5-Point Likert Scale, and then was analysed using the SPSSWIN statistic program.

Purpose: Pathologic tooth migration (PTM) commonly occurs in the anterior region and is associated with periodontal disease. The treatment of PTM of anterior teeth can be complex and time consuming, and a multidisciplinary approach is often required. Materials and Methods: The patient was a 38-year-old woman with a chief complaint of saving and realigning her elongated maxillary left central incisor. This paper describes the successful combined periodontal regenerative (guided tissue regeneration) and prosthetic treatment and a 2-year follow-up of maxillary central incisor with pathologic tooth migration, deep intrabony defect, and poor prognosis. Results: The right maxillary central incisor was restored by laminate veneer and the left by all-ceramic crown. The patient had no pain and discomfort and was satisfied with the outcomes of her treatment for 2 years. She has maintained her recall program at the Department of Periodontology at 3 months interval. Conclusion: The key step in the successful treatment of PTM in anterior region is to obtain a high level of cooperation from the patient. Maintenance of the treatment result of PTM is dependent on the continuous preservation of periodontal health.
