At the department of prosthodontics, the elderly patients with severely atrophied alveolar ridge who have been wearing complete dentures for a long period frequently visit the clinic. In general, the open-mouth impression technique for manufacturing a mandibular complete denture to secure primary support on buccal shelf area has been prevalent. In addition, for securing retention and stability of mandibular denture, we should consider diagnosis, oral function, denture border, occlusal plane, teeth arrangement, and patient training, etc.. But in edentulous patients with severe alveolar bone atrophy, it may hardly secure retention and stability of mandibular complete denture. To promote these, some of clinicians are making an attempt manufacturing the mandibular complete dentures using closed-mouth impression technique based on several reports that compare various impression techniques including open-mouth and closed-mouth impression technique. This case report suggests closed-mouth impression technique may promote retention and stability of mandibular complete denture and compares between the two impression techniques clinically.

Ecocentric worldview is considered as worldview that overcomes present environment problems and increases animal right. This study explores the formation of an ecocentric worldview for 4th-6th graders based on Peter Singer's research that divides the development of morality into family-centered, species-centered, and ecocentric worldview. The subjects of this study were 77 4th graders, 84 5th graders, and 91 6th graders in Daegu Metro- politan City. The results of surveying students' worldview based on the questionnaire developed by dividing into 6 questions are as follows. In most of the items in grades 4-6, the rate of formation of a species-centered worldview or a family-centered worldview was higher than that of an ecocentric worldview. However, in the case of 6th grade students was significantly higher than in other grades because they learned lesson on wolf restoration in the 5th grade science class. This may be seen as an effect of education, but since the ecocentric worldview did not appear high in other questions, it is reasonable to assume that 6th graders simply recited what they learned rather than forming a true ecocentric worldview. Therefore, there is a need for education that can help students to think, judge, and act on the basis of the ecocentric worldview consistently in any situation, rather than just memorizing the knowledge of the ecocentric worldview learned.

Objective: This study was conducted to evaluate an education program for cardiocerebrovascular high-risk patients. Methods: This program was developed according to Tyler's model for curriculum development. To evaluate the effects of this program, we measured clinical outcome change (weight, waist circumference, systolic blood pressure, diastolic blood pressure) and behavior change stages (checking blood pressure, blood sugar levels, doing physical activity, consistent maintenance of food intake, eating low amounts of salt, abstention from tobacco and alcohol) before and 4 weeks after participation in the education program. The group of subjects consisted of High-risk group patients who attended basic program(32 patients), and staged program(37 patients) during KHyDDI meetings from Oct. 2009 to May 2010. Results: The staged educational program was developed three aspects(disease, nutrition and exercise)and three stages(basic, in-depth and individual education). In the staged education program, the evaluations were made by measuring clinical outcome and stage of behavior before and after education. Significant differences were found in waist circumference, systolic blood pressure, diastolic blood pressure, consistent maintenance of food intake(p<0.05), and eating low salt(p<0.001)and their self efficacy. Conclusion: In the practice-oriented staged education program, significant differences were found in the clinical outcomes and stage of behavior before and after education. Possible limitations of the study include the small number of participating subjects and the short follow-up management period, but the results indicate that continued application of this program could contribute to the prevention of cardiocerebrovascular diseases for the elderly patients with long periods of chronic diseases.

With 31 existing reservoirs selected in the Yong San River Basin, the sedimentation of the reservoirs has been calulated by comparing the precent capacity with original value, which revealed its reduced reservoir capacity. The reservoirs have a total catchment area of 13,871 ha. with a total capacity of 17.6 million cubic meter, and are short of water supply due to reduction of reservoir capacity. Annual sedimentation in the reservoir ranged from 120 to 3,770 cubic meter per square kilometer with great difference in its distribution, and the average value was 877 cubic meter. This wide disparity is analysed to come principally from the topography, geology, vegetation and hydraulics. The reservoir basin had a large portion of devastated land but has become green more and more in the last 10 years. It can be summarized that in the reservoirs with an average period of sedimentation of 26 years, the reduction rate of reservoir capacity amounts 12.5%, and 0.48% is shown for annual capacity reduction rate.

Korean youth spend tremendous time in school for preparing for college admissions. Their academic achievement and overall satisfaction with their lives are affected by how well they adapt to life in school. Successful adaptation to school is important enough to affect a student's future social life. One of the factors that affect adaptation to school is the psychological condition of adolescent anxiety. Anxiety is one of the common mental disorders that appear in people who are not familiar with new environments. Anxiety is known to be related to behavioral problems, and problems with psychological and emotional adaptation. This condition is dramatically increased in adolescents.Parental conflict in particular is known to be a major factor in affecting youth anxiety. As parental conflict became more severe, children felt more negative emotions such as anger, sadness and worry. Moreover, when a child's issue caused the parental conflict, there were more side effects in the emotional condition of the child. This study shows how parental conflict affects a child's anxiety and a child's school life.This problem is analyzed through structural equation modeling.

To meet changing education needs due to globalization, interdisciplinary convergence, and ICT development, it is necessary for engineering disciplines to provide student-centered education. Not only do teaching methods using ICT reproduce teaching contents in a digital format, but they are also expected to be effective media for constructive student-centered learning whereby learners build knowledge themselves. The aim of this study was to develop a tool for safety education using virtual reality technology. To achieve the objectives, the author defined the requirements and constraints of the tool, and implemented a 3D educational tool in a virtual reality environment. A pilot test with 10 students showed positive results.

Recently, university education is changing from content- centered to learner - centered education not to deliver knowledge unilaterally but to help student to cultivate their skills to discover and apply knowledge for themselves. It means that students' cognitive or emotional development is being emphasized. Also, because of universities' quantitative expansion, more strict evaluation on professors' research result, or conversion to a departmental system in a university organization, it has become a crucial issue for undergraduates to adapt to college life successfully. Along with this trend of university education, an academic advising system is becoming one of the most important areas in it as in not only provides students with necessary academic information but also helps them adapt to college life by developing their potentials and integrating their career and life plans. Therefore this study is going to examine the status of academic advising systems in US universities, investigate how Dongguk University's Paramita college operates its academic advising system, and find out way to establish academic advising system in Korean universities.

이 글은 1990년 10월 29일부터 11월 1일까지 서울 아카데미 하우스에서 열린 제11차 국제문헌정보연맹 아시아$\cdot$태평양위원회 학술회의에서 행한 기조연설의 내용이다. 이 학술회의의 주제인 국가정보정책의 현황과 주요 문제를 정리하여 제시하는 것이 기조연설자가 맡은 과제라 보고 첫째, 최근 수년간 한국정부가 입안 실행한 산업정보정책을 살펴보고 둘째, 일반적으로 개발도상국에서 국가산업정보정책은 누가 입안하고, 입안된 정책은 누가 실행하며, 한국의 경우는 어떤지를 살펴보았다. 산업정보정책은 한 나라의 산업정보봉사활동이 이루고자하는 여러 목표들을 열거한 것이며, 다른 분야의 경우와 마찬가지로 정부에 의하여 결정된다. 산업정보정책을 심의 결정하여 공포하는 것도, 지정된 기관에 재정지원을 제공하거나 법적 의무를 지워 공포된 정책을 실행하는 것도 정부의 책임이다. 제6차 경제사회발전 5개년 계획(1987-91) 속에 표시된 한국정부의 전반적 산업정보정책은 $\ulcorner$산업기술정보 유통지원을 강화하여 현행 산업연구원내 기술정보유통센터의 운영을 대폭 강화하고 전국적 온라인 전산망을 구축하여 산업연구원을 명실 상부한 국가의 중추적 기술정보유통기관으로 육성해나가는 한편 이를 토대로 기술정보 거래시장(테크노 마켓트)을 설치 운영$\lrcorner$하는 것이다. 산업정보정책은 산업발달을 위한 정책 속에 통합되고, 그것은 다시 경제발전 및 기타 부문의 국가발전 정책 속에 포함되는 것이 바람직하다. 한국에서 일반경제정책은 경제기획원이, 산업정책은 상공부 가, 기술정책은 과학기술처가, 재정정책은 재무부와 한국은행이, 통신정책은 체신부가 심의 입안한다. 산업정보정책의 일부를 이루는 산업정책 입안의 주요 책임은 상공부의 산업정책국에 있다. 모든 개발도상국에 꼭 같이 적용할 수 있는 국가산업정보정책 입안 및 실행 지침 같은 것을 마련하기는 어렵다. 그것은 이 분야에 개발된 일반모형이 없고 또 개발도상국이라고 하는 것이 동질집단이 아니기 때문이다. 개발도상국 사이에는 그 경제 발전면에서 뿐만 아니라 정보활동 면에서도 큰 수준 차가 있다. 각 개발도상국은 그 나라 고유의 전통과 형편에 맞는 산업정보정책을 마련하여야 한다. 그렇지만 발전 수준이 비슷한 다른 나라의 산업정보정책을 검토하여 자국의 가능성과 제한점을 바르게 이해하는 일은 적절한 정책 입안에 있어서 도움이 될 것이다. 본 기조연설은 아시아와 대양주의 다른 개발도상국 정책 입안자들에게 그러한 검토자료를 제공할 목적으로 행해진 것이다.

Currently, TK(Turn-key) projects have been implemented, the projects on TK basis still have shown several problems rather than its own merits as a bidding method. Increasing the number of claims being occurred during construction process of the projects is reality because of unclear notice of tender documents and conditions of the contract, design review system, and decision process of the qualified bidder. To establish desirable TK projects in domestic market, not only should resonable alternatives for carrying out design review system and selecting the bid winner be set up, but also proper standards for reforming irrational system of contract, bid, and notice of tender related to TK projects. This study is intended to reduce the number of claims and implement efficient projects of apartment construction on TK basis by identifying potential problems through analysis of claim examples of TK projects which have difficulties of revising contract agreement such as drawings and suggesting improvement methods for contract conditions and notice of tender docuements.
