This paper presents procedure and prediction method of internal and external stabilities when designing D.C.M, with main factors to be considered, such as chemical reaction of additive, physical properties of stabilized body and mixing strength. Results show that through case studies, a design unconfined compressive strength of stabilized body (hereafter referred to as 'compressive strength') directly depends on the quantity of cement, which is decided by laboratory test, and the compressive strength enormously affects internal and external stabilities. So laboratory mixing test to obtain the compressive strength for design allowable stress should be given careful considerations.

In order to improve areas lagged behind well-developed others ing the balanced national development. Development Promotion Areas(DPA)was designated in 1996. This study aims to develop a rational evaluation system for projects of DPA. This system has 3 evaluation steps. The first step is to evaluate 10-unit operations which are tourism, recreation, road, water supply and drainage, life environment, and so on. The second step is to evaluate 3 sub-programs such as tourism and recreation, local infrastructures and specialized industry. The third step is to evaluate comprehensively in entire area. A tentative system for project evaluation of DPA was proposed by brainstorming of expert-group. Weighting values of items in PDA were calculated through pair-comparison works of expert group using stepwise matrix sheets by AHP(Analytic Hierarchy Process).

1. Objective : This study aimed to know the concordance coefficient and diagnostic trend of 6 Sasang constitution diagnosis factors among experts, which are important to diagnose Sasang constitution. 2. Methods : We suggested each 100 cases containing body shape, face, temperament, physiological and pathological symptom and constitutional drug response to 2 groups experts, and researched expert opinions. We analyzed concordance coefficient with Kendall's coefficient of concordance W. 3. Results : 1) Experts agreed with 167(82.5%) diagnosis results of cases, but there were 33 cases(17.5%), with which even one expert disagreed 2) The concordance of priority order of Sasang constitutional factors was significantly associated within expert. 3) Experts put the priority concordance to drug response and Face, body shape, voice and Pathological and physiological symptoms in order. 4) In case by case, concordance coefficient was 47(55.9%) in group 1, 9(10.8%) in group 2, 56 (33.5%) in total. 4. Conclusions : Experts made much account of drug responses and faces in diagnosing Sasang constitution. but there were different opinions in concordance coefficient. So Sasang Constitution Diagnosis Guideline is necessary to integrate experts opinions.

Purpose: The purpose of this project was to develop an international web-based expert system using principals of artificial intelligence and user-centered design for management of mental health by Korean emigrants. Using this system, anyone can access the system via computer access to the web. Methods: Our design process utilized principles of user-centered design with 4 phases: needs assessment, analysis, design/development/testing, and application release. A survey was done with 3,235 Korean emigrants. Focus group interviews were also conducted. Survey and analysis results guided the design of the web-based expert system. Results: With this system, anyone can check their mental health status by themselves using a personal computer. The system analyzes facts based on answers to automated questions, and suggests solutions accordingly. A history tracking mechanism enables monitoring and future analysis. In addition, this system will include intervention programs to promote mental health status. Conclusion: This system is interactive and accessible to anyone in the world. It is expected that this management system will contribute to Korean emigrants' mental health promotion and allow researchers and professionals to share information on mental health.

The purpose of this study was to develop an instructional model using new technologies aiming to secure students' learnability and to enhance the public school values in the rural districts. The present study attempts to suggest a practical e-learning instructional and learning model named Group Dynamics- based Debate Instructional Model', which utilizes unique technology environment conditions in most. To develop the model, concepts of group dynamics and debate-based instructional models were reviewed. And in-service teachers in two public schools in a certain rural district were interviewed in order to collect and analyze their needs for a teaching and learning model with which they utilizes unique technology conditions as environment in most. Based on literature review and the need analysis, a group dynamics-based debate instructional model has been suggested in terms of conceptual model. And then expert assessment composing of five in-service teachers from the model schools was implemented twice in order to acquire the suggested model validation, followed by the model validation by a group of experts. Then a revised group dynamics-based debate instructional model has been finally suggested. The group dynamics-based debate instructional model is expected to build up members' affective connection in the process, to generate group value, or collective intelligence, and to establish positive discussion culture. Furthermore, beyond of just utilizing the existing materials, learners are encouraged to develop and collect their own materials and data such as expert's interview, or public news for their argument or refutation. In doing so, learners enhance their learnability as well as accountability, prompting self-directed learning, and establishing appropriate discussion culture resulting in positive learning outcomes.

고차적 사고를 요구하는 글쓰기는 배운 지식을 활용하고 발전시키게 한다. 학습 장면에서 글쓰기를 더 많이 활용하기 위해서는 동료평가를 도입하는 동시에 동료평가의 정확도를 높일 필요가 있다. 본 연구에서는 동료평가의 정확도를 높이는 방안으로, 평가 기준에 대해 학생들끼리 토론하게 하거나 전문가의 평가를 참고하도록 하는 두 방안을 탐색하였다. 대학생 150명을 대상으로 한 실험 결과, 동료평가 후 전문가의 평가를 참고했던 집단이 평가했던 글을 다시 평가할 때는 평가 정확도가 향상되었지만, 새로운 글을 평가할 때는 향상되지 않았다. 반면에, 동료평가 후 평가 기준에 대하여 토론을 진행했던 집단은 평가했던 글을 다시 평가할 때는 평가 정확도가 향상되지 않았지만, 새로운 글을 평가할 때는 향상됨을 발견하였다. 또한 토론 집단의 경우 평가 기준에 대한 토론에서 총 발언 수가 많아질수록 평가 정확도가 높아졌다. 이상의 결과는 평가 기준에 대한 토론에서 적극적이고 자발적인 논의가 활발할수록 이후 동료평가의 정확도가 향상됨을 시사한다.

This study investigates the potential for multi-cultural youths, given their innate bilingual and dual culture, to be trained as the competent ODA professionals. For the purpose of collecting information, we organized two different kinds of FGI in 2015. The first FGI was conducted with a group of 10 expert participants from August 17 to September 25. The second FGI was conducted four times, from October 5 to October 23, with 13 adolescents from multi-cultural families from Russia, Mongolia, Vietnam, India, Indonesia, Japan, and China. The semi-structured interview items were passed through a formal review process of the Institutional Ethics Committee. Furthermore, with the participants' pre-consent to recording, all recorded data were categorized through the transcription process. The results are as follows. While the potential for nourishing bilingual and dual cultural capabilities are high for the adolescent children of multi-cultural families, the expert group also emphasized the negative aspects of these capabilities being suppressed due to the relatively oppressed family environment. The expert group therefore suggests the following: building parent awareness of ODA human resources, developing an educational career transition roadmap, and providing institutional incentives for ODA. In addition, to some extent, the researchers were able to detect some positive self-esteem among the adolescent children of multi-cultural families as a result of the bilingual and dual cultural competencies required to be ODA personnel. In sum, the research provides insight into the need for national social support for the adolescent children of multi-cultural families, so that their strengths are not extinguished, in order that they might grow up as competent ODA personnel.
