평가는 교수와 함께 교육 목표를 이루는데 있어 핵심적인 역할을 한다. 그렇지만 평가는 교수법의 발전 속도에 비교하면 상당히 느릴 뿐만 아니라, 교사는 물론 학생들에게 부정적으로 비추어지고 있다. 본 논문에서는 시험이 학생들을 동기화시킬 뿐만 아니라 그 자체로 중요한 학습 경험임을 강조하면서, 학습을 위한 평가를 활성화시키기 위해 테크놀러지를 이용한 평가 방식들을 소개하였다. 개발을 물론 어느 정도 연구가 이루어진 테크놀러지를 활용한 평가 기법을, 수행평가와 선다형의 개선안으로 대별하였다. 수행평가를 위한 기법에서는 논술채점, 지식 지도 제작법, 그리고 학습자 모형을 이용한 평가기법이, 선다형의 개선안으로 적응형 컴퓨터화 검사, 다중평가 및 변형선다형 방식이 각각 상술되었다. 결론에서는 평가를 통한 교육 효과를 극대화하기 위해서는, 교사는 물론 학생들의 평가에 대한 태도 변화 교육과 실제 교육 현장에서 쉽게 활용될 수 있는 컴퓨터를 이용한 평가기법의 개발과 보급의 중요성이 강조되었다.

대향류 확산 화염의 매연 생성 특성에 대한 실험적 연구가 수행되었으며, 그 결과 에틸렌 ($C_2H_4$)-프로판($C_3H_8$) 혼합 연료의 경우 매연 생성 상승 효과 (synergistic effect)가 관측되었다. 프로판과 에틸렌의 PAH 생성 양상이 상이하게 나타났으며, 소량의 프로판을 에틸렌 확산 화염에 첨가할 경우 순수 연료에 비하여 매연 및 PAH (다중 고리 방향족 탄화수소; polycyclic aromatic hydrocarbon) 생성이 증대되었다. 단조적으로 변화하는 아세틸렌($C_2H_2$) 농도와 단열 화염 온도를 고려할 때, 이러한 결과는 HACA (H-abstraction-$C_2H_2$-addition) 반응만으로는 확산 화염에서의 매연 발생 및 성장을 설명할 수 없음을 의미한다. 수치해석과 실험 결과의 비교로부터 초기 PAH의 생성 과정을 규명하였으며 이 과정에서 C3 화학종의 재결합 반웅이 매우 중요함을 확인할 수 있었다. 또한, 이러한 C3 화학종과 C2 화학종의 상호 보완적인 역할에 의하여 에틸렌-프로판 혼합 연료에서 매연 생성이 증대됨을 밝혔다.

This study was conducted to predict and evaluate the uncertainty of safety after closure of the second phase surface disposal facility of the Gyeongju intermediate and low level repository in Korea. In this study, four scenarios are developed considering both intact and degraded states of multi-layered covers and disposal containers; also, the fluid flow by a rainfall into the disposal facility is simulated. The rainfall conditions are implemented based on the monthly average data of the past 30 years (1985~2014); the simulation period is 300 years, the management period regulated by institutional provisions. As a result of the evaluation of the basic scenario, in which the integrity of both of the containers and the covers is maintained, it was confirmed that penetration of rainfall does not completely saturate the inside of the disposal facility. It is revealed that the multiple cover layers and concrete containers effectively play the role of barrier against the permeation of rainfall.

Objectives: The purpose of this study is to summarize results from 11 domestic studies about sick role behavior applied health belief model and to assess the effectiveness of components on behavior change by using meta-analysis. Methods: We collected the existing literatures by using major web search of 'pulmonary tuberculosis patients', 'health belief model', and 'sick role behavior' as key words and by reviewing content of journals. Quantitative meta-analysis was performed by SAS program. Results: Among 66 articles, 11 studies were selected for quantitative meta-analysis. The knowledge level about pulmonary tuberculosis had more effect for only sick role behavior as general characterisitcs(d=0.7870). All the components of health belief model produced significant effects on sick role behavior with the magnitude of effect size from 0.31 to 0.73. The largest effects were benefits on actions of sick role behavior. Conclusions: Overall, these investigation provide very substantial empirical evidence supporting health belief model dimensions as important contributors to the explanation and prediction of sick role behavior among the type of health related behavior in pulmonary tuberculosis patients. Strategic intervention including health education, etc. based on health belief model showed clear advantage in improvement of behavioral change.

M&S in the field of national defense is a battle system has been highly spotlighted for obtaining weapon systems, analyzing and experimentation of battle effects to reduce costs, time, and risks. It is classified as Campaign, Mission, Engagement, and Engineering levels by detail of description. In engagements, many situations on the battle field which are really unpredictable are required to be considered on the view of diverse tactics. Thus, engagement simulation is in demand to use for forecasting real-world battle situations by inserting various components which consists of real engaging situations into virtual local battle field. While developing the engagement simulation, adopting the concept of agent-based simulation gives it benefits which are improved autonomy, composability, and reusability of entities. It means reducing the time, cost and effort to develop the simulations. This paper concentrates on the framework of multi-agent based engagement simulation using Cougaar Architecture.

This study was conducted with the purpose of examining the direct effect of daily life restrictions on the behavior of people with physical disabilities who are easily exposed to 'disaster inequality' on emergency behavior, and comprehensively examining the mediating effect of depression and residential environment in this relationship. For this purpose, a total of 803 persons with physical disabilities aged 20 years or older were analyzed among the panels of the second year(2019) of the Panel Survey for People with Disabilities. As a result of the analysis, first, the daily life restriction of the physically disabled had a positive(+) effect on depression, a negative(-) effect on the residential environment and emergency behavior and depression had a negative(-) effect on the emergency behavior. The residential environment had a positive(+) effect on behavior in case of emergency. Second, it was found that depression and residential environment had a mediating effect between daily life restrictions and emergency behavior of the physically handicapped. In other words, it suggests that the living environment and depression can play an important role in the effect of daily life restrictions on the behavior in case of an emergency. Based on the analysis results, the implications of the study were suggested.

The purpose of this study is to examine the effects of sleep pattern on regular exercise and to examine mediating effect of subjective health status in the relationship between sleep pattern and regular exercise of older people. For the purpose of the study, older people aged over 65 years old who participated in 2020 Social Survey conducted by Statistics Korea were analyzed. Multiple regression analyses were used and significance of mediating effect was examined using Sobel test for 4,567 older people. Results of the analyses showed that sleep pattern had a significant effect on regular exercise of older people. That is, having an appropriate sleep increased the possibility of doing regular exercise, so the direct effect of sleep pattern on regular exercise was found. Sleep pattern had a significant effect on subjective health status, so older people having an appropriate sleep perceive their subjective health status more positively. As for the mediating effect, subjective health status had partial mediating effects in the relationship between sleep pattern and regular exercise of older people. Results of this study show that sleep pattern of older people should be considered in intervention for improving practicing regular exercise.

There are many studies that intrinsic learning motivation and social support play an important role in the study of children and adolescents. However, studies examining the effects of intrinsic learning motivation and social support by measuring the actual academic performance of elementary school students are rare. This study attempted to verify the effect of intrinsic learning motivation on Korean language performance and moderating effect of social support in 5th and 6th graders in elementary school. 122 elementary school students in local county-level areas participated in this study. The Korean language test was conducted about 5 months after intrinsic learning motivation and social support of families and teachers were measured. The results revealed that Korean language performance showed a significant positive correlation with intrinsic learning motivation and social support, and also showed a significant correlation between learning motivation and social support. In the regression analysis with control variables, it was found that intrinsic learning motivation had a significant effect on Korean language performance. The moderating effect of social support was analyzed by dividing it into family support and teacher support. The interaction effect of learning motivation and social support was significant only in teacher support, not in family support. In specific, when teacher support was high, Korean language performance was high regardless of the student's learning motivation level, but when teacher support was low, the student's learning motivation mattered in the performance. Based on the results of this study, implications and limitations were discussed.
