Circuit theory is a systematic study that analyzes and designs the most basic circuits in the field of electrical and electronic engineering. Circuit theory courses are organized as major courses for one or two semesters in the second year of university, so that electrical and electronic engineering students must learn. Experimental courses are being together organized for students to enhance understanding of circuit theory and cultivate the skills and the abilities of circuit design through experiments with actual circuits. This paper is a case study on the teaching method applied in electric circuit design and experiment courses to enhance the learning effect on the experimental education that supports circuit theory. To do this, we propose a 15-week instructional model consisting of theory study, simulation, experiments, and design projects. In the proposed model, the simulation and preliminary experiment preparation process are reinforced to complement the theoretical concept and the design project is introduced to acquire practical circuit design skills as engineers. The results of five-year operation demonstrate the effectiveness of the proposed model.

Universities should provide experiential learning in subject and non-course subjects so that students can graduate with job competency related to their major and the experiential learning includes capstone design implemented on campus and field training conducted by companies. In particular, the decrease in industry participation in short-term (4 weeks) and mid-term field training (8 weeks) due to the implementation of standard field training introduced from the second half of 2021 is making it more difficult for students to gain practical experience. To solve this problem, in this paper, we propose an industry-participatory capstone design & field practice linkage model that combines capstone design and professional practice to solve the technical difficulties of companies. Participating students find solutions to corporate difficulties in the capstone design process and produce prototypes for solutions during the field practice period, focusing on the case of the department of electronic engineering at Gyeongbuk Y University. We believe that it is one of the good models of industry-university cooperation education in which universities and industries win-win.

This study aimed to empirically test the causal model of stress-coping-adaptation for unwed mothers, which was built upon the Lazarus and Folkman's(1984) "Stress-Coping-Adaptation" model. In doing so researchers endeavored to provide practice implications as well as theoretical ones which would be helpful both to alleviate the unwed mothers' stress level, and to facilitate social adaptation of the unwed mothers. In order to fulfill research purpose data were collected from the national sample of 423 unwed mothers in Korea. The results showed that the overall goodness of the fit of the proposed causal model was excellent. Most of the path coefficients between social support, stress, coping, and adaption turned out to be statistically significant. The moderating effects of "pursuit of social support" between stress and adaption was not significant statistically, though. Implications and suggestions were provided to reduce the level of stress of the unwed mothers, and to facilitate the adaptation of the unwed mothers.

Web-based distance teacher training should focus on increasing self-directed problem solving skills of trainers by problem-based instruction(PBL). Performance assessment evaluates achievement of learning goals through the practical performance learning to solve problems in the real situation. This study proposes a web-based performance assessment model for the distance teacher training. It reflects fairness and objectiveness issues of performance assessment which elementary teachers are concerned about through the survey on distance teacher training, and relieves instructors from overload of managing and scoring performance tests. The proposed model provides problem-based learning situations, interactions between individuals and groups, and web-based cooperative evaluation and the peer evaluation.

The purpose of this investigation was to examine the mediating effects of delinquent peers between attachment to parents, low self-control and adolescent deviant behaviors. After specifying a research model based on Gottfredson and Hirschi's general theory of crime and Hirschi's control theory of delinquency, the study analysed the model using structural equation modeling. The data for this investigation came from a sample of 2,448 Korean adolescents. The results showed the both measurement model and structural model had a good fit to the data and all paths of structural model were statistically significant. The main findings were the attachment to parents and low self-control had direct and indirect effects on adolescent deviant behaviors through delinquent peers. The implications for practical intervention and further research in the field of delinquency were discussed.

The 'Program outcomes and assessment' is an important criterion evaluating of engineering education in accreditation of engineering education. ABEEK prescribes program outcomes which are the basic capabilities in the application of the fundamental knowledge and practical tools of the engineering field. Also ABEEK asks to prove that all programs are constructed a proper educational curriculum and are satisfied program outcomes and CQI. Therefore program outcomes must satisfy both two key points. First, as a quality control aspect, engineering programs must prove that graduates of accredited programs can perform twelve capabilities. Second, as a continuous quality improvement aspect, accredited programs have to upgrade a level of engineering educational quality. Consequently the purpose of study is to introduce a new model for CQI and QC systems, implementing strategies as an actualizing of program outcomes.

This study uses the LEAP model that is a long-term energy analysis model to analyze reduction potential on S city residential sector energy usage for greenhouse gas emission. Energy consumption of S-si in 2009 is consumed most in residential and commerce sector by 39.1%. Also, energy and greenhouse gas emission of residential sector is expected to increase due to increase of households. Therefore, greenhouse gas reduction measures are desperately required in residential sector. For this study recognizes energy consumption of S-si residential sector and has established reduction measure of S-si residential sector greenhouse gas through literature search on domestic and foreign climate change correspondence policies. Also, construction of greenhouse gas reduction potential by reduction measures through LEAP model. There were a total of 5 reduction measures scenarios is Reference Scenario, LED Lighting, Energy Alternative, Green Life Practice, and Total Reduction Measure. As a result, greenhouse gas emission of Light Emitting Diode Lightings by 2020 was $1,181.0thousand\;tonCO_2eq$, decrease of 6.1% compared to the Reference Scenario and Greenhouse gas emission of Energy Alternative by 2020 was $1,171.6thousand\;tonCO_2eq$, decrease of 6.8% compared to the Reference Scenario.

The purpose of this study was to examine the mechanism through which youth school-based mentoring program impacts mentees' psychological and school-related outcomes such as self-esteem, self-efficacy, and attitudes toward school. The hypothetical model was assumed that mentors could improve their mentees' developmental outcomes through positive relationships with mentors as good role models and enhancement of help-seeking orientation. To investigate the mediating effect of process-related outcomes, structural equation modeling was used. The 97 adolescents were recruited through referral and random selection from middle schools in Seoul. The result showed that the effects of program participation were mediated by proximal changes in connectedness to role models and development of help-seeking orientation that, in turn, led to facilitate more positive attitudes toward school and academic activity, and improve psychological outcomes. Practice and policy implications as well as further research topics were discussed to aid the search for highly effective mentoring programs.
