This study was conducted on teachers who currently are teaching 'Technology and Home Economics' in high school, and teaching it alone, as opposed to team teaching. The study examined the teachers' fields of major study relative to their teaching behaviors and levels of confidence and satisfaction while teaching this course. The study also compared teaching behaviors, confidence and satisfaction among teachers who either have or have not participated in training sessions specifically-targeting teachers who are lack of relevant knowledge and skills in a major field. Questionnaires were mailed to high school teachers who were solo-teaching 'Technology and Home Economics' at high schools in Gyeonggi Do. Data from 83 respondents were used for the final analysis. The findings were as follows: First, it was determined that teachers tend to be more active when teaching subjects in which they have majored than subjects in which they have not. Teachers who have majored in home economics were most active when teaching home economics, followed by technology major teachers teaching technology, home economics major teachers teaching technology and technology major teachers teaching home economics, the last group exhibiting the least willingness to teach. Similarly, all teachers exhibited less confidence in areas not relevant to their majors, and confidence especially was lower while teaching practical skills versus theories. Teachers also were found to be less satisfied with teaching subjects outside of their majors. Second, analyzing technology majors currently teaching home economics and comparing those who have and have not participated in training sessions for home economics teaching, we found that 1) technology majors with such training feel that the training experience helped them in preparing various teaching media and in their evaluation of students' understanding of basic concepts and practices; 2) these training programs increased teachers' confidence teaching theories, but not practical skills; and 3) after they had participated in training programs, teachers' satisfaction increased in terms of producing teaching agendas and selecting textbooks and teaching media for their classes. However, training programs were found to have no effect on home economics majors who had participated in technology training programs, in terms of teaching behaviors, confidence or satisfaction teaching technology.

Taking a view of joining by welding the IN713C to SCM440 and SCM415 steel in production of turbochargers, the frictin welding process may be utilized as a new approach for joining them of other conventional welding processes. It is because the friction welding has more technical and technical and economic advantages than the other welding processes. As this welding process has the characteristics such as curtaliment of production time and materials and cost reduction, etc.. So, this paper deals with determining the preper friction welding condition and analyzing various mechanical properties of friction welded joints of the super heat resisting steel to alloy stee(IN713C to SCM440 and SCM415). And the in-process real-time weld quality evaluation technique by acoustic emission during friction welding of IN713C to SCM440 and SCM415 steels with higher confidence and relibility has been much required even though it might be the first trial approach for developing it. Then, this first study aimed to develop the optimization of dissimilar friction welding of heat resisting steels (INC713 to SCM440, SCM415) for turbine, considering on strength and toughness.

The membrane type LNG(Liquefied Natural Gas) cargo containment system is a special design structure for the large deformation behavior at LNG temperature$(-162^{\circ}C)$. The design of membrane is required great confidence so that membrane can plat role in the tightness of flammable fluid storing. LNG cargo containment is loaded and unloaded LNG between twice and five times in a week. During this process, the membrane has large deformation behavior due to the variation of temperature and pressure to the self weight. In this study, the evaluation of the fatigue strength of membrane is very important to determine the design life of LNG storage tank and to evaluate the mechanical properties at the LNG temperature. Also, in the view point of large deformation, the evaluation method is applied conservatively $\epsilon-N_f$ curve of SUS 304L.

The analog or partly digital typed interface of main control room in nuclear power plant (NPP) is gradually being replaced to the totally digitalized interface suitable for the digital environment. SKN 3,4 Nuclear Power Plant is currently developed in such a way to employ advanced displays and controls such as computerized procedure system(CPS), large display panel(LDP), and Soft control. According to the developed design process, the main control room (MCR) of the SKN3,4 was aesthetically designed based on a design concept of the health and sustainability and technically evaluated with human factors guidelines, which somehow lack of the confidence on the evaluation for the rapidly changing digital environment. The suitable review guideline for the digitalized interface and the environment was developed such as the guideline for CPS with information displays on VDU. For the guideline development, tremendous guidelines and technical papers related to evaluation issues of digital environment has been collected, analyzed and transformed to electric database forms and then built on database management system, called Design Review Supporting System to retrieve the appropriate issues for the practical usage of evaluators-in-field.

Release rate is one of the important items for the environmental impact assessment caused by radioactive materials in case of an accidental release from the nuclear facilities. In this study, the uncertainty of the estimated release rate is evaluated using Monte Carlo method. Gaussian plume model and linear programming are used for estimating the release rate of a source material. Tracer experiment is performed at the Yeoung-Kwang nuclear site to understand the dispersion characteristics. The optimized release rate was 1.56 times rather than the released source as a result of the linear programming to minimize the sum of square errors between the observed concentrations of the experiment and the calculated ones using Gaussian plume model. In the mean time, 95% confidence interval of the estimated release rate was from 1.41 to 2.53 times compared with the released rate as a result of the Monte Carlo simulation considering input variations of the Gaussian plume model. We confirm that this kind of the uncertainty evaluation for the source rate can support decision making appropriately in case of the radiological emergencies.

The country-of-origin may be used as surro-gate indicator when the consumers do not have confidence on quality evaluation. Since the global sourcing is getting popular in inter-national textile and apparel production the ef-fect of country-of-origin should be examined. The purpose of this study was to determine the effect of country-of-origin on product evaluation and its relation to the consumer characteristics. A questionnaire was distribu-ted to 524 respondents aged 18 through 35. The results indicated that the country-of-ori-gin had significant influence on quality evalu-ation. Furthermore product components such as design price fabric and workmanship were also influenced by the country-of-origin. Price was perceived as more affected variable by country-of-origin than design fabric and work-manship. The interest in country-of-origin was different according to the consumer charac-teristics. Among demographics age and in-come turned out to be significant variables to determine the interest in country-of-origin. Shopping habits of respondents such as pur-chasing price of polo-style knit shirt the place to purchase that shirt the number of shirts they have were significantly different accord-ing to the interest in country=-of-origin. The re-spondent had higher interest in country-of-ori-gin were more fashion-conscious more confi-dent on clothing purchase more brand loyal and more sensitive to price of clothin.

Purpose : This study aimed to examine the relationship between intragroup peer evaluation and self-directed learning readiness(SDLR) in an Introduction to Education class that used a team based learning(TBL). Moreover, it identified the specific components of the SDLR that predicted the peer evaluation results. Method : The research subject pool comprised of 87 $1^{st}$ students in D Health College. Each team was composed of 6~8 members, each of whom evaluated all other members on his or her team SDLR was measured by using SDLR-K-96. Results : SDLR and peer assessment scores had a positive relationship, confirming that SDLR was an important variable that could predict the peer evaluation scores. Among the SDLR factors, 'openness to challenge' and 'self-confidence as a learner' was shown to have the predictive power for the peer assessment. Conclusion : The colleges should provide dental hygiene students with learning opportunities on ability to do self-directed learning through diverse learning methods such as team based learning.
