Nowadays computer technology is being applied in various areas of apparel design. In particular, since the task of pattern making is to be performed by a set of predefined drawing rules, the effect of computer application in pattern making will be significant, There have been a large number of studies on pattern making program. For instance, the previous studies have developed computer programs for pattern making of women's wear, men's wear, children's wear, Han-Bok, etc. Most of them have focused on the development of computer program for a particular kind of apparel only and, however, have disregarded the feasibility of developing a multi-purposed computer program so that is just can be modified to adopt for various styles. For example, by widening the hem-wide of the basic H-Line skirt and then connecting its waist line and widened hem-wide, we can draw the A-Line skirt. Therefore, we have developed a program which can make a pattern for the basic skirt and can mae, with a slight change of he program, other patterns for various style as well. The objective of this paper is to identify and organize modules which will be used for developing a general pattern making computer system. This general pattern making system is a computer program by which we can draw a variety of apparel styles. This system is restricted to skirt pattern making only. there presentation scheme used in organizing these modules is an AND-OR tree, the one being often used in representing a complex problem in artificial intelligence domain.

Answer to a questionnaire. 616 students answer to a questionnaire. 49 Perfect of 616 students like to have a member with 12 students like to have a member with 12 students, 38 percent student a member with 16 students. About the period of making practical About the period of making practical application, 76 percent students like to have two or three week period. 19 percent students think it a short period and 4 percent students think it a long period. There is none who thinks 25 day period day period to be short. About making practical application, 66 percent of 616 students feel uneasy, 40 percent students feel lack of sleep and tired. Students take a pleasure in having a conversation with their friends, inviting their mother, having dinner-party and birthday party. 77 percent students want to invite their father and 67 percent students want to invite their boy-friends. It is hard to have a good personal relation about the great the result of practice, students acknowledge themselves that they have learned about Cautiousness and they are sure of good Home Manager. There are 9 difficult problems during the period. IV. Summary discussion a. Many problems come from having a number of students. b. Students feel tired with their practice if over three weeks. No Matter how good a plan is, it useless if students can't adapt themselves to it. Suggestions 1) it is good to have a member with 5 or 6 students, and it is suitable to have two or three week period, and to have an area of 20 or 30 pyung. 2) it's proposed a profess or to live together in making practical application of Home Management 3) it is proposed a professor to have a sure T.O. and to be treated better.

Studies showed that elementary school students had difficulties in the idea generation for creative problem solving, and they were also not to go through with the verification process for selecting idea. Thus, it may be more effective to provide an actualized idea generation and verification methods. In this study, we developed the creativity problem solving program with the attribute listing and PMI skills in the idea generation and verification stages respectively and applied it to six groups consisting of 5th elementary school students. We analyzed the creativity and the verbal interactions among the students at the level of interaction units. The analyses of the results revealed that the problem solving program with the creative thinking skills had significant effects on the fluency and originality that were sub-elements consisting creativity. In the analyses of interaction unit, the frequencies of the 'making suggestion' at the idea generation stage were high. And at the idea verification stage, the frequencies of the 'making suggestion' and 'receiving opinion' were high. Educational implications of these findings were discussed.

Purpose: Current study aimed at exploring the effects of ambient anger versus sadness on motive type and coping strategy type when consumers make decision. It focused on whether the negative affects of the anger and the sadness differentially induce approach versus avoidance motive at the place of making decision, and also explored the coping strategy differences between the consumers under the anger and those under the sadness, that is, which strategy is more used between problem-focused strategy and affect-focused strategy when they are under each negative affect. Research design, data and methodology: The experimental groups were divided into two types of group such as the anger-felt group and the sadness-felt group. The experiment was performed with the between-subjects design based on the anger and the sadness. Questionnaire data were collected from undergraduate students assigned to each of the anger group and the sadness group operated by the scenario method, and the data were used to verify research hypotheses by t-test. Results: - First, the anger induced the approach motive more rather than the avoidance motive in making decision. Second, to cope the negative affects, consumers under the anger used problem-focused strategy more than affect-focused strategy, while those under the sadness used affect-focused strategy more than problem-focused strategy. Therefore, this article contributes to the theory related to motive and making decision taken place to consumers under ambient negative emotions. Conclusions: Focusing on the results of this study, there could be managerial implications to brand or product marketing managers. Checking which affect consumers previously felt between anger and sadness when they are under negative affects is at issue to the brand or product marketers when they appeal their brand or product to the consumers. The marketers should build and communicate the messages about their product or brand in the respect of the points of showing problem solution or the best way to handle things to appeal the consumers under the anger. And they should develop and communicate the messages about their product or brand emphasizing the aspects of letting consumers' sad feelings out somehow or controlling their emotions to the consumers under sadness.

The moment when Electrical Vehicle (EV) starts charging or discharging is one of the most important parameters in estimating the impact of EV load on the grid. In this paper, a decision-making problem of determining the start time of charging and discharging during allowed period is proposed and studied under the uncertainty of real-time price. Prospect theory is utilized in the decision-making problem of this paper for it describes a kind of decision making behaviors under uncertainty. The case study uses the parameters of Springo SGM7001EV and adopts the historical realtime locational marginal pricing (LMP) data of PJM market for scenario reduction. Prospect values are calculated for every possible start time in the allowed charging or discharging period. By comparing the calculated prospect values, the optimal decisions are obtained accordingly and the results are compared with those based on Expected Utility Theory. Results show that with different initial State-of-Charge ($SoC_0$) and different reference points, the optimal start time of charging can be the one between 12 a.m. to 3 a.m. and optimal discharging starts at 2 p.m. or 3p.m. Moreover, the decision results of Prospect Theory may differ from that of the Expected Utility Theory with the reference points changing.

이 연구에서는 해결자 청취자 활동이 예비 화학교사의 지필평가문항 제작 과정에서 고려된 교과교육학 지식(PCK) 구성 요소 사이의 상호작용에 미치는 영향을 조사하였다. 2명의 예비교사로 구성된 4개조의 해결자 청취자 활동을 통한 지필평가 문항 제작 활동을 분석한 결과, 해결자와 청취자 역할과 상관없이 PCK 구성 요소 중 과학 평가에 관한 지식 측면을 가장 많이 고려하였으며, 과학 내용에 관한 지식과 학생에 관한 지식 측면에 대한 고려도 비교적 많았다. 그러나 과학교육과정에 관한 지식과 과학 교수 전략에 관한 지식을 고려한 경우는 적었다. PCK 구성 요소 사이의 통합 수준에서는 PCK 구성 요소 중 2가지 측면 또는 3가지 측면의 통합이 다양한 유형으로 많이 나타났으며, 4가지 및 5가지 측면의 통합도 일부 나타났다. 그러나 과학교육과정에 관한 지식 측면 등을 포함한 통합은 비교적 적었으며, 과학 교수 전략에 관한 지식 측면을 포함한 통합은 매우 드물었다. 이를 통하여 예비교사의 지필평가 문항 제작 능력 신장 및 PCK 계발전략으로서 해결자 청취자 활동의 유용성, 제한점, 효과적인 활용방안에 대하여 논하였다.
