국내 섬유ㆍ의류산업의 고비용/저효율 구조를 혁신하기 위해서는 산업간 공급사슬을 효율적으로 관리할 수 있는 QR 시스템의 도입이 불가피할 것으로 보인다. QR 시스템의 성공적인 도입을 위해서는 정보기술적 측면에서 효과적이며 통합적인 정보 파이프라인의 구현, 그리고 기업문화적 측면에서 서로 다른 기업문화와 산업환경하에서의 기업 상호간 전략적 협력관계의 창출이 필수적 요건이라고 하겠다.

This study examined the difference between parents' and teachers' recognition about problem behaviors of children. The findings showed that there was a distinct difference between parents' and teachers' recognition about all problem behaviors of children. Especially, teachers had more recognition about problem behaviors of children than parents. And the reactive interaction and the actual prevention in educational institutions were preferred in the difference between parents' and teachers' recognition about a teaching strategy for children, such that teachers had significantly higher recognition about a teaching strategy for children than parents did, while there was no significant difference in the strategy for social emotion. This means that teachers should originally control and manage various problem behaviors based on the common teaching strategy, which is socio-emotionally recognized, rather than the biased teaching strategy. But the teaching strategy of reactive interaction is preferred in accordance with the type of problem behaviors between teachers and children and the children who show problem behaviors. Especially, teaching strategies of reactive interaction and actual prevention focused on the inhibition and prevention of children's problem behaviors are preferred in light of children's characteristics of many unexpected problem behaviors.

In this study, the effects of reciprocal peer tutoring strategy on science achievement, science learning motivation, and self-esteem were investigated. Three classes of eighth graders (N=94) at a coed middle school were sampled for the study. They were divided into the comparison group, the cooperative learning (CL) group, and the reciprocal peer tutoring (RPT) group. Students were taught about the separation of mixtures for 13 class hours. Mid-term science examination scores were used as a blocking variable. The two-way ANCOVA results revealed that there were no significant differences among the three groups in the science achievement test, although the scores of the RPT group were higher than those of the comparison group. In all the subtests of the science learning motivation questionnaire, the scores of the RPT group were significantly higher than those of the comparison group. The scores of the RPT group were significantly higher than those of the other groups especially in the confidence part of the science learning motivation questionnaire. In the self-esteem test, the low achievers in the RPT group scored significantly higher than those in the CL group.

In this study, it was considered that not only the physical form should be electronically copied in virtual reality modeling for real problem solving, but also the interrelationship between the object and the user to be simulated. To this end, a plan was proposed to add user-space interaction elements that occur in real space to virtual reality application. This study is set in virtual reality modeling to solve safety problems in public toilets, and there should be a reasonable principle to add interaction elements with users to virtual reality modeling, and the basic environmental design strategy for crime prevention was used. As a result, it was shown that it was reasonable to derive interaction elements according to certain principles, such as the basic strategy for environmental design for crime prevention.

This study examines the economic effects of a developed country's minimum quality standards (MQS) and mutual recognition agreements (MRAs) between countries. Based on the results of such analysis, it also considers the optimal MRA strategy for South Korea. For this purpose, the paper constructs a simple three-country model in which the representative firms in each country supply differentiated goods to the developed country market. The analysis results are as follows: First, the rise in the MQS of a developed country intensifies the competition level, reduces the profits of all firms, and raises the developed country's consumer surplus. In addition, if one of the firms exits the market due to the MQS, competition is relaxed, and the profits of the remaining firms increase. Second, countries subject to MQS can improve their social welfare through the MRAs; thus, it is essential to utilize them strategically. In the case of South Korea, the optimal situation is to have an MRA with the developed country or for all three countries not to have any MRA.

The purpose of this research is to explore the strategy of teacher and the strategy of child in teacher-child interaction according to related variables. The participants of this research are 2 classroom teachers and their 54 5-year-old kindergarten children(27 boys and 27 girls). To collect the data, child's classroom activities were observed and videotaped using event sampling 90 times(30 times per beginning, middle, and end). Repeated test, two-way ANOVA, Scheffe test used for data analysis. The results of this research were as followed; First, over time there were differences between strategies of teacher and strategies of child during teacher-child interaction. Second, in child variables there were differences in strategies of teacher and strategies of child during teacher-child interaction according to child's gender. Third, in environment variables there were differences between strategies of teacher and strategies of child according to play rules and play areas.

본 연구는 최근 수요환경의 변화를 겪고 있는 항공사-여행사 관계를 중심으로 영향력 관계, 거래 집중화, 영향전략 등에 대하여 검토하고 있다. 항공권 판매 시장의 수요환경은 최종고객 중심으로 전환되고 있다. 이러한 환경적 변화는 항공사 유통역량 평가에 부정적인 영향을 주고 항공사의 낮아진 영향력은 여행사의 거래 집중화 경향을 감소시킬 것이라는 가설을 수립하였다. 추가하여 최종고객 중심의 수요환경 변화가 경로 구성원 상호 영향전략에 미치는 영향에 대해 가설을 수립하였다. 즉 영향력 관계가 비대칭적인 상황에서도 수요환경이 최종고객 중심으로 전개된다면 항공사의 영향전략에 대해서 여행사는 동일한 영향전략을 수행한다는 가설을 수려하였다. 그리고 항공사의 영향력과 여행사의 거래 집중화 관계에 경로 내 영향전략 유형에 따른 조절 효과를 가설화 하였다. 결과는 대체로 기대했던 가설이 채택되는 방향으로 나타났다. 그러나 비강압적 전략의 사용과 관련된 두 가지 가설은 기각되었다.

반복적 죄수의 딜레마 게임은 사회적 상호작용, 경제활동, 국제관계 등 다양한 현상들을 모델링하기 위한 하나의 방법이다. Axelrod가 이 게임을 제안한 이래, 많은 학자들이 다양한 방법으로 연구를 진행해 왔으나 대부분은 게임자 개인 전략이나 이득함수의 개선에 중점을 두었다. 본 논문에서는 죄수의 딜레마 게임에서 다양한 개체 선택방법과 의사결정 방법을 이용한 전략적 연합을 적용함으로써 일반화 성능을 높이는 결과를 도출하였다. 전략적 연합은 결합 조건이 만족할 경우 자율적으로 형성될 수 있으며, 연합에서의 의사결정은 개인의 의사결정보다 우수하다는 가정 하에 실험을 진행하였다. 실험 결과는 이러한 가정을 뒷받침하여 전략적 연합을 이용한 전략이 테스트 전략에 대해 일반화 성능이 우수함을 보여주고 있다.

The purpose of this study was to develop teaching materials using pyramid model of divergent thinking, inverse pyramid model of convergent thinking and evaluate the effects of its applications. The teaching materials was implemented to 110 students (The experimental group is 57, The control group is 53) in middle school for about 8 months (from May to October). Results indicated that the experimental group presented statistically meaningful improvement in creative thinking skills, especially in fluency, flexibility and originality. There was no interaction effect about creative thinking skills between the teaching strategy and cognitive level, achievement, gender of those students. Also the teaching materials contributed to improve critical thinking skills, especially in making hypothesis, control of variables transformation and interpretation of data. There was no interaction effect about critical thinking skills between the teaching strategy and cognitive level, achievement, gender of those students.
