  • The purpose of this study was to analyze the structural model of causal effects of students' variables on science process skills. Student characteristics investigated in the study included attitude related to the science, logical thinking ability, scientific experiences, cognitive style. Covariance structural modeling procedures were used to test causal inferences about hypothesized relationships. The sample consisted of 319 6th grade students and 321 8th grade students in Seoul City, Korea. Five instruments were used in the study, TSPS(test of science process skills), GALT(group assessment of logical thinking), CEFT(children embedded figures test), questionnaire of attitude related to the science, questionnaire of scientific experience. For statistical analysis, the study adopted the structural equation modeling with LlSREL, a computer statistical program developed by J reskog and S rbom. Major findings of the study are as follows:1) Logical thinking ability has a most strong direct effect on science process skills. 2) The structural coefficient of scientific experience influence on attitude related to the science has the greatest direct one than the others in the covariance structural model. According to the results of this study, it is very importance that various scientific experiences, particularly hands-on activity, should be offer to students to improve science process skills. Also, understanding the relationships of student variable to science process skills will be helpful to decision making on the part of curriculum developers, science teachers and researchers.

  • The aim of this study is to investigate the actual state for the development of the thermally comfortable uniform for workers on a low temperature storage. Observation, interview and survey were executed focusing on the environment, clothing, and human factors which have effects on the comfort of workers. Of 400 distributed, 253 questionnaires were analyzed through descriptives, frequency, ANOVA, t-test, multi-response analysis, correlation analysis with SPSS 12.0. The results are following. Coming and going between a selling area and cold storages, the workers showed to experience a big temperature gap. They indicated to feel cold on face and hands which were not covered by clothing and have got sick because of low temperature. The workers wanted the uniform made of functional fabrics, especially heat insulation fabrics. Female workers rather than male workers, the older, and the longer their working period were, the more uncomfortable they revealed to feel. The workers who works on the daily products part or mainly on the freezer appeared to feel cold more than any other workers. In conclusion, it was found that the uniform which consider steady state and unsteady state heat transfer together must be developed.

  • The future competitiveness of construction industry is dependent on K-12 students. However, unfavorable images of construction industry have negative influence on K-12 students' decision-making of their career. This negative image makes them not want to find out what actually happens in construction industry. Consequently, it is important to give K-12 students the opportunity to know what construction employees actually do in their job. Studies show that K-12 students who encounter the job early-on are more likely to choose it as their career. In this context, this paper proposes construction educational game in which it can serve as a medium for capturing K-12 students' interest in Construction Management (CM). Based on the literature reviews, challenges of construction educational game for K-12 students which are edutainment, hands-on experience and social interaction, are derived. To address these issues, conceptual model and scenario are designed. Based on designed scenario, prototype of Simulation based Construction Game in Virtual World (SCGVW) is developed in Second Life (SL) and applicability test to K-12 students are implemented. This paper concludes with a discussion of the lessons learned and the future development steps of the construction educational game for K-12 students.

  • The purpose of this study was to investigate the satisfaction on the Gwangju Kimchi Festival. The results of this study were as follows: In terms of satisfaction on 'pre event publicity of the Festival', the satisfaction of '03 was high. It was founded that Publicity through TV was successful. The visitors' satisfaction on understanding regional cultures was low. It was consecutively low for three years. There should be strategic development plans to increase satisfaction about understanding regional cultures. It was found that TV was the major pre event information resource for the residents. Also word of mouth was the most important pre event information resource for domestic tourists. The satisfaction on access to festival was increased consecutively. Providing free shuttle buses to the festival place and placing festival placard influenced positively. There should be expansion of service facilities. There should be more strengthening of festival information services and guiding facilities. More professional interpretation systems and interpretation education are necessary. Visitors satisfied about festival products and quality of the products. Visitors satisfied with festival events programs and hands on experience based programs including making diverse Kimchi.

  • Due to a lack of objective and adequate study on the physical effects on hydroponic polyurethane waterproofing material water mixture ratio, construction site workers are having to rely on their hands-on experience to determine a mixture ratio, resulting in difficulty of maintaining quality management. Particularly in cases of rooftop exposed type hydroponic polyurethane materials, the varying temperature conditions make it further difficult for quality management control. in this regard, this study conducts tensile strength testing and compares the tensility change rates hydroponic polyurethane waterproofing materials with various water mixture ratios ranging from 0%~50% and exposed to alternating temperature change between -20℃ to 60℃ in the span of 1 hour after curing for 14 days.

  • 이 연구는 치과임상 이외의 분야에 진출한 치과위생사들을 대상으로 심층면담을 통해 졸업을 앞둔 치위생(학)과 학생들에게 들려주고 싶은 조언을 다음과 같이 네 가지로 정리할 수 있었다. 치과임상 이외의 분야에 진출한 치과위생사들은 학생들의 졸업 후 진로가 치과임상에 국한되는 것이 아니라 다양한 분야로 진출할 수 있다는 것을 강조하였다. 치과임상 이외의 분야로 진출하더라도 치과임상 경험은 해보는 것이 필요하다는 공통된 의견을 주었다. 왜냐하면 치과위생사로서의 치과임상적인 경험을 발판으로 삼아야 우리분야에서 전문적인 역량을 발휘할 수 있기 때문이라고 하였다. 진로를 결정할 시기는 졸업을 앞두고 급하게 생각할 것이 아니라, 치과임상실습을 경험한 후 충분한 시간을 가지고 자신의 능력과 적성에 맞는 길을 생각해 보길 권하였다. 학교 '성적'보다는 자신의 '적성'을 찾고, 올바른 '인성'을 길러서 실제 현장에서 그 역량을 제대로 발휘할 수 있는 '실력'을 갖추기를 바랐다.

  • 본 연구에서는 연령에 따른 운수업근로자의 직무특성과 건강이 사고경험에 어떠한 영향을 미치는지를 확인하고, 이를 통해 사고예방과 고령운수업근로자에 대한 다양한 관점을 제시하고자 하였다. 산업안전보건연구원에서 실시한 '제 4차 근로환경조사'의 자료를 활용하였으며, 최종적으로 1,997명의 운수업근로자 자료를 상관분석과 교차분석, 로지스틱 회귀분석을 실시하였다. 연구 결과, 운수업근로자의 연령과 사고경험에는 상관관계가 나타나지 않았다. 운수업근로자의 특성과 사고경험과의 관계에서 고령근로자의 경우, '직무수행 중 실수 시 타인이 다침', '근골격계 문제', '심혈관계 문제', '손이나 팔의 반복동작' 순으로 유의한 영향을 미치는 것으로 나타났으며, 이 변수들에 대한 모델 설명력은 56.9%였다(p<.01). 비고령근로자의 경우에는, '우울 및 불안장애', '직무와 안전과의 관계', '직무수행 중 실수 시 타인이 다침', '노동조합 여부' 순으로 유의한 영향을 미치는 것으로 나타났으며, 모델 설명력은 21.8%였다(p<.01). 따라서 추후 운수업근로자들의 사고예방을 위해서는 연령 이외에도 건강과 직무특성 등 다양한 변수를 고려한 접근이 필요할 것이다.

  • 시뮬레이터는 산업교육에 있어서 유용하게 활용되고 있다. 특히 고도의 가치산업이나 위험한 시스템에 대한 교육을 실시하기 위해서 사용하기에 적합한 방법이다. 또한, 이론교육에서 체험형 교육으로 전향되는 산업교육에 있어서는 교육의 효과를 위하여 필요하다. 따라서 현장에서 실무에 도움이 되도록 LPG 이송방법에 대한 교육극대화를 위하여 이론교육과 체험교육의 중간 매개체 역할의 장비를 개발하여 교육에 적용하였다. 교육에 적용한 결과 교육장비가 이송시스템 이해도가 4.86점/5점, 현장에서 활용도는 4.47점/5점, 장비의 만족도는 4.48점.5점으로 나왔다. LPG 이송시스템 교육장비(시뮬레이터)가 교육에 활용시 효과적인 것으로 판단된다.

  • This study aims to clarify the asset evaluation attributes of imported brands exclusively by department stores based on qualitative study. For the qualitative research, hands-on staff of the branch office who had at least 5 years experience in PB-related positions at one of the four domestic department stores(Lotte, Shinsegae, Hyundai, Galleria), and at least 20 years old adults who had purchased imported brand items exclusively by a certain department store(Shinsegae, Lotte) were included. The asset evaluation attributes of department store-exclusively imported brands were drawn up through the one-to-one in-depth interview method. As a result of qualitative study on the asset evaluation attributes of department store-exclusive importation brands, it turned out that there were 4 factors in view of business entity - stability, profitability, growth potential, and relationship, and that there were 6 factors in view of consumers - product quality, recognition, country of origin, image, preference, and reliability. In comparison with the existing preliminary study, it was notable that relationship in view of business entity, and country of origin in view of consumers were added to the asset elements.
