  • The HVAC takes the most important role in the Electric Multiple Unit for maintaining the healthy and comfortable indoor environment, however we also should consider the outdoor environment in terms of "environment's friendly" because the refrigerant used for the HVAC system is strongly related with the issues of "the Protection of environment" such as "the Global Warming" and "The Ozone layer Depletion". Therefore we survey (1)the potentially harmful impact on human health and the environment through modification of the ozone layer and the Green house effect, and (2)the international and the domestic environment's policies and (3)the potential alternative refrigerants usable for the EMU HVAC in terms of "the environment friendly properties", "the performance" and (4) "the applicabilities of the refrigerant for the EMU HVAC".

  • This study was conducted with 50 5-year-old children in public schools with very similiar outdoor eco-friendly play facilities. Specific play activities were introduced in the experimental group of 25 children while the control group did nor have such activities. Results of the analysis by t-test and ANCOVA showed that the play activities were effective for implementing emotional, social and physical self-concepts. There was no effect of play activities on cognitive self-concept. Effects on prosocial behavior showed that the play activities were effective for developing abilities to control individual emotions, build human relationships and adapt to school.

  • In recent years, environmental concerns have been raised on the use of poorly biodegradable fluids in electrical apparatus in regions where spills from leaks and equipment failure could contaminate the surroundings. The newly invented vegetable insulating oil is highly biodegradable and have negligible impact on the environment, human health and the ecosystem. For development of the environmental-friendly pole transformer using vegetable insulating oil, the dielectric constructions of the pole transformer were discussed in this paper. Depending on the dielectric constructions, the AC breakdown characteristics of the Nomex insulating papers and the vegetable insulating oil were studied by simulated electrode systems. Based on the experimental results, the maximum design stress($E_{max}$) for insulation design of the environmental-friendly pole transformer were suggested.

  • Knowledge-based services are largely dependent upon human-driven works. Therefore, considering human characteristics is required when modeling processes for knowledge-based services. As an emerging technology for Business Process Management, Human Interaction Management and its supportive process management can be an alternative to deal with human-driven processes. However, current HIM does not suggest concrete method for modeling conditions that are essential to realize supportive process management. And the condition modeling of HumanEdj, the only HIM software implemented, reveals the problem of complexity. As a solution, this paper suggests a fact-oriented ontological approach to process modeling. The approach uses human-friendly form of facts for condition modeling.

  • The objective of this study is to define the plans of eco-friendly housing and the meaning of architectural imagination, and to classify diverse sources of the origins of architect's imagination to propose a desirable green housing plan. Generally, imagination which means the process of forming in the mind based on one's previous experience had been perceived negatively for a long time, however, today this perception has changed as new valuation that imagination is the only the motive of human being's behavior patterns comes out. Meanwhile, green design means planning the healthy life in the future by finding the way that people and environment can live together. In order to realize green design in our lives, some plans which concern environment, style, and alternative technology of housing. Especially, in interior design, not only by technology skills but also by green visual environment, eco-friendly houses exist. Therefore, this study examines several elements which gives green atmosphere into the house, and understands how architectural imagination comes out in eco-friendly housing design through verify some examples.

  • This qualitative case study focuses on five small and medium-sized enterprises which have put family-friendly management into successful practice. Through in-depth unstructured interviews with five human resources managers and ten employees, we describe each firm's approach to work-life balance including working hour reductions, breaks, work flexibility, and parental leave to build an overall picture. We also discuss the four key factors of the CEO's role; democratic communication between all staff, the usefulness of family-friendly certification as a starting point; and governmental support for promoting work-life balance at small and medium-sized enterprises. Finally, we suggest three political implications of governmental support, namely CEO education, changing the criteria of family-friendly certification to redefine working hours and work flexibility, and incentives specifically for small to medium-sized enterprises.

  • 본 연구는 자연 친화적 공공공간의 확보가 아동의 건강한 성장에 미치는 영향을 분석하고 독일의 사례를 고찰하여 한국에의 시사점을 도출하고자 하였다. 자연은 아동의 놀이와 신체활동을 증가시켜 인지능력과 행복도를 향상하는데 도움이 된다. 전반적으로 학업 스트레스 지수가 높고 행복도가 낮은 국내 아동을 위하여 반드시 제공해야 할 공간으로 판단된다. 그러나 독일의 '자연체험공간 사업' 사례가 보여주듯 아동을 위한 자연 친화 공간을 조성하기 위해서는 국가적 차원의 법적 지원이 필요하다. 또한 해당 사업이 주요 국가정책과 연계되어야 한다. 더 나아가 학제간 협업뿐 아니라 보호자가 자연환경에 대하여 긍정적으로 인식할 필요가 있다.

  • 본 연구는 경인지역 대학생을 대상으로 친환경농산물에 대한 지식정도를 알아보고, 환경과 친환경농산물에 대한 인식을 5점 척도로 평가하여 일반사항, 환경농산물에 대한 지식이 환경과 친환경농산물에 대한 인식에 어떠한 영향을 미치는지 알아보기 위해 실시되었으며, 그 결과는 다음과 같다. 첫째, 친환경농산물에 대한 자가 지식을 묻는 문항에 친환경농산물에 대해 '매우 잘 알고 있다'와 '잘 알고 있다'로 응답한 비율이 52.9%이었으며, 친환경농산물인증마크를 올바르게 선택한 학생은 50.9%이었다. 나머지 40.1%의 학생들이 오답으로 선택한 것 중 농산물품질인증마크가 65.8%로 가장 많았으며, 친환경농산물의 인증을 정부와 민간기관에서 병행하고 있는 것에 대해 87.0%가 모른다고 응답하였다. 둘째, 환경과 친환경농산물에 대한 인식을 5점 척도로 조사한 요인별 결과, 친환경농산물의 이미지에 대한 5문항의 평균 점수는 $3.84{\pm}0.68$로 높게 나타났으며, 5문항 중 '친환경 농산물은 건강에 좋은 것이다'라는 문항이 $3.95{\pm}0.84$로 가장 높은 점수를 나타내었고 '품질인증마크가 붙은 친환경농산물은 믿을 수 있다'의 평균 점수는 $3.70{\pm}0.92$로 가장 낮았다. 셋째, 환경에 대한 태도 3문항의 평균 점수는 $3.51{\pm}0.73$이었고, 3문항 중 '환경은 후세들을 위하여 최대한 보전하는 것이 원칙이다'라는 문항이 $4.16{\pm}0.90$으로 가장 높은 점수를 나타내어 이러한 환경보전 의식과 후세들을 생각하는 마음이 친환경농산물의 소비에 긍정적인 영향을 미칠 것으로 사료된다. 넷째, 농약에 대한 태도 2문항의 평균 점수는 $3.58{\pm}0.87$로 농약의 과다 사용과 잔류에 대한 불안감이 높았으며, 친환경농산물에 대한 인식에 영향을 미치는 요인 중 친환경농산물에 대한 자가 지식 정도는 친환경농산물의 이미지, 환경에 대한 태도, 농약에 대한 태도 모두에 유의한 영향을 나타내었다. 다섯째, 친환경농산물의 소비 증진을 위해 개선되어야 할 점으로는 '가격인하'에 대한 의견이 48.3%로 가장 많았고, '믿을 수 있는 생산자와 제조회사의 확립' 21.2%, '친환경농산물에 대한 홍보강화' 15.0%, '구매 장소의 다양화' 11.9%, '친환경농산물의 품질 향상' 8.3%, ‘품질인증 표시제도의 강화' 4.4% 순이었다. 이상에서 조사된 바에 의하면 대학생들은 친환경농산물을 환경과 건강에 좋은 농산물로 인식하고 있었으나 친환경농산물과 관련된 지식이 부족한 것으로 나타났다. 환경과 친환경농산물에 대한 좋은 인식은 구매 행동으로 이어질 수 있으며, 친환경농산물에 대한 올바른 지식은 구매 시 단순히 '가격'을 기준으로 판단하지 않게 해 줄 것이고, 끊임없는 유통 구조의 개선과 친환경농산물을 찾는 소비자의 증가는 친환경농산물의 '가격 인하'로까지 이어질 것이다. 소비자로서 바람직한 가치관을 가지고 올바르게 식품을 선택할 수 있도록 대중매체는 친환경농산물에 대한 적극적인 홍보를 수행하여야 하며 대학생들을 대상으로 식품 선택 및 소비자 교육을 실시하여 올바른 정보를 제공해 주어야 할 것이다.

  • The purpose of this research was, first, to classify work-life satisfaction among married wage workers aged 20-59 years into several distinct types based on two dimensions of work and life, using data from the 20th(2017) wave of the Korean Labor & Income Panel Study. Second, the study aimed to assess the differences in socio-demographic characteristics (sex, age, educational level, average monthly income), and workplace-related variables (weekly working hours, full-time employment, job stability, business type, family-friendly leave policies) by work-life satisfaction type. Accordingly, four types of work-life satisfaction were identified: work-life satisfaction, work-life dissatisfaction, work satisfaction, and life satisfaction. There was a significant difference in the type of work-life satisfaction among married waged workers based on sex, age, educational level, and average monthly income. Additionally, there was a significant difference in the type of work-life satisfaction for all workplace-related variables, namely, weekly working hours, full-time employment, job stability, business type, and family-friendly leave policies. In particular, proportionally higher values of work-life satisfaction were evident among the workers in companies with family-friendly leave policies such as paid leave, menstrual leave, maternity leave, childcare leave, and family events leave, whereas there was a high rate of work-life dissatisfaction among the workers in companies without family-friendly leave policies.
