The purpose of this study is to introduce the evolution of corporate family-friendly policies and programs, a recent business issue throughout the world. In addition, this study suggests implications for a corporate reference guide to work-family policies and programs by providing a comparative analysis of the typical stages of development of U.S. corporate family-friendly policies and programs, and by presenting model initiatives of Korean and American family-friendly companies. Just as technological changes at the time of the Industrial Revolution altered the relationship between workers and their work, more recent technological advances have again transformed this relationship, offering the promise of a society in which work demands a smaller portion of the worker's time and permitting the worker more freedom and control over work conditions. These new work arrangements have the promise of producing a new paradigm for work and family, based on which many industrialized nations have developed family-friendly policies already. Family-friendly policies and programs can be grouped into four discernable stages in the evolution of a corporate work-family agenda. According to these stages, most companies in Korea are in the predevelopment stage or stage 1. Development of scales to assess company family-friendliness is needed to create a family-friendly workplace environment, policies, and programs. It is critical that companies have champions who have the vision to step out in kent, and the determination to ensure that the family-friendly programs are solidly grounded. Companies should develop their work-family initiatives as an integral part of a program for managing diversity focusing on needs of women and minority employees.

As the notion of environment protection changes throughout the world, construction engineers, as part of the effort to resolve environmental problems, have been actively doing research on environmental friendly porous concrete using large and non-uniform aggregate. Concrete having a great deal of continuous porosity enable water and air to pass freely through firmly hardened material, allowing necessary nutrients to reach roots of vegetation, thereby sustaining them. It is possible to prevent the exhaustion of natural resources by recycling waste concrete and industrial by-products, to reduce damage caused by the destruction of nature through effective management of natural resources, to preserve the natural environment and vegetation in urban areas by activating the soil, protecting the underground ecology system, and growing garden plants through the application of environmentally friendly concrete.

District heating and cooling systems offer highly efficient energy utilization and maintenance by centralizing heat management. More pumping power, however, is required because the water has to travel long distance from heat source to the users. In the present study, a trace of drag reduction additives is added to the District Cooling system to achieve a significant drag reduction and save pumping power. Water-soluble polymers, surfactants, and environment-friendly degradable polymers are used as effective drag reducing additives. Time dependent percent drag reductions are compared for various additive solutions at 100 wppm concentration for different water velocity. Without as an anionic surfactant, copolymer was most effective in percent drag reduction. It is found that there exists an optimal condition when copolymer is mixed with SDS. An environment-friendly degradable polymer, xanthan gum, is found to be a significant drag reduction additive. Ice slurry systems, can give less pressure drops compared with chilled water system for certain condtions. Drag reduction additives were also effective for the ice slurry system.

The purpose of this study is to research the characteristics of literature related to environmentally friendly for a village-focused green index. In order to make an assessment, keywords relating to green architecture were selected: environmental friendliness, ecology, sustainable, Noksaek (Green in Korean), green, and environmentally friendly. In addition, three keywords defining the scope of space were also selected: building, village, and city. Quantitative changes and contents of articles containing the keywords were analyzed. The result is as follows. First, 'sustainable' and 'ecology' were the terms most frequently used as parts of subjects and titles, respectively. Second, the studies relating to green architecture focused on villages mostly examine the actual conditions of the villages; criteria for environmental friendliness, analyses and evaluation of the environmentally friendly features of the village; and ways to establish a green, ecological, and sustainable village. Finally, when it came to establishing a village-focused green index, the environment, resources, and energy are shown to be very important elements. In addition, the term 'ecology' in a green index is shown to be significant for the management of the natural environment.

The purpose of this study is to analyze the effects of abolishing the low-pesticide agricultural product certification on environmentally friendly farming. A survey was conducted to quantitatively analyze farming practices and factors that change farming practice. It was found that only 17.0% of low-pesticide fruit farmers said that they will change their farming practice into organic or pesticide-free farming. With regard to the factors of farming practice change, binomial logistic regression model was applied for the analysis. In the analysis, it was found that farmers who grow the low-pesticide agricultural product are more likely to change their farming practice into organic or pesticide-free farming, as their expected price of organic or pesticide-free products is high, their area size is small, price premium of low-pesticide agricultural product is low, the frequency of their training is high. It is necessary to enhance the direct payment system to enlarge organic and nonpesticide acreage, and pest management techniques for fruits should be developed for low-pesticide fruit farmers to change their practice into organic and nonpesticide practice. Dissemination of cultivation manual, introduction of insurance to farmers, improvement of certificate system, and advertising and marketing of environment-friendly agricultural products are useful to develop environment-friendly agriculture.

본 연구에서는 GM과 non-GM작물 특히 최근 들어 그 인증량이 급격하게 증가하고 있는 친환경작물과의 공존에 관하여 검토하여 보았다. 국내의 현행 법령에 의하면, 친환경 농산물은 GM농산물의 혼입허용치를 3%로 규정하고 있다. 특히 우수농산물의 경우 단계별 조사내용을 보면 "파종단계에서 GM종자를 포함하지 않을 것"을 명시하고 있다. 반면에 우리나라에서는 아직까지는 GM 작물의 상업적인 재배를 승인하지 않고 있다. 그러나 현재 GM 벼, 배추, 감자, 들잔디 등의 환경위해성평가가 수행 중에 있는 것으로 알려져 있으며, 농촌진흥청은 "유전자변형생물체의 국가 간 이동 등에 관한 법률"이 정하는 바에 따라 GM작물의 환경위해성 평가를 전담할 수 있도록 농촌진흥청산하 소속기관 및 대학교, 출연기관 등 11개 기관을 평가기관으로 지정하여 조만간 상업적인 GM작물의 재배를 승인하기 위한 준비를 하고 있는 것으로 조사되었다. 또한 국내의 친환경농산물의 인증기관은 2008년 8월 현재 34개 민간기관으로 증가하였으며 이들 인증기관에서 부여한 친환경 인증 농산물의 재배면적 및 생산량은 해마다 기하급수적으로 늘어나고 있다. 예로서 친환경곡류의 경우 1999년도에 비하여 2007년도에는 그 인증량이 100배 (유기농)에서 2,324배 (저농약)까지 증가한 것으로 조사되었다. 이들은 2007년도의 전체 곡류생산량에 비하여 약 6.4%를 차지하였다. 특히 감자와 고구마 등 서류의 경우는 전체 생산량의 약 24%가 친환경인증농산물인 것으로 조사되었다. 이러한 현실에서 GM작물의 상업적인 재배를 승인할 경우 기존의 국내 친환경농산물시장의 유통질서에 큰 혼란을 야기시킬 수 도 있을 것으로 사료된다. 따라서 저자는 아직 시간적인 여유가 있을 때에 EU에서 제기한 GM과 non-GM 특히 유기 농작물과의 공존을 위한 제도 보완에 관한 제안서와 다양한 연구보고서들을 면밀하게 검토할 필요성이 있다고 사료된다. 특히 작물별로 친환경작물과의 구분 생산 유통을 위한 최소격리거리, 작부체계, 수확 및 포장시스템, 그리고 GM작물의 검출기법 표준화 등에 관한 상세한 실시요령을 보완할 필요가 있다고 사료된다.
