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.

Polymer electrolyte membrane (PEM) electrolyzer or alkaline electrolyzer is required to produce green hydrogen using renewable energy such as wind and/or solar power. PEM and alkaline electrolyzer differ in many ways, instantly basic materials, system configuration, and operation characteristics are different. Building an optimal water hydrolysis system by closely grasping the characteristics of each type of electrolyzer is of great help in building a safe hydrogen ecosystem as well as the efficiency of green hydrogen production. In this study, the basic operation characteristics of a kW class alkaline water electrolyzer we developed, and water electrolysis efficiency are described. Finally, a brief overview of the characteristics of PEM and alkaline electrolyzer for large-capacity green hydrogen production system will be outlined.

Within green facades, the greening side of the wall is first recognized by people, leaving a visually lasting impression. As facades play a crucial factor in forming street image, their design can be considered most important. In modern days, 'patterns,' one of the popular elements of design, has developed into becoming a method of expressing architects' emotions or images as well as ways of seeking satisfaction. As opposed to recent overseas movement where patterned green facades have been widely utilized, the domestic trend still remains in outdoor green facades without patterns. This study, focusing on overseas patterned green facades, classifies the facade pattern's expressive methods into two greater parts, and four categories. Furthermore, among the elements and properties from Biophilic pattern guidelines, we specifically focus on 'Repetition Pattern,' which corresponds to 'Complexity & Order.' Biophilic design has the notion of pursuing an environment that aids modern people's comfort and well being. Providing information on patterned green facades that have largely gained popularity, this study also presents its aesthetic directions that may be applicable domestically in the future.

To ameliorate a long-standing, persistent housing shortage in Korea, large-scale massive housing production has been an imperative, and the extensive growth highly values development and consumption. The state's priority for the quantitative growth of housing stock has proved to be successful, but the state faces with economic and environmental crises in a global era. To achieve the qualitative growth, the previous administration pronounced a green growth policy from the inception, and a series of strategic measures under a holistic plan have been taken widely and vigorously. As part of the strategies, the green home project was undertaken, and simultaneously the movement of green living led by the governance has been activated. However, little attention to the grassroots effort was paid and the efficacy hasn't been adequately addressed. This study examines the factors affecting green living of residents in multifamily housing. Based on public guidelines to green living, 106 specific items were drawn out and largely categorized into 6 areas (water, waste, transportation, air quality, consumption, and energy), and the questionnaire was constructed using them. Of 750 survey forms mailed out, 161 responses were returned and the collected data were used for statistical analysis. The findings indicated that varying degrees of green living was well practiced, the state-led green home project was relatively well recognized, and the green growth policy was strongly supported. Also the respondents' attitude toward green living were more associated with demographic variables than housing characteristics, and familiarity with green home project was related to attitudes toward green living. Since the on-going approach to green living has focused on simple and economical ways, it has proved to be effective but progressive strategies to make living greener are necessarily developed.

The main purpose of the green buildings by reducing energy consumption and carbon footprint of the building society, global as to ensure the sustainability of the building and the environment. These regulations and schemes are used to activate the green buildings were made on the basis of the relevant laws and regulations. Mainly in the research for the improvement of the domestic institutional assessment items, the analysis of the legislation was fundamentally focused on Scoring the incomplete state. The analysis based on the laws and regulations of the institution is the way to know the purpose and direction of the respective certification. This study was performed in the following order to target the new commercial buildings. First, the analysis of the geungeobeop G-SEED and BREEAM. Second, we analyze the content and method of building energy performance in the certification system. As a result, Green Building Act is broad in relation to the composition of the contents are building for the activation energy green building and EPI is dealt with in an abstract and presented the applicability of such documentary content of insulation and airtightness, efficient machine. In contrast, the UK has been directly limit the carbon footprint of buildings in the Building Regulations Part L and evaluate them in BREEAM. This analysis of the ways to reduce substantially the energy for domestic green building regulations should be addressed through the feed.

This research aimed at measuring Park and Green Satisfaction (PGS) using subjective indicators of 'surface, line and spot' green evaluated by citizens. Also frequency of visits to park and green measured using objective indicators (number of visits) to find the relationship with PGS. A conceptual model of PGS was developed to relate evaluation to satisfaction and finally to utilization of open spaces. A sample of 500 questionnaire survey was employed for Uijeongbu City in Korea. A Structual Equation Modeling (AMOS) techniques was used to test the hypothesized relationship among factors (construct). As a result, first, PGS was explained by three latent factors of 'urban park' (${\gamma}=0.54$), 'linear facilities' (${\gamma}=0.25$), and 'surface green' (${\gamma}=0.15$) respectively. These three exogenous construct was found very useful classification system for open spaces of cities. Second, PGS (${\gamma}=0.34$) was found as a mediating variable to utilization of open spaces and also PGS was closely related to citizens Environmental Quality Satisfaction (EQS), such concept as, 'livability' and 'aesthetic quality'. The more satisfied with park and green the more people use the space. The PGS was an important QOL indicator together with the subjective indicator of 'livability'. Third, jogging and walking trails and bike ways along the river corridor was the most important green facilities contribute to the PGS and EQS. The near the distance (within 500m) the more number of visit to river corridor (green way). The river corridor promote accessibility to nature and other parks.

This research is to establish a theme-type organic edu-farm model and provide ways to practically apply it so as to vitalize urban-rural exchange through the emerging concept of green tourism. This research also traces the practical development of organic edu-farm programs. Organic edu-farm(OEF) should be some of the ideas to develop organic agriculture resources according to the local features, and learn by direct and actual experience a life of organic farm. A few policy suggestions to put OEF model in practical use are proposed. What the state needs to do through direct involvement are to put efforts at demand expansion on organic farm products, to clean and beautify the green rural environmental settings, to build more urban-rural exchange facilities. What is more important, however, is financial support, to create the network and to develop program contents for each OEF operation unit. The OEF model proposed in this research will be applied as a relevant reference in planning and realizing sustainable green tourism at the village level.

As a green construction is a world-wide hot issue, Korean government is also putting forth a multilateral effort into reducing energy usage with setting aggressive goal under green growth policy. It is essential to analyse cost raised from designing and building green construction and benefit derived from the built facility for the sustainable green construction. However, compared to advanced countries in terms of green construction, there is lack of data and a systematic way for data collection and analysis in Korea. Without analyzing the cost-benefit of green construction, investors will hesitate to put his/her money into green construction and we can not expect its growth in construction industry. In this paper, cost of green construction was defined and categorized. Through case studies and various reports on cost-benefit analysis in advanced green construction countries, problems in terms of data collection and analysis in domestic green construction sector and improvement ways were suggested. The results of this study will contribute in classification of cost and benefit of green construction, data collection in systematic way, and increasing the feasibility of green construction via appropriate analysis on cost-benefit of green construction.

The goal of this study is to deduce the image of city people on rural district, and to clarify the city people's demands on rural tour and their consciousness on green tourism. This study also aims to propose the effective ways of improving the environment of rural district to revitalize green tourism and to promote the exchange between urban and rural districts. The study results indicate that most city people have a warm-hearted lyric image on rural district. In addition, it is indicated that the city people like the rural district with beautiful scenery, which is easy to contact with nature. On the other hand, as the goal of green tourism, in addition to the contact with nature, the exchange between urban and rural districts and the understanding on the rural life through personal experience are also considered very important. Finally, the city people are classified into four types, and it is necessary to develop the green tour program with emphasis on the city people of overall-type.
