  • ALC was fabricated using cement, lime and quartzite by hydrothermal reaction. The kind of quartzite was reviewed for ALC properties and returned slurry was recycled in this study. Munkyung and Kumpyung quartzite was used and quartzite powder was experimented. The major mineral phase of Munkyung quartzite was quartz and muscovite crystal but that of Kumpyung was quartz. It was certain that crystallinity of Kumpyung quartzite was superior to Munkyung quartzite. Compressive strength and A-number of ALC with Kumpyung quartzite was higher than that of ALC with Munkyung quartzite under similar specific gravity. These results was resulted from major mineral phase, crystallinity and minor components of quartzite.

  • Green Frame was developed to embody a Green structural system that can provide long life, resource reduction, and availability of remodeling in apartment buildings. Composite precast concrete column and beam, the major structural material of Green Frame, can be installed precisely and promptly through connection of steels and concrete. The connection of Green Frame can be divided into four types, based on the method and characteristics of connection. To select an appropriate type for the site, a comparative analysis of the four types is necessary. The objective of this study is to compare the duration, cost, quality, and safety of four types. The findings of this study can be applied during the selection that appropriate composite precast concrete column reflected project characteristics in design phase.

  • USGA green specification is currently accepted in construction method of Korea. This study was carried out to find the factors influencing growth of turfgrass associated with soil physical properties of soil root-zone on golf green constructed with USGA method. Three putting greens in poor turfgrass and one in good turfgrass condition were selected for investigation on one golf course site at mid-South Korean peninsula. Soil hardness, moisture content, root length, and turf density were measured on-site greens, and soil physical properties and soil chemical properties also analyzed in laboratory. As a result of on-site surveys and soil physical tests in laboratory, soil physical properties were most important factors which influenced on turfgrass growth at tested greens. The results of soil particle analysis on green No. 2, in good turf condition, matched USGA sand particle recommendations. But those greens such as Nos. 1, 11 and 16, in poor putting greens, showed high soil compaction and improper soil particle distribution. Those factors created low leaf density, poor root depth, and higher moisture content compared with lower part of topsoil. Such phenomena caused inadequate turfgrass growth with soil hardening associated with poor drainage. Therefore, declines of soil physical properties associated with improper particle distribution caused a major factor influencing on turfgrass growth in golf green. Adequate test of soil particle analysis by USGA specification and proper construction method followed by adequate turf maintenance should be performed to obtain optimal turf quality on putting green.

  • Green Building Certification Program, which was first introduced to residential buildings in Korea in 2002, has been put on track. This program is expected to bring about the effect in the economic viewpoint that was based on a life-cycle-cost analysis, not to mention the environmental viewpoint. However, given the fact that the existing model for feasibility analysis focusing on early investment cost can hardly be applicable to the green buildings because of lacking the life-cycle-cost reduction factor, it remains still difficult to conduct an objective evaluation. The study thus was intended to identify the factors that should be additionally considered in conducting the feasibility study to be implemented through the analysis of the certification items of green buildings as a preliminary study in structuring the evaluation model for feasibility analysis of green buildings.

  • At present, there are a lot of theoretical studies on the theme of tea industry brand construction, but in the survey, it is found that the theory that can study the tea industry brand from the perspective of brand equity is extremely lacking. This paper takes Rizhao Green tea as the research object, focusing on the influencing factors of Rizhao Green tea brand equity from the perspective of consumers and the relationship between various factors. The results show that the brand equity of Rizhao Green tea is composed of brand awareness, regional association, quality perception and brand loyalty. There is a certain correlation between each dimension and has an impact on brand equity. There is a significant correlation between brand awareness and regional association. Brand awareness has no significant impact on quality perception. Regional association has a significant positive impact on quality perception and brand loyalty. Brand awareness and quality perception have a significant positive impact on brand loyalty. The research results can provide theoretical basis and practical guidance for the construction of Rizhao Green tea brand assets while making up for the lack of theoretical research in this field.

  • Due to economic or environmental reasons, green remodeling projects for old buildings are being actively carried out. Meanwhile, in the process of performing the green remodeling, the plan of green remodeling including passive and active elements has been decided based on the subjective experience and knowledge of engineers currently. Therefore, in this study, an ontology-based green remodeling decision-making support model, which can analyze the properties of old buildings and suggest appropriate remodeling plans, was established. In the developed model, once the basic properties of a building are entered, an appropriate remodeling plan composed of passive and active elements can be provided. By utilizing the results developed through the research, it is expected that it will be possible to support decision-making on more objective and appropriate remodeling alternatives development through web-based meta data search in accordance with the accumulation in remodeling cases.

  • The proper use of the passive and active design elements are important for the realization of green buildings. The G-SEED (Green Standard for Energy and Environmental Design) has been implemented in Korea to promote green building construction reflecting these design elements. In this paper, evaluation items of G-SEED which related to the passive design were selected. And improvement direction for the G-SEED was proposed through the analysis of the application status of the passive design elements for the G-SEED certified buildings. This results can be used for developing study on the future improvement of the assessment criteria of G-SEED.

  • Recently, the housing market in Korea has been changed from new construction to building-stocks, and focusing on supplier to focusing on users. Open housing is a design method not only content to users' various needs but also to the means of sustainable development by adapted to longevity of buildings. There are some indicators for Open Housing related to Green Building Certification Criteria which were worked by Mock & ME. But those indicators are limited to flexible design methods. This is a basic study for the selecting of Open Housing indicators for complementation of Green Building Certification Criteria by the analysis of SI housing in Japan, domestic Green Building Labelling and those of other countries.

  • To promote environmentally responsible architectural practice, many nations have established their own Green Building Certification system. Until 2007, 138 Education facilities acquired certification but many people don't fully understand each item of Green building Certification Criteria yet. The purpose of this study is to analyze 40 certified Education facilities and to find the reasons why they had acquired low scores and high scores. These scores lead us to propose a way that each contents the efficient approaches and alternative visions of Education facilities. Because the part of material and resource is initial of the projects, this study focuses on it and aims to pick out the items requiring improvement for the Education facilities. We expect to be helpful for the next design works through result of this thorough study.
