Current supervision systems have been changed by the demands of social, physical and institutional environment, and have a role of preventing safety accident and in improving the construct ability through the analysis of issues in quality, time, construction, safety, and environmental management. The public sector "Construction Technology Management Act", a general and private sector "Building Act" and "Certified Architects Act", the residential building "Housing Act" are dealt with supervision systems, respectively, but private small building construction is excluded from the discussion of the main targets because of their relatively small scale and the lack of social interests, Thus, this study focused on the small buildings for improving the non-resident supervision systems. Survey results revealed that the non-resident supervisor needs to be selected not by clients but by officers in order to obtain its publicity. Based on the proper selection and execution of the supervision system suggested in this study, the potential effects can be summarized as 1) recovering of publicity, 2) correcting abnormal practice, and 3) realizing design intention for increasing the public value of buildings. In addition, findings in this study will be effective to amend current non-resident supervision systems for improving the quality of buildings and communities as well as for adopting the environmental-friendly energy-efficient smart building technologies.

Up to date, the majority research on the major landscape elements in organic farming has been mainly focused on the practice of seeking efficiency. The problem is that this type of study contributes to polluting the agricultural environment and damaging the ecological circulation system. As an alternative, there is a growing body of research on organic farming, but it is not widely applied that research on how to manage the landscape considering the scenic characteristics of farming villages practicing organic farming. Hence, in this paper we utilized landscape adjectives as a way to enhance the objectivity of the organic agricultural complex landscape assessment. More specifically, not only this study used a landscape image of an organic agricultural complex to identify a landscape adjective suitable for the landscape elements but also this study confirmed the suitability of landscape adjectives comparing to the opinions of experts and the public. To carry out, this study performed the experts survey which is composed of 12 major landscape elements, including rice paddies and fields, monoculture and diverse crops, dirt roads, windbreak trees, accent planting, dum-bung(small pond), natural small river, natural waterways, plastic film houses, one-storied houses, and pavilion. As a result of deriving the landscape adjectives from the main landscape elements, there were nine landscape adjectives that were consistent with experts and the public, including "clear" and "Artless" for rice paddies and fields, while the mismatched landscape adjectives were 'traditional'. The accent planting was a combination of landscape adjectives such as 'natural' and 'clear', while the windbreak trees was a consensus of all landscape adjectives. Only two adjectives, 'friendly' and 'wild', agreed on the dirt load, nine dum-bung(small pond), ten natural small river, nine duckery, eight one-storied houses, 10 pavilion, eight monoculture and diverse crops, and three natural waterways. The most common landscape adjectives were windbreak trees, pavilions, and natural small river, all 10 landscape adjectives. However, it is considered that only three of the 10 landscape types on the dirt road and the natural number are matched. Thus, additional management measures will be needed. In addition, it was analyzed that the most common landscape adjectives were "Artless" and "friendly" 13 times. The landscape adjectives of the organic farming complex responded by experts were analyzed to be suitable for natural, clear, zingy, silent, traditional, artless, friendly, wild and Leisurely, and consistent with the general public's opinion.

Energy saving and environment-friendly dyeing method of cotton with reactive dyes is the ultra low liquor ratio dyeing because it reduces the total quantity of water, dye, salt and alkali during the dyeing process in the effluent as well as the energy consumption. However, this method may not guarantee the quality of the dyeing results due to the specs or unlevel dyeing depending upon the dyes used. The study has focused on the effect of leveling agents in the dyeing of cotton with reactive dyes under the ultra low liquor ratio (1:5). Especially Sunfix N/B MF-D which was selected for ULLR showed low-leveled dyeing comparing with the other MF-D series. A leveling agent having polycarbonate structure increased LDF values of Sunfix N/B MF-D without changing of dyeing fastness. We recommend some leveling agents to improve the leveling behavior for ULLR dyeing.

Modern society is filled with the pursuit of material wealth and great convenience due to high technology that has been introduced to all facets of society. There is no exception to this in the field of construction. Modern construction, however, has caused environmental destruction and pollution, disturbing the coexistence of humans and nature. Therefore, this thesis aims to explore how humans and nature can maintain a mutually beneficial relationship by looking into the construction of Jeju's traditional dwelling house. This thesis examines the geographical features of Jeju and looks into how Jeju people have adapted themselves to nature. It is assumed that geographical features have created Jeju's unique environment and style of architecture and differentiated Jeju's traditional houses from those of other regions. Also, it is considered that geographical features had a large impact on traditional construction such as the floor plan and the layout of buildings. Accordingly, this thesis explores the way traditional houses protected house dwellers from the natural environment and examines the wisdom of our ancestors who took advantage of the natural environment. In addition, this thesis aims to contribute to creating Jeju's unique construction culture and environment by studying materials, structures, and forms that were applied to the traditional houses of Jeju.

Purpose: In this study, we revealed the influence of customer buying factors in the purchase process of eco-friendly product. Especially, we focused on the information acquisition, alternative evaluation, and after-purchase activity process based on Korea-China customer's survey. Methods: In the information acquisition process, we investigate the channels of information acquisition about eco-friendly product, a reliability of information, and an impediment of acquiring product information. At the stage of alternative evaluation, we extract various causes that affects pre-purchasing process and perform the AHP analysis to identify critical causes. At last, we compare several factors which affects before and after purchasing process. Results: Especially, an average utilization and cognition score of eco-friendly products of Chinese consumers is higher than Korean consumers' score. In addition, critical buying factors of Korean consumers are a product quality, an evaluation of existing users. However, that of Chinese consumers are safety of products and environmental benefits of products. Conclusion: In recent years, as the rapid economic development of China, environment pollutions like heavy smog and yellow dust have been occurred frequently. In that manner, Chinese consumer's environmental consciousness is rapidly increasing; not only try to be active participant in eco-friendly activities, but also eco-friendly purchasing activities. In addition, Chinese consumers recognize eco-friendly products as good products made with advanced technology.
