Indoor noise environment is an important factor when it comes to occupants comfort, especially in cafe. Results of the survey, 33.9% of occupants were feel unpleasant and sensitive about noise environment. Noise in cafe fluctuate depending on the finishing of both wall and ceiling, volume of the room, and the number of occupants in the room. Therefore, the noise meter device was used for measurement of various under conditions. Also, the subjective assessment of occupant noise was conducted through questionnaires. When the interior finish was exposed concrete, the maximum value of the noise measurement was 66.6 dB and the minimum value was 63 dB, respectively. Also, the result of subjective assessment of unpleasant noise were 5.43 and 4.96 point of 10 point of noise and echo, respectively. Otherwise, the interior finish was gypsum board, the maximum value of the noise measurement was 73.8 dB and the minimum value was 60.4 dB, respectively. Also, the result of subjective assessment of unpleasant noise were 3.88 and 3.95 point of 10 point of noise and echo, respectively. The results of the study showed that the noises and echoes in the cafes were lower than when did not.

Growth in population and urbanization has progressively increased the loading of pollutants from nonpoint sources as well as point sources. Especially in case of road regions such as city trunk road, national road and highway are rainfall and pollutants runoff intensive landuses since they are impervious and emit a lot of pollutants from vehicle activity. This research was conducted to investigate the nonpoint sources concentration and quantifying stormwater pollutants which are contained in rainfall runoff water. Three different monitoring sites in Jinju and Changwon city were equipped with an automatic rainfall gauge and flow meter for measuring rainfall and the volume of rainfall runoff. In the case of average EMC value, city trunk road was shown the highest value in target water quality items like as BOD, COD, SS, TN and TP. Or the amount of runoff loads by water quality items showed the highest value in city trunk road. And runoff load in city trunk road was 43.8 times high value compared to highway by value of city trunk road $356.7 mg/m^2$, highway $8.150 mg/m^2$, national road $19.99 mg/m^2$ in the case of BOD.

The natural environment of the modern society does not simply reflect damage, but is a complex and grave reality that threatens the Earth. To solve this problem, various aspects related to the natural environment have been explored around the world, and a number of studies are ongoing to balance the development and preservation of the natural environment in Korea. However, no clear category exists for the natural environment and the related terms are ambiguous, rendering the overall evaluation system is in efficient. Therefore, the present study attempted to set the scope of application of a comprehensive evaluation system based on terms similar to the natural environment, concepts of the natural environment viewed from a value-based perspective and a capacitive perspective. In addition, by examining the concept of ecosystem services, a conceptual model for efficient application of the evaluation system of the natural environment through the association between categories of the natural environment is presented to derive implications for practical operation in the future.

The goal of current study is to carry out comparative analysis on the relationship between nature perspectives and their corresponding utilities by taking integrated approach combining economic values with environmental ones. The results are as follows. First, empirical evidence shows that the structures of happiness function differ according to nature perspectives. The anthropocentric-nature perspective is centered on economic value. Whilst, environment and social trust play an statistically insignificant role in deciding happiness levels. Secondly, the eco-centric perspective possesses a multi-facted structure of happiness function composing of income, environment, and social trust. In this vein, it is no reasonable behavior, from happiness maximization view, to focus on economic value vis-a-vis use value.

Up until the mid-90s, the housing market of Korea has been supplier-oriented with the constant shortage of housing supply. But today, with the surplus of supply over demand and ever-increasing competitiveness in the housing market, understanding consumers needs have become one of the keys to successful business. Consumers overall living standard have increased and they are now looking for better living environment. As a matter of course, there have been much studies focusing on the evaluation factors and consumers preferences of the living environment, somewhat overlooking the asset value of a residential property. Consumers see their house in terms of both a living space and an asset. Therefore, it is these two values altogether that influences the buying decision process of consumers. This study seeks to stress on the importance of the fact that it is both the living environment and asset value of a house that are considered in the buyers valuation of residential property. And the study suggests that influencing factors of housing attributes in the decision-making process of buyers be sub-categorized into two broad groups, value as a living space and value as an asset. This is to serve both the researcher in the academic field and marketers for better understanding of consumers needs and influencing factors of buyers valuation of housings vis-a-vis market.

Soil was regarded as infinite resources but recently, soil is considered as invaluable resources that we need to protect and conserve. Main objective of this research was to evaluate soil value in terms of soil carbon contents. Soil was classified into forest, paddy, upland, and grass. Carbon contents in each soil was calculated based on soil chemical properties. Calculated soil carbon contents was ranged $15.31-108.86mg\;kg^{-1}$. Based on soil carbon contents, soil value was assumed adapting economic concepts. Calculated total soil value based on soil carbon contents was about 18.46 trillion won. Among others, carbon contents in forest was the highest and value was assumed 11.95 trillion won followed by paddy field (3.7 trillion won).

The objective of this study is to analyze the value of attributes of agricultural products in school food service using hedonic price model and choice experiment. In the case of potatoes, bean sprouts, and tomatoes, environment-friendly agricultural products rather than conventional ones, and domestic price premiums exist rather than Chungnam. The higher the price, the higher the margin rate. Conventional agricultural products were more profitable than environment-friendly ones, and domestic products were more profitable than Chungnam. In consumer preferences, environment-friendly agricultural products are preferred over conventional agricultural products and local products (Chungnam, Cheonan, Asan) rather than domestic ones. This is the opposite result of the Hedonic price model estimation that Chungnam has a lower price premium than domestic in the case of origin. This study is meaningful by analyzing the attribute value of agricultural products used for school meals in Chungnam and comparing them with the willingness to pay consumers. With the results of this study, it is necessary that discussions on supplementing the value of local products used in Chungnam school food service.

The purpose of this study is to investigate the structural relationship between resort selection attributes, emotional responses, and empirical values of scuba diving participants. The general population who enjoys scuba diving in Korea was selected as the population. Using the convenience sampling method, 553 of the 600 questionnaire samples were extracted as the final valid sample. For data processing, frequency analysis, exploratory factor analysis, and Cronbach's α test were performed using SPSS 23, and confirmatory factor analysis and structural equation model analysis were performed with AMOS 18. The results are as follows: First, among the sub-factors of selection attributes, equipment, facility environment, and diving point showed a positive effect on emotional response, but staff service did not have any significant effect. Second, the emotional response positively affected by the selection attribute showed a positive effect on all factors of service excellence, consumer utility, fun value, and aesthetic value of empirical value. Therefore, scuba diving resort managers must recognize the importance of equipment, facility environment, and diving point among these selection attributes of customers. And to satisfy the customer needs the resort must accurately identify the needs for diving equipment, facility environment and diving point. Various methods for this should be explored through the needs of the identified customers, and efforts should be made to provide safe equipment, comfortable facilities, and various diving points.
