The facade in the street is a unfixed type, thus it is not easy to investigate the characteristic of structures. In addition, a color mainly depends on sensitivity, therefore, it is very difficult to provide the solution of the problems. The purpose of this study is to investigate the relationship between a form of the facade and a color, and to introduce the methodology and the direction of the color scheme for the facade in the street. for the purpose of this study, 47 facades are empirically analyzed. Based upon the results of research analysis, this study try to find out the relationship among the formative continuity of the facade in the street, a color, and the quality of the material. From the results, it suggests the new direction for the image formation of the facade in the street centering around a color. This study concludes that the characteristics of the facade in the street is discontinuous, and the color scheme is not based on the formative continuity. Moreover, the whole street is composed of each strong individual character. In order to harmonious creation of the facade in the street, primary colors and painting colors should be constrained. Finally, the color scheme based on the formative continuity of the facade in the street should be carefully considered.

This paper reviews the structures, physical and chemical properties, origins and global distribution, amount of energy resources, production technologies, and environmental impacts of gas hydrates to understand the gas hydrates as future energy sources. Hydrate structures should be studied to clarify the fundamentals of natural gas hydrates, hydrate distributions, and amount of energy sources in hydrates. Phase equilibria, dissociation enthalpy, thermal conductivity, specific heat, thermal diffusivity, and fluid permeability of gas hydrate systems are important parameters for the the efficient recovery of natural gas from hydrate reservoirs. Depressurization, thermal stimulation, inhibitor injection, and chemical exchange methods can be considered as future technologies to recover the energy sources from natural gas hydrates, but so far depressurization is the only method to have been applied in test productions of both onshore and offshore hydrates. Finally, we discuss the hypotheses of environmental impacts of gas hydrates and their contribution to global warming due to hydrate dissociation.

This study investigates the effects of restaurants' physical environments on customers' words of moth and return intention. Data was collected using a self-administered questionnaire from restaurants during summer of 2020 and received 627 useful responses. The data was analyzed using the hierarchical multiple regression. The results showed that restaurants' physical environments was statistically significant influencing factors on customers' positive word-of-mouth and return intention. Hygiene environmental variables did not moderated the relationship between restaurants' physical environments and customers' word-of-mouth whereas hygiene environmental variables did moderated the relationship between restaurants' physical environments and customers' return intention. The results of this study suggested that restaurant business owners need to maintain clean environment and to continuously educate employees to protect customers from COVID-19 spread.

다수고객을 서비스하기 위한 설비의 입지선정문제는 현 기업환경 하에 많은 분야에서 광범위하게 응용되고 있다. 본 논문은 경쟁사 설비가 기 입지해 있는 상황에서 시장점유율을 최대화하기 위해 정해진 수의 설비를 주어진 입지후보지에 설치하기 위한 입지선정문제를 다룬다. 고객은 도시공학 분야에서 잘 알려진 4개의 도시공간구조 이론에 근거하여 분포시키고, 고객의 수요를 최대로 충족시킬 수 있는 매장의 입지를 선정한다. 실험을 통해 각 도시 공간형태별로 상이한 고객의 분포형태와 계층별 거주지역의 밀집도가 매장의 위치에 미치는 영향을 확인한다. 또한 입지선정문제는 잘 알려진 NP-hard 문제임에 따라 합리적인 시간에 근사 최적해를 도출하기 위하여 유전자 알고리즘을 적용함으로써 기업의 입장에서 이윤을 극대화하는 최적의 설비위치를 결정할 수 있는 모델을 제시하였다.

우리나라에서 다른 광물자원보다 매장량이 비교적 풍부하고 에너지원으로서 총에너지소비량에서 중요한 몫을 차지해 온 석탄의 희소성을 측정하기 위하여 시장가격을 사용할 경우 그 결과는 실질고갈상태를 왜곡시킬 수 있다. 왜냐하면 정부가 석탄가격을 관리하며 생산원가보다 낮은 부분에 대해서는 보조금이나 장려금을 지급해 왔기 때문이다. 그러므로 본 연구는 쌍대성이론(duality theory)을 토대로 한 할버슨-스미스(Halvorsen-Smith, 1984) 모형을 이용하여 매장되어 있는 광물자원의 암묵가격(shadow price)을 실증적으로 추정함으로써 우리나라 석탄자원의 희소성을 측정하였다. 최종생산물의 가격으로 측정된 희소성지표에 의하면 우리나라의 석탄자원은 매우 완만하게 고갈되어 가고 있는 반면에 광석의 암묵가격으로 본 회소성지표에 의하면 그보다 더 빠른 속도로 고갈되어 가고 있음을 알 수 있었다.

상품의 매출은 진열 환경에 크게 영향을 받기 때문에 백화점을 비롯한 각급 매장에서는 다양한 연구를 진행하고 있다. 특히 조명에 따라 의류나 가구는 물론이고 과일을 비롯한 식료품의 매출액도 많은 영향을 받는 것으로 알려져 있다. 이에 따라 어떤 색상의 배경이나 조명이 소비자의 주목을 끌고 호감을 줄 수 있는지에 대한 연구들이 디자인 학자들을 중심으로 이루어지고 있으나, 실제 매장에서는 상품 색상에 맞춰 배경이나 조명을 변경하는 것이 거의 불가능한 실정이다. 따라서 본 연구에서는 상품 색상별로 소비자의 주목을 끌고 호감을 이끌어내서 상품 구매로 이어질 수 있는 IoT 기반의 스마트 LED 조명 시스템을 아두이노 보드를 이용하여 구현하고자 한다.

스마트폰의 확산과 함께 소비자들의 소비 환경과 행태가 변화하면서 기업은 온라인과 오프라인을 연계하는 O2O 서비스를 제공하고 있다. 기존의 O2O 서비스는 제품 정보를 기반으로 온라인 쇼핑을 제공하고 있으나 온 오프라인 매장 간의 연동에 한계가 있다. 이에 본 논문에서는 온라인 쇼핑몰, 오프라인 매장을 통합하여 상품에 대한 정보 제공과 제품 판매 서비스를 제공하기 위해 스마트 피팅 시스템을 활용한 O2O 연계시스템을 제안한다.

In Korea, most of the locations of the cemeteries and burial vault are in forest lands. The utilization of forest land for this particular purpose is very inefficent and considered to be a serious problem. National government (Forest Service), local governments (Incheon city), and religious corporation (eunhoe Temple) are creating new burial methods to solve the inefficiency in forest utilization. In this study, awareness of Koreans and Japaneses on tree burial problems were compared. Based from the results of the survey, more than 80% of the respondents are aware of the problems. However, the burial culture in Korea still has many problems. Operation and management of tree burial is not being done by experts and sufficient information regarding to this type of burial still needs to developed. To solve these problems, eco-friendly burial, which is considered as new funeral culture, is now being created. In the case of Ichinoseki City in Iwate prefecture in Japan, improving the residential environment greatly affected the tree burial practices. This town was chosen for this study due to its characteristics of being a tourism area which greatly affecting the economy of this town. Another study site of this study was located in Sangju city. The changing social environement and the perception of the people regarding on the services being provided to the people were examined thru questionnaire survey. Specifically, this study analyzed the practices and beliefs of the people regarding the tree burial culture.
