The U.S. Department of Energy conducts the Solar Decathlon competition as a student-based achievement that encourages sustainable design with energy efficiency and solar energy technologies. In the 2020 competition, the University of Nevada, Las Vegas (UNLV) team designed, fabricated, and constructed a net-zero modular house that applies innovative and highly efficient building technologies. This paper focused on the lessons learned during the early phases of this ongoing modular project. The research methodology included obtaining feedback from key project participants using a well-structured questionnaire. The results showed that the major items/challenges in the project's planning phase included selecting the modular size, planning the construction system, planning the materials and procurement, estimating costs and duration, selecting a fabricator, collaboration and communication, safety, and planning module transportation. These findings will help modular practitioners and future Solar Decathlon competition participants better understand how and what factors they should consider most during the early phases through the lessons learned.

TOD(Transit Oriented Development) has recently been active, which presents that TOD planning elements should be comprehensively taken into consideration in order to enhance domestic transit ridership by changing environments in rail station areas and an empirical analysis on the type of rail station areas and transportation demand should be a prerequisite for usage of future development planning. This study aims to grasp a variety of TOD of influence factors in Seoul rail station area and to perform analysis to identify relationship between public transportation demand and these TOD design factors. To make it come true, we gathered data with respect to Density, Diversity, and Accessibility as representative TOD planning elements and carried out factorial and regression analysis. Consequently, we drew 7 influence factors base on factorial analysis: Factor 1(Diversity/ -Use Mix(LUM)), Factor 2(Density/development density), Factor 3(Accessibility/public transportation facility supply), Factor 4(Design/street design), Factor 5(Green/access mode (pedestrian, bike), Factor 6(Design/subway size), Factor 7(Accessibility/Public transit operation) As the result of model development by using factorial and regression analysis, positive influence factors on passenger flow in rail station area are Factor 1(Diversity : Land-Use Mix), Factor 3(Accessibility : public transportation facility supply), Factor 2(Density : development density), Factor 5(Design/ access mode) and Factor 6(subway size) Next, negative influence factor on passenger flow in rail station area shows Factor 7(Accessibility/Public transit operation) as the most influential factor. This is because the growth of service interval of linked subway and bus leads to reduced demand.

The purpose of this study was to establish the more rational and practical basic theory for the landscape planning in the aparment complex. In this study, the actual conditions of exterior space, the residens' satisfaction degree and the correlation between exterior space and the residents' satisfaction defree were investigated and analyzed on the 13apartment complexes in Taegu City. Through the statistical analysis, the main results were obtained as fellows : It was found that the size of green area ratio in the apartment complexes were in the order of Jugong Apt. (Korean Housing Corporation), Siyoung Apt. (City Operation), Minyoung high-rise Apt. (Private Business) and Minyoung low-rise Apt. (Private Business) complex. The highest ratio of footway and Parking area were shown in Minyoung high-rise Apt. complex. The important factors at the exterior space of apartment complex were composed by 6 major factors, importance degrees of which are Visual, Practical, Convenient, Sentimental, Recreational and Spatial factors for teenagers in orders. The residents' satisfaction degrees to the exterior space were highly correlated with the spatil organization, size of green area and quantity of trees, view, management situation, defensibility of outside noise, rest place, water landscapings by turns. In order to get more than the average satisfaction degree 18 exterior space, the green area should be occupied by 35% of the apartment complex area and more than 76% of the green area (i. e. 16% of the apartment complex area) should be planted with trees. In the Taegu City regulation, the ratio of tree composition is proposed for only the number of tree. But it was shown that the satifaction degree are more correlated with the species and afforestation of trees than the nuts her of trees in this study. therefore, the species of tree and the afforestation of tree should be considered when the landscape planning of the apartment complex begins. It was found that the ratio of afforestation to make the more desirable exterior space In the apartment complex shoule be 8 to 2 in the ratio of arbor to shrub. It was also required that 30 species of arbor and 15 species of shrub should be planted for the more desirable landscape of the apartment complex.

The objective of this study is to activate dining facilities by integrating the factors of space marketing. In this study, It extracts the factors of space marketing applied in the real space on the basis of precedent studies. The selection standard of precedent studies focused on the planning and strategy of space marketing conducted after 2000, and 28 factors in total 16 precedent studies were extracted. We extracted only the factors of space marketing which is applicable to dining facilities by merging and reestablishing them. The extracted 12 factors included. In this way, we conducted a survey on the factors of space marketing as well as utilization and satisfaction considered to be needed for the activation of dining facilities based on H university dining facility in Seoul. Accordingly, I collected a total of 215 copies and analyzed them by SPSS program. According to the result, it indicated that there were many students who primarily used the outside dining facilities rather than university dining facilities regarding the utilization of university dining facilities, and unsatisfactory factors included the design and size of the entrance, quality of the serving space, quality and noise of the dining space, other facilities, size and quality of the rest space and drinking fountain, snack bar, and cafe regarding the satisfaction of each space. It also indicated that the factors which influent the image of university dinning facilities the most included the marketing factors considered to activate university dining facilities such as spatial factors, sensuous factors, and environment friendly factors in order. Therefore, we can consider the interacting operation system that students primarily decorate, improve and use the spaces of the outside dining facilities and other university dining facilities. In conclusion, it's need to consider activating university dining facilities which have been responsible for only basic parts by integrating the marketing factors in common with the outside dining facilities.

There have been some research papers on financial services marketing, but there are only few exploratory studies that analyze characteristics of financial consumers in Korea. This study examines, based on FGI and web survey results, which factors consumers consider more important when choosing their financial services. I found that 'product profitability' is the most important factor when consumers choose their financial services, followed by 'relational benefits', 'convenience', 'product diversity', 'company stability', 'branch satisfaction', and 'social responsibility' in order of importance. The study also showed that there are differences in perception of these important factors depending on the types of consumers such as gender, age, size of financial assets, degree of risk-taking, and main financial company they are using. This study hopefully provide implications to marketing managers in financial services that they could decide which factors they have to focus on more when planning marketing strategies. Another objective of this study is to provide useful insights to the future researchers in financial services marketing.

Purpose: Regional public hospitals have implemented functional reinforcement projects, and the facilities to accommodate them have increased in size. Nevertheless users in hospital are concerned about space shortage and area imbalances. Therefore I will trace the factors and trends that influence the size, and derive the relationship between these and the uses' critical opinion. Methods: Among the indicators for determining the size of medical facilities, the number of beds and total floor area are the essential indicators that directly affect the composition of space and allocation of area inside the medical facility. The purpose of this study is to investigate the change and the factors of change on the these two indicators in regional public hospitals and analyze the trend of changes. Results: In accordance with support undertaking, regional public hospitals have been increased the number of chronic-based beds and expanded additional facilities such as O.P.D specialized centers, emergency centers and funeral homes for reflecting the needs of the regions and times. However, as a result of analyzing the area, regional public hospitals are growing in size mainly on the ward and O.P.D is only expanded the scope of functional reinforcement division but total area level of O.P.D is lower than the recent level. In addition, the levels of D&T, Supply, mechanical/electrical equipment area related to medical support and control environment quality are very low. This is because the functional reinforcement projects have been done without concerning diagnose the whole facility. Implications: If functional reinforcement projects are conducted, to cope with problems of space shortage and imbalance of area, it is judged that an architectural planning that comprehensively analyzes existing facilities and related departments should be included.

Studies about architectural planning for elderly residences have been carried out to examine various factors including the unit plan, site planning, and size planning. However, no studies have been undertaken that focus on the residents' daily life patterns. This study offers the design guidelines to support the daily life patterns of the elderly through the planning of elderly housing. For this study, elderly residents in Tokyo, Yokohama etc. in Japan were interviewed and surveyed. The results indicate that the changes to the daily life patterns of the residents living in elderly housing are the reduction of household, the increase of free time, and the change of social relationships. The elderly want to utilize their free time and focus on their social relationships. However, the elderly residences that we surveyed pay no consideration to social spaces and programs for their residents except for the cafeteria. To support the daily life patterns of the elderly, elderly housing should set a high value on the location, shared spaces, and unit plans of the residences in order to consider the personal diversity of the residents. Accessibility to public transportation systems and facilities should to be considered in the initial location planning. The revitalization of the public spaces should to be considered during the architectural planning stage. Considerations of personal taste during the unit planning stage are also necessary.
