In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. This study closely verifies the concept of tensity analyzed in preceding studies by quantifying it through experimentation and questionnaire, and suggests possible alternatives which verified concept of tensity applies into the architectural design. It was examined how architects consider the finishing materials through a questionnaire. With a questionnaire, the possibility of quantificative analysis for tensity is evaluated by SPSS program. Moreover, a questionnaire about the social image that the architectural finishing materials have was also conducted. This questionnaire results In the actual methods to apply quantificated psychological tensity and social images into the architectural design and recommends better plan to select finishing materials for each spacial function and usage, Due to the great influence of social images in design expression, the application mechanism of the tensity should follow the general and individual principles together. With the tensity figure and application of social images we can find more resonable method for material selection.

Purpose: While medical standard is rapidly improved, welfare of users and employees in hospitals is not treated correspondingly. Intercommunication of hospital users is thought to be very important for their welfare, and provision of conversation spaces within hospital environment needs to be expanded by architectural design. Space organization methods for the design of conversation space is to be embellished. Methods: Literature and hospital designs are analysed in order to develop the basis of argumentation for the hospital conversation space. 15 hospitals are reviewed and designed spaces for the intercommunication of the users are examined, Space organization efforts and design experiments are identified, and 6 organizational methods are proposed such as: 1) reducing territoriality 2) flowing space 3) categorizing and separating spaces 4) height variation 5) contact with outside and 6) Sun-lighted space. Results: 6 organization methods are confirmed in precedent hospital cases, and these proposed methods are applied in a new hospital design project to verify their usefulness. Implications: A hospital design project is presented based on these proposed methods of organization for the conversation space. Outcomes of this study can be applied for the formulation of human intercommunication spaces in other facilities.

Daylight is an important component for human and energy saving. Also, available daylight in inside provides positive influence on psychological and physiological aspects as well as good visual environment. It is important to lighting design for office building not only designing for artificial lighting but also using daylight for energy savings. Therefore, lighting designers and architectures must consider the effects of the daylight for human environment and energy savings. The BIN Method is one of the methods to predict energy savings using computer simulation but it spends more time than expectation. So, this study performs to simulate a simple space using the RADIANCE for examination and simplification of the BIN Method.

As the development of digital and technological sophistication, architectural speculation hierarchy had been more and further diversified and brought on the changes with system of architectural color meaning. Architectural color had been influences on evocation of effect and meaning by association, had the attributes of communication with human being, in common with precision, non-verbal and non-quantitative creative field. Color could not been defined as one conclusively standard symbol and figured out in inter-relationship with correlation, mental status and interaction. Color in architecture could been promptly defined as the tool of visualization in building or structure through the essential criterion to be measured with shape, space and author's thought. In consequence, color in architecture could been re-defined as the speculation concept for real characteristics creation(color as design factors on architect and color to be expressed by program) in itself, and color supporting system as for transposition of light and space enlargement scheme. Consequently, color in architecture could been turnover from perceived color to anthropological color through the real value creation scheme in itself.

The purpose of this study was to propose the Guidelines for the Program and Space of Adult Day Care Center. Recently the Adult Day Care Center is extremely on demand caused by the increasing population of the elderly. In order to provide the affordable and efficient rehabilitation program the architectural setting should be turned to that purpose. In particular, the adult day center program must have the programs for three kinds of the elderly in terms of health status, for example, Altzheimer's disease, paralysis, and sickly elderly. Therefore this study propose the way of planning the program and spaces to give the appropriate care for Adult Day Care Center.

Purpose: The analysis of spatial composition is required for the creation of healing environment in healthcare facilities. This study has been accomplished to provide basic data for the planning and design of hospital architecture. Methods: Literature review of healing environment and investigation on characteristics of spatial composition in healthcare facilities have been conducted. The architectural plans of four Sou Fujimoto's healthcare projects have been analyzed with space syntax. Results: The result of this research can be summarized as followed. First of all, the healing environments are consisted with architectural composition in addition to physical and psychological factors for healing environment. The second one is that the characteristics of spatial composition in Sou Fujimoto's healthcare projects are different private/public/corridor relationships in program configuration, loop or one direction circulation, combined or independent corridor with program, and radical or linear connection in spatial connection methods. The third one is that the characteristics of spatial composition in selected cases through space syntax are high variation on integration, low variation on connectivity, and high distribution in main circulation on ERAM(3). Implications: In addition to the specific spatial composition in healthcare facilities of the architect's project, it is necessary to analyze the relationship with other factors and facilities to develop the planning of hospital architecture.

The objective of this study is the development of discrete optimum design algorithms which is based on the genetic algorithms. The developed algorithms was implemented in a computer program. For the optimum design, the objective function is the weight of space trusses structures and the constraints are stresses and displacements. This study solves the problem by introducing the genetic algorithms. The genetic algorithms consists of genetic process and evolutionary process. The genetic process selects the next design points based on the survivability of the current design points. The evolutionary process evaluates the survivability of the design points selected from the genetic process. The efficiency and validity of the developed discrete optimum design algorithms was verified by applying the algorithms to optimum design examples.

It is essential for vertical smart farms that artificially grow crops in an enclosed space to properly utilize air environment facilities to create an appropriate growth environment. However, domestic vertical smart farm companies are creating a growing environment by relying on empirical data rather than systematic methods. Using IoT to create a growing environment based on systematic and precise monitoring can increase crop production yield and maximize profitability. This study aims to construct a monitoring system using IoT and to analyze the cause by demonstrating the imbalance of temperature environment, which is a significant factor in crop cultivation. 1) The horizontal temperature distribution of the multi-layer shelf was measured with different operating methods of LED and air conditioner. As a result, there was a temperature difference of "up to 1.7℃" between the sensors. 2) As a result of measuring the vertical temperature distribution, the temperature difference was "up to 6.3℃". In order to reduce this temperature gap, a strategy for proper arrangement and operation of air conditioning equipment is required.
