The existing building code regulates the minimum distance between buildings and the minimum required sunshine hours for winter solstice to ensure the right to light. Especially, the minimum sunshine hours have been guaranteed by the constitution after the right for the people to live in a healthy and comfortable environment was established. However, the existing regulation on the sunshine hours only considers the duration of sunshine hours, but ignores the minimum amount of sunlight. Therefore, the calculated sunshine hours are not coincident with the hours occupants actually feel. Therefore, the purpose of this study is to investigate the effect of solar incident angle on interior illuminance distribution, which will be used to propose a new code on the minimum sunshine hours and levels.

Since 20th century, the exhibition has expanded to more diverse fields and recognized as the medium which can build network among the Art, Human and society. Space design, although developed within mutual interaction and consideration of environment factors, has been treated without those background. Therefore it is straightforward to examine the exhibition space design synthetically not limit it by the analytical elements. Assuming three main mutual interactions, object human, and environment, we have attempt the typological analysis to the museum exhibition space by studying characteristics. While the exhibition space design has been analyzed through two dimensional interpretation, on this study, we structuralize diverse discussion of the exhibition space design by relation-centered and relative analysis. Therefor we examine the characteristic of design expression through typology of both physical and behavioral feature. In the conclusion, the outcome provides insights into the relationships among object, human and environment and useful measurements to designer who outline exhibition space design.

This study aims to conduct an empirical analysis on the impact of service quality (performance work, price, physical environment) on customer satisfaction, trust and intention to re-attend ballet performances. Another focus of the research is to examine the structural effect of satisfaction and trust on customer's intention to re-attend. This study surveyed 240 adults (Americans) who have physically attended ballet performances from 2019 to 2020. Applying the structural equation modeling analysis using the software SmartPLS, this study investigates 240 valid responses obtained from a global research institute in a mid-August 2020 survey. The findings of the analysis are as follows. (1) Performance work is positively correlated with customer satisfaction, while price and physical environment do not affect customer satisfaction. (2) Performance work is positively correlated with customer trust. However, price and physical environment haven't been observed to affect customer trust. (3) Customer satisfaction is positively correlated with customer trust. (4) Performance work, price and physical environment do not affect customer's intention to re-attend ballet performances. (5) Customer satisfaction is positively correlated with customer intention to re-attend performances. (6) Customer trust is positively correlated with the intention to re-attend performances.

An effective design of a public space that properly functions as a resting place in city can be found through the community facility studies. This study, based on the ecological psychology, discusses the mutual relationships between human behaviors and physical and social environment. It is demonstrated that design elements, such as chairs, tables, stairs, a flower bed, a stair-shaped exterior wall, a pond and others play important roles in providing environment for different human behaviors in public space. These environmental design elements also increase a variety of behavior for users.

It has been considered that fishing areas for shrimp beam trawl have been in ruin because Korean local governments have permitted trawling into the areas limited by the fisheries local regulations from 1994. Physical and biological effects of the trawling were investigated in the study. Physical effects were investigated by optical methods such as trawling tracking by side scan sonar and comparing the gear both before and after trawling. Biological aspects were investigated by grab sampling of benthic animals, concentration of trace metals in sediment and a flux evaluation of ${NH_4}^+,\;{PO_4}^-,\;and\;SiO_2$ by coring. The fishing activity had physical impacts on the seabed but these recovered naturally in less than fourty days naturally, which increased the benthic biodiversity, increases the trace metal concentration of and nutrient flux into the seawater, especially phosphate and silicate. This method and these results can help in further studies looking for disturbances by fishing.

Sensor network supports data delivery from Physical world to cyber space. Sensors get physical events then wireless network transfers sensor data to service server. We use sensor network technology to light control system for intelligent building. In ubiquitous computing environment. wireless sensor network is basic tool for intelligent service. In this paper, we propose intelligent building light control system based on wireless sensor network. It is implemented using previous light control product, can be adopted to present building light system.

Infiltration facilities are effective instruments to mitigate flood and can increase base runoff in urban watersheds. In order to analyze effects of infiltration trenches physical model experiments were conducted. The physical model facility consists of two soil tanks, artificial rainfall generators, tensiometers, and piezometers. The experiment was conducted by nine times and each case differed in rainfall intensity, rainfall duration and the type of ground surface. Measured quantities in the experiments are as follows: surface runoff, subsurface runoff, trench pipe runoff, groundwater level, water content, etc. The following resulted from the model experiment: The volume of subsurface runoff at trench watershed was maximum 78.3% compared with rainfall. This value is bigger than that of ordinary rate of subsurface runoff, and shows a groundwater recharge effect of trench. The time of runoff passing through the trench became earlier and the volume of runoff became larger with the increase of inflow into the trench, while trench exfiltration into ground became relatively smaller. The results of this study presented above show that infiltration trenches are effective instruments to increase base runoff during dry periods.

We study empirically analyzed the final 216 copies of the responses from SME organization members in Seoul and Gyeonggi regions using statistical programs of SPSS24.0 and AMOS 24.0. In other words, the effect of job satisfaction on the organizational culture and job environment characteristics perceived by members of the organization, and the relationship between job satisfaction and job performance is shown as follows. First, the organizational culture of consensus, development, hierarchy, and rationality was statistically significant in job satisfaction. Therefore, the hypothetical one-man organizational culture was adopted by showing a positive (+) effect on job satisfaction. Second, job environment characteristics such as autonomy in job performance, compensation system, physical environment, and human environment had a positive effect on job satisfaction. That is, the job environment characteristics of hypothesis 2 were adopted as a positive (+) influence relationship on organizational satisfaction. Third, job satisfaction was expressed as a positive (+) influence relationship with job performance, so hypothesis 3 was adopted. As a result of this study, the higher the organizational member's perception of organizational culture and job environment characteristics is, the higher the job satisfaction is, and the improvement in job satisfaction is meaningful in that it provides theoretical and practical implications that indicate job performance.

Investigating the physical and chemical properties of riverine wetlands is necessary to understand their distribution characteristics and depositional environment. This study investigated the physical (particle size, color, and type) and chemical properties (organic, inorganic, and moisture contents) of sediments in Samrak wetland, located in the Nakdong River estuary area in Busan, South Korea. The particle size analysis indicated that the hydraulic conductivity values for the coarse grain and the mixture of coarse and fine grains ranged from 2.03 to 3.49×10^-1 cm s^-1 and 7.18×10^-3 to 1.24×10^-7 cm s^-1, respectively. In-situ water quality and laboratory-based chemical analyses and radon-222 measurement were performed on groundwater and surface water in the wetland and water from the nearby Nakdong River. The physical and chemical properties of Samrak wetland was characterized by the sediments in the vertical and lateral direction. The concentrations of chemical components in the wetland groundwater were distinctly higher than those in the Nakdong River water though the wetland groundwater and Nakdong River water equally belonged to the Ca-HCO₃ type.

In Korea, the global warming leads to more frequent high temperature region. increasing the need for research into physical damage caused by high temperature. We therefore analyzed the differences of mortality, caused by extreme heat, among gender and age. We also examined the trend of mortality from high temperature-sensitive diseases. Women are more affected by exposure to high temperature than are men; People over 65 years old have higher mortality rate (1.5 times) than under 65. As for high temperature-related diseases, cerebrovascular disease was the number one cause of death, and chronic lower respiratory disease and cardiovascular disease followed.
