Throughout the modernization which was dominated by development theory in Korea, land use planning for housing tended to spoil the environment. Numerous studies, however, pointed out the problem of this development-led planning and there was a broader consensus that the past planning was part of the environmental problem of inner city. These observations changed the development-led planning into the environmental friendly development planning. In particular, Seoul Metropolitan Government held the international planning competition to develop 'Sangam' as an environment friendly residential area. With this plan 'Sangam' would be the sustainable residential area with the harmony of nature, human and technology. Furthermore it would be the outset of the long-term plan to develop 'Seoul' as a 'gate-city, an 'information-city' and an 'eco-city'. To do this, it needs especially the planners' and the constructors' constant concerns and efforts as well as the citizen's participation.

Recently, quantitative and repetitive inspections of the old urban area were conducted because many structures exceed their designed lifetime. The health of a building can be validated from the condition of the outer wall, while the slant angle of the wall widely serves as an indicator of urban regeneration projects. Mostly, the inspector directly measures the inclination of the wall or partially uses 3D point measurements using a static light detection and ranging (LiDAR). These approaches are costly, time-consuming, and only limited space can be measured. Therefore, we propose a mobile mapping system and automatic slant map generation algorithm, configured to capture urban environments online. Additionally, we use the LiDAR-inertial mapping algorithm to construct raw point clouds with gravity information. The proposed method extracts walls from raw point clouds and measures the slant angle of walls accurately. The generated slant angle map is evaluated in indoor and outdoor environments, and the accuracy is compared with real tiltmeter measurements.

Disasters are now becoming commonplace and especially the vulnerable group such as the disabled, the elderly, children and foreigners are in a state of overlapping disasters. In this situation, ATSC 3.0-based UHDTV disaster information service for the visually and hearing impaired has been developing. This study focuses on the demand data collected through in-depth interview with the impaired. The demand analysis data is very important to development process of technology. The results of the interview show that it is essential to link the UHDTV disaster signals with home-network, IoT, wearable devices, and various assistive devices for the impaired (hearing aid, smart light bulbs, warning light, etc.). In outdoor space, UHDTV disaster information must be connected to public display media, digital signage, kiosk, screens in bus or taxi. If communication aids for the visually and hearing impaired are equipped with a function that can transmit and receive disaster information, it will help to minimize disaster damage.

This study aimed to analyze health promotion villages from the perspective of therapeutic architecture, and to provide basic information for planning relevant health facilities. On the basis of a review of previous literature, the characteristics of therapeutic architecture were classified into eight categories: safety, comfort, sociality, autonomy, openness, diversity, privacy, and natural environment. Field study and observation were performed in four health promotion villages that conduct programs for lifestyle improvement, physical fitness, and treatment; these villages were also considered to have a healthy residential environment. The researcher and three assistants visited the facilities and checked utilization of space through interviews with the staff and guided tours. Basic information about the subject facilities, such as the purpose of establishment, was gathered from websites before visits. Two of the villages examined in this study had a traditional Korean wooden structure, while the other two were reinforced concrete and masonry block structures. All the facilities emphasized the use of environmentally friendly material and harmony with nature. Each site was divided into the following areas: office, residence, health/treatment, public/rest, and outdoor. The safety standards of the healing architecture were not completely satisfactory at all facilities. In particular, it was found that they lacked adequate universal design equipment. However, the healing characteristics of autonomy and diversity were strong. With regard to autonomy, the facilities allowed visitors to select indoor-outdoor moving lines and the use of front- and backyards constructed on slopes. In addition, they were equipped with many entries, staircases, void, terraces, and crossroads. The architecture was aesthetically designed using feng shui symbolism, and visitors found the scenes depicted in various spaces in the villages to be stimulating. Besides, the facilities were constructed using natural materials, had a natural indoor environment, and provided a sense of spaciousness and flexibility.

Nowadays, public rental apartments' community facilities emphasize only their quantity aspect without considering residents' characteristics, leading their installation regulations to be based on only the number of households, which is problematic. As a result, in many cases, residents, after moving in, alter the facility usage or remodel the facilities for their use. Hereby, this study conducted focus group interviews with public rental apartments' residents as to find out space conditions of and improvement demands for the community facilities. Two public rental apartment complexes in Seoul and Gyeongi-do which were built after 2007 were selected for this study. As for the survey method, workshop panel was employed. Four people in each age class of infants, children, adolescents, adults, and seniors were formed into one group, and a total of 40 people in 10 groups were surveyed. The survey was continuously conducted from February to March in 2009. The study findings can be summarized as follows. 1) Among community facilities, there were more satisfactory outdoor facilities than satisfactory indoor facilities. Residents expressed satisfaction with the facilities linked with natural environment. The causes of unsatisfactory facilities were mostly poor management. 2) The facilities demanded by the residents included ones relevant to study, exercise, and hobbies. As public rental apartments are resided mostly by low-income families, study and hobby activities bring them cost problems. Therefore, it is needed that the apartment complexes support diverse such activities 3) As for facilities demanded for usage alteration, a residents' meeting room accounted for the most popular opinions. As it was used only once a week, its usage was very low. It should be opened to the residents and allowed to be used in various ways. 4) As for demands of changing spatial characteristics, outdoor exercise facilities accounted for the most opinions. Although they were installed in most cases, they were damaged and poorly managed, therefore being in need of improvement in operation and management. In order to maximally utilize public rental apartments' community facilities, facility planning in consideration of various age groups from residents' viewpoint and sustainable systematic management are required.

Objectives: Respiratory virus infections are the most common disease among all ages in all parts of the world and occur through airborne transmission. The purpose of this study was to detect and quantitate human respiratory viruses in residential environments. Methods: Air samples were collected from the residential space of apartments in the Seoul/Gyeonggi-do area. The samples were collected from indoor and outdoor air. Among respiratory viruses, influenza A virus, influenza B virus, parainfluenza virus, metapneumovirus, respiratory syncytial virus, and adenovirus were investigated by multiplex polymerase chain reaction. Among the virus-positive samples, we performed adenovirus quantification by real-time polymerase chain reaction. Results: Virus detection rates were 44.0%, 3.8%, 3.4%, and 17.3% in spring, summer, autumn, and winter, respectively. The virus detection rate was higher in winter and spring than in summer and autumn. Adenovirus was most commonly detected, followed by influenza A virus and parainfluenza virus. Virus distribution was not significantly different between indoor and outdoor environments. Conclusions: Although virus concentrations were not high in residential environments, residents in houses with detected viruses may have an increased risk of exposure to airborne respiratory viruses, especially in winter and spring.

The purpose of this study is to the examine sense of community of the residents living in an apartment complex and the relevant features of the community facilities provided in the complex, such as actual facility conditions, needs and satisfaction. Five apartment complexes constructed after 2000, each containing more than 500 units were selected for this case study. The actual conditions of the community facilities regulated by current laws were inspected. Those facilities were the administration office, gym, multi-purpose room, sauna and shower room, indoor and outdoor children's play-grounds, study room, etc. 37 residents were interviewed to access their needs and level of and satisfaction with the provided community facilities. Based on the results, we suggest that basic community facilities for exercise, child care and children's recresion need to be provided regardless of the apartment complex size. The respondents revealed a medium level of sense of community, which was psychologically limited to their apartment complex. Indoor and outdoor children's play-grounds had great potential to encourage social interaction between the residents. The findings point to a need for improvement of the current relevant regulations with the perspectives of flexibility and application in terms of space size and mandatory types.

In this paper, With the development of modern science and technology are Sheds to stay indoors rather than outdoors space it increased significantly compared to the past. And a wide variety of research about outdoor air quality until recently, efforts are underway but the issue of air quality in the room is the fact that all considered relatively lightly. As the contamination of the room air is polluted, unlike the natural environment, a large outdoor air dilution rate, the dilution rate is very low, once the contaminated air continuously circulating exerts a very bad influence on the health of people staying in the room. In this study, movement characteristics of the person living in a room, the air measuring device for the study of the active indoor environmental control system reflects the life form to measure the quality of the measured air in real time for transmitting the information to the user of the smart devices, alarm bot It was implemented and operational applications.
