  • In this paper, we proposed a plan for a indoor air quality management in elderly care hospital by measuring the indoor air quality level of elderly care hospital and conducting a survey the workers' awareness of indoor air quality. The measurement items were Temperature, Humidity, CO2, CO, PM10, VOC and were taken on April 26, 2019. The survey found that the lower the satisfaction level with indoor air quality, the better outdoor air quality and odor items were analyzed to be the lowest among the indoor environmental factors. When the satisfaction level of indoor air quality is high, the satisfaction level of indoor environment factor is high. The result of the multiple response analysis was "lack of ventilation" and the regression analysis was the lower the "relevance of indoor air quality" category. To provide the best indoor air quality environment for elderly care hospital workers the installation of additional ventilation equipment to remove odors, the increase in the number of natural ventilation and the designation of regular ventilation personnel will be necessary. By establishing such a plan, it is possible to provide indoor air quality environment to provide the best services for elderly care hospital workers.

  • This paper discusses the importance of indoor air quality based on literaure review of domestic and foreign studies. A number of international efforts to propose standards and guidelines for indoor environmental quality are also reviewed. The pattern of major studies on indoor air quality focussed on characterizaton of gaseous pollutants, particulates, and other specific pollutants during the past decades, whereas VOCs, specific carcinogen, and microbiological agents might be good target pollutants to investigate the effects of human health in recent years. Management of indoor air quality requires a different approach than that adopted for outdoor air. Adequate ventilation of the indoor environment is essential, and a balance between energy conservation and the need for good air quality is required. The ways for managing indoor air quality that will be of great importance are discussed a role of control policy for guidance on how to achieve good indoor air quality.

  • The degree of air pollution is usually presented in terms of concentration. But, in evaluating the environmental impacts or air pollution control policies, the concentration values need to be interpreted in terms of damage effects on property and human health. The damage effect varies with the types of pollution, subjects and land use pattern of an affected area. Therefore, this study is aimed at developing a method of analyzing effects of various types of air pollutions on surrounding environmental setting with the EIMS (Environmental Information Management System) developed for land suitability analysis. Using the method formulated in this study, the long- term effects of such pollutants as $SO_2$ and HF on types of vegetation and residents, and potential, short-term effects of HCl leak accidents from manufacturing facilities in Ulsan and Onsan Industrial complex are analyzed. The presentation of the damage effects of air pollution rather than the concentration of pollutants will be useful for the preparation of environmental impact statements, the formulation of environmental policies, and the development of land use plans in heavily industrialized areas.

  • This study suggests plan of green space management based on the result of research apprehending the characteristic through sorting types of city thermal environment targeting summer which thermal pollution is the most serious. Considering anthropogenic heat, development level of wind road, thermal environment, as a result of types of thermal environment process, it is appeared 36 types, and 10 types is relevant of this research subject. Type I-1, size of building is large, artificial covering area is wide, and thermal load of anthropogenic heat is high, type II-1, development condition of wind road is incomplete as IIlevel, entering cold air is difficult and thermal management and improvement is needed area. Type III-1, scale is large and it is area of origin of cold air, development level of wind road is mostly favorable, type III-2 is revealed as smaller scale than III-1, and small area of origin of cold air. Type IV, anthropogenic heat is $81{\sim}150W/m^2$, average, but development function of wind road is very favorable. Type V, large area of thermal load and the origin of cold air are distributed as similar ratio, and level of development function of wind road is revealed as II level. According to standard of type classification of thermal environment, as a result of suggesting plan of green space management and biotops area ratio, type I-1 is buffer green space and waterway creation, goal biotops area ratio 35%, type II-1 afforestation in site and goal biotops area ratio 40%, type III-1, preservation plan to display the current function continuously is requested. Type IV suggests afforestation of stream current, and type V suggests quantitative increase of green space and goal biotops area ratio 45%.

  • Urban air mobility (UAM) is being considered as an alternative to transportation in urban areas where traffic congestion is increasing. It is judged that it will be difficult to manage the complex UAM operation environment with the existing Air Traffic Service, which is a person-centered service. Therefore, an advanced information processing-based traffic management system for UAM (UATM) is needed. Airspace management is essential to establish a systematic UAM traffic management (UATM) environment. In particular, the establishment of exclusive corridors where UAM aircraft can operate safely can provide opportunities to operate UAM aircraft without violating the minimum flight altitude regulations. This study conducted an empirical analysis using a helicopter of similar size to UAM to establish the cross-track dimension of the corridor for UAM operation. The research results can be used as a guideline when designing UAM corridors.

  • Indoor air quality is an important determinant of human health and comfort. However, the complexity of pollution sources and the multitude of parties responsible for creating indoor exposures makes the improvement of air quality difficult. The HVAC(Heating, Ventilating and Air-Conditioning) system is important facility to provide comfortable environment passenger service. The Ministry of Environment is established "Indoor Air Quality Management guidelines in Public Facilities"in December 2006. Hereupon, the train and the subway are included. In this research air quality in the Subway compartment has been measured. As a result, the concentrations of PM10 and $CO_2$ were reached to 93% and 61% of the regulation values, respectively. Thus, the indoor air qualities of subway have been proved that they satisfy the recommended guidelines by the Ministry of Environment.

  • Indoor air quality is an important determinant of human health and comfort. However, the complexity of pollution sources and the multitude of parties responsible for creating indoor exposures makes the improvement of air quality difficult. The KTX HVAC(Heating, Ventilating and Air-Conditioning) system is important facility to provide comfortable environment passenger service. The Ministry of Environment is planning to enforce$\square\square$Indoor Air Quality Management law in Public Facilities$\square\square$in year 2008. Hereupon, the train and the subway are included. In this research air quality in the KTX Train compartment has measured. As a result, The average amounts of PM10(particulate matters), $CO_2$(carbon dioxide)measured $20{\mu}g/m^3$, 1,097ppm in KTX respectively. There are compare to regulation the value is 10% for PM10 and 43% for $CO_2$. Thus, the indoor air quality of KTX train have been proved satisfy the recommendation the Ministry of Environment guidelines.
