In this paper, we have examined Seo Yu-gu's concept of rural home landscaping by reviewing the contents in Wonrim·Ganso in Hyungbipochi. The origin of his concept of rural residential landscaping reflects the Joseon Fengshui perspective following Bokgeo Sayo. Keeping in mind the requirements for living environment based on the Joseon Fengshui perspective, Seo Yu-gu interpreted Jiangjiuyuanji and introduced the components of ideal living that he had obtained from it in ways applicable and suitable to rural homes in Joseon. Jiangjiuyuanji, which contains the natural elements such as mountains, water, fields, and trees, could have been well received by Joseon scholars. As Seo Yu-gu explained in Sangtaekji, it had all the components of Nakto. In sum, constructing the hedges with three layers to promote the safety of rural residents and protect the food sources, utilising water sources for rural homes in various ways, and creating a beautiful courtyard Seokgasan and ponds were Seo Yu-gu's ways of reproducing the requirements for Nakto described in Jiangjiuyuanji such as a safe living environment surrounded by mountains resembling a lotus flower castle, a plentiful water source, and a beautiful natural environment based on the principle of 'Bokgeo Sayo'. In other words, through the content of his writing Wonrim·Ganso, he was articulating his thoughts on how to realise the ideal living conditions described in Jiangjiuyuanji in ways applicable to rural homes in Joseon. In the extended context of Imwon gyeongje ji, such deliberation of Seo Yu-gu shows a glimpse of the goals and practices he pursued through it. The content of Wonrim·Ganso in Hyungbipochi truly manifests Seo Yu-gu's approach to and understanding of Chinese literature. Moreover, his suggestions for application in rural Joseon villages verify the orientation and practical goals of Imwon gyeongje ji as he stated in the preface that 'the book was written specially for Joseon'.

Estimating the sales price of a residential building development project is difficult because of it has many complex variables such as location, environment, and economic conditions. Many previous studies related to influence factors of the sales price is to identify by survey of experts and it is few studies by comparing with actual sales price. Accordingly, the purpose of this study is to identify the factors influenced on the projects by using correlation analysis from collected actual data in this study. For the purpose, first, the factors such as economy, location, housing, financial environmental factors were identified from previous studies. Second, data were collected on actual sale prices and selected factors. Finally, the actual sales price and factors were compared and analyzed by using correlation analysis. As a result, the R2 values of economy, location, housing and financial environmental factors were over 0.5 respectively. Therefore, it was confirmed that these factors were significantly correlated with actual sales price. The results of this study are expected to be utilized as basic data for research and development of a new sale prices prediction model.

This study examined the environment and landscape aspects of rural villages, which are based on agriculture, to regenerate a disappearing rural village. The lifestyle and living conditions in this area were examined and the field survey of this area was carried out. The main negative factors at the rural landscape and living environment, such as rural households garbage, compost piles, and farming wastes, were found. An improvement plan of the landscape in this area was then determined. The disposal conditions according to the garbage types were analyzed through a survey with the residents directly. Through this survey, the current negative factors in landscape were checked and various improvement methods were assessed. Based on this, an institutional framework about landscape improvement of a village was developed, and a fundamental resource that can improve the environment of rural communities by this system is suggested.

The purpose of this study is to conceptually define "spatial inclusivity" and empirically examine the impact of disability severity and spatial inclusivity on social participation among individuals experiencing physical discomfort. The social and spatial environment of the residential area is crucial for individuals with disabilities who face limited activity range and complex barriers due to physical constraints. In this study, spatial inclusivity from the perspective of people with disabilities is defined as establishment of equal relationships with non-disabled individuals within the local community, as well as the availability of basic facilities and services in a safe urban space that allows for access and utilization. This concept consists of three dimensions: individual networks, social environment, and physical environment. The physical environment encompasses safety levels, natural environment, living environment, public transportation conditions, medical services in residential areas. We used the 2019 Community Health Survey to examine the relationship between disability severity, spatial inclusivity, and social participation using a two level regression model. The findings are as follows: Firstly, personal relationships at the individual level and the physical environment at the local level have a positive impact on social participation. Secondly, when identifying dividing the physical environment into five sub-factors, no significant influence of individual factors is found. Thirdly, trustworthy and friendly social environment at the local level has a negative impact on social participation. These results provide empirical evidence that spatial inclusivity has an effect on the social participation of individuals with disabilities and suggest implications for urban planning to create and enhance conditions for the social participation of individuals with disabilities.
The collapse of the underground cavities and voids, which were made for developing mineral resources, can cause the subsidence of the ground surface in the residential areas. During the Japanese colonial era and the 1960's mining boom period, lots of mines had been developed indiscriminately in Korea. Due to complicated geological conditions and mining methods, many of dangerous underground mine cavities with steep slopes had been generated at the shallow surface. Due to such conditions, it is difficult to directly apply valid foreign reclamation practice for the cavities in Korea environments. It is necessary to develop the efficient ground stabilization technologies for the Korea underground mine conditions to solve abandoned mine reclamation properly. Therefore, MIRECO and Korea government have been carrying out practical researches and technical developments together with other academic researchers and reclamation business partners, and various practical solutions such as surveying and exploration methods, proper cavity filling materials and reinforcement methods have been developed with application in the mine field. In this article, up to date technologies and R&D trends in the field of mine subsidence prevention technology are broadly reviewed to establish the future direction of a research and development.
This study was conducted to evaluate the level of atmospheric heavy metals and the relationship of that concentration with weather conditions. This research monitored the concentration of Total Suspended Particulates (TSP) at every three hours by using High Volume Air Sampler from December 24th, of 1995 to Febuary 20th, 1996 in Kimhae area, which recently became a rapidly growing residential and industrial sitc. The items such as air-temperature, relative humidity, radition, wind speed, and wind direction were monitored by using Atmospheric Weather System at the same time. From the collected TSP, the concentration of heavy metals were analyzed by using the Atomic Absorption Spcetrophotometry. The mean concentration of TSP was 110.4 $\mu\textrm{g}$/$m^3$, and the mean concentration of lead (Pb), copper(Cu), chromium (Cr), manganese (Mn), cadmium (Cd), were 0.837 $\mu\textrm{g}$/$m^3$, 0486 $\mu\textrm{g}$/$m^3$, 0.264$\mu\textrm{g}$/$m^3$). The concentration of Pb and Mn was higher in the moring and that of Cu, Cr and Cd was higher in the afternoon and the evening. Regarding the relationship between the concentration of pollutants and weather condition, the-concentration TSP revealed positive correlation with temperature, humidity, wind speed, but negative correlation with tradition (p<0.01). The concentration of Mn revealed positive correlation with temperature and humidity, but negative correlation with wind speed (p<0.01). And the the concentration of pollutants and weather condition revealed higher correlation within the same time period. In summary, the paralleled mornitoring of air conditions and weather condition should be recommended to. get the correct informations concerning the pollution and to prevent the deterioration of air conditions.

The chemical and meteorological effects on the concentration variations of ozone ($O_3$) were evaluated based on the intensive air quality measurement (5 pollutants and aromatic volatile organic compounds (AVOCs)) in and out-side an urban valley during spring and summer of 2006. The 5 pollutants measured in the study area include $O_3$, $NO_2$, NO, $PM_{10}$, and CO; the AVOCs include benzene (BEN), toluene (TOL), ethylbenzene (EB), m,p-xylene (MPX), and o-xylene (OX). For the purpose of this study, study areas were classified into two categories: valley area (VA) with a semi-closed topography covering a number of industrial complex, public building, and mountains and non-valley area (NVA) surrounding the suburban and residential areas. In general, the mean concentration levels of most pollutants (except for $PM_{10}$) in the VA were higher than those in the NVA. It was found that the average $O_3$ increase in the VA during spring might result from the combined effects such as the photochemical production from diverse anthropogenic sources and the $O_3$ accumulation due to geographical features (e.g., the semi-closed topography) and wind conditions (e.g., a low wind speed). In addition, the nocturnal $O_3$ increase in the VA during spring was primarily caused by local wind conditions (e.g., mountain and valley winds) with the low wind speed (approximately $1{\sim}2\;m\;s^{-1}$). On the other hand, the $O_3$ difference between the two areas during summer might be because of the photo-chemical production with the $O_3$ precursors (especially the AVOCs) rather than the contribution of wind conditions.

Purpose: Numerous researches about healthcare buildings have been performed however, they were mainly focused on convenience or healing condition for medical treatments. The hospitals consume energy and generate $CO_2$ as twice as the residential or commercial buildings do(Lim, et al., 2010a:154). The public regional hospitals are especially in serious conditions. They are more than 20 years old in average. Energy efficiency and environmental friendliness in the public regional hospitals are far behind ones in private sectors. Even though the ministry of health & welfare is supporting renovation of the builidngs and enhancement of the facilities every year, it is not integrated including sustainibility. In this study, we investigates current conditions of the regional public hospital in envrionment-friendly standpoint, especially focused on Chungcheong Province area Hospitals. Methods: we investigates current conditions of the regional public hospital in envrionment-friendly standpoint, especially focused on Chungcheong Province area Hospitals. The study was executed by qualitative and quantitative evaluations with site inspection, drawing analysis and interviews. Results: Through this study, we found that the Chungnam regional public hospitals can be environmentally improved by management plans and programs. Implications: Based on this analysis, Korean Green Building Certification for healthcare facilities will be developed in near future.

In this study, performance of 2 pure hydrocarbons R290 and R1270 was measured in an attempt to substitute R22 under 3 different temperature conditions. They were tested in a refrigerating bench tester with a hermetic rotary compressor. The test bench provided about 3.5 kW capacity and water and water/glycol mixture were employed as the secondary heat transfer fluids. All tests were conducted under the same external conditions resulting in the average saturation temperatures of $7/45^{\circ}C$ and $-7/41^{\circ}C$ and $-21/28^{\circ}C$ in the evaporator and condenser, respectively. Test results show that the coefficient of performance (COP) of these refrigerants is up to 11.54% higher than that of R22 in all temperature conditions. Compressor discharge temperatures were reduced by $14{\sim}31^{\circ}C$ with these fluids. There was no problem with mineral oil since the mixtures were mainly composed of hydrocarbons. The amount of charge was reduced up to 58% as compared to R22. Overall, these fluids provide good performance with reasonable energy savings without any environmental problem and thus can be used as long term alternatives for residential air-conditioning and heat pumping application.
