This study aims to evaluate the residential exterior environment and ascertain the factors having an effect on the visual environment viewed through the living room window. This study is based on a questionnaire on the exterior environment targeting residents living in the area of Nohyunng in Jeju city, Jeju-do. The results are as follows. First, residents are satisfied with the exterior environment as a whole; however, the longer-term residents' level of satisfaction is found to be relatively low while dissatisfaction is high. Additionally, there is a difference in satisfaction and dissatisfaction levels between the residents in their own housing and those in rental housing. The residents living in rental housing were found to have a relatively low level of satisfaction and high dissatisfaction. Second, in the case where the living room window faces roads, low satisfaction and high dissatisfaction levels with the visual environment were found, where the living room is on the first or second floor. Third, satisfaction and dissatisfaction with the exterior environment have a close correlation to the impression or nature elements of 26 questions but they show low correlation in size, height, color, design, traffic, artifact elements. Finally, as a result of extracting the factors influencing satisfaction and dissatisfaction with the visual environment, four factors were extracted including "Impression & Nature factor", "Building factor", "Design factor", and "Traffic volume & Artifacts factor". "Impression & Nature factors" is the most influencing factor with satisfaction and dissatisfaction and "Traffic volume & Artifacts factor" was found to have an effect on satisfaction, but not as clearly on dissatisfaction.

The government has switched the purpose of housing policy, from the 'housing supply' to 'housing welfare', with the Housing Laws established in 2015 under evaluation that resident stability and resident standard were improved. But, as 'affordable' housing is gradually decreasing, residential environment has become more poor. Residential environment is a basic element for the child safety, health, and better education. This study explored that the poor resident environment had effect on the child, figured out the situation on housing poverty of domestic child and searched the situation of the residential policy of domestic and foreign child. The main results are as follows. First, the poor resident environment of childhood has a bad effect on the physical health, mental health, academic achievement and cognitive development. Second, 1.29 million children (11.9%) are living in condition of housing poverty below minimum resident standard and are concentrated in certain areas. Third, the policy on housing poverty of domestic child is almost absent and focuses on the elderly, young people. this study discussed political and practical solutions based on these research results. On the basis of these research results, as policy suggestions we proposed housing policy making based on the UN Convention on the Rights of the Child, evidence-based housing policy enforcement and, residential policy suggestions under the responsibility of central government, and as practical suggestions community working as the subject and related agency's solidarity from prevention activity of housing poverty and child advocacy point and we discussed way for issue and analyzed related laws, policies, commitments.

This paper reports the results of a field evaluation which used sampling and analytical methods to determine the levels of airborne hexavalent chromium Cr(VI) in major industrial complexes in Korea over a seven year period (2007-2013). Cr(VI) concentrations were determined using cellulose filter sampling and ion chromatography analysis. In order to validate the analytical performance of these methods, studies were also carried out to investigate data quality control (QC) parameters, such as the method detection limit (MDL), repeatability, and recovery efficiencies. The average concentrations of Cr(VI) for the nine industrial complexes in Korea were in the range of 0.09 to $1.40ng/m^3$, which is similar to of the concentrations in other industrial areas around the world. The impacts of Cr(VI) emissions from industrial areas on Cr(VI) concentrations in neighboring-residential areas were considerably low, and the dispersion of Cr(VI) from industrial areas to residential areas was estimated to be 'not-significant'. Cr(VI) levels were not affected by seasonal variation, which suggests that chromium was emitted continuously from the industrial sources throughout the year. The concentration of Cr(VI) measured accounted for 0.7 to 9.4 percent of the total chromium level, which is a low percentage compared to those in other urban areas around the world. This is the first report in an international journal of a field study conducted in Korea to determine the concentration of Cr(VI) in the ambient air of industrial and residential areas.

This research analyzes the residents' satisfaction for the pedestrian space of multi-family housing based on quality index. For this purpose, nine apartment complexes which were built after 2000, are selected and examined by user characteristics of composition factors of pedestrian space. This research also compares residents' satisfaction by evaluation factors of walking environment. The resident survey reveals that the composit type of apartment gives the highest satisfaction to residents followed by a courtyard type, and a straight type the last. In particular, residents show high satisfaction to pedestrian-only space in the case of the composit type of apartment building. The most important factor of walking environment on residential satisfaction is the separation of car and pedestrian path of main entrance. Above all, suitability of construction laws and regulations should be reviewed for safer and more amenable walking environment.

Noise and vibration occurs during construction intermittently, but with the most arise complaints. There is a need to efficiently manage the construction noise and vibration problems because in case a residential facility that requires calmness around the construction site adversely affects the living conditions of nearby residents. The ministry of environment has mandating the installation of soundproofing facilities for the management of construction noise. In order to enforce a particular construction, the mandatory install with soundproofing facilities before the start of construction, and after construction. However, Installation guide of soundproofing facilities for construction sites were not considered affected areas by noise and there is no provision of performance evaluation for soundproofing facilities. In this study, investigated the status and problems of the installation guide for soundproofing facilities in construction sites, we propose an efficient installation guide of soundproofing facilities for the reduction construction noise.

This study performed a subjective evaluation of the Semantic Differential (SD) method for living room activities to evaluate the living room lighting environment and investigated the relationship between these through luminance distribution in the space. As a result, three factors-"lightness", "emotion" and "calmness"-have been grouped together. According to the analysis of experimental variables, difference has been observed depending on color temperature, the dimming of the ceiling & cove lights and the use of down lights and a bracket. 'Conversation with Family', 'Having Fun with Family', 'Entertaining Guests' and 'Reading a Book or Newspaper' requires "lightness". In terms of "emotion"-centered activities, 'Watching TV' is the highest, but all three factors are related. In terms of "calmness"-centered activities, 'Relaxing' is the highest.

This research aimed to grasp the recognition of the amenity of the university students residing in Gyo-dong residential area in Gangneung city, the local residents residing in Daehag-ro which is near Jungang-ro in downtown and the public servants related to city development in Gangneung city office and thereby propose a plan to improve the amenity of Gangneung city. Based on the result of the research, the university student group around Gyo-dong residential area mostly recognized the amenity and the local residents around Daehag-ro showed insufficient recognition of the amenity and some of related public servants were found to be ignorant of the term amenity. Also, the priorities of amenity indexes identified from these 3 groups commonly showed aliveness requiring green lands and watercourses on top but 2nd priority of each group tended to be different from each other. Through the research result as above, we would like to propose the plan to improve as follows. First, the recognition of the concept of amenity is necessary. Second, green lands and watercourses that were selected by all of the 3 groups as ranking no. 1 should be secured. Third, the value of amenity resources should be evaluated. Gangneung city is a city where mountains and the sea are harmonized together granting abundant god blessed natural resources. But if Gangneung city would imprudently reclaims the excellent god blessed natural environment under the good title of city and housing lands development, its ranking in city competitiveness evaluations will be expected to continue descending. Therefore, as proposed in this research, the thing that has to be implemented with first priority for amenity Gangneung city is the execution of amenity policy to secure the identity of Gangneung city and the aspect of regulations or systems should also be pursued together with the policy.

Some arguments have been about over the representativeness of government-run air quality monitoring stations among scholars and non-governmental organizations (NGOs). However, it is not a simple problem to move monitoring stations because of continuity of data and high cost. So it is necessary to complement the monitoring data if it do not represent the ambient air quality properly. The purpose of this study was to evaluate the representativeness of some monitoring stations using passive $NO_2$ samplers and to find a complementary method from linear regression. Two stations were chosen for the evaluation: Shinlim Station was one of the most controversial stations in Seoul and Banpo Station had the best reputation. Air qualities were surveyed at seven points around each monitoring station with consideration of land use and distance. The ratios of the average $NO_2$ levels of the areas to these at the monitoring stations were 1.59 for Shinlim Station and 1.03 for Banpo Station. The differences between the average $NO_2$ levels and those at the monitoring stations were 10.75 ppb for Shilim Station and 0.34 ppb for Banpo Station. The correlation coefficients between the two levels were 0.7668 for Shinlim and 0.7662 for Banpo. The average coefficients of determination $(R^2)$ were 0.61 for Shinlim and 0.61 for Banpo. The Shinlim Station could not represent the air quality of Shinlim-Dong good because it is located in a green area at an outskirt of Shinlim-Dong. But the Banpo Station located in a central residential area of Banpo-Dong showed a fair representativeness. However, air quality turned out to be different with land use such as residential area, green area or road: the air quality data from a monitoring station located at a certain land use should not be interpreted as representing the air quality at any sites around the station. Equations to predict the average $NO_2$ levels of each area from the data from the monitoring stations were presented based on linear regression.
