Recently, the number of traffic accidents on trunk roads tends to decrease due to the performance improvement of passenger vehicles. In the commuter rush hour of morning and evening, vehicles via residential road increases without going along trunk roads. Therefore, there are many traffic accidents of pedestrians (or bicycles) and vehicles on residential roads. In order to safeguard residents against traffic accidents, traffic calming devices (TCD), such as chicane, speed hump, and school zone, etc. have been introduced. Investigating these effects repeatedly is not easy since many times and efforts are required, such as observed at the place actually. In this paper, the effects of TCDs in residential areas, such as noise, speed, and emission of a vehicle, using Simulation of Urban Mobility (SUMO) are examined. As a result, it is found that it is possible to reduce the speed of the vehicle by TCD, and the level of noise at the location behind TCD becomes higher than the level of noise at the location of TCD implemented.

As environmental pollution has become worse green technologies to replace or reduce consumption of fossil fuel get spotlight from government, industry and academia globally. It is reported that 40% of carbon dioxide emission is caused by electricity power generation. And 37% of end user electricity power is used by residential costumer in US. Smart Grid is considered as one of promising technology to alleviate severe environmental problem. In residential environment, Home Energy Management System (HEMS) can play a key role for green smart home. The HEMS can give several benefits like aslowering electric utility bill, improvement of efficiency of electric power consumption and integration of generator using renewable energy resources. However just limited functions of HEMS can be used for residential customer in real life because of lack of smart function in home appliances and optimal managing software for HEMS. This study provides comprehensive analysis for Home Energy Management System for residential customer. Simple HEMS system with real products on the market are explained and limitation of current HEMS are also discussed.

The fire in Ulsan in 2020 was a 33-story residential and commercial complex with about 90 injuries and more than 10 billion won in property damage, and considering the recent increase in high-rise residential and commercial complexes, the risk of similar fires is high. As can be seen through the residential and commercial complex fire case in Ulsan, life-based fire safety standards need to be established to minimize casualties. Therefore, the purpose of this study is to draw improvements for the development of human safety standards for high-rise residential facilities in the future through comparison with the Korean Building Act, Firefighting-rellated Acts and the U.S. NFPA 101.

The purpose of this study is to estimate the perception of elderly residents on the residential environment improving projects and suggest the political implications. The survey include questionnaires about the importance and the satisfaction level on the project maintenance factors. The results were statistically analyzed by Importance-Performance Analysis (IPA). As the result of the study, firstly, it shows that 'the possible overkill area' on the IPA action grid includes none of factors except 'landscape' which is very similar to mean of performance score. the result of analysis means that the project is very efficient. Secondly, the policy is necessary to improve 'pedestrian passage', 'public open space' and 'transportation environment'. Considering elderly residents especially 'pedestrian passage' and 'public open space' are in need of improvement immediately. In detail 'traffic facility', building 'urban park' and 'pedestrian passage', 'paving of pedestrian passage', 'children's playground' are in need of improvement as well. The results of analysis on elderly and non-elderly residents of Yonnam project may be important foundation for future strategies for improvement.

This study aims to find out the cause of delay by analyzing the process of 12 Core-based Improvement pilot projects, especially focused on lands, buildings, population status. For this purpose, it performed a literature research on maintenance plan reports, various statistics of building and population status analysis, a field research and an individual interview with public officials in charge at local governments of 12 project districts. The findings are as follows; 1) it was difficult to cope flexibly to environmental changes because the core sector was so large that the plan was led to areal improvement. 2) the project was selected without reflecting the characteristics of the core sector and the area of residents-led renovation properly in terms of building status such as building density and old buildings ratio, 3) the coordinator group for socially disadvantaged class in the district was not operated and thus foundation for residents-led renovation was not set up. In conclusion, it should be presented the proper size of the core sector when the core-based residential environment improvement project is initiated in the future. In addition, building status is taken into consideration when designating the core sector and the area of residents-led renovation. The coordinator group needs to be operated from the early stage of the project as well.

Townhouse have been developed as alternative housing types for combining the characteristics of detached houses and high-rise apartments, Much research on townhouse have investigated physical environments of townhouse and provide a number of planning factors to be considered. However, these factors do not reflect the residents' experiences of the environments sufficiently. The aim of this research is to investigate residents' satisfactions in townhouse as an exploratory study which can be a basis for the improvement of residential environments in townhouse. First of all, we selected a target townhouse and conducted a field study to examine the existing state of the townhouse. Then a customized questionnaire was developed and distributed to residents in the townhouse for investigating their satisfactions on the residential environment. The questions included are divided into four categories; site environment, unit space, community area and housing management. Through the statistic analyses of the residents' responses, the residents' satisfactions of the residential environment were identified. Especially the residents' satisfaction on the community area, which revitalizes neighborhood relationships, is very high. They were also satisfied with the conditions of the sub-categories, 'a distinctive exterior' 'a private planning', 'outdoors' and 'landscapes', in townhouse. In conclusion, we suggested considerations for the improvement of the residential environments and the quality of life in townhouse.

The purpose of this study is to examine the residential institutions for the disabled in Korea on the base of welfare rights, and to propose some actual ways for improvement. For this, we analyzed the attributes of the residential institutions for the disabled in Korea. The results shows that the residential institutions for the disabled in Korea are characterized by massiveness, isolation, inequality in power, and no choice. For improvement we suggested that the residential institutions for the disabled should be run by the principles of supplement, normalization, inter-reliance, and individualization. In order to achieve these goals, the government has to invest the needs for de-institutionalization of the users, run the institutions on the smaller scale and replace them in communities, and systemize the person-centered support and service provision processes. In addition to them, the managers of the institutions should try to socialize the institutions, and to increase the participation of the users in management.

This study aims to derive street design alternative which can be applied to residential area as the functions of land use have been changed. The main findings are as follows; First, the study area in this research is on the process of the functional transition from full residential use to residential-commercial mixed use with cafes and restaurants. Second, dead-end streets in residential areas needs to be widened in order to meet the increasing needs of pedestrians and cars. One of the suggested strategies is to remove fences on the dead-end streets. Third, based on the main findings, this research can suggest following policies. Citizen participation is necessary in building land use plans and space design in old residential areas. Citizens can participate in architectural and landscape contracts, district-unit plan with the help of experts such as urban planners and architects.
