  • This study investigated exposure to air pollutants in rooms in low-income houses at Shomolu (R1), Mafoluku (R2) and Mushin (R3) in Lagos state. The concentrations of most measured exceeded limits of Illinois Department of Public Health (IDPH) for indoor air quality. Air quality index (AQI) in rooms studied was unhealthy for sensitive people in terms of CO, unhealthy in terms of $SO_2$ and very unhealthy in terms of $NO_2$ while moderate air quality was obtained in terms of $PM_{10}$ in most rooms. High concentrations of carbontetrachloride, formaldehyde and xylene measured could have been responsible for some of the health complaints of the occupants. Factor analysis shows that cooking with kerosene, use of gasoline generator and insecticide were the major contributors to indoor air pollution in these rooms. Therefore, there is need to urgently tackle poverty as all affected by these pollutants were poor who live in substandard houses without kitchens.

  • In this study there was the analysis of government incentives and resident support of public crematoriums, typically identified in Korea as a locally unwanted land use (LULUs), in the metropolitan area. The study looked at what government programs would be potential incentives for allowing the crematoriums to exist in metropolitan communities. Such programs were diverse, with projects focused on: enhancing resident welfare, increasing resident income, funeral facilities and management consignment, community oriented programs, education, funding, and others. Among them, it was found that residents were most in support of programs for enhancing resident welfare and increasing income among residents. In order to resolve the complexities of community support for LULUs and government incentives to shift public perception of cremation, three main policies are proposed. First, it would be necessary to compliment additional project support policies which provide medical services, resident prefered projects, and improvement of substandard housing. Second, it would be important to establish ordinances concretely identifying residential support projects based on community needs assessment. Lastly, it would be of the government's best interest to build policies for resident supported projects that reflect local conditions and the residents' demands for allowing non-preferred facilities to be built, and then to analyze the economic feasibility of these demands.

  • In the present research work, the effectiveness and the efficiency of a retrofitting approach using a layer of ultra-high performance fiber reinforced concrete (UHPFRC) jacket for damaged substandard exterior beam-column joints (BCJs) is experimentally investigated. The main objective of this study is to rehabilitate the already damaged BCJs to meet the serviceability requirements without compromising safety. According to the proposed strengthening technique, a chipped surface, lightly brushed with a dry condition was selected for making a successful bond between normal concrete substrate surface (NCSS) and UHPFRC. Then a fresh UHPFRC jacket with a thickness of 30 mm was cast around the damaged specimens. The entire test matrix was comprised of three 1/3 scale damaged exterior BCJs with a different column axial load (CAL). These specimens were repaired with UHPFRC and retested under monotonic loading. Based on the experimental results, repaired specimens showed an excellent performance in terms of their load-displacement response, maximum strength, displacement ductility, initial stiffness, secant stiffness and energy dissipation capacity when compared with the corresponding values registered when these specimens were tested in their virgin state. This rehabilitative intervention not only restored the strength, stiffness, ductility and energy dissipation capacity of severely damaged specimens but also improved their performance.

  • As people get aged, we need to pay more attention to the elderly living condition with respect to welfare policy. The present study focuses on housing condition of elderly people living in rural area, and analyzes its determinants, periodical difference, and regional disparities, incorporating an index of minimum housing standard. This study applies multi-level logit model that has a strong statistical advantage that can take random aspects of household and regional context into account. We found that married couple household, presence of economically-active family members, higher education, specialized profession, migration and higher level of land price tend to lower the probability of residing in substandard housings. We also found that housing conditions for elderly people prove to be different by regions and it is particularly noticeable in mountainous rural areas in Gyeongsangnam-do and Gyeongsangbuk-do with the poorest elderly housing conditions. Results also implies that housing welfare policies should be implemented differently considering the target groups based on regional differences. We conclude with some additional policy implications for the elderly living in rural areas.

  • 최근 도심지는 급격한 인구집중과 교통량의 증가로 인하여 맨홀사고 발생이 빈번히 발생하고 있다. 그러나 현재 우리가 사용하고 있는 맨홀들은 신도시를 제외한 대부분의 도심지에서 시설용량 부족 및 침하, 균열, 단차 등 노후화로 인하여 유지관리에 상당한 어려움을 겪고 있으며 경제적 여건과 사회적 인식의 부족으로 관리의 어려움이 있는 실정이다. 그래서 가능한 범위에서 할 수 있는 최선의 방법으로 맨홀시설의 기준을 보다 효과적으로 수립하여 내구수명 연장을 통한 도시화, 인구집중화에 대응할 필요가 있다. 본 연구에서는 현재의 우리나라 맨홀의 설치기준과 외국의 설치기준을 비교하여 상이한 점을 찾아보고 그에 따른 효율적인 기준이 무엇인지 연구한다. 또한 도심지 맨홀의 조사를 실시한 자료를 바탕으로 상관성분석을 통하여 기존 하수도 시설기준을 보다 체계적이고 세부적으로 보완하고자 한다. 본 연구의 성과는 맨홀의 유지관리상 문제점을 파악하고 보다 안전하고 효율적인 맨홀 설치의 기준을 제시하고자 한다.

  • The purpose of this study was to examine the selection process of the marathon course and the progress of the related urban landscape design projects. The study revealed that the initially selected course of the downtown Namdaemum changed to the riverside course that runs around Gangnam and Han river. This change implied that showing the developed landscape of Seoul was much more considered than showing the traditional landscape of Seoul. The urban design plan had changed in 1986 after the marathon course was finalized. The development project of downtown was changed to Gangnam area including Teheran-ro. The city also redeveloped the substandard housing zones around the Olympic facilities. As a result, developed areas and modern apartments of the riverside was emphasized in international TV game broadcast. This embedded the industrialized and modernized image of Seoul to foreigners. Also, Koreans started to recognize the Han river as Seoul's representative landmark. Accordingly, Seoul succeeded in creating a modernized urban landscape image through the Olympic marathon course.

  • While the lateral confinement provided by an FRP jacket to a concrete column is passive in nature, confinement is activated when the concrete expands due to additional compression stresses or significant shear deformations. This characteristic of FRP jacketing theoretically leads to similar initial stiffness properties of FRP retrofitted buildings as the buildings without retrofit. In the current study, to validate this theoretical assumption, the initial stiffness characteristics, and thus, the potential seismic demands were investigated through forced vibration tests on two identical full-scale substandard reinforced concrete buildings with or without FRP retrofit. Power spectral density functions obtained using the acceleration response data captured through forced vibration tests were used to estimate the modal characteristics of these buildings. The test results clearly showed that the natural frequencies and the mode shapes of the buildings are quite similar. Since the seismic demand is controlled by the fundamental vibration modes, it is confirmed using vibration-based full-scale tests that the seismic demands of RC buildings remain unchanged after CFRP jacketing of columns. Furthermore, the damping characteristics were also found similar for both structures.

  • Purpose: The purpose of this study is to present policy implications by analyzing the residential environment in North Korea under the Kim Jong-un regime. Research design, data, and methodology: Residential environment analysis was reviewed by dividing it into physical, socio-cultural, economic, environmental, and policy aspects. Results: Pyongyang are considerably superior due to it being the residence of the country's leadership and middle class. Secondly, there is a concerning problem with the provision of substandard housing. Construction materials are in short supply, and unreasonable timelines often lead to uninhabitable houses, signaling a need for assistance in housing construction. Thirdly, there is a severe lack of essential residential infrastructure, such as reliable electricity and clean water supply, which significantly impacts the quality of life. Lastly, due to the country's economic hardships, basic housing rights are not guaranteed, leading to deplorable living conditions for many North Koreans. The report suggests that these issues should be addressed through international aid to guarantee the basic human rights of North Koreans. Conclusions: In North Korea, the poor living environment deteriorates the health and quality of life of citizens and adversely affects social and economic development. Therefore, international support and cooperation to improve the living environment of North Koreans is important.
