The domestic housing paradigm has changed from quantitative growth to qualitative growth, and demands for pleasant living environment and meeting basic living conditions have increased due to increased living standards of the people. In a related move, the Ministry of land, Infrastructure and Transport introduced "long-life housing construction standards" in the Article 21 paragraph 6 of the Housing Act through a revision of the Housing Act in December 2014, devised detailed criteria and enforced the Ministry of Land, Infrastructure and Transport, titled "long-life housing construction certification standards" which require long-life housing certification in construction of apartment houses that accommodate more than 1,000 households. In this regard, A survey of consumers was conducted to collect opinions about consumers' perception and requirements regarding long-life housing, and thus to promote long-life housing and improve certification system criteria. The general public who wish to purchase housing were selected as the subjects for the present study, and the survey was conducted at the site of apartment house PR hall in Seoul and Gyeonggi-do as of January 2015. The result of this study is an opinion survey of long-life housing consumers. For future work, additional research is needed to establish legal standards and devise support systems, along with technology development for long-life housing.

In line with the recent public concern on the environmental issues in building industry, there has been a rise in demand for a healthy, sustainable housing environment in South Korea. In order to achieve a healthy environment in residential buildings, considerable efforts have been made in a wide range of sectors. Among others, the development of the certification schemes to promote environment-friendly planning and building construction is remarkable. In urban South Korea, recently built houses tend to be significantly high-rise, high-density buildings. Global warming has brought about drastic climate change and continued to increase the average annual temperature year by year. These changes should be well reflected on the government's implementation of the building environmental assessment system. For guidance, therefore, this study looks to the case of Hong Kong which is well known for high-density housing development and subtropical climate conditions. It compares the features of the green building certification schemes for newly developed multifamily housing in two regions, namely HK-BEAM in Hong Kong and G-SEED in South Korea. Based on the findings, it argues that the G-SEED implementor should have expanded roles in providing training programs and follow-up services in collaboration with the certification authorities. It is also argued that G-SEED professionals should be involved in the early stages of design processes, and training programs and licence systems to produce green building professionals should be developed. Finally, it points out that the assessment indicators should be more detailed and diversified.

This study explored the characteristics, housing deficits and expectations for support programs of low-income renter households in housing poverty in order to provide housing policy development and improvement information. Microdata of the 2014 Korea Housing Survey was utilized as secondary data for this study. A total of 2,508,672 low-income renter households (weighted count) in the bottom 40% income ranks of entire general households living in private rental units were selected as study subjects. The major findings were as follows. (1) One point four percent of the subjects were living in non-house living quarters (e.g., shanties, vinyl greenhouses, container houses, and mud huts), 1.4% were in dosshouses, 9.9% were in basements, semi-basements or rooftop units, and 8.2% were in sub-standard units. (2) Among the households whose housing costs burdens were measurable, 75.7% were found to have housing cost burdens to pay 30% or more of their household income towards housing costs (rental costs and maintenance costs), but only 7.5% of the burdened households received a housing voucher. (3) Eighty-one percent were found to be in a housing poverty status as defined by the researcher; in addition, low-income renter households in housing poverty in Seoul tended to have a greater proportion of households headed by females, the elderly, and be persons with low-education or disabilities. (4) Households in housing poverty showed greater expectations for financial support and/or extended provisions of public rental housing than other low-income renter households.

Ikseon-Dong 166 is one of the traditional urban resident area developed during 1930's. The purpose of this research is to analyze the structural relationship between a conventional housing unit plans and modern block plans based on orthogonal geometry. To fully explore the selling point of the new urban development, the planner or real estate developer in private sector did not abandon or compromise the conventional house layouts, consists of single layer of rooms keeping the main room facing south. This study concludes the following factors connecting the urban and architectural plans. Oblong block plans following east-west direction did not allow the southern exposure of courtyard and main room, which was the absolute requirement for traditional house units, the longer side of block plan followed north-south direction as a result. Considering the possibility of rent, having entrance at the east or west side of individual site enables two separate household maintain their spatial privacy. In addition to the factors mentioned above, when the blocks are to be divided into individual addresses, north-south oblong block plans maintained the length to face the front road minimum while the southern exposure maximized. These factors explains why the private developers maintained their blocks elongated to north-south direction when the block plans laied out by public sectors which did not care that much of southern exposure show random orientation in the view point of solar exposure.

Recently, some researches related to air pollution problems in large cities of the Islamic Republic of Iran have been done. Famous institutes and research centers in countries like Japan, Sweden and Germany have been in cooperation with Iranian institutes in implementing the results. Due to quick increase in the population because of peoples＇ migration from countryside to cities, and rate of growth in the early years after the revolution, air pollution was an important problem in I.R.Iran. Therefore, air pollution control is one of the main issues in major cities of I.R. Iran. It is the purpose of this study to investigate the control mechanisms for air pollution problems in the major industrial cities. The necessary action plans that were taken in recent years in some of the cities, which were also suggested to be taken in the other ones, are the other purpose of this study. From the results of studies it was obtained in Iran, lots of researches are important to mention. Amongst the main activities that are done in recent years are： establishing of the meteorological research centers and atmosphere sciences; three applicator meteorological research centers and more than 40 new stations in the country; installation of newest computer systems in metrological information, using of wall map and continuous radio-traffic to announce traffic news; completing of subway construction in Tehran; forbidding of industrial activities in a definite distance away from Tehran and transferring them to suitable places; building of highways and freeways; improving of public transportation and gasifying them; developing of fuels quality and removing lead from them; and gasifying of the heating systems in houses and buildings.

본 논문은 제2차 세계대전 이후 미국 캘리포니아에서 전개된 케이스 스터디 하우스(CSH) 프로그램을 대상으로 유럽에서 시작된 근대주택의 개념이 미국화되어 가는 과정을 파악하고 그 건축적 특징을 제시하고자 한다. CSH 프로그램은 미국식 근대주택의 개념이 설정되어 가는 과정에서 선도적인 기여를 한 것으로 이해되지만, 동시에 실행과정의 한계때문에 공공사업으로 확대되지 못하고 소규모의 실험적 프로젝트로 한정되었다. CSH프로그램의 실행단계에서 가장 큰 난제는 주택시장의 유통과정에서 효과적으로 대응하지 못하고 가격경쟁력을 잃어버린 점이다. 하지만, 유럽의 근대건축을 수용하고 발전시켜 미국식 실용주의에 근거한 독자적인 건축양식으로, 그리고 미국 근대건축의 원형(prototype)으로 이해될 수 있도록 했다는 측면에서 CSH 프로그램의 중요성은 높게 평가받아야 한다. CSH 주택들은 유럽 근대주의의 연장선상에서 실용주의를 기반으로 한 미국식 근대주택의 개념을 대변하는 위치에 있다.

This study is an attempt to quantify rainwater utilization and miscellaneous water demand in Tokyo's 23 special wards, the core of the urban area in Tokyo, Japan, in order to elucidate the potential of further rainwater utilization. The rainwater utilization for miscellaneous appropriate water demands, including toilet flushing, air conditioning, and garden irrigation, were calculated for six different types of building: residential house, office, department store, supermarket, restaurant, and accommodation. Miscellaneous water demands in these different types of building were expressed in terms of equivalent rainfall of 767, 1,133, 3,318, 1,887, 16,574, and 2,227 (mm/yr), respectively, compared with 1,528 mm of Tokyo's average annual precipitation. Building types, numbers and its height were considered in this study area using geographic information system data to quantify miscellaneous water demands and the amount of rainwater utilization in each ward. Area precipitation-demand ratio was used to measure rainwater utilization potential for miscellaneous water demands. Office and commercial areas, such as Chiyoda ward, showed rainwater utilization potentials of <0.3, which was relatively low compared to those wards where many residential houses are located. This is attributed to the relatively high miscellaneous water demand. In light of rainwater utilization based on building level, the introduction of rainwater storage mechanisms with a storage depth of 50 mm for six different types of buildings was considered, and calculated as rainfall of 573, 679, 819, 766, 930, and 787 (mm), respectively. Total rainwater utilization using such storage facilities in each building from 23 wards resulted in the retention of 102,760,000 $m^3$ of water for use in miscellaneous applications annually, and this volume corresponded to 26.3% of annual miscellaneous water demand.

The houses are formed in the lower part of the mountain slope face in most agricultural areas of Korea, and old residents accounting for a large portion of the agricultural populations cannot respond to the evacuation quickly when the landslide happens, and the possibility the life damage occurs is high. Therefore, it is urgent to arrange the measure on this. This study is intended to develop the personal disaster evacuation apparatus that can be installed in the house to minimize the life damage by the landslide and to develop the self-initiative evacuation apparatus. This study suggested the load applicable to the personal disaster evacuation apparatus by quantitatively analyzing the effect of the load of rockslides and avalanches caused by the landslide on the structure. Also, the material property of materials was calculated through the tension and bending intensity test after making the specimen of glass fiber reinforced plastic (GFRP) member. The load weight and material property drawn from this study can be used as the basic material for the stability analysis of the personal disaster evacuation apparatus.

Significant costs to the public and private sectors due to recent extreme wind events have motivated the need for systematic post-hurricane damage data collection and analysis. Current post disaster data are collected by many different interested groups such as government agencies, voluntary disaster relief agencies, representatives of media companies, academicians and companies in the private sector. Each group has an interest in a particular type of data. However, members of each group collect data using different techniques. This disparity in data is not conducive to quantifying damage data and, therefore, inhibits the statistical and spatial description of damage and comparisons of damage among different extreme wind events. The data collection does not allow comparisons of data or results of analyses within a group and also prohibits comparison of damage data and information among different groups. Typically, analyses of data from a given event lead to different conclusion depending upon the definition of damage used by individual investigators and the type of data collected making it difficult for members of groups to compare the results of their analyses with a common language and basis. A formal method of data collection and analysis-within any single group-would allow comparisons to be made among different individuals, hazardous events and eventually among different groups, thus facilitating the management and reduction of damage due to future disaster. This research introduces a definition of damage to single family dwellings, and a common method of data collection and analysis suited for groups interested in regional characterization of damage. The current state-of-data is presented and a method for data collection is recommended based on these existing data collection methods. A fixed-scale damage index is proposed to consider the damage to a dwelling's feature. Finally, the damage index is applied to three dwellings damaged by Hurricane Iniki (1992). The damage index reflects the reduced functionality of a structure as a single family detached dwelling and provides a means to evaluate regional damage due to a single event or to compare damage due to events of different severity. Evaluation of the damage index and the data available support recommendation for future data collection efforts.
