The purpose of this paper is to estimate the effect of population change on waste emission in the case of Busan City. The results are as follows : First, population and waste emission in Busan City Show decreasing pattern since 1995. According to increase or decrease of population and waste emission, The 16 Gus in Busan City are categorited into 5 types. Comparing the difference of population and waste emission between 1995 and 2003, we find out a similar trend by 16 Gus in Busan City. Second, the waste emission shows the positive relation with the number of population and the land by use. But there exists multicollinearity between population and the land by use, and the population is considered the main factor of waste emission. Third, the population causes 92% or more of the waste emission in Busan City, and future researches are required for the additional causes of waste generation.

Minimum Housing Standard is an instrument to cope with the problems of public health and community hygiene, deterioration of working class housing conditions appeared commonly in the process of capitalist industrialization and rapid rural-to-urban migration. This paper aims to examine the institutionalization of histories of minimum housing standard in the advanced countries, and analyze the spatio-temporal changes and characteristics of households failing to meet the New Minimum Housing Standard in Seoul Metropolitan since 1995. The analysis of this paper is based on the census data on population and housing. The results are as follows; Households failing to meet the New Minimum Housing Standard in Seoul are 501,000 households(1.368 million person, 14.4%). This means Seoul has overtaken the national average 11.8% for the first time and there are structurally marginal band of households who can not improve the housing conditions by themselves. In addition, the fact that the rate of Seoul households living in the marginal shelter including the basement and rooftop room is the highest in Korea means the housing quality issues of Seoul is serious. Spatial distribution of households failing to meet the standard is divided into the northeast area and the southwest area in Seoul. Main features of the households are female-headed families, middle and old-aged people, divorce families, lower educated people, under and graduate students, non-apartments, dweller in 15~20 year old houses.

Based on the consideration of the hourly patterns of the electricity power consumption, this study predicted the effectiveness of hybrid power generation system, which is composed with wind power generator and photovoltaic generator. And this case study is performed at Konrido, which is a affiliated island of Kyeongsangnam-do. As the results, it is obvious that it is not efficient to cover the whole electricity power consumption only with any single power generating system, because the hourly patterns of electricity power consumption, wind power generation and photovoltaic generation are quite different. And because the wind is being through almost 24 hours, it is also found out that wind power generating system with storage battery is the most efficient combination for this case study.

The purpose of this study is to analyze the distribution of the building area and find the characteristics of development density where the areas to perform special functions as residential, commercial, and business area in Seoul. As a result of classification of the regions with the component ratio of building area ratio by types, the greater part of Seoul is residential areas and only a small part of Seoul have business function. Contrary to the Kang-Nam business districts, the central business districts have few or no houses. It is concerned that the redevelopment projects, such as New-Town, make Seoul more high- density. The industrial area lost the attractiveness as a resident in spite of businesses or infrastructures. So the industrial area will be the best place for reduce journey-to-work distance if improve housing conditions. As well as management of density, management of use is also required for effective landuse and green-growth city.

This study investigates the effects of economic factors and forest environments on rural residential area development in seven north central states of the U.S. by focusing on the relative importance of not only economic factors but also forest environments by forest type as core drivers of residential development. An empirical model of locations and magnitudes of population changes since 1950 in the north central region is first constructed, and then a panel model with fixed effects for counties is used to explain population growth by age group over time at the county level. Then a set of three equations is estimated for three major age groups, and a cross-sectional model is estimated for the last time period that regresses county-level environmental amenity variables on fixed effects coefficients for counties. Finally, an equation explaining changes in rural housing density is estimated. The results imply that immigrant age is a key factor influencing the choice of the place of residence and that the effects of environmental amenity factors on population growth and subsequent housing development in a county vary according to the age group.

This study aims to empirically analyze the impacts of the topographic characteristics of residential areas and the characteristics of land use and transportation on average trip distance of the senior citizens in Busan Metropolitan city. Multiple regression is conducted to accomplish the purpose of this study, and the conclusions and policy implications of the analysis are as follows. First, the average and standard deviation of the residential areas are significantly related to average trip distance of the senior citizens. Thus, urban transportation policies need to take account of the topographic characteristics of the residential areas. Second, average distance from the nearest subway station and density of bus stops have positive and negative association respectively. Mobility improvement polices for senior citizens should consider urban spatial structure and different approach processes to transportation facilities by modes. Third, mobility and residential environment improvement policies for senior citizens should take into account different sociodemographic characteristics by locations. This shows that the mobility convenience policy for senior citizens is more necessary than any other policy for administrative dong, where traffic access is relatively low and the single senior citizen population is concentrated.

최근 다양한 기상 이변과 해수 온도 상승으로 인해 더욱 빈번하게 발생하고 있는 국지성 집중 호우 및 돌발홍수는 각 유역 특성별 수문 기초자료의 축적 및 분석을 더욱 요구하고 있다. 또한, 수문현상은 시간과 공간에 따른 큰 변동성을 가지고 있어 규명하기 복잡한 특성을 가지고 있다. 특히 산악지역이 많은 우리나라의 지형학적 특성과 최근의 집중 호우 특성 등으로 인하여 이러한 변동성이 더욱 커지고 있다. 집중 호우시 인명과 재산의 피해가 더 가중되는 도시 지역은 더욱더 중요하다. 도시지역의 수문 모니터링이 부족한 실정을 고려한다면 도시하천별, 소배수구역별 수문 관측 및 자료 분석이 절실하다. 우리나라 주거지역의 토지이용 형태를 반영하는 과학적이고 체계적인 도시하천 수문 모니터링시스템 운영 및 자료 축적, 제공이 필요하다. "도시홍수재해관리기술연구사업단"에서는 도시하천 유역의 수문현상 규명을 위한 기초 정보 축적을 위해 중랑천 유역에 시험배수구역(신내1 배수구역, 군자 배수구역, 어린이대공원 배수구역)을 운영하여 수문 관측 및 자료 분석을 수행하고 있다. 본 연구에서는 도시하천 시험유역의 운영 결과와 미흡한 부분을 개선하기 위해 보완한 내용을 소개하고자 한다. 또한, 도시하천 시험유역 운영시 인식해야할 중요한 사항에 대해 조사하였다. 이러한 결과는 향후 도시하천 시험유역 선정 및 운영, 수문자료 분석에 활용될 것으로 판단된다.

Even if Seoul City administration improved its public transportation service, transportation model share in seoul has not been increased. Subway user is also decreasing. Therefore, policy transition into TOD(Transit Oriented Development) should be applied in oder to enhance subway modal share. This paper develops a influencing model by using variables of transportation demand and supply. In addition, it provides major influencing factors for users in subway station area and level of transportation supply based on the analysis results. The results show that: first, cluster analysis presents that traffic pattern is proved to be different according to land use characteristics(residence, non-residence); second, main transportation variables such as transferring distance, the number of bus stop, the number of short distant bus lines, and the number of bicycle are more supplied in residential area compared to non-residential areas; third, the number of lines, bus dispatching interval, operating time, and distance between subway stations are more supplied in non-residential areas than residential areas. All in all, the results will be useful for providing priority of considerations in case of decision-making on public transportation policy in subway station area.
