  • Traffic noise pollution is a growing problem that highly affects the health of people in urban areas. In order to implement effective measures against traffic noise the noise mapping about its distribution is imperative. Urban traffic noise maps will help to establish the existing baseline so that we will be able to look for the effective way to control the noise. They will also let us see in an understandable and visual way how noise spreads from roads into residential areas. In this paper we considered three development types between roads and residential areas, and applied the interpolation of ArcGIS for noise attenuation with distance from the roads to find the noise level at the parcels positions in residential areas, and then generated the noise map using the interpolated results. Therefore we present results that the traffic noise level within residential areas exceed the national noise standard and also can estimate the noise level of individual parcels. These results can be used for traffic noise control planning or assessment of officially assessed land price in near future.

  • Recently people are starting to pay attention to the vacant house. Vacant house across the country are expected to be a Million. Ministry of Land, Transport and Maritime Affairs has created a new legal provisions regarding maintenance to Vacant on the Construction Law. But Vacant house information systems in government are not available Other countries to clarify the role each entity to manage these Vacant and manages the Vacant. The national government has made the operating budget support program for the Vacant management. The local government has made legislation of self-government to create a DB for the Vacant management. A non-profit corporation is developing a program operated by the Vacant, and the Vacant intermediaries to consumers. Therefore, our country is also to expand the national budget for the Vacant administration, local governments should establish a comprehensive management system for managing and providing Vacant house research and DB.

  • Today, rapid progress of urbanization is discovered commonly in many countries, especially in developing countries, which has led to spatial order and development process of city. Historically, Taegu was a walled city and formed mono-nucleus which was restricted by the castle. As the city grew gradually, the castle was removed as a result of diversification in traffic network, change of socio-economic environment, formation of industrial base and functional distribution. According to reconstruction maps of residential patterns, there was distinctive residential segregation among ethnic groups. Koreans in Taegu in 1939, aggregated densely in the southern and western parts of the city. The Japanese were concentrated densely in the northern and eastern parts of Taegu. And the street pattern within residential areas of the Korean people was shaped like a maze type in contrast with Japanese residential areas, which showed grid pattern of streets. This is another general pattern of almost all colonial cities, especially in Asia. Through this process, today it appears that, out of overall residential areas which occupy the highest ratio in urban land use, those for eminent people influence the functional development of urban spatial structure very heavily as a key point in urban residetial structure. Truly, residential segregation can be seen as the spatial manifestation of uneven distribution of such important scarce resources as housing and residential environment. In this study, the characteristics of locational distribution of the eminent people show their socially and economically stabilized standing in Taegu, taking the aforesaid situation as a background of the study. And the process of this study is as follows ; to examine the forming process of residential areas in the city as a theoretical supporting, to put in order on classical interpretation to formation of residential areas, and general type modern residential areas formation, and economic decision factor of land use. Therefore, this study aims to examine growth and development of eminent persons' residential areas and, at the same time, extract locational characteristics through the pattern of eminent persons' location and predict changes in the future.

  • There are a growing number of cases to expand balconies of apartments faced with open air in order to enhance functional satisfaction and efficiency of dwelling space. In case of the balcony expansion at the floor, however, it is difficult to exclude a possibility of bringing about internal condensation due to the difference of temperature between indoor air and outdoor air caused by the Inflow of outer low-temperature air through the upper part of ceilings by failure in completely putting together the outer composite wall panels on the aluminum curtain walls installed at outer walls This study is to forecast possible occurrence of internal condensation around parapets and H-beam located at the inside of balcony ceilings on the uppermost floor of super-high apartment buildings faced with open air in order to provide dwellers with more comfortable environment in the related space and get rid of their uneasiness about the condensation. In this study, we estimated internal condensation, which vary in accordance with humidity pressure distribution, at curtain walls, stone panels or lower parts of slabs that constitute outer space of the residence and are weak against heat, through temperature forecast and temperature distribution interpretation program at normal two-dimension temperature

  • 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.

  • The rental housing market in South Korea, specifically monthly rent with deposit, has been expanding over the last three decades (8.2% in 1990 to 21.0% in 2020), partly replacing the traditional Jeonse market. The distribution of rent has changed due to public rental subsidies and the emergence of luxury rental housing, while the distribution of rental household income has been polarized because of the emergence of rich renters. This study attempts to measure the structural changes in the rental market by developing a new indicator of income-rent mismatch. Using the seven series of the Korea Housing Survey, this study analyzed the changes in rent (reflecting the conversion rate) and income levels of rental households in 2006 (base year) and 10-15 years later (the analysis year) at the national level and at the spatial unit of 16 metropolitan cities and provinces (excluding Sejong), respectively, by dividing them into quartile data. The result reveals that rental housing was undersupplied in middle- and high-income rental housing due to the decline in the highest quartile (25%→18%) and the third quartile groups (25%→20%), while the supply of public rental housing expanded for the second quartile (25%→28%) and the lowest quartile (25%→35) groups. On the demand side, the highest income quartile shrank (25%→21%), while the lowest income quartile grew (25%→31%). Comparing the 16 metropolitan cities and provinces, there were significant regional differences in the direction and intensity of changes in rent and renter household income. In particular, the rental market in Seoul was characterized by supply polarization, which led to an imbalance in the income distribution of rental households. The structural changes in the apartment rental market were different from those in the non-apartment rental market. The findings of this study can be used as a basis for future regional rental housing markets. The findings can support securing affordable rental housing stock for each income quartile group on monthly rent and developing housing stability measures for a balance between income and rent distribution in each region.

  • Speceis composition and distribution by altitude of fish in the rock tide pools in Taean were determined using montly samples collected in the 9 tide pools from January to December 2010. Among 16 species collected, a forktongue goby Chaenogobius annularis was dominant accounting for 34.6% in the total number of individuals, and followed by Dictysoma burgeri (22.0%), Sebastes schlegelii (6.9%) and Tridentiger trigonocephalus (6.8%). A resident fish Dictyosoma burger occurred at all tide pools, and Chasmichthys dolichognathus was dominant in the upper tide pools and was collected throughout the study period. The resident fish is more abundant than the transient fish and occasional fish accounted for 61.4%, 14.2% and 24.4% in biomass, respectively.

  • 항만건설에 있어서 항만의 내부시설 중에서 무엇보다도 가장 중요한 시설물은 선박을 안전하게 접안시켜 하역할 수 있는 안벽시설물이다. 안벽구조 형식의 결정은 항만의 이용목적 등에 따라서 달라지지만 항만의 건설입지조건 등에 의해서도 달라진다. 안벽구조형식 중에서 잔교 식 안벽은 무엇보다도 단기간에 건설이 용이하여 지금까지 각국에서 널리 사용되어 왔고 장래에도 이용도가 증가되리라 생각한다. 최근에는 해안선을 이용한 위락시설이 건설되면서 잔교 식 안벽구조물을 설치하여 보조시설물로 이용하는 경우가 많다. 과거에 설계되어 잔교를 설계할 경우는 일반적으로 항내의 정온이 잘 유지되는 경우에 대해서 설치하는 경우가 많기 때문에 파랑에 의한 반사율과 잔교 상부에 작용하는 양압력을 고려해야할 필요성이 거의 없었다. 그러나 최근에는 태풍이 내습할 경우 기존의 항내로 높은 파랑이 침입하는 경우가 발생하고 있어 항내에서도 잔교의 파괴로 인한 자연재해가 대형화되는 경우가 발생하고 있다. 또, 처음부터 안벽을 설계할 때에 대형화의 잔교 식 안벽구조물을 설치하는 경우도 있다. 이런 잔교 식 안벽 구조물을 잔교의 상부 판에 작용하는 양압력 분포와 잔교 전면의 반사율 등이 구조물의 유지관리 등에 미치는 영향이 매우 크기 때문에 반사율 검토와 양압력을 고려한 설계가 필요하다. 본연구의 대상은 일정 해역에 잔교 식 안벽을 설계하고자 할때 최적의 안벽 설계가 될 수 있도록 수리모형실험을 실시하여 구조물의 안전과 항내정온에 기초가 되는 자료를 도출하고자 하였다. 따라서 본 수리모형실험으로 인한 연구는 잔교 식 안벽에 대한 반사율과 상부에 작용하는 양압력, 잔교말뚝(pile)에 작용하는 수평압력을 검토하여 잔교 식 안벽 설계에 기초자료를 제공하고자 한다. 혈청을 이용한 동결보존을 대체할 수 있을 것으로 생각된다.지에 더해주면 세포의 증식이 개선될 것이다. 그래서 몇 가지 첨가물을 이용해 세포의 증식력에 변화가 나타나는지 알아보았다. 첨가물을 이용한 실험에서 IGF-I의 경우 장기간 배양에서 세포의 수를 안정적으로 유지하고 계대 횟수를 증가시키는 효과를 보였다. 이는 IGF-I이 어느정도 세포의 증식을 유지시켜주는 역할을 하기 때문인 것으로 생각된다. 무혈청 배지에서 비적응 CHO 세포의 계대 배양에 한계가 있는 것은 세포주기가 멈추기 때문인 것으로 생각된다. 세포주기가 멈추는 growth factor와 같이 세포의 증식을 지속적으로 유도할 수 있는 물질이 무혈청 배지에서는 부족하기 때문인 것으로 생각되고, IGF-I과 같은 첨가물을 통해 극복할 수 있는 문제라고 여겨진다.관점과 주거교육가치관 요소와의 관계를 알아본 결과, 전통적 관점은 주거교육가치관 요소 중 오직 주거관리적 요소와 관계가 있었으나 그 정도는 낮으며 실천적 관점과 구조적 관점은 주거가치관의 각 요소에 따라 약간 다르기는 했으나 주로 보통의 관계를 보였다.군 순으로 높게 관찰되었다. 이상의 결과를 종합할 때, 임상에서 니켈-티타늄 합금 와이어에 굴곡을 부여하기 위해 열처리하는 경우 초탄성 특성은 유지될 수 있으나, 부하-변위 곡선의 상방 증가가 나타나므로, 와이어에 의한 교정력이 증가될 수 있음에 유의하여야 한다. $day^{-1}$인 인공습지), scenario 2(면적 4.2ha인 저류지)가 각각 연평균 6.9%, 4.8%, 7.1%의 감소를 보였다.
