  • 오염토양의 현장정화에 있어서 지반 및 오염물질의 물성치는 정화에 소요되는 시간과 함께 매우 중요한 고려사항이다. Gabr 등(1996)은 연직배수재가 설치된 오염지반에서 시 공간적 변화에 따른 초기오염농도에 대한 오염농도비($C/C_0$)를 구하는 식을 유도하였다. 본 연구에서는 Gabr 등이 유도한 식의 전산모형 FLUSH1을 이용하여 오염지반 흙의 유효입경, 간극률, 형상계수, 밀도, 지반의 온도와 오염물질의 단위중량 및 점성계수가 오염정화에 미치는 영향을 알아보기 위하여 시 공간적 변화에 따른 오염농도비($C/C_0$)를 분석 하였다. 분석결과 연직배수재가 설치된 오염지반에서 정화에 크게 영향을 미치는 인자는 오염지반 흙입자의 유효입경인 것으로 나타났으며, 그 다음으로 오염물질의 점성, 오염지반 흙의 간극율, 형상계수, 지반의 온도, 오염물질의 단위중량, 흙의 밀도 순으로 분석되었다. 오염지반 흙의 밀도는 오염정화에 미치는 영향이 아주 작은 것으로 나타났다.

  • 부동산 시장 분석에 있어 기본이 되는 정량적 데이터는 부동산 가격 지수이다. OECD와 같은 국제기구에서는 국가별 부동산 가격 지수를 공표하고, 한국부동산원에서는 광역시 단위와 시군구 단위의 지수를 산출한다. 그런데 공간단위를 시군구보다 정교한 동단위, 아파트 단지 단위로 설정하는 경우, 여러 문제점을 맞이하게 된다. 대표적인 문제는 결측치이다. 공간적 범위를 좁힐수록 단위 기간에 따라 거래가 적거나 아예 존재하지 않는 경우가 존재하기에 이 경우에는 지수의 산출이 불가능한 결측치가 발생할 수 있다. 본 연구에서는 지도학습 기반의 머신러닝 기법을 활용하여 특정 범위와 기간에 거래가 존재하지 않아 발생할 수 있는 결측치를 보완하는 기법을 제안한다. 본 모형을 통해 부동산 매매 지수의 실제값이 존재하는 것들의 예측을 통해 그 정확도를 검증하고 결측치가 발생한 것들의 예측도 해 볼 수 있었다.

  • Representative meteorological data of the rural water district, which is the spatial unit of the study, was produced using the grid-based national standard RCP scenario rainfall data provided by the Korea Meteorological Administration. The retrospective reproducibility of the climate model scenario data was analyzed, and the change in climate characteristics in the water district unit for the future period was presented. Finally the data characteristics and differences of each meteorological element according to various spatial resolution conversion and post-processing methods were examined. As a main result, overall, the distribution of average precipitation and R95p of the grid data, has reasonable reproducibility compared to the ASOS observation, but the maximum daily rainfall tends to be distributed low nationwide. The number of rainfall days tends to be higher than the station-based observation, and this is because the grid data is generally calculated using the area average concept of representative rainfall data for each grid. In addition, in the case of coastal regions, there is a problem that administrative districts of islands and rural water districts do not match. and In the case of water districts that include mountainous areas, such as Jeju, there was a large difference in the results depending on whether or not high rainfall in the mountainous areas was reflected. The results of this study are expected to be used as foundation for selecting data processing methods when constructing future meteorological data for rural water districts for future agricutural water management plans and climate change vulnerability assessments.

  • The sense of crisis regarding regional extinction due to low birth rates and an aging population is expanding. Generally, the local extinction index is used to analyze local extinction. However, it is challenging to diagnose the actual situation of village extinction risk in rural areas, even though the regional extinction index can be analyzed in units such as Si-Gun-Gu and Eup-Myeon-Dong. This difficulty arises because the regional extinction index solely relies on natural population growth indicators (elderly population and female population aged 20-39). Therefore, the purpose of this study is to develop a village extinction index that can identify the disappearance of rural villages. Additionally, the aim is to apply the developed indicators to the village (administrative ri) spatial unit. The existing regional extinction index used only mortality-related indicators as factors for natural population decline and fertility-related indicators as factors for natural population growth. However, the developed village extinction index included not only the factors of natural population change but also incorporated social population growth factors and factors related to the pace of village extinction. This is the key difference between the developed village extinction index and the existing regional extinction index. In this study, the indicators of "total population," "number of young women aged 20-44," "number of elderly population aged 70 or older," and "number of incoming population" were selected to develop a village extinction index. The village extinction index was developed by incorporating both natural population growth indicators and social population growth indicators. The developed village extinction index was applied to administrative villages. This research is expected to provide a more accurate understanding of the current state of rural villages facing extinction.

  • This study aims to identify the rural spatial structure and to establish the planning characteristics based on urban-rural connections strategy of North Korea. For this purpose, they were collected such as documents and drawings including primary data related to rural planning in North Korea, and the rural space were classified into three elements in order to analyze them by the rural planning's point of the view. Unlike generalized capitalist cities, socialist North Korean cities are characterized by the coexistence of urban and rural areas. This distinct feature of the city is also reflected in creating rural space in North Korea. Thus, The urban-rural integration in spatial planning is a key factor in understanding the spatial structure of North Korea. This study firstly examines the characteristics of the county(gun), the administrative and economic unit established in the post-war period, secondly, examines the planning method of town(eup) which can be called the urban center in rural areas, and lastly grasps the planning method of rural village focusing on collectivization and identifies how they are connected to the town for the shake of urban-rural integration. As a result, the characteristics of rural planning in North Korea has revealed that it has a comprehensive rural planning established with the goal of strengthening the self-sufficiency of the rural area by the means of the create of rural spatial hierarchy in the whole country.

  • According to Plato's ontology, we lead our lives by establishing a relationship with others in the society. However in rapidly changing era, our lives was gradually moving towards personal tendency. Even for the relationship with family, not with others. Thus, awareness about owning properties has changed due to the sociocultural factors and increase number of single-person households. So in this study, the considerations for single-person housing were perceived through preceding research, and the elements making spatial boundary of shared housing were drawn to make rational space sharing based on the boundary with others and of the living environment. With overall analysis based on the spatial boundary features of planned shared housing, the plan characteristics according to the spatial boundary of the current shared housing is to be drawn and analyzed. Third, The expressive and structural features of spatial boundary as above appear with mutual flexible connectivity, And the result shows that the modularity was the highest. Among them variable coupling modularity of shows how it is possible to combine efficiently and variously the private and public spaces with regularity of 'space of optimal unit'. This study drew plan characteristics from more detailed space border of shared housing. Therefore, The basic framework of the characteristics spin for the cases that newly emerge later on.

  • 공간적 지역성(spatial locality) 및 시간적 지역성(temporal locality)을 동시에 향상시킬 수 있는 새로운 고성능 데이터 캐시 구조를 제안한다. 제안된 캐시 메모리는 하드웨어 프리패치 유닛과 큰 블록 크기를 갖는 직접사상(DM: direct mapped) 캐시와 작은 블록 크기를 갖는 완전 사상(FA: fully associative) 캐시의 하위 캐시 유닛으로 구성된다. 공간적 지역성은 블록 데이터를 패치하여 직접 사상 캐시에 저장함으로써 보장되며, DM 캐시 히트가 발생한 경우에 그 이웃 데이터 블록을 프리패치 함으로써 최적화 된다. 시간적 지역성은 작은 블록 데이터가 DM 캐시로부터 제거 될때 그 블록의 과거 기록에 따라서 중요한 데이터는 완전사상 캐시에 저장함으로써 보장된다. Spec2000 벤치 마크 프로그램에 대한 실험 결과에 의하면 제안된 캐시 구조는 비슷한 크기의 직접사상 캐쉬, 4웨이 연관사상(4 way set associative cache) 및 SMI(selective-mode intelligent cache) 캐쉬 [8]등의 기존의 구조에 비해서 미스 비율(miss rate)을 평균적으로 $12.53\sim23.62%$ 그리고 AMAT(average memory access time)를 평균적으로 $14.67\sim18.60%$ 줄일 수 있음을 증명하였다.

  • This study aims at analyzing of residents'attitudes and spatial structures in the rural villages reconstructed by the Rural Village Improvement Project(type A), and suggesting the guiding directions for planning rural villages. Six rural villages located in KyungGi province were selected for case study. The Major findings can be summarized as follows : 1) The ratio of type A project(newly planned village) in the total cases of the Rural Village Improvement Project has increased since 1990, In the majority(91.2%) of the type A project, the project area is below 2 ha and density of dwelling unit is below 40 households/ha. 2) The three spatial structures of newly planned rural village, i.e., Loop pattern, Cul-de-sac pattern, and Dendritic pattern, are identified. And the barns in the newly-build houses are categorized into the five types : the vertical addition type, the horizontal addition type, the vertical- horizontal addition type, the no- barn type, and the reused -barn type. 3) In the newly planned rural villages, the level of satisfactions for the quality of house and water & sewer system is remarkably higher than in the existing rural villages. These are the positive effects caused by the Rural Village Improvement Project. 4) The majority of the villagers think the improvement of the existing rural village, instead of redevelopment or newly planned village, is most desirable, which means the improvement of houses, roads, and sanitary facilities while preserving the spatial structures of the existing village.

  • The purpose of this study was to investigate the residents' use and occupancy-behavior in the activity areas of the senior nursing facilities, and to provide basic information to establish the appropriate physical elements for planning the activity areas. For the study, the observations in five facilities were conducted for one day, from 10 a.m. to 4 p.m by four researchers. The results of the study are summarized as follows: First, most of the using behaviors in the activity areas were the doing nothing or sleeping. The meals and program services were provided in only one activity area of the floor and it showed that the unit care system was perfunctorily conducted at those facilities. In the representative activity area, its openness was the main physical element influencing the spatial using frequency, while the accessibility and the openness in the sub-activity area were most important. The seating arrangements having comers were helpful for residents' interactions. Second, while facility programs and meals were provided in the specific activity area, there was no residents' occupancy in other activity areas at the same time. There were interactions including residents' conversations and watching/observations in non-designated activity areas such as the nursing stations and near corridors. But the residents' interactions and self-regulations were blocked by absence of territoriality, monotonous spatial compositions and furniture arrangements, insecurity of residents' privacy, wide or narrow areas, and isolated spatial type. Based on the results at the above, basic guidelines for planning the activity areas of senior nursing facilities can be proposed as follows: First, the isolated type and the sight interception should be avoided in representative activity areas. It should be partitioned with couple of areas through the appropriate furniture arrangements, and be prepared semi-private spaces in non-designated areas such as nursing station for the interactions among the residents and the staff. Second, in activity areas for small group, the isolated type is not also good for the residents' accessibility. The residents' privacy should be confirmed through the various spatial compositions, and enough areas need to be sure for the diverse furniture arrangements.
