This study examined the key factors that significantly improved the demand of multi-habitation. It determined the factors at the macroscopic level (or push factors) and the microscopic level (or pull factors). Focusing on a microscopic viewpoint, this study looked at the process of settlement through investigating 78 MH residents in the Seoul metropolitan area. The survey included the questions, such as who they are, how they prepared for moving, and how much they enjoyed their rural lives. In addition, any differences in this process were analyzed depending on respondents' characteristics. Major findings are as follows: First, general macro-level circumstances seemed supportive for the MH lifestyles. Second, six keywords were determined to represent the recent MH trends. They are "semi-sedentism, clustering, young people, female, money, and policy". Third, the distances between the original towns for native residents and new second-home towns for MH residents affected the interactions among them. However, these two groups had better relationships when the second-home towns were apart from the original towns. I then considered the need of a buffer zone between the two residential areas for MH residents. The conceptual difference between MH residents (i.e., semi-sedentism) and original rural residents (i.e., sedentism) might require certain types of buffer zones to continue good relationships among them.

To find out the status and characteristics of exotic plants in the Gwangreung Forest, a representative forest ecosystem in central Korea, we surveyed the species composition, coverage, and habitat illuminance of exotic plant species in a set of quadrats established along roads and trails in and around the Gwangreung Forest and buffer zone areas, In 1932, only five species of exotic plants were found along paths and roads in the Gwangreung Forest. However, the number of species in the forest has dramatically increased since 2000, when Ambrosia artemisiifolia L. and A. trifida L. were first recorded, and in 2007, 38 species of exotic plants were recorded. Among the 11 families, 23 genera and 25 species of exotic plants recorded in the quadrats, Compositae was the most common family (11 species), and perennial herbs, 42%, were the most frequently occurring life type, followed by annual herbs (31%) and biennial herbs (19%). Plants of North American origin comprised 48% of exotic species identified in our surveys. Exotics were found most frequently in quadrats along roads in the forest, followed by the buffer zones and hiking trails. The number of species and individuals of exotic plants decreased as we moved deeper into the forest, but Aster pilosus Willd. and Erigeron annuus (L.) Pers. were identified along hiking trails in the interior, and appeared to be capable of spreading further and more rapidly into the forest than other species.

본 연구는 대구시 지산 하수처리장을 사례로 환경기초시설의 입지가 지가의 차이에 미치는 영향을 분석하였다. 이를 위해 지산 하수처리장으로부터 200m 단위로 400m까지 두 개의 구역을 각각 설정하고 총 822개의 개별공시지가 자료를 취득하였다. 지산 하수처리장 설립 전후의 지가의 차이를 비교하기 위하여 대응표본 t 검정을 실시하였다. 그 분석 결과, 각 구간의 지가가 하수처리장 설립 후 약간 상승하였고, 이러한 차이가 유의한 것으로 나타났다. 또한, 하수처리장 설립 전에는 200m 이내의 평균 지가가 200-400m의 평균 지가 보다 낮았지만, 설립 후에는 양 구간에 평균 지가의 차이가 거의 없었다. 지산 하수처리장은 악취가 거의 나지 않고 하수의 처리 용량이 적으며 그 주변지역은 대부분 상업시설이나 주거시설로 이용되고 있어서 기존의 연구와 달리 하수처리장의 입지가 주변 지가의 하락에 거의 영향을 미치지 않은 것으로 나타났다. 본 연구의 결과는 환경기초 시설의 입지로 인해 갈등하는 정부와 지역 주민들에게 새로운 근거자료로 제시될 수 있을 것이다.

홍수는 도시가 피할 수 없는 자연재해이다. 홍수 재해는 도시의 경제와 안전, 그리고 지속발전을 심각하게 저해한다. 수변 공간에 대한 개발과 건설 과정에서 기본적인 방재시설의 건축을 통해 홍수의 경제적 피해를 줄이고자 막대한 자본을 투입하더라도 이를 완전히 피할 수는 없으며. 재해 발생 후 도시의 재건 비용은 방재(防災)시설의 건설비용보다 훨씬 많은 비용을 필요로 한다. 최근 몇 년간 도시재건 등에 있어 탄성(resilient)이론은 학계의 광범위한 토론과 주목을 불러일으키며 도시의 문제해결에 관한 주제가 되어왔다. 즉, 탄성의 방재개념을 이론과 경험적 요소를 토대로 어떻게 실천으로 전환시켜야 하는지가 도시방재가 마주하고 있는 현실적 문제이다. 본 논문은 도시의 수변(공간) 완충지역(홍수 취약지역)여 관한 이론 문헌과 도시의 실천 사례연구를 통해 탄성 방재이론인 5R 요소를 명확화하고, 이에 따른 상세 대책을 제시하고자 한다. 또한, 도시의 수변완충지역을 중심으로 탄성 방재이론 요소의 도시수변(공간)계획에서의 실행 가능성을 강조하는 동시에 다음과 같은 두 가지 문제를 해결하고자 한다. 첫째, 방재계획수단을 이용해 도시수변토지의 개별 효용과 수변완충지역의 방재기능 간의 갈등을 완화하는 것과 둘째, 수변완충지역이 탄성 방재계획을 통해 방재 측면에서 홍수가 수반하는 문제에 최대한 대응할 수 있게 하는 것이다.

The purpose of this study is to analyze the characteristics of healing environments of the wards in women's hospitals. A evaluation checklist of the healing environment was applied to seven women's hospitals that have constructed or remodeled since 2000. The findings indicate that the comfort was well considered in most spaces, while the privacy and the nature-friendliness were insufficient. The lacks of balconies, terraces, landscapes, and water spaces for the nature-friendliness were also problematic. Among the patients' room, corridor, and patients' lounge, the lounge was the most negative in terms of healing environments. In order to improve the patients' privacy, soundproofing materials and buffer zones in the lounge should be considered. The future study needs to develop advanced survey and interview methodologies in order to support the relevant results.

The Palaces of Chosen dynasty in Seoul had lost its original features. The external appearance of the buildings that remains in palace nowadays, have got former conditions, but its enteriors are reconstructed or removed So we have a little knowledge of interiors of palace buildings, expecially of the door and window system. To clear up ambiguity of what kinds of door are selected, and sorts of using methods are prevailed, we must persuit from the latest building to the older building, and compare with documents. For that purpose the Chukchodang of Toksu palace is selected, which reconstructed in 1904, and compared with the document published in 1906. The consequence of investigation is that the palace buildings were adopted double or triple window system, and the main room have buffer zones, such as corridors or small rooms. And the main rooms were facing with wall paper, so metal fittings are hidden and wooden surfaces are hardly expose for the purpose of amenity.

The Korean government has purchased land properties alongside any significant water bodies before setting up the buffers to secure water qualities. Since the annual budgets are limited, however, there has always been the issue of which land parcels ought to be given the priority. Therefore, this study aims to develop efficient mechanism for land acquisition priorities in stream corridors that would ultimately be vegetated for riparian buffer zones. The criteria of land acquisition priority were driven through literary review along with experts' advice. The relative weights of their value and priorities for each criterion were computed using the Analytical Hierarchy Process(AHP) method. Major findings of the study are as follows: 1. The decision-making structural model for land acquisition priority focuses mainly on the reduction of non-point source pollutants(NSPs). This fact is highly associated with natural and physical conditions and land use types of surrounding areas. The criteria were classified into two categories-NSPs runoff areas and potential NSPs runoff areas. 2. Land acquisition priority weights derived for NSPs runoff areas and potential NSPs runoff areas were 0.862 and 0.138, respectively. This implicates that much higher priority should be given to the land parcels with NSPs runoff areas. 3. Weights and priorities of sub-criteria suggested from this study include: proximity to the streams(0.460), land cover(0.189), soil permeability(0.117), topographical slope(0.096), proximity to the roads(0.058), land-use types(0.036), visibility to the streams(0.032), and the land price(0.012). This order of importance suggests, as one can expect, that it is better to purchase land parcels that are adjacent to the streams. 4. A standard scoring system including the criteria and weights for land acquisition priority was developed which would likely to allow expedited decision making and easy quantification for priority evaluation due to the utilization of measurable spatial data. Further studies focusing on both point and non-point pollutants and GIS-based spatial analysis and mapping of land acquisition priority are needed.

In Korea, where the plain land is greatly deficient as a mountainous nation, most of riparian zones were transformed into agricultural fields and urban areas. Excessive use of the land, which is close to river, makes the rivers enduring severe pollution stresses. Disappearance of riparian buffer, which plays a function of filter in the riverside, appears as a main factor aggravating water pollution of rivers. In this respect, it is imperative to restore the lost riparian vegetation. This study found out restoration models of riparian vegetation from the Bongseonsa stream, which has remnant riparian vegetation patches as a conservation reserve. Feasible reference information applicable for restoration of riparian vegetation was shown in the species level in the order of herb, shrub, and tree and sub-tree zones as far away from the waterway. Those information could contribute to restoring integrate and healthy rivers and streams beyond simple landscaping differently from the other restoration projects when they will be applied to the restoration project to be carried out in the future. In addition, the spatial range of river and stream, background that riparian zone disappeared in Korea, and application plan of the obtained reference information were discussed.

This paper presents a novel and efficient data transmission scheme based on mobile edge computing for the massive IoT environments which should support various type of services and devices. Based on an accurate and precise synchronization process, it maximizes data transmission throughput, and consistently maintains a flow's latency. To this end, the proposed efficient software defined data transmission scheme (ESD-DTS) configures and utilizes synchronization zones in accordance with the 4 usage cases, which are end node-to-end node (EN-EN), end node-to-cloud network (EN-CN), end node-to-Internet node (EN-IN), and edge node-to-core node (EdN-CN); and it transmit the data by the required service attributes, which are divided into 3 groups (low-end group, medium-end group, and high-end group). In addition, the ESD-DTS provides a specific data transmission method, which is operated by a buffer threshold value, for the low-end group, and it effectively accommodates massive IT devices. By doing this, the proposed scheme not only supports a high, medium, and low quality of service, but also is complied with various 5G usage scenarios. The essential difference between the previous and the proposed scheme is that the existing schemes are used to handle each packet only to provide high quality and bandwidth, whereas the proposed scheme introduces synchronization zones for various type of services to manage the efficiency of each service flow. Performance evaluations show that the proposed scheme outperforms the previous schemes in terms of throughput, control message overhead, and latency. Therefore, the proposed ESD-DTS is very suitable for upcoming 5G networks in a variety of massive IoT environments with supporting mobile edge computing (MEC).

This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.
