The transferal of districts encircled with walls and the characteristics of newly formed districts' location, structure and view are analyzed in this study with an example of Nakan Eupseong in Suncheon, Jeolla-do, which shows the best case of restoration of districts and interior structures to the original state of those in Joseon Dynasty. The results can be summarized as following: First of all, the district of Nakan-gun has transferred in 1424 from today's Goeup-ri in Beolgyo-eup, Boseong-gun to Nakan Eupseong in Nakan-myeon, Suncheon-si. Secondarily, Nakan Eupseong, the newly formed district, followed the example of Hanyang, the capital city, almost exactly in location, structure, view, and etc, due to the drastically planned designs under the participation of the central government. Thirdly, the native forces of Nakan wanted to deny the new district till 1451, and the inertia of old district had strongly remained until the late 1400's. Last of all, Joseon dynasty's typical theory of divination based on topography was clearly systemized and stated in the materials written after the 1700's.

A short consumption cycle caused by the technological development and the diversification of customer lead to both the dynamic growth of the industry and the waste recycling issue at the same time. Including Korea, the situation is particularly worrisome in some countries, such as India and China, where acute environmental hazards have resulted from a combination of a lack of recycling centers' capacity and the domination of a large backyard recycling sector. A study about to maximize the current recycling center efficiency with minimal changes is required. In this study, we suggest the optimal location selection method for the recycling center based on the well-known reverse logistics cost minimization model. An actual recycling data about a specific electronic equipment and region in Korea are used for the verification of the method suggested.

This paper is to build a spatial decision support system designed to solve problems relevant to the decision-making for retail center locations. For construction of the system this paper discusses the primary procedures of spatial modeling and issues of data, which are required for integrating spatial interaction models to GIS having capability of managing, analyzing and visualizing spatial data sets. Lexington, Kentucky, is selected as a case study to implement the spatial decision support system based on the spatial modeling module. This system for retail center locations is useful of estimating the catchment areas more accurately and analyzing resultant flow patterns. And this system can make spatial analysis efficiently for what-if scenarios such as an intended retail center or changing demand. The benefits of adopting this system allow the decision makers to plan the investment strategies and search for stable market structure.

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.

We investigated geographical condition and soil characteristic of ginseng cultivation site. At all sites, crown density adjusted by 80%. and Air and soil temperature were also measured. The geographical condition vary ato all sites. and soil shows similar characteristics with typical forest soil of Korea. The results shows the Air temperature needs to be higher than $15^{\circ}C$ for seed budding at April When soil temperature reach at 8, leaf of foest ginseng starts to bud. A forest ginseng is influenced by forest type, planting type and budding rates. In the case of a seedling planting, an seeding emergence rate is high, but the rate is decreased rapidly after three years On the other hand, direct seeding shows lower seedling emergence rate, but survival rate is higher than seedling-planting.

This study shed light on searching spatial location pattern of movie theaters by operating screens in theater as proxy variable to find spillover effects and spatial determinants. After taking procedure to find spatial spillover effect by GIS 3D analyst, movie theaters in Seoul metropolitan area are formed in four categorized regions, such as Kangbuk, Kangnam, Kangseo, and Kangdong. Regions which have larger number of screens than others show that they affect to relevant regions directly. In addition, this study analyzes that people have tendencies to visit movie theater while they use other similar facilities such as music, publishing, and public performance facilities. Therefore, trend of agglomeration of similar enterprise including motion picture industry has a spillover effect and economy of scale when they are gathered in specific regions which are specialized as certain usage.

The number of patients with cardiovascular diseases who experience an out-of-hospital cardiac arrest (OHCA) are increasing among young adults as well as the aged population. An automated external defibrillator (AED) is vital in improving survival rates of OHCA victims. Survival rates of OHCA were shown to decline exponentially in time to defibrillation, yet studies in Korea are uncommon that captures the properties of their survival rates in examining optimal locations of AEDs. In this study, we worked on the maximal gradual coverage location problem (MGCLP) with exponential decay coverage function to decide on their optimal locations. The exponential decay coverage function mitigates the drawback of over-estimating survival rates of OHCA patients. It is expected that a more sophisticated facility location problem will be developed to identify the "emergent" characteristics of pedestrians who responds to the OHCA occurrence by incorporating random pedestrian locations and movement through simulation.

Seoul's public bicycle system, 'Ttareungyi,' introduced in 2015, has achieved an annual ridership of 40 million in 2022. Similarly, electric scooters, a type of personal mobility device, surpassed one million riders in 2020 due to various sharing platforms. However, the major roadways for these new transportation, bicycle lanes, are notably insufficient compared to other forms of transport. Hence, this study proposes an optimal location selection method for bicycle lanes in Seoul to prevent accidents and enhance bicycle ride safety. The location selection process prioritizes road safety concerning bicycle accident risk. Using regression models, high-risk areas for bicycle accidents are identified. Cluster analysis categorizes these areas into six clusters, each suggesting suitable types of bicycle lanes based on cluster-specific characteristics. We hope that this study will contribute to the improvement of Seoul's transportation environment, including the expansion of dedicated bicycle lanes and lanes for personal mobility devices.

In order to provide the basic information for restoration of vegetation, conservation of rare species and maintenance of biodiversity, changes of site factors and vegetation by human trampling disturbance were investigated at the subalpine zone near the peak of Mt. Sorak in Korea. The destructed vegetation was found mainly in the southern parts with gentle slope in this study area. Height and coverage of vegetation and the species diversity decreased, and the community structure depended on trampling strength. Soil moisture, organic matter contents and litter thickness in the site with destructed vegetation by human trampling showed lower values than in the undisturbed site. Soil depth decreased, and gravel exposure on the ground surface increased by soil erosion responded to trampling strength.

본 연구의 목적은 정기시장을 이용하는 이동 상인과 소비자의 특성을 분석하여, 정기시장의 중심지 기능과 공간 구조를 이해하려는 것이다. 충청북도 영동군 지역을 사례로 해서 8개의 정기시장을 이용하는 상인에 대한 면접 조사와 소비자에 대한 설문 조사를 통해서 자료를 수집하였다. 정기시장의 연구는 경제-입지적 접근 방법이나 사회-문화적 접근 방법으로 행해지지만, 정기시장의 기능을 상인과 소비자의 두 측면에서 모두 고려할 필요가 있다. 본 연구에서 고차위 중심지에 위치한 정기시장은 규모가 커진 반면, 저차위 중심지에 위치한 정기시장은 쇠퇴하고 있는 것이 확인되었다. 정기시장을 유지시켜 왔던 사회적 관성과 비교 우위는 농촌의 근대화 과정에서 점차 사라지고 있으며, 이러한 사회경제적 변화가 정기시장을 쇠퇴시키고 있다.
