This paper is an analysis of the Category Individual Residence urban spatial structure along the National Route 20 (Koushu-Kaido), one of the major roads in Japan, and the degree of differences between locations and its changes between the points of time. The analysis was based on the GIS technique. Whilst, previous studies were based on municipal boundaries or mesh units as sources of data, GIS allowed the use of variable geographical units, Roadside zone, Inner zone, North zone, South zone, Blocks. As an example to apply the technology of GIS, 1986's sand 1991's building polygon data of the Urban Planning Bureau of Tokyo Metropolitan Government are used. The layers referred to the analyses is the building polygons with the amount of stories, building area, floor area and the material of the building. Two statistical analysis are executed; one is the test of the regional equality about the number of story of building, building area, floor area and fireproof building ratio.

The present study is the first report of molecular variations in different accessions of Rauvolfia tetraphylla L.f, a medicinally important plant collected from seven locations of Andhra Pradesh, India. Molecular analysis was carried out using RAPD markers. Out of the 40 primers screened from OPA and OPC Kts, a total of 205 scorable polymorphic markers out of 397 total markers were generated. Polymorphism of 51.6% was found with 3 unique markers. Levels of genetic diversity within accessions i.e., the genetic distance ranged from 0.816-0.932. Cluster analysis based on Dice coefficient showed two major groups indicating that mostly in cross-pollinated plants, high levels of differentiation among accessions exists independent of geographical distance. Hence the results of the present study can be seen as a starting point for future researches on the population and evolutionary genetics of this species. Understanding such variation would also facilitate their use in various conservational management practices, rootstock breeding and hybridisation programmes.

The facility location in designing a supply chain network is an important decision problem that gives form, structure, and shape to the entire supply chain system. Location problems involve determining the location, number, and size of the facilities to be used. The optimization of these location decisions requires careful attention to the inherent trade-offs among service time, inventory costs, facility cost, transportation costs. This paper presents a strategy that provides the best locations of distribution centers using GIS(Geographical Information System) assuming the limitation of delivery time. To get the best strategy of the location of distribution centers, we use the new loss functions as a penalty when the delivery time is violated

Visitors to a Web site leave access logs documenting their activity in the site. These access logs provide a valuable source of information about the visitors' access patterns in the Web site. In addition to the pages that the user visited, it is generally possible to discover the geographical locations of the visitors. Web servers also records other information such as the entry into the site, the URL, the used operating system and the browser, etc. There are several Web mining techniques to extract useful information from such information and visualization of a Web log is one of those techniques. This paper presents a technique as well as a case a study of visualizing a Web log.

Mandatory registration of clinical trials in public registry can ensure the transparency of clinical trials. Public clinical trial registry of can provide current chronological and geographical distribution of clinical trial throughout the country. We used public clinical trial registry provided by Ministry of Food and Drug Safety to analyze current status of clinical trial from 2014 to 2016 in South Korea. The number of clinical trials in antineoplastic and immunomodulating agents area was the greatest, followed by cardiovascular system and antiinfectives for systemic use as a whole. From 2014 to 2016, overall number of clinical trials decreased while the number of phase I clinical trials increased. Seoul accounted for more than half number of clinical trials in Korea. Supports for clinical trials in non-metropolitan area needs to be considered.

Geographic Information Systems (GIS) is considered to be one of the most important technologies provided by the Internet in our era. GIS enables institutions and individuals to plan and make decisions in many fields. GIS assists in accessing new and updated information on planning process. GIS also enables determining distances such as length, width, area on a map, and allows analyzing and processing a large amount of data for the search of geographical characteristics of locations. This paper explains the concept of dispensing prescription through the specific code of drug on an electronic system using GIS technology. The proposed methodology aims to inform patients of all the prescriptions dispensed and to help individuals inquiring about prescription at the nearest pharmacy through GIS technology. This proposed methodology is considered significant in some cases, as the patient does not know price, specifications and pharmacy location where the drug required is available, thus increasing the time and effort cost that is spent searching for the prescription.

During wartime, the operation of engineering equipment plays a pivotal role in bolstering the combat prowess of military units. To fully harness this combat potential, it is imperative to provide efficient support precisely when and where it is needed most. While previous research has predominantly focused on optimizing equipment combinations to expedite individual mission performance, our model considers routing challenges encompassing multiple missions and temporal constraints. We implement a comprehensive analysis of potential wartime missions and developed a routing model for the operation of engineering equipment that takes into account multiple missions and their respective time windows of required start and completion time. Our approach focused on two primary objectives: maximizing overall capability and minimizing mission duration, all while adhering to a diverse set of constraints, including mission requirements, equipment availability, geographical locations, and time constraints.

With the advancement of artificial intelligence and its various use cases, accessing it through edge computing environments is gaining traction. However, due to the nature of edge computing environments, efficient management and optimization of clusters distributed in different geographical locations is considered a major challenge. To address these issues, this paper proposes a centralization and automation tool called KubEVC-Agent based on Kubernetes. KubEVC-Agent centralizes the deployment, operation, and management of edge clusters and presents a use case of the data transformation for optimizing intra-cluster communication. This paper describes the components of KubEVC-Agent, its working principle, and experimental results to verify its effectiveness.

본 연구는 대한제국기에 그려진 '완산도형(完山圖形)', '조경단비각재실도형(肇慶壇碑閣齋室圖形), '전주건지산도형(全州乾止山圖形)' 그리고 '조경묘경기전도형(肇慶廟慶基殿圖形)' 등 4매 고지도의 제작의도 및 각 도형의 경관, 조망, 시점, 경물 등의 표현내용 및 방법의 특성을 고찰하고 도형 상호간의 관련성 분석을 통해 지형표현의 특질과 조망구도 그리고 내포된 상징경관의 의미를 고찰할 목적으로 시도되었으며, 문헌조사와 병행, 지도를 통한 관찰조사를 수행하였으며 현장조사 위성사진 인터넷조사를 통해 다음과 같은 결과를 얻었다. 전주가 조선왕실의 본향이라는 역사성을 확보하는데 중심적 공간인 경기전(1410) 조경묘(1771) 조경단(1899)은 왕조의 정통성 부여와 왕권강화의 일환으로 건립 중건되었고 조선왕조 초기부터 대한제국시기까지 정신적 지주 역할을 하면서, 지속적으로 유지 및 관리되었다. 4개 도형은 국호를 대한제국으로 변경한 후 황실과 황제의 위엄성과 당위성을 정당화하기 위해 국가적 차원에서 집중적으로 그려진 조선왕실의 시조 이한(李翰)의 묘소를 알리는 산형도(山形圖)와 그에 부속되는 보조도면으로 파악된다. 즉 완산도형은 전주부에서 조경묘, 경기전, 조경단의 존재를 알리고 그 위치를 파악하기 위한 키맵(key map)이며 건지산도형은 풍수국면도로서 시조묘의 풍수적 정당성을 강조하기 위한 것으로, 조경단비각재실도형은 이를 보다 세밀히 보여주기 위해 상세부분도로서 그려졌다. 전주건지산도형과 조경묘경기전도형은 공히 이원적축적과 부감법을 사용하고 주산을 건지산으로 삼고, 왕자봉과 의묘소(疑墓所)를 중심으로 중요지형을 실제 지형보다 과장해서 표현하였다. 또한 묘지에서 관찰되지 않는 중요 지형은 시점 이동을 통해 관찰하고 이를 세밀하게 표현하였다. 4벌 1조의 지도라는 측면에서 볼 때 '완산도형'은 군현도이며 위치도의 성격을 보이는 반면 '조경묘경기전도형'은 부분상세도로서 배치도로써의 기능을 보인다. 또한 '전주건지산도형'과 '조경단비각재실도형'은 산형도로서의 기능을 갖는 풍수형국도이자 상세도인 것이 확인되었다. 이와 같은 특성으로 볼 때, 기존 고지도와는 달리 연계도면(serial map)으로서의 기능성이 강화된 것으로 보인다.

최근 태양광의 발전 효율성과 경제성이 높은 발전소 부지를 확보하기 위해 특정 지역을 대상으로 태양광 발전량을 정확히 예측하기 위한 연구들이 수행되었다. 하지만 국내의 경우 기존 발전량 데이터가 부족함에 따라 정확한 발전량 추정에 문제가 발생할 수 있으며, 우리나라 기준으로 어떠한 기상조건을 나타내는 변수가 태양광발전에 어느 정도의 영향을 미치는지에 대한 연구가 부족한 실정이다. 따라서 본 연구는 지형 효과를 충분히 고려하여 제작된 태양복사에너지 지도와 미세먼지와 같은 기상조건을 추가하여 태양광 발전량 추정 회귀모델을 제시하고, 추정된 발전량과 실제 발전량을 비교 분석하였다. 그 결과, 습도를 제외한 태양복사에너지, 온도, 풍속, 운량, 강수량, 일조시간, 미세먼지가 발전 효율에 통계적으로 유의미한 영향을 미치는 것으로 나타났으며, 회귀 분석모델을 통해 추정된 발전량과 실제 발전량을 비교 분석하여 RMSE는 48.261(h), nRMSE는 1.592(%), MAPE는 11.696(%), 그리고 는 0.979이 도출되었다. 이러한 결과는 국내 태양광 발전 부지를 평가함에 있어서 고려해야 하는 중요한 기상 조건 등 태양광 발전량 추정 모델을 설계하는데 활용할 수 있으며, 이를 바탕으로 태양광 발전소 건설 부지를 선정함에 있어 중요한 지표인 발전량을 정확히 추정하는데 기여할 것으로 사료된다.
