In the homepage of 16 municipal provincial office of education, school information service displays text-based results through search step or presents the simple information of the selected area when an area is clicked on the static image map. And it has several problems such as server load and slow transfer speed by the search of the synchronous transfer. Thus, in this study, we used the open API of Google map to provide location-based school information and implemented the mash up service for school information with the Ajax program of asynchronous transfer to reduce server load and to increase transmission speed. This service gives the efficiency and convenience to students, teachers, parents and education family members of various levels because it includes the location with school information on a dynamic map.

Unlike existing Open APIs, Linked Data are made as a huge intelligent base to perform high-level SPARQL queries, and it is possible to create efficiently a new content by mashuping different information from various datasets. This paper implements a responsive web application for location-based semantic search. We mashup DBpedia, a kind of Linked Data, and GoogleMap API provided by Google, and provide a semantic browser function to confirm detail information regarding retrieved objects. Our system can be used in various access environments such as PC and mobile by applying responsive web design idea. The system implemented in this paper compares functional specifications with existing systems with similar functions. The comparison results show the superiority of our system in various aspects such as using semantic, linked-based browser, and mashup function.

The relationship between a service provided via the information system and user satisfaction has been thought of as an important factor for the development of a new service for the information system. In this study, the twelve new key services that are applicable to national R&D report system were derived by web environment changes in step with IT technology developments in order to support the new service for the user. The twelve new key services are as follows; semantic search service for national R&D report, associated report service, RSS service, mesh-up service, topic-map service, open API service, personalized service, collective intelligence service, SNS service, unstructured data service, detailed search service, mailing service. To assess the quality attribute of the twelve new key services in the national R&D report system, a survey was performed. In conclusion, a stepwise service plan for the national R&D report system was proposed which would use the satisfaction coefficient and the results of the service classification. The following step-by-step service should be developed by in this way. The unstructured data service, personalized service, associated report service, topic-map service, open API service, and the collective intelligence service are needed to develop the first step and RSS service, mesh-up service, semantic search service for the national R&D report, mailing service, detailed search service, and SNS service are needed to develop the second step.

Content used in mashups is typically obtained from a third party source through a public interface or API (web services). Other methods of obtaining content for mashups include Web feeds (e.g. RSS or Atom), and screen scraping. A mashup or meshup Web application has two parts: A new service delivered through a Web page, using its own data and data from other sources. The blended data, made available across the Web through an API or other protocols such as HlTP, RSS, REST, etc. There are many types of mashups, such as consumer mashups, data mashups, and Business Mashups. The most common mashup is the consumer mashup, which are aimed at the general public. Examples include Google Maps, iGuide, and RadioClouds. 4D Wall-map display is data mashups combine similar types of media and information from multiple sources into a single representation. This technology focus data into a single presentation and allow for collaborative action among ITS-related information sources.

The semantic information provided through the semantic-based IoT system will produce new high value-added products that are completely different from what we have known and experienced. From this point of view, the key issue of current IoT technology and applications is the development of an intelligent IoT platform architecture. The proposed system collects the IoT data of the sensors from the cloud computer, converts them into RDF, and annotates them with semantics. The converted semantic data is shared and utilized through the ontology repository. We use KT's IoTMakers as a cloud computing environment, and the ontology repository uses Jena's Fuseki server to express SPARQL query results on the web using Daum Map API and Highcharts API. This gives people the opportunity to access the semantic IoT mash-up service easily and has various application possibilities.

스마트 폰 사용자 수가 2000만명 이상이 됨에 따라 모바일 맵 서비스에 대한 수요가 급증하고 있다. 한편, 모바일 기반의 맵 응용의 개발을 위해선 WINDEV Mobile 17과 같은 유료 개발 환경이 있지만 자동화 지원 경도가 미약하여 맵 응용의 생산성이 떨어지고 유지 보수 기간도 많이 소요된다. 우리가 설계하고 구현한 MobileMapGen은 GoogleMaps API를 사용하며 서버 측을 위해 CMS(Content Management System)인 Drupal 환경에 사용 가능 한 모듈들을 생성하고 클라이언트 측엔 iOS 앱을 생성해 맵 응용에 대한 생산성을 향상시켜 준다. 맵 컨텐츠와 그와 연관된 컨텐츠들을 함께 제공하는 모바일의 맵 응용 생성기인 MobileMapGen과 달리 WINDEV Mobile 17, MobilForms, 그리고 VisualStudio.NET는 맵 인터페이스를 지원하지 않거나 위치 정보 형태만을 표시한다. 그렇기 때문에 사용자가 원하는 지형/지물 컨텐츠 타입을 생성하거나 맵 상에 표시하고 관심의 대상인 지형/지물과 연관된 컨텐츠들을 검색할 수 없다.

가상 현실을 이용한 다양한 응용기술이 등장함에 따라, 그를 이용한 서비스와 상용 애플리케이션이 개발되고 있다. VR, AR 사용자가 증가하고, 주위에서도 쉽게 이러한 기술을 접할 수 있게 되었다. 이에 본 논문은 2D로 표현되는 기존의 지도 사용을 어려워하는 사람들의 문제점을 해결하기 위하여 VA과 AR-based 3D를 통합할 수 있는 지도를 연구하고 'SNUT MAP'을 개발하였다. 'SNUT MAP'을 개발하는 데 Unity 3D와 Dronedeploy, Blender, Vuforia, AR+GPS location, Google maps API를 사용하였다.

Since the mid-2000, so-called Web 2.0 paradigm was emerged and has been widely extended to actual Web markets with supporting Web technologies. Among Web 2.0 services, mashups with Open APIs is regarded as one of core technologies. Web mapping is also the most dominant mashup application in Open API-based applications, so that various mashups with Google Map API and other Open APIs are developing. In this paper, current technological status is explained with web GIS file formats of KML. While, a prototype is web-based GIS layer authoring system for general users, without any kinds of GIS tools and external spatial databases. This mashup application will be used web-based feature extraction for geo-spatial web for public users.

코로나 19로 인하여 많은 사람의 일상생활 활동량이 감소하였다. 이로 인하여 여행업계는 큰 타격을 입었다. 한국관광공사에서 실시한 '코로나19 국민 국내여행 영향조사' 응답자들에 따르면, 연간 여행횟수는 평균 6회였으나 코로나 확산이 본격화된 후, 평균 1.8회인 70% 가량 급감한 것으로 나타났다. 마찬가지로 문화체육관광부에서 실시한 '국민생활체육조사'에 따르면, 최근 5년간 증가 추세였던 생활체육 참여율이, 코로나 19의 영향으로 감소한 것으로 나타났다. 본 연구에서는 사용자가 직접 지도 위에 여행 및 운동 경로를 그릴 수 있도록 도와주고 그것을 다른 사용자와 공유하는 시스템을 개발하였다. 여행 및 운동 경로 공유 시스템을 통해 사용자들의 여행이나 운동 욕구를 증진 시키고 코로나 19로 인해, 감소한 활동량을 증가시킬 것으로 기대된다.
