In this paper, we designed the open service platform based on integrated type of individual customized service and intelligent information technology with individual's complex attributes and requests. First, the data collection phase is proceed quickly and accurately to repeat extraction, transformation and loading. The generated data from extraction-transformation-loading process module is stored in the distributed data system. The data analysis phase is generated a variety of patterns that used the analysis algorithm in the field. The data processing phase is used distributed parallel processing to improve performance. The data providing should operate independently on device-specific management platform. It provides a type of the Open API.

The SDR(Software Defined Radio) system for hardware and software must be an open structure to various system standards. It should also provide a capability of distributed processing, object-orientedness, and software controllability. It implies that the software to be used in the SDR system should provide the openness such that it can operate independently of a given hardware platform. In order to achieve these goals, the SDR system tends to modularization for increasing hardware reuse and design flexibility, which provides the system reconfigurability. In this paper, we implemented a base station with proposed an open architecture of a Smart Antenna Base Station(SABS) and Smart Antenna APIs[10] operating in SDR network in such a way that the architecture itself is suitable for the entire system to maintain the openness, object-orientedness, and software controllability.

국내의 미세먼지 문제가 심각해짐에 따라 대기 오염에 관한 분야의 관심이 높아지고 있다. 현재 정부는 최근 IT 융합 기술의 발전에 따라 빅데이터, 클라우드, 등 사물인터넷 기반 장치의 확산 및 고도화를 위한 기술 접목에 많은 지원과 관심을 보이며 기상청을 통해서는 국내 대기 오염으로 인한 사회적 비용을 낮추기 위해 공공 데이터(Application Program Interface, API)를 활용 다양한 정보 서비스를 지원하고 있다. 하지만 기상청에서 제공하는 정보 서비스에는 한계가 있다. 특히 기상청에서 운영되고 있는 장비들은 고가의 장비로써 비용 및 공간적 설치 제약이 따르며, 약 15km 범위를 한 개소로 담당하여 기상 데이터에 대한 신뢰도에 문제가 발생하고 있다. 본 논문에서는 오픈 하드웨어 기반 소형 기상관측 장비를 활용한 기상지수 및 미세먼지 측정 데이터 제공 시스템을 제안한다. 본 논문에서 제안한 시스템은 기상 계측이 필요한 지역의 작은 공간을 활용, 기상관측 장비를 통해 관측된 데이터와 기상청에서 제공하는 생활 기상지수 알고리즘을 토대로 해당 지역에 맞는 맞춤형 정보를 제공하여 사회적 비용을 낮출 수 있을 것으로 기대한다.

Recently, market of mobile spatial information service is increasing along with enlargement of geo-spatial information utilization area and spread of smartphone. In particular, smartphone users look forward to utilizing spatial information service more easily and conveniently. Korea has the potential for spatial information technology development, but does not have enough governmental support to develop various spatial information service in mobile network environment. Hence, it is need to make governmental support plans for utilizing mobile services and promoting the related industry base on mobile spatial information. In this paper, we propose governmental action plans for utilizing mobile services and promoting the related industry by surveying mobile application/web services and analyzing demands of mobile spatial information experts.

In recent years, social awareness and concern about the SNS is getting a lot and many researches on the social impact of the SNS and variety strategies using SNS have emerged one after another. In this paper, we explain the method of interlocking between SNS and variety sensors in physical computing environment. Especially we propose that interlocking technology between sensors and twitter in Arduino platform(open source environment) can be used for the handicapped people. We design a way to send message via twitter for handicapped people using values from various sensors.

최근 방송 통신 기술의 눈부신 발전에 힘입어 등장한 데이터 방송(Data Broadcasting)은 시청자에게 영상과 음성환 아니라 기존에는 접할 수 없었던 다양한 서비스들을 제공하고 있다. 이런 데이터 방송을 수신하기 위해서는 TS로부터 데이터를 추출하고 처리할 수 있는 미들웨어(middleware)가 포함된 셋탑박스(set-top box)가 필요하다. 그리하여 MHP, OCAP, ACAP 등 여러 데이터 방송 시스템의 미들웨어 표준 규격이 정의되었다. 그 중 MHP의 경우, OpenMHP라는 오픈 소스 프로젝트를 통해 PC 상에서 간단하게나마 MHP API를 테스트 해 볼 수 있는 환경을 제공해 주고 있다.[1] 하지만 셋탑박스 내에서 하드웨어를 이용하는 작업들은 거의 구현되지 못 했기 때문에 테스트에 있어 극히 제한적일 수밖에 없었다. 따라서 본 논문에서는 소프트웨어적으로 셋탑박스 환경을 에뮬레이션 해주는 Virtual Set-Top Box(VSTB)를 설계, 구현하였다. 셋탑박스가 없는 환경이나 간단한 시뮬레이션이 필요한 경우, 실시간 스트림 역다중화와, 파싱, 필터링 작업등이 지원되는 가상 셋탑박스 시스템을 통해 MHP 미들웨어 API를 테스트하는데 유용한 역할을 할 수 있을 것이다.

This paper proposes 3D visualization systems for the real-time situation awareness and a state information of the aircraft. This system was embodied with OpenGL and the Google Earth of web base using situation data of the aircraft. The existing system has problem which speed decrease and visible restricted map because massive data of terrain and satellite photo. This system is supports the visualization tool which is economic and entire area for a real-time situation awareness with minimum flight information using Open-API of the Google Earth. Also provides a visible convenience to expansion-view using multiple location information. This research result could be used to system for the situation awareness of the aircraft from web environment.

A core technology of social robot is voice recognition and dialogue engine technology, but too much money is needed for development and an implementation of robot's conversation function is difficult resulting from insufficiency of performance. Dialogue function's implementation between human and robot can be possible due to advance of cloud AI technology and several company's supply of their open API. In this paper, current intelligent social robot technology trend is investigated and effective social robot system architecture is designed. Also an effective analysis and design method of social robot system will be presented by showing user requirement analysis using object-oriented method, flowchart and screen design.

The accuracy of the model and the explanation of the results are important factors that should be considered simultaneously Recently, applications of explainable artificial intelligence are increasing, and it is especially widely applied in the financial field where interpretation of results is important. In this paper, we compare the performance of open API credit evaluation data using various machine learning techniques. In addition, existing financial logic is verified through explainable artificial intelligence technologies, SHAP and LIME. Accordingly, it is expected to demonstrate the applicability of machine learning in the financial market.

Recently, the VWORLD was built to ensure competition on the advance of domestic enterprise into foreign markets with rapid expansion of spatial information industry of the world. However, the policy to secure user is insufficient because the VWORLD's service is embryonic stages. Then again, tourist industry is growing rapidly and leading the world economy and number of domestic tourists are also steadily increasing. Although the size was expanded, Korean tourist industry's competition is relatively weak, so some scholars insist that raising the tourist industry's quality. This backgrounds make a study of the tourism information service. So, this paper progressed a study on the development of the tourism information service based on a service science and used VWORLD as a test model. This paper drew the customer's demands on the tourism information service and strategic points of the development from those by using a Quality Function of Deployment of service science's new service development methodologies. After that this study prioritized those strategic points. As a result, 'Face Map' that is a service model was made. Moreover, this study have try to raise the development's effectiveness and efficiency based on service science's a new service development process.
