A rapid growth of IT convergence into different application areas draws a lot of interest in high performance platform and embedded system. Industry needs well educated computer professionals with the practical understanding on the emerging technologies and core issues of contemporary popular services. In this paper, we present an education framework for computer system architecture based on rigorous analyses of the characteristics of IT convergence services and information technology trends. The proposed framework puts emphasis on real-world and hands-on subjects related to multicore architecture, embedded system and parallel processing. We believe effective use in the development and management of computer system architecture courses encouraging both industries and students.

This study was conducted to identify the contents of major consulting needs of SMEs using Big Data and to suggest the efficiency of operation. The subjects of the study were counseling cases posted on the website of the Business Support Center of the Ministry of SMEs and Startups. To do this, from 2009 to March 2018, we crawled about 7,000 cases of counseling cases, followed by word cloud analysis centering on effective keyword. The main results were as follows: First, the frequency of counseling cases in each field was found in the order of establishment, management strategy, human resources, financial order. Second, in word cloud analysis, the most frequent keyword related to counseling demand were small businesses, exports, methods, procedures, registration and authentication. In this study, we obtained research results that we can improve the efficiency of the policy in real time from a new point of view by conducting big data analysis on public policy.

Information inequality has been differently conceptualized and defined in national laws. While the information inequality increases, library policy and informational service has lagged behind in meeting the needs of the society and the state. This paper aims to provide a preliminary research on information inequality, in terms of conceptualization, the legal base, terminology, index development based on the level of digital information. The paper also highlights cases on library services for solution of the difference. It compares library services designed for the disabled, ethnic minorities and the aged. The paper reviews the existing literature and project data. As a result, there are a number of processes and tasks that needs to be developed, including policy development, supporting organization, human capital, cooperating network, supporting facilities and service, and data.

하천의 수위와 유량 등의 수리량 자료는 치수, 이수, 환경 등에 관한 하천 계획과 관리의 기초자료로 활용된다. 따라서 체계적인 하천 관리를 위해서는 신뢰성 있는 하천 수리량 자료의 확보가 요구된다. 이에 따라 우리나라에서는 많은 하천에 수위 관측소를 설치하여 실시간 수위를 측정하고 있다. 하지만 유량의 측정은 국가하천 등 주요 대규모 하천에 국한되어 있는 실정이다. 반면에 우리나라 대부분의 홍수 피해는 중 소하천에서 발생하고 있지만, 중 소하천에 대한 수문조사는 상대적으로 매우 미진한 실정이다. 이러한 중 소하천에 대한 수리 정보 조사의 가장 큰 어려움은 대부분의 중 소하천이 지방자치단체에서 관리하고 있어 예산과 인력 지원이 어렵기 때문이다. 이에 본 연구에서는 중 소하천에 산재한 보와 같은 하천 횡단 구조물의 유량 측정 기능을 이용하고, 급성장하고 있는 영상 분석 기술과 IT를 하천공학 분야에 접목하여 중 소하천의 수리 정보를 저비용, 실시간으로 원격 측정하는 시스템을 개발하고자 하였다. 이를 위해 연구에서는 저가형 영상 장비를 이용하여 하천 횡단구조물 주변의 흐름 영상을 원격으로 확보하고, 해당 영상을 데이터베이스로 송신하는 장치인 WIA 시스템(wireless image acquisition system)을 개발하였다. 그리고 촬영된 영상을 분석하여 수위를 도출하는 영상 분석 프로그램, 수위-유량 관계 곡선(rating curve), 미계측 지점에 대한 하천 수리 정보를 계산하기 위한 HEC-RAS를 포함하는 River-HQ 시스템을 개발하였다. 개발된 WIA & River-HQ 시스템은 한국건설기술연구원 하천실험센터 내 직선 수로(실규모 하천) 구간에 대하여 정확성이 검증되었다. 이러한 WIA & River-HQ 시스템은 실제 하천에 대한 적용성과 안정성 검토를 통해 향후 중 소하천의 환경 관리와 홍수예경보 업무 등에 활용될 수 있을 것으로 판단된다.

The competition for standardization in the enterprise environment starts with the data tier of the back-end and the standard enterprise middle tier is being stabilized by standardization as it is accepted as the Spring Framework. In addition, with the advent of new devices in an increasingly rapid cycle, securing compatibility with web and mobile services has become an important competitive advantage for web service companies. However, companies are unable to secure competent technical personnel appropriate for the rapidly changing environment of the information generation, and the curriculum of educational universities does not reflect the demand of new competency-oriented curriculum. Therefore, in this study, in order to acquire competency-oriented skills required for such an enterprise system platform environment and to develop a curriculum, the system using Spring Data JPA in the Spring Framework environment was implemented through documenting for each analysis and design step. It aims to provide a reference model for the full stack competency-based curriculum and capstone design curriculum that can be applied immediately in the enterprise environment.

This paper examines the complexity of recent SW development such as the 4th industry to apply the requirement engineering and redimimn application to the project to solve the difficulty of scope management during project management of medium and small businesses. These engineering techniques were applied to mid-sized and small-sized SW development projects. It was verified through supervision of 15 SW development projects. As a result, we observed about 30% reduction in related issues. In addition, Redmimn was introduced to SW development projects involving medium and small sized companies, and it proved that it has the effect of shortening delivery time through requirement management and tracking management. In order to secure the safety of the SW system development project, it is necessary to apply the required engineering techniques and tools, and it is necessary to continuously cultivate professional manpower to carry out this.

With the low birth rate and the inner city decline, the number of small schools is expected to increase. In this trend, the Ministry of Education has consistently used the number of students as a standard for the merger and abolition of schools since 1982, but it seems that has generated a vicious circle of education in rural areas and also it did not reflect realistic requirements and changes in the times although it is efficiency of local education finances. With the number of students constantly decreasing, it has a high probability to make villages without schools in urban areas if decisions are made by the number of students. In this sense, it is suggested that regional contexts and socioeconomic environment should be taken into account rather than to conduct the merger and abolition of small schools with economic logic. It is necessary to change the direction of improving the quality of education through the operation of small schools for coexistence of schools and villages and a cultivating the manpower needed in the 21st century knowledge information society and the 4th industrial revolution era. Therefore, we tried to find tasks for expanding small schools of the local community and developing small schools suitable for future social change.

Conventional crack detection methods have a problem of consuming a lot of labor, time and cost. To solve these problems, an automatic detection system is needed to detect cracks in images obtained by using vehicles or UAVs(unmanned aerial vehicles). In this paper, we have studied road crack detection with unmanned aerial photographs. Aerial images are generated through preprocessing and labeling to generate morphological information data sets of cracks. The generated data set was applied to the mask R-CNN model to obtain a new model in which various crack information was learned. Experimental results show that the cracks in the proposed aerial image were detected with an accuracy of 73.5% and some of them were predicted in a certain type of crack region.

최근 4차 산업혁명 시대 도래에 따른 빅데이터가 이슈화 되고 정부의 공공 데이터 개방? 공유 정책 등으로 정부의 R&D 정보화 서비스도 다양화되고 있다. 특히 해양수산 R&D사업은 해양이라는 공간적 제약으로 선박 및 특수 장비 등을 사용함에 따라 연구비 단가가 상대적으로 높은 실정임에도 해양수산 연구 자료 및 관측자료가 통합적으로 관리되지 않고, 사업별 기관별로 산발적으로 관리되고 있어, 이에 따라 연구 DB 통합관리의 수요가 제기 되고 있다. 이에 해양수산 R&D사업에서는 사업별 통합 DB 구축사업이 진행되고 있고, '관할해역해양정보 공동활용시스템(JOISS)'이 대표적이라 할 수 있다. JOISS는 2012년부터 시작된 '관할해역 해양정보 공동활용체계 구축'과제를 통해 자료 표준화 연구와 함께 해양과학조사 분야의 R&D과제들과 실시간 해양관측망으로부터 산출되는 데이터를 수집하고, 정보서비스를 구현한 시스템이다. 2016년 1차 시스템 구축을 완료하여 현재 서비스를 진행하고 있다. 한편, 해양관측 데이터 수집 공유 서비스 외 해양수산 R&D사업과 연계된 다양한 정보들을 나누고 소통하는 온라인 장을 구현하기 위해 '해양수산 R&D 지식정보 시스템(OFRIS)' 개발사업이 별도로 진행되고 있다. OFRIS는 해양수산 R&D사업을 통한 데이터의 원할한 수집 및 품질관리 등의 문제를 보완하고, 그 외에도 사업별로 분산 관리되고 있는 R&D 관련 정보를 연계하고, 기술공급자와 수요자를 직접 연결해 주는 '개방형 기술 정보 중개 시스템'으로의 역할, 국내외 해양수산 R&D관련 정책 연구 산업 동향을 엄선하여 제공하는 등 해양수산 R&D 종합 포털로서 기능구현을 목표하고 있다. 2017년 말 1단계 개발 완료를 앞두고 있으며, 1단계에서는 시급성 높고, 수요가 많은 (1) R&D동향, (2) 과제이력, (3) 연구성과, (4) 기술거래, (5) DB공유 등 5대 기능을 우선 구현하고, 2단계에서는 통계자료 생산 및 분석 기능 강화, 3단계에서는 해양수산 산업통계, 인력, 교육 등의 정보를 서비스하는 포털로 확장할 계획이다. JOISS, OFRIS를 개발하는 과정에서는 해양수산 R&D의 정보를 수집 관리 하는데 있어 다양한 현안 문제 등이 도출되었으며, 그 중에서도 연구자들의 자발적 데이터 제공 협조, 데이터의 표준화 및 품질검증, 구축된 데이터의 활용 및 피드백 등에 대해 구체적이고 현실적인 대응 방안이 요구된다.
