Smart Connectivity를 위한 IoT, 네트워킹, 보안 솔루션을 제공하는 (주)브로드웨이브는 자사만의 경쟁력을 통해 벤처기업 인증, 이노비즈기업 인증, 기업부설연구소 설립 등 내실있는 기업으로 발돋움하고 있다. 특히, 개방과 공유로써 성공적인 IoT 비즈니스를 만들기 위해 국제 표준 기반의 개방형 IoT 서비스 개발에 주력하고 있다. 이의 일환으로, 사용하지 않는 중고 스마트폰을 활용하여 IoT 표준화를 통해 다른 스마트폰이나 PC, 노트북 간의 게이트웨이로서 기능케 하는 기술을 개발 중이다. 이를 위해서는 많은 전문가로부터 다양한 관점을 전달받는 것이 중요했고, 고민 끝에 TIA의 중소 중견기업을 위한 표준 자문서비스의 도움을 청하게 되었다.

ICT 기술의 발달과 농촌의 고령화로 인한 사회적 문제(노동력 부족)를 해결하기 위하여 스마트팜(Smart-Farm) 상품이 많이 운용되고 있다. 하지만, 대부분의 스마트팜 솔루션은 통신기술을 기반으로 개발 및 상품화되었다. 따라서, 시설재배 농가의 요구사항(일관된 생산품질 유지 및 돌발상황 대처 등)이 반영된 스마트팜 상품을 개발하기 위한 제품과는 거리가 멀다. 본 연구에서는 IoT 플랫폼 기반의 시설재배용 스마트 관제시스템 최적화 모델을 개발을 위한 설계 결과를 제시하고자 한다.

(주)피제이팩토리는 이미지의 정보화 작업을 최소한의 움직임으로 가능하게 하는 UX(User eXperience)를 개발했으며 관련 특허를 보유하고 있다. '디테일(Detail)'은 그 특허를 통해 구현된 (주)피제이팩토리의 모바일기기 기반 카메라 앱 및 SNS 서비스다. 2016년 2월, 기업환경통합(EAI/E5B), 애플리케이션성능관리(APM) 및 보안 솔루션 개발 구축 전문업체인 모코엠시스로부터 5억여 원의 투자를 유치했다. 새로운 이미지 파일포맷을 개발하던 (주)피제이팩토리는 국제 표준화의 필요성을 알았으나, 구체적인 진행 방법과 전략을 구상하기에는 정보와 경험이 턱없이 부족했다. 이때 지인의 소개로 국제 표준화 작업 과정을 도울 기관으로 TTA를 추천받았다. TTA의 자문서비스를 통해 국제표준화기구인 ISO/IEC JTC 1 SC29에 국제 표준으로 제안할 구체적인 전략을 세우게 되었다.

The purpose of this study is to present a block type smart classroom model for comprehensive supply of educational contents, classroom environment and ICT technology in African countries where educational infrastructure is weak. It will provide a contextual solution that integrates learning management, power management, and classroom environment management systems, and will be a convergence model that can optimize economic and non-economic conditions for different African countries. It can be expected to enhance utilization as it is a differentiated model from existing classrooms with a single container, as well as independent research and development centered on services, content, and solutions. Through this integrated research process, we can overcome the spatial and functional limitations appearing in single container classrooms and build a flexible space for advanced e-learning technology. The depth and scope of the follow-up study can be carried by investigating the performance and models that are in line with the educational and infrastructure conditions of the various regions.

Recently, ASEAN is not only a new production base but also a consumer market for Korea, and interest in the utilization of production networks in each region is increasing. In particular, urbanization in ASEAN countries is progressing at a relatively fast pace. Each country is promoting smart city projects combined with ICT to improve outdated basic infrastructure facilities such as housing, transportation, logistics, crime prevention, and disaster prevention. The purpose of this study is to develop a web-based smart city export HUB platform so that companies with excellent domestic smart city solutions can participate in smart city construction through networks with ASEAN countries. These platforms can secure the demand for smart city construction in ASEAN countries, and through the establishment of the Korea-ASEAN public-private network, smart cities planned in ASEAN countries can be promoted more innovative. In addition, it is expected to be positioned as a Global smart city platform model by applying to real cities through collaboration with excellent domestic companies.

This study presented the factor analysis on constructing the new factors affecting the middle school students' online learning behaviors from the questionnaires employed among middle school students. A total of 204 students participated and the data were collected in South Korea. The sample of middle school ninth-grade students was selected and used through purposive sampling. Findings from the factor analysis provided evidence for the eight-factor solution for the 35-items accounting for 66.15% of the shared variance. A wide range of factors has been considered to identify students' online learning behaviors. The appropriate experience and use of e-learning in the middle school period is also important as it will be a critical stepstone for future education. This research provides information that has been taken into account for advancing online learning to enhance the quality of e-learning systems for middle school students. The study results provided eight new factors affecting the middle school students' online learning behaviors; that is 1) communication using social media as a learning tool, 2) intention to share information using ICT, 3) addiction of technology, 4) adoption of technology, 5) seeking information using ICT, 6) use of social media learning, 7) information search using ICT, and 8) immersion of technology. This study confirmed that middle school students prefer communication using social media as a learning tool, and value intention to share information using ICT for the most part. The data obtained based on factor analysis can highlight the online learning behaviors towards a mixture of social media learning and ICT to ensure a new educational platform for the future of e-learning. This research expects to be useful for both middle schools of online learning to better understand students' online learning behaviors and design online learning environments and information professionals to better assist students who particularly need digital literacy.

Information and Communication Technology (ICT) remote soil moisture control system including soil sensing, automatic water supply chain, and remote alarming system was established on reclaimed land and operated stably. The system was operated using river water around the reclaimed land without fertilizer. On applying this system to control soil moisture, the kenaf germination rate was improved up to two times. Kenaf biomass was 4,748 kg/10a and was higher than that of untreated soil moisture management. When the nutritious liquid fertilizer was used, kenaf yield reached 8,390 kg/10a, which was lower than 10,848 kg/10a of the non-reclaimed land treated with standard chemical fertilizers. As the soil moisture was managed stably through the ICT remote soil moisture control system, the quality of the kenaf crop was improved, resulting in a 7% increase in dry weight, and a 11.5% increase in plant hardness. The estimated kenaf yield was 5,039 kg/10a when 800 tonnes of water were supplied by the ICT remote soil moisture control system with the stream water around Saemangeum reclaimed land without chemical fertilizers and organic matter.

Recently, interest in blockchain technology has increased. The data industry is increasingly growing around the world. In addition, databases which obtain important information such as personal data are targeted by hackers. Data exposed by attackers happen frequently. In 2017, OWASP announced SQL injection is a top 1 threat to web applications. However, the proportion of data security is the smallest in the data industry. To prevent data exposure, this paper proposes a method that can protect databases by using hybrid blockchain.
