2018년 현재 한국과학기술정보연구원(KISTI)은 계산과학공학 플랫폼 기반으로 온라인 시뮬레이션이 가능한 EDISON(EDucation-research Integration through Simulation On the Net) 서비스를 제공하고 있다. 해당 플랫폼 서비스는 7개 전문분야(전산의학, 전산설계, 전산열유체, 구조동역학, 계산화학, 나노물리, 도시환경)의 학생 및 연구자들이 학습 및 시뮬레이션을 실행하고 결과를 활용할 수 있도록 지원하고 있다. 하지만 EDISON 플랫폼은 시뮬레이션 서비스에 초점을 맞춰 개발과 서비스를 제공했기 때문에 국내외 MOOC(Massive Open Online Course) 서비스들에 비해 아직 교육 콘텐츠가 부족하다. 그리하여 본 논문에서는 계산과학공학 플랫폼에 교육 콘텐츠를 체계적으로 제공하기 위한 커리큘럼 서비스를 설계 및 제안하였다.

In this paper, a design and implementation for direct deal distribution platform is proposed to bypass the complex traditional distribution structure of agricultural market, as one of the fields where distribution patterns have changed. In the case of domestic agricultural distribution, demand and supply are unstable since the sales market is excessively concentrated in the designated wholesale market. Besides sales must go through multiple stages of distribution leading to problems in freshness and stability of agricultural products and downward pressure on profit margins for producers. To solve the above mentioned issues, we propose a cloud service convergence direct deal distribution platform based on asynchronous-driven Node.js. The proposed platform can facilitate a variety of direct trading functions and also access to visualization information related to agricultural products, which may increase user confidence at an intermediary-free direct transactions platform. First, we describe the requirements of intermediary-free direct transactions of agricultural products and transaction entities. Next the database structure and transaction functions are designed and then implemented according to those requirements. Finally, an API based cloud convergence service structure is designed to provide the analyzed information to ensure a trustworthy system.

Purpose Even if many startups firms have developed innovative items and a potential for success, they often have a limited financial resources, which makes them difficult to do business. To overcome this financial difficulty, startups have used one of fintech services, called crowdfunding that can be a good alternative to solving the difficulty of financing. The purpose of this study is to empirically validate the proposed research model that investigates the reasons of trusting crowdfunding platform, which positively leads to two outcomes - intention to participate and word-of-mouth for reward-based crowdfunding project. Design/methodology/approach We proposed several factors categorized as trust, information quality, and platform traits that have a positive impact on trust of crowdfunding platform, which positively leads to intention to participate and word-of-mouth of crowdfunding. The collected(n=285) from individuals who have participated in crowdfunding project was analyzed with SmartPLS 3.0 to test proposed hypotheses. Findings The results showed that all proposed variables (website reputation, crowdfunding familiarity, digital storytelling, information quality, and interaction) had a significant impact on crowfunding platform trust with exception of product differentiation. In addition, crowfunding platform trust was positively associated with participating intention and word-of-mouth. Based on findings, we discussed the research results and implication alone with a direction for future studies.

Purpose - In the 21st century, as information technology advances alongside the emergence of the 4th generation, industrial age, industrial environment has become individualized and customized. It is important to hire good quality employees for good service in the industry. The e-learning market is growing every year. Although e-learning companies are finding better quality employees in e-learning, it is not easy to find it. Companies also spend a lot of time and cost to find employee. On the employees side, they want to get a job freely when they want, but they cannot find their job easily. Furthermore, the labor market environment is changing fast. In the 4th generation, industrial age, employers require to find manpower whenever they need and want at little cost. So of their own accord, we have considered the necessity of management of human resources for employees and employers in e-learning. The purpose of this study is to propose a human cloud platform framework for enabling an efficient management of human resources in e-learning industry. Research design, data, and methodology - To pinpoint the items of a human cloud platform framework, the study was initiated according to the following process. First, items of competency relating to e-learning instructional designer was analyzed. Second, based on the items of information from this analysis, selection and validity verification took place with 5 e-learning specialists group. Third, the opinion of experts who were in charge of hiring in e-learning companies were collated with the questionnaire. Lastly, the human cloud platform framework was proposed based on opinion results. Results - The framework was comprised of 7 domains and 27 items in order to develop the human cloud platform for e-learning instructional designer. The analysis results showed that the most highly considered item were 'skill (4.60)' that employee already have the capability. Following this (in order) were 'project type (4.56)', 'work competency (4.56)', and 'strength area of instructional design (4.52)'. Conclusions - The 27 items in the human cloud platform framework were suggested in this study. Following this, we can consider to develop the human cloud platform for finding a job and hiring e-learning instructional designer easily. For successful platform operation, we need to consider reliability between employer and employee. In addition, we need quality assurance system based on operation has public confidence.

이 연구는 선박금융산업에 블록체인기술을 적용한 STO(Security Token Offering) 플랫폼 구축으로 민간 선박금융 생태계를 활성화하는 데 대한 연구이다. 국내 민간선박금융 생태계는 자본시장법과 선박투자회사법에 근거해 형성되었으나 장기간의 해운 불황으로 주로 정책금융에 의존하게 되어 민간의 참여 확대가 지속적으로 강조되었다. 이 논문에서는 국내 선박금융에 대한 블록체인 STO(증권토큰화) 적용을 통해 민간참여가 촉진될 수 있음을 제시한다. STO 플랫폼 적용으로 네트워크 효과에 기반해 국내 선박금융 생태계가 금융플랫폼 생태계로 혁신될 수 있으며, 이에 따라 다양한 토큰발행자와 민간투자자의 참여증대를 기대할 수 있다. STO 플랫폼 설계를 위해 우선 경제-기술 통합 플랫폼 이론에 따라 플랫폼 디자인을 위한 핵심 원칙을 도출했다. 나아가 핵심원칙을 적용해 선박금융 플랫폼 설립을 위한 설계 원칙을 제시하며, 국내 선박금융 생태계를 감안한 설계방안을 제시한다. 선박금융 STO 금융플랫폼 구축효과로 1) 선박금융 참여 소비자 풀(pool) 확대, 2) 금융 참여자 간 거래 활성화를 통한 가치창출, 3) 보완적 혁신을 통한 다양한 파생상품 생성을 논의했다. 이러한 효과는 선박금융 매력도 제고, 해운산업, 조선산업 등 생태계 혁신 효과로 이어지며, 해양금융중심지인 부산금융중심지의 발전에도 공헌할 수 있음을 기술하였다.

In this paper, we describe the development of a platform-based SoC of a 32-bit smart card. The smart card uses a 32-bit microprocessor for high performance and two cryptographic processors for high security. It supports both contact and contactless interfaces, which comply with ISO/IEC 7816 and 14496 Type B. It has a Java Card OS to support multiple applications. We modeled smart card readers with a foreign language interface for efficient verification of the smart card SoC. The SoC was implemented using 0.25 ${\mu}m$ technology. To reduce the power consumption of the smart card SoC, we applied power optimization techniques, including clock gating. Experimental results show that the power consumption of the RSA and ECC cryptographic processors can be reduced by 32% and 62%, respectively, without increasing the area.

This paper presents an intuitive and powerful way to study and design motor drive control. The control of induction motors, as most widely used machines, is discussed. Thanks to ultra low latency and high fidelity Hardware-in-the-Loop systems, different aspects of up-to-date drive regulation are examined. A power stage, comprised of a grid voltage source, a rectifier, a VSC inverter and an induction motor, is emulated on the HIL platform in real time. A digital signal controller is plugged into the interface board and connected to the HIL emulation platform, without any hardware modifications. For motor control and power electronics applications, a dedicated Texas Instruments TMS320F2808 DSP is chosen. The same controller can drive an emulation platform and a real device with no modifications. Current and speed control loop test results are presented and discussed.
