The study aims at suggesting the direction of industrial utilization for harmful jellyfish which appears in large quantities in the Korean coastal areas. If the technology of industrial utilization for the jellyfish is developed, it will be possible to grow the industry to the export industry due to the mass appearance of jellyfish in Korean coastal areas. The industrial utilization of jellyfish should follow the direction of minimizing the damage by the jellyfish blooms and maximizing the resource recycling of the jellyfish. Therefore, Korea needs construction of infrastructure for the industrialization and promotion of R&D in order to activate the industrial utilization. Finally, the study suggested issues and tasks for promoting the industrial utilization of jellyfish as follows. First, Korea should stabilize the high quality raw material supply system. Second, mass processing technology should be developed for the industrial utilization of the jellyfish. Third, research and manual development should follow for the preparation of turning the jellyfish to the food. Fourth, extraction technology of useful non-food substance such as extracting collagen from jellyfish should be developed and accelerate the industrial utilization of non-food area.

It has been a major issue to repair the broken system quickly for improvement of productivity and utilization. Generally, high utilization of system requires the high amount of spare parts in inventory and inventory cost. Therefore, it is necessary to determine the proper amount of inventory with regard to utilization of system. This study designs a methodology for determining the proper amount of inventory level in a two-echelon spare parts distribution system. The requirements are to satisfy proper customer demands at a distribution center and to maintain over the utilization of the whole system at customers. This methodology minimizes total inventory investment at a distribution center and customers.

As the development of artificial intelligence (AI) technology spreads to various industrial sectors, diversity in AI utilization rapidly increases, creating rich user experience. In addition, AI is required to solve various social problems through the use of public data. The spread of AI utilization across all sectors will continue, covering such industrial and public demands. This article examines the domestic and international trends in AI utilization technologies and establishes the direction of research and development (R&D), which is highly consistent with Korea's AI policy. ETRI, which leads AI's national R&D, has used its experience to establish AI R&D implementation strategies as well as technology roadmaps for the utilization of AI to improve individual quality of life, continuous growth in society, industrial innovation, and the solutions to public societal problems. In addition, it has derived tasks and implementation strategies for developing AI utilization technologies in 10 major areas including medical services.

This paper presents the performance characteristics of a 1 kW solid oxide fuel cell (SOFC) stack under various internal reforming and fuel utilization conditions. The Research Institute of Industrial Science & Technology (RIST) developed the 9-cell stack using a $20{\times}20cm^2$ anode supported planar cell with an active area of $324cm^2$. In this work, current-voltage characteristic test, fuel utilization test, continuous operation, and internal reforming test were carried out sequentially for 765 hours at a furnace temperature of $700^{\circ}C$. The influence of fuel utilization and internal reforming on the stack performance was analyzed. When the 1 kW stack was tested at a current of 145.8 A with a corresponding fuel utilization of 50-70% (internal reforming of 50%) and air utilization of 27%, the stack power was approximately 1.062-1.079 kW. Under continuous operation conditions, performance degradation rate was 2.16%/kh for 664 hours. The internal reforming characteristics of the stack were measured at a current of 145.8. A with a corresponding fuel utilization of 60-75%(internal reforming of 50-80%) and air utilization of 27%. As fuel utilization and internal reforming ratio increased, the stack power was decreased. The stack power change due to the internal reforming ratio difference was decreased with increasing fuel utilization.

The founding purpose of Business Incubation System is to induce those businessmen who have technology and promising business ideas but are lacking fund, information, and management skill, and to speed up their business establishment and enhance the level of success by providing them with managerial knowledge, production technology, design, and equipment. While some universities made Business Incubation Center to achieve the above purpose, some other universities, especially the local ones, believed that Business Incubation Center, if managed successfully, could be an accelerator picking up the sluggish local economies. This study studied the motivators that let them move in an Incubating Center, their request for support, their level of expert utilization, and the role of head of a Center. This study found a significant level of correlation among the variables such as industrial-educational cooperation, the development of common items, utilization of professors with matching majors, utilization of research professors, and transfer of technology.

표준은 산업발전 및 무역 자유화의 기반이며 사회 경제적인 효율을 향상시키는 중요한 수단이다. 표준과 관련된 정책은 국가적인 차원에서 중요한 이슈 중 하나가 되고 있으며, 이에 따라 산업 분야별 한국산업표준 제정과 활용에 대한 분석은 표준과 관련된 연구에서 중요한 부분이 되고 있다. 본 연구는 분야별 KS 보유 및 제정현황 분석 그리고 열람실적을 이용하여 표준의 활용도를 분석한다. 먼저 KS의 보유현황을 국가정책적인 이슈와 함께 살펴보고, 세부적으로 KS 제정현황이 유사한 분야들은 무엇인지 파악하기 위해 다차원 척도법을 이용하여 시각화 및 군집화를 실시한다. 이후 각 군집별 제정현황이 유사한 분야들의 표준화 제정활동에 영향을 미치는 결정요인이 무엇인지 가설설정에 따른 회귀분석을 실시한다. 연구결과 자본집약도, 연구개발 그리고 매출액이 표준화 제정활동에 영향을 미치는 것으로 나타났다. 이에 따라 정부는 자본집약도가 큰 기업들이 표준화 과정에서 선도적 역할을 유도하고, 연구개발에 따른 표준과 기술특허 등을 정책적으로 연계시키며, 매출액이 큰 기업들이 표준화 활동을 선도하도록 지원정책을 수립해야 한다. 두 번째로 표준의 활용도를 분석하기 위해, KS 열람실적 데이터를 사용하며, 각 KS의 제정연도, 형태 분야별 활용도가 어떻게 다른지 기초통계분석과 의사결정나무를 사용하여 분석을 수행한다. 그 결과 표준의 제정시기가 활용도에 영향을 크게 미치며, 특정 분야와 형태의 KS들은 최근에 제정되었더라도 활용도가 높은 것으로 나타났다. 이에 따라 열람실적이 낮은 표준들에 대한 홍보 정책과 함께, 표준을 제정할 때 미열람되는 표준이 적어지도록 활용도를 고려하는 정책을 수립해야 한다.

This study focuses on the necessity of MOT methods in companies, especially the utilization level. Based on the analysis structure of the previous study (2012), this study was conducted to compare the results with the previous results. We investigated the settlement level of MOT, the degree of necessity for MOT methods, the degree of actual use, and the Product Realization Process (PRP) for MOT-related researchers in electronic companies (n=184). It was confirmed that the higher the demand for MOT methods in the corporate field, the higher the utilization level (ratio). In particular, the need for and utilization of techniques such as Environmental Analysis, Business Opportunity Analysis, Project Feasibility Review, Roadmap, Risk Management was high. These methods were beneficial along with cost management and quality management techniques. The most challenging part of using MOT methods was the lack of systematic use, the absence of experts, and the difficulty in selecting suitable techniques. The necessity of opening subjects such as Creative Thinking, Communication, Teamwork, and Professional Ethics was high among the PRP subjects. Furthermore, the necessity of opening courses in Cost and Safety Design and Applied Statistics was higher than in the previous study.

Automated Guided Vehicles are widely used as an essential material handling system for FMS to provide flexibility and efficiency. We suggest a new dispatching rule based on priority function which considers urgency and empty vehicle travel time under finite buffer capacity. We evaluate the performance of the proposed rule by comparing the performance of Shortest Travel Time/Distance(STT/D) rule in terms of machine utilization, throughput and WIP level using simulation. The simulation results show that the suggested dispatching rule is robust and provides better machine utilization, throughput with comparable WIP level compared to STT/D rule.
