  • The purpose of this study is to conduct Project Based Learning (PBL) in collaboration with industry experts to operate practical subjects in an industry-university-linked teaching method. PBL is a teaching method in which students can learn through actively engaging in real-world and personally meaningful projects. For a long period of time, PBL methodologies have been found to be especially effective in engineering education. This case study deals with the operational results of a practice subject which has been conducted over three years from 2017 to 2019 in Korea University of Technology and Education. The course is for the 4th grade students in the school of mechatronics engineering. The results of the surveyed learning outcomes (for example, Program Outcomes and Course Learning Outcomes) have been analyzed and reflected in the next years for the Continuous Quality Improvement. By working on practical projects linked to industry, students have been able to develop so-called 4C's capabilities which are Critical Thinking, Creativity, Communication and Collaboration.

  • As Information Technology (IT) is developed constantly, big data is becoming important in various industries, including ship and offshore industry where a lot of data are being generated. However, it is difficult to apply big data to ship and offshore industry because there is no generalized platform for its application. Therefore, this study presents a big data platform based on the Hadoop for applications in ship and offshore industry. The Hadoop is one of the most popular big data technologies. The presented platform includes existing data of shipyard and is possible to manage and process the data. To check the applicability of the platform, it is applied to estimate the weight of offshore plant topsides. The result shows that the platform can be one of alternatives to use effectively big data in ship and offshore industry.

  • The engineering knowledge and technology is core driving forces of continuous growth in knowledge based society. Companies, the government, and universities are the subjects of an innovation and the cooperation between them is very important. Nowadays, the main purpose of industry-university cooperation moves to train experts and develop a new product. A shift of the paradigm came from the change of recognition that the final consumers of the program are companies and the universities are supporters of the program. In this paper, we investigate the purpose, participation and satisfaction of companies to industry-academy technology cooperation through empirical studies. The need to expert training, product development and process development makes companies participate industry-academy technology cooperation and companies have different purpose of participation by the business type. Companies often feel that expert training, subsidiary purpose of industry-academy technology cooperation, is more important than product development or process development. This result is caused by the real world environment of small and mid-size companies, lacking of technology experts. The participation of companies to each technology cooperation program (technology transfer, joint technology development, consigned technology development, technology consulting, co-op. lab.) is also different by business type. The companies' satisfaction with the purpose of process development is relatively higher than that with the purpose of product development and companies show also different satisfaction value by business type and participating program. The results of this study can give a contribution to the design of demand oriented industry-academy technology cooperation model.

  • Bacterial cellulose (BC) is generated from citrus gel by Gluconacetobacter hansenii TL-2C. BC has good properties such as high-burst pressure, high-water contact and the ultrafine highly nanofibrous structure of mimic natural extracellular matrix (ECM) for tissue engineering. In this study, acrylic acid (AAc) was grafted onto BC surfaces under aqueous conditions using gamma-ray irradiation, and then immobilized gelatin onto AAc-g-BC. The characterization of scaffolds was performed by scanning electron microscopy (SEM), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), toluidine blue O (TBO) assay. Morphology of gelatin and AAc incorporation onto BC nanofibers did not changed. Our study suggests that gelatin-immobilized BC nanofibers scaffold has a potentiality to fabricate 3D nanofibrous scaffolds for tissue engineering.

  • Cities in Indonesia include diverse scattered industrial centers comprising industries that can sustain the existing economic pace. For industrial data collection, the city government still relies on census that consumes extensive time and money. The public are unfamiliar with industries owing to their lack of industry information; therefore, the market share is not optimal. In addition, the opportunity to procure investors for business development is limited. A Geographic Information System (GIS) is a computer system that can record, store, write, analyze, and display geographical data. Using the Rapid Application Development (RAD) method, GIS was developed on a website platform to provide information on industry profiles, types of production, investment values, industry maps, and industrial locations in each village and sub-district to a wider community. The RAD method was chosen compared to the waterfall method because it could accelerate website development process.

  • Remanufacturing is an industrial manufacturing process. The merits of remanufacturing are to reuse old products to perform like a new product and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. This paper proposes a systemic approach for activating the domestic remanufacturing industry. The approach is based on inside and outside regulations to apply remanufacturing companies. And, we analyzed the state and problems of remanufacturing industry for automobile parts. Also 5 essential tactics and 20 detail strategies are suggested. On the basis of the approach, the domestic remanufacturing industry will carry out the cooperation for their competitions.

  • Foam reaction injection molding (FRIM) is a widely used process for manufacturing polyurethane foam with complex shapes. Numerical model for polyurethane foam forming reaction during FRIM process has been intensively investigated by a number of researchers to precisely predict final shapes of polyurethane foams. In this study, we have identified a problem related with a previous theoretical model for polyurethane foam forming reaction. Thus, previous theoretical model was modified based on experimental and computational results.
