  • The demand of ubiquitous home network system is rapidly increasing in Korea as each construction enterprise makes a huge effort to introduce it to apartment complex. However, the design of home network system is rather technology oriented than the customer focused. Lack of knowledge about customer needs is an obstacle in spreading the ubiquitous home network system to the market regardless of technology development. In this paper, we propose a HCSI(customer satisfaction index for home network system) using an SEM(structural equation model) where structural relationship among several factors influential on users' satisfaction is considered. This model enables to calculate the satisfaction index for target customer group so that one can provide necessary feedback information for improvement of the home network system used for each group.

  • It was only 2010 when start-up education spread to undergraduate education in South Korea. Start-up education was conducted so late that there are insufficient studies of evaluation and feedback on the effectiveness of start-up education. Education is a complex concept of teaching people in a desirable direction and developing their inherent abilities. Based on this, start-up education can be defined as cultivating students' entrepreneurial spirit internally and making them exhibit start-up competence externally by teaching them the knowledge, skills and attitudes necessary for business start-up and developing abilities such as creativity, challenge spirit and problem-solving skills. This study conducted pre and post survey to check if the education camp for the technology start-up, which is a practice-oriented start-up education, has an effect on the change of the participating students' perceptions about the business start-up. This study would analyze various factors of college students' business start-up through a factorial analysis so that the quantitative accumulation of start-up education can lead to a qualitative change and propose measures for the management of the quality of the education.

  • Capture efficiencies of commercial shrimp trawls may improve if their designs took into better account behavioral responses of wild shrimp to approaching cod-end of the trawls. Here we report results of water tunnel-based experimental studies of responses of wild California target prawns to several different near-realistic netting configurations over a range of water velocities (0.3-0.7 m/s). Netting panels were oriented at parallel to water flows (FP) on the bottom of test section, vertical (VT) or diagonal sloping backward (DG), bottom to top. Behavioral responses were recorded by video camera and analyzed frame by frame. Measured responses included rates of penetrating through netting by behavioral features and tail-flip frequencies. Frequencies of prawn passing through the nets increased with flow speed for both orientations and were higher at given speeds for sloped nets. Other behavioral features (e.g., passage head-or tail-first) also varied significantly with water velocities and netting orientation. Interactions of penetrating rates between netting orientations and flow speeds also were significantly dependent, except for prawn size. Additional studies are needed of other shrimp species and at higher water velocities more similar to actual field operations using trawls to improve size selectivity.

  • The main purpose of the present study are as follows: First, through the extensive literature review, we tried to find out environmental changes in the management thoughts. Second, as we found a new paradigm on valuation-oriented management thoughts, we argued that cost/management accounting information should play key roles in creating values. Third, we pointed out that when firms used only financial performance measurements, problems could take places. Finally, especially to promote the organizational effectiveness and efficiency, we stressed that firms should use the balanced scorecard approach in performance measurements of its own organizations and personnels.

  • Ubiquitous technology is currently being introduced to libraries at the fastest speed as compared to other spaces. However, the introduction of ubiquitous technology to the existing analog space is causing problems despite such intelligence of libraries as the design standards for ubiquitous spaces have not been arranged yet. This researcher analyzed and evaluated the characteristics of design from the ubiquitous aspect of the ubiquitous environment-oriented libraries that are still at their initial stage. The subjects for this study were the National Library of Korea, Myongji University Bangmok Library, and Yonsei University Library. The definition and characteristics of the ubiquitous environment libraries were examined through literature review and the standards for design analysis were derived by analyzing previous studies. Case analyses were conducted to evaluate the design elements in the ubiquitous environment libraries based on the field observation, photographing, and interviews with managers. As a result, functionality, safety, cognition and convenience were derived based on the investigation and analysis of previous studies; informativeness, playfulness, security, and simplicity which are the design characteristics were found. As a result of the case studies, while functionality and safety are met in most of the standards for design analysis, universality was very low. Care for minorities is need in a library as it is a space used by many unspecified individuals.

  • Subway is electrified railway system nowadays, in which liquid dielectric transformers have been widely used, though mold type transformers are replacing it. The transformers supplies large electric power and have innate hazards causing accidents under operation. A number of researcher have carried out on failures of it and have oriented to identify transformer's failure causes and how to maintain it healthy state. The transformer failures can cause serious accidents which can provoke economic loss and leads persons to kill. In this paper, we carried out a safety activity to reveal hazards and to estimate risk of subway liquid dielectric transformers using FMEA, HAZOP and What-if methods. In case of installing safety devices in oil immersed transformer, we tried to evaluate an effect on a subsystem's failure rate. We proposed how to design subsystem failure rate and safety device failure rates.

  • This paper introduces a vision-based automatic system (VAMS) for non-contact measurement of morphometric characteristics of flatfish, such as total length (TL), body width (BW), height (H), and weight (W). The H and W are simply measured by a laser displacement and a load cell, respectively. The TL and BW are measured by a proposed morphological image processing algorithm. The proposed algorithm cans measurement, when the tail of flatfish is deformed, and when it is randomly oriented. In the experiment, the average and maximum measurement errors were recorded, and standard deviations and coefficients of variation (CVs) for the measurements were calculated. From those results, when flatfish the TL measurements had an average of 266.844 mm, a standard deviation of 0.351 mm, a CV of 0.131%, and a maximum error of 0.87 mm with straightened flatfish ($TL_A$ : 267 mm, $BW_A$ : 141 mm), and when flatfish of different sizes were measured, the errors in the TL and BW measurements were both about 0.2 %. Using a single conveyor, the VAMS can process up to 900 fishes per hour. Moreover, it can measure morphometric characteristics of flatfish with a TL of up to 500 mm.

  • It was studied the effect of a pre-deposited ultrathin Al layer as part of a buffer layer for the growth of GaN. AlN buffer layers were deposited on a Si(111) substrate using an RF sputtering technique, followed by GaN using hydride vapor phase epitaxy (HVPE). Several atomic layers of Al were deposited prior to AlN sputtering and the samples were compared with the others grown without pre-deposition of Al. And it was also studied the influence of AlN buffer layer thickness on the growth of GaN. The peak wavelength of the photoluminescence (PL) was varied with increasing the thickness of the GaN and AlN layers. The optimum thickness of AlN on a Si(111) substrate with an ultrathin Al layer was about $260{\AA}$. Scanning electron microscope (SEM) images showed coalescent surface morphology and X-ray diffraction (XRD) showed a strongly oriented GaN(0002) peak.

  • Biotechnology is often described as the 'exploitation of biological processes for industrial purposes'. The last twenty years have seen phenomenal growth in this industry. The 21 century promises to see further advances in the field. However, since the cost of research is high, and the potential returns are linked to exclusivity, intellectual property protection is critical to this burgeoning industry. Without protection such investments in R&D would not be made and, the benefit that BT-related development are expected to bring, would not occur. BT industry are eager for high technology, and the technology must be transferred to a corporation from a research organization. In order to be successful, it is important that scientist must be directed toward R&D outcome beyond performance assessment. The process to gain a outcome involves multiple steps to turn the idea into the profit, and intellectual property issues are considered into the critical factors to affect the quality of R&D. The management of Intellectual property is very important in R&D. However, According to the survey conducted by KIIP (Korea Institute of Intellectual Property) and KOSEF (Korea Science and Engineering Foundation) in 2006, it is estimated the ability to treat Intellectual property is not sufficient because 82.5% of the respondents have not received an education. Governmental Support is needed to prompt systematically the ability of intellectual property management through education and consulting.
