  • The effect of germination on hydration and germination properties, and on the changes of fatty acids and amino acids profiles of a brown rice 'Keunnun' (KN) with a large embryo was compared to 'Ilpumbyeo' (IP) with a normal embryo. A rapid germination up to 24 hr was observed in both brown rice cultivars, afterward decreased with germination time. At 60 hr, the KN ($86.0{\pm}4.24%$) showed slightly lower germination capability than the IP ($97.0{\pm}1.41%$). Lower water uptake during germination was also found in the KN ($1.22{\pm}0.02\;g$) compared to the IP ($1.59{\pm}0.05\;g$). Major fatty acids were palmitic acid, oleic acid, and linoleic acid accounting for more than 95% of total fatty acids. The most abundant amino acid in both types was oleic acid, which was decreased during germination, whereas palmitic and linoleic acids were increased. Eight amino acids were detected, and a remarkable increase in ${\gamma}-amino$ butyric acid (GABA) during germination was observed. The KN was characterized with higher tasty amino acids of aspartic acid, glutamic acid, glycine, and alanine.

  • In this paper, SOA Current and Temperature Driver which consisted of LabVIEW programming part capable of current and temperature transient response pattern design, DAQ module for analog voltage in&out, and voltage to current converting chips has realized. The output current(possible to 3A) from the Driver to SOA was clearly constant without ripple and also showed no variance until 1mA unit for a long time operation. The temperature of TEC took several seconds to reach a set temperature, and were maintained stably within ${\pm}^0.1{\circ}C$ for several hours. The proposed Driver can replace the previous high cost SOA Drivers for wavelength swept lasers fully and provides the convenience of transient response design capability for current and temperature.

  • We tried to improve the coating capability of the coating material using an additive(hexagonal cystalline graphite) of 2%, 3%, 4% and 6% under various pouring temperature for the easy isolation of sand and coating material from the final product. As a result in case of using a 2% and 3% additive generally no burning state has been occurred under the low pouring temperature, but it has been gradually increased with the pouring temperature. On the other hand in case of using a 4% and 6% additive there has been no burning state through out the whole pouring temperature. From this result we could see that the best state of the final product without sand and coating material could generally be obtained if 4% and/or 6% of the crystalline graphite and the pouring temperature of 140$0^{\circ}C$$\pm$5$^{\circ}C$ would be used.

  • Recently, knowledge transfer has been recognized as one of the major factors for success of IT projects but little investigated in Information Systems research. IT project, which needs collaboration between organization's IT project team and external partner, is an critical source for a firm to acquire external knowledge and to achieve its competitive advantage. Based on this recognition on knowledge transfer under IT project, we investigate a mediation role of knowledge transfer to IT project performance after identifying its antecedents such as project team capabilities and partner capabilities. The research model is tested by analyzing 161 sample data gathered from firms' employees who have participated IT projects within last two years. The results reveal that knowledge transfer has full-mediation effect between its antecedents and IT project performance. Moreover, project team capabilities have more impacts on knowledge transfer than partner capabilities do.

  • Engineering is a value-adding process applying knowledge and skills in the construction industry that includes the planning, feasibility study, project management (PM), front end engineering and design (FEED), detail design, procurement, construction, supervision, and operation. Among these engineering activities, FEED is defined as a comprehensive design practice in the early design phase focused on conceptual design and basic design. It is a particularly influencing area that determines the competitiveness of procurement and construction capability of construction firms (KNIN 2013). Nevertheless, previous studies in FEED have been limited to the design process, deliverable, or particular management technique (e.g. system engineering, collaboration, information etc.). In this context, the purpose of this study is to propose a comprehensive FEED business process structure for project management of thermal power plant construction projects encompassing the entire project life cycle. And an assessment methodology for FEED functions was developed. It is expected that the proposed structure of FEED functions and FEED evaluation methodology will contribute to improvement of competitive capability of engineering, procurement, and construction (EPC) companies.

  • We present interferometric modulators that reproduce RGB colors through the selective actuation of mechanically coupled mirror arrays having identical air gaps. The conventional transmittive interferometric modulators need additional backlights, which leads to high power consumption. The previous reflective interferometric modulators using ambient lights need three different air gaps for reproducing the three RGB colors, thus giving rise to process complexity. For process simplicity, we propose the use of reflective interferometric modulators that are capable of producing green, blue, red, and black colors with the aid of mechanically coupled mirrors with identical air gaps. In an experimental study, the present interferometric modulators reproduce green, blue, and red colors at the switching modes (000), (010), and (101). The spectrum peaks for the colors are measured at the wavelengths $511{\pm}5nm$, $478{\pm}3nm$, and $644{\pm}9nm$, respectively, with the bandwidths being $60{\pm}1nm$, $45{\pm}2nm$, and $105{\pm}4nm$, respectively; further, the maximum intensities of the colors are $77{\pm}5%$, $73{\pm}2%$, and $81{\pm}5%$, respectively. The black spectrum is measured below the intensity of $27{\pm}0%$. Thus, we experimentally demonstrate the color reproduction capability of interferometric modulators fabricated by using a simple process.

  • This study, examined Chilocorus kuwanae for biological control of Saissetia coffeae. We measured basic developmental characteristics of C. kuwanae and its capability to prey on the second-instar larvae of S. coffeae by indoor breeding under the following conditions: $25^{\circ}C{\pm}2^{\circ}C$, humidity $70%{\pm}5%$, and day length 16L : 8D. The average daily consumption of the second-instar larvae of S. coffeae by C. kuwanae adults was approximately 77.5 larvae/day, which was significantly 2.8 and 2.9 times higher than consumption by Chrysoperla carnea and Cryptolaemus montrouzieri, respectively. During the nymphal period, C. kuwanae consumed a total of 659.0 second-instar larvae of S. coffeae. The interaction between C. kuwanae and the second-instar larvae of S. coffeae varied according to their densities, with the increase in C. kuwanae consumption rate noted to decelerate and gradually level off at the maximum, rsembling Holling's Type II functional response. Duration of egg to adult development varied from 21.1 days to nearly 27.9 days at temperatures of $25^{\circ}C{\pm}2^{\circ}C$. Hatchability, pupation rate, and adult emergence were greater than 72.3%, 77.8% and 83.3%, respectively.

  • The purpose of this study is to examine the impact of PM consultant leadership competence on consulting repurchase intention and the impact of SME CEO participation on consulting repurchase intention. The validity of the measurement model was secured through CFA (Confirmative Factor Analysis) for the questionnaire data, and consistency was secured through the same method convenience, and significant results were obtained. In other words, not only the ability of PM consultant in repurchase of consulting is important, but also confirms that repurchase intention differs according to the participation of manager. Therefore, the performance that manager feels depends on the degree of manager's interest in repurchase and plays an important role in repurchase. As a result, it is important for PM to report to manager and / or make the manager participate in consulting process so that manager can be interested. In this study, it is difficult to generalize the relationship between PM's leadership role and manager's involvement in the repurchase intention. However, it is meaningful that PM's competence as well as management's participation are very important, and that this study figured out which drection PM's leadership should focus on. The purpose of this study is to investigate the effect of the variables on the repurchase intention.
