Grape seed oil was extracted using different preparatory treatments as follows: (1) grinding, (2) grinding and roasting, (3) grinding and wet- roasting, (4) grinding, roasting, and wet-roasting, and (5) grinding, wet-roasting, and wet-roasting. The highest antioxidant activity was obtained from the sample with the method (2). Initial states of oxidation were similar except method (1) that showed more oxidized state, being P.O.V.8. Acid values were observed in the range from 1.42 to 1.89. The lowest acid value was found as 1.42 in method (1) and those of others were somewhat higher, indicating that heating process of roasting produced some free fatty acids. From the results of sensory evaluation, the best odor and taste were obtained from the methods (2) and (3). Repetitive procedure of wet-roasting, like method 5, caused some loss of flavor components and decrease in the sensory evaluation score. Addition of grape seed oil (method 2) to soybean and perilla oil at the level of 20% retained considerable antioxidant activities as much as 4.3 and 5 times, respectively, than 100% soybean or perilla oil stored for 12 weeks. When soybean or perilla oil was mixed with 20% grape seed oils, P.O.V. decreased to half of that of unmixed oils.

In recent years, there has been a gradual increase in the number of R&D projects for solving societal problems. However, government-funded research institutes(GRIs) are going through many trials and errors due to the lack of R&D systems suitable for solving societal problems. In this regard, this study attempted to discuss the improvement directions for evaluation systems of GRIs, which serves as a major influencing factor in performing R&D initiatives for solving societal problems. Towards this end, a study of R&D initiatives for solving societal problems was conducted first, and improvement directions for effective promotion were presented after deriving limits in terms of R&D initiatives for solving societal problems, along with the current status of evaluation systems by GRIs. Lastly, implications and limitations of this study were discussed. This study has its significance in that it is the first research to propose evaluation indicators in terms of solving societal problems at the level of GRIs and is expected to be a foundation for future research of related fields.

Government promotes that the strategy of national R&D converts from catch-up R&D type to leading R&D type for the future growth and national competitiveness according to the recent paradigm shift in the research and development. So the many national researches about foundation, source and core technology are actively being made. As a result of these researches, the security has become an important part of success factor in R&D. And so various security diagnosis and evaluation is being conducted about national R&D program. Existing the research security evaluation models are classified domains in terms of security management and created evaluation indicators according to the domains. However the models are inappropriate in case of researchers doing self-diagnosis of research security. This paper set up the domains in aspect of research management and then proposed the evaluation indicator of research security according to the domains. The evaluation indicator model that is suggested can be utilized in self-diagnosis of research security effectively.

Recently as the advent of knowledge-based competition, the major industrialized countries including Korea, are expanding their R&D investment and promoting policies for diffusing of R&D performance. For this, NASA, DoD and such agencies in the United States define Technology Readiness Level (TRL) as a quantified indicator for performance management, and also impose Technology Readiness Assessment (TRA) as a evaluation system, that evaluates technology maturity using TRL. These tools are judged to be very effective in R&D projects especially with the object of practical use. When this concept is applied to the domestic national construction and transportation R&D project for the purpose of practical use, it is expected that the evaluation system overcomes its weakness of focusing only on academic results and improves significantly on intent of achieving practical use. Thus in this study, TRL/TRA implementation model of construction and transportation R&D project for achieving purpose of practical use is presented through an analysis of TRL/TRA concept and domestic national construction and transportation R&D project's characteristics and current evaluation/management system.

Advances in information technology, communication and network technology are radically facilitating digital convergences as the integration of human, equipment, and space in the current industry 4.0 era. In industry 4.0 environment, the vast amount of information with networked computing technology can be simultaneously accessible even in limited physical space. Two main benefit points out of these information are the convenience and efficiency in their online transactions either buying things online or selling online. Even though there exist so many benefits that information technology can create for the people doing business over the internet there is a critical problem to be answered. In spite of many such advantages, however, online transactions have many dysfunctions such as personal information leakage, account hacking, and cybercrime. Without preparing the appropriate protection methods or schema people reluctantly use the transaction or would find some other partners with enhanced information security environment. In this paper we suggested a novel selection criteria that can be used to evaluate the reliable means of authentication against the expected risks under on-going IoT based environment. Our selection criteria consists of 4 steps. The first step is services and risk identification step. The second step is evaluation of risk occurrence step. The third step includes the evaluation of the extent of damage. And the final step is the assessment of the level of risk. With the help of the above 4 step-approach people can systematically identify potential risks hiding in the online transactions and effectively avoid by taking appropriate counter actions.

This paper proposes an accelerated life evaluation of drive shaft for the power train parts of special purpose vehicle. It is necessary the real load data of usage level driving load condition for life evaluation of power train parts, but we can't get the load spectrum data for evaluation in many case of special purpose vehicle. So, in this paper, the road load spectrum data for evaluation is created by modeling and simulation based on vehicle data and special road condition. The inverse power model is used for accelerated life test. The equivalent torque of load spectrum is achieved using the Miner's Rule. This paper also proposes the calibrated acceleration life test method for drive shaft. The fatigue test is performed through three stress levels. The lifetime at normal stress level is predicted by extrapolation, and is verified through comparison of experimental results and load spectrum data.

This paper proposes a new methodology for adequacy evaluation of composite power system considering an ambiguity of overload of transmission lines. Nodal arrival powers under considering an ambiguity of overload of transmission lines can be evaluated using the proposed method. Fuzzy set theory has been used in order to consider the permission level of overload of transmission lines. The problem of adequacy evaluation has been formulated using fuzzy linear programing. The effectiveness of the proposed method considering permissible overload of transmission lines has been demonstrated on the IEEE RTS.
