Purpose: The extraction conditions for bioactive components from peanut shells, which is a byproduct of peanut processing, were optimized to enhance the total phenolic content (TPC, Y1), total flavonoid content (TFC, Y2), and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (RSA, Y3). In addition, this study evaluated the anti-obesity effect of peanut shell extract. Methods: Optimization of ultrasonic-assisted extraction (UAE) was performed using a response surface methodology. The independent variables applied for extraction were time (X1: 5.0-55.0), temperature (X2: 26.0-94.0), and ethanol concentration (X3: 0.0%-99.5%). Quadratic regression models were derived based on the results of 17 experimental sets, and an analysis of the variance was performed to verify its accuracy and precision of the regression equations. Results: When evaluating the effects of independent variables on responses using statistically-based optimization, the independent variable with the most significant effect on the TPC, TFC, and RSA was the ethanol concentration (p = 0.0008). The optimal extraction conditions to satisfy all three responses were 35.8 minutes, 82.7℃, and 96.0% ethanol. Under these conditions, the inhibitory activities of α-glucosidase and pancreatic lipase by the extract were 86.4% and 78.5%, respectively. Conclusion: In this study, UAE showed superior extraction efficiency compared to conventional hot-water extraction in the extraction of polyphenols and bioactive materials. In addition, α-glucosidase and pancreatic lipase inhibitory effects were identified, suggesting that peanut shells can be used as effective antioxidants and anti-obesity agents in functional foods and medicines.

Current status of the domestic food industry and major issues are reviewed, and some problems derived from the R&D aspect are analyzed. Particularly, the role of the public sector and the direction of R&D are presented in order to enhance the vitality of the food industry and strengthen the competitiveness of small and medium-sized businesses. At first, the government needs to provide a consistent R&D roadmap through macroscopic coordination, and public institutes and private companies should come up with practical and concrete collaborative measures. It is also necessary to set the investment direction for food R&D in the public sector, taking into account the strategic importance of core technology and the global level difference, targeting on basic research and public platform technology. More efforts to discover agendas focused on food technology and link them to large-scale R&D projects are urgently needed to solve national and social problems through food research.

The expansionary monetary policy was practiced after 2001 in Japan to treat the deflation spiral, and reduced only the nominal interest rates and domestic household demand. One of the most serious factors for this failure was the change of private sector's expectancy. This paper has studied the effect of Japanese monetary policy in 21c., with empirical research based on a renewed macroeconomic model and the VAR. The empirical analysis shows that the effect of monetary policy on the national income during 2001.01-2015.03 is weaker than that of 1985.01-1994.04. Money volume has a diminutive effect on the growth of GDP within a short term after 2001. The change in the expectations of the private sectors might have been the cause of ineffectiveness of the expansive monetary policy. Economic agents learned from the past Japanese financial crisis that an expansive monetary policy increased the inflation rate and caused the 'bubbles to burst' afterwards. The VAR analysis says that the effectiveness of monetary policy on the economic depression declined over the past 20 years and the expansion of money volume has no influence on exchange rate and net export. This means that the expansive monetary policy lost its effect on net export and national income steadily. Monetary policy makers have to recognize this fact, and to consider another anti-cycle political instrument, i.e. the fiscal policy with government debt.

This Study aims to evaluate teacher policy in the Park Administration and to suggest tasks based on the results. To attain the aim, it describes overall teacher policy process in Park Administration and evaluates teacher policy based on the criteria which was driven from the CIPP model. The conclusions are summarized as follows. First, the environmental suitability of the situation assessment was met in general. The reason for this was that the teacher policy of the Park Geun-hye government was introduced reflecting changes in the environment and demands of policy stakeholders. The validity and feasibility of the policy objective of the input evaluation were not satisfied. There were deficiencies in the objectives of the policy measures. The objectives of the measures were not linked to the policy objectives. The budget necessary for policy enforcement were not secured. In future policy design, efforts should be made to examine whether the policy goals are valid, to secure resources necessary for policy implementation and to increase the feasibility of policies. The procedural rationality of the process evaluation and the suitability of the means were not met. Discussion with the interest group was omitted, it was not clear whether the implementation of the policy was linked to the policy goal. In the future, it will be necessary to focus on procedures such as communication and collaboration with stakeholders, to make immediate revisions in case of problems. The effectiveness and satisfaction of the output evaluation were low. Because the validity of the policy objectives, the suitability of the means, and procedural rationality were not satisfied. In the future, it will be necessary to systematically design policies and communicate with stakeholders in the execution process to prevent policy failures and actively.

This study was designed to analyze instructors's perceptions on legislation of the amendments of the Higher Education Law in 2011 and discuss some issues related to direction for revision henceforth. This study explored two research questions. First, how do instructors perceive the legislation of the amendments of Higher Education Law? Second, how do they think the directions for the revision of the law? To complete this task, the author conducted in-depth interviews with 16 interviewees; 13 instructors and 3 specialists of the higher education. As a result of in-depth interviews, the author found that instructors perceive the law as condescending law or election-based law even though they recognize the significance of the law. They predict that the law can increase non-tenure track faculty members. In addition, they emphasize the law should be revised to improve the instructors' labor condition substantially, for instance increase of the teaching pay and employment stabilization. However, instructors' opinions on the law itself and its revision direction are divided according to their age and major. Based on the results of this study, I discussed some potential issues of the revision of the law and suggested improvement plans.

As the 'hyper-connected society' has emerged through the 'Fourth Industrial Revolution, public interests as well as social dangers have increased. Above all, the risk of infringement of information, including confidential personal information, is dramatically increasing. As the hyper-connected society has been realized, even if only one of the internet devices is hacked, there would be a danger that the ripple effect of such a hacking spreads to the whole network. Therefore, the necessity and importance of information security, including cybersecurity, has been increasing. In other words, the stability of cyberspace and internet space is becoming more important. As a result, the Korean government is seeking to build a legal system related to information security, which would be able to cope with the information infringement problem in the hyper-connected society. However, it seems that the government is still struggling with the direction of building such a legal system. In this context, a comparative review examining the legal systems of advanced foreign countries will provide meaningful implications as to what kinds of legal policies we should devise and implement for information security. In particular, the U.S. legislative act that actively responds to the cybersecurity violations is worthy of reference. For this reason, this article systematically analyzes the current status of the U.S. cybersecurity laws. Especially, this article focuses on the "Cybersecurity Information Sharing Act of 2015"(hereinafter "CISA"), that was recently enacted by the U.S. congress. The CISA prescribes the systemic and detailed information-sharing between national and private entities. The CISA, that actively promotes information-sharing, is full of suggestions for us, in that information-sharing is an effective way to properly realize information security in today's hyper-connected society.

One of the current issues in Workers' Compensation Insurance is about the coverage range. Korea uses the definition of worker under the Labor Standards Act in Workers' Compensation Act and solved the problems associated with the coverage range of insurance group by the exceptional clause only for the groups which was raised about the need for the social protection. The purpose of this paper is to draw implications for solving problems which are associated with the coverage range of insurance group by reviewing the German literature. We focus on volunteers and persons in special types of employment. German government supports the activity of volunteers by providing with the protection service against the accidents. This paper shows how the coverage range is extended from the dependent employees in the introduction of the Workers' Compensation Insurance to the people who need social protection focusing on the volunteers. The implications of this research are following. First, German system shows that Workers' Compensation Insurance can be extended to the groups which do not belong to the dependent employee but are worthy of protection. Second, it is necessary to provide volunteers in the social welfare system with the protection service against the accidents and the statutory accident scheme is recommendable to use. Third, volunteers in the social welfare system need to be compulsory insured. Fourth, Korea should find their own way in solving problems associated with persons in special types of employment.

19C was a chaotic time of Chosun dynasty, in order to make society stable, the scholas of Chosun wanted to define themselves as a little China on the east", to understand themselves as part of China and somehow they thought it will help for Koreans to understand who they really are. This "Chosun as a little China" idea is their spritual foundation and also the to understand who they are. From 16 C, Chosun had idea of "being a little China, so when Hwaseo talked about this idea, it was not new to the people and scholars in Chosun, however in Hwaseo's theory, the idea was more defined and realistic. In 19 C Chosun dynasty, the chaos caused by absece of fundimental principle was great, the scholars agreed Hwaseo's "Chosun as a little China" theory should be the foundational principle. Therefore, the problem of understanding and communicating about the west has to be reconcidered, because that was what they wanted to have as foundation before the comunication with west. Scholas of Chosun wanted to set their foundation before they often up their country to the west so they needed time to discuss this. In 19 C Japan on the other hand, they faced same chaos that Chosun experienced, however they went totally different way, because Japan unerstood the reallity and accepted western civilization. Specially, the latter period Mito study influenced to make that decision by changing the west from what they have to defeat to what they have to respect and copy. Both Chosun and Japan focused on making thier countries stronger, but Chosun found the answer in focusing on orthodox confucianism and Japan found the answer in making the military stronger. That is why these two countries went totally different ways in the history of 19-20 C North-east Asia.
