This paper analyzes how the adverse impacts of the global financial crisis on Korea's employment could be mitigated in comparison with the Asian crisis period. The results from error-correction models suggest that the less severe impacts during the global financial crisis could be attributed to (i) smaller GDP reduction, (ii) better maintenance of domestic demand despite a sharp fall of export, (iii) less serious over-employment during the run-up to the crisis, and (iv) less severe credit crunch. Analyses of OECD cross-country data provide corroborating evidence. In order to mitigate adverse impacts on employment, therefore, priority should be given to expansionary macroeconomic policies to keep aggregate domestic demand from collapsing once a crisis is triggered. Also crucial, however, is to maintain sound economic structures such as flexible labor market and adequately supervised financial market.

IMF로 인한 경제위기 시기에 도시에서 농촌으로 귀농 가구가 증가하는 현상이 나타났으나 이후 경제가 활성화 되면서 감소하였다. 연도별 귀농가구의 동향은 1998년 6,409가구를 정점으로 1999년에 4,118가구로 감소하였다가 2001년경에는 매년 1000가구 미만의 수준으로 하락하였으나 2008년 말 기준으로 2,218가구에 이르는 비교적 증가하는 추세를 보이고 있다. 한편 지방자치단체 특히 인구 과소화 시군에서는 도시민 유치를 위하여 경쟁적으로 귀농자 지원조례를 제정하여 정착하는 귀농인들을 지원하고 있다. 급기야 2009년 4월에는 중앙정부 차원에서 '귀농귀촌 종합대책'이 발표되었다. 도시에서 농촌으로 이주하는 원인으로는 농업을 직업으로 선택한 결과에 따른 것도 있지만 건강한 생활 및 웰빙 전원생활 영위를 위한 이주 등 그 원인이 다양화 되어 가고 있다. 이주하는 개인의 다양한 동기와 함께 지방자치단체의 지원책 또한 하나의 유인요인이 된다고 할 수 있을 것이다. 귀농귀촌 인구가 증가세를 보이기 시작한 2000년대 중반은 정부와 지방자치단체의 귀농귀촌인 지원대책이 시작된 시기임을 볼 때 그 연계성을 짐작할 수는 있으나 검증된 바는 없다. 그렇지만 귀농인의 입장에서는 선배 귀농인이 많이 거주하거나 지원정책이 잘 되어 있는 곳을 선택하게 될 가능성은 높은 것도 사실이다. 본 연구에서는 귀농인 지원을 위하여 각 지방자치단체가 제정한 지방조례의 내용과 차이점을 분석하고자 한다. 2009년 6월 기준으로 전국 34개 시군에서 지방조례를 제정하였고 이중 13개 시군에서는 시행규칙도 완비하였다. 조례의 주된 내용은 귀농귀촌인에 대한 빈집수리비용, 의료 학자금, 영농정착금, 농지구입자금 등을 지원하는 것으로 되어 있다. 물론 그 지원 규모에 있어서는 다소의 차이가 있지만 귀농귀촌인에 대한 자금의 직접적 지원에 초점이 맞춰져 있다. 귀농자들이 지역사회에 안정적으로 정착하고 정주할 수 있으려면 직접적 자금지원을 벗어나 지역네트워크를 형성하고 지원해 주는 것이 필요할 것으로 사료된다.

As the word 'creation and innovation' has been the keyword in success, there has been an increasing interest in TRIZ (Theory of inventive problem solving). So far, TRIZ has been applied to electronics and mechanics as the prime mover of product innovation. This study is to explore the applicability of TRIZ to the biotechnology sector, a future emerging technologies, especially to problem solving and innovative research and development. This study was focused on red ginseng processing. Problem causes and contradictions were identified with regard to processing-related problems, and 'the 40 principles of invention' were applied to problem solving. Steamed fresh ginseng is called 'Red ginseng'. Cracks in red ginseng cause the loss of active ingredients and also are not of merchantable quality. In the 40 principles of invention, applicable ones were finally selected through contradiction matrix and brainstorming, the tools of TRIZ. With experiments, effective methods were suggested to prevent red ginseng from cracking in a steaming process.

Existing studies have shown consistent results that a diversification discount phenomenon occurs, which means that the value of the company decreases as the degree of diversification of a company increases. Nevertheless, it is explained by the agency theory as a factor that continues to promote diversification by companies. And in order to solve the agency problem, it is important to form an effective governance structure. In order to solve these problems, this study aims to study how the directors' concurrent information affects the monitoring effect of the board of directors through this affects diversification.To this end, research was conducted on KOSPI companies for 6 years from 2011 to 2016.As a result of the analysis, in the case of the concurrent appointment of the CEO and the inside director, there was a positive (+) effect, but the significance could not be confirmed. In the case of adjunct appointments as outside directors, positive results were confirmed that were significant for diversification.

Composite materials are currently used in aero-space industry, sport and leisure industry but it has many problems such as mechanical properties deterioration by moisture absorption. In this study, we appraised interlaminar shear strength with specimen that immersed/ immersed-dried in water environment(distilled/sea) during $100{\sim}200$days. In the result, properties degradation of resin part and silan part by moisture absorption is judged early on main cause of interlaminar shear strength, and later destruction of mechanical bonding between silan part and fiber by moisture absorption is Judged later main cause of interlaminar shear strength. In conclusion, the recovery of interlaminar shear strength is judged to difficult due to interfacial destruction by moisture when pass over irreversible by moisture in composite material.

도시하천은 급속한 경제성장과 개발 등 여건변화에 따라 크게 변화되어왔다. 이에 하천은 본연의 모습과 가치를 잃고 인공적인 모습으로 변해 하천의 주요 기능인 자정작용, 생태계 건강성 유지 등의 기능을 잃고 도시 활동에 따른 오염물질에 노출되어가고 있는 실정이다. 이로 인한 부정적인 영향으로 도시민의 삶의 질과 만족도 또한 하락되고 있다. 본 연구에서는 부산의 대표하천인 수영강을 대상으로 도시하천 수질 개선을 위한 도시민의 지불의사를 추정하였다. 비시장가치를 추정하기 위해 조건부가치측정법(CVM, Contingent Valuation Method)을 적용하여 수질개선에 따른 지불의사(WTP, Willingness To Pay)를 파악하고 경제적 가치를 추정하였다. 가상시나리오는 EPA, water quality ladder의 개념을 이용하여 현재 수영강 수질이 오염된 물(4등급)이라고 가상시장을 설정하고 낚시가 가능한 수준(2등급)까지 개선을 시키고자 할 때의 지불의사를 물었다. 이때 지불수단은 기부금의 형태로 연 1회 향후 5년간 지불기간을 설정하였다. WTP 모형추정은 KDI에서 제시하고 있는 로지스틱분포 함수와 스파이크 모형을 사용하여 WTP를 추정하였다. 스파이크 모형의 추정결과 평균 지불의사액은 12,255원으로 부산광역시 전체 가구 수인 1,392,291가구(2019년)에 적용할 경우 향후 5년간 연 170억 원의 재원을 확보할 수 있는 것으로 나타났다. 지불의사 추정결과 수영강 인접 지역주민의 지불의사가 높게 추정되었고, 부산시민이 수영강을 자연과 생태보전 기능하천으로 인지하고 있음(56.5%)을 고려 할 때, 하천환경개선을 통한 지불의사의 상승은 도시하천 가치 향상이 될 수 있을 것으로 판단된다. 또한 도시민의 기대수준 충족과 더불어 도시하천 가치상승을 위한 부족한 재원까지도 조달 할 수 있는 방안의 기초를 마련 할 수 있을 것이라 판단된다.

This study conducted a quantitative research on the artistic perception and acceptance of value among buyers of commodified digital art known as NFT artworks. NFTs, digital assets, have shown rapid growth as investment products, but recently there has been a trend of declining value. However, NFT art, characterized by uniqueness and scarcity, continues to undergo continuous development to create new opportunities and values. Nonetheless, there are also negative opinions regarding NFT art itself as a form of technological art, as well as concerns about copyright disputes and fears of a bubble due to the conversion of physical artworks into NFTs. Predicting the value of artworks targeting specific demographics is difficult, and the value of innovative art such as NFT art, which changes along with the fluctuation of cryptocurrency values, is even more challenging to predict. Therefore, through research on the buyers who play a crucial role in the growth and development of this new form of art, the study aims to contribute to the expansion of NFT art.

This study is carried out to find out Chinese cabbage price sensitivity of consumer. Even though Chinese cabbage is the most important vegetable in our country, the price fluctuation continues to be changed ever year. However, there was no price criteria which is low, high, optimum price level for stabilization policies. In this paper, we investigated urban consumer price sensitivity by using the price sensitivity measurement(PSM), and then suggest to farmer and policy maker the results. The purchasing attribute Chinese cabbage of consumer will be provided to farmer. Optimal willingness to pay price of Chinese cabbage was analyzed between 1,991~2,018 won per head. If the consumer price were formated that price range, the costs will be able to satisfied both producers and consumers. The consumer's acceptable price range was from lower price (PMC) 1,472 won to the upper limit price of 2,714 won (PME). So when the market price researched above 2,714 won, import should be considered. The most important attribute when purchasing was a taste of cabbage, and he most suitable size was 3kg per head.

This paper studies the stock market in which there are two types of investor, institutional and individual, whose information gathering and processing abilities are different. The institutional investor manages large funds and has powerful information sources. Whereas, the individual investor trades with a small amount of money and an information disadvantage. The model assumes that the institutional investor is more experienced and able to acquire relevant information earlier than the individual investor. On these assumptions, this paper shows a price continuation in the short run and a price reversal in the long run. The price continuation, or momentum, in the short run can be explained as follows. The early-informed institutional investor trades a stock, and as a result the stock price changes. Then the late-informed individual investor trades the same stock, and the stock price continues to move in the same direction in the short run. The reason for the price reversal in the long run is that since the individual investor has inferior information on the fundamental value of the stock, he tends to overreact to new information. So the stock price changes over its fundamental value initially and then regresses toward its fundamental value. In sum, both the price continuation and the price reversal are caused by the overreaction of the individual investor. The essay illustrates how these phenomena are stronger in the case where the proportion of the individual investor is higher. It also shows how the stock price goes up when the institutional investor buys a stock, while it goes down when the individual investor buys one.

Since 2010, Korea's overseas construction orders have seen dramatic fluctuations. I propose causes and remedies for the industry as a whole. Orders have recorded an annual average of $63.8 billion dollars from 2011 to 2014, reaching its highest at $71.6 billion dollars(2010) which marked the peak of Korea's overseas construction. However, due to a decline in international oil prices, starting in the last half of 2014, Korea's overseas construction orders have followed suit recording $46.1 billion dollar in 2014, $28.2 billion dollars in 2016, and $29.0 billion dollars in 2017. Facing uncertainty in Korea's overseas construction market, caused by continued slow growth of the global economy, Korean EPC contractors are at a critical point in regards to their award-winning capabilities. Together with declining oil prices, the challenges have never been bigger. To mitigate the challenges, I would suggest policy direction as a way to grow and develop the overseas construction industry. Proper counterplans are needed to foster Korea's overseas construction industry. Forecasting total order amount for overseas construction projects is essencial. Analyzing contract award & tender structure and its changing trends in both overseas and world construction markets should also be included. Korea has great potential and global competitiveness. These measures will serve to enhance Korea's overall export strategy in uncertain overseas markets and global economy.
