Entertainment Industry is a high value-added business and its market includes the whole world. With high-tech industry, it is said that entertainment industry strengthen country's competitiveness, and the Korean government is trying to find a way to develop the animation industry. Some domestic feature animations were made, but they failed to get sufficient audiences. Meanwhile, Shrek 2, made by PDI, has earned about 92,000,000,000$ through just theatrical revenue. The reason is that domestic animations are not exciting. Contents should have amusement in it. The humor is the most important thing to make fun. So this thesis suggest to analyse Humor Types in animations. It is based on several theories about Humor. The types of humor defined by the previous studies are summarized into (1) humor, (2) wit, (3) satire and (4) irony. I categorize the productive methods of visual humor into (1) visual pun, (2) visual parody and (3) visual paradox adopting Henri Bergson's theory of the production methods of humor. And I comment on humorous scenes of Shrek in points of design basic elements, such as (1) visual elements, (2) relational elements and (3) practical elements. And I classify humor responses into the incongruity theory, the superiority theory, and relief theory. Therefore this study suggest a reasoned method to categorize the humor types effectively for producing or analyzing various types of humor effects in animation fields.

국내의 수자원장기종합계획(건교부, 2001년)에 의하면 농업용수는 우리나라 수자원의 48%를 차지하고 있으며 하천유지용수를 제외한 이용량으로 보면 62%에 해당하는 최대 용수이용 부문이다. 그러므로, 농업용수의 효율적인 계획과 관리는 우리나라 수자원의 효율적인 이용에 있어서 매우 중요하다. 우리나라의 농촌은 1970년 이후 급격한 도시화, 산업화로 농업인구의 격감과 노동력의 부족에 따른 농업용 기계가 보급되게 됨에 따라, 과거의 주로 인력에 의한 벼농사의 영농방식에 변화가 생기게 되었다. 그러한 영농전반의 변화들은 직파재배, 집단육묘, 비닐하우스를 이용한 못자리, 어린모 이앙법 등 다양한 방식으로 벼재배 방식에서도 나타나고 있다. 이러한 영농상황의 변화는 농업용수공급 현황에도 영향을 미쳐 물이용 형태가 과거와 많은 차이를 보임을 알 수 있다. 이러한 차이는 최근의 연구결과에서도 나타나고 있는데 2002년 농어촌연구원 '용수수급의 안정성 제고 연구 및 종합시험지구 운영'에 의하면 3개 저수지지구의 계획공급량과 용수공급량 비율이 $0.7{\sim}1.3$이며, 영농초기 $4{\sim}5$월에 특히 차이가 큼을 알 수 있었다. 2001년 한국건설 기술연구원의 '물관리 효율성 제고기술 연구보고서'에 의하면 $4{\sim}5$월에 큰 차이를 보이는 등 농어촌연구원과 비슷한 결과를 나타내었다. 본 연구는 중부지방인 경기 남부지역을 대상으로 영농방식에 대한 조사를 하고 농업용수 공급량을 측정하여 현행 농업용수량 산정기준에 의한 농업용수량과 비교함으로써 변화된 영농환경을 고려한 적정한 관개 용수량 산정방법을 제시하는 것을 목적으로 하고 있다.악할 수 없었던 수체내의 많은 특징을 파악 할 수 있었다.. 중랑천 유역의 소배수구역을 대상으로 연중 발생하는 큰 호우사상에 대해 임의의 강우관측소를 결측지점으로 가정하고 주변의 강우관측소로부터 각각의 방법을 이용해 가중치들을 산정하여 결측지점의 강우량 값을 보정하고자 하였다. 또한 각각의 방법을 이용하여 얻어진 결과에 대해 실측값과 보정값의 오차정도를 평균절대오차법(Mean Absolute Error)과 제곱평균제곱근오차법(Root Mean Squared Error)에 의해 산정하여 보정 방법간의 효율성을 검토하고자 하였다.9년, 그리고 2010년${\sim}$2019년까지 총 4구간으로 나누어 결과를 도출하였으며 예상한 바와 같이 후반기 20년 동안에 세 가지 지표가 취약해 지는 것을 확인할 수 있었고, 특히 2000년부터 2009년까지 10년 동안에는 더욱 취약해짐을 확인할 수 있었다.를 보임에 따라 그 정책적 효과는 때로 역기능적인 결과로 초래하였다. 그럼에도 불구하고 이 연구결과를 통하여 최소한 주식시장(株式市場)에서 위탁증거금제도는 그 제도적 의의가 여전히 있다는 사실이 확인되었다. 또한 우리나라 주식시장에서 통상 과열투기 행위가 빈번히 일어나 주식시장을 교란시킴으로써 건전한 투자풍토조성에 저해된다는 저간의 우려가 매우 커왔으나 표본 기간동안에 대하여 실증분석을 한 결과 주식시장 전체적으로 볼 때 주가변동율(株價變動率), 특히 초과주가변동율(超過株價變動率)에 미치는 영향이 그다지 심각한 정도는 아니었으며 오히려 우리나라의 주식시장은 미국시장에 비해 주가가 비교적 안정적인 수준을 유지해 왔다고 볼 수 있다.36.4%)와 외식을 선호(29.1%)${\lrcorner

This study was carried out to get the basic information of irrigation plans for the red pepper, such as optimum irrigation level and irrigation requirement in Taegu and Kyungpook province. In this study, red peppers were cultivated in 6 PVC pot lysimeters filled with 60cm deep clay loam soil. Four tensiometers were installed in each plot to measure the soil water pressure head. Field measurements were made during the period June 6 to October 31, 1988 at the experimental farm of Kvungpook National University. Six levels of irrigation were used. They were PF 1.8-2.0, PF 2.2-2.4, PF 2.8-3.0, FC-PF.1.7, FC-PF 2.2, and FC-PF 2.7. The results obtained from this study are summarized as follows : 1. In case of irrigation levels of narrow ranges of water contents, the higher the soil water content was, the larger the ET was. Hut in case of the irrigation levels returning to the field capacity, the lager the PF value of irrigation point was, the larger the ET was. Considering ET, yield and weight per fruit, the latter is much better than the former irrigation method. 2. The mean daily ET and mean ET ratio for each 10-day period showed that the maximum value occured in the last of August. The ranges of those were 3.74-14.64 mm/day and 0.87-3.40, respectively. These values showed that small during the early stage of growth, large during the middle stage and getting smaller in the last stage. 3. In case of irrigation levels of narrow ranges of water contents, the increase of irrigation water supplied increased the ET. The relationship between the two showed nearly straight line. Most of irrigated water was consumed as ET and the rest as percolation. But, in case of irrigation levels returning to the field capacity, the higher the PF value of irrigation point was, the larger the ET ratio was. However, their relationship didn't show straight line. 4. The irrigation level of PC - PP 2.7 was found to be the optimum irrigation level with respect to the yield, the weight per fruit, stem length, irrigation requirement and percolation quantity. In this case, mean daily ET and mean ET ratio were 6.79 mm/day (total 10052 mm) and 1.67, respectively. The maximum mean daily ET and mean ET ratio for 10-day period were 14.64 mm/day and 3.40, respectively, in the last of August, and the maximum daily ET was 2126 mm/day on August 24. 5. In case of PC - PP 2.7 which is found the optimum irrigation level, mean irrigation water required, mean ET and mean percolation water quantity were 7.44 mm/day, 6.79 mm/day(91.3% of irrigation water), and 0.38 mm/day (5.5% of it), respectively.

Pleurotus eryngii is by far the best tasting oyster mushroom, well deserving of the title, the King Oyster. Popular in Europe, this stout, thickly fleshed mushroom, is one of the largest species in the genus. The effects of addition of crab shell to sawdust substrate for the growth of P. eryngii were investigated. Dried crab shell used in this study contained 55.2% C, 3.74% N, 5.57% $P_2O_5$, 6.44% Ca, and pH 6.9. The addition of 1% crab shell (v/v) increased the yield of the mushroom fruit-body by 34% comparing control (sawdust 80, rice bran 20; v/v), 0.03% CaO content of 1% crab shell treatment was higher than 0.01% CaO of control and period of primordia formation was similar regardless of the treatments.

The technology for hydrothermal reaction of organic waste is one of the promising process to improve energy efficiency of biomass waste recycling system since moisture contents of treated biomass could be reduced at 40% or less than by dehydration processes. For these reasons, many parts of the world are interested in hydrothermal reaction of organic waste. In this paper, drying performances were evaluated with and without hydrothermal reaction of organic wastes which are sewage sludge and food wastes. For the hydrothermal reaction, organic wastes were treated at $200^{\circ}C$ for 1hr. Drying time of treated organic waste by hydrothermal reaction was reduced. In case of food waste drying at $100^{\circ}C$, drying time of treated wasted was reduced more 52.9% than non-treated. Hence, drying performances of sewage sludge and food wastes should be improved by hydrothermal reaction. Drying rates of treated wastes were considerably increased at preheat period of drying characteristic curve as followings; at $80^{\circ}C$ sludge as 148%, $100^{\circ}C$ sewage sludge as 151%, $80^{\circ}C$ food waste as 209%, $100^{\circ}C$ food waste as 366%. It means the surface area of treated wastes could be increased with destruction of cell membrane by hydrothermal reaction. However, the designer and operator of drying process should be careful, since enhanced drying rate cause the extension the decreasing drying period.

Including the rolling black out in 2011, Korea has suffered from rapid increase of electricity consumption and demand forecasting failure for last five years. In addition, because of the Fukushima disaster, high fuel prices, and introduction of new generation sources such as renewables, the uncertainty on a power supply strategy increases. Consequently, a stable power supply becomes the new agenda and a revisino of strategy for new power generation sources is needed. In the light of this, we appraises the sixth basic plan for long term electricity demand and supply considering the changes of foreign and domestic conditions. We also simulate a strategy for the new power generation sources using a portfolio analysis method. As results, a diversity of power generation sources will increase and the share of renewable power generation will be surged on the assumptions of a cost reduction of renewable power sources and an increase of fuel costs. Particularly, on the range of a risk level(standard deviation) from 0.06 and 0.09, the efficient frontier has the most various power sources. Besides, the existing power plan is not efficient so that an improvement is needed. Lastly, the development of an electricity storage system and energy management system is necessary to make a stable and efficient power supply condition.

Due to increased consumption and demand for oat-related foods and processed food, this study examined physicochemical properties, antioxidant activity, and ${\beta}-glucan$ contents of 5 Korean naked oat cultivars. Oat seeds had long-grain appearance in all cultivars except for Seonyang. The contents of main components such as protein, starch, and crude fat were significantly different among cultivars. The total ${\beta}-glucan$ content was 3.78-4.60% and the soluble ${\beta}-glucan$ ratio was 71-83%. Fatty acid composition was C18:1, C18:2, C16:0, C18:0, and C18:3. Unsaturated fatty acid (USFA) content was 75.4-81.2%. 2,2-Diphenyl-1-picrylhydrazil (DPPH) and 2,2'-azino-bis-3-ethyl-benzo-thiaxoline-6-sulfonic acid (ABTS) radical scavenging activity were significantly different for each cultivar. Daeyang had the highest ${\beta}-glucan$, USFA content, and antioxidant activity. Protein content showed a negative correlation with starch content (r = -0.775). Antioxidant activity was positively correlated with total phenol content (r =0.760). Ash content and flour whiteness showed a positive correlation (r =0.732).

This study aimed to collect the carbon dioxide generated as a by-product from petrochemicals and liquor factories and use it in a crop breeding greenhouse. This was applied mainly to the storage of dry ice and the supply of carbon dioxide to achieve this target. Dry ice has a strong cooling effect because CO₂ becomes a solid or gas at temperatures and pressures below the triple point, and the solid sublimes at -78.5℃ and atmospheric pressure. The consumption of dry ice according to temperature was 0.983kg/day, 2.358kg/day, 5.102kg/day, and 7.035kg/day when the temperature was 5℃, 10℃, 15℃, and 20℃, respectively, which corresponded to 1,102ppm, 1,481ppm, 1,677ppm, and 1,855ppm. Dry ice consumption in the test greenhouse decreased by approximately 0.9kg/h, and the CO₂ concentration in the greenhouse at 9 a.m., before supplying dry ice increased to 517ppm, 1,519ppm at 10 a.m., 1,651ppm at 11 a.m., and 1,651ppm at 12 p.m., before maintaining this level of activity. Overall, this study attempted to contribute to increasing farm income by deriving the supply conditions through an expansion of the supply of carbon dioxide gas for crops.

The current growth of nano-industries has resulted in released nanoparticles entering into water and soil ecosystems via various direct or indirect routes. Physicochemical properties of nanoparticles differ from bulk materials, and nanomaterials influence the fates of nanoparticles and the interactions of living or non-living things in the environment. Microcosm analysis is a research methodology for revealing natural phenomena by mimicking part of an ecosystem under controlled conditions. Microcosm study allows for the integrated analysis of toxic effects and fates of nanoparticles in the ecosystem. Ecotoxicity studies of nanomaterials are steadily increasing, and microcosm studies of nanomaterials are currently beginning to surface. In this study, microcosm studies of nanomaterials in water and soil ecosystems were extensively investigated based on SCI(E) papers. We found that the microcosm studies have been reported in 12 instances, and mesocosm studies have been reported in only once until now. Advanced research was mostly evaluated at the microorganism level. But integrated analysis of nanotoxicity is required to research the interactions based of various species. Thus, our studies analysed the trend of microcosm studies on nanomaterials in water and soil ecosystems and suggested future directions of microcosm research of nanomaterials.

Recently, there has been a debate as to whether bioethanol should replace some portion of gasoline for fuels in South Korea, as energy security as well as climate change issues are rising as a significant national agenda. However, a considerable amount of subsidy will be required to compensate for the higher price of bioethanol-blended gasoline. In this context, government subsidy will obtain justification only when the positive social gains from consuming bioethanol for fuels can exceed the negative social costs. Through a nation-wide choice experimental survey, we examine if South Koreans have a positive value as well as non-linear preferences on substituting bioethanol for gasoline. The results reveal that the willingness to pay for purely domestic bioethanol-blended gasoline within 10% is about 52 KRW; Koreans have concave preferences on the blending ratio of bioethanol to gasoline. The turning point of the blending ratio of bioethanol was 6.5%. Also, we found inverse U-shaped curve between income and bioethanol choice probability and the turning point of the income was calculated as 250~299million KRW. Politically conservative propensity advocates uses of bioethanol blended gasoline, but awareness on bioethanol or more weights on environmental conservation have significantly negative effects on the choice of bioethanol. However, the design of the survey questionnaire is incompatible with the RFS of Korea and assumes orthogonality among the following four interrelated attributes: (i) domestic or offshore procurement of feedstocks in the case of domestic production, (ii) domestic production or import of bioethanol, (iii) the blending ratios, and (iv) the retail price increases. In addition, the results of model estimation and of model selection test are not definite. Hence, the results in this study should not be directly applied to the design of the specifics of the Korean RFS. Hence, the results in this study require cautions in applying to the design of the Korean RFS policy.
