This study analyses the macroeconomic effects of the direct payment system (DPS) for environment-friendly agriculture in Korea. We utilized the applied general equilibrium model (AGE model) for the general agricultural sector as well as the environmentally-friendly agricultural sector. We considered several scenarios based on various direct payment amounts to measure and analyze economic impacts. Scenario 1 considers the current direct payment system. Scenario 2 examines an additional 5% increase from the direct payment amount in scenario 1. Scenario 3 reviews an increase of 10% in direct payment amount while Scenario 4 considers an additional increase of 15% compared with Scenario 1. Lastly, scenario 5 examines a 20% increase in direct payment amounts compared with scenario 1. In addition, the baseline considers conditions prior to the introduction of the direct payment system. The simulation analysis results show that capital formation, production volume, and labor productivity increased in the environment-friendly agricultural sector. In contrast, employment in the environment-friendly agricultural sector decreased. The price of environment-friendly agricultural products following the introduction of the DPS remain consistent with the price of environment-friendly agricultural product before introducing the DPS. This results from price elasticity of supply and demand are inelastic, and there is no change in the income of consumers during the analysis period. However, additional research is necessary for improvement of the model using complementary statistical data for the environmental-friendly agriculture sector.

Electronic security system is composed mainly of electronic-information-communication device, so system technology, configuration and management of the electronic security system could be affected by the change of information-communication environment. This study is to propose the future prospect on the development of technique for electronic security system through the analysis of the trend and the actual condition on the development of technique. This study is based on literature study and interview with user and provider of electronic security system, also survey was carried out by system provider and members of security integration company to come up with more practical result. Hybrid DVR technology that has multi-function such as motion detection, target tracking and image identification is expected to be developed. And 'Embedded IP camera' technology that internet server and image identification software are built in. Those technologies could change the configuration and management of CCTV system. Fingerprint identification technology and face identification technology are continually developed to get more reliability, but continual development of surveillance and three-dimension identification technology for more efficient face identification system is needed. As radio identification and tracking function of RFID is appreciated as very useful for access control system, hardware and software of RFID technology is expected to be developed, but government's support for market revitalization is necessary. Behavior pattern identification sensor technology is expected to be developed and could replace passive infrared sensor that cause system error, giving security guard firm confidence for response. The principle of behavior pattern identification is similar to image identification, so those two technology could be integrated with tracking technology and radio identification technology of RFID for total monitoring system. For more efficient electronic security system, middle-ware's role is very important to integrate the technology of electronic security system, this could make possible of installing the integrated security system.

There is a growing demand to access the broadband internet while on the very fast move. In order to meet these users needs, much research has been made for providing the broadband internet and HDTV services via satellite broadband internet systems even at top train speeds above 200km/h. In this paper, economic analyses on the satellite broadband internet services for KTX are to be reviewed. Broadband internet to trains in Europe are investigated, and Boeing cases for planes are also examined. In the first step, system configuration which is composed of a hub, terminals, satellite, and gap fillers for the tunnel areas has been proposed. A terminal includes a ultra-fast high gain antenna installed on the roof of the train, and APs inside the coaches. Secondly, cost estimation on the capital expenditures as well as operating expenditures has been performed in the proposed configuration. From the european and Boeing cases, demand and tariff are postulated, consequently, service revenues are derived on the scenario basis. Thirdly, estimated costs and derived revenues make up net present value and internal rate of return in each scenario. Finally, conclusions and contribution of this study are presented.

정부는 그린홈 100만호 보급 사업에서 연료전지의 보급 목표를 2010년 200대 2011년 300대, 2012년 500대로 결정하였고 이에 따라 2012년까지 누적 보급대수가 1000대에 달할 전망이다. 본 연구에서는 현재 상업화 되어있는 국내업체의 1kW급 가정용 연료전지 시스템을 2009년에 도입되는 것으로 가정하여 경제성평가를 수행하였다. 분석의 편의상 2009년 서울 지역 난방면적 $100m^2$을 기준으로 전제하였고, 대표가정의 전기와 열수요는 CES 소형 열병합 사업 타당성 분석 프로그램(GS파워, 2006)을 활용하여 구했다. 비용의 경우 기존 보일러의 설비가격은 60만원이며 연료전지시스템의 설비가격은 1200만원이다. 다만 연료전지의 고가 소모품인 스택은 2007년 발간된 한국에너지 기술연구원의 신재생에너지 경제성평가 보고서를 인용하여 스택의 수명은 5년, 교체비용은 1000만 원이나 5년마다 30%의 비용 하락을 전제하였다. 또한, 연료전지시스템의 수명을 20년으로 가정하였으며 할인율은 5.5%를 가정하였다. 한편, 가정용 연료전지의 최적 운전방안을 찾기 위해서 기존 설비를 이용한 비용과 전기추종운전, 열추종운전의 시뮬레이션을 수행한 뒤 세가지 결과를 시간대별로 비교함으로써 최적의 시간대별 운전방식을 선택하는 복합추종운전의 비용을 분석하였다. 시뮬레이션결과, 기존 설비 이용 시 에너지 비용은 1,934,864원으로 분석된 반면 연료전지를 이용한 전기추종은 1,123,691원, 열추종은 1,180,425원, 복합추종은 1,121,174원으로 계산되었다. 한편 편익면에서는 복합추종운전시 813,690원의 편익이 발생하는 것으로 분석되었으며 B/C ratio의 결과는 0.405로 현재로서는 연료전지 시스템이 경제성이 없는 것으로 분석되었다. 따라서 정부는 연료전지의 보급목표와 민간 주도의 자생적인 시장형성을 촉진하기 위해서 단순 설치 보조금 이외에 연료전지시스템과 스택의 비용을 획기적으로 저감 시킬 수 있는 기술개발을 촉진하는 정책 병행이 필요해 보인다.

우리나라의 방송콘텐츠 시장은 2012년까지 연평균 성장률 3.5% 수준에 머무를 것으로 전망되고 있다. 원인으로는 콘텐츠 산업의 높은 파급효과에도 불구하고 영세한 제작환경 및 유통구조로 인해 양적/질적 측면에서의 낙후성을 벗어나지 못하는 것을 들 수 있다. 이는 경쟁 활성화를 가로막는 규제제도, 방송통신 플랫폼 사업자와 콘텐츠 제작자간 불공정 거래, 콘텐츠 제작자의 영세성 등에 기인한다. 이러한 우리 방송 환경을 고려할 때 신디케이트 도입은 성숙되지 않은 콘텐츠산업에 새로운 동력을 공급하는 계기가 될 것이다. 이러한 신디케이트 중 '온라인신디케이트'라는 것은 방송콘텐츠 유통전문기관을 설립함으로써 방송통신콘텐츠 판매창구를 개발하고, 제작사의 이익을 보장하며, 수요자에게 안정적으로 콘텐츠를 공급할 수 있다. 뿐만 아니라 국내외 시장 개척을 통해서 보다 확장된 창구화 효과를 거둘 수 있고, 현재의 변화된 방송환경에 맞추어 체계적이며 안정적인 공급과 판매를 통해서 우리나라 방송통신콘텐츠 산업 발전에 크게 이바지 할 수 있을 것으로 기대한다. 또한 방송통신콘텐츠 제작의 활성화와 유통구조의 개선은 전 세계를 대상으로 글로벌콘텐츠를 판매할 수 있어야 함으로 국제적 유통망 구축이 필수적이라고 할 수 있다. 그러므로 온라인신디케이트는 국제적 유통망구축에 효과적이며 결국 유통과 제작, 제작과 유통이 상호간 높은 관련성을 의미한다. 향 후 프로그램의 제작은 해외의 수출시장 파악이 우선이다. 그 후 국내 프로그램의 유통 성공여부를 가름하고, 해당 국가의 유통시장을 면밀히 분석할 필요가 있으며, 필요하다면 현지 유통사 및 제작사와 협력관계를 유지할 필요가 있다. 최종적으로 성공가능성을 타진하여 현지 유통사를 인수하는 것이 위험 부담을 크기 때문에 이러한 과정을 통해서 글로벌 유통기업을 만들어야 하나, 설립은 막대한 자금이 필요하므로 이러한 '온라인 유통공사(신디케이트)의 설립'은 처음 시작해야 하는 위험 부담을 줄이는 지름길일 것이다.

In Korea, there are 1,474 thousand pumping wells nationwide which account for about 12% of total water use in 2012. As much as 39 hundred million tons of groundwater were used while 333 hundred million tons of total water were supplied in 2012. Because the water management authority projects that water demand will exceed supply by 2021, the authority is planning to extensively expand groundwater use in accordance with economic feasibility. Using the basic frameworks of cost-benefit analyses of the World Bank and the US Environmental Protection Agency (US EPA), the objective of this study is to examine the costs and benefits of the expansion of Korea's groundwater extraction through pumping wells. We conclude that the BC ratio of the groundwater pumping wells is 2.98. This signifies that the benefits are 2.98 times higher than the costs. The benefits include use and non-use values of pumping wells while the costs include the installation and maintenance of new wells, in addition to the restoration and pollution costs of abandoned wells, as well as fees for water quality tests, etc.

Today seafoods, such as fisheries and clams, have become an important part of our diet. But processing and storing these perishable seafoods for a long period of time present a serious problem. Only a few years ago, the seafood consumption was minimal. However, an improvement in our diet has enabled us to enjoy seafoods more often than before. Moreover, the recent trend toward the concentration of the popuration to the metropolitan area and the improvement in the standards of living have accelerated a change in our food consumption pattern-preference for the convenient foods over time consuming cooking. Judging from these changes, we can easily predict that the demand for the covenient, dried seafoods will rise sharply in the coming days. The development for an innovative and attractive way to package and market these products are on the way. Research and development of the distribution channel and package design of the dried seafoods will offer a wide array of opportunities to increase the sales volume of the dried seafoods. In addition, by associating the image of Pusan, as a prime oceanic city, with the dried seafoods on the package will certainly draw the attention of many prospective consumers. Consequently it will make the dried seafoods special products of Pusan, and eventually contribute to the prosperity of the city.

Generally, the generation methods of cooling energy are electric air conditioning (EAC) and gas air conditioning (GAC). The EAC system is caused by increasing peak power during summer. Because the electric energy has a characteristic of non-storage, the peak electric load has been issued social problem annually whether the facility to supply is enough or not. Another way to supply cooling energy, GAC system is worked by gas energy. The absorption chiller and gas engine heat pump have been commercialized for cooling. However, the total capacity of GAC is much less than EAC and it almost depends on EAC for small market. This paper described the status of cooling energy consumption in domestic and expected the cooling energy to be consumed by electric and gas energy up to 2024 year. And also the benefit of GAC was analyzed with the case of its expansion and it was aimed to give background to fit the GAC policy.
