세계적으로 천연가스는 환경적, 정치적, 지역적인 이유로 중요한 에너지원으로 부상하고 있다. 우리나라에서 천연가스는 액화천연가스로 수입하고 있으며, 석탄과 원전을 대체하는 연료나 원료의 활용에서 액화천연가스는 증가하고 있다. 우리나라는 천연가스를 수입에 의존하고 있기 때문에 공급에 대한 안정성분석이 중요하다. 따라서, 본 연구에서는 우리나라 수입구조의 위험도 분석을 통하여 공급리스크를 줄이고 안정적인 공급과 수요를 위한 방안을 제시하였다. 공급위험도를 감소시키기 위해 한 국가로부터의 수입 집중도를 낮춰야 하며, 가스공급안정성 지수 (gas supply security index, GSSI)가 낮은 국가의 수입비중을 낮추고 상대적으로 안정적인 국가인 러시아로부터 수입을 증가시켜야 한다. 또한, 수입국가의 수를 늘리거나 안정적 공급이 가능한 국가와의 관계 유지는 우리나라 수입가스의 공급안정성지표 (total gas supply security index, TGSSI)에 긍정적인 영향을 줄 것으로 분석되었다.

2000년~2011년 동안 제조업의 생산액 변화에 기여한 요인과 요인별 기여도를 투입산출 구조분해분석으로 한국과 일본 간에 비교하였다. 분석결과에 따르면, 제조업 생산 증가에 가장 크게 기여한 요인은 한국의 경우 수출인 반면에 일본에서는 기술변화이다. 한국 제조업 생산 증가에 대한 기술변화의 기여도는 상대적으로 미미하며 감소하고 있는 것으로 분석되었다. 한편, 국내최종수요는 한국에서는 수출에 이어 제조업 생산 증가의 두 번째 기여요인인 반면에 일본에서는 제조업 생산 감소의 가장 큰 기여요인이다. 특히, 두 국가 모두에서 중간재와 최종재의 국산화율은 감소하여 제조업 생산 위축의 주요 요인으로 작용하였다. 결과적으로 한국 제조업의 수출의존적 성장을 재확인하였으며, 이러한 수출의존도가 강화되고 있음도 확인하였다. 하지만, 과도한 수출의존도는 점점 심화되고 있는 세계경제 변동성과 불확실성을 고려할 때 한편으로는 한국 제조업의 지속적 성장에 장애요인이 될 수도 있음을 의미한다. 따라서 모든 기여요인이 균형적으로 성장에 기여하는 것이 중요하며, 특히, 상대적으로 저조한 것으로 분석된 기술변화의 기여도를 높이기 위한 연구개발 및 기술혁신 강화와 중간재 및 최종재의 국산화율 높이기 위한 노력이 더 요구되는 정책적 시사점이 있다.

Consumer's concerns over beef safety are increasing according to resuming U.S. beef import. And a few beef producers have converted into organic beef recently. This organic beef must have taste, nutrition and safety that consumers demand for. Korean organic beef should be gone on sale at the shop under direct management of producer's organizations or the special shop for Environmentally friendly products. So they should win consumers' confidence for beef safety and transparency in producing and marketing process.

A Linear Approximated Inverse Almost Ideal Demand System, suggested by Eales and Unnevehr, is estimated with monthly data set of Korean fruits consumption. LA/IAIDS consists of 6 demand equations which correspond to domestically produced Hanrabong, overwintering mandarin, strawberry, melon and tomato with imported orange. The results indicate that price and scale flexibilities are negative, as expected. And the significance is that a 10% increase in imported orange quantity is associated with 5.5% declines in the price of Korean Hanrabong while the price of other fruits is minimally affected. In addition, the estimate of scale flexibility of Hanrabong (-2.96) is much smaller than any other fruit. Hanrabong farmer might be in the face of deficit operation as a consequence of the substitution effect if orange would be imported in accordance with the Korea-U.S. free trade agreement.

The purpose of this study was aimed to investigate the historical tends of population growth which has reflected direct effect of the ratio of food self sufficiency in Korea between the year of 1910 and 1980. Author divided the whole years between 1910 and 1980 into five different periods ; colonial period from 1910 to 1945, post colonial period from 1945 to 1950, Korean war period from 1950 to 1955, post Korean war period from 1955 to 1960, fast economic growing period 1960~1980. The ratio of national food self sufficiency has been profoundlly affected by dual factors ; rate of population group and increment of GNP which reflect the national economic development. Total food production never reached the level of population growth ratio in Korea. As a result food demand and supply has shown imbalaced condition which leads to import foods from outside contury to compensate food shortage. The increment of GNP sharply cut down the cereal consumption. The consumption of fish, milk, eggs and meat reflected to increase since 1970.

The purpose of this study is to identify demand and methods of projection, including to prove the variables affecting the fluctuation of visitors and to analyze the relationship between these variables in National Park. Statistical analysis method (Multiple Linear Regression Analysis, ANOVA, and Model diagnostics) was carried out by computer program SAS/pc. 13 variables (1. Total Population, 2. Per Capita PDI, 3. Employment Ratio of S.O.C. & others, 4. NO. of Passenger Car, 5. Length of Roads, 6. Leisure Expenditure of Farm Household, 7. Leisure Expenditure of Urban Household, 8. Price Index, 9. NO. of Bus, 10. Exchange on Dollars, 11. Export, 12. Import, and 13. Visitors in National Park) had been used to this study. The scope of time period is during the last 17 years (1970-1986). The results were as follows; 1) Participation depends only on the specific characteristics of the economic factors (Price Index and Leisure Expenditure of Urban Household). These factors are the importance factors directly affecting the participation of visitors. The statistical Model for projecting the visitors in National Parks is the function of "Visitors in National Parks (thousand)=14915+0.210311*Leisure Expenditure of Urband Household (won)-157.835619*Price Index(1985=100)" 2) The external factors affecting the participation depends upon the interelated features of availability and accessibility (NO. of Passenger Car, Length of Roads, and NO. of Bus) of recreation resources or sites, and the economic factors (Per Capita PDI, Export, and Import). These factors are the factors indirectly affecting the participation of visitors. 3) The participation depends on the specific characteristics of demographic factors (Total Population and Employment Ratio of S.O.C. & others). These factors are the factors indirectly affecting the participation of visitors. 4) The unexpected fluctuation of yearly visitors depends on oil shock or inflation (1971, 1973-1974, 1979-1980), promulgation of national emergency decrees (1971-1972, 1974-1975, 1979-1980), and national events (assassination of president Park's wife, Madame Yuk in 1974 and president Park I 1979).

The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.

In this paper, fishery economics is reviewed to extend a basic opportunity for developing new fishery economics and to evaluate the effects of the import liberalization on the fish trade structure of Korea. The principle outline of extensions emphasis to realize the modern fishery problems based on fishery economics and develop the practical methodology in order to analyze the impacts of the import liberalization on the fishery and fishermen welfare. During the process of export - oriented industrilization, the role and position of fishery in the economy is changed dynamically. When faced with the imperative of the role and position of fishery in the economy, fishery economists and domestic policy makers must decide how to organize themselves for solving fishery problems under the new regime in the import liberalization on the fish trade. Fishery problems impacted by the new regime can not be solved by fishery itself but be solved by the centralized efforts of all contributors in national views. Therefore the new systematic analytical methodology must be develop and the traditional fishery economics must be related to the regional development strategy and fishery sociology as subsidiary theories specialized. Due to the impacts of the import liberalization on the fish trade structure, fishery economists face with radical changes in the domestic fishery : a place of the resources harvest to place of the combination resource harvest and its demand, a fishing as a resource exploitation to a fishing as a resource management, a traditional small scale costal fishing to a modernized and scaled fishing, fishery using the given natural resource itself to fishery as technology intensive industry, and a food supply industry to a welfare indusry based on the regional and economic resource and social environment. As these changes, fishery and its community's regional and economic resource and social environments as multiple roles of the regional economic development are emphasized in fishery economics under the new regime in the import liberalization on the fish trade. Furthermore, domestic policy makers and administrators in a public sector must realize the above radical changing trends in fishery and understand a social and economic environment in fishery and develop a new fishery structure focusing on the fishing system and the fishery laws. As this point, they make efforts to improve and develop fishery as a food supply industry. Japan, for example, has a non - governmental organization to conflict the problem of international fishery such as a movement of a civil environmental protection. Also fishermen in Japan already realized conservation and pollution problems in fishing as fundamental issues of human being.

These days, international air-logistics demand is getting bigger and bigger by increasing in trading volumes of export and import of Asia. It makes the air logistics of stakeholder to invest in air logistics facilities and information systems for meeting the growth of air transportation. However there are some problems that the efficiency of investment is not good by duplicately investing in information systems and moreover not compatible with each other because the stakeholder is investing in individual information system and air logistics facilities instead of constructing the integrated infrastructure. In this paper, we investigated the export, import, and transshipment process of air logistics to simplify air logistics process through the RFID(Radio Frequency Identification) application and the 4PL system.
