As the economy grows, there is a concern that the economic development causes a productivity reduction because of the service intensive growth. However, the economy of developed countries encounter with the productivity growth as their economy grows, which phenomenon called Baumol's paradox. Oulton (1999, 2001) find out the reason of Baumol's paradox in a forward and backward chain effects. So, this paper is aimed at verifying the theory of Oulton (1999, 2001). Moreover, we test the difference effect between a consumer service and producer service input using a dummy variable. We use the Input-Output Table (1990, 1995, 2000, 2005) that is offered by the Bank of Korea to accomplish the purpose of our research that is represented above. We find out that the Korea's intermediate producer service inputs cause a multifactor productivity growth. That result is matched with the Oulton (1999, 2001)'s theory. But, the intermediate consumer service inputs don't have a significant effect on a multifactor productivity. The result of verifying the effect of intermediate producer service inputs among industries shows that the effects on manufacture industries are less than other industries.

계산물은 고급단백질 식품으로 국민 보건향상에만 중요한 것이 아니라 축산업에서 차지하는 경제적 비중도 크다. 지난 10년간의 통계에 의하면 GNP 대비는 1% 정도에 불과하나 축산물 생산액 중 차지하는 비율은 무려 45.9%로, 한우의 25.8% 돼지의 22.1%, 유우의 3.8%에 비해 매우 중요하다. (중략)

생산, 가공, 유통, 그리고 소매로 이어지는 식품 공급의 흐름은 분업체제에서 복잡하게 뒤얽혀 있는 통합적인 형태로 변화해오고 있다. 그 변화를 뒤돌아보고 금후의 협동적 시스템 구축을 위한 과제를 찾아본다.

The laver has been cultivated long time ago in Korea. And traditional production system was changed to new system about 30 years ago. The new production system is understood the specialization of laver products, that is, originally individual fishery households made final laver products from raw cultured laver in sea working to dry working in land, but the new system was separated raw laver production in sea and dry laver production, which made final dry laver products by purchase the raw laver in land. This change has been increased laver production, 10 billion sheets in 2000's from 5 billion sheets in 1980's. And rapid production increase gave rise to some troubles on laver industry that is a serious drop in real laver prices, discord structure between raw laver producer and dry laver producer, stagnation of laver consumption, etc. Now Korea is the best laver production country together with Japan in world. Then we have to consider some schemes for the sustainable development of laver industry. One of such schemes is export enlargement of laver against world. The consumption of laver has been globally increased in recent. The other is the grading test problem of dry laver. Because the rapid increase of laver production caused to drop laver quality. Then we seriously have to consider the grading test of dry laver for high level quality production.

The purpose of this study is to estimate the extent of fisheries resource rebuilding and other economic effects on coastal gill-net fishery as a result of the Korean vessel buy-back program using with-without analysis based on methods estimating sustainable yields for all species caught by coastal gill-net fishery. Based on the results of with-without analysis, maximum sustainable yields (MSY) of all species caught by coastal gill-net fishery have been increased by the Korean vessel buy-back program. In addition, profits per vessel of maximum economic yield (MEY) of the species have been improved by the program. Further, yields and a producer surplus per vessel under an equilibrium of open access (OA) have increased because of the program. In detail, first of all, at the MSY level, the vessel buy-back program has led to about 21% fisheries resource recovery, and at the MEY level, it has led to about a 19% resource recovery. Secondly, at the MEY level and the OA level, the producer surplus per vessel has been increased by about 24% and 22% respectively by the vessel buy-back program.

Water is an essential resource for human survival. According to the OECD Environmental Outlook to 2050, rapid industrialization and a global population increase by approximately two billion will likely increase global water use by 55% in 2050. However, water depletion has been getting worse than before and has been happening more quickly, as Earth's water resources are limited. The present study proposes water management measures by using the virtual water theory which enables water consumption measurement and the confirmation and recognition of water scarcity problems, and will support the development of counter-measures. As a method for estimating the value of agricultural water, virtual water theory was used to calculate the amount of agricultural water input for domestic rice and to apply prices of agricultural water in the United States and China to Korean water prices. When the Chinese price was applied to Korean water prices, the value of agricultural water represented 0.3% of the Korean rice producer's price. When the US price was applied to Korean water prices, the value of agricultural water represented 1.6% of the domestic rice producer's price. The study exposes the percentage of the value of agricultural water in agricultural product prices, as well as how this scare resource may affect future prices. In the future, if there are water charges to effectively manage agricultural water, this study, which uses the virtual water theory, can be used as a preliminary research.

이 논문은 서울시 광고관련산업의 집적지 형성과정과 생산네트워크의 특성을 밝히고자 한다. 고차생산자서비스로서 광고관련산업의 서비스생산과정에서 관련업체와 생산네트워크가 중요한 기반임을 확인할 수 있었다. 인쇄광고관련업체와 방송광고관련업체의 집적지가 각각 도심의 충무로와 영동의 신사동지역에 형성되어 있었다. 이러한 집적지의 형성은 광고관련산업의 전반적인 유연적 전문화 과정과 연관이 있음을 알 수 있었으며, 관련 전문기능의 집적은 계속 강화되리라 예상된다. 광고회사는 주로 기획과 전략을 담당하고, 실제적인 제작 업무는 전무제작사들이 담당하는 공간적 분업과 생산의 네트워크화를 통해 광고하는 서비스가 생산되고 있었다. 그리고 각 집적지의 이득을 광고회사가 공간적 거리에 상관없이 충분히 활용하고 있었다. 결국 서울이라는 전체 공간이 함께 협력함으로써 서비스가 생산이 되는 모습을 보이고 있다. 이는 각 집적지내에서 관련 기능들이 서로 네트워크를 형성함으로써 네트워크의 이득을 활용하고 있으며, 또한 집적지 외부에 있는 기능이 공간적으로는 떨어져 있으나 다시 각 집적자와 네트워크를 형성함으로써 집적이득을 충분히 이용하는 국지적 집적효과가 아닌 지역적 집적효과를 활용하는 모습을 보이고 있었다.

In the suboesophageal ganglion of Bombyx mori, the diapause regulator producing cells which may give an information to the diapause factor cells were found by means of electron microscopy. The diapause regulator producing cells had larger granules (2000 to 5000 A$^{\circ}$ in diameter) than did the diapause factor cells which were partially surrounded by the formers. Highly electron-dense material of lysosome in the diapause regulator producing cells was observed in the diapause-egg producer but such lysosomes were not in the non-diapause egg-producer. It was found that many cytoplasmic granules fuse with lysosome, and smaller granules come out of lysosomes. Some implications of the diapause factor cell and the diapause regulator producing cell were discussed.
