| The occurrence of Marteilioides chungmuensis, a protozoan paramyxean parasite in the reproductive system of the Pacific oyster Crassostrea gigas, was observed at Gosung Bay, Korea. Seasonal variation in gonad development was investigated in a suspended cultured oyster population. Gametogenesis began in February and first-spawning was observed between mid and late June when surface water temperature reached 22 to 25degreesC. Spawning activity extended from mid June to late September, with 2 marked spawning peaks in June and August. Histological examination indicated that gonad development paralleled seasonal fluctuations in water temperature. Spawning in late June was partly associated with a sudden drop in salinity due to large freshwater inputs to the Bay... |

| The East Palaearctic and North Oriental species of the genus Psyttalia Walker (Hymenoptera, Braconidae, Opiinae) are reviewed. Three new species are described and illustrated: P. latinervis Wu & van Achterberg, sp. n. and P. majocellata Wu & van Achterberg, sp. n. from China, and P. spectabilis van Achterberg, sp. n. from Japan. Coeloreuteus formosanus Watanabe, 1934, Opius (Lissosema) proclivis Papp, 1981, O. (Psyttalia) subcyclogaster Tobias, 1998, O. (P.) darasunicus Tobias, 1998, O. (P.) cyclogastroides Tobias, 1998, Psyttalia extensa Weng & Chen, 2001, and Rhogadopsis longicaudifera Li & van Achterberg, 2013, are new synonyms of Psyttalia cyclogaster (Thomson, 1895); Opius (Psyttalia) ophthalmicus Tobias, 1977, and O. (P.)... |

| This paper examines the effects of the U.S.-Korea free trade agreement (KORUS FTA) on various sectors of the economy in the two countries using a general equilibrium model. Additional analysis focuses on the agricultural sector. Our analysis indicates that the increase in U.S.-Korea bilateral trade volume in recent years has been through intra-industry trade of high-technology products. Under the KORUS FTA, the bilateral trade volume would increase for virtually all the sectors, and GDP and social welfare would improve for both countries. However, producers of textile products in the United States and producers of agricultural and food products in South Korea would suffer from the FTA. This agreement could benefit U.S. agriculture, but the benefits... |

| The purpose of this paper is to simulate the proposed modality in market access and estimate its potential impacts on Korea's tariff profile. By accommodating a tiered formula for tariff reduction, the modality attempts to harmonize tariffs across products and countries. When no flexibility in tariff cuts is taken into account, Korea would face up to 68 percent reduction in tariffs in an average term (the baseline). The provision of sensitive products in which the tariff cuts are allowed to deviate from the tiered formula by two-thirds at a maximum is likely to bring about 11 percentage points of maximum tariff saving effects compared with the baseline case. Besides, Korea would be able to maximize savings in tariff reductions by 25 percentage points by... |

| The purpose of this study was to identify the factors influencing productive activities of the Korean rural elderly. Utilizing data from the 2004 survey "Living Profile and Welfare Service Needs of Older Persons in Korea," this study predicted the productive activities of the rural elderly. All of the ten predicting variables selected from the survey and literature review (age, gender, education, activity limitation, personal income, health, organization, family status, socio-economic status, and job) were found to have significant partial effects on such productive activities as paid work, care-giving and volunteer work. The following are major conclusions: The rural elderly women had more care-giving, whereas men had more volunteer work. Participation in... |

| Abolishing a nearly 50-year-old policy for rice price support, Korea adopted a new direct payment program in 2005. Making the transition to decoupled income payments has been governed by the need for operative and effective income safety nets and the WTO disciplines on domestic support. The program aims to deal with over-supply of rice while guarding against the threat of income insecurity. Integrated into a target price mechanism, the fixed and variable payments compensate part of farm income loss arising from adverse market conditions. Besides, the government launched a public stockholding measure to ensure food security. A review of previous studies highlights the fixed payment has no or at most minimal effects on production while the variable payment... |

| This paper aims to review the role of farm households and the agro-food sector in the economy of rural areas in Korea. It discusses definition of rural area, share of agricultural and agro-food sectors in Korean economy, the income situation of farm households and non-farming activities, and multiplier effects of agriculture in Korea. Rural areas mean Eup and Myeon, whereas Dong means urban area. Rural population in Korea has continued to decrease over the years. In 2005, 18.3% of total land area, or 1,824thousand ha, was used for paddy and dry fields. The share of GRDP of agricultural, forestry, and fishing sectors was about 10% in 1985, but dropped to slightly over 3% in 2005. Thirty seven percent of farmers have a second employment in the non-farm... |

| This paper is an overview of important findings regarding the ongoing evolution of Asian dairy markets based on a series of new economic investigations. These investigations provide systematic empirical foundations for assessing Asian dairy markets with their new consumption patterns, changing industries, and trade prospects under different domestic and trade policy regimes. The findings are drawn from four case studies (China, India, Japan, and Korea), as well as a prospective analysis of future regional patterns of consumption and a policy analysis of trade liberalization of Asian dairy markets. The overview distills the findings of these new investigations and integrates them in the earlier economic literature; it draws policy implications and... |
