This study is aimed at identifying the value of marginal products(VMP) of agricultural labor, capital and land. The resources are the major portion of input costs of agricultural projects. To appraise economic feasibility of agricultural projects, the real value of the resources would be estimated by VMP of the inputs rather than by distorted actual market prices such as rural wages, rent and interest. To convert the market wage rate into shadow wage rate, covertion factor of 0.90 would be appicable based on the study results. To evaluate the right of way and compensation, VMP of land is recommendable to apply in land pricing rather than actural land rent prevailing in rural area which has been underrated on account of labor shortage and difficulty of farming. Discount rate as a opportunity cost of capital should be applied 7-8% considering the VMP of capital and interest rate of foreign loan from IBRD and ADB. For the successful appraisal of the agricultural projects, the recommendation of this study would be applied in the future.

The existing most studies on the apartment sales prices have been limited to relatively small size apartment complexes and have not categorized the apartment complexes based on the number of households. Some of them uses the apartment-related indices such as regional value estimates, sales unit price, and view right values. In the case of Seoul Metropolitan Area, the size of apartment complex has been growing to the level of large complex over more than 1,000 households through new town development, redevelopment and reconstruction. People prefers to choose a large scale complex instead of small complex based on their perception that a large scale apartment complex provides more conveniences in living. The result of this analysis revealed that the variables chosen as important determinants of the hedonic price model for large scale apartment complexes were square meters of apartment unit, rent/price ratio, number of bays, distance to the nearest subway station, and heating system method. This means that the sales price of apartment unit will be higher as the square meters of apartment unit increase, as the rent/price ratio decreases, as the distance to the nearest subway station increases, and as the number of bays increase.

This is the re-arrangement of the 2004 Asia Nutrition & Dietary Supplement Conference organized by ABF(The Asia Business Forum) in Singapore, especially regulatory view of point of health functional foods for Korea, Japan, and China. Foods that may have health benefits beyond the traditional nutrients that they contain are often called 'Functional Foods'. The concept of functional foods has become popular in recent years, first in Japan and later in other countries, including the USA.

KFDA(Korea Food and Drug Administration) is the only authority body for approval, advertisement and claims for the Health Functional Foods in Korea. In Japan, the Japan Health Food and Nutrition Food Association controls the approval, regulate functional foods' advertisement and claims under the name of FOSHU (Foods for Specified Health Uses). In China, the State Food and Drug Administration(SFDA) is the only authoritative organization for the application, supervision and administration of health related products. Asia, especially Korea, Japan and China, is one of the leader in the vitamins and dietary supplement(VDS) market.

This paper deals with the questions: Are media user's activities labour? Or rent? These questions have provoked a debate in the critical media studies and Marx's theory. But it is not a matter of choosing either labour or rent. Even if user's activities could contribute to valorization, it needs some mediating process. Media Platforms-Google, Facebook, etc.-play a key role, and have to employ other forms of labour. Labour in media platform produces some capital commodities. In view of media platform, Smythe's audience commodity can be considered as capital commodity. Assertion in this paper expected to provoke new debate on media platforms and its labourer.

Due to a publicly owned resources, the overexploitation of the fisheries resources can result in externalities in the form of reduced future levels of yield. These problems can be theoretically improved through effective management of the fishery. The paper illustrates maximum sustainable yield(MSY), maximum economic yield(MEY) and F0.1 level of fishing mortality as the concept of optimal yield, and it theoretically shows that MSY is more appropriate for the optimal yield than MEY where prices increase even though MEY achieves the maximization of economic rent in a fishery assuming constant prices. And the paper presents several fisheries management tools and policies such as input controls, output controls and taxes. As the traditional approach to fishery management, input controls involve restrictions on the physical inputs into the production process(e.g. capital, time or technology) and output controls involve limits on the quantity of fish that can be landed. To introduce user cost into the harvest decisions of rent-seeking fishers, taxation, as a bioeconomic management policy of the fisheries, directly addresses the problems associated with the resource being unpriced. As most fisheries management plans, however, have increasing fisher income as an objective, taxes have not been introduced into any fisheries management policies despite their theoretical attraction.

The purpose of this study is to understand the factors that influence residents' satisfaction with their housing. Resident's satisfaction is mainly influenced by two factors - one that pertains to housing and the other as per characteristics of the individual. Housing-related factors include housing types, housing tenure types, and size of floor space. Individual-related factors include household income, size, and education level. This study shows how both factors influence residents' satisfaction. Residential satisfaction is affected by the type of housing tenure (own, chonsei and monthly rent) and housing (detached housing, apartment and multi-family housing). Residential satisfaction of home owners is greater than that of chonsei renters or monthly renters. Residential satisfaction of chonsei renters is greater than that of monthly renters. Satisfaction of apartment residents is far greater than that of detached housing residents or multi-family housing residents. There is no difference in residential satisfaction between detached housing and multi-family housing residents. As total household labor income, household member, and residential area increase, residential satisfaction increase. Residential satisfaction of countryside residents is greater than that of metropolitan residents.
