This study aims to explore the benefits and extension's role with farmers' markets in USA. This study was conducted by literature review and case study. They help establish connections between consumers and food producers, provide an additional income source for farmers. and in general, serve as a tool for community development. First, from education to advocacy, from research to advising, extension educators have multiple roles to play in promoting the growth of farmers' markets. Second, it is essential that extension engage others who are interested in seeing the markets succeed and create opportunities for such groups to make the market unique in their given communities. Third, extension promotes farmers' markets through the creation and dissemination of how-to publications. These publications typically include tips about having a market establishing a prominent and easily accessible market location, and offering a sufficient product variety to ensure consumer satisfaction. Fourth, efforts by extension offices are already paying off for consumers, vendors, and communities. Involving those who will purchase as well as produce the foods sold at who will purchase as well as produce the foods sold at farmers' markets should diversify the audience extension educators reach. Fifth, extension educators can aid in this effort by encouraging farmers' market vendors to diversify their of offerings and to produce and sell value-added products. Sixth, many extension offices offer guides to the direct marketing venues in their counties, such as farmers' markets, pick your own operations, roadside stands, and community supported apiculture farms. Once such a guide is produced. extension educators can distribute it at workshops and inform local media about the guide so that they can publicize it. Seventh, extension educators should seek to involve those groups who can collaborators could include community economic development organizations, consumer groups, churches, food banks, land preservation organizations, school, farmers' organizations, and other community groups. Eighth, extension educators can also contribute to the improvement of existing markets by offering workshops for vendors in business management, advertizing, marketing, bookkeeping, personnel management, and food preservation. Ninth, farmer's market also provide an opportunity for extension to have face-to face communication with farmers. Tenth, if farmers' markets are well managed, these markets can provide economic, nutritive, educational, social and psychological benefits to venders and the community.

The data on milk yield of 1837 healthy dairy cows of different genetic groups raised in Central Cattle Breeding and Dairy farms, Savar, Dhaka for the period from 1978 to 1992 were analyzed from first to 6th lactation. The mean (SE) milk yields of 100 days, 305 days, total lactation and total life time ($928{\pm}48.6kg$, $2,188{\pm}201.81kg$, $2,661{\pm}385.46kg$ and $11,134{\pm}2,916kg$) respectively, were in pure bred Friesian found to be highest among all genetic groups. The corresponding means in indigenous cows, $334{\pm}12.92kg$, $946{\pm}64.44kg$, $635{\pm}16.31kg$ and $3,934{\pm}402.21kg$ were the lowest. Among the $F_1$, $F_2$ and $F_3$ cross-breds, the $F_1$ half bred Friesian showed the highest performance in milk yield. The half bred Friesian in successive generations yielded low milk. Similar trend was obtained incase of cross-bred with other breeds such as Jersey, Sindhi and Sahiwal. From the over all results, it can be concluded that the performance in respect to milk yield of pure bred Friesian and their $F_1$ half bred with indigenous and Sahiwal were superior over the $F_2$ or $F_3$ cross-breds between Fresian and any other breed irrespective of proportion of blood. The performance in respect to production of indigenous local cow was found to be almost similar with that of Sahiwal breed.

This study was conducted to analyze the current management status of green tea processors in two regions (Hadong-gun and Boseong-gun) in Korea and to suggest directions for the development of the green tea industry based on an understanding their difficulties in management. This study showed that the number of green tea farms and the cultivation area had decreased, while the average unit sales price of green tea in Boseong-gun was approximately three times higher than that in Hadong-gun. Also, this study found that Hadong-gun mainly provided green tea products to wholesalers, whereas Boseong-gun sold it directly to the local retail stores targeting tourists, and this results in generating relatively higher unit prices. Meanwhile, we discovered that both regions had difficulties in management which were caused by the demand for low delivery unit costs from large corporations and small food companies. Therefore, in order to develop the green tea industry in both regions, the size of green tea fields and the scenery satisfaction should be improved to draw more tourists and boost tourists' intention to revisit. In addition, it is necessary to enhance guidance and accessibility of related tourist sites, to expand green tea experience activities, and to improve product satisfaction by developing various goods. By inducing more tourists in these ways, it could change the sales type of green tea from wholesale to retail and help activate the management of green tea processors.

The final site of offshore wind power plant should be decided by comprehensive examination of various conditions such as wind resource, sea depth, geology, grid connection, social circumstance and environmental issue. Wind condition is typically regarded as the most important factor because wind energy increases in proportion to wind velocity and it directly relates to the amount of power output, efficiency of power plant and profitability. Advanced countries in the offshore wind power sector such as Denmark, UK and Germany, they are analyzing wind resource accurately by installing the meteorological mast in the ocean in order to get the optimal type of wind turbine and maximum generation efficiency. Also, it is made much of designing offshore power plant on the basis of actual measurement by met-mast and those wind farms have a chance to get the loan with reduced interest rate in project financing. In Korea, the HEMOSU-1 is installed in the ocean around Wido island to analyze wind resource of test bed of 100MW offshore wind power on october last year. This paper deals with the design and construction procedure of the first met-mast in Korea and also shows the site characteristics of test bed. Therefore, this paper will give useful information to local governments and private business sector who are trying to construct offshore wind farm and it can also be a good reference for the following projects of meteorological mast in near future.

Background: Deficiency of macro and micro-minerals in the ration of dairy cows adversely affects growth, milk production and reproduction efficiency. It is essential to examine mineral concentrations in feeds offered to dairy cows in practical farms. Methods: Two villages from each taluka were selected at random for taking representative samples of feeds, forages and hair. Within the village, help was sought from village milk producers and district animal husbandry officer for identification of 4 to 5 farmers and collection of representative samples. All the samples were processed and analyzed for chemical composition as well as major macro and micro-minerals, using Inductively Coupled Plasma-Optical Emission Spectrometer. Results: Ca content in wheat straw (0.29%), crushed maize (0.02%) and wheat bran (0.12%) was found to be below the critical level (0.30%). The P content in concentrate ingredients was high (0.26-0.96%), but low in dry roughages (0.06-0.12%). Cereal straws (0.14%) and grains (0.12%) were deficient in Mg. Feeds and forages were found to be adequate in K (1.50%). Cereals straws were found to be deficient in S (0.11%). Greens were good source of Cu (12.02 ppm). Wheat straw was found to be low in Zn (18 ppm), but high in Mn (225 ppm) and Fe (509 ppm). Local grasses and azolla green were found to be rich source of Co (>1.00 ppm). Se (0.63 ppm) was present in appreciable quantities in most of the feedstuffs. Conclusions: From the present study, it was apparent that the feeds and forages available in the state of Jharkhand may not meet the requirements for Ca, P, Mg, Cu, Zn and Co in order to sustain a milk production of ~10 kg/day. Therefore, it is necessary to supplement these deficient minerals through area specific mineral mixture in the ration of dairy cows for improving productivity and reproduction efficiency.

Changes of gonadal morphology and mRNA expression patterns of vitellogenin were investigated in Siberian sturgeon Acipenser baerii (Chondrostei) during its early gonadal maturation period. Early differentiations and morphological transitions of both ovaries and testes appeared to occur actively until the age of 3 years, however from then on, the maturation patterns to full maturity were largely gender-dependent, in which males showed a faster progression of maturation than did females while females experienced a steady-state progress with a lagged interval before entering the final maturation. Expression of vitellogenin mRNAs are closely correlated with transitional patterns of gonadal appearances. In both females and males, hepatic mRNA levels of vitellogenin exponentially increased in the earliest interval (up to 1-year-old). However, in subsequent periods, vitellogenin expression in females continued to increase with age, whereas in males, the expression stabilized at a younger age. Nevertheless, at the age older than or equal to 7-year-old, fully matured individuals showed a quite low level of vitellogenin expression in both females and males. Collectively, results from this study could be useful as a fundamental guideline to address the gonad maturation of this sturgeon species, which is helpful for making practical decisions about farming practices and management for caviar production on local sturgeon farms.

이 논문은 베트남 중부고원지대 커피변경지역의 중심 지역인 닥락(Dak Lak) 성을 대상으로 커피변경지역의 형성과 그 구조변동을 탐구하였다. 기존의 연구들이 글로벌커피시장의 영향에 주로 초점을 둔데 비해, 본 연구에서는 변경적 특수성 및 베트남의 시장경제체제로의 전환과정에 이루어진 개혁조치들이 닥락의 커피생산지리 발달에 어떤 영향을 미쳤는지에 더 주목을 하였다. 이를 위해 국영회사의 생산시스템 변화, 커피농가의 토지보유과정에서 나타난 변경적 특성과 전환경제적 상황을 밝히고자 하였다. 이 연구는 닥락의 커피생산지리 발달과정을 세계커피시장의 영향측면에서만 접근해온 기존 연구들이 상대적으로 소홀한 측면을 제시함으로써 커피변경지역 이해에 일정한 기여를 하였다고 본다.

The structural and environmental characteristics of typical pig houses in different growth phases were surveyed and analyzed. Based on the data for thirty nine selected farms in four provinces, Jeonbuk-do, Jeonnam-do, Gyeongbuk-do, and Gyeongnam-do, in the southern provinces, Korea, the goal is to eventually establish standard pig houses of sow and litter, nursery pigs, and growing-finishing pigs. The survey included farm scale, production specialization, structural dimensions of the houses and their ventilation systems, cooling and heating systems, and floor and pit systems related to manure collection. The survey showed 90∼98% of growing-finishing pig houses adopted the sidewall curtain systems. The sidewall curtain systems, although popular, is not well insulated which leads to excessive heating costs in winter. Regarding flooring and manure collection system of the house, 23∼35% of growing-finishing houses installed scraper systems with concrete-slat floors in Gyeongsang provinces while 52∼78% did in Jeolla provinces. The cause of a large variance in flooring between tow regions could not be academically pinpointed, rather it could be attributed to the advice of neighbors who leads local pig production circle. A general trend toward enlargement and enclosure of pig houses for all growth phases was gaining popularity in most regions in recent years. A steady shift to multisite operation from continuous operation was also observed to prevent a disease transfer. The structural design of a standard pig house with its environmental control systems including ventilation and heating/cooling system was suggested for further validation study. In-depth analysis of the survey data is presented in the Results and Discussion section.

To investigate provincial seed Potato Production farms, a Preliminary survey on the local population of the aphids was made in Sulchon alphine area, Mooju-Goon, Chollapuk-Bo where the climatic conditions were almost same as those of Taegwanryong Kangwon-Do, where Alpine Experimental station is located. This area stands from 650 to 900 metres above the sea level and divided three location of A. B, C, by altitude. A stands at 900 metres above the sea level. B at 750 metres and C at 650 metres. A and B divided three points: Al, A2, A3, and Bl, B2, B3- and divided four points-Cl, C2, C3, C4- at the distance of 300 metres apart each other. The traps were operated from July 21 to October 31, 1969. Otherwise, the traps established at Suwon (inland) and Taegwanryong where Alpine Experimental Station. A total of some 70 species including five virus vector species were identified. The Numbers of species at 10 locations, Suwon and Taegwanryong are as follows; Al-34, A2-38, A3-29, B1-25, B2-26, B3-29, C1-27, C2-14, C3-32, C4-37, species (Table 1), Suwon-49 species (including 5 virus vectors species), Taegwanryong-22 species (including 4 virus vector species). The aphids are shown in Table 1 and the Vectors are as follows: 1. Aphis gossypii Glover 2. Aulacorthum solani (Kaltenbach) 3. Lipaphis erysimi (Kaltenbach) 4. Myzus persicae(Sulzer) 5. Phorodon humuli (Schrank) Numbers of vectors versus total aphid at each locations, including inland (Suwon) and alpine area (Taegwanryong) where Alpine Experimental Station are as Fig. 1. Of a total 8,902 aphids, 6,400 $(80\%)$ were Tetraneura sp. The number of aphids devoid of the number of Tetraneura sp. are as follows; (Numbers means mean of each locations) A; 215. B; 115, C; 176 and Suwon; 2,952, Taegwanryong; 247. Densities of aphids at the locations is lower :han those at Suwon and Taegwanryong. And density of vectors at the locations, at ranged from 11 to 37, is love. than those at inland (Suwon; 197) and alpine area (Taegwanryong; 90). Thus, this area is suitable for seed potato production as Multiplication field.
