Two hundred seventy-four microorganisms were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains and their microbial diversity was analyzed. The specimens of macrofungi were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains. Eunseong and Dogok in Gyeongsangbuk-do, for selecting the heavy metal-degrading strains. Soil was also collected from same location. Contents of heavy metals (Cd, Cu, Pb, Zn, Ni, Cr, and As) were determined spectrometically in fruiting bodies of forty eight wild macrofungi specimens with soils. When the analysed their transfer factor from soil to fruiting body, Amanita volvata have the highest transfer factor of cadmium and arsenic. And Mycena pura showed the highest in mercury, Marasmius pulcherripes in zinc, Laccaria laccata in nickel, and Collybia confluens in chrome. When compare the population of mushrooms between the contaminated mines and Mt. Chiak as the healthy area, Genus Russula and Collybia were collected both area, but Leucocoprinus, Coprinus, Suillus, Lepiost, Gyroporus, Lepista, Microstoma, Stropharia, and Agrocybe were only in the contaminated mine area.

Jeju soybean industry is not competitive in areas of food-safety, quality, price, and bargaining power. Also, the processing products of soybean are simply-processed product. They are short of diversified product. The size of processing company is very small. The purpose of this study is to review and suggest programs for the construction and management of a network among farmhouseholds, agricultural cooperatives, manufacturing companies, related research institutes, and the local government, which are integrated vertically, horizontally and systematically. Jeju soybean cluster consists of production system, research & development system, industrial-support system, practical technology-support system, and center of operation. This system will help farmers get stable sales market & income. Also, It will help farmers produce the production of environment-friendly agricultural raw products.

The objective of this study was to compare the farm efficiency of members of cooperative firms with that of non-members in Korea. Data were collected from 27 farms members of three cooperatives and 13 non-member farms, based on the managerial achievements of 1999. For the analysis, the data were divided into three different farming types: type I and II of member farms and non-member farms. Economic analysis were implemented using DEA(Data Envelopment Analysis). Major findings was as follows. Total average technology efficiency was 0.782, which implies that there still remains 21.8% of improvement possibility. Among the three types, type I showed the highest technology efficiency of 0.9055, while type II and non-member farms showed 0.7670 and 0.7171, respectively. This means that these farms have relatively high potential improved. Also, comparing technology efficiency by dividing into pure technology and scale efficiency, all type of the farms exhibit a higher pure technology efficiency compared to scale efficiency. Therefore, to improve current technology efficiency, farms need to focus more on pure technology efficiency improvement. Meanwhile, profit analysis based on farm size indicate that most of the farms demonstrated the increasing-return-to-scale, which means it is necessary to extend the farm size to improve technical efficiency. Type I member farms achieve higher profit and efficiency than other two types and relatively higher producer prices through introducing cooperative sorting, grading and packing. Also, these labor saving technologies increased farm size.

This study is to analyze location conditions for erosion control dams to be constructed in Chungcheongnam-do, Daejeon Metropolitan City, Chungcheongbuk-do and Gyeongsangbuk-do in order to establish proper conditions for erosion control dams in the future. 199 sites where erosion control dams are expected to be built in 2010 were chosen and investigated in terms of 12 factors including basin area, basin slope, and landslide risk. The results showed that erosion control dams for Chungcheongnam-do and Daejeon Metropolitan City are mostly impermeable gravity dams mainly composed of concrete. In contrast, Chungcheongbuk-do and Gyeongsangbuk-do are increasing the number of permeable or compound erosion control dams. Basin analysis at planned erosion control dam sites showed that at least 44.5% of the total area has high landslide risk. Gyeongsangbuk-do had the largest basin area for erosion control dam sites at 157.3ha, followed by Chungcheongbuk-do at 64.4ha and Chungcheongnam-do at 54.8ha. Analysis of sand deposits in the Chungcheongnam-do erosion control dam built in 2010 confirmed an average deposit of 971.8m3. The sand deposit capacity and amount of sediment control for erosion control dams have a very low correlation with basin area or flow path slope, and this needs to be addressed in future sand deposit capacity designs.

Local assemblers of agricultural products perform important distribution functions such as providing sales outlets, labor forces, market information, and financing, forward contracting, farming, physical distribution, and etc. However, their business activities are not transparent and producers are not effectively protected from unfair practices done by local assemblers. In order to enhance transparency and to increase effectiveness of governmental policies, local assemblers, which are mostly private management, should be organized as corporations. In order to organize corporations, the government should emphasize the importance of education and should provide corporations with governmental funds for improvement of agricultural distribution. Corporations should be developed to marketing cooperatives in the long run, and are requested to form their federations. It is also necessary to have transparent forward contracting system by local assemblers. In order to have transparent system, producers and local assemblers are guided to use standard contract forms and to operate offices handling unfair trade practices by local assemblers. We also need a place to exchange forward contracts, which can be developed to a futures market in the long run. In summary, local assemblers of agricultural products, which are mostly private management, should be developed to corporations and be operated by a transparent manner in order to protect agricultural producers and increase efficiency of trading.

This study was conducted to identify key success factors of the Agricultural Cooperative Federation. We classified the divisions of regional agricultural cooperatives into high performers and low performers to investigate differences in environmental stability, resource capacity, resource flexibility, differentiation strategy, and low-cost strategies between high and low performers. Empirical analyses revealed that high performers are superior to low performers in resource capacity, resource flexibility, differentiation, and low-cost, but there was no difference in environmental stability between high performers and low performers. Internal factors including resource and strategy attributes affect business performance, but external factors such as environmental attributes do not. Moreover, resource flexibility generates the broadest gap between high performers and low performers. These results indicate that resource flexibility is the key factor leading to success of organizations with greater competitors because it enables them to overcome their disadvantageous competitive position in size and resources through complete exploitation of resources across divergent business areas owing to its flexibility. Our contribution is that we draw the key success factors of the Agricultural Cooperative Federation through an empirical approach.

The currently implemented Positive List System, sales manager training, and pesticide sales record systems focus on the safety of determined pesticide use, but the proposed agrochemical pharmacist (AP) system aims accurate diagnosis and reasonable prescription. In this study, 81% of famers claimed expert assistance for purchasing and applying pesticides, and 42~86% of sales managers insisted on the strengthening expertise in diagnosis and prescription. In the institutionalization of AP, a special implementation guideline is essential to embrace the present sales managers with long experience. Sales managers of commercial and agricultural cooperatives recognize the qualifications of agrochemical pharmacists as a strategy to differentiate themselves from competitors, and increase sales through market positioning of "pesticides prescribed by trustworthy agrochemical pharmacists", not sales managers anymore.

To advance the effectiveness of the current Hanwoo improvement system, we developed a general simulation that compared a series of breeding schemes under realistic user circumstances. We call this system the Integrated General Model (IGM) and it allows users to control the breeding schemes and selection methods by manipulating the input parameters. The Current Hanwoo Performance and Progeny Test (CHPPT) scheme was simulated with a Modified Hanwoo Performance and Progeny Test (MHPPT) scheme using a Hanwoo Breeding Farm cow population of the Livestock Improvement Main Center (LOMC) of the National Agricultural Cooperatives Federation (NACF). To compare the two schemes, a new method, the Simple Hanwoo Performance Test (SHPT), which uses ultrasound technology for measuring the carcass traits of live animals, was developed. These three models, including the CHPPT, incorporated three types of selection criteria: phenotype (PH), true breeding value (TBV), and estimated breeding value (EBV). The simulation was scheduled to mimic an actual Hanwoo breeding program; thus, the simulation was run to include the years 1983-2020 for each breeding method and was replicated 10 times. The parameters for simulation were derived from the literature. Approximately 642,000 animals were simulated per replication for the CHPPT scheme; 129,000 animals were simulated for the MHPPT scheme and 112,000 animals for the SHPT scheme. Throughout the 38-year simulation, all estimated parameters of each simulated population, regardless of population size, showed results similar to the input parameters. The deviations between input and output values for the parameters in the large populations were statistically acceptable. In this study, we integrated three simulated models, including the CHPPT, in an attempt to achieve the greatest genetic gains within major economic traits including body weight at 12 months of age (BW12), body weight at 24 months of age (BW24), average daily gain from 6 to 12 months (ADG), carcass weight (CWT), carcass longissimus muscle area (CLMA), carcass marbling score (CMS), ultrasound scanned longissimus muscle area (ULMA), and ultrasound scanned marbling score (UMS).

We hypothesized that supplementing finishing diets with palm oil would promote adipogenic gene expression and stearoyl-CoA desaturase (SCD) gene expression in subcutaneous (s.c.) and intramuscular (i.m.) adipose tissues of feedlot steers. Eighteen Angus and Angus crossbred steers were assigned to three groups of 6 steers and fed a basal diet (control), with 3% palm oil, or with 3% soybean oil, for 70 d, top-dressed daily. Tailhead s.c. adipose tissue was obtained by biopsy at 14 d before the initiation of dietary treatments and at 35 d of dietary treatments. At slaughter, after 70 d of dietary treatment, tailhead s.c. adipose tissue and i.m. adipose tissue were obtained from the longissimus thoracis muscle. Palm oil increased plasma palmitic acid and soybean oil increased plasma linoleic acid and ${\alpha}$-linolenic acid relative to the initial sampling time. Expression of AMP-activated protein kinase alpha ($AMPK{\alpha}$) and peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) increased between the initial and intermediate biopsies and declined thereafter (p<0.03). SCD gene expression did not change between the initial and intermediate biopsies but declined by over 75% by the final period (p = 0.04), and G-coupled protein receptor 43 (GPR43) gene expression was unaffected by diet or time on trial. Soybean oil decreased (p = 0.01) $PPAR{\gamma}$ gene expression at the intermediate sample time. At the terminal sample time, $PPAR{\gamma}$ and SCD gene expression was less in i.m. adipose tissue than in s.c. adipose tissue (p<0.05). $AMPK{\alpha}$ gene expression was less in s.c. adipose tissue of palm oil-fed steers than in control steers (p = 0.04) and CCAAT enhancer binding protein-beta ($CEBP{\beta}$) gene expression was less in s.c. and i.m. adipose tissues of palm oil-fed steers than in soybean oil-fed steers (p<0.03). Soybean oil decreased SCD gene expression in s.c. adipose tissue (p = 0.05); SCD gene expression in palm oil-fed steers was intermediate between control and soybean oil-fed steers. Contrary to our original hypothesis, palm oil did not promote adipogenic gene expression in s.c. and i.m. adipose tissue.

The study was conducted to indentify systematically current marketing structure and markeiing efficiency of major cash crops such as red peppers and garlics. That various data and information have been used to analyze the problems related, some of them have come from secondary sources, but major parts of real circum stances were primarily obtained from the scheduled field survey. Some of valuable facts and consequences stemmed from the research can be summarized as fellows: First of all, the commercial rates of peppers and garlics produced by sample farms were 87.5 percent and 69 percent, respectively. On the other hand, annual handling volumes per marketing firm of those two crops were on the average estimated into 51,000 kyun(about 600gr) for peppers and 20,000 hundred bulbs of garlic. As seen physical losses over the entire marketing channels of each crop, it was approximately calculated in 14.7 percent of peppers and 21.1 percent of garlic, respectively. Secondarily, it was found that marketing chanells of these crops are very diversified and complex. However, the five-staged chanell is typical: i.e., from producers to local consigners, to local carry-out merchants, to consigner-wholesales, and finally to retailers. Thirdly, it was also estimated that gross marketing margin, marketing cost and profit based on average grade of peppers were 56.1 percent, 22.6 and 33.5 percent, respectively, having 43.8 percent of farmer's share, and those of garlic 38.9, 17.1, 21.8 and 61.1 percent, separately. To the end, it seems that current collective bargaining power of farmers' cooperatives is virtually weak compared to free individual marketing firms in terms of bssiness volumes and quantity handled over the year.
