Background: To confirm whether shellfish are suitable for consumption, the quality of seawater and shellfish in shellfish-producing areas must be assessed regularly. This study was conducted to evaluate the bacterial quality on the Changseon area, containing a designated shellfish-producing area, in Korea during 2011-2013. Result: Even though many inland pollutants near the area were identified, they showed no significant impact on the designated area and the shellfish therein. The concentrations of fecal bacteria in all the seawater and mussel samples from the designated area during the harvesting season were within the standards of various countries. Pathogenic bacteria were not detected in any of the mussel samples. In our previous study, the hazardous metal levels in all the mussels from the same area were also within the limits of different countries. Conclusion: The mussel products in this area are suitable for consumption based on fecal pollution, pathogenic bacteria, and also heavy metals.

Geophysical methodology using GPR(Ground Penetrating Radar) were applied both to the limestone producing area(Sambo Mine Company & Haksanri Area) and to Landfill area(Mureung Landfill Site). The investigation results resultant from both the limestone producing area(Sambo Mine Company & Haksanri Area) showed that there are a few events reflected from boundaries between caves and basement rocks. Those from landfill area showed that more complicated and small size events are found. These events could be from different electric characteristics of various kinds of composition materials in the landfill site.

Opening agricultural market expansion, reduced purchases through wholesale markets, expanding the influence large retailers of consumer's market such as changes in the distribution system to the farmer's market conditions are changing rapidly. Because of this, retailers of the scaled and chain-store operations was centered on distribution environmental changes of the consumer market place. In producing area due to changes in market conditions in the agricultural production of in producing area distribution organization and the size distribution can not be put off no longer challenge is imminent. If it do not raise forces banded together, the producer is bound to remain as the weak. To support the distribution of this production was introduced in 2000 enable the Activation Project of in producing area distribution. Recent in producing area Changes of Agricultural conditions in order to cope with the Small-scale farmers and small individual farmers are becoming Scaled and specialized. Also, is specific to each item and regional is showing aspects. Government support for Activation Project of in producing area distribution is greatly improved, but in terms of competitiveness on the market still is showing the limitations. The most common of these problems, the market response if in producing area producer's organization and scale of the problem. Equipped for the purpose of consumer market place responsiveness unreasonable propelled outward from the Painter-sized weakens the organizational power. also, Difficult to succeed organizational size is a dissolution or anything within a few years, farmers around the best producer organizations, such as deviation occurs is exposed to a variety of issues. In this study, previous studies refer to the recent changes in agricultural retail environment, background and needs of organization·scaled, Determine the status of the domestic in producing area organizations and derived Problems, look into Domestic and overseas of in producing area organization with best practices for enhancing the competitiveness of the proposed improvement are intended to. In the future, in producing area distribution policy would like to provide direction to the development. The results of the study showed the follwing : 1) enhance utilization and orrganized through the diversification of the agricultural Collection systems. 2) Scaled to achieve through Items of specialized a wide area marketing. 3) Management operating units, such as installation and operating that overseas the best practices " Comite Economique Agricole Regional 'Fruits et Legumes' de Bretagne". 4) To establish a support system that in producing area distribution organization model development for appropriate domestic. In particular, in case of domestic in producing area distribution organization, through the analysis of various case study that a successful organization and scaled. The process of the various challenges arising in organizational scaled and generalization, and by the way he goes about trying to overcome is required. At the end of the study's limitations and future research directions suggested.

The aim of the study was to analyze the spatial characteristics of the main producing areas of nontimber forest products. We analyzed the spatial aggregations of the main producing area and their changes using the Moran's I index. We found that 45% of nontimber forest products were significanty spatially clustered. Additionally, in five major products, we observed that the main producing area has expanded and the degree of aggregation has also strengthened over the last ten years. The results of this study can be effectively used for forest policies, such as determining the location and size of the distribution centers of specific forest products.

Objective: This study determined the optimal ratio of whole plant corn silage (WPCS) to corn stover (stems+leaves) silage (CSS) (WPCS:CSS) to reach the greatest profit of dairy farmers and evaluated its consequences with corn available for other purposes, enteric methane production and milk nitrogen efficiency (MNE) at varying milk production levels. Methods: An optimization model was developed. Chemical composition, rumen undegradable protein and metabolizable energy (ME) of WPCS and CSS from 4 cultivars were determined to provide data for the model. Results: At production levels of 0, 10, 20, and 30 kg milk/cow/d, the WPCS:CSS to maximize the profit of dairy farmers was 16:84, 22:78, 44:56, and 88:12, respectively, and the land area needed to grow corn plants was 4.5, 31.4, 33.4, and 30.3 ha, respectively. The amount of corn available (ton DM/ha/yr) for other purposes saved from this land area decreased with higher producing cows. However, compared with high producing cows (30 kg/d milk), more low producing cows (10 kg/d milk) and more land area to grow corn and soybeans was needed to produce the same total amount of milk. Extra land is available to grow corn for a higher milk production, leading to more corn available for other purposes. Increasing ME content of CSS decreased the land area needed, increased the profit of dairy farms and provided more corn available for other purposes. At the optimal WPCS:CSS, MNE and enteric methane production was greater, but methane production per kg milk was lower, for high producing cows. Conclusion: The WPCS:CSS to maximize the profit for dairy farms increases with decreased milk production levels. At a fixed total amount of milk being produced, high producing cows increase corn available for other purposes. At the optimal WPCS:CSS, methane emission intensity is smaller and MNE is greater for high producing cows.

The Agricultural Experimental Organizations[勸業模範場] in Suwon is Korea's first agricultural promotion facility. It was founded in 1906. This study aim to find the area and spatial composition of 勸業模範場. The results are as follows. When it founded, the Agricultural Experimental Organizations was operated centering on the main hall, and then since the pillage of national sovereignty in 1910, it was moved to the jurisdiction of the Japanese Government General of Korea and operated with the addition of the agricultural/forestry school. In 1913, the reductive egg production/distribution was moved from Yongsan branch to Suwon, and reductive egg producing site and female sericulture training office were installed in Suwon. It is supposed that at the time, the Agricultural Experimental Organizations was divided into the main hall-centered area, the Suwon agricultural/forestry school at the south side, and the reductive egg producing site and female sericulture training office even more down south. Since 1920, the agricultural/forestry school came out of the jurisdiction of the Agricultural Experimental Organizations, such that the Agricultural Experimental Organizations was left with only the main hall-centered area and the area with the reductive egg producing site and female sericulture training office. In this study, these two areas are referred to as 'the main hall area' and 'the sericulture area.

This study studied the characteristics of cultured oyster marketing in Sacheon Bay. The results of this study are summarized as follows. First, the GULDAE aquaculture is a unique production method of Sacheon Bay. Second, oysters in Sacheon Bay were low in production, but the price was more than 70% higher than in other producing areas. Third, profit is 12.5% higher and rate of return was 179.8%. Fourth, there were more out-of-market sales than other than other producing areas, and it is a bidding method. Fifth, the marketing cost was higher than the longline hanging aquaculture; however, the advantage of price offseted this point. Although the Sacheon Bay Oyster aquaculture is small, it was confirmed that it was a producing area with high profitability and a unique marketing form from other regions. Although the Sacheon Bay Oyster culture is small, it has been confirmed that it is a producing area with high profitability and shows a unique distribution form.

The purpose of this study is to identify the role of each party in relation to the contract farming of cabbage which is taking place under the contract between the local trader of agricultural produce that supplies raw cabbage to company "D," a manufacturer of kimchi, and the cabbage farm where the cabbage is grown, and to describe the changes brought by the contract farming to the agriculture of the contract area. As a result of the study, it was discovered that, while the farming of cabbage in the contract area used to be led by farmers, it is now increasingly being controlled by the local traders of agricultural produce. First, as the key player in the decision-making related to the cabbage farming in the main cabbage producing areas, local traders of agricultural produce are replacing the role of farmers by supervising the entire production process and controlling the overall cabbage farming in the contract area. Second, in the main cabbage producing areas, local traders of agricultural produce are becoming a key farming entity by carrying out functions that are comparable to those of farmers and playing a major role in the second half of the agricultural work at the farms in the contract area. This can be considered as the result of the balance between the demands of the local traders of agricultural produce who need to secure contract volume and manage the quality of their produce and the demands of the farmers in key cabbage producing areas who are facing difficulties due to the increase in the number of elderly farmers and a shortage of manpower.
