This study was practiced to survey food-borne bacterial aspects of Escherichia coli and Bacillus cereus etc. from 210 processed seasoned marine products in Garak fishery wholesale market in Seoul, 2009. Distributions of these bacterial isolates were 28 coliforms, 32 Bacillus spp., 71 Staphylococcus spp., 11 Listeria spp, and 10Enterococcus spp. in 157 dried squids, 23 dried file fishes, and 20 dried pollacks etc. respectively. Results in 16 kinds of antibiotics susceptibility test by disc diffusion method, special multiple drugs resistance patterns were NOR + LVX + CIP + SAM+ VA + S + TE + CF, SAM + C + VA, VA + S + TE, and VA + S in 9 E. coli strains, also,AMC + SAM + CF, SAM + CF, and VA + CF in 21 Bacillus cereus strains respectively. On the basis of the results above, many seasoned dried fishes had multiple drugs resistances, conclusively, we suggest limited guideline and special management on use of antibiotics in floating net cages of fishery farms.

서울시 가락농수산물시장에서 2001년 1-12월 수거한 총 742건의 수산물에서 장염비브리오균을 분리 동정한 결과 12.5%(93/742)의 검출율을 보였고, 월별로는 2월 7.14%(2/28), 5월 5.7%(3/53), 6월 5.1%(4/79), 7월 24.0%(18/75), 8월 48.0%(24/50), 9월 26.7%(23/86), 10월 11.1%(10/90), 11월 8.3%(6/72), 12월 5.7%(3/53) 등, 7-9월 검출율이 높아 하절기 장염비브리오균에 의한 식중독의 주요 원인균이 될 수 있음을 알 수 있었으며, 검체별로는 어류 8.3%(16/192), 패류 15.3%(37/242), 갑각류 8.5%(18/212) 그리고 연체류 22.9%(22/96)로 나타나, 연체류가 분리율이 비교적 높았다. 또한, 지역별로는 경기 23.2%(16/69), 경남 6.6%(9/136), 경북 33.3%(1/3), 전남 13.6%(31/228), 전북 14.7%(10/68), 충남 15.6%(5/32), 제주 11.8%(2/17) 그리고 수입수산물 8.8%(11/125)의 검출율을 보였다. 93주 가운데 66주에서 K-type 혈청형을 살펴본 결과, K24, K28이 갑오징어와 징거미에서 하나씩, K47, K53는 홍합에서, K34는 바지락살과 한치알에서, K42는 갑오징어, 꽁치, 대합 그리고 오징어에서 각각 확인되어 15.2%(10/66)의 동정율을 나타내었다.

The study aims to analyze economic of biogas plant in transition of recognition that waste resources has become renewable energy. The traditional investment valuation method using the NPV or IRR has a limitation in a sense that uncertainty of the future is not reflected. Hence, the purpose of this paper is to assess the value of the business by taking advantage of the real option. Biogas plant simulation is applied to the case of Garak Market using the binomial options among a variety of real options. With this analysis, it is assessed that operational expand option is the largest of the value of the binomial options.

It is possible to use pallet for forwarding as chinese cabbages and radishes are general large-scale trading items at the agricultural wholesale market though, however, most of these are forwarded as it have packed in net bags or in P·E bags. Thus, it is still hard for palletizing. The type of packing the product in the net bag makes it difficult for palletizing. It is not a stable shape enough and easily collapsed for pallet loading. Because of this collapsibility, the corrugated cardboard box is being used to enhance forwarding efficiency, but the existing corrugated cardboard box could be crushed easily by moist what is from the agricultural product’s property and it also could be squashed by the mass of the loaded box layers on itself. In contrary, the functional waterproof corrugated cardboard box is not collapsed through palletizing and it is efficient for product management with it’s ventilation function in respond to pre-cooling effect. Furthermore, because it has various functional shapes as the open type, the partition type and so on, it is effective for maintaining freshness of the product and standardizing the distribution of agricultural product. It is well-known that it is possible to introduce this box to cargo-works of agricultural product. Consequently, the recognition of main distributors about the pallet distribution of the chinese cabbage and the radish was apprehended in this study for activating mechanization of loading and unloading. The survey was conducted to the main distributors such as the forwarder, the auction dealer and the commission merchant with Garak-dong wholesale market as the center. The appropriate packing materials and problems of the existing method for loading and unloading were derived through the survey. Especially, it was focused on analyzing the difference of recognition between the subject groups for the way of using waterproof cardboard corrugated box to deal with the difficult product for packing in normal corrugated box because of the box’s absorption of moist from the agricultural product like a chinese cabbage and a radish. Total In the cases of the forwarders and the commission merchants, the net was highly responded as 45%, 74% from each groups for the best packing material for mechanization of distribution and the waterproof corrugated cardboard box was responded as 20%, 22% from each groups as much preferable than multi-stage wooden box. However, for the radish, the waterproof corrugated cardboard box was the best material as 56%, and the auction trader group supported it for 80%. So, the using the waterproof corrugated cardboard box for mechanization of distribution was negative for the chinese cabbage, but it was positive for the radish. The average was 2.42, the standard deviation was 1.24. The negative response(about 55%) was prevailing more than positive response( about 23%). It could be analyzed that even there was the positive recognition for using the waterproof corrugated cardboard box for the radish though the preference for low price of net bag in the chinese cabbage forwarding procedure. Still now, it seems that is a burden for using the waterproof corrugated cardboard box with high price. In the analysis on the recognition differences about using the waterproof corrugated cardboard box for the chinese cabbages and the radish between the forwarders and the commission merchants, generally the negative recognition was prevailing, but the forwarders( 2.696) were more positive for using the waterproof corrugated cardboard box than the commission merchants(2.145).
