The subject of this study is limited to the market of producting and the analyzed the change of the supply structures, but the wide range of the study also contains the relationship present movement of consumption and the supply stuctures. To put it concretely, the present movement of the structre and the development of the market of producting are examined with the fisheries processing firms. The factors which dominate the structure of fisheries processing are; first, fisheries products as raw materials of processing; second, man-power; third, processing facilities and techniques; forth, a market where the products will be consumed. In particular, the conditions of supply of raw materials which are major factor have been worse and worse due to exhaustion of marine resources and so the capacity of fisheries production has been reduced. Furthermore, the conditions of manpower also are in trouble. Under the conditons, raw materials are imported largely and many companies try to make overseas enpansion for cheap manpower and raw materials. Particulaly, the relationship between consumption market and the structure of processing in a place of producton is analyzed newly. I try to show new logic that demands of consumption market are reflected strongerly to production with the development of consumption market and the rights of decision on the choice of raw materials and a processing item have been handed over to consumption market. In a word, I try to examined closely the new supply structure of fisheries products and the structure of consumption market through the analysis of the structure of processing in a place of production.

This study was performed to survey distribution of microorganisms and food-borne pathogenic bacterium in order to estimate microbiological safety in seonsik and saengsik. Total aerobic bacteria was detected over $10^5\;CFU/g$ in raw materials($4.3\%$) and products($35.7\%$) of saengsik. Coliforms were detected over $10^2\;CFU/g$ in seonsik products($27.3\%$) and in raw materials($4.3\%$) and products($35.7\%$) of saengsik. Cl. perfringens was detected in saengsik products($4.8\%$). B. cereus was detected in raw materials($12.5\%$) and products($18.2\%$) of seonsik and raw materials($13.0\%$) and products($23.8\%$) of saengsik. Concentration and detection rate of microorganisms in products were higher than raw materials. These results show some food hygiene problems but do not cause food poisoning because concentration of Clostridium perfringens and B. cereus were lower than $10^5\;CFU/g$.

The purpose of this study is to develop the algorithm applicable to the integrated production inventory model under quantity discount. To achieve this purpose, the integrated production inventory model which unifies the inventory problem of raw materials and the finished product for a single product manufacturing system is considered. The product is manufactured in batches and the raw materials are obtained from outside suppliers but some of the raw materials are discounted according to the purchasing quantity. The intergrated production inventory problem considered in this study is formulated by the non-linear mixed integer programming model, and the optimal solution is obtained by using the algorithm developed by Goyal. Then, the algorithm developed by this study is applied to the quantity discount problem, and the optimal solution is revised by this results. The quantity discount algorithm of the integrated production inventory model developed by this study gives a systematic procedure to obtain the optimum policy to minimize the total cost in any case. The numerical example involving 20 raw materials and 5 raw materials among them are discounted according to the purchasing quantity is given to verify the mathematical model and the algorithm developed in this study.

Exploitation of the ocean's deep water has brought humanity a wealth of treasures for centuries. Even so, it can confidently be forecast that the Ocean will be far more important to future generations than it has ever been in the past. Although many researchers endeavor to explore oceans, the ocean holds the crucial elements for maintaining a growing industrialized population in search of raw materials. This requires careful study and selection of innovations that will provide future generations and raw materials with an unlimited renewable and non-pollution energy and raw materials source with advantageous side benefits.

To provide a basic information on the chemical concentrations of different raw materials used in mushroom cultivation, the raw materials were collected from 13 Flammulina velutipes, 14 Pleurotus eryngii, and 8 P. ostreatus farms and analyzed to calculate moisture contents, pH, total carbon(T-C), total nitrate(T-N), total phosphate(T-P) and 13 different cations. In our results, the C : N ratios of cotton seed meal, beet pulp, and corn-cob were 6~17, 12~29 and 56~127, respectively. Depending on the companies which process these materials, the range of C:N ratio of soybean curd residue was approximately either 8~9 or 14~17 with wider range of C : N ratio of the raw materials imported from other countries without the detection of heavy metals. In this study, the formula was provided to calculate the composition of mixed media for mushroom cultivation based on the ingredient chart of different raw materials.

This study proposes a plan to construct an integrated platform that reduces manufacturing costs and efficiently produce by integrating the systems of main producers, production subcontractors, and raw material subcontractors for the production of food packaging containers. The production plan of food packaging containers and raw materials is established in real time between the main producers, production subcontractors, and raw material subcontractors in consideration of the demand characteristics of each product. It establishes basic information that all processes from the production planning stage to the forwarding stage of the product are linked to each other. The progress of each producer of interlinked processes is shared in real-time to improve productivity and quality of food packaging containers and raw materials and reduce manufacturing costs. By monitoring the system of the main producer and the production subcontractor in real time, the production of food packaging containers is performed in a timely manner, thereby improving productivity. The application of the plan-do-check-action (PDCA) process, which includes planning, execution, evaluation and improvement in the production operation processes of the main producer, production subcontractor and raw material subcontractor, enables improved production compliance rate. The contents of the main producers, production subcontractors, and raw material subcontractors are managed in real time, then a converged production management system is established through the platform proposed in this study to ensure timely supply and demand of raw materials without delay in ordering.

In the management activities of head office in supporting franchisees in domestic food-service enterprises, the raw material supply plays a positive role to support franchisees' operation activity and it comes into conflict with them at the same time. In this paper, I have tried to find out the relationship between raw material supplying and the satisfaction of the franchisees by experimental research in order to research the route of head office's raw material supplying. To sum up the results, it was found out there is no meaningful relationship between the raw material supplying and the franchisees satisfaction (intention to renew the agreement), It indicates it would be more effective for the franchisees to buy the raw materials from the suppliers developed by the franchisees except some key materials in order to reduce the conflicts with the franchisees.
