It is worthwhile to know how the quality inspection is practised to assure the product quality for the export articles, and what problem is resulted from the current quality inspection system for the export articles. The aim of this paper is to survey the status of quality inspection system for the export articles and to design the quality inspection system for the export articles so as to not only solve the problems arising from the current system but also improve the product quality for the export articles. To find out the facts the survey is conducted by sending a prepared questionnaire both to the export industries and to the export quality inspection agencies authorized by the Ministry of Commerce and Industry. The export industries surveyed are selected to provide broad representation with respect to the type of industry as well as to the size of company. The survey shows that about 50 percent of the responding industries desire to discontinue the current quality inspection system for the export articles, and other 50 percent of them desire to continue it until all the export industries can make the best use of quality control techniques.

This study was carried out to examine the quality of Korean pork regular loins and hams which m exported in Japanese market. The samples were stored at 0${\pm}$1$^{\circ}C$(A, B companies) and 2${\pm}$1$^{\circ}C$(C, D companies). In analysis of Korean pork exported to Japanese market, the pork of A and D companies showed below 10$\^$6/CFU/$\textrm{cm}^2$ of total aerobic bacteria at 40 days storage and panels felt off-flavor after 40 days. Therefore the edible period will be 40 days through the analysis of microbe and sensory test in porks of A and D companies. The porks of B and C companies showed over 10$\^$6/CFU/$\textrm{cm}^2$ of total aerobic bacteria at 50 days storage and panels couldn't feel off-flavor in sensory test after 50 days. Therefore the edible period will be 50 days through the analysis of microbe and sensory test in porks of B and C companies. As the results, shelf-life of A and D companies will be 32 days and B and C companies will be 40 days from edible period by a factor of 0.8. In analysis of stored pork for export in Korean market, the porks of A and B companies showed over 10$\^$6/CFU/$\textrm{cm}^2$ at 40 days storage and C and D companies did over 10$\^$6/CFU/$\textrm{cm}^2$ at 30 days storage in analysis of microbe. The pork of A and D companies showed 10$^4$CFU/$\textrm{cm}^2$ but B and C companies did 10$\^$5/CFU/$\textrm{cm}^2$ at 50 days in coliform count. Therefore shelf-life of the pork of A company was logest and the next were B and C, but shelf-life of the pork of D company was 20 days, therefore it was even shorter than the others.

Heavy resposibility is placed on the veterinarian and the livestock and aquatic animal producers to observe the period for withdrawal of a drug prior to marketing to assure that illegal concentrations of drug residues in meat, milk, egg, fish and other animal foods do not occur. This is essential from a public health standpoint because levels of residues in excess of those legalIy permitted in edible tissues may produce injurious effects when consumed over a long time span. With greater use of animal drugs of chemicals required in production of food crops, livestock and aquatic animals, the possibility of human being continuously exposed to drug and chemical residues for a life time is unequivocally evident. Korean authorities concerned Ministry of Agriculture and Fishery and Ministry of Health and Social Affairs, have recenly made their own regulations to control chemical residues in beef, pork and chicken independently. Consequently, inspection for the chemical residues also have been or will be carried out by the two authorities concerned without any cooperations. It is undoubtfulI to have a single regulation and national residue program for control residual chemicals in animal foods and that the tolerance levels should be established in milk, egg, and freshwater fish. Besides, we have no complete standard methods to analyze the residual chemicals and the methods have not been evaluated their efficiency, precise, accuracy and limit of detection. In this paper, the analytical methods and national residue programs in foreign countries are introduced and discussed and the status of animal food safety in this country is also reviewed.

The purposes of this study were to develop value-added sauce (chili hot sauce) products with Korean advanced chili peppers (Capsicum annuum L.), to determine physicochemical characteristics of hot sauces, and to conduct a sensory evaluation of developed hot sauces. American chili hot sauce products were collected from the American local favorites, and were analyzed based on their compositions. The developed Korean hot sauce contained tomato (29.2%), onion (18.2%), sugar (11.5%), vinegar (10.9%), Korean chili peppers (11.0%), herbs, plum extract, and oligosaccharide, and it showed a higher overall acceptability, compared to that of the hot sauce samples. Its physiochemical analysis showed: salt $5.46{\pm}0.21%$, total acidity $6.04{\pm}0.04%$, pH $3.32{\pm}0.25$, and $^{\circ}brix$ $58.50{\pm}0.10$. This result suggests the possibility for developing a processed chili pepper products.

This study was carried out to investigate the changes in physicochemical, microbiological and sensory properties on vacuum packaged Yakibuda products for Export during storage at $4{\pm}1^{\circ}C$ for 40 days. Yakibuda, Japanese favorite meat product, were produced with three different pork cuts or tenderloin (T1), loin (T2) and ham (T3). The pH of all produce was tend to increased with increase in storage period. After 40 days of storage, pH of T2 was significantly (p<0.05) higher compared to other treatments. TBARS and VBN values of all treatments were increased with increased storage period. The water holding capacity ranged $81.41{\sim}92.20%$ in T1, $81.13{\sim}94.51%$ in T2 and $82.93{\sim}87.50%$ in T3. The shear force of T3 was higher than that of other treatments during whole storage time. The number of microorganism (Total plate counts, Escherichia coli, Lactobacilli spp.) were below 3.0 $log_{10}CFU/cm^2$ during the whole storage period. In sensory evaluation, the score of overall acceptability were above 5.5 point in all products. The storage properties of vacuum packaged Yakibuda could be maintained for 40 days at $4{\pm}1^{\circ}C$ storage temperature.

This study intends to construct scenic byway database and to examine and suggest social experiment of scenic byway. As basis work for the experiment of the scenic byway, we build database by using ITS standard node link management system. The DB includes scenic byway routes of Korea and Japan. The analyses show that the scenic byway in both nations consists of roads, reservation, road sign, vehicle number plate, and it was found that infrastructure and system are inadequate for scenic byway. These experiment can be effectively used for scenic byway in Korea and Japan as the basis data. The results of this experiment will be useful for plan and develop a scenic byway.

The world is currently confronted with regional conflicts among nations that seek to protect their territory. The associated counter-terrorism activities and international business flows can be increased through airworthiness-recognition tasks that are related to aircraft exports, dispatch troops, and overseas bases. It is important to establish airworthiness-recognition processes between foreign military authorities to minimize the potential for sovereign national positions and responsibilities. For this study, the military airworthiness recognition between recognition partners was surveyed to secure flight safety for the development and operation of aircrafts. The analysis of the U.S. and European Military Authority Recognition Questionsets (MARQs) in this paper introduces the rules, inspection capabilities, production process, and certification of the airworthiness authority. The regulatory activities, which are required by the Korea Military Airworthiness Authority (MAA) with respect to foreign MAAs, can be reduced by the implementation of the MARQ.

The microbial populations of exportable and domestic white ginseng powders, which have been problems in quality control, were higher than the legally-permissive level of microorganisms as $5{\times}10^{4}$/g in total bacteria and as negative coliforms. Various microorganisms contaminated in the sample were effectively decontaminated by gamma irradiation at below 10 kGy as well as ethylene oxide (EO) fumigation. The radiosens.tivity of microorganisms was the highest in coliforms, followed by molds and aerobic bacteria ($D_{10}$: 1.25 kGy). The good microbiological quality could be retained in white ginseng powders for more than 7 months of storage at $30{\pm}2^{\circ}C$ irrespective of relative humidities if products are prepared with a lower moisture content below 10% and treated by gamma irradiation at 5 to 10 kGy in an airtight packaging.

Eosinophilic gastroenteritis is a rare clinicopathologic entity of unknown etiology with a variety of digestive symptoms. The pathogenesis is poorly understood. Diagnostic criteria include demonstration of eosinophilic infiltration of the affected bowel wall, lack of evidence of extraintestinal disease, and exclusion of various disorders that could mimic similar conditions. The disease might involve any area of the gastrointestinal tract from the esophagus to the rectum, but the stomach and the proximal small bowel are most commonly affected. The clinical features depend on which layer and site are involved. We report the case of a 59-year-old male patient with a 3-week history of post-prandial vomiting with malnutrition and weight loss. An abdominopelvic CT showed a gastric outlet obstruction with diffuse wall thickening, as with linitis plastica. Three gastrofiberscopic biopsies showed chronic gastritis. We carried out a radical total gastrectomy with D2 lymph node dissection. The pathologic report revealed a mural type eosinophilic gastritis with a marked hypertrophic scar formation at the proper muscle layer. We report this case with a brief review of the literature.

Objectives: Although outbreak of MDR Tb has been a recent problem in western countries, it has been a longstanding problem in Korea. The poor outcome of MDR Tb is mainly due to poor compliance, high rate of side reaction of secondary drugs, and limitation in number of available drugs. Thus, to improve the outcome of MDR Tb, it is crucial to make individualized adequate prescription based on the knowledge of the patterns of resistance to each drugs in the community as well as the natural history. The purpose of present study is to evaluate the clinical features of Korean MDR Tb patients including patterns of drug resistance and success rate of treatment which was prescribed according to the sensitivity tests. Methods: Retroscpective analysis of 71 Korean patients with MDR Tb was made. All strains isolated from patients showed resistence to at least two first line drugs. Patients profile, previous treatment history, patterns of drug resistance, outcome of treatment was analysed. Initial treatment regimen was selected according to the previous treatment history and was modified according to the sensitivity reports. The regimen was composed to include at least 4 sensitive drugs when possible. Results: The patients showed resistance to 4.1 drugs on average. 90% of them were resistant to INH and RFP. Among 71 patients, 35 patients(49%) had cavitary lesions in CXR. Treatment outcome was analysed in 55 patients. 35 patients(67%) were improved after treatment and 18 patients(33%) showed treatment failure. 5 patients showed primary resistance. Treatment outcome could be evaluated in 4 of them and all showed improvement after treatment. 14 patients(20%) had to change their regimens due to drug side effects. The most frequent side effect was elevation of liver enzymes(6 patients). Others included dizziness, hyperuricemia, tinnitus, skin rash, GI troubles. More than 50% of side effects developed within 3 months. In repeated drug sensitivity test, the concordance rate of resistance to INH was 100% and RFP 98%. EMB, PZA showed 80% concordance rate. But in the other drugs, the concordances were less than 50%. Operation was done in 5 patient - 1 patients as a adjunctive means of chemotherapy -. In that case, negative conversion of sputum AFB was done. Conclusion: 2/3 patients of multidrug-resistant tuberculosis were improved by appropriate prescription and regular medication suggesting that more aggressive management and monitoring is indicated in multidrug-resistant tuberculosis.
