Synthetic detergents and surfactants are in widespread usage as household and industrial detergents. Potential human toxic hazard arises following percutaneous absorption or oral ingestion of solution residues from kitchen and feeding utensils, fruits, and vegetables and contaminated water supplies. A toxicological investigations was performed with the synthetic detergents and surfactants [linear alkyl benzene sulfonate (LAS), ${\alpha}$-olefin sulfonate (AOS), sodium lauryl sulfonate (SLS), sodium lauryl ester sulfonate (SLES)］, In acute toxicity, agents were administered subcutaneously into ICR mice. In acute study, after lowering of spontaneous motility, respiratory failure, death appeared, vomitting was often associated with salivation and or retching. No sex difference was observed in LD$\sub$50/ of mice. In subacute toxicity, agents were administered orally into SD rats. Body weight increase was suppressed and there was no adverse effect on food and water consumption. The weight of organs were not changed by agents as compared with control group. No specific change was observed in biochemical and hematologicalor data.

The study was conducted to establish the HACCP model for chicken dishes (deep-fried sirloin chicken, chicken and potato in red pepper paste, smothered chicken) sewed in 3 different elementary school lunch program during 2002. the hygienic conditions of the food facilities and environment were at the lowest limit of normal grade. Workers' practices should be improved: sanitary handling and proper holding of foods and utensils. Kitchen layout should be remodeled for separation of soiled and clean work areas. pH values of all items were over 6.0 which required careful attention. (omitted)

This study aims at efficiency of kitchen management by adoption of a systematic central kitchen and conversion of conventional kitchen to convenience kitchen at ' H ' restaurant. First, integrated menu control of banquet buffet functions became more competitive with quality menu and eventually brought about guests satisfaction. Second, systematic central kitchen made possible standardization and mass production through simplified production line. Efficiency through quick service and shortened preparation time was realized, and food materials were recycled effectively at the same time. Integrated ordering lowered purchasing price and built an efficient cost control system. Third, conversion of conventional kitchen to convenience kitchen and strengthened central kitchen system facilitated agreeable work conditions and optimal work flow with butcher's and even sauce making utensils. Fourth, integrated supply system of buffet menu and sauce from western restaurants saved about 520 million won of labor costs. Last, one integrated kitchen out of two was easier in sanitation control with pleasant restaurant space. Sharing kitchen facilities and equipments also saved about 30% of maintenance fee. Power, water, and gas were also saved and eventually curtailed overall expenses.

The purpose of this study was to investigate the effect of the multi-level marketing(MLM) on consumer by examing the degree of damage and the consumers's satisfaction with MLM as well as the overall realities of MLM including the degree of the recognition and the distribution route of the commodities. We analyzed 256 cases which had experienced with MLM among 430 questionnaires collected. The resulted are as follows. 1) Consumers showed a lack of knowledge about MLM regardless of experiencing it. And they were recognized positively with the quality and the availability of the commodities. Expendables such as kitchen utensils and cosmetics were the most favored articles. 2) Transactions with no written contract were the most frequent damage to the consumers, followed by no price-tag and the marketer's refusal of exchange or refund. 3) When we compared the degree of consumer's satisfaction with MLM to the ordinary distribution in terms of the price, quality of goods and the service offered, the consumers were satisfied with the quality of the commodities, though their whole impressin of MLM was not so much favorable.

Overall migration through epoxy layer coated wood was investigated to estimate the coating thickness satisfying the regulatory limit. As an index of overall migration, KMnO$_4$ oxidizable extractives by the food simulant water solution was used. Migration pattern in interest range could described by a simple diffusion model and the temperature dependence of the permeability index could be explained by Arrhenius equation. The thickness of epoxy coating greater than 0.004 mm was analyzed to be required for satisfying the regulatory guideline.

Foodborne diseases are serious problems throughout the world, because new pathogens have emerged. Nowadays many students eat school lunch provided by school lunch program. They are threatened by pathogens transmitted by foods. Many school children became victims of foodborne diseases. Most foodborne outbreaks were caused by mishandling foods at food serivece establishments. Temperature control is the most critical point of keeping the foods safe. In order to prevent foodborne diseases in schools, the managers in charge of school lunch program and officials in charge of food safety of local health department try to make sure that foods are out of danger zone of temperature. Prevention of cross sontamination, and sanitization of raw foods and utensils are also emphasized by school lunch program managers and health officials.

This study examines the background and necessity of the product certification (KS) and the system authentication (ISO 9000), and their characteristic so as to compare and analyze the possibility of interaction of product certification and system authentication. It tries to suggest an efficient operation system as an integrated management system and analyzes the certification case of K, a manufacturer of kitchen utensils. We believe that the study will help companies minimize their expenses and efforts to establish, operate, and maintain the corporate standard system. In addition, to effectively achieve our goal, we have also made a study of both literature and case and suggested technical guidance to get integrated management system certification. By these methods, we analyzed the effects and problems that come with the introduction and application of the integrated system of product certification and system authentication in order to set up a system to fit to the mechanism of Korean companies. Moreover, we have suggested the model of integrated operation and the benefits that come after acquiring certification.

Pediatric dysphagia comes from disturbances in swallowing process, which has 'preparatory phase', 'oral phase', 'pharyngeal phase', and 'esophageal phase', and mainly the causes are neuro-muscular discoor-dination. It is necessary to recognize clinical manifestation if they have accompanied organic disorder and diagnose accurately. Videofluoroscopic study evaluation is a valuable method to find out abnormal swallowing mechanism at each phases. Treatment should be diagnosis specific, and multidisciplinary team approach is desirable. We can use various behavioral techniques to facilitate normal swallowing mechanism including conditioning of oral and pharyngeal structures, bolus manipulation, postural compensation, and adaptive feeding utensils. Important point is that the diagnosis and treatment for pediatric dysphagia should not be delayed because children are under development.
