  • Product distribution and consumption in the military is difficult due to unique contracts and supply systems. It is difficult to change suppliers immediately when quality problem is encountered. Due to these special circumstances, the quality of products must be thoroughly controlled. Sesame oil is used to increase the taste and nutrition of food, but it is more expensive than other cooking oils. Oil producers may blend other cooking oils with sesame oil to make higher profits, so it has become important to identify good and bad products. In this study, pure sesame oil and blend oils were compared by analyzing their smell, taste, chemical components, and near infra-red spectra to determine quality differences between them.

  • The number of visiters to Bukhan Mt. national park, generation quantity of solid waste and collection system were researched to consider a counterplan for the pollution control of the national park and study for developing the effective treatment of solid waste was tried through the proximate analysis of each component containing. Results obtained in this study were summerized as follows; The great part of visitors go on an excursion to the Bukhan Mt. national park during July and August and also, the solid waste was generated nearly a half of the total amount at the same period. The major collection facilities in the national park were waste basket and incineration box. But the incineration box was too large in volume and very far in distance, and its collection period was irregular, so it was cause to the congestion of solid waste and bad smell and dirty. Therefore, to complete collection of solid waste, we must set up the waste basket which able to find within 40~50m from the origination place of solid waste and induce the visitors to throw the solid waste. It was obtained as moisture content: 48.5 wt%, volatile solid: 28.4wt%, fixed solid: 23.1 wt%, lower heating value: 1,320kca1/kg from experimental analysis of solid waste. According to this analysis, the incineration operation is possible, but the generation quantity of solid waste was too small to construct incineration plant for heat recovery. It was found that it is suitable for the aerobic composting by mixing with the night soil which generate in the national park after the recovery of resources such as metals, glasses and plastics.

  • The purpose of this study was to investigate attitude and behavior of eating and purchasing seafood in relation to eating pattern at the household level among Korean housewives. Analysis data from 676 housewives in Korea were collected with self-administered questionnaires. The results were as follows: Seventy-three % of the respondents answered that they liked seafood dishes for their taste, good nutrition and health benefit in order, but 3.2% disliked seafoods because of their bad smell, cooking difficulties and high prices. In comparison with the meat dishes, seafoods were considered superior to meat in nutritional value(49.9%), health aspect(46.4%) and taste(42.4%) but seafood stuffs were evaluated inferior to meat in the aspects of preparation process(43.9%), sanitational problems(40.4%) and higher price(35.2%). The favorite fish cooking methods of housewives turned out to be grilling, stewing, eating as raw fish, braising and frying in order. The 74.7% of respondents evaluated that their family preferred seafood dishes, but 37.2% of the subjects prepared seafood dishes 1-2 times a week followed by 3-4 times a week(24.0%), 2-3 times a month(19.6%), once a month(7.4%) and more than once a day(5.3%). The frequency rate of seafood preparation showed significant differences according to the monthly income of the household(p<0.05), the higher the income, the higher the frequency rate. As for the difficulties in preparing seafood dishes, cumbersome processes before cooking(45.4%), high price(10.4%) and sanitational problems of distribution(9.9%) were indicated showing significant differences among the age groups of the subjects(p<0.01). These findings revealed that younger generation housewife group is the major target in promoting seafood consumption at household level. We suggest to develop convenient sale packages and continuing education programs with information about easy handling and preparation of seafoods for the promotion of home cooking.

  • As a waste management tool, the prohibition of landfilling of food waste has enforced since 2005. the composition of municipal solid waste (MSW) has changed dramatically. In this study, MSW generated from a small city collected once a year in 2004, 2005 and 2007, to qualify the characteristics of MSW before and after implementation of the tool. The prohibition of landfilling of food waste dramatically reduces food waste in MSW to 5.5 weight %, and on the other hand results to increase papers to 50.6 % and plastics to 22.6 %, The bulk density lowers to 50 %, which newly propose the necessity of volume reduction and incineration of MSW to ensure efficient transport and disposal. As water content of MSW reduces to 15.9 %, lower heat value of MSW after prohibition of landfilling of food waste increase to 3565.6 kcal/kg. Mitigation of bad smell and waste leachate with lower contaminants are recommendable as a kind of positive effects benefited by the tool.

  • This paper studies the conservation treatment of Lady Shim's costume, which was excavated in Jecheon Province in 2012. There were the significant problems, which were encountered in the treatment of the costume ; First the Jeogoris were transformed during the excavation, Second fibers were seriously deteriorated, Third most of the fabrics such as Chusa were readily deformed. To overcome these problems and to secure stability in the conservation treatment, we decided to alternate between two different washing methods ; dry cleaning by n-hexane and wet cleaning by water. The costume shape was recovered by steaming and by swelling with Hanji(Korean traditional paper). The combined cleaning method proved to be relatively efficient and stable. In addition, the shape of Chusa was well preserved by dry cleaning.(using n-hexane also solved the problem of bad smell after washing with organic solvents.) The effects of the conservation treatment on the excavated costumes could be seen in the change of Lab color difference. Washing made the distribution of Lab color difference narrower, which may suggest that the impurities on the fiber was removed by washing. In addition, the value of L was greater than a-value and b-value after the treatment. This result indicates that the change of value represents the change of color difference by cleaning.

  • We investigated the change of symptoms and preventive behaviors before and after the Asian Dust events among indoor workers (teachers) and outdoor workers (taxi drivers and bus drivers). On February 2004, we recruited 195 taxi drivers, 135 bus drivers and 93 school teachers. Symptoms and behaviors related the Asian Dust events during 1 week were questioned by self administrated questionnaires. We surveyed pre-event and post-event. The symptom were not changed in bus drivers during the events. In taxi drivers and teachers,'Bad or smoky smell on the air' and 'eye congestion' symptoms were increased during the events. The preventive behaviors were decreased or not changed in taxi drivers and bus drivers. In teachers,'close the window','diminishing the outdoor activities', 'diminishing the going out', 'wearing the sunglasses', 'washing the eyes after going out'. This results suggest that the outdoor worker's guideline during the Asian dust eventsneeds to be developed.

  • The purpose of this study was to survey primary students' perception of the global and local environmental issues. The subjects were 853 fifth primary students in Seoul, Busan, Daejeon, Anyang, Gimpo and Cheongju. The results were as follows: First, the perception level of the global environmental issues were global warming (M=3.99), drinking-water pollution (M=3.92), acid rain (M=3.77), yellow dust (M=3.66), ozone depletion (M=3.57), deforestation in tropical areas (M=3.52), desertification (M=3.36), biodiversity (M=3.40) and their perception level of local environmental issues were waste disposal (M=3.87), air pollution (M=3.74), bad smell (M=3.70), noise (M=3.61), river pollution (M=3.57), soil pollution (M=3.44). Second, it was shown that the metropolitan students' perception levels of environmental issues were higher than the non-metropolitan students'. There wasn't a significant difference in the perception levels of two scale environmental issues and characteristics for sex (p>.05). Third, the result of analyzing on the effects between characteristics was that the factors like 'environmental interest' and 'impact on personal life' had a strong influence on the 'behavior will' to solve the global environmental issues, and 'environmental interest' and 'personal knowledge' had a strong influence on the 'behavior will' to solve the local environmental issues. Fourth, the result of analyzing on the characteristics according to the types of the environmental issues showed that 'personal knowledge', 'environmental interest' and 'behavior will' were high in the global environmental issues (p<.01) and 'virtual contamination', 'human responsibility' and 'impact on personal life' were high in the local environmental issues (p<.05).

  • Soil purification theory is the method using the soil micro-organism like aerobic and anaerobic for treatment of wastewater. The soil has many kinds of micro-organism and it multiply as change of the environment. Unlikely other methods, the soil purification theory is adaptable to inflow water change; moreover, it can process the T-N, T-P without any special method and management. The top is covered with the improved soil which can remove the bad smell and is used for resting place according to planting the lawn. This study is focused on analysis of the treatment processing of wastewater comparing inflow with outflow water. As a results, removal rate of the processing the BOD, COD and SS is almost 90~100% and it is 60~80% in T-N, T-P.
