This study was carried out to analysis the factor effected by milling rice rate, and to provide the developing rice varieties and cultivation technology. Panicle numbers per spike of Ilpumbyeo and Chucheongbyeo were 105 and 70, respectively. The primary branch panicle rate was Ilpumbyeo 56.2% and Chucheongbyeo 61.4%. The secondary panicle rate of Ilpumbyeo and Chucheongbyeo was 43.3% and 37.9%, respectively. Grain filling rate using specific gravity showed that Ilpumbyeo was the lower filling rate than Chucheongbyeo. Hull weight per one grain was Ilpumbyeo 41.9 mg and Chucheongbyeo 3.92 mg, and hull weight per rough rice 1 kg was Ilpumbyeo 157.36 g and Chucheongbyeo 151.31 g. In milling rate, brown rice ratio by ripening degree of llpumbyeo and Chucheongbyeo with combine harvest was 81.22% and 82.52%. Milled/brown rice ration of llpumbyeo and Chucheongbyeo showed 92.14% and 92.51%. The milling recovery ratio of llpumbyeo was decreased 1.67% then Chucheongbyeo, and the difference was mainly due to the hull weight (0.61%), milled/brown rice ratio (0.37%) and ripening degree (0.69%). Although the varietal differences were found in hull weight and millied/brown rice ratio between llpumbyeo and Chucheongbyeo, the ripening degree was considered as the factor that could be reduced by cultivation technology and post-harvest management.

The effects of administration alone or mixed of Angelica keiskei and turmeric extract on blood lipids were evaluated in hypercholesterolemic diet or P-407-induced hyperlipidemic rats. In the study 1, female Sprague-Dawley rats weighing 160-180 g were divided into each groups and fed high cholesterol diets for 8 weeks. Experimental groups were administered with following diets: basal diet (Normal), high cholesterol diets (1% cholesterol). We did the oral administration for evaluation in experimental groups: C (vehicle), A (angelica extract), T (turmeric extract), AT (angelica extract, turmeric extract/ 1:1 complex). The concentrations of serum total cholesterol, and LDL-cholesterol were decreased by 6.8%, 9.8% in A group, by 22.1%, 28.8% in C group and by 28.2%, 35.6% in AT group, compared to the C group, respectively. HDL-cholesterol levels were not different among the experimental groups. In the study 2, we induced the hypertriglyceridemia in rats by intraperitoneal injection of P-407 (0.5 g/kg) once per three days. From the next day after P-407 injection beginning, we did the oral administration as the study 1. Angelica keiskei extract, turmeric extract and complex extract decreased serum triglyceride by 17.2%, 19.7% and 48.3%, respectively. These results suggested that Angelica keiskei and turmeric extract complex might have synergistic effect in lowering total cholesterol, LDL-cholesterol and triglyceride in hyperlipidemic rats.

The results of the study of diving the 21st century's Korea fashion market into consumer market, fashion market, and a new marketing strategy are as follows. The 21st consumer market is First, a fashion democracy phenomenon. As many people try to leave unconditional fashion following, consumer show a phenomenon to choose and create their own fashion by subjective judgements. Second, a phenomenon of total fashion pursuit. Consumer in the future are likely to put their goals not in differentiating small item products, but considering various fashion elements based on their individuality and sense of value. Third, world quality-oriented. With the improvement of life level, it accomplishes to emphasize consumers' fashion mind on the world wide popular use of materials, quality, design and brand image. Fourth, with the entrance of neo-rationalism, consumers show increasing trends to emphasize wisdom, solidity in goods strategy pursuing high quality fashion and to demand resonable prices. Fifth, concept-oriented. Consumers are changing into pursuing concept appropriate to individual life scene. Prospecting the composition of the 21st century's fashion market, First, sportive casual zone will draw attention more than any other zone. This is because interest in sports will grow according to the increase of leisure time and the expasion of time and space in the 21st century, and also ecology will become the important issue of sports sense because of human beings's natural habit toward nature. Second, the down aging phenomenon will accelerate its speed as a big trend. Third, a retro phenomenon, a concept contrary to digital and high-tech, will become another big trend for its remake, antique, and classic concept in fashion market with ecology trend. New marketing strategy to cope with changing fashion market is as follows. First, with the trend of borderless concept, borders between apparels are becoming vague, for example, they offer custom-made products to consumers. Second, as more enterprises take the way of gorilla and guerrilla where guerrillas who aim at niche market show up will develop. Basically, they think highly of individual creative study, and pursue the scene adherence with high sensitiveness. However this polarization becomes mutually-supplementing relationship showing gorilla's guerilla movement, and guerilla's gorilla high-tech. Third with the development of value retailing, enterprises pursuing mass merchandising of groups called category killers are expanded and amplified to new product fields, and expand business' share. Fourth, using outsourcing, the trend to use exterior function leaving each enterprise's strength by inspecting its own work is gradually strong. Fifth, with the expansion of none store sale, the entrance of the internet and the CD-ROM sales added to communication sales such as catalogues are specified. An eminent American think tank expect that 5-5% of the total sale of clothes and home goods in 2010 will be done by none store sale. Accordingly, to overcome the problems, First international, global level marketing, Second, the improvement of technology, Third, knowledge-creating marketing are needed.

Study the effect of stress factors and increases in stress at work on the changes in eating behavior and habits and the influence of these changes on the health of dental hygienists. Use the responses of 273 dental hygienists who work in or around the Seoul area after surveying them by post or face to face. The biggest reason for skipping breakfast was having no time (60.4%) and the most desired change in eating habits was over eating (33.0%) while 51.6% responded that they over ate or binge ate due to stress. The largest stress factor was work load 39.6% and subjects responded that after stress the amount of food consumed increased very much for 12.1%, very for 49.8%, indicating increased food consumption than usual. The group with the most job stress had a high level of self stress awareness (p<0.001), nervousness (p<0.01), back pains (p<0.001), optical fatigue (p<0.01), headache (p<0.01) and indigestion (p<0.01). The higher the job stress, the poorer the eating behavior was (p<0.01) and job stress was high for dental hygienists working in dental clinics with less than three dental hygienists (p<0.05). Low eating behavior scores could be seen in groups that took 4 night shifts per week (p<0.05). Job stress scores for high for groups with no break time during work (p<0.001) and these groups showed low eating behavior scores (p<0.01). Furthermore, if high levels of self stress awareness was present, job stress was very high (p<0.001) and eating behavior scores were the lowest (p<0.05). Job stress of dental hygienists impede the eating behavior and habits therefore has a negative influence on their health. There is a need for more efforts to solve this problem and thus maintain the health of dental hygienists.

The purpose of this study was to help improve oral health care planning for the elderly in an effort to promote the oral health of elderly people in preparation for aging society. The subjects in this study were 200 elderly people who were selected by random sampling from senior centers in Seoul. An interview was conducted to gather data from June to September 2008, and the data collected were analyzed.: 1. The mean number of residual tooth was 13.71. 2. Concerning connections between gender and subjective oral symptoms, gender had a statistically significant relationship to temporomandibular joint dysfunction(p=0.000), dry mouth(p=0.001) and halitosis(p=0.006). The men underwent more oral symptoms than the women. 3. As for the relationship of mastication(p=0.000), oral pain(p=0.010), temporomandibular joint dysfunction(p=0.010) and dry mouth(p=0.001) to subjective oral health state, the elderly people who were not in a good oral health suffered more oral symptoms, and the gap between them and the others was statistically significant. 4. A larger number of tooth led to less mastication difficulties, less dry mouth and more gingival diseases, and the relationship between the factors was statistically significant. A better oral health state led to less mastication difficulties, less oral pain, less dry mouth and less bad breath, and the relationship between the factors was statistically significant. Through this study the oral health the elderly people perceive wss concerned with oral symptom, and the number of residual teeth also had links to subjective oral symptoms. Therefore, to maintain original teeth of the elderly people, the management system of oral health and the education program for oral health in order to prevent disease relateded with oral and enhance the perception standard of oral state are indispensably necessary to the elderly people.

This study was implemented to evaluate food safety on residual pesticides in agricultural products of Korea and to use as a data base for the establishment of food policy. A total of 196 pesticide upon these products were analyzed using multi class pesticide multiresidue methods of Korean Food Code, and 232 samples of 15 agricultural products collected from 9 regions were supplied for this study. In the results, 64 kinds of pesticides were detected in 53 samples, chlorpyrifos and procymidone of them were shown a high frequency of detection in the analyzed pesticides. Among them, two samples (chlorpyrifos in perilla leaves and picoxystrobin in peach) were detected over Maximum Residue Limits (MRLs). The levels of the detected pesticide residues were within safe levels. Also, the intake assessment for pesticide residues including chlorpyrifos at multi pesticide residue monitoring were carried out. The result showed that the ratio of EDI (estimated daily intake) to ADI (acceptable daily intake) was 0.001~0.902% which means that the detected pesticide residues were in a safe range so that residual pesticides in the agricultural products in Korea are properly controlled.
