The pacific oyster Crassostrea gigas has a desirable taste and flavor that differs from those of other fish and shellfish. In order to develop a high value-added product from individually quick-frozen oyster extract (IQFOE), we prepared an oyster granular flavor seasoning (OGS) from IQFOE and characterized its qualities. The OGS was prepared by granular molding and fluidized bed drying with inosine monophosphate (IMP, 0.1%), yeast extract powder (1.4%), tangle extract powder (0.6%), monosodium glutamate (MSG, 5.0%), microcrystalline cellulose (0.6%), lactose (27.5%), salt (33.0%), spray-dried IQFOE (22.5%) as a powdered materials, and IQFOE ($Brix\;25^{\circ}$, 7.0%), soy sauce (0.4%) and water (1.7%) as a liquid materials. The moisture, crude protein, pH and salinity of the OGS were 3.4%, 12.5%, 6.50 and 32.0%, respectively. Especially, the OGS revealed very higher amino-N content (1,856.0 mg/100 g) than that (1,291.2-1,610.2 mg/100 g) of other commercial flavor seasonings. In taste-active compounds, free amino acid contents was 1,359.0 mg/100 g, and major ones were glutamic acid, taurine, hydroxyproline, glycine, lysine, phosphoserine, proline in order. And OGS showed good organoleptic qualities for taste, odor and general preference compared with commercial flavor seasonings on a local market.

The purpose of this study was to examine the dietary attitudes, dish preferences, and plate waste status of elementary school students in Chungnam province. Questionnaires fearuring dietary attitudes, dish preferences, and plate waste measurements over 4 days were administered to 278 elementary school students (3~6th grades; boys 124, girls 154). Regarding plate waste of food, subjects showed the following in decreasing order: soup > vegetable > fish > kimchi > rice > meat. Regarding food preference, cooked rice showed the highest preference among rice dishes, whereas both boys and girls preferred stir-fried rice among one-dish meals. For soup, soup cooked with mear was highly preferred. However, soup with vegetables was preferred less. For meat, soy sauce-glazed chicken and bulgogi were the most preferred boys and girls. In addition, boys indicated a higher preference for most of the meat dishes than girls. Among the many types of kimchi, Chinese cabbage kimchi (Baechu Kimchi) was the most preferred. For the school meals, the served and consumed amounts by boys were higher than those of girls. However, there was no significant difference in plate waste between the boys and girls. To improve management of school meals, dietitians should understand factors that influence students' food preferences.

Purpose: The purpose of the this study was to examine the dietary knowledge and educational needs of stroke patients and analyze the related factors that are associated with dietary knowledge and educational needs. Methods: Our study analyzed data from 146 stroke patients. The survey was conducted by individual interviews using questionnaires and data collected from participants' medical records. Dietary knowledge and educational needs were measured by tools developed by the author. Results: The mean scores for the dietary knowledge and educational needs were 19.09±3.48 and 36.17±7.18, respectively. Many stroke patients had misconceptions about soy sauce, cholesterol, and fruits. The most needed items in dietary education was first identifying foods that are beneficial or harmful, and second, food interaction with medications. As for the results of multiple regressions, dietary knowledge was significantly associated with gender, educational attainment, monthly income, exercise, body mass index, and level of compliance to dietary therapy. Additionally, the educational needs were significantly related with educational attainment and employment. Conclusion: For secondary prevention of stroke patients, education strategy considering dietary knowledge and educational needs of stroke patients should be established. Special attention is needed for stroke patients with a lower level of dietary knowledge and educational needs.

The purpose of the study was to assess students’preferences on vegetarian menus served at middle and high schools. Four school food service programs that served primarily vegetarian menus were located in Seoul, Kyunggi, Kangwon, and Choongnam provinces. A total of 100 menu items frequently served at the schools were identified. Students participating in the school meals programs were asked to assess their preferences of the menus using a 5-point Likert-type scale(1 : very dislike - 5 : very like). Excluding responses with significant missing data, usable responses were 659. Statistical analyses were performed with descriptive statistics, t-tests, and one-way analysis of variance. Menu items of the highest preference scores included kimchi stew, stir-fried kimchi, nangmyon(cold noodles), fried rice and kimchi, miso stew, soft tofu stew, and hard-boiled quail eggs in soy sauce. By menu category, one-dish foods(3.97) were the most preferred and muchim and namul were the least preferred. Female students showed higher preferences on kimchi, steamed items(jjim), stir-fried items, namul, and muchim than male students; middle school students’preference scores were higher than those of the high school students in most menu categories. The menu preference is known as one of the most important factors determining students’food consumption and satisfaction with school food service. Dietitians working at school food service programs that serve primarily vegetarian menus should provide students with nutrition education on proper food selection and focus their efforts on developing new recipes using various vegetables and preparation methods to improve students’food consumption and menu preference.

Background : Allergic rhinitis is the most frequently occuring immunological disorder. It affects men, women and children and represents significant cost in terms of suffering and loss of productivity. Objective & Methods : We referred to the information through Entrex Pubmed from 2004 to 2007 January about alternative medicine for allergic rhinitis, 9 treatises. Results : About 9 treatises, 2 treatises were for the acupuncture treatment, I treatise was for the acupuncture and chinese herbal medicine, 2 treatises were for the single substance(butterbur, soy sauce ingredients), 1 treatise was for the homeopathic preparation, 1 treatise was for the ayur-veda herbal treatment, 1 treatise was for the ultraviolet light phototherapy, 1 treatise was for the systematic review of alternative medicine. Except 2 treatises for the acupuncture treatment, 6 treatises used the double-blind, randomized, placebo-controlled methods. As a result, we found 5 treatises that treat group had more improvement than control group, 3 treatises that treat group had no difference control group on effect significantly. 1 review article exhibited the most of alternative medical literatures were inadequate methodologically and therapeutic efficacy alternative treatment for allergic rhinitis was not supported by currently available evidence. Conclusion : We found that treatises about the alternative medicine for allergic rhinitis were more and more published. We were supposed that many internal treatises were published adequately by methodology to prove Korean medical treatment effects for allergic rhinitis.

Korean Chochgal is a kind of salted, fermentive food mainly made of fish in our country. It has been a suitable side'dish for the diet of rice. It has made use of an accompaniment of wine, seasoning, food of ceremony and a folk remedy. There were various kinds of Chochgal and various way of for preparation. For a long time it has developed in how to cook and how to eat. Nowaday, it has lessened to use Chochgal. In this thesis, the kinds of Chochgal and the reference frequency to them, the material, the measuring unit of material, the making terms, and the cooking kitchen utensils are studied out of the 86 books published in Korea from 1200 to 1984. 1. It was classifed Choch, Sikhae, and Oyukchang as how to cook. 2. There were 147 kinds of Chochgal, 100 kinds of Choch, 40 kinds of Sikhae and 7 kinds of Oyukchang in our traditional documents. 3. Materials were classified into main material, sub-material, and seasonings. As main materials there were fish, internals of fish, spawn, flesh, salt and soy sauce. As sub-materials there were seasoning, flavor, vegetables and cereals. 4. There were 41 kinds of measuring units. Of them, 17 kinds are for volume, 9 kinds are for quantity, 3 kinds are for length, and 12 kinds are for the rest. 5. There were 52 kinds of cooking kitchen utensils. They used mainly a sieve and pebbles. To store Chochkal a kind of jar, a woodenware and a clay ware were used. To shelter it from the wind, they sealed it with leaves and oiled paper. But few of them are used nowaday. 6. There were 209 kinds of cooking terms. Of them, 35 kinds are for the washing process, 51 kinds are for the preparing process, 38 kinds are for the making process, 25 kinds are for the fermenting process, 24 kinds are for the keeping process, and 36 kinds are for the eating(using) process.

This study was conducted to screen for superior strains for preparation of Cheonggukjang and identify the optimal fermentation time based on fermentation of lentils by various Bacillus subtilis strains. Bacillus count was significantly high at 48 hrs of fermentation (9.22-9.51 log CFU/g). In addition, the pH was significantly high in the range of 7.60-7.92 at 48 hrs fermentation, and the reducing sugar content was significantly high (0.89-1.45). The amino-type nitrogen content and ammonia-type nitrogen content were significantly increased with fermentation time. Additionally, the amylase activity was significantly high (3.05-4.22) at 48 hrs of fermentation, as was the protease activity (4.80-5.63). Bacillus subtilis S3 (5.63), S4 (5.60) were higher than S1 (4.80), S2 (4.92). The viscous substances and DPPH radical scavenging activity increased at 48 hrs, then decreased. Sensory evaluation revealed that lentil Cheonggukjang fermented by S3 showed the highest scores in color, smell, savory taste, sweet taste, viscous substance and overall acceptability. Therefore, 48 hrs of fermentation should be suitable for lentil Cheonggukjang fermented by Bacillus subtilis S3.

This study was carried out to develop soybean thresher which is able to reduce the soybean threshing damage in comparison to the conventional thresher. A threshing cylinder with different diameter of 480 and 384 mm at each end and with one quarter disc pegs of 60 mm radius was developed and attached to the prototype thresher. A conventional thresher which has a threshing cylinder with $\wedge$ type threshing pegs and same diameter of 480 mm at each end was used for comparative test. A series of comparative performance test was conducted using sun-yu and chung-ja soybean. For sun-yu bean, which is white and usually used for soybean paste and soy sauce, the ratio of damaged beans of prototype ranged 2-3% for 330-360 rpm which is recommended cylinder speed by manufacturer. The ratio of damaged beans of conventional thresher was 3-4% for the same range of cylinder speed. chung-ja beans with black color usually shows high damaged ratio compared with white beans, thus cylinder speed of 250-300 rpm is recommended by manufacturer to reduce the damaged ratio. For this range of cylinder speed, the damaged ratio of prototype was 1.3-1.4% and it was 2.7-6.1% for the conventional thresher. Thus prototype is able to reduce the damaged ratio 1.5-5.0% compared with conventional thresher. Prototype shows 0.4% of unthreshed soybean ratio for sun-yu bean in the optimum range of cylinder speed and it was 0.87% for the conventional thresher. For chung-ja bean, the ratio of unthreshed soybean was almost same for both prototype and conventional thresher with the value of 4.0%. The reason of high unthreshed soybean ratio for chung-ja bean compared sun-yu bean is due to the high seed moisture content of 29.11% which is much higher than that of the recommended.
