  • This study was conducted to investigate the growth of soybean sprouts and the effective hormonal refutation of vitamin C content by the concentration and combination of kinetin and auxins such as IAA, 2.4-D and NAA. The results were as follows; 1. The growth of soybean sprouts were fine under the respective conditions of kinetin $10^{-8}M+IAA\;10^{-6}M$, kinetin $10^{-7}M+IAA\;10^{-5}M$, kinetin $10^{-6}M+IAA\;10^{-6}M$, kinetin $10^{-5}M+IAA\;10^{-7}M$, kinetin $10^{-8}M+2,4-D\;10^{-8}M$ and kinetin $10^{-7}M+NAA\;10^{-5}M$. 2. The root development of soybean sprouts were almost in accord with the growth of soybean sprouts by the concentration of kinetin and auxin. 3. The content of vitamin C were more increased under in kinetin $10^{-8}M+IAA\;10^{-8}M$, kinetin $10^{-6}M+2,4-D\;10^{-5}M$ and kinetin $10^{-8}M+NAA\;10^{-8}M$ and both growth and vitamin C content were more activated under kinetin $10^{-8}M+IAA\;10^{-6}M$ and $10^{-8}M+NAA\;10^{-8}M$. 4. The growth, root development and vitamin C content were increased in the low kinetin and high IAA, NAA concentration. Root development and vitamin C content of soybean hypocotyl were decreased in the low kinetin and high 2,4-D concentration.

  • This study was performed to examine the effects of Meju supplementation to high cholesterol diet on lipid metabolism in rats. Male Sprague-Dawley rats were divided into two groups(Steamed soybean, Meju) and were fed with 0.5% cholesterol diet. Serum and liver lipid profiles and fecal bile acids excretion were examined after four weeks of experimental diet. Food intake, weight gain and liver weight were not significantly different between the two groups. Total cholesterol concentrations in serum was significantly lower in Meju group compared to steamed soybean group(p<0.05). HDL-cholesterol, triglyceride, phospholipids and nonestrified fatty acid concentrations in serum were not significantly different between the two groups. Cholesterol, triglyceride, and phospholipids concentrations in liver were not significantly different between the two groups. Fecal bile acid excretion were markedly higher in Meju groups than the group fed steamed soybean(p<0.05). These results suggest that the cholesterol lowering effect by Meju supplementation might be resulted from the modulation of fecal bile acid excretion in rats.

  • Jangkimchi is a kind of Kimchi which is made with soy-sauce instead of salt. Occasionally, when sugar is added to Jangkimchi for condiment, the kimchi juice becomes viscous. In this study. the nature of the viscous material and the condition for producing viscous property in Kimchi juice were investigated. HPLC analysis showed that the viscous material in Jangkimchi is polysaccharide composed of glucose. Sucrose was more effective in forming viscous juice than glucose and the viscosity increased with the addition of sucrose up to 10%. Soy-sauce also played a role in increasing the viscosity of Kimchi juice compared with salt. Aerobic fermentation condition was found to be another factor to make the juice viscous. The population of Leuconostoc mesenteroides, well-known producer of viscous dextran was not different in the Kimchi juice prepared with the addition of sucrose from that without sucrose, which implys that the Jangkimchi preparation methods such as addition of sucrose and soy-sauce would do some effects on the production of viscous material in Jangkimchi.

  • This study is on the kindergarten uniforms in Changwon, south Gyeongsang province. The first part of this research is on whether or not students should wear uniforms and how often they should wear uniforms. The research also deals with what types of uniforms are required, how much they should cost and their size. Fifty one preschools including kindergarten and nursery were targeted for this research. The second part of the research is on the discrepancy of the labeled size and the actual size of the child. The results of the first part are as follows: A total of 46 out of 51 places adopted uniforms for their children. Sports wear style is the most popular for spring, fall and summer uniforms. For wearing frequency of kindergarten uniforms, 26 (61%) places allowed the students to wear uniforms for special events such as picnics or observation trips 17(34%) places had the students wear their uniforms on a daily basis and 2 3 times only wearing a week.'rho preschool children interviewed for this study were from 2 to 5 in lull age. However, sizes with high frequency rates were 9 to 11 and the supplied sizes of uniforms were from 5 to 17. The results of the second part are as follows: The bust girth and the shoulder width of upper garments of uniforms are bigger than children's physical size, while clothes length and sleeve length are relatively shorter. Also the bust girth of upper garments of uniforms differs in the size depending on each preschool. The waist girth and the total length of lower garments of uniforms are made smaller than children's physical sizes, while hip girth is relatively larger. In the case of lower garments, the rest parts of cloth length are smaller than upper garments of uniforms. Also, the waist girth and hip width of uniforms are smaller than those of lower garments In summer garments, while thigh width is similar in both cases. The waist width is made too small. Described in the above excluding the waist width, the rest parts are relatively larger than children's physical sizes, but shorter in the length. Due to the length, children at age 7 may wear uniforms in the level of 17. Since summer uniforms touch the students' bare skin, the rest parts excluding clothes length are shorter than these of the spring and fall uniforms. In the case of clothes length, it seems to be due to different designs. The waist width of lower garments in all the uniforms tested in this study is too small for children, requiring them to be made in a larger size.

  • With the increasing market share of retailer brands, many authors have paid considerable attention to retailer brands. Before market liberalisation in 1996 in Korea, retailer brand market was led by the supermarket retailing format, although the first retailer brand product was developed by the department store format. In parallel with the entry of foreign multiple retailers, the retailer brand market has experienced rapid growth. Particularly, the expansion of Tesco UK with well-established retailing know-how into Korea has encouraged Tesco Korea to actively get involved in retailer brand program. As a result, Tesco Korea has led retailer brand market in the Korean marketplace. The research starts with the question of why Tesco Korea has achieved such a higher retailer brand share. Accordingly, this study is to explore how Tesco UK has transferred its own retailing knowledge into Tesco Korea, in terms of retailer brand program development. In order to explore why the retailer brand share of Tesco Korea is higher than that of its counterparts, the author adopted in-depth interview with prepared-questions and store observation as a research methodology. To examine working process as well as information flows within Tesco Korea and from UK to Korea, in-depth interview method is one of the most suitable research methodologies, because of the difficulty of quantifying information or data related to work flows. In addition, to increase the validity of information, the researcher had interviews with Tesco Korea supplier and store personnel. Based on these research techniques, this research explored how Tesco UK has influenced or advised Tesco Korea, particularly, from the point of view of knowledge transfer. Since the entry of Tesco UK into Korea as a joint-venture, the retailer brand market share of Tesco Korea has continuously increased. It would be expected that Tesco UK has helped Tesco Korea to settle down in the Korean market. During interviews with Tesco and a Tesco supplier, the researcher found that Tesco Korea has obviously taken an advantage of retailing know-how created by Tesco UK. Furthermore, the retailer brand development and handling process of Tesco Korea has been operated with the help of Tesco UK. This might mean that Tesco UK has directly or indirectly an impact on the improvement of Korean retailer brand development skills. As a mechanism to transfer retailing knowledge developed in the home market into the host market, one of the international retailers, Tesco UK has adopted many different ways such as annual meeting, trading meeting to import or export own retailer brand products, offering of operation manual developed by Tesco UK and buyer cooperation between Tesco UK and Korea, in order to share information. Through these communication techniques, the knowledge of Tesco UK has been transferred to Tesco Korea. This research accordingly suggests that retailer brand market share is apparently related to how sophisticated or advanced the knowledge of the retailer brand development and handling process of retailers are. It is also demonstrated by this research that advanced development and handling skills make a considerable contribution to increasing retailer brand share in markets with a lower share or no presence of retailer brands.

  • Black rice bran powder has potential medical uses and functionality. In this study, we assessed the antioxidant activity and quality characteristics of cookies containing various concentrations (0, 1, 3, 5, 7, and 9%) of black rice bran powder. To analyze quality characteristics, proximate composition, fatty acid composition, amino acid composition, bulk density and pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations were measured. Black rice bran cookies (7%) contained more crude protein ($10.67{\pm}0.33$%) compared to control ($5.84{\pm}0.06$%). The total unsaturated fatty acid contents of the control and 7% black rice bran cookies were 30.44 and 30.81%, respectively. The amino acid content of 7% black rice bran cookie was higher than that of control. Bulk density of the dough, moisture, spread factor, total polyphenol content, and DPPH free radical scavenging activity of the cookies significantly increased with increasing content of black rice bran powder, whereas pH of the dough, loss rate, leavening rate, and L values of the cookies decreased. Additionally, consumer acceptability scores for the 7% black rice bran cookie group ranked significantly higher than those of the other groups in terms of appearance, taste, flavor, texture, and overall preference. Taken together, the results of this study suggest that black rice bran powder is an effective ingredient for increasing the consumer acceptability and functionality of cookies.

  • The purpose of this study was to analyze factors that influence consumption pattern of snacks of middle school students. The subjects of study were 607 middle school students (male: 316, female: 291) in Ilsan area. The subjects were surveyed by a self-administered questionnaire about anthropometrics, mother's employed status, parents' education level, and snack consumption pattern. Male students showed higher consumption in 'milk and milk products' (p<0.05), 'instant noodles' (p<0.01), and 'cereal' (p<0.05). In the other hand, female students showed higher consumption in 'biscuits, cookies' (p<0.01) and 'candy and chocolates' (p<0.01). Subjects in underweight group showed higher frequency in the consumption of 'biscuits, cookies' (p<0.05) and 'candy and chocolates' (p<0.001) compared with normal weight or overweight subjects. The subjects with mother not having a job showed higher consumption of snacks under controlling parents (p<0.001), and higher consumption in 'fruit and fruit juice' (p<0.05) and 'milk and milk products' (p<0.01) compared to the subjects with mother having a job. The subjects with parents having higher education level showed higher of consumption in 'fast food'. These results suggest that general characteristics of the subjects and characteristics of family environment may affect consumption pattern of snacks in middle school students.

  • In this treatise, we investigated the Korean literature of main dishes before the 17th century : ${\ulcorner}Sangayorock{\lrcorner}$, ${\ulcorner}Sasichanyocho{\lrcorner}$, ${\ulcorner}Soowonjabbang{\lrcorner}$, ${\ulcorner}Yongjechongwha{\lrcorner}$, ${\ulcorner}Dongyoebogam{\lrcorner}$, ${\ulcorner}Domoondaejak{\lrcorner}$, ${\ulcorner}Geebongyouseul{\lrcorner}$, ${\ulcorner}New-Guwhangchalyo{\lrcorner}$, ${\ulcorner}Eumshickdimibang{\lrcorner}$,, ${\ulcorner}joobangmoon{\lrcorner}$, and ${\ulcorner}Yorock{\lrcorner}$. Main dishes were classified 19 kinds of rice, 64 kinds of gruel, 6 kinds of thin gruel, 1 kind of Moori, 1 kind of rice-cake soup, 37 kinds of noodles and 20 kinds of dumpling. Rice varieties were brown rice, rice, hulled rice, millet rice, foxtail millet rice, barley rice, sesame rice and flax seed rice. Gruel ingredients were cereal, beans, vegetables, nuts or seeds, medical plants or hardy wild plants, poultry, pork's kidney, dog's liver or oyster, clam and/or milk Rice-cake soup was 'Tangbyun' in ${\ulcorner}Domoondaejak{\lrcorner}$. Noodles were divided by main flours: wheat flour, buckwheat flour, mung bean flour and other flours. Noodles were made by pressing or cutting method. Pressing method used a mold with a hole. The husk of dumpling was made by wheat flour, buckwheat flour, mixed flour of wheat and buckwheat, sliced fish or meat, and/or a gray mullet. Another special method was 'Sangwha' made by fermentation. Bun stuffing of dumpling used fishes, meat, vegetables, beans, flours and seasonings. Cooking methods of dumpling were boiling, baking, steaming and pan-frying. From this investigation of the Korean main dishes described in the Korean literature before the 17th century, we expect to develop useful recipes for those who are concerned about health and want longevity, and thereby to advance the Korean food culture.

  • A strain of yeast (Candida guilliermondii KFCC 35120) was cultivated by using the soybean whey with supplement of blackstrap molasses (4%) and ammonium acetate (0.5%). By the cultivation continued for 48 hours, 8.1g of dry cell was produced. The cell was consisted of carbohydrate 39.3%, protein 40.5%, lipid 3.9%, nucleic acid 9% and ashes 6%. The protein was analyzed to contain 18% of glutamic acid and 10% of lysine. Other amino acids showed a content near that of FAO reference protein except Methionine. Total lipid content was varied by nutritional condition especially by the kind of carbon source, however it showed a content 1.7 to 2.5 times higher than that of Saccaromyccs cerevisiae. The lipid contain 48% of oleic acid, 17% linoleic acid and 4% linolenic acid. The content of linoleic and lonolenic acid was higher than that of S.cerevisiae by 9 and 24 times, respectively.
