        The compulsory beef labelling system has launched from January 1st 2007 by the amended Food Hygiene Law, we were checked the actual conditions of beef origin with a nationwide scale by the Hanwoo differentiation specific test method which was developed by Korea FDA using 90 SNP biomarkers. The test method is useful tool to differentiate the beef origin carrying out the mission of KFDA's annual food safety management guidance. Also we have technically transferred the Hanwoo differentiation specific test method to other institutes as well regional KFDA and established the training program as a regular course in Korea Human Resource Development Institute for Health and Welfare. The beef used in this study were collected according to the 2009 Food safety guidance in roast beef restaurants where business site area greater than 100 m2. Total 216 samples were consisted of 48samples of the Seoul area and 168 of the region. The monitoring result from restaurants in all the region of Korea showed that 3 of 216 Hanwoo-labelled beefs were found out as a non-Hanwoo (1.3%). This results are gradually deceasing trend compared with 34.0% in 2005, 30.1% in 2006, 3.2% in 2007 and 5.14% in 2008. From these data, the Hanwoo differentiation specific test method on the settlement of the compulsory beef labelling system has an important role. As a outcome of this project, we might be considered the early settlement of the compulsory beef labelling system, technically transferred to other institutes and the establishment of regular training program of the test method.

        한국어교육 현장에서 연어를 이용한 어휘교육은 한국어 학습자가 자연스러운 한국어를 구사할 수 있도록 정확성과 유창성을 높여줄 수 있다. 그러나 연어는 어휘 간 결합관계의 예측 불가능성과 비대칭성으로 인해 상세한 분석과 기술이 요구되며 반드시 외국인 학습자들에게 효과적으로 제시되어야 한다. 그리하여 학습자가 단순히 연어를 암기식으로 학습하는 것이 아니라 그어휘가 성립되는 관계를 이해하여 한국어의 유창성을 향상시키는데 도모해야 할 것이다. 본고에서는 한국어 학습자의 효율적인 연어 학습을 위해 어휘 사이의 의미관계, 특히 연어 관계의 체계적인 기술을 가능하게 하는 장치인 멜축(Mel'čuk)의 어휘함수를 활용하여 연어의 구성요소들이 맺는 어휘적 의미 관계를 중심으로 기술하는데 기초적 자료가 되는 것에 의의를 두고자 한다.

        Bamboo leaf powder was added to Chiffon cake to increase its neutraceutical effects and storage periods. Specifically, 0, 7, 10 and 13% leaf powder was added to the cakes. The content of total dietary fiber in the bamboo leaf powder was 65.57%. The moisture content did not differ significantly among groups. The cake containing 10% bamboo leaf powder had the greatest volume, whereas the control group (0% bamboo leaf powder) had the lowest volume (p〈0.05). The Hunter's L and a values decreased significantly as the amount of bamboo leaf powder increased. The b value of the control was lowest among the groups (p〈0.05). Evaluation of the consumer acceptance of flavor revealed that the cakes containing the added bamboo leaf had greater consumer acceptance than the control. However, when the color was evaluated, the 13% group showed the lowest acceptance (p〈0.05). Other factors such as texture, taste and overall acceptance did not differ significantly among groups. Additionally, the elasticity did not differ among groups, while the air cells were most uniform in the control. The strength of bamboo leaf aroma, bitter taste and aftertaste increased as the amount of bamboo leaf powder added increased. Cakes containing 10% and 13% added powder had the greatest moisture content, while the control had the lowest content (p〈0.05). As in previous studies, the results of this study indicated that 10% bamboo leaf powder was the optimal level for the preparation of Chiffon cake. To evaluate the storage of cakes, the 10% group and the control were inoculated with Aspergillus oryzae and then incubated at 30℃ for 6 days. The microbial colony counts in the control group were dramatically increased after 48 hrs; however, the fungal concentration of the 10% group did not increase for 4 days. In conclusion, the addition of 10% bamboo leaf powder to Chiffon cake increased the storage time while maintaining adequate consumer acceptance.

        현재 방송 영화 기록물은 수집 관리 체계가 미흡하여 망실의 위험이 상존하고 있다. 또한 수집 관리 기관의 이해관계에 따라 국가 기록물의 접근이 폐쇄적이다. 따라서 영구보존 가치를 지닌 방송프로그램 영화 기록정보 수집관리를 체계화하여, 국가의 역사 문화 기록유산으로 보존 및 활용을 위한 중장기 계획을 수립하여 추진하여야 할 것이다. 본 연구는 선진 국가의 방송 영화 기록물 체계를 비교 분석하여 우리나라 기록물 수집 관리 제도의 문제점을 도출하고 개선 방안을 제시하고자 한다. 연구결과, 방송프로그램의 경우 프랑스와 미국 등은 방송프로그램에 대한 법적 의무납본 및 자발적 납본을 채택하고 전문적인 공공방송영상아카이브를 운영, 안정적으로 수집 관리하고 있다. 영화의 경우엔, 거의 모든 선진 외국이 의무 납본제를 통해 체계적으로 관리하고 있다. 이에 우리나라에서도 총괄 관리 기능을 수행할 독립적인 성격의 국립 방송 영화 아카이브 설립될 필요가 있으며 안정적인 방송영화 기록물의 수집을 위해 의무 납본제를 실시하여 국가기록물의 멸실을 방지해야 할 것이다. 이를 위해서는 법, 제도의 개정이 필수적으로 이루어져야 할 것이다.

        The principal objective of the present study was to survey the demands of an education program for evaluations of the efficacy of health functional foods. A questionnaire was developed and sent to 2,225 members of the Biofood Network Center. A total of 101 (4.6%) individuals responded, 54.5% of the respondents were male and 45.5% were female; the respondents' occupations (in order of prevalence) were as follows: company worker (48.5%)〉researcher (27.7%)〉student (13.9%)〉professor (5.0%)〉pharmacist (2%), and dietitian (2%). The businesses in which the respondents worked were (again in order of prevalence) as follows: research & development (64.4%)〉marketing (11.9%)〉consultation and education (5.9%)〉manufacturing and others (17.9%). 41.6% of the respondents reported experience in businesses relevant to KFDA approval for functional ingredients and health functional foods. The results showed that 63.4% of the respondents had previously been educated about functional foods; the types of education program reported were (in order of prevalence): 'overview and acts of health functional food' (n=49)〉'standards and specification for health functional food' (n=41)〉'efficacy evaluation-human study' (n=24)〉'safety evaluation' (n=21)〉'efficacy evaluation-in vivo study' (n=13)〉and 'others' (n=10). Respondents preferred off-line education programs (62.4%) to on-line programs (22.8%). The preferred duration of an educational program was '2~3 days: total 14~24 hours' (30.7%); thus, short-term programs were favored. The primary requirements of a program, from the perspective of the learner, were as follows (scored on a 7-point scale); 'efficacy evaluation and case study-human study' (5.80 points)〉'standards and specification for health functional food' (5.72 points)〉safety evaluation' (5.7 points)〉'overview and acts of health functional food' (5.67 points) and 'efficacy evaluation methods of health functional food by efficacy (intensive)' (5.67 points). Preference for functionality was as follows; 'body weight & body fat' (21.8%), 'immune function' (18.8%) 〉 'blood glucose' (10.9%). In summary, the educational demand for 'efficacy evaluation and case study' was highest among the curriculum options provided, and with regard to functionality, 'body weight & body fat', 'immune function' and 'skin care' were considered most important by respondents. These results differed among respondents with different jobs and duties, and this suggests that customized education programs for health functional food should be developed.

        The objective of this study was to assess the quality characteristics of morning-rolls containing various levels (0, 4, 8, and 12%) of bamboo leaf powder. The results demonstrated that morning-roll volume decreased with increasing amounts of bamboo leaf powder, and as the bamboo leaf powder content increased, the Hunter's color 'L', 'a' and 'b' values were significantly reduced (p<0.05). For the amylogram characteristics, the addition of bamboo leaf powder to the flour reduced peak viscosity, holding strength, final viscosity, and setback. The results of the sensory evaluation demonstrated that control (0%) and 8% addition of bamboo leaf powder had the best scores in taste, color, flavor, texture, appearance, softness, wetness, residual mouth feel, and overall acceptability. Thus, it appears that by using 8% additions of bamboo leaf powder, the functionality, nutritional composition, taste, color, and flavor of morning-rolls containing bamboo leaf powder can be developed. This result will support the development of better quality bamboo-leaf morning-rolls.

        The principal objective of this study was to determine the effects of diet knowledge and perception on diet practice behavior among university students. Data were collected between March and April of 2005 from 523 male and female university students in Seoul and Chungbuk, via a self-administered questionnaire. The subjects included 217 male students (41.5%) and 306 female students (58.5%), and 52.0% of the subjects were 21-23 years old. With regard to residence type, 42.6% of the subjects lived in the dormitory, home (29.1%) self-boarding (19.5%) and meal (8.8) were in the order. The average weights and heights of the subjects were as follows: 70.9±9.0 kg and 174.3±4.4 cm in the male students and 53.9±5.9 kg and 161.3±4.5 cm in the female students. The average BMI values of the male and female students were 23.4±2.5 and 20.8±2.1, respectively. The average nutritional knowledge scores were as follows: 1.96 out of 3.0, dietary habit (2.13), nutrition (2.0), exercise (1.98), preferred food (1.90), and chronic disease (1.79). We noted no significant differences between the male and female subjects in terms of scored points. Nutritional knowledge by gender and residence type were shown to be significantly different--the male subjects had higher scores for exercise than did the female subjects. The self-boarding subjects had significantly lower scores with regard to nutritional knowledge and chronic disease. The experience and duration of previous diet practice were also significantly different with regard to gender and residence type. The male subjects tended to conduct diet practice for longer periods than females. The self-boarding students reported more attempts at diet behavior, but for shorter durations. The results show that the nutritional knowledge and diet practice behavior of the subjects were influenced by gender and residence type.

        The breast feeding habits of 507 college students were evaluated between March 27 to April 26 (2006). Data were collected from self-administered questionnaires and analyzed using SPSS for Windows V.12.0. The study population consisted of 245 (48.3%) male and 262 (51.7%) female college students that answered ‘yes’ when asked whether they had been breast feed. A total of 52.7% of the study population were fed with breast milk (most frequent answer), as opposed to 11.0% that were fed with infant formula (least frequent answer) during their infancy. When asked whether they ever got educated on breast feeding, 78.1% of the college student subjects answered ‘no’. A total of 95.1% of the female college students replied ‘yes’ when asked if they intended to breast feed their child. Moreover, 62.2% of the college student subjects indicated that their parents had an influence on their decision to breast feed. A comparison between male and female college students indicated that female college students had a superior knowledge level of the general characteristics of breast feeding over the male subjects (p<0.05) . Moreover, a comparison of the different levels of college attained suggest that freshman college students had the highest knowledge level, followed by senior, sophomore and junior college students in terms of advantage, BF Tabu (p<0.05). Also, students provided with education on breast feeding had a higher knowledge level than college students with no formal education. In summary, the results suggest that the knowledge on breast feeding in college students were different by general characteristics such as gender, major and school year, and education on breast feeding in advance was appeared to be an important factor, therefore nutritional education course on breast feeding is recommended for the college students.

        This study was designed to evaluate the effects of fructose(F) or sucrose(S) and guar gum intake on carbohydrate and lipid metabolism in 15-week-old male Goto-Kakizaki(GK) rats. Fifty rats were randomly assigned to 5 groups which were different in carbohydrate(25% of carbohydrate) and fiber(5% w/w) sources. The carbohydrate(CHO) sources of each group were comstarch(control group, 100% of CHO), fructose with cellulose(F), fructose with guar gum(FG), sucrose with cellulose(S), and sucrose with guar gum(SG). Each group was fed exterimental diet for 4 weeks. We measured food intake, body weight gain, adipose tissues weight and organs weight. We conducted oral glucose tolerance test(OGTT) and measured plasma insulin concentration to examine carbohydrate metabolism. To evaluate lipid metabolism, we measured the lipid profile of plasma, liver and feces. Food intake and weight gain of FG or SG groups tended to be less than those of F or S groups. Perirenal and epididymal fat pad weights of SG group were significantly lower than those of S group and those of FG group tended to be lower than those of F group. In OGTT, blood glucose values of F or S groups were significantly higher than those of C group, and FG or SG groups tended to be lower than those of F or S groups during the experimental time. The area under the curve(AUC) of C group was significantly highest among the groups, AUC and plasma insulin concentration of FG or SG groups tended to be lower than those of F or S groups. Plasma and hepatic triglyceride (TG) of FG and SG groups were significantly lower than those of F and S groups, plasma and hepatic total lipid(TL) and total cholesterol(TC) of FG and SG groups tended to be lower than those of F and S groups. Fecal TL, TG and TC of FG or SG groups tended to be higher than those of F and S groups. In conclusion, intake of guar gum should improve carbohydrate and lipid metabolism in partial substitution of fructose or sucrose for cornstarch in GK rats.

        Recently, epidemiological evidence has raised concerns that moderate elevation in body iron stores may increase oxidative stress and the risk of cardiovascular disease and cancer. Onion flesh or peel contains antioxidant such as flavonoids and alk(en)ylcysteine sulphoxides. This study was conducted to examine the effect of onion flesh or peel feeding on antioxidative capacity in aged rats supplemented with high dietary iron. Thirty-two Sprague-Dawley male 16-month-old rats weighing 618±6g were acclimated for 10 days with medium-iron diet (35ppm in diet), and blocked into 4 groups according to their body weights and raised for 3 months on either control diets (adequate iron-35ppm or high iron-350ppm) or experimental diets containing onion flesh/peel (5% w/w in diet) with high iron (350ppm). Rats fed high iron-onion peel diet had significantly high quercetin and isorhamnetin levels in plasma whereas rats fed high iron-onion flesh diet did not show. Plasma TBARS level was lowered by onion flesh or peel diet with high iron supplementation. However, there was no significant difference in cellular DNA damage in brain and kidney tissue among all experimental groups. We concluded that high iron diet (10 times higher than requirement) tend to increase oxidative stress and it is plausible that onion flesh or peel feeding enhances antioxidative capacity in the elderly even with iron supplementation.

        This study was peformed to investigate effect of feeding experimental mixture containing chitosan, hibiscus extract and L-carnitine on body weight and lipid metabolism in rats. Forty-eight male rats(Charles River CD) of eight weeks old and weighing 336.5±2.3g were raised for five weeks with high fat diet(40% fat as calorie) to induce obesity. After induction of obesity, rats weighing 560.4±5.6g were blocked into four groups according to body weight and raised for eight weeks with diet containing either 0.09%(+1D group), 0.9%(+10D group) or 4.5%(+50D group) of experimental mixture. Aspartate aminotransferase(AST) and alanine aminotransferase(ALT), total protein and albumin were normal levels in plasma. Body weight gain and epididymal fat pad weight were lower in experimental mixture groups than control group However, weights of perirenal fat pad and brown adipose tissue were not significantly different among all groups. There was no significant difference in plasma and hepatic lipid levels among all groups. Liver citrate lyase and camitine acyltransferase activities were not significantly different among all groups, however, citrate lyase activity was tended to be decreased with increasing experimental mixture level in diet. Fecal total lipid and total cholesterol excretions were highest in +50D group, and triglyceride excretion was highest in +1D group. in conclusion, intake of experimental mixture containing chitosan, hibiscus extract and L-camitine was effective in reducing body weight and body fat, and its inhibitory effects might lead to obesity improvement.
