  • This study compares salt-related dietary patterns according to sodium intake. A survey was conducted with 257 college students(130 male and 127 female students) in the Busan area. Dish Frequency Questionnaire 70(DFQ 70) was used to quantitatively estimate sodium intake. A short dish frequency questionnaire(DFQ 15) was used to screen subjects with high or low- salt intake. The sodium intake of male students based on DFQ 70 was significantly higher than that of female students(p<0.05). Sodium intake has significant negative effects on systolic and diastolic blood pressure(p<0.05). In the high-salt intake(HS) group, classified by DFQ 15, the number of male students was significantly higher than that of female students(p<0.01). The systolic blood pressure of the HS group was significantly higher than that of the low-salt intake(LS) group(p<0.05). Salt-related dietary behavior score and eating habit score for the HS group were significantly higher than those for the LS group(p<0.01). The sodium intake of the HS group based on DFQ 70 was significantly higher than that of the LS group(p<0.01). In these results, college students in Busan area showed high blood pressure and high sodium intake compared to Korean DRIs. The results indicate a need for various education programs to help college students practice a low-sodium diet.

  • This study was conducted to select and screen for an antifungal bacterial strain showing pathogen inhibitory activity against Diaporthe actinidiae, which causes stem-end rot in kiwi fruit. Four bacterial strains were isolated which strongly inhibit Diaporthe actinidiae from among two hundred and fifty bacterial strains screened from the soil where kiwi fruit were grown. By co-culturing bacterial strain #72 and the pathogen causing the stem-end rot of kiwi fruit, bacterial strain #72 showed 81.0% antifungal activity against Diaporthe actinidiae. Bacterial strain #72 was identified to be from the genus Bacillus sp. based on morphological and biochemical characterization. The bacterialization of culture broth for Bacillus sp. #72 which was sterilized at $121^{\circ}C$ for 15 minutes and than purified by $0.45{\mu}m$ membrane filter showed almost all of the antagonistic activity against Diaporthe actinidiae. We have also confirmed that in vitro treatment of Bacillus sp. #72 cultured in SD+B+P(sugar 5%, soy sauce 3%, beef extract 0.2%, peptone 0.2%) medium efficiently inhibited the growth of Diaporthe actinidiae responsible for stem-end rot in kiwi fruit.

  • This study investigated relationships between the importance and satisfaction of rice-based menu selection attributes at family restaurants. For data collection, a total of 250 copies of questionnaires were distributed to 4-year college students who had an experience of a rice-based menu at casual dining restaurants, and finally 221 surveys (88.4%) among them were analyzed by using SPSS Win ver. 11.5. Twenty selection attributes were used to test the level of importance and satisfaction for rice-based menu. The factor analysis identified six dimensions of the importance of rice-based menu selection attributes; variety of items, menu information, recommendation & atmosphere, food quality, preferred menu, and price. Also, five dimensions of satisfaction were identified as nutrition & taste, menu information, preferred menu & atmosphere, variety of items, and cooking. Canonical correlation analysis revealed that preferred menu factor of importance was highly correlated with preferred menu and restaurant atmosphere factor of satisfaction of rice-based menu selection. The managerial implications of these results for rice-base menu selection attributes are as follows: There seems to be a need to develop a variety of rice-based menus, because rice-based menus tend to be considered as an additional menu, not a main course. Aggressive marketing and communication strategies are necessary to position rice-based menu as a main course for college students and as a major maket segment to family restaurants.

  • 암을 제외한 대부분의 성인병은 혈액순환과 관련된 혈관계 질환들로 이들에 의한 사망 비율의 합은 암의 비율과 비슷하게 나타나 혈관계 질환의 심각성을 나타내고 있다. 혈전에 의한 혈관계 질환은 혈전용해제와 트롬빈저해제를 이용하여 치료하고 예방할 수 있으며, a-glucosidase 저해제는 당뇨병 예방과 치료에 이용할 수 있다. 예로부터 민간요법에서 다양하게 이용되어 왔던 반하를 성인병 치료와 예방에 관련된 기능성식품의 자료로 사용하기 위해 반하 열수추출물을 유기 용매로 분획화하고 분획물의 혈전용해활성, 트롬빈저해활성, 혈당강하효과를 측정하였다. 혈전을 직접 용해하는 활성을 측정하기위해 100 mg/ml의 농도로 준비한 시료액을 fibrin plate 방법을 이용하여 혈전용해활성을 측정 결과 hexane 층, chloroform 층, ethyl acetate 층, butanol 층에서는 활성을 나타내지 않았지만 물 층에서 만 0.8 plasmin unit의 높은 혈전용해활성을 나타냈다. 혈전의 형성을 억제하기위해 혈전형성의 필수 효소인 트롬빈의 활성을 저해하는 트롬빈저해활성을 측정하기위해 10 배 희석한 (10 mg/ml) 시료 용액을 이용하여 트롬빈저해활성을 측정결과 hexane 층에서 75.3%의 높은 트롬빈저해활성을 나타냈으며, ethyl acetate 층과 chloroform에서도 각각 43.3%와 39.7%의 활성을 나타냈다. 또한 탄수화물의 소화를 지연시킴으로서 소장에서 포도당의 흡수를 억제하여 혈관내 당의 농도를 조절하는 혈당강하제의 개발을 위해 준비된 조효소액(10 mg/ml)을 이용하여 a-glucosidase 저해활성을 측정한 결과 ethyl acetate 층과 hexane 층에서 각각 24.9%와 23.4%의 저해활성을 확인하였다. 따라서 반하의 hexane 층과 ethyl acetate 층과 물층은 혈전관련 혈관계 질환과 당뇨병 관련 기능성 식품의 개발 소재로 이용할 수 있을 것으로 기대된다. 특히 최근 질병 치료에 효과는 크지만 부작용이 동반되는 화학약품들 대신 활성은 조금 뒤지지만 부작용이 없는 생약을 이용하려는 경향이 커지고 있다. 따라서 오랫동안 민간용법에서 사용되고 있는 반하는 안정성이 확인된 장점을 갖고 있어, 식품재료나 기능성 음료에 이용할 경우 장기간 섭취가 가능해 혈관계 질환의 치료와 예방에 큰 효과를 가져 올 수 있을 것으로 기대된다.

  • Non-timber forest products are important component of subsistence and livelihood of tribal communities living in and near forests. This is of particular significance in the state of Arunachal Pradesh having more than 80% of geographical area under forest cover and predominantly inhabited by tribal people. Purpose of this study was to document the status and utilization pattern and to assess the economic value of NTFPs of the state. Present study was carried out in eight districts of Arunachal Pradesh viz., Changlang, East Kameng, Lower Subansiri, Tawang, Tirap, Upper Siang, West Kameng and West Siang covering 34 villages and 350 households. Altogether, 135 plant based and 36 animal based non-timber forest products were recorded. Among plant based NTFPs, 54 species were collected for leaves, 30 for stem and 22 for fruits. Most of the animal based NTFPs (93%) were collected/hunted for food. Average 20~40 kg of NTFPs was collected annually per household. Maximum plant based NTFP collection was recorded from West Siang followed by West Kameng and Tawang. Similarly, highest collection of animal based NTFPs was recorded from West Siang followed by Tirap and Lower Subansiri. NTFP contributed more than 50% of annual income of the people of East Kameng, Tirap, Lower Subansiri and Upper Siang districts. An illiterate and unemployed person with minimum agricultural land was more dependent on forests for his livelihood than a literate jobholder. The study concludes that a large section of people of Arunachal Pradesh are dependent on NTFPs for their livelihood however due to its unscientific harvesting, the availability of NTFPs is receding with time. There is an urgent need to promote cultivation and scientific harvesting of NTFPs in order to conserve the plant and animal diversity of this global biodiversity hotspot and for ensuring livelihood security of the people living in this area.

  • The purpose of this study is to observe the relationship between smoking and control factors to blood pressure, such as sodium and potassium levels of dietary intake and serum in 67 rural university male students(smoker: 35 persons, non smoker: 32 persons). 3-day dietary record and blood sampling were conducted for measurements of the levels of dietary intake and serum. The results were as follows: 1) There are no significance between smokers and non-smokers in height, weight, and BMI. 2) Mean systolic and diastolic blood pressure of smokers and non-smokers were $131.33\pm93.75mmHg, \;119.37\pm80.62mmHg, $ respectively. Blood pressure of smoker was higher than that of non-smokers(p<0.05). 3) There was no significant difference between smoker and non smoker in dietary potassium intake but dietary sodium intake and Na/K ratio of smoker were higher than those of non-smokers(p<0.05, p<0.05). And significant correlation was found between dietary sodium intake and blood pressure of smokers(p<0.05). 4) Smokers of optimum gustation of salt(0.52%) was higher than that of non-smokers(0.49%). Even though blood pressure of smokers was not critical level, if they smoke continuosely until middle age, their blood pressure will be increased by smoking. The results of this study suggest that no smoking education program for smokers including the information about desirable food habits for prevention of hypertension should be developed.

  • The importance of the standards and its related texts established by Codex Alimentarius Commission (CAC) had been increased by the Agreement of Application of Sanitary and Phytosanitary Measures (SPS Agreement) in World Trade Organization (WTO). To meet the needs of WTO SPS Agreement, biennial CAC meeting had been changed to every year. This study was conducted to analyze the effects on interval between CAC meetings. The years of adoption, revision and amendment of CAC texts were collected from the official standard list and individual texts from CAC homepage. The period since establishment of CAC was divided into four groups by starting negotiation of Uruguay Round, WTO foundation and reducing the interval between CAC meetings. The collected data were analyzed by SPSS program. The numbers of CAC standards, guidelines, recommendations, maximum residue levels, and miscellaneous texts were 202, 56, 46, 3 and 5, respectively. Since 8 documents didn't contain the adoption year, these texts were eliminated to analyze adoption year. For adoption, annually 11.26 texts were established since establishment of CAC and there were no significant difference among the 4 groups. However the average numbers of revisions and amendments of adopted texts for overall periods and for each period were 7.56, 0.93, 6.50, 17.20 and 19.75, respectively. The average numbers of overall decisions, defined as summation of adoption, revision and amendment of texts, for overall periods and for each period were 12.37, 6.27, 9.00, 17.40 and 29.25, respectively. There were significant differences by the WTO foundation and the interval between CAC meetings. The reduced interval of CAC meetings influenced to increase number of revisions and amendments of adopted texts, but not yet adoption of new text.

  • Efforts to have children consume milk continue across the world for the sufficient supply of calcium and protein. This study examines the frequency and amount of dairy milk and the recognition, acceptability, and knowledge of milk and dairy products by considering fifth- and sixth-graders in Hwaseong, Korea. The acceptability of milk and dairy products measured based on a five-point Likert-type scale was assessed to determine its correlations with breakfast frequency, the frequency of milk intake, and milk knowledge. According to descriptive statistics, 47% and 53% of the subjects were fifth- and sixth-graders, respectively, 53% and 47% were male and female, respectively, 45.3% and 51.2% had mothers in their thirties and forties, respectively, and 57% had working mothers. Breakfast frequency was 5.2 and 5.3 times per week, and milk and dairy intake was 4.6 times. The milk knowledge score was 5.3 out of 10 points. The average daily intake of milk was a cup (55.1%), and a vast majority preferred white milk (68.6%). Ice cream bar type (4.49 points) and cone type (4.48 points) showed the highest acceptability, and breakfast frequency was positively correlated with white milk and cheddar cheese (p<0.01). Daily milk intake frequency was positively correlated with white milk and fortified milk. Milk knowledge was positively correlation with white milk, fortified milk, functional yogurt (p <0.05), fermented milk, and cheese (p<0.01). The higher the breakfast frequency, the more likely the intake of white milk (p<0.01). An increase in milk intake increased milk knowledge (p<0.05). The higher the level of knowledge, the more likely the intake of fortified milk and the frequency of milk intake. These results suggest that school lunch milk may increase awareness and milk intake through continuing education in milk knowledge. High acceptability scores for white milk, fortified milk, and fermented milk indicate their suitability for school milk consumption.

  • This study is to find out the antioxidative effect and serum and liver lipid composition of wild grape juice in vivo. Forty 6-week-old white Sprague Dawley rats were divided into 4 groups such as normal lipid group, normal lipid group with wild grape juice, oxidized lipid (basic diet plus 10% of oxidative lipid) group and oxidized lipid group with wild grape juice, and 2ml juice was provided everyday. After 4 weeks of feeding with experimental diet each groups were examined for the antioxidant enzyme activity in blood and liver microsome and their serum and liver lipid composition. Glutanthione peroxidase activity in blood was significantly higher in oxidized lipid group with wild grape juice than in oxidized lipid group. Glutanthione peroxidase activity showed no difference depending on wild grape juice supplementation. Glutanthione peroxidase activity in liver was significantly higher in the groups with wild grape juice than in the groups supplemented only with oxidized lipid. Glutanthione reductase activity showed no difference depending on the supplementation of wild grape juice. Serum triglyceride level in the group supplemented with oxidized lipid diet and wild grape juice showed similar value to the normal lipid group and the normal lipid group with wild grape juiceoxidized fa6. Liver total lipid in the group supplemented with oxidized lipid and wild grape juice showed similar value to the normal lipid group and the group supplemented with normal lipid and wild grape juice. And it was lower than that of oxidative lipid group without juice. The liver triglyceride level in the group supplemented with normal lipid and wild grape juice was lower than that in the oxidative lipid group, but it was as low as in the group supplemented only with normal lipid.
