This study was conducted to investigate the dietary habits and nutritional knowledge of 5th and 6th graders and the teachers' perception of dietary life education at the elementary schools in Chuncheon area. The children who had breakfast and supper everyday accounted for 54.1% and 80.3% each. Children consumed 'breads or confectioneries'(42.6%) and 'fruits or juices'(39.3) as snacks. Only 57.4% of the children had balanced diet. Only 59% of the children answered correctly at the nutritional knowledge test, and only 75% had good dietary behaviors. About 78% of the teachers had the experiences of dietary life education, and they taught it in class(38.9%) or at school lunchtime(35.2%). The teachers answered that the major nutrition problems of elementary students were bad eating habits(37.7%) and too much ingestion of fast or instant foods(36.2%). They also answered that dietary life education was necessary(79.7%) and should be started more earlier(87.0%). Ironically, about 49% of the teachers answered that dietary life education should be taught by dietitians even if the teacher who spent most of the time with their students is the best person for dietary life education at school. It should be done in children's daily life, especially for elementary school students. Therefore, teachers should recognize the importance and the specialty of dietary life education at the elementary schools.

The study sought ways to promote the global recognition of Korean food items. The Korean cuisine is one of the healthiest and well-balanced foods in the world. There are world-wide sauces in the United States, China, Japan, Thailand, Vietnam and Cambodia, Singapore, Indonesia, India, Australia, British, France and Italy. The above mentioned countries have good sauces and marketing strategies. In contrast to those countries, the internalization of Korean-style sauce has not yet been carried out. In this study, globalization plans for Korean cuisine through Korean-style sauces are divided as follows: promotion of the existing Korean-style sauces such as soybean sauce, Gochujang, Doenjang and Ssamjang, to chefs in foreign countries; development of derivative sauces, based on Gochujang, Doenjang, and Ssamjang; overseas promotion of Korean-style sauces through foreign chefs in Korea; and overseas promotion of the existing Korean-style sauces. Development of indigenous sauces by Korean food manufacturers and processors is one route in the promotion of Korean cuisine. Korean franchising restaurants could also aid in export of Korean food items. The food manufacturing/processing sectors must work in concert with the Korean government to globalize the Korean cuisine. The government should play a leading role in fostering star chefs, holding Korean cuisine seminars along with promotional efforts in foreign countries and foreign cooking schools (such as the 'Taste Korea' campaign).

To prepare for the changes in the future, this study considered people in their seventies and eighties in rural areas in the last decade. Based on a survey of rural life by the Rural Development Administration, all factors were analyzed using SAS ver. 9.3. The rate of rice farming decreased, and vegetable-cultivation increased from 8.4% in 2001 to and 26.6% in 2008 for people in their seventies and eighties. The number of family members decreased to 1.96 in 2010 from 2.04 in 2001, and annual income increased by KRW 20-29 million for those in their seventies and eighties, whereas it was more than KRW 30 million for those in their forties. Bathing with warm water increased to 88.9% from 69.8%, and household waste treated by self-incineration decreased from 86.4% to 40.0% in the last decade. Separate collection spread since 2008. Food waste disposal and the burial (46.0%) showed had for people in their seventies and eighties, and animal feed increased (50.7%) for those in their forties at 2001. The separate collection increased by 39.6% in 2010 for those in their seventies and eighties and by 53.5% for those in their forties(p<0.05). The manufacture of jang and kimchi showed were little annual changes for people in their seventies and eighties. Food storage processing was higher for those in their forties. For those in their seventies and eighties, food group intake over the 2004-2010 period increased from 3.3 times a week to 4.2 times a week for protein foods and from 4.9 times a week to 5.5 times a week for vegetables. There was no change in fruits, milk, and seaweeds for those in their seventies and eighties, but there was an increase for those in their forties. The results suggest the continued increase in the manufacture of jang and kimchi and protein and vegetable intake for those in their seventies and eighties. Some direction to welfare, mechanized rice planting and living with neighbors together would be continued with good nutrition for elderly residents.

Cardiac troponin-I (cTnI), creatine kinase-MB (CK-MB), and C-reactive protein (CRP) are routine cardiac markers for the diagnosis of cardiovascular disease. Recently, brain natriuretic peptide (BNP) has garnered attention as a marker of heart failure. This study was retrospectively designed to investigate the relationships between preoperative BNP, other cardiac markers levels and perioperative parameters in seventy-four adult patients that underwent off-pump coronary artery bypass grafting (OPCAB) and to assess its usefulness for predicting postoperative outcomes. Preoperative levels of BNP, cTnI, CK-MB, and CRP had significantly positive or negative correlations with echocadiographic parameters. There were significantly positive relationships between BNP, cTnI, CK-MB, and CRP concentration. Postoperative mechanical ventilation time had a positive correlation to preoperative levels of cTnI, CK-MB, and CRP, while ICU-staying period had a positive correlation with BNP, cTnI and CK-MB. These results reveal that a preoperative level of BNP is a good predictor and that its combination with cTnI, CK-MB, and CRP might be useful for diagnosis and comprehensive risk stratification of patients with coronary heart diseases, as well as prognosis of perioperative outcomes in OPCAB patients.

It was performed to find out difference of the nutritional contents between chungjung chicken meats grown chemicals free and general chicken meats. The chungjung chicken was eat and given feeds of good quality mixed living microbial agent, power of ginseng leaves and by-product of extract liquefied sea foods from fishes producted clean area of the Western Sea, including plentiful calciums, amino acids, docosahexanoic acid(DHA) etc. Addition of they improved chungjung chicken yields and meat quality compared to general chicken given feeds mixed antibiotic etc. Also, chungjung chickens eaten miced type develop resistance to in disease. There were significant trend in crude proteins, calciums, crude lipids contents, and unsaturated fatty acids between the chungjung chicken meats and the general chicken meats. The crude proteins and calciums contents were higher in the chungjung chicken meats than the general chicken meats, but the crude lipids contents were higher in the general chicken meats than that. Also, contents of the n6 fatty acids and n3 fatty acids in chungjung meats were higher than that. Especially, contents of DHA in the chungjung chicken meats were detected higher than the general chicken meats. Therefore, the results from this experiments will provide a information for the nutritional knowledge of the 'white meats', especially the clean chicken meats.

Sweet potato-malt worts were prepared by using sweet potato paste of Shinyulmi and Shinjami as the main adjunct, enzymes, malt, hop, and water. We brewed low-malt beers of the lager- or ale-type by using these worts and inoculating bottom and top fermenting yeast, respectively. Moreover, the componential and functional characteristics of the resulting beers were evaluated. During saccharification of sweet potato, the addition of an enzyme agent containing ${\alpha}-amylase$ caused an improvement in filterability and an increase of total sugar. The sugar content of sweet potato-malt wort which was prepared by the addition of 0.1% enzyme agent containing ${\alpha}-amylase$ and a three-step infusion procedure was $13.5^{\circ}Brix$ adequate for beer brewing. The polyphenol and anthocyanin contents of Shinjami beer were increased with increasing content of the paste, and also increased DPPH and ABTS radical scavenging activities. But in Shinyulmi beer it were decreased. A strong correlation was obserbed between antioxidave activities and polyphenol and anthocyanin contents of sweet potato beers. In all lager- and ale-type low-malt beers using 41.6% of Shinjami pastes, sensory attributes very similar to those of 100% malt beer were obtained and they were very good as they had unique red color.

The question of how to establish sustainable agricultural systems has become as prominent as questions related to water, energy and climate change. High input/high output agriculture has brought with it many adverse effects; the massive deterioration of soil and water in both quantity and quality, increased greenhouse gas emissions and an increased prevalence of unsafe foods. Additionally, urbanization and climate change has worsened the shortage of farmland and reduced the supply of agricultural water. Given these challenges, maintaining, conserving and efficiently using agri-environmental resources, through fostering of sustainable agriculture, have emerged as key tasks in solving these problems. What is needed therefore is research, based on systematic and comprehensive empirical analyses, that can propose plans and methods for establishing an appropriate sustainable agricultural system. The empirical analysis of sustainable agricultural system is approached separately from economic, environmental and social aspects. An analysis of environment effect reveals that the available phosphate level is 1.3~2.1 times greater than the optimal amount in rice paddies, upland fields and orchards. Further examination has revealed that the excess nutrient is polluting both ground water and surface water. Analytical results for economic feasibility show that factors of production have been invested heavily in the rice crop. Under these conditions, sustainable agriculture, including low-input agriculture, appears to be a possible alternative that will facilitate simultaneous improvements in both economic feasibility and environment effects. Analysis results for sociality reveal that social factors include the value of producer, association and interior networks. Social conditions are comprised of leadership, consumers' awareness, education and conflict solutions. In addition, analysis as to the degree investments contribute to improving agricultural value added has revealed that the direct payment program is the most effective instrument. Experts confirm that economic feasibility can be improved by scientific and well-reasoned nutrient management on the basis of soil testing. Farmers pointed to 'economic factors' as being the largest obstacle to switching to the practice of sustainable agriculture. They also indicate 'uncertainty with regards to sustainable agriculture technology' as an impediment to practicing sustainable agriculture. Even so, farmers who believe environmental and regional issues to be the most pressing problems have expanded their practice of sustainable agriculture. The keys to establishing sustainable agriculture system are classified into the following four aspects. Firstly, from an economic aspect, the research indicates that agricultural policy needs to be integrated with environmental policy and that the function of market making based on the value chain needs to be revitalized. Secondly, from an environmental aspect, there is a need for an optimal resource management system to be established in the agricultural sector. In addition, sustainable agriculture practice will need to be extended with attendant environmentally-friendly and sustainable intensive technology also requiring further development. Thirdly, from a social aspect, green agriculture management needs to be fostered, technology and education extended, and social conflict mediated. Lastly, from a governance aspect, it will be necessary to strengthen good governance, assign and share suitable roles and responsibilities, build a cooperation system and utilize community supported agriculture.

Legumes are good sources of various nutrients. Among legumes, soybean and its flour are accessible foods to consumers. However, in case of soybean flour, there is a disadvantage of easily going rancid. Thus, this study aimed to investigate how the quality of soybean flour changes during storage according to the packaging materials and storage temperatures. The raw and roasted soybean flours were packed in two types of packaging, polyethylene (PE) and polypropylene (PP) film bags respectively, and stored at three different storage temperatures (4, 20, and $45^{\circ}C$) for 1 year. The acid value, conjugated diene value, peroxide value, p-anisidine value, thiobarbituric acid (TBA) value, lipoxygenase activity, and fatty acid content of raw and roasted soybean flours were measured at the point of starting storing, and after 1, 2, 4, 8, and 12 weeks of storage. The acid value of soybean flour was increased for 4 weeks and thereafter significantly decreased (p < 0.0001). The conjugated diene value was significantly increased after 4 weeks storage at $45^{\circ}C$ with PE and PP film bags (p < 0.0001). The peroxide value had no changes during 4 weeks storage at $45^{\circ}C$ with PE and PP film bags, and then those was dramatically increased after 8 weeks (p < 0.0001). The p-anisidine values in all of storage conditions were decreased after 4 weeks. Lipoxygenase activity was decreased at 12 weeks storage at $20^{\circ}C$ and $45^{\circ}C$ with PP film bags. Acid value had positive correlations with p-anisidine value (r = 0.30 and p < 0.0001) and lipoxygenase activity (r = 0.36 and p < 0.0001), and had negative correlations with conjugated diene value (r = -0.45 and p < 0.0001) and peroxide value (r = -0.25 and p < 0.001). Conjugated diene value had a high positive correlation with peroxide value (r = 0.76 and p < 0.0001), but that had a negative correlation with lipoxygenase activity (r = -0.51 and p < 0.0001). Peroxide value had negative correlations with p-anisidine value (r = -0.20 and p < 0.01) and TBA value (r = -0.15 and p < 0.05). The degree of reduction in fatty acid content of raw soybean flour was higher than the roasted soybean flour during the storage. Total fatty acid content had positive correlations with acid value (r = 0.45 and p < 0.0001) and p-anisidine value (r = 0.58 and p < 0.0001), but had a weak negative correlation with conjugated diene value (r = -0.19 and p < 0.01). This study showed how the rancidity of the raw and roasted soybean flours progressed during storage. Thus, our findings can be used as base data to do a further study of finding and developing more stable storage conditions of the soybean flour.

This study was performed to provide basic data of Cirsium setidens Nakai by cultivars that will be applied for development of functional foods and ingredients. We assessed pectiolinarin content, total flavonoids content and antioxidant effects (DPPH radical scavenging activity and ORAC assay) of C. setidens Nakai. Our results showed that the pectolinarin and total flavonoids contents of C. setidens Nakai by cultivars ranged from $3.95{\pm}0.05$ to $7.29{\pm}0.07mg/g$ and from $40.42{\pm}0.91$ to $76.70{\pm}2.24mg$ pectolinarin equivalent (PNE)/g, respectively. Among C. setidens Nakai by cultivars, the pectolinarin content was highest in GW-D extract. Futhermore, the DPPH radical scavenging activity of C. setidens Nakai ranged from 31.25 to 81.93%, respectively. The oxygen radical absorbance capacity (ORAC) value was highest in GW-D and GW-E extracts (514.49 and $501.73{\mu}M\;TE/g$, respectively). These results suggest that C. setidens Nakai extract could be considered as a good sources of natural antioxidants and functional food ingredients.

The purpose of this study is to determine the possibility of using Codonopsis lanceolata leaves as natural health food source. To accomplish this purpose, the contents of general and antioxidative nutrients of Codonopsis lanceolata leaves were measured. The contents of carbohydrate, crude protein, crude lipid and ash were 65.09%, 18.02%, 1.34% and 9.72%. And the calories of Codonopsis lanceolata leaves were 288.36 Kcal. The protein contained total 16 different kinds of amino acids. The contents of essential and non-essential amino acids were 5,906.41 mg and 7,551.56 mg, respectively. K was the most mineral followed by Ca, P, and Mg, which means Codonopsis lanceolata leaves are alkali material. Total phenolic contents of Codonopsis lanceolata leaves were 1.87 mg/g, and total flavonoids contents were estimated as 1.87 mg/g. Based on the above results, we deemed that the Codonopsis lanceolata leaves might have potential antioxdant activities. The general nutrients and other antioxidatant bioactive materials in Codonopsis lanceolata leaves were also potential materials for good health food. It is expected that a follow up study of Codonopsis lanceolata leavesthrough developing processed food and evaluation of their functional properties would provide useful information as a source of medicinal foods.
