  • Much attention has been focused on the activity of the natural antioxidants present in fruits and vegetables, because potentially these components may reduce the level of oxidative stress. Especially, mulberry leaves containing many natural components are considerable resource for natural antioxidants. The antioxidant capacity of mulberry leaves was investigated with minilum L-100 device and ARAW-KIT (anti-radical ability of water-soluble substance), in comparison to the ascorbic acid. The antioxidant capacity of 16 varieties was 3303.4 nmol at opening stage of five leaves in spring. The highest stage of antioxidant capacity (3708.0 nmol) and yield rate was just before the coloration stage with anthocyanin in fruits, whereas the lowest stage was middle of June (2231.6 nmol) and about two months growing stage after summer pruning (2064.6 nmol). But after summer pruning, the antioxidant capacity of mulberry leaves increased gradually until just before fallen leaves stage. Even if samples were same variety, antioxidant effect of those showed different results according to collected regions. Also, antioxidant effect of mulberry leaves were higher than that of branches. The antioxidant capacity of yield-type mulberry leaves and fruits (Morus alba L., M. bombycis Koidz, and M. Lhou (Ser.) Koidz) collected from In-je, Won-ju and Yang-yang regions, Kang-won province, Korea, was investigated. The results indicated that total antioxidant capacity of yield-type mulberry leaves was 2711.2 nmol. In the antioxidant capacity analysis of Jeollabuk-Do genetic resources, autumn's mulberry leaves showed higher antioxidant capacity than that of spring's it. To investigate the effect of tea on antioxidative capacity, five kinds of tea(coffee mix, green tea added brown rice, mulberry leaf tea, Polygonatum odoratum tea and black tea added lemon) were selected and analyzed. Their's anti-oxidative capacity were 2,531.01 nmol, 1,867.42 nmol, 1,053.72 nmol, 292.71 nmol and 188.91 nmol, respectively. The antioxidative capacity of drinking water soaked with mulberry leaf showed 891.96 nmol.

  • 1. 선행 연구에서 염색체 3번의 RM60~RM231 부근에서 종자중, 수당립수에 관여하는 QTL이 탐지되었고, 이를 확인하기 위하여 이 지역에 크기와 위치가 다른 O. glaberrima 단편이 이입된 5 계통을 선발하여 표현형을 조사하였다. 실험 결과 계통별로 출수기, 임실률, 수당립수, 종자중을 제외한 형태적 특성들이 밀양23호와 비슷한 양상을 보였다. 이는 대부분의 염색체 지역이 밀양23호로 회복되었기 때문이라고 보여진다. 2. 유전자의 위치를 자세히 알기 위해 RM60과 RM22 부위에 위치하는 SSR 마커를 이용하여 5개 계통의 유전자형을 검정하였다. 종자중과 수당립수에서 차이를 보이는 4계통, IL3, IL26, IL25와 IL51을 비교한 결과 종자중과 수당립수를 조절하는 유전자는 RM60-RM523 사이의 재조환 지점과 단완 끝 부분 사이에 위치하는 것으로 판단되며 그 거리는 약 1.2-Mb이다. 3. 본 연구에서 탐지된 연관된 종자중과 수당립수 QTL은 재배벼의 수량성 증진에 효과적으로 이용될 수 있을 것으로 판단된다.

  • The purpose of this research paper is to examine, from an ethnological viewpoint, the traditional practice of using sacrificial game and domestic livestock as is often seen at communal rites in Korea. This paper also examine how the more convenient use of livestock sacrifice developed from that in which wild game were once offered, and how this change in the type of animals used affected the significance of the sacrifice. It also looks at how the use of animal sacrifice for ceremonies eventually influenced the practice of meat consumption on the part of the participants in their daily life, and how it contributed to the eventual establishment and development of livestock breeding for the purpose of meat consumption. The practice of catching wild game in the mountains for sacrificial purposes eventually gave way to the use of pasturage cattle, but it should be understood that these domesticated livestock were raised primarily for ceremonial rather than meat consumption purpose. When used for sacrifice, these cattle were not castrated, as is normally done when they are slaughtered for meat consumption, but it should not be assumed that this was done for purposes of simplification. In addition, not only rice farmers but also when enterpreneurs set up a new enterprise, animal sacrifice was viewed not only as a form of on-site purification of evil, but also served the dual purpose of enhancing their business through the traditional custom of serving meat to those invited guests in attendance. In the large-scale village communal rite of Hwaghae Province located in the northwestern part of Korea, animal sacrifice was carried out in the ritual for the Mountain God in a highly dramatic style, and suggests that it originated with the agrarian rites of the "fire-field" farmers of East Asia, which were utilized to foretell whether the coming year would be one of abundance or famine, and to the royal ceremony held on the 3rd day of the 3rd month of the lunar calendar, as well as that held for the God of the Mountains and Streams. The dramatic-style hunting rite, included in the large-scale communal ritual of Hwanghae Province mentioned previously, as well as in the Ritual of the Cow from Pyungsan, also located in Hwanghae Province, in which wild game were used as sacrifice, is significant in that it points up the changes that have occurred in ceremonial animal sacrifice. However, more research on ritualistic animal sacrifice is still called for in rites for good farming, fishing, and the variety of others that are held throughout Korea.

  • Objectives: The purpose of this study was to compare and analyze e-commerce food purchase behavior and the perceptions of adult women according to their household types. Methods: The e-commerce food purchases of 318 adult women were surveyed and analyzed according to their household types (one-person or couple household (OCH); a household with children (HC); a household with parents (HP)). Results: The total amount of food purchases over 6 months through e-commerce according to household types was in the descending order of OCH (60.3%), HC (57%), and HP (55.1%) thus showing a significant difference (P < 0.05) in behavior between household types. The reasons for purchasing food through e-commerce included: a lower price than offline (30.8%), convenient delivery and transportation (30.2%), and food diversity (21.1%). When purchasing food online, the most important factor was price and quality, followed by quick and accurate delivery for OCH, exact information given about the product for HC, and recommendation from other consumers for HP (P < 0.01). The main foods purchased through e-commerce were coffee, tea (42.1%), instant and frozen foods (39.9%), water, beverages, dairy products (37.7%), snacks, bread, rice cakes (31.5%), and functional foods (27.4%). The percentage of respondents who were very satisfied or satisfied with their e-commerce food purchases was HP (84.1%), OCH (69.9%), and HC (65.6%) in that order (P < 0.05), and 96.5% of all subjects stated that they would be willing to purchase food through e-commerce in the future. The advantages of purchasing food through e-commerce were seen to be the highest in order and payment convenience with 4.1 points out of 5, followed by low price (4.0), variety of products (3.9), and ease of food purchase (3.9). Among the disadvantages listed, concerns about product damage and deterioration during delivery and differences between the displayed product and the delivered product were the highest with 3.7 points. Conclusions: The characteristics and perceptions of female consumers according to household types are important factors in enhancing the reach of e-commerce, and in preparing guidelines for food selection through e-commerce.

  • Objectives: The number of schools offering school lunches has increased in China. This study examined the dietary quality of the lunches consumed by Chinese school-age children and adolescents, with a focus on comparing school lunches with home lunches. Methods: The first weekday 24-hour dietary recall data of 6~17-year-old students (n=1,084) from the 2011 China Health and Nutrition Survey were analyzed. The subjects were divided into the school lunch group and the home lunch group, and the dietary quality of lunches was compared between the two groups among 6~11-year-old students (n=634; 177 in the school lunch group and 457 in the home lunch group) and 12~17-year-old students (n=450; 144 in the school lunch group and 306 in the home lunch group), respectively. Frequently consumed foods, amount of food group intake, food group intake pattern, Dietary Diversity Score (DDS), and Dietary Variety Score (DVS) were examined. Results: The most frequently consumed foods in both lunch groups were rice and pork. An excessive intake of meat and insufficient intake of seafood were noted in both lunch groups. The school lunch group showed a lower level of vegetable consumption than the home lunch group (P=0.017 in 6~11-year-old students, P=0.003 in 12~17-year-old students). Although more students ate meals with a better dietary pattern in the school lunch group than the home lunch group, there were no significant differences in DDS and DVS between the two groups. Conclusions: Overall, the dietary quality of lunches was not superior in the school lunch group compared to the home lunch group. This suggests that much room remain for improving dietary quality of school lunches in China.

  • This is the report of a food consumption survey of 193 members of 30 farm families in three rural villages of Korea. From a total of 188 households of the three villages, namely Wolgok in Kyunggi Do Province, Wachon in Kangwon Do Province, and Sobong in Cholla Namdo Province, 30 households were chosen for the survey. Four consecutive seasonal surveys, beginning in the autumn, November 1974 and finishing with the summer, August 1975, were made and each survey covered three consecutive days. The Precise Weighing Method was used in evaluating the kinds of food and nutrient intakes of the subjects. This method entails the accurate weighing of all foods by the investigator just prior to their consumption by the subjects under investigation. This survey was male to determine the actual food eaten by the members of these farm families at each season of the year, and to note any special differences in the foods consumed. The results obtained are summarized as follows: Food Intake The traditional ordinary diet of Korean farmers consists mainly of rice and other cereals as staple foods, and simple subsidary foods. The nutritional shortcomings of rice as a staple food are evident in the subclinical status of nutritional deficiencies. The mean consumption of cereals and their products was very high and it was more than half of the daily total food intake throughout all the seasons. The consumption of animal food, fruits, and fat by the farmers was very low. Fruit intake during winter and spring was almost nil. One of the special foods in the Korean dietary pattern is Kim-chi, a variety of pickled and fermented vegetables. The mean intake of Kim-chi during autumn and winter was very much higher than the other seasons. Korean farmers have difficulties in balanced year-round supply of food due to seasonality of food production and lack of food preservation. As nutrition problems of Korean farmers are highly influenced by seasonal variations, the expansion of an appropriate food preservation and storage programme should be encouraged. Special consideration should be given to new methods of preservation, the types of foods preserved, and production and consumption of nutritionally valuable foods for the improvement of the nutritional status in rural communities. Nutrient Intake Average adult rates for calorie and protein in the three study areas were 0.80 and 0.87 respectively, with little variations by villages. The adult caloric intake in averaged 2,928 kcal for autumn, 2,662 for winter, 2,673 for spring, and 2,760 for summer. Cereals contributed most of the total calories. In terms of the recommended daily dietary allowances for the Korean given by the Korea FAO Association, the diets in this survey were adequate except in the winter and spring. The protein intake averaged from 76.4 grams in autumn to 83.4 grams in summer and was near the recommended allowance, but a relatively large proportion of the total protein came from cereals and their products. The fat intake was unsatisfactory, ranging from 19.2 grams to 29.3 grams for the four seasons, and the consumption during farming season was higher than other seasons. It is apparent that the diet of the Korean farmers should be supplemented by calcium during autumn and winter. The highest calcium intake, with a mean of 583.5 milligrams, was recorded in summer. The mean intake of iron ranged from a low of 9.2 milligrams in the autumn to a high of 15.0 milligrams in the spring and it was satisfactory for all seasons. Among the vitamin group, the daily average intakes of vitamin A, thiamine, riboflavin, and ascorbic acid were lower than the desired intake throughout all the seasons. The mean vitamin A intake as ${\beta}-carotene$ ranged from a low of 2,807.8 IU to a high of 5,221.0 IU. The thiamine intake ranged from 0.98 milligrams to 1.19 milligrams, while mean riboflavin intake ranged from 0.92 milligrams to 1.13 milligrams. Ascorbic acid intake was 37.3 milligrams, the lowest, and the highest 47.8 milligrams. Niacin intake among Korean farmers was higher than the recommended allowance throughout all the seasons, and the mean intake ranged from 18.3 milligrams to 25.8 milligrams. The main character of the Korean farmers' diet has been found low in quality of protein and high in carbohydrate. Attention should be paid to the low intake of vitamin A, thiamine, riboflavin, and ascorbic acid among Korean farmers.
