  • The flora of vascular plants in the mountains located in the Uiryeong-gun area, in the South province of the Korean Peninsula, such as Jagul-san(897.1 m), 676 Highland(676 m), Byeokhwa-san(522 m), and the Bangeo-san(530.4 m), was investigated between April 2008 and August 2009. These investigations found 580 taxa consisting of 496 species, 1 subspecies, 77 varieties, and 6 forms, found within 319 genera under 103 families. The count totaled at 744 taxa(16.2% of all vascular plant taxa in Korea), which was made up of 648 species, 3 subspecies, 81 varieties, and 12 forms, found within of 362 genera under 109 families, when voucher specimens from the previous research studies were added. Forests of the investigated areas were generally composed of mixed Pinus densiflora and Quercus sp. The areas with comparatively excellent vegetation were the valley neighboring Baekun-sa(temple) (in the eastern slope of Mt. Jagul-san), the southwest slope of Mt. 676 Highland, the eastern slope of Mt. Byeokhwa-san, and the northern slope of Mt. Bangeo-san. 10 families were collected in abundance: Compositae, Graminae, Leguminosae, Liliaceae, Rosaceae, Cyperaceae, Labiatae, Polygonaceae, Ranunculaceae, and Violaceae these families made up 50% of all collected taxa. 19 taxa were endemic to the area, including Salix hallaisanensis H.Lev, S. koriyanagi Kimura, Aconitum austrokoreense Koidz, A. pseudolaeve Nakai, Clematis trichotoma Nakai, Thalictrum uchiyamai Nakai, Stewartia pseudocamellia Maxim, Philadelphus schrenkii Rupr., Lespedeza ${\times}$ robusta Nakai, Vicia chosenensis Ohwi, Euonymus trapococca Nakai, and Angelica cartilagino-marginata var. distans(Nakai) Kitag. Eight of the taxa were rare and endangered plants, as designated by the Korea Forest Service, including Jeffersonia dubia(Maxim.) Baker & S. Moore and Viola diamantiaca Nakai. 38 taxa of alien plants were found. Vegetation of the surveyed areas falls in the South province of the Korean Peninsula. Of all the taxa collected, 463 taxa(10.06% of all vascular plants in Korea) are considered useful plants, 231 taxa are edible, 193 taxa have medicinal uses, 65 taxa are used ornamentally, 234 taxa are important forage, 3 taxa are used as an industrial raw material, 17 taxa are used for timber, 18 taxa contain useful dyes, and 7 taxa are used for fiber.

  • This study was carried out to investigate the self-reported health and eating habit of the elite female adolescent athletes in Incheon. The subjects were 102 elite female athletes of middle and high schools located in Inchon. A self-administered Questionnaire was used for this cross-sectional survey. Statistical analysis by two-way ANOVA was performed to discriminate between the main effects of age (as middle and high school athletes) and sports type, and their interaction. As use of nutritional supplements, 35.8% of the total subjects took vitamin and iron supplements and 62.5% of field and track athletes took vitamin and iron supplements. While mental stress related to exercise was much in fencing > shooting > field and track > swimming athletes, physical burden during training was higher in swimming > field and track > fencing > shooting athletes. More than half of the subjects showed irregular menstrual cycle. As the most severe problem of eating habit, they reported skipping meal > overeating > prejudiced meal > preference to salty and spicy foods. More than half of the subjects skipped meal over three times per week. Fencing and shooting athletes showed very significantly higher frequency of skipping meal and more irregular breakfast time compared to those of other sport types. As for snack, they ate cookies, carbonated drink, chocolate, candy > milk, yogurt, ice cream > cake, bread, rice cake > fried noodle > hamburger, pizza. Therefore, nutritional counseling and education by sport type are necessary for health and good eating habit of these elite female adolescent athletes.

  • This study was carried out to investigate the effects of nutrition education on blood glucose in type 2 diabetic patients with low income. There were 50 (27 male and 23 female) study subjects with type 2 diabetes under national medical support, and the monthly income in most of them was less than 500,000 won. Anthropometric measurement, biochemical blood indices, food intake, dietary habits, and nutrition knowledge of the subjects were investigated before nutrition education. Nutrition education was conducted 6 times within 12 weeks. After nutrition education, the glycosylated hemoglobin was significantly decreased (male: $8.4{\pm}1.6%$ to $8.0{\pm}1.7%$, female: $8.3{\pm}1.6%$ to $8.0{\pm}1.3%$) and the total cholesterol was also significantly decreased in both groups. The group of female resulted in a significant decrease in fasting blood glucose ($169.7{\pm}28.2$ mg/dL to $152.8{\pm}22.0$ mg/dL) and triglyceride ($177.8{\pm}56.3$ mg/dL to $162.3{\pm}36.1$ mg/dL), but the group of male did not show a significant decrease in fasting blood glucose and triglyceride. Nutritional knowledge and dietary habit scores of the subjects were significantly improved after nutrition education. The results demonstrate that nutrition education for type 2 diabetic patients with low income are effective in improving their blood glucose.

  • The purpose of this study was to compare the trophic structures and the energy flows in the Lake Namyang and the lower reaches of the Nakdong River using the Ecopath model. The sampling and analyses were carried out at 6 sampling sites of the Lake Namyang and the lower reaches of the Nakdong River respectively on March and November in 2007. As a result, the Lake Namyang was consisted of producers(Detritus, Macrophytes, Phytoplankton), primary consumers(Zooplankton, Zoobenthos, Carassius cuvieri, Carassius auratus, Other fishes) and secondary consumer(Cyprinus carpio, Pseudobagrus fulvidraco) and the lower reaches of the Nakdong River was consisted of producers(Detritus, Macrophytes, Phytoplankton), primary consumers (Zooplankton, Zoobenthos, Cyprinus carpio, Hemibarbus labeo, Other fishes) and secondary consumer (Micropterus salmoides). The food-chain length of the Lake Namyang was relatively short when compared with the lower reaches of the Nakdong River. The shortness of food-chain length in the Lake Namyang could be attributed to the low biomass of the top predators. The total system throughput of the lake Namyang was estimated at 14.3 kg $m^{-2}\;year^{-1}$ including a consumption of 39.0%, exports of 21.0%, respiratory flows of 12.0% and flows into detritus of 28.0% and the total system throughput of the lower reaches of the Nakdong River was estimated at 2.8 kg $m^{-2}\;year^{-1}$ including a consumption of 52.0%, exports of 9.1%, respiratory flows of 18.0% and flows into detritus of 20.9% in the lower reaches of the Nakdong River.

  • Community structure of fish and inhabiting status of natural monument and endangered species, Cobitis choii were investigated in the Baekgok Stream, a tributary of the Geum River drainage system of Korea from May to November 2012. Ten-15 fish species inhabited upper stream (St. 1~St. 3) with a Aa or Aa-Bb river type composed of mostly pebble and cobble bottoms. 15~21 species did middle stream (St. 4~St. 5) with Aa or Aa-Bb type composed of mostly cobble, boulder and pebble bottoms. Nine species did Reservoir Baekgok (St. 6) with composed of mostly mud bottoms, and Seven species did Reservoir Baekgok outflow (St. 7) with Aa-Bb type composed of mostly boulder and cobble bottoms. And 20~23 species did lower stream (St. 8~St. 9) with a Bb-Bc type composed of mostly cobble and sand bottoms. A total of 35 species belonging to ten families were found in the stream during the survey. The dominant species were in the order of Zacco platypus (34.7%), Pungtungia herzi (9.4%) and Microphysogobio yaluensis (9.0%). Other abundant species included Tridentiger bifasciatus (8.2%), Pseudogobio esocinus (5.9%), Carassius auratus (4.6%), Squalidus chankaensis tsuchigae (3.7%), Rhinogobius brunneus (3.0%). Among residing species, ten (28.6%) species were endemic to Korea, one (Cobits choii) was endangered, and two (Micropterus salmoides and C. cuvieri) were non-indigenous. Natural monument and endangered species, C. choii were only inhabited St. 5, and they are inhabited 30~100 cm in water depth, sand bottom and slowly velocity. Using the mark-recapture method, populations were estimated at $7,838{\pm}6,290$ individuals. Age group in May estimated from total length indicated that the 38~45 mm group is 0 year old, the 46~60 mm group is 1 years old, the 61~80 mm group is 2 years old, and the 81~93 mm group is more than 3 years old. Condition factor (${\times}10^5) was 0.36~0.39 and 0.35~0.38 for female and male, respectively, and they are 13.5% were infected with parasites (digenea). We are discussed the health status, threats and conservation strategies of C. choii in the Baekgok Stream.

  • The predeccessor of Danjanjinja was Myorak temple which is built in the 7th century. At that age, the Buddhist culture of Japan had highly prospected by transmitting Buddhism to Japan from Han peninsular On the other hand, the private god of Fujiwara family in Danjanjinja is Uchigami which is one of typical Japanese popular belief like Dangshin of Korean's. Through these historical background, it could by presumed that the Kakitsisai might be the original form of Korean Buddhist sacrificial offerings from ancient age. So this study on Kakitsisai what had handed down from generation to generation about for 1300 years help us to study and estimate the ancient dietary culture of Korean and Japanese. 1. Kakitsisai performed high filling method in the sacrificial offerings like Kasuga, Horyuji and Korea. 2. The patterns and colors of high filling offerings are various in Korea and Japan. 3. They used unpolished rice by ancient rice, and called red and black one. We can guess both of countries ate unpolished rice at that age. 4. They used many kind of ancient wild fruits and vegetables. We could recognize what the ancients had eaten the foods.

  • The purpose of this study is to provide fundamental information for snack development contributing to physical growth of children with cerebral palsy. The study was conducted on the children with cerebral palsy of age 1 to 7 by investigating their food behavior, physical growth development, nutritional status, and snack intake. As a result of assessing physical growth by WLI (Weight-Length Index), the proportions of the children with cerebral palsy were the following: underweight 45.5%, normal 45.5%, overweight 6.0%, and obesity 3.0%. The mothers of the children with cerebral palsy mainly bought milk and dairy products for their children's snacks (43.5%) as well as fruits (33.3%). They wanted development of new snacks that helped growth development (50.5%), and preferred more development of the following snacks: Korean rice cakes (47.5%), biscuits (24.2%), bread (22.3%). The result of dietary intake showed that the percentage of RI in zinc and folic acid did not reach the RI in every age categories. The proportion of subjects with less than 75% of RI was 76.8% for the zinc and folic acid, and 52.4% for the calcium and iron. These results indicate that children with cerebral palsy had slower physical development and lesser nutrition intake than normal children. Hence, this study provided the basis to develop the snack for the malnutrition state children with cerebral palsy which helped their physical development. The shape of new snack considered was a rice cake which included zinc and folic acid that were insufficient in RI in children with cerebral palsy.

  • In an attempt to improve the taste and storage characteristics of Sulgidduk, a Korean traditional rice cake product, baekbokryung(White Poria cocos Wolf) powder was supplemented as one of the ingredients and Product Quality waw assessed. The baekbokryung Powder was added in rations of 0, 5, 7, 10, and $15\%$(w/w) per rice powder during the raw material preparations. The sensory, objective quality, and microbiological characteristics of the products were examined at 4-hr intervals during storage for 36 hours at $20^{\circ}C$ The sensory evaluation was conducted based on the acceptability and intensity characteristics of the product. In the acceptability test, a $5\%$ treatment wae renerally ranked with the highest score, among all the treatments while the preference differed according to ages of the panels ; namely, those in their 20's to 30's liked a $5\%$ supplementation while those in their 40's to 60's Preferred a $7\%$ one. The addition of baekbokryung Powder proportionally decreased the moisture content of the products. The colorimetric redness(a) and yellowness(b) of the Products increased with increasing added baekbokryung Powder. The redness values began to decrease slowly from the beginning while the rates were accelerated after 8 to 12 hours of the storage. In the textural characteristics, hardness, gumminess and adhesiveness values increased with increasing added baekbokryung powder. The rapid increase in adhesiveness during the initial 4 hour of storage and the following stabilization was noted. Cohesiveness and springiness values tended to decrease gradually with increasing added baekbokryung Powder. Except for the control sample, no significant differences in the total microbial counts among the treatments were noted. After 20 hours of storage, the control sample exhibited a rapid increase in total microbial count, while the Proliferations of microorganisms were rather suppressed in baekbokryung Powder treatments according to the added amounts The results of the study support the benefits of baekbokryung powder supplementation in Sulgidduk in the aspects of taste and functionality. The degree of further increase of baekbokryung Powder in Sulgidduk without causing the adverse qualify effects remains for future study.
