It has been believed that the human body can be effected by color, sound, smell, and taste - each of them is based on the original character. Out of these elements, the color can be a mediation that absorbs energy into human body and adapts it to the creatures whose life are definitely based on the solar energy. This thesis makes a study of the possibility of applying the color to the oriental medical science by researching the color psychology and therapy which are studied in the west medical science, the recognition and application of color developed from orientalism, and the opinion of color in the oriental medical science. Color therapy is one of the psychological treatment techniques that are able to recover and maintain the health with the rays of the sun rays and the color. The light and the color have its energy that may relax, harmonize, encourage, or excite a human being. This is because the wavelength and the vibration of each color will take effects to human body. The core energy of absorbing and distributing the color vibration is made in the 7 "chakras" in the body, which are the pith and marrow of bio-energy directly connected with the center of the nervous system. There are several methods in the color therapy - the treatment of solar ray, the color-bath, the water-therapy using color energy, the inducement of the solar energy into the body, the acupuncture, the therapy of crystal and jewel, and the self-suggestion dependent upon the color. The color therapy can help us to keep our balance by changing the emotion into the positive energy that will cure the disease with color. As a result, this method not only must be useful to cure physical disease, or develop into good health but also will be used in conforming itself to the mental disease. The color therapy mainly uses the eight colors, which are made by mixing Red, Yellow and Blue basic colors in the field. They are never used in the treatment, but they will go along with complementary colors. This rule is closely connected with the theory of yin and yang which lies at the root of oriental philosophy, and with the treatment principle of oriental medical science whose field is focused on the balancing the body mentally as well as physically. In the East, it is the Obangsaek - the color of blue, red, yellow, white, and black in the theory of yin and yang and the five elements that have been used in helping people having trouble with their health for a long time. In the view of the oriental medical science, these five colors attached the theory of five-elements have been very useful to the physiology, the pathology, or the diagnosis, and been applied to the medical treatment, combining themselves with a five-taste in medicinal herbs. Since the study of color and human physiology has been made in some different interest and fields these days, it goes to prove that the different function of color we couldn't have got before becomes very useful to the medical science. The color must be worth researching the diversity for applying itself to the oriental medical science.

During 2008~2009 winter season, yellow patch and gray snow mold occurred on turfgrass plants in golf courses in Kangwon and Jeonbuk provinces, respectively. The fungi associated with the diseases were identified as Rhizoctonia cerealis Van der Hoeven and Typhlua incarnata Lasch ex Fr., based on the morphological characteristics of hyphae and sclerotia. R. cerealis and T. incarnata were pathogenic to most turfgrass and crop species tested. R. cerealis infected crown, stem and leaf tissue of the host plants, and the symptom was light yellow circular patch. Individual infected leaf near the margin of patch developed red color first and finally turn brown. The symptoms caused by gray snow mold pathogen are water-soaked spots, and became a watery soft rot. Infection parts became yellow and then turned brown followed by death of the whole plant. White mycelia were developed on higher petioles, leaves, and on soil where these plant parts lay, and black sclerotia of variable size and shape formed in the mycelial mass. All isolates tested were pathogenic on most turfgrass and crop plants, and significantly different in aggressiveness. Disease severity increased with longer snow cover days on target plants, suggesting that disease severity was expressed over snow cover days. There were significant differences in disease severity among the graminious species, and among cultivars within each species, indicating varying levels of susceptibility to R. cerealis and T. incarnata.

Length and weight relationship (LWR) for dominant Antarctic fishes was determined in two species of the family Nototheniidae; black rockcod (Notothenia coriiceps) and marbled rockcod (Notothenia rossii). Samples were caught in the offshore sea around King Sejong station located on King George Island, Antarctica in January, 2017. A total of 30 N. coriiceps and 7 N. rossii were caught by fishing rod and hook. Average total length was 266.0 mm for N. coriiceps and 275.4 mm for N. rossii. Average total weight was 283.1g for N. coriiceps and 290 g for N. rossii. In terms of LWR and b value, the results showed that both two species had positive allometries (b>3) in good health. This size information of two dominant Antarctic fishes would be useful for future physiological studies to understand of adaptation mechanism and biological pathway of Antarctic marine organisms.

To determine the properties for juice preperation of Black Omija (Schizandra nigra Max.) and Omija (Schizandra chinensis), yield of extraction, chromaticity and lightness, pH and soluble solid of the extract were investigated. The rate of extract yield from Schizandra nigra was highest when extracted for 3 hours at 80$^{\circ}C$ in 20％ ethanol solution. For the desirable chromaticity coordinates, the optimum extraction time and temperature of Schizandra nigra extract were 3 hours at 80$^{\circ}C$. The lightness of the extract was low of the value when extraction time and temperature was long and high. The sugar content of the extract of S. nigra was 2.0­2.6％ Brix, lower than that of S. chinensis, but the difference was insignificant. The pH of the extract from S. nigra was 0.1­0.2 higher than that of S. chinensis. Although the pH of the extract from S. nigra was a little low when extracted by water, the pH range was enough to maintain the stability of color of extract from the S. chinensis.

The importance of genetic resources conservation and utilization for economy and the health and well-being of societies in general is recognized all over the world. Mulberry genetic resources contain many natural components and are considerable resource for functional sericulture. We carried out antioxidative capacity analysis of mulberry leaves that were collected from Korea and some of foreign countries and preserved in the greenhouse. The mean antioxidant capacity of 34 accessions was 892.30nmol(ascorbic acid equivalent). Also we evaluated fruity characteristics and selected 4 accessions as breeding resources for the production of mulberry fruit. 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 antioxidative capacity were 2,531.01nmol, 1,867.42nmol, 1,053.72nmol, 292.71nmol and 188.91nmol, respectively. The antioxidative capacity of drinking water soaked with mulberry leaf showed 891.96nmol.

Seasonal changes in nutrients and suspended organic particulates were measured in the estuary of Nak-dong River in relation to the black laver bed. Monthly measurements of water temperature, pH, dissolved oxygen, nutrients ( $NH_4$-N, $NO_2$-N, $NO_3$\-N, $PO_4$-P and $SiO_2$-Si) and organic suspended particulates (organic carbon and nitrogen) were determined at five stations from February through December, 1970. PH varied 7.6-8.4 with an average of 8.0, and percent saturation of dissolved oxygen were 71-147% with an average of 100.8%. Studies gave evidence that Nak-dong River estuary is strongly enriched with nutrients. Concentrations of nutrients were: 0.13-12.54 ${\mu}g$-atoms/${\iota}$ (averaging 1.63 ${\mu}g$-atoms/${\iota}$) for $NH_4-N$, 0.12-2.09 ${\mu}g$-atoms/${\iota}$ (averaging 0.71 ${\mu}g$-atoms/${\iota}$) for $NO_2-N$, 3.46-56.79 ${\mu}g$-atoms/${\iota}$ (averaging 21.54 ${\mu}g$-atoms/${\iota}$) for $NO_3$-N, 4.04-57.90 ${\mu}g$-atoms/${\iota}$ (averaging 23.79 ${\mu}g$-atoms/${\iota}$) for total soluble nitrogen, 0.18-5.05 ${\mu}g$-atoms/${\iota}$ (averaging 0.96 ${\mu}g$-atoms/${\iota}$) for $PO_4$-P, and 18.33-133.29 ${\mu}g$-atoms/${\iota}$ (averaging 71.57 ${\mu}g$-atoms/${\iota}$) for $SiO_2$-Si, respectively. These nutrient levels were considerably higher compare with other productive laver beds of Wan do and Pyung-il Do in Korea or Ise Bay in Japan. Concentrations of suspended organic particulates varied 55-648 ${\mu}g/{\iota}$ (averaging 392 ${\mu}g/{\iota}$) with organic carbon, 30-155 ${\mu}g/{\iota}$ (averaging 92 ${\mu}g/{\iota}$) with organic nitrogen, and its carbon-nitrogen ratios were varied within 1.5-8.4 with an average of 4.6.

Contents of water soluble vitamin $B_6$ in a total of 62 agricultural products cultivated in local areas in Korea were analyzed by high performance liquid chromatography with fluorescence detector (HPLC/FLD). To verify the method of vitamin $B_6$ analysis, a quality control chart was formulated with in-house control using a mixture of broccoli and shiitake mushrooms. Among cereals, high content of vitamin $B_6$ measured $234.3{\sim}260.3{\mu}g/100g$ in dried mung bean and soybean. Vitamin $B_6$ content of non-glutinous and glutinous black rice measured $105.0{\mu}g/100g$ and $129.7{\mu}g/100g$, respectively. In vegetables, high content of vitamin $B_6$ were measured in passion fruit ($104.3{\mu}g/100g$), gat ($55.7{\sim}84.3{\mu}g/100g$), gomchwi ($31.3{\sim}88.0{\mu}g/100g$) and garlic ($72.7{\sim}98.3{\mu}g/100g$). Among fruits, gold kiwi 'Zespri' and green kiwi 'Hayward' revealed high vitamin $B_6$ content of $116.3{\mu}g/100g$ and $78.7{\mu}g/100g$, respectively. In persimmons, daebongsi had high vitamin $B_6$ content ($36.0{\sim}72.7{\mu}g/100g$) than bansi and sweet persimmon. Vitamin $B_6$ content in dried jujube and persimmon increased more than $86.7{\mu}g/100g$ compared to fresh materials. Among specialty crops, green tea powder ($64.7{\sim}251.0{\mu}g/100g$) and sansuyu ($172.3{\mu}g/100g$) revealed high content. Of mushrooms, vitamin $B_6$ content of Sparassis crispa ($139.3{\mu}g/100g$) was the highest. Vitamin $B_6$ content information of agricultural products in local areas in Korea collected from this experiment will be used as valuable preliminary data for grasp national nutritional status.

Using aqueous solution of 60% ethanol, the isoflavones contained in the Soybean (Chungsun, Korea), Tawon (Suwon, Korea), Jackbean (Hongsung, Korea), Soybean (Jilin, China), Black Soybean (Jilin, China), Kidneybean (Jilin, China) and Soybean (California, U.S.A.) were extracted. In this work, the pretreatment step was composed of agitation extraction, filtration, concentration, ultracentrifuge, and membrane filtration. The analysis by $C_{18}$ column was performed, and the mobile phase applied was linearly changed with A/B of 85/15-65/35 vol% for 50 min (A water/acetic acid, 99.9/0.1 vol%, B acetonitrile/acetic acid, 99.9/0.1 vol%). Among the soybeans tested, the total amounts of the four isoflavones (daidzin, genistin, daidzein, and genistein) extracted by the soybeans from Korea, China and U.S.A. were 1.37, 1.60, and 2.25 mg/g, respectively. It was also found that the total amount of aglycone of daidzein and genistein from soybean (American California) was $144{\mu}g/g$, which was the largest for the soybeans experimented.

From 2014 to 2016, approximately 5% of okra fruit were observed displaying gray mold symptoms at the research field of Jeollabuk-do Agricultural Research and Extension Services, Korea. The symptoms observed were water-soaked, brown or gray spots, and abundant mycelial with conidia appearing on the infected fruit. Initial infection commenced from the base of fruit and gradually moved to the pod, where it finally resulted in collapse. Colonies on potato dextrose agar were gray to grayish brown, felted and cottony expanding 65-80 mm after one week. The fungus formed several black sclerotia ranging $1.0-3.5{\times}0.5-3.0mm$ on the Petri dish after two weeks. The conidia were one-celled, ellipsoidal or ovoid, colorless or pale brown, and $6.2-15.4{\times}5.0-10.4{\mu}m$. Conidiophores arose solitary or in groups, straight or flexuous, septate, with an inflated basal cell brown to light brown, and measured $85-450{\times}10.0-40.0{\mu}m$. On the basis of the morphological characteristics and phylogenetic analyses of internal transcribed spacer rDNA, the fungus was identified as Botrytis cinerea Pers. Pathogenicity of a representative isolate was proved by artificial inoculation, fulfilling Koch's postulates. To our knowledge, this is the first report on the occurrence of B. cinerea on okra in Korea.

Among Natural monument birds, a total of 11 species and 2,209 individuals were found in Nakdong river estuary from March 2007 to February 2008 including Eurasian Oystereacher (Haematopus ostralegus; No. 326), Mandarin Duck (Aix galericulata; No.327), Tundra Swan (Cygnus columbianus; No.201-1), Whooper Swan (Cygnus cygnus; No.201-2), Black-faced Spoonbilll (Platalea minor; No.205-1), Eurasian Spoonbill (Platalea leucorodia ; No.205-2), Steller's Sea Eagle (Haliaeetus pelagicus; No.243-3), White-tailed Sea Eagle (Haliaeetus albicilla ; No.243-4), Hen Harrier (Circus cyaneus; No.323-6), Common Kestrel (Falco tinnunculus; No.323-8) and Swan Goose (Anser cygnoides; No.325-1). Among the habitats for migratory birds in Korea, the Nakdong river estuary is the only place where more than 2,000 individuals of Whooper Swan(Cygnus cygnus) spend winter. Eulsukdo, Myeongji Flat and neighboring tidal flats (Myeonggeummeori, Baikhapdeung, Doyodeung, Jangjado, etc.) are major habitats for natural monument birds such as Eurasian Spoonbill(Platalea leucorodia ), Whooper Swan(Cygnus cygnus) and Swan Goose(Anser cygnoides). A colony of aquatic plants such as Common Bulrush(Scirpus triqueter) and Common Reed(Phragmites communis) serves as a feeding and resting place for birds in the Anatidae family including ducks, swans and geese. Plans for management and conservation of the habitats and the natural monument birds in Nakdong river estuary are as follows: minimization of water contamination, construction and management of aquatic plants habitats, protection of sandbanks, security of stable habitats, and consistent monitoring.
