  • Developing new substance for immunosuppressor or immunomodulator from natural products is extremely important in the present biomedicine. In this paper, we focused our efforts on the mitogenicity and immunochemical properties of the two lectins (LCC-I, LCC-II) obtained from marine animal Lunella coronata coreensis. Immunochemical techniques were employed to elucidate the structural and/or functional similarities between the LCC lectins. Molecular weight of the LCC lectins, LCC-I and LCC-II were estimated to be around 60 KD and 66-70 KD, respectively. LCC lectins were mitogens for murine splenic lymphocytes, and the optimum mitogenic doses were 31.25 $\mu\textrm{g}$/ml and 3.91 $\mu\textrm{g}$/ml, respectively. LCC-II lectin was a good mitogen toward human peripheral lymphocytes at a concentration about 31.25 $\mu\textrm{g}$/ml.

  • The purpose of this study was to investigate the relationships among thinking styles and creative personality in early childhood teachers. The subjects of this study were 167 teachers who work in kindergarten in Busan. Data were gathered with Thinking Style Inventory and Creative Personality Scale. ANOVA, Pearson's correlations and multiple regression analysis were used for data analysis. The results of this study were as follows: First, there was no difference in creative personality by teachers' background. But there were significant differences in thinking styles by teachers' background. Second, there were significant correlations between thinking styles and creative personality. Third, legislative, liberal, conservative, anarchic thinking styles were significant contributors to predict creative personality.

  • Salted anchovy, generally favored in Europe, is one of the traditional fermented fish products in southern European countries and raw anchovy are aged in 20∼30% NaCl solution for 6 months (Ishida et al., 1994). They are then steeped in oil in glass jar or can, and marketed. The salt-fermented fish sauce, such as anchovy sauce and shrimp sauce are tropical fermented seafood from fish in Korea. (omitted)

  • To maintain the freshness of produce, because of stand away between produced and consumer, we need refrigeration system that can supply to consumer at cold chain as soon as gathering. General refrigeration system consist of refrigeration chamber or low temperature store. But the vacuum technology can rapidly refrigeration without refrigerator. This precool system possible to get low precooled temperature, suitable for the fishes, the meat, the vegetables, the fruit etc. Especially get advantage that quality maintain through rapid refrigeration of ferment directly generate heat. Vacuum precool system's principle is that water saturated temperature reduce according to pressure is get to vacuum area, so product temperature reduce as water evaporation at product. In vacuum suction, unit, on early experiment period run the rotary type vacuum pump at purpose pressure, then maintain pressure by water-diven ejector. As the results, cabbage took about 60 minutes to reach from $23.2^{\circ}C$ to $4.5^{\circ}C$at 5mgHg abs.

  • Squid Sikhae is a traditional salt-fermented food in Korea. We evaluated the standardization of optimal processing conditions for desirable quality-controlled squid Sikhae using analyses of physiochemical properties, microbiological species, and organoleptic tests. The optimal fermentation temperature, sun-dried sea salt concentration, and fermentation period for manufacturing squid Sikhae products of the aceeptable quality were $10^{\circ}C$, 4%, and 6 days. In addition, optimal concentrations of the additional ingredients of red pepper powder and crushed garlic for acceptable quality squid Sikhae were both 6%.

  • The marine sponge Petrosia sp. is known for various bioactive compounds including the recently reported polyacetylenic alcohols. In our continuous survey of bioactive compounds from the Petrosia sp. collected from Korean waters, a cyclopentanepentol which rarely occurs in natural products has been isolated. It was found to inhibit DNA replication at the initiation step.

  • The aim of this study is to utilize the algae extracts with functionalities such as antioxidant and antimicrobial properties for preparing lip balm. Functional properties of extracts from Dictyota coriacea and Ulva pertusa were evaluated in terms of DPPH radical scavenging activity and antimicrobial activity. Lip balms contained the algae extracts were tested its efficacy by measuring the moisture retention of lip skin after applying human subjects. According to the results of skin moisture retention measurement, lip balm was effective to increase the moisture retention of lip skin. It is considered that the utilization of colorants extracted from algae which are verified of antioxidant effect and antimicrobial activity is valuable and useful in developing the cosmetic products.

  • With the draining of land resources, and rising new economic and resources expansionism, finding a new and yet to be developed ${\ulcorner}treasure{\lrcorner}$ is often a fierce and competitive challenge among many nations. This is especially true for Korea confronted with its urgent needs to find new resources and strategy to maintain the current pace of societal demand and economic development in this often impatient and rapidly progressing world. The ocean world in the South Pacific provides potentials to quench both orders with promises of new ${\ulcorner}treasure{\lrcorner}$ of living and ecosystem resources such as new fisheries and new bioactive products as well as providing alternative aesthetic, recreational resources and critical informations on various societal problems such as extreme weather conditions and early wining of the consequences resulting from global environmental changes.

  • The structure of premixed turbulent flames in constant volume vessel was investigated by using a laser tomography. The flame structure was visualized by passing a laser sheet with 0.2mm thick and 2 cm wide through the turbulent flames to obtain their 2-D images. From the obtained images islands of reactants as well as of products were found at least in the 2-D images when the turbu-lence intensity was above 0.4m/s. Moreover in order to obtain the characteristic flamelet thickness the light intensities of them were digitized and processed into three colors incorporating two appro-priate threshold values in the image analysis. As the result the averaged value of charactertistic flamelet thickness was found to be about two times compared to laminar one.
