The purpose of this study is to make profits and enhance national competitiveness through the globalization of Korean food. For this purpose, this study analyzed the certificate of qualification for Korean cooking technicians in the field of technical cooking. The results of presenting the perception, motivation for acquisition, and improvement measures of the Korean cooking certificate are as follows. First, as for the perception, if Korean cooking technicians acquire the certificate, they are acknowledged to acquire the qualifications and basic technology as licensed cooks in Korean food; however, they cannot practically execute cooking affairs. They cannot receive additional marks in time of employment. Getting the special education in cooking schools is helpful to acquiring the certificate. Second, the motivation for acquisition results from its advantage over other types of business, and a hope for running Korean food restaurants. Third, the improvement measures cover changing examination contents to be utilized in practical affairs, improving cooking methods, fair evaluation, and considering excessive technicians not to depreciate the value of the certificate.

The distribution of standing wreaths has reached about 7.1 million per year and the size of the standing wreath market is estimated to be at least 700 billion won. Among them, 20 to 30 percent are estimated to be reused, resulting in damage to flowerfarms' sales of 110 to 160 billion won per year. Due to the unique characteristics of conventional 3-tier standing wreaths in terms of transportation and installation, companies that lack design expertise have monopolized local distribution markets, and the issue of illegally using standing wreaths has been raised. These issues have highlighted the need for developing new designs and establishing a distribution system to expand the consumption of flowers. This study was carried out to identify consumers' perception of reused standing wreaths and the current systems introduced to prevent the distribution of reused standing wreaths such as the real-name standing wreath production system, the authenticity certificate system, and new standing wreaths. The results of a consumer survey showed that consumers' perception of reused standing wreaths has been high and that reused standing wreaths need to be actively regulated to establish fair trade order and protect consumers' rights. Although the effectiveness of the real-name system, the authenticity certificate system, and new standing wreaths was found to be insufficient, the introduction of these systems was essential and necessary for continuous promotion through broadcasting media.

Mideoduck drips were mixed with amino acids (Met, Tau, Gly, Ala, Thr, Cys), thiamine and sugars (Glucose, Ribose) for flavor modification and evaluation using the Maillard reaction. To mask the seafood flavor, onions, spring onions, garlic, ginger, citric orange and green tea were mixed with Mideoduck drips at $160^{\circ}C$ for 2.5 hr in a stainless still reaction bomb. The glucose/thiamine model reaction system was estimated to be lower than the ribose/thiamine model system, and an extreme case is the ribose/Met model system. Mixed system of glucose, ribose and taurine containing sulfur compounds showed fair results. Among the Mideoduck drips mixed with sugars and amino groups, only thiamine model systems were estimated to be normal. The flavor composition of Mideoduck drips/sugars model system, and long chain fatty acids were composed of 31.32~62.71% total flavor content. The 1,2-benzenedicarboxylic acid dibutylester contents made up more than 20% of the model system in groups A, B and C. From the model system in this study, drip/glucose, drip/ribose, drip/glucose/citric orange, and drip/glucose/glycine/cystine groups showed most intense good flavor.

This study was investigated the ovarian response following superovulation treatment at different day of diestrus. The criterion for the presence or absence of a dominant follicle based on their morphological examination. Dominant follicle was puntured 48 hrs before the oneset of superovulation treatment by ultrasonography guided aspiration needle. Superovulation was induced by subcutaneous administration of FSH twice a day for 4 day in a decreasing regimen. There was no significant different between presence of dominont follicle and progesterone concentration/diameter of corpus luteum in HanWoo. Number of corpus luteum of donor after superovulation treatment was not significantly different in FSH administration at day 9, 11 and day 13 of estrus($14.5{\pm}4.5$, $15.5{\pm}5.6$ and $11.0{\pm}5.5$, respectively). But, the diameter of CL was significantly correlate(R2 = 0.757) with progesterone levels on day of superovulatory induction. After 7 days of artificial insemination, the embryos at 7 days were collected by uterine flushing after dominant follicle aspiration and superovulation treatment, and evaluated their quality by morphological criteria. Fifty five embryos with excellent, good and fair grade were transferred into 24 recipient cows. Seventeen offsprings, 1 of triplet, 4 of twins and 6 of singlet, were yield from 10 recipient cow. In conclusion, the present study showed that 1) dominant follicle can be determined by ultrasonography with rectal palpation by morphological evaluations, 2) superovulation response after follicular aspiration was not differ at day 9, 11 and 13 of estrus, 3) dominant follicle did not affect to progesterone concentration and diameter of CL, and 4) diameter of CL was significantly correlate to the level of progesterone concentrations in HanWoo.

The purpose of this study is to provide essential data necessary to assess ecological flow requirements by understanding habitat conditions for fish species through monitoring an ecological environment in the Korea stream (Dal Stream) and building related database. On-site surveys were conducted for identifying ecological and habitat conditions at the four monitoring sites. Fish sampling was carried out at the selected four sites (St.) during the period ranging from September, 2008 to September, 2009. At the four sampling sites, we measured water surface elevation, depth and velocity at the cross-sections. Optimal Ecological Flowrates (OEFs) were estimated using the Habitat Suitability Index (HSI) established for four fish species Zacco koreanus (St.1), Pungtungia herzi (St.2), Coreoleuciscus splendidus (St.3), and Zacco platypus (St.4) selected as icon species using the Physical HABitat SIMulation system (PHABSIM). Eighteen species (56.3%) including Odontobutis interrupta, Coreoperca herzi and C. splendidus were found endemic out of the 32 species in eight families sampled during this study period. The endangered species was collected Acheilognathus signifier, Pseudopungtungia tenuicorpa and Gobiobotia macrocephala, and this relative abundance was 9.4%. The most frequently found one was Z. platypus (31.3%) followed by C. splendidus (17.6%) and Z. koreanus (15.7%). The estimated IBI values ranged from 27.3 to 34.3 with average being 30.3 out of 50, rendering the site ecologically poor to fair health conditions. For C. splendidus (St.3), the dominant fish species in the stream, the favored habitat conditions were estimated to be 0.3-0.5 m for water depth, 0.4-0.7 m/s for flow velocity and sand-cobbles for substrate size, respectively. An OEFs of 8.5 m³/s was recommended for the representative fish species at the St.3.

This research was conducted to make suggestions for the promotion of research activities in the Life Sciences field, and we evaluated the research funding trend and the present status of research funding offered by KOSEF in this field. Researchers in this field have received more research funding from the group-based programme than from the individual-based programme. Also, they have received less money (per project) than did researchers in other Science and Technology fields. The portion of research funds given to the Medical Sciences fields has markedly increased year by year, whereas the portion of funding given to the Agricultural Sciences and Biological Sciences fields has decreased annually. To encourage research activities in the Life Sciences field in Korea, the following actions and systems are required: 1) formulation of a mid-and a long-term research master plan, 2) development of a database on man power in related fields, 3) activation of top-down research topics, and associated increase of individual research grants, 4) development of special national programs for basic researches in Life Sciences, 5) organization of a committee for policy and planning within related societies, and 6) system development for fair evaluation of the results of research activities.

Most severe problem in production of potted kalanchoe during summer season is retardation of growth caused by high temperature. The aim of this experiment was aimed to investigate the effects of natural products such as algin-oligosacchride and glucosamine oligosaccharide, plant growth promoting rhizovacteria such as Pseudomonas sp. B and Pseudomonas sp. D2, and AG-solution on the growth of potted kalanchoe under the different root zone temperature in the greenhouse. Growth characteristics in terms of plant height, leaf length, leaf width, leaf area, leaf weight, fresh weight of shoot and root and root length were recorded under three root zone temperatures (25$^{\circ}C$, 30$^{\circ}C$, 35$^{\circ}C$). In 25$^{\circ}C$, the mixed treatment of Pseudomonas sp. B and glucosamine oligosaccharide resulted in the best growth in terms of plant height, leaf area and root weight. In 3-$^{\circ}C$, glucosamine oligosaccharide treatment gave fair result in plant height and leaf weight, but the mixed treatemtn of Pseudomonas sp. D2 and algin-oligosaccharide showed better growth on leaf area and root weight. In 35$^{\circ}C$, the mixed treatment of Pseudomonas sp. B and glucosamine oligosaccharide could greatly improve the plant height, leaf area, leaf weight and root weight. These results demonstrated that the mixed treatment of natural products and microorganisms could overcome the detrimental effects caused by high temeprature in the production of kalanchoe.

Books in libraries can be highly refined information. Google invests digitization of books in libraries. But the digitization of books that has a variety of interests, coupled with several problems, including class action, in addition the many critical discussions are underway. Korea pushed the national digitization projects, what are libraries' digitizing their collection of many books. Of course, in publishing and digitization of the target is limited to books published ahead of Google. However, the Library Act was amended for the reposition of online materials, but only in the ways that Google's case is different. Library Act permits collection of online resources through the library to allow, the legislation can be considered as leading act. However, online data is publicly not available through the Internet, so this service hae limited means and range unlike Google. This paper, the digitization of books in the library due to copyright, examines the legal issues looking for the desirable solution. Physical library's main role had been kept the book, but we use the book in terms of policies needed to consider. To overcome these limitations of Copyright Act, this paper researches the relation of Google Book Search in our Copyright Act, and considers introduction as the fair use doctrine and the digital repository system.
