        우리나라에서 솔껍질깍지벌레의 분포확산

        임유진,이상명,김동수,김준범,최광식,이신혜,박정규,이동운,Lim, Eu-Gene,Lee, Sang-Myeong,Kim, Dong-Soo,Kim, Joon-Bum,Lee, Shin-Hye,Choi, Kwang-Sik,Park, Chung-Gyoo,Lee, Dong-Woon 한국응용곤충학회 2012 한국응용곤충학회지 Vol.51 No.1

        솔껍질깍지벌레는 우리나라 곰솔림의 주요한 해충의 하나이다. 본 연구는 우리나라에서 솔껍질깍지벌레의 분포를 알아보기 위하여 7개도 3개 광역시, 91개 시군구, 686 읍면동의 해송림에서 2010년 밀도를 조사하였다. 5개도 2개 광역시에서 솔껍질깍지벌레가 서식하고 있었는데 시군구별로는 조사대상의 64.8%인 59개 시군구에서 서식이 확인되었다. 솔껍질깍지벌레의 분포는 남해안 전역과 동해안의 포항, 서해안의 충남 보령지역까지 분포하였다. 충북과 대전광역시 및 제주도에서는 솔껍질깍지벌레의 분포가 확인되지 않았다. 부산지역은 16곳의 모든 구에서 솔껍질깍지벌레가 분포하였고, 시군 단위에서는 전남 해남군의 솔껍질깍지벌레 평균밀도가 1.713마리/0.785 $cm^2$로 가장 높았으며 읍면동 단위에서는 해남군 송지면이 6.36마리/0.785 $cm^2$로 가장 높았다. 곰솔 가지 내의 솔껍질깍지벌레 밀도와 솔껍질깍지벌레가 서식하고 있는 빈도와는 높은 상관관계가 있었다(상관계수=0.89). The black pine bast scale, $Masucoccus$ $thunbergianae$ (Hemiptera: Margarodidae), is a serious pest of the Japanese black pine, $Pinus$ $thunbergii$, in Korea. The distribution of the black pine bast scale was examined, looking overall at 686 towns (eup), townships (myeon) or neighborhoods (dong). There were Japanese black pine ($Pinus$ $thunbergii$) forests in 91 cities, counties (gun) and borough (gu), in seven provinces and three metropolitan cities during 2010. Black pine bast scale were found in 64.8% of cities or counties or borough (59) in 7 provinces and 3 metropolitan cities, and were distributed in all South Costal regions, Pohang in East Costal region and Boryeong in West Costal region. Chungcheongbukdo, Daejeon and Jeju did not have black pine bast scale. All the gu regions in Busan had black pine bast scale, of which the area with the highest prevalence was Haenam in Jeollanamdo (1.713 crawlers/0.785 $cm^2$). Songji-myeon had the highest occurrence rate (6.36 crawlers/0.785 $cm^2$) from the towns, township and dong. The density of black pine bast scale in twigs was highly correlated with percentage of the sample with scale (Correlation coefficacy=0.89).

      • 3-deoxyglucosone에 의한 단백질의 modification

        신동범,오상환,양융 연세대학교 산업기술연구소 1990 논문집 Vol.22 No.1

        pH 7.4, 37℃의 생리적 반응조건에서 HSA, ovalbumine, BSA, lysozyme, RNase A 및 IgG와 3-deoxyglucosone을 반응시키고 단백질의 중합현상과 아미노산 잔기의 손상상태를 연구하였다. 3-deoxyglucosone은 모든 단백질을 중합시킬 수 있으나 특히 lysozyme, RNase A 및 IgG를 현저하게 중합시켰다. 또한 Arginine잔기를 크게 손상시켰다. glucose에 의한 단백질의 중합과정은 glucose가 단백질의 아미노 그룹과의 반응으로 3-deoxyglucosone을 형성시키고, 이것이 단백질의 lysine 잔기와 arginine 잔기를 공격하여 cross link를 형성시키는 것으로 추정되었다. Human serum albumin, bovine serum albumin, ovalbumin, IgG, lysozyme and ribonuclease A were reacted with 3-deoxyglucosone under physiological conditions of 37℃ and pH 7.4, and polimerization of proteins and impairments of amino acid residues were investigated. Proteins tested, especially lysozyme, IgG and ribonuclease A, were polymerized significantly, and lysine residue and arginine residue, espectially arginine residue of proteins were impaired remarkably. Experimental results strongly suggested 3-deoxyglucosone, formed from proteins-glucose reaction system, was the cross-linker responsible for the polymerization of proteins.

        The biology of aging is still emerging field and, as such, is replete with controversies and contadictions. Although the definition of aging is controversial, in the case of higher animal, it can be defined as a progressive deterioration of biological functions observed only after the organism has attained its maximum reproductive competence. Such age-dependant decline of biological functions involves complex interations among many contributing factors. Among those, oxidative damage caused by oxidative stress is the predominant cause of the age-dependant decline of biological functions. The progressive increase of oxidative stress during aging not only causes oxidative damage to cellular macromolecules, but also modulate the pattern of gene expression through functional alterations of transcription factors. Chronic oxidative stress and inflammatory reaction lead to many age-associated disease such as atherosclerosis and arthritis. Transcription factors that are directly influenced by ROS and proinflammatoy cytokines include nuclear factor kappa B(NF-kB), activator protein 1(AP-1), specificity protein 1(Sp1), peroxisome proliferator-activated receptors(PPARs) and other members of the nuclear receptor superfamily.

      • 유전자조작 농산물의 개발현황과 그 안전성 평가

        신동범 제주대학교 환경연구소 1998 환경연구논문집 : 제주대 Vol.6 No.-

        In recent years, the safety of foods and food ingredients from genetically modified plant varieties has been widely discussed. Genetical modification technique to transfer genetic information from one species to another has been possible for about two decades. The ability to transform, or insert new DNA into the plant cell, exists now for most crops, including maize, wheat, soybean, cotton, and rice. Early products of this technology include plants with enhanced insect and disease resistance, and improved herbicide tolerance. Future goals are to increase higher yield, improve nutritional and processing characteristics, and produce specialty oils, carbohydrates, and proteins. Some examples of genetically modified products that have been commercialized are FLAVR SAVR™ tomato, Bollgard^㉿ cotton, Round-Up Ready㉿ soybean, Maximizer™ and NatureGard™ corn, Laurical㉿ Canola oil, and Feedom IF" squash. The international agencies. OECD and WHO, and USDA. FDA and EPA in United States issued a policy statement on foods derived from new plants varieties each other. The document from FDA discussed criteria that should be considered by plant breeders and food manufacturers in assessing the safety of foods derived from new plant varieties before they enter the marketplace. Even though genetically modified plants and their foods are now evaluated safe enough by scientific experiments. the present scientific knowledges won't the truth forever. The ultimate judges of new products of biokhnology will be consumers. They will be more confident in the safety of foods derived from plants deveolped by new technology if scientist and developers share information on safety testmg.

      • 생리적조건에서 L-Ascorbic acid의 분해물질

        申東範 제주대학교 1993 논문집 Vol.37 No.-

        . The degradation products of L-ascorbic acid was examined by incubating it alone and in the presence of α-N-formal-L-Lysine(NFL) at pH 7.4(0.2M phosphate buffer) in the presence of oxygen, metal ion chelator, and in both the presence and absence of sodium cyanoborohydride. Among the large number of degradation products produced, threonic, oxalic, glyceric and glyoxylic acids, as well as threose were all identified by GLC-MS. Decarboxylation is also a feature of the degradation, with approximately 30% of the ascorbic acid undergoing degradation via this pathway. In the presence of NFL and cyanoborohydride ??-N-caboxymethyl-L-lysine(CML) was detected as a reaction product as well. Using GLC-MS as the detection method and ascorbic acid-1-?? as the reactant, only glyoxylic acid and CML were found to contain a ?? Label, indicating that, of the compounds identified above, only these latter two contain C-1 of ascorbic acid.

      • 미생물 포괄고정화를 위한 고정화재의 비교검토

        신동범,윤창훈,강경수 제주대학교 환경연구소 1997 환경연구논문집 : 제주대 Vol.5 No.-

        We conducted the experiments to find out the appropriate gelling materials for the treatment of waste water by immobilizing microorganisms inside the gels. The gelling materials known to immobilize microorganisms or cells in them are polyacrylamide, polyvinylalcohol, sodium alginate, κ-carrageenan and chitosan. The gel strengths were determined by the breaking points of the pellet using a rheometer with reaction time. The polyacrylamide gels were retained their solidities and activities excellently compared with the other pellets of polyvinylalcohol, sodium alginate and chitosan with reaction time. It is considered that, in the other hand, the polyacrylamide gels are toxic to the single microorganisms and cells by free radicals during the formation of gels. We used activated sludge for the mmobilization, so it didn't matter the toxicity caused by free radicals. The profiles of waste water treatment by all the immobilized pellets using in this study were showed nearly similar patterns, but gel strength of all the gels except polyacrylamide pellets were getting weak and weak as reaction time goes by. It was concluded that the polyacrylamide gels are excellent for immobilization of activated sludge for waste water treatment, but in the case of immobilization of single microorganisms or cells, natural polysaccharides of sodium alginate, κ -carrageenan or chitosan are thought to be suitable, and it must be developed the techniques for elevating gel strength of nautral polysaccharides.

        내열성 Chitinase 생산균주의 분리 및 효소생산 특성

        홍범식,윤호근,신동훈,조홍연 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.5

        자연계 고온환경으로부터 내열성 chitinase 우수하고 반응산물로 N-acetyl-D-glucosamine 이량체(GlcNAc)_2를 생산하는 균주를 분리 선별하고 Bacillus licheniformis KFB-C14로 동정하였다. 선별균주의 효소생산 특성은 탄소원으로서 효소기질인 colloidal chitin이 첨가될 때만이 생합성이 유도되었으며 유도제의 첨가시기에 의해 효소생산이 크게 영향을 받았다. 각종 무기, 유기태 질소원 중 yeast extract가 활성과 비활성을 각각 약 2배 증가시켰으며 높은 친화도를 나타내었다. 균의 최대생육과 효소의 최대생산온도는 55℃이었다. 본 균주의 내열성 chitinase 생산에 미치는 최적배양조건은 1.2% colloidal chitin, 0.15% K_2HPO_4, 0.05% KH_2PO_4 0.01% MgSO_4·7H_2O, 0.1% yeast extract, pH 6.5의 배지를 55℃, 150rpm에서 40시간 회전진탕배양 하였을 때로 3.89 units/ml의 효소활성과 7.4 units/mg의 비활성을 나타내었다. A strain capable of producing thermostable chitinase suitable for chitooligosaccharide production was isolated from high temperature environment and identified as Bacillus licheniformis. The chitinase from Bacillus licheniformis KFB-C14 was only induced by addition of colloidal chitin into the basal medium as carbon source, showing the decrease of the chitinase production by supplemental addition of other carbon sources into the medium containing 1.0% colloidal chitin. Among organic and inorganic nitrogen sources, yeast extract was the most effective for the increase of total activity and specific activity, and had high affinity for the enzyme production. The optimum temperature of cell growth and thermostable chitinase production was 55℃. The optimum culture medium was composed of 1.2% colloidal chitin, 0.15% K_2HPO_4, 0.05% KH_2PO_4 0.01% MgSO_4·7H_2O, 0.1% yeast extract (pH 6.5). Bacillus licheniformis KFB-C14 produced the thermostable chitinase of 3.89 units per culture fluid and 7.4 units per mg protein under rotary shaking at 150 rpm for 40 hr.

      • 外國籍企業의 會計報告制度에 관한 硏究

        朴範鎬,申東洙,蔡奎學,李均,金喆中 弘益大學校 1983 弘大論叢 Vol.15 No.1

        In Accounting, a new problematic field has been recognized with the development and changes in industrialized society. An accounting system of a multinational corporation emerged from different accounting environments between one country and another. This environment can be summarized as follows; (1) Accounting measurement that affect financial position and management performance of an accounting entity are made by foreign currency, not by domestic currency or reporting currency of a parent company. (2) The exchange rate is not fixed, but fluctuating. (3) In case the foreign business activity is conducted by the foreign entity, separated from the parent company at home, the enterprise activity is done under entirely different circumstances. Such environmental changes in their fundamental effects upon accounting differentiate the meaning of a accounting measurement. Accounting reports by heterogeneous measurements has diminished in informative worth of accounting measurements because there are not secured comparability. Thus, as far as possible, accounting reports should be integrated to one financial statements, identically combined from different home and foreign accounting measurements. The reason that problems of accounting reports of multinational corporation has emerged into a new problematic field is to develop the theory and method to identify different accounting measurements. This paper is to suggest more reasonable directions of reporting system of accounting for multinational corporation, and to explore theoretical foundations of aaccounting report by clarifying the basic problems and characteristics of accounting standards of some countries and their reporting practices. For this purpose, this paper focuses on the discussion of the main subject as follows; (1) The sources and characters of the problems of accounting reports that emerged by the nature and characteristic activities of multinational corporation. (2) Analysis of some country's current accounting standards and reporting practices of multinational corporation. (3) More reasonable model building for accounting report with a view of external and internal management reports.
