        BB 랫드 및 streptozotocin이 투여된 랫드에서 vitamin E와 insulin 병합 투여 영향 II. 인지질의 지방산 조성에 미치는 영향

        김순태,허린수,Kim, Soon-tae,Huh, Rhin-sou 대한수의학회 1995 大韓獸醫學會誌 Vol.35 No.4

        The present study was investigated fatty acid composition of the phospholipid in the RBC membrane, liver and microsomal fraction after vitamin E and/or insulin treatment to evaluate the effect of vitamin E on the oxidative stress in STZ-treated rat and BB rat. Results obtained through the experiments were summarized as follows; 1. Effect of vitamin E and/or insulin treatment in STZ-treated rat 1) In the insulin treated group and the combination treated groups of vitamin E with insulin, body weights were increased compared to STZ-treated rat(STZ control group). Especially it was more significantly increased in the combination treated group of high dose vitamin E with insulin. 2) The composition of fatty acids of the phospholipid in RBC membrane, liver and microsomal fractions was shown a decreased C16:1, C18:1, C20:4 and an increased C16:0, C18:0, C18:2 in STZ control group compared to normal control group. In RBC membrane, liver and microsomal fractions after vitamin E with insulin treatment in STZ-treated rat, effect on the composition of fatty acids of the phospholipid was shown the result of a decreased C16:0, C18:0, C18:2 and an increased C16:1, C18:1, C20:4. 3) Hemolysis rate of the RBC to $H_2O_2$ was increased in the STZ control group and it was decreased below the hemolysis level of normal control group by vitamin E treatment. 2. Effect of vitamin E and/or insulin treatment in BB rat 4) Only in microsomal fraction, fatty acid composition was different between insulin treatment group and vitamin E with insulin treatment group. It was increased C16:0 and C18:1, and decreased C18:0 and C18:2 in vitamin E with insulin treatment group: But C20:4 was not different in two groups. These results suggest that the combination treatment of vitamin E and insulin could prevent the oxidative change of fatty acids in P-lipid of the RBC membrane, liver and microsomal fraction in STZ-treated rats and BB rats.

      • 소상공인특성과 정부지원정책 요인이 사업전략 및 경영성과에 미치는 영향

        김순태(Kim Soon Tae),유창(Liu chang) 한국산학기술학회 2014 한국산학기술학회 학술대회 Vol.2014 No.2

        소상공인들은 대부분 생계형에 의한 가족경영이 주를 이루고 있어, 경기에 민감하여 폐업율이 높다고 하지만 업종전환 및 재창업의 관점에서 보면 제조업보다 생명력이 높다는 평가다. 기존연구는 소상공인의 특성(경영, 자원, 환경)들이 경영전략 및 경영성과에 미치는 영향을 연구했으나, 본 연구에서는 매년 정부에서 자금, 교육, 컨설팅 등을 지원하지만, 지원결과가 사업전략 및 경영성과에 제대로 영향을 주고 있는지, 지원정책에 문제가 없는지 등 상관관계를 분석하여 소상공인의 경쟁력 제고를 위한 ‘소상공인 SPEC 이론’을 정책적 함의로 도출하는 계기가 되었다.

        Sodium chloride와 sodium carbonate를 첨가한 yellow alkaline noodle sheet의 물리적 특성

        김순태(Soon Tae Kim),장학길(Hak-Gil Chang),박영서(Young-Seo Park) 韓國食品科學會 2007 한국식품과학회지 Vol.39 No.1

        밀가루에 소금을 0 2 및 4%를 첨가하였을 경우 Mixograph의 peak time은 밀가루의 종류에 관계없이 소금 첨가량이 증가함에 따라서 증가함을 알 수 있었으나 박력분의 경우에는 유의적인 차이를 나타내지는 않았다. Peak height와 width at peak도 소금 첨가량이 증가함에 따라 증가하는 경향을 나타내었으나 강력분과 중력분에서는 유의적인 차이를 나타내지 않았다. Width at 8 min의 경우에는 모든 밀가루에서 소금 첨가량이 증가함에 따라 증가하는 경향을 나타내었다. Sodium carbonate를 0 0.5 1.0 및 1.5의 농도로 밀가루에 첨가하여 Mixograph 특성을 관찰한 결과 밀가루의 종류에 관계없이 0.5% 첨가 시 peak time이 거의 2배정도 증가하였다가 그 보다 높은 농도에서는 다시 감소된 반면 peak height는 sodium carbonate 첨가량이 증가함에 따라서 감소하는 경향을 보였다. Mixograph peak time과 단백질 함량 및 침전가와는 유의적인 상관이 없었으나 peak height width at peak 및 width at 8min과는 모두 정의 상관관계를 보여 주었다. 반죽의 초기호화온도 최고점도 최소점도 최종점도는 밀가루의 종류에 관계없이 소금의 첨가량이 증가함에 따라 증가하는 경향을 나타내었으며 최고점도 최소점도 및 최종점도는 모든 밀가루에서 sodium carbonate 첨가량이 증가함에 따라서 유의적으로 증가하는 경향을 보였다. 초기호화온도와 보수율 및 알칼리수 흡수율과는 정의 상관이 있었으나 보수율과 최고점도 최소점도 및 최종점도와는 모두 부의 상관관계를 보여 주었다. The peak time peak height width at peak and the width at 8 min of Mixograph increased as the amount of sodium chloride in yellow alkaline noodle sheet was increased. The peak time of the Mixograph duration increased almost twice when 0.5% sodium carbonate was added to yellow alkaline noodle sheet but decreased when the amount of sodium carbonate was above 0.5%. The peak height decreased as the amount of sodium carbonate increased. Protein content and sedimentation values showed positive correlations with the Mixograph peak height width at peak and width at 8min. The pasting temperature peak viscosity minimum viscosity and final viscosity increased as the amount of sodium chloride in yellow alkaline noodle sheets was increased for all wheat flours. The peak viscosity minimum viscosity and final viscosity also increased as the amount of sodium carbonate increased. The pasting temperature showed a positive correlation with the water retention capacity and the alkaline water retention capacity.

        As all other intensively farmed domestic species, most mortality in ostriches is closely to rearing conditions. While ostriches is also highly sensitive to stress, species-specific infectious disease play only a minor role. But investigation of ostrich`s disease is not performed almost in Korea. The study was performed to investigate the titers of antibody for Newcastle disease(ND), Infectious bronchitis(IB), Egg drop syndrome ``76(EDS), Avian influenza(AI), salmonellosis, Mycoplasma gallisepticum infection(MG), Mycoplasma synoviae infection(MS), Infectious bursal disease(IBD), Brucellosis, Toxoplasmosis, Japanese encephalitis(JE), Porcine parvovirus infection, Encephalomyocarditis and Porcine reproductive respiratory syndrome (PRRS). The results obtained in the 62 ostrich sera slaughtered in Gyeongbuk province were summarized as follows: The average of antibody positive rates to ND, IB, EDS, AI(H9N1), JE, Porcine parvovirus infection and Encephalomyocarditis by HI test were 75.8%, 100%, 0%, 0%, 51.6%, 50% and 56.5% respectively. The antibody positive rates to salmonellosis, MG, MS by plate agglutination test were 12.9%, 25.8%, and 0% respectively. Antibodies to disease agent such as IBD and AI by agar gel precipitation(AGP) test, Brucellosis by tube agglutination, toxoplasmosis by latex agglutination test and PRRS by IFA were all negative.

        F53 슈퍼 듀플렉스 스테인리스강의 미세조직과 국부 부식 거동

        김순태 ( Soon Tae Kim ),이인성 ( In Sung Lee ),공경호 ( Kyeong Ho Kong ),박용수 ( Yong Soo Park ),이종훈 ( Jong Hoon Lee ),양원존 ( Won Jon Yang ) 대한금속재료학회(구 대한금속학회) 2015 대한금속·재료학회지 Vol.53 No.7

        The localized corrosion behavior associated with microstructure of F53 super duplex stainless steel (SDSS) was investigated using a potentiodynamic polarization test, a critical crevice temperature test, an electron probe micro-analyzer analysis, and scanning electron microscopy-energy dispersive spectroscopy analyses. Crevice corrosion was initiated at the α/γ phase boundaries, MOx inclusions (where M is Cr, Mn, Al, Fe, or Ti), as well as Cr and Mo depleted areas adjacent to the σ-phases precipitated in the F53 SDSS alloy. This alloy had been annealed at 1050 ℃ followed by improper water-cooling, and the corrosion was propagated into the α-phases because the pitting resistance equivalent number (PREN) of the α-phase was smaller than that of the γ-phase. As cooling rate increased, the variation of the α-phases decreased, and the content of the Cr and Mo rich σ-phases decreased, thereby increasing the corrosion resistance.

        HDDM과 BFM을 이용한 NOx와 VOC 배출량에 대한 오존민감도계수 산정 및 결과 비교: 2007년 6월 수도권 사례

        김순태 ( Soon Tae Kim ) 한국환경과학회 2011 한국환경과학회지 Vol.20 No.11

        The accuracy of ozone sensitivity coefficients estimated with HDDM (High-order Decoupled Direct Method) can vary depending on the NOx (Nitrogen Oxides) and VOC (Volatile Organic Compound) conditions. In order to evaluate the applicability of HDDM over the Seoul Metropolitan Area (SMA) during a high ozone episode in 2007 June, we compare BFM (Brute Force Method) and HDDM in terms of the 1st-order ozone sensitivity coefficient to explain ozone change in response to changes in NOx and VOC emissions, and the 2nd-order ozone sensitivity coefficient to represent nonlinear response of ozone to the emission changes. BFM and HDDM estimate comparable ozone sensitivity coefficients, exhibiting similar spatial and temporal variations over the SMAduring the episode. NME (Normalized Mean Error) between BFM and HDDM for the episode average 1st- and 2nd-order ozone sensitivity coefficients to NOx and VOC emissions are less than 3% and 9%, respectively. For the daily comparison, NME for the 1st- and 2nd-order ozone sensitivity coefficients are less than 4% (R2> 0.96) and 15% (R2> 0.90), respectively. Under the emission conditions used in this study, two methods show negative episode average 1st-order ozone sensitivity coefficient to NOx emissions over the core SMA. The 2nd-order ozone sensitivity coefficient to NOx emissions leads ozone to respond muchnonlinear to the reduction in NOx emissions over Seoul. Nonlinear ozone response to reduction in VOC emissions is mitigated due to the 2nd-order ozone sensitivity coefficientwhich is much smaller than the 1st-order ozone sensitivity coefficient to the emissions in the magnitude.

        오스테나이트 스테인리스 주강의 미세 조직 및 고온 산화 특성에 미치는 합금원소의 영향

        김순태 ( Soon Tae Kim ),이인성 ( In Sung Lee ),전순혁 ( Soon Hyeok Jeon ),이정석 ( Jung Suk Lee ),고영상 ( Young Sang Ko ),김종명 ( Jong Myoung Kim ) 한국주조공학회 2010 한국주조공학회지 Vol.30 No.5

        To elucidate the effects of alloying elements on the characteristics of microstructure and high temperature oxidation of cast austenitic stainless steel, a thermodynamic calculation, a cyclic oxidation test, a X-ray diffraction, a scanning electron microscopy-back scattered electron, a electron probe microanalysis were conducted. The thermodynamic calculation for the effect of vanadium (V) addition on the formation of various precipitates leads to a decrease of chromium (Cr)-rich M23C6 carbides due to the formation of M (C, N) carbo-nitrides containing V and / or niobium (Nb). The V added alloy increased the resistance to high temperature oxidation due to a decrease of Cr-depleted zone deteriorating the oxidation resistance and due to the V-enriched oxide layer formed in inner oxide layer blocking the outward transport of cations.

        This study was conducted to determine vaccination programs for the control of Newcastle Disease (ND) in chickens and investigate protective effect against Newcastle disease virus(NDV) after live ND vaccination. Maternal HI antibody titer level of chickens according to day(age) 1, 7, 14, 21, 28 and 35 were decreased gradually as 7.10±0.74, 6.57±1.27, 3.71±1.25, 2.20±1.03, 1.20±1.23 and 0.50±0.71. As a result of HI test and ELISA, both chickens vaccinated with VG/GA strain live vaccine at 1-day-old and chickens not vaccinated do not have antibody titer for protection against NDV at 14-day-old. Except for LaSota strain vaccine, in case of vaccination with VG/GA spray and VG/GA, B1 and LaSota strain drinking water at 14-day-old, the protective effect was 100% in chickens inoculated NDV(10(7.2) EID50/50㎕, eye drop) at 21-day-old, but not 10~50% at 28-day-old. These data suggest that live NDV vaccination should be given at 10-day-old and 20-25 day-old for protect against NDV at periodic outbreaks of ND caused by velogenic viscerotropic NDV in the environment of a farm.
