放射線 照射에 衣한 人蔘貯藏에 關한 硏究 : 第2報, 감마線 照射가 人蔘粉末製品의 貯藏中 理化學的 特性에 미치는 영향 Part Ⅱ, Effect of Gamma Irradiation on the Physicochemical Properties of Ginseng Powder during the Storage

成絢淳,朴明漢,李光承,趙漢玉 한국응용생명화학회 1982 Applied Biological Chemistry (Appl Biol Chem) Vol.25 No.2

紅蔘 및 白蔘粉末製品에 對한 放射線(^(63)Co-r 線) 照射 및 照射線量과 長期貯藏이 理化學的 特性과 外觀品質 變異에 미치는 영향을 25℃에서 4個月間 저장하면서 조사하였다. 兩試料 모두에서 照射線量과 長期貯藏에 따른 變異가 거의 없었다. 理化學的 特性에서 水分, pH, 아미노態窒素, buthanol extract, 還元糖등과 사포닌분획별 패턴에도 大窒없었으나 白蔘粉末의 경우 특히 50% ethanol extract의 收率이 약간 增加되는 傾向을 보였다. 外觀品質의 경우 50% ethanol extract의 色濃度에서는 大差없었으나 粉末自體의 色度에서는 試料間에 약간 差異가 있었다. 紅蔘粉末의 경우 L値와 a値는 減少되었고 b値는 增加되어 茶褐色化 되는 傾向이었고 白蔘粉末에서는 L値가 減少되고 a値와 b値는 線量에 따라 增加되나 貯藏其間에서는 減少와 增加를 보여 濃黃色化되는 傾向이 었으나 識別可能程度의 色度變異범위는 아니었다. 全體的으로 品質의 安定性을 維持하고 있음을 보여주었다. The effect of the physiochemical properties of red and white ginseng powder after ^(60)Co-r ray irra diationduring the storage fer 4 months at 25℃ was investigated. The storage periods and the treatment of irradation at various doses on ginseng powders had no significant effects on the proximate composition and color density of ginseng extract with 50% ethanol. No changes in the contents of saponin and its HPLC patterns were found during the storage. However, a little increase was found in the yield of 50% ethanol extract and Hunter's color value of powder. But generally it was found to be stable in the physicochemical properties of red and white ginseng powder by irradiation of the intensity during the storage.

성윤경,안명주,오호석,최정혜,이영열,김인순,최일영 대한내과학회 2004 대한내과학회지 Vol.66 No.1

저자들은 만성 B형 감염을 동반한 중증 재생불량빈혈 환자에게 lamivudine을 예방적으로 투여하여 HBV의 재활성 없이 성공적으로 동종골수이식술을 시행하였기에 문헌고찰과 함께 보고하는 바이다. Reactivation of hepatitis B virus (HBV) infection has been known to be a serious complication of immunosuppressive or cytotoxic chemotherapy in HBV carriers or chronic hepatitis B patients. We report here a 25-year-old woman who has severe aplastic anemia and chronic hepatitis B underwent successful allogeneic bone marrow transplantation (BMT) with prophylactic lamivudine treatment and showed no evidence of reactivation of hepatitis B, HBV DNA elevation, or liver dysfunction. This result suggests that prophylactic administration of lamivudine to a BMT recipient of chronic hepatitis B might be a safe and promising measure to prevent fatal liver dysfunction.

항공사-여행사의 의사교환이 파트너쉽에 미치는 영향

성명순 경북과학대학 2001 金龜論叢 Vol.8 No.1

우리나라의 여행업은 관광산업 발전의 핵심적 기능을 수행하고 있다. 그러나 영세한 규모의 여행사들이 고객의 다양한 관광욕구를 체계적으로 충족시킬 마케팅전략을 수립하고 실행하기엔 역부족인 상태이다. 이러한 현실 하에서 국내여행사는 오랜 경험과 노하우 및 거대한 자원을 보유하고 있는 외국여행사들과 경쟁을 하기 위해서는 보다 빠르게 관광객의 요구 및 욕구에 대처해 나아갈 수 있는 효율적인 마케팅전략의 하나로서 파트너쉽의 관계가 요구된다. 이에 본 연구는 산업현장에서의 정확한 파트너쉽의 개념을 전략적 관점에서 새롭게 정의 하고자 한다. 또한 관광유통경로 상에서 항공사와 여행사간의 관계성인 의사교환과 파트너쉽에 대한 결속의 구성요인인 신뢰가 파트너쉽과 어떤 영향관계가 있는지 선행연구를 바탕으로 실증적으로 분석한다. 이를 통하여 항공서비스산업에서 파트너쉽의 도입과 정착이 곧 경쟁력회복의 원천임을 제시하고자 한다.

金明奎,黃光性,朴淳圭 진주산업대학교 농업기술연구소 1993 農業技術硏究所報 Vol.6 No.-

常溫 煙霧機를 개발하기 위한 기초 연구로서 常溫 煙霧機用 2流體 노즐을 설계, 제작하여 噴霧 特性에 대한 실험적 연구를 수행하여 공시 노즐의 실용성을 검토한 결과는 다음과 같다. 1. Air Compressor 압력 증가에 따른 風量의 변화는 0.4kg/㎠ 까지는 거의 비례적으로 상승한 다음 2.5kg/㎠까지는 완만하게 증가하였으나, 그 이후로는 거의 변화가 없었다. 2. 노즐, 타케트간 거리(L)에 따른 煙霧粒子의 粒徑은 L=50cm 이하에서는 附着液滴이 서로 연결해 流下하였다. L=2m에서의 粒徑은 7∼20㎛ 정도였고, 상당량의 滴下와 도나스화 현상이 나타났다. L=4m에서 粒徑의 범위는 9∼20㎛, 平均粒徑이 15㎛, 으로 비교적 均日하였고, 滴下와 도나스화 현상도 거의 완화되었다. 3. 霧化用 공기 압력에 따른 煙霧粒子 粒徑 變化는 공기 압력을 증가시키므로써 粒子의 粒徑은 감소하였으나, 2.5kg/㎠에서 15㎛, 5kg/㎠에서 10㎛정도로 2.5kg/㎠ 이상의 공기 압력에서는 압력의 증가에 따른 霧粒 粒徑 減少率은 미미하였다. 4. 藥液流量을 증가시킴에 따라 煙霧粒子의 粒徑은 완만하게 증가하였으나, 藥液流量이 5.6cc/s, L=4m일 때 粒徑은 15㎛ 정도였으며, 그 이상의 藥液流量에서는 粒徑이 급격히 증가하였다. 5. 따라서 본 供試 노즐의 air compressor 압력은 2.5kg/㎠, 藥液流量은 5.6cc/s(330ml/min), L=4m일 때 煙霧粒子의 粒徑은 15㎛으로 우수한 성능임이 입증되었으나, 附着量등에 대한 상세한 연구가 필요한 것으로 생각된다. In order to development of Korean type non-heating fog machine, twin fluid nozzles were designed and made for the Korean type non-heating fog machine.

We can precisely control photonic band gap of self-assembled thin film by seed growth of spherical SiO₂ nanoparticle. Monodispersed SiO₂ nanoparticle was fabricated through the sto˝ber process. The nanoparticle, which has narrowest particle size distribution, is used for nucleation seed. Particle size can be controlled between 50 nm and 1000 nm after seed growth. When the seed content exceeds 0.1 wt% in solution, no new particle is observed and thus narrow size distribution is obtained. Self-assembled thin film is prepared on glass substrate by evaporation with capillary extraction. There is linear relationship between the average particle size and photonic band gap according to the transmittance and reflectance measurement. Variation of photonic band gap is well matched with theoretical consideration of Bragg's diffraction law.

The purpose of this study was to investigate the relationship between skin-related variables and characteristics of clients to skin care shops. A questionnaire was administered to 300 clients, of those 89 samples were excluded due to missing values and the others, and then the data reported by 211 samples were analyzed The major findings are as follows ; 1. Of several significant predictor variables, self-esteem was the most powerful variable on irritable mood for skins. The number of clients who felt irritable for their skins was more in clients with low self-esteem than in those with highh self-esteem. 2. Of several significant predictor variables, foundation color was the most powerful variable on depressed mood. The frequency of clients who reported depressed was higher in clients using light foundations usually than in the others. 3. Of several significant predictor variables, purpose for skin care was the most powerful variable on stress experience. The number of clients who experienced stress due to their skins was more in clients for skin problems-solving than in those for prevention or relaxation. 4. Of several significant Predictor variables, foundation color was the most powerful variable on interpersonal avoidance. The frequency of clients who avoided interpersonal contact due to their skins was higher in clients using light foundations usually than in the others. 5. The frequency of clients who were satisfied with skin care was higher in clients with high liking for estheticians than in those with low liking. In summary, the number of clients who reported negative psychological reactions was more in clients with skin problems than in the others. Therefore, it is concluded that clients with skin problems require psychosocial intervention for their emotional well-being as well as skin care.

본 연구에서는 터널 화재시 임계속도에 대한 터널 경사의 영향을 파악하기 위하여 축소모형 실험을 실시하였다. Froude 상사를 사용하여 1/20로 축소된 모형터널에서 실험을 실시하였으며, 가연물질로는 에탄올 사용하였다. 정사각형 풀을 사용하였으며 발열량은 2.47~12.30 kW이다. 임계속도가 발열량의 1/4승에 비례하여 증가하였다. 터널 경사가 증가할수록 굴뚝효과로 인해 연기의 유동속도가 증가하여 임계속도가 증가하였다. In this study, reduced-scale experiments were conducted to analyze an effect of tunnel slope on critical velocity. The 1/20 scale experiments were carried out under the Froude scaling using ethanol pool fire. Square pools ranging from 2.47 to 12.30 kW were used experiments. Critical velocity varied with one-fourth power of the heat release rate. As the slope of the tunnel increases the critical velocity comes to be fast due to the increase of the chimney effect.
