The three ayurvedic medicinal plants, Withania somnifera, Emblica officinalis, and Bacopa monnieri, were extracted by high-pressure static extraction using the Zippertex® technology. The extracts were mixed to reach quantifiable amounts of active compounds identified by high-pressure liquid chromatography-mass spectrometry (HPLC-MS) analysis. The mixture of extracts was incubated with resting cells of the fungus Beauveria bassiana ATCC 7159. The fermentation promoted the fluidization of the starting dense mixture, while HPLC monitoring evidenced the disappearance of glucogallin from E. officinalis extract and the concomitant increase in gallic acid content. Topical exposure of the chick embryo chorioallantoic membrane (CAM) to the nonfermented extract led to the extensive necrosis and destruction of the treated membrane. However, the fermented extract was shown to be free of any toxicity. Furthermore, compared with the untreated CAM, the fermented sample reduced CAM vascularization, suggesting its antiangiogenic potency. The innocuity of the fermented extract was demonstrated using the in vivo LD50 test, the morphological examination of internal organs of treated rats, as well as the evaluation of blood biomarkers of liver damage (aspartate aminotransferase and alanine aminotransferase). The fermented extract was developed as a nutraceutical antiangiogenic treatment of age-related macular degeneration and commercialized in an oral form named Ethnodyne-Visio™.

Medical institutions are important to develop and maintain enduring relationship with medical service conswners. So, this research aims to find out the effect of medical service conswners perception of relational benefits on relationship quality and behavioral intention. On the basis of the literature review, the research model is established. This research has been done through the survey utilizing medical service consumers in Gangwondo, and the effective 368 questionnaires are tested for the research model. The main findings are as follows. First, among 5 key dimensions of relational benefits, psychological, customization, economic, and information benefits except social benefits have significant effects on relationship satisfaction. Also, medical institutions type and medical service consumers type as moderating variables are included concurrently, and the significant differences are found in other 4 benefits except relationship between social benefits and relationship satisfaction. Second, relationship satisfaction relates positively to relationship commitment and behavioral intention. But the normative commitment, one of 3 key dimensions of relationship commitment, has no significant effects on recommendation to others. Third, the revisit intention has significant effect on recommendation to others. Finally, the findings reveal that the overall goodness fit index of the model is comparatively good and model set in this research is significant. At the end of the research, managerial implications, limitations and future research directions are suggested.

홍삼 추출물이 반치사량정도의 방사선(5Gy)에 조사된 생쥐조직 및 이들 조직에서의 효소활성에 미치는 영향을 관찰하기 위하여 ICR계 생쥐를 대상으로, 생리적 식염수군을 대조구군으로 하여, 홍삼 추출물 투여군과 방사선만을 조사한군 및 홍삼 추출물 투여후 방사선 조사군 등 4군으로 나누어 1일, 4일, 9일, 17일 및 30일 등 5회에 걸쳐 생체의 조직중 비장 및 고환에서의 중량 변화 및 GOT와 GPT의 활성을 측정하여 결과를 얻었다. 비장의 중량변화는 1일째 및 4일째 최소치를 보이다가 이후 증가추세를 보였으며, 고환의 중량 변화는 17일 이후 급격한 감소로 30일에도 증가하지 못했다. GOT의 활성도 변화는 비장에서는 초기에 현저히 증가했으며 이후 회복하는 경향이었다. 방사선 조사군들에서는 홍삼추출물 투여군이 방사선만을 조사한 군보다 빠르게 회복하는 경향이었으며 고환에서의 GOT활성은 매우 불안정하였다. GPT 활성도 변화는 비장, 고환에서 모두 초기에 증가하다가 점차 회복하는 경향이었으며 홍삼 추출물 투여후 방사선 조사군이 방사선만을 조사한군보다 빠르게 회복하는 경향이었다. 이러한 결과로 볼 때 홍삼 추출물은 방사선 조사에 의하여 기인된 비장 및 고환의 GOT와 GPT활성도 증가에 방호효과가 있다고 생각된다. This study was prepared to observe the change of tissues weight, glutamate oxaloacetate transminase(GOT) and glutamate pyruvate transminase(GPT) activities in the spleen and testis treated with red ginseng extract injection in the gamma ray irradiated mice. Groups were divided into control, red ginseng extract injection, irradiation after saline injection and irradiation after red ginseng extract injection. The spleen and testis weights were decreased at 17th day irradiation after saline injection and irradiation after red ginseng extract injection. The GOT activity showed earlier recovery at irradiation after red ginseng extract injection group than irradiation after saline injection group in the spleen. The GPT activity showed earlier recovery at irradiation after red ginseng extract injection group than irradiation after saline injection group in the spleen and testis. The above result suggest that red ginseng extract have the recovery effect on the change GOT and GPT activity after radiation injury in the spleen and testis of mice.

The polymerization of Acrylamide initiated by MnO4-H2C2O4 redox pair has been studied in aqueous media at 35±0.2℃ in nitrogen armosphere. The rate of polymerization is independent of activator concentration (2×10-3 to 4.5×10-3 mole/1) expect at very high (above 6.3×10-3 mole/1) concentration. The initial rate of polymerization has been found to be proportional to nearly 1.17 power of low catalyst concentration (2.3×10-4 to 6.25×10-4 mole/1) and nearly the first power of low monomer concentration (1.47×10-3 to 3.3×10-3 mole/1). The overall energy of activation has been found to be 10.99kcal/mole within the temperature range 30-50℃. The effects of various additives have been studied. Organic solvents and salts depress the initial rate but small amounts of manganous salts(MnSO4, MnCl2) increase the initial rate to a considerable extent. A complexing agent(NaF) and anionic and cationic surfactants show marked influence on the rate of polymerization. The intrinsic viscosity in aqueous acrylamide solution at 30±0.1℃ was 1.01 and the molecular weight of the polyacrylamide was 63,900.

A two-dimensional warranty policy is characterized by a region in a two-dimensional plane with one axis representing time or age and the other representing item usage, such as the age and mileage of an automobile. This paper proposes a new two-attributes warranty policy that the failed product is free-replaced by producer in the replacement and minimally free-repaired by producer in the repair regions. We obtain expressions for the expected warranty costs under some assumptions about usage and failure and illustrate through numerical examples.

OSS systems that are represented by the carrier preselection and number portability services con no longer be operated by themselves in their own domains since the freedom and various changes in electronic commerce require the interconnections between the heterogeneous OSS systems. However, since the cost of direct internonnections of OSS systems is so enormous we must consider the use of OSS gateways to interconnect heterogeneous OSS systems. In this research, we analyze the security weakness for interconnecting OSS systems throught gateways and suggest the security requirements for the OSS gateway.
