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.

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.

This study was conducted to discover the maost desirable height for shoe heels. An analysis of human kinematics and gaits according to different kinds of shoe heel heights was carried out. Walking, which is related to the locomotor and nervous systems, is different from running. It has some unique characteristics such as the double-supporing phase and the pelvis-centered smooth connections with tension and flexion which can make it possible to walk comfortably. The specific goals of this study are as follows: 1. To analyze the variables of gait cycles with respect to shoe heel height. 2. To analyze the variables of linear kinematics with respect to shoe heel height. 3. To analyze the variables of anguiar kinematics with respect to shoe heel height. 4. To discover the ideal heel height to promote a comfortable walking style. Limits of this study: 1. The processes of BSP and Yeadon-kwon were used. 2. The shoe heel heights investigated were 1. 0 cm(ie: bare foot) 2. 3cm 3. 5cm 4. 7cm 3. The equipment used in this experiment comprised of : a Panasonic VCR: VCR analyzer and analysis program: a Kwon "3D Mothion Anaysis" package. 4. The subjects of this experiment were 3 female collage students who are not used to wearing high heeled shoes: all are aerobics instuctors. with an exellent sense of equilibrium. The model of the human body is defined as a rigid body system connected by 19 jonts(for the purpose of this experiment the nose included as an imaginative joint to give precise direction). In order to reduce any displacement which may occur during didgitization. Iandmarkers were attatched to each of the 19 body segments of each subject. The subject were then asked to walk firstly in bare feet and then wearing shoes with a 3cm, 5cm, and then 7cm heel. A video camera zoom lens was used to record the subjects' walking patterns(RTD-LTO-LTD-RTO-RTD) for one complete gait cycle and the direction of the subject was defined wsing X and Y axes. After the digitization and interpolation of all frames the linear and angular variables which are necessary for the study were calculated. The results of this study are as follows: 1. The time taken to complete one gait cycle increases or decreases by a negligable amount as heel heights vary. It appears that the higher the heel is, the longer the length of each stride will be and the greater the horizontal displacement at the center of the body. 2. When a higher heel is worn vetical displacement is increased during the initial phaze of each gait cycle however when a lower heel is worn. vertical displacement is increased in the final phaze of the gait cycle. 3. The average horizontal speed of each phase increases, regardless of the height of the heel. 4. The vertical speed decreases. regardless of heel height in any gait cycle, the speed decreases with each consecutive phaze eg: in a cycle consisting of :RTD-LTO-LTD-RTO-RTD. the initial phaze from RTD to LTO will the fastest movement in the cycle. the speed will decrease with each concecutive phaze in the cycle. The second phaze of the gait (LTO to LTD) will be slower than the first, and the the final phaze (LTD to RTO to RTD) being the slowest in the cycle. (Overall. the rate of decrease in speed in the last the last phaze of any gait cycle is always slower than the decrease of the first two phazes. therefore we can put the last two phazes together to make one final phaze (LTD-RTO-RTD) as the decrease in speed is so small.) 5. For each motion variable, the difference in tension and flextion of lower body joints is not apparent, using any heel height. The tension and flextion in the shank and thigh is negligable with a 5cm or 7cm heel. The tension and flextion is the most apparent when using a 3cm heel. 6. The walking speed changes little according to heel height alterations. The common outcome is that there is a slow increase in speed after the LTO phase, so that when supporting body weight on the right foot, it is very hard to move on to a new 'centered' body weight position. No problem appears when using a 3cm-heel. however when walking bare foot. there is more pressure on L5 and on S1 than with a 3cm-heel. this is because walking is a forward-motion and the center of the body is left behind when walking bare foot. In conclusion, it is the 3cm-heeled shoe that is the most suitable height to promote a comfortable forward walking motion.

Ryew, C-C and Kim, I-S. Kinematic Analysis of Badminton Smashing Between the Skilled and the Unskilled. Korean Journal of Sport Biomechanics, Vol. 13, No. 2, pp. 139-160. The purpose of this study was to suggest the guideline for scientific and quantitative skill acquisition methods of badminton smashing so that the novice could learn the motions of badminton smashing efficiently. The subject participated consisted of total 6 middle school students of the skilled(3) and the unskilled(3). The cinematographical experimental & Analysis equipments used in the study were composed of two Model D-5100 Video Cameras, a control point, a synchronization timer and Kwon3d motion analysis system. The conclusions obtained were as follows; 1. It was necessary for the unskilled to learn the smashing impact phase in situation of max. Velocity of COG in order to minimize the timing loss phase. 2. Particularly, The power from segments of Power Zone must participate in utilization in sequence of order of trunk-upper arm-forearm-hand-racket segment in both the skilled and the unskilled. 3. Therefore It was necessary for the unskilled to do smashing practice for cumulated sum of absolute & relative velocity transfer into shuttle cock after adjusting anterior-posterior tilting angle and max timing, in sequence of segment recruited.
