  • Botanicals have been regarded as sustainable solution of pest control because of their nominal effect on nontarget pest, biodegradability and other environment friendly properties. However, study on impact of botanicals against beneficial insects is less. In this investigation effort has been made to study the effect of essential oils of Ocimum sanctum, Ocimum gratissimum and Ageratum conyzoides against non-mulberry silkworm Antheraea assama in terms of percent mortality, total haemocyte count (THC) and phenol oxidase (PO) enzyme activity. After application of essential oil of the plants by contact residual film technique, age dependent decrease of percent mortality was recorded. Topical treatment of oil at higher dosages ($1{\mu}lg^{-1}$ and $0.5{\mu}lg^{-1}$) caused 100% mortality of late instar larvae at 24 hour but the lowest dose ($0.25{\mu}lg^{-1}$) did not cause any mortality till 48 hour of treatment. Initial increase of total haemocyte count (THC) was recorded at early hours of treatment (0.25 hour) at all dosages (1, 0.5, $0.25{\mu}lg^{-1}$) after topical treatment. A dose dependent increase was observed in phenol oxidase enzyme activity and this might indicate ability of the essential oils to cause induction of immune response in Antheraea assama larvae.

  • As an initial step for evaluating hepatoprotective components against alcohol-induced toxicity, the effect of various fractions from Aloe vera on alcohol metabolism in rats were examined and the results were as follows: Water soluble fraction, after a single oral administration to rats, was found to cause a significant decrease in the serum ethanol concentration as well as enhancement of liver cytosolic ADH activity. On the other hand, the fractions soluble in organic solvent was found to cause an increase in the blood ethanol concentration and inhibit ADH activity. Further fractionation of the water soluble fraction by ultrafiltration system gave four subfractions corresponding to molecular weight and treatment of them in rats demonstrated that subfraction of M.W. > 30,000 exhibited the most potent enhancing activity of ethanol methabolism.

  • The objective of this research is to apply effect of the pre-mixed combustion quantity and smoke emission in diesel engine. According as air fuel ratio is increased, emission of smoke concentration is linearly reduced. As Injection timing is advanced, smoke concentration is remarkably reduced. It is considered to be the primary cause of the increase in the premixed combustible mixture during long ignition delay period with advancing injection timing. Smoke is increased with increasing engine speed, so it is considered to be the primary cause of the increase of the mass of fuel injected. Smoke is decreased according to the increase of methanol volume ratio. It is considered that the primary cause of the increase in the quantity of pre-mixed combustion.

  • Wake field effect on the electron beam from the undulator chamber in PAL-XFEL is analyzed. The wake field takeover some energy from the electron beam which will increase the energy spread of the electron beam. This will cause the degradation of the radiation power in PAL-XFEL. To decrease the effect, the surface of the undulator vacuum chamber should be fabricated with 200 nm surface roughness and 5 nm oxidation layer. In this presentation, the numerical calculation of the wake will be shown. Simulation results of the radiation generation in PAL-XFEL also will be presented.

  • The purpose of this study was to investigate efficient treatment in obesity. In order to help clinical application in obesity treatment, this study was performed to investigate the cause and treatment in obesity. The main finding of this study were as follows. 1. In the cause of oriental medicine in obesity, that were moisture(濕), phlegm(痰), gore(瘀), the productive heat(積熱), overeating, supemutrition, underaction, heredity and habitude, psychologic factor(stress) etc. 2. In the western medicine, the cause of obesity were genetic cause, endocrine disorder, hypothalamic extraodinary and secondary effect of drug. But simple obesity is the greater part. Also there were psychologicai and environmental causes. 3. Ear acupuncture of wide application were Naebunbi, Sinmun, Taejang, $ij{\check{o}}m$, $Pyej{\check{o}}m$, $Bij{\check{o}}m$ etc. 4. Body acupuncture of application were $Naej{\check{o}}ng$, $Sangg{\check{o}}h{\check{o}}$, Pungnyung, Kokchi, $Sam{\check{o}}mgyo$, $Umn{\check{o}}ngch{\check{o}}n$ etc. 5. In oriental medical treatment of obesity, Bangpungtongs ngsan(防風通聖散), Daesihotang(大柴胡湯), Seungkitang(承氣湯), Bangkihwangkitang(防己黃?湯), Richulsaryeungtang(二朮四笭湯), Taeksatang(澤瀉湯), Opieum(五皮飮), Gongyundan(控涎丹) etc were wide applicated. 6. The western medical treatment in obesity encourage the dietary cure, exercise cure and behavior adjustment than medical therapy or operation. In treatment of obesity, the dietary cure and herb-drug therapy, ear acupuncture and body acupuncture are effective. But weight maintenance after treating is more important. After all the continuous dietary cure, behavior adjusting cure and exercise cure are necessary.

  • The axial heterogeneous void distribution in a fuel channel is a relevant and important issue during nuclear reactor analysis for LWR, especially for boiling water channel-type reactors. Variation of the coolant density in fuel channel has an effect on the neutron spectrum that will in turn have an impact on the values of absolute reactivity, the void reactivity coefficient, and the fuel isotopic compositions during irradiation. This effect is referring to as the history effect in light water reactor calculations. As the void reactivity effect is positive in RBMK type reactors, the underestimation of water density heterogeneity in 3D reactor core numerical calculations could cause an uncertainty during assessment of safe operation of nuclear reactor. Thus, this issue is analysed with different cross-section libraries which were generated with WIMS8 code at different reference water densities. The libraries were applied in single fuel model of the nodal code of QUABOX-CUBBOX/HYCA. The thermohydraulic part of HYCA allowed to simulate axial water distribution along fuel assembly model and to estimate water density history effect for RBMK type fuel.

  • Customer-company (C-C) identification is the perceived fit between the identities of a consumer and an organization. If a consumer identifies with a company that places a high priority on being socially responsible, a consumer who also values social responsibility may support and patronize that business because of the link between something that is important to both them and the company. Because C-C identification may explain the success of cause-related marketing (CRM) in the fashion industry, we investigated the effect of an image resulting from CRM on ratings of brand attributes (e.g., distinctiveness, credibility, attractiveness), identification with the brand, attitude toward the brand, and customer loyalty. Participants also responded to open-ended questions reflecting their rationale for their ratings of brand attributes. Data were collected from a convenience sample of undergraduates (n = 228) enrolled at Midwestern University in the U.S. Structural equation modeling revealed that as ratings of the social responsibility of the cause-related marketing effort increased so did perceptions of the brand's distinctiveness, credibility, and attractiveness. Participants identified with a brand when they rated the brand as attractive. Participants' identification with a brand had a significant impact on attitudes toward the brand and customer loyalty (e.g., purchase intention, willingness to spread positive word-of-mouth). Content analyses of open-ended responses supported the idea that brand images stemming from CRM exert an important influence on consumer's ratings of brand attributes. Fashion marketers interested in cause-related marketing will find success with efforts that increase customer identification.

  • The focus of this study was to identify and describe environmental preconceptions held by pre-service elementary teachers about three issues : greenhouse effect, ozone layer depletion and acid rain. Two hundred and twenty nine pre-service elementary teachers participated in this study. A 36 question survey was created by one of the authors. The questions focused on the cause, effects, and interactions of three environmental issues greenhouse effect of one layer depletion and acid rain. Pre-service elementary teachers answered the questions on a Likert scale. An analysis of the survey data indicated that the majority of pre-service elementary teachers possess an array of incorrect conceptions about the causes and effects of the greenhouse effect ozone layer depletion, and acid rain. and also many pre-service elementary teachers thought that there were causal relationships among the increase in greenhouse effect, the destruction of ozone layer, and the increase of acid rain.
