  • This experiment was performed to investigate the anxiolytic-like effects of cyclopeptide fraction alkaloids of Zizyphi Spinosi Semen (CFAZ), by using the experimental paradigms of anxiety, and compared with those of a known anxiolytic, diazepam. CFAZ (8.0 mg/kg, p.o.) increased the percentage of time spent on the open arms and the number of open arms entries in the elevated plus-maze test, increased the number of head dips in the hole-board test, and increased the percentage of center zone ambulatory time in the open-field box. However, CFAZ has no effect on the locomotor activity, while diazepam (2.0 mg/kg, p.o.) significantly reduced locomotor activity. CFAZ did not influence the grip force in the grip strength meter test, either. From the molecular experiments, CFAZ increased chloride influx in cultured cerebellar granule cells. In addition, $GABA_A$ receptors $\gamma$-subunit were over-expressed by CFAZ in cultured cerebellar granule cells. It is concluded that CFAZ may have anxiolytic-like effects, and these effects may be mediated by $GABA_A$ receptors.

  • The Institute of Medicine of the National Academies Food and Nutrition Board in conjunction with Health Canada recently released the sixth in a series of reports on dietary reference values for the intake of energy and macronutrients. This paper discusses the Dietary Reference Intakes (DRIs) for energy and physical activity. Several new approaches were used with the DRIs for the macronutrients. Those discussed in this paper include: $.$Estimated Energy Requirements (EER) at four levels of energy expenditure based on doubly labeled water measurements of total energy expenditure (TEE). $.$Recommendations for levels of physical activity to decrease the risk of chronic disease.

  • The main purpose of this study is to statistically analyze the difference between Korea and Japan's consumer attitudes towards e-commerce through the use of auction websites. Here are the results. First, there was a significant difference between the Korean user's attitude and the Japanese user's attitude towards Internet usage; especially, the Japanese user's attitude towards convenience showed a much higher degree than that of the Korean user. Second, Korean users preferred brand image to price, while Japanese users preferred price to brand image. Third, both the Korean users and the Japanese showed a positive relationship between Internet usage and the use of e-commerce. In contrast to the Korean user's frequent use of the bulletin board, Japanese users tended to use the bulletin board less frequently.

  • White Muscardine is the most common fungal disease of silkworm, Bombyx mori L. caused by the pathogenic fungus, Beauveria bassiana (Balsamo) Vuillemin. In the present investigation, an attempt has been made to screen locally available medicinal/ weed plants against Beauveria bassiana. Among the plant extracts (PE) tested, 5% aqueous crude extract of the bulb of Allium sativum (Garlic) has been found to be most effective against Beauveria bassiana. The radial growth of Beauveria bassiana in vitro was inhibited to the tune of 54.9% in aqueous extract and 54.4% in ethanolic extract of Allium sativum and correspondingly mycelial dry weight gave rise to 110.7 mg and 108.7 mg against 201.7 mg in control 15 days post treatment. Similarly, silkworm larvae topically inoculated with the Beauveria bassiana conidia ($1.8{\times}10^6/ml$) registered survival up to 53.0% against 0.0% in control after treatment with aqueous extract of Allium sativum. Simultaneously, as a preventive measure, silkworm larvae were put to rear in conidia contaminated seat paper instantly treated with aqueous extract of Allium sativum that also increased survival up to 61.0% against 4.6% in control. It is also observed that the plant extract is absolutely innocuous to silkworm.

  • Since 1997, JAB (The Japan Accreditation Board for Conformity Assessment) had started the activity of accreditation for the laboratory based on U.S. PL101-592: the Fastener Quality Act that was signed by President Bush on 1990. The number of accredit laboratories are 69 in Japan, 21 in Taiwan, 2 in Korea and 189 in U. S. A, as of 09/10/1998. The JAB accreditation encompasses the requirements of the ISO/IEC Guide 25, and the relevant requirements of ISO 9002. The purpose of ISO/IEC Guide 25, also had been harmonized as JIS Z 9325 'General requirements for the competence of calibration and testing laboratories 'mainly facilitates and promotes acceptance of calibration and test results between countries to avoid barriers to trade through as 'one stop testing'. The features and differences between Guide 25 and ISO 9000 will be clarify in this report.

  • 국내 농업 분야 비산먼지의 배출계수와 활동도 자료는 국내의 환경조건(풍속, 습도 등)과 농업의 특성을 반영하지 않고 미국의 인벤토리 체계를 그대로 적용해 왔다. 이 연구에서는, 활동 자료 중 하나인 시간 해상도는 풍속 및 건기일수 적용을 통해 월별 배분계수를 도출하여 지역별로 시간 해상도를 향상시켰고, 공간 해상도는 시·군·구에서 동과 리로 세분화하여 지역별로 공간 해상도를 향상시켰다. 이 연구를 통해, 지금 존재하는 농업분야의 비산먼지의 배출량, 활동도 자료의 개선에 중요한 자료로 활용될 수 있을 것으로 판단된다.

  • Objective: The purpose of the study was to investigate the effect of shoe sole deformation on the muscle activity and balance of the lower extremities when standing on one foot. Design: Crossed-control group study Methods: A total of 18 healthy adults participated in this study. 9 participants with normal shoe and 9 participants with deformed in shoe out-soles (wear shoes) were included. Muscle activity of the tibialis anterior, fibularis longus and gluteus medius during one leg standing was measured using a electromyography. A balance board was used to evaluate balance ability when standing on one leg. The balance ability when standing on one leg was measured by the sway speed and distance of the center of gravity. Results: Muscle activity of the tibialis anterior, fibularis longus and gluteus medius was no significant difference between groups (P > 0.05). Balance ability when standing on one leg was significantly different from the group wearing normal shoes in all variables related to the sway distance and sway speed of the center of gravity. Conclusions: Through this study, the wear of the outer sole of the shoe indirectly confirmed the effect on the wearer's lower extremity muscle activity and balance ability when standing on one foot. These results of this study are expected to be used as basic data for future studies on shoe wear, lower extremity muscle activity and balance ability.

  • The logical and mathematical thinking of 1- to 3-year-olds was studied by age groups at 6 month intervals; logical-mathematical thinking was examined by the two physical knowledge activities of cylinder rolling and making a slope. Results showed that in their early 1st year infants failed in both tasks. Infants in their late 2nd year showed understanding of 'rolling things' and 'non-rolling things' by comparing cylinders and cubes in the cylinder rolling activity and they showed 'spatial inference' by adjusting the position and direction of the cylinder so that the cylinder could roll properly and by adjusting the board on a block in the slope making activity. Three-year-old children rolled a cylinder and made a slope without difficulty.

  • Picrorhiza kurrooa Royle. is a well known medicinal plant among the indigenous medical practitioners of India. Present study is the first time to report the activity on the central nervous system. Preliminary study of the hot water extract showed significant depressant activity on the hole board test as evidenced from the ambulation and head dipping scores. The extract showed better activity compared to diazepam on the duration of pentobarbital induced sleeping time.
