  • Schizandrae Fruits has been used as a traditional Oriental medicine for treatment of many stress-induced diseases. In the present study, we investigated inhibitory activity of enzymatic hydrolysate of Schizandrae fructus (SC-EX) in growth of tested intestinal microorganism and activity of bowel inflammation related enzyme. SC-EX was added to the proteose peptone-yeast extract-fildes (PYF) media to investigation the effect on the growth of type culture of intestinal microorganism. The growth of lactic acid bacteria such as Bifidobacterium species and Lactobacillus species was accelerated by more than 3% concentration of SC-EX. But, growth of harmfulness bacteria such as E.coli, Clostridium sp. Staphylococcus sp. Streptococcus sp. was inhibited by more than 3% concentration of SC-EX. Also, SC-EX was exhibited a concentration-dependent inhibitory activity of the bowel inflammation related enzymes. The SC-EX was showed 76% and 92% inhibitory activity of 5-lipoxygenase and cyclooygenase at 5% additional concentration respectively. Our results indicated that SC-EX may possess improvement effect on the intestinal flora and Anti-inflammatory effect on the bowel.

  • The ionosphere displays variations on a wide variety of time-scales, ranging from few hours to days and up to solar cycles and even more. In this paper, we examine the ionospheric F2-layer variability in mid latitude by analyzing the foF2 and hmF2 from the Anyang ionosonde. Especially, we investigate how ionospheric semi-annual and seasonal anomalies vary with local time and solar activity. In addition to the characterization of the ionospheric semi-annual an seasonal anomalies, our study extends to the investigation of the relationship between ionospheric variability and geomagnetic activity. Finally we also discuss the coupling between ionospheric F2-layer variability and thermospheric neutral composition.

  • In the present investigation twelve indigenous medicinal plants have been screened for their antiimplantation activity in albino rats. The plant material was subjected for soxhlation successively and separately from non-polar solvents to polar solvents i.e., petroleum ether benzene and ethanol. Out of these three extracts the petroleum ether extract of seeds of Citrus medica, aerial part of Oxalis corniculata and Tinospora cardifolia have showed maximum antiimplantation activity. Ethanol extract of leaves of Cardiospermum helicacabum, roots of Echinops echinatus, leaves of Melia azedarach, seeds of Momordica charantia and bark of Terminalia bellirica have shown maximum antiimplantation activity amongst the three extracts of each plant material screened. Though all the three extracts of seeds of Annona squamosa and leaves of Zizyphus jujube screened for antiimplantation activity, no extract has showed any loss in implantation. The details of the results obtained are discussed.

  • This study investigated the environmental awareness synthetically with the drawing activity for making up for the weak points in the writing test that cannot measure emotional aspects. This study found that students have negative viewpoints on reasonable judgement for the present and future environment of the earth, while they show hope to live in better environment in their mind. Furthermore, it found that the drawing activity can be adopted as a complement for the traditional measuring method of the environmental awareness, through which this middle school students' sensibility to the environment can be shown. It also inferred that the drawing activity can be used as a way of education during school classes for environment and it can increase the sensibility to the environment in mind.

  • In this study nursing activities were examined to determine the nursing cost. A professional nursing group developed a tool for the investigation. 128 nursing activities were identified by the tool in 16 nursing care areas as referenced in the literature. Each activity was examined for four essential factors to define nursing cost ; time consumed for the care, level of professional skill, degree of independency and performer of the care. The activity was rated by a five point Likert scale. This investigation was conducted with the nursing staffing working in the 21 university hospitals in Korea and having more than four years experience especially in medical or surgical wards. The participating nursing staff were screened on the basic of the recommendation of the nursing director. The data were gathered from June 12th to August 12th, 1989. All the data were analyzed for mean, standard deviation, percent, and correlation coefficients between items. The results are summarized as follows : 1. Direct nursing care was classified into 16 large areas and 128 small activities. 2. No significant correlation was found between the study items of each activity. 3. Among 128 nursing activities, Those performed less than 50% of the time by a nurse were excluded from the nursing cost. Also excluded activities which were given less than 9 marks in all three items, time consumed, level of professional skill, and degree of independency. As a result, 83 activities in 14 nursing care areas were selected for the proposal to estimate nursing cost.

  • The purpose of this study was to investigate the characteristics of a teacher's questions in each context of musical activity by analyzing those questions in kindergarten music activity qualitatively. The participant in research was a teacher in charge of the class of children aged 7. Analysis was carried out on the data collected for 3 months through participation observance note, recording material, interview material and weekly plan. As a result, the teacher's questions were leaned upon the convergent questions to confirm the reflection of information and the understanding of function in singing and performing activity. On the other hand, the teacher's questions were leaned upon the diffusive questions for the thought of integration of information in composition activity and upon the diffusive questions for representing feeling or image with no relation to musical meaning in appreciation activity. However, the teacher's questions for control were conducted together with one of the questions, the question mentioned ahead. The tacit control question in singing and performing activity and the explicit control question in composition activity were conducted together, and in appreciation activity, the simple questions to lead the class, though not with the purpose to control attention, was conducted together.

  • In this paper, we investigate the effect of production uncertainty - especially demand fluctuation and activity time variation, to production control policies. First, we examine three famous production control policies, namely, MRP, JIT, OPT, from shop floor control perspective and analyze the difference among them. Based on these, simulation studies are performed to draw out the effects of demand fluctuation which are classified into demand lumpiness and demand irregularity, and, the effects of activity time variation which are classified into standard time variation and non-standard time variation. Experimental investigation shows that, in terms of demand fluctuations, MRP is affected by demand lumpiness, but JIT by demand irregularity. And we also see that both MRP and JIT are influenced by standard time variation with respect to activity time variations.

  • Phytochemical investigation of the EtOAc and n-BuOH fractions obtained from the crude methanol extract of the seeds of Butyrospermum parkii led to the isolation of seven compounds including 1${\beta}$,2${\alpha}$,3${\alpha}$-trihydroxyurs-12-en-28-oic acid (1${\beta}$-hydroxyeuscaphic acid) which full NMR assignment is herein reported for the first time. The above extract, fractions and some of the isolated compounds were screened for antimicrobial and antioxidant activities; 1${\beta}$-hydroxyeuscaphic acid was the more potent.
