  • The enhancing effect of excreted cell factors on the production of somatic embryos from suspension cultures of Daucus carota was studied as a function of factors including molecular size, harvesting time, injection period, and concentration of the extracellular compounds. The production of late-stage embryos was increased up to 1, 500 embryos/ml compared with control cultures when high molecular size and extracellular factors, extracted from newly established embryo culture at early stationary phase, were added at the starting time. The stimulating effect on the production of somatic embryos can be attributed to the presence of high molecular size(> 10 kDa) compounds.

  • Bovine follicular oocytes were matured in two different conditions, TCM 199+10% FBS with or without hormones (0.01 unit/ml ovine follicle stimulating hormone, 0.01 unit/ml ovine luteinizing hormone and 1$\mu\textrm{g}$/ml $\beta$-estradiol). There was no significant difference in maturation and fertilization rates of the oocytes between two groups. The result indicates that hormonal treatment does not have beneficial effect on in vitro maturation and fertilization of follicular oocytes. IVF-derived cone-cell bovine embryos were injected with foreign DNA (CChcLf) by microinjection method and then co-cultrued with bovine oviductal epithelial cells. Developmental rate of microinjected embryos to blastocyst stage (21%) was similar to that of non-injected embryos(29%). This result represents that microinjected bovine embryos produced in vitro have a potential of development to normal blastocysts.

  • Studies were carried out to clarify the effect of ginsenoside-Rbl -Rbr and acid hydrolyzatps of ginsenoside-Rbl, -Rb2 (HRbl, HRbf) on lipolysis and lipogenesis induced by epinephrine, glucagon, ACTH (adrenocorticotrophic hormone), TSH (thyroid-stimulating hormone) and insulin in rat adipose tissilr. HRbl , HRb2 slightly inhibited lipolysis induced by epinephine. glucagon and TSH. ACTH-induced lipolysis in fat tissue slices was significantly inhibited by ginsenoside -Rbl, -Rb2, HRbl and HRb2, particulary HRb2. None of ginsenoside-Rbl, -Rb2, HRbl and HRb2 accelerated insulin-stimulated lipogenesis in fat calls. Among ginseng products, extract powder (freeze dried), extract powder (spray dried), red ginseng powder inhibited ACTH-induced lipolysis in adipose tissue slices, but red ginseng extract not affect them.

  • This study purposed to examine how the window display of flower shops affects consumers' buying desire, and for this purpose, we surveyed flower buying customers' interest in window display according to their gender, age, and occupation. The survey was conducted using a questionnaire with flower shop customers in Seoul, Daegu, and Gyeongju. Interest in window display was over 1.5 times higher in women than in men. Among criteria for choosing a flower shop, window display was more important than other factors. With regard to experience of being stopped by unique window display, many of the respondents replied that they had such an experience, and the frequency was higher among women than among men. Among different types of window display, theme-type window display was most effective m stimulating customers' curiosity and buying desire. According to occupation, housewives showed particularly high interest in window display. The results of this study show that the window display of flower shops has a significant effect on consumers' buying desire.

  • In this study, a survey research was conducted on government employees in Busan Metropolitan City to identify the influence of cyber education factors (learning factor, learner factor, and learning system factor) on the preference for government employee cyber education offered by the government always learning system. Analyzed results, recognition of learning factor, learner factor, and always learning system were shown to have significant influence on the preference for cyber education, but no indication of influence by always learning support. This study intends to assist stimulating voluntary participation in cyber education and active commitment in learning activities through improving learning effect and fortifying convenient informatization education, with regard to activation of cyber education and improved preference for cyber education.

  • Whole body vibration is a new type of exercise that induces the response and adaptation of the neuromuscular system by stimulating tendons or muscles through vibration of various frequencies and muscle strength on the footrest. Therefore, in this study, we tried to find out the effect of health promotion and physical fitness promotion on agility, flexibility, and quick reaction ability in the state of general paralysis. Body vibration exercise was additionally applied to the entrance examination practical program for students preparing for the physical education entrance exam.

  • Madhuca indica has been used ethnomedically in Indian folks. In the present study we have investigated anti-inflammatory, anti-ulcer and hypoglycaemic effect of ethanolic extract (EE) and crude alkaloid extract of Madhuca indica seed cake on albino rats. The study showed that the EE had a significant, dose dependent anti-edematogenic, anti-ulcerogenic and hypoglycaemic activity, whereas the crude alkaloid extract exhibited a significant only. Both the extracts possess dose dependent inhibitory activity on carrageenan-induced edema, inhibiting prostaglandins or mediators involved in prostaglandin synthesis, the second phase of inflammation. The EE was significantly effective in protecting pylorus-ligation-induced gastric ulcers at a higher dose level. The active principle of EE seems to be a selective inhibitor of the COX II (prostaglandin synthesis) without important effect on COX I since, EE exhibited both anti-edematogenic and anti-ulcerogenic effect. The EE was effective in reducing the plasma glucose level in normal albino rats in a dose dependent manner, producing hypoglycaemic effect by stimulating the release of insulin from the ${\beta}-cells$ and/or increasing the uptake of glucose from the plasma.

  • In this paper, a sensory effect authoring tool is introduced to effectively generate sensory effect metadata for sensible media. Sensible media manifests sensory effects in the media to real world by stimulating sensory organs of human. It is emerging as a new media to enhance the user's immersion towards media. For the successful deployment of the sensible media industry, an effective authoring tool is required to provide easy authoring of sensory effect metadata. The result of the authoring tool design and development based on MPEG-V(ISO/IEC 23005-3) International Standard is presented in this paper.
