The effects of saponin and histamine solution on the division of Saccharomyces cerevisiae were compared with the effects of ginseng on the division. 1. $10^{-2},\;10^{-3}%$ saponines were inhibitory on the division but $10^{-5}%$ saponin increased slightly the division, however its increasing rate was much less than that of ginseng. 2. 0.5% histamine was inhibitory on the division but $10^{-2}%$ histamine increased the division, however its increasing rate was higher than that of saponin and lower than that of ginseng. 3. Although some doses of saponin and histamine were inhibitory on the division, the increasing dose of saponin or histamine on the division could be recognized as shown in the case of the optimal dose of ginseng.

In an effort to increase the operational efficiency of highways, South Korea has been increasing its design speed recently. However, the use of higher design speed will also increase construction costs. Moreover, increasing the design speed is expected to have an impact on safety. Hence, there is a strong need to demonstrate that the benefits outweigh the cost of having a higher design speed. This study surveyed a sample of design engineers to determine their awareness of the consequences of increasing design speed and their assessment of the right design speed for an actual rural arterial. In addition to the survey, a case study of three recently upgraded highways was conducted to determine the changes in traffic volumes, speeds, travel times, and safety.

An attempt was made to study wetting behavior of various low temperature molten frist on ceramic substrates including high alumina silicon carbide and porous fired clay plates by Sessile-drop method. The cosine values of contact angles between substrates and molten frist were linear as a function of temperature unless chemical reactions between substrate and molten frit occured. Addition of BaO to frit composition indicated that cosine of values of contact angles were gradually increased with increasing temperature but in the frist contained $Li_2O$ consine values were abruptly increased with increasing temperature after reached a certain temperature. The contact angle increased with increasing roughness of the substrate surface in case of alumina substrate plate.

$RuO_2$-based high frequency thick-film resistor paste was printed at the speed of 10, 100, 300 mm/sec on the AlN substrate, and then sintered at between 750 and $900^{\circ}C$. The sintered thick films were characterized in terms of printing and sintering conditions. With increasing printing speed, the thickness and roughness of sintered film increased. The resistance of the thick film resistor was reduced by increasing the printing speed from 10 to 100 mm/sec, but did not significantly change at 300 mm/sec speed. With increasing sintering temperature, the surface roughness and thickness of sintered resistor film decreased. The reduction rate was large in case of fast printed resistor. The resistance of the resistor increased up to $800^{\circ}C$ with sintering temperature, but again decreased at the higher sintering temperature.

This study was investigated the effect of subzero treatment in austempered ductile cast iron. Retained austenite transformed to martensite by subzero treatment and strain. With decreasing subzero treatment temperature and increasing strain, retained austenite transformed more to martensite and transformed 30% above by subzero treatment at $-196^{\circ}C$. With decreasing subzero treatment temperature, the value of strength and ratio of increasing of strength, hardness and ratio of increasing of hardness increased but the value of elongation and ratio of decreasing of elongation decreased. With decreasing subzero treatment temperature, impact value and ratio of decreasing of impact value decreased. In case of subzero treatment at $-196^{\circ}C$, hardness value increased about 18% and impact value decreased above 20%. We could find that in subzero treated specimens had a little of effect on the tensile properties but had very much effect on the hardness and value of the impact.

Objectives : Recently, the number of cancer patients who use complementary and alternative medicine (CAM), including oriental medicine, are increasing. Also, evidence for efficacy and safety of cancer CAM is reported continuously. This study was designed to evaluate the quality of the published papers for clinical studies about oriental medical cancer treatment in Korea. Methods : We searched for clinical research papers on the websites of the Korean oriental medical society and subsidiary academies, Korean traditional knowledge portal. Koreanstudies information service system (KISS), etc. We used the reference words 'cancer', 'malignant tumor', 'leukemia', 'lymphoma', 'multiple myeloma', 'melanoma', etc, We then chose studies that had been presented between 1991 and 2008 and analyzed them by publication year, design, cancer type, intervention, subject and journal. Results : There were 86 clinical research papers that were published between 1991 and 2008. The number of clinical studies has increased in a time-dependent manner. Case reports and case series studies account for 78% of total clinical research. Studies of lung cancer account for 17%. Studies of cancer-related symptoms of cancer patients account for 38%. Studies of Hang-Am-Dan account for 33%. Studies published in the journal of the Korean Society of Oriental Internal Medicine account for 35%. Conclusion : The clinical research papers about oriental medicine are increasing over time, but most of the studies are retrospective case reports or case series. Well-designed and prospective clinical trials would be recommended to provide more reliable evidence.

Purpose: During guided bone regeneration procedures for the augmentation of deficient alveolar ridge, primary closure of flap is necessary. For primary flap closure, flap is repositioned coronally and the zone of attached keratinized mucosa may decreased. The need for attached keratinized mucosa around dental implants is still controversial, but sufficient peri-implant attached keratinized mucosa would be beneficial for functional and esthetic aspects. This case report presents three cases that demonstrated free gingival graft for increasing the zone of peri-implant attached keratinized mucosa which was decreased after guided bone regeneration. Materials and Methods: In first case, maxillary incisors were extracted and guided bone regeneration was performed simultaneously. Because the membrane was exposed at 3 weeks after operation, the membrane was removed and free gingival graft was performed for primary flap closure. Free gingival graft was performed again at implant placement for the increase of attached keratinized mucosa. In second case, guided bone regeneration was performed on lower right first molar area, and implant was placed with free gingival graft. In third case, lower right molar area showed insufficient attached keratinized mucosa after implant placement with guided bone regeneration. When abutments were connected, free gingival graft with apically positioned flap was performed. Result: In these three cases, the zone of attached keratinized mucosa around dental implants was decreased after guided bone regeneration. And the increase of peri-implant attached keratinized mucosa could be obtained effectively by free gingival graft. Conclusion: Free gingival graft could be a effective treatment method increasing the zone of attached keratinized mucosa which was decreased after guided bone regeneration procedures.
