Objective: In this study, the dental health care knowledge, dental health behaviors and dental health status of elementary school students were compared and analyzed in the cases of their schools having dental health care center or not one. Methods: The target groups were 167 students of A school (experimental group) where pit-and-fissure sealants, fluoride mouthrinsing, and fluoride gel application were carried out with all grades of students by school dental health care center and 158 students of B school (control group) where fluoride mouthrinsing, for all grades students and pit-and-fissure sealants for the first grade students are carried out but have no the school dental health care center. Results: This study was carried out through the answer sheets and recordings of dental inspection. The findings of this study are as follows: 1. The dental health care knowledge was compared and the results showed that on average 14.2$\pm$2.1 in experimental group and 14.0$\pm$1.9 in the control group were no significantly different (p>0.05). 2. The dental health behaviors were compared and the results showed that the experimental group was significantly different(p<0.05) in terms of the number of times of dental brushing a day, the method of tooth brushing, the time of tooth brushing, the experience of tooth brushing with fluorine, the kinds of snacks and tooth brushing in school after lunch. But there was no significant difference(p>0.05) in the time of tooth brushing and the tooth brushing after eating snacks. 3. The DMF rate was compared and the results showed the significantly difference between the average experimental group and 53.8$\pm$5.0 in the control group(p<0.05). 4. The DMFT index was compared and the results showed the significantly difference between the average 0.6$\pm$2 in the experimental group and 1.4$\pm$1.6 in the control group(p<0.05). 5. The DMFI rate was compared and the results showed the significantly difference between the average 4.2$\pm$8.3 in the experimental group and 9.5$\pm$11.0 in the control group. (p<0.05). 6. The DT rate were compared and the results showed the significantly difference between the average 10.2$\pm$29.5 in the experimental group and 32.4$\pm$44.0 in the control group(p<0.05). 7. The FT rate were compared and the results showed the significantly difference between the average 88.5$\pm$31.0 in the experimental group and 67.5$\pm$44.0 in the control group(p<0.05). Conclusions: Based on the results, above there was no significant difference in dental health care knowledge between both the experimental and the control group. But we discovered that the experimental group is better than the other one in dental health care behaviors and dental health status. Therefore, we could conclude that the school dental health care center efficiently carried out the dental care and treatment.

The purpose of this study was to investigate the various expressions with materials in fashion illustration using CAD comparing with hand work. The design motive for this study is to be selected from Bell Epoque era which was the revolutionary period in fashion illustration. The results of this study were as follows: 1. By using CAD, water color was well expressed to repeat brushing for the clarity, darkness, and brightness. It was more effective to use CAD in layering or duplicating complex and intricate patterns because the base color gets to be concealed under the repeated oil pastel. Acryl, like oil pastel, was easily absorbed in canvas, so it is effective to repeat brushing for expressing pure color. It was inconvenient to use wax crayon for controlling the moderate opacity because wax crayon absorbed water color dye stuffs, so crayon line was concealed when repetitions were being done. 2. The advantage of using CAD was convenience for getting rid of troublesome process and inefficient works. Also, CAD had a good tool like oil pastel in the use of coloring work by using pure color. By using CAD, various expressions on materials and texture of surface can be achieved effectively. Also, it is very strong substitute for time-saving, convenience, economic aspects from providing simple instrument, and production in the state of various kinds of paper and canvas as a method of visualization. Therefore, fashion illustration using CAD provides effective way of producing works, and gives promising vision in the future.

Introduction : Inadequate oral health control is a major risk of oral diseases. Regular home-based care is essential to maintain good oral hygiene. In particular, mouthrinses can support conventional tooth brushing in reducing accumulation of oral plaque. Effect : Antimicrobial mouthrinses are used as part of daily oral care to reduce plaque and gingivitis. Mouthrinses contains fluoride could help remineralization of enamel and dentin. The most common molecules contained in mouthrinses are chlorhexidine, essential oils, cetyl pyridinium chloride, triclosan, hyaluronic acid. Currently, chlorhexidine is the most efficacious compound, with both antiplaque and antibacterial activities. Similar results are reported for essential oils and cetyl pyridinium chloride, although with a somewhat reduced efficacy. Considering the adverse effects of chlorhexidine and its time-related characteristics, this molecule may best be indicated for acute/short term use, while essential oils and cetyl pyridinium chloride may be appropriate for long-term, maintenance treatment. Conclusion and suggestion : Antimicrobial mouthrinses are safe and effective, and when used in conjunction with brushing and flossing, they are an important method of reducing plaque and gingivitis. To improve compliance, dental health care professionals should adapt oral health care recommendations to fit patients' specific needs.

Many ancient and historical artifacts were made by copper and its alloys. In the case of outdoor exposure artifacts, the surface could be suffered from corrosion and tarnish by the reaction with its environment. In order to preserve the artifacts, surface treatment would be needed and BTA coating has been usually applied to tin-bronze. This paper dealt with the evaluation of the properties of BTA coated film using a linear polarization method and AC impedance measurement. On the base of corrosion rate and film resistance for the specimen formed by coating process, optimum coating conditions are as follows; 3 cycles brushing or 3 cycles spraying coatings for natural dried process and 1 cycle brushing coating or 5 cycles spraying coating for hot-air dried process.

연구배경 : 기관 삽관을 한 환자에서 정확한 폐렴의 진단과 원인균을 파악하는 것이 쉽지 않다. 경기관 흡인물(endotracheal aspirate) 배양검사는 간편하지만, 객담채취시 오염의 기회가 많고, 부적절한 객담채취의 기회가 높아서 그 원인균을 알아내는데는 어려움이 많다. 따라서 본 연구에서는 폐렴 진단 방법의 일환으로 좀 더 간편하고 비침습적인 방법인 blind PSB를 시행하여 진단의 유용성과 치료 및 예후에 미치는 영향을 알아보고자 하였다. 방 법 : 기관 삽관을 한 환자중에서 감염성 폐령이 의심되었던 51명의 환자를 대상으로 blind PSB(protected specimen brushing)를 시행하였고, 경기관 흡인물(endotracheal aspirate) 배양 및 혈액 배양검사를 통한 진단 결과와 비교하였다. 대상환자에서 기관 삽관 튜브를 통하여 폐렴이 생긴 폐구역에 해당되는 기관지에 접근하여 PSB 카테터로 기관지내의 화농성 분비물을 채취하여 15분 이내에 정량적 배양검사를 의뢰하여 $10^3/ml$ 이상의 colony forming units를 보일 때 양성으로 판정하였다. 결 과 : 51명의 환자 중 병원내 감염 폐렴은 27명(52.9%)이었고, 이 중에서 VAP가 19명(37.3%)이었고, 지역사회 감염 폐렴은 15명(29.4%)이었다. 비 폐렴성 폐 침윤으로 확인된 9명(17.6%)의 환자 중 울혈성 심부전이 5명(98%), 폐결핵이 3명(5.9%), 폐출혈이 1명(2.0%) 이었다. 원인균 규명을 위한 배양검사의 민감도와 특이도는 객담에서 각각 83.3%(35/42), 77.8%(7/9), 혈액에서 각각 14.3%(6/42), 100%(9/9)였고, blind PSB에서는 각각 548%(23142), 88.9%(8/9)였다. 유사한 민감도와 특이도를 고려하면, blind PSB는 객담배양검사에 비하여 우월하다고 할 수 있다. 초기 항생제 치료는 blind PSB 배양결과에 따라서 항생제를 교체하였는데, 항생제를 교체한 환자군의 생존율은 교체하지 않았던 환자군의 생존율과 통계적으로 유의한 차이가 없었다. 결 론 : Blind PSB는 기관 삽관된 환자에서 폐렴이 의심되는 경우 비감염성 폐침윤과의 감별에 도움을 주고 폐렴의 원인균을 간편하고 빠르게 확인하는데 유용하다. 또한 경기관 흡인물 배양검사에 비해 신뢰도는 낮지 않으면서 정량적 배양이 가능하여 불필요한 항균제의 사용을 감소시킬 수 있을 것으로 사료되며, 기관지 내시경검사를 할 수 없는 환자에서도 이용이 가능하다. 또한 기관지 내시경이 필요없어 검사비용에 비한 효과면에서 유용하고 안전한 검사이다.

The following results were obtained after data adjustment and analysis of a study consisting of self-writing, of oral check-ups and questionnaires of 356 students of the O middle school in Suwon in June of 2000. The purpose of this study was to discover the effects of the dental health types of middle school students on dental caries and to understand the specific teeth of dental health types due to educational experience. Based on such data, we want to develop a desirable educational program for middle school dental heath. 1. The DMFT index was higher in females (0.75+4.39) than males(4.99+3.67), so there was a significant difference(p=0.000) 2. The DMFT index increased from the ages of 12 (4.69+3.90). 13 (5.69+3.67), 14 (6.18+4.39) and 15(6.98+4.08) and were significantly different (p=0.011). 3. There was no difference in the DMFT index regarding the method of brushing, educational experience for dental health, oral hygiene index and plaque index in dental health types. Yet, the more snack-eating increased the higher the DMFT index increased; thus, there was found a significant difference (p=0.0006). The more fluoride use increased, the lower the DMFT index; thus, there was a significant difference (p=0.048). As for the self-awareness index of dental health, the ones who answered positively had a DMFT index of 2.14+ 1.83 and those who answered negatively had a DMFT index of 7.00+3.94; thus, there was a significant difference (p=0.000). 4. For those who had had educational experience in dental health, a rolling method was used in brushing, and the frequency of fluoride use was high; the self-awareness index of dental health was high as well.
