This study was intended to prepare the basic data required for the development of oral products for the patient with diabetes by analyzing the relation between diabetes and oral health and the actual condition of oral care from the senior citizens diagnosed with diabetes out of the senior citizens over 65. In this study, 8 senior citizens who visited the senior welfare center in D city, were organized into the group of 4 senior citizens and the interview approximately for 40 minutes per group was conducted. In the results of this study, 5 core topics of 'Diabetes and Oral Health", 'Oral Discomfort', 'Oral Care Method', 'Visit to Dentist' and 'Demand for Oral Care' were drawn. For the relation between diabetes and the oral health, the most of research subjects answered that they heard about it for the first time, They answered that for the oral health care, they brushed the teeth using toothpaste 3 ~ 4 times a day and for the visit to dentist, they visited the dentist only when they had oral problem. For what is necessary for oral care, they answered that they wish that the oral care education customized for patient with diabetes and diverse oral care products such as toothpaste, etc. would be developed. Considering the results of this study, the development of oral care management program and the development of oral products in future are deemed to be necessary.

This study aimed to suggest the optimum number of rinsing by researching changes in optical density and pH in accordance with the number of rinsing after toothbrushing, and then verifying the amount of residual toothpaste in mouth. Total 14 university students who had healthy body with no difficulties in daily life were selected from the students of K university in Daegu as the research subjects. The research subjects rinsed their mouths with 40ml of water from zero time to 12 times after toothbrushing. After collecting each rinsing water, the optical density and pH were measured. In the results of measuring the optical density value of each rinsing water, the rinsing water of six-seven times or more after toothbrushing showed the constant value of optical density, which was statistically significant(p<0.05). There were no differences in accordance with the amount of toothpaste such as 1g, 1.5g, and 2g. Based on such results of this study, it would be necessary to provide the education of the use of dentifrice, and also to have diverse researches on the effects of residual dentifrice in mouth on the oral cavity.

The authors have studied the 8 weeks clinical examination On 32 patients of age 20s for experimental group and 34 patients of the same ages for control group, in order to find out the effect of plaque removal effect and gingival effect by use of the dentifrice contained with the Artemisiae Capillaris extract(dimethylesculetin) and NaCl. The obtained results are as followings: 1. Plaque removal effect is better at the experimental group than at the control group on 2 and 8 weeks(p<0.05). 2. There are not significantly differences on the calculus index and stain index between the experimental group and control group, during the 8 weeks experiment(p>0.05). 3. At the 8 weeks experiment, it revealed the less average scores on the PMA index for experimental group, than that of the control group(p<0.05).

Purpose: The study aims to evaluate satisfaction of toothpaste adding natural materials extracted from Zanthoxylum schinifolium and various herbs (Pine, Lemongrass, Spearmint). Methods: We performed the first survey to collect basic data for the development of natural herbal toothpaste. Participants were the general public in Jeonju and Iksan of Jeollabuk-do, and a total of 273 questionnaires were analyzed for the study. By adding anthoxylum schinifolium and herbal extracts (Pine, Lemongrass, Spearmint) to the toothpaste, four kinds of natural herbal toothpaste prototypes were manufactured. The second survey was conducted to assess the satisfaction one week after using the natural herbal toothpaste prototypes. Results: Satisfaction with current toothpaste was 3.52. The most important criterion of toothpaste was the prevention of tooth caries. 55.3% participants obtained toothpaste information through advertising. The survey indicated the most worrisome ingredient of toothpaste was surfactant, showing 55.3%. The overall satisfaction of natural herbal toothpaste was 3.99; among the four natural herbal toothpaste, toothpaste 2 (Zanthoxylum schinifolium, Lemongrass) showed the highest satisfaction as 3.99; and toothpaste 3 (Zanthoxylum schinifolium, Spearmint) showed the lowest satisfaction as 3.56. Conclusion: Four kinds of natural herbal toothpaste showed higher satisfaction as 3.99. In particular, the toothpaste adding Zanthoxylum schinifolium and Lemongrass extracts.

In this study, sections of twenty eight teeth were used to investigate the effect of topical application of $8\%$ stannous fluoride on the decalcification rate of enamel surfaces stripped in a manner suggested for orthodontic purpose. The enamel treated with a single application of a fluoride had a significantly lower tile rate of decalcification for the first 96 hours to lactate buffer solution. After double application of fluoride, decalcification rate decreased signicantly. This study suggested that the continuing protection of stripped surfaces should be sought by regularly scheduled treatment of the enamel with the topical application of fluoride and regular use of a fluoride containing dentifrice.

The steady shear flow properties of six kinds of commercial toothpastes were measured using a concentric cylinder type rheometer. In this paper, the shear rate and temperature dependencies of their flow behavior were investigated and the validity of the Casson and Herschel-Bulkley models was examined. Further, the flow properties over a wide temperature range were quantitatively evaluated by calculating the various material parameters. Main results obtained from this study can be summarized as follows: (1) Toothpastes are plastic fluids with a yield stress and their flow behavior shows shear-thinning characteristics. (2) With increasing temperature, the degree of shear-thinning becomes weaker and the Newtonian flow behavior occurs at a lower shear rate range. (3) The Herschel-Bulkley model is more effective than the Casson model in predicting their flow behavior. (4) As the temperature increases, the yield stress, plastic viscosity and consistency index become smaller, on the contrary, the flow behavior index becomes larger.

Purpose: The present study was performed to evaluate the effect of hydroxyapatite dental paste on tooth hypersensitivity compared to other materials. Materials and methods: In the general fluoride dental paste, strontium fluoride dental paste and hydroxyapatite dental paste, patient-performed VAS and VAS(ice test) were measured at baseline, 1weeks and 4weeks. Results: 1. In patient-performed VAS, there were significant differences reducing of tooth hypersensitivity between general fluoride toothpaste and hydroxyapatite toothpaste. 2. In operator-performed VAS(ice test), there were significant differences reducing of tooth hypersensitivity among each group, between general fluoride toothpaste and hydroxyapatite toothpaste and between general fluoride toothpaste and strontium fluoride toothpaste. Conclusion: In conclusion, hydroxyapatite toothpaste can be applied for control of tooth hypersensitivity.

무선통신기술의 급속한 발달로 유.무선 기술을 이용한 네트워크 구축 및 서비스의 보급이 활발해지고 있다. 이러한 서비스 중에서 무선랜 서비스는 기존 유선 네트워크와의 호환성과 무선이 갖는 확장성으로 인해 많은 곳에서 널리 활용되고 있다. 현재 보급되고 있는 무선랜 제품은 802.1x, WPA 보안 표준을 구현한 제품들이 대부분을 차지하고 있으며, 최근 표준화가 완료된 802.11i 호환 제품들도 많이 보급될 것으로 예상된다. 또한 무선랜 통신의 고속화와 보안기술의 발전에 힘입어 유선구간에서 제공되던 많은 서비스들이 무선환경에서도 비교적 안전하게 서비스 될 것으로 예상된다. 그러나, 무선랜의 많은 장점에도 불구하고, 많은 기업과 기관에서 무선랜 설치를 망설이는 주요 이유 중의 하나는 무선랜의 보안치약성에 대한 우려 때문인 것으로 분석되고 있다. 물론 무선랜 구축을 위한 추가적인 비용 문제도 있지만, 특히 무선이 유선에 비해 보안이 상대적으로 취약하다는 문제를 제기하고 있다. 이에 따라 NIST, DoD 산하 ITRC 및 캐나다의 CSE 등에서는 무선랜 환경에서의 보안취약성 및 모범 사례들을 제시하고 있다. 국내의 경우에는 한국정보보호진흥원에서 무선랜 보안 운영 실태조사를 바탕으로 국내 무선랜 서비스 형태 및 구축방식에 따른 보안대책을 공표 하였으며, 일반인을 대상으로 한 안전 운영 가이드라인을 마련하고 있다. 본문에서는 국외 무선랜 보안 대책을 소개하고, 무선랜 환경에서의 침해사고를 예방하기 위한 국내 가이드라인의 주요 내용 및 방향을 제시한다.
