Objectives : The study has three aims: 1) to assess the perceptions, attitudes, and behaviors of dental hygiene students and other college students towards oral and dental care, 2) to provide grounds for developing an oral and dental health educational program, and 3) to improve the oral and dental health status among the college student population. Methods : The subjects in this study were 520 students who included dental hygiene students from J health college and other majors from a four-year university located in Seoul. The survey was conducted from September, 2010, to June 3, 2011. The collected 507 questionnaires were analyzed. The collected data were analyzed by the statistical package SPSS WIN 12.0, and the level of significance was set at 0.05. Results : 1. As for a daily toothbrushing frequency, the largest number of the students brushed their teeth three times a day, and the dental hygiene students did that more often than the other majors(p<0.001). Concerning awareness of the toothbrushing method and the time for the change of the toothbrush, the rolling method was more prevailing among the dental hygiene students than the others(p<0.001). 2. In regard to education experience about the toothbrushing method and satisfaction with the existing toothbrushing method, 64.7% of respondents ever received education about the toothbrushing method(p<0.001). 3. As to scaling experience and gingival bleeding, the dental hygiene students had more scaling experiences(p<0.001), and the other majors who underwent gingival bleeding from time to time outnumbered the dental hygiene students who did(p<0.01). 4. In relation to subjective oral health status, the dental hygiene students found themselves to be in better oral health than the other majors(p<0.001), and the latter had more parts of the mouth in which they didn't feel well than the former(p<0.01). The dental hygiene students were more concerned about their oral health(p<0.001) and felt more uncomfortable in chewing(p<0.05). The other majors felt more uncomfortable in pronunciation(p<0.01). Conclusions : The results of this study indicated that dental hygiene students strongly recognized the importance of knowledge, motivation, and self-care behaviors, and attitudes towards oral health and dental care compared to other college students. It suggested that regular educational programs for the college student population should be implemented to increase their concern for oral and dental issues and to improve their oral and dental health status.

Objectives: The aims of the study were to examine perceived oral malodor and self-reported need for oral and dental care among patients receiving oral prophylaxis services and provide guidelines for developing educational programs(toothbrushing method and tongue cleaning) for oral hygiene and oral malodor prevention. Methods: The survey was administered to a sample of 462 receiving voluntary oral prophylaxis service in a dental laboratory at the J School of Public Health in Korea. The subjects were asked a range of questions related to the degrees of perceived oral malodor and concern for oral health status, as well as their demographic information and need for oral and dental treatment. Univariate analyses using Chi-square and T-test with a P-value of .05 were performed using SPSS Version 12.0 for Windows. Results: 1. Male participants reported moderately concerned for bad breath and smell and I don`t care bad breath and smell 39.1% and 26.2% respectively, while more female participants were concerned for oral malodor. moderately concerned for malodor and highly concerned for malodor 41.1% and 28.5%(p<.05). a significant difference among age groups was found. 19% of young adults (less than or equal to 29 years of age) reported highly concerned for bad breath and smell while 36.4% of older adults (greater than or equal to 50 years of age) reported highly concerned for bad breath and smell (p<.05). 2. 12 non-smoking participants (3.7%) and 15 smoking participants (10.8%) reported that they have perceived bad breadth and smell (p<.05). 3. Smoking participants reported a higher degree of need for oral malodor treatment than that of non-smoking participants 88.5% and 82% respectively(p<.05). 4. The participants who did regular toothbrushing more than 3 times a day reported no malodor, 77 % as compared to 66.7% of the participants who did regular toothbrushing 2 times a day. Toothbrushing 2 times a day reported either moderate malodor or sever malodor (p<.01). Participants with more frequent toothbrushing reported less oral and breath odor as compared participants with less frequent toothbrushing. Conclusions: The study suggested that there is a need to oral prophylaxis for prevention and toothbrushing and tongue cleaning method oral malodor care and oral health status.

본 연구는 고지방식이 섭취시 RS섭취가 장기능 및 혈액지방성분에 미치는 영향을 알아보고자 하였다. 생후 4주된 실험동물을 구입하여 6주간 고지방식이로 사육하여 성장 시킨후 RS함량이 다른 실험식이로 4주간 더 사육한 후 실험한 결과는 다음과 같다. 4주간의 실험식이를 섭취하였을 때 식이섭취량과 식이효율은 실험군간의 차이가 없었고, 대조군에 비해 RS30군에서 체중과 부고환지방무게가 유의적이지는 않으나 감소하는 경향이었다. 소장과 대장의 길이, 맹장의 무게는 실험군간의 유의적인 차이가 없었다. 분변내 수분함량을 보면 RS를 30%섭취한 군에서 유의적이지는 않으나 증가하였고, 실험식이 섭취후 3주째 측정한 장통과시간은 RS30군에서 감소하는 경향을 보였다. 대장세포의 증식은 RS30군에서 유의적이지는 않으나 증가하는 경향을 보였다. RS섭취량에 따라 총지방량, 중성지방량은 유의적으로 감소하였으나 콜레스테롤과 HDL-콜레스테롤량은 실험군간에 차이가 없었다. 이상의 결과에서 고지방을 섭취한 성장이후의 쥐에서 RS섭취는 유의적이지는 않으나 체중과 체내 저장지방, 장통과시간을 감소시키는 경향을 보였으며, 혈액 내 총지방량과 중성지방량을 유의적으로 감소시켰다. 그러므로 난소 화성전분의 섭취는 저열량원으로의 가능성을 보여주고 있으며, 고지방식이시 혈액내 총지방량과 중성지방을 낮추는 효과가 있는 것으로 사료된다. 그러나 이러한 효과는 dose dependent하지는 않았으며 난소화성 전분을 식이무게의 30%로 섭취할 경우에 유의적으로 나타났다. We have investigated the intestinal functions and hypolipidemic effects of resistant starch (RS) in rats. Experimental groups were CON (cooked starch 45%+RS 0%), RS10 (cooked starch 35%+RS 10%), RS20 (cooked starch 25%+RS20%), and RS30 (cooked starch 15%+RS 30%). The weight gains during experimental period were slightly decreased by intake of resistant starch and the weights of epididymal fat pad were lower in resistant starch intake groups than in CON, although the difference was not significant. In intestinal functions, water contents of fecal, transit time and colon cell proliferation were affected by resistant starch. Plasma total lipid and triglyceride concentrations were significantly decreased, dose-dependently, by resistant starch intake. Conclusively, it is important to intake resistant starch in order to decrease plasma lipids and to improve intestinal functions.
