Objectives : To propose the data for prevention of oral health problems through assessment on the knowledge, cognition and practice about oral health care of the clients who visit dental clinics. Methods : The subjects were total 400 clients from the four dental clinics in Busan city. Their knowledge, cognition and performances about oral healthcare collected with questionnaire survey from February to March, 2011. The rate and mean compared by chi-square test, t-test, and ANOVA. Results : Mean level of their knowledge, recognition and practice were 72.5, 80.2, and 65.6, respectively. Theses levels were higher in women (p<0.01), in the group of higher interested (p<0.001), immediately treated (p<0.001), correct tooth brushing (p<0.05), toothbrushing educated (p<0.001), take regular scaling (p<0.001), use assistant hygiene items (p<0.001), instead no differences by age and education level. And, the rate of correct toothbrushing was higher as 1.24 (1.03~1.50) times in the group with higher knowledge level, the rate of immediate treatment and regular scaling were higher as 1.35 (1.07~1.70) times, and 2.26 (1.41~3.64) times in the group with higher recognition level, respectively. Conclusions : These results demonstrate that insufficient knowledge and recognition of oral health care are related to a lack of its practice. Though their primary goal of the visits was treatment, the clients' attention needed to raise the comprehensive knowledge and recognition levels for their oral health promotion, especially reach to the performance level rather than simple knowledge acquisition. And more, to achieve the efficient oral health promotion, the importance of early treatment and strengthened efforts for prevention should be emphasized.

This study was performed to explore the effect of customer satisfaction and switching barriers on customer royalties in medical services. 900 households, 1% sample were randomly selected from K city located in Kangwon province. Interview survey was performed with structured questionnaire for the entire people, 923 persons who experienced medical service utilization during one year before survey on time, september, 2002. In comparison of switching barriers by sociodemographic characteristics, lower income group and lower educated group showed the higher level of recognition level on availability of changing the service provider significantly. In terms of economic loss as one of switching barriers, the group of over aged 61, the lower income group and the lower educated group felt higher than other groups. Also, the time loss of switching barrier was recognized in 41-60 aged group and employee in service industry highly. For the perceived risk factor as another switching barrier, the high educated group showed the higher recognition level in performance risk and felt higher social risk than other groups. In analysis of customer satisfaction and loyalty levels by switching barrier components, the lower level of availability of changing the service provider and the higher level of recognition for economic and time loss, they showed the higher satisfaction and loyalty levels. In final step, multiple regression analysis showed the positive relationship between customer satisfaction, switching barrier and customer loyalties. Besides, the moderating effect of switching barrier in relationship between customer satisfaction and loyalties was significant and this results suggests that the influence of customer satisfaction to customer loyalties might be weakened in high level of recognition for switching barrier. In conclusion, perceived risk of economic and time loss as switching barrier is an important factor and should be considered in planning of marketing strategy carefully in terms of defensive marketing.

음성인식 서비스는 청각장애인에게 화자의 음성을 텍스트로 변환하여 시각화함으로써 의사소통의 보조적인 수단으로 사용되고 있다. 하지만 강의실 및 회의실과 같은 개방된 환경에서는 다수의 청각장애인에게 음성인식 서비스를 제공하기 힘들다. 이를 위해 주변 환경에 따라 음성 인식 서비스를 효율적으로 제공하기 위한 방법이 필요하다. 본 논문에서는 화자의 음성을 인식하여 변환된 텍스트를 다수의 청각장애인에게 메시지로 전달하는 시스템을 제안한다. 제안하는 시스템은 다수의 사용자에게 동시에 메시지를 전달하기 위해 MQTT 프로토콜을 사용한다. MQTT 프로토콜의 QoS level 설정에 따른 제안 시스템의 서비스 지연을 확인하기 위해 종단 간 지연을 측정하였다. 측정 결과 가장 신뢰성이 높은 QoS level 2와 0간의 지연이 111ms로 대화 인식에 큰 영향을 끼치지 않음을 확인하였다.
