This research surveyed 324 college students majored dental hygiene in Gwangju and Chonnam province to analyze their awareness and degree of practice about infection control. Through the study for recognition about infectious disease related with the grade, the sophomore students are the group who is the most aware. In addition, the study shows students who experienced teeth cleaning have high degree of awareness (p<0.05). The research of perception about infectious disease based on experiences for vaccinations and education about infection prevention says hepatitis B has the highest rate when it comes to level of occurrence risk and tuberculosis and acquired immune deficiency syndrome are the lowest (p<0.05). According to the research, the group who had vaccination, knowledge about infection prevention and experience for scaling shows high practice rate for hand washing according to whether students receive protective inoculation or not. Depending on what the result were, since student learned about infection control has high degree of recognition and practice about infection management if we could emphasize the importance to students through regulative education about infection control and then increase the degree of practice, it would make big contributions to the effective infection control.
Objective : To estimate the prevalence of congenital heart disease from the 1990 student heart disease screening program. Methods : The heart disease screening program for elementary students was conducted in Kyonggi-do, in 1998. The subjects of the present study comprised the 40,402 students who attended the schools in the catchment area of a collaborative university hospital and who participated in the primary examination. The congenital heart disease (CHD) patients were initially identified through a questionnaire about prior medical history, and further through diagnostic tests & medical examinations in the secondary & the tertiary examinations. Certain assumptions were used in the estimation of the number of CHD cases among non-participants of the secondary & tertiary examinations. The overall prevalence of CHD was estimated by adding the CHD detection rates of the participants and the estimated prevalence of the non-participants. Results : Among the 40,402 primary participants, 1,655 were referred further, of whom 79.1% (1,309) participated in the secondary examination. Of these, 121 were referred to the tertiary examination, with a participation rate at this last stage of 80.2%. The positive predictive value (PPV) of the screening tools was the highest when the results of both EKG and the questionnaire were positive. Because 85.9% of the detected cases had a past history of CHD, PPV was higher when the selection criteria in the questionnaire included past CHD history than when it didnt. The CHD defection rate among the participants was 1.76 cases/1,000 and the presumed number of cases among the non-participants was 31; giving an estimated final CHD prevalence of 2.52 cases/1,000 (95% CI : 2.06-3.06). Among the identified cases of CHD, VSD (52.8%) was the most common, followed by PDA (9.7%), TOF (9.7%) & PS (9.7%). Conclusion : Because the characteristics of the non-participants differed from those of the participants, the estimation of prevalence was influenced by the participation rate. Of the detected cases, 85.9% had a past history of diagnosis or operation for CMD. These findings suggested that the prevalence estimated in this study may be an underestimation of the actual condition. Therefore, a birth cohort study is required in order to more accurately estimate the prevalence and the effects of the program.
The present study was performed to investigate the prevalence rate of idiopathic scoliosis and to determine the effect of exercise training on scoliotic angle in elementary school children. In this study, two out of five elementary schools in Seosan city were chosen by random sampling. Seven hundred sixty four students (from four grade to the sixth grade student) were selected in two schools. Screening tests were conducted to find idiopathic scoliosis. Among the 764 individuals, 139 subjects who showed positive sign in physical examination took whole spine radiography. Thirty six subjects who had a curve of 10 or greater and consented to participate in the exercise program were selected for the exercise program. The exercise program was performed four times a week for 5 months. The results of this study were as follows: 1) One hundred thirty nine subjects showed positive sign in the scoliosis screening test. 2) The overall prevalence of curve of $10^{\circ}or$ greater in X-ray finding was 8.15%. The prevalencies of curve of $10^{\circ}or$ greater in male and female were 7.1% and 9.2%, respectively. 3) Scoliosis curves were observed at thoracic area (48.4%), at thoracolumbar area (27.4%) and at lumbar area(24.4%). 4) Right side curve was 59.7%, and left side curve was 40.3%. 5) After the 5 month exercise program for scoliosis, the Cobb's angle was significantly decreased. 6) There was no significant difference of Cobb's angle change respect to sex, grades, and scoliosis curve site. Results shown here indicates that an early detection and early exercise for scoliosis can result in decreased the Cobb's angle in elementary school children.
Objectives: In most retrospective studies, the clinical performance of restorations had not been considered in survival analysis. This study investigated the effect of including the clinically unacceptable cases according to modified United States Public Health Service (USPHS) criteria into the failed data on the survival analysis of direct restorations as to the longevity and prognostic variables. Materials and Methods: Nine hundred and sixty-seven direct restorations were evaluated. The data of 204 retreated restorations were collected from the records, and clinical performance of 763 restorations in function was evaluated according to modified USPHS criteria by two observers. The longevity and prognostic variables of the restorations were compared with a factor of involving clinically unacceptable cases into the failures using Kaplan-Meier survival analysis and Cox proportional hazard model. Results: The median survival times of amalgam, composite resin and glass ionomer were 11.8, 11.0 and 6.8 years, respectively. Glass ionomer showed significantly lower longevity than composite resin and amalgam. When clinically unacceptable restorations were included into the failure, the median survival times of them decreased to 8.9, 9.7 and 6.4 years, respectively. Conclusions: After considering the clinical performance, composite resin was the only material that showed a difference in the longevity (p < 0.05) and the significantly higher relative risk of student group than professor group disappeared in operator groups. Even in the design of retrospective study, clinical evaluation needs to be included.

This study evaluated the validity and reliability of applying a newly developed dish-based, semi-quantitative food frequency questionnaire (FFQ) for Korean diet and cancer research. The subjects in the present study were 288 Korean adults over 30 years of age who had completed two FFQs and four 3-day diet records (DRs) from May 2008 to February 2009. Student's t-tests, Chi-square tests, and Spearman's rank correlation coefficients were used to estimate and compare intakes from different dietary assessment tools. Agreement in quintiles was calculated to validate agreement between the results of the second FFQ (FFQ-2) conducted in February 2009 and the DRs. Median Spearman's correlation coefficients between the intake of nutrients and foods assessed by the FFQ-1 and FFQ-2 were 0.59 and 0.57, respectively, and the coefficients between the intake of nutrients and foods assessed by the FFQ-2 and the DRs were 0.31 and 0.29, respectively. The quintile classifications of same or adjacent quintile for intake of nutrients and foods were 64% and 65%, respectively. Misclassification into opposite quintiles occurred in less than 5% for all dietary factors. Thus this newly-developed, Korean dish-based FFQ demonstrated moderate correspondence with the four 3-day DRs. Its reliability and validity are comparable to those reported in other studies.
The Korean pharmacy education has introduced new curriculum since 2011. In the new curriculum, pharmacy students have been provided strenthen experimental education and clinical pharmacy has been more important than previous curriculum. Thus, faculties in the college of pharmacy should prepare the circumstances correlated with the changed curriculum. To accomplish successful setting, all faculty and practice experts must work together and need financial assisstant from the college. However, there are many different obstacles among 35 colleges of pharmacy in Korea. In order to narrow a gap among students and find the way to overcome it together, we studied the problem of preparation process in Korean colleges of Pharmacy. We studied the process of practical education in college of pharmacy by means of self-reporting questionnaire from November 29th 2012 to December 31th 2012. The questionaire comprised of syllabus related to clinical pharmacy, the number of professor in charge of clinical pharmacy or pharmacotherapeutics, the plan of securing faculties in the field of clinical pharmacy, the budget, site, instrument for preparing experimental education, the lesson time number of experimental education, MOU, education and treatment of preceptor in the practice site and committee of experimental education in the college. Total 21 of 35 colleges participated in this survey. They showed different composition of syllabus, budget, the circumstances of experimental education, the education and treatment of preceptor. Most colleges are unclear the site and preceptor of experimental education and they did not contract the MOU with the sites. 9 of 21 also did not have the committee of experimental education in the colleges. From 2013, some colleges of pharmacy start actual experimental education. Inadequete preparation and different quality of education can make student incomplete pharmacists, so it will be negative effect on public health. To overcome challenge and obtain desirable goal, funding/administrative assistant from the college and networking within 35 colleges of pharmacy are needed.

PURPOSE. Porcelain fused to metal (PFM) crowns provide the best treatment option for teeth that have a large or defective restoration. More than 20% of teeth with PFM crowns or bridges require non-surgical root canal treatment (NSRCT). This may be due to the effect of restorative procedures and the possible leakage of bacteria and or their by-products, which leads to the demise of the tooth pulp. Thus, this study was planned to compare the ability of the restorative materials to seal perforated PFM specimens. MATERIALS AND METHODS. The study evaluates the ability of amalgam, composite or compomer restorative materials to close perforated PFM specimen's in-vitro. Ninety PFM specimens were constructed using Ni-Cr alloys and feldspathic porcelain, and then they were divided into 3 groups: amalgam (A), composite + Exite adhesive bond (B) and compomer + Syntac adhesive bond (C). All the PFM samples were embedded in an acrylic block to provide complete sealing of the hole from the bottom side. After the aging period, each group was further divided into 3 equal subgroups according to the thermocycling period (one week for 70 cycles, one month for 300 cycles and three months for 900 cycles). Each subgroup was put into containers containing dye (Pelikan INK), one maintained at $5^{\circ}C$ and the other at $55^{\circ}C$, each cycle for 30 sec time. The data obtained was analyzed by SPSS, 2006 using one way ANOVA test and student t-test and significant difference level at (P<.01). RESULTS. The depth of dye penetration was measured at the interfaces of PFM and filling materials using Co-ordinate Vernier Microscope. The lowest levels of the dye penetration for the three groups, as well as subgroups were during the first week. The values of dye leakage had significantly increased by time intervals in subgroups A and C. CONCLUSION. It was seen that amalgam showed higher leakage than composite while compomer showed the lowest level of leakage.
This study examines the effects of consumer socialization on Korean adolescent impulsive buying behavior. The current study used the third and sixth waves from the Korean Education and Employment Panel (KEEP) survey that has been administered by the Korea Research Institute for Vocational Education and Training since 2004. The subjects were high school juniors and university sophomores in 2006 and 2009, respectively. The final sample for panel regression analysis included 1,718 individuals. Two major agents of socialization (school and parents) were utilized in our model. Parent financial behavior (if the parents had savings) and the effectiveness/helpfulness of economics education in middle or high school were included in our estimation model. Two categories were included as individual factors: (1) psychological aspects and personal traits covering variables such as stress from self-image, academic stress, self-regulation, and a tendency of risky behavior and (2) financial behavior and attitudes, which include work experience, amount of money in hand, shopping habits, and if parental financial support is expected after high school graduation. The results from a random effects model revealed that the effects of consumer socialization through school was marginally significant, while through parents was not. Stress from self-image and the level of self-regulation were found to be significant. Neither risky behavior nor academic stress were a significant factor for impulsive buying behavior. The amount of money available in hand and shopping habits showed a significant influence. Implications for educators, parents and policy makers are identified.

Background: Early initiation of smoking and chewing of diverse forms of tobacco among youth in India is a significant driver for tobacco epidemic in India. Several socio-demographic factors are predictors of tobacco use in populations, especially among youth. Interventions which address these socio-demographic factors can help policy makers to curb new initiations and avert morbidity and mortality due to tobacco use. Objective: To study the various sociodemographic variables associated with tobacco use among youth in India. Materials and Methods: Secondary analysis of data from the Global Adult Tobacco Survey-India 2009-10 for the age group of 15-24 years was performed and predictors of smoking and smokeless tobacco were analyzed using data on occupation, education, and other sociodemographic factors. Results: In India there are a total of 51.3 million (22.1%) youth (15-24 years) tobacco users. Of these 35.1 million consumes chewable tobacco (15.1%), 16.2 million smoke (7%) and 1.6 million are dual users (3.1%). Males, urban, less educated, un-employed and those belonging to middle class preferred smoking over chewing; whereas, females, rural, students and those belonging to low socio-economic class are predictors of smokeless tobacco use. The major determinants of dual users are male sex, poor socio-economic strata and student class. The overall tobacco use was higher among males, rural populations, lower socioeconomic strata and un-employed class. Conclusions: India's youth is more susceptible to the tobacco addiction, especially of smokeless tobacco. Youth from rural India especially students, girls and those from poor socio-economic strata prefer to use smokeless tobacco products whereas urban, male and those less educated prefer smoking tobacco products. More population-based and region-focused research is needed to understand initiation patterns into tobacco use among youth so as to inform policymakers to devise new policy measures to curb the growing epidemic.
Objectives: The purpose of the study was to investigate the satisfaction towards clinical training institution according to clinical practice contents in the dental hygiene students. Methods: A self-reported questionnaire was completed by 382 dental hygiene students of five colleges in Busan, Ulsan, and Gyeongsangnam-do from August 20 to September 30, 2013. The data were analyzed using SPSS WIN 20.0 program for t-test, one-way ANOVA, and Pearson's correlation analysis. The questionnaire consisted of the general characteristics of the subjects and the satisfaction towards the clinical training institution. The satisfaction was composed of 44 questions including the general satisfaction, practice contents, practice guide, training time of practice, training environment, practice evaluation, and personal relationship by Likert 5 point scale. Results: The students were most satisfied with the practice contents of the dental university hospitals. The dental hospital and dental clinics were the most satisfied choice in the personal relationships. Public health center dental clinics bestowed the students with the most satisfied practice guidance, time, environment, and evaluation. Practice contents and practice time were the most influential factors to dental hygiene department satisfaction to the students. Conclusions: In order to enhance the clinical practice satisfaction, it is necessary to have the continuous relationship with the clinical training institution. The practice satisfaction is influenced by the contents and environment of the clinical training institution.
