  • Purpose: The purpose of this study was to investigate the awareness of Korean unification and health care in healthcare professional students. Methods: Descriptive survey design was used, and self administered questionnaires were collected from 567 participants. The data were analyzed using descriptive statistics, chi-square test, ANOVA, and scheffe test. Results: A total of 279(54.4%) students answered that Korean unification is needed. The mean score of attentiveness to Korean unification was 5.27(${\pm}2.10$) out of 10, and the mean score of interest on health care for unification was 4.28(${\pm}2.26$). The degree of interest in Korean unification was significantly associated with the degree of health care for unification(p<.001). The mean score of necessity regarding health care education for unification was 5.59(${\pm}2.15$) out of 10, which was proportional to the degree of interest in the Korean unification(p<.001). The mean score of knowledge regarding North Korea's medical status was 2.35(${\pm}1.17$) out of 10. Conclusion: Based on the study results, continuous education about unification as well as health care for unification is required in order to increase awareness of Korean unification and healthcare in students. Furthermore, additional studies to better understand nursing care systems of North Korea and to identify the roles of nurses in the unification process and public healthcare of unified Korea are needed.

  • Objectives: The aim of this study was to investigate the ability of the fluorescence-aided caries excavation (FACE) device to detect residual caries by comparing conventional methods in vivo. Materials and Methods: A total of 301 females and 202 males with carious teeth participated in this study. The cavity preparations were done by grade 4 (Group 1, 154 teeth), grade 5 (Group 2, 176 teeth), and postgraduate (Group 3, 173 teeth) students. After caries excavation using a handpiece and hand instruments, the presence of residual caries was evaluated by 2 investigators who were previously calibrated for visual-tactile assessment with and without magnifying glasses and trained in the use of a FACE device. The tooth number, cavity type, and presence or absence of residual caries were recorded. The data were analyzed using the Chi-square test, the Fisher's Exact test, or the McNemar test as appropriate. Kappa statistics was used for calibration. In all tests, the level of significance was set at p = 0.05. Results: Almost half of the cavities prepared were Class II (Class I, 20.9%; Class II, 48.9%; Class III, 20.1%; Class IV, 3.4%; Class V, 6.8%). Higher numbers of cavities left with caries were observed in Groups 1 and 2 than in Group 3 for all examination methods. Significant differences were found between visual inspection with or without magnifying glasses and inspection with a FACE device for all groups (p < 0.001). More residual caries were detected through inspection with a FACE device (46.5%) than through either visual inspection (31.8%) or inspection with a magnifying glass (37.6%). Conclusions: Within the limitations of this study, the FACE device may be an effective method for the detection of residual caries.

  • The present study investigated the risk and prevalence of dysphagia as well as related factors among free-living elders. Subjects were 419 elderly men (116) and women (303) aged 65 years and older ($74.49{\pm}4.70y$) living in Seoul, Gyeonggi-do and Chungcheongbuk-do area in Korea. Data were collected by personal interviews using questionnaires and analyzed by descriptive statistics, t-test, and chi-square test. Prevalence of dysphagia was 53.50% among participants. Risk of dysphagia was significantly different according to age (P<0.001), use of dentures (P<0.05), and activities of daily living (P<0.05). Moreover, dysphagia risk group had significant food intake problems, including poor appetite, smaller portions to reach satiety, frequent meal skipping, as well as poor taste compared to the normal group, accompanied by high risk of weight loss as assessed by simplified nutritional appetite questionnaire (P<0.01). Taken together, risk of dysphagia was more prevalent in older people, affecting the majority of those living independently in the community. This could indicate an association with undernutrition due to factors affecting food intake.
