Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

Impact and process evaluations were performed in order to verify the effectiveness of a public health nutrition program developed for child-bearing aged women in Korea. Participants included 58 high school girls who were divided into two groups. Each group received four 50 - 60 minute nutrition education lectures regarding healthy eating, osteoporosis, constipation and nutrition labeling in every two weeks. Each session took 50 - 60 minutes. Regarding nutrition knowledge, there was a significant increase of degree of perception (p = 0.0004), but no change in degree of accuracy after implementation (p = 0.9522). Nutrition education was also effective in attitude change, showing more participants were ready to change their eating behaviors in terms of meal regularity (p = 0.0455) and less processed food intake (p = 0.0143). After implementing nutrition education, effective behavioral changes were observed in milk consumption (p = 0.0037) and meal regularity (p = 0.0882) as well as daily activity such as stair use (p = 0.0701). However, nutrition education had no effect on body mass index and perceived health status. In process evaluation conducted by a 9 item questionnaire, grand mean score was 4.17 +/- 0.72 out of 5. Proportion of items with scores higher than 4 ranged 68-91%. These results suggest that the nutrition education program used in this study was effective and useful. For a wider use of this program, more research was recommend for a strategy development of program diffuse.

PURPOSE: This study aimed to investigate the degree of role conflict and its ambiguity, and fatigue in clinical nurses and to analyze the effect of these on their self-resilience in order to provide fundamental data for improving their working environment after the Middle East Respiratory Syndrome outbreak. METHODS: After the collection of data from 258 clinical nurses in five general hospitals, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression were performed using IBM SPSS Statistics 20.0. RESULTS: A significant positive correlation was found between nurses' role conflict and ambiguity and fatigue; while a negative correlation was found between nurses' role conflict and ambiguity and self-resilience. A significant negative correlation was found between fatigue and self-resilience. According to the study results, the factor that affected clinical nurses' self-resilience the most was role conflict and its ambiguity, followed by marital status, fatigue, educational level, religion, and related tasks, which together accounted for 38% of self-resilience in clinical nurses. CONCLUSION: To improve weaknesses in nursing care after the Middle East Respiratory Syndrome outbreak, the scope of nursing care was changed upon the expansion of integrated nursing and care-giving services. Therefore, in the rapidly changing environment of nursing, policies to improve nursing performance, as well as successful reaction capability, are suggested.

The intervention elements of 28 selected studieswere categorized into 4 themes. The extracted intervention elements were divided into the themes of patient& situation-specific intervention, strengthen parent-child coping capacity and interaction, applyinggroup intervention and integrated intervention, Linkage with community resource and multidisciplinaryapproach. Conclusions The results demonstrate that social and psychological health of abused children has positivelychanged through these interventions. Therefore, it is important to implement treatment through active interventionaimed at helping the affected children.

PURPOSE: To identify factors affecting parenting stress of unmarried mothers. METHODS: The subjects were 108 unmarried women who were parenting their children under the age of six. The data was collected from December 15, 2016 to March 5, 2017. The instruments consisted of self-reported questionnaires that included93 items: 21 on depression, 16 on social support, 20 on health perception, and 36 on parenting stress. The collected data were analyzed by t-test, ANOVA, Pearson correlations, and hierarchical multiple regression. RESULTS: The factors influencing parenting stress were health perception (β=−.55, p < .001), evaluative support (β=−.42, p=.005), informative support (β=−.35, p=.040), emotional support (β=−.24, p=.045), partner support (β=−.20, p=.048), and depression (β=.14, p=.033), and the explanatory power was 57%. CONCLUSION: In order to alleviate the parenting stress of unmarried mothers, it is necessary to develop programs considering the physical, psychological, and social factors of unmarried mothers. Their subjective assessment of their health can increase or decrease their parenting stress, so it is necessary to develop parenting-stress intervention focusing on health perception.

Background: Proper detection and management of dental plaque are essential for individual oral health. We aimed to evaluatethe maturation level of dental plaque using a two-tone disclosing agent and to compare it with the fluorescence of dental plaque on the quantitative light-induced fluorescence (QLF) image to obtain primary data for the development of a new dental plaque scoring system. Methods: Twenty-eight subjects who consented to participate after understanding the purpose of the study were screened. Theimages of the anterior teeth were obtained using the QLF device. Subsequently, dental plaque was stained with a two-tone disclosing solution and a photograph was obtained with a digital single-lens reflex (DSLR) camera. The staining scores were assigned as follows: 0 for no staining, 1 for pink staining, and 2 for blue staining. The marked points on the DSLR images were selected for RGB color analysis. The relationship between dental plaque maturation and the red/green (R/G) ratio was evaluated using Spearman’s rank correlation. Additionally, different red fluorescence values according to dental plaque accumulation were assessed using one-way analysis of variance followed by Scheffe’s post-hoc test to identify statistically significant differences between the groups. Results: A comparison of the intensity of red fluorescence according to the maturation of the two-tone stained dental plaque confirmed that R/G ratio was higher in the QLF images with dental plaque maturation (p＜0.001). Correlation analysis between the stained dental plaque and the red fluorescence intensity in the QLF image confirmed an excellent positive correlation (p＜0.001). Conclusion: A new plaque scoring system can be developed based on the results of the present study. In addition, these study results may also help in dental plaque management in the clinical setting.

Background: Students in the department of dental hygiene are exposed to injections and sharp instruments during clinical practice. Therefore, it is necessary to develop measures for a safe practice environment. This study aimed to investigate dental stabbing accidents caused by dental instruments during clinical practice among students in the department of dental hygiene and suggest appropriate preventative measures. Methods: This study was conducted from May 1 to June 30, 2016, with students in the department of dental hygiene located at several universities in Seoul and Gyeonggi area. The study included 339 participants. A frequency analysis was performed to determine the general characteristics of dental infection control. A cross-analysis was conducted to identify the relationship between dental infection control education, stabbing accident prevention education, and treatment after stabbing accidents with a dental instrument. Results: Among the participants, 81.1% received dental infection control education and 66.4% received stabbing accident prevention education. Only 50.9% received hepatitis B vaccinations. Conclusion Dental infection control education and stabbing accident prevention education were shown to be effective in preventing dental instrument stabbing in students. However, post-accident processing, such as reporting to upper management and medical treatment after the accident, was insufficient. Therefore, it is necessary to present a treatment flowchart for dealing with stab accidents in clinical practice for students in the department of dental hygiene and strengthen education.
