  • Purpose : To compare the image quality and ligament traceability in ankle images obtained using Volume Isotropic Turbo Spin Echo Acquisition (VISTA) MRI with and without fat suppression. Materials and Methods: The signal-to-noise ratios (SNRs) in images from a phantom and from the ankle of a volunteer were compared. Ten ankles from 10 non-symptomatic volunteers were imaged for comparisons of contrast ratio (CR) and ligament traceability. All examinations were performed using VISTA sequences with and without fat suppression on a 3T MRI scanner. The SNRs were obtained from images with subjects and without subjects (noise-only). Contrast ratios from images of the 10 ankles were acquired between fluid and tendon (F-T), F-cartilage (C), F-ligament (L), fat (f)-T, f-C and f-L. Two musculoskeletal radiologists independently scored the traceability of 7 ligaments, in sagittal, axial and coronal images respectively, based on a 4-point scale (1 as not traceable through 4 as clearly traceable). The Wilcoxon signed-rank test was used to compare the CR. Fisher's exact test and Pearson's chi-squared test were used to compare the ligament traceability. Results: The SNRs did not differ significantly between the two sequences except in bone marrow. VISTA SPAIR showed the higher CR only in F-T (p = 0.04), whereas VISTA showed higher CR in f-T (p = 0.005), f-C (p = 0.005) and f-L (p = 0.005). The calcaneofibular ligament traceability with VISTA was superior to that obtained with VISTA SPAIR (p < 0.05) in all planes. Conclusion: VISTA showed significant superiority to VISTA SPAIR in tracing CFL due to the superior CR between fat and ligament.

  • The purpose of this study was intended to provide baseline data to develop child health education for multicultural mothers. Participants were 30 multicultural mothers in B city multicultural family support centers and 20 persons in charge of child healthcare in B city. From Dec 2016 to Jan 2017 a self-report instrument was used to measure general characteristics, status, importance, implementation, and needs of child healthcare education. The data were analyzed through frequencies, Chi-squared test, and analysis of variance using the SPSS 20.0 program. Fifty-seven percent of transcultural mothers had not participated in child healthcare education before. There was no significant difference between importance and implementation of child healthcare education. In Borich analysis, "Safety accident prevention", "Toilet training", and "Growth and development" were in the 25th percentile. In Locus for Focus, "Safety accident prevention", "Bathing", "Baby massage", "Toilet training", and "Weaning food" were in the HH area. In comparison with importance of child healthcare education, multicultural mothers, and persons in charge of child healthcare, multicultural mothers had significantly higher scores than persons in charge of child healthcare. Therefore, in order to meet multicultural mothers' educational needs for child healthcare education, child healthcare information should be developed.

  • This study was conducted to identify the diabetes self-care (DSM) knowledge, DSM competence, DSM behavior, and quality of life according to HbA1c control in diabetic elderly. The participants were 205 diabetes elderly who visited the citizen health promotion center located in D city, Korea. Data were collected from April, 4 to August 31 2015, and were analyzed by the t-test and chi-squared test using IBM SPSS 23.0. The mean scores of DSM knowledge, DSM competence, DSM behavior and quality of life were $50.61{\pm}16.39$, $71.27{\pm}10.21$, $62.78{\pm}1.29$ and $0.86{\pm}0.11$, respectively. Additionally, DSM behavior (t=2.17, p=0.031), education level (t=11.80, p=0.0019) l, BMI (t=0.001, p=0.012), and number of visits to citizen health center (t=16.497, p=0.001) differed significantly between the controlled HbA1c group and uncontrolled HbA1C group. However, ANCOVA revealed that the level of HbA1c did not affect the DSM behaviors. Therefore, it is necessary to develop and apply a DSM education program that reflects the characteristics knowledge level of the elderly. In addition, healthcare institutions with high accessibility in terms of distance and cost to guide and manage desirable diabetic self-care behaviors should be provided everywhere.

  • Purpose: To describe the profile of chronic and aggressive periodontitis among Senegalese (West Africans) attending the Institute of Dentistry of Dakar. Methods: A retrospective study was conducted with an inclusion period running from 2001 to 2008. The sample included 413 chronic periodontitis and 151 aggressive periodontitis cases, among them 299 males and 265 females selected from 2,274 records. A Student's independent t-test or Pearson chi-squared test was used for data analysis. Results: The proportion of females with aggressive periodontitis was significantly higher than those with chronic periodontitis (64.9% vs. 40.4%, P<0.001). The aggressive periodontitis patients had an average age of $28.1{\pm}8.9$ years, and had lost less than 3 teeth. Less than a third of them reported using a toothbrush. Attachment loss was as high as 8 mm and severe lesions had spread to an average of 12 teeth with maximum alveolar bone loss up to 80%. The chronic periodontitis patients had an average age of $44.9{\pm}14.0$ and had lost on average less than 3 teeth. Nearly 75% used a toothbrush. Attachment loss was significantly higher and lesions were more extensive in the aggressive periodontitis. Chronic periodontitis is associated with risk factors such as smoking or diabetes mellitus in 12.8% versus 0.7% in aggressive periodontitis (P<0.001). Differences between the two groups for most clinical and radiographic parameters were statistically significant. Conclusions: The profile of aggressive periodontist is characterized by more severe lesions than chronic periodontitis, whereas tooth loss experience is similar in both forms.

  • Turkey protects its entire population of 75 million people with all the MPOWER measures at the highest level. The aim of this study is to make a comparison of smoking and addiction data obtained from Sakarya University students in 2005-6 and 2012-13. A total of 4,200 (2,500 and 1,700 for each academic year) students at Sakarya University in Sakarya, Turkey, were randomly selected for sampling purposes. The selected participants represented Sakarya University students. Data were collected using a pretested anonymous and confidential, self-completed questionnaire which took 15-20 minutes to complete and Fagerstrom Test for nicotine dependence. Chi-squared, Spearman correlation, and binary logistic regression tests were used to define associations, if any. The level of significance was kept at alpha=0.05. Smoking prevalance dropped by 8.5% (from 26.9% to 18.5%). Male gender, older age, high family smoking index, low self-rated school success, and high peer smoker proportion were common variables that have correlation with smoking status. In the binary logistic regression test the highest contributor to "being a smoker" was found to be the rate of peer smokers. Having all friends smoking puts the student a a 47.5 and 58.0 times higher risk for smoking for males and females, respectively. Our results suggest an admirable diminution of smoking prevalance among Sakarya University students, which can be attributed to MPOWER protection.

  • Purpose: The purpose of this study was to identify associations among the sleep disturbance, fatigue, job stress, and blood and body fluid (BBF) exposure of shift-work nurses. Methods: A total of 299 shift-work nurses from two tertiary hospitals were enrolled in this study. We used the Insomnia Severity Index (ISI), and the Fatigue Severity Scale (FSS), and the Korean Occupational Stress Scale-Short Form (KOSS-SF) to evaluate sleep disturbance, fatigue, and job stress, respectively. The data were analyzed using t-test or chi-squared test and Logistic regression analysis using the SPSS 23.0 program. Results: We found that 43.8% of participants reported BBF exposure over the past year. Splash or exposure to broken skin of BBF were most frequent (56.9%), and followed by needlestick injuries (30.4%) and sharp injuries (12.8%). Age, hospital, working period, level of stress, sleep disturbance ($ISI{\geq}15$), fatigue (FSS $score{\geq}4$), job demand and organizational climate subset in KOSS-SF were significantly associated with BBF exposure in shift-work nurses. In multivariate analysis after adjusting age and hospital, the risk factors of BBF exposure in shift-work nurses were the level of stress and fatigue (FSS $score{\geq}4$). Conclusion: Fatigue and job stress were related to BBF exposure in shift-work nurses. Our results suggest that management of sleep disturbance, fatigue, and high job stress in shift-work nurses is needed to reduce risk of BBF exposure.

  • Rainwater has been used in many countries as a way of minimizing water availability problems. Rainwater harvesting system (RHS) has been successfully implemented as alternative water supply sources even in Korea. Although RHS is an effective alternative to water supply, its efficiency is often heavily influenced by temporal distribution of rainfall. Since natural precipitation is a random process and has probabilistic characteristics, it will be more appropriate to describe these probabilistic features of rainfall and its relationship with design storage capacity as well as supply deficit of RHS. This study presents the methodology to establish the relationships between storage capacities and deficit rates using probability distributions. In this study, the real three-story building was considered and nine scenaries were developed because the daily water usage pattern of the study one was not identified. GEV, Gumbel and the generalized logistic distribution ware selected according to the results of Kolmogorov-Smirnov test and Chi-Squared test. As a result, a set of curves describing the relationships under different exceedance probabilities were generated as references to RHS storage design. In case of the study building, the deficit rate becomes larger as return period increases and will not increase any more if the storage capacity becomes the appropriate quantity. The uncertainties between design storage and the deficit can be more understood through this study on the probabilistic relationships between storage capacities and deficit rates.
