  • Purpose : To assess the height growth of children with epilepsy receiving antiepileptic drugs (AEDs) and the related factors. Methods : The subjects were 148 children diagnosed with epilepsy at Pusan National University Hospital between January 1996 and December 2003, who received AEDs for more than 3 y. We measured height at the initiation of AED medication and at the last visit during AED medication. We analyzed the mean height standard deviation score (SDS) according to several factors, including sex, age at initial medication, seizure type, underlying causes of epilepsy, seizure frequency before AED medication, seizure control, number of AEDs, height SDS before medication, and duration of medication. Results : In the total population, height SDS at initial therapy and last follow-up were $-0.06{\pm}1.39$ versus $0.10{\pm}1.12$ (P=0.09). Children with controlled seizures showed a significant increase in height SDS, from $-0.12{\pm}1.39$ to $0.10{\pm}1.09$ (P=0.04), and children on medication for less than 6 y showed a significant increase in height SDS, from $-0.09{\pm}1.54$ to $0.21{\pm}1.07$ (P=0.03). Also, children with negative initial height SDS showed a significant increase in height SDS (P<0.05). No height SDS changes were observed in any of the other groups, regardless of sex, seizure type, underlying causes of epilepsy, or age at initial medication. Conclusion : Neither epilepsy nor AED medication affects long-term height growth. Controlled seizure and short duration of AED medication are positive factors for height growth in children with epilepsy.

  • Objectives : In the field of dental hygiene, infections pose a serious problem. This issue has left many patients and dental staff exposed to microbes with potentially far-reaching effects. The purpose of this study was to find solutions which could improve Dental health policies and promote improved methods for the control of infections. This survey was conducted between March 3, 2008 and March 30, 2008, in the metropolitan area. The research was carried out in dental clinics and dental hygienists were surveyed through a questionnaire. Methods : Collected data was examined using the SPSS 14.0 program, using frequency, mean and standard deviation analysis, T-test, one-way ANOVA, Scheffe's test and Duncan's test. Further analysis was given using Logistic Regression. Results : The Performance of Infection Control by dental hygienists in Dental Clinics was shown at $2.96{\pm}0.42$. Disinfection, sterilization and the wearing of masks is high at $3.65{\pm}0.64$, $3.64{\pm}0.65$. The perception of the importance of infection control is higher among dental hygienists than dentists. Of the dental hygienists surveyed, 83.9% were exposed to at least one accident while at work. Age and years of experience were important in relation to infection control practices. The rate of infections and the number of accidents experienced related to the dental hygienists performance of infection control. The performance of infection control is influenced by the dental hygienists own perceptions, and the perceptions of their dentists. The dental hygienist's working conditions and their beliefs related to infection control were shown to influence their performance of infection control practices. Conclusion : At the conclusion of this investigation, it was determined that systematic refresher training of infection control should be delivered through further education and various media. Dental health care workers should be encouraged to practice these action items presented in the training. For successful implementation of infection control in every dental health-care setting, it is highly demanded that effective safe-guard tools, strategic support and standardized action items against infection problems are developed.

  • This study is a descriptive research study with the purpose of predicting and comparing factors of depression affecting residents in a metropolitan city by using logistic regression analysis and decision-making tree analysis. The subjects for the study were 462 residents ($20{\leq}aged{\angle}65$) in a metropolitan city. This study collected data between October 7, 2011 and October 21, 2011 and analyzed them with frequency analysis, percentage, the mean and standard deviation, ${\chi}^2$-test, t-test, logistic regression analysis, roc curve, and a decision-making tree by using SPSS 18.0 program. The common predicting variables of depression in community residents were social dysfunction, perceived physical symptom, and family support. The specialty and sensitivity of logistic regression explained 93.8% and 42.5%. The receiver operating characteristic (roc) curve was used to determine an optimal model. The AUC (area under the curve) was .84. Roc curve was found to be statistically significant (p=<.001). The specialty and sensitivity of decision-making tree analysis were 98.3% and 20.8% respectively. As for the whole classification accuracy, the logistic regression explained 82.0% and the decision making tree analysis explained 80.5%. From the results of this study, it is believed that the sensitivity, the classification accuracy, and the logistics regression analysis as shown in a higher degree may be useful materials to establish a depression prediction model for the community residents.

  • The purpose of this study is to investigate the relationship between emotional labor, resilience, and psychological well-being in clinical nurses, and to investigate ways to improve their psychological well-being. Data collection was conducted for nurses working in two general hospitals housing 300 beds in Incheon and Chungcheongnam-do. A total of 187 nurses were interviewed from June 10 to August 20, 2016. Data were analyzed using frequency and percentage, mean, standard deviation, t-test, analysis of variance (ANOVA), Pearson's correlation, and multiple regression analysis. In this research, 94.7% of the subjects were female, their mean age was 29.80, 61.5% of them had received associate of nursing degrees, and 70.6% were single. Results of the research showed that emotional labor averaged $3.37{\pm}.50hours$, resilience was $3.29{\pm}.45hours$, and psychological well-being was $3.25{\pm}.47hours$. There was a negative correlation (r=-.165, p<.05) between time spent on emotional labor and psychological well-being, and a positive correlation between time spent on recovery resilience and psychological well-being (r=.686, p<.01). Resilience was a predictor of psychological well-being, explained by a rating of 46.8% (F=164.43, p<.001). Based on the results of this study, developing a program that can improve resilience to improve the psychological well-being of clinical nurses involved in high emotional labor is suggested.

  • In this study, continuous long-term observation is implemented with an ocean radar. Ocean radar conducts remote observation (combined) with ground-based radars, which enable a series of simultaneous observations of an extensive range of the coast with high frequency. An ocean radar for continuous long-term observation is operated at Samcheok on the east coast of Korea. Samcheok experienced tsunami damage in recent years and is the location of a nuclear power plant. In order to examine the reliability of the ocean radar, a pressure-type wave gauge, ultrasonic wave gauge, and ocean buoy are installed for the purpose of data comparison and verification. The ocean radar used in this study is an array-type HF-RADAR named WERA (WavE RAdar). The analysis of the data obtained from continuous long-term observations showed that the radar observations were in agreement with more than 90% of the wave data collected within a 25 km range from the center of two sites. Less than 1% of the entire observation data was unmeasured by the time series analysis. As a result of comparing the radar data with the direct observations made by the wave gauge, it was inferred that the RMS deviation is less than 20cm and the correlation coefficient was in the range of 0.84 ~ 0.87. Moreover, supported by such observations, a comprehensive monitoring system is being developed to provide the public with real-time reports on waves and currents via the internet.

  • The patient radiation dose is different depending on selection of Ion chamber when taking Chest PA which using AEC. In this paper, we studied acquiring the best diagnostic images according to selection of Ion chamber on AEC mode as well as minimizing patient radiation dose. Experimental methods were selection of Ion chamber and change of sensitivity under the same conditions as Chest PA projection. At AEC mode, two upper ion chambers sensors and one lower ion chamber sensor were divided into 7 cases according to selection of on/off. after measuring five times respectively, we obtained average value and calculated exposure dose. Image assessment was done with measured Modulation Transfer Function, Peak Signal to Noise Ratio, Root Mean Square, Signal to Noise Ratio, Contrast to Noise Ratio, Mean to Standard deviation Ratio respectively. In exposure assessment results, selection of two upper chambers was the lowest. In resolution assessment results, image of two upper chambers had the second high spatial frequency at sensitivity at 625(High) was 1.343 lp/mm. RMS value of image selecting two upper chambers was low secondly. SNR, CNR, MSR were the high value secondly. As the sensitivity was increased, radiation dose was decreased but better image could be obtained on image quality. In order to obtain the best medical images while minimizing the dose, usage of two upper ion chambers is considered to be clinically useful at sensitivity 625(High).

  • The purpose of this study was to examine the relationship between emotional traumatic experience, stress, depression, and anxiety and to identify factors influencing suicide ideation. Data collection was carried out using a questionnaire survey administered to students from four health colleges in B city and a total of 289 questionnaires. Collected data were analyzed by frequency and percentage, mean, standard deviation, t-test, ANOVA, and multiple regression analysis using the SPSS/WIN program. The results show that there were significant differences in emotional trauma according to the general characteristics of the study subjects (p=.005) and stress related to grades (p=.029). Depression showed significant differences for gender (p=.020), religion (p=.022), and anxiety related to gender (p=.047). Suicidal thinking was not significantly different from the general characteristics. The suicidal ideation of the subjects was significantly correlated with emotional trauma (p<.001), stress (p<.001), depression (p<.001) and anxiety (p<.001). Factors affecting the suicidal ideation of the subjects were emotional trauma (t=4.117, p<.001), stress (t=2.909, p=.004), depression (t=3.421, p=.001), and anxiety (t=2.875, p=.004), and the explanatory power was 34.1%. This study can be used as basic data for the development of a suicide prevention program by identifying correlations between emotional traumatic experience, stress, depression, and anxiety related to suicide ideation and identifying factors affecting suicide ideation. Based on these results, the development of programs to reduce the college student suicide rate is necessary.
