The purpose of this study was to investigate the effects of maternal psychological control and the disparity between children's temperament and mothers' demand level on children's externalizing and internalizing behavior problems. The participants of this study were 221 children aged 4 to 5 and their mothers from three kindergartens located in Busan and Gyeongsangnam-do. To measure children's behavior problems, the Preschool and Kindergarten Behavior Scales were used. Maternal psychological control was assessed by the Psychological Control Scale-Youth Self-Report. The Revised Dimension of Temperament Survey and DOTS-R: ethnotheory was used, to measure the disparity between children's temperament and mothers' demand level. The data were analyzed by means of descriptive statistics, t-test and hierarchical regression analysis. The results of this study were as follows. First, both for boys and girls, the disparity between children's activity temperament and mothers' demand level had a negative effect on externalizing behavior problems. However, maternal psychological control had no significant effect on externalizing behavior problems both for boys and girls. Second, for boys, the high level of maternal psychological control and the disparity between children's adaptive temperament and mothers' demand level had a negative effect on internalizing behavior problems. However, for girls, such effects were not significant.

Objectives: The objective of this study is to investigate the relationship among professional self-concept, self-esteem and job satisfaction in the clinical dental hygienists and provide the basic data for the effective management of clinical dental hygienists. Methods: A self-reported questionnaire was filled out by 250 clinical dental hygienists in Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang Provinces from February 1 to March 30, 2017. Data were analyzed using IMB SPSS/WIN 22.0 program. Professional self-concept, self-esteem and job satisfaction according to the general characteristics and job characteristics were analzyed by independent t-test, one way ANOVA and Tukey. The relationship among professional self-concept, self-esteem and job satisfaction was found by Pearson's correlation. Multiple regression analysis was used to find out the relationship among professional self-concept, self-esteem and job satisfaction in the clinical dental hygienist. The significance level was a=0.05. Results: Clinical dental hygienist's professional self-concept was 3.76 points, self-esteem was 3.08 points and job satisfaction was 3.35 points. In general characteristics, professional self-concept showed the significant differences by age (p=0.043), marital status (p=0.005), level of education (p=0.001), duration of clinical career (p=0.003) and economic level (p=0.001). Job satisfaction showed the significant differences by age (p=0.019) and level of education (p=0.024). In job related characteristic, professional self-concept showed the significant differences by working area (p=0.001), working intensity (p=0.011) and position (p=0.001), while job satisfaction showed the significant differences by working area (p=0.014) and working intensity (p=0.001). Influencing factors in the job satisfaction in the clinical dental hygienists were age, working intensity, self-esteem, and professional self-concept. The explanatory of the model was 29.0%.

The aim of this study was to assess the oral health knowledge, attitude and behavior among geriatric care workers in long-term care facilities. A self-administered questionnaire was obtained from 212 geriatric care workers attending a professional education program of 2014 dementia pilot project. The questionnaire consisted of 4 parts of the training experience (2 items), knowledge (16 items), attitude (13 items), and behavior (4 items) on oral health care. Collected data were analyzed by frequency analysis, independent t-test, and one-way ANOVA using SPSS Statistics ver. 20.0. The percentage of educational experience on oral care was 27.9% and most respondents answered that they have received the education about denture cleaning (98.3%) and brushing method (91.4%). The average knowledge score was $10.88{\pm}1.70$, and respondents showed high-level agreement in 8 of the 10 items in attitude questions. They revealed difficulties in providing oral care to the elderly people because of their lack of knowledge. The deficiencies of knowledge about oral care would have a decisive effect on not only oral and general health, but also quality of life of the elderly people. Therefore, it is required to develop professional oral care training programs for geriatric care workers and support systems should be legalized.

This study examined the relationships among patient safety competence, critical thinking disposition, problem-solving competence, and self-efficacy of clinical nurses to identify the factors influencing the patient safety competence. A convenience sample of 373 nurses working in 4 general hospitals in a Metropolitan area in Korea was selected. After obtaining IRB approval, data collection was done with a structured self-administered questionnaire from October 14th to November 4th, 2014. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression analysis using the SPSS WIN 21.0 program. The participants showed a moderate level of patient safety competence ($3.75{\pm}0.37$), of critical thinking disposition ($3.43{\pm}0.27$), of problem solving competence ($3.54{\pm}0.30$), and of self-efficacy ($3.58{\pm}0.47$). The patient safety competence of the participants showed a significant correlation with the critical thinking disposition (r=.493, p<.001), problem solving competence (r=.616, p<.001), and self-efficacy (r=.475, p<.001). The significant factors influencing the patient safety competence were problem solving competence (${\beta}=.403$, p<.001), self-efficacy (${\beta}=.156$, p=.005), critical thinking disposition (${\beta}=.130$, p=.018), and having the experience of reporting patient safety accidents (${\beta}=.137$, p=.002). The results suggest that educational programs to enhance the critical thinking disposition, problem-solving competence, and self-efficacy would develop the patient safety competence of clinical nurses. In addition, more effort should be placed into reinforcing the patient safety competence by activating the report of patient safety accidents.

Statement of problem. There have been many studies about marginal discrepancy of single restorations made by various systems and materials. But most of statistical inferences are not definite because of sample size, measurement number, measuring , instruments, etc. And there have been few studies about the marginal fit of Computer-aided Cercon crowns. Purpose. The purpose of this study was to compare the marginal fit of the anterior single restorations made using computer-aided milled Cercon crowns with metal-ceramic restorations and to obtain more accurate information by using a large enough sample size and by making sufficient measurements per specimen. Material and methods. The in vitro marginal discrepancies of computer-aided milled Cercon crowns and control groups (metal ceramic crowns) were evaluated and compared. The crowns were made from one extracted maxillary central incisor prepared by milling machine. 30 crowns per each system were fabricated. Measurements of a crown were recorded at 50 points that were randomly selected for marginal gap evaluation. Parametric statistical analysis was performed for the results. Results. The means and standard deviations of the marginal fit were 85$\pm$22$\mu$m for the control group and 91$\pm$15$\mu$m for the Cercon crowns. The t-test of the marginal discrepancies between Cercon crowns and metal-ceramic crowns were performed. Significant differences were not found between groups (P=0.230>.05). Based on the criterion of 120$\mu$m as the limit of clinical acceptability, the mean marginal fits of Cercon crowns and metal-ceramic crowns were acceptable. Conclusion. Within the limitations of this in vitro study, the following conclusions were drawn: 1. Mean gap dimensions and standard deviations at the marginal opening for maxillary incisal crowns were 85$\pm$22$\mu$m for the control (metal-ceramic crowns), 91$\pm$15$\mu$m for Cercon crowns. 2. The Cercon crowns showed slightly larger marginal gap discrepancy than the control but marginal gap between Computer-aided milled Cercon crowns and metal ceramic crowns did not showed significant difference (P>.05). 3. The Cercon crowns and metal ceramic crowns showed clinically acceptable marginal discrepancy.

Purpose : Functional magnetic resonance imaging (fMRI) was used to assess the temporal response of neural activation in healthy subjects while they performed the Iowa Gambling Test (IGT), which utilizes decisions involving ambiguity and risk. The IGT was divided into five blocks of 20 trials; analysis showed that activity in the medial prefrontal cortex (mPFC) moves gradually from the dorsal to the ventral mPFC over the course of the IGT. These findings suggest that cognitive division of the mPFC, including the dorsal portion of the anterior cingulated cortex (ACC), plays a major role in ambiguous decision making and that the aspect of the IGT corresponding to risky decision making is associated with significant activity within the corticolimbic network strongly implicated in emotion and reinforcement. Our results also suggest that decisions made under ambiguity and decisions made under risk situations can be further divided into sub-phases based on the neural network involved.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.
