This study aimed to investigate the effects of learning with role-playing on student satisfaction and achievement regarding behavior management teaching in pediatric dentistry. 93 students were divided into 19 groups and randomly assigned to role-play as a doctor, patient, parent, assistant, or narrator. Their performances were evaluated by the instructor and the satisfaction survey was conducted. All participants took the written test and were asked to compare lecture and role-playing with regard to the effectiveness of learning. Statistical analysis was performed with Mann-Whitney U test, Independent T-test, and Kruskal-Wallis test. 68 students (73.1%) who believed that the role-playing was more helpful than lecture showed higher level of satisfaction than students who believed lecture was more helpful. But there were no differences in the tutor evaluation score and the written test scores. Participants in the patient management scenario showed higher level of descriptive question scores of the written test and tutor evaluation score than those who participate in the parent management scenario. There were no differences between the role groups. Role-playing may help students to become more interested and participatory in learning behavior management. The level of satisfaction may differ by the design and content of the scenario.

This study was undertaken to recommend a dementia education program for college students, and to understand the outcome on knowledge and attitude towards dementia, awareness of aged support, and cognitive-affective empathy. Totally, 40 college students in C city, K do, were enrolled for the study, and divided into two groups of 20 each: experimental group and control group. The experimental group subjects were provided a 12-hour dementia education program; effectiveness of this program has been verified in later studies. Data were collected from November 5, 2018 to December 7, 2018; collection was before, after, and 4 weeks after the program was provided to the experimental group. Control group data were also collected in the same time frame. Data analysis was done using IBM SPSS WIN/21.0, and the percentage, mean and standard deviation were analyzed using Shapiro-Wilks test, $x^2$-test, Fisher's exact probability test, Independent t-test, Friedman test, Mann-Whitney U and Repeated Measure ANOVA. Knowledge of dementia (F=19.80, p<0.001), attitude toward dementia (z=-4.10, p<0.001), and awareness of aged support (F=6.26, p=0.017) had a significant interaction between group and time; however, cognitive-affective empathy showed no correlation (F=1.32, p<0.256). We therefore suggest strengthening the contents of future education program for dementia, developing a customized program for cognitive-affective empathy by considering subject characteristics, and further research verifying the effectiveness of the program.

This study was intended to evaluate condyle position and the relationship of condyle position change and post surgical relapse following the sagittal split ramus osteotomy for mandible setback in 25 patients by paired t-test and multiple regression analysis. We used oblique transcranial and cephalometric radiographs taken before operation, immediate after operation, and at least 6 months post operatively. 1. In oblique transcranial view, posterior joint space was decreased immediate after operation and increased 6 months after operation. To compare the measurement before and 6 months after operation, there was no statistically significant change in over all joint spaces(P>0.05). 2. The joint spaces changed under the 0.2mm were 30%, 0.2mm to 1.0mm were 60.7%, above 1.0mm were 9.3%. This result reveals that condyle position was relatively reproduced to pre-operative state. 3. Statistically, the amount of mandible set back didn't influence the post operative relapse(P>0.05). 4. Statistically, the amount of mandible set back didn't influence the condylar displacement(P>0.05), and the amount of joint space change didn't influence the post operative relapse.(P>0.05) The changes in joint space is in the standard tracing error or within the adaptive capacity of the individual, it was too small to influence the stability of surgery.

In comparison with the long and continuous his-tory of research in the general area of stress and coping, theoretical and clinical interest in family stress and adaptation is a recent phenomenon. To understand the phenomena of family behavior, a comprehensive theoretical framework is needed to us provide an adequate background to for research. This study was designed to develop and test a hypothetical model for family stress and adaptation in families with handicapped children. A hypothetical model was constructed on the basis of the family stress theory developed by McCubbin etc. The model included six paths. For the purpose of model testing, empirical data was collected from May to August, 1992. The subjects of the study were 190 parents of chidren in five special schools and one private institute in Seoul and Choong Nam. An SPSS P $C^{+}$ and PC-LISREL 7.13 computer programs were used for descriptive and covariance structure analysis. The results of the study are as follows. (1) Family Stress(${\gamma}$$_{3l}$=-.288, T=-4.942) had a direct effect on Family Adaptation. (2) Family Functioning ($\beta$$_{21}$=-.373, T=5.595) had a direct effect on Situational Definition. (3) Family Functioning ($\beta$$_{31}$ =.334, T=5.375) had a direct effect on Family Adaptation. (4) Situational Definition( a2=.270, T=4.285) had a direct effect on Family Adaptation The model was supported by the empirical data. Thus it is suggested that the model could be adequately applied to family nursing care of families with a mentally handicapped child. In particular, the nursing interventions that enhance family functioning and the situational definition would improve family adaptation in families with mentally handicapped children.n.n.

Prevention of exhaust gas back flow becomes a great interest to shipyards and shipowners in large container carriers because exhaust gas pollutes cargoes, flows back into the deck house and the engine room area through fresh air intakes and fan rooms, gives harmful damages to the crew's health and also gives thermal damages to electric equipments on the navigation deck. The phenomena of exhaust gas back flow has been studied with the analysis of sea trial records and wind tunnel tests and the height of the exhaust gas pipe, the front area of the deck house, the inflow speed and the position of the radar mast platform has been confirmed as the principal factors of exhaust gas back flow phenomena. The simple empirical formula to estimate exhaust gas back flow phenomena and the design guidances of exhaust gas related structures on deck has been introduced. In future, parametric studies for the exhaust gas back flow factors will be carried out with the CFD analysis. The results of this study will be the guide for development of the prevention method of exhaust gas back flow phenomena for large container carriers.

A female Green iguana (Iguana iguana) was brought to the small animal clinic in Hannover Veterinary school because of anorexia and convulsion. Two months ago, the owner bought two iguanas, one female and one male and had to take a female to the one of local small animal clinic because she, born in 19931 didn't eat well and showed the tremor of the legs. The veterinarian suspected it to have a calcium deficiency and gave an injection of calcium and vitamin D3. But still during the last two months, the female iguana did only eat some lettuce while the other male ate lettuce, fruits and commercial cat-food ($Whiskas^{\circledR}$, Effem, Verden). It was not possible to evaluate the rations of these different "food-components". They are kept in the terrarium with water container. By palpation of the abdomen, hard thing like stone was palpated in the mid-region. The blood test wasn't carried out because of the difficulties of getting blood and because of her bad condition. It was firmly diagnosed as cystic calculus through radiography. Since the animal is in shock state already, the prognosis after surgery was bad. It was assumed to be too late to expect its surviving with the surgery carried out or without it. Cystotomy was performed in the cranial ventral paramedian incision in order to preserve the large ventral abdominal vein in the linen alba region. After two stay sutures ("holding suture" ) with 5-0 polyglactin 910 ($Vicryl^{\circledR}, Ethicon$) on the bladder, cystotomy was carried out and the stone inside was removed. Then, the bladder was closed in one-layer sutures. The abdomen was closed in simple interrupted suture with same material after the instillation of 10 ml saline solution into the abdominal cavity. The cystic calculus was in a size of $5.8{\times} 5.O{\times} 3.5 cm$. The analysis of the stone was carried out in two ways which are the infrared spectroscopy of the stone and quick analysis by $Merckognost^{\circledR}$(Diagnostica Merck, Merck). In the result of the infrared spectroscopy, the stone wee composed of 10% ammonium urate and 90% dihydrated uric acid. This iguana wasn't able to survive.n't able to survive.

In GMAW, the spatter is generated because of the variation of the arc state. If the arc state is quantitatively assessed, the control method to make the spatter be reduced is able to develop. This study was attempted to develop the optimal model that could estimate the arc state quantitatively. To do this, the generated spatters was captured under the limited welding conditions, and the waveforms of the arc voltage and of the welding current were collected. From the collected waveforms, the waveform factors and their standard deviations were produced, and the linear and non-linear regression models constituted using the factors and their standard deviations are proposed to estimate the arc state. the performance test to the proposed models was practiced. Obtained results are as follow. From the results of correlation analysis between the factors and the amount of the generated spatters, the standard deviations of the waveform factors have more the multiple regression coefficients than the waveform factors. Because the correlation coefficient between T and {TEX}$T_{a}${/TEX}, and s[T] and s[{TEX}$T_{a}${/TEX}] was nearly one, it was found that these factors have the same effect to the spatter generation. In the regression models to estimate the arc state, it was fond that the linear and the non linear models were also consisted of similar factors. In addition, the linear regression model was assessed the optimal model for estimating the arc state because the variance of data was narrow and multiple regression coefficient was highest among the models. But in the welding conditions which the amount of the generated spatters were small, it was found that the non linear regression model had better the estimation performance for the spatter generation than the linear.

The purposes of this research were 1) to identify shopping orientation according to customer's personality type, 2) to examine perceived importance of service and satisfaction of service related to customer's personality type, 3) to find the relationships of evaluation of salesperson's service and re-purchase intention in each of customer's personality types. The data were collected via self-administered questionnaires from 434 female formal wear shoppers. and were analyzed by frequency, factor analysis, ANOVA, Chi-square test, and multiple regression analysis. The results of this study were as follows: Shopping orientations varied according to customer's personality type. E type had stronger Hedonic/self-confidence than I type, F type had higher Depending decision making than T type and P type had higher Quick decision making than J type. And service items satisfied the customers with a certain personality type. E type was satisfied with timely and proper A/S, not forcing to purchase and trustful behavior of salesperson more than I Type was. And also with expertise, individualized care, polite attitude, and merchandising promotion. N type was satisfied with individualized care more than S type was. A service evaluation criterion affected the re-purchase intention for a customer with a certain personality type. Customer's convenience in E. I. S, N, T, F, J types had a significant effect on re-purchase intention. And Expertise/ care in E, N, T, J types had a positive effect on re-purchase intention. also Politeness in E, I, S, N, T, J, P types did. But in only E type, Merchandising promotion affected re-purchase intention.

Objectives: To analyze correlation between CSEI-S and MMPI-2 subscales to provide evidence for clinical application of the CSEI-S. Methods: Survey data of CSEI-S and MMPI-2 from 109 university students were analyzed. Demographic characteristics were subjected to descriptive analysis. Mann-Whitney U test and Pearson's correlation analysis were performed for CSEI-S and MMPI-2 scores. Results: The CSEI-S scale Joy (喜) showed a negative correlation with MMPI-2 clinical scales Hs, D, Hy, Pd, Pa, Pt, Sc, and Si. Six negative emotion scales of the CSEI-S showed positive correlations with MMPI-2 clinical scales except Mf and Ma. The CSEI-S scale Joy (喜) showed negative correlations with MMPI-2 restructured clinical scales RCd, RC1, RC2, and RC7. Six negative emotion scales of the CSEI-S showed positive correlations with restructured MMPI-2 clinical scales. The 60T-and-over group of MMPI-2 clinical scales D, Pd, Pa, Pt, Sc, Si, and Si showed significantly higher negative emotions than other groups. The 60T-and-over group of MMPI-2 scales D, Pt, Sc, and Si showed significantly lower Joy (喜) score than other groups. The 60T-and-over group of MMPI-2 restructured clinical scales RCd, RC2, RC3, RC6, RC7, RC8, and RC9 showed significantly higher negative emotions than other groups. The 60T-and-over group of MMPI-2 scales RCd, RC6, and RC7 showed significantly lower Joy (喜) scores than others. Conclusions: The CSEI-S showed consistent results with the original CSEI and MMPI-2 subscales. Thus, is a useful diagnostic tool in clinical practice.
