Attitudes of parents toward behavior guidance techniques used in pediatric dentistry have changed for decades. Some techniques were regarded acceptable with authority of dentists' assistance, but now face the objection of caregivers. For the way of breeding is changing, dentist should understand the situation and try to communicate with caregiver for eliminating misunderstanding of the procedures that could induce lawsuit for abusive techniques. Most of all, dentist should try to find the best method for the patient and help to overcome the fear and anxiety. The meaningful knowledge driven from clinical experience should be shared with other dentists to build up sound theoretical foundation.

The purpose of this study is to obtain basic data needed to understand school-age children's parent-child communication style, stress coping behaviors, and child behavior problems. The subject of this study were 362 primary school children (the fourth and the sixth graders) and their mothers in "D" Metropolitan City, Korea. The research tools included standardized parent-child communication style scale (Min,l991), stress coping behaviors scale (Min,1998), and child behavior problems scale (Hun,l996). The data were analyzed using statistical techniques such as Mean, standard deviation, frequency, percentile, t-test, F-test, pearson's correlational analysis, stepwise regression analysis. In the relationship between child perceived parent-child communication style and stress coping behaviors, the children who make open communication with their parents demonstrate high problem-solving, support-seeking coping behavior. The children with closed communication with their parents have high hope expectation, revenge coping behavior. In the relationship between child perceived parent-child communication style and child behavior problem, the children making more closed communication with their parents show more behavior problems. The children with more closed communication with their mothers have more hyperactive behaviors, aggressive behaviors, and immature behaviors, and the children who are making more closed communication retain more anxious behaviors and withdrawn behaviors. In the relationship between child stress coping behaviors and behavior problems, the more problem-solving and support-seeking coping behaviors the children possess, the less problem behaviors they demonstrate. The more hope expectation, revenge coping behavior the children possess, the more problem behaviors they show. With the results above, we can find out that parent-child communication style has an effect on stress coping behavior, and parent-child communication style and stress coping behavior have an influence on child behavior problem.

As the telecommunication market becomes mature in Korea, severe competition has already begun on the market. While service providers struggled for the last couple of years to acquire as many new customers as possible, nowadays they are making more efforts on retaining the current customers. The churn management by analyzing customers' demographic and transactional data becomes one of the key customer retention strategies which most companies pursue. However, the customer data analysis has still remained at the basic level in the industry, even though it has considerable potential as a tool for understanding customer behavior. This paper develops several churn prediction models using data mining techniques such as logistic regression, decision trees, and neural networks. For model-building, real data were used which were collected from one of the major telecommunication companies in Korea. This paper explores various ways of comparing model performance, while the hit ratio was mainly focused in the previous research. The comparison criteria used in this study include gain ratio, Kolmogorov-Smirnov statistics, distribution of the predicted values, and explanation ability. This paper also suggest some guidance for model selection in applying data mining techniques.

The vibration of fuel rods in axial flow is a universally recognized issue within both engineering and academic communities due to its significant importance in ensuring structural safety. This paper aims to thoroughly investigate the stability and nonlinear vibration of a fuel rod subjected to axial flow in a newly designed high temperature gas cooled reactor. Considering the possible presence of thermal expansion and large deformation in practical scenarios, the thermal effect and geometric nonlinearity are modeled using the von Karman equation. By applying Hamilton's principle, we derive the comprehensive governing equation for this fluid-structure interaction system, which incorporates the quadratic nonlinear stiffness. To establish a connection between the fluid and structure aspects, we utilize the Galerkin method to solve the perturbation potential function, while employing mode expansion techniques associated with the structural analysis. Following convergence and validation analyses, we examine the stability of the structure under various conditions in detail, and also investigate the bifurcation behavior concerning the buckling amplitude and flow velocity. The findings from this research enhance the understanding of the underlying physics governing fuel rod behavior in axial flow under severe yet practical conditions, while providing valuable guidance for reactor design.

Background: The objective of behavioral guidance is to establish effective communication that aligns with a child's requirements to manage disruptive behavior. This study aimed to evaluate the effectiveness of the Tell-Show-Do and Ask-Tell-Ask techniques in managing dental anxiety in children during their initial appointment. Methods: The study included 50 children (28 boys and 22 girls) without any prior experience between the ages of 7 and 11 at their first dental visit. The children were randomly categorized into two groups: Group 1, Tell Shows Do, and Group 2, Ask-Tell-Ask. Subsequently, all children underwent noninvasive treatment procedures such as restorations, sealants, and oral prophylaxis. Furthermore, behavioral management techniques were employed based on the allocated group. Finally, anxiety levels for all children were assessed using the Raghavendra, Madhuri, and Sujata Pictorial Scale (RMS-PS) and heart rate at three different intervals (before, during, and after). The obtained data were entered into Microsoft Excel, and statistical analysis was performed using SPSS software. A paired t-test and Mann-Whitney U-test were used to compare the mean and median values of the two groups and determine their effectiveness. Results: Children in the TSD group exhibited statistically significant heart rates and RMS-PS scores in intra-group comparisons. However, children in the ask-tell-ask group showed a significant reduction only in the RMS-PS scores (P < 0.001) but not in the measures used to assess heart rate (P < 0.001). Conclusion: Tell-Show-Do was more effective than ask-tell-ask in alleviating dental anxiety in children. The simultaneous application of these two strategies can synergistically alleviate dental anxiety during a child's initial dentist appointment.

Background: Dental anxiety is a matter of serious concern to pediatric dentists as it may impede the efficient delivery of dental care. If not adequately resolved, a persistent negative response pattern may emerge. Thaumaturgy, commonly known as magic trick, has become popular recently. It is a tool that distracts and relaxes the child by using magic trick while the dentist performs necessary treatment. Hence, the aim of this study was to evaluate the effectiveness of Thaumaturgic aid in alleviation of anxiety in 4-6 - year-old children during administration of local anesthesia using the inferior alveolar nerve block (IANB) technique. Methods: Thirty children aged between 4-6 years with dental anxiety requiring IANB were included in this study. Patients were divided equally into two groups: Group I, thaumaturgic aid group and Group II, conventional non-pharmacological group using randomization. Anxiety was measured before and after using the intervention with Raghavendra Madhuri Sujata-Pictorial scale (RMS-PS), Venham's anxiety rating scale, and pulse rate. All the data were tabulated and compared using statistical analysis. Results: Children in thaumaturgy group (Group- I) exhibited significantly lower anxiety during IANB in comparison with children in the conventional group (Group- II) and the difference was statistically significant. Conclusion: Magic tricks are effective in reducing anxiety among young children during IANB; Moreover, it expands the arsenal of behavior guidance techniques for treatment of children with anxiety and plays an important role in shaping the behavior of a child in pediatric dentistry.
