Background: Dental phobia or anxiety of patients is the serious impediment to appropriate and effective dental treatment. Sedative technique helps to mitigate patients' fear and anxiety thus make them more cooperative and familiar to dental practices. With increasing attention to sedative dentistry in dentists, educational requirements and technical qualification also become stricter but actual survey on recent sedative dentistry has not been reported yet. Especially there is insufficient study reporting the survey of sedative dentistry subjected to Korean adults. In this paper, we conducted a survey study on the actual condition and practice related to sedation with a questionnaire to dentists in South Korea. Methods: The survey was done for members of The Korean Dental Society of Anesthesiology (KDSA), who had great interest in sedation and for whom survey-by-mail was convenient. 472 members of The KDSA having dental license and solid address and contact information were subjected to the survey by sending them survey questions about their sedative techniques and knowledge. In order to increase the response rate, small gifts were presented to those who accurately responded to the survey questions and text messages and phone calls were made to encourage their participation. We collected their responses over two months and examined the returned surveys. Statistical analysis was performed using IBM SPSS Statistics 21 for each question. Results: Out of 472 dentists, 181 responded (38.4% response rate). 63.0% (114 dentists; 77 male and 37 female) of respondents had experience on sedative technique and their average age was $39.8{\pm}7.6$ year. 74 of them were private practitioners, 17 of them were professors (14.9%), 11 of them were dentists-in-service (9.6%), 11 of them were residents (specialist training) (9.6%) and 1 of them was military doctors (0.9%). There were 89 dentists (78.1%) who were specialists or receiving trainings to be specialist, most of whom were pediatric dentists (55, 48.2%) and oral surgeon (31, 27.2%). The most popular route for drug medications was orderly oral, inhalational, intravenous medication. Combination of oral and inhalational medications or single use of intravenous medication was the most common. The most preferred sedative drug was pocral in oral sedation and midazolam in intravenous sedation. 48.2% of practitioners responded that they experienced side effects and emergency situations. Airway obstruction was the most frequent. Conclusions: Results from the survey show that the protocol and system for sedative dentistry have been improved compared to the past. Nevertheless, quality of emergency protocol, monitoring devices and preparation of sedative drugs was still insufficient to achieve safe sedative procedure. This study acquires novelty since actual survey on recent sedative dentistry for adult patients has not been reported yet.

The purpose of this study is to explore the research trend changes of convergence education since 2011 compared to the convergence education research that has been steadily continuing in science education. The trend in convergence education were investigated by comparing the number of publications, research subjects, research content, and topic linkages with previous studies, and using the network analysis method to check recent research trends. In the field of science education, the number of papers related to convergence education has been published more than 8.0% steadily, and it has been increasing since 2012, then decreasing again from 2015 and gradually increasing again from 2017. The subjects of study were high in elementary school students, while those in middle school, high school, and university students were low. While the number of in-service teachers increased, the number of pre-service teachers decreased, and the literature and public increased somewhat. In study content, effectiveness studies decreased, while development studies increased, and theoretical and perception studies appeared similar. In thematic linkage, the intra-science linkage was 23.9%, and the extra-science linkage was 76.1% and engineering/technology and art were high in extra-science linkage. In network analysis, elementary, science, STEAM, and program words have a high frequency of appearance and appear together with other words to lead the network. The educational implications of the research trend of convergence education will be more emphasized in the field of science education in the future, and in order to take root in the education field, research on secondary students should be more actively studied. In addition, it is necessary to move away from research on STEAM-centered program development and effects, and to increase research to establish the philosophical basis and theoretical of convergence education.
The purpose of this study is to determine whether using a dietary education program based on learning cycle model has any significant effect on enhancing their nutrition knowledge, dietary behavior, science-process skill and scientific attitude. The subjects of this study were children in H and G daycare center in G City. The experiment group of this study was 16 children in the class of five-year-olds and 7 children in the class of four-year-olds who passed their birthday and became five-year-olds in H daycare center. The Analysis of Covariance(ANCOVA) and Pared t-test was conducted using SPSS WINDOWS 20.0 program. The results of applying dietary education program were as follows. Experimental group indicated enhancements between pre and post test of Nutrition Achievement Test, Nutrition Quotient for Preschooler, Science Process Skill and Scientific Attitude Assessment compare to comparative group. Therefore, we can conclude that the dietary education program does have effects on enhancing of nutrition knowledge, dietary behavior, science process skill and scientific attitude. The result of this study can be used as basic data to study dietary related factors that present importance of health dietary life of young children and need to provide educational experience of healthy diet for young children.

The positive impacts of robotics education and programming education on learners are similar. However, robotics education differs from programming education because it includes purchasing and building robots that cause financial and cognitive load of learners. Due to these differences, two kinds of education may not possess equal efficacies for all schools or all learning objectives. To verify this hypothesis, we conducted meta-analysis of studies on robotics education published in South Korea to estimate the effect sizes and compare it to that of programming education. The difference between the average effect sizes of robotics education and of programming education was significant, as the former was 0.4060 and the latter 0.6664. The average effect size of programming education was significantly larger than that of robotics education for primary school students. Middle school students achieved the highest results in both robotics education and programming education. Also, robotics education became more effective than programming education as students were older. Analysis on objectives showed that programming education uniformly affected all areas, whereas robotics education had more impact on affective domain than cognitive domain. Robot construction had the largest effect size, followed by robot construction and programming, robot programming, and robot utilization. Programming education has larger positive impacts on students overall compared to robotics education. Robotics education is more effective to upperclassmen than programming education, and improves affective domain of students. Also, robotics education shows higher efficacy when combined with various subjects.
The importance of small group activity has recently been emphasized in the gifted education in science because of the increased needs to foster the human resources that could explore through the communication and collaboration. In this study, we investigated the characteristics of the verbal interaction according to the learning styles of the gifted-students in science in the small group activity and examined how learning style affected the interaction within a group in order to seek an effective grouping strategy. The competition, cooperative, and dependent students with learning style in the small group 1 and the cooperative, cooperative, dependent students in the small group 2 were assigned by the 6 science high school students. The analyses of the results revealed that the small group 1 showed the asymmetric interaction of the low level, whereas the small group 2 showed the symmetric interaction of the high level. In other words, the frequencies of in-depth interaction in the small group 2 were higher than those in the small group 1, and also students in the small group 2 were equally involved in the activity rather than the small group 1. These results suggested that the grouping by the students' learning styles in the small group activity should affect significantly the participation decision in activity and the level of verbal interaction. Educational implications of theses findings were discussed.
Korea's film industry structure is focused on commercial movies centering on large companies, and its diversity and artistry are relatively overlooked. In addition to trends in the digital media age, the flood of consumable contents on the basis of special effects such as C.G, And is losing popularity as a popular art. The popular art should lead the mature social culture with the educational enlightenment character which induces the indirect experience and the wide insight of the world through the material and expression about the humanities study of the individual and the society. The analysis of the society's artistry and artistry about the movie "(2017)" can be a measure of the definition and kind of artistry in commercial movies and methodology about the manifestation of artistry. As a research methodology, we try to measure the future of the film industry by analyzing the status of the film as popular art, such as intellectual exploration and logical completeness of the essence of society, Through analyzing and criticizing the artistic characteristics in commercial films, I would like to suggest some improvement points by deriving the indicators of the artistic nature of commercial films. The film "1987" is a good example of an ideal commercial film with an artistry that cultivates cultural literacy, promotes civic consciousness through enlightenment messages, and plays a role of self-reflection through art experience. In other words, it shows the possibilities of commercial film with artistry in popular culture, such as a humanistic examination of true history and society, and an introspective gaze of the director expressed through the film society.

In this study, two types of Au/TiW bump samples were fabricated by the electroplating process onto Al/Si and SiN/Si wafers for the COG (Chip On Glass) packaging. TiW was used as the UBM (Under Bump Metallurgy) material of the Au bump and it was deposited by a sputtering method under the sputtering powers ranges from 500 to 5000 Watt. We investigated the delamination phenomenas for the prepared samples as a function of the input sputtering powers. The stable interfacial adhesion condition was found to be 1500 Watt in sputtering power. In addition, the SAICAS (Surface And Interfacial Cutting Analysis System) measurement was used to find the adhesion strength of Au bumps for the prepared samples. TiW UBM films were deposited at the 1500 Watt sputtering power. As a results, there was a similar adhesion strengths between TiW/Au interfacial films on Al/Si and SiN/Si wafers. However, the adhesion strength of TiW UBM sputtering films on Al and SiN under films were 2.2 times differences, indicating 0.475 kN/m for Al/Si wafer and 0.093 kN/m for SiN/Si wafer, respectively.

Objectives : The purpose of the study was to evaluate the related factors of depression in mothers bringing their offspring for evaluation or treatment of problematic behaviors. Methods : Fifty mothers were recruited through their offspring's evaluation or treatment for offspring's problematic behaviors. Psychological tests battery including Korean Wechsler Adult Intelligence Scale and the Korean Educational Development Institute-Wechsler Intelligence Scale for Children was administered to all mothers and their offspring. Mothers completed Korean version of Child Behavior Checklist (K-CBCL), and teachers completed Teacher's Report Form (TRF). On the basis of the maternal depression, the mothers were divided into two groups. Results : 1) Among the fifty mothers, $42\%$ of the mothers had depressive disorder, $16\%$ had anxiety disorder, and $42\%$ had no psychiatric disorder. 2) Depressed mothers rated significantly higher in aggressive behaviors, externalizing problems of K-CBCL in their children. 3) Children of depressed mothers had lower score in picture arrangement and coding subtests of KEDI-WISC than those of no psychiatric disorder mothers. 4) After controlling for the total problematic behavior scores of TRF, mother's depression is positively correlated with aggressive behaviors, externalizing problems, total problematic behaviors of K-CBCL, and negatively correlated with coding of KEDI-WISC. Conclusion : Children's aggressive behavior, externalizing behavior, total problematic behaviors and low coding score may be associated with mother's depression.
The purpose of this study was to find factors affecting the psychological well-being of married working women in Seoul. For this purpose, survey data form 332 employed married women residing in Seoul are used to evaluate the relative effects of Psychological well-being of married working women. Survey questions included demographic information, housework and child-rearing related variables, work related variables, variables related with social support systems, items on child care services for the preschoolers, and psychological well-being of married working women. The major findings were as follows: 1) The psychological well-being of married working women score is 36.14(mean score is 32). The difference between the psychological well-being of married working women varied this according to socio-demographic variables: educational level, income level, spouse's support, occupation, and job satisfaction. 2) The factors that affected psychological well-bing were amount of household labor by husband, job satisfaction, socio-support systems, and educare service satisfaction. 3) The factor that had the most significant impact on the psychological well-being of married working women is job satisfaction. It is suggested to utilize the Employment Assistant Program to establish friendly working environment for married women.
The main purposes of this study were to analyze the moderating effect of parenting knowledge in the relationship between socio-demographic factors and parenting style. This study was conducted with the data from 'Panel Study Korean Children(2009).' Among the original data, a sample of 1,637 mothers with infants ranged from 13 to 18 months old was selected. The results of this study were as follows. First, there were significant differences in child's birth-order, mother's education level, and monthly family income. Second, there was a statistically significant difference in the parenting style of mothers in their parenting knowledge. That is, the mother with a high score in parenting knowledge reported more positive parenting style. Lastly, the interaction effects between socio-demographic variables and parenting knowledge on parenting style were statistically significant only with the variables such as child's birth-order and mother's education level. The mothers who cared for their first child and got a high score in parenting knowledge showed the most desirable parenting style, and the mothers whose educational level was under high school graduation and parenting knowledge score was low reported the lowest score in parenting style. These results suggest parenting knowledge should be subject-specifically provided as the differences in socio-demographic variables.
