As the rate of foreign workers increasing, the rates of their children are rising, as well. The children's native countries vary from Japan, China to Indonesia, and difficulty of learning is expected in their entering the regular education due to the differences in the contents and curriculum they had learnt. This study analyzed the science textbooks of five Asian elementary schools including Korea, China, Indonesia, Thailand, and Iran-in diversified sides focusing on the content of earth science, for the children of foreign workers. The characteristics of the elementary science textbooks of the subject countries were compared in seven criteria-the rate of earth science in the textbooks, how units are arranged, whether the earth science contents are included, the contents highly related to their socio-cultural traits, photographs, scientific inquiries, and test items. The textbooks showed numerous differences with their own characteristics, and it is expected that the children of foreign workers would face difficulties in studies taking parts in the Korean formal education. Hereupon, this study proposes the needs of development of sub-materials for the children of foreign workers adapting to schools, and reinforcement of educating teachers for understanding children, with a national plan for the children excluded from education due to problems such as an illegal residence.

Purpose: The purpose of this study was to investigate the influence of nursing students' self-reflection and insight, and academic selfefficacy on their clinical reasoning competence. Methods: Data were collected from 147 third- and fourth-year nursing students who had more than 6 months of clinical training experience. Clinical reasoning competence, self-reflection and insight, and academic self-efficacy were measured using self-reported questionnaires. Data analysis was conducted with IBM SPSS 25.0 using one-way ANOVA, independent t-test, Pearson correlation coefficient, and multiple regression analysis. Results: Clinical reasoning competence was positively correlated with self-reflection and insight (r=.24, p=.003) and academic self-efficacy (r=.30, p<.001). Academic self-efficacy (β=.23, p=.011), dissatisfaction with major (β=-.17, p=.034), and 5~8 case studies (β=-.39, p=.027) were identified as factors influencing clinical reasoning competence (adjusted R²=.15). Conclusion: To improve the clinical reasoning competence of nursing students, it is necessary to develop the academic self-efficacy of complex cases and provide critical inquiries, debriefing tailored to clinical reasoning, and sufficient reflection during clinical and simulation practice.

Purpose: This study was conducted to develop and evaluate a Web-based program for the maternal role of primiparas who use the internet. Method: The study process was a systems requirements analysis, design and development of a program, program testing by experts, program implementation, and program evaluation by users. A nonequivalent control group non-synchronized design was used. The data was collected from October 5th, 2002 to February 24th, 2003. Result: 1. Based on inquiries into mothers' needs, a Web-based support program was developed. The program was then modified from feedback received from experts. 2. In a sub-scale analysis of mothers' perception of a baby, amenability and persistence was significantly higher in the intervention group. The differences in the mean score of maternal self-confidence and maternal satisfaction were significant. 3. Cyber counseling was done for a total of 73 cases and the most frequent problems for counseling were feeding and nutrition (28.8%), followed by baby care, and health problems. Conclusion: It was proven that a Web-based support program provided appropriate support to primiparas and was effective in promoting their maternal role. Therefore, this study suggests that a Web-based support program for primiparas can become a powerful nursing intervention on virtually all mother and infant health concerns.

In this study, we developed a chatbot (Dialogue agent) using small Q & A data and evaluated its performance. The chatbot developed in this study was developed in the form of an FAQ chatbot that responds promptly to customer inquiries. The development of chatbot was conducted in three stages : 1. Analysis and planning, 2. Content creation, 3. API and messenger interworking. During the analysis and planning phase, we gathered and analyzed the question data of the customers and extracted the topics and details of the customers' questions. In the content creation stage, we created scenarios for each topic and sub-items, and then filled out specific answers in consultation with business owners. API and messenger interworking is KakaoTalk. The performance of the chatbot was measured by the quantitative indicators such as the accuracy that the chatbot grasped the inquiry of the customer and correctly answered, and then the questionnaire survey was conducted on the chatbot users. As a result of the survey, it was found that the chatbot not only provided useful information to the users but positively influenced the image of the pension. This study shows that it is possible to develop chatbots by using easily obtainable data and commercial API regardless of the size of business. It also implies that we have verified the validity of the development process by verifying the performance of developed chatbots as well as an explicit process of developing FAQ chatbots.

Research into scientific inquiry methods indicates that providing various types of inquiry methods can enhance students' science loaming in terms of providing students with actual science in various ways' more so than exposure to one type of inquiry method. This article develops a framework for an analysis of scientific inquiry types based on the nature of scientific enterprise. We selected three types of scientific inquiry: these were minds-on activities, hands-on activities, and experimenting. Elementary science textbooks in the 7th national science curriculum were analysed according to the following subject areas; earth science, physics, biology, and chemistry. A total of 61 teaching units from 3rd through 6th grade science textbooks were investigated. The frequencies of each type of scientific inquiry method were slightly different among four science subject areas. The most frequent type which appeared in physics and chemistry was the hands-on type, while the minds-on activity type was the most frequent type which appeared in earth science and biology.

The purpose of this study was to describe the elementary teachers' teaching behavior procedure in verification-type laboratory instructions. In order to do this, we should know first what constituted the teaching behavior elements in the teachers' instructions, before the teaching behavior can be analyzed. Thirty sets of instructions were recorded and their transcripts were used in this study. The results of this study indicated that the number of teaching behaviors numbered twenty four in total, and that the teaching behaviors could be classified into nine categories, and finally the procedure used in verification-type laboratory instructions generally followed seven steps. These steps can be described as follows; reminding subjects of the preliminary learned concept, presenting inquiry type questions or introducing the main concept, explaining the method used or presenting the predictable outcome/matter for verification, performing lab-based activities, presenting the outcomes, applying the main concept, and finally closing the instruction. For the purpose of promoting more authentic scientific inquiries using these types of instructions, the authors's claims were discussed.

Dental local anesthesia is performed daily on a global scale. Adverse effects are rare, but the topic of neurotoxicity of local anesthetics deserves to be explored, as publications can be controversial and confusing. Therefore, a need was felt to address and question the evidence for potential neurotoxicity of dental local anesthetics. This review aimed to assess the studies published on the neurotoxicity of dental local anesthetics. A Pubmed^Ⓡ search was conducted between January 2019 and August 2019. This revealed 2802 hits on the topic of neurotoxicity or cytotoxicity of the following anesthetics: lidocaine, prilocaine, mepivacaine, articaine, ropivacaine, and bupivacaine. Only 23 papers were deemed eligible for this review: 17 in vitro studies, 3 reviews and 3 audits of national inquiries. The heterogeneous literature on this topic showed that all dental local anesthetics are potentially neurotoxic in a concentration and/or exposure time fashion. There seems no consensus about what cell lines are to be used to investigate the neurotoxicity of local anesthetics, which makes the comparison between studies difficult and ambiguous. However, the bottom line is that all dental local anesthetics have a neurotoxic potential, but that there is no unanimity in the publications about which local anesthetic is the least or the most neurotoxic.

This study analyzes on conjecturing tasks in elementary mathematics textbook. We adopted Peircean semiotic perspective and variation theory to analyze conjecturing tasks in elementary mathematics textbook. We specifically analyzed mathematical tasks designed to support students' inquiries into definitions and properties of quardrilaterals. As a result, we found that conjecturing tasks in textbooks do not focus on supporting students' diagrammatic reasoning and inductive verification on provisional abductions. These tasks were mainly designed to support students' conjecturing on commonalities of mathematical objects rather than differences between objects.

Currently, majority small ship's clutch for power transmission to propeller relies on multi plate hydraulic clutch regardless its size. Most of the small ships do not have a spare equipments of clutch. Furthermore, many ship engineers do not have an ability as well as enough experience to solve this problem related to the hydraulic clutch during the voyage. Therefore, any small problems cause many serious marine accidents. Once the clutch has problem, almost of all ships can not sail by itself anymore and it must be towed by salvage boat, maritime police ships, or fish guidance boat etc. In this case, all the accidents will be categorized as a marine accident and they all need to go through marine accident court inquiries. In this study, an understanding of each crew on hydraulic clutch system has been profoundly measured. Furthermore, the knowledge on an emergency navigation protocol of each crew has been also profoundly checked. Additionally, various surveys on hydraulic clutch classes has been performed and its satisfaction of crews on this topic have been carefully checked based on various feedback from students who took these courses. All of the above data from this study will be used to reduce marine accidents in current marine industry.
