The fracture of a needle during local anesthesia in dental treatment is rare; however, when it occurs, the needle should be removed without damage to surrounding structures as soon as possible. A fractured needle fragment that is buried in soft tissue would be difficult to remove, and a careful surgical procedure under general anesthesia is recommended in such cases. Children who require dental treatment are often not capable of cooperative behavior, thus unexpected movements can increase the risk of needle fracture. Clinicians can reduce the incidence of needle fracture accidents with a few precautions. In the present case report, we report a case of needle fracture due to abrupt movement during inferior alveolar nerve block anesthesia in a young child, with the purpose of drawing attention to needle fracture incidents. This report describes the possible causes and prevention methods of local anesthetic needle fracture, and the localization methods and surgical procedure for needle fragment removal.

This study analyzed the difficulties elementary school students have in role-playing analogy activities for concept learning of heat transfer. Eleven fifth graders were given an orientation class on role-playing analogy activity, a class for concept learning of heat transfer as presented in a textbook, and then they performed the role-playing analogy activity with concepts of heat transfer. After the classes, researchers investigated the difficulties students encountered through questionnaires and interviews. The following are results of the research: Difficulties that students faced in role-playing analogy activity can be classified into five types. First, students encountered difficulties in expressing the analogy. The students who had difficulties in expressing the analogy focused on expressions outside the science concepts or lacked understanding of the science concepts. They also had difficulties in expressing the analogy because they lacked the expressiveness of analogy or abilities in mapping errors. They had difficulties in expressing the planned role-playing analogy in a narrow space. Second, students also experienced difficulties in performing activities due to lack of understanding on activities or lack of experience. Third, students experienced difficulties in selecting roles because they preferred the specific role or unwanted the specific roles. Fourth, the members of group experienced difficulties in group activities because they did not concentrate on activities, failed to perform roles, or showed attitudes of an onlooker. Fifth, they experienced difficulties in communications due to unilateral communication, conflicts of opinions, and lack of opinions.

Purpose The innovation capability nowadays has become increasingly prominent in the universities not only for schools but also for teachers. However, due to less attention to the knowledge utilization and management, also some objective constraints, which caused the low level of the innovation capacity for our universities teachers under the current development in China. Meanwhile, transactive memory system (TMS) and knowledge sharing are important contents in knowledge management. The combination of both systems will contribute to a much more comprehensive understanding and performance of knowledge management. The purpose of this study is to investigate the structural relationships between TMS, knowledge sharing, and innovation capability among Chinese university teachers' teams, and to propose the practical implication to integrate effectively internal knowledge of the team to improve innovation capability. Design/methodology/approach In order to exam and verify the hypothesis proposed, we developed a questionnaire with 16 survey items, and each item comes with a five-point Likert-type scale. Hyperlink of online questionnaire was shared through WeChat. It's collected 201 responses from 14 universities in China, and the responders are teaching groups' leaders. And all together 191 responses were filtered out as the valid samples. And we analyze the data set and test research hypotheses by using SPSS 22.0 and AMOS 22.0. Findings All hypotheses are supported. The results reveal that knowledge sharing plays an important role in this study as the mediating role. TMS is positively associated with the innovation capability. And the knowledge sharing plays a significant role as mediating value between them, and influences the TMS's effect on innovation capability. It's thus cleared that if our teachers could well communicate, exchange and collaborate with other teachers in the same group, the innovation capability among the teachers would be improved effectively.

In this study, we suggested the design thinking process that was possible to be introduced in science education and also examined the validity of the process in terms of group creativity. To do this, the design thinking process applicable to science education was selected from a variety of design thinking processes developed abroad, and then the process was modified and supplemented. We created the education program based on the developed design thinking process and applied it to high school students. The results revealed that we could offer the design thinking process through the five stages: 'understanding knowledge', 'empathy', 'sharing perspective', 'generating idea', and 'prototype'. With the results of the application of the program, we could confirm the relationship building and information seeking attributes in the understanding knowledge stage and the user-orientation, relationship building, and interpersonal understanding attributes in the empathy stage. We could also find the organization of the team attribute in the sharing perspective stage and the analytical strategic thinking attributes in the generating idea stage. Finally, the communication and analytical strategic thinking attributes in the prototype stage were confirmed. All of the key attributes of the group creativity found from skilled professionals were not confirmed from the students. However, we could ascertain the possibilities that the students should experience the process of group creativity and learn the relevant values through the developed design thinking process.

The selection of a third-party logistics (3PL) provider is a critical process for shippers who want to receive competitive logistics service. However, studies analyzing the factors that influence the selection of 3PL provider from the viewpoint of shippers are insufficient. The present study aims to derive factors to be considered when selecting a 3PL provider by domestic shippers and to present the weights of each factor. The analysis results showed that among the major factors, the "operation factor" showed the highest importance, followed by "strategic factor", and "communication factor". The results of compound weights showed that "cost reduction" is the most important factor, followed by the "expertise of the provider", "inventory management ability", and "human resources management". The present study proposed the core factors that should be considered when selecting a 3PL provider from the shipper's viewpoint. This study also has an industrial implication from the viewpoint of 3PL providers because it provides the basic data for enhancing the shipper's satisfaction by reinforcing the factors that are considered important in by shippers. In future research, it is necessary to classify shippers by industry and analyze the differences in the factors that arise in selecting 3PL companies for each industry.

Purpose: This study was performed to explore the current state of end-of-life (EoL) care education provided to new interns at two university hospitals. Methods: A questionnaire was given to incoming interns (N=64). The levels of acquired knowledge and experience of clinical observation were measured. Seven areas for self-assessment questions were identified and used to analyze the interns' attitudes towards EoL-related education and practice. Results: On average, participants learned five elements (nine in total) from EoL-related classes and two (seven in total) from clinical observation. The most frequently educated element was how to deliver bad news (96.9%) in the classroom setting and how to control physical symptoms (56.5%) in clinical observation. Less than 20% received training on EoL care communication, including discussion of advanced directives. Compared with participants who had no EoL training, those who had EoL training showed positive attitudes in all seven categories regarding overall satisfaction, interest and preparedness in relation to EoL-care classes and practice. Conclusion: Although interns are responsible for caring of dying patients, their EoL training in classroom and clinical settings was very insufficient. Further research should be conducted to establish an education system that provides sufficient knowledge and training on EoL care.

This study is to explore how TV drama describes divorce process by the reason of extramarital relationship in the drama. To explore this subject, 30 drama synopses delineating extramarital relationship were analyzed. The results revealed that most of the couples had difficulties in emotional relationship and communication. The couples relationship was described traditionally patriarchal: husbands showed their authorities and wives showed dependency on their husbands. The partners of extramarital relationship were the lovers before current marriage. The patterns of extramarital relationship included 'intention to look for vitality despite satisfying current marriage' for the husbands and 'intention to avoid dissatisfied current marriage temporally' or 'to maintain marriage despite dissatisfaction' for the wives. For those who married 6 years and longer, more extramarital relationship was accepted as a terminator of the marriage. And in many cases, the divorce dose not mean to maintain the relationship with extramarital partner but to collapse of trust in partner. The results imply that the social work needs to be more sensitive to middle-class couples' communication and relationship problems. This will lead to the development of the social work intervention program for the couples.

The purpose of this study were to develop PBL(problem-based learning) program, and to examine the effects of PBL. This paper applied PBL to a "Culture of Clothing" class, comprised of 23 undergraduate students majoring in Home Economics. As part of the PBL curriculum, the class assigned students to design and create brochures about the culture of clothing by going on field trips to the National Folk Museum of Korea. The class met for five weeks, 3 hours per week. The effectiveness of PBL was measured based on the students' self-reflective journals, self-assessments, and satisfaction surveys. The study gathered three major feedbacks from the students after taking the PBL class. First, the students recognized the importance of cooperation and communication in problem-solving process. Second, the students appreciated that students themselves were implementing the self-directed learning. Third, the students were satisfied with the overall quality of the PBL class, based on their feedbacks and surveys. However, the students' self-assessments show their acknowledgement of the lack of creativity and critical-thinking skills. The study also observed relatively low-satisfaction ratings about the learning environment at the National Folk Museum of Korea.

Start up a company is critical to the regional economy and job creation and so get support from government and other organizations, but there are still exist of high rate of failure and CEO's stressful fear of failure. New firms are of utmost importance for the vitality of national economic driving forces but for those failed firms, they caused social and economic problems directly and indirectly, and brought frustration to the founders. The many education and research programs about entrepreneurship and venture creation were undertaken by the country and organizations, but the education and research about the vigilance of failed to start up company were almost ignored. If the attention can be put into the research about failed companies and the research can make the founders and pre-CEOs aware the failure of establishing a company, that would be very valuable as scenarios to see the company risks. This case study shows the finding the reasons which caused the failure of small venture companies and it's implications in the filed of establishing companies. The technology based venture company which had run 10 years in Daedeok's IT field was selected as the research object. The results show that the important factors such as entrepreneur characteristics(lack of communication and management knowledge), business management(lack of business expertise) and technology(loss of unique feature of product and lack of product extension) were the root cause of failures.

The current curriculum in the 7th informatics, which simply highlights the use of applied programs rather than enhancing creativity through learning several principles in information science and thus making it hard to have optimism on the future as a powerhouse in IT. By diagnosing these problems, Education Ministry revised the existing curriculum to have a more scientific access to the informatics. However, the curricular revision fails to meet the needs of learners sufficiently because it tends to put the considerations of theoretical specialists before the learners them selves. This paper compares and analyzes the overall understanding of learners on informatics, current-curriculum and 7th revised curriculum and that of college-level, thus offering the student-centered one. Also, the research tries to bridge the opinion gap between developer and learner by looking into the understanding level of university majors about the current curriculum. In doing so, thesis may provide the basis on exploring new approaches and contribute to establishing 7th revised curriculum in school.
