        日本語教育ならびに日本語習得研究におけるSNSの活用

        松下由美子(Matsushita, Yumiko),西花?子(Nishihana, Keiko),坂本正(Sakamoto, Tadashi) 한국일본문화학회 2018 日本文化學報 Vol.0 No.77

        This paper discusses the potential and challenges of using SNS in Japanese language education and Japanese language acquisition research. Along with the rapid spread of Internet usage, the Japanese language education field has been undergoing a rapid retrenchment. Against this background, this paper sets out to review and evaluate past research on SNS as well as to analyze the results of a questionnaire given to Japanese language learners at two Korean Universities concerning their awareness and usage of SNS and how it meets learner’s needs. The written questionnaire results show that over 80% of Japanese learners answered “yes” to the question of whether they want to use SNS in their learning. The results also show that a larger number of learners would like the possibility of communicating directly with Japanese speakers two or three times per week, for about thirty minutes each time. Moreover, SNS can be used in Japanese language acquisition research, allowing for communication with remote subjects. By using ZOOM, not only can messages and conversations be recorded and analyzed, the analysis of non-verbal communication is also possible Furthermore, SNS can be used not only for quantitative but also qualitative research, since our ability to make comments while viewing a file allows us to analyze internal processes. However, there are still many questions to consider, including not only how best to meet learners’ needs, but also how to reduce the emotional burden of learners when they face native Japanese speakers, how to prevent information disclosure, and the role of teachers’ networks. These are all issues that still need to be addressed.

        Sedative methods used during extraction of wisdom teeth in patients with a high level of dental anxiety

        Mika Seto,Haruhiko Furuta,Yumiko Sakamoto,Toshihiro Kikuta 대한구강악안면외과학회 2011 대한구강악안면외과학회지 Vol.37 No.3

        Introduction: Intravenous sedation is performed to ensure smooth and safe surgery. Dental anxiety is a reaction to an unknown danger. The Spielberger’s state-trait anxiety inventory (STAI) can be used to simultaneously evaluate the levels of state and trait anxiety. State anxiety is defined as subjective feelings of nervousness. This study assessed the presurgical anxiety using STAI and performed intravenous sedation for patients whose level of state anxiety was > stage IV. Based on our clinical experience, it is believed that higher doses of sedatives are needed to induce the desired levels of sedation in patients with a high level of state anxiety. Objectives: This study examined whether the sedative consumption of the patient with a high anxiety level increased. Patients and Methods: Patients with state anxiety scores of ≥51 were included in Group V, and those with state anxiety scores ranging from 42 to 50 were placed in Group IV. To induce sedation, intravenous access was established, and a bolus dose of 3.0 mg midazolam was administered intravenously. Sedation was maintained by administering a continuous infusion of propofol, which was aimed at achieving an Observer’s Assessment of Alertness/Sedation scale of 10-12/20. In this study, midazolam was initially administered when the body movements appeared to occur or the blood pressure increased. This was followed by the administration of higher doses of propofol if low sedation was observed. Results: There were no significant differences in the patient demographics, duration of sedation, and doses of local anaesthetic agents between Groups IV and V. The midazolam dose and mean propofol dose needed to maintain comparable levels of sedation were significantly higher in Group V than in Group IV. Conclusion: In female patients, whose level of preoperative state anxiety is more than Stage V of STAI, a large quantity of sedatives is needed for intravenous sedation.

        SNS利用で会話能力が伸びるのか - Can Do Statements と交流後の意識調査を基にして-

        西花?子(Nishihana, Keiko),松下由美子(Matsushita, Yumiko),坂本正(Sakamoto, Tadashi) 한국일본문화학회 2019 日本文化學報 Vol.0 No.81

        This paper addresses the improvement of oral proficiency in Korean learners of the Japanese language who engaged in interactions with Japanese native speakers based on the results of a survey. Twenty-two pairs of Japanese and Korean students interacted on social media through video- or voice-calls. Before and after these interactions, the Korean students were asked to fill out a survey using “Can-Do” Statements. The group of students who engaged in the social media interactions were then compared with a group of nonparticipant learners of Japanese, and no differences were found in Japanese language acquisition between the two groups in this one-and-a-half month study. However, the results of the survey demonstrate that the learners who engaged in the interaction were satisfied with the experience. Their comments included statements such as, “I feel that my conversational skills have improved,” “I feel more confident about how I use Japanese,” and “I understood the conversation better, because we used video-calls instead of text messages.” Six months later, an additional survey was conducted in Korean and the comments obtained from it were as follows: “I want to talk with more Japanese people,” “I have become conscious about grammar and words I have not learnt yet,” and “I started checking the dictionary more often.” The participants also indicated that managing interactions out of the classroom, the choice of the social media used, and matching conversation partners were potential ways to improve the social media experience.
