The purpose of this study is to investigate the relationship of Social Presence, Flow, Satisfaction, and Information Sharing Intention among YouTube Travel Content Users. A total of 360 questionnaires were used as the final analysis data using SPSS 29.0 statistical program. The validity of the hypothesis was tested by multiple regression analysis and the results are as follows. First, there were positively significant correlations between Social Presence among YouTube Travel Content Users. and Flow. Second Social Presence among YouTube Travel Content Users was significantly and positively correlated with Satisfaction. Third flow had a significantly positive effect on satisfaction. Fourth there were positively significant correlations between Satisfaction and Information Sharing Intention Based on the results of this study the implication is as follows. This study aims to raise awareness of the importance of using YouTube for tourism content and to examine the impact of social presence on YouTube travel content user's flow, satisfaction, and intention to share information, in order to provide foundational data for planning, producing, and marketing tourism content and contribute to the development of tourism studies in the future. In addition, this study seeks to motivate the development of new business models for sustainable tourism industry development and to increase understanding of user attitudes, thereby providing assistance in the production of travel media content and other related areas. 본 연구의 목적은 유튜브 여행콘텐츠 이용자의 사회적 실재감이 몰입, 만족, 정보 공유의도에 미치는 영향을 고찰하는 것이다. 연구의 표본은 편의 추출법(convenience sampling)을 이용하여 유튜브 여행콘텐츠를 시청해 본 적이 있는 성인 이용자를 대상으로 총 360부의 설문을 최종 분석 자료로 활용하였으며, 자료는 SPSS 29 통계프로그램을 사용하여 빈도분석, 탐색적 요인분석, 신뢰도 분석, 상관관계분석과 회귀분석을 실시하였으며 다음과 같은 결과를 도출하였다. 첫째, 유튜브 여행콘텐츠 이용자의 사회적 실재감은 몰입에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 유튜브 여행콘텐츠 이용자의 사회적 실재감은 만족에 유의한 정(+)의 영향을 미쳤다. 셋째. 몰입은 만족에 유의한 정(+)의 영향을 미쳤다. 넷째, 만족은 정보공유 의도에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 위와 같은 결론을 바탕으로 본 연구는 유튜브를 활용한 관광콘텐츠의 중요성을 인식하게 하고, 유튜브 여행콘텐츠 이용자의 사회적 실재감이 몰입, 만족, 정보 공유의도에 미치는 영향을 고찰하여 관광콘텐츠 기획, 제작 및 마케팅 활용을 위한 기초자료를 제공하여 향후 관광산업의 실질적인 발전에 이바지하고자 한다. 또한, 지속가능한 관광산업의 발전을 위해 새로운 비즈니스 모델을 제시하는데 동기부여가 되고, 이용자들의 태도에 대한 이해를 높이는 데 도움을 주어 유튜브 등의 여행관련 미디어 콘텐츠 제작 등에 도움이 되고자 한다.
Channel Protection Layer Effect on the Performance of Oxide TFTs

We have investigated the channel protection layer (PL) effect on the performance of an oxide thin film transistor (TFT) with a staggered top gate ZnO TFT and Al-doped zinc tin oxide (AZTO) TFT. Deposition of an ultra-thin PL on oxide semiconductor films enables TFTs to behave well by protecting the channel from a photo-resist (PR) stripper which removes the depleted surface of the active layer and increases the carrier amount in the channel. In addition, adopting a PL prevents channel contamination from the organic PR and results in high mobility and small subthreshold swings. The PL process plays a critical role in the performance of oxide TFTs. When a plasma process is introduced on the surface of an active layer during the PL process, and as the plasma power is increased, the TFT characteristics degrade, resulting in lower mobility and higher threshold voltage. Therefore, it is very important to form an interface using a minimized plasma process.

Background: The frequent and distressing adverse events (AEs) of postoperative nausea and vomiting (PONV) are of major concern in 63-84% of adult patients undergoing thyroidectomy. We conducted this prospective study to compare two prophylactic strategies; sevoflurane combined with ramosetron and propofol-based total intravenous anesthesia in a homogenous group of non-smoking women undergoing total thyroidectomy. Methods: In the current prospective study, we enrolled a consecutive series of 64 female patients aged between 20 and 65 years with an American Society of Anesthesiologists physical status of I or II who were scheduled to undergo elective total thyroidectomy under general anesthesia. Patients were randomized to either the SR (sevoflurane and remifentanil) group or the TIVA group. We evaluated the incidence and severity of PONV, the use of rescue anti-emetics and the severity of pain during the first 24 h after surgery. Results: There were no significant differences in the proportion of the patients with a complete response and the Rhodes index, including the occurrence score, distress score and experience score, between the two groups. In addition, there were no significant differences in the proportion of the patients who were in need of rescue anti-emetics or analgesics and the VAS scores between the two groups. Conclusions: In conclusion, TIVA and ramosetron prophylaxis reduced the expected incidence of PONV in women undergoing total thyroidectomy. In addition, there was no significant difference in the efficacy during the first 24 h postoperatively between the two prophylactic regimens.

Pediatric hypertensive crisis is a potentially life threatening medical emergency, usually secondary to an underlying disease. Hypertension commonly occurs during general anesthesia, and is usually promptly and appropriately treated by anesthesiologists. However in children with severe, unexplained, or refractory hypertension, it has the potential to cause morbidity and even mortality in susceptible patients. We report an anesthetic management of an unexpected hypertensive crisis that developed during general anesthesia in a three-year-old girl with undiagnosed severe left renal artery stenosis.

Background: As the number of elder patients grows, spinal anesthesia for such patients are increasing significantly. Any effort is needed to use the least anesthetic drug for maintaining the anesthesia while avoiding hazards of cardio-pulmonary complications. Methods: American Society of Anesthesiologists physical status classification I and II, Forty five elderly patients (≥ 60 years) who received transurethral resection of the prostate or transurethral resection of the bladder tumor were allocated randomly into three treatment groups. The DMT 0.5 group was designed as with dexmedetomidine 0.5 μg/kg while the DMT 1.0 group has a 1 μg/kg intravenous injection over 10 min before anesthetic induction. The Control group was designed to get a normal saline. Each group was compared regarding the maximum sensory block level, extension of anesthesia, degree of motor block, level of sedation, VAS score and complications. Results: There were no significant differences among the 3 treatment groups regarding the maximum level of sensory block and motor block. However, the duration of sensory block was significantly longer in DMT 1.0 group than in the control group (P = 0.045). Both DMT 1.0 group (median = 3, range = 2-6) and DMT 0.5 group (median = 3, range = 1-6) showed a mean value of 3-4 Ramsay sedation score, which resulted in more excessive sedation and significantly greater incidence of bradycardia compared to the control group. No complications such as hypotension, nausea, tremor, and hypoxia were found during this investigation. Conclusions: In elder patients, the DMT 1.0 group is effective in duration of sensory block and is superior in the aspect of prolonged duration of sensory block compared to the DMT 0.5 group.
