A Study on Usage Behavior of Influencers by College Students
Sanghee Park(Sanghee Park),Kiyoon Kim(Kiyoon Kim) J-INSTITUTE 2022 Public Value Vol.7 No.2
Purpose: This study aims to explore the various influencing factors that influencer channel characteristics have on users, targeting university students who are the main users of various social media after the pandemic. Method: in-depth interviews were conducted with 15 college students to investigate their influencer usage behaviors, explore factors affecting their use, and develop a related research model. Results: First of all, in the early days of using content, they encountered content for reasons such as topicality, information, friend recommendation, and curiosity, and there was a tendency to select content based on similar tastes through algorithm and friend recommendation. In particular, the highly topical contents of influencers recommended by friends played an important role in forming peer culture with friends. It was found that sincerity and candor revealed in the content were important factors influencing the period when an influencer's channel was subscribed and used continuously and intimacy was formed. When they felt their sincerity and honesty, they realized that they were different from other influencers and continued to watch them. It was found that the interaction factor plays a decisive role in forming intimacy with influencers and contin-uously using the channel for more than 3 months, forming a fandom and recommending content to others. Conclusion: This usage behavior of college students has great implications for companies that want to pro-mote and market through the influencer channel. As the factors that affect users vary depending on when they use the influencer channel, a promotional strategy that reflects this is needed. In addition, as integrity and hon-esty are important factors in building users' trust, it should be given more important value than anything else in maintaining and managing channels.

Purpose: Kyungpook National University School of Medicine has been implementing hybrid problem-based learning (PBL) since 1999. The aim of this study was to investigate the changes in the students’ perceptions and satisfaction levels of hybrid PBL. Methods: The target period of our study was from 1999 to 2014, and target subjects were second-year medical students in Kyungpook National University School of Medicine. The survey was conducted at the end of semester. We had a focused interview with group leaders and some volunteer students. Results: As for the scores regarding students’ overall satisfaction with PBL, there was significant improvement in 2005 compared to 2002, but the scores decreased and no differences between the survey years noted after 2005. The students’ preference ratio for the once a week PBL sessions, tutor presence, synchronization of contents, and arrangement of PBL sessions and related lectures was 60%–80%, 50%–90%, 52%–96%, and 78%–93%, respectively. Conclusion: In order to increase students’ satisfaction with hybrid PBL and to improve the perception of it, firstly, it is necessary to arrange the date and the time of PBL sessions so that students can concentrate on PBL. Secondly, PBL cases should be selected and arranged to be well synchronized with the ongoing lectures. Finally, it is important to create a safe atmosphere so that students can engage actively in PBL sessions.

Purpose: The purposes of this study were to analyze the course outcomes of integrated courses of a medical school that introduced an outcome-based curriculum and to suggest ways to improve techniques in the description of outcomes. Methods: In order to investigate the course outcomes of 39 courses in the first and second grades at Kyungpook National University School of Medicine in Korea, verbs for the course outcome were classified according to Bloom’s taxonomy and frequency analysis was completed. The appropriateness of use of verbs in description of the outcomes was also analyzed. Results: The total number of course outcomes for both grades was 497. The number of course outcomes per credit ranged from a minimum of 0.9 to a maximum of 22.0. Most of the course outcomes were classified as the comprehension domain according to Bloom’s taxonomy. The most frequently used verb was “explain,” accounting for 61.0% (n=303) of the entire course outcome verbs. Some verbs in the outcomes, however, were unmeasurable. Conclusion: The major findings of this study include the followings. First, the number of course outcomes varied according to courses. Second, several course outcomes included unmeasurable verbs. Finally, most of the verbs used to describe course outcome belonged to the two lower levels of Bloom’s taxonomy—knowledge and comprehension. In order to improve the description of course outcomes, this study suggests that it is necessary to adjust the number of course outcomes, applicate overt behavior verbs, and elevate the level of course outcomes from the lower memorizing level to the higher application level.

Objective: This study was performed to investigate the alveolar bone of lower incisors in skeletal Class III adults of different vertical facial patterns and to compare it with that of Class I adults using cone-beam computed tomography (CBCT) images. Methods: CBCT images of 90 skeletal Class III and 29 Class I patients were evaluated. Class III subjects were divided by mandibular plane angle: high (SN-MP 〉 38.0°), normal (30.0° 〈 SN-MP 〈 37.0°), and low (SN- MP 〈 28.0°) groups. Buccolingual alveolar bone thickness was measured using CBCT images of mandibular incisors at alveolar crest and 3, 6, and 9 mm apical levels. Linear mixed model, Bonferroni post-hoc test, and Pearson correlation analysis were used for statistical significance. Results: Buccolingual alveolar bone in Class III high, normal and low angle subjects was not significantly different at alveolar crest and 3 mm apical level while lingual bone was thicker at 6 and 9 mm apical levels than on buccal side. Class III high angle group had thinner alveolar bone at all levels except at buccal alveolar crest and 9 mm apical level on lingual side compared to the Class I group. Class III high angle group showed thinner alveolar bone than the Class III normal or low angle groups in most regions. Mandibular plane angle showed negative correlations with mandibular anterior alveolar bone thickness. Conclusions: Skeletal Class III subjects with high mandibular plane angles showed thinner mandibular alveolar bone in most areas compared to normal or low angle subjects. Mandibular plane angle was negatively correlated with buccolingual alveolar bone thickness.
Atypical Cellular Chorangioma: a rare case and review
( Sanghee Lee ),( Hee Jeong Lee ),( Hae Nam Lee ),( Min Jeong Kim ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-
Chorangioma of placenta is a benign and common tumor of the placenta composed of blood vessels in 0.5-1% of all pregnancies. Most chorangiomas are small and do not produce any symptom. But a tumour> 4 cm in size is called a giant chorioangioma and associated with maternal, fetal and neonatal complications. The maternal complications include preeclampsia, polyhydramnios, fetal growth restriction, fetal anemia, cardiomegaly and an increasing the risk of preterm labour and placental abruption. Atypical cellular chorangioma is mitotically active tumor with focal necrosis, exhibiting histologic features of a sarcoma. Some authors have suggested that these occasional chorangiomas require evaluation of malignancy. We describe an unusual chorangioma with high cellularity and abundant mitosis that, after careful examination and postpartum follow-up in 30years-old primiparous women (31 gestational weeks with PPROM). Also the careful ultrasonographic examination was also important in prediction palcenta disease.
Implementation of problem-based learning in medical education in Korea
Sanghee Yeo,Bong Hyun Chang 한국의학교육학회 2017 Korean journal of medical education Vol.29 No.4
Purpose: This study aims to identify how problem-based learning (PBL) has been implemented in Korean medical education, and how it is evaluated by each medical school. Methods: For this study, a total of 40 medical schools in Korea were surveyed via e-mail. The survey tool was a questionnaire consisting of 22 questions which was developed independently by the researchers. Results: Of the 40 medical schools, 35 schools were implementing PBL programs in their medical curriculum, while five were found not currently to be running the program. A large number of the schools which introduced PBL (30 schools, 85.7%) used a hybrid PBL model. In over 70% of the medical schools surveyed, professors evaluated the effects of PBL as positive. Most medical schools (85.7%) stated they would maintain or expand their use of PBL. However, the lack of understanding and skeptical attitude of the faculty on PBL, the lack of self-study time and passive attitude of students, insufficiency of good PBL cases, and the perfunctory PBL introduction for school accreditation interfere with the successful PBL. Conclusion: PBL has been incorporated in Korean medical curriculum as hybrid PBL type. It is analyzed that intensive tutor training and good PBL case development are necessary for the success and effective operation of PBL.
