Despite current regulations requiring social distancing due to coronavirus disease 2019, problem-based learning (PBL) requires student interaction to achieve common goals and enhance critical thinking and deep learning abilities. Social presence in the online education environment reduces both perceptions of physical distance and psychological distance in interactions. This study aimed to compare PBL activities between in-person and videoconferencing classes, and to investigate social presence and learning satisfaction in a videoconferencing PBL environment. The PBL consisted of six modules for both the first and second years of Chonnam National University Medical School. As social distancing was strengthened, the second class of the fifth module in both years was converted to an online format and the fifth module was excluded. The first four PBL modules were conducted as in-person classes, but the last PBL module was administered via videoconferencing. After the final PBL module, 100 (81.3%) first-year medical students and 90 (79.6%) second-year students were asked to complete a self-administered questionnaire on social presence and learning satisfaction. There were no significant differences in the small group activities of tutorial sessions between in-person and videoconferencing classes. In the online videoconferencing class, students who had favorable attitudes toward the tutors' social role and interactions with peers showed high satisfaction with their learning. In conclusion, online videoconferencing allows students to simultaneously perceive their interactions with others and social presence, even at a distance. Tutors can enhance a sense of online community and collaborative learning as facilitators of online PBL.

전자상거래 시장의 이용이 보편화 되며 고객들에게 좋은 품질의 물건을 어디서, 얼마나 합리적으로 구매할 수 있는지가 중요해졌다. 이러한 구매 심리의 변화는 방대한 정보 속에서 오히려 고객들의 구매 의사결정을 어렵게 만드는 경향이 있다. 이때 추천 시스템은 고객의 구매 행동을 분석하여 정보 검색에 드는 비용을 줄이고 만족도를 높이는 효과가 있다. 하지만 대부분 추천 시스템은 책이나 영화 등 동종 상품 분류 내에서만 추천이 이뤄진다. 왜냐하면 추천 시스템은 특정 상품에 매긴 구매 평점 데이터를 기반으로 해당 상품 분류 내 유사한 상품에 대한 구매 만족도를 추정하기 때문이다. 그밖에 추천 시스템에서 사용하는 구매 평점의 신뢰성에 대한 문제도 제시되고 있으며 오프라인에선 평점 확보 자체가 어렵다. 이에 본 연구에서는 일련의 문제를 개선하기 위해 RFM 다차원 분석 기법을 활용하여 기존에 사용하던 고객의 구매 평점을 객관적으로 대체할 수 있는 새로운 지표의 활용 가능성을 제안하는 바이다. 실제 기업의 구매 이력 데이터에 해당 지표를 적용해서 검증해본 결과 높게는 약 55%에 해당하는 정확도를 기록했다. 이는 총 4,386종에 달하는 이종 상품들 중 한번도 이용해 본 적 없는 상품을 추천한 결과이기 때문에 검증 결과는 상대적으로 높은 정확도와 활용가치를 의미한다. 그리고 본 연구는 오프라인의 다양한 상품데이터에서도 적용할 수 있는 범용적인 추천 시스템의 가능성을 시사한다. 향후 추가적인 데이터를 확보한다면 제안하는 추천 시스템의 정확도 향상도 기대할 수 있다.

Asynchronous Learning Networks (ALN) has become a kind of prevalent information systems to supplement or even substitute a traditional classroom face-to-face teaching method. In this paper, we investigate the impacts of types of courses, lecturers' instruction models and computer self-efficacy on the ALN effectiveness in teaching from lecturers' perspective. We conducted survey to professors in various faculties such as School of Computing, Faculty of Arts, Science, Business, Law and Engineering in the National University of Singapore. According to the responses from ninety-eight professors, instruction modes positively influence the usage of ALN; types of course and lecturers' computer-efficacy influence lectures' satisfaction of ALN in teaching. Both the usage of ALN and satisfaction of ALN positively influence the effectiveness of ALN. The results of this study fill the gap of ALN researches in education by examining it from lecturers' perspective and enable schools to improve their implementation of ALN systems based on our findings.

Purpose: This exploratory study aims to identify various factors influencing the level of nursing professionalism among nursing students. Methods: This study surveyed 246 senior nursing students in U city with a structured self-report questionnaire analyzed with SPSS 22.0. Results: The average scores for clinical practice learning environment, self-leadership, clinical practice belonging, and nursing professionalism were 3.16, 3.77, 3.53, and 3.60, respectively. There were significant differences in nursing professionalism according to the subjects' satisfaction with the nursing major and satisfaction with the amount of nursing. The most significant factors affecting nursing professionalism included clinical practice learning environment (${\beta}=.40$, p<.001), self-leadership (${\beta}=.21$, p=.001), and clinical practice belonging (${\beta}=.16$, p=.011). These variables explained 39% of the total variance in nursing professionalism. Conclusion: Clinical practice learning environment, self-leadership, and clinical practice belonging are factors in the nursing professionalism of senior nursing students. Collaborative efforts by universities and clinics are needed to improve the clinical training environment and to produce good nurses. Particularly since few studies have been conducted in Korea on clinical practice belonging, it is meaningful to explore how clinical practice belonging affects nursing professionalism.

The clinical practice program for home care nurses was implemented in June 1994, to help to set up a hospital-based home care system in the Kwangju City area as a collaborative work between the Department of Orthopedic Surgery at Chunnam University Hospital and Chunnam University School of Nursing. Under the developed clinical practice strategy, the eight week training was given to five licensed home care nurses who had completed Part I and II of the home health care nursing practicum from June 1994. The purpose of this descriptive evaluation study was to identify the effectiveness of the clinical practice program for home care nurses specialized in the area of patient care for people with musculoskeletal function impairment. As a method in data analysis, data triangulation was used in the five home care nurse case evaluations. The variety of data analyzed include confidence score by home care nurse self-evaluation, patient and family member satisfaction scores, and competency score by preceptor evaluation. The study findings revealed that an increase rate in nursing performance didrate necessarily coincide with an increase not in competency score and also, not with the patient /family member satisfaction scores. And an order derived from the clinical performance scores of five home care nurses corresponded to those from three measurements-competency score, patient satisfaction score, and family member satisfaction score. However, it differed from the order associated with the confidence score. Consistency derived from the three objective evaluation methods may lead to the possibility that the level of competency measured by educator can be further explained by the levels of patient/family member satisfaction. The salient finding of this study was that, in case of nurse A who have had little clinical experience in the orthopedic patient care, there was a significant increase in the level of confidence and competency in subscale of professional skill with the home care clinical practice. Therefore, the effect of the clinical practice program would be successful for nurses who have had little experience in the area of specialization. The study results suggest that there might be some time difference in the development of cognitive sense (confidence) in performance and actual clinical performance (competency). In future research, relationships between the confidence and competency score, and between the confidence score and the patient satisfaction score should to be measured in different time frame to achieve a better explanation power of the study outcome.
