Background and objectives: This study analyzed the effectiveness of the online practical classes (OPC) in physical education (PE) in compliance with the ADDIE model during the COVID-19 pandemic. Materials and Methods: Participants had no prior experience in OPC and total 75 participants were enrolled in this study. This study selected 15 universities in consideration of regional equality and randomly selected two professors and three students from each university. Results: (1) The learning inter

Purpose The purpose of this paper is to develop a research model examining users' perceived value of a location-based social networking service (LB-SNS) through hedonic, utilitarian, and social values. This study investigates the impact for each type of perceived value on user satisfaction, behavioural intention to use, and word-of-mouth for LB-SNS.

The metaverse has been evolving the internet-based education represented by e-learning. Metaverse technology is currently being developed as a platform centered on content-based information industries. It can be classified into four categories: augmented reality, lifelogging, mirror worlds, and virtual worlds. Although current research finds that the potential of the metaverse is not small in the education world, and metaverse technology is already being used in the sports world, concrete applic

Cooperative Communication (CC) is a technology that allows multiple nodes to simultaneously transmit the same data. It can save power and extend transmission coverage. However, prior research work on topology control considers CC only in the aspect of energy saving, not that of coverage extension. We identify the challenges in the development of a centralized topology control scheme, named Cooperative Bridges, which reduces transmission power of nodes as well as increases network connectivity. W

Mobile RFID, the technology of a cellular phone equipped with a RFID reader, allows users to read RFID tags anywhere. However, signals from more than two readers can interfere with one another, i.e., reader collision problem; reliable tag reading is necessary. This paper proposes GENTLE protocol to use beacon messages and multi-channel for increasing throughput. GENTLE protocol can also put tag ID information into the beacon message and share it among close readers. In addition, we suggest LSWBT

Topology control is to determine the transmission power of each node so as to maintain network connectivity and consume the minimum transmission power. Cooperative Communication (CC) is a new technology that allows multiple nodes to simultaneously transmit the same data. It can save transmission power and extend transmission coverage. However, prior research work on topology control considers CC only in the aspect of energy saving, not that of coverage extension. We observe that CC can bridge (l

경력열망은 조직에서 자신이 관리자로서 능력을 발휘할 수 있다고 믿으며, 현재보다 더 높은 수준의 지위로 이동하고자 하는 의지다. 여성의 경력열망은 남성의 경력열망보다 낮은 것으로 보고된다. 기업조직의 성불평등 메커니즘으로 인해 자신이 이룬 성취에 적절한 인정을 받지 못하기 때문이다. 연구는 여성의 경력열망에 영향을 미치는 구조적 요인을 분석해 일반화된 함의를 도출하고자한다. 자료는 6차(2016년), 7차(2018년) 여성관리자패널을 이용하고, 676명의 여성관리자와 181 개의 기업을 대상으로 한다. 주요 결과는 다음과 같다. 첫째, 멘토는 여성의 경력열망에 긍정적인영향을 미친다. 여성관리자에게 멘토는 고위 관리직 및 동료들에게 접근할 수 있는 기회이며, 신뢰와 지원을 얻을 수 있는 수단으로 작용해 경력열망을 높인다. 둘째, 조직에서 여성관리자의 비율이높을수록 여성의 경력열망은 떨어진다. 여성관리자들은 다른 여성관리자의 존재를 경쟁자로 인식하며, 여성 상사의 높은 기대감은 심리적인

이 논문은 제 18대, 19대 국회의원들이 제출한 대표발의안을 토대로 국회내부의 국회의원, 상임위원회 간에 형성된 네트워크 분석을 통해 개별 국회의원과 정당, 상임위원회의 입법활동을 평가하는데 활용함을 목적으로 한다. 본 연구는 이원모드 네트워크 프로젝션(Bipartite Network Projection)의 방법으로 의원들이 상임위원회에 제출한 대표발의안을 토대로 어느 위원회가 중심적인 역할을 하는지와 위원회간의 관계를 파악한다. 두 번째는 같은 방법으로 국회의원들 중 대표발의안을 다양한 위원회에 제출하여 다른 의원들과의 활동 위원회의 교집합이 큰 의원을 찾을 수 있다. 제 18대, 19대 국회의원 중 여당과 제1야당을 분석대상으로 삼아 비교하였다. 본 연구를 통해 국회의원들의 발의안 제출 영역을 통한 협업 평가의 기준으로 활용이 가능함을 보인다.

Many Korean English teachers usually assess learners’ writing according to their subjective judgement without using any rating scale in the writing class. The validity of assessment has been the main issue in the language testing field. This study aims to examine the validity of the assessment categories in their subjective holistic scoring of their EFL students’ English writing. For this purpose, three English teachers at various high schools participated as raters. When assessing given writing

Since the COVID-19 pandemic negatively affects the daily lives, psychophysical conditions, and immunocytes of adolescents, there is an urgent need to create and provide solutions to adolescents with depression though the number of subjects is few.
