The purpose of this study is to find the relationships among communication competency, social network centrality(trust centrality and knowledge sharing centrality), discussion performance, and online boarding activity in the team based learning situation. For investigating this topic, 44 students are participated in the classes of educational technology. In order to find out the relationships among communication competency, social network centrality, discussion performance, and online boarding activity, compared t-test and path analysis are used. Followings are the results of the research: (a) Communication competency is improved significantly after team based learning. (b) Trust centrality effects significantly on the knowledge sharing centrality. (c) Knowledge sharing effects significantly on discussion performance. (d) Trust centrality effects on the online boarding activity in the team based learning.

A variety of methods for indoor positioning systems have been underway to ensure the safety of emergency rescuers who are working in dangerous situations such as fire fighters. However, since most systems display locations of rescue workers in two-dimension (2D)-based maps, it is difficult for a commander located in the outside to recognize locations of rescuers inside the building intuitively. An augmented reality (AR)-based indoor positioning monitoring system can display locations of rescuer inside the building that can be seen by commanders to help intuitive recognition of positioning. To monitor AR-based indoor positioning, it is necessary to have an estimation technique of line of sight vector of observers. In the present study, an estimation technique of a line of sight vector using ultra-wide band tranceiver installed inside the indoor to trace locations is presented.

We have developed a prototype of a module-based patient monitor. In this paper, we describe the design methodology and specifications of the developed module-based patient monitors. The monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases, each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and $SpO_2$ with plethysmograph.

교수자가 학생들의 자율적인 팀 결성의 행동적 특성을 파악하는 것은 교과에서 팀 활동을 효과적으로 지도하기 위해 필요하다. 본 연구에서는 에이전트 기반의 컴퓨터 시뮬레이션을 통해 학생들의 팀 결성 행동 특성을 모사할 수 있는 컴퓨터 모형을 개발하였다. 실험을 통한 검증 결과 개발된 모형은 실제 학생들의 행동적 특성을 모사할 수 있음이 관찰되었다. 학생의 수와 팀원을 찾는 탐색의 범위가 클수록 팀의 결성이 안정화되기까지의 시간이 줄어들며 팀원을 찾지 못한 학생의 비율 또한 줄어들지만 어느 한계를 넘어서면 시간과 비율에 있어 큰 차이가 없음을 발견하였다. 또한 융 복합 교과 등에서 구성원 간의 이질성이 증가한다면 팀 구성 시간과 팀원을 찾지 못한 학생의 비율이 급격히 증가하므로 경우에 따라 교수자가 학생들의 팀 구성에 적절하게 개입하는 것이 필요함을 알 수 있었다. 개발된 모형을 통해 모의실험 함으로써 학생들의 팀 결성의 성격과 구조를 진단하고 분석할 수 있으므로 개발된 모형은 학생들의 팀 활동을 지원하는 도구로 유용하리라 기대한다.

Purpose: For improving outgoing quality, this study presents a novel sampling framework based on predictive analytics. Methods: The proposed framework is composed of three steps. The first step is the variable selection. The knowledge-based and data-driven approaches are employed to select important variables. The second step is the model learning. In this step, we consider the supervised classification methods, the anomaly detection methods, and the rule-based methods. The applying model is the third step. This step includes the all processes to be enabled on real-time prediction. Each prediction model classifies a product as a target sample or random sample. Thereafter intensive quality inspections are executed on the specified target samples. Results: The inspection data of three Samsung products (mobile, TV, refrigerator) are used to check functional defects in the product by utilizing the proposed method. The results demonstrate that using target sampling is more effective and efficient than random sampling. Conclusion: The results of this paper show that the proposed method can efficiently detect products that have the possibilities of user's defect in the lot. Additionally our study can guide practitioners on how to easily detect defective products using stratified sampling

IT project teams are composed of experts from various domains with different backgrounds, such as business and technologies. Thus, enhancing knowledge sharing and increasing team social capital are critical for the success of the project. This study examines the relationship among the team social capital, team climate and team performance. A research model and hypotheses are developed from literature review and empirically validated. The research model consists of team social capital, team climate and team performance. Specifically, team social capital, as antecedents, wasconceptualized asinternal and external differentiated by team boundary, and team climate is conceptualized as innovative climate and supportive climate. Using measures adopted from previous studies, 166 data points were collected to test the research model and related hypotheses. PLS data analysis indicated that internal and external social capitalhave positive effect on innovative climate while internal social capital has a positive effect on supportive team climate. The innovative and supportive climate has significant effect on the team performance. Based on the results, we proposed several team management skills for IT project managers. Theoretical constributions are discussed at the end with limitations and further studies.

팀을 기반으로 한 조직구조가 확산되면서, 많은 조직구성원들이 팀원으로서의 역할을 수행하고 있다. 이러한 상황은 조직구성원들에게 팀이라는 또 하나의 중요한 몰입대상을 제공했을 뿐만 아니라, 갈등의 경험가능성 역시 증가시켰다. 그러나 팀 내 갈등과 팀몰입 사이의 관계를 다룬 연구는 아직까지 많지 않다. 이에 본 연구는 과업갈등과 관계갈등이 팀몰입에 영향을 미치는 과정에서 팀효능감과 커뮤니케이션 만족도의 차별적인 매개효과를 검증하고자 하였다. 분석을 통해 확인된 결과는 다음과 같다. 첫 째, 과업갈등과 관계갈등은 팀몰입에 부정적인 영향을 미쳤다. 둘 째, 팀효능감은 과업갈등과 팀몰입 사이를 완전 매개하였다. 셋 째, 커뮤니케이션 만족도는 관계갈등과 팀몰입 사이를 완전 매개하였다.

Purpose: This study aimed to introduce active learning methods, including flipped, case-based, and team-based learning in an electrocardiography (ECG) course and to investigate outcomes and satisfaction with these methods. Methods: To identify the learning effect of active learning, pre-and post-academic self-efficacy was compared between the experimental and control groups. In the experimental group, pre-and post-knowledge and clinical performance regarding ECG were also assessed. In addition, class satisfaction was investigated after application of active learning methods in the experimental group. Data were collected from 84 paramedic students and analyzed using SPSS 22.0 (IBM, Armonk, NY, USA). Results: The experimental group showed significant improvement in post-academic self-efficacy and knowledge. The experimental group also showed high clinical performance (9.83 out of 10 in ECG checking ability and 9.63 out of 10 in ECG reading ability). The mean satisfaction score was 4.23 out of 5 (responses based on a Likert scale) in the experimental group. Conclusion: Active learning in an ECG course was found to be highly effective and satisfactory. Furthermore, paramedic students can enhance their accountability and judgement with team-based learning through free engagement in discussion.
