Recently, knowledge transfer has been recognized as one of the major factors for success of IT projects but little investigated in Information Systems research. IT project, which needs collaboration between organization's IT project team and external partner, is an critical source for a firm to acquire external knowledge and to achieve its competitive advantage. Based on this recognition on knowledge transfer under IT project, we investigate a mediation role of knowledge transfer to IT project performance after identifying its antecedents such as project team capabilities and partner capabilities. The research model is tested by analyzing 161 sample data gathered from firms' employees who have participated IT projects within last two years. The results reveal that knowledge transfer has full-mediation effect between its antecedents and IT project performance. Moreover, project team capabilities have more impacts on knowledge transfer than partner capabilities do.

본 연구는 먼저, 새천년 이후의 리더십 관련 연구들을 이론적으로 분석하여 현대리더십 이론 연구의 두 가지 특징을 제시하였다. 첫째는 대부분의 이론들이 변혁적리더십 이론과의 중복성이 높다는 점이고, 둘째는 공유/분산적리더십을 중심으로 한 수평적 리더십 연구의 발전이다. 다음으로, 본 연구에서는 공유/분산적리더십 이론의 효과성을 선행연구를 기초로 분석하고, 공유/분산적리더십이 구성원의 성과인식과 팀 혁신행동에 미치는 영향을 실증분석 하였다. 그 결과, 공유/분산적리더십이 구성원의 성과인식과 팀 혁신행동에 유의적 영향을 미친다는 것을 검증하였다. 그러나 경쟁지향문화의 조절효과 검증에서는 공유/분산적리더십과 구성원의 성과인식 사이에 경쟁지향문화의 조절효과가 검증되지 않았다. 그것은 한국기업의 경우, 경쟁지향문화 속에서는 공유/분산적 리더십의 효과가 구성원의 성과인식을 조절하지 못한다는 것이다. 기업의 문화적 가치에 따라 그 성과에는 차이가 날 수 있다는 점을 시사한다.

Interprofessional education (IPE) fosters effective team-based collaborative practice among members of different health care professions to advance high-quality and safe patient care. Although the importance of IPE has been recognized and IPE initiatives have expanded rapidly in the past decades, substantial difficulties in IPE assessment still exist. At present, a lack of consensus on the optimal approach to IPE assessment contributes to uncertainty about the level of attainment of collaborative team performance. This paper aims to provide an overview of the benefits and current challenges associated with IPE assessment. Furthermore, a multifactor model with an assessment matrix and assessment blueprints from a recent study is briefly discussed. We also provide examples of assessment blueprints for the team management of stroke patient discharge covering a competency examination at the levels of individuals, the team, and the task.

This paper aims to share the course, performance and implications of Project-Based Learning (PBL) education in healthcare data science (HDS). The HDS team of the business group of Soonchunhyang University, which was selected for the health care field of 'University Innovation Project', considered that the health care IT-based education of the current university differs greatly from the rapidly changing health care 3.0 environment of the fourth industry, and emphasized the PBL practice-oriented specialization program as a learning model. The PBL focused on self-directed learning experiences, real analysis problems, and team-oriented classes. In other words, it was implemented with three specialized strategies: 'Field Inside Education', 'Fusion-type Track Education', and 'Training to strengthen resilience and change response'. This collaborative, practical learning experience, etc. resulted in significant results. The results were recognized as being rated A by the Korea Research Foundation and the comprehensive evaluation, and the results were significantly elevated through the analysis of the student survey and the results index.

This study was prepared to present the research data for the promotion of Korean foods and restaurants in Korea and abroad by an analysis of the recognition and preference of Korean traditional foods and an importance-performance analysis of Korean restaurants by foreign visitors (n=351) and foreign residents (n=365). The most recognized Korean foods among foreigners were Bibimbap>Kimchi>Bulogi>Galbi>Samgyetang;however, the most preferred Korean foods were statistically different; Bibimbap>Kimchi>Bulgogi>Galbi>Rameyeon by foreign visitors and Bulgogi>Bibimbap>Galbi>Samgyetang>Kimchi by foreign residents. Especially, the preferences for Samgyetang and Dakgalbi were increased whereas that for Kimchi was decreased in foreign residents. The Korean foods were described as 'hot and pungent' and 'spicy' by foreign visitors, but 'hot and pungent', 'non-greasy' and 'salty' by foreign residents. In choosing a restaurant, 'quality of food' was most important among foreigners, but 'proper price' was considered more significant than 'sanitation and cleanness' by foreign residents compared with foreign visitors. The satisfaction with Korean restaurants of foreign residents was lower than that of foreign visitors. An analysis of importance and performance of Korean restaurants by foreigners was performed. There were significant differences in the evaluations of Korean restaurants between foreign visitors and foreign residents (p<0.05). The importance of the attributes related with 'foods' and 'sanitation' were rated higher by foreign residents. On the other hand, foreign visitors rated the importance of the attributes related to 'eating environment' and 'employees' more highly. Foreign residents significantly rated the performances of Korean restaurants lower in each attribute except 'additional free side dishes' and 'communications'.

This study was conducted to determine whether level-1 emergency medical technicians (EMTs) can adequately recognize ST-segment elevation myocardial infarction (STEMI) in the emergency department (ED) and whether their ability to do so differs from that of emergency medicine physicians (EMP). From December 2022 to November 2023, patients aged 20 years or older visiting the ED with chief complaints suggesting acute coronary syndrome (ACS) were enrolled. As soon as the patient arrived at the ED, a level-1 EMT conducted a 12-lead electrocardiogram (ECG) to assess STEMI; an EMP subsequently assessed whether to activate the percutaneous coronary intervention team. Demographic characteristics, test results, and final diagnoses were collected from the medical records. Among the 723 patients with case report forms, 720 were included in the analysis. These were categorized as follows: 117 (16.3%) with STEMI, 159 (22.1%) with non-ST-segment elevation ACS, and 444 (61.7%) with other conditions. STEMI was correctly recognized in 100 patients (91.7%) by level-1 EMTs and in 104 patients (95.4%) by EMPs (kappa=0.646). EMTs with less than 1 year of ED work experience correctly recognized 60 out of 67 STEMI patients (89.6%), which was comparable with the EMPs who recognized 65 out of 67 STEMI patients (97.0%, kappa=0.614). EMTs with more than 1 year of ED work correctly recognized 40 out of 42 STEMI patients (95.2%), and therefore performed better than EMPs, who recognized 39 out of 42 STEMI patients (92.9%, kappa=0.727). The level-1 EMTs adequately recognized STEMI using a 12-lead ECG and were in substantial agreement with the evaluations of the EMPs.

Human capabilities, such as technical/nontechnical skills, have begun to be recognized as crucial factors for nuclear safety. One of the most common ways to improve human capabilities in general is training. The nuclear industry has constantly developed and used training as a tool to increase plant efficiency and safety. An integrated training framework was suggested for one of those efforts, especially during simulation training sessions of nuclear power plant operation teams. The developed training evaluation methods are based on measuring the levels of situation awareness of teams in terms of the level of shared confidence and consensus as well as the accuracy of team situation awareness. Verification of the developed methods was conducted by analyzing the training data of real nuclear power plant operation teams. The teams that achieved higher level of shared confidence showed better performance in solving problem situations when coupled with high consensus index values. The accuracy of nuclear power plant operation teams' situation awareness was approximately the same or showed a similar trend as that of senior reactor operators' situation awareness calculated by a situation awareness accuracy index (SAAI). Teams that had higher SAAI values performed better and faster than those that had lower SAAI values.

As more satellites are designed to downlink their observed image data through the X-band frequency band, it is inevitable that the occupied bandwidth of a target satellite will overlap with that of other X-band downlink satellites. For sun-synchronized low earth orbit satellites, in particular, it can be expected that two or more satellites be placed within the looking angle of a ground station antenna at the same time. Due to the overlapping in the frequency band, signals transmitted from the adjacent satellites act as interferers, leading to degraded link performance between target satellite and ground station. In this paper, link analysis was initiated by modeling the radiation pattern of ground station antenna through a validated Jet Propulsion Laboratory peak envelope model. From the relative antenna gain depending on the offset angle from center axis of maximum antenna directivity, the ratio of received interference signal level to the target signal level was calculated. As a result, it was found that the degradation increased when the offset angle was within the first point of radiation pattern. For a 7.3 m antenna, serious link degradation began at an offset angle of 0.4 degrees. From this analysis, the link performance of the coming satellite passes can be recognized, which is helpful to establish an operating procedure that will prevent the ground station from receiving corrupted image data in the event of a degraded link.
