Nationalism can solidify national unity and ideology but sometimes causes conflicts in human societies. Interestingly, it affects tiger conservation as well. Collaborative efforts are imperative for tiger conservation due to their vast home ranges which cross political boundaries and the limited financial resources. However, tiger states have not shown substantial commitment to collaboration. The nationalism that is entrenched in tiger conservation provides a credible explanation for this passive collaboration among nations. One type of nationalism occurs within a country by favoring one particular subspecies over another. The other type of nationalism occurs when former range countries want tigers. Instead of contributing to saving tigers in current habitats, they are eager to bring tigers back to their political boundaries regardless of the tremendous financial resources required and the lower chance of success. Considering nationalism in tiger conservation, tigers, just like humans, may need a passport for a better chance to survive.

Nowadays, team members often use mobile messenger service (MMS) in performing team projects. Team members can freely express their ideas or opinions using MMS without any restrictions in terms of place and time. But, in team project, using MMS is pressing them to perform their project more quickly than off-line conference, and assigning a role outside the range of their ability. In other words, team members can recognize work overload by utilizing MMS and this work overload can lead to team conflict. This study examines the effect of work overload through MMS use on team performance. We consider team engagement and team trust as the key drivers of team performance. However, team conflict will obstruct team engagement and team trust. Research model was analyzed by 135 university students who were doing several team projects. The analysis results show that work load through MMS use has a significant effect on team conflict. In other words, when work load is increased by utilizing MMS, it leads to team conflict. This team conflict loses trust between team member and hinders team performance. Lastly, this research provides several implications for right usage of MMS to improve team project performance.

The increasing complexity of complex buildings, such as high-rise buildings and underground subway stations, presents new challenges to firefighters. In a fire in complex buildings, the importance of the collaboration between firefighters is clear. The increased demand on firefighter training for such environment is now evident. Due to cost, time, and safety issues, it is impossible to experience a real fire in such environments for training. In addition, the use of real fire for training does not enable repeatable training and the evaluation of the training is difficult. We developed a team-based firefighter training simulator for complex buildings using the virtual reality technology. It provides the training and evaluation of firefighting and mission-based team training. To model real fire phenomena in virtual space, a numerical analysis method based on fire dynamics is used. To achieve an immersive virtual environment, an augmented reality technique for the compensation of real world image and a haptic technique for heat experience are adopted. The developed training simulator can help the firefighter to respond to large and complex firefighting scenarios, while maintaining the safety of the trainees.

The purpose of this study is to explore and develop a new instructional approach to a technology-enhanced, collaborative learning environment called Smart technology-enhanced Team-Based Learning (S-TBL). We designed a novel instructional model that combines mobile technology, collaborative teamwork, a problem-solving process, and a variety of evaluation techniques from the viewpoint of a conventional team-based model. Based on the traditional TBL model, we have integrated smart learning technologies: 1) to provide a holistic learning environment that integrates learning resources, assessment tools, and problem solving spaces; and 2) to enhance collaboration and communication between team members and between an instructor and his or her students. The S-TBL instructional approach combines: 1) individual learning and collaborative team learning; 2) conceptual learning and problem-solving & critical thinking; 3) both individual and group assessment; 4) self-directed learning and teacher-led instruction; and 5) personal reflection and publication.

In the database design course, the team project is a very important process to develop students' database design competencies. In order to carry out team projects smoothly, active interaction between students and the professor as well as collaboration among team members are very important. However, a full uncontacted class was suddenly decides in the first semester of 2020, it was questionable whether it would be possible to effectively manage this course, where team projects to construct database take up a big portion. However team projects were able to proceed without major problems through interaction using real-time video media such as zoom, and discussions, quizzes, and Q&A supported by the online education support system (LMS), and online presentations, mutual evaluations, and so on. This paper shares the experience of managing engineering team projects in uncontacted classes and based on three surveys introduces desirable improving directions of this instruction and some suggestions to improve uncontacted classes overall.

When it comes to 'Team Medical Care' in Japan, clinical laboratory technologists have actively engaged in various kinds of teams, such as a diabetes team, a nutrition support team, an infection control team and a medical practice support team. Overall, with continual changes in the medical environment, clinical laboratory technologists are recently being required to not only conduct phlebotomy, specimen collection, laboratory testing, and electrocardiography, but also get actively involved in 'medical practice assistance or support' in collaboration with medical doctors and nurses. Therefore, it is anticipated that resident clinical laboratory technologists in wards or emergency rooms in Korea will be better able to contribute to improving medical quality and securing medical safety by functioning as a link to the clinical laboratory, while medical doctors and nurses will have a reduced burden of work and can dedicate themselves to better patient care.

최근 MOM 기술은 비즈니스 로직을 수행하는 애플리케이션 서버의 필수적인 구성요소로서 자리잡고 있으며, 보통 수백에서 수천의 클라이언트 요청을 처리할 수 있는 능력을 제공한다. MOM 은 이러한 대용량의 클라이언트 요청을 효과적으로 처리하기 위해서 효율적이고 확장성있는(스케일러블) 네트워크 모듈이 필요하며, 다양한 네트워크 프로토콜을 지원해야 한다. MOM이 기본적으로 지원하는 메시징 기능은 PTP(Point-To-Point)와 publish/subscribe 메시징 도메인으로 나뉘는데 이 논문에서는 두 가지 메시징 도메인과 그룹통신 메시징 서비스 기능을 동시에 지원하는 MoIM-Message 시스템의 하부 통신 모듈의 설계에 대해 기술한다. PTP와 publish/subscribe 메시징을 지원하기 위해 세가지 프리미티브 메시징 오퍼레이션인 "synchronous send", "synchronous receive", "asynchronous receive"를 정의하였으며 하부 통신 모듈 역할을 하는 메시지 트랜스포트 관리 계층내의 트랜스포트 관리자 내에 구현되었다. 트랜스포트 관리자는 다양한 트랜스포트 프로토콜을 적용할 수 있도록 하기 위해 트랜스포트 어댑터로 설계되었으며, 대량의 통신 요청을 효과적으로 처리하기 위해 "polling with multiple service thread model" 기법을 적용하여 구현되었다. 또한, 모바일 클라이언트 환경을 지원하기 위해 클라이언트 측 통신 모듈을 IPaq PDA 상에 포팅하였다. 본 논문에서 제안하는 세 가지 프리미티브 메시징 오퍼레이션을 제공하는 통신 모듈은 MOM이 기본적으로 지원해야 할 메시징 도메인과 대용량의 클라이언트 요청을 효율적으로 처리할 수 있는 구조를 가진다.es}8$ 모드를 모두 사용한 경우와 $8{\times}8$ 단일모드를 사용한 경우보다 계산 시간이 감소하였음을 확인하였다.행중인 MoIM-Messge서버의 네트워크 모듈로 다중 쓰레드 소켓폴링 모델을 적용하였다.n rate compared with conventional face recognition algorithms. 아니라 실내에서도 발생하고 있었다. 정량한 8개 화합물 각각과 총 휘발성 유기화합물의 스피어만 상관계수는 벤젠을 제외하고는 모두 유의하였다. 이중 톨루엔과 크실렌은 총 휘발성 유기화합물과 좋은 상관성 (톨루엔 0.76, 크실렌, 0.87)을 나타내었다. 이 연구는 톨루엔과 크실렌이 총 휘발성 유기화합물의 좋은 지표를 사용될 있고, 톨루엔, 에틸벤젠, 크실렌 등 많은 휘발성 유기화합물의 발생원은 실외뿐 아니라 실내에도 있음을 나타내고 있다.>10)의 $[^{18}F]F_2$를 얻었다. 결론: $^{18}O(p,n)^{18}F$ 핵반응을 이용하여 친전자성 방사성동위원소 $[^{18}F]F_2$를 생산하였다. 표적 챔버는 알루미늄으로 제작하였으며 본 연구에서 연구된 $[^{18}F]F_2$가스는 친핵성 치환반응으로 방사성동위원소를 도입하기 어려운 다양한 방사성의 약품개발에 유용하게 이용될 수 있을 것이다.었으나 움직임 보정 후 영상을 이용하여 비교한 경우, 결합능 변화가 선조체 영역에서 국한되어 나타나며 그 유의성이 움직임 보정 전에 비하여 낮음을 알 수 있었다. 결론: 뇌활성화 과제 수행시에 동반되는 피험자의 머리 움직임에 의하여 도파민 유리가 과대평가되었으며 이는 이 연구에서 제안한 영상정합을 이용한 움직임 보정기법에
