The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.

Objectives : The purpose of this study is to evaluate the effectiveness and safety of topical nasal application of Herbal medicine compared with Western medicine in the treatment of Allergic Rhinitis(AR). Methods : Electronic databases including Cochrane library, PubMed, EMBASE, CNKI, KMBASE, KISS, NDSL, OASIS, KISS and KJTK(Korean Traditional Knowledge Portal) were searched by the keywords such as 'allergic rhinitis', 'nasal sprays', 'herbal medicine', 'plant extracts', and 'external application'. The quality of each RCTs was assessed by Cochrane Collaboration of 'Risk of bias(RoB) Tool'. Results : 19 RCTs were finally selected from 1419 references screened. 19 RCTs were compared with the effects of topical nasal application of Herbal medicine and Western medicine. Based on the symptom scores from 13 RCTs, topical nasal application of herbal medicine generally has a better effect on relief of AR. The two treatments have similar effects on improving the level of specific factors like IgE, IgG, IL-13, $uLTD_4$ in blood and urine. 8 RCTs showed adverse effects(AEs) in both groups and severe AEs were not reported. Conclusions : This study shows that topical nasal application of herbal medicine can improve symptoms and related factors of allergic rhinitis. Well-designed RCT studies with low risk of bias should be conducted to confirm these findings.

최근 건설 프로젝트의 효율적인 관리를 위해 현장에서 각 사업주체(발주, 설계, 감리, 시공, 협력업체)간 원활한 의사소통, 협업, 정보공유 및 교환을 위하여 사업관리시스템인 PMIS(Project Management Information System)를 많이 사용하고 있다. 그러나 이러한 개별 프로젝트단위로의 시스템 개발은 회사 전체 프로젝트관리 효율성 및 통합화에 저해요인으로 지적되고 있다. 이는 프로젝트단위로 개발되는 사업관리시스템의 특성상 전사차원의 시스템개발 및 보급을 위한 Master Plan인 ISP(Information Strategy Plan) 즉 정보화 전략의 수립의 부재에 기인한다고 볼 수 있다. 본 논문은 실제 대형 건설회사인 국내 D건설사의 PMIS구축을 위한 정보화전략계획(ISP) 수립방법 및 절차의 사례를 소개하고 전사 PMIS구조, 전사업무프로세스 개선과 시스템 구축방법 및 성공요소 등을 제시한 논문이다. 이 연구 논문을 통해 향후 건설회사의 사업관리 시스템 구축 시 효율적인 PMIS개발과 최적화시스템을 구축에 도움이 되고 정보화 전략계획 수립에 활용 할 수 있기를 기대한다.

국내 외 건설공사에서 건물의 전 생애주기 동안에 발생되는 정보의 관리 및 통합이 가능한 BIM 적용이 활발해지고 있다. BIM을 시공단계에 활용할 경우 공기단축, 재시공 감소, 협업능력 향상 등의 효과가 있다. 그러나 국내 BIM 지침서 정의수준 부족, 설계 기준의 미비 때문에 시공단계에 BIM을 적용하는데 한계가 있다. 특히, 설계 단계에 비해 시공단계에서는 MEP 분야는 그 중요성이 훨씬 커진다. 따라서 본 연구는 시공단계의 MEP 분야에서 BIM활용도를 높이기 위하여, 시공 BIM MEP 모델 요구조건 체크리스트를 개발하였다. 체크리스트 개발을 위하여 국내 외 BIM 지침서 및 시공 BIM이 적용된 민간 공공 공사의 사례를 분석하였다. 지침서 및 사례를 토대로 작성객체 31개, 속성기준 31개, 총 62개의 시공 BIM 모델 요구조건을 도출하였다. 도출한 62개의 요구조건을 활용목적과 필요사항으로 구분하여 시공 BIM MEP모델 요구조건 체크리스트를 제안하였다. 본 연구에서 제안한 체크리스트를 실무에서 활용한다면 시공단계 MEP BIM 모델의 활용도를 향상시킬 수 있을 것으로 기대된다. 또한 학문적인 측면에서 시공단계 BIM 모델의 표준화된 지침서 개발에 활용될 기초연구로서 의미가 있다.

Purpose: The current challenges faced by nurses in providing high quality and evidence-based practice (EBP) supported care require profound changes in nursing education. To understand the changes needed to strengthen EBP education, the researchers examined EBP self-efficacy, course needs, barriers, and facilitators for academic faculty and clinical nurse preceptors to teach EBP in undergraduate nursing curricula. Methods: For this study, mixed-method approach was used with survey data collected from 73 academic faculty members from 54 universities. Further, 17 clinical nurse preceptors in three academic hospitals provided qualitative data for exploration of barriers and facilitators to teaching EBP. Data analysis used SPSS/WIN 21.0 and content analysis. Results: Quantitative data showed that although the overall level of self-efficacy among faculty was moderate, the implementation levels were relatively low. Most faculty members agreed with the need to integrate EBP courses into undergraduate nursing curricula. The qualitative data showed that the barriers to teaching EBP were lack of knowledge, skill, and initial investment for teaching EBP; hierarchical, rules-oriented nursing culture; potential learner overloads in processing EBP; limited research dissemination and application. Facilitators were identified as the importance of EBP to the profession of nursing; collaboration in schools and hospitals; and continuing education in teaching/utilizing EBP. Conclusion: The findings indicate that for successful integration of EBP ni nursing education there is a need for faculty training and integrated EBP courses.

Contemporary University students are considered the Z generation who were born after 1995. They are more tech savvy than millennials. To target the generation, traditional class management platforms have evolved to smart LMS that is more customized and accessible for smart devices. Global level information search and collaboration can also be implemented using such smart LMS. However, switching from one LMS to another LMS requires great effort from teachers and support from staffs. This study measured the learners' perception of the system when they were exposed to a new smart-LMS. Blackboard Learn Ultra was used for 15 weeks and at the end of the semester, a questionnaire was administered to the students of these classes. Results indicated that experience with previous LMS discouraged students from adopting Blackboard Learn. Result of TAM modeling indicated that perceived usefulness, compared to perceived ease of use and attitude, was an effective aspect to bring positive acceptance of the system. A qualitative approach and network analysis were also conducted based on students' responses. Both positive and negative responses were detected. Inconvenience due to mechanical aspects was mentioned. Dissatisfaction compared to previous local LMS use was also mentioned. Mobile application and communication effectiveness were positive aspects. Revised course development and promoting how useful the system may help enhance the acceptance of the new system.

Agriculture production is a critical human intensive task, which takes place in all regions of the world. The process to grow and harvest crops is labor intensive in many countries due to the lack of automation and advanced technology. Much of the difficult, dangerous and dirty labor of crop production can be automated with intelligent and robotic platforms. We propose an intelligent, agent-oriented robotic team, which can enable the process of harvesting, gathering and collecting crops and fruits, of many types, from agricultural fields. This paper describes a novel robotic organization enabling humans, robots and agents to work together for automation of gathering and collection functions. The focus of the research is a model, called HARMS, which can enable Humans, software Agents, Robots, Machines and Sensors to work together indistinguishably. With this model, any capability-based human-like organization can be conceived and modeled, such as in manufacturing or agriculture. In this research, we model, design and implement a technology application of knowledge-based robot-to-robot and human-to-robot collaboration for an agricultural gathering and collection function. The gathering and collection functions were chosen as they are some of the most labor intensive and least automated processes in the process acquisition of agricultural products. The use of robotic organizations can reduce human labor and increase efficiency allowing people to focus on higher level tasks and minimizing the backbreaking tasks of agricultural production in the future. In this work, the HARMS model was applied to three different robotic instances and an integrated test was completed with satisfactory results that show the basic promise of this research.

As an advanced study on the method of calculating the target revenue water ratio of local waterworks through the leakage component analysis method proposed by Kim et al. (2022), this study developed a model to calculate the achievable revenue water ratio within the specified project cost, the required project cost to achieve the specified target revenue water ratio, and the economically appropriate target revenue water ratio level by considering the leakage reduction cost and leakage reduction benefit for each revenue water ratio improvement strategy, and conducted an applicability evaluation of the developed model using actual field data. The procedure for calculating the target revenue water ratio of local waterworks considering economics proposed in this study consists of three stages: physical data linkage model construction, leakage component analysis, and economic analysis, and the applicability was evaluated for Zone H with branch type and the Zone M network type. As a result of the application, it was calculated that approximately 32.5 billion won would be required to achieve the target revenue water ratio of 70% in the Zone H, and approximately KRW 10.5 billion would be required to achieve the target revenue water ratio of 75% in the Zone M. If the business scale of Zones H and M was corrected to 10,000 m³/day of water usage, the required project cost for a 1% improvement in the revenue water ratio of Zone H was calculated to be 0.7642 billion won and 0.4715 billion won for Zone M.
