본 연구의 궁극적 목적은 소방활동 현장지휘관의 대응역량 강화이며, 그 일환으로 훈련용 콘텐츠 시나리오를 개발하였다. 현장지휘관의 상황판단력, 커뮤니케이션, 의사결정력을 3가지 핵심역량으로 설정하였다. 이 3가지 핵심역량이 시나리오 체계구성시 적극 반영될 수 있도록 구축하였다. 본 시나리오의 모든 내용은 재난현장 표준작전절차 SOP를 기반으로 구성하였다. 시나리오의 체계는 전체 14단계로 구성되며, 훈련의 시작과 마지막인 1단계와 14단계를 제외하면, 크게 4단계로 구분된다. 상황설정 단계와 1, 2, 3차 의사결정 단계로 구성되며, 특히 상황판단과 커뮤니케이션은 각 단계마다 중요한 요인이다.

본 연구는 정상 성인 20명을 대상으로 복부 안정화에 영향을 미치는 노르딕 워킹과 파워 워킹을 2주간 집중 시행한 후, 복부중심 근육(배속빗근, 배바깥빗근, 배가로근)의 활성도 및 두께, 그리고 복부 피하지방의 두께 변화를 비교하였다. 연구 결과, 근전도를 이용한 배속빗근과 배바깥빗근의 근활성값은 노르딕 워킹과 파워 워킹군 모두에서 훈련 후 높게 나타났으며, 특히 노르딕 워킹 훈련군의 경우 파워 워킹 훈련군에 비해 통계학적으로 유의하게 높은 근활성도의 변화를 보였다. 초음파를 이용한 배가로근과 배속빗근, 배바깥빗근의 두께는 노르딕 워킹 훈련군과 파워 워킹 훈련군 모두에서 통계학적으로 유의한 증가를 나타내었으나 군간 변화 차이는 없었다. 노르딕 워킹은 스틱을 이용하여 균형 안정감을 제공하며 상지와 하지의 큰 움직임을 통해 복부 안정화를 유도하는 효과적인 훈련방법으로써 다양한 재활운동의 형태로 적용하기에 유용할 것으로 여겨진다.

Objectives: Despite greater access to training positions and the presence of more women in emergency medicine, it has remained a men-dominated field. This study aims to identify the key issues causing the gender gap in Korea and establish measures to overcome them. Methods: Using the annual statistical reports of the National Emergency Medical Center and data published on the Korean Society of Emergency Medicine website, cases that listed the current status and positions of members in its organization and its committees were analyzed. Secondary analysis was conducted using data from the 2015 Korean Society of Emergency Survey that included physicians' demographics, academic ranking, years of experience, clinical work hours, training and board certification, core faculty status, position, and salaries. Results: As of September 2019, women account for only 12.7% of the total number of emergency physicians (EP) in Korea; of 119 chair/vice-chair academic positions, women represented only 9.2%. Women EP were more often assistant professors and fellowship-trained, with fewer in core faculty. However, they worked the same numbers of clinical hours as their men counterparts. The median annual salary of women EP was less than that of men EP after adjusting for academic hospital rank, clinical hours, and core faculty status. Conclusions: A gender gap still exists among Korean EP, and women earn less than men regardless of their rank, clinical hours, or training. Future studies should evaluate more data and develop system-wide practices to eliminate gender disparities.

A Nuclear Power Plant (NPP) is a complex dynamic system-of-systems with highly nonlinear behaviors. In order to control the plant operation under both normal and abnormal conditions, the different systems in NPPs (e.g., the reactor core components, primary and secondary coolant systems) are usually monitored continuously, resulting in very large amounts of data. This situation makes it possible to integrate relevant qualitative and quantitative knowledge with artificial intelligence techniques to provide faster and more accurate behavior predictions, leading to more rapid decisions, based on actual NPP operation data. Data-driven models (DDM) rely on artificial intelligence to learn autonomously based on patterns in data, and they represent alternatives to physics-based models that typically require significant computational resources and might not fully represent the actual operation conditions of an NPP. In this study, a feed-forward backpropagation artificial neural network (ANN) model was trained to simulate the interaction between the reactor core and the primary and secondary coolant systems in a pressurized water reactor. The transients used for model training included perturbations in reactivity, steam valve coefficient, reactor core inlet temperature, and steam generator inlet temperature. Uncertainties of the plant physical parameters and operating conditions were also incorporated in these transients. Eight training functions were adopted during the training stage to develop the most efficient network. The developed ANN model predictions were subsequently tested successfully considering different new transients. Overall, through prompt prediction of NPP behavior under different transients, the study aims at demonstrating the potential of artificial intelligence to empower rapid emergency response planning and risk mitigation strategies.

This paper is concerned with an algorithm based on neural networks to calculate the axial power distribution using excore defector signals in the nuclear reactor core. The fundamental basis of the algorithm is that the detector response can be fairly accurately estimated using computational codes. In other words, the training set, which represents relationship between detector signals and axial power distributions, for the neural network can be obtained through calculations instead of measurements. Application of the new method to the Yonggwang nuclear power plant unit 3 (YGN-3) shows that it is superior to the current algorithm in place.

Each 3D visualization program has its own different structure as for the purpose. This paper describes the design and development of an on-line 3D core data visualization program, $RocDis^{TM}$, for the nuclear simulator. It is possible to analyze the inside of the core status including neutron flux, relative power, moderator and fuel temperature in 3D distribution. Some of other essential information, axial flux distribution etc. could also display in 2D graphs. This program would be design, tuning and training for the simulator core model.

Recently, competition in the interior remodeling business is fierce. However, the interior remodeling business is basically B2B, and in this business, sales are basically dictated by the capabilities of salespeople. Therefore, in this study, we intend to develop a model for the core competency of salespeople in the interior remodeling business. To this end, based on the research on the existing competency and competency modeling, the competency model of the salesperson was derived using Dubois' overlay method. A total of 12 core competencies could be defined through the first and second modeling. The subject of this study was focused on LG Hausys, the most representative interior remodeling company in Korea. Based on the core competencies developed in this way, overall sales competencies can be raised through the development of a training course to enhance the sales competencies of salespeople, and a more efficient and objective HR.

Purpose: Clinical training for nursing students is limited to rudimentary skills to avoid potential risks. Simulation-Based Training (SBT) can overcome the shortcomings of clinical training. We evaluated the educational effect of SBT for obstetrical nursing students using high-fidelity simulation courses. Methods: We developed a simulation program for obstetrical nursing students to practice nursing skills that are necessary to provide quality care. The program consisted of four sessions. 1st: An orientation and a preliminary test. 2nd: Learning core skills required in obstetrical nursing. 3rd: Testing each student with scenario. 4th: Providing a debriefing session. At the beginning of the program, students were surveyed about their self-confidence in obstetrical nursing care, and at the end of the program, they were surveyed about the adequacy of SBT as well as self-confidence. Results: Students' self-confidence showed a significant difference before and after simulation. Mean adequacy of SBT was $7.15{\pm}1.35$ (out of 10). Most students became more interested in Women's Health Nursing after SBT. Conclusion: The results from evaluating the effects of simulation-based obstetrical nursing training show that SBT provides invaluable clinical experience for obstetrical nursing students by overcoming the lack of actual clinical involvement in clinical training programs.

Proper pre-safety training is one of core mandatory in order to reduce injuries at the construction fields. In this study, we investigate the employee's opinions of safety training, safety recognition, the actual conditions of safety through survey. As a result of study, incident factors are roughly divided into technical factor, managerial factor, and educational factor. We confirmed that the educational factor led by deficiency of safety awareness and knowledge was the major factor. It needs to be resettled or revised properly to match with the incident trends and the safety training curriculum should also be improved and drastically revised with special quality. The managerial workers' safety recognition is lower than the site ones regarding the correct understanding of the importance of the training.. It suggest that the education method and system in construction fields might have fundamental problems.
