Objective: This study collected data on muscle fatigue and ground reaction force during walking to provide a basis for development of custom-fitted outdoor walking shoes. The study analyzed an upright body exercise program using spine stabilization technique to determine the effect on foot plantar pressure in archers, demonstrate the effectiveness of upright body exercise, and develop a new, effective, and efficient training program. Method: A 12-week upright body exercise program was evaluated for the effect on plantar pressure in archers. Ten prize-winning archers (3 men, 7 women) in B metropolitan city, each with ${\geq}10years$ of experience, were given an explanation of the content and purpose of the program, and provided informed consent. Upright body exercise was performed 3 times a week for 12 weeks. A resistive pressure sensor was used to measure foot plantar pressure distribution and analyze quantitative information on variation in postural stability and weight shifting in dynamic balance during shooting, as well as plantar pressure in static balance with the eyes open and closed. Results: There were no significant differences in foot plantar pressure before and after participation in the exercise program. There was no statistically significant difference in foot plantar pressure in static balance with the eyes open or closed, or in foot plantar pressure in dynamic balance during shooting. Conclusion: An upright body exercise program had positive effects on foot plantar pressure in static and dynamic balance in archers by reducing body sway and physical imbalance during shooting and with eyes closed. This program is expected to help archers improve their posture and psychological state, and thereby improve performance.

Recently, nations around the world are putting various efforts in many aspects to decrease greenhouse gases and international cooperation is urgently required. As part of these efforts, the shipping industry is working towords establishing "green parts" that reduce the carbon content of the greenhouse gases emitted in ports and can also decrease the operating costs. This study has tried to look for how to supply shore power instead of suppling ship's own generated power as a basic researches for reduction of carbon emissions and construction of "green parts" system. And in this paper, the training ship 'SAENURI' of Mokpo Maritime University under actual operation was selected to investigate for environmental and expense effects. The results of this study showed that $CO_2$ emissions Mere reduced 34% and operating costs Mere reduced approximately 31% in case of using the shore paper.

Background: Organizational changes that involve healthcare hospital departments and care services of health districts, and ongoing technological innovations and developments in society increasingly expose healthcare workers (HCWs) to work-related stress (WRS). Minimizing occupational exposure to stress requires effective risk stress assessment and management programs. Methods: The authors conducted an integrated analysis of stress sentinel indicators, an integrated analysis of objective stress factors of occupational context and content areas, and an integrated analysis between nurses and physicians of hospital departments and care services of health districts in accordance with a multidimensional validated tool developed in Italy by the National Network for the Prevention of Work-Related Psychosocial Disorders. The purpose of this retrospective observational study was to detect and analyze in different work settings the level of WRS resulting from organizational changes implemented by hospital healthcare departments and care services of health districts in a sample of their employees. Results: The findings of the study showed that hospital HCWs seemed to incur a medium level risk of WRS that was principally the result of work context factors. The implementation of improvement interventions focused on team development, safety training programs, and adopting an ethics code for HCWs, and it effectively and significantly reduced the level of WRS risk in the workplace. Conclusion: In this study HCW resulted to be exposed to occupational stress factors susceptible to reduction. Stress management programs aimed to improve work context factors associated with occupational stress are required to minimize the impact of WRS on workers.

In this paper, we propose a system to extract effective speaker representations from a speech signal using a deep learning method. Based on the fact that speech signal contains identity unrelated information such as text content, emotion, background noise, and so on, we perform a training such that the extracted features only represent speaker-related information but do not represent speaker-unrelated information. Specifically, we propose an auto-encoder based disentanglement method that outputs both speaker-related and speaker-unrelated embeddings using effective loss functions. To further improve the reconstruction performance in the decoding process, we also introduce a discriminator popularly used in Generative Adversarial Network (GAN) structure. Since improving the decoding capability is helpful for preserving speaker information and disentanglement, it results in the improvement of speaker verification performance. Experimental results demonstrate the effectiveness of our proposed method by improving Equal Error Rate (EER) on benchmark dataset, Voxceleb1.

E-Learning, a technology-based learning process is the obtaining of knowledge from the basis of IT technology. The development of e-Learning requires corporate educational staff as well as HR staff, who manage e-learning, to drastically change their roles. The main reason for this is that the properly adapted and highly experienced education and training abilities of HR staff could accelerate the adoption and usage of e-Learning but they need to clearly select and define an appropriate curriculum from among the extensive mass-customized content with an e-learning basis. Here the research has analyzed the influence of the introduction and usage of e-Learning in hotels on HR staff and their roles from the viewpoint of hermeneutic phenomenology.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.
