This paper describes the development of a pc-based machinery space simulator for training and research, relevant to STCW-95. The detailed mathematical modelling process for the actual machinery is discussed and a method to perform effective education and training for the simulator is suggested. The method includes scenario, procedure, exercise and evaluation. The procedure guides the trainee through a sequence of steps designed to meet a specific goal, showing the trainee what must be done and explaining why The exercise enhances understanding for efficient engine management and enable user to perform research for the machinery. The evaluation shows exercise results and feeds back to instructor how to guide the under-performed trainee.

Today Human Personal Trainers are becoming very famous in this health conscious world. They teach user to achieve fitness goals in managed way. Due to their high fee and tight schedule they are unavailable to mass number of people. Another solution to this problem is to develop digital personal trainer portable instrument that may replace human personal trainers. We developed a portable digital exercise trainer device - BIOFIT that manages, monitors and records the user's physical status and workout during exercise session. It guides the user to exercise efficiently for specific fitness goal. It keeps the full exercise program i.e. exercises start date and time, duration, mode, control parameter, intensity in its memory which helps the user in managing his exercise. Exercise program can be downloaded from the internet. During exercise it continuously monitors the user's physiological parameters: heart rate, number of steps walked, and energy consumed. If these parameters do not range within prescribed target zone, the BIOFIT will alarm the user as a feedback to control exercise. The BIOFIT displays these parameters on graphic LCD. During exercise it continuously records the heart rate and number of steps walked every 10 seconds along with exercise date and time. This stored information can be used as treatment for the user by an exercise expert. Real-time ECG monitoring can be viewed wirelessly (RF Communication) on a remote PC.

Purpose: Changes in eating habits and malnutrition due to dysphagia are important health problems for older adults. This study investigated the effects of an educational program aimed at improving diet quality in community-dwelling older adults at risk for dysphagia in South Korea. Methods: We assessed 27 individuals in the experimental group and 26 individuals in the control group between September and October 2015. All participants were aged 65 years or older and were at risk for dysphagia. A combined diet and exercise program was applied to the experimental group (n = 27) for six weeks. We examined changes in participants' eating habits and their knowledge and attitudes concerning dysphagia risk. The nutrition intake of all participants was measured before and after the intervention using 24-hr dietary recall. Results: There was a significant increase in knowledge of dysphagia risk in the experimental group, with scores increasing from 3.7 to 7.1, out of 10 points (p < 0.001). There were also significant improvements in eating habits after the intervention in the experimental group, with scores increasing from 21.9 to 28.3, out of 36 points (p < 0.001). The attitude score of participants in the experimental group increased significantly, from 15.2 to 16.7, out of 20 points (p = 0.016). Conclusion: Developing educational programs can help older adults living in the community lead a healthier lifestyle and improve their ability to manage their diet.

Objectives: Weight counseling is an inevitable process for patients with obesity who intend to lose weight; however, the contents of real-world counseling practices remain uncertain in Korean medicine (KM) practice. This study aimed to explore the structure and constituents of obesity counseling in KM. Methods: Qualitative methods were used to explore the structure of weight counseling and clinicians' approaches to weight counseling, particularly the advice and main constituents of weight counseling in KM. Nine KM clinicians (4 women, 5 men) from nine clinics completed face-to-face, individual and semi-structured interviews from September 2019 to February 2020 in Seoul, Daejeon, Cheonan, Seongnam, Asan, and Hwaseoug. The interviews were digitally recorded, transcribed verbatim, and categorized based on their constituents. Results: During weight loss counseling, the six principal constituents of KM identified were: planning with patients, motivation, correcting misinformation on weight loss, dietary and exercise advice, medication guidance, and customized guides for each type. Conclusion: Clinicians with in-depth knowledge about obesity prescribed personalized guidance for exercise, diet, and medication through an integrative approach. The study results provide an in-depth understanding of weight counseling in KM. These six constituents could guide the counseling provided by clinicians in obesity care.

Objectives As children are physiologically and pathologically sensitive and likely to have trouble developing respiratory and the digestive system, it is necessary for them to improve and adapt to their digestive and respiratory capacity slowly. Although they desperately need to practice Healthcare Qi Gong as they get older, few studies have been conducted about that. While collecting materials on child Healthcare Qi Gong, In order to study more about Dan Dong Ten Lessons, medical researchers and children's parent should be more concerned to these studies. The purpose of this study was to understand Dan Dong Ten Lessons through research on children's healthcare Qi Gong. Methods This study was prepared through collecting data from past oriental medicine studies. Through the examination of Chinese medicine books and scientific studies about Dan Dong Ten Lessons and healthcare Qi Gong, Dan Dong Ten Lessons was classified and systemized. Results Dan Dong Exercise among the contents of children's healthcare Qi Gong was classified through the classification and theorization of Dan Dong Ten Lessons, although the classification and development of children's Qi Gong methods should have been carried out in the area of korean medicine, but it was not easy to find the references. Conclusions Dan Dong Ten Lessons is a song and Qi Gong therapy for children. It also teaches children how to live their life, guides them in the right direction for their life. Therefore, it should be developed academically and practically, so that it can pass down to the next generation as traditional heritage.

Background: Korea Atomic Energy Research Institute (KAERI) operates several nuclear research facilities licensed by Nuclear Safety and Security Commission (NSSC). The emergency preparedness requirements, GSR Part 7, by International Atomic Energy Agency (IAEA) request protection strategy based on the hazard assessment that is not applied in Korea. Materials and Methods: In developing the protection strategy, it is important to consider an accident scenario and its consequence. KAERI has tried the hazard assessment based on a hypothesis accident scenario for the major nuclear facilities. During the assessment, the safety analysis report of the related facilities was reviewed, the simulation using MELCOR, MACCS2 code was implemented based on a considered accident scenario of each facility, and the international guidance was considered. Results and Discussion: The results of the optimized protective actions were 300 m evacuation and 800 m sheltering for the High-Flux Advanced Neutron Application Reactor (HANARO), the evacuation to radius 50 m, the sheltering 400 m for post-irradiation examination facility (PIEF), 100 m evacuation or sheltering for HANARO fuel fabrication plant (HFFP) facility. Conclusion: The results of the optimized protective actions and its distances for the KAERI facilities for the maximum postulated accidents were considered in establishing the emergency plan and procedures and implementing an emergency exercise for the KAERI facilities.
