Most partial hand amputees experience limited wrist movement, which hinders the efficient functioning of upper limb, affecting hand-to-use coordination and the usability of the prosthetic hand. This limitation can lead to secondary musculoskeletal issues due to repetitive compensatory movement patterns. However, current partial hand prosthetic lack rotational wrist movement due to challenges in accommodating various hand shapes and limited space. In our study, we proposed a prosthetic hand with a wrist rotation module for partial hand amputees, aiming to reduce compensatory movement. To validate the proposed wrist rotation module, we conducted motion analysis during reach-to-grasp task. Furthermore, during the Jebsen-Taylor hand function test, we evaluated both the effect on upper limb movement and the usability of the prosthetic hand, comparing configurations with and without the wrist rotation module. The results showed that the prosthetic hand equipped with rotational wrist movements reduces compensatory movements and promotes efficient upper limb movement patterns. This finding highlights the value of incorporating a wrist rotation module in prosthetic hands to improve upper limb movement for partial hand amputees.

Our society is aging rapidly, and the number of elderly people who are in charge of purchasing and preparing foods at home is increasing. However, most the elderly have difficulty managing nutrition and food safety by themselves. The purpose of this study was to develop the necessary knowledge, through focus group interview and Delphi technique to establish a food safety and nutrition education program. The diet and educational needs of the elderly were surveyed through FGI. The education topics were decided by the Delphi technique. The education program consisted of a five week program, and the topics taught were 'Dietary Change for Healthy Life', 'Prevention of Food Poisoning in Everyday Life', 'Safe Food Handling for my Health', 'Healthy Dietary Life to Prevent Chronic Disease', and 'Safety! Nutrition! Healthy Dietary Life'. This education program was designed to decrease the perceived barriers, and to increase the perceived interests and the sense of self-efficacy. Education program materials, lesson plans, slides, handouts, videos, leaflets, and booklets were developed. Based on the results, the contents of the food safety guideline leaflets for the elderly were decided as the following: (1) wash your hands in the correct way; (2) select safe food; (3) cook foods safely; (4) keep foods safely; (5) keep kitchen utensils clean. In conclusion, if advanced education programs are implemented and delivered continuously in locations such as health centers and community welfare centers, those will contribute significantly to enhance the perception of food safety and to change the desirable dietary behavior of the elderly.

The purpose of this study was to investigate differences in the perception and attitudes of middle school students toward food safety between those who possess high behavioral intentions to prevent contracting a foodborne illness and those who do not. The survey collected 871 usable data from several middle schools in Seoul, Korea in July 2007. Using six behavioral intention measurement items, a two-step cluster analysis approach was conducted resulting in a strong intention group and a weak intention group. Perception and attitudes toward foods safety were different between the two groups. Students with strong behavioral intentions to prevent foodborne illness tended to possess a stronger perception and attitude toward various food safety issues. Students with strong intentions were more certain of consumer's right to purchase safe foods, more concerned about foodborne illness and food safety, believed that the government should put more efforts toward establishing a safe food chain, possess more distrust for food suppliers, were more aware of specific foodborne illness pathogens, had more food safety education/training, and washed their hands more frequently than those with less strong intentions. No significant differences were found between the groups but,overall, chemical residues and food additives were perceived as more harmful and more serious food safety issues than those of foodborne illness pathogens despite that microorganisms are the main cause of foodborne illness outbreaks in schools. Participants seemed to underestimate the importance of temperature control for preventing foodborne outbreaks. Several implications and suggestions on how to improve the behavioral intentions of middle school students to prevent possible foodborne illness were provided.

India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python. These tiny experiments are really helpful to encourage the students and give play way to learn these advance technologies. The cost estimation is presented in tabular form for per learning kit provided to the students for Hands on experiments. Some Popular In addition, some Open source tools for experimenting with IoT Technology are described. Students can enrich their knowledge by doing lots of experiments with these freely available software's and this low cost hardware in labs or learning kits provided to them.

Purpose: Due to the coronavirus infection-19 (COVID) pendemics, all educational institutions were required to provide full non-face-to-face real-time education, and fire officials were required to provide fire-fighting education by applying non-face-to-face education. In this difficult situation, the National Fire Service Academy tries to find the direction of the non-face-to-face real-time education and suggest ways to improve it through a survey of the status of non-face-to-face real-time education conducted by the NFSA to fire officials. Method: A survey was conducted on fire officials under the theme of "Consciousness Survey for Improving the Quality and Specialization of Non-face-to-face Real-Time Remote Education" and an in-depth analysis was conducted based on the results. Result & Conclusion: First, professors or educational operators shall actively utilize remote education programs suitable for educational characteristics by utilizing various programs. Second, a dedicated notebook for non-face-to-face training should be provided to provide an educational environment where all learners can participate in the training without difficulty. Third, in the case of education and training that requires the use of equipment due to the nature of fire officials' education and training, it is necessary to consider it as a non-face-to-face training place by arranging educational equipment at each fire station. Fourth, it is hard to expect a satisfactory educational effect to cope with practical education with theoretical education. Therefore, facilities and programs that enable non-face-to-face real-time hands-on training should be developed. It is worth considering the proper combination of face-to-face education while maintaining the social distance as much as possible until such non-face-to-face training is possible. Fifth, non-face-to-face education is considered to have high eye fatigue due to the light and electromagnetic waves of the computer screen, and as time goes by, the concentration level decreases. Therefore, it is necessary to form an education time to reduce the eye fatigue of learners and increase concentration through proper class and rest time. Finally, professors should operate a learner participation-oriented education that allows professors and learners to interact rather than one-sided knowledge transfer education. In addition, technical problems of non-face-to-face remote education should be thoroughly prepared through preliminary system checks to ensure that education is not disrupted.
