In recent years, the developments in technologies, such as AI systems, Blockchain, VR/AR, 3D printing, robotics, and nanotechnology, are reshaping the future of healthcare right before our eyes. And also, healthcare has seen a paradigm shift towards prevention-oriented medicine, with a focus on consumers requirements. The spread of infectious diseases such as Covid-19 have altered the definition of healthcare and treatment facilities, necessitating immediate action to redesign hospitals' physical environments, adapt communication models to address social distancing requirements, implement virtual health solutions, and establish new clinical protocols. Hospitals, which have traditionally served as the hub of healthcare systems, are pursuing or being forced to reestablish themselves against this landscape. Rather than only treating ailments, future healthcare is predicted to focus on wellness and prevention. In personalized care, long-term prevention strategies, remote monitoring, early diagnosis, and detection are critical. Given the growing interest in smart healthcare defined by these modern technologies, this study looked into the definitions and service kinds of smart healthcare. The background and technical aspects of smart hospitals were also explored through a literature review.

Owing to the increasing demand for electric vehicles (EVs), appropriate management of their waste batteries is required urgently for scrapped vehicles or for addressing battery aging. With respect to technological developments, data-driven diagnosis of waste EV batteries and management technologies have drawn increasing attention. Moreover, robot-based automatic dismantling technologies, which are seemingly interesting, require industrial verifications and linkages with future battery-related database systems. Among these, it is critical to develop and disseminate various advanced battery diagnosis and assessment techniques to improve the efficiency and safety/environment of the recirculation of waste batteries. Incorporation of lithium-related chemical substances in the public pollutant release and transfer register (PRTR) database as well as in-depth risk assessment of gas emissions in waste EV battery combustion and their relevant fire safety are some of the necessary steps. Further research and development thus are needed for optimizing the lifecycle management of waste batteries from various aspects related to data-based diagnosis/classification/disassembly processes as well as reuse/recycling and final disposal. The idea here is that the data should contribute to clean design and manufacturing to reduce the environmental burden and facilitate reuse/recycling in future production of EV batteries. Such optimization should also consider the future technological and market trends.

In this paper, we discussed about the volume monitoring system of a landfill facility. We proposed the waste volume calculation method using the point cloud of the surface of three dimensional object by measurement of the point cloud by the three dimensional scanner, which is based upon the robot technique. This computes not only the quantity of waste volume for continuos monitoring but also it helps not only to predict the evaluation factor of the usable age of a landfill. facility. Furthermore, the measuring system of waste volume was applied to the landfill facility in Ansung city.

In the Core Technology R&D of the defence area, the development of the related core element technology could be the foundation to develop advanced weapon system in the future. But it might make various problems if you can not accurately define the TRL of the element technology. In other words, if the technology is not sufficiently mature and then the project starts, it might require an increase in the development period and additional cost. Finally the system will be in an incomplete state and result in user dissatisfaction and the project failure. Therefore it is a very important task to properly assess the TRL for a successful project. In this study, We propose the method for risk management of core technology R&D project of the defence area using the QFD process with degree of difficulty and technology readiness level. It is also presented the process to determine the risk level using TRL and Degree of difficulty. Finally We apply this method to UGV system for verifying the result of this study.

10년 후면 영어와 한국어가 실시간으로 자동 통역되는 통역기가등장하며, 컴퓨터의 키보드 나 마우스 등은 음성으로 대체되며, 인간과대화를 나누는 로봇이 등장하여 대부분의 인간 허드렛일을 대행 할 것으로 예상된다. 이러한 인공 지능형기기를 구현하기 위해서는 현재보다 1천배 이상의 성능을 보이는 즉, 테라급의 CPU와 메모리가 필요하다. 현재 반도체소자의 주류를 이루고 있는실리콘 트랜지스터는 무어 법칙에 따라 매18개월마다 2 배씩트랜지스터 집적도가 증가되어 왔으며 현재 32nm가 시장 출시를 앞두고 있으나 2016년 이후 22nm 이하는 특성 불균일/열 발생 과 같은 기술적 한계와 천문학적으로 늘어나는 칩 제조비용 때문에 제품 출시가 매우 어려울 것으로 여겨진다. 교육과학기술부는 이러한 한계 극복을 위해 21세기 Frontier 프로그램으로 테라급나노소자개발사업단을 2000년 7월 발족 하였으며 본 사업단은 테라급의 성능과 메모리 집적도를 갖는 나노소자개발을 최종목표로 출범 하였다. 프론티어사업은 10년 이상의 장기적인 개발기간이 필요한 'High Risk, High Return'의 특성을 갖고 있다. 본사업단은 이러한 프론티어사업의 취지에 따라 철저한 사전기획과 기술 환경변화에 따른 신속한 대응력, 철저한현장 중심적 사업관리를 해왔다. 본 재료학회 추계학술대회에서는 본 사업단이 이룩한 성과와 미래의 나노소자들을 소개할 예정이다.

In the previous study, a polishing robot system was developed to automate the polishing process and to cope with the shortage of skilled workers. This polishing robot system has several advantages: reduced time for setting polishing work, decreased labor costs, effective operation, continuous polishing work without an operator, improved machine accuracy, and the ability to polish a free curved surface die. However, still the problem remains that a worker must stay to monitor the polishing process in the poor working conditions for a long time. Nowadays some advanced manufacturing companies need to find a way to check the performance of their production equipments and plants from remote sites. Thus, this study constructed the communication network and developed the monitoring programs (a servo program and a client program) to operate the polishing robot from remote sites. Using these programs, workers are able to monitor and control the polishing robot on the web page, in any place where internet service is possible. To guarantee a stable operation in spite of a variable computer operating environment, the monitoring system is implemented in Java. The experimental results showed that the developed monitoring programs provided a stable communication.

The development of a prototype for a Bridge Transported Servo Manipulator (BTSM) system operating in a hot cell is introduced. Mechanical master-slave manipulators (MSMs) which are mounted on the hot cell wall cannot access all the areas for the equipment maintenance due to their reach limitation. The BTSM has been developed to overcome the limitation of access that is a drawback of the MSMs for the equipment maintenance. Wire driven mechanisms have been adopted to increase the handling capacity to weight. This system can be a useful reference for designing other devices in the nuclear industry.
