This paper, the integration of driving simulator and unmanned vehicle by means of new concept for better performance through a tele-operated system is suggested. But autonomous system is one of the most difficult research topics from the point of view of several constrains on mobility, speed of vehicle and lack of environmental information. In these days, however, many innovations on the vehicle provide the appropriate automatic control in vehicle subsystem for reducing human error. This tendency is toward to the unmanned vehicle or the tele-operated vehicle ultimately. This paper describes the motion system ...

Purpose: The COVID-19 pandemic has changed how healthcare is delivered worldwide and has affected the environment of the healthcare. Physical therapy in traditional healthcare systems can be difficult in unusual circumstances, such as the COVID-19 pandemic. Tele-physical therapy, defined as "the delivery of the physical therapy at a distance using electronic information and telecommunication technologies," will be a solution for this healthcare crisis. Thus, in this study, we proposed a mobile application for tele-physical therapy. Methods: This study used the Chrome Browser version 83.0.4 based on the Windows 10 64Bit operating system to use the App Inventor. To operate the mobile application, we used the Samsung Galaxy Note 9. The design of the mobile application was based on the review of a system used in the physical therapy department. Results: The graphical user interface (GUI) of the mobile application was displayed on three screens: selecting a painful joint (1st screen of the GUI); selecting a painful movement of the joint (2nd screen of the GUI); a self-manual therapy method and movie (3rd screen of the GUI). The proposed mobile application showed the stable repeatability of the self-manual therapy movie. Conclusion: The results of this study demonstrated that the proposed mobile application using the App Inventor for android will be able to create easy to use and reliable tele-physical therapy.

The necessity of a short period of software development with lower cost came out. The reason of making the component based development is that it can improve the software development , productivity maintenance , and software quality innovatively. Following these advantages of component based application development methods, we found the COM based components effective to Window platform in the satellite surveying. In this paper, we can obtain many precious engineering experiences. Software system development and maintenance will take much shorter time with higher reusability if satellite surveying system is constructed with component extraction proposed by us.

Objective : The COVID-19 pandemic has brought non-face-to-face healthcare service delivery system. Research into telehealth system and its efficacy remains unclear. Methods : Seven healthy adults participated in this study to investigate effects of tele-monitoring with the speech-to-text (STT) application to induce changes in occupational activities on occupational balance in healthy adults. Subjects were requested to choose occupational activities they wanted to have researched and then register them to the STT application. The STT application provided an alarm to check whether the pre-registered activities were performed on time, and whether the subjects performed it by their voice. The subjects were followed for 1 week, with assessments at baseline, and after 1-week's tele-monitoring. Results : Our findings showed that the subjects were willing to participate in tele-monitoring with the STT application with high adherence and satisfaction. In addition, there was a significant improvement in occupational activities related to health (p<.05). Specifically, adherence, satisfaction, and efficacy of the tele-monitoring with the STT application could successfully bring occupational balance in short-term periods. Conclusion : These findings highlight that tele-monitoring with a smartphone could be considered as one promising way to restore occupational balance in lockdown after the COVID-19 outbreak.

산업플랜트에는 고온 고압 배관 시스템을 갖춘 곳이 많으며, 이 배관 시스템의 건전성은 매우 중요하게 취급된다. 배관의 건전성 유지를 위해서는 일정 기간 동안 배관의 안정성 검사를 수행하게 되는데, 배관 시스템의 복잡성과 위험성으로 인한 검사자의 접근 자체가 매우 어려운 상황이 빈번하게 발생한다. 이를 해결하기 위하여 로봇 개술을 적용하는 연구개발이 지속되고 있는데 본 논문에서는 5축 대관절 매니퓰레이터 형태의 배관 등반이 가능한 반자동 원격 제어 로봇의 개발에 대하여 기술한다. 이 로봇의 구현을 위해서는 로봇의 배관 인지 기술, 로봇의 배관 그리핑 기술, 5축 관절의 제어 기술, 그리고 원격제어기술등이 요구된다.

본 논문에서는 원자력발전소와 같은 극한환경에서 사용할 수 있는 로봇 원격제어를 위한 데이터 송수신용 통신 모듈 구현의 제약 조건을 기술하고 이를 해결할 수 있는 방안을 제시한다. 원격제어는 오퍼레이터가 원격지 로봇의 다양한 환경 정보를 인식하면서 로봇 제어 명령을 전송하는 특성을 갖는다. 오퍼레이터와 원격지 로봇 사이에 지속적인 데이터 통신에 의해 제어를 수행하므로, 통신 속도와 통신 프로토콜에 따른 현재의 통신 상태 보장 방안도 필요하다. 네트워크 기반 통신에서는 물리적 환경에 의한 영향을 포함하여 TCP/IP 프로토콜의 경우 핸드쉐이크와 혼잡회피 알고리즘 등에 의한 논리적 통신 속도의 지터가 발생하므로, 로봇 원격제어 시 이 문제를 충분히 검토해야한다. 로봇 원격제어를 위해서는 TCP/IP는 물론 UDP와 같은 통신 프로토콜과 시리얼 통신 기반의 다양한 프로토콜을 적용할 수 있는데, 송수신 데이터의 종류에 따라 적절한 프로토콜을 적용해야하며 통신 라인의 연결 상태도 확인할 수 있어야 한다.

PURPOSE: This study examined the status and prospects of telerehabilitation to identify the challenges and propose strategies for its promotion both domestically and internationally. The study also focused on the preconditions and improvements required for adopting telerehabilitation, considering technological, institutional, and socio-cultural factors. METHODS: A thorough database search was conducted. The relevant research, papers, and reports were collected, and the literature was evaluated to summarize the findings. RESULTS: Tele-rehabilitation showed promise in enhancing the healthcare service quality and accessibility. However, addressing challenges requires a comprehensive analysis of its status, global research trends, and the formulation of adoption strategies. Research in this direction is expected to improve healthcare services. CONCLUSION: Tele-rehabilitation can enhance healthcare services by overcoming geographical limitations. On the other hand, addressing challenges through analysis and strategic planning is essential for its effective adoption and advancing healthcare quality and accessibility.

Purpose: This study was done to analyze the effects of tele-care case management services using secondary data. Methods: A descriptive research design was utilized, and the participants were 134 medical aid beneficiaries who were in either the high-risk group or the preventive group. Casemanagement services were delivered by 8 care managers. Data were analyzed using PAWS Statistics 17 through descriptive statistics and paired t-test. Results: After the case management intervention, the participants' health quality of life, self-care competency, and reasonable medical care utilization increased significantly for the high-risk group. However there were no significant changes in the preventive group. Conclusion: The results showed that the tele-care case management services were effective for high-risk medical aid beneficiaries. Further studies with controls for constitutional variables and a comparison group are required to validate the robustness of the effectiveness of the case management program in the present study.
