노승덕,이근호,박철승 한국특수체육학회 2022 한국특수체육학회지 Vol.30 No.2
The purpose of this study is to understand the improvement factors of non-face-to-face physical education classes in day care center used by adults with developmental disabilities in the COVID-19 era. Accordingly, in-depth interviews were conducted with 5 sports instructors for the disabled who are working at the G sports association for the disabled. Data collection was conducted from August 2021 to February 2022, and a triangulation method such as content review of research participants and expert meetings was implemented to secure the trustworthiness of the research. For the analysis of the collected data, the topics were selected as ‘problems of non-face-to-face physical education classes’, ‘contents of online classes in day care facilities for the disabled’, and ‘plans to improve online classes’ through an inductive content analysis method. The results of this study are as follows. First, the problems of non-face-to-face physical education classes were difficulty in online class preparation process, difficulty in online class process, and poor exercise environment in daycare center for the disabled. Second, the contents of online physical education classes at daycare center for the disabled were customized classes through program transformation and online cooperative classes with daycare center managers. Third, It was found that expansion of equipment and facilities for online classes, preparation of sports instructors for the disabled and manpower support system, establishment of an online physical education system for the disabled were found to be necessary to improve online physical education classes. Based on these results, in order to activate non-face-to-face physical education classes in daycare center for the disabled, improvement of the online physical education class environment, capability development of sports instructors for the disabled and cooperation with the manger in charge of daycare center, and preparation of an online physical education system for the disabled is presumed to be necessary. 본 연구는 코로나19 상황에서 성인 발달장애인들이 이용하는 주간보호시설에서의 비대면 체육수업의 개선 요인을 이해하는데 그 목적이 있다. 이를 위해 G장애인체육회에서 근무하고 있는 장애인스포츠지도사 5명을 대상으로 심층면담을 실시하였다. 자료 수집은 2021년 8월부터 2022년 2월까지 진행하였으며, 연구의 진실성을 확보하기 위해 연구 참여자의 내용검토, 전문가회의 등 삼각검증법을 시행하였다. 수집된 자료의 분석은 귀납적 내용분석 방법을 통해 ‘비대면 체육 수업의 문제점’, ‘장애인주간보호시설에서 온라인 수업내용’, ‘온라인 수업 개선방안’으로 주제를 선정하였다. 연구 결과는 첫째, 비대면 체육 수업의 문제점은 ‘온라인 수업 준비과정의 어려움’, ‘온라인 수업 진행과정 어려움’, ‘장애인주간보호시설의 열악한 운동환경’으로 나타났다. 둘째, 장애인주간보호시설에서 온라인 체육수업 내용은 ‘프로그램 변형을 통한 맞춤형 수업’, ‘시설 담당자와 온라인 협력수업’으로 나타났다. 셋째, 온라인 체육수업 개선방안으로 ‘온라인 수업을 위한 장비 및 시설 확충’, ‘지도자의 역량 및 인력지원 체계 마련’, ‘장애인을 위한 온라인 시스템 구축’이 필요한 것으로 나타났다. 이 결과로 보아 장애인 주간보호시설의 비대면 체육수업을 활성화를 위해서는 온라인 체육수업 환경의 개선, 지도자 역량 및 주간보호시설 담당자와의 협력, 장애인을 위한 온라인 체육수업 시스템이 마련되어야 할 것으로 사료된다.

In the 3-phase PWM converter, accurate detection of the supplied voltage phase is very important. But a detecting circuit cannot avoid generating the deviation of phase detector so that we need to compensate it. In this paper, an accurate and simple compensating method of deviation of phase detector is proposed.

This paper is a study to apply EPPR valve for the electronic control of variable displacement hydraulic piston pump. In order to adjust the displacement of the pump, a regulator capable of controlling the swash plate angle is required. I apply the EPPR valve which is a valve that controls the output pressure by proportional current. It can be applied to control the swash plate angle with the advantage of excellent response, competitive price and electronic control. So this study deals with the development of analytical model and analysis of characteristics of EPPR valve by using SimulationX.

This study deals with the development of independent driving hydraulic system for disaster correspondence in which there is no development case in Korea. The development target is a system in which four traveling motors are driven independently, and it should easy to operate even under the condition that load is applied to the traveling motor differently. In order to be suitable for complex work, the hydraulic system was designed using the main control valve with pressure compensation function. If we can develop an analytical model that reflects the specifications and functions of the parts through the analysis program, we can verify the validity of the design before you make the prototype. In other words, the purpose of this study is to examine the feasibility of designing an independent drive hydraulic system through the development of an analysis model from the viewpoint of complex work. The analysis program uses Simulation X.
