운동 기구를 이용한 운동의 경우 바른 자세와 균형을 유지하는 것이 중요하다. 이에 본 논문에서는 적외선 감지센서가 부착된 디스플레이형 전신거울과 프리웨이트 운동기구에 부착된 센서를 이용하여 이용자의 정보를 인지하고 디스플레이 장치에 출력되는 가상 트레이너를 통해 균형 운동에 대한 가이드를 제공하는 게임형 콘텐츠를 설계하였다. 본 콘텐츠의 목표는 운동 시에 중요한 바른 자세를 잡기 위하여 균형 상태를 알 수 있게 하며, 가상트레이너에 의해 보다 효과적이고 흥미로우며 지속적인 운동을 가능하게 하는 방법을 제공하는 것에 있다.

Registration of the mandibular movement in patients with temporomandibular joint noise (clicking and/or crepitus) was performed using one of mandibular tracking devices(SAPHON VISI-TRAINER CII,Tokyo Shizai-sha Inc.,Japan). The obtained results were follows : 1. In many cases, the movement pattern of light emitting diode(LED) attached on the mandibular midline showed lateral deviation from a vertical reference line which was pronounced in association with TMJ noise during opening and closing. 2. In patients with unilateral TMJ noise the mandibular midline usually towards the side demonstrating TMJ noise during opening. 3. A distinct V-shaped discontinuity in the trace of velocity of mandibular movement was found at the point of the TMJ noise. 4. In patients with TMJ noise the velocity of mandibular movement at the point of the TMJ noise was decreased rapidly. 5. In several cases, TMJ noise could be eliminated by traning of Rocabado`s control of TMJ rotations.

We present a Taekwondo training system using a hybrid sensing technique of a body sensor and a visual sensor. Using a body sensor (accelerometer), rotational and inertial motion data are captured which are important for Taekwondo motion detection and evaluation. A visual sensor (camera) captures and records the sequential images of the performance. Motion chunk is proposed to structuralize Taekwondo motions and design HMM (Hidden Markov Model) for motion recognition. Trainees can evaluates their trial motions numerically by computing the distance to the standard motion performed by a trainer. For motion training video, the real-time video images captured by a camera is overlayed with a visualized body sensor data so that users can see how the rotational and inertial motion data flow.

Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation, cardiology skills, anaesthesia clinical skills, and crisis management. This will provide a brief overview of simulators and trainers in several domains.

Relaxed Static Stability (RSS) concept has been applied to improve aerodynamic performance of modern version supersonic jet fighter aircraft. The T-50 advanced supersonic trainer employs the RSS concept in order to improve the aerodynamic performance. And the flight control system stabilizes the unstable aircraft and provides adequate handling qualities. The T-50 longitudinal control laws employ a proportional-plus-integral type controller based on a dynamic inversion method. The longitudinal dynamic modes consist of short period with high frequency and phugoid mode with low frequency. The design goal of longitudinal control law is optimization of short period damping ratio and frequency using Lower Order Equivalent System (LOES) complying the requirement of MIL-F-8785C. This paper addresses phugoid mode characteristics such as damping ratio and natural frequency that is affected by the nonlinear control laws such as angle of attack limiter, auto pitch attitude command system and autopilot of pitch attitude hold.

In Korea, the regulation is MOLIT Notice 2018-290, Guidance for Approval of Synthetic Flight Trainer as Flight Simulator and Flight Training Device. The FAA (Federal Aviation Administration) categorizes FSTD (Flight Simulation Training Device) into FFS (Full Flight Simulator) and FTD (Flight Training Device), according to its level. Additional categories for regulation are airplane and helicopter, depending on the type of aircraft. In this study, the objective tests for the handling quality of the FAA and Korean regulations were compared and analyzed. In QPS (Qualification Performance Standard), related test titles, flight conditions, and tolerance limits were analyzed for the handling quality. Based on this study, recommendations on amendments to the regulation was presented.

In order to obtain the basic data of movements of the mandible for diagnosis and prgnosis determination of the TMJ dysfunction, the author measured the ranges and shapes of movements of the mandibule in the frontal, sagittal and horizontal trajectory with Saphon Visi-Trainer C-Ⅱ(Tokyo Shizaisha Inc.) in 61 men. The subjects who were undergraduate and graduate students of the School of Dentistry, Seoul Nationa University(SNU) had no pain or symptoms of dysfunction of the masticatory system. The obtained results were as follows: 1. The mean for maximal right and left laterotrusion in the frontal trajectory were 11.3 mm and 10.9mm, respectively and didn't differ significantly. Right and left larero-opening at 15mm, 25mm and 35mm mouth opening respectively didn't differ significantly. Area of border movement of the mandible was 770.33㎟. 2. The mean for maximal protrusion in the sagital trajectory was 10.2mm, antero-posterior deviation between ICP and RCP 1.2mm and angel of maximal protrusion and horizontal plane 20.5。. 3. The mean for right and left laterotrusion is 11.1mm &11.2mm,respectively, and didn't diffef significantly.

A model of an assessment module has been created, using intuitionistic fuzzy estimations, which render account on the knowledge of the trained objects. The final mark is determined on the basis of a set of evaluation units. An opportunity is offered no only fur tracing the changes of the parameters of the trainer object, but there is also an opportunity of tracing the status of the already comprehended knowledge, as well as evaluating and changing the training themes and evaluation criteria.
