This paper suggests an input device that allows a user not only to naturally interact with education contents in virtual environment but also to sense haptic feedback according to his/her interaction. The proposed system measures a user's motion and then creates haptic feedback based on the measured position. To create haptic information in response to a user's interaction with educational contents in virtual environment, we develop a motion input device which consists of a motion controller, a haptic actuator, a wireless communication module, and a motion sensor. To measure a user's motion input, an accelerometer is used as the motion sensor. The experiment shows that the proposed system creates continuous haptic sensation without any jerky motion or vibration.

Balance can be defined as the ability to maintain the body's center of gravity within the base of support with minimal sway. Falls occur frequently in the elderly persons by the physiological change and dysfunction with age. Injuries resulting from falls include soft tissue damage and fractures of the radius, humerus, and femoral neck other consequences of falls include decreased mobility, reduced confidence, long lies (which can give rise to hypothermia, dehydration and pneumonia), and death Risk factors for falls have beau classified as intrinsic (those related to the individual) and extrinsic(those associated with environmental features), Intrinsic factors include decreased strength, visual deficits, vestibular dysfunction, and decreased vibratory sensation in the feet. Improvement of the balance related to the increased probability for fells in the elderly persons and is important for fall preventions and improvement of the living quality ef the elderly persons

Purpose : This study aims to identify changes in the visuomotor coordination and fine motor coordination functions caused by the use of a task-oriented intervention in a child with developmental delay. Methods : The participant, who was a 6-year-old girl, was not diagnosed but showed a developmental delay in overall function. The study period was February 5, 2021, to June 4, 2021, and a single-subject A-B study design was used. The baseline (A) was initially evaluated in the first three sessions to identify the child's functions. In the intervention period, 12 session (B), task-oriented intervention was applied; the child engaged in many of the activities in kindergarten, such as painting, writing, making, and cutting with scissors. Visuomotor coordination and fine motor coordination were equally measured during the baseline and intervention periods. Visuomotor coordination was measured via drawing of an oval according to the Korean Developmental Test of Visual Perception 3 (K-DTVP-3), and fine motor coordination was assessed using the finger-nose touching item of the Clinical Observation of Motor and Postural Skills (COMPS). Results : The mean of the baseline of the K-DTVP-3 oval drawing was 23, and the mean of the intervention period was 39.66. The mean of the baseline of the COMPS finger-nose touching was 0, and the mean of the intervention period was 5.08. Conclusion : Task-oriented intervention seems to have a positive effect on the visuomotor coordination and fine motor coordination abilities of children with developmental delay.

A science museum responds independently based on the exhibits and exhibition environments as the visitors are different in purposes, interests and demands. Therefore a science museum should be designed keeping it in mind that there are various ways for visitors to perceive and use the exhibition spaces and exhibits. The purpose of this study is to compare and analyze the characteristics of sensory receptors for the exhibits in National Museum of Nature and Science's Global Gallery, Tokyo, in terms of information transmission and to identify the nature of exhibit medium that can affect the perception and recognition of the exhibits by visitors. Through these 9 sensory receptors, human recognizes first with visual, auditory and olfactory senses and reacts using vestibular organ, proprioceptor (stretch), tangoreceptor, themoreceptor, taste and olfactory senses. Human uses these information processing to recolonize the external environment. This process is similar to the visitor's information transmission process for the exhibition medium. By dividing the analysis results per exhibition theme and developing the information transmission processing types per sensory receptor, we could understand that the distribution conditions are closely connected with the composition of the exhibition scenario in the exhibtion area. Especially, the understanding of how the information transmission is made through sensory receptors could can be the criteria that determines on the factors that can identify the exhibition purposes of a science museum which are eduction and understanding.

This paper deals with the process of estimating the environmental noise generated from the actual flying aircraft using the noise measurement results obtained through the wind tunnel test and verifying it through flight tests. In order to evaluate the environmental noise of an aircraft, noise tests and evaluations are generally conducted according to the procedures prescribed by the International Civil Aviation Organization (ICAO). In this paper, we introduced environmental noise evaluation method that can be applied to composite both fixed-wing aircraft and multi-copter, and introduced the evaluation method by experiment. This paper introduces the process of simulating the noise test results measured in the wind tunnel test using real flight test results. In addition, in consideration of flight operating conditions and noise measurement methods proposed by the ICAO, the effective perceived noise level (EPNL) was predicted by performing both the wind tunnel test and the aircraft flight test.

Yuri Vasilyev - actor, director and drama teacher. Russian meritorious artist, winner of the stage "Medal of Friendship" awarded by Russian President Vladimir Putin; academician of the Petrovsky Academy of Sciences and Arts in Russia, professor of the Russian National Academy of Performing Arts, and professor of the Bavarian Academy of Drama in Munich, Germany. The physiological sense stimulation method based on the improvement of voice, language and motor function of drama actors. On the basis of a systematic understanding of performing arts, Yuri Vasiliev created a unique training method of speech expression and skills. From the complicated art training, we find out the most critical skills for focused training, which we call basic skills training. Throughout the whole training process, Professor Yuri made a clear request for the actor's lines: "action! This is the basis of actors' creation. So action is the key! Action and voice are closely linked. Actor's voice is human voice, human life, human feeling, human experience and disaster. It is also the foundation of creation that actors acquire their own voice. What we are engaged in is pronunciation, breathing, tone and intonation, speed and rhythm, expressiveness, sincerity, stage voice and movement, gesture, all of which are used to train the voice of actors according to the standard of drama. In short, Professor Yuri's training course is not only the training of stage performance and skills, but also contains a rich view of drama and performance. I think, in addition to learning from the means and methods of training, it is more important for us to understand the starting point and training objectives of Professor Yuri's use of these exercises.

Ixodes signatus nymphs were subjected to the scanning electron microscopy for the observation of the major physiological sense organs including the Hailer's organ. Finger prints and variable sensory setae were found on the body surface, and especially well developed setae were identified on the article IV and on the anal lobes. A central button-like organelle and numerous small holes were found in the spiracular plate. The Haller's organ was identified at the distal point of the tarsus I and regarded as the major sensory organ, chemoreceptor. Tow types of sensory setae were observed, the shorter ones in front of the organ and the longer ones in distal front as well as near behind of the organ. The fully opened organ was ellipsoidal and a total of seven basiconic sensory pegs rooted deeply and shaped as well arranged hook-like was found inside the organ.
