When a doctor examines a patient in a hospital, the doctor directly checks the patient's condition and conducts a face-to-face diagnosis through dialogue with the patient. However, it is often difficult for doctors to directly treat patients. Recently, several types of telemedicine systems have been developed. However, the systems have lack of capabilities to observe heart disease, neck condition, skin condition, inside ear condition, etc. To solve this problem, in this paper, an interactive telemedicine robot system with autonomous driving in a room capable of visual examination and auscultation of patients is developed. The developed robot can be controlled remotely through the WebRTC platform to move toward the patient and check a patient's condition under the doctor's observation using the multi-joint robot arm. The video information, audio information, patient's heart sound, and other data obtained remotely from patients can be transmitted to a doctor through the web RTC platform. The developed system can be applied to the various places where doctors are not possible to attend.

The purpose of this study was to investigate the effects of a tactile-oriented sensory-motor developmental program on the visual attention and stereotypical behavior of an adolescent with intellectual disability. The subject was an adolescent with intellectual disability attending a special school located in B-gun, A-province of South Korea, with whom an A-B-A' design individual target study was conducted between August 27 and December 12, 2018. The intervention consisted of twelve 40-minute sessions, which were provided twice a week. For every session, two types of evaluation were conducted: a test that required staring at objects for visual attention, as well as an observation record for identifying the frequency and duration of stereotypical behavior. The results of this study showed that the tactile-oriented sensory-motor developmental program had positive effects on the duration of the participant's ability to stare at objects and the frequency and duration of stereotypical behavior. As this study confirmed and usefulness of this tactile-oriented sensory-motor developmental program as an intervention for improving the visual attention, and stereotypical behavior of adolescent with intellectual disabilities, the program may be employed to help members of this groups who have problems with sensory processing.

To obtain visual information of a target object, a camera should be placed within the visibility region. As the visibility region is dependent on the relative position of the target object and the surrounding object, the position change of the surrounding object during a task requires recalculation of the visibility region. For a fast computation of the visibility region so as to modify the camera position to be located within the visibility region, we propose a spherical projection method. After being projected onto the sphere the visibility region is represented in $\theta$-$\psi$ spaces of the spherical coordinates. The reduction of calculation space enables a fast modification of the camera location according to the motion of the surrounding objects so that the continuous observation of the target object during the task is possible.

When reinforced concrete is subjected to high temperature as in fire, there is deterioration in its properties of particular importance are loss in compressive strength, cracking and spalling of concrete, destruction of the bond between the cement paste and the aggregates and the gradual deterioration of the hardend cement paste. Assessment of fire-damaged concrete usually starts with visual observation of color change, cracking and spalling of the surface. In this paper, it was reported the trends of research and practical use on the Explosive Spalling Properties of the High-Strength Concrete.

In astronomical observations, stable auto-guiding and accurate target centering capabilities are critical to increase observation efficiency and sensitivity. Recently, Center for the Exploration of the Origin of the Universe (CEOU) has developed SQUEAN (SED camera for QUasars in EArly uNiverse). SQUEAN is installed and had successful observations at the 82 inch Otto Struve Telescope of McDonald Observatory in 2015 February. We have upgraded the existing auto-guiding softwares to KAP82 (KHU Auto-guiding Package for the McDonald 82 inch Telescope). Keeping the original hardware systems and the software algorithms of CAP (CQUEAN Auto-guiding Package), KAP 82 is completely re-written in Visual C++. We developed several center finding algorithms, e.g., 2D-gaussian fitting and weighted mean methods. In this presentation, we compare the auto-guiding performances with these algorithms.

Experimental study was conducted to investigate the effects of axial forcing on the flame structures near the nozzle exit of non-premixed flame. The most notable observation is that the direction of vortical motions is changed at some ranges, according to the increase of excitation amplitude. Especially, the elongation flame and the phenomenon of In-burning are always occurred when the vortical motion turnabout. In an analysis of the flame/flow visualization by means of direct photography and RMS technique, a plausible explanation can be made that above phenomena are related only to the amplitude of phase average velocity between the instantaneous velocity elements of excited flow.

Objectives : This study is a clinical report about 19-year-old male patient with Duodenal ulcer. Methods : The patient was treated by acupuncture, herb medication. The improvement of the symtoms was evaluated by Visual Analog Scale(VAS), Endoscopy. Results : Brash was gradually reduced and dyspepsia got improved. Conclusions : Oriental medical treatment was effective to improve duodenal ulcer. There should be more observation about patients with duodenal ulcer.

The purpose of this study is to examine how Korean changed and applied the railway official residence space constructed by the Japanese, when they occupied these railway official residence space after liberation from Japan, and specify the relationship between the life culture and residence space by analysing the differance in important life style, as well as element of change in important residence spaces according to modernization. In addition, this study was carried out by means of research on the form and pattern, visual anthropological method by photograph and direct observation.The result of this study is summarized as fellows. The residence space at Kyounaju constructed by the Japanese on the basis of the culture has been changed and applied to the life style of the Korean when the Korean occupied these Japanese style residence space.Then, it seems that the change of the Japanese style residence was caused by both differance in the life pattern between Korea and Japan, and the medernization of the life.

The purpose of this study is to analyze the original plans of the Railway official residence and process of the transfiguration of those plans based on the transition of social-culture, using 54 houses which were built from 1920 to 1945 in Taegu-Kyoungbuk province. In addition, this study was carried out by means of research on the form and pattern, and visual anthropological method by photograph and direct observation. The results of this study are as follows : 1) The original plans of Railway official residences were composed of the entrance hall, TADAMI Rooms, bathroom, toilet and HUSMA(wooden sliding doors). 2) After 1945, the room, kitchen, toilet of Japanese style had been trasfiguerated to Korean traditional style. 3) Since 1980's, those of Korean traditional style has been trasfigurated to the livingroom, dinningroom, entrance hall and etc. of western style.

In this study, the field applicability on reducing the heat of hydration of mass concrete by using the hydration heat difference method is analyzed with the following summary. As a result of applying the hydration heat difference method by using low heating combination, the temperature difference between the central part and the surface part of mass material was reduced, and as a result of visual observation, there was no showing of cracks by the hydration heat on the upper surface part. Therefore, the cracking index of the field to apply this method was shown to be approximately 1.57 with very little crack occurrence probability of less than 3%.
