In this paper, we propose an emotion messenger which recognizes face or hand gestures of a user using a WebCAM, converts recognized emotions (joy, anger, grief, happiness) to flash-cones, and transmits them to the counterpart. This messenger consists of face recognition module, hand gesture recognition module, and messenger module. In the face recognition module, it converts each region of the eye and the mouth to a binary image and recognizes wink, kiss, and yawn according to shape change of the eye and the mouth. In hand gesture recognition module, it recognizes gawi-bawi-bo according to the number of fingers it has recognized. In messenger module, it converts wink, kiss, and yawn recognized by the face recognition module and gawi-bawi-bo recognized by the hand gesture recognition module to flash-cones and transmits them to the counterpart. Through simulation, we confirmed that CPU share ratio of the emotion messenger is minimized. Moreover, with respect to recognition ratio, we show that the hand gesture recognition module performs better than the face recognition module.

In this paper, we describe methods that analyze a human gesture. A human interface(HI) system for analyzing gesture extracts the head and hand regions after taking image sequence of and operators continuous behavior using CCD cameras. As gestures are accomplished with operators head and hands motion, we extract the head and hand regions to analyze gestures and calculate geometrical information of extracted skin regions. The analysis of head motion is possible by obtaining the face direction. We assume that head is ellipsoid with 3D coordinates to locate the face features likes eyes, nose and mouth on its surface. If was know the center of feature points, the angle of the center in the ellipsoid is the direction of the face. The hand region obtained from preprocessing is able to include hands as well as arms. For extracting only the hand region from preprocessing, we should find the wrist line to divide the hand and arm regions. After distinguishing the hand region by the wrist line, we model the hand region as an ellipse for the analysis of hand data. Also, the finger part is represented as a long and narrow shape. We extract hand information such as size, position, and shape.

Objectives : This study was conducted to examine the educational status and needs of both parents and kindergarten teachers pertaining to the prevention of infectious diseaes in children. Methods : The participants were 280 parents and 147 kindergarten teachers. Data were collected from August 21, 2013 to December 30, 2014. Results : Only 16.7% of parents had educational experience with infectious diseases. The source of their education was broadcast media and their preferred educational method was the internet. Parents reported that the childhood infection about which they should be educated were influenza (30.4%) followed by hand-foot-and-mouth disease (13.9%), food poisoning (6.4%), and so on. About 27.2% of kindergarten teachers had received an education about infectious diseases, and the major source of their education was refresher training. The teachers' preferred educational method was the internet. The teachers wanted to be educated about influenza (22.4%), hand-foot-and-mouth disease (20.4%), food poisoning (20.4%) and so on. Conclusions : Educational programs should be developed and applied to children, parents and kindergarten teachers based on consideration of their educational needs.

In this paper, we propose a real-time interaction method using user's mouth wind in mobile device. In mobile and virtual reality, user interaction technology is important, but various user interface methods is still lacking. Most of the interaction technologies are hand touch screen touch or motion recognition. In this study, we propose an interface technology that can interact with real time using user's mouth wind. The direction of the wind is determined by using the angle and the position between the user and the mobile device, and the size of the wind is calculated by using the magnitude of user's mouth wind. To show the superiority of the proposed technique, we show the result of visualizing the flow of the vector field in real time by integrating the mouth-wind interface into the Navier-Stokes equations. We show the results of the paper on mobile devices, but can be applied in the Agumented reality(AR) and Virtual reality(VR) fields requiring interface technology.

Purpose: Temporomandibular disorder (TMD) is one of the most common diseases causing chronic orofacial pain. Prolotherapy is called 'regenerative injection therapy' or 'growth factor stimulation injection', and it induces the functional reactivation of tissues such as ligaments and tendons. The aim of this study is to evaluate the efficacy of ultrasound-guided prolotherapy with platelet-rich plasma (PRP) for the patients who had the TMD symptoms, especially in temporomandibular joint (TMJ) pain, restricted mouth opening, and TMJ sound. Methods: Twenty-seven patients visited Chosun University Dental Hospital with the symptoms of pain, restricted mouth opening, and TMJ sound were included in this study. When the patients visited the hospital, we measured; the degree of pain, range of mouth opening (ROM), and TMJ sound, and grouped them according to their chief complaints. TMJ pain and ROM were measured both at the first visit and the fourth week after the PRP injection, and also evaluated the impact of the treatment on their daily activities. Results: After the treatment, the patients in the TMJ pain group showed some improvement (visual analogue scale [VAS] 5.6 to 3.6), and the patients in the restricted mouth opening group exhibited increased ROM (26 mm to 32 mm; p<0.05). On the other hand, the patients in the TMJ sound group had no improvement. Conclusions: PRP prolotherapy could be effective for the treatment of TMJ pain and restricted mouth opening. However, further studies are still necessary in terms of TMJ sound and longterm effect of PRP prolotherapy.

The purpose of this study is to clarify the effect of mountain-valley wind on heat island formed in urban area which is located around valley mouth. The meteorological observations were carried out over the Dalbi-valley under a clear summer pressure patterns, and some consideration were tried from the results. In order to make clear the climatological characteristics and air-mass modification process of the mountain-valley wind over the valley, the meteorological observations were done simultaneously at two points. The observational points were located at the breast and valley mouth parts, respectively. The results were as follows: First, it was found that the valley wind was observed through the daytime, and it was replaced by a mountain wind after sunset. Second, the heat budget is also investigated with observation data. The sensible heat flux over the breast of Dalbi-valley reached to about $200 W/m^2$ during daytime, which is a little more than one third of net radiation. On the other hand, the sensible heat flux represented negative values during nighttime. But the sensible heat flux over the valley mouth covered by asphalt showed plus value(about $20{\sim}30 W/m^2$) during the nighttime.
