  • Class III malocclusion with mandibular protrusion can be divided into skeletal and pseudo malocclusion due to tooth displacement. For skeletal malocclusion, favorable treatment results can be obtained by establishing an appropriate vertical and horizontal intermaxillary relationship in order to secure a restoration space and obtain aesthetic and functional results. In this case, complete mouth rehabilitation was performed using an implant and a fixed prosthesis in a patient with mandibular protrusion and anterior teeth wear and reduced occlusal vertical dimension. After cast analysis and digital diagnosis, a provisional restoration with increased vertical dimension was fabricated to secure posterior support and evaluate stable centric occlusion. With the definitive prosthesis reflecting the provisional restoration, favorable function and aesthetics were obtained.

  • In this paper, we describe an image processing algorithm which is able to recognize the road lane. This algorithm performs to recognize the interrelation between AGV and the other vehicle. We experimented on AGV driving test with color CCD camera which is setup on the top of vehicle and acquires the digital signal. This paper is composed of two parts. One is image preprocessing part to measure the condition of the condition of the lane and vehicle. This finds the information of lines using RGB ratio cutting algorithm, the edge detection and Hough transform. The other obtains the situation of other vehicles using the image processing and viewport. At first, 2 dimension image information derived from vision sensor is interpreted to the 3 dimension information by the angle and position of the CCD camera. Through these processes, if vehicle knows the driving conditions which are lane angle, distance error and real position of other vehicles, we should calculate the reference steering angle.

  • The purpose of this study is to analysis children's measurement and to provide the fundamental information for he clothing design which can reflect the characteristic of their bodies. An anthropometric database used for this study was the 1992 national anthropomatric survey of Koreans. The results obtained are as follows; (1) Children showed the significant difference of their growth in accordance with the increase of their ages. There were also the difference between body and girls. Height, length of items grew most promthy. For example; boys from 10 to 11 and girls from 10 to 11 again their height mostly. (2) In character of body proportion, significant difference were found in accordance with their ages and sex. However, in the items of height, length noticeable changes of proportion could not be found because there were hardly any actual difference of size means while girth items appeared differently. (3) There were significant factors from the result of factor analysis of body dimension. The fist factor ; grith, depth, breath. The second factor ; height, length. (4) We can class three groups with the results of cluster analysis of body dimension.

  • Aberrant right subclavian arteries were experienced in two young children. This is a rare aortic arch anomaly that usually does not produce symptoms. Symtomatic patients require surgical interventions.We describe two young children who had aberrant right subclavian artery with symptoms of difficulty in swallowing and respiratory problems. Diagnosis was made by esophagography, aortography and 3-Dimension chest CT. Operation had been advocated through right thoracotomy without difficulty for ligation, division and anastomosis to the ascending aorta. Dysphagia lusoria was immediately relieved and postoperative course was uneventful. We consider that the right thoracotomy is the choice of operative approach and noninvasive diagnosis by 3-Dimension chest CT is easily made for infant with aberrant right subclavian artery.

  • This study develops and empirically tests a comprehensive model of consumers' brand page experiences that illuminates dynamics among perceived values (practical value, stimulation, enjoyment, and social identification), brand page engagement dimensions (cognitive engagement, affective engagement, and behavioral engagement) and brand loyalty. An online survey was employed for data collection. We collected 358 usable responses for data analysis. Structural equation modeling results show that three dimensions of perceived values (practical value, perceived enjoyment, and social identification) positively affect brand engagement dimensions, while perceived stimulation affects affective engagement only. As for the roles of brand page engagement, affective and behavioral engagement positively influence brand loyalty. This study demonstrates how consumers' perceived values of brand page experience influence each dimension of brand page engagement and how each dimension has a different impact on brand loyalty. The results of this study provide substantive contributions to the consumers' brand page experience and engagement literature and brand page management on social media for developing brand loyalty.
