This research has an objective of investigating the challenges that student teachers encounter during practicum, the difference between teachers' image based on sociodemographic variables, recognition and satisfaction for practicum, and the effect of teachers' image and practicum experience on the satisfaction for the practicum. The participants of this study included 500 student teachers who enrolled in the department of early childhood education in a 2 or 3-year college or a 4-year university and completed practicum in the Chungcheong area. The instruments for this study were Teacher's Image Scale, Practicum Experience Scale, Practicum Satisfaction Scale and a questionnaire for sociodemographic variables. The results were as follows: First, the highest level of teachers' image was obtained for student teachers enrolled in a 2-year college, completed practicum in large cities and finished practicum at an institution with a size of 3-6 classes. Also, the highest level of 'recognition for practicum' of student teachers was observed when they were instructed by a guidance teacher with a degree from a graduate school and with a first degree certification in public kindergarten. Second, the satisfaction for practicum of student teachers was mostly affected by' the atmosphere of the practice institutions', while personality affected the teachers' image.

This study aims to explore the positive impact of Korean drama watching satisfaction on purchase intention for Korean products by considering the mediating roles of social distance to Korea, national image of Korea, and Korean product image. This study identified that Korean drama reduced the social distance to Korea while increasing the positive image of Koreas and Korean products. However, the reduced social distance was not positively associated with Korean product image and Korean product purchase intention. This implies that Korean dramas directly affect Korean product purchase intension and indirectly affect Korean national image and product image. This study supplies guidance to international marketers who aims to enter the Myanmar market. To use the Korean wave as a Korean product marketing tool, marketing strategies need to cover Korean culture-relevant materials such as cultural background, cultural characteristics, exposed products, and so on.

This paper describes the mechanism, guidance, sensor system, and navigation algorithm of METRO, a free ranging mobile robot. METRO is designed for use in structured surroundings or factory environments rather than unstructured natural environments. An overview of the physical configuration of the mobile robot is presented as well as a description of its sensor system, an omnidirectional laser range finder. Except for the global path planning algorithm, a guidance and a navigation algorithm with a local path planning algorithm are used to navigate the mobile robot. In METRO the computer support is divided into a supervisor with image processing and local path planning and a slave with motor control. The free ranging mobile robot is self-controlled and all processing being performed on board.

In infants and small children, ultrasound (US) guidance provides ample anatomical information to perform neuraxial blocks. We can measure the distance from the skin to the epidural space in the US image and can refer to it during needle insertion. We may also visualize the needle or a catheter during real-time US-guided epidural catheterization. In cases where direct needle or catheter visualization is difficult, US allows predicting successful puncture and catheterization using surrogate markers, such as dura mater displacement, epidural space widening due to drug injection, or mass movement of the drug within the caudal space. Although many experienced anesthesiologists still prefer to use conventional techniques, prospective randomized controlled trials using US guidance are providing increasing evidence of its advantages. The use of US-guided regional block will gradually become widespread in infants and children.

Intelligent devices using ICT technology have been introduced in the field of construction machinery to improve productivity and stability. Among the intelligent devices, Machine Guidance is a device that provides real-time posture, location, and work range to drivers by installing various sensors, controllers, and satellite navigation systems on construction machines. Conversely, the efficiency of equipment that requires location information, such as machine guidance, will be greatly reduced in buildings, and tunnels in the GPS blind spots. Thus, the other high-precision positioning technologies are required in the GPS blind spot zone. In this study, we will develop a relative position measurement system that provides precise location information such as construction machinery and robots in a local area where the GPS reception is difficult. A relative position measurement system tracks a marker in the form of a sphere installed on a vehicle by using the image base tracking technology, and measures the distance and direction information to the marker to calculate a position.

The more deeply the researches make progress in ocean researches including the seabed resource investigation or the oceanic ecosystem investigation, the more important the role of UUV gets. In case of study on the deep sea, there are difficulties in telecommunications between AUV and ships, and in data communication and recharging. Therefore, docking is required. In AUV docking system, the AUV should identify the position of docking device and make contact with a certain point of docking device. MOERI (Maritime & Ocean Engineering Research Institute), KORDI has conducted the docking testing on AUV ISIMI in KORDI ocean engineering water tank. As AUV ISIMI approachs the docking device, there is some cases of showing an unstable attitude, because the lights which is on Image Frame are disappeared. So we propose the docking algorithm that is fixing the rudder and stem, if the lights on image frame are reaching the specific area in the Image Frame. Also we propose the new docking device, which has a variety of position and light number. In this paper, we intend to solve the some cases of showing an unstable attitude that were found in the testing, which, first, will be identified the validity via simulation.

탐색기 적용 전술유도무기의 탐색기는 전술유도무기 개발 간 제한된 직경과 무게로 설계된다. 이러한 경우, 하드웨어 특성에 의해 탐색기 시야각, 분해능, 추적 알고리즘 등의 탐색기 성능에 제한이 존재하게 되고, 이로 인해 최대 표적포착 가능거리가 정해지게 된다. 장사거리용 전술유도무기의 경우 최대 표적포착 가능거리 이전까지는 INS 순수항법 또는 GPS/INS 통합항법으로 항법 유도비행을 수행하는데, INS 순수항법은 비행시간이 증가함에 따라 항법성능이 급격하게 감소하고, GPS/INS 통합항법의 경우 재밍상황에서 항법성능이 급격하게 감소한다. 본 논문에서는 앞서 언급한 최대 표적포착 가능거리와 항법장치 성능등 다양한 변수를 고려하여 전술유도무기 체계 관점에서 탐색기 영상 내 표적존재확률에 대해 분석할 수 있는 시뮬레이션을 수행하였다.

The purpose of this study is to compare and analyze the relationship among image, customer satisfaction and loyalty of fashion Extension brands. It is expected that this study will provide guidance to fashion companies that are planning to expand their brand in setting up marketing strategies and service strategies. The results of the study are the following. First, women consumers in their 20s had an perception that second brands provided diverse and unique products at cheap prices. However, after purchasing the products, they recognized that the second companies' service level was not so satisfying. Second, consumers were satisfied with the brand awareness, reputation, image, design, color, and packing conditions of the second brands while being not satisfied with the pricing. Third, when the study examined brand loyalty of second brands, consumers have shown high loyalty to the four subsidiary brands. Fourth, the satisfaction level for the four second brands had a significant effect on the brand loyalty for each second brands.

A control algorithm fir the unmanned vehicles was developed using image information received through a CCD camera that acquires more powerful information over the wide range of wave-length comparing with other sensors and was applied to a speed-sprayer. The algorithm consisted of straight mode for passing along with middle of two tree-rows and turning mode for changing from a row to another row. In case of turning mode, two marks of colored papers were employed to indicate turning point and to decide turning direction for various orchard situations. The method of analysis and image would be differed according to camera's tilt-angle and position that is set on the speed-sprayer. Hence, it analyzed the point of difference by making camera's up and downward tilt-angle.
