Even though the field of the service industry in Korea occupys almost half of the whole industry, the development of this field lags behind greatly in comparison with other fields. Therefore, confronted with the problem of improving the productivity of the service industry as an immediate problem this study aims at grasping the present situation of productivity in relation to the service industry in korea and its international standard, and indentifying the cause of declined productivity. chapter 2 accounts for the controversial problem of measuring productivity and the method of measuring productivity. And Chapter 3 is concerned with the comparative analysis of the present situation of service productivity in Korea, and that of productivity in such advanced countries as U.S.A and Japan and of service productivity in such competitive counterpart as Taiwan and Singapore. As a result the productivity of the service industry in Korea showed poor results in comparison with competitive counterparts as well as advanced countries, especially Singapore. The cause of this poor productivity in the service industry, as a result of its analysis in chapter 4, is as follows : Firstly, for its reason attributed to the characteristics of the service industry the sector of the service industry could helping lagging behind in comparison with the sector of the manufacturing industry. Secondly, for its reason of underdeveloped process of industrialization development of the service industry in korea has still come to fullmaturity. Thirdly, owing to the lack of adjustment to service economization, the pattern of economy is lacking in adjusting itself to economization ever though the economization as regards the field of service is extremely rapidly being made. Fourthly, the awareness of the management on productivity of the service industry is deficient. Therefore, measures for the improvement of productivity of the service industry in korea are as follows : Firstly, korea economy requires to make an effort to adjust itself to service economization as urgently as possible. Secondly, operation of the large-scale whoresale center, the industrial products delivery complex, and point of sales system have to be actively promoted through distribution modernization of wholesale and retail businesses of organization and cooperation of medium or smaller merchants and the modernization of conventional markets. Thirdly, for the purpose of the improved productivity of the financial industry, government should proceed to upbring the sound development of the financial industry and autogenous force. Fourthly, as the improvement of productivity in the service industry should be achieved through quality control, managerial efforts are required as regards service quality.

LED 비디오월을 사용하는 방송환경에서HD 카메라의 적정 초점거리 연구

LED 비디오월을 방송 현장에서 사용하기 위해서는 몇 가지 알아두어야 할 사항이 있다. 첫째, 픽셀이 촘촘히 배열되어 있기 때문에 짧은 배열 주기로 인한 무아레 현상이 나타날 수 있고, 둘째, 픽셀 간의 거리(픽셀피치)가 촬영하는 카메라 이미지 센서에 기록될 수 있다. 무아레 현상이 발생하거나 픽셀피치가 관찰되게 되면 시청자의 입장에서는 불편함을 느끼게 된다. 무아레 현상은 카메라의 촬영거리나 각도를 조정하면서 감소시킬 수 있지만, 픽셀피치가 이미지 센서에 녹화되는 걸 방지하기 위해서는 LED 비디오월과 카메라와의 거리를 충분히 확보하거나, 거리가 확보된 상태에서도 픽셀피치가 녹화되지 않도록 방송 현장에서 사용되는 줌렌즈의 배율을 적절하게 변화시켜 운용해야 한다. 원하는 화각을 얻기 위해 배율을 변경시켜 초점거리를 변동시키게 되면 의도치 않게 픽셀피치가 녹화되는 결과를 초래할 수 있다. 본 논문에서는 비디오월과의 거리가 충분히 확보된 상태에서 줌렌즈의 배율을 변경하면서 픽셀피치가 관찰되지 않는 범위에 대해 알아보았다. LED 비디오월에 영상을 재생시켜 B4 마운트 줌렌즈를 장착한 HD 카메라와 서버를 사용해 LED 비디오월 상태를 녹화하였고, TV 화면으로 재생하여 픽셀피치가 관찰되는지 확인해 보았다.

Holographic Stereogram can provide the depth perception without the visual fatigue and dizziness because it use multiple images acquired from the multiple viewpoints. In order to produce a holographic stereogram, it is necessary to obtain perspective images of a live object and record it on film using a digital hologram printer. when acquiring perspective images, the hologram without distortion can be produced only when the perspective images with a constant distance between the camera and the target is obtained. If the target is small, it is possible to keep the constant distance from the camera to object. but if it is large, this is difficult to keep the constant distance. In this study, we photograph the large object using the POI (Point of Interest) function which is one of the smart flight modes of drone to produce perspective images required for the hologram production. after that, problems such as the unexpected shakings and distance change between camera and object is corrected in post production. as a result, we produce the perspective images.

A Study on the kinematic Analysis of Head Hitting Motion during KumDo Learning The study was undertaken to analysis kinematic variables of Head Hitting Motion during KumDo Learning. For this aim, the subjects participated in the experiment consist of 3 high school athlete in Cheju Do. The equipments for this study was composed of Cinematography (Panasonic Video Camera 2ea) and control point object to translate the coordination in space. The digitizating point of body consisted of 22 points and used Body segment parameter with Kwon 3D Motion Analysis System. The conclusions resulted from the analysis as following. 1) Total elapsed time from start to impact was 0.496 sec. reaction time was mean 0.110 sec. in Temproal variables 2) COG mean horizontal displacement showed -0.733cm in reaction phase, 16.988cm in top phase, 0.496sec. in impact phase. 3) It showed a tendency lowing COG position and mean vertical displacement showed 0.211cm in reaction phase, -0.949cm in top phase, 16.988cm in impact phase. 4) The highest Mean horizontal velocity showed 112.372 m/s in impact phase, and mean vertical velocity 2.323m/s in starting phase, -1.477m/s in top phase, 24.716 m/s in impact phase. 5) In angular variables, It showed significient extension of upper arm and rapid flexion in impact phase in all subjects. 6) It showed rapid increasing tendency in Gum segment in impact phase angular velocity in all subject and showed a little difference vertical & horizontal displacement and velocity in linear variables. 7) It showed highest increasing pattern in Gum segment in velocity, rapid flexion in impact phase, extension in top phase during Gum swing motion.

The purpose of this study was to measure the quality of life in family having children with disabilities and to find out ways supporting for them. We surveyed questionnaires about stress, sibling-relation, and family role. After that, we analyzed this data using frequency-analyzing. The results of this study were as follows: First, they worried about instructional intervention and social adaptation for their children. Especially we found that the drinking problem of their parents happened. Second, sibling-relations were usually good. But sometimes the violence problem happened. Third, the distinction between sibling and children with disabilities existed in the quality of life. Last, family felt uncomfortable, unhappy, and resentment. This study had such limitation as the small number of survey districts and appropriation in measure variables.
