The concept of Total Quality Management may be perceived from different philosophical perspectives. In this paper we shall present a view on TQM from the perspective of Field-Being philosophy and compare it with the alternative philosophical views. From the perspective of Field-Being philosophy, the goal of TQM is to achieve the free flow of excellence at all levels: individual, team and organizational. By overcoming rigidity in thinking, behavior and performance TQM turns into an art-the Art of Quality Management, which is the source of true stakeholder delight.

Realistic real-time rain streaks rendering has been treated as a very difficult problem because of various natural phenomena. Also, in creating and managing a large number of particles, a large amount of computer resources had to be used. Therefore, in this paper, we propose a more efficient real-time rain streaks rendering algorithm by generating view-dependent rain particles and expressing a large amount of rain even with a small number. By creating a 'rain space' dependent on the field of view of the camera moving in real time, particles are rendered only in that space. Accordingly, even if a small number of particles are rendered, since the rendering is performed in a limited space, an effect of rendering a very large amount of particles can be obtained. This enables very efficient real-time rendering of rain streaks.

This research studied occupational view and perceptions of career education for elementary school by elementary school teachers and parents. Questionnaires were administered to 113 teachers and 523 parents. Data were analyzed by ${\chi}^2$ and t-test. Results showed statistically significant differences in teachers' occupational view by sex, educational background, field experience in elementary school, and experience of inservice teacher education; statistically significant differences in parents' occupational view by sex and age; statistically significant differences between teachers and parents in occupational views; and statistically significant differences between teachers and parents in perceptions of career education. Occupations providing stable livelihood were preferred by parents, by male teachers, teachers with masters' degrees, and by teachers whose education had included inservice training.

LabVIEW is faster than text language based program regarding development time and can monitor the output of data fast without the separate compiling work as the graphic-based graphical programming language. And, its coding is fast because it is designed by connecting the function with the wire and its has the merit of relatively intuitive UI. In this paper, data transmission and receiving between the program that is implemented in C language as CAN communication method that is strong against noise and used in power electronics application field variously and LabVIEW based program are explained. And, the design of LabVIEW based CAN communication program, data analysis and GUI screen composition that is convenient for monitoring are shown.

The purpose of this study was to develop a visibility evaluation system for cabin type combine. Human's field of view was classified into five levels (perceptive, effective, stable gaze, induced, and auxiliary) depending on rotation of human's head and eye. Divider, reaper lever, gearshift, dashboard, and conveying part were considered as major viewpoints of combine. Visibilities of combine was evaluated quantitatively using the viewpoints and the human's field of view levels. The visibility evaluation system for cabin type combine was consisted of a laser pointer, stepping motors to control the direction of view, gyro sensors to measure horizontal and vertical angle, and I/O interface to acquire the signals. Tests were conducted with different postures ('sitting straight', 'sitting with $15^{\circ}$ tilt', 'standing straight', and 'standing with $15^{\circ}$ tilt'). The LSD (least significant difference) multiple comparison tests showed that the visibilities of viewpoints were different significantly as the operator's postures were changed. The results showed that the posture at standing with $15^{\circ}$ tilt provided the best visibility for operators. The divider of the combine was invisible due to blocking with the cabin frame at many postures. The reaper lever showed good visibilities at the postures of sitting or standing with $15^{\circ}$ tilt. The gearshift, the dashboard, and the conveying part had reasonable visibilities at the posture of sitting with $15^{\circ}$ tilt. However, most viewpoints of the combine were out of the stable gaze field of view level. Modifications of the combine design will be required to enhance the visibility during harvesting operation for farmers' safety and convenience.

This paper deals with the parametric analysis of electric and magnetic fields generated by lightning discharges. The measuring system consisted of the plate-type electric field and loop-type magnetic field sensor, the voltage follower, the active integrator and LabVIEW software. The parameters of the electric and magnetic field waveforms produced by intracloud lightning strokes were presented.

The paper describes the effects of magnetic field on the electrochemical polishing process in the view of ionic in the electrolyte. Theoretical background was suggested how magnetic field increases the material removal efficiency and surface finishing ability Magnetic field changes the jonic movement in the electrolyte from linear motion to curved or complex oscillating one, thus increases the electrolytic current density and, as the results, the finishing efficiency.

연구목적: 일반적으로 교통사고는 산발적으로 발생하기 때문에 예방 및 방지대책 마련을 위한 현장조사 시 시간적·비용적으로 다양한 한계가 있다. 특히, 코로나 사태 이후 비대면 사회로의 전환으로 현장조사를 대체할 방안 마련이 더욱 필요한 실정이며, 이에 본 연구에서는 부산광역시 사상구를 대상으로 다양한 웹사이트에서 제공하고 있는 로드뷰에 대한 현장조사 대체 활용 가능성을 평가하였다. 연구방법: 연구방법은 '16~'22년간 발생한 교통사고 취약지점을 추출하여 교통안전법 ｢교통안전진단지침｣에서 제공하고 있는 현장조사 평가항목을 기반하여 로드뷰를 분석하였다. 연구결과: 주요 결과 사상구는 사상로, 대동로, 학장로 지점에서 고령 보행자 사고가 가장 취약하였다. 로드뷰를 통해 취약지점을 상세분석한 결과 사상로는 영업용 차량의 통제, 시장 상권에 대한 교통약자 보호 등이 필요하였다. 대동로는 불법 노상 주정차, 경사로 합류 구간 등이 취약하였고, 학장로는 과속이 쉬운 도로 등이 취약하였다. 이러한 분석 결과를 토대로 로드뷰의 현장조사 대체 가능성을 평가하였을 때, 로드뷰는 보·차도 분리성, 안전 시설물의 위치 및 간격 등 대부분 항목을 효과적으로 평가할 수 있었다. 하지만, 실측 수행 등 항목에서는 한계가 있었다. 결론: 즉, 로드뷰는 대부분의 현장조사를 대체할 수 있고, 실측 평가항목은 보조자료로 활용성을 높여 시간적·비용적 절감효과와 동시에 높은 효율성을 나타내는 것으로 판단할 수 있다.

최근 3차원 입체 디스플레이에 대한 관심이 증가하고 있다. 무안경식 다시점 입체 디스플레이(Multiple-view Autostereoscopic Display)는 관찰자가 셔터 글래스(Shutter glasses)또는 HMD(Head Mounted Display)와 같은 특별한 장치를 착용하지 않고도 여러 시점(Multiple-view)에서 입체 영상을 볼 수 있어 가상현실(Virtual Reality), 모바일, 3D TV 등의 분야에서 각광 받고 있다. 하지만, 디스플레이 설계 시 정해진 거리와 시역 내에 관찰자가 위치해 있어야만 입체 영상을 볼 수 있다는 문제점이 있다. 본 연구에서는 무안경식 다시점 입체 디스플레이 시스템을 구축하여 이 시스템에서 관찰자의 시점 변경에도 실시간으로 자연스러운 3차원 입체 영상을 보여 주기 위한 효율적인 GPU기반 렌더링 기법을 제안한다.
