Automatic inspection system software for display image characteristic of CRT is developed. There are two major contributions of this software development. One is that the data from measuring equipments which was usually collected manually is automatically collected through RS-232C port and is saved in computer, then, trend analysis graph and final reports are generated. The other is that evauation of characteristic of electron gun was automatically processed by CCD camera and image processing technique. The system is developed under MS-Windows environment utilizing Borland C++4.0 Compiler and DT 3852-8 image processor board. This system can save the time and man power to measure and to anayze the image characteristics relative to current method.

이 논문은 노인교육에 대한 정부의 정책지원이 이루어진 시점부터 현재까지, 그 전개과정과 특징을 확인하는 것을 목적으로 한다. 이는 기존 노인교육정책 관련 연구들이 현재의 정책현황에 대한 상황기술과 이를 바탕으로 한 향후제언 성격의 담론 논의에 중심을 둠에 따라, 현재의 모습으로 발현되기까지의 정책과정에 대한 분석이 소홀히 다루어진 것에 대한 문제의식에서 출발한다. 연구자는 '한국노인교육정책은 어떻게 진행되었는가'라는 질문을 제기하며, 관련 문서에 기초하여 정책의 전개 과정과 특징을 찾는데 주목하였다. 분석을 통해 노인교육에 대한 정책지원은 1970년대 후반 새마을운동의 대중화를 위한 국민교육의 일환으로 시작·강화되었고, 현재에는 노인 인적자원양성을 위한 정책 지원으로 이어지고 있음을 확인할 수 있었다. 이 과정에서 시기에 따라 정부의 정책지원은 그 목표와 대상, 그리고 지원체계가 변화되는 특징을 보인다. 또한 1990년대 후반 다각적으로 수립된 노인교육정책들은 대부분 집행으로 이어지지 못하고, 정책 수립과 집행 사이의 상당한 불일치를 보여주고 있음을 확인할 수 있었다.

The purpose of this study is to analyze the characteristic of street markets in land development district, Dae-gu(Sung-su, Yeoung-san and Si-gy Land development districts). The result of this study is as follows, Street markets are located between detached housing estates and cooperative housing estates. Street markets are classified as private road type, linear street type and mixed type, The influential area of street markets is extended form inside of detached housing estates to arterial road. The vitality of street markets is explained by the scale of dwelling area, road system and variety of function.

This study is about land use and site plan for resident redevelopment for districts with existing residents. The study suggests development direction focusing on preserving the regional characteristics, and presentation of suburban-style housing complex reflecting on the future tenant's individuality and demand. The preexisting development approach for suburban-style housing complex which was planned by the developer, failed to recognize taste of the future tenants. Profitability being the priority, it also resulted in a serious environmental disruption. In this development however, through a systematic direction for site development and site analysis, conducting surveys through future tenants, attempted for a continuous growth of the community. The study is presented covering the following areas; site's pathway system, nature conservation plan, lot plan, land use and arrangement plan, and community facility.

We know that curriculum is, first of all, related to teaching materials, namely, contents. Therefore, when we think of mathematics curriculum, we must take account of characteristic of mathematics. Vygotsky has studied the development of scientific concepts and everyday concepts. According to Vygotsky, scientific concepts grow down through spontaneous concepts; spontaneous concepts grow upward through scientific concepts. And mathematics is a representative of subjects dealing with scientific or theoretical concept. Therefore, his study provides scientific basis for mathematics curriculum design. In this context, Davydov notes that everyday concepts are developed through empirical abstraction, while scientific concepts require a theoretical abstraction. And Davydov constructed the curriculum materials for the teaching of number concept. Davydov's curriculum is an example of reflecting Vygotsky' theoretical view and his view about the types of abstraction. In particular, it represents mathematical characteristic of a 'science' by introducing number concept through quantitative relationship and use of signs. In conclusion, stance mathematical concepts have scientific characteristic, mathematics curriculum reflects this characteristic.

This thesis aims to report the result of an evaluation of the aerodynamic characteristic on the purchase conditional pantograph model that has developed for applying to the KTX-I. Development pantograph was derived the result of aerodynamic characteristic through a wind tunnel test. And design modification was proceeded to solve the difference of aerodynamic characteristic by pantograph's operating direction. The verification test and adjustment test about the modified pantograph's aerodynamic characteristic were progressed on the KTX-I. To be corresponded with requirements, the airfoil and spoiler were used.

Purpose - This research is to verify job fitness, empowerment, and recognition of career development support having the influence on formation of occupational identity in Korean food franchise distribution company. Research design, data, and methodology - Total 600 copies have been distributed and 394 copies have been collected, the covariance structure analysis has been implemented to verify the presented research hypothesis. Results - Demand fit and competency fit being the lower level of job fitness appeared not to have significant influence on occupational identity, and also these do not have the significant influence on the empowerment. Even though formal career development support being lower level of career development recognition appeared to have significant influence on empowerment, nonformal career development support appeared not to have significant influence on empowerment. Formal career development support and nonformal career development support appeared to have significant influence on occupational identity. Finally, empowerment appeared to have significant influence on occupational identity. Conclusions - It is implied that the psychological and subjective success felt in employee's career course may be improved by the job related job fitness, the initiative being individual characteristic and formal and formless career development support being organizational characteristic.

The effects of swirl on early flame development and late combustion characteristic were investigated using a high speed single-shot visualized 51 engine. LDV measurements were performed to get better understanding of the flow field in this combustion chamber. Spark plugs were located at half radius (R/2) and central location of bore. High speed schlieren photographs at 20,000 frames/sec were taken to visualize the detailed formation and development of the flame kernel with cylinder pressure measurements. This study showed that high swirl gave favorable effects on combustion-related performances in terms of the maximum cylinder pressure and flame growth rate regardless of spark position. However, at R/2 ignition the low swirl shown desirable effects at low engine speed gave worse performances as engine speed increased than without swirl. There were distinct signs of slow-down in flame growth during the period when the flame front expanded from 2.5mm in radius until it reached 5.0mm apparently due to the presence of ground electrode. There seemed to be heat transfer effect on the flame expansion speed which was evidenced in high swirl case by the slowdown of the late flame front presumably caused by relatively large heat loss from burned gas to wall compared with low- or no-swirl cases.

During helicopter rotor system development process, whirl tower test is conducted basically. For conducting whirl tower test during bearingless hub development process, design new blade or using existing blade with repair or remodeling. Because simple shape and efficient aerodynamic characteristic, BO-105 blade is used for hub system development widely. Originally BO-105 blade is used for hingeless hub, ho flap stiffness and lag stiffness on blade root area is relatively low. So applying BO-105 blade to bearingless hub whirl tower test, root area have to be reinforce. In this process, blade root area's section property will be changed. In this paper, suggest reinforcement method of BO-105 blade root area and study dynamic characteristic of bearingless rotor system with reinforcement BO-105 blade.
