The purpose of this study was to investigate the basic materials for enhancing the professionalism of 51 infant/toddler teachers through in-depth interview about the actual condition of child care centers. The results were as follows: First, the infant/toddler teachers got less credits of young child care and education subjects than day care teachers did. The current criteria for qualification of infant/toddler teachers was not appropriate for providing the child care services. An efficient and substantial curriculum must be designed to facilitate the day care services for infant/toddler teachers. Second, the infant/toddler teachers recognized that their roles were similar to child care teachers. The curriculum and practice must encourage and nurture the characters, beliefs, and dispositions of infant/toddler teachers. Third, it is necessary to review the various problems to enhance the professionalism of infant/toddler teachers. Several suggestions for enhancing the professionalism are discussed.

The purpose of this study is analyzing the frequent defect about each inspection part of Pre-qualification of residential building reconstruction and finding the cause of occurrence so that can supply a solution of the problem during the plalnning and constructure. The frequent defects are naturally following the deterioration and more occur in the structure body than a skin. The meaning that supply the cause and the managing method for preventing frequent defects about each inspection part is as follows. To prevent the defects, it is needed that the choice of the appropriate materials, giving a sufficient space for facilities, reliable constructure for the part of expecting the defects. The quality of life will go up due to making a good dwelling environment and extending the life cycle of structures from the inspection and managing the part of expecting defects.

A brake pedal for the flight control system of the Korean primary trainer is developed using composite material. The development includes the structural design, stress analysis, manufacturing and the qualification tests. A FEM analysis is used for the structural design and stress analysis. Autoclaving process is used to fabricate the composite brake pedal. For the qualification tests, modular fixtures are developed and applied. It is shown that the composite brake pedal developed meets all the structural integrity requirements specified in the military specification for aircraft parts.

Qualification test range for Lox/Kerosene gas generator cyle liquid rocket engine was determined by considering engine dispersion and flight inlet conditions. With various pump characteristics, the operation range of components and system was investigated through dispersion analysis. The variation of engine performance shows opposite trends in calibration and dispersion.

The objective of this study is to develop qualification analysis preliminary frame for railway personal injury accident. In this research, we develop accident scenarios to analyze systematically and evaluate quantitatively fatality accident scenarios for railway personal. The accident scenario analysis first identifies the hazardous events and explains the hazardous conditions that surround the accident and cause railway accidents. This method includes a feasibility test, a clustering process and a pattering process for a clearer understanding of the accident situation. Since this method enables an accident scenario analysis to be performed systematically as well as objectively, this method is useful in building better accident prevention strategies. Therefore, this study could serve to reduce railway accidents and could be an effective tool for a hazard analysis.

With industrial competitions more severe, most enterprises in Korea are placed in critical point to meet the changes. The tradition seniority systems of this country stand in the way to be more competitive in personnel sector especially . The purposes of this paper are to search the effective ways and methods in introducing and operating Job-performing Qualification System(JQS), one of the personnel systems based on human capability. To meet these purposes, various subjects - how to classify job groups, proper job grades number, how to define job grade, up-grading criterions, how to design the relations between personal rating system and JQS, and between compensating system and it - are reviewed and commented.

This report analyzes the Source Qualification Test which is composed of main functional and environmental tests for the localizing avionics(electronic subsystem for aircrafts and spacecraft) and high performance mechanical subsystem. Especially the detail test approaches of integrated servo actuators which is the main part to supply the power to the main and other flying control panel. Nowadays this subsystem works with mechanical and electrical engineering technique. In detail, electrical signal is used as input and transferring tool and mechanical part is the output as a power and manufacture the physical dimensions and functions. Finally in this review, the new test procedure to prove the function by the new manufacturer is established.

The objective of this study is to demonstrate and commercialized for on-board fuel storage system for the hydrogen fuel cell vehicles. Type3 composite cylinder is consisting of the full wrapped composites on a seamless aluminum liner. Especially, the seamless aluminum liner has been commercialized with development of fabrication through this study. The key technologies, including design, analysis and the optimized filament winding process for 350bar composite cylinder, were established and verified with design qualification test in accordance with international standard. And the facilities for fabrication and design qualification test have been constructed.

An APU(Auxiliary Power Unit) for helicopters has been developed in Korea and tested at the AETF(altitude engine test facility) in KARI(Korea Aerospace Research Institute) for the purpose of the military qualification. A cell correlation test was performed before the official test, and the results are within the tolerance. The APU has the capability of supplying electric power as well as compressed air to the helicopters. It was tested at bleed extraction conditions, electric power extraction conditions, and maximum continuous concurrent power conditions within the entire helicopter flight envelop. Some special test equipments were implemented for the measurement of air flowrate, electric power and so on. The tests were successfully performed and their results satisfy the requirements of the helicopters.
