최근 학교 현장에 인터넷의 보급과 함께 새로운 방식의 교육 형태와 학교 업무 전산화의 필요성이 대두되었다. 이에 따라 새로운 교육 방식으로서 ICT (Information & Communication Technology) 활용교육을 통한 다양한 교수-학습 모형이 시도되고 있으나, 학교 업무 전산화는 오프라인에서 종이문서를 단편적으로 입력하고 데이터를 출력하는 형태에 머물러 있다. 따라서 본 연구에서는 웹 기반의 업무처리 방식에 따른 초등학교 과학 교구 관리시스템을 제안한다. 본 시스템의 특징은 다음과 같다. 첫째, 학교에서 관리하는 과학 교구 관리업무를 시 도교육청 기준안에 따라 표준화, 정보화하고 또한 교육청의 교구기준에 따라 자료를 선정하여 업무의 효율성과 신속성을 증진시킨다. 둘째, 교구관리시스템을 기초 정보 관리, 교구 기준 관리, 교구 현황 관리 등으로 구성하여 필요한 정보를 쉽고 빠르게 파악할 수 있다. 셋째, 초등학교 교구기준에 맞추어 설계함으로써 기준량, 보유량 및 부족량의 파악과 교구확충계획을 효율적으로 수립하여 업무의 경감과 인력 및 시간의 낭비를 줄일 수 있다.

Measurement is a essential part in all kinds of industry, especially in manufacturing. But until now, measurement hasn't been located to the core of manufacturing in domestic. This study suggests improvement guide line for the multilateral problems of measuring instrument operation based on the investigation of small and medium-sized enterprises. To use measuring instrument correctly, man who treat it must be accustomed with the structure, the performance, the method. The measuring instrument must be corrected periodically. The correcting-schedule is established with environments with considering accuracy, stability, purpose, condition, and frequency.

Measurement is used for evaluation of product or process exactly. If it couldn't measured correctly, Quality-cost must be raised and it would be hard to improve product quality. So, this study suggests improvement guide line for the multilateral problems of measuring instrument operation based on the investigation of 157 small and medium-sized enterprises in February, 2008. To use inspection gig correctly, man who treat it must be accustomed with the structure, the performance, the method. The inspection gig is selected properly for the measurement goal. If not, results couldn't be correctly or wasted time, efforts, and costs. When selecting a inspection gig, the locating, the clamping, and the efficiency must be considered.

Achievement degree can be improved by display offering more effective process about cognitive, pattern recognition than making observers use memory, integration, and cognitive process of control. And this research is proved by several scholars' researches [4][5][7][9]. In this study, researches was conducted about cognition according to layout of object in instrument panel. To decide layout of instrument panel, Cognition value was preferentially decided about all location. And then, objects are arranged to correct position of low cognition following the inferior procedure about each location. As a result, we get conclusion that gauge location is taken in high importance order through mechanical importance degree bringing huge damage during driving forklift-truck.

This paper analytically studies how to choose hedging instrument for firms with steady operating cash flows from value maximization perspective. I derive a formula to determine option's optimal strike that makes hedged cash flow have the best monetary payoff given a hedger's view on the underlying asset. I find that not only the expected mean but also the expected standard deviation of the underlying asset in relation to the forward price and the implied volatility play a crucial role in making optimal hedging decision. Higher moments play a certain part in hedging decision but to a lesser degree.

The study was surveyed to evaluate the foodservice program. The survey was conducted based on instrument which was developed by reviewing previous research. The instrument was provided to 60 nutritionists at the elementary schools in Taegu area. The data include 4 major parts of task performance rate, delivery and service, menu management, and satisfaction of foodservice facilities. Data obtained from survey are analyzed by SPSS program. These results show that the performance rates of determination of nutritional needs and menu planning is high to 98.3％ both and 23％ of nutritionists don't perfomed nutrition education.

This paper presents a linear programming formulation of the aggregate production planning problem for an optical instrument manufacturing company. Taking into account of the various requirements of the company, an L.P model is developed whose objective is to minimize the total cost of production during the planning horizon. The application results and its implications are well understood by the management and expected to be used as a guide line for future production planning.

Purpose: The purpose of this study was to develop an instrument of task performance evaluation for clinical nurses, thus testing the validity and the reliability of the scale. Method: Data was collected from 84 Head Nurses and 255 General Nurses. A conceptual framework, composed of 4 factors of meaning in task performance evaluation, was identified through review of the relevant literature. A total of 78 items were developed and were used on a five-point likert scale. Through factor analysis, items whose factor loading was below 0.50 were deleted, thus 35 items remained. To test the validity and reliability of the instrument, the SPSS 11.0 windows program was used. Result: The results of the factor analysis indicated that 4 factors were classified and the cumulative percent of variance was 67.54%. The results of the reliability test indicated that Cronbach's coefficient of the total 35 items was over 0.9176. The results of the factor analysis indicated that factor loadings of all items was over 0.50. Conclusively, the validity and the reliability of the scale were proven. Conclusion: This study was identified as a tool with a high degree of reliability and validity.
