This paper presents a quantitative measure of the degree of part commonality and redundancy in a product line based on entropy measure of information theory. The several possible methods of analysis are discussed and the use of the entropy measure is discussed. These commonality and redundancy measure can be applied to analyze the usage pattern of part across a product line and to determine which parts have the broadest usage across the firm's product lines. An analysis of the results by entropy statistics is compared with the practical part usage in a simulation of several types of part usage's distributions.

Initial reliability prediction done by calculation would be more practical if support by evidence from customer usage profile and field failure data to improve the prediction. Thus, the consistency of the design and the product would be practically validated. In this paper, it will address rationale and method to decide on Acceleration Factor (AF) to be used in Accelerated Life Test (ALT) through usage profile and field failure. The case study of tractor transmission is used to demonstrate the method which data obtained from surveys done on farmers, field visits and field failure data from service center. By considering all the elements, it will determine more relevant AF which indicates the real use conditions of the component.

In order to improve feed values of Korean agricultural by-products, various treatments including physical, chemical, physicochemical and fermentation were suggested in th is review article. Physical treatments such as chopping, grinding and pelleting reduce partiole size of agricultural by-products, and increase passage rate from the rumen, thus may increase voluntary feed intake and weight gain. Digestibility and voluntary feed intake of straw, rice hull and sawdust, also, may be increased by chemical treatment using sodium hydroxide or ammonia. Especially, because nitrogen content of by-products increase and toxic problem is not posed by ammonia treatment, it's practical usage is recommended in Korea. Silage or fermentation treatment using principles of microbial fermentation may improve palatability of low quality by-products. As mentioned above, it is concluded that various treatments suggested are desirable and improve feed value but may raise several problems. Unfortunately, because cost for installation and products is great and processing work is complicate, farmers are not using well these processing methods until now. Therefore, in order to increase the practical usage at farm level, it is thought that many research works be achieved for efficient process which have simple operation and low installation cost.

This study was intended to develop more reliable fruit sorting algorithm regardless of the feeding positions of fruits by using the neural network in which various information could be included as input data. Specific objectives of this study were to select proper input units in the neural network by investigating the features of input image, to analyze the sorting accuracy of the algorithm depending on the feeding positions of Fuji apple and to evaluate the performance of the algorithm for practical usage. the average value in color grading accuracy was 90%. Based on the computing time required for color grading, the maximum sorting capacity was estimated to approximately 10, 800 apples per hours. Finally, it is concluded that the neuro-net based color sorting algorithm developed in this study has feasibility for practical usage.

본 연구의 목적은 국내 대학도서관에서의 전자저널 이용 통계 제공 및 활용 현황을 조사하는 데 있다. 이를 위하여 서울 및 경기 소재 63개 대학교 및 대학도서관을 대상으로 온라인 설문지조사를 시행하였고 이 중 48개 도서관으로부터 응답지를 회수하여 그 결과를 분석하였다. 분석 결과 현재 제공되고 있는 이용 통계 데이터에 대한 만족도는 낮게 나타났으며 특히 비교 가능한 데이터의 부재 문제와 구독 대학도서관 전체의 평균 이용률에 대한 정보가 제공되지 않는 데 따른 불만이 높은 것으로 나타났다. 더불어 선행연구 조사 및 현행 이용 데이터에 대한 분석을 통해 전자저널 평가에 활용할 수 있는 이용 데이터 통계치로서 5가지 유형을 고찰하였다.

Many closed schools of about more 3,000(2006 year) have occurred all over the country according to governmental policy of 1982. These closed schools were sold or rent to institution, local government, and a private, and are used by various usage such as novitiate, institution, educational facility, art creation facilities, warehouse, and factory. But, unimproved closed school facilities are still reaching for about 450. Among practical use example of such closed school, alternative educational facility, practice facilities, art creation facilities etc. with closed schools which have general surrounding natural landscape and environment uses well preserved were applied consciousness and the practice about environmental problem to ecological concept. Also, a lot of discussions about ecological concept and study for desirable solutions about practical use of closed schools example have been achieved. However, it is hard to find various ecological practical use examples at filed. In such background, this research wishes to investigate changing space and facilities variously and its usage which is applied ecological concept with regional closed schools.

It is quite burden-some for non-native speakers of English to write and read more and more IT-related reports due to the rapid development of IT technology. Thus, this study aims at designing ESP materials by using huge volume of electronic ITU texts, corpora and concordancer SW. Various tests are designed to study the usage of articles, hyponym, agreement, synonym, and others. The results of this study will bring general and practical benefits to technical English writing and improving IT area students' lexical knowledge of actual English usage. The ESP materials produced by this study will also make an extensive contribution to other industries and academic areas in Korean society.
