Kano model has been widely used to identify and classify customer attributes of a product or a service. The first step of Kano model application is the derivation of customer attributes, and brainstorming has been used conventionally for the purpose. A typical advantage of brainstorming is to get many ideas in a relatively short period, but the practicability of the derived ideas are known to be not so good. The derivation of good and practical ideas is important for the successful use of Kano model. Wish list, bug list and forced connection method as well as brainstorming were applied to PMP(Portable Multimedia Player) in order to derive customer attributes. To compare the idea generation methods, the derived attributes are classified and compared using Kano model.

This paper suggest that the derivation of good and practical ideas is important for the successful use of Kano model. Wish List, Bug List and Forced Connection Method as well as Brainstorming were applied to PMP(Portable Multimedia Player) in order to derive customer attributes. Wish List and Bug List are variants of Brainstorming, which are contrary to each other. Forced Connection Method is designed to bring about bisociation which is a typical characteristic of creative thinking.

This paper proposes a real-time dynamic storage allocation algorithm QSHF(quick-segregated-half-fit) that provides various memory allocation policies. that manages a free block list per each word size for memory requests of small size good(segregated)-fit policy that manages a free list per proper range size for medium size requests and half-fit policy that manages a free list per proper range size for medium size requests and half-fit policy that manages a free list per each power of 2 size for large size requests. The proposed algorithm has the time complexit O(1) and makes us able to easily estimate the worst case execution time(WCET). This paper also suggests two algorithm that finds the proper free list for the requested memory size in predictable time and if the found list is empty then finds next available non-empty free list in fixed time. In order to confirm efficiency of the proposed algorithm we simulated the memory utilization of each memory allocation policy. The simulation result showed that each policy guarantees the constant WCET regardless of memory size but they have trade-off between memory utilization and list management overhead.

The purpose of this study is to investigate the necessity, selection, organization and management of Must Books List in middle schools. A great book can change a person's life and future. Especially, reading in the juvenile period is important because of their intellectual curiosity and sensitivity. The results of the study were as follows: 1. The necessity of Must Books can be considered in two perspectives : One is the cultivation of emotion and sense of value and the other is the development of information abilities. 2. The general criteria for the selection of Must Books are whether a book is su n.0, pportive of learning activities, of extracurricular activities, and of activities for school festivals. And whether a book is contributing to the building of good characters of students or not should be considered, too. 3. The special attention should be given to such matters as the organizational and distributional ratio among subjects of the Must Books, the degree of difficulties, the ratio of books for both male and female students, the ratio of foreign books to domestics, the possibilities of further reading and the bibliographical matters. 4. The points to be duly considered for the management of Must Books List are the educational considerations, clearness of objectives, the elimination of commercialism and authoritarianism in the book selection. The Must Books List should be managed autonomously, depending on the characteristics of each school and be updated annually. However, the most important thing is that the teacher should be a good reader himself. 5. It is better to include short stories than the long one in the Must Book List. Students should be guided to read explanatory text first and then to move to the original text. And they should be exposed to books in various subjects and not to be too dependent on the Must Books List. They should be able to develop the problem solving ability through the reading of the Must Books. 6. Finally, the Must Books selection committee should be composed of both teacher librarian and subject teachers. It is desirable that books for the cultivation of emotion, for the establishment of sense of value, and for the development of information ability should be selected by consulting the various reading lists compiled by the Ministry of Education, the Board of Local Education and other authorities concerned.

In Domestic, the beginning of CM system was at December 1996 by 'Construction Industry fundamental law'. Today the needs of CM is more and more during 10 years. Although the time of CM's induction and high-quality human resources are insufficiency, various studies and developments's level through theoritical base and academic level is good which are compared by developed countries's. But still now the effort of CM product measure part, especially public sector is not enough. Besides, the existing check-list is for project owner so it needs to make up for balanced view as organized 4way-view of owner, CMr, designer, constructor. On this study, produce the list of check-list and then weight of each list by view of owner, CMr, designer, constructor. The completec check-list will be useful for CM product measure objectively .

High-throughput technologies enable the simultaneous evaluation of thousands of genes that could discriminate different subclasses of complex diseases. Ranking genes according to differential expression is an important screening step for follow-up analysis. Many statistical measures have been proposed for this purpose. A good ranked list should provide a stable rank (at least for top-ranked gene), and the top ranked genes should have a high power in differentiating different disease status. However, there is a lack of emphasis in the literature on ranking genes based on these two criteria simultaneously. To achieve the above two criteria simultaneously, we proposed to apply a previously reported metric, the modified area under the receiver operating characteristic cure, to gene ranking. The proposed ranking method is found to be promising in leading to a stable ranking list and good prediction performances of top ranked genes. The findings are illustrated through studies on both synthesized data and real microarray gene expression data. The proposed method is recommended for ranking genes or other biomarkers for high-dimensional omics studies.

This paper considers an economic design problem of a tree-based network which is a kind of computer network. This problem can be modeling to be an objective function to minimize installation costs, on the constraints of spanning tree and maximum traffic capacity of sub tree. This problem is known to be NP-hard. To efficiently solve the problem, a tabu list coupled genetic algorithm approach is proposed. Two illustrative examples are used to explain and test the proposed approach. Experimental results show evidence that the proposed approach performs more efficiently for finding a good solution or near optimal solution in comparison with a genetic algorithm approach.

There are a close relationship between natural disasters and train safety. So it is very important to guaranty train safety using reasonable rail-transport operation control against disasters. Therefore, based on the past record of rainfall at failure, rail-transport operation control for railway embankment under rainfall was set up. After slope check list at home and abroad had been analyzed, new slope check list was suggested and site investigations were carried out using this check list. In order to evaluate the stability of railway slopes under rainfall, explanatory variables and subordinate variables were selected for multi-variate analysis and critical rainfall was defined by statistical process. Rail-transport operation control including regional and geological properties was suggested by analyzing the critical rainfall and rail-transport operation control in other country, and this will be a good tool to control train speed under rainfall and to secure train safety.
