The purpose of this study was to analyze the science inquiry problem finding ability of gifted elementary students of science and general elementary students. For this purpose, this study analyzed the types of science inquiry problems in an ill-structured problem finding situation. Also, this study has compared science inquiry problem finding abilities of those two groups. From the results of this study, new ways of improving student' science inquiry problem finding ability and selection of gifted students of science were suggested. The results of this study can be summarized as follows. First, most of the inquiry problems generated by the scientifically gifted and the general students in an ill-structured problem situation could be categorized into seven types (measurement, method, cause, possibility, what, comparison, relationship) according to the inquiry objectives, and both group found more problems in scientific context than in everyday context. Regardless of the context of problem, scientifically gifted students found more problems and the type of problems generated by them were more various than those of general students. Second, there were differences in problem finding ability between scientifically gifted and general students. Scientifically gifted students found more problems and the quality of problems were higher than general students.

This study investigated gender differences in the factors affecting elementary school students' ability to identify scientific problems. Scientific problem finding tasks, involving written instruments including IQ tests, content knowledge, science process skills, divergent thinking skills, intrinsic/extrinsic motivation, personality traits, and home environment were administered to 96 elementary school students(male; 50 & female: 46). The data collected was analyzed by means of a t-test, Pearson's correlation, multiple regression analysis, and canonical correlation analysis. The finding indicated that there were significant gender differences in scientific problem finding performance. Female students were significantly higher in both total score and elaborate score of scientific problem finding than male students. Personality traits and intrinsic motivation positively and extrinsic motivation negatively predicted male students' abilities in scientific problem finding. Science process skills, personality traits and intrinsic motivation positively and extrinsic motivation negatively predicted female students' scientific problem finding and IQ positively predicted female students' elaborate score of scientific problem finding.

There are several methods, in the literature, for finding the fuzzy optimal solution of fully fuzzy transportation problems (transportation problems in which all the parameters are represented by fuzzy numbers). In this paper, the shortcomings of some existing methods are pointed out and to overcome these shortcomings, a new method (based on fuzzy linear programming formulation) is proposed to find the fuzzy optimal solution of unbalanced fuzzy transportation problems with a new representation of trapezoidal fuzzy numbers. The advantages of the proposed method over existing method are discussed. Also, it is shown that it is better to use the proposed representation of trapezoidal fuzzy numbers instead of existing representation of trapezoidal fuzzy numbers for finding the fuzzy optimal solution of fuzzy transportation problems. To illustrate the proposed method a fuzzy transportation problem (FTP) is solved by using the proposed method and the obtained results are discussed. The proposed method is easy to understand and to apply for finding the fuzzy optimal solution of fuzzy transportation problems occurring in real life situations.

The previous empirical research suggests that problem finding is more important than problem solving in the creative process. Problem finding is increasingly recognized in theories of creativity. In spite of the importance of problem finding, there is little research to explain problem finding in Korea. This article reviews the research about problem finding and examines the nature of problem finding, the type of problems, the relation of problem finding and problem solving, the relation of problem finding and creativity, and the serendipity. Finally, theoretical and educational implications are discussed.

In transportation network problems, it is often desirable to select multiple number of the shortect paths. On problems of finding these paths, algorithms have been developed to choose single shortest path, k-shortest paths and k-shortest paths via p-specified nodes in a network. These problems consider the time as the main factor. In wartime, we must consider availability as well as time to determine the shortest transportation path, since we must take into account enemy's threat. Therefore, this paper addresses the problem of finding the shortest transportation path considering both time and availability. To accomplish the objective of this study, values of k-shortest paths are computed using the algorithm for finding the k-shortest paths. Then availabilties of those paths are computed through simulation considering factors such as rates of suffering attack, damage and repair rates of the paths. An optimal path is selected using any one of the four decision rules that combine the value and availability of a path.

Purpose: The purpose of this study was to explore and describe the experiences of the family caregivers using a nursing home for their elderly family members. Method: Participants for this study were 1 man and 9 women caregivers. Data was collected through in-depth interviews from October, 2005 to April, 2006 and analyzed using Strauss and Corbin's grounded theory methodology. Results: "Finding a way to live together" emerged as a core category and it reflected expanding consciousness allowing them to see each other in a more positive view. The basic social process of "finding a way to live together" includes 3 phases: 1) recognizing the problems, 2) finding solutions to the problems, and 3) accepting the changes in their surrounding. Lack of privacy, family troubles, extreme distress, and unavailable caregivers are reflected in the process of recognizing the problems. The process of finding solutions was making a decision, obtaining family agreement, choosing the best nursing home, and enduring the financial burden. Possible outcomes of the last phase include recovering peace of mind and continuing conflict. Conclusion: Findings from this study offer suggestions for developing a strategy to help not only the elderly but also the family caregivers.
