  • The purpose of this study is to have a preliminary study in order to develop a test which can comprehensively measure anxiety of elementary schoolchildren in middle grade. Following things are conducted to meet this task; first, to look into compositions of the anxiety of elementary schoolchildren in middle grade, to prepare proper questions to measure it and to develop a test; second, to look into whether such questions are fully understood by schoolchildren; third, to look into whether reliability and adequacy thereof are proper or not. Conclusion of the study is as follows; anxiety test of elementary schoolchildren in middle grade showed all the things related to general anxiety, social anxiety, study anxiety, examination anxiety, announcement anxiety. However, there were differences as per subordinate factor and detailed area. And reliability and adequacy of anxiety test for elementary schoolchildren in middle grade were appropriate. and such data could be valuably used for preparing anxiety test. To summarize the study result above, the test developed in this study supplements weak point of existing test instrument and reveals anxiety experienced by elementary schoolchildren in middle grade, and harmoniously composes all the kinds. It is meaningful that the test lowered applicable object to schoolchildren in middle grade who are in anxiety formation stage and also feel anxiety most strongly. In addition, it may be used usefully for living guidance and consultation to efficiently cope with anxiety by measuring base line regarding anxiety of individual schoolchildren in middle grade.

  • Given the specific mean shift outlier model, the standard approaches to obtaining test statistics for outliers are discussed. Accuracy of outlier tests is investigated using subset curvatures. These subset curvatures appear to be reliable indicators of the adequacy of the linearization based test. Also, we consider obtaining graphical summaries of uncertainty in estimating parameters through confidence curves. The results are applied to the problem of assessing the accuracy of outlier tests.

  • This paper analyzed the effect of job search channels on the occupational adaptation of college graduates, with the Graduates Occupational Mobility Survey(GOMS) data. The analysis results are as follows: First, when using human networks for getting jobs, not only the educational level and major adequacy, but also the workplace satisfaction and the job satisfaction were higher than when using non-human networks. Second, as in the mediating effect of the relationship between job search channels and occupational adaptation by Sobel-test, it was found that there was a partial mediating effect of educational level and major adequacy, excluding skill level adequacy. The results of this study shows that human networks, by serving as an effective information transmitter on person-job fit between job search and recruitment, contribute significantly to improve occupational adaptation of college graduates. These results imply that strategic utilization of human networks in job search activities is important, and that it is necessary that career-related programs in the universities or the employment service institutions systematically include the importance and methods of using human networks.

  • This study was conducted to develop and validate the Sugar Intake Reduction Test (SIRT) for young children, and included eating behaviors, attitude, and nutritional knowledge about sugars. A draft version of the SIRT was developed after literature review. The final draft of the SIRT was established after two pilot tests of 5 year old children and an expert group's review, and is comprised of a one on one test between an investigator and a child using picture tools. It contained of 20 questions which included 3 components: eating behaviors (5 items), preference for sugar sweetened food (10 items), and nutritional knowledge about sugars (5 items). The final SIRT was conducted on 181 children 5 (n=100) to 6 (n=81) years old, to examine its item and test adequacies. The passing rate of most items significantly increased with increasing age, and most of the item discrimination also differed significantly between the below and upper score groups. The content validity was given a high score by professionals (mean score 3.9 out of 4). Reliability of all the items in the SIRT was high (Cronbach's ${\alpha}=0.82$). Moreover, the total component and the sub-component scores of the SIRT correlated significantly. Our results indicate that the SIRT is a valid tool to measure sugar intake reduction in young children aged 5~6 years.

  • The purpose of this study was to investigate the influence of perceived adequacy resource(PAR) and locus of control on the stress from the family resources management in housewives. The subjects of this study were 474 married women who lived in apartment in Taegu, . A questionaire was used as survey method. Factor analysis and MANOVA were employed for data analysis and Scheffe test for post-hoc analysis, . The main findings were ; First the effect of PAR on the degree of the stress from the family resources management was not different according to locus of control. Second the stress from the family resource management was found to be significantly different according to PAR.

  • The purpose of the study was to explore effective satisfaction factors for continuous partnerships between fashion companies and artists. A questionnaire was developed by the researchers and results were collected from a total of 273 people who were working for a fashion company or working as an artist. Data was analyzed by the use of a frequency test, a reliability test, an exploratory factor analysis and a structure equation model analysis using AMOS 18.0. The results of the study were as follow. First, profitability and adequacy had significant effects, but awareness had no effect on confidence concerning the partnership. Second, awareness and profitability showed significant effects, but adequacy showed no effect on the flow among those in the partnership. Third, confidence had a significant effect on flow. Fourth, among the partnership factors, confidence and flow had significant effects on partnership satisfaction. Fifth, flow showed a significant effect on the intent for a continuous partnership, but confidence showed no effect.

  • The effect of noise on the input motion for the seismic test of structures using shaking table was studied. Table motions usually contain high frequency contents which influence the PGA of input motions. It was shown that the noise influenced PGA much with minor changes in high frequency contents. The Butterworth bandpass filter can be effectively used. The adequacy of the table motion should be judged based on both the frequency contents and the PGA.

  • Testing approaches for configurable software product lines differs significantly from a single software testing, as it requires consideration of common parts used by all member products of a product line and variable parts shared by some or a single product. Test coverage is a measure of the adequacy of testing performed. Test coverage measurements are important to evaluate the adequacy of testing at the software product line level, as there can be hundreds of member products produced from configurable software product lines. This paper proposes a method for measuring code coverage at the product line level in configurable software product lines. The proposed method tests the member products of a product line after hierarchizing member products based on the inclusion relationship of the selected features, and quantifies SPL(Software Product Line) test coverage by synthesizing the test coverage of each product. As a result of applying the proposed method to 11 configurable software product line cases, we confirmed that the proposed method could quantitatively visualize how thoroughly the SPL testing was performed to help verify the adequacy of the SPL testing. In addition, we could check whether the newly performed testing for a member product covers the newly added code parts of a feature.
