  • The purpose of this study was to understand the influence of instant noodle's selection attribution on satisfaction and to empirically analyze whether or not grade (elementary schoolchildren, middle school students, high school students) plays a moderating role in the relationship between selection attribution and satisfaction. Further, this study examined the differences in demographic characteristics among two groups of subjects divided by instant noodle's selection attribution. Based on a total of 1021 samples, this study verified a total of 3 hypotheses using the SPSS program. Data were analyzed by frequency analysis, chi-square, t-test, factor analysis, reliability analysis, cluster analysis, discriminant analysis, and hierarchical regression analysis. Results of the study were as follows. There were three different instant noodle's selection attributions among the children and adolescents investigated: internal element, external element, and company reliability. The multiple regression results show that internal element (=.391), external element (=.239), and company reliability (=.063) among customers' selection attributions had significant positive effects on satisfaction. In addition, the effect of selection attribution upon satisfaction was partially moderated according to grade. Further, cluster analysis divided subjects into two groups according to instant noodle's selection attribution: high-selection group vs. low-selection group. The wo groups of subjects classified by instant noodle's selection attribution were also different from each other in demographic characteristics. Limitations and future research directions are also discussed.

  • Advances in detection techniques, such as mutation and obfuscation, are being advanced with the development of malware technology. In the malware detection technology, unknown malware detection technology is important, and a method for Malware Authorship Attribution that detects an unknown malicious code by identifying the author through distributed malware is being studied. In this paper, we try to extract the compiler information affecting the binary-based author identification method and to investigate the sensitivity of feature selection, probability and non-probability models, and optimization to classification efficiency between studies. In the experiment, the feature selection method through information gain and the support vector machine, which is a non-probability model, showed high efficiency. Among the optimization studies, high classification accuracy was obtained through feature selection and model optimization through the proposed framework, and resulted in 48% feature reduction and 53 faster execution speed. Through this study, we can confirm the sensitivity of feature selection, model, and optimization methods to classification efficiency.

  • Malware Authorship Attribution is a research field for identifying malware by comparing the author characteristics of unknown malware with the characteristics of known malware authors. The authorship attribution method using binaries has the advantage that it is easy to collect and analyze targeted malicious codes, but the scope of using features is limited compared to the method using source code. This limitation has the disadvantage that accuracy decreases for a large number of authors. This study proposes a method of 'Defining semantic features from binaries' and 'Defining allowable ranges for redundant features using the concept of survival network' to complement the limitations in the identification of binary authors. The proposed method defines Opcode-based graph features from binary information, and defines the allowable range for selecting unique features for each author using the concept of a survival network. Through this, it was possible to define the feature definition and feature selection method for each author as a single technology, and through the experiment, it was confirmed that it was possible to derive the same level of accuracy as the source code-based analysis with an improvement of 5.0% accuracy compared to the previous study.

  • A design representation is reflected in the typicality of branch representation as a syntagm in combination with design factors. And the design factors form up paradigm as an attributive category which is reflected object and value of branch representations, and they are consisted of selection and combination in representative process. Selection and combination of the design attributive category also reflect the representation consciousness of operating in representative process, and they imply a cognizance about object and value of the representation. Therefore, branch representation appears an attributive structure which is required of a given field by means of the representative object and value. This is made up of the divided differentiation according to a combined mode. This study is to investigate the fact verification between typicality of attributive structure and each divided differentiation to measure consideration degree of attributive category which is consisted in the design representation. The attributive structure of representation which is affected the industrial design, the visual communication design, and the environmental design fields identifies to take the typical differentiation by means of evaluations and results of this study.

  • The purpose of this study is to analyze the factor giving effect to department selection, learning adaptation and attributional-style after entering school by selecting university students as targets and help high school students who will graduate soon and university students select department and direction. Those were analyzed by using 287 questionnaire data from June 1 to June 30, 2011. The study result revealed that 64.5% of students considered 'popularity and employment prospect' first when they select department. Generally, it was researched that when selecting department, 68.8% of women and 78.7% of health major considered 'popularity and employment prospect'(P<0.05, P<0.01). For learning adaptation and attribution trend of each major, health major showed that learning adaptation was high when motif was high and application score was high and for the relationship with attributional-style, health major showed higher internal attributional-style, showing significant difference(P<0.05). When synthesizing the results above, it is necessary to develop and use the program that can develop internal attribution trend of students on the basis of attributional-style. For planned and careful selection, it is necessary to perform synthetic consulting through direction search program that considers entrance period of middle school or high school, general affairs of university or direction guide to increase department or direction adaptation in the future.
