  • 최근 음악을 재생할 수 있는 다양한 소형기기들의 발전이 이루어지고 있다. 휴대용 음향기기에서 곡을 탐색할 경우, 곡 탐색 습관의 특성상 눈으로 확인하지 않고 손을 사용한 촉각적 피드백만을 이용하는 것이 대부분이다. 또한 곡 탐색 과제는 청각적인 표적을 찾는 것임에 반하여, 지금까지 청각적인 단서에 대한 연구의 대부분은 시각적인 표적을 찾는 것에 집중되어 있었다. 본 연구에서는 청각적인 표적을 탐색하는데 있어 청각적 위치 단서가 미치는 영향을 알아보고자 하였다. 주어진 곡 리스트를 암기한 후, 화면에 제시되는 표적 곡을 탐색하는데 있어 청각적인 위치 단서가 있는 좌우 조건, 가운데 조건, 그리고 무음 조건의 경우에 따른 곡 탐색의 정확률과 반응 시간을 측정하였다. 과제는 정상과 오류 두 가지 유형으로 구성되었다. 결과는 청각적인 위치 정보가 포함된 좌우 조건이 정상 과제와 오류 과제에 있어서 가운데 조건과 무음 조건에 비하여 모두 유의미하게 짧은 반응 시간을 보였다. 본 실험 결과는 휴대용 음향기기뿐만 아니라 위성항법장치(GPS), 가상환경(Virtual Environment) 등과 같이 청각적인 표적을 찾아야 하는 과제를 포함하는 환경에도 적용될 수 있을 것이다.

  • This study explored factors affecting consumer's external information search effort on online shopping malls through three approaches(cost-benefit approach, psychological motivation approach, and web-site theory approach) respectively, and designed the integrative model through searching the relationships among them. In this study search motivation are designed to be explained by search benefit and search cost that are explained by factors related to the web site and search efforts are designed to be explained by search benefit, search cost and search motivation. The results from our empirical research showed that search motivation, search benefits and prior knowledge on online shopping malls have a direct effect on consumer external information search effort. On the other hand, it was verified that the search motivation was affected by search benefits and purchase involvement, and the search benefits are directly influenced by purchase involvement, constructive simplicity, search convenience and trust. In addition, purchase involvement, time press, constructive simplicity and search convenience had direct effects on the search cost.

  • This study analyzed the effect of the cognitive style of field dependence/independence to the information-seeking behaviors of 250 undergraduate students. The cognitive style of field dependence/ independence was examined by Group Embedded Figure Test (GEFT), information-seeking behaviors were examined by information-seeking performances, and survey for information-seeking behaviors. As a result of the analysis, the cognitive style of field dependence/independence affected items of information-seeking performances except one item among items set in this study. The cognitive style, the cognitive characteristics acting in the process of cognitive activity affected the actual activities of information-seeking behaviors. The cognitive style of field dependence/independence affected the seeking process except the results of seeking and general information-seeking behaviors in the areas of information-seeking behaviors. Therefore, the study of cognitive style can be effective in the seeking process areas of information-seeking behaviors.

  • This study was performed with a view to examine the nature and difference of EFA(Exploratory Factor Analysis) and CFA(Confirmatory Factor Analysis), and to compare the analysis process and result of EFA and CFA with the same data. The result of empirical analysis was as follows. Meanwhile, p.1, p.3 was removed owing to hampering the convergent validity in EFA, p.3 was removed owing to hampering the discriminent validity in CFA. EFA was reduction process of muti measurement variables to a few factor, but CFA was understanding and confirmatory process of measurement and latent variables' relation. Eventually, this study showed that EFA and CFA used different methology, thus the different outcomes appeared although using the same data, and implicated resonable application of methology according to given data.

  • To sustain successful relations with its customers, an internet business enterprise has to understand precisely the difference between customers' behaviour and their purchasing behaviour pattern on its customer basis. For this purpose, I closely looked into what difference there was between a leading variable which had an effect on internet customer long-term orientation and a special variable depending on period of transactions To prove this research, I analyzed collected data in which customers had experienced in shopping at internet shopping mall and discussed strategic current issues about its analytic results.

  • This study is to figure out the activity and disposition of gifted students with face plot in exploratory data analysis at middle school mathematics class. This study has begun on the basis of the doing mathematics at multivariate analysis beyond one variable and two variables. Gifted students were developed the good learning habits theirselves. According to this result, Many gifted students have an interesting experience at data analysis with Face Plot. And they felt the useful methods of creative thinking about graphics with doing mathematics at mathematical tasks. I think that teachers need to learn the visualization methods and to make and to develop the STEAM education tasks connected real life. It should be effective enough to change their attitudes toward teaching and learning at exploratory data analysis.

  • This study analyzed the effect of metacognition to the information-seeking behaviors of 250 undergraduate students. For this, metacognition was examined by the inspection form that the Educational Psychology Programs of the Department of Education, at Seoul National University, developed in 2005. The information-seeking behaviors were examined by the observance of the established information-seeking performances and through a survey. As a result of the analysis, metacognition affected the items of the survey for the information-seeking behaviors, excluding one item. As metacognition is the cognitive characteristics acting after the cognitive process, it affected thinking activities that were conducted by the brain. In addition, metacognition affected the seeking process, the results of seeking, and the general information-seeking behaviors. Therefore, the study of metacognition is effective in the overall aspects of information-seeking behaviors including the seeking process, the results of seeking, and the general information-seeking behaviors.

  • In this paper we propose a new fast peak searching method using the gradient and present simulation results. The proposed method is a solution to the problem that finds the peak(maximum) of the unimodal function on a finite interval with minimum searching steps. Its main application is the auto-focus in the mobile phone. We propose the three steps to find the peak; periodic search, gradient-based search and detail search. In simulation we generated the Gaussian functions with white noise and have the result of about 8 searching steps and 1.04 errors on average.

  • A variety of searcher traits, characteristics, subject background and behaviors have been the subject of investigations exploring various hypotheses relating to searching performances. Previous studies have focused on searchers personal characteristics such as training, experience, subject knowledge, intelligence, cognitive style, attitude and searching style, Each of these factors is examined in this paper in order to find out searcher's personal characteristics affecting searching performance. Surprisingly, searching training and experience have not been found to influence searching performance. The hypothesis that intellectual ability correlates with the ability to online search seems to have little effect Various cognitive styles of searchers were tested to find out whether they relate to search results. Only FD/Fl cognitive style were found to be significant in relation to search results. Searchers showed a variety of attitudes about online searching. They revealed sensitivity toward searching charges. The attitude toward charges was reflected on the searching behavior. The sensitive searchers tend to conduct cost-effective searches, Searching styles of intermediaries were characterized as interactive and fast batch. It was found that experienced searchers prefer simple searches which do not explore the interactive capabilities of online system. In summary, previous studies have confirmed that there are apparently great individual differences among online searchers in searching behaviors as well as attitudes. But relationships between these individual differences and search performance were too weak to be significant.
