  • The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.

  • This study examined the effects of previewing and providing background knowledge on low level EFL readers' comprehension of expository texts and their responses to these treatments. 130 college freshmen were randomly placed into one of three treatment groups and read two expository texts reflecting unfamiliar cultural information. Prior to reading, one group was given previewing instruction, which included vocabulary preteaching and summaries, and a second group was provided with culture-specific background knowledge through watching videos and slides. The third group read each text without any prereading instruction. Immediately after reading a passage, subjects answered a 10-item multiple-choice test. Results showed significant positive effects of the previewing treatment and weak positive effects of the providing background knowledge treatment. Students' responses on the questionnaires revealed that the majority felt that the experimental treatments contributed to comprehension enhancement, made reading more enjoyable, and expedited their reading process. Students in the control group, however, indicated that they needed explicit prereading instruction in order to understand the texts. Pedagogical implications of the findings for EFL reading instruction are provided.

  • As an attempt to characterize the English test section of CSAT (College Scholastic Ability Test) and to get some suggestions, this study raised the research questions, as 'What are the main factors that affect students' English test scores in CSAT, and how big influences do they have?' It has been hypothesized that among main factors are the L1 competence, represented by the Korean test scores in CSAT, background knowledge or intelligence, represented by the "total" scores in CSAT, and the two types of L2 knowledge (vocabulary and grammar on one hand and prosody m the other hand), measured by the test devised specially for this study. The individual effect of the L2 vocabulary and grammar (one kind of L2 knowledge) was 70%, that of background knowledge or intelligence 61%, that of the L1 competence 50%, and that of the L2 prosody knowledge (the other kind of L2 knowledge) 32%. According to the stepwise regression, the whole effect of these four factors was 74%. The findings suggest that first, although CSAT is based on the top-down model of comprehension, the bottom-up model of learning should be more emphasized in our English class. Also, since background knowledge or intelligence is the second most influential factor, the top-down model of learning that helps students learn to understand by activating their various schemata must also be very effective.

  • This study was conducted by extending Ajzen's Theory of Planned Behavior(TPB) model in analyzing physician's observance behavior of National Health Insurance review standards. An extended TPB model was proposed by including 'background knowledge'and 'dorganizational commitment'in original model to predict physician's review standards observance behavior. Surveys for data collection were carried out on the physicians who were working in a general hospital, clinics, specialized hospitals, local medical centers and long term care hospitals located in Daegu and Kyoung-Buk province in Korea. Two hundreds twenty copies of questionnaires were distributed and 166 physicians responded. Data were analyzed using a structural equation model. The results show that an affirmative attitude and subjective norms have significant positive effects on physicians' behavior of observing review standards. However, the effect of perceived behavioral control on intention to behavior is not significant. The organizational commitment and background knowledge have a positive effect on the intention of observance of review standards. In conclusion, because physician's observance behaviors are affected by background knowledge and organizational commitment as well as attitudes, subjective norms, hospital managements should establish a communication system to share information on the review standards among physicians and provide appropriate measures to increase physician's organizational commitment.

  • This research was performed for examining the differences of experience of sex education and the awareness of sexual abuse according to child's sex and economic background. Also the differences of sex knowledge and sexual consciousness were analyzed according to child's sex, economic background and sex education. Subjects were 425 children from two elementary schools and 10 community child centers in H city, Gyeonggi-do. The results were as follows. First, more girls thought the desirable place for sex education was home and more girls consulted sexual problems with their parents. Children from low economic backgrounds experienced sex education at school and community child centers rather than at home. Second, both boys and girls replied that sexual abuse was due to the attacker's fault but more girls than boys attributed the fault to themselves. Third, girls' sex knowledge grade was higher than boys. Fourth, boys showed a more open attitude toward heterosexual dating, and children with a low economic background showed a higher sex drive. Fifth, a high sex drive was related to low sexual knowledge, openness in dating and high sexual ethics.

  • As personal data breach reared up as a problem domestically and globally, organizations appointing chief privacy officers (CPOs) are increasing. Related Korean laws, 'Personal Data Protection Act' and 'the Act on Promotion of Information and Communication Network Utilization and Information Protection, etc.' require personal data processing organizations to appoint CPOs. Research on the characteristics and role of CPO is called for because of the importance of CPO being emphasized. There are many researches on top management's role and their impact on organizational performance using the Upper Echelon theory. This study investigates what influence the characteristics of CPO gives on the organizational privacy performance. CPO's definition varies depending on industry, organization size, required responsibility and power. This study defines CPO as 'a person who takes responsibility for all the duties on handling the organization's privacy,' This research assumes that CPO characteristics such as role, personality and background knowledge have an influence on the organizational privacy performance. This study applies the part relevant to the upper echelon's characteristics and performance of the executives (CEOs, CIOs etc.) for CPO. First, following Mintzberg and other managerial role classification, information, strategic, and diplomacy roles are defined as the role of CPO. Second, the "Big Five" taxonomy on individual's personality was suggested in 1990. Among these five personalities, extraversion and conscientiousness are drawn as the personality characteristics of CPO. Third, advance study suggests complex knowledge of technology, law and business is necessary for CPO. Technical, legal, and business background knowledge are drawn as the background knowledge of CPO. To test this model empirically, 120 samples of data collected from CPOs of domestic organizations are used. Factor analysis is carried out and convergent validity and discriminant validity were verified using SPSS and Smart PLS, and the causal relationships between the CPO's role, personality, background knowledge and the organizational privacy performance are analyzed as well. The result of the analysis shows that CPO's diplomacy role and strategic role have significant impacts on organizational privacy performance. This reveals that CPO's active communication with other organizations is needed. Differentiated privacy policy or strategy of organizations is also important. Legal background knowledge and technical background knowledge were also found to be significant determinants to organizational privacy performance. In addition, CPOs conscientiousness has a positive impact on organizational privacy performance. The practical implication of this study is as follows: First, the research can be a yardstick for judgment when companies select CPOs and vest authority in them. Second, not only companies but also CPOs can judge what ability they should concentrate on for development of their career relevant to their job through results of this research. Cultural social value, citizen's consensus on the right to privacy, expected CPO's role will change in process of time. In future study, long-term time-series analysis based research can reveal these changes and can also offer practical implications for government and private organization's policy making on information privacy.

  • 최근 국내에서도 지식경영과 관련한 연구와 실례가 다수 발표되고 있다. 그러나 지식경영의 이론적 배경을 완전히 이해하지 못한다면, 이를 지식창출(Knowledge creation)을 지원하는 경영도구(Managerial application)로 이해하기 보다는 정보를 관리하는 또 다른 방법으로 오인하기 쉽다. 이에 본 논문에서는 지식경영이 최근 주요 경영도구로 회자되고 있는 배경을 당대의 경영환경 및 과학철학(Philosophy of Science)을 중심으로 살펴본다. 이후 데이터(Data) 및 정보(Information)와 비교되는 지식의 특성을 고려하여 이를 창출하거나 이의 흐름(Flow)을 활성화(Facilitating)하기 위한 여러 가지 방안 중 연성정보시스템 방법론(Soft Systems Methodology)을 고찰해 본다. 연성정보시스템 방법이 건설경영(Construction Management)관련 대학교육과 실무에 어떻게 접목될 수 있는지에 관한 논의로 결론을 맺는다.
