  • The turbine flowmeter is selected for high precision and reproducibility at the time of flow rate measurement but causes various uncertainty factors of measurement in the difference between the standard environmental condition at calibration and the environmental condition at the site. Also, a reliable interpolation method is required for use in sections other than calibrated measurement values. Therefore, in this paper, in order to improve the reliability of the flow rate measurement, we designed and manufactured a device that accurately measures the output signal of the turbine flowmeter, interpolates the value of the calibrated result value, and corrects the temperature change in real time We confirmed the reliability of the measurement at the site to carry out the performance verification.

  • The present research investigated the psychological nature of low levels of trust in Korean society and the role of family expansionism, a cultural psychological factor, in this phenomenon. Specifically, we examined the possibility that Koreans' distrust toward social system is, at least partially, due to high standards for trust, which might be closely related to Koreans' cultural characteristic of family expansionism. In Study 1, the relations between levels of family expansionism, trust standards, and actual levels of trust for parents, judiciary, and politicians were examined among 540 Korean adults. In Study 2, we manipulated levels of family expansionism to examine its effect on trust standards. Results showed that trust standards were higher for politicians than parents. Participants' trust standards for politics were unrealistically high, especially on the responsibility factor. Actual levels of trust for judiciary and politicians were low when the trust standards for these targets relative to trust standards for parents were high. Moreover, the trust standards and levels of trust for judiciary and politicians (relative to those for parents) were positively correlated to levels of family expansionism. In other words, higher levels of family expansionism were linked to higher trust standards and levels of distrust for judiciary and politicians. In addition, Study 2 results showed that trust standards became high when family expansionism was induced. Unlike previous studies which focused on causes of low levels of trust while assuming that Korean society itself is a low trust society, the present research investigated the underlying mechanism behind the seemingly low trust in Korean society.

  • 본 연구는 대학의 창업교육 서비스 품질이 교육만족과 창업역량, 창업의지에 미치는 영향에 관한 연구이다. 대학에서 다양한 창업교육이 진행되고 있지만 창업성과에 대한 연구는 많이 이루어지지 않고 있다. 본 연구에서는 창업성과를 높이기 위한 요인을 분석하기 위해 창업교육의 서비스 품질이 교육만족과 창업역량, 창업의지에 미치는 영향에 대해 살펴보았다. 첫째, 창업교육 서비스 품질을 측정하기 위해 서비스 품질에 대한 이론적 배경을 바탕으로 유형성, 신뢰성, 반응성, 확신성, 공감성 등 5개 요소 21개의 문항을 설정하고, 설문 분석 결과를 바탕으로 창업교육 서비스 품질이 교육만족과 창업역량에 미치는 영향을 알아보았다. 둘째, 고객 만족에 대한 선행연구를 바탕으로 창업교육 수강생의 교육만족을 정의하고, 창업역량의 요소 중 성취역량, 창의성역량, 개념화역량, 사회적 역량 등에 미치는 인과관계를 분석하였다. 셋째, 교육만족과 창업역량이 창업의지에 미치는 인과관계를 분석하였다. 그 결과, 창업교육 서비스 품질은 기존의 연구와 다르게 유형성과 신뢰성이 하나의 요인으로 분석되어 반응성, 확신성, 공감성 등 4개 요인으로 확인되었고, 4개의 요인으로 구성된 창업교육 서비스 품질이 교육만족과 창업역량에 영향을 주는 것으로 확인되었다. 또한, 창업역량 요인을 4개로 정의하여 설문을 분석한 결과 성취역량과 창의성역량이 하나의 요인으로 분석되어 개념화역량, 사회적 역량과 함께 3가지 요인으로 확인되었다. 이는 교육만족에 영향을 받는다는 것을 확인할 수 있었다. 창업의지는 창업역량에 영향을 받았지만, 교육만족에 직접적인 영향을 받지 않는 것으로 확인되었다. 이러한 결과는 교육만족이 창업역량을 통하여 창업의지에 간접적인 영향을 미친다는 것을 의미한다. 차후 연구에서는 대상을 여러 지역 혹은 전국으로 확대할 필요성이 있으며, 다른 변수와의 접근 방법을 가지고 연구되어야 할 것이다.

  • The purpose of this study is to investigate the determinants of the quality of Web-based legal information services and their significant influences on the user continuance intentions. Based on the main dimensions of the SERVQUAL, this study conceptualizes five dimensions of reliability, assurance, design, empathy, and responsiveness. It measures the level of expectation and satisfaction on the basis of these five dimensions. Regression analysis was conducted to extract and analyze the determinants of the service quality and the factors affecting continuous intention. The level of legal information service quality is superior in empathy, responsiveness, and design category, but it is relatively insufficient in reliability and assurance category. In the reliability category, the relevance of the search results was an issue. The problems related to the authority and information sources were recognized as important. Reliability implies that there is a relatively close relationship between empathy and responsiveness, and that it is necessary to improve the quality of contents such as empathy and responsiveness in order to increase reliability. In order to increase the ongoing use of legal information services in the future, it is more effective to make sure that assurance is top priority.

  • The purpose of the present study was to examine psychometric properties of the BSI-18 in Korean adults with mental disorders. This study examined internal consistency, test-retest reliability, convergent validity, and a factor structure of the BSI. The sample consisted of 180 adults with mental disorders, who enrolled in mental hospitals and in a day hospital. Data was analysed using reliability analysis, correlation analysis, and confirmatory factor analysis. Major findings were as follows. The Korean version of the BSI showed good internal consistency and test-retest reliability, as well as excellent convergent validity. The original three-factor structure of the BSI-18, proposed by Derogatis, 2001, fitted to the data. These findings indicate that the BSI-18 is a reliable and valid measure as a psychiatric assessment tool and a treatment outcome measure.

  • The purpose of this study was to stimulate the online word-of-mouth advertising by developing the concept of word-of-mouth constraint factors and measurement tools in connection with the SNS advertising on social networks. To achieve the objective of this study, this study was conducted in 3 phases. First, the exploratory investigation(target group interview, in-depth interview, and expert interview) was performed to determine the concept and scope of the word-of-mouth constraint based on literature study and qualitative investigation method. Second, the reliability and validity of the measurement questions were verified through the survey in order to refine the developed measurement items. Third, the predictive validity of measurement items was verified by examining the relationship with other major construct concept for which the developed measurement items were different. Based on the results of study, 6 components and a total of 23 measurement questions for those components were derived. Each was called intrapersonal and interpersonal constraint(psychological sensitivity, compensatory sensitivity, and other person assessment), structural constraint(reliability, informativity, and entertainment). We developed the measurement questions related to word-of-mouth constraint based on qualitative study and quantitative study and holistically examined the social and psychological, environmental interruption factors acting as the word-of-mouth constraint factors for SNS advertising in terms of SNS achievements and evaluation from the perspective of word-of-mouth constraint. The results will lead to creation of basic framework for systematic and empirical research on the online word-of-mouth constraint and to achievement of effective SNS word-of-mouth advertising.

  • The purpose of this study is to measure teachers' beliefs to teach software education effectively. Based on the revised version of the STEBI-B questionnaire, factors influencing the software education were added through the literature review and composed of sub-factors of the category of personal software education teaching efficacy and software education outcome expectancy. And then, 146 in-service elementary school teachers were surveyed preliminary 35 questions. The collected data were analyzed by factor analysis and reliability analysis, and 5 items were deleted to complete the final item. A factor analysis and reliability analysis of the final 30 questions were conducted to demonstrate the appropriateness of the item composition, and software education teaching efficacy belief instrument(SE-TEBI) was developed.
