This study analyzes ways to detect protest responses (hereafter, PR zero-bid) in the contingent valuation method (CVM). In order to distinguish PR zero-bids from true zero-bids (non-PR zero bids), this study adopts the concept of the implicit willingness to pay employing the Hicksian compensating surplus and the Taylor's 1st order approximation. When a respondent proposes a zero-bid (i.e., WTP=0) and chooses a PR filtering item to indicate that her implicit WTP is not necessary zero, her response is identified as a PR zero bid. PR filtering items falling into the PR zero bids category include the uncertainty of information, distrust in the government and project achievement, disagreement to project plans, discontent with the fairness of public works and their payment method and animosity against the CVM itself. The empirical analysis shows that PR zero bids take place systematically in particular respondent groups: respondents who have never used similar facilities before nor plans to use the facility provided by the public project, the employed, and low income groups. In conclusion, the study suggests that a CVM questionnaire needs to be designed carefully to minimize problems associated with PR zero bids and the potential risks of having sample selection bias should be concerned.

As the deployment of digital learning environment has been accelerating in rapid changes in information and communications technology, a tool is required to practically measure and evaluate the level of information education (IE) for freshmen in the University in order to propose an appropriate direction of IE in a teachers college. According to such current trends, ICT literacy is a tool to assess a specific level of capabilities such as a variety of real-world problem-solving skills, creativity, critical thinking, analytic reasoning, and communication skills. This study has developed a test tool to measure ICT literacy competence on the basis of the concept of test questions defined from the previous research. It was used to measure ICT literacy competence of 360 university freshmen of education and analyze if there is a difference among them depending on overall ICT literacy levels and genders, content areas, competence factors, and completion of IE course in high school. The result of this study would be expected to determine the current location of IE for freshmen in the University of Education and to be able to take advantage of basic data of the direction for IE course that university students need to essentially acquire in preparation for the coming future.

This study was to develop new psychological capital scale for high school students attending a technical high school specialized in invention and patent education, and to examine validity and reliability of the new psychological capital scale. Of the 400 high school students attending a technical a technical high school specialized in invention and patent education in a Province, Korea, 388 completed and returned the questionnaires. PCQ (Psychological Capital Questionnaire)-24 items version was modified to measure psychological capital of them. By conducting confirmatory factor analysis, the final 19 items were selected. The Cronbach's alphas of the final version were ranged from .723 to .871. Convergent validity was supported through correlations among the sub-scales of the final version of PCQ, creative intelligence, creativity, and academic efficacy. Criterion-related validity was supported by mean differences on 4 sub-scales of psychological capital (i.e., self-efficacy, hope, resilience, and optimism) between two groups (i.e., prize-winning experiences for invention or academic achievement).

The purpose of this study is to analysis of the difference between dementia policy perception, dementia knowledge, dementia attitude and dementia prevention behavior of middle-aged. The subjects were 217 middle-aged in their 40 to 64 years old who lived in D and G cities. The mean sore of were dementia policy perception 75.42±8.52, dementia knowledge 8.71±1.90, dementia attitude 28.55±5.10, dementia prevention behavior 27.04±3.35. Dementia knowledge were significant differences in gender, number of diseases, source of dementia information. Dementia attitudes were significant differences in gender, age, education, dementia in family, dementia living together, job status, early examination, source of dementia information. Dementia prevention behavior were significant difference in dementia living together and early examination. The most category of dementia prevention behavior was 'cigarette smoking(Inverse question)', and blood pressure and diabetes management' were the lowest. Therefore, development of a professional and systematic dementia education program to raise the awareness of dementia policy among middle-aged adults and form the right dementia knowledge and positive dementia attitude. Development of customized dementia prevention behavior programs to maintain cognitive activities, social activities, proper eating habits, and health care is needed.

Although Attention Deficit Hyperactivity Disorder(ADHD) has been considered as the disorder occurring during childhood, the prevalence is increasing among adolescents and adults. The prevalence rate varies from 2.0 to 14.3% due to the difference of diagnostic criteria, different assessment methods, or subjects' age difference. Therefore, it needs to make age specific(i.e., for children, for adolescents, and for adults) assessment tools. Authors translated Conners-Wells Adolescents Self-Report Scales(short form)[CASS(S)] in to Korean to get validity and reliability as a way of development of assessment tool for adolescent with ADHD in Korea. CASS(S) was translated and corrtected by three psychiatrists and one clinical psychologist. To examine the concurrent validity and test-retest validity, CASS(S) was applied with K-YSR on one class of each grade in a middle school in Seoul with two week interval(total 115：male 58, female 57). To test validity, authors analysed and got Cronbach's as internal consistency. Construct validity was done by principal axis factor analysis on 4,354 students. As a result, Cronbach's alpha for internal consistency was .88, Pearson coefficient for test-retest reliability .83, and coefficient for concurrent validity .65. And in the factor analysis to examine construct validity, three factors were revealed as cognition, hyperactivity, and conduct. These results shows that CASS(S) may be useful tool for adolescents with ADHD, although there was a limit not to be done the comparison with clinical groups.

The Q&A service of the official Korea Astronomy and Space Science Institute (KASI) webpage was installed in 2000 and have been actively used since then. In this paper, we analyze the questions asked through the Q&A service and the number of inquiries with the aid of statistical methods. We also study the contents of the questions. Specifically, we have created statistics of questions and inquiries that go monthly and yearly, and have developed categories to analyze the characteristics of questions in regards to their cognitive aspects. Each question is categorized into two elements based on their recognitive aspect: science knowledge or science study. Each element also has sub-categories that help readers understand the characteristics of the questions. For the analysis, we used a sample consisted of questions from July to December, 2004. Through this study, we achieved a better understanding of the questions asked by the Q&A service. We are planning to improve the quality of the Q&A service by extending the size of the FAQ(frequently asked questions). Throughout this study, we find that the number of questions are increasing with time, and the overall quality of the questions is improving. As we expect the number of people using our Q&A service to increase and the questions to get more difficult to answer, development of improved content is required.

In this study, we investigated how 'Scientific Inquiry Experiment,' a newly introduced subject under the 2015 revised curriculum, was implemented to identify the difficulties that science teachers face in the process of teaching the subject and to explore how to support them through online survey and interview methods. A questionnaire of the survey, which consisted of environmental factors of class, preparation and execution of class, teacher self-evaluation of class, and direction for the subject, was developed, and the online survey was requested with a response from one teacher per school from 1674 high schools nationwide. We analyzed the results from 814 teachers who answered all required questions, and we also conducted interviews and online advisory discussions to ensure the validity of our analysis. In the results of the study, teachers complained of lack of time for preparation and execution of the subject, and they demanded laboratory assistants and quality teaching materials. In addition, in order to achieve the goal of the subject, they agreed the necessity of using the 'block scheduling' though they also agreed the difficulties of its implementation. Meanwhile, the alteration of guidelines for evaluation, which was changed from 9-grade system to 3-grade system, was positively recognized by teachers. As a result of this change, the percentage of performance assessment increased in 2019 compared to 2018, but there were no significant changes in the number of 'hands-on activity.' Finally, we proposed ways to support 'scientific inquiry experiment'.

The purpose of this study is to find out the actual status of the math after-school program in the elementary school and the content of the program. We survey the 115 math external math lecturers of the 100 elementary schools in Busan and analyze the results. Research questions are set as follows. 1. What is the status of the elementary math after-school? 2. How is the content of the program of the elementary math after-school? The results of the survey are analyzed as follows. First, any of the external math after-school lecturer did not major in math education and 87% of them majored in another discipline. Second, 47% of the external math after-school lecturers are employed by privately-held companies. Third, 64.4% of the content of the after-school programs is the supplement and deepening of the regular math class. Fourth, 76.5% of the time of the first class of the math after-school program is 50 minutes and 46% of the math after-school opens 5 classes per a week. Fifth, most programs consist of the problem-solving style class. Sixth, it is difficult to run the math after-school according to students' level and grade. Based on the above discussion, I suggest the following. First, math after-school class should be the action-oriented class to motivate the positive and interested participation of the students. Second, lecturer training and various math class programs is required to improve the quality of the math after-school class.

This study was carried out in order to offer basic data available for forming the better oral health habit by closely examining a cause for industrial workers' tooth loss. It analyzed correlation in missing teeth with general characteristics, subjective oral health recognition, habit related to oral health, and oral symptom targeting 6,976 of production workers and office workers who work at 49 industrial places where are located in Gumi city of Gyeongsangbuk-do Province from June 1, 2009 to December 31, thereby having obtained the following conclusions. 1. The higher age group led to the higher ratio of missing teeth. The ratio of missing teeth was lower in a case of having been removed plaque than having not been removed plaque. 2. The ratio of missing teeth was high in a case of having dental caries and periodontal disease. The ratio of missing teeth was high in a case of having smoked in the past or in a case of smoking now. 3. The ratio of missing teeth was high in a case of having less toothbrushing frequency and in a case of not using dental floss or interdental brush. 4. The ratio of missing teeth was high when a tooth is throbbing and when tongue and cheek are throbbing in addition to pain and bleeding in gum. 5. The ratio of missing teeth was high in a case of having unpleasant bad breath. The above results are expected to be likely conducive to offering basic data necessary for developing the oral health educational program for industrial places that can promote and maintain workers' oral health, and for improving oral health program and system available for promoting and maintaining workers' oral health hereafter.
