  • Relevance judgment is important in terms of improving the effectiveness of information retrieval systems, and it has been dominant for users to search and use images utilizing internet and digital technologies. However, in the field of image retrieval, there have been only a few studies in terms of identifying relevance criteria. The purpose of this study aims to identify and characterize the non-relevance criteria from the failed image searches. In order to achieve the purpose of this study, a total of 135 participants were recruited and a total of 1,452 criteria items were collected for this study. Analyses and identification on the data set found thirteen criteria such as 'topicality', 'visual content', 'accuracy', 'visual feature', 'completeness', 'appeal to user', 'focal point', 'bibliographic information', 'impression', 'posture', 'face feature', 'novelty', and 'time frame'. Among these criteria, 'visual content' and 'focal point' were introduced in this current study, while 'action' criterion identified in previous studies was not shown in this current study. When image needs and image uses are analyzed with these criteria, there are distinctive differences depending on different image needs and uses.

  • In this paper, we examined informatics textbooks for middle school students in accordance with 2009 revised curriculum through conducting both content analysis and surveys. The content analysis was analyzed the composition and contents of textbooks. Survey questionnaires were based on the authorization criteria and selection standards of informatics textbooks. The content analysis demonstrated that there were discrepancies among textbooks in areas such as the total number of pages, related material, the number of core concepts introduced in each chapter, and the application of software. The survey results showed that two sections - 'Expression and Modification' and 'Text' exhibited the most positive results, and the 'Creativity' section the least. Using the findings above, we present alternative ways to improve qualities of these textbooks.

  • The purpose of this study was to develop and present the accreditation criteria for engineering technology education programs in junior colleges. Research methods used in this study were review of related literature, experts discussion, and Delphi technique. Especially, Delphi technique was the major research method of this study. The Delphi surveys were taken for about seven weeks and three rounds at a higher level of expert participation. Major results of the study were as follows: 1. It proved that thirty six of total forty items had the content validity as the accreditation criteria of engineering technology education programs for junior colleges. CVR(Content Validity Ratio) of four items were below .33 and eliminated four items from the final accreditation criteria. 2. It proved that total Cronbach ${\alpha}$ was very high .9142 and reliability was very high all over items. It proved that six items made worse reliability, therefore it was desirable to exclude six items for increase of reliability. But the final accreditation criteria included six items, because they had a high validity as well as increasing rate of Cronbach ${\alpha}$ was very low with the exception of them. 3. Items of high importance were drawn out through analysis of importance. It proved that thirty of total forty items were more than 4.00 average in importance and ten items were less than average. 4. In conclusion, the final accreditation criteria were developed and presented through such analysis of validity, reliability and importance. The final accreditation criteria for engineering technology education programs in junior colleges were composed of seven domains of educational objectives, learning outcomes, curriculum, staff, facilities, institutional support, and student assessment.

  • For STEM education science teachers usually choose topics which are related to both science and other disciplinary contents. Nevertheless it is not clear for the teachers to adopt what kind of criteria for their choices. Interdisciplinary teaching is not a mixture of science content with another one from different disciplines as resources for the content teaching. Instead the criteria and perspectives for the integration need to be clearly defined. In this study we investigated how to integrate science and other disciplines in terms of interdisciplinary teaching. Family resemblance approach by Wittgenstein, recently revised by Erduran and Dagher, was applied to comparative analysis of science, math, and physical education curriculum documents in Korea. Aim and value, methodological rules and methods, knowledge, and activities in each discipline were compared and analyzed with the view of FRA. Results of the study described alternative criteria of how to find appropriate topics for interdisciplinary teaching.

  • The purpose of this study is to construct the fundamental data for setting a valid viewpoint as the base of landscape planning and management practices. To do this, we analyzed the preceding dissertations and landscape plan reports which presented the selection criteria of viewpoint. 37 research samples containing the criteria of viewpoint were investigated. The selection criteria and trends of viewpoint were analyzed as follows : Firstly, by analyzing the preceding researches we were able to grasp the criteria that had been used to set viewpoint. Secondly, we investigated the differences in criteria of selecting the viewpoint according to the research type, research time and view object. Finally, we analyzed the trends of viewpoint selection criteria and classified the characteristics and selection criteria of viewpoint based on an overview of the research content. It can be concluded that the criteria of viewpoint are intimately linked to the view object, the purpose and role of viewpoint which is related to the landscape planning and management practices. According to this study, we can find that the selection criteria and trends of viewpoint have been used in the research related to the view plane following the 1990's. Hereafter, additional research and the comparisons with researches abroad is necessary to set the objective selection criteria of viewpoint.

  • The Web is an important source of information for health care consumers, and the resources they find on the Web have a direct affect on their health outcomes. Despite the enormous benefits of online health care, the quality of health information on the Internet is an area of increasing concern. Therefore, there's a need to develop quality assessment tools that can filter out poor quality online health information. The purpose of this study is to explore the critical attributes for assessing website quality and for developing quality assessment measurements. We completed three focus group discussions with 24 participants that were administered by a moderator and based on specifically focused group questions. The results suggest that the most important quality criteria, as identified by the respondents, were related to issues of credibility and accuracy. To determine the credibility of Internet health information, the respondents stated one must consider the following: the information source, disclosure of the author's or organization's credentials/qualifications, disclosure of ownership and the updating of the content. For the accuracy of content, elements such as a statement of purpose, evidence-based information, relevance and completeness should be considered. Interactivity, accessibility, and design were additional quality criteria.

  • Two marker compounds of Achyranthis Radix, ecdysterone and inokosterone, were analyzed by HPLC on an ODS column ($250{\times}4.6$ mm, 5 ${\mu}m$) with a mobile phase of 15% acetonitrile containing 0.08% formic acid at a flow rate of 1.0 mL/min and a detection wavelength of UV 254 nm. The method was validated by ICH guideline and applied to the monitoring of marker compounds in 93 samples of Achyranthis Radix collected at various areas in Korea and China. The new content criteria of ecdysterone and inokosterone, established using linear regression method were 0.033% and 0.020%, respectively. When the new content criteria were applied to the quality control test of commercial Achyranthis Radix, 95.4% of total samples including 100% of Korean and 92.6% of Chinese samples were passed the test. Application of new content criteria could protect the Korean products and decrease the distribution of Chinese products with lower quality.
