  • The purpose of this study was to develop a scale for the evaluation of the subjective fabric hand. In order to find out the appropriate method for the evaluation, bipolar adjectives were compared to unipolar adjectives. One hundred female university students we.e selected as judges. They assessed 9 fabrics using the 9 point scale system for both bipolar and unipolar adjectives. When using the bipola. scale, judges responded more consistently showing smaller deviation among their responses. The Judges seemed to understand the meanings of adjectives in the bipolar scale more clearly than in the unipolar scale. Unipolar scale has twice the number of questions than bipolar scale does. Therefore. judges often felt bored responding to the questions using unipolar adjectives. If the appropriate antonym can be found through verified method, bipolar scale seems to have more advantages than unipolar scale.

  • The purpose of this study was to explore the trends and core keywords of the secondary school home economics teacher selection test using content analysis and text network analysis. The sample comprised texts of the secondary school home economics teacher 1st selection test for the 2017-2022 school years. Determination of frequency of occurrence, generation of word clouds, centrality analysis, and topic modeling were performed using NetMiner 4.4. The key results were as follows. First, content analysis revealed that the number of questions and scores for each subject (field) has remained constant since 2020, unlike before 2020. In terms of subjects, most questions focused on 'theory of home economics education', and among the evaluation content elements, the highest percentage of questions asked was for 'home economics teaching·learning methods and practice'. Second, the network of the secondary school home economics teacher selection test covering the 2017-2022 school years has an extremely weak density. For the 2017-2019 school years, 'learning', 'evaluation', 'instruction', and 'method' appeared as important keywords, and 7 topics were extracted. For the 2020-2022 school years, 'evaluation', 'class', 'learning', 'cycle', and 'model' were influential keywords, and five topics were extracted. This study is meaningful in that it attempted a new research method combining content analysis and text network analysis and prepared basic data for the revision of the evaluation area and evaluation content elements of the secondary school home economics teacher selection test.

  • Research Projects allow students to experience of scientific research by conducting experiments on specific scientific subjects and writing reports. The process of research begins as students find and propose research questions and its importance has been consistently emphasized. In this study, we developed various strategies to support students to draw research questions and applied to each phase. We analyzed how students' research questions were developed at different phases. The program consists of five phases, such as (1) Exploration, (2) Literature Review and Data Collection, (3) Modification and Extension, (4) Sharing and Evaluation, (5) Final Selection and Research Plan. The program was applied to high school Research Project for 12 hours. A total of 13 students were divided into four groups of 3-4 students and conducted researches. The results of each student's research process and final research plans were then collected and analyzed. The overall quality of research questions produced by the students showed improvement in each phase. Each strategy improved in various aspects of the research questions at each level. Students were able to find their own area of interest in the 'Exploration' phase and then they began to suggest verifiable plans in the 'Literature and Data Collection' phase. They were able to find a variety of variables under the 'Modification and Extension' phase, whereas the precision of research questions improved in the 'Sharing and Evaluation' and the 'Final Selection and Research Plan' phase.

  • When teachers make up assessment questions regarding the content area that contains shapes and graphs, they should present the pictures so that their role might be represented properly. We exhibited the process of constructing shapes and graphs utilizing GeoGebra, and simultaneously analyzed the process of developing and revising questions using this and awareness changes in teachers who participate in the teacher's training focused on improving professionalism for making up questions such as CSAT(College Scholastic Ability Test). Through the survey they mentioned that making questions utilizing algebraic construction overcame the limitations of making up questions and played an instrumental role in developing creative questions. Based on the results, We suggested effectiveness of making up questions utilizing algebraic construction. Our intention was to improve the skills of teachers for making up questions such as CSAT and to suggest implications about it.

  • The proper evaluation of reference services requires qualitative approach as well as quantitative one. The quality of a reference service can be evaluated by how promptly and accurately a librarian responds to the user's questions and also by how much the user is satisfied with the librarian's overall performance in providing the answer. In this study, the reference service of an university library was evaluated by the following procedure : 1. Identification of a group of the most frequently referred Korean government publications through two pre-tests of user surveys. 2. Preparation of 130 questions of bibliographic and factual type from the above publications. 3. Selection of 30 questions which can be answered from the collection of the evaluated library. 4. Mimic requests of reference service by 5 proxies trained on the unobtrusive test method with 30 questions asked at various times of the day and on various days of the week during a period of 5 months. 5. Drawing up of response sheets (by proxies) with descriptive comments on library staffs' question administration, response, attitude, etc. 6. Preparation and coding of data tabulation sheets and final analysis. The conclusions of this study are as follows : 1. The user serveys showed that needs for the library service for government publications were great. The $80\%$ of the government publications users were visiting more than two organizations for access to information and the $37\%$ were getting information directly from the publishers. 2. The librarians of the evaluated library could give correct answers to $53\%$ of 30 (bibliographic and factual) guestions. 3. The correctness of answer was independent of the length of the time spent the librarians. The librarians' grasp of the questions and direction of approach determined the success or failure of the service. 4. The librarians relied too much on the reference library catalog which doesn't include many of the government publications of their own collection. 5. The $79\%$ of the failure of the service were due to the librarians' lack of knowledge as to the information source for government publications and the unsystematic method of approach to it.

  • In this study, we analyzed the end-of-chapter questions in 8 types of chemistry II textbooks for science teachers according to revised Bloom's taxonomy of educational objectives not only to raise interests of questions in textbooks but also acquire a basic material for using questions in textbooks effectively. The results of classification following Bloom's cognitive category showed that 'Understanding(44.7%)' level was the most, then 'Application(29.9%)', Knowledge(15.6%) and 'Analysis (9.5%)' in order, which is distinct difference from the result of classification of the end-of-chapter questions in college general chemistry books which was 'Application', 'Analysis' and 'Understanding' in order. Especially, questions of 'Evaluation' level were not found at all in any textbook investigated and 'Synthesis(0.3%)' level was very few. On the other hand, the percentage of questions in 'Understanding' and 'Executing Quantitative' which required specific algorithms was 70% of total with most of the questions in 'Application' were 'Executing Quantitative'.

  • A study was performed to develop as a screening tool the Simple Evaluation Questionnaire for Screening the Over-weight-type Dietary Pattern in 30 to 49 Year Old Adults. We used the data from the 30 to 49 year old subjects who participated in the three surveys - the health behavior survey, the dietary habit survey and the food intake survey - as the National Health and Nutrition Survey 1998. The 3,598 adults were classified into to two body fatness groups of normal (including underweight) and overweight (including obese) on the basis of their relative body weight (RBW) When comparing variables between the two groups, significant differences were found in gender, education, job, employment status, perceived health status, sadness / depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, drinking pattern (yes/no) , amount of alcoholic drinks, frequency of intoxication or drunkeness, amount of alcoholic drinks when drunk, intensity of exercise, frequency of exercise, exercise duration, skipped meals, small meals and drug supplements. In terms of food intake, there were significant differences in the daily food intake in terms of breakfast, dinner, daily kimchi and dairy products. In terms of mealtimes, we found differences in the amount of cooked rice at breakfast, kimchi at lunch, soup / kuk at dinner, fresh vegetables for snacks, fried foods for snacks between breakfast and lunch, and fruits /juices for snacks between lunch and dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis three times, we chose 10 questions for a simple evaluation of dietary patterns for the overweight-type category in order to give one point each. Among them we selected two questions to add one additional point and one question to add two additional points. The average scores of the overweight and normal groups, as shown by the developed questionnaire, were $5.97 \pm 2.36 \pm 7.36 \pm 2.21$, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 67%, 59% and 62%, respectively.
