This study examined 12 types of towels with differing fabric material, function, quality, printing, pile length, twist, etc. from a towel company which manufactures and distributes products domestically. After 3 months of use by consumers, a consumer satisfaction survey was administered and results analyzed. Four types of towels were assigned to each group and the towels were used every day for 3 months. Participant feelings after using the towel for the first time and after using it for three months were investigated. The questionnaire consisted of 26 questions on a 5-point Licket-type scale. The first 13 questions measured perceptions of absorption, touch, fine fiber loss, contamination, deformation, drying speed, and design. Other questions compared differences between the two towel types in terms of their material, function, quality, printing, pile length, and degree of twisting. Results showed that, with regards to weight, consumers preferred towels between 130~150g and a thickness of around 1.7~1.8mm. The bamboo towel was considered superior to the cotton towel in terms of sense of touch and did not happen linter after washing. The antibacterial towel was considered better than the cotton towel in terms of absorption but in terms of contamination, participants felt the antibacterial towel became dirty more easily than the cotton towel. We thought that it might be influence of the color of towel. Low-quality towels became stiffer and misshapen more easily than higher-quality towels. But the study showed that the consumers did not perceive significant differences in the towels' quality. Printed towels became thinner and their color changed more with washing. The consumers preferred the design of jacquard towels to printed towels. Towels with short piles was happened more linter than the towel with long pile after washing. Non-twisted towel were better than the highly-twisted towel in terms of sense of touch and absorption but the non-twisted towel happened more linter after washing and became dirty more easily.

Background: Common questions about shoulder arthroplasty (SA) searched online by patients and the quality of this content are unknown. The purpose of this study is to uncover questions SA patients search online and determine types and quality of webpages encountered. Methods: The "People also ask" section of Google Search was queried to return 900 questions and associated webpages for general, anatomic, and reverse SA. Questions and webpages were categorized using the Rothwell classification of questions and assessed for quality using the Journal of the American Medical Association (JAMA) benchmark criteria. Results: According to Rothwell classification, the composition of questions was fact (54.0%), value (24.7%), and policy (21.3%). The most common webpage categories were medical practice (24.6%), academic (23.2%), and medical information sites (14.4%). Journal articles represented 8.9% of results. The average JAMA score for all webpages was 1.69. Journals had the highest average JAMA score (3.91), while medical practice sites had the lowest (0.89). The most common question was, "How long does it take to recover from shoulder replacement?" Conclusions: The most common questions SA patients ask online involve specific postoperative activities and the timeline of recovery. Most information is from low-quality, non-peer-reviewed websites, highlighting the need for improvement in online resources. By understanding the questions patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes. Level of evidence: IV.

This study used a Chatbot, a generative artificial intelligence (AI), to analyze the interaction between the Chatbot and students when exploring critical minerals from an epistemological aspect. The results, issues to be kept in mind in the teaching and learning process using AI were discussed in terms of the role of the teacher, the goals of education, and the characteristics of knowledge. For this study, we conducted a three-session science education program using a Chatbot for 19 high school students and analyzed the reports written by the students. As a result, in terms of form, the students' questions included search-type questions and non-search-type questions, and in terms of content, in addition to various questions asking about the characteristics of the target, there were also questions requiring a judgment by combining various data. In general, students had a questioning strategy that distinguished what they should aim for and what they should avoid. The Chatbot's answer had a certain form and consisted of three parts: an introduction, a body, and a conclusion. In particular, the conclusion included commentary or opinions with opinions on the content, and in this, value judgments and the nature of science were revealed. The interaction between the Chatbot and the student was clearly evident in the process in which the student organized questions in response to the Chatbot's answers. Depending on whether they were based on the answer, independent or derived questions appeared, and depending on the direction of comprehensiveness and specificity, superordinate, subordinate, or parallel questions appeared. Students also responded to the chatbot's answers with questions that included critical thinking skills. Based on these results, we discovered that there are inherent limitations between Chatbots and students, unlike general classes where teachers and students interact. In other words, there is 'limited interaction' and the teacher's role to complement this was discussed, and the goals of learning using AI and the characteristics of the knowledge they provide were also discussed.

Objectives : The purpose of this study is to evaluate if the answers of questionnaires correlate with real body shapes and to evaluate if there are any differences between different types of questionnaires. Methods : We hand-measured body circumferences and body widths to analyze statistically answers of 9 questions from 2 different questionnaires. Also we compared two different types of questionnaires with Pearson product-moment correlation coefficient and two way ANOVA test. Results : There are significant correlations between answers of questions and all measured body circumferences and most body circumferences except for iliac width. Also answers of questionnaires even about the same chest part are not quite the same according to the opposite type of questionnaire after we compared grouping two of eight questions. Patients seem to have difficulty to recognizing if their necks are well-developed or not especially when the question asks about body shape when comparing two parts such as neck vs waist or chest vs buttock. Conclusions : There is general tendency of recognizing one's body shape properly. But also there are differences of recognition according to the type of questionnaire about the same body. So it is recommended to study more about the questionnaires.

We investigated the perception and preferred type of question and analyzed type of questions asked by teachers in elementary science class to identify how teachers' perception of questioning is reflected in teaching practices. We collected the data from questionnaires, deep-interview and audiotaped four classes from grade 3 and six classes from grade 6. The data form deep-interview were analyzed interpretively and Blosser' framework of question was used to analyze questions which teachers used in classes. By interpretation of data from questionnaires, the teachers agreed that questioning affects science class in elementary school. There were a little differences in perceptions of questioning among three teachers. They preferred various types of question rather than a specific type. They didn't have a good understanding of questioning. The result showed that the teachers used frequently cognitive-memory question and convergent thinking question, which belonged to closed questions in their science classes. This didn't accord with their preferred types of question. The causes came from objectives of science instruction, degree of understanding about questioning, preference and confidence for science class. From this findings, we suggested that teachers should be given opportunities to take training courses in questioning in order to use effective questioning in science class.

Background: This study analyzed questions searched by rotator cuff patients and determined types and quality of websites providing information. Methods: Three strings related to rotator cuff repair were explored by Google Search. Result pages were collected under the "People also ask" function for frequent questions and associated webpages. Questions were categorized using Rothwell classification and topical subcategorization. Webpages were evaluated by Journal of the American Medical Association (JAMA) benchmark criteria for source quality. Results: One hundred twenty "People also ask" questions were collected with associated webpages. Using the Rothwell classification of questions, queries were organized into fact (41.7%), value (31.7%), and policy (26.7%). The most common webpage categories were academic (28.3%) and medical practice (27.5%). The most common question subcategories were timeline of recovery (21.7%), indications/management (21.7%), and pain (18.3%). Average JAMA score for all 120 webpages was 1.50. Journal articles had the highest average JAMA score (3.77), while commercial websites had the lowest JAMA score (0.91). The most commonly suggested question for rotator cuff repair/surgery was, "Is rotator cuff surgery worth having?," while the most commonly suggested question for rotator cuff repair pain was, "What happens if a rotator cuff is not repaired?" Conclusions: The most commonly asked questions pertaining to rotator cuff repair evaluate management options and relate to timeline of recovery and pain management. Most information is provided by medical practice, academic, and medical information websites, which have highly variable reliability. By understanding questions their patients search online, surgeons can tailor preoperative education to patient concerns and improve postoperative outcomes.

인터넷이 교육분야에도 활발히 사용되면서 자료검색부터 동영상 강의 나아가 인터넷을 통해 실시간으로 시험을 치르고 있다. 웹을 이용한 원격시험에 출제되는 문제들은 대부분 고정출제나 문제은행방식을 이용한 무작위 출제방식을 사용하고 있다. 본 논문의 문제은행시스템은 마크업 언어를 모르더라도 문제를 제작할 수 있으며, 웹 상에서 시험을 치르고난 후 정답률에 기초하여 난이도를 자동으로 재조정할 수 있다. 또한 학습자는 시험이 끝난뒤 피드백 학습을 할 수 있으며, 학습 후에는 학습자가 스스로 난이도를 조정하여 재시험을 치를 수 있게 하였다. 자동난이도 출제 방식은 출제가 간편해지며 평가의 예상평균점수를 미리 예측하고 시험결과가 계속 문항마다 누적되어 이를 바탕으로 출제되는 문제가 너무 쉽게 또는 너무 어렵게 출제되는 것을 막을 수 있다. 또한 원격시험은 대리시험 등 부정의 소지가 많아 유형이 다른 문제를 출제하게 되는데 여기서 오는 형평성 문제를 극복할 수 있게 된다.
