  • The risk assessment (safety assessment) must be performed to verify the risks during operation and installation of the hydrogen system and to ensure safe design and operation. Among them, hazard and operability study (HAZOP), a qualitative risk assessment, is most often used to discover risk factors and secure safety. However, in HAZOP performance, there is a difference in the level of evaluation results depending on the level and experience of the evaluator, and there is a high possibility that subjective results will be derived. This study aims to develop a risk factor library that can list and provide information on potential risk factors in order to solve these problems when performing HAZOP, reduce risk factors that are omitted or overlooked.

  • Background: Mobile applications (apps) on dietary supplements can increase consumers' access to information. However, it can lead to indiscriminate use of dietary supplements. This study aims to systematically review dietary supplement apps released in English and Korean and evaluate the quality of those apps. Methods: Through the app stores, apps on dietary supplements were systemically searched and examined. Two independent evaluators evaluated the apps and presented a mean score using the Mobile App Rating Scale (MARS). The correlation between MARS scores, user and evaluator ratings, and the number of secondary features of the apps were analyzed. Results: Of the 2,772 dietary supplement apps identified, 17 apps were included according to the selection criteria. The mean MARS score was 3.28 (standard deviation: 0.29) out of 5. Apps had higher scores in aesthetics and functionality dimensions, while engagement and information dimensions had lower scores. There was a positive correlation between the number of app downloads and information among MARS dimensions. The subjective evaluation also correlated with the information dimension. There was a positive correlation between the secondary features of the apps and MARS total score as well as the engagement dimension. Conclusion: The dietary supplement apps need to be managed at a higher level of quality to provide safe and reliable information to consumers. Especially, quality on information and engagement dimensions can be improved. Involvement of healthcare professionals in the app development, management with adequate referencing of information, and use of secondary features for enhanced user engagement can be helpful.

  • Objective: The study examined the validity and reliability of tele-assessment of cervical range of motion (ROM) through video conferencing. Design: A cross-sectional study Methods: The study included 22 healthy adults as subjects and 10 physical therapists as evaluators. The subjects underwent both face-to-face and tele-assessment of cervical ROM. The CROM (Cervical Range of Motion) device was used for reference measurements in the face-to-face assessment. The evaluators assessed the subjects' ROM through visual inspection (VI) and using a Universal Goniometer (UG) in the tele-assessment. Results: The results showed a significant correlation between the face-to-face and tele-assessment measurements for all ROM contents. The correlation coefficients ranged from r=0.54 to 0.71 (p<0.05), indicating concurrent validity. In terms of inter-rater reliability, the ICC values for both VI and UG assessments in the tele-assessment were high, with ICCs of 0.93 and 0.92, respectively. Additionally, the study investigated the usability of the tele-assessment method and environment. The satisfaction of the participants and evaluators was assessed using the Telehealth Usability Questionnaire (TUQ), which evaluates perceptions, usability, and satisfaction with telehealth services. Conclusions: In conclusion, tele-assessment of cervical range of motion using video conferencing was valid and reliable. Also, investigated participant and evaluator satisfaction and opinions, providing insights into the clinical value of tele-assessment. It is important to note that the study was conducted only healthy adults, and further research may be needed to validate the tele-assessment method in populations with cervical dysfunction or neck pain. These findings support the potential effectiveness of telerehabilitation services in assessing and managing musculoskeletal disorders.

  • Objective : This study aims to assess the potential of utilizing large language models in pattern identification education by developing a simulated patient with fatigue and dual deficiency of the heart-spleen pattern. Methods : A simulated patient dataset was constructed using the clinical practice examination module provided by the National Institute for Korean Medicine Development. The dataset was divided into patient characteristics, sample questions, and responses, and utilized to design the system, assistant, and user prompts, respectively. A web-based interface was developed using the Django framework and WebSocket. Results : We developed a simulated fatigue patient representing dual deficiency of the heart-spleen pattern through prompt engineering. To make practical tools, we further implemented web-based interfaces for the examinee's and evaluator's roles. The interface for examinees allows one to examine the simulated patient and provides access to a personalized number for future access. In addition, the interface for evaluators included a page that provided an overview of each examinees' chat history and evaluation criteria in real-time. Conclusion : This study is the first development of an educational tool integrated with a large language model for pattern identification education, which is expected to be widely applied to Korean medicine education.

This study was conducted by 2 sections. Ist section was to find out the present condition of clinical practice to 42 directors of nursing collegd and data were collected July 8 to September 30, 1988. 2nd section wat to develop a scheme on the efficiency of clinical practice for nursing education and subjects were nursing professors 258: and clinical nurses 223 in 42 junior nursing colleges their clinical settings in korea. So total subjects were 481. Data were collected july 8, 1988 to June 30, 1988 and were analysed to get the mean, standand deviation, frequency, percentage, t-test, x-test used by SPSS - pc. Major findings were as follows: 1. The present condition of clinical education in junior college of nursing in Korea. 1) 32 colleges (76.2%) were managed by a-yeas system. 2) 25 colleges (59.5%) were performed by individual practice for each subject. 3) 4 weeks interval between class education and clinical education was a major type among total colleges(36.6%, J5 colleges) 4) 30 colleges (71.4%) provided clinical education for all subjects that should be practiced. Nursing administration wes not practiced in 5 colleges (41.9%) among the remainder(12 colleges). The main cause that all practice subjects were not practiced was the lack or absence of suitable clinical settings(8 colleges. 66.7%) 5) 18 colleges (42.9%) responded that a clinical educator was, subject-charged professor. 6) 12 colleges (29.3%) responded that a clinical instructor was in charge of 6~10 students. 7) The evaluation ration ratio(professor to head nurse) by each evaluator was mostly 50% to 50 % and 60% to 40%, respectively 11 colleges(27.5%) The most common evaluation methods were evaluation by head nures, report, presence, conference (11 colleges, 27.5%) 8) The field carrier of professor was mostly 2 years (79 persons, 20.7%) and mean was 3.2 years. The education carrier of a professor was mostly over than 6 years (261 persons, 66.4%) and mean was 9.2 years. The charge hours per-week of a professor were mostly 16-18 hours (16 persons, 131.8%) 9) 34 colleges (82.9%) approved that clinical practice hour was class hour and 18 colleges (43.9 %) counted that 2 hours of clinical education equaled 1 hour of class education. 2. A study 'on the efficiency of clinical practice for nursing education. L) general characteristics of subjects were as follows: kung-sang province (145 persons, 30.5%), 30-34 years (190 persons, 39.8%), graduated degree (245 persons, 51.5%), 6-10 years of carrier (199 persons, 41.4%) were the majority. 2) suitable clinical setting was responded the systematic ward with responsible clinical educator by 210 persons(43.8%) The response by working field of subjects showed a significant difference (p< 0.01) 3) 259 subjects (54.0%) responded that the desirable qualfication of clinical instructor was 3-5 years of clinical experience with master degree or higher. 4) The mean score of desirable quality degree of clinical instructor was 3.43 professors, score (3.54) was significantly higher than clinical nurses' (3.28) (p<0.01) 412 subjects (86.0%) responded that the insufficient guality of instructor was improved by continuing to seek more new information in reference. 5) 196 subjects (41.4%) responded that desirable qualification of head nurse was more than 2 years of head position among 5 years of clinical experience. The response by working' field of subjects showed a significant difference (p<0.05) 6) The mean score of desirable quality degree of head nurse was 3.18 Clinical nurses' score(3.38) was significantly higher than professors' (3.01) (p<0.01) 419 subjects (87.8%) responded that the insufficient of head nurse was improved by continuing relationship with instructor and being responsible from planing of clinical education. 7) The mean score of performance level of the desirable clinical education guide incollege was 2.91 Professors' score (2.96) was significantly higher than clinical nurses' (2.84) (p<0.01) 340 subjects (71.1%) responded that the possible resolution for poor performance was the more specified syllabus of clinical education and the satisfiable orientation for students. 8) The mean score of performance level of the desirable clinical education guide in hospital was 3.03 9) 141 subjects (29.6%) responded that the desirable clinical evaluator was the group of professor, head nurse, staff nurse. Response by working field of subjects was a significant difference (p< 0.05) 10) The mean score of performance level of the evaluation content needed in clinical education was 3.50 Clinical nurses' score (3.56) was significantly higher than professors' (3.45) (p<0.01) 11) 433 subjects (90.2%) responded that6 desirable evaluation method for clinical education was the presence. 12) The mean score of performance level about how personal difference among clinical educators was minimized was 2.89 and response by working field of subjects was not significant. The cause of poor performance was too much workload at clinical settings and too many students st colleges by 386 subjects (81.1%).

  • The purpose of this study is to develop a Science Ethicality Test (SET) to measure students' science ethics. To secure the validity and reliability of the SET, the authors have applied Rest's Four Components Model (FCM). To develop the SET, authors have conducted the following procedures: analysis of the Korean Youth Moral Test (Kim & Lee, 2012), alteration of the KYMT; and development of the SET. Rest's FCM is consisted of moral sensitivity, moral judgment, moral motivation, and moral character. The SET is consisted of ethical sensitivity, ethical judgment, ethical motivation, and ethical character with each factor having its own elements. To secure the validity and reliability of SET, authors requested a validity assessment from five experts (two evaluators are science education experts, two others are ethics education experts, and one evaluator is a scientist), and surveyed 599 elementary school students. As a result, SET proved high levels of validity and reliability.

  • The purpose of this study is to explore the effect of responsive teaching on students' productive argumentation practice. The participating students predicted the results of an activity to measure in which location on the body (the head, spine, or back of the hand) they would feel a cellphone's vibrations faster. They then engaged in the activity and built an argument to justify it. We interviewed the teacher to understand her thoughts regarding what was expected in the class. We also recorded and transcribed the class and the interview, for use in the analysis of the students' epistemological framing and the teacher's responsive practice in small group argumentation. We discovered that the teacher intervened in the groups with questions that elicited students' thoughts as starting points for her responsive practice. Her eliciting questions led the students to talk about their ideas, supporting their engagement in the argumentation. The teacher's understanding of the argumentation lesson and her behavior to understand the students' ideas reflected her productive framing, which led her to elicit students' ideas and to support their active interaction during the small-group argumentation. She presented rebuttals against students' ideas, engaging in the argumentation as another participant, not as an evaluator. This supported the equality of intellectual authority in the group and showed students how to engage in the argumentation, supporting students' productive framing. As a result of these responsive teaching practices, the students shifted their epistemological framing, resulting in productive argumentation practice. The results of this study will contribute to developing teachers' responsive teaching strategies to support students' productive framing in science classrooms.

  • The purpose of this study was to explore students' argumentation in perspectives of epistemology and psychology and to find out how teacher can promote students' abilities of developing argumentation. The 60 hours of lessons from the interaction between one science teacher (Mr. Physics, who had 35 years of teaching experience) and his 26 students were observed, transcribed, and analyzed using two different analyzing tools; one is from the perspective of epistemology and the other from the perspective of psychology, which can portray how argumentation is constructed. Mr. Physics created the environment where students could promote the quality of scientific argumentation through explicit teaching strategy, Claim-Evidence Approach. The low level of argumentation was portrayed through examples from students' prior knowledge or experience in the form of an Appeal to the instance operation and the Elaboration reasoning skill. Students' own claims were developed through application of knowledge in a different context in the form of an Induction operation and Generativity reasoning skill. Higher level of argumentation was portrayed through Consistency operation with other knowledge or experience and Explanation reasoning skills based on students' ideas with more active teacher's inputs. The teacher in this study played a role as a helper for students to enact identities as competent "sense makers," as an elaborator rather than evaluator to extend students' ideas, and as a mentor to foster and monitor the students' development of ideas of a higher quality. It is critical for teachers to understand the nature of argumentation, which in turn is connected to their explicit teaching strategy with the aim of providing opportunities where students can understand the science enterprise.

  • The purpose of this study is to suggest directions to improve engineering education and the assessment system of our country. For this object, the present situation of engineering education and assessment system in Korea have been reviewed and next, for those of study, the research papers and publications about the environment of college education are analyzed. Finally, an improved assessment system is suggested. It has already passed out for 6 years since execute the accreditation for engineering education in our country now, but essential point for step in accreditation for engineering education is how the evaluator can make the outcomes of studying. This is not a new terminology that is deformed according to special quality of college of engineering which prefer out-come based of study than process based of study to mean accomplishment in engineering education. The evaluation that estimate program is a skill, but an assessment method is not the meaning of individual student accomplishment also, it is the measure of validity estimation that should be estimate ability of students who complete program by proper authority. However, a new evaluation strategy that assess student outcome by person who consider the objectivity and validity, reliability should be develop for decision making of ABEEK. It is an original, private discussion for assessment strategy about the method for student learning outcomes assessment.
