RESUMEN
BACKGROUND: The COVID-19 pandemic has precipitated an accelerated shift in education, moving from traditional learning to web-based learning. This transition introduced a notable transactional distance (TD) between the instructors and learners. Although disease control and staff and students' safety are the top priorities during a pandemic, the successful delivery of education is equally crucial. However, the ramifications of this swift transition are particularly critical in the context of dental education. Dental education is inherently practice oriented, necessitating hands-on training and manual skills development, which poses unique challenges to distance learning approaches. OBJECTIVE: This study aims to examine dental students' web-based learning satisfaction and experience of TD, investigate the predictors of web-based learning satisfaction, and explore the perceptions of students about the advantages and disadvantages of web-based learning. METHODS: This study explored the factors associated with web-based learning satisfaction using TD theory during the transition to web-based education. Psychological factors that could influence satisfaction were adapted from the health belief model. We conducted a cross-sectional web-based survey of 345 dental students from 2 institutions in South Korea who were enrolled in the spring semester of 2020. Data were collected between July 8 and September 14, 2020. Qualitative analysis was used to examine responses to open-ended questions concerning perceptions of web-based learning. RESULTS: A multivariate hierarchical linear regression model was used to analyze the effects of student characteristics, TD, and psychological factors (ie, perceived risk of infection and efficacy belief of web-based learning) on web-based learning satisfaction. The average score for web-based learning satisfaction was 3.62 (SD 0.84), just above the midpoint of the possible range (1-5). Self-regulated learning (ß=0.08; P=.046), learner-instructor interaction (ß=0.08; P=.03), and learner-content interaction (ß=0.64; P<.001) were associated with higher levels of satisfaction. Moreover, a significant association was revealed between high efficacy beliefs in web-based learning (ß=0.20; P<.001) and satisfaction. Although the learning structure (synchronous vs asynchronous) did not exhibit a significant association with satisfaction, the qualitative analysis results revealed that each structure possesses distinct strengths and weaknesses. The students in synchronous learning (79/345, 22.9%) recognized heightened autonomy in the "learning environment" (19/79, 24%); however, technical issues (28/79, 35%) and reduced concentration (15/79, 19%) were identified as downsides. Conversely, the students in asynchronous settings (266/345, 77.1%) emphasized unlimited access to learning content (74/266, 27.8%) and the flexibility of "learning in preferred time" (69/266, 25.9%). Nevertheless, challenges, such as self-management difficulties (66/266, 24.8%) and limited interactions (55/266, 20.7%), were evident. CONCLUSIONS: The findings suggest that efforts to minimize TD, facilitating self-regulated learning and interaction among students and instructors, are critical for achieving web-based learning satisfaction. Moreover, establishing a common understanding among students regarding the necessity and efficacy of web-based learning during epidemics could enhance their satisfaction.

BACKGROUND: To improve the medical professionalism of medical students, it is essential to understand the dilemmas they face in various situations. This study explored the types and distribution of dilemmas Korean medical students encounter during their clinical clerkships. It then compared these with previous dilemma frameworks and identified the types and distribution of "complexity dilemmas," wherein two dilemma themes emerge in a single clinical situation. METHODS: The researchers organized and recorded a group discussion with 106 third-year medical students who had completed their clinical clerkships. These students participated in the discussion as part of an assignment, focusing on the dilemmas they encountered during their clerkships. For data analysis and visualization, the researchers employed the MAXQDA software program and utilized the template analysis method, a qualitative research methodology. RESULTS: A total of seven dilemma themes and sixteen sub-themes were identified. The identity-related dilemma concerning student-doctors had the highest frequency. The themes "mismatch" and "Nun-chi" emerged as new additions not found in previous dilemma frameworks. The complexity dilemmas appeared in the sequence of "identity-dignity," "identity-abuse," and "identity-consent". CONCLUSIONS: To navigate the unique dilemmas present within South Korea's clinical culture, several key issues need consideration: elevating the role of student-doctors, balancing the primary emphasis of educational hospitals on delivering medical services, and understanding interpersonal strategies, such as "Nun-chi".

BACKGROUND: While closed-book examinations (CBEs) have traditionally been implemented in dental education, open-book examinations (OBEs) are being introduced for the purpose of acquiring higher levels of knowledge and promoting long-term memory. This study examines whether it is effective to use a blended assessment of CBEs and OBEs for dental students to reduce test anxiety and enhance academic performance. METHODS: Using a quasi-experimental research method, a blended assessment that combined CBEs in class and OBEs online was designed for a dental course. In 2020, when the pandemic was at its peak, student assessment was ineffective, and the 2020 cohort was omitted for our study; instead, two cohorts of predoctoral dental students (N = 178) enrolled in Restorative Dentistry in the spring semesters of 2019 and 2021 were included in the study. These students were informed about the experimental design, and they provided written consent for data collection, thereby voluntarily participating in the survey. Their self-perceived responses to open-ended survey questions on assessment methods were qualitatively analyzed. RESULTS: There was no significant difference in test anxiety between the CBEs and OBEs at the p-values of 0.001 in all items. Traditional and blended assessment showed a similar trend of lower scores in midterm exams compared to higher scores in final exams, thus discriminating against students' performances. In particular, a low-achieving group was better predicted by a blended assessment. An analysis of the students' self-perceived responses produced highly topical themes, including exam burden, learning effects, and fairness issues. CONCLUSIONS: This study confirmed the feasibility of blended assessment that can be implemented in online and in-person educational environments. Moreover, it can be used as the groundwork to develop new models of assessment in dental education.

BACKGROUND: Although research experience is important for medical students, it is difficult to develop research skills only through a formal curriculum. To develop research programs that address the authentic needs of students and align with the entirety of the medical school curriculum, a learner-centered approach may be more effective than an instructor-centered approach. This study investigates medical student perspectives on factors that help them develop research competency. METHODS: Hanyang University College of Medicine in South Korea operates the Medical Scientist Training Program (MSTP) as a supplement to its formal curriculum. Semi-structured interviews were held with 18 students (20 cases) in the program, and qualitative content analysis was performed using the software tool MAXQDA20. RESULTS: The findings are discussed in relation to three domains: learner engagement, instructional design, and program development. The students were more engaged when they perceived the program as a new experience, had prior research experience, wanted to make a good impression, and felt a sense of contribution. In terms of instructional design, they positively participated in research when their supervisors respected them, set clear tasks, provided constructive feedback, and invited them into the research community. In particular, the students highly valued relationships with their professors, and these relationships served not only as a main motivating factor in their research participation but also affected their college lives and careers. CONCLUSIONS: The longitudinal relationship between students and professors has newly emerged in the Korean context as a factor that strengthens student engagement in research and the complementary relationship between formal curriculum and MSTP was highlighted to encourage student engagement in research.

BACKGROUND: Patient-centered care (PCC) has been one of medical practice's most frequently discussed principles. However, attitudes toward PCC among dentists remain underexplored. This study focuses on examining dentists' patient-centered attitudes and investigating their predictors. METHODS: The Patient-Practitioner Orientation Scale which consists of Sharing and Caring subscales was used to assess patient-centered attitudes. The statistical analysis included 217 dentists from South Korea. Hierarchical linear regression analysis was performed to examine the predictors such as sociodemographic aspects, academic factors, work-related factors, and empathy. RESULTS: A patient-centered attitude of Caring subscale (M = 4.29, SD = 0.56) emerged, but the provider-centered attitude was higher in Sharing subscale (M = 3.40, SD = 0.48). Work year, academic track, and empathy were associated significantly with an overall caring aspect of patient-centered attitude, while the gender effect remained insignificant. Empathy had a critical and significant impact on the patient-centered attitude. CONCLUSIONS: Efforts to enhance patient-centeredness in Sharing are needed; post-graduate education and transition to a more patient-centered health system are recommended. Moreover, empathy still matters as it was found to be a significant predictor of patient-centered attitudes. The findings of this study support the need for efforts to enhance patient-centered attitudes among dentists, which will help generate discussion on improving the curriculum of post-graduate education and health system reform.

During the COVID-19 pandemic, healthcare professionals have often faced moral challenges, which required them to choose between endorsing self- or other-sacrifice for the greater good. Drawing on the altruistic rationalization hypothesis and trait-activation theory, this study investigates (a) whether healthcare students' endorsement of utilitarian solutions to sacrificial moral dilemmas varies when they are confronted with the minority group, majority group, or third-person perspective on the given dilemma and (b) whether individual differences in utilitarian thinking, as measured by the Oxford Utilitarianism Scale (both instrumental harm and impartial beneficence), predict endorsement of utilitarian solutions to moral dilemmas. The study population was divided into a group of healthcare students and a group of non-healthcare students. It was found that the members of both groups expressed a stronger pro-utilitarian position when making moral dilemma judgments from a majority perspective than from the two other perspectives. However, a difference was observed with healthcare students being more reluctant to endorse the utilitarian action than their non-healthcare counterparts in the self-in-majority context. The instrumental harm component was a significant predictor of utilitarian judgments in the healthcare group, but impartial beneficence significantly predicted utilitarian judgments in the non-healthcare group in the self-in-majority context.

RESUMEN
This study aimed to measure real-time temperature changes in gold-restored teeth compared with intact teeth during the intake of hot and cold drinks. Sixteen molars, including eight natural intact teeth and eight restored teeth with gold inlays, were selected from the participants. Custom-made thermocouple sensors were attached to the coronal third of the buccal surface of teeth. Participants consecutively consumed hot and cold drinks according to a standardized regimen. Resting, maximum, and minimum temperatures; time to reach peak temperatures; and heating and cooling velocities were obtained. Statistical analysis was performed using independent two-sample t-test. Teeth with gold restorations showed a significantly higher maximum temperature (44.7 °C [SD 2.9]) than did natural teeth (40.5 °C [SD 1.2]) during hot water drinking and showed a lower minimum temperature (25.0 °C [SD 4.9]) than did natural teeth (31.5 °C [SD 3.1]) during cold water drinking. The heating and cooling rates for the teeth with gold restorations were two and three times higher than those of the natural teeth. Gold-restored teeth showed greater temperature change than intact teeth in terms of magnitude and velocity in response to temperature changes induced by hot and cold drinks.

BACKGROUND: The COVID-19 pandemic has highlighted prosocial behavior as a professional healthcare core competency. Although medical students are expected to work in the best interests of their patients, in the pandemic context, there is a greater need for ethical attention to be paid to the way medical students deal with moral dilemmas that may conflict with their obligations. METHODS: This study was conducted in the spring semester of 2019 on 271 students majoring in health professions: medicine, dentistry, and veterinary medicine. All participants provided informed consent and completed measures that assessed utilitarian moral views, cognitive reflections, cognitive reappraisal, and moral judgment. RESULTS: The healthcare-affiliated students who scored higher on the instrumental harm subscale in the measurement of utilitarian moral views were more likely to endorse not only other-sacrificial actions but also self-sacrificial ones for the greater good in moral dilemma scenarios. In particular, those engaged in deliberative processes tended to make more self-sacrificial judgments. The mediation analysis also revealed that the effect of deliberative processes on self-sacrificial judgments was mediated by cognitive reappraisal. CONCLUSIONS: These findings suggested that cognitive reappraisal through deliberative processes is involved when the students with utilitarian inclination make prosocial decisions, that it is necessary to consider both moral views and emotional regulation when admitting candidates, and that moral education programs are needed in the healthcare field.

BACKGROUND: This study aimed to examine the satisfaction, educational linkage, and self-perceived competence of dental students enrolled in either 4 + 4 dental program, comprising an undergraduate degree and Doctor of Dental Surgery degree (DDS), or 3 + 4 program, which is a BS/DDS combined degree program, in the Korean dental education system. MATERIALS AND METHODS: The survey questionnaire using a 5-point Likert scale was developed and validated by four dental education experts, consisting of satisfaction with undergraduate courses, the interconnection of undergraduate courses with the DDS curriculum, and self-assessed core competency for dental graduates. A total of 252 students provided informed consent and voluntarily responded to the survey, among whom 109 students were in the 3 + 4 system and 143 were in the 4 + 4 system. Cronbach's correlation analysis and independent t-test were conducted for each evaluation item. RESULTS: Students' overall satisfaction level with the undergraduate education was higher in the 4 + 4 system than in the 3 + 4 system (P = 0.003). Students enrolled in the 4 + 4 system recognized that natural sciences are more connected to the graduate-level DDS program (P < 0.001), while the 3 + 4 students recognized that studies in medicine are closely interconnected to the DDS program (P = 0.001). There was almost no statistically significant difference in the students' perception of competency between the two education systems. DISCUSSION: Even though this study analyzed the case of a single university operating both 3 + 4 and 4 + 4 systems, it can be used as the groundwork for developing new opportunities and models of dental education system.

BACKGROUND: COVID-19 caused significant confusion around the world, and dental education was no exception. Therefore, in line with the demands of the times, this study sought to determine the applicability of online active learning to dental education. METHODS: This study was conducted in the second semester of 2020 at a school of dentistry in a selective university in Korea. A total of 114 dental students were recruited. Participants were assigned to four different groups (lecture and discussion [LD], lecture and discussion with instructor's worksheet [LW], self-study and discussion [SSD], and self-study and discussion with instructor's worksheet [SW]) using the random breakout room function in the Zoom video conference application. Their final test scores were then analyzed using analysis of variance and the online active learning results were compared with the offline learning results. RESULTS: The scores were highest for the transfer type items in the SSD group, followed by the SW group and the two lecture groups, which had no significant differences. These scores and pattern differences between the groups were similar for all items. The results suggested that studying by oneself rather than simply listening to lectures enhanced the effects of the discussions and led to higher learning outcomes. In addition, the effect of the instructor's intervention in the middle of the discussion varied depending on the pre-learning activities of discussion. As with previous offline experiments, self-study followed by group discussion had higher learning outcomes for both the verbatim and transfer type items. CONCLUSIONS: In agreement with the Interactive, Constructive, Active, and Passive (ICAP) framework and other active learning theories, the findings clearly indicated that online active learning was applicable to dental students, and when self-study precedes discussion, the learning is richer and the learning outcomes are better.

BACKGROUND: Enhancing medical students' practice of patient-centered care is a goal of medical schools. In addition to exploring the demographic and academic factors of the students, it is necessary to identify other attitudes and perceptions that may influence the student's patient-centered attitude and inclination toward communication skill learning. This study aimed to assess patient-centered attitudes among dental students in Korea and identify the association between the students' characteristics and empathy, communication skill learning attitude, and patient-centered attitude. METHODS: Data were collected via a cross-sectional online survey, and 312 dental students were included in the analyses. The study participants completed the Patient-Practitioner Orientation Scale (PPOS), the Interpersonal Reactivity Index (IRI), and the Communication Skills Attitude Scale (CSAS). Analyses were performed using independent samples' t-tests, hierarchical multi-variable regression, and ANOVA with a post-hoc Tukey test. RESULTS: The students tend to be moderately patient-oriented toward the sharing subscale of PPOS score (M = 3.78, standard deviation [SD] = 0.54) and slightly more patient-centered toward the caring subscale of PPOS score (M = 4.41, SD = 0.52) of patient-centered attitudes. Being a female and a shorter academic period in dentistry were associated with attitudes toward patient-centered care. Empathy and positive attitude toward learning communication skills were also related to a patient-centered attitude, and among aspects of empathy, "empathic concern" had the greatest significant impact on patient-centered attitude. CONCLUSIONS: Gender, academic period, empathy, and attitudes on learning communication skills were important influencing factors of patient-centered attitudes. Patient-centered attitude can and must be taught. Education programs should focus on enhancing empathy, emphasizing positive attitudes on learning communication skills, and conducting follow-up educational sessions to prevent students from becoming less patient-centered with an increase in duration of their academic period.

BACKGROUND: Writing is a useful learning activity that promotes higher-order thinking, but there are limited studies that prove its effectiveness. In previous research, researchers tested the effect of summary writing on students' comprehension and found no significant difference from that of re-studying texts. The purpose of this study, therefore, is to expand previous findings and investigate the effect of two types of writing tasks on medical students' academic performance, specifically in the transfer of knowledge. METHODS: An experiment was conducted with 139 medical students from Seoul National University College of Medicine. They were randomly assigned to three study conditions: self-study (SS), expository writing (EW), and argumentative writing (AW) group. Each group studied the given material by the method they were assigned, and they were tested on their comprehension and transfer of knowledge using rote-memory type items and transfer type items respectively. RESULTS: The results showed that the two writing groups displayed better performance than the SS group in transfer type items, while there was no difference in scores between the EW and AW group. However, the three groups showed no significant difference in their scores for rote-memory type items. Also, there was a positive correlation between the writing scores and transfer type item scores in the AW group. CONCLUSIONS: This study provides empirical evidence for writing to be adopted in medical education for greater educational benefits. Our findings indicate that writing can enhance learning and higher-order thinking, which are critical for medical students.

Facial expressions are well known to change with age, but the quantitative properties of facial aging remain unclear. In the present study, we investigated the differences in the intensity of facial expressions between older (n = 56) and younger adults (n = 113). In laboratory experiments, the posed facial expressions of the participants were obtained based on six basic emotions and neutral facial expression stimuli, and the intensities of their faces were analyzed using a computer vision tool, OpenFace software. Our results showed that the older adults expressed strong expressions for some negative emotions and neutral faces. Furthermore, when making facial expressions, older adults used more face muscles than younger adults across the emotions. These results may help to understand the characteristics of facial expressions in aging and can provide empirical evidence for other fields regarding facial recognition.

BACKGROUND: The ICAP framework based on cognitive science posits four modes of cognitive engagement: Interactive, Constructive, Active, and Passive. Focusing on the wide applicability of discussion as interactive engagement in medical education, we investigated the effect of discussion when it was preceded by self-study and further investigated the effect of generating questions before discussions. METHODS: This study was conducted in the second semester of 2018 and was participated in by 129 students majoring in health professions, including medicine, dentistry, veterinary medicine, and nursing. The students were assigned to four different trial groups and were asked to fill out a Subjective Mental Effort Questionnaire after completing each session. Their performance in posttest scores was analyzed using Bonferroni test, and mental effort was analyzed using mediation analysis. RESULTS: These results indicated that the self-study and question group had the highest performance and that the lecture and summary group had the lowest performance when comparing the total score. Using the analysis of mental effort, it was confirmed that the relationship between different study conditions and post-test performance was mediated by mental effort during test. CONCLUSIONS: Our findings support the ICAP framework and provide practical implications for medical education, representing the fact that students learn more when they are involved in active learning activities, such as self-study and question generation, prior to discussions.

PURPOSE: To investigate the influence of dentifrices with and without abrasives on the wear and surface topography of human dentin following simulated toothbrushing in vitro. METHODS: 24 dentin specimens were prepared and randomly allocated to a liquid dentifrice (Garglin Gum-Guard), conventional dentifrice (333 Clinic Total Care), and control (distilled water) groups. Specimens were subjected to simulated toothbrushing of 50,000 repeated strokes under a 150 g-load. The dentin surface was profiled in each specimen using a profilometer before and after toothbrushing. The mean surface roughness (Ra) of the specimens was calculated and compared by one-way ANOVA and Tukey's post-hoc test (α = 0.05). The dentin surfaces were further examined by scanning electron microscopy (SEM). RESULTS: The Ra values were similar between the liquid dentifrice and control groups (P > 0.05), and was significantly higher in the conventional dentifrice group (P < 0.001). On SEM examination, patent dentin tubules were observed in the conventional dentifrice and liquid dentifrice groups, but were not observed in the control group.

OBJECTIVE: The objective of this study was to explore the process of becoming an independent dentist, extending beyond the entry-level period. MATERIALS AND METHODS: Fifteen general dental practitioners were interviewed. The recorded interviews were transcribed verbatim, and utilizing Colaizzi's descriptive phenomenological method, we sought to exclude subjectivity and derive meanings and themes from participants' experiences concerning the process of becoming independent dentists. RESULTS: The study identified 3 phases in the process of developing as an independent dentist: (1) the foundation phase, involving dental training as a student under faculty supervision; (2) the extension phase, expanding experience as an entry-level dentist; (3) the equilibrium phase, characterized by providing stable dental care based on diverse experience and professionalism. CONCLUSION: Becoming an independent dentist entails more than unsupervised treatment provision; it involves developing the professionalism necessary for delivering quality dental care through deliberate practice and reflection. CLINICAL RELEVANCE: The study outlines the stages of transitioning to an independent dentist, spanning foundational training, entry-level experience, and achieving stable care provision. Emphasizing the importance of professionalism and reflection, it provides a valuable framework for enhancing dental education and on-going professional development, fostering both technical proficiency and a commitment to quality patient care.
RESUMEN
The pandemic has affected the lives of people all over the world. The effects of the pandemic on laboratory animal facilities and their operations through this unusual global event are poorly understood. Here, we have applied a methodological framework of qualitative approach including semi-structured interviews to investigate laboratory animal operations in Korea and how it has shaped the on-going management and laboratory operations of such facilities. A total of fifty-two individuals, including members and administrators of the Institutional Animal Care and Use Committee (IACUC), researchers, and animal facility managers and staff, were surveyed through purposeful sampling. Survey questions explored how the pandemic impacted the IACUC and the functioning of animal facilities, and what steps to take in preparation of a future pandemic-like crisis. Our survey found evidence of an increase in animal experiments in Korea during the pandemic that correlated with increases in research funding during that period, such as for vaccine development. Also, operational challenges due to pandemic-related health issues in personnel were resolved through overtime, rather than by reducing facility operations. Moreover, a refinement of post-approval monitoring (PAM) practices was also discussed by respondents. Taken together, our study offers insights into animal facility operations during the pandemic and outlines recommendations for safeguarding operations in such future scenarios.

PURPOSE: Students report various motives for attending university (MAU) grouped under five categories, namely, personal-intellectual development (PER), humanitarian (HUM), careerist-materialist (CAR), expectation-driven (EXP), and uncertain motives. Although the literature demonstrates that these motives exert an influence on learning and achievement, relatively less attention is given to this issue in the context of dental students. This study aimed to examine the relationship among the mindsets, MAU, academic engagement (AE), and DAL of dental students and to test the mediating effect of AE on the relationship between MAU and deep approach to learning (DAL). METHODS: The study recruited 226 dental students at various levels of the curriculum, who responded to four questionnaires for measuring MAU, DAL, mindsets, and AE. The study employed structural equation modeling to analyze the mediation effects of AE on the relationship between MAU and DAL and to determine the influence of mindsets on MAU. RESULTS: This model reveals the significant relationships of a growth mindset with CAR, PER, and HUM. Moreover, the study finds that a fixed mindset was associated with CAR, EXP, and uncertain motives. Furthermore, AE only fully mediated the significant positive relationship between PER and DAL, whereas CAR negatively predicted DAL without a mediator. CONCLUSIONS: These findings suggest that administering the inventories in a dental school setting can facilitate a more comprehensive understanding of students' mindsets toward learning and effective processes related to learning. This understanding can inform instructors' pedagogical practices, enabling them to provide more effective guidance to students navigating the complexities of academic coursework.

BACKGROUND: Black children are significantly overrepresented in many phases of the U.S. child welfare system. OBJECTIVE: The purpose of this study is to investigate racial disproportionality and disparities in the adoption process and factors that predict the length of time to adoption. PARTICIPANTS AND SETTING: This study utilized administrative data from the 2014 year of the Adoption and Foster Care Analysis and Reporting System (AFCARS) collected in 50 States, the District of Columbia, and Puerto Rico. METHODS: The disproportionality metric (DM) and disparity index (DI) were constructed for Black and White children, and event history analyses were conducted to calculate the probability of adoption while considering the time to adoption finalization. RESULTS: DM indicated that Black children (0.81) were underrepresented in adoption, and DI indicated that the likelihood of adoption for Black children (0.73) was one third lower than that for White children. The event history analyses revealed that White children were 1.27 times more likely to be adopted than Black children. White children had considerably fewer days from termination of parental rights to adoption finalization with a median time of 273.5 days compared to 328 days for Black children. Factors that extended adoption time included child intellectual, physical, and emotional/behavioral disabilities, visual and hearing impairments, parental alcohol abuse and disability, and child maltreatment histories, while parental drug abuse and longer stays in out-of-home care shortened the adoption process. We also found a significant interaction effect of race and neglect on adoption. Neglected Black children had a longer time to adoption than neglected White children. CONCLUSIONS: More dedicated outreach programs and resources must be developed to ensure the effectiveness of adoption services and cultural continuity for Black children.

BACKGROUND: The Institutional Animal Care and Use Committee (IACUC) became compulsory in 2008 by the Animal Protection Act in Korea. Seoul National University (SNU), which conducts 5% of Korea's total animal protocol reviews and uses 10% of national laboratory animal usage, has been influential in the review of animal protocols and management of animal facilities. This study was undertaken to suggest the operational improvement of the IACUC. It focused on the case of SNU. RESULTS: The methodological framework consists of a qualitative approach. In particular, this study is focused on the grounded theory approach and sixty people were surveyed through purposeful sampling. Through this study, we found that various practical educations are necessary such as: (1) education for researchers on how to write a protocol, (2) standardization of screening criteria for various animal experiments by presenting various cases, (3) training on a detailed understanding of relevant laws and policies. In particular, an integrated management system, making it possible to share information among the related committees, would be essential for smoother operation of the IACUC. CONCLUSIONS: If various levels of education and the integrated management system are established, it will be possible to enhance the excellence of researchers and to better manage the operation of the IACUC.
