  • Machine learning and deep learning (ML/DL) algorithms have been successfully applied in medical practice. However, their application in veterinary medicine is relatively limited, possibly due to a lack in the quantity and quality of relevant research. Because the potential demands for ML/DL applications in veterinary clinics are significant, it is important to note the current gaps in the literature and explore the possible directions for advancement in this field. Thus, a scoping review was conducted as a situation analysis. We developed a search strategy following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and Embase databases were used in the initial search. The identified items were screened based on predefined inclusion and exclusion criteria. Information regarding model development, quality of validation, and model performance was extracted from the included studies. The current review found 55 studies that passed the criteria. In terms of target animals, the number of studies on industrial animals was similar to that on companion animals. Quantitative scarcity of prediction studies (n = 11, including duplications) was revealed in both industrial and non-industrial animal studies compared to diagnostic studies (n = 45, including duplications). Qualitative limitations were also identified, especially regarding validation methodologies. Considering these gaps in the literature, future studies examining the prediction and validation processes, which employ a prospective and multi-center approach, are highly recommended. Veterinary practitioners should acknowledge the current limitations in this field and adopt a receptive and critical attitude towards these new technologies to avoid their abuse.

  • This study was designed to examine the influence of task appropriate processing on prospective memory(PM). The TAP was manipulated with list type within study phase and association category type among PM target words. Associated word lists used for ongoing task were consisted of semantically associated lists and orthographically associated lists. Target words for PM task were consisted of city names or words for ending with the letter of '도'. According to the TAP view, PM performance would be better in the condition of task appropriate processing rather than in the condition of task inappropriate processing. Total fifty students volunteered for two experiments for the present study. The main finding was that PM performance was influenced by the task appropriate processing with ongoing task. In other words, PM performance was facilitated when association type between ongoing list and PM target word was same. Second, ongoing task performance was also influenced by task appropriated processing. These results were discussed in task appropriated processing theory and previous studies.

  • Purpose: This prospective study aimed to examine the development of premature infants at 12 and 24 months and to explore the factors related to their development. Methods: Of the 80 premature infants who were recruited, 52 participants at 12 months and 31 participants at 24 months were included in this study. The development of the infants was examined using the Korean Bayley scale of infant development-II. Postnatal depression, husband's support, social support, mother-infant attachment, and the home environment were assessed using self-report questionnaires completed by the mothers and through the researcher's observations. Results: There was significant difference between normal and delay group at psychomotor development at 12 months depending on social support at 6 months (t=2.03, p=.049). Mother-infant attachment at 6 months (r=.71, p<.001), 12 months (r=.37, p=.043), and 24 months (r=.40, p=.026), as well as social support (r=.38, p=.034) and the home environment (r=.41, p=.022) at 24 months, were correlated to mental development at 24 months. There was a significant positive correlation between mother-infant attachment at 6 months and psychomotor development at 24 months (r=.40, p=.046). Conclusion: To reduce the risk of developmental delay and to promote healthy development in premature infants, early nursing interventions targeting mother-infant attachment, the home environment, and the mother's social support structure are needed.

  • Aim: Tanscatheter arterial embolization irrespective of with or without an anticancer agent and lipiodol has been controversial with regard to survival benefit. Therefore, we conducted a prospective study to analyze the effect of transcatheter arterial lipiodol chemoembolization (TACE) on the survival of HCC. Methods: A prospective study was conducted, and a total of 326 patients with primary liver cancer who were newly diagnosed were collected from January 2004 to January 2005 in Zhejiang Provincial People's Hospital of China. A univariate Cox's regression analysis was used to assess the survival of the HCC cases receiving TACE. Results: The duration of follow-up for the HCC patients treated with TACE ranged from 3 months to 60 months. For the overall patients, survival rate at 5 years was 42%. Both HBV Ag and HCV Ab positive patients showed significantly low survival rate at 5 years. The multivariate analysis revealed The IV TNM stage was related to an heavy increased risk of death of HCC patients, and Child C grade group showed a significant moderate increased risk. Conclusion: Our study showed TACE is associated with a better prognosis of HCC patients, and the HBV infection, TNM stage, Child-Pugh grade and number of TACE may influence the survival probability. Further TACE studies should be assess the quality of life of HCC patients, so as to provide more information for treatment of HCC.

  • Intolerance of Uncertainty is associated with numerous psychopathologies, including generalized anxiety disorders. However, several studies differ in the factor structures applicable for the Intolerance of Uncertainty Scale (IUS), and there exists a debate regarding the factorial and construct validity. Thus, in the current study, the IUS was newly translated to explore and verify the structures and factors relative to the cultural background of Korea. The study involved an exploratory factor analysis of randomly extracted data from 260 of 533 adults selected. Results determined that a prospective factor of 3 items and inhibitory factor of 5 items was appropriate. In addition, a confirmatory factor analysis and correlation analysis of the remaining 273 data revealed that a structural model comprising of the 8-items two factors model was well suited (x2=37.699, TLI=0.951, CFI=0.969, RMSEA=0.063, SRMR=0.039), and showed significant static correlation with worry, depression, and state-trait anxiety.

  • Background Breast projection is a critical element of breast reconstruction aesthetics, but little has been published regarding breast projection as the firm expander is changed to a softer implant. Quantitative data representing this loss in projection may enhance patient education and improve our management of patient expectations. Methods Female patients who were undergoing immediate tissue-expander breast reconstruction with the senior author were enrolled in this prospective study. Three-dimensional camera software was used for all patient photographs and data analysis. Projection was calculated as the distance between the chest wall and the point of maximal projection of the breast form. Values were calculated for final tissue expander expansion and at varying intervals 3, 6, and 12 months after implant placement. Results Fourteen breasts from 12 patients were included in the final analysis. Twelve of the 14 breasts had a loss of projection at three months following the implant placement or beyond. The percentage of projection lost in these 12 breasts ranged from 6.30% to 43.4%, with an average loss of projection of 21.05%. Conclusions This study is the first prospective quantitative analysis of temporal changes in breast projection after expander-implant reconstruction. By prospectively capturing projection data with three-dimensional photographic software, we reveal a loss of projection in this population by three months post-implant exchange. These findings will not only aid in managing patient expectations, but our methodology provides a foundation for future objective studies of the breast form.

  • Despite the recent increased attention to mathematics teacher education there have been lack of empirical studies on how to teach teachers. A study of mathematics instruction for prospective teachers can be conducted either by a teacher educator's critical reflection on her teaching or by observation of others' teaching practices. This paper was from the author's observation of a mathematics instruction course for future elementary teachers at the University of California at Irvine. As such this paper described in detail how the course was implemented throughout the quarter and drew implications for a teacher preparation program in Korea. As the course had a specific purpose of promoting future teachers' expertise in mathematics instruction and employed various strategies that were different from a typical university course, this paper is expected to provide teacher educators with the insight of an alternative teaching style and to provoke discussion of how to connect theory to practice for effective teacher education.

  • The paper tried to determine relationships between volunteering and hypertension risks, symptom betterment, activity difficulty occurrences, and medicine treatment among middle-aged and older adults, with a prospective cohort study. Multilevel mixed-effects generalized linear models were used for the analysis of longitudinal panel data collected over 10 years from 2008 to 2018, using 5,867 cohort samples. The results showed that those who volunteered at least 200 hours per year were 3.4 times more lower than not-volunteering in risks of hypertension, those who volunteered yearly 50~99 hours were a lot more improved than not-volunteering in the symptom betterment, those who volunteered yearly at least 200 hours were 7.7 times lower than not-volunteering in activity difficulty occurrences, and those who volunteered yearly 50~99 hours were 2.5 times lower than not-volunteering in the occurrences of medicine treatment. These indicate that volunteering among middle-aged and older adults may have health benefits against incident hypertension. Finally the thesis discusses the study limitations, future directions of studies, and the practices implications.

  • Background: Research in environmental health (EH) is of crucial strategic importance for contemporary society. It is becoming even more critical in light of the increasingly rapid pace of environmental changes, opportunities, and threats. Objectives: This study aimed to identify trends and the prospective of environmental health research using SWOT analysis. Methods: The trends in environmental health research were reviewed in previous studies and reports. Reviewed manuscripts were searched for using the keywords of 'environmental health' and 'environmental hygiene' in the KCI (Korean Journal of Citation Index), KISS (Korean Academic Information), PubMed, and Google Scholar. Results: It is essential to center the EH research agenda around key priorities focusing on technological innovation, job creation, and the increasingly prominent role of the private sector. Given the rapidly evolving global sustainability agenda, greater clarity on the ever-increasing sources of complexity and growing expectations of the public might be needed. This requires the identification of criteria to identify EH research priorities with the ultimate goal of maximizing societal benefit. Public health relevance, such as extent and severity of health impact, level of exposure, and inequalities of effects, could be included. Conclusions: Considering the recent interest in and importance of environmental health, a comprehensive approach to environmental health research should be required through the application of the latest science and technology, citizen participation, and environmental health surveillance systems.
