  • Korean medical welfare facilities for the elderly provide the conveniences to care geriatric illness such as dementia and stroke. The medical welfare facility categorizes elderly care facilities, nursing homes, and geriatrics hospitals based on the Korean welfare of the aged act. The government makes an effort to secure feed rate and finances of medical welfare facilities. However, the qualitative improvement of facilities is inadequate. The purpose of this study is to analyze the conditions and problems of existing facilities using an environmental evaluation and to discuss the improvement direction related to the daycare centers for the elderly. The method of this study is literature review and field survey. Firstly, we analyzed the previous studies to develop the tool, evaluating the environment of day care centers for the old. Secondly, the items of environmental evaluation are deduced. Thirdly, we select the facilities to conduct field survey and analyze the results of field survey. Lastly, We discussed the problems and improvement directions through the results. It is judged that this study is an useful as the basic guideline to strengthen the minimum legal standards of day care center for the elderly due to the suggestion of insufficient environmental evaluation items.

  • 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.

  • The purpose of this study is to understand middle school students' levels of cognitive conflict for the students provided quantitative demonstration and qualitative demonstration after the pre-test. 297 middle school students were selected from one school in Pusan. Action-reaction problem of mechanics and electric bulbs in parallel problem of electricity were used in the demonstration and the pre-test. Students' cognitive conflict levels were investigated using the developed items by Kwon(1999) et al. We compared cognitive conflict levels between quantitative demonstration group and qualitative demonstration group. In addition to, we compared cognitive conflict levels between students who changed their preconceptions and the students who adhered to their preconceptions. We investigated correlation between levels of faith with preconceptions and cognitive conflict levels. The study generated the following results. First, students who selected incorrect choice in pre-test showed the higher levels of cognitive conflict in quantitative demonstration group than qualitative demonstration group and students who selected correct choice in pre-test showed higher levels of cognitive conflict in qualitative demonstration group than quantitative demonstration group. Second, students who changed their preconceptions were higher levels of cognitive conflict than students who adhered their preconceptions. Third, students who selected incorrect choice in pre-test showed positive correlation between levels of faith with preconceptions and levels of cognitive conflict, and students who selected incorrect choice in pre-test showed negative correlation between levels of faith with preconceptions and levels of cognitive conflict.
