Due to the development of advanced technology, a lot of digital radiographic equipment has been developed, which is very helpful for accurate diagnosis and treatment, and it is very important to train personnel who have acquired professional knowledge in order to use it safely and effectively. Students are exposed to the risk of radiation exposure in radiography training using diagnostic X-ray equipment, and some educational institutions do not use X-ray equipment due to management difficulties in accordance with the Nuclear Safety Act. As a solution to this, this study developed a medical radiation simulator for education that does not generate radiation by using a vision sensor and self-developed software. Through this, educational institutions can reduce the burden of administrative implementation according to the law, and students can obtain a high level of educational effects in a healthy practice environment without radiation exposure.

Purposes: Patient experience is a tool to evaluate the process and results of medical services provided by medical institutions from the patient's point of view. Patient satisfaction surveys are a meaningful and essential source of information for improving quality in healthcare organizations. This study aims to provide basic data for improving the quality of medical service that patients can feel by analyzing the recommendation intention and satisfaction of inpatients in specialty hospitals. Methodology: The subjects of this study were 879 inpatients in 28 specialty hospitals in 14 designated fields. We conducted a telephone survey with a structured questionnaire on the satisfaction and recommendation intention for specialty hospitals. Findings: In inpatients, hospital satisfaction was higher in nursing care services and hospital satisfaction was low in physicians care services. The overall patient satisfaction score was 91.4(SD=11.9) out of 100, and the intention of recommendation was 92.0(SD=14.1) out of 100. The factors affecting patient experience were designated fields, sex, age, residential area, monthly household income, and perceived health status. Practical Implications: This study confirmed the high level of patient satisfaction and recommendation intention among inpatients of specialty hospitals. Patient satisfaction can be of great value to healthcare providers in recognizing and improving the quality of care, as well as predicting patients' willingness to revisit medical institutions. This study can be used to improve the quality of hospital care services in specialty hospitals rather than general and tertiary general hospitals.

Purpose : This study aimed to investigate the characteristics and risk factors associated with pressure injuries related to medical devices among patients admitted to the intensive care unit (ICU). Method : A retrospective study analyzed data from 462 ICU patients. Statistical analyses, including independent t-tests, Fisher's exact tests, and logistic regression were performed to analyze the data. Results : Among the 154 subjects, there were a total of 198 medical device-related pressure injuries (MDRPI). Stage 2 and deep tissue pressure injuries were the most frequent. MDRPI occurred most frequently on the face, with nasogastric tubes being its leading cause, followed by endotracheal tubes. The risk factors for MDRPI included male sex (odds ratio [OR]=1.78, 95% confidence interval [CI]=1.12-2.83), department at the time of ICU admission (OR=4.29, 95% CI=2.01-9.15), post-surgery ICU admission (OR=0.43, 95% CI=0.25-0.73), application of extracorporeal membrane oxygenation machines (OR=2.72, 95% CI=1.06-6.95), number of medical devices (OR=1.16, 95% CI=1.05-1.30), inotropic drug administration (OR=2.33, 95% CI=1.19-4.60), and sedative use (OR=2.53, 95% CI=1.17-5.45). Conclusion : These results enable the determination of the characteristics and risk factors associated with MDRPI. It is crucial to acknowledge the risk factors for MDRPI in ICU patients and establish a prevention strategy.

This study investigated the effect of oral health on health-related quality of life in cancer patients and cancer survivors using data from the 7th Korea National Health and Nutrition Examination survey. Data analysis was a complex sample analysis using SPSS/WIN 26.0. As a result of conducting complex sample logistic regression analysis to investigate factors affecting the quality of life of cancer patients and cancer survivors, the average quality of life was 1.18 points for cancer patients and 1.16 points for cancer survivors. The quality of life of cancer patients was significantly lowerer when they had discomfort chewing and speech difficulties, and needed dentures. Cancer suvivors was significantly lowerer when they had speech difficulties. Therefore, it is necessary to recognize the importance of oral care for cancer patients and cancer survivors, and to develop and utilize oral health care programs so that continuous and professional access to oral health care is necessary.

This study was investigate the relationship between vaccination and clinical practice during the COVID-19 period, when clinical practice education for public health students is shifting to a non-face-to-face direction. Students' clinical practice experience after graduation is an important part of their professional careers. The result that students who wanted to work in health care had a higher level of face-to-face clinical practice than students who did not (OR: 3.421, 95%CI: 1.333-8.775). Face to face clinical practice was higher among vaccination students (OR: 2.522, 95%CI: 1.017-6.254). In the non-face-to-face clinical practice conducted at the COVID-19 of environment students were found to be low in satisfaction with the overall clinical practice due to concerns about contracting infectious diseases. Additionally, I felt anxious about working in the field after getting a job. Accordingly, we will be able to enhance the professional role of students by actively supporting vaccinations that can relieve anxiety about infectious diseases and conducting face-to-face clinical practice.

We surveyed the lecture types and campus lifes which college students preferred during COVID-19 Pandemic situation. Students who attend colleges in Gwangju city, Jeonnam and Jeonbuk province, answer a questionnaire. The principal result of the survey showed that all grades preferred un-contact lecture but nevertheless also preferred the compound method of contact and un-contact lecture(p=0.923). In educational satisfaction degree by lecture type, the degree of satisfaction for contact lecture ranked highest at 2.82(p=0.000). But the survey showed the degree was not a variable which had a significant effect on the improvement of scholastic performance(p=0.325). The questionnaire analysis shows that students demand un-contact lecture high because of infection risk, but they wish the un-contact lecture which can solve problems in real time rather than the recorded lecture. As a result of this study, instructor is highly required to prepare un-contact teaching plans which reflect the demands of students.

In order to prevent aspiration pneumonia, oral hygiene care is important; thus proper tips for oral hygiene care should be distributed among hospitals and care facilities for elderly. Malpractice of oral hygiene itself may cause aspiration pneumonia. For efficient and effective oral hygiene care, engagement of professionals such as dentists or dental hygienists is essential. At the point where necessity of systemized dental $professionals^{\circ}{\phi}$ involvement at care facilities for elderly is being emerged, it is important to determine less risky approaches for oral health care tailored to elderly. Among many approaches, oral health care practice without usage of water is considered safe, reducing risk of possibility of aspiration. Since this practice is quite easy to implement, many dental professionals may utilize it when practiced at care facilities for elderly.

This paper presents the proposed a classifier of liver cirrhotic step using MR(magnetic resonance) imaging and hierarchical neural network. The data sets for classification of each stage, which were normal, 1type, 2type and 3type, were analysis in the number of data was 231. We extracted liver region and nodule region from T1-weight MR liver image. Then objective interpretation classifier of liver cirrhotic steps. Liver cirrhosis classifier implemented using hierarchical neural network which gray-level analysis and texture feature descriptors to distinguish normal liver and 3 types of liver cirrhosis. Then proposed Neural network classifier learned through error back-propagation algorithm. A classifying result shows that recognition rate of normal is $100\%$, 1type is $82.8\%$, 2type is $87.1\%$, 3type is $84.2\%$. The recognition ratio very high, when compared between the result of obtained quantified data to that of doctors decision data and neural network classifier value. If enough data is offered and other parameter is considered this paper according to we expected that neural network as well as human experts and could be useful as clinical decision support tool for liver cirrhosis patients.
