The role of artificial medical intelligence through medical big data has been focused on data-based medical device business and medical service technology development in the field of diagnostic examination of the patient's current condition, clinical decision support, and patient monitoring and management. Recently, with the 4th Industrial Revolution, the medical field changed the medical treatment paradigm from the method of treatment based on the knowledge and experience of doctors in the past to the form of receiving the help of high-precision medical intelligence based on medical data. In addition, due to the spread of non-face-to-face treatment due to the COVID-19 pandemic, it is expected that the era of telemedicine, in which patients will be treated by doctors at home rather than hospitals, will soon come. It can be said that artificial medical intelligence plays a big role at the center of this paradigm shift in prevention-centered treatment rather than treatment. Based on big data, this paper analyzes the current status of artificial intelligence technology for chronic disease patients, market trends, and domestic and foreign company trends to predict the expected effect and future development direction of artificial intelligence technology for chronic disease patients. In addition, it is intended to present the necessity of developing digital therapeutics that can provide various medical services to chronically ill patients and serve as medical support to clinicians.

This study intended to identify dental hygienists' knowledge and extent of awareness and performance of patient's personal information protection. In addition, this research was conducted to contribute to medical centers' preparation of measures to strengthen the personal information protection by identifying the factors affecting dental hygienists' extent of performance related to the patient's personal information protection. After explaining the purpose and meaning of the research to the survey participants and gaining their consent, a self-administered survey was conducted from November 7, 2014 to June 30, 2015. The data on 210 dental hygienists in Busan city and Gyeongsangnam-do province was used for analysis. As a result, in dental hygienists with more than 10 years experience, the extent of the performance was significantly high (p<.05). In positions higher than a senior manager, the extent of knowledge was high (p<.01) and the extent of performance was significantly high (p<.05). In hospitals with more than 10 to 20 workers, the extent of awareness was significantly high (p<.05). Regarding the correlation of knowledge and the extent of awareness and performance, a high level of knowledge showed a positive correlation of the extent of awareness and performance (p<.01). As a result of a survey regarding what effects dental hygienists' knowledge and extent of awareness of patient's personal information protection have on dental hygienists' extent of performance, it was found that knowledge (.231) and the extent of awareness (.212) are factors affecting the extent of performance. Therefore, to increase the extent of dental hygienists' performance of patient's personal information protection, there is a need to improve the knowledge of patient's personal information protection and change its awareness. To change the awareness of patient's personal information protection, there is a serious need to carry out education targeting dental hygienists.

Based on data from the Korean Academy for Dental Administration, which has been conducting the Dental Quality Improvement (QI) Contest since 2010, we aimed to provide basic data for the development of dental quality improvement indicators by analyzing the trends of dental quality improvement activities. A total of 54 articles in the dental QI contest from 2015 to 2021 were used to search for frequently used words and to classify the quality of dental care. The criteria for the quality dimension of dental care were first classified into structure, process, and outcome, and secondary classification was performed into patient safety, timeliness, patient-centeredness, equity, efficiency, effectiveness, and accessibility. The frequently used key terms were satisfaction (five times), efficiency (four times), system (three times), and implant (three times). The activities for process evaluation were high at 62.26%, structural evaluation activities at 35.85%, and outcome evaluation activities at 1.89%. According to the components of dental care quality improvement, the activity performed under efficiency was the highest (33.96%), followed by patient-centeredness (18.87%), effectiveness (16.98%), patient safety (15.09%), accessibility (5.66%), timeliness (1.89%), and the equity (1.89%). QI activities in dental hospitals were mainly activities on improvement in structure and process, as well as activities on efficiency, patient-centeredness, effectiveness, and patient safety.

To realize the U-healthcare system, the mobile patient monitoring system is of the essence. In this monitoring system, a patient's real-time data on biometrics and location must be transferred to predeterminate destination server ceaselessly. As the number of mobile patients increases steadily or mobile patients are moving into some specific area, the load balancing solution to real-time data congestion problem is needed. In this paper, we propose a new mobile patient monitoring system with Torus topology where three layers are connected hierarchically and the intermediate layer takes charge of priority-based load balancing. For the formalized design and verification of proposed system, we describe the overall structure with connectivity among its components and implement major components in pseudo-code by adopting a system specification-based approach. This approach makes the design and verification of our mobile patient monitoring system more flexible and accurate.

Purpose: Low dose of PET/CT is important because of Patient's X-ray exposure. The aim of this study was to evaluate the effectiveness of low-dose PET/ CT image through the CTAC and QAC of patient study and phantom study. Materials and Methods: We used the discovery 710 PET/CT (GE). We used the NEMA IEC body phantom for evaluating the PET data corrected by ultra-low dose CT attenuation correction method and NU2-94 phantom for uniformity. After injection of 70.78 MBq and 22.2 MBq of 18 F-FDG were done to each of phantom, PET/CT scans were obtained. PET data were reconstructed by using of CTAC of which dose was for the diagnosis CT and Q. AC of which was only for attenuation correction. Quantitative analysis was performed by use of horizontal profile and vertical profile. Reference data which were corrected by CTAC were compared to PET data which was corrected by the ultra-low dose. The relative error was assessed. Patients with over weighted and normal weight also underwent a PET/CT scans according to low dose protocol and standard dose protocol. Relative error and signal to noise ratio of SUV were analyzed. Results: In the results of phantom test, phantom PET data were corrected by CTAC and Q.AC and they were compared each other. The relative error of Q.AC profile was been calculated, and it was shown in graph. In patient studies, PET data for overweight patient and normal weight patient were reconstructed by CTAC and Q.AC under routine dose and ultra-low dose. When routine dose was used, the relative error was small. When high dose was used, the result of overweight patient was effectively corrected by Q.AC. Conclusion: In phantom study, CTAC method with 80 kVp and 10 mA was resulted in bead hardening artifact. PET data corrected by ultra- low dose CTAC was not quantified, but those by the same dose were quantified properly. In patients' cases, PET data of over weighted patient could be quantified by Q.AC method. Its relative difference was not significant. Q.AC method was proper attenuation correction method when ultra-low dose was used. As a result, it is expected that Q.AC is a good method in order to reduce patient's exposure dose.

Patient satisfaction is an important factor in evaluating the quality of care. Patient satisfaction may be used to evaluate provider services and facilities, and used to predict the patient returns to a facility. The patients d whether the patient returns to a facility or whether the patient recommends the facility to other people may be affected by a variety of factors of patient satisfaction. Low satisfaction may result in poor compliance with the potential of waste of resources and suboptimal clinical outcome. This study is to identify factors of patient satisfaction that will affect patients decision whether the patient returns or not. A self-administered questionnaire survey was conducted in Seoul, Chung-Joo and Bu-Cheon cities, Survey data was obtained from 743 patients who visited the physical therapy practice at university hospitals, general hospitals and clinics. Response rate was 94.4%. The instrument developed by Goldstein et al. (2000) was used and translated into Korean. Several items were added to the instrument. Patient's opinions of service in each domain measured using 5-point Likert-type scales that ranged from strongly disagree to strongly agree. A multiple-regression analytic approach was used to predict overall satisfaction of physical therapy. Age, kindness, scheduling, convenience of parking, privacy, and waiting time predicted the overall satisfaction of physical therapy. The older patients had higher level of satisfaction with physical therapy compared with the younger patients. Patient satisfaction were more affected by access (scheduling and waiting time), administrative technical management (convenience of parking), and interpersonal management (kindness of physical therapists and other staffs) than clinical technical management (physical therapists' skills).

Since the introduction of Western concept of nursing to Korea in late 1880s, Korean nursing practice has evolved into Korean culture. The purpose of this study was to explore and identify similarities and differences in hospital nursing practice between Korea and the United States using the grounded theory method. The data were gathered from 15 Korean nurses working in U.S. hospitals using semi-structured, in-depth interview method. Major similarities in nursing practice between Korea and U.S. existed in the 7 domains that Benner indicated in 1984. The nursing administration system was also similar in both countries. On the other hand, differences existed in how nurses execute these domains of nursing practice. These are the roles of nurses. nurse aides and family members. and the interpersonal relationships, and problem presentation and problem-solving strategies. American family members rarely participated in the patient's bedside nursing care, while Korean family members actively participated. American nurse aide participated in direct patient care, while Korean nurse aides did not. Also Korean nurses were participated more in administering and managiang the patient's diagnostic and treatment modalities, while American nurses foucused on the needs and demands of the patient. In terms of interpersonal relationships, American patients were more self-centered and demanding than Korean. American nurses focused more on the right of individuals while Korean nurses were more oriented to harmony with the coworkers. With inferiors and superiors, American members were more egalitarian, while Koreans tended to be hierachical. In ways of suggesting problems, American nurses tended to pick out the problems more frequently than Korean nurses did.. As to ways to solve the problems, American nurses relied heavily on explicit verbal explanations, while Korean nurses relied more on bodily action and behaviors. The results of this comparative study contribute to nursing by adding knowledge on the theory of culture care by describing the similarities and differences in nursing practice between Korea and the United States.

This study was conducted to identify factors affecting patient safety management (PSM) of nursing student's who have experienced clinical practice. The study subjects were 232 nursing students in five universities in five cities. Data were collected between June 17 and July 30, 2019 using by completing structured self report questionnaires. Data were analyzed using T-test, ANOV A, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 22.0. In correlation ana lysis, significant positive correlations were found between PSM practice, PSM importance awareness (r= .42, p<.001), PSM knowledge(r= .29, p<.001), and PSM attitude(r= .35, p<.001). In multiple regressi on analysis, PSM importance awareness(β=.19, p<.001) was factor predicting PSM practice of nursing students, which explained 36.2% of the variance in the model. Thus, we emphasize that continuing PSM education at the university is required to improve PSM competency.
