Background: The purpose of this study is to analyze the current status and factors of elderly patients' hospitalization for hip replacement, knee replacement, and general spine surgery. Methods: National health insurance data in 2018 was provided by the National Health Insurance Service. We used multiple regression to analyze factors associated with the medical utilization of hip replacement, knee replacement, and general spine surgery in elderly patients over 65 years old. The dependent variables are the length of stay and total health expenditure. The independent variables are the demographic-social factors (sex, age, region, insurance type, income level) and surgery-related factors (institution type, location of the hospital, surgery classification). Results: The most common factor affecting surgery was the location of medical institutions. Compared with the medical institutions located in metropolitan, the length of stay in rural medical institutions was higher and total health expenditure was lower. The lower quartile of income, the higher the length of stay and total health expenditure. In addition, the variables of age, type of health insurance, and type of medical institution were statistically significant. Conclusion: In this study, we confirmed the effect of sociodemographic factors and medical institution factors on the Healthcare Utilization of spinal and joint surgery.

Objectives : The aim is to examine what a selective factor of dental institution in the elderly is, which can be used as a strategy for vitalizing hospital management, and which difference there is in selection of dental institution according to health-promotion lifestyle. Methods : Questionnaire survey of individual interview was carried out targeting 177 old people in over 65 years old of Jeonju, Iksan, and Gunsan in Jeollabuk-do Province by convenience sampling from August 16, 2010 to August 27. The analysis was performed by using SPSS WIN 12.0 program. Results : 1. The average mark of health-promotion lifestyle in the elderly was 2.69 points. The health responsibility was the highest with 2.91 points. 2. The mark of health-promotion lifestyle was higher in the higher educational level of the elderly(p<0.01), when monthly income is more than 2 million won(p<0.01), and in the better subjective awareness of oral condition(p<0.01). 3. The group with high mark of health-promotion lifestyle regarded reliability(p<0.001), economic efficiency(p<0.01), and facilities & cleanliness(p<0.01) as important factors when selecting dental institution. Conclusions : The development and expansion in health-promotion program targeting the elderly are seen to be necessary that reflect difference by sphere in health-promotion lifestyle. There will be necessity for pursuing even a strategy for the elderly in the group who have relatively low characteristic in the practice level of health-promotion lifestyle. Also, given understanding characteristics on the elderly and focusing on management proper for the needs of medical consumers, the successful medical management is thought to be likely possible.

The article reflects short-term perspectives on the use of information and communication technologies in the training of teachers for higher education. Education is characterized by conservatism, so aspects of systematic development of the industry are relevant to this cluster of social activity. Therefore, forecasting the introduction of innovative elements of ICT training is in demand for the educational environment. Forecasting educational trends are most relevant exactly in the issues of training future teachers of higher education because these specialists are actually the first to implement the acquired professional skills in pedagogical activities. The article aims to consider the existing potential of ICT-based learning, its implementation in the coming years, and promising innovative educational elements that may become relevant for the educational space in the future. The tasks of scientific exploration are to show the optimal formats of synergy between traditional and innovative models of learning. Based on already existing experience, extrapolation of conditions of educational process organization with modeling realities of using information and communication technologies in various learning dimensions should be carried out. Educational trends for the next 3 years are a rather tentative forecast because, as demonstrated by the events associated with the COVID-19 pandemic, the socio-cultural space is very changeable. Consequently, the dynamism of the educational environment dictates the need for a value-based awareness of the information society and the practical use of technological advances. Thus, information and communication technologies are a manifestation of innovative educational strategies of today and become an important component along with traditional aspects of educational process organization. Future higher education teachers should develop a training strategy taking into account the expediency of the ICT component.

E-commerce in Korea has grown steadily in recent years. E-commerce has provided firms with an effective method to approach potential customers by overcoming geographical and physical barriers. However, despite the rapid growth, many e-commerce businesses closed their businesses and were not able to survive. This study aims to empirically examine the factors that determine the survival of e-commerce businesses in Korea. In particular, this study focuses on the factors related to the notion of institution-based trust that includes delivery, privacy, and security management. This research used the data set about 31,295 e-commerce businesses that have been registered in Seoul. We found that the e-commerce business that does not require extra personal information beyond the standard terms and conditions or provides a feedback mechanism by having an online board to submit a complaint has a higher chance of survival. In addition, the e-commerce business that has a secured web server, shows the specific information about the date of delivery, or provides escrow services is likely to survive longer than others. The research has extended the extant literature on the importance of trust in e-commerce by empirically examining the effects of the institution-based trust factors on the actual survival of e-commerce businesses.

Background: This study was aimed at investigating factors influencing the selection of dental institutions for implant surgery among young adults (age: 20-64 years) and identifying differences in these factors according to general characteristics. Methods: We conducted an internet survey for approximately 2 months, from April to July 2022, and analyzed data from a total of 128 people. Dental institution selection factors included three items of convenience of transportation, five items of physical environment, three items of image of institution, five items of image of dental staff, five items of dental service, and four items of basic dental elements. The importance score for each item was investigated on a five-point scale. Results: The importance score for each dental institution selection factor was the highest for dental service (4.42 points), followed by basic dental element (4.00 points), physical environment (3.89 points), image of institution (3.81 points), convenience of transportation (3.76 points), and image of dental staff (2.78 points). The importance score for each item was the highest for dentists' technique, followed by cleanliness, reliability, and dentists' attitude. Women had higher average scores for all factors compared to men, with statistical significance in scores for convenience of transportation, physical environment, image of institution, dental service, and basic dental elements (p< 0.05). Conclusion: To attract patients seeking implants to a dental institution, attention should be paid to the patients' institution selection factors. In addition, the environment of a dental institution should be created in such a way that it favors patients' selection factors.

Objective: To develop a deep-learning-based bone age prediction model optimized for Korean children and adolescents and evaluate its feasibility by comparing it with a Greulich-Pyle-based deep-learning model. Materials and Methods: A convolutional neural network was trained to predict age according to the bone development shown on a hand radiograph (bone age) using 21036 hand radiographs of Korean children and adolescents without known bone development-affecting diseases/conditions obtained between 1998 and 2019 (median age [interquartile range {IQR}], 9 [7-12] years; male:female, 11794:9242) and their chronological ages as labels (Korean model). We constructed 2 separate external datasets consisting of Korean children and adolescents with healthy bone development (Institution 1: n = 343; median age [IQR], 10 [4-15] years; male: female, 183:160; Institution 2: n = 321; median age [IQR], 9 [5-14] years; male: female, 164:157) to test the model performance. The mean absolute error (MAE), root mean square error (RMSE), and proportions of bone age predictions within 6, 12, 18, and 24 months of the reference age (chronological age) were compared between the Korean model and a commercial model (VUNO Med-BoneAge version 1.1; VUNO) trained with Greulich-Pyle-based age as the label (GP-based model). Results: Compared with the GP-based model, the Korean model showed a lower RMSE (11.2 vs. 13.8 months; P = 0.004) and MAE (8.2 vs. 10.5 months; P = 0.002), a higher proportion of bone age predictions within 18 months of chronological age (88.3% vs. 82.2%; P = 0.031) for Institution 1, and a lower MAE (9.5 vs. 11.0 months; P = 0.022) and higher proportion of bone age predictions within 6 months (44.5% vs. 36.4%; P = 0.044) for Institution 2. Conclusion: The Korean model trained using the chronological ages of Korean children and adolescents without known bone development-affecting diseases/conditions as labels performed better in bone age assessment than the GP-based model in the Korean pediatric population. Further validation is required to confirm its accuracy.

Objectives: The purpose of this study was to analyze the factors affecting antibiotic prescription in dental outpatients. Methods: The present study was conducted using data from the National Health Insurance Service - National Sample Cohort. We analyzed prescriptions issued in the dental outpatient department in 2015, for adults over 19 years of age. Antibiotic prescription rates and mean prescription days were analyzed by sex, age, insurance type, presence of diabetes mellitus and hypertension, season in treatment, type of dental institution, and location of dental institution. Multivariate logistic regression was also performed to analyze the factors affecting antibiotic prescription in dental outpatients. Results: A total of 257,038 prescriptions were analyzed. The mean prescription days of antibiotics in dental outpatients were $3.04{\pm}1.08days$, and the prescription rate was 93.0%. Two variables (presence of diabetes mellitus and insurance type) were excluded from the multivariate logistic regression analysis model because they did not significantly affect antibiotic prescription. The possibility of antibiotic prescription was higher in men ${\geq}61years$ of age and those with hypertension. Furthermore, antibiotics were most frequently prescribed in dental clinics rather than dental hospitals, and more frequently in Busan compared to other areas (p<0.001). Conclusions: Several factors were determined to affect antibiotic prescription, and detailed guidelines for consistent antibiotic prescription are needed.
