This study aims to analyze what factors are associated with child care accreditation in Chungbuk province. This study examined three questions about which factors influence the accreditation of childcare centers: 1) if they passed the accreditation criteria, 2) the total score on the accreditation criteria, and 3) the domain scores for the six domains of environment, management, process, interaction and teaching, health and nutrition, and safety. The characteristics of 1,212 childcare centers, the independent variables, were commit management, type, specialized service, maximum capacity of children, registration ratio, target age groups of children, duration, and city size. The formal expert committee evaluated objective scores for 952 childcare centers. I derived the data for this study from the i-sarang Childcare Information Portal site (http://info.childcare. go.kr/). Frequency, descriptive statistics, binary logit model, and OLS model analysis were used to examine the accreditation and scores by factors of childcare centers. The findings of the present study are as follows. First, about 80% of the 1,212 childcare centers in Chungbuk province were accredited. Second, the accreditation of the child care center was affected by the specialized service, registration ratio, and duration. Finally, the total score of accredited childcare centers was associated with the maximum capacity of children, registration ratio, and duration. The factors of childcare centers influencing sub-area scores were different by environment, interaction and teaching, health and nutrition, and safety. The present study is important because it offers preliminary data identifying accreditation characteristics that can judge problems related to the quality of service of childcare centers and suggest childcare policy implications.

In the past, control and monitor of a large number of instruments is a specialized area, which requires an expensive dedicated module to implement. However, with the recent development of embedded technology, various products capable of performing M&C (Monitor and Control) have been released, and the scope of application is expanding. Accordingly, it is possible to more easily build a small M&C environment than before. In this paper, we discussed a method to replace the M&C of the VLBI system, which had to be implemented through a specialized hardware product, with an inexpensive general imbeded technology. Memory based data transmission, reception and storage is a technology that is already generalized not only in VLBI but also in the network field, and more effective M&C can be implemented when some items of Ethernet are optimized for the VLBI (Very Long Baseline Interferometer) system environment. In this paper, we discuss in depth the design and implementation for the multidrop based IoT architecture.

Purpose: The aim of this study was to evaluate and compare the accuracy performance of dental professionals in the classification of different types of dental implant systems (DISs) using panoramic radiographic images with and without the assistance of a deep learning (DL) algorithm. Methods: Using a self-reported questionnaire, the classification accuracy of dental professionals (including 5 board-certified periodontists, 8 periodontology residents, and 31 dentists not specialized in implantology working at 3 dental hospitals) with and without the assistance of an automated DL algorithm were determined and compared. The accuracy, sensitivity, specificity, confusion matrix, receiver operating characteristic (ROC) curves, and area under the ROC curves were calculated to evaluate the classification performance of the DL algorithm and dental professionals. Results: Using the DL algorithm led to a statistically significant improvement in the average classification accuracy of DISs (mean accuracy: 78.88%) compared to that without the assistance of the DL algorithm (mean accuracy: 63.13%, P<0.05). In particular, when assisted by the DL algorithm, board-certified periodontists (mean accuracy: 88.56%) showed higher average accuracy than did the DL algorithm, and dentists not specialized in implantology (mean accuracy: 77.83%) showed the largest improvement, reaching an average accuracy similar to that of the algorithm (mean accuracy: 80.56%). Conclusions: The automated DL algorithm classified DISs with accuracy and performance comparable to those of board-certified periodontists, and it may be useful for dental professionals for the classification of various types of DISs encountered in clinical practice.
