This Study aims to propose a new information security governance model design method for streamlining security governance at national strategic level. The research method of this study is to diagnose our operational experience and to derive a new model design method. In the meantime, national information security activities were perceived to be focused on knowledge transfer, and motivation of activities and securing of executive power were weak. As a result, security blind spots and frequent occurrence of large security incidents have become unresolved challenges. National cyber security governance should be grouped together as a whole systematically from the upper policy to the lower level of performance under the responsibility of the national leader. Based on this approach, this study presented the comprehensive framework of Korean security governance model and embodied it into four architectural designs such as vision, goal, process, and performance, thus deriving the foundation for future national governance model design. Further research is needed to diagnose problems in life cycle flow, security policies based on environmental changes, and new frameworks in which all subjects participate.

As the incidence and prevalence of dementia increases with our aging population, so does the social burden on our society, which calls for a special emphasis on need for early diagnosis. Thus, efforts are made to prevent dementia and early detection but with current diagnostic measures, these efforts appear futile. As a solution, it is crucial to integrate and standardize healthcare big data and analysis of each index. In order to increase use of large database, the Korea National Assembly passed the Data 3 Act focusing on open-access and sharing of database, but a follow-up legislation is needed a for safer utilization. In this study, we have identified number of foreign of foreign policies through review of prior researches on the topic leading to specific enforcement ordinances tailored to the Data 3 Act for safe access and utilization of database. We also aimed to establish secure process of data collection and disposal as well as governance at the national level to ensure safe utilization of healthcare big data.

The purpose of this study was to analyze the management behavior in patients with hypertension and diabetes through the total inspection of a specific rural area. Data was collected through self-administered questionnaires from May 19th to September 21st in 2014. As the result, Among 355 (36.6%) patients who were diagnosed with hypertension, 337 (94.9%) were currently undergoing treatment, and among 109 (11.2%) patients who were diagnosed with diabetes mellitus, 96 (80.1%) were currently undergoing treatment. Among the total of 211 people in hypertension potential risk group, 89 (42.2%) were diagnosed with hypertension, and among the total of 356 people in hypertension potential risk group, 78 (22.0%) were diagnosed with diabetes mellitus. In conclusion, from the results of the analysis, we suggest that effective national strategies for prevention and management for patients with hypertension and diabetes should be established and implemented.

This study proposes a more comprehensive approach for FLD by analyzing the relationship of colorectal polyps, which are precursors of colorectal cancer. In Chi-Square tests of FLD and colorectal polyps, the prevalence of colorectal polyps was significantly high in cases of FLD. The polyps and correlation of each factor showed a positive relationship with all factors, and the correlation coefficient with FLD was highest (r = 0.39, p <.001). In multiple regression analysis, FLD(OR 3.80 95% CI 1.93.-7.50), FBS (OR 2.51; 95% CI 1.12-5.62), and older age (OR 2.12; 95% CI 1.27-3.54) were independent risk factors for colorectal polyps. FLD was associated with the prevalence of colorectal polyps. These results show a meaningful influenceof FLD by ultrasonography in the occurrence of colorectal polyps, and that positive consideration of colonoscopy is needed for diagnosed FLD.

SSE-CMM for security engineering, engineering, assurance, risk is divided into three elements of the process maturity assessment model and the level of information security presented. Maturity measurement of privacy, vulnerability diagnosis and risk analysis methodologies is used in practical field for present a comprehensive conclusion. The common cyber services are internet banking, mobile banking, telephone banking and the like. Transaction structure, a kind of cyber-banking system, information security maturity of the existing measurement methodologies for research purposes, vulnerability diagnosis and risk analysis methodologies to be used in practical field present a comprehensive conclusion. To ensure safety and convenience for the user, convenient to deal with cyber environment is the key to the activation of cyber trading. Particularly by measuring the maturity of cyber banking system to ensure the safety of the practice field much effects are expected as a result.

This study was to understand the relationship between emergency room visit due to illness and personal health behaviors as well as population and illness characteristics of elderly patients with diabetes. This study was a descriptive correlation study that analyzed 956 respondents aged 65 or older and diagnosed with diabetes in the Korean Health Panel's data from 2014 to 2017. Data were analyzed using the SPSS 26.0 program with Mann-Whitney U test, chi-square test, and logistic regression analysis. The respondents who visited emergency room had fewer days of moderate-intensity physical activity and walking activity, were older, had activity restrictions due to disability, had depression, and had a large number of comorbid chronic diseases. In order to prevent elderly people with diabetes from visiting emergency room, it is important to encourage moderate-intensity activity and walking.

The purpose of this study is examine the validity of digital competency indicators in order to develop a tool that can measure the digital competency of preschool teachers. To review the validity, exploratory factor analysis and confirmatory factor analysis were conducted on the data of 272 preschool teachers. The exploratory factor analysis resulted in four factors, and the confirmatory factor analysis verified the fit, validity(convergent validity, discriminant validity) and reliability of each competency group and the model composition of sub-competency indicators. The four factors validated were named 'Understanding Digital Technologies', 'Digital Technology Understanding', 'Digital Technology Application', 'Digital Technology-based Communication', 'Digital Ethics Understanding and Practice'. The analysis results demonstrated the reliability and validity of the tool for measuring the digital competencies of preschool teachers, and it is meaningful in that it can provide a foundation for measuring the digital competency of preschool teachers and conducting education program suitable for each digital competency level.

To diagnose a patient's blood vessel disease, apoplexy, hypertension, arteriosclerosis, the blood velocity is very important. Determining the blood velocity methods using ultrasound are Continuous Doppler System and Pulse Doppler System. In using the Pulse Doppler System, we can obtain the position of blood velocity. But it is more complex hardware than Continuous Doppler System and it has low SNR(signal-noise ratio). So in this study, to obtain a believable information we use the Continuous Pulse Doppler System. Thus system have analog part and digital part. In analog part is composed of ultrasound generating part, the amplifying part to amplify the received signal from ultrasound sensor, the demodulation part to detect blood velocity and the filtering part to remove the noise. In digital part is composed of the A/D conversion part, digital signal processing part, and the communication part to communicate the PC. In this study to implement efficient ultrasound blood velocity measurement system, we can get the patient's blood velocity information in realtime. Thus, It is a useful in the accurate diagnosis with C.T(computered tomography), M.R.I(magnetic resonance imaging).
