  • This study conducted a comparative experiment on the continuity of time series data and the classification performance of artificial intelligence models. In BCI research using EEG signals, the performance of behavior and thought classification improved as the continuity of the data decreased. In particular, LSTM achieved a high performance of 0.8728 on data with low continuity, and DNN showed a performance of 0.9178 when continuity was not considered. This suggests that data without continuity may perform better. Additionally, data without continuity showed better performance in task classification. These results suggest that BCI research based on EEG signals can perform better by showing various data characteristics through shuffling rather than considering data continuity.

  • Data Mining is mainly used for pattern extracting and information discovery from collected data. However previous methods is difficult to reflect changing patterns with time. In this paper, we introduce Streaming Decision Tree(SDT) analyzing data with continuity, large scale, and changed patterns. SDT defines continuity data as blocks and extracts rules using a Decision Tree's learning method. The extracted rules are combined considering time of occurrence, frequency, and contradiction. In experiment, we applied time series data and confirmed resonable result.

  • This study aimed to unveil the causality between the emotional marketing of aesthetic salons and brand awareness/relationship continuity in Chinese female consumers. For data collection, a self-administered questionnaire survey was conducted among adult women in their 20s or older in Liaoning Province, China, from February 2 to 18, 2023, using WeChat. From a total of 431distributed questionnaires, 393 copies were collected. Then, 369 copies, excluding 24 poorly answered ones, were used for the final analysis. The collected data were analyzed using SPSS 25.0 and the summary of the results of the study is as follows. First, in emotional marketing, sight, smell, hearing, and taste had a positive(+) influence on both cognitive and affective experiences. Second, in emotional marketing, sight, smell, and taste displayed a positive(+) effect on relationship continuity. Third, in brand awareness, both cognitive and affective experiences showed a positive(+) effect on relationship continuity. Collectively, this means that the higher the cognitive and emotional marketing of brand awareness, the higher the relationship continuity persistence. This study confirmed the causality among the emotional marketing of aesthetic salons, brand awareness, and relationship continuity; sight and taste were key factors that influenced brand awareness and relationship continuity. In addition, hearing and smell were important, influencing the relationships among variables.

  • Since most of companies these days are utilizing the Information system actively, Information System is the most important factor which should be recovered in terms of Business Continuity. However, a lot of enterprises have been outsourcing their Disaster Recovery Center. Therefore, it is highly possible that the information system can not work well and result in the discontinuity of business when any trouble arises because of seperated plan of Business Continuity and Disaster Recovery. The study draws critical success factors for successful disaster recovery through researches of 42 documents. Then, factors are reviewed through interviews with consultants, experts of Business Continuity Plan and the information system officers of domestic banks. Domestic companies can make use of the study when they develop or renew Disaster Recovery Plan or Information System in terms of Business continuity.

  • Purpose This study aims to investigate factors that positively influence the continuous Artificial Intelligence(AI) Learning Continuity of business major students. Design/methodology/approach To evaluate the impact of AI education, a survey was conducted among 119 business-related majors who completed a software/AI course. Frequency analysis was employed to examine the general characteristics of the sample. Furthermore, factor analysis using Varimax rotation was conducted to validate the derived variables from the survey items, and Cronbach's α coefficient was used to measure the reliability of the variables. Findings Positive correlations were observed between business major students' AI Learning Continuity and their AI Interest, AI Awareness, and Data Analysis Capability related to their majors. Additionally, the study identified that AI Project Awareness and AI Literacy Capability play pivotal roles as mediators in fostering AI Learning Continuity. Students who acquired problem-solving skills and related technologies through AI Projects Awareness showed increased motivation for AI Learning Continuity. Lastly, AI Self-Efficacy significantly influences students' AI Learning Continuity.

  • Objectives : The objectives of this study were to estimate the continuity of care for all Koreans with diabetes and to identify factors affecting the continuity of care. Methods : We obtained National Health Insurance claims data for patients with diabetes who visited health-care providers during the year 2004. A total of 1,498,327 patients were included as study subjects. Most Frequent Provider Continuity (MFPC) and Modified, Modified Continuity Index (MMCI) were used as indexes of continuity of care. A multiple linear regression analysis was used to identify factors affecting continuity of care. Results : The average continuity of care in the entire population of 1,498,327 patients was $0.89{\pm}0.17$ as calculated by MFPC and $0.92{\pm}0.16$ by MMCI. In a multiple linear regression analysis, both MFPC and MMCI were lower for females than males, disabled than non-disabled, Medicaid beneficiaries than health insurance beneficiaries, patients with low monthly insurance contributions, patients in rural residential areas, and patients whose most frequently visited provider is the hospital. Conclusions : The continuity of care for patients with diabetes is high in Korea. However, women, the disabled and people of low socio-economic status have relatively low continuity of care. Therefore, our first priority is to promote a diabetes management program for these patients.

  • Background: The most important thing to strengthen primary care is to prove that the continuity of primary care is an essential area for good health outcomes. The purpose of this study is to analyze the effect of outpatient continuity of primary care on the hospitalization experience of diabetes mellitus in new diabetic patients. Methods: Using the Korean National Health Insurance Service national sample cohort (NHIS-NSC 2011-2015) data, 3,391 new diabetic patients in 2012 were selected for the study. Multiple logistic regression was performed to investigate the effect of outpatient continuity of primary care on hospitalization in new diabetic patients. Results: The outpatient continuity of primary care in new diabetic patients was measured by the continuity of care index, which showed that 69.4% (n=2,352) were high level and 30.6% (n=1,039) were low level. Patients who had high continuity of primary care at the early stage of diabetes diagnosis showed 3.49 times more likely to maintain high continuity of primary care in the second year (95% confidence interval [CI], 2.72-4.49). Patients with low continuity of primary care for 2 years from the initial diagnosis of diabetes were 2.56 times more likely to be hospitalized due to diabetes than those who did not (95% CI, 1.55-4.25). Conclusion: This study identified the need for policies to increase the continuity of primary care for new diabetic patients and could contribute to lowering the admission rate of diabetic patients if the policy for this would work effectively.
