The purpose of this study is to develop a composite platform for knowledge extractions, visualizations, and inference. Generally, the big data sets were frequently used in the healthcare and medical area. To help the knowledge managers/users working in the field, this study is focused on knowledge management (KM) based on Data Mining (DM), Knowledge Distribution Map (KDM), Decision Tree (DT), RDBMS, and SQL-inference. The proposed mechanism is composed of five key processes. Firstly, in Knowledge Parsing, it extracts logical rules from a big data set by using DM technology. Then it transforms the rules into RDB tables. Secondly, through Knowledge Maintenance, it refines and manages the knowledge to be ready for the computing of knowledge distributions. Thirdly, in Knowledge Distribution process, we can see the knowledge distributions by using the DT mechanism.Fourthly, in Knowledge Hierarchy, the platform shows the hierarchy of the knowledge. Finally, in Inference, it deduce the conclusions by using the given facts and data.This approach presents the advantages of diversity in knowledge representations and inference to improve the quality of computer-based medical diagnosis.

Purpose: The great toe presents a reconstructive challenge for plastic surgeons. The big toe has much importance not only for the gait and the stability, but also for appearance aspects. Few reports have documented the reconstruction of big toe defects and we report a unique case of free flap reconstruction technique. Methods: A 41-year-old man with right great toe open fracture with soft tissue necrosis was referred from the orthopedic surgery department. On physical examination, there was the skin necrosis circumferentially and the fratured bone was severely fragmented. The metatarsophalangeal (MTP) joint of the big toe was intact. After the wound debridement, we harvested the innervated anterolateral thigh flap and transposed to the defected area. After five months, we finally retouched the flap by the dorsal defatting and distal debulking. Results: He had an uneventful postoperative course without infection, dehiscence and flap necrosis. He has remained asymptomatic for eight months without any recurrence such as the osteomyelitis. Finally, he kept the normal gait and posture with weight bearing on the reconstructed great toe and foot. Conclusion: The anterolateral thigh flap is described for the reconstruction of the great toe. It involves two stage procedure with the minimal donor site morbidity and provides a good cosmetic result.

The purpose of this research is to investigate the characteristics of big data-based fashion shopping (BDFS) application, perceived usefulness, and expectation confirmation that influence the continuous usage intention of BDFS application users based on the expectation-confirmation model. A survey was conducted with female consumers in their 20s, who are living in Seoul and Incheon area and have used BDFS applications, A total of 182 responses were used for the data analysis. Five hypotheses were proposed, and regression analyses were conducted to test those hypotheses. The results indicated that the users' perceived usefulness increased with the increase of accuracy and personalization characteristics of the app and the expectation confirmation. The result suggested that it is essential to provide accurate information for users to feel useful and to develop the personalized offerings and services which can be the biggest strength of the big-data based mobile fashion store. It was also found that continuous usage intention increases with increased perceived usefulness and expectation confirmation. This result suggests that expectations can play a critical role in perceiving the usefulness of BDFS applications and the user's expectation confirmation also significantly affected the users' continuous usage intention.

Currently, the security control market is operating based on AI technology. The reason for using AI is to detect large amounts of logs and big data between security equipment, and to alleviate time and human problems. However, problems are still occurring in the application of AI. The security control market is responding to many problems other than the problems introduced in this paper, and this paper attempts to deal with five problems. We would like to consider problems that arise in applying AI technology to security control environments such as 'AI model selection', 'AI standardization problem', 'Big data accuracy', 'Security Control Big Data Accuracy and AI Reliability', 'responsibility material problem', and 'lack of AI validity.'

The objective of this study was to search the effect of individual personality (big five personality) on creative behavior. In particular, we tried to find out how the individual characteristics of the students who are perceived as unique majors in university and students who are in non-art, music and physical education affect the creative behavior. To perform this, questionnaires were distributed to 150 university students in art, music and physical education and 150 non-art, music, and physical education university students in C University located in Gwangju Metropolitan City. 275 copies (91.7%) of valid questionnaires were used among them. As a result, extroversion, openness, Friendliness, and sincerity were found to affect creative behaviors, excluding neuroticism (emotional stability) among five factors of personality. Additional analysis was performed by departmentalizing the majors of respondents as art, music and physical education and non-art, music, and physical education. In the case of art, music and physical education, extroversion, openness, friendliness affected the creative behavior, and in the case of non-art, music and physical education, only extroversion and openness influenced creative behavior. This difference can be understood as the difference of habits according to major, and it has been proved that it is also similar to previous research results.
