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.

현재 보안관제 시장은 AI기술을 기반으로 하여 운영 중이다. AI를 사용하는 이유는 보안장비간 대량으로 발생하는 로그와 빅데이터에 대해 이를 탐지하기 위해 사용하고, 시간적인 문제와 인적인 문제를 완화하기 위해서 이다. 하지만 AI를 적용함에도 문제는 여전히 발생하고 있는 중이다. 보안관제 시장은 이 논문에서 소개하는 문제점 말고도 많은 문제점과 대응하고 있으며, 본 논문은 다섯 가지의 문제점을 다루고자 한다. 'AI 모델 선정', 'AI 표준화 문제', '빅데이터의 정확성 및 신뢰성', '책임소재의 문제', 'AI의 타당성 부족' 등 보안관제 환경에 AI기술을 적용함에도 발생하는 문제점을 고찰하고자 한다.

"Soayakjeungjikgyeol(小兒藥證直訣)" written by Jeon Uel(錢乙, 1032-1113) in the Song dynasty, is the most old and well know specialty publication of pediatrics in Easter Traditional Medicine. "Soayakjeungjikgyeol(小兒藥證直訣)" made a big influence not only on the development of pediatrics in later traditional medicine through the explanations of physiological and pathological knowledge and experiences, but also on application of many effective prescriptions which have been used in many clinics until now days. One of the most important meaning which "Soayakjeungjikgyeol(小兒藥證直訣)" has, is that it emphasized on the diagnosis and treatment using the theory of five organs(五臟辨證), and applied it to clinical medicine effectively. In othe words, through application of the theory of five organs in "Hwangjenargyeong(黃帝內經)" to practical field, Jeon Uel(錢乙) played role of a ring connecting with studies of herbal medicine in the school of Yeoksu(易水), and the development of the theory of five organs of the four prominent doctors(金元四大家) in the Jin(金) and Yuan(元) dynasty. In this article, also it is investigated that how the theory of interaction among five phases(五行), can be applied to treatment of pediatrics through analysis of related texts in "Soayakjeungjikgyeol(小兒藥證直訣)". This studies would be useful to understanding the history and properties of the theory of five organs.
