( Jaewoong Moon ),( Subin Kim ),( Jaeseung Song ),( Kyungshin Kim ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.12
The importance and necessity of artificial intelligence, particularly machine learning, has recently been emphasized. In fact, artificial intelligence, such as intelligent surveillance cameras and other security systems, is used to solve various problems or provide convenience, providing solutions to problems that humans traditionally had to manually deal with one at a time. Among them, information security is one of the domains where the use of artificial intelligence is especially needed because the frequency of occurrence and processing capacity of dangerous codes exceeds the capabilities of humans. Therefore, this study intends to examine the definition of artificial intelligence and machine learning, its execution method, process, learning algorithm, and cases of utilization in various domains, particularly the cases and contents of artificial intelligence technology used in the field of information security. Based on this, this study proposes a method to apply machine learning technology to the method of classifying and detecting malware that has rapidly increased in recent years. The proposed methodology converts software programs containing malicious codes into images and creates training data suitable for machine learning by preparing data and augmenting the dataset. The model trained using the images created in this manner is expected to be effective in classifying and detecting malware.
Chronic Intestinal Pseudo-Obstruction Caused by Intestinal Adenocarcinoma in a Mixed-Breed Dog

A 9-year-old, mixed-breed, castrated male dog presented with a one-week history of severe vomiting. Abdominal radiography showed a dilated small intestine loop. Abdominal ultrasonography showed small-intestinedistension up to 5 cm in diameter without mechanical obstruction. During exploratory laparotomy, an aperistaltic ilealsegment was resected. There was no narrowed cavity in the resected plane. Histopathologic and immunohistochemicalfindings confirmed visceral myopathy due to intestinal adenocarcinoma in the ileum and revealed partial destructionof the longitudinal and circular muscles with fibrosis. Chronic intestinal pseudo-obstruction caused by adenocarcinomawas diagnosed after considering the above investigative results.
