Background: Research on carcinogens causing occupational cancer has been updated. Further, social interest in occupational cancer has increased. In addition, the standard for recognizing cancer as a work-related disease has also been revised. The present study aims to describe the distribution of occupational cancer claims or its approval rate and their association with work-related variables. Methods: We analyzed 1299 claim cases for occupational cancer from 2010 to 2016 provided by the Korea Workers’ Compensation and Welfare Service (KCOMWEL). The status of approval rate was shown by year, sex, industry, occupation, age of diagnosis, duration from employment to diagnosis, and cancer site. Results: The approval rate was 39.0% from 2010 to 2016 and tended to increase annually since 2011. Both the number of claims and the approval rate were higher in men. Mining and quarrying showed the highest approval rate (78.4%). The approval rates by age of diagnosis and duration from employment to diagnosis increased as the time periods increased. Respiratory organ had the highest number of claims and the highest approval rate by cancer site. Conclusions: The approval rate of occupational cancer has shown an increasing trend since 2011. The increase of occupational carcinogens and cancer sites and the improvement of social awareness about occupational cancer could have resulted in this trend. The present study provides unique, and the latest and most accurate findings on occupational cancer data of recent 7 years that could be helpful to researchers or policy makers on occupational cancer.

The purpose of this study is to investigate incorrect posture and to give awareness of Malalignment Syndrome due to prolonged incorrect posture among university students. A total 256 H university students participated in this study. Results from the Digital Thermal Scanner demonstrated the prevalence of Malalignment Syndrome to be (56.6%) among university students. A higher percentage of women (51.7%) were found to have Malalignment Syndrome than men. Furthermore, complications of Malalignment Syndrome were more common in women. Students in lower academic years were found to have a higher rate of Malalignment Syndrome. Overall, students majoring in Dental Hygiene had the highest occurrence of Malalignment Syndrome (95%). There is a pressing need for early prevention and care for university students in their early twenties, since this is an important period of life for maintaining long term health and forming good health habits.

실생활의 사례를 바탕으로 생성된 여러 분야의 데이터셋을 기계학습(Machine Learning) 문제에 적 용하고 있다. 정보보안 분야에서도 사이버 공간에서의 공격 트래픽 데이터를 기계학습으로 분석하는 많은 연구들이 진행 되어 왔다. 본 논문에서는 공격 데이터를 유형별로 정확히 분류할 때, 실생활 데이터에서 흔하게 발생하는 데이터 불균형 문제로 인한 분류 성능 저하에 대한 해결방안을 연구했다. 희소 클래스 관점에서 데이터를 재구성하고 기계학습에 악영향을 끼치는 특징들을 제거하고 DNN(Deep Neural Network) 모델을 사용해 분류 성능을 평가했다.

이동성을 가지는 네트워크 환경이 발생하면서 이를 지원하기 위한 이동 네트워크(NEtwork MObility) 프로토콜이 설계되었다. 하지만 표준 이동 네트워크 기술은 라우팅시에 최적화된 경로를 통하여 패킷이 전달되지 못하는 문제점이 있다. 이를 해결하기 위한 이동 네트워크 경로 최적화 기법이 많이 연구되고 있는데 멀티호밍(multihoming) 환경을 고려하여 경로 최적화를 할 경우 더욱 좋은 성능을 향상을 기대할 수 있다. 이 논문에서는 멀티호밍 이동네트워크 환경에서 내부 경로 최적화를 통하여 성능을 향상시킬 수 있는 기법을 제시한다.
