Purpose : To examine the relationship among osteoporosis knowledge, osteoporosis preventive behaviors, self-efficacy and health-related quality of life of middle aged women and to find out factors which influence health-related quality of life. Methods : For study subjects, female patients aged 40 to 64 and hospitalized at the surgical wards of two general hospitals in G city were conveniently sampled. The data have been collected from January 11 to March 10, 2018. Data were analyzed by descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and multiple regression. Results : The average score of osteoporosis knowledge was 12.50±3.47, the average score of osteoporosis preventive behaviors was 44.96±8.16 and the average score of osteoporosis self-efficacy was 40.38±8.07. The factors influencing EQ-5D Index in health-related quality of life were comorbidity, osteoporosis preventive behaviors, osteoporosis knowledge and average monthly income, which could account for health-related quality of life at 18.0%. The factors influencing EQ-5D VAS were osteoporosis preventive behaviors, self-efficacy, osteoporosis knowledge and age of menarche, which could account for health-related : Higher osteoporosis knowledge, osteoporosis preventive behaviors and self-efficacy, the better the subjects health-related quality of life. Therefore, as a way to promote health-related quality of life of middle aged women, the constant development and the application of a program which may promote osteoporosis knowledge, osteoporosis preventive behaviors and self-efficacy are needed.

본 논문에서는 네트워크 카메라를 이용한 물체 감시 및 비정상 행위의 판단을 위한 실시간 시스템을 제안한다. 제안된 시스템은 먼저 물체의 감시를 위해 SIFT 알고리즘에 기반으로 감시 물체의 특징 정보를 DB화 하고, 히스토그램(Histogram)기법을 활용하여 감시지역을 설정한다. 또한 인간의 행동 및 비정상 행위를 판단하기 위하여, 가상 인간 스켈레톤 모델을 이용하여 입력된 영상에서의 인간의 특징점을 추출한다. 추출된 특징점을 바탕으로 PCA(Principal Component Analysis)를 이용하여 인간의 움직임을 보다 정확하게 표현할 수 있는 특징벡터를 생성하였다. 생성된 특징벡터를 기반으로 퍼지분류기를 이용하여 인간의 행동을 분류하고, 생성된 특징벡터와 특정물체의 거리를 기반으로 인간의 비정상행위를 판단한다. 제안된 방법은 실험을 통해 시스템의 응용 가능성을 증명한다.

특정 기업 및 국가를 대상으로 하는 APT(Advanced Persistent Threat)공격의 경우 특정 시스템을 겨냥하여 제작되기 때문에 기존의 시그니처 기반의 악성코드 탐지 방식으로는 해당 악성코드를 탐지할 수 없다. 따라서 알려지지 않은 악성코드를 탐지할 수 있는 행위 기반의 악성코드 탐지 방식이 최근 이슈화되었다. 본 논문에서는 연구되고 있는 행위 분석 기반의 악성코드 탐지 방식들을 분석함으로써 향후 행위 기반 악성코드 탐지 기술 개발 및 연구에 기여하고자 한다.

농업계는 농업정책자금과 보조금 유용 문제가 발생하지 않도록 주의해야 할 것이다. 불경기에는 다른 사람을 배려하는 마음이 약해지고, 자신의 이익을 챙기는 마음이 강해진다. 쌀 직불금의 부당수령이나 면세유 불법유통과 같은 세금 유용 행위에 사람들은 더 분노하게 된다. 몇 사람이 저지른 잘못으로 농업계가 매도당하지 않도록 해야 할 것이다. 사람들은 불경기에서 빨리 벗어날 수 있다면 영혼이라도 팔려고 할지 모른다. FTA가 불경기 탈출에 도움이 된다면 마다하지 않을 것이다.

This paper gives analyses on the historical origin where features from social punishment and re-socialization in North Korea have been developed. The process of the development largely consists of three periods, that is, the period of nation construction (1945-1950), the period of Korean War (1950-1953), the period of nation reconstruction (1950-1961). This paper provides that features from punishment and re-socialization have been developed during the historical transformation from pre-Korean War to post-Korean War. The 'wartime socialism system' had been established in the course of reconstruction of postwar nation. In the system, North Korean had been embraced into the structure of re-socialization in its production unit and living space.

At present, due to the rapid spread of smartphones and activation of IoT, malicious codes are disseminated using SNS, or intelligent intrusions such as intelligent APT and ransomware are in progress. The damage caused by the intelligent intrusion is also becoming more consequential, threatening, and emergent than the previous intrusion. Therefore, in this paper, we propose an intelligent intrusion situation-aware reasoning system to detect transgression behavior made by such intelligent malicious code. The proposed system was used to detect and respond to various intelligent intrusions at an early stage. The anticipated system is composed of an event monitor, event manager, situation manager, response manager, and database, and through close interaction between each component, it identifies the previously recognized intrusive behavior and learns about the new invasive activities. It was detected through the function to improve the performance of the inference device. In addition, it was found that the proposed system detects and responds to intelligent intrusions through the state of detecting ransomware, which is an intelligent intrusion type.

The purpose of this study was to determine the effect of sedentary time on quality of life and oral health-related behaviors using the Korean National Health and Nutrition Examination Survey. A total of 19,983 data were analyzed using the IBM SPSS 25.0 program, and complex sample logistic regression analysis was performed to confirm the effect of sedentary time on health-related quality of life and oral health-related behaviors. As a result, the longer the sitting time, the worse the quality of life (p<.05). There was an increase in the number of cases of not brushing (p<.05). Also, as for dental treatment, the longer the sitting time, the more prophylactic treatment and periodontal treatment increased (p<.05). Therefore, it is judged that it can be used as basic data to improve the quality of life and increase oral health-related behaviors in consideration of the socio-demographic characteristics of prolonged sedentary time.

This paper reviews how electronic media technologies involve and produce time-space dimensions in geometrical spaces, focusing on four theoretical perspectives: van Dijk's dual structure of networks as scale extension and reduction; Latour's actor-networks as fluid and hybrid networks; Virilio's dromospherical time as global media vectors; and Castells' timeless time as non-sequential flows. In these four theoretical perspectives, we can see that electronic media technologies involve different and multiple time-space dimensions in geometrical media spaces: from the two-dimensional spaces (surfaces) of concentric circles, through the one-dimensional spaces (lines) of actor-networks to the zero-dimensional spaces (points) of dromospherical time and finally to the multi-dimensional spaces (hypertexts) of timeless time. The paper concludes by suggesting that we need to explain electronic media spaces not only in terms of geometrical media spaces but also in terms of geographical media spaces in order to understand the ways in which electronic media spaces are dis/embedded in geographical spaces.

The purpose of this study was to assess treatment-seeking behavior and to identify the factors that affect treatment-seeking behavior of men having lower urinary tract symptoms. One hundred thirty-two men working at public institutions or visiting the public institutions were included for this study. Data were collected through a structured questionnaire survey done from October to November, 2016. Data were analyzed using SPSS/WIN 18.0 program. The treatment-seeking behavior was found only in 55.6% (n=79) with lower urinary tract symptoms. The factors that affect treatment-seeking behavior in men with lower urinary tract symptoms significantly were economic status, subjective health status, autonomy, and competence. Results of this study provided fundamental data for developing the program to promote treatment-seeking behavior in men with lower urinary tract symptoms.
