The purpose of this study is to empirically examine the factors affecting the binge-watching behaviors of OTT service users by using a multi-layer perceptron (MLP) artificial neural network. All samples (n=1,000) were collected from 'A survey on user awareness in OTT service' published by a Media Research Center of the Korea Press Foundation in 2018. Our research model includes one dependent variable which is binge-watching behaviors on OTT service and five independent variables such as gender, age, frequency of service usage, users' satisfaction with content recommendation algorithm, and content types mainly consumed. Our findings demonstrate that age, frequency of service usage, users' satisfaction with content recommendation algorithms, and certain types of contents (e.g., Korean dramas, Korean films, and foreign dramas) were found to be highly related to binge-watching behavior on OTT services.

This study was to examine whether an elderly can health-related quality of life(EQ-5D) by the mediating effect of dental health determinants on the association between health practice behavior and EQ-5D. The analysis was conducted on 1,311 of above the age of 65 in elderly by using raw data from the 2015 National Health and Nutrition Survey. The data were analyzed using SPSS for windows version 24.0 and SPSS PROCESS-macro. The health practice behavior and EQ-5D by living arrangement were the highest in the one-generation family(4.62, 0.90) and the lowest the elderly living alone(4.40, 0.86). Also, analysis using the PROCESS macro indicated that the FS-T index has a mediating effect between health practice behavior and EQ-5D(${\beta}=.0011$, BCCI [.003~.0024]). These findings suggest that FS-T index is closely related to EQ-5D and this will be used as basic data for development of health promotion programs for elderly.

The purpose of this study was to examine relationships among health empowerment and health behavior compliance on quality of life and identify the factors that influence on quality of life in patients with coronary artery disease. Participants in this study were 180 patients with coronary artery disease in the Intervention of Cardiology of a general hospital in S city. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression using the SPSS Win. 22.0 program. The result of the multiple regression indicates the health behavior compliance, gender, health empowerment and educational level predict 23.4%(F=5.17, p=.024) in quality of life. Therefore, it is necessary to develop programs a health behavior compliance and health empowerment use specific strategies to improve quality of life for patients with coronary artery disease.

This study identified the impact of information literacy, risk perception, crisis communication on preventive behaviors related to COVID-19 among nursing students. Data were collected from 187 nursing students from 25 June 2020 to 3 July 2020, and analyzed using the SPSS/WIN 26.0 program. As a result of regression analysis, the factors influencing prevention behaviors were crisis communication(β=0.30, p<.001), information literacy(β=0.29, p<.001), and risk perception(β=0.19, p=.004). The explanatory power of the model was 27%. This study suggests that the focus should be on improving the activating crisis communication process among individual, family and society, increasing information literacy and risk perception on crisis when developing program to improve COVID-19 preventive behaviors of nursing students experiencing clinical practice.

Design restructuring improves software quality by reorganizing design elements and reduces maintenance cost. Object-oriented metrics can help to detect design flaws and find transformations to reorganize design elements. Basically, the transformations must preserve the behavior of an initial system. This paper describes a metric based restructuring technique preserving the behavior of object-oriented designs, founded on set theory, and gives its validity by applying the technique to applications written in Java. This paper also compares the technique with a technique using simulated annealing algorithm to show its effectiveness.

Malware는 인터넷 혹은 일반 네트워크사용자의 컴퓨터에 설치되어 의도하지 않은 악의적인 행위와 정보의 유출을 목적으로 하는 프로그램이다. Malware의 성향 분석은 Malware의 행위를 분석하는 것으로서 실제 Malware의 행위를 이용하여 가상의 Malware를 생성하고 두 Malware가 가지는 전파 과정상의 트래픽을 비교함으로써, 네트워크 상의 특성을 비교 및 검증할 수 있다. 본 논문에서는 Malware를 분석하고 가상 Malware를 제작하여 두 Malware가 발생하는 행위, 즉 네트워크 트래픽 데이터를 비교하여 가상의 Malware가 실제의 Malware와 동일한 네트워크 트래픽을 발생 시키는지 확인하기 위해 통계적인 모델링 기법인 GAM 을 이용해 비교 및 검증하는 방법에 대해 제안한다.

운영체제에서 기존의 접근통제 서비스는 조직의 보안 요구사항을 반영하여 기밀성과 무결성 등을 지원하였다. 하지만 많은 경우의 프로그램 수행 시간 공격(Program Runtime Attack)들은 행위적인 의미를 수반하며, 이는 개개의 접근 인스턴스가 아닌, 접근 인스턴스의 연속선에서 공격을 주시해야 한다. 대부분의 이러한 공격들은 실제 개개의 접근통제 인스턴스 측면에서의 보안 설정을 위반하지 않으며, 이것은 보안 통제에서 행위적인 측면의 제어가 부족한 연유로 기인한다. 본 논문에서는 보안 통제에서 접근제어와 더불어 행위제어가 가능한 확장된 참조모니터를 제안한다.

Purpose : The purpose of this study was to explore the subjective experiences of problem drinkers participating in the early intervention program for moderate alcohol drinking. Methods : A qualitative descriptive study design was used. Data were collected through individual interviews with thirteen problem drinkers and analyzed using qualitative content analysis. Results : The experiences of the problem drinkers participating in the early intervention program were derived from four themes and nine sub-themes in terms of awareness, alcohol expectancies, perceived self-efficacy and behavioral change. They participated in programs offered in the workplace, and there were differences in motivation level among individuals, but generally accepted the necessity of the program. Participants who had trust with the program provider were more likely to change drinking behavior. Conclusion : Problem drinkers who participated in the early intervention program showed that it is a useful approach to change the problem drinking behavior by promoting awareness of alcohol-related knowledge, motivation for change through acquiring enough information and acquisition of self-efficacy as a behavior skill. These findings can be used as basic information for implementing and adapting early intervention for prevention of alcoholism in primary health care setting including workplace.

Data were collected from September 1 to September 30, 2017 using a structural questionnaire, which was completed by 221 nursing students in G city. The data were analyzed though descriptive statistics, Pearson's correlation coefficient and multiple regression analysis using SPSS version 22.0. The mean scores were as follows: health promotion behaviors, $2.11{\pm}.34$; university life adaptation, $3.47{\pm}.67$; employment strategies, $3.24{\pm}.56$. A positive relationship was observed between the health promotion behaviors and university life adaptation (r=0.437, p<0.001), health promotion behaviors and employment strategies (r=0.536, p<0.001), and university life adaptation and employment strategies (r=0.615, p<0.001). Factors affecting employment strategies of the study participants were university life adaptation, health promotion behaviors, adaptation to environmental changes, and health conditions, which explained about 49.7% of the total. In conclusion, this study showed that employment strategies were correlated with promotion behaviors and university life adaptation. Therefore, it is necessary to improve curriculum, program development and repeat research to improve health promotion behaviors, university life adaptation and employment strategies.

The purpose of this study is to investigate hospital nurses' attitude toward migrant wives, the nurses' cultural knowledge, and their cultural nursing behavior, to analyze the relations between them, and to find the factors influencing their cultural nursing behavior. A questionnaire was given to 161 nurses in two general hospital in S city from April 1 to April 30, 2017. The results were evaluated by the SPSS/SIN 21.0 program. As a result, the hospital nurses' attitude toward immigrant wives scored 2.70 out of 4 points; cultural knowledge 0.51 out of 1 points; their cultural nursing behavior 3.04 out of 5 points. Cultural nursing behavior has significantly positive correlation with their cultural knowledge. Cultural knowledge, religion, and position in hospital were found to be the factors influencing their cultural nursing behavior. These influential factors explained their cultural nursing behavior 20.9%. In order to improve hospital nurses' cultural nursing behavior, it is necessary to provide continuous multi-cultural education to improve their knowledge, and to offer various convergence programs to give them more opportunities to interact multi-cultural persons.
