현재 많은 연구가 진행되고 있는 행위 기반 인증 기술은 다른 인증 기술들에 비해서 인증의 인식률을 높이는데 많은 데이터의 장기간 추출이 필요하다. 본 논문은 안드로이드 환경의 스마트폰에 내재되어있는 터치 센서와 자이로스코프를 이용하여 그동안의 행위 기반 인증 연구에서 사용 되었던 행위 특징 데이터들 중에서 핵심적인 최소한의 데이터들만을 이용하기 위해 사용자에게 다섯 차례의 측정을 요구하여 다섯 번의 터치스크린 화면을 터치 하는 방식으로 총 6가지의 행위 특징 데이터를 수집하였고 다음 터치 측정으로 넘어가는 동안의 데이터들의 변화 값에 평균 값을 구하여 이 값과 측정값의 코사인 유사도 측정을 수행하여 코사인 유사도 허용 범위를 생성 한 후, 인증 시도 데이터의 코사인 유사도 값과 비교하는 방식의 사용자 행위 기반 인증 방식을 제안한다. 본 논문을 통해서 적은 수의 특징 데이터와 실험자수 환경에서도 코사인 유사도 인증 범위에 적용되는 임계값을 조절하는 방식을 통해서 최초 EER 37.6%에서 최종 EER 1.9%의 높은 성능을 증명하는데 성공하였다.

Purpose: This study was conducted to identify the knowledge, attitude, and preventive health behavior of cancer in middle-aged men and to provide data for education program regarding cancer prevention. Methods: This study was a descriptive research using a questionnaire, which included 20 items for knowledge, 10 items for attitude, and 18 items for preventive health behavior of cancer. Data were collected from 140 middle-aged men. Descriptive statistics, t-test, one-way ANOVA and Pearson's correlation coefficients, and stepwise multiple regression analysis were used with SPSS/WIN 18.0 to analyze the data. Results: The mean score for knowledge of cancer was 11.58 (range 0~20), for attitude, 37.52 (range 5~50), and for preventive health behavior of cancer, 58.85 (range 18~90). Preventive health behavior of cancer showed a significantly positive correlation with knowledge (r=.27, p=.001) and attitude (r=.31, p<.001) toward cancer. In stepwise multiple regression analysis, knowledge and attitude toward cancer were significant factors affecting preventive health behavior of cancer. Those variables explained 12.5% of cancer preventive behavior. Conclusion: In order to develop a cancer prevention education program for middle-aged men, accurate knowledge and improving attitude should be considered. Furthermore, it is necessary to do further study with a larger random sample according to lifespan.

This study examined the effects of parental attachment and peer attachment in elementary school children upon early adolescent delinquency. The participants were 2,844 taken from data from the Korean Youth Panel Survey (KYPS). Data from secondary questionnaires data on parent and peer attachment, problem behavior, delinquent peers, and delinquency were used for this study. Data were analyzed by means of a Structural Equation Model using AMOS 5.0. Our results indicated that, firstly, parental attachment was negatively related to problem behavior for both male and female adolescents, whereas peer attachment was positively related to problem behavior only for males, but not for females. Secondly, problem behavior in childhood has a direct effect on adolescent delinquency, which also can be indirectly mediated by contact with delinquent peers. In conclusion, the path model from parental and peer attachment in early childhood to adolescent delinquency was supported only in the case of males.

The subject were 48 female students selected by theoretical sampling from a womens' university in Korea. The data were collected by in-depth interviews using audiotape recordings done over a period of seven months. The data were analyzed simultaneously by a constant comparative method in which new data were continuously coded into categories and properties according to strauss and corbin's methodology. Analysis of the data resulted in identification of 15 categories representing 34 concepts. The results of this study were as follows : 1. Smoking in college women is caused by either curiosity or antagonism toward male smokers 2. The meaning(phenomena) of smoking behavior in college women is justifiable or regretable 3. Smoking occurs in connection with eating, during period of psychological conflict or as an habitual practice 4. Smoking behavior is related to the perception of harmfulness to health, influence of others and the accessability of cigarettes. 5.

As the population of persons over the age of sixty-five is rapidly growing, the population of solitary senior person living at own home is growing in Japan. This situation has caused the social issue of how supports their healthy life. There have been some projects related to improve their quality of life and support their healthy life. Unfortunately mostly they focus the method of measuring vital signal and observing behavior. Nobody reports how utilize the measured data. Aim of our project is how find emergency of the aged people at home. As emergency is big different from regular life behavior, we have to recognize it. We propose concept of the human behavior model and show the some types human behavior knowledge constructed by observed human behavior model and show the some types human behavior knowledge constructed by observed human behavior. This idea is based on human having habitual life. And we discuss the possibility of finding emergency using knowledge and observed data.

The purpose of the study was to investigate the causal relations among attachment, and social support influencing problem behavior in middle school students. The data contains 482 middle school students. Collected data were analyzed using SPSS and AMOS statistical package for correlation analysis and structural equation modeling. Study results were as follows. The correlations among attachment, social support and problem behavior were significant. The results of the structural equation modeling show that students' social support had direct positive influence on problem behavior, but students' attachment didn't have direct positive influence on problem behavior. That is to say, social support mediated the effect of attachment on problem behavior. These results imply that perceived attachment, and social support influence adolescents' problem behavior. Results suggest that programs that promote social support should be given to reduce problem behaviors of middle school students.

Purpose: The purpose of this study was to identify factors affecting health promotion behavior among workers with high risk of metabolic syndrome. This study was based on the planned behavior theory. Methods: The participants were 167 workers at high risk of metabolic syndrome. Data were collected using a structured questionnaire. Surveyed variables were attitude, subjective norm, perceived behavioral control, intention, and health promotion behavior. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression analysis with SPSS/WIN 22.0. Results: Perceived behavioral control affected the intention of health promotion behavior among the workers with high risk of metabolic syndrome. It explained 62% of variance in the intention of health promotion behavior (F=40.09, p<.001). Perceived behavioral control and occupation affected health promotion behavior among the risk workers with high risk of metabolic syndrome. The two factors explained 16% of variance in health promotion behavior (F=4.95, p<.001). Conclusion: The findings of this study suggest that perceived behavioral control is the only factor affecting health promotion behavior when the theory of planned behavior was applied. Therefore, intervention programs for improving health promotion behavior should be focused on strengthening perceived behavioral control.
