Development of various sensors attached to mobile and wearable devices has led to increasing recognition of current context-based service to the user. In this study, we proposed a probabilistic model for recognizing user's food intake context, which can occur in a great variety of contexts. The model uses low-level sensor data from mobile and wrist-wearable devices that can be widely available in daily life. To cope with innate complexity and fuzziness in high-level activities like food intake, a context model represents the relevant contexts systematically based on 4 components of activity theory and 5 W's, and tree-structured Bayesian network recognizes the probabilistic state. To verify the proposed method, we collected 383 minutes of data from 4 people in a week and found that the proposed method outperforms the conventional machine learning methods in accuracy (93.21%). Also, we conducted a scenario-based test and investigated the effect contribution of individual components for recognition.

This study examined the nursing student's preliminary knowledge and awareness of patient's personal information protection. 187 respondents, who were trained in 2 different nursing colleges in Kyungpook province, participated in the survey from May 18 to June 12, 2015. Using the data collected, descriptive statistics, T-test and one-way ANOVA were implemented. As a result, the student nurses, who had heard about the Personal Information Protection Act showed a significantly higher awareness score of patient's personal information protection behavior than those who did not. The respondents educated in personal information protection were reported to have a higher score of awareness about the patient's personal information protection behavior. In this regard, it is vital for university organizers to develop education associated with ethics and information security, which could enhance the perceptions of personal information protection for student nurses before their working career begins.

The purpose of this study is to analysis of the difference between dementia policy perception, dementia knowledge, dementia attitude and dementia prevention behavior of middle-aged. The subjects were 217 middle-aged in their 40 to 64 years old who lived in D and G cities. The mean sore of were dementia policy perception 75.42±8.52, dementia knowledge 8.71±1.90, dementia attitude 28.55±5.10, dementia prevention behavior 27.04±3.35. Dementia knowledge were significant differences in gender, number of diseases, source of dementia information. Dementia attitudes were significant differences in gender, age, education, dementia in family, dementia living together, job status, early examination, source of dementia information. Dementia prevention behavior were significant difference in dementia living together and early examination. The most category of dementia prevention behavior was 'cigarette smoking(Inverse question)', and blood pressure and diabetes management' were the lowest. Therefore, development of a professional and systematic dementia education program to raise the awareness of dementia policy among middle-aged adults and form the right dementia knowledge and positive dementia attitude. Development of customized dementia prevention behavior programs to maintain cognitive activities, social activities, proper eating habits, and health care is needed.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level. Therefore, the education for oral health behavior is required to improve oral health and studies are needed to present the development of program for awareness and knowledge of oral health affecting behavior.

This study was conducted to investigate the effects of oral health awareness and oral health behavior on cardiocerebrovascular prevention behavior in a cardiocerebrovascular diseases risk group and provide basic data for a nursing intervention program for the group. Data were collected from 131 people in the risk group of cardiocerebrovascular diseases living in J Province in February and March of 2018. The obtained data were analyzed using descriptive statistics, t-tests, Pearson's correlation, and stepwise multiple regression analysis. The results revealed that preventive acts were positively correlated with subjective oral health state (r=0.261, p=0.003), importance of oral health (r=0.250, p=0.004), and practice of oral health (r=0.303, p<0.001). Moreover, acts to prevent cardiocerebrovascular disease were influenced by oral health (${\beta}=0.29$, p<0.001), age (${\beta}=0.27$, p=0.001), and subjective oral health state (${\beta}=0.24$, p=0.003). Specifically, scores of preventive acts for cardiocerebrovascular diseases increased with higher degree of oral health behavior, older age, and better subjective oral health state. These variables had an explanatory power of 19.3%. The results of this study imply a need to prepare measures to enhance the oral health level of the risk group of cardiocerebrovascular diseases and conduct ongoing follow-up studies of the perception, attitude, and behavior of individuals toward oral health, as well as the state of oral health.

인류 문명은 철학, 사상, 과학, 기술의 발달에 의해 진화되어 왔으며 그 근저에는 개념의 생성이라는 창조 행위가 있었다. 이것은 하나의 상징 행위라 할 수 있으며 인간과 동물을 구분짓는 행위라 할 수 있다. 그렇다면 이런 행위들은 어떻게 가능한 것인가? 본 논문은 이러한 창조행위의 근거를 영성에 의한 영감의 발현이라 전제하며 이를 바탕으로 한 문화의 개념인 SeaCircle을 통해 창조적 문화 실현을 위한 인식의 확대를 꾀하고자 한다.

현대 사회에서 테러는 국제적으로 매우 빈번하게 일어나고 있으며, 대한민국도 더 이상 테러의 안전지대가 아니라는 뉴스가 보도되고 있다. 하지만 우리에 테러의 인식에 따른 시각은 다소 편협하여 성별, 나이, 직위, 장소등 많은 부분에서 갈등을 갖으며, 또한 한반도는 남북한의 갈등으로 인한 특수성은 게릴라 전을 테러라고 인식하는 시각이 있다. 국내 특수성으로 인해 테러를 전쟁의 영역으로 보고 테러대응 전략은 국가 안보로 많이 치우쳐져 있다. 역사와 정치적으로 또한 테러는 이념대립으로 인한 전쟁으로 치우쳐 전쟁의 전략에 한 부분으로 인식 되어 왔다는 것이 사실이다.(Rumyana G., 2014) 이는 전쟁의 시각에서 테러를 잘 설명하고 있다. 한편, 테러의 개념은 시간이 지남에 따라 기존의 안보의 개념뿐 아니라 재난의 개념에서도 찾을 수 있다. "불평등한 사회에 대한 민중의 분노로 이해하여야 한다"고 스위스 진보적 사회학자 장 징글러(Jean Ziegler) 는 말하며 무고한 사람들을 타겟으로 한 정치적 목적을 이루기 위한 비합법적 무력 사용으로 보았다. 즉, 비합법적 무력사용으로 무고한 다중(Innocent people)에게 폭력을 행사한 것이다. 젠킨스와 라쿼르의 정의를 살펴보면 "테러리즘이란 폭력 혹은 폭력의 위협이다"라고 정하였다.(Jenkins 2004) 폭력이란 형법에서는 다른 사람에게 상해를 입히거나 협박하거나 하는 등의 행위와 함께 다른 사람을 감금하는 행위, 주거에 침입하는 행위, 기물의 파손 등에 대해서도 폭력이라 표현한다. 철학, 정치학 등의 학문에서는 다른 사람 또는 국가나 세력을 제압하는 힘을 일반적으로 지칭하기도 한다. 힘자랑이나 힘겨루기가 이에 속한다. 무력의 사용으로 사회에 심리적인 영향을 끼치며 사회적 파괴를 일으키는 것을 보편적 테러의 개념으로 볼 수 있다. 테러는 국가 통치 질서와 사회질서 안정에 큰 위협과 혼란을 초래하는 파괴행위의 무력행사로 국가의 재난 상황을 유발하는 인류가 만든 재난으로 볼 수 있다. 자연현상으로 발생하는 자연재해는 인류의 시점에서 재난으로 해석된다. 마찬가지로 사회현상으로 발생하는 폭력적 파괴행위에 대한 피해는 인류의 시점에서 재난의 현상으로 해석 되어야 한다. 과학기술이 발달하면서 첨단기술을 이용한 폭력행위와 파괴의 두려움은 정보통신 기술의 발달로 두려움의 전파 속도도 빨라 질 것이다. 따라서 테러행위의 극복을 위해서는 테러를 인적재난(Man-made Disaster)로 보고 재난의 범주로 포함하여 미래의 테러를 위한 대비전략을 수립해야 할 것이다. 이를 위해 본 논문에서는 학계의 학자들과 기관 및 민간 의 전문기관들에 따른 테러의 정의를 분석하고 재난정의를 고찰하여 시사점을 제시하고, 대테러 대비 전략의 방향에 기틀을 마련하고자 테러정의를 도출하였습니다.

Despite anti-corruption has been one of the major governmental tasks in Korea, anti-corruption policies have been focused largely on government officials in public sectors, and most of the prior studies have examined government employees not public citizens. In order to fill the vacuum in the literature, this study aims to develop evidence-based anti-corruption policies via a survey of people in various job categories for the relationship between their experiences of any corruption and related factors. Researchers analyzed a secondary data gathered by the Korean Institute of Public Administration, which included a sample of 1,000 adults aged over 19. The results showed that indirect experiences of corruption and interaction with the corrupted were positively related to individuals' corruption behaviors. In addition, their perception towards low- and mid-ranking officials were statistically signifiant in explaining the corruption behavior. Thus, policy-makers should consider focusing on indirect experiences of corruption, interaction with the corrupted, and perception towards low- and mid-ranking officials. This study contributed as an attempt to suggest policy implications and further research ideas by examining factors related to individuals' corruption behaviors.

The purpose of this study is to investigate the effect of leader-member exchange (LMX) on envy and counterproductive behaviors (CWB) moderated by similarity. Specifically, we focused on the negative side of LMX to examine the relationship between LMX and envy, and the mediating role of envy on the relationship between LMX and CWB. Further, we also examined the moderating role of similarity on the relationship between envy and CWB. Given that CWB can be harmful to any organizational, it was worthwhile to find possible antecedents of CWB, envy and LMX. A total number of 238 employees participated in this study and the results supported our hypotheses. The results of this study can have managerial implications, showing the important role of manager's personalized treatment for each of his/her subordinates.
