Purpose: This study examined the dietary behavior and the effects of nutrition education according to the stages of behavioral changes in sodium reduction of healthy male adults (20~69 years) in Gwangju Chonnam Regions. Methods: The research subjects were 200 male adults. Results: A significantly higher mean age was observed in the stage of Action Maintenance (A M) than in the stage of Precontemplation (PC) and stage of Contemplation Preparation (C P). Significant differences in the frequency of exercise, eating out, and preference for salty food, intake frequency of Udon, Ramen and Sundae according to the stages of behavior change in sodium reduction were observed. The dietary behavior scores and intake frequency-related dietary behavior scores of A M were significantly higher than PC and C P. Nutrition education for sodium reduction improved the dietary behavior score significantly in PC and C P, as well as the rate of correct answers of sodium-related nutrition knowledge in all stages. After the nutrition education, PC decreased greatly, and A M increased. Conclusion: Subjects in PC and C P had an undesirable propensity in dietary behavior, and nutrition knowledge compared to A M, but the nutrition education for sodium reduction greatly improved their dietary behavior and nutrition knowledge.

The purpose of this study was to examine the relationship pattern among paternal parenting behaviors, father involvement, parenting stress, and parenting self- efficacy. The subjects were 299 fathers of 3 to 4 year-old children at 2 child care centers and 11 kindergartens in Seoul and the Gyunggi-do area. Fathers responded to a modified version of Parenting Daily Hassles(Crinc & Greeberg, 1990), a re vised version of Parenting Sense of Competence(Gibaud-Wallston & Wandersman, 1978), and questionnaires including questions about parenting behaviors(Park, 2000) and father involvement developed by authors. Stepwise regression analyses showed that fathers' cognitive efficacy of parenting and the frequency of play involvement on weekdays significantly explained paternal 'warmth encouragement'. Also, cognitive efficacy and the frequency and time amount of play involvement on weekdays significantly explained paternal 'setting up the limitations'. Meanwhile, fathers' emotional efficacy and the amount of play time involvement on weekdays significantly explained paternal 'over-protection permission'. Finally, the cognitive and emotional efficacy of rearing and parenting stress significantly explained paternal 'rejection non-intervention'.

The objective of this study is to investigate college student search behavior in an academic library. The theory of planned behavior was applied for identifying relationship among variables on search behavior. Data were collected in an university. For data analysis, ANOVA, factor analysis, regression analysis, cluster analysis were used. The result shows: the theory of planned behavior can be used for finding search intention in an academic library. Student major and library use frequency are different statistically in attitudes, perceived behavioral control, behavioral intention. Student characteristics are divided into four types: conservative, independent, friendship, fashion. Friendship type of students influences search behavior. From cluster analysis, the cluster included friendship and independent types of students and students who have high frequency of library use has more active intention for search in academic library.

The purpose of this study was to identify the participation in activities, emotions, and problem behaviors of elderly people residing in nursing homes. In this observational study targeting 81 elderly patients with dementia, each patient's participation in activities, emotion, and problem behaviors were observed for 4 hours per day with 20 minutes interval, which leads to 6,804 data based on 12 times a day for 7 days. According to this study, 90.1% of the participants were suffering from severe cognitive impairment. Their emotions were scored 4 out of 7. They mainly participated in activities such as sitting or lying down, which had no specific purpose, but they showed the most positive emotion when involved in social activities. The most frequent types of problem behaviors were repetitive behaviors and making noises, and the frequency of their behaviors were different depending on the time. There were significant correlation between cognitive functions, emotions, and problematic behaviors. Therefore, it is necessary to find effective ways to increase participation in activities, induce participation in positive emotional activities, and reduce problem behaviors manifested most prominently each hour of the elderly patients with dementia residing in nursing homes.

In this study, we analyzed verbal interactions among 32 students in 7th graders' science cooperative learning at the levels of turns, interaction units, and conflict behavior units, and compared their verbal interaction patterns between the heterogeneous and homogeneous groups by students' collectivism. The relationships of verbal interactions with the achievement test scores and the increase of the achievement test scores were also investigated. In the analyses of turns, the distributions of the subcategories of the statements related to the task were found to be similar in both groups, and the frequency of 'explain' was highest. The frequencies of interaction units were higher in the homogeneous groups than the heterogeneous groups, and the frequency of 'symmetric interaction' was highest. In the heterogeneous groups, the frequencies of turns and interaction units for the students of high collectivism were higher than those of low collectivism. The frequencies of conflict behavior units were generally low, but the rates were similar in both groups. In the case of the homogeneous groups, the frequencies of 'avoiding' and 'competing' for the students of low collectivism were high, and the frequency of 'cooperating' for the students of high collectivism was high. In addition, the qualitative differences between the two groups were found in the interaction units and conflict behavior units. The achievement test scores and the increase of the achievement test scores were positively related with the sum of the frequencies of the statements related to the task.

This study was examined the effective nonverbal behavior cues of detecting suspects' lies in the investigation scene. In order to search the suspects who drank the alcohol liquor without a permission, 18 soldiers were interviewed. 8 solders had drunken alcohol and had lied when was asked(lie group). The other 10 soldiers hadn't drunken alcohol and had told the truth(truth group). The mean frequencies of nonverbal behaviors were compared lie group with truth group. The following behaviors were measured by frequency: vocal characteristics (high pitch of voice, speech hesitations, speech error, frequency of pauses, period of pauses, latency period), facial characteristics (gaze, smile, touching face, blinking, facial micro-expression), body movement (illustrators, hand and finger movement, leg and foot movement, head movement, trunk movement, shifting position). As results, this study found that deception cues were periods and frequencies of pause, micro-expression, head movements. The lie group had less periods and frequencies of pause, and more micro-expression, head movements than truth group. But, this study didn't found Othello's error cues.

이상치는 주로 저빈도로 발생하기 때문에, 이상치 탐지 분야에서는 정상 데이터만을 이용한 비지도 기반 학습 모델을 사용하는 방법들이 제안되었다. 따라서, 본 논문에서는 반려동물 센서 데이터를 이용해 비지도 기반 모델인 DASVDD을 활용하여 이상치를 탐지한다. 하지만 데이터셋에 이상치가 존재하지 않아 반려동물이 고빈도로 보여주는 A행동군(서다, 앉다, 엎드리다, 눕다, 걷다), 저빈도로 보여주는 B행동군(킁킁대다, 먹다)으로 분리하여 학습을 진행한다. 모델의 성능은 ROC-AUC을 기준으로 79.05%의 성능을 보여주는 것을 확인하였다.
