The purpose of this study was to investigate levels of dementia knowledge, dementia attitude, and physical activities and whether dementia knowledge and dementia attitude affect physical activities in old-old elderly who had high risk of dementia. A descriptive study design was used. Participants were 218 old-old elderly above 75 years at 9 elderly welfare facilities in K county from June 1 to 30 in 2016. Collected data were analyzed by t-test, ANOVA, Pearson's correlation coefficient, hierarchical regression using SPSS WIN 18.0 program. The mean scores of dementia knowledge, dementia attitude, and physical activity of participants were low, there were positive correlations between dementia knowledge and dementia attitude (r=.380, p<.001), and physical activities (r=.211, p=.002), and between dementia attitude and physical activities (r=.380, p<.001). The significant predictors of physical activities were dementia attitude (${\beta}=.271$, p<.001), gender (${\beta}=.207$, p=.003) and education level (${\beta}=.184$, p=.023). These variables explained 28.8% of physical activities. In conclusion, we need to develop a customized multifactorial physical activity program with considering dementia knowledge and dementia attitude especially for old-old elderly women with low education level.

전통적으로 바이오인식기술은 출입국심사, 출입통제 행정, 사회복지, 의료, 금융 등 다방면에서 폭넓게 보급되어 실생활에서 널리 활용되고 있다. 최근 들어, 모바일 지급결제서비스 ATM 인출기 인터넷전문은행 등과 같은 핀테크 분야에서 비대면 인증기술로 바이오인식기술이 각광을 받기 시작했다. 그러나 지문 얼굴 홍채 정맥 등 기존의 신체적 특징을 이용한 바이오인식기술은 가짜지문 등 신체적 특징을 이용한 바이오인식기술의 위변조 위협에 대한 우려가 존재하여 심전도 등 생체신호, 걸음걸이와 같이 살아있는 사람의 행동학적 특징을 이용한 차세대 바이오인식기술에 박차를 가하고 있는 추세이다. 이에 본 논문에서는 바이오인식 표준화를 위한 ITU-T SG17 Q9 국제표준화기구를 소개하고, X.tab 국제표준화 현황에 대하여 집중적으로 살펴보고자 한다.

기존의 생체인식 기술들은 노화에 따른 신체부위의 변형으로 인해 인식률 저하를 초래할 수 있으며 인식단계 시 눈과 같은 신체의 민감한 부분을 빛에 노출시키는 등의 불쾌감을 이용자에게 초래할 수 있다. 본 논문에서는 기존 생체인식 시스템이 갖는 이러한 문제들을 보완하기 위해 손가락 정맥영상을 이용한 생체인식 시스템을 제안한다. 손가락 정맥의 경우 인식 절차가 단순하면서도 개인마다 고유한 특징을 충분히 포함하고 있다. 또한 인체 내부에 존재하는 특징으로 인해 외상이나 노화로 인한 변형의 가능성이 적으며 촬영 시 이용자의 거부감이나 불쾌감을 최소화 할 수 있다.

현재의 언어자동인식은 목소리의 음성 정보와 얼굴영상의 화상정보를 병행처리하여 초기의 음성 정보만을 처리한 경우보다 높은 인식률을 가져왔다. 이러한 연구는 언어의 인식에서 뿐만 아니라, 신체가 부자연스러운 장애니에게는 간단한 의미 전달의 수단이나 각종 재활보조기기의 제어 등에도 매우 유용하게 활용될 수 있다. 음성정보처리를 배제한 영상정보처리 면에서, 본 논문의 대상이 되는 장애인은 신체의 부자연스러움으로 인해 처리되는 얼굴의 영상이 정상인과 같은 바른 자세가 되지 못하고, 기울어진다든지 틀어져서 기존의 방법들로는 정상인보다 현저히 낮은 입모양의 인식률을 보인다. 본 논문에서는 기존의 방법들과는 달리 청색 표식을 이용한 색상불할법과 라벨링을 통해 입 모양을 인식하는 방법을 제안하였으며, 이는 장애인과 같은 기울어진 얼굴영상에 대해서도 정상인과 같은 입 모양 인식률을 나타내었다.

The purpose of this study was to examine relationships among BMI, perception of body shape, appearance stress, and self-perceived competence on body image and to identify the factors that influence on body image in the adolescents. The data were collected from 140 adolescents in the three middle school located J city using self-reported questionnaires and March 15 2017 to March 29 2017. The data were analyzed by descriptive statistics, T-test, ANOVA, Pearson's correlation coefficient, and multiple regression with SPSS Statistics 20.0 program. Body image was found to be in a significant positive correlation with perception of body shape, appearance stress, and self-perceived competence. The result of the multiple regression indicates the self-perceived competence and gender predict 21%(F=10.25, p<.001) of body image. Therefore it is necessary to develop convergence self-perceived competence strategy program for establish right body image of adolescents.

In this paper, we describe interactive contents which is used the result of the inputted interface recognizing vision-based body gesture. Because the content uses the imp which is the common culture as the subject in Asia, we can enjoy it with culture familiarity. And also since the player can use their own gesture to fight with the imp in the game, they are naturally absorbed in the game. And the users can choose the multiple endings of the contents in the end of the scenario. In the part of the gesture recognition, KINECT is used to obtain the three-dimensional coordinates of each joint of the limb to capture the static pose of the actions. The vision-based 3D human pose recognition technology is used to method for convey human gesture in HCI(Human-Computer Interaction). 2D pose model based recognition method recognizes simple 2D human pose in particular environment On the other hand, 3D pose model which describes 3D human body skeletal structure can recognize more complex 3D pose than 2D pose model in because it can use joint angle and shape information of body part Because gestures can be presented through sequential static poses, we recognize the gestures which are configured poses by using HMM In this paper, we describe the interactive content which is used as input interface by using gesture recognition result. So, we can control the contents using only user's gestures naturally. And we intended to improve the immersion and the interest by using the imp who is used real-time interaction with user.

The purpose of this study was to examine the effects of perception of body size on actual clothing style in middle school girls. To achieve this, this study analyzed self-perception of body size, aspired clothing style, and actual clothing style. By classifying groups into thin and thick, the difference in clothing style according to groups was also analyzed. Subjects of this study were middle school girls in Gwangju and 219 responses were collected from real body measurement and questionnaires. WIN SPSS+10.0 package was used to obtain results. Results are as follows: 1. For the self-perception of body size, middle school girls perceived much thicker in the lower body than the upper body. And they were unsatisfactory about the lower body which was perceived thick. 2. In the correlation of actual and aspired clothing style of middle school girls, they wore a aspired clothing style actually. Their actual or aspired upper clothing style was to cover the skin, exposing or covering a body silhouette. Their lower clothing style was a slacks type that covers a body silhouette and the skin. 3. In selecting actual clothing styles, middle school girls were somewhat affected by self-perceived body size. But they did not prefer the clothing styles perceived thick in girth or big in width in exposing the skin or a body silhouette. On the other hand, as it was perceived long, wearing was increased. frequently wore the upper and lower clothing styles of exposing the skin or a body silhouette than the thick group. But both groups wore the clothing styles of covering the skin or a body silhouette regardless of their thinness and thickness. And when wearing the clothing style of exposing neck and shoulder, middle school girls considered actual body size more than self-perceived size. On the other hand, when wearing the clothing style of exposing arms and silhouette by fitted legs, they considered self-perceived body size more.

Purpose: The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. Methods: Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017-2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. Results: The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B₁, niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents' physical activity increased. Conclusion: The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.

This study first examines the effect of perceived body characteristics, satisfaction with body characteristics on perceived size related risk, and internet shopping clothing behaviors; in addition, it also examines the effect of the perceived size related risk on clothing behaviors. A questionnaire was conducted with responses from 219 female students, aged 19 to 25. Data was analyzed by frequency analysis, correlation analysis, ANOVA and Duncan test. The findings suggest that a consumer satisfied with body characteristics has active clothing behaviors to improve her appearance or body image. The effects of perceived body characteristics and satisfaction with body characteristics on perceived size related risk are also identified. The perceived size related risk increases when the size information of an internet shopping mall is insufficient compared to the situation when the consumer is not satisfied with her body characteristics. The meaningful differences of clothing behaviors according to extent of perceived size related risk are identified.
