Statistical differences between men and women are investigated for a total of eleven joint motions during level walking. Human locomotion which exhibits nonlinear dynamical behaviors is quantified by the chaos analysis. Time series of joint motions was obtained from gait experiments with ten young males and ten young females. Body motions were captured using eight video cameras, and the corresponding angular displacements of the neck and the upper body and lower extremity were computed by motion analysis software. The maximal Lyapunov exponents for eleven joints were calculated from attractors constructed and then were analyzed statistically by one-way ANOVA test to find any difference between the genders. This study shows that sexual differences in joint motions were statistically significant at the shoulder, knee and hip joints.

Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The "alone" classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

본 연구는 노인들의 보행 교통안전 환경을 개선하기 위한 정책제안을 목적으로 한다. 어린이 교통사고를 비롯하여 전체적으로 우리나라의 교통사고는 감소추세에 있지만 아직도 노인교통사고는 줄지 않고 있기 때문에 앞으로 급속히 진행되는 고령화 사회에 대응하기 위해서 노인 보행교통사고 저감대책 마련이 시급하다. 본 연구에서는 도로교통공단에서 제공한 최근 보행관련 교통사고를 유형별로 분석하여 노인 보행교통사고의 특성을 이해하고, 추가적으로 노인들을 대상으로 설문조사를 실시하여 보행안전을 위협하는 요인과 개선대책을 파악하였다. 연령대별 차대사람 교통사고 자료 분석결과 노인교통사고는 횡단보도나 교차로보다는 횡단보도 부근, 교차로 부근에서 사고가 많이 발생하고 있으며 보행자 과실 사고는 감소추세인 반면 운전자 과실로 인한 사고는 오히려 증가추세에 있음을 알 수 있다. 또한 연령대별 교통사고 발생비율을 살펴보면 ;U'자형 분포를 보이고 있어 향후 교통안전개선지점의 우선순위는 12세 이하의 어린이와 65세 이상의 노인연령대의 교통사고 잦은 지점을 통합한 기준을 고려할 필요가 있다. 설문조사를 통하여 파악된 내용으로써는 노인들은 도로교통 안내 표지판을 식별하는데 어려움이 있으며 많은 노인들이 교통정보내용을 이해하지 못하고 있는 것으로 나타났다. 또한 노인들이 교통안전상 불안을 느끼는 때는 교차로 횡단 시와 이면도로 보행시로 나타났으며 교통안전을 가장 위협하는 대상은 보도를 주행하는 오토바이와 보도에 불법 주차된 차량이라고 응답하였다. 교통사고자료와 설문조사의 결과를 토대로 교차로 및 횡단보도의 시설개선이 시급하며, 운전자를 대상으로 노인 보행특성에 대한 교육의 필요, 노인을 위한 휴게시설의 확충, 보도의 자전거도로 공유 금지, 보행교통사고지도 작성 등이 대책으로 제시되었다.

본 논문은 V2P(Vehicle to Pedestrian) 통신시스템에서 고령자의 보행 행태를 고려한 위험정보의 제공방법에 관한 연구이다. 본 연구에서는 경기도 지역의 2011년-2014년의 1219건의 노인교통사고에 대하여 도로유형(단일로, 교차로), 신호유무(무신호, 신호), 횡단보도유무(횡단보도, 무단횡단), 사고원인(무단횡단, 신호위반, 부주의사고, 기타)로 분류하여 고령자 사고의 행태를 분석하였다. 또한, 고령자의 행태변수와 차량속도변수를 검토하고, 기준치를 이용하여 상충위험정보제공에 활용하도록 하였다. 고령자의 보행속도, 안전여유값 그리고 차량의 접근속도에 따라 사고를 방지할 수 있도록 요구하는 거리를 제안한다. 본 연구의 결과물을 고령자 보행형태의 변수를 고려한 V2P 통신 및 P2V 통신 기반의 상충위험정보 제공시스템에 적용함으로써 고령자의 사고경감에 도움이 될 것으로 사료된다.

Recently, various researches in respect of the positioning technologies using satellites and the other sensors have made location-based services (LBS) more common and accurate. Consequently, concern about position information has been increasing. However, since these positioning systems only focus on user's position, it is difficult to know the user's attitude or detailed behaviors at the specific position. It is worthy to study on how to acquire such human attitude or behavior, because those information is useful to know the context of the user. In this paper, the sensor unit consisting of three dimensional accelerometer was attached to human body, and autonomously measured the perpendicular acceleration of ordinary human behaviors including activity modes such as walking, running, and transportation mode using transportation such as a train, a bus, and an elevator. Subsequently, using the classified measurement results, the method to identify the human activity modes was proposed.

The purposes of this study were to identify the dimensions of consumers' dissatisfaction with dress shoes when purchase and while using them, and to examine the differences in dissatisfaction factors among consumers grouped by age, occupation and purchasing characteristics. A questionnaire consisted of 86 consumer's dissatisfaction statements with purchasing and using women's dress shoes was developed after conducting 3 pilot tests, and administered to 5BO women in age between 20 and 60 years residing in Seoul and the metropolitan areas in June, 1997, 457 were used for data analysis. Ten factors of dissatisfaction with the women's dress shoes when buying them were identified: attitudes of salespersons, bargain sales, variety of styles, store environment, inconvenience in using girt certificates, fashion. advertisement, display, design, and size. During purchase stage, consumers grouped by demographic characteristics and purchase behaviors showed significant differences in design, attitudes of salespersons, store environment, and selected dissatisfaction factors. Nine dissatisfaction factors with using dress shoes were identified: physical discomfort, after-service, distort of shape, low quality, surface defects, suede/ wearing out, fit, inferiority of color and texture/walking discomforts. During consumption stage, consumers with different demographic characteristics and purchase behaviors were found significantly different in physical discomfort, fit, and selected dissatisfaction factors.

Objectives: The aim of this study was to confirm health behaviors that affect periodontal health status. Based on these results, we also intended to provide information for the prevention of gingivitis prior to periodontitis and establish strategies for maintaining healthy periodontal tissues. Methods: Data for this descriptive study were extracted from the Korea National Health and Nutrition Examination Survey 2013-2015. A total of 2,710 adults, aged 19-39 years were included in this study. Complex logistic regression analyses were performed to confirm relationships between health behaviors and periodontal health, after adjusting for socio-demographics, oral and systemic health status. Results: Dental clinic visits (odd ratio [OR] = 1.761, 95% confidence interval [CI]; 1.391-2.229), use of floss (OR = 1.504, 95% CI; 1.213-1.865), and non-smoking (OR = 1.269, 95% CI; 1.040-1.549) were found to support periodontal health. Conclusions: Dental visits for continued professional oral health care, self-oral care including interdental flossing, and a non-smoking habit, are necessary for periodontal health maintenance. Additionally, the results suggest that physical activities such as regular walking can help. These methods should be considered as the primary preventative care strategies for minimizing the occurrence of gingival inflammation.

To design senior housing that support residents' health is one of the comtemporary issues in Korea. As elderly people became more healthful and reach, people became interested in the health and health promotion. This trend encouraged this research study. The objectives of this study are: to analyze the middle aged people's opinions and behaviors related to health issues, and to suggest design considerations for senior housing. The survey used questionnaire from 476 residents living in Seoul and Gyeong-Gi area. The analysis used descriptive statistics, one-way anova and t-test. Primary findings are as follows: (1) Most of the respondents considered that their health state is 'good' and mental health is more important than physical health. (2) Many people exercise regularly for the promotion of health at a gym. (3) Results show that social relationship effect on health, and dietary life and walking medical examination account highly. (4) As the respondents are higher income and education level, the health-related behavior is more actively. Moreover the respondents who are women feel a great interest about health issues. These results suggest directions for planning of the senior housing. (1) Planning the space for the health-promoting behavior in the house or support a private gym-not a local facilities-. (2) Service for the information related health issues - medical examination, news of the health issues (3) Support the maintenance a good - social relationship (4) Consideration the space with health-related behavior like walking and dietary-life. The senior housing can reflect the health-related opinions and support health-related behavior of the elderly people.
