This study was analyzed obesity status by divided into six classification based on the body mass index(BMI) established by World Health Organization-Western Pacific Regional Office(WHO-WPRO) through National Health Insurance Service(NHIS). In the middle of process, problems of outlier solved by presenting the median repeated interpolation. Unlike linear and Lagrange interpolation, median repeated interpolation may be useful in multiple outlier contained dataset. As a result, we found that extreme low and obesity weight gradually increased and the frequency of normal body weight gradually decreased. Especially, the increase of obesity in men and women of lower age group is increasing. Overall, this study suggests that national measures need to be taken before health problems arising from obesity can spread to other social problems.

By increasing people's average life span, interest for health is highly growing. According to hoping to check their body condition, people have a medical checkup periodically to check their condition. But, they can prevent disease or are able to make a health care through checking people's pulse or blood pressure. In this paper, two different pulse measurement systems were developed, one system using a photosensor which is able to measure transmissivity's change through blood volume and another system using a piezo-electric sensor which can measure pulse when it measures radial artery's pressure in the wrist are realized. We compared two systems each other.

In this study, using a complex of physical, chemical, and biological evaluation factors, the ecological vulnerability to climate change were evaluated at each river in the Nakdong river basin. First, runoff, sediment rate, and low flow discharge changes according to AIB climate change scenario using the SWAT model were simulated. Also, for the assessment of chemical and biological factors, 48 points that water quality monitoring sites and ecological health measurement points are matched with each other was selected. The water quality data of BOD and T-P and the biological data of IBI and KSI in each point were reflected in the assessment. Also, the future rise in water temperature of the rivers in Nakdong river basin was predicted, and the impact of water temperature rise on the fish habitat was evaluated. The top 10 most vulnerable points was presented through a summary of each evaluation factor. This study has a contribution to river restoration or management plan according to the characteristics of each river.

This study was conducted to examine changes in coffee intake according to the sociodemographic characteristics of the people over 50 and the elderly living in Korea. The data of 2,316 and 3,170 people were extracted respectively from the 2001 and 2011 Korea National Health and Nutrition Examination Surveys. The data were analyzed by gender, age, region area, marital status, educational level, household income, economic activity, and subjective health status. They were also analyzed according to gender and age by average daily intake of coffee, coffee type, place, cups of coffee a day and amount of coffee intake per serving. All statistical analyses were performed with IBM PASW Statistics (SPSS) 21.0 which is capable of complex sample design by frequency analysis, chi-square test, t-test, and logistic regression analysis. The results of the study showed that coffee consumption of the elderly was influenced by their economic activity. In 2011, elderly men ingested averagely more coffee than elderly women, and they also consumed brewed coffee mostly at workplace. Moreover, age groups of over 75 tended to consume a lot of brewed coffee. In this respect, the coffee industry should be aware of the elderly as a new consumption group. Also, this study provides a variety of coffee shops with basic data for product development and marketing activities.

This research was conducted to see the correlation between changes of ankle Joint Position Sense and Sway Area through Unstable Surface training. For the study, 48 healthy males and females were randomly divided into an unstable surface group(n=24) and a stable surface group(n=24). Then, they were asked to carry out the same exercise program three times a week for six weeks. The unstable surface group and stable surface group performed the exercise program on the balance exercise pad and on the hard ground, respectively. As a result, the unstable surface group displayed significantly reduced error of ankle joint position sense and sway area(p<.05). Moreover, a significant correlation between variances of ankle joint position sense and sway area was only found in the unstable surface group. In conclusion, this study demonstrated that there was a significant correlation between changes of ankle joint position sense and sway area through proprioceptive sense training on the unstable surface.

Most elderly have difficulties in managing food safety and nutrition by themselves. Various nutrition educations for the elderly have been developed, but food safety and nutrition education program and educational tools for the elderly are very limited. The aim of the study was to evaluate a food safety and nutrition education program based on the Health Belief Model (HBM) for the elderly. Education program was implemented for 220 seniors (137 educated group and 83 control group) aged over 65 years at senior welfare community centers. The intervention study was carried out on a weekly basis during each of 5 weeks, and each session lasted about 35 or 40 minutes. The effectiveness of the program was assessed with a questionnaire before and after education. Education program consisted of a 5 week program, and topics were 'Dietary changes for the elderly's healthy life', 'Prevention of food poisoning in everyday life', 'Safe food handling for my health', 'Healthy dietary life to prevent chronic disease', and 'Safety! nutrition! healthy dietary life'. Education program materials such as slides, handouts, videos, leaflet, and booklets were developed. As a result, there were score improvements in knowledge, dietary behaviors, and health belief after intervention in the intervention group, which were higher than those of the control group. In particular, there was a meaningful interrelation between dietary behavior and health belief (r=0.520, P<0.001). This finding suggests that changing beliefs is very important to make desirable dietary behavioral changes. For this reason, we can conclude HBM theory is an effective model to educate nutrition and food safety for the elderly. Furthermore, food safety and nutrition education programs are implemented and delivered continuously at various settings such as a health center or community welfare center, and those will contribute significantly to enhance perception and change their desirable dietary behaviors for the elderly.

하상 변화는 유량이나 유사의 흐름에 따라 침식, 운반, 퇴적되어 변화하며, 하상변동에 의한 결과는 하천의 형태 (직렬,복렬, 곡렬 등)나 서식처의 구조 (여울과 소, 웅덩이, 습지 등) 형성 로 나타난다. 하천이 공간적 시간적 규모가 연계되어 있음에도, 국내에서의 하천 복원 사업은 서식처의 구조나 형태에 중점을 둔 서식처 조성 사업이 주를 이룬다. 하지만 궁극적인 생태하천 복원 및 관리를 위해서는 생태적인 서식처의 구조가 제대로 발현되는 유량이나 유사량과 연계하여, 통합 유역관리가 가능하도록 진행하여야 한다. 본 연구에서는 수리 (유량이나 유사량)-지형(서식처 구조)-생태 (생물다양성)을 연계하여 하천의 환경유량을 산정하는 방안을 제안하고자 한다. Nays2D 수리모델링을 활용하여 하상변화를 살펴보고, 수리모델링 결과를 서식처 구조 분포로 해석하여, 서식처가 다양한 유량을 산정하고 제안한다. 수리모델링 이전에 하천건강성 평가에 활용된 하천 생물종 모니터링 결과와 서식처 다양성과의 관계를 우선 분석하고 수리모델링을 진행한다. 본 연구의 대상 하천은 금강 지류인 갑천 약 5 km를 대상으로 2010년대 생물상, 항공사진, 지형데이타 (DEM and 단면도)를 활용한다.

서울시민의 인체건강을 보호하고, 쾌적한 생활환경을 조성하는 것은 도시공간상의 대기오염물질 발생량 저감 및 관리와 밀접한 관련을 맺고 있다. 그러나 서울시 대기환경 수준은 사회·경제적 여건변화와 교통, 토지이용, 에너지 소비 둥 여러 가지 영향인자의 복합적 작용의 결과이나, 이를 종합적으로 파악하고 대처하기 위한 처방은 다소 미흡한 수준이다. (중략)
