Changes in a person's health affect one's lifestyle and work activities. According to the World Health Organization (WHO), abnormal activity is growing faster in people aged 60 or more than any other age group in almost every country. This trend steadily continues and expected to increase further in the near future. Abnormal activity put these people at high risk of expected incidents since most of these people live alone. Human abnormal activity analysis is a challenging, useful and interesting problem among the researchers and its particularly crucial task in life and health care areas. In this paper, we discuss the problem of abnormal activities of old people lives alone at home. We propose Convolutional Neural Network (CNN) based model to detect the abnormal behaviors of elderlies by utilizing six simulated action data from daily life actions.

To understand the multilateral characteristics of human behavior and physiological markers related to physical, emotional, and environmental states, extensive lifelog data collection in a real-world environment is essential. Here, we propose a data collection method using multimodal mobile sensing and present a long-term dataset from 22 subjects and 616 days of experimental sessions. The dataset contains over 10 000 hours of data, including physiological, data such as photoplethysmography, electrodermal activity, and skin temperature in addition to the multivariate behavioral data. Furthermore, it consists of 10 372 user labels with emotional states and 590 days of sleep quality data. To demonstrate feasibility, human activity recognition was applied on the sensor data using a convolutional neural network-based deep learning model with 92.78% recognition accuracy. From the activity recognition result, we extracted the daily behavior pattern and discovered five representative models by applying spectral clustering. This demonstrates that the dataset contributed toward understanding human behavior using multimodal data accumulated throughout daily lives under natural conditions.

The purpose of this study is to grasp the relationship between the amount of physical activities at work perceived by workers and their health promotion behaviors. To achieve such a purpose. this survey was conducted on 476 Workers who work for 3 food product work-sites located in Keong-in area by means of questionnaire from June 15 to July 14 . 1998. Collected data were statistically analyzed by SPSS/WlN. The significant results were obtained as follows. 1. The average scores of the amount of physical activities at work and health promotion behavior were 3.18 and 2.84 respectively; the former was slightly higher than moderate score 2.5 and the latter was almost the same as it. It can be interpreted that workers perceive their physical activities at work are heavier than their daily activities, which seems to make their health promotion behaviors still inactivated. 2. The amount of physical activities at work, it was were greater revealed that the more activities workers do after work. the more they walk and the more exercises they do. It implies that the voluntary practice of good health habit at leisure can be greatly contributed to the activation of more productive activity at work. 3. The amount of health promotion behaviors was larger as workers do more physical activities at work and have lower PIBW(Percent Ideal Body Weight). It means that the voluntary practice of good health habit is closely related to the degree of obesity and their positive attitude toward their work. Average PIBW was 106.71; most of the workers are distributed within the standard range in their weight. So we can presume that most of them are not seriously conscious of weight maintenance in their daily lives. Therefore it is desirable that health promotion program for workers should be developed toward connecting their physical activities at work with those in their daily lives much more. Physical activities, health promotion behaviors

Purpose: The aim of this study was to develop a substantive theory on self-management conducted by the adolescents with chronic kidney disease from their lived experience. Methods: Data was collected through in-depth interviews from May to December in 2015 with thirteen adolescents with chronic kidney disease. The data collected were analyzed on the basis of Strauss and Corbin's grounded theory. Results: The core of the category found in this study was "overcoming the unstable sense of self- control and integrating disease experience into their life". The causal conditions triggering the central phenomenon were "restriction in daily life" and "manifestation and aggravation of symptom". The central phenomenon in the experience of self-management within the adolescents with chronic kidney disease was "unstable sense of self control". The intervening condition for unstable self control were "micro system support" and "motivational resources". This study found that the adolescents with chronic kidney disease followed a series of strategies when they faced the central phenomenon, including; passive coping, reappraisal of illness, active coping, compliance with treatment, controlling physical activity, and adjusting school life. With these strategic approaches, the adolescents with chronic kidney disease could maintain their active lifestyles and achieve their health behaviors. The process of self-management by these adolescents passed through four phases; limited experience caused by diseases, effort for normalization, reorganizing their daily lives, and integration with daily lives and self-management. Conclusion: This Study explored the process and experience of self-management of adolescents with chronic kidney disease. These findings can be used for basis for developing substantive theory and nursing intervention strategy for adolescents with chronic kidney diseases.

This study examined young Korean children's perceptions about scientists, kindergarten science and the application of science in their daily lives. An interview questionnaire developed by the researchers and based on Chamber (1983)'s Draw-A-Scientist Test (DAST), was administered to 104 five-year-old children. Most of the children (68.2%) saw themselves doing activity-oriented science in kindergarten, but they did not use outside kindergarten for the knowledge and skills they learn in science (70.4%). In general, children recognized scientist as a male working with lab equipment in the laboratory. Although most of children (74.5%) were interested in science, only a few of them (12.5%) hoped to be a scientist in the future. There were significant differences attributable to gender in preference for science; girls showed more interest in science than boys.

This study purports to examine sociodemographic characteristics and those factors associated with osteoarthritis in women experiencing the disease in order to make suggestions for the prevention and management of osteoarthritis in women. The subjects were 143 women who were diagnosed to have osteoarthritis and under follow-up care at an outpatient department of a university-affiliated hospital. The data were collected through personal interviews by using the structured questionnaire between October 6 and October 24, 1997. The degree of daily living activities was measured with 24 items, which were made based upon Katz Index, Barthel Index and Functional Status Index. Each item has 4 response categories : (1) being able to do alone with any difficulty, (2) being able to do alone with some difficulty, (3) being able to do alone with the help of a person or an instrument, (4) not being able to do at all. The data was analyzed with correlation analysis, t-test, ANOVA, and regression analysis. The results are summarized as follows : 1. As for the age of the subjects, 59.4% were between 45 and 64 years, while 28% were 65 years and above. The subjects having religion were 71.7% and 44.1% of the subjects were protestants. The educational level was low : 31.5% graduated from elementary school, while 30.1% had no formal education. Those married subjects were 72%. Fifty nine percent of the subjects evaluated their economic status as middle class. 2. Those people from whom the subjects currently receive some help were spouses in 35.8% of the subjects. Likewise, 50% of the subjects indicated spouse as the people from whom they want to receive help. 3. The score of the ability of daily living activities ranged between 48 and 96, with the mean of 78.94. Those means of physical activity, ADL(activities of daily living) and IADL(instrumental activities of daily living) were 14.89, 13.97 and 50.09, respectively. Except for the items of carrying heavy stuff and of washing clothes in the sitting position the subjects showed independence in more than 90% of the items, where Independence is defined as being able to do alone or with the help of a person or an instrument. 4. The increase in age was a significant predictor of the decrease in the ability of daily living activities. Those graduated from middle school and above showed a significantly higher degree in the ability of daily living activities than those with less educational level. The married women revealed significantly higher scores in physical activity, ADL, and IADL than the unmarried ones. The ability of daily living activities was not significantly related to having religion, economic status and living with family. 5. The average duration of experiencing osteoarthritis was 4 years and 7 months. Regarding the site of the onset, 65% of the subjects indicated knees. The women with osteoarthritis for less than 3 years were 65%. The ability of daily living activities was significantly different by the duration of illness : the longer the duration of illness, the less the ability of activities. The above findings suggest the need for developing those programs for prevention disabilities in performing daily living activities and for managing diseases targeting the women of middle and old age, with low educational level, and with unmarried status. In addition, there should be developed an instrument for measuring the ability of daily living activities which reflects daily lives of Korean women with osteoarthritis in order to examine comprehensive effects of osteoarthritis on women's daily lives in this country.

Objectives : To analyze factors associated with elderly falls in a community dwelling, a comparatively important, but somewhat neglected, health mailer. Methods : Data came from personal interview surveys using a questionnaire of 552 people aged 65 or older living in a community. Socioeconomic, and health related characteristics were investigated as independent variables and experiences of falling in the previous year as the dependent variable. Results : 118(21.4%) of the elderly subjects experienced a fall in the previous year. 24 subjects experienced more than two falls, accounting for 20.3% of the elderly fall victims studied. Factors affecting the falls were families living together, level of daily activity, heart disease, and aconuresis;, therefore an elderly person who lives alone, lives independently, has heart disease, or suffers urinary incontinence had a demonstrated increased chance of failing. Conclusion : Groups at risk for luting included elderly persons living alone, living independently, suffering heart disease, or experiencing urinary incontinence. When an elderly fall prevention program is developed and implemented, these results should be considered.

Background: The purpose of this study is to determine how the cognitive state of the elderly influences the activities of daily living(ADL) in order to increase their achievement capacity and their ability to exercise this capacity in daily life. The MMSE-K(Mini-Mental State Examination-Korean) was used to evaluate the daily activities and cognitive state of a group of subjects more than 65 years of age. The goal was to understand (1) How their achievement level in their daily activities changes according to the increase and decrease of their cognition points by analyzing and comparing their achievement points in the mental state examination, and (2) What variables influence that daily achievement level. Methods: The survey was conducted by a group of students from AnSan College who were trained for this method of data collection. The group surveyed 224 senior citizens older than 65 to determine their ADL performance. The subjects were selected from Silver Care Centers in the Gyounggi Province area including centers in Suwon, Anyang, Kwachun, and Sanbon City. The subjects were given enough information to fully understand the purpose of the study and the method by which it would be conducted. The survey method was a direct interview: which involved an interviewer reading the questionnaire to the subject and recording the answer. Result: The following results were calculated using SPSS WIN ver. 13.0: In the lower score of the MMSE-K regarding ADL performance (K-MBI) for activities such as individual hygiene, bathing activity, food activity, toilet management, going up stairs, getting dressed ad undressed, controlling stools and urination, walking, and chair/bed movement, most of the subjects responded that they could not perform these activities by themselves (p<.01). In the higher scores for the same activities, most response that they could perform the tasks by themselves (p<.01). In the results of the multiple regression analysis, there influence of the variables for ADL performance (K-MBI) and MMSE-K score was higher for females than males. Conclusion: This study evaluated the cognitive state of the elderly using the MMSE-K, which is the most convenient method, and examined how the cognitive state influences the achievement capacity of the daily lives with other variables. In conclusion, the higher the score on the MMSE-K, the more independent the elders are in the activities of daily living, especially among women more than men.

The purpose of this study was to investigate the prevalence, relative factor and the effects that overactive bladder or urinary incontinence have on women's lives. Data was gathered through an internet survey. The subjects included 3,372 women ranging from 20 years old to 49 years of age. The questionnaire included general characteristics (age, parity, family history, and history of UTI), overactive bladder symptoms (urgency, frequency, nocturia, urgent incontinence), urinary incontinence, discomfort in ADL and sexual activity. The data was analyzed by the SPSS/PC+ program using frequency, $x^2$ test, and multivariate logistic regression. The results were as follows; 1. The prevalence was 12.7 % in overactive bladder and 21.0% in urinary incontinence. 2. 19.2% of the subject have urge incontinence, 5% of them have coped with the use of a pad. 3. The significant factors to overactive bladder were age($x^2$=6.6, p<0.05), history of urinary tract infection ($x^2$=50.8, p<0.01) and family history ($x^2$=26.1, p<0.01). The significant factors to urinary incontinence were age ($x^2$=6.2, p<0.05), occupation ($x^2$=11.0, p<0.05), history of urinary tract infection($x^2$=20.2, p<0.01), parity ($x^2$=8.6, p<0.01), and family history ($x^2$=4.9, p<0.05). 4. Overactive bladder impacts on individual daily life was 5.0 times, urinary incontinence was 2.9 times higher than in non-symptoms. Also, overactive bladder impacts on their sexual activity disturbance was 4.3 times, urinary incontinence has 3.9 times higher than in non-symptoms. In conclusion, overactive bladder symptoms and urinary incontinence were health problems that disturbed women's lives. Also the most problem among overactive bladder may be urgency in Korean. Intervention based on these results needs to be provided for these women.
