Research on gait recognition and its use is actively underway. This study suggests a method to recognize abnormal gaits of pedestrians. The purposes of the existing research to recognize normal steps are to measure physical activities and to validate people by their walks, but the purpose to recognize abnormal steps in this study is to insure the safe life of pedestrians. There are situations in which pedestrians are unaware of themselves vulnerable and can not ask for help. The purpose of this research is that even if pedestrians are unaware of themselves and there are no spontaneous requests for helps, it is intended for them to escape from dangers and difficulties by adopting the recent IOT technology. Hence, this study analyzes normal pace of pedestrians using the triaxial acceleration sensors, and takes ranges of their normal walking. And then, the steps of pedestrians are measured using the triaxial acceleration sensors, contrasted with their normal walking ranges, and determine whether their steps are normal or not. When it is out of the state for normal paces, a method to determine as abnormal paces is suggested.

The purpose of this study was to assess the physical activity of preschool children using an accelerometer and investigate differences related to epoch length setting during use of the accelerometer. Subjects of the study were 26 children (12 boys and 14 girls) at the age of 5, enrolled in one preschool located in Gangneung. From 9:00 a.m. to 4:00 p.m. (7 hours period), every child wore a total of four accelerometers (ActiGraph $GT3X^+$, USA), including three attached to the left hip (with epoch length set at 5 seconds, 15 seconds, and 30 seconds). For comparison purposes, a forth was attached to the opposite position, with epoch length set at 5 seconds. Data collected using 15s epoch and 30s epoch (single larger epoch) were compared with those obtained after reintegration of 5s to 15s epoch, 5s to 30s epoch, and 15s to 30s epoch, respectively (smaller epochs reintegrated). According to the results of this study, there were no significant differences in VM between 30s epoch and 5s to 30s epoch reintegrated and in MVPA (moderate-to-vigorous physical activity), between 15s epoch and 5s to 15s epoch reintegrated. From the Bland-Altman plot, reintegration of 15s to 30s epoch in VM and reintegrations of 15s to 30s epoch and 5s to 15s epoch in MVPA can be recommended for assessing physical activity in preschool children. Further research is needed into the reintegration method while using an accelerometer for assessment of energy expenditure in children.

This study was conducted to analyze the effects of smoking and drinking on quality of life in Adults. The content was analyzed for aged 30 years or older using data from the 7th National Health and Nutrition Survey(2017). The total number of subjects of this study was 5,465. Socio-demographic characteristics, health-related variables and EQ-5D index scores were used for the analysis. Statistical analysis was performed using the IBM SPSS ver.23 program. As a result of the analysis, there were statistically significant differences in smoking status, binge drinking, subjective health status and stress perception with quality of life. In the regression after adjusting the control variables, 'the amount of alcohol consumed at once(β=.106)' was statistically significant. However smoking status and binge drinking were not statistically significant. Therefore, it is necessary to develop Convergence drinking intervention program to improve the quality of life in adults.

The purpose of this study was to identify the influencing factors of Korean adolescents' consumption of convenience foods based on a bio-psycho-social model. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. As a result of the study, gender, grade, and atopic dermatitis were biological factors of convenience food intake in adolescents. The psychological factors were perceived stress level, experience of depression, suicidal ideation, subjective sleep sufficiency, perceived health status, physical activity, and current smoking and drinking. And nutrition and meal education, breakfast frequency, subjective academic achievement, subjective economic status, and family living together were sociological factors that affected adolescents' convenience food intake experience. Therefore, it is necessary to provide effective nutrition education programs and provide emotional support to manage healthy eating habits of adolescents. In addition, family members of adolescents should be included in education.

This study aims to clarify factors having effect on the turnover and entrepreneurial intention of financial institution workers. Particularly, this study analyzed the effect of job satisfaction, job insecurity, retirement expectation and retirement preparation activities. As research subjects, this study selected financial institution workers residing in Seoul and the capital area and used a total of 508 samples as analysis data. This study analyzed job satisfaction, job insecurity, retirement expectation and retirement preparation activities as factors having effect on the turnover and entrepreneurial intention of financial institution workers. The research results can be summarized as follows; Firstly, all the factors of job satisfaction had negative (-) effect on their turnover intention, and compensation satisfaction and interpersonal relation satisfaction also had negative (-) effect on their entrepreneurial intention. Secondly, since job insecurity had positive (+) effect on their turnover intention and entrepreneurial intentions, the more insecure their jobs became, the more their turnover and entrepreneurial intention increased. Thirdly, in the retirement expectation, forced frustration and continuation had positive (+) effect on their turnover intention, and forced frustration, new start and continuation also had positive (+) effect on their entrepreneurial intention. Fourthly, in the retirement preparation activity, entrepreneurial preparation, social preparation and physical preparation of retirement preparation activity had positive (+) effect on their turnover intention, but economical preparation had negative (-) effect on their turnover intention, while entrepreneurial preparation had positive (+) effect on their entrepreneurial intention. In other words, as they prepare business start-up more for retirement, their turnover and entrepreneurial intentions increase more. Although they receive higher wages than other workers in different job fields as financial institution workers, they showed significant results about turnover and entrepreneurial intentions, which indicates that job satisfaction, job insecurity, retirement expectation and preparation activities function as important variables in the relation with their turnover and entrepreneurial intentions. Such research results imply that it is necessary to develop various educational programs and turnover and business start-up support programs so that financial institution workers may have better understanding of both success and failure cases when they actually work on business start-ups.

This study was conducted to determine the effect of an exercise program applied to prevent musculoskeletal changes that occur due to aging on pain, muscle strength, balance ability, and falling efficacy in elderly women. An exercise program including quadriceps setting exercise, bridge exercise, resistance band exercise, and foam roller exercise was applied to elderly women aged 65 years or older once a week for 8 weeks. A visual analog scale was used to evaluate pain, muscle strength was evaluated using a digital muscle strength meter, balance ability was measured using the Berg balance scale, and fear of falling was evaluated using the fall efficacy scale. As a result of the study, compared to before the experiment, pain in the lower back and knee area was significantly reduced, the strength of the quadriceps femoris and gluteus maximus was significantly increased, and balance ability and falling efficacy were significantly improved. In conclusion, application of a program that includes various exercise methods has a positive effect on the physical activity of elderly women by strengthening the musculoskeletal system. Additionally, in order to prevent physical changes due to aging, an exercise program that includes various exercise methods that can strengthen the musculoskeletal system should be applied.

Purpose: This study identified the relationship between dietary habits and health-related behaviors depending on the Big Five personality factors (extraversion, openness, agreeableness, conscientiousness, neuroticism). Methods: The NEO-II test was administered to 337 male and female college students in Seongnam City, Gyeonggi Province, and their dietary habits and health-related behaviors were surveyed. Results: The male participants showed higher scores for extraversion, openness, agreeableness, and conscientiousness compared to that of their female counterparts, while the female participants showed higher scores for neuroticism. As for the results of multivariate logistic regression analysis, in the case of men, higher scores for extraversion were related to a lower intake of instant/fast foods and a higher intake of vegetables; higher agreeableness scores were related to a lower intake of fruit; and higher neuroticism scores were related to a heavy intake of high-cholesterol foods. It was found that higher openness scores were associated with a higher intake of burnt fish/meat and a lower intake of animal fat, while higher agreeableness scores were related to a lower intake of burnt fish/meat in women. Also, those subjects with higher openness and agreeableness scores were found to better consider the nutritional balance when having a meal. In the case of the male participants, higher openness scores were related to increased physical activity, while higher neuroticism scores were related to increased smoking and a lack of sleep. As for the women, those with higher extraversion scores smoked more, while those who recorded higher agreeableness scores were involved in more physical activities. Conclusion: Differences were observed in dietary habits and health-related behaviors between men and women depending on personality factors, and the analysis results of some dietary habits according to personality factors were inconsistent with those of the overseas studies. Therefore, to provide customized nutritional counseling when considering each individual's personality factors, more research results from domestic samples should be collected and accumulated.

The purpose of this paper is to examine the effects of computer/internet game play on depression and life satisfaction via perceived self-control among older adults in Korea. Data were collected from a survey of 237 community-dwelling older adults (age${\geq}$65) who reported internet users. A path analysis was used to examine the causal relationship among the main constructs. Results showed that the computer/internet game play had positive effects on perceived self-control. Perceived self-control was found to decrease depression and improve life satisfaction among older adults. Additional analysis indicated that the computer/internet game play in older adults did not directly affect mental health (depression and life satisfaction) but indirectly affected it via perceived self-control. Furthermore, perceived self-control had greater effects on depression than on life satisfaction. These findings have crucial implications in that perceived sense of self-control needs to be seriously considered when we develop mental health games for older adults.

The purpose of this study was to verify the influence of musical activities on social and emotional behavior of infants, through providing musical activities to the infants who were cared in a nursery and observing the interactions between peer group, or a therapist and an infant derived during them. The subject is 24 infants who are under 2 years of age(25~36months) at two nurseries located in Bundang area, and 13 infants among them are randomly assigned as study group and 11 infants as control group. Pretest and posttest about social and emotional behavior are performed, and ITSEA developed by Brggs-Gowan and Carter(2001) and amended by Shin Ji Yeon(2004) was used as an evaluation tool. Infants' changes of interaction behaviors during musical play were also analyzed quantitatively and qualitatively, and for the analysis, infant's social play behavior examination tool developed by Holloway and Reichhart-Erickson(1988) was adopted. Based on time sampling method, each item of this tool was evaluated. Each session was performed for 15 minutes, and 60 times of analysis about interactions per session was conducted at every 15 seconds. The analysis result was showed with a table and a graph, and described qualitatively about behavior changes. When compared social and emotional positive behavior average figures and negative behavior average figures between study group and control group, this study showed that the positive behavior figure of study group was increased and the negative behavior figure was decreased. While concentration and empathy among positive behaviors increased meaningfully, aggression, defiance, separation anxiety and rejection to new things among negative activities also decreased meaningfully. The conclusion of this study is as follows. First, interactions with peers or a therapist based on music and musical experience make an effect on strengthening positive behavior among social and emotional behavior and decreasing negative behavior. Second, music has influence on negative behaviors more than positive behaviors of an infant, and produces a good effect on sub behaviors of negative behaviors specially.

To investigate the factors which affecting the cognitive function and depression of the 65 or more age group, the authors surveyed for the subjects in the region of Taejon and nearby Taejon area. 729 studied subjects were tested for cognitive function with MMSE and depression with GDS. The main results were followings; In the studied subjects, the rate of normal cognitive function was 56.8%, the rate of mildly impaired was 24.1% and the rate of severe impairment was 19.1%. The cognitive function level was closely related to the depression score. As the age increased, the cognitive function was more impaired. Sexual difference was also existed in the cognitive function level and the depression score. After adjusting the effect of age, the variables such as sex, marital status, education level, past job, instrumental ability of daily living, regular physical exercise, frequencies of going out the house, chest discomfort, visual and auditory disturbance, and dizziness had the significant relationship with cognitive function impairment. Among these variables instrumental ADL, age, visual disturbance, and sex showed statistical significance in the logistic regression model. In the multiple stepwise regression, the variables which had significant relationship to depression score were education level, frequencies of going out house, current job and house work activity, regular physical exercise, instrumental ADL, self-rated health and nutritional status, dimness, visual disturbance, and chest pain. In conclusion, main characteristics which had close relationship to the cognitive function and depression symptoms in the studied subjects were physical function and self rated health status.
