mankind has evolved to stand upright a million years ago. However entering an industrial society, much has changed in only a few decades. Human beings spend more time sitting down and working, which negatively affects their bodies. Leading medical studies have shown that the prolonged working conditions have significantly affected the causes of adult illnesses that we have known. Human beings have evolved in a moving direction. So, like modern societies, sitting or standing in one space for long periods of time without movement brings various side effects to the body. Reflecting this background, this study has led to think of work in an environment that is taking the evolutionary biology perspective from a traditional standing, standing work environment. They also plan to conduct an experiment to handle work with smartphones in the hopes of expanding their mobile office environment to use smartphones in the field, which is a type of smart work. The study could help build and establish a mobile office environment, a type of smart work. In addition to using smartphones, a working environment can be created that works by moving around. Furthermore, the paradigm of the work environment of businesses and students could be changed.

The purpose of this study is to investigate the change of balance ability on aging by measuring balance ability of elderly females whose age is over 65. The subjects are ten elderly women (the mean age: 71.9) able to walk without assistants, the assistant equipments and drug dependence and ten young healthy women (the mean age: 23.2). We measured stability index (ST), Fourier index (F), weight distribution (WD), weight distribution index (WDI), synchronization index (SI) and fall index (FI) by using Tetrax (Tetra-ataxiometric Posturography). In result, STs and Fs at the low frequency region (F1) represented the significant difference between two groups at all postures with PO (pillow with eye open) exception (p<.01). Fs at the other frequency regions (F2~F8) represented the significant difference between two groups (p<.05). WDI of the elderly women represented the higher values than the young women at all postures but there are the significant difference at PO and PC (pillow with eye closed) only. These results may be due to age-related ability decline of somatesthesia, vestibular organ, central nervous system.

This study examined the correlation among the Korean language ability, health promotion behaviors and health status of immigrant women by marriage. Data on the subjects of 148 immigrant women were collected from September to December, 2013. Constructed self-administered questionnaires were used to gather information on the general characteristics of the immigrant women, their Korean language ability, health promotion behaviors and emotional health status. The health examination results of the subjects were used for information on their health status. There were significant differences in the Korean language reading ability, drinking habits, total cholesterol and body mass index between the diseased group and the intact group. An analysis of the relationship between the Korean language ability and health conditions revealed a significant positive correlation between the total cholesterol and neutral fat, but negative correlations between the density of hemoglobin and the total cholesterol, the neutral fat and body mass index. There was a significant negative correlation between the Korean language ability and the level of stress. Based on these results, a program was suggested and developed to decrease the rate of drinking, cholesterol and body mass index of immigrant women and to promote their ability to understand health information and express their diseases properly in the Korean language.

Purpose : The purpose of this study is to compare the growth pattern of breast fed and formula fed infants in the first 1 year of life. Methods : Anthropometric data(weight, length, head circumference) of at birth, 1, 3, 6, 9 and 12 months were collected by chart review and characteristics of subjects were collected by questionnaires. Among 358 infants, breast fed infants were 161(84 males, 77 females) and formula fed infants were 90(42 males, 48 females). Neither group was given solid foods before 4 months. The weight for age, length for age and head circumference for age were calculated. Breast fed infants were separated into 2 groups(breast fed for 4-11 months and breast fed for more than 12 months). Results : Characteristics of infants and mothers were similar in both groups except for maternal age. Mean weight of breast fed group was lower than that of formula fed group at 12 months of age(male : P=0.004, female : P=0.004). However, mean weight of 12 months breast fed group was below formula fed groups weight at 9 and 12 months(P<0.05). Mean length and head circumference were similar between groups. Conclusion : The growth indices of breast fed and formula fed infants are similar at birth, but weight curves of two groups differ in the first 1 year.

Purpose : Insulin resistance is the most important risk factor linked to the development of impaired glucose tolerance(IGT), diabetes mellitus and cardiovascular diseases in childhood and adolescent obesity, The purpose of this study was to see whether insulin resistance of obese adolescent is higher than that of obese children. and to analyze gender difference and affecting factors of insulin resistance. Methods : Of the 9,837 school children from 5 to 16 tears old, 92 obese children and 187 adolescent, underwent a two-hour oral glucose tolerance test and plasma glucose, insulin, lipid profiles, leptin and high sensitive C-reactive protein(hs-CRP) were measure. Results : Plasma insulin levels of female were higher compared to those of males during oral glucose tolerance test(P<0.05). Four(4.3%) in obese children and twenty five(13.3%) in obese adolescents met the criteria of IGT. Female, leptin, adiponectin and triglyceride concentrations were strongly correlated with homeostatic model assessment insulin-resistance(HOMA-IR) by multiple linear regression analysis(P<0.05). Conclusion : Obese adolescents might have higher insulin concentrations compared to obese children and obese girls higher insulin concentrations than obese boys. Obese boys and children with impaired glucose tolerance have higher insulin concentrations than those with normal glucose tolerance. HOMA-IR was significantly correlated with female, plasma leptin, adiponectin and triglyceride concentrations.

This study examined the factors associated with recurrent falls among the community-dwelling elderly. The participants were 329 community-dwelling elderly. The data was collected from February 5, 2010 to February 14, 2010. Over the past 1 year, 14.3% of the 329 participants fall once, and 4.0% experienced recurrent falls. There was a significant difference among the non fallers, single faller and recurrent fallers with regard to the static balance(F=5.86, p=.003), dynamic balance(F=24.32, p<.001), risk of fall(F=9.94, p<.001) and compliance of prevention behavior related to falls(F=3.09, p=.047). The analysis results for the correlation between variables showed that the number of falls had a negative effect on the knee flexors muscular strength(r=-.15, p=.008), static balance(r=-.16, p=.004) and compliance of prevention behavior related to falls(r=-.12, p=.030) and a positive affect for the dynamic balance(r=.26, p<.001), depression(r=.13, p=.019) and risk of falls(r=.30, p<.001). The variables explained 36.0% of the variants in the occurrence of recurrent falls. Therefore, an effective recurrent fall prevention program should focus on multiple risk factor intervention.

The objective of this study is to analyze teachers' experience in the operation of outdoor play in an early childhood educational institute. For this purpose, the experience obtained in planning/operating the outdoor play in early childhood educational institutes, as well as the difficulties experienced in their operational process, were examined. The data was collected through interviews with eight early childhood teachers. In the results of the study, first, the teachers' perception of outdoor play was analyzed. The teachers considered outdoor play as meaningful in that the children could develop gross/fine-motor skills, have the chance to develop their sociality, relieve their stress, and also commune with nature through outdoor play. Second, regarding the plan/operation of the outdoor play activities, even though they aimed to provide the children with meaningful outdoor play activities through various materials and methods, most of the teachers could not put their original plans into practice, because of the numerous variables in the actual site. The teachers' difficulties included insufficient time, spatial limitations, and insufficient qualifications for play instruction.

The aim of this study is to identify the effects of the correction exercise program on femoral intercondylar distance, Q-angle and plantar pressure in undergraduate with genu varum. A experimental study with a randomized controlled trial design was used. Thirty subjects with genu varum were allocated in two groups: the experimental group (n=15) or the control group (n=15). The experimental group conducted correction exercise program for 30 minutes a day, 5 times a week, for 6 weeks, while the control group did not perform any exercise. The correction exercise program group showed a significant decreased femoral intercondylar distance, plantar pressure of M 4, M 5 (Metatarsal 4, 5). Also the correction exercise program group significantly increased Q-angle, plantar pressure of Toe 2-5 and M 1, M 2, M 3 (Metatarsal 1, 2, 3) (Rt, Lt) (p<.05). Thus, we suggested that the correction exercise program may be suitable intervention to improve normal alignment in undergraduate with genu varum.

This study examined the changes in the center of pressure (COP) and cadence according to three types of bags carried and three different bag weights. The experimental period was from June 3, 2013 to January 20, 2014, and thirty eight healthy adults (mean age: $26.10{\pm}5.32$ years, age range: 22-30 years) volunteered under three conditions. In the first condition, the subjects wore a bag over one shoulder and they walked. In the second condition, they carried a bag across the shoulder and walked. With the third condition, they carried a backpack using both shoulders and walked. 3-Dimentional motion analysis system and a force plate were used to measure the kinematic parameters of gait and COP displacement during gait. Each subject walked 6 meters carrying a 3kg, 5kg and 7kg bag under all three conditions. The COP of the antero-posterior and medio-lateral, and cadence variable were significantly different according to the bag weight of 3kg, 5kg and 7kg. These findings suggest that walking while carrying a backpack using both shoulders is more effective on the changes in COP and gait of adults than the other conditions.

It is well known that the exercising and stimulating of fingers have an important bearing on the brain. We take note of the fact and develope a game device for improving one's health and brain ability in respect of the education and training. Especially, we develope the device focused on the balanced exercising of five finger for improving brain function. The game device is possible to used in two-ways, namely online and off-line mode. In online mode, the device is connected with other visual devices such as smart phone and smart TV and communicated with Bluetooth and it is used as a MMI(multi-modal interface) device. Whereas, in off-line mode the game device works independently and it makes possible to enjoy auditorial and tactual games without video images for promotion of brain activity and emotional cultivation. For certification of the device, we implement two games(a fishing game for off-line mode and a shooting game for online mode) for people of all age, especially good for the elderly. It is usable as a game device to offering the elderly a great help for preventing impairment of the cognitive functions.
