Purpose: The purpose of this study was to provide data about the risk factors related to falls among elderly patients with dementia using meta-analysis. Methods: Key words used for search through electronic database (CINAHL, PubMed, Ovid-MEDLINE, RISS, KISS, DBPIA, National Assembly Library) included 'dementia', 'Alzheimer', 'fall'. Twenty studies met the inclusion criteria for the meta-analysis and 'R' version 3.2.2 was used to analyze the correlated effect size. Results: Study results showed that risk factors related to falls were identified as the demographic (age, gender, education), dementia-related (disease duration, cognition), physical (body mass index, walking, balance, activity of daily living, use of walking aids, number of medications including psychotropic drugs, musculoskeletal problems, parkinsonism, comorbidity), psychological (neuropsychiatric symptom, depression), environmental (Physical environment), and fall-related (fall history, high risk group of fall) factors. The effect size of risk factors such as high risk group of fall (r=.35), use of walking aids (r=.33), depression (r=.31), psychotropic drugs (r=.27), Musculoskeletal problems (r=.25) were higher than the other risk factors. Conclusion: Based on the findings of this study, strategies to improve elderly patient's depression, intensive care for high risk group of fall, and adequate training with walking aids are needed for prevention of falls in elderly patients with dementia.

The present study was performed to evaluate food behavior and nutritional status of children in a community child center using nutrition quotient according to age and growth index of children. The number of subjects enrolled in this study was 152 including 73 boys and 79 girls. Participants consisted of children from 5 to 12 years old, who visited a community child center in the area. Growth index was assessed through body mass index by height and weight and examined according to age. Subjects were divided into underweight, normal weight, overweight and obese according to questionnaire, which consisted of five categories including balance, diversity, moderation, regularity and practice, were analyzed by SPSS statistical program. Current results show significant differences in the diversity and regularity (p<0.05, p<0.001, respectively). Additionally, four items in the form of 10 questions showed significant differences related to habits of sodium-related food intake. This study design will be a useful tool in the evaluation of food behavior and nutritional status of preschoolers or elementary school children in community child centers, together with food frequency questionnaires related with sodium food intake.

Human body is hard to be in perfect balance during walking. Most of time the trunk is supported by one leg and the center of mass(COM) falls to the contralateral side. Thus, dynamic variables such as the velocity of the COM should be considered when gait stability is evaluated. The purpose of this study was to investigate whether the extrapolated center of mass(XCom) which utilized the COM position and its velocity, is appropriate to evaluate gait stability. Ten healthy adults participated in this study and performed 3 different types of gaits(normal(NG), hands on waists(HWG), and hands on shoulders(HSG)) onto 4 different types of obstacle(obstacle height: 0%, 30%, 40% and 50% of leg length). Medio-lateral Com-CoP and XCom-CoP inclination angle were calculated during support phase. For all condition, greater M-L XCoM-CoP inclination angles were found(p<.05) compared with those of matched obstacle height CoM-CoP. Especially, M-L XCoM-CoP inclination angle at 50% height revealed the best condition for monitoring dynamic stability. Significantly increased in M-L XCoM-CoP inclination angle was found(p<.05) as obstacle height increased on NG and HWG.

Protective clothing for firefighters typically consists of a flame resistant outer shell and inner layers. The inner layers are generally composed of a moisture barrier and a thermal barrier. On performing the task in fire place the heat and perspiration generated from the body become trapped inside the protective clothing. Those heat and moisture result into heat-stress and physical fatigue of fire fighter, which hinder the work. Therefore, the system of clothing designs and material layers must be chosen carefully to balance protection and comfort. 3 kinds of protective clothing of 3 layer structure were used in the experiment of physiological comfort. From the comparison of wear trials with the 3 kinds of layers in firefighters clothing, it indicates that the moisture dissipation of A+B2+C was highest, following A+BI+C andA+B3+C. And the heat dissipation of A+BI+C and A+B2+C were better than A+B3+C. In the protective clothing with A+B3+C, heat and perspiration generated through exercise remained in clothing system long and caused discomfort.

This study is aimed to research the actual wearing condition of ballet dancewear of girls aged between 2 and 6 years on its design, size and fit. Survey data were collected from 171 mothers who have a girl learning ballet dance. The questionnaire was composed with ballet education, ballet dancewear purchasing, preference on design, size selection, and fitting. The collected data were analyzed with frequencies statistics, ${\chi}^2$-test, ANOVA using the SPSS WIN 20.0. The results are as follows; High rate of respondents said that the purpose of ballet education was for good body balance, leisure activity, and height growth. The main method of purchase was online shopping. The design, price, size and fit were identified as important ballet dancewear attributes for girls. The most preferred style of ballet dancewear were 'short sleeve skirted leotard' and 'camisole skirted leotard' which look like dress. The respondents reported slight satisfaction with size and fit, price, convenience in action, sewing and durability. The most preferred sizing system was code by height but any ballet dancewear makers don't use code by height. Therefore it is difficult for consumers to select size. Retailers and manufacturers could potentially use the results of this study to improve the sizing system and fit for children's ballet dancewear.

Objectives The purpose of this study is to investigate that causes of motion sickness in oriental medicine. Methods The internal and external studies about motion sickness were searched Results and Conclusions The motion sickness is induced by conflict of balance system including vestibular, visual and proprioceptive system. The motion sickness is more common in female and in children between 2 and 12 years old. In western medicine, antihistamine and anticholinergic has been used for treatment of motion sickness, but these anti-motion sickness drug turn out to be not a perfect solution and have several side effects. On the other hands, In oriental medical terminology, there is no words equivalent to the "motion sickness", but we consider the motion sickness as state with dizziness, nausea and vomiting. The motion sickness can be induced by either internal or external causes and the internal causes can thought to be a constitutional factor of an individuals, and the general transportation can be an external cause. The important internal cause is a dysfunction of the spleen, stomch(脾胃不調), retention of phlegm and fluids(痰飮), and deficiency of the kidney jing(腎精不足). The wind(風) and fire(火) in the upper part of the body, especially in the head, also can be an important cause of the motion sickness.

Objectives: Intraoral appliances (IOA) are applied in the clinical practice of Korean medicine to improve the balance between yin and yang of the body such as temporomandibular joint balancing medicine. Historical examples of IOA were not well known. This study reports prototype IOA's described in medical classics. Methods: Several medical classics of 12th to 19th centuries were narratively reviewed for prototypical descriptions of IOA's in the context of clinical practice. Results: IOA's in the medical classics reviewed adopted such materials as bamboo, chopsticks, and coins that were adjusted in the height and were used as a temporary IOA's with response of the patient being monitored. IOA's were applied integratively with herbal medicine for diverse complaints such as pain, hearing problem, cough, asthma, and rhinorrhea. Conclusions: Prototype IOA's in the medical classics suggest an individualized, integrative, and holistic principle and usage of IOA's in the tradition of Korean medicine.
