The purpose of this study was to evaluate far-infrared clothing (FIR condition) with non-far-infrared clothing (Control condition) to assess the effects of FIR on thermo-physiological responses. Eight young healthy males (23.0±2.3 yr, 176.5±3.7 cm, and 69.0±4.3 kg) participated in this experimental trial, which consisted of a 20 min rest followed by a 40 min walk (4.0 km·hr^-1) and a 20 min recovery at 20℃ with 50%RH. The results showed that finger skin blood flow and mean skin temperature were significantly higher for the FIR condition than the control during exercise and recovery (p<.001). Clothing microclimate temperature of the FIR condition was 0.5℃ higher on the back (p=.001) and 0.4℃ higher on the thigh (p=.015) during recovery. Clothing microclimate relative humidity of the FIR condition was 13% higher on the chest (p=.006) and 19% higher on the back (p<.001) during exercise than control. Subjects felt warmer and more comfortable in the FIR condition than in the control (p<.05). Perceived skin wettedness (%BSA) was less in the FIR condition than in the control (p=.001). These results indicate that ceramic-embedded clothing had significant effects on thermoregulatory responses for light activity in an indoor environment.

PURPOSE: The aim of this study is to verify the effectiveness of modified constraint-induced movement therapy(mCIMT) on upper function and activities of daily living in people with subacute stroke patients. METHODS: Eighteen participants, with subacute stroke that were randomly assigned to either the experimental group(n=9) or the control group(n=9). For subjects from the experimental group modified Constraint-Induced Movement Therapy was performed. exercise program, the patient trained in affected side upper extremity with restricted non-affected side for 1 hour and using in activity daily living for 4 hours for five times per week, during 4 weeks. For subjects from the control group, conventional upper extremity training was performed. Outcomes such as the box and block test(BBT), Fugl-Meyer motor function assessment(FMA), and modified Barthel index(MBI) were measured before and after training. Between-group and within-group comparisons were analyzed by using Independent t-test and Paired t-test respectively. RESULTS: These finding suggest that experimental group was significant increase in BBT, FMA, MBI(p<.05). In comparison of two group, experimental group was high upper function and activity daily living than control group. CONCLUSION: This study showed experimental group can be used to improve upper function and activity daily living than control group. Thus it indicates that mCIMT will be more improved through the continued upper extremity exercise program.

PURPOSE: The aim of this study was to provide evidence for the treatment of Forward Head and Rounded Shoulder Posture (FHRSP) using posture correction exercises by comparing muscle activity and onset time around the neck and shoulder area during an arm elevation task. METHODS: The subjects were divided into FHRSP (21 persons) and non-FHRSP (19 persons) groups to measure muscle activity and onset time of muscle contraction. Wireless surface electromyography was used to assess the muscle activity and onset time of the right and left sternocleidomastoid (SCM), splenius capitis, anterior deltoid, middle deltoid, serratus anterior, upper trapezius, pectoralis major, and infraspinatus during an arm elevation task. After the pre-measurement, the participants performed the postural correction exercises, and then the post-measurement was conducted. RESULTS: After the posture correction exercises, there were significant differences in the muscle activity and onset time of all muscles in the FHRSP group. The results of the comparison of the muscle onset time during an arm elevation task demonstrated that after the postural correction exercises, the muscle onset time was significantly reduced in the right and left SCM and left splenius capitis, but there were no significant changes in the onset time of other muscles. CONCLUSION: The results of this study help us understand the change in muscle activities and muscle contraction onset time in a person with FHRSP when lifting the arm and suggest the relevant basis to apply the posture correction exercise in clinical settings.

Purpose: The purposes of this study were to check the obesity of middle and high school students in the nation and identify factors influencing their obesity. Methods: The present study is a secondary analysis research that obtained permission to use the primitive data of 10th (2014) Online Survey on Adolescents' Health Behaviors by the Korea Centers for Disease Control and Prevention and analyzed the primitive data according to the purposes. Results: The findings show that the BMI of middle and high school students in the nation was $20.7kg/m^2$ with the obesity and non-obesity group recording $27.0kg/m^2$ and $19.9kg/m^2$, respectively. Factors influencing the obesity of adolescents include gender, grade, educational background of parent, school grades for the last 12 months, satisfaction with sleep, fast food consumption, ramen consumption, intense and muscle exercise three times a week or more, subjective sense of health, stress, suicidal ideation, and hours of Internet usage per week. Conclusion: For the management of adolescent obesity, there is a need for obesity management programs taking the characteristics of male students into consideration. The possibilities of obesity grow according to the grades, which means that both the teachers and parents should offer more guidance on weight control in upper grades. The adjustment of adolescent obesity requires psychological health management including stress and suicidal ideation as well as diet control and exercise. It is also needed to apply a stepwise obesity management program according to the hours of internet usage and dependence on the internet

The purpose of this study was to analyze exercise related mechanical variables according to performance levels and Kumi-kata types in elite judo players (G1) and non-elite judo players, namely university players (G2). To achieve this purpose, three players in G1 whose main special skill was Morote-Seoinage and three university judo players(G2) was selected as comparative group. Then they were examined for distinguishing A and B types of Kumi-kata. Analyzed variables were the time required to show skills, knee degree, elbow degree. After analysing this study, conclusions were derived as follows. 1. In total necessary time of showing skills according to group of Kumi-kata type, G2 was longer than G1 in both A type (20.9%) and B type (23.7%). In necessary time of phase, in only 3P, G1 was shorter than G2 in A type (50%) and B type (75%). There was no difference in time required of 1P and 2P according to Kumi-kata type of group and in only 3P, B type was shorter than A type in both B type (75%) of G1 and B type (50%) of G2 2 There was no difference in elbow degree of offensive arm according to group of Kumi-kata type, however in A and B types, G1 could use skills by extending in kake phase, but G2 could use skills by bending. Elbow degree of offensive arm according to Kumi-kata type of group showed difference in E1. and F2 of G1. A and B types of G1 extended elbow degree in Kake phase, but G2 bent elbow degree so exercise program which could movable range extensively in Kake phase is needed.

This study was an attempt to investigate various factions, such as the calorie, nutrient intake, physical activity, blood lipids, obesity prevalence and body fat distribution on NIDDM male diabetics. General characteristics, physical activity and exercise levels of subjects were invesigated by interviewing, daily calorie and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participats : weight, height. Also waist and hip circumference were measured on 174 male diabetics to get waist-to-hip circumference ratio as index of the body fat distribution. For measurement of plasma lipids, 12-hour fasting blood samples were drawn The results of this study were summarized as follows : 1. At the onset of diabetes, the major self-diagnosed symptoms were polydipsia, fatigue, and body weight redution 2. The average of daily energy intake of male diabetics was 2106 Kcal which is 96% of the RDA Percentage of energy is that carbohydrate:protein : pat=70:14:16. 3. Among the NIDDM male subjects, 59% was exercise regularly. 4. Obese subjects above in the ideal body weight of 120% are presently 17%, but 39% of subjects were reported to be obese in the past. The mean BMI of the male NIDDM diabetics is 23.3${\pm}$2.6 and the past mean BMI was 25.2${\pm}$2.7 The mean WHR was 0.93${\pm}$0.10. 5. When diabetics were divided into obese and nonobese group according to RBW, energy intake, blood pressure, blood glucose and total cholesterol were not significantly different between the two groups, but LDL and VLDL-cholesterol were significantly higher in the obese group. 6. RBW did not correlate with cholesterol and triglyceride, but WHR correlated significantly with cholesterol and triglyceride. In conclusion, these results from a present study support previous findings indicating that not only the degree of obesity but also the localization of fat is a risk factor for diabetes.

Purpose: In this study differences in levels of performance and importance of nursing jobs were explored in relation to levels of work experience. Method: The sample was chosen by convenient sampling (N=363) and a cross-sectional study design was used. Frequencies and percentages were used for descriptive statistics. ANOVA was utilized to examine differences in performance and importance of nursing jobs among three groups of nurses, divided based on levels of work experience (less than 1 year, 1 to 4 years, and 5 or more years). Results: Regarding performance of nursing jobs, novice nurses provided more support for patients, but provided less assessment of patients (i.e., investigation of levels of nutrition and exercise, and observation of verbal, and non-verbal behavior, and levels of cognition). Regarding the importance of nursing jobs, nursing linked to exercise and activities, and post-operative and excretion care were considered to be less important among novice nurses than among experienced nurses. Conclusion: Different training programs should be developed and provided to nurses according to levels of work experience. By doing so, it will be feasible to minimize differences in quality of nursing care triggered by different levels of work experience.

Objectives : To analyze differences in health behaviors among the social strata in Korea by using the 1995 National Health and Health Behavior Survey Data. Methods : Study Participants numbered 2,352 men and 1,016 women aged between 15-64 years old, with housewives, students and non-waged family workers excluded. Health behaviors in this study were defined according to the recommendations of the Alameda 7 study. The measure of health behaviors was based on the Health Practices Index(HPI; 0-5 range, with the exclusion of snacking between meals and regularly eating breakfast) developed by the Alameda County research. The significance of the relationship between social strata and HPI was assessed by considering the adjusted means from the multi-variate model. Results : For men, incidence rates of never having smoked, no/moderate use of alcohol, regular exercise, and regular 7-8 hours sleep per night were higher in the upper social strate. Meanwhile, for women, incidence rates of never having smoked, no/moderate use of alcohol, appropriate weight, regular exercise, and regular 7-8 hours sleep per night were higher in the upper strata. HPI varied significantly among social strata in both sexes (p<0.001), a result which held true when adjusted for age, education, income, social insurance type, marital status and region. Conclusions : Health behaviors assessed by Health Practices Index(HPI) varied significantly among social strata for both sexes. Therefore, the existing gap in health behaviors among social strata can be corrected more effectively by target oriented health promotional activities.

Background: An 8-year-old girl had severe neck pain and stiffness after trauma. CT scan showed atlantoaxial rotatory subluxation (AARS). She had conservative treatment because she did not have neurological symptoms and spinal basilar artery dysfunction. Conservative therapy was halter traction twice for 4 weeks. However, pain and stiffness persisted. She had been recommended to have surgery from her physician, but she received manual therapy for non-surgical procedures. Methods: The joint mobilization, muscle energy technique, motor control exercise, and deep neck flexor (DNF) endurance exercise were applied as manual therapy and 10 session for 2weeks. Results: Clinical outcomes were measured at initial baseline, after 2 weeks, and after 6weeks. Active range of motion was completely restored after 6weeks and numeric pain rating scale was completely reduced after 2 weeks. The strength of neck flexor muscle recovered to normal after 2 weeks, and the DNF endurance was improved to 25 seconds after 2 weeks and to 42 seconds after 6weeks. Motor control capacity recovered to 30 ㎜Hg after 2 weeks. Conclusions: This case report describes the immediate and short-term clinical outcomes for a patient presenting with symptoms of neck pain following AARS. Clinical rationale and patient preference aided the decision to incorporate manual therapy as a treatment for this patient. Manual therapy has shown a successful recovery in AARS patients, more research is needed to validate the inference of this case report.

Purpose: The purpose of this study was to evaluate the effectiveness of a health promotion program utilizing action planning strategy for young adults. Methods: A non-equivalent control group pre-post-test design was used. One hundred three university students participated in the study. Participants in the experimental group (n=51) were provided the health promotion program utilizing action planning strategy for five weeks. The program consisted of weekly sessions that included action planning and group feedback. The control group (n=52) was provided with health information every week for 5 weeks. Program outcomes, including self-efficacy, physical activity health behaviors, total exercise time per week, daily cigarette consumption, frequency of alcohol drinking per month, nutritional health behaviors, and subjective health status, were assessed at baseline and at follow-up after 5 weeks. Results: The participants in the experimental group demonstrated significant increases in self-efficacy, physical activity health behaviors, weekly exercise time, and nutritional health behaviors and significant decreases in daily cigarette consumption than those in the control group. Conclusion: The health promotion program utilizing action planning strategy is a brief and effective intervention to promote health behaviors among young adults. Further investigation is warranted to assess the program's effectiveness among other age groups and populations at high risk for chronic illness.
