Objective: The purpose of this study was to investigate the effects of intensive gait training with body weight support treadmill training on gait and balance in stroke disability patients. Design: Randomized controlled trial. Methods: Twenty-six stroke patients (20 men and 6 women) participated in this study. All subjects were hospitalized patients. They were randomly divided into two groups: the experimental group (body weight supported treadmill training group, n=14) and control group (treadmill group, n=12). The mean ages were 52.07 years (experimental group) and 53.83 years (control group). Subjects in both groups received conventional training 10 times/wk. Subjects in the experimental group practiced body weight supported treadmill training for 30 minutes a day, 3 day/wk. Subjects in the control group practiced treadmill training for 30 minutes. The Berg Balance Scale (BBS) and GAITRite were used to evaluate balance and gait parameters (step length, cadence and gait speed) before and after the intervention. Results: BBS scores in the experimental group showed significantly greater improvement ($4.33{\pm}1.54$), compared with the control group (p<0.05). Significantly greater improvement in the gait speed ($24.13{\pm}4.53$ cm/s), affected side step length ($10.40{\pm}3.42$ cm), sound side step length ($11.97{\pm}3.29$ cm), and cadence ($23.88{\pm}5.52$ step/min), compared with the control group (p<0.05). Conclusions: Intensive gait training with Body Weight Support Treadmill Training may improve gait and balance in subacute stroke.

Objective: The purpose of this study was to examine the effects of hip joint exercise using an elastic band on dynamic balance, agility, and flexibility in healthy subjects. Design: Randomized controlled trial. Methods: Thirty-five subjects (between 19 and 23 years) were randomly allocated to two groups: hip flexion exercise (HFE) group (n=17) and the hip abduction exercise (HAE) group (n=18). The HFE group participated in flexion exercise of the hip joint using an elastic band for 50 minutes a day, three days a week for four weeks, while the HAE group participated in abduction exercises of the hip joint using an elastic band for the same period. Dynamic balance was measured using the timed up and go (TUG) test, agility was measured with the standing long jump, and flexibility was measured using the Schober's test (5 cm, 10 cm). Results: The HFE group showed significant differences in the TUG test, standing long jump, and the Schober's test (10 cm) after training (p<0.05). The HAE group showed significant differences in the TUG test, standing long jump and the Schober's test (5 cm, 10 cm) after training (p<0.05). However, there was no significant difference between the HFE group and the HAE group. Conclusions: Flexion and abduction exercises of the hip joint using and elastic band increased dynamic balance, agility, and flexibility in healthy subjects. Additional research on hip joint exercises using an elastic band for improving dynamic balance, agility and flexibility are necessary.

Objectives : To evaluate the DNA damage by hair dyeing in human lymphocytes Methods : Comet assays were carried out to evaluate the DNA damage in lymphocytes by hair dyeing. Twenty subjects were selected from women volunteers whose age ranged from 55 to 67 year old. All subjects had no smoking history. Blood samples were collected before and 6 hours after hair dyeing. DNA damage was evaluated by means of the tail moments, which were quantified by a KOMET 4.0 image analysis system. Results : The tail moments before hair dyeing showed no significant differences among subjects except for the high frequency group. The mean values of the tail moments in subjects with low and high frequencies of hair dyeing were 1.39 and 1.77, respectively (p<0.05). The tail moments after hair dyeing increased significantly, The mean values of tail moments in subjects before and after hair dyeing were 1.45 and 1.79, respectively (p<0.01). However, the difference levels of DNA damage in lymphocytes before and after hair dyeing were found to be slightly lower in both the dietary supplement taking group and high frequency group. Conclusions : The high frequency group appears to have a higher level of DNA damage than the low frequency group before hair dyeing. DNA damage in lymphocytes was found to be significantly higher in the volunteers after hair dyeing. In this study, the related factors such as high frequency and taking dietary supplements appeard to reduce DNA damage in lymphocytes after hair dyeing.

Objective : The purpose of this study was to analyze the effects of multisensory exercise on foot pressure sensitivity and balance for the elderly. Method : The subjects were 17 elderly women (11 for the experimental group and 6 for the control group) with a mean age of 83. The subjects all lived in senior residence centers in Seoul. Multisensory exercise was done twice a week for 40 minutes during a 12 week period. Exercise programs were changed every 3 weeks according to the principal of gradual progress of the exercise. In order to train the vision system subjects were asked to open and close their eyes during exercise. When it came to training the vestibular system, subjects stood and walked on high elastic mats with their bare feet. For the somatasensory system subjects always stood and walked with their bare feet. The sub-Metatarsal Pad Elasticity Acquisition Instrument (MPEAI) was used to measure foot pressure sensitivity. MFT Balance test (V1.7) was used to measure anterior / posterior and medial / lateral directional balance. For the statistical analysis the IBM SPSS 21.0 was used to perform Repeatde measured ANOVA and Wilcoxon ranked test. Results : For the multisensory exercise group Hallux (after 6 weeks, 12 weeks), heel (after 6 weeks) and 2nd Metartarsal $40^{\circ}$ (after 6 weeks) pressure sensitivity increased statistically, but the control group didn't change. Also, balance didn't change for the experimental and control group statistically. Conclusion : Exercise with bare feet on a high elastic mat had a partially positive effect on foot sensitivity.

The efficacy of a medicinal herb tea (MHT) for assisting smoking cessation and for reducing withdrawal symptoms was evaluated by a placebo controlled subjective test in 100 male smokers. The MHT group experienced less craving for the taste of tobacco, and was more successful at quitting smoking. Among the subjects continuing to the final stage, 23 subjects (38.3 %) who took the MHT and 2 subjects (10.0 %) who took the placebo tea succeeded in quitting smoking. In the group taking MHT, urinary cotinine concentration increased during the first 2 weeks and then greatly decreased from weeks 2 to 4. The urinary cotinine concentration in the MHT group at week 0 was 38.6 mol/L but decreased to 24.5 mol/L by the end of week 4. MHT also reduced withdrawal symptoms, a frequent reason for failure in reducing or quitting smoking. The effects of the herbal tea on smoking cessation and withdrawal symptoms may be attributed to increased metabolism of nicotine and other effects of unidentified components of the herbal ingredients.

Purpose: This study was conducted to examine the effects of an educational program based on mobile SMS and counseling for colonoscopy in elderly people. Methods: The study utilized a non-equivalent control group with a non-synchronized design as a quasi-experimental research. The study subjects consisted of 72 elderly people (36 elderly people in the experimental group and 36 in the control group). Among the subjects, 49 were male (68.1%) and 23 were female (31.9%), and the age was 69.04±6.14 years. Forty-five subjects (62.5%) answered that they had underlying diseases, eight subjects (11.1%) had a family history of colon disease, and 61 subjects (84.7%) had undergone a colonoscopy. The experimental group was provided with an educational program based on mobile SMS and counseling when three days and one day before the test. The control group received verbal explanations using information sheet. The data were analyzed using descriptive statistics, the Chi-squares test, and the independent t-test with SPSS/WIN 21.0. Results: Significant differences were found in bowel cleanliness scores (t= 3.60, p= .003) between the groups. No significant differences were seen between the groups in the sedation drug dosage (propofol (t= 1.02, p= .730), midazolam (t= 0.66, p= .380)) and time for colonoscopy (t= 1.08, p= .235). Conclusion: Based on the results of this study, an educational program based on mobile SMS and counseling for colonoscopy was proposed as an educational program before colonoscopy.

The purpose of this study was to investigate the effects of smartphone use on muscle fatigue and tenderness in the cervical erector spinae (CES) and the upper trapezius (UT) and on the cervical range of motion among subjects with and without neck muscle pain. The subjects were 30 smartphone users in their 20 s who -were assigned to either an experimental group with neck muscle pain or a control group without neck muscle pain. Muscle fatigue and tenderness in the CES and the UT as well as the subjects' cervical range of motion were measured before and after 20-min smartphone sessions in a sitting position. In a between-group comparison of muscle fatigue, the experimental group showed a significantly greater decrease in median frequency in the CES and the right UT after smartphone use (p<.05). Regarding the assessment of muscle tenderness after smartphone use, the experimental group showed a statistically significant decrease in the pressure-pain threshold (PPT) in all muscles (p<.05), whereas the control group showed a significantly decreased PPT in the right CES and the UT (p<.05). The assessment of the cervical range of motion revealed a statistically significant reduction in the cervical flexion-extension and left lateral flexion in the experimental group (p<.05) after smartphone use. However, there was no significant change in the cervical range of motion in the control group (p>.05) after smartphone use. When compared with the control group, the experimental group demonstrated greater changes in cervical extension, lateral flexion, and rotation, except for cervical flexion (p<.05). In conclusion, when smartphone users have pre-existing neck muscle pain, the use of a smartphone further increased muscle fatigue and tenderness in the neck and reduced PPT and the cervical range of motion.

This study was conducted to investigate nutritional knowledge, dietary attitudes, and dietary behaviors of adult women, and to examine if these characteristics were different by acne status. Subjects were 106 adult women residing in Seoul recruited from clients and employers at skin care centers, and housewives from apartment complexes. Surrey instrument was adapted or modified based on literature review and dietary intakes were assessed using 24-hour recalls for two days and CAN-pro. All data was statistically analyzed using x$^2$test and ANOVA. When examined by acne status, 41.5% of subjects were categorized into acne group, 20.8% were as ex-acne group, and 37.7% as no-acne group. Parental experience of acne was significantly related to acne status(p〈 0.01). Education, employmental status, and smoking or drinking status were not related to acne status. Subjects had a moderate level of nutritional knowledge(72.7 point) and the nutritional knowledge store was not significantly different by acne status. When examined by individual items, the groups showed significant difference on the items regarding vitamin C and necessity of carbohydrates(p 〈 0.05). Subjects showed favorable dietary attitudes. Although the acne group showed more favorable attitudes on the importance of nutrition on acne, the overall dietary attitudes of the acne group were not significantly different from the ex-acne group or no-acne group. Similarly only small differences were noticed in dietary behaviors or nutrient intakes by acne status. Cholesterol consumption was hitgher in the no-acne group than in the acne group or ex-acne group(p 〈 0.01). The intakes of energy, iron, and calcium was much below the RDA in three groups. Although there were not many significant differences in nutritional knowledge, dietary attitudes, and dietary behaviors by acne status, this study provided some baseline information regarding study variables by acne status.
