Objectives : The purposes of this study were to investigate the recognition of Mibyeong, symptom, management plan and correlation between quality of life and health condition, and to suggest a plan for managing Mibyeong status. Methods : Participants were recruited based on the same sampling methods used on the previous study performed in 2013 based on area, gender and age. Questionnaires were collected by Gallup Korea professional surveyor through face-to-face interviews. The questionnaires contain questions about the recognition of Mibyeong, symptom, management plan and the quality of life in accordance with the relevant health conditions. Descriptive statistics were used for data analysis and the results were expressed as percentage ratios (%). Results : 1,100 of people were acquired in 2015. The responses for "First time to hear of Mibyeong" have shown that the percentage were reduced from 80% to 67% compared with 2013 data. The ratio of Mibyeong's symptoms in 2015 were similar to 2013. we suggested some ways to deal with the Mibyeong status including behavior adjustment (non smoking, non alcohol, control sleep pattern), herbal tea, health functional food, exercise, preventive health care (qi-gong, yoga), meditation, home health care medical device (hot-pack, seat device for fumigation, massager), and medical service (hospital, medical clinic oriental medical clinic). Almost people showed that positive opinion with them. There were significant correlation between quality of life with the health status rather than Mibyeong or disease group. Conclusions : This study was performed through scientific questionnaires collected in 2013 and 2015 to investigate people's understanding of Mibyeong as a present condition in Korean public. Some questions had significantly different responds between both years while others showed similar trends for both years. These results suggest that the concept of Mibyeong in oriental medicine could provide a management mechanisms that help people to manage the Mibyeong status.

Objectives : The purposes of this preliminary study was to examine the feasibility of recruiting women into a clinical trial designed to examine the effects of acupuncture in treating urinary incontinence (UI) in premenopausal women with delivery history and the feasibility of performing the study procedures. We also tried to determine if there was preliminary evidence to suggest that acupuncture may be effective in reducing UI and improving disease-specific quality of life. Methods : This study was a pragmatic randomized clinical trial. Subjects between the ages of 20 and 49 years were randomly assigned to a treatment(n=11) or control group(n=11) and analyzed. Both groups were supposed to do Kegel exercise at home during 4 weeks and acupuncture was applied to the treatment group twice a week(8 sessions) additionally. Subjects performed 1 hour pad test and completed a 3-day urination diary, international consultation on incontinence modular questionnaire(ICIQ), and incontinence - quality of life(I-QOL) at base line and 5 weeks. Results : Both group showed improvement in 1 hour pad test and the reducing amount of UI was significantly larger in treatment group(p=0.0182). The significant improvements in ICIQ and I-QOL were also observed in treatment group and sustained until the follow-up measurement at 16 weeks. Any adverse reaction related to acupuncture did not happen. Conclusions : It was feasible to recruit subjects and perform the study procedures. The positive results of this study support the requirement for additional research investigating the efficacy of acupuncture in the treatment of UI in women.

This study investigated physiological and subjective responses to different types of firefighter station uniforms made with various designs and materials. Six healthy males participated in this study that consisted of 20 min of rest, 30 min of treadmill exercise, and 30 min of recovery in a hot and humid environment (34℃ and 65%RH). The experimental clothing conditions were as follows. 1) a fitted T-shirt and trouser made of 100% polyester (FC-Uniform), and 2) flame retardant T-shirts made of acrylic and cotton as well as trousers with aramid and polyester, designed for overfitting (Control). There were no significant differences in the body temperature, and sweat rate between the two conditions; however, the heart rate with the FC-Uniform was significantly lower than Control (p=.025). The clothing microclimate temperature at the chest of the FC-Uniform was significantly lower than the Control (p=.037), and a difference of 1℃ was maintained until the recovery was complete. There were no significant differences in the subjective responses; however, participants experienced a humidity sensation faster with FC-Uniform in the recovery phase. The results indicate that changes in the design and material of firefighter station uniforms may have a positive influence on reducing the thermal stress of firefighters.

Background: The number of old people with degenerative osteoarthritis one of the chronic disease, were constantly increased. Many researchers have made a great effort to verify the effects of ultrasound and laser therapy in degenerative osteoarthritis treatment. This study applied ultrasound-laser integration therapy on knee joint degenerative osteoarthritis and compared its effect with ultrasound and laser. Methods: We assigned 60 patients age 65 to 85 who had been diagnosed as knee joint degenerative osteoarthritis in G nursing home in Daejeon city. Randomization was done in blocks of three, holding twenty people per each group to receive either ultrasound, laser, ultrasound-laser integration therapy. This study carried out the experiment for 6 weeks to from April 17, 2010. We measured variables using visual analog scale (VAS) and pressure threshold meter (PTM) of the effects by before and after exercise. Results: It has been found that VAS was reduced and PTM was increased in all three groups. Compare with the other groups, Ultrasound-laser integration therapy group had lower VAS and higher PTM than ultrasound therapy and laser therapy group. Conclusions: These results lead us to the conclusion that ultrasound-laser integration have influenced the pain reduction of the knee degenerative osteoarthritis.

Purpose: The purpose of this study was to identify the effects of health status and health management on activities of daily living (ADL) in older, urban-dwelling Koreans. Methods: A total of 206 subjects were recruited from one senior welfare center, six senior citizen centers, and subjects' home in two cities. Data was collected with self-reported questionnaires in order to measure health management, health status, and ADL. Data was analyzed by t-test, ANOVA, and stepwise multiple linear regression using SPSS/WIN 22.0. Results: ADL in this subject were different depending on their age, education, marital status, type of family, and average monthly living expenses. Multivariate analysis showed that age (${\beta}=-0.35$, p<.001), exercise ability (${\beta}=0.20$, p<.001), diabetes (${\beta}=-0.17$, p<.001), osteoarthritis (${\beta}=-0.15$, p<.001), caregiver (${\beta}=0.14$, p=.005), frequency of health management (${\beta}=-0.13$, p=.006), smoking (${\beta}=-0.11$, p=.019), hypertension (${\beta}=-0.10$, p=.027), and type of family (${\beta}=-0.10$, p=.036) were significantly associated with ADL. Overall, approximately 60.2% of total variability in ADL could be explained by the 11 variables in this model ($R^2=0.602$, F=32.06, p<.001). Conclusion: This study suggests that individualized health care should be continued for older, community-dwelling Koreans in order to improve their ADL. Moreover, we need to develop self-care programs and encourage them to participate in those programs.

The purpose of this study was to investigate the factors influencing body mass index of 618 university students located in the Gwangju area, from Nov. 20th to 30th, 2002. The subjects included 301 males(48.7%) and 317 females(51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index(BMI) was 3.7, 88.0 and 8.3 for the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time(65.1%) of the cases. Self-reported eating habit problems were eating irregular meal(52.4%), overeating(21%), prejudiced meal(12.4%) and skipping meal(7.4%). The type of favorite snack was biscuit(31.9%) and cup Ramyon(31.9%). The type of favorite beverage was juice(23.3%). The coffee intake was higher in males compared to females. The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 2.8% respectively. Percentages of weight control experience were 30.2 and 51.4 in the male and female, respectively. The BMI of students living in home and eating breakfast was higher than that of the other students. The BMI of students eating cup Ramyon and water increased. The BMI of students taking regular exercise and weight control tended to be higher than that of subjects not doing so. When the amount of pocket money available and the rates of coffee intake, alchol drinking and smoking increased, the BMI was increased. Therefore, nutritional education for university students is needed so as to improve their health and to modify life habits and nutritional education program should be developed to meet the various needs of these students.
