The objective of this study was to assess leg muscle activities during whole body vibration (WBV) training with various squat position exercises. Subjects performed four different squat exercises on a vibration platform (VM-10, Sonicworld Co.) Ten healthy women volunteers (age $21{\pm}1.3years$, height $160{\pm}2.1cm$, weight $52{\pm}4.6kg$) were selected. EMG signals four leg muscles were taken and analyzed. The exercises were performed both with 10 seconds WBV and without 10 seconds WBV. Muscle activities during WBV were compared with non-vibration stimulus. In the result, EMG signals caused by WBV were significantly higher (P<0.05) compared with non-vibration stimulus in all leg muscles and squat exercises. The increase in muscle activity caused by Whole body vibration was significantly higher (P<0.05) in LS and OS compared with HU&HS.

Objectives: This study aims to investigate the changes of women's postpartum symptoms, including their weights, edema index and quality of life (QOL) over the first six weeks after childbirth. Methods: The study participants were 31 postpartum women treated in the Dept. of Obstetrics & Gynecology, at Woo-Suk University Korean Medicine Hospital, from May 20th to August 5th, 2016. In the first 2 weeks of the postpartum period, the main data collection method was to interview each patient and write down all of their complaints, and additionally referring to each participant's PHR (Personal Health Records). At the 3rd, 4th, 5th and 6th week, the researcher interviewed participants by phone once a week. The participants' weight, edema index (ECW/TBW) and the quality of life (by EQ-VAS) were measured at 1st and 2nd week after childbirth. And, EQ-VAS was assessed once more at the 6th week after childbirth. As a last step, the participants responded to a survey on satisfaction regarding their postpartum care with Korean Medicine. Results: 1. In the 1st one week after childbirth, edema was the most frequent complaint. It was about joint pain of the upper limbs in the 2nd and 3rd weeks, sweating in the 4th week, and joint pain of the upper limbs in the 5th and the 6th weeks. 2. In the 1st two weeks of the postpartum period, the weight of the participants decreased from $66.33{\pm}9.30kg$ to $62.60{\pm}8.92kg$ (p<0.001) and the edema index ECW/TBW decreased from $0.399{\pm}0.010$ to $0.385{\pm}0.0 4$ (p<0.001). The EQ-VAS significantly improved from $61.77{\pm}17.72$ to $73.51{\pm}14.67$ (p<0.001). In the last 4-weeks of the postpartum period, the EQ-VAS decreased from $74.30{\pm}14.25$ to $73.63{\pm}13.35$, but this difference was not statistically significant (p=0.749). 3. Regarding the satisfaction with postpartum care with Korean Medicine, 60% of the participants responded that it was 'Excellent' and 40% said it was 'Good'. Conclusion: Over the entire postpartum period, the most frequent complaints were about musculoskeletal symptoms. Postpartum care with Korean Medicine treatments in the early postpartum period improves various postpartum symptoms and the quality of life for postpartum women.

The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

Objectives : The purpose of this study was to determine the effects of oral health on the quality of life of elderly patients with dentures or implants. It is our intention that through this analysis we can aid seniors in making the choice between dentures or implants, considering future masticatory function and the likely effects of this decision on the patients quality of life. Methods : This survey was conducted between November 1, 2010 and November 25, 2010, in Kyunggi-Do, whasung city. The research was carried out at one public health center, among elderly patients. 105 seniors were surveyed using the direct interviewing method, oral health related quality of life was measured by the Philadelphia Geriatric Center(PGC) Morale Scale. Collected data was examined using the SPSS 13.0 program, using frequency, mean, and standard deviation analysis, T-test and $x^2$ test. Results : The number of residual teeth for patients who have implants was $20.45{\pm}5.85$, while among those patients with dentures the number was considerably lower, $8.11{\pm}7.66$(p<0.05). The results of patients masticatory function, was $28.13{\pm}2.40$ for those with implants, and $25.35{\pm}4.15$ with dentures. The results were better for those with implants. Among implant patients overall satisfaction was rated $25.21{\pm}3.63$, higher than for those with dentures $20.20{\pm}6.79$(p<0.05). Quality of life was scored higher for patients with implants($12.76{\pm}2.61$) compared to those with dentures($10.47{\pm}3.52$)(p<0.05). The subjects masticatory function was highly related to the number of remaining teeth and greater masticatory function had a positive effect on patients quality of life and life satisfaction. Conclusion : Dental treatments such as dentures and implants will have a great influence on patients quality of life and life satisfaction. Implants can improve the oral health related quality of life and satisfaction and the general quality of life more than denture therapy.

This study was designed to examine the effect of sea buckthorn (SBT) leaves on hepatic antioxidative enzyme levels in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats by an injection of streptozotocin (STZ). Sprague-Dawley rats were then fed for four weeks, with experimental groups receiving a modified diet containing 10% or 20% powder derived from SBT leaves. The experimental groups were divided into six groups: a normal (N)-control group, N-SBT 10% and N-SBT 20% treated groups, STZ-control, STZ-SBT 10% and STZ-SBT 20% treated groups. Malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione-S-transferase (GST) and xanthine oxidase (XOD) levels were measured in liver cytosol. The results showed that the level of SOD was significantly increased in the N-SBT 20% group but not statistically different in the diabetic group. The level of CAT was significantly higher in the N-SBT 20% group compared to the control group. The level of GPX was significantly increased in the N-SBT 20% group and the diabetic supplementary group. In contrast, the level of XOD was significantly decreased in the diabetic group supplemented with SBT leaves.

Purpose: Due to the presence of various muscles around lips, variety of facial expression can be made and changes from aging process such as wrinkles can develop on the facial skin by the action of multiple muscles. In animals, skin and muscles are developed in the entire body. On contrast, they are well developed only in the face and just one is present in the neck and the palm. Alar band was defined as outer wrinkle formed by zygomaticus minor muscle, which is common in Koreans. This study aimed to investigate clinical prevalence of alar band. Materials & Methods: Subjects were chosen from 780 new patients who visited private clinic in Gyeonggi province for orthodontic treatment. Presence of alar band was examined from the smile extraoral photos. Correlation among skeletal form, lip protrusion, gender, and age were evaluated. Results: Prevalence of alar band was higher in women (27.9%) than in men (18.5%) with statistical significance (p<0.05). With respect to age, prevalence of alar band was 19.4% in age 0-9 y, 16.9% in age 10-19 y, 31.2% in age 20-29 y, 39.5% in age 30-39, 56.5% in age 40-49. Prevalence was gradually increased from patients in their 20s to patients in their 40s and statistical significance was found (p<0.001). Concerning SN_NP, prevalence was 26.2% in normodivergent facial type, 22.0% in hyperdivergent facial type, and 32.2% in hypodivergent facial type. Hypodivergent facial group had higher prevalence but statistical significance was not observed. Statistically significant difference was not found regarding upper lip. However, prevalence of the alar band was 26% in patients with normal lower lip, 14.7% in patients with pretruded lower lip, and 33.3% in retruded lower lip. The prevalence was higher in patients with retruded lower lip with statistical significance (p<0.05). Conclusions: 27.8% on previous anatomical study and this study showed 27.8% prevalence of alar band in clinical smile photographs. Clinical photograph study showed that alar band was more prominent in women, older people, and people with retruded lips with statistical significance. This will provide valuable diagnostic information for esthetic consideration.

The aim of this study is to investigate the expenditure items and expenses for companion dogs and the appropriate considerations when choosing companion dog food for consumers who purchase dog food through the internet. The survey subjects consisted of 39 males (6.8%) and 532 females (93.2%), and it was found that most women purchase dog food through the internet. According to the age of dog owner, 184 (32.2%) were in their 20s and 241 (42.2%) in their 30s and 146 (25.6%) in their 40s or older. According to the age of the dogs, 200 (35%) were under 3 years old, 202 (35.4%) over 8 years old, and 169 (29.6%) were between 4 and 7 years old. The most preferred ingredient was chicken, regardless of dogs' owner or the dogs' age. Spending less than 100,000 won was most frequency reported, regardless of dog owner and the age of the dog, and major dog food was reported to be purchased in the order of online shopping malls and animal hospitals. In order to improve health function, it was determined that improvement of skin and hair is the most important, and next, was improvement of tooth bone formation and digestibility. When choosing food for companion dogs, nutritional composition of all the products was the most important consideration, followed by brand products with recognition, color, smell, shape, functional improvement products, and price of the products. Therefore, when developing a new product for companion dog food, consideration must be given not only to the nutritional components of all products, but also the brands, color, odor, shape, nutritional balance, functional improvement and price.

This study was conducted to investigate the changes of physical and psychological factors of obese children, obesity indices and blood serum levels, food habits and body and self-esteem after a weight control program. The results from this study were as follows: Participants of the study involved 20 boys (48.8%) and 21 girls (51.2%) totaling 41 children. Children's weight control experiences were 90.2% and parents' were 59.5%. Among methods of weight control, children and parents both used exercise and reduced amounts of meals. Sixty-one percent of the children had breakfast almost everyday. The reasons of skipping breakfast were having no time to eat by 44.4% and 50% of children watched TV while having a meal and they considered taste (55.3%) and nutrition value (21.1%) when choosing food. After the weight control program, the children's body fat percent (%) significantly decreased from 40.3% to 35.4% (p < 0.01). There was significant difference of boys and girls' hip circumferences (92.9 cm, 91.4 cm, p < 0.01) after the program but there was only a slight change in their WHR (0.91, 0.92). Girls' waist circumferences significantly decreased from 75.0 cm to 73.0 cm (p < 0.05) and there was a significant increase in HDL-cholesterol, 50.0 (mg/dL) to 55.2 (mg/dL), (p < 0.05). Knowledge levels of obesity significantly increased from 2.5 to 5.1 in the girls' cases (p < 0.001). Nonetheless, attitudes of weight control and food habits score had not changed a lot. After the program, both the boys and girls' body-esteem had significantly increased (p < 0.01) but self-esteem had not changed. These results suggest that a body weight control program must be included in nutrition education, exercise and psychotherapy to improve body and self-esteem of obese children.

The aim of this research was to develop a practical use of the citron (Citrus junos Sieb.) leaf, which is a by-product of the citron cultivation, by introducing it into the Jeolpyun, one of the most popular rice cakes in Korea. To achieve the goals of this research, the citron leaf Jeolpyun (CLJ) was first precipitated. The sensory properties and physical examination of products containing 0 (control), 1.0, 1.5, 2.0, and 2.5% of the dried citron leaf powders were then assessed by employing sensory evaluations and instrumental measurements for texture and color. A total of one-hundred and fifty women panelists in age categories of 20s, 30s, 40s, and over 50 were randomly selected from residents in the Seoul area. In general, the highest sensory evaluation scores were obtained for CJLs containing 2% of the citron leaf powders by all panel groups although there was some variation. As levels of the citron leaf powder in the CLJ increased, the texture parameters such as hardness, cohesiveness, and gumminess of the CLJ as measured by the Texture Analyzer significantly increased while adhesiveness decreased and springiness remained constant. Accordingly, the optimal amount of citron leaf powder was determined to be 2% or less for CLJ in order to maintain the original texture of the Jeolpyun. As the levels of the citron leaf powder increased in the CLJ, the Hunter colorimetric L-and a-value significantly decreased while the b-value significantly increased. In other words, the CLJs became darker, as well as deeper in green and yellow tones as the levels of the citron leaf powder increased. The above results indicate that the citron leaf could be successfully used for preparation of Jeolpyun at a concentration around 2%(w/w) based on the consumer preference test and instrument analysis of the products. This research is expected to contribute to the industrial use of citron leaf powder in Jeolpyun and other food products.

This study aims to provide basic materials for marketing strategies of cosmeceuticals by investigating customers' recognition and satisfaction about cosmeceuticals targeting 161 adult men and women in their 20s to 50s and living in Seoul, Korea and then analyzing what should be improved for customers. According to the survey, many customers prefer cosmeceuticals due to the professionalism recognized by hospitals, the recommendation by doctors and the scientific image, though the recognition about cosmeceuticals is low among customers in their 40s or older because they are unfamiliar with the term. The survey also shows that the satisfaction about cosmeceuticals is very high in that 94.41% out of 49.85% total users said they were willing to repurchase them, while 72.22% out of 50.15% total nonusers said they wanted to purchase them. The greater knowledge about skin, the higher the interest in cosmetics and the aesthetic practice rate. When it comes to comparing cosmeceutical users and nonusers in choosing cosmetic products, the greater knowledge about skin, more nonusers consider brand recognition (r=.222, p<.05) and cosmetic ingredient (r=.245, p<.005); and more users convenience (r=.162, p<.05). Now that total customers' awareness of cosmeceuticals remains low yet, therefore, it is considered necessary to steadily promote them, enhance repurchase factors, and come up with strategies differentiated from ordinary cosmetics.
