Fouett$\acute{e}$ turns are repeated pirouettes which begin as a normal pirouette en dehors but include a movement that allows the rotational momentum lost to friction to be regained once each revolution. The purpose of this study was to investigate on orientation density of head/trunk to the front with and without music to which dancers perform the Fouette turn in time. 10 female dancers($21.0{\pm}1.4$ years old, height; $165.3{\pm}3.9$ cm, weight: $50.5{\pm}5.7$ kg) who are the students of S University participated in this study. It took shorter time to perform one revolution of fouette turn with music (930 ms) than without music (961 ms), which reason may be the shorter time of phase 2 in which the rotational momentum is not produced but lost to fiction. Orientation density of trunk to the front was smaller with music (.176) than without music (.196), while the one of head had not significant difference between with and without music. And the path length of marker on $2^{nd}$ left metatarsal bone during one revolution was smaller with music (35.7 cm) than without music (40.2 cm) but the difference was not statistically significant (p=.267).

This study is to examine the factors affecting success of business withhigh accomplishments in customer recognition and financial aspect in the fashion industry. In addition, through survey on consumers and interviews on industry officials who concerned fashion brand, perceived success factors were compared between consumer and industry groups. This study selected a total of 20 brands, which were 5 brands per 4 categories(e.g., women, men, sports and casual wear), with high customer satisfaction and customer loyalty in consumer's perspective and high revenues, revenue growth, and profit rate in 2004 in a financial perspective. The survey on consumer group and interviews on officials in industry were conducted simultaneously. One thousand respondents were obtained from survey on consumers and 40 respondents were obtained from interviews on industry officials. Multiple regression analysis and t-test were used for data analysis via the SPSS 12.0 program. The result of this study was as following. From a consumer perspective, respondents recognized that both consumer satisfaction and brand revenues were positively related to brand factors of consumer, product and marketing. From an industry's perspective, consumer, product and marketing factors affected consumer satisfaction as a brand success factor. In comparison of perception difference in brand success factors between consumer and industry groups, industry group was more likely to concern about the importance of brand success than consumers. In addition, the consumer group perceived the most highly consumer factor as a brand success factor, followed by product and marketing and external environment factors, while industry group did in order of consumer, marketing, product, and external environment factors, which indicated significant difference in perceptions of the two groups. Through this study on consumer satisfaction to improve positive and amicable buying behavior and comparative analysis on difference of perception of consumers and industry on factorsfor financial ability and revenue increase, the foundation for strategy establishment of brand distinction in fashion industry can be provided.

Many researchers have studied on the lightness of automobile. These researches are such as a body shell, sub frame, fuel tank, engine etc. The transmission Part is a magnitude one in the aspect of weight. A drive shaft (propeller shaft) transmits the engine power to rear differential gear assembly. It is used in the compact car that is a single drive shaft. But in the case of long body cars such as SUV (Sports Utility Vehicle), truck and large vehicle, two or three divided drive shaft are used to prevent the vibration damage from a drive shaft that has been taken high torsion and rotation. This multi-divided drive shaft structure is so heavy because it is assembled by yoke, center bearing and solid spline axis. When the rear axle move up and down, the spline shaft adjust the variation of a length between the transmission and rear axle gearbox. In this paper, it is studied in the experimental method that is a bending vibration characteristic of slip in tube shaped propeller shaft. This type propeller shaft is developed to combine the spline axis with drive shaft and can be light in weight of transmission part.

This study was designed to identify how the incidence and severity of premenstrual. syndrome (PMS) correlate with the nutrient intakes and exercise habit of women. The subjects of this study were 299 women residing in Busan metropolitan city. Each subject was asked to complete a menstrual discomfort questionnaire (MDQ) for PMS and nutrient intakes. PMS symptom scores of women in their twenties ranked in order of severity were: behavioral change (2.45), followed by pain (2.36) and water retention (2.28), negative effects (2.20), autonomic reaction (1.91), arousal (1.87), decreased concentration (1.76) and decreased control (1.74). For Women in their thirties, the symptom of pain was the most dominant (2.93) followed by autonomic reaction (2.69) and behavioral change (2.54), and for those in their forties, negative effect (3.06) was highest, followed by pain (2.97) and autonomic reaction (2.86). The overall symptoms of PMS significantly increased with age (20': 2.07 points, 30': 2.34 points, 40': 2.47 points). There was no correlation of the BMI of the subjects with the symptoms of PMS, but there was a significant negative correlation between the symptoms of PMS and exercise frequency for women in their thirties and forties. Subjects in their twenties exhibited a significant negative correlation for PMS symptoms with the intake of carbohydrate (p < 0.05), calcium (p < 0.05) and vitamin E (p < 0.05). For subjects in their thirties, PMS symptoms were negatively correlated with the intake of calcium (p < 0.05) and vitamin C (p < 0.05); and in women in their forties, calcium (p < 0.01) and carbohydrate (p < 0.05) intakes were negatively correlated with PMS symptoms. This suggests that PMS represents the clinical manifestation of a nutrient deficiency state, especially calcium. Therefore, we concluded that nutrient supplementation and exercise management are likely to be of benefit in relieving PMS symptoms.

Purpose: This literature review was performed to assess the effect of raisins on human health. Methods: A review of Medline was conducted using the keywords: 'raisins, raisins and health, raisins and cardiovascular disease (CVD), raisins and cancer, raisins and diabetes, raisins and fiber, raisins and colon health, raisins and antioxidants, raisins and inflammation, raisins and dental caries'. The reference lists from previous review articles on raisins and human health and the California Raisin Marketing Board files were reviewed for additional studies. Results: Raisins have one of the highest polyphenolic content and antioxidant ORAC levels compared to other traditional dried fruits. Many of the polyphenols in raisins are well assimilated and bioavailable. Raisin consumption reduces low density lipoprotein (LDL) cholesterol, blood pressure and blood sugar, when compared to equal caloric carbohydrate snacks and is associated with a reduced risk of CVD. The anti-inflammatory and cancer chemopreventive effects of raisins are mixed. Raisin consumption reduces intestinal transit time and positively affects gut microbiota. Raisins produce sustained energy during long term athletic competitions equal to traditional sports energy gels, shots and jelly beans. Raisins produce a non-cariogenic oral environment and do not fit the American Academy of Pediatrics criteria to be considered a choking hazard. Conclusions: Based on the review of literature, consumption of raisins provide numerous health benefits for promoting general wellness and in the prevention of many chronic diseases including: CVD, type 2 diabetes mellitus (T2DM) gastrointestinal diseases, and dental caries.

This study was to analyze the Life-Cycle Physical Activity Therapy Programs (PATPs) in Hoseo Region and to suggest the Activation of the program. The subjects were the 81 PATPs performed in 36 of the Community Health Centers in the region. The basic data was collected by Official Documents, the Homepage of the Centers, Telephone Interview, and e-mail with the person in charge of the programs. All the data were classified to the administrative districts (Rural, Urban-Rural Intergration and Urban Region), the Life Cycles (Children, Youth, Adult and Old Adult) and the Health-related Fitness Variables (Strength/Muscle endurance, Flexibility and Aerobics). The ACSM's (American College Sports Medicine) Guidelines for Exercise Testing and Prescription were used to evaluate the PATPs. In the results, the number of the PATPs was too low compared to the population. Also, the PATPs were not considered to the Life-Cycle proportion of the population. The management of the PATPs was principally inadequate. The frequency and duration of the PATPs were deficient in order to improve the Health-related Fitness. In conclusion, the number of the PATPs should be increased proportionally compared to the population, operated and developed on the Specificity of the Life-Cycle Population in the administrative districts. Further, the PATPs should be managed on the scientific knowledge of physical activity therapy.

Oxytocin (OXT) and serotonin (5-HT) are essential neurotransmitters associated with the behavior of animals. Recently, we found that the plasma concentration of OXT is positively correlated with horse docility and friendliness toward humans. However, the relationships between the neurotransmitters and other temperaments such as fearfulness, dominance, and trainability are unknown. This study aimed to identify whether the plasma concentration of OXT or 5-HT is correlated with fearfulness, dominance, and trainability of horses. Blood samples of 34 horses were collected at the Horse Industry Complex Center of Jeonju Kijeon College. The concentration of OXT and 5-HT was measured in the plasma samples using enzyme-linked immunosorbent assays. The fearfulness, dominance, and trainability of horses were scored by three professors who were very familiar with the horses. One-way analysis of variance with the least significant difference post-hoc analysis was used to compare the scores for fearfulness and dominance among groups. The trainability of horses was compared using the student t-test. The 5-HT was negatively correlated with dominance, but it had no relation with fearfulness. The OXT appeared to be negatively correlated with fearfulness and dominance in horses. Furthermore, OXT was positively correlated with the trainability of horses. Additionally, 5-HT appeared to enhance trainability. In conclusion, the concentration of OXT or 5-HT in horse blood plasma can be used as a biomarker to monitor the fearfulness, dominance, or trainability of horses.

This study was to analyze the Physical Activity Therapy Programs (PATPs) in U rban-rural region before and after COVID-19 in order to suggest a way of activating program. The subjects were the 43 PATPs performed in 4 Community Health Centers of Gimcheon, Jeongeup, and Pyeongtaek. The basic data was collected by official documents, expenditure budget, the homepage of the centers, national information disclosure portal, telephone interview, and e-mail with the person in charge of the programs. All the data were classified to the administrative districts, the health-related fitness variables, and the life cycles. The American College Sports Medicine Guidelines were used to evaluate the PATPs. As a results, the number of the PATPs was too small compared to the population of the regions. Also, the PATPs were not considered to the characteristics of participants such as Life-Cycle and regional facilities so on. The organization and management of the PATPs were principally deficient in improving health-related fitness variables. In 2020 as the period of COVID-19 pandemic, the number of programs and participants with face-to-face PATPs was significantlry decreased compared to 2019, while that was increased with non-face-to-face PATPs. In conclusion, PATPs should be increased and operated in accordance with scientific exercise prescription guidelines. Also, the programs should be considered with the proportion and characteristics of Life-Cycle population. Further, the various with non-face-to-face PATPs should be developed and screened with based on scientific data for post-corona virus pandemic. Further, non-face-to-face PATPs programs should include a kind of practical way to promote the individual physical activity.
