Background : The purpose of this study was to investigate the relationship between an agility and a concentration, an auditory reaction time and a muscle power. Methods : Twenty one healthy female college students who were 20-21 years participated in the experiment; after being introduced to the methods, they voluntarily signed a consent form. And they received several test related with this study; side step test for an agility, Harris & Harris test for a concentration, brain auditory evoked potential test for an auditory reaction time and vertical jump test for a muscle power. Result : There was no relationship between the agility and the concentration and the auditory reaction time. However, the muscle power related with the agility significantly. Conclusion : In conclusion, these findings suggest that a muscle power training is a good way to promote an agility. So, we can find out that, in an player who requires an agility, a muscle power training is the most important way for promoting an agility than a concentration training or an auditory reaction time training.

This study was carried out to determine the mechanical and physical properties of particle boards glued with condensed tannin (Wattle Tannin) powder that was single-molecule phenolic compounds like powdered phenolic resin. Our findings are; 1) It is necessary to spray water on the chip surfaces for effective application of powdered -form tannin resin. It shows that the best and optimum mat moisture increase is 14% of water spray on the surface of chips for developing PB properties. 2) In general, for both liquid and powdered tannin adhesives, their physical and mechanical properties has been proportional to the increase of resin level. But, the most efficient addition ratio is 16% of resin on dry basis. Specially, it is found that the resin level influences on the amount of free formaldehyde emission. The higher the resin level is, the lower the emission is. These phenomena seem to result from the increase of hexamine or formaline in the adhesives used as a hardener, that reduce the free-formaldehyde amount by reaction of tannin of poly-molecule and water. 3) The optimum condition for manufacturing PBs is the condition of hexamine of 5% and formaline of 6% in mechanical and physical properties. Hexamine is superior to formaline in mechanical and physical properties along with the control of the free formaldehyde emission amount. The result of NaOH's addition is insignificant in all experiments of both mechanical and physical properties.

The aim of study was to investigate the effects of 12 forms of Sun-style Tai-Chi for arthritis(TCA) on physical symptom(pain, tenderness, swelling fatigue, and blood pressure), physical function(balance, flexibility, grip strength) and social-psychological health status in osteoarthritis(OA) patients and rheumatoid arthritis(RA) patients. This study was done with one group pretest-posttest design. A total 21 arthritis patients(6 OA patient and 15 RA patient) participated in 60 minute session consisting of warm-up exercise 12-main movement including qigong, and cool-down exercise twice a week for 6weeks. Physiological and social-psychological variables were measured before and after TCA 12 form. The researcher who completed a Tai Chi workshop for exercise leaders in Australia and Seoul taught the Tai Chi movement step by step until the patient felt comfort enough to perform them correctly by themselves during the first 4 weeks. At the last 2 weeks, the subject perform 10-15set of these at a session with traditional music to help patients move in a slow tempo. TCA 12 forms program showed significant improvement in fatigue(p=0.039) of rheumatoid arthritis patient and pain(p=0.006), fatigue(p=0.013), tenderness(p=0.032), flexibility(rt arm up, p=0.014, If arm up, P=0.003), grip strength(rt hand, p=0.002, If hand, P=0.003) of osteoarthritis patients. With assessment by Arthritis Impact Measurement Scale 2 questionnaire(AIMS2), physical component(0.002) and social interaction(0.025) on osteoarthritis patients were significantly improved. Evaluation of the participants about TCA exercise noted that the exercise was fairly easy(23.6%), moderately difficult(57.1%), and fairly difficult(14.3%). Considering the result of this study, TCA exercise program was more effective in pain, tenderness, grip strength, flexibility, and physical and social interaction on osteoarthritis patients than rheumatoid arthritis patients. Tai-Chi for arthritis 12 form was an appropriate intensity exercise for osteoarthritis patients.

In this study, thermoplastic composites were manufactured using ABS(acrylonitrile butadiene styrene), PC(polycarbonate), and POE(polyolefin elastomer), which are thermoplastic plastics. Twin screw extruder and injection molding were used to manufacture thermoplastic composites. When the ABS/PC/POE thermoplastic composite material was manufactured, the POE mass fraction was set to 1 to 5 wt.%, and the thermal and mechanical properties according to the POE mass fraction were analyzed. Based on the physical properties of ABS/PC/POE, a 3D model in the form of an e-bike frame was created. After setting the boundary conditions, when an external load is applied, geometry simulation was performed to predict product performance. The ABS/PC/POE thermoplastic composite material exhibited the best physical properties when the mass fraction of POE was 3 wt.%. In the simulation results for the physical properties of the 3D model in the form of an e-bike frame, the best physical properties were shown when the mass fraction of POE was 2 ~ 3 wt.%. As a result, the manufacturing conditions for ABS/PC/POE thermoplastic composite materials were set, and research was conducted to reduce product development costs and development time.

PURPOSE: This study examined the awareness and demands for Women's Health Physical Therapy (WHPT) of university students majoring in physical therapy. METHODS: From September to October 2020, questionnaire surveys were distributed to students majoring in physical therapy using a convenience sampling method. Data were collected via an internet form from 300 students in eight universities. The survey consisted of three parts consisting of five general characteristics, four questions for awareness, and five questions for the demands. The numerical values for the questions were calculated using a Likert-type scale and descriptive statistics. An independent T-test, ANOVA, and Dunnett T3 test were performed, and the significance level was .05. RESULTS: The demands (3.88) level of the WHPT was higher than the awareness (2.32). The awareness was similar in both genders (p > .05), but there was a significant difference in the demand between genders (p < .05). Female students knew better and had more demands of WHPT than male students. Similarly, a difference in the awareness level by grade was found. The 4^th grade had the highest awareness comparing the 1^st, 2^nd, and 3^rd grades, but there was no significant difference in awareness and demand according to clinical practice (p > .05). CONCLUSION: The students have high demands compared to awareness, suggesting that the university and association need to prepare diverse and deeper education on WHPT.

The last decade of this centry is now the accepted birth date of that sub-discipline of pharmacy that is now called 'biopharmceutics'. Wagner defines biopharmaceutics 'as the study of the influence of fomulation on the therapeutic activity of a drug product.' More specifically, he states that biopharmaceutics encompasses the study of the relationship between the nature and intensity of the biological effects observed in animals or man and the following factors: 1. The nature of the form of the drug (ester, salt, complex, etc). 2. The physical state, particle size, and surface area. 3. Presence or absence of adjuvants with the drug. 4. The type of dosage form in which the drug is administered. 5. The pharmaceutical process (es) used to make the dosage form. The philosophy inherent in this definition has revolutionized our thinking with respect to product development, quality control, and to the practice of pharmacy itself. Althoughthe the emphasis herein will be on quality control, the interrelationship between this and the other areas of pharmacy will be evident. The principles of quality control dictate that a wide variety of techniques be used to evaluate the quality of a dosage form. Since quality must be built into a dosage form, the pharmaceutical scientist begins the process at the research stage, continues it during the production stage, and ends it by applying the tests and procedures established by parmacopeial commissions. These stages are usually separate and distinct and, because of this, product quality has become synonymous with compliance with pharmacopeial specifications.

In this study, the ex-formal expressions observed in space form of Korean modern architecture are distributed for characteristic analysis based on the period and type. The result of the study is certified by the work analysis and the result is as follows. Initially, due to the limited materials and influence of western brutalism, the works developed during 1960~70 tend to be plastic and contain expressionism. Around 1980's, the works tend to show forms of amusement and popularity. In 1990's the works show significance in deconstructive expression. From after 2000, ecological concept of architecture was introduced and organic expression started increasing Secondly, the ex-formal expressions are found to be in four different types. The organic expression is shown regardless of the period. In modern days, not only the physical properties of materials, but also the ecological concept is combined with the organic expression and is in increase. The plural expression started appearing after the 1980's and the sculptural diversity is enhancing with the addition of decorative factors or modification of geometrical form. The ex-construction and deconstructive expression show significance in some characteristics such as folding, inclination, and geometrical explosion. The free form and nonlinear expression tend to increase dramatically based on the development of structure technology as well as execution and introduce of the digital design technique.

In this paper, I tried to interpretate the matter and form of Chumsungdae, which has been mainly assumed as an facility for astronomical observaton of ancient Shilla dynasty, located on Kyongju, Korea. Basically, I took the thoughts of the place and the theory of cognition on landscape as a research tool, and the research was undertaken through the surveying the physical surroundings of chumsungdae and studying the references related to a myth, thoughts, and a tale of shilla era. This research was anticipated to find out the various symbolic meanings and functions of Chumsungdae and its place, which is somewhat different from the view of scientific uses of it. The matter and form of the Chumsungdae realizes the archetypal form of the well and meanings of petition for agricultural abundance, leading to a wishing for political stability of the nation, especially an authority of a reign of the queen, named Sun-duk who is the first one in Shilla Dynasty. The chumsungdae was located on the very sacred place surrounded by the tumulous and Kyerim forest which was birth and death place of the founder and king of a family of Kim. It does mean that the Chumsungdae was very scared work, and made place with combination of meaning above mentioned and natural environment. Finally, this paper suggested the neighboring area of the Chumsungdae be restored with the forest as an archetypeof old picture and environment of Kyerim.
