본 논문에서는 도로 혹은 철도 분야 옹벽 시공에 많이 적용되는 Back-to-Back (BTB) 옹벽 형태의 보강토 옹벽의 하중 지지 특성을 다루었다. 이를 위해 FHWA 설계 기준에서 구분하고 있는 두 가지 시공 조건에 대한 모형 보강토 옹벽을 구축하고 보강재 포설길이를 주 변수로 하여 상부에 상재하중을 파괴 시까지 재하하는 방법으로 다양한 조건에 대한 모형실험을 수행하였다. 실험 결과에 대한 분석 결과 좌 우 옹벽의 보강재가 중첩되지 않는 시공 조건의 경우 보강재의 길이에 따른 옹벽의 거동이 일반옹벽과 유사한 거동을 보이는 것으로 나타났으나 보강재의 길이가 중첩되는 경우에는 보강재의 길이에 따른 변화가 그다지 크지 않으며 보강재의 길이에 있어서 퐁벽높이 대비 50% 이하의 경우 하중지지력이 현저히 감소하는 것으로 나타났다.

Purpose: The strength of hand grip, low back muscles and knee joint muscles were measured and then compared to the bone mineral density (BMD) of each forearm bones (including ulna and radius), lumbar spine, and femur in young women in order to identify the relationship between muscle strength and bone mineral density. Method: The BMD was measured with a Dual Energy X-ray Absorptiometry and muscle strength was measured with a handgrip dynamometer and a Cybex Norm. Data were analyzed with frequencies, percentages, means, and Pearson correlation coefficients. Result: 1) Higher grip strength correlated positively with higher BMD in the forearm (r=.246, p=.007), higher low back extensor strength with higher BMD in the femur (neck, trochanter and Ward's triangle)($r=.323{\sim}.226$, $p=.003{\sim}.043$) and higher strength in the knee joint extensor with higher BMD in the lumbar spine (r=.227, p=.041), femur neck, and femur trochanter significantly ($r=.295{\sim}.226$, $p=.007{\sim}.043$). There was no significant correlation between the strength of low back extensors and BMD in the lumbar spine, now with strength of knee joint flexor and the BMD in the femur. 2) The muscle strength of each part of the body had significant positive correlations to each other part ($r=.255{\sim}.728$ $p=.021{\sim}.000$) Conclusion: The results of this study showed that with the development of a muscle there was an increased BMD of the corresponding part, and the BMD of each part was influenced by adjacent muscles. To promote the health of bones, it is important to strengthen the muscles of related bones, based on balanced development of all muscles.

Purpose: The purpose of this study was to identify the effects of hand acupuncture on relieving of abdominal pain. Method: Fifty-five middle school students who complained abdominal pain were selected as subjects. There were 35 students in the experimental group while 20 students were in the control group. Convenience assignment was used. The experimental group received hand acupuncture treatment which was to puncture corresponding points (epigastric pain A8, A12, A16, K9, F4, E42; lower abdominal pain A1, A4, A6, A8, J1, H2) on both the palm and the back of a hand with disposable acupuncture needles, and then to remove them after a 20-30min. recess during the subjects was in supine position on a bed. Result: Degree of subjective pain decreased statistically in the experimental as compared to the control group. No statistical significant differences were found in objective pain and comfort between experimental and control group. Conclusion: These findings indicate that hand acupuncture is an effective method for reducing abdominal pain. Therefore, hand acupuncture could be considered as an independent nursing intervention for abdominal pain reduction.

Back pains include pain in one or both side costa portion and lateral abdomen. There are different kinds of flank-related disease such as intercostal nerve pain, chronic gastritis, duodenitis, herpes zoster, pepticulcer, cholecystitis, cholelithiasis and so on. Back pain arises from pathological abnormal activities. On the other hand psychogenic pains are caused by psychogenic factors without pathological abnormal activities. This is similar to KiWol back pain, which resulted from psychogenic factors like stress, anxiety, anger and etc. In oriental medicine, KiWol is the state of depression of Ki, and Shihosogansan used to treat the back pain diagnosed as stagnation of the liver Ki. So, we decided to apply Shihosogansan to a patient who suffered from back pain diagnosed as stagnation of the liver Ki. Therefore the patient treated with Shihosogansan and improved in consciousness symptoms, so we report it for the better treatment.

Objectives : This study was designed to investigate the correlation coefficients among Oswestry low-back pain disability index(ODI), Roland-Morris disability questionnaire (RMD), visual analogue scale(VAS), lumbar lordosis angle(LLA), Cobb's angle and Ferguson's angle(FA). Methods : We measured LLA, Cobb's angle, and FA of 42 students. Then we researched ODI, RMD and VAS of all students, and analyzed correlations coefficient among all of them. Results : 1. There was significant correlation among VAS, RMD, ODI. 2. There was significant correlation between ODI and Cobb's angle. 3. There was no significant correlation between LLA, FA, Cobb's angle and VAS. 4. There was no significant correlation among LLA, FA, Cobb's angle and RMD. Conclusions : According to above results, there was no significant correlation between lumbosacral balance and low back pain except between ODI and Cobb's angle. On the other hand, there was significant correlation among RMD, ODI and VAS.

Purpose: The purpose of this study was to identify the effect of exercise therapy on low back pain, self-urination disorder, bleeding, and hematoma in Percutaneous Coronary Intervention (PCI) patients. Methods: A total of 64 PCI patients were recruited from C hospital located in C city, from June until August of 2010. The patients were divided into two groups as the exercise and control group. Thirty-two participants in the exercise group took bedrest for two hours after PCI, and then received excise therapy. The other 32 participants in the control group took the usual 8-hour bedrest with intermittent back care by the unit nurses. Results: In the relieving effect of low back pain, exercise group reported pain reduced faster than the control group. On the other hand, there were no significant differences between the two groups in alleviant of self-urination disorder, bleeding, and hematoma. Conclusion: Exercise therapy for reducing patients' low back pain showed to be an effective nursing intervention. Since there was no bleeding or hematoma after PCI in the exercise group, this study provided the ground suggesting that it might be possible to reduce the bedrest time after PCI without increased risk of bleeding or hematoma.

The purpose of this study was to review the relevant literature about coaching and thereupon, survey the coaching methods used for golfer lesson to reinterpret them and thereby, describe in view of kinetics the swing errors committed frequently by amateur golfers and suggest more scientific golfer coaching methods. For this purpose, kinetic elements were divided into precision and power ones and therewith, the variables affecting such elements were identified. On the other hand, swings were divided into address, take-back, back-swing, back-swing top, down-swing, impact and follow-through to determine 20 variables for each form and thereby, define their errors to determine the relations between their frequency and errors. For this study, a total of 60 amateur golfer were sampled, and their swing forms were photographed with two high-speed digital cameras, and the resultant images were analyzed to determine the errors of each form kinetically, which would be analyzed again with the program V1-5000. The results of this study can be summarized as follows; The kinetic elements could be identified as precision, power and precise power. Thus, setup and trajectory were classified into precision elements, while differences of inter-joint angles, cocking and delayed hitting. Lastly, timing and axial movement were classified into precise power elements. Three errors were identified in association with setup. The errors related with trajectory elements accounted for most (7) of the 20 errors. Three errors were determined for inter-joint angle differences, and one error was associated with cocking and delayed hitting. Lastly, one error was classified into timing error, while five errors were associated with axial movement. Finally, as a result of arranging the errors into a cross table, it was found that the errors were associated with each other between take-back and back-swing, take-back and follow-through, back-swing and back-swing top, and between back-swing and down-swing. Namely, an error would lead to other error repeatedly. So, it is more effective to identify all the errors for every form and correct them comprehensively rather than single out the errors and correct them one by one.

Mainly through the pervasive emergence of portable devices (laptops, PDAs, now iPods), the screen arts, that is, the cinematic arts has suffered the loss of what constitutes the core of its existence: the theatre and theatre-audience. This paper discusses cinema's distinct place and significance in culture and its difference from television and other forms of mass media. The most pressing question at hand would be, "how do you bring back attention to the medium that is distinctly cinematic?" "How do you bring people back to the theatres?" This paper argues that cinema, and the film industry as a whole must push for a technological leap that is in conjunction with culture. With mentioning of the rapid development of 3D technologies in the moving images, this paper proposes that such technological novelties and innovation are necessary conditions for a new kind of film culture to emerge.

In order to clear the basic concept about oriental medical physiology and pathology, We studied the theory of three yin, three yang, and it is based on the principle that yang goes forward and yin goes back. The result were summarized as follows. 1. It showed how to originate about the concept of three yin three yang. 2. It showed the logical basis concerning that the TAIYANG channels are open, the YANGMING channels are shut, the SHAOYANG channels are pivots, the TAIYIN open, SHAOYIN shut, JUEYIN pivots. 3. According to the opening, closing, pivoting principle, It explained the exterior and interior relation such as TAIYANG and SHAOYIN, YANGMING and TAIYIN, SHAOYANG and JUEYIN. 4. According to the opening, closing, pivoting principle, It showed that arteries of the twelve channels rotated in lung channel of hand-TAIYIN, the large intestine channel of hand-YANGMING, the stomach channel of foot-YANGMING, the spleen channel of foot-TAIYIN, the heart channel of hand-SHAOYIN, the small intestine channel of hand-SHAOYANG, the urinary bladder channel of foot-TAIYANG, the kidney channel of foot-SHAOYIN, the pericardium channel of hand-JUEYIN, the sanjiao(三焦) channel of hand-SHAOYANG, the gall bladder channel of foot-SHAOYANG, the liver channel of foot-JUEYIN. 5. As arteries of the twelve channels was based on the cycle, the logical criticism about Napgibup(納氣法) was shown.
