This study, a quasi-experimental study using a nonequivalent control group pretest-posttest design. conducted a survey on 30 patients test group and control group of IS patients sampling an adjacent population at random - who are operated on the breast cancer and are in the A University Hospital located in Suwon, to examine into the effects of foot reflex zone massage on their pain and sleep satisfaction through the nursing interventions. It gave them a foot reflex zone massage for the total 30 minutes-basic massage 10 minutes and reflex massage 20 minutes required to alleviate their pain day in day out covering a two-month period from the first of July to the first of September 2004. for the purpose of collecting data. It launched into a two-round foot reflex zone massage at 6 and 24 hours since mastectomy through a direct visit at the hospital room to measure pain intensity, physiological index(pulse and blood pressure) and sleep satisfaction of them. The results are as follows. First, it showed that there is all the difference between pain intensity of test group and that of control group. In result, the first hypothesis, pain of test group. which measure at 6(p=.000) and 24 hours(p=.001) since mastectomies, will be bigger than that of control group, was established. Second, it showed that there is all the difference between physiological index of test group and that of control group. In result. the second hypothesis, pulse(p= .025, p= .002), systolic blood pressure(p= .004, p=.012) and diastolic blood pressure(p=.004. p= .003) of test group, which investigate at 6 and 24 hours since mastectomies, will be bigger than that of control group, was established. Third, it showed that there is a significant difference between sleep satisfaction of test group and that of control group(p=.000). In result, the fourth hypothesis, sleep satisfaction of test group. which examine in the morning after mastectomies, will be bigger than that of control group, was established. In the result. a foot reflex zone massage is seen to be effective in the pain reduction and sleep promotion of patients who are operated on breast cancer, and in providing them with more qualitative care by improving confidence between them and nurses through a physical touch. Also, it can be applied to a clinical examination through an independent nursing intervention.

Among several movements that occurred upon a slope, golf swing is the most typical one because environmental conditions dynamically vary with many kinds of slopes. Some studies on the golf swing were performed about a weight transfer on flatland, however, there couldn't be seen any study about the weight transfer on slope elsewhere. Therefore, the purpose of this study was to provide quantified data to objectively test the coaching words and keys about the weight transfer at sidehill slope during goal impact EspeciaIly sidehill Slopes with ball above the feet. Four highschool golfer, who have average handy 5, were recruited for this study. Plantar pressure distribution and cinematographic data were collected during golf swing in the conditions of flatland, $5^{\circ}$, $10^{\circ}$ and $15^{\circ}$sidehill slope simultaneously. The two data were used to synchronize the two data later. The plantar regions under the foot were divided into 8 regions according to the directly applied pressure pattern of the subject to insole sensor. The 8 foot regions were hullux, medial forefoot, central forefoot, lateral forefoot, medial midfoot, lateral midfoot, medial heel, and lateral heel. And the plantar pressure data was also divided into four movement address, phases-backswing. downswing, and follow-through phases according to the percentage shown to the visual information of film data. Based on the investigations on public golf books and experiences of golfers, it was hypothesized by the authors in the early of this study that the steeper slopes are, the more weight loads on left foot that positions at the higher place. When observing the results of plantar pressure and vertical force curves according to the sidehill slope conditions, the hypothesis could be accepted.

The purpose of this study was to analyze biomechanical factors of trail running shoes applied to korean shoe-lasts. 10 healthy male subjects with an average age of 37.2 years(SD=8.28), weight of 69.6 kg(SD=10.56) and a height of 171 cm(SD=4.93) were recruited for this study. Ten males walked on a treadmill wearing four different shoes. Foot pressure data was collected using a Pedar-X mobile system(Novel Gmbh., Germany) operating at the 1000 Hz. Surface EMG signals for tibialis anterior, gastrocnemius, vastus lateralis and biceps femoris were acquired at 1000 Hz using Noraxon TeleMyo DTS system(Noraxon Inc., USA). Foot pressure and leg muscle fatigue were measured and calculated during walking. The results are as follows: After walking 60 minutes, Type A showed a lower MPF. MPF values were significantly different from each muscle(p<.05). Therefore, Type A shoe might decrease muscle fatigue in the legs while walking. In addition, Type It showed that Type A shoe has the highest contact area and the lowest maximum pressure. As a result of the analysis, Trail running shoes will use a new design to reduce muscle fatigue and are expected to increase comfort and fitting.

Pressure sores are an ulceration and necrosis of the skin and underlying tissue usually occur after prolonged or repeated pressure by interruption of blood flow from the small. vessels to the skin and deep tissue. The management of pressure sores is mostly difficult and requires prolonged hospitalization or repeated surgical interventions with a high recurrence rate. In this article we reviewed 14 cases of National Pressure Ulcer Advisory Pannel staging III, IV over the lateral malleolar area of the ankle in 2 years period from January 1999 to October 2001. The pressure over lateral malleolar area was mainly due to unique Korean sitting position with cross legs at flexed hips and knees or supine position of patient with external rotation of low extremity. Male to female ratio was 11: 3 and ages were between 36 and 83 (mean age: 67.1 years). Associated diseases were DM(7 cases), Hemiparesis caused by CVA(2 cases), Liver cirrhosis(2 cases), disarticulation of opposite hip due to squamous cell ca.(1 case), Intertrochanteric Fx.(1 case). Wound cultures reported Staphylococus, Pseudomonas and others. Abnormally elevated ESR and CRP were seen in 6 cases. Operative treatments were irrigation and debridement, direct closure with gravity drainage and skin grafting. The most important aspect of pressure sore treatment is pressure relief of the lateral malleolar area. Pressure-relieving Cast or Brace was helpful for local management and preventing recurrence.

Shake table tests were conducted on scaled tunnel model to investigate the mechanism and effect of seismic loadings on horseshoe scaled tunnel model in ground fissure site. Key technical details of the experimental test were set up, including similarity relations, boundary conditions, sensor layout, modelling methods were presented. Synthetic waves and El Centro waves were adopted as the input earthquake waves. Results measured from hanging wall and foot wall were compared and analyzed. It is found that the seismic loadings increased the subsidence of hanging wall and lead to the appearance and propagation of cracks. The values of acceleration, earth pressure and strain were greater in the hanging wall than those in the foot wall. The tunnel exhibited the greatest earth pressure on right and left arches, however, the earth pressure on the crown of arch is the second largest and the inverted arch has the least earth pressure in the same tunnel section. Therefore, the effect of the hanging wall on the seismic performance of metro tunnel in earth fissure ground should be considered in the seismic design.

Background: The flexible flatfoot is characterized by a flattening of the foot arch due to excessive bodyweight. The use of shoe insoles or taping methods has been identified as effective in realigning the navicular or calcaneus bones and addressing supination in pronated feet. Objects: This study aimed to analyze the difference between the arch taping attachment method, introduced in a previous study, and a novel taping method designed to provide support to the inner aspect of the heel bone in cases of flexible flatfoot. Methods: A navicular drop test was performed to discriminate flexible flatfoot. To analyze the differences in pressure distribution during walking for each taping method, the subjects underwent testing in the barefoot state with no attachments. The procedure included a sequence of arch taping and heel taping. Subsequent analysis of pressure distribution during walking utilized the GaitRite^® system (GAITRite Gold, CIR Systems Inc.). Results: Arch taping and calcaneus taping significantly reduced the integrated pressure over time and peak pressure on the medial side of the midfoot for both feet compared to the barefoot state. Conclusion: The findings of this study suggest that supporting the inside of the heel through calcaneus taping, without direct stimulation to the longitudinal arch and navicular bone, is an effective intervention for flexible flatfoot.
