Most of the Medical Junior Colleges faced new environmental changes: School years of some Health-related departments were extended from two-year program to three-year ones; The total high school graduates willing to apply to the colleges will fall short of the legal number limits of this country; Govorment's educational opening policies enables competitive foreign schools to land in our country more easily. In order to survive under these turbulant circumstances, any junior college has to cultivate it's own competitiveness establishing strategies and utilizing resources very efficiently. Some of the major points extracted from three-year junior college professors' opinions against the environmental changes are as follows, 1. Environmental changes should be fully appreciated. And junior colleges have to make haste to establish strategies placing priorities on specific fields which are their own strengths compared to others. 2. The crieria of provisions of miminstry of Education on the facilities and equipments should be enhanced. 3. The practical way to use available resources effectively is to make the best of human resources. 4. It is time to consider consolidating akin departments to one. 5. The school year of the health-related departments should be extended to four years to meet the contemporary needs in the medical fields.

This study was to measure whether single axis foot or the SACH foot applied to below-knee amputation patients would bring positive changes to the patients' cardiopulmonary function, and help them to overcome their disability. The experiment took place at Asan Medical Center, University of Ulsan, from July 20th to November 20th, 1999 with 10 below-knee amputation patients. The patients were asked to equip single axis foot and SACH foot by turns and lead them to walk on a treadmill which was designed to increase its steep slope. Patients heart rate and blood pressure were recorded before and after their walking, The heart rate, systolic blood pressure, diastolic blood pressure of the patients who were equipped with, either SACH foot or single axis foot, have been increased with as the slant becoming steeper. The heart rates during the experiment did not show relevant changes according to the kind of foot used and the gradient, but the changes occurred before and after the walking(p=0.0001), The similar result of systolic blood pressure was found during the waking(p=0.01). Below-knee amputation patients are expected to walk and perform the routines better, no matter what type of foot is used, as long as they wear an artificial foot properly and taking features of foot product into consideration

Background: The purpose of this study was to identify the effects of cervical manipulation for improve blood velocity and flow in the subjects with asymmetric vertebral artery. Methods: Twenty-four subjects on asymmetric vertebral artery with right side have less blood flow than left side participated in this study for apply to non-specific cervical manipulation on lower portion. Measurement method were using duplex ultrasound with colour doppler imaging for blood velocity and flow on left and right vertebral artery. Results: Compared changes of blood velocity and flow on unilateral after the cervical manipulation, the left blood velocity decreased significantly (p<.01) and the right blood velocity increased significantly (p<.01). The left blood flow no significant changes and the right blood flow increased significantly (p<.01). Compared changes of blood velocity and flow on bilateral, the left and right blood velocity and flow made significantly difference on pre-manipulation (p<.01). However, both side no significantly difference on post-manipulation. Conclusions: These findings suggest that the non-specific cervical manipulation took effect for improve blood velocity and flow in the subjects with asymmetric vertebral artery. Therefore, therapeutic approaches for improve to asymmetric vertebral artery should be consider non-specific cervical manipulation.

The spinal cord is highly complex, consisting of a specialized neural network that comprised both neuronal and non-neuronal cells. Any kind of injury and/or insult to the spinal cord leads to a series of damaging events resulting in motor and/or sensory deficits below the level of injury. As a result, muscle paralysis (or paresis) leading to muscle atrophy or shrinking of the muscle along with changes in muscle fiber type, and contractile properties have been observed. Traditionally, histology had been used as a gold standard to characterize spinal cord injury (SCI)-induced adaptation in spinal cord and skeletal muscle. However, histology measurements is invasive and cannot be used for longitudinal analysis. Therefore, the use of conventional magnetic resonance imaging (MRI) is promoted to be used as an alternative non-invasive method, which allows the repeated measurements over time and secures the safety against radiation by using radiofrequency pulse. Currently, many of pathological changes and adaptations occurring after SCI can be measured by MRI methods, specifically 3-dimensional MRI with the advanced diffusion tensor imaging technique. Both techniques have shown to be sensitive in measuring morphological and structural changes in skeletal muscle and the spinal cord.

The purpose of this study was to analyze the changes of the muscle strength and length according to the changes of evaluation postures. Subjects of this study were 13 male and 13 female students. 6 evaluation postures were selected for this study(K90H90, K90H45, K90H0, K70H90, K70H45, K70H0 ; K90=knee $90^{\circ}$ flexion, K70=knee $70^{\circ}$ flexion, H90=hip $90^{\circ}$ fleion, H45=hip $45\circ}$ flexion. H0=hip $0^{\circ}$ ). The peak torque and hamstring muscle length(from fibula head to ischial tuberosity) were measured at each postures. The peak torque level was evaluated by make use of the KIN-COM. The results were as follows : 1. The peak torque in male was significantly increased with changes of hip flexion angle but not in female(($90^{\circ}\;>\;45^{\circ}\;>0^{\circ}$). 2. The hamstring length and peat torque in male and female was significantly changed according to the alteration of evaluation postures.

We selected 100% cotton fabric, 100% Hanji yarn fabric and two kinds of cotton / Hanji yarn blended fabrics and fused them with three kinds of interlinings in order to examine changes to the physical properties and the post-adhesion physical properties of Hanji yarn blended fabrics. Changes in KES values were examined after fusing. First, EM, B, 2HB, MMD values of Hanji yarn blended fabrics were higher than cotton fabric, and LT, RT, G, 2HG, LC, WC values of cotton fabric were higher than Hanji yarn blended fabrics. Tensile recovery was lowered, bending stiffness was increased, and shear stiffness was lowered when Hanji yarn was mixed. Second, the KES value of LT, B, 2HB, G, 2HG, LC, WC increased after fusing, while the EM, MMD values decreased. SMD was shown to decrease or increase depending on the type of fabric. The adhesive effect on bending stiffness and shear stiffness due to the mixing of Hanji shows a different tendency in the comparison of α_B and α_G.

Purpose : The purpose of this study was to investigate characteristics of the forced pulmonary function test effect by changes in lung function related to postures and by Transverse Abdominis(TrA). Contraction in standing position during forced inspiration and expiration with young female adults. Methods : 10 young female adults were recruited this study. pulmonary Function test was measured with a Master-screen Body (VIASYS Inc., CA, 미국). To check the changes in lung function with different postures, we tested pulmonary function in the standing and supine position each. In the standing position, while the transversus abdominis was activating, we compared the forced inspiration with the forced expiration. Statistical analysis was used Independent t-test to know difference between forced inspiration and expiration of activated TrA. Results : According to the study, the change of pulmonary function were statistically significant difference in the standing compared to the supine position. The contraction of the transversus abdominis causes decrease in the change of forced inspiration and increase in the change of forced expiration. Conclusion : These results indicate that spontaneous contraction of the TrA in standing position helps pulmonary function. And the selective contraction of the transversus abdominis at the end of forced inspiration makes increases in the forced expiration.

This study, based on physical therapy interventions for menstruation disorders, observed the effect of Pilates stabilization exercises and Kinesio taping on dysmenorrhea and prostaglandin $F2{\alpha}$ levels. Female college students (n=37) who had >70 points on the mood disorder questionnaire (MDQ) and >4 points on the visual analogue scale (VAS) were divided into three different groups, the Pilates group (PG, n= 13), Pilates and Taping group (PTG, n=12), Taping group (TG, n=12). Pilates and taping were performed 3 times a week for 6 weeks. Pre- and post-menstruation difficulties were measured through the MDQ. Changes in blood prostaglandin $F2{\alpha}$ levels were also measured. Changes in pre- and post-menstrual pain and prostaglandin $F2{\alpha}$ levels were significantly reduced in the PG, PTG, and TG. Changes in pre- and post-menstrual pain and prostaglandin $F2{\alpha}$ levels resulted in significant differences in the PTG and TG. Dysmenorrhea and prostaglandin $F2{\alpha}$ levels were significantly decreased in the TG than in the PTG. These findings suggest that Pilates stabilization exercises and Kinesio taping are effective in decreasing menstrual difficulties and pain in female college students.

PURPOSE: Selective strengthening of the transverse abdominis muscle (TrA) during abdominal hollowing makes an important contribution to the stability and control of the spine. This study examined the effects of abdominal hollowing exercise (AHE) according to the visual feedback method on the external oblique, internal oblique, and transverse abdominis muscles. METHODS: Twenty healthy subjects were assigned randomly to an AHE with visual feedback from real-time ultrasound image (group A, n = 10), AHE with visual feedback with pressure biofeedback unit (group B, n = 10). Both groups underwent 20 min of AHE with visual feedback once daily, five days/week for two weeks. The changes in the muscle thickness of the TrA, internal oblique abdominal muscle (IO), and external oblique abdominal muscle (EO) were measured by ultrasonography. RESULTS: The thickness of TrA was changed significantly in both groups (p < .05). However, the lowest minimal detectable changes were achieved in Group A. The thickness of the IO and EO muscles in group A was changed significantly, but there were no significant changes in group B. CONCLUSION: Both visual feedback methods were effective for strengthening the TrA muscles selectively. Nevertheless, AHE with visual feedback using real-time ultrasound images may be more useful in trA muscle contraction.
