Background: Percutaneous coronary intervention (PCI) has been established as one of the effective therapeutic methods in the treatment of ischemic heart disease. A coronary artery stent is the most promising device in PCI, however in-stent restenosis (ISR) remains a major problem to be overcome. Methods: Follow-up coronary angiograms (CAG) three times after stenting were performed in 107 out of 3,816 stented patients at Chonnam National University Hospital between August 1992 and July 2004. The patients were divided into four groups: forty eight patients (Group I: 58.7±9.5 years, 35 Males) had no incident ISR on three follow-up CAG. Fourteen patients had three times of ISR and underwent four PCIs (Group II : 54.5±9.51 years, 12 Males), 15 had two times of ISR and underwent three PCIs (Group III : 53.9±5.9 years, 11 males), 30 had one time of ISR and underwent two PCIs (Group IV : 59.6±9.5 years, 27 males). Each group was analysed according to clinical characteristics, coronary angiographic findings, and therapeutic modalities for ISR. Results: There was no differences in clinical diagnosis, lesion location, multi-vessel lesion and TIMI flow. Risk factors for atherosclerosis were not different except for diabetes mellitus. The incidence of diabetes mellitus was more common in Group II than in Group I (Group I: 22%, Group II: 57%, Group III: 46%, Group IV: 20%, Group I vs. Group II: p =0.023). Stent length and diameter were not different among four groups. Conclusion: The only predictor of recurrent coronary stent restenosis more than three times is diabetes mellitus.

To evaluate the effect of dried barley sprout powder on muffins, muffins were made after they had been supplemented with barley sprout powder (0, 10, 20 and 30%(all w/w)). Moisture content, crude protein and crude lipid was reduced with an increase in barley sprout powder. The content of crude ash and crude fiber in the control group was significantly lower than those of the samples with barley sprout powder. The pH in the sample with barley sprout powder was lower than that of the control group. The highest specific gravity in the group with 30% of barley sprout powder was 0.84. No significant weight and baking loss rate changes were observed. The sample with no barley sprout powder showed the highest volume. The sample with 30% of barley sprout powder showed the highest uniformity. In color, the L-value and a-value of the control group were significantly higher than those of the other groups. Hardness, gumminess and chewiness of the control group showed the lowest value rather than the other groups. Springness and cohesiveness of the control group were significantly higher than those of the other groups. Crumb color, grass odor and bitter taste showed significant difference among groups. Acceptance of appearance, flavor, taste and total acceptability of groups with 10% and 20% of barley sprout powder did not showed any significant difference when compared to the control group. Based on the above results, less than 20% of barley sprout powder would be proper to make muffins.

The primary purpose of this study was to determine the reliability of lumbar flexion and extension range-of -motion measurements obtained with the modified -modified $Sch{\ddot{o}}ber$ methods on normal and subjects with low back pain. Sixty two, aged 20 to 30 years(x = 22.0, SD = 2.07), with normal and twenty two, aged 14 to 66 years(x = 35.6, SD = 15.88) with chronic low back pain were measured by two physical therapist with 3 to 10 years (x = 6.5) of clinical experience. The therapist used the modified-modified $Sch{\ddot{o}}ber$(MMS) techniques to measure, in random order and on two occasions, the subjects' lumbar flexion and extension. For therapist 1, Intraclass correlation coefficients(ICC) for test-retest reliability for normal varied .9923, .8802(flexion, extension). and low back pain pateint varied .9950, .9313(flexion, extension). For therapist 2. ICC. for test-retest reliability for normal varied .9903, .8921(flexion, extension). and low back pain pateint varied .9843, .9551(flexion, extension). Interrater reliability for normal varied .9477, .6960(flexion, extension) and low back pain pateint varied. 9776, .7576(flexion, extension). Thus the MMS. method appears to be a reliable method for normal and patient with low back pain.

Purpose: The purpose of this study is to suggest new strategies available for the physical therapy curriculum development. Method: The curriculum of 4 Universities in 4 countries; America, Australia, Canada and Korea was compared to suggest new curriculum. Results: Overall, curriculum in Korea emphasized skill and technique areas and didn't showed many subjects to take foundation of subject for understanding principles. The experience in clinic is not enough to satisfy international recommendation. Conclusion: We suggest that a new curriculum should be based on the three part which are foundation, essential and selection subject, and extended clinical experience to essentially need to be physical therapy in the world-standard.

고령층의 사망원인 중 높은 비율을 차지하고 있는 뇌졸중, 심장질환은 갑작스럽게 발생하여 사망에 이를 수 있으므로 조기 진단하여 지속적인 관리가 필요하다. 고위험성 질병을 진단하기 위해서는 의료 영상을 이용한 의료진 판독을 통해서 수행되어야 하지만 판독 시간이 많이 소요되거나 의료진에 따라 판독 의견이 달라지는 경우가 발생하고 있다. 본 연구에서는 뇌졸중의 주요 원인인 대동맥 동맥경화성 플라크 상태를 분류하고 영역을 예측할 수 있는 컨볼루션 오토인코더(convolution autoencoder)와 유넷(U-Net) 모델을 수립하여 판독 시간을 단축시키고 정확도를 높이고자 한다. Stroke and heart disease, which account for a high percentage of the causes of death amongst the elderly population, can occur suddenly leading to death. Hence, early diagnoses and continuous management are required. High-risk diseases should be diagnosed through medical personnel using established medical techniques. However, it is time consuming to decide on a diagnosis or the opinion may differ depending on the medical professional. This study aims to shorten the diagnosis period and provide high accuracy diagnoses by establishing the semi-supervised convolution autoencoder and the U-Net models that can classify aortic atherosclerotic plaque conditions and predict the primary locations for stroke occurrence.

The purposes of this study were 1) to examine the effects of microcurrent electrical neuromuscular stimulation 2) to compare surface electrode with needle electrode at somatic acupuncture points on experimental pain threshold measured at the distal end of the radius 3) to determine the changes in effect over time. A total of sixty healthy adult male and female subjects were assigned randomly to one of two experimental group or to a control group. Group 1(n=20) received MENS(Microcurrent Electrical Neuromuscular Stimulation) with surface electrode. Group 2(n=20) received MENS with needle electrode. Group 3(n=20) received no MENS. It measured experimental pain threshold at the wrist on pretreatment, 0 min after treatment. 15 min after treatment, 30 min after treatment in two experimental group. The results were as follows: 1. Experimental pain thresholds were higher ire males than females(P$lt;0.01). 2. Only the experimental group exhibited a significant increased in pain threshold after MENS treatment(P$lt;0.05). 3. Surface electrode group increased significant pain threshold 0 min, 15 min after treatment, but greatly decrease 30 min after treatment. 4. Needle electrode group increased significant pain threshold 0 min, 15 min after treatment, but decrease 30 min after treatment. The results suggest that MENS applied to appropriate somatic acupuncture point can increase pain threshold. Further research is needed to assess, the effects of greatly variety intensity of MENS of pain sufferes.
