Hot gas path components, which are made of nickel based superalloys, are subject to periodic replacement due to degradation of thermomechanical properties that might bring catastrophic failure during normal operation of gas turbine units. In order to rejuvenate the metallurgical condition of the serviced components, heat treating techniques such as solution annealing and aging heat treatments have widely been employed. However, the effectiveness of those typical heat treatments is not apparent enough in terms of quantitative grounds. On the other hand the demand of the rejuvenation heat treatment and hot isostatic pressing (HIP) have constantly been raised by the end users. Therefore it is necessary to verify how the typical heat treating techniques affect to the aged and degraded material. As the result of experimental work in this study, GTD-111 and GTD-222 Ni-based superalloys were collected and analyzed quantitatively through microscopic observation, microhardness evaluation and creep test.

The technique of AKA were devised and modified several times after clinical trials to obtain better result and were though to be few years ago. The published literatures on joint mobilization were unsatisfactory to me since the subject of treatment was not confined to the synovial joint and techniques seemed too violent to treat diseased joints. Among the techniques distraction gliding and the use of convex-concave rule by F. M. Kaltenborn were acceptable theoretically but they required considerable technical modification. By that time it was evident that pain in numerous painful conditions including organic regions could be eliminated by AKA new disease entitles such as aseptic arthritis of the sacroiliac joint, hip joint, shoulder joint, 1st costovertebral joint etc and periradiculitis were elucidated.

Objectives The purpose of this study was to investigate the relationship between the effects of acupuncture treatment and heart rate variability (HRV) in pre-menopausal obese women. Methods Thirty-seven obese women who met the inclusion criteria were recruited. To estimate the effects of acupuncture, obesity indices, such as body weight (BW), waist circumference (WC), hip circumference (HC), and the waist-hip ratio (WHR), were measured before and after the treatment. The HRV test was conducted before treatment and analyzed using the frequency domain method. Results The lnLF/HF ratio (natural logarithm of low frequency power/high frequency power ratio of the HRV value) before treatments was negatively correlated with differences in WC, HC, and WHR during treatment. The correlation coefficients between the lnLF/HF ratio and the differences in WC, HC, and WHR were r=-0.459 (p<0.01), r=-0.327 (p<0.05), and r=-0.339 (p<0.05) respectively. Conclusions As the baseline ratio of sympathetic activity to parasympathetic activity decreases, WC, HC, and WHR reduction significantly increased during treatment. Further study is needed to uncover the relationship between obesity-related variables and the autonomic nervous system to predict the effect of acupuncture.

The objective of this study is to investigate conservative treatment of pelvic fracture, and report that Korean rehabilitation treatment is effective for pelvic fracture. We reported a case about pelvic fracture treated with Korean rehabilitation treatment. We searched 10 domestic electronic databases to find reports on conservative treatment of pelvic fracture. We selected and analyzed 12 studies. In this case, pain, range of motion, and Oswestry Disability Index of patient were improved by Korean rehabilitation treatment. In analysis, traction, pelvic sling, hip spica cast, pelvic belt, medication are used in western medical treatment. Acupuncture, herbal medicine, cupping, moxibustion, physical therapy, manual therapy are used in Korean medical treatment. Most of conservative treatments are effective for pain, bone union, osteoporosis, dysfunction. In this study, we expect further study of Korean rehabilitation treatment program for pelvic fracture to compensate existing conservative treatment.

Objectives: Acupuncture treatment has been clinically used for functional recovery in Parkinson's disease. In the present study, we investigated the effect of acupuncture at Zusanli (ST36) on nigrostriatal dopaminergic neuronal cell death in rats. Methods: A Parkinson's disease model was induced by the unilateral injection of 6-hydroxydopamine (6-OHDA) into the striatum. Acupuncture treatment was performed at Zusanli (ST36) and at the hip, as a non-acupoint, once a day for 14 days. Two weeks after 6-0HDA injection, an apomorphine-induced rotational behavior test showed significant rotational asymmetry in rats with Parkinson's disease. Immunostaining for tyrosine hydroxylase demonstrated a dopaminergic neuronal loss in the substantia nigra and dopaminergic fiber loss in the striatum. Results: Acupuncture at the ST36 acupoint significantly inhibited rotational asymmetry in rats with Parkinson's disease, and also protected against 6-OHDA-induced nigrostriatal dopaminergic neuronal loss. These effects of acupuncture were not observed for non-acupoint acupuncture. Conclusions: The present study shows that acupuncture treatment, especially at the ST36 acupoint, can be used as a useful strategy for the treatment of Parkinson's disease.

Objectives : The purpose of this study is to report the effect of Korean medical treatment on a patient with relapsing transverse myelitis. Methods : The patient was treated using acupuncture, pharmacopuncture, herbal medicine and other treatments including moxibustion and therapeutic exercise for 8 weeks. We evaluated the patient's motor grade with medical research council(MRC) scale and evaluated active range of motion in the hip, knee, and anke joint. Results : Through treatment the patient's motor grade and active range of motion all improved. Other symptoms such as lower limb hypoesthesia and residual urine sensation also showed improvement. Conclusions : We concluded that Korean medicine treatment had respectable effect in improving symptoms on the patient with relapsing transverse myelitis.

Object : Waist circumference(WC), waist-hip ratio(WHR), waist-stature ratio(WSR), and body mass index(BMI) are commonly used for evaluating obesity. This Research were done to determine what is more sensitive obesity indexes(WC, WHR, WSR, BMI) Correlated with body composition such as body fat mass, body fat(%), visceral fat area, and fat free mass. And what is more sensitively correlated obesity indexes with % changes of body composition during weight reduction treatment. Methods : This clinical retrospective research were carried out 127 cases of female obese outpatients with weight reduction treatment during 1 month. Bioelectrical impedence analysis(for body composition) and body size(for anthropometric obesity indexes) were estimated in pre-treatment and post-treatment to evaluate the obesity indexes. Pearson correlation coefficients were used to select useful obesity index. Result & Conclusion : BMI is useful index for diagnosis and evaluation of obesity. WSR is sensitively correlated with visceral fat area and body fat(%). So, WSR is useful index for evaluating abdominal obesity and risk factors of metabolic syndrome. WC is correlated with both body fat mass and fat free mass. WHR is not optimal for diagnosis and evaluation of obesity.

Purpose: The aim of this study was to estimate the effect of Korean medicine treatment on overactive bladder. Methods: 64 patients of overactive bladder received Korean medicine treatment for at least 30days. We studied retrospectively symptom disappearance rate, the relationship between the improvement rate and age, scale of symptoms, BMI(Body Mass Index), WHR(Waist Hip Ratio). Results: Symptoms of 27 patients were disappeared, and those of 28 patients were improved. But 9 patients didn't show the improvement of their urination problems. The symptom disappearance rate was 43.08%. The improvement rate was 85.15%. The mean${\pm}$standard deviation of daily frequency was reduced from 10.05128 to 7.44872 after treatment(p<0.0001) The symptom disappearance rate was reverse-related with the OABSS score, KHQ and WHR. The improvement rate of married patients was higher than unmarried patients. And especially that was co-related with the frequency of acupuncture and moxibustion treatment. Conclusion: The results of this study suggested that Korean medicine treatments, such as acupuncture, moxibustion and herbal prescriptions have positive efficacy on overactive bladder patients in ordinary clinical practice.

Purposes: The purpose of this study was to evaluate the extent of performance on activities in critical pathway (CP) according to eight domains and six admission days on nursing records of patients who received total hip replacement surgery. Methods: We reviewed 90 nursing records of patients who received total hip replacement surgery from June, 2004 to July, 2005 at C University Hospital. Data were collected using Hong's CP (2002) and were analyzed using ANOVA. Results: The domain of diet was valued the highest in CP performance scoring, followed by the domains of assessment, activities, and test. There were differences in the performance scores according to the period of admission in all of the domains. Among 132 activities in the CP, 18 activities were completely performed, of which most included activities belonging to the domain of assessment on the admission day. Twelve activities were never performed, of which most included activities belonging to the domain of treatment on the day of operation and the first day after operation. Conclusions: Therefore, further studies on the development of a new system to increase CP utilization and on updating the contents of CP from the best practice based on evidence is recommended.

The present study was performed to analyze the gene expressions of pituitary adenylate cyclase-activating polypeptide(PACAP) and its receptor in the rat uterus, a candidate for novel extrahypothalamic source and target. The PACAP cDNA fragments corresponding to the common exon region which is found in both the rat hypothalamus and testis were produced from all tissue samples including the rat uterus by reverse transcriptionpolymerase chain reaction (RT-PCR). No PCR product was amplified from the rat hypothalamic, pituitary, ovarian and uterine samples when the 5' primer corresponding to the testis-specific exon 1 region was used, while the predicted size of product was detected from the testis sample. RT-PCR using the uterine RNA and specific primers for the PACAP receptor yielded products with predicted sizes. Transcripts for the rat uterine PACAP receptor were identified as type I isoforms with hip-hop and hip- or hop-type inserts. After pregnant mare's serum gonadotropin (15 IU) treatment of immature rats (day 25), the level of PACAP mRNA was increased in 24 h and 48 h group, and was declined to the lowest in 72 h group. The present study shows the presence of transcripts for PACAP and its receptor isoform in the rat uterus. These finding ssuggest that the uterine PACAP ight act as a novel autocrine and/or paracrine factor via its specific receptors on the reglulation of rat uterine function and physiology during the reproductive cycle.
