Myasthenia gravis is a disorder of neuromuscular transmission characterized by weakness and fatigue of voluntary muscles. It is now reasonably established to be due to an autoimmune attack directed against the postsynaptic nicotinic acetylcholine receptors of voluntary muscles. Thymectomy has become increasingly important in the treatment of this disease after the successful case of Blalock in 1939. From January 1984 to December 1988, we performed total thymectomy in 25 cases of myasthenia gravis except one, and get the results as follows. l. Among 25 cases, male to female was 10:15 and the age was ranged from 16 years to 65 years. 2. Thymectomy was done in 24 cases and 1 case of malignant thymoma was not resectable. 3. There were 2 deaths after thymectomy due to myasthenic crisis. 4. There were 19 cases [76 %] of improvement after thymectomy as follows; complete remission was 6 cases [24 %], marked improvement was 9 cases [36 %] and subjective improvement was 4 cases [16 %]. 5. The effect of age, and duration of disease on operative result was not statistically significant, but that of thymic pathology was significant.

The ceramic has various high mechanical properties such as heat, abrasion, corrosion resistance and high temperature strength compared with metal. It also has low speciffic weight, low thermal expansibillity, low thermal conductivity. However, it could not be used as structural material since it is brittle and difficult for the machining. Therefore, there have been many researches to attempt to join ceramic with metal which is full of ductillity in order to compensate the weakness of ceramic.The problem is that residual stress develops around the joint area while the ceramic/metal joint material is cooled from high joining temperature to room temperature due to remarkable difference of thermal expansion coefficients between ceramic and metal. Especially, the residual stress at both edges of the specimen reduces the strngth of joint to a large amount by forming a singular stress field. In this study, two dimensional finite element method is attempted for the thermal elastic analysis. The joint residual stress of ceramic/metal developed in the cooling process is investigated and the change of joint residual stress resulted from the repetitive heat cycle is also examined. In addition, it is attempted to clarify the joint stress distribution of the case of tensile load and of the case of superposition of residual stress and actual loading stress.

Purpose : This study was to evaluate the effectiveness of exercise therapies for breast cancer patients through review analysis of the rehabilitation they had usually received to increase the quality of their lives. Exercise therapy for breast cancer patients has proven to be highly effective, so it is strongly recommended. Method : Focusing on breast cancer-related journal articles published since 1990, an analysis using the Spolit and Medline search engines was undertaken of breast krebs, tumors, cancer, sportaktivitaet, and exercise in patients with breast cancer. Exercise for breast cancer patients has been considered to have positive effects on fatigue, muscle weakness, and the range of motion of upper extremities, as well as on depression. Breast cancer patients have to be divided according to their identifying clinical characteristics, and then have to be prescribed a suitable exercise program. In accordance with previous articles, a varied exercise program was organized in terms of frequency, duration, and intensity. The frequency was more than three times per week. Its duration was about 30 minutes per session. Result : The intensity of exercise was moderate. The types of exercises included recommended strengthening exercises, as well as various aerobic exercises. Based on previous data, a new exercise method for breast cancer patients was introduced in this study. Conclusion : Above all, exercise programs should be planned according to the different characteristics of breast cancer patients, in order to reduce physical impairments and psychological problems.

Adrenal insufficiency is caused by adrenal failure or impairment of the hypothalamic-pituitary-adrenal axis. The main symptoms of adrenal insufficiency are chronic fatigue, nausea, vomiting, anorexia, and weight loss. We report a case of adrenal insufficiency in a 38-year-old female. The patient complained of headache, dizziness, anorexia, and general weakness. We treated her with Iggisaengjin-tang and acupuncture. After treatment, the patient's symptoms were improved and serum cortisol levels rose to a normal range without the aid of steroid supplementation therapy. This case suggests that Korean medicine can be effective in the treatment of adrenal insufficiency, but more clinical reports are needed.

Gitelman syndrome is a condition caused by a mutation of the thiazide sensitive Na-Cl cotransporter gene on the distal convoluted tubule. It results in a variety of clinical features, including hypokalemia, hypomagnesemia, hypocalciuria, and metabolic alkalosis. It is often diagnosed in asymptomatic adults presented with unexplained hypokalemia; however, it is sometimes associated with muscular cramps, numbness, fatigue, weakness, or paralysis. We experienced a case of rheumatoid arthritis accompanied by Gitelman syndrome, presented with hand tremor. We diagnosed her using renal clearance study and genetic analysis. Here, we report our experiences regarding this case along with a literature review.

For the vibration reliability tests, the jigs for mounting the test specimen on a vibration reliability tester are required. The dynamic stabilities of the jigs should be verified before the tests for obtaining the accurate reliability of the test specimen. This paper proposes an analytical technology for ensuring the dynamic structural stability for the test setup including the jig. The technology includes the mode analyses for checking resonance, the harmonic analyses for evaluating the dynamic structural stability of test setup including the jig, and the fatigue analyses for obtaining the durable reliability time with calculating the life cycles at the area of weakness. The cause investigation of the damaged jig during vibration reliability test of a rubber hose and the design of new revised jig are performed by using the technology. The vibration reliability test for the rubber hose with the new revised jig by analysis results is successfully conducted without any problem. Therefore the jig's design technology proposed in this paper may be useful for other items as well.

The chief complaint was mainly categorized by oral examination on patients and their care-givers. Result 1. The numbers of children who involved in this study is total 1245: Male children are 668 and female children are 577 children. The sex rate between male and female is 1.15 to 1. 2. Most of the above patients came to the hospital at first time from diseases such as musculoskelectal disease, weakness, asthma, cough, anorexia, common cold, rhiorrhea, sweating, dyspepsia, dematitis, night terror, obesity, stomach, short stature, Besides, they also came to the hospital at first time from various diseases such as epistasxis, pyrexia. Bell's palsy, nocturia, contipation, cerebral palsy, disorder, CVA. diarrhea. stress disease, Allergic disease, Tic disorder. Visual disorder, Kawasaki disease, Pierre Robin's syndrom, hematuria, edema and so on. 3. Looking at the frequent diseases, Respiratory dis. children including asthma, cough, rhiorrhea, sweating, common cold, pyrexia covers 36%, in 399 numbers. digestive dis. children including anorexia, dyspepsia, stomach, diarrhea, constipation, indigestion covers 19%, in 211 numbers. cadiovasculary disease children including arrthymia, terror in frequency, night crying, sediation, Tic disorder covers 8%, in 85 numbers. Hepatobiliary disease children including short stature, dizziness, visual difficulty, sprain, disorder of nail covers 21%, in 238 numbers. renal disease. children including nocturia, hematuria, hemation, disorder of hair, menorrhea, cerebral palsy, edema in 44 numbers. Fatigue children covers 13%. in 143 numbers. 4. In case of respatory disease children. total number is 399 children. dematitis children are 108 numbers and asthma children are 96 numbers. These show that children seem to the best have dematitis and asththma. The age from 0 to 6 is 290 numbers, covering 73 percentage. The others are covering 27 percentage. These data demonstrate that the age from 0 to 6 age could easily get these kinds - of diseases. The 29 percent of children had these kinds of diseases in spring. The 28 percent of children had these kinds of diseases in autumn. These show that children seem to frequently have these kinds of diseases in both spring and autumn season.(inter-season) 5. In case of digestive disease, anorexia covers 39%, in 83 numbers, dyspepsia covers 28%, in 59 numbers, anorexia and dyspepsia were the lagest group in digestive disease and the age from 0 to 6 covers 59%, in 125 numbers and the other age covers 39%. According to these data, infant seems to be vulnerable to these kinds of diseases. The 24 percent of children had these kinds of diseases in spring and summer. The 33 percent of children had these kinds of diseases in winter, which means that children mostly had winter. but decreased significant in autumn. 6. In case of cadiovasculary diseases, it can be divided into two categories: night covers 73% and nervous characteristics covers 27%. The age from 0 to 6 occupies 75%, and the other age occupies 25%. These data also show that infants can easily infected with these kinds of diseases. Analyzing by the season, summer could be the most frequent season that children have these kinds of diseases. but decreased in autumn. 7. In case of hepatobiliary children, sprains covers 166 numbers, fatigue covers 32 numbers, epistasxia covers 24 members, the reasion which sprain occupyied most of % were sprain covered ages. The age from 0 to 14 covers 59% and from 15 to 18 covers 41%. In the conclusion the adolescent seems to be vulnerable to sprains. In spring 29%, insummer 31%, in autumn 23%, and in winter 28% of children got these kinds of diseases, which show that children seems to have this kinds of disease in summer season. and decreased in autumn. 8. In case of renal disease. nocturia and hematuria covers 52%(occupied overhalf). The age from 0 to 6 covers 52%(occupied overhalf). Analyzing by season, in spring increased in summer(59%), decreased in autumn(45%) Conclusion 1. The chief complant in pediatric diseases that needed an oriental medical tretment was mainly the disease that tends to take iong time and the weakness. and appeared frequency in respiratory disease : 2. The oriential medical tretment was still preferred as a way to improve the weakness by patients, rather than a way to overcome their disease. In paticular, the study shows that the oriental medical tretment should be emphasized in terms of preventing the disease 3, The new disease, which were developed with the change of human life and envir oment(just like seual disorder, short stature, obesity, dynamic disorder, examinee disease), should be in vestigated as a new field of oriental medical tretment.

This study of purpose was to define the relationship between the stress and climacteric symptoms of middle-aged women in order to provide basic data for the development of women's health care program as nursing intervention. The research tools used were a Soon-Young Park's stress questionnaire (4 points scale) and a self diagnostic MENSI scale (3 points scale) developed by a research team of Ill-Yang Pharmacy Co. This research was conducted in Korea in Muan-Gun. Chonnam province, from 22th November to 20th December 1999. The research used a survey design. Seven hundred eleven healthy middle-aged women, aged 40 to 64, and were a convenience sample by stratified ratio using the matching fixed residential and aging blocks. The data were analyzed by GLM. Pearson correlation coefficient and Scheffe test using SAS/ PC+. The results were summarized as follows : 1. The percentage of psychological stress with the following items was: fatigue and enervation, 70.0%; nervous, 61.8%; weakness, 58.5%; The percentage of physical stress with the following items were ; fatigue of eye. 82.3%; backache, 78.0%; headache, 73.8%. 2. The level of psychological stress was 40% of below average level (0-5 points), 31.7 of average level (6-12points), 20.8% of precaution level (13-19 points), and 7.5% of warning level (over 20points). The level of physical stress were 20.1% of below average level (0-5 points), 34.8 of average level (6-12 points), 29.4 of precaution level (13-19 points), and 15.7% of warning level (over 20 points). There were higher physical stress level than psychological stress level of the subjects. 3. The percentage of climacteric symptoms with the following items were : numbness, 75.3%; forgetfulness, 71.0%; pain of joints, 71.0%. The level of climacteric symptoms were 61.8% of mild level 1(10-15 points), 33.0% of moderate level (16-30 points), 5.2% of severe level (over 31 points). 4. There were high positive correlations significantly between the climacteric symptoms and the psychological stress (r=.564. P<0.000), and between the climacteric symptoms and the physical stress of the subjects(r=.678, P<0.000). 5. There were significant differences in the climacteric symptoms of the subjects among below average level, average level, precaution level, and warning level of the psychological stress (F=74.108. P<0.000. Scheffe test). 6. There were significant differences in the climacteric symptoms of the subjects among below average level, average level and precaution level, and warning level of the physical stress ((F=128.181, P<0.000, Scheffe test). In summary, climacteric symptoms complained by middle-aged women are high positive correlated to the level of the stress. Also climacteric symptoms were affected by stress.
