Purpose : The purpose of the study was to examine if a respiratory muscle strengthening training in patients with stroke can improve their pulmonary function. Methods : Volunteers were included for the study if a patient diagnosed stroke more than 6 months and had 24 points or higher in MMSE-K scores. Twenty-eight subjects participated in this study and were randomly divided into two groups; a breathing exercise group(n=14) and a control group(n=14). The intervention for all subjects was conducted for 20minutes, three times a week for 4 weeks. Subjects for the breathing exercise group had the respiratory muscle strengthening training using spiro-tigers, where-as subjects in the control group got their usual treatment ie a postural training. The six-minute walking test(6MWT) and the pulmonary function tests(FVC, $FEV_1$, $FEV_1$/FVC, VC, Vt, IRV and ERV) were employed to assess treatment effects at baseline and after their intervention. Results : Twenty-four subjects finished their 4-week treatment programs. The general characteristics between groups were found to be similar (p>0.05). The pulmonary function between groups were also observed no difference across groups at the baseline measurement (p>0.05). In the post treatment group comparison, subjects in the breathing exercise group showed an increase in lung function with VC ($2.73{\pm}0.80{\ell}$) and Vt ($0.87{\pm}0.38{\ell}$) than those in the control group ($1.91{\pm}0.80{\ell}$ and $0.48{\pm}0.22{\ell}$ respectively) (p<0.05). However, there was no difference found in 6MWT, FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV across groups (p>0.05). Conclusion : A significant increase in VC and Vt was found in subjects with stroke, who had four-week training on respiratory muscle strengthening. However, respiratory muscle strengthening showed no effect on walking speed and FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV in patients with stroke.

3파 상호작용은 천수파 또는 유한 수심 풍파의 경우에만 중요한 것으로 알려져 왔다. 파랑 성분간의 에너지 전달에 의한 풍파의 성장 관점에서 볼 때 심해에서 3파 상호작용은 4파 상호작용에 비해 별로 중요하지 않다. 그러나, 심해에서도, 특히 풍파 성장의 초기 단계에서는, 3파 상호작용이 중요할 수 있는데, 이는 3파 상호작용이 쇄파에 결정적인 영향을 미치는 파형경사, 수면 위에서의 공기 흐름의 항력, 선박의 항해 등과 밀접한 관계를 가지고 있기 때문이다. 본 연구에서는 일련의 실험실 실험 결과를 제시하고, 이에 대한 bispectrum 분석을 통하여 심해 풍파의 3파 상호작용을 고찰한다. 스펙트럼 첨두 주파수에서의 bicoherence와 파형경사가 거의 정비례하는 것으로 나타나는데, 이는 파봉이 뽀족하고 파곡이 밋밋한, 경사가 큰 파가 3파 상호작용의 결과임을 나타낸다. Bicoherence 및 파형경사 모두가 파랑 성장의 초기 단계에서는 파령에 따라 증가하다가 파랑이 발달함에 따라 다시 작아진다. 파랑 성장의 초기 단계에서 3파 상호작용에 의하여 발달된 스펙트럽 2차 첨두의 에너지가 그 이후에는 4파 상호작용에 의해 주변의 주파수들로 재분배되는 것으로 추측된다.

Garlic occupies a special position among the many foods of vegetable origin because it is the sole food for Koreans during the their lives. And vitamin A has been ingested by forms of food or additives. Cadmium has been described as one of the most dangerous trace elements in the food and environment of man and livestocks. Since the de novo synthesis of stress proteins can be detected early after exposure to some agents, analysis of cadmium-induced changes in gene expression , ie. alterations in patterns of protein synthesis, may be useful to develop as biomarkers of exposure and damage for food hygiene. He acute and chronic combine effects of cadmium (Cd, CdCl2 20mg/kg), garlic oil(Dds: diallyl disulfide 50mg/kg, 3 times a week) and vitamin A(Ra: retinol acetate 50,000 IU/kg, 3 times a week) on Wistar male rats were evaluated concerning cadmium contents, tissues enzyme activity, HSP expression histopathological and electron microscopical examinations. The results of the study are as follows ; 1. Less cadmium was absorbed through the digestive tracts, but the ratio of contents in tissue were not changed by the simultaneous adminstration of diallyl disufide or retinol acetate. 2. ALT(alanine aminotransferase) , AST(aspartate aminotransferase), glucose, BUN (blood urea nitrogen), creatinine, the key indices of the clinical changes in hepatic and renal function were significantly hanged by the cadmium treatment after 1 week in liver, after 4 weeks in kidney. 3. Histopathological changes in cadmium treated rats were appeared at 8 weeks age treatment in kidneys. Homogenous eosinophilic material was accumulated in cortical and collecting tubular lumens at 16 weeks. Degenerated or necrotized tubular cells were observed in cortex and medulla. Degenerated seminiferous tubules and homogeneous eosinophilic material was seen in interstitial tissue of rat treated with cadmium for 16 weeks. Calcium deposits were seen in degenerated seminiferous tubules and the tubules showed severe calcification of rat treated with cadmium for 16 weeks. Electron microscope changes in kidney were observed in rats treated with CdCl2 20 mg/kg. Proximal convoluted tubule cells showed selling of cytoplasm and narrow lumen. Capillary endothelial cells showed cytoplasmic vacuoles and swelling. Degenerated epithelial cells were accumulated in tubular lumen of kidney. 4. Enhanced synthesis of 70 KDa relateve molecular mass proteins were detected in 2 hours after cadmium, exposure, with maximum activity occurring at 8~48 hours. Induction of HSP 70 was evident at proximal tubules and glomeruli in kidney. Testicular cells produced enough HSP to be detected normally. From the above results, it could be concluded that HSP70 induction by the cadmium treatment was a rapid reaction to indicated the exposure of xenobiotics, and retinol acetate reduced the cadmium induced nephrotoxicity.

Background: Primary malignant lymphoma of the parotid gland is a rare disease and defined as any malignant lymphoma that first manifests in the parotid gland, regardless of the subsequent stage of the diseases, whether it arises in the parenchyma or intraglandular lymph nodes. This study was performed to review the clinicopathological characteristics of primary parotid lymphoma and identify its optimal treatment modality. Materials and Methods: Six cases with parotid mass as first presentation of malignant lymphoma between 1988 and 2000, were studied on the basis of clinical features, diagnostic tools, treatment modality, treatment outcomes, and clinical stage by Ann Arbor Criteria. All were microscopically reevaluated and classified by NCI working formulation. Results: All patients were males and mean age was 36.7 years (2-66 years). Rapid growing non-tender mass was presented in all the cases and cervical lymphnodes were palpated in 4 cases. However, there was not any evidence of concurrent autoimmune disease such as Sjogren's syndrom or Rheumatoid arthritis. One case was confirmed by surgical specimen after superficial parotidectomy, 2 by excisional biopsy, and 3 by incisional biopsy. The stage of disease by NCI working formulation was IE in 1 patient, IIE in 4 and IV in 1. All were classified into non-Hodgkin' lymphoma, of which there were 5 cases of B-cell type and 1 case of T-cell type. There were 3 diffuse large cell lymphomas, 1 Burkitt lymphoma, 1 MALT lymphoma and 1 T-lymphoblastic lymphoma. Three cases were treated by chemotherapy only, 2 by radiotherapy only and 1 by chemo-radiotherapy. One case with Burkitt lymphoma was died from the disease and one case was lost to follow-up. The others are alive with no evidence of recurrence. Conclusions: Although primary parotid lymphoma is rare and difficult to diagnose preoperatively, most were detected in early stage and showed a relatively good response to the chemotherapy or radiotherapy like other types of extranodal malignant lymphoma.

This study is fulfilled from September 1st to December 31st in 1999 and the object of investigation are all 289 students belong to 5 universities managing amateur Ssirum team in Kyungnam, Kyungpook. Pusan and Seoul(158 people) and 6 high schools(131 people). And these results were derived from percentage and cross analysis of Person Chi-square test ann interview and 47 questioned paper based on this purpose of study. 1. There were no significant differences between high school students and university students in the comprehension of physical therapy and injury occurrence by technique. 2. According to the relation between satisfaction of life as a player and injured part, the injury of soft tissue ranked high among satisfied and unsatisfied people. and the satisfaction or unsatisfaction of practicing place also derived same result. 3. $46.8\%$ of Ssirum players got the injury of soft tissue during practice. the articular injury and bone injury in regular sequence. But there were no relations between the time of injury and the sort of injury. 4. There were no statistical differences ortho sort of injury by technique.(p=0.399). 5. According to the part of injury by using techniques, the injury of soft tissue ranked high$(50.0\%)$, articular injury ranked high$(42.6\%)$ in the leg technique, bone injury ranked high in the leg technique, and nerve injury ranked high in hand technique. 6. The injury of soft tissue ranked high during the practice$(46.8\%)$, practice on the purpose of a match$(50.0\%)$ and match$(41.7\%)$ but there were no relations between the time of injury and son of injury. 7. The part of injury by technique ranked high in the soft tissue$(50.0\%)$, articular injury by leg technique$(42.6\%)$, bone injury in leg and waist technique and nerve injury in hand technique high. 8. The time of injury ranked high during the practice$(65.7\%)$, and $66.1\%$ of injury occurred in the afternoon. 9. During the practice, the cold weather ie related on the rate of injury because $67\%$ of injury occurred in winter, but there are no statistical significance. 10. There were no relations between the satisfaction of place far practice and time of injury. 11. The particular part of injury occurred very much during the match between defense and offense. 12. In the relation between the degree of understanding of physical therapy and the experience of physical therapy, the people who know physical therapy had much experiences of physical therapy(p=.000) And independent of the physical therapy experiences, the effectiveness of physical therapy therapy to players was $48.8\%$, no idea was 42.65 and no effectiveness was $8.7\%$(p=.000). 13. $59.6\%$ of the people admitting the physical therapy effectiveness answered they would follow the order of the doctor and $56.6\%$ of the people not admitting the physical therapy effectiveness answered no.
