Two-dimensional slow viscous flow due to the rotation of hinged plates with equal length and equal angle spaced is investigated on the basis of Stokes' approximation. An exact formal expression for the flow is obtained by use of Wiener-Hopf technique. From the formal expression obtained, the flows between two neighboring plates and near the leading edge of plates are discussed. The force and moment exerted on each plate are also calculated as functions of N, the number of hinged plates.

The purpose of this study is to suggest the alternative methods of the improvement of residential environment, focusing on the Incumbent Upgrading, through the participation of the interested parties in a site. One of the critical issues in the improvement of the residential area is re-dwelling of the tenant. However, there has not been considered it in the design process. At the results of those kinds of residential developments, there have resulted in side-effects, disharmonious of either urban landscape or urban grain, the lack of Infra-structure, and even effected on a negative influence in terms of social aspects such as free-rider, unequal distribution of development profit, and so on. Consequently, this study focused on the design solution for the improvement of a residential area considering the grain, the tenant, and defined the effectiveness of the alternatives by comparing it with existing design approaches in the aspects of physical factors.

Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

It is recent that the nation gets interested in the aged's participation in practical physical education and their life satisfaction. The fact that some factors influence the aged's life satisfaction has been proved by other scales. However, the relationship between the aged's participation in practical physical education as an activity for leisure and their life satisfaction has not been concretely researched yet. Under this circumstance, it requires the the efforts to research the social psychological process resided in the extent that the aged's participation in practical physical education make contribution to their life satisfaction, and in the relationship between the aged's participation in practical physical education and their life satisfaction. The purpose of this study is to specify from the viewpoint of the behavior theory the relationship between the aged's participation in practical physical education and their life satisfaction, and between the aged's participation in practical physical education and their satisfaction with leisure. First, it is found that among the aged's social and demographic characteristics, subjective factors like health, education, income, and age have influence on their life satisfaction. It shows that the aged's social and demographic characteristics, have influence on their life satisfaction, 24.7% of the total. Secondly, it is found that life satisfaction is higher in the group of the aged who participate in practical physical education than in the group of the aged who don't participate. The aged's participation in practical physical education increases their satisfaction with leisure which plays a role of a parameter for their life satisfaction. By doing so, it indirectly influences their life satisfaction, holding 9% of the total change in their life satisfaction. That is, it is a very influential factor on their life satisfaction. Based on the results, this study proposes that the aged's participation in practical physical education can heighten their satisfaction with leisure and further, improve their life satisfaction.

The purpose of this study was to assess daily living and health-related determining physical function, using a elderly group. Ninety five Korean elderly volunteered for this study. Each participants signed and informed consent and completed a written questionnaire requesting information about theft health, functional status, and physical activity level. The physical Function items represent body composition(waist girth), cardiovascular endurance(800m walking), flexibility(sit and reach), muscular strength/endurance(arm curls, 3G minutes sit and down of chair), balance(balancing on one leg with eyes closed), and agility(agility course). The results of physical characteristics and physical function tests are expressed as mean values standard deviations. Each physical function tasks representing activity of daily living had to demonstrate a significant correlation with age. In order to reduce the all items to a singe score, the correlation matrix for the items including age was subjected to principal component analysis. The main idea of this analysis is to reduce the dimensionality of a data set, which consists of a large number of interrelated variables, while retaining as much as possible the variation present in the data set, The first principal component was used as the best single descriptor of total daily living-related physical function tasks. The first principal component scores were computed for each subject. Because the scores generated by the principal component analysis were expressed in dimensionless units, it was considered desirable to convert these scores to units of ages, The total physical function score was considered useful in assessing functional fitness of daily living in the Korean elderly.

The experiment was carried out to establish of labor-saving control system on paddy field transplanted young rice seedling by machine. We examined the effect of control value between conventional control method that applied 6 times to paddy field during cultivation period and labor-saving control method that applied systematic pesticide one time to the seed, to the nursery box at transplanting day and twice to the middle stage of rice cultivation. The control value in labor-saving control method of Laodelphax striatellus, Nephotettix cincticeps and Lissorhoptrus oryzophilus were 93.4%, 92.7% and 86.1% compared with untreatment field, respectively and also the labor-saving method was more efficient than conventional control method at early stage of rice cultivation. The control value in labor-saving method of Nilaparvata lugens, Sogatella furcifera, Cnaphalocrocis medinalis were more than 84% and these showed almost same trend with conventional control method. The control value in labor-saving method of leaf blast and panicle blast were 91.7%, 93.8%, that showed similar result with conventional control method. The control value in the nursery box at transplanting day of sheath blight was 83.6%, these result were better than conventional control method that applied 2 times at middle stage of rice cultivation.

In Korea, the proportion of 65-year-old elderly population were gradually increased and over 7 percentage in 2000. To care elderly properly, various type of healthcare institutions is needed. There is general hospital and long-term care hospital among medical institution. In this study, difference of functional status and severity between elderly inpatients in general hospital and those in long-term care hospital was investigated. Comprehensive functional status of 577 patients that were hospitalized in 3 long-term care hospitals and 2 general hospitals was examined. On the contrary to our expectation, patients in long-term care hospital had lower activities of daily livings and more severe medical conditions than those in hospital. These results suggested that healthcare system and healthcare resource distribution for elderly patients are not worked efficiently.
