Slab design procedures are presented in detail in the Structural Standard Criteria. These are the Direct Design Method, the Equivalent Frame Design Method, and the Factored Method, is allowed under an appendix II in the Structural Standard Criteria. Slabs are frequently built with beams spanning from column to column around the perimeter of the building. These beams act to stiffen the edge of the slab and help to reduce the deflection of exterior panels of the slab. The distribution of the moment in slabs differ according to the flexural stiffness ratio of the beam to the flexural stiffness of a width of slab bounded laterally by the centerlines of the adjacent panels on each side of the beam Later a study of the relation between the distribution of the moment and the aspecft ratio of the slab, ι_(2)/ι_(1), and the relative stiffness, α, the slab with spans of 7.5m x 5.5m has been analyzed by each slabs design method A comparison of the slab moment from the Finite Element Method analysis, the Direct Design Method, the Equivalent Frame Method, and the Factored Method show for here are 1. If the relative stiffness of the beam by the aspect ratio of the slab will be more than 1, distribution of moment assigned to the column strip is strongly affected by the aspect ratio of the slab than the relative stiffness of the beam in the Direct Design Method and the Equivalent Frame Method. Since the aspect ratio of the squar slabs like model 1-1,1-2,1-3, equal to 1, the distribution in slab isn't sensitively affected by the relative stiffness of the beam 2. For a long span/short span(λ) equal to 1.36:1, Model 2-1,2-2,2-3 which computed by the Direct Design Method and the Equivalent Frame Method shows similar stress distribution or lager one compare with the Finite Element Analysis. On the other hand, the Factored Method underestimates the stress in long span direction and overestimates the moment in short direction. As the beam size become big, the variation of stress distribution decrease, only the positive moment which computed by the Direct Design Method and the Equivalent Frame Method in the middle strip in short directon underestimates compare with the Finite Element Method Analysis. As the beam size become big, the variation of stress distribution increase.

This paper compared and analyzed DAS, NAS, SAN as large scale storage systems, in terms of the characteristics, price, interoperability, performance, availability, usability and economic features. Also, iSCSI was introduced as a new network storage system. DAS is considered as an old and non-promising systems as the next generation network storage system for slow data transfer speed, and the lack of interoperability. It is not easy to evaluate which is a better system between NAS and SAN for large scale network storage systems. NAS has the advantage on the interoperability and the usability, whereas SAN has the advantage on the scalability. In the future, however, iSCSI system which combines the merits of SAN and NAS, is expected to dominate the large scale network storage system market.

Diabetes Mellitus which can be caused by various factors is known to induce changes in the pancreatic islets. With Wistar albino rats, this experiment was designed to observe quantitatively the islet changes due to increasing age and sex difference by using the method of Cardell on sections of tissues. The experminental animals were bred with regular diet, and were sacrificed at the age of ten, twenty, thirty, forty, and fifty weeks, repective.y. The pancreatic tissue were fixed in Bouin's solution, and their sections were stained with hematoxylin and eosin. the long and short diameters of pancreatic islet were measured with ocular micrometer under the microscope and its surface area per 100㎟ of the pancreas was calculated. REsults obtained are as follows: 1. The pancreatic islet of the young animals show normal aooearance but those of the old are enlarged. 2. The increase in the body weight is marked more in the male than in the female. 3. The surface area of the islets per 100㎟ of the pancreas shows significant increase in the male, but its increase in the female is not significant. 4. Even though the size of pancreatic islets in the rats of forty-week-old group is small, the fraction of surface area of the islets shows the increase. It seems to mean the hyperplasia of the islets. 5. From the above results the sex and increase in the age can be the causes of diabetes mellitus, and the changes of its pancreatic islets are hyperplasia as well we hypertrophy.

This paper focuses on integrating NAS and SAN and making large scale storage systems. Traditionally, NAS has been widely used as a large scale storage system for its advantage on the interoperability and the usability. On the other hand, SAN has the advantage on the scalability. As the demand for large scale storage systems becomes bigger, it is asked for combining NAS and SAN as an integrated system. Since it is not easy to evaluate which is a better system between NAS and SAN for a large scale network storage system, the integration effort has been devoted to exploiting the advantages of NAS and SAN. Three methods are studied and described in this paper, the Meta data server method, the Server software method and the combining method. Among them, the combining method becomes the de facto standard in the field for integrating NAS and SAN as a unified large scale network storage system.

The ultrastructural development of fetal liver cells according to the activity of hepatic erythropoiesis was studied with 15 human fetal livers from 7 to 34 weeks of gestation. 1) The 1st state(7-8 weeks of gestation) : The nucleus of hepatocyte was oval with granular euchromatin evenly dispersed throughout the interior and prominent nucleoli. The hepatocytes often exhibited many mitochondria and short dilated rERs but no sERs and glycogen deposit. Two types of reticulum cells with intracellular organells developed with close relation with erythropoietic cells. The nucleus of the 1st type was similar with that of hepatocyte and the cytoplasm was full of well-developed multiayered rERs and numerous mitochondria. The nucleus of the 2nd type was irregular and has high electron-dense nucleoplasm. and the cytoplasm was packed with more developed multiayered rERs and oval mitochondria. 2) The 2nd state(9-22 weeks of gestation) : Most of hepatocytes differentiated well and exhibited numerous mitochondria and free ribosome, 5 to 6 layered rER, glycogen deposit, and there were sppearance of sER and hemosiderin in the cytoplasm. With age, the 2nd type reticulum cell became the majority and had more glycogen deposit and less rER. The space of Disse was well-developed but the sinusoidal wall still immature. 3) The 3rd state(23-34 weeks of gestation) : The majority of hepatocytes were mature cells. Reticulum cells, greatly decreasing with age, exhibited increasing lipid storage and decrease of mitochondria and rER. In summary, the maturation of hepatocyte and activity of reticulum cell may influence the hepatic erythropoiesis.

Recently, the South Korean government tries to construct in the central region of the country a city specially destined to shelter most of the complex of its governmental bodies. Having this in sight, this work tries to analyze cultural influences that such project can make in the national scope, because a city of such dimension is and functions as symbolic sign for diverse aspects of the political, economic, social and cultural life of its people. For that end, we choose the capital of Brazil, Brasilia as research object, because we believe that, being the capital constructed more recently of the world(1960), it will serve for our study to see various aspects that can be generated with the construction of that our city. Specially, we will concentrate our attention on the study of various aspects of ideology of the ruling class and bureaucratic authoritarianism of years 1950-60, that were impregnated widely in that project of national dimension. Also we try to understand how the new capital functioned for the project by which the Brazilian people wanted to find and consolidate its national identity and the Brazilian culture blossomed greatly. As it is known, with the construction of new symbolic sign, Brasilia, the national integration of the brazilian people sped up and in its base it made possible the splendid development of its popular and national culture. Although several critics were made against the construction of Brasilia in terms of failure in solving chronical problems as social desiguality, democratic distribuition of incomes, etc, we cannot deny that the construction of Brasilia, such as a symbolic sign,was crucial factor for the consolidation of national identity of its people and, consequently, for the national integration.

This study was aimed at preparing basic dada required for establishment of a cancer screening program by examining the status of cancer screenings performed by women in a city and the factors that had an influence on cervical and breast cancers screening behavior of women. In order to find out the status of cervical and breast cancers screening and the factors having an influence on cervical and breast cancers screening behavior, 1,113 women were selected as study area and subjects by a random cluster sampling method, and the subjects were answered by questionnaires. The major results were as follows. 1.In the cases of the breast and the cervical cancers, 16.7% and 55.7% of the subjects turned out to have had one or more screenings respectively in their life-time. Also the rate of screening group of cervical and breast cancers was 16.7%, the rate of screening group of only cervical cancer was 38.9%, and the rate of non-screening group was 44.4%. 2.As to the screening pattern of cervical and breast cancer, there were significantly for age, income, occupation, married status, spouse, the factors associated with health promotion (doctor visiting, exercising), married age, number of children, and breast feeding(p〈0.05). 3.The factors associated with screening behaviors for cervical and breast cancers were age, income, occupation, married status, doctor visiting, exercising, married age, number of children, and breast feeding(p〈0.05). Based on the above-mentioned results obtained by this study, it was anticipated that this study may be play a vital role as basic data for the development and execution of cervical and breast cancers screening program for women in a community. And the analysis, done on the basis of the status of the cancer screening, of the influence factors on cervical and breast cancers screening behavior showed that for the development of a cancer screening program, the factors like age, social-economic class, married status, health promotion behavior, and reproductive characteristics should be considered.
