Multidisciplinary design optimization methodologies play an essential role in modern engineering design which involves many inter-related disciplines. These methodologies usually require very long computing time and design tasks are hard to finish within a specified design cycle time. Parallel processing can be effectively utilized to reduce the computing time. The research on the parallel computing performance of MDO methodologies has been just begun and developing. This study investigates performances of MDF, IDF, SAND and CO among MDO methodologies in view of parallel computing. Finally, the best out of four methodologies is suggested for parallel processing purpose.

The Scandinavian cluster of welfare societies has for many years been considered a realisation of Richard Titmuss' institutional redistributive model of social policy. Recent reforms have, however challenged this assumption. The paper sets out to evaluate whether recent major changes in welfare provision are merely modifying the model or whether the Scandianian states are converging towards some kind of European social model. It is concluded that besides very many first order changes, such as reducing benefits, an number of second and third order changes have occurred; i.e. the institutional setting and the objective of the welfare states have changed during the 1990s. The Scandinavian welfare states are still distinct, but less so than a decade or two ago. The new elements are features usually associated with welfare models at play within the European Union. It is, hence, concluded that welfare in Scandinavia is undergoing a process of Europeanisation.

The stress collapse in the formation of shear bands in elasto-thermo-viscoplatic materials is systematically studied within the framework of one-dimensional formulation via analytical and numerical methods. The elastic energy released in a domain is found to play an important role in the collapse behavior of shear localization. A non-dimensional parameter named the stability indicator is introduced to characterize the collapse behavior, with approximate forms of the incremental governing equations. The stability indicator offers useful information regarding the degree of severity of an abrupt change of deformations during the stress collapse. Numerical experiments are carried out to verify the stability indicator by varying material properties.

Hemopoiesis and morphogenesis of the human fetal liver through from 10 to 32 weeks of gestation were investigated by light and electron microscopy. The results obtained were as follows. Hemopoiesis of fetal liver tissue was found from 10 to 32 weeks of gestation, but the hemopoiesis was decreased at 32 weeks of gestation. At the 32 weeks of gestation, matured erythrocytes were observed in the sinusoid, and formation of liver cell cord and portal triad were established. Differentiation of hepatic cell was characterized by the increase of amount of cell organelles within cytoplasm, decrease of hemopoietic cell, morphological change of nuclear envelope from folding form to round form during the developmental period. These results suggest that human fetal liver plays a hematopoietic function until bone marrow and spleen play their function, but morphology of liver at 32 weeks of gestation was differed with structure observed in liver of adult.

Clinical neuropsychology which belongs to the necuroscience field is concerned with relationship between human behaviors and the brain structure. Clinical neuropsychology has grown to be a specialized separate field within psychology over the last twenty years. Clinical neuropsychology offers an objective methodology to consider the mind-body interaction and evaluate the behavioral consequences and functional deficits associated with brain lesions. Clinical neuropsychological assessment is composed of cognitive, perceptual, motor and emotional function through various neuropsychological examinations such as Halsted-Reitan and Luria-Nebraska batteries, and computerized neuropsychological test such as PCIS Vienna Test System and Stim. The goals of neuropsychological evaluation are to identify of neuropsychological dysfuncitions, to develop execute and monitor treatment plans, and to make rehabilitation programs. Recently, the neuropsychiatric patients are increasing in number and 15-20% of acute psychiatric patients suffer from organic mental problems. Moreover, clinical neuropsychology has an increasingly important role in both neurobehavioral foundation and clinical application. So, psychiatrists must play a major role in the development of clinical neuropsychology in psychiatry.

This paper describes the design and development of drills with deburring inserts. The drills can be used to drill holes and deburr the edges of the drilled holes simultaneously. The drills incorporate deburring inserts within the shank. The insert consists of a fixing base, a cantilever spring and a cutting tip. The stiffness of the cantilever spring and the details of the cutting tip play a central role for the successful deburring performance. The deburring performance is also governed by the conditions of the drilling burr best described by the burr control chart suggested by Dornfeld. With careful burr control, successful deburring is obtained by the drills with deburring inserts.

The production results of the oriental functional beverage, which is aimed at reducing the alcohol concentration in blood, are as follows. Different kinds of herb medicine ingredients were combined to achieve the balance between Yin And Yang. They were grouped according to their respective characteristics and extracted by heat, Then they were combined and produced following the most effective mixture ratio. The drink produced by this way consisted mainly of water, Sugar, mineral, protein and fiber were partially contained. Among the minerals, the proportion of calcium, potassium, magnesium was high and iron was also contained. This drink turned out to be effective in reducing the alcohol concentration in blood within a very short time when it was taken once after drinking and taken aging 30 minutes later, which would double the dosage. This result shows that development of such a functional beverage using the herbal medicine, At the same time it will play an important part in reducing the alcohol concentrate in blood after drinking liquors.

Though children are imperfect and immature in themselves, they have their own merits and characteristics, so that they should not be appreciated by the adult's own viewpoints. The needs of a child are obviously different from those of an adolescent or an adult. Therfore we should understand their mentality and psychology in order to give desirable outdoor space to them. In this study, children's view of outdoor environment was studied by analyzing the painting of object elementary school students of one and the other urbanizations and schooling years and different schooling years also. The data were drawn from 182 children of two different urbanization levels. The urbanization level was standardized with urban area(Taegu), and rural area(Jukjang - myon). According to the research, more area of garden was exprssed In paintings of urban children. House was expressed vy far more frequently in paintings of rural childrin than in those of urban dwellers. The children of urban expressed recreation facilities more frequently within their garden. It reflected the limitation of play space for them, As a result, the preference fur outdoor 7pare of children should by considered in Planning space for them.

A well-designed computer network technology produces benefits on several fields within the organization, between the organizations(suborganizations) or among different organizations(suborganizations). Network technology streamlines business processes, decision process. Graphs are useful data structures capable of efficiently representing a variety of networks in the various fields. Metagraph is a like graph theoretic construct introduced recently by Basu and Blanning in which there is set to set mapping in place of node to node as in a conventional graph structure. Metagraph is thus a new type of data structure occupying its popularity among the computer scientists very fast. Every graph is special case of Metagraph. In this paper the authors introduce the notion of Meta-Networking as a new network technological representation, which is having all the capabilities of crisp network as well as few additional capabilities. It is expected that the notion of meta-networking will have huge applications in due course. This paper will play the role of introducing this new concept to the network technologists and scientists.

Numerous evidence have been reported that fine particulate matters can play an important role in threatening human health. Recently concerns on fine particle pollution from various engines may require re-examination of particulate emission standards. The particles emitted by most diesel engines are mainly divided into their size ranges such as Dp< 50 nm and 50 nm< Dp< 1,000 nm. In this work, the number concentration and the size distribution of fine particles emitted from an exhaust manifold of a railroad diesel engine were measured under load test conditions using a scanning mobility particle sizer (SMPS). The fine particles observed were within the range of 7 to 304 nm under different load conditions with two different dilution ratios. The fine particles exhibited unique patterns showing bimodal shapes in size distribution.
