The aim of this study was to find out the differences of biomechanical factors from touching down the vaulting board to landing when techniques of 1/1Turn, stretched, and Tucked were performed on the old vaulting horse and on the new vaulting table. Three national representative men gymnasts were sampled for this study. Three dimension motion analyses by means of six Sony PD-150 video cameras with the velocity of 60 fps were used. As a result of analyzing the kinetic data from two kind of vaulting table, the following conclusions were made. 1. There was not significant differences of angular momentum between the old and the new vaulting table in all three techniques except the phase of stepping on the vaulting board and contacting the vaulting horse in the Tucked technique. IN the two phases above, the angular momentum in the new vaulting table was greater than that of the old vaulting horse. 2. There were few significant differences between the old and the new vaulting horses in the horizontal and vertical reaction force according to techniques when stepping was performed. However, it appeared tendency that the horizontal and vertical reaction force in the new vaulting table was a little greater than that of the old vaulting horse when the 1/1Turn, the Stretched and the Tucked were performed.

The performing time from taking off the vaulting horse to landing(phase 4) in the 1/1 Turn technique on the new vaulting table was significantly longer than that of the old vaulting horse, while the time from contacting to taking off the vaulting horse on the new vaulting table was shorter than that of the old vaulting horse in both and the Tucked techniques. 2. The vertical release COG velocity was faster on the new vaulting table compare to the old vaulting horse in the all kind technique. However the horizontal release COG velocity of the 1/1 Turn technique was faster a little in the old vaulting horse compare to the new vaulting table.

Hehage production, botanical composition and soil chemical characteristics were investigated Ween new pastures and old pastures during grazing seasons from May 1993 to October 1994, to find out the condition of pastures grazed by horses on Chdu. Dry matter yields between new pastures and old pastures were 8,757kglha and 7,486kglha respectively. Plant heights of new pastures were 17.4cm. compared with those of old pastures of 12.lcm. The botanical composition of new pastures was composed of grasses about 402, legumes 7~14%, others 18-30% and dead materials 18~ 25%. whiie there were grasses 12%, legumes 3~7%, others 65% and dead materials 15% in old pastures. The contents of crude protein, phosphoms and sodium were lower in old pastures(l3.30, 0.24 and 0.10% respectively) than those in new pastures(l5.47, 0.28 and 0.14% respectively). There was no difference in ADF, NDF, Ca, Mg and K content between the 2 kinds of pastures. The chemical characteristics of the 2 kinds of pastures was shown to be similar, except available phosphorus, comparing 8.18ppm in old pastures with 84.43ppm in new pastures. Although the herbage yield and the soil characteristics of old pastures were lower than those of new pastures, we suppose that the old pastures would be improved, if taken good care of by methods such as oversowing and sometimes applying fertilizer.

Domains are the building blocks of proteins. Exon shuffling is an important mechanism accounting for combination of a limited repertoire of protein domains in the evolution of multicellular species. A relative excess of domains encoded by symmetric exons in metazoan phyla has been presented as evidence of exon shuffling, and symmetric domains can be divided into old and new domains by determining the ages of the domains. In this report, we compare the spread, versatility, and subcellular localization of old and new domains by analyzing eight metazoan genomes and their respective annotated proteomes. We found that new domains have been expanding as multicellular organisms evolved, and this expansion was principally because of increases in class 1-1 domains amongst several classes of domain families. We also found that younger domains have been expanding in membranes and secreted proteins along with multi-cellular organism evolution. In contrast, old domains are located mainly in nuclear and cytoplasmic proteins. We conclude that the increasing mobility and versatility of new domains, in contrast to old domains, plays a significant role in metazoan evolution, facilitating the creation of secreted and transmembrane multidomain proteins unique to metazoa.

Regeneration of old buildings is one of the most imperative responses to the 21th century issue of sustainable urban architectural environment. In particular, creative circulation of generation which conversion means highlights the conversion as a new design method. In this study, by examining buildings built over the last decade, the mutual relationship between old elements of existing buildings and new elements of newly required functions was analyzed and types of relationships such as 'alien insertion', 'mediate intervention', 'endogenous expansional enveloping', 'contrastive confliction' and 'over-layering' were defined. In addition, design strategies including the paradoxical curio, fore-grounding and unification were derived from each relationship. Finally, according to the relation type and design strategy, this study suggests several features of conversion design; (1) maximization of symbolism using unfamiliarities - emphasizing futuristic or contextual symbol with intentional contrasts by preserving the work or using contemporary addition; (2) time confusion using neutral space - meeting the need by harmonizing and cooperating existing elements and new elements; (3) mutual emphasizing by individualization - revealing differences between old and new for an aesthetical tension; (4) synchronism by constructional combination - making the one unity of different layers; (5) expansion by enveloping - experience of visual reverse and creation of extra space by roofing above building groups. The reconversion should be continuously researched in the future since conversion is a sustainable design method for the future of architecture.

In the case of a rail road bridge extension work, especially single track to double track, the foundation of new substructure which supports the extended part of superstructure could be interfered by the exist foundation of an old bridge. When these two foundations are jointed to prevent such fatal effects of the structure as unequal subsidence of soil foundations, it is important to prove the structural behaviour of the joining surfaces between new foundation and old foundation. 3-Dimensional Finite Element Analysis Method have been studied for the solutions of the structural behaviour of the foundations. In this analysis, 'Contact Element' which allows the sliding of each adjoining member is used for the joint of the boundary surface of the old and new pier foundations. Furthermore, Material Nonlinear Behaviour Analysis also supports the accuracy of the result in this study because the foundations consist of concrete main bodies and reinforced steel bars. These detailed analyses secure the verification of the structural safety of the foundations in the extension work more firmly.

The baby boomers born between 1955 and 1974, recently called the new age, form a huge population group and show characteristics different from the previous traditional older generations. With the retirement of those who make up 33% of the nation's population in earnest, the emergence of a new generation of the elderly population and policy changes are required. The new middle age generation, also called the opal generation, want to spend their old age productively and autonomously, which has increased due to the increase in life expectancy, and have some economic ability, such as enjoying overseas travel in old age. As preparation for old age is insufficient, policy attention is required for the younger generation as a new generation. In this paper, focusing on the baby boom generation, the definition of the opal generation, their consumption lifestyle, attitudes, social activities, leisure activities, and lifestyle such as health efforts are investigated, and job creation, social re-education, and local It is intended to present practical measures for preparing for old age, such as the establishment of medical facilities and social consideration for a leisurely cultural life.

Nowadays, remodeling cases for some apartment like Hyundai through the support of government are reported. Conventionally, balcony and aisle are extended for additional private area or balcony which is supported by new frame is extended. In extension work at site, dowel bar is conventionally inserted in old concrete slab for connection with old and new slab, however, an examination for structural safety is rarely performed prior to construction, if ever, vertical load is only considered for structural analysis. When conventionally connected structures are exposed to earthquake, the old and new structures have individual earthquake behavior with different mode, which may lead the elimination of resistance to earthquake in new structures. As of this reason, new detailing connection system which can have light weight and sufficient ductility performance is developed for application to domestic extension works. Additionally, user manual and specification are also developed for fertilization of application for the developed technology.

The purpose of this study was to evaluate the urban park and the green spaces within the public service framework. It was investigated by identifying the priority elements as defined by the residents and to figure out the differences of residents' satisfaction for the parks in new and old downtown. This study surveyed 455 residents from 80 dong (neighborhoods) of 5 Gu(districts) in Daejon. In this study, satisfaction on the urban parks and the green spaces in the old downtown was compared with the new town area. The results were as follows: Those who lived in the new downtown areas showed higher satisfaction than those in the old downtown for the urban parks and the green spaces, as well as in all 8 other evaluation sections. Both new and old downtown residents scored high on the 'city landscape and the natural environment' and 'green spaces and facilitats' items, but scored low on 'citizen's respect' and 'acceptance of resident opinions'. The old downtown residents highly valued on easy access to the parks, while the new downtown residents focused on various activities and programs, as well as resident participation, as the parks. The variables affected the resident's satisfaction on the urban parks in old downtown areas consisted of 'information', 'diversity', 'supply decision'. Among these variables, 'diversity' had the most significant influence on the satisfaction level.
