The purpose of this empirical study is an index to usage of export assistance programs for korean small-medium exporters. Build around the index make an analysis of SMEs internal or exterior factors have an effect on export at present or in future export performance and the relative importance. Based on 128 surveys form korean SMEs experienced export assistance programs, 8 hypotheses, which are set up each factor, were verified through the practical analysis. The main result of hypothesis drawn by empirical study are as follows : The more SMEs use the programs, the more high export performance at present and in future. Export competitive factor reject at present export performance, but it will affect future export performance. A size of the firm in the characteristics of SEMs will affect export performance. Export rate of own brand will not affect performance. Another factors show adoption partly concerned hypothesis. Classified exterior factors of SMEs, a intensity of market competition shows adoption partly concerned hypothesis. Market growth rate will affect export performance at present and future strongly. Finally the usage of assistance programs will affect between a consumption goods and an industrial goods differently. From this study we found if we want to develop the export assistance programs that can actually in phases help the SEMs.

The Mobile Mapping System is an effective method to acquire the position and image data using vehicle equipped with the GPS (Global Positioning System), IMU (Inertial Measurement Unit), and CCD camera. It is used in various fields of road facility management, map update, and etc. In the general photogrammetry such as aerial photogrammetry, GCP (Ground Control Point)s are needed to compute the image exterior orientation elements (the position and attitude of camera). These points are measured by field survey at the time of data acquisition. But it costs much time and money. Moreover, it is not possible to make sufficient GCP as much as we want. However Mobile Mapping System is more efficient both in time and money because it can obtain the position and attitude of camera at the time of photographing. That is, Indirect Georeferencing must use GCP to compute the image exterior orientation elements, but on the other hand Direct Georeferencing can directly compute the image exterior orientation elements by GPS/INS. In this paper, we analyze about the positional accuracy comparison of ground point using the Direct Georeferencing and Indirect Georeferencing.

Recently, buildings with transparent glazing on exterior walls have increased. The transparent glazing on exterior walls gives an impression of opening through introducing external environment's elements to inside of the building, and has various merits and so on, but has defects in controling indoor environments. Especially, the excess of solar radiation in summer increases cooling load causing discomforts to occupants providing radiant environment with high temperature. Cooling load mainly depends on electricity comparing to heating load and intents to centralize specific time. So it is necessary to work out a countermeasure. In this study, showed P building with transparent glazing on exterior walls as a case, investigated indoor thermal performance, numerical analysis of P building in summer through comparing dry-sauna which is represented as radiant environment with high temperature. In the results of this study, transparent glazing space has radiant environment with high temperature such as dry-sauna because of the excess of solar radiation. Accordingly countermeasures are considered in building planning. As concrete methods, there are adiabatic effects using double glazing, use of sunscreen, blind, ventilation facilitation using natural draft, decrease of surface temperature through evaporation cooling and cooling coils.

Lately, the use of the NAT has become unavoidable with the increase of P2P traffic along with the exhaustion of IPv4 IP address. Due to NAT properties, NAT's internal host can only be connected through a relay method using the outside server. Accordingly, there is a lot of resource exhaustion of the relay server on the NAT exterior and network traffic increases. This essay proposes a topology that can form sessions to the NAT interior from the NAT exterior and that will decrease network traffic by placing NAT exterior relay servers in the NAT interior.

Current codes recommend large amounts of shear reinforcement for reinforced concrete beam-column joints that causes significant bar congestion. Increase in congestion of shear reinforcement in joint core (connection zone), leads to increase accomplishment problems. The congestion may also lead to diameter limitations on the beam bars relative to the joint dimensions. Using double headed studs instead of conventional closed hoops in reinforced concrete beam-column joints reduces congestion and ensures easier assembly of the reinforcing cage. The purpose of this research is evaluating the efficiency of the proposed reinforcement. In this way, 10 groups of exterior beam-column joints are modeled. Each group includes 7 specimens by different reinforcing details in their joint core. All specimens are modeled by using of ABAQUS and analyzed subjected to cyclic loading. After verification of analytical modeling with an experimental specimen, 3D nonlinear specimens are modeled and analyzed. Then, the effect of amount and arrangement of headed studs on ductility, performance, ultimate strength and energy absorption has been studied. Based on the results, all joints reinforced with double headed studs represent better performance compared with the joints without shear transverse reinforcement in joints core. The behavior of the former is close to joints reinforced with closed hoops and cross ties according to the seismic design codes. By adjusting the arrangement of double-headed studs, the decrease in ductility, performance, ultimate moment resistant and energy absorption reduce to 2.61%, 0.90%, 0.90% and 1.66% respectively compared with the joints reinforced by closed hoops on the average. Since the use of headed studs reduces accomplishment problems, these amounts are negligible. Therefore, use of double-headed studs has proved to be a viable option for reinforcing exterior beam-column joints.

Sokmyeungtang was the representative prescription for Apoplexy under the rule of Tang and Song dynasty of which the cultures were thriving in the history of China. However, the clinical use of Sokmyeungtang has been gradually reduced since Geumwon dynasty of China because it was misunderstood that the dryness heat drugs of pungent in flavor and warm in property such as Ephedra, Pubescent Angelica Root, Chinese Cassia Tree-Bark, Divaricate Saposhnikovia Root, Prepared Aconite Root, Fresh Ginger, and Wildginger Herb included in the presciption for Apoplexy supplemented heat as damaging Yin flood. In fact, the drugs pungent in flavor and warm in property activate exterior and interior circulation, circulate channels and collaterals, promote blood circulation, and remove blood stasis with the side effect of relieving exterior syndrome with drugs warming channels. When treating Apoplexy with Sokmyeungtang, the cold drugs such as Gypsum, Baikai Skullcap Root, and Pueraria Root are prescribed to suppress fire of pungent dryness and to control excessive heat of people with Apoplexy as reducing the effects of hot drugs causing impairment of Yin. For treatment of Apoplexy, the above drugs accelerate blood and Qi circulation in channels and collaterals and then in necrotic tissue of human body as removing blood stasis. Consequently, these drugs improve disorders of capillary tube circulation. If Sokmyeungtang, an old prescription, is properly understood, it will be substantially helpful to all kinds of treatments in clinical cases

This study was intended to investigate the contemporary meaning of transparent design expressed in contemporary fashion by inquiring into its plasticity expressed in contemporary design and fashion and analyzing the association between them. It used the comparative anesthetic method widely used by H. W lfflin and other scholars in eliciting the differences and similarities in styles. It attempted to investigate the plasticity of transparent design expressed in contemporary design by dividing it into the epidermal, spatial and ideological effects. Contemporary design expressed the epidermal effects such as lightness(nimbleness), smoothness, contrast and stress It expressed the spatial effects such as spatial flexibility through the interpenetration of interior and exterior spaces, expansion of the space and the like. And it expressed ideological effects such as openness, pureness, playfulness and the like. In terms of lightness, contemporary design expressed actual or visual lightness by using transparent materials. In terms of the interpenetration of interior and exterior spaces, it expressed the interpenetration of the interior space into the exterior spaces and vice versa. In terms of spatial expansion, contemporary design expressed the infinite spatial connection by drawing the exterior space into the interior space. Contrast and stress were formed by imposing visual unity on contemporary fashion by using opaque and transparent materials. In terms of openness, contemporary design expressed contemporary people's candor and dependability by making the inside of the building or object look outward. To express pureness, contemporary design used the clear and transparent image by using the glass or translucent materials taking on the pure property. To express playfulness, contemporary made use of the vagueness of the spatial boundary, the locational switching of inner and outer spaces, and interesting external forms occurring when light pass through opaque and transparent materials.

In recent years, the architectural interest in the apartment design has been getting focused on qualitative improvement and design differentiation. Especially the facade design differentiation is one of the most important elements in this matter. The purpose of this study is to provide the basic informations that can be referenced when architects are dealing with exterior design by analyzed design types and characteristics of apartment entrances. Target apartment of this study was whasung dongtan the 2nd phase new city districts which was planned to solve a housing shortage in the capital region. Having examined eleven pilot districts, four 1st construction areas, and eight 2nd construction areas, - total 23 complexes - 282 apartment entrances in 212 apartment buildings were carefully researched. Apartment entrance design can be divided into 15 different design elements: design types and combination types, direction, shape, height, approach types, exterior wall finishes of entrance, exterior wall finishes of lower parts of apartment, handrail types of slope, floor finishes of slope, distribution ratio of piloti, ceiling height of piloti, floor finishes of piloti, space use of piloti, window establishment between piloti and elevator hall, landscape elements of piloti. Design characteristics of building entrances were also analyzed in 4 groups (I, II, III, IV) divided by construction contractors ranking. In conclusion, first, design types and combination types can be classified into 15 different kinds, and the group I and II tend to show wider variety of entrance combinations. Secondly, the height and volume of extrude entrance type tend to increase in the group I and II. Third, the spatial configuration of pilotis appears to show more of 'pass + store + break' rather than 'access', as we get closer to the group I.
