From the year 2000 on, Seoul has aimed to be a fashion city, and thus has been supporting young designers through Seoul Fashion Creative Studio, Generation Next, Le Dome, Concept Korea, etc. London is famous for nurturing young designers through the joint help of government, schools and industries: Alexander McQueen, Christopher Kane and Peter Pilotto are successful cases. Therefore, this research aims to suggest a direction for policies aimed at helping young designers in the international market, on the basis of London's nurturing programs and ideas from a literature review and case studies. The results are below. Firstly, a step-by-step supporting program is recommended. Secondly, long-lasting, sustainable programs are considered essential to support designers after the end of their contracts. Thirdly, practical assistance is preferred to monetary funding in order to lighten the designers' lot and in the interests of transparency. The mentoring service should be strengthened for the designers to eventually become independent. The support should be tailor-made according to items. Fourthly, the supporting programs should be promoted. Fifthly, government and industries should collaborate. Sixthly, 'de minimis' against overlapped support should be legislated. For these, the change of supporting method can be helpful; an independent administrative organisation plans and collects funds from governments and companies. Through these programs and any subsequent studies, Seoul could become a fashion city where young designers play active roles at a global level.

This study estimated the size of ornamental fish market as the basis survey for the development of the ornamental fish industry in Korea. It presents improvement projects agendas for the development of the Korean ornamental fish industry by investigating the challenges of the ornamental fish industry and consumer awareness. First, looking at the size of the ornamental fish market, calculated on the basis of survey results, the size of ornamental fish market is analysed as 231.8 billion won. The actual ornamental fish market is presumed to be much larger than this considering unclear gross sales from e-commerce and group sales, goods excluded from the ornamental fish export, expensive ornamental fish transaction from smuggling are missing. Ornamental fish industry and consumer awareness survey results can be described as follows: First, revenue structure of the ornamental fish market depends on a handful of expensive purchasing group rather than on low-cost consumption group. Second, many members of the ornamental fish producers, wholesalers, road shops are small-scale. Third, the sale of aquarium fish and aquarium fish related supplies in road shop have different market structures. Fourth, ornamental fish consumption is in the ongoing recession. Fifth, ornamental fish industry hopes for expansion of distribution and Research & Development. Sixth, satisfaction of ornamental fish consumers is generally low. As described above, ornamental fish industry in Korea are vulnerable in the market structure and industry is small and the consumer's satisfaction degree is staying in the 'normal' level. If current state will continue, future consumption can be reduced. It is necessary to increase the competitiveness by using various method including reorganization of the structure of the ornamental fish industry even though it is hard to reach conclusion only with the results of the survey.

Objective: A national survey was conducted to assess orthodontic residents' current concepts and knowledge of cleft lip and palate (CLP) management in Korea. Methods: A questionnaire consisting of 7 categories and 36 question items was distributed to 16 senior chief residents of orthodontic department at 11 dental university hospitals and 5 medical university hospitals in Korea. All respondents completed the questionnaires and returned them. Results: All of the respondents reported that they belonged to an interdisciplinary team. Nineteen percent indicated that they use presurgical infant orthopedic (PSIO) appliances. The percentage of respondents who reported they were 'unsure' about the methods about for cleft repair operation method was relatively high. Eighty-six percent reported that the orthodontic treatment was started at the deciduous or mixed dentition. Various answers were given regarding the amount of maxillary expansion for alveolar bone graft and the estimates of spontaneous or forced eruption of the upper canine. Sixty-seven percent reported use of a rapid maxillary expansion appliance as an anchorage device for maxillary protraction with a facemask. There was consensus among respondents regarding daily wearing time, duration of treatment, and amount of orthopedic force. Various estimates were given for the relapse percentage after maxillary advancement distraction osteogenesis (MADO). Most respondents did not have sufficient experience with MADO. Conclusions: These findings suggest that education about the concepts and methods of PSIO and surgical repair, consensus regarding orthodontic management protocols, and additional MADO experience are needed in order to improve the quality of CLP management in Korean orthodontic residents.

Assuming krypton molecules adsorbed on graphite surface as 2D gas, the interaction energy of Kr-graphite and the Henry's constant are calculated analytically by the Fourier series expansion method. 2D virial cofficients, $B_{2D}$ and $C_{2D}$, are also calculated to obtain 2D equation of state, and hence adsorption isotherms. The isotherms so obtained are compared with experimental results reported by Putnam and Fort. The pairwise additivity of Lennard-Jones(12, 6) interaction energy is also assumed, and parameters therein are taken as; ${\varepsilon}_{gs}$/k = 70 K, ${\sigma}_{gs}$ = 0.35 nm, ${\varepsilon}_{gg}$/k = 170 K, and ${\sigma}_{gg}$ = 0.37 nm.

Complex warpage behavior of the electronic packages causes internal stress so many kinds of mechanical failure occur such as delamination or crack. Efforts to predict the warpage behavior accurately in order to prevent the decrease in yield have been approached from various aspects. For warpage prediction, silicon is generally treated as a homogeneous material, therefore it is described as showing no warpage behavior due to thermal loading. However, it was reported that warpage is actually caused by residual stress accumulated during grinding and polishing in order to make silicon wafer thinner, which make silicon wafer inhomogeneous through thickness direction. In this paper, warpage behavior of the single-side polished wafer at solder reflow temperature, the highest temperature in packaging processes, was measured using 3D digital image correlation (DIC) method. Mechanism was verified by measuring coefficient of thermal expansion (CTE) of both mirror-polished surface and rough surface.

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 manufacturing process of porous glass-ceramics by the filler method, the sintering behaviour of crystallizable glass powder mixed with various salts was studied and also the effects of precipitated crystal phases on the properties of porous glass-ceramics were investigated. Fine-grained crystallizable glass powder was homogeneously mixed with various slat having grain size 100~200 ${\mu}{\textrm}{m}$ and sintered for densification. After washing out the inorganic salt with distilled water, the porous sintered body was heat treated additionly for crystallization. The MgO-Al2O3-SiO2 base glass was used as crystallizable glass powder and the water soluble salts such as K2SO4 and MgSO4 were used as filler. When K2SO4 was used, leucite crystal phase was formed as a result of the ion exchange and porous glass-ceramics which exhibit high temperature resistance and high thermal expansion coefficient of 17$\times$10-6/$^{\circ}C$ could be obtained. On the contrary, when MgSO4 was used, only slight ion exchange is observed and $\mu$-cordierite and $\alpha$-cordierite crystal phases were formed and porous glass-ceramics which exhibit low thermal expansion coefficient schedule were determined with the results of DTA curves, thermal shrinkage curves and XRD patterns analysis. From DTA curves and thermal shrinkage curves, it was found that the sintering densification have been completed at the temperature range of exothermic peak for crystallization. The pore size distributions and pore diameters were measured by mercury porosimeter. The pore diameter of porous glass-ceramics was 10~15 ${\mu}{\textrm}{m}$ when 100~200${\mu}{\textrm}{m}$ grain size of K2SO4 was used and it was 25~30 ${\mu}{\textrm}{m}$ when the same grain size of MgSO4 was used. The porous glass-ceramics K2SO4 used shows bimodal pore size distribution and its porous skeleton structure was ascertained by SEM observation.

Clothing must have the individual beauty and the function that one can do one's body movement freely. therefore, from the human engineering view point, the exact measurement of the human body and the analysis of it's results must be applied to clothing because the arm works most. In this study, the skin surface of arm was investigated by shell made of Alginate of each movement. And by sometic method the rate of expansion and contraction of each section, inter-relation among the bust girth, axillary arm girth and scye girth and between the shoulder length right and the under axilla waist length were calculate4d. With these results, cap height, breadth of a sleeve and arm hole girth of existing sleeve pattern have been compared and analysed. The results are as follows; 1) According to the developmental figures of shell, the whole area change was small but that of shape was remarkable in M 4, 9, 13. The change of the Block 1 was particular. 2) Over arm length was contracted in all movements except M6 and under arm length expanded. The changes of sections a, b, c are large, while those of sections d, e are small. 3) In terms of latitudes, change of fore-arm region was small. The rate of scye girth varied from 14.3% of M13 to-5.6% of M2. The breadth of a sleeve expanded in all movements, and especially the front region expanded more than the back. 4) The relation between the shoulder length right and under axilla waist length, in all occasions, was contracted mutually, and one contracted, the other expanded. Therefore, in clothing construction when we consider the function of the arm it is better to widen the arm hole and the breadth of a sleeve at the same time than no widen the shoulder length by lowering the upper part of the upper side seam line.

This paper introduces a classification algorithm which can be applied to a learning problem with incomplete data sets, missing variable values or a class value. This algorithm uses a data expansion method which utilizes weighted values and probability techniques. It operates by extending a classifier which are considered to be in the optimal projection plane based on Fisher's formula. To do this, some equations are derived from the procedure to be applied to the data expansion. To evaluate the performance of the proposed algorithm, results of different measurements are iteratively compared by choosing one variable in the data set and then modifying the rate of missing and non-missing values in this selected variable. And objective evaluation of data sets can be achieved by comparing, the result of a data set with non-missing variable with that of C4.5 which is a known knowledge acquisition tool in machine learning.
