  • The purpose of this study is to provide the fashion industry in Korea with materials that could enhance its international competitiveness by suggesting marketing strategies for fast fashion brands after taking product, price, place, and promotion into consideration. The product strategy should focus on developing products that accurately reflect the general market trend and consumer demand, selecting optimal materials, and pursuing internal production. This, coupled with strategic cooperation with designers, will ensure reliable quality and enhance the brand image. The pricing strategy should place greater emphasis on reducing production costs. Diverse task outsourcing and design competition, for instance, can lower the cost of design development. The place strategy should be set according to the operation of a systematic and efficient distribution system based on SPA, an automatic delivery system, sales or return system, speed control system, and a value chain that consists of horizontal business alliances. The promotion strategy should be run under the central control of the headquarters using various unique VMDs. Furthermore, online marketing campaigns, spectacular fashion shows, design competitions, catalogue marketing campaigns, and other new sales promotion schemes could all be introduced.

  • This study aims at analysing the process of introduction and the development of the agri-environment policy of the UK and identifying the implication for the Korean government. The UK introduced the AES policy in order to reduce the negative impact of the farming practice on biodiversity and habitats. The initial process was only possible for the enormous research results on the relationship between the farming and environment. Since the UK launched the ESA scheme in 1987, it has extended the designated areas for four stages. Based on the success of the ESA scheme, it started CSS and other schemes. However, these had a modest success and were integrated into the CSS scheme, which from then on became the main measures of the AES in the UK. The whole process of the UK case tells us that the most important work for the start of the AES in Korea would be the necessity and feasibility of the environment protection measures in Korea which could be identified from academic and scientific research on the impact of agricultural practice on the rural environment in Korea.

  • Biological sequences such as DNA and amino acid sequences typically contain a large number of items. They have contiguous sequences that ordinarily consist of more than hundreds of frequent items. In biological sequences analysis(BSA), a frequent contiguous sequence search is one of the most important operations. Many studies have been done for mining sequential patterns efficiently. Most of the existing methods for mining sequential patterns are based on the Apriori algorithm. In particular, the prefixSpan algorithm is one of the most efficient sequential pattern mining schemes based on the Apriori algorithm. However, since the algorithm expands the sequential patterns from frequent patterns with length-1, it is not suitable for biological datasets with long frequent contiguous sequences. In recent years, the MacosVSpan algorithm was proposed based on the idea of the prefixSpan algorithm to significantly reduce its recursive process. However, the algorithm is still inefficient for mining frequent contiguous sequences from long biological data sequences. In this paper, we propose an efficient method to mine maximal frequent contiguous sequences in large biological data sequences by constructing the spanning tree with a fixed length. To verify the superiority of the proposed method, we perform experiments in various environments. The experiments show that the proposed method is much more efficient than MacosVSpan in terms of retrieval performance.

  • The Yellow River Basin located in the Northern part of China is well-known not only as the seriously limited water sources but the greatest sediment-carrying stream in the world. The observed annual average sediment concentration in this area is $37.6kg/\textrm{mm}^3$, and 3.1% of the water volume is occupied by sediments. Due to the reason, water development has been extremely limited and it has been appeared as one of the most difficult problems in reservoir development and management. The major obstacle to surface water uses is reservoir sedimentation so that it has been strongly requested to seek the method managing sediment by optimal fashion. To solve this problem, KOWACO (Korea Water Resources Corporation) has developed various methods on the optimal reservoir management schemes including sediment management for the Upper Fenhe Basin Reservoir System at the cooperation project with Chinese. Information Variable Dynamic Programming. which is one of them, was developed for the reservoir sediment management and a set of non-dominated solutions are generated to choose the best alternative in water supply and reservoir sediment objective problem.

  • Purpose Due to the complexity of policy environment in modern society, it is accepted as common basics of policy design to mix up a variety of policy instruments aiming the multiple functions. However, under the current situation of written-down policy specification, not only the public officers but also the policy researchers cannot easily grasp such frameworks as policy portfolio. The purpose of this study is to develop "Policy Attributes Taxonomy" identifying and classifying the public programs to help making decisions for allocative efficiency with effectiveness-based information. Design/methodology/approach To figure out the main scheme and classification criteria of Policy Attributes Taxonomy which represents characteristics of public policies, previous theories and researches on policy components were explored. In addition, to test taxonomic feasibility of certain information system, a set of "Feasibility Standards" was drawn from "requirements for well-organized criteria" of eminent taxonomy literatures. Finally, current government classification system in the area of social service was tested to visualize the application of Taxonomy and Standards. Findings Program Taxonomy Schemes were set including "policy goals", "policy targets", "policy tools", "logical relation" and "delivery system". Each program and project could be condensed into these attributes, making their design more easily distinguishable. Policy portfolio could be readily made out by extracting certain characteristics according to this scheme. Moreover, this taxonomy could be used for rearrangement of present "Program Budget System" or estimation of "Basic Income".

  • Purpose : The purpose of the present study was to evaluate postoperative stability and soft-tissue osseous relations of the long face syndrome patients. Methods : Twenty-five patients who had undergone bimaxillary surgery to correct long face syndrome at the Pusan National University Hospital were evaluated. The lateral cephalograms of preoperative, 1 week postoperative and at least 1 year postoperative were examined. Results : 1. The facial height of the long face syndrome patients were longer than normal Korean adults. 2. The most common malocclusion type of the long face syndrome patients in Korea was class III. 3. Horizontal postoperative skeletal relapses were $-0.64{\sim}0.80mm$ in the maxilla, and $-0.56{\sim}0.48mm$ in the mandible. 4. Vertical postoperative skeletal relapses were $0.20{\sim}0.56mm$ in the maxilla, and $-0.80{\sim}0.20mm$ in the mandible. 5. Postoperative soft tissue changes in long face syndrome patients were correlated with postoperative skeletal changes. So prediction schemes for postoperative soft-tissue changes were obtainable. Conclusion : It is hard to predict the exact direction and quantity of the postoperative skeletal relapse in long face syndrome patient's orthognathic surgery because of large standard deviation. But soft tissue change is predictable via prediction scheme.

  • The threads of this thesis are several theoretical issues of modern urban ideals. Modern architects and urban designers conceived their individual artifacts, which assumed to be laid out on the new settings totally different from the existing urban fabrics derived from inherently medieval ones. In the discussion of modern ideal society, the Industrial Revolution and the Enlightenment was a pivotal point. Innovations in technology and expanded living territories since the double revolution have been critical factors in the evolution of new ideas of urbanism. The tremendous success in science and technology led a way to the 'science-fiction' environment as a destined apocalyptic world. The dream, whether it was socialist or in any other believes, to a pastoral utopia beyond the capitalist society was represented through the ideal cities, which were modern versions of arcadia in the other approaches. Two sides of revolutionary ideas are presented as a futurist city and a garden city, which are on the separate notions but co-existed or overlapped in a single urban project such as in Le Corbusier urban schemes or even Tchumi's recent work, Parc de la Villette. Urban ideas in the twentieth century are based on urban naturalism, the notion of which was consistant from abbe Laugier to Le Corbusier, as well as machine aesthetics interpreted in terms of archeological research and modern technology.

  • MacCormack's method is an explicit, second order finite difference scheme that is widely used in the solution of hyperbolic partial differential equations. Apparently, however, it has shown entropy violations under small discontinuity. This non-physical shock grows fast and eventually all the meaningful information of the solution disappears. Some modifications of MacCormack's methods follow ideas of central schemes with an advantage of second order accuracy for space and conserve the high order accuracy for time step also. Numerical results are shown to perform well for the one-dimensional Burgers' equation and Euler equations gas dynamic.
