  • Several new versatile two-dimensional p-version finite elements are developed. The element matrices are integrated analytically to guarantee the accuracy and monotonic convergence of the predicted solutions of the proposed p-version elements. The analysis results show that the convergence rate of the present elements is very fast with respect to the number of additional Fourier or polynomial terms in shape functions, and their solutions are much more accurate than those of the linear finite elements for the same number of degrees of freedom. Additionally, the new p-version plate elements without the reduced integration can overcome the shear locking problem over the conventional h-version elements. Using the proposed p-version elements with fast convergent characteristic, the elasto-plastic impact of the structure attached with the absorber is simulated. Good agreement between the simulated and experimental results verifies the present p-version finite elements for the analyses of structural dynamic responses and the structural elasto-plastic impact. Further, using the elasto-plastic impact model and the p-version finite element method, the absorber of the T structure on the Qiantang River is designed for its collision protection.

  • 1. Purpose Lee Je-Ma had continued to revise "Donguisusebowon" by adding the contents of the Symptomatic-pharmacology(病證藥理論) on Soeumin, Soyangin and Taeeumin to it from the first establishment of the old version in 1894 to 1900.(new version). This paper tries to find out the contents and meaning of the Discourse on the Constitutional Symptoms and Diseases(病證論) between the old version and new version and what the Discourse on the Constitutional Symptoms and Diseases affected the Theory of Eight Constitution created in subsequent years. 2. Methods I classified the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" into old version and new version and tried to find out the Theory of Eight morbidities(8病證論) which is the predecessor of the Theory of Eight Constitution, before reviewing their relation. 3. Conclusions 1) The Discourse on the Constitutional Symptoms and Diseases in the old version specify that the externally sensed diseases are caused by the deep sediment of nature(性) and that the internally touched diseases are caused by the violent activities of emotion(情). In addition, it said that all diseases are caused by the specific characteristics of patient's smaller internal organs(偏小之臟). But in new version, the diseases were understood through the concept Exterior, Interior, Heat and cold(表裏寒熱). The new version said that the diseases may be caused not only the specific characteristics of patient's smaller organs but also by bigger organs(偏大之臟). 2) The Theory of Eight Constitution was derived from the Theory of Eight morbidities, in which all kinds of human diseases are caused by 8 disease-orgin organ and that the diseases therefore can be classified into 8 morbidities. The Theory of Eight morbidities reorganized the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" by classifying them into first morbidity and second morbidity. 3) The Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" has decisively affected the creation of the Theory of Eight morbidities which is the predecessor of the Theory of Eight Constitution. The Theory of Eight morbidities may be deemed another interpretation of the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon". As the Theory of Eight morbidities put emphasis on the genetic characteristics, the Theory of Eight Constitution stating that Eight morbidities are caused by different specific constitution was derived.

  • Recently, business environments have been changing quickly. To establish competitive advantage, most enterprises have been using information systems such as Enterprise Resource Planning (ERP), Supply Chain Management (SCM) and Customer Relationship Management (CRM). Many consider Business Process Management (BPM) a new innovative solution for enterprise-wide processes. As the BPM system is used more widely and matures, new techniques and functions will be developed by commercial vendors. However, they mainly focus on correctly executing process models, and user convenience has not been considered. In this paper, we have developed a new method of designing business processes, which provides users with an easy modeling interface. The method is based on version management. Version management of a process enables a history of the process model to be recorded. In order to prevent wasted storage, not all of the process versions are stored. An initial version and changes to each process are stored by automatically detecting changes. Our method enhances the convenience of the modeling business processes and thus helps the process designer. A prototype system is presented to verify the effectiveness of our method.

  • Ontology has an important role in semantic web to construct and query semantic data. When system make changes to ontologies, questions arise about versioning of these changes. Applying this changes on a dynamic environment is even more important. To apply these changes, change specification method is needed. Early studies show RDF-based syntax for the operations between old and new ontologies. When several ontology versions can be used for some query, if possible, using possible newest version ontology with prospective use is best way to process the query. Prospective use of ontology means using a newer version of an ontology with a data source that conforms to a more recent ontology. In this paper, for prospective use of ontology version, structure of change specification of class and property through several ontology versions is proposed. From this, efficient adaptive ontology version selection for a query can be possible. Algorithm for structure of version transition representation is proposed and simulation results show possible newest version number for queries.

  • Sourcing Simulator is specialized form of software capable of providing great insight into merchandising decision making. It is relatively easy to learn and operate by reading the help menus, experimenting with inputs, and critically analyzing outputs. 1 see that it has great potential in a training program for new merchandisers to help them absorb the complexity of the numbers they must effectively use. The Sourcing Simulator, Version 1 that accompanies my textbook, Merchandising: Theory Principles, and Practice, 2nd ed. is the least complex version available. Two versions are available from [TC]2 - Retail version and The Retail/ Manufacturing version. The Retail Version is very similar to the Version 1. The Retail/ Manufacturing Version includes analysis of processes and costs in the manufacturing process as well as the merchandise planning component that we have discussed here. Sourcing Simulator is developed at North Carolina State University by Dr. Russ King, and available from Textile Clothing Technology Corporation $[TC]^2$, Cary, North Carolina.

  • 본 연구는 2008년 이후 본격적으로 진행되고 있는 음식과 관련된 스토리텔링에 대한 연구를 고찰하여 내용을 분석하였다. 이를 바탕으로 음식을 매개로 소비자와 소통할 수 있는 새로운 스토리의 구성 전략에 대해 논하고자 한다. 그간 스토리텔링의 연구를 살펴보면 스토리의 소재 발굴 및 필요성 강조의 연구, 스토리를 통한 음식 개발 및 관광 상품화 방안을 제시하는 연구가 주를 이루었다. 또 스토리텔링에 의한 소비자의 태도를 살펴보는 연구가 서서히 진행되고 있으나 음식 관련 스토리를 창작하기 위한 스토리의 내용 구성에 대한 연구는 전무한 실정이다. 따라서 오늘날까지 전해져 내려오는 또는 새롭게 창작된 스토리를 내용에 따라 version 1.0, 2.0, 3.0으로 나누어 분석하였으며, 최종적으로 우리가 앞으로 지향해야할 음식 스토리텔링의 새로운 version 4.0을 제시하고자 한다. 이는 음식 스토리텔링 창작 분야의 새로운 패러다임을 제공하게 될 것이다.

  • 선형탄성파괴역학에서 특히 균열 쉘의 응력집중계수 산정을 위해 p-version 유한요소법에 기초한 선진유한요소기법이 제안되었다. 세가지 균열된 쉘 예제를 통해 응력집중계수 산정은 종래의 h-version 유한요소모델에 비하여 p-version 유한요소 모델이 수렴성과 정확도 면에서 훨씬 더 적합함을 보여주고 있다. 이 기법의 주요 이점은 근사해의 정확도가 요소분할이나 균열선단요소 또는 혼합형 변분원리등의 특별고려가 없이 확보될 수 있다는데 있다.

  • 현재 사용가능한 측위위성은 GPS외에도 GLONASS, GALILEO, BeiDou, QZSS등으로 다양해 졌다. 그러나 측위 정확도를 높이는 보강 서비스인 Differential GPS는 RTCM 버전 2.3 표준을 따르고 있어 GPS에 대한 보정정보만을 서비스할 수 있다. 이에 RTCM에서는 모든 위성에 대한 보정정보를 사용자에게 서비스할 수 있도록 RTCM 버전 2.4표준을 제정하고 있다. 한국의 DGNSS 기준국은 소프트웨어로 제작된 시스템이 설치되어 있어 새로운 표준에 빠르게 대응할 수 있다. 그러나 현재의 RSIM 1.3기반 DGNSS 기준국시스템의 아키텍처는 동시에 여러 GNSS의 보정정보를 생성하지 못하고, RTCM 2.4 역시 지원하지 못한다. 따라서 본 논문에서는 RTCM 버전 2.4 표준을 분석하고 소프트웨어 DGNSS 기준국 시스템이 RTCM 버전 2.4 표준에 맞춰 동시에 여러개의 GNSS에 대한 RTCM 보정정보 메시지를 생성할 수 있도록 하는 아키텍처를 설계하였다.

  • 정확한 홍수빈도와 강도의 추정은 홍수위험관리 및 피해감소에 중요한 역할을 담당하고 있다. 미국에서는 설계수문량 산정을 위한 Log Pearson Type-III (LP-III)와 매개변수 추정을 위한 모멘트법을 일괄적으로 적용해오고 있다. 1965년 홍수빈도해석 가이드라인인 Bulletin 15가 처음으로 만들어진 이후 이를 개량해 나아가 현재에는 Bulletin 17B가 가이드라인으로 사용되고 있다. 최근에 Bulletin 17C가 기존 가이드라인의 부족한 부분을 보완하고 새로운 방법들을 흡수하여 거의 완료상태에 있고 곧 출시될 예정이다. 본 연구에서는 새로이 보완된 Bulletin 17C에 대한 중요사항들을 분석하고 이를 적용하여 보았다. 분석결과들로부터 우리나라 설계홍수량 산정방법 및 절차의 개선방안에 대하여 고찰하였다.
