The fault diameter is one of the important measures for transmission rate and reliability of interconnection network. H.-O. Lee et al.[Parallel paths in folded hyper-star graph, Journal of KIPS, Vol.6, No.7, pp.1756-1769, 1999] suggested the node-disjoint paths of FHS (2n,n), and proved that the fault diameter of FHS(2n,n) is less than 2n-1. In this paper, we suggest an advanced node-disjoint paths of FHS(2n,n). We also prove that the wide diameter of FHS(2n,n) is dist(U,V)+4, and the fault diameter of FHS(2n,n) is less than n+2.

WBI provides new opportunities to realize the flexible learning environment based on hypermedia and to support distance learning with a diverse interaction. The instructors or learners in WBI claim to be able to resolve reluctant fluctuations such as disorientation and cognitive overload. To overcome these phenomena, a supplementary tool able to manage learning space organized by the instructor's or learner's own way and offer effective navigation techniques is presented in this paper. A learning space management and navigation tool called HyperMap dynamically represents the learning space in the form of a two-dimensional labeled graph. This HyperMap also can be used for an instruction design tool, learner's portfolio for the exchange of learning experiences. and the assessment of WBI.

본 논문에서는 인공지능 신경망의 하이퍼 파라미터들이 그래프 신경망 모델의 성능에 미치는 영향을 알아보기 위하여 대규모 그래프 데이터를 기반으로 이진 분류 문제를 예측하는 그래프 합성곱 신경망 모델(Graph Convolution Network Model)을 구현하고 모델의 다양한 하이퍼 파라미터 중 손실함수와 활성화 함수를 여러 가지 조합으로 적용하며 모델 학습과 예측 실험을 시행하였다. 실험 결과, 활성화 함수보다는 손실함수의 선택이 모델의 예측 성능에 좀 더 큰 영향을 미치는 것을 확인하였다.

The equality relation is very important in mechanical theorem proving procedures. A proposed inference rule called RHU-resolution is intended to extend the hyperparamodulation[23, 9] by introducing a bidirectional proof search that simultaneously employs a forward reasoning and a backward reasoning, and generalize it by incorporating beneflts of extended hyper steps with a preprocessing process, that includes a subsumption check in an equality graph and a high level planning. The forward reasoning in RHU-resolution may replace the role of the function substitution link.[9] That is, RHU-deduction without the function substitution link gets a proof. In order to control explosive generation of positive equalities by the forward reasoning, we haue put some restrictions on input clauses and k-pd links, and also have included a control strategy for a positive-positive linkage, like the set-of-support concept, A linking path between two end terms can be found by simple checking of linked unifiability using the concept of a linked unification. We tried to prevent redundant resolvents from generating by preprocessing using a subsumption check in the subsumption based eauality graph(SPD-Graph)so that the search space for possible RHU-resolution may be reduced.

Interactive storytelling is a scenario created "on the fly" with digital content through user interaction. Every time interaction occurs between the user and content, a brand new story is created. Interaction intrigues people because it provides different story from same content. Through conventional media, people shared same content and experience. However through interactive media, people encounter unique experience, over same content possibly everytime they use it. People we, by their nature, very interactive being. However, interacting with media is not an activity that people are accustomed to. Hence, designing content has been all migrating experience from existing media to an unfamiliar ground. Unique and adoptive ways of designing content for digital interactive media is being sought out from the need as the result of the evolution of integrated society and emerging information technology. People are already used to some of interactive storytelling through hyper text in CD-ROM and web sites. More complicated and different structured models were born through games that offered graphics, virtual spaces and interactivity. When drawn onto a structural graph, few attributes and similarities seem to occur. This paper will try to outline and discuss structural graphs of interactive storytelling methods and suggest some ways for better storytelling design.

This paper proposed dynamic adaptive model based on discrete probability distribution function and user profile in web based HyperMedia educational systems. This modelsrepresents application domain to weighted direction graph of dynamic adaptive objects andmodeling user actions using dynamically approach method structured on discrete probability function. Proposed probabilitic analysis can use that presenting potential attribute to useractions that are tracing search actions of user in WebMedia structure. This approach methodscan allocate dynamically appropriate profiles to user.

폴디드 하이퍼스타 FHS(2n,n)은 하이퍼큐브와 그의 변형된 그래프보다 망 비용이 개선된 상호연결망이다. 본 논문에서는 폴디드 하이퍼스타 FHS(n-1,k-1)와 FHS(n-1,k) 그래프를 연결하여 폴디드 하이퍼스타 FHS(n,k)를 생성하는 방법을 제시하였다(단, n=2k). 또한, 정규 연결망 형태인 폴디드 하이퍼스타 FHS(2n,n)의 노드연결도는 n+1이고, 최대고장허용도를 가짐을 보인다.

These days, citizens have made change of food life to take Western style food and to suffer from diabetes because of excessive nutrition taking, less exercise, stress and other environmental factors. They may suffer from diabetes because of genetic defect, surgery of pancreas, disinfection and medicine and others. One of ten Koreans may have symptom of diabetes to be popular. The diabetes that is a kind of metabolic disease has high blood sugar at disorder of hyper insulinism and/or defect of insulin action. Long time high blood sugar may produce chronic disease of kidney, eyes, nerve, heart and blood vessel and others. The purpose of health care of diabetes patient was to reach target blood sugar by diet, physical exercise and medicine and to prevent and delay complication. Diabetes patient shall control blood sugar to keep healthy. The blood sugar control requires time and effort, and all of the patients are difficult to make effort and to spend time. You can control blood sugar by the application. The application allows patients to control blood sugar and to save time and efforts and to make small sized input and automation of remaining area. The service was limited to blood sugar graph, and user carries smart phone to conduct test and to have difficulty. Further study needs to solve the problems and to investigate blood sugar testing not carrying smart phone and to make application of easy control of blood sugar.
