하나의 치아가 일부 파손되어 수복되어야 할 보철물을 인레이/온레이(Inlay/Onlay)라 한다. 본 논문에서는 3차원 메쉬 기반 모델에서 보다 정확한 인레이/온레이를 효과적으로 모델링하기 위한 기법을 제안한다. 인레이/온레이는 지대치와 접하는 내면과 밖으로 들어나는 외면으로 구성된다. 인레이/온레이의 내면 모델링은 2차원 다각선상의 Minkowski Sum 알고리즘을 이용하여 지대치와의 접합력을 확보한다. 그리고 미리 데이터베이스에 저장된 표준 치아 모델, 치과의사에 의해 만들어진 FGP(functionally guided plane) 및 메쉬의 변형 기법인 DMFFD(direct manipulation free-form deformation) 기법[16]과 MWD(multiple wires deformation) 기법[24]을 이용하여 외면을 모델링한다. 데이터베이스에 저장된 표준 치아는 인레이/온레이 외면의 형태를 결정하기 위해 사용되며, FGP는 환자의 인접면과 교합면의 특성을 반영하기 위해 사용되었다. 마지막으로 3차원 메쉬의 두 변형 기법인 DMFFD와 MWD 기법은 환자의 인접면과 교합면을 반영한 치아의 형태를 만들어 내기 위해 사용된다. 본 논문에서 제안한 방법은 인레이/온레이의 내면과 외면을 설계할 때 필요한 정보를 미리 설정하여 처리하므로 기존의 방법에 비해 짧은 시간에 보다 정확한 인레이/온레이를 설계할 수 있었다.

The primordial germ cells (PGCs) were transfected in vitro and expressed the exogenous RSVLTR/${\beta}G2$ plasmid, suggesting thaI PGC is a possible vector for direct gene transfer into the germ line. Transfection efficiency of cell suspensions containing PGCs was 1.5% by liposome mediated DNA transfection. By microinjection of the transfected PGCs into the host germinal crescent, PGCs migrated via blood vessel to the future gonad and these transfected PGCs resulted in the RSVLTR/${\beta}G2$ expression in the gonad. The results from the seeding of PGCs on the chorioallantoic membrane were insufficient to test the hypothesis that PGCs can penetrate or invade the chorioallantoic membrane for transport via the circulatory system.

In this paper we researched the homepage automation system and its implementation methods that made it possible for even the non-majors or the beginners to make a specific useful homepage with the simple manipulation of a mouse and the minimal input of necessary information. This system is the customer request-based homepage automation system that makes it possible with ease not only to manufacture homepage and install it on user specified server but also to maintain homepage without direct handling of homepage source.

Although visual programming is used in many fields of computer science and engineering, some dis-advantages can be found when they work together in an integrated programming environment. To overcome these shortcomings, there have been researches in combining multiparadigm with visual programming. However they have failed because they tried to combine the paramdigms without any coceptural model and structured method. In this paper, we investigate a new multiparadigm visual programming environment (MVPE), in which dataflow paradigm, form-based paradign, direct manipulation paradigm, and object-oriented paradigm are integrated together in an object-oriented way, based on the conceptual model of "method = paradigm, " This MVPE would overcome the limits of visual programming, and may also lead to the new discipline of visual programming environment.vironment.

The wing rock phenomenon is a high angle of attack aerodynamic motion manifested by limit cycle roll oscillations. Experimental studies reveal that direct control and manipulation of leading edge vortices, through the use of 'blowing' techniques is effective in the suppression of wing rock. This paper presents the design of a robust controller for the experimental implementation of one such 'blowing' technique - recessed angle spanwise blowing (RASB), to achieve wing rock suppression over a range of operating conditions. The robust controller employs Takagi - Sugeno fuzzy system, which is fine-tuned by experimental simulations. Performance of the controller is assessed by real-time wind tunnel experiments with an 80 degree swept back delta wing. Robustness is demonstrated by the suppression of wing rock at a range of angles of attack and free stream velocities. Numerical simulation results are used to further substantiate the experimental findings.

루트킷은 쉽게 말해 루트(root)권한을 쉽게 얻게 해주는 킷(kit)이다. 루트킷은 주로 운영체제의 커널 객체를 조작함으로서 프로세스, 파일 및 레지스트리가 사용자에게 발견되지 않도록 은닉하는 일을 수행한다. 본 논문에서는 루트킷의 은닉 기법중 하나인 직접 커널 오브젝트 조작 기법 (DKOM, Direct Kernel Object Manipulation)에 대해 연구한다. 그동안 루트킷에서 많이 이용되던 DKOM 기법은 작업 관리자로부터 프로세스를 은닉하는 일을 수행하였다. 그러나 본 논문에서는 이를 응용하여 작업 관리자로부터 프로세스를 은닉할 뿐만 아니라 Anti Rootkit 도구까지 우회하는 커널모드 디바이스를 설계하고, 이를 탐지할 수 있는 새로운 방법에 대하여 제안한다.

본 논문에서는 직접조작 방법을 이용하여 대화형 유전자 알고리즘(IGA)의 진화성능을 향상시키고 세대를 반복하면서 다양한 해를 얻을 수 있음을 NK-Landscape를 이용해 분석한다. 또한 NK모델을 이용하여 직접조작의 진화과정을 분석하기 위한 IGA 인터페이스를 생성한다. IGA를 이용한 진화는 특성상 적온 수의 개체와 세대수로 제한되기 때문에 지역해에 빠질 수 있는 문제점이 있다. 이러한 IGA 의 제약사창을 극복하는 방법으로 직접조작을 이용할 수 있으며 이 방법은 사용자가 원하는 개체를 생성할 수 있도록 진화과정에서 유전자를 직접 변경한다. IGA 에서 진화성능의 향상과 다양한 해외 생성을 분석하기 위하여 진화연산자인 교차, 돌연변이와 직접조작 방법의 성능을 비교 분석한다. Kauffman이 제안한 NK-Landscape로 진화과정에서 해공간이 얼마나 "ruggedness" 한지와 다양한 진화연산자에서 어떤 성능을 갖는지 분석할 수 있다 실험을 통해 3D 꽃 디자인 문제에서 NK-landscape기반 IGA인터페이스를 이용하여 IGA 해공간을 분석하고 교차, 돌연변이와 직접조작 방법의 성능을 비교함으로써 직접조작 방법으로 더 빠른 시간에 다양한 최적해를 찾을 수 있음을 알 수 있었다.

The study of Putin's Russia should be placed in a broad historiographical context, prevailing in the West. While in the beginning of the post-Soviet era, most observers believed that Russia would reach a Fukuyamian "end of history," the situation is quite different now. At present, Western observers see Putin's Russia as the manifestation of authoritarianism. While this assumption is undoubtedly true, it does not provide much insight into the regime's operational model. Here, a comparison with Renaissance and early modern Europe might provide a clue to the operational model of the regime. Similar to early modern European rulers, Putin limits the use of direct and wide use of force, preferring manipulation, corruption, and the targeted killing of his most important enemies. In foreign policy, Putin has tried to avoid wholesale conflicts and broadly uses mercenaries, whose relationships with the Kremlin are downplayed. The similarities between Putin's regime and early modern European regimes do not mean that their destinies will be the same. In Europe, the Renaissance led to centralized states, whereas in Russia, the "Renaissance" could well lead to the country's disintegration.

Planning support systems(PSS) add more advanced spatial analysis functions than Geographic information systems(GIS) and intertemporal functions to the functions of spatial decision support systems(SDSS). This paper reports the continuing development of a PSS providing a framework that facilitates urban planners and civil engineers in conducting coherent deliberations about planning, design and operation & maintenance(O&M) of water-distribution networks for urban growth management. The PSS using dynamic optimization model, modeling-to-generate-alternatives, value engineering(VE) and life-cycle cost(LCC) can generate network alternatives in consideration of initial cost and O&H cost. Users can define alternatives by the direct manipulation of networks or by the manipulation of parameters in the models. The water-distribution network analysis model evaluates the performance of the user-defined alternatives. The PSS can be extended to include the functions of generating sewer network alternatives, combining water-distribution and sewer networks, eventually the function of planning, design and O&H of housing sites. Capacity expansion by the dynamic water-distribution network optimization model using MINLP includes three advantages over capacity expansion using optimal control theory(Kim and Hopkins 1996): 1) finds expansion alternatives including future capacity expansion times, sizes, locations, and pipe types of a water-distribution network provided, 2) has the capabilities to do the capacity expansion of each link spatially and intertemporally, and 3) requires less interaction between models. The modeling using MINLP is limited in addressing the relationship between cost, price, and demand, which the optimal control approach can consider. Strictly speaking, the construction and O&M costs of water-distribution networks influence the price charged for the served water, which in turn influence the. This limitation can be justified in rather small area because price per unit water in the area must be same as that of neighboring area, i.e., the price is determined administratively. Planners and engineers can put emphasis on capacity expansion without consideration of the relationship between cost, price, and demand.
