본 논문에서는 e-비즈니스 DTD(Document Type Definition) 문서를 기반으로 한 XML 폼 생성기(Form Generator)를 설계 및 구현하였다. 인터넷 보급과 정보환경 변화는 e-비즈니스에 있어서 많은 변화를 제공하였고, 거래에 사용될 비즈니스 문서 양식에 있어서도 웹 형식이거나 전자화된 전용 양식 형태로 변환될 필요가 있게 되었다. 이러한 상황에서 각각의 업체별로 다양한 문서 포맷을 사용하여, 상호주체 간에 포맷 호환성 제공을 위한 필요성이 제기되며, 따라서 재사용성과 포맷 호환성 지원에 따른 비용의 문제를 안고 있다. 이에 따라, 논문에서 제안하는 XML 폼 생성기는 XSLT를 이용하여, 생성 결과인 XML 폼 문서에 HTML(HyperText Markup Language) 형태의 웹 문서로 생성 후에, 사용자 입력을 통해 e-비즈니스 DTD 문서 구조에 유효한 XML 비즈니스 메시지를 작성할 수 있다.

The nuclear power plant's turbine-generator system had been suffered form some problems, such as high shaft vibration, generator casing crack, stator coil water leakage, high $H_2$ gas consumption rate. Those kinds of problems were related to high vibration. So nuclear plant decided to replace generator in order to reduce rotor high vibration and high thermal sensitivity. A series of effort to reduce turbine-generator vibration was carried out as followings, first of all, replacement of generator, analysis of turbine-generator vibration, LP B rotor shop balancing, improvement of LP B/Gen coupling run-out, improvement of Generator basement and field balancing. Finally the nuclear turbine-generator's shaft vibration was reduced below $60{\mu}m$ from over $200{\mu}m$ which is very excellent vibration in nuclear turbine-generator in Korea.

Chaos theory, qualitative study of unstable aperiodic behavior in deterministic nonlinear dynamical systems, is dominant paradigm in the twenty first century. Fractal geometry, as an expressed form of chaos, now influences many areas such as architecture, art, music, economics, literature, etc. The purpose of this study is to analyze fractal geometry and fractal formative elements in architectural design. There are scaling, superimposition, distortion, deformation and repetition in the fractal form generator that can be applied to design concept and process in architecture. This study shows fractal geometry can be the architectural form creation method. Fractal geometry similar to nature's patterned order can be provided endless possibilities for design analysis and methodology in architecture. Therefore the further study of fractal geometry should progress synthetically through the basis of the study.

Key is generally formed using the Random Number. How to make the Random Number is to cast coin or dice as classical method, to form the Real Random Number with Hardware and to make the Pseudo Random Number by means of utilizing mathematical algorithm. This thesis presented NRNG(New Random Number Generator) which put self-development Hardware to use as Key Generation Method and inspected to compare the Real Random Number with the Pseudo Random Number and special properties which PRNG(Pseudo-Random Number Generator) creates.

In this paper, we propose the parallel scrambling technique which is applicable in the multibit-interleaved multiplexing environment. For this, we introduce the concept of SSRG (simple shift register generator) and MSRG(modular shift register generator), and investigate their properties. We also introduce the concept of PSRG(parallel shift register generator) - parallel form of shift register generator, and consider realizations of PSRGs based on SSRGs and MSRGs. Finally, we show how to apply PSRGs to the parallel scrambling for the SDH system.

The DSP silicon compiler consists of language compiler, module generator, placement tool, router, layout generation tools, and simulator. In this paper, The language compiler, the module generator, placement tool, and simulator were developed and provided for the system designer. The language compiler translates the designer's system description language into the intermediate form file. The intermediate form file expresses the interconnections and specifications of the cells in the cell library. The simulator was developed and provided for the behavioral verification of the DSP system. For its implementation, the event-driven technique and the C$^{++}$ task library was used. The module generator was developed for the layout of the verified DSP system, and generates the functional block to be used in the DSP chip. And then the placement tool determines the appropriate positions of the cells in the DSP chip. In this paper, the placement tool was implemented by Min-Cut and Simulated Annealing algorithm. The placement process can be controlled by the several conditions input by the system designer.

A high voltage and nanosecond Blumlein pulse generator has been developed to produce an output pulse whose voltage level is greater than 250 kV and pulse duration 5 ns. The generator consists of various components such as a charging circuit, a pulse transformer, and a spark gap switch. As a heart of the generator, a Blumlein pulse forming line has been constructed in the cylindrical form using three cylindrical aluminum electrodes that are placed concentrically. Unlike the ideal Blumlein line, the output pulse of an actual Blumlein line may be affected by stray inductances and capacitances of switching and charging components, thereby degrading the performance of the generator. In this paper, PSPICE simulations have been performed to examine effects of stray inductances and capacitances on waveforms of output pulses. Simulation results show that the pulse waveform is significantly distorted mainly by the stray inductance of the spark gap switch.

In [8], the author decomposed the Dirichlet form associated to a bounded generator G of a $weakly^*$-continuous, completely positive, KMS-symmetric Markovian semigroup on a von Neumann algebra M. The aim of this paper is to extend G to the unbounded generator using the bimodule structure and derivations.

XML은 점차 널리 사용되고 있지만, 일반 사용자가 편집기를 이용해서 XML 문서를 작성하기에는 아직 많은 어려움이 있다. XML 문서 중에서 상당 부분은 정형화된 데이타를 처리하기 위한 데이터 중심 XML 문서이며, 이러한 형태의 문서인 경우에 초보자도 폼(form) 형태의 GUI를 이용해서 쉽게 작성할 수 있다. 본 논문에서는 데이타 중심 XML 문서에 대해서 모델 기반으로 폼 형태의 XML 편집기를 자동적으로 생성할 수 있는 방법과 편집기 생성기인 XED를 소개한다. XML 문서의 DTD는 연속, 선택, 반복의 구조로 이루어져 있으며, 이러한 구조는 DDG (Document Decomposition Graph) 그래프로 표현될 수 있다. XED는 XML의 DDG에 사용자가 프리젠테이션 규칙을 적용함으로써 XML 편집기를 자동적으로 생성할 수 있고, 사용자가 생성된 편집기의 레이아웃과 GUI 속성을 직접 조작을 통해서 변경할 수 있는 방법을 제공한다.
