In this paper, XML form generator is designed and implemented on the basis of e-business's DTD (Document Type Definition) document. Rapid evolving for internet services and information infrastructure give many impacts on the e-business, it need to make a new kinds of web-based or electronic-based document formats for e-business transaction trading. In current situations, there are many kinds of document formats on conventional business documents for each companies. And, it has many problems on the aspects of the document reusability and cost to support interoperability between documents for the trading partners. To solve this interoperability of documents, the constructed XML form generator is changing XML form document into HTML (HyperText Markup Language) based web document by XSLT. And it also generates XML business message validating for e-Business DTD by user Inputs.

This paper presents details of the design and implementation of a report generator, Moonlight, which supports to design the report form from DB or data sources and print it to the printer. Also this paper defines the detailed model of the report system, the architecture and behavior of MoonLight, and the components of the report form, and also shows algorithms to make the report template and print the report bound to the data source. Moonlight takes advantage of XML language for the report template form. And also it is implemented by Jana language to take the advantage of platform independency. This paper also shows the results of run-time performance of Moonlight which is measured with the time to construct page objects of a report and the time to render the page objects to the print images, respectively.

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.

Though XML is widely used, it is still hard for end users to write XML documents. A lot of XML documents are data-centric documents which have formal data format. Even novices can easily write the data-centric XML documents if they use form-based GUIs. In this paper, we introduce a new method for generating form-based XML editor for data-centric XML documents automatically and an XML editor generator called XED. The DTD consists of sequence, choice, and repetition, and this structure can be represented with Document Decomposition Graph(DDG). XED allows users to generate an XML editor by applying the presentation rules to DDG. It also permits users to modify generated editor through changing editor`s GUI properties with direct manipulation.
