현재 복합 도금은 많은 학문적 연구자에 의해 이론적 배정에 대해 정립되었으며 다양한 실험 조건에 따른 영향을 관찰한 논문들이 많이 있다. 하지만 이러한 노력에도 불구하고 체계적인 실험 조건에 따른 영향을 관찰하고 이론적 배경에 관한 모델들에 대해 정리된 내용들은 부족하였다. 이에 저자는 복합 도금에 관한 이론적 배경, 다양한 실험 존건에 따른 결과 그리고 실제 그리고 실제 실험 조건에 따른 현상을 정리하여 복합 도금의 학문적인 정리를 하고자 하였다.

본 논문에서는 지하에 매설된 통신 관로의 상태를 조사하기 위해, 레이저 투영 영상을 이용한 관로의 최소 직경을 산출하는 새로운 방법을 제안한다. 투영 영역을 정확히 분할하기 위하여 새로운 색차 모델과 다중 임계치를 적용하였다. 관로의 투영 단면은 레이저가 투영된 곡선의 형상에 나타나므로 곡선의 최소 직경을 계산하여 관로가 찌그러져 있거나 이물질이 존재하는 것을 구분할 수 있다. 제안하는 기법은 100mm의 정상 관로에서 평균 1.83mm의 오류를 나타내어 관로의 상태를 조사하는 기법으로 사용이 가능하다.

A theoretical model was proposed to predict the rate of particles impinging on the negatively biased substrate and the total kinetic energy per unit time. The model takes into an account of kinetic theory based on Maxwell statistics and elementary plasma theory, incorporated with Hertz-Knudsen's evaporation theory. It is found that as the bias potential increases the ion flux and kinetic energy increases to a value above which the effect of potential is insignificant.

Many important physical properties of natural or man-made aerosol particles such as light scattering, electrostatics charges, and toxicity, as well as their behavior involving physical processes like diffusion and thermophoresis depend strongly on their size distribution. Important aerosol behavior mechanisms affecting the size distribution of aerosol particles include condensation, deposition, and coagulation. (omitted)

This paper describes an evaluation of reinforcement tension in RC beams using the variable truss models. The models were examined with the beam test results by Kim, Kim and White. Consequently, a fixed inclination $\theta$ at the support un-explains global state of internal force flow in cracked reinforced concrete beams subjected to shear and bending. Accordingly, we must introduce the arch factor for development of consistent model in reinforced concrete beams subjected to shear and bending

RAM(Reliability, Availability, Maintainability) characteristics of weapon system is a part of Required Operational Capability, must be reasonable and achievable. In this study, we studied the criteria, important factors to establish RAM requirement and reviewed the current process. Then we propose the new process and method to establish the reasonable and achievable RAM requirement by BCS(Baseline Comparison System) model.

The purpose of this study is to suggest analysis model of RCB construction in nuclear power plant. For the objective, This study drew the risk factors of RCB construction from existing literature. The results of the study proposed analysis model made hierarchy in rebar, form, and concrete work. These will be baseline data for risk management in construction project of nuclear power plant.
