한의학적 진단 이론은 우수성을 보유하고 있음에도 불구하고 계량화, 정량화되어 시각적으로 표현해 주는 결과를 보이지 못해 서양의학에 비해 뒤떨어져 있는 실정이다. 따라서 본 논문에서는 한의학의 망진을 의료 시스템화 하기 위한 한 단계로서 찰색의 기본이 되는 피부색의 분석을 행하였다. 이를 위해 각 개인의 피부색 차이를 수렴하고 이에 대한 분석을 시행함으로 피부색에 대한 공학적 분석을 시도하였다. 본 논문에서는 객관적으로 피부가 검은 사람과 흰 사람을 비교, 분석하였으며 또한 일반인들을 대상으로 피부색 분석을 실행하여 피부색에 대한 개념을 정립하고자 한다. 마지막으로 이에 대한 평균값을 구하며 망진 시스템의 주된 대상이 되는 황인종의 피부색에 대한 연구를 행하고자 한다.

The aim of the thesis is to examine why children comics books are not popular in Korea and how to analyze the causes for solution. The way for solving the problems is to make academic events and make a public opinion about children comic books. In the subject, we introduce children comic books and define them, actually when we do that, we have realized that most people misunderstand children comic books so we should change them to take the adventagement. Next, Through academic events, we have enumerated the variety of opinions. Mainly, we have concluded about the improvement of the misunderstanding comics. There are some prejudices of children comics. First, we are in a need of comics, that are very creative and sensitive. They are very important to develop children's character. Second, Korean people think, The most important part of the literature is a letter more than pictures, That causes not to develop motion pictures, cartoons and even plays. Third also, creative children comics don't effect not only studying but also children violence. Fourth, We can't ignore the prejudice of the comic books from parents, The main reason why comic books aren't popular in korea is the University entrance examination system that makes student like a studying meachine. The conculusion of this study is that We will educate Korean people to understand comic books and redefine them for development the comic books.

Lately construction industry tends to prefer remodeling of existing buildings rather than new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. And also, remodeling of building costs less and creates less wastes compared to reconstruction and so it is more profitable in financial and environmental view. However remodeling is process of creating new environment with existing building. Therefor remodeling must follow the procedure realizing problem and fix the problem based on through investigation on existing building and users requirement must be faithfully reflected. Specially in case of apartment houses, since vagueness on ownership and management authority on common parts exists. Hereupon, in this study we are to present the procedure of analyzing apartment house remodeling method through user requirement by approaching to several considerable factors in user request side.

The main objective is to predict the future degradation and maintenance budget for a suspension bridge system. Bayesian inference is applied to find the posterior probability density function of the source parameters (damage indices and serviceability), given ten years of maintenance data. The posterior distribution of the parameters is sampled using a Markov chain Monte Carlo method. The simulated risk prediction for decreased serviceability conditions are posterior distributions based on prior distribution and likelihood of data updated from annual maintenance tasks. Compared with conventional linear prediction model, the proposed quadratic model provides highly improved convergence and closeness to measured data in terms of serviceability, risky factors, and maintenance budget for bridge components, which allows forecasting a future performance and financial management of complex infrastructures based on the proposed quadratic stochastic regression model.

The objective of this study is development of the optimum design program to minimize the cost for PSC box girder bridge using the full staging method to indicate the necessity for the optimum design applied many types of bridges. It also considered the proper span length to girder depth ratio and the cell number along the width of bridge. This program used SUMT procedure and Kavlie's extended penalty function to allow infeasible design points in the process. Powell's direct method was used in searching design points and Gradient Approximate Method was used to reduce design hours. This study showed the convergence in design parameter and correlation of totally optimized cost according to cell numbers, span lengths, and lane numbers.

In the recent construction industry, Carbon Fiber Reinforced Polymers(CFRPs) have been highly considered as innovative strengthening materials for civil structures due to their superior material properties. This paper is to offer design data and strengthening efficiency of reinforced concrete beams strengthened with CFRP Plate. Static tests were carried out to evaluate failure modes and strengthening capacity. Displacements and strains of steel and CFRP plates were obtained and analyzed through a series of fatigue tests. Also, Those evaluated the energy dissipation. Results of the tests showed increase in strengthening ratios caused debonding failure at the end of beams. For the beams wrapped with CFRP sheets around the end of the plates, debonding failure mode that was induced from flexural cracks was indicated. Through the fatigue tests, it was observed that displacements, strains of steel and CFRP plates converged into certain values. It is also proved that the beams strengthened with CFRP plates are able to resist fatigue loading under serviceability.

Recently, in field of bridge construction, modular technology has been studied to reduce construction period, traffic impact and environmental impact. This study is a part of research related to the modular bridges. The aim of the study is to analyze the structural behavior and evaluate a serviceability for transverse connection of modular slab bridge. A total of four specimens were fabricated. including a control beam for finding the maximum load by static test. And one control beam and two segmental beams were fabricated for cyclic loading test. As the test result, the beams that were introduced 100% of the design prestressing force showed a smaller maximum deflection, residual deflection and crack width than the control beam. The beam for serviceability evaluation was satisfied with structural serviceability limits of the deflection and crack.
