화풍을 효과적이고 객관적으로 기술하는 한 방법으로 팔레트 추출에 대한 수학적 모델을 제시한다. 이 모델에서는 팔레트를 허용 오차 범위 내에서 회화 작품의 영상을 표현할 수 있는 주요 색상의 집합으로 정의하고 색상 그룹핑과 주요 색상 추출의 두 단계를 거처 팔레트 색상을 추출한다. 색상 그룹핑은 주어진 회화에 대해 적응적으로 색의 분해능을 조절하여 각 회화 작품을 이루는 기초 색상을 추출하며 다음 주요 색상 추출 단계에서 이것과 이것이 차지하는 영역에 대한 정보를 바탕으로 K-Means 클러스터링 알고리즘을 적용하여 팔레트를 얻는다. 실험을 통해 유명 화가의 작품을 대상으로 RGB와 CIE LAB 색상 모델을 사용하여 추출한 팔레트를 3차원 색 공간에 표시하였다. 팔레트 색상의 거리를 사용한 화가 분류 실험과 실사 영상의 색채 변환 실험 통해 이 방법이 화풍 분석과 그래픽 분야에 적용될 수 있음을 확인하였다.

In the present work, vibration analysis of high speed rotary bell cup model for paint atomizer application is carried out through numerical simulation. At first, eight bell cup models, considering four different cup shapes and two different cup diameters, are proposed and corresponding dynamic characteristics are investigated. To evaluate the operating stability, critical speed analysis is conducted using Campbell diagram and separation margin between operating speed and critical speed is identified. Unbalance vibration responses are also studied according to operating speed and balancing quality grade of G. Finally, the stability and adequacy of the proposed bell cup models are discussed for field application.

This study aims to develop high durability graphene / epoxy paint for durability improvement of construction structure. For the development of graphene / epoxy coatings, first, graphene must remain stable in the polymer. Second, the integrity of graphene and polymer should be ensured. Accordingly, in order to obtain dispersibility, surface modification of graphene nanoplate(GnP) with CH and COOH functional groups and its dispersibility in organic solvents were investigated. Also, Fourier Transform Infrared Spectroscopy(FT-IR) analysis and Atomic Force Microscope(AFM) analysis were performed to confirm whether the functional groups were synthesized by surface modification. As a result, FT-IR and AFM analysis did not confirm the surface modification, but GnP was found to be stable when dispersed in an organic solvent.

A green fluorescent protein-based Pseudomonas putida reporter was successfully constructed and shown to be capable of detecting oxidative stress. In this whole-cell reporter, the promoter of the paraquat-inducible ferredoxin-$NADP^+$ reductase (fpr) was fused to a promoterless gfp gene on a broad-host-range promoter probe vector. Pseudomonas putida KT2440 harboring this reporter plasmid exhibited an increased level of gfp expression in the presence of redox-cycling agents (paraquat and menadione), hydrogen peroxide, and potential environmental pollutant chemicals such as toluene, paint thinner, gasoline, and diesel. Induction of fpr in the presence of these chemicals was confirmed using Northern blot analysis.

The questionnaire inquiry used of Analytic Hierarchy Process was carried out for both designers and common housewives to characterize the main demanding stratums for interior finishing goods in October, 2004. The results were summarized as follows; The interior finishing materials regarded as important in residential space were by the order of Wood Floor for Ondol, Wall Paper, Emulsion Paint; Environmentally-Friendly Wall Paper appeared its value of 1.56 times than Ordinary Wall Paper, in the same case of Emulsion Paint is at 1.63 times, Wood Floor at 2.12 times, respectively. Besides, as the result of correlation and regression analysis, they preferred to environmentally-friendly property by the nearer women, the nearer larger incomes, the nearer highly educated, and the nearer non-experts (housewives).

건축물의 화재발생 시 건축물 붕괴방지 및 인명의 피난시간 확보를 위하여 내화구조(내화피복재)를 시공하도록 하고 있으나 실제 규모와 가까운 내화시험의 특성으로 건축물 시공현장에서 내화구조(내화피복재)의 품질을 확인할 수 있는 현장품질방법이 부재하다. 따라서 근-적외선분광분석을 통하여 현장에서 적용할 수 있는 일치성 분석기법 연구를 통해 정확하고 간편한 과학적 내화구조현장관리 시험방법을 제시하고자 함.

본 연구에서는 차열소재로 사용되는 mica의 소수성을 향상시키기 위해 실란커플링제인 octyltriethoxysilane (OTES)으로 개질하였다. 개질한 mica의 FT-IR spectrometer, 젖음성 및 수 접촉각 평가를 한 결과 OTES가 mica 표면에 화학적으로 잘 결합되어 있고, 소수성도 크게 향상된 것으로 평가된다. mica와 OTES/mica를 이용하여 제조한 차열페인트의 반사율은 각각 73.9% (mica) 및 86.4% (OTES/mica)로 OTES/mica의 경우가 12.5% 증가하였다. 차열성능평가 결과는 OTES로 개질한 페인트가 개질 전과 비교하여 약 $7.2^{\circ}C$ 감소되어, 소수성 실란커플링제로 개질된 mica가 페인트의 차열성능을 향상시키는데 효과가 있음을 확인하였다.

It is highly recognized that there is need for protection against indoor air pollution, as we realize environmental pollution is growing, For example, in an indoor environment, a person spends more than 80 percent of their time inside the building. Thus, concern about indoor decoration materials is growing, since they cause pollution in the rooms of an apartment, as well as in offices. As the indoor decoration materials become more diverse and lusurious, so the effect of VOCs(Volatile Organic Compounds) and HCHO(Formaldehy) is growing. The indoor decoration materials cause the Sick Building Syndrome, such as headaches, dizziness, or lack of concentraion, and they in turn cause serious deterioration in people's health. In this study, I probed the status of the indoor air pollution and carried on an investigation and analysis about the prevention technique. In doing so, I performed experimental tests and an assessment of the indoor decoration materials of an apartment. I also examined elements of the emitted and the emission. Finally, I examined the character of emissions, by changing environmental conditions, such as the temperature, humidity, and ventilation. With respect to VOCs tests, I applied the method of solid state adsorption using the adsorptive tube, based on the measurement of the American EPA TO-17, ASTM 5116-97, and the measurement of the Japanese Wall Decoration Industrial Association. The tested sample was analyzed by High Performance Liquid Chromatography, after going through the process of dissolvent extraction. As subjects of the test, Paint were selected. The process of this test is as follows; first, I figured out the character of the emission, by measuring the emitted concentration of VOCs and HOHC from the indoor decoration materials of an apartment. Second, I made a small-scale chamber and the test was processed in the chamber in order to suggest an environment-friendly prediction modlel development.

Under the doctrine of separability, if the party did not specifically challenge the validity of the arbitration clause, then it is presumed valid, and arbitrators would still have authority to adjudicate disputes within the scope of the arbitration clause. Further, the Primerica and Spahr decisions address whether a court or an arbitrator should adjudicate a claim that a contract containing an arbitration clause is void ab initio due to mental incapacity. If the arbitration agreement is separable, as was found in Primerica, then the "making" of the agreement is not at issue when the challenge is directed at the entire contract and arbitrators may exercise authority. If an arbitration provision is not separable from the underlying contract, as in Spahr, a defense of mental incapacity necessarily goes against both the entire contract and the arbitration agreement, so the "making" of the agreement to arbitrate is at issue, and the claim is for courts to decide. Although no bright line rule can be established to deal with challenges of lack of mental capacity to an arbitration agreement, the rule in Prima Paint should not be extended to this defense. Extending the rule in Prima Paint would force an individual with a mental incapacity to elect between challenging the entire contract and challenging arbitration. Accordingly, there should be a special set of rules outside of the context of Prima Paint to address the situation of status-based defenses, specifically mental capacity defenses, to contracts containing arbitration provisions.

현대 사회에서 색채가 인간에게 미치는 영향은 정신적 심리적 측면에서 중요한 요소로 나타나고 있다. 색채는 시지각적으로 인간의 마음에 일어나는 감정과 정서를 연출하여 메마른 감성을 치유하며, 환경은 표현된 색채에 따라 삶의 가치를 높여 주는 역할을 한다. 본 연구에서는 금속의 단조로운 색채표현을 해소하기 위한 측면으로 금속 장신구에 옻칠과 포슬린150물감을 사용하여 표현하는 방법을 응용시켜 다양한 색채변화를 나타내었다. 옻칠과 포슬린150물감의 금속시편을 제작하고 비교 분석하여 장 단점의 결과로 도출하였다. 장점은 이를 접목하는 방법은 금속 색채표현의 일반적인 방법에 비해 색채효과를 다양하게 표현할 수 있었고, 표면 코팅 역할을 하므로 기물의 변색을 방지하여 가변적 문제점을 보완해 줄 수 있었다. 단점은 옻칠은 체질에 따른 옻오름 현상이 나타나고, 포슬린150페인팅은 화학성분으로 식기류에 사용하면 건강에 해로울 수 있다. 이를 참고하여 작품에 적용하여 예술성과 실용성 구현에 기여하고자 한다.
