Many fashion designers have created new works through the methods of changing the past style by introducing the past art-style to dress and ornaments since 1980's, for the inner beauty and outer beauty which have an art-style could offer not only an inducement to design as an expressive means for the dress and ornaments, but motive to social receptivity as fashion phenomenon. In such views, this study was carried out to examine the process how an outer form has been changed by an introduction of art-style that is an expressive means of dress and ornaments for the fashion, and to find the method how its inner beauty has been assimilated and affected in the social receptive step, as investigating an effect of art style to fashion-style. the purposes of this study are as follow; First, to analyze an inner meaning and outer form that the art-style have influenced on the fashion-style from 1985-1992. Second, to analyze an effect of art-style to outer from of fashion-style with an effect of inner beauty to fashion phenomenon. Third, to explain the fashion phenomenon as revealing an evolutionary relation between art fashion and current thought of times that accepted and expressed art-style with the constituent elements of dress and ornaments such as line, color, and material. This study examined characteristics of works in pret-a-porter Collection, Paris where in the center of creating fashion by art-style that have influenced on the fashion-style, and then analyzed the form's changes which have been adjusted to fashion style by the constituent element(color, material, line, trimming, detail, and silhouette) and manner of dress. Also, this study analyzed how the art fashion that can bbe a motive power for the changes of fashion-style in times will have influence on or be expressed to the given form as investigating the fashion environments such as society, politics, economy, culture psychology and technique which the art-style is socially accepted and expressed through the study on literatures. The results are as follows: 1. Art-style that have influenced on the fashion-style from 1985 to 1992 was the constructivism and post-modernism. 2. What the constructivism could be accepted to society was due to resistance on the decorative. Accordingly, unpolished culture became to expressed to constructivism who has sought the stronger vector from the simple thing. 3. The constructivism that was introduced to fashion tried to fulfill new body-conscious spatial construction on human body in pursuit of formalization of construction, function, and form as well as to seek dynamic rhythm in the unsymmertical order. 4. The post-modernism that used the reconstructed past style as a motif of new idea for style's rapid changes was socially accepted, for it imparted the spiritual abundance and visual joy in re-interpreting special culture and tradition of each area by cosmopolistanism and localism of post-ideology, especially due to the new\wave spirit of new generation who sought new things in the process of destroying preconceived sense of value and existing order. 5. The post-modernism expressed has expressed sex, attractiveness, eroticism created new style of resisting to the elegant and polished beauty due to an effect of pop-art as formal change, brought the begger style and japanese-look into vogue that ignores the basic principle and form of dress and ornament by Punk-style. Also, not only it created the fashion-style of closed up it without to deny characteristics of men and women by Androgynous-fashion, but it expressed the Folkore and Ethnik fashion which gave the spiritual abundance and visual joy to the moderns as introducing culture and dress of minority race into the fashion. the Elology-fashion made possible the loose look that expressed the floral design by fashion which selected the nature destroyed up-to-date as motif, and Anti-fashion made possible Kitsch, Hoodrum, and Grunge-fashion as antiartistic, anti-moral, and anti-rational style of Dadaism. The several cultural fashions have been expressed in open society with the mix and match look as pluralism. The Fin de Siecle factors such as avant-grade expression, Decadance and Det-tester that rised above the daily life were also expressed to the fashion.

원전의 구조적 건전성에 문제가 될 수 있는, 오스테나이트계 합금의 환경조장균열(EAC)에 대한 거동을 실험적인 결과와 문헌 조사를 통해 분석하였다. 일차측 환경에서 주기적인 반복하중을 받을 때에는 기계적인 피로균열에 더해 수소 유기균열이나 동적변형시효 등으로 인한 가속화 메커니즘을 통해 피로수명 감소가 나타났다. 따라서 EAF에 대한 저항성은 전반적인 부식저항이 우수한 니켈기합금이 스텡인리상강보다 크게 나타났다. 그러나 일정한 하중을 받을 때에는 내부산화에 의해 국부적인 취약부인 입계로의 빠른 균열의 생성과 진전이 나타나 일차수 응력부식균열(PWSCC)이라는 형태로 발생한다고 여겨진다. 이때는 니켈-크롬의 비율이 내부산화 저항성에영향을 미쳐, 비율이 낮은 스테인리스강은 높은 저항성을 가지고, 비율이 높은 니켈기합금은 낮은 저 항성을 가진다. 그러나 아직 이러한 균열 메커니즘에 대한 명확한 이해가 부족하므로, 명확히 규명하기 위해 서는 추가적인 연구가 필요하다. Austenitic stainless steels and Ni-base alloys are widely used as structural materials for major components and piping system in pressurized water reactors (PWRs). These austenitic alloys are known to be susceptible to environmental assisted cracking (EAC). Such as environmentally-assisted fatigue (EAF) and primary water stress corrosion cracking (PWSCC) during long-term exposure to PWR primary water environment. In this paper, the current understanding on the phenomena and mechanisms of these EAC are briefly introduced using experimental results and literature review. The mechanisms for EAF and PWSCC for austenitic stainless steels and Ni-base alloys are discussed. Currently, austenitic stainless steels are known to be more susceptible to EAF, while less susceptible to PWSCC than Ni-base alloys. The possible explanations to such behaviors are proposed and discussed in view of the role of hydrogen and internal oxidation.

후쿠시마 원전 사고 이후 사고시 핵연료의 위험성을 저감하기 위하여 전 세계적으로 사고저항성 핵연료(accident tolerant fuel, ATF)의 개발이 진행중이며, 특히 단기 상용화를 위하여 기존 지르코늄 합금 피복관에 산화저항성이 우수한 물질을 표면에 코팅하는 형태의 표면개질 기술의 개발 및 고도화가 진행중이다. 국내에서는 KAERI 가 아크 이온 플레이팅법(arc ion plating)을 이용하여 Cr/CrAl 코팅을 적용하였다 [1]. 그러나 코팅의 박리가 발생하면, ATF 피복관의 장점(산화, 기계적 특성 등)을 잃게 되며 다양한 형태의 국부적인 손상이 발생할 수 있다. 이러한 이유로 코팅 결착특성은 코팅된 ATF 핵연료 피복관의 중요 특성임에도 불구하고, 측정 기술의 한계로 관련 연구가 제한적이었다 [2]. 본 연구에서는 얇은 코팅층을 절삭 및 박리하면서 결착특성을 측정할 수 있는 SAICAS(Surface And Interfacial Cutting Analysis System)를 도입하여, 코팅 ATF 피복관의 결착특성을 정량적으로 측정하였다. SAICAS는 기존의 스크래치시험과 박리시험과의 비교를 통해 신뢰성이 검증된 바 있다 [3,4]. SAICAS DN-EX에 0.3mm 폭의 미소 다이아몬드 칼날을 장착하여 0.5μm/s, 5μm/s의 수직/수평방향 속도로 Cr 코팅 ATF 피복관의 코팅층을 절삭하였다. 이 때 코팅과 모재의 경계면에서 코팅을 박리시킬 때 걸리는 수평방향의 힘을 측정하고 이를 코팅의 결착력으로 환산하였다. 이를 통해 정량적인 박리강도를 도출하였으며, SAICAS가 ATF 피복관에 적용된 코팅의 결착특성 분석에 용이하게 적용될 수 있음을 확인하였다. To enhance nuclear safety during accident condition, the accident tolerant fuel (ATF) cladding has been in development by nuclear industry since the Fukushima accident. Especially, surface-modified Zr cladding concept by oxidation resistant coating is most promising because of the commercialization in near-term. Korea Atomic Energy Research Institute (KAERI) applied the Cr/CrAl coating using arc ion plating method to existing Zr-based cladding [1]. However, the benefits of ATF cladding (e.g. oxidation, mechanical properties) would lose and localized failure occurs, once coating layer delaminates. In this regards, coating adhesion properties are critical issues for coated ATF, but related research has not been performed extensively due to the limitation of measurement technology [2]. In this study, surface and interfacial cutting analysis system (SAICAS, Daipla Wintes Co., Ltd, Japan), which can measure the adhesion properties while cutting and peeling a coating layer, has been introduced and applied for analyzing quantitatively the adhesion properties of coating layer on ATF cladding. SAICAS verified the by comparison with scratch test and peel test [3,4]. The adhesion properties of Cr-coated ATF cladding were measured using SAICAS DN-EX with micro-diamond blade (width=0.3mm) at vertical/horizontal cutting rates of 0.5μm/s and 5μm/s, respectively. The measured horizontal force during peeling stage converted to adhesion force and peel strength at matrix/coating interface. From the analysis, the coating adhesion properties of coated ATF cladding was quantitatively evaluated using SAICAS.

As an accident tolerant fuel (ATF) concept, oxide dispersion strengthened Zircaloy-4 (ODS Zry-4) claddinghas been developed to enhance the mechanical properties of cladding using laser processing technology. In this study, a simulation technique was established to investigate the mechanical properties and effectsof Y2O3 particles for the ODS Zry-4. A 3D representative volume element (RVE) model was developedconsidering the parameters of the size, shape, distribution and volume fraction (VF) of the Y2O3 particles. From the 3D RVE model, the Young's modulus, coefficient of thermal expansion (CTE) and creep strainrate of the ODS Zry-4 were effectively calculated. It was observed that the VF of Y2O3 particles had asignificant effect on the aforementioned mechanical properties. In addition, the predicted properties ofODS Zry-4 were applied to a simulation model to investigate cladding deformation under a transientcondition. The ODS Zry-4 cladding showed better performance, such as a delay in large deformationcompared to Zry-4 cladding, which was also found experimentally. Accordingly, it is expected that thesimulation approach developed here can be efficiently employed to predict more properties and toprovide useful information with which to improve ODS Zry-4.

Anti-fashion that is an avant-garde expression under the spirit of dadaism has affected the high fashion as appearing to teddy boys, mods, hippies, skin heads, and punk which are the deviant behaviors of subcultural group formed by urbanization. High fashion showed forms to shoulder, to engirdle, and to slip on in accordance with a variety and unconstructive silhouette, in disregard of an existing form of clothes and use of new mate-rials such as paper, vinyl, plastic, and metal. The reason why such and anti-fashion style has come into vogue in these days is what anti-fashion could most express a characteristic of mass society. In such a viewpoint, this study was carried out to seek after a formation and change of fashion in mass culture to adopt a structure of mass society. An individual has become to accept a culture to stimulate a primitive instinct of human begins who have been mentally suppressed due to individual dehumanization and standardization in mass society formed through the indusrialization, urbanization, and bureaucratization. In such a society, fashion is expressed not only to anti-fashion with self-assertion and strong individuality which seeks to be different from the others, but to mix look of expression unfitted for a coordinate concept, because the more decisions should be reached at once under the plurality, multi-relationality, and homelessness. Anti-fashion style is expressed to surface and sensual fancy beauty as an over-dressing of over-design under the phenomenon of goal displacement. Also, a primitive thing which freed from any given bondage of clothes is expressed in fashion, because what the human has been isolated from the nature appears its own heart and liberty that hope to be back to the nature.

장창희,장훈,홍종대,조현철,김태순,이재곤 한국원자력학회 2013 Nuclear Engineering and Technology Vol.45 No.7

Environmental fatigue of the metallic components in light water reactors has been the subject of extensive research andregulatory interest in Korea and abroad. Especially, it was one of the key domestic issues for the license renewal of operatingreactors and licensing of advanced reactors during the early 2000s. To deal with the environmental fatigue issue domestically,a systematic test program has been initiated and is still underway. The materials tested were SA508 Gr.1a low alloy steels,316LN stainless steels, cast stainless steels, and an Alloy 690 and 52M weld. Through tests and subsequent analysis, themechanisms of reduced low cycle fatigue life have been investigated for those alloys. In addition, the effects of temperature,dissolved oxygen level, and dissolved hydrogen level on low cycle fatigue behaviors have been investigated. In this paper, thetest results and key analysis results are briefly summarized. Finally, an on-going test program for hot-bending of 347 stainlesssteel is introduced.

Low-cycle fatigue (LCF) tests were performed for Alloy 690 and 316 SS in a simulated pressurized waterreactor (PWR) environment. Alloy 690 showed about twice longer LCF life than 316 SS at the test conditionof 0.4% amplitude at strain rate of 0.004%/s. Observation of the oxide layers formed on the fatiguecrack surface showed that Cr and Ni rich oxide was formed for Alloy 690, while Fe and Cr rich oxide for316 SS as an inner layer. Electrochemical analysis revealed that the oxide layers formed on the LCF cracksurface of Alloy 690 had higher impedance and less defect density than those of 316 SS, which resulted inlonger LCF life of Alloy 690 than 316 SS in a simulated PWR environment
