Neu, V,Schulze, C,Faustini, M,Lee, J,Makarov, D,Suess, D,Kim, S-K,Grosso, D,Schultz, L,Albrecht, M IOP Pub 2013 Nanotechnology Vol.24 No.14
<P>Magnetization reversal processes in Co/Pt multilayers prepared on nanoperforated templates are probed by magnetization relaxation measurements. The signature of pinning controlled domain wall movement as expected for percolated media is identified. This contrasts with the nucleation-type reversal mechanism of a Co/Pt reference film prepared on a smooth substrate. A zero field energy barrier of 93<I>k</I><SUB>B</SUB><I>T</I> is determined by fluctuation field measurements and is elucidated by micromagnetic calculations using the nudged elastic band method. This value is sufficiently large to qualify the material as a promising percolated medium.</P>

권은녀(Eun Neu, Kweon) 신라대학교 여성문제연구소 2013 젠더와 사회 Vol.24 No.-
펀의 각색된 자서전인 이 소설의 여주인공 루쓰(Ruth)는, “가정의 영역을 다스리고 가정에서 힘을 얻은 것처럼 비추어지는” 19세기 여성 소설의 일반적인 여주인공들이 행사하는 능력의 범위를 넘어선다. 그녀는 여성으로서의 정체성을 찾는 수단으로 삶 속의 노동을 선택하고 일을 통해 자신의 영향력을 집 밖 세계로까지 펼친다. 홀로 서는 비즈니스 우먼으로 거듭나는 루쓰의 모습을 통해, 소설의 전반부에서 높이 평가되고 있는 사적 영역으로서의 가정에 대한 감상적인 가치가 남성중심 사회에 의해 부풀려져 있음이 폭로 된다고 볼 수 있다. 한 가지 주목할 것은, 『루쓰 홀』은 자본주의에서 성공하는 여성의 이야기를 소개하지만 펀은 루쓰가 잔인한 자본주의 세계 안에서 모성과 일의 조화가 일어나는 공간을 만들었다고 믿는다. 루쓰가 수행해 가는 공적인 영역에서의 일은 전통적으로 규정된 가정영역에서의 여성의 역할과 분리되어있거나 가정영역에서의 노동의 의미를 전복시키고 있지만, 이 노동은 가족적 연결을 배제하지는 않는 것이다. 공적영역에서의 일의 수행에서, 모성은 여성이 남성에 비해 열등하지 않는 새로운 공간을 만들어 내는 역할을 한다. 루쓰는 남성지배 사회가 규정한 진정한 여성의 영역에서 다락방으로, 다시 자본이 지배하는 공적사회로 이동하며 여성에게 금지된 그곳에서의 일을 통해 한 인간으로서의 고유한 존재성을 깨달아간다. The purpose of this paper is to reveal how specious the ideology of separate spheres can be. To expose the flaws of this ideology, Fern uses satire and sentimental rhetoric to undermine traditional values such as “True Womanhood,” which according to Barbara Welter, are composed of four virtues, namely “purity,” “piety,” “submissiveness,” and “domesticity,”, and the prevalent concept of men’s sphere in the public space and woman’s sphere in the private home, and to advance the feminist agenda of the necessity of work for women. Therefore, this thesis attempts to show how Ruth Hall points out the problematics of the binary concept of the separate spheres and insists on the importance of work for a woman to be able to maintain her identity as a human being and to raise her children in mid-nineteenth century America. Financial assistance neither from her father nor from her fatherin-law shows that the white middle-class ideology of separate spheres can not protect a woman like Ruth, who is dropped from middle-class status and plunged into that of the lower classes in a day. This situation in itself deconstructs the ideology of separate spheres which commands that women stay in the private sphere of the home and only do the domestic work. In spite of interruptions from her relatives, her success as a writer in a competitive capitalist society proves the falsity of the ideology of separate spheres which very strictly divides the public sphere and the private sphere. Ruth discovers herself as a human being and gains a sense of selfidentity as a woman. The sympathy her readers show to her is expressed in the readers’ letters written to her, and it encourages her to do all of these. She transcends the dichotomy of the separate spheres and dreams of a new home in which a new order replaces the home where the traditional ideology of separate spheres still governs.

일 정신과 단일전문병원 입원환자의 흡연에 대한 지식과 태도에 관한 연구
고귀녀 외 국립서울병원 정신보건교육·연구센터 2009 정신건강정책포럼 Vol.3 No.1
Purpose : Smoking has bad effects on not only ordinary smokers but non smokers around themselves for social and economical problems. Smoker is decreasing by anti smoking campaign and doctor's counsel. But psychotic smoker has a few chance to get them not to smoke, comparing with ordinary smokers, furthermore they are allowed to smoke in psychotic hospital. A research reported that the rate of psychotic smokers are 52~88%, comparing with ordinary smoker are 30~33%. Methods : We surveyed the rate of smokers for the psychotic smokers in psychotic hospital, Seoul, South Korea , Feb. 25 ~ Feb. 29, 2008. This paper analyzed about their non smoking will and information of danger for smoking, through these survey. Results : The result is that the ratio of smoker in psychotic hospital is 46.7%, among them, man smoker is 57.7% and woman smoker is 64.3%. Then 35.9% of them smoke 10~20 cigarettes per a day, over 20 cigarettes is 27.1%, 5~10 cigarettes is 22.2%, under 5 cigarettes is 11%. Conclusion : This paper suggest that it is need to develop effective and proper anti smoking education for smoker in psychotic hospital, on basis of this research.

An anisotropic tertiary creep damage constitutive model for anisotropic materials
Stewart, Calvin M.,Gordon, Ali P.,Ma, Young Wha,Neu, Richard W. Elsevier 2011 The International journal of pressure vessels and Vol.88 No.8
<P><B>Abstract</B></P><P>When an anisotropic material is subject to creep conditions and a complex state of stress, an anisotropic creep damage behavior is observed. Previous research has focused on the anisotropic creep damage behavior of isotropic materials but few constitutive models have been developed for anisotropic creeping solids. This paper describes the development of a new anisotropic tertiary creep damage constitutive model for anisotropic materials. An advanced tensorial damage formulation is implemented which includes both material orientation relative to loading and the degree of creep damage anisotropy in the model. A variation of the Norton-power law for secondary creep is implemented which includes the Hill’s anisotropic analogy. Experiments are conducted on the directionally-solidified bucket material DS GTD-111. The constitutive model is implemented in a user programmable feature (UPF) in ANSYS FEA software. The ability of the constitutive model to regress to the Kachanov-Rabotnov isotropic tertiary creep damage model is demonstrated through comparison with uniaxial experiments. A parametric study of both material orientation and stress rotation are conducted. Results indicate that creep deformation is modeled accurately; however an improved damage evolution law may be necessary.</P> <P><B>Highlights</B></P><P>► The deformation of anisotropic creeping solid is directionally dependent. ► Few constitutive models have been developed to deal with anisotropic behavior. ► A transversely-isotropic nickel base superalloy, DS GTD-111, is studied. ► A vector constitutive model based on the Kachanov-Rabotnov formulation is developed. ► The new model accurately models deformation at various orientations.</P>
