자기보고 능력이 부족하다고 알려진 학령전기 아동의 임상 평가는 외부관찰자의 보고에 의존하는 점이 많고 아동 자신의 내적인 경험, 생각, 감정에 대한 직접적인 평가가 어렵다. 본 연구에서는 놀이 상황에서 학령전기 아동의 내적 마음의 표상을 알아보기 위해 개발된 MacArthur Story-Stem Battery(MSSB)를 사용하여 정상 아동의 내적 마음의 표상의 발달에 대한 연구를 시행하여 학령전기 아동의 임상 평가에 도움을 주고자 하였다. 본 연구는 만 3세부터 7세까지의 정상 아동 55명(남아 32명, 여아 23명)에서 MSSB, 언어평가(Peabody Picture Vocabulary Test-Revised), 지능평가를 시행하고 비디오로 녹화하여 분석하였으며 결과는 다음과 같다. 1) 정서적인 갈등 상황을 설정한 놀이에서 아동들은 비전형적 부정적 반응, 보상/죄의식, 처벌, 개인적 상해 등의 부정적인 정신적 표상이 흔히 표현되었다. 2) 부모에 대한 정신적 표상은 긍정적 표상, 훈육적 표상, 부정적 표상의 순으로 표현되었다. 3) MSSB 내용 주제요인 분석 결과, 비전형적 부정적 반응, 공격성, 개인적 상해, 배제로 묶이는 공격적 주제, 애정, 제휴, 죄의식/보상으로 묶이는 친사회적 주제, 처벌과 불복종으로 묶이는 반항적 주제 세 가지로 나타났다. 4) 부모에 대한 정신적 표상과 MSSB 내용 주제와의 상관관계를 살펴보면, 부모에 대한 긍정적 표상은 친사회적 주제와(r=0.40), 부정적 표상은 공격적 주제와(r=0.52) 그리고 훈육적 표상은 반항적 주제와(r=0.75) 유의미한 양의 상관관계를 보였다. 5) 부모에 대한 정신적 표상과 MSSB 정서 반응과의 상관관계를 살펴보면, 부모에 대한 긍정적 정신적 표상과 불안 사이에 유의미한 부적 상관관계(r=-0.43)를 보였다. 6) MSSB 내용 주제와 정서 반응사이의 상관관계를 살펴보면, 공격적 주제(r=0.28)와 반항적 주제(r=0.29)는 고통의 감정 반응과 유의미한 양적 상관관계를 보였고 친사회적 주제는 근심(r=-0.29), 불안(r=-0.43)과 유의미한 부적 상관관계를 보였다. 이상의 결과에 의하면 정서적인 갈등을 야기하는 놀이 상황에서 학령전기 아동들은 부정적인 정신적 표상을 흔히 보였으며 부모들은 자신들을 도와주는 긍정적인 표상으로 나타남을 알 수 있다. 또한 공격적 주제를 많이 보이는 아동들은 부정적인 정서 반응과 부모에 대해 부정적인 정신적 표상을 많이 나타냄을 알 수 있다.

Based on translation models, both Gaussian and non-Gaussian wind fields are generated using spectral representation method for investigating the influence of non-Gaussian characteristics and directivity effect of wind load on fatigue damage of wind turbine. Using the blade aerodynamic model and multi-body dynamics, dynamic responses are calculated. Using linear damage accumulation theory and linear crack propagation theory, crack initiation life and crack propagation life are discussed with consideration of the joint probability density distribution of the wind direction and mean wind speed in detail. The result shows that non-Gaussian characteristics of wind load have less influence on fatigue life of wind turbine in the area with smaller annual mean wind speeds. Whereas, the influence becomes significant with the increase of the annual mean wind speed. When the annual mean wind speeds are 7 m/s and 9 m/s at hub height of 90 m, the crack initiation lives under softening non-Gaussian wind decrease by 10% compared with Gaussian wind fields or at higher hub height. The study indicates that the consideration of the influence of softening non-Gaussian characteristics of wind inflows can significantly decrease the fatigue life, and, if neglected, it can result in non-conservative fatigue life estimates for the areas with higher annual mean wind speeds.

CPS는 다양한 임베디드 시스템들을 복합적으로 모델링 및 시뮬레이션 한다. 이때 다양한 종류의 모델이 사용되기 때문에 시뮬레이션에 사용되는 데이터들에 대한 체계적인 관리 위해 SEDRIS를 적용한다. SEDRIS는 특정 도메인 환경에서 개발된 환경데이터들을 재사용 및 상호운영 가능하기 때문에 비용과 시간을 절감할 수 있다. 기존 시뮬레이터와 SEDRIS를 연동 위해, 시뮬레이터의 지형 표현에 사용되는 높이맵을 SEDRIS의 레스터 데이터 표현방법으로 변환하여 입력만이 가능하다. 이 문제를 해결위해, 높이맵 표현을 위해 사용되는 RAW파일을 폴리곤 데이터로 변환하는 방법을 제안한다. 제안한 방법은 두 가지 이점을 제공한다. 첫 번째로 SEDRIS 내부에 환경데이터 표현이 가능해진다. 두 번째는 그림파일처럼 보이는 지형을 뷰어로 확인 가능하다. 즉, SEDRIS 비전문가도 지형 환경 데이터를 구축이 가능하다.

In the late nineteenth century, British colonial activities became aggressive and annexationist in the tropics, including the Southeast Asian Archipelago, which reflected the historical circumstances of both increasing resistance from the indigenous and severe competition among European powers. Interestingly, the change in English colonial policy toward an annexationist or imperialist vision adopted the motto of a civilizing mission, which was founded on the anthropological assumption that the white English were civilized, while the non-white indigenous were savage. The assumption developed into colonial discourse through systematic gathering of anthropological knowledge about the peripheries of the Empire. The knowledge system was flawed, which stressed the differences of the peripheral populations from the English and served as an inverted discourse on the Imperial Self rather than the description of the Other. Furthermore, the natives were heterogeneous, which rendered indistinct the racial and cultural differences between the English and the natives. Still, the aboriginals called Malays, who were comprised of many ethnic subgroups, needed to be deemed savage or inferior by the English in order to justify the English civilizing work or imperial ambition. Put differently, the representation of the English as civilized necessitated the (mis)representation of the natives as savage. In this context, Clifford's works contribute to systematic misrepresentation of the Malays, on which colonial discourse is founded, though not without self-contradiction. On the other hand, Conrad's novels that are set in the Malay Archipelago resort to a strategic misrepresentation that reveals the relativity of the discourse. Exploring the dilemma of denationalization to various degrees, Conrad's Malay texts problematize the (mis)representation of the indigenous as inferior, which is the basis of English claim to superiority.

A staple of feminist literary anthologies which was instrumental in reevaluating the writer Susan Glaspell, Trifles(1916) has received numerous comments from feminist scholars so far. Most of them tend to concentrate on the themes of female solidarity and justice challenging the androcentric system of law and order. Lacking in the plethora of thematic approaches to the play's feminist subject, however, are formal analyses considering the way in which the play's generic form assists in communicating such thematic concerns of feminism. An alternative to the typical scenario at the courtroom whose mistreatment of women must have loomed large to the young Glaspell as she revisited the old trial of a midwestern murderess which she had covered as a journalist for a local newspaper in Iowa, Trifles serves as a corrective to the courtroom dynamics offering a 'dramatic justice' as opposed to a strictly legal procedure. What this article discovers at the heart of this dramatic justice is the celebration of the unsayable, or what Wolfgang Iser termed negativity, of women's experience which has no room for reflection in the legal discourse at the courtroom tyrannized by the sayable and the evident. Examining how the dramatic form of Trifles gives a voice to the unsayable of woman's experience, which can not be properly represented at the courtroom governed by the straightforward and definitive male rhetoric, the article argues that the play is a better form than its fictional adaptation "A Jury of Her Peers"(1917) in that it syntactically suppresses the monopolizing operation of the verbal by giving precedence to the scenic and non-verbal which is constituted of setting, props, gesture and eye contacts. As a theoretical frame of reference with which to examine the modes of the unsayable in the play the article brings the concept of 'negativity,' defined by Iser as textual effects or modes of the unspeakable and unsaid, into the discussion of the taciturnity of the absent heroine and the non-verbal representation of drama.

Multiple discrete Hilbert type inequalities are established in the case of non-homogeneous kernel function by means of Laplace integral representation of associated Dirichlet series. Using newly derived integral expressions for the Mordell-Tornheim Zeta function a set of subsequent special cases, interesting by themselves, are obtained as corollaries of the main inequality.

Background: In the brain, the dominant primary motor cortex (M1) has a greater hand representation area, shows more profuse horizontal connections, and shows a greater reduction in intracortical inhibition after hand exercise than does the non-dominant M1, suggesting a hemispheric asymmetry in M1 plasticity. Methods: We performed a transcranial magnetic stimulation (TMS) study to investigate the hemispheric asymmetry of paired associative stimulation (PAS)-induced M1 plasticity in 9 right-handed volunteers. Motor evoked potentials (MEPs) were measured in the abductor pollicis brevis (APB) muscles of both hands, and MEP recruitment curves were measured at different stimulation intensities, before and after PAS. Results: MEP recruitment curves were significantly enhanced in the dominant, but not the non-dominant M1. Conclusions: These results demonstrate that the dominant M1 has greater PAS-induced plasticity than does the non-dominant M1. This provides neurophysiological evidence for the asymmetrical performance of motor tasks related to handedness.

Three-dimensional optimum design of coat-hanger die is performed using power-law and Carreau models. It is found that the three-dimensional optimum design algorithm shows good convergence with the non-Newtonian fludis. the nore realistic optimum design is accomplished by employing Carreau model with the three-dimensional design method. The effect of vixcosity modles is investigated by comparing the optimum manifold profiles and flow rate distributions of power-law and Carreau modles. Through the accurated viscosity representation of Carreau model, the effect of total flow rate on the optimum manifold profile is investigated.

A suitable representation for the conceptual simplicity of the data in statistics and signal processing is essential for a subsequent analysis such as prediction, pattern recognition, and spatial analysis. Independent component analysis (ICA) is a statistical method for transforming an observed high-dimensional multivariate data into statistically independent components. ICA has been applied increasingly in wide fields of spectrum application since ICA is able to extract unknown components of a mixture from spectra. We focus on application of ICA for separating independent sources and predicting each composition using extracted components. The theory of ICA is introduced and an application to a metal surface spectra data will be described, where subsequent analysis using non-negative least square method is performed to predict composition ratio of each sample. Furthermore, some simulation experiments are performed to demonstrate the performance of the proposed approach.

The discrete Gaussian-Hermite moment (DGHM) is a global feature representation method that can be applied to square images. We propose a modified DGHM (MDGHM) method and an MDGHM-based scale-invariant feature transform (MDGHM-SIFT) descriptor. In the MDGHM, we devise a movable mask to represent the local features of a non-square image. The complete set of non-square image features are then represented by the summation of all MDGHMs. We also propose to apply an accumulated MDGHM using multi-order derivatives to obtain distinguishable feature information in the third stage of the SIFT. Finally, we calculate an MDGHM-based magnitude and an MDGHM-based orientation using the accumulated MDGHM. We carry out experiments using the proposed method with six kinds of deformations. The results show that the proposed method can be applied to non-square images without any image truncation and that it significantly outperforms the matching accuracy of other SIFT algorithms.
