The present study was undertaken to evaluate the chemical characteristics of Asian dust (hereafter called "AD") particles with the aid of the most advanced micro-PIXE (Particle-induced X-ray emission) analytical technique. To this end, size-selected particles were sampled on a rural peninsula of Korea (Byunsan, 35.37N; 126.27E) during AD and non-AD periods in 2004. The coarse particle (> $2{\mu}m$) number density during an AD event were 170 times higher than those of the non-AD counterpart. The average net-count of silica in individual particles collected on AD event was roughly 11 times higher than that of non-AD counterpart. The X-ray net-counts of trace elements (Zn, Co, Mn, and V) were also considerably high in AD relative to the non-AD day. Particle classification based on the inter ratio analysis of elemental net-count suggests that a large portion of the coarse particles collected during AD event underwent chemical transformation to a certain degree. The visual interpretation of micro-PIXE elemental maps and elemental localization data in and/or on individual AD particles clarified the internal mixture of AD particles with sea-salt and artificial metallic particles.

기존 연구를 살펴보면, 창업가의 개인 특성과 기업가정신은 창업의도를 결정하는 중요한 요인이다. 그러나 선행연구에서는 개인적 특성을 집중적으로 다루며, 환경적 특성과 같은 외부적 요인을 간과해 온 경향이 있다. 창업결정에 있어 개인적 성향 뿐 만 아니라, 사회적 환경적 요인이 상당히 중요한 역할을 수행한다. 따라서 본 연구에서는 기존의 창업 관련 연구 결과의 공백을 메우고자 홉스테드 문화차원 이론을 적용하여, 개인적 특성과 문화적 특성의 조절효과를 연구하였다. 제시된 연구 모형에서 도출된 가설을 검증하기 위하여 실증분석 하였는데, 총 244개의 데이터를 수집하여 구조방정식 모형분석과 다중집단 비교분석을 실시하였다. 분석결과, 개인특성(내적통제, 자기효능감)은 기업가정신(자율성, 혁신성, 진취성)에 유의한 긍정적 영향을 미치는 것으로 나타났다. 또한, 홉스테드 문화특성요인 중 불확실성 회피 성향은 기업가정신과 창업의도와의 인과 관계를 조절하는 것으로 나타났다. 본 연구결과에 기초하여, 이론적. 실무적 시사점을 제시하면, 첫째, 창업에 있어 진취성이 매우 중요한 역할을 한다는 것이다. 따라서 창업관련 교육기관이나 창업매니저들은 창업가들의 진취성을 함양하는 방식으로 교육 커리큘럼을 운영하고, 이에 따라 훈련할 필요가 있다. 둘째, 창업의도를 정확하게 예측하기 위해서는 환경적 변수와 기타 개인적 변수의 상호작용을 함께 분석하는 것이 바람직하다. 마지막으로, 향후 기업가정신 연구에서는 기존에 제시된 기업가정신의 제 요소들을 포괄하여 요인들 간 상관관계를 종합적으로 분석하고, 정보의 중복 없이 효율적인 방식으로 기업가정신을 재조명할 필요가 있다.

In this paper, we explore a behavioral animation of artificial birds that have lived by doing an aggregate motion. We first model individual birds and then propose a behavioral model for an aggregate motion of a flock of birds. In order to represent realistically collision avoidance and flock centering among birds, which are necessary properties in a flock of birds, we consider motive of a flock of birds, and role, velocity, momentum, banking and internal characteristics of each bird. The paper presents the simulation result of the proposed model for a flock of 100 birds.

A simulation on the performance of a transcritical $CO_2$ heat pump system is carried out to investigate its characteristics for various operating conditions. Cycle simulation models are established for a steady-state simulation and are verified by comparing experimental data. Based on correlations and methods available in the literature, the processes in individual components of the transcritical cycle are simulated to analyze the performance of $CO_2$ transcritical heat pump system. The simulation models are good enough to predict the performance of a $CO_2$ transcritical cycle. Simulation results are provided to show the relative effects when varying the size of internal heat exchanger and the discharge pressure of a compressor.

300 MHz proton NMR spectra of human blood plasma were analyzed by deconvolution of spectrum, and we compared its results with Fossel's test in normal (15 cases), liver cancer (14 cases) , and other cancer (14 cases) groups. This analysis had enabled us to obtain dynamic characteristics of each individual lipoprotein. As a result of deconvolution method, the VLDL and chylomicron intensity level were found to be elevated in the patients with liver cancer. Moment ratio values of $CH_2$ resonance in the raw spectrum were found to be higher than the normal group for patients with, malignant tumors other than liver cancer. These differences between the three groups could not be found in the conventional Fossel's test. We could simulate plasma spectra by addition of spectra of individual lipoproteins through deconvolution method. Further clinical trials in larger populations and additional biochemical method may shed new light on many of clinical and biochemical interests for knowing characteristics about lipoprotein not separated from blood and the background of Fossel test.

Romanticists realized the ideals of a more fantastic and better society for the present day in which they lived; in addition, dress was an important medium of expression of this period. The Incroyables were a group that expressed eccentric forms and abuses of luxury through their clothing, centering around the second generation of financial elite groups during the French Directoire. Incroyables created their own fashion that expresses their new image in dress, expressing the intense personal innerity of life, which was influenced by the romanticism of pursuing an internal expression of the subjective and emotional individual. This study used a literature review to analyze the characteristics of the Romanticism expressed in the Incroyables fashion. The research results were as follows. First, it was an expression of an emotional desire for and ancient regime. Incroyables fashion were based on bourgeois nostalgia for the days of the ancient regime that resulted in an emphasis on individual and original human views. Second, it was also a hybrid of Romantic classicism. It was a form emphasizing body form where body beauty expressed a classical form through a dress under the influence of neo-classicalism that desires to return to nature.

The analysis of an art trend in the principle dimension starts by observing the object of work in the perspective of formative composition and recognizing it as a universal system. It can be said that it is consistent with an interpretation method for a form theory of formal history by Heinrich W$\ddot{o}$lfflin, a leading form critic in art criticism. Hence, the purpose of this study was to find out what are the formative principles in Renaissance Classicism as a design principle to be applicable to modern fashion by reviewing the formative characteristics of Renaissance Classicism Architecture with which W$\ddot{o}$lfflin directly dealt. As for the theoretical literature review, I used W$\ddot{o}$lfflin's theoretical framework and looked at the Renaissance Classicism Architecture that he studied and examined the possibility of utilizing his theory as a layout principle and the characteristics. As for analysis of design cases, I applied the aforementioned architecture layout principle to modern fashion and conducted case study analysis to delve into distinctive layout principles found in fashion. The study showed that the Renaissance Classicism Architectural Style is marked by linearity, planarity, closing and multiple unity: linearity was expressed in the observation form in fixed frontal view and an emphasis on a tangible silhouette homeogenous and definite line structures; planarity was achieved in the form of paralleled layers of frontal view element, planarity style, and identical and proportional repetition of various sizes.; closing signified the pursuit of complete and clear regularity, and architecture developed in a constructive phase through organizational inevitability and absolute invariability.; multiple unity was expressed in self-completedness and independent parallel of discrete forms and harmony of emphasized individual elements in a totality. Applying these layout characteristics of the Renaissance Classicism Architectural style and to see their individual expressive features, I found out that in adopting layout principles of the Renaissance Classicism Architecture to modern fashion, it turned out to be an emphasis of individual silhouettes, a flattened space, completed objects, organic harmony among independent parts: the emphasis of individual silhouettes was expressed in individual definitiveness of formative lines of clothes in accordance with body joints and an emphasis on formative lines of clothes; the flattened space was marked by single layer structure, planarity of elements of clothes, and listing arrangement by appropriate proportion.; the completedness of the objects was expressed by the stationary state where overall image is fixed, the construction of homogeneous and complete space, and absolute inevitability of internal layout in proportion; lastly, organic harmony of independent parts was stressed in independent completedness of each detail, and organic harmony of the whole. The expressive features would lead to a unique expression style of linear emphasis, proportion, constructive forms, and two-dimensional arrangement. The meaning of this study is follows: The characteristics of art school of thought are given shape by appling & analysing the architectural layout principles of historical art school of thought to modern fashion in the view point of formal construction dimension. The applied possibility of historical art school of thought as the source of inspiration about the fashion design is extended.

Sputter deposition followed by surface treatment was studied using reactive RF plasma as a method for preparing titanium oxide $(TiO_2)$ films on the FTO $(SnO_2: F)$ substrate for dye-sensitized solar cells (DSCs). Anatase structure $TiO_2$ films deposited by reactive RF magnetron sputtering under the conditions of $Ar/O_2(5%)$ mixtures, RF power of 600W and substrate temperature of $400^{\circ}C$ were surface-treated by inductive coupled plasma (ICP) with $Ar/O_2$ mixtures at substrate temperature of $400^{\circ}C$, and thus the films were applied to the DSCs. We have chosen a solar cell width as a variable of a large-scaled DSCs and confirmed electric characteristics of an individual cell. As a result, the higher the internal resistance of DSC becomes, the wider the width gets. Internal resistance makes it difficult to collect photoelectron generated from dye. Ultimately up sizing DSC causes the increase of internal resistance and then has a bad effect on the cell characteristics.

The purpose of this study is to establish a predictive causal model of codependency that is a main issue of family problem on the base of Triple ABC-X model which is a kind of family stress model. For the purpose of this study, we reviewed the concept and characteristics of codependency, affecting factors of codependency, and then reviewed the basic concept and logic of Triple ABC-X Model as theoretical viewpoint for the purpose of establishing a predictive causal model of codependency. We established it through examining main variables of codependency from Triple ABC-X Model. Main ingredients of the predictive causal model include boundary ambiguity, internal working model, internal and external locus of control, self-regard, social support, individual maladjustment etc. We established a predictive model of codependency basing on logic inferences among the variables. This study is expected to be used basic data to introduce some implications and for hereafter research.
