We suggest the modified computing algorithm for raking ratio estimation under the assumption that the population total is partially known, and the sample total is completely known about survey variable in contingency table. We show that the proposed estimation procedure is useful to estimate the population cell count in this situation through an empirical study.

In this paper, We propose the feature-based 3D model Retrieval System. 3D models are represented as triangle meshes. A first simple feature vector can be calculated from hull. After looking for meshes intersected with the hull, we compute the curvature of meshes. These curvature are used as the model descriptor.

This paper proposes the calibration procedure for stratified Warner's randomized response model, which suggested by Kim and Warde (2004). It is shown that the proposed calibration estimator is more efficient than the Kim and Warde's model.

인터넷의 발전은 사용자에게 많은 혜택을 제공하는 한편 다양한 역기능 또한 가져오고 있다. 이러한 역기능을 제거하기 위해서는 온라인 상에서 사용자의 나이를 확인하여 각 연령에 맞는 콘텐츠를 적정하게 제공하여야 한다. 현재 온라인 상에서 나이를 검증하는 기술들은 다양하게 개발되고 있으나 각 기술들간에 나이 정보를 공유하는 기술이 제공되어 있지 않아 효과적인 대처가 어려운 상황이다. 그러므로 나이 정보 공유를 위한 연구개발이 조속히 수행되어야 한다.

In this paper, we will consider the periodic stationary Stokes equations on Rⁿ. For the cube of the period, we set Ω = ∏ⁿ_i=1(0, L_i). And we will study the stability of the solutions on various functional spaces, for the Stokes equations on Rⁿ.

This paper presents Reflectance Transformation Imaging (RTI) as a tool to support the study of paintings and authentication. Manufacturing techniques of the artist are reviewed through the comparison between liberal perspectives and digital imaging techniques. In this study, RTI was applied to focus on the detailed textural information of eight paintings by Korean artist Lee Ji-ho. The RTI result visualizes shallow reliefs of brush strokes and different mediums on the surface technically enhanced through imaging filters, and these morphological textures on the surface act as a key factor in understanding the characteristics of the artist. The surface morphology and art criticism work as qualitative indicators to analyze the change of artistic techniques through time, and the usage of different mediums. The results of this study confirm that the RTI technique can be used as an analysis device in the study of paintings.

The idea that medicine itself imposes certain obligations upon the physician probably originated in Greece. It is Socrates in the fifth century BC who first discussed medical professionalism. Socrates said that no physician should seek the advantage of the physician but of the patient. For the physician was a ruler of bodies and not a money-maker. However, it is Hippocrates, the contemporary of Socrates and the Father of Medicine, who founded medical professionalism education and professional medical ethics. The professional spirit of Greek physicians is summed up in the magic phrase 'love of humanity.' In Epidemics I, Hippocrates expressed hope that physicians would help patients, or at least do them no harm. He also said, "Life is short; Art is long" in The Aphorisms. Here he described the reflective philosopher and the practiced physician. At once he sang the shortness of human life and the extent of the medical arts. Moreover, he made students swear by the gods that "I will keep pure and holy both my life and my art." The Oath can serve as a coherent starting point and organizing framework for medical professionalism education and professional medical ethics. We need to have an opportunity to employ this fascinating text in teaching medical professionalism and medical ethics. In this article, the author asserts that the Hippocratic Aphorism (Life is short; Art is long) and The Oath, the most famous work of the entire Hippocratic collection, should be used for medical professionalism education.

예술의 소통 및 역할 확장의 문제는 예술의 중요한 담론 중 하나이다. 한동안 소수 엘리트 층 위주의 예술 향유 및 사회에서의 역할소외를 극복하고자 많은 노력들이 시도되기도 했다. 이와 같은 와중에 미디어아트는 그 형식적 특성상, 다양한 놀이콘텐츠 및 산업적 맥락 속에서 대중과 소통하고 사회 속 친근한 예술로 다양한 역할확장에 기여하였다. 본 연구에서는 한 단계 더 나아가 미디어아트가 사회 속 현안 한 문제들에도 접속하고 활용될 수 있는지 등의 가능성을 '미디어아트정보시각화'를 통해 살펴본다. 일반적인 정보시각화 영역은, 정보 전달의 명확성에만 치중되어 있다. 그래서 수많은 정보들을 직관적으로 파악하는 데에 효과적이다 하지만, 유저의 감성이 날로 증가하는 시대에 경직된 시각표현은 유저 친화적인 부분에 있어 많은 부분 보완되어야 하며, 정보 전달의 효과성에만 집중되어 개인 정보보호 등의 2차적 사회문제 발생을 보완 하여야 하는 과제를 갖고 있다. 그에 따라 본 연구에서는 일반적인 정보시각화와 비교해, 미디어아트의 예술적 특성과 융합하여 '미디어아트정보시각화'가 어떻게 창의적으로 사회 문제에 접속하고 강점으로 관여할 수 있는 지 사례 작품들의 특징을 분석한다. 그리하여 예술의 역할 확장모색 및 예술융합을 통해 사회 현안에 대한 창의적 접근 그리고 일반적인 정보시각화에서 놓치고 있는 영역을 보완, 확장된 가치를 제공할 수 있음을 고찰한다.

본 연구에서는 고등학생들의 과학철학적 관점이 어떤 철학(경험주의, 합리주의, 구성주의)에 근접해 있는지와 어느 구성주의 철학자(포퍼, 쿤, 라카토스, 툴민)의 관점에 근접해 있는지를 알아보았다. 또한 정량적 방법을 통해서 성별, 문 이과별, 과학철학에 대하여 접해본 경험여부에 따라 유의미한 차이가 있는지 분석하였다. 연구 결과, 학생들은 전체적으로 특정한 철학적 관점에 치우쳐 있지 않았으나 과학철학을 접해 본 경험이 있는 학생들이 경험주의 관점을 가지고 있었다. 또한 구성주의 철학자적 관점에 있어서는 남학생들이 쿤의 관점에, 이과 학생들이 포퍼의 관점에 근접해 있는 것으로 나타났다. 학생들의 과학철학적 관점은 본 연구의 정량적인 방법 외에 정성적인 방법으로 차후의 연구가 요구된다.

The research was conducted based on the 1012 cases questionnaire for the purpose of to evaluate the change effect of university student's consciousness and behavior before and after lecture on environmental problems. And this questionnaires were performed with self-administered by the university student who made a application for liberal arts related to environmental subjects. The results were as follows. According to the analysis results the most students responded that the most serious problem of environmental pollution before the lecture on environmental education was a genetic modified organism(3.64/4.00), but the most serious problem of environmental pollution was changed to the topic of water pollution(3.96/4.00) after the lecture on environmental problem. And also according to the analysis results dributed by gender were that boy students show a higher concerning(170%) than that of girl students(150%). The most good results obtained after lecture on environmental problem were water pollution(23.0%), air pollution(11.5%), waste material pollution(10.9%), food additives (10.0%), genetic modified organism(8.0%), endocrine disrupter(7.5%), respectively. And according to the analysis results distributed by a grade were that the concerning of a low grade(freshman, sophomore)were higher than that of a high grade(junior, senior) in the topic of water pollution, air pollution, waste material pollution. But there were high level of awareness on the topic of food additives, genetic modified organism, endocrine disrupter to the all students(freshman to senior). And according to the analysis results distributed by a major field of study were that students who major in art & athletics, liberal art and etc(public health) were show a deep concerning than that of science & engineering. Finally, the environmental education during the university class were effectively contribute to increase the awareness of the seriousness of environmental pollution problem(8.2%) and also contribute to the practical life after class also increase their consciousness of environmental problem(59.8%).
