김용각 남서울대학교 2017 국내석사

인간은 오래전부터 보다 더 나은 삶을 살기 위하여 끊임없이 노력해왔다. 이에 오늘날의 현대인들은 각자 자신만의 생활의 질을 높이고 편안한 생활을 누리기 위해 다양한 소비성향을 지니게 되었고 주거에 있어서도 흔하지 않고 남들과 다른 개인 인의 취향에 맞는 개성있고 독창적인 디자인을 선호하며 자신의 공간을 고급스럽게 연출하고자 한다. 공간을 장식하는데 있어서 타일은 중요한 역할을 담당한다. 건축물의 실내·외장재로 벽과 바닥 등 여러 용도로 다양하게 쓰이는 타일은 현대인들이 살아가는 공간인 주거공간, 업무공간, 상업공간, 문화공간을 쾌적하고 안락하게 만들어 주는 우수한 마감 재료이다. 그리고 이렇게 공간장식에 있어 기본적이며 중요한 역할을 담당하는 타일은 수많은 예술가들의 예술적인 매개체로도 활용되고 있다. 본 연구자는 타일을 더 고급스럽고 세련된 미적 도구로써 시각적인 즐거움을 줄 수 있는 예술적 매개체가 될 수 있도록 연구하고자 한다. 또한 기존의 타일형식에서 벗어나 현대인들의 개성과 취향, 욕구를 충족시킬 수 있고 제작자의 생산성에도 영향을 줄 수 있는 선택의 다양성을 줄 수 있도록 하고자 한다. 따라서 본 연구의 목적은 다음과 같다. 첫째 옵티컬 아트의 패턴에서 보이는 기하학적인 반복성과 규칙성을 타일에 적용하여 타일 자체로도 공간장식에 있어 미적으로 훌륭한 역할을 하도록 하고자 한다. 둘째 평면이 아닌 부조로 입체화하여 조명과 함께 빛과 그림자를 활용하여 착시효과와 리듬감 등을 높이고 이를 구현하여 다채로운 옵티컬 아트 타일 디자인을 제시하고자 한다. 연구방법은 타일과 옵티컬 아트의 일반적 고찰을 통해 이론과 예술의 배경을 서술하고 본 연구자의 작품제작 배경과 제작방법과 연계된 현대화된 방법론을 토대로 제작된 옵티컬 아트 부조타일을 보여주고자 한다. 본론에서는 첫째, 타일의 기본적인 개념과 역사, 종류에 대해 알아보았고 둘째, 옵티컬 아트의 디자인적 고찰을 통해 시각적 효과를 분석하여 도자로 표현한 작품들을 살펴보았다. 셋째, 작품 제작에서는 보다 더 정확한 설명과 진행과정을 보여주기 위하여 디자인 배경과 제작 과정, 작품 해설로 분류하여 서술하였다. 디자인 배경에서는 옵티컬아트의 시각적 효과를 분석한 것을 바탕으로 연구자만의 패턴을 어떻게 표현할 것인지에 대해 서술하였다. 제작 과정에서는 3D(Three Dimensions)프로그램을 이용한 디자인 및 모델링 과정과 CNC(Computer Numerical Control)조각기를 활용한 원형 제작을 중점으로 석고를 이용한 몰드 제작, 성형, 시유 및 장식의 과정으로 분류하여 서술하였다. 작품해설에서는 각 타일 디자인의 콘셉트와 제작에 있어 사용된 소지, 사이즈, 기법, 컬러등 기본적인 내용과 완성된 작품이미지, 도면으로 자세하게 설명하였다. 본 연구를 통해 공간장식에 있어 중요한 매개체인 타일이 옵티컬아트의 기하학적인 반복성과 규칙적인 패턴으로 정확하게 디자인하고 제작하므로 종합예술인 건축의 미장에 큰 역할을 할 수 있음을 알 수있다. 예술성과 장식성을 충족시켜 보다 더 훌륭한 예술작품의 한 장르로 발전될 수 있을 것이다. 본 연구에서 사용한 디지털 기술과 접목시켜 다양한 디자인과 융합 연구 된다면 더 다양하고 정확하며 세련된 미래 지향적인 타일이 연구되어질 수 있을 것이다. 주제어 : 3D프로그램, CNC조각기, 타일, 옵티컬 아트, 패턴, 도자 Human has tried endlessly to live a better life since long ago. Hereby today’s modern people have various consumption tendencies to raise the quality of life and enjoy the comfortable life, and prefer the characterful and originative design according with individual taste different from others when it comes to the house. They want to direct their space luxuriously. The tile plays an important role as a representative element in decorating the space. Tile used diversely for many uses such as the wall and bottom as the interior/exterior material of the architecture is the excellent finish material making the residential space, work space, commercial space, and culture space pleasant and comfortable where modern people live. A number of artists are using the most basic and most important tile in decorating the space as the artistic medium. The purpose of this researcher is to conduct a study for the tile to be the artistic medium that gives the visual pleasure as the more luxurious and refined aesthetic tool. Another purpose is to give the diversity of the choice to influence the productivity of the producer while meeting the individuality, taste, and needs of modern people escaping from the existing tile form. Therefore, the purpose of this study is as follows. First, the geometric repetitiveness and regularity shown in the pattern of the optical art will be applied to the tile to make the tile play a great role aesthetically in the space decoration. Second, the light and shadow will be used with the lighting after making it three-dimensional by relievo not the plane in order to raise the optical illusion effect and rhythmic sense and various optical art tile design will be shown. The background of the theory and art will be described through the general consideration of the tile and optical art and the work production background of this researcher and the production method will be introduced to introduce the modernized methodology, and the relievo tile using the effectively expressed optical art effect will be shown. In the body, first, the basic concept, history, and kind of the tile were examined. Second, the works expressed by pottery were examined by analyzing the visual effect through the design consideration of the optical art. Third, the work production was classified into the design background, production process, and work interpretation in order to show the more exact explanation and the progress process. In the design background, it was described how to express the researcher’s own pattern based on what analyzed the visual effect of the optical art. The production process was classified into the mold production using the plaster, molding, glaze, and decoration focusing on the design & modeling process using the 3D(three dimensions) program and the circle production using the CNC(computer numerical control) carving machine. In the work interpretation , the work was explained in detail by the basic contents such as ceramic, size, technique, and color, and by the completed work image and floor plan in regard to the concept and production of each tile design. It is confirmed through this study that the tile which is the important medium in decorating the space is exactly designed and produced by the geometric repetitiveness and regular pattern of the optical art, so it can play a great role to plastering of the architecture which is the synthetic art. It will be able to develop into a genre of the greater artwork by satisfying the artistry and fanciness. If the tile is studied complexly with various designs by engrafting into the digital technology used by this study, the more diverse, exact, refined future-oriented tile will be able to be researched. key word : 3D Program, CNC Machine, Tile, Optical Art, Patten, Ceramic

金容珏 국민대학교 대학원 2003 국내석사

인터넷의 보급에 따라 실시간 운영체제에서 이더넷을 지원해야 할 필요성이 커지고 있다. 그러나 이더넷을 지원하는 대부분의 실시간 운영체제는 상용 프로그램이므로, 이를 이용할 경우 제품의 원가를 높이는 원인이 된다. 따라서 공개된 실시간 운영체제 환경에서 TCP/IP 스택을 구현하여 이더넷을 지원하도록 하는 연구가 필요하다. 본 논문에서는 공개된 실시간 운영체제인 uCOS를 탑재한 마이크로프로세서 보드에 이더넷 컨트롤러를 탑재하고, BSD코드를 기반으로 하고 있는 uCIP을 이식하였다. 개발된 시스템에서는 uCIP에서 제공하는 ARP, ICMP, UDP, TCP 등의 프로토콜이 구현되었다. 또한 uCIP의 DHCP 프로토콜의 미비한 점들을 개선하여 정상적이고 안정적으로 DHCP 프로토콜을 지원하도록 하였다. As Ethernet-based Internet has come into wide use, it is more necessary that RTOS<Real-Time Operation System) supports Ethernet. Most RTOS supporting Ethernet is a commercial program which causes rising of cost of product when it is used. So, the investigation to support Ethernet using TCP/IP stack under an opened RTOS, uCOS, is required. In my thesis, Ethernet controller and uCIP based on BSD code is loaded on the Microprocessor using uCOS. I inplemented a system with ARP, ICMP, UDP, and TCP supported by uCIP. I also realized DHCP protocol stably.

證券會社 商品株式管理에 關한 問題點과 改善方案 : S증권의 사례를 중심으로

The purpose of this thesis is to investigate problems in the stock portfolio management of Korean securities companies, the net worth of which has been rapidly expanded through a number of capital injections since 1991. It is hoped also to provide some remedies based on advanced investment techniques given the nation's stock market environments. This thesis concentrates on the Companies' basic portfolio strategy, organization, and decision-making procedure in order to analyse the Companies' stock portfolio management. To base the analysis on reality, I examined the portfolio strategy and the 1991-1995 results of S Securities. The Main contents of this thesis are as follows: Firstly, the Companies view their stock portfolio management as asset management due to the non-diversification of financial market instruments in Korea. The Companies also maintain two conflicting portfolio strategies, i. e. profit maximization and other operation support. As a result, their efficiency in both profit maximization and market price stabilization appear to be unsatisfactory. Secondly, despite the expanded size of their stock portfolios, the Companies rely largely on the experience and subjectivity of individuals for their portfolio structure, decision-making procedure, and information analysis. As a result, their portfolios are vulnerable to various systematic or non-systematic risks and their fundamental and technical portfolio analysis remains at a stage of basic data processing. Thirdly, in order to maximize profitability, their excessive support to the Companies' operation should be avoided by structuring relatively conservative portfolio, and the incentive bonus system should be introduced based on results to give responsibility and incentives to fund managers. The Companies should also concentrate on developing advanced analytic techniques by establishing a research data base and a trading room. In conclusion, the Companies should manage their stock portfolio with a view to stabilizing the stock market as a market maker together with maximizing profits by curing the above problems and by developing scientific portfolio management.

일본인 학습자 대상 한국 언어문화 교육 방안 연구

김용각 부산외국어대학교 교육대학원 2020 국내석사

In this study, I considered Korean language and culture education methods for Japanese learners. In the meantime, there has not been much education and research on specific language learners in Korean language education, and this paper is meaningful in that it proposes to develop Korean language and culture guidance methods and evaluation questions for Japanese learners. Compared to other countries, Korea and Japan have many cultural similarities, and in terms of language, vocabulary and grammar are similar, resulting in more expressions of misuse due to interference in the mother tongue. In addition, since the motivation and purpose of learning by Japanese Korean learners are mostly interested in Korean culture, I decided that education on language culture was very important in Korean language education for Japanese people, so I conducted this study. Specifically, I discussed the status of Korean language and culture education and the status of language and culture education in Korean Japanese language education in two aspects : application in class and reflection in TOPIK test. First, the application of Korean language classes was divided into verbal and non-verbal behavior cultures, and then the guidance was presented according to the level of Korean language learning. Specific guidance measures include 1) New Year's greeting education using scenarios(startup), 2) ○×quiz for preventing misuse by direct translation(second and intermediate), 3) New words education using speed quiz games(middle and high level), 4) Busan dialect education using movie 'Friend'(advanced), As a way to educate nonverbal behavior culture, 1) Non-verbal behavior education on promise through demonstration(advanced), 2) Comparative education on non-verbal behavior between Korea and Japan through TV scene capture(advanced), A total of six methods of guidance were presented as examples. Second, for reflection in TOPIK test, the Korean language and culture related questions corresponding to TOPIK II were developed (a total of 9 presentations and 10 questions were developed) and the types of questions were proposed in various forms, including dialogue format and blog format, in addition to the existing reading fingerprint format. The reason for presenting the development of assessment questions as an educational method is that the assessment is not only used as a means of measuring the learner's learning level or the effectiveness of teaching methods by professors, but also helps to understand the various problems of education and set the direction of the curriculum. The Korean language culture-related evaluation questions presented in this study can be seen as questions corresponding to TOPIK II, and the texts presented can be seen as those that can be used not only in the reading area but also in the listening area. Through the above-mentioned research results, the paper expects to contribute to the development of language and culture-related textbooks and teaching methods in Korean language education in the future, as well as to diversify the types of Korean language and culture questions in TOPIK tests and increase the percentage of questions reflected in the questions.

Miller 積分器에 있는 抵抗은 한個의 Capacitor 와 두個의 Switch로 바꾸어 줄 수 있다. 이 S·C ( Switched Capacitor)는 抵抗에 比해 溫度特性 및 線型特性이 좋고 실리콘面積이 적게 所要되는 利點이 있다. 本 論文에서는 基本的인 S·C 回路의 原理와 Miller 積分器 및 1st-order low-pass Filter를 S·C 로 實現하는 一般的 方法을 檢討한다. 特히 傳達函數를 중심으로 位相差를 줄이는 方法과 S·C 로 實現하는 경우 誤差를 조사하여 使用 可能한 周波數 範圍를 추적한다. 實驗을 通해 Miller積分器와 S·C 積分器의 應答特性이 비슷함을 確認하고 1st-order low-pass Filter를 S.C濾波器로 實現하기 爲한 이상적인 素子들의 값을 調査하였고 實用化에 도움이 되도록 理論과 實驗結果를 比較檢討하여 S·C low-pass Filter의 Switching frequency와 밴드폭사이의 制約條件을 檢討하였다. Registor in Miller Integrator can be substituted with one capacitor and two switches. This switched capacitor has not only better temperature and linear characteristics, but also smaller capacitor area than registor does. This thesis reparesents the basic principle of S.C. circuit and general methods by which Miller Integrator and 1st-order low-pass filter is converted into S.C. Especially, it is studied on the method to reduce the phase shift error, and available frequency range is obtained by analyzing errors in S.C. Through experiment, it is proved that response characteristics of Miller Intergrator is similar to that of S.C. Intergrator, and the ideal value of the elements to convert 1st-order low pass filter into S.C. filter is determined. And also restriction conditions between switching frequency and bandwidth in S.C. low pass filter are reviewed by analyzing the theoretical and experimental results so that they can be some help in utilization.
