        홍익인간의 문헌자료 비교 고찰

        한용진 한국교육사학회 1993 한국교육사학 Vol.15 No.-

        This study is to make clear and identify the meaning of Honglk-Ingan. In this study, all the literatures an the history of Tankun which include the word of HongIk-Ingan were divided into three patterns: the literatures of Confucian or toadyism, that of Buddhism, and that of nationalism. In which I dealed with the six literatures and divided it as three types. Six literatures are Taepaek-Ilsa, Samsungki vol. Ⅱ, Samkuk-Yusa, Samsungki vol. Ⅰ, Jewang-Woonki, and a true record of the Yi dynasty's King Sejong. Especially, the first three literatures have a strong resemblance even though the two are the literatures of nationalism and the other one is that of Buddhism. As a conclusion, I insist that Honglk-Ingan means the ruling philosophy of Hahn-In and Hahn-Woong not of Tangun. And it is also the spirit of loving all human beings and the actural practice of education from generation to generation.

        The purpose of this paper is to analyze and illustrate Amazon’s distribution strategy and its success. This paper examines Amazon’s distribution strategy to demonstrate the importance of distribution strategy to the success and sustainability of its organization. The analysis indicates that the distribution strategy, including technology, shipping, and distribution infrastructure, is the most vital factor for the success of Amazon. Recognizing the importance of distribution systems, constantly innovating convenient and on-time delivery methods, and taking control of inventory and shipping activities have separated Amazon from its competitors and led Amazon to establish many different types of fulfillment facilities all over the world. Given Amazon’s continued growth that came with its constant strive for delivery and cost efficiency and customer satisfaction, it was inevitable that Amazon would eventually venture into the actual shipping business and emerge as the competitor of the traditionally well-known shipping companies such as DHL, FedEx, and UPS. The previous and current Amazon’s distribution strategies demonstrate that Amazon will continue to focus on developing and implementing new and creative distribution strategies to separate itself from the rest of the retail and e-businesses.

        국어 청자 존대어 체계의 기술을 위한 방법론적 검토

        왕한석 서울대학교 어학연구소 1986 語學硏究 Vol.22 No.3

        This paper attempts to sidcuss some methodological problems in describing the system of speech levels in Korean. It starts by briefly reviewing previous studies of speech-level classification done primarily by grammarians. The main body of the paper is devoted to presenting the actual organization of speech levels, which is a product of empirical research in a rural Korean village, Cihwali(pseudonym). This presentation consists of the identification of levels and their constituent forms, distinction between levels and its implication of class identity, the current honorific repertoire as a result of cutural contact, and synchronic variability and diachronic change in speech levels. And the whole description emphasizes treating honorifics in their broad ethnographic context. In summary and conclusion, the paper points out that most previous linguistic models on the organization of speech levels have overlooked the close relationship between social classes and patterns of honorific usage. It is addressed, therefore, that an adequate description of speech levels must be based not upon a regional dialect but upon a socially defined group whose members are expected to share both related linguistic and cultural knowledge.

      • 악성 갑상선 우연종의 임상상 및 초음파 소견의 진단적 가치

        강한욱,김광원,이병완,강보현,김형훈,김범진,정재훈,민용기,이명식,이문규 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

        연구배경: 최근 갑상선 초음파 검사의 빈번한 시행으로 갑상선 우연종의 발견이 증가하고 있다. 이러한 갑상선 우연종은 임상적으로 어떻게 접근하고 치료를 해야 하는지 적지 않은 문제가 되고 있다. 본 연구에서는 직경 1.5㎝ 이하의 갑상선 우연종의 유병률, 입상적 특징 및 초음파 특성, 그리고 가장 효율적인 진단적 접근에 대해 알아 봤다. 방법: 1999년 1월부터 2000년 12월까지 삼성서울병원 내과 및 일반외과로 갑상선 결절을 주소로 내원한 1457명을 대상으로 후향적 연구를 시행하였다. 우연히 발견된 직경 1.5㎝ 이하의 갑상선 결절을 가지는 환자들에서 갑상선 결절의 촉지 유무, 갑상선 기능검사, 항갑상선 항체, 갑상선 초음파 및 미세침 흡인세포검사, 99m^Tc 갑상선 스켄, 수술 조직검사 및 병기를 검토하였다. 결과: 분석한 갑상선 결절 1475예 중 갑상선 우연종의 유병률은 13.4%(198예)였다. 갑상선 우연종에서 악성률은 28.8%(57예)으로 나왔다. 양성 및 악성 갑상선 우연종에서 나이, 성별, 갑상선 기능검사, 결절 크기에는 의미 있는 차이는 없었다. 갑상선 스켄은 갑상선 우연종의 감별에 적합하지 않았다. 갑상선 결절의 초음파 지표 점수만이 양성 및 악석 갑상선 우연종의 감별에서 초음파 지표 점수의 민감도는 88.9%, 특이도는 74.4%, 양성 예측률은 92.4%로 나왔고 진단적 정환도는 85.5%였다. 갑상선암으로 수술을 받은 50명중 stage 1은 34명, stage 2는 6명, stage 3은 10명으로 대부분의 악성 갑상선 우연종은 낮은 TNM 병기로 나타났으나, 상당수에서는 국소 침범의 소견을 보였다. TNM 병기의 3기 환자 전부는 45세 이상이였고, 주로 갑상선암의 피막 침범에 의한 것이었다. 임파절 전이는 6명의 환자에서 나왔다. 결론: 악성 갑상선 우연종은 비교적 흔히 접할 수 있는 질환이며 양성 우연종과는 임상적으로 구별이 안 된다. 악성 갑상선 우연종은 발견 당시 대부분 낮은 병기이나, 갑상선의 피막 침범 및 임파절 전이가 상당수에서 발견되었다. 갑상선 우연종의 초음파 소견은 향후의 진단 방향을 제시하는 중요한 길잡이가 될 수 있다. 초음파 지표 점수 2점 이상의 갑상선 우연종에서만 초음파 유도 미세침 흡입검사를 권장한다. Background: High-resolution ultrasonography has made the detection of asymptomatic small thyroid possible. Recent increases in the detection of incidentalomas have created a clinical dilemma on how to properly manage such incidental nodules. We investigated the prevalence, clinical and ultrasonographic characteristics, and optimal diagnostic approach toward incidentally detected benign and malignant thyroid nodules of less than 1.5㎝ in size. Methods: A retrospective review was undertaken on the 1,475 patients who had visited Samsung Medical Center, Seoul Korea between January 1999 and December 2000. The review consisted of a physical examination of the thyroid gland, thyroid function test, antithyroid antibodies, thyroid ultrasonography, fine-needle aspiration biopsy, pathology and TNA staging of the incidentally detected thyroid nodules of less than 1.5㎝ in size. Results: The prevalence of thyroid incidentalomas was 13.4% and the malignancy rate within them was 28.8%. There were no significant differences in age, sex, thyroid function test and size between the benign and malignant incidentalomas. Ultrasonographic characteristics showed meaningful diagnostic value for the detection of malignancy in incidentalomas. Most malignant incidentalomas were of a low stage. Conclusion: Occult thyroid cancers are fairly common finding. There are no clinical difference between benign and malignant thyroid nodules less than 1.5㎝; however, ultrasonographic findings can be used to decision of optimal management strategies (J Kor Soc Endocrinol 17:649∼656, 2002).

      • 尹聖浩의 形式에 관한 硏究

        朴漢鎭 서울市立大學校 1990 論文集 Vol.24 No.-

        Western painting was indirectly introduced to Korea from Japan in the turbulent days of Japanese colonial rule of Korea. The Western painting was distorted on account of Japanese peculiar taste and the then Korean painters accepted it passively. This distortion was detrimental to the forming of Korean painting and the developing Korean modern art. Yoon Sungho(1904-1981) knew difficulty in adopting Western painting. And he experienced the tension between two sensibilities through his experiment of plastic form. After all Yoon resolved the crisis by a new state of sensibility. In doing so he recovered the original basic quality of Korean painting.

      • Covariant Harmonic-oscillator 波動函數의 直交關係

        洪翰植,金英子 慶北大學校 文理科大學 1978 文理學叢 Vol.5 No.-

        Orthogonality relations for the Kim-Noz covariant harmonic-oscillator wave function are discussed. It is shown that the wave functions belonging to different Lorentz frames satisfy an orthogonality relation. That is Φ_0^n(x)Φ^n'_η(x)d^4x=σ^nn'(1-β^2)^n+1/2 can be given following physical interpretalion: If η=0, the inner product becomes the three-dimensional inner product of non-relativistic quantum mechanics. If η≠0, this means that the rest-frame wave function should see the Lorentz contraction.

        小波動 分析을 활용한 計量 模型의 推定

        이한식 서강대학교 경제학연구원, 서강대학교 경제대학원 2005 시장경제연구 Vol.34 No.2

        小波動(wavelet) 이론은 최근 경제시계열자료 및 재무관련 자료의 분석에 그 적용이 확대되고 있는 분석도구이다. 본 연구에서 먼저 소파동 기법이 경제 · 재무 관련 자료의 실증분석에 기여한 측면에 관해 최근의 연구 결과를 점검하고, 이를 배경으로 다양한 경제 · 재무 관련 계량모형의 추정 및 검정에 소파동 기법이 어떻게 사용될 수 있는가에 대해 논의하고자 한다. 특히 소파동 이론의 다중주기 분석기법을 적용하여 시계열자료의 시간 · 주기별 관계를 분석하는 방법과 소파동 추정법을 활용하여 장기지속성을 나타내는 시계열자료의 분수차분계수를 추정하는 방법에 대해 자세히 살펴보고자 한다. 본 연구를 통해 경제 · 재무 시계열자료의 분석에서 소파동 이론의 유용성을 살펴봄으로써, 경제 · 재무관련 통계자료의 특징에 대한 분석뿐만 아니라 다양한 계량 모형의 추정을 위해서도 소파동 접근방법의 활용이 크게 확대될 것으로 기대된다. While wavelet analysis is a relatively new mathematical tool for signal processing, it has already been successfully employed in many disciplines. Although there are a few recent papers in economic application of wavelet analysis, the wavelet methodology has received little attention in empirical analysis of economic and financial data. In this paper, we discuss recent advances in wavelet methods for economic time series, and propose new approaches are also illustrated to present new evidence on the dynamics and potential interactions among time series. A simple wavelet methodology for seasonal adjustment is applied to Korean data, and the wavelet decomposition appears to work quite well in eliminating seasonality in economic time series. International spillover effects are discussed by investigating the relationships between high-frequency components in stock returns. In particular, wavelet regression methods are used to investigate the long-run PPP (purchasing power parity) hypothesis and the long memory properties in time-varying CAPM betas. Recent advances in wavelet methods discussed in this paper illustrate the usefulness of the wavelet analysis in various areas of economics and finance, although there still remains much room for potential application. Their applications in economics and finance are now growing fast, and their potential application areas should get wider in the future.

      • Quark Model의 群論的 背景에 關한 硏究

        洪翰植 慶北大學校 1977 論文集 Vol.23 No.-

        Elementary particle physics has made a long stride scince the introduction of the quark model, but it has many theoretical liabilities yet. This paper gives brief survey of the group theoretical back-ground of the theory, and looks forward for the improvement of the mathematical methods.
