Amazon’s Distribution Strategy: Doing the Right Things

Hahn,Yoonah,Youn,Myoung-Kil,Kim,Dongho 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-

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.

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.

미국미술의 다양성에 관한 연구 : 1994-95년도 New York 지역을 중심으로

朴漢鎭 서울市立大學校 1996 論文集 Vol.30 No.-

American art has a diversity. I can confirm it on viewing 17 exhibitions held in the New York area in 1994-95. And I make an analysis of it focusing on affinity, experimentation and conservatism of the art world. American art is vigorous throughout the country on account of the affinity between artist, populace, critic and museum(gallery). There are various supporting system to the art, for example, the national endowment for the arts, art foundation and patron etc. Non-profit and profit galleries are centers of art activities. There is experimentation of art on a diversity. First of all American art constantly persue the meaning of the human body. The body seems to be expressed an actual proof without spiritual significances. Another experimentation is also possible to develop incessantly a new plastic form. It is exemplified in the case of Ma가 Tansey's <representation> and <pseudorealistic imitation> of Peter Fischli and David Weiss. The exclusive mindedness comes into question in the republic of American art critics. It is undesirable to make an issue of the <third world> tradition at the works of Byron Kim owing to his native Korean parents. This is a case of prejudice anainst the minority in order to make a discrimination between two art world. American art is different from ours. The <others> is mixed in <ours>. We must understand clearly the truth and false of the diversity in American art. The presence of the <others> serves as a momentum to discover and develop the <ours>.

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.

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.

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.

Background: Hemorrhage itself has been shown to produce abnormalities in immunity, particularly depression of the lymphocyte function. In order to better examine the amount of hemorrhage required to suppress the lymphocyte function, we determined the effect of graded fixed-volume hemorrhage on splenocyte proliferation and the lymphocyte subpopulation. Methods: Male Sprague-Dawley rats(weight,350∼400 g) were anesthetized, subjected to hemorrhages of 7.5 ㎖/㎏, 15 ㎖/㎏, and 22.5 ㎖/㎏ by percutaneous cardiac puncture with ㎖/㎏ needles, After 1, 2, 4, and 7 days, animals were killed to obtain the blood and spleen. The splenocyte proliferative capacity was measured by using the tritiated thymidine incorporation technique, and the peripheral lymphocyte subpopulation was determined using flow cytometry with the following monoclonal antibodies: T cell(CD3+), T helper cell(CD4+),7 cytotoxic cell(CD8+), and B cell(CD45RA+). Results: Hemorrhage of 7.5 ㎖/㎏ did not induce depression of splenocyte proliferation. However, for hemorrhage greater than 15 ㎖/㎏, the splenocyte proliferative capacity was significantly depressed at 2 days after hemorrhage and recovered at 4 days. Hemorrhage induced no changes in the relative percentage of lymphocyte subpopulations and in the number of each cell in peripheral blood. Conclusion: This study suggests that cellular immunity is depressed at 48 hrs after a hemorrhage greater than 15 ㎖/㎏ without any change in the peripheral lymphocyte subpopulation.

In deriving Einstein's fundamental equation of gravitation, R_μν-1/2 g_μνR=-KT_μν, firstly a brief survey of important tensor relations is given. Secondly Einstein's curvature tensor R_μν, curvature scalar R=g^μνR_μν and scalar density √-gR are introduced, and the Hamiltonian derivatives δ(√-gR)/δoj^ik, δ(√-gR)/δg^ik, δ(√-gR)/δg_ik are sought. It was shown that their invariant divergences vanish. On the other hand the "energy tensor of matter" T_μν which combines the enrgy density of the electromagnetic field and that of ponderable matter was introduced, and it was shown that the divergence of the corresponding mixed tensor vanishes. In analogue of Poisson's equation, these two quantities were equated. Lastly the important implications of this equation were enumerated.
