Spin Oscillations in a Free Molecular Magnet

김광희 한국물리학회 2012 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.61 No.11

We show that the macroscopic quantum beats of the magnetization can be produced by using a sound wave in a free single-molecule magnet. Employing the rotating wave approximation and a numerical method, we derive the Hamiltonian of a rotated two-state spin system and present superpositions of spin and rotational states. A parameter involving the energy gap and the moment of inertia plays an important role in determining the shape and the period of the quantum beat. Also, such a beat structure is governed by the total angular momentum and the coupling of the single-molecule magnet to the substrate. The condition for a pronounced beat with a large period is discussed.

미․중․일 3국에 대한 수입 상위 20품목의 위상과 그 실태 분석(1995-2010년)

김광희 한일경상학회 2011 韓日經商論集 Vol.53 No.-

As everyone knows, the US, China and Japan Korea’s three major import & export partners, and the ratio of the exports of these three countries covers 41.8% of 466.38 billion dollars of exports to the world. In addition, the weight of the imports of these three countries from the world is high enough to cover 41.5% ratio of 425.21 billion dollars. For this reason, in time of bringing up the import & export issues of Korea, it may be safe to say that it is almost impossible to have a discussion itself from the start without a detailed analysis and review of the three countries, the US, China, and Japan. Under such a recognition, this study aims at drawing the response strategy to several problems by analyzing the transitions of competitiveness in imports & exports up to the present since 1995 with its focus on the top imported 20 items from the US, China, and Japan. As the result of the analysis, the movement of rapid changes in major imported items from China was detected, and actually even the nature of the imported items affected is quickly moving from the agricultural & fishery items, which were featured in initial imports from China, to steel & metal products, machinery, and electronic & electrical products. This trend might be partially caused by the domestic corporation’s on-site launching in China, but, above all, it suggests Chinese corporations’ competitive strength is being intensified day by day. Thus, it’s high time for Korea to inquire into and promote the export strategy on China on the basis of a long-term standpoint. Next, as for the imported items from the US, mostly agricultural products are featured excluding the items related to aircraft; on the contrary, in case of the imported items from Japan, our industrial circles’ vulnerability to Japan is clearly exposed in that the imported items from Japan feature the parts & materials. It seems to be urgent for Korea to set up a strategy of ‘choice & concentration’, which gives weight on parts & materials industry, for fostering import & export with Japan.

‘아리랑’을 소재로 한 공연콘텐츠 개발방안 : 전남도립국악단을 중심으로

김광희 문화예술콘텐츠학회 2013 콘텐츠 문화 Vol.3 No.-

‘아리랑’은 한국의 대표적인 민요이다. ‘아리랑’은 기본적으로 ‘아리랑, 아리랑, 아라리요’를 포함한 후렴구와 가사로 이루어진 노래 군을 가리키며, 지역마다 독특한 ‘아리랑’이 전승된다. ‘아리랑’의 노랫말은 다양한 주제를 다루며, 단순하면서도 문학적인 가사와 음률 덕택에 즉석에서 지어 부르기, 따라 하기, 함께 부르기 등이 쉽다. ‘아리랑’은 인간 창의성, 표현의 자유 등을 존중한다는 데 그 특징이 있다. 또한 ‘아리랑’은 영화, 뮤지컬, 춤, 문학작품 등 다양한 예술분야의 주제로 활용되고 있다. ‘아리랑’은 이러한 연유로 2012년 인류무형문화유산으로 등재되었다. 본 연구는 ‘아리랑’의 가치와 특성을 알아보고 각 지역의 아리랑 콘텐츠 활용사례 및 정부의 지원정책을 파악하여 이를 바탕으로 ‘전남도립국악단’의 ‘아리랑’을 소재한 공연콘텐츠 개발방안 제시를 목적으로 한다. ‘전남도립국악단’은 시설투자 보다는 ‘아리랑’ 관련 프로그램 개발 및 ‘아리랑’ 활용 프로그램의 질적인 향상에 초점을 맞춰 나가야 한다. 공연콘텐츠 프로그램 개발 방안으로는 첫째 ‘아리랑’ 브랜드 개발, 둘째 ‘아리랑’ 공연프로그램 개발, 셋째 ‘아리랑’ 학술조사 및 아카이브 구축, 넷째 ‘아리랑’ 교육프로그램 마련, 마지막으로 남북이 공감할 수 있는 ‘아리랑’ 프로그램 개발을 제시하였다. 향후에는 보다 심층적인 연구를 통해 실증적 프로그램 개발이 필요하다. 우리의 ‘아리랑’이 유네스코 인류무형유산으로 등재되면서 많은 지원정책과 계획들이 쏟아지고 있다. 이 같은 계획이 국가적인 이벤트에서 흔히 볼 수 있는 말의 성찬(盛饌) 이 되지 않기 위해서는 ‘아리랑’을 활용한 다양한 프로그램의 개발·보급, 관계기관의 지속적인 지원과 국민적 관심이 끊이지 않도록 모두가 노력해야한다. "Arirang" is Korea’s one of the most well known traditional folk songs. It is a song that uses "Arirang, arirang, ara-ri-yo" in its chorus and lyrics. Depending on the different regions of Korea, each distinctive regional "Arirang" has been inherited down. The lyrics of "Arirang" deal with a variety of different subjects. Due to its simple and literary lyrics and melody, it is very easy to ad-lib the song, easy to sing after hearing it once, and also very easy to sing as a group. The characteristic of "Arirang" is that it respects the creativity and the freedom of expression of one individual. Moreover, "Arirang" is dealt and applied in various movies, musicals, dances, and literature pieces. For the above reasons, "Arirang" was registered as the Intangible Cultural Heritage of 2012. This report deals with the value and characteristics of "Arirang." It will look at the practical usage examples of “Arirang” contents according to each region and the government’s support policy. Through this, it is targeted to provide development methods for the ‘Jeollanamdo Provincial Gugakdan“ using “Arirang” as the performance content. “Jeollanamdo Provincial Gugakdan” must focus on developing “Arirang” related program and enhancing the quality of “Arirang” applied programs rather than focusing on facility investment. For the development method of performance contents programs, the below have been provided. First, to develop a brand of “Arirang.” Second, to develop “Arirang” performance programs. Third, to establish an academic research and archives for “Arirang.” Fourth, to develop an educational program on “Arirang.” Last, to develop an “Arirang” program that can be well acknowledged by both South Korea and North Korea. In the near future, a practical program needs to be developed through a more in-depth research. Many policies and support plans have come up after “Arirang” was registered as the Intangible Cultural Heritage by UNESCO. In order for this plan to be successful and not be a rain in the parade that can often be seen in national events, there needs to be development-distribution of a lot of different programs using “Arirang.” Also, everyone has to work together so that the related agencies’ continuous support and public interest does not fade away.

다중회귀신경회로망을 이용한 시계열패턴의 예측에 관한 연구

김광희,강치운 동의공업대학 1998 論文集 Vol.24 No.1

In this paper, the Multiple Recurrent Neural Network(MRNN). which is a dynamic neural network, is proposed and is applied to predict a time series. The prediction performance of the MRNN measured by the normalized mean square error(NMSE) is superior to that of the adaptive time-delay neural network(ATNN) which adapts its time-delays as well as its synaptic weights. The MRNN is based on the multi layer perceptrons(MLP) with two hidden layers and several feedback routes with different delays added to the MLP. In this configuration several previous activation values in the upper hidden layer are fed back into the lower hidden layer. The conventional error back-propagation is used to learn the MRNN. In the experiments we know that the network performance is more affected by the number of feedback routes than the number of nodes or layers. Since the prediction error of the MRNN with 14 feedback routes is smaller than that of the ATNN, we conclude that the added feedback routes improve the context learning ability of the network. However, there are many problems, which must be solved in the future concerning the dynamic behaviors of the MRNN. The architecture of the MRNN is simpler than that of the feedforward time-delay networks but the context learning ability of the MRNN can be better. The MRNN. therefore can be used to recognize time-varying patterns like speech signals in time domain without any other preprocessing.

The purpose of this study is to examine the effects of the selection methods of input variables and the number of data on the accuracy of cost estimation using neural networks(NNs) in apartment housing projects. The acquired 10 input variables was classified into three categories(concept, pre-design, preliminary design stage). And then input variables for constructing the neural networks model was selected by regression analysis, principal component analysis(PCA), genetic algorithms. The neural network models were constructed by changing the number of data and the number of input variables according to the method for selecting optimal input variables and project definition. Using the NNs for cost estimation, the method that selects the input variables by regression analysis could enhance the accuracy. The relationship also could reduce time because the range of accuracy is expected
