Shakespeare, in all of his plays, shows his concerns of order and chaos resulted from the destruction of order and restoration of it in the end. In his comedies, those of external orders are explored and in his histories those of political orders are pursued. And in his tragedies, which are supposed to attract his keenest interest and deal with the problems of good and evil, he explored the destruction and restoration of moral order with greater efforts than those of external orders. But when a more careful investigation can find the intention of the author and the more internal signifcance in his tragedies. He has much more interest in the moral orders of the characters, when they confront the critical problems. In his tragedies, when the characters, good or evil, are doomed to death, a kind of poetic justics is not proved in fact, but there must be an ultimate power or order in the tragic world, which is the power or order to set everything right in the end. The statement that the ultimate power or order is moral means that it does not show itself indifferent to good and evil, or equally favorable or unfavorable to both, but shows itself akin to good and alien from evil. This dissertation explores the causes of the hero's fall: the author's concerns of moral order in othello. In this play, an initial motive of the hero's tragic failure lies in his deceptive deed of seducing Desdemona. This play shows the process of temptation into which Iago attempts to beguile Othello. Othello is, at first, large, open-minded and well-balanced, but poisoned by envy of cunning Iago, he becomes quite an another man ; chaos comes to his mind. The shock that strikes his soul when he hears of Desdemona's unchastity, makes him emotionally blind. In this play the change of the hero's moral order is more emphasized than the external order of his home or the city. Iago, embodiment of evil, for a while, seems to defeat good Othello and Desdemona, but he is doomed himself to be tortured to death in the end.

본 논문은 무선통신용 휴대 단말기를 설계하는데 있어 인체 전자파 흡수율(SAR)을 저감시키는-방법을 제안하고 있다. 휴대 단말기의 안테나로부터 방사되는 전자파에너지는 안테나 뿐 아니라 휴대 단말기 기구의 특정부분에 밀집되는데 이와 같은 표면 전계강도는 인체 두부에 영향을 미쳐 SAR값의 증가 요소로 작용한다. 따라서 이를 감소시키는 방법으로는 표면전계가 밀집되지 않도록 기구를 설계할 필요가 있으며, 이에 대한 설계 방안을 제시한다. 인체를 포함한 단말기의 해석은 유한요소법(FEM)을 사용하였으며, 본 저감법를 적용한 경우 SAR첨두치의 약 $50\;\%$를 저감하는 효과가 나타났다. In this paper, we propose SAR(Specific absorption rate) reduction methods based on surface electric field distribution relation for mobile handsets. Proposed the new method that is able to consider improvement of the SAR from the very beginning step of developing the mobile handsets. Analysis of mobile handset with human body(head) using finite element method(FEM). Results of this method, SAR reduced about $50\;\%$.

웨이브렛 영역에서 VQ 인덱스들의 상관도를 이용한 영상 압축기법
황재호 한국통신학회 2000 韓國通信學會論文誌 Vol.25 No.9
In this paper an image coding scheme using the correlation of neighboring VQ indices in wavelet domain is proposed. The codewords in each sub-codebook are reordered in ascending order according to their energy in order to inmcrease the dependency of the indices. And the relative dresses of the reordered indices are transmitted to a receiver instead of to absolute addresses. LBG algorithm is used for obtaining a multiresolution codebool and PNN using k-d tress used for generating its initial values. Our experimental results show that the proposed coding scheme outperforms JPEG and an ordinary wavelet-VQ method at low-bit rates in terms of PSNR.
인덱스 테이블을 이용한 고속 VQ 코드북 탐색 알고리즘

본 논문에서는 Wavelet/VQ 코딩 기법에 효율적인 두 가지의 고속 VQ 코드북 탐색 알고리즘을 제안한다. 웨이브렛 계수 블록 내에서 코드북의 코드워드들의 원소, 즉 웨이브렛 계수가 큰 값을 가질 확률이 적다. 이러한 특성을 코드북 탐색에 이용하기 위하여 각 서브밴드에서 코드워드의 에너지 크기로 재정렬된 인덱스 테이블을 이용한다. 코드북 탐색 시 인덱스 테이블을 이용하여 코드워드의 큰 계수 값과 그에 대응하는 입력벡터의 원소를 먼저 비교함으로써 PDE의 탈출 조건을 조기에 만족하게 되어 탐색 시간이 줄어들게 된다. In this paper, we propose two fast VQ coclebook search algorithms efficient to the Wavelet/ VQ coding schemes. It is well known that the probability having large values in wavelet coefficient blocks is very low. In order to apply this property to codebook search, the index tables of the reordered codebook in each wavelet subband ae used. The exil condition in PDE can be satisfied in an earlystage by comparing the large coefficients of the codeword with their corresponding elements of input vector using the index tbles. As a result, search time can be reduced.

The paper deals with the improvement of bandwidth characteristic of antenna for VHF mobile handset. In the general case, 1/4λ monopole and helical antenna are used for VHF mobile handset. However, various characteristics of antenna have different result for effect of hand. Especially, radiation efficient is reduced about several dB. In this paper, dual sleeve is applied to the design of broad band VHF antenna. The proposed sleeve is composed inner sleeve with slot and outer cylinder sleeve. The measurement result shows that stability of center frequency and bandwidth. In addition, the results can be applied to the design of various VHF antennas.

In this paper, a wavelet image coding scheme exploiting the correlation of neighboring VQ indices in eh wavelet domain is proposed. the codewords in each sub-codebook are re-ordered in terms of their energies in order to increase the correlation of he indices. Then, the generated indices after VQ can be further encoded by non-adaptive DPCM/Huffman method. LBG algorithm and a fast-PNN algorithm using k-d trees are used for generating a multiresolution codebook. Experimental results show that or scheme outperforms the ordinary wavelet VQ and JPEG at low bit rates.
