This paper, coauthored by Chin-Se Chung, as well as other 5 faculty members at Hong-Ik University Department of Law (Jea-Hwang Jeong, Suk-Ho Bang, Tae-Hoon Ha, Seong-Deog Yi and Bong-Chul Choi), deals with liability issuses surrounding constitutional law, administrative law, civil law (contracts, torts), commercial law, criminal law, international law and philosophy & law. Professor of Law Jea-Hwang Jeong makes a comparative analysis of privacy protection and disclosure of information legal issues, appeared at current Korean law and draft of law in case of the latter one. He suggestes some desirable ways of legislation through revision process and operation of legal rules at his paper. Professor of Law Suk-Ho Bang makes a brief survey of civil liability issues arising out of contracts and torts in English and American law, first. He tries to show that many Parts of arguments in such legal world are attributed to Statute of Frauds tradition, unique to such legal world. New developments in the area of torts, including computer malpractice and computer virus, are shown and analysed in terms of application possibility under our current law. But, as even the Anglo-American courts are found very reluctant to accept those arguments as new grounds for torts liability, it seems more plausible and practicable to refer to contractual approach, basically, rather than to torts approach even under English American law. Professor of Law Chin-Se Chung suggests in his paper on EFT that the allocation of liability under EFT be made under the new and most relevant principle, working for useful transmission way of fund, not solely under traditional legal principles. If such new principle works with high return of risk to users, it makes imminent problems against the goats of consumer protection, and eventually will be hardly refered to. Conversely, if it requires too much sacrifice from the side of banks, then the convenience in such system will not be utilized. So, it may be natural that EFT be discarded even without proper functioning under market system. In conclusion, Professor Chung points out that, only when banks fond that the economy out of cost-saving at tasks outweighs the risk undertaken by the banks, the banks will operate the system. But, if this system makes more return of benefits to the banks with the burden of users, it is against the idea of equity. Consequently, the banks should bear the aggeviated risks in return for the cost saved under this system Professor of Law Tae-Hoon Ha focuses his research paper on criminal liability under EFT. He draws his conclusion out of current criminal statutes that illegal fund transfer under automatic teller machines, cash cards and information system can not be penalized due to lack of proper statutory provision. So, the criminal provision on computer crime, newly made on December of 1995, can be positively appreciated. But, he anticipates that the question whether such new provision will be successful in regulating all illegal activites at fund transfor system without any operation defects in criminal code, or will cause new problem in interpretation of criminal code remains unsolved. Professor of Law Seong-Deog Yi examines the international legal issues which may be given rise to by direct satellite broadcasting. In his paper, the issue of national jurisdiction in relation to direct satellite broadcasting is firstly dealt with. Secondly, the possible ways in which direct satellite broadcasting is regulated by international law are examined with special emphasis of two different approaches, that is, freedom of information approach and state sovereignty approach. In this context, many international conventions concerning direct satellite broadcasting in Particular, and international regulatory regime of outer space in general are broadly reviewed. Thirdly, the types of activities which may be a violation of international legal regime of direct satellite broadcasting are suggested and the possible lethal remedies for these violations are proposed with the traditional international state responsibility law in mind. Professor of Law Bong-Chul Choi explores the relations of computerized society to its laws throughout his paper as a kind of conclusion of this whole paper. Computerized society is one that the technical, scientific, informational knowledge prevails. With correspondence to the structural change in knowledge, the law of such a society has suffered transformation, and the knowledge and techniques distributing and computing legal responsibility has also changed. However, he does not insist that the diffusion of technical knowledge is the sole factor of the transformation of legal responsibility. It is only one of the various factors. Moreover, he does not deny the continuation between the classical techniques distributing legal responsibility and the contemporary ones. In this era, the law realizes fairness and community values at the expense of singularities. In addition, he proposes that legal scholars take the diagnosis of law from the perspective of the technology/knowledge shifts seriously.

정정수(Jung-Soo Chung),김영식(Young-Sik Kim),장지웅(Ji-Woong Jang),노종선(Jong-Seon No),정하봉(Ha-Bong Chung) 한국통신학회 2008 韓國通信學會論文誌 Vol.33 No.11C

[1]에서 LCZ 수열군의 2배 확장을 제안하였다. 본 논문에서는 [1]에서의 2배 확장방법을 일반화하는 새로운 확장방법을 제안한다. 이 생성방법을 사용하면 인수가 (N,M,L,ε)인 q진 LCZ 수열군은 인수가(pN,pM,p「(L+1)/p」-,pε)인 q진 LCZ 수열군이 된다. 이 때, p는 소수이고 p는 q의 약수다. 특히 L≡p-1modp 일 때, 확장된 q진 LCZ 수열군의 인수는 (pN,pM,L,pε)이 된다. In this paper, a new extending method of q-ary low correlation zone(LCZ) sequence sets is proposed, which is a generalization of binary LCZ sequence set by Kim, Jang, No, and Chung. Using this method, q-ary LCZ sequence set with parameters (N,M,L,ε) is extended as a q-ary LCZ sequence set with parameters (pN,pM,p「(L+1)/p」-1,pε), where p is prime and p|q.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Lin Conjecture의 증명에 관한 연구

鄭夏奉 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-

Lin conjecture is one of the well-known conjectures on the existence of the ternary sequence tr^(n)_(1)(x+x^(d)), x∈GF(3^(n))\{0}, of length 3^(n)-1 with the ideal autocorrelation property. In this paper, we address the possible approaches toward the proof of the Lin conjecture. Firstly, we suggest that the sequence can be considered as an element in a subring of a Group-ring and that the proof of the Lin conjecture could be tried to show it is a difference set. The second approach we suggest is using the cross-correlation results for an m-sequence and its decimated sequence. Finally, we suggest to employing the rank notion of quadratic form in the derivation of the autocorrelation of the Lin sequence.

In this paper, we studied the cryptographical properties of Boolean functions used in the crypto system. Mainly we investigated into the problem of finding the maximum possible distance to the affine mappings of a binary vector Boolean functions. The classification of bent functions are introduced and some lower bounds on the maximum distance to the affine mappings both over the set of general vector Boolean functions and over the balanced Boolean functions are derived. We also proposed a new design of set of Boolean functions with the best nonlinearity known. Though these functions do not have SAC property and correlation immunity property. we believe that this design will serve as a foundation in the future design of Boolean functions with good cryptographical properties.

Direct Methanol Fuel Cell (DMFC) is based on the technology of Polymer Electrolyte Membrane Fuel Cell. DMFC has several features of environmentally benign generation of electricity and high mobility for portable electronics etc., but its main problem to overcome for commercialization is the high cost of noble metal catalysts. In this study, it was found that the Pt/C catalyst supported on carbon nano fiber had the highest catalytic activity among the catalysts supported on several carbons. The newly developed Pt/C alternative catalyst had higher catalytic activity for methanol oxidation than the Pt/C catalyst supported on Vulcan XC-72.

On the Premitive Cyclic Codes with Minimum Distance 5

Chung, Ha-Bong,No, Jong-Seon Research Institute for Science & Technology, Hong- 2001 Hongik Journal of Science and Technology Vol.5 No.-

In this paper, we investigated into the minimum distance of a primitive binary cyclic code C with a generator polynomial g(x) = m₁(x)and m_(d)(x) . In our derivation, the necessary and sufficient condition for C to have minimum distance 5 is the fact that x^(d) is an APN power function.

In the analysis of trace codes,it has been a meaningful task to evaluate the Hamming weights of the codewords repesented by trace functions. The most wellknown technique in the computation of Hamming weights of such codewords is so called 'Exponential Sum' technique, and in this technique we have to find out the roots of specific linearized polynomials. In this paper. we investigate into the Hamming weights of given codewords in the dual codes of binary triple-error correcting BCH cods using exponential sum technique and enumerate the number of roots of the linearized polynominal, z? + b⁴z? + b²z²+ z, in the same field to which the coefficients of the polynominal belong.
