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.

流體로 채워진 圓筒 Channel內 捧 集合體의 振動解析

鄭炅勳,李聖哲 全北大學校 1993 論文集 Vol.36 No.-

Free vibration of the tube bundle in a channel filled with stationary liquid is investigated. Added mass coefficients which are based on velocity potential theory are calculated and used to computing the natural frequencies and mode shapes of tube bundle in liquid. The natural frequencies of the tube bundle are obtained as a function of the spacing between tubes and verified by an experiment. The experimental results show good agreement with the computer predictions. As the spacing between the tubes is small, namely gap to diameter(G/D) becomes small, coupled natural frequencies are widely distributed. A wide spacing tube bundle goes the results of single tube in an infinite liquid.

Various surgical approaches to the orbits have been used. But the transconjunctival approach, also called the inferior fornix incision, provides adequate access to the orbital floor with esthetic results. Additionally, transconjunctival approach with lateral canthotomy allows more wide surgical field and good access to the orbital area. Generally, preseptal approach is more used rather than postseptal approach in the transconjunctival incision for the prevention of fat herniation during surgery. There are some complications in transconjunctival approaches but these complications can be prevented with careful surgical techniques. We report clinical results in 12 patients who were treated by preseptal transconjunctival incision with lateral canthotomoy for the treatment of orbital trauma. We were satisfied with this technique for reduction and reconstruction of the orbital trauma and we could also observe relatively good esthetic results.

Sn-xAg-0.5Cu 무연 솔더 볼의 파단특성 연구

This paper presents a study on the failure characteristics of SnAgCu lead-free solder balls. To estimate the effect of Ag, three types of SnAgCu balls are first prepared by varying the weight percent of Ag (1.0, 3.0, 4.0 wt%) and then analyzed by reliability tests such as thermal shock, high speed ball shear, and drop tests. Thermal shock test reveals that the higher the weight percent of Ag is, the longer the fatigue life becomes. To the contrary, high speed ball-shear test and drop test show that the shear strength and the fracture toughness of solder balls are inversely proportional to the weight percent of Ag, respectively. Reasons for these observations will be further investigated in the future work.

This study aims to estimate strength approximate to actual concrete strength by presenting appropriate rebound method strength estimation expression with admixtures (fly ash, blast furnace slag, silica fume) which are used as cement substitute and polypropylene fiber and steel fiber and owing to their s of cement owing to their equal conditions to blending characteristics of concrete used for domestic structures and their recyclable properties. In case of rebound hammering, equation by Japanese Architecture Society was estimated 26~40% higher than destructive strength and remaining suggested equation was estimated 2%~18% lower. In case of ultrasound velocity, equation by Japanese Architecture Society was estimated 4%~11% higher than destructive strength till 60 days of age, but as age progresses, is estimated to 15% lower than destructive strength and remaining suggested equation was estimated 3%~27% lower than destructive strength in almost age. In case of complex methods, all suggested equations were estimated to 24%~94% higher than destructive strength. Since application of existing expression of normal concrete against concrete using admixtures and fiber causes error rate, this study suggests the following estimation expression depending on the kind of admixtures and fiber of concrete using them and position of non-destructive experiment. C-N f_(cu)=1.6R-25.43(R²=0.90), C-FA f_(cu) = 1.07R-8.76 (R²=0.82), C-BF f_(cu)=1.46R-23.09(R²=0.92) C-SF f_(cu) = 1.55R-22.96(R²=0.89), C-PP f_(cu) = 1.16R-12.24(R²=0.73), C-S f_(cu)=0.99R-8.07(R²=0.86)

This study was performed to elucidate the influence on the plasma decursinol concentration after administration of combined decursin and Cnidii Rhizoma or decurisin and Bupleuri Radix extracts in comparison with single decursin admimistration. The identification of decursional isolated from Angelica gigas was carried out by GC/MS and the concentration of decursinol in the plasma after oral administration was determined by HPLC. The value of area under the plasma concentration (AUC) and the maximal concentration (Cmas) of decursinol after administration of methanol and ether Angelicae Gigantis Radix extract was higher than those of single decursin-treated group. It was also found that the AUC and the Cmax of decursional after combined administration with decursin and Cnidii Rhizoma were higher than those of decursin administration, whereas those of combined with decursin and Bupleuri Radix was lower. Moreover, the studies were performed with decursinol only or with combined decursinol and Cnidii Rhizoma/Bupleuri Radix, both of combined treatment increased the plasma decursinol concentrations compared with decursinol-treated group in rats. On the basis of these results, it is concluded that co-existing substances or co-administration with other drugs may influence the plasma levels of decurisinol after oral administration.

The purpose of this study was to investigate the level of acrylonitrile(AN) exposure in workplace air and body burden of AN as a form of hemoglobin adduct. The mean of AN concentration of 10 workplaces was 0.24ppm(GSD 4.80) which was under TLV(2ppm). But 7% of 140 measurements and 5 of 10 workplace was over TLV. The GM of hemoglobin adduct detected with cyanoethy-Ibaline(CE) in 110 biological monitoring was 1.51nmol/g globin(GSD 3.43). The correlation coefficient between AN concentration in the workplace air and the amount of hemoglobin adduct measured by CE concentration was 0.56. And the equation showed y= 2069.1 + 1861.2. If 2ppm of airborne AN TLV insert to that equation, the concentration of hemoglobin adduct detected with cyanoethlvaline is 6.0nmol/g globin and this value means biological indices(BELs) of ACGIH. 8% of workers showed over 6.00nmol/g globin. For most of workers were exposed to AN intermittently according to their special assignment of that day, ambient monitoring for a day could not effectively represent their body burden. And it was very good compensation for ambient monitoring to evaluate each worker's cumulative exposure by biological monitoring of hemoglobin adduct detected with cyanoethylbaline.
