Effects of the type and volume fraction of carbide-particle-reinforcements on dry sliding wear behavior of 7075 Al alloy matrix composites were investigated. SiC, TiC and B₄C reinforced 7075 Al alloy matrix composites were manufactured by a pressureless infiltration technique and wear tested. Wear tests were carried out using a pin-on-disk wear tester with varying loads of 3N-160N at a constant sliding velocity of 0.2m/s. AISI 52100 bearing steel ball was a counterpart of the composites. Wear resistance of the composites was always higher than that of the monolithic alloy except the TiC reinforced 7075 Al matrix composite. The resistance increased with the increase of volume fraction of the reinforcing particles. Among the composites, the TiC reinforced composite had the lowest wear resistance and the B4C reinforced composite showed the highest wear resistance.

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.

To ensure safety of bridge and continuously assess its condition, the maintenance system with instrumented monitoring in conjunction with visual inspection is though to be effective. By continuously monitoring the measured dynamic data under ambient vibration, it is considered to be possible to keep track of the performance change and detect any defects of the bridge. However, previous analysis procedure to decide natural frequency and dynamic parameters is time-consuming job since it involves many separate procedures by different hardware and software. In this study, a program to analyze the data measured by monitoring system is developed and it is applied to the model bridge in laboratory. The theoretical background to decide natural frequency for measured signal and the scheme to extract dynamic parameters are presented. To estimate dynamic characteristics in real time, a fast Fourier transform is introduced. To obtain reliable estimate of mode shapes effectively, an integration scheme for the measured acceleration in frequency domain is introduced and the results are verified by experiment.

Carousel systems can be classified into unidirectional and bidirectional carousel, depending on the hardware structure. Bidirectional carousels again can be classified into reversible and irreversible carousel, depending on whether the reversal of direction is allowed or not during the process of an order. In this study, single carousel served by one operator is considered. Analytical models for the rotation distance to process an order of size n are developed for unidirectional and irreversible bidirectional cases. For reversible bidirectional and Nearest Neighbor Heuristic cases, simulation results of the average rotation distance are presented. Since the throughput capacity of carousel systems also depends upon the picking time of the operator; order size; and the rotation speed of carousel, the model considers the above three factors to express the throughput capacity of single carousel systems.

Nowadays, in a company or public institutions, it is possible to grot access to various information quickly through the information highway. Since it is impossible to do that at home, a method to solve this problem is presented. By implementing Intranet for the apartment complex of at least five hundred homes, it is possible to use Internet at home. Two approaches, using modem or LAN card, were compared. It is proved that LAN card is more suitable for hight-speed Internet in implementing Apartment Intranet site in which home pages are used popularly and information is shared effectively. This paper shows that an Intranet for the apartment complex has a lot of advantages in case of utilizing various informations(local news. commercial and traffic news, education news, etc) and services(e-mail, bbs, web, etc) efficiently and promptly through this Intranet site whenever an end-user wants to get a necessary and right information. Moreover, it is possible for an end-user of apartment site to use the Intranet itself and/or related facilities much more cheaply at any time.

靑少年期 性格形成에 關한 推計學的 一硏究 : 간편 MMPI에 依한 By Simplified MMPI

申石澈 大韓神經精神醫學會 1974 신경정신의학 Vol.13 No.1

13歲에서 19歲에 이르는 男學生 1,200名을 對象으로 "간편 MMPI 性格檢査"를 實施하여 얻은 T得點을 基礎調査로 하여 因子分析法을 通한 分析結果는 아래와 같다. 1. 因子群과 各年齡에 있어서 因子負荷量의 群形成은 다음과 같다. 全對象은 {Hs, D, Hy}, {Pd, Ma} 및 {Pa, Sc} 等의 因子群으로 大別할수 있으나 ①13歲 : {Hs, D, Hy}, {Pd, Pt, Ma}, 및 {Pa, Sc} ②15歲 : {D, Hy, Pt}, {Hs, Pd} 및 {Pa, Sc, Ma} ③17歲 : {Hs, Hy}, {Pa, Sc}, {Pd, Ma} 및 {D, Pt} ④19歲 : {Hs, D, Hy}, {Pd, Pt, Ma}, 및 {Pa, Sc} 等의 群을 形成하였다. 2. 神經症尺度의 因子群은 年少群에서는 不分明하였으나 年上群에서는 分明한 因子群을 形成한 것으로 보아 神經症의 潛在 病後는 年齡의 增加에 따라 漸次的으로 形成되어 간다. 精神病尺度의 因子群은 年少群에서 分明하였으나 年上群에서 分離되었다. 3. Boaderline Profile Pattern의 數는 年上群에서 많고 因子分析에서 群을 形成하였던 因子들은 Profile pattern 形成에도 共히 參與하였다. 精神病尺度와 行動障碍尺度의 得點은 年少群에서 높았다. 尺度間 相關關係는 큰 傾向이 있었다. In studying the personality structure in total aspect, one has to examine not only the behavioral pattern of that individual, but also the dynamic potential that has induced that particular behavior. MMPI has been utilized quite effectively in the field of psychiatric as well as psychological practice for the understanding of Personality, however, it lacks in giving the information about the dynamic potential of the personality. The author has attempted to study the internal structure of MMPI by applying the factor analysis. One thousand and two hundred normal, male student, aged between 13 through 19 were selected randomly for this study. Summaries are made as follows: 1. Throughout the entire age group, the general tendency to form the group of factor loads is as follows: {Hs, D, Hy} {Pd, Ma} and {Pa, Sc}. And factor loads having shown the strong tendency to form the specific group according to the age are as follows: 1) Age 13 group: {Hs, D, Hy}, {Pd, Pt, Ma} and {Pa, Sc} 2) Age 15 group: {D, Hy, Pt}, {Hs, D} and {Pa, Sc, Ma} 3) Age 17 group: {Hs, Hy}, {Pa, Sc}, {Pd, Ma} and {D, Pt} 4) Age 19 group: {Hs, D, Hy}, {Pd, Pa, Ma} and {Pt, Sc} 2. Grouping tendency in neurotic factors(Hs, D, Hy) becomes quite distinctive as the age gets older, while that of psychotic factors(Pa, Sc) shows the reverse, ie distinctive at younger age and loose at the elder. 3. The number of boarderline profile pattern tends to increase by aging and those factors participated in forming the group at the internal structure of MMPI are also found in the formation of the same profile pattern. 4. The correlation among the various scales are very high.
