The purpose of this study is to review the historical development of British Museum Library and its cataloging rules which really marked the beginning of the modern era of cataloguing. The results of the study can be summarized as follows (1) Sir Anthony Panizzi was the most creative force in the history of the British Museum Library. He devoted himself to the formation of the British Museum Library cataloging policy and the compilation of printed catalogues. Moreover, he laid down the sound acquisitions policy and the vigorous a n.0, pplication of the copyright deposit privilege. He designed a great circular reading room and raised standards of library service and administration. (2) British Museum Library Cataloging Rules : 1. are notable for their pioneering efforts-this was the first major catalogue code-and for their influence on all subsequent codes. 2. introduced the concept of corporate authorship but has never dealt with problem very satisfactory. 3. went to great lengths to avoid title entry. 4. used a number of form heading, example for, ACADEMIES, PERIODICAL PUBLICATION, EPHEMERIDES, CATALOGUES etc.

This paper describes the energy absorption of a square tube under axi compression by using the finite element method. The overall deformations and lo buckling modes of tube was discussed by "plastic hinge concep Force-displacement function was plotted to show various state that depended or time. Also, mean crush load was expressed as a type of section geometry a material property using dimensional analysis. To verify the energy absorption and the effects of dimensions, The standards Wt used as related density and specific energy, mean crushing load and the resL were discussed by the relation between crush load and deformation, the relati between related density and specific energy, the relation between crush load a mean crush load, the relation between mean crush load and specific energy.ergy.

This study begins with investigation of the purpose and background of the International convention on Standards of Training, Sertification and Watchkeeping for seafarers 1978, London(STCW) which will be put into force on and after 28th April 1984. Author tried to confirm those common points on requirement of the qualifications between the radio officer regulated it. the STCW Convention and radio communications between the radio officer regulated in the STCW convention and radio communication operator's general certificate in the Radio Regulations annexed to the International Telecommunication convention. Then, Japanese communications administration is taken as a model for the comparative analysis, as Japan and Korea have many resembling aspects, especially legal and social aspects. Therefore, as one of urgent tasks of Korean Communications Administration preparing for the STCW convention, Istressed on partial amendment of the Korean Radio Regulatory Act.

In this outline, the stability of solid/liquid dispersion was theoretically investigated the matter from all angles by using the modified DLVO theory. The stability was handled various considerations such as a production and characteristics of electrical double layer, total interaction$(V_T)$ that consisting of attractive force$(V_A)$ and repulsion$(V_R)$. coagulation, the stability ratio(W), critical flocculation concentration (cfc) and zeta potential$(\zeta)$ etc. It was possible for us to examine with the stability ratio(W), critical flocculation concentration (cfc) and zeta potential$(\zeta)$ that may estimation of stability of solid/liquid dispersion experimentally.

By no means rapid advances in technology affects the working and improvement of all systems built to increase the quality/standards of human living. Information technologies as the main driving force of technological progress today happen to be a sine qua non for all organizations hoping to keep pace with or surpass rivals. However, despite their vital advantages it is true that these create undesirable side effects that harm social systems and the rights of persons. Similar to all others in the world Turkey is trying to cope with the problem through creating an appropriate legal and administrative substructure trusted to discontinue or at least minimize such criminal acts.

For each strand of wirerope sling, the international standards, ISO-8794, EN-13414 specify that the splice shall have five series of load carrying tucks. At least three of the load carrying tucks shall be made with the whole strand. And, the breaking force of the splice shall not be less than 70% or 80% of that of rope. But, There are no prescriptions for splicing types against different efficiency of each splicing type being used many workplace. In this study, analysis the work limit load efficiency according to variation of number of tucks and splicing types by experimental method As a result, the number of tucks 3+2 had the highest breaking efficiency.

The use of Switching elements in power systems causes the current or voltage to involve harmonic waves. Harmonics bring about registration errors of the equipment for measuring power. In case the induction watthour meter designed on sinusoidal source is used in the measurement of power with harmonics, the precise measurement of power has many problems because harmonics cause a decrease of power factor and vibration by the unstable driving force on the aluminum disc. In this paper, analysis and test results on the harmonic sensitivity of an induction watthour meter is reported when the input voltage and current with harmonics were supplied to single-phase watthour meter.

A new quaternary ammonium compound, hydrolyzed ginseng-sapoin quaternary (HGSQ), from hydrolyzed Korean ginseng-saponin and 2, 3-epoxypropyltrimethyl ammonium chloride has been developed as a conditioning agent for hair care products. This structure has the hydrophilic group from the introduced cationic and the hydrophobic group from the aglycone of ginseng saponin. Its properties: surface tension, conductivity, critical micelle concentration, eye irritation, sorption onto hair, force reduction (%) for 20% extension and moisture retention effect comparing with the commercial standards. Also half-head tests of HGSQ-containing shampoo were carried out to compare the conditioning effects in shampoos.

This paper presents the experimental results on the development length of FRP tendons by direct pullout test. Two types of FRP tendons, namely, CFCC tendon and KICT tendon, and PS tendon were investigated. The development length defined as the minimum embedment length required to develop the ultimate tensile strength was suggested using the test results. It was found that the development length from the direct pullout test was greater than those of various standards. This may result from the fact that the wedge effect does not exist because there is no prestressing force in the direct pullout test. Further study and experiment are necessary to derive the reasonable development length for FRP tendon.

Unlike concrete bridge, steel bridge resists external force by forming thin plate. Thus, because steel girder bridge has big slenderness ratio, buckling is a major design factor. Plate girder consists of flange and web plate. Because of economic views, web plate that resists shear forces is made by more thinner plate. Thus, web plate has much risk for buckling. The objective of this study is to analyze the buckling behaviors of plate girder and to present the proper reinforcement location of longitudinal stiffeners. Various parametric study according to the change of web height, transverse stiffeners and load condition are examined.
