Educational changes of library and information science (L & IS) at Keio university in Japan, standard of L & IS established by Japanese university educational committee, and trend of library science education in three Korean university were comparatively studied. For the efficient conduct of investigation, the art of states of L & IS was also considered. By the influence of American education, public library-oriented Japanese curriculum had changed to special library-oriented curriculum. Late 60's information science was introduced to their curriculum, library science which based upon information science theory endeavor to make its own field in a n.0, pplied science as harmonized library and information science now. Korean library science education begun with university library-oriented curriculum, accepted special library and information science at almost same time in late 60's. It gave rise to many problems to organized systematic library science. Consequently, it have needed to harmonize these two fields in near future, reorganize curriculum based on this harmonized knowledge and acquire the consensus about fundamental essence of library science education further.

The purposes of this study is to analyze the formative relationship between artistic eye-makeup and clothes design by focusing on the period from 2000 to 2010 and to find out the development direction of the next makeup design. This study considered formative theory to analyze the formative relationship between artistic eye-makeup and clothes design of $Marian$ $L.$ $Davis$ and $Marilyn$ $R.$ $Delong's$ theory, and analyzed the formative relationship between artistic eye-makeup and clothes design in an aspect of line and form, color and material, The results are as follows: First, the shapes of the artistic eye-makeup such as tear drops, and rectangular paisleys were similar with the form of clothes such as the hourglass, cylinders and mix-types. Second, monotonic color coordination mainly appeared and sometimes contrast color coordination that induced complex contrast coordination were apparent as well. Third, the objects of the artistic eye-makeup such as glitter papers, spangles and beads had similar features as the material of clothes such as silk and spangle, and contrast was partially used like colors. The results suggest that artistic eye-makeup and clothes have an organic relationship, and artistic eye-makeup is changed with formative elements of clothes.

This paper presents a semi-analytical solution for the creep analysis and life assessment of 304L austenitic stainless steel thick truncated conical shells using multilayered method based on the first order shear deformation theory (FSDT). The cone is subjected to the non-uniform internal pressure and temperature gradient. Damages are obtained in thick truncated conical shell using Robinson's linear life fraction damage rule, and time to rupture and remaining life assessment is determined by Larson-Miller Parameter (LMP). The creep response of the material is described by Norton's law. In the multilayer method, the truncated cone is divided into n homogeneous disks, and n sets of differential equations with constant coefficients. This set of equations is solved analytically by applying boundary and continuity conditions between the layers. The results obtained analytically have been compared with the numerical results of the finite element method. The results show that the multilayered method based on FSDT has an acceptable amount of accuracy when one wants to obtain radial displacement, radial, circumferential and shear stresses. It is shown that non-uniform pressure has significant influences on the creep damages and remaining life of the truncated cone.

Refractive index and speeds of sound for the binary mixture of isomer of butanol (1) + cyclohexane, benzene and toluene (2) were measured at 308.15 K. The measured data were used to calculate deviation in refractive index ${\Delta}n$, ultrasonic speed ${\Delta}u$, isentropic compressibility $K_s^E$, available volume $V_a$, excess intermolecular free length $L_f$ and molecular association $M_A$. All the derived properties were correlated with polynomial equation. Ultrasonic speed data were predicted using various empirical correlations like Nomoto, van Dael, impedance dependence and theoretically with Schaaff's collision factor theory (CFT). Jacobson free length theory (FLT) was used to calculate $L_f$. The measured refractive index was also correlated with various mixing rules. The deviation in refractive index Δn and ultrasonic speed ${\Delta}u$ was used to determine the intermolecular interactions.

In this paper we define a two parametric new generalized useful average code-word length $L_{\alpha}^{\beta}$(P;U) and its relationship with two parametric new generalized useful information measure $H_{\alpha}^{\beta}$(P;U) has been discussed. The lower and upper bound of $L_{\alpha}^{\beta}$(P;U), in terms of $H_{\alpha}^{\beta}$(P;U) are derived for a discrete noiseless channel. The measures defined in this communication are not only new but some well known measures are the particular cases of our proposed measures that already exist in the literature of useful information theory. The noiseless coding theorems for discrete channel proved in this paper are verified by considering Huffman and Shannon-Fano coding schemes on taking empirical data. Also we study the monotonic behavior of $H_{\alpha}^{\beta}$(P;U) with respect to parameters ${\alpha}$ and ${\beta}$. The important properties of $H_{{\alpha}}^{{\beta}}$(P;U) have also been studied.

The present work is an attempt to study the vibration analysis of the single-walled carbon nanotubes (SWCNTs) under the effect of the surface irregularity using Donnell's model. The surface irregularity represented by the parabolic form. According to Donnell's model and three-dimensional elasticity theory, a novel governing equations and its solution are derived and matched with the case of no irregularity effects. To understand the reaction of the nanotube to the irregularity effects in terms of natural frequency, the numerical calculations are done. The results obtained could provide a better representation of the vibration behavior of an irregular single-walled carbon nanotube, where the aspect ratio (L/d) and surface irregularity all have a significant impact on the natural frequency of vibrating SWCNTs. Furthermore, the findings of surface irregularity effects on vibration SWCNT can be utilized to forecast and prevent the phenomena of resonance of single-walled carbon nanotubes.

F. L. Wright was, from his early days, influenced by Japanese Culture and endeavored his original concept of orgonic orchitecture. In his 1st Golden Age, he devoted to establish an architectural concept of Organism which was proved by the theories of New Science and also had been universal in ancient Orient. Later, in his 2nd Golden Age, he tried to embody his unique concept in prairie houses and office buildings. The organic structure and spatial unit that actually applied to these works, were good examples of realization of the simplicity and continuity which he found out in Japanese culture. This paper is to study on the influence of Japanese culture on a course of Wright's embodying his organic architecture, and to study on a way of its realization in his works. To be concrete, main contents of the study are as follows; 1) the relationship between Wright's integrate perception and the orientalism 2) the influence of the traditional Japanese painting like woodblock prints and the aesthetic theory of the traditional Japanese pictorial art on Wright's design principles 3) the influence of Wright's experiences in Japan on his design principles 4) the influence of Wright's analysis of the traditional Japanese dwelling on his design principles 5) the course of Wright's embodying his organic architecture concept, and the way of its realization in his works.

Chua's circuit is a simple electronic network which exhibits a variety of bifurcation and attractors. The circuit consists of two capacitors, an inductor, a linear resistor, and a nonlinear resistor. In this paper, a transmitter and a receiver using two identical Chua's circuits are proposed and synchronizations of a power line are investigated. Since the synchronization of the power line system is impossible by coupled synchronization, theory having both the drive-response and the coupled synchronization is proposed. As a result, the chaos synchronization has delay characteristics in the power line transmission system caused by the line parameters L and C.

본 연구에서는 난방설비 제어에 필요한 난방부하를 건물 특성계수를 사용하여 예측하는 방법을 제안하였고, 난방부하에 주된 영향을 미치는 시간별 온도와 일사량을 예측하는 방법을 제안하였다. 온도와 일사량은 기상청에서 예보되는 정보로부터 퍼지이론을 이용하여 예측하였고, 난방부하 예측을 위한 건물 특성계수는 EnergyPlus로부터 도출하였다. 본 연구에서 제안된 방법으로 얻어진 난방부하는 EnergyPlus의 결과와 잘 일치하였으며, 예측된 온도와 일사를 이용하여 예측한 난방부하의 변화 양상은 실측 기상데이터를 사용한 결과와 유사하였다.
