The purpose of this study is to investigate the character and costume of the long-guan clay figures that were excavated in Bu-yeo Jeong-lim Buddist temple foundation. For this, we first examine the Chinese official uniforms with long-guan, classify the types of long-guan, and then investigate the costume that is worn with long-guan. There are three types of long-guan in China, and that of the clay figures in Jeong-lim Buddist temple foundation is of type 1. Therefore, the characters of the clay figures are woman servants, and their costume is either blouse-and-trousers or blouse-and-skirt.

마이크로어레이 기술로 인해 많은 양의 유전자 발현 데이터가 생겨났다. 데이터의 양이 많아짐에 따라 이를 체계적으로 관리해야 할 필요가 생겼고 이를 위해 LIMS(Laboratory Information Management System)가 만들어졌다. LIMS는 실험 데이터를 체계적으로 관리할 뿐만 아니라 같은 실험실에 있는 연구자 간에 데이터를 공유할 수 있는 장점을 갖고 있다. 만일 여러 연구실 간에 공동연구를 한다면 데이터의 공유가 필요하게 된다. 이를 좀 더 편리하게 하기 위해 다른 연구실의 LIMS에 저장된 데이터 중에 허용된 데이터에 한해서 자신의 LIMS에서 바로 접근할 수 있도륵 하는 분산 LIMS를 소개하고자 한다.

It is necessary to modify the state-of-the-art of speed control theory because of the phase asymmetry in the Linear Induction Motor (LIM)and for the constant speed control of mover using single vector control inverter system, it is important that primary stack is located in appropriated intervals in the 3D conveyer system using LIM. The dynamic characteristic analysis method of the vector controlled LIM using coupled FEM and control algorithm taking into account the movement is proposed. The focus of this paper is the analysis relative to selecting primary stack intervals in order to constant speed control in the 3D conveyer system using LIM.

LIM has been developed for use in the industry, transportation, OA, FA because of the merits of direct drive and simple structure. The thrust control of LIM usually has been the average thrust control. However, vector control is required to control the instantaneous thrust force for an accurate positioning and speed control. To obtain dynamic vector control characteristics, it is important to make equivalent circuits which represent exactly LIM In this paper, asymmetrical d-q equivalent circuits is built [1] and vector control characteristics is calculated by simulation using these circuits.

Because most LIM is driven by inverter, input voltage is involved with the time harmonics. Therefore the equiLlQ/ent circuit for an inverter-fed LIM has to be modified to represent every harmonics present in supply voltage. This paper analyzes the characteristics and loss of LIM to construct the equivalent circuit for each time harmonics through the static test and theoretical analysis. To make an analysis of nonsinusoidal supply waveforms, it is developed the simulation program to calculate the RMS, peak value and THD for any waveforms expressing Fourier series.

The recent trains are almost being operated by the mechanical propulsion force to drive the gear and wheel with the traction motor. However Magnetic Levitation Vehicle is differently operated. Magnetic Levitation Vehicle is applied with Linear Induction Motor(LIM) that has many advantage like to high capability of going up to slope, low noise, easy to control of speed. So domestic and many advanced countries are interested in Magnetic Levitation Vehicle and they have been studying about it continuously. Thus this paper is studied the LIM test method of static states and guess the optimum driving point by characteristic of static states for LIM. The test items are measurement of thrust force by changed air gap, measurement of thrust force and normal force by changed slip frequency etc.

도서관리시스템에 RFID를 활용하면 도서의 대출 반납이 자동화되는 등 많은 이점이 있다. 하지만 이를 이용하더라도 도서의 정확한 위치를 파악하는 것은 어려운데, 본 연구팀은 R-LIM2의 개발을 통해 도서의 위치파악 기능을 제공한 바 있다. 본 논문에서는 색인된 도서의 위치까지 안내하여 주는 내비게이션 모듈과, 도서위치를 담고 있는 DB를 보다 손쉽게 구축할 수 있는 모듈을 개발하여 기존 R-LIM2 시스템의 기능을 향상시키고자 하였다.

We show the existence of inductive limit in the category of C^*-ternary rings. It is proved that the inductive limit of C^*-ternary rings commutes with the functor 𝓐 in the sense that if (M_n, ϕ_n) is an inductive system of C^*-ternary rings, then $\lim_{\rightarrow}$ 𝓐(M_n) = 𝓐$(\lim_{\rightarrow}\;M_{n})$. Some local properties (such as nuclearity, exactness and simplicity) of inductive limit of C^*-ternary rings have been investigated. Finally we obtain $\lim_{\rightarrow}\;M_{n}^{**}$ = $(\lim_{\rightarrow}\;M_{n})^{**}$.
