In the fields of the cultural properties, the Infrared TV camera is being initiated to use instead of the Infrared photo film fo a better means to detect the description of drawings of the paintings. Seeing from the effect of transillumination, the Infrared TV camera with its long wave of visible spectrum that makes less absorption by the pigments and with the reflection rays passing through the base of colour layers makes it able to findbase drawing and letters. The detection range of transillumination by the infrared rays depends on the kinds of pigments, lines of the base drawing and wave length of the infrared rays. In our country, it was the first time to detect by our Conservation Science Dep't of The Research Institute of Cultural Properties by means of using Infrared TV camera to determine the mural paintings on the Josadang, Busuk Temple, resulted in an epoch-making success, that we have come to know the painting technique methods, how to treat for its conservation and making replica, reproduction, etc.

In the age of knowledge and information when every aspect of economy, education and culture in society is changing rapidly, the teacher is not just a provider of knowledge in classroom. Ultra-modern educational tools and materials have come into being with the latest developments in science and technology and we see classroom teaching in general tending towards more 'open' classroom and study. What the students need most for the coming century is the cultivation of higher faculties such as creative thinking, the power to solve problems, and the spirit of inquiry. The present-day teacher is required to make use of various teaching medial in order to provide the students with better educational environment for developing these faculties, not the teaching method of the past with the teacher at the center. One way to enhance classroom environment is in reintroducing the modernized teacher's desk to the center of teaching apparatus. This paper is about the better way of designing the teacher's multimedia desk equipped with a PC that will make it possible for the teacher to utilize the internet-based educational resources.

Recently, the field of university PR(public relations) and UI(university identity) come to be emphasized as a remarkable one because the applicants to the universities are consistently reduced in Korea. The purpose of this thesis is to present a souvenir for university PR which is designed in a clothing commodity, easily accessible to visitors, helping students and university officials to keep a pride to our university. We have designed four kinds of clothing, ie T-shirts, polo-shirts, trousers, and hats, after scrutinizing those of other universities. By making change the length of sleeves and slacks, the four kinds were transformed into eight kinds of clothing commodities. The basic trend of this design is on the trompe l'oeil, with the colors being white, grey and black ones, which are of 100% cotton.

HTS wires processed by PIT method are now available for magnet applications. But, those wires can not be used over 40 K due to weak link. This leads to necessity of development of coated conductor which can retain high $J_c$ at high field in liquid nitrogen. In this paper, various technical issues and the R&D status for both PIT wires and coated conductor were discussed. The difference of coated conductor's processes were also investigated and summarized. Various requirements for a design of HTS magnets were discussed. Anisostropic $J_c$ property with respect to magnetic field was considered to determine the coil's critical current. Low n value is a critical parameter to degrade a field stability with respect to time for a persistent mode HTS magnet. The relation between the margin of operation current and n value was investigated. Prototype HTS magnets with PIT wires are being developed for various applications such as crystal growth, MRI, magnetic separator and etc. HTS magnets will come into wide use in various fields of industries if the HTS wires with a low performance cost is developed.

Fashion merchandiser profession is a highly information-intensive job. In fact, a merchandiser is to acquire a variety of information mainly from external environment and to analyze it in order to come to an informed decision. Despite a significant amount of past studies on environment scanning, their main concern was of managerial work. And, some fashion design studies have only touched the issue of information source in a descriptive tone. Here, we attempt to analyze empirically fashion merchandisers' environmental scanning activities. Our results can be stated as follows : 1) Though the quality of information source has a positive relationship with its use, the accessibility does not. 2) There is no significant difference between the use of relational source and the use of non-relational source. 3) Internet is being used more at the initial stage(opening) of information seeking than at the orientation and consolidation stage.

In order to align the shaft, the dialgauge method has used as a means of solution until now. The method using a dialgauge require a great deal of labour and money due to making by hand, the accurate alignmentis not up to the expectation. For aligning the shaft, all the rotor must come to accord. It means that the moment of the point of coupling must keep being "Zero". The ideal measurement method as to material on the zero is used by straingauge which can gauge the moment at any point of the shaft. Also, the dialgauge method cannot be compared with straingauge measurement method, form the viewpoint, which can gauge in short time.hort time.
