In college or university libraries, the data of dissertations is one of the important academic information data. But traditional cataloging rules of dissertations and the method of operation is not only didn't unify but also fit to actual circumstances of library. This reason make librarians waste of time and the situation about piling up of unprocessed data don't make library services properly. In this papers, to analyze the above mentioned problems, I have investigated with questionaries about actual examples of construction methods of call number and item describing form of dissertations which is being used now in every college library in Korea. With the replied 61 questionaries which was compared with and investigated to merits and faults about library itself, I have showed revision ways. The characteristics of the revision ways are the followings. 1) Deleted informal and unmeaning descriptions and simplified describing. 2) Recommended to operating one or two kinds describing items which are only necessary. 3) Made call number specifically and then it make us easy to identify data and simultaneously call number can do its original action. 4) shelving range of data is made to colleges, years, departments, majors but in same departments, author's name is recommended by Korean alphabetical ordering. Besides, for proper and systematic management and operating of data. It must be necessary to recommend that reading systems of closed shelves type, incoming and outgoing and shelving by fulltime exclusive charged librarian, separate management of items and data are recommended.

In continental margins, turbid underflows which are not confined to a given channel, are free to spread laterally as well as longitudinally. Lateral spreading can reduce substantially the run out distance of flows along continental shelves and slopes. Laboratory experiments with a large tank, employing saline density currents as surrogates for fine-grained turbidity flow, coupled with dimensional analysis, have been used to develop a simple expression for lateral spreading rates of two-dimensional flows on sloping beds. characteristic length and time are determined by the flow discharge and buoyancy flux at the inlet. By knowing the initial width of the flow, the spreading law can be used to estimate the maximum width of the current at different times as well as the longitudinal spreading rate. Predictions for flows compare favorably against observations.

This study concerns with the reasons of the revision of the classification scheme and the kinds and methods of the reclassification. The reclassification IS to be implemented in case that classification numbers are wrongly given, or the scheme is revised, or it is wanted that presently using scheme should be changed to a different one. In the case of a revised edition, it is desired that reclassification is made based on the new edition because of the modernization of a data organization. However, in case of that it is not possible for the situations in the library such as the number of collections, staffs, facilities, budget, etc., the old edition can be based and the new one can be referred to. In this case, however, classification numbers may be dualized on one subject, and therefore, library must prepare the reference cards and the marks of the shelves for the different class numbers. Also, because much budget is required when the scheme is changed to another one due to its unsatisfactory usage, it should be carefully considered whether to change or not. The required time in reclassification for the relocated classification number of the revised edition is 18 minutes 54 seconds per volume, and its cost requires W 1,224.

We propose a novel programmable miniature vision module based on a custom designed analog VLSI (aVLSI) chip. The vision module consists of the optical flow vision sensor embedded with commercial off-the-shelves digital hardware; in our case is the Intel XScale PXA270 processor enforced with a programmable gate array device. The aVLSI sensor provides gray-scale imager data as well as smooth optical flow estimates, thus each pixel gives a triplet of information that can be continuously read out as three independent images. The particular computational architecture of the custom designed sensor, which is fully parallel and also analog, allows for efficient real-time estimations of the smooth optical flow. The Intel XScale PXA270 controls the sensor read-out and furthermore allows, together with the programmable gate array, for additional higher level processing of the intensity image and optical flow data. It also provides the necessary standard interface such that the module can be easily programmed and integrated into different vision systems, or even form a complete stand-alone vision system itself. The low power consumption, small size and flexible interface of the proposed vision module suggests that it could be particularly well suited as a vision system in an autonomous robotics platform and especially well suited for educational projects in the robotic sciences.

This study was aiming to examine work time, frequency, work environment, and postures of retail grocery store workers to evaluate the risk of musculoskeletal disorders. An ergonomic evaluation was conducted using job analysis and posture analysis. The four most time-consuming tasks were inspecting (27.4%), arranging (21.4%), cutting (17.6%), and displaying (15.6%). The height and length of the shelves evaluated in the field was inappropriate for workers. The most common posture was a standing posture with neutral back, and bent head, right upper arm, lower arms, and hands. Finally, this paper concluded that 'arranging,' 'cutting,' and 'displaying' seemed more stressful than other operations. The result of the ergonomic evaluation would contribute to design a better workspace in ergonomics.

This study is to establish the dwelling principle and architectural characteristics of Powhatan Indian Community in Eastern part of North America. To find a pattern and dwelling principle of town building and housing, I have researched both site survey of Powhatan at Jamestown Settlement in Virginia and a related references of North America Indian. In addition of study, I have tried to understand their life style in 17C, a spatial characteristics of space composition, and a using materials of Yehakin which means Powhatan's house in the exhibition hall of Jamestown Settlement. The results of this paper are as follows: First, the form of Powhatan house is like a longhouse which has two types that are oblong and rectangular house. Usually they had lived in the style of oblong house. Second, there are three patterns to set up the semi-permanent settlement of Powhatan, which are circle-type, street-type, and free-type of village. Third, the fire place of interior space that is most importance element to heat and cook is put it into the center of room, and the other beds and shelves are arranged by the side of wall which is covered of rush matt.

The subject specialization room will be able to support university library users who are inclined to use the general reading room. This study is the research of the area planning for university library's subject specialization room. For the evaluation, 431 users from 15 university libraries in 14 universities located across Seoul were surveyed. Statistical analysis was performed using SPSS. Frequency, percentage, mean, t-test, f-test were used. Results of the study are as follow. Subject specialization rooms in university libraries can be classified via the analysis of spatial characteristics. According to the area ratio of data space and reading space in a subject specialization room, the subject room can be separated into data-loaning and data-reading types. Old libraries are more likely to be data-loaning types, where reading room is small and there are a lot of bookshelves. The annual increase in library collections causes space for bookshelves to decrease. As a result, space for reading has been gradually transformed into space for stacking data. It is necessary to introduce ways to maintain enough space for both reading and stacking data. One way includes movable compact shelving, which can partially replace existing fixed shelves.

The transgenic technologies and their product (living modified organisms) have been developed and commercialized enough to get much attention in terms of their potentials to solve the current global difficulties such as shortage of food and energy. Furthermore, they are expected to make a big role in improving human health levels and creating bio-economy as innovative tools to pursue environmentally sound economic development. However, for the technologies and products to be developed and used in such a way that they continuously give a good impact to human society, first and foremost safety issues surrounding them should be dealt with. Every stage from in-house R&D, pilot field application to on the shelves should be managed to ensure safety following them because many consumers tend to have fear before they get the right or needed information on the modern biotechnology. In this sense, managing research facilities and LMOs for R&D from the point of safety is very crucial in that they are in the early stage of technology or product development. This paper especially deals with those to be complied with by researchers according to the Act on transboundary movement of LMOs, etc, entered into the effect from Jan. 1 2008.

The Yellow Sea is a marginal sea, surrounded by Chinese Continent and Korean Peninsula, with wide continental shelves and long coastlines. And the Yellow Sea is abundant with living resources and with coastal areas for leisure and aesthetic qualities. However, the Yellow Sea being a semi-enclosed water body, its water quality has been recently deteriorated due to rapid industrialization and urbanization of the coastal countries. Since marine pollution is transboundary, the needs for international cooperation among China, North Korea, Japan, Russia and Korea are urgent for the environmental protection of the Yellow Sea. The objectives of the present paper are to review the on-going research and to proposed the future prospects on international cooperation for the protection of water qualities of the Yellow Sea.
