To position precision machines accurately, linear motion (LM) guides having rolling elements can be used. For ultra-accurate positioning control of the precision machines, the understanding of the dynamic behavior of the LM guide at the macro and/or micro scales is most critical, but the research on this subject is rare. The objective of the present research is to observe the vibration phenomena of the LM guide. Bails are used as the rolling elements in this work. Several experiments show the nonlinear characteristics of the LM guide such as hysteresis behavior and force-dependent natural frequencies phenomena.

In this paper, the prototype of a walking guide robot with tactile display is introduced, and the psychophysical experiment of the tactile recognition for a tactile display is carried out and analyzed. The objective of this research is the development of a walking guide robot for the blind to walk safely. A walking guide robot consists of a guide vehicle and a tactile display device. A guide vehicle, located in the front of the walking blind, detects the obstacle using ultrasonic sensors and offers the information of position and walking direction acquired from GPS module to the walking blind by voice. The tactile display device, located in the handle which is connected with the guide vehicle by cane, offers the processed obstacle information such as position, size, moving, shape of obstacle and safe path, etc. The psychophysical experiments for the threshold of perception and recognition ability of tactile stimulation are carried out by the estimation of the subject group. As a result the appropriate tactile stimulus intensity and frequency to recognize tactile stimulation effectively are discussed and derived.

This study attempted at first to find out a more suitable form of catalog to guide library users who need subject approach through a literature survey, secondly to see how and which catalog form is kept by Korean research or special libraries through an analysing questionnaires, and thirdly to evaluate these data and explore the ways to improve the function of classified catalog in Korean research or special libraries. The findings of this study shows that a classified catalog is more desirable form of catalog in research or special libraries in Korea because of the diversity of languages of the literatures needed by researchers, the educational programs for librarians and the problems of subject heading lists. Above mentioned questionnaire survey shows that more than $70\%$ of research or special libraries in Korea uses classified catalogs. However, among those libraries - only $8\%$ has the index of cassified catalog which is prerequisite for the catalog users. This survey also indicates that recently many libraries began or converted classified catalogs to subject catalogs. The writer explains the beginnings or convertings of classified catalog to subject catalog is due to the fact that many libraries do not have the index of a classified catalog which is badly needed by the library users. Based on these findings, writer said that to improve the function of the present classified catalog, it should include it's index to guide the library users who are not familier with the classifing system of the subjects. Through the entire paper, the writer has attempted to develop a point of argument by comparing a classified catalog with a subject catalog. Writer's point is not only a subject catalog using the particular language terms as a communication tool has problems in itself, but also the prevailing of this catalog form in North America is caused by their different situations from ours.

Making of agreement with participation subjects is important process laying stress on presentation and a reasonable design guide line to form space order grant and synthetic space in Housing Complex plan. This study analyzed residing application specific character of design guide line that is presented to architects in general planning laying stress on plan only of 'Bongmu-dong town house' and design agreement of by architectural result that appear analyze. Result that analyze is as following: 1) Confer in 18 plan contents and integrate design or was adjusted. Being main conduct and unit plan and residing only in plan many negotiations accomplish. Architect who confer most Designs of 5 architects is 'Jean Michel Wilmott' and 'Shigeru Ban' 2) contents that confer much in plan main conduct and unit generation were details plan. Contents that is conferred with many architects are about door/core/rooftop be and asked a question about proper size of entrance. Negotiation about size was expose to the tribe of knowledge about element that do furniture and detail of necessary each space in life style of our country. We must present furnitures or detail element that appear by emotion of our country and detailed item of furnitures' size etc.. in guide line. It is immediate that creation of guide that architects can approach easily for lacking abroad architects of interests by code difference in each country is pressing. 3) In residing plan 4 architects of 5 architects applied similarly guide line in design. Most architects look by active support that make synthetic housing complex. and this is construed that act positively to make by unified residing. That plan of woods or landscape architecture and security of green area space are thing to approach on 'Environment-friendly mode of life residing only' that is general planning subject of 'Bongmu-dong town house'. 4) common question items of architects guide line of though is refered definitely when make out effective interests plan. So that can overcome legislation difference, countermeasure to make understood construction code of our country is pressing

In this study, a computerized nutritional and health guide program for workers was developed. The dietitian at the work site could utilize periodically conducted medical examination data to develop an effective health care counseling model based on the developed Nutritional and Health Guide Program. A personal computer (Pentium II PC MMX-150, 32MB RAM, 2.95 GB HDD) with Microsoft Visual Basic 6.0 Enterprise Edition and Microsoft Access 97 installed, was used. The Nutritional and Health Guide Program consisted of seven main menus and 43 sub-menus. Included in the main menu were Basic Information, Periodic Health Check-ups, Visitors' Consultations, Nutritional/Health Tips, Nutritional Education according to Diseases, Help and Exit. In the Periodic Health Check-up menu, dieticians could input the health examination data of employees and touch for the recommended treatments for diseases such as obesity, diabetes, high cholesterol, hypertension and hepatitis. The Visitors'Consultation menu has been designed to compile health information about the employees who sought consultations. The Nutritional/Health Tips menu was designed to provide 14 kinds of programmed nutritional educational media and information. In the Nutritional Education According to Diseases menu, the dietitian could judge the subject's willingness to obtain treatment based on the Stage of Change Model. According, the content of the administered respective nutritional education was classified by stages. The Help menu, provide a chart of the method and procedure used as nutritional guidelines, by which the results of the health examination were classified as people in good health and those requiring special medical attention. The results of the evaluation of this program showed highly positive rates for usefulness (4.09), convenience (4.04), lettering size (4.02), interest (3.93), design (3.49). It also showed that 97.5% of the subjects thought that this program would be helpful for implementation of their company's nutritional educational program. Therefore, this menu could help dietitians plan, conduct, and evaluate their nutritional guidelines for employees. It is expected that The Nutritional and Health Guide Program developed in this study will play a role as a scientific and effective guide in conjunction with health examination results.
