Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. But using several media may cause users' confusion and poorly designed user interface often aggravate the situation. Hypermedia systems allow the retrieval and representation of multimedia information using navigation and browsing mechanisms. Typically, there are two major navigation problems in a hypermedia compared to the ordinary user interface: disorientation and cognitive overload. In this study, the multimedia system was studied from the viewpoint of usability. Practical usability evaluation needs cost-effective, low-skill, and low- investment methods. The 'discount usability engineering' method, one of these methods, is based on the use of the following techniques: scenarios, simplified thinking aloud, and heuristic evaluation. The discount usability engineering method was applied to the usability evaluation of multimedia CD-ROM title.

A 5 kg, seven-month-old, female Pekingese dog was presented to Seoul National University Veterinary Medical Teaching Hospital with the history of anorexia and exercise intolerance. Muffled cardiac sound and mild abdominal pain were detected in the physical examination. In positive contrast peritoneography, contrast medium was observed in enlarged pericardial sac through the diaphragm. According to the history taking, physical examination and contrast radiographic study, the dog was diagnaosed congenital peritoneopericardial diaphragmatic hernia. Following midline celiotomy, herniated falciform ligament and greater omentum were repositioned to abdrminal cavity. The diaphragmatic defect was closed with absorbable suture. Clinical signs related to peritoneopericardial hernia disappeared immediately after surgical treatment. There had been no evidence of recurrence of the peritoneopericardial hernia for 1 year.

Following thesis is about comprehensive treatment of insomnia through stability of the autonomic nervous system. It is widely accepted that most of the relevant symptoms of insomnia can be blamed on successive instability of the autonomic nervous system. In order to treat insomnia effectively, it is essential to maintain stability in the autonomic nervous system. When one is at stable stage of the autonomic nervous system, one maintains steady hormonal discharge. In Oriental Medicine, it is the stage when one has a sound qi-blood circulation. To treat insomnia effectively, one has to obtain both physical and mental relaxation through various ways.

This study is to answer the following three questions: (1) What is SPICE? (2) Is it flexible enough to be applied to the small projects such as the ones owned by local companies and government agencies. The standards and models which comprise SPICE (Software Process Improvement and Capability dEtermination) or IS0/IEC 15504 were thoroughly reviewed first Based on the standards, we developed a methodology for the assessment of software processes was developed. Then the methodology is applied for the assessment for three projects in Kwangju area. For this experiment, a university, a district office, and a IT company were selected. Both the development application of the methodology was considered to be successful. As we go through the assessment, we can be convinced that the foundation of the SPICE is very sound. As we stick to the principles of SPICE, the assessment methodology that we developed worked well. The study suggests several implications for the policy making.

In this study, noise analyses were performed toward ten school and one library-building adjacent to road. In particular, noise levels measured in the case-study city were compared to those from environmental noise standard as well as to encouraged noise level. In the analyses, the following conclusions are emphasized in order to make comfortable educational learning environment. 1) When windows were open, the measured noise level of 9 schools exceeded the encouraged noise level. In order to mitigate the exceeded level, it is necessary to plant trees or lawn and install soundproofing wall. 2) When windows were closed, the measured noise level of the most schools showed lower than that of encouraged level. For sound insulation, installing both double window and casement window are required. 3) Schoolhouse's vertical arrangement from the road in order to minimize the expected noise effect, and provision of green space by which visual hiding as well as psychological comfort are presumably achieved.

The purpose of this study is to investigate material designation in library cataloging and to suggest General Material Designation (GMD) and Specific Material Designation(SMD) in Korean. A summary of the study follows. In library cataloging, methods of indicating the type of material are : (1) color-coding, (2) media code as part of the call number, (3) material designation in physical description area or note area, (4) GMD and SMD. GMD is a term indicating the broad class of material to which a bibliographic item belongs. SMD is a term indicating the special class of material to which a bibliographic item belongs. GMD was listed in parenthesis following the title proper before AACR1975 code, but currently it is listed in square brackets after the AACR1975 code. AACR2 was the standard cataloging rule in GMD and SMD terminology. It is suggested that GMD be used in Korean for graphic material, sound recordings, drawings, microform, multimedia, videorecordings, manuscripts, photographs, slides, printed music, motion pictures, printed texts, objects, braille, cartographic materials, computer files and transparenies.

In the 2nd year study of a 5 year project to evaluate the soil quality and develop the best management practices for mountaineous soils, 11 runoff plots were treated and monitored with respect to physical property of the soil, runoff and sediment discharge, and the following results were obtained. 1. Bulk density and porosity did not show any siginificant difference between experimental treatments. 2. Runoff was basically dependent on the soil's physical property and tillage. Up-and-down plots showed the highest runoff while contour plots the lowest runoff. 3. Sediment yield in the mountaineous soils was directly related to tillage and residue cover. Residue covered plots showed the lowest sediment yield and up-and-down plots the highest sediment yield. And it is recommended that the best management practices using till_age and residue cover for the mountaineous soils must be developed to protect soil quality and maintain agricultural productivity.
