Building materials have a great impact on the health of a building's occupants. Thus, it is imperative that their health-related properties be taken into during the course of construction project. Unfortunately, no current database system exists that can provide information on the health performance of building materials at each stage of construction project management, from planning and design to building and maintenance. therefore, an inordinate amount of time and effort is required to choose the right health-friendly materials(DBHM). To solve this problem, this study aims at building a database management system for health-friendly building materials. It analyzes the health-related properties and performance of various materials, and proposes a database structure and operation algorithm. The system proposed in this study is expected to contribute to the objective evaluation of health-friendly building materials through the accumulation of relevant data.

The contents of a new book currently in preparation are described. The dearth of books in the field of nuclear materials has left both students in nuclear materials classes and professionals in the same field without a resource for the broad fundamentals of this important sub-discipline of nuclear engineering. The new book is devoted entirely to materials problems in the core of light-water reactors, from the pressure vessel into the fuel. Key topics deal with the $UO_2$ fuel, Zircaloy cladding, stainless steel, and of course, water. The restriction to LWR materials does not mean a short monograph; the enormous quantity of experimental and theoretical work over the past 50 years on these materials presents a challenge of culling the most important features and explaining them in the simplest quantitative fashion. Moreover, LWRs will probably be the sole instrument of the return of nuclear energy in electric power production for the next decade or so. By that time, a new book will be needed.

The purpose of this paper is to provide the basic information concerning school health nursing activities in schools lacking in a school nurse, and the degree of satisfaction of trainess to the training course of school health nursing. The data for this study were collected by means of questionnaire from 150 teachers(100 of primary school and 50 of middle school)who attended the training course superintended by the Board of Education of Kyeong Nam Province from July 27 to August 6 in 1987. The main results of this study can be summarized as following; 1. General characteristics of the trainees: The majority of the trainees (71.3%) were in the age of twenties, 86.5% graduated from four-year teachers' college, 63.5% had less than five-year experience as a teacher. 2. 60.5% of the trainees were actually offering school health nursing services. 67.8% decided voluntarily to participate in the training course, and 62.7% attended the course for the purpose of obtaining health knowledge. 3. Only 4.2% of schools established appropriate health organization, and 34.5% were equipped with nursing clinic. But the main reason school health nursing activities were not performed very well was the insufficient supply of needed medicines and related materials. 4. School health nursing services in schools lacking in a school nurse were offered mainly by the teacher holding additional job of school health. class teacher and atheletic teacher. But the sanitary management for school meal services and community health activities were not carried out at all in many schools. 5. As a whole, trainees were satisfied with training program. But some subjects of the course did not satisfy them because those ones were so theoretical without any practice. 6. Many trainees wished the training course to be more concentrated on case studies which are helpful to solve actual problems. 7. 75% of trainees answered to have decided to perform school health nursing activities more actively than before. 8. Any significant relationship can not be found between trainees' general characteristics and their attitude to school health nursing activities after the training course. Only one factor-motivation to attend the training course-had the statistical significance of 8.7%.

Toughening of epoxy resins for improvement of crack resistance has been the subject of intense research interest during the last two decades. Epoxy resins are successfully toughened by blending with a suitable liquid rubber, which initially remains miscible with epoxy and undergoes a phase separation in the course of curing that leads to the formation of a two-phase microstructure, or by directly blending preformed rubbery particle. Unlike the situation for thermoplastics, physical blending is not successful for toughening epoxy resins. Recent advances in the development of various functionalized liquid rubber-based toughening agents and core-shell particles are discussed critically in this review.

An account book of medical treatment is a form of collection materials for diagnostic standardization, and it is a basis of standardization, standardization of medical records is a preconsideration of each standardization. But an account book of medical treatment is only a kind of form for recording medical treatment, therefore standardization of medical treatment eventually holds the key to the standardization of recording charts. However until now we have gradually reformed medical records in accordance with individual characters of medical treatment, and didn't have even standard sheme of medical records, also medical terms for medical records had an inconsistency of redescription and reiterative representation for an identical terms in all parts of the East learning, medical terms for medical records didn't unity. To make better this realities, standardization study used orginated system in the process of existing study, it can get ready the basis of discussion between O.M.D and O.M.D. it can make analysis of diagnostic course and can clearly understand usable information by diagnostic course. for that reason we hope that the basis of standardization is accomplished. And in advance of study for this standardization we have to analysis the course of medical treatment with demonstration of roof, first of all we have to study term definition by diagnostic course and prepare basis by diagnostic course. because this study have limits of indivisual study, it needs to long and synthetic investigation in Association levels. Although we cann't completely alternate with methods of measurement which relyed on individual mastery, if we exclude erroes of individual measurement through mechanization and verify results of diagnosis through keynotes, we can realize standardization of medical treatment with demonstration of proof and in this process we can use medical records as a tool collecting exact data, also we can realize standardization of drawing up medical records.

This research aims to obtain useful data on the development of compression garment products with high-stretch knitted materials. Using nylon SCY, four specimens were knitted. Then, appearance (width, length, weight, thickness), stretch property (stretch, recovery) and clothing pressure were measured and their interrelation was analyzed. In the comparison of appearance features, yarn floating caused shrinkage in both course and wale directions of the specimens. Yarn overlapping by tucking caused a release in the course direction and shrinkage in the wale direction. Also, structural change was affected by the weight and thickness change of the knitted fabric. In the analysis of fabric stretch, yarn floating reduced the extension in course direction and increased that in wale direction of the knitted fabric. However, yarn overlapping reduced the elongation in both directions. In the analysis of recovery, yarn floating and overlapping raised fabric recovery in both directions, and tuck structure was superior to float in recovery. In the analysis of clothing pressure, 'Plain-Float' structured fabrics showed a higher clothing pressure than 'Plain' and the clothing pressure value of 'Plain-Tuck' was lower than that of 'Plain'. As for the correlation between fabric appearance, stretch property, and clothing pressure, the appearance change in course direction had a major influence on the clothing pressure. The shrinkage of appearance led to a decrease in stretch and an increase in clothing pressure.

PURPOSES : As a research to develop a cement treated base course for an airport pavement which can enhance its drainage, this paper investigated the strength, infiltration performance and durability of the pervious concrete with respect to maximum coarse aggregate sizes and compaction methods. METHODS : This study measured compressive strength, infiltration rate, continuous porosity and freeze-thaw resistance of pervious concrete specimens, which were fabricated with five different compaction methods and different maximum aggregate sizes. In addition, in order to reduce the usage of Portland cement content and to enhance environment-friendliness, a portion of the cement was replaced with Ground Granulated Blast Furnace Slag (GGBS). RESULTS: Compressive strength requirement, 5 MPa at 7 days, was met for all applied compaction methods and aggregate sizes, except for the case of self-compaction. Infiltration rate became increased as the size of aggregate increased. The measured continuous porosities varied with the different compaction methods but the variation was not significant. When GGBS was incorporated, the strength requirement was successfully satisfied and the resistance to freezing-thawing was also superior to the required limit. CONCLUSIONS: The infiltration rate increased as the maximum size of aggregate increased but considering construct ability and supply of course aggregate, its size is recommended to be 25mm. With the suggested mix proportions, the developed pervious concrete is expected to successfully meet requirements for strength, drainage and durability for cement treated base or subbase course of an airport pavement.
