The purpose of this study was to analyze the contents of the sound environment among the various environmental factors that directly or indirectly affect the quality of education through the remodeling of the small hall of the College of Humanities at W University. Before remodeling into a lecture room, the small hall of the College of Humanities at W University, which is the subject of this study, was designed to create an indoor sound environment suitable for a lecture room by recognizing differences in acoustic performance between the performance halls that require adequate sound quality and the lecture rooms where the clarity of voice is important. Therefore, this study aimed to present examples of improved acoustic performance in lecture rooms by remodeling through the stages of measuring acoustic performance before remodeling, presentation of a change in finishing materials through sound simulation, and measurement of sound performance after remodeling. It is expected that this process can be used as an example of securing indoor acoustic performance suitable for educational space, such as lecture rooms, by changing the finishing materials.

A new era has come where high quality educational materials can be acquired easily through the World Wide Web. These materials, however, need to be refined and streamlined to maximize their effect on education. In order to provide such a streamlined flow, we need to be able to re-organize documents, which exist independent of each other on the Web, in a way that maintains their appropriate order in the right context to satisfy educational purposes. In addition, we should be able to provide supplementary explanations or missing information to the organized materials for smooth connections among them. In order to meet the requirements, we employed the virtual document concept that allows us to reuse existing documents for educational purposes. By providing a retrieval engine for virtual documents, we attempt to induce self-directed learning based on document retrieval, suitable for the level and purpose of students.

The purpose of this research was to develop risk communication (RC) strategy and educational web-site on food additives for elementary students and their parents to improve their perception on food additives and dietary life. First of all, a survey was conducted from 1,200 elementary children and their parents to diagnose the perception and information needs on food additives. The survey revealed that most children and their parents did not have enough knowledge on food additives and demanded the safety information on food additives. Second, previous researches on food communication were analyzed to develop a risk communication model, and it was directly applied in this study. Third, a web site (www.foodnara.go.kr/foodaddy) was developed to upload the education materials along with up-to-date information and classroom activities for teachers on food additives. Fourth, the developed homepage was evaluated by applying to about 100 children and parents each, and majority of them showed high levels of understanding (children 85.7%, parents 79%) and satisfaction (children 77.2%, parents 64%), and the effect of getting over the prejudice against food additives was observed. The RC model developed in this study could be applied to any food risk communication, and the content and materials in this web site including booklets, animations, and quiz could be used effectively to promote the communication on food additives. In the future, it will be necessary to advertise the web site to be utilized by various consumer levels and to update the contents continuously by developing consumer-friendly communication materials.

In this paper, we aim to draw up an alternative instruction scheme by designing a web based instruction model on mathematics. Some learning materials are developed according to the scheme, and its educational effects are examined when it is committed to through regular curriculum. The study is composed of three major parts; setting of the theoretical foundation on cultivating Web based educational materials, design and composition of Web based teaching-learning model, and its experiments in the regular class. First of all, we are concerned with the core principles on WBI including the learning theories, developing learner oriented instruction model, design as well as build-up process for education materials, and strategy in instruction. Next, we propose an alternative instruction model for mathematics, in which programs to embody mathematics education and instruction on the Web are constructed, on the while, the study is proceeded through the Web Site. Finally, we design and produce a WBI instruction model on the subject of the plane quadratic curves. This model is examined in the regular class to estimate its educational effects compared with traditional teaching standpoints. Concomitantly, we explore essential elements and the direction of future growth associated with the Web oriented education.

This paper presents the status of nutrition education for older adults in Korea, and examines considerations in developing effective nutrition education programs for the elderly based on literature reviews. Finally, strategies of nutrition education for older adults in Korea are examined. Status of nutrition education were examined by surveying 90 senior centers, and 46 public health centers providing nutrition services. Most senior centers(96%) provided health education programs, however, nutrition was only a part of health programs. Among the 41 public health centers which responded to the survey, 73.1% provided nutrition education for older adults. The frequently covered topics were prevention & management of hypertension/stroke, diabetes, nutritional management during later adulthood, and osteoporosis. Common barriers in planning and implementing elderly education were; lack of educational materials for older adults, reliance on lectures, difficulty in following-up. To develop effective nutrition education, four stages consisting of needs assessment, planning and implementation of programs, and evaluation should be carefully done. Needs assessment might be done using quantitative or qualitative assessment. Factors influencing nutrition behavior of older adults can be systematically examined using a theoretical approach such as the PRECEDE-PROCEED framework. Qualitative methods, such as focus group interviews, also provide insightful information regarding the needs of older adults. In planning nutrition education programs, physical and pshychological changes associated with aging should be considered. Literature regarding elderly education suggest that active participation or participatory learning is also effective for older adults. Educational materials are developed following the principle of KISS and pre-tested. Program evaluation has been rarely done in practice, although it provides valuable feedback to the program. Strategies for developing nutrition education for Korean elderly include; performing needs assessment, developing a standard program by topics in a logical and systematic way, developing programs for subgroups of elderly, applying diverse education methods developing educational materials for the elderly, evaluating programs using simple tools, and delivering a nutrition program as a part of health promotion program. Finally, the interaction and communication between researchers and practitioners is strongly recommended to ensure better nutrition education and services to the elderly.

Many schools of the secondary level have been recently carrying out 'differentiated class'based on ability grouping between classed(DC). They are usually consisted of three levels; high level available to enriched course, middle level, and low level available to supplemental course. Phrhaps, almost all of the schools might nave executed DC before 2000 year. To do this, a lots of teachers have to develop differentiated teaching and learning materials for themselves. But, these mateirals are usually consisted of differentiated mathematics not on 'content'but on 'items'. So, for the successful 7th differentiated curriculum, the issues such as teaching and learning methods, materials, and evaluation system should be considered in depth focused on DC. .Decide issues related to DC(for example, mathematical contents, methods, activities, class speed,extra)based not on teachers or experts but on students. .Differentiate teaching and learning mateirals according to DC and develop the materials(including guidelines, supplementary books, multimedia, extra) based not on mathematical items but on mathematical contents. .Introduce new mathematical concepts or laws using not only not only definition and explanation but also concrete examples or problems. .Suggest differentiated diverse projects related to mathematical subjects suitable to enhance students` thinking ability to each class. .Have students to develop projects successfully by collecting, representing, analyzing, and interpreting data through communications in a cooperative learning environment.

Concepts in mathematics have been formulated for unifying and abstractizing materials in mathematics. In this procedure, usually some developments happen by necessity as well as for their own rights, so that various interesting materials can be produced as byproducts. These byproducts can also be established by themselves mathematically, which is called byproduct mathematization (sub-mathematization). As result, mathematization and its byproduct mathematization interrelated to be developed to obtain interesting results and concepts in mathematics. In this paper, we provide explicit examples：the mathematization is the continuity of trigonometric functions, while its byproduct mathematization is various trigonometric identities. This suggestion for explaining and showing mathematization as well as its byproduct mathematization enhance students to understand trigonometric functions and their related interesting materials.

For the moderns who spend more than 80% of the time inside a building, interior environment became important since it directly affects their health. Recently as noxiousness of the air contaminants of the interior space stood out as well as the above trend, the Ministry of Environment enacted a lawto maintain the interior air quality at certain level of standard in the multi use facility and newly constructed apartment. To make the indoor air clean, removal technology of various contaminants should be developed and interior materials with chemical treatment should be restrained. In other words, selection of interior finish affects indoor air quality from the initial design stage to the construction stage. However, only limited contaminants emission data of building materials are supplied by related companies. There is no average contaminants emission data for overall materials. Moreover, high cost and equipments for one time measurement of VOCs emission of interior finish are the obstacles of active research and data measurement. Therefore, this paper searched the current condition of average VOCs & HCHO emission of various interior finish based on the study requested to research center from the building material company through Stands Test Method for Indoor Air Quality.

The present study examines the effects of periodic type diffusers for producing the preferred acoustics for speech and determines the more successful configurations of sound-absorbing and diffusing treatments for achieving good acoustics in classrooms. The measurements were carried out in a 1/10 scale model classroom systematically adding diffusers to one or more of four surfaces of the room. A total of 13 combination of diffusers with absorptive treatments were investigated. Adding diffusers on the ceiling were more effective to increasing the early-arriving reflection energy($G_{50}$) than adding absorptive materials on the entire ceiling. The late arriving reflection energy($G_{late}$) was decreased with increasing amounts of diffusing treatments of upper front or rear wall and this resulted in achieving higher early-to-late ratios($G_{50}$). Adding diffusers on the upper front wall($AC_{100}DUFW_{26}$) achieved more uniform acoustical conditions over the receiver positions than adding diffusers on the upper rear wall($AC_{100}DUFW_{26}$). Adding diffusers on the ceiling and absorptive materials on the lower front wall($AC_{75}DC_{25}ALFW_{26}$) achieved better acoustical conditions than adding the absorptive materials on the entire ceiling and lower front wall($AC_{100}ALFW_{26}$).
