본 연구는 건축 공간의 실내음향 설계에 있어 보다 효율적이고 비전문가도 쉽게 활용할 수 있는 실내 음향 공간 모델링 및 음향분석 시뮬레이션 시스템을 개발하고 이를 활용한 새로운 음향 분석 절차의 제안 하는 것을 목표로 하고 있다. 이러한 시스템의 개발은 기존의 선형적인 실내 음향 공간 디자인의 문제점을 극복하고 건축음향 공간의 최적화를 위한 나선형 건축음향 모델링 및 분석 체계를 이루는 기반이 된다. Recently, the social desire in Cultural liiew is increased according to the wide-spread or Well-being Culture . In this manner, the necessity of good acoustic design of enclosed spaces is raised. In order to satisfy the citizen with cultural desire, the government has planed to create the recreation spaces such as auditoriums and theatres. Those spaces where sound quality is usually low are reproduced because of an inadequate acoustic design. Therefore, the development of a powerful acoustic design tool for public spaces is needed Nowadays, most of the existing acoustic simulation tools are always expensive and hard to use. As the result, our development in acoustic simulation tools aims on creating a local and user-friendly tool ^lich everyone can use. In tins manner, we suggest new acoustic design process using a expert design system using material styles and the space model library fra* the nonprofessional designer.

된장은 대두를 주원료로 하는 한국의 대표적인 전통발효 식품임이나, 국민건강영양조사에서 고나트륨을 가지는 식품군에 분류되었다. 각종 질병의 원인이 될 수 있는 나트륨 과다섭취에 대한 저나트륨 된장의 개발이 필요한 실정으로, 품질에 크게 영향이 없이도 나트륨 함량이 적은 장류의 개발은 지속적으로 연구되어야 하는 과제이다. 따라서 본 연구에서는 나트륨 함량을 12.5%-45%까지 저감하도록 실험을 설계하여 적용하여 된장 담금을 진행하였으며, 그 품질적 특성을 분석하고자 하였다. 나트륨의 저감화가 된장의 관능적 품질에 영향을 미치는지 pH, 염도 및 수분, 나트륨함량, 색도, 아미노산성 질소함량, 유리아미노산, 구성아미노산조성을 평가하여, 그 특성을 비교 분석하였다. 나트륨의 저감화는 pH와 수분, 염도에 크게 영향을 미치지 않았으며, 대조구와 같은 범위에서의 품질을 유지하였다. 나트륨함량은 실제로 비례적으로 감소되었으며, 아미노산성 질소는 500 mg%수준이었다. 대량으로 된장업체에서 제조한 25% 저염된 된장의 대체소재를 사용하는 것은 최종 된장의 나트륨함량을 줄이면서도 된장의 품질에 큰 영향을 미치지 않을 것으로 사료된다. Although Doenjang is a representative traditional fermented food in Korea, made mainly from soybeans, it has been classified into a food group identified as having high sodium in the National Health and Nutrition Examination. It is necessary to develop a low sodium Doenjang to prevent the excessive sodium intake which may cause various diseases. However, the development of Doenjang with low sodium, without significant changes on quality, is an ongoing challenge. Therefore, the experiment was designed to reduce the salt content of the soaking water to 12.5-45%. The pH, saltiness. moisture, sodium, color, amino-type nitrogen, free amino acids and constituent amino acids composition of Doenjang were investigated to determine the effect of this salt reduction on the sensory quality of Doenjang. The reduction of sodium did not affect the pH, moisture and saltiness, and this changed maintained the same range as the control. The sodium content was reduced proportionally, and the amino acid nitrogen level was 500 mg%. Therefore, this study considered that a reduction of 25% of salt in the soaking water does not affect the quality of the Doenjang while reducing the sodium content of the final Doenjang.

The concept of universal design has recently emerged as an important aspect of product design. Universal design is considerably analogous to ergonomic design in a way that it takes the capabilities and limitations of users into consideration during the product development process. However, relatively few studies have been devoted to reflect the practical use of ergonomic principles on universal design. This research attempts to develop a universal design index for mobile phone design to quantify how well a product complies with principles of universal design. The research also emphasizes on ergonomic principles as a basis of evaluation. A generation of the evaluation items was done by cross-checking among the personal, activity and product components. Personal components consist of human characteristics including age, physique, perceptual capacity, life-style, etc. Activity components were derived from those scenarios of mobile phone use while product components were composed of the parts to which a user interacts. Further analysis systematically generated a universal index from relationship matrices among the three components. The index was then used to test its suitability by applying to the evaluation of mobile phones currently on the market. This study demonstrates a development process through which evaluations can be made possible for universal design. The research suggests an improved approach to the appraisal of how well mobile phones are universally designed based on ergonomic principles.

Role-based access control (RBAC) models are recently receiving considerable attention as a generalized approach to access control. In line with the increase in applications that deal with spatial data. an advanced RBAC model whose entities and constraints depend on the characteristics of spatial data is required. Even if some approaches have been proposed for geographic information systems. most studies focus on the location of users instead of the characteristics of spatial data. In this paper. we extend the traditional RBAC model in order to deal with the characteristics of spatial data and propose new spatial constraints. We use the object-oriented modeling based on open GIS consortium geometric model to formalize spatial objects and spatial relations such as hierarchy relation and topology relation. As a result of the formalization for spatial relations. we present spatial constraints classified according to the characteristics of each relation. We demonstrate our extended-RBAC model called OOGIS-RBAC and spatial constraints through case studies. Finally. we compare our OOGIS-RBAC model and the DAC model in the management of access control to prove the efficiency of our model.

The purpose of this study was to examine the effects of children’s perspective taking ability using physical expression activities through a multi-cultural approach. The subjects consisted of 46 five-year-old children attending private kindergarten in Gumi city. The children were divided into the experimental group consisting 23 children who were given physical expression activities using a multi-cultural approach and the control group consisting 23 children who were given physical expression activities using a general approach. As a measure of young children’s perspective taking ability, the picture test tool of Kurdek and Rodgon(1975) which was used by Yung-Hee Kim(1995) was used. The study included the pre-test, the physical expression activities using a multi-cultural approach, and the post test. The data were analyzed with ANCOVA. The results of this study showed a significant difference between the experimental and the control group of the perspective taking ability, especially on spatial ability, emotional ability, and cognitive ability. These results indicate that by using physical expression activities through a multi-cultural approach, children are able to be more open minded, to understand the harm of prejudice, and to build cooperation skills.
