건축공사의 선진화는 시공기술과 함께 재료의 성능향상이 동반되어야 한다. 특히 습식공사의 경우 인력에 의한 의존도가 높고, 재료 사용의 다양화가 미진한 대표적인 공정이라 할 수 있다. 이와 같은 마감 모르타르 공사에서 품질 및 시공의 선진화를 위한 다양한 모르타르 재료에 대한 물리적 특성 시험을 통하여 비교·확인함으로 향후 습식 미장공사의 다양한 재료 적용과 기계화 시공을 넘어 친환경 기능성 재료의 사용까지 발전될 수 있도록 제안해 보았다. 특히 공장생산 제품인 건조시멘트 모르타르 제품을 기준으로 기계화 시공이 가능한 수지플라스터와 친환경 석고플라스터의 사용 확대를 위한 각 재료의 품질 특성에 관한 연구를 통해 마감 모르타르 공사의 다양화와 선진화 방향을 제시하였다. 그 결과 압축강도의 경우 시멘트를 기본으로 하는 재료에서는 초기 양생조건이 품질 확보에 가장 중요한 관리 항목임을 다시 한번 확인할 수 있었으며, 마감 모르타르의 작업 후 균열 안정성에 영향을 주는 길이변화의 경우 석고플라스터가 가장 우수한 결과를 나타냈으며, 최종 응결이 빠르게 나타남으로 후속 공정을 보다 빨리 진행할 수 있어 공기단축에도 기여할 수 있을 것으로 판단된다.

Unlike in the past, where the expression of the form was given a priority, with the widening of the scopes of the designs, the proportion of design education institution curricula targeting user experience and the application of technology is continually and gradually increasing. Open source microcontroller boards such as Arduino have initiated attracting attention as a countermeasure against these changes. These prototyping tools have many advantages for the diversification of expression and design verification in the design field and therefore have a high likelihood of being introduced into many design education institutes; however, the tools act as high entry barriers for design students who lack engineering knowledge. Although various educational content and tools have been developed to address the issue of barrier, existing solutions remain insufficient as alternatives for the purpose of activation. In this study, we investigated the present state of related education content and conducted a pilot workshop using a prototype microcontroller board with simplified coding. We intend to use the results of this investigation to develop study material for design education. We started by conducting a survey regarding the pre-university education situation. It was observed that engineering education opportunities are insufficient and the problem of mutual application between educations due to course-based education was not realized. We also analyzed the characteristics of simplified training tools using the microcontroller to establish a direction for educational design and conducted a pilot workshop using the microcontroller toolkit with a simplified coding process based on this content. Students who lack a basic knowledge of engineering technology received instruction, and after completing minimum preliminary training, they proceeded to practical exercises that involved utilizing the toolkit. Through this process, we identified the need for a simple-type microcontroller board with low-complexity for use in educating students majoring in design. We also identified some obstacles that serve as barriers to entry of utilizing microcontroller board. Based on these results, we propose several functional requirements and teaching guidelines for prototyping toolkits for design education.

The structural aesthetics of architecture are becoming an inspirational source for many fashion designers and have been reborn in structural fashion. This study planned to analyze the method of expression of structural aesthetics expressed in modern structural fashion design and the construction method to maximize such an effect on the basis of the construction characteristic of Santiago Calatrava as the representative architect of the structural aesthetic. According to the study, the structural aesthetics expressed in modern structural fashion design are as follows: 1) The symbolical formative aesthetic expressed by symbolical inference and analyzation; 2) the dynamic beauty of physic expressed by visual emphasis and dynamics; and 3) the asymmetric beauty of symmetry expressed by metastasis toward the boundary between balance and imbalance. In addition, to maximize structural aesthetics, we used repetition and a progressive technique based on rhythm, asymmetry, and incision-based variances, such as balance, polygon flux, and inference, and analyzation-based distortion as the structuring principle. The following expression methods for maximizing structural aesthetics were found: 1) symbolical and structural exaggeration of appearance; 2) detail technique expansion and material property diversification; and 3) the three-dimensional transformation of structure and shell expression. Structural fashion design was found to have maximized structural aesthetics by using such expression methods to secure artistic esthetics, destroy existing shapes and patterns, and create unique shapes.

범죄는 예방이 중요하게 강조되고 있다. 범죄행위 자체는 종류에 따라 차이는 있지만 많은 물적 인적 피해를 동반하기 때문에 시민생활의 안전을 위협하고 있다. 전통적인 방범활동은 경찰의 공권력에 의해 이루어져 왔으나 범죄의 다양화, 광역화, 조직화, 전문화, 흉폭화는 경찰의 방범기능을 훨씬 능가하여 발생되고 있다. 민간방범기구는 경찰영역의 보완적 관계에서 지역을 거점으로 활동하고 있으며 영리성을 목적으로 하는 경우도 있으나 많은 단체는 자생적이며 자율적이고 봉사적 성격으로 시민생활의 안전울타리로서 역할을 하고 있다. 그러나 이들 단체들의 역할에 걸 맞는 사회적 후원과 제도적 지원이 미흡하여 실질적이고 효율적인 방범활동의 효과를 거두지 못하고 있다. 법의 개정이나 역할의 중복성에 대한 기구의 정비, 또는 체계적인 조직망을 갖추기 위한 일련의 노력과 기능적 활용 등이 요망되고 있다.

The objectives of this study is to analyze the characteristics of Chinese traditionality expression at restaurants in Beijing area. 12 restaurants were selected and visited for the investigation research. The results were as follows. First, traditional reproduction was found mainly manifested through the reproduction of traditional ornaments, in particular, the facade and interior element ornaments. Second, Traditional transformation was mainly manifested in replacement material while changing the shape slightly, or to stretch or shorten prototype shape and other negative deformation methods which did not largely out of the scope of traditional reproduction. Third, Traditional reinterpretation was expressed by abstract, symbol or metaphor on designs, usually people can not directly recognize the traditional archetype. When compare with traditional reproduction or traditional transformation, traditional reinterpretation was relatively fewer, however, in this study the traditional reinterpretation and traditional transformation have same numerical result. Reinterpretation as a positive performance method of traditional modernized, it was encouraging the phenomenon, especially in the ceiling design. Chinese traditional cloud patterns have been three-dimensional and diversification of use. And in the wall design, traditional elements have been extremely simplistic or adopted a wide variety of traditional elements, it may be preferred in diversity. In addition, furniture was tinge traditional elements in modern form, lighting was added symbolize color or picture on the traditional lighting which shape was simplified to emphasize space's traditional. But the facade, sign board, floor, and window element seems the range of variation was not wild, promote more use the positive traditional reinterpretation method.

본 연구의 목적은 제 7차 교육과정에 의한 초등학교 과학 교과서에서 STS 내용을 분석하는 것이다. 연구의 주요 결과는 다음과 같다: (1) STS 내용의 포함 비율은 쪽수의 측면에서는 26%, 수업 시수의 측면에서는 40%이었다. '에너지'와 '물질' 영역에서의 비율이 높고 학년별 비교에서는 5학년 교과서에 포함된 내용이 상대적으로 적었다. (2) 대부분의 STS 주제는 기술이나 사회보다는 과학과 관련 있었다. (3) STS 내용이 한 시간 수업의 전체 과정에서 사용되는 경우도 많았다. (4) 대부분의 활동이 '그룹활동'과 '실험.관찰'에 해당하였고 '역할놀이, '현장견학', '인터뷰' 등의 활동은 거의 없었다. 이러한 결과는 개정된 교과서가 최근의 STS 교육사조를 잘 반영한다는 것을 의미한다. 그러나 STS 주제나 활동유형을 보다 다양화시키는 등 일부 측면에서의 개선이 요구됨을 시사한다.

Fur garment has long been the conventional symbol for luxury, or conspicuous consumption. However, as fashion items began to diversify as part of overall fashion trend, fur items are now more about individual taste and style than just lavishness. Synthetic fur is especially emerging as a new promising fashion material, with a touch almost like natural fur at an affordable price. Along with the emergence of 'Vegan Fashion' trend, synthetic fur is establishing itself as a popular fashion textile. This study is an attempt to investigate subjective evaluation and physical properties of natural and synthetic furs, whose results will further serve as basic data in developing synthetic fur materials. Sensory and emotional evaluations are carried out on natural and artificial furs. For analysis, factors such as weight, thickness, air permeability, gloss and compressibility were surveyed to observe how they influence the physical properties. According to the subjective evaluation, natural and artificial fur samples do not differ in conspicuous ways in appearance. Experiments on physical properties, specifically warm/cool touch experiment, show that natural fur has a slightly higher warm sensation than artificial fur. Luster analysis by using a microscope revealed that there are subtle qualitative differences between natural and artificial fur. During the subjective evaluation, subjects found it hard to state distinct quantitative differences in luster. A survey as a means of assessing qualitative differences in gloss seems to be necessary to complement the evaluation. Results from this study will potentially serve as resources for diversification of fashion product designs using synthetic fur.
