본 연구에서는 공사현장에서 사용하고 있는 칼라 부직포의 화재위험성을 평가하기 위하여 콘칼로미터와 수직화염전파성 실험을 실시하였다. 그 결과 칼라 부직포는 표변에 화염이 착화가 되는 것이 아니라 용융이 된 상태에서 가연성가스가 발생되어 착화되는 연소형태를 보였다. 수직화염전파성 실험의 경우 가열강도에 의해 칼라 부직포가 수축 및 파단되어 화염이 전파되지 않을 정도로 열에 매우 취약하였다. 총방출열량은 2.66 MJ/$m^2$로, 건축물 실내마감재료 난연성능평가의 준불연재료(10분), 난연재료(5분) 8 MJ/$m^2$ 이하 기준에 규합되지만 이것은 내장재의 기준으로 칼라 부직포가 난연성능을 가지고 판단할 수 없으며 외장재에 대한 난연성능과 실험방법에 대한 기준이 마련되어야 한다고 판단된다.

1. Objectives: This study was performed to research the relationship between Sasang Constitution and characteristics of tongue diagnosis based on Donguisusebowon's Experience prescriptions(經驗方). 2. Methods: We searched tongue diagnosis factors in Donguisusebowon and classified this. Based on Donguisusebowon's Experience prescriptions(經驗方), we find tongue diagnosis factors in 6 contemporary Oriental medicine prescription books. 3. Results: Most So-eumin has white thin tongue coating and clear redish tongue color. Yellow tongue coatings are found in symptoms for Yinjinho-tang(Yinchenhao-tang), Soseungki-tang(Xiaochengqi-tang), Daeseungki-tang(Dachengqi-tang). Shortened Tongue is found in So-eumin's experience prescription and So-yangin's treat histroy. It didn't shown that So-eumin's Semen Crotonis included 6 prescritions' factors of tongue diagnosis. So-yangin's white tongue coating is found in Hyungbangpaedok-san(Jingfangbaidu-san), Sipjo-tang(Shizao-tang), Sosiho-tang(Xiaocihu-tang), Shinki-hwan(Shenqi-wan). Most of other So-yangin's tongue coatings are Yellowish and tongue color is deep red. Tae-eumin have thin white tongue coating at the Mahuang-tang(Mahuang-tang). Red tongue color and drying tongue are found at Jowiseungki-tang(Tiaoweichengqi-tang)Daesiho-tang(Dacihu-tang)Saengmaek-san(Shengmai-san) 4. Conclusions: Following So-eumin's Experience prescriptions, So-eumin's tongue color is clear red and tongue coatings are thin white and greasy. Following So-yangin's Experience prescriptions, So-yangin's tongue color is deep red and tongue coatings are yellowish and scarce except Exterior cold disease. And So-yangin has specific symptom of irritability, oral sores. Tae-eumin's tongue has two sides of white thin tongue coatings and Red and drying tongue.

Wood has always been used for various day-to-day applications such as interior or exterior construction materials, and household products. However, it can undergo photodegradation and discoloration by environmental factors including ultraviolet (UV) light, and thus has shortened its service life. Bleaching or delignification of wood surfaces is a suitable solution to stabilize wood against weathering by UV because these techniques can alter or remove the chromophores in lignin, which is a main factor of wood discoloration. To improve the color stability of wood surface according to the lifespan, surface delignification was conducted using peracetic acid (PAA) and hydrogen peroxide (HP) on the woods of Larix kaempferi and Quercus mongolica. After the PAA treatment, L^* increased considerably from 60-70 to 90-95. Furthermore, wood surface color did not change significantly after UV exposure. The color differences (𝜟E^*) between before and after PPA treatment of wood showed the 4.8-12.2 of L. kaempferi, and 1.7-3.7 of Q. mongolica, respectively. The lignin-related peaks in Fourier transform infrared spectroscopy (FT-IR) spectra disappeared with increased duration of PAA treatment. These results confirmed that the lignin component was partially or completely removed after the PAA treatment; the color differences (𝜟E^*) clearly showed that there was a reduction in redness (a^*) and yellowness (b^*), and an increase in lightness (L^*) owing to the removal of lignin. Based on these results, this study demonstrated that the partial removal of lignin from wood surfaces is a fundamental method for resolving photo-degradation.

본 논문에서는 복합 컬러모델과 얼굴특정 정보를 이용하여 실시간으로 얼굴영역을 검출 추적하고 기울어진 얼굴영상을 보정하는 시스템을 제안하였다. 제안한 시스템은 YCbCr과 YIQ 컬러모텔을 사용하여 얼굴 후보영역을 검출하였다. 얼굴 후보영역에서 수평 수직 투영기법을 사용하여 얼굴을 검출하고 하우스도르프 정합 방법을 사용하여 얼굴을 추적하였다. 또한 검출된 얼굴영상으로부터 눈 특징자의 기울기 정보를 보정함으로써 얼굴 기울기를 보정하였다. 실험결과 제안한 알고리즘이 주위환경 변화가 있는 실시간 얼굴검출과 추적 및 기울어진 얼굴인식에 강인하였다. 실험에서는 110개의 테스트 얼굴 영상을 사용하여 좋은 성능결과를 얻었다. 실험결과 얼굴검출과 얼굴추적율은 각각 92.27%와 92.70%를 나타내었고 얼굴 정보들로부터 90.0%의 얼굴인식율을 얻었다.

The subject of this paper is to find out the characteristics of Michael Graves' housing design. I collected the information of his designs and teamed his design language through his works on different time. I chose five actual housings for analysis which were built since 1960 when he have started his career. Though analysis of the exterior view, plane figures and the total arrangement photos, I could reached the conclusion. From analysis of this research I could figure out the characteristic of Michael Graves housing design as follows. During his whole working career $(1960\~present)$, his design style has went through distinctive characteristic changes that can be divided into: 1960s to early 1970s, mid and late 1970s, 1980s to as of now. 1960s to early 1970s, during this period his works implicated transparency, openness, consistency, complication, and contrast on space, abstraction, white-color and metaphor. mid and late 1970s, showed the white-color figure put together with geometrical structure and post-modernism styles such as ornamentation, natural and metaphor. 1980s to as of now, implicated ornamentation, natural features, historic background, interconnections, variety, symbolism and tradition.

This study aims to analyze the typological characteristics of Alvar Aalto's library design. The unique characteristics of Aalto's architecture are the result of accommodating Modern architecture with regional qualities of Finland. Besides this, Aalto's typological approach in design made his color. The library might be the best example for understanding his design approach in that he showed 3 main features of type; wholeness, self-control and transformation. He established architectural types in his 30s through Viipuri public library and developed so-called fan type library plan. Aalto's library type is not a simple copy of exterior and interior form. It acts as a principle of configuration of his library architecture and applied to the building. Therefore, Aalto's library architecture can be recognized as the results of typological design approach in that it shows the transformation of type in according to factors including site, size, region and cultural tradition. In conclusion, Aalto's libraries reveal the typological characteristics in the field of building layout, dynamic space and the effective use of light.

The purpose of this study was to prove that there is inherently golden ratio and color harmony in nature and to investigate some examples that have applied this elements in and out of construction . This is to provide a momentum to explore another new principles of nature and apply them to not only interior but also another design field. Under this purpose, the author of this study reviewed general theories on golden ratio and colour harmony and related them to leaves of plant and flowers to consider. As a result, it has revealed that theoretical golden ratio and colour harmony coincide with the order of nature, and this has made the author to investigate certain examples applied some orders owe can see in the plants to the interior or exterior parts of construction. There are lots of principles in nature still unrevealed to us, and therefore we must consistently make efforts to study new formative orders to apply them.

In the recent years, domestic construction companies have tried to differentiate their apartments using brand positioning. Respective construction companies are attracting public attention with discriminative brands. This study investigated residents' preferences focusing on apartments facade design used in marketing strategy of brand apartments. Four concepts in surveyed brand apartments are deluxe, modern, eco-friendly and comfortable. According to the related study on design factor of apartment facade, the design factors are chosen such as the overall building shape, balcony form, main color, exterior wall shape, material, main access shape, pent house design and window size. As a result of analysis, there was a difference between brand concepts and consumers' views. Therefore, apartment facade design to differentiate their own companies' brand images should consider the perception of customers.
