To investigate the purchasing pattern for domestic furniture, this study surveyed the 1,050 customers aged from 20’s to mid 50’s through online. The researcher made questionnaires with 6 question items and the participants were asked twice for a month in October, 2018. The survey results are as follows. The first, the most important element that customers consider in purchasing furniture is furniture quality all ages. The next considerations are materials, price, and design in order. The second, TV ad is considered the most effective information collection route before customers purchase furniture. The next effective routes for gathering information about the furniture are TV dramas, TV home-shopping, newspapers, and magazines in order. Among online media, the first source customers searcher for to get information about furniture is an internet shopping mall and the next things are internet communities, company’s home-pages, company’s blogs, and SNS in order. In offline media, catalogue is considered the best information source and the next sources are a furniture exhibition or a display show, leaflets, and banners in order. In terms of stores where customers visit most frequently to get information, the first shop they go to get information about furniture is a brand furniture shop and the next places are distribution market, furniture complex, and the stores with furniture promotion events in order. The third, the most difficult element customer think in the process they choose proper furniture and get information in purchasing is to find out a product with good durability. The next processes considered difficult in order are checking whether materials are eco-friendly or not, whether the product size fits for customer’ house and the furniture would be harmonious with the other furniture or home appliances, and whether the price of furniture is reasonable. The fourth, for the question asking about the places they purchased furniture within the last year, the first place is a brand furniture shop or a street stores. The next places are general internet malls, brand furniture’s internet malls, and local furniture complex in order.

The study of traditional color -after KIST’s research between 1972 and 1973- has been done for 40 years until now. This research has been performed in various ways, and depending on the performer, subject, purpose and method of research it has drawn different results in the studied . Such results of research are being copied and circulated on the internet, and they are even being quoted in school’s textbooks, scholarly books, academic theses and dissertations without proper verification procedures. Hence, the object of this research is to make a foundational study to propose research methodology to help getting the right information about Korean traditional colors. For that, we chose Red as a representative subject and made a comparison and analysis about its preceding studies. The result shows that the traditional color Red’s research was done through various ways like measuring colors of relic·object·light source, studying based on the meaning of the words, measuring color after reproducing color formation by following literature research, conducting quantitative and qualitative research, using such methods combined and so on. I also have found out that the result of the research could only be different from each other as a matter of course. and we analyzed the pros and cons and problems of each methods. The major problem is subjective interpretation about traditional color. Through the result of this research, we drew a very natural conclusion that the traditional colors research requires characteristics of systematic colors, traditional colors, object's colors, light-source colors, ect and needs objective and scientific methods in selecting relics for color measurement, in reproducing traditional color formation and in many other situations. The research has a limitation that it was performed with only "Red" as a subject - among many fundamental colors of traditional colors. From now on research with extended scope and research with all the preceding research results integrated should be performed. 한국의 전통색에 관한 연구는 1972-1973년 KIST의 연구 이래 40여년에 이른다. 이러한 연구의 연구자, 연구대상, 연구목적, 연구방법에 따라 다양하게 이루어졌으며, 도출된 서로 다른 연구결과물들은 명확한 검증절차 없이 인터넷은 교과서, 학술서적, 학위·학술논문에 인용되고 있다. 이에 본 연구는 한국의 전통색에 대한 정확한 정보를 얻기 위한 연구방법론을 제시하기 위한 기초연구를 목적으로 대표적 사례로 적색(赤色)을 선정, 선행연구를 비교·분석하였다. 연구결과 적색의 연구방법은 측색, 문자적 의미, 문헌·고증에 따른 재현, 정량·정성조사, 앞의 방법들을 혼용하는 등 다양하게 이루어졌으며, 당연히 연구결과 역시 각기 다름을 또한 확인할 수 있었다. 이를 통하여 전통색에 대한 주관적 해석이 문제라는 점을 확인할 수 있었다. 결과적으로 본 연구를 통해 전통색 연구는 계통색·관용색, 물체색, 광원색 등 각 색의 특성과 측색을 위한 유물 선정방법, 전통색의 발색 재현 등에 대한 객관적이고 과학적인 방법이 필요하다는 지극히 당연한 결과를 얻을 수 있었다. 본 연구는 전통색의 기본색 중 적색만을 중심으로 했다는 한계성을 가지고 있으며, 향후 연구범위를 확대한 연구와 현재까지의 선행연구결과를 통합한 연구를 진행할 예정이다.

This study is tertiary study about five relations colors and coexistent five relations colors. In primary research, new traditional color diagram was adduced to reinterpret traditional color through only chromatic, achromatic and secondary dispense with semantic base on traditional color as formal, relations and coexistent. In secondary research, to identify central axis consist of chromatic color-red, yellow blue(赤黃靑)and secondary color- hun, green and jung(纁綠靘)compared with visible ray spectrum. Hun(纁) and jung(靘) are discrepancy between orange and violet. To identify hun and jung, checked and researched literal exegesis, existing research and literature on traditional color. Result of research, basis of literal exegesis were found that traditional color hun is red-yellow and the same as orange. Secondary color between red and yellow is orange(橙色, 朱黃) rather than hun were found through existing research and literature. Finally, six traditional chromatic color name correspond with spectrum, at least. Then it is hard to deny a possibility that traditional color were based on color physics and ideas were well in advance of the age of Newton’s spectroscopy experiment. Existing dichotomous thinking that traditional color were based on symbolism and semantic and western one were based on color physics and rationality should be modified. This study range is white as five formal color, secondary color hong(紅 色), gyu(硅色)and byuk(碧色). To identify white and color name of hong, gyu and byuk, comparative study was performed with advanced study. White was proved that it was device to extend color through mixture with chromatic color. Differentiation of color name between‘Korean traditional color’based on Isusinpyeon, Gyuhapchongseo and advanced study was ascertained. Finally, though traditional color was exquisite system even long history, exquisite study about color name and tree attribute of color were insufficiency. This study have limitation that did not suggest an alternative though identified defect through literature research about color name. Following study to identify five formal color and ten secondary color will proceed through the results of tertiary study. 본 연구는 오정색(五正色)과 십간색(十間色)에 관한 3차 연구이다. 1차 연구에서는 전통색의 의미론적 근간인 방색(方色), 상생(相生), 상극(相剋)을 배재하고 유채색, 무채색, 간색의 개념만으로 재해석하고 이 개념을 새로운 정간색도(正間色圖)를 제시하였다. 2차 연구에서는 1차 연구결과 중 정간색도의 중심축인 정색 적색(赤色), 황색(黃色), 청색(靑色)과 간색 훈색(鑂色), 녹색(綠色), 정색(靘色)을 가시광선 스펙트럼의 색 이름을 문헌, 선행연구를 통해 비교 연구하였으며 특히 서로 일치하지 않는 훈색과 정색을 중심으로 한 연구결과 훈색은 주황(朱黃), 등색(橙色)과 정색은 남색(藍色)과 유사한 색임을 확인할 수 있었다. 이 결과는 전통색의 색채 물리학적 인식을 바탕으로 하며 이는 서양보다앞섰을 가능성과 전통색의 상징적의미론적이고 서양은 합리적이라는 기존의 이분법적 사고는 수정이 필요하다는 것이다. 본 연구범위는 오정색 중 유채색 적색, 황색, 청색과 무채색 백색(白色)과 간색 홍색(紅色), 규색(硅色), 벽색(碧 色)이며, 오정색에서 백색이 가지는 의미와 홍색, 규색, 벽색의 색 이름을 중심으로 선행연구와 비교 연구하였다. 결과로 백색은 유채색과의 혼합을 통한 간색으로 색을 확장해 나가는 장치로서‘색은 변화가 셀 수 없이 많으나 오색을 벗어나지 않는다.’라는 원리를 확인할 수 있었다. 색 이름 비교 연구를 위한 선행연구 조사결과 이수신편(理藪新編)과 규합총서(閨閤叢書)를 기반으로 한‘한국의 전통색’과는 홍색, 규색, 벽색뿐만 아니라 십간색의 많은 색에서의 차이를 확인할 수 있었다. 결과적으로 전통색의 오래된 역사에도 오정색, 십간색 구조는 색채 물리학적으로 정교하다는 것을 확인할 수 있었던 반면 이러한 논리적인 정교성을 뒷받침할 수 있는 색 이름과 색의 삼속성에 대한 자료와 연구부족은 문제점이라는 것을 확인할 수 있었다. 본 연구는 오정색과 십간색의 전반적 구조를 파악할 수 있는 연구결과 도출에 이르지못했다는 한계성과 문헌 등을 중심으로 색 이름을 비교연구하여 문제점을 파악에 그쳤다는 한계 또한 지니고 있다. 향후 3차까지의 연구결과를 종합, 오정색과 십간색의 전반으로 파악하기 위한 연구를 진행할 예정이다.

We proposed a content-based image retrieval system with a simple and effective relevance feedback. First, texture features are extracted from the images in the image database by using Gabor wavelet transform. Next, the extracted features are used for image retrieval in various ways. We applied the relevance feedback to the intial retrieved images from the image retrieval system, and compared its result with that of the conventional system. In the experiment using the image database of 16 class 512 images, the proposed method showed better retrieval performance of about 8% than that of INRIA in each relevance feedback step.

Neutrophil may play a role in clinical asthma and humoral mediator including biologically active lipids and complement fragments are implicated in the pathophysiology of asthma by activation of neutrophil. To evaluate the presence of humoral mediator to activate neutrophil functions in times of adherence and the relation of this functional change of neutrophil with the concentration of complement fragments in the attack of bronchospasm. We measured the neutrophil adherence after treatment with serum of patients with bronchial asthma and after inactivation of serum with heat and the concentration of C and C . The results were as follows. 1) Serum of patients with bronchial asthma accentuated neutrophil adherence more than that of normal controls. 2) Heat inactivation abolished the adherence enhancing effect in serum of patients with bron- chial asthma. 3) Concentrations of C and C were higher in the serum of patient with bronchial asthma compared to normal controls but did not well correlate with neutrophil adherence. 4) Neutrophil adherence enhancing factor may have molecular weight of 2,000,000 and between 160,000 and 100,000. These data suggest that the patients with bronchial asthma might have heat labile mediator to enhance neutrophil adherence, possibly not through complement activation.
