As the idea and function of the 'Model House' alters, so does the name - 'Housing Exposition' or 'Housing Cultural Center'. Its function Is not only to show and sell but to educate, promote and show culture. It works as a 'communication ground' about house. With the growing number of the Housing Cultural Center and the importance of function, major construction companies are building it competitively to connect the relationship with clients by expanding service. However, despite the necessity of 'Housing Cultural Center' is increasing, function and component of the Housing Cultural Center are yet defined and also specific direction of design, consumer services and programs are not properly established. Also, they are promoting and selling in lots only for a limited period which have problem in clients to participate and know about the characteristics of each companies promotion. Most of Housing Cultural Centers are similar in concept, shape, color use. The purpose of this research is to analyze the Housing Cultural Center with spacial and visual elements that comprise Housing Cultural Center, and study identity factors, distinct characteristics and build identity of the Housing Cultural Center. Ultimately, companies need to put forth to make difference in their own identity and apply it effectively in order to firmly establish identity.

The antibacterial and insecticidal properties of ethanol extracts and volatile components extracted from Eugenia caryophyllata, Boswellia carerii, Agastache rugosa, Aristolochia contorta, and Aquilaria agallocha were evaluated. The ethanol extract and volatile component of E. caryophyllata showed strong antimicrobial effect against all strains (Mucor hiemalis, Aspergillus niger, Penicillium funiculosum, Trichodema viride) and the volatile component of B. carterii showed antimicrobial effect against all strains except T. viride. The ethanol extract of E. caryophyllata and A. contorta showed $100\%\;and\;32\%$ mortality against Reticulitermes spertus kyushuensis Morimoto for 48 hours and 72 hours, respectively. In the case of volatile component, R. aryophyllata showed $100\%\;and\;20\%$ mortality against R. spertus and Lyctus linearis GOZE, respectively. The main constitute, eugenol $(92\%)$ among nine components from volatile component of E. aryophyllata were identified as antibacterial active substance.

Since the advent of man there has been a constant struggle to define social pattern, and understand ways of cultural thinking. Every culture has it's own limitations and freedoms, problems and expectations. For centuries now anthropologist, ethnographers have worked on mapping and defining these differences. These findings instigate the designers to formulate new design theories and research methodologies for drafting cultural specific solutions. The question arises 'in a cross cultural application how effective and applicable are the basic research methodologies'? Quoting one such example the 'Privacy' issue seems to be a very strong component in the Japanese culture but is often a deterring factor in allowing the 'home ethnographic study to take place effectively'. However in countries like India similar studies could have a more welcoming reaction owing to the adaptive social culture. Similarly, the high rate of 'Illiteracy' in rural India closes many doors for 'form filling' user surveys. This leads to the scope of research for understanding specific cultural traits that may effect adaptation and re-improvisation of these existing methodologies. Quite often the cultural traits of a country may lead in forming new research methodologies.

This study shows the comparison of chemical compositions of main component with other bronze bells after the research on the component analysis by non-destructive XRF analysis. There are shrinkage cavities caused by the shrinkage defect and pores with pollutants on Bronze Bell of Heungguksa Temple with gamma radiation images and 77.3% of copper, 8.4% of tin and 10.9% of lead were determined as the main components of it with XRF analysis The tin content of Brozen Bell of Heungguksa Temple is less than those (11~18%) of other bronze bells but the lead content of that is higher. The lead content of it shows 10.91% which is quite high while generally the lead contents of other bells were controlled lower than 2.1%. Buddhist bells have the different lead content according to the period. The lead content was low until Silla Dynasty and Unified Silla period but it has been getting higher since some point of Koryo Dynasty. It is assumed that expensive copper and tin were replaced with lead.

Digital images of cultural relics captured using line scan cameras present limitations due to uneven intensity and low contrast. To address this issue, this report proposes a colour linear array image enhancement method that can maintain a constant colour. First, the colour linear array image is converted from the red-green-blue (RGB) colour space into the hue-saturation-intensity colour space, and the three components of hue, saturation, and intensity are separated. Subsequently, the hue and saturation components are held constant while the intensity component is processed using the established intensity compensation model to eliminate the uneven intensity of the image. On this basis, the contrast of the intensity component is enhanced using an improved local contrast enhancement method. Finally, the processed image is converted into the RGB colour space. The experimental results indicate that the proposed method can significantly improve the visual effect of colour linear array images. Moreover, the objective quality evaluation parameters are improved compared to those determined using existing methods.

The pattern recognition methods of chemometrics have been applied to multivariate data, for which ninety four Korean ancient glass pieces have been determined for 12 elements by neutron activation analysis. For the purpose, principal component analysis and non-linear mapping have been used as the unsupervised learning methods. As the result, the glass samples have been classified into 6 classes. The SIMCA (statistical isolinear multiple component analysis), adopted as a supervised learning method, has been applied to the 6 training set and the test set. The results of the 6 training set were in accord with the results by principal component analysis and non-linear mapping. For test set, 17 of 33 samples were each allocated to one of the 6 training set.

The availability of enokitake cultural waste for Lentinus edodes cultivation was investigated, although hardwood sawdust has traditionally been used as a substrate for this fungus. Firstly, physiochemical characteristics of cultural waste were analysed. Secondly, mycelial growth characteristics and fruiting yields of L. edodes on waste treated in some methods were determined. Physiochemical characteristics of enokitake cultural waste showed that the millwaste complex was a little degraded by enokitake fungus and suggested the probability that most component lost by enokitake could be rice bran. Mycelia of L. edodes grew and fruited well on waste supplemented by fresh rice bran and Quercus sawdust although didn't on waste only. Mycelial growths of these fungi on waste were accelerated when supplemented by rice bran to the percent of 40(w/w) but decreased or suppressed at above ratios(30, 40%, w/w). Supplementations of oak sawdust at above 40%(w/w) of the waste and rice bran at 20%(w/w) of the sawdust allowed such a good mycelial growth as to be selected as a pertinent mixing ratio for fruiting medium. A fruiting yield on enokitake cultural waste supplemented by oak sawdust (at 40% of the waste, w/w) and rice bran (at 20% of the sawdust, w/w) was not inferior to that on oak sawdust supplemented by rice bran only (at 20% of the sawdust, w/w). These results indicated strongly the potentiality of enokitake cultural waste as raw materials for shiitake cultivating substrates.

This study focused on analyzing solid brown cosmetic residues that were excavated from the tomb of the Hwahyeop princess. The cosmetics had been buried in 1752 in Cheonghwa Baekja (small porcelain jars) within a Huigwakham (a stone box sealed with lime). A literature search and chemical analyses of the relics were conducted at the National Palace Museum of Korea. Based on the results of these analyses, raw materials and manufacturing methods for reproduction of the cosmetic were selected and then cream-form cosmetics were prepared. Aging tests using heat, ultraviolet (UV) radiation, and CO₂ were carried out to emulate the deterioration of the excavated cosmetics. Further chemical analyses and functionality tests were performed to evaluate changes from the tests and the effect as a cosmetic. As heat aging progressed, among the reproduced cosmetics, the one which has a high proposition of oil showed a color difference value of 32; the oxidation of oils involved chemical changes in O-H and C=C groups. As the cosmetic cream deteriorated under UV aging, the pH value became acidic. The result of the functional coverage test of the reproduced cosmetic cream was lower than the standard coverage ratio of modern cosmetics.
