  • In this study the mechanical behaviors of fiber metal laminates(FMLs) such as ARALL, GLARE and CARE which are recently developed as new structural materials and known to have excellent fatigue resistant characteristics while with relatively low densities compared to the conventional aluminum materials, are considered through the classical lamination theory. The mechanical properties such as elastic moduli, thermal expansion coefficients and hygro-thermally induced residual stresses in the fiber metal laminates are obtained and compared each other. Also, carpet plots of effective elastic moduli, Poisson's ratio and the thermal expansion coefficient for GLARE FML are plotted.

  • Each ethnic group has different cultural backgrounds and each culture has developed with its own traditions. The interaction between different cultures is getting more active through acculturation and cultural contacts. The purpose of this study was to compare domestic living of Korean immigrants with Australians in the form of a Cross-Cultural study. For this, usage of domestic space and seating style of 52 Korean households and 53 Australian households in Melbourne were analyzed. Ethnographic research with questionnaire was used. The results of the research were as follows. 1. The most popular type of Living-Dining-Kitchen arrangement was L+ K. D for Koreans and L. D . K for Australians. 2. A laundry room was indispensable for both and they all wanted to do ironing in there as well as dry. Both were satisfied with the type which toilet was separated from the bathroom Drain hole on the floor of the bathroom was not indispensable for most Koreans and Australians. 3. Koreans and Australians were doing various activities in living area and both were getting together around kitchen(dining) area. The particular thing of Koreans was that they were using the main bedroom with multiple purpose. 4. The seating style of Koreans and Australians belong to chair-seating style generally. But Koreans were using floor seating style in making bed for the guest and making Kimchi. Koreans and Australians were using mixed style of floor seating and chair-seating in relaxing time with watching TV, treating guest or so. 5. Koreans were not satisfied with using carpet cause of dust but Australians were satisfied with the carpet cause of warmness. 6. Most Koreans and Australians were take off shoes inside of the house. Koreans were organize shoes around the front door of the house usually and Australians were organize shoes in bedroom usually. 7. The most popular heating system was ducted heating for both. The level of satisfaction about ducted heating was low for Koreans because they though that it could contaminate air. Australians were satisfied with ducted heating because they though that this one was fit on the weather of this area. 8. Living room was the most important one for Koreans and Australians and they also thought it should be decorated well for entertaining guests. Most Koreans were estimate that the brightness of the light of the house was not enough but it was estimated to moderate for Australians on the contrary.

  • Nine soil media when placed over a plastic sheet with three seeding rates were evaluated for influence on covering rate, height, growth, surface hardness, tear strength and sod establishment of Kentucky bluegrass. 1. Bark, peat and vermiculite over a plastic sheet had good effect in terms of the establishment of Kentucky bluegrass sod. 2. The good establishment of Kentucky bluegrass sod grown on bark, peat and vermiculite over a plastic sheet seemed to be caused by physical and chemical properties of each soil medium. 3. Sand, sandy loam, perlite and peatmoss caused poor effects on the covering rate, the growth, and the tear strength of Kentucky bluegrass. 4. Optimum seeding rate was $10g/m^2$ in terms of density and competition. 5. Good quality sod more depended on soil media than on seeding rates in this study.

  • William Morris(1834-1896) was the most versatile and talented of all British nineteenth century polymaths. Since his death over one hundred years ago his achievements as an artist, designer, manufacturer, shop-keeper, poet, author, publisher, printer, collector, teacher, conservationist, political activist and environmentalist have influenced the lives and work of people throughout the world. Moris is now best known for his attractive and colorful patterns. The decorating firm of Morris, Marshall, Fault & Company(Morris & Company after 1875) was established in 1861. Over the years it produced works, ranging from stained·glass windows and furniture to tapestries, carpets and printed and woven fabrics, that had great influence on the course of British design. His earliest experiments with the craft were amateurishly worked embroideries made for his own use. Before long, Morris began to produce textiles on a more commercial basis. In order to control production properly, Morris set about learning the various textiles techniques, first dyeing and blockprinting, hand-loom jacquard and eventually, carpet and tapestry weaving. This extraordinary involvement with the practical side of manufacture separated Morris from all other designers of his time and contributed in no small way to his success. Morris's designs for textiles, embroidery, dyeing, woven, carpet and tapestry were commercially produced, that are most universally admired and frequently copied today. These have a timeless quality arising from the designers respect for and knowledge of the technique. Of equal importance was his love of nature, evidence of which can be seen in even the smallest details of each of his patterns.

  • The purpose of this study is to analyze the uses and exterior design of the balconies in urban housing from the ancient times to the 19th century. In doing so, the paper seeks to investigate the cultural identity of the balcony in urban housing. The results are as follow. First, in the urban housing the balcony space were made for protection from the heat, light and ventilation; gardening; views toward the streets, city, waterside, inner court, domain for men; breathing french air; watching ceremony, festivals and events; simple houseworks like drying, carpet cleaning and hair coloring; lever installation and fire escape. Second, as part of exterior design the typical projecting characteristic of the balconies was emphasized and they became an impotent decorative element. The monotonous facade changed to a lively design with a rhythmical sense. On the facade the effects of horizontal movement, symmetry or asymmetry from the main entrance, and the center-projection (rialto) were created. In the urban housing the balconies were used for cultural activities which supplement and enlarge the function of the interior space, and moreover the rich effects of the facade contributed to the creation of attractive urban landscape.

  • Aldehydes are irritants of the upper respiratory tract with symptoms such as eye, nose, and throat. Formaldehyde classified in Group 2A by the International Agency for Research on Cancer and a probable human carcinogen by the Unite States Environmental Protection Agency due to its carcinogenicity. Aldehydes may be emitted from many other consumer products, such as permanent press fabrics, cosmetics, fiberglass insulation, paints, and coatings. The purpose of this study was to examine the does-response relationship between aldehydes levels and symptoms (eyes, nose, throat, and respiratory) for 36 dwellings and 280 households in Korea. As a result, environmental factors affecting aldehydes level were indoor smoking, ventilation, using of carpet, bed, and new furniture, painting for renovation, and indoor humidity. There wat weakly positive correlation between symptom score and aldehydes level.

  • This study covers the stages of testing whether the azo dye with chemical name (E)-5-[(4-(benzyl(methyl)amino)phenyl)diazenyl]-1,4-dimethyl-1H-1,2,4-triazol-4-ium zinc (II) chloride (DMT), known as Maxilon Red GRL in the dye industry, can be used as an anticorrosive feasible inhibitory agent, especially in industrial areas other than carpet, yarn and fibre dyeing. These test stages consist of the electrochemical measurement techniques such as potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) for diverse concentrations and durations. The adsorption of the viewed DMT molecule on the mild steel surface obeyed the Langmuir isotherm. The zero charge potential (PZC) of mild steel was also found to assess the inhibition mechanism in containing DMT solution. The inhibition performance of DMT on the mild steel in a 1.0 M HCl solution was also investigated using methods such as metal microscope, atomic force microscope (AFM) and field emission scanning electron microscope (FE-SEM).

  • This study was carried out to find the cases of change in the Anglican Church including its rectory in Onsuri, Gangwha island, which was built in Korean traditional architecture style. The materials used for the study were published books, old photos taken before the change, drawings, and field survey. The result are as followings. 1) Painting concealed natural wooden grain should be removed as well as carpet on the wooden floor. The way of ceiling finishing is to be restored as traditional way. 2) Refer to the rectory, it needs to be restored totally, since it has been changed many times through partial renovation. It lacks unification of design in entire elevation, windows and door. The practical spaces such as indoor flush toilet and boiler room are desirable not to be revealed or designed in harmony with other spaces. 3) Stript flooring in the rectory are to be restored to frame flooring, room finishing including vinyl flooring, vinyl wall paper and moulding along the cornice to the traditional paper finish. Lattice patterns of windows and doors are recommended to be restored according to the traditional design.

  • Dyeing wastewaters are the most problematic wastewater in textile industries and also, growing amounts of waste fibers in carpet industries have concerned environmental specialists. Among different treatment methods, membrane filtration processes as energy-efficient and compatible way, were utilized for several individual problems. In this research, novel hybrid membranes were prepared by waste fibers of mechanical carpets as useful resource of membrane matrix and industrial graphite powder as filler to eliminate Chrysophenine GX from dyeing wastewater. These membranes were expected to be utilized for first stage of hybrid membrane filtration process including (adsorption-ultrafiltration) and nanofiltration in Kashan Textile Company. For scaling of membrane filtration process, fouling mechanism of these membranes were recognized and explained by the use of genetic algorithm, as well. The graphite increased rejection and diminished permeate flux at low concentration but in high concentration, the performance was significantly worsened. Among all hybrid membranes, 18% wt. waste fibers-1% wt. graphite membrane had the best performance and minimum fouling. The maximum pore size of this optimum membrane was ranged from 16.10 to 18.72 nm.

  • The research was conducted to quantify farm and household characteristics of sheep farmers, evaluate farmer access to and the effectiveness of livestock services in sheep farming areas, and examine regional constraints to improving sheep productivity and profitability in Nepal. A rapid diagnostic socioeconomic survey of 200 sheep farmers was carried out in 1996 and all four ecological regions (Trans-Himalayan, Mountains, Hills and Terai), each with a distinct local sheep breed, were represented in the survey. Six major constraints were identified: (a) poor performance of local sheep breeds, (b) a serious seasonal deficit of pasture and other feed, (c) the lack of an organized market for wool and meat, (d) poor access to agricultural credit, (e) primitive shearing equipment, and (f) an inadequate supply of drinking water for sheep. Strategies to assist farmers develop their sheep management skills, improve access and quality of support services, improved technology adaptable to local conditions and effective linkages with local carpet and meat industry are likely to overcome the constraints and alleviate persistent poverty faced by sheep farmers in Nepal.
