This research was carried out to sublimate our design with common sence so that the de-sign concept with our traditional chara-teristics can be acceptable in the world design area through re-creation works of tradition to be adoptable to modern concept. Form this survey the following could be derived. 1. in Korea designers should concern about the ration of skirt to jacket plait of Chima and string Koreum of hanbok. however they should pay more attention to string and color stripes to attract foreign customers in international market. It was found that koreans prefer the elegant and cur-vaceous design while foreigners demend edecor-ative design of Hanbok in addition to its el-egance and curvaeouseness. 2. It was also found that korean ramie fabric might be the most popular material for hanbok in Korea however silk and fine gauze might have to be used in international market. Generally it would be better to use the materials with natural and delicate feelings in Korea while the materials with gorgeous feel-ing in addition to natural and delicate feeling should be used in international market. 3, For the figures on Hanbok the embroidery figures and pictorial figures would be appropri-ate in Korea while it is necessary to develop the design with embroidery figures and gold foiled figures to satisfy the foreign customers. Accordignly it 8is required to develop the designers with figures with more elegant and gorgeous sence in both Korea and the world area.

Environmental impact assessment (EIA) is a tool used in planning development strategies and projects, and its use has been adopted into planning regulations in a number of countries. EIA has progressed from the consideration of pollution assessment, through the wider range of ecological assessment. Now EIA is required to consider the textbook of university students. Students taking lesson on EIA textbook are generally majoring in a variety of subjects, including environmental engineering, environmental health, environmental science, city planning, civil engineering, public policy, economics, and applied earth sciences. However, substantiality program of teaching material on EIA textbook has not been studied at expert society in the meantime, though a number of EIA textbook have been published every year in Korea. In current study, we presented the point at issue and improvement method of teaching material of EIA for student using domestic and foreign teaching materials and papers.

The purpose of this paper is to examine which fashion brands are most likely to be investigated by Korean textile firms when they conduct their market trend analyses. The result shows that for the domestic sales, textile firms are most likely to collect and analyze information on the Cheil Textil Co. It is followed by Bean Pole, Chanel, Buberry, Tomboy. For the future domestic sales, textile firms prefers referring foreign fashion brands such as Burberry, ZARA, MaxMara, Missoni, and Chanel. Textile firms majoring exports prefers collecting and analyzing information on D&G followed by Chanel, Gucci, and DKNY. This preference, however, differs when considering exporting areas. Textile firms targeting the French market considers Gucci, followed by Ferragamo, Dior, Louisvuitton. Textile firms targeting the Italian market prefer Chanel, followed by Valentine, ZARA, Gucci, and Armani. Chanel is also top brand for the North American and Japanese markets, and followed by GAP, ZARA, OZOC, Missoni, Munshing Wear. The information content collected and analyzed by textile firms is style, pattern, color, and textile materials for textile firms targeting the domestic sales, while the exporting firms prefer information on color and textile materials proposed and presented by the fashion brands to which they prefer to make reference. The result of this study can be used to effectively and efficiently collect and analyze market information on fashion brands for textile firms majoring the domestic and foreign sales.

A lot of foreign objects(ceramics, pottery, bronze, glassware and coins, etc.) have been found in the archaeological sites in Korea. These foreign objects are the evidences of the cultural exchanges of that time, whose scale and routes are an important part of the studies in ancient history. So it is crucial to accumulate basic reference information such as the raw materials and the production method of these objects through scientific researches, along with archeological researches. These scientific research materials provide a basis for finding the importing route and the origin of these objects. Besides, we can find out extraordinary and distinctive production technique by comparison with tile domestic objects. This article reports the result of an analysis, performing on 36 samples of the glassware fragments excavated from the South Tomb of the Hwangnamdaechong, to verify their components and note peculiar features. We have analyzed the major and minor components of 10 elements, and then by using these data examined the differences in the composition of components, varying with the origin and color of glassware. We used the PCA(principal component analysis) as the statistical method to classify the sample in order to find out how the samples formed groups.

Multiferroic materials are of great interest because of its potential applications in the design of devices combining magnetic, electronic and optical functionalities. Among various multiferroic materials, $BiFeO_3$(BFO) is known to be one of the intensively focused mainly due to the possibility of multiferroism at device working temperature (> $200^{\circ}C$). However, leakage current and weak polarization resulting from oxygen deficiency and crystalline defect should be resolved. Furthermore the magnetic ordering of pure BFO mainly prefers to have antiferromagnetic coupling. Up to now many attempts have been performed to improve the ferromagnetic and the ferroelectric properties of BFO by doping. In this work, we investigated the effects of Ni substitution on the multiferroism of bulk BFO. Four BFO samples (a pure BFO and three Ni-doped BFO's; $BiFe_{0.99}Ni_{0.01}O_3$, $BiFe_{0.98}Ni_{0.02}O_3$ and $BiFe_{0.97}Ni_{0.03}O_3$) were synthesized by the standard solid-state reaction and rapid sintering technique. The XRD results reveal that Ni atoms are substituted into Fe-sites and give rise to phase transition of cubic to rhombohedal. By using vibrating sample magnetometer and standard ferroelectric tester, the multiferroic properties at room temperature were characterized. We found that the magnetic moment of Ni-doped BFO turned out to be maximized for 3% of Ni dopant.

$CoSb_3$ Skutterudites materials have high potential for thermoelectric application at mid-temperature range because of their superior thermoelectric properties via control of charge carrier density and substitution of foreign atoms. Improvement of thermoelectric properties is expected for the ternary solid solution developed by substitution of foreign atoms having different valances into the $CoSb_3$ matrix. In this study, ternary solid solutions with a stoichiometry of $Co_{1-x}Ni_xSb_3$ x = 0.01, 0.05, 0.1, 0.2, $CoSb_{3-y}Te_y$, y = 0.1, 0.2, 0.3 were prepared by the Spark Plasma Sintering (SPS) system. Before the SPS synthesis, the ingots were synthesized by vacuum induction melting and followed by annealing. For phase analysis X-ray powder diffraction patterns were checked. All the samples were confirmed as single phase; however, with samples that were more doped than the solubility limit some secondary phases were detected. All the samples doped with Ni and Te atoms showed a negative Seebeck coefficient and their electrical conductivities increased with the doping amount up to the solubility limit. For the samples prepared by SPS the maximum value for dimensionless figure of merit reached 0.26, 0.42 for $Co_{0.9}Ni_{0.1}Sb_3$, $CoSb_{2.8}Te_{0.2}$ at 690 K, respectively. These results show that the SPS method is effective in this system and Ni/Te dopants are also effective for increasing thermoelectric properties of this system.

This article intends to explore the formation of furniture terms with the name of furniture, furniture materials, tools, and machinery from eight furniture companies manufacturing their own different furniture items. As a result of this study, the terms can be abstracted as four things as follows. First of all, the terminology that the furniture firms is are unified over 80 percent and has no problem on the communication among the companies. Especially office furniture all is using common words because the terms are almost fixed by an administration agreement relating to the Supply Administration. Second, the furniture terms being used at the fields are mixed with Korean, English, and Japanese, and this current state shows more at small businesses than at large businesses Third, the terms of foreign words, almost English, present 48 percent as 156 words among the total 325 terms. Japanese shows 6 percent as 21 terms but it tends to be handed down from mouth to mouth with inaccurate conditions. Finally, the formation of the terms are from the original words or English, from the combination of Korean and foreign words for convenience at the fields, and from being created as Korean newly in considering Korea's special situation.

The main mineral phases of natural hydraulic lime (NHL) as a hydraulic lime binderare $Ca(OH)_2$, $C_2S$, $C_3S$, $C_3A$, and $SiO_2$ residues. Also, NHL has the characteristic of setting and hardening by a hydration reaction with water and by carbonation reactions with carbon dioxide from the air. In this study, in an effort to investigate changes of the mineral phases by NHL hydration and carbonation reactions, transitions of mineral phases and the microstructures of hardened pastes were analyzed by XRD, DSC, SEM, and by pore size distributions using domestic and foreign-sourced NHL pastes after curing at 1, 3, 7, and 28 days. On the basis of the analysis results, it was confirmed that domestic low-grade limestone can be used for the manufacturing of NHL. The main hydration mineral phases were $Ca(OH)_2$, $CaCO_3$, $C_2S$, and $SiO_2$ residues, while in the case of foreign-sourced NHL, a small amount of an aluminium hydration phase formed. Also, the $CaCO_3$ content after the carbonation reaction increased with an increase in the curing time. After hydration for 28 days, NHL containing considerable amounts of $C_2S$ and $C_3S$ showed higher carbonation ratios than others types.

This study is the 2nd report following "A Study on the Characteristics of Material in the Korean Up-cycling Fashion Brands (Part I)" that handled the development of upcycling props using the characteristics of upcycling material. The 2nd report analyzed product types and materials focusing on 21 foreign upcycling fashion brands. It analyzed the characteristics of upcycling fashion materials using the case analysis of coffee bean bag and waste denim based on external characteristics and internal characteristics. We then classified the external characteristics into environment/economic feasibility and availability/mixture and the internal characteristics into historicality/story and originality/scarcity. Five bags were designed and produced for the actual commercialization of fashion products based on such characteristics of materials, with the use of coffee bean bags and waste denim as upcycling materials. This study is differentiated from existing research by its suggestions for the utilization of fashion product upcycling coffee bean bags and waste denim. Also, upcycling fashion products could be competitive products in eco-friendliness and originality that can be a driving force for the sustainable development of fashion industry through the differentiation of existing fashion products.
