The ceremonies were roughly categorized into four： coming of age, marriage, funeral and ancestral worship. Among them, the funeral was a representative example to show ancestral worship. As it symbolizes the worship to ancestors, its procedure was complicated and formalized. It was undoubtedly certain that formalized mourning dresses and complicated table setting for sacrificial services to ancestors were burdens. Although what was symbolized by mourning dresses was different depending on the wearers purposes, it was thought that no clothing had such unusual symbolism as mourning dress. When the composition of mourning dress was examined, it was shown that Taoism, family relation of Confucianism or symbolic clothing system of Shamanism were combined. Mourning dress first represented the Confucian idea of ancestral worship. For the composition of clothing in which a shamanistic element was inherent, forms of birds were used to guide the dead soul to the other world. In cutting out mourning dress, opposite concepts of Yin and Yang, and closure and openness were used to show a harmony between heaven and the earth. Male and female were represented through sewing techniques. The period of observing the mourning period depended on the degree of kinship. The degree to which the clothing was loose indicated the degree of sadness and kinship. Load blocks and tear pads indicated the degree of sadness. In considering the above indicators, family relation and filial piety to ancestors had a great effect on the form and details of mourning dress. Shamanistic elements as well as Confucian ones were inherent in mourning dress, which resulted in the combination of Taoism and Confucianism.

The relative composition of $Cu(InGa)Se_2$ solar cells is one of the most important measurement issues. However, quantitative analysis of multi-component alloy films is difficult by surface analysis methods due to severe matrix effect. In this study, quantitative depth profiling analysis of CIGS films was investigated by secondary ion mass spectrometry (SIMS). The compositions were measured by SIMS using the alloy reference relative sensitivity factors derived from the certified compositions and the total counting numbers of each element. The compositions measured by SIMS were linearly proportional to those by inductively coupled plasma-mass spectrometry (ICP-MS) using isotope dilution method. In this study, the quantification measured by ICP-MS method is compared with the composition calculated by SIMS depth profiles with AR-RSFs obtained from the reference. The SIMS depth profile of CIGS thin films according to the manufacturing condition was converted into compositional depth profile.

Duplex stainless steels have the dual microstructure of austenite and ferrite phases. This steel exhibits generally a high corrosion resistance and higher mechanical strength compared with austenitic stainless steels. The steels used in the investigation have the chemical composition of Fe-22Cr-xNi-yMn-0.2N in which the contents of Ni and Mn were varied with maintaining the equal [Ni/Cr] equivalent. The fraction of ferrite phase was increased with the increase of annealing temperature. The impact factor of Mn element on the [Ni] equivalent was amended on the basis of the results of the investigation. 4Mn-2Ni alloy showed the highest pitting corrosion resistance. The fraction ratio, grain size and misorientation angle between grains were measured, and the correlation with pitting potential was investigated.

Sn was selected as an alloying element of Cu. The Cu-Sn thin layers were deposited on the Si substrates by the electroplating method and their properties were studied. By rapidly thermal annealing(RTA) up to 40$0^{\circ}C$ after electroplating, sheet resistance decreased and adhesion strength increased, but that trend was reversed at the 50$0^{\circ}C$ RTA. Cu-Sn particles grew dense and the surface was uniform up to 40$0^{\circ}C$, but at 50$0^{\circ}C$, empty area was introduced and the surface became rough owing to oxidation and particle coarsening and agglomeration. Deposited layer contained significant amount of Si, while pure Cu-Sn layer with the composition ratio of 90:10 was present only on the top surface. However, no significant change in the Cu composition within alloy layers occured by the RTA regardless of its temperature. This indicates that the Cu diffusion into the Si was suppressed by the presence of Sn.

Na-Fe Tourmalene ($NaFe_3Al_6B_3Si_6O_{27}F_4$)single crystals were grown by FZ method. The Growth conditions are counter rotation 20~30rpm, growth rate 1~5mm/hr in the atmospheric environment. The transition elements as Fe(in this research), Mn, Co, etc, are exist in the theoretical fomulae so that dopants were not added. The feed rod was sintered between $1000^{\circ}C$ and $1l00^{\circ}C$, but at higher temperature, it was difficult to manufacture the feed rod because of evaporation of the elements such as F. As grown crystals had a black color and the length of 50~60mm, the diameter of 5~6mm. X-ray powder diffraction pattern indicated that the composition of the feed rod was right to the Tourmaline composition. By FT-IR spectra, the state of bonding of each element was charaterized.

The purpose of this study was to the characteristics of the interior space composition for luxurious apartments and the trend of interior design. Surveying visits were made to 30 model houses for which individual apartments of 8 million Won or more per pyeong (about 3.30 square meters) were on sale from December 1999 through November 2000 in Seoul and suburb area, pundang. The major finding were summarized as follows; (1) The characteristics of the planes indicated that the living-room separation type accounted for the majority, which was not generally different from common apartments. The master zone divided several room. The main room which conventionally played the roles of the family gathering space and the second room shared by family members, was designed exclusively for husband and wife. Distinctively separated from the other spaces, it was to be used for personalized space, together with bathroom for the couple, dressing room, or study. Attempts were made for the high-class apartments to get away from the common uniformed apartments, such as the yard-type balcony or the second entrance in consideration of the moving path. (2) The characteristics of the interior designs showed that the detailed attention was paid to every composing element for the emphasis of the high quality image. The factors determining the quality were finishing materials, kitchen furniture, hygienic ceramics, electrical appliances water supply equipment, or functional storage closet.

We investigated the effects of the chemical composition and the relative density on the plastic deformation behavior of sintered Fe-based alloys by means of compressive tests. Overall compressive stresses increased as the amount of alloying elements and the relative density were respectively increased. Addition of alloying elements except for Mo increased the yield stress regardless of the relative density. The relationship between the effects of the chemical composition and the relative density and the mean rate of the stress increase was analyzed. A constitutive equation based on the Ludwik equation with the regressed parameters was proposed to predict the compressive true stress-true strain curves of the sintered Fe-based alloys. The K and n values used in the proposed equation were regressed as a function of the alloying elements and the relative density based on the individual K and n values. The plastic deformation behavior predicted using the proposed constitutive equation showed reliable accuracy compared with experimental data.

To meet demand of big capacity and high speed rotation for washing machine, more stress from bending and twisting are complexly loaded onto the shaft supporting the horizontal drum, causing problems in fracture strength and fatigue life. Also, Vibration occurs due to the frequency of the rotating parts. But, shaft has various design factors such as diameter and distance between bearings according to configuration of shaft, the optimal values can't be easily determined. Using a design of experiment (DOE) based on the FEM (Finite Element Method), which has several advantages such as less computing, high accuracy performance and usefulness, this study was performed investigating the interaction effect between the various design factor as well as the main effect of the each design factor under bending, twist and vibration and proposed optimum design using center composition method among response surface derived from regression equation of simulation-based DOE.
