We fabricated cube-textured Ni and Ni-W alloy substrates for coated conductors and characterized the effects of W addition on microstructure, mechanical strength, and magnetic properties of the substrate. Pure Ni and Ni-(2, 3, 5at.%)W alloys were prepared by plasma arc melting, heavily cold rolled and then annealed at various temperatures of $600-1300^{\circ}C$. The texture was evaluated by pole-figure and orientation distribution function (ODF) analysis. Mechanical properties were investigated by micro Vickers hardness and tension test. Ferromagnetism of the substrate was measured by physical property measurement system (PPMS). It was observed that Ni-W substrates had sharp cube texture, and the full-width at half-maximums (FWHMs) of in-plane texture was $^{\circ}$-5.57$4.42^{\circ}$, which is better than that of pure Ni substrate. In addition cube texture of Ni-W substrates was retained at higher temperature up to $1300^{\circ}C$. Microstructural observation showed that the Ni-W substrates had fine grain size and higher mechanical properties than the pure Ni substrate. These improvements are probably due to strengthening mechanisms such as solid solution hardening and/or grain size strengthening. PPMS analysis showed that addition of W effectively reduced saturation magnetization in applied magnetic field and Curie temperature.

The pulse diagnosis is the basic method of oriental medicine diagnosis. But in sasang constitutional medicine, it is said that it's not a major diagnotic method. But we don't have any sasang constitutional study of the pulse diagnosis. So I made this study by research of changing concept of the pulse diagnosis in chinese medical history and Dongyi Suse Bowon (longevity and life preservation in oriental medicine). The conclusion as follows. 1. There were many kinds of the pulse diagnosis in the ancient times, it has developed to simple and effective diagnotic method. Simple and effective is the major point of medical development, the 24 pulse is abridged to Floating Pulse(浮), Deep Pulse(沈), Slow Pulse(遲), Rapid Pulse(數) 2. The latter term of Chosun, the practical study was developed. In the view of the practical study, the pulse diagnosis has a lot of cricical point. Jung Yak-Yong, in his writing Mak Lon(脈論), criticize the pulse diagnosis. 3. In the sasang constitutional medicine, the constitutional diagnosis is very important. The methods of the constitutional diagnosis are three, the way of mind and greed, knowledge and deed, external figure and physical traits. But the pulse diagnosis is one of the way of external figure and physical traits, so we can't diagnose the exact constitution by the pulse diagnosis. 4. Dong-mu conclude that the pulse diagnosis is just the diagnostic way of symptom. But in the clinical situation, the ordinary symptoms are more important than the pulse diagnosis, because it is useful to know the condition of the ingestive food metabolism and the Qi-yack metabolism

We fabricated the Au/Ni template for YBCO coated conductors and evaluated texture formation and the microstructural evolution. The cube textured Ni substrate was fabricated by rolling and recrystallization annealing, and subsequently Au layer formed on the substrate by electroless-plating method. The texture was evaluated by pole-figure with x-ray goniometer with orientation distribution function (ODF) analysis. The surface roughness and grain boundary morphology of template were characterized by atomic force microscopy (AFM) We observed that Au layer deposited epitaxially on Ni substrate and formed a strong cube texture when plating time was optimized. The full-width at half-maximum (FWHM) was $8.4^{\circ}$ for out-of-plane and $9.98^{\circ}$ for in-plane texture for plating time of 30 min. Microstructural observation showed that the Au layer was homogeneous and dense without formation of crack/microcrack. In addition, we observed that root-mean-square (RMS) and depth of grain boundary were 14.6 nm and 160 $\AA$ for the Au layer, respectively, while those were 27.0 nm and 800 $\AA$ for the Ni substrate, indicating that the electoless-plated Au layer had relatively smooth surface and effectively mollified grain groove.

It is identified that an initial person who built of 'Seoul Gyedong Modernized Hanok(former Min Hyeong-gi house)' used as 'Bukchon Culture Center' in present, was not Min Hyeong-gi, but his wife, Yu Jin-gyeong, and she built it when 8 years went on after his death(1879~1973), and the construction year was at the gate of Chuseok in 1921. Yu Jin-gyeong was Head Family's Eldest Daughter-in-law in family of Yeo Heung-min who was an influential person at the late Joseon Dynasty and was widow who had only son for 3 generations. And she built this house and moved to gain daughter and live futher grandchilds together in law in new nest. It is arranged that an annex surrounds with main building as the central figure. And this house emulates Yeonkeong-dang in backyard of the Changdeok Palace for 'preservation of main building' and Chim-bang-ga-toe applied on a bedroom in a palace is applied around nobleman family's the main room. It is rare case and expresses that a palace factor is borrowed. Yu Jin-gyeong's house is that a tradition Hanok is adjusted closely in city and central and basing mode as 'protective bedding' and building concept as 'a noble and protective architecture' is realized. So it has a character that development of Hangrang architecture is appeared and Head Family's Eldest Daughter-in-law widow of modern upper class had a special benefit. As well as, a meaning that it is experimental house based on tradition and is build of Hanok with housekeeping as the central figure for appear a form which has minimal Hangrang for housekeeping in yangban family of modern city, can be found.

In case of UHF Band Transceiver for Army Aircraft, it shall follow MIL-STD-461F Figure CE101-4 most key design points for this equipment were to minize the current consumption and frequency interference since it will be integrated on aircraft. However, after design, abnomal signal(over 100 dBuA) was occured from 30 Hz to 1 kHz on CE101 test. Occured abnomal signal was measured as 50 Hz signal which was tansceiver $T_{DD}$ signal with the output power of 10 W and 20 ms periods. To meet the specification, current variation needed to be minized. Thus, $I_{dq}$ and $I_d$ of power amplifier were modified almost equally through test result and finally, the equipment was designed and developed with no difference of current consumption and frequency interference from the previous design goal.

Since the cognitive science developed as a brandl of academic researdl, studies on human brains have flourished. Emotional features have been centered on the field of design, and the development of the design process has been diversified that makes use of the factors. The purpose of this study is to reflect the current trend and to convert the results into a method for designing. The researdl is based on the mind map techniques which spread like a trendy fashion, and tries to supply a theoretical explanation of how to overcome the fixed idea. Recognizing the importance of learned information in approaching a problem, I regarded the roles of left and right brain as analogue and digital images interpreting them by freely crossing language(digital images) and visual thought (analogue images), using mapping tedlniques. I pursued the research goal of the techniques focusing on the idea of using mapping. As a result of this. I established a logic system [figure 8] in that a proposition which starts as a problem introduction goes on until a problem solution, which is visualized with concept presentation, using a brainstorming technique. According to the suggested concept. I concluded that idea proliferation as a design demand can be solved by applying mapping techniques like one shown in figure 12.

This study aims at providing the basic information required for policies on return to countryside for farming or else, through analysing the actual state of settlement and the community of people returning to rural areas. The comparative analysis of people returning toward general village and sub-urban residential complex in rural has been done to figure out the settlement environment. And the status analysis targeting the people returning to rural areas and original residents who live in general village have been done to figure out the actual state of the community. As a result, people returning toward sub-urban residential complex in rural moved for something else, while people returning toward general village in rural moved with the purpose of farming. Like this, the aims of moving into rural areas show difference. There is little conflict between people returning to rural areas and original residents, but some people have an intention to move the other place due to the conflict with original residents. So the community revitalization is needed for the active responses and suitable adaptation of them. On the basis of this study, policy tasks for return to countryside for farming or else were suggested as follows; 1) It is necessary to formulate each policy on return for farming and something else to rural areas discriminatively. 2) The economic support for a stable settlement of people returning to rural areas and the programs activating community with original residents are required. The discussion about the new community formation is needed to respond to the increase of people returning to rural areas.

Geometrical figures have been used as artwork motifs from the ancient times to the present day. The area of fashion, being a part of modern art, is also largely influenced by geometry and geometrical shapes are being used as a motif for fashion design now more than ever before. However, studies about geometry in the fashion field are not yet done enough and further research is necessary. This research will therefore investigate the usages of round, square and triangular design in contemporary fashion. The main scope of this research is to look at the type of expression and analyze the intrinsic meanings of these shapes in modern fashion. This research will look profoundly into the general characteristics of these geometrical figures and analyze the effects and uniqueness found in the world collection introduced since 2007. As a result from this study, it was found that round and square objects were perceived in such a straightforward and positive way and these designs, when worn, really completed the final look. On the other hand, the triangular design was used mainly for spatial expansion and was interpreted in a more metaphorical, indirect and abstract way. The intrinsic meaning of round, square and triangle figures in contemporary fashion consists of the informal features that really steps out of the formative clothing structure. The topological changes that is formed from the interactive functions and the wholism that creates a new system through integration of the human body and clothing contains the intrinsic meaning of these geometrical figures. Based on the research results, the method of expression and the characteristics of modern day fashion's geometrical figures was able to be easily understood. This work provides the useful information on the development of fashion design and the extended interpretation of clothing structure.
