Community building has been carried out from around the year 2000 by various statutes and government policies in Korea. This study suggested direction of the future for rural community building as surveyed cases of completed four villages in Gurye-county. In order to achieve this study's objectives, investigated previous studies and interviewed 75 person's residents in cases villagers. The target villages are Sangsa, Omi, Chamsaimigol and Artists village. As survey results, four villages utilized local resources, most of villages were focused perform hardware. On the other hand, Chamsaimigol was parallel software. In addition, communities didn't form and not agree with concept of community building as culture, education, welfare, etc., also didn't creation the case of village income. but active village as base development. Therefor, proposed the point to education, culture and welfare, base development and generating of income as directions for future rural community building. These directions are consistent with the concept of community building and the goal that improve the quality of life of residents ultimately through community building.

Among the ancient ideas of East Asia, there is a myth about the symbol of the Four Gods who commands all directions in the east, south, west, and north, and this is also reflected in the medical field. However, although there is discussion about Qinglong Decoction (青龍湯), Baihu Decoction (白虎湯) and Xuanwu Decoction (玄武湯) in the 『Shanghan Lun (傷寒論)』, there is no content focusing on Zhuniao decoction (朱鳥湯). Considering the consistent perspective of 『Shanghan Lun』, which recognizes the disease-syndrome and seeks prescriptions based on yin and yang thinking, this is very unusual. Therefore, in this study, it was revealed that the concept of 'Sishen Decoction (四神湯)' itself was a concept that emerged when the authors of 『Shanghan Lun』 established the 'eight-principles syndrome differentiation (八綱辨證)' system in their recognition and response to diseases-syndromes. Based on this, I considered the following possibilities: They were able to present Qinglong decoction, Baihu Decoction and Xuanwu decoction, as appropriate prescriptions for 'exterior cold excess syndrome (表寒實證)', 'interior heat deficiency syndrome (裏熱虛證)', and 'interior cold deficiency syndrome (裏熱實證)'. However, it is possible that the name of the prescription 'Zhuniao decoction' was not intentionally used, because it was not possible to provide an appropriate prescription for 'exterior cold excess syndrome (表熱實證)'.

Mammography, conducted every two years, causes cancer due to regular exposure to radiation while reducing rate of death caused by breast cancer. The study evaluates the effect of breast shielding apron made to shield off scattered radiation that occurs to the breast when the opposite side breast is mammogramed. AGD was measured using ACR phantom, composed of 50% mammary glands and 50% fat, and radiation was measured before and after wearing the apron on the breast when the opposite side of the breast is mammogramed. When CC direction mammography was conducted to a breast, the AGD was 1.84 mGy. When CC direction and MLO direction mammography were done to a breast, the average dose detected from the opposite side breast from four directions(top to bottom and medial to lateral) was $140{\mu}Gy$ with maximum dose of $256{\mu}Gy$ at medial side. After putting on the apron, the dose, caused by scattered radiation, was not detected from any of the four directions. Using of breast shielding apron is expected to minimize the radiation exposure by blocking scattered radiation to the breast shielded, when mammography is done to the opposite side breast.

This research was to analyze the direction ideas of residential Feng Shui. In ancient China residential places were been established by Xiangzhai(相宅) and Buzhai(卜宅) usages. And ancient Chinese always considered geographical features of mountains and waters for setting up their living places. Geographical features were also considered importantly ih representative residential Feng Shui books, Zhaijing(宅經) and Yangzhaisanyao(陽宅三要). In Zhaihing, 24 direction ideas are co-related with Fagui(八卦) and GanZhi(千支) theories, and they are most important residential Feng Shiui direction theories. The basic thoughts of 24 direction ideas of Zhaijing were already formed in Qin(秦) dynasty and modified in early Han(漢) dynasty. In Zhaijing, residential places were splited into Yangzhai(陽宅) and Yinzhai(陰宅) according to YinYang's Qi directions. Those were actually formed from meticulous observations on changing processes of YinYangWuXing(陰陽五行)'s Qi(氣). Constantly changed Qi of YinYangWuXing were studied by old chinese people from the observations on the sun, the moon, the five stars, the Great Bear, and ErShiBaXiu(二十八宿). The origin of Zhaijing's direction ideas is the direction system of ShiPan(式盤) in Qin and Han dynasty. On ShiPan TianGan(天干) Dizi(地支) Fagui TianDiRenGui(天地人鬼) were arranged very systematically into four and 24 directions. DongxiSizhai(東西四宅) theories of Yangzhaisanyao had edited more lately than Zhaijing(宅經), and formed according to Fagui(八卦)'s YinYang(陰陽) principles. But the basic ideas is same with Zhaihing's. It proves that residential Feng Shui theories were constantly improved and modified. And both residential Feng Shui direction ideas of Zhaijing and Yangzhaisanyao are the gentral ideas in old china. The point of that ideas is Sky's four or 24 directions are correspndence with the earth's. It came from the traditional thoughts that Heaven, Earth, and mankind are c0-related and influenced each other according to Qi's changing processes. Gather up above mentioned, the direction ideas of residential Feng Shui is a systematic thoughts of old chinese for harmonizing Tian-Di-Ren-Gui, and is their specific methods for harmonizing the nature's Qi, mankind and spirits.

In large liquid crystal displays, the image quality in an oblique viewing direction is a crucial issue. From this perspective, 8-domain polymer-stabilized vertical alignment (PS-VA) mode has been developed to suppress the color shift in oblique viewing directions, compared to that in 4-domain PS-VA mode. To realize the 8-domain PS-VA, the four domains in a pixel are each divided into two regions, such that applying different electric potentials result in different tilt angles in these two regions, while keeping four azimuthal directions in each domain. However, applying different voltages in a pixel causes drawbacks, such as requiring additional processes to construct a capacitor and a transistor, which will further reduce the aperture ratio. Here we propose a different approach to form the 8-domain, by controlling surface polar anchoring energy and the width of patterned electrodes in two regions of a pixel. As a result, the gamma-distortion index (GDI), measured at an azimuthal angle of $0^{\circ}$, is reduced by about 23% and 8%, compared to that of a conventional 4-domain at polar angles of $30^{\circ}$ and $60^{\circ}$ respectively.

To evaluate the anisotropic characteristics of Korean traditional paper-Hanji, the physical and mechanical characteristics of hand-made hanji, and machine-made hanji were investigated in this research. The densities of copying paper and newsprint paper appeared to be two times higher than the densities of hand-made hanji using Ssangbal sheet forming and hanji made of paper mulberry fiber. The breaking length, and tear index of both Hanji using Owangbal sheet forming, and hand-made Hanji using Ssangbal sheet forming appeared to be different according to the directions in paper. The breaking lengths of Hanji using Owangbal sheet forming showed little differences according to the directions. Breaking length of Hanji using Ssangbal sheet were slightly higher than those of Hanji using Owangbla sheet forming. The breaking lengths of machine-made hanji, copying paper, and newsprint paper were two to four times higher than those of hand-made Hanji. The breaking length showed higher differences according to the direction than the tear index. The tensile strength according to the directions in paper showed significant differences (${\alpha}$=0.05) in all papers used in this research.

Recently, the development of aerospace and automobile industries has brought new technological challenges, rebated to the growing complexity of products and the new geometry of the models. High speed milling with a 5-Axis milling machine has been widely used fur 3D sculptured surface parts. When turbine blades are machined by a 5-axis milling, their thin and cantilever shape causes vibrations, deflections and twists. Therefore, the surface roughness and the waviness of the workpiece are not good. In this paper, the effects of cutter orientation and the lead/tilt angle used to machine turbine blades with a 5-axis high speed ball end-milling were investigated to improve geometric accuracy and surface integrity. The experiments were performed using a lead/tilt angle of 15$^{\circ}$ to the workpiece with four cutter directions such as horizontal outward, horizontal inward, vertical outward, and vortical inward directions. Workpiece deflection, surface roughness and the machined surface were all measured with various cutter orientations such as cutting directions, and lead/tilt angle. The results show that the best cutting strategy for machining turbine blades with a 5-axis milling is horizontal inward direction with a tilt angle.

The aim of the present study was to investigate the effects of 6-week wrist resistance training on wrist torque control. Nineteen subjects were randomly assigned to either the wrist training group (n=9) or the control group (n=10). The training group performed wrist exercises for six directions (flexion, extension, pronation, supination, radial deviation, and ulnar deviation) while the control group did not. Testing for the isometric torque control error, one-repetition maximum (1-RM) strength, and isokinetic maximum torque (angular velocity of $60^{\circ}/s$ wrist movements) were conducted before and after six weeks of resistance training and after every two-week interval of training. The wrist training group showed significant decreases in isometric torque control error in all six directions after the 2-week resistance training, while the control group did not show significant increase or decrease. The training group showed significant increases in the maximum strength in all six directions assessed by 1-RM strength and isokinetic strength tests after the 4-week resistance training, while the control group did not show any statistically significant changes. This study shows that motor control ability significantly improves within the first two weeks of resistance training, while the wrist strength significantly improves within the first four weeks of resistance training in wrist training group compared to the control.

The purpose of this study is to suggest some interior design directions for university library in the circumstances of rapid change of user's demand for the library. In order to extract some ideas about designing the library, I analyzed the libraries of UC Berkeley which has tried to transform the existing condition of the building for satisfying user's new needs. Informations of compositions, layouts of furnitures and book shelves, environmental conditions of 25 branch libraries of UC Berkeley, and spatial behavior patterns in libraries were surveyed and analyzed to get insights to design a new model of library buildings. The interesting phenomena got from the survey is that most of the library users used their own laptop computer in the library regardless of environmental conditions of the library or book types. In conclusion, as the library is changing to the place of studying, not of reading books, four design directions for the library are suggested in this research as like these; 1) Establishing a Regulation Free Environment for a user, 2) Enhancing the Aura of Books as an Interior Design Element, 3) Supplying Personalized Spatial Characters, and 4) Providing an Impactful Space.

The object of this thesis is to develop an effective method for Five-in-a-Row. For this purpose, we develop a method that describes a move accurately, and a procedure that choses a move more effectively. In describing a move, we represent each move as eight vectors generated from four directions for both offensive and defensive strategies. Each vector consists of three components, that is, connectivity, agressiveness, and directions of stones in a line. In choosing a move, we introduce a preference order among all vectors by an expert's knowledge. Then, an efficient algorithm is developed to test a cycle in the preference order. Experimental results show that the success rate of this new method is about 90% against Weisenbaum's program known as the prototype of the Five-in-a-Row program.
