A feng-shui map is a kind of map that features such propitious positions as fortune-bringing spots or ideal grave sites. The map is a representation of the most ideal natural terrains in terms of feng-shui perspectives. This study did research on two feng-shui maps registered on some genealogical tables in order to see how the map was drawn up. In addition, the detailed characteristics of landform expressions like the frame of the map, viewpoints, center-oriented mapping, water flow, mountain theories were delved into. The results of the research are as follows: the feng-shui maps for this research used the techniques of double scale and aerial view, described terrains with grave sites in their centers, and enlarged important terrains compared with surroundings for exaggeration purposes. In addition, other vital landforms not observed from grave sites were depicted with viewpoints moved and were represented in fine details. The part of mountain theories had the following points as their main subject matter: geographical locations, overall orientations of mountain ranges, topographical traits, grave seat directions and surrounding terrains.

As recent inflows of foreign immigrants to relatively advanced countries in Northeast Asia have rapidly increased, Japan in particular uses 'multicultural coexistance' as a key concept for developing both discourse and policies on them. This paper is first of all to suggest a new typology of multicultural societies in the world ill order to differentiate the case of Northeast Asian countries from those of Western countries. And this paper is to suggest that foreign immigrants in Japan have different positions in labor markets and living experiences according to historical and social backgrounds as well as their nationality. The transformation process towards multicultural society is not only historical and social but also geographical and spatial, as foreign immigrants have made different spatial distribution and regional segregation in types. In order to control this socio-spatial process towards multicultural society, Japan has developed the concept of 'multicultural coexistence' similar with that of multiculturalism in Western countries. This concept seems to be quite significant as it has been initiated by local communities for symbiotic relationship between foreign immigrants and native Japanese dwellers. But it can be regarded as a strategic ideology to control foreign immigrants as it targets mainly on Nikkeijin, and is usually concerned with the cultural aspect. Seen from a theoretical point of view, this concept can be seen as closed with liberal multiculturalism as opportunity equity, but far from corporative multiculturalism as outcome equity, and it is on the process transferring from the first stage of tolerance to the second stage of legislation of nondiscrimination, while being distant from the third stage of legislation paradigmization of recognition, and hence appears to be easily reverted to assimilationism.

The comparative molecular field analyses (CoMFA) models for the herbicidal activities against barnyardgrass (Echinochloa crus-galli) and rice plant (Orysa sativa L.) by the substituent (R) on the hexahydroisoindol-1-one ring in a series of new 2-(4-chloro-5-(2-chloroallyloxy)-2-fluorophenyl)-3-thioalkoxy-2,3,4,5,6,7-hexahydroisoindol-1-one derivatives were conducted and discussed for selectivity between both plants. The statistical results of the two best models (B2 & R7) showed the best predictability for the herbicidal activities based on the cross-validated value $q_2(r^2cv.=0.529{\sim}0.755)$ and none cross-validated value $({r^2}_{ncv.}=0.937{\sim}0.945)$, respectively. Based on the findings, the predictability and fitness of the model (B2) for barnyard grass was better than that of the model (R7) for rice plant. From the two models and contour maps, it is revealed that the novel selective character for herbicidal activity between the two plants depend on the electrostatic field and steric field for the substituent of ortho-positions on the S-phenyl group as R-substituent in hexahydroisoindol-1-one ring.

Fashion is one of the characteristics which represents the comtemporary sociocultural signifiant. A style that a certain stream of fashion brings is not just limited in fragmentary tendencies and fads. That can be a code to communicate and function as a medium in itself. Music has been displaying it's power to fashion while fashion has been exercising it's influence over the music. There is an inseparable relationship between music and fashion in terms of expressing our images of the world: fashion delivers them through visuality and music does it by sound. Both fashion and music are reflecting our society as well as they are influencing on sociocultural aspects generally. Whenever music has been changed new youth culture has been made and this culture has been expanded with forming some distinct fashion trends. The study focuses on identifying the relations between pop music and fashion styles which are occupying positions firmly on the bases of youth culture through analysing the relations between the fashion styles and music genres which are used in sub-culture groups to express their own identities and consciousness from a point of semiotics. In conclusion, subculture is the exit of their escaping from the compelling inconsistency cause by the condition of people's life and the way for them to solve through cultural sublimating for themselves. People come up with distinctive style of music and fashion to express their resistant signifie in their symbolic way. In addition, a particular music trend has much to do with a contemporary fashion style. In the relationship between music and fashion, there have been the subtle mechanism to boost and influence and some crucial similarity each other to signify inner values of the times. This study lets us realize that fashion is not only a popular style of clothes, hair, etc. at a particular time or place but also a medium to communicate and to guarantee polysemous identity by functioning as a flexible tool to exchange contemporary sociocultural meanings.

The present times is rapidly growing and changing. As both an industry and a social legislation are running after a generality, relatively the number of people who are out of it is gradually increasing. Those people are getting skeptical about their positions as well as their existences, so that a social deviant phenomenon has been continuously arising by themselves in public and private area. It is the Vandalism . People are often exposed to this Vandalism which is occurring around their life. Accordingly this study analyzed cause-and-effect Vandalism. As a means of impediment against the progressing Vandalism in design process, the study as been developed by approaching to an ergonomics design, a simple shape design (minimalism), a semantic design, a re-useful design. As a result, it comes to the fact that the Vandalism from the view of design is caused by a lack of ergonomics and user-interface, a failure of simple structure, a complication of excessive functions. Furthermore, it comes to the conclusion that industrial design is playing an important role in the contribution of social development, to create a design obstructing the vandalism will bring development of sound society.

The static stability of the otter board in relation to the angle of attack ($\alpha$) was studied analytically and experimentally from the moments of tensions and hydrodynamic force acting on it. Three flat plates of 0.5, 1.0, and 1.5 aspect ratios (λ) and four cambered plates of 5, 10, 15, and 20% camber ratios (CR) with the same aspect ratio (λ=1.5) were tested in a circulating water tank for measuring the hydrodynamic forces and moments relevant to the position of hydrodynamic center. And, center-of-pressure coefficients ($C_p$) and moment coefficients ($C_M$) of each plate as a function of the angle of attack were calculated for estimating the static stability from hydrodynamic forces. The obtained results are summarized as follows ； 1． When the angle of attack for otter board is changed from equilibrium for some reason, moments depending upon tensions of warp and sweep line always act in order to have the static stability, respectively. 2. Position of center-of-pressure of each flat plate moves from leading edge to center of plate with the increase of the angle of attack. It means that the moment of hydrodynamic force acting on flat plates also increases the static stability of plate. 3. With the increase of the angle of attack for cambered plates, the positions of center of-pressure move from trailing to leading edge, and then turn toward center of plate. As the camber ratios increase, the ranges of the angle of attack of the static un stability depending on moment of hydrodynamic force become wide.

This study examined the effects of the contact position and structure of the test probe on its signal transmission characteristics. The contact position in the operating of the test probe was considered and then divided into the plunger inner contact and barrel inlet contact. The high frequency performance of the test probes was investigated for both contact positions. The signal transmission characteristics of the test probes with the structures of double, single, and out-spring was also analyzed. The insertion and return losses were calculated using the HFSS and the characteristic impedance of the test probes was analyzed using a Q3D simulation. The insertion loss of the barrel inlet contact was smaller than that of the plunger inner contact. The contact position of the test probe may result in a change in the high frequency performance. The out-spring probe has better frequency characteristics at -1 dB insertion loss and -10 dB return loss. The double probe and single probe have the same characteristic impedance with $30.8{\Omega}$. On the other hand, the out-spring probe has an impedance of $47.1{\Omega}$. The out-spring probe is closer to $50{\Omega}$ than the other probes and then shows higher signal transmission characteristics. The out-spring probe has superior high-frequency characteristics and is expected to be suitable for high-speed applications.

The purpose of this study was to investigate the kinematic comparison between successful and failed trials of Lopez vault techniques in male gymnastics. The subject, an Olympic gold medalist, was YHS (age: 27 years, height: 1.6 m, and mass: 53 kg) and fourteen high speed motion capturing cameras were used for data collection. The 26 reflective sensors were attached on major anatomical positions and 15 segment-body model was used to calculate the kinematic variables. According to results, the contact duration of the spring-board for successful trial(ST) was longer and that of failed trial(FT) and the range of motion of knee joint for ST was greater than that of FT. The movement times during pre-flight between ST and FT were same, but the movement time of horse contact period for ST was shorter than that of FT. The ST showed a longer movement time during post-flight and the longer horizontal distance than those of FT. Conclusively, YHS needs to approach the horse with a higher position of the body and higher incidence angle, as well as make faster twist angular velocity in an attempt to achieve ST.

FCAW is used mainly in the welding of carbon steel and alloy steel because it can be welded in all positions and can obtain excellent quality at sites with variable working conditions. Recently, many studies in Korea have estimated the fatigue strength, residual stress, and deformation, and to develop a fillet welding process. On the other hand, there have been few studies of the mechanical properties based on the strength, macro and magnetic particle test results for fillet welding. This study shows the following results through fillet welding, macro testing and strength testing using SM490A (solid-structure rolled steel) for thick plates using SS400 (rolled steel) for the upper plate and FCAW. The hardness test, macro test and magnetic particle test were then conducted. The hardness tests showed that all result values were smaller than the KS B 0893 standard values of 350Hv. The macro-test showed that each type of welded part was in a normal organic state and that there were no internal errors, bubbles, or impurities on the front of the welded part. Therefore, there were no concerns about lamination. The magnetic particle examination showed no problems.
