Anterior knee pain is a major problem among adolescents and young adults especially those who participates in sports. The most common pathogenesis of anterior knee pain can arise from compression and shear forces in the patellofemoral joint. It is also caused by impingement of infrapatellar fat pad. Fat pad impingement can occur when the fat pad becomes swollen and inflamed due to a direct blow or chronic irritation. As a result, the bottom tip (or inferior pole) of the patella can pinch the fat pad. One of the many causes of swollen fat pad can be secondary to anterior cruciate ligament (ACL) injury. The aim of this study was to compare the infrapatellar fat pad volume in patients with acute ACL injury and a group of age-, gender-, and activity- matched controls with intact ligament. Axial magnetic resonance (MR) images have been performed on 32 patients with torn ACL and 40 control patients. The volume of the fat pad was measured digitally from MR image by using a 3d Reconstruction software, ellipsoidal approximation, and a MATLAB code. The results were compared between patients with torn ACL and control group. Patients with a torn ACL had a significantly larger fat pad than the controls (P=0.01). There was no significant difference between the methods used to measure the infrapatellar fat pad volume (P=0.83-0.87). Thus, lesions of the infrapatellar fat pad is often associated with ACL injury.

The purpose of this study is to make a comparative analyzation toward abstracted emotional properties appeared in the museum exhibition spaces designed by the three masters of the modern architecture;Frank Lloyd Wright, Le Corbusier and Mies van der Rohe. In addition, this study will also aim to inquire into how the emotional properties have affected the third generation architects. It is especially expected that the 'emotional tendency' emerging in various fields of the present time can serve as useful information through the analysis of emotional design properties appeared in the exhibition space which is directly linked with the human lives. In order to achieve the purpose of the study, in New York by Wright, in Tokyo by Le Corbusier and in Berlin by Mies Van der Rohe were selected. As for the analyzation methodology to be adopted for deriving the aiming points at the emotional design, five criteria of analyzation have been established in order to understand the properties of the emotional area: they are (1) spatial affordance, (2) human congeniality, (3) emotional factors of the area, (4) constitution of the area and (5) expressive division of the area. Using these criteria, this study will reveal what are some of the emotional characteristics shown in each museums and its analytical result will be useful to apply to future museum design. It is especially expected that the 'emotional tendency' emerging in various fields of the present time can serve as useful information through the analysis of emotional design properties appeared in the exhibition space of design which is directly linked with the human behavior.

Frank Lloyd Wright(1867-1959) had the confident concept that architecture should be at home in nature. His architecture was meant to bear an intimate relation to the earth and the sky, and should look as though it began there at the ground and contrasted with the sky. In handling all the details of house design elements, his efforts for being married to the ground was to conceive the void of the sky. This study is to research his thinking process and its development to the earth and the sky, and to analyze how such thought could reflect his houses. The mass of house are divided into three parts such as the foundation or base, body, and roof. These parts are respectively related to the earth and the sky. This study goes on regarding them as an analytical framework. The subjects of study are the Prairie houses in the early 20th century and the Usonian houses after 1930's. As results of this study, the earlier foundation as a platform appeared as a base and water table, and a strong baseline pressed the structures into the soil in the Prairie houses. The direct contact of wood and brick to ground were dominant details after Wiley house(1934). The base was almost invisible to the eye in the Usonian houses. Secondly, the pierlike shapes and delicate friezes of walls were anchored to the ground, and horizontal bands as trims or copings also got close to the earth. These characters had disappeared after the Allen house(1917), all components including exterior walls had been unified with the grid patterns in the Usonian houses. Thirdly, the overhanging cantilever roof had got to the earthbound by the reflection of shadow as well as their evident horizontal. He lowered the roof, lengthened and brought it closer to the ground. In this way, Frank Lloyd Wright intended his houses to be at home in nature. And also he tried to bind the houses to the earth and contrasted them with the sky. The houses would perform their highest function in relation to the earth and sky.

Wright wants to create a democratic egalitarian society through his real utopias project where everyone is guaranteed the access to material and social means or opportunities for human flourishing and where democracy is maximized. However, he does not provide a convincing rationale for his democratic egalitarianism. This paper shows that the basic income derived from the equal rights to commons can be a convincing basis for his democratic egalitarianism. This paper then restructures his real utopias project into a more consistent system based on the basic income derived from commons. It also argues that Wright's vision of Real Utopias overlaps with the vision of a 'sharing society', a 'society based on democratically managed and controlled commons and basic income'. This article therefore argues that the Real Utopias Project and the basic income project can on the one hand develop based on these overlaps and correlations and on the other, based on each other's results.

A remarkably large number of integral formulas involving a variety of special functions have been developed by many authors. Also many integral formulas involving various Bessel functions have been presented. Very recently, Choi and Agarwal derived two generalized integral formulas associated with the Bessel function $J_{\nu}(z)$ of the first kind, which are expressed in terms of the generalized (Wright) hypergeometric functions. In the present sequel to Choi and Agarwal's work, here, in this paper, we establish two new integral formulas involving the generalized Bessel functions, which are also expressed in terms of the generalized (Wright) hypergeometric functions. Some interesting special cases of our two main results are presented. We also point out that the results presented here, being of general character, are easily reducible to yield many diverse new and known integral formulas involving simpler functions.

ZnO nanotips, grown on c-$Al_2O_3$ and quartz, were implanted variously with 200 keV Fe or Mn ions to a dose level of $5{\times}10^{16}cm^{-2}$. The magnetic properties of these samples were measured using a superconducting quantum interference device (SQUID) magnetometer. Fe-implanted ZnO nanotips grown on c-$Al_2O_3$ showed a coercive field width of 209 Oe and a remanent field of 12% of the saturation magnetization ($2.3{\times}10^{-5}emu$) at 300K for a sample annealed at $700^{\circ}C$ for 20 minutes. The field-cooled and the zero-field-cooled magnetization measurements also showed evidence of ferromagnetism in this sample with an estimated Curie temperature of around 350 K. The Mn-implanted ZnO nanotips grown on c-$Al_2O_3$ showed superparamagnetism resulting from the dominance of a spin-glass phase. The ZnO nanotips grown on quartz and implanted with Fe or Mn showed signs of ferromagnetism, but neither was consistent.

The Fallingwater, one of Wright's best designs, is known as a good example of "Organic Architecture". Its landscape characteristics are harmonious relationship between architecture and landscape, adaptable siting, composition of spatial and visual structure, floating spaceness, interlocking of water and house, dramatic approach, and vernacular material use. This characteristics had begun from the Prairie architecture, but also had influenced by the culture and art of the Far East. He was open to foreign cultures. Staying in Japan for years, he had travelled China, too. In this process, he might be exposed to Korean art and culture which were under Japan at that time. Comparing the front image of the Songkwang Temple to that of the Fallingwater, their compositions between architecture, water, and landscape are so similar to each other. They are also close to each other in terms of spatial structure. Therefore the landscape characteristics found in the Fallingwater design are more similar to Korean landscape architectural characteristics than Japanese ones. Therefore we are going to suggest the hypothesis that Wright is influenced by Korean landscape design in the design of the Fallingwater. Considering his impact upon the design world, it will be significant if the concept of Korean traditional landscape design is placed behind his design of the great architecture.hitecture.

Connector's role between components is very important in the CBD(Component Based Development). The most connector has process ADL based rrethod was choosing FIFO method by component request. But in case many component's with various characteristics request It is difficult that this method operate efficiently, In this research, I did design and implement priority connector considering component's processing time, Also, I used Wright architecture for formal specification. Application result of proposed connector was spend more 388ms compares with existent FIFO method in total processing time. But this method could handle preferentially from components that have short processing time. Also, in case of component's waiting time in connector, existent FIFO method is 23323,1 ms and proposal method is 12731.27ms, So, proposal method could reduce waiting time for component process.
