Null designs form a vector space and there are only finite number of minimal null designs(up to scalar multiple), hence it is natural to look at the convex polytopes of minimal null designs. For example, when t = 0, k = 1, the convex polytope of minimal null designs is the polytope of roofs of type An. In this article, we look at the convex polytopes of minimal null designs and find many general properties on the vertices, edges, dimension, and some structural properties that might help to understand the structure of polytopes for big n, t through the structure of smaller n, t.

The following contents are the results from the examination of unisex fetishism minimal and active which are Mods look. Unisex-becasue of the changing in musician and the role of sex Mods girl adopted much from men's clothing. The unisex mods look expressed in the 1990s is not the expression confronting the estab-lished value and the confusion of sex as it did in the '60s but possibly the appearance of a fashion trend. Fetishism-in the '60s the Mods look changed mens clothing into more wonman-like clothing which expressed their internal and external values of thinking. this fetishism phenomenon is also strongly expressed among the in the 1990s. This gives a future-orientid feeling by expressing with a modern sense the 60's fetish dress which used woman-like silhouettes bright and stretch fabric colorful and vivid tone. Minimal-The 60's Mods put on mini skirts called the revolution of length as a mode of re-sistance and mininmal dress as a way of ex-pressing the liberation of body and the con-sciousness of beauty. Minimal is reflected well on slim and fit jackets and pants and short and fit pants etc. mods look in the '90s also consists of the general trend of slim and fit silhouette. Active-Mods that reject the value of estab-lished generation in the 60s showed a sporty and casual trend on fashion. Mods works around clubs wore polo shirts and cadigan and Mods enjoys scooter often wore anorak parkas This active style of Mods approched to the young' casual with freshness expressing newly in the '90s polo shirts took a seat as an item of street fashion especially in the beginning of 1996. Mods in the 1960s shows well a fashion flow of the age as a street fashion which expresses the mental world reflected in politics econo-mics society and culture within the people of the age. These Mods looks revived in the early 1990's awaken an importance of the culture of the young as the cultural qualities included in Mods of the past life and this fashion trend expected to take a part as a symbol of fashion culture.

Purpose: To evaluate the clinical effects of using anatomical bony landmarks (Parsons' knob and the medial intercondylar ridge) and minimal ablation of the tibial footprint to improve knee anterior instability and synovial graft coverage after double-bundle anterior cruciate ligament reconstruction. Materials and Methods: We performed a retrospective comparison of outcomes between patients who underwent reconstruction with minimal ablation of the tibial footprint, using an anatomical tibial bony landmark technique, and those who underwent reconstruction with wide ablation of the tibial footprint. Differences between the two groups were evaluated using second-look arthroscopy, radiological assessment of the tunnel position, postoperative anterior knee joint laxity, and clinical outcomes. Results: Use of the anatomical reference and minimal ablation of the tibial footprint resulted in a more anterior positioning of the tibial tunnel, with greater synovial coverage of the graft postoperatively (p=0.01), and improved anterior stability of the knee on second-look arthroscopy. Both groups had comparable clinical outcomes. Conclusions: Use of anatomical tibial bony landmarks that resulted in a more anteromedial tibial tunnel position improved anterior knee laxity, and minimal ablation improved synovial coverage of the graft; however, it did not significantly improve subjective and functional short-term outcomes.

The purpose of this study is to investigate the fashion reflecting the aesthetic consciousness of a generation and age spirit and to study Mods-Look aesthetically by analyzing how Mods-Look expressed on the fashion magazines(Collezioni Donna) from 2001 to 2006 developed into a new form. 1960's Mods-Look appeared in the well known collections such as New York, Paris, Milan in the form of crossover or with a changed style. Especially after 2000's, in addition to the British fashion, even a new word Mods Story was created to prominently express the free style of the Mods spirit. The expressive characteristics represent 1) minimal style, 2) sports casual style, 3) vintage style, 4) dandy & androgynous style. In conclusion, Mods-Look in 21st fashion used to be street fashion started from minority subculture after world war II, but now suit of that time, geometrical pattern and sensibility are becoming design sources for the various fashion market from high fashion to sports look. Therefore, as young people are becoming the center of society in new millenium, sensibility of that time will be reinterpreted to design and Mods-Look will not be limited to subculture but reflected in design development fulfilling people's taste and new future fashion sense by compromising the past and new trend.

The purpose of this study is to observe the meaning of Minimalism and the characteristics in modem fashion design. The Minimalism appeared in 1960's has affect on fashion design which are simple miniskirt or Courrage look of those days. It leads a fashion system to the simple style goes with the life style of modem persons although the characteristics are somewhat different the styles in 1960's with those of 1990's. Minimal style is not just simple style but abbriviate expression constrained at the minimum. The styles appeared to be an undecorated simple line which are a sleeveless onepiece, a simple suit with no pocket and no collar and narrow shoulder. Colors are monochrome coordination and pursue a simplicity which is monotone variation. Patterns also appeared to be a geometric or abstract pattern for example check and stripe, which intend to minimum expression. Matirials are hightech glossy coating textures which have a futuristic image. In conclusion, the Minimalism in 1990's appeared to be a post-minimalism associated with postmodernism and a hightech-minimal under the technology development.

Following to current interior design that becoming more varied and composite, minimal tendency has also been changed. Furthermore, according to the lapse of time, minimalism, a space design, has been developed in a new look among such complex trends. Therefore, in this study, changes of tendency into a style of minimalism and characteristics thereof shown in interior design amid current of times were carefully reviewed, and local and foreign artists together with their works were investigated and analyzed having focused on the inclination of minimalism displayed in interiors of commercial spaces, especially before or after 2000s by dividing them into distinctive features in connection with space, material and type. It is thought that the interior space under the concept of minimalism will be changed and developed further in a variety of shapes to suit the environments in the current era getting rid of simple physical characteristics.

In each step of the quasi-minimal residual (QMR) method which uses a look-ahead variant of the nonsymmetric Lanczos process to generate basis vectors for the Krylov subspaces induced by A, it is necessary to decide whether to construct the Lanczos vectors $v_{n+l}\;and\;w{n+l}$ as regular or inner vectors. For a regular step it is necessary that $D_k\;=\;W^{T}_{k}V_{k}$ is nonsingular. Therefore, in the floating-point arithmetic, the smallest singular value of matrix $D_k$, ${\sigma}_min(D_k)$, is computed and an inner step is performed if $\sigma_{min}(D_k)<{\epsilon}$, where $\epsilon$ is a suitably chosen tolerance. In practice it is absolutely impossible to choose correctly the value of the tolerance $\epsilon$. The subject of this paper is to show how discrete stochastic arithmetic remedies the problem of this tolerance, as well as the problem of the other tolerances which are needed in the other checks of the QMR method with the estimation of the accuracy of some intermediate results. Numerical examples are used to show the good numerical properties.
