In this paper, "a conceptual model of Reconnaissance-Strike-Logistics Complex(RSLC) in future warfare" is proposed. Basic idea of the RSLC model is to combine logistics and the pre-existing Reconnaissance-Strike Complex(RSC) through a C4 network system. That is, the RSLC model consists of reconnaissance, strike, logistics, and C4 network systems. The C4 network system creates new combat power by integrating all the other systems. The RSLC model generates three conceptual complex circles; the RSC, the SLC(Strke-Logistics Complex), and the RSLC circles. The RSC circles describes direct combat behaviors in the battlefield. On the other hand, the SLC circle indicates combat sustainment capabilities. The RSLC circle including the RSC and the SLC circles, can present a more complete combat process. There are two key advantages of the RSLC model. First of all, logistics is considered one of key combat components to form IDA(Information-Decision-Action) cycle for combat decision-making process more completely. Secondly, the capabilities of battlefield awareness which reconnaissance and war-net systems provide, can be applied not only to the strike system in the RSC circle, but also to the logistics system in the SLC circle. Thus, the RSLC model can maximize combat synergy effects by integrating the RSC and the SLC. With a similar logic, this paper develops "A Revised System of Systems with Logistics (RSSL)" which combines "A New system of Systems" and logistics. These tow models proposed here help explain several issues such as logistics environment in future warfare, MOE(Measure of Effectiveness( on logistics performance, and COA(Course of Actions) for decreasing mass and increasing velocity. In particular, velocity in logistics is emphasized.

Teenage girls under the influence of the physical changes due to the rapid physical development and appearance are interested. 200 parts were used for the statistical analysis of this research against the common excitation high school student positioned in Seoul. First, there was lots of the girl student managing the appearance due to the psychological satisfaction. And the girl student without the friend of the opposite sex managed the appearance at the psychological satisfaction. Because to be more important, thing including the studying, and etc. was the priority the girl student who doesn't the appearance management did not do the appearance management. Second, the factor found out over one month allowance 50,000 circle to be the very important factor through the beauty action high of the high beauty product concern degree and girl student action of the beauty product concern degree and girl student where there is the friend of the opposite sex. Third, the more the concern degree about the beauty product was high as the concern degree about the beauty was high, the girl student in high school could know that beauty action was high as the concern degree about the multi function beauty product was high.

We prove a Guillemin-Sternberg geometric quantization formula for circle action on odd dimensional $spin^c$-manifolds. We prove two Kostant type formulas in this case. As a corollary, we get a cutting formula for the odd spinc quantization.

Aspirin is one of the oldest synthetic drugs and remains the most widely used medical agent. It is a household remedy effective in treating such common ailments as headache, minor muscular pain and fever. Aspirin is the drug choice for rheumatic fever and arthritis which some five million Americans suffer. Lately it has been established by double-blind and randomized clinical studies that regular aspirin intake reduces the incidence of mild strokes and heart attackes.

The $S^1$-Eule characteristics of X is defined by $\bar{\chi}_{S^1}(X)\;{\in}\;HH_1(ZG)$, where G is the fundamental group of connected finite $S^1$-compact manifold or connected finite $S^1$-finite complex X and $HH_1$ is the first Hochsch ild homology group functor. The purpose of this paper is to find several cases which the $S^1$-Euler characteristic has a homotopic invariant.

The purpose of this study analyzes the basic elements of film acting based on Stanislavsky Circles of Attention. This research also demonstrates the basic elements on how to become a good film actor. I attempt to interpret Stanislavsky Circles of Attention, in order to adapt the size of camera shots and the location of microphones. This Circles of Attention is an effective method utilized for actors to help them understand and be absorbed in the work of art both in film and stage. It is useful for building a character in realism drama as well as in film. I believe Stanislavsky Circles of Attention is certainly the most advanced acting style in film because it proposes the importance of physical action for actors.

This study suggests an algorithm for tooth profile generation of free from curve involute gear, a special gear of which the pitch line is a free curve instead of a circular one. For the first, a methodology for calculation of the tooth curve is developed and formulated Then the formulated algorithm, is programmed for manufacturing and verified by computer graphics. Next the calculated results as changed in to NC codes to apply to wire electric discharge machine(WEDM). Finally, the machined gear is examined in engagement with a standard involute gear.

For the replacement of deteriorated concrete decks or wider-span slab, composite slab could be very attactive due to higher stiffness and strength. Based on the previous research, a modified I-beam composite hollow slab was suggested. In order to investigate the static flexural behavior of the proposed composite slab and to suggest its flexural design method, experiments were performed. Judging from the tests, a composite slab with I-beam having a semi-circle hole showed better structural performance. The effect of web details on the flexural stiffness was negligible. Flexural stiffness, ultimate strength, and ductility of the composite slabs were significantly greater than the RC slab due to composite action. While the failure of the RC slab was punching shear failure, the composite hollow slab showed flexural cracking and failure by yielding of the I-beams and crushing of concrete. Therefore, the current one-way design concept is appropriate for the design of I-beam composite hollow slab.

We classify minimal surfaces in ${\mathbb{S}}^3$ which are foliated by circles and ruled constant mean curvature (cmc) surfaces in ${\mathbb{S}}^3$. First we show that minimal surfaces in ${\mathbb{S}}^3$ which are foliated by circles are either ruled (that is, foliated by geodesics) or rotationally symmetric (that is, invariant under an isometric ${\mathbb{S}}^1$-action which fixes a geodesic). Secondly, we show that, locally, there is only one ruled cmc surface in ${\mathbb{S}}^3$ up to isometry for each nonnegative mean curvature. We give a parametrization of the ruled cmc surface in ${\mathbb{S}}^3$(cf. Theorem 3).
