Emerging evidence suggests that gap formation and opening of the endothelial junctions during leukocyte extravasation is actively controlled to maintain the integrity of the vascular barrier. While the role for endothelial cells to this process has been well defined, it is not clear whether leukocytes are also actively contributing to endothelial barrier function. We have recently showed that extravasating leukocytes deposit microparticles on the subendothelium during the late stages of extravasation, which is LFA-1 dependent. Using multiphotonintravital microscopy (MP-IVM) of mouse cremaster muscle vessels in the current work, we show that microparticle formation and deposition maintains the integrity of the microvascular barrier during leukocyte extravasation. Inhibition of neutrophil-derived microparticle formation resulted in dramatically increased vascular leakage. These findings suggest that deposition of microparticles during neutrophil extravasation is essential for maintaining endothelial barrier function and may result in temporal difference between neutrophil extravasation and an increase in vascular leakage.

Drawing on Fiengo and May(1995)’s claim that the conditions on bound variable anaphora are not coextensive with those on sloppy identity, I propose an account for the question of why only the monomorphemic reflexive caki, but not the pronoun ku in Korean can take a quantified expression as its antecedent, whereas both can be read sloppily under ellipsis. We will also see how Fiengo and May’s Dependency Theory together with my pragmatic reasoning explains some intriguing phenomena involving phrases with mace ‘even’ and man ‘only’ operators.

Invariant Imbedding Theory of Wave Propagation in Stratified Complex Media
Kihong Kim,Hanjo Lim 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.5
We review a generalized version of the invariant imbedding theory of wave propagation, which has been developed by us recently, in various kinds of stratified media. The main idea of the method is to transform the boundary value problem of the original wave equation into an equivalent initial value problem of coupled ordinary dierential equations. This allows an exact and very efficient numerical calculation of the re ection and the transmission coefficients and of the wave functions inside inhomogeneous media. We demonstrate the advantages of the method over other theoretical methods by applying it to several interesting cases. In the rst case, we apply the method to the propagation of electromagnetic waves in random dielectric media. Next, we give a short discussion of the application of our method to wave propagation in nonlinear inhomogeneous media. Finally, we discuss the generalization of the invariant imbedding method to cases where several coupled waves propagate in arbitrarily-inhomogeneous stratied media and apply it to electromagnetic wave propagation in layered chiral media.

Exact Calculation of the Optical Properties of One-Dimensional Nonlinear Photonic Crystals
Kihong Kim,D. K. Phung,F. Rotermund,H. Lim 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.5
We develop a new version of the invariant imbedding theory of wave propagation in arbitrarily-inhomogeneous stratified media made of nonlinear materials. Using this theory, we study electromagnetic wave propagation in one-dimensional nonlinear photonic crystals with and without a defect layer. The invariant imbedding theory allows us to calculate various wave propagation characteristics very efficiently in a numerically exact manner. We calculate the transmission spectra and the electric field distribution inside nonlinear photonic crystals. We find that the electric field inside the defect layer is strongly enhanced. We also observe strong optical bistability near the defect frequency.

Nowadays demand for automatic manufacturing system is increasing. Petri Net is a methodology for modeling and analysing discrete event systems by which most manufaturing systems are modeled. Petri Net makes it possible to find the optimal manufacturing procedure and dead lock state in advance. In this study, an LCD manufacturing process has been modeled and analyzed using Petri Net. Two manufacturing schemes have been analyzed and their performance has been compared, using Petri Net.

<P> We consider the propagation of p-polarized electromagnetic waves obliquely incident on stratified random dielectric media. Using the invariant imbedding method generalized to random media and applying the random phase approximation, we derive a simple analytical expression of the localization length and calculate the disorder-averaged reflectance and transmittance and the fluctuations of the localization length and the reflectance as functions of the incident angle. We also calculate the disorder-averaged intensity profile of the magnetic field inside the random medium. We find that within the random phase approximation, the p wave can be delocalized and transmitted completely at a certain critical incident angle, which is bigger than the Brewster angle in the uniform case.</P>
