To develop a new anti-inflammation agent for cosmetics, we investigated the anti-inflammatory activity of Fallopia sachalinensis RonseDecr. fruit extracts (FSR). FSR inhibited the pre-inflammatory cytokines ($1L-1{\beta}$, IL-6, TNF-${\alpha}$) and reduced NO production of RAW 264.7 macrophage cells in a dose-dependent manner and decreased the activity to about 51% at a concentration of $100{\mu}g/mL$. FSR suppressed not only the mRNA expression of iNOS and COX-2, but also the protein expression of iNOS and COX-2 in macrophage. The results suggested that FSR has considerable potential as a cosmetics ingredient with an anti-inflammatory effect.

Let G be an abelian topological group and $x_{ij} \in G$ for all $i, j \in N$ such that the series $\sum_{j=i}^{\infty} x_{ij}$ is subseries convergent for each i.

The purpose of this study was to investigate the improvement of muscle strength and gait ability of paralyzed lower extremity through convergent stimulation of tDCS(transcranial direct current stimulation) during mirror therapy with resistance exercise in chronic stroke patients. 12 patients with stroke were randomly assigned and divided into groupI(n=6) and groupII(n=6). GroupI provided NDT(neurodevelopmental treatment) and mirror therapy with sham tDCS, and groupII provided NDT and mirror therapy with tDCS. Each convergent stimulation was conducted 5 times a week, 30 minutes per session for a total of 4 weeks. All evaluation was conducted before intervention and performed after 4 weeks. Lower extremity strength showed a significant improvement in groupII compared to groupI(p<.05), and in comparison between groups by variance, significant difference in the quadriceps(p<.01) and tibialis anterior(p<.01). Gait ability showed a significant improvement in both groupI(p<.05) and groupII(p<.05), and significant difference in comparison between groups by variance(p<.01). In conclusion, mirror therapy with tDCS convergent stimulation had a positive improvement effect on paralyzed lower extremity to strength and gait ability through the overlapping interaction.

This paper proposes a new quickly convergent pattern search quasi-Newton algorithm that employs the multi-step version of the Symmetric Rank One (SRI). The new algorithm works on the factorizations of the inverse Hessian approximations to make available a sequence of convergent positive bases required by the pattern search process. The algorithm, in principle, resembles that developed in [1] with multi-step methods dominating the dervation and with numerical improvements incurred, as shown by the numerical results presented herein.

We demonstrate a fabrication of an atomically controlled single-crystal heart-shaped nanostructure using a convergent electron beam in a scanning transmission electron microscope. The delicately controlled e-beam enable epitaxial crystallization of perovskite oxide LaAlO₃ grown out of the relative conductive interface (i.e. 2 dimensional electron gas) between amorphous LaAlO₃/crystalline SrTiO₃.

The idea of C^*-algebra valued metric spaces was given by Ma, Jiang and Sun. In this paper we have studied the ideas of I-Cauchy and I^*-Cauchy sequences and their properties in such spaces and also we give the idea of C^*-algebra valued normed spaces.

I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.

In this paper, a unified method to construct a quadratically convergent algorithm with one dimensional search schemes is described. With this method, a generalized algorithm is derived. As it's particular cases, three quadratically convergent algorithms are performed. They are the rank-one algorithm (Algorithm I), projection algorithm (Algorithm II) and the Fletcher-Reeves algorithm (Algorithm III). As one-dimensional search schemes, the golden-ratio method and dichotomous search are used. Additionally, their computer programming is developed for actual application. The use of this program is provided with the explanation of how to use it, the illustrative examples that are both quadratic and nonquadratic problems and their output. Finally, from the computer output, each algorithm was analyzed from the standpoint of efficiency for performance.

In order to achieve high capacity and reliable link quality of the overlay convergent networks with the cognitive networking based on the advanced capability of the mobile terminal, a Distributed Wireless Communication System (DWCS) can provide the capability of enhancing the link quality. This paper has considered virtual cell: the Dual Virtual Cell (DVC), and also proposes DVC employment strategy based on radio resource monitering. The considered system constructs DVC for multi-user high-rate data transmission, and the DWCS system exploits space-time trellis codes i.e., STTC to improve a spectral efficiency. The effects of imperfect CSI(channel state information) on the system performance has also been investigated.
