Since R&D (Research and Development) of small companies is becoming more and more important, and government R&D grants are still increasing. This study aims to investigate the factors influencing R&D performance of small companies and necessary capabilities of them. Based on empirical study of 3,636 small companies which participated and completed government R&D grant project, technology innovation capability and technology commercializing capability of small companies are positively related with organizational competences, with moderating effects of entrepreneurship. In addition, their R&D capabilities are not significantly related with R&D commercializing performance directly, but mediated with organizational competences. The results of study suggest implications of measuring the R&D performance of small companies and government support policy with the importance of organizational competences as an intermediate variable of R&D performances.

Let D be an integral domain, X be an indeterminate over D, and $N_v=\{f{\in}D[X]{\mid}(A_f)_v=D\}$. In this paper, we introduce the concept of t-locally divided domains, and we then prove that $D[X]_{N_v}$ is a locally divided domain if and only if D is a t-locally divided UMT-domain, if and only if D[X] is a t-locally divided domain.

A new tannin, polygagallin, related to acertannin, is isolated from air-dried leaves of Acer ginnala Max. as prismatic crystals with 1/2 H$_{2}$O per mole, m.p.154-155.deg. and [.alpha.]$_{D}$$^{29}$ +43.79.deg. C. Polygagllin gives hexaacetate, m.p.164.5.deg. C, [.alpha.]$_{D}$$^{28}$ +42.deg. C, on treating with anhydroacetic acid and on treating with diazomethane, gives trimethyl ether, m.p.176.deg. C, [.alpha.]$_{D}$$^{22}$ +53.43, which yields triacetate, m.p.160.5.deg. C, [.alpha.]$_{D}$$^{22}$ + 132.5.deg. C, on acetylation and is not attacked by periodate. On hydrolysis, trimethoxypolygagallin yields one mole of polygalitol and that of trimethoxygallic acid. By the above results polygalallin has been established as 3-galloylpolygalito.ygalito.galallin has been established as 3-galloylpolygalito.

Dumortiera hirsuta (Sw.) Nees (Dumortieraceae) is a thallose liverwort distributed in tropics and subtropics. It is the only species in family Dumortieraceae, which is the second basal family in order Marchantiales. D. hirsuta is characterized by hairy receptacles and lacking air chamber. The complete chloroplast genome of D. hirsuta was successfully rescued from raw reads generated by HiSeq4000. Its total length is 122,050 bp consisting of four regions: large single copy (LSC) region (81,697 bp), small single copy (SSC) region (20,061 bp), and two inverted repeats (IRs; 10,146 bp per each). It contained 129 genes (84 coding DNA sequence (CDS), eight rRNAs, and 37 tRNAs); 18 genes including four rRNAs, and five tRNAs are duplicated in the IR regions. The overall GC content of D. hirsuta is 28.7%, which is almost same to that of Marchantia paleacea. Phylogenetic tree based on all genes from whole chloroplast genomes will provides phylogenetic position of D. hirstua. This sequence will be an fundamental resources for further researches of order Marchantiales.

Let $g(n,\;l_1,\;l_2,\;d,\;t,\;q)$ be the number of general4-regular graphs on n labelled vertices with $l_1+2l_2$ loops, d double edges, t triple edges and q quartet edges. We use inclusion and exclusion with five types of properties to determine the asymptotic behavior of $g(n,\;l_1,\;l_2,\;d,\;t,\;q)$ and hence that of g(2n), the total number of general 4-regular graphs where $l_1,\;l_2,\;d,\;t\;and\;q\;=\;o(\sqrt{n})$, respectively. We show that almost all general 4-regular graphs are 2-connected. Moreover, we determine the asymptotic numbers of general 4-regular graphs with given connectivities.
