This paper provides thoretical research and previous empirical evidence on the Implicit Tax. Results of previous empirical studies are consistent with the predictions of the Implicit. Tax hypothesis and are stastically significant inverse relation between tax subsidy(PTTSE) and pre-tax returen(PTROE). But the empirical relation is weaker than predicted for a perfectly competitive and frictionless market, which is due to presence of market frictions or systematic measurement error. We can know that previous studies on the tax burden of corporate that measured the varioation fo Explict Tax only have not means. As a result, tax burden of corporate is sum of Explict Tax and Implicit Tax, When both Explict Tax and Implict Tax are considered, horizontal inequity of tax burden disappear. So we can appreciate efficiency of tax strategy. Existence of Implict Tax resulted from the tax subsidy means efficient in the application of tax strategy.
Review of Battery Charger for V2G Application
Yu Gui,Long Yong 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.8
At present, V2G(vehicle to grid) technique is received more and more attention due to developing of renewable energy sources. So, development process of EV(electric vehicle) technology is introduced in this paper and relative difficulties in V2G is analyzed. The main difficulties including the service life of battery, control strategy of current and the EVs paralleling into the grid. Battery charger is one of the key technologies of V2G.The charger consist of a filter, an AC/DC converter for grid interface and multiple bidirectional DC/DC converters for EV battery management, and a direct-current control mechanism is employed for ac system bus voltage and dc-link voltage control. Simulation results show that the AC/DC converter and the DC/DC converters have the function of electric power flowing with two-ways. Finally it points out the development direction of V2G technology.

Rabies remains an important worldwide health problem. Newcastle disease virus (NDV) was developed as a vaccine vector in animals by using a reverse genetics approach. Previously, our group generated a recombinant NDV (LaSota strain) expressing the complete rabies virus G protein (RVG), named rL-RVG. In this study, we constructed the variant rL-RVGTM, which expresses a chimeric rabies virus G protein (RVGTM) containing the ectodomain of RVG and the transmembrane domain (TM) and a cytoplasmic tail (CT) from the NDV fusion glycoprotein to study the function of RVG’s TM and CT. The RVGTM did not detectably incorporate into NDV virions, though it was abundantly expressed at the surface of infected BHK-21 cells. Both rL-RVG and rL-RVGTM induced similar levels of NDV virus-neutralizing antibody (VNA) after initial and secondary vaccination in mice, whereas rabies VNA induction by rL-RVGTM was markedly lower than that induced by rL-RVG. Though rL-RVG could spread from cell to cell like that in rabies virus, rL-RVGTM lost this ability and spread in a manner similar to the parental NDV. Our data suggest that the TM and CT of RVG are essential for its incorporation into NDV virions and for spreading of the recombinant virus from the initially infected cells to surrounding cells.
On the historicization of the mythical legend of Huang Di in China
iao. Gui-yu 조선대학교 국제문화연구원 2012 국제문화연구 Vol.5 No.1
一般认为黄帝是中国古代第一次最激烈的涿鹿大战之后成为中华民族第一 始祖的英雄人物。不过中国史书中还记载在战争英雄时期以前有关‘黄帝四面’ 的远古神话的片断。本论文着重分析有关黄帝的远古神话原型以及逐渐变成 历史人物的过程,探讨上古时期选民的原始思维的特点以及作为中华民族始 祖黄帝的历史上留下的各种意象。作为第一始祖的黄帝最近在部分地区又变 成炎黄蚩三始祖之一。相信黄帝神话的历史化考察有益于中华文明起源的新 的探讨。

Introduction: This study assessed the relationship of E-cadherin mRNA and protein expression with the diagnosis of lung cancer with the aim of providing an auxiliary diagnostic method. Methods: Semi-quantitative nested RT-PCR and western blotting were applied to detect E-cadherin mRNA transcripts and protein, respectively, in 30 cases of diagnostic lung cancer, 30 cases of clinically suspected patients with lung cancer and 30 cases of other disease. Immunohistochemical staining was also used to detect E-cadherin. Results: Remarkably decreased levels of relative E-cadherin mRNA value and increased E-cadherin protein negativity were observed in probable lung cancer, when compared with possible lung cancer and others. With a threshold of 1.45, relative E-cadherin mRNA value showed a sensitivity of 90% and a specifity of 83% for the diagnosis of lung cancer. The combination of decreased relative E-cadherin mRNA value and negative E-cadherin protein increased the specificity and sensitivity. Conclusion: These data suggest that Chinese patients with diagnostic lung cancer have similar decreased levels of relative E-cadherin mRNA and E-cadherin protein value in the lung cancer tissues as in lung cancer patients in other countries. Measurement of relative E-cadherin mRNA and protein values in lung cancer tissues has potential for lung cancer diagnosis.
