  • A new zero-voltage-switching (ZVS) push-pull pulse-width modulation (PWM) converter is proposed in this paper. The wide ZVS condition for all of the switches is obtained by utilizing the energy stored in the output inductor and magnetizing inductance. As a result, the switching losses can be dramatically reduced. A simple auxiliary circuit including two small diodes and one capacitor is added at the secondary side of a high frequency (HF) transformer to reset the primary current during the circulating stage and to clamp the voltage spike across the rectifier diodes, which enables the use of low-voltage and low-cost diodes to reduce the conducting and reverse recovery losses. In addition, there are no active devices or resistors in the auxiliary circuit, which can be realized easily. A detailed steady operation analysis, characteristics, design considerations, experimental results and a loss breakdown are presented for the proposed converter. A 500 W prototype has been constructed to verify the effectiveness of the proposed concept.

  • To assess inhibition mechanisms of a Phellinus igniarius (PI) extract on cancer, C57BL/6 mice were orally treated with PI extractive after or before implanting H22 (hepatocellular carcinoma ) or B16 (melanoma) cells. Mice were orally gavaged with different doses of PI for 36 days 24h after introduction of H22 or B16 cells. Mice in another group were orally treated as above daily for 42 days and implanted with H22 cells on day 7. Then the T lymphocyte, antibody, cytokine, LAK, NK cell activity in spleen, tumor cell apoptosis status and tumor inhibition in related organs, as well as the expression of iNOS and PCNA in tumor tissue were examined. The PI extract could improve animal immunity as well as inhibit cancer cell growth and metastasis with a dose-response relationship. Notably, PI's regulation with the two kinds of tumor appeared to occur in different ways, since the antibody profile and tumor metastasis demonstrated variation between animals implanted with hepatocellular carcinoma and melanoma cells.

  • After reform and openness action, china has been recorded high rate of increasing in export and continuous economic growth. Also their role in the international economy has been rise. The major reason of these incredible growth of China is the openness by a trade, after all the economic growth of China is evaluated an export-led growth. But, some insist that the growth of China has been accomplished by a domestic-based economy not but an export-led economy. For verification of former insists, using a yearly data, China exports and GDP, from 1979 to 2007 and performs time-series to examine an existence of causality between China's regional exports and GDP. As result of analysis, GDP and exports have two-way causality significantly when not considering region case. After the direction of Chinese reform, the east region has a strong significant relation, which support that export-led growth. While, middle and west region has weak causality between exports and GDP.

  • 선박은 물을 떠날 수 없고, 항로의 자연환경에 따라 항행해야 하기 때문에 항행하는 해역환경에 의하여 선박의 특성이 결정된다. 중국의 남방과 북방의 해역은 상이한 특징을 가지고 있다. 즉 남방의 해역은 수심이 갚고, 북방의 해역은 수심이 얕다. 중국의 조선기술은 이러한 해역특성에 적응하여 상이한 선형이 발명, 발전되었다.

  • FAM92A1 (named FAM92A1-271) belongs to the family of proteins with conserved DUF1208 domains. Its function remains elusive. We identified two novel transcript variants (FAM92A1-251, FAM92A1-289) of FAM92A1. The presence of these transcripts in cancerous and normal cells, as well as their influence on cell prolifera-tion and apoptosis, were investigated. The subcellular location of FAM92A1 was determined by fluorescence microscopy. We found that FAM92A1-271 and FAM92A1-289 were highly expressed in both normal and cancerous cells, but FAM92A1-251 was only expressed at a mo-derate level in both types of cell. Overexpression of FAM92A1-271, FAM92A1-251 and FAM92A1-289 inhibited cell proliferation, caused S-phase arrest and induced apoptosis. Subcellular localization showed that FAM92A1 localizes to the nucleus. Our results show that FAM92A1 has different splicing variants, and that it may take part in regulating cell proliferation and apoptosis.

  • In recent years in China, corresponding to a shift in consumption pattern from household basics to greater expenditure on quality of life, new franchising opportunities arise. Although the franchising prospect in China is promising, Korean companies aiming at franchising into China need to be aware of the legal framework for commercial franchise in China as this will have direct impact on their business expansion. Where franchising activities involve trade mark licence, Chinese Franchise Regulations require such trade mark licence agreement to be regulated in accordance with the relevant provisions of the Chinese Trademark Law. Furthermore where one party fails to perform his obligation and it impacts purpose of the contract seriously, the other party could avoid the contract in accordance with the relevant provisions of the Chinese Contract Law. To launch franchising business successfully in China, Korean companies do market research sufficiently before they may commence franchise business. Korean franchisor must register with local authorities in China by own name, and make Chinese partner take charge of management of the distribution network and invitation of franchisee partners.

  • The amount of international trade conducted through Hong Kong (HK) is increasing, thus rendering the legal framework governing contracts of sale between Mainland China (China) and HK is of particular importance. The status of HK under the CISG is currently unclear, however. First, the CISG entered into force in China in 1988. This important development had no legal effect for HK though as China lacked the power to enter into international conventions for HK. Second, the "Letter of Notification" deposited to the Secretary-General of the UN referred a list of treaties to be applied to HK, taking effect from July 1, 1997. This list, however, made no mention of the CISG. Third, China made a reservation in Article 95 of the CISG. Pursuant to Article 1(1)(b) of the CISG, the CISG cannot apply to HK. As a result, the Chinese Arbitral Tribunal apply the Chinese law according to the closest connection principle with the contract. In this case, attention must be given to the different result to which the CISG is applied. Liability for damages pursuant to the Chinese Contract Law (CCL) is just the same as Article 74 CISG, but CCL does not govern the case with substitute transaction and without substitute transaction when the contract is avoided. Therefore, the contract should be governed by the CISG from a business perspective when a contract is concluded between China and HK; otherwise, a promisee could not be fully compensated for all loss incurred.

  • The design concept of a Small High-flux Multipurpose LBE(Lead Bismuth Eutectic) cooled Fast Reactor (SHMLFR) was proposed in the paper. The primary cooling system of the reactor is forced circulation, and the fuel element form is arc-plate loaded high enrichment MOX fuel. The core is cylindrical with a flux trap set in the center of the core, which can be used as an irradiation channel. According to the requirements of the core physical design, a series of physical design criteria and constraints were given, and the steady and transient parameters of the reactor were calculated and analyzed. Regarding the thermal and hydraulic phenomena of the reactor, a simplified model was used to conduct a preliminary analysis of the fuel plates at special positions, and the temperature field distribution of the fuel plate with the highest power density under different coolant flow rates was simulated. The results show that the various parameters of SHMLFR meet the requirements and design criteria of the physical design of the core and the thermal design of the reactor. This implies that the conceptual design of SHMLFR is feasible.
