Freight Forwarder and NVOCC in China: from the Aspects of Practice and Law
( Guo Ping ),( Ying Ying Li ) 고려대학교 법학연구원 2015 The Asian Business Lawyer Vol.16 No.-
NVOCC and freight forwarder are one of the most important intermediaries in shipping industry. Judicial branches and practices in China pay more attention to the regulation of this industry in the past 30 years. There are several regulations and rules on the management of international freight forwarding operation as well Non-vessel operation by some governmental authorities, and also the Supreme People``s Court of China had promulgated one judicial interpretation on the issue of freight forwarder disputes cases in 2012. The approaches for providing security bond may be chosen byNon-vessel operating common carrier in past years. In 2013, China (Shanghai) Pilot Free Trade Zone was approved by the Council of State. Since May 15, 2014, Shanghai Municipal Transport Authority has been in charge of the approval of the application for qualifications of Non-Vessel Operating Service under some specific situations. Although Freight forwarder and NVOCC legal system develop fast and timely in recent years in China, but there is still room for improvement. The Judicial Interpretation 2012 only stipulates the responsibility of freight forwarding and keeps silent on liability insurance of freight forwarder up to now. The operating procedures aim to relive operator of non-vessel operating service from the stress of security deposit and fail to deal with the liability insurance issues in details, too. To differentiate freight forwarder and NVOCC for guiding the practice, it is necessary to analyze the differences and relationships between freight forwarder and NVOCC as well as the legal status and supervision of them on the basis of the above Chinese Regulations and Rules.

Bio-oxidation is an effective technology for treatment of refractory gold concentrates. However, the unsatisfactory oxidation rate and long residence time, which cause a lower cyanide leaching rate and gold recovery, are key factors that restrict the application of traditional bio-oxidation technology. In this study, the oxidation rate of refractory gold concentrates and the adaption of microorganisms were analyzed to evaluate a newly developed two-step pretreatment process, which includes a high temperature chemical oxidation step and a subsequent bio-oxidation step. The oxidation rate and recovery rate of gold were improved significantly after the two-step process. The results showed that the highest oxidation rate of sulfide sulfur could reach to 99.01 % with an extreme thermophile microbial community when the pulp density was 5%. Accordingly, the recovery rate of gold was elevated to 92.51%. Meanwhile, the results revealed that moderate thermophiles performed better than acidophilic mesophiles and extreme thermophiles, whose oxidation rates declined drastically when the pulp density was increased to 10% and 15%. The oxidation rates of sulfide sulfur with moderate thermophiles were 93.94% and 65.73% when the pulp density was increased to 10% and 15%, respectively. All these results indicated that the twostep pretreatment increased the oxidation rate of refractory gold concentrates and is a potential technology to pretreat the refractory sample. Meanwhile, owing to the sensitivity of the microbial community under different pulp density levels, the optimization of microbial community in bio-oxidation is necessary in industry.

This study explored an integrated strategy for extraction and preparative separation of four anthocyaninsfrom Ribes nigrum L. using DES-based microwave assisted extraction andflash chromatography. Theextraction yield of anthocyanins reached 2.03 mg/g after optimization. An efficient preparativeseparation process of four main anthocyanins by macroporous resin andflash chromatography wasestablished afterwards. The yields of D3G, D3R, C3G and C3R reached 0.32 mg/g, 0.47 mg/g, 0.18 mg/g and0.43 mg/g with the purities of more than 95%, respectively. The developed procedure represents anefficient and convenient alternative for the systematic utilization of natural products from plantmaterials.
Characterization of the Open Reading Frame 35 of Bombyx mori Nucleopolyhedrovirus
Ying Min Zhu,Guo Hui Li,Qin Yao,Ke Ping Chen,Zhong Jian Guo 한국잠사학회 2010 International Journal of Industrial Entomology Vol.21 No.2
Open reading frame 35 (bm35) of the Bombyx mori nucleopolyhedrovirus (BmNPV) is a special gene whose homologues are only found in some group-I nucleopolyhedroviruses, suggesting that bm35 plays a specific role in the viral life cycle. This paper described the characterization of BmNPV bm35. Computerassisted sequence analysis shows that a putative RING finger motif is observed in the protein, Bm35 encoded by bm35. The coding sequence of bm35 was amplified and subcloned into the vector pET30a(+) and the (His)6-tagged fusion protein His-Bm35 was expressed in the Escherichia coli BL21 (DE3) LysS cells. The bm35 transcript and Bm35 protein were detected in BmNPV-infected BmN cells at 12~48 h post infection (p.i.) by RT-PCR and Western blot analysis using the polyclonal antibody generated by immunizing a rabbit with purified (His)6-tagged Bm35, suggesting that bm35 is synthesized in the late stage of BmNPV infection cycle. Bm35 was not a structural component associated with budded virus (BV) and occlusion derived virus (ODV). These data indicated that bm35 is a functional gene in the BmNPV life cycle.

Background: Although Becker`s nevus (BN) is a relatively common disease, the systematic studies of clinicopathological and immunohistochemical results are poorly reported. Objective: To investigate the clinicopathological features and immunohistochemical alterations of keratinocyte proliferation, melanocyte density, smooth muscle hyperplasia and nerve fiber distribution in BN. Methods: Clinical and pathological data were collected in 60 newly-diagnosed BN cases. Immunohistochemical stain of Ki-67, Melan-A, keratin 15, smooth muscle actin and protein gene product 9.5 was performed in 21 cases. Results: The median diagnostic and onset age was 17 and 12 years, respectively. Skin lesions usually appeared on the upper trunk and upper limbs. The pathological features included the rete ridge elongation and fusion and basal hyperpigmentation. Epidermal Ki-67, Melan-A and keratin 15 expression and dermal nerve fiber length were significantly higher in lesional and perilesional skin than in normal skin (p<0.05∼0.01), while smooth muscle actin expression was upregulated only in skin lesion (p<0.05). Conclusion: Although the clinical diagnosis of BN is often straightforward, histopathology is helpful to differentiate from other pigmentary disorders. The hyperproliferation of keratinocytes, melanocytes, arrector pili muscle and dermal nerve fibers could be involved in the patho-genesis of BN. (Ann Dermatol 28(6) 697∼703, 2016)

Members of the genus Bacillus are known to play an important role in promoting plant growth and protecting plants against phytopathogenic microorganisms. In this study, 21 isolates of Bacillus spp. were obtained from the root micro-ecosystem of Suaeda glauca. Analysis of the 16S rRNA genes indicated that the isolates belong to the species Bacillus amyloliquefaciens, Bacillus velezensis, Bacillus subtilis, Bacillus pumilus, Bacillus aryabhattai and Brevibacterium frigoritolerans. One of the interesting findings of this study is that the four strains B1, B5, B16 and B21 are dominant in rhizosphere soil. Based on gyrA, gyrB, and rpoB gene analyses, B1, B5, and B21 were identified as B. amyloliquefaciens and B16 was identified as B. velezensis. Estimation of antifungal activity showed that the isolate B1 had a significant inhibitory effect on Fusarium verticillioides, B5 and B16 on Colletotrichum capsici (syd.) Butl, and B21 on Rhizoctonia cerealis van der Hoeven. The four strains grew well in medium with 1-10% NaCl, a pH value of 5-8, and promoted the growth of Arabidopsis thaliana. Our results indicate that these strains may be promising agents for the biocontrol and promotion of plant growth and further study of the relevant bacteria will provide a useful reference for the development of microbial resources.

This paper reports a systematic study on the doping of two potassium atoms in small-sized neutral boron clusters. The CALYPSO software in conjunction with DFT was used to anticipate the low-energy structures, optimize their geometry, and adjust their energies. With increasing size, the structural development of the K2Bn (n=1–12) clusters was revealed, and we discovered that the majority of their ground-state structural isomers structurally inherited well from the corresponding ground-state isomers of pure B clusters. A fresh fnding was made after confrming the NPA (natural population analysis) of the low-lying K2Bn (n=1–12): every doped K atom in the structure has a positive charge. According to relative stability analysis, the most stable K2B8 cluster within the parameters of our investigation has a HOMO–LUMO gap of 3.31 eV. Strong interactions between K-4s and B-2P AO were also discovered through an additional examination of the molecular orbitals and bonds of K2B8 clusters. These interactions may be the primary cause of K2B8's exceptional stability. We hope that our research will be useful in the future for synthesizing and using doped boron-based nanomaterials.
