Fu,Qin Qin,Bae,Jung Han 한국무역상무학회 2008 貿易商務硏究 Vol.40 No.-

This paper analyses the results of a survey questionnaire which is made for logistics service providers in Shanghai, China, Based on 177 valid providers' responses, the study results show that the logistics industry of China consists mainly of small and medium-sized companies. Furthermore, most of the logistics companies are highly capable of providing traditional logistics services and lack of the capability to provide other value-added logistics services. Their self-assessments indicate that they generally perform well in different types of performance measures. This study indicates that the market for 3PL services in China has a reasonable potential for further development, though 3PL practices are still at a nascent stage in China. This paper presents full details and implications of the results of the survey and then tries to provide some helpful suggestion for the development of chinese logistics companies.

Decentralized Iterative Learning Control for Large-Scale Interconnected Linear Systems with Fixed Initial Shifts

Qin Fu,Pan-Pan Gu,Jian-Rong Wu 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.5

This paper deals with the problem of iterative learning control for large-scale interconnected linear systemsin the presence of fixed initial shifts. According to the characteristics of the systems, iterative learning controllaws are proposed for such large-scale interconnected linear systems based on the PD-type learning schemes. Theproposed controller of each subsystem only relies on local output variables without any information exchanges withother subsystems. Using the contraction mapping method, we show that the schemes can guarantee the output ofthe system converges uniformly to the corresponding output limiting trajectory over the whole time interval alongthe iteration axis. Simulation examples illustrate the effectiveness of the proposed method.

Qin Fu,Wei-Guo Gu,Pan-Pan Gu,Jian-Rong Wu 제어·로봇·시스템학회 2016 International Journal of Control, Automation, and Vol.14 No.6

This paper deals with the problem of iterative learning control algorithm for a class of mixed distributedparameter systems. Here, the considered distributed parameter systems are composed of mixed hyperbolicparabolicpartial differential equations. The domain of the system is divided into two parts in which the system ishyperbolic and parabolic, respectively, with transmission conditions at the interface. According to the characteristicsof the systems, iterative learning control laws are proposed for such mixed hyperbolic-parabolic distributedparameter systems based on P-type learning scheme. Using the contraction mapping method, it is shown that thescheme can guarantee the output tracking errors on L2 space converge along the iteration axis. A simulation exampleillustrates the effectiveness of the proposed method.

본 논문은 중국 상해를 중심으로 로지스틱 서비스를 이용하는 기업들의 로지스틱 아웃소싱 실태에 대한 설문조사를 통하여 중국의 물류아웃소싱 관행에 대한 조사연구이다. 중국 상해에 소재하는 158개 제조기업을 대상으로 설문조사를 했다. 연구 결과는 첫째, 전형적 물류를 아웃소싱 하는 제조기업들은 서비스 제공업자들과 장기적 관계를 유지하고 또한 다수의 물류서비스업자들로부터의 물류서비스 구매를 선호했다. 둘째, 대부분의 서비스 이용기업들은 물류서비스 제공기업들에 대하여 만족했고, 물류기업들에게 자사의 물류를 아웃소싱 할 때, 자사의 고객만족도, 물류 수준과 수익개선에 긍정적 영향을 미치는 것으로 나타났다. 셋째, 물류서비스를 이용하는 제조기업들은 물류기업을 선택할 때 가격수준, 핵심적 경쟁력과 평판을 가장 중요한 요인으로 하는 것으로 나타났다. 넷째, 중국에서 3PL 등의 물류전문서비스 사업이 초기단계이지만, 앞으로 발전 잠재력이 매우 큰 것으로 조사되었다. 따라서 본 논문은 상해를 중심으로 중국에서 영업을 하고 중국 국내물류기업 또는 우리나라 투자기업을 포함한 외자물류기업들에게 물류서비스 이용기업들의 물류 아웃소싱 실태와 관행에 대한 정보를 제공함으로 물류서비스산업의 발전에 도움이 될 것으로 사료된다. This paper analyses the results of the survey questionnaires which are made for logistics services users in Shanghai, China. Based on 158 valid users' responses, the study results show that the typical outsourcing logistics users prefer to set up long term relationship with providers and buy services from multiple providers. Most users are satisfied with their providers and believe that outsourcing logistics services has led to positive impact on their customer satisfaction, logistics service levels and revenue improvement. Price levers, core competences, reputation are critical in the selection of an outsourcing logistics provider for users in this study. This study indicates that the market for 3PL services in China has a reasonable potential for further development, though 3PL practices are still at a nascent stage in China. This paper presents full details and implications of the results of the survey and then provides some helpful suggestion for the development of Chinese logistics industry and Chinese logistics companies.

Behavior of improved through-diaphragm connection to square tubular column under tensile loading

Qin, Ying,Zhang, Jing-Chen,Shi, Peng,Chen, Yi-Fu,Xu, Yao-Han,Shi, Zuo-Zheng 국제구조공학회 2018 Structural Engineering and Mechanics, An Int'l Jou Vol.68 No.4

Square tubular columns are commonly used in moment resisting frames, while through-diaphragm connection is the most typical configuration detail to connect the H-shaped beam to the column. However, brittle fracture normally occurs at the complete joint penetration weld between the beam flange and the through-diaphragm due to the stress concentration caused by the geometrical discontinuity. Accordingly, three improved types of through-diaphragm are presented in this paper to provide smooth force flow path comparing to that of conventional connections. Tensile tests were conducted on four specimens and the results were analyzed in terms of failure modes, load-displacement response, yield and ultimate capacity, and initial stiffness. Furthermore, strain distributions on the through-diaphragm, the beam flange plate, and the column face were comprehensively evaluated and discussed. It was found that all the proposed three types of improved through-diaphragm connections were able to reduce the stress concentration in the welds between the beam flange and the through-diaphragm. Furthermore, the stress distribution in connection with longer tapered through-diaphragm was more uniform.

Subcellular Characterization of Porcine Oocytes with Different Glucose-6-phosphate Dehydrogenase Activities

Fu, Bo,Ren, Liang,Liu, Di,Ma, Jian-Zhang,An, Tie-Zhu,Yang, Xiu-Qin,Ma, Hong,Zhang, Dong-Jie,Guo, Zhen-Hua,Guo, Yun-Yun,Zhu, Meng,Bai, Jing Asian Australasian Association of Animal Productio 2015 Animal Bioscience Vol.28 No.12

The in vitro maturation (IVM) efficiency of porcine embryos is still low because of poor oocyte quality. Although brilliant cresyl blue positive (BCB+) oocytes with low glucose-6-phosphate dehydrogenase (G6PDH) activity have shown superior quality than BCB negative (-) oocytes with high G6PDH activity, the use of a BCB staining test before IVM is still controversial. This study aimed to shed more light on the subcellular characteristics of porcine oocytes after selection using BCB staining. We assessed germinal vesicle chromatin configuration, cortical granule (CG) migration, mitochondrial distribution, the levels of acetylated lysine 9 of histone H3 (AcH3K9) and nuclear apoptosis features to investigate the correlation between G6PDH activity and these developmentally related features. A pattern of chromatin surrounding the nucleoli was seen in 53.0% of BCB+ oocytes and 77.6% of BCB+ oocytes showed peripherally distributed CGs. After IVM, 48.7% of BCB+ oocytes had a diffused mitochondrial distribution pattern. However, there were no significant differences in the levels of AcH3K9 in the nuclei of blastocysts derived from BCB+ and BCB- oocytes; at the same time, we observed a similar incidence of apoptosis in the BCB+ and control groups. Although this study indicated that G6PDH activity in porcine oocytes was correlated with several subcellular characteristics such as germinal vesicle chromatin configuration, CG migration and mitochondrial distribution, other features such as AcH3K9 level and nuclear apoptotic features were not associated with G6PDH activity and did not validate the BCB staining test. In using this test for selecting porcine oocytes, subcellular characteristics such as the AcH3K9 level and apoptotic nuclear features should also be considered. Adding histone deacetylase inhibitors or apoptosis inhibitors into the culture medium used might improve the efficiency of IVM of BCB+ oocytes.

Detection of melamine in milk powders based on NIR hyperspectral imaging and spectral similarity analyses

Fu, X.,Kim, M.S.,Chao, K.,Qin, J.,Lim, J.,Lee, H.,Garrido-Varo, A.,Perez-Marin, D.,Ying, Y. Applied Science Publishers 2014 Journal of food engineering Vol.124 No.-

Melamine (2,4,6-triamino-1,3,5-triazine) contamination of food has become an urgent and broadly recognized topic as a result of several food safety scares in the past five years. Hyperspectral imaging techniques that combine the advantages of spectroscopy and imaging have been widely applied for a variety of food quality and safety evaluations. In this study, near-infrared (NIR) hyperspectral imaging technique was investigated to detect low levels (≤1.0%) of melamine particles in milk powders. Following image preprocessing (normalization and background removal), the spectrum of each pixel in the sample images was compared to the pure melamine spectrum by spectral similarity measures including spectral angle measure (SAM), spectral correlation measure (SCM), and Euclidian distance measure (EDM). The three similarity analysis methods provided comparable results for melamine particle detection where imaging allowed visualization of the distribution of melamine particles within images of milk powder mixture samples that were prepared with various melamine concentrations. The classification results were verified by spectral feature comparison between separated mean spectra of melamine pixels and milk powder pixels. The study demonstrated that a combination of NIR hyperspectral imaging technique and spectral similarity analyses was an effective method for melamine adulteration discrimination in milk powders. The method described in this study can also be applied to other chemicals or multi-chemicals adulterant detection in milk powders.
