The Influence of the Number of Employees on the Quality Management in Pharmaceutical Production  [PDF]
Jingjing Luo, Gordon G. Liu, Weijun Tian
Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.73005
Abstract: Based on the survey data from the questionnaire of Quality Management of Pharmaceutical Production Enterprises in Anhui Province, this research examines the relationship between the number of employees and inspection for GMP of pharmaceutical manufacturers by adopting OLS model and Logit model. We find that the more employees there are, the better their inspection results are. Enterprises with large number of employees generally have plenty people to deal with the problems of quality supervision in the production of pharmaceuticals and have a good knowledge of GMP. They can produce high quality medicines. Therefore, small companies should be supervised frequently. In daily supervision, through the number of employees, it can quickly judge the pros and cons of the quality management level of the company, which is beneficial to allocate regulatory resources rationally.
Distributed Collaborative Camera Actuation Scheme Based on Sensing-Region Management for Wireless Multimedia Sensor Networks
Wusheng Luo,Qin Lu,Jingjing Xiao
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/486163
Abstract: Considering the high energy consumption of image acquisition, computation, and transmission in wireless multimedia sensor networks (WMSNs), two-tier network structure is usually used to lighten the energy consumption burden on camera sensors. Thus, a camera sensor can only be actuated when an event is detected by scalar sensors within its field of view (FoV). In this paper, we study the event-driven camera actuation problem and propose a distributed collaborative camera actuation scheme based on sensing-region management (DCCA-SM). The basic idea of this scheme is to divide the whole sensing field into many sensing regions which are covered by different sets of camera sensors. During the running of the network, by forming a cluster of the scalar sensors in each sensing region, the events occurring in each sensing region can be managed by the scalar cluster head. Therefore, by hearing from the scalar cluster heads, each camera sensor can know the exact coverage overlaps without changing information with the neighboring camera sensors. Meanwhile, sensing-region management avoids repeatedly event reporting from scalar sensors. In order to show the performance of the DCCA-SM, a simulation has been conducted. The comparative performance evaluations demonstrate effectiveness and energy efficiency of the proposed scheme.
Feeding Deterrence of Common Spices against Helicoverpa armigera Larvae  [PDF]
Weizheng Li, Jingjing Hu, Jing Yang, Guohui Yuan, Xianru Guo, Meihao Luo
Advances in Bioscience and Biotechnology (ABB) , 2014, DOI: 10.4236/abb.2014.513117
Abstract: Edible spices with strong smells or heavy tastes may be a promising resource of feeding deterrents. We compared the feeding deterrence of the ethanol extracts of 21 common spices against the larvae of a generalist pest species, Helicoverpa armigera, using a multiple-choice leaf disc bioassay. The results show that Zanthoxylum bungeanum extract (as a reference) always evoked significant feeding deterrence, while Piper nigrum (both black pepper and white pepper), Piper longum, and Angelica dahurica evoked the strongest and equivalent feeding deterrence. The potent feeding deterrent activity of Piper species may be a common characteristic at genus level.
Minimizing the scattering of a non-magnetic cloak
Jingjing Zhang,Yu Luo,Niels Asger Mortensen
Physics , 2010, DOI: 10.1063/1.3366726
Abstract: Nonmagnetic cloak offers a feasible way to achieve invisibility at optical frequencies using materials with only electric responses. In this letter, we suggest an approximation of the ideal nonmagnetic cloak and quantitatively study its electromagnetic characteristics using a full-wave scattering theory. It is demonstrated that the forward scattering of the impedance matched cloak increases dramatically as the thickness of the cloak decreases. Nevertheless, it is still possible to effectively reduce the total scattering cross section with a very thin cloak whose impedance is not matched to the surrounding material at the outer boundary. Our analysis also provides the flexibility of reducing the scattering in an arbitrary direction.
Cloaking of levitating objects above a ground plane
Jingjing Zhang,Yu Luo,Niels Asger Mortensen
Physics , 2010, DOI: 10.1063/1.3493186
Abstract: An approach to hiding objects levitating or flying above a conducting sheet is suggested in this letter. The proposed device makes use of isotropic negative-refractive-index materials without extreme material parameters, and creates an illusion of a remote conducting sheet. Numerical simulations are performed to investigate the performance of this cloak in two-dimensional (2D) and three-dimensional (3D) cases.
The Influence of the Change Frequency of Director of Manufacturing Management on the Quality Management
Take Anhui Province as an Example

Jingjing Luo, Gordon G. Liu, Weijun Tian
Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.79006
Abstract: Based on the survey data from questionnaire of Quality Management of Pharmaceutical Production Enterprises in Anhui Province, this research examines the relationship between the change frequency of production director and GMP inspection results of pharmaceutical manufacturers by adopting OLS model and Logit model. We find that director of manufacturing management plays a direct role in enterprise production management as senior administrator. If director of manufacturing management changes more times, the enterprise’s drug production management will lose persistent stability. As a result, the quality of drug production is affected. Without ability to produce high-quality drugs, the GMP inspection results of pharmaceutical enterprises are poor. Thus, this paper suggests that in daily drug quality supervision, enterprises that frequently change director of manufacturing management should be paid more attention to, and we should increase the frequency of examination, so as to reasonably allocate regulatory resources and carry out targeted supervision.
