Research on Distribution Efficiency of Automobile After-sales Spare Parts Based on System Dynamics

Research Article of Scientific Research and Reviews Research on Distribution Efficiency of Automobile After-sales Spare Parts Based on System Dynamics TENG Jiayi1 and Han Xiaolong2 1Institute of Logistics Science and Engineering, Shanghai Maritime University, Shanghai 201306, Submission direction: Logistics Economy and Supply Chain Management; 2Shanghai Institute of Logistics Science and Engineering, Shanghai Maritime University, Shanghai 201306 The distribution of aftermarket spare parts is an important part of automotive aftermarket parts logistics. The level of distribution efficiency is the key factor affecting customer satisfaction and the economic benefits of accessory companies. The paper uses the theory and modeling method of system dynamics to study the efficiency of the automobile after-sales spare parts distribution system, establishes a dynamic simulation model, and experiments and improves the model based on three important time elements in the system. Experiments show that shortening the delay time between nodes and adjusting the inventory adjustment time properly have positive practical significance for improving the distribution efficiency of aftermarket spare parts.

Improving urban air quality in China: investigation and control measures of PM2.5, PM10, NO2 and SO2 in air

Research Article of Scientific Research and Reviews Improving urban air quality in China: investigation and control measures of PM2.5, PM10, NO2 and SO2 in air Hui Wang1, Guozhu Chen2, Rui Yang1, Baolei Lv1, Shiyu Liu1, Junqing Sun1, Shaoliang Yang1, Xinjun Li1* 1.School of Chemical and Biological Engineering, Qilu Institute of Technology,China. 2.College of Hydraulic & Environmental Engineering, China Three Gorges University, China. In recent years, the quality of urban atmospheric environment in China has caused widespread concern in the whole society. Improving air quality has become a major content of air pollution prevention and control in China. To do a good job in atmospheric prevention and control, we must investigate and analyze the sources of major atmospheric pollutants and their pollution characteristics firstly. With the acceleration of urbanization, the air pollution situation in Jinan city has become an environmental problem that people are particularly worried about. Based on the monitoring data of Jinan atmospheric environment, this paper analyzed the monthly average concentration values of PM2.5, PM10, NO2 and SO2 in Jinan City from 2015 to 2017. Meanwhile, the main reasons for the air pollution in Jinan City were clarified in detail. Finally, air pollution control strategies were proposed corresponding the aspects of pollution sources, topography and meteorological conditions, rational planning, environmental supervision capabilities, environmental awareness, and practical treatment technologies in Jinan City. These measures can provide a theoretical basis for relevant leading departments to build a beautiful city. Keywords: Air quality; Environmental protection; Prevention suggestions ...

Review on Hide and Skin Value Chain in Ethiopia

Review Article of Scientific Research and Reviews Review on Hide and Skin Value Chain in Ethiopia Tilahun Kenea Department of Agribusiness and Value Chain Management, Mettu University, P.O.Box 318, Mettu, Ethiopia Ethiopia’s economy is predominantly agricultural where the livestock sub-sector plays substantial role. Hides and skin is an important strategic sector for the economic and industrial development of Ethiopia. Though the country has very good potential for supplying finished skins and hides products to the world market, the quality of skins and hides supplied has rather deteriorated over time. Therefore, this seminar was conducted to review hide and skin value chain in Ethiopia, to review hide and skin value chain actors, maps and its value addition in Ethiopia, to review the major constraints and opportunities of hide and skin in Ethiopia ,to review hides and skins production ,utilization and its constraint in Ethiopia and to review hide and skin marketing and its constraints in Ethiopia . Poor quality of hides and skins , Poor animal husbandry ,Improper preserved hides and skins ,Lack of price incentives ,absence of quality grading, reflections of the economic policy, market information, and requirements from the tanneries and end market are main challenge observed hide and skin value chain . Creation of awareness among extension staff, butchers, collectors, tanners and other stakeholders and the general public of the economic importance of hides and skins are very important. Developing Clear pricing system based on grading and standard of hide and skin and improving access to market information As well as Clear policy and strategy for the development of hide and skin sector should be developed by Member State that have not done so far.

Globally in 2015, there were an estimated 480, 000 new cases of multidrug-resistant TB. According to the anti-tuberculosis drug resistance survey conducted nationwide in Ethiopia in 2012 among 804 newly diagnosed TB cases 1.6 % were found to be infected with MDR-TB. The continuous challenge in the occurrence and management of Multidrug-Resistant Tuberculosis (MDR-TB) in the country in general and Nekemte Referral hospital in particular prompted this study which seeks-to investigate the risk factors for MDR-TB.Unmatched case control study design was conducted to identify the risk factors for multi-drug resistant tuberculosis among tuberculosis patients of Nekemte Referral Hospital. All MDR-TB (21 cases) and Non-MDR-TB (44 controls) patients’ registered from September 2016to August 2017 in this Hospital were included in the study. Face-to-face interview and Patient medical records review were used to collect the data. In bivariate analysis; variables which had P-value <=0.25 wereentered into multi-variate logistic regression model. P-value <0.05 taken as statistically significant. A total of 65 tuberculosis patients (21 cases and 44 controls) included in this study; response rate 100 %. Previous tuberculosis treatment (AOR = 0.975, 95 % CI ...
