Opis:
Objectives To compare the number and quality of public, environmental and occupational health articles published in international journals from the 3 major non-English speaking countries of East Asia: China, Japan and Korea. Material and Methods Public, environmental and occupational health articles from China, Japan and Korea that were published in 161 journals from 2003 to 2012 were retrieved from the Science Citation Index Expanded (SCIE) database. We recorded the numbers of total articles, impact factors (IF), citations, number of articles in top 10 journals, references as well as the article distribution from various regions in China. Results From 2003 to 2012, China, Japan and Korea published 5713, 3802 and 1967 papers respectively, with accumulated impact factor of 14 934.55, 8758.36 and 6189.25, the average impact factor of 2.61, 2.30 and 3.15 and the average citation numbers per document of 5.08, 6.49 and 5.25. In the top 10 high-impact public, environmental and occupational health journals, China, Japan and Korea accounted for 50.19%, 20.34% and 29.47% of all the papers published in those journals, respectively. Total impact factors of the most popular 10 papers for China, Japan and Korea were: 26.23, 27.08 and 26.91. Distribution of scientific papers among regions was unbalanced in China, for Hong Kong and Taiwan it accounted for 47.31% of the papers from China. Conclusions From 2003 to 2012, both the quality and number of papers from China published in public, environmental and occupational health journals have greatly improved. China exceeded Japan and Korea in the number, accumulated impact factor, total citation times and the average number of references, while Korea had the highest average impact factor. Japan had the highest journal impact factor among the most popular journals, and the highest average citation number per document.

Opis:
A grey box framework is applied to model ship maneuvering by using a reference model (RM) and a support vector machine (SVM) (RM-SVM). First, the nonlinear characteristics of the target ship are determined using the RM and the similarity rule. Then, the linear SVM adaptively fits the errors between acceleration variables of RM and target ship. Finally, the accelerations of the target ship are predicted using RM and linear SVM. The parameters of the RM are known and conveniently acquired, thus avoiding the modeling process. The SVM has the advantages of fast training, quick simulation, and no overfitting. Testing and validation are conducted using the ship model test data. The test case reveals the practicability of the RF-SVM based modeling method, while the validation cases confirm the generalization ability of the grey box framework.

Opis:
Gasification slag is the solid waste produced in the coal gasification process, and its treatment and disposal problems are becoming more and more serious. In this study, the gasification slag produced in a chemical base in northern China and its residual carbon obtained by gravity separation of water medium were taken as the research objects, and their physicochemical properties were analyzed comprehensively. The residual carbon products, ash-rich products and high-ash products were obtained from the gasification slag after gravity separation. Under the optimal structure, the ignition loss of residual carbon products was reduced from 79.80% to 16.84%, and the yield was 11.64%. The high content of amorphous carbon and developed pores in the residual carbon provide the possibility of manufacturing high value-added materials. Raman spectrum showed that the residual carbon had lower aromaticity, higher content of small and medium aromatic ring structures, lower structural stability and easier combustion. Thermogravimetric combustion kinetics showed that the average combustion rate of residual carbon was 0.325(dm/dt)mean/%•min−1, the comprehensive combustion characteristic index was 1.41•10−9%2•min−2•°C−3. It has excellent performance and can be used as a raw material for mixed combustion in a circulating fluidized bed. The analysis of physical and chemical properties of residual carbon is of great significance for follow-up exploration of the resource utilization and high-value utilization of the residual carbon.
