We used the 2011-2013 data to predict the number of new cases and deaths in 2018 and the 2003-2013 data to analyze trends in cancer incidence and mortality. The goal is to enable cancer prevention and control directions. Our results indicated that stomach cancer is the most common cancer. For all cancers combined, the incidence and mortality rates showed significantly increasing trends(+2.63% per year; P 〈 0.05 and +1.9% per year; P 〈 0.05). This study revealed a significant cancer burden among the population of this area. Cancer screening and prevention should be performed after an epidemiological study of the cause of the cancer is completed.展开更多

Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 1985 to 1999 rapidly developed which showed a difference of mean temperature above +2 0 Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be +4 5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.展开更多

On digging a navigational canal at the lowest cost in a plain area within the territory of Russia, with a length of approximately 600 kilometers (616 km), starting from the nearest bay in the Caspian Sea, passing near the city of “Pyatigorsk” to the city of “Sochi” on the Black Sea, while it comes: -The strategy of the waterway and the sea channel between the “Caspian Sea” and the “Arabian Gulf” through the “lands belonging to Iran” by digging and cutting a path in the rocks with a width of 100 meters and a length of about 700 kilometers, and at a time rate of less than 10 years, and this project will liberate all countries in the Caspian Sea, and the study concludes with the strategy of the navigational channel between the “Arabian Gulf” and the “Mediterranean Sea” through the two countries of “Iraq-Syria”, with a length of about 1350 km, and the world will benefit in the security, commercial and political fields.展开更多
