Symbolic Management of the Degree of Information Security by Integer Splitting

This paper demonstrates the application of module arithmetic for controlling the level of information security by a new technique referred as integer splitting. The basic definitions and concepts of the method are provided. The mathematical function of arising transformation is described in detail; its properties were studied and the basic theorems were proven that justify the use of splitting in practical applications. An active system was designed and characteristic cases of its operation are considered.

夏季消暑与近代社会生活——以1843—1937年上海为例

防暑降温是人们对自然环境做出的本能反应,也是夏季日常生活的重要组成部分。以开埠前人们夏季防暑降温生活为对照,通过对近代上海市民夏季生活中防暑降温行为的分析和考察发现,近代上海社会生活变迁引起了人们夏季防暑降温在服饰、饮食、居家、户外活动、物用及时间安排等方面的变化,并呈现出社会化、大众化、多样性和时代性的特点,进而揭示近代社会从传统走向现代的历史发展过程。
