About Cabling Installation & Maintenance:

Bringing practical business and technical intelligence to today's structured cabling professionals.

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on:

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Optimal Sleep Duration Linked to Decreased Risk of Heart Disease

By: MerxWire

What is your average daily sleep time? Some individuals sleep for only 3 to 4 hours per night, while others manage to sleep for 6 to 7 hours. Scientific research indicates that the latter group exhibits better cardiovascular health data.

Detroit, MI (Merxwire) – The vital importance of sleep should not be overlooked. According to a study by Henry Ford Hospital in the United States, sleeping too long or too short may increase the risk of heart disease. Researchers have found that sleep can play a role in cardiovascular risk in the same way as diet, smoking, or exercise. It is recommended that a suitable sleep time is 6 to 7 hours.

Researcher Kartik Gupta and his team analyzed the data of participants in the National Health and Nutrition Examination Survey from 2005 to 2010, a total of 14,079 people. The average age of these participants was 46, and 10% of them had a history of heart disease and related complications.

“Sleep is often overlooked, but it may play a role in cardiovascular disease, which may be one of the most cost-effective ways to reduce the risk of cardiovascular disease.” Dr. Kartik Gupta said.

Participants were divided into three groups for observation. They were followed for an average of 7.5 years to observe their deaths from heart disease, heart failure, or stroke. The researchers compared the participants’ Atherosclerotic cardiovascular disease (ASCVD) and C-reactive protein (CRP) from the participants’ sleep and related data.

“Participants with insufficient sleep or too long sleep have higher CRP indicators, which increased inflammation measured by CRP may cause. Those who show insufficient sleep or too much sleep have a higher risk of inflammation.” Dr. Kartik Gupta explained.

Researchers also found that people who sleep 6 to 7 hours a night have the lowest chance of dying from a heart attack or stroke. However, people who sleep 6 to 7 hours a night have the same ASCVD as those who sleep more than 7 hours, indicating that ASCVD may not fully reflect the risk of heart disease.

Since everyone needs to pay different labors at work, and the sleeping environment and quality are also different, will these lead to differences in research results? The research team emphasized that the current study suggests that sleep for 6 to 7 hours can reduce the risk of heart disease, but sleep includes conditions such as depth and quality, so the results need to be further verified.
