But good parent-child relationships may often require diet, sleep, and daily activities to maintain.†Matthew Andersson researcher said.
In 1995, he visited more than 2,700 adults between the ages of 25 and 75 about how their parents treated them during their childhood. About a decade later, nearly 1,700 participants completed follow-up surveys and Andersson investigated their health.
The study found that good parent-child relationships may also be affected by lower socioeconomic status. Previous studies have shown that low parental education tends to use force or threaten children, which may weaken the relationship between them.
Abusive or lack of warm family relationships during childhood can also cause high inflammatory diseases in adulthood.
Andersson said children growing up in stressful or domesticated environments may also lack regular mealtimes and increase their chances of eating sugary or high-fat snacks instead of healthy foods.
According to the study, they are also less likely to have regular sleep and daily activities, and regular daily activities are an important habit to help them develop healthy aging.
The article was published in the Journal of Health and Social Behavior on September 20.
"Many studies suggest that socioeconomic status and parent-child relationships are highly correlated and even interchangeable. But in fact, the relationship between them may be completely independent for the health of children," Andersson said.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
