INPUT ARTICLE: Article: A tool should have come with your oxygen tank that can fit over the top valve on the gas tank itself. Position the wrench over the valve and turn it counter clockwise to open up the airflow from the tank to the regulator. When you unscrew the valve on the top of the tank, you should see the needle move, signifying that there's air coming through your tank. You should also hear and feel oxygen coming through the tube that you connected to the regulator. Your doctor should have informed you of the number that you should keep your regulator at. Follow their instructions and adjust the level of oxygen by turning the dial on the side of the regulator up or down. On the dial, you should see numbers. Move the dial until the number lines up with what your doctor told you. Never change the level of oxygen unless instructed by your doctor. The cannula is the small tubing that fits inside of both your nostrils. Put the parts where the air is coming out into your nose and stick the rest of the tubing up and over your ears. This will keep it in place as you walk around. Sometimes your oxygen tank will come with a full oxygen mask. If you have a facemask, place the mask over your mouth and nose and put the straps on the mask behind your ears. Using the same cannula for over a month will make you more prone to infections. For the same reason, you should also change your cannula after you've been sick. Your tubing will also need to be replaced every 3-6 months. Turn the valve clockwise on the top of your tank to turn off the airflow. This will prevent you from wasting oxygen whenever the tank isn't in use. Consult with your doctor to determine how often you should be using it and when you should turn it off.

SUMMARY: Unscrew the top valve one full turn. Watch the needle on the gauge go up. Adjust the level of oxygen coming through the tank. Insert the prongs on your cannula into your nostrils. Replace your nasal cannula every 2-4 weeks. Turn the tank off when you're not using it.

In one sentence, describe what the following article is about: Open the Run dialog by pressing Windows key + R and enter "dxdiag". This will open the DirectX Diagnostic Tool. It will display an overview of your system. You can click each tab to see information on your display, sound, and inputs. A text box at the bottom of each tab will tell you if there are issues detected with that particular system. If you're having difficulties running programs and are receiving DirectX errors, you may have corrupt or missing DirectX files. The best way to try to fix this is by reinstalling the latest version of DirectX. The installer is available for free from Microsoft. If you are having issues, upgrading to the latest version may help much more than uninstalling. The installer will scan your system and then install the necessary files to update your copy of DirectX to the latest version. Restart your computer after it's finished and check to see if you receive the same errors. Many times, updating your video card drivers will help fix DirectX errors for games and other video-centric programs. To update your driver, you'll need to determine which video card you have, and then download the appropriate file from the manufacturer. To find your video card information, open the Run dialog (Windows key + R) and enter "dxdiag". Click the Display tab, and note the Chip Type and Manufacturer from the Device section. Visit that manufacturer's website. This will typically be NVidia or AMD. Search for your Chip Type on the website and download the latest driver files. Run the driver installer. Your old video card files will be overwritten with the latest version. You may notice your screen flickering during the installation process. If nothing you do seems to be fixing your problem, it may be time to reinstall Windows. This will replace all of your DirectX files with the built-in files with your Windows installation. Reinstalling Windows will take an hour or so, not counting the time it takes to backup and restore your files and reinstall your programs. Follow one of the following guides for your version of Windows: Install Windows 7. Install Windows 8. Install Windows XP. Install Windows Vista.
Summary: Run the DirectX Diagnostic Tool. Download the DirectX installer from Microsoft (but not the file shown in the video above, that is a powerpoint presentation). Run the installer. Update your video card's driver. Reinstall Windows.

INPUT ARTICLE: Article: You can enrich the relationship you have with your child by connecting with them in an age-appropriate way. Teach, work on projects, and play on a level that your child is familiar with. This helps them bond with you and makes you seem more approachable. If you have a toddler, get on the floor and build a city out of blocks. If you have older adolescents or teens, join in on a round of video games. You are more likely to spark conversation during these types of activities than by trying to get them talking at the dinner table. While your children need to know that you acknowledge and respect their individuality, it also counts when you uplift the family as a unit. Make family time a regular and special part of your routine. Eat meals together most nights of the week, and have everyone share their peaks and pits (i.e. best and worst moments) of the day. Go to sporting events, movies, or community gatherings together. Spending time together as a unit is essential. You should also set aside time to focus on each individual child. Prioritizing one-on-one time helps you form a connection with each child. Plus, it also helps you focus on each child's individual strengths and talents. Find a shared hobby to engage in with each of your children. Maybe you will teach one kid how to fish on weekends. Or, work with another on perfecting a piano performance. Free up part of your weekly schedule to build a special relationship with each child. Parents who have good relationships with their children are involved in their lives. You can't expect to have a strong bond with your children if you simply say "good morning" and "good night" each day. It's understandable that you're busy juggling work and other responsibilities, but you should also make an effort to get to know your kids and learn about what's happening in their lives. If you have some free time, offer to volunteer at school, coach a softball game, or meet with your children's teachers regularly to stay updated on their academic performance. Sit down with them as they do homework. Help them practice their lines for the school play. Invite your kids' friends over so you know what kind of influences they are around. Let your kids know that things don't always have to be so serious between you. Of course, you want them to respect your authority, but you also want to laugh with them. A sense of fun can liven up their lives and build fond memories. Make crazy faces or noises to supplement mealtimes or playtime with smaller children. Act silly with adolescents by pulling pranks or telling jokes.

SUMMARY:
Get on their level. Emphasize the importance of family time. Dedicate one-on-one time for each child. Stay in touch with academics, friendships, and extracurriculars. Kid around.
