내쇼날 지오그라프지 놀라운 사진들: National Geographic's Amazing Photos

At the end of each year, National Geographic rounds up its best photos - and here we will take a look at 20 of them. Every day throughout the year, National Geographic releases a Photo of the Day - some classic, others quirky, but they always select an image with a story to tell. In their pick for 20 of the best photos they selected photographs with the most shares, likes, and comments from the social sphere. Let's take a look. Which photo do you 


1. Cracking the Surface, Lake Baikal
national-geographic
Photographer Alexey Trofimov captured quite an unusual picture of the ice here. He writes that the "ice on Lake Baikal is a very interesting phenomenon."


2. The Village, Hungary
national-geographic
This photograph was taken by Gabor Dvornik, who lives half a mile from The Village, which is set on a natural reserve in Sződliget Hungary. While the air in this place is special every season, it is especially rare to have a nice, misty day. "It was utterly ghostly and very moody out there" he writes.


3. When Penguins Attack, Antarctica
national-geographic
Captured with a GoPro on Antarctica's sea ice. The photographer, Clinton Berry had studied the movements of the penguins for weeks. The day that this shot was taken, there were over 60 penguins and Berry says that there was a bit of luck involved too.


4. Against the Wind, Canada
national-geographic
In this shot, photographed by Dominic Roy, a snowy owl appears to be fighting against the elements during extreme weather conditions near Quebec City, Canada.


5. Something's Fishy, British Columbia Coast, Canada
national-geographic
Photographed by Ian McAllister using an underwater housing, this shot captures an intimate portrait of a wolf wading through the inter-tidal zone on the British Columbia coast in Canada. The wolf took a break from eating herring roe to investigate the photographer's half-submerged camera.


6. Who's There?
national-geographic
While taking this photo, Cezary Wyszynski imagined this mouse thinking 'Who was knocking at my door?'


7. Falls in Autumn, Plitivice Lakes National Park, Croatia
national-geographic
This is Croatia's oldest and largest National Park, which boasts 16 terraced lakes, formed by natural travertine dams that change color throughout the day. This photo was taken by Vedrana Tafra.


8. Bioluminous Larak, Iran
national-geographic
This shot was taken along the shore of Larak, Iran - an island in the Persian Gulf. "The magical lights of the Plankton enchanted me so that I snapped the shot," Pooyan Shadpoor says.


9. Mother of the Forest, Madagascar
national-geographic
The boabab trees on Madagascar are 800 years old. They are home to snakes, bats, bush babies, bees, and, at times, humans. The trees are an important source of water - one can store up to 4,000 liters of water in its trunk. This photo was taken by Marsel Van Oosten.


10. Fox Found, Gran Paradiso National Park, Italy
national-geographic
Gran Paradiso National Park was once a royal hunting retreat. Here, a red fox lies in wait, camouflaged by the autumn woods. This photo was captured by Stefano Unterthiner.



11. Dancing with the Moon, Iceland
national-geographic
The vivid beams of light are a result of collisions between charged particles released from the sun's atmosphere and gaseous particles in Earth's atmosphere. This shot was captured by Andrew George.


12. Winter White, Gran Paradiso National Park, Italy
national-geographic
Another great shot taken at Italy's Gran Paradiso National Park by Stefano Unterthiner. Among the wildlife inhabiting this park are ibex, chamois, red foxes, and ermines (pictured here).


13. Big Baby, Tonga
national-geographic
This young humpback whale was captured in the waters off Tonga. Karim Iliya writes that she "could not help but wave and smile at the newborn whale almost three times my length. Curiosity got the better of it and emerging from under its mother's fin, it swam toward me, approaching less than 30 centimeters" (11 inches).


14. Bird Feeders, China
national-geographic
Abderazak Tissoukai was near Xingping in China's Guanxi region when he took this shot of a cormorant (a trained bird, used to help men fish in rivers) and a fisherman at sunset. "Xingping is definitely one of the most beautiful places in China, with its scenic karst landscapes, and its traditional and genuine people," he writes.


15. Kit Friendly, Estonia
national-geographic
This kit fox appears to be weighing the presence of Kalmer Lehepuu's camera lens. He writes that "on one beautiful evening, the mother went to get food and left the kits on their own." Lehepuu then snuck closer to observe them.


16. Shining Through, Apostle Islands, National Lakeshore, Wisconsin
national-geographic
This shot, taken by Ernie Vater, captures the setting sun shining the rough ice on the shore of a frozen Lake Superior. Part of the beauty of this place is its silence. Vater writes, "you hear nothing except for the occasional creaking of the ice".


17. Yellow Jellies, Rock Islands of Palau
national-geographic
These golden jellyfish are harmless to humans, they spend much of their time following the sun as it moves across the sky. Sunlight for these jellyfish is essential. Captured by Ciemon Frank Caballes.


18. All the Fish in the Sea, Cabo Pulmo

"This is what our oceans should look like", Jeff Hester, who captured this shot, says. But Cabo Pulmo, a marine park off Mexico's Baja California, hadn't always been this way.


19. Imperial Blossoms, Japan
national-geographic
These weeping cherry tree blossoms, were captured on the grounds of the Imperial Palace in Kyoto, Japan. They typically bloom in late March and early April. This photo was taken by Yukio Miki.

7가지 Computer Window의 유용한 기능: 7 Helpful Windows Tools

Windows has many built-in tools and functions that make everyday tasks a lot easier. However, the majority of these tools are difficult to find and use effectively. Therefore, to help you get the most out of Windows, here's a list of 7 lesser-known Windows tools. These tools are very effective and can help you out a lot if you learn how to use them.

1. System Configuration
System configuration gives you powerful configuration options in a single window.
To access System configuration options, press the Windows R keys and type "msconfig" in the "Run" dialog. You will then see multiple tabs to configure the system, like:
Boot
Here you change boot options, such as boot into Safe Mode, change the default operating system, and other similar boot options.
You can also go to "Advanced Options" to limit RAM usage as well as to control how much processor cores Windows should use.
Services
In services, you can find a list of background services that start to work as soon as Windows starts up.
The majority of them are Microsoft services that you should not mess around with, but there is the option of selecting "Hide all Microsoft services" so that you can only see all third-party background services.
You should disabled the background services that you don't want to use as they are using resources and can slow your computer down.
Startup
In Windows 8 and 10, this option has been relocated to Windows Task Manager.
Here you can see all the programs that start when Windows boots. To speed up your computer, you should disable programs that start up with windows.


2. Event Viewer
Windows keeps a record of all the events, which can be accessed in theWindows Event Viewer. It shows Windows services accessed, warnings and errors, and logins and other similar data that can be used for detecting activity or problems.
I usually use it to detect unauthorized access to my PC.
To access the Event Viewer, go to Control Panel > System and Security > Administrative Tools > Event Viewer. Alternatively, you can press Windows +R key and type "eventvwr" in the "Run" dialog.
Event Viewer can be used for many purposes, but detecting a problem is one of its main functions. In the main interface, Event Viewer will show all warnings and errors.
However, you don't need to pay attention to them unless you actually have a problem. Windows is very sensitive when it comes down to creating error logs, so even a slight change in behavior will lead to an error or warning entry in the Event Viewer.
If you've recently had a problem - like your PC crashed - then you can go to the Event Viewer and check the errors that occurred during that specific time.Double clicking on an event will provide you with more details and solutions.


3. Data Usage Tracker 
If you have Windows 8.1 or 10, then you can take advantage of the built-in data usage tracker to see how much internet data you have used. If you have limited internet usage, then this could save you from extra data usage charges.
To check, go to Settings and click on "Network & Internet." Here you will see the total data that you have used in the last 30 days in the "Data Usage" section.
 
4. Startup Repair
Windows 8 and 10 both come with a native "Startup Repair" tool that will help you fix common startup issues that may be slowing your computer's boot process or even preventing Windows from starting.
If you can access Windows, then press and hold the "Shift" key and click the"Restart" button to restart Windows boot options. If Windows isn't starting, the boot options should open up automatically after 2-3 attempts.
In the boot options, go to Troubleshoot > Advanced options > Startup Repair.Then, just click on the "Startup Repair" option and it will automatically scan and fix any startup problems.


5. Task Scheduler
This is one of the most powerful tools that Windows has to offer, but it's often neglected. The Task Scheduler allows you to schedule important tasks and evenhandle daily tasks automatically without manual intervention from your side.
You can start up a program, use Window functions, send emails or simply show an important message at a specific time or as a response to a specific event (for example, logging in). Want to scan your computer once a week with your antivirus program? Task Scheduler can do that for you.
If you want to take advantage of this tool, you can find it under Administrativetools or you can type "taskchd.msc" in the "Run" dialog.
To get started, click on the "Action" menu at the top and then select "Create Basic Task." A wizard will pop up and guide you through how to schedule a task.


6. Reliability Monitor 
This is kind of like the Event Viewer tool, but it's very easy to read and only lists problems that are harmful.
If you have recently been having problems with an application or Windows, then the Reliability Monitor may be able to help.
To access this tool, go to Control Panel > System and Security > Security and Maintenance. Click on "Maintenance" and select "View reliability history."
Reliability Monitor will provide a performance graph over time complete witherrors and problems listed under each day. You can then click on a day to see all the errors or events, and double clicking an errors will provide more details and solutions.


7. Memory Diagnostic 
You don't need someone else to check whether the memory (RAM) of your PC is working or not, as Windows has a built-in Memory Diagnostic tool that does it for you. It will scan your computer for any memory issues and let you know of bad memory.
Note: A Memory Diagnostic scan requires your PC to restart. So save everything before using this function.
To access this tool, type "mdsched.exe" in the "Run" dialog and hit enter. You will then be asked whether you'd like to "Restart" and scan the PC. Choose the appropriate option and your PC will restart then start the Memory Diagnostic scan.
Once it has been completed (5-10 minutes usually), your PC will restart and you'll get a diagnostic report when you login.
