Most people who traveled to a place they were not familiar with brought maps on their trips. There are two types of maps: digital maps and paper maps. For some people, digital maps are more convenient. They cover larger areas and are more accurate. They can tell users when to turn left or right. There is also an option to zoom in or out the maps. They can also provide the best way to get to the destination. For example, digital maps can tell how much time it will take if a person takes a taxi or a train. However, some people still prefer to use paper maps as they can still use it even without an internet connection.

Dolphins communicate with one another in different ways. Some of which are by creating sounds and using body language. Each dolphin produces various sounds which allows them to identify which is which.

Dolphins usually create high or low sounds and measure the time it takes to bounce off of nearby objects and back to them. This is called echolocation. Through this, dolphins can tell how far an object is and which direction it is traveling in. Echolocation is essential to dolphins as their ability to see underwater is often limited. It helps them find food and avoid possible dangers.

Another important thing for dolphin’s survival is body language. They use different body language signals to communicate with one another and observe their surroundings. Some of the movements they often use are spy hopping, tail slapping, jumping, and bumping to each other.

Spy hopping is when a dolphin’s head is partly above the water for a period of time while keeping its eyes above or below the water. They do this to stay alert of their surroundings. On one hand, tail slapping is used to look out for any signs of danger. On the other hand, It could be a sign of playful communication depending on how loud the slaps are.

Dr. Kanto Tomoko was assigned to work in Madhu. For her, the most difficult thing about being a doctor in Madhu was making decisions. It is important for them to consider local situations. Basing their decisions on Western or Japanese perspective could lead them to even more difficult situations. Having limited equipment was also a challenge, so they had to carefully think about every situation to make the best decision.

Dr. Kanto remembered the day when a five-year-old boy was brought to their hospital. She knew immediately that his condition was beyond help. He was pale due to difficulty in breathing, so she gave him oxygen. However, his condition did not improve. Unfortunately, that oxygen tank was their last one and they had no idea when the next one would arrive. She realized that if another patient needed oxygen, this tank could save his or her life. So, she decided to turn off the oxygen tank. No one could tell if that was the best decision to make, not even Dr. Kanto. But she believed that it was best to leave the child in God’s hands.

Being a volunteer doctor gave more meaning to her life. She hopes that more Japanese people will do volunteer work. Dr. Kanto plans to continue helping people until it is no longer necessary.
