Antipersonnel mines are planted under the ground and explode when they are stepped on. They were invented to kill and injure people during the war. Many of their victims suffered to death or live in misery.

Mines remain active for a very long time. In fact, they can last even a century. There were about 50 million mines found in 2001. Because of that, the government, together with some NGOs, has been making an effort to remove them without harming anyone.

In 1999, more than 150 countries have signed the Ottawa Treaty. Their goal is to end the use of antipersonnel mines. The clearing operation requires a large number of people to work together to turn it into a success.

Hirose Shigeo published a research paper in 1996 that talks about mine-removing robots. Since 1990, he has been helping in removing mines with the use of the robots he created. The first robot he developed was called Titan X. It is expected to locate and remove mines with its four legs that can walk around rocks. Meanwhile, Hirose has been developing a snake-type robot that would help find mines by going through bushes without any pressure so that mines would not explode.

Humans, with the help of technology, have invented things that make their lives more convenient. For instance, they have designed airplanes and trains that allow them to travel to far places for a shorter period of time. They have also created mobile phones that let them receive information and communicate with other people as quickly as possible. Another important invention is medicines which they use to treat different diseases. However, most of these inventions have negative effects on the environment.

According to Janine Benyus, humans should help save the environment by observing and trying to find inspiration from nature. She also said that by doing so, people could learn how to live in a nature-friendly way.

A famous example of biomimicry is the Shinkansen trains in Japan. When Engineers first made the Shinkansen, the trains made a very loud sound when going into tunnels which became a huge problem. The engineers found the solution through kingfisher, a kind of bird that dives into the water without a splash. They designed the nose of the train just like the beak of a kingfisher.

Benyus believes that through biomimicry, people would become more aware of nature that will eventually help them save the environment.

Tokyo has an excellent transportation system which includes trains, subways, buses, and taxis. The two best ways to get around Tokyo are trains and subways which are connected to each other. The “Tokyo Loop Line” is the most useful train line which could be used if one is planning to visit Shinjuku. The fare could be paid using subway passes or prepaid cards. Since subways and trains are more convenient, very few people use the Tokyo Bus system. So, it is good for people who like less-crowded vehicles. The bus fare could be paid using One-Day Bus passes or prepaid cards and in cash through fare machines. Taxis in Tokyo are easy to catch so it is convenient for people who have luggage. However, the fare is quite expensive which could be paid in cash or credit card. For example, if one is going to Shinjuku Station from Tokyo Station, it will cost around 3,500 yen.

Getting around Tokyo is a great experience. Choosing the right transportation system is important so that one could enjoy getting around Tokyo.

In 3rd century B.C., the first known museum was opened in Egypt. Since then, museums could be found in any country around the world. Museums have set a traditional purpose in collecting and preventing damages on objects and materials with historical importance. Museums are also in-charge of research and presentation of the historical materials for entertainment and education purposes.

In the early days, museums were not open to the general public. Only the rich and educated people could visit museums, so most people were not interested in exploring them. However, as time pass, people realized and suggested that museums should be more open to the public, especially to children because it is a way for them to learn from the past.

Museums are important in promoting cultural education. Through the presentation of historical objects, people could recognize the differences between facts and opinions about history. Nowadays, museums improve modern education by letting people to take part in knowing the facts in history and assisting future generations to appreciate their culture.

Biology is the study of living things. Its name comes from the Greek words “bios” which means life, and “logos” which means study. Biology aims to understand the structure, function, and origin of all living things.

Up to this day, it is still a question when and how the study of biology began. However, it is believed that early humans had knowledge of animals and plants around them as they were significant for human survival.

Biology is divided into different branches. Some of which are anatomy, botany, and ecology. Anatomy deals with the structure and parts of living things. It is divided into three areas. The first one is the human anatomy which is responsible for the human body and its structure. Second, zootomy which focuses on the structures of the animals. The last one is phytotomy which deals with the internal structures of plants.

Meanwhile, botany is the scientific study of plants. It includes its structure, properties, types, and environmental impact. Theophrastus, a Greek philosopher, is considered as the father of botany.

On the other hand, zoology which is also known as animal science is responsible for the study of animal life. A Greek philosopher named Aristotle is considered to be the first to practice scientific zoology.

Biology is important not only to humans but to all other living things. It helps people understand their surroundings and how they are connected with one another. In addition to that, it provides a significant contribution to sustain human life and the environment.

Nowadays, a lot of companies have been doing business abroad. However, there are cultural differences that businesspersons should be careful about.

In the U.S., it is very common to have a small talk regarding personal life before starting a meeting. Meanwhile, in some cultures, talking about personal life may be seen in a bad way as it is considered wasting time. Another example of cultural differences is about being confrontational. In North and Latin America, businesspersons usually say things directly and are used to confrontations. However, in Asia, they are usually more collaborative and usually not comfortable taking an action that might hurt other people.

Speaking different languages could also be one of the biggest problems business people may encounter when dealing with foreign companies. So, it is important to keep their speech simple and direct to the point. Avoiding fancy words might also come in handy. A simple speech would help minimize miscommunication.

It is also important to be mindful of their actions. In Western countries, eye contact is normal. However, in most Asian countries, it is considered rude.

How businesspersons deal with their clients might significantly affect their business. So, they have to keep in mind that they should consider the cultural differences to keep a good working relationship with their foreign clients.

Smartphones have changed how people communicate. Through modern technology, smartphones have been gaining more and more uses every day. However, the smartphone has its own advantages and disadvantages. One of the advantages of having smartphones is faster communication. People can send text messages anywhere across the world in less than a second. In addition to that, people can do video calls to see the person on the other line. Having a smartphone could also have a disadvantage such as decreased face-to-face communication which often leads to arguments. Nowadays, many people use smartphones to play games, so they do not have much time for face-to-face conversations. People should not forget these advantages and disadvantages for them to be responsible smartphone users.
