Yoshitoshi Tokugawa is a military man who contributed to the development of Japan’s aviation field from the Meiji era to the Showa era. He was born as the eldest son of Atsumori Tokugawa, the 7th head of the Shimizu Tokugawa family of Gosankyo Tokugawa. After studying at the elementary and junior high schools attached to the Higher Normal School (currently the elementary and junior high schools attached to Tsukuba), he became a captain of the Army Engineer in 1909 after attending the Imperial Japanese Army Academy. The following year, in 1910, Yoshitoshi was sent to France for specialized education by ordering the Army to acquire maneuvering skills with Ensign Hino Kumazo Infantry and to purchase the aircraft. At that time, the development of aircraft was remarkable in Europe, so the arrow of white feathers struck. He returned to Japan after becoming the first Japanese pilot. On December 19, the same year, at Yoyogi Training Ground (currently Yoyogi Park), Japan’s first aircraft-powered flight (altitude of about 70 meters, distance of about 3000 meters) was driven by Kaishiki No. 1 (Henri Farman biplane). success. At the Army Tokorozawa Airfield (currently Tokorozawa Aviation Memorial Park), Japan’s first aircraft-only airfield completed in 1911, an exhibition flight is being held to commemorate its completion. After that, he continued to walk in the aviation field, and after the aviation department became independent, he changed from the engineering department and focused on training younger generations. Although he left active duty for a while, he was the head of the Imperial Japanese Army Air Academy at the end of the war. His final rank is Lieutenant General of the Army, and in 1928 he was awarded the Baron’s title for his many years of achievement. Kumazo Hino is a military and aviation engineer who was active from the Meiji era to the Showa era. He was born in Kumamoto prefecture in 1878 as a child of the former Sagara clan, and grew up to go to the Imperial Japanese Army Academy. After graduating, he belongs to the Army Infantry Department and seems to be involved in weapons research at the Technical Examination Department. In 1910, he studied at “Henri Farman” Flight School Etampes in France with Captain Yoshitoshi, but the purchase of the aircraft was unsuccessful, and Kumazo negotiated with Germany alone to purchase a grade monoplane and returned to Japan. On December 19, the same year, Kumazo and Yoshitoshi challenge Japan’s first powered flight. His aircraft is a grade monoplane that he bought himself, and it is a compact aircraft with half the weight and engine output of “Henri Farman” (the cockpit is also used as an landing wheel rack and is suspended directly under the main wing, and it is in a low position just above the ground.) Fly a distance of about 1000 meters. It seems that he was applauded by the audience, which was said to be over 100,000. After that, he focused on the field of technology development such as developing Hino-style airplanes by his own design, and in addition to aircraft-related technologies such as control equipment, he also obtained patents for firearm design represented by Hino-style pistol. leave. His final rank is Lieutenant Colonel Infantry, and after his retirement he has been challenging technological development in the fight against his poverty and his own illness. 10 years number of clear days from 2009 to 2018-In total, it has 567 days and is the number one in Japan. 170 km-Japan’s longest cycling road runs along the river and The ratio of terrain area with gentle slope is the highest in Japan.

Do not leave what you have dug out.（COOH-COOH: A general term for a series of organic compounds having a carboxy group. It is a basic chemical structure contained in various functional molecules including biomolecules such as amino acids and fatty acids. It is a well-known fact that carboxylic acids are used in many of the medicines and pesticides currently on the market. Researchers say that if the carboxy groups of these carboxylic acids can be replaced with other functional groups, new molecules useful for life science research and drug discovery research can be easily synthesized from existing carboxylic acids. However, since the carboxy group is incorporated into the carboxylic acid by a strong carbon-carbon bond, it seems that it is not easy to break the bond. It seems that there is an unreasonable problem that a high temperature of 150 ° C or higher is required to break the bond by the existing method, the target molecule cannot be sufficiently obtained due to the influence of the side reaction due to heat, and the applicable carboxylic acid is limited); Oxalic acid and other harshness will increase, so it is recommended to remove it as soon as possible.
The description of a long-jointed bamboo can be seen in “Kojiki”, and it seems that it has been eaten for a long time. Bamboo shoots currently in circulation are mainly native to China called moso bamboo. It seems to be derived from the fact that a filial son named Meng Zong of China pleased her mother by digging up and collecting snow for her sick mother in the middle of winter. It is said that in the middle of the Edo period, Yoshitaka Shimazu (1675-1747, a direct ancestor of Emperor Imagami), the 21st feudal lord of the Shimazu clan, took it back from Ryukyu and planted it in the feudal lord’s residence. It grows a lot in warm regions, and I hear that there are about 150 species (depending on the theory) in Japan. Of these, only a few are edible, such as Moso bamboo, Lophatherum gracile, and Matake.
Bamboo shoots are characterized by their extraordinary growth potential, which grows several centimeters a day, and it is known that this is because the growth factor called tricontanol contained in the outer skin promotes growth. As for the nutritional components of this excellent agricultural product, carbohydrates, proteins, fats, etc. are contained as much as onions, radishes, and cabbage, and it seems that vitamin B12, which improves the complexion, is also contained. Dietary fiber is a heterocyclic amine (a powerful mutagenic substance (which damages genes and causes mutations) that leads to the induction of liver cancer, including intestinal regulation, and its mutagenicity is typical. Aflatoxin, a carcinogen (researched in the wake of the death of more than 100,000 turkeys in the United Kingdom in 1960. The causative agent was the Aspergillus flavus: a type of Koji mold. , Toxin produced by Aspergillus flavus (a substance having a highly toxic biological protein structure, named aflatoxin because of its antigenicity (characteristic that causes a living body to produce a specific antibody). In subsequent research, Aspergillus parasiticus It has been found that aflatoxin is also produced. There are known types of this substance such as aflatoxin B1, B2, G1, G2, and M1. Among them, aflatoxin B1 is a natural and most powerful carcinogen. Known) and C20H12 (typical carcinogenic polycyclic aromatic hydrocarbons (having 5 benzene rings), also known as 3,4-benzopyrene, pale yellow crystals or powders. In addition to being present in coal tar, which is a by-product of producing corks from coal, it is also contained in automobile exhaust gas and tobacco smoke, and is a substance that is unintentionally produced by combustion of fuel and the like. It seems that no environmental standards have been set, but it has been selected as one of the 234 substances that may fall under the category of harmful air pollutants, and among them, it is one of the 22 “priority action substances” that have a high health risk to some extent. Twenty-three heterocyclic amines have been found so far, some of which have been reported to be carcinogenic in rats, mice, monkeys, etc., while epidemiological studies It has been pointed out that ingesting more charcoal increases the risk of carcinogenesis, but it seems that it is not fully clear whether heterocyclic amines are directly responsible for carcinogenesis in humans. Clarifying how much heterocyclic amine is taken is very important for assessing carcinogenic risk). It seems that recent studies have also revealed the effect of adsorbing it.
