I continued this research and eventualy made it the thesis of my graduate research.<br \/>\nBy looking at the earth as a ellipsoid revolution, rather than viewing it as spherical, a more accurate map can be prepared.<br \/>\nThere are many difficult theorums and calculations regarding the theory of the geodesic line, which is the shortest route on a bent surface, and the theory of map projection.<br \/>\nI felt rewarded in my research when I was able to clearly define a theorem proof, and by changing my viewpoint I realized that there are other proofs as well.<\/p>\n<\/div>\n<p><!--\n\n\n<div class=\"area_message_t area_message_dept-1\">\n\n\n<div class=\"message_photo\"><img loading=\"lazy\" decoding=\"async\" src=\"\/\/www.st.hirosaki-u.ac.jp\/wp-content\/uploads\/faculty\/data\/photo_dept-1-t2022.jpg\" alt=\"\" width=\"150\" height=\"180\" \/><\/div>\n\n\n\n\n<div class=\"message_text\">\n\n\n<p class=\"p_MT_advice\">Advice<\/p>\n\n\n\n\n<p class=\"p_MT1\">\n\n\n\n\n<p class=\"p_MT2\">Associate Professor SENDOUDA, Yuuiti<\/p>\n\n\n<\/div>\n\n\n\n\n\n\n\n<\/div>\n\n\n--><br \/>\n<\/section>\n<section>\n<h2>Staff List<\/h2>\n<h3>Mathematics<\/h3>\n<table class=\"table_grad grad-1\">\n<tbody>\n<tr class=\"add_bg1\">\n<th style=\"width: 10em\">Name<\/th>\n<th style=\"width: 5em;\">Position<\/th>\n<th style=\"width: 14em;\">Specialty<\/th>\n<th>Research Content<\/th>\n<\/tr>\n<tr>\n<th class=\"add_bg_dept-1\"><a href=\"https:\/\/hue2.jm.hirosaki-u.ac.jp\/html\/532_en.html\" target=\"_blank\" rel=\"noopener noreferrer\">KON, Masamichi<\/a><\/th>\n<td>Professor<\/td>\n<td>Operations Research<\/td>\n<td>Planning mathematics are used to solve various social problems.
