Ju-Seo-Gwan-Gyeon is a mathematical book of Chosun dynasty in the early 18th century. This study is to analyze and compare the contents between Ju-Seo-Gwan-Gyeon and Gu-Jang-San-Sul. From this study, we are able to see the contents of Ju-Seo-Gwan-Gyeon that has been unknown in detail so far. In this comparative study, the following facts are found. First, many problems in Ju-Seo-Gwan-Gyeon are similar to the Gu-Jang-San-Sul on the contents and frame. Most of them are same type. But some of problems in Ju-Seo-Gwan-Gyeon have been developed. Second, there are distinct differences of description type. And Ju-Seo-Gwan-Gyeon was influenced by Gu-Jang-San-Sul but also other mathematical books. We expect that the results provide basic information for mathematics history in Korea.

Ju-Seo-Gwan-Gyeon is a mathematical book of Chosun dynasty by Jo Tae Gu. This study is to analyze his understanding for the 'Gujang' in the 'Gujang-Mundab'. From this study, we were able to see the contents of 'Gujang-Mundab' that has been unknown in detail so far. In this study, the following facts are found. Most parts of 'Gujang' in 'Gujang-Mundab' was explained the same as Gu-Jang-San-Sul. This indicates that Ju-Seo-Gwan-Gyeon was influenced by Gu-Jang-San-Sul. However, Ju-Seo-Gwan-Gyeon also contains what he wrote with his own understanding. We expect that the results provide basic information for mathematics history in Korea.

The character of Plain Weaved Silks at the end of the Joseon Period from Takjijunjeol(탁지준절) are as follows. 1. Plain Weaved Silks recorded in Takjijunjeol(탁지준절) are Ju(주) 22 types, Cho(초) 13 types and Gyeon(견) 3 types. This is same as previous research where Ju(주) and Cho(초) were subdivided and diversified at the end of Joseon Period, but Gyeon(견) gradually disappeared, leaving only Ju(주) and Cho(초) 2. Plain weaved silks whose character have been examined are Gajiju(개지주), Nujuju(노주주), Nobangju(노방주), Bangsaju(방사주), Simnyangju(십량주), Hapsaju(합사주), Suju(수주), Toju(토주), Sukcho(숙초), Ryeoncho(연초), Gungcho(궁초), Byeol$$\mu$goyeongcho(별문고영초), Hujigyeon(후지견), 3. According to the differences in values and value scales written in Takjijunjeol(탁지준절), Ju(주) had various kinds of silks and Ju(주) are classified by qualities into two groups, the higher qualified group A or the lower qualified group B. On the contrary, Cho(초) and Gyeon(견) had only a few kinds, not as many as Ju(주), but all were high quality. Among them the most valuable plain weaved silks were Seoyang$$\mu$ju(서양문주), Hapsaju(합사주), Byeol$$\mu$goyeongcho(별문고영초). 4. According to Pobaekcheok(포백척) of Takjijunjeol(탁지준절) which shows real sizes, Ju(주) had various length and widths, but Cho(초) had one unified length and width.

The objective of this study is to report the improved case of Achilles tendinitis treated with Korean medicine, Gyeon-mak chuna and Graston Technique. The patient diagnosed with Achilles tendinitis is hospitalized at Department of Korean Rehabilitation Medicine, Samse Hospital of Korean Medicine. The subject is treated by herbal medicine, acupuncture, Gyeon-mak chuna and Graston technique. This study was measured by Visual Analogue Scale (VAS) score, walking time without pain per 6 minutes (6MWT) and American orthopaedic foot and ankle society Hind foot scale (AOFAS). The patient showed decreased VAS, AOFAS and improved 6MWT after treated with Korean medicine, Gyeon-mak chuna and Graston Technique. The patient showed reduced pain and positive effect on activities of daily living.

In this study, the scientific description of Earth was analyzed by targeting the item titled '1. Introduction to the Earth World', which is part of the 'first section' of SeoYuGyeonMun(西遊見聞) written by Yu Giljun(俞吉濬). This part served as an introduction to the entirety of SeoYuGyeonMun. It was also one of the earliest documents in Korean literature to mention 'the earth as a celestial body', rather than solely focusing on it as land which was a departure from traditional thinking. Yu Giljun made deliberate efforts to translate the concept of Earth's rotation into "Jashinjeon(自身轉)" and Neptune as "Haeryongseong(海龍星)". He included the latest scientific debates and facts in SeoYuGyeonMun, such as the theories of Western scholars explaining the types of seismic waves and discussions at international conferences related to the establishment of the original meridian. Yu Giljun, who was not a science major, would have used HunMongGungRiDoHae(訓蒙窮理図解, 1868) written by Fukuzawa(福澤諭吉) and GeokmulJiji(格物地誌, 1876) which was translated by Matsumoto(松本駒次郎) as references to describe scientific descriptions. The contents described in 'Introduction to the Earth World' cover the foundational composition and subject matter that are typically found in modern-day Earth science textbooks.
