Chosun dynasty mathematician Park Yul (1621 - ?) wrote San Hak Won Bon(算學原本) which was posthumously published in 1700 by his son Park Du Se (朴斗世). It is the first mathematics book whose publishing date is known, although we have Muk Sa Jib San Bub (默思集算法) by Gyung Sun Jing (慶善徵, 1616-?). San Hak Won Bon is the first Chosun book which deals with tian yuan shu (天元術) and was quoted by many Chosun authors. We do find it in the library in Korea University. In this paper, we investigate its contents together with its historical significance and influences to the development of Chosun dynasty Mathematics and conclude that Park Yul is one of the most prominent Chosun dynasty mathematicians.

Objectives : This study aims to evaluate the effectiveness of incisional needle therapy, a type of Korean medicine treatment, on atrophic scars caused by herpes zoster and varicella. Methods : The patients with atrophic scars resulting from herpes zoster and varicella were treated with incisional needle therapy and the effectiveness of the treatment was evaluated with Physician's Global Assessment (PGA) and The Stony Brook Scar Evaluation Score (SBSES). Results : After treatment, all patients demonstrated improvements in PGA and SBSES. The PGA score improved to 3.73±0.40, with SBSES changing from 1.60±0.60 to 4.80±0.80. Conclusions : We suggest that incisional needle therapy demonstrates effectiveness in treating scars resulting from herpes zoster and varicella, indicating its potential as a viable therapeutic option for individuals affected by these conditions.

1. Objective This study is about a Soeumin patient who had Yul Gyuk similarity with anorexia, nausea, sialism. In this study, we report the effects of Sasang constitutional treatment to this patient. 2. Methods This patient was treated by Soeumin's constitutional medications and acupunture according to the result of Sasang constitutional diagnosis. 3. Results and Conclusions This patient's chief complaints were anorexia, nausea, and sialism. By using Gyejibanhasaenggang-tang mainly, he showed positive response about his symptom. This study shows that Gyejibanhasaenggang-tang has effect to Yul Gyuk similarity in Soeumin.

Objectives : The purpose of this study is to present the effect of subcision, microneedle therapy system and herbal peeling therapy which is treatment of Korean medicine to atrophic acne scar patients. Methods : We administered subcision, microneedle therapy system and herbal peeling therapy to atrophic acne scar patients and tested the results by Qualitative Global Acne Scarring Grading System and Korean Acne Grading System as well. Results : After the treatment, all of the patients showed improvements in Qualitative Global Acne Scarring Grading System and Korean Acne Grading System as well. Qualitative Global Acne Scarring Grading System of patients changed from grade 2.71±0.71 to grade 1.14±0.86 along with the change of Korean Acne Grading System from grade 1.57±0.57 to grade 1.00±0.00. Conclusions : Subcision, microneedle therapy system and herbal peeling therapy may be effective in the treatment of moderate to severe acne scars, and could be applied in clinical practice.
