Treatment of perianal and vulvar extramammary Paget disease (EMPD), rare intraepithelial malignancies, is often challenging because of its potential to spread into the anal canal. However, there is still no consensus regarding the optimal resection margin within the anal canal. Between 2004 and 2014, six patients (three with perianal EMPD and three with vulvar EMPD) in which the spread of Paget cells into the anal canal was highly suspected were referred to our department. To evaluate the disease extent within the anal canal, preoperative mapping biopsy of the anal canal was performed in five out of six patients. Two patients were positive for Paget cells within the anal canal (one at the dentate line and the other at 0.5 cm above the dentate line), whereas in three patients, Paget cell were present only in the skin of the anal verge. Using 1 cm margin within the anal canal from the positive biopsy sites, we performed anal-preserving wide local excision (WLE), and negative resection margins within the anal canal were confirmed in all five patients. The remaining one patient with perianal EMPD did not undergo mapping biopsy of the anal canal because preoperative colonoscopy revealed that the Paget cells had spread into the lower rectum. Therefore, WLE with abdominoperineal resection was performed. During the median follow-up period of 37.3 months, no local recurrence was observed in all patients. Our small case series suggest the usefulness of mapping biopsy of the anal canal for the treatment of perianal and vulvar EMPD. (Ann Dermatol 28(5) 624∼628, 2016)
Estimations of Regional Stress Based on Measured Local Stress
( Yuzo Obara ),( Katsuhiko Kaneko ),( Seong Seung Kang ) 대한지질공학회 2016 지질공학 Vol.26 No.2
Estimations of regional stress are demonstrated in this paper. Firstly, regional stress is defined and the characteristics of regional stress are then discussed based on the local stresses measured by the Compact Conical-ended Borehole Overcoring (CCBO) technique and the results from the earthquake focal mechanism. Secondly, the regional stresses are estimated by a back analysis of three-dimensional finite element models, using the local stresses measured by the CCBO and hydraulic fracturing.
Trusting rather than Understanding Others : Another Intercultural Cosmopolitan Education
Yuzo Hirose 인하대학교 다문화융합연구소 2019 다문화와 교육 Vol.4 No.1
The purpose of this study is to suggest a practical model of cosmopolitan education on the basis of the trust of others with culturally different backgrounds. To this end, this study used literary review as research method. First, this study provided the theoretical overview of discussion and problem on classical cosmopolitan education. And furthermore, this study dealt with a uniqueness of trust in educational context as an asymmetrical power of human formation. Lastly, this study concluded that trusting others with different cultural backgrounds can be a practical training to be a cosmopolitan. Thus, this study contributes to the extension of discussion of cosmopolitan education and provides practical implications in cosmopolitan education
Selenium Content of Infant Formulas and Estimated Intake of Infants in Japan and Korea
Yuzo Tamari,Eul-Sang Kim,Kyu-Han Lee 한국식품영양과학회 1998 Preventive Nutrition and Food Science Vol.3 No.3
Selenium contents of infant formulas that were commercially available in Japan and Korea were determined by the method of atomic absorption spectrometry with hydride generation. Total means of selenium contents were 45.2±22.1 ng/g (n=34) in all the Japanese formulas and 58.3±18.9 ng/g (n=22) in all the Korean formulas. Selenium contents of milk-based formulas (54.7±23.2 ng/g in Japan, n=20 and 64.8±12.6 ng/g in Korea, n=18) were significantly higher than those of soy-based formulas (36.8±10.2 ng/g in Japanese brands, n=3 and 26.6±16.2 ng/g in Korean ones, n=3) and special-use fomulas (30.1±11.0 ng/g in Japanese brands, n=11 and 36.4 ng/g in Korean one, n=1). Based on selenium data of these formulas the selenium intakes of infants have been estimated to be about 6.6 ㎍/day in Japanese and 8.1 ㎍/day in Korean by milk-based formula feeding.
