<Articles>The Kyoto School's Dojo of Philosophy (The 6th International Symposium between the Graduate School of Education, Kyoto University (Japan), and the Institute of Education, University of London (UK))

During an internet search a year ago I was surprised to learn of a new anthology entitled Education and the Kyoto School of Philosophy. I really should not have been surprised, because after all the Kyoto School philosophers were educators, almost all of them university professors, mostly at Kyoto University. Later in the fall, when I perused titles in the philosophy section of major book stores in Tokyo and Kyoto, I found an abundance of books on Nishida Kitarō and the Kyoto School, ranging from detailed analyses of Nishida's works to political critiques and even a wide-ranging exploration of the Kyoto School and ecology. Given the scope of trends in academic publishing today, one might expect to see topics of this sort treated from various points of view. But the seemingly obvious theme of education was missing among the numerous books in Japanese, and so it is all the more significant that the editors of this anthology in English recognized the relevance of the Kyoto School for education

Radiation therapy planning for early-stage Hodgkin lymphoma: experience of the International Lymphoma Radiation Oncology Group.

Early-stage Hodgkin lymphoma (HL) is a rare disease, and the location of lymphoma varies considerably between patients. Here, we evaluate the variability of radiation therapy (RT) plans among 5 International Lymphoma Radiation Oncology Group (ILROG) centers with regard to beam arrangements, planning parameters, and estimated doses to the critical organs at risk (OARs).Ten patients with stage I-II classic HL with masses of different sizes and locations were selected. On the basis of the clinical information, 5 ILROG centers were asked to create RT plans to a prescribed dose of 30.6 Gy. A postchemotherapy computed tomography scan with precontoured clinical target volume (CTV) and OARs was provided for each patient. The treatment technique and planning methods were chosen according to each center's best practice in 2013.Seven patients had mediastinal disease, 2 had axillary disease, and 1 had disease in the neck only. The median age at diagnosis was 34 years (range, 21-74 years), and 5 patients were male. Of the resulting 50 treatment plans, 15 were planned with volumetric modulated arc therapy (1-4 arcs), 16 with intensity modulated RT (3-9 fields), and 19 with 3-dimensional conformal RT (2-4 fields). The variations in CTV-to-planning target volume margins (5-15 mm), maximum tolerated dose (31.4-40 Gy), and plan conformity (conformity index 0-3.6) were significant. However, estimated doses to OARs were comparable between centers for each patient.RT planning for HL is challenging because of the heterogeneity in size and location of disease and, additionally, to the variation in choice of treatment techniques and field arrangements. Adopting ILROG guidelines and implementing universal dose objectives could further standardize treatment techniques and contribute to lowering the dose to the surrounding OARs
