今回われわれは,原発性肺癌疑いの精査でCT検査を行ったところ甲状腺に腫瘍を認め,穿刺吸引細胞診の結果悪性腫瘍と診断し,摘出術を行った。病理組織学的結果は,肺癌からの転移性甲状腺癌と診断した症例を経験した。転移性甲状腺癌は進行すると,呼吸や摂食に関係し,その後患者のQOLを著しく低下させるため,原発腫瘍の治療状況,全身状態,PS,腫瘍を摘出してその症例のQOLが向上するかどうかを総合的に判断して治療にあたるべきと考えられた。本症例のように急激な増大を認める症例もあり摘出時期を逸しないことも重要と考えられた。

Radiological technologists (RTs) and medical technologists (MTs) are legally allowed to work as sonographers performing medical ultrasound examination. Despite the total number, much fewer RTs work as sonographers than MTs. To explore the reason, we investigated educational programs, universities, and colleges for both specialties. First, we established five categories of sonographers’ competency: 1) Anatomy for imaging diagnosis, 2) Diseases and diagnosis, 3) Imaging, 4) Structure and principle of the equipment, and 5) Evaluation of image quality, using competence reported by the International Society of Radiographers and Radiological Technologists (ISRRT) and diagnostic competency required of sonographers in Japan. Using these categories, we analyzed the content and total instruction time by lectures and seminars based on information written in the syllabi, and explored the differences in education related to sonographers’ competency in both programs. “Anatomy for imaging diagnosis” was taught in 15 RT programs (93.8%), and 6 MT programs (31.6%). “Diseases and diagnosis” was taught in 13 RT programs (86.7%), and 8 MT programs (53.3%). “Imaging” was taught in 14 RT programs (100%), and 13 MT programs (76.5%). “Structure and principle of the equipment” was taught in 12 RT programs (85.7%), and 6 MT programs (31.6%). “Evaluation of image quality” was taught in 11 RT programs (84.6%), and 3 MT programs (15.0%). The average instruction time for RT was longer than for MT programs in all categories. RTs are educated and have a foundation to be sonographers at graduation, and may have the possibility to expand their career in this field.

In France the educational policy for children of immigrants and foreigners began to be formed in the 1970s.That was aimed to adapt them to French society and school through their learning French.In the 1980s the policy for ‘right to be different’ attracted an attention of the public in the dominant political power of the Socialist Party.But for many foreign children born in France the policy of ‘adaptation’ and ‘admitting difference’ is not necessarily relevant.Presently the policy of ‘integration’ is being adopted to make the French society through participation and solidality of all people.

Dual Phase (DP) steel is used in automotive body parts for weight saving and crashworthiness, however there is an issue of DP steel in low stretch flange ability evaluated by hole expanding tests. In order to improve stretch flange ability of DP steel, it is important to estimate the damage of punching quantitatively and to clarify the change of microstructure before and after punching because the hole expansion ratio is decided in the ductility remained after pre-strain equivalent to punching. Therefore we tried to measure the damage of punching by unique techniques of Electron Backscatter Diffraction (EBSD), nano-indentation and micro-tensile testing and to observe fracture surface by Scanning Transmission Electron Microscope (STEM). Average EBSD-Kernel Average Misorientation (KAM) value and pre-strain damage have strong correlation, thus average KAM value can become the index of the damage. The nanohardness and tensile strength using micrometer-sized specimens increased with increasing average KAM value in the ferritic phase as approaching the punching edge. A shear type fracture occurred without necking in the specimen cut out in the area of the edge. The ultrafine-grained ferritic microstructure was observed in the sample cut out in the same area with STEM. It seems that the ductility loss of the punched DP steel was probably attributed to localized strain into the ultrafine-grained ferritic microstructure.
