This study investigates the necessity for space robots to independently exchange their end-effectors due to the contradiction that exists between the requirements of various robots in space missions and the payload capacity limits of rockets. The results of this study summarize the system requirements for a new end-effector exchange mechanism, including compact size, misalignment tolerance, and regolith tolerance. This is followed by the development of a prototype model with a set of test apparatus. Then the function of the prototype is verified, the prototype is optimized, and the relation between docking force and misalignment is examined through operation tests.

Supernumerary tooth in the upper central incisor region is called mesiodens. Mesiodens causes serious complications such as displacement, retarded eruption, and rotation in the adjacent permanent incisors, inducing inhibition of oral development. This report was aimed to provide epidemiology of mesiodens in Japanese children. Using dental record, panoramic radiographs and images of cone-beam computed tomography in 128 non-syndromic child patients, patients’ age at their first visit, gender composition, shape of mesiodens, position of mesiodens, posture of mesiodens, and age distribution of the patients based on each complication were investigated. In addition to the survey, patient age was compared between the groups with and without each complication. Patients’ age ranged 3 - 10 years old. Male-to-female ratio was approximately 3:1. Conical shape (75%) and inverted position (49%) were the most frequent among the patients. Displacement was the commonest complication. Age comparison indicated that patients with displacement or retarded eruption consulted the dentist younger than those without the complications. The present study provided etiology of mesiodens in Japanese children that will contribute to daily clinical practice in the field of pediatric dentistry.

Objective: Nalebuff’s type I deformity of the rheumatoid thumb, which is the most common thumb deformity with rheumatoid arthritis, can be classified into three stages according to the range of motion of the thumb. However, a functional assessment for each stage has never been undertaken. Methods: The ranges of motion of the thumb metacarpophalangeal and interphalangeal joints were evaluated to determine Nalebuff’s clinical stage, and both the Modified Kapandji Index (MKI) and the simple test for evaluating hand function (STEF) were used to evaluate hand function in 32 rheumatoid arthritis patients with type I deformity. We assessed hand function in each stage, and examined the relationship between the three clinical stages and dysfunction of the hand. Results: The scores for both MKI and STEF were significantly reduced in parallel with advancing stage of thumb deformity. Conclusion: Nalebuff’s staging system is also useful for reflecting the level of thumb function.

The link between income inequality and obesity inJapanwas evaluated. Income inequality of all 47 prefectures of Japan as expressed by Gini coefficient was obtained from National Statistics Center, Japan. The rate of obesity (%) was also obtained from National NutritionSurvey,Japan. The effect of income inequality on obesity was evaluated by ecological study. Income inequality as expressed by Gini coefficient was 0.31 ± 0.01 and the rate of obesity was 31.6% ± 5.6%. Gini coefficient was significantly and positively correlated with the rate of obesity (r = 0.490, p = 0.0005). Income inequality was might be associated with the rate of obesity inJapan.

Neuroendocrine carcinoma(NEC) originating from the gastrointestinal hepatobiliary-pancreas is a rare, invasive, and progressive disease, for which the prognosis is extremely poor. The patient was a 72-year-old man referred with complaints of jaundice. He was diagnosed with middle extrahepatic cholangiocarcinoma(cT 4N1M0, c Stage Ⅳ). He underwent a right hepatectomy combined with extrahepatic bile duct and portal vein resection after percutaneous transhepatic portal vein embolization. Microscopic examination showed a large-cell neuroendocrine carcinoma according to the WHO criteria for the clinicopathologic classification of gastroenteropancreatic neuroendocrine tumors. Currently, the patient is receiving combination chemotherapy with cisplatin and etoposide for postoperative multiple liver metastases. Although NEC is difficult to diagnose preoperatively, it should be considered an uncommon alternative diagnosis.
