　2015年10月に被用者年金制度は一元化される。共済年金は厚生年金に統一する。本稿では、まず、被用者年金制度一元化の改正の趣旨と概要について整理した。次いで、共済年金と厚生年金の制度的な差異を具体的事例を挙げながら明らかにした。あわせて、今回の一元化における制度的な差異の解消方法について、①厚生年金に揃える形での制度的差異の解消、②共済年金に揃える形での制度的差異の解消、③時間的経過を俟つ制度的差異の解消―の３つの視点で整理し直した。最後に、受給資格要件を判定するうえで、共済年金の加入期間と厚生年金の加入期間を合算して判断するものと、合算しないで判断するものがあることを明らかにし、長期加入者の特例については、受給資格要件を合算しないで判定するが、その妥当性を検討した。The Employees’Pension Schemes will be unified in October,2015.　Mutual Aid Pension will be unified into the Employees’Pension system for corporate workers.　Mutual Aid Pension is now divided into three systems ; Mutual Aid Association for National Government Employees, Mutual Aid Association for Local Government Employees, and Private School Mutual Aid System. But they will be unified into the Employees’Pension Insurance for company workers.　In this text, first of all, the purpose and the outline on the Unification of the Employees’Pension are arranged. Next, the system difference and the unification between the Mutual Aid Pension and the Employees’Pension system are clarified while showing some concrete cases. There are three methods for the unification of the system content. One is a method of putting the system content of the Mutual Aid Pension together on the Employees’Pension system. This is a principle. However, there are some items to put the system content of the Employees’Pension system together on the Mutual Aid Pension, too. And, the third is a transitional measure, leaving the system content just as it is for the time being. It is the method that the system content is standardized when a period of time passes.　Finally, I will point out that one eligible qualification for pension benefits is combined the periods of enrollment in Employees’Pension system with the periods of enrollment in the Mutual Aid Pension, but other eligible qualification is not combined. I will think that the benefits for 44 years or more enrollment in Employees’Pension should be combined the periods of enrollment in Employees’Pension system with the periods of enrollment in the Mutual Aid Pension

Role of histamine H3 receptor in glucagon-secreting αTC1.6 cells

AbstractPancreatic α-cells secrete glucagon to maintain energy homeostasis. Although histamine has an important role in energy homeostasis, the expression and function of histamine receptors in pancreatic α-cells remains unknown. We found that the histamine H3 receptor (H3R) was expressed in mouse pancreatic α-cells and αTC1.6 cells, a mouse pancreatic α-cell line. H3R inhibited glucagon secretion from αTC1.6 cells by inhibiting an increase in intracellular Ca2+ concentration. We also found that immepip, a selective H3R agonist, decreased serum glucagon concentration in rats. These results suggest that H3R modulates glucagon secretion from pancreatic α-cells

Material properties of a low contraction and resistivity silicon-aluminum composite for cryogenic detectors

We report on the cryogenic properties of a low-contraction silicon-aluminum composite, namely Japan Fine Ceramics SA001, to use as a packaging structure for cryogenic silicon devices. SA001 is a silicon--aluminum composite material (75% silicon by volume) and has a low thermal expansion coefficient ($\sim$1/3 that of aluminum). The superconducting transition temperature of SA001 is measured to be 1.18 K, which is in agreement with that of pure aluminum, and is thus available as a superconducting magnetic shield material. The residual resistivity of SA001 is 0.065 $\mathrm{\mu \Omega m}$, which is considerably lower than an equivalent silicon--aluminum composite material. The measured thermal contraction of SA001 immersed in liquid nitrogen is $\frac{L_{293\mathrm{K}}-L_{77\mathrm{K}}}{L_{293\mathrm{K}}}=0.12$%, which is consistent with the expected rate obtained from the volume-weighted mean of the contractions of silicon and aluminum. The machinability of SA001 is also confirmed with a demonstrated fabrication of a conical feedhorn array, with a wall thickness of 100 $\mathrm{\mu m}$. These properties are suitable for packaging applications for large-format superconducting detector devices.Comment: 8 pages, 4 figures, 1 table, accepted for the Journal of Low Temperature Physics for the LTD19 special issu
