Local governments in Japan are partially funded by the central government to implement public assistance for the needy in theirjurisdictions. This paper exploits the institutional interplay of the Japanese intergovernmental transfers to identify the effects of centralfunding on the locally implemented social programs. The institutional features also enable us to frame the effect in terms of the average treatment effect, possibly taking advantage of the sharp regression discontinuity design. Our results indicate that local governments on average respond to an increase in the central funding by protecting more of ther residents. This does not contradict to the traditional view of the Japanese government that more of central funding increases unnecessaryexpenditures for public assistance by local governments. However, such an increase does not have to be unnecessary. Given a low take-up rate in the country, our results rather indicate that central funding can be an effective policy instrument to protect more of the needy.
Research on the Amount of Empty Containers in Japanese Main Ports

Economic development is remarkable in Asia and progress of industrialization of NIES, ASEAN, and China in East Asia has increased the international physical distribution in this area. However, an imbalance of trade becomes severe in these areas. The imbalance is especially big in the Asia-North America route and the Japan-China route. The imbalance in the Asia -North America liner route is 5.04 million TEUS in 2002. The transportation ratio of loaded containers between China and Japan route is approximately 3:1 in 2000. In other words, it means that the transportation of loaded containers from China to Japan is 3, the transportation of loaded containers from Japan to China is I. The imbalance at a port is generally obtained by subtracting export loaded container cargo volume from import container cargo volume. However, the imbalance and the empty containers at the port are not always same. Then, in order to evaluate rationalization and efficiency of maritime container transportation, we introduce the amount of empty containers at a port as an evaluation index. However, the past data of the amount of handling empty containers have a lot of lacking portions. Then, it is necessary to estimate the past amount of empty containers in order to grasp the amount of empty containers historically. So, we construct the mode that estimates the amount of empty containers using the imbalance of main port statistics in Japan.
Molecular targeted therapies for microscopic polyangiitis and granulomatosis with polyangiitis

Clinical trials and observational studies have established cyclophosphamide (CY) or rituximab plus glucocorticoid (GC) as standard remission induction therapies in patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). However, because these regimens are associated with serious adverse drug reactions, the development of drugs with novel mechanisms of actions are needed. Progress in basic and clinical research has identified novel candidate targeting molecules, including B-cell activating factor (BAF), C5a receptor, and interleukin-6. The combination of rituximab and BAF blockade in patients with MPA and GPA is under investigation in an effort to strike a better benefit-risk balance. Phase II clinical trials of avacopan (CCX168), an orally administered C5a receptor antagonist, have suggested a reduction in the dosage of concomitant GC or the replacement of GC in patients with MPA and GPA. The results from a currently ongoing phase III trial are awaited. Anecdotal case reports and an open-label pilot study have indicated the effectiveness of tocilizumab in patients with MPA and GPA. A randomized clinical trial comparing tocilizumab and intravenous CY in combination with GC is currently in progress. Molecular targeted therapy is expected to transform the treatment strategy for MPA and GPA to allow GC-free or at least less GC-dependent forms of therapy.

This paper describes a Generalized Minimum Variance Control (GMVC) strategy for Time Varying System (TVS). GMVC is one of the predict control methods, which are effective to Time Delay system. In TVS, polynominals of the model are noncommutative. Then, the cost function cannot be optimized accurately because a noncommutative noise term remains. This paper applies the Direct Pseudocommutation Method to TVS in order to improve the noncommutativity. The proposed pseudocommutation method is durable in time shift of time varying multiplications even though this GMVC strategy holds its simple structure.

Masayoshi Doi,Kazutoshi Nagamoto,Tetsuya Takehira,Yasuchika Mori 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
The purpose of this study is the identification of delay time of a design method that makes a controller for a system with a delay time in the case of a Controllable Pitch Propeller(CPP). A velocity response of CPPhas delay time until reaching the setting CPP"s angle and due to propeller"s slip. Especially, this study verifies the ship"s propelling force against the CPP"s angle and detects delay time by analyzing the data of the propelling force.

Argon ion sputter etching of AISI type 420 stainless steels was carried out at a power of 250 W for 14.4 ks to form coneshaped protrusions with bottom diameters of 10–20 μm by using a radio-frequency magnetron sputter apparatus. The sputter etching was also applied to AISI type 316 stainless steel at 250 W for 10.8 ks, and fi ne column-shaped protrusions with diameters smaller than 500 nm were formed. In addition, plasma-nitriding was applied to the protrusions of type 420 steel using nitrogen gas of 0.53 Pa mixed with argon gas of 0.67 Pa at a power of 50 W for 1.8 ks. The gripping ability of protrusions was measured by friction tests for three types of fiber sheets. For a cotton cloth, the friction coefficients of the as-sputter-etched and plasma-nitrided type 420 steel specimens were 1.3 and 1.7 at a nominal compressive stress of 0.8 kPa, and that of the as-sputter-etched type 316 steel specimen was 1.0. These are much larger than 0.8 and 0.5 of the specimens polished with #100 emery paper and buff -polished with alumina powders. Also for microfiber and polyester fiber sheets, the specimen with protrusions showed a higher gripping ability than those of the mechanically polished specimens. The reason for the large gripping ability of protrusion specimens is due to piercing of the protrusions between and into weaving yarns.
