| 抄録 | With a population that is aging faster than any other in the world, Japan faces serious public finance problems, particularly when it comes to tax and social security issues. The structural reforms are urgently needed to accommodate the impending demographic change. We look at the Japanese tax and social security systems through a life−cycle general equilibrium simulation model. We aim to establish guidelines for fiscal reform in Japan’s graying society and use such advanced modeling techniques to permit the calculation of the effects of alternative tax policies on capital accumulation and economic welfare. We also examine the impact of progressive expenditure taxation, coming to the novel conclusion that this form of taxation may hold the key to overcoming the large welfare loss Japan faces as its society ages under the current tax system. Furthermore, we present the concrete measures of implementing progressive expenditure taxation. |

| 抄録 | This note considers a situation in which the publisher of an academic journal seeks to maintain the number of contributions to the journal by subsidizing the contributors with some incentive payments. We show that under the incentive payment scheme that distributes some pre−determined total amount of payments equally to each contributor (the constant total payment scheme), the number of contributions can fluctuate cyclically as well as chaotically over time when the potential contributors form adaptive expectations. Numerical simulations suggest, among other things, that the performance of the constant total payment scheme may be more efficient than the constant per−capita payment scheme when the total amount of payments is supposed to be small. |

| タイトル（別表記） | A view on incentive planning for R&D workers through a case study of the blue LED patent lawsuits in Japan |

| 抄録 | The purpose of this paper is to bring an institutional perspective onto the recent debates about incentive planning for R&D workers in Japan. This purpose is fulfilled through a case study of the recent civil trials in which an ex−employee as a plaintiff claimed any compensation for the corporate in−house inventions about blue light emitting diodes (LED). As long as technical achievements are to belong to an individual worker, the incentive planning which his or her employer may design will have to face two difficult tasks. Firstly, marginal analyses commonly applied in micro economics have certain utilities under the strict assumption of decreasing returns to productive inputs, but not applicable, in principle, to R&D activities. It is because such features as experiential learning and teamwork by technical professionals may increase returns to marginal inputs of technical labor. Secondly, negotiation transactions on the arms lengths basis are alternatively applied instead of the first, but incur many transaction costs between opportunistic players. Recent Japan seems oriented toward the second planning arrangement, but this paper suggests that the economic assessments of corporate in−house inventions should be complemented by peer reviews on the expectation that professional communities of technical experts share certain paradigms to tell us which inventions are more nascent and valuable and which are not. So far, it is said that these peer reviews have been submitted to courts after plaintiffs file complaints for compensations, but preliminary reviews at the time of patent applications may effectively decrease the probability of unexpected lawsuits and reprieve undue legal costs. |

| 抄録 | The link between changes in a subject's metabolic syndrome components and her estimated glomerular filtration rate (eGFR) was evaluated in healthy Japanese women. We used data for 53 Japanese women (46.0±10.9 years) with a 1-year follow up. eGFR was defined by a new equation developed for Japan. There were no significant relationships between eGFR and clinical parameters at baseline. Subjects were given advice for dietary and lifestyle improvement. At the 1-year follow up, eGFR was significantly increased. In addition, changes in eGFR were weakly correlated with systolic blood pressure(r＝－0.306, p＝0.0260). A decrease in systolic blood pressure may be associated with improving eGFR in Japanese women. |

| 抄録 | The transient systemic low perfusion that occurs during cardiovascular surgery leads to oxidative stress and the production of free radicals. A systemic increase of various markers of oxidative stress has been shown to occur during cardiopulmonary bypass (CPB). However, these markers have not been adequately evaluated because they seem to be reactive and short-lived. Here, oxidative stress was measured using the free radical analytical system (FRAS 4) assessing the derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP). Blood samples were taken from 21 patients undergoing elective cardiovascular surgery. CPB was used in 15 patients, and abdominal aortic aneurysm (AAA) surgery without CPB was performed in 6. Measurements of d-ROMs and BAP were taken before surgery, 1 day, 1 week, and 2 weeks after surgery, and oxidative stress was evaluated. The d-ROM level increased gradually after cardiovascular surgery up to 2 weeks. Over time, the d-ROM level after surgery involving CPB became higher than that after AAA surgery. This difference reached statistical significance at 1 week and lasted to 2 weeks. The prolongation of CPB was prone to elevate the d-ROM level whereas the duration of the aortic clamp in AAA surgery had no relation to the d-ROM level. The BAP was also elevated after surgery, and was positively correlated with the level of d-ROMs. In this study, patients who underwent cardiovascular surgery involving CPB had significant oxidative damage. The production of ROMs was shown to depend on the duration of CPB. Damage can be reduced if CPB is avoided. When CPB must be used, shortening the CPB time may be effective in reducing oxidative stress. |

| 抄録 | We studied the prevalence of hepatitis C virus infection among blood donors from 3 hospitals of Central Myanmar and 7 hospitals of Lower Myanmar in the Yangon area, and analyzed the factors associated with the infection. The study period was from November, 2005 to June, 2007. A pre-tested questionnaire was used to obtain information on age, ethnic group, marital status, tattooing, body piercing, history of receiving transfusions, and liver diseases in self and in sexual partners. Data on seropositivity to hepatitis C, hepatitis B and human immunodeficiency virus infections were recorded. A total of 65,240 blood donors participated in the study. Their ages ranged from 18 years to 60 years (mean±SD＝29.5±9.3). The male-to-female ratio was 6：1. The prevalence of the antibody to hepatitis C was found to be 0.95% with varying rates (0.34 to 2.03) among hospitals. Females had a slightly higher rate (1.06%) than males (0.93%) (p＝0.237). Multivariate analyses revealed the following factors to be related to HCV infection:HIV infection, odds ratio (OR)＝3.0 (p＝0.003);history of liver disease, OR＝8.9 (p＝0.001);and age 30 years and above, OR＝2.6 (p＝0.001). We discuss the varying prevalences of HCV around the world. |

| 抄録 | We evaluated the efficacy and toxicity of cisplatin/docetaxel (CDDP/TXT) chemotherapy and identified prognostic factors in Japanese patients with cancer of unknown primary site (CUP). Twenty-eight consecutive patients seen at a single institute were reviewed retrospectively. Sixteen patients were treated with TXT 80mg/m2, followed by CDDP 75mg/m2. The overall response rate to CDDP/TXT treatment was 62.5%, with a median survival time (MST) of 22.7 months. Common adverse reactions were myelosuppression and hyponatremia. The MST of all 28 patients with CUP was 8.3 months, and the 1-year overall survival rate was 45.6%. Univariate analysis identified 5 prognostic factors:performance status, liver involvement, bone involvement, pleural involvement, and lymph node involvement. In conclusion, CDDP/TXT chemotherapy is effective with tolerable toxicity in patients with CUP. Japanese patients with CUP might be chemosensitive and may survive longer. |

| 抄録 | Endothelial glycocalyx (GCX) has been reported as a protective factor for vascular endothelial cells (VEC) in diabetes and hypertension. However, the involvement of GCX impairment in ocular vasculopathy remains unclear. We evaluated the changes in the GCX thicknesses of the retinal and choroidal capillaries in rats with diabetes and hypertension by cationic colloidal iron staining using a transmission electron microscope. In the control group, the mean (standard error of the mean) thicknesses of retinal and choroidal GCX were 60.2 (1.5) nm and 84.3 (3.1) nm, respectively. The diabetic rats showed a significant decrease of GCX thickness in the retina, but not in the choroid, compared to controls (28.3 (0.3) nm, p＜0.01 and 77.8 (1.4) nm, respectively). In the hypertensive rats, both retinal and choroidal GCX were significantly decreased compared to the control values (10.9 (0.4) nm and 13.2 (1.0) nm, respectively, both p＜0.01). Moreover, we could visualize the adhesion of leukocytes and platelets on the luminal surface of VEC, at the site where the GCX was markedly degraded. These findings suggest that the GCX prevents adhesion of leukocytes and platelets to the VEC surface, and this impairment may lead to ocular vasculopathy in diabetes and hypertension. |
