| Title Alternative | The Student Exchange Programme between Okayama University and the University of Edinburgh : Receiving Overseas Students |
| FullText URL | oer_035_2_037_052.pdf |
| Author | Hirota, Yoko| Oka, Masumi| |
| Abstract | Hirota and Oka (2003) showed in great detail the process which led to the academic exchange between Okayama University’s Faculty of Economics and the University of Edinburgh’s Faculties of Arts and Social Sciences, and was concerned mainly in the procedure of sending students to the University of Edinburgh. This paper will focus on the procedure and the actual situation concerning the receiving of students from the University of Edinburgh. As the agreement stipulated that up to two exchange students were admitted to each institution per year, Okayama University received 15 students from the University of Edinburgh over a ten−year period. Concerning the student’s ability in acquiring a second language, it could be read as follows ; the students with an upper beginner or intermediate level of Japanese prior to joining the exchange programme, showed great improvement during their stay in Okayama and graduated from the University of Edinburgh, Japanese Studies course or Japanese Studies and Linguistics course with an honours degree. Thus, the programme could be said to have obtained a desirable result in regard not only to student numbers involved in the exchange programme but also to their academic performance. However as it was the first exchange programme that the Faculty of Economics had been engaged in, the teaching staffs involved were troubled by many unexpected problems in relation to the students from Edinburgh. For example, housing and the high cost of rent proved to be a serious problem. As the Faculty of Economics is about to embark upon a new exchange programme with Kangwon National University, the Republic of Korea, we believe that it would be in both the interests of the students and members of staff if we looked back to the exchange programme we had with the University of Edinburgh and attempted to learn from the valuable experiences we had. |

| Abstract | It’s time to think over the appropriateness for the present and the prospects of economics. That work should be full of sufferings. In this paper I’ll focus the coordinating power among the sections inside the firm. There are the two kinds of behavior between workers and employers, cooperative and hostile. These behaviors are implemented under the pressure of situations I called rivalry. They are utilized for deciding the level of transaction cost. The cost decides also the internal price and the section’s advantage issuing from its own suitable negotiation, basing on the size of R & D. The activity process of decision-making of an organization is indispensable for the analysis and the boundary of the various internal organization. The internal economic analysis covers the important theory and the empirical knowledge of some hierarchical relations between members inside the firm, that is, employer as a principal and worker as an agent. 'Inside Transactions of the Firm' looks like to be so attractive. The last section-the coordinating mechanism and rivalry-includes the great ideas. People try to do the best for themselves, when things turn out badly for the all. |

| Abstract | We consider a society which consists of two sectors, the educational sector and the production sector. We define the educational sector as one that produces two outputs jointly, higher education forming human capital and research increasing the stock of social knowledge. Social knowledge determines the level of technology in the production of consumption goods. Our purposes are to clarify the nature of higher education and to analyze efficient resource allocation in a two−sector economy, considering the external effects of education and research activities in the context of an endogenous growth model. |

| Title Alternative | Regional differences in medical expenses for the elderly and the economic implications |
| FullText URL | oer_036_2_015_034.pdf |
| Author | Chino, Tetsuro| Sugino, Makoto| |
| Abstract | The purpose of this paper is to clarify characteristics of regional differences in medical expenses for the elderly over the period 1983−1999 in Japan, and to propose a new hypothesis for explaining the differences from a viewpoint of property right theory. Under the Japanese healthcare delivery system, medical institutions coexist in spite of the various forms of their property rights, and provide a wide range of medical services. Throughout the period, regional differences in medical expenses per elderly person have been decreasing and still remained at the high level. With regard to inpatient medical expenses per elderly person, the maximum still exceed the twice of the minimum at the prefectural level. The empirical results show that private hospital institutions specialize in providing inpatient medical services for the elderly in the hospital sector, and the number of these hospitals is one of the major determinants for regional differences in inpatient medical expenses for the elderly. |

| Title Alternative | 35 HoursWork a Week in the French Automobile Industry |
| FullText URL | oer_037_4_013_035.pdf |
| Author | Shimizu, Koichi| |
| Abstract | The legal weekly working hours in France have been reduced to 35 hours from 2000 by the so called "Aubry’s law" of 1998. After the victory of conservatives in the legislative election in 2002, the conservative government is trying to moderate the regulation of overtime work, stipulated by the Aubry's laws of 1998 and of 2002, in order to make it a dead letter. However, the 35 hours work is not only supported by the public, but also positively accepted by big companies. In this paper, I show the real feature of 35 hours work at the company level, based on my interviews with French carmakers, Renault, Peugeot SA, and Toyota Motor Manufacturing France (TMMF), and on their unions−management agreement about the application of 35 hours law of 1998. The main results of this analysis are as follows. Firstly, the negotiations between unions and management for fixing their agreement were the occasion to revise their industrial relations, because the problem of working hours was the central issue influencing entire life of employees, and have served to stabilize their relations. Secondly, the carmakers positively evaluate the 35 hours law, because the law has allowed the flexibility of work organization, by which they can realize considerable economy of scale. Thirdly, they are receiving the government’s financial aide given to the companies, which have applied 35 hours régime and increased their employment. For these last two reasons, the carmakers are able to lower their unit labor cost in spite of the increase in the hourly wage. At the last analysis, they surely profit from the 35 hours law, and have no reason to object to it. |

| Abstract | 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. |

| Abstract | In many standard undergraduate textbooks of macroeconomics, open economies are discussed by means of the Mundell−Fleming model, an open macroeconomic version of the IS−LM model. This short paper develops a simple differential−equation version of the dynamic Mundell−Fleming model, taking account of two key assumptions : (i) the Marshall−Lerner condition is globally violated and (ii) the investment function depends nonlinearly on the current output level. Under our settings, we demonstrate that the exchange rate and the other relevant variables can display persistent fluctuations due to the occurrence of a stable limit cycle. We also discuss a paradox that the resulting dynamics may well be consistent with the J−curve effect. |

| Abstract | This paper considers a dynamic commons game in relation with mitigation of invasive alien species such as nutria in Okayama. In our commons game, players (trappers) non−cooperatively seek to maximize their own payoff by extracting the renewable resource stock (nutria). One key assumption is that the cost of extraction of the resource is negatively related to the current stock level. For a low level of resource stock, the extraction cost is high, which makes the extraction less lucrative for the players and which in turn stimulates the renewable resource stock to regenerate more rapidly. As the resource stock reaches a high level, the reverse process will start, and this can cause oscillating behaviors. Our simple model proposed here exemplifies that an increase in the number of players can drastically change the qualitative as well as quantitative features of the dynamics for the renewable resource stock. |

| Title Alternative | Market Risk and Private Risk −Financial Appraisal of Investment Projects− |
| FullText URL | oer_037_1_035_051.pdf |
| Author | Koyama, Yasuhiro| |
| Abstract | The purpose of this paper is to examine one of the functions which entrepreneurs may play in the course of industrial development through a case study of Japan’s RPG development race. As Japan’s toy manufacturers often said, their market was characteristic of its small size and considerable demand volatility in comparison to other consumer products. Entrepreneurs must have seen any commitment to a cutting edge product, video games, as only a gamble and therefore behaved in a trial−and−error way. Furthermore, judging from the fact that no one could imagine the video game would come to turn over ¥1500 billion in 20 years, the firm level trial−and−errors and their subsequent variety of strategies on the industry level must have been the key to understand the unexpected market growth and technical evolution. However, recent management thoughts told us that the strategic variety in an industry could be possibly indulged by various pressures towards homogeneity. Such counter powers are referred to as organizational isomorphism, strategic bandwagon effects and so on. To examine those pressures which drive entrepreneurs back and forth towards strategic variety, this paper looks at the structural characteristics which underlie the way entrepreneurs see things in an uncertain environment. The case analysis takes the view that the video game industry was so uncertain that nothing could affect so deterministically entrepreneurs’ behaviours other than their perceptions. As a conclusion here, this paper points out some tradeoffs underlying the two different strategies which the twin peaks of Japanese RPG producers, Square and Enix, employed to meet with the uncertainty of the infant RPG market. It also argues that these tradeoffs based on two different perceptions might have kept their startups from the isomorphic indulgence. As a more prospective argument, questioned is the quality of strategic variety which is often deemed as an unquestionable remedy to industrial stagnation. |

| Abstract | The study attempts to analyze the ins and outs of the risk reporting guidelines in UK. The guidelines advocate for the voluntary adoption of risk reporting through annual reports of the company. This voluntary reporting of risk will ensure the transparency and efficiency of the company management that eventually help the company to obtain funds from the capital market with the possible lowest cost. They also advise to disclose material / relevant risk information in a proper way so that the users can take their economic decision based on those disclosed information. On the other hand, company need not to disclose the commercially sensitive risk information, as it can give advantage to the rival companies. This risk reporting guidelines are also having some weaknesses. Such as, they mention about inverse relationship between level of disclosed risk information and cost of capital without any empirical evidence. Guidelines give a vague direction about the commercial sensitive risk information because companies can hide some important risk information on the ground of commercial sensitivity if needed. Other lacking include unavailability of suitable / reliable risk identification and measurement tools, expectation about common knowledge and so on. |

| Title Alternative | STUDIES OF THE RADIOACTIVE SPRINGS (XXXIII) EFFECT OF RADIOACTIVE THERMAL BATH ON POTASSIUM, CALCIUM, SODIUM, CHLORIDE AND PROTEIN LEVELS IN SERUM |
| FullText URL | pitsr_012_034_041.pdf |
| Author | Onda, Sakue| |
| Abstract | In order to study the effect of radioactive thermal bath on mineral substances in blood, the author bathed rabbits in Misasa Hot Spring (Yamada-Yu) once daily for 5 minutes dnring the successive 3 weeks, and determined potassium, calcium, sodium, chloride and protein levels in serum before and after the bath every week. The radon content of Yamada-Yu was 300-600×10(-10) curies per liter, its water temperature being 42-44°C. at that time. In the early stage of serial baths calcium decreased, and potassium, sodium, chloride and protein content increased. But in the later stage a reversed tendency was recognized. It was concluded that radioactive thermal baths of Misasa had no peculiar effect on mineral substances in rabbit's serum, compared with the effects of the other kinds of thermal baths |

| Title Alternative | EFFECT OF THE INTERNAL USE OF MISASA (RADON SPRING), HAMAMURA (SULFATED CALCIUM SPRING) AND TOTTORI (SULFATED MURIATED SPRING) SPRING WATERS UPON THE ALIMENTARY HYPERGLYCAEMIA IN RABBITS |
| FullText URL | pitsr_010_013_016.pdf |
| Author | Oshima, Yoshio| |
| Abstract | Five years ago Morinaga reported that the intemal use of the thermal waters of Misasa promoted the action of insuline, inhibited the adrenaline hyperglycaemia and suppressed the alimentary hyperglycaemia. But the highest radon content of the waters used at that time was about 1000×10(-10) Curie units per liter. Recently a more highly radioactive spring was found in Misasa, its radon content being 3000-4000×l0(-10) Curie units per liter, though very feebly mineralized (under 0.5 g per liter) and cold. Therefore the hypoglycaemic effect of this newly discovered water was, investigated in rabbits and compared with the effects of two other thermal waters in Tottori Prefecture and of plain water as a control. Twenty cc. of ten per cent glucofoe solution in thermal waters or in plain water per kilogram of bodyweight was administered to the rabitts by stomach tube and blood sugar level was determined before, 30, 60, 120, and 180 minutes after the administration. All of the three thermal waters decreased the glycaemia significantly as compared the results with plain water control. |

| Title Alternative | STUDIES ON SERUM MUCOPROTEIN (2) RELATION BETWEEN SERUM MUCOPROTEIN LEVEL AND DIFFERENTIAL AGGLUTINATION TEST FOR RHEUMATOID ARTHRITIS. AN EXPERIMENTAL AND CLINICAL STUDY |
| FullText URL | 013_024_030.pdf |
| Author | Ueda, Yoshio| |
| Abstract | (1) Mucoprotein level in serum and agglutination reaction by Rose for rheumatoid arthritis were measured in 40 cases of rheumatoid arthritis, cancer, pulmonary tuberculosis or liver disease (mostly acute hepatitis). A raised titer of mucoprotein was often observed in cancer, and a marked rise in agglutination titer was often proved in rheumatoid arthritis. But no significant correlation was proved between the serum mucoprotein level and agglutination test in patients. (2) [n animal experiment an inereased agglutination titer was caused by sensitization with egg albumin, Arthus' s phenomenon, anaphylactic, shock, thermal spring bath, X-ray irradiation, blocking of reticuloendothelial system, liver injuries, injection of A. C. T. H., adrenaline, atropin or pilocarpin. A simultaneoas rise in serum mucoprotein level was observed after sensitization, thermal bath, X-ray irradiation, administmtion of chloroform, injection of toxic agents to vegetative nerve system. And a significant positive linear correlation was proved between the serum mucoprotein level and agglutination titer in the animal experiment on the whole. But a dissociation in this relation was observed during anaphylactic shok. Namely serum mucoprotein level tended to fall soon after the reinjection, while the agglutination titer rose higher temporarily and then both showed a tendency to decrease. |

| Abstract | There are many experimental reports and clinical observations about the internal use of thermal waters on carbohydrate metabolism, and alkaline springs, alkaline common salt springs and sulphur springs are used for the balneological therapy of diabetic patients. The author reported that the internal use of the radon springs of Japan, such as Misasa, Ikeda and Masutomi thermal waters promoted the action of insuline and inhibited the experimental hyperglycemia in rabbits, and he suggested that these radioactive waters also would be able to utilize for the diabetic treatment. On the other hand, trace elements such as Cu, Zn and Mn have protective effects against disturbed carbohydrate metabolism of diabetic body. Some thermal waters contain these trace elements in various degrees, and Oshima & Ashizawa observed that after the drinking of Fujino mineral water the iron, copper, nickel and cobalt content in blood rose temporarily. In this report, the author investigated the influence of the drinking of Asozu (weak common salt spring), Hamamura (sulphated bitter spring), Kaike (calcium chloride containing saline spring) and Fujino (acid alum vitriol spring) Spring waters upon the alimentary hyperglycemia in rabbits. Thirty ml. of 10% glucose solution in thermal water (Fujino Water was diluted twice with plain water) or in plain water per kg. of bodyweight was administered to the rabbit by stomach tube and blood sugar level was determined before, 1/2, 1, 2, 3 and 4 hours after the administration. The results were as follows: 1. The drinking of Asozu Spring water inhibited the alimentary hyperglycemia compared with the plain water as a control. 2. Hamamura Spring had a tendency to decrease the blood sugar level. 3. Kaike Spring water had no inhibitory a.ction upon the alimentary hyperglycemia. 4. In spite of the existence of trace elements, Fujino mineral water had no significant effect. The author supposed that this was due to its high acidity. |

| Title Alternative | EFFECT OF WATER LEVEL OF RIVER ON MINERAL SPRING |
| FullText URL | pitsr_014_015_021.pdf |
| Author | Umemoto, Shunji| |
| Abstract | From June 1953 to January 1954, the water temperature and amount of flow of a spring called IITanaka-no-Yu", Misasa Hot Springs, Tottori Prefecture, were observed continuously. It issues 10 metres north of the riverside of the River Misasa and a stream runs 3 metres south of it. The water level of the River and the stream were also observed. The water level of the stream have close connection with the water volume of rice-field which surround that spring, because it is a watercourse of irrigation to rice-field. It was found that when the amount of flow increased, the water temperature rose, namely there was a positive correlation between them, and the correlation coefficient was 0.952 (highly significant). The analysis of variance showed that the amount of flow would be affected by the water level of the River but would not be severely affected by that of the stream. The correlation between the amount of flow and the water level of the River was also positive and the correlation coefficient was 0.731 (highly significant). As a result of the analysis of variance, the computation of confidence limit and the analysis of covariance, in summer the averages of the amount of flow and the water temperature would be higher than those in autumn and winter. This difference was seemed to be induced by the water level of the stream. The end of the observation, a dam had been constructed 20 metres down (west) the River and she rised, but the effect of it must be observed after this. |

| Abstract | The value of spa treatment of rheumatic disease is an established feature of medical management based on experiences for many centuries. The author has been practising the balneotherapy of rheumatic diseases at Misasa Spa for several years, and has found this therapy efficacious in many cases in relieving the anemia that accompanies rheumatoid arthritis. For this reason, the author is investigating the metabolism of iron in rheumatic anemia, which is expected to occur in the course of the spa treatment. In this report, the results of clinical examinations of 24 patients with rheumatoid arthritis, of the type (2. 2. 2.) Polyarthritis systemica chronica (in Prof. Kodama's classification of arthritis), are described. I. Some observations of anemia in rheumatoid arthritis 1. The peripheral blood The number of erythrocytes is 266×10(4)～455×10(4)/c. mm. (average: (381±32)×10(4)/c. mm.), Hb-content : 55～90% (average : 76±5.8%), and the color index is about 1.0. The anemia of rheumatic disease treated is mostly normochromic. The white blood count is between 3240 and 13300/c. mm. (average: 6421±955/c. mm. ), and the number of the leucocytes in 80% of the cases ranges within the normal limits. Eosinophilia is observed in 15% of the cases. 2. Anemia-producing substance in the serum of rheumatoid arthritis When serum from rheumatoid arthritis patients was injected into rabbits, the number of erythrocytes and the hemoglobin -content of the rabbits was found to decrease markedly for 2～6hours after the injection. But no such effect was observed when the serum of healthy subjects was injected. From this, the author presumes the presence of an anemia-producing substance in the serum of rheumatoid arthritis. The nature of this substance in now under investigation. II. Clinical-biochemical studies 3. Gastric acidity of rheumatic patients Of 7 cases examined, anacidity of gastric juice was observed in 2 cases, subacidity in other 2 cases and normacidity in the remaining 3 cases. Thus, a decrease in the gastric acidity was found to occur in 57% of the cases. 4. Takata-serum-test and sedimentation rate It is said that the sedimentation rate and the Weltmann-reaction are very sensitive indicators of the extent of the activity of rheumatic disease. The Takata-serum-test was applied in 18 cases and was found to give positive results in 10 cases (55%). The sedimentation rate was found to increase in 17 of 20 cases (85%). 5. Blood uric acid As is well known, the concentration of uric acid is abnormally high in the blood of patients with gout; while, according to the literature, the blood uric acid levels of patients with rheumatoid arthritis range within the normal limits. The author, using the method of Benedict, obtained the following results for blood uric acid in 14 normal subjects in fasting state: Range - 2.30～3.47mg./dl. , 5% rejection limit -- 1.97～3.68mg./dl. In 5 of 7 cases of rheumatoid arthritis, the blood uric acid levels were shown to be above the upper limit of the normal range, but the concentrations of blood uric acid of non-rheumatic joint diseases and neuralgias were mostly within the normal range. 6. Blood sugar The fasting blood sugar levels of rheumatoid patients ranged from 82 to 1l0mg./dl. (average : 100mg./dl.), higher than the levels of healthy subjects (78～108mg./dl., average : 90mg./dl.). The intravenously injected glucose load test was applied to 8 rheumatoid patients. A solution of 40 ml. of 20% glucose was injected into a fasting subject for 2 minutes. Blood samples were taken before the injection, 3 minutes after the injection, and at each subsequent 10 minute-interval for 70 minutes. The glucose tolerance curves in 5 of these cases were found to be out of the normal range. It is to be noticed that the average blood sugar for rheumatoid arthritis is similar to the curve for liver disease. 7. Serum alkaline phosphatase activity and serum phosphorus The method of Taussky-Shorr was used for the determination of the level of alkaline phosphatase activity and inorganic phosphate in the serum. The alkaline phosphatase activity of 11 normal individuals ranged from 1.4 to 6.4 Shinowara-Jones-Rheinhart units/dl. (5% rejection limit), while in 4 of 8 cases of rheumatoid arthritis, it was of abnormally high levels. The concentration of inorganic phosphate in the serum of 12 normal subjects ranged from 2.9 to 5.0mg. /dl. (5% rejection limit), while in 3 cases of rheumatoid patients, it showed higher levels than normal. 8. Total cholesterol in serum The total cholesterol in the serum of fasting normal individuals was measured by Bloor's method, and the concentration was found to range from 124 to 188mg./dl. (rejection limit of 5% level of significance), and the total cholesterol in the serum of rheumatoid arthritis to be abnormally high in concentration in 6 of 7 cases. The liver function was evaluated by the Takata-serum-test, the test of fasting blood sugar levels, the glucose load test, and the test of serum alkaline phosphatase activity; and from this the hepatic dysfunction was found to occur in rheumatoid arthritis patients in about 50% of the cases examined. Disturbances in the protein, fat, and carbohydrate metabolism were also found to occur. The above-mentioned findings indicate that rheumatoid arthritis is not only a disease of the joints, but also a general and systemic illness. Attention must accordingly be given to the general condition of the patient in the treatment of rheumatic disease. |
