| 抄録 | We carried out simulations of various scenarios for bioterrorist attacks using smallpox occurring in a virtual area set up on the basis of the census of Okayama-city, Japan, which predict the effect of control strategies against bioterrorism and the loss scale. On simulating a smallpox epidemic, we followed the method of the Individual Based Model stochastically, which can treat the population in the virtual area as individuals. Individuals have personal information, behavior patterns, and interactions among social groups. We took into consideration the influence of residual immunity due to past vaccination. We considered Traced Vaccination (TV) and Mass Vaccination (MV) strategies against bioterrorism. We investigated the effect of TV and MV strategies on the suppression of smallpox epidemics. Consequently, the TV strategy was found to have higher effectiveness than the MV strategy. |

| 抄録 | In an effort to secure the comfort of all aspect of life and security through electricity production, research, nuclear weapons production and medical uses, radioactive waste is being generated throughout the world as a result. Without pro – active management and protection, the hazardous nature of radioactive materials can pose serious threats to human health and the environment. A waste containment or disposal facility is required to isolate the waste from man and the biosphere to avoid any undue radiation exposure. Deep geological repository or disposal facility is considered as an effective way to isolate high level radioactive waste, HLW from the human environment, for which a multi – barrier system plays a very significant role. In this paper, literature collection was carried out, aimed to overview the present knowledge about the concepts of repository for HLW and to identify technologies that are currently available in the nuclear industry worldwide and the current state of barrier technologies for hazardous waste sites. |

| 抄録 | The current state of English as a Lingua Franca (ELF) used in communication between nonnative speakers of English seems to require a change in the way English is taught and learned. However, English has still been taught and learned as a foreign language as ifit were mainly used in communication with its NSs. This article attempts to review some ofthe recent advances in ELF research and then to draw their pedagogical implications. |

| 抄録 | It is significant to thoroughly scrutinize past practices and feats, to identify important factors towards developmental failure and success and to avoid mistakes for the future of an industrialized and prosperous Afghanistan. As a result of profound research, a number of researchers have added to the literature on the country’s history, culture, wars, strategic importance and position as a buffer state that cover Afghan polity, ideological dimensions, and social and cultural intricacies. However, few scholarly works exist on the political economy in general and on the historical economic performances and policies in detail. Drawing upon immense and varied literature, the purpose of this paper is to analyze and describe historical and social changes, economic structures and strategies of Afghanistan with a detailed account of (i) political vision, (ii) institutional reforms, (iii) economic agendas, and (iv) development progress in the light of economic development theory and practice. We conclude that being provided right policies and firm political determination, Afghanistan has the potential to become a more developed country in the short span of time. |

| 抄録 | Using a Gibbs distribution developed in the theory of statistical physics and a long−range percolation theory, we present a new model of a stock price process for explaining the fat tail in the distribution of stock returns. We consider two types of traders, Group A and Group B : Group A traders analyze the past data on the stock market to determine their present trading positions. The way to determine their trading positions is not deterministic but obeys a Gibbs distribution with interactions between the past data and the present trading positions. On the other hand, Group B traders follow the advice reached through the long−range percolation system from the investment adviser. As the resulting stock price process, we derive a Lévy process. |

| 抄録 | 神経生物学的研究における基本的分析系の確立を目的として、シクロデキストリン（CD）を用いたラット大脳皮質神経細胞の初代培養を試みた。β-およびγ-CDは、無血清培地（ダルベッコ改変MEM/ハム培地）中で胎生16および18日目ラットの神経細胞を11日以上10％胎児ウシ血清を加えた培地中と同じ程度に生存させたが、α-CDには生存維持効果が無かった。β-CDはγ-CDより安定した生存維持効果を示したが、胎生21日目ラットの神経細胞を用いた場合は有意に生存率が低下し、新生児ラットでは生存維持効果が無かった。β-CDを用いた無血清培養では10％血清培地中と比べて神経突起の伸展が悪かったが、ときに顕著な突起伸展がみられ、これはCD分子に取り込まれた生理活性物質の作用と考えられた。また、β-CDを用いた無血清培養を利用してラット脳から精製したコンドロイチン硫酸プロテオグリカン（CSPG）の作用を検討し、CSPGがグルタミン酸による神経細胞死を防止すること、弱いながら培養神経細胞の生存を維持する作用をもつことを示した。以上の結果から、この無血清培養法は神経生物学的研究において有用な分析系となりうることを指摘した。 |

| 抄録 | Reactions of cyclic ketones such as α-tetralone, 1,3-cyclohexanedione, or naphthalenedione with formamide or trisformylaminomethane (TFAM) have shown to form polyclic fused pyrimidines by us. Reactions of terpene ketones like l-menthone, d-camphor, l-carvone with TFAM were performed, and 8-isopropyl-5-methyl-5,6,7,8-tetrahydroquinazoline, borno[2,3-d] pyrimidine, and 5-isopropenyl-8-methyl-5,6-dihydroquinazoline were expectedly obtained from three terpenes. Minor products of 5-isopropenyl-8-methyl-5,6,7,8-tetrahydroquinazoline and 5-isopropenyl-8-methylquinazoline were formed with 5-isopropenyl-8-methyl-5,6-dihydroquinazoline by disproportionation reaction of l-carvone. Furthermore, No-formylmenthylamine, N-formylbornylamine, and N-formylcarvylamine were obtained as the Leuckart-type products terpene ketones in these reactions. The reaction of N-benzyl-4-piperidone with TFAM gave desired 6-benzyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. The reaction of diethyl succinylsuccinate with TFAM afforded tricyclic 4,9-dioxo-3,4,8,9-tetrahydropyrimido[4,5-g]quinazoline. Above compounds were determined by the measurements of their instrumental analyses. |

| 抄録 | Using paraffin-embedded tissue sections of liver cancer obtained from autopsy which had been preserved in 10% buffered formalin solution for 6 months while PCNA immunoreactivity was lost, we examined the effects of heat processing by either microwave(MW) and autoclave(AC) in the presence of various processing solution. It appeared that AC processing took shorter time period than MW irradiation to restore equal immunoreactivity. With regard to immunoreactivity retrieval by MW irradiation,however, variation of the degree of retrieval depending on processing time was smaller than in AC, and so the stable consequences were obtained. Although AC processed tissues tended to be stained deep, prolonged processing time presented strong background staining and blurred nuclear margins which made it difficult to estimate the positive cell count. As for the effects of processing solution, there was little difference in retrieval of PCNA among 0.01 M citrate buffer (pH 6.0), saturated solution of lead thiocyanate and distilled water, but the least background staining was observed with distilled water. These observations suggest that MW irradiation of which effect of retrieval is less dependent of processing time and with the least background stainability, is superior to AC processing for PCNA immunoreactivity retrieval on formalin-fixed tissues. |

| 抄録 | Optimal conditions for expressing a specific region of core protein of phosphacan, a chondroitin sulfate proteoglycan known as receptor type protein tyrosine phosphatase, as fusion protein with glutathione S-transferase (GST) in E.coli were examined. DNA fragments inserted into the expression vector (pGEX-4T-1) were amplified by RT-PCR using mRNA purified from E18 rat brain as template. Primers attached with BamH I or EcoR I restriction site on 5' end were used to amplify first strand cDNA by PCR. Before ligation into the pGEX-4T-1 for GST fusion protein, PCR products were once cloned using T-A cloning system because they were not directly ligated into the pGEX-4T-1. E.coli strain BL21 was transformed by pGEX-4T-1 ligated with restriction DNA fragment cut out from pCR II plasmid vector of T-A clonig system. The growth of transformed BL21 was not different between the colony incubated at 37℃ for 24-48h and the colony stored at 4℃ for 7-10 days after 24h incubation at 37℃. The desirable OD(550) of culture medium for inducing the expression of fusion protein by isopropylthio-β-D-galactoside (IPTG) was from 0.6 to 1.0, because expression of native E.coli proteins per ml of culture medium was increased relatively when IPTG was added at OD(550) more than 1.0. The expression of fusion protein reached plateau around 6h after the induction. Relative expression of native E.coli proteins per ml of culture medium increased thereafter. Therefore, it may be desirable to purify the fusion protein around 6h after the induction. |

| 抄録 | The true cercaria of Paragonimus mexicanus is the cercaria reported by Malek et al. in 1985 as a cercaria of P. peruvianus. However, there is a question whether the flame cell formula of 2〔(3+3+3+3+3)+(3+3+3+3+3)〕=60 is justified. Therefore, I question the possibility of the cercaria of P. mexicanus reported by Ito et al. in 1985. If it has a pseudo-sucker, it belongs to another species of Paragonimus cercaria. The cercaria reported by Tongu et al. in 1990 from Venezuela was eliminated the possibility of a new species. It is probable that this cercaria belongs to P. mexicanus. Ibanez revived the name of P. peruvianus in 1990 by the differences in the cercaria and adults. However, I disagree with his opinion. |

| 抄録 | A modelling of interface construction relating to power-line interference phenomenon was described. Source of interference was displacement currents which flowed from AC power-line configuration (APC) to a model. The interference depends on some factors: distance between the APC and a model ; length of unshielded leads ; position of the APC in vertical or horizontal direction ; and skin-electrode impedances which were balance or unbalanced. The position of APC and skin-electrode impedances were important in contributing of the interference. The interference was still large even though skin-electrode impedances were balance. This was caused by the disagreement in two displacement currents. It was overcame by adjustment of APC in vertical direction. As a result, total interference would be very small or zero. The result shows that interference in ECG signal recording can be eliminated to about 10 μV. Although interference of power-lines is a complicated phenomenon, the problem is easier to understand by using this modelling. |

| 抄録 | The purpose of this study is to analyze the structural relationship among the components of quality of life of kidney transplant recipients by using a causal model. The subjects were 329 recipients who had regular checks-up following transplantation in seven general hospitals in Tokyo, Gunma, Aichi, Okayama, and Hiroshima, and agreed to participate in this study. Ferrans and Powers's Quality of Life - Index Kidney Transplant version was used to measure perceived quality of life. The self-administered questionnaires were handed over to the subjects, who completed the instrument on the spot. After that, the answers were collected immediately. The factor analysis and the covariance structure analysis were used to make clear the structural relationship among the components of quality of life. The results of data analysis were as follows : (1) Five components of quality of life were extracted ; socio-economic functioning, family ties, emotional support, physical health, and peace & happiness. (2) The scores in the family ties dimension and the physical health dimension were higher than in the others, and the score in the socio-economic functioning dimension was the lowest. (3) The physical health showed the starting point in a causal model. (4) The physical health influenced the family ties and the socio-economic functioning. (5) The socio-economic functioning strongly influenced the peace & happiness and the emotional support. (6) The family ties influenced the socio-economic functioning, the emotional support, and the peace & happiness. Therefore, it was conceivable that it was particularly important to make approaches for the physical health, the family ties, and the socio-economic functioning dimensions to improve quality of life. |

| 抄録 | The average glandular dose to glandular tissue m mammography is generally assumed to be a function of beam quality (HVL), x-ray tube target material, tube voltage, breast thickness, breast composition and, to a lesser extent, x-ray tube voltage waveform. The average glandular dose is generally determined from published tables with knowledge of the above function. Tables for a high frequency x-ray generator are not yet published. In our study, the lookup tables for the average glandular dose were made at 28 kV (high frequency x-ray generator), employing a breast simulating tissue (0-100% adipose tissue, 0-100% glandular tissue) phantom for an Mo target - Mo filter source assembly. We tried to estimate breast composition from x-ray mammograms by digital image processing techniques, also using the simulating tissue phantom. Then the system that automatically calculates the average glandular dose from digitized clinical x-ray mammograms was built. It is considered that this system can contribute to objective evaluation of the average glandular dose. |

| 抄録 | Evaluation of dental implantation is very important because it gives useful information for both planning the dental treatment and evaluating of prognosis. This study aimed at improving our previously developed Tooth Mobility (TM) tester and developing a dental implant movement (IM) checker. The measuring probe included a bimorph transducer of two piezoelectric elements. It was actuated by single frequency and detected tooth acceleration. The acceleration signal was processed and the IM score was calculated in PC. Two artificial implant models in which IMZ implant was buried with different elasticity of surrounding (molteno(@)) were used to examine the performance of the IM checker. The IM scores obtained in the models were 29 and 58. The measurement time was below 15 seconds. The average of measurement variation of one operator was below 6% and the average variation among five operators was below also 6%. The IM checker reduced a measurement variation by 51% and a measuring time by 61% compared with those of the TM tester in natural teeth. The newly developed IM checker had sufficient measuring reliability and we could objectively estimate the implant movement in dental clinics. |
