| 抄録 | Filters are essential in the design of embankments/dams, drains and wells for water and oil supplies. As a result of these functions, filter use is increasing. In order to use the required filter, various empirical relations have been given based on mathematical and field experience. However, these guidelines have not worked to perfection considering the fact that clogging within the filter face is a serious challenge. A short review on filter design criteria is given in this script coupled with a numerical formulation to propose the design limits. |

| 抄録 | Echelon analysis (Myers et al., 1997) is a method to investigate the phase-structure of spatial data systematically and objectively. This method is also useful to prospect the areas of interest in regional monitoring of a surface variable. The spatial scan statistic (Kulldorff, 1997) is a method of detection and inference for the zones of significantly high or low rates based on the likelihood ratio. These zones are called hotspots. The purpose of this paper is to detect the hotspot area for spatial data using echelon. We perform echelon analysis for Korea earthquake data. We use ESRI’s ArcGIS that is geographical information system (GIS) software to make the meshed areas and get contiguity information of these areas. With this contiguity information on the meshed areas, we detect the hotspot area using echelon analysis and spatial scan statistics. In addition, we compare with the result of analysis based on the total of number of times simply and the seismic wave energy. |

| 抄録 | As construction of final waste disposal site is essential recently, a problem where we should build it becomes important issue. However, public opposition occurs for the construction because the final waste disposal site has negative image such as pollution of various kinds, increase of traffic volume and noise by truck and bulldozer, and aggravation of living conditions. Public opposition is the most critical problem in constructing final waste disposal site. The source of public opposition has been characterized as NIMBY or not-in-my-yard. This paper presents a survey of the resident awareness on final waste disposal site, and attempts to find factors which affect the public opposition using logistic regression analysis and CART(classification and regression tree). |

| 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 this paper, we built some models of the spatial data, and evaluate those, using the crime data of Kawaguchi city, Saitama prefecture in Japan. Compute the Moran’I statistics of five crime data related to thefts in the city, the value of sneakthief take the aggregation. So, we pay attention to the sneak, and make a model to estimate the incidence of the events. As a regression, we select the old-age index among regional indexes. Applying a simple regression(SR), a spatial autoregressive model(SAR), a geographically weighted regression(GWR) , we evaluate these models. In GWR model, it is interesting that there are some sections in which the sign of the coefficient takes the opposite versus SR and SAR models. So, stratifying the data by the sign of it, we investigate to data precisely. |

| 抄録 | It is necessary to consider a stochastic variability in modeling malaria epidemic behavior since the malaria infection cycle essentially depends on stochastic elements. For this requirement, we need to construct an appropriate statistical model from available data in advance. In this report, we provide some statistical models for the analysis of malaria epidemic behavior at Ishigaki Island. These models can be used for recurrence of past malaria epidemic and prediction of future malaria epidemic at Ishigaki Island. |

| 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 | This paper is an attempt to establish an objective criterion for civilizations, in order to treat them impartially and give them a fair assessment. First, theories up to the present about civilizations including those of Spengler and Toynbee are introduced. Second, the criterion presented by Bagby to distinguish major civilizations and peripheral civilizations are examined and proved to be subjective. Then the author proposes as an objective criterion for big civilizations just the pattern of succeeding four stages with the span of 400~500 years each. Big civilizations meeting this requirement which total eight or nine are divided into two types according to the difference of their nature. Lastly is shown how four puzzles of world history that have hitherto caused a lot of disputes (feudalism, absolute power of royalty, capitalism and modernization) can be solved through the recognition of these big civilizations. |

| 抄録 | Morphology and formation mechanism of poly (4'-oxy-4-biphenylcarbonyl) (POBP) crystals obtained by solution polymerization were firstly treated. It was concluded that the formation mechanism of the bundlelike aggregates of fibrillar crystals in POBP was fundamentally simillar to that in POB whiskers. Secondly the copolymerization effects of m-acetoxybenzoic acid and 4-(4-acetoxyphenyl) benzoic acid on the morphology of POB whiskers were studied. The experimental results strongly supported our proposal for the formation mechanism of whiskers which was consisted of crystallization of oligomers with a critical length as lamellae from solution and solid state polymerizationof oligomers between lamellae. Finally, the formation mechanism of poly (p-oxycinnamoyl) spherical products during solution polymerization was treated. The formation of these spherical products could be understood by overlapped phase diagram of melting depression curve and consolute curve of oligomers-solvent system. |

| 抄録 | The drop formation in immiscible liquid-liquid systems under mass transfer conditions was experimentally investigated. To know the exact effact effect of mass transfer on drop sizes, the decrease of interfacial tensions due to the presence of solutes has to be evaluate. Interfacial tensions of liquid pairs were measured with a Wilhelmy method as a function of the relative amounts at which both the solution and the solvent were mutually saturated. The interfacial tensions between the liquid pairs mutually saturated at on equal amount were found to be appropriate for the prediction of the drop formation accompanying mass transfer. |

| 抄録 | An alumina-zirconia (AZ) composite powder was prepared by thermal decomposition of the organic precursors, which were synthesized from ethyl acetoacetate aluminium diisopropylate and zirconium n-butoxide. Specific surface area of AZ was higher than that of alumina-zirconia (ALK) prepared from aluminium sec-butoxide and zirconium nbutoxide. True density of AZ was lower than that of ALK. Selective reduction of nitrogen oxide with propylene in oxygen-rich atmosphere on AZ was superior to that on ALK. |
