| 抄録 | In this paper, we deal with the Miocene Ukan Formation, sporadically distributed in Ukan-cho, Okayama prefecture, from a viewpoint of analysis of lithology and molluscan assemblages. The Ukan Formation is lithostratigraphically divided into the Suzuoka Conglomerate, Yamagata Muddy Sandstone, Shimoyokomi Sandstone and Conglomerate, Azechi Sandstone and Conglomerate, Tsuneyama Siltstone Members in ascending order. The following 6 molluscan assemblages are recognized. The lower four members and the last member is correlative to the Lower Sandstone and Upper Shale Formation of the Bihoku Group, respectively judging from lithology and fauna. The temporal chages of the above mentioned molluscan assemblages represents that gradual deeping of sea during the depositional period from the Suzuoka Conglomerate and Yamagata Muddy Sandstone Members to the Azechi Sandstone and Conglomerate Member via the Shimoyokomi Sandstone and Conglomerate Member, and abrupt deeping of sea seems to have happened between the Azechi Sandstone and Conglomerate Member and the Tsuneyame Siltstone Member. |

| 抄録 | The Miocene Katauta Group of the Syohoku-cho area is subdivides into 6 members ; The Uetsuki Conglomerate Member, Nara Sandy Mudstone Member, Tai Gravelly Sandstone Member, Takatori Conglomerate Member, Ayabe Mudstone Member and Maruyama Mutstone Member from bottom to top. The unconformity between Miocene deposits and basement rocks in this area was traced to obtain geometry of the Miocene basin. Contour maps of the bases of the Miocene Yoshino Formation and Takakura Formation indicate paleo-topography. The obtained topography demonstrates a valley, which flowed to north-west, and a few islands and bays. It indicates that these Miocene successuions were deposited in the topography which resemble to the present Seto Inland. |

| 抄録 | The "Kibi Plateau" forms a unique geomorphic province with the gently-sloping and stable continental feature. Gravel deposites called the "Mountain Gravels", are distributed sporadically in the Kibi Plateau, and have been considered Pliocene deposits. However, recent fission-track ages of the tuff beds intercalated in the deposits have indicated that the ago of deposits are Paleogen in the age. So far, fission-track ages (using zircon) of 61 to 65, 55, 37, 34 to 35 and 27 Ma are obtained. Remaining the belt-like distributions of the Paleogene gravelly valley-full deposits suggest that the Kibe Plateau has been keeping as a stable block, and repeated periods of incision followed by sedimentation of valley-fill deposits are occurred in the area during Paleogene period. |

| 抄録 | The buried peat deposit was foud in the sand beach on the Desaki coast (Tamano City, Okayama Prefecture), the northeastern coast of Seto Inland Sea. In this study, we performed sulfur and diatom analyses of the deposit. The results were used along with 14C dates and the eruption age (7300 cal BP) of Kikai-Akahoya tephra (K-Ab) to derive sedimentary environments of the deposit. K-Ah was detected just below the peat deposit. At the culmination of the Jomon transgression, the peat deposit had been formed in brackish environments of salt marsh for about 300 years. In order to reconstruct local paleovegetation, we analyzed pollen, wood and plant fossils in the deposit. The results show vegetational transition from a deciduous broadleaved forest mainly of Ouercus subgen. Lepidobalanus to Pinus forest. In spite of the Holocene thermal optimum, the vegetation dominated by Ouercus subgen. Cyclobanopsis was not recognized at the Desaki site, as has been shown in many other regions of regions of western Japan. Ouercus sect. Prinus was replaced by Ouercus sect. Aegilops as the dominant section of Ouercus subgen. Lepidobalanus, suggesting early establishment of traditional rural vegetation of 'Satoyama' in Japan. However, no evidence for human agency has been obtained from the mid-Holocene archaeological sites around the Desaki site. Thus it is more likely that this vegetational transition resulted from the succession caused by natural forces such as ecological disturbance and climatic and/or endemic situations rather than by cultural deforestation. |

| 抄録 | Postglacial relative sea-level change of the Okayama Plain Area has been analyzed. Former sea-levels were recognized by using peat beds and marine organisms which are also available for 14C dating. Peat beds were rhought to be formed under a stable sea-level condition. 14C ages of the analyzed peat beds were seprated by 4 groups ; 30～18 ka BP, 11～8 ka BP, 6～4 ka BP and 3～2.5 ka BP, indicate 4 stable sea-level periods. 2 transgressive events (18～11 ka BP and 8～6 ka BP) and one regressive event (3.5?～3 ka BP) were also inferred. |

| 抄録 | In the Eastern Equatorial Pacific Ocean, increase rates of fCO2 in the air and the ocean were evaluated using the CDIAC data set. The fCO2 in the air was increasing about 1.28μatm/year during 1957-1995. This result is almost same as the rate at the Mauna Loa, Hawaii in Tropical Pacific Ocean. The increase rate of fCO2 in the seawater was estimated as 1.64μatm/year. In this study it is found that the increase rate of fCO2 in the seawater is the almost same as that of fCO2 in the air. This reault supports the result on the snapshot analysis of Takahashi et al. (1983) in thr North Atlantic Ocean during 1958-1982. It is smaller than the result including seasonal variation in the Eastern Subtropical Pacific Ocean. These reault indicated that the anthropogenic CO2 in the air has affected fCO2 in seawater through CO2 gas exchange between the atmosphere and the ocean. It is found that fCO2 in the seawater has increased in the Eastern Equatiorial Pacific Ocean in spite of the large CO2 source region. It suggested that CO2 source potential has not changed in this ocean durung 1957-1995. |

| 抄録 | The study srea, Mizushima is occupied by polder and reclaimed land. The ground of this area is composed of the Holocene deposits below the surface. The deposits are mostly 10 to 20m in thickness and composed of 2 units, the B Unit and C&D Unit. The B Unit is composed of muddy sand with 2 to 3m in thickness. This unit is thought to be deposited in the mouth of paleoriver. The C&D Unit is composed of marine mud and sand with 10 to 15m in thickness. This unit is especially soft and will expand ground oscillations during an earthquake. |

| 抄録 | With regards to the origin and evolution of the Pleistocene tracts (Lalmai, Madhupur and Barind tracts) of Bangladesh, two trends of thoughts are common. Most of the authors believed that the Madhupur, Barind and Lalmai tracts represent tectonically uplifted surface. Some researchers have different opinion and they believed that the Lalmai hills and the Madhupur locality represent tectonically uplifted blocks but the whole Barind tract and the major portion of the Madhuput tracts are not tectonically uplifted, rather these are originated by erossional-depositional processes. In order to solve the problems associated with origin and evolution of Pleistocene tracts of Bangladesh, further study is needed. Borehole data may be collected and fusion images can be prepared from aerial photographs and setellite images to detect netectonic imprins and geomorphological signatures of the areas. Elaborate laboratory analysis of sediment deposits, radiocarbon dating my indicate a new dimension about the origin and evolution of these tracts. |

| 抄録 | In 2004, Seto Inland Sea coast suffered severe damages of storm surge. This area never experienced storm surge damage in recent half century and people were not ready for the storm surge. In two typhoons of T0416 and T0418, surge anomaly were more than 150cm in Bisan-Seto area. Storm surges appeared after the maximum approach of typhoon not only due to surface low pressure but also due to wind stress as westerly. Because of geographical complexity of Seto Inland Sea, the surge process have not been well understood. Therefore, it is necessary to study the effects of the wind and the surface pressure using a numerical model. Atmospheric model MM5 and ocean model POM were used as a numerical experiment, including the astronomical tide model NAO. Aｓ the results of numerical simulation of the storm surge, atmospheric conditions were well simulated but ocean model was rather complex. There are a lot of island in Seto Inland Sea and sea water movement in the model was very much influenced by the topography and wind stress effect appeared much smaller. In the no-island model, storm surge height was a little improved. However the simulated surge height was still less than the observed height. Further improvement of the ocean model application should be considered in future studies. |

| 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 | 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. |

| 抄録 | Zinc oxide films were prepared on silica glass substrates by the use of an r.f. activated reactive evaporation (ARE) method, and were examined by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrical conductivity of the films and the doping effect of Al ions were also investigated. XRD measurements indicate that the films were c-axis oriented and that an r.f. plasma of Zn and O was necessary for the ZnO film deposition. Substrate temperature, oxygen gas pressure, evaporation rate, r.f. power and Al doping amount affect the c-axis orientation, the growth rate, the microstructure of the films and electrical conductivity. Optimum conditions with a fine texture of the surface and having good ctystallinity as well as good conductivity (≒10(-4)Ω・cm) were as follows : the substrate temperature; 200℃, the total evaporation rate; 1.0Å/s, the oxygen pressure; 2.0×10(-4) Torr, the r.f. power; 250W and the Al evaporation rare ratio; 2～6%. The films with 1.0×10(-3)Ω・cm were prepared at 50℃ for the substrate temperature. |
