| Abstract | Transferrin (Tf) is thought to play a pivotal role in iron metabolism of various kinds of cells. Tf has specific receptors on the surface of the cells that require iron. Tf-receptor binding is followed by internalization through a system of coated pits and vesicles. The rapid decline of pH of these vesicles leads to the release and sequestration of iron by the cell. Apotransferrin-receptor complex returns to the cell surface, where under neutral pH conditions, apotransferrin is dissociated from the receptor. Recent advances in cellular and molecular biology, gene cloning and monoclonal antibody technique have elucidated many features of these processes at a molecular level. These advances are briefly reviewed, and particularly, our own observations concerning endothelial mediation of uptake of Tf by hepatocytes are discussed. |

| Abstract | In order to transfer quantum information, the use of spin chains has been proposed and their transfer characteristics have been analyzed. As one of the latter, the maximum of the transfer probability over sufficiently long time period is often considered important and some examples with high maximum values have been given. In these examples, the coupling between neighboring spins are tuned so as to attain high efficiency. In this article, we discuss the effect of noise on the values of coupling constant. As a result, we propose a system where the efficiency is high and also the effect of noise is small. |

| Abstract | In steel works, iron ores are stored in ore yard and sent to various plants of down stream accoding to transfer requests. To attain stable operation, it is neccesary to keep a certain allowable stock level in ore tanks of all plants. To this purpose, ore transfer routing method has been developed based on decentralized agent method. In case of disaster such as a big earthquake or a big fire, damages in the facilities of industrial complex may be unavoidable. In this paper, decentralized optimization method is tested to cope with such emergencies. Decentralized agents corresponding to kind of ore make their own transfer route plan exchanging information with others. As the application of the proposed method, transfer scheduling in ore yard in steel works are made in case of destruction of transfer facilities. |

| Abstract | In steel works, molten metals discharged from blast furnace are put into a pan for transportation called torpedo and transported to steel making factory by a locomotive. In molten metals transportation, it becomes issues to prevent temperature drop of molten metals for stable production of down stream plants to shorten transportation time. Therefore it is necessary to make an appropriate plan for molten metals transfer considering the production and the transportation simultaneously. In this paper, molten metals transfer planning method is proposed including production scheduling. That is, torpedo schedule, transfer request assignment and route plan of locomotives are optimized according to each objective. |

| Abstract | Trail Making Test（TMT）は，ワーキングメモリや反応抑制，反応の切り替えなどの能力が求められる神経心理学的検査である。TMT は実行機能評価法の一つとして広く用いられているが，子どもを対象とした標準値の作成や臨床応用に関する報告はいまだ少ない。そこで本研究では，TMT の小児期から青年期までの各年齢群別標準値を作成するとともに，各指標の発達的変化について検討した。その結果，Part A の遂行時間，Part B の遂行時間，B－A 値およびB/A 値の４指標において年齢による有意な発達的変化が認められ，本検査は子どもの実行機能の発達の程度を反映しうるものと考えられた。本法は従来のTMT よりも刺激数を削減し簡便化したものであり，注意欠陥／動性障害などの発達障害をともなう子 どもへの臨床応用が期待される。 |

| Abstract | At the early stage of this paper, Okayama prefecture was analyzed by the author focusing on the tendency of main sightseeing-areas based on the number of tourists for three decades (Ichiminami, 2002). In this study, the main sightseeing spots in Okayama pref. are also examined and the developments are explained in a more detailed and updated perspective by extending over current features and the number of tourists. One of the important reasons in a significant increase in tourists in Okayama is the opening of the highways, the bullet train and cross-linking of the Seto Ohashi Bridge. At the same time, there are some waves in the increase or decrease of the tourist trends appearing from several vital developments such as environmental, climatic, social, economic and spatial. In this regard, research objectives of the study are mainly based on investigating and making a comprehensive study on main sightseeing spots in Okayama pref. to find new tourism values and to provide a tourism inventory of Okayama pref. by means of information, data and clues from the field in/between the tourist destinations such as hotel guests, gardens and castles. Therefore, Okayama pref. has a rich potential of historical and cultural heritage in terms of spatial planning and growth. The important point is that the structural adaptation between historical and cultural assets and the city life should be provided and protected for domestic and foreign tourism as much as creating better futures in health tourism, gastronomy tourism, cultural tourism, belief tourism, congress tourism, thematic tourism and local tourism. |

| Abstract | The serum levels of total IgE, IgG and IgG(4) were compared among five age groups of patients with bronchial asthma. 1. The level of serum IgE was significantly higher in the patients before the age of 29 than in those between the ages of 30 and 49 (p < 0.02), between 50 and 59 (p < 0.01) and between 60 and 69 (p < 0.01). The serum IgE level tended to increase in the patients over age 70. 2. The serum level of total IgG was significantly higher in the patients over age 70 compared with the level in the 30-49 (p < 0.05) and the 60-69 year old groups (p < 0.05). 3. The serum IgG(4) level was increased with aging, although no significant difference was found among the five age groups. 4. The IgG(4) level correlated to a certain extent with the level of serum IgE. The results reveal that the levels of total IgE, IgG and IgG(4) are increased in the elderly patients over age 70, and that there is a relationship between serum levels of total IgE and IgG(4). |

| Abstract | We present an inversion method, called "column inversion", to retrieve two-dimensional variation of the depth to the Moho discontinuity from Bouguer gravity anomaly data, assuming that a density jump between the lower crust and upper mantle is regionally invariant. The inversion method is applied to reveal the apatial undulation of the Moho discontinuity in the Chugoku and Shikoku districts, southwest Japan. The result shows that the Moho is deep in the land area and shallow in the sea area. The Moho is anomalously deep in the west regions of Shikoku and Chugoku districts, where the prominent negative gravity anomaly is observed. The two-dimensional variation of the Moho depth is quite similar to that determined by inversion of the first P-arrival time data. The column inversion of the Bouguer gravity anomaly data is proved to be useful for determining the fine structure of the Moho discontinuity undulation. |

| Abstract | The use of dental implants has increased together with increases in the human life span and it has become an imperative subject for dentists to familiarize themselves with this treatment modality. Unfortunately, there has been no practical and quantitative method for in vivo evaluation of the stability of dental implants. In the tooth mobility examination, the tactile sense of natural teeth is different from that of dental implants. The authors have developed an automatic diagnosis system of tooth mobility for clinical use. The biomechanical mobility of peri-implantium is measured with a pseudo-random vibration, from which the viscoelasticity c1, c2, k of peri-implantium is obtained. The diagnosis system has been applied to the quantitative evaluation of the stability of implants : endodontics endosseous implants (titanium pin), endosseous implants (Bioceram). It has also been applied to the evaluation of the long-term prognoses of dental implantation (Bioceram) and the examination of Intramobile implant (IMZ), and the satisfactory results have been obtained. |

| Abstract | Glass-ceramics containing Pb(x)Cd(1-x)F(2) microcrystallites were prepared through heat treatment of Tm(3+)/Yb(3+)doped SiO(2)-Al(2)O(3)-PbF(2) glasses. The crystallite size was controlled by varying the heat-treatment time. By changing glass composition, two types of strong optical scattering, Rayleigh and Mie scattering modes were observed for the glass ceramics. In the case of Rayleigh scattering, the scattering region expanded to the long-wavelength side with increasing the heat-treatment time. On the other hand, in the case of Mie scattering, the region were hardly dependent on wavelength, and visible light was widely scattered. It was argued that the different scattering phenomena were caused by the different size of the crystallites or their morphogical texture. Furthermore, the glass-ceramics with strong optical scattering showed higher upconversion fluorescence intensity than the matrix glass. The mechanisms for the enhanced upconversion due to the scattering were discussed. |

| Abstract | The active sulfide chimney ore sampled from the flank of the active Tiger chimney in the Yonaguni Knoll IV hydrothermal system, South Okinawa Trough, consists of anhydrite, pyrite, shalerite, galena, chalcopyrite and bismuthinite. Electron microprobe analyses indicated that the chalcopyrite and bismuthinite contain up to 2.4 wt. % Sn and 1.7 wt. % Pt, respectively. The high Sn-bearing chalcopyrite and Pt-bearing bismuthinite are the first occurrence of such minerals on the submarine hydrothermal systems so far reported. The results confirm that the Sn enters the chalcopyrite as a solid solution towards stannite by the coupled substitution of Sn 4+ Fe 2+ for Fe 3+ Fe 3+ while Pt enters the bismuthinite structure as a solid solution during rapid growth. The homogenization temperature of the fluid inclusions in anhydrite (220-310℃) and metasured end-member temperature of the vent fluids (325℃) indicate that the minerals are precipitated as metastable phases at temperature around 300℃. The Sn-bearing chalcopyrite and Pt-bearing bismuthinite expess the original composition of the minerals deposited from a hydrothermal fluid with temperatures of about 300℃. |

| Abstract | Several methods to derive thermodynamic sum rules for a system including charged particle are proposed and applied to charged mixtures as well as one-component systems. The validity of the statements is examined carefully with respect to the ordering in the powers of the wave number. As for the mixture of electrons and ions, it is shown how the aspect of the one-component plasma or the ionic mixture appears when electrons become strongly degenerate. |

| Abstract | The balneotherapeutic tunnel of Radha usberg is located in Badgastein 1280 meter above the sea level and was instituted to offer a new and unique thermal therapy in 1954. The ther mal therapy is performed for a period of 8 months from February to October seasonally on patients of more than 35,000 from all over the world. The information given by chief Dr. Beate Sandri is summarized as follows; There are 3 cooperative acting factors such as the heat inside the tunnel of 37.5-41.5℃, high humidity and high content of Radon. They stimulate a pituitary - adrenocortical system enough to sedate the vicious circle of pain pathology and to improve a peripheral tissue perfusion. This balneotherapy is completed preferably in combination with massage and exercise, and is repeated in each season with patience. The indications are as follows; 1. chronic rheumatic arthritis, 2. degenerative arthrosis, 3. collagen diseases, 4. gout, 5. peripheral vascular diseases, 6. posttraumatic disorders, 7. central and peripheral nerve disorders, 8. allergic diseases, 9. hormonal and autonomic nerve disorders. Cure effect is evaluated by the improvement of subjective symptoms such as relief from pain, extension of the range of movement, increase of daily activities and so on, regardless of the pathology of each joint. The balneotherapy aims to stimulate patients' own abilities, so that the potential curability of the patients is set forth as a premise; so called end stage patients are beyond the remedy as Prof. Scheminzky insists. |
