The purpose of this study is to arrange the digital maps of Hamamatsu City and to construct the map information system to support the prediction and restoration of Tokai earthquake disasters. The authors arrange the land condition map and compute the populations of each land surface conditions and revealed that $37\%$ of the whole population lives in the safe land, but $63\%$ lives in the rather unsafe surface condition. The authors also arrange the digital map of the main lines of water supply pipe lines in corporation with the Hamamatsu City Water Supply Department and revealed the rather dangerous pipe line area in case of Tokai earthquake.

It is commonly believed that a gigantic earthquake (Tokai Earthquake) could occur in Shizuoka Prefecture in the near future. The Shizuoka Prefecture Government made the prediction report of Tokai Earthquake disaster damage. But this report does not pay attention to the ground conditions. The authors make a prediction map using GIS of Tokai Earthquake disaster damage in Asada-cho and Hirosawa Ni-chome in the central Hamamatsu City and revealed the location of dangerous houses and dangerous points in road networks in each town. These information could be useful when people try to find escape routes in an earthquake.

Japan's manufacturing is mostly dependent on the automotive industry in Toyota-Kariya cities. However, the nearby city of Hamamatsu is the home of a start-up ecosystem known as Japan's Silicon Valley. How is it possible to evaluate the innovative potential of each regional industry? What kind of guidelines exist for continuing R&D investment when companies' net incomes are negative in the face of the 'Valley-of-Death' or financial crisis? Is it possible to measure the regional resilience ability in the context of the financial crisis? Entrepreneurial innovation is defined as a real-option portfolio consisting of investment decision to commercialize R&D findings. The subcontractor system implies a vertical and tight industrial group. However, a start-up ecosystem means a platform for horizontal and flexible partnership. In this research, the data include the financial indices of each of 18 public companies in both regions between FY2009 and FY2017. The objective of this paper is to clarify the call option or resilience function of equity for R&D investment in the context of the financial crisis in both regions by using Bayesian MCMC analysis.

Metagonimus yokogawai (Katsurada, 1912) Katsurada, 1912 (Trematoda: Heterophyidae) is parasitic in the small intestine of mammals including man and birds in Far Eastern Russia, Korea, Japan, China, and Taiwan. In the present study, the metacercariae and adults of M. yokogawai were redescribed to designate a neotype of this fluke together with reviews of previous studies including study histories from the first discovery to now. We particularly, attempted to review the study histories and morphological descriptions of M. yokogawai for the species validity, and compared with the morphological characteristics and life cycles of the closely related species, Metagonimus takahashii and Metagonimus miyatai. Finally, we proposed a differential key for the 8 known Metagonimus species distributed in East Asia. Metacercariae were obtained from the body muscles of sweetfish (Plecoglossus altivelis) collected in the Asahi River at Takebe-cho, Kita-ku, Okayama City, Okayama Prefecture, Japan. Adults were recovered from the small intestine of Syrian golden hamsters, to which the metacercariae had been fed 14 days before. A neotype was selected out of the present adult specimens. The Asahi River at Takebo-cho became the type locality of M. yokogawai. In conclusion, the present review shows that M. yokogawai, M. takahashii, and M. miyatai are valid and discriminated by means of morphological characteristics.

사적 제280호 「서울 한국은행 본관」 정초석의 '정초(定礎)'글자가 조선통감부 초대통감이었던 이토 히로부미(伊藤博文)가 쓴 글씨라는 보도가 있었다. 서체 관련 전문가 3인으로 자문단을 구성하여 현지조사를 진행한 결과, 정초석에 새겨진 '정초(定礎)' 두 글자는 일본 하마마츠시(浜松市) 시립중앙도서관 소장자료상의 이토 히로부미의 필적과 운필법 등의 특징으로 그의 글씨임을 확인하였다고 보도되었다. 느낌에 의한 정성적인 판단 보다 객관적인 판단자료를 제공하려면 이미지분석을 통한 글자의 정량적인 비교를 통한 판단의 근거자료의 제시가 필요하다. 본고에서는 이미지분석 소프트웨어를 활용하여 이토 히로부미의 붓글씨와 정초석의 글자를 겹쳐 육안에 의한 비교와 글자의 면적을 측정하여 비교하였다. 이미지분석 소프트웨어를 활용한 글자 이미지의 비교분석과 소장자가 기술한 소장경위의 조사를 바탕으로 정초석의 글자가 보도자료의 내용대로 그의 글씨임을 확인하였다. 글자간의 유사성의 비교에 있어서 이미지분석법을 활용한 정량화를 통하여 객관적인 판단근거를 마련할 수 있음을 예시하였다.
