Our Research Realizes New Dreams for Hokkaido
Hokkaido Research Organization Our research realizes new dreams for Hokkaido. http://www.hro.or.jp/ Message from the President Yoshikatsu Tanaka The Hokkaido Research Organization (HRO), a local independent administrative agency, was established in April 2010 by integrating 22 prefectural research institutes in the fields of agriculture, fisheries, forestry, manufacturing, food, environment, geology and architecture. The HRO is now focused on the three fields of food, energy and communities under the second midterm plan, which began in 2015, and utilizes its accumulated technologies and expertise while demonstrating its collective strengths in various fields to promote research on fundamental technologies that enhance the basic value of the technologies owned by Hokkaido industries and the effectiveness of administrative policies. It also works toward the practical use of fundamental technologies, contributing to the improvement of residents' living standards and the promotion of local industries as a comprehensive research institute in Hokkaido. Meanwhile, changes in socioeconomic circumstances and revolutionary advancement in scientific technology, such as the depopulation and aging of the population in Hokkaido at a faster pace than the national averages, worsening resource/energy problems, rapid development in ICT including IoT and big data, and advancing globalization, have various effects on the Hokkaido economy and lives of Hokkaido residents. To timely and appropriately deal with such powerful trends and promote research and development for the future, we are preparing the third midterm plan, which will begin in FY 2020. While defining the future vision, we will further strive to conduct high-value research and development that are used for the lives of Hokkaido residents and industries. -

Effect of Sasa invasion on CO2, CH4 and N2O fluxes in Sphagnum dominated poor fen in Bibai, Hokkaido, Japan. - Phyton (Horn, Austria) 45(4):(319)-(326). In Hokkaido, the northern part of Japan, degradation of natural wetland is occurring due to invasion of Sasa vegetation associated with construction of drainages. We measured greenhouse gas (GHG) fluxes at the Sasa invaded wetland in Bibai, Hokkaido. GHG fluxes at Sphagnum-dominated site (Sp) and Sasa invasion site (Sa) were measured by using a closed chamber method (transparent acryl chamber which covering plants) from July to October 2002. GHG concentration profiles, air filled porosity, and gas diffusion coefficient (D/Do) of topsoil were also measured. Water table depth was not significantly different between the sites. Air-filled porosity was significantly lower in Sa than in Sp (p = 0.03). D/Do was also lower in Sa than in Sp. CH4 emissions (mg C m"2 hr'1) were significantly lower in Sa (2.4 ± 0.64) than in Sp (3.7 ± 0.48) (p = 0.03), al- though Sa showed a higher CH4 concentration gradient at ground surface than that of Sp. -

Design Input Ground Motion Based on Regional Seismisity
13th World Conference on Earthquake Engineering Vancouver, B.C., Canada August 1-6, 2004 Paper No. 850 DESING INPUT GROUND MOTION BASED ON REGIONAL SEISMISITY Takashi SATOH1, Kenji IKEDA2, Takakichi KANEKO3, Takaaki IKEDA4 and Shigeru MIWA5 SUMMARY In the seismically active Japanese archipelago, earthquakes are generated by plate subduction, movement at inland active faults, and other movement. Seismic activity in Japan varies by region, with earthquake type and impact also differing by region. When considering the safety and economy of structures, earthquake motion inputs for aseismic design need to be based on accurate estimates of the seismic activity of the region. This paper aims to establish design-based earthquake motion inputs for intra-slab earthquakes by focusing on Hokkaido, where two large-scale intra-slab earthquakes occurred in recent years, and by simulating intra-slab earthquakes and related earthquake motions. Using parameters such as earthquake magnitude, average stress drop, and number and area of asperities, the magnitude of earthquake motions and the characteristics of seismic spectra were analyzed using the stochastic Green's function method. It was found that earthquake motions are dependent on key parameters including location of source fault, rupture starting point, and average stress drop. It was also revealed that spectral types of intra-slab earthquakes more closely resemble those of inland events than those of interplate events that occur in subduction zones. INTRODUCTION The activities of plates in the Japanese archipelago are known to be complex. In the Pacific Ocean to the east of the Japanese archipelago, the Pacific plate and Philippine Sea plate subduct under the continental plate, causing frequent earthquakes along the plate boundary. -

Through 34 long-term censuses, we confirmed large fluctuations in the population sex ratio of the 35 aphid Prociphilus oriens and detected frequency-dependent selection acting on these 36 fluctuations. Fluctuations in the population sex ratio were partly attributable to climatic 37 factors during the growing season. -
