Analysis of residential choice behavior at community scale

The complex problems shared by many cities throughout Japan are evidence of the impacts of land use plans that have been poorly designed and managed. Most of the existing plans in Japan have focused on the metropolitan areas but nowadays the physical layout or land use of communities is fundamental to sustainability. Community sustainability requires a transition from poorly-managed large-scale plans to land use planning practices at the community scale that maintain efficient infrastructures, and ensure close-knit neighborhoods and a sense of community. This paper provides a scheme for discussing the residential choice of people at the community scale in a local city in Japan in order to help local communities or local authorities concerned with suitable land use planning. First, this paper gives the key principles of residential choice behavior through the statistical analysis of the revealed preference of people who actually made the decision to choose the location of their new residence. Some interesting results are a bigger correlation than expected between the location of residence and the place of work, and a strong attachment of movers to their old communities. The latter half of this paper describes a modeling process for specifying the residential choice at the community scale. The discrete choice model adopted in the present study is a conventional disaggregate logit model that is capable of representing complicated individual choice behavior while they are changing their place of residence.

Spatial structure and prediction of Land use change considering development projects in urban promotion districts

n this paper, the actual conditions and the change structure of land use by using mesh data are studied in urban promotion area in a local hub city of Fukuoka, Japan. Firstly, all meshes are classified into 15 patterns based on distribution of land use. Then, transition probability models are made out based on the change of these 15 patterns. The Change structure of land use in an area depends on whether development projects are carried out or not. Therefore, all of the meshes are divided into two groups, and different transition probability models are proposed. Finally, a prediction method of land use is proposed under the consideration of the changing structure of meshes. Though our proposed approach is a macroscopic forecasting method of land use, it is useful to evaluate the effects of urban policies for development projects.

Evaluation of City Planning Road Development Measures by Microscopic Traffic Simulation

This study was made on the development plan of Kawahara Avenue, a road project authorized in city planning of Miyazaki City in Japan. The Kawahara Avenue development is planned along the Oyodo River. The land use of the area along the route comprises the tourist hotel zone, residential zone, and industrial zone. The Kawahara Avenue planning, unlike most other road development plans in Japan, requires much more than simply providing for the smooth flow of traffic. In the tourist hotel zone where the leading Miyazaki City hotels are located, the image and impression the tourists may have about the city is an important consideration. Therefore, the city government intends that this section of the road should not have excessive traffic. In the residential zone, the existing road network consists of narrow streets with no sidewalks. In addition to the sidewalks to be built, Kawahara Avenue is expected to handle a great deal of the traffic passing the residential district. This should help meet the goal in providing a safe environment for the pedestrians in other narrow streets without sidewalks. Under the circumstances as stated above, the planning has faced significant constraints in land purchasing involving forced move-out in the result of financial problems and coordination of the views between the city administration and the residents in the vicinity. The purpose of this research is to study under the given constraints what would be the most appropriate plan for the development of Kawahara Avenue. First, a traffic monitoring survey was conducted in the subject districts to compile Origin-Destination (OD) data of traffic flow in the districts. Then, the road network of the subject districts and traffic signal phase data were digitized to carry out microscopic traffic simulation and checked for reproduction accuracy of the current situation. The results confirmed that simulation reproduces the traffic conditions of the districts with sufficient precision. Furthermore, we prepared several hypothetical proposals for the road development and evaluated with the same simulation system as to how the traffic situations would be had those proposals been implemented. As a result it was demonstrated that the original goals can be achieved by developing the road within the given constraints.

GIS-based Forecast of Landscape Changes with the Ito Land Readjustment Project

The purpose of the present research is to attempt consolidation of geographic information into the GIS regarding the Ito Land Readjustment Project presently being implemented in northern Kyushu in Japan, and forecast the landscape changes before/after comparison of the project. First, the topographic map, 50-meter mesh digital map (elevation), aerial photograph, land use map, project plan, land use zone plan, district plan, substitute lot plan and other geographic information of the project district were collected from various sources and systematized. Thereafter the data were aggregated using ArcGIS. Next, building and structure data before and after the project were prepared and height data of these buildings and structures were combined with the land elevation data. Then, the major view point fields in the district were selected, to examine the extent of the change of the visibility areas from these view point fields before and after the project. Moreover, focusing on the mountains in the visibility areas, we forecasted how much the visibility area of the mountains would decrease at each view point field after construction of the buildings and structures in the project implementation. Finally, we showed 3-D images of the project district using ArcScene, and investigated the extent of visibility of the mountain range sky line from each view point field as before/after comparison of the project.

Validation of Platelet Counting Accuracy With the Celltac F Automated Hematology Analyzer

Rapid and accurate analysis of platelet count plays an important role in evaluating hemorrhagic status. Therefore, we evaluated platelet counting performance of a hematology analyzer, Celltac F (MEK-8222, Nihon Kohden Corporation, Tokyo, Japan), that features easy use with low reagent consumption and high throughput while occupying minimal space in the clinical laboratory. All blood samples were anticoagulated with dipotassium ethylenediaminetetraacetic acid (EDTA-2K). The samples were stored at room temperature (18^C–22^C) and tested within 4 hours of phlebotomy. We evaluated the counting ability of the Celltac F hematology analyzer by comparing it with the platelet counts obtained by the flow cytometry method that ISLH and ICSH recommended, and also the manual visual method by Unopette (Becton Dickinson Vacutainer Systems). The ICSH/ISLH reference method is based on the fact that platelets can be stained with monoclonal antibodies to CD41 and/or CD61. The dilution ratio was optimized after the precision, coincidence events, and debris counts were confirmed by the reference method. Good correlation of platelet count between the Celltac F and the ICSH/ISLH reference method (r = 0.99, and the manual visual method (r= 0.93) were obtained. The regressions were y = 0.90 x+9.0 and y=1.11x+8.4, respectively. We conclude that the Celltac F hematology analyzer for platelet counting was well suited to the ICSH/ISLH reference method for rapidness and reliability

Strength-enhanced Sn–In low-temperature alloy with surface-modified ZrO₂ nanoparticle addition

Low-temperature packaging is essential for the widespread use of flexible electronic devices, and Sn–In eutectic alloys have attracted considerable attention because of their low melting temperatures. However, these alloys have a lower strength compared with other types of solder alloys. This study aimed to investigate the effect of adding nanoparticles on the mechanical strength of Sn–In eutectic alloys while keeping their melting temperature unchanged. ZrO₂ nanoparticles coated with NiO (NiO/ZrO₂ nanoparticles) were utilized to strengthen Sn–In eutectic alloys with a high dispersity. Sn–In composite alloys reinforced with NiO/ZrO₂ nanoparticles were fabricated, and tensile strength evaluation and microstructure observations were conducted. The experimental results showed that the addition of nanoparticles to the Sn–In eutectic alloys did not change their melting behavior. The tensile strength of the Sn–In composite alloys reinforced with NiO/ZrO₂ nanoparticles increased by up to 35.6%, which was attributed to grain refinement and dispersion strengthening. Even after thermal aging at 60 ºC, the Sn–In composite alloys reinforced with NiO/ZrO₂ nanoparticles showed a 1.11 times higher ultimate tensile strength than that of the non-aged, non-reinforced eutectic alloy, despite grain coarsening. This was attributed to the contribution of dispersion strengthening. These results indicate that the addition of NiO/ZrO₂ nanoparticles is an effective method to improve the strength of low-melting-temperature alloys.The version of record of this article, first published in Journal of Materials Science: Materials in Electronics, is available online at Publisher’s website: https://doi.org/10.1007/s10854-023-11344-
