  • Background: Computed tomography urography (CTU), based on the excretion of contrast medium after its injection, allows visualization of the renal parenchyma and the renal collecting system. Objectives: To determine the optimal contrast medium dose allocation ratio to apply in split-bolus CTU in dogs. Methods: This prospective, experimental, exploratory study used 8 beagles. In 3-phase CTU, unenhanced-, nephrographic-, and excretory-phase images were obtained with a single injection of 600 mg iodine/kg iohexol. In split-bolus CTU, two different contrast medium allocation ratios (30% and 70% for split CTU 1; 50% and 50% for split CTU 2) were used. Unenhanced phase image and a synchronous nephrographic-excretory phase image were acquired. Results: Although the attenuation of the renal parenchyma was significantly lower when using both split CTUs than the 3-phase CTU, based on qualitative evaluation, the visualization score of the renal parenchyma of split CTU 1 was as high as that of the 3-phase CTU, whereas the split CTU 2 score was significantly lower than those of the two others. Artifacts were not apparent, regardless of CTU protocol. The diameter and opacification of the ureter in both split CTUs were not significantly different from those using 3-phase CTU. Conclusions: Split-bolus CTU with a contrast medium allocation ratio of 30% and 70% is feasible for evaluating the urinary system and allows sufficient enhancement of the renal parenchyma and appropriate distention and opacification of the ureter, with similar image quality to 3-phase CTU in healthy dogs. Split-bolus CTU has the advantages of reducing radiation exposure and the number of CT images needed for interpretation.

  • The actin cytoskeleton plays fundamental roles in ciliogenesis and the actin depolymerizing factor destrin regulates actin dynamics by treadmilling actin filaments and increasing globular actin pools. However, the specific developmental roles of destrin in ciliogenesis have not been fully elucidated. Here, we investigated the function of destrin in ciliogenesis using Xenopus laevis and human retinal pigmented epithelial (hRPE1) cells. We discovered the loss of destrin increased the number of multiciliated cells in the Xenopus epithelium and impeded cilia motility. Additionally, destrin depletion remarkably reduced the length of primary cilia in the Xenopus neural tube and hRPE1 cells by affecting actin dynamics. Immunofluorescence using markers of ciliary components indicated that destrin controls the directionality and polarity of basal bodies and axonemal elongation by modulating actin dynamics, independent of basal body docking. In conclusion, destrin plays a significant role during vertebrate ciliogenesis regulating both primary and multicilia development. Our data suggest new insights for understanding the roles of actin dynamics in cilia development.

  • This study attempted to investigate the changes in the perception of local government officials about agricultural infrastructure improvement projects due to the financial policy changes. A total of 141 local government officials were surveyed on the priority, the current status of the agricultural infrastructure improvement projects. Irrigation facilities renovation project and Small drainage improvement project had generally high priority, while Support project of cultivation basis for upland crops in paddy, Large scale land readjustment project, and Upland infrastructure improvement project had low priorities. After the introduction of the block grant system, agricultural infrastructure improvement projects had often been conducted by collecting opinions from local residents. The officials in charge of local governments recognized that the agricultural infrastructure improvement projects were reduced due to lack of financial resources and project potential sites. In response to the changes in the agricultural infrastructure improvement projects, most of the surveys showed that the influence of cities and provinces was strengthened. In addition, respondents most needed to improve the subsidy rate and there were a large number of cases requiring differential support to meet the characteristics of the local government. Therefore, it will be necessary to present a new perspective on the agricultural infrastructure improvement projects and to suggest differentiated projects for each regions.

  • As practicalization and commercialization of the technologies invented from the national R&D(Research & Development) project has been emerging as an important issue, the need for a tool for R&D project management has been increased. Technology Readiness Levels model(TRL) has currently been used for R&D project management because it provides distinctive definition of the nine levels in the progress of technology development starting from the basic research level to the utilization level. However, it is difficult to adopt the model for a large-scale national R&D project in which multiple research projects are involved simultaneously. In addition, TRL demands evaluation of research projects done by relevant experts and offers no specific measures determining the level of technology development. This study uses Delphi method to develop the measurement system helping to determine technology readiness levels for the technologies invented in a large scale national R&D project. The proposed model includes definition and measurement scles for each level in TRL.

  • Knowledge management (KM) is one of the useful management tools in today's project management (PM) practice, such as construction projects. Nobody can deny the importance of "useful knowledge" always helps organizations and project managers shaping a decision. Due to the trend of globalization, it is now very common that an organization may comprise employees from different countries of distinct national-cultures working together. It is also not uncommon that different projects, within an organization, may have their own organizational-cultures which influence its knowledge repository, transfer process and knowledge strategy. Therefore, it is extremely difficult to align all these cultures and consolidate them to benefit the KM process and PM practice. Organizations and project managers understand that different national-cultural and organizational-cultural factors will create impact on the philosophy of KM process which will subsequently affect PM practice. Those factors may affect interpersonal relations and exchange of knowledge between projects and amongst staff. Systematic KM process can utilize the goodness of different employees from distinct cultures which can eventually drive the organization and projects to success. The purpose of this paper, based upon a case study of a Hong Kong construction company, is to discuss how those cultural factors are linked to KM and what organization and project managers can do to improve the KM process and PM practice.

  • The purpose of this study is to analyze how the orchard scale improvement project affects the profits of apple farmers. For this purpose, the variable profit function of Apple was estimated using seemingly unrelated regression analysis. For the analysis, raw data from the Rural Development Administration's Agricultural Income Survey from 2015 to 2021 were used. Of the 1,009 apple farms, 95 farms participated in the orchard scale improvement project and 914 farms did not participate. The results show that the profits of farms participating in the project were found to be higher than those of non-participating farms, and as the cultivation area increased, profits tended to increase and then decrease. The results also indicated that below a certain size (19,462m2), the profits from project participation appear to be lower. The results of this study can provide useful information to the establishment of government policies and apple farmers who want to participate in the orchard scale improvement project.
