    In this paper, we describe the contraction-annihilated Macaulay dual generators for complete intersection ideals defined by complete homogeneous symmetric polynomials of successive degrees. We also provide the first syzygy of the associated graded ring of each of these complete intersections with respect to the last variable. Using this, we prove that each of these complete intersections possesses the strong Lefschetz property, provided that the coefficient field of the polynomial ring has characteristic 0.

    Taijun Takeda modernizes Shiki in Shiba Sen. The term ‘modern era’ in Shiba Sen includes a dual-layered present: the present in Shiki and the wartime present of the Sino-Japanese War and World War Ⅱ. Its historical perspective is based on Buddhist concepts of time. This is an allegory that interprets the wartime present and the realities of Japan by reflecting the structure of Shiki. The work is a form of bricolage.

    As Japan's working population declines, technological innovations such as DX, AI, and IoT based on computer and communication technologies are required. Therefore, National Institute of Technology (KOSEN), Kumamoto College has formed a group called DXNP (Digital Transformation Network Project) as one of the research project groups of faculty members, and has been working on its activities. This paper mainly reports on the activities of this group in 2023.

    This is a simple method of obtaining the coordinates of a reference point marker without spending a lot of time or money, even for beginners with no surveying skills. The small terrain included buildings, roofs, trees and iron poles in the vicinity, making the area unsuitable for flying a drone. The first surveying method used was to prepare a compact box with a number of marker labels attached, and to record the coordinates of each marker on a scale. Photographs were then taken with the camera around the small landforms, taking care to ensure 60-80% overlap. The photographic data was then analysed by software and the measured distance between two points was compared with the distance calculated by the software to compare the error near the reference point marker with the error at a distance. The results showed that the average error near the marker was 0.190 mm and the average error at a distance of approximately 3 m from the marker was 5.67 mm, indicating that the error near the marker was small and the error increased as the distance from the marker increased. In other words, it was found that a small area of about 5 m square can be surveyed with an accuracy of about 5.6 mm at the edge of a dense area with obstacles that are difficult to fly over with a drone.
