The purpose of this report is to demonstrate the potential of university facilities as venues for international conferences, based on JNTO data, which is an international conference indicator. The survey revealed that approximately 30% of international conferences were held at university facilities. While the number of university facilities used as venues is smaller compared with conference centers, they were frequently utilized for hosting small-scale international conferences. Further, a small number of international conferences were organized in collaboration with facilities near the universities or historical buildings, indicating the potential for expanded utilization through regional partnerships.

In response to the reexamination of the upper limit of minor additional constituents in Portland cement, the effect of the amount of minor additional constituents in Portland cement on the activity index test results of micro powder for ultra-high strength concrete was examined. As a result, it was confirmed that even if the mixing ratio of the minor additional constituents was increased from the current JIS upper limit of 5% to twice that amount (10%), the activity index test results did not change significantly.

New admixtures have been developed for high-fluidity, super-low shrinkage concretes. The properties of fresh and hardened high-fluidity, super-low shrinkage concretes using these admixtures were examined in laboratory experiments. It was found that the concretes using these admixtures have the effect of improving carbonation resistance by the experiments. Furthermore, the cause or mechanism was examined, and it was found that the amount of pores larger than 400 or 500 Å was reduced. It is expected that the concretes will have high durability not only in terms of improving crack resistance by reducing shrinkage, but also in terms of improving carbonation resistance.

Experimental investigations were conducted on flexural performance of reinforced concrete (RC) beams with tension sides strengthened with slurry infiltrated fiber concrete (SIFCON) plate. As a result, we reached the following conclusions: (1) Ultimate load of RC beams can be raised nearly twice as large as that of un-strengthened RC beams by this strengthening method. (2) Peeling of SIFCON plate can be prevented up to ultimate load only by adhesive bonding. (3) There is a problem that RC beams strengthened with carbon fiber reinforced plastic plate fail brittlely due to plate-peeling. However, this technique has a possibility of solving the problem.

This report uses Kamo in the 1955s as an example to clarify the relationship between Gangi-Dōri and regular markets. After 1955, from the perspective of ensuring traffic safety, the regular markets that had been held on the road were moved to Gangi-Dōri, and it began to be used as safe commercial space with face-to-face stalls. After that, the road was used exclusively as a road for automobiles, Gangi-Dōri became more important as a sidewalk, and the regular markets were completely relocated.

The authors conducted literature surveys of the 1889 Kumamoto earthquake and presented in the former papers, in order to understand the background of the disaster of 2016 Kumamoto earthquake. On new year’s day of 2024, the destructive earthquake occurred in Noto Peninsula. In this paper we performed literature surveys on the 1933 Noto peninsula earthquake, one of the previous events, referring reconnaissance reports and newspaper articles at that time. Detailed damage by municipalities was clarified and listed. Situation and process of human casualties were also traced with newspaper articles.

This paper analyzes land-use management issues on excavating sites of grave and rock from a viewpoint of restoration and keeping proper land-use and conversion into another land-use especially for urban land-use. Therefore, this study focuses on conversion cases of excavated sites in the three major metropolitan areas in Japan. This paper analyzes on land ownership transition before and after the excavation. In addition, several case studies of land-use conversion by original forest owners were conducted to analyze the subject of land use adjustments and environmental issues.

In recent years, indoor advertisement has increased in some areas. This study aims to clarify the effectiveness and actual usage of indoor advertisement regulations and explore the state of it. As a result, 6.0% of municipalities regulate indoor advertisement through outdoor advertisement ordinance, and the ratio is increasing. The effects of regulating indoor advertisement are that they allow indoor activities to be expressed and that they can guide the integrated landscape of outdoor and indoor areas. It is considered important to continuously inform the public and create an environment that does not allow violating advertisement to be displayed.

To make a specific ceiling earthquake resistant, we isolate the ceiling and wall surfaces to ensure the original acoustic performance of the design, place anti-vibration rubber bearings at the collision points between the ceiling and wall and analyzed the collision phenomenon between the anti-vibration rubber and the wall. We modified the Hertzdamp model, which can appropriately evaluate the current state of collisions, and used a method applied to a structural analysis model that takes dissipated energy into account, to rationally set the design seismic intensity of the ceiling surface and apply it to the renovation of an actual project.

This study aims to examine the ideal state of facilities in the era of community coexistence, taking into account the historical context of deinstitutionalization. It will elucidate the attributes of residents at Facility A, such as age, type and degree of disability, the support systems in place, the usage of the building environment, and the changes in relationships with the community.
