In Japan, the collection and compilation of statistical data on occupational accidents were officially initiated after the promulgation of the Japanese Factory Law in 1911. Since then the data acquisition system for the occupational accident statistics has been developed into a more elaborate and sophisticated system. This report presents a brief historical outline of the data acquisition system for the occupational accidents in Japan. In addition, an international review and comparison of the occupational accident indicators is presented. This analysis is based on the investigation of resolutions of the International Conferences of Labour Statisticians, which is promoted by the International Labour Organisation. Furthermore, necessary cares to be considered in the use of the accident statistics and another development needs in relation to the occupational accident data acquisition system are recommended.
This paper presents a new database for the history of civil engineering. This database for personal computer enables the user to compile various chronological table. This database covers almost all of the chronological tables of the history of civil engineering provided by Japanese investigators, and contains more than 3000 items which are classified by subjects. Through the function of data-processing available in a personal computer, choosing some keywords or some specified theme, various chronological table can be made easily. This paper shows some examples of the chronological tables and attempts to describe the history of civil engineering from a new aspect.
Flood control techniques of the Tokugawa era have not been clear until today. Some preceding relational studies have described that river improvements during the Tokugawa era were conducted by two largest river improvement schools, namely, “Kantouryu ” and “Kisyuryu ” which, accordingly, had directed flood control techniques of the Tokugawa Shogunate. Recent studies have gradually clarified the improvement works in each river in Japan during the Tokugawa era. The results are that “Kantouryu ” and “Kisyuryu ” might not have directed flood control techniques of the Tokugawa Shogunate. To find out these results, more investigation must be done on the river improvement works of the Tokugawa era in each Japanese river. As one of the studies in this new standpoint, this study is aimed at making clear the flood control techniques during the Tokugawa era in Sakawa river running in west Kanagawa Prefecture.
This study is intended to find out the characteristics and the transformations of“Plaza”in Edo City. For this purpose, the macroscopic distribution and the transformation of“plaza”derived from“Kiriezu”and maps of old Edo City were toporographically examined and the site characteristics of“Plaza”were analysed. Besides, the functions of“plaza”were analized and classified.The result of this study are as follows. (1)“plaza”in Edo City were located on several types of“Fuchi”(fringe, edge) such as riverside and interface. (2) Those“plaza”functioned as open space not only for fire prevention but also for transportation, and communication---etc.
This research study comprises a part of the fundamental research being conducted on engineers in Taiwan covering the period of Japanese colonial rule. William K. Burton, in his capacity as Sanitary Engineer, was invited to plan the waterwork system of Taiwan. He was teaching at the Tokyo Imperial University and one of his students was Hamano Yashiro whom he brought with him to Taiwan to be his assistant. He worked in Taiwan from August 5, 1896 untilh e died on August 5 1899. Among his works were the planning of the waterworks of Taipei, Chilong, Taichong and still other places in Taiwan Burton also involved himself in the reconstruction works of streets in Taipei and designed' model housing for the country. Upon his untimely death, his Japanese assistant, Hamano, continued his remaining works. An examination of William K. Burton's projects in Taiwan would readily reveal an aspect of great importance in the process of modernization of Taiwan.(Burton, Waterworks, Taiwan)
Arch bridges built with bricks in Meiji or Taisyo Era were mainly constructed to pass an aqueduct or a road under railway track. We investigated the present state of these old arch bridges in Kansai district and discovered that some of them are spiral brickworks. We recognized, however, this unique structure only in oblique arch bridges. Meanwhile through literature survey on arch bridges constructed in those days, we identified this structure as " Syakakyo " as oblique arch bridges were called in Japanese, which was an engineering technology for construction of an arch bridge as skew to the track direction. In this study, we make clear the designing and working of " Syakakyo ", and reveal the relation between theory and practice of this technology.
The section betweeh Nagahama and Kobe on Tokaido Line is a very important one for tunnel history, because it includes the first railway tunnel ever bored in Japan, and the first railway tunnel completed solely by the force of Japanese engineers. But many of the original tunnels in this territory have been abandoned for repeated relocation or track addition works. This paper describes the history and present state of these tunnels based on field surveys and historical records. For instance, the first Osakayama Tunnel was replaced with a new tunnel following a new route taken Otu and Kyoto in Taisyo Era, and added wuth next tunnels to meet the traffic increase in Syowa Era. This case study reveals that the tunnels was built with various inside shape reflecting the age of their construction.
The way in organizing the Station Plaza is often mentioned as “the adjustment of the means of transportation” and “building the gateway to the city.” In recent years, there has been several movements within the self-governing body regarding a large remodel of the public square around the railway station. During the construction there were often some printed phrases in sight, such as, “The gateway of the city needs to be remodeled.” Yet, when the construction is over all there are tall buildings everywhere and a deck for the pedestrians. Such are the common results found in several cases. Hence, this study will refer to the actual photographs, sketchings and other drawn materials. “Traffic Management” and “Relationship between the City andthe station” are the two points from which we are able to find ideas and skills for accomplishing the plan. In addition that they would offer some hints to the future constructing plans.
