Veterinary students learning to perform elective ovariohysterectomy (OVH) and castration procedures have traditionally been taught by a few instructors supervising many student groups simultaneously. This study, using a historical control group, explored the impacts of having a dedicated instructor with each student group for anesthetic induction and an entire surgical procedure. Our hypothesis was that preparation, surgical, and anesthesia times would be shorter and, consequently, post-operative recovery times would be shorter with a dedicated instructor compared to traditional methods. Anesthesia records of dogs undergoing elective surgery by third-year veterinary students were reviewed over 3 consecutive years. Traditional instruction was used in year 1 (Y1), and a dedicated instructor per student group was used in year 2 (Y2) and year 3 (Y3). Anesthesia time, surgical time, recovery time, and pre- and post-operative rectal temperature were analyzed, and a stepwise regression model was developed for factors influencing recovery time. Of 206 records reviewed (Y1, 33; Y2, 98; Y3, 75), there were 101 OVH procedures and 105 castration procedures. Preparation, surgery, and anesthesia times were longer in animals undergoing surgery in Y1, when the traditional instruction method was used. Recovery time was not influenced by instructor assignment. Using dedicated instructors to teach OVH and castration to third-year veterinary students decreased overall anesthesia time by 36 to 49 minutes for OVH and 29 to 32 minutes for castration. A teaching model of dedicated instructors requires excellent coordination between surgeons and anesthesiologists to ensure that a similar number of animals can undergo procedures in the time allotted for teaching.

In the last three decades, relevant research has rapidly increased in tandem with the global popularity of TOD (transit-oriented development) initiatives. It is vital to thoroughly summarize this research and investigate its development trends for sustainable cities. The advent of bibliometrics has given rise to a new method of conducting systematic reviews. We wish to illustrate the evolution of the TOD field by applying scientometrics, with the aim of revealing trends in this field and establishing a scientific classification system. We employ visualization software such as VOSviewer and CiteSpace to conduct bibliometric analyses on TOD-related publications from the WOS database from 1994 to 2021. Potential TOD-related research hotspots and cutting-edge research trends are thoroughly examined. The results indicate that TOD research topics are diverse, with hot topics related to land use, built environment, travel behavior, etc. The regions studied in TOD research are mostly metropolitan areas. Based on a modest number of starting keywords, this strategy can be used to build a more relevant and deeper research network. Through expanding the research content and improving research methods, this paper can provide insights into identifying the evolution of TOD research in different locations of the world, as well as provide a reference for the application and implementation of TOD strategies.

Japan is currently leading the world in many aspects of facade design and cladding technology development. Many buildings feature the latest technological and environmentally friendly concepts that provide Japanese architects with new possibilities to create impressive and innovative schemes. However, despite such advances and designs, facade engineering in Japan is still problematic. The reasons generally stem from the fact that this field is still evolving, and the function of the facade changes from project to project. In addition, the exact role of the engineer in facade design has yet to be clearly established. In this paper, three models will be presented and discussed: 1) facade engineering managed by general contractors; 2) facade engineering supported by specialized subcontractors; 3) facade engineering through collaboration between architects and engineers. We put Japanese facade engineering into better perspective by analyzing the status of the current field of facade engineering. As this is a developing field, new models must be established. Until that is accomplished, Japanese design and engineering of facades will remain divided and inconsistent. This paper highlights the causes of the problems and hopes of proposing a possible alternative for the future.
