Importance of absorbable surgical sutures for the prevention of stitch abscess after surgery in patients with oral squamous cell carcinoma
To elucidate the significance of absorbable surgical sutures in the occurrence of stitch abscess after surgery in patients with oral squamous cell carcinoma (SCC). The subjects were 251 patients who underwent excision and/or reconstruction and/or neck dissection for oral SCC using absorbable surgical sutures. Detection rates and characteristics of patients with stitch abscess were retrospectively evaluated by comparing between our present and previous data. There was only one stitch abscess among the 251 patients. A significant difference in the incidence of stitch abscess was found between the present data and our previous data. Of course, no significant correlations were found between the occurrence of stitch abscess using absorbable surgical sutures and the various factors seen in our previous analysis. A complete switch of surgical sutures from silk to absorbable surgical sutures is needed for surgery in patients with oral SCC
Wearable Interfaces for a Video Diary: towards Memory Retrieval, Exchange, and Transportation
In this paper, we discuss wearable interfaces for a computational memory-aid useful in everyday life. The aim of this study is to develop a Video Diary system with vision interfaces to aid in memory retrieval. The Video Diary system provides users with “Memory Retrieval, Exchange, and Transportation ” through four types of indexes: 1) through the user’s location, 2) through real world object(s), 3) through keyword(s) and 4) through the use of a summary or “the story of the day. ” The authors have developed the following two systems to achieve the above indexes: 1) a Residual Memory system, 2) a Ubiquitous Memories system. Residual Memory can index a user’s location automatically by analyzing a video recorded from a wearable camera for “Memory Retrieval. ” Ubiquitous Memories provides users with the ability to associate augmented memories with real world objects for “Memory Exchange. ” We have integrated the above two systems for “Memory Transportation. ” We believe that the above interfaces can be integrated into the Video Diary system.
Nice2CU: managing a person’s augmented memory
In this paper, we propose a feasible wearable system named Nice2CU to manage a person’s augmented memory. For managing a person’s augmented memory, an “easy registration ” method and an “automatic update ” method are necessary. We have designed a prototype system using a “Card and Mirror ” interface
View angle evaluation of a first-person video to support an object-finding task
The aim of this paper is to investigate an effective view angle of “a first-person video” when a user tries “an object-finding task”, a task to find a target object in his/her everyday environment. The first-person video means a video recorded by a head-mounted camera of a wearable system worn by the user. The objectfinding task can occur when the user forgets where he/she last placed the target object. The first-person video can include some contexts of the event. There are two important contexts required by the user to find the target object; one is “the action” that he/she placed the target object, and the other context is “the location” that the object was placed. The view angle of a lens, which is employed by the camera device, affects the width and the time length of the first-person video. It is important to investigate appropriate range of the angle so that the user can recognize those contexts by watching the first-person video. We conducted experiments that subjects evaluate videos in several width of the angle. We then found that the range of the view angle is from 115 to 125 in degree.http://library.naist.jp/mylimedio/dllimedio/show.cgi?bookid=100043509&oldid=8085
Functional evaluation of a vision-based object remembrance support system
People tend to forget where they placed an object, which is necessary to achieve a certain task, in their everyday circumstances. To support a user’s object-finding tasks, we have proposed a wearable interface system named ”I’m Here!” The system manages Augmented Memories, a video database of the user’s viewpoint labeled with previously registered objects, to display the last video of the target object held by the user. In this paper we evaluate the function of the system with laboratory experiments, and discuss the positive and negative effect of the system with the experimental results.http://library.naist.jp/mylimedio/dllimedio/show.cgi?bookid=100039413&oldid=7252
I’m Here!: A Wearable Object Remembrance Support System
Abstract. In this paper we propose a wearable vision interface system named “I’m Here! ” to support a user’s remembrance of object location in everyday life. The system enables users to retrieve certain information from a video database that has recorded a set of the latest scenes of target objects which were held by the user and were observed from the users’ viewpoint. We propose the object recognition method to associate the video database with the name of objects observed in the video. The offline experiments demonstrate that the system is useful enough to recognize the objects.
