Introduction Ingestion of foreign bodies implies a 35% risk of possible complications, which are associated with their type (blunt or sharp) and their size. Although in most of them, it is expected that they pass along the gastrointestinal tract without difficulty or complications, the management will depend on the characteristics of the swallowed object, time of evolution and symptoms of the patient. Case description We present the clinical case of a 58-year-old female patient with a recent gastric bypass surgical history, who accidentally ingested a piece of dental equipment two months earlier during a dental procedure, remaining asymptomatic until she came to our office. In radiographic controls for confirmation, location and evolution, the presence of a 2 cm sharp object was evidenced, apparently located in the cecal appendix, which does not progress distally. For the management, initial expectant management was proposed, which was completed with therapeutic colonoscopy for its extraction, the technique recommends that the sharp object should be grasped by the pointed end, distal to the wall, which reduces the risk of perforation related to the procedure or damage of the mucosa during extraction, the case is completed with successful resolution and without complications. Conclusion Less invasive therapeutic management such as colonoscopy should be considered first line in this type of case, when there are no signs or radiological findings of perforation or clinical instability, due to its low incidence of complications and a high success rate.

This paper investigates the integration of laser profile sensor to an industrial robotic arm for automating the quality inspection in manufacturing processes that requires a manual labour intensive work. The aim was to register the measurements from a laser profile sensor mounted on a six degrees-of-freedom robot with respect to the robot base frame. The registration is based on a six degrees-of-freedom calibration, which is an essential step for several automated manufacturing processes that require high level of accuracy in tool positioning and alignment on one hand, and quality inspection systems that require flexibility and accurate measurements on the other hand. The investigation compromises of two calibration procedures namely the calibration using a sharp object and the planar constraints. The solution of the calibration procedures estimated from both iterative and optimization solvers is thoroughly discussed. By implementing a simulation platform that generates virtual data for the two procedures with additional levels of noise, the six-dimensional poses are estimated and compared to the ground truth. Finally, an experimental test using a laser profile from Acuity mounted on Mitsubishi RV-6SDL manipulator is presented to investigate the measurement accuracy with four estimated laser poses. The calibration procedure using a sharp object shows the most accurate simulation and experimental results under the effect of noise.

During excavations carried out in Ostrów Tumski by the Institute of Prehistory of the Poznań University, a small collection of utensils was found with incised or scratched motifs which are reminiscent of decorations (Figure1). The collection includes an early medieval mug (9th – mid-10th c.; Figure 2:1) as well as jars and a plate (?; 16th c.; Figure 2:2-4) with mysterious signs placed on the receptacles before they were fired (incisions: receptacle 1 and 4) and in the course of use thereof (scratched with a sharp object: receptacle 2 and 3). They were excavated in the ducal garden next to the palace and sacral complex (receptacle 1) and the Gothic St. Mary’s church and the adjacent cemetery (receptacle 2) as well as in the northern part of the island (receptacles 3 and 4). They were excavated from cultural layers (receptacle 1), from a well’s thill (receptacle 2), a wooden waste pond where fish were kept (?; receptacle 4) and a backfill of another well (receptacle 3). On the early medieval mug, where the neck becomes a body, it the middle of its circumference, parallel to the receptacle’s edge, there are signs in the form of a vertical line, a square, another vertical line topped with tiny parallel incisions and two crossing lines incised with a sharp object in a dried utensil before it was fired (Figure 3:1). On the upper part of the body of an almost completely preserved jar, four crossing lines were scratched to form a star, a loop, three intersecting lines – a star, the letter “Y” with three perpendicular lines in the lower part and, slightly lower, a boat /a crescent (?; Figure 3:2). On another jar, in the upper part of its body, next to the handle, a sharp object was used to scratch an inscription made of 6-7 “letters” (Figure 3: 3). At the bottom of a bowl (?), a potter incised with a sharp object a lily and an anchor cross. While only four specimens have been excavated in Ostrów Tumski in Poznań, and the signs are hard to interpret, an attempt can be made to explain the reasons why they were placed on the receptacles. The incisions on two of them were made before the receptacles were fired, hence they can be attributed to the potters’ work. In the case of the mug (Figure 2:1; 3:1), the fact that it was made by the same person was emphasized. The act of incising the bottom of the other utensil (Figure 2:4; 3:4) may have somethingto do with it being made for a specific group of users. On the other hand, the two remaining receptacles were scratched when they were ready so they were marked by the owners at the expense of the utensils’ looks. The jug was preserved almost intact (Figures 2:2; 3:2; 4) and could hold 2 litres of liquid. It is covered with symbols meaningful to its owner, perhaps identifying him/her. A piece of the jug (Figures 2:3, 3:3) bears an inscription which, with some caution, may be interpreted as dialectal words of German or Dutch origin, meaning “my (drinking) utensil”. Irrespective of the correctness of “deciphering” the scratched signs, these are undoubtedly unique hand-written inscriptions from the second half of the 16th century. If anything, it is a good reason to devote attention to them.

The occurrence of a tire leak in the middle of a trip can often be caused by many things, such as being hit by a sharp object, the age of the tire is too old, leaking in the former patches, or it can be caused by others. These factors make vehicle users panic and think to immediately find the nearest tire repair location. Almost everyone has a smartphone where there is a Google Map application by utilizing GPS technology so as not to get lost when driving, with GPS technology can be estimated the distance between one location and another. The purpose of this study is to produce a GIS mobile application that provides a tire patch location search feature with information, so that it is expected to be useful for vehicle users if they experience a tire accident or erupt on the road. The workshop information that is presented is the opening / closing time of the workshop, there are nitrogen added facilities or not, tubeless tire patches, can repair motorcycle tire patches or can also tire the car and the contact of the workshop owner, so you can directly contact the nearest tire patch. The results of testing the user's response to the use of the application indicate that the application is useful.
