Recently, the number of pet-owning households drastically increased and many people took their pets as lifelong companion animals and look after them like their children. Pet business has continued to increase gradually and the need for pet supplies has increased, too. Though there are a variety of pet supplies in pet dog market which takes up many parts in the pet market, there is no design guideline on pet supplies. Thus, there are many wrong pet supplies design created by wrong idea of people. Therefore, this study aims to suggest the guideline on pet supplies design focusing on the pet-monitoring system among the various pet products. So, the pet-monitoring robot was designed to monitor pet simply using smartphone anywhere on the trip and feed by using bowl that control the signal. This study figured out types and function of existing IP camera, reflected the behavior and physical characteristics of pets and suggested the design guideline which is minimum required as pet-monitoring products. Also, trial product for which design guide was applied was produced to observe the pet behavior and identify problems while operating trial product. However, there was limit in securing data and study period to examine the satisfaction of various pets since the subject of this study was dog and it's required to conduct follow-up study by observing continuously and improving the problems in future to secure more data.

The aim of this study was to identify factors that affect the treatment duration and to predict the duration of forced eruption in impacted maxillary canines using panoramic radiographs and cone-beam computed tomography. This retrospective study was performed by reviewing medical records and radiographs of 73 patients (93 impacted maxillary canines) from the age of 8 to 18 years who were treated with surgical and orthodontic interventions on impacted maxillary canines from January 2012 to December 2020 in Ajou University Dental Hospital. Stepwise multiple regression analysis showed that the distance between the canine cusp tip and the occlusal plane, mesio-distal location, bucco-palatal location, patient's age, and use of rapid palatal expansion are significant factors with regard to the duration of forced eruption. There was a statistically significant correlation of the treatment duration with the angulation between the axis of the canine and the occlusal plane and unilateral or bilateral impaction. It can be concluded that the duration of forced eruption in impacted maxillary canines could be shorter when the impacted canine is closer to the occlusal plane and located in the lateral incisor or canine area, buccal or middle, the patient is younger and uses rapid palatal expansion.
