The Activity patterns of animal species are difficult to access and the behavior of freely moving individuals can not be assessed by direct observation. As it has become large challenge to understand the activity pattern of animals such as dogs, and cats etc. One approach for monitoring these behaviors is the continuous collection of data by human observers. Therefore, in this study we assess the activity patterns of dog using the wearable sensors data such as accelerometer and gyroscope. A wearable, sensor -based system is suitable for such ends, and it will be able to monitor the dogs in real-time. The basic purpose of this study was to develop a system that can detect the activities based on the accelerometer and gyroscope signals. Therefore, we purpose a method which is based on the data collected from 10 dogs, including different nine breeds of different sizes and ages, and both genders. We applied six different state-of-the-art classifiers such as Random forests (RF), Support vector machine (SVM), Gradient boosting machine (GBM), XGBoost, k-nearest neighbors (KNN), and Decision tree classifier, respectively. The Random Forest showed a good classification result. We achieved an accuracy 86.73% while the detecting the activity.

In these days, we come across a growing interest in animals from various perspectives. Considering that the posthumanistic point of view forms the major stream of postmodern humanities, ethics and philosophies, this paper tries to study the liminality between human beings and animal as appear in postmodern plays. The cases of a middle-aged architect falling in love with a goat (The Goat, or Who is Sylvia? by Edward Albee); An abandoned (human-)dog that encounters his old mistress under the moonlight (A leaseholder by Yoon Young-sun); Coexistence of men, dog, plants in a Country life (White Cherry by Bae Sam-sik); A Mutual sympathy between a swarm of bees and a woman dying of cancer(Bee by Bae Sam-sik) were discussed referring such concepts as 'Otherness' of Derrida, 'Becoming'of Deleuze, 'a bare life' of Agamben and ecological co-existence. In The Goat, the moment of Martin who happened to meet a goat's eyes in a suburbs can be paralleled with that of Derrida who one day found himself caught up with the gaze of a cat in the bathroom while he was naked. They shared the common experience in that they went through the ontological and mysterious abyss that rendered them to raise the question of "Who am I ?" In A leaseholder, a young woman returns to her hometown exhausted by the calculating human society and meet her old time (human-dog). This story reminds us of Agamben's werewolf, Levinas's dog Bobby and Derrida's Zootobiography. He, an abandoned pet, both excluded and included from human society, now appearing as a mysterious human-dog, welcomes, embraces, and comprehends his old mistress and exposes his individual remorses and passions as an animal-subject. In White Cherry, the author describes the coexistence of all the life-beings such as an old dog, a golden bell tree, the deceased daughter and even a fossil remains in a country life. Bee is a story of a beekeeping village where bees were leaving and disappearing. A swam of bees fly down on a woman who was dying of cancer. With physical and spiritual empathy the dying woman helps the swarm of bee to conduct a new birth and a new life.

As pet dogs rapidly increase in number, abandoned and lost dogs are also increasing in number. In Korea, animal registration has been in force since 2014, but the registration rate is not high owing to safety and effectiveness issues. Biometrics is attracting attention as an alternative. In order to increase the recognition rate from biometrics, it is necessary to collect biometric images in the same form as much as possible-from the face. This paper proposes a method to determine whether a dog is facing front or not in a real-time video. The proposed method detects the dog's eyes and nose using deep learning, and extracts five types of directional face information through the relative size and position of the detected face. Then, a machine learning classifier determines whether the dog is facing front or not. We used 2,000 dog images for learning, verification, and testing. YOLOv3 and YOLOv4 were used to detect the eyes and nose, and Multi-layer Perceptron (MLP), Random Forest (RF), and the Support Vector Machine (SVM) were used as classifiers. When YOLOv4 and the RF classifier were used with all five types of the proposed face orientation information, the face recognition rate was best, at 95.25%, and we found that real-time processing is possible.

Digestibility of pet food can affect the health of dog, especially of aged animals. To maintain the health of dogs in an overall good status it is necessary to provide nutritionally balanced food. For example, the digestibility of dogs was known to be decreased along aging. In addition, losing teethes is an often event in aged dogs that could induce a problem to eat a large size dry pet food. Nonetheless, few detailed information is available on the most suited feeding for aged dogs. As part of the nutritional study of food for aged dogs, in this study, we tested whether food type impacts on digestibility on adult versus senior dogs. The methodology to measure the digestibility of nutrients was chosen the index method using chromium oxide. Dogs were fed the same commercial dry or wet diets, which were supplemented with 0.5% chromium oxide. The wet food was prepared by adding twice volume of water in the dry food prior to incubated overnight (14-16 hours) at room temperature. After five days, their feces were collected up to a total weight of > 200 g which was the amount to analyze undigested nutrients in feces as 3 repeats. In the apparent total tract digestibility analysis of the experimental breed, no difference in the digestibility of crude protein, crude fat, crude fiber, ash, and energy was observed regarding the moisture content of the food. Noteworthy, the digestibility of nitrogen free extract was significantly increased in senior dogs fed dry dog food compared with adult dogs fed the same diet, whereas no difference was observed between senior and adult dogs fed wet food. The small breed dogs showed similar results to the experimental breed dogs. However, the digestibility of crude fat was additionally affected by age and food type unlike the experimental breed dogs. This finding suggests that the food moisture content affects the digestibility of nutrients in dogs with aging. Hence, it may be helpful to determine the nutrient contents in foods for senior dogs depending on the food type.

22 dogs (31 eyes) that had treated with trimethoprim-sulfamethoxazole for tear staining syndrome at Snoopy Pet Clinic from October 2000 to September 2002 were reviewed. Of the 22 dogs, 12 were female and 10 male. Their mean (${\pm}$ SD) age was 3.5 (${\pm}\;1.3$) years. The breeds of the dogs consisted of Maltese (8 dogs), Shih tzu (6 dogs), Poodle (5 dogs), Yorkshire terrier (2 dogs), and Mixed (1 dog). The dogs received 30 mg/kg trimethoprim-sulfamethoxazole perorally twice daily for two to six weeks. 26 (19 dogs) of the 31 eyes (22 dogs) recovered completely and did not show relapse at $26{\sim}30$ weeks after treatment. Any complications did not observed. Five eyes of three dogs were not cured. Two eyes (one dogs) of them had not response to medicament and three eyes (two dogs) recurrence but the clinical signs decreased. It was considered that the trimethoprim-sulfamethoxazole was effective for the treatment in dogs with tear staining syndrome.

In the image field, data augmentation refers to increasing the amount of data through an editing method such as rotating or cropping a photo. In this study, a generative adversarial network (GAN) image was created using CycleGAN, and various colors of dogs were reflected through data augmentation. In particular, dog data from the Stanford Dogs Dataset and Oxford-IIIT Pet Dataset were used, and 10 breeds of dog, corresponding to 300 images each, were selected. Subsequently, a GAN image was generated using CycleGAN, and four learning groups were established: 2,000 original photos (group I); 2,000 original photos + 1,000 GAN images (group II); 3,000 original photos (group III); and 3,000 original photos + 1,000 GAN images (group IV). The amount of data in each learning group was augmented using existing data augmentation methods such as rotating, cropping, erasing, and distorting. The augmented photo data were used to train the MobileNet_v3_Large, ResNet-152, InceptionResNet_v2, and NASNet_Large frameworks to evaluate the classification accuracy and loss. The top-3 accuracy for each deep neural network model was as follows: MobileNet_v3_Large of 86.4% (group I), 85.4% (group II), 90.4% (group III), and 89.2% (group IV); ResNet-152 of 82.4% (group I), 83.7% (group II), 84.7% (group III), and 84.9% (group IV); InceptionResNet_v2 of 90.7% (group I), 88.4% (group II), 93.3% (group III), and 93.1% (group IV); and NASNet_Large of 85% (group I), 88.1% (group II), 91.8% (group III), and 92% (group IV). The InceptionResNet_v2 model exhibited the highest image classification accuracy, and the NASNet_Large model exhibited the highest increase in the accuracy owing to data augmentation.

The aim of this study was to estimate of prediction of whelping day and to confirm the accuracy of prediction of whelping day in small pet bitches. The gestation length from the each based on days was $66.64{\pm}2.32days$ ($Mean{\pm}S.D$) when the Cornification index (CI) was over 90% after the first vaginal discharge, $64.65{\pm}2.87days$ from the day of CI peak, $63.46{\pm}1.63days$ from the day of ovulation by progesterone concentrations, and $57.67{\pm}2.43days$ from the first day of cytologic diestrus, respectively. The whelping day was estimated 66 days when the CI was over 90% after the first vaginal discharge, 64 days from the day of CI peak, 63 days from the day of ovulation by progesterone concentrations, and 57 days from the first day of cytologic diestrus, respectively. The accuracy of the prediction of whelping day was 90.0% with a precision of ${\pm}2days$ when the CI was over 90% after the first vaginal discharge, 77.5% from the day of CI peak, 86.2% from the day of ovulation by progesterone concentrations, and 81.2% from the first day of cytologic diestrus, respectively. These results indicated that the prediction of parturition day by vaginal cytology was useful method for management of reproduction and parturition in small pet bitches.

This study was undertaken to determine the normal serial ultrasonographic appearance of the postpartum uterine involution in small pet dogs (Yorkshire terrier and Maltese). Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored by ultrasonography in 12 small pet dogs. Serial ultrasonographic examinations were done daily during the first week, 3 days interval from 8 to 30 days, and weekly from 31 to 100 days postpartum. The excretory period of vaginal discharge in 12 normal bitches of uterine involution was finished completely within 3 weeks postpartum. The short axis shape of the uterus was initially often flaccid-appearing. It varied from circular to polygonal. This lasted until 15.75$\pm$3.84 days postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was a beaded appearance until 30.89$\pm$4.25 days postpartum. After 30 days, it was appeared as tubular shape between placental and interplacental sites. The ultrasonographic image of the postpartum uterus consisted of four echogenicity distinct layers. Uterine wall was represented as very hyperechoic serosa, hypoechoic myometrium, hyperechoic endometrium and anechoic structures of fluid in the uterine cavity until 7 days postpartum. The individual uterine layers were most prominent during the first week postpartum, and they became progressively less distinct throughout the course of uterine involution. The thickness of myometrium was decreased rapidly in the placental sites from 4.47$\pm$1.42 mm at 1 day to 1.92$\pm$0.26 mm at 16 day, and in the interplacental sites from 3.19$\pm$0.61 mm at 1 day to 1.39$\pm$0.61 mm at 16 day. And it was decreased slowly until 94 day and was been minimum thickness at 94 day. The thickness of endometrium was also decreased like that of myometrium. The uterine diameter in the placental sites was decreased from 22.28$\pm$3.01 mm at 1 day to 16.11$\pm$1.46 mm at 7 day, and in the interplacental sites was decreased from 13.65$\pm$2.34 mm at 1 day to 9.41$\pm$1.59 mm at 7 day postpartum. From 7 day to 93 day, the change of diameter was more and more slow. At 94 days postpartum, the uterine diameter was 5~6 mm both placental and interplacental sites, and the uterine horns were uniform hypoechoic, tubular structures without enlargement. Therefore, complete involution of the uterus occurred at 94 days. It was concluded that normal post partum uterine involution in small pet dogs appeared to be completed 94 days postpartum by gross findings such as vaginal discharges, and by ultrasonographic findings, uterine shape and echogenicity.
