This work discusses and evaluates the use of wireless and multi-sensor based technologies to develop UbiqBIOPARC, a new generation zoological park that has been created based on the zoo-immersion concept. It offers appropriate contextual information to zoo visitors, depending on their preferences and the environment in which they are positioned. It combines the flexibility of the iPhone SDK, the connectivity provided by 3G technologies, the location capabilities of GPS, and the orientation offered by a digital compass integrated in the device. In this document the overall architecture and the implementation steps followed to create this context-aware application are presented. We compare our system with respect to previous ones and demonstrate that UbiqBIOPARC is an example of how innovative context-aware applications can be built with the aid of GPS and compass features. Several real experiments have been carried out in order to evaluate performance and system behavior, and numerical results demonstrate the practicality offered by our application, while providing a quite reasonable performance in terms of delay, usability, and energy efficiency.

Seventy-six animals including cattle, sheep, horses, 6 species of zoo animals were employed for collection of fresh feces in order to detect verotoxigenic Esherichia coli (VTEC) by safe, quick and sensitive PCR-based molecular methods. Bacterial cell disruption with bead-beating followed by bacterial DNA purification with hydroxyapatide chromatography and gel filtration allowed DNA preparation from animal feces with high recovery and purity. A mountain goat was firstly shown by PCR and sequencing to shed verotoxin 2 gene (vt2) that was used to generate vt2 probe and second primer set for nested PCR to attempt more sensitive detection. Most sensitive nested PCR revealed that 45% of tested cattle and 47% of tested zoo animals were VTEC-positive, while least sensitive normal PCR detected VTEC from none of these animals except a mountain goat. Moderately sensitive detection by PCR in combination with hybridization suggested that the VTEC density varied between the VTEC-positive cattle.

An 1-year old male siberian tiger showing severe vomiting and blackish and frothy diarrhea for 3 days were dead in Seoul Zoo. Gross finding at necropsy were small amount of blood were found in abdominal cavity and intestine. In small and large intestine, there were necrosis and detachment epithelial cell of intestinal mucosa in histopathology. The presence of feline panleukopenia virus (FPV) antigen was detected by PCR. In microbiology, E.coli and Enterococcus faecalis were isolated from the stool. This case was diagnosed in death induced by FPV infection according to CBC, histopathology and PCR.

Two adult rock partridges raised in a city zoo were examined parasitologically and pathologically. Two distinctive eggs resembling those of Capillaria and Heterakis were detected in the feces. At necropsy, a markedly-dilated duodenum with severe catarrhal exudates, containing adult worms of Capillaria sp. and Heterakis sp. in the cecum, was observed. Male Capillaria had the cloacal aperture extended almost terminally with a small bursal lobe and an unsheathed spicule with transverse folds without spines. Female Capillaria had a vulva that was slightly prominent and slightly posterior to the union of the esophagus and intestine. The esophagus of the adult Capillaria was more than a half as long as the body in the male, but was much shorter in the female. Based on these morphological features, the capillarid nematode was identified as Capillaria obsignata. The male adult worms of Heterakis was identifiable by 2 dissimilar spicules, a unique morphological feature where the right spicule was considerably longer than the left, which is also a characteristic feature of Heterakis gallinarum. This is the first report of concurrent infections with C. obsignata and H. gallinarium in rock partridges.

A 7-year-old, female snow goose (Anser caerulescens hyperboreus) with history of decreased activity for 2 month died in Daejeon Zoo Land in September 2006. At necropsy, granulomatous pneumonia and hepatomegaly with multiple cysts were observed. Small masses were found in the spleen. Microscopically, fibrinous pneumonia distributed in most of the lung lobe with pulmonary edema and congestion. Especially, granulomatous inflammation with numerous multinucleated giant cells was observed around the dilated bronchi. To confirm the diagnosis, acid-fast (Ziehl-Neelsen method) and periodic acid-Schiff (PAS) staining was performed. Acid-fast staining showed red bacterial colony indicating tuberculosis. PAS staining was also positive enough to diagnose aspergillus spp. co-infection that was an opportunistic fungi occurring in immuno-compromised animals. Based on the above results, we confirmed that the case submitted was diagnosed as avian tuberculosis.

기면 및 호흡곤란 상태로 서울대공원 동물병원으로 내원하여 다음날 폐사한 체중 90 g의 어치를 검사한 결과 양쪽 눈 모두 건조한 딱지로 덮여 눈을 떨 수 없는 상태로 눈꺼풀이 붙어 있었으며, 혀 및 구강내부 점막에 누런 치즈 양 물질이 붙어 있어 계두로 의심되어 PCR 검사를 실시한 결과 국내에서 자연 발생한 계두의 첫 증례로 진단되었다.

A 14-year-old intact male captive leopard (Panthera pardus) first presented with a focal alopecic lesion on the dorsal aspect of the distal one-third of its tail. Although itraconazole was administered, the lesion progressed deeper and became ulcerated due to self-trauma. Due to the wild nature of the leopard, daily dressing of the wound and replacing the bandages without anesthesia became too dangerous, and amputation became necessary. A postoperative tissue sample was submitted for histopathological examination, and tramadol, amoxicillin/clavulanate, and gabapentin were administered. In the days following the amputation, the leopard's appetite significantly decreased, and the patient passed away 18 days later. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma (SCC). In hindsight, had more cells been collected by a fine-needle aspirate (FNA) biopsy or had additional FNA biopsies been performed, SCC might have been diagnosed based on its cytological features rather than delayed histopathological findings. The current study highlights the critical reasons why clinicians may often misdiagnose SCC and the importance of being more aware of potential tumors in ulcerative lesions, which are often incorrectly treated as infectious skin diseases. This is also the first report of cutaneous SCC in a leopard.

This study introduces a prototype for a virtual zoo initiative, aimed at optimizing resource utilization and minimizing animal displacement from their natural habitats. The prototype features a thoughtfully developed three-dimensional representation of an emperor penguin, with animations designed to emulate real-life behaviors. An investigation into file format distinctions for scientific research, encompassing Wavefront(OBJ), Collada(DAE), and Filmbox(FBX) formats, was conducted. The research utilized the Hololens 2 device for visualization, Unity for environment development, Blender for modeling, and C# for programming, with deployment facilitated through Visual Studio 2019 and the Mixed Reality Toolkit. Empirical examination revealed the OBJ format's suitability for simple geometric shapes, while DAE and FBX formats were preferred for intricate models and animations. DAE files offer detailed preservation of object structure and animations albeit with larger file sizes, whereas FBX files provide compactness but may face scalability constraints due to extensive data integration. This investigation underscores the potential of virtual zoos for conservation and education, advocating for further exploration and context-specific implementation.
