Because of development of information communication and multimedia technology, the focus of M2M(Machine to Machine) intelligent network, multimedia collaboration environment, and transportation safety service is increased. This paper describes a multimedia replicated architecture based on Shepherd environment for transportation safety service. The relationship of information collection and utility is relationship of man to man, but is developed object to object by information communication and control system. This paper suggests a design of multimedia cyber collaboration environment based on M2M. This structure can make multimedia collaboration environment and fault tolerance, so on easily. Because M2M system does not affected to all system in spite of occurring to fault to a node or resource, it has a good condition for design of transportation safety service running on M2M.

Background: The aim of the study is to evaluate the effectiveness of thermographic monitoring, using the temperature changes of perianal and perivulvar areas for the determination of estrus in Anatolian Shepherd bitches. Fifteen bitches were used in the study. Blood and vaginal smear samples were collected and thermographic monitoring of perianal and perivulvar areas were carried out starting from proestrus to early diestrus. Also, external signs of estrus were investigated. Smear samples were evaluated by light microscopy after Diff-Quik staining method and superficial and keratinized superficial cells were determined as percentage (S + KS%). Progesterone and luteinizing hormone measurements were done by radioimmunoassay. The difference in temperature between perianal and perivulvar areas was evaluated through thermographic images by FLIR ResearchIR Software. Results: According to the results obtained from the study, differences between progesterone and S + KS% were statistically significant (P < 0,05). Although temperature showed increase and decrease with progesterone and S + KS%, the differences were not important statistically (P > 0,05). Serum luteinizing hormone levels did not sign any difference (P > 0,05). Conclusions: As a result, thermographic monitoring alone is not enough for estrus detection in Anatolian Shepherd bitches. However, it can be used to assist the actual estrus detection technique in terms of providing some foreknowledge by evaluating the differences in temperature.

A 4-year-old, spayed female German Shepherd dog (GSD) weighing 22.4 kg was referred to Chungnam National University Veterinary Medicine Teaching Hospital with the chief complaint of a cardiac murmur. A continuous murmur was detected at the left basilar region upon auscultation. In the thoracic radiographs, slight bulging of the aorta, the main pulmonary artery, and the left atrium were observed. Echocardiography revealed continuous turbulent flow directed from the main pulmonary artery towards the pulmonary valve and consistently within the main pulmonary artery. Based on all the results, a diagnosis of type II A patent ductus arteriosus (PDA) was made, and plans were established to treat it with transcatheter occlusion. Transcatheter occlusion was performed using a vascular plug and successfully deployed at the PDA. The patient did not exhibit any complications. GSDs are relatively less common compared to small-breed dogs in South Korea. Considering that GSDs are predisposed to PDA, it is crucial to periodically assess the presence of PDA through auscultation and echocardiography, even in the absence of clinical signs. Transcatheter occlusion using a vascular plug can be an option for treatment and can yield favorable outcomes.

A 3-year-old, 20.6 kg, neutered male German Shepherd dog was referred to Kyungpook National University Veterinary Medicine Teaching Hospital. Clinical examination revealed chronic diarrhea for 6 weeks and a non-tender, distended abdomen without lethargy, anorexia, and vomiting. Diarrhea was watery and had a waxing and waning course despite symptomatic treatment. A complete blood count identified mild leukocytosis and mild anemia. Serum biochemistry analysis showed elevated alanine aminotransferase and aspartate aminotransferase levels, and mild hypoalbuminemia. Abdominal ultrasound examination revealed mixed echogenicity with absent blood flow at the caudate process of the caudate liver lobe and a small amount of ascites. Computed tomography revealed torsion of the caudate process of the caudate liver lobe and spleen and gas dilatation of the intestine. After establishing a diagnosis of organ torsion on imaging, we deemed the condition an emergency and immediately performed surgery. Given that laparotomy confirmed organ torsion, liver lobectomy, total splenectomy, and prophylactic gastropexy were conducted. The patient was discharged 11 days after surgery without complications. In general, liver lobe torsion and splenic torsion are uncommon in dogs and present with nonspecific clinical signs, such as abdominal pain, lethargy, anorexia, and vomiting. In the current case, torsion of the caudate liver lobe and spleen occurred without other clinical signs except for a distended abdomen. Moreover, no reports in dogs have demonstrated the simultaneous occurrence of both diseases.

This study was carried out to estimate the possibility on the removal of phenols and anilines, which were contained in pulp or dye waste water, and the reusability of plant materials, shepherd's purse and turnip. Most of phenols catalyzed with shepherd's purse were removed more than 90% in the presence of $H_2O_2$, and the removal was ranged from 53.1% for 2,6-DMP to more than 99% for 2,4,6-TCP when turnip was used as catalysts. The removal of anilines catalyzed with shepherd's purse was ranged from 42.2% for 2-CA to 78.7% for 3,4-DCA in the presence of $H_2O_2$, and in case of turnip, from 31.5% for 2-CA to 90.0 % for 2,4-DCA. The reuse of plant materials was proved to be possible for not only the batch method but also the continuous method. No decreasing removal was observed during 30 cycles in waster water contaminated with 100ppm of 2,4-DCP. However, it was observed that the removal was decreased with increasing the number of cycles in higher concentration of 2,4-DCP(800ppm). Therefore, it could be suggested that the number of reusable cycles depends on the initial concentration of substrates.

The antimutagenic effects of juices and methanol extracts from cruciferous vegetables (cabbage, red cabbage, Korean cabbage, kale, cauliflower, broccoli, radish root, leafy radish, rape leaves and shepherd's purse) on the mutagenicity induced by aflatoxin B1(AFB1) and N-methyl-N'-nitrosoguanidine(MNNG) were studied using Salmonella assay system. In the case of juices from the cruciferous vegetables, the juices of cabbage, kale, cauliflower and radish root in the concentrations of 50, 200 and 500 ${mu}ell$/plate considerably decreased the mutagenicity induced by AFB1, and the juices of cabbage and broccoli in the concentrations of 200 and 500${mu}ell$/plate significantly reduced the mutagenicity induced by MNNG. The antimutagenic activities of the juices against AFB1 were stronger than those against MNNG. In the case of methanol extracts from the cruciferous vegetables, the methanol extracts of kale, broccoli and shepherd'purse appeared to inhibit the mutagenicity induced by AFB1 and MNNG in Salmonella typhimurium test strains. The effects of the juices against mutagens quite different from ones of the methanol extracts. The juice of cabbage showed antimutagenicity, but its methanol extract was less effective. However, both juices and methanol extracts from kale and broccoli exhibited strong antimutagenic activities against the mutagens.

The Tibetan Mastiff is one of the most archaic, ferocious and the largest dogs in the world. The Kunming dog is the chief working-dog breed in China. In this study, ten microsatellite loci were used to assess the genetic diversity and evolutionary relationships in six dog breeds, including Tibetan Mastiff, Kunming dog, Belgian Malinois, Labrador Retriever, English Springer Spaniel, and German Shepherd. The highest genetic diversity was exhibited by the Tibetan Mastiff, indicating useful protection and little inbreeding in the modern Tibetan Mastiff. Higher genetic diversity was observed in European breeds, supporting the hypotheses that breeders outcross their pure breed dogs occasionally to avoid deleterious effects in Europe. Evolutionary relationships showed that English Springer Spaniel and Labrador Retriever were clustered together, then with the Tibetan Mastiff, consistent with previous cluster results. German Shepherd and Kunming dog were grouped together, coinciding with the breeding history of Kunming dog. It is the first time that Tibetan Mastiff and Kunming dog have been analyzed with microsatellites.

Species like insects and fishes have, in many cases, non-overlapping time intervals of one generation and their descendant one. So the population dynamics of such species can be formulated as discrete models. In this paper various discrete population models are introduced in chronological order. The author's investigation starts with the Malthusian model suggested in 1798, and continues through Verhulst model(the discrete logistic model), Ricker model, the Beverton-Holt stock-recruitment model, Shep-herd model, Hassell model and Sigmoid type Beverton-Holt model. We discuss the mathematical and practical significance of each model and analyze its properties. Also the stability properties of stationary solutions of the models are studied analytically and illustratively using GSP, a computer software. The visual outputs generated by GSP are compared with the analytical stability results.
