The purpose of this research presents a method to position and makes the structure for eco-corridors reasonably with collectable analysing results of various effects shown in mammals' road-kill at 429 points. Target animals of this research are Leopard cat, Siberian weasel, Raccoon dog, Korean hare, Eurasian red squirrel, Siberian chipmunk and Water deer. The results derived from the empirical analysis on the contents above are followed. First, according to the results as for Leopard cat road kill analysis, which is designated as Endangered Species Class II, the eco-corridor might be located at near village having stead food in order to decrease the frequencies of road-kill, because its road kill points were mainly collected at 4 lane hilly road with mountain-road-farm area geological type of. Second, because Siberian weasel's road kill was detected at 2 lane hilly road with mountain-road-stream geological type, the eco-corridor might be located at near a mill to decrease road-kill frequencies. Third, the road-kill frequency of Eurasian red squirrel can be reduced when the eco-corridor is located at the area across coniferous tree near 4 lane west sea freeway with mountain-road-mountain. Fourth, the road-kill of Raccoon dog can be reduced when the eco-corridor is located at 4 lane mountain road or hilly road with the geological type having farm land-road-mountain(stream). Fifth, Korean hare's road-kill can be reduced when the eco-corridor is located at grass land across ridge line of mountain, because wild rabbit road kill was happened at 4 lane mountain road or 2 lane mountain road(mountain-road-mountain). Sixth, As for Siberian chipmunk, the eco-corridor might be located at the side slope of mountain road at 2 lane mountain road under the speed of 60km/h with mountain-road-mountain. Seventh, For Water deer, the eco-corridor might be located at 4 lane hilly road with mountain-road-farm land. As for Common otter, Amur hedgehog, Yellow-throated marten, Weasel, it is difficult to specify the proper site of eco-corridor due to the lack of data. Eco-corridors for carnivores might be well located at 4 lane hilly road or 2 lane hilly road with mountain-road-farm land, and the track for herbivores might be well located as a overhead bridge on mountain-road-mountain type across mountains. In order to position eco-corridors for wildlife properly, we have to research animal's behavior with ecological background, and to consider the local uniqueness and regularly collect the empirical road-kill data in long term 3 to 5 year, which can be the foundation for the more suitable place of wild life eco-corridors.

Along with the recent increase in national income, social phenomena such as aging due to a decrease in population and an increase in single households are observed. There are also an increasing number of households raising pets in proportion to aging households and the increase in the number of single households, most of which use animal companions to overcome loneliness and boost domestic vitality. As more and more people consider pets as family members, the size of the domestic pet market is also growing. The growing number of pets in older households and single households is not properly managed by care such as food meals and exercise management for pets. It is necessary to research and develop robots that can monitor animal companions remotely, feed a certain amount of food at regular intervals, and manage their health through exercise. Among pet companions, dog selection is the highest. Therefore, this study identified robot research on driving methods, examples of existing pet care systems, and researched pet care robots using obstacle avoidance algorithms. In order to use the snack pay behavior and obstacle avoidance algorithm of the pet animals by applying IoT and we .oPI technology, it is able to use ultrasonic sensors on the front and has four infrared sensors on the back. However, this study does not reflect the characteristics of other pet animals as a study on pet care robots, and it requires continuous observation and testing.

This research performed single fiber pull-out test to evaluate the effect between fineness modulus of cement composites and the fiber bond performance (bond strength and pull-out energy). A synthetic fiber (polypropylene) and a steel fiber (hooked ends type) were inserted in the middle of dog bone shape specimens which were designed with fine aggregates of F. M. 1.96, 2.69, 3.43. The experiment results showed bond strength and pullout energy of synthetic fiber are improved as fineness modulus of cement composites increases. It is considered that the frictional resistance between synthetic fiber and cement composite increases as fineness modulus of cement composite increases and consume more energy while pull out the fiber from cement composite. However bond performance of steel fiber which resist pull out by mechanical behavior is less effected on fineness modulus of cement composite. It is considered that the mechanical fixedness of hooked ends exerts a greater effect on the pullout resistance than the frictional resistance between the cement composite and the steel fiber so F. M. of fine aggregate has a relatively small effect on the pullout resistance with the steel fiber.

This study was performed to investigate non-invasive behavioral pain assessment of dogs after surgery, and the analgesic effects of butorphanol after intestinal anastomosis in dogs. In this study, five dogs in the Control Group were anesthetized, but did not undergo surgery. Five dogs in the Analgesic Group were undergone intestinal anastomosis and treated with butorphanol. Five dogs in the Non-analgesic Group were also undergone intestinal anastomosis without analgesic treatment. The dogs in the Analgesic Group received butorphanol (0.4 mg/kg, IM) before and immediately after operation, while dogs in Control and Non-analgesic Groups received isovolumetric doses of sterile saline. The behavior of dogs were videotaped for 400 mins after anesthesia, during which time a researcher interacted with the dog once per each 80 mins. At each interaction, the researcher recorded behavioral pain score, using University of Melbourne Pain Scale. Interactive and non-interactive behaviors were observed and quantitated by a single observer using focal continuous sampling method. Vocalizations were obtained during 400 mins after anesthesia, and duration of call, intensity, pitch, 1-4 Formant were analyzed. Surgery affected an increasing of pain score. During interactions with researcher, greeting behaviors were decreased after surgery. Differences between Analgesic group given analgesic or that given a placebo drug were readily understood using quantitative behavioral measurements and vocalization. Significant difference between Analgesic group given butorphanol or that the given placebo drug was apparent(p< 0.05).

This study was conducted to evaluate the clinical relevance and effectiveness of ovariectomy (OVE) and ovariohysterectomy (OVH) in terms of postoperative pain behavior and surgical stress. Thirteen healthy intact mongrel purpose-bred female dogs were used in this study. OVE was performed in six dogs whereas OVH was performed in seven dogs. Prior to, 1, 2, 4, 6, 12, and 24 h after surgery, pain assessment was performed by using the Short form of Composite Measure Pain Scale (CMPS-SF) and blood analysis for the determination of glucose, creatine kinase (CK), and cortisol were done. Also, surgical time, duration of anesthesia, and incision length were compared between two groups. As a result, OVH group as opposed to OVE group showed significantly longer in surgical time, duration of anesthesia, and incision length. Also, based on the two-way ANOVA test, the CMPS-SF had significant differences (p < 0.05) between two groups, with the OVE dogs having lower values at 1, 2, 4, and 6 h postoperatively. In addition, in terms of CK, the value at 1, 2, 4, 6, and 12 h were significantly (p < 0.05) increased from the baseline value for the OVH group. However, as for CK in OVE group, the values at 4, 6, and 12 h were significantly increased from the baseline value. As for blood glucose, a significant (p < 0.05) increase from the baseline was shown at 1 h postoperatively in OVH group and no significant increase was shown in OVE group. In terms of serum cortisol level, the values at the 1 and 2 h were significantly (p < 0.05) increased from the baseline value for both groups. In conclusion, our study has shown that OVE can be considered as a superior choice in terms of sterilization technique in female dogs, considering shorter incision length, surgical time, duration of anesthesia along with lower pain and surgical stress response than OVH.

As Korea is moving toward multicultural society, the number of Muslim, whose religion has a great influence on diet-related behaviors, is increasing in Korea. Since the number of immigrants from Indonesia ranks within top ten in Korea and Indonesia is one of the most representative Islamic countries in Asia, understanding the diet-related behaviors and food preferences of Indonesians is needed. This study was conducted to investigate diet-related behaviors, factors affecting the diet-related perceptions, and food preferences of the Indonesians. The subjects included 500 Indonesians dwelling in Jakarta, Indonesia. About ninety % of the subjects in this study were Muslims. They did not eat pork and dog meat for religious reason and they practiced fasting during Ramadan period. Indonesians avoided pineapple, durian, and hot foods during pregnancy and usually ate vegetables and fruits after birth, which seemed to be due to sociocultural influence. Among the subjects, 21.5% were obese and major health problems reported were hypertension and hyperlipidemia. Their preference for fried food items might have contributed to health problems. Subjects had meals mostly at home (2.3 times/day) and dined out occasionally (1.2 times/week) at Indonesian restaurants (56.6%) or family restaurants (21.0%). In conclusion, Indonesians had home-based and native food-oriented dietary life with strong religious and sociocultural influence on food choices. Further research on specific nutrient intake analysis is needed to better understand and to improve dietary life of Indonesians in Korea.

Generally, the vertical roll process is used to achieve extensive width reduction in hot strip mill. However, it is difficult to avoid the defects such as dog-bone and seam-defect. The sizing press has been developed in response to the defects mentioned above. Especially, this study is carried out to investigate the deformation of slab by two-step sizing press. The deformation behavior in the width sizing process is more favorable than that in conventional vertical rolling edger. The objective of this study is to determine the optimal anvil shape parameters in the sizing press with two-step die from the viewpoint of edge-seam length. In general, the edge-seam defect occurs parallel to the rolling direction at both edges in horizontal rolling process after sizing press. The optimal combination of the parameters is determined by FE-simulation and Artificial Neural Network (ANN). The slab deformation in sizing press with convex anvil is analyzed by FE-simulation. The most suitable profile of the anvil is also discussed fur the improvement of trimming loss because of the side seam defect by FE-simulation and ANN.

Purpose: For the health of pet dogs and to reduce harm to humans, we investigated the preference of pet dogs on cushions made from functional ocher textile, which is known to be beneficial to human health. Methods: The preference of 12 small dogs between cushions made using functional ocher textile and normal yellow colored fabrics was observed. Results: The observation study showed 83.3% preference on cushions made from functional ocher textile where dogs rested or slept mostly. The biting behavior was improved by 83.3%. After using the functional cushions, four dogs with eye disease, one with eczema, and two with allergy showed improvements while others showed no improvement. After the experience, 50% of dogs became quieter. 87.5% of dogs showed more mild temperament. Conclusions: The functional ocher cushions showed preferences by dogs as well as brought positive improvements with the temperament and health conditions. This study proves to be a valuable fundamental research in this field of functional ocher cushions.

This study was aimed to evaluate the effects of tramadol hydrochloride on the minimum alveolar concentration of isoflurane ($MAC_{ISO}$) in dogs. Six healthy, female German shepherd dogs (aged 1-2 years) were used in this study. Anesthesia was induced by mask induction and maintained with isoflurane in oxygen. Mechanical ventilation maintained the end-tidal $CO_2$ partial pressure ($P_{ET}CO_2$) from 35 to 45 mmHg throughout the study. A baseline $MAC_{ISO}$ ($MAC_{ISO}B$) was determined starting 45 minutes after induction of anesthesia by clamping a pedal digit until gross purposeful movement was detected. After $MAC_{ISO}B$ determination, dogs received a tramadol loading dose of 3 mg/kg followed by a continuous rate infusion (CRI) of 2.6 mg/kg/h. The determination of $MAC_{ISO}$ after administration of tramadol ($MAC_{ISO}T$) began 20 min after the start of the CRI. Arterial blood pressure and heart rate were recorded continuously and arterial blood samples for blood gas analysis were collected at the end of the equilibration period. Mean ${\pm}$ SD values for the $MAC_{ISO}B$ and $MAC_{ISO}T$ were $1.33{\pm}0.04%$ and $1.23{\pm}0.04%$, respectively. The $MAC_{ISO}B$ decreased significantly by $7.5{\pm}0.2%$ (P < 0.05) after administration of tramadol. The mean heart rate and arterial blood pressure of six dogs were not changed significantly after tramadol administration. The blood gas levels remained constant during the study. In conclusion, tramadol could significantly reduce $MAC_{ISO}$ without depression of cardiorespiratory function. Thus, the use of tramadol on inhalation anesthesia with isoflurane in dogs can improve the stability of anesthesia and the quality of recovery.

In recent years, there has been a growing interest in deep learning-based animal pose estimation, especially in the areas of animal behavior analysis and healthcare. However, existing animal pose estimation techniques do not perform well when body parts are occluded or not present. In particular, the occlusion of dog tail or ear might lead to a significant degradation of performance in pet behavior and emotion recognition. In this paper, to solve this intractable problem, we propose a simple yet novel framework for pet pose estimation where pet pose is predicted on an outpainted image where some body parts hidden outside the input image are reconstructed by the image inpainting network preceding the pose estimation network, and we performed a preliminary study to test the feasibility of the proposed approach. We assessed CE-GAN and BAT-Fill for image outpainting, and evaluated SimpleBaseline for pet pose estimation. Our experimental results show that pet pose estimation on outpainted images generated using BAT-Fill outperforms the existing methods of pose estimation on outpainting-less input image.
