Recently, several ICT-based cat studies have produced some successful results, according to academic and industry sources. However, research on the level of simply identifying the cat's condition, such as the behavior and sound classification of cats based on images and sound signals, has yet to be found. In this paper, based on the veterinary scientific knowledge of cats, a practical and academic cat monitoring and disease diagnosis system is proposed to monitor the health status of the cat 24 hours a day by automatically categorizing and analyzing the behavior of the cat with location information using LSTM with a beacon sensor and a raspberry pie that can be built at low cost. Validity of the proposed system is verified through experimentation with cats in actual custody (the accuracy of the cat behavior classification and location identification was 96.3% and 92.7% on average, respectively). Furthermore, a rule-based disease analysis system based on the veterinary knowledge was designed and implemented so that owners can check whether or not the cats have diseases at home (or can be used as an auxiliary tool for diagnosis by a pet veterinarian).

This study investigated the effect of Bacillus subtilis (B. subtilis) natto on meat quality and skatole in TOPIGS pigs. Sixty TOPIGS pigs were randomly assigned to 3 groups (including 5 pens per group, with 4 pigs in each pen) and fed with basic diet (control group), basic diet plus 0.1% B. subtilis natto (B group), and basic diet plus 0.1% B. subtilis natto plus 0.1% B. coagulans (BB group), respectively. All pigs were sacrificed at 100 kg. Growth performance, meat quality, serum parameters and oxidation status in the three groups were assessed and compared. Most parameters regarding growth performance and meat quality were not significantly different among the three groups. However, compared with the control group, meat $pH_{24}$, fat and feces skatole and the content of Escherichia coli (E. Coli), Clostridium, $NH_3$-N were significantly reduced in the B and BB groups, while serum total cholesterol, high density lipoprotein, the levels of liver P450, CYP2A6, and CYP2E1, total antioxidant capability (T-AOC) and glutathione peroxidase and Lactobacilli in feces were significantly increased in the B and BB groups. Further, the combined supplementation of B. subtilis natto and B. coagulans showed more significant effects on the parameters above compared with B. subtilis, and Clostridium, and $NH_3$-N. Our results indicate that the supplementation of pig feed with B. subtilis natto significantly improves meat quality and flavor, while its combination with B. coagulans enhanced these effects.

Objectives : Doctors are obviously one of the most interesting subject in medical history. Doctors are who treat patients and disease and the authors for medical records or books. Especially doctors in traditional medicine mostly tried to write medical books for new idea or their esperiences or leave their medical records for treatments, medication, prescription and so on. Therefore, many researchers have explained Korean or Chinese medical history of traditional society through those books or documents rather than doctors themselves. The Annals of the Joseon Dynasty has massive records for history, politics, society, culture, etc. Relating to medical history in traditional Korean medicine, there are ceveral researches about disease of King, disease itself, the methods of treatment and so on, through The Annals of the Joseon Dynasty. However, there are few on activities of many doctors in The Annals of the Joseon Dynasty. Methods : I tried to find out the names who had some roles of medicine in The Annals of King Sejong out of The Annals of the Joseon Dynasty. I could get 35 doctors and browsed 35 doctors in The Annals of the Joseon Dynasty again. Finally, I could have lots of articles from The Annals of the Joseon Dynasty related to 33 doctors(2 dontors had no records about medicine even they were doctors). Results : I categorized 2 ways of those articles; medical activities, non-medical activities. For medical activities, I got subcategories for medical activities; medical maltreatment, treatment for King, royal family, bureaucrat, ambassador. I also got subcategories for non-medical activities; publishing medical books, ambassador as a doctor, medical training, things related to hot spring, food therapist, veterinarian. Conclusions : Medical history of Joseon Dynasty in Korean medical history has somehow been recorded by medical books such as Hyangyakjipseongbang, Euibangyuchwi, Euilimchwalyo, Dongeuibogam, Jejungsinpyeon, Dongeuisusebowon, etc. So I have concerned that there are massive records on doctors activities in The Annals of the Joseon Dynasty and tried to focus on their various activities through this research.

As with humans, overweight or obesity is a major health concern in the companion animal population. A cross-sectional questionnaire-based survey of dog owners attending primary small animal veterinary practices from different areas in Chuncheon, Kangwon province, Korea was undertaken to explore the relationships between socioeconomic and other relevant risk factors associated with canine obesity. In addition, the author was to estimate the prevalence of obesity compared to published literatures for dogs. Owners were asked about dog age, neuter status, feeding habits, dog exercise, household income and owner age. The body condition score (BCS) of the dogs was also assessed. Multivariable binary logistic regression was used to assess the association between BCS and potential risk factors controlling for confounding variables, using odds ratios (OR), 95% confidence intervals (CIs). A total of 275 dogs (136 males and 139 females) aged 1-12 years (mean age $5.6{\pm}3.7$ years) were surveyed in 2013. Of these, 46.9% of dogs (n = 129) were classed as an ideal body shape (BCS = 3), 30.9% (n = 85) were overweight (BCS = 4), 8.4% (n = 23) were obese (BCS = 5) and 13.8% (n = 38) were underweight (BCS = 1 or 2). Neutered males and spayed females had the highest prevalence of obesity (43.4% and 33.9%); intact females had the lowest prevalence of obesity (31.6%). In univariable model, risk factors associated with canine obesity are multifactorial and include owner income, owner age, age of dog, neuter status, frequency of feeding per day, frequency of snacks and consultation with veterinarian on dog's weight. In final multivariable logistic regression model, dogs whose owners reported no consultation with veterinarians for weight management were significantly more likely to be obesity than ideal (OR = 7.6, 95% CI, 4.2-13.8; p < 0.0001). This study showed a high prevalence of obesity in domestic companion dogs. Since this was a cross-sectional study with small samples, the association of canine obesity with risk factors warrants more research. To the author's best knowledge, this is the first Korean study on dog body condition and obesity.

The objective of this study was to evaluate the duration of retained placenta (RP) on postpartum diseases and culling in dairy cows. Data were collected from 456 Holstein cows between 2008 and 2010. RP (${\geq}$ 24 h after parturition) and postpartum diseases were diagnosed by farm managers and a veterinarian according to standardized definitions. The overall incidence rate of RP was 14.0%, and the incidence rate of RP with fourth and higher parity was two times that of cows having offspring for the first time. The duration of RP was 2 to 15 days with a mean of 6.8 days, except for cases of fourth and higher parity which had a mean of 10.5 days. A total of 63% of cows with RP had postpartum diseases. Among the cows diagnosed with RP, 23.4% developed metritis, and of those, 35.3% developed endometritis or pyometra. A total of 25% (n = 16) cows with RP were culled within 60 days in milk (DIM) and of those culled, 75% (n = 12) had postpartum diseases. These results suggest that RP increases the risk of postpartum diseases such as metritis and mastitis and is a culling hazard up to 60 DIM.

A female Green iguana (Iguana iguana) was brought to the small animal clinic in Hannover Veterinary school because of anorexia and convulsion. Two months ago, the owner bought two iguanas, one female and one male and had to take a female to the one of local small animal clinic because she, born in 19931 didn't eat well and showed the tremor of the legs. The veterinarian suspected it to have a calcium deficiency and gave an injection of calcium and vitamin D3. But still during the last two months, the female iguana did only eat some lettuce while the other male ate lettuce, fruits and commercial cat-food ($Whiskas^{\circledR}$, Effem, Verden). It was not possible to evaluate the rations of these different "food-components". They are kept in the terrarium with water container. By palpation of the abdomen, hard thing like stone was palpated in the mid-region. The blood test wasn't carried out because of the difficulties of getting blood and because of her bad condition. It was firmly diagnosed as cystic calculus through radiography. Since the animal is in shock state already, the prognosis after surgery was bad. It was assumed to be too late to expect its surviving with the surgery carried out or without it. Cystotomy was performed in the cranial ventral paramedian incision in order to preserve the large ventral abdominal vein in the linen alba region. After two stay sutures ("holding suture" ) with 5-0 polyglactin 910 ($Vicryl^{\circledR}, Ethicon$) on the bladder, cystotomy was carried out and the stone inside was removed. Then, the bladder was closed in one-layer sutures. The abdomen was closed in simple interrupted suture with same material after the instillation of 10 ml saline solution into the abdominal cavity. The cystic calculus was in a size of $5.8{\times} 5.O{\times} 3.5 cm$. The analysis of the stone was carried out in two ways which are the infrared spectroscopy of the stone and quick analysis by $Merckognost^{\circledR}$(Diagnostica Merck, Merck). In the result of the infrared spectroscopy, the stone wee composed of 10% ammonium urate and 90% dihydrated uric acid. This iguana wasn't able to survive.n't able to survive.

This work described 3 infection cases caused by Rhodococcus equi in foals between 3 and 5 months of age. The disease histories were not fully taken from local veterinarians. At least 1 sick foal has been treated with cephalothins followed by penicillins during approximately 1 week, but died without effectiveness and other foals rearing with the animal have been suffering from severe pneumonia which show high fever, laboring respiration, cough and/or nasal discharge. There were many abscessations into lungs of 2 foals in postmortem examination and another 1 sample was pus collected from abscess around the shoulder, indicating the osteomyelitis. Those bacteria were grampositive coryneform and were identified as a R. equi by a polymerase chain reaction (PCR) using primers for R. equi-specific vapA gene. The pathogens were usually resistant to penicillin, ampicillin, amoxycillin/clavulanic acid, cefazolin, clindamycin, sulfamethoxazol/trimethoprim, kanamycin, and tetracycline, while were sensitive to ciprofloxacin, norfloxacin, orfloxacin, gentamicin, erythromycin, neomycin, and vancomycin. Some more foals with respiratory symptoms in 1 horse farm were treated by orally administration with erythromycin during 2 weeks. Because the combination of erythromycin and rifampin has recommended as the treatment for R. equi infections in foals, the local equine veterinarian can choose those antibiotics for the treatment of this disease in future. However, another antimicrobial agent may be necessary if R. equi resistant to both agents is isolated.

Epizootiolosical factors of 166 cows with abomasal displacement were studied and in 21 out of 166 cows, the functions of liver and kidney were also tested. 1. Incidence of abomasal displacement was perdominant in small sized dairy herd less than 15 cows, using area of paddock below 165㎡. 2. Out of 166 cows with abomasal displacement, 116 cows (70%) were found left sided displacement and 50 cows (30%) were right. 3. Generally, one to two weeks were taken before treatment of veterinarian following onset of sign of the diseases. Therefore many cases were found to be severe in their illness. 4, Incidence rate of abomasal displacement was predominant in summer season (June, July and Au-gust). However, occurence of the disease was continuous throughout the year. About 80 percent of abomasal displacement was distributed from first to third purturition. 5. High milk production and feeding with high concentrates and low roughage showed a tendendy to occurs the disease. 6. Approximately 75% of abomasal displacement was distributed within 1 month pre and post partum. 7. Cows with abomasal displacement consumed little concetrates and 75% of cows with abomasal displacement passed abnormal fecal material. 8. Sixty six out of 166 cows with abomsal displacement were coincident with diseases such as retained placenta, metritis, traumatic reticulo-peritonitis and mastitis. 9. In many cass of abomasal displacement, abomasum was extended with gas. 10. Activities of AST ana LDH showed the trends to reduce after surgical intervention comparing with pre-surgery. Bilirubin concentration markedly decreased after surgical treatment comparing with pre-surgery. 11. The concentration of BUN and creatinine moderatly decreased after surgery compared with pre-surgery.

Discospondylitis is an infection of intervertebral discs, associated end plates, and adjacent vertebral bodies causing destruction and proliferation. A 10-year-old intact female Rhodesian Ridgeback dog was referred to the Veterinary Medical Teaching Hospital, Seoul National University with paraparesis and severe pain at T13-L1 region for one week duration. The treatment with PDS for one week by referring veterinarian showed no clinical improvement. At time of presentation, clinical signs of the patient included depression, vaginal discharge, and fever. In T-L spine radiography, osteolytic change was found between caudal endplate of T13 and cranial endplate of L1. The affected vertebral bodies were shortened and intervertebral disc space was widened. In abdominal radiography, a dilated soft tissue opacity tubular structure was found in mid-caudal abdomen. The abdominal ultrasonography revealed the uterus dilated with echogenic fluid. The CT findings showed concentric lysis of T13-L1 endplates. The dog was diagnosed as diskospondylitis at T13-L1 and pyometra. Urine and blood were cultured, and Staphylococcus (S.) intermedius was identified. The patient had surgical treatment for pyometra but died for septicemia.

우리 사람들은 자신의 생각을 다른 사람들에게 전하고자 할 때 언어를 주로 이용하고 보조적인 수단으로 몸짓을 한다. 사용하는 언어가 달라 소통이 어려울 때는 부득이 몸짓으로만 서로 의견을 나누게 되는데 손짓과 발짓은 물론 얼굴의 표정까지 동원된다. 물론 언어를 이용한 의사전달 만큼 정확하지도 못하고 시간적으로도 효율적이지 못하지만 그런 대로 급한 문제는 해결할 수 있는 경우가 않다. 동물들이 서로의 의사소통을 위하여 어떤 형태의 언어 및 언어에 가까운 음성기호를 이용할 능력이 있는지에 대하여는 학자들 간에도 논란이 계속되고 있으나 분명한 것은 어떤 방법으로든 동물들도 제나름대로 자신의 의사를 전달하고 또한 상대편이 전하고자 하는 뜻을 파악하여 이에 적절히 대처를 한다는 점이다. 이런 점에서 동물들을 대상으로 하는 학문인 수의분야에서는 우리 인간들에게 익숙한 언어와 행동이 아닌 동물들의 독특한 의사전달 방법을 정확히 이해하는 것이 무엇보다도 중요하다는 점을 인식하는 것이 필요하다 동물의 행동 하나 하나는 인간의 행동과 마찬가지로 나름대로의 의미를 지니고 있다. 이러한 동물의 행동을 인간의 눈 높이에서가 아닌 동물이 표현하고자 하는 행동 언어적인 측면에서의 이해가 필요한 것이다. 야생동물의 행동양식에 대한 연구는 생래학적으로 비교적 많이 이루어진 편이나 가축화된 동물들에 대하여는 체계적이고 비교학적인 연구가 아직도 부족한 실정이다. 특히 우리 나라에서는 이 분야에 대한 연구는 물론 외국의 연구내용에 대하여도 적극적인 소개가 이루어지지 못하였고 아울러 여러 분야에 실제 적용은 더욱 어려웠다. 동물의 건강을 책임지고 있는 우리 수의 분야는 물론, 가축을 사양하는 축산학 분야 및 모든 동물관련 분야에서 효율적이고 바람직한 동물과 인간의 관계를 구축하기 위하여는 무엇보다도 동물의 행동을 인간의 언어사용 측면에서 이해하려는 노력이 필요하다 하겠다. 이러한 일차적인 필요성에 조금이나마 도움이 되고자 하는 바람으로 외국문헌을 중심으로 인간의 생활과 밀접한 관계를 지닌 여러 동물들의 행동과 그 의미를 소개하고자 한다. 아울러, 소개되는 내용은 Domestic Animal Behavior for Veterinarians and Animal Scientists (제3판, Katherine A. Houpt 지음), Animal Behavior (Tim Halliday 지음), Canine and Feline Behavior Problems(Stefanie Schwartz 지음), Journal of Conpendium on Continuing Education for the Practicing Veterinarian,그리고The Merck Veterinary Manual의 Behavior와 같은 참고문헌에 크게 의존하여 기술된 것임을 밝힌다.
