A 6-month-old female Border Collie presented with a history of collapse after strenuous exercise. The dog was normal between episodes but experienced loss of focus and ataxia after exercise. This is particularly noticeable under hot weather conditions. No remarkable findings were observed in the diagnostic tests. Based on these results, the patient was tentatively diagnosed with Border Collie collapse (BCC). After exercise restriction, the dog had no episode of collapse and remained clinically well with no signs until the follow-up period of 8 months was complete. To our knowledge, this is the first case report of BCC in South Korea.

A 4-year-old, intact female Border Collie was presented for evaluation of hearing impairment. Clinical, neurological, otoscopic and magnetic resonance imaging examinations were carried out to determine the cause of hearing loss, but no remarkable change was found. Then, brainstem auditory-evoked response test was performed to assess hearing loss, and the dog had a bilateral sensorineural deafness was revealed. Since possible causes of acquired hearing loss were ruled out by several examinations and history taking, bilateral later-onset deafness was suspected to be genetic and not congenital. This report suggested the possibility that dogs had inherited later-onset sensorineural deafness.

A 2-year-old spayed female Border Collie presented with visual deficits and behavioral changes. Neurological examination revealed bilateral menace response deficit with a normal pupil light reflex. Cerebral cortical thinning, cerebral sulci and cerebellar fissure widening, ventriculomegaly, and cerebral atrophy were observed on magnetic resonance imaging (MRI). Histopathology revealed fluorescent lipopigment accumulation in the cerebrum, and the dog was diagnosed with neuronal ceroid lipofuscinosis. This is the first case report describing the changes in clinical signs, MRI findings, and histopathologic changes in neuronal ceroid lipofuscinosis in Korea.

A 3-year-old, 24-kg intact female Border Collie was referred for a toe-touch weight-bearing stance, intermittent weight-bearing lameness, and moderate pain reaction of the right forelimb on physical examination and right humerus olecranon avulsion fracture on diagnostic imaging examination. Surgical repair was performed using tension band wiring to re-attach the triceps tendon and distal olecranon. Migration of the distal olecranon fragment was observed due to comminuted fracture of the fragment 5-days after surgery, and revision surgery was performed. The tension-relieving sutures were passed through the pre-drilled hole in the olecranon, and the polyester mesh was augmented to the suture region, covering the triceps tendon and olecranon drilling hole using the Krackow suture pattern. The elbow joint was immobilized using a type IA transarticular external fixator, which was removed 8 weeks after surgery. Fourteen weeks after surgery, no lameness was observed on gait evaluation. At follow-up after 7 months, the distal olecranon fragment had stabilized, and no lameness was observed.

When a real robot manipulator is mathematically modeled. uncertainties are not avoidable. The uncertainties are often nonlinear and time-varying. The uncertain factors collie from imperfect knowledge ok system parameters. payload change. friction. external disturbance. and etc. In this paper. we propose a class of robust hybrid controls of manipulators without knowing the exact stiffness and provide the stability analysis. Simulation results are provided to show the effectiveness of the algorithms.

본 연구는 개 동결정액 희석액에 pentoxyfilline을 첨가하여 융해 후 정액성상에 미치는 영향을 조사하였다. 공시견은 2∼3세의 Beagle, English cockers spania, Collie, Grey hound, Shihtzu 5두를 공시하였다. 정액은 수압법 또는 인공질법으로 채취하였고 채취된 정액은 Rota 등(EYT : Egg-yolk Tris extender, 1995)의 방법에 따라 동결정액을 제조하였다. Pentoxyfilline은 동결 보호제가 들어 있는 2차 희석액에 0 mM, 1 mM, 3 mM 농도로 첨가하였으며, 5℃에서 2시간 glycerol 평형을 한 후에 액체질소에 10분간 예비 동결하여 동결정 액을 제조하였다. (중략)

An 8-month-old, intact male Collie and a 4-year-old, intact male Siberian husky presented with severe wounds on the limbs. Although the wounds were not managed adequately before presentation, there were no remarkable findings except for secondary infections. The lesions were cleaned with a disinfectant and then treated with systemic antibiotics. Additionally, a hydrophilic moisture-absorbing polyurethane dressing was applied to the limbs because a conventional bandage with silver sulfadiazine ointment was not effective. Both cases showed significant improvement in the lesions over a short period of time. These cases show that a bioactive dressing works efficiently to heal refractory wounds in dogs.

Background: Coal mining is a hazardous industry. The purpose of the study is to identify the nature of occupational injuries and diseases among coal miners and to determine the factors that affect the rate of injury and duration of time loss from work. Methods: A retrospective cohort study was conducted using accepted workers' compensation claims data of 30,390 Australian coal miners between July 2003 and June 2017. Results: Musculoskeletal and fracture conditions accounted for approximately 60% of claims in all occupational groups. Cox regression analysis showed that older age and female gender were significant predictors of longer time off work. Injury types and occupations were associated with work time loss: mental health conditions, and machine operators and drivers had significantly longer durations of time off work. Conclusion: Future research can further address how these factors led to longer time off work so that coal industry regulators, employers, and healthcare providers can target interventions more effectively to these at-risk workers.

Dimensional constants (k values) of single jersey fabrics made from $LincLITE^{(R)}$ and conventional yams are calculated under dry, steam, full relaxation treatments. Fabrics were made under different tightness factors such as high, medium and low with different twist factors, twist directions and feeder blending. $LincLITE^{(R)}$ yarns made to get soft and bulkier effects with yam count of 39 tex and conventional yams made into 39 tex and 48 tex yam counts. Various effects on K values are analysed using correlation coefficients. K-values are increased with relaxation progression and have shown some differences between in $LincLITE^{(R)}$ and conventional fabrics, and feeder blended fabrics. Loop shape factor is highly affected by tightness factor, relaxation and feeder blending in $LincLITE^{(R)}$ fabrics, whereas twist factor not significantly effects on loop shape factor in conventional fabrics. Stitch density significantly increases with relaxation in conventional fabrics and no significant effect shows with $LincLITE^{(R)}$ fabrics.
