  • The purpose of this research is to investigate how an elementary English class is presented in terms of communicative properties using COLT and TALOS because previous studies mainly used COLT. A lack of TALOS has shown on the previous studies. Also, this study takes a close look into whether the English class is communicative or not communicative since previous studies criticized in that elementary English classes are not communicative. For the purposes of this research, COLT part B and TALOS low-inference were used to analyze one elementary English class which had won the grand prize at English class contest. The result of this study revealed that the class is communicative in terms of high quantity and quality of students utterances, high ratio of students' discourse initiation, students' unpredictable information giving utterances and extension of utterances. Findings from this study revealed the good elementary English class characteristics of this class: students' participation, focus on affective atmosphere, students-directed activities, and unconscious internalization of target expressions through repetition.

  • The purpose of this paper is to investigate how the English classes in secondary schools in Korea are in terms of communicative nature. After literature study, COLT parts A and B were used to analyze three kinds of English classes: a common class type taught by a school teacher who had won 1st prize at TEE contest, a team teaching class taught by NNS and NS, and a model class taught by a pre-service English teacher. Their communicative English classes were videotaped and transcribed for analysis by COLT. The results of the study revealed that students participated in the classes mostly as a unit and, therefore, did not get many meaningful chances to speak English. Second, creative language-use opportunities were barely found during classes. Third, the group work seemed to be prepared before the class, not to be done during the class. Therefore it is likely to be learned from memorization rather than meaningful communication. These results suggest English classes in schools be more communicatively oriented for successful English learning. Further study should be conducted in order to make English classes more communicative to help students communicate their genuine messages in English and to help teachers teach English efficiently.

  • The present study was conducted to determine the optimum in vitro conditions for callus induction and plant regeneration from mature seed derived callus of four cultivars of Timothy. In order to investigate the effects of genetic variations of timothy in tissue culture, calli were induced from mature seeds of four varieties, 'Colt', 'Chair', 'Richmond' and 'Hokuo' and plant regeneration frequency was compared. Significant differences were observed among the cultivars in both callus induction and plant regeneration. Genotype 'Colt' consistently performed best in the callus subculture and plant regeneration. The complete plantlets were thereafter transplanted to grow under greenhouse condition. Regenerated timothy plants were morphologically uniform with normal leaf and growth pattern.

  • A 3-year-old black Thoroughbred colt weighing 500 kg was admitted to the Equine Hospital of Korea Racing Authority (KRA) due to the chronic gait abnormality of the hindlimbs. The history revealed that the patient had run and fallen onto the fence of the farm about at the age of 1 year old and the lameness had been worsening insidiously since the accident. The degree of lameness was 2/5 in accordance with the AAEP lameness grading system in both hindlimbs at hand walking and trot. The lameness was exacerbated at lunging clockwise and counterclockwise on both hindlimbs. The definitive diagnosis of the bilateral osteoarthritis of coxofemoral joint was established using radiography under general inhalation anesthesia. The prognosis was considered to be poor with low expectancy for racing and the colt was expelled from the racecourse eventually. The clinicians are required to consider the possibility of osteoarthritis of coxofemoral joint presented with chronic hindlimb lameness although it is rare. This is the first report on the bilateral osteoarthritis coxofemoral joint in Republic of Korea.

  • A 14-month-old Thoroughbred colt with hind limbs lameness was referred to Equine Hospital of Jeju National University. During physical examination, the patient could not walk in a straight line but wobbled especially with hind limbs. He hesitated when backing and crossed hind limbs while circling tightly by protracting the outer hind limb keeping the inner hind limb stationed. Stenosis was observed between the 2nd (C2) and 3rd (C3), and the C3 and 4th (C4) cervical vertebrae on radiographs. The colt diagnosed as cervical stenotic myelopathy (CSM) based on the clinical signs and radiological findings. To confirm the diagnosis, postmortem computed tomography (CT) and histopathologic examination were performed after the euthanasia. The CT images revealed severe compression of the spinal cavity and cord between C3 and C4 cervical vertebrae. Grossly, there was compression of the spinal cord between the C3 and C4 cervical vertebrae. Histopathologically, severe axonal swelling and demyelination characterized by vacuolation and cavity formation were observed in the white matter of the spinal cord, especially in C3 and C4. CSM is problematic in the horse racing industry because of abnormal walking. This case report of CSM may offer information for diagnosis of the disease in the equine veterinary fields in the Republic of Korea.

  • A one-month-old Thoroughbred colt presented with left hindlimb lameness grade 5/5, according to the American Association of Equine Practitioners' lameness scale. The colt started showing signs of lameness two weeks earlier without being involved in an accident. A local veterinarian examined the foal; radiography revealed no significant findings under the hip joint. No improvement was noted after 15 days of non-steroidal anti-inflammatory drugs (NSAIDs) medication. On presentation at our hospital, ultrasonography was performed, which revealed no significant findings in the iliac wings. The foal underwent a computed tomography (CT) scan under general anesthesia. CT revealed bone cysts in the following that could have caused the lameness: the left transverse process of the 5th, 6th lumbar, and the 1st sacrum vertebrae; osteophytes in the auricular surface of the ilium, suggestive of sacroiliac arthritis. The foal recovered smoothly from anesthesia with assistance. The foal was treated with NSAIDs and rested for more than six months. The owner reported that the foal showed no lameness one year later. CT revealed bony changes in the lumbosacral region that were not detected by radiography and ultrasonography, suggesting that CT could be useful for detecting abnormalities in the pelvic region of horses.

  • The welfare of horses depends on satisfying both the physiological and psychological needs of the animal. The object of this study was to evaluate fence safety at the horse farm. A Thoroughbred colt with cribbing was found dead in a paddock. The fence of paddock is a four-pipe fencing. He cribbed the 2nd pipe from the top. But he couldn't pull his face because his incisors acted as hooks and two ramuses of the mandible was entrapped in a top pipe. So he was embarrassed and went down while he terribly struggled to get out his face. Finally, he was strangulated to death. Safe fencing is essential on a horse farm. The function of these fences are to protect the horses but it was more of a hazard. In order to safe management of horses, facial length of the horse and the pipe interval of the fence should be considered. Further research is needed to put a muzzle on the horses while they are at a paddock. This study provides important benchmarks for the equine industry to consider fence type and evaluate fence safety.

  • We need the contingency cost in order to deal with the uncertainty to be accompanied inevitably at the construction and an every kind risk not to forecast in advance. And also the contingency colt needed for the change order and we need it for reduction of the delay and reduce the trouble between owner and constructor. This study, through checking and analyzing the risk factor, in the step of domestic construction, suggests optimal management reserve to specific business about the contract type and the scale. The main results of this research are summarized as follow. First, I investigated the recognition about the contingency cost, grasped the risk to be happened at the construction step and found out the frequency occurrence, through making up question to engineer are carrying out their job in the domestic construction. Second, I computed optimal contingency cost rate by the statistics investigation, and proposed an improvement plan and problem when compute a contingency cost.
