목적: 난시가 존재하는 피검자들에게 원데이 프리즘 밸러스트 및 이중 슬랩오프 디자인 안정화 방법을 이용한 제품을 각각 착용하여 난시 정도에 따라 렌즈 회전량과 자각적 만족도를 비교해보고자 하였다. 방법: 난시가 존재하는 피검자(20~25세 사이) 63안을 모집하여 피검자의 실린더 값을 자/ 타각적 방식으로 측정하여 두 그룹(Low : C-0.75~C-2.00, High C-2.25~C-4.00)으로 분류하여 각각 A사의 ‘프리즘 밸러스트’ 방법으로 제작된 렌즈와 B사의 ‘이중 슬랩오프' 방법 으로 제작된 토릭 소프트렌즈를 번갈아 착용하였다. 사용된 렌즈의 B.C는 모두 8.5mm이 고, 함수율은 각각 56%, 59%였다. 그리고 사용된 소재는 'Silicone Hydrogel'이었다. 두 렌즈를 착용하고 30분 안정화 후에 정상 범위의 피팅에 포함되는 대상자를 기준으로 세극등을 사용하여 렌즈 회전량을 측정하고 피검자에게 설문조사를 실시하여 착용감, 만족도 등의 설문을 진행하였다. 결과: 두 그룹중 상대적으로 낮은 난시값을 가지고 있는 피검자군은 'Double Thin'으로 제작된 렌즈에서 평균 렌즈 회전량은 4.38±2.34°이었고, 평균 만족도 점수로는 10점 만점에 서 8.11±1.13점을 획득하였다. 'Prism Ballast'로 제작된 렌즈에서 평균 렌즈 회전량은 2.81±2.78°이었고, 평균 만족도는 8.67±0.87점을 획득하였다. 그리고 높은 난시 값을 가진 피검자군은 ‘Double thin'으로 제작된 렌즈에서 평균 렌즈 회전량은 3.44±3.26°이었고, 평균 만족도는 8.33±1.03점을 획득하였다. 그리고 'Prism Ballast'으로 제작된 렌즈에서 평균 렌즈 회전량은 6.56±4.13°이었고, 평균 만족도는 7.78±1.28점을 획득하였다. 결론: 상대적으로 낮은 난시 값을 가지고 있는 경우 'Prism Ballast'로 제작된 토릭 소프트 렌즈를 착용한 경우 'Double Thin' 렌즈를 착용하는 것보다 상대적으로 더 적은 렌즈 회전 량이 측정되었고, 반대로 상대적으로 높은 난시 값을 가지고 있는 피검자들은 ‘Double Thin’ 렌즈를 착용하는 것이 ‘Prism Ballast’렌즈를 착용하는 것보다 상대적으로 더 적은 렌즈 회전량이 측정되었다. 따라서 난시 값의 정도에 따라 두 안정화 디자인에서 회전량은 서로 차이가 있는 것으로 사료된다.

Customers are generally requiring a variety of products, earlier due date, and lower price. A manufacturing process needs the efficient scheduling to meet those customer's requirements. This study proposes the novel algorithm named MJA(Minimum Job completion time and AGV time) that increases the performance of machines and AGV(Automated Guided Vehicles) in many kinds of job types. MJA optimizes the bottleneck of machines and efficiency of AGV with considering two types of dispatching at the same time. Suggested algorithm was compared with existing heuristic methods by several simulations, it performed better for reducing the time of tardiness.

A 14-year-old intact female, mixed dog was presented with hematuria and strangury. Mass in the abdominal cavity was seen on radiographs and ultrasound. On the cytological examination in the urethra, clusters of pleomorphic epithelial cell were found. Tissues of the urethra and the urinary bladder were obtained at the time laparotomy and determined the extent of the mass. Transitional cell carcinoma (TCC) of the urinary bladder was found in histopathologic characteristics. Urinary diversion after removal of a complete full section of the TCC in bladder wall was performed. Piroxicam, as a medical therapy for TCC, was orally administrated. Surgical operation and chemotherapy were selected with the goal of maintaining and improving quality of life.

Immunohistochemical localization of vimentin, glial fibrillary acidic protein (GFAP), myelin basic protein (MBP), neuron-specific enolase (NSE) were performed to confirm the canine schwannoma diagnosed histologically. Biopsy samples from skin masses occurred on a 6 year old female dog and a 13 year old female dog were used for immunohistochemical analysis. Histologically, the tumor tissues showed the characteristics of schwannoma mainly composed of predominantly fusiform or spindle cells. The cells are arranged in small interwoven bundles with intervening fibrous and mucinous stroma that imitate a herringbone pattern. The cell nuclei have an elongated, wavy, buckled appearnce and closely bunched together. In high magnification, mitotic figure, nuclear hyperchromatism, pleomorphism and poorly defined cytoplasms were noted. the vimentin was highly expressed in the cytoplasm of all neoplastic cells. Positive reactions against NSE and GFAP, widely used to suggest a neural origin of cell types, are observed in cytoplasms of tumor cells. These results can be used as a reference data for definitive diagnosis of canine schwannoma.

This study investigated the frequency and distribution of canine patellar luxation (PL) in Bucheon city during January 2003 to December 2006. The 144 dogs with PL were analyzed according to grade, breeds, sex, age, body weight, and existence of concurrent cranial cruciate ligament rupture. Small breed including Yorkshire Terrier (31.65%), Maltese (33.09%) and Poodle (12.23%) had higher distribution of PL. Especially Yorkshire Terrier and Maltese had higher population of PL compared with other breeds. Most of them were diagnosed as II-III grade PL, and only a few dogs had grade I and grade IV PL. Small breed of body weight 2-3 kg (38.88%) had higher population of PL, and most of them were intact female (46.52%) and castrated male (38.19%) dogs. This study showed that clients recognized the necessity of the operation for dogs with PL well when the dogs are 6 months and 3 year-old, and have II-III grade PL. The reason that body weight of 2-3 kg had higher percentage of PL is related to the breeds. In analysis, intact female and castrated male dog had higher distribution of PL. The occurrence of concomitant cranial cruciate ligament rupture was 11%. Patellar luxation is therefore considered having an influence on cranial cruciate ligament rupture.

A two-month-old male calf weighing 70 kg with congenital metacarpophalangeal flexural deformity was referred to the Veterinary Medical Center of Chugbuk National University. The calf could not stand and walk normally that walked with the dorsal surface of the hoof with contraction of fetlock joint. The both forelimbs had been casted two times during 45 days before presentation. Midline of the palmar surface of the feltlock joint was incised to cut superficial flexor tendon, deep flexor tendon and interosseus muscle. Both forelimbs are healed well returned to normal function after tenotomy.
