This paper presents a high-fidelity simulation of the Organization for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) 3D whole-core Watts Bar benchmark using the UNIST in-house STREAM3D (Steady State and Transient Reactor Analysis code with Method of Characteristics) neutronic code. The benchmark encompasses various whole-core exercises, including single physics problems, multiphysics simulations, and depletion problems. When comparing parameters during the zero-power physics tests, including ITC, DBW, CRW, and criticality tests, STREAM3D results indicate a strong agreement with the measured data and KENO-VI. The comparison with the MC21/CTF code in 3D HFP BOC condition demonstrated strong agreement, with only a 0.42% difference in the normalized radial power distribution, a 0.38 K difference in the RMS of the assembly coolant exit temperature, and a mere 4 ppm difference in CBC.

Objective : This study was aimed to validate the Herbal Acupuncture Therapies(HAT) for cancer patients. Patients and methods : This retrospective study was performed on 8 patients who were diagnosed as cancer in Korea and treated with HAT in the oriental hospital of Daejeon University, from January 2003 to January 2004. We retrospectively analyzed the medical records of 8 patients for improvement of symptoms, toxic effects of liver and kidney, myelosupression and changes of Quality of Life(QOL). Results : Analysis of change of chief complaints showed that 75% patients replied moderate relief and 25% replied complete relief in Likert scale. Analysis of Liver Function Test(LFT), Renal Function Test(RFT) level showed that HAT does not have toxic effects on liver and kidney. Analysis of Complete Blood Count(CBC) level showed that HAT does not have myelosuppression effects on bone marrow. Analysis of QOL showed that 100% patients replied improvement in Eastern Cooperative Oncology Group status(ECOG) status. Conclusion : Our findings suggest that HAT offer potential benefits for cancer patients.

Pine needle oil and Korean medicinal herbs (KMH) are known as effective therapeutic agents on various blood vessel disease. We have already reported the ameliorative effect of complex of pine needle oil and Korean medicinal herbs against hyperlipidemia. But safety and non - toxicity of pine needle oil and Korean medicinal herbs to normal animal cells have not been studied clearly. In this study, we investigated whether pine needle oil and Korean medicinal herbs show side effects on rat or not. These materials were administered to rats, and subacute toxicity was examined by measuring the hematological values, CBC differentiation, biochemical levels of blood (TP, total protein; albumin; ALP, alkaline phosphotase; AST, aspatate aminotrans- ferase; ALT, alanine aminotransferase; T-Chol., total cholesterol; T-Bil., total bilirubin) and urine analysis, suggesting that the sample have no side effects and cytotoxicity. These results indicate that the complex of pine needle oil and Korean medicinal herbs may effective non- toxic, safety therapeutic agents on hepatocytes and hyperlipidemia.

Two bitches were presented to the Teaching Animal Hospital, Chonbuk National University with vagina prolapse along with prolapse of the bladder. Case 1 was a 2 years old, 38.5 kg, female Tosa dog which had slight shock and depression. She had a labor pain vagina prolapse since last 3 days. Case 2 was a 2 years old, 25 kg, female Rottweiler dog which was presented with the similar clinical signs with case 1. In both the dogs we performed plain radiography, CBC, blood chemistry and urine analysis. In case 1, we performed cesarean section along with the repositioning the vagina and the bladder. We found 13 fetuses among which 7 were alive. In case 2, we also performed cesarean section and recovered the fetuses. There were 7 fetuses but only one was alive. Among the 6 dead fetuses 3 were congenitally deformed. Then we reduced prolapsed vagina and bladder, and repositioned them. After that we performed ovariohysterectomy. Both the bitches become recovered from the prolapse of the vagina and bladder and there was no recurrence of the condition.

Knowledge of airflow characteristics in nasal cavity is essential to understand the physiological and pathological aspects of nasal breathing. Several studies have utilized physical models of the healthy nasal cavity to investigate the relationship between nasal anatomy and airflow. Since the final goal of these works is their contribution to the diagnosisand treatment of nasal diseases, the next step on this topic is naturally studies for disordered nasal cavities. In this paper, as the first application, airflows in the normal and abnormal nasal cavities with adenoid vegetation are investigated experimentally by PIV, and comparisons of both cases are appreciated. Dense CT data and careful treatment of model surface under the ENT doctor's advice provide more sophisticatedcavity model. The CBC PIV algorithm with window offset is used for PIV flow analysis. Average and RMS distributions are obtained for inspirational and expirational nasal airflows. Airflow characteristics that are related with the abnormalities in nasal cavity are presented.

This retrospective study was performed in 40 cases of canine crystalluria and urinary tract symptoms. Breed, age, sex, diet history and common clinical signs were investigated for patient information. CBC, serum chemistry, urinalysis, urine culture, urine sediment and urinary stone analysis were undertaken for clinicopathological diagnosis. Crystalluria and urinary tract symptoms occurred from 6 months till 14 years in this clinical investigation and the average age was 4.68 years. It had taken an average 7.4 weeks to correct crystalluria and urinary tract symptoms treated by supportive therapy and dietary management. In conclusion, regular clinical pathologic examination, treatment and diet management should be needed to prevent the formation of urolithiasis and urinary tract diseases in dogs with crystalluria and urinary tract symptoms.

Several studies have utilized physical models of the healthy nasal cavity to investigate the relationship between nasal anatomy and airflow. With our experiences of experimental investigations on nasal airflows in normal and abnormal nasal cavity models, we are going to deal with the topic that may contribute to the diagnosis and treatment of nasal diseases. In this paper, airflows in the normal and artificially deformed models, which simulate surgical treatment, are investigated experimentally by PIV. High-resolution CT data and careful surface rendering of computational model with the help of the ENT doctor provide more sophisticated nasal cavity models. The CBC PIV (Correlation Based Correction PIV) algorithm with window offset is used for PIV flow analysis. Average and RMS distributions in sagittal and coronal sections are obtained for inspiratory and expiratory nasal airflows. Comparisons in nasal airflows for both normal and deformed cases are also appreciated. In case of simulations of surgical operations, velocity and RMS distributions in coronal section changes locally, this may cause some difficulties in physiologic functions of noses and may hurt mucosal surface.

본 논문은 지금까지 이동망에서 제공된 단문 서비스 외에 특정 지역에 특정 정보를 전송할 수 있는 CBS에 대해 살펴본다. CBS는 단대단(end-to-end) 형태로 서비스 즉, 컨텐츠를 다른 사용자에게 제공하는 것이 아니라 특정 서비스 제공자(contents provider)가 사용자에게 광고나 중요한 정보들을 제공하는 방식으로, 단순한 서비스 제공뿐만 아니라 연관된 서비스들을 재창출할 수 있는 장점이 있다. CBS는 3GPP에서 제안한 SABP를 기반으로 관련된 연구개발이 이루어지고 있으며, 현재 핵심망과 관련된 CBC의 기능이 개발되어 프로토타입 형태의 연구가 이루어지고 있다. 향후 CBS 서비스의 성공 여부는 무엇보다도 CBS에서 제공할 서비스의 적절한 분류와 양질의 컨텐츠 제공에 달려 있다고 판단되며, 이와 더불어 서비스 제공자에게 사용이 편리한 이용 환경들을 제공할 수 있도록 시스템과 서비스가 개발되어야 할 것이다.

A female, 14-year-old mixed dog weighing 4 kg and a female,8-year-old schnauzer dog weighing 6 kg showing vaginal discharges and vomiting for a few weeks were examined for the preoperative check of anterior cruciate ligament rupture and the recheck after the surgery of nephrectomy. There were no distinct abnormal signs except for the increased CBC at schnauzer dog on blood chemistry analysis. Radiographic and ultrasonographic findings were a large abdominal mass and a cyst-like hypoechogenic or anechogenic cavitary lesion on the ovary region. These findings were consistent with an ovarian cyst. Thereafter highly suspected ovarian cysts by diagnostic imaging were supported by high estrogen concentration on hormonal assay and the results of Pathologic examination as the unilateral ovarian cysts with secondary pyometra.
