Bovine theileriosis caused by Theileria sergenti is a tick-borne hematoprotozoan disease that is characterized by chronic anemia and fever in cattle. In this study, results of microscopic examination and PCR detection confirmed 17 Korean native cattle with emaciation and fever as acute bovine theileriosis caused by T. sergenti. Buparvaquone was injected as treatment, but was proved to be an inappropriate measure according to our study. After 6 months of injection, clinical signs and hematological values were recovered, but T. sergenti was still identified in blood sample as a result of microscopic exam and PCR. These results suggest that continuous management is necessary to control bovine theileriosis. Therefore, findings of this study may provide significant guideline on the control of bovine theileriosis.

This research proposes a framework of buffer management for multi-project systems in the critical chain project management (CCPM) method, expressed in the form of max-plus linear (MPL) representation. Since time buffers are inserted in the projects for absorbing uncertainties in task durations and protecting the completion times, the proposed method provides a procedure for frequently surveying the rates of consumed buffers and the rate of elapsed times. Their relation expresses the performance of the projects which is plotted on a chart through the completed processes. The chart presents the current performance of the projects and their interaction, which alerts managers to make necessary decisions at the right time for managing each project and the entire multi-project system. The proposed framework can analyze the complex system readily, and it enables managers to make an effective decision on scheduling. The effectiveness of the framework is demonstrated through a numerical example.

Purpose Domestic asset management fintech companies are expected to grow by leaps and bounds along with the implementation of the "Data bills." Contrary to the market fever, however, academic research is insufficient. Therefore, we want to analyze user reviews of asset management fintech companies that are expected to grow significantly in the future to derive strengths and complementary points of services that have been provided, and analyze key elements of asset management fintech companies. Design/methodology/approach To analyze large amounts of review text data, this study applied text mining techniques. Bank Salad and Toss, domestic asset management application services, were selected for the study. To get the data, app reviews were crawled in the online app store and preprocessed using natural language processing techniques. Topic Modeling and Aspect-Sentiment Analysis were used as analysis methods. Findings According to the analysis results, this study was able to derive the elements that asset management fintech companies should have. As a result of Topic Modeling, 7 topics were derived from Bank Salad and Toss respectively. As a result, topics related to function and usage and topics on stability and marketing were extracted. Sentiment Analysis showed that users responded positively to function-related topics, but negatively to usage-related topics and stability topics. Through this, we were able to extract the key elements needed for asset management fintech companies.

The emergence of highly contagious viral diseases of livestock and poultry such as foot-and-mouth disease (FMD), African swine fever (ASF) and highly pathogenic influenza (HPAI) have necessitated the formulation of policies and regulatory frameworks for preventing ingress of exotic diseases and controlling dissemination of endemic diseases within the country. The disease control ratings to manage contagious livestock disease in farms have not being widely used because the evaluation parameters were not being considered inappropriate. The purpose of this study was to reinforce the validity of the parameters for evaluation factors and the objectivity of the scoring criteria in the application of the current disease management rating system. The diseases subject to intensive management were improved by reflecting farm situation. For the evaluation based on the disease grading system of farms, the diseases subject to intensive management were realized, the list of diseases for evaluating the vaccination rate was revised, and the quarantine and sanitation management standards were revised. The effectiveness of the improved livestock disease management system was confirmed through the application of actual pig farms. Therefore, this system will be used as a means to evaluation the biosecurity at the farm units. Through this, it will contribute to establish effective biosecurity measures for each farm by improving and supplementing the present disease grading system.

Twenty-five patients with perforation of esophagus were managed at Pusan National University Hospital, from 1981 to 1993. The hospital course of 14 of these patients was evaluated with a special emphasis on the cause and location of perforation, clinical presentation, time elapsed from perforation to treatment, method of treatment, and outcome. Patients with anastomotic leak and cancer were excluded.The perforation was iatrogenic in 7 patients, spontaneous in 5, ingestion of foreign body in 1, and traumatic in 1. There were 7 cervical perforations, 2 upper thoracic perforations, and 5 lower thoracic perforations. Chest pain, fever, and dyspnea were frequent symptoms. Esophagography was most diagnostic [11 patients] but thoracentesis was of little diagnostic aid.Antibiotics were administered intravenously to all patients:hyperalimentation was accomplished intravenously in 11, and nasogastric suction was used in all cases. No patient required any surgical procedure, minor or major.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.
