  • The HELlOS-MASTER code system is verified through the benchmark of the critical experiments that were performed by RRC "Kurchatov Institute" with water-moderated hexagonally pitched lattices of highly enriched Uranium fuel rods (8Ow/o). We also used the same input by using the MCNP code that was described in the evaluation report, and compared our results with those of the evaluation report. HELlOS, developed by Scandpower A/S, is a two-dimensional transport program for the generation of group cross-sections, and MASTER, developed by KAERI, is a three-dimensional nuclear design and analysis code based on the two-group diffusion theory. It solves neutronics model with the AFEN (Analytic Function Expansion Nodal) method for hexagonal geometry. The results show that the HELIOSMASTER code system is fast and accurate enough to be used as nuclear core analysis tool for hexagonal geometry.ometry.

  • Noma is a gangrenous disease of the orofacial region that leads to severe facial tissue destruction and is a significant cause of death among children. With the advent of modern antibiotics and improved nutrition, children with noma may survive into adulthood, but must face the challenge of undergoing repair of the sequelae of noma. This report describes a case of bony fusion of the maxilla and mandible in a 28-year-old female patient, which was a sequelae of a childhood case of noma.

  • Nanoparticle exposure assessment presents a unique challenge in the field of occupational and environmental health. With the commercialization of nanotechnology, exposure usually starts from the workplace and then spreads to environment and consumer exposure. This report discusses the current trends of nanoparticle exposure assessment, including the definition of nanotechnology relevant terms, essential physicochemical properties for nanomaterial characterization, current international activities related nanomaterial safety, and exposure assessment standard development for nanotechnology. Further this report describes challenges of nanoparticle exposure assessment such as background measurement, metrics of nanoparticle exposure assessment and personal sampling.

  • We report a case of 15 year-old female patient with a ossified chronic epidural hematoma. She had had head trauma 10 weeks previously and conservative care for delayed onset epidural hematoma at other hospital. Ossification was identified about 4 weeks after head injury and then progressed rapidly. We removed the chronic epidural hematoma with thick capsule and newly formed bone. The mechanism of the ossification associated with cephalhematoma and chronic subdural hematoma is reviewed and discussed.

  • A 12-year-old castrated male Persian cat presented with abdominal distension and anorexia. The radiography revealed ascites, pleural effusion, and a cranioventral mediastinal mass. Ultrasonography showed a well-defined mass lesion within a thickened ileal segment with a transmural loss of layering and multiple hyperechoic nodules arising from the peritoneum. Computed tomography showed peritoneal thickening with contrast enhancement, a bulky heterogeneous ileal mass, and mesenteric involvement with diffuse nodules. An alimentary lymphoma was confirmed by fine needle aspiration of the small intestinal mass. This report describes the imaging features of lymphoma with peritoneal lymphomatosis in a cat.

  • Hepatic hemangiomas infrequently exhibit atypical imaging features, which may cause diagnostic confusion with hepatic malignancies and lead to unnecessary surgery. We report a rare case of multilocular cystic hemangioma of the liver mimicking a mucinous cystic neoplasm of the liver in a 48-year-old female, focusing on computed tomography and magnetic resonance imaging features and their differential diagnosis.

  • Arterial injuries in the gluteal region caused by a knife are rare but serious, with mortality rates of up to 25%. This case report presents the management of a young male patient admitted to the emergency department in hypovolemic shock, with uncontrollable bleeding from an isolated penetrating gluteal injury. Additionally, the details of the surgical approach employed are discussed.

  • Objectives : The purpose of this report is to report the effect of acupotomy for patients with congestive heart failure. Methods: We treated 1 patient who has dyspnea due to congestive heart failure with acupotomy. To check the effect and satisfaction of acupotomy we used New York Heart Association class(NYHA class), Modified Borg Scalw Dyspnea Index(Borg Index), Baseline Dyspnea Index(BDI), Five-point Likert scale. Results : After 1 month of treatment, the patient felt much better in breathing, and had better score in NYHA class, Borg Index, BDI. Conclusions : This report demonstrates that acupotomy therapy has useful effect on congestive heart failure, but the more cases and researches are needed.

  • Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.
