In a car accident in Kyongju, each of the two occupants insisted that he was not driving the car. The accident was investigated to determine who the driver is through careful review of the collision report, the statements of accident and witness, photographs taken at the scene, and the expert report of the National Institute of Scientific Investigation. The accident was reconstructed based on the physical principles, injuries of occupants, damages of the involved vehicles and their final stops. A mistake was found in the expert report.

The purpose of this study was to survey the problem of teachers' narrative reporting of children's science learning in elementary school report cards. For the purposes of this study, a questionnaire, comprised of 6 questions and an analysis tool (Cronbach's $\alpha=.70$) were developed to categorize the answers. The survey was conducted by 53 teachers, who are currently taking 5th ade in elementary school, and the results are as follows: First, they interpreted the same content of report cards in a variety of different ways. Second, they exhibited a number of different principles and criteria in terms of preparing the content of narrative report cards. Third, they experienced difficulties in preparing narrative report cards on science teaming which required explanation of complete processes. Fourth, most teachers surveyed answered that the content of their narrative reports on science learning did not communicate specifically the students' achievement and further studies. Fifth, the activities related to preparing the content of the science learning on narrative reports was widely perceived to be useless for teachers' professional development. Finally, teachers made a number of alternative proposals to overcome the current, perceived problems of teachers' narrative reporting for children's science learning in report cards. Based on the results of this analysis, alternative forms and content of narrative reports on science learning were discussed.

A nasal-type extranodal natural killer/T-cell lymphoma is considered an aggressive form of non-Hodgkin's lymphoma, with approximately half of all patients relapsing during the follow-up period, and most relapses occurring within the first 2 years of remission. Here we report an unusual case of a 42-year-old man who experienced recurrence in single pleura after 8 years of remission.

Extensive tumoral calcinosis affecting a large joint is uncommon in patients with systemic sclerosis. We report the case of a 52-year-old female patient referred for a growing calcified mass in the shoulder. She was diagnosed with interstitial lung disease and progressive systemic sclerosis. Although the pain and disability associated with the affected joint was not severe, the patient underwent surgical excision because the mass continued to grow and was likely to produce shoulder dysfunction and skin ulceration. The patient appeared well 10 months after surgery with no signs of recurrence. This report highlights the timing and indication of surgical excision in similar cases.

Although malignant transformation of meningiomas has been reported, it is extremely rare in meningiomas of ventricular system. Less than 2% of all meningiomas show malignant transformation from benign meningioma. We report a case of meningioma with early recurrence and malignant transformation and investigated possible underlying factors using immunohistochemistry for PCNA and p53 protein expression.

During a survey of fungal diversity in Korea, two fungal strains, KNU17-1 and KNU17-199, were isolated from paddy field soil in Yangpyeong and Sancheong, respectively, in Korea. These fungal isolates were analyzed based on their morphological characteristics and the molecular phylogenetic analysis of the internal transcribed spacer (ITS) rDNA sequences. On the basis of their morphology and phylogeny, KNU17-1 and KNU17-199 isolates were identified as Albifimbria verrucaria and Deconica coprophila, respectively. To the best of our knowledge, A. verrucaria and D. coprophila have not yet been reported in Korea. Thus, this is the first report of these species in Korea.

Acute ophthalmoparesis that includes the oculomotor, trochlear, or abducens nerve may occur as an initial presentation of Miller Fisher syndrome (MFS). The symptoms of MFS or variant forms of Guillain-Barre syndrome are pathogenically related to anti-GQ1b antibodies. We report a case of a 36-year-old man with unilateral isolated abducens nerve palsy associated with anti-GM1 antibody. To the best of our knowledge, this is the first report of unilateral isolated abducens nerve palsy with positivity for anti-GM1 immunoglobulin M antibody.

This report describes the first clinical case of a transfusion-associated Mycoplasma haemocanis infection in a dog in Korea. A 6-year-old male Maltese underwent a red blood cell transfusion for idiopathic immune-mediated hemolytic anemia. Eighteen days after the blood transfusion, the recipient's packed cell volume decreased and basophilic organisms were found on erythrocytes. A polymerase chain reaction and sequential analysis showed that both the donor dog and recipient dog had M. haemocanis. Six weeks after doxycycline administration, no organisms were detected and the recipient's anemia had improved.

Other than gunshot injuries, sacral penetrating injuries with a foreign body exiting to the other side are extremely rare. We encountered a case of sacral injury in which a long metallic pipe penetrated from the anus into the lower back of a patient. Since the pelvis contains various organs, management of a penetrating injury requires multidisciplinary treatment involving several medical specialties. Due to the infrequency of this type of injury, there are no definitive guidelines for effective management. We described our experience surgically treating a sacral penetrating injury and conducted a literature review. On this basis, we suggest a surgical strategy for treating this type of injury.

Symptomatic extravasation of irrigation fluid is a rare complication of hip arthroscopy. However, depending on the amount of fluid, intra-abdominal hypertension (IAH) may occur and even develop into abdominal compartment syndrome, which can seriously alter hemodynamic circulation. Therefore, it is important for anesthesiologists to promptly recognize the abnormal signs of IAH for early diagnosis and better clinical outcomes. Nevertheless, these signs are difficult to detect because they are usually obscured when the patient is under anesthesia and masked by surgical drapes. We report a case of IAH under general anesthesia during hip arthroscopy to highlight possible symptoms and signs.
