The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.

Historically, the standard treatment for early-stage cervical cancer has been radical surgery in patients with operable disease. Patients with locally advanced disease (defined as FIGO stage IB2 and usually with tumors greater than 4 cm, IIB, III and IVA) are usually treated with radical radiotherapy, which consists of external beam radiotherapy and internal brachytherapy. However, the discovery that cervical cancer tumors are sensitive to chemotherapy led to the initiation of studies looking at adding chemotherapy to both radiotherapy and surgery. Following a National Cancer Institute (NCI) alert in 1999 (NCI 1999), chemoradiotherapy became the standard of care for women with locally advanced cervical cancer.

Background: In the absence of a vaccine or treatment, the most pragmatic strategies against an infectious disease pandemic are extensive early detection testing and social distancing. This study aimed to summarize public and workplace responses to Coronavirus Disease-19 (COVID-19) and show how the Korean system has operated during the COVID-19 pandemic. Method: Daily briefings from the Korean Center for Disease Control and the Central Disaster Management Headquarters were assembled from January 20 to May 15, 2020. Results: By May 15, 2020, 11,018 COVID-19 cases were identified, of which 15.7% occurred in workplaces such as health-care facilities, call centers, sports clubs, coin karaoke, and nightlife destinations. When the first confirmed case was diagnosed, the Korean Center for Disease Control and Central Disaster Management Headquarters responded quickly, emphasizing early detection with numerous tests and a social distancing policy. This slowed the spread of infection without intensive containment, shut down, or mitigation interventions. After entering the public health blue alert level, a business continuity plan was distributed. After entering the orange level, the Ministry of Employment and Labor developed workplace guidelines for COVID-19 consisting of social distancing, flexible working schedules, early identification of workers with suspected infections, and disinfection of workplaces. Owing to the intensive workplace social distancing policy, workplaces remained safe with only small sporadic group infections. Conclusion: The workplace social distancing policy with timely implementation of specific guidelines was a key to preventing a large outbreak of COVID-19 in Korean workplaces. However, sporadic incidents of COVID-19 are still ongoing, and risk assessment in vulnerable workplaces should be continued.

The observations on climate change show a clear increase in the temperature of the Earth's surface and the oceans, a reduction in the land snow cover, and melting of the sea ice and glaciers. The effects of climate change are likely to include more variable weather, heat waves, increased mean temperature, rains, flooding and droughts. The threat of climate change and global warming on human and animal health is now recognized as a global issue. This presentation is described an overview of the latest scientific knowledge on the impact of climate change on zoonotic diseases. Climate strongly affects agriculture and livestock production and influences animal diseases, vectors and pathogens, and their habitat. Global warming are likely to change the temporal and geographical distribution of infectious diseases, including those that are vector-borne such as West Nile fever, Rift Valley fever, Japanese encephalitis, bluetongue, malaria and visceral leishmaniasis, and other diarrheal diseases. The distribution and prevalence of vector-borne diseases may be the most significant effect of climate change. The impact of climate change on the emergence and re-emergence of animal diseases has been confirmed by a majority of countries. Emerging zoonotic diseases are increasingly recognized as a global and regional issue with potential serious human health and economic impacts and their current upward trends are likely to continue. Coordinated international responses are therefore essential across veterinary and human health sectors, regions and countries to control and prevent emerging zoonoses. A new early warning and alert systems is developing and introducing for enhancing surveillance and response to zoonotic diseases. And international networks that include public health, research, medical and veterinary laboratories working with zoonotic pathogens should be established and strengthened. Facing this challenging future, the long-term strategies for zoonotic diseases that may be affected by climate change is need for better prevention and control measures in susceptible livestock, wildlife and vectors in Korea. In conclusion, strengthening global, regional and national early warning systems is extremely important, as are coordinated research programmes and subsequent prevention and control measures, and need for the global surveillance network essential for early detection of zoonotic diseases.

The u-Healthcare system, a new paradigm, provides healthcare and medical service anytime, anywhere in daily life using wired and wireless networks. It only doesn't reach u-Hospital at home, to manage efficient personal health in fitness space, it is essential to feedback process through measuring and analyzing a personal vital signs. MBAN(Medical Body Area Network) is a core of this technology. MBAN, a new paradigm of the u-Healthcare system, can provide healthcare and medical service anytime, anywhere on real time in daily life using u-sensor networks. In this paper, an ontology-based context-awareness in MBAN proposed system development methodology. Accordingly, ontology-based context awareness system on MBAN to Elderly/severe patients/aged/, with measured respiratory rate/temperature/pulse and vital signs having small variables through u-sensor network in real-time, discovered abnormal signs and emergency situations which may happen to people at sleep or activity, alarmed and connected with members of a family or medical emergency alarm(Emergency Call) and 119 system to avoid sudden accidents for early detection. Therefore, We have proposed that accuracy of biological signal sensing and the confidence of ontology should be inspected.

Perforation of the gastrointestinal tract in neonatal period has been associated with a grim prognosis. Recently there has been some improvement in survival. To evaluate the remaining pitfalls in management, 19 neonatal gastrointestinal perforation cases from May 1989 to July 1996 were analysed retrospectively. Seven patients were premature and low birth weight infants. Perforation was most common in the ileum(56.3%). Mechanical or functional obstruction distal to the perforation site was identified in 7 cases; Hirschsprung's disease 3, small bowel atresia 3, and anorectal malformation 1. These lesions were often not diagnosed until operation. Five cases of necrotizing enterocolitis and 1 of muscular defect were the other causes of perforation. In six cases, the cause of the perforation was not identified. Perinatal ischemic episodes were associated in five cases. Overall mortality was 15.1%. Because a considerable number of gastrointestinal perforations resulted from distal obstruction, pediatric surgeon should be alert for early identification and intervention of gastrointestinal obstruction, particularly in patients that are premature and have a history of ischemia.

Trichloroethylene (TCE, $C_2HCl_3$), which was introduced as a gas for general anesthesia and analgesia in early 1900's has been widely used in industry as an organic solvent. Occupational exposure to TCE is an important medical problem. Manifestations of acute exposure to TCE include mucocutaneous irritation, hepatotoxicity, cognitive impairment, sleep, headache, respiratory insufficiency and death. We report a 38-year-old man who was admitted to a department of emergency medicine after occupational inhalation exposure to TCE. He rapidly developed semicoma and respiratory depression. After mechanical ventilation, hypercapnea and hypoxemia disappeared and his mental state again became alert. Careful evaluation and proper respiratory support are important for respiratory failure after occupational TCE inhalation.
