This study is performed to consider the threshold values of heavy rain warning in Korea using 98 surface meteorological station data and 590 Automatic Weather System stations (AWSs), damage data of National Emergency Management Agency for the period of 2005 to 2009. It is in need to arrange new criteria for heavy rain considering concept of rainfall intensity and rainfall damage to reflect the changed characteristics of rainfall according to the climate change. Rainfall values from the most frequent rainfall damage are at 30 mm/1 hr, 60 mm/3 hr, 70 mm/6 hr, and 110 mm/12 hr, respectively. The cumulative probability of damage occurrences of one in two due to heavy rain shows up at 20 mm/1 hr, 50 mm/3 hr, 80 mm/6 hr, and 110 mm/12 hr, respectively. When the relationship between threshold values of heavy rain warning and the possibility of rainfall damage is investigated, rainfall values for high connectivity between heavy rain warning criteria and the possibility of rainfall damage appear at 30 mm/1 hr, 50 mm/3 hr, 80 mm/6 hr, and 100 m/12 hr, respectively. It is proper to adopt the daily maximum precipitation intensity of 6 and 12 hours, because 6 hours rainfall might be include the concept of rainfall intensity for very-short-term and short-term unexpectedly happened rainfall and 12 hours rainfall could maintain the connectivity of the previous heavy rain warning system and represent long-term continuously happened rainfall. The optimum combinations of criteria for heavy rain warning of 6 and 12 hours are 80 mm/6 hr or 100 mm/12 hr, and 70 mm/6 hr or 110 mm/12 hr.

Objectives: The purpose of this study was to report the short-term blood pressure-lowering effects observed in a patient with malignant hypertension through slow breathing maneuver with heart rate variability(HRV) biofeedback. Methods: Biofeedback sessions, totaling 13, each lasting 10 minutes, were administered. Blood pressure was measured pre and post-treatment, as well as thrice daily at 10 am, 4 pm, and 8 pm. Systolic blood pressure(SBP), diastolic blood pressure(DBP), and pulse rate were recorded for comparative analysis. Results: Before biofeedback, the average SBP, DBP, and pulse rate were 227.2±18.3, 135.2±11.0, and 104.4±5.3, respectively. Immediately post-biofeedback, these values changed to 213.7±15.2, 126.9±8.5, and 99.2±3.6. However, sustained long-term blood pressure reduction was not observed. Conclusions: The findings suggest that biofeedback therapy induces a short-term reduction in blood pressure in cases of malignant hypertension, potentially associated with autonomic nervous system regulation. Integrating biofeedback with other Korean medicine treatments, such as acupuncture or moxibustion, may offer a comprehensive approach for managing malignant hypertension.

IPCC 제5차 평가보고서에 따르면 극한강우의 빈도 및 강도가 증가할 가능성이 매우 높을 것으로 예측되고 있다. 실제로 극한강우에 따른 침수피해가 증가하고 있으며, 이에 따라 기후변화의 영향을 반영한 미래 확률강우량 추정이 필요하다. 본 연구에서는 기후변화 RCP 8.5 시나리오로부터 도출된 미래 연 최대 일강수량 자료의 추세분석과 scale-invariance 기법을 이용하여 미래 확률강우량을 추정하였다. 먼저, 기상청 관할 60개 기상관측소의 관측 강우자료를 이용하여 관측소별로 스케일 특성을 검토한 후, 현재기후 모의자료를 이용하여 scale-invariance 기법의 적용가능성을 검증하였다. 그 후, 미래 일 강수량 시계열을 scale-invariance 특성에 따라 유도된 IDF 곡선식에 적용하여 기후변화의 영향을 반영한 지속시간별 확률강우량을 추정하였다. 대부분의 지점에서 확률강우량이 증가할 것으로 예측되었으나, 일부 지역의 경우에는 감소할 가능성도 있음을 살펴볼 수 있다.

Purpose: Climate change affects human health and calls for a health forecasting service. The purpose of this study was to explore the students' actual use and their satisfaction with meteorological information and the demands on health forecasting at a university in South Kyungsang Province. Method: This study used a descriptive design through structured self-report questionnaires including frequency, contents, purpose, perception, satisfaction of meterological information and need and demand of health forecasting. Data were collected from June 1 to 5, 2009 and analyzed using the SPSS 17.0 program. Descriptive statistics, t-test, ANOVA, $\chi^2$ test and Person's correlation coefficient were used to analyze the data. Result: The majority of the students watched the daily weather information to decide about daily work, outdoor activity or habitually. The mean score of need for health forecasting was $3.44{\pm}.81$, and the demand for health forecasting was $2.93{\pm}1.05$. Significant differences were found in the need for health forecasting according to sex, major, and environmental disease. In addition, the higher the satisfaction of health forecasting, the higher the demand for it. Conclusion: I suggest improving the meteorological information system technically and developing a health forecasting service resulting in a healthier and more comfortable life.

Opioids profoundly inhibit evoked discharges of spinal nociceptive neurons, thereby inhibiting the transmission of pain. Intrathecal administration of opioids using implantable continuous infusion systems is an effective method of pain relief when other treatments have failed, as well as for patients with adequate analgesia on high dose therapy that produces unacceptable side effects. We report two cases of intrathecal pump implantation performed in patients suffering from intractable chronic pain. A test dose of 3 mg morphine was injected into the epidural space. No side effects were noted and patients experienced considerable pain relief. Implantation was performed one day after the test. The initial intrathecal morphine delivery dose was half of the equivalent dose of daily oral intake opioids and the infusion rate was increased gradually under close observation for opioid side effects. Two days post-implantation, both patients were discharged without any complications.

The impact on streamflow and groundwater recharge considering future potential climate and land use change was assessed using SLURP (Semi-distributed Land-Use Runoff Process) continuous hydrologic model. The model was calibrated and verified using 4 years (1999-2002) daily observed streamflow data for a $260.4km^2$ which has been continuously urbanized during the past couple of decades. The model was calibrated and validated with the coefficient of determination and Nash-Sutcliffe efficiency ranging from 0.8 to 0.7 and 0.7 to 0.5, respectively. The CCCma CGCM2 data by two SRES (Special Report on Emissions Scenarios) climate change scenarios (A2 and B2) of the IPCC (Intergovemmental Panel on Climate Change) were adopted and the future weather data was downscaled by Delta Change Method using 30 years (1977 - 2006, baseline period) weather data. The future land uses were predicted by CA (Cellular Automata)-Markov technique using the time series land use data of Landsat images. The future land uses showed that the forest and paddy area decreased 10.8 % and 6.2 % respectively while the urban area increased 14.2 %. For the future vegetation cover information, a linear regression between monthly NDVI (Normalized Difference Vegetation Index) from NOAA/AVHRR images and monthly mean temperature using five years (1998 - 2002) data was derived for each land use class. The future highest NDVI value was 0.61 while the current highest NDVI value was 0.52. The model results showed that the future predicted runoff ratio ranged from 46 % to 48 % while the present runoff ratio was 59 %. On the other hand, the impact on runoff ratio by land use change showed about 3 % increase comparing with the present land use condition. The streamflow and groundwater recharge was big decrease in the future.

This study reports the effectiveness of traditional Korean medicine in treating tetraplegia and respiratory symptoms (including dyspnea) after traumatic cervical spinal cord injury surgery. The patient was treated with complex Korean medical treatment including electroacupuncture, pharmacopuncture, and herbal medicine. The manual muscle test (expanded Medical Research Council system) was used to measure the patient's muscle strength. The Korean version of the modified Barthel index and the functional independent measure were used to evaluate the patient's independence in performing daily activities. Following 2 hospitalizations and treatments, the patient's muscle strength improved > 4+ score for all joints, and the Korean version of the modified Barthel index and functional independent measure scores increased from 26 to 79 and 56 to 95, respectively. Symptoms of dyspnea, coughing, and sputum gradually improved and finally disappeared during hospitalization. This study suggests complex Korean medicine treatment may be effective in the rehabilitation of post-surgical cervical spinal cord injury patients.

Idiopathic hyperhidrosis is a physically and emotionally distressing symptom, which lacks a precise definition. Although operative and nonoperative methods have been shown to be effective in the treatment of idiopathic hyperhidrosis, limitations, cautions and complications are inherent in their extended use. The purpose of this report is to describe the theraputetic effects of magnetic resonance for managing idiopathic hyperhidrosis. A 28 years old woman had been suffering from profuse sweating on both planter and palmar sides for 15 years. We successfully treated this symptom with the 6 magnetic resonance treatments without any complications. Now she lives well in a condition of normal sweating after the applications. It suggest that short daily periods of exposure to appropriate magnetic resonance can beneficially modulate the balance of autonomic nervous system that are responsible for sympathetic overflow, and that there is an effective window of induced electrical magnetism in which sympathetic function can be controlled in the absence of side effects.
