Drought is a recurrent natural hazard in Bangladesh. It has significant impacts on agriculture, environment, and society. Well-timed information on the onset, extent, intensity, duration, and impacts of drought can mitigate the potential drought-related losses. Thus, drought characteristics need to be explained in terms of frequency, severity, and duration. This paper aims to characterize the spatial and temporal pattern of meteorological drought using EDI and illustrated drought severity over Bangladesh. Twenty-seven (27) station-based daily rainfall data for the study period of 1981-2015 were used to calculate the EDI values over Bangladesh. The evaluation of EDI is conducted for 4 sub-regions over the country to confirm the historical drought record-developed at the regional scale. The finding shows that on average, the frequency of severe to extreme drought is approximately 0.7 events per year. As a result of the regional analysis, most of the recorded historical drought events were successfully detected during the study period. Additionally, the seasonal analysis showed that the extreme droughts were frequently hit in northwestern, middle portion of the eastern and small portion of central parts of Bangladesh during the Kharif(wet) and Rabi(dry) seasons. The severe drought was affected recurrently in the central and northern regions of the country during all cropping seasons. The study also points out that the northern, south-western and central regions in Bangladesh are comparatively vulnerable to both extreme and severe drought event. The study showed that EDI would be a useful tool to identify the drought-prone area and time and potentially applicable to the climate change-induced drought evolution monitoring at regional to the national level in Bangladesh. The outcome of the present study can be used in taking anticipatory strategies to mitigate the drought damages on agricultural production as well as human sufferings in drought-prone areas of Bangladesh.

Purpose: Injuries are the third leading cause of death in Korea. Isolated chest injury is not uncommon and shows high mortality and morbidity. Several scoring systems are used for triage and stratification for trauma patients, but no standard system is accepted. We aimed to analyze the accuracy of identification of isolated chest injury by using several scoring systems. Methods: We reviewed a total of 75 patients admitted with isolated chest injury between January 2005 and October 2005. Medical records were reviewed by using the Injury Severity Score (ISS), the Revised Trauma Score (RTS), and the Trauma and Injury Severity Score (TRISS). The scoring systems were compared by using statistics methods. Results: The overall predictive accuracy of the TRISS was 12.5%, 12.0% greater than those of the RTS and the ISS. By using the area under the receiver operating characteristic (AUROC) curve, the TRISS showed an excellent discriminative power (AUROC 0.931) compared to the ISS (AUROC 0.926) and the RTS (AUROC 0.872). Conclusion: Compared with the RTS and the ISS, the TRISS is an easily applied tool with excellent prognostic abilities for isolated chest trauma patients. However, the TRISS, the ISS, and the RTS showed high specificity and low sensitivity, so another scoring system is required for triage and stratification of isolated chest injury patients.

Purpose: We evaluated serum procalcitonin (PCT) as a diagnostic marker of neonatal sepsis, and compared PCT levels with C-reactive protein (CRP) levels. Methods: We retrospectively reviewed the medical records of 269 neonates with a suspected infection, admitted to Wonkwang University School of Medicine & Hospital between January 2011 and December 2012, for whom PCT and CRP values had been obtained. Neonates were categorized into 4 groups according to infection severity. CRP and PCT values were analyzed and compared, and their effectiveness as diagnostic markers was determined by using receiver operating characteristic (ROC) curve analysis. We also calculated the sensitivity, specificity, and positive, and negative predictive values. Results: The mean PCT and CRP concentrations were respectively $56.27{\pm}81.89$ and $71.14{\pm}37.17mg/L$ in the "confirmed sepsis" group; $15.64{\pm}32.64$ and $39.23{\pm}41.41mg/L$ in the "suspected sepsis" group; $9.49{\pm}4.30$ and $0.97{\pm}1.16mg/L$ in the "mild infection" group; and $0.21{\pm}0.12$ and $0.72{\pm}0.7mg/L$ in the control group. High concentrations indicated greater severity of infection (P<0.001). Five of 18 patients with confirmed sepsis had low PCT levels (<1.0 mg/L) despite high CRP levels. In the ROC analysis, the area under the curve was 0.951 for CRP and 0.803 for PCT. The cutoff concentrations of 0.5 mg/L for PCT and 1.0 mg/L for CRP were optimal for diagnosing neonatal sepsis (sensitivity, 88.29% vs. 100%; specificity, 58.17% vs. 85.66%; positive predictive value, 13.2% vs. 33.3%; negative predictive value, 98.6% vs. 100%, respectively). Conclusion: PCT is a highly effective early diagnostic marker of neonatal infection. However, it may not be as reliable as CRP.

Background: This study was performed to reveal the relationships between the cross-sectional areas (CSAs) of the paraspinal muscles and the severity of low back pain (LBP), including the level of disability. Methods: This single-center cross-sectional study was conducted on 164 patients with chronic LBP. The effects of demographic characteristics, posture, level of physical activity, disc herniation type, and sarcopenia risk on the CSAs of paraspinal muscles were evaluated along with the relationship between the CSAs and severity of pain and disability in all patients. The CSAs of paraspinal muscles were evaluated using the software program Image J 1.53. Results: A negative significant correlation was found between age and the paraspinal muscle's CSA (P < 0.05), whereas a positive correlation was present between the level of physical activity and the CSA of the paraspinal muscle at the L2-3 and L3-4 levels. The CSAs of paraspinal muscles in patients with sarcopenia risk was significantly lower than those in patients without sarcopenia risk (P < 0.05). The CSAs of paraspinal muscles at the L2-3 and L3-4 levels in obese patients were significantly higher than those in overweight patients (P = 0.028, P = 0.026, respectively). There was no relationship between the CSAs of paraspinal muscles and pain intensity or disability. Conclusions: Although this study did not find a relationship between paraspinal CSAs and pain or disability, treatment regimens for preventing paraspinal muscles from atrophy may aid pain physicians in relieving pain, restoring function, and preventing recurrence in patients with chronic LBP.

This paper confirmed the effect of Baekho-tang(白虎湯) on psoriasis patient diagnosed with Yangmyung-Yeoljeung(陽明熱證). We treated patients with psoriasis classified as Yangmyung-Yeoljeung(陽明熱證) according to Shanghanlun(傷寒論) with Baekho-tang(白虎湯). Two patients was treated with Baekho-tang(白虎湯) for 18 days and 75 days, respectively. Baekho-tang(白虎湯) used in the treatment consisted of Gypsum Fibrosum 16g, Oryza semen 12.5g, Anemarrhena Rhizoma 6g and Glycyrrhizae Radix 2g. The severity of psoriasis was evaluated by PASI(psoriasis area severity index) and pictures. Also we checked the change in Pruritus by VAS(visual analogue scale). After the Baekho-tang(白虎湯) treatment, the PASI of 2 patients decreased from 13 to 2.8 and from 10.8 to 0.8 respectively. In addition, VAS of 2 patients diminished from 10 to 3 and from 8 to 1 respectively. Moreover, no side effects were observed. We received effective results by giving Baekho-tang to Psoriasis patients with sweaty, dry mouth, and heating sensation. Anti-inflammatory, antipyretic effects and immunomodulatory functions of Baekho-tang(白虎湯) could lead to improvement of psoriasis.

Exserohilum turcicum is a fungus that causes northern corn leaf blight (NCLB) and has deleterious effects on maize production globally. Therefore, it is prudent to mitigate the effects of NCLB using genetic diversity. The objective of this research was to assess the severity of NCLB disease on the growth and yield of various maize genotypes. A randomized complete block design field experiment, replicated three times, was conducted to evaluate the effect of E. turcicum on 10 maize hybrids. Percent disease index, plant height, and leaf area were recorded at the silk stage. Cob weight, grain fresh weight, and grain yields were determined at harvest maturity. All measured parameters were significantly different (P<0.05) between the maize hybrids. Of the 10 genotypes, four (PAN 4R-528R, PAN 4R-728BR, PAN 3R-724BR, and P1788BR) were susceptible, five (DKC74-74BR, PAN 5R-582R, PAN 5R-890R, PAN 5R-854R, and PAN 5R-590R) were moderately susceptible, and one (DKC80-40BR) was moderately resistant. DKC80-40BR exhibited greater cob weight, while DKC74-74BR was superior in all other plant growth and yield components. Interestingly, although not significant (P>0.05) and high, maize growth and yield parameters had negative correlations with disease incidence, except for grain fresh weight. Therefore, DKC80-40BR may be selected for cultivation in areas prone to NCLB to reduce maize susceptibility to the disease, while DKC74-74BR may improve crop performance. These hybrids could be considered as potential sources of resistance or tolerance to NCLB for further validation by plant breeders.

본 연구에서는 다양한 기후변화 시나리오를 적용한 GCM으로부터 생산된 기상자료를 이용하여 남한지역 미래가뭄의 시공간적인 분포를 전망하였다. 가뭄을 정량적으로 분석하기 위하여 SPI(Standardized Precipitation Index)를 가뭄지수로 이용하였으며 가뭄빈도해석을 통하여 54개 기상관측소별 SDF(Severity-Duration-Fraquency) 곡선을 유도하여 남한지역의 지속기간별, 재현기간별 가뭄우심지역을 지도화하였다. 가뭄우심도에 의한 미래 가뭄전망 결과, 낙동강, 섬진강 유역이 과거와 동일하게 다른 유역에 비하여 가뭄이 심화될 것으로 전망되었으며 한강유역 역시 가뭄이 심화될 것으로 나타났다. 미래의 경우 A2 시나리오에서는 과거에 비해 낙동강 동해 유역에도 가뭄이 심화되는 지역이 확장되는 것으로 나타났으며 RCP8.5 시나리오에서는 중부지역에 위치한 한강유역의 가뭄이 심화될 것으로 예측되었다. 연구결과를 통해 미래 가뭄은 과거와 같이 남부지방에 국한되지 않고 한반도 전역에 걸쳐 광범위하게 나타날 것으로 전망되었고 기후변화 시나리오별, 기후모델별로 다소의 전망 차이를 나타내었다.
