Purpose: The Tox-Info system is a poisonous substance information database developed by the Korean National Institute of Food and Drug Safety Evaluation. The aim of this study was to estimate the coverage effectiveness of the Tox-Info system by comparing the toxic substances included in the database with the distribution of the toxic substances implicated in the cases of intoxicated patients presenting to emergency departments. The secondary aim of the study was to propose any additional substances that should be added to the database. Methods: We retrospectively reviewed the medical records of patients suffering with toxic exposure who had visited any of 12 selected emergency departments in Korea from January 2010 to December 2011. The identified toxic substances were classified into groups including prescription drugs, agricultural chemicals, household products, animals or plants, herbal drugs, and others. We calculated the coverage rate of the Tox-Info database relative to the number of intoxication cases and the type of toxic substances involved. Results: A total of 5,840 intoxicated patient records were collected. Their mean age was 46.6±20.5 years and 56.2% were female. Of the total intoxication cases, 87.8% of the identified toxic substances were included in the Tox-Info database, while only 41.6% of all of the types of identified toxic substances were included. Broken down by category, 122 prescription drugs, 15 agricultural chemicals, 12 household products, 14 animals or plants and 2 herbal drugs involved in poisoning cases were not included in the Tox-info database. Conclusion: This study demonstrated the clinical usefulness of the Tox-Info system. While 87.8% of the substances involved in the cases were included in the Tox-Info database, the database should be continuously updated in order to include even the most uncommon toxic substances.

A new blade has been developed to apply to Doosan 3MW offshore wind turbine named as WinDS3000TM. The 3MW blade has been designed by the concept of slim external shape and optimized structure. High-performance glass fiber reinforced epoxy composites were used as the main material of the blade. The blade was manufactured using vacuum infusion process in order to increase the fiber volume fraction and to reduce micro-porosities. The blade has successfully passed the full-scale blade static test for certification. During the test, micro-failure signal and strain change of the blade were measured using acoustic emission sensors and strain gages. The blade has robust structure and weighs lighter compared to conventional blade since the new blade was designed by optimization process. The 3MW blade will be commercially applied to WinDS3000^{TM} in 2010.

농어류의 교잡종 생산 가능성을 알아보기 위해 농어(♀)×점농어(♂) 및 점농어(♀)×농어(♂)의 난과 자치어 발생을 조사하였다. 교잡종간 난발생과정에는 거의 차이가 없었다. 농어와 점농어의 정역교배에 의해 생산된 수정란의 수온에 따른 부화 시간과 부화율은, 농어(♀)×점농어(♂)의 경우 20.0℃에서 48시간 20분, 68.3%, 18.0℃에서 50시간 25분, 70.6%, 16.0℃에서 70시간, 76.8%였고, 점농어(♀)×농어(♂)의 경우 20.0℃에서 48시간 30분, 70.5%, 18.0℃에서 50시간 5분, 73.8%였다. 농어(♀)×점농어(♂)과 점농어(♀)×농어(♂)의 부화 직후 자어는 전장이 각각 4.17±0.06 ㎜, 3.80±0.03㎜로 비슷하였다. 그러나 흑색소포가 농어(♀)×점농어(♂)에서는 체표면에 전체적으로 분포하였으나, 점농어(♀)×농어(♂)에서는 항문을 전후로 짙게 띠를 형성하고 있었다. 이들은 부화 4일째부터 섭이를 시작하여 44일째에 치어기에 이르렀다. 치어기에 이른 시기의 전장은 농어(♀)×점농어(♂)가 15.27±0.33 ㎜, 점농어(♀)×농어(♂)가 17.00±0.50 ㎜로 유의차는 없었다. 교잡의 자치어기 일령과 전장의 관계에 대한 회귀직선식은 농어(♀)×점농어(♂)가 Y = 0.2722X + 3.3277 (r = 0.9786), 점농어(♀)×농어(♂)은 Y = 0.2895X + 3.2526 (r = 0.9779)로 나타났다. For the possibility of hybrid production, we investigated the development of embryo and larvae in sea bass(♀)×spotted sea bass(♂) and spotted sea bass(♀)×sea bass(♂). There were few differences in the embryo developmental process among hybrids. Hatching rates were 76.8% (16.0℃, 70 hours), 70.6% (18.0℃, 50 hours 25 minutes), 68.3% (20.0℃, 48 hours 20 minutes) in sea bass(♀)×spotted sea bass(♂); 73.8% (18.0℃, 50 hours 5 minutes), 70.5% (20.0℃, 48 hours 30 minutes) in spotted sea bass(♀)×sea bass(♂). Melanophores appeared as the vertical band on lateral sides of the body in spotted sea bass(♀)×sea bass(♂), but not in sea bass(♀)×spotted sea bass(♂). The larvae of 4 days after hatching ate food in all groups. Hatched larvae took 44 days to develop into juveniles at 18~20℃ in all groups. Total length of the juveniles was 15.27±0.33 ㎜ and 17.00±0.50 ㎜ in sea bass(♀)×spotted sea bass(♂) and spotted sea bass(♀)×sea bass(♂), respectively. The relationship between the days (X) and the total length (Y) of larvae and juveniles were: sea bass(♀)×spotted sea bass(♂): Y=0.2722X + 3.3277 (r=0.9786) spotted sea bass(♀)×sea bass(♂): Y=0.2895X + 3.2526 (r=0.9779)

The purpose of this study was to identify the biomechanical factors that correlate with plantar fasciitis in non-obese patients whose body mass index were below 25 kg/m². The subjects were non-obese patients who were diagnosed as plantar fasciitis by clinical appearance, physical examination, and ultrasonographic findings (n=48), and non-obese control persons without clinical diagnosis of plantar fasciitis (n=30). The two groups were compared on fat pad thickness, ankle dorsiflexion range of motion (ROM), resting calcaneal stance position (RCSP), incidence of calcaneal spur, and calcaneal pitch. The results showed that, there were statistically significant differences between two groups in ankle dorsiflexion ROM, RCSP, and calcaneal pitch (p<0.05). Multiple logistic regression analysis showed ankle dorsiflexion ROM and RCSP strongly correlated with presence of plantar fasciitis as independent predictors (p <0.05). In conclusion, reduced ankle dorsiflexion ROM and negative RCSP (valgus tendency in rear foot) may be the biomechanical factors associated with plantar fasciitis in non-obese patients.
