Objective： To identify the position of traditional herbal medicine in dementia research field using mapping technology. Methods： Keywords for dementia and traditional herbal medicine for treating dementia were used to extract scientific articles from the Web of Science database from January 2000 to July 2010. A co- occurrence matrix was created based on the concurrent set of author＇s keywords occurring in each scientific article, and technology network maps were created from similarity index matrices. Results： Twenty specialized research areas were identified in the dementia field, and the relationship strength was 0.2-0.6. Many research fields were associated with diagnosis and risk factors for dementia. Additionally, the mechanism or cause of dementia is an actively studied field. Traditional herbal medicine for treating dementia was located on a map near the cortical dementia diagnosis and therapy, and frontotemporal dementia research field with a relationship strength of 0.53 and 0.31-0.33 respectively, which demonstrates that traditional herbal medicine for dementia occupies an independent research area with a relationship to existing scientific research fields. Conclusion： Traditional herbal medicine can provide an alternative and complementary approach for treating dementia as evidenced by a scientific mapping analysis.

The electro-clean system (ECS), a ballast water management system that eliminates harmful aquatic organisms in ship ballast water via electrochemically produced chloride, was developed. The current density for potentiostatic experiments subjected to seawater with an applied potential (-0.1 V) at various TRC concentrations (2×10-6, 6×10-6, 10×10-6, and 15×10-6) have similar results. The current density at -0.1 V has the highest value compared with that at -0.7 V and -0.4 V. For all concentrations, the current density increases with increasing applied potential.

To obtain improved accuracy in predicting extracapsular extension （ECE） and seminal vesicle invasion （SVI）, we evaluated the variables affecting the predictability of staging magnetic resonance imaging （MRI, phased-array coil） and estimated their impact on accuracy between preoperative MRI staging and histological outcome. A total of 121 patients with localized or locally advanced prostate cancer who underwent robotic radical prostatectomy （RALP） were included. Following transrectal biopsy, all enrolled patients had undergone MRI for staging work-up. After RALP, only 43.8% （53/121） of the patients were matched with the MRI predicted stage. Compared to the matched group in the prediction of ECE, the unmatched group had significantly higher initial prostate-specific antigen （PSA, 12.8 ng m1-1 versus 8.1 ng m1-1, P=0.048）. In the prediction of SVI, initial PSA （8.1 ng ml- 1 versus 17.3 ng ml- 1, P=0.009） and biopsy Gleason score （6.5 versus 7.6, P=0.035） were significantly higher in the unmatched group. When applying clinical cutoffs of initial PSA of 10 and 20 ng ml-1, the accuracy of MRI in the prediction of ECE was decreased in the group with PSA over 20 ng ml- 1 （75.6, 64.5 and 37.5%, P=0.01）, and this group had significantly decreased accuracy of MRI in the prediction of SVI （91.5, 77.4 and 37.5%, P〈0.01）. Applying the clinical cutoff of a Gleason score of 7, the accuracy of MRI in the prediction of SVI was decreased in the higher G leason score group （93.9, 82.1 and 62.9%, P= 0.01）. Thus, for these patient groups, to obtain margin negativity during radical prostatectomy, operative findings, rather than post-biopsy MRI images, may provide substantial information, implying a clinical advantage in conducting MRI before prostate biopsy.
