독일에서의 환경영향의 정량적 평가

Kraft, Burkhard Schweppe 한국환경영향평가학회 1993 환경영향평가 Vol.2 No.2

Evaluation methods are employed in environmental impact assessment to choose between different project site, to determine the required measures to compensate impact and to decide whether the environmental impacts are more important than the social or economic effects of a project. The main obstacles that restrict use of quantitative evaluation method are a lack of knowledge about the environmental effects (e.g. if impacts on wildlife or landscape amenities are predicted) and the relative importance of economic and social issues compared with nature conservation stability of ecosystem orlandscape beauty. In Germany, the most common method for site planning is the "ecological risk analysis". It is a kind of multi-criteria-decision-method based on quantitative and qualitative description and ordinal ranking. The various kinds of "ecological balancing methods" that are more recently developed (within the last decade) to quantify the required amount for compensatory measures instead often use cardinal figures to express the value of ecosystems, the intensity of impacts, the need for additional measures to compensate for long recuperative periods when restoring ecosystems and so on. There are still only a view attempts to quantify decisions between environmental and socio-economic issues. Multicriteria-analysis as well as cost-benifit-analysis was used. Some new approaches which are still in a preliminary status are based on contingent valuation and on calculations for compensatory payments (instead of compensatory measures).

EEG-based usability assessment of 3D shutter glasses

Wenzel, Markus A,Schultze-Kraft, Rafael,Meinecke, Frank C,Fabien Cardinaux,Kemp, Thomas,Klaus-Robert Mü,ller,Gabriel Curio,Benjamin Blankertz IOP 2016 Journal of neural engineering Vol.13 No.1

<P> <I>Objective.</I> Neurotechnology can contribute to the usability assessment of products by providing objective measures of neural workload and can uncover usability impediments that are not consciously perceived by test persons. In this study, the neural processing effort imposed on the viewer of 3D television by shutter glasses was quantified as a function of shutter frequency. In particular, we sought to determine the critical shutter frequency at which the ‘neural flicker’ vanishes, such that visual fatigue due to this additional neural effort can be prevented by increasing the frequency of the system. <I>Approach.</I> Twenty-three participants viewed an image through 3D shutter glasses, while multichannel electroencephalogram (EEG) was recorded. In total ten shutter frequencies were employed, selected individually for each participant to cover the range below, at and above the threshold of flicker perception. The source of the neural flicker correlate was extracted using independent component analysis and the flicker impact on the visual cortex was quantified by decoding the state of the shutter from the EEG. <I>Main Result.</I> Effects of the shutter glasses were traced in the EEG up to around 67?Hz—about 20?Hz over the flicker perception threshold—and vanished at the subsequent frequency level of 77?Hz. <I>Significance.</I> The impact of the shutter glasses on the visual cortex can be detected by neurotechnology even when a flicker is not reported by the participants. <I>Potential impact.</I> Increasing the shutter frequency from the usual 50?Hz or 60?Hz to 77?Hz reduces the risk of visual fatigue and thus improves shutter-glass-based 3D usability.</P>

PHYLOGENETIC RELATIONSHIPS AMONG LINEAGES OF THE CERAMIACEAE (CERAMIALES, RHODOPHYTA) BASED ON NUCLEAR SMALL SUBUNIT rDNA SEQUENCE DATA¹

Choi, Han-Gu,Kraft, Gerald T.,Kim, Hyung-Seop,Guiry, Michael D.,Saunders, Gary W. Blackwell Publishing Ltd 2008 Journal of phycology Vol.44 No.4

<P>Phylogenetic relationships among 69 species of the Ceramiales (51 Ceramiaceae, six Dasyaceae, seven Delesseriaceae, and five Rhodomelaceae) were determined based on nuclear SSU rDNA sequence data. We resolved five strongly supported but divergent lineages among the included Ceramiaceae: (i) the genus <I>Inkyuleea</I>, which weakly joins other orders of the Rhodymeniophycidae rather than the Ceramiales in our analyses; (ii) the tribe Spyridieae, which is sister to the remainder of the included ceramialean taxa; (iii) the subfamily Ceramioideae, weakly including the tribe Warrenieae; (iv) the subfamily Callithamnioideae; and (v) the subfamily Compsothamnioideae, which emerges as sister to the Dasyaceae/Delesseriaceae/Rhodomelaceae complex, thus rendering the Ceramiaceae sensu lato unequivocally paraphyletic, as has been argued separately on anatomical grounds by Kylin and Hommersand. Our data support a restricted concept of the Ceramiaceae that includes only one of the five lineages (Ceramioideae) that we have resolved. In addition to failing to ally with the Ceramiales in our molecular analyses, species of <I>Inkyuleea</I> differ substantially from other Ceramiaceae sensu lato in details of pre- and postfertilization development. The genus <I>Inkyuleea</I> is here assigned to the Inkyuleeaceae fam. nov., which we provisionally retain in the Ceramiales. Species of <I>Spyridia</I> also differ from the remaining Ceramiaceae in their postfertilization development, and, in light of our molecular data, the genus <I>Spyridia</I> is assigned to the Spyridiaceae. The Callithamnioideae is strongly monophyletic (100% in all analyses), which, in combination with key anatomical differences, supports elevation to family status for this lineage as the Callithamniaceae. Similarly, the Compsothamnioideae is solidly monophyletic in our molecular trees and has a unique suite of defining anatomical characters that supports family status for a complex that we consider to include the tribes Compsothamnieae, Dasyphileae, Griffithsieae, Monosporeae, Ptiloteae, Spermothamnieae, Sphondylothamnieae, Spongoclonieae, and Wrangelieae, for which the reinstated family name Wrangeliaceae is available.</P>

Alcohol use disorder in the intensive care unit; a highly morbid condition; chemical dependency discussions during admission improves outcomes

Colling Kristin P.,Alexandra K. Kraft,Harry Melissa L. 대한중환자의학회 2023 Acute and Critical Care Vol.38 No.1

Background Alcohol use disorders (AUD) are common in patients admitted to intensive care units (ICU) and increase the risk for worse outcomes. In this study, we describe factors associated with patient mortality after ICU admission and the effect of chemical dependency (CD) counseling on outcomes in the year following ICU admission. Methods We retrospectively reviewed patient demographics, hospital data, and documentation of CD counseling by medical providers for all ICU patients with AUD admitted to our institution between January 2017 and March 2019. Primary outcomes were in-hospital and 1-year mortality. Results Of the 527 patients with AUD requiring ICU care, median age was 56 years (range, 18–86). Both in-hospital (12%) and 1-year mortality rates (27%) were high. Rural patients, comorbidities, older age, need for mechanical ventilation, and complications were associated with increased risk of in-hospital and 1-year mortality. CD counseling was documented for 73% of patients, and 50% of these patients accepted alcohol treatment or resources prior to discharge. CD evaluation and acceptance was associated with a significantly decreased rate of readmission for liver or alcohol-related issues (36% vs. 58%; odds ratio [OR], 0.41; 95% confidence interval [CI], 0.27–0.61) and 1-year mortality (7% vs. 19.5%; OR, 0.32; 95% CI, 0.16–0.64). CD evaluation alone, regardless of patient acceptance, was associated with a significantly decreased 1-year post-discharge mortality rate (12% vs. 23%; OR, 0.44; 95% CI, 0.25–0.77). Conclusions ICU patients with AUD had high in-hospital and 1-year mortality. CD evaluation, regardless of patient acceptance, was associated with a significant decrease in 1-year mortality.
