Sadiah Boonstra 국립민속박물관 2009 International Journal of Intangible Heritage Vol.4 No.-
The Tropenmuseum in Amsterdam, in the Netherlands,was founded as a colonial museum in the 19th century inwhich experts (‘outsiders’) presented their view of othercultures. In the 20th century the Netherlands became amulticultural society. As a result, the museum had toredefine its function in society. In an attempt to rethink therelation between the content of its exhibitions and itsaudience, the Tropenmuseum refurbished all the museumgalleries between 1990 and 2008. During the refurbishmentthe museum started to experiment with intangible heritagefor which the story of Layla and Majnun was chosen as acase study. The museum collected four separatecontemporary cultural expressions of the story,accompanied by audiovisual recordings of performances. The experiment was so successful that it functioned as acatalyst for the final refurbished gallery, entitled TravellingTales, which is entirely devoted to intangible heritage. Based on research into the Layla and Majnun collection,I argue that the voices and views of the artists mirror themanifold perspectives that people have to various forms ofintangible and tangible culture. The presentation of thismultitude of views in the exhibition reflects the complexityof identification processes and therefore goes beyondnotions of ‘self’ and ‘other’. In this respect, theTropenmuseum functions as a forum where variousopinions meet and as a space for intercultural encounters.

Towards Safety Based Design Procedure for Ships
Bakker, Marijn,Boonstra, Hotze,Engelhard, Wim,Daman, Bart The Society of Naval Architects of Korea 2001 Journal of ship and ocean technology Vol.5 No.3
Present-day rules and regulations for the design and construction of ships are almost without exemption of a prescriptive and deterministic nature. Often it is argued that this situation is far from ideal; it does no right to the advances, which have been made during the past decades in engineering tools in marine technology, both in methodology and in computational power. Within IMO this has been realized for some time and has resulted in proposals to use Formal Safety Assessment(FSA) as a tool to improve and to modernize the rule making process. The present paper makes use of elements of the FSA methodology, but instead of working towards generic regulations or requirements, a Risk Assessment Approach, not unlike a 'safety case'; valid for a certain ship or type of ship is worked out. Delft University of Technology investigated the application of safely assessment procedures in ship design, in co-operation with Anthony Veder Shipowners and safety experts from Safely Service Center BV. The ship considered is a semi-pressurized-fully refrigerated LPG carrier. On the basis of the assumption that a major accident occurs, various accident, scenarios were considered and assessed, which would impair the safety of the carrier. In a so-called Risk Matrix, in which accident frequencies versus the consequence of the scenarios are depicted, the calculated risks all appeared lo be in the ALARP('as low as reasonable practicable') region. A number of design alternatives were compared, both on safety merits and cost-effectiveness. The experience gained with this scenario-based approach will be used to establish a set of general requirements for safety assessment techniques in ship design. In the view that assessment results will be most probably presented in a quasi-quantified manner, the requirements are concerned with uniformity of both the safety assessment. These requirements make it possible that valid comparison between various assessment studies can be made. Safety assessment, founded on these requirements, provides a validated and helpful source of data during the coming years, and provides naval architects and engineers with tools experience and data for safety assessment procedures in ship design. However a lot of effort has to be spent in order to make the methods applicable in day-to-day practice.

Olfactory neuropathology in Alzheimer’s disease: a sign of ongoing neurodegeneration
( Gowoon Son ),( Ali Jahanshahi ),( Seung-jun Yoo ),( Jackson T. Boonstra ),( David A. Hopkins ),( Harry W. M. Steinbusch ),( Cheil Moon ) 생화학분자생물학회(구 한국생화학분자생물학회) 2021 BMB Reports Vol.54 No.6
Olfactory neuropathology is a cause of olfactory loss in Alzheimer’s disease (AD). Olfactory dysfunction is also associated with memory and cognitive dysfunction and is an incidental finding of AD dementia. Here we review neuropathological research on the olfactory system in AD, considering both structural and functional evidence. Experimental and clinical findings identify olfactory dysfunction as an early indicator of AD. In keeping with this, amyloid-β production and neuro-inflammation are related to underlying causes of impaired olfaction. Notably, physiological features of the spatial map in the olfactory system suggest the evidence of ongoing neurodegeneration. Our aim in this review is to examine olfactory pathology findings essential to identifying mechanisms of olfactory dysfunction in the development of AD in hopes of supporting investigations leading towards revealing potential diagnostic methods and causes of early pathogenesis in the olfactory system.

<P><B>Abstract</B></P> <P>Synchronization between oscillatory signals is considered to be one of the main mechanisms through which neuronal populations interact with each other. It is conventionally studied with mass-bivariate measures utilizing either sensor-to-sensor or voxel-to-voxel signals. However, none of these approaches aims at maximizing synchronization, especially when two multichannel datasets are present. Examples include cortico-muscular coherence (CMC), cortico-subcortical interactions or hyperscanning (where electroencephalographic EEG/magnetoencephalographic MEG activity is recorded simultaneously from two or more subjects). For all of these cases, a method which could find two spatial projections maximizing the strength of synchronization would be desirable. Here we present such method for the maximization of coherence between two sets of EEG/MEG/EMG (electromyographic)/LFP (local field potential) recordings. We refer to it as canonical Coherence (caCOH). caCOH maximizes the absolute value of the coherence between the two multivariate spaces in the frequency domain. This allows very fast optimization for many frequency bins. Apart from presenting details of the caCOH algorithm, we test its efficacy with simulations using realistic head modelling and focus on the application of caCOH to the detection of cortico-muscular coherence. For this, we used diverse multichannel EEG and EMG recordings and demonstrate the ability of caCOH to extract complex patterns of CMC distributed across spatial and frequency domains. Finally, we indicate other scenarios where caCOH can be used for the extraction of neuronal interactions.</P> <P><B>Highlights</B></P> <P> <UL> <LI> We developed a novel multivariate method for the detection of neural synchronization. </LI> <LI> Canonical Coherence (caCOH) maximizes coherence between two datasets. </LI> <LI> caCOH was validated in simulations and real data. </LI> <LI> caCOH is applicable for diverse brain-brain or brain-periphery signals (EEG/MEG/LFP/EMG). </LI> </UL> </P>
