Observation with hearts and hands

‘Observation with hearts and hands’ is the work suggesting the new point of view to the audiences as pulling out the human body enclosing personal and everyday life story into the exhibition space. When we observe the object, we cannot consider it just the way it is without any interference of our way of thinking and view because our observation is deeply rooted in our personal experiences and memories. This work is created to explore their own appearances reAlected in the mirror in daily life and to explore into the inside of the nose usually touched on their own. This giant nose was composed with various shapes of metaphorical objects recalling the texture of the liquid and solid. As enjoying the various kinds of sound and texture designed by the accordance with the step of exploration of the nose, the audiences will recollect the similar memories experienced alone in somewhere and someday. This unexpectedness confronting private behavior in public space will give fun to the audiences with ludicrous laughter. And also observing the inside of the nose through the endoscope will make the audiences to see our body like beautiful and imaginary world. The main message of this work is proposing the real meaning of observation. Whenever the audiences are enjoying this work, they are meeting unexpected gaze toward them. They usually did not notice these kinds of the gaze in their daily life, but the observation is always occurring mutually. We think we are only observing the object unilaterally, but, on the contrary, the object also observes us. This is what this work is about

Early vessel destabilization mediated by Angiopoietin-2 and subsequent vessel maturation via Angiopoietin-1 induce functional neovasculature after ischemia.

We assessed whether Angiopoietin-2 (Ang2), a Tie2 ligand and partial antagonist of Angiopoietin-1 (Ang1), is required for early vessel destabilization during postischemic angiogenesis, when combined with vascular growth factors. In vitro, matrigel co-cultures assessed endothelial-cell tube formation and pericyte recruitment after stimulation of VEGF-A, Apelin (APLN), Ang1 with or without Ang2. In a murine hindlimb ischemia model, adeno-associated virus (rAAV, 3×10(12) virusparticles) transduction of VEGF-A, APLN and Ang1 with or without Ang2 (continuous or early expression d0-3) was performed intramuscularly (d-14). Femoral artery ligation was performed at d0, followed by laser doppler perfusion meassurements (LDI) 7 and 14. At d7 (early timepoint) and d14 (late timepoint), histological analysis of capillary/muscle fiber ratio (CMF-R, PECAM-1) and pericyte/capillary ratio (PC-R, NG2) was performed. In vitro, VEGF-A, APLN and Ang1 induced ring formation, but only APLN and Ang1 recruited pericytes. Ang2 did not affect tube formation by APLN, but reduced pericyte recruitment after APLN or Ang1 overexpression. In vivo, rAAV.VEGF-A did not alter LDI-perfusion at d14, consistent with an impaired PC-R despite a rise in CMF-R. rAAV.APLN improved perfusion at d14, with or without continuous Ang2, increasing CMF-R and PC-R. rAAV.Ang1 improved perfusion at d14, when combined with rAAV.Ang2 (d0-3), accompanied by an increased CMF-R and PC-R. The combination of early vessel destabilization (Ang2 d0-3) and continuous Ang1 overexpression improves hindlimb perfusion, pointing to the importance of early vessel destabilization and subsequent vessel maturation for enhanced therapeutic neovascularization

Use of live video overlay on 3D data for distributed collaborative review

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 84-85).Using everyday skills, such as pointing and drawing freehand sketches, facilitates effective communication when reviewing visual information. However, for sharing three-dimensional (3D) data, it is difficult to support such approaches of using hands and real ink in a seamless way. This thesis proposes a new system design called AnnoScape as an approach to performing a remote collaborative review of 3D digital data using a live video overlay of the desktop image on the viewports of the 3D scene. The system's virtual viewports are controlled with tangible handles and can be left spatially in the 3D data space. The viewports can be shared with remote collaborators both asynchronously and in real time. The system allows distributed users to navigate shared 3D space individually or jointly (synchronizing the viewport); generate an overlay of the live video of hand drawings, physical objects, and printed images from the desktop surface with the viewport; and control the legibility of the visual contents. This spatial video overlay technique in the 3D data space allows distributed users to share the live annotations over the synchronized viewports. We report the prototype design and initial experiments to explore AnnoScape's possibilities through the scenario of having remote collaborators review the exterior site and interior reconfiguration of an existing architectural setting.by Austin Seungmin Lee.S.M

Chloride-Binding Capacity of Portland Cement Paste Blended with Synthesized CA 2

A chloride-binding capacity is the major factor to mitigate the ingress of chloride into concrete. This paper presents the chloride-binding capacity of Portland cement paste containing synthesized CA2 (CaO·2Al2O3). The CA2 was synthesized in the high-temperature furnace and characterized by X-ray diffraction for inspecting the purity. The synthesized CA2 was substituted for Portland cement by 0%, 5%, and 10% by weight, and the NaCl solution was used as an internal chloride, which is assumed as a total chloride. The chloride-binding capacity of cement paste was calculated from a water-soluble chloride extraction method by the application of the Langmuir isotherm equation. And the hydration products were analyzed using X-ray diffraction and thermogravimetric analysis. We demonstrate that the CA2 increases an AFm phase in the Portland cement system, and the incorporation of CA2 consequently enhances the chloride-binding capacity of cement paste samples

Need for Information and Communication Technology during COVID-19: An Exploratory Study Using Nurses’ Activity Diaries

Objectives The coronavirus disease 2019 (COVID-19) pandemic has led to high levels of burnout among nurses. Information and communication technology (ICT) may offer a solution to prevent a potential collapse in healthcare. The aim of this study was to identify areas where ICT could provide support, by analyzing the work of nurses during the COVID-19 pandemic. Methods This retrospective exploratory descriptive study analyzed qualitative data from the activity diaries of seven nurses working in COVID-19 wards or intensive care units. Results The nursing work process during COVID-19 involved “added tasks,” “changed tasks,” and “reduced tasks” compared to the pre-COVID-19 situation. Nurses reported difficulties in communicating with other healthcare professionals both inside and outside the isolation room, as well as with patients. The use of various ICT solutions, such as real-time video-conferencing systems or mobile robots, could enhance patient monitoring in the isolation room and improve the quality and efficiency of communication. Conclusions The changes in work tasks not only led to nurse exhaustion but also negatively impacted the quality of care. ICT solutions should be explored to minimize the time spent in the isolation room, thereby reducing the risk of infection spread. This could also enhance communication among patients, family caregivers, and healthcare professionals
