Construction of Hong-dae cultural district : cultural place, cultural policy and cultural politics
No full textCho M. Construction of Hong-dae cultural district : cultural place, cultural policy and cultural politics. Bielefeld (Germany): Bielefeld University; 2007.This dissertation examines how the process of creating the "Hong-dae cultural district" in Seoul has involved the mobilisation of various social groups and triggered the (re)institutionalisation of the meaning of "the cultural". It seeks to explicate how a cultural policy project can stimulate the emergence of social groups, which challenge existing policy provisions and laws and lead to the (re)institutionalisation of "Hong-dae culture". In so doing, the author will be able to simultaneously take account of the issues of agency, structure and culture by explicating the relationship between cultural policy and social change

Flexible and biodegradable electronic implants for diagnosis and treatment of brain diseases
No full text© 2021 The Author(s)In the diagnosis and treatment of brain diseases, implantable devices have immense potential for intracranial sensing of brain activity and application of controlled therapy for providing feedback to the sensing. Flexible materials are preferred for implantable devices, as they can minimise implanted device–brain tissue mechanical mismatch. Moreover, biodegradable implantable devices can reduce potential immunological side-effects. Biodegradability also helps avoid the burdensome secondary surgery for retrieving the implanted device. In this study, we reviewed recent advancements related to the use of flexible and biodegradable type of implantable devices for the diagnosis and treatment of brain diseases. Representative cases of intracranial sensing and feedback therapy are introduced, and then a brief discussion concludes the review.11Nsciescopu

Dept. of Dental Science, Graduate School, Yonsei University
(Directed by Prof. Byung Hwa Sohn, D.D.S., M.S.D., Ph.D.)
The purpose of this study was to investigate the growth changes of maxilla and
mandible and position changes of first permanent molars of growing children.
The author analyzed the data using cephalometric roentgenogram of 43 boys and 39
girls age of 6 to 11 with normal occlusion.
The obtained results were as follows
1. The eruption path of maxillary and mandibular first permanent molar
superimposed on TMANS and mandibular plane shows individual variation.
2. There was no correlation between horizontal and vertical changes of maxillary
first permanent molar, but positive correlation in mandibular first permanent
molar.
3. As the eruption, the forward changes of mandibular first permanent molar was
significantly greater than that of maxillary first permanent molar.
4. As the ages were increased, there were irregular growth changes of maxilla and
mandible.
5. Growth changes of lower anterior facial height was relatively stable
6. N-S-6 was stable after age7.

Octave-Spanning Supercontinuum Generation in Thermally Deposited As2S3 Waveguide on Wet-etched SiO2 Structure
No full textWe report octave -spanning supercontinuum generation in etch -less As2S3 film waveguide platform. The spectrum is extended from 1.05 to 2.71 p.m pumped by 45 pJ pulse energy at 1.56 p.m telecommunication wavelength. (.0 2019 The Author(s
Supercontinuum generation in As2S3 waveguides fabricated without direct etching
No full textWe report a supercontinuum generation (SCG) in a waveguide that spontaneously forms without an etching process during the deposition of a core material on a preformed SiO substructure. The mechanism of dispersion control for this new, to the best of our knowledge, type of waveguide is analyzed by numerical simulation, which results in a design rule to achieve a target dispersion profile by adjusting the substructure geometry. SCG is experimentally demonstrated with a waveguide made of As S , chalcogenide glass, which has low material absorption over the mid-IR range. A dispersion-controlled waveguide with a length of 10 mm pumped with 77 pJ pulses at a telecommunication wavelength of 1560 nm resulted in a supercontinuum that extends by more than 1.5 octaves. 2 2 3National Research Foundation of Korea (2020R1A2C1008292, 2020R1A4A2002828); Samsung Research Funding & Incubation Center of Samsung Electronics (SRFC-IT1801-03

Real-Time Temporal Dynamics of Bicistronic Expression Mediated by Internal Ribosome Entry Site and 2A Cleaving Sequence
No full textMulticistronic elements, such as the internal ribosome entry site (IRES) and 2A-like cleavage sequence, serve crucial roles in the eukaryotic ectopic expression of exogenous genes. For utilization of multicistronic elements, the cleavage efficiency and order of elements in multicistronic vectors have been investigated; however, the dynamics of multicistronic element-mediated expression remains unclear. Here, we investigated the dynamics of encephalomyocarditis virus (EMCV) IRES- and porcine teschovirus-1 2A (p2A)-mediated expression. By utilizing real-time fluorescent imaging at a minute-level resolution, we monitored the expression of fluorescent reporters bridged by either EMCV IRES or p2A in two independent cultured cell lines, HEK293 and Neuro2a. We observed significant correlations for the two fluorescent reporters in both multicistronic elements, with a higher correlation coefficient for p2A in HEK293 but similar coefficients for IRES-mediated expression and p2A-mediated expression in Neuro2a. We further analyzed the causal relationship of multicistronic elements by convergent cross mapping (CCM). CCM revealed that in all four conditions examined, the expression of the preceding gene causally affected the dynamics of the subsequent gene. As with the cross correlation, the predictive skill of p2A was higher than that of IRES in HEK293, while the predictive skills of the two multicistronic elements were indistinguishable in Neuro2a. To summarize, we report a significant temporal correlation in both EMCV IRES- and p2A-mediated expression based on the simple bicistronic vector and real-time fluorescent monitoring. The current system also provides a valuable platform to examine the dynamic aspects of expression mediated by diverse multicistronic elements under various physiological conditions.National Research Foundation of Korea (NRF) of the Ministry of Science and ICT [NRF-2017R1C1B2008775, NRF-2017R1A4A1015534, NRF-2018M3C7A1022310]; KBRI basic research program through Korea Brain Research Institute - Ministry of Science and ICT [17-BR-04]Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Breaking and Fixing VoLTE
No full textLong Term Evolution (LTE) is becoming the dominant cellular networking technology, shifting the cellular network away from its circuit-switched legacy towards a packet-switched network that resembles the Internet. To support voice calls over the LTE network, operators have introduced Voice-over-LTE (VoLTE), which dramatically changes how voice calls are handled, both from user equipment and infrastructure perspectives. We find that this dramatic shift opens up a number of new attack surfaces that have not been previously explored. To call attention to this matter, this paper presents a systematic security analysis.
Unlike the traditional call setup, the VoLTE call setup is controlled and performed at the Application Processor (AP), using the SIP over IP. A legitimate user who has control over the AP can potentially control and exploit the call setup process to establish a VoLTE channel. This combined with the legacy accounting policy (e.g., unlimited voice and the separation of data and voice) leads to a number of free data channels. In the process of unveiling the free data channels, we identify a number of additional vulnerabilities of early VoLTE implementations, which lead to serious exploits, such as caller spoofing, over-billing, and denial-of-service attacks. We identify the nature of these vulnerabilities and concrete exploits that directly result from the adoption of VoLTE. We also propose immediate countermeasures that can be employed to alleviate the problems. However, we believe that the nature of the problem calls for a more comprehensive solution that eliminates the root causes at mobile devices, mobile platforms, and the core network
