A tetrabenzotriazaporphyrin based organic thin film transistor: Comparison with a device of the phthalocyanine analogue
The characteristics of bottom-gate bottom-contact organic thin film field-effect transistors (OTFTs) with 70 nm thick films of solution processed non-peripherally octahexyl-substituted nickel tetrabenzo triazaporphyrin (6NiTBTAP) molecules as active layers on silicon substrates are experimentally studied and the results are compared with the similary configured transistors using the corresponding nickel phthalocyanine (6NiPc) compound. 6NiTBTAP transistors are found to exhibit improved performance over 6NiPc transistors in terms of greater saturation hole mobility, two orders of magnitude higher on/off ratio and lower threshold voltage. This enhanced performance of 6NiTBTAP OTFTs over 6NiPc devices is attributed to improved surface morphology and large grain size of the active 6NiTBTAP film

The massification and widespread of the available tools on Internet contributes togive shape and movement to the contemporary social and political life.The variety of information and communication possibilities converges in the formation of groups and movements with shared interests and identities. In this context, in the Republic of Korea, feminist groups have emerged and proliferated promoting their demands in a quickly, anonymous and simultaneous way and were nourished by the wide possibilities offered by the cyberspace.The objective of this paper is to analyze the circumstances that motivated the conformation of these feminist groups on the web, defined under the conceptual framework of cyberfeminism, its characteristics and the consequences of its actions at a cultural and political level. This information allows us to outline the possibilities of its future development.The analysis dimensions include: the member?s characteristics, the collaboration?s types, the topics of interest, the action?s modalities, and the positioning with respect to the LGBT community.We consider that cyberfeminism has gained considerably social importance in South Korea and has influenced public opinion, also affecting the establishment of public policy agenda.The methodological approach, of qualitative nature, is nourished by previous ownresearch, specialized literature, and information collected/gathered from IT tools thatprovide/allow the analysis of our object of study. This paper considers contextual variables, such as the internet expansion and the feminism history in the country, in order to analyze the structuration of the feminist movement online.The general results achieved about cyberfeminism in Korea are focus on the member's characteristic, the types of collaboration between its members, the topics of interest, the modality of action and their positioning with respect to the demands of the LGBT community in the feminist struggle. Based on the outcomes of the investigation, it concludes with recommendationson how the South Korean feminism can influence society and promote public demonstrations that can result in changes in public policies. It also reflects on the intervention of online groups and the gender dynamics on the internet, which are strongly shaped by globalization.Fil: Bavoleo, Bárbara Inés. Universidad Nacional de La Plata.

On the feasibility of collaborative green data center ecosystems
The increasing awareness of the impact of the IT sector on the environment, together with economic factors, have fueled many research efforts to reduce the energy expenditure of data centers. Recent work proposes to achieve additional energy savings by exploiting, in concert with customers, service workloads and to reduce data centers’ carbon footprints by adopting demand-response mechanisms between data centers and their energy providers. In this paper, we debate about the incentives that customers and data centers can have to adopt such measures and propose a new service type and pricing scheme that is economically attractive and technically realizable. Simulation results based on real measurements confirm that our scheme can achieve additional energy savings while preserving service performance and the interests of data centers and customers.Peer ReviewedPostprint (author's final draft
High-mobility solution-processed copper phthalocyanine-based organic field-effect transistors
© 2011 National Institute for Materials ScienceSolution-processed films of 1,4,8,11,15,18,22,25-octakis(hexyl) copper phthalocyanine (CuPc6) were utilized as an active semiconducting layer in the fabrication of organic field-effect transistors (OFETs) in the bottom-gate configurations using chemical vapour deposited silicon dioxide (SiO2) as gate dielectrics. The surface treatment of the gate dielectric with a self-assembled monolayer of octadecyltrichlorosilane (OTS) resulted in values of 4×10−2 cm2 V−1 s−1 and 106 for saturation mobility and on/off current ratio, respectively. This improvement was accompanied by a shift in the threshold voltage from 3V for untreated devices to −2V for OTS treated devices. The trap density at the interface between the gate dielectric and semiconductor decreased by about one order of magnitude after the surface treatment. The transistors with the OTS treated gate dielectrics were more stable over a 30-day period in air than untreated ones.Technology Strategy Board, UK (Project No: TP/6/EPH/6/S/K2536J)
A study comparing the change in drug utilization pattern in medical intensive care unit of a tertiary care hospital in seven years
Background: Medical intensive care unit is a type of intensive care unit that takes care of a range of medical illnesses with patients who are seriously ill and/or suffer from severe chronic illnesses. These patients are usually prescribed multiple drugs. Use of antimicrobial agents and injectable medications in setting of MICU is high as compared with other class of drugs and other hospital settings respectively. Periodic evaluation of drug utilization pattern needs to be done to enable suitable modifications in prescription of drugs to increase the therapeutic benefit and decrease the adverse effects. There could be changes in drug utilization pattern due to changes in disease pattern, development of newer drugs, resistance to antimicrobial agents. Hence comparison of past and present data needs to be done to find out the changes that occurred in drug utilization pattern over the years.
Methods: Data was collected from June 2021 to Dec 2021 for prospective arm and June 2014 to December 2014 for retrospective arm was obtained from MICU of tertiary care hospital and Medical Record Department. Drug utilization pattern was analysed and compared with appropriate statistical tests.
Results: Most common cause of MICU admission was infective diseases (71% and 67% respectively in retrospective and prospective arm). The drug prescribed frequently was pantoprazole and antimicrobial was ceftriaxone in both the study arms. Half of the drugs were prescribed by generic names in both arms.
Conclusions: There was no change observed in drug utilization pattern and disease pattern in patients admitted to medical intensive care unit over the years in our institute
The civil organizations of the Korean diaspora and its implications for the public diplomacy of South Korea: a comparative study of Argentina and Mexico
The present paper tries to analyze the actions of civil organizations of the Korean diasporas in Argentina, a non APEC country, and Mexico, an APEC country, in order to determine its potential to constitute an effective diaspora diplomacy and their influence in the conformation of South Korea's soft power. It will also examine the possibilities to increase cooperation between diaspora organizations and the South Korean Government, with the aim to promote and improve its public diplomacy.
To understand the role of diaspora civil organization in the development of South Korean diplomacy, first we must consider the history of South Korea's relations with both nations and the characteristics of immigration in each country. In addition for the theoretical frame we will take the conceptualization of soft power and public diplomacy.Instituto de Relaciones Internacionale
Forensic Tools in Comparison: An Assessment of Performance Across Different Parameters
Computer forensics is a crucial field that
involves the collection, preservation, and analysis of
digital evidence. Forensic tools play a vital role in this
process, aiding investigators in extracting, analyzing, and
interpreting data from diverse digital devices. With the
increasing complexity of digital devices and the surge in
digital data, selecting the appropriate forensic tool has
become paramount. This study evaluates and contrasts
different free forensic tools with an emphasis on network
examination, data analysis, and password cracking. The
evaluation considers variables such platform support, file
system support, imaging capabilities, data-driven
features, reporting capabilities, hash type support, attack
types, resource utilization, and pattern matching
capabilities. The results of this comparison research are
an informative resource for forensic professionals seeking
to choose the best tool for their specific requirements.
Notably, the data analysis capabilities of Autopsy, FTK
Imager, and ProDiscover Basic displayed unique
strengths and limitations for data analysis. Due to its
robust hash type support and effective administration of
resources, John the Ripper and Hashcat emerged as
reasonable options for password cracking. The study
also recommends Wireshark for network analysis
because of its intuitive user interface, substantial packet
analysis tools, and flexible multi-platform compatibility
with other protocols. Nevertheless, is acknowledged that
the ultimate choice on a forensic tool should be tailored to
the distinct requirements and constraints of each

Las relaciones diplomáticas entre Corea del Sur y Argentina: “los primeros acercamientos”
El último trabajo realiza un recorrido histórico para dar cuenta del inicio de las relaciones diplomáticas entre la República de Corea y la República Argentina y su autora es Desiree Nair Chaure. En sus páginas se detallan los primeros acercamientos que datan del siglo XIX, con una Corea aún unida; la tenue relación durante el período colonial a través del dominador: Japón; y el rol de Estados Unidos, luego de la división, como intermediario. Hacia el final, Chaure destaca que la posición de nuestro país con respecto a Corea del Sur se correspondió con las características del orden internacional del momento y con las políticas de las distintas presidencias que, según sostiene la autora, supeditaron su accionar con Asia a los vínculos que mantenían con Europa y Estados Unidos.Facultad de Ciencias Jurídicas y Sociale
Reclamando derechos: las problemáticas del colectivo LGBT en Corea del Sur
En la sociedad coreana la homosexualidad ha sido descripta como una característica o fenómeno occidental, parte de una cultura extranjera y por ende contraria a los valores nacionales de una cultura hetero-normativa, anclada en la familia patriarcal.
A partir de la década del ’80, con el fin de la dictadura militar y el arribo de la democracia comenzaron a surgir movimientos en pos de los derechos sociales y de sectores marginados históricamente, como las mujeres, los discapacitados, los inmigrantes, los refugiados norcoreanos y el colectivo LGBT (lesbianas, gays, bisexuales, transgénero). El desarrollo del movimiento LGBT no hubiese sido posible sin éstos cambios socio económicos y la mayor participación ciudadana.
En la actualidad el colectivo LGBT se enfrenta al estigma y la hostilidad de la sociedad, lo que ha comenzado una batalla en pos de sus derechos civiles como la no discriminación, el matrimonio igualitario y posibilidad de adopción, junto con los privilegios informales como la visibilización y la aceptación social.
El presente trabajo pretende analizar la situación de las personas LGBT en Corea del Sur, en los distintos sectores, desde el familiar y el educativo, hasta el militar. Una vez contextualizada la realidad actual pasaremos a describir el desarrollo histórico del movimiento y las organizaciones LGBT, para finalmente conocer los actores principales que influencian la toma de decisiones sobre la disminución o incremento de los derechos de las minorías sexuales.Centro de Estudios Coreano
Las organizaciones civiles de la diáspora coreana y sus implicancias en la diplomacia pública de Corea del Sur : Estudio comparativo de Argentina y México
Corea del Sur posee relaciones estables con los países latinoamericanos desde el fin de la Guerra de Corea y la consolidación de la República. Los lazos no son sólo políticos, económicos y culturales sino que también están vinculados a la migración.
La República de Corea cuenta con una importante diáspora en el exterior, conformada por corrientes migratorias que viajaron en distintos periodos históricos. En Latinoamérica los países que recibieron mayor cantidad de inmigrantes de origen coreano fueron México, Brasil y Argentina. Las comunidades crecieron y comenzaron a diseñar un sistema institucional a través de sus propias asociaciones civiles, lo que brindó una estructura al grupo migratorio y estableció formas de inserción en la sociedad receptora.
Considerando que actualmente Corea del Sur se encuentra en un proceso de posicionamiento internacional como un poder medio y como puente entre los países del Este Asiático y América Latina y el Caribe, ha promovido la diplomacia pública como elemento primordial de su agenda externa. La diplomacia pública refiere a las relaciones entre actores no estatales como las organizaciones, empresas e individuos.
Es en este escenario las diásporas y sus organizaciones civiles han ganado importancia, dada su capacidad de actuar como nexo entre el gobierno surcoreano y las sociedades receptoras. Son mediadores que facilitan la comunicación entre sociedades, ayudando a cambiar las percepciones y de-construir los estereotipos culturales. Por lo tanto, son capaces de implementar las políticas del gobierno surcoreano en las sociedades receptoras. Estas características son esenciales para la creación de un poder blando eficiente por medio de la diplomacia pública.
El presente trabajo intenta analizar el accionar de las organizaciones civiles de las comunidades migrantes coreanas de Argentina, un país no miembro de APEC, y México, un país miembro de APEC, a fin de determinar su potencialidad para constituir una diplomacia de la diáspora efectiva y su influencia en la conformación del poder blando de Corea del Sur. Asimismo, se examinarán las posibilidades de incrementar la cooperación entre las organizaciones de la diáspora y el gobierno surcoreano, con el objetivo de impulsar y mejorar su diplomacia pública.
Para comprender la función de las organizaciones civiles de la diáspora en el desarrollo de la diplomacia surcoreana, debemos primeramente considerar la historia de las relaciones de Corea del Sur con ambas naciones y las características de la inmigración en cada país. Mientras que como marco teórico tomaremos la conceptualización del soft power y la diplomacia pública.Instituto de Relaciones Internacionale
