Analysis of nurse's ability in preventing nosocomial infections on floor 6B using the Nvivo method at RSU Royal Prima Medan 2022
Authors: Purba Deborah Angelin , Ginting Chrismis Novalinda , Wahyuni Sri
Published: August 2023

Nosocomial infection is an infection originating from a hospital caused by hospital staff or health workers during the health service process or hospital visitors. The background of this research is the lack of role of nurses in the process of preventing nosocomial infections. The purpose of this study was to explain the role of nurses in preventing nosocomial infections at RSU Royal Prima. This type of research uses a qualitative approach with in-depth interviews with informants so that they can clearly and in-depth know the role of nurses in preventing nosocomial infections at RSU Royal Prima. The results showed that nurses already know how to report to a doctor if there are signs and symptoms of infection and transmission of infectious diseases and protect against precautions while on duty at the hospital. However, there are still nurses who do not know optimally in terms of maintaining hospital cleanliness. In maintaining hand hygiene, nurses only know in terms of hand washing, the implementation is not in accordance with the procedure. In using Personal Protective Equipment, nurses know their role in terms of wearing masks and gloves, but in practice there are still nurses who have not used Personal Protective Equipment according to standards. In addition, there are obstacles for nurses in preventing nosocomial infections such as inadequate infrastructure.

Published: August 2023

The aim of this study is to determine level of arsenic in sheep‘s blood, wool and liver in Ghorveh area, city of Kurdistan provinces in Iran. The samples of blood and wool of 55 sheep, including both sexes in different age groups (<1, 1–3 and >3 years) were collected, sampling of liver also carried out from the slaughterhouse of the mentioned area. The mean concentration of arsenic in the blood, wool and liver of sheep were 10.024±7.105, 13.699±10.205 and 7.684±3.75 ppb, respectively, which blood concentration shown significant difference statistically in comparison to the normal value (P<0.05) whereas wool and liver do not show significant difference statistically (P>0.05). There is no significant correlation between arsenic concentration with age and sex (P>0.05). Arsenic concentration revealed the high level of arsenic in the environment and food in Kurdistan, which can be a serious threat to public health and other creatures.
Phenotypic differentiation among cattle populations based on biometric traits
Authors: PUNDIR R K , SINGH P K
Published: August 2023

An attempt was made to differentiate 3 cattle populations of Rajasthan state i.e. Kankrej (407), Sanchori (152) and Nari (175) by canonical discriminant analysis (CDA), a multivariate technique using 12 different biometric traits. Single trait analysis variance showed that Sanchori cows had largest size, Kankrej was intermediate and Nari was the smallest. The step-wise discriminant analysis showed that distance between hip bones, heart girth, horn length, face width, ear length, face width, horn diameter, height at withers, tail length without switch, tail length and body length were the most discriminating traits between these three cattle populations. The Mahalanobis distances between these cattle populations indicated that they are three distinct populations. The dendrogram based on the average linkage method showed that there are 2 clusters; cluster one includes Nari and Sanchori cows and cluster two Kankrej cows, clearly separated from cluster one. The individual assignment to different cattle populations by the cross-validation classification approach showed that 100% of the Kankrej cows, 98.08% of Sanchori cows and 98.98% of Nari cows were correctly assigned into their source populations. The present study revealed that the free canonical approach is proved useful and informative in differentiating between 3 cattle populations and suggested that Sanchori and Nari may be established/registers as a distinct breed.

Authors: SINGH MOHIT , SINGH RAM , MANDAL A B , SHARMA MAMTA
Published: August 2023

In the present study, the effect of supplementation of vitamin E in ochratoxin A (OTA) contaminated diet in ameliorating adverse effects of ochratoxin on biochemical parameters and immune response in broiler chickens was investigated. Day old broiler chicks (240) were divided into 6 treatment groups (T1- control (basal diet), T2 - T1 + 200 ppb OTA, T3 -T1 + 100 mg vit. E, T4 -T1 + 200 mg vit. E, T5 -T2 + 100 mg vit. E and T6 -T2 + 200 mg vit. E). Each diet was fed to 5 replicated groups of 8 birds each from 0 to 42 days of age. The blood samples were collected on 42 days of age of broilers. The total serum protein and haemoglobin (Hb) concentrations in T2 (200 ppb OTA) and T5 (200 ppb OTA + 100 mg vit. E) were lower (P<0.05) than that of control (T1) diet. The serum protein and Hb contents in group T6 was higher (P<0.05) than that of T2 but statistically similar to that of control. The serum uric acid, creatinine, alkaline phosphatase (ALP), serum glutamic oxaloacetic transferase (SGOT) and serum glutamic pyruvic transferase (SGPT) value in T2 was higher (P<0.05) than that of T1. The serum uric acid, creatinine, ALP, SGOT and SGPT value in T6 (200 ppb OTA + 200 mg vit. E) was lower (P<0.05) than that of T2 and statistically similar to that of control (T1). The CMI and HA titre value in T2 was lower (P<0.05) than that of control (T1). The CMI and HA titre value of T3 and T4 was statistically similar to that of control. The CMI value of T5 and T6 was lower (P<0.05) than control, but higher (P<0.05) than T2. The CMI of group T6 was higher (P<0.05) than T5. The HA titre value of group T5 was higher (P<0.05) than T2 and lower than T1. The HA titre value in T6 was statistically similar to that of T1, indicating that inclusion of vit. E (200 mg/kg diet) ameliorated the adverse effect of ochratoxicosis in broiler chickens. Thus, it was concluded that ochratoxin contamination at 200 ppb level in broiler diet had adverse effect on blood biochemical profile and immune response, which were restored through supplementation of vitamin E at 200 mg/kg of feed in ochratoxin contaminated diet in broiler chickens.

Published: August 2023

Hydroponics cowpea (Vigna unguiculata) (NB-4) sprouts were produced daily for 15 days in a hydroponics chamber (greenhouse) equipped with automatic sprayer irrigation of tap water. Cowpea (NB-4) with seed rate of 2.54 kg/m2 with replicates of 15 was soaked in tap water individually for 4 h.The seeds were strained and spread in the greenhouse trays. Inside the greenhouse, each replicate was allowed to grow for 9 d, after which it was harvested. The fresh yield (kg/kg seed) of the hydroponically sprouted cowpea (NB-4) increased with the advancement of growing period and remained similar and highest from day 6 (6.34) to 9 (6.63) growing period. Simultaneously, with the growth of the hydroponics cowpea sprouts, the DM content (%) decreased and remained similar and lowest from day 8 (6.91) to day 9 (6.49) growing period. The CP(%) of the hydroponics cowpea fodder was lowest on the day 1 (22.30), then increased and remained similar during seventh (30.10) to ninth (31.23) day sprouting period. The EE content increased and remained similar during day 5 (2.31%) to 8 (2.47%) of sprouting, however, it was highest on day 9 (3.22) of growth. During the growth period of the hydroponics cowpea sprouts, the CF(%) and NFE(%) had an increasing and decreasing trend and was highest and lowest, respectively, on day 9 (21.59 and 38.59). There was an increasing trend in the TA and AIA content of the hydroponics cowpea sprouts with the advancement of the growth period, which was lowest on day 1 (3.99) and highest (5.38) on day 9. It can be concluded that based on the yield and different nutrient contents, cowpea (NB-4) can be sprouted hydroponically for 6–9 days to use as feed supplement for dairy animals.
Electronic parliament as a factor of sustainable development: History and prospects
Authors: Mazur Tamara , Flogaitis Spiros
Published: August 2023

The relevance and significance of the study of the history and prospects of electronic parliamentarism as a factor of sustainable development is conditioned upon the anthropocentric vision of the idea of digitalization of the parliament. For the purpose, the authors chose to consider the system of digital tools that make up the e-parliament in the context of its role in the implementation of the Sustainable Development Goals “Peace, Justice, and Strong Institutions”. The main methods of scientific cognition, which were used when drafting the study, were the methods of content analysis, analogy, and comparison. The levels of the multi-level system of information and data security as a key element of the security of digitalization of the parliament were defined, challenges related to the legal, economic, social, and technological aspects of the process were outlined. Based on the analysis of legal acts and directly on the websites of the parliaments of countries with different democracy indices (Great Britain, Iceland, Sweden, Poland, the Czech Republic, the Baltic countries), global trends in the specified area were formulated. The author emphasized the inherent nature of certain features and the uncertainty of the consequences of digitalization of the parliament in states with various levels of democratic development and different economic indicators. It was established that the transition of parliamentarians in communication with voters from conventional communication in an offline format to an online format contributes to the implementation of openness, inclusiveness, cooperation, and participation in the political sphere. The results of the study were designed to update the issue of the need to introduce new electronic parliamentary tools for the implementation of digital democracy mechanisms in society
Criteria for distinguishing looting from other crimes: A comparative analysis
Authors: Kopotun Ihor , Murzo Yevheniia
Published: August 2023

With the beginning of the Russian-Ukrainian war, increasingly often crimes of a general criminal nature are instead qualified by Article 432 of the Criminal Code of Ukraine, where the composition of crimes is entirely different. The purpose of this study was a comprehensive analysis of the structure of the criminal offence of looting by comparing it with other crimes, as well as formulating a unified practice of understanding and qualification in the aspect of the subject of the study. According to the set purpose of the study, a complex of scientific methods was used, namely, general scientific and special ones: the method of statistical research – to analyse and compare the dynamics of committing criminal offences related to looting; dialectical – within the framework of investigating the theory and practice of contradictions related to the incorrect qualification of looting; comparative legal – in the context of analysing the positions of other scientists regarding the understanding of the essence of looting; formal logical – when defining the legal category “looting”. It was established that the need for the correct application of the specified provision is conditioned upon such circumstances as the increase in the number of cases of looting that become known from open sources of information, which are not properly registered and not investigated by law enforcement officers, which is due to the lack of experience in working with criminal offences of such specificity and complexity of their registering in the occupied territories; the need to distinguish such crime as “looting” under Ukrainian legislation from cases of robbing civilians, their living quarters, vehicles, shops, and other infrastructure for profit and satisfying one’s personal needs. The practical significance of this study lies in the fact that the main statements and conclusions can be used in methodological recommendations for the development of an algorithm for the investigation of criminal offences related to criminally illegal actions, prescribed by Article 432 of the Criminal Code of Ukraine, and are also valuable for the subjects of criminal justice in their activities to eliminate misunderstandings and different interpretations of the current legislation revealed by practice; considered when improving the legislation aimed at the prevention and fight against this type of crime, by making corresponding amendments

APROXIMACIÓN A UN MODELO CIBERNÉTICO DE INTELIGENCIA ESTRATÉGICA Y COMANDO EJECUTIVO
Authors: Levy Alberto
Published: August 2023

En los próximos años, un número creciente de empresas están destinadas a quedar obsoletas y desaparecer debido a la megacomplejidad: cambios en la demanda de los mercados finales, presión de los canales de distribución, desarrollos tecnológicos, cambios geopolíticos, saltos psico-socioculturales de los miembros de la organización, maniobras de los competidores y la creciente convergencia entre diferentes sectores industriales (por nombrar los factores más relevantes). El nivel de fricción competitiva es extremo, lo que resulta en una reducción en la capacidad de crear valor a partir de conceptos estratégicos simplistas. Es necesario abordarlos, en cambio, desde una “Teoría del Otro" que intente imaginar las maniobras posibles de los competidores. Este es el ámbito de la Inteligencia Estratégica y su vínculo recursivo con el Comando Ejecutivo, que debe preparar a los equipos humanos y a sus miembros para ser viables en escenarios tan agresivos, impredecibles e inimaginables de los que ni siquiera la Inteligencia Artificial puede brindar una anticipación confiable. El vínculo entre la Inteligencia Estratégica y el Comando Ejecutivo debe entenderse como un modelo cibernético con requisitos de morfostasis, morfogénesis y epistemología de constructivismo radical.

Published: August 2023

La determinación del valor de los ahorros fiscales y el impacto del impuesto a la renta en la valuación de empresa, depende del sistema tributario vigente en el mercado. Los efectos fiscales que implican pagos y ahorros, y, deben analizarse con el sistema tributario donde opera la firma. Los trabajos de Modigliani y Miller (1963) y Miller (1977) suponen un sistema clásico de imposición a la renta. La Organización Mundial del Comercio (OCDE) identifica siete sistemas tributarios clasificados en dos grandes grupos: integrados y clásicos.  El uso de las propuestas tradicionales para cuantificar ahorros fiscales sin analizar características del sistema, conduce a errores de especificación y de valuación de la firma. En tal sentido, el trabajo revisa los modelos existentes, particularmente el Modelo General. Seguidamente, expone las ecuaciones de valor correspondientes a los diferentes sistemas tributarios. Mediante un análisis de casos son aplicados los modelos para los sistemas clasificados por la OCDE. Se presentan resultados relacionados con el valor de la firma, errores de medición de las propuestas clásicas y las ventajas del Modelo General. Finalmente, se comparan a iguales alícuotas los efectos fiscales sobre el costo de capital,  el valor de la firma e impuestos pagados en cada sistema.

Published: August 2023

Los eventos extremos de inundaciones y sequías, asociados con el ciclo El Niño Oscilación Sur (ENOS), son fenómenos recurrentes en la Provincia del Chaco, y causan pérdidas de cosechas y de producción.  El presente trabajo tiene por objetivo evaluar los riesgos de pérdidas económicas directas en la producción de algodón, soja, maíz y girasol, generadas por eventos de sequias y de excesos hídricos. Para ello, se estima un indicador de riesgo de rendimientos de cultivos, y, mediante un análisis de correspondencia, se analiza la relación de dependencia entre los rendimientos extremos y las fases El Niño y La Niña. Finalmente se calcula las pérdidas en el Valor Bruto de la Producción (VBP) y se analiza la relación entre estas y las fases del ciclo ENOS.
Los resultados muestran que el cultivo de algodón presenta mayor frecuencia de rendimientos extremos (13 de 21 campañas, 62%), pero estos son de baja “intensidad” (máximo 38%); soja y maíz tienen rendimientos extremos con menor frecuencia, 38% y 33%, respectivamente, pero de mayor alcance (69%); y en girasol, la frecuencia es aún más baja, 29%, pero el alcance es mucho más amplio; pérdidas que llegan a alcanzar al 100% de los departamentos. Las fases La Niña estarían asociados a rendimientos extremos altos y muy altos en algodón; a extremos altos, muy altos, y a extremos bajos en soja; y a rendimientos muy altos en maíz y girasol. Las fases El Niño estarían asociados a rendimientos normales en soja y maíz, y extremadamente bajos en girasol. Los años neutros estarían asociados a rendimientos extremadamente bajos y muy bajos en algodón y extremadamente bajos en maíz.

Argentina ha demostrado en los últimos años una excesiva volatilidad económica. La literatura sugiere que diversos shocks reales y nominales pueden ser la fuente del desempeño macroeconómico, sin embargo, en este trabajo se muestra que los shocks de incertidumbre pueden explicar parte de dicha volatilidad. Para cuantificar esto, se estima un modelo de vectores autoregresivos estructural (SVAR) imponiendo restricción de signos y los resultados muestran que los shocks de incertidumbre son importantes para explicar las tasas de variación de la producción y la inversión en Argentina.

Robust Fingerprint of Privacy-Preserving Location Trajectories
Authors: Jiang Yuzhou , Yilmaz Emre , Ayday Erman
Published: August 2023

Location-based services have brought significant convenience to people in their daily lives, and trajectory data are also in high demand. However, directly releasing those data raises privacy and liability (e.g., due to unauthorized distribution of such datasets) concerns since location data contain users' sensitive information, e.g., regular moving patterns and favorite spots. To address this, we propose a novel fingerprinting scheme that simultaneously identifies unauthorized redistribution of location trajectory datasets and provides differential privacy guarantees for shared data. Observing data utility degradation due to differentially private mechanisms, we introduce a utility-focused post-processing scheme to regain spatio-temporal correlations between points in a location trajectory. We further integrate this post-processing scheme into our fingerprinting scheme as a sampling method. The proposed fingerprinting scheme alleviates the degradation in the utility of the shared dataset due to the noise introduced by differentially private mechanisms (i.e., adds the fingerprint by preserving the publicly known statistics of the data). Meanwhile, it does not violate differential privacy throughout the entire process due to immunity to post-processing, a fundamental property of differential privacy. Our proposed fingerprinting scheme is robust against known and well-studied attacks against a fingerprinting scheme including random flipping attacks, correlation-based flipping attacks, and collusions among multiple parties, making it difficult for the attackers to infer the fingerprint codes and avoid accusation. Through experiments on two real-life location trajectory datasets and two synthetic ones, we show that our scheme achieves high fingerprint robustness and outperforms existing approaches. Furthermore, the proposed fingerprinting scheme increases data utility for differentially private datasets, which is beneficial to data analyzers.
Track You: A Deep Dive into Safety Alerts for Apple AirTags
Authors: Shafqat Narmeen , Gerzon Nicole , Van Nortwick Maggie , Sun Victor , Mislove Alan , Ranganathan Aanjhan
Published: August 2023

Bluetooth-based item trackers have sparked apprehension over their potential misuse in harmful stalking and privacy violations. In response, manufacturers have implemented safety alerts to notify victims of extended tracking by unknown item trackers. In this study, we specifically investigate the anti-stalking mechanism of Apple's AirTag. We identify and analyze potential triggers of safety alerts that have not been examined in previous research, such as the local time, the victim's device model, AirTag's battery life, and the distance between the AirTag and the victim's device. Furthermore, we demonstrate a novel possibility of developing a stealthy cloned AirTag capable of tracking victims directly on the Find My app while circumventing safety alerts on the victim’s device. Our experiments demonstrate that, despite regular updates to the public key and MAC address, our cloned AirTag can provide real-time location updates even with a four months old key, thereby highlighting the challenges in designing a robust anti-stalking framework. Furthermore, we propose practical solutions to mitigate stalking risks from cloned AirTags and enhance the existing anti-stalking safeguards for AirTags. These suggestions seek to provide a foundation for similar Bluetooth-based item trackers to improve their anti-stalking protections while ensuring optimal tracking efficiency. We conducted rigorous experiments to validate our findings, ensuring their accuracy and reliability. Our evaluation highlights that safety alerts take over 8 hours to appear during the day and are more prompt during the night, particularly after 11 pm.
Attacks on Encrypted Response-Hiding Range Search Schemes in Multiple Dimensions
Authors: Markatou Evangelia Anna , Falzon Francesca , Espiritu Zachary , Tamassia Roberto
Published: August 2023

In this work, we present the first database reconstruction attacks against response-hiding private range search schemes on encrypted databases of arbitrary dimensions. Falzon et al. (VLDB 2022) present a number of range-supporting schemes on arbitrary dimensions exhibiting different security and efficiency trade-offs. Additionally, they characterize a form of leakage, structure pattern leakage, also present in many one-dimensional schemes e.g., Demertzis et al. (SIGMOD 2016) and Faber et al. (ESORICS 2015). We present the first systematic study of this leakage and attack a broad collection of schemes, including schemes that allow the responses to contain false-positives (often considered the gold standard in security). We characterize the information theoretic limitations of a passive persistent adversary. Our work shows that for range queries, structure pattern leakage can be as vulnerable to attacks as access pattern leakage. We give a comprehensive evaluation of our attacks with a complexity analysis, a prototype implementation, and an experimental assessment on real-world datasets.
Exploring the Privacy Risks of Adversarial VR Game Design
Authors: Nair Vivek , Munilla Garrido Gonzalo , Song Dawn , O'Brien James
Published: August 2023

Fifty study participants playtested an innocent-looking "escape room" game in virtual reality (VR). Within just a few minutes, an adversarial program had accurately inferred over 25 of their personal data attributes, from anthropometrics like height and wingspan to demographics like age and gender. As notoriously data-hungry companies become increasingly involved in VR development, this experimental scenario may soon represent a typical VR user experience. Since the Cambridge Analytica scandal of 2018, adversarially-designed gamified elements have been known to constitute a significant privacy threat in conventional social platforms. In this work, we present a case study of how metaverse environments can similarly be adversarially constructed to covertly infer dozens of personal data attributes from seemingly-anonymous users. While existing VR privacy research largely focuses on passive observation, we argue that because individuals subconsciously reveal personal information via their motion in response to specific stimuli, active attacks pose an outsized risk in VR environments.
Your DRM Can Watch You Too: Exploring the Privacy Implications of Browsers (mis)Implementations of Widevine EME
Authors: Patat Gwendal , Sabt Mohamed , Fouque Pierre-Alain
Published: August 2023

Thanks to HTML5, users can now view videos on Web browsers without installing plug-ins or relying on specific devices. In 2017, W3C published Encrypted Media Extensions (EME) as the first official Web standard for Digital Rights Management (DRM), with the overarching goal of allowing seamless integration of DRM systems on browsers. EME has prompted numerous voices of dissent with respect to the inadequate protection of users. Of particular interest, privacy concerns were articulated, especially that DRM systems inherently require uniquely identifying information on users' devices to control content distribution better. Despite this anecdotal evidence, we lack a comprehensive overview of how browsers have supported EME in practice and what privacy implications are caused by their implementations. In this paper, we fill this gap by investigating privacy leakage caused by EME relying on proprietary and closed-source DRM systems. We focus on Google Widevine because of its versatility and wide adoption. We conduct empirical experiments to show that browsers diverge when complying EME privacy guidelines, which might undermine users' privacy. For instance, we find that many browsers gladly give away the identifying Widevine Client ID with no or little explicit consent from users. Moreover, we characterize the privacy risks of users tracking when browsers miss applying EME guidelines regarding privacy. Because of being closed-source, our work involves reverse engineering to dissect the contents of EME messages as instantiated by Widevine. Finally, we implement EME Track, a tool that automatically exploits bad Widevine-based implementations to break privacy.

The Complex Roots of the Second Eritrea- Ethiopia War: Re-examining the Causes
Authors: Redie Bereketeab
Published: August 2023

The article highlights some of the embedded plausible causes of the war that are quite often glossed over. It argues that at the centre of the conflict stand different perceptions of history, identity, as well as claims and counterclaims of state rights, decolonisation process, and nation-state formation. Beyond the minor border skirmishes of May 1998, the contested interpretation of history and identity formation, and the concomitant search for a separate identity and sovereignty, on one hand, and denial of that separate identity and sovereignty, on the other, explain the Eritrea-Ethiopia conflict. In that sense the Eritrea-Ethiopia conflict will be found to revolve around the status of Eritrean independence. Moreover two sets of the conflict – Tigray-Eritrea and Ethiopia-Eritrea – have further complicated the search for settlement of the conflict. The first step towards finding a lasting solution that would normalise relations between the two countries would be Ethiopia’s definitive and unconditional recognition and acceptance of separate Eritrean identity and sovereignty, including its colonial boundaries. Both the people of Tigray, and Ethiopia as a whole, need to accept this reality. Secondly, Ethiopia’s legitimate interest should be addressed in a manner that will not undermine Eritrea’s sovereignty. Only then will Ethiopia’s need to have access to the sea find lasting and amicable solution acceptable to both sides.

Published: August 2023

Mechanical neck pain (MNP) in the second most common disability among healthcare workers. The main objective of this study was to compare the effects of dry needling (DN) and transcutaneous electrical nerve stimulation (TENS) for the management of MNP among healthcare workers. A single blind RCT (
n = 30) was conducted at the Neuro Counsel Clinic, Islamabad. Simple convenient sampling techniques were used to recruit participants of age 20-50 years who had no comorbidity of any kind. Two equal groups were made. Group A received DN for ×1/day for 2 weeks and Group B received TENS at the rate of ×2/day for 2 weeks. Data were evaluated on the basis of Numeric Pain Rating Scale (NPRS) and Neck Disability Index (NDI) score. Prepost data were analyzed for within group (Wilcoxon rank test) and between groups (Mann–Whitney
U test). The level of significance was kept at
P < 0.05. The mean ± standard deviation (SD) of age in Group A was 33.87 ± 8.18 while in Group B it was 33.67 ± 7.60. Wilcoxon rank test revealed that both techniques are effective for within-group analysis (
P < 0.001). Mann–Whitney U test revealed that both techniques showed no significant results on NPRS score as
P > 0.05 but the NDI score revealed that there is a significant difference between groups (
P < 0.05). On the basis of results, it is concluded that DN is more effective when compared to TENS for disability management in MNP sufferers.
"MINEIRINHO" E A NECROPOLÍTICA ESTATAL
Authors: Santos Júnior Rivaldo Frias dos
Published: August 2023

O presente texto, apresentado na forma de ensaio, traça um paralelo entre a crônica "Mineirinho", de Clarice Lispector – uma das autoras de maior renome do Brasil –  e algumas doutrinas que veem o criminoso como verdadeiro inimigo da sociedade, a exemplo do direito penal do inimigo, de Günther Jakobs, e da necropolítica, de Achille Mbembe. O texto não tem por objetivo detalhar referidas teorias, que servem, apenas, de embasamento doutrinário, para amparar as ideias colacionadas por Clarice Lispector, a fim de apontar que as classes mais abastadas buscam utilizar o aparato estatal, com o desiderato de lhes garantir o sentimento de paz e tranquilidade, às custas da exclusão de determinados grupos. Sob um enfoque humanista, buscou-se fazer um contraponto entre as indagações da crônica "Mineirinho" e elementos teóricos que embasam o direito penal do inimigo e a necropolítica.
EDITORIAL: PARA OUTRAS CRÍTICAS DA VIOLÊNCIA
Authors: Rodrigues Carla , Pinho Isabela
Published: August 2023

Patrice Maniglier define como “verdadeiro momento filosófico” aquilo a que o pensamento nos reivindica sempre a retornar. Considerando “Para uma crítica da violência”, de Walter Benjamin, como um desses “verdadeiros momentos filosóficos”, pretendemos debater a atualidade da Crítica e das questões ali colocadas. A relação aporética entre violência e poder, implicada na ambivalência do termo Gewalt, a distinção entre direito e justiça, e, sobretudo, o diálogo com o jurista alemão Carl Schmitt acerca do estado de exceção, mediado por Giorgio Agamben, auxiliam a pensar outras críticas da violência que ajudem a refletir sobre nosso tempo de agora.

Authors: Oh Dong-Geun
Published: August 2023

The Korean Decimal Classification (KDC) and Nippon Decimal Classification (NDC) are national classification systems of Korea and Japan. They have been used widely in many libraries of each country and maintained successfully by each national library associations of Korean Library Association (KLA) and Japan Library Association (JLA). This study compares the general characteristics of these two national classification systems using their latest editions of KDC 6 and NDC 10. After reviewing the former research, their origins, general history and development, and usages were briefly compared. Various aspects including classification by discipline, not by subjects, decimal expansion of the classes using pure notations of Arabic, hierarchical structure, and mnemonics quality are checked for both systems. Results of the comparative analyses of major auxiliary tables, main classes and 100 divisions of schedules of two systems are suggested one by one with special regards to Dewey Decimal Classification (DDC). The analyses focus on the differences between both systems as well as the characteristics which reflect the local situations of both countries. It suggests some ideas for future developments and research based on the results of their strengths and weaknesses.
