Published: December 2020

Matrix-assisted laser desorption–ionization/time of flight mass spectrometry (MALDI-TOF MS) has been widely implemented for the rapid identification of microorganisms. Although most bacteria, yeasts and filamentous fungi can be accurately identified with this method, some closely related species still represent a challenge for MALDI-TOF MS. In this study, two MALDI-TOF-based approaches were applied for discrimination at the species-level of isolates belonging to the Cryptococcus neoformans complex, previously characterized by Amplified Fragment Length Polymorphism (AFLP) and sequencing of the ITS1-5.8S-ITS2 region: (i) an expanded database was built with 26 isolates from the main Cryptococcus species found in our setting (C. neoformans, C. deneoformans and AFLP3 interspecies hybrids) and (ii) peak analysis and data modeling were applied to the protein spectra of the analyzed Cryptococcus isolates. The implementation of the in-house database did not allow for the discrimination of the interspecies hybrids. However, the performance of peak analysis with the application of supervised classifiers (partial least squares-discriminant analysis and support vector machine) in a two-step analysis allowed for the 96.95% and 96.55% correct discrimination of C. neoformans from the interspecies hybrids, respectively. In addition, PCA analysis prior to support vector machine (SVM) provided 98.45% correct discrimination of the three analyzed species in a one-step analysis. This novel method is cost-efficient, rapid and user-friendly. The procedure can also be automatized for an optimized implementation in the laboratory routine.

Published: December 2020

Soil organic carbon (SOC) is an important indicator of soil quality and directly determines soil fertility. Hence, understanding its spatial distribution and controlling factors is necessary for efficient and sustainable soil nutrient management. In this study, machine learning algorithms including artificial neural network (ANN), support vector machine (SVM), cubist regression, random forests (RF), and multiple linear regression (MLR) were chosen for advancing the prediction of SOC. A total of sixty (n = 60) soil samples were collected within the research area at 30 cm soil depth and measured for SOC content using the Walkley–Black method. From these samples, 80% were used for model training and 21 auxiliary data were included as predictors. The predictors include effective cation exchange capacity (ECEC), base saturation (BS), calcium to magnesium ratio (Ca_Mg), potassium to magnesium ratio (K_Mg), potassium to calcium ratio (K_Ca), elevation, plan curvature, total catchment area, channel network base level, topographic wetness index, clay index, iron index, normalized difference build-up index (NDBI), ratio vegetation index (RVI), soil adjusted vegetation index (SAVI), normalized difference vegetation index (NDVI), normalized difference moisture index (NDMI) and land surface temperature (LST). Mean absolute error (MAE), root-mean-square error (RMSE) and R2 were used to determine the model performance. The result showed the mean SOC to be 1.62% with a coefficient of variation (CV) of 47%. The best performing model was RF (R2 = 0.68) followed by the cubist model (R2 = 0.51), SVM (R2 = 0.36), ANN (R2 = 0.36) and MLR (R2 = 0.17). The soil nutrient indicators, topographic wetness index and total catchment area were considered an indicator for spatial prediction of SOC in flat homogenous topography. Future studies should include other auxiliary predictors (e.g., soil physical and chemical properties, and lithological data) as well as cover a broader range of soil types to improve model performance.
Synthesis of European Union Biorefinery Supply Networks Considering Sustainability Objectives
Authors: Potrč Sanja , Čuček Lidija , Martin Mariano , Kravanja Zdravko
Published: December 2020

Increasing the use of renewable energy sources is one of the most important goals of energy policies in several countries to build a sustainable energy future. This contribution proposes the synthesis of a biorefinery supply network for a case study of the European Union (EU-27) under several scenarios based on a mathematical programming approach. Several biomass and waste sources, such as grains, waste oils, and lignocellulosics, are proposed to be utilized, and various biofuels including first, second, and third generations are produced such as bioethanol, green gasoline, biodiesel, Fischer Tropsch (FT) diesel, and hydrogen. The aim of this study is to evaluate the capabilities of EU-27 countries to be able to meet the Renewable Energy Directive (RED II) target regarding the share of renewable energy in the transport sector by 2030 in each Member State while not compromising the current production of food. A generic mathematical model has been developed for the multi-period optimization of a biorefinery supply network with the objective of maximizing sustainability profit. The solutions obtained show that biomass and waste are promising raw materials to reach and go beyond the EU’s renewable energy target in the transport sector for the year 2030. However, some countries would need to provide additional subsidies for their companies to achieve at least a non-negative economic performance of biofuel production.
Research Ethics, Open Science and CRIS
Authors: Schöpfel Joachim , Azeroual Otmane , Jungbauer-Gans Monika
Published: December 2020

The purpose of this paper is to analyze how current research information systems (CRIS) take into account ethical issues, especially in the environment of open science. The analysis is based on a review of the literature on research information management, CRIS, open science and research ethics. The paper provides a framework for the assessment of CRIS on two levels: are CRIS (= their data model, format, functionalities, etc.) compliant with ethical requirements from the research community, funding bodies, government, etc., i.e., can they appropriately process data on research ethics (protocols, misconduct, etc.), and which are the ethical issues of the development, implementation and usage of CRIS? What is the impact of new ethical requirements from the open science movement, such as integrity or transparency? Can CRIS be considered as ethical infrastructures or “infraethics”? Concluding this analysis, the paper proposes an empirical approach for further investigation of this topic. The originality of the paper is that there are very few studies so far that assess the implications of research ethics and open science on the CRIS.

Vaccines can have heterologous effects on the immune system, i.e., effects other than triggering an immune response against the disease targeted by the vaccine. We investigated whether monoclonal antibodies (mAbs) specific for tetanus could cross-react with Chlamydia and confer heterologous protection against chlamydial infection. The capability of two tetanus-specific mAbs, namely mAb26 and mAb51, to prevent chlamydial infection has been assessed: (i) in vitro, by performing a neutralization assay using human conjunctival epithelial (HCjE) cells infected with Chlamydia trachomatis serovar B, and (ii) in vivo, by using a guinea pig model of Chlamydiacaviae-induced inclusion conjunctivitis. The mAb26 has been superior in comparison with mAb51 in the prevention of chlamydial infection in HCjE cells. The mAb26 has conferred ≈40% inhibition of the infection, compared to less than 5% inhibition in the presence of the mAb51. In vivo, mAb26 significantly diminished ocular pathology intensity in guinea pigs infected with C. caviae compared to either the mAb51-treated or sham-treated guinea pigs. Our data provide insights that tetanus immunization generates antibodies which induce heterologous chlamydial immunity and promote protection beyond the intended target pathogen.

ВІДСУТНІСТЬ: ТЕОРЕТИЧНА ЗНАЧУЩІСТЬ ПОНЯТТЯ ДЛЯ КОГНІТИВНИХ ДОСЛІДЖЕНЬ
Authors: Радчук Ольга Вячеславовна
Published: December 2020

У статті розглянуто поняття «відсутність» як важливе та необхідне поняття розумової діяльності людини, що усвідомлюється нею протягом усього життя. Поняття «відсутність» належить до таких базових абстрактних понять, що відіграють значну роль в концептуальній системі мови і мають важливе соціально-культурне значення. Концептуальна система будь-якого індивіда формується на основі сприйняття навколишнього світу й передбачає осягнення ним реалій цього світу в опозиції наявність vs відсутність. Оволодіння мовою, в основі якої також закаладені бінарні опозиції, дозволяє людині номінувати абстрактні поняття. Апперцепція як розумова операція, в процесі якої відбувається закріплене досвідом вторинне сприйняття, впливає на появу нових вербальних реалізацій вже сформованого поняття. Показано, що репрезентації поняття «відсутність» з’являються як наслідок розширення значень слів, метафоризації, виникнення граматичних форм, зміни або трансформації їх лексичного вираження. Автором цієї публікації обґрунтовується можливість лінгвокогнітивного осмислення та опису вербальних засобів вираження поняття «відсутність» з опорою на теорію прототипів американського психолога Елеонори Рош. Використання метода інтерпретації розширює потенціал когнітивного аналізу мовних репрезентацій поняття «відсутність». У статті робиться акцент на те, що відображене у свідомості людини уявлення про поняття «відсутність» має лексичну та граматичну об’єктивацію, яка є вторинною по відношенню до прототипу і представлена ізоморфними засобами мови. Незважаючи на те, що проблема вивчення абстрактних понять, до яких належить і поняття «відсутність», не є новою в лінгвістиці, тенденції сучасного мовознавства дозволять представити систему мову в координатах наявність vs відсутність як когнитивно обумовлених. Теоретичне осмислення поняття «відсутність» у цьому аспекті має велику перспективу.

Authors: Bello Hashim Sabo
Published: December 2020

This paper aimed to study the linkage between business firms’ actions and their resultant social costs on the environment in Nigeria. The report also attempted to provides a broad view of businesses and their resulting actions on the earth as they operate within contemporary Nigerian society. The sampling method adopted for this study was the stratified random sampling technique. The instrument used for data analysis was Chi-square (X2), adopted for hypothesis testing. A total number of 287 questionnaires were returned and considered out of the 300 questionnaires that were distributed. Data obtained was analyzed with the inferential statistical technique. Pearson Chi-square was employed to test each hypothesis at a 95 percent confidence level. Results were analyzed through Pearson Chi-square and hypotheses tested using chi-square statistics at 0.05 level of significance. SPSS version 21 was used for linear-by-linear association in hypotheses testing, assumptions establishing a linear relationship of variables were met, and error terms independence was conducted. Therefore, the study believed that if business firms are allowed to pollute the environment, the result is a rise in waste and numerous environmental consequences. Consequently, society as a whole is hurt as its overall social welfare declines. This study, therefore, recommended that the business firms should always make considerable strides in improving the performance of their products, with a strong focus on enhancing environmental efficiency with a long-term aim for zero-emission of vehicles.

Published: December 2020

In this paper, the investigator indicates the emotional intelligence plays an important role in life and contributes to the personal and social development of an individual. There is something beyond the intellectual capacity, which determines the success of a person. A survey of the study of emotional intelligence of the higher secondary school teachers should be analyzed and the investigator has launched the investigation. The sample was limited to 350 higher secondary school teachers only. The study was restricted to higher secondary Teachers only. The study was restricted to Chengalpattu Educational District only. Only the survey method is used to collect data. The Emotional Intelligence Inventory tool was used in the study. The tool was designed and developed by Thomas Alexander (2004). The investigator used the ‘test-retest’ method in establishing the reliability of the tool on emotional intelligence. The responses of both the test and retest were scored and the Correlation Coefficient of 0.74 was found between the test and retest. The means score value of male teachers 55.15 and the means score value of female teachers is 56.64. The table value 1.96 is lesser than the calculated value t value. There is no significant difference between male and female higher secondary school Teachers in their Emotional Intelligence. Hence the null hypothesis is accepted. Teachers also should have proper training in developing their Emotional Intelligence and in improving their Social attachment.

A REPORT ON STEM CELLS AND THEIR APPLICATIONS
Authors: R Shantha A
Published: December 2020

Stem cells are the building blocks of life. They have remarkable potential to regenerate and develop into many different cell types in the body during early life and growth. They are also a class of undifferentiated cells that are able to be differentiated into specialized cells types. Stem cells are characterized by certain features such as totipotency, pluripotency, multipotency, oligopotent and unipotency. The history of stem cell research had an embryonic beginning in the mid 1800s with the discovery that few cells could generate other cells. In the 1900s the first stem cells were discovered when it was found that cells generate blood cells. Nowadays, stem cell therapy is under research and till now, a very few stem cell therapies have been regarded as safe and successful. It is also found that stem cell therapy cast a number of side effects too. The cost of the procedure too is expensive and is not easily affordable.

Published: December 2020

A preocupação dos consumidores em adquirem produtos de melhor qualidade, fez aumentar a demanda por produtos orgânicos que fossem mais saudáveis, mas a bovinocultura de leite no Brasil ainda não conseguiu se adequar a essa exigência e em muitas propriedades os antibióticos ainda são usados de forma indiscriminada e uma menor parcela utiliza a homeopatia. Entretanto, a eficácia dos medicamentos homeopáticos ainda hoje é duvidosa, sendo alvo de estudos em vários países. O objetivo dessa revisão foi abordar os últimos estudos homeopáticos na criação de bovinos no Brasil a fim de verificar a eficiência de uso do medicamento. Os defensores da homeopatia afirmam que a falta de conhecimento apropriado do médico veterinário junto com outros entraves de manejo é a causa da baixa eficácia do medicamento, enquanto para outros autores ela não apresentaria resultado nenhum. As pesquisas no campo homeopático carecem de mais investigação, de novas publicações e de divulgação.

Authors: Mousa Wisam H. , Hussein Fawziea M. , Faraj Johain J.
Published: December 2020

Latent heat storage using phase change materials (PCMs) is one of the most effective methods to store solar energy, and it can significantly reduce area for solar collectors. PCMs are isothermal in nature, and thus offer higher density energy storage and the ability to operate in a variable range of temperature conditions. In this paper, experimental study has been conducted to evaluate the effectiveness of the solar thermal storage system based on the energy and exergy analysis. Barium Hydroxide Octahydrate (BHO) and Sodium Acetate Trihydrate (SAT) were used as PCMs inside multi-capsule system arranged in series based on their melting temperatures. These two salts never being used together in a multi capsule solar storage system before. The capsules were charged by three water flow rates of 0.5 LPM, 1 LPM and 1.5 LPM that comes from a parabolic trough collector. The experimental results showed that the maximum energy and exergy storage of 139.38 kJ and 17.15 kJ, respectively were obtained from 1 LPM. In other hand, the maximum system energy and exergy efficiencies of 64.82 % and 14.99 %, respectively were obtained from the use of 1.5 LPM.

Authors: Ballini Andrea , Signorini Luca , Inchingolo Alessio Danilo , Saini Rajiv , Gnoni Antonio , Scacco Salvatore , Cantore Stefania , Dipalma Gianna , Inchingolo Francesco , Santacroce Luigi
Published: December 2020

BACKGROUND: Probiotics are living microorganisms that confer a health benefit when administered in adequate amounts. There is evidence in the current literature about the importance of probiotic use in pregnancy. The early supplementation of probiotics in the perinatal and postnatal periods seems to have a positive impact on the overall mother’s health and future health of infants.
AIM: Our pilot study aimed to test the ability of specific probiotics strains in combination with the kiwi-unique enzyme actinidin to improve the availability of folic acid in 20 pregnant women.
METHODS: We investigate 20 pregnant women in early (4–10 weeks) (6 patients), intermedium (11–20 weeks) (6 patients), and late (21–30 weeks) (8 patients) pregnancy.
RESULTS: Our findings show that the tested formula promotes increased concentration of serum folate in women’s blood and contributes to the control of blood sugar and body weight, regardless of the gestational period (early, intermediate or late).
CONCLUSIONS: Our data support the main results reported in the scientific literature about the importance of probiotics intake in pregnancy.

En 1905 se cumplía el tercer centenario de la publicación de El ingenioso hidalgo don Quijote de la Mancha, compuesto por Miguel de Cervantes Saavedra. Después de las experiencias de otras celebraciones en el último cuarto del siglo XIX, en particular la de Calderón en 1881, algunos intelectuales españoles proponen una conmemoración grandiosa y espectacular para el tercer centenario del Quijote, idea que retoman los políticos de Madrid. En este artículo vamos a explorar el contexto nacionalista, político y cultural de la propuesta de celebración, pero sobre todo vamos a estudiar cómo es recibida esa propuesta en una nacionalidad histórica como Galicia.
La pluralidad lingüística en la novela helenizante posterior al Persiles
Authors: Losada Palenzuela José Luis
Published: December 2020

La presencia o mención de lenguas extranjeras en una obra literaria es un recurso ficcional que se remonta a la literatura clásica griega. Cervantes lo introduce en su novela póstuma Persiles (1617), inspirándose en Las etiópicas de Heliodoro. Este artículo se centra en dos novelas helenizantes posteriores, Semprilis y Genorodano (1629) y Eustorgio y Clorilene (1629) para interrogarlas críticamente sobre la pluralidad de lenguas y la supuesta dependencia de sus modelos literarios. Hemos optado por el enfoque narratológico definido como glotoliteratura, que nos permite modelar los diálogos entre personajes dependiendo de cómo las referencias a una lengua extranjera interactúan entre los niveles de la historia y el discurso. Concluiremos considerando que estas novelas son principalmente glotodiegéticas y usan esta instancia para reforzar la verosimilitud, relacionándolo de forma directa a la tradición de los manuales de educación de príncipes.
El tercer hombre. Juan Baptista Piñero y los orígenes de la ruptura spinoziana
Authors: Schreiber Markus
Published: December 2020

A mediados del sigl XVII, en la comunidad sefardita de Ámsterdam se conocieron el joven Spinoza y el médico Juan de Prado. Israël S. Révah consideró el encuentro como el impulso inicial a una ruptura. Según el investigador francés, el cristiano nuevo Prado decisivamente influenció al futuro filósofo holandés y provocó el paso de este a la heterodoxia. Además, Révah en el criptojudaísmo ibérico vio los «orígenes de la ruptura spinoziana», tanto más cuanto que descubrió que estaba involucrado en el asunto un tercer hombre. Este Juan Piñero, que asimismo tenía un trasfondo judío, según un testimonio de la época a su vez empujó a Juan de Prado a la heterodoxia. Solo unas recientes investigaciones permiten la reconstrucción parcial de su vida extraordinaria, que refleja la crisis intelectual de ciertos círculos académicos en la España del siglo XVII.

Upon further screening of the studies' methodologies and results, 16 studies describing art education implemented with medical students and 12 studies describing art education implemented with residents were included for final review.

Results

Various methods of art education exist, including Visual Thinking Strategies (VTS), rigorous curricula, and unstructured roundtable discussions with art curators or artistically minded clinicians. Studies range in duration, art media, and type of analysis.

Conclusions

There has been an increasing effort to incorporate fine art education into medical training, primarily to enhance visual perception skills and empathy. Although there is limited research on its efficacy, and wide variations in study methodologies exist, results consistently indicate that participants find the incorporation of art into curricula beneficial. Further research analyzing which methodologies are most likely to yield statistically and clinically significant improvements in visual perception and empathy may lead to increased utilization of this teaching method.

Published: December 2020

Background

Videoconference interviews (VCIs) are increasingly being used in the selection process of residency program candidates across a number of medical specialties, but nevertheless remain an underutilized approach, particularly in the field of primary care.

Objective

This retrospective data review with cost analysis explores financial and acceptability outcomes of VCI implementation over a 9-year period.

Methods

VCIs were incorporated into the recruitment process at a community-based academic family medicine residency program in 2011, whereby suitable candidates were selected for VCIs after Electronic Residency Application Service (ERAS) application review. Based on the outcome of VCI, candidates were invited via a structured interview tool for a subsequent in-person interviews to determine final rank decisions. Costs of the interview process were tracked, as well as perceptions of VCIs.

Results

VCI implementation over 9 years demonstrated a median 48% reduction of in-person interviews—or 95 applicants eliminated out of a total 195 VCIs performed. This represents a mean annual direct cost savings estimated at $9,154, equating to a 55% reduction in allocated program costs, in addition to indirect cost savings to both applicants and the program.

Conclusions

Compared to exclusively in-person interviewing, the utilization of VCIs is potentially more cost-effective for residency programs and candidates, while creating a more personal experience for applicants early in the recruitment process. Limited data of acceptability among faculty and candidates is generally favorable but remains mixed.
Wildlife trafficking under the lens of international law: a threat to the peace or a serious transnational crime?
Authors: Staiano Fulvia
Published: December 2020

On 16 September 2019, the United Nations General Assembly Resolution 73/343 on tackling illicit trafficking in wildlife reiterated the concept whereby wildlife trafficking constitutes a serious threat not only to the world's biodiversity and ecosystems but also to socio-economic and political stability and to the rule of law. Because of the transnational character of the illicit trade in protected species and because this activity is often carried out by organised criminal groups, any strategy of prevention and repression of wildlife trafficking should entail an effective cooperation between States within an international legal framework. Against this background, this article reflects on the ways in which international law has dealt with wildlife trafficking so far, and on the potential of different international law sources to provide States with effective tools to manage the risks posed by this transnational organised crime. To answer these questions, this article focuses on two main fields of enquiry. First, it considers the characterisation of wildlife trafficking as a threat to the peace within the framework of Chapter VII of the Charter of the United Nations by the United Nations Security Council in Resolutions 2134 (2014) and 2136 (2014), reflecting on the possibility to expand such a qualification outwith the context of specific internal conflicts and the activities of armed groups. Second, the article assesses the effectiveness of such an approach and its eventual added value in the light of the international legal framework already applicable to wildlife trafficking. To do so, it enquires on whether the United Nations Convention against Transnational Organized Crime, in synergy with the Convention on International Trade in Endangered Species of Wild Fauna and Flora, can provide States Parties with an appropriate and sufficient framework to tackle the global threats posed by wildlife trafficking.
Treaty withdrawal and recalcitrant States
Authors: Crampin Joseph
Published: December 2020

The recent prevalence of high-profile unilateral treaty withdrawals raises broader questions over trust in treaty-making. Given the foundational importance of trust in treaties to international law, these withdrawals present risks to the international legal order generally. The issue for international law is how it can regulate treaty withdrawal in a way that preserves trust in the international legal system. The problem of trust is twofold. If international law adopts too permissive a stance towards unilateral withdrawal, then this will undermine trust in the binding force of treaties: pacta sunt servanda. If it is too restrictive, it will undermine the authority of international law, since it will result in situations in which recalcitrant States (ie States which have decided no longer to comply with their obligations) disobey, and are seen to disobey, their obligations. The paper seeks to explore this tension that underlies the regulation of treaty withdrawal. First, it analyses historical approaches to the problem, and, second, how the Vienna Convention on the Law of Treaties has sought to resolve it. It then examines how the principle is and can be used to achieve a balance between integrity and authority that can assist international law in regulating withdrawal and recalcitrance in a manner that preserves trust in treaty-making.

The Link Between Amitriptyline and Movement Disorders: Clinical Profile and Outcome
Authors: Rissardo Jamir Pitton , Caprara Ana Letícia Fornari
Published: December 2020

Introduction: Amitriptyline (AMT) is a tricyclic antidepressant. In this review, we evaluate the clinical and epidemiological profile, pathological mechanisms and management of AMT-associated movement disorders. Materials and Methods: A search for relevant reports in 6 databases was performed. Studies that reported patients developed only ataxia or tremor after AMT use were excluded. Results: A total of 48 reports on 200 cases were found. AMT-associated movement disorders included myoclonus (n = 26), dyskinesia (n = 11), dystonia (n = 8), stutter (n = 5), akathisia (n = 3) and restless legs syndrome (n = 1). For less well-defined cases, 99 patients had dyskinesia, 19 had psychomotor disturbances, 3 had myoclonus, 11 had dystonia, 12 had Parkinsonism and 1 each had akathisia and extrapyramidal symptoms. Mean and standard deviation (SD) and median ages were 45.40 years (SD 16.78) and 40 years (range 3.7–82 years), respectively. Over half were women (58.13%) and the most common indication was depression. Mean and median AMT doses were 126 mg (SD 128.76) and 75 mg (range 15–800 mg), respectively. In 68% of patients, onset of movement disorders was <1 month; time from AMT withdrawal to complete recovery was <1 month in 70% of cases. A weak negative linear correlation (r = −0.0904) was found between onset of movement disorders and AMT dose. AMT withdrawal was the most common treatment. Conclusion: Amitriptyline is associated with various movement disorders, particularly myoclonus, dystonia and dyskinesias. Stutters and restless legs syndrome are some of the less common associations. Ann Acad Med Singapore 2020;49:236–51 Key words: Akathisia, Drug-induced, Dyskinesia, Dystonia, Myoclonus

Published: December 2020

“Fenomena anarki” telah mempengaruhi kebanyakan negara untuk memberikan tumpuan dan perhatian terhadap pembangunan Angkatan ketenteraan bagi menjamin keselamatan untuk tujuan kelangsungan hidup. Manakala merujukkan kepada teori neo-realisme, teori ini mengatakan dilema keselamatan sebagai situasi yang sentiasa ada ancaman yang cuba untuk menggugat keselamatan negara mahupun ianya dari bentuk unsur ancaman tradisional mahupun dari unsur dari ancaman bukan dari tradisional. Akibat dari senario keselamatan dan sifat anarki dalam sistem antarabangsa, keadaan ini akan menyebabkan negara perlu bergantung pada diri sendiri untuk kelangsungan hidup. Ini merujuk kepada konsep self help atau self reliance di mana setiap negara mempunyai kepentingan negara mereka tersendiri dalam meneruskan kelangsungan hidup dalam sistem antarabangsa. Melihat dari sudut Angkatan Tentera Malaysia (ATM,) perspektif pembangunan dan pemodenan ATM semasa era Perang Dingin dan Pasca Perang Dingin ternyata mempunyai perubahan yang signifikan di mana pembangunan ATM sebelum tahun 1990 lebih bersifat konvensional dan pasca Perang Dingin memperlihatkan pembangunan ATM bersifat lebih strategik.
Privacy Preserved Centralized Model for Counter Terrorism

Privacy preservation is an important aspect in field of counter terrorism. In the present scenario terrorist attacks are biggest problem for the mankind and whole world is under constant threat from these well-planned, sophisticated and coordinated terrorist operations. Now every country is focusing for counter terrorism. Government agencies are collecting the data from various sources and using that data to connect the dots to detect the terrorist group’s activities and prevent the peoples from terrorist attacks. There are some chances that information may be misused by agencies. Different countries are having government agencies which are dealing with the counter terrorism but they are not sharing the data with each other because they don’t want to disclose sensitive data. Alone a country can’t fight against the terrorism. In this paper we are proposing a model so that these agencies can share the information without violation of the privacy.
