Steganographic tools available in the internet and other commercial steganographic tools are preferred than customized steganographic tools developed from scratch by unlawful groups. Hence a clue regarding the steganographic tool deployed in the covert communication process can save time for the steganalyst in the crucial active steganalysis phase. Signature analysis can lead to success in targeted steganalysis but tool detection needs to be taken forward from a point with a suspicious stego image in hand with no additional details available. In such scenarios, statistical steganalysis comes to rescue but with issues to be addressed like huge dimensionality of feature sets and complex ensemble classifiers. This work accomplishes tool detection with a specific composite feature set identified to distinguish one stego tool from the others with a weighted decision function to enhance the role of the specific feature set when it votes for a particular class. A tool detection accuracy of 85.25% has been achieved simultaneously addressing feature set dimensionality and complexity of ensemble classifiers and a comparison with a benchmark procedure has been made

Steganography hides the data within a media file in an imperceptible way. Steganalysis exposes steganography by using detection measures. Traditionally, Steganalysis revealed steganography by targeting perceptible and statistical properties which results in developing secure steganography schemes. In this work, we target LSB image steganography by using entropy and joint entropy metrics for steganalysis. First, the Embedded image is processed for feature extraction then analyzed by entropy and joint entropy with their corresponding original image. Second, SVM and Ensemble classifiers are trained according to the analysis results. The decision of classifiers discriminates cover image from stego image. This scheme is further applied on attacked stego image for checking detection reliability. Performance evaluation of proposed scheme is conducted over grayscale image datasets. We analyzed LSB embedded images by Comparing information gain from entropy and joint entropy metrics. Results conclude that entropy of the suspected image is more preserving than joint entropy. As before histogram attack, detection rate with entropy metric is 70% and 98% with joint entropy metric. However after an attack, entropy metric ends with 30% detection rate while joint entropy metric gives 93% detection rate. Therefore, joint entropy proves to be better steganalysis measure with 93% detection accuracy and less false alarms with varying hiding ratio.

Both the authors’ previous experience and the devoted literature highlight the particular role of teacher-student communication for the quality of graduates’ professional development and education. The research presented herein is based on a sociological survey conducted in a large university from north-west Romania, on more than 600 Economics Master’s students.The chief goal of our research is to determine efficient ways to improve the student training provided by the master programmes in Economics, by means of a better stimulation on the part of the teachers, a more efficient teacher – student communication, a better quality of the teaching materials employed and a greater relevance of the educational content for the particular area of specialisation pursued.After an initial review of the material resulted from the sociological survey, we continued to analyse the results in relation to the tiers of the communication process, the role of groups in the learning process and of the education process in the development of emotional intelligence.Within the current phase of our study, the underlying hypotheses are:(1) The training of Economics and Business Administration students provides them with opportunities of professional specialisation, while developing skills and abilities useful in everyday life.(2) The students’ training in Economics also entails an implicit educational process, which supports the development of their emotional intelligence.(3) Multiculturalism bears manifold benefits, both in terms of specialist professional training and on graduates’ attitudes and behaviour in the social life.This study allowed us to validate the hypotheses and to draw some interesting conclusions for the education of students enrolled in the university surveyed.

The scientific publication is aimed at exploring the communicative aspects of tourism, its value impact on humans, substantiating the peculiarities of the development of international tourism as a way to formation of cross-cultural tolerance. The article accentuates on the cultural values and value characterizations of international tourism, the role of the communicative culture of the individual as the main link in the concept of the theoretical model of universal human values, the importance of adherence to the principles of tolerance, which are becoming increasingly important in the modern world in the context of globalization of the economy, development of communications, growth of mobility, integration, interdependence and transformation of social cultures. The approaches to analyzing tourism as a social and cultural phenomenon are systematized, the stages of the communication process are distinguished. The author analyzes the content of the most significant documents in the sphere of international tourism adopted with the participation of the World Tourist Organization, which emphasizes the need to adhere to tolerant forms of communication. The focus is placed on the role of international organizations in strengthening cultural ties between peoples, mutual enrichment of cultures as a result of tourist exchange, observance of the principles of tolerance. On the way to the application in practice of establishing intercultural communications in international tourism, the article substantiates effectiveness of such methods as: introduction of an adequate system of acculturation, which involves such types of communication ties as integration, assimilation, division, marginalization at the levels of emotions, actions and cognition; creation of such conditions by the host party, which would contribute to increasing the level of satisfaction of tourists by establishing a constant exchange of information, maintaining feedback, disseminating content among visitors regarding the prospects for the development of tourist infrastructure of the host country.

Abstract PurposeThis study sought to analyze the predicting role of dosimetric parameters for nonclassic radiation-induced liver disease (RILD) after helical tomotherapy (HT) in Child-Pugh (CP) class A primary liver carcinoma (PLC) patients.Patients and methodsA total number of 71 CP class A PLC patients treated with HT from June 2011 to June 2015 were retrospectively reviewed. Clinical characteristics and dose-volume histogram (DVH) were recorded, and liver functions were followed up for 4 months after radiotherapy.ResultsIn all, 57 patients (80.3%) were male, and 14 (19.7%) were female, with a median age of 53 years. The mean gross tumor volume (GTV) was 226.8 cm3. A median dose of 55.0 Gy was delivered by HT with a median fraction size of 2.6 Gy. Twelve patients (16.9%) were diagnosed with nonclassic RILD. The mean dose to normal liver (MDTNL) and the percentage of total liver volume receiving more than 25 - 35 Gy irradiations (V25 - V35) were related to nonclassic RILD. MDTNL showed the highest AUC (0.705, p=0.026). The optimal cut-off value of MDTNL was 21.3 Gy with a sensitivity, specificity and accuracy of 83.3%, 62.7% and 67.6%, respectively. The tolerable volume percentages for DVH were less than: V25 of 42.3%, V30 of 33.9%, and V35 of 28.3%.ConclusionThis study suggests that MDTNL, V25, V30 and V35 are dosimetric predictors for nonclassic RILD in CP class A PLC patients. MDTNL < 21.3Gy, V25 < 42.3%, V30 < 33.9%, and V35 < 28.3% may be used to optimize HT planning.

Lipoteichoic Acids

In Bacillus subtilis, the cell is protected from the environment by a cell envelope, which comprises of layers of peptidoglycan that maintain the cell shape and anionic teichoic acids polymers whose biological function remains unclear. In B. subtilis, loss of all Class A Penicillin-Binding Proteins (aPBPs) which function in peptidoglycan synthesis is conditionally lethal. Here we show that this lethality is associated with an alteration of the lipoteichoic acids (LTA) and the accumulation of the major autolysin LytE in the cell wall. We provide the first evidence that the length and abundance of LTA acts to regulate the cellular level of LytE. Importantly, we identify a novel function for the aminoacyl-phosphatidylglycerol synthase MprF which acts to modulate LTA biosynthesis in B. subtilis and in the pathogen Staphylococcus aureus. This finding has implications for our understanding of antimicrobial peptide resistance (particularly daptomycin) in clinically relevant bacteria and MprF-associated virulence in pathogens, such as methicillin resistant S. aureus.

The Many

The language system is susceptible to the many changes that occur in society and the consciousness of its members. Language units can be motivated by taboos – a phenomenon that causes a person to abandon the use of some language units and replace them with others that are more suitable for this communicative situation. Such a replacement is due to mental rejection, emotional discomfort, in fact, cognitive dissonance, which is born as a result of various objective and subjective factors. The presence in the human mind of a fideistic attitude to the word is a psychological reality. Therefore, the use of replacement words as a result of a certain mental discomfort has become the subject of research not only for linguists, but also for scientists who deal with issues of culture, religion, ethnography, and especially psychology. Some sources that we used to write an article are not so much of a linguistic nature, but rather of a psycholinguistic one. At the same time, scientists note that consciously or unconsciously, but a person always feels a greater role of associative connections between a word and a named subject. The purpose of the article is to study language units motivated by ancient remnants, and to determine the role of euphemisms in the communication process. It is these “soft” expressions that make speech more pleasant, one that protects the psyche and aesthetic feelings of a person.

In the era of Society 5.0, the role of communication technology was further enhanced so that it made it easier for humans in various aspects, such as economic, social, cultural, educational, health, business, and so on. However, the sophistication of information and communication technology causes interpersonal to interact less rarely face to face and face to face because it is more comfortable interacting through cyberspace through social media. This research was conducted to illustrate how social communication from understanding anxiety in the digital age. In conducting interactions, each individual can experience communication fears where individuals tend to experience anxiety because too much information is received. The group can be one of the very positive spheres of communication. The object of this research is Basmala members, who have various backgrounds as members of Islamic spiritual groups who uphold religious values. This research uses a qualitative research method with an ethnomethodology type that looks at how the disclosure of reality in people's lives and how individuals receive, learn, apply information provided in the community. Basmala is an Islamic spiritual organization whose members are students. As a religious organization where the culture and activities of the organization also have characteristics that can lead to the basic rules of religion that are expected to familiarize its members to deal with differences in the communication process to overcome the causes of communication apprehension

The general purpose of this research is the examination of the role of the leader in the institutional communication process in TRNC primary schools. While conducting the research, principals and deputy principals, who are administrators in primary schools, were accepted as leaders in schools. At this point, it has been tried to determine how teachers perceive corporate communication in TRNC primary schools and whether their administrators show a leading role in terms of communication skills. Among the most important results of the research; Primary school teachers with a bachelor's degree had a more positive attitude towards the communication skills of their administrators than primary school teachers with a master's degree. Most of the teachers (69.4%) participating in our study stated that the most important feature that a leader should have is "effective communication skills".
