Coordination of a power system with the phasor measurement devices in real time on the load and generation sides is carried out within the context of smart grid studies. Power systems equipped with information systems in a smart grid pace with external security threats. Developing a smart grid which can resist against cyber threats is considered indispensable for the uninterrupted operation. In this study, a two-way secure communication methodology underpinned by a chaos-based encryption algorithm for PMU devices is proposed. The (...) proposed system uses the IEEE-14 busbar system on which the optimum PMU placement has been installed. The proposed hyperchaotic system-based encryption method is applied as a new security methodology among PMU devices. The success of results is evaluated by the completeness of data exchange, durations, the complexity of encryption-decryption processes, and strength of cryptography using a microcomputer-based implementation. The results show that the proposed microcomputer-based encryption algorithms can be directly embedded as encryption hardware units into PMU and PDC devices which have very fast signal processing capabilities taking into considerations the acceptable delay time for power system protection and measuring applications and quality metering applications which is 2 ms and 10 ms, respectively. While proposed algorithms can be used in TCP or UDP over IP-based IEEE C37.118, IEC 61850, and IEC 61850-90-5 communication frameworks, they can also be embedded into electronic cards, smartcards, or smart tokens which are utilized for authentication among smart grid components.

In the history of Islam, many scholars who have contributed to Islamic sciences both with their works and their thoughts have been attributed to teşeyyuʻ (being inclined to Shi'ism). Dārakutnī (d. 385/995) is one of the scholars who were subjected to this accusation. Dārakutnī, who was considered one of the leading ḥadīth reciters of his period with his strong memory and deep understanding, wrote many works showing his competence in the science of ḥadīth He was also given the title of (...) “Amīr al-mu’minīn fi’l-hadīs”, a title bestowed upon very few people. The background behind Dārakutnī’s accusation of teşeyyuʻ is that he memorized the poems of Sayyid al-Himyerî (d. 173/789), a Shiite poet. In this article, the allegation of teşeyyu' attributed to Dārakutnī has been examined and the information that constitutes the source of the said accusation against him has been examined and whether this accusation has been handled on a solid basis has been examined. As a result of the research conducted on both Dārakutnī’s own words and works and the Ahl al-Sunnah and Shia rijāl literature, it was concluded that the accusation of teşeyyu' directed against Dārakutnī was merely an allegation and was not based on a scientific basis. In the research, the information in the relevant sources was examined and an attempt was made to present the information obtained in an objective manner. (shrink)

The institutional model as delineated by classical Public Administration has limited utility for public administration in the developing countries. There are unlikely to be any uniform structural remedies foradministrative defects in those countries. Similar relationships do not have similar consequences in different contexts. An increased awareness along these lines led to the emergence of Development Administration- an effort to relate structures to goals - and Comparative Public Administration - analysis of administrative structures in their own societal contexts. The basic argument (...) of the present articles is that despite our increased sophistication on these matters the relevance in Development Administration cannot be obtained if one relies only on theoretical knowledge. It is noted that in Development Administration thinking must descend from the heights of systematic theory to the open country of praxis. (shrink)

Since the 1970s, the concepts of “lifeworld” and “everyday life” have been part of the discourse of social pedagogy and social and educational work in general. Xavier Úcar's objective in this article is to generate and communicate socio-pedagogical knowledge that helps social pedagogues to build socio-educational relationships that are more effective, more sustainable, more satisfactory, and ultimately richer in terms of both experiences and learning for participants. A conceptually oriented, nonsystematic analysis procedure was used to conduct this research. The procedure (...) involved an in-depth investigation of documents that focus on the two target areas of this study: (1) social pedagogy, and (2) lifeworld and everyday life. The results describe the theoretical background of lifeworld and everyday life, discuss the development of the perspective of “lifeworld orientation” within the framework of social pedagogy in Germany, and analyze how everyday life is understood through actions undertaken by social pedagogues. These results provide ideas for mapping the essential dimensions of everyday life from the perspective of social pedagogy. (shrink)

Interoperability across data sets is a key challenge for quantitative histopathological imaging. There is a need for an ontology that can support effective merging of pathological image data with associated clinical and demographic data. To foster organized, cross-disciplinary, information-driven collaborations in the pathological imaging field, we propose to develop an ontology to represent imaging data and methods used in pathological imaging and analysis, and call it Quantitative Histopathological Imaging Ontology – QHIO. We apply QHIO to breast cancer hot-spot detection with (...) the goal of enhancing reliability of detection by promoting the sharing of data between image analysts. (shrink)

This article is on Jean-Paul Sartre’s existentialist philosophy and his theory of art. Sartre, first of all, sets up phenomenological ontology, then founds humanist atheist existentialism. Sartre projects his theory of committed literature as his contribution to the field of philosophy of art on phenomenological ontology and humanist atheist existentialism. In the first part of this article, a brief description of the sources and grounds of Sartre’s ideas are given. In the second part, the theory of committed literature is explained. (...) Here, the most important property of Sartre’s art theory, namely Sartre’s separation of literature from plastic arts is clarified. The second part of the article is composed of four sections. In the first section of the second part, Sartre’s critique against the theory of aesthetic purity is investigated. In the second section, a relation between development of art and human freedom is set up. In the third section the difference between art of literature and plastic arts is determined. In the fourth and the last section the meaning of committed literature is defined. (shrink)

Many societies have had different tendencies in terms of belief in the historical process. The purpose of this article is to look in general terms whether the types of society, including the Arabs, in the pre-Islamic tribe and clan structuring, have experienced systems such as totemism, fetishism, naturism and animism in different forms and time periods. Likewise, it is to examine the pre-Islamic Arabs, the features that distinguish them from other types of society, and their monotheistic religions and paganism that (...) they have lived since ancient times. In our research, it was concluded that the perception of a monotheistic religion, the last representative of which was "hanif" until Islam, had spread to such an extent that it had a profound effect on the religious experiences of pre-Islamic Arabs, and therefore, the idolatry of the pre-Islamic Arabs was never independent of the degeneration of the monotheistic religion, as in Hanif. has been reached. At the same time, Hanif thought also shared the fate of ancient divine religions, and faced the pressure of paganism before the phenomenon of communion could be realized, that is, before the religious experience of Hanif could be shared by its believers with its social dimension. However, the limited historical data on both pagan worship and Hanif's religious experience is one of the difficulties of the research as a problematic issue. Another issue we question in our study is that the idolatry of the pagan Arabs who cannot be seen as different forms of worship that only worship the idol and symbolize the show of servitude to him. As a matter of fact, these idols are embodied on earth as symbols of a pantheon of gods that includes "the supreme being Allah", jinn, angels and other abstract beings. Naturally, they are also powerful and should be respected, worshiped, sacrificed, inshort, worshiped as representatives of the gods. At the same time, since they are divine beings, they are expected to fulfill any task required of a god. (shrink)

Although nature of science and nature of scientific inquiry are related to each other, they are differentiated as NOS is being more related to the product of scientific inquiry which is scientific knowledge whereas NOSI is more related to the process of SI. Lederman et al. determined eight NOSI aspects for K-16 context. In this study, a science camp was conducted to teach scientific inquiry and NOSI to 24 6th and 7th graders. The core of the program was guided inquiry (...) in nature. The children working in small groups under guidance of science advisors conducted four guided-inquiries in the nature in morning sessions on nearby plants, animals, water, and soil. NOSI aspects were made explicit during and at the end of each inquiry session. Views about scientific inquiry questionnaire was applied as pre- and post-test. The results of the study showed that children developed in all eight NOSI aspects, but higher developments were observed in “scientific investigations all begin with a question” and “there is no single scientific method,” and “explanations are developed from data and what is already known” aspects. It was concluded that the science camp program was effective in teaching NOSI. (shrink)

The sūrat al-Takāthur is one of the early Makki surahs and takes its name from the word meaning passion for multiplicity and consists of 8 verses. There are rumors that the surah descended from two tribes in Mecca, the Ansar, or the Jews, who tried to indicate their superiority by using numerical and commercial power. While doing the study, the words that serve as the key concept in the surah were scanned from competent dictionaries and possible meanings were revealed. Afterwards, (...) the main subjects of the surah were determined, and these subjects were processed in the context of the culture of tafsir, associating them with today's world. It is seen that the types of Takāthur, the sources of true knowledge, the torment in the grave and being taken into account from blessings are discussed in the Surah. The surah, which emphasizes that children, rank, property and wealth, which the Qur'an generally refers to as the ornament or livelihood of worldly life, should not be made the main target, draws attention to man's passion for multiplicity. According to the Surah, man's passion for numerical and economic multiplicity distracted him from his main task and eventually caused him to perish. Considering that the numerical and economic growth passion of individuals and societies is the cause of many wars, it is seen how appropriate this warning and result is. The surah uses the degrees of "ilme'l-yakin" and "ayne'l-yakin", which are accepted as the sources of precise and correct information, in order to comprehend the strong message given. Another issue that the commentators dwell on in the surah is “No; You will know later!” are phrases. While some commentators accept these statements as evidence for torment in the grave, others do not. Finally, the surah states that he will be questioned about all the blessings that cause a person to fall in love with numerical and economic reproduction, and that the blessings he enjoys now will cause him to go to Hell in the hereafter, and asks him to act by taking this matter into account.

This study aimed to examine the thoughts and expectations of patients receiving healthcare from their physicians and evaluate the ethical aspects of these thoughts and expectations. To determine the ethical aspects of the thoughts and expectations of patients, an open-ended question was asked on the web page of the Turkish Armed Forces (TAF) Health Care Command, which is accessible to the users of the TAF intranet system (the internet system used within TAF institutions). The participants were asked to express their (...) thoughts in their own words. A total of 804 participants answered the question by providing their input. The statements of the participants were classified separately by two public health specialists. The classification was made in accordance with the basic principles of patient rights, and they were collected under various headings including expectations about respect and care, good communication, informed consent, and fair and non-privileged distribution of healthcare services. The results show that patients tend to consider the physicians they see as solely responsible for all the negative issues that they encounter during their healthcare. This indicates that there is a need for extensive research on the underlying factors involved in the negative thoughts and feelings toward healthcare professionals in both TAF and Turkey in general.

Maxwell has shown in his field equations that electricity and magnetism, which are thought to be two separate phenomena, are in fact two distinct components of a single phenomenon. Maxwell not only developed these fundamental equations but used them to predict the existence of electromagnetic waves and to show that light is an electromagnetic wave. In this study, I researched on the emergence and effects of Maxwell's field equations using data from the history of physics. As a result of the (...) evaluation, I emphasized the revolutionary character of Maxwell's way of explaining the functioning of the universe and identified certain insufficient points. In conclusion, I tried to show that new explanations are inevitable in order to understand the universe and to show the role of mathematics in these explanations. (shrink)

This article focuses on the relationship between morality and law through the debate between William Whewell (1794-1866) and John Stuart Mill (1806-1873), two important moral philosophers of 19th century Britain. Whewell belongs to a tradition maintaining that the basic moral principles can be known intuitively through an inherent faculty such as moral sense or conscience. In the meantime, Whewell argues that the process of knowing these basic principles intuitively is not an irrational process and that the reason is active throughout (...) the whole process of knowing. In this context, the reason is the most basic concept of Whewell's system. In Whewell's system, the will of God is the highest/ultimate good. Relatedly, action in accordance with the will of God is morally right action. On the other hand, utilitarianism, to which Mill belongs, is a moral theory that determines the greatest happiness of the highest number of people as the criterion for morally right action. This theory does not include any metaphysical and theological elements, which argues that morality should be based on experience and introspection. Utilitarianism rejects the claim that there are basic moral principles that can be intuitively known. This approach of utilitarianism makes these two theories natural opponents of each other. One of the topics of the Whewell-Mill debate is the juncture of morality and law. In this context, Whewell's views on the moral-law relationship, Mill's criticism of Whewell on this issue and Whewell's responses to Mill constitute the subject of the article. The main purpose of this study, in which the comparative method is adopted, is to gain new perspectives on the relationship between morality and law. When we focus on the Whewell-Mill debate, we see that Whewell deals with the moral-law relationship on the basis of the concept of right, while Mill deals with the concept of justice. According to Whewell, it is impossible to talk about morality unless there are rights determined by law. In this regard, justice basically means compliance with the law. Like Whewell, Mill accepts that justice is not static but dynamic, and argues that only the utility can determine what just is. Mill objects to Whewell's views on three main criticial points. These are; according to Mill, Whewell first makes law the basis of morality by claiming that it is not possible to talk about morality where there are no laws. Whewell, objecting to this criticism of Mill, states that he does not make law the basis of morality; he says that he needs law to put moral principles into the practice. The second criticism of Mill is that Whewell makes laws the criterion of moral righteousness, which narrows morality down to rights and therefore to law compliance. Whewell objects to Mill, saying that moral rightness is much broader concept than legal rightness. For him, obedience to the law is only part of moral righteousness. Mill’s last criticism is that Whewell made obedience to the law a moral duty, even if it is not just. In Whewell's system, obedience to laws confirming slavery is made a moral duty. Whewell, on the other hand, admits that laws may be immoral from time to time, but states that obedience to these laws is more reasonable than disobeying them; because the problems that will arise from non-compliance with the laws are much greater. What needs to be done is to make sure that more just laws are legislated. However, according to Whewell, legislation is the duty of the jurist, not the moralist. These criticisms made by Mill against Whewell are actually criticisms that is related Mill's own system. Mill neither himself can give satisfactory answers to these criticisms. In conclusion, in the polemic between Whewell and Mill, it is possible to find other different answers of both thinkers regarding the relationship between morality and law. However, it cannot be said that these answers completely solved the problems stated above. (shrink)

We understand from the oldest sources that have reached us that according to their status, racial characteristics, culture, religion etc. people called their adressees with many different names besides their own names. The Arabic nicknames and titles, which are the main subject of our research result of this necessity. Before the formation of Islamic culture and civilization, different titles were used in all civilizations, especially in the Byzantine and Sassanid empires, for the members of the group, which were considered as (...) the elite class, apart from their names. Of course, the Arab society of jahiliyyah was also greatly influenced by his. In the political and bureaucratic structure created by the rapid spread of Islam and the interaction from different civilizations, a new naming, or rather nicknames, were made by using religious figures. This happened to such extend that the original names of many rulers remained in the shadows. The strict centralist structure of the Umayyad state required an authoritarian state administration that would not need excessive credit or definition. Therefore, the caliph did not need an extra nickname or title to define himself. At the same time, it would be appropriate to say that they never had any thoughts of praising the politicians and bureaucrats affiliated with them. The radical change in the political understanding with the Abbasid revolution also led to a great change in naming strategies. In fact, it is possible to explain the differentiation in this management approach through titles in the shortest way. The famous names of the Abbasid caliphs are nothing but nicknames. These names, which are adorned with the words of Allah, are actually an effort to show religious sensitivity to the subjects. The sensitivity in the language of diplomacy has come to the fore even more with the special divans established. The language of religion and the language of politics have been intertwined, and the caliph, who is the representative of the creator on earth, has been giving nicknames/titles around him. We see the actual situation of this practice as concrete in relation to the vassal states. During the Abbasid period, the level of relations between the states, which first emerged as semi-independent and later independent, and the caliphate differed according to time and conditions. In proportion to the political power of the Abbasid state, these heads of state were given different ranks. In this research, we try to reveal the background of the ranks given to the heads of vassal state established in the Khorasan and Transoxiana region and carrying out very important activities in the political sense. Additionally, we aim reveal to find out the political, religious and social structure of Tahirids, Saffarids, and Samanids, who are also very important in terms of Turkish history and serve as a bridge between the region and the center of the caliphate, Baghdad. We think that the subject discussed is important in order to discover the unknown aspects of the historical process in the political and bureaucratic formation of the Turkish empires established after the collapse of these three vassal states. In fact, it can be said that even today, the historical anatomy of the ranks used in terms of status determination and the arrangement of the political field in different Islamic geographies is being explored. Most importantly, in this study, we try discover the cornerstones of the communication dimension of the mawali with the Arab power. The location of the Transoxiana and Khorasan geographies before the Islamic conquests and the population fluidity accelerated by the Turkish migrations were an important factor in the political formation of the region during the Abbasid period. The historical background was taken into consideration in the titles given to the vassal state rulers. It is remarkable that the caliph gave the old Turkish title “ıhsid” to a Turkish leader of a state established in Egypt. There are many other examles such as this with regard to the vassal states in the East. The conclusion we have obtained from our study is that titles play a decisive role in the political connection between the center of the caliphate and the affiliated states. On the one hand, this regulates the balance between the center and local administrators, on the other hand, it determines the moral as well as the material rank of the sultans in the eyes of the people. In fact, the successes in the conquests led the caliphs to rank the vassal sultans with titles. This situation is a kind of password that determines the balance between the religious authority, the caliphate, and the worldly authority. (shrink)
