Objectives: It is clinically essential to know the location of accessory mental foramen in the mental nerve anesthesia. The aim of this study was to determine the frequency of accessory mental foramen and examining its morphometric properties. Methods: A total of 35 adult mandibles of unknown age, gender, and ethnicity were examined. The presence of accessory mental foramen of the mandible was investigated bilaterally. In cases with the accessory mental foramen, its localization, number, and distance relative to the mental foramen (...) were evaluated. Results: Eleven (15.71%) accessory mental foramens were detected in the 35 mandibles (70 sides) examined. Six (54.55%) of the accessory mental foramens were on the left side, and 5 (45.45%) were on the right side. Conclusion: Knowing the frequency and localization of the accessory mental foramen will make the mental nerve block more effective and facilitate surgical procedures. It should be kept in mind that the presence of accessory mental foramen should be considered in cases where mental nerve block applications are insufficient. (shrink)

İslam dininin kutsal kitabı olan Kur’an-ı Kerim’in Orta Çağ Hristiyan Batı dünyasında yüzyıllar boyu ön kabullerle incelendiği ve uzun polemiklere konu edildiği bilinmektedir. Kur’an’ın farklı ve nispeten daha objektif okumaları ancak Aydınlanma dönemi sürecin-de kilisenin hegemonyasının kırılması sonrasında mümkün olabilmiştir. Alman şair Jo-hann Wolfgang von Goethe (1749-1832) bu yeni perspektifin en önemli temsilcilerinden biridir. Gençlik yıllarından itibaren Kur’an ile meşgul olan Goethe, farklı meallere ve kaynaklara da müracaat ederek Kur’an hakkında zengin bir bilgi birikimine sahip olmuş-tur. Yapılacak yüzeysel bir inceleme, (...) onun Kur’an ve İslam dünyasından aldığı ilhamları meşhur Doğu-Batı Divanı’nda şiirlerine yansıttığını göstermeye yetecektir. Elinizdeki bu makalede kısaca Kur’anʼın Hristiyan Batı dünyasındaki algısı anlatılacak, ardından Goet-he’nin Kur’an ile olan meşguliyeti ortaya konulacaktır. Son bölümdeyse, Kur’an’ın Doğu-Batı Divanı’ndaki yansımalarının izi sürülecektir. (shrink)

Objective: The aim of this study is to evaluate relationship between ostiomeatal complex variations (OMC) and maxillary sinus pathologies in children and adolescents using cone-beam computed tomography (CBCT). -/- Methods: CBCT images of 72 patients (44 males and 28 females) aged 7-18 years were evaluated retrospectively. Presence of nasal septal deviation (NSD), nasal septal pneumatization (NSP), concha bullosa (CB), accessory maxillary ostium (AMO), agger nasi cell (ANC), Haller cell (HC), Onodi cell (OC), ethmoid sinusitis and maxillary sinus pathologies were investigated. (...) Maxillary sinus pathologies were classified. Correlations of OMC variations with each other, maxillary sinus pathologies and ethmoid sinusitis were investigated. Chi-square test was used to analyze relationships among variables and distribution of parameters. -/- Results: NSD was determined in 70.8%, NSP in 40.3%, ethmoid sinusitis in 75%, maxillary sinus pathology in 34.8% of images. OMC variations rates were detected as CB 31.3%, AMO 16%, ANC 16%, HC 24.3% and OC 18.8%. The most common maxillary sinus pathology was localized mucosal thickening, with a rate of 15.3% on right and 22.2% on left. Statistically significant differences were determined between almost all OMC variations with each other, and between anatomical variations in OMC with maxillary sinus pathologies except for NSP and AMO (p < 0.05). The presence of ethmoid sinusitis was more common in males (p =0.026). -/- Conclusion: Anatomical variations in OMC had no significant effect on maxillary sinus pathology except for NSP and AMO. Besides, most of anatomical variations in OMC were statistically significantly correlated with each other. CBCT visualization of these variations is important for sinonasal surgery and is an effective method in children and adolescents with low radiation dose and high image quality compared to computed tomography.

Introduction: Multiple sclerosis (MS) is an autoimmune disease that causes scar tissue in the nervous system and seriously affects the quality of life of people. Muscle weakness, spasticity and coordination problems are seen primarily in the lower extremities. Strengthening exercises improve muscle strength in people with multiple sclerosis, but there is no consensus on their effect on walking capacity. -/- Methods: To determine the relationship between gluteus maximus muscle strength, ataxia, balance and walking capacity in Multiple Sclerosis. An experimental study (...) design was applied. Gluteus maximus muscle strength was measured using a dynamometer. Walking capacity was determined by the 6-minute walk test (6MWT) and dynamic gait index (DGI). Balance was evaluated with the one-leg standing test (SLS). The severity of ataxia was measured with the International Ataxia Rating Scale (ICARS). Fatigue was evaluated with VAS and quality of life of all patients with SF36 short form. -/- Results: EDSS mean of the study = 3.39 ± 1.4; 2 men and 16 women with mean age = 37.17 ± 9.16 years were included. 6MWT, DGI, ALS, ICARS, VAS were different before and after treatment (p<0.05). There was no significant difference other than physical function and general health among the sub-parameters of SF36 (p>0.05). Correlation of muscle strength with ataxia, gait and balance was not significant (p>0.05) -/- Conclusion: In individuals with MS, the fact that the treatment program consists of modalities that include balance and sensory exercises as well as muscle strengthening exercises increases the success of rehabilitation.

Bu makalede, Milet Okulu doğa filozoflarının ontolojileri çerçevesinde töz hakkındaki görüşlerine yer verilmektedir. Buna göre, öncelikle, töz kavramının felsefi tartışmalarda neden farklı şekillerde ele alındığını açıklamak için kavramın kökeni ve çeşitli anlamlarına yönelik tespitler aktarılmaktadır. Bu tespitlerden hareketle, Thales, Anaksimandros ve Anaksimenes'in her şeyin ilk ilkesi (arkhe) arayışında ulaştıkları sonuçların töz olarak kabul edilebileceği ve onların farklı nitelikte olan tözlerinin felsefi töz kavramının çeşitli özelliklerine atıfta bulunduğu ortaya konulmaktadır. Nihai olarak, makalenin amacı Miletli filozofların töze ilişkin kavrayışlarının birbirine paralel olduğunu, (...) ancak töze atfettikleri özelliklerin farklılaştığını ve bu noktada Anaksimenes’in töz kavrayışının diğer düşünürlere oranla daha kapsayıcı olduğunu ortaya koymaktır.

Although an inverse relationship between religion and deviance is empirically well-established in the western context, previous studies on Islam and deviance conducted in non-western countries are limited. To address this gap in deviance research, we hypothesized that individual religiosity would be inversely related to deviance with the inverse relationship being more likely for ascetic than anti-ascetic or secular deviance. To test this hypothesis, we applied ordinary least squares and logistic regression methods to analyze data collected from 2,005 survey participants of (...) a Turkish public university student population. Regression results provided partial support for the hypothesis, as we found that religiosity was inversely related to both ascetic and secular deviance. The observed inverse relationship is noteworthy in that it was found in an institutionally secular, Muslim country. Implications of our findings are discussed. (shrink)

The point that is stressed by definitions of culture, which rely on its authenticity and considerations that it entails individuality (diversity), is its diversity. Being diverse and acknowledgement of authenticity of the diversity, involves forwardness in itself. Though the acknowledgement of diversity and the impression of integrity formed by the acknowledgement seem to pose a coherence, yet it bears a negative aspect internally. Despite so-called acknowledgement of diversity, coherence and integrity formation seem to be more important. Since coherence of the (...) integrity is based on measures of the seeking subject, forwardness aims to preserve things that are available or to simply fill the gaps. Hence complexity and diversity bear a negative meaning for available things. Because of centered approach which basically is putting familiar things into a closer circle while putting others aside. It brings concretization to the culture. To the extent of concretization endeavor, it leads us to study culture as belonging to a society (the privatization aim here even breaks down culture to a subculture level). Concretization of culture itself might seem as understanding and acknowledgement of culture, however, the aim for making a definition involves detaching the existent from existence forms and from the environment that it exists in. This article is to discuss, with philosophical terms, how different cultures embrace sincerity in exposing themselves while interacting with other cultures given our definitions of culture and eeking for multiculturalism. Thanks to developments in transportation and means of technology, different cultures and societies meet and interact easily. Though we have a heritage of drawing borders, these borders hardly preserve their existence. The issues under discussion have evolved from the endeavor to build a common identity-culture-society to acknowledgement of diversity and difference. (shrink)

Abstract: This article examines risks associated with the program of passive search for alien signals (Search for Extraterrestrial Intelligence, or SETI) connected with the possibility of finding of alien transmission which includes description of AI system aimed on self-replication (SETI-attack). A scenario of potential vulnerability is proposed as well as the reasons why the proportion of dangerous to harmless signals may be high. The article identifies necessary conditions for the feasibility and effectiveness of the SETI-attack: ETI existence, possibility of AI, (...) small size of the Seed AI, small speed of physical interstellar travel and large distance between civilizations. Needed additions to the SETI protocol are considered: keep the signal existence, its content and source location in secret, don’t run alien programs, jam dangerous signals, wait until creation of humanity’s own AI. In addition, scenarios in which it may be reasonable to start an alien AI (if it has been downloaded) are explored. (shrink)

Would the existence of extraterrestrial intelligent life conflict in any way with Christian belief? We identify six areas of potential conflict. If there be no conflict in any of these areas—and we argue ultimately there is not—we are confident in declaring that there is no conflict, period. This conclusion underwrites the integrity of theological explorations into the existence of ETI, which has become a topic of increasing interest among theologians in recent years.

What are the implications for human society, and for our institutions of higher learning, of the discovery of a sophisticated extraterrestrial intelligence (ETI) operating on and around Earth? This book explores this timely question from a multidisciplinary perspective. It considers scientific, philosophical, theological, and interdisciplinary ways of thinking about the question, and it represents all viewpoints on how likely it is that an ETI is already operating here on Earth. The book’s contributors represent a wide range of academic disciplines in (...) their formal training and later vocations, and, upon reflection on the book’s topic, they articulate a diverse range of insights into how ETI will impact humankind. It is safe to say that any contact or communication with ETI will not be merely a game changer for human society, but it also will be a paradigm changer. It makes sense for human beings to prepare themselves now for this important transition. (shrink)

In his article “If Loud Aliens Explain Human Earliness, Quiet Aliens are also Rare”, Robin Hanson proposes the Grabby Alien Hypothesis, which proposes that extraterrestrial civilizations (ETIs) exist outside of our observable universe and are gradually expanding to fill the universe. The existence of such grabby aliens in our future expanding to fill all available niches puts a cosmic deadline on independently originating sources of life. This cosmic cutoff offers an explanation for why human observers seem to be relatively early (...) in spacetime, why the red dwarf stars seem to be inadequate for independently originating life, and why the Fermi Paradox remains unsolved. However, we should worry about Hanson’s proposal, since the Grabby Alien Hypothesis has its own paradoxical implication, namely that most observers in most reference classes should be grabby aliens themselves (Bostrom, 2002). Thus, oddly, finding ourselves not to be grabby alien observers, it seems Hanson is beholden to explain why we are not. Some possibilities for grabby alien observer alternatives can be offered, though none are particularly explanatorily appealing. In what follows, we will 1) attempt to restate in simple terms Hanson’s assumptions, and then 2) reassemble Hanson’s arguments, showing they lead to a paradox, and 3) consider which assumptions should be rejected and at what cost.

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous country. (...) The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

This study outlines a new proposal on the creation of Islamic Anthropology on the basis of "perennialist epistemology", to use Aslan's term (2005:55). A previous proposal of this kind had been put forward by Akbar S. Ahmed in his Toward Islamic Anthropology: Definition, Dogma and Directions (1986). While Ahmed's proposed Islamic Anthropology aims at assessing and arguing with Western anthropologists over their misconceptions about Islamic societies they observe, then preparing and replying to their study in a scholarly manner by (...) "creating their own alternative scholarship" (1986:55), this author's recommended Islamic Anthropology aims at finding philosophia perennis or sophia perennis or religio perennis or "essential commonality" (Beinorius 2005:237) or "transcendent unity" (Aymard & Laude 2004:38) between Islamic, other religious and ethnic cultural manifestations, or rather, in Indonesian context, between Islamic, other religious and adat cultural manifestations. The building of Islamic Anthropology of perennialist bend in Indonesia is imperative since in the aftermath of national economic crisis and dethronement of Pres. Soeharto, Anthropology academia in Indonesia relishes the freedom of no longer having to serve the regime socio-political agenda. Post-Soeharto era of decentralization, liberalization, emancipation, and democratization provides favourable opportunity for Anthropology to set its own purely academic goals (Ramstedt 2005 :215). This new situation also enables anthropologists from diverse epistemological traditions to contribute directly to establishment of new kinds of Anthropology based on their specific epistemologies. To clarify what is meant by his perennialism-based Islamic Anthropology, the author herein elaborates the perennialist epistemology on which he bases his suggested Islamic Anthropology, explains the perennialist ontology on which the epistemology is based, delineates how to build an Islamic Anthropology based on the perennialist epistemology, and lastly exemplifies application of the perennialist method in Islamic Anthropology he proposes.

In this article, a classification of the global catastrophic risks connected with the possible existence (or non-existence) of extraterrestrial intelligence is presented. If there are no extra-terrestrial intelligences (ETIs) in our light cone, it either means that the Great Filter is behind us, and thus some kind of periodic sterilizing natural catastrophe, like a gamma-ray burst, should be given a higher probability estimate, or that the Great Filter is ahead of us, and thus a future global catastrophe is high probability. (...) If ETIs exist in our light cone, it is most likely they exist in the form of ET artificial general intelligence (ETAI). ETAI may be traveling at near-light speed as an explosive wave of intelligence in the form of some nano-mechanisms which could reach us at any moment; may send us potentially dangerous messages with AI-virus payloads; or be near or on Earth in some dormant form. This dormant form could be nanobots, which could act as berserkers, and be triggered when humans unwittingly cross some threshold. If ETIs are nearby and less advanced, they could find our messaging extra-terrestrial intelligence (METI) messages and send their “fleet” to or direct weapons toward Earth. Even extinct ETIs could have left dangerous remnants in the form of AI systems that our civilization may encounter. If our existence is a simulation, this could be run by ETIs. Even a false belief in the existence of ETIs could potentially fuel millennial sects. If humanity is the first intelligence to emerge, it may kill or prevent the existence of all future potential ETI, a different type of catastrophe. Several options to prevent catastrophic risks are connected with ETI: sending requests for help, using random strategies to escape the Fermi paradox, Great Filter prediction, or the hope that ETIs will find the remains of our extinct civilization and resurrect it.
