ARCHAELOGICAL RESEARCH IN THE TOWN OF MALYN, ZHYTOMYR REGION, IN 2017
Authors: Iievliev M. M. , Petrauskas A. V. , Tymoshenko V. I.
Published: February 2020

The first archaeological excavations at the Malyn ancient settlement had been initiated in 1878 by V. B. Antonovych. In the 20th century, the site has been explored by such outstanding scientists as P. M. Tretiakov, M. P. Kuchera, B. A. Zvizdetskyi. On the basis of the found artifacts, the site has been attributed as one of the earliest town settlements of the Eastern Slavs, and the discovered materials have been used to generate the concept of the early development of the towns in the East Slavonic area. Starting from 2016, the expedition of the Institute of Archaeology of the National Academy of Science of Ukraine regularly explores the site to investigate the fundamental issues of the early Slavonic towns in Eastern Europe genesis. During the field season of 2017, scientists discovered the remains of the defense constructions dating back to the earliest period of the site formation. The new data which enable to characterize the settlement surroundings has become an important result of the research in 2017. The artifacts discovered at the surrounding areas of the site indicate that culture layers of all the neighboring grounds available for settling (except for the flood lands of the Irsha river) are synchronous to those found at the settlement.
NEW SITES OF THE Хth—ХVІІІth CENTURIES IN KYIV (materials to the archaeological map)
Authors: Koziuba V. K.
Published: February 2020

62 archeological sites officially registered on the territory of Kyiv, 23 of which are of national, others — of local value. Half of these objects are architectural monuments or individual buildings (brick-burning furnaces, wooden water pipes, etc.). These sites are mostly located in the central historic part of the city. More common types of archaeological sites — hillforts, settlements, burial grounds. At the beginning of the XXIth century 76 sites of these types were known in the territory of Kyiv, of which only a few are with protected status now.

Since 2011, the author has conducted archaeological surveys in the city. Their purpose is to inspect the places of known archaeological sites and search for new ones. During this time, 78 sites were inspected, of which 61 were discovered for the first time. Among these open sites 27 dated to the Xth—XVIIIth centuries or contain finds of this time. 13 sites existed in epoch of Old Rus’ (Xth—XIIIth centuries). Accordingly, today 72 sites of this period, 4 settlements, 38 settlements, 10 burial mounds and 4 ground cemetery, 8 monasteries, 7 caves and 1 fortification rempart are registered in Kyiv.

Pottery of the second half of the XIIIth—XVIIth centuries was found at 10 sites. Magority of settlements dated to the early modern time — they were villages and farms around Kyiv. Their study allows us to find out in detail the extensive system of settlement at the Kyiv outskirts in this period and the active economic use of the latter.

A fortification rempart which has a length of 2.9 km was also inspected on the southern outskirts of the city. Its height is generally 0.2—0.5 m, width — up to 10 m. This fortification is believed to have been emerged at the turn of the Xth—XIth centuries in order to protect Kyiv from the attacks of nomads.

The discovery and study of new archaeological sites of the Middle Ages and early modern times allows us to explore the peculiarities of the emergence and development of settlement structures around one of the largest urban centers of Central and Eastern Europe, increases the number of sources on the historical urbanism of Kyiv, contributes to the memorial component of the socio-cultural development of the capital Of Ukraine.
SOURCES FOR INVESTIGATION FISHERY IN DUBNO IN XVI—XVIII cc.
Authors: Pshenichniy Ju. L.
Published: February 2020

Fishery took important place in economic and social development of Dubno in XVI—XVIII cc. There were two large ponds around Dubno in that period. Also they are well-known from historical sources as Surmycky pond and Ivansky pond. Fishery tools, which were found during archeological investigations in Dubno testify about methods of fishing, which were used by the population of the town. They are led and clay sinkers for the nets, iron fishing spears and spud, copper tackle. The fish remains from Dubno castle and Spaso-Preobrazhensky monastery belonging to eight fish species (pike, roach, indeterminate carp fish, sturgeon, common rudd, common bream, european catfish, european perch). These two prosperous centers had obviously the largest sizes of cached fishes.
«BUDINIA OR SCYTHIA?» THE ETHNIC AND CULTURAL BELONGING OF THE MIDDLE DON POPULATION DURING 5th—4th centuries BC
Authors: Guliaev V. I.
Published: February 2020

For over half a century (since the end of the 1950s), the Scythology has been discussing the location of the Scythian and non-scythian tribes mentioned by Herodotus on a geographical map. After the Scythian-Sarmatian conference in 1952 and the report of B. N. Grakov and A. I. Melyukova, most of archaeologists supported the idea that only the Black Sea steppe belonged to the Scythians, and non-scythian peoples and tribes inhabited the forest-steppe regions of the Northern Black Sea region. In this regard monuments on the Middle Don dated V—IV centuries BC began to be considered Budinia, belonging to the Budinians and Gelonians. P. D. Lieberov interpreted the Budinians as Finno-Ugric tribes. Archaeological research of the last decades (including the widespread use of the methods of the natural sciences) made it possible to revise this idea and return to the M. I. Rostovtsev and A. I. Terenozhkin point of view about the existence of a single large Scythia covering in the VII—IV centuries BC all the Northern Pontic (steppe and forest-steppe) from the Danube to the Don.
ON THE BEGINNING OF THE EARLY IRON AGE IN THE TERRITORY OF MIDDLE DON BASIN
Authors: Medvedev A. P. , Berestnev R. S.
Published: February 2020

The article is devoted to the characterization of pre-Scythian time monuments in the forest-steppe course of the Don. The authors come to the conclusion about the regional specificity of the process of cultural genesis in this territory at the beginning of the early Iron Age.

The authors analyze the new treasure of Novocherkassk type. It was opened in 2016 in the Podgorensky district of the Voronezh region. This treasure includes psalms, hatchet, metal plates, bracelet-like rings, spearheads. In inventory, it is close to the pre-Scythian burials in the forest-steppe Ukraine (Butenki, Kvitki). Obviously, the population that left the treasure penetrated into the territory of the Middle Don region from the steppes between the Dnieper and Ciscaucasia — the place where the Cimmerian culture was formed in the 9th century. Objects close to the Proto-Meotian, Novocherkassk complexes, their diversity show this process.

It remains an open question about the relationship in the studied region of the funerary monuments of Novocherkassk type and Middle-Don mounds of the Scythian time.
MIGRATION FLOWS IN THE SOUTH OF WEST SIBERIAN PLANE DURING THE LATE BRONZE AGE TO IRON AGE TRANSITION
Authors: Molodin V. I.
Published: February 2020

The article is dedicated to anniversary of a brilliant scientist, an outstanding scythologist S. A. Skoryy. I suppose this essay, devoted to the Early Scythian period in the south of West Siberian Plain, will be interesting for our hero of the day. The atricle present the reconstruction of migration flows during the Late Bronze to Iron Age transition in the south of West Siberian plane based on archaeological data from Chicha 1 and Bolshoy Log settlements. The main vectors of migration flows, revealed and described in this article, indicate a strong penetration of different archaeological cultures to the Ob-Irtysh forest steppe. The bearers of Suzgun, Atlym, Berlik and other cultures that occupied nearby territories for more than two centuries have adapted to aboriginal late Irmen population. The Ob-Irtysh area was an attractive place for living. The abundant pastures with a stable herbage yields and the wealth of fish and game equally attracted both herdsmen and fishermen-hunters. Apparently, during this time the migration flows changed their directions and didn’t get in each other’s way. The mosaic of cultural formations peacefully shared Ob-Irtysh area was developed in the south of West Siberian plane during Bronze to Iron Age transition. This has been possible because of the different orientation of paleoeconomy of these societies. Besides, it must be noted that the bearers of aboriginal late Irmen culture were quite tolerant. They involved newcomers in their influence arena and even lived with them on the one living space area, e. g. on settlements. This evidence of this behavior was discovered on Chicha 1 and Bolshoy Log sites for instance.

BRONZE CROSS-SHAPED PLAQUES AS A CHRONOLOGY INDICATOR OF SKYTHIAN KURGANS OF THE NORTH PONTIC REGION OF THE SECOND — THIRD QUARTER OF THE 4th CENTURY BC
Authors: Polin S. V. , Daragan М. N.
Published: February 2020

In the Scythian kurgans of the IVth century BC in the Northern Black Sea region, 31 bronze cruciform plaques were found. Such plaques are found mainly in male graves and much less often in female ones. These plaques were used as quiver buckles and for attaching the quiver to the belt. The main zone of concentration of cross-shaped plaques finds covers is the territory of the Lower Dnieper region, directly to the Dnieper. Apparently, this indicates that they were made in this region, where their place of manufacture could be only Kamenskoe hillfort, which was the center of metallurgy and metalworking in Steppe Scythia. From here they diverged south-east to Sivash within the present-day Kherson region, and much further north to the forest-steppe within the present-day right-bank Cherkasy and left-bank Kiev regions. Cross-shaped plaques are indicators of the advance of the steppe Scythians from the Lower Dnieper region to the north in the Ukrainian forest-steppe, to the west as far as the Lower Danube and very close to the south-east to Sivash. The latter direction, apparently, corresponds to migrations to winter pastures. More than half of all finds of cross-shaped plaques reliably date from within the second to third quarters of the IVth century BC, which gives every reason to assume the same dating for the complexes, where there are no own dating materials. In general, such bronze cross-shaped plaques are a reliable chronological indicator Scythian burials of the Northern Black Sea region of the second — third quarter of the IVth century BC, and also partly ethnic.
CLAY BOWLS OF THE SHYRIAIEVO HILLFORT
Authors: Karavaiko D. V.
Published: February 2020

In the Scythian period, one of the regional features of the monuments in the Seim region was a small number of such tableware as bowls. The materials of the Shyriaievo hillfort in the Middle river Seim valley allow us to look at this issue from another position. So, if for the rest of the Left Bank forest-steppe there is a tendency to decrease the percentage ratio of the bowls from early to late Scythian periods, for the territory of the Seim region — the situation is directly opposite. However, the layer of the 4th century BC with the materials of the forest-steppe shapes there is only on the one hillfort — Shyriaievo, which does not allow extrapolating the conclusions to the whole region. It is not excluded that the population that left the upper horizon of the monument is alien. The question of migration from the south of the Sula River Group population to the Seim region, according to the materials of the hillfort Shyriaievo, remains open.
THE HABITATION LAYER OF THE LATE HALLSTATT PERIOD AT THE TRINCA «IZVORUL LUI LUCA» SITE (Northern Moldavian Plateau Area)
Authors: Leviţki O. , Sîrbu L. , Sîrbu G.
Published: February 2020

The Trinca «Izvorul lui Luca» site is an archaeological object with several cultural and chronological horizons, including the late Hallstatt period. The settlement of this period is attributed to the Western Podolian / Podolian-Moldavian cultural group and is the only one investigated in the Northern Moldavian Plateau. The investigations have revealed a number of complexes (dwellings, auxiliary structures, platforms, hearths, and pits), artifacts made of various raw materials (clay, sand, stone, bone, and metal — bronze and iron), a considerable amount of other archaeological remains (pottery, osteological material, stones, fragments of fired clay, etc.) The detailed and overall analysis of all elements specific to the material culture gives us novel information about the way of living, the architectonics of the dwellings, and so on. All this plays a very important role in the research of the cultural and historical processes of the late Hallstatt period in the East Carpathian region in general and in the Northern Moldavian Plateau in particular. The results undoubtedly confirm once again that this region was a zone of cultural interference between the late Hallstatt communities (Thracian) in the Carpathian-Dniester area and the communities in the forest—steppe on the right bank of the Dnieper that existed simultaneously with them.

The article is sanctified to description of standards of weapon twenty-four hours of early ferrous age, that is kept in the display of historical museum of Kamyanka of state Historical and Cultural Center reserve of the Cherkasy areal.

In this paper, brief information is provided on similar analogues of weapons that were found on the territory of Ukraine. But their short description is made. Particularly worthy to highlight the Scythian sword-akinak, which is made in uncharacteristic for this type of form, with a slightly curved blade and one-sided sharpening. This type of weapon is a unique achievement of weaponry and dates from the second to the third quarter of the Vth century BC. Also at the end of the work there is a conclusion regarding the existence of certain types of weapons in the Prytyasminsky region.
SCYTHIAN SWORD FROM SLOVIANSK
Authors: Shelekhan O. V. , Kyrkach V. A.
Published: February 2020

Recently new chance find of the Scythian long sword was presented in the Sloviansk regional museum. Thanks to attention of activists and officials, it was restored in a proper manner.

The sword has zoomorphic antenna pommel, triangular crossguard and long blade with grooves. Due to analogies from the burials, this sword dates by the middle — late 5th century BC. Similar finds are known from Beresniahy, barrow 4, Aktash, barrow 48 and others.

This period was time of permanent conflicts and instability in Northern Black Sea region. For example, such prominent sites as Motronyn and Western Bilsk hillforts became desolate. It is interesting that range of 5th century BC bladed weapon was very wide.

At the same time, Sloviansk region was sparsely populated frontier of the Scythian culture. However, there are known some individual weapon chance finds and separated burials. They are located near the watershed rout that later was named Muravskii way. We can assume that they mark area of nomad’s strategic interests and points of clashes for the salt lakes and fertile floodplains in the Siverskii Dinets basin. In addition, it should be noted that hypothesis about chance finds of swords as remains of Ares’s altar has no reliable evidences.
THE ELITE GRAVE OF THE WARRIOR OF THE PRE-SCYTHIAN AGE NEAR MAIKOP
Authors: Erlikh V. R.
Published: February 2020

The Ulka I cemetery was discovered on the site of the ancient Ulka settlement during rescue excavations conducted by A. V. Surkov in 2017. It is located 5.4 km northeast of Maykop (Adygea, RF). A total of four Proto-Maeotian burials were uncovered in these burial grounds. This article focuses on the wealthiest burial 3, which contained the remains of a warrior flanked by two horse skulls to the south — apparently in imitation of a cart or chariot. The burial inventory consisted of a long bimetallic sword with a length of 108 cm, a spearhead, a quiver with nine bronze arrows, gold and silver pendants of the «Šarengrad» type, gold-plated bronze buttons and various other items. Ananalysis of the funeral inventory shows that the main items belong to the Chernogorovka or Pre-Novocherkassk category of Proto-Maeotian material. However, the burial also contains later chronological indicators, e. g. arrowheads of the «Novocherkassk type» and aclasp of the «Slobodzeya» type. In general, it is possible to suggest a dating within the second half of the 8th century BC for the complex. The burial inventory indicates that the deceased belonged to the highest military elite of Proto-Maeotian society. He probably took part in military campaigns in the Trans-Caucasus, owned multiple herds of horses, and oversawtransactions and exchange with the elite of Central Europe.
GRIFFIN AND SNAKE IN SCYTHIAN ART
Authors: Alekseev A. Yu.
Published: February 2020

The note suggests the interpretation of a group of bronze pole-tops with a depiction of a griffin originated from Krasnokut Grave and some other burial mounds as representing the gnawing of a snake. The subject is extremely rare in the Hellenistic-Scythian art, close to him is known only one item — a gold plate of the sheath from the Elizavetovsky burial ground on the Lower Don-river. The reasons for the appearance and the essence of this composition remain unclear, except the most general assumption about the existence of ideas about the opposition of fantastic creatures — some kind of mediators associated with several zones of the Scythian Cosmos (mainly the upper ones), from the one side, to the animals (snakes) of the lower, chthonic and hostile to man zones, from the other.
IMAGES IN SCYTHIAN ANIMAL STYLE ON THE ARTEFACTS OF «CRIMEAN COLLECTION»
Authors: Kantorovich A. R.
Published: February 2020

Article presents the results of the integration of the array of zoomorphic images on the objects from the «chance finds» collection stored in the Archaeological Museum of the Institute of Archaeology of NAS of Ukraine and published by S. A. Skoriy and R. V. Zimoviec, in the systematics of the images of the Eastern-European Scythian animal style created by the author, based on the latest data. The realized iconographic and statistical analysis suggests, on the one hand, the authenticity of most of the items of the «Crimean collection» (conditional term proposed by the author), decorated in the manner of the Scythian animal style, on the other hand, that these items can be initially located not only in the Crimea, but also in other regions of the Scythian archaeological culture, and primarily from the regions of the Kuban and the Middle and Lower Dnieper basins.
TWISTED AND FALSE-TWISTED TORQUES FROM THE BOSPORAN TOREUTIC WORKSHOPS
Authors: Babenko L. I.
Published: February 2020

For now five neck or pectoral ornamentals are known that have twisted or falsely twisted binders, which were made in the workshops of the Bospor jewelers. The binders construction is represented by three types which are different in their structure. The torque from the primary burial Kul-Oba is related to the first type. Its binder consisted of the twisted bronze pivot covered by a thin golden sheet, which followed the binder shape. The binders of the ornamentals of the second type represent a hollow pipe, which relief imitated the six round pivots spiral twisting (the torque from Solokha, the pectoral from the Tolstaya Mogila). The ornamentals of the third type have a binder that is made of twisted pipes or wires (the torque from the Kul-Oba, the pectoral from the Bolshaya Blyznitsa).

The first four ornamentals can be the products of the same workshop, and they can be made by the jewelers of two or three generations. The craftsman who made the pectoral from the Bolshaya Blyznitsa was most likely working in another workshop.

On the basis of the burial context, the torques (pectorals) with a massive twisted/falsely twisted binder can be considered as one of the markers of royal dignity of its owner.

Background: The evaluation of leprosy patients requires a careful dermatological and neurological examination in order to monitor the possible damage to the peripheral nerves. This study focused on evaluate the sensitivity at the time of diagnosis and discharge of leprosy patients from Dermatology Department of the State University of the State of Pará.  

Methods and Findings: this is a longitudinal, retrospective and descriptive study based on medical records that presented neurological assessment and degree of physical disability of 30 patients assisted at a referral service between 2016 and 2019, applying descriptive statistical analysis. Concerning neural involvement, 88.89% of the patients with neural damage were male, 100% of patients in this group were multibacillary (p-value: 0.02), 42.8% were borderliners (p-value: 0.04), 88.8% had some type of leprosy reaction (p-value: 0.02) and 44.4% of the patients had a diagnosis of leprosy with more than one year of disease evolution; most patients with neural involvement (N = 16) had more than one nerve affected, with the right tibial nerve being the most affected (24.14%); It was noted that a considerable portion of multibacillary patients did not improve or worsened (75%), and the borderline form was the one with the worst prognosis, showing 50% of patients did not respond to treatment.

Conclusions: Most of the patients with neural damage were multibacillary, and borderliners, with many of those without presenting improvement, or showing worsening of clinical condition after multidrug therapy. Thus, it is highlighted the primary role of longitudinal assessment of those patients, in view of the possibility of chronification and sequel development.

Authors: Jo Kyung Hee , Park Jong , Ryu So Yeon
Published: February 2020

OBJECTIVES: This study aimed to identify the effect of mental health on frequency of falls (single and recurrent falls) among elderly adults.METHODS: Data were drawn from the 2015 Korean Community Health Survey. A chi-square test was conducted to compare differences in fall frequency according to health-related behaviors, chronic diseases, and mental health. Subsequently, multinomial logistic regression analysis was used to identify the effects of mental health on single and recurrent falls based on variables found to be significant in the chi-square test.RESULTS: Recurrent falls were found to be more risky than single falls. Depression was significantly related to single falls (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.12 to 1.44). Depression (OR, 1.56; 95% CI, 1.38 to 1.76), sleep disorder (5 hours or less: OR, 1.12; 95% CI, 1.02 to 1.23; more than 9 hours: OR, 1.24; 95% CI, 1.07 to 1.44, respectively), and subjective stress (OR, 2.30; 95% CI, 1.90 to 2.78) were significantly related to recurrent falls.CONCLUSIONS: The study’s findings suggest that specialized fall prevention programs are needed to address different types of falls in elderly adults. To prevent recurrent falls, systematic treatment strategies and rehabilitation training must improve physical function and mental health.

Published: February 2020

Iako su tendencije brojnih istraživača dugi niz godina bile usmjerene prema kvantitativnim metodama i statističkim procedurama te pojedinim kvalitativnim metodama i izvorima podataka, posljednjih godina brojni autori govore o uočenom povećanju interesa prema pristupu životne povijesti. Svoje značajne začetke životna povijest bilježi upravo u sociologiji. Unatoč tomu, područje sociologije u Hrvatskoj i dalje ne pokazuje znatniji interes za raspravom teorijskih i metodoloških aspekata životne povijesti. Ovisno o interesima istraživača, životna povijest može se promatrati kroz različite perspektive, kao teorijsko-metodološki okvir, ali i kao metoda istraživanja. Ona omogućuje načine dubinskog dokumentiranja individualnih priča unutar društvenog konteksta tijekom određenog vremena te je pogodna za istraživanje širokog spektra fenomena što ističe metodološku snagu ovog pristupa. Unatoč tomu, kao i kod drugih kvalitativnih pristupa, i kod životne povijesti pojavljuju se pitanja vezana uz refleksivna razmatranja istraživačkog dizajna, te ostala specifična metodološka i etička pitanja. S druge strane, njezine metodološke i istraživačke prednosti u istraživanjima brojnih društvenih fenomena upućuju na potrebu razmatranja uloge pristupa životne povijesti u suvremenoj sociološkoj metodologiji.

Sosyal medyanın yaygınlaşması ile birlikte bilgiye her yerden ve herkes tarafından ulaşılmaya başlanmış; bilginin kolayca dolaşıma girmesi ve yaygınlaşmasıyla birlikte sosyal medya öncesi dönemde var olan pek çok tabu da yıkılmaya başlamıştır. Daha önce ulaşılmaz ve sadece belli sosyo-ekonomik sınıflara ait olduğu düşünülen pek çok şeyde sosyal medyanın gücünün keşfiyle birlikte bir tür havastan avama yayılma formunu almıştır. Estetik işlem uygulama ve uygulatma da yine sosyal medyanın yaygınlaşmasıyla birlikte form değiştirerek belli sosyo-ekonomik sınıfların yaptırdığı bir tedavi olmaktan çıkıp sıradan bir insanın da öğle yemeği arasında gidip yaptırdığı bir işleme dönüşmüş, bir ihtiyaç halini almıştır.
Kullanıcılar sosyal medyada plastik cerrahların, estetisyenlerin tanıtımları vasıtasıyla bu işlemlerin ve estetik işlem uygulayıcıların ulaşılabilir olduğunu fark etmiş, bu işlemi yaptıran kendi gibi insanları gördükçe de bu işlemlerin bir ihtiyaç olduğuna hükmetmiştir. Bu bağlamda sosyal medyanın toplumdaki estetik işlem yaptırtma algısı üzerindeki etkisini ölçmek üzere sosyal medya hesaplarında çeşitli estetik sayfalarını takip eden, farklı demografik sınıflardan 116 kişiyle online anket çalışması yapılmıştır.

Anlamın ne olduğu farklı disiplinlerde çalışan araştırmacıların cevabını aradığı en önemli sorulardan biri olmuştur. Anlamın ne olduğu ve nasıl inşa edilebileceği sorusunu soran Ferdinand de Saussure, Roland Barthes, Julia Kristeva, Jacques Derrida ve Friederich Nietzsche gibi Batılı kimi dilbilimciler ve felsefeciler göstergeden başlayarak varlık, metin ve okuyucuya kadar uzanan konularda önemli tartışmalar yapmışlardır. Neticede bu uzun serüven nihilizme kadar uzanmıştır. İşte bir makalenin sınırlı kapsamında, bu serüven bazı boyutlarıyla ortaya konulmakta; dili oluşturan göstergelerin nasıl çağrışım gücünü yitirdiği, metnin öz bir metin olmaktan çıktığı, yazarın devre dışı kaldığı gibi hususlar üzerinde durulmaktadır. Göstergenin kendinden başka bir şeye işaret edememesi varlık anlamında da önemli sorunlara yol açmıştır. Çünkü kendisinden başka bir şeyi gösteremeyen göstergelerle inşa edilen ve başka metinlerle metinlerarası ilişkiye sahip olan bir metin ne müellifine, ne de yaratıcı gücüne göndermede bulunabilir. Derrida da her bir gösterileninin aynı zamanda başka bir şeyin göstergesi olabileceğine, kökenin yokluğundan dolayı her şeyin söyleme dönüşebileceğine ve anlam alanının sonsuz genişleyebileceğine vurgu yaparak, kâinatta ilanihaye göstergeler arası bir dönüşün ve devinimin süregittiğine, dilin doğası üzerinden varlığın kendikendiliğine ve sonsuzluğuna işaret etmiştir. Bu ebedi yeniden doğuş ya da ayni olanın yeniden doğması, “kendikendinelik”, varoluşun gayesini, ‘yaratıcı’ ile şeyler arasındaki ilişkiyi, boşa çıkarmakta ve hiçlik düşüncesini daha da pekiştirmektedir. Üzerinde durulması gereken diğer bir husus ise kendine özgü bir dili olan ve bu dilsel mantık üzerinden işleyen televizyonun nihilizm ile olan ilişkisidir. Bu anlamda cevabının aranması gereken en önemli soru televizyon ve nihilizme nasıl yol açtığıdır.

Background and Purpose Although onset-to-treatment time is associated with early clinical recovery in acute ischemic stroke (AIS) patients treated with intravenous tissue plasminogen activator (tPA), the effect of the timing of tPA-induced recanalization on functional outcomes remains debatable.Methods We conducted a multicenter, prospective observational cohort study to determine whether early (within 1-hour from tPA-bolus) complete or partial recanalization assessed during 2-hour real-time transcranial Doppler monitoring is associated with improved outcomes in patients with proximal occlusions. Outcome events included dramatic clinical recovery (DCR) within 2 and 24-hours from tPA-bolus, 3-month mortality, favorable functional outcome (FFO) and functional independence (FI) defined as modified Rankin Scale (mRS) scores of 0–1 and 0–2 respectively.Results We enrolled 480 AIS patients (mean age 66±15 years, 60% men, baseline National Institutes of Health Stroke Scale score 15). Patients with early recanalization (53%) had significantly (P<0.001) higher rates of DCR at 2-hour (54% vs. 10%) and 24-hour (63% vs. 22%), 3-month FFO (67% vs. 28%) and FI (81% vs. 39%). Three-month mortality rates (6% vs. 17%) and distribution of 3-month mRS scores were significantly lower in the early recanalization group. After adjusting for potential confounders, early recanalization was independently associated with higher odds of 3-month FFO (odds ratio [OR], 6.19; 95% confidence interval [CI], 3.88 to 9.88) and lower likelihood of 3-month mortality (OR, 0.34; 95% CI, 0.17 to 0.67). Onset to treatment time correlated to the elapsed time between tPA-bolus and recanalization (unstandardized linear regression coefficient, 0.13; 95% CI, 0.06 to 0.19).Conclusions Earlier tPA treatment after stroke onset is associated with faster tPA-induced recanalization. Earlier onset-to-recanalization time results in improved functional recovery and survival in AIS patients with proximal intracranial occlusions.

Background and Purpose Previous studies suggested increased visit-to-visit variability of total cholesterol (TC) is associated with stroke. This study aimed to investigate the associations of various lipids measurements variability and the risk of stroke and stroke type (ischemic and hemorrhagic stroke).Methods Fifty-one thousand six hundred twenty participants in the Kailuan Study without history of myocardial infarction, stroke, and cancer who underwent three health examinations during 2006 to 2010 were followed for incident stroke. Variability in TC, triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) measurements were measured using the coefficient of variation (CV), standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV).Results During a median of 6.04 years of follow-up, 1,189 incident stroke (1,036 ischemic and 160 hemorrhagic stroke) occurred. In the multivariable-adjusted model, the hazard ratio (HR) comparing participants in the highest versus lowest quartile of CV of HDL-C were 1.21 (95% confidence interval [CI], 1.02 to 1.45; P for trend=0.013) for ischemic stroke. The highest quartile of CV of LDL-C was associated with 2.17-fold risk of hemorrhagic stroke (HR, 2.17; 95% CI, 1.25 to 3.75; P for trend=0.002) compared with the lowest quartile. We did not observe any significant association between TC and triglycerides variability with any of stroke. Consistent results were obtained when calculating variability index using SD, VIM, or ARV.Conclusions These findings suggest the high visit-to-visit HDL-C and LDL-C variability were associated with an increased incidence of ischemic and hemorrhagic stroke, respectively.

O fogo possui seus primeiros registros há cerca de 1,5 milhões de anos, e acompanha as sociedades humanas em seus processos históricos, seja por meio das práticas intencionais, ou em situações de perda de controle e consequentes danos. A complexidade dos fenômenos das queimadas e dos incêndios florestais tendem a ser de caráter interdisciplinar, e geram a possibilidade de aprofundamento epistemológico quanto aos estudos sobre o fogo. Vale destacar que as queimadas são aplicadas para manutenção de áreas agrícolas e de pastagem, e por vezes as ações antrópicas do atear as queimadas conflagram incêndios florestais. A metodologia é de caráter quali-quantitativo com uso da pesquisa bibliográfica e análise documental para subsídio do caráter qualitativo, e levantamentos em gráfico e quadros numéricos para o caráter quantitativo, bem como o caráter explicativo quanto ao objetivo e à justificativa da pesquisa.  O Brasil apresenta registros de focos de calor em todas as regiões do país, e o Estado do Tocantins se destaca pela proporcionalidade dos incêndios de Classe V, e por compor entre os primeiros colocados o ranking nacional de registros de queima no período de 2009 a 2018, mesmo possuindo a nona área territorial dentre os dez primeiros. Por delimitação territorial e uso do sensoriamento remoto foi possível conhecer o município tocantinense de maior registro histórico dos focos de calor ativos. Ao final do estudo se conclui que o resultado foi de caráter total, uma vez que o objetivo deste estudo foi alcançado em sua totalidade.

This study aims to analyze and compare the transportation feasibility of the following three tsunami evacuation support devices that carry vulnerable persons: (A) a rollator, (B) a transport chair, and (C) a wheelchair. Each of these supports was examined for its feasibility during transit along a steep slope, gentle slope, and flat land. The results indicated that the rollator was the most feasible tool, followed by the transport chair and the wheelchair; however, having the assistance of support personnel enabled the victims to flee faster and more effectively. Furthermore, the findings indicate that although wheelchairs are the most effective in evacuating vulnerable persons, all the studied tools can provide assistance.

Double‐crop soybeans [Glycine max (L.) Merr.] have the potential to be a productive and profitable system. However, due to delayed planting, double‐crop soybeans frequently experience lower yields and higher stress. Because planting is a major production constraint, a critical practice is the management of previous wheat residue. Trials were established in 2012, 2013, and 2014 in Saint Joseph, LA, and in 2013 and 2014 in Winnsboro, LA. The four residue management treatments investigated included conventionally tilled, planted into burned residue, planted into mowed residue, and planted into standing wheat residue. Vegetative and reproductive growth parameters, as well as yield, were used to evaluate the influence of residue management on productivity. Overall, residue management did not have a significant impact on early season growth parameters, except for plant height in 2012 at St. Joseph; however, it did significantly influence yield at both locations. In Saint Joseph in 2012, yields from planting into wheat residue were significantly lower than burned and mowed plots (1.2 compared with 2.8 and 2.7 Mg ha−1, respectively), and tilled treatments yielded significantly less than all three nontilled treatments in 2013 and 2014. In Winnsboro, planting into residue left on the soil surface resulted in significantly higher yields than when residue was removed. Overall, leaving residue on the soil surface provided stable yields across years and locations; however, not managing the residue can result in diminished yields. Therefore, practices such as mowing of wheat residue prior to planting provide an alternative to traditional no‐till planting.

Despite the extensive potential of zeolitic imidazolate framework (ZIF) membranes in gas separation, the development of continuous, oriented ZIF membranes onto a polymeric substrate remains a significant challenge. This is presumably due to weak adhesion, and insufficient heterogeneous nucleation sites on the polymer surface. Herein, a layer of horizontally aligned poly(sodium‐4‐styrene sulfonate)‐modified halloysite nanotubes (PSS‐HNTs) with ample nucleation sites was used for templated growth of vertically oriented Zn‐ZIF‐L layers. Then we successfully developed the first well‐intergrown membranes of Co‐ZIF‐L on Zn‐ZIF‐L layers via heteroepitaxial growth. The stepwise deposition was utilized for the control of ZIF films orientation to avoid random nucleation and twins overgrowth. The integration of preferred vertical orientation and optimized grain boundary structure endowed the Co/Zn‐ZIF‐L membranes with a remarkable gas separation performance (CO2 permeance: 244.9 GPU, and CO2/N2 selectivity: 17.8). Our methodology provides a useful guideline to design mixed‐component, vertically oriented ZIF‐L to improve gas separation performance.
