Norovirus is the most common cause of epidemic and endemic acute gastroenteritis. However, national estimates of the infection burden are challenging. This study used a nationally representative serum bank to estimate the seroprevalence to five norovirus genotypes including three GII variants: GI.1 Norwalk, GI.4, GII.3, GII.4 US95/96, GII.4 Farmington Hills, GII.4 New Orleans, and GIV.1 in the USA population (aged 16 to 49 years). Changes in seroprevalence to the three norovirus GII.4 variants between 1999 and 2000, as well as 2003 and 2004, were measured to examine the role of population immunity in the emergence of pandemic GII.4 noroviruses. The overall population-adjusted seroprevalence to any norovirus was 90.0% (1999 to 2000) and 95.9% (2003 to 2004). Seroprevalence was highest to GI.1 Norwalk, GII.3, and the three GII.4 noroviruses. Seroprevalence to GII.4 Farmington Hills increased significantly between the 1999 and 2000, as well as the 2003 and 2004, study cycles, consistent with the emergence of this pandemic strain. Seroprevalence to GII.4 New Orleans also increased over time, but to a lesser degree. Antibodies against the GIV.1 norovirus were consistently detected (population-adjusted seroprevalence 19.1% to 25.9%), with rates increasing with age. This study confirms the high burden of norovirus infection in US adults, with most adults having multiple norovirus infections over their lifetime.
DEAD-Box Helicases: Sensors, Regulators, and Effectors for Antiviral Defense
Authors: Taschuk Frances , Cherry Sara
Published: February 2020

DEAD-box helicases are a large family of conserved RNA-binding proteins that belong to the broader group of cellular DExD/H helicases. Members of the DEAD-box helicase family have roles throughout cellular RNA metabolism from biogenesis to decay. Moreover, there is emerging evidence that cellular RNA helicases, including DEAD-box helicases, play roles in the recognition of foreign nucleic acids and the modulation of viral infection. As intracellular parasites, viruses must evade detection by innate immune sensing mechanisms and degradation by cellular machinery while also manipulating host cell processes to facilitate replication. The ability of DEAD-box helicases to recognize RNA in a sequence-independent manner, as well as the breadth of cellular functions carried out by members of this family, lead them to influence innate recognition and viral infections in multiple ways. Indeed, DEAD-box helicases have been shown to contribute to intracellular immune sensing, act as antiviral effectors, and even to be coopted by viruses to promote their replication. However, our understanding of the mechanisms underlying these interactions, as well as the cellular roles of DEAD-box helicases themselves, is limited in many cases. We will discuss the diverse roles that members of the DEAD-box helicase family play during viral infections.
The first case of Bovicola (Werneckiella) ocellatus (Piaget, 1880) (Phthiraptera: Ischnocera: Trichodectidae) on a donkey (Equus asinus Linnaeus, 1758) in Turkey

Published: February 2020

In the clinical examination of a donkey, which brought to the Ownerless Animal Care and Rehabilitation Center of the Hatay Metropolitan Municipality due to neglecting and senility, local hair losses, ruffling and opacity were observed. A few louse specimens were detected on the hair shafts on the back of the donkey during the macroscopic examination. They were collected with a forceps, and preserved in a tube with alcohol 70%. Then they examined in detail in microscope, and identified as Bovicola ocellatus (Piaget, 1880). The presence of B. ocellatus on donkey has been reported for the first time in Turkey in this paper.

Fibulele turnate romano-bizantine / Fibulas with bent stem
Authors: Măgureanu Andrei
Published: February 2020

Cast fibulas with bent stem are one of the most characteristic finds from the second half of the VIth century on Lower Danube. They have a precise area of spreading and a well establish chronology. In this paper I try to propose a new approach regarding typology by renouncing to old criteria. So I suggest the stylistic criteria as the only one to form groups of fibulas. Some of the groups are specific for a small area and some have a larger spreading. Of course, this aspect, the spreading, will always depend of the publication of museum collections from the South of Danube. Also, I try to draw a more accurate image regarding how this type of fibula was produce. The solitary picture of the workshop from Drobeta is now more complete because of some other discoveries, especially those from Caričin Grad. Drobeta still remains the only workshop for mass production. Concerning the chronology, I think I succeed to argue a particular aspect. Most of the fibulas cease to exist after the end of the VIth century. But this is true only for the south Danube finds, because in the Avars area, this type of fibula is still in use till mid VIIth century. A long discussion has been taking related to the dimension of fibulas. I think that beside the economic or mercantilist explications, it can be suggested one based on the dressing rule : the big fibulas was wearied on shoulder level, while the small one was wearied on the basin level. As well, are some indications that fibulas were use, sometime, in pare or attach by a small chain by other dressing elements. It is hard to indicate, according to present data, if this type of fibula belonging to the male or female costume. Finds from the graves suggest the appurtenance to female costume, while the pieces from military fortress hint the male costume. Till new data this is an open discussion. Not to forget the possibility that it can be a unisex type of fibula or the differences of appurtenance can suggest different areas. I have in mind possible differences between the Avar zone and the South of Danube area (Byzantine Empire). Anyway, these fibulas are not an ethnic symbol. It represents a Byzantine product that, in small number, was exported in Barbaricum. It is the mark of a dressing mode developed in a short time and in a well delimited area.
Stable Isotope Evidence for Early Modern Human Diet in Southeastern Europe: Peştera cu Oase, Peştera Muierii and Peştera Cioclovina Uscată
Authors: Trinkaus Erik , Soficaru Andrei , Doboş Adrian , Constantin Silviu , Zilhão João , Richards Michael
Published: February 2020

During the process of direct radiocarbon dating of four Early Upper Paleolithic modern humans from the Romanian sites of Peştera cu Oase, Peştera Muierii and Peştera Cioclovina Uscată, carbon and nitrogen stable isotope ratios (δ13C and δ15N) were measured from their bone collagen. These individuals have δ13C values similar to other Late Pleistocene humans. Their δ15N values are well within the carnivore trophic level range, among the higher of the Middle Upper Paleolithic values, and significantly greater than those of preceding Middle Paleolithic and Initial Upper Paleolithic Neanderthals. These data suggest a shift towards a broader faunal dietary spectrum among these early modern humans, despite western and eastern European archeological evidence and human functional morphology indicating little change in faunal exploitation from the Middle Paleolithic to the Early Upper Paleolithic.
Nouvelles recherches sur le gisement paléolithique de Mitoc Valea Izvorului (dép. de Botoşani) Fouilles 2003–2004
Authors: Tuffreau Alain , Chirica Vasile , Balescu Sanda , Haesaerts Paul
Published: February 2020

Previous studies of the Mitoc-Valea Izvorului site (Prut Valley, Romania) have suggested the presence of a transitional industry between Middle and Upper Palaeolithic. During recent excavations (2003-2004), new chronostratigraphical investigations together with OSL sediment dating have demonstrated the presence of Middle Palaeolithic artefacts and Upper Palaeolithic artefacts within distinct stratigraphical units. Stratigraphical correlations have been made with the nearby Malu Galben site including Aurignacian and Gravettian.
Consideraţii arheologice / The rupestrian site of Murfatlar- Basarabi, 50 years after its discovery archaeological investigations
Authors: Damian Oana , Samson Andra , Vasile Mihai
Published: February 2020

Autorii fac o trecere în revistă a rezultatelor cercetărilor arheologice desfăşurate în situl de la Murfatlar-Basarabi, dublată de prezentarea planului general al ansamblului şi de valorificarea unor situaţii şi materiale arheologice rămase inedite. Situl arheologic Murfatlar-Basarabi se află pe malul drept a ceea ce a fost Valea Carasu, acum Canalul Dunăre-Marea Neagră, la 20 km vest de Constanţa, pe versantul nord-vestic al dealului Tibişir. A fost descoperit la 11 iunie 1957, în urma unor lucrări de extindere a zonelor de exploatare a cretei în cariera modernă, lucrări care au dezvăluit deschiderea uşor arcuită a unei bisericuţe ce va fi numită B1. Cercetările arheologice desfăşurate în perioada 1957-1962, prin eforturile reunite ale Institutului de Arheologie din Bucureşti (astăzi Institutul de Arheologie „ Vasile Pârvan”), reprezentat de Ion Barnea, în calitate de responsabil de şantier, şi ale Direcţiei (astăzi Institutul Naţional al) Monumentelor Istorice, prin intermediul arhitecţilor Virgil şi Liana Bilciurescu, au dus la identificarea unui ansamblu de monumente conţinând exploatări de carieră, bisericuţe şi chilii, locuinţe şi morminte. În 1960, din cauza vizibilului proces de erodare a cretei, au demarat acţiuni de conservare, materializate în consolidarea şi restaurarea monumentului prin anastiloză la adăpostul unei construcţii de protecţie parţiale. Prin caracteristicile arhitectonice, prin varietatea abundentei decoraţii incizate, prin prezenţa a numeroase inscripţii, ale căror conţinut şi interpretare continuă să suscite controverse, monumentul s-a constituit într-un exemplu aparte de descoperire, cu probleme particulare de investigare, înregistrare, interpretare, conservare şi punere în valoare.

Un mormânt sarmatic descoperit la Călăraşi / A Sarmatian grave found in Călăraşi
Authors: Oţa Liana , Comşa Alexandra
Published: February 2020

Publicat în 1952 ca analogie pentru un mormânt din Moldova, complexul funerar de la Călăraşi nu a beneficiat de o discuţie sau de o prezentare detaliată a inventarului şi nici de ilustraţie. Conform datelor publicate iniţial, este vorba de un mormânt de inhumaţie, al unei persoane de sex feminin, descoperit întâmplător în 1948 (în punctul Aeroport). Pe lângă craniul deformat, s-au recuperat „ două căni, câteva perle octogonate şi o oglindă”. Din păcate, nu am putut regăsi decât craniul, conservat parţial, şi cele două vase (cană şi urcior, ambele din pastă cenuşie, cu decor lustruit). Analogiile pentru cele două recipiente ceramice şi prezenţa în inventarul mormântului a mărgelelor poliedrice sugerează o datare a complexului aflat în discuţie în cursul secolului al III-lea p. Chr., fără a putea, cel puţin în actualul stadiu al cercetării, restrânge această datare. Conform analizei antropologice, craniul aparţine unui individ de sex feminin, mai degrabă de vârstă matură.
Boineşti (département de Satu-Mare), Moustérien, Aurignacien et processus taphonomiques
Authors: Tuffreau Alain , Dobrescu Roxana , Balescu Sanda , Văleanu Mădălin-Cornel
Published: February 2020

During the new excavations at Boineşti (2005– 2006), Middle Palaeolithic and Aurignacian artefacts have been discovered within the loessic deposits. Three archaeological units (D, C1, C) have been identified. The raw material is varied. IRSL dating of these loessic deposits indicates that the Mousterian material (unit D) belongs to MIS 3 and that the Aurignacian material (units C1 and C) has been reworked during the Holocene. During this reworking episode, the Mousterian artefacts from the lower loessic deposit have been incorporated within the Aurignacian units (C and C1). Refittings of the pieces coming from different archaeological units confirm this interpretation.
New Evidence on Burial Practices in Petreşti Culture

Published: February 2020

The aim of the current paper is to present two inhumation graves belonging to Petreşti culture recently discovered within the Petreşti-Groapa Galbenă settlement (Alba County, Transylvania). The burial of a deceased in a cist made of adobe pieces represents an unusual funerary practice for the Eneolithic Petreşti culture communities. This discovery is especially important because the current state of research related to the mortuary practices of Petreşti culture bearers is not satisfactory.
Fibule „de tip hibrid”? / "Hybride Fibeln" ?
Authors: Spânu Daniel
Published: February 2020

În 1969, într-un mormânt de incineraţie a fost descoprită la Zimnicea o fibulă cu două resorturi bilaterale, ambele funcţionale (fig. 1). Această construcţie atipică a prilejuit presupunerea existenţei unor ipotetice serii tipologice de fibule caracterizate ca „ încrucişări traco-celtice” (thrakischkeltische Kreuzungen/ types hybrides thraco-celtiques). Ele ar combina în egală măsură elemente ale fibulelor de schemă La Tène şi ale fibulelor cu resort lateral şi picior ridicat (fibule „tracice”). Cu timpul, sub eticheta „fibule hibride” sau „de tip hibrid” au fost reunite pur şi simplu fibule de schemă La Tène sau fibule tracice lipsite de orice „ hibridizare”. Doar unele motive ornamentale specifice anumitor tipuri de fibule de schemă timpurie La Tène au fost integrate în mod izolat pe structura tradiţională (în spaţiul extracarpatic) a unor fibule „tracice” (fig. 2-centru, fig. 3/ 23 şi 26). Aceste împrumuturi au condus la diversificarea repertoriului ornamental al fibulelor cu resort lateral şi picior ridicat (aşa numitele fibule „tracice”), dar nu au determinat apariţia unor serii tipologice distincte. Din acest motiv, noţiunea de „tip hibrid” pentru astfel de fibule nu se vădeşte nici consecventă, nici justificată.
Cercetări arheologice în Curtea Domnească de la Târgşoru Vechi / Archaeological research in Voivodal Court at Târgşoru Vechi
Authors: Ciupercă Bogdan , Măgureanu Andrei , Paveleţ Eugen , Sârbu Dorin
Published: February 2020

Over 50 years ago, an archaeological team initiated the research in the area of the medieval town from Târgşoru Vechi. In 1956 only the ruins of three churches and some fragments of the buildings of the former Voivodal Court and Turnu monastery could still be observed. Those medieval remains were the starting point for the investigation of Târgşoru Vechi town, a town that today celebrates 600 years since it was first mentioned in a medieval document. The Novo Foro, as it was known in the Latin version of the document issued by Mircea cel Bătrân to the merchants of Braşov, was an important custom point, voivodal residence and later on, monastery. Following a project of restoration proposed by the architect C. Hoinărescu, archaeological excavations in the area of the Medieval Court were resumed in 2005. Excavations during two seasons (2005, 2006) aimed to verify and complete the results of the previous research undertook by N. Constantinescu, research that was abruptly stopped in the mid-1960-ies. The recent investigations provided new data about structures from interior of the Voivodal Court area, identifying a first habitation level going back to the 15th century. Also, the existing information referring to the cellar of the Voivodal House was completed with new data and a new chronological interpretation of other structures was proposed. A new opened surface (located in the north-east corner of the second medieval enclosure) allowed the identification a long-term inhabitated area, with the same evolution from the mud-bricks constructions to stone ones.

Published: February 2020

Articolul prezintă patru contexte ceramice de epocă romană timpurie provenind din sondajele efectuate în sectorul central al cetăţii romane târzii pentru identificarea Bazilicii C, anterioare bazilicii episcopale din sec. VI. Acestea surprind cel puţin două momente cronologice : contextul 1 datează de la sfârşitul sec. I a. Chr. şi prima jumătate a sec. I p. Chr. ; acest prim context oferă un bun terminus post quem pentru contextele 2– 4, care aparţin unor structuri de locuire databile în a doua jumătate a sec. I şi în prima jumătate a sec. II p. Chr. Loturile ceramice analizate pot contribui pe viitor la nuanţarea cronologiei primelor secole ale epocii romane de la Histria (fazele I A şi I B).

Dintre piesele de metal ale epocii bronzului de la Dunărea de Jos se remarcă unele lame de cupru sau bronz, de dimensiuni considerabile, cu nervură mediană pronunţată. Cele mai multe dintre ele au fost descoperite ȋn Muntenia, ȋn zona unor aşezări sau ȋn morminte. Ca aspect şi dimensiuni, sunt foarte asemănătoare cu halebardele din Europa centrală şi de vest. Au fost ele utilizate ca halebarde sau funcționalitatea lor era una diferită la Dunărea de Jos ? În studiul de faţă ne- am propus să examinăm contextele în care apar aceste lame şi piesele cu care se asociază, formele similare identificate în alte spaţii culturale, datarea şi posibila lor funcţie.
Late Roman pottery discovered at Histria in the Acropolis Centre‐South Sector (2015). Vasa escaria – Late Roman C Wares
Authors: Bădescu Alexandru , Iliescu Iulia
Published: February 2020

The 90 pottery fragments presented in this paper were discovered in 2015 at Histria, in the Acropolă Centru‐ Sud sector (excavation coordinated by the University of Bucharest). The pottery pertains to seven forms with 14 types of kitchen ware. This category of artefacts is very important and, at the same time, very discriminated. Common ware – and most of the kitchen ware is part of this category – is overlooked in favour of luxury ware, lamps and amphorae, and a very large quantity of material pertaining to this category remains unstudied. This situation is common, in spite of the fact that, due to its fragility and the lack of a waterproof coating (which means that in a short time organic matter and mold make it unusable), it had a short life and therefore provides archaeologists with a much more refined chronological marker. Apart from the chronological information, the study of kitchenware can shed new light on the trade directions and the zone of political influence in Scythia Minor during the Late Roman period. The publication of the entire pottery lot from and excavation can lead, now or in the future, to the clarification of certain problems for which we can only make suppositions at the present moment.
Descoperiri monetare recente la Histria (Sectorul Acropolă Centru‐Sud) / Recent monetary discoveries at Histria (Acropolis Centre‐South Sector)
Authors: Vîlcu Aurel , Ţârlea Alexandra
Published: February 2020

Within a four-year research project (2013– 2016) funded by the University of Bucharest, a new sector of the archaeological site of Histria (Istria, Constanța County) was opened, conventionally named Acropolis Centre-South (ACS). During the archaeological research from 2013– 2014, 18 trenches (C001– C018) were opened. The numismatic material discovered in 2013 and 2014 inside the Acropolis Centre South sector consists of Greek, Roman and Byzantine coins. Chronologically, the 21 coins discovered inside the Acropolis Centre-South sector and another one found outside are distributed as follows : five Greek coins from 5th– 3rd century BC, a pseudo-autonomous Istrian coin issued most likely in the second half of the 2nd century AD, nine Late Roman Bronze coins from the 3rd– 5th century AD and seven Byzantine coins from the 6th– 7th century AD. We note a rare bronze coin having Apollo seated on the omphalos on obverse and Dionysus accompanied by the inscription ICTPIA-NΩN on revers (no. 13), issued by Istrian mint during Roman period. The chronology of this Istrian bronze coin is still under discussion but some elements suggests a date in the second half of the 2nd century AD, during Commodus’ reign. Two Roman bronze coins, one of CONCORDIA M- LITVM type struck in Cyzicus mint, c. 295– 299 AD, in the name of Diocletian (no. 1) and the second of CONSTANTINIANA DAFNE type issued in the years 328/ 329 in Constantinople mint by Constantin the Great (no. 2) are rare through monetary discoveries from Histria. Habitation in the Acropolis Centre-South sector in the 7th century AD is revealed by a half-follis minted by Phocas, in the years 603– 610 AD. The authors discuss about the last phase of the Byzantine city in the light of the coins discovered at Histria. In 2014, during the excavations from Acropolis Centre-South sector five Greek coins were found : one Macedonian bronze coin struck by Philip II (no. 8) and four Istrian autonomous bronze coins (nos. 9– 12).
The Middle Palaeolithic research in Romania. Past and current issues
Authors: Doboş Adrian
Published: February 2020

This paper presents some new results concerning the Middle Palaeolithic in Romania. Recent research on loess‐ paleosoil sequences and tephra deposits has provided an accurate picture on the geochronology of the Pleistocene. Reliable absolute ages indicate that some Middle Palaeolithic occupations are much older than previously assumed, namely they date back to the Middle Pleistocene. Lithic industries, both coming from old and recent excavations were (re) interpreted from new perspectives, other than cultural-historical ones. The study of fauna still leaves to be desired, as it needs to go beyond mere taxa identification. Many loci that have yielded surface collections of lithics that could belong to the Middle Palaeolithic indicate a great potential for discovering new sites in Romania.
Note on a vessel of unusual type from the Abdera “Teian” necropolis: mini-“Falaieff krater” or thymiaterion?

The Abdera “Teian” necropolis has revealed a Greek vase with unusual morphological features, at first sight recalling those of the so-called “ Falaieff kraters” but which might well alternatively represent a variety of portable thymiaterion, issued from a later 4th / early 3rd century BC tumular context.
Quelques observations d’ordre technologique et typologique sur les industries lithiques découvertes à Atmageaua Tătărască (Sokol, Bulgarie)
Authors: Dobrescu Roxana
Published: February 2020

The site of Atmageaua Tătărască in Southern Dobrudja has a long occupation sequence, spanning from Boian A, Gumelnita A1, Gumelnița A2, to Gumelnița B. With a few exceptions, the archaeological patterns were not recorded during the excavations. The lithic industry includes 976 pieces, for most of them (72.84%) issued from the level III – Gumelnița A1. After analysing the material from level III, several conclusions arise. At least part of the knapping process was carried out locally, viz. for large and medium-sized blades. This paper puts forward the hypothesis of the presence of a workshop involving specialized knappers for level III. Blade production is predominant, and at least two reduction sequences were identified. Two types of percussion are observed : direct percussion with hard hammer (predominant) and indirect percussion ; conversely, pressure flaking technique is lacking. Tools amount to 36.56% of the assemblage and, supplemented by axes, up to 39.09%. Among the tools, the most numerous are burins (33.46%) and endscrapers (27.69%), followed by retouched blades (19.23%) and truncations (9.23%). Less represented tool groups are notches, sidescrapers, scaled pieces, retouched flakes, becs, as well as an arrow point. It is also worth mentioning composite tools (3.65%) and the reuse of old tools, which were re-shaped into new ones. The raw material is of high quality ; it is also fairly homogenous, giving preference to the local Ravno (93.54%) and Kriva Reka type of Ludogorie chert, yellow-brown and grey Upper Cretaceous flint (Moesian flint), but also a dark blue chert possibly issued fromthe middle Prut valley.
Biserica evanghelică din Saschiz, judeţul Mureş. Cercetări arheologice (II): cimitirul exterior / The Evangelical church at Saschiz, Mureş County. Archaeological research (II): the cemetery around the church
Authors: Marcu Istrate Daniela
Published: February 2020

Articolul analizează mormintele descoperite în exteriorul bisericii evanghelice din Saschiz, completând, astfel, datele publicate anterior despre acest monument. Cercetarea arheologică, realizată cu ocazia restaurării, a identificat câteva zeci de morminte, dispuse neregulat în jurul bisericii. Necropola este rarefiată, mormintele sunt repartizate inegal, iar suprapunerile sugerează existența unor locuri de înmormântare familiale. Ritualul de înmormântare este simplu, toți decedații fiind depuși în poziţie culcat pe spate, cu antebrațele așezate în diferite poziții pe bazin sau abdomen. Un aspect interesant este acela că majoritatea mormintelor nu au respectat orientarea tradițională cu capul către vest, fiind influențate de orientarea bisericii, puternic deviată pe axa NV– SE. Niciunul dintre morminte nu a avut obiecte de inventar, drept urmare limitele cronologice ale cimitirului au fost stabilite pe baza datării edificiului religios, a absenței înmormântărilor anterioare acestuia și a studiului stratigrafic. Conform acestor factori, înhumările au început cel mai devreme după mijlocul secolului al XV‐ lea și au încetat după aproape un secol. Caracteristicile topo‐ cronologice ale cimitirului arată că funcția funerară a bisericii a fost de scurtă durată și accesibilă unui număr restrâns de enoriași, cel mai probabil proveniți din familiile reprezentative ale comunității. Astfel, cercetările arheologice de la Saschiz au documentat o situație destul de rar întâlnită în mediul coloniștilor, în care cimitirul parohial a funcționat, în jurul anului 1500, în alt loc decât biserica.

Artificial AlgaeAlgorithm (AAA) is an optimization algorithm that has advantages of swarm algorithm model and evolution model. AAA consists of three phases of helical movement phase, reproduction, and adaptation. Helical movement is a three-dimensional movement with the direction of x, y, and z which is very influential in the rate of convergence and diversity of solutions. Helical motion optimization aims to increase the convergence rate by moving the algae to the best colony in the population. Algae Algorithm Optimization (AAA ') was tested with 25 objective functions of CEC'05 and implemented in case of pressure vessel design optimization. The results of the CEC'05 function test show that there is an increase in convergence rate at AAA ', but at worst condition of AAA' becomes less stable and trapped in local optima. The complexity analysis shows that AAA has the complexity of O (M3N2O) and AAA 'has the complexity of O (M2N2O) with M is the number of colonies, N is the number of algae individuals, and O is the maximum of the evaluation function. The results of the implementation of pressure vessel design optimization show that AAA's execution time increased 1,103 times faster than AAA. The increase in speed is due to the tournament selection process in AAA performed before the helical motion, whereas in AAA 'is done if the solution after movement is no better than before. At its best, AAA 'found a solution 4.5921 times faster than AAA. At worst, AAA 'stuck on local optima because helical movement is too focused on global best that is not necessarily global optima.

Along with the development of information technology, job apangan provided at this time, informed very quickly and have many advantages such as job seekers only open information about job vacancy through websites that have been available. But in the delivery of job vacancy has a constraint that there are parties who have bad intentions by spreading vacancies that are not actually there. So it hurts job seekers, whether material or time. Currently, job seekers do not need to come directly to companies that need jobs but can directly send the application via E-mail. To reduce the act of fraud committed by irresponsible person then needed a system that help job seekers get good information and correct. Therefore, the alternative of the solution is to use a web-based information technology system so that job seekers can directly see and communicate with companies that open job vacancies. In the design of a software system contains job vacancy information and job seeker data processing. The designed software is still a prototype, using Data Flow Diagrams (DFD) and Entity Relationship Diagram (ERD).

Published: February 2020

The main purpose of this research is to compare the response of a modeling and quadcopter implementation when it’s in  normal position and given a yaw-lock mixer input with some PID control parameters. Yaw is one of the movable axis parallel to the axis of the earth magnet. The yaw interference comes from the rotor imbalance as the main inertia generator, thus causing a drift effect on yaw. The yaw-lock mixer input system is installed to keep the yaw in one quadcopter heading position as well as the setpoint tracking. One of the advantages of keeping yaw stability is when mounted dolphin 2 fpv camera axis (roll-pitch), with free-rudder image control generated will consist stable.

The method used in this research are; the quadcopter is dynamically modeled so that hypotheses can be drawn about the quadcopter response. After obtained the quadcopter response formulation, then do the sampling of magnetometer data. Based on the formulation and the sampling data, a decision was made regarding the control technique that became the yaw-lock mixer input to the quadcopter board. The graphic result of reading control response then analyzed the efficiency and the level of "disturbance cancellation".
