Published: July 2023

Tomatoes are one of the daily necessities for people. In general, consumers favor tomatoes with few seeds. Therefore, there must be efforts made to improve the quality of tomatoes, one of which is to reduce the number of seeds, even if it is possible to make tomatoes without seeds (seedlessness).  By applying Gibberellic acid (GA) during the growth phase of tomato plants, it is possible to enhance tomato quality through technology. The application of GA to certain plants can reduce the number of tomato seeds and increase their sweetness. It is necessary to discover a way to use GA-containing natural ingredients to prepare for the high cost of synthetic GA. Onions are one of the natural ingredients that contain GA. Thus, this study aimed to examine the effect of applying onion extract as a source of GA to obtain the optimum concentration of onion extract that can improve the quality of tomato fruit. The experimental design utilized Randomized-Group Design with five different treatments: no spraying, spraying with 25%, 50%, 75%, and 100% onion extract. According to the findings, the application of onion extract improved the quality of tomato fruit. This condition is reflected by a decrease in the number and weight of seeds per fruit and an increase in the fruit's vitamin C content. Therefore, it is essential to conduct this research to produce inexpensive, high-quality tomatoes to sustain the economy and increase farmers' income

The city of Syganak was recognized as one of the major political centers in the middle reaches of Syrdarya in the 11th and 16th centuries. The city was one of the main centers of the Kypchak Khanate, the White Horde, the Abulkhair Khanate and the Kazakh Khanate. For this reason, the rulers of the above-mentioned khanates, famous personalities were buried near the city. The huge mausoleums were built for demand the city became one of the sacred and spiritual centers. The mausoleum – a monument of architecture, built on a grave or cemetery. The mausoleums were considered as the afterlife home of the deceased. According to the constructions of the mausoleum it is possible to determine the social level of people, buried in the mausoleum or to which class they belong. The identified burial grounds and the found objects allow to determine the status, level of social development, worldview, lifestyle, traditions, religious beliefs, funeral rite and social relations of ancient people. The authors set the goal to study, analyze and introduce into scientific discourse the mausoleums №6 and №7, discovered during archaeological excavations in the medieval city of Syganak in 2022. In addition, the authors consider it is important to determine the history of the creation and development of mausoleums. Basing on the results of archaeological research, conducted in the city of Syganak in 2022, the absolute chronology of the mausoleums was determined using the analysis C14, similarities and differences with the same type of mausoleums in neighboring regions were discussed, scientific observations were carried out.

The author discusses the structure which is stone mound. Inside it the remains of a campfire were found containing a complex of finds. The object was found on the hillfort near the village of Gora Uslan, located on the left bank of the Upa River, within the boundaries of the city of Tula. Due to the absence of human remains, this complex does not belong to burial sites, but is associated with memorial rites. On the basis of analogies, the complex of finds can be dated to the second half of the 7th–8th century. The buckle from the campfire has analogies in the mordovian burial grounds. The find of a miniature handmade jug is connected with the steppe antiquities. The handmade vessel found at the foothill of the mound is close to “Sakhnovka” type materials. Similar objects on the territory of the Oka-Don watershed and adjacent regions are not known. Structurally and functionally the most similar constructions are known in nomadic antiquities of the Samara Volga region of the 7th–8th centuries. The cultural syncretism of the published complex demonstrates of complicated the ethno-cultural situation in the region during the second half of the 7th –8th centuries.

The article presents the results of studies carried out in the south-eastern part of the Bolgar fortified settlement in 2013. The Golden Horde objects belonging to different periods have been identified here. Since early coins make up more than 10% of the numismatic collection, this suggests that the site began to be developed already in the 2nd half of the 13th century. The pits in the southwest corner of the excavation can be attributed to this time. Unique are the finds of two dinars of the 12th century and the middle of the 13th century, belonging to the initial stage of the development of the area. А wooden house (structure No. 2) with a kang was built on the site within the period from the 2nd half of the 13th century to the 1230ies. Probably, the construction of three pits with large poles is related to the time of the wooden house, as well as, perhaps, a stockade. The building was destroyed by a fire. The next construction period is associated with a stone building (structure No. 1), soon erected on the place of the burned house. According to the coins found here, the stone building with a kang was built here no earlier than in the 1340s and functioned until the 1360s. The horizon of the building of a stone house is marked by layers of construction debris that filled the most of the pits on the excavation. The stone masonry of the building was almost completely taken and used as building materials, most likely already at the beginning of the 20th century, but the well-preserved contours of the foundation trenches, densely filled with lime and stone fragments, allow us to restore the layout of the building. The portal of the building, located on the north side, was decorated with two pylons, that were the base of the arched entrance, and a square construction, probably a turret, sided with the western one. The uniqueness of the building consists in an amazing combination of features of private residential and public architecture. After the 1360s, the site became desolate, and this wasteland was used as a cemetery: near the remains of a stone building the burials with fragments of its architectural details in the filling were found. The studied estate was related geographically with the quarter of the "Mongolian administration" at the Small Minaret, where dwellings with kangs were concentrated.

The materials obtained during the work on the complex of mausoleums of the Golden Horde era near the village of Lapas in the Astrakhan region by the Volga archaeological expedition led by V.V. Dvornichenko in 1995 – 1997 are introduced into scientific circulation. These were the first scientific studies of the largest cult complex of the Golden Horde nobility, little known in the scientific community. It was then that the idea of the true size, composition and potential of the archaeological monument, its significance in the culture of the Golden Horde and the development of Islam in the Eurasian space appeared.

Significant changes took place after its incorporation into the Russian state in the culture of life support of the aboriginal population of Western Siberia in the 16th century. The achievements of Russian civilization have been perceived and adapted to their needs: more advanced economic subject complexes; new technologies and branches of the economy that have allowed improving the quality of life and creating a more comfortable living environment. These processes have been studied within specific territories and individual monuments (both settlement and burial) but have never been analyzed as a whole for the entire region. An attempt to consider the results of the impact of Russian civilization on the cultures of indigenous peoples is presented in the article. The main source was archaeological materials reflecting various spheres of life of the population, costume and household complexes, spiritual culture. Conclusions are drawn that, despite the positive impact of the acquired innovations, the aboriginal population has preserved the traditional household culture, although to varying degrees.

The authors consider the easternmost finds of toreutics of the "Hungarian style" from the archaeological sites of the Yudino culture of the forest Trans-Urals. An analysis of the materials showed that these products appeared in the Trans-Urals after the ancient Hungarians had migrated to the territory of the Carpathian basin. The "Magyar" group of items occured in the closed complexes of the Trans-Urals together with the imported items from the Upper Irtysh River region, Altai, the Upper Kama River region and the Southern Urals. Therefore, the authors assumed that the products of the "Hungarian style" got in the Trans-Urals at the end of the 9th–10th centuries as a result of trade relations. Most likely, the transfer of imports was not carried out directly from the Carpathian groups to the Trans-Urals, but through the mediation of the Eastern European population.

This article for the first time reproduces and comprehensively interprets the data of excavated memorial enclosures of the early Middle Ages on the territory of Semirechye – southeastern part of Kazakhstan. Two memorial complexes of Karakystak 18 and Ulken Kakpak essentially complement the corpus of similar excavated monuments of Semirechye. The analysis of both constructive features of the memorial monuments and accompanying inventory is undertaken. Finds of ceramic fragments from three different vessels near the enclosure No. 2 of Ulken Kakpak may indicate intentional damage of vessels after the memorial ritual in honor of the deceased. Using the comparative study with similar archaeological objects from the territory of Sayan-Altai and Mongolia we assume the dating of these memorial enclosures in Semirechye in 8th–10th centuries. The authors concluded that the memorial enclosures on the territory of Semirechye have a much smaller variety of constructive features than similar objects in South Siberia and Central Asia. The memorial complexes in Karakystak and Ulken Kakpak could have been created both by the Turks of the "ten arrow’s" Western Turkic Qaghanate and more probably by the Turgesh or Karluks.

The article presents the publication and diverse interpretation of materials from the excavations of the enclosures of the Ak-Dag complex, located in the Erzin district of the Tuva Republic. The objects under study were investigated by the archaeological expedition under the leadership of M.Kh. Mannay-ool in 1961. Despite the importance of the information obtained during the excavations, these data were not published and were not used in the development of well-known concepts of the history of the region. The article provides a detailed description of the studied enclosures, as well as an analysis of the fixed features of structures, elements of ritual practice and inventory items. It has been established that the dating of objects can be determined by the framework of the second half of the 5th – 6th centuries AD with the possibility of narrowing the chronology, taking into account the known historical context, to the middle – the second half of the 6th century AD. The Ak-Dag enclosures, as well as other, so far a very few complexes of Tuva of this period, testify to the emergence in this region of a new population group, close in tradition to the Altai nomads. There is every reason to assert that these processes are associated with the military campaigns of the Turks, which led to the creation of the First Khaganate.

Abstract
Background: Acne vulgaris is a common cutaneous disorder caused by chronic inflammation of the sebaceous glands. It is characterized by the presence of open and closed comedones, oily skin, pimples, and scarring. It mainly affects skin with numerous oil glands, including the face, chest, and back. The risk factors for acne include genetic, hormonal, and lifestyle factors. Although acne is a benign condition, it has a worldwide prevalence of approximately 10%. Herein, we aimed to study the prevalence of acne vulgaris and its association with lifestyle in the general population.
Methodology: This cross-sectional study used a self-administered electronically distributed questionnaire to assess the association between acne vulgaris and lifestyle among the general population in the Jazan region.
Results: A total of 462 residents of Jazan responded (270 females [58.4%] and 192 males [41.6%]). The mean age was 25.52 years (SD = 7.7). Approximately 63.6% of our respondents suffered from acne, which affected the cheeks (75.9%). Acne was significantly associated with skin type, use of facial cleansers, BMI, family history, stress, and fast food intake. However, 64.6% of the respondents did not visit a doctor for acne. Furthermore, 25.9% of the respondents did not use any medications, whereas 31% used topical medications.
Conclusion: Approximately two-thirds of the study participants had acne. Therefore, more efforts are needed to assess the cause of the high prevalence of acne in our region and to determine the related risk factors to minimize its incidence by conducting educational programs.

In the research, we successfully investigated effects of calcination temperature on the characteristics and photocatalytic activities of WO3 applying for degradation of antibiotics in aqueous environment under visible light. The crystal phases and optical properties of the synthesized WO3 nanoparticles were determined by an X-ray diffractometer (XRD), an UV-VIS diffuse reflectance spectroscopy (UV-VIS) and a photoluminescence spectroscopy (PL). The photocatalytic activities of the WO3 materials, which were calcinated at different temperatures, were studied via degradation of Tetracycline under visible light. Obtained results indicated that the orthorhombic phase was converted completely to monoclinic phase when the sample was calcinated at 500 oC. As compared to these WO3-300, WO3-400 and WO3-600 samples, the WO3-500 sample, which was calcinated at 500 oC, showed significant decrease in band gap energy and electron-hole recombination rate. Thus, the WO3-500 exhibited novel photocatalytic activity for Tetracycline degradation under visible light.

Keterkaitan antara Halitosis dengan Bakteri Penyebab Periodontitis
Authors: Astuti Luki , Nauli Komala Olivia
Published: July 2023

Halitosis, often known as foul breath, refers to an unpleasant odor that emanates from the mouth cavity when inhaling or talking. Halitosis can have a negative impact on a person's quality of life, including symptoms of depression or anxiety, low self-esteem, embarrassment, prejudice, and social isolation. Bad breath can be caused by both intra oral and extra oral factors. Bacterial growth in the oral cavity is excellent for the production of volatile sulfur compounds (VSC). The posterior dorsum of the tongue, gingival sulcus, periodontal pockets, and gingival embrasures are all places where bacterias can accumulate. Fusobacterium nucleatum, Prevotella intermedia, Porphyromonas gingivalis, and Treponema dentiocola are known to actively produce VSC through interactions with specific substrates such as cysteine, methionine, tryptophan, arginine, and lysine to produce hydrogen sulfide (H2S) and methylmercaptan (CH3SCH3). However, the presence of VSC does not indicate the presence of periodontitis, as any space in the oral cavity that can cause the retention of bacteria/biofilms can become a site for bacterial decomposition, thereby facilitating the growth of VSC. Tongue cleansing is proven to help reduce the formation of VSC.

Background: Cefadroxil, betalactam antibiotic belonging to cephalosporin class, is a drug of choice for treating periodontal infection. Previous studies reported that addition of green tea (Camellia sinensis) extract to betalactam antibiotics has shown synergistic antibacterial effect. Objective: To examine the antibacterial effect of GTE combined with cefadroxil on A. actinomycetemcomitans and P. gingivalis growth. Methods: In vitro experimental with post-test-only control design, conducted at MiCORE Laboratory, Trisakti University Faculty of Dentistry. There were 8 treatments: combination of cefadroxil 8 µg/mL with GTE 3,125 mg/mL, 6,25 mg/mL, and 12,5 mg/mL, GTE 3,125 mg/mL, 6,25 mg/mL, and 12,5 mg/mL, cefadroxil 16 µg/mL, and NaOH 0,1 N. Results: In treatment of solely GTE and NaOH 0,1, no inhibition zones were found. Meanwhile, combination of cefadroxil 8 µg/mL with GTE 3,125 mg/mL, 6,25 mg/mL, and 12,5 mg/mL, and cefadroxil 16 µg/mL inhibited both bacteria’s growth. Treatment of cefadroxil 8 µg/mL combined with GTE 3,125 mg/mL resulted in the largest inhibition zone. One-way ANOVA test showed significant difference, then post hoc test showed that combination of cefadroxil 8 µg/mL with GTE 3,125 mg/mL and 6,25 mg/mL were not significantly different from the positive control. Conclusion: Potentiation effect occurred on combination of cefadroxil 8 µg/mL with GTE 3,125 mg/mL and 6,25 mg/mL against A. actinomycetemcomitans and P. gingivalis growth. Green tea extract could increase cefadroxil antibacterial effect up to twice larger.

Published: July 2023

A periodontite é uma doença infecto-inflamatória associada ao biofilme disbiótico que afeta os tecidos de proteção e de suporte dos dentes. O processo inflamatório que ocorre durante a periodontite tem sido associado à inflamação sistêmica em pacientes com doença renal crônica. Os polimorfismos genéticos são alterações no DNA que podem ter classificações diferentes dependendo da mutação gerada, e podem ser criados ou destruídos. Objetivo: O objetivo desta revisão sistemática da literatura foi elucidar a seguinte questão: os polimorfismos genéticos estão associados à doença renal crônica e à periodontite? Material e Métodos: A pesquisa foi realizada no PubMed, Biblioteca Cochrane, EMBASE, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Bibliografia Brasileira de Odontologia (BBO), Biblioteca Virtual em Saúde (BVS), SciELO, Scopus, Web of Science e bases de dados de literatura cinzenta (Google Scholar) sem restrições de data ou idioma em 28 de junho de 2021 e atualizada em 26 de janeiro de 2023. Os descritores padronizados (Medical Subject Headings, MeSH) utilizados foram: "polimorfismo genético", "doença renal crônica" e "periodontite", de acordo com o banco de dados consultado, utilizando os operadores booleanos "AND". Resultado: 25 publicações foram identificadas. Após a análise do título, do resumo e do texto completo, 6 estudos de caso-controle foram selecionados para análise. Todos incluíam artigos investigando o papel de diferentes polimorfismos genéticos em ambas as doenças. Alguns genes apresentavam uma relação próxima com o perfil inflamatório que caracteriza ambas as doenças. Conclusão: Entre os polimorfismos estudados, os polimorfismos VNTR no gene IL4 e MCP-1-2518 A/G apresentaram uma associação positiva tanto com a periodontite quanto com a doença renal crônica. Entretanto, são necessários mais estudos para melhor compreensão do papel dos polimorfismos genéticos nessas doenças.

No desenvolvimento da ferramenta foi adotada como estratégia metodológica a abordagem quali-quantitativa composta pela revisão sistemática de trabalhos correlatos e análise dos portais de egressos para identificar como as IES brasileiras realizam o relacionamento com seus egressos. A adoção desta abordagem tornou possível estabelecer as funcionalidades que deveriam estar presentes na ferramenta comprovando a convergência entre estas etapas e os requisitos especificados para a sua implementação. O método utilizado no desenvolvimento da ferramenta possibilita sua utilização por todas as IES que tenham interesse em ampliar as informações sobre os seus egressos mediante ajustes pontuais do software às Tecnologias da Informação de cada Universidade. A ferramenta disponibiliza, dentre outras, funcionalidades que permitem a extração online e automática de informações dos sistemas acadêmicos das Instituições assim como dos Currículos Lattes, análise de indicadores da produção acadêmica dos pesquisadores, investigação do progresso acadêmico e profissional dos egressos por meio de pesquisas propostas pelos gestores que podem contribuir com as tarefas de gestão da Pós-Graduação Stricto Sensu.

Responsive Measures for Youth Development to Prevent Delinquent Behaviour Among Youths Not in Education, Employment or Training
Authors: Chauke Thulani Andrew
Published: July 2023

In this article, I sought to explore the perspectives of young people who are no longer in the education system and who are not working or being trained for work (NEETs) of youth development interventions that can be used to prevent delinquent behaviour among youths residing in the Cape Flats, South Africa. In this regard, convenience and purposive sampling were used to sample 30 NEETs, aged 18 to 24 years. Unstructured qualitative interviews were used to collect the data, and a thematic analysis was used to analyse the data that were collected. The findings revealed that the institutionalisation of youth clubs in the Cape Flats could be the best type of intervention to prevent youth delinquent behaviour. In this article, I recommend a multisectoral approach that would involve joint efforts from civil society and the government with the already existing basic package of support for empowerment of NEETs to strengthen the Presidential Youth Service Programme.
Strengthening Family Connectedness: Experiences of Families with Children with Behavioural Problems
Authors: Danhouse Merle , Erasmus Charlene J
Published: July 2023

Children’s behaviour is influenced by their family’s surroundings, interactions with their parents, and the connectedness that they experience within their family. Positive behaviour in children develops when they feel loved, supported, and safe in the presence of their parents. A weakened parent-child bond may lead to child behavioural problems and impact the ability of parents to create a positive social learning environment. The aim of this study was to explore the experiences of families with children presenting with behavioural problems (FCBPs) in strengthening family connectedness. A qualitative research approach was used where semi-structured interviews were conducted with 10 parents of children aged two to 18 reported to be presenting with behavioural problems. Thematic analysis was used to analyse the data, giving rise to three themes: 1) understanding family connectedness; 2) parenting children with behavioural problems; and 3) family, community, and social work interventions. The findings of the study showed that FCBPs find it difficult to strengthen their relationships with their children. Their parenting capabilities are challenged when they have a strained relationship with their children presenting with behavioural problems (CBPs). The frustration of parents in the study was heightened by limited support received from family, community, and spouses, impacting their ability to strengthen the connectedness in the family. The study recommends that parents receive specialised social work intervention to learn new skills and strategies to strengthen their relationships and cope with the behaviour of their children. Furthermore, this study recommends that social workers receive training to deal with the risky behaviour of children and to support parents to strengthen their relationships with their CBPs.
Anesthetic challenges in a patient with Hirayama disease with quadriparesis and autonomic dysfunction undergoing cervical spine surgery
Authors: Reddy Ashwini , Varma Prerna , Barik Amiya Kumar , Narayan Vinitha
Published: July 2023

Hirayama disease is a rare neurological disorder, characterized by muscular atrophy of the distal upper extremities. The occurrence of spastic quadriparesis and autonomic dysfunction is rarely reported and has important perioperative considerations during cervical spine surgery for the treatment of this disorder. The role of the anesthesiologist is vital in the thorough assessment of the patient for the involvement of the pyramidal tract, autonomic dysfunction, gastroparesis, hyperreactive airway disease, and documentation of neurological deficits. Intraoperative concerns include safe manipulation of the airway during mask ventilation and the use of a flexible fibreoptic bronchoscope during endotracheal intubation to prevent neck flexion. It is also essential to avoid drugs, leading to histamine release. The use of multimodal monitoring including bispectral index and neuromuscular monitoring is crucial to prevent delayed recovery. Anticipation and management of exaggerated hypotension in response to anesthetic induction agents and prone position is the key to a successful outcome in patients with autonomic dysfunction.
THE BRONZE CAULDRON FROM KURGAN 4, KRASNOSELSKAYA 9 KURGAN GROUP (KRASNODAR KRAI)
Authors: Демиденко С.В. , Левин Е.С. , Лунев М.Ю.
Published: July 2023

В 2020 г. Западно-Кавказская экспедиция исследовала курганную группу Красносельская 9. В кургане 4 был обнаружен разбитый бронзовый котел. По морфологическим и технологическим признакам он относится к большой группе бронзовых литых котлов, широко распространенных на территории Среднего Енисея, но которые не встречаются в южнорусских степях и на Северном Кавказе. Японская исследовательница Хатакеяма Теи выделяет данные сосуды в тип I 1 Abii и датирует их V-IV вв. до н. э. Практически идентичный бронзовый котел был найден в дромосе к5 п2 курганного могильника «Высокая Могила - Студеникин Мар» курганной группы № 4 «Богатырские могилки» в Южном Приуралье. Исследуемый нами котел, вероятно, также относится к IV в. до н. э. и маркирует на сегодняшний день самую юго-западную точку распространения котлов «сибирского» типа. Котлы данного типа доживают на территории Южной Сибири до II-I вв. до н. э. Возможно, этот экземпляр попал в курган гораздо позже основного периода бытования, поскольку обычай помещения в погребальное сооружение обломков котла наиболее часто фиксируется у сарматских племен в I в. до н. э. - первой половине II в. н. э.

In 2020 the Western Caucasus expedition excavated the Krasnoselskaya 9 kurgan group. Kurgan 4 contained a broken bronze cauldron. Based on morphological and technological features. it is referred to a large group of cast bronze cauldrons which were widespread in the Middle Yenisei region but are not found in the southern Russian steppes and the North Caucasus. The Japanese scholar Hatakeyama Tei singles out these vessels into type I ‘1 Abii' dating them to the 5th-4th centuries BC. A practically identical cauldron was found in the dromos of grave 2. kurgan 5. at the Vysokaya Mogila - Studenikin Mar kurgan ground of Bogatyrskiye mogilki kurgan group 4. in the South Urals. The cauldron in question is likely to be dated to the 4th century BC. Thus it marks the south-westernmost point of the area where the ‘Siberian' type of cauldrons was spread. This type of cauldrons was in use in South Siberia until the 2nd-1st centuries BC. The said cauldron might have got into the kurgan much later than the period when such cauldrons were commonly used since the custom of placing cauldron fragments into a burial construction is most frequently recorded among the Sarmatian population groups during the 1st century BC - first half of the 2nd century AD.
SEL’TSO CEMETERY: THE MISSING LATE VIKING AGE NECROPOLIS IN THE VICINITIES OF SUZDAL

Современный научный интерес к средневековым некрополям центральных районов Суздальской земли обусловлен как значимостью их для изучения культурно-исторических процессов X-XII вв. на северо-востоке Руси, так и спецификой их поиска и документирования в ситуации, когда на местах могильников уже нет курганов, служивших для археологов ориентирами для выбора мест раскопок. Возвращение к исследованию этих памятников предполагает обновление привычных приемов полевых работ: привлечение ГИС-технологий для привязки планов и карт XIX-XX вв., широкое использование геофизической разведки, систематический поиск и сбор средневековых артефактов из разрушенных погребений на современной поверхности. Неразрушающие методы полевых работ существенно меняют общее видение погребальных памятников средневековой Руси, в том числе их пространственной структуры. Коллекции из сборов на площадках некрополей становятся важной частью общего массива данных, характеризующих культуру Северо-Восточной Руси X-XII вв. В настоящей статье публикуются материалы новых работ на могильнике Сельцо, считавшемся полностью изученным после раскопок середины XIX в.

Current research interest to medieval burial sites of the central part of Suzdal land developed due to their basic significance for the studies of North-Eastern Rus' formation and cultural identity, but also due to the demand for special approaches to the search and investigation of the burial sites in the modern landscapes, in the situation when the kurgans were leveled and visible marks of medieval graves are lost. New phase of research at these sites assumes revision of the traditional forms of field investigations: implementation of GIS-technologies for the integration of the field documentation of the former works into modern digital data sets, wide-scale geophysical prospections, systematic search and recording of medieval artefacts from the disturbed burials, now dispersed over the surface. Non-destructive techniques considerably change general vision of Medieval Rus' burial sites, including their spatial structure. Artefact collections obtained through the surface surveys at the cemeteries become an important part of the general corpus of archaeological data relating to Medieval North-Eastern Rus'. The paper presents the results of recent investigations at the Sel'tso cemetery, which was regarded as completely exhausted after the excavations conducted in mid XIX century.
THE 14th–15th CENTURY BUILDINGS IN THE SETTLEMENT OF MILSEN

Published: July 2023

Статья посвящена атрибуции и установлению конструктивных черт 16 объектов XIV-XV вв., выявленных при исследовании поселения Мильзен (совр. Холмы) в 2010 г. Центральное место среди них занимает подпольная яма наземной каркасно-столбовой постройки (объект 9), от ограды которой сохранились столбовые ямы ворот (объекты 14а и 15а) и дорожка между ними (объект 12). Остальные 12 объектов представляли собой ямы преимущественно овальной и прямоугольной форм, имевшие хозяйственное назначение. Выявленные объекты частично или полностью разрушили погребения грунтового могильника XI-XIII вв., расположенного на этой же территории. В подполе жилой постройки и хозяйственных ямах помимо переотложенного инвентаря нарушенных погребений были обнаружены полные формы и фрагменты круговых глиняных сосудов, относящиеся к периоду функционирования построек. Их основную часть составляли мореные сосуды из красножгущейся глины, представленные двумя полными формами кувшинов и 61 фрагментом. Схожие сосуды найдены в городах государства Тевтонского ордена (Альт-Вартенберге, Лёбинихте, Эльбинге) и происходят из германских земель, что, наряду с расположением построек на могильнике, говорит о переменах в культуре местного населения в XIV-XV вв.

The article is devoted to the attribution and determination of constructive things of 16 objects dated by the 14th-15th centuries that found by the research of settlement Milsen (Kholmy) in 2010. The central place among them has underground pit from a ground frame-pillar building (object 9) from fence of which preserved pillars pits of the gate (objects 14a and 15a) and the path between them (object 12). Another 12 objects were utility pits of in general oval and rectangular shapes. Researched objects partially or completely destroyed objects from the ground burial dated by the 11th-13th centuries and situated on the same territory. In the underground pit of living building and in utility pits were found besides inventory from destroyed burials also whole ones and fragments of clay vessels from a pottery kilns dated by the time of function of the objects. The main part of them are 2 intact jugs and 61 fragments of pottery vessels produced in reduction atmosphere. The same vessels were found in the cities in the State of Teutonic Order (Alt-Wartenberg, Lobinicht, Elbing) and originate from German lands that as well as location of settlement on the territory of ground cemetery marks the changes in the culture of local population.
