Изготовление биметаллических деталей позволяет реализовать в них комплекс эксплутационных и механических характеристик, присущих железоуглеродистым и цветным сплавам. Реализация процесса разрабатываемой технологии формирования биметаллического литья с жестким стальным каркасом и поверхностью из цветных сплавов, обладающих большими, чем материал каркаса пластичностью и электропроводностью, возможна за счет применения модернизированного метода литья по выплавляемым моделям. Изменению подвергается стадия изготовления поверхности выплавляемой модели отливки, которая формируется запрессовкой воскообразного порошка в зазор между пресс-формой и стальным каркасом, что позволяет повысить размерно-геометрическую точность литья за счет устранения теплофизических дефектов. Проблемой в реализации такого подхода является упругий отклик материала. В работе решается задача определения технологических параметров формирования воскообразной поверхности выплавляемой модели биметаллической отливки.

The production of bimetallic parts makes it possible to realize in them a set of operational and mechanical characteristics inherent in iron-carbon and non-ferrous alloys. The implementation of the process of the developed technology for the formation of bimetallic casting with a rigid steel frame and a surface made of non-ferrous alloys, which have greater plasticity and electrical conductivity than the frame material, is possible through the use of a modernized investment casting method. The stage of manufacturing the surface of the investment casting model, which is formed by pressing the wax powder into the gap between the mold and the steel frame, is subject to change, which makes it possible to increase the dimensional and geometric accuracy of casting by eliminating thermophysical defects. The problem in implementing this approach is the elastic response of the material. This work solves the problem of determining the technological parameters of the formation of the waxy surface of the melted model of a bimetallic casting.

Рассматривается динамика одномерных деформаций разномодульной упругой среды под действием нестационарной граничной нагрузки в режиме «растяжение - сжатие». Исследуются особенности построения кусочно-линейной функции, аппроксимирующей нелинейное краевое условие. Указан критерий выбора узловых точек разбиения аппроксимирующей функции, позволяющий управлять режимами взаимодействия волновых фронтов всех типов в решении краевой задачи. Получена итерационная формула изменения скорости ударной волны в результате ее попутного столкновения с медленными фронтами предварительного растяжения, а также итерационные соотношения для построения поля перемещений на всех стадиях деформирования.

The one-dimensional deformation dynamics in an elastic heteromodular medium under nonstationary boundary loading in the  mode is considered. The features of constructing a piecewise linear approximation of a nonlinear boundary condition are investigated. A selection criterion for the nodal partition points of the approximating function is indicated; it allows us to control the modes of collision between wave fronts of all types when the boundary value problem is solved. An iterative formula for the change in the shock wave velocity as a result of its collision with slow fronts of preliminary tension is obtained; the iterative relations for constructing the displacement field at all stages of deformation are written.

Рассматриваются полиметаллические балки постоянного поперечного сечения из наборов упрочняющихся и вязкопластичных материалов с двухсимметричным их расположением в поперечном сечении. Считается, что балки находятся под воздействием нагрузок взрывного типа. Для всех материалов использована модель жестко-вязкопластического деформирования и приняты классические гипотезы деформирования Кирхгофа. Для биметаллических шарнирно-опертых балок получены общие уравнения деформирования и описан метод их решения. Определены остаточные формы динамического повреждения.

We consider polymetallic beams of constant cross-section from sets of hardening and viscoplastic materials with their two-symmetric arrangement in the cross-section. The beams are considered to be subject to explosive loads. For all materials, a rigid-viscoplastic deformation model was used and the classical Kirchhoff deformation hypotheses were adopted. For bimetallic hinged- supported beams, general equations of deformation are obtained and a method for their solution is described. Residual forms of dynamic damage were determined.

Performing radical surgery for locally advanced vulvar cancer is usually associated with the occurrence of large perineal defects. These defects, especially in previously radiated cases, often require more advanced reconstructive techniques using locoregional flaps. We present two cases of vulvar reconstruction, one case using a split and thinned, transversely oriented, pedicled deep inferior epigastric artery perforator (DIEP) flap and another one with gracilis myocutaneous flap. These pedicled flap seems to be an effective and feasible method of perineal reconstruction after extended perineal resection for locally advanced vulvar cancers. especially in pre-irradiated patients.

Objective: Prenatal diagnosis, postnatal followed up of three cases of cardiac tumor and successful postnatal surgery of one case.

Methods: Treatment and postnatal followed up of three cases of cardiac tumor. Those cases were diagnosed by fetal echocardiography. One of them underwent a successful postnatal surgery.

Results: Three fetuses were diagnosed with fetal cardiac tumor (capable of Rhabdomyoma) at 28, 27, 38 gestational weeks. There were many tumors in one or two ventricles. These cases were referred to Hue Central Hospital for timing and location of delivery in 2019. One of them had obstruction of left ventricular outflow tract with successful surgical resection at 46 hours after birth. One of them had heart failure after birth. Evolution of three cases was favorable, heart failure regressed, cardiac tumors regressed at 7 - 9 months follow up.

Conclusions: Fetal cardiac tumor can be diagnosed prenatally. Those three cases were capable of rhabdomyoma due to the presence of muliple tumors and their regression after birth. Neonatal surgical option should be reserved for the risk of cardiac flow obstruction.

Authors: Vu Ngoc Tu
Published: January 2021

Purpose: Compare percent depth dose (PDD) and off-center ratio (OCR) measured by the CC13 ionization chamber and the RAZOR silicon diode in small photon beams.

Method and Materials: Some dosimetric characteristics, such as PDD, OCR, penumbra and radiation field size, were considered in this study for 2x2, 3x3, and 4x4 cm2 field sizes. We used the CC13 ionization chamber and the RAZOR silicon diode to measure dose distribution with depth along the axis and off-center of the beam. From the results obtained, the team investigated the differences in radiation parameters measured by the two types of probes above.

Results: There are significant differences in the radiation parameters investigated for the CC13 ionization chamber and the RAZOR silicon diode, especially the width of penumbra. For PDD curves, the difference is less than 5% from dmax to 30 cm, however the difference becomes greater in the build-up region, which reaches to 33% at the water phatom surface. The width of penumbra measured by CC13 is always larger than that of RAZOR, the ratio of the penumbra width between two detectors is 1.8 and 1.3 for energies of 6 MV and 15 MV, respectively.

Conclusion: The RAZOR silicon diode has better dose response than the CC13 ionization chamber for measuring the PDD and the OCR in small photon beams.

Purpose: To compare the difference of dose distribution and physical characteristics on treatment plans using Three-Dimensional Conformal Radiation Therapy (3D-CRT), Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) techniques in the treatment of lung cancer using Stereotactic Body Radiation Therapy (SBRT).

Materials and method: 9 lung cancer patients who previously underwent with SBRT using VMAT on TrueBeam STx linear accelerator were selected. Average CT obtained from 4 Dimension Computed Tomography Simulation (4D-CT) of patients were used to plan on Eclipse v13.6 by 3D-CRT, IMRT, and VMAT (CP and NCP) techniques. The prescription dose 48Gy in 4 was delivered for the Planning Target Volume (PTV). All plans were optimized and evaluated based on the criteria in RTOG 0915 [1]. The dose distribution of OARs in DVH (Dose Volume Histogram) and the targets at Conformity Index (CI), Gradient Index (GI), Homogeneity Index (HI), Monitor Unit (MU) were used to comparing between conformal and modulated techniques.

Results: Using VMAT and IMRT, the volume conformity was better than 3D-CRT(p<0,01), reduced significant lung dose at V5 (p<0,05). VMAT improved skin dose (23%) than 3D-CRT and IMRT. However, 3D-CRT have much lower MU number than VMAT and IMRT techniques. There were no significant differences in OARs such as the heart, esophagus, spinal cord, chest wall.

Conclusions: VMAT improves the treatment volume coverage and significantly reduces the lung dose volume at V5 than 3D-CRT and IMRT techniques.

Az idegenek szemlélete a japán közösségi érintkezések tükrében

Published: January 2021

There are various expressions in the Japanese language to define strangerswho arrive from the outer world to the community: they are called marebito 稀人, ijin 異人, or gaikoku-jin 外国人 through the history. However, allmembers of the homogeneous community had to approach them with precaution because of the impurity (kegare 穢れ), and other unknown dangersthought to be hiding in them. Therefore, it was a difficult and long process toacknowledge these people who were often banished or stigmatized in spite oftheir efforts of integration. The community itself had several rules to maintain the order between the members and strengthen their social consciousness, which can be seen in today’s Japanese society in regard to tatemae 建前 and the strict courtesy system, too. In present-day Japan, the phenomenonof nikkei-jin 日系人, kikokushijo 帰国子女 or the children born from international marriage arouse new questions related to strangers: who and in whatway can be called Japanese, where can we draw a line between those who aretreated as strangers in spite of their Japanese lineage and the natives who arehighly conscious of their Japanese identity.

Published: January 2021

The Japanese language was greatly influenced by changes of the society andpolitics under the Meiji 明治 Restoration. In this period three new sets oflanguage material became available: stenographic records, audio materialsand newspapers, as well as magazines. The Japanese stenography is basedon English stenography, and its actual implementation began from 1883. Thestenographic records are speeches, lectures, minutes and records of rakugo落語 and kōdan 講談. In the research of the history of Japanese language,stenographic records of rakugo, kōdan and speeches are often used. The rakugo and kōdan materials are large in extent, about 4000 items are known;however, the quantity of speeches and other stenographic records are unknown; therefore, a bibliographic research is necessary in this respect.

The OBOR initiative coversvirtually all geographic areas where key energy supply routes of China arelocated, from sea lanes to existing and planned overland pipelines. Many ofthese regions are, however, scenes of great-power rivalry for geopoliticalinfluence between China and other great and middle powers. Among suchroutes we can mention overland pipelines carrying gas and oil from CentralAsia, as well as strategic sea lanes, such as the Straits of Malacca, wherevirtually all oil imported from the Middle East passes through. This paperendeavours to investigate how these rivalries impact the objectives of theOBOR initiative and the energy security of China, also making distinctionswhich supply routes China will likely be able to secure the most and whichthe least.

Városlakó nomádok 2.0

Due to the rapid transformation of Mongolian social and economic systemin the last two and a half decades, the mentality and way of life of Mongolian people have also changed to a great degree, and a special national or nomadic ideology has appeared and gradually strengthened. It has become oneof the pillars of national identity. This ideology is shared in many respectsby Mongolians. In the present economic environment Mongolian society ischanging at an accelerated speed. The urban population is getting far fromthe nomadic way of life and has started to follow behavioural models thatare very different from the traditional patterns. With the regression of nomadism, one of the fundamental constituents of Mongolian culture seems todisappear. Although in the last 25 years Mongolians have increasingly adaptedto the globalized culture, the need for independent cultural identity is gettingstronger. This identity plays an important role in elaborating economic strategies that are adaptable to the changed environment. It can be observed, forexample, in turnout of shamans in the towns, in the changes of the BuddhistChurch’s social functions or in the “pretended” nomadic lifestyle aroundthe main destinations of tourism.
Kőbe faragott viseletek vizsgálata Banteay Sreiben, Kambodzsában

The objective of my doctoral research is to interpret the meaning of thecostumes of female figural depictions on the walls of Banteay Srei and ofother contemporary buildings erected in the 10th century. This study couldhopefully also shed new light on the hitherto unsatisfactorily solved questionof the dating of the construction periods of the Banteay Srei sanctuary. Thearchitectural and art historical research of Banteay Srei temple has been afundamental topic in Angkorean research for decades. In 2013 and 2014, I spent altogether six months in Angkor to collect allthe data of the carved and sculpted costume depictions belonging to the socalled Banteay Srei style. I established a complete catalogue of more than550 figural depictions found on site on the walls of Banteay Srei templecomplex (including all human and mythological figures which are depictedwith clothes or jewellery), and also other contemporary edifices found currently in Cambodia and Thailand, as well as in different museum collections all around the world. With the help of this database, I interpreted thedepictions in their cultural, religious, architectural and narrative context. In order to achieve my field research it was crucial to obtain an officialresearch permit issued by the APSARA Authority, the state institution thatis responsible for protecting the Angkor monuments. As a result of my personal presentation, I got the generous support of the Authority and I gainedaccess to several sculptural collections, as well as researchers’ and museumcollection databases. The personal collaboration with young researchers working at the APSARA Authority has made it possible for me to visit and document various monuments in remote areas. To access these ruins, we manytimes relied on the local people, mainly kids, even though we were wellprepared and well equipped with modern navigational knowledge and tools.In addition to the scientific documentation, the greatest achievement of theseresearch trips was that I have learned to trust the guidance of the ’local world’.
Taoista nézőpontok a nyelvértelmezésben és értékelméletben I.

The difficulty of translation is particularly relevant in case of the fundamental texts of Daoism, the Laozi 老子 and the Zhuangzi 莊子. During theprocess of translating and interpreting the teachings of Chinese wisdom literature, the conceptual network, if removed from the context of the languagesystem of the original work and conformed with the European philosophical categories, will easily be misunderstood. This study explores the difficulties one faces in the translation of the keyterminology of the Laozi and the Zhuangzi. Based on older and some newtranslations and explanations, I offer some examples when Western philosophical standards, usually deriving from Greek philosophy, cannot beapplied in the interpretation of these Daoist classics, because this would distortthe original conceptual structure and would result in misunderstandings.

It contains several martialart manuals, recording fighting systems of different weapons used by theMing military. Among these fightbooks, there is a fencing manual, which isthe first known recorded description of the fencing system of the Chinesedouble edged straight sword (jian 劍). This paper introduces the fencing manual by investigating its historical and military context, points out its relevance in the study of Chinese military history, and provides the Hungarian translation of the text with commentaries. Based on the example of thejian manual, the article also proposes the application of the interdisciplinaryresearch methods of historical European martial art studies on Ming Chinesemartial art manuals to obtain previously unknown knowledge about Chinesemilitary history.
Fordítva: Nyugati társadalomfilozófiai koncepciók és terminusok „japanizációja” a korai Meiji érában
Authors: Takó Ferenc
Published: January 2021

Today there is a rather broad agreement on the field of Japanese studies regarding the fact that the main political, economic, social and cultural changesthat characterise the Meiji 明治 era have their roots in the Tokugawa 徳川period. This does not mean that changes following kaikoku 開国, the 218 Abstracts“opening of the country”, would have been consciously prepared during theshogunal reign. It means rather that those who reshaped the ideal and materialframework of Meiji period changes, had never torn themselves away fromTokugawa traditions as much as it would seem at first sight, and as much asmany of them suggested they had. In this study I examine the duality of(seemingly) radical novelty and strong attachment to traditions in the age ofbunmei kaika 文明開化 (“civilisation and enlightenment”) as reflected inthe translations of Western social philosophical works and in related theoretical writings of the central figures of the period.

Gyógyítók és gyógyítás a folklór és orvostörténet tükrében a Meiji előtti Japánban
Authors: Papp Melinda , Zentai Judit Éva
Published: January 2021

The present paper is a brief overview of the historical origins of healing inJapan. In the past, the outbreak of a disease was usually attributed to theinfluence of higher spiritual forces. Views on disease and healing weretraditionally influenced by a variety of factors. On one hand, views on lifeand afterlife reflected in popular beliefs defined the way disease was approached. On the other hand, Chinese knowledge of the human body and itsailments penetrated Japan as early as the Heian period. During the Tokugawaperiod spiritual approaches to healing were increasingly combined with moremodern views of the body and official healers and practitioners started toexercise a growing influence on the attitudes of people towards healing andillness. The present paper introduces some of the most significant milestonesin the development of these attitudes through an overview of popular spiritualfigures and deities of healing, and of historical sources documenting theevolution of official medicine.
A fekete hajók előtt
Authors: Szabó Balázs

It is a well-known fact in Japanese historiography that the country was openedup to Western powers by the American Perry expedition in 1853, dubbed inJapan ’the arrival of the black ships’. However, those ships did not comeout of nowhere; there had been various earlier attempts to establish diplomaticand commercial relations with Japan, first by Russia and later by other Westernpowers. These attempts sparked heated debates in Japan regarding the dangercaused by the foreign ships and the best way to avoid this menace. In this paper, after providing a brief description of earlier initiativesaimed at establishing diplomatic relations with Japan, I concentrate on UnitedStates foreign policy vis-à-vis Japan: the USA came into contact with Japanthrough its thriving whaling industry, as in the 1820s US whalers frequentedthe waters close to Japan. Later various economic considerations led to thedecision to organize an expedition to Japan to effectively ensure that Japaneseports would receive US ships and to open the country for commerce. Thesuccess of the US expedition was due to various factors, not least the motivation and determination of its leader, Matthew C. Perry.

In the first part of my paper, I survey the Daoist manuscripts found in thelibrary cave (Cave 17) of Dunhuang. After a brief summary of the textual history of the Zhuangzi 莊子 and its commentaries, I focus on a single manuscriptkept at the British Library (S.796). I offer the transcription and Hungariantranslation of the preserved part of ch. 10 of Zhuangzi, accompanied by thecommentary of Guo Xiang 郭象 (252–312 AD). Furthermore, while concentrating on the so-called Primitivist layer of the Zhuangzi, I give an analysis ofthe figures appearing in this chapter, especially exploring the legendary artisanChui 倕.
Tükör által
Authors: Takó Ferenc
Published: January 2021

In the first part of the present study (East Asian Studies 2017:2) I examined thetechniques used by Meiji intellectuals in translating Western philosophicalterms. In the present paper, I widen the scope of that analysis by examiningthe problems of positioning Japan in the context of what is called “world history” in Western philosophical tradition. This was an extremely challengingtask, as most of the interpretations of Weltgeschichte placed “the East” as suchon the starting point of the historical progress. This idea cannot easily be harmonised with the notion of kokutai 国体, which seemed to be, on the otherhand, a prerequisite of building a Western-like “nation-state” in Japan. In thispaper I examine the ways in which leading Japanese intellectuals such asKatō Hiroyuki 加藤弘之, Mori Arinori 森有礼, Sakatani Shiroshi 坂谷素,Watsuji Tetsurō 和辻哲郎 and Nishida Kitarō 西田幾多郎 handled the tension between the “West” and the “East”, and how Japan was reflected in the“mirror” of the West in their writings.
A Ming-kori katonai víváselmélet leírása és elemzése a Jixiao Xinshu víváselméleti értekezései alapján
Authors: Somogyi Áron
Published: January 2021

The famous 16th century military handbook, Jixiao Xinshu 紀效新書 contains the earliest known surviving treatises on fencing theory in the history of Chinese martial arts. The author, General Qi Jiguang 戚繼光, collected those teachings of fencing theory in the 10th and 12th chapters of the book, considering them necessary in the context of the military application of martial arts. The present paper introduces the difficulties of interpreting the concepts of fencing theory described in Jixiao Xinshu, with a special focus on the problems caused by inconsistent editing, then suggests an interpretational framework that makes it possible give a structured description and analysis of the concepts of fencing theory in Jixiao Xinshu. Finally, placing the sources in the mentioned framework, the paper examines Ming era military fencing theories in detail.
Yamaubamotívumok értelmezése a japán népmesékben és legendákban
Authors: Papp Melinda
Published: January 2021

This article discusses popular yamauba motifs and themes in Japanese legends and folk tales. Yamauba, the Japanese witch, is one of the well-known figures of Japanese folklore. It belongs to the world of monsters and spirits called yōkai 妖怪 that inhabit Japanese myths and legends and that have been explained as personifications of supernatural phenomena originally venerated as deities. A close examination of yamauba motifs shows that yamauba, too, is linked with ancient beliefs regarding fertility and agricultural production as well as with the cult of sacred mountains. In its various appearances, the yamauba, like many other Japanese yōkai, is distinguished by a double character ranging from a fearful monster bringing misfortune to humans to a spirit bringing good luck to those who help her. An analysis of Japanese folk tales thus offers insights into the deeper layers of traditional Japanese folk culture and belief.
