The Influence of International Migration on Demographic Indicators in the Republic of Moldova at the Current Stage
Authors: Daud Tatiana
Published: December 2018

The study of international migration effects has become essential at this stage. Thus, the Republic of Moldova was touched by the massive migration phenomenon, being hit by a huge wave of emigration, the main cause being the economic situation in the country. In this article, the author correlates three complex phenomena: migration, demographic indicators and socio-economic stability in the Republic of Moldova. The study will analyze the demographic consequences from the historiographical and theoretical-methodological perspective, all the more so since the category of emigrants for economic reasons in recent years is composed of young people (around the age of 35). Consequently, the Republic of Moldova faces an accelerated process of its own population aging. The most serious problem, however, is the temporary abandonment of minors by migrant parents, and national authorities must develop policies to monitor them, which are often inefficient or do not meet European standards.
The multidimensional approach is taken to the concept of migration in terms of its impact on the demographic indicators and the prospects for settlement. The tendency to remain definitive in the destination country is well known and leads to considerable losses among the population. This loss results in a decrease in the economic growth rate, but at the same time social one, because the human factor is the most important source of economic growth. It is estimated that by 2040 more than one billion inhabitants of the planet will leave their place of origin to seek their place elsewhere. Such an evolution is objective and corresponds to advanced economic and social characteristics, especially in European areas. Developed economy, guaranteed jobs, respected human rights, full affirmation, especially among women, as well as a cultured society have contributed to the increase of Moldovan citizens' emigration.
The article aims at a preliminary analysis of the relations between the components of international migration and the dynamics of the Republic of Moldova's population.
In conclusion, the author points out the dependence on the economic, social, cultural and political advantages of Moldovan citizens, as well as the achievements and reforms of the national authorities in the process of European integration. In the absence of the political actors' awareness of the demographic crisis in the Republic of Moldova, the negative demographic forecasts for the coming years will be difficult to alleviate. To this end, to take the necessary actions and measures or to promote policies to stop this phenomenon, the negative effects identified in the emigration can be corrected and resolved.

Threats and Challenges for young European Countries in New International Conditions, Using Ukraine and Moldova as a Case Study
Authors: Russu Roman
Published: December 2018

Several mounts ago, during emergency meeting of UN Security Council, General Secretary Antonio Guterres, made a very trebling statement, that Cold war is back and it is even more dangerous than in the 60’s.This is not news for majority of scientific community. New international conflict started in 2014 when Russia annexed Crimean peninsula. New international conflict will definitely change the balance in international relations.The most vulnerable in these new conditions are the young democracies and countries that formed several decades ago due collapse of USSR and the whole communist bloc, Ukraine, Moldova, south Caucasian and Baltic states. Imperial past left a lasting mark on economical, social and political life of newly form states. Soviet social experiments led to good number of problems for the former republics, ranging from political to territorial.Russian Federation uses these problems for her advantage. Surviving in this harsh conditions and reforming their society is the main challenge of young European countries.
Придністровський конфлікт 1992 року та російська агресій проти України: компаративний аналіз
Authors: Филипенко Артем
Published: December 2018

У статті представлений компаративний аналіз придністровського конфлікту 1990-1992 років та українсько-російського конфлікту 2014-2018 рр. Проаналізовані схожі риси та відмінності двох конфліктів. Доведено, що сценарій, за яким розвиваються події на Донбасі, дуже схожий з подіями в Придністров'ї в 1990-1992 роках, зокрема, через використання мовної проблематики для виникнення протистояння, надання воєнної та політичної підтримки, у тому числі, через залучення іррегулярних формувань, безпосереднє втручання збройних формувань регулярної російської армії у бойові дії.Особлива увага приділяється методам інформаційної війни, яка велася проти Молдови на початку 90-х. Показано схожість цих методів із такими, що застосовуються Росією у інформаційній війні проти України, зокрема, 1) дегуманізація противника,поширення відомостей про його жорстокість і нелюдяність2) маніпуляція історичними фактами 3) представлення боротьби із сепаратизмом як агресії однієї держави проти іншої 4) апеляція до подій Другої Світової війни 5) наголошення на тому, що на боці урядових військ воюють іноземні військові 6) намагання представити сепаратистські рухи як "народні".У висновках наголошується, що придністровський конфлікт 1990-1992 рр., так само як окупація Криму та конфлікт на Сході України в 2014-2018 рр. є частиною загальної стратегії Росії щодо збереження Республіки Молдова та України в сфері свого впливу. Кінцевою метою цієї стратегії є реінтеграція сепаратистських анклавів на умовах, які вигідні Росії, а саме: можливість впливати на зовнішню політику, зміна зовнішньополітичних пріоритетів (відмова від курсу на європейську і євроатлантичну інтеграцію), збереження залежності від поставок російських енергоносіїв.

Authors: Gribincea Alexandru , Gribincea Corina
Published: December 2018

By progressing technological and scientific revolution it enters in various fields of the economy. The banking sector is able to compete with large high-tech companies, online banks ensuring effective and inexpensive communication with customers. The banking sector in the future will compete with large high-tech companies such as Facebook or Amazon, considering online banks on the forefront of the competitive fight due to efficient interaction with the customers and lower costs. The main difference between online banks and traditional is the absence of large office network: interaction with customers is mainly realized through websites, mobile banking, social networks or by phone. These banks usually develop their own high-tech platforms. Since the last decades, Moldovan banks have aligned their activities with the new legislative framework in relation to the implementation of Basel III standards by implementing the CRD IV package, which will be implemented in stages by 2020. At the same time, the National Bank of Moldova continues the process of promoting the banking sector reforms, focusing on shareholders 'transparency to attract new investors to meet higher quality requirements, establishing strong corporate governance in the banking sector, identifying bank affiliates and timely reflecting unfavorable loans in banks' balance sheets. The IT Park is set up in Moldova. The main objective of the initiative is to accelerate the development of the IT industry by accelerating the implementation of technologies in various fields, opening new jobs, attracting both internal and external investments and specialists. The concept of the Moldova IT Park model claims to be an ambitious and landmark project for the development of other areas; a community that will grow every year, to which new companies and projects will join and who will make new successes. All project actors want Moldova IT Park to become a useful and efficient project offering rich digital content and advanced information services, which in turn will increase the level of economic competitiveness and welfare of the population. Lately we witness spectacular changes in banking services. The banking system cooperates with IT companies to gain a competitive advantage. Thus, any bank is able to develop and deliver innovative solutions to consumers, streamlining the work and concept of banking services. These innovations offer unprecedented opportunities in financial activity. In the future, banking cards will be excluded, bank cards, branches and subsidiaries will be optimized, and banks will turn from service / product vendors to developers of consumer options and dreams. Any whim and transaction will be possible from any corner of the Earth.This research aims to elucidate trends in the global banking market and prospects for the Moldovan market.
An Overview of the Further Demographic Situation and Economy in 2035
Authors: Gribincea Alexandru
Published: December 2018

The study of the situation in Europe and other countries in the context of demographic evolution, the forecast of economic development has shown that the population, structural migration and economies are closely correlated. The population and economy in the EU in the near future will undergo dramatic changes. In some developed, industrialized countries, the population grows slowly or stagnates, while in economically poor economies, birth rates are accelerating, and as healthcare increases, it will lead to a demographic explosion. In recent years, the EU population has grown by 507 million, with a projected increase of 5% by 2050, reaching a maximum of 526 million, after which it will decrease to 523 million in 2060 yr. In about half of the EU countries, despite the population growth trend, the total population will diminish. This trend refers to Bulgaria, Germany, Estonia, Greece, Spain, Croatia, Lithuania, Latvia, Poland, Portugal, Romania, Slovakia and Slovakia. In total, decline of population in Eastern European countries is linked to a number of factors. First is the reduction of the socio-economic level of the population, increasing labor migration to countries with advanced living standards. In these countries, as a rule, the standard of living, social and medical assistance, social protection is reduced. At the same time, world community is going through a difficult time. A deep and prolonged recession that followed the global financial crisis has changed with the slow recovery of employment.Never in the history of mankind, the growth rate of the world population was not as large as in the second half of the 20th and early 21st century. Between 1960 and 1999, the population of the planet doubled (from 3 to 6 billion people), and in 2007 - 6.6 billion people. Although the average annual growth rate of the world's population declined from 2.2% in the early 1960s to 1.5% in the early 2000's absolute annual growth increased from 53 million to 80 million people. Demographic changes from traditional (high fertility - high mortality - low natural growth) to the modern reproductive population (low fertility - low mortality - low population growth) ended in developed countries in the first decade of the 20th century, and most of the transition economies - in middle of last century. At the same time, in the 1950s and 1960s, the demographic transition began in several countries and regions of the rest of the world and begin to the end only in Latin America, East Asia and Southeast Asia and continuing in East Asia, Africa Sub-Saharan Africa from the Sahara to the Middle East. Rapid population growth compared with the indicators of socio-economic development in these regions leads to aggravation of problems related to employment, poverty, food, land, low education and health risks.

PEGMATITES AS A SOURCE OF RARE-METAL AND RARE-EARTH MINERALIZATION WITHIN THE CENTRAL AND WESTERN PARTS OF THE UKRAINIAN SHIELD
Authors: Vasylenko A. P. , Isakov L. V.
Published: December 2018

Regularities in the distribution of rare-metal and rare-earth pegmatites within the Western and Central parts of the Ukrainian shield are determined. New geological criteria and search signs for rare-metal and rare-earth mineralization have been developed. The first group includes the forecasting criteria that are tied to the general patterns of location of pegmatites in time (geochronological) and space (megastructural). These criteria define the main structural units (pegmatites provinces, regions, districts) and their metallogenic specialization. The second group combines regional criteria among which are distinguished tectonostructural, magmatic and metamorphic. These forecasting criteria define the formation and localization of the pegmatite belts and fields. The third group consists of criteria that emerge from the conditions for the formation and localization of pegmatite nodes and bundles. The fourth group are the criteria of pegmatite bodies that can be identified during study their internal structure. These are mineralogical-geochemical, structural-textural, petrochemical, thermobarochemical and thermoluminescent. Prospects for further work aimed at identifying new rare-metal and rare-earth metal deposits within pegmatite-bearing fields are estimated.

Abstrak

 

Perlindungan Terhadap Anak Yang Bekerja Membantu Orang Tuanya Sebagai Nelayan Menurut Hukum Internasional dan Implementasinya Di Indonesia

 

 

Indonesia sebagai Negara kepulauan dan salah satunya didukung oleh jumlah nelayan  menjadikan Indonesia sebagai egara kepulauan terbesar di dunia. Kondisi yang ada saat ini adalah kesejahteraan sosial yang memburuk di kalangan nelayan. Hal itu membuat tersendat-sendatnya pemenuhan kebutuhan pendidikan anak-anaknya merupakan salah satu faktor anak nelayan putus sekolah bekerja untuk membantu ekonomi keluarga.

 

Permasalahan yang timbul adalah Bagaimana perlindungan terhadap anak yang bekerja membantu orang tuanya sebagai nelayan menurut hukum internasional dan implementasinya di Indonesia.

 

Perlindungan terhadap anak yang bekerja membantu orang tuanya sebagai nelayan menurut Hukum Internasional diatur dalam Pasal 22 Deklarasi Hak Asasi Manusia Tahun 1948, Konvensi ILO No.138 yaitu batas umur dikatakan dewasa 15 tahun, dan dalam Pasal 28, Pasal 29, Pasal 31 (1) (2) dan Pasal 32 (1) Konvensi Hak Anak Tahun 1989. Sementara Implementasi Perlindungan terhadap anak yang bekerja membantu orang tuanya sebagai nelayan di Indonesia diatur dalam Undang-Undang Perlindungan Anak Pasal 9, Pasal 11 dan Pasal 59 yang menyatakan bahwa yang disebut sebagai anak adalah orang yang berusia di bawah 18 tahun dan atau belum menikah. Selain itu pula pemerintah dan lembaga negara yaitu Komisi Perlindungan Anak Indonesia (KPAI) yang memberikan perlindungan terhadap anak salah satunya adalah yang dikategorikan ke dalam bentuk buruh/ pekerja anak yaitu mancari ikan di lepas pantai seperti jermal. Yang dalam hal ini bisa disamakan dengan anak yang bekerja membantu orang tuanya sebagai nelayan.

THE USE OF TRANSLATION TOOL IN EFL LEARNING: DO MACHINE TRANSLATION GIVE POSITIVE IMPACT IN LANGUAGE LEARNING?
Authors: Mahardika Rizka
Published: December 2018

Translation tools are commonly used for translating a text written in one language (source language) into another language (target language). They are used to help translators in translating big numbers of translation works in effective time. There are three types of translation tools being studied in the article entitled Machine Translation Tools: Tools of the Translator’s Trade written by Peter Katsberg published in 2012. They are Fully Automated Machine Translation (or FAMT), Human Aided Machine Translation (or HAMT) and Machine Aided Human Translation (or MAHT). Katsberg analyzed how each translation tool works, the naturality and approriateness of its translation and the compatibility of using it. In this digital era, translation tools are not only popular among translators but also among EFL learners. Beginning with the use of portable dictionary such as Alfalink and expanding to the more sopisticated translation tool such as Google Translate. Some novice learners usually use this translation tools in doing their task without recorrecting the translation result. This happens perhaps because they do not have enough background knowledge to evaluate the translation result. Thus, it will be better when the learners have good mastery in basic English and train them to be aware in evaluating the result from translation tools. On the other words, Human Aided Machine Translation may be the wise choice to do translation task effectively and efficiently particularly in managing the time.
PENDIDIKAN SPIRITUAL DALAM KITAB TUHFAH AL-MAUDŪD BI AHKĀMI AL-MAULŪD KARYA IBNU QAYYIM AL-JAUZIYYAH
Authors: Hamzah Arief Rifkiawan
Published: December 2018

Tuhfah Al-Maudūd Bi Ahkāmi Al-Maulūd is one of the books of Ibn Qayyim Al-Jawziyyah which discusses different issues compared to other works. This article examines spiritual education written by Ibn Qayyim Al-Jawziyyah in his book. This study is interesting to do, since the focus of education mostly only penetrated the intellectual intelligence and emotional intelligence, while spiritual intelligence still has not received intense attention in education. Then the study of this book is still not much done in terms of spiritual education. This study is a literature study with the primary source of the book Tuhfah Al-Maudūd Bi Ahkāmi Al-Maulūd and other supporting books of Ibn Qayyim Al-Jawziyyah. The theory that the writer uses here is from Islamic education theory written by Syed Muhammad Naquib Al-Attas and Ramayulis, then about the sprititual intelligence of Ary Ginanjar Agustian and Danah Zohar-Ian Marshall. Based on the theory, Ibn Qayyim views that education is ta'dib, which represents the good of the body and the ruhaniyah. Spiritual intelligence is the first thing parents notice, from before birth until delivery. The educational environment should be designed to avoid bad images, noise, and action that could endanger the child's comfort.

EPISTEMOLOGI IRFANI (Sebuah Tinjauan Kajian Tafsir Sufistik)
Authors: Abshor Muhammad Ulil
Published: December 2018

Irfani Epistemology is one of reasoning system known in Islamic knowledge tradition, besides these are Baya>ni and Burha>ni. It is different with of baya>ni and burha>ni based on holy scripture and logic. Irfani is based on kasyf (Illuminative), overflowing knowledge by presence without through reason analytic. The way of reaching is the exercise of soul (hearth) through the steps of certain sprituality (maqamat) and the experince of certain devine inspiration (hal). ‘Irfani Epistemology in study of tafsir known by the Tafsir of sufistik, this consists of two tipologies or variaty of interpretation is tafsir of Nazari sufistik and Isyari sufsistik. Both these tipologies are to be discussed in this research, the first tafsir interpretes the teks of holy Qur’an by a mistical theory and the second of that is using a number of qalb means (inner meaning) because the Tafsir of sufistik explores the aspect of inner meaning in teks or scripture. Historically, the development of sufistik exegesis had expanded since the second century of Hijriyah to the present. The Tafsir of sufistik is by means of validity couldn’t be proved empirically, however the contex of sufistik (Irfan) is not based on external objection or logical sequence but it is by from itself, in fact the reality of self-consciousness in which is well-known in Sufistik (Inner experience) or Kasyf (Illuminative). Therefore it couldn’t be examined based on correspondent or coherent validity. Further the object is not only immaterial and essential characteristic, but also it is swa-objective (self-object-knowledge), so what the matter is known as objective is a characteristic of analysis and appeared in the act of recognizing itself.

The Dong Nai river is a source of supplying water for Ho Chi Minh city, Bien Hoa city and industrial areas. However, the status of the Dong Nai river has been seriously polluted which were caused by emission sources from urban areas, industrial zones, etc. In this study, the fuzzy comprehensive evaluation model (FCE) based on Entropy weight method was built to calculate pollution levels for 18 monitoring sites of the Dong Nai river with 7 parameters in the period 2005 – 2012. The results of study showed that the water quality of section 1 and section 2 are I level which mean good level. Section 3 is III ranking – medium pollution and section 4 is II ranking – slight pollution. Besides, the study also compared the results of the water quality between FCE and the water quality index (WQI). The results indicated that there isn’t difference between two methods. However, the FCE method is more practical, reasonable and acceptable. FCE was less affected by abnormal values than WQI.

Authors: Nguyen Phuoc Van , Vi Thun Chhoun , Pham Quan Thanh
Published: December 2018

Different technologies are currently available for biodiesel production from various kinds of lipid containing feedstock. Among them, the alkaline-catalyzed methods are the most widely studied. However, here are several disadvantages related to biodiesel production using alkaline catalysts such as generation of wastewater, catalyst deactivation, difficulty in the separation of biodiesel from catalyst and glycerin, etc. To limit the problems mentioned above, in this study, biodiesel is produced by a non-catalytic using C2H5OH. The effect of experimental variables (the molar ratio ethanol/oil of 41.18:1 – 46.82:1, reaction times of 50 - 90 minutes and reaction temperatures of 2750C - 2950C) on the yield of biodiesel was studied. The 96% yield of Cambodia biodiesel of reaction between C2H5OH and Jatropha Oil at 46:1 at temperature 2900C at 60 minutes no using catalysts. Obtained biodiesel fuel was up to the International Standard ASTM D6751 for biodiesel fuel blend stock (B100).

Published: December 2018

The SBMBMBR technology (sequencing batch moving bed membrane bioreactor), a combiantion of membrane filtration MF process in activated sludge with sequencing batch (SBR) moving bed using Anox Kaldnes K2 (MBBR), has been studied for the removal of organic and total nitrogen in tannery wastewater. After 170 days, reasearch results showed that the COD removal efficiency was ranged from 89,2±0,6 to 95,9±0,3% when the organic loading rate changed from 0,564±0,019 to 1.207±99 kgCOD/m3/day. The total nitrogen removal efficiency reached 30,0±4,9 to 65,9±13,3. The highest COD removal efficiency was 0,72±0,02 kgCOD/m3/day. The lowest nitrogen removal efficiency was 10,8±5,4% at 0,327±0,020 kgTN/m3/day of nitrogen loading rate. During the research, the adhensional tension of microorganism was insignificant. The biomass remained unchanged with 6.808±226 mg/L of Mixed liquor suspended solids (MLSS). When the salinity went up from 3.500 to 8.000 mgCl/l, the COD and nitrogen removal efficiency decreased. However, the conversion of nitrogen was improved and the recovery of biomass following the changed loading rate was quite fast.

Circulating tumor cells (CTCs) have been recognized as holding extraordinary potential for disease management in cancer patients including prognostic, therapy, and monitoring disease progression. Sensitive and quick detection of CTC could enable the approach to patients with early-stage and metastatic cancer. The technical challenge in this field consists of finding rare tumor cells (just a few CTCs in 1 ml of blood) and being able to distinguish them from epithelial non-tumor cells and leukocytes. The current methodologies have significant limitations such as low capture efficiency, cannot capture live cells and time consuming. This paper presents the development of a new generation of microfilter for size-based isolation of CTCs in epithelial cancer using silicon nitride membrane filters 0.5 cm by 0.5 cm square sheets with slit shaped pores of 5μm by 15μm. We evaluated the sensitivity and efficiency of CTCs capture in a model system using the MCF-7 cells (breast cancer cells) spiked in the blood from the healthy donors. Preliminary results this research shown that silicon nitride membrane filter is a very good candidate to be CTCs detection platfo.

One-dimensional (1-D) zinc oxide (ZnO) nanostructures, such as ZnO nanowires and nanorods, have in recent years attracted a lot of attention due to their many unique properties and possibility that can be applied to various nanoscale functional devices. In this study, ZnO nanowires have been successfully synthesized on Ti/glass substrates by an DC magnetron sputter deposition technique. Deposition of ZnO using this technique generally leads to the formation of ZnO thin film but not of nanowire. So prior to the ZnO deposition, a Cu labyer was prepared on the Ti/glass substrate using an electroless plating method under different conditions. X-ray diffraction (XRD) analysis confirmed that the ZnO nanowires with wurtzite structures have high crystal quality and are c-axis orientated. Scanning electron microscopy (SEM) showed the diameters of nanowires normally range from 60 to 150 nm and their lengths reach 20 μm. Photoluminescence (PL) measurements were adopted to analyze the optical properties of the nanowires. The existence of an electroless Cu layer is critical for the growth of the ZnO nanowires. In addition, the effect of the Cu deposition conditions on the diameters and lengths of the ZnO nanowires is discussed in details.

Published: December 2018

There are statistical downscaling methods such as: SDSM, LARS-WG, WGEN…, used to convert information on climate variables from the simulation results of General Circulation Model (GCM) to build climate change scenarios for local region. In this study, we used the LARS-WG model and HadCM3 GCM for two emission scenarios: B1 (low emission scenario) and A1B (medium emission scenario) to generate future scenarios for temperature and precipitation at meteorological stations and rain gauges in the Srepok watershed. The LARS-WG model was calibrated and validated against observed climate data for the period 1980-2009, and the calibrated LARS-WG was then used to generate future climate variables for the 2020s (2011-2030), 2055s (2046-2065), and 2090s (2080-2099). The climate change scenarios suggested that the climate in the study area will become warmer and drier in the future. The results obtained in this study could be useful for policy makers in planning climate change adaptation strategies for the study area.

Authors: Nguyen Hiep Van , Pham Thinh Van
Published: December 2018

Since the Second World War until now, every time when a large hole of power arises in the East Sea, China, by its force, is still seeking to illegally occupy the seas and the islands that do not belong to her. In the period of 1954 - 1975, America played a big role in international relations and America is also the direct invader encroaching Vietnam. The American war in Vietnam created many opportunities for China to obtain the right to control the Spratlys and Paracel Islands of Vietnam. America carried out her ambitions of encroachment and continuously caused disputes over the East Sea.

Livelihood strategies of the Mon-Khmer ethnic groups in Binh Phuoc province in the current development context of Vietnam
Authors: Ngo Lan Thi Phuong
Published: December 2018

The Mon-Khmer people are considered to be native in Binh Phuoc province of Vietnam. In the context of present development and integration, with specific socio-economic characteristics, these ethnic groups have experienced profound changes, especially in their livelihoods. These changes are associated with the lauching of the state’s socio-economic development policies, especially those, in recent years, relating to forest – the living environment of these groups. Livelihood changes are manifested in the nature of these ethnic groups’ traditional extensive cultivation, in their shifting of plants and in their participation in non-agricultural activities. By examining changing livelihoods of the Xtiêng, Mạ, and Mnong in Binh Phuoc province, this paper asserts that despite of having many policies which aim to upgrade socio-economic life of the underpriviledged in general and of these ethnic groups in particular, at the implementation stage of the policies, not much interest and attention has been paid to their abilities to adapt to the new settings and to their access to new opportunities.

Between April & May 2014, the Department of Archaeology (Faculty of History, University of Social Sciences and Humanities - Vietnam National University, Ho Chi Minh City) and the Department of Culture - Sports and Tourism of Ben Tre Province conducted an excavation of the compound tomb at Chợ Lách town (Chợ Lách district, Bến Tre Province). The main results are as follows: Archaeologists detected two raising architectures on brick ground like the architectural model of mausoleum, in which the big Mausoleum lies approximately directed southward, offset 3° east, including a stele house and a burial house in scale of 300cm in width, 240cm in length and 185- 205cm in height designed for 2-adult burial (normally a married couple often found in Nam Bộ Tombs). Two graves are of rectangular form because only soil walls surrounded the graves. They are submerged in water in the depth of 70-275cm, decomposed, containing just a piece of the adult skull, 5 very small bronze balls and plant traces (as coconut fiber and fruit (Mangrove palm), Bần rind (Sonneratia) and Ráng leaves (Acrosticlum aureum Linn), pottery and ceramic pieces etc. The small architectural mausoleum with stele and burial houses was opened heading straight West and with the scale of 140cm in length, 65cm in width and 95cm in height. The rectangular burial pit, with the dimension of length 130cm, width 60cm, depth 70cm, not flooded, so the wooden coffin covered by sarcophagus with iron nails is preserved. There are remains of a lying face-up child, spreading legs, wearing 2 bronze buttons. The baby was about 2-4 years old with the height of 100-110cm. From the results of forensic examination and comparative research into the tomb structure scale and the artifact collected from the excavated pit, the authors state that: The tomb monuments in Cho Lach belong to the styles of stele and burial house for aristocratic title, to the Nguyen Dynasty in two centuries 18th and 19th, with structure building material, brick grounds, steel frames, wooden coffins with iron nails, spherical virtual buttons, ceramic fragments etc. For the first time in Vietnam, tomb monuments contained such specific characteristics as 5 very small bronze balls and plant traces (as coconut fiber and fruit (Mangrove palm), Bần rind (Sonneratia) and Ráng leaves (Acrosticlum aureum Linn), pottery and ceramic pieces etc. Especially the first time in Vietnam, archaeologists find 2 aristocratic mausoleums sitting next to each other, perhaps belonging to the same family, in which the parents were lying in big burial pits and their child (ageing from 2 to 4 only) was lying in a small burial pit, but a majestic stele house of this model has still been built from the Medieval & Post-Medieval Ages.
