Authors: Lumbantoruan Soraya Irene , Persadanta Pintanugra , Adrian Willy
Published: November 2023

The airport feasibility study is crucial for new airport proposals, serving as a prerequisite for determining the airport location. A key aspect of this study is assessing the construction's technical feasibility, particularly analyzing the topography of the proposed site. Topographic evaluation necessitates a terrestrial survey, known for its high precision as it's conducted directly on-site. However, this method is resource-intensive in terms of time, energy, and finances. Alternatively, DEMNAS and ASTER GDEM offer a cost-effective approach, providing comparable data with 8-meter and 30-meter spatial resolution, respectively. Analyzing their data against terrestrial surveys for a new airport site in Mahakam Ulu Regency, DEMNAS demonstrated an average elevation difference of 2.04 meters, whereas ASTER GDEM showed 8.89 meters. Validity and accuracy tests indicated that DEMNAS outperformed ASTER GDEM, showcasing a superior R2 value of 0.963 compared to 0.674, and lower RMSE of 2.417 meters versus 6.244 meters. The results suggest that DEMNAS, with its accuracy and efficiency, is a viable alternative for assessing the topographic conditions of potential airport sites, aiding in the preparation of comprehensive airport feasibility studies.
The Germanic Hero Wade and Wat's Dyke, Wales
Authors: Breeze Andrew
Published: November 2023

Wat's Dyke is an earthwork running along the border of England and Wales, like its western neighbour Offa's Dyke. But it is the shorter of the two, stretching a mere thirty-eight miles (62 kilometres) from the coast of the Dee Estuary to the environs of Old Oswestry, an Iron Age fortress in Shropshire, England. Although Wat's Dyke is now dated to the early ninth century (some decades later than Offa's Dyke), its name has remained obscure. A solution is yet possible. It can be related to the legendary Germanic hero Wade, who figures in Old and Middle English verse (including that of Chaucer), Old Norse, Middle High German, and even (as 'Wat') medieval Welsh. Wat's Dyke thus has unexpected links with poetry in Wales and beyond. There is another surprise: for Wade will be the mysterious warrior appearing on Maen Achwyfan, a tenth-century cross near Whitford, a Welsh village neighbouring the Dyke. The arguments for all this can be set out in four parts. We start with accounts of Wat's Dyke; move on to Chaucer and others on Wade; discuss the 'Wat' praised by Welsh bards; and end with Wade as the hero of both Maen Achwyfan and a lost monument to the west of it at Meliden (near Prestatyn) recorded by Edward Lhuyd (1660-1709), pioneer Oxford archaeologist. Plenty to say, then, on the past (Celtic, Anglo-Saxon, Scandinavian) of this region, where north-east Wales borders the English counties of Cheshire and Shropshire.

Published: November 2023

The advent of rapid digital technology has opened doors to a new domain for criminal activities, commonly termed as computer crimes. Stringent penalties have been instituted by various countries and institutions to combat these offenses executed through computers or networks. Central to investigating these crimes is digital evidence, pivotal in the realm of digital forensics. The digital forensics process comprises five critical phases: acquisition, preservation, analysis, reconstruction, and presentation. Its core aim is to locate and present digital evidence in court, aiding in determining the culpability of individuals involved in computer crimes. This discipline encompasses specialized fields such as data recovery, conversion, erasure, file identification, encryption, decryption, and IP address tracing to apprehend culprits. This paper conducts a thorough examination of the digital forensics stages using sample cases that elucidate five distinct computer crimes. It delves into evidence origins, collection methods, and preservation techniques utilized in the investigation. Once this meticulous process is completed, the digital forensics team compiles documented findings for presentation in a court of law.
A novel coherence optimization algorithm for forest height inversion using single-baseline PolInSAR images
Authors: Thieu Huu Cuong , Pham Minh Assoc.Prof.Dr Nghia , Phan Huy Anh
Published: November 2023

Forest height is one of the influential information for the management of forest cover and is also one of the criteria to evaluate the growth of organisms in the forest ecosystem. This paper suggests a novel coherence optimization algorithm to increase the accuracy of forest height estimation using the L-band PolInSAR images. First, the ground phase and coherence line are determined based on the mean of the coherence set. Then, the proposed algorithm is developed by adding more forced conditions to determine the volume-only coefficient coherence optimization. Finally, the forest height and extinction coefficient can be extracted by comparing the volume-only optimal coherence coefficient with the values in the look-up table. The effectiveness of the proposed method was evaluated with PolInSAR simulated and spaceborne data. Experimental results show that the proposed method has improved the accuracy of estimated forest height by more than 0.9m compared with the forest height retrieval algorithm by Tayebe.
Design of equalizers for frequency selective MIMO systems with low redundancy
Authors: Ta Chi Hieu
Published: November 2023

In this paper, we propose several designs of filter bank based decision feedback equalizers (DFE) for frequency selective multi-input multi-output (MIMO) systems. Transmission schemes over frequency selective channels are typically block based, and redundancy in form of guard intervals must be used to avoid inter-block interference (IBI). This paper will focus on the case where spectral efficiency demands low levels of redundancy. Then the remaining IBI will be eliminated by a separate feedback loop. The co-channel interference (CCI) inherited in MIMO channels will be eliminated by different DFE schemes. In another approach, a multi-tap MIMO DFE will be designed to deal with both IBI and CCI. The simulation results show that for quasi-static frequency selective MIMO channels, the multi-tap DFE provides the best performance while for Raleigh frequency selective MIMO channels, the dual loop DFE is a good solution for transmission with low redundancy.

Authors: Xiao Lin , Zeng Jianping
Published: November 2023

Strategic competence, as a meta-cognitive ability, determines the other translation sub-competences. To tease out how students’ strategic competence is developed in translation project is significant in enlightening the translation teaching practice. This study explores how five Chinese college students’ translation competence, particularly their strategic competence, develop within a translation project introduced into the translation teaching of the authors’ institute. Strategic competence includes four parts: problem identification, solution proposal, action taking, and decision making. By examining both the translation process and the translation product, including translation tasks, translation logs, group discussions, and interviews from five student translators, we found that the overall translation competence of the student translators has significantly improved. The development of various elements of strategic ability is uneven, with the abilities to identify problems, evaluate issues, and take measures showing the most significant improvement. However, there is a lag in decision-making capabilities in translation output. Based on these findings, the study provides concrete suggestions for improving the teaching of translation.

God created humans in pairs of their own kind to continue their offspring through legal marriage. In practice, marriages are not carried out in accordance with applicable regulations and are recognized by the state. There are still many people who carry out unregistered marriages which have both legal, social and psychological consequences. The purpose of this paper is to determine the understanding and knowledge of the legitimacy and legal consequences of unregistered marriages in the Uswatum Khasanah study group about unregistered marriages. The results showed that before the counseling was carried out they had the same perception about unregistered marriage and registered marriage because the point was to avoid adultery, after counseling they knew and understood the weaknesses of unregistered marriage, especially regarding the position of women and their offspring. This means that people do not understand the status of unregistered marriages, so intensive counseling is needed regarding unregistered marriages to community groups, especially those who are vulnerable to conducting unregistered marriages

THE RESPONSES OF HUMAN PERIODONTAL LIGAMENT CELLS TO EXOGENOUS INTERLEUKIN-12
Authors:   , Ayuthaya Benjar
Published: November 2023

Presence of cytokines during periodontal inflammation has been proposed as a key factor to modulate homeostasis of periodontal tissue. Interleukin 12 (IL-12) is one of the cytokines, which its expression was found to be increased associated with the severity of periodontal destruction. However, the exact role of IL-12 in periodontitis is still unclear. As human periodontal ligament (hPDL) cells are major local cells that have an ability to respond to many immunological stimuli, this study aimed to investigate the responses of hPDL cells to exogenous IL-12 for determining the osteoimmunological and immunomodulatory effects of IL-12 on hPDL cells. HPDL cells were incubated with IL-12 in a dose and time dependent manner. The expression levels of RANKL, OPG, IFNγ, IDO, HLA-G, as well as stem cell markers were evaluated by quantitative PCR. The protein levels of RANKL, IFNγ, HLA-G and the activity of IDO were measured by ELISA, flow cytometry and enzymatic activity assay, respectively. Chemical inhibitors or neutralizing antibody were used to elucidate underlying pathways. The results of this study showed that, under the influence of IL-12, hPDL cells expressed significantly higher levels of RANKL. This induction occurred indirectly by the activation of intermediate molecule(s). Addition of suramin and EGTA suggest that the nature of the involved intermediate molecule(s) was possibly the ligand that could activate heterodimeric G protein signaling in a calcium dependent pathway. In addition, IL-12 also induced the expression of the immunosuppressive proteins: IDO and HLA-G in hPDL cells via an IFNγ dependent pathway. Moreover, the expression of the stem cells markers was also upregulated in IL-12-treated hPDL cells. Together, these data indicate both pro- and anti-inflammatory effect of IL-12 by inducing expression of RANKL and immunomodulatory properties of hPDL cells. These provide the role of IL-12 in regulating homeostasis of periodontal tissue.
BASIC FIBROBLAST GROWTH FACTOR REGULATES THE DIFFERENTIATION ABILITY OF STEM CELLS ISOLATED FROM HUMAN EXFOLIATED DECIDUOUS TEETH
Authors:   , Nowwarote Nunthawan
Published: November 2023

The basic fibroblast growth factor (bFGF) play a crucial role in various biological processes, including cell growth, survivor, migration and differentiation in several types of stem cells. In this dissertation was focusing particularly on stem cells from human exfoliated deciduous teeth (SHEDs). SHEDs exhibited fibroblast-like morphology and express mesenchymal stem cell surface markers. These cells were able to differentiate into various lineages, including osteogenic, adipogenic, and neurogenic lineages. First, the roles of bFGF in dental tissue-derived mesenchymal stem cells were reviewed. The evidences suggest that bFGF regulate stem cell behaviors may depend on several factors, including dose, exposure time and cells type. Second, roles of endogenous bFGF on cell proliferation and osteogenic differentiation were revealed. bFGF knockdown and chemical inhibition of fibroblast growth factor receptor led to the reduction of colony forming unit and the increase of osteogenic differentiation potency. Third, the effect of bFGF on stemness maintenance in SHEDs was examined. bFGF promoted a pluripotent marker, REX1, gene expression in SHEDs. The bFGF-induced REX1 expression was occurred via FGFR and Akt signaling pathway. In addition, the results demonstrated the participation of interleukin-6 in bFGF-induced REX1 expression. Together, these evidences support the influence of bFGF in the maintaining of stemness and controlling of differentiation ability toward osteogenic lineage in SHEDs.
Selective oxidation of saturated hydrocarbons catalyzed by oxovanadium(iv) complexes
Authors:   , Pongpipatt Paweena
Published: November 2023

The development of the selective oxidation of saturated hydrocarbons catalyzed by oxovanadium(IV) complexes was disclosed. Two types of ligands including Schiff’s base and picolinic acid could be prepared. The well-characterized oxovanadium(IV) complexes were applied under two diverse oxidizing agents: O2 and peroxide. The oxidation catalyzed by oxovanadium(IV) Schiff’s base complexes in zinc-pyridine-acetic acid system under O2 was thoroughly investigated for the effects of nine Schiff’s base complexes, amount and type of zinc, acid and solvent. VO(salophen) exhibited good activity in terms of yield of desired product(s) and selectivity. Utilizing this catalyst in combination with TBHP at reflux or H2O2 at room temperature in CH3CN could promote the selective oxidation reaction. These three catalytic systems revealed the unique characteristics for ketone formation as a major product together with small amount of accompanying alcohol. Employing VO(pic)2 in TBHP system, saturated hydrocarbons were oxidized faster than using VO(salophen) and still provided ketone as predominant product in good yield. The addition of hexabromoacetone (HBA) converted the activation process to furnish alkyl bromide efficiently instead of oxidized products. Chemoselectivity study implied the clues that reaction mechanisms of two systems were different. Non-radical pathway was operated in zinc-pyridine-acetic acid-O2 system while for peroxide system, the oxidation proceeded via radical process.

Graft copolymerization of 2,2,2–trifluoroethyl methacrylate (3FMA) onto natural rubber (NR) was synthesized in an emulsion system by using potassium persulfate (K2SO4) as an initiator. Since the polarity of NR and 3FMA monomer was different, the 3FMA monomer could not be directly grafted onto the NR structure. Thus, butyl acrylate (BA) was selected as a co-monomer to enhance the grafting efficiency (GE) of this system. The chemical structure of NR before and after graft copolymerization was detected by using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and nuclear magnetic resonance spectroscopy. The effects of initiator concentration, BA/3FMA wt ratio, reaction temperature and reaction time on monomer conversion, grafting properties and GE of the graft NR (GNR) were investigated. The maximum content of NR-g-poly(BA-co-3FMA) at 72.8 wt% was obtained by using 30/70 (w/w) BA/3FMA and 1.5 phr K2SO4 at 60 °C for 8 h. This condition provided GNR with 25.3 mol% grafted 3FMA content and 68.5% GE. The latex of the graft product exhibited the core-shell morphology. The thermal properties, mechanical properties, contact angle and surface energy were analyzed to evaluate the effect of the addition of graft product on the compatibility between NR and poly(BA-co-3FMA) phases in the NR/poly(BA-co-3FMA) films (20/80 (w/w)). The results revealed that the addition of 10 wt% GNR enhanced the compatibility of the polymeric constituents in the films resulting the improved hydrophobicity with high contact angle (109°) and higher toughness. Moreover, the oil swelling resistance of obtained film was higher than that of the commercial self-sealing film using in the laboratory, Parafilm MR.

The incompatibility and phase separation of fluorinated acrylate polymer/natural rubber (NR) blend was obtained due to polarity mismatch of polymeric constituents in the blend. To decrease the phase separation in the composite, the graft copolymerization was a favorite method to enhance the compatibility of the blends. In this study, 2,2,2-trifluoroethyl methacrylate (TFEMA) was grafted onto NR backbone, which was assisted by methyl methacrylate (MMA) acting as a co-monomer for enhancing the grafting efficiency (GE). The graft copolymerization was carried out by emulsion-grafting process via free radical using potassium persulphate (KPS) as an initiator. The grafting properties were investigated as a functions of initiator concentration, MMA/TFEMA wt ratio, reaction temperature and reaction time. Under the optimum conditions (condition: 50/50 (w/w) of MMA/TFEMA, 0.75 phr of KPS at 60 °C for 4 h) the obtained gross graft NR (GNR) contained the maximum %GE and grafted TFEMA content as 23.6% and 7.3 mol%, respectively, with 3.8% gel content. The chemical structure of GNR after soxhlet extraction was analyzed by using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and nuclear magnetic resonance spectroscopy (NMR). The morphology of GNR latex characterized by using transmission electron microscopy (TEM) was core-shell type. The graft product was then blended with PTFEMA to form modified PTFEMA films. The compatibility testing between polymeric constituents in the films was observed via Molau test and atomic force microscope (AFM). Water and hexadecane contact angles, surface energy and analysis of mechanical and thermal properties of the obtained films were also examined. It was observed that the addition of GNR provided the better surface and mechanical properties of the modified PTFEMA films than that of non-grafted NR.

Authors: Minasyan A. A.
Published: November 2023

The analysis of the early medieval written sources proves that on adopting Christianity as the state religion certain changes as to the perception of responsibility of the Motherland’s armed protection took place in the national consciousness. If previously that responsibility had been viewed at as undaunted and selfless protection of the native country’s borders, royal power, as well as countrymen’s safety, then now the duty of protecting the Christian creed, spiritual and material values of the Armenian Apostolic Church and its priests’ lives added to it. Notably, the provisions of the Christian creed regarding the transnational universal values, detached from ethnic belonging of a Christian, the love for enemies, the forgiveness and nonviolent resistance collide with the necessity to defend the Motherland with arms.
The attempt of reconciling those two diametrically opposite theses required implementation of significant theoretical and practical skillfulness on the secular and clerical leaders’ part. However, they succeeded in solving this problem through including the institutions of the Christian religion into the notion of the Motherland. Now the Motherland defendersfought not only for the independence of their country, but also
to protect the creed, for the preservation of spiritual and material values of the Armenian Apostolic Church and its churchmen. Moreover, in the particularly difficult conditions the churchmen themselves fought with arms in hands side by side with warriors and militia.

Professional contact with the dangerous and deleterious factors of activity inevitably affects people’s health. To name a few, the sanitary and hygienic conditions of the working environment, a lot of psychotraumatic factors of professional activity and way of life. The working environment can also directly affect the human brain, thereby increasing or decreasing his performance efficiency. Said factors can well influence on one’s psyche, and in particular cause anxiety.
In terms of the working environment affecting on a person’s health, and especially on its mental component, the military personnel whose service takes place in conditions of increased stress, in particular from that of the Air Defense Forces, who, throughout their professional activities, daily encounter many anxiety-provoking factors. These factors
take hold of their overall health and life quality, and deserve special attention. The electromagnetic radiation of ultrahigh frequency of nonthermal exposure is one of them to name.
Based upon the data received in the course of the research conducted by the authors in the units of the Air Defense troops of the RA Armed Forces, the liaison between the
quality of life and the anxiety level of said contingent has been analyzed. The analysis via Pearson's linear correlation coefficient made it possible to clearly identify the following
patterns: both state anxiety and trait anxiety do have a pronounced effect on the psycho-emotional and physical components of the quality of life of the military personnel of the Air Defense troops of the RA Armed Forces. Meanwhile their influence on the physical component of health is much less evident.
As claimed by the generalization and evaluation of the results of the research data analysis, specific recommendations have been worked out for the development and implementation of measures targeted at reducing the anxiety and improving the quality of life of this contingent of military personnel.
Հրետանային զորամասի անձնակազմի համալրվածության աստիճանի ազդեցությունը դրա մարտական գործողությունների արդյունավետության վրա / The influence of the Extent of Artillery Unit manning levels on the efficiency of its Combat actions

Published: November 2023

The extent of manning levels of artillery units (subsystem elements) has a direct influence on the efficiency of their employment. Consequently, one of the ways to increase the effectiveness of combat actions of an artillery regiment (AR) in case of its being undermanned is the appropriate distribution of available personnel among its sub-units. In this regard, a task arises to determine the minimum critical strength of
personnel subsystem elements of reconnaissance, control, fire and support for ensuring the maximum possible implementation of their combat capabilities.
An approach to solving this task is proposed, based on assessing the extent to which the AR realizes its combat capabilities, and calculations are made to determine the most optimal options for distributing available personnel among the specified sub-units of the AR.
Based on the results of the research and calculations carried out by the author, it was concluded that the minimum acceptable level of manning for the bodies belonging to the AR hierarchies is 80 %, and for divisions and batteries – 40-45 %. It follows from this that, in case of the AR being undermanned (casualties), it is incumbent on its commander to first of all ensure minimum manning at the regimental, and then at the
divisional and battery levels. In addition, it was ascertained that the AR is capable of successfully performing combat missions in the case when the manning of the elements of the reconnaissance subsystem is at the average regimental level, the control subsystem is 10-20 % above this level, and the fire subsystem is 5-10 % below this level, and it is appropriate to man the elements of the support subsystem to approximately 100 %.
