Published: December 2021

Semenjak penetapan status sebagai Pandemi global oleh badan kesehatan dunia (WHO), wabah Corona Virus Disease (Covid-19) sudah menjadi momok di seluruh penjuru dunia. Berbagai standar prosedur penaggulangan penularan telah ditetapkan oleh WHO untuk memutus mata rantai penularan. Pemerintah kabupaten Bone melalui surat edaran Sekretaris Daerah No. 800/1919/VI/BKPSDM/2020 tanggal 4 Juni 2020 perihal sistem kerja Pegawai Aparatur Sipil Negara (ASN) dalam tatanan normal baru, mengatur kehadiran pegawai menggunakan absensi secara manual dan tidak menggunakan mesin absensi sidik jari. Hal ini tentunya akan berpengaruh pada pencatatan kinerja tiap ASN, dimana data absensi sudah terhubung dengan aplikasi e-kinerja yang sudah diterapkan pada lingkup kabupaten Bone. Tujuan dari penelitian ini adalah pembuatan aplikasi absensi online berbasis mobile Android untuk menjadi alternatif cara absen dengan memanfaatkan web service menggunakan metode komunikasi data Representational State Transfer (Rest) serta memanfaatkan protocol HTTP menggunakan format JavaScript Object Notation (JSon) dan bahasa pemrograman Java sebagai bahasa pemrograman aplikasi berbasis mobile. Hasil dari penelitian ini berupa aplikasi absensi berbasis mobile yang telah dilakukan pengujian performa web service menggunakan Aplikasi Apache JMETER untuk memastikan aplikasi ini sudah siap digunakan secara bersamaan oleh banyak ASN.

Bụi phát sinh ở các mỏ than là nguyên nhân chính gây nên bệnh phổi và các vụ nổ bụi trong mỏ khai thác than. Nước được sử dụng để kiểm soát sự phát sinh bụi trong quá trình khai thác do đặc tính kỵ nước của bụi than, chính vì vậy, một chất hoạt động bề mặt được bổ sung để cải thiện khả năng làm ướt cũng như hiệu quả kiểm soát bụi. Do đó, lựa chọn chất hoạt động bề mặt (CHĐBM) là rất quan trọng. Nghiên cứu này đánh giá hiệu quả của 03 loại chất hoạt động bề mặt: tritonX-100 (non-ion), sodium lauryl sulfate (anion) và cetyl trimetyl amoni bromua (cation) đối với bụi than ở mỏ than Cẩm Phả - Quảng Ninh. Kết quả nghiên cứu chỉ ra rằng, khi bổ sung thêm các CHĐBM vào trong dung dịch thì cải thiện được giá trị sức căng bề mặt, mức độ thấm ướt và cải thiện hiệu quả xử lý bụi đối với bụi than và tritonX-100 (non-ion) hiệu quả cải thiện cao nhất.

Bài toán quan sát quỹ đạo đa mục tiêu (Multi-Target Tracking - MTT) có rất nhiều ứng dụng trong thực tiễn, đặc biệt là trong an ninh quốc phòng. Những kết quả nghiên cứu đã được công bố cho đến thời điểm hiện tại chủ yếu dùng phương pháp ước lượng tuần tự Bayes (Bayesian Sequential Estimation - BSE) để cập nhật trạng thái và xây dựng các thuật toán bám quỹ đạo của các mục tiêu. Các thuật toán đó đều là những thuật toán không tầm thường vì chúng được gắn với các mô hình ngẫu nhiên rất phức tạp. Hai vấn đề quan trọng nhất đối với MTT là: xác định số mục tiêu hiện có tại mỗi thời điểm và xác định quỹ đạo chuyển động của chúng.
Các thuật toán bám quỹ đạo đã được công bố gặp khó khăn trong việc xác định mục tiêu trong trường hợp mục tiêu mới xuất hiện ngay tại thời điểm quan sát hiện tại. Trong bài báo này, chúng tôi trình bày một kết quả nghiên cứu để giải quyết vấn đề xác định số mục tiêu trong MTT tại mọi thời điểm bất kỳ khắc phục được khó khăn nói trên với kỹ thuật sử dụng công cụ mô hình Markov ẩn (Hidden Markov Model - HMM). Kỹ thuật sử dụng công cụ HMMs trong việc giải bài toán MTT, trong các kết quả đã được công bố, chưa có công trình nào đề cập đến.

DEEP LEARNING TECHNIQUE - BASED DRONE DETECTION AND TRACKING
Authors: Truong Xuan Tung 
Published: December 2021

The usage of small drones/UAVs is becoming increasingly important in recent years. Consequently, there is a rising potential of small drones being misused for illegal activities such as terrorism, smuggling of drugs, etc. posing high-security risks. Hence, tracking and surveillance of drones are essential to prevent security breaches. This paper resolves the problem of detecting small drones in surveillance videos using deep learning algorithms. Single Shot Detector (SSD) object detection algorithm and MobileNet-v2 architecture as the backbone were used for our experiments. The pre-trained model was re-trained on custom drone synthetic dataset by using transfer learning’s fine-tune technique. The results of detecting drone in our experiments were around 90.8%. The combination of drone detection, Dlib correlation tracking algorithm and centroid tracking algorithm effectively detects and tracks the small drone in various complex environments as well as is able to handle multiple target appearances.

Authors: Le Minh Thuy 
Published: December 2021

In this paper, a simple power - based Direction of Arrival (DoA) sensor is investigated. This sensor is applied in direction finding systems working at 2.6 GHz. The proposed sensor can determine the DoA via a simple formula compared to the algorithms – based methods. The sensor structure consists of simple components: two receiving antennas and a power dividers which have a good isolation between output ports based on hybrid couplers (HCs). With the range of simulation DoA from 0o to 35o, the proposed sensor yields the error of less than 5o.
OPTIMIZATION OF PHYTOESTROGENS EXTRACTION FROM SOY GERM USING RESPONSE SURFACE METHODOLOGY
Authors: Le Minh Chau 
Published: December 2021

Phytoestrogens are phytochemicals with antioxidant activities and potential health benefits. Their contents in soy germ is the highest compared to that in parts of soy seed. Response surface methodology (RSM) using Box Behnken Design of four factors was employed to optimize the extraction conditions for phytoestrogens. The Box Behnken Design with five replicates at central point was applied. The four independent variables investigated in this experiment were extraction time (X1) 60-120 minutes, solvent/solid ratio (X2) 8-12, extraction pH (X3) 8-10, ethanol concentration (X4) 50-70%. The high coefficient values indicated that the variables were fitted to the regression for the total phytoestrogens (R2 = 0.9887). Optimum conditions for maximizing total crude phytoestrogen content were 90 minutes for the extraction time, 12/1 for the extraction ratio, 9 for the extraction pH, and 65% for the ethanol concentration.
Experimental Studies on Mechanical Properties of Carbon Nanotube Reinforced Aluminum 7075 Composite Material
Authors: Chidananda Swamy Mahendra Kumar , Venkatagiriyappa Raghavendra Bommanahalli 
Published: December 2021

In the present work multiwalled carbon nanotubes were added as reinforcement to aluminum 7075 matrix at 0.5%, 0.75% and 1.25% by weight proportion through stir casting technique. The mechanical properties of the produced composite were studied. The composite has considerably good tensile and wear resistance properties and hence finds its best suited application in aircraft frame and wings structures. Microstructure analysis through SEM showed a uniform distribution of the reinforcement material in the matrix. XRD graphs were taken at selected points during microscopic studies to determine the chemical composition of the matrix alloy, the reinforcement and the composite. The experimental results showed that 1.25% reinforcement in the composite material exhibited a tensile strength of 560 N/mm2 and a compression strength of 649.6 N/mm2 as the highest among the compositions. Thus, the reinforcement addition at 1.25% improved the tensile and compression strength of the composite material.
Socio-economic determinants of alcohol consumption for South Africa
Authors: Rashied Naiefa 
Published: December 2021

Aims: To examine the socio-economic factors associated with alcohol consumption in South Africa.
Design: Cross-sectional study exploring the various socio-economic factors associated with alcohol consumption in South Africa.
Setting: South Africans older than 15 years across the country’s nine provinces.
Participants: Adult respondents of the alcohol intensity and frequency questions in Wave 4 of the National Income Dynamics Study (NIDS) (n=28 401).
Measures: Alcohol, demographic, emotional, health and neighbourhood variables.
Findings: White and Mixed Heritage (referred to as ‘Coloured’ in South Africa) adults were more likely to consume alcohol, while Indian and White adults were less likely to binge drink relative to African adults. Males at greater risk of depression, and those who resided in neighbourhoods where frequent alcohol and drug abuse was common, were more likely to binge drink. Females who exercised more than three times a week were also more likely to drink and binge drink. Adults who smoked were more likely to drink and binge drink relative to non-smoking adults. Accounting for binge drinkers’ household size, average monthly household spending for binge drinkers was low, which suggests that binge drinkers under-reported household alcohol spending. There was evidence of drinking and binge drinking among pregnant women.
Conclusions: Binge drinking trends related to race, gender, neighbourhood, pregnancy and household alcohol spending warrant further investigation and consideration for possible future alcohol interventions in South Africa.
Bundahishn
Authors: Thrope Samuel 
Published: December 2021

Abstract

The
Bundahishn
, meaning primal or primordial creation, is the most important Zoroastrian text on creation, cosmology, and eschatology. Written in the Zoroastrian dialect of Middle Persian during the early Islamic period, the
Bundahishn
includes and interprets traditions going back to the Avesta as well as Sasanian and post‐Sasanian materials. The book is composed in a three‐part structure that mirrors the Zoroastrian division of time into creation, the period of the mixture of good and evil in the created world, and the final eschatological battle. An essential scholarly source for the study of ancient Iranian religion, philosophy, myth, history, and language, the
Bundahishn
is especially important in defining the central characters and categories of Zoroastrian theology, including the good creator god Ohrmazd and the Evil Spirit Ahriman, spiritual (
mēnōg
) and material (
gētīg
) existence, and the human role in the cosmos. In its scientific chapters on astronomy, medicine, zoology, botany, and others, the
Bundahishn
displays its dialogue with the intellectual environment of the early Islamic era.
Laozi
Authors: Zhou Boqun 
Published: December 2021

AbstractLaozi is the putative author of theLaoziand founder of philosophical Daoism in ancient China, although both identities have been called into serious question by critical scholarship. Ancient manuscripts found in the past few decades show that the received, canonical text of theLaoziis most likely an anthology of wisdom sayings accrued and edited over time. While it is impossible at the current time to pinpoint a date of initial formation, one can be certain, thanks to the discovery of the Guodian manuscripts, that at least a third of the textual contents in the receivedLaoziwere in circulation around 300bce. The receivedLaoziunderstands cosmic processes as the alternation of dyads such as day and night, hot and cold, and good and bad. Embedded in the constant reversal of opposites, human activity must be guided by an ironic principle that prescribes the opposite of what common sense requires. In contrast to the male type of action that is assertive, ambitious, and combatant, theLaoziadvocates the female type (known aswuweiandziran) that remains tranquil and yielding but ironically possesses real strength. The female type of action is ethically and practically better because it is less violent but more effective. It becomes the highest guiding principle in human life and government.
Numerology, China
Authors: Hon Tze‐Ki 
Published: December 2021

Abstract

Like other aspects in ancient Chinese thought, numerology was closely linked to cosmology, political legitimacy, and moral cultivation. Drawing from Confucianism and Daoism, ancient Chinese believed that the cosmos is an organismic process without beginning or end. They also believed that political authority and human morality are reflections of the constant unfolding of the universe. As representations of the great flow of the universe, numbers were symbols of the movement and interchanges of the yin and yang forces. They were also the building block upon which a code of behavior could be developed to maintain political stability and social harmony. Hence, in ancient China, numerology was imbued with political and social meanings. Its goal was not to develop an abstract logic based on numbers and equations; nor was it to promote a rational thinking founded on numerological symbols. Instead, it was to decipher “the mandate of heaven” (
tianming
) and to match the human world with the natural world. In this entry, I discuss the number system of the Han dynasty (206
bce
–220
ce
) that was based on the
Yijing
(Book of Changes).
Yin‐Yang and Five Agents
Authors: Sabattini Elisa Levi 
Published: December 2021

Abstract
This entry focuses on the early usages of the ideas of “yin‐yang” and the “five agents” in Chinese tradition. Social stability and ethical issues were connected to the natural order of the cosmos through the principles of “yin‐yang” and “five agents.” In time, from the imperial period on, these principles became part of the political rhetoric of ministers and thinkers.
Magic, China – Intellectual History
Authors: Kory Stephan N. 
Published: December 2021

AbstractToday, magic is often distinguished from science as its ancestor and as an infallible and untestable activity (i.e., failed science). It is also often distinguished from religion as an immediate ancestor of it and as an attempt to control spiritual power for immediate personal ends rather than an attempt to access or avoid this power for protracted communal ends. Magic is also frequently approached as a heterodox activity reliant on occult knowledge rather than an orthodox activity reliant on canonical knowledge. Attempts to control spiritual power for specific and immediate ends are well attested in ancient China, but most are sanctioned attempts described from the perspective of the royal or imperial state. While descriptions of unsanctioned or deviant attempts are not well documented until the late Zhou, they rapidly increase through subsequent periods and the development of new canon‐based religious traditions like Daoism and Chinese Buddhism at the end of and after the Eastern Han gave rise to a plethora of new institutional religious perspectives on licit and illicit attempts to control spiritual (including demonic) power.
Spring and Autumn Annals
Authors: Tashima Pauli K. 
Published: December 2021

Abstract

The
Spring and Autumn Annals
(
Chunqiu
春秋, hereafter the
Annals
) is a historical chronicle that represents one of two major ancient Chinese traditions of historiography: one presents information in the form of the official annals; the other, in the form of narrative or exposition. Belonging to the former tradition, the
Annals
records mainly political events that occurred from 722 to 479
bce
. Despite or perhaps because of the extremely compressed style of language used in the
Annals
, written exegesis has been generated since the formation of the text to explicate the significance of the restricted word choices employed. Associated with the
Annals
, three major exegetical traditions have survived today as written texts, the
Zuo Tradition
左傳 (compiled ca. fourth century
bce
),
Gongyang Tradition
公羊傳 (compiled ca. fourth–second century
bce
), and
Guliang Tradition
穀梁傳 (compiled ca. third–first century
bce
). All of these traditions approach the
Annals
with the assumption that certain implicit scribal rules governed the original composition of the text, norms that determined the types of information, honorific titles, vocabulary, and even word order that ought to be employed by the scribe making the records. But whereas the direct commentary in the
Zuo Tradition
focuses on explicating these rules in terms of ritual, rank, and hierarchy, the
Gongyang
and
Guliang
traditions ascribe weighty moral judgments to terminology in the
Annals
that appear to exegetes to have departed from the expected scribal rules.
Burning of the Books
Authors: Foster Christopher J. 
Published: December 2021

Abstract

The phrase “burning of the books” refers to a policy adopted by the First Emperor of Qin in 213
bce
that proscribed certain texts deemed politically threatening to the Qin dynasty. This policy was based on a proposal by Chancellor Li Si, which argued for the destruction of the “
shi”
(odes)
,
“
shu”
(documents), and “
baijia zhi yu”
(sayings of the hundred persons) in private collections, along with all non‐Qin historical records. This event – often mentioned alongside the “burying of the scholars” – has played a central role in Chinese historiography, and particularly in Confucian apologetics. Modern scholarship, however, has critiqued traditional portrayals of the Qin biblioclasm and its impact.
Mandate of Heaven
Authors: Grundmann Joern P. 
Published: December 2021

AbstractThe Mandate of Heaven (tianming天命) is perhaps the most prominent feature in early Chinese intellectual history. Initially associated with a rhetorical claim to legitimize the Zhou conquest over the Shang, the idea soon developed into a moral theory of history, retrospectively explaining the in part mythological change of ruling houses from Xia, Shang to Zhou in terms of a shift of Heaven's Mandate, caused by ritual excess and moral failures in those who lost it and by moral excellence paired with ritual restraint in those who were about to receive it. Moreover, with its pronounced decoupling of the notion of a high god from the exclusive, quasi‐genealogical access of one particular ruling lineage and its ancestral spirits, the idea of a universal, incorruptible theopolitical mandate heralded the distinction between transcendence and world‐immanence in early Chinese thought. Whereas the concept was combined with ideas of cosmic cycles, heavenly decreed fate, and even human nature in subsequent centuries after the end of the Western Zhou period, the originally moral notion of the Heavenly Mandate continued to constitute the chief ideological context for the legitimation of dynastic change and royal authority throughout pre‐imperial and imperial times.
Xin
(Heart‐Mind)
Authors: Grundmann Joern P. 
Published: December 2021

Abstract

In the early Chinese system of ideas, the organ of the heart (
xin
) was associated with human sentiments, intentions, and dispositions, but also with cognitive and evaluative activities, hence the alternative English rendering as “heart‐mind.” Judging from extant epigraphic sources, the heart was initially regarded as the seat of personal loyalty and political responsibility in the context of political bonds forged between the Zhou king and his vassals at the beginning of the first millennium
bce
. In this particular function it remained a crucial factor throughout the period of interstate and interlineage covenants after 771
bce
. With the decline of the covenant‐based aristocratic society around 450
bce
, the heart began to play a major role again in the development of Confucian moral and political philosophy. Ruist models of sociopolitical order worked on the premise that the evaluative and controlling functions of the heart potentially enabled each person to become an accountable social being. The parameters of well‐ordered social coexistence, it was believed, were either rooted in, or could be conceived with and approved of by, the heart. On the contrary, the early Daoist tradition advocated a decoupling of the heart from the realm of sociopolitical order and moral evaluative activity, which it regarded as ephemeral and obstructive for humans to arrive at a stage where they could discover the true Way (
dao
) within themselves and comprehend their place, not only in human society, but in the cosmos as a whole.
Organic Synaptic Diodes Based on Polymeric Mixed Ionic‐Electronic Conductors

Published: December 2021

AbstractNeuromorphic devices are likely to be the next evolution of computing, allowing to implement machine learning within hardware components. In biological neural systems, learning and signal processing are achieved by communication between neurons through time‐dependent ion flux in the synapses. Integrating such ion‐mediated operating principles in neuromorphic devices can deliver an energy efficient and powerful technology. Here a device known as a light‐emitting electrochemical cell is revisited and modified, exploiting its ability to modulate current through ion accumulation/depletion at the electrodes and turn it into an organic synaptic diode. This two‐terminal device is based on an organic mixed ionic‐electronic conducting polymer that serves as active layer for conduction of lithium ions as well as charge carriers. The ionic conduction properties are modified by cryptand molecules, able to reversibly capture ions. The device can be reliably switched between states for at least 100 cycles and displays state retention for multiple minutes. The applicability for neuromorphic applications is further demonstrated by exploring frequency‐dependent plasticity and paired‐pulse facilitation behavior in the millisecond range. The polymeric nature, combined with the simple two‐terminal architecture of the presented neuromorphic device, opens up a range of possibilities regarding the fabrication of artificial neural networks.
