Innovation in Energy Security and Long-Term Energy Efficiency Ⅱ
The sustainable development of our planet depends on the use of energy. The increasing world population inevitably causes an increase in the demand for energy, which, on the one hand, threatens us with the potential to encounter a shortage of energy supply, and, on the other hand, causes the deterioration of the environment. Therefore, our task is to reduce this demand through different innovative solutions (i.e., both technological and social). Social marketing and economic policies can also play their role by affecting the behavior of households and companies and by causing behavioral change oriented to energy stewardship, with an overall switch to renewable energy resources. This reprint provides a platform for the exchange of a wide range of ideas, which, ultimately, would facilitate driving societies toward long-term energy efficiency
Cyberpsychology: The Understanding of Woman-Social Media's Interaction
The face can display how the emotion of a human. Some research concluded that it is possible to be different details of emotion and event. As found in the gender studies, men and women are having professional anger in both statuses for their own emotions. Especially for women who are actively become netizens of social media such as Facebook, Twitter, and Instagram are predictively more interactive in that media and have various emotions to say and receive anything from them. The critical introduction of social media from N. Bakić-Mirić explained a wide variety of topics including how to define the characteristics of new media; social and political uses of new media and new communications; new media technologies, politics, and globalization; everyday life and new media; theories of interactivity, simulation, the new media economy; cybernetics, cyberculture, the history of automata and artificial life. Therefore, more specifically, women have the psychology of becoming women in social media. Applying qualitative methodology, this study explores what cyberpsychology extend to women and how their emotion be on social media. The research contributes to women on to be careful with social media.

Epidemiological methods to evaluate the early impact of the COVID-19 pandemic.
The early phase of the COVID-19 pandemic represented a major challenge for health systems and local Governments, with no drugs or vaccines available to provide a pharmaceutical response. In the absence of formal reporting, data gaps and repression by authorities, real-time open-source data can be mined for risk assessment and response early on. In this thesis, open-source and survey generated data was synthesized in novel ways to develop new epidemiological insights into the COVID-19 pandemic and advise public health policy. There were also controversies in areas where no data on risks associated with cruise ship travel, healthcare workers, aged-care, and mass gatherings was available. This thesis analyzed a range of these issues in the first year of the pandemic.
In chapter 1, I summarized the literature on the COVID-19 pandemic and identified gaps in using open-source data for early responses to pandemics. In chapter 2, I assessed the impact of cruise ship travel on the transmission of COVID-19 both globally and in Australia. In chapter 3, in the absence of any reported data on healthcare workers, I estimated the burden of COVID-19 on Australian healthcare workers and the health system, by analyzing national healthcare worker infections and their occupational risk of COVID-19. Similarly, with no formal reporting on Australian COVID-19 aged-care infections and outbreaks, I estimated the burden of COVID-19 on Australian aged-care and aged-care workers in 2020, in chapter 4. With the controversy surrounding the May-June 2020, Black Lives Matter protests and COVID-19 associated risks, I estimated mask use and COVID-19 associated risks of these protests. In chapter 6, with the controversial mask mandates in Australia, I evaluated mask attitude and government and state sentiment during the COVID-19 pandemic in Sydney and Melbourne.
This thesis highlights the value of open-source, and survey data, which provides good insights into population attitudes around public health issues and practice and can enhance routine surveillance, early warning, and response. With many countries now minimizing COVID-19, the use of this data is even more important as prevention and control of the COVID-19 pandemic requires both long-term public health and epidemiology measures
Resonant transport in a highly conducting single molecular junction via metal-metal covalent bond
Achieving highly transmitting molecular junctions through resonant transport
at low bias is key to the next-generation low-power molecular devices.
Although, resonant transport in molecular junctions was observed by connecting
a molecule between the metal electrodes via chemical anchors by applying a high
source-drain bias (> 1V), the conductance was limited to < 0.1 G, G
being the quantum of conductance. Here, we report electronic transport
measurements by directly connecting a Ferrocene molecule between Au electrodes
at the ambient condition in a mechanically controllable break junction setup
(MCBJ), revealing a conductance peak at ~ 0.2 G in the conductance
histogram. A similar experiment was repeated for Ferrocene terminated with
amine (-NH2) and cyano (-CN) anchors, where conductance histograms exhibit an
extended low conductance feature including the sharp high conductance peak,
similar to pristine ferrocene. Statistical analysis of the data along with
density functional theory-based transport calculation suggests the possible
molecular conformation with a strong hybridization between the Au electrodes
and Fe atom of Ferrocene molecule is responsible for a near-perfect
transmission in the vicinity of the Fermi energy, leading to the resonant
transport at a small applied bias (< 0.5V). Moreover, calculations including
Van der Waals/dispersion corrections reveal a covalent like organometallic
bonding between Au and the central Fe atom of Ferrocene, having bond energies
of ~ 660 meV. Overall, our study not only demonstrates the realization of an
air-stable highly transmitting molecular junction, but also provides an
important insight about the nature of chemical bonding at the
metal/organo-metallic interface.Comment: 23 pages, 6 figures, supplementary include
A consensus protocol for the recovery of mercury methylation genes from metagenomes
Mercury (Hg) methylation genes (hgcAB) mediate the formation of the toxic methylmercury and have been identified from diverse environments, including freshwater and marine ecosystems, Arctic permafrost, forest and paddy soils, coal-ash amended sediments, chlor-alkali plants discharges and geothermal springs. Here we present the first attempt at a standardized protocol for the detection, identification and quantification of hgc genes from metagenomes. Our Hg-cycling microorganisms in aquatic and terrestrial ecosystems (Hg-MATE) database, a catalogue of hgc genes, provides the most accurate information to date on the taxonomic identity and functional/metabolic attributes of microorganisms responsible for Hg methylation in the environment. Furthermore, we introduce "marky-coco", a ready-to-use bioinformatic pipeline based on de novo single-metagenome assembly, for easy and accurate characterization of hgc genes from environmental samples. We compared the recovery of hgc genes from environmental metagenomes using the marky-coco pipeline with an approach based on coassembly of multiple metagenomes. Our data show similar efficiency in both approaches for most environments except those with high diversity (i.e., paddy soils) for which a coassembly approach was preferred. Finally, we discuss the definition of true hgc genes and methods to normalize hgc gene counts from metagenomes

Genomic Analysis of Antibiotics Resistance in Pathogens
The emergence of antibiotic-resistant pathogens currently represents a serious threat to public health and the economy. Due to antibiotic treatments in humans and veterinary medicine, prophylactic use and environmental contamination, bacteria are today more frequently exposed to unnatural doses of antibiotics and their selective effect.Antibiotic resistance can be encoded on chromosomes, plasmids, or other mobile genetic elements in bacteria. It may also result from mutations that lead to changes in the affinity of antibiotics for their targets or in the ability of antibiotics to act on bacterial growth or death. Exposure of bacteria, bacterial populations, and microbial communities to antibiotics at different concentrations shapes their genomic dynamics, as does the mobilisation and spread of resistance determinants. It is, therefore, essential to understand the dynamics and mobilisation of genes encoding antibiotic resistance, in human, animal, plant, and environmental microbiomes, through genomic and metagenomic approaches and bioinformatics analyses.This Special Issue gathers research publications on the horizontal transfer of antibiotic-resistance genes, their dissemination and epidemiology, their association with bacterial virulence, between bacterial genotypes and their phenotypes, and other related research topics
The psychologisation of natal astrology in the twentieth century
This thesis discusses the idea that natal astrology was psychologised in the twentieth century through an examination of ‘psychological astrology’. It is the first in-depth exploration of psychologisation in the English-speaking world through textual analysis of astrology books. It takes as a starting point the argument from Wouter Hanegraaff that magic survived the disenchantment of the world due to a process of psychologisation, which broadly means that magic has adapted along psychological
lines to become a different sort of magic to that previously found before the period characterised by disenchantment. The main reason for this adaptation is to acquire legitimisation from a subject, psychology, deemed to be scientific and acceptable in the modern world. The thesis asks whether the issues raised by Hanegraaff’s psychologisation thesis, and wider ideas on psychologisation, apply to the natal
astrology of the twentieth century, focusing on the form known as psychological astrology.
The question is tackled through textual analysis of the works of the three major astrologers identified by existing scholarship as having contributed to the twentieth
century development of psychological astrology: Alan Leo (1860-1917), Dane Rudhyar (1895-1985) and Liz Greene (1946- ). Significant consideration is also given to the major
psychological influence on Rudhyar and Greene: the psychologist Carl Gustav Jung (1875-1961).
Wider definitions of psychologisation considered include Christopher Plaisance’s extension of Hanegraaff’s work through his four-fold typology of psychologisation as
applying to esoteric discourse.
In exploring conceptions of psychologisation and modernity as presented within the works of the key psychological astrologers, the thesis demonstrates that the label of
psychologisation may be partly applied to psychological astrology. However, this form of astrology does not represent a fully adapted, disenchanted form seeking
legitimisation but is an adaptation for modern people for philosophical reasons and principally to maximise the use of astrology to enhance free-will and psychological
development. In doing so it can be characterised as more enchanted than disenchanted
Landscapes of Continued Deposition: A reinterpretation of the burial of Romano- British and Anglo-Saxon/Early Medieval lead tanks in Britain
Lead tanks from the Romano-British and Anglo-Saxon periods have become some of the most distinctive classes of artefact in Britain from those times. This thesis will be focussing on these artefacts at the time of the late fourth century to the late tenth century for evidence of continuity and change in depositional patterns between these periods.
Their findspots range from Cambridgeshire, Cumbria, Kent, Gloucestershire, Leicestershire, Lincolnshire, London, Norfolk, Nottinghamshire, Northamptonshire, Oxfordshire, Somerset, Su olk, Sussex and Yorkshire as well as examples in Scotland at Stidriggs and Whithorn in Dumfries and Galloway.
As of 2022, there is a total of 63 discovered from both periods at these locations across Britain. There are currently 38 from the Roman period and a further 25 of their later Anglo-Saxon counterparts. The main feature of this thesis will be the concept of landscapes of continued deposition. In this case, I searched for evidence of continued artefact deposition practices across both sets of discoveries regarding their state upon burial and the environment this occurred within. I assessed these alongside similar acts of deposition with Bronze and Iron Age cauldrons regarding choice in landscape, artefact buried and its state upon discovery to demonstrate evidence of landscapes of continued deposition. I also examined the abandonment of the tanks in their respective environments, comparing them with other patterns of artefact burial within these areas. I analysed them on a site to site basis as well as comparing evidence between sites. That created the opportunity to contextualise the burying of the tanks within broader depositional practices occurring in Roman and Anglo-Saxon Britain
Analysis, Design, and Implementation of a training center for variable-speed drive assembly production : Case ABB Oy
In manufacturing constant developments in production, processes, and layouts are required to respond towards increased production volume, quality, and customer requirements while meeting production targets and objectives. The case company of this thesis is ABB Ltd Drives Manufacturing Unit, which specializes in variable-speed drive production. ABB has recognized the need for re-designing a new and effective training center that supports One-piece flow assembly production since the old model is based on a cell production method. The training center is used for the training and integration of the company's new and experienced assemblers.
The aim of the research is to analyze the current training concept, design a new technical solution, and create a detailed implementation plan. Thus, the following research questions were developed: RQ1: How to develop and re-design a training center that supports the assembler for One-piece flow method production of variable-speed drives? RQ2: How to design and create the best possible layout and solution to guarantee safety, flexibility, ergonomics, clear flow, and the maximum utilization of space? RQ3: How to implement a training center that does not disrupt the main production lines and makes that way operations more efficient?
To achieve the objectives, the waste, bottlenecks, and issues of the current design were first identified by observing the training process and organizing focus groups and workshops with the production line and logistics (customer), and with the project team. Work-time studies were also conducted to solve the flow, outputs, cycle time, and waste time of the current process. These data collection methods aided in identifying potential improvement opportunities for the new design. The layout design process was committed by utilizing Lean principles and the Systematic layout planning procedure. AutoCAD was used to create and map various layout structures, options, and alternatives. The design process required the tendering of two layout location options, which were solved using the quantitative multiple attribute decision-making method, Weighted decision matrix (WDM), with voting based on the scoring of various criteria and features.
The result was a Flexible 6-phase U-model one-piece flow training center that allows assemblers to be trained in both one-piece flow and cell production methods. The new design's scope of work was delivered to the supplier, numerous negotiations were held to achieve the best final solution, and the new training center was ordered. In the end, a detailed implementation plan with an estimated schedule was created and a future action list was established. The new design fulfils the objectives and eliminates all issues, waste, and bottlenecks while also ensuring safety, ergonomics, flexibility, a clear flow, and a high-quality training process. With the new design, the efficiency, quality, and output of training and production operations will improve.Teollisuuden alalla tuotantojärjestelmiä, prosesseja ja layouteja on jatkuvasti kehitettävä sekä
modifioitava reagoidakseen kasvaneisiin tuotantomääriin sekä laatu- ja asiakasvaatimuksiin ja
saavuttaakseen asetetut tuotantotavoitteet ja päämäärät. Tämän opinnäytetyön toimeksiantaja
on ABB Oy Drives Manufacturing -yksikkö, joka on erikoistunut taajuusmuuttajatuotantoon. Toimeksiantaja on tunnistanut tarpeen uuden ja tehokkaamman koulutuslinjan suunnitteluun One-piece flow malliseen taajuusmuuttajien kokoonpanotuotantoon, sillä vanha tuotantomalli perustuu solutuotantomenetelmään. Koulutuslinjaa käytetään niin uusien kuten jo talossa olevien vanhojen kokoonpanoasentajien koulutukseen ja integrointiin.
Tutkimuksen tavoitteena on analysoida nykyinen koulutuskonsepti, suunnitella uusi tekninen
ratkaisu ja laatia yksityiskohtainen implementointisuunnitelma. Tavoitteiden saavuttamista varten on kehitetty seuraavat kolme tutkimuskysymystä: RQ1: Kuinka kehittää ja suunnitella koulutuslinja, joka tukee asentajia One-piece flow malliseen kokoonpanotuotantoon? RQ2: Miten suunnitella ja luoda paras mahdollinen layout ja ratkaisu, joka takaa turvallisuuden, joustavuuden, ergonomian, selkeän virtauksen ja maksimaalisen tilankäytön? RQ3: Kuinka implementoida koulutuslinja, joka ei häiritse päätuotantolinjoja ja tehostaa siten operaatioiden tehokkuutta?
Saavuttaakseen tavoitteet, nykyisen koulutuskonseptin aiheuttamat pullonkaulat, ongelmat ja
hukka tunnistettiin ensin havainnoimalla koulutusprosessia ja järjestämällä haastatteluja sekä
työpajoja tuotantolinjan ja logistiikan (asiakkaan) sekä projektiryhmän kanssa. Nykyisen prosessin virtauksen, ulostulon, tahti -ja hukka-ajan selvittämiseksi suoritettiin myös työaikatutkimuksia. Nämä tiedonkeruumenetelmät auttoivat kehitysmahdollisuuksien tunnistamisessa uutta ratkaisua varten. Layout suunnitteluprosessi toteutettiin Lean-periaatteita ja systemaattista layout suunnittelua käyttäen. AutoCAD layout suunnittelusovellusta käytettiin erilaisien asettelurakenteiden ja vaihtoehtojen luomiseen sekä kartoittamiseen. Suunnitteluprosessi edellytti kahden layout-sijaintivaihtoehdon kilpailuttamista. Lopputulos ratkaistiin äänestämällä kvantitatiivisen päätöksentekomatriisin (WDM) avulla, joka perustui eri kriteerien ja ominaisuuksien pisteytykseen. Tulokseksi saatiin joustava 6-vaiheinen U-mallinen One-piece flow koulutuslinja, jonka avulla asentajia voidaan kouluttaa sekä One-piece flow että solutuotantomallisesti. Uuden koulutuslinjan työn laajuus -dokumentti toimitettiin toimittajalle sekä lukuisia neuvotteluja käytiin parhaan loppuratkaisun saavuttamiseksi, jonka jälkeen uusi koulutuslinja tilattiin. Lopuksi koostettiin yksityiskohtainen implementointisuunnitelma arvioituineen aikatauluineen ja laadittiin toimenpidelista tulevaisuutta varten. Uusi ratkaisu täyttää asetetut tavoitteet ja eliminoi kaikki ongelmat, hukat ja pullonkaulat sekä takaa turvallisuuden, ergonomian, joustavuuden, selkeän virtauksen ja laadukkaan koulutusprosessin. Uuden ratkaisun myötä koulutuksen ja operaatioiden tehokkuus, laatu ja tuottavuus paranevat
