Analisis Relasi Fenomena Kriminalitas Dengan Kebijakan Publik
Authors: Iwansyah Henry
Published: January 2023

This study revealed the phenomenon of crime in North Lampung Regency, Lampung Province. The aim, in addition to getting a complete picture, is to analyze the relationship between empirical phenomena and local government policies. This type of research is "descriptive-analytic" using a qualitative approach. The techniques used are mostly based on in-depth interviews, documentation, observation and focus group discussion. The results of the study show that the crime rate in North Lampung Regency in the past 5 (five) years was quite alarming, although in the 2017-2018 range there was a significant downward trend.This decrease was caused by (1) District Government policies in the field of public security, which were implemented in the form of intensive government apparatus (police) in effort to eradicate crime, and (2) policies in the field of non-Public Security in the form of developing a creative economy and youth coaching. This study concludes that out of the 2 (two) types of policy, the handling of the public security sector is only effective in tackling crime for short-term needs. While for long-term needs, the District Government needs to develop a policy of economic development based on local potential.

Published: January 2023

There are many mathematical concepts found in music. Music is integrated into
Indian culture. It is a common practice among children in India to engage in music
lessons from a young age. The purpose of this study was to investigate the impact of
Indian music on the cognitive development of children to understand or reinforce
mathematics. Data was collected from three schools in Kolkata, India, through
interviews, observations, and survey questionnaires. Six different music classes from
three music schools were observed at different times. Observations were documented
through pictures, video recordings, running records, and anecdotal records. To
supplement these documentations, a field journal was kept at all times. The study was
qualitative in nature, and all data were analyzed thematically. The findings suggested
the importance of Indian music in children’s cognitive development and how Indian music
helped in learning mathematics. Both teachers and parents felt that music builds
concentration among children and also helps children with disabilities.

With present issues pertaining to discrimination and underrepresentation, the
growing demand towards equality and equity in society as reflected in legislative bills
being filed, street demonstrations, and organized programs, and the number of studies
that confirms higher productiveness of diverse workplaces, employers are expected to
evaluate prospective employees' socio-demographic profiles aside from knowledge, skills,
and personality. This has led to this study that aims to develop a conclusion if the
workplace in the tourism industry, resort establishments in Calamba City, Laguna,
embraces diversity, as well as to know the challenges that employees experience in
working with colleagues who have different demographic profiles, if any. Semi-structured
interviews were conducted with employees working in the front of the house of two
selected resorts, while data were analyzed using a quantitative and qualitative research
design, whereas frequency and percentage were computed, and thematic analysis was
performed. Results showed that firms still have their recruitment preferences or biases;
one firm prefers hiring older staff while the other prefers younger ones. The LGBT
community, on the other hand, has been found to be underrepresented. Moreover, the
assessed establishments also favor people with less experience and less formal
education, particularly for entry-level positions. Data presented also showed challenges
faced by employees working with their colleagues, particularly with the opposite gender,
those with lower and higher educational attainment, with different religion, and those
younger and older. Findings provide low organizational diversity, therefore, serve as an
indication of the need for programs that would promote inclusiveness in society. This
study explored a problem in the field of social science that seems to have been ignored
or least prioritized in the Philippines over the years. This study is a few of the
available literature that provides a picture of poor diversity in society, particularly
in workplaces that leads to operational dilemmas.

Presidential Threshold Ditinjau dari Undang-Undang Dasar Republik Indonesia Tahun 1945
Authors: Fernando Anggrek  , Hesti Armiwulan  , Didik Widitrismiharto
Published: January 2023

Abstract— Presidential Threshold provisions which are used as additional requirements for political parties to be able to carry pairs of candidates for President and Vice President in a general election. Political parties by the 1945 Constitution of the Republic of Indonesia are given the right to be able to independently or join other political parties (political party coalitions) to be able to nominate pairs of candidates for President and Vice President. Normatively, political parties are given rights by the constitution but since the enactment of the Presidential Threshold provisions, the constitutional rights of political parties cannot be fully implemented. With this provision, political parties may lose their rights as regulated in the constitution. This condition makes the Presidential Threshold provision contrary to the 1945 Constitution of the Republic of Indonesia.

Keywords: presidential threshold, political parties,general election.

Abstrak— Ketentuan Presidential Threshold yang dijadikan syarat tambahan bagi partai politik untuk dapat mengusung pasangan calon Presiden dan Wakil Presiden dalam sebuah pemilihan umum. Partai politik oleh UUD Negara RI 1945 diberikan hak untuk dapat secara mandiri atau bergabung dengan partai politik lain (koalisi partai politik) untuk dapat mengusung pasangan calon Presiden dan Wakil Presiden. Secara normatif, partai politik diberikan hak oleh konstitusi namun sejak berlakunya ketentuan mengenai Presidential Threshold, hak konstitusi partai politik tersebut tidak dapat dilaksanakan sepenuhnya. Dengan adanya ketentuan tersebut, partai politik dapat kehilangan haknya sebagaimana telah diatur dalam konstitusi. Kondisi tersebut membuat ketentuan Presidential Threshold bertentangan dengan UUD Negara RI 1945.

Published: January 2023

Uridine diphosphate glucuronosyltransferase-2B7 (UGT2B7), enzyme responsible for the elimination of a number of xenobiotics through glucuronidation, is expressed in the gut, kidneys, intestines, and brain. However, data on the frequency of UGT2B7 polymorphisms in the Croatian population are limited. The aim of this study was to assess the frequency of the UGT2B7 c.-161C>T (rs7668258) polymorphism in the Croatian population and to compare it with reported frequencies in other populations. This polymorphism is in complete linkage disequilibrium with the UGT2B7 c.802C>T (UGT2B7*2, rs7439366) variant, which is important in clinical medicine. The study reports data of 501 participants from University Hospital Centre Zagreb. All data were collected and analysed retrospectively. Genotyping was performed by real-time polymerase chain reaction (PCR) using the TaqMan® Drug Metabolism Genotyping Assay for UGT2B7 c.-161C>T (rs7668258). We found that 120 (23.95 %) participants were carriers of the UGT2B7 c.-161CC genotype and 255 (50.9 %) were heterozygous carriers (UGT2B7 c.-161CT), while 126 (25.15 %) were homozygous carriers of the variant allele (UGT2B7 c.-161TT). The frequency of the variant UGT2B7 c.-161C>T allele in this study was T=0.506. The frequency of the UGT2B7 c.-161C>T allelic variants and genotypes in the Croatian population is similar to other European populations.
Occupational exposure to silica dust in Slovenia is grossly underestimated
Authors: Margan Andrea , Verlak Dominika , Roj Gregor , Fikfak Metoda Dodič
Published: January 2023

As a by-product or material used in various industries crystalline silica contaminates the air many occupational settings. If its fine particles are inhaled, they are deposited in the lungs and may cause the development of silicosis, chronic obstructive pulmonary disease, and lung cancer. The goal of this study was to estimate occupational exposure to respirable crystalline silica (RCS) in Slovenia and the associated health risks. To do that, we ran two cross-sectional studies, one to determine the number of workers at risk of occupational exposure to RCS in Slovene industries and the other to determine and classify changes in the lung radiographs of glass factory workers exposed to RCS, as a means to infer health risks for other RCS exposed workers in Slovenia. However, the first study shows that official public data on occupational exposure to silica in Slovenia are unreliable and incomplete and that company representatives strongly underestimate occupational exposure to silica. Measurements of total and silica dust are made by 8.3 % and 1.8 % of companies working with silica, respectively. The second study shows that about a third of the exposed workers had lung changes associated with silicosis. We have failed to achieve the goal of our study, as the obtained data are grossly underestimated and unreliable, but it has opened our eyes as to what needs to be improved. All companies need to systematically be informed about occupational health risks, field inspections need to be consistent, regular, and intensified, and health surveillance of all exposed workers implemented regularly.
Cytotoxicity-related effects of imidazolium and chlorinated bispyridinium oximes in SH-SY5Y cells
Authors: Zandona Antonio , Zorbaz Tamara , Miš Katarina , Pirkmajer Sergej , Katalinić Maja
Published: January 2023

Current research has shown that several imidazolium and chlorinated bispyridinium oximes are cytotoxic and activate different mechanisms or types of cell death. To investigate this further, we analysed interactions between these oximes and acetylcholine receptors (AChRs) and how they affect several signalling pathways to find a relation between the observed toxicities and their effects on these specific targets. Chlorinated bispyridinium oximes caused time-dependent cytotoxicity by inhibiting the phosphorylation of STAT3 and AMPK without decreasing ATP and activated ERK1/2 and p38 MAPK signal cascades. Imidazolium oximes induced a time-independent and significant decrease in ATP and inhibition of the ERK1/2 signalling pathway along with phosphorylation of p38 MAPK, AMPK, and ACC. These pathways are usually triggered by a change in cellular energy status or by external signals, which suggests that oximes interact with some membrane receptors. Interestingly, in silico analysis also indicated that the highest probability of interaction for all of our oximes is with the family of G-coupled membrane receptors (GPCR). Furthermore, our experimental results showed that the tested oximes acted as acetylcholine antagonists for membrane AChRs. Even though oxime interactions with membrane receptors need further research and clarification, our findings suggest that these oximes make promising candidates for the development of specific therapies not only in the field of cholinesterase research but in other fields too, such as anticancer therapy via altering the Ca2+ flux involved in cancer progression.

Authors: Astuti Laily Widya , Huriah Titih
Published: January 2023

Objective: This study aimed to determine the effect of combined diaphragmatic breathing and therapeutic walking exercise on peak expiratory flow in asthma patients.

Methods: The research design used a quasi-experiment nonequivalent pretest and posttest design. The research sample contained 38 respondents divided into intervention and control groups, selected by simple random sampling. The control group received standard drug therapy, while the intervention group received standard drug therapy and a combination of diaphragmatic breathing and therapeutic walking exercise for 2 weeks. This exercise was carried out in the morning, 6 times a week, with 5 diaphragmatic breathing and exhalations per exercise. After that, a 1-min break was followed by a therapeutic walking exercise of 5–15 min, with an increased duration. Both groups measured the peak expiratory flow before and after the intervention using a peak flow meter. The data analysis used central tendency and t-test.

Results: The results showed that the mean peak expiratory flow in the intervention group was 306.84, while in the control group, it was 232.63, with the value of the t-test being −14.17 (P < 0.0001).

Conclusions: Diaphragmatic breathing and therapeutic walking exercise significantly increased the peak expiratory flow in asthma patients.

Published: January 2023

Objective: To determine the work engagement levels of hospital nurses and the predictive roles that nurses’ personal and organizational characteristics play.

Methods: A cross-sectional design was employed in this study, which included 549 nurses working in the Central Philippines. Nurses were selected through purposive sampling, and a self-report questionnaire outlining personal and organizational characteristics was employed. The Utrecht Work Engagement Scale (UWES) was applied to gather data about nurse engagement.

Results: The dedication score was the highest among the three dimensions of engagement while the vigor score was the lowest. Overall, Filipino nurses experienced an average level of work engagement. We observed significant relationships between a nurse’s age, years of experience in nursing, years in their present unit, and their position at work and their levels of engagement, vigor, sense of dedication, and absorption. Hospital capacity was a negative predictor of vigor, dedication, absorption, and overall work engagement. Further, the type of nursing contract was a negative predictor of vigor and dedication. The type of hospital and the nurse’s position were positive predictors of vigor, dedication, and absorption.

Conclusions: Filipino nurses were satisfactorily engaged at work. A number of nurses’ personal and organizational characteristics play a predictive role in their work engagement. Thus, nursing administrators must support, develop, and implement activities and measures that engage nurses at work.

Objective: To evaluate the efficacy of Tian dan shu gan rehabilitation exercise in improving the short-term survival quality of patients after percutaneous coronary intervention (PCI) and explore whether patients’ symptoms, physical function, cognitive function, and psychosocial function are improved after this exercise.

Methods: Patients with acute myocardial infarction who underwent PCI in Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine from August to November 2020 were selected. A total of 110 patients were selected by the convenience sampling method. Patients in the control group were given routine nursing measures after PCI for coronary heart disease, and patients in the experimental group received Tian dan shu gan rehabilitation exercise in addition to routine nursing.

Results: After 3 wk, the quality of life in the experimental group was improved compared with that in the control group, and the differences in symptom scores, physical functions, cognitive functions, and psychosocial functions were statistically significant (P < 0.01). After 3 wk of Tian dan shu gan rehabilitation exercise, patients with body mass index (BMI) between 27 and 29.9 had the highest score of body function, which was statistically significantly better compared with that of other groups (P < 0.001). Patients who had remained bachelors for a long period of time had the highest score of symptoms, which was statistically significant compared with the other groups (P < 0.001). The nursing satisfaction of the experimental group was 96.3%.

Conclusions:
Tian dan shu gan rehabilitation exercise was effective in improving the short-term quality of life of patients with acute myocardial infarction after PCI, and the nursing satisfaction rate was high, use of which should be further extended to more clinical patients.

Published: January 2023

Objective: Reproductive health (RH) rights are the rights of all persons, regardless of age, sex, or other traits, and they have the freedom to make decisions about their sexuality and RH. However, there is limited information about Ethiopians’ understanding of RH rights. Because little is known about the degree of knowledge and relevant predictors in the study area, this study was carried out to fill in the gaps.

Methods: An institution-based cross-sectional study was conducted from 3 January to 25 January 2021 G.C to determine the knowledge level of RH rights and its associated factors among Wolkite University undergraduate medical students. The minimum estimated sample size was computed by using the simple population proportion formula of 95% confidence interval (CI), with 5% of marginal error, which was 318 students. The students were stratified based on their academic year and department. Each student was selected from each department by using the simple random sampling method based on their ID numbers. Data were collected by using a pre-tested, structured self-administered questionnaire. Epi Info version 3.5.1 was used for data coding, entering, and cleaning, and then the data were exported to Statistical Package for Social Sciences (SPSS) version 23 for advanced analysis. The associated factors were identified by performing analysis for bivariate and multivariate logistic regression analyses.

Results: More than half (56.33%) of the participants were knowledgeable about reproductive and sexual rights and participated in RH clubs (adjusted odds ratio [AOR]: 2.94, 95% CI: 1.46, 5.91). The paternal educational level (AOR: 2.89, 95% CI: 1.34, 5.65) had an association with the knowledge of reproductive health rights.

Conclusions: The students’ knowledge regarding reproductive and sexual rights was found to be little. The Ethiopia Ministry of Education has to include reproductive and sexual rights in the curriculum of high school and higher institution studies.

Objective: To explore the current status and development of long-term care (LTC) research in terms of publications in China and Australia, to identify the major contributing authors and institutions, and to compare the research hotspots and trends between China and Australia in order to encourage informed collaborations and work in future.

Methods: We collected bibliometric data on the LTC of the elderly in China and Australia from 2009 to 2020 using Chinese National Knowledge Infrastructure (CNKI) and Web of Science (WOS). CiteSpace software was used to analyze co-authorships, co-institutions, and co-keywords.

Results: A total of 826 articles in Chinese and 393 in English were included for analysis. The total number of publications showed an upward trend in both countries. The top 10 productive researchers and institutions in China and Australia were identified, and their collaboration network was revealed. Then, the knowledge maps of cooccurring keywords, respectively, showed the hotspots of “LTC insurance, disabled elderly, combination of medical and health care, nursing home” and “nursing home, dementia, quality of life, intervention” in China and Australia. Strong citation burst keywords illustrated the emerging trends of “combination of medical and health care, healthy aging” in China and “polypharmacy, prevention” in Australia.

Conclusions: This article provided an insight into LTC of the elderly in China and Australia, and research in this field is developing rapidly and is being increasingly valued. The findings will be useful for future researchers to facilitate collaboration, identify new topics, and support urgently needed research of LTC in China.

Authors: Piskunov S. , Lisovski O. , Gopejenko A. , Trinkler L. , Chou M.M.C. , Chang L.W.
Published: January 2023

In this research, density functional theory accompanied with linear combination of atomic orbitals (LCAO) method is applied to study the atomic and electronic structure of wurtzite and rocksalt ZnxMg1−xO pseudobinary compounds in their bulk phases. Calculated band gaps of ZnxMg1−xO solid solutions under study are further validated by means of spectroscopic ellipsometry and optical absorption. In agreement with an experiment, it is predicted that increase of Zn content in ZnxMg1−xO leads to narrowing of its band gap for both wurtzite and rocksalt phases. The calculated infra-red (IR) spectra show that the IR peaks are shifted towards larger frequencies along with decrease of Zn content. Presence of imaginary phonon frequencies in rocksalt ZnxMg1−xO of x > 0.625 allows us to suggest that it is necessary to use properly oriented substrates for epitaxial growth to overcome polycrystallinity inZnxMg1−xO thin films at concentration x = 0.4 – 0.6.
Complex Type II Solar Radio Event on 4 July 2022
Authors: Kallunki J.
Published: January 2023

On 4 July 2022, a complex low-frequency solar radio burst was observed in Metsähovi Radio Observatory of Aalto University. The radio burst was observed at a frequency range between 20 and 80 MHz. In GOES (Geostationary Operational Environmental Satellite) class, the event was classified as C5.1. However, coronal mass ejection (CME) was not associated to this event. The observed radio burst was a long-lasting (~10 minutes) event, and it could be mainly classified as type II solar radio event. Also type III solar events were observed before long-lasting type II event. The event includes common frequency drifting emission structures, both fundamental and harmonic structures, but also rarely observed continuum-like or stationary structure. It is assumed that the continuum-like radio emission structure is originated from the stationary flare (coronal) loop, which was visible over the whole event. The drifting emission structure means accelerated electrons, which are produced by the shock related phenomena. The paper provides the observations from this event on radio wavelength, and also soft-X-ray regime and optical wavelength (AIA 171). In addition, a possible, simplified scenario is presented for forming the drifting and continuum solar radio emissions in type II solar burst.

Published: January 2023

To make informed decisions, modern society, like modern business, must operate with adequate information about many complex interrelated aspects of its activities. Land use is only one of such aspects. Agricultural lands are of particular importance today. Land data are needed to analyse environmental processes, as well as end unsystematic, uncontrolled use of agricultural land, environmental degradation, destruction of important wetlands, loss of fish diversity and destruction of wildlife habitats. To solve these problems, it is advisable to conduct regular analysis and evaluation of land resources, justification and analysis of factors influencing the agricultural land market in the country. The tasks were solved using multidimensional statistical methods, in particular, factor analysis, which helped to get rid of subjectivity in the choice of factors influencing the market under study. Based on the model of influence of factors on the national market of agricultural land in Ukraine, six main factors were identified, the most influential of which were the components of agricultural development (first factor) and, to a lesser extent, the component of vegetable production and yield (fourth factor). The interrelationships and the degree of influence of the selected factors on the main indicators of the agricultural land market, namely, on the area of purchase and sale plots, the price of purchase and sale plots, and the number of transactions were also analysed.
The evolving energy landscapes of coal: Windows on the past and influences on the future
Authors: Pasqualetti Martin J. , Frantál Bohumil
Published: January 2023

Coal energy landscapes have changed dramatically over the last decades, including geographic shifts in production and consumption, technological changes that have reduced labour demand and led to relatively new mining practices (e.g. invasive mountain-top approaches), changed economic footprints, a shutdown of capacities or a complete end of mining in many regions with massive impacts on regional and local economies, community well-being, social capital, et cetera. Then the Covid-19 pandemic and Russia´s invasion of Ukraine have fundamentally affected the global economy, disrupted energy markets, and shattered existing estimates about development trends, challenging the progress and speed of the low-carbon energy transition and coal phase-out. This article provides a brief reflection on the changing landscapes of coal and their possible futures, and serves as an introduction to the Special Issue of Moravian Geographical Reports on “The death of coal in the energy transition? Regional perspectives”.
Diverse responses of coastal communities to offshore wind farming development in Southern Spain
Authors: Frolova Marina , Pérez-Pérez Belén , Herrero-Luque Daniel
Published: January 2023

Despite having one of the fastest rates of wind power growth in Europe, offshore wind power development in Spain has been relatively slow. One of the factors affecting its deployment is strong local opposition. In this paper, we explore the main factors affecting local perceptions of offshore wind farms in the coastal regions of Southern Spain. We also compare local opinions of on-land and offshore farms, their impacts on local landscapes/seascapes, and their compatibility with local practices and values. To this end, a multi-phase research approach was applied, based on several stages of data collection and analysis and on surveys conducted between 2012 and 2022. Our study shows that the conflicts surrounding offshore wind farms are linked to the perception of the sea and the wind as important local resources and the perceived right of the coastal region to use these resources to generate wealth for their communities. The coastal communities’ values, perceptions, and practices regarding the sea have a fundamental influence on their opinions. Our research indicates that local people are more likely to accept offshore wind farms if they provide socioeconomic benefits for their communities and if joint use of marine resources can be guaranteed.

Published: January 2023

This study explores the use of powder plasma transferred arc welding (PPTAW) as a surface layer deposition technology to form hardfaced coatings to improve upon the wear resistance of mild steel. Hardfaced layers were prepared using the PPTAW process with two different wear-resistant powders: PG 6503 (NiSiB + 60% WC) and PE 8214 (NiCrSiB + 45% WC). By varying the PPTAW process parameters of plasma gas flow rate (PGFR) and plasma arc current, hardfaced layers were prepared. Microscopic examinations, penetration tests, hardness tests, and abrasive wear resistance tests were carried out on the prepared samples. Hardfacings prepared with PG 6503 had a hardness of 46.3–48.3 HRC, while those prepared with PE 8214 had a hardness of 52.7–58.3 HRC. The microhardness of the matrix material was in the range of 573.3–893.0 HV, while that of the carbides was in the range of 2128.7–2436.3 HV. The abrasive wear resistance of the mild steel was improved after deposition of hardfaced layers by up to 5.7 times that of abrasion-resistant heat-treated steel, Hardox 400, having a nominal hardness of approximately 400 HV. The hardness and wear resistance were increased upon addition of Cr as an alloying element. Increasing the PGFR increased the hardness and wear resistance of the hardfacings, as well as increasing the number of surface cracks. Increasing the plasma transferred arc (PTA) current resulted in hardfacings with fewer cracks but lowered the wear resistance.
