Are Geopolitical, Economy, and Social Affecting Unemployments? Evidence From ASEAN-5
Authors: Hatmaja Danang Tri , Fuddin Muhammad Khoirul
Published: February 2023

East and Southeast Asia gain tremendous economic and political advantages in terms of economic geopolitics (GPE). However, the impact that emerged in the GPE was further exacerbated by the emergence of the covid pandemic, "one belt, one road" in the global economic and geopolitical recession, which caused figures to soar in several ASEAN countries which is one of the challenges related to economic development. This study used the Vector Error Correction Model (VECM) based on de jure an  d de facto KOFGI panel data in ASEAN-5 from 1991-2019 to explore the short and long-term relationship between geopolitical, economic, and social factors on the unemployment rate. The results of this study reveal that the four variables have two co-integration relationships: especially in the long term, economic factors harm the unemployment, meanwhile, social and political factors have not provided a conducive influence to maintain the unemployment impact, and they promote no mutual mechanism benefit. The findings also show a negative correlation between political factors and an increase in de facto unemployment. It indicates that the political environment impacts a decrease in social and economic variables. Furthermore, the shock of the loss of de jure economic stability has adverse social and political interactions, thereby increasing the unemployment rate. This due to the critical role of economic stability to reduce the unemployment in ASEAN-5 countries.

The Indonesian consumer goods industry has been stagnant for four years 2014 – 2018 with the export average of only 5.5 trillion or equivalents to zero % growth. Since the government has been working hard for economic recovery during Covid 19 pandemic, the growth has grown to 20 trillion in 2021 (after the pandemic). Therefore, this research aimed to describe the influence of production and exchange variables on export growth of consumer goods industry in Indonesia. It used a linier regression method by using quarterly time series data of 2008 – 2021 which have been never studied before. The result showed that there found 78.80 % increase of export (cateris paribus) for 1 % production increase, 41.80 % increase of export for 1 % exchange rate increase, and 1 % of production and exchange rates increases caused 81.90 % increase in exports. Based on the explanation, there found a positive and significant effects between production and exchange rates on the export of consumer goods industry partially and simultaneously. It means that both factors are substantial and needed to be continuously improved in order to increase the export value of Indonesian consumer goods industry which in the end will also have positive impact on its growth.

Sexual Minority Youth E-Cigarette Use
Authors: Azagba Sunday , Ebling Todd , Shan Lingpeng
Published: February 2023

BACKGROUND AND OBJECTIVES

There is consistent evidence that sexual minority youth (SMY) use more traditional cigarettes than their non-SMY counterparts. However, there is relatively less information on e-cigarettes and, importantly, differences between and within SMY populations by race and ethnicity and sex. This study examines e-cigarette use by sexual orientation status and the intersection of race and ethnicity and sex.

METHODS

Data come from high school students in the 2020 and 2021 National Youth Tobacco Surveys (N = 16 633). Current e-cigarette use prevalence by sexual identity categories was calculated for racial and ethnic subgroups. Multivariable logistic regression analysis examined the association between sexual identity and e-cigarette use by race and ethnicity groups and sex.

RESULTS

E-cigarette use prevalence was higher for most SMY racial and ethnic groups than their non-SMY counterparts. However, multivariable logistic analysis showed varied results by race and ethnic groups, with higher e-cigarette use odds for SMY populations, although not statistically significant for some race and ethnic groups. Black gay or lesbian (adjusted odds ratio: 3.86, 95% confidence interval, 1.61–9.24) and bisexual (adjusted odds ratio: 3.31, 95% confidence interval, 1.32–8.30) high school students had significantly higher e-cigarette use odds than Black heterosexuals. Non-Hispanic Black females e-cigarettes use odds are 0.45 times that of non-Hispanic white males, and non-Hispanic other gay or lesbian had 3.15 times higher e-cigarette use odds than non-Hispanic white heterosexuals.

CONCLUSIONS

E-cigarette use is more prevalent among SMY populations. Disparities in e-cigarette use vary depending on race and ethnicity and sex.

Published: February 2023

Background: Transcatheter mitral valve repair (TMVR) using the MitraClip has become a well-established interventional therapy and is usually performed in elderly patients. The objective of this study was to assess 2-year clinical outcomes of TMVR in patients aged <65 years at three heart centres with severe mitral regurgitation (MR) and no surgical options. Methods: A retrospective study analysed data of 36 patients aged <65 years treated with TMVR . All patients were refused surgery by Heart Team decision. Baseline MR was assessed by biplane vena contracta width in two perpendicular views (mean 8.35 ± 1.87 mm). Degenerative MR was detected in 11 patients (30.6%); functional MR was detected in 25 patients (69.4%). Results: Acute procedural success was accomplished in 88.9% of patients. No procedure-related mortality during the first 30 days was detected. Over an average of 2 years of follow-up, all-cause mortality was 19.4% and cardiovascular death was 11.1% owing to advanced heart failure. The average follow-up period was 25.8 months (median was 20 months). Statistically significant difference (p-value <0.01) was detected for N-terminal prohormone of brain natriuretic peptide (pg/ml) at baseline (mean 9,870 ± 10,819; median 7,748) compared to follow-up visits (mean 7,645 ± 11,292; median 3,263). New York Heart Association functional class improvement was achieved in 69% of patients. A second intervention (reclipping) was required in two patients to correct recurrent significant MR. Conclusion: TMVR in patients aged <65 years refused surgical repair provides satisfactory clinical outcomes at 2 years. Future studies should evaluate the outcomes of MitraClip in this population in a larger cohort.

The community economic empowerment program at the oyster mushroom cultivation center in Village X which is run by the UM Amil Zakat Institution (LAZ) is intended to improve the economy of the target community. In the process, an economic empowerment program requires an analysis of the organization and its environment so that future program strategies can be identified. Aims to describe and analyze the strengths, weaknesses, opportunities and threats in a community economic empowerment program, this study uses qualitative methods, with a descriptive research type. Information regarding the strengths, weaknesses, opportunities and threats of program management was taken through literature studies related to LAZ, economic empowerment, and swot analysis; the observation was carried out at the oyster mushroom cultivation center; as well as in-depth interviews involving members, administrators, center managers, LAZ UM, residents around the center and local government. The results of the study indicate that there are several strengths, including the large quantity of human resources, support from stakeholders and members. The weaknesses of this program are communication problems between the institution and the community, and the lack of a 'sense of belonging' to center members. In fact, there are various opportunities such as oyster mushroom product diversification, opportunities to establish new partners, and the creation of other activities that can be developed through oyster mushroom cultivation centers. In addition, the existence of this program is inseparable from threats from outside the center, namely the existence of a group of people who are considered to want to destroy the center's business and reduce consumers.

Therefore, it is necessary to have a regulation for the implementation of online business in Indonesia. This study aims to see how the Information and Electronic Transaction Law (UU ITE) is present in business development in Indonesia, especially for consumers. This research will be carried out using a normative juridical approach. The data used in this research comes from various previous research results and several legal sources in Indonesia, especially the ITE Law. The results of this study then found that article 4 in the Consumer Protection Act (UUPK) explains various rights owned by consumers. Then specifically, the ITE Law explains how to protect consumers that occur in the realm of online transactions. The presence of the ITE Law, despite its controversy in Indonesian society, can save consumers from conducting online business in Indonesia.

Authors: Triwibowo Agung
Published: February 2023

Indonesia dengan lebih dari 60% wilayah laut yang luas terbentang dari Sabang hingga Merauke memiliki banyak keanekaragaman sumber daya perairan yang sangat kaya. Salah satunya adalah terumbu karang yang harus dijaga kelestariannya. Terumbu karang adalah salah satu ekosistem laut dan pesisir yang memiliki peranan penting karena memiliki nilai ekologi dan ekonomi yang tinggi. Tingginya nilai-nilai tersebut membuat keberadaan ekosistem terumbu karang menjadi terancam akibat penyebab antropogenik seperti polusi yang mencemari perairan, aktivitas penangkapan ikan yang melebihi kapasitas, eutrofikasi, praktik penangkapan ikan menggunakan alat tangkap yang tidak ramah lingkungan. Rusaknya ekosistem terumbu karang tidak hanya menurunkan kuantitas dan kualitas terumbu karang, tetapi juga mengurangi jumlah organisme lain yang berinteraksi dan hidup di sekitar terumbu karang. Untuk menjaga kelestarian ekosistem terumbu karang, perlu dilakukan langkah-langkah pencegahan berupa kebijakan dalam perlindungan dan pengelolaan terumbu karang serta organisme laut untuk melindungi lingkungan laut dari pengaruh yang merugikan.

DESAIN BUBU BOLA UNTUK PENANGKAPAN SPINY LOBSTER (Panulirus sp.) SECARA BERKELANJUTAN
Authors: Nababan Sakti Pandapotan , Hermawan Maman , Suyasa I Nyoman
Published: February 2023

Operasi penangkapan lobster di Indonesia masih dilakukan dengan cara penangkapan yang cenderung tidak ramah lingkungan. Penggunaan jaring insang dasar dan krendet yang mendominasi pada upaya penangkapan lobster dinilai masih kurang selektif dan berpotensi mengakibatkan ghost fishing. Hal ini karena dasar perairan yang didominasi dengan substrat berpasir, berkarang dan berbatu membuat jaring sering tersangkut dan saat diangkat akan ada bagian badan jaring yang tertinggal. Jaring yang tertinggal ini masih tetap memiliki kemampuan untuk menangkap lobster, hanya saja sudah tidak dalam kendali manusia. Perancangan perangkap lobster yang dinilai lebih selektif dan ramah lingkungan dilakukan dengan metode observasi dan wawancara dengan mempelajari perkembangan alat penangkap lobster di dunia, permasalahan pada alat penangkap lobster yang ada saat ini serta mempelajari tingkah laku lobster. Bentuk bubu menyerupai bola berbahan HDPE, dengan dinding dari dasar bubu sampai 8 cm ke atas adalah dinding bertekstur polos. Selebihnya sampai pada mulut bubu dibuat lubang-lubang agar lobster dapat memanjat bubu. Tujuan dari desain ini agar lobster yang mampu memanjat bubu hanya lobster kategori layak tangkap. Ketinggian 8 cm ini dibuat berdasarkan hasil pengukuran yang dilakukan secara manual pada beberapa ekor lobster layak tangkap yaitu > 7 cm, sehingga dianggap mampu menggapai lubang pada dinding bubu ini. Pengujian tahap awal pada desain ini dilakukan untuk memastikan bubu dapat sampai di dasar laut dengan posisi pintu menghadap ke atas serta desain pintu bubu mampu menghalangi lobster yang telah masuk untuk keluar dari bubu. Namun demikian desain ini masih harus dilakukan uji penangkapan di daerah penangkapan lobster dalam satu siklus penangkapan lobster.
Plant Use and Agriculture in Roman Italy
Authors: Feito Jessica
Published: February 2023

This article features an archaeobotanical meta-analysis of plant macroremains from the whole of Roman Italy. The aim is to further refine understandings of ‘Roman’ foodways, and to highlight the ways that Roman expansion impacted the core of the Empire itself. The study builds upon previous regional overviews by expanding the geographical focus, integrating fully quantified data and wild/weed seed analysis, and broadening the topical range so as to consider not only dietary patterns, but also agricultural practices and fuel use throughout Roman Italy.
The majority of the dataset is derived from published archaeobotanical reports, and consists of macroremains from archaeological sites in Italy dating from 500 BC to AD 500. In utilising such a broad chronological framework, changes in the plant repertoire may be better elucidated. The data are further divided according to geographical region and site type, and ancient literary sources are used to contextualise patterns observed in the dataset.
The findings shed light on diverse agricultural practices, as well as trends effecting the distribution of key cash crops, which suggest that imperial expansion may have affected the olive oil and wine industries differently. Other observations include regional variations in consumption patterns and cultural preferences for specific nut varieties. A peak in dietary diversity can be observed in the Roman Imperial period, followed by a decline in the Late Roman period.

HVPT develops new phonemic categories by exposing learners to a variety of productions of new phonemes. Results indicated significant improvement in perception of Arabic consonants (pre-test mean = 58.5%, post-test mean = 64.8%, difference = 6.3%, w = 11, z = –1.36). Improvements were specifically seen for the contrasts /d-d/, /k-q/ and /h-h/. No significant relationship between HVPT outcomes and language learning variables was found. Overall results of the study indicate the effectiveness of training perception of Arabic phonemic contrasts in English-speaking learners of the Quran.
A longitudinal case study on the development of consonant–vowel distribution in the babbling of a Czech–English infant
Authors: Cilibrasi Luca , Dunková Jirina
Published: February 2023

Previous studies have shown that bilingual infants adjust the distribution of vowels and consonants, while babbling, to the languages they are exposed to, but little is known about the developmental trajectory of this skill. In this study, an infant exposed to English and Czech from birth was recorded every two/three days from the age of 0;6.13 to the age of 1;6.21 while babbling, and the distribution of vowels and consonants was analysed in his speech in relationship to the person he was interacting with. The study shows that the proportion of consonants increases throughout development in the recordings in which the child is interacting with his father (Czech speaker), and it remains instead stable over development in the recordings in which the child is interacting with his mother (English speaker). This finding suggests that the child is able to tie his babbling strategies, within a few months, to the distribution of vowels and consonants occurring in the linguistic environment.

Patterns of production of Spanish and English laterals by early sequential Spanish–English bilinguals (L1 and L2 respectively in the order of acquisition) were investigated. A total of 25 early Spanish–English bilinguals, who are all English-dominant (average age of L2 acquisition: 3;9), were recruited. They were recorded while reading sentences aloud in Spanish and in English containing laterals in onset and coda positions adjacent to front and back vowels. Target words with laterals were spectrographically analysed through an investigation of F1 and F2 values. The measurements obtained were compared between the two languages. The results show that the participants maintain separate acoustic realizations for the laterals in all four different phonetic environments in their two languages. Since their lateral productions are mixed with respect to the influence of the two languages, the results suggest that bilinguals’ interrelated systems influence each other at a fine-grained acoustic level.

The work is devoted to the development of new compositions of a heat-resistant thermal barrier coating for parts of gas turbine engines and gas turbine plants. The main existing materials and technologies for applying heat-resistant thermal barrier coatings are presented, and promising materials for the production of heat-resistant thermal barrier coatings are presented. The proposed new composition of the heat-resistant thermal barrier coating is a four-layer composition: as the first two heat-resistant bonding layers, materials based on nickel with the addition of aluminum, chromium, yttrium, rhenium, hafnium are used; in the last two layers, materials based on zirconium dioxide with the addition of rare earth metal oxides were used. The results of comparative tests for thermal cyclic resistance, isothermal heat resistance of samples from a superalloy based on nickel with a new composition of a heat-resistant thermal barrier coating and compositions existing at JSC "UEC-Perm Motors" are presented. And also measured the thermal diffusivity by the method of laser flash of samples from a superalloy based on nickel with a new and one of the existing at JSC «UEC-Perm Motors» compositions of the heat-resistant thermal barrier coating. The use of the developed composition of a heat-resistant thermal barrier coating makes it possible to significantly increase the service life of parts of the hot part of gas turbine engines and gas turbine plants, as well as to ensure the performance of parts on new and promising products with an increased operating temperature. Today, in conditions JSC «UEC-Perm Motors», a new composition of a heat-resistant thermal barrier coating is used in the manufacture of gas turbine plants and gas turbine engines based on PS90-A.

The paper describes the results of a set of statistical data on damage as applied to various structural zones on the application of low-speed impact damage to full-size parts made of polymer composite materials of an aircraft engine to work out the statistics. For this type of work, an installation for application of the required low-velocity impact damage, similar to a pendulum- type copter, has been developed; the developed installation allows application of low-velocity impact damage in a certain range of energies. When performing the work, different zones of the structure (regular shell, flange thickenings, places of thickness change, etc.) were taken into account, the damage was applied taking into account the selected zone. Based on the results of the work, a set of statistical data of applied damage (geometric dimensions, impact interaction characteristics, visual differences) for different structural zones of the structure was obtained, statistical analysis of the obtained test results with determination of average values, standard deviations and variation coefficients of damage depth and maximum diameter was performed. The results of the work are presented in the form of plots of dependences of geometric dimensions of the damage on the actual impact energy. The presented approach to low-velocity impact damage, which is based on the use of full-size structures as test objects, makes it possible to unambiguously determine the required parameters of impact damage to be taken into account when planning the experiment and when substantiating the static and fatigue strength of the structure.

Now, without exaggeration, it is possible to assert the existence of a new powerful alternative that has come to replace the physical experiment. Methods of computational fluid dynamics allow you to solve a large list of practical problems. However, an important issue of any numerical study is the assessment of the adequacy of the numerical forecasts obtained. When conducting a numerical study, you need to start with solving a test problem, the solution of which is already well known from earlier and reliable studies (in-situ or analytical). When solving a test problem, the mathematical model is configured and verified. In this connection, this paper presents the results of numerical simulation of the flow of configurations of annular air intake device located in the inter-caliber space with various geometric parameters of the central body, which determine the main parameters characterizing their gas-dynamic perfection. The method of conducting a computational experiment to determine throttle characteristics is shown. Based on a comparison of calculations with experimental data, a conclusion is made about the possibility of using the ANSYS Fluent software package for further use in solving similar problems.

This article discusses the modeling of the stress-strain state of products during laser powder surfacing using the example of a stepped tubular sample. To calibrate the model, a number of experiments were carried out using an additive powder with a fractional composition of 40–80 μm. During laser powder surfacing of samples, two-point thermometry was carried out, which is necessary for the subsequent calibration of the temperature problem. Powder surfacing was carried out in one layer with pauses between the deposited paths according to the surfacing modes. Helium and argon were used as shielding gases. The creation of an applied tool for the preliminary numerical assessment of warpage and residual stresses in blanks and DSE before carrying out repair technological operations using the powder laser cladding method, which allows for prompt approximate calculations, was the main task of the work. In the model, the element birth/death method was considered, which makes it possible to implement the appearance of hardfacing bodies and is the most convenient in this case. Warping modeling was carried out by dividing the welded part into tracks, which, in turn, are divided into hardfacing bodies. The next stage is the heatingand cooling of each elementary body along the surfacing trajectory, instead of modeling a moving heat source. Command inserts allow you to adjust the surfacing trajectory using automatic numbering of elementary bodies. The proposed technique makes it possible to quickly preprocess the problem and obtain sufficiently accurate calculation results in a short time. The results of modeling and real laser powder surfacing were compared. Verification of the developed model was carried out using the digitized outer surface of the existing experimental samples after surfacing. Calculations show sufficient computational accuracy of the model, however, the use of high-temperature properties of the powder material will reduce the calculation error.
