Sustainable business development through sufficiency economy practice : a case study of Thai listed companies
Authors:   , Korphaibool Veerawin
Published: April 2023

The purpose of the research is to determine the sufficiency economy philosophy (SEP) performance through annual and sustainable development reports and simplify the outcomes by representing through a scoring system. Each of the SEP elements was aligned with each GRI sub-topic to generate a SEP scoring system. Then, the results from the scoring system were verified by testing the relationship between SEP performance and firm-specific risk of 34 Thai listed companies from 2013 to 2018 via panel data analysis. The global reporting initiative (GRI) standards were used as the fundamental scoring system as it's widely used and accepted in academic and business sectors. Univariate analysis results suggested that firms with high SEP scores generated a higher return on equity and paid a higher dividend payout ratio to the shareholders. The SEP scores were used to test two hypotheses of risk reduction and managerial opportunism. The hypotheses were tested using fixed effects regression and the results supported the risk reduction hypothesis and this practicing SEP reduced firm-specific risk. To validate the results, a two-stage least squares instrumental variable (2SLS-IV) analysis was performed to estimate the causal relationship between SEP performance and firm-specific risk. The results remained negatively and significantly correlated, indicating that SEP practice stimulated business sustainability. The findings suggested that the SEP scoring system was able to capture SEP performance and practicing SEP appeared to reduce firm-specific risk, which was consistent with the risk reduction hypothesis of the stakeholder theory. In summary, The SEP practice had a significant impact on reducing firm-specific risk and increased firm profitability. Implementing SEP can lead firms toward sustainability and increase strength from adopting the SEP three cores and two underlying conditions.
Perspectives and challenges of green hotel in Thailand
Authors:   , Sangmanee Pornwajee
Published: April 2023

The hotel business is intense resource consumption such as water, energy, and non-durable products to delight customers, leading to environmental problems. With this regard, the transformation of the green hotel and environmental saving programs can dwindle the hotel property's adverse impacts. The purposes of this paper are 1) to study the perception of hotel practitioners and stakeholders toward the critical challenges of green hotel transformation and 2) to propose the recommendations for green hotel operations and certification scheme in Thailand. The study employed mixed methods to collect the data. The in-depth interviews were along with field observation; the interviews data were conducted with ten persons of green hotel practitioners, three non-green hotel practitioners, and a representative from a governmental agency to identify the obstacles of green hotel development. Besides, the study distributed online questionnaires to 192 Thai and Non -Thai travelers to explore their experiences of green hotel staying and selection decisions. A content analysis, descriptive analysis, and chi-square test were employed. The in-depth interviews results indicated that the critical challenges of green hotel transition were a high investment in resource consumption and energy efficiency systems, staff training, monitoring process, and lack of government upholds that make the hotelier uncertain. Scoping on the online survey found that customers mainly concern about price and hotel location, which is the rationale of green hotel selection cutting off. Besides, an education level was a sole factor that correlates with the green hotel staying decision. To encourage and enlarge the green hotel transition in Thailand and customers decision process in green hotel staying, green hotel stakeholders and the governmental agencies should work closely in providing incentives, establishing promotion campaigns as well as providing educational green hotel information at national and international levels that can lead to long-term success of a green hotel in Thailand.

Authors:   , Thimkam Thanakorn
Published: April 2023

The purpose of this experimental study was to evaluate wear characteristics and retention force of the RetenDent mini-implant overdenture system (Chulalongkorn product) after the insertion-removal fatigue test. One-piece mini-implants attachment system for overdenture, Osstem MS denture® type implant (OSSTEM, Germany GmbH), and RetenDent mini-implant were tested. All samples were subjected to repeated insertion and removal fatigue cycles by the universal testing machine (E1000, INSTRON Instrument, England). Subjected fatigue cycles were 5500 with 1.00Hz frequency to mimic a 5-year insertion and removal three times per day. The retention force was measured by separating the O-ring from the abutment and recorded with the universal tester (EZ-SX, SHIMADZU, Japan). The retention force was measured six times, at baseline and the end of 1100, 2200, 3300, 4400, and 5500 cycles. These represent each year of use. After fatiguing, the O-rings and mini-implant ball abutments were examined with a stereomicroscope (SZ61 OLYMPUS, Japan) and compared to baseline. The result showed a mean retention force of 6.65N for the RetenDent group and 6.84N for the Osstem group, which were not statistically different. The two attachment systems had no significant effect on retention force. However, the fatigue cycles alone and the interaction between the attachment system and fatigue cycles had significant effects on retention force. The RetenDent group’s retention was significantly higher at baseline (10.96N) and after 1,100 cycles (8.73N) compared to the Osstem group (6.50N and 6.66N). There was no statistical difference at 2200 cycles. The Osstem group’s retention became significantly higher after 3300, 4400, and 5500 cycles (6.86N, 7.06N, 6.997N) compared to the RetenDent group (5.04N, 4.49N, 3.88N). In conclusion, the RetenDent and the MS denture® mini-implant attachment system provided a similar 5-year average retention force at higher than the minimum recommended for overdenture. The RetenDent group had significantly higher retention forces at the first two-point of measure. There was no wear on the ball abutment of both groups under the stereomicroscope after 5,500 fatigue cycles.

Published: April 2023

The core values of the French society comprise of liberty, democracy and equality. However, there seems to be limitation and social inequality when it comes to be "elite training schools". These privileged training and selection systems of French civil service seem to be a unique French practice. The elite training schools, especially L'Ecoles Nationale d' Administration, represents inequality in French society and, therefore, presents a problem for French politics. This study analyzes (1) the relationship between French elite training schools and French state; and (2) the important of the ENA for French politics. The result of this research shows an important of the ENA for the French political and private sectors which complicates any attempt to reform it.
Effect of RD43 rice (Oryza sativa L.) On starch digestibility, physicochemical properties, glycemic responses and food applications
Authors:   , Suklaew Phim
Published: April 2023

RD43 rice (Oryza sativa L.) is a cross-breed between Khao Jow Hawm Suphan Buri and Supan Buri1. It is characterized as a low amylose content, soft texture, and mild fragrance. However, its potential of metabolic health effect and food application remains unknown. In the present study, daily consumption of RD43 rice containing 14.10 g of undigestible starch for 12 weeks showed a significant reduction in fasting plasma glucose, insulin, HbA1c, and HOMA-IR in prediabetic participants. Furthermore, a significant decrease in body composition including body weight, body mass index, total body fat, and waist circumference was observed after the consumption of RD43 rice at 6th and 12th week. In comparison with conventional rice in Taiwan (Taiken9), ingestion of RD43 rice showed a significantly reduction in fasting plasma insulin and HOMA-IR at 12th week. In physicochemical and functional properties found that RD43 rice flour had higher amylose content (19.04%) than Hom Mali rice flour. It presented an irregular polyhedral shape and manifested a V-type crystalline structure and less crystallinity, which lead to a significant reduction of the water absorption index (WAI), swelling power (SP), water solubility index (WSI), gelatinization temperature, and pasting properties. Moreover, it had lower starch digestibility than Hom Mali rice flour due to a lower content of rapidly digestible starch (RDS) and higher content of undigestible starch. RD43 rice flour also exhibited a greater ability to disrupt cholesterol micellization and bind bile acids. In food application, steamed muffin made from RD43 rice flour showed lower starch digestibility than Hom Mali steamed muffin with no alterations of sensory attributes. Moreover, the substitution of wheat flour with RD43 rice flour (10-40% w/w) into noodles decreased starch digestibility, hydrolysis index, and RDS content together with increasing undigestible starch content. Comparing to the control noodles, 30% RD43 rice flour noodles slightly elevated WAI, swelling index (SI), cooking loss, and lightness (L*) as well as reduced redness (a*), yellowness (b*), and hardness with similar overall acceptability. In healthy men, consumption of 30% RD43 noodle caused a reduction in postprandial plasma glucose with increasing postprandial glucagon-like peptide-1 (GLP-1) and peptide tyrosine–tyrosine (PYY). In conclusion, RD43 rice has potential for food manufacturing and controlling glycemic, appetite as well as body composition in humans.

Authors:   , Aksornchu Pattamaporn
Published: April 2023

Several studies have reported the benefits of anthocyanin-rich berries on improving human health. However, the effect of Thai berries on delaying carbohydrate digestion, antioxidant properties, glycation inhibition, and anti-adipogenesis have not been investigated. Therefore, the present study aimed to determine the potential of anthocyanin-rich Thai berry extracts from Antidesma bunius or Mamao (ABE), Lepisanthes rubiginosa or Mahuat (LRE) and Syzygium nervosum or Makiang (SNE) on the inhibition of carbohydrate digestive enzymes, the antioxidant activity, anti-glycation, and anti-adipogenic property. In this study, total phenolics, total anthocyanins, and cyanidin-3-glucoside (C3G) contents of the anthocyanin-rich Thai berry extracts were 237.90-300.91 mg GAE/ g extract, 32.45-66.86  mg C3G/ g extract, and 27.19-39.96 mg/ g extract, respectively. Besides, ABE and LRE also contained delphinidin-3-glucoside with values of 21.65 and 0.93 mg/ g extract, respectively. All extracts demonstrated inhibitory activity against intestinal maltase and sucrase with IC50 values of 0.79 -1.52 mg extract/ml and 1.34-1.65 mg extract/ ml, respectively. It was found that ABE exhibited better antioxidant properties than LRE and SNE. Therefore, ABE was further investigated on the antiglycation and antiadipogenic properties. It was found that ABE (0.25 mg/ml) significantly reduced the formation of fluorescence and non-fluorescence AGEs (NƐ-carboxymethyl lysine, NƐ-CML) in fructose and glucose-mediated protein glycation. ABE prevented protein oxidation by reducing the protein carbonyl content and inhibiting protein aggregation by decreasing the β-amyloid cross structure formation. Furthermore, ABE (16 µg/ml) prevented 3T3-L1 cell differentiation. It reduced the intracellular triglyceride accumulation by the inhibition of adipogenic transcription factor expression, C/EBPα. Pparγ receptor contributed to reducing the mRNA expression of acetyl-CoA carboxylase (ACC), fatty acid synthase (FASN), and lipoprotein lipase (LPL). These findings suggested that Thai berry extract in this study, especially ABE, can be useful as a promising natural compound for delaying carbohydrate digestion, decreasing the monosaccharide-induced protein glycation and oxidative protein damage, protein aggregation, and preventing adipogenesis.

Authors:   , Supang Wirasinee
Published: April 2023

In this work, spent coffee grounds (SCGs) was used as the feedstock for biofuel production by supercritical ethyl acetate. The SCGs is waste obtained from coffee industrial that is continuously increasing every year. To make SCGs becomes more valuable, utilization of ethyl acetate as the extracting and reacting solvents for biofuel production via interesterification reaction. The characterization of SCGs sample showed that the moisture content of fresh SCGs was around 56 wt%. After oven drying, the moisture of SCGs was reduced to 12.76 %wt. To prolong the shelf-life of the sample and to minimize impact of hydrolysis on interesterification reaction, the drying step is required to reduce the water in SCGs. Ethyl acetate was a suitable solvent for coffee oil extraction from SCGs due to high recovery of coffee oil (22.74 wt%). The feedstock for biofuel production was the mixture of coffee oil and ethyl acetate at molar ratio of 1:30 that extracted at room temperature and atmospheric pressure. In biofuel production, two parameters were investigated for optimal condition. Temperature (275, 300, 325, and 350°C) and feed flow rate (2, 2.5, and 3 g/min) were controlled under pressure at 15.0 MPa. The amount of fatty acid ethyl ester (FAEE) in the product was measured by gas chromatography. The optimal condition was found at temperature of 350°C and feed flow rate of 2.5 g/min. The highest yield of FAEE is 86.44 wt%.
Geology and petrochemistry of volcanic rocks in the Lam Sonthi area, Lop Buri province
Authors:   , Uthairat Saowaphap
Published: April 2023

Lam Sonthi area is in Lop Buri province, central Thailand. Stratigraphically, the geology of the area consists of five rocks units; Unit I: Khao Ruak siltstone which is correlated to Khao Luak Formation (Early Permian), Unit II: Khao Phaeng Ma conglomerate, Unit III: Khao Ruak volcanics, Unit IV: Lam Sonthi polymictic conglomerate, and Unit V: Kuttaphet sandstone which is correlated to Phu Kradung Formation (Early Jurassic). In addition, the volcanic rocks, which are named as Kuttaphet volcanics and Khok Khli volcanics, could be found in the top of Unit IV as the polymictic intermediate breccia. Petrographic classification identifies the volcanic rocks according to their mineral constituents that quartz is found less than 20 %, so they are named as andesite. Clasts of Kuttaphet volcanics consist of plagioclase andesite and pyroxene-plagioclase andesite while clasts of Khok Khli volcanics consist of plagioclase andesite and hornblende-plagioclase andesite. The selected large clasts of these 2 volcanics were geochemically analyzed for major oxides and some trace elements using XRF and ICP-MS, then compared to the pyroxene-plagioclase andesite which is lava from Khao Ruak volcanics. Geochemistry of all samples suggests that the volcanic rocks in this area are andesite excluding plagioclase andesite clasts of Kuttaphet volcanics are composing of dacite/rhyolite. However, all samples are identified as calc-alkaline affinity and plotting of Ti-Zr suggests that they could have been originated in the volcanic arc setting and the N-MORB normalized patterns show negative Nb and Ta which could be suggest that the volcanic rocks in the Lam Sonthi area is associated with subduction zone. Geochemical similarities indicate that the clasts of Kuttaphet volcanics (which is pyroxene-plagioclase andesite) and Khok Khli volcanics (which are plagioclase andesite and hornblende-plagioclase andesite) were derived from the similar magma source of the Khao Ruak volcanics excluding plagioclase andesite clasts of Kuttaphet volcanics.
Stratigraphy and geochemistry of rock salt from Maha Sarakham formation in changwat Chaiyaphum, northeastern Thailand
Authors:   , Rattana Pranot
Published: April 2023

Maha Sarakham Formation is one of massive potash deposits in the Khorat Plateau extending from northeastern of Thailand to central of Lao PDR. Maha Sarakham Formation consists of three rock salt members (the lower, middle and upper members) interbedded with claystone. Potash minerals are associated with the thick bed of rock salt in the upper part of lower salt member. Previous studies are still under discussion on whether the origin of rock salt from marine or non-marine (hydrothermal origin and mixed fluids) deposit. The purpose of this study is to analyze the origin of rock salt based on elemental compositions and isotope analysis. In addition, stratigraphic correlations were done in five boreholes (K-201-205) located in Amphoe Bamnetnarong and Chaturat, Changwat Chaiyaphum, Thailand. As stratigraphical correlation results, the rock salt shows a dome structure. The limbs of salt dome are interpreted from lithostratigraphy correlations of K-201, K-202, K-203 and K-205 based on two beds of rock salt and potash zone in the lower salt member. The geochemical analysis of the lower and middle/upper rock salts in borehole K-203, and rare earth elements (REE) of claystone in five boreholes suggests that major and trace elements showing contents according to the formula of minerals and δ11B value (12.26‰ -32.62‰) indicates almost halite influenced seawater. However, the anomaly of carnallite by δ11B value (12.26‰) preferred possible influx of hydrothermal into the Khorat basin. REE of claystone are comparable with the REE in sandstone from the Simao Basin of China, the similar of REE pattern inferred the identical provenances both of clastic sedimentary rocks.

Authors:   , Ubaidillah Mohammad
Published: April 2023

In upstream oil and gas business, Indonesian has introduced Production Sharing Contract Cost Recovery (PSC CR) in 1966 and still implementing that fiscal system until nowadays. In January 2017, The Indonesian Minister of Energy and Mineral Resources (MEMR or ESDM) introduce new PSC system called Production Sharing Contract Gross Split (PSC GS) following with three amendments until 2019. Ministries believe this new Fiscal regime can attract more investor to invest Oil & Gas business in Indonesia by delivering three main values which are certainty, efficiency, and simplicity policies. This study evaluates and compares the financial aspect of new Indonesian fiscal regime called PSC GS with the former Indonesian fiscal regime PSC CR. In this study, financial analysis was performed to compare the output of both fiscal terms on thirty fields samples as case studies. The comparation use some of key financial parameters, for instance Net Present Value (NPV) and Internal Rate of Return (IRR) which can be calculated from project input such as oil production, gas production, investment cost, operational cost etc. using the formula from the structure of each fiscal regimes. According to the result, it can be concluded that for majority of the 30 samples, PSC CR will generate a better NPV and IRR for the contractor. Next, sensitivity analysis is done by calculating Net Contractor Take percentage in several different hydrocarbon price scenario as representative of unpredicted future. According to the result, even though both regimes are showing regressive fiscal, but in overall PSC GR are tends to be resulting a lower NCT with sensitively changing in different price condition, meanwhile for PSC CR tends to be resulting a higher NCT with more stable NCT percentage in various condition of oil and gas prices. These results can be quideline that selecting the right fiscal regime can be affect the result of contractor financial project profit.

Published: April 2023

Die Ziele dieser Masterarbeit bestehen darin, dass die gesprochensprachlichen Besonderheiten in Bereichen Phonetik und Syntax, anhand der 81 authentischen Gesprache im Korpus, Plattform Gesprochenes Deutsch”, erforscht warden. Ein weiteres Ziel ist die daraus resultierenden Befunde als Grundlage der Phanomenauswahl zur Gestaltung der Unterrichtsskizzen zu verwenden. Anschliebend warden die Vorschlage uber den Einsatz des Themas “gesprochenes Deutsch” im DaF-Unterricht gegeben. Aus der Untersuchung geht hervor, dass die Apokipe, die Verkurzung der Endsilbe und die Assimilation die drei haufigsten phonetischen besonderheiten sind. Hingegen sin dim syntaktischen Bereich die Ellipse, der Abbruch und Wiederholung und die Konstruktion weil mit Verbzweitstellung die drei haufigsten aufgefundenen syntaktischen Merkmale. Die Untersuchungsergebnisse der beiden Phanomenbereiche weisen deutlich eine Tendenz auf, dass einige sprachliche Komponenten beim Sprechen ausgelassen warden. Die Ursachen der moisten vorgefundenen Phanomene in beiden Bereichen warden unterschiedlich befrundet. Die Rechtfertigungen der moisten phonetischen Merkmale ligen darin, dass der weggelassene Laut den geringen Sonoritatsgrad besitzt. Im semantischen Hinblick deuten ferner andere Elemente in demselben Element auf die Interpretationshinweise hin. Im Bereich der syntaktischen Phanomene spielt bei der Ursachenbegrundung hingegen die Eingebundenheit der situativen Kontexte eine erhebliche Rolle.
Repeatability, reproducibility, agreement, and safety of tono-pen tip cover for intraocular measurement using latex and polyethylene wrap
Authors:   , Suvannachart Pukkapol
Published: April 2023

Background: Tono-Pen® is a regularly used device. A tip cover is needed to prevent damage to the transducer tip and patient-to-patient contamination. Ocufilm® (OF), latex disposable tip cover, is costly and able to cause allergic reactions. 

Objective: To evaluate repeatability, reproducibility, and agreement of intraocular pressure measurement with Tono-Pen® using OF and polyethylene wrap tip cover (PE) in human eyes.

Materials and Methods: This is a cross-sectional, experimental study. For the right eyes, 4 measurements using PE were done by two raters (A and B) in random order to assess intra-rater repeatability and inter-rater reproducibility. For left eyes, 4 measurements were done by rater A using both PE and OF in random order to assess intra-rater repeatability and agreement. 

Results: A total of 128 participants were recruited. The mean difference in mmHg (95% limits of agreement, intraclass correlation coefficient) was -0.34 (-3.04 to 2.36, 0.93) for repeatability of PE by rater A in the right eyes, -0.33 (-3.01 to 2.36, 0.93) for repeatability of PE by rater A in the left eyes, -0.02 (-2.88 to 2.83, 0.92) for repeatability of PE by rater B, 0.36 (-3.34 to 4.07, 0.90) for inter-rater reproducibility of PE, -0.42 (-2.75 to 1.91, 0.95) for repeatability of OF by rater A, and -0.71 (-5.18 to 3.76, 0.83) for agreement between both tip covers. The only complication was punctate epithelial erosion. No sight-threatening complications and allergic reactions were found. Cost minimization analysis found that PE had approximately 8-time decreased cost compare to OF.

Conclusions: For intraocular pressure measurement with Tono-Pen, PE demonstrated acceptable repeatability, reproducibility, and agreement with OF with a good safety profile.
Sonographic ductal changes and pertinent characteristics that associate with proliferative lesions of breast
Authors:   , Rengganis Anggraeni
Published: April 2023

Managing for sonographic focally thick duct lesions is not established in practice guidelines. Most cases showed scant cells on fine-needle aspiration (FNA). The study aimed to detect any variables that could predict proliferative lesions of the ducts and avoid unnecessary biopsies. A retrospective cohort design was done to analyze the association between ultrasound (US) variables and the outcome of proliferative or non-proliferative ductal lesions, determined by corresponding histopathology or cytology on consecutive follow-ups for at least three years. The data collection from 2015-2017 at King Chulalongkorn Memorial Hospital showed that 199 female patients with 210 index lesions met the eligibility criteria, 56.3% were the patients on screening (setting#1), 22.1% were examined for symptomatic lesions (setting#2), and 21.6% were treated breast cancer in follow-up (setting#3). The patients' age was categorized into <50 and ≥50 years old with a ratio of 53:47. The presence of the six associated US parameters was as follows; internal nodularity (65.7%), mixed echoic wall (41.0%), location at the periphery (69.0%), vascularity (35.2%), calcification (39.5%), and mean diameter of 4.50 (SD 1.43) mm. Of the final outcome, 71 cases had proliferative ductal lesions (18 of which were malignant). The non-proliferative disease was found in 66.2% of cases (52.4% yielded scanty cells on FNA). The regression model depicted vascularity as the single fixed predictor with an odds of 2.21 (95%CI 1.16, 4.19). The age cutoff at 50 and settings#2, #3 categories did not fit well when added to the model with OR of 1.17 (95%CI 0.62, 2.22), 1.87 (95%CI 0.90, 3.87), 0.55 (95%CI 0.23, 1.30), respectively.  In conclusion, feeding vessels are a pertinent parameter to be a predictor of proliferative lesions. Focally thick ducts without associated parameters seem not worrisome, and only observation is merited.

Published: April 2023

This research aims to explore the adaptation strategies for the COVID-19 pandemic by hotel entrepreneurs in Chiang Mai. Data was mainly collected from 154 hotels categorized into 4 types by Department of Provincial Administration and Online Travel Agency (OTA). Data analysis was conducted through data collecting week-by-week from 1st February to 31st December 2020 and the relationship of measurements and adaptation indicators was diagrammed. Moreover, this research interviewed four entrepreneurs of hotel type 2 in two areas including Nimmanahaeminda Road and the Old town.  There are three major findings: 1. The target group is different in different locations. For example, the consumer focus group of hotels located in Nimmanahaeminda Road is mainly Thai guests. Its average price trend is positive. 2. The opening and closure of each location reflects adaptation strategies. For example, hotel type 4 located in the Old Town was closed approximately 63 days. 3. Adapting strategies of Chiang Mai's hotel entrepreneurs can be applied in the short-run; however, in the long-run, GPP and GDP can be driven by international travel demand.

Authors:   , Saengtabtim Kumpol
Published: April 2023

Coronavirus pandemic or COVID-19 pandemic is considered to be one of the most severe disasters that affect both lives and economics to all the countries around the world. Health Emergency and Disaster Risk Management Framework or HEALTH-EDRM framework is the disaster management framework established in late 2019. One objective of this framework is to reduce the impact of the disaster that affects the lives of the people. Risk communication which is considered as the main function of this framework is also the main key for reducing the amount of affecting people. In this research, the analysis of the effectiveness of the HEALTH-EDRM framework will be defined based on the amount of the COVID-19 affected, death, and the ratio of death and affected cases in Asia Oceania. The paired t-test analysis will be used to compare the effectiveness for dealing with the COVID-19 situation in the aspect of the member of the framework and the economic situation. Furthermore, the Twitter microblogging platform will be defined as whether it can be used for risk communication function in terms of nearly real-time and reliable property. The analysis will be performed by comparing the content between the WHO’s situation report and the Twitter data from 21 January 2020 until 16 August 2020 based on daily, weekly, monthly, and quarterly based. The Latent Dirichlet Allocation (LDA) and Cosine Similarity will be used as the tools for generating topics and comparing the similarity. The results of both analyses show that even though the HEALTH-EDRM framework did not perform well to help their members for dealing with the COVID-19 situation, this framework can perform well for helping the least developed countries. In addition, Twitter is proved to be useful as a near real-time and reliable source of information.

Peran fear of missing out (FOMO) dan penggunaan media sosial terhadap artikulasi identitas keislaman pada kalangan milennial muslim yang mengikuti tren hijrah di Instagram
Authors: Husna Sabiqotul
Published: April 2023

Based on study of 177 millennial Muslims in Indonesia who actively engaged in the hijrah movement through their Instagram, this study aims to reveal the relationship between FOMO and problematic use of social media, with the articulation of Islamic identity. The measuring instruments used in this research were the adaptation of the FOMO scale, the ad­aptation of social media disorder scale and the articulation of Islamic identity on Instagram scale. The results of the analysis using multiple regression showed that simultaneously FOMO and problematic use of social media predicted the articulation of Islamic identity with a simultaneous effective contribution of 40.6% (36.7% the contribution of social media use & 3.9% the contribution of FOMO). We also found that FOMO independently had no correlation with the articulation of Islamic identity, but the use of problematic social media proved to have a significant correlation with the articulation of Islamic identity. These findings may serve as a basis for further research related to the theme of religious identity articulation in social media and the formulation of interventions for excessive use of social media.

Oriented cell divisions balance self-renewal and differentiation in stratified epithelia such as the skin epidermis. During peak epidermal stratification, the distribution of division angles among basal keratinocyte progenitors is bimodal, with planar and perpendicular divisions driving symmetric and asymmetric daughter cell fates, respectively. An apically restricted, evolutionarily conserved spindle orientation complex that includes the scaffolding protein LGN/Pins/Gpsm2 plays a central role in promoting perpendicular divisions and stratification, but why only a subset of cell polarize LGN is not known. Here, we demonstrate that the LGN paralog, AGS3/Gpsm1, is a novel negative regulator of LGN and inhibits perpendicular divisions. Static and ex vivo live imaging reveal that AGS3 overexpression displaces LGN from the apical cortex and increases planar orientations, while AGS3 loss prolongs cortical LGN localization and leads to a perpendicular orientation bias. Genetic epistasis experiments in double mutants confirm that AGS3 operates through LGN. Finally, clonal lineage tracing shows that LGN and AGS3 promote asymmetric and symmetric fates, respectively, while also influencing differentiation through delamination. Collectively, these studies shed new light on how spindle orientation influences epidermal stratification.
Coping with cultural dissonance in study abroad: affective reactions and intercultural development
Authors:   Departamento de Filología Inglesa, Facultad de Humanidades y Ciencias de la Educación, Universidad de Jaén, Méndez García María del Carmen
Published: April 2023

This paper investigates feelings and emotions in intercultural development through an analysis of students’ journals. It looks into the affective reactions to life in Spain and how these relate to the intercultural development of a cohort of 26 American students participating in a calendar year study abroad programme (SAP) in a Spanish university, a pertinent study given that Spain, which hosts 9,5% of total American students abroad, has become the third preferred destination of American university students (Institute of International Education, 2019). Although the literature on cultural dissonance highlights the prevalence of feelings of distress when sojourners are removed from their social support systems, findings divulge a myriad of feelings classified into 9 areas that show a balance between uncertainty and stress of study abroad (SA), and excitement and feelings of well-being. Departing from affective reactions, analysis has likewise been conducted on how students come to terms with a different reality. Data evince that understanding new meanings and symbols is done through a comparative/contrastive problematising orientation through which SA is presented as challenge rather than as threat. The paper concludes that SA and reflection upon it contribute to reassess and shift frames of reference, influencing intercultural development and personal growth.
A review on grammatical gender acquisition in monolingual Spanish-speaking children
Authors:   Department of Psychology, Faculty of Educational Sciences, University of A Coruña, Ogneva Anastasiia
Published: April 2023

Acquisition of grammatical gender has been well addressed in psycholinguistic research with Spanish monolingual typically developing (TD) children but less with children diagnosed with Developmental Language Disorder (DLD). The present article reviews linguistic and psycholinguistic studies on grammatical gender acquisition from different methodologies across monolingual Spanish-speaking children with typical language development and children diagnosed with DLD. Specifically, we explore how typically developing and DLD children assign grammatical gender and establish gender agreement. We discuss the implication of the findings for the design of the future research on gender acquisition.
Influencia de la Espiritualidad y Religiosidad sobre la Felicidad en Adultos Mayores
Authors:   Universidad de Talca (Chile), Moyano-Díaz Emilio , Saldías-Ortega Felipe ,   Universidad de Talca
Published: April 2023

Existe un creciente cuerpo de investigación acerca de cómo la espiritualidad y religiosidad afectan la vida de las personas. Hay modelos para examinarlo en personas con cáncer, depresión o anorexia, siendo menos frecuente su modelación en población general o sana y, particularmente, en adultos mayores (AM). El objetivo del estudio fue identificar si la espiritualidad y la religiosidad predicen la felicidad de los AM. La muestra fue no probabilística, por conveniencia y disponibilidad, mediante el método de bola de nieve. Fueron 206 participantes (170 mujeres, 36 hombres) de Ñuble, una región del centro sur de Chile, de más de 60 años de edad (M = 70 años, DE = 6,86), quienes respondieron un cuestionario que incluyó datos sociodemográficos, la versión colombiana del Cuestionario de Espiritualidad de Parsian y Dunning, la versión española de la Escala de Orientación Religiosa "Age Universal" I-E-12 de Allport y Ross y la Escala de Felicidad para Adultos (EFPA) (Moyano-Díaz et al., 2018). Se observa que los AM presentan niveles medios de religiosidad, altos en espiritualidad y correlaciones significativas entre estas. Se prueban 3 modelos a través de regresión lineales con mediación para explicar felicidad, utilizando la religiosidad como variable predictora y la espiritualidad como mediadora. Se concluye que espiritualidad y religiosidad predicen la felicidad en AM, entre otros resultados.
Exploring the Relation Between Metacognition, Gender, and Personality in Colombian University Students
Authors:   Georgia Southern University, Gutierrez de Blume Antonio P. , Montoya Diana ,   Universidad de Caldas
Published: April 2023

In the present study, the relationship between objective and subjective measures of metacognition, personality traits of the Big Five (extraversion, agreeableness, conscientiousness, neuroticism, and openness) and gender were examined. A convenience sample of 352 university students completed the Metacognitive Awareness Inventory, the Adjectives to Evaluate Personality instrument, and completed 3 domain-specific tests (vocabulary, probabilities, paper folding) along with confidence in performance judgments for each item on these tests. Through a combination of descriptive statistics, zero-order bivariate correlations, simultaneous multiple regression, and a multivariate analysis of covariance, findings indicate that objective and subjective measures of metacognition are weakly related and that subjective measures of metacognition were more strongly related to personality traits. Conscientiousness and openness were the only personality traits that positively predicted metacognition. Gender affected both subjective and objective measures of metacognition, even after controlling for university type (private, public) and perceptions of academic performance (high, low) such that males were more accurate and less biased in their monitoring than females only in mathematical reasoning and they reported higher awareness of their knowledge and regulation of cognition than their female counterparts. Findings support the need to better understand how personality traits and gender affect self-regulated learning skills like metacognition to improve educational practices.
La ciudad inconclusa de la CORMU : replanteamiento del ciclo de vida del conjunto Mapocho-Bulnes
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Herrera Arévalo Simón
Published: April 2023

En Chile, entre 1965 y 1976, se desarrollaron diversos proyectos emblemáticos de vivienda colectiva como parte de la renovación urbana del país. A través del análisis de conjuntos habitacionales de la CORMU construidos en el país y de la comprensión de sus tipologías, desarrollo temporal y estrategias de proyecto. La investigación busca entender las operaciones comunes de la Corporación tanto en sus estrategias como en la utlización de piezas (tipologías) y la aplicación de estas en la ciudad ya consolidada. Cincuenta años después se vuelve a analizar y replantear el proyecto de la Corporación y se proponen nuevas posibilidades de densificación insertando piezas nuevas de distintas escalas, funciones y densidades en un contexto ya construido. El objetivo es que estas intervenciones ayuden tanto económica como arquitectónicamente a satisfacer necesidades actuales de tales conjuntos. La investigación busca validar en el día de hoy la estrategia de proyecto y construcción que existía en la época de la CORMU. Para esto se busca generar estrategias que apliquen para conjuntos habitacionales contemporáneos, teniendo como casos principales de estudio los proyectos que aparecen en el folleto escrito por la Corporación en el año 1968 y el conjunto habitacional Mapocho-Bulnes.
La reconversión de suelos centrales como oportunidad de equidad urbana : una estrategia metropolitana de movilidad sustentable y equipamiento accesible : la sustitución de autopistas urbanas por corredores públicos multimodales
Authors:   ,   Pontificia Universidad Católica de Chile. Escuela de Arquitectura, Montjoy Saravia Valeria
Published: April 2023

Ante la potente desigualdad socio-territorial que enfrenta Santiago, la infraestructura vial ha sido incapaz de equiparar el acceso a funciones urbanas esenciales, traduciéndose en autopistas que no solo revelan patrones de inequidad, sino que los acrecientan. El protagonismo del automóvil en el modelo de movilidad es evidente; así lo demuestra la cantidad de planes e inversiones destinados a la construcción de nuevas autopistas. De esta manera, al priorizar siempre el tránsito expedito del transporte privado, el modelo favorece una conectividad metropolitana, pero en detrimento de la calidad urbana de barrios. Por lo tanto, la periferia habitacional, el sector más vulnerable y segregado de la ciudad, debe sufrir las consecuencias de una infraestructura hermética que fragmenta y amenaza sus relaciones barriales. La investigación plantea que la manera de reconvertir barrios, detonar desarrollo urbano y generar equidad en la periferia es mediante una movilidad pública y sustentable capaz de revertir las desigualdades generadas por las autopistas. Para ello, detectando la cantidad de superficie ocupada por Vespucio y las vías a su interior, se abre la posibilidad de implementar una estrategia de movilidad en suelos de primer nivel. Así, la reconversión de suelos centrales surge como una oportunidad no solo de brindar accesibilidad, sino que también de proveer a barrios periféricos de espacio público, vivienda y equipamiento de calidad. La propuesta se aborda desde dos escalas: una estrategia metropolitana y su aplicación en una pieza urbana.
Liderazgo directivo para la retención de docentes de excelencia en un liceo técnico profesional de la comuna de Santiago : un estudio de caso
Authors:   ,   Pontificia Universidad Católica de Chile. Facultad de Educación, Ortíz Reyes Felipe
Published: April 2023

Distintos estudios han reconocido la importancia de la calidad de los docentes en el aprendizaje de sus alumnos, sin embargo, el sistema educativo chileno, tiende a agrupar a los docentes de excelencia en colegios particulares, dejando a escuelas con altos índices de vulnerabilidad con maestros de menor rendimiento. Esta situación perjudica a los estudiantes con mayores problemas socioeconómicos, pues en investigaciones se demuestra que la calidad de los profesores afecta directamente en el proceso de enseñanza-aprendizaje. El presente estudio tiene como objetivo caracterizar las estrategias de retención de docentes de excelencia percibidas por el director de un liceo técnico profesional de la comuna de Santiago. La naturaleza de este estudio es cualitativa y la metodología utilizada es un estudio de caso único, para la cual, se realizaron 10 entrevistas a distintos miembros de la comunidad educativa, donde, además, se revisaron los documentos oficiales de la institución. Los principales resultados nos muestran que la principal estrategia de retención presente en este liceo es generar un buen clima organizacional, que está por sobre el factor económico y el orden en la gestión institucional.
