Published: June 2023

The mammalian pulmonary vasculature consists of functionally and morphologically heterogeneous compartments. When comparing sets of lungs, for example, in disease models or therapeutic interventions, local changes may be masked by the overall heterogeneity of the organ structure. Therefore, alterations taking place only in a sub‐compartment may not be detectable by global analysis. In the monopodial lung, the characterization of distinct vessel groups is difficult, due to the asymmetrical branching pattern. In this pilot study, a previously established method to classify segments of the monopodial pulmonary arterial tree into homogeneous groups was employed. To test its suitability for experimental settings, the method was applied to a hyperoxia (HYX, ≥95% oxygen) rabbit model of bronchopulmonary dysplasia and a normoxic control group (NOX, 21% oxygen). The method allowed the identification of morphological differences between the HYX and the NOX groups. Globally visible differences in lumen diameter were pinpointed to specific lung regions. Furthermore, local changes of wall dimension and cell layers in single compartments, that would not have been identifiable in an unfocused analysis of the whole dataset, were found. In conclusion, the described method achieves a higher precision in morphological studies of lung disease models, compared to a common, global analysis approach.

Coral reefs are one of the most biodiverse marine ecosystems. Diverse microbes are associated with corals, including zooxanthellae, protists, prokaryotes, and viruses. This study aimed to investigate the genetic diversity of the culturable fungi associated with scleractinian corals in the Gulf of Thailand. Ribosomal DNA sequence analysis and morphological analysis of 130 fungal isolates revealed a high diversity of fungal phylotypes from three coral species: Pavona decussata, Pocillopora damicornis and Porites lutea. Ascomycota was the most abundant fungal phylum. The predominant orders included Eurotiales, Cladosporiales, Hypocreales, Mycosphaerellales, and Diaporthales. There were eight orders of the Basidiomycota dominated by Polyporales, Hymenochaetales, Agaricales, and Wallemiales. A principal component analysis was performed to compare abundance and correlation between the fungal communities, sampling locations and coral species. The results showed that the dissimilarity of fungal communities corresponded to geographic localities. On the other hand, there was a considerable overlap between the fungal communities of different coral species. The results from this research provide information on the diversity and ecology of the fungal communities associated with scleractinian corals in the Gulf of Thailand.
The context of science fiction in the pre-service teachers’ chemistry education
Authors: Vošnjak Matej , Devetak Iztok
Published: June 2023

Context-based teaching and learning has a long tradition in science, especially chemistry. Audiovisual media (movies and series) can be used to provide context, and it can help overcome many students’ negative attitudes toward real science. An example of audiovisual media in which a science context can be presented is science fiction (abbreviated Sci-Fi). The purpose of this study was to investigate how the Sci-Fi context influences pre-service teachers’ attitudes and perceptions regarding the use of Sci-Fi for teaching and learning science, with a focus on chemistry, as a result of a 15-week novel elective Sci-Fi course for pre-service teachers. The main instruments used were online questionnaires, a final exam, and a rubric-based presentation evaluation form. The results of our study show that the majority of pre-service teachers consider the Sci-Fi context to be a very interesting context for science education, especially chemistry, and a useful tool for promoting students’ interest in science. Students believe that it is important to incorporate the Sci-Fi context into chemistry instruction at all levels. Our results suggest that the Sci-Fi context is useful to students as an alternative learning method that can be used to improve student learning outcomes.
The Subordination of Shareholder and Intragroup Loans in Italy. Shifting Perspective in the Wake of the Covid-19 Emergency Legislation
Authors: Borselli Angelo
Published: June 2023

Amidst the COVID-19 outbreak, Italy as well as a number of other European states, including Austria, Germany and Spain, enacted emergency legislation suspending subordination of shareholders and intragroup loans in order to help companies stay afloat. While this measure was clearly prompted by extraordinary circumstances, it should be noted, however, that unlike jurisdictions which adopt automatic subordination, such as Germany and Spain, or where subordination is also based on quantitative criteria, such as Austria, subordination in Italy is based on flexible standards that may not strictly call for an emergency suspension. The COVID-19-related suspension of subordination provides the momentum for reassessing the scope of application of the subordination of shareholder and intragroup loans under Italian law. Although substantially unexplored in the international legal literature, subordination was introduced in Italy in 2003 and has now been applied for nearly twenty years. The system is quite sophisticated and also recognizes a variety of restructuring exemptions allowing priority to the loans. This paper examines subordination of shareholder and intragroup loans under Italian law, seeking to establish a workable construction of the standards of the excessive imbalance between debt and equity and of the reasonableness of a capital contribution on which the application of the remedy is predicated. Building also on relevant economic studies, the paper argues that the Italian subordination system has the potential to distinguish between desirable and undesirable shareholder and intragroup loans based on whether the loan is intended to finance positive net present value projects, restricting the latter while not deterring the former, so as to guarantee the goal of increasing the expected total value of the company and producing better satisfaction of creditors’ claims.

Development and application of an evidence-based directed acyclic graph to evaluate the associations between metal mixtures and cardiometabolic outcomes
Authors: Riseberg Emily , Melamed Rachel D. , James Katherine A. , Alderete Tanya L. , Corlin Laura
Published: June 2023

Objectives

Specifying causal models to assess relationships among metal mixtures and cardiometabolic outcomes requires evidence-based models of the causal structures; however, such models have not been previously published. The objective of this study was to develop and evaluate a directed acyclic graph (DAG) diagraming metal mixture exposure and cardiometabolic outcomes.

Methods

We conducted a literature search to develop the DAG of metal mixtures and cardiometabolic outcomes. To evaluate consistency of the DAG, we tested the suggested conditional independence statements using linear and logistic regression analyses with data from the San Luis Valley Diabetes Study (SLVDS; n=1795). We calculated the proportion of statements supported by the data and compared this to the proportion of conditional independence statements supported by 1,000 DAGs with the same structure but randomly permuted nodes. Next, we used our DAG to identify minimally sufficient adjustment sets needed to estimate the association between metal mixtures and cardiometabolic outcomes (i.e., cardiovascular disease, fasting glucose, and systolic blood pressure). We applied them to the SLVDS using Bayesian kernel machine regression, linear mixed effects, and Cox proportional hazards models.

Results

From the 42 articles included in the review, we developed an evidence-based DAG with 74 testable conditional independence statements (43 % supported by SLVDS data). We observed evidence for an association between As and Mn and fasting glucose.

Conclusions

We developed, tested, and applied an evidence-based approach to analyze associations between metal mixtures and cardiometabolic health.

Successful treatment of hypercalcemia in a Chinese patient with a novel homozygous mutation in the CYP24A1 gene using zoledronic acid: a case report
Authors: Zheng Zhichao , Wu Yujie , Wu Huiping , Jin Jiahui , Luo Yue , Cao Shunshun , Shan Xiaoou
Published: June 2023

Objectives

To emphasize the significance of genetic mutations in idiopathic infantile hypercalcemia and the potential therapeutic effectiveness of zoledronic acid in managing hypercalcemia attributed to gene mutations.

Case presentation

A 1-year-old female infant was referred to our hospital. The patient developed hypercalcemia despite no vitamin D prophylaxis or intake. In the acute phase, conventional calcium-lowering treatments showed limited efficacy, while the administration of zoledronic acid demonstrated effectiveness in controlling hypercalcemia. Subsequently the patient maintained normal calcium levels via a low-calcium diet and avoiding vitamin D intake. Genetic testing confirmed a homozygous mutation (c.476G>C) in the CYP24A1 gene.

Conclusions

Family screening and genetic counseling are crucial for early detection and prevention of hypercalcemia. This case emphasizes the importance of genetic mutations in disease development and the potential therapeutic efficacy of zoledronic acid in managing hypercalcemia attributed to gene mutations.
A Bayesian analysis of the time through the order penalty in baseball
Authors: Brill Ryan S. , Deshpande Sameer K. , Wyner Abraham J.
Published: June 2023

As a baseball game progresses, batters appear to perform better the more times they face a particular pitcher. The apparent drop-off in pitcher performance from one time through the order to the next, known as the Time Through the Order Penalty (TTOP), is often attributed to within-game batter learning. Although the TTOP has largely been accepted within baseball and influences many managers’ in-game decision making, we argue that existing approaches of estimating the size of the TTOP cannot disentangle continuous evolution in pitcher performance over the course of the game from discontinuities between successive times through the order. Using a Bayesian multinomial regression model, we find that, after adjusting for confounders like batter and pitcher quality, handedness, and home field advantage, there is little evidence of strong discontinuity in pitcher performance between times through the order. Our analysis suggests that the start of the third time through the order should not be viewed as a special cutoff point in deciding whether to pull a starting pitcher.
XRD analysis determined crystal cage occupying number n of carbon anion substituted mayenite-type cage compound C12A7: nC
Authors: Ji Cong , Gu Fan
Published: June 2023

In this study, a series of samples of C12A7 derivative was prepared by high temperature sintering in a sealed graphite crucible. The theoretical model of C12A7 derivatives with different carbon occupation numbers was established. The X-ray diffraction (XRD) theoretical calculation was carried out. The conjecture was verified to a certain extent through the comparison of the theoretical calculation of XRD with the experimental results. According to the calculation results, it was found that the XRD patterns of C12A7 and its derivatives changed regularly with the change in the occupation number in the crystal cage. Under the condition that the types of vacancy atoms remained unchanged, the more vacancy atoms occupied in C12A7 crystal, the higher the peak at 2θ = 33.35° in the diffraction pattern. It was also found that the higher the atomic number of vacancy atoms in C12A7 crystal, the higher the peak at 2θ = 33.35° in the diffraction pattern. The carbon occupation number of samples at different experimental temperatures was deduced. The results showed that the carbon occupancy of the samples prepared at 990, 1,353 and 1,680°C were 11, 4 and 8, respectively.
Experimental analysis of performance and tip dynamic pressure in a compressor cascade with high-speed moving endwall
Authors: Xia Kailong , Deng Hefang , Lu Shaopeng , Teng Jinfang , Qiang Xiaoqing , Zhu Mingmin
Published: June 2023

This study measured the aerodynamic performance and dynamic pressure signals of a compressor cascade platform with high-speed rotating endwall. Instead of translational movement, the endwall features an innovative large rotating disk. Measurements were conducted on a controlled diffusion airfoil (CDA) under different conditions: tip clearances (3 mm and 2.5 mm), inlet incidences (+6° and −6°), and stationary or high-speed rotating states at 0.5 Ma inflow. The results reveal that endwall movement amplifies circumferential leakage losses, increases kinetic energy, deviates the leakage flow path, and reduces total pressure loss in the leakage core region. Dynamic pressure results reveal greater unsteadiness in the tip region under positive incidence conditions and with larger clearances. Characteristic frequency ranges (8000 Hz for system vibration and 150∼200 Hz for leakage flow development) are identified. Further experimental measurements and high-precision simulations are needed the determine the matching relationship between complex flow behaviour in the blade tip region and characteristic frequency.

The structure of 1 consists of molecular [K(C12H24O6)B5O6(OH)4]0 complexes, common for crown ether complexes but yet not among borates, with a very rare monodentate coordination of the common pentaborate anion(1-). The molecular complexes are linked into weak chains via hydrogen bonding to outer-sphere water molecules. Hirshfeld surfaces analysis and complexity measurement of 1 were performed. Perspectives of borate structures containing crown ether complexes as templates are briefly outlined.

Does Fiscal Policy Matter? A Study on Economic Crises in Indonesia
Authors: Prasasti Sri Rejeki , Ekananda Mahjus
Published: June 2023

Fiscal policy is one of the instruments used by the government in dealing with economic crises. The recent COVID-19 pandemic crisis has different characteristics from the previous ones in  Indonesia. Hence, the fiscal policy needed is also different. Therefore, this study aims to know the role of fiscal policy shocks in affecting some macroeconomic indicators, including GDP, inflation, and interest rate, in Indonesia and investigate its differences within two periods: Period I (1993Q1-2018Q4), which includes the Asian Financial Crisis and the Global Financial Crisis, and Period II (2019M1-2021M12), which include the COVID-19 Pandemic crisis. This study employs the Structural Vector Autoregression (SVAR) model, using institutional information of the government budget system as restrictions. This study concludes that: 1) shocks in fiscal policies significantly affect GDP in both periods; 2) the dynamic movement of GDP is more influenced by government spending than government revenue; 3) fiscal policy, especially revenue, has greater influences on inflation during the COVID-19 Pandemic; 4) fiscal policy has a minor role in affecting the interest rate.

Published: June 2023

This study discusses the economic performance of the Danone-AQUA circular in maximizing the value of plastic waste in terms of proper plastic waste sorting management or circular packaging, water and carbon circular and business circular.  Economy Circular was proposed because of its increasing popularity in the midst of the world's problem with global carbon reduction. The selection of Danone-AQUA Economy Circular is the right way to find out how significant the efforts of non-government organizations are in creating a sustainable economy and environment. This study analyses the performance of Danone-AQUA's circular economy through six circular economy dimensions in managing and maximizing the value of plastic waste in a positive way to reduce the impact of plastic waste workers in Indonesia.  This study uses a systematic literature review and adopts a research design to extract research data. The data comes from interviews with Packaging Circularity Senior Manager at Danone, Indonesia. The economic circular performance of Danone-AQUA in maximizing the value of plastic waste contributes to the reduction of plastic bottle packaging waste. The study proves that the impact of circular economy performance in maximizing the value of plastic waste is positive because it increases the function of plastic bottle packaging waste and has value again and reduces the negative impact of plastic waste on the environment. In achieving the performance of maximizing the value of plastic waste, Danone-AQUA applies six circular economy dimensions which are concentrated on three policies, namely packaging circular, water and carbon circular and business circular.

Authors: Genç Rabia , Bilgin Turna Gülçin
Published: June 2023

This study aims to investigate the relationship between consumers' social media addiction (SMA) levels and their online purchasing intentions (OPI) while examining the mediating role of attitudes towards online advertisements (ATOA) in this relationship. Additionally, the study aims to explore whether the demographic characteristics of consumers influence their levels of SMA, ATOA, and OPI. An online questionnaire consisting of the ATOA, SMA, OPI scales and demographic characteristics was shared with 402 participants using convenience sampling. Confirmatory factor analysis and structural equation modelling were applied to the data. T-tests, ANOVA, Levene, Tukey, and Tamhane T2 tests were used for difference analysis. According to the results, social media addiction positively affects the attitude towards online advertising and purchase intention. There is a partial mediating effect of the attitude towards online advertising in the effect of social media addiction on online purchase intention. Discriminant analysis results show that social media addiction is higher among single students between 18 and 25. While the attitude of young and single students towards online advertisements is more positive, the attitude towards online advertisements is more negative in consumers aged 36 and over compared to other consumers. Online purchase intention is higher in female consumers with a bachelor's degree or higher education level and lower in consumers over 36 years of age with a low-income level. Thus, it is recommended that practitioners focus on this target group in online advertising.
Equilibrium, kinetic, and thermodynamic studies of the biosorption of Mn(II) ions from aqueous solution by raw and acid-treated corncob biomass
Authors: Adeogun Abideen Idowu , Ofudje Andrew E. , Idowu Mopelola , Kareem Sarafadeen O.
Published: June 2023

Biosorption was carried out in a batch process to test the suitability of corncob for the removal of manganese ion (Mn(II)) from aqueous solution. The amount of metal ions removed from solution depended on the metal ion-substrate contact time, ion concentration, temperature, and pH. The adsorption capacity of the biosorbent from corncob was also enhanced by treatment with acid. Kinetic modeling of the data obtained from the study showed that the biosorption of Mn(II) ions by the untreated and acid-treated corncob followed the Largergren pseudo-first order model. The adsorption capacity of the raw biomass was found to be 6.54 mg/g, while acid-treated biomass showed an adsorption capacity of 7.87 mg/g. The data obtained from this study fitted well with the Freundlich and Langmuir adsorption isotherms.

Authors: Peng Pengjie , Zhou Xiaofan , Ma Jinxia
Published: June 2023

With the rapid development of the packaging industry, the requirements for physical properties of corrugated paperboard tend to become higher and higher, especially for the strength properties. A water glass-starch compound system was employed as a surface sizing agent to improve the strength of linerboard in this work. The viscosity of water glass-starch compound system, and its impacts on ring-crush strength and bursting strength of linerboard were evaluated. Cobb value and contact angle were used to characterize the waterproof performance of paper after surface sizing. Compared with conventional surface sizing agents, water glass-starch compound system overcame the defects of low coating weight and inadequate stiffness of the sizing layer, allowing ring-crush strength and bursting strength of linerboard to increase by 91% and 50%, respectively. Additionally, the compound system had higher solids content, low viscosity, and good film-forming ability, which will bring a lot of convenience to production.

Authors: Liu Shanshan , Fang Guigan , Wang Qiang , Deng Yongjun , Han Shanming
Published: June 2023

Kinetic modeling of enzymolysis of pulp fiber waste pretreated by a wet oxidation process was studied. First, a wet oxidation pretreatment of fiber waste was carried out. It was found that hemicellulose were removed efficiently, yielding material with a pentosan content of 4% (based on the o.d. biomass). A statistical kinetic model was developed based on the experimental results of the enzymatic hydrolysis of wet oxidation pretreated material. The model can be described as follows: RSY (reducing sugar yield)=12.48×C0.4261×(1-e-0.2021t) ×100%, an equation that can be used to predict the reducing sugar yield in an enzymolysis process. The RSY by enzymatic loading of 35FPU/g achieved almost the highest yield after 48 h, and there was no significant improvement with further extension of the enzymolysis time. The modeling was validated within the enzymatic loading range of 15 to 35FPU/g and provided a satisfactory interpretation of the experimental data.
The impacts of lignin coverage, relative bonded area, and fiber properties on sheet strength
Authors: Wang Baoyu , Li Rong , He Beihai , Li Junrong
Published: June 2023

In order to determine the quantitative relationship between sheet strength and lignin coverage at the fiber surface, CTMP was blended with softwood bleached kraft pulp (BKP), refined softwood BKP, and hardwood BKP. The morphology of the fibers, fibers properties, fiber surface components and relative bonded area of sheets were investigated. Multi-linear regression equations of tensile strength index and internal bond strength were established. The results indicated that unbleached aspen CTMP fiber surfaces were covered by granules of lignin, and BKP fiber surfaces were predominated covered by microfibrils. Fiber properties have a significant impact on tensile strength index. RBA had a greater impact on IBS than lignin coverage. For the pulp samples tested, a 1% increase in lignin coverage at fiber surfaces would lead to a 0.48N·m/g decrease in tensile strength index and 5.32×10-3 J/m2 decrease in internal bond strength.
Continuous seam explosion of wheat straw by high pressure mechanical refining system to produce sugars for bioconversion
Authors: Fang Haixia , Deng James , Zhang Xiao
Published: June 2023

This study demonstrated the use of a pressurized mechanical refining system for the continuous steam explosion pretreatment of wheat straw. Wheat straw was first impregnated with either dilute acid (0.5% sulfuric acid) or water and then steam exploded in an Andritz pressurized refiner. The effect of a range of pretreatment conditions, including refining retention time and steam pressure/temperature on the resulting substrate composition and hydrolysability as well as overall sugars yield was investigated. For autohydrolysis, the optimum conditions, 198 oC/6 min gave an enzymatic hydrolysis yield of 93.3% and an overall glucose yield of 85.8%, while 198 oC/4 min gave an enzymatic hydrolysis yield of 88.7% and overall glucose yield of 88.4%. Longer retention time increased the enzymatic hydrolysability but reduced the overall glucose yield owing to the degradation reaction during pretreatment. For acid pretreatment, the most favourable condition for enzymatic hydrolysis and overall glucose yield coincided at 178 oC /6 min.
Non-isothermal crystallization kinetics of Kevlar fiber-reinforced wood flour/HDPE composites

Published: June 2023

Non-isothermal crystallization of neat high density polyethylene (HDPE), wood flour (WF)/HDPE composite (WPC), virgin Kevlar fiber (KF) reinforced WPC (KFWPC), and grafted Kevlar fiber (GKF) reinforced WPC (GKFWPC) was investigated by means of differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Several theoretical models were applied to describe the process of non-isothermal crystallization. The results showed that the Avrami analysis modified by Jeziorny and a method developed by Mo and coworkers successfully described the non-isothermal crystallization behavior of HDPE and composites. The Ozawa analysis, however, failed to provide an adequate description of non-isothermal crystallization. The values of crystallization peak temperature (Tp), half-time of crystallization (t1/2), and kinetic parameters KJ and F(T) showed that the crystallizability followed the order: FKWPC > GKFWPC > HDPE > WPC. The effective activation energy for non-isothermal crystallization of HDPE and composites based on both Kissinger and Friedmen methods was evaluated. WAXD indicated that the crystalline thickness perpendicular to the reflection plane (Lhkl) increased with the addition of KF. The results demonstrated that KF and GKF can act as nucleating agents and increase the crystallization rate of HDPE. Compared with GKF, KF is a more effective nucleating agent for HDPE, and wood flour cannot act as a nucleating agent for HDPE.
A Grow Together Project: Performance Evaluation of Improvised Organic Fertilizers on the Yield of Cash Crops and its Economic Contribution to Agriculture Graduates in Tawi-Tawi Province, Philippines
Authors: Puhagan Edwin M
Published: June 2023

This study considers improvised organic fertilizers as one of the bioremediation therapies to restore soil fertility and the ecological stability of the farming environment. This used four homemade materials and leftovers to create improvised organic fertilizers. Banana peels, papaya peels, leaves, fish remains, and sea urchin pines are common food wastes that typically have no further use after the food has been devoured. Farmers could use these materials in a bioremediation process that supports the farming environment's ecological and economic stability. This study provides feedback on the significance of homemade organic fertilizer as it improves farmers' economic and environmental contributions. The parameters of this study were the yields of these four crops and the farmer's income. In this study, four different crops—peanut, bell pepper, string bean, and corn—were subjected to four different concentrations of improvised organic fertilizers, including: for the peanut, a concentrated mixture of ripe banana peels and papaya extract; for the bell pepper, a concentrated mixture of triturated sea urchin spines and basil extract; for the corn, a concentrated mixture of algae and wild basil extract; and for the string bean, a The data was analyzed using a Randomized Complete Block Design (RCBD), which produced highly good yield results for these crops and thus boosted the local farmers' income. The results were as follows: 1) Peanuts treated with 1500ml improvised organic fertilizers yielded 3.06 kilograms with a total mean score of 3.59abc; 2) Bell peppers treated with 1500ml improvised organic fertilizers yielded 15.9 kilograms with a total mean score of 5.30; and 3) corn treated with 1500ml improvised organic fertilizers yielded 5.30 kilograms with a total mean score of 5.30. The farmers' income was implied by the investment's return on these four crops. According to the study, income grows when yield rises, and selling volume is high.
Forecasting Using Point-valued Time Series and Fuzzy-valued Time Series Models
Authors: Mansor Rosnalini , Zaini Bahtiar Jamili
Published: June 2023

The point-valued time series (PTS) is simply about one value in each time or period of the data, but when the data have two values at each time, the suitable time series is called the interval-valued time series (ITS). An example of ITS is the daily close and open stock prices. If the time series data are of typed linguistic data, for example, “low increase”, “medium increase” and “high increase”, the time series data are called a fuzzy-valued time series or being well-known as fuzzy time series (FTS). The aim of this study is to compare the PTS and FTS models for forecasting stock prices in the stock market. The stock market is one of the essential investments in the economy. The movement of stock price can be leading or declining which respectively expands or contracts a country’s economy. The movement may also represent the scenario or event happening in a company. Therefore, forecasting stock price movement is highly important since it will assist investors and sellers to make planning in their investment’s decision. Therefore, the objectives of this study are to identify the best forecasting models in point-valued time series (PTS) and fuzzy time series (FTS) based on forecasting measurement error. Eight stock price forecasting models consisting of four models from PTS and four models from FTS. Meanwhile, four forecasting measurement errors were discussed in the analysis as a criterion for choosing the best forecasting model. A set of daily historical data from the Bursa Malaysia website was used as a basis for analysis. The finding shows the simple exponential smoothing model is the best PTS model. In the meantime, the Cheng model based on Sturges’ rule is the best FTS model. However, among these two types of models, the Cheng model is found to be the best model with forecasting measurement errors of 0.0001 (MSFE), 0.0108 (RMSFE) and 1.1918 (MAPFE). The results reveal that besides the PTS model, the FTS model is an alternative model to forecast stock market movement. Moreover, these FTS and PTS models can also be applied to solving other forecasting problems.

Published: June 2023

This study was done to ascertain how Public Secondary Schools in Tawi-Tawi will implement Intensive School-Based Instructional Supervision. School principals and teachers who participated in the study as respondents were surveyed using the descriptive-quantitative technique of research. The data were statistically processed using multiple regression analysis, weighted mean, and standard deviation. The results showed that the principals of each school had adopted intensive school-based instructional supervision in terms of help and support, creative strategy, monitoring, and evaluation. Similar to how the students did in terms of academic achievement, instruction delivery, and classroom management, the teachers also demonstrated successful teaching performance. The study also showed that principals' intensive school-based instructional supervision in terms of assistance and support, innovative strategy, and monitoring and evaluation significantly impacted academic teaching performance, academic achievements, instruction, and classroom management. In addition, the principals' assistance and support, innovative strategy, and monitoring and evaluation are good predictors of teacher performance. Additionally, but not in terms of assistance and support, the principals' creative approach, monitoring, and evaluation are excellent predictors of teachers' classroom management.

The research aimed to investigate mushroom cultivation materials made from rice straw, maize, and giant mimosa to replace sawdust. It was discovered that the capacity of fibers to grow has been more valuable. The method that combines a 1:1:1 ratio of the sawdust, rice straw, and giant mimosa will produce the highest mycelium. The 100% maize seed material will have relatively low fiber mycelium. However, there was a statistically significant in mushroom growth at the 95% reliability level. It was found that the process consisting of 100% rice straw cultivation material had the highest number of blossoms on average 13.66 blossoms, while the method with the lowest average number of blossoms per bag was the sawdust combined with giant mimosa which had 7.33 blossoms on average. The blooms ranged in width from 6.83 - 7.53 cm, while the mushroom's peduncle length ranged from 5.83 - 6.84 cm. When the biological efficiency (B.E.) was calculated, it was found that the sawdust: rice straw: maize: giant mimosa ratio of 1:2:1:1 yielded the highest value of 68.48 %, followed by the Para rubber sawdust: rice straw: maize: giant mimosa. The ratio of 2:1:1:1 was 68.22%, and the seed material was 100% sawdust. The biological efficiency of the ecosystem was 66.39%.

This study aims to investigate the dominant issues of patriarchy in Indonesian folktales by utilizing Derrida's deconstruction concept. Five folktales chosen as objects of the study, and data collection did by document analysis. The findings then analyzed qualitatively by applying Derrida’ deconstruction concept as proposed by Barry that involves verbal, textual, and linguistic analysis to investigate the existence of patriarchy issues in the objects of the study. The results show that dominant patriarchal issues found in the folktales describe about labeling for women, violence against women, and male domination in cultural institutions and social life. Since the transcendental aspects considered problematic regarding the development of mental, moral, emotional, intellectual, and social skills in children, further deconstruction recommended to eliminate or to minimize the taboo issues, labeling, adult’ issues, and violence against women found in the folktales. Hence, to keep the folktales interesting and meaningful for todays’ children as the target audience of folktales, deconstruction in the form of a simple parody is highly recommended by enriching the texts with interesting pictures or illustrations, considering the use of simple yet communicative expressions, and focusing the themes about friendship, collaboration, and adventure relevant for children.

This paper presents a proposal for a strategic management plan to optimize the maintenance system of mining companies. In the first phase of this investigation, the potential failures and their possible consequences for the machinery, the administrative area, the warehouse, and computing hardware were identified to determine the most critical components and thus propose a strategic maintenance plan that includes preventive actions for each of the areas concerned. The data for this research were collected through a bibliographic review, direct observation, surveys, and interviews. Standardized tools and techniques such as criticality analysis, the balanced scorecard, and SWOT matrices were used. The research is of a projective type, with a non-experimental field design. The action plan includes the strategies necessary to close the gap between the current state and the desired optimum level. It establishes the impact that applying the proposed improvement plan for maintenance management will have on companies in the mining sector, both in terms of productivity and competitiveness. In conclusion, for mining companies to have strategic planning for equipment and infrastructure maintenance that will allow them to improve their productivity, sustainability, and competitiveness, they must have a strategic plan developed in situ, which includes as many variables as possible, trying to cover all the common elements that will allow this strategy to be applied in mining companies both regionally and globally.

The study aimed to assess the technological competence and pedagogical content knowledge practices of Junior High School Science Teachers in Southeast Butuan District 1, Division of Butuan City. A descriptive-correlational design was used, and data were collected from 31 science teachers in the district. A survey questionnaire was administered to assess the participants' level of technological competence in terms of using ICT in teaching, as well as their level of PCK practices in terms of Subject Matter Knowledge (SMK), Instructional Representation Strategies (IRS), Instructional Objective and Context (IOC), and Evaluation of Students Learning (ESU). The Net Agreement Rating (NAR) for their responses on the different areas of TPACK was recorded and cross-tabulated. The findings of the study indicated that the participants demonstrated high levels of technological competence in using ICT in teaching and high levels of PCK practices in relation to SMK, IRS, IOC, and ESU. The study also revealed a moderate positive correlation between the level of technological competence and pedagogical content knowledge practices of the teachers. This suggests that while technological competence may contribute to the enhancement of pedagogical content knowledge practices, there are other factors that can also influence effective teaching. Based on these results, it is recommended that further research be conducted to explore the impact of technology integration on the development of pedagogical content knowledge among teachers. Additionally, identifying other factors that may influence their PCK practices would be beneficial.
