Authors: Bontinge Stenly Recky , Prasetya Agus , Kamulyan Budi
Published: November 2022

The abundant supply of greywater as domestic waste becomes an opportunity for further processing and can be reused as water (reuse) instead of consumption (eating and drinking). Every day as much as 60% of greywater is wasted as a by-product of human consumption. Filtration using local media becomes the treatment option. The size of the greywater particles ranges from 10 μm to 100 μm. The filter media size is made into two levels i.e., 80 mesh (active zeolite and charcoal) and mesh 18 (active sand) to filter particles by ten μm and mesh 14 (zeolite and activated charcoal) and mesh 10 (activated sand) to filter the particle size of 53 μm. The combination of filter media thickness in three experiments took one of the filter media to be used in each experiment. Each experiment will be used one filter media with a thickness of 50 cm and 25 cm each for supporting filter media, with a total media thickness of 100 cm.All of the above become independent variables in research. While the dependent variable is water quality standard in accordance PP. 82 the year 2001 with the main parameters are BOD, COD, TSS, pH, and detergent. The flow rate is set at 24.55 ml / m2 min. Besides the quality standard, the research still refers to cost efficiency and processing time (filtration). All variables consist of 6 filters that give different results; in laboratory test control, only pH fulfills the quality standard of PP. 82 of 2001. This study provides the best combination of filter media in A filter with BOD presentation: 82%, COD: 85%, TSS: 99%, and 98% detergent with the fastest contact time of 2700 seconds. The resulting effluent placed TSS and detergent parameters below the quality standard threshold with TSS values ranging from 15-24 mg / l, while the detergent content was in the range of 14.828 - 42.37 mg / l.

A Study of the Individualism Accounts on American Literature through Reader Response Criticism
Authors: Murwantono Didik
Published: November 2022

This study is by no means a comprehensive account of individualism or more accurately, individualism, in America. It is intended to be more suggestive than comprehensive though it is characterized by more summery than controversy. Many ideas as well as some of the highlights of American manifestations of individualism and modes of individualistic thought and philosophy have been added. What follows, then, is merely a look at some of the high-water marks of literary American individualism and an attempt to offer some cursory explanations for this American phenomenon in theory and practice. This study was under an exploratory qualitative method supported by an interdisciplinary approach of American Studies. Reader-Response criticism is used to make perspective and interpretation without a doubt. The sample was 28 students taking the American Society and literature course at the  Universitas Islam Sultan Agung Semarang. The completion of this research shows the students have creativity and freedom to express their innovation in learning American literature. The cornerstone of individual conscience has to be their credos for changing into a better life through the social, political, economic, and moral autonomy of each individual.

Authors: Dalal Dhaval , Patel Het , Kansara Raj
Published: November 2022

Abstract: High-rise structures are becoming quite common everywhere because of the increasing population and less land area. Generally, High-rise buildings are constructed of RCC, but in RCC buildings due to the bulky size of components of the structure self-weight will be more due to the heavy density of the material. After observing such difficulties, we have come up with the idea of a Steel-Concrete Composite Structure. The composite structure consists of composite columns, beams, and a deck slab which is connected with shear connectors. In this project, the comparative study of f performance of RCC and Composite structure shall be done. The composite structure consists of structural steel and concrete which may provide more ductility and flexibility to the structureand hence it may perform well during an earthquake. The modeling and analysis of the structure shall be done using ETAB software and the parameters like base shear,story drift, displacement, stiffness, strength, period,etc. shall be compared

Published: November 2022

This study aimed to investigate the psychological impacts of the COVID-19 pandemic on parental positive mental health, parenting and child’s behavior. Participants were 150 parents, mostly women (82.0 %), with a mean age of 38 years (SD = 5.4), mothers of children varying between 3 and 11 years of age (M = 6.1; SD = 2.5). Our path analysis model presented a good fit considering the indirect impacts of COVID-19 on parenting and child behaviors through the direct effect on parental mental health. The psychological impacts of the COVID-19 pandemic had a mediated effect through the parents’ mental health on the child’s behavior; however, it had no significant effect on parenting. Our results confirm some expectations reported by Brazilian and international researchers, who predicted impairments in the daily lives of families and the behavior of children during the period of social isolation.

Published: November 2022

Objectives The purpose of this study is to present a teaching plan using a metaverse that allows elementary school learners to immerse themselves in learning with interest and interest as a task-oriented activity that can provide learners with opportunities to directly use English. Accordingly, a plan for elementary English speaking class was presented using Gather.town, one of the metaverse platforms. Methods For this purpose, this study first investigated current task-based instruction models and reformulated a task performance model for elementary English classes. For the task-based class design, the task-based instruction model of Willis (1996) and Skehan (1996) was modified to fit the purpose of this study, and according to the class development, it consisted of the pre-task stage (task introduction), task performance stage (speaking practice), and post-task stage (presentation). As a task-based activity for each stage, a lesson design method using Gather.town was introduced. Results The functions of Gather.town that can be utilized in each stage were introduced, and the class development and activity methods using the functions were presented. The metaverse-using class design model presented in this study can be used in whole or in part as a class operation plan according to the judgment of the teacher, considering elementary school students' cognitive development ability, task performance, proficiency, and English level. Conclusions Through realistic speaking tasks using metaverse, learners' immersion in the task situation can be increased, and it is expected to bring positive effects in terms of learners' interest in class and usefulness in learning to speak. In addition, the educational use of metaverse is expected to provide an opportunity to increase interest in English and improve the listening and speaking skills of English, which is a target language, by practicing English in an elementary English class environment where there are few opportunities to use English directly.

Published: November 2022

Objectives The purpose of this study is to verify the effect of creative problem solving class using e-learning on creative self-efficacy, routine creativity, and problem-solving ability of college students. Methods The class content used in this study was composed based on previously published problem-solving skills textbooks and reference materials. The subjects of this study were 42 students, 22 students who took the e-learning creative problem-solving course opened as a liberal arts course and 20 students who took the general e-learning course at a 4-year university in Busan. As a survey tool, creative self-efficacy, routine creativity, and problem-solving ability scales were used. Results As a result of the study, the creative self-efficacy of college students who participated in the creative problem-solving class using e-learning improved statistically and significantly, but in comparison with the comparison group, there was a statistically significant difference only in creative thinking self-efficacy, which is a sub-factor of creative self-efficacy. In addition, in routine creativity and problem-solving ability, there was no statistically significant difference in comparison with the comparison group. Conclusions These results show that creative problem-solving class using e-learning for university students did not have the same effect as the existing face-to-face teaching methods (discussion-based learning, project(problem) based learning, etc.) However, it confirms the fact that it can be of some help in making college students have the belief that they can be creative or develop alternatives to problem-solving.
The Relationship between the Victimized Experience and the Perpetrating Experience in School Violence among Middle School Students: The Longitudinal Mediation Effect of Perception of School Climate
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Sang-woo , Kim Ji-hyeon
Published: November 2022

Objectives This study selects the school violence victim experience, the perpetrator experience, and the perception of the school climate as major factors, and examines the longitudinal path from the middle school student's school violence victim experience to the perpetrator experience. Most of the studies so far have focused on cross-sectional studies, an aspect of simple change in the relationship between the victim experience and the perpetrator experience and the focus on personal factors. However, not only personal factors but also environmental factors are considered to be important factors in the experience of school violence victimization and the perpetrator experience. Therefore, in this study, the purpose of study was to examine the effect of school factors, in which students spend a relatively large amount of time, on school violence. To this end, we intend to verify the mediating effect of the school violence victimization experience leading to the school violence perpetrator experience through the perception of school climate through longitudinal study data. Methods For this purpose, data from 2013(middle school 1) to 2015(middle school 3) among panel 1 data of the Seoul Education Longitudinal Study 2010 were used. The total number of subjects was 2,411, and the data were analyzed using the autoregressive cross-delay model. Results The victimization experiences and perpetrating experiences of school violence at the previous point affects the victimization experiences and perpetrating experiences of school violence at the next point in time, respectively, and that the previous perception of school climate also affects the perception of next time. In addition, the victimization experience of school violence at the previous point (middle 1) affects the perception of the school climate at the next point (middle 2), and the perception of the school climate at the previous point (middle 2) affects the perpetrating experience of school violence at the next point (middle 3). In other words, the study confirmed that the perception of the school climate had a longitudinal mediating effect in the relationship between the victimization experience and the perpetrating experience. Conclusions These imply that the victimization experience of school violence at the previous point can lead to the perpetrating experience of school violence next time. Also, if a student perceives the school climate negatively in this path, the perpetrating experience of school violence in the future may increase.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Jo Hyeyoung
Published: November 2022

Objectives The purpose of this study is to find out the effectiveness of Nano-LAB subjects using flipped learning for teacher efficacy, meta-cognition, and intrapersonal intelligence of early childhood teachers. Methods Seven students who took the Nano-LAB class among the Department of Early Childhood Education at A University in Chungcheong-do were the subjects of this study. Pre-tests and follow-up tests were conducted to measure the variable of teacher efficacy, meta-cognition, and intrapersonal intelligence. We tested the normality with Kolmogorov-Smirnova test (K-S) and Shapiro-Wilk test (S-W) using SPSS 23.0, and analyzed the difference between the pre-average score and post-average score with Wilcoxon as statistical significance. Results The main results are as follows. First, although most of the research variables satisfied the normality, there was a statistically significant difference between the sub-variable of teacher efficacy, personal teacher efficacy K-S post-score and meta-cognition K-S pre-score and the sub-variable, planning S-W post-score. Second, for the difference between the pre-average score and the post-average score in the view of the statistical significance, there was a statistically significant difference between teacher efficacy and the sub-variable, personal teacher efficacy, while there was no difference in general teacher efficacy. While statistically significant differences were found in meta-cognition and the sub-variables such as planning and inspection, no differences were found in regulation. There were statistically significant differences in intrapersonal intelligence and the sub-variables such as self-understanding, self-design, self-regulation, and emotional utilization, but there was no difference in self-reflection. Conclusions The results of this study can be uses as basic data to provide directions to conduct flipped learning more effectively when operating subjects other than regular curriculum. In addition, we discussed the ways to lead competency-oriented education.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Park Kyoungjin , Lee Somi
Published: November 2022

Objectives In this study, the purpose of this study is to examine whether the Dunning-Kruger effect, which is a biased confidence in one's ability according to the type of question in the science subject, appears in middle school students, suggesting a learning method, and removing the negative factors of learning. The purpose of this study is to respond to the demands of the school to present a learning strategy that minimizes the discrepancy between academic expectations and academic achievement, and to prepare a basis for implementing it. Methods For 215 second-year coeducational middle school students located in Gyeongsangbuk-do, we had them predict the expected scores for each of the multiple-choice and short-answer types of test questions before the first science test in the second semester of 2021. A significant relationship was verified by analyzing the relationship between quartiles based on actual grades and expected grades, and t-testing. Results A significant negative correlation was confirmed between the expected score and the difference score (the gap between the expected score and the actual score), and it was also confirmed that the overestimation of the short-answer type was larger than that of the multiple-choice type question. By confirming the two-way phenomenon of overestimation of students with low academic achievement and underestimation of students with good grades, the Dunning-Kruger effect, a previous study, was also found in Korean middle school students. Conclusions The correlation between the student's actual achievement score and the difference score was negative (-) in both multiple-choice and short-answer types for each test item type. There is a significant difference between the actual grades and quartiles in estimating the expected scores for multiple-choice and short-answer types. We present a learning strategy to provide opportunities for self-directed learning that accurately judges one's own abilities, expand the question-and-answer-type question type method in the school field, and check whether there are factors that affect cognitive bias in addition to the question type.
Usage of Comparison/Contrast Pattern in Undergraduate Academic Essays
Authors: Farneste Monta
Published: November 2022

The present paper discusses undergraduate essay writing in English as a Foreign Language (EFL) in Latvia. The goal of the paper is to examine the basic problems in student comparison/contrast essays. The analysis of 23 essays revealed that some students had problems with determining the purpose of communication and selecting an appropriate thesis statement to fulfil the task. Moreover, another problem was linked with the choice of the topic sentences and their supports which develop the controlling idea of the thesis statement, as well as the choice of information for the concluding paragraph. The analysis of the rhetorical patterns and linguistic signals revealed that one essay might display features of several patterns: comparison/contrast, description, problem- solution, cause-effect, illustration. Thus, the research showed that structuring of the comparison/ contrast essay in the target language is one of the problematic aspects in EFL undergraduate writing in Latvia.

Published: November 2022

The aim of the study is to examine the syntactic pattern of the frequency of use of simple, complex and compound sentences focusing on different subordinate clauses as critical features in the written learner text corpora at different English and French language acquisition levels in the texts produced by secondary school test-takers in Latvia. The theoretical basis of the research is Pienemann’s Processability theory. For the purpose of quantitative and contrastive analysis of syntactic structures written learner text corpora in English and French have been compiled, in which different clauses have been marked by manual annotation and afterwards classified according to different syntactic patterns. Subordinate clauses have been grouped applying Dik’s taxonomy of embedded constructions. The preliminary research has discovered some similarities and differences between the syntactic pattern usage at the same language acquisition levels.
Politeness Strategies in Electronic Communication: The Speech Act of Request
Authors: Karapetjana Indra , Roziņa Gunta
Published: November 2022

Linguistic politeness plays an important role when establishing respectful interpersonal relationships in any communicative situation, the academic context including. The speech act of request can become a face- threatening act if language users are unable to adapt their language use to the social variables determined by the context of use. The present study aimed at establishing an understanding of the negative politeness strategies and request strategies used by tertiary level students in electronic communication in English. Schauer’s (2009) request strategies and Levinson’s (1987) seminal work on politeness strategies laid the foundations for the present paper. The framework by Biber and Conrad (2009) for analysing situational characteristics proved a valuable resource for the case study, which drew its data from a corpus of email messages written in the time period from August 9, 2010 to June 25, 2011. The obtained data demonstrated that the Latvian students tended to use direct and conventionally indirect request strategies at the same time employing such negative politeness strategies as being conventionally indirect, hedging, minimizing the imposition, and apologizing. The hedged performatives used in the direct requests mitigated the illocutionary force of the utterance. However, the impositive face-threatening nature of the speech act of requesting determines the necessity of raising English as a foreign language students’ awareness of conventionally indirect request strategies and mitigating devices in a variety of contextual situations in order to guarantee the need of individuals to be respected and appropriately understood.

Aim: The present investigation was designed to study the impact of artificial light at night on the phenological phases and yield contributing traits of fodder oat variety Kent for holistic breeding along the roadsides or highways. Methodology: The experiment was conducted at Central Research Farm of ICAR-IGFRI, Jhansi, India, in a plot under natural conditions. The treatment Lc (controlled) was under natural conditions receiving normal daylight and dark periods. However, treatment L1 (300-350 lux), L2 (200-300 lux), L3 (100-200 lux), and L4 (10-50 lux) were different light affected areas having distances 0, 5, 10, and 15 m from the light source. Duncan's test, OPSTAT, and SPSS version 16.0 software were used for statistical analysis. Results: The vegetative growth parameters such as plant height, total leaf area, flag leaf area, days to 50% flowering, panicle length, total dry biomass, and test weight were increased linearly as the distance increased from the artificial light source (minimum value for L1 treatment and maximum for Lc). However, plant population per meter square was maximum for L1 treatment and minimum for local control (Lc; no night light effect). Moreover, it is the first report of artificial light at night on the fodder oat from India and concluded that night light significantly affects the plant phenology and yield potential, and opens a new research paradigm on plant-artificial light at night interactions. Interpretation: Plants close to the light source received maximum intensity of night light (L1) than distantly located treatments (L2, L3, and L4). Artificial light at night-time had adverse effects on the yield-contributing traits and showed a significant negative relationship.

Aim: In-vitro characterisation of biofilm produced by Mycobacterium smegmatis (M. smegmatis), a surrogate model for biofilm production by Mycobacteria, and to evaluate the impact of different environmental stress on mycobacterial growth and biofilm formation. Methodology: M. smegmatis biofilms were studied using tissue culture plate and tube adherence methods. Confocal Laser scanning microscopy (CLSM) and scanning electron microscopy (SEM) were used to study the 3D structure and surface morphology, respectively. Additionally, the effect of different environmental stress, such as the absence of essential ions, exposure to harsh environmental conditions, such as acidic environment or oxidative stress, on mycobacterial biofilm formation and mycobacterial growth was assessed. Results: All the exposures, except for carbon supplemented media had a detrimental effect on the number of viable counts and on biofilm formation by mycobacteria (p<0.001). Growth in low pH and oxidative stress was found to be maximum showing reduction by 98% when compared with control. Interpretation: Our findings present various environmental conditions that profoundly affect biofilm formation and thus, may find practical implications in future as effective mycobacterial control strategies having attributes of mycobacterial growth as well as biofilm inhibition.

Aim: Analysis of chemical composition and assessment of biological potential of tasar exuviae extracts. Methodology: The biochemical components such as proteins, chitin, ash, fat, moisture, minerals and carbohydrate were estimated in the exuviae. After extraction, glowing pigments were characterized by UV-Vis and fluorescent spectra, and profiling of polyphenolic and flavonoids, free radical scavenging assay, antibacterial and anticancer potential were evaluated. Results: The proximate components such as proteins, chitin, ash, fat, moisture, and carbohydrate contents were 62, 11.52, 10.57, 3.9, 3.1 and 0.9%, respectively. Further, among different elements, calcium level was higher than other elements such as magnesium, manganese, copper, zinc and sodium. The methanolic extract exhibited free radical scavenging and anti microbial potential in concentration dependent manner. In addition to these, glowing compounds prominent cytotoxic effect against breast cancer cell lines viz. MCF7, BT474 and SKBR3. Interpretation: The action mechanism of extract could be probably due to the presence of yellow flavonoids (luteolin, catechin, epicatechin and quercetin) and phenolic acids (p-coumaric acid, gentisic acid and gallic acid), which glows during exposure of UV light and having biological potentials.

Aims: To describe the medication changes implemented during
physician-led medication reviews that resulted in improved
health-related quality of life; and to explore factors that could
identify patients with overprescription. Methods: Post-hoc
analyses of data from a pragmatic, non-blinded, randomized clinical
trial investigating a medication review intervention (NCT03911934) in
408 geriatric outpatients taking ≥9 medicines. Results: The
most frequent medicine change in the medication review group (n=196) was
discontinuation (26% of the medicines) due to lack of indication (72%
of the discontinuations). After 13 months, 82% of the discontinued
medicines were persistently discontinued. The medicines most often
discontinued in the medication review group compared with usual care
included: metoclopramide (11/5=73% discontinued vs 1/12=8% in usual
care), acetylsalicylic acid (20/48=42% vs 2/47=4%), simvastatin
(18/48=38% vs 2/58=3%), zopiclone (23/59=39% vs 4/54=7%), quinine
(9/14=64% vs 6/16=38%), citalopram (4/18=22% vs 0/20=0%), and
tramadol (18/37=49% vs 8/30=27%). Factors associated with the number
of overprescribed medicines included: number of prescribed medicines
(8% increase per medicine), Drug Burden Index (15% increase per 1
increase), and patient motivation for medicine changes (26% less if not
motivated). Prescriptions of metoclopramide, iron preparations,
antidepressants other than SSRIs, NSAIDs, or drugs for urinary
incontinence were associated with a higher number of overprescribed
medicines. Conclusion: Medication reviews can be used to
persistently discontinue overprescribed medicines in older polypharmacy
patients. Motivation for having their medicine changed, treatment with a
higher number of medicines, and a higher burden of sedative and
anticholinergic drugs characterized patients most likely to benefit from
physician-led medication reviews.
