Published: May 2023

Dam decommissioning (DD) is used to solve economic and social problems posed by old dams. However, we ignore the effect of DD on the content and reactivity of large stocks of organic matter (OM) buried in reservoir sediments. We explored temporal changes in the content and reactivity of sediment OM during the first 580 days after the drawdown phase of DD of a large reservoir in the N Iberian Peninsula. We determined the content of sediment OM as organic carbon (OC) in bulk sediment OM and water-extractable OM (WEOM). We estimated the reactivity of bulk sediment OM as its respiration rate and carbon-to-nitrogen ratio, and that of sediment WEOM as its respiration rate, percent biodegradable dissolved OC (%BDOC), and SUVA254. The content of bulk sediment OM was 84 ± 5.1 (mean ± SE) mg OC/ g dry sediment, comparable to the values in the literature on sediment OM in dry sediments from lentic, but higher than in lotic ecosystems. The content of sediment WEOM was 0.81 ± 0.05 mg DOC/g dry sediment, higher than the values in the literature on sediment WEOM from lakes, soils, and rivers. On average, 41 % of WEOM was consumed by microorganisms in two days of incubation, showing the great reactivity of this OM fraction. The content of bulk sediment OM and the respiration rate of WEOM showed a nonlinear temporal trend, while %BDOC increased linearly with sediment exposure time. The labile OM produced by the vegetation that rapidly recolonized the reservoir and photoreactions may explain the temporal increase in %BDOC. Our results suggest that exposed sediments can be a source of labile OM and high C emissions in the river reach downstream of the reservoir after DD.

Democracy In Türkiye and Indonesia
Authors: Soydan Mustafa Zafer , Setiawan Refly
Published: May 2023

Currently, democracy has given its place to people all over the world, both in Türkiye and Indonesia. In various countries, especially in Türkiye and Indonesia, the government is always faced with various problems, especially related to democracy. One of the problems of democracy in Türkiye is related to the social structure. In Turkish society, where traditional social characteristics are dominant, individual life is not a pleasant lifestyle and social characteristics do not allow it. Although the ongoing modernization efforts throughout the history of the Republic of Türkiye have united the society with modern life to some extent, when viewed as a whole, it is seen that the society still develops attitudes and behaviors suitable for the characteristics of Turkish culture. In addition, Indonesian society also has its own characteristics, and the way in which Indonesia implements democracy also refers to the situation of a multi-ethnic country, so every policy made by the government takes great care not to cause political turmoil in the society. In this study, the researcher places more emphasis on the theories and concepts of democracy related to Türkiye and Indonesia. Several theories related to democracy are used to support this research in order to provide a clear picture of democracy in Türkiye and Indonesia.

Shortened first regrowth interval of grass silage as a harvesting strategy to improve nutrient supply for dairy cows: a case study
Authors: Sairanen Auvo , Kajava Sari , Palmio Annu , Rinne Marketta
Published: May 2023

Dairy cows have a highly valuable ability to convert grass into milk. A modification of the normal three-cut harvesting strategy was evaluated consisting of shortened first grass regrowth period to increase the energy value of the silage crop over the whole growing season under Boreal conditions. Grass was ensiled from timothy-meadow fescue-red clover swards over two years at three consecutive harvests within the growing season. Diets based on the silages (D1, 1st cut; D2, 2nd cut and D3, 3rd cut) were fed to dairy cows in two milk production experiments using change-over designs and an average concentrate proportion of 0.41 on dry matter basis. Consistently high energy value in silages was achieved and despite minor differences in silage D-values, feed intake was highest for D1. The differences in energy-corrected milk yield between treatments were limited to an increase for D2 in Exp 2 so that feed energy conversion into milk was decreased with D1. A shortened first regrowth interval for grass silage harvest was a viable option, but forage area per animal and other farm specific factors should be considered when choosing the silage harvesting strategy.

Published: May 2023

The diabetic wounds are one of the global burden diseases. In our previous study, Ageratum conyzoides L. leaf ethanolic extract (purple flower type) 10%, Centella asiatica (L.) Urban leaf ethanolic extract 5%, and astaxanthin 0.1% combination gel preparation showed remarkable wound healing effectivity. However, this wound healing effectivity in the diabetic condition is still unknown. There were three groups used, namely negative group (placebo/gel base), positive group (oxoferin/tetrachlorodecaoxide), and test group (Ageratum conyzoides L. leaf ethanolic extract (purple flower type) 10%, Centella asiatica (L.) Urban leaf ethanolic extract 5%, and astaxanthin 0.1%). Each group consisted of three male Wistar rats. We conducted diabetes induction with alloxan (175 mg/Kg BW i.p) and followed by an incision 1.5 cm on the back. All of these groups were given treatment once daily and monitored for 14 days. The results of the study showed the test group indicated significantly better effectivity than positive and negative groups (p<0.05). The percentages of the wound healing effectivity of the test, positive and negative groups were 62.74%, 51.77%, and 41.65%, respectively. Ageratum conyzoides L. leaf ethanolic extract (purple flower type) 10%, Centella asiatica (L.) Urban leaf ethanolic extract 5%, and astaxanthin 0.1% combination gel preparation has excellent potential to be developed as a commercial product to treat diabetic wound conditions.

Published: May 2023

The aim of this investigation was to assess the clinical use of alfaxalone as a short-acting anaesthetic agent for induction to inhalation anaesthesia in jungle carpet pythons (Morelia spilota cheynei). Ten healthy, captive, sub-adult jungle carpet pythons (1.1±0.32 kg bw) were anaesthetised using a dose of 10mg/kg of alfaxalone, administered intravenously to the ventral tail vein. Heart rate (HR) and respiratory rate (RR) were recorded before administration (T0), and every 5 minutes until the snakes fully recovered from the anaesthesia. The induction time, time of tail-pinch reflex loss, tracheal tube insertion time, interval of deep anaesthesia, and the time of full recovery were recorded. The induction time occurred within 3.1±0.8 minutes. The tail-pinch reflex loss was lost within 5.6±0.7 minutes. The mean tracheal tube insertion time, the interval of deep anaesthesia, and the time of full recovery were 6.9±0.9 minutes, 18.8±4.7 minutes, and 36.7±11.4 minutes, respectively. A prolonged time of full recovery was recorded in two snakes (61.3 and 62.6 minutes, respectively). Their mean heart rate was statistically higher (P<0.05) at T5, T15 and T20 when compared with the basal HR at T0. The respiratory rate of the snakes dropped at T5 and was statistically lower (P<0.05) from T5 until T20 when compared with RR at all other time points. In two snakes apnoea was recorded at T5. Intravenous administration of alfaxalone proved to be a valuable method of induction, suitable for a subsequent inhalation anaesthesia in jungle carpet pythons.

The objective of the present study was to determine the effect of oral supplementation of dairy cows with a combination of fish oil and vitamin E (Vit E) from approximately 7 days (d) before the expected calving date up to 21 days postpartum, on their reproductive performance and metabolic profile. Eighty Holstein multiparous cows were randomly assigned into one of two ration groups during the transitional period. The treatment group cows (n=40) received a transitional diet (pre-and post-partum based on the NRC 2001) supplemented with fish oil (FO, 100 g/ once per day +Vit E (8000IU/kg/d); and the control cows (n=40) received the same concentrate without FO. Blood samples were collected at 1 week before the expected calving date, and 1, 2 and 3 weeks postpartum. After a voluntary waiting period, all cows received timed artificial insemination (TAI) at 76-81 days in milk (DIM) following the PresynchOvSynch protocol. Pregnancy diagnosis was performed 30-40 days after TAI using a transrectal ultrasonography. Our results showed that the cows fed the FO+Vit E diet had a statistically higher first service pregnancy rate (46.3 % vs. 39.6%, P<0.001) at 30-40 days after TAI than those fed the control diet. Also, cows that consumed the FO+Vit E treatment diet had lower late embryo loss at 40-70 days post insemination than the control. Plasma concentrations of triglycerides (d7, 14, and 21), cholesterol (d7 and 14), glucose (d14), insulin (d-7) progesterone (d14 and 21) in the treatment group were higher (P<0.05) compared to the cows fed control diets. Non-esterified fatty acid (NEFA) levels were not significantly affected by the dietary treatments pre-partum, while β –hydroxybutirate acids (BHBA) levels on day 21 (P<0.05) were higher in the control group. The results indicated that supplementation of the diet with fatty acid and high doses of vitamin E could improve reproductive performance in dairy cattle.

Mycoplasma synoviae (MS), despite its lower pathogenicity, has the ability to cause significant losses in poultry production but is usually underdiagnosed. In egg layer production, losses could be significant because of the drop in egg production and poor eggshell quality. Problems with colibacillosis and other infections secondary to MS have been continuously reported on Croatian egg layer farms. As a result, regular monitoring of flocks also included screening of the seroprevalence and molecular detection of MS using ELISA and qPCR tests, respectively. During monitoring, altogether 1135 samples were tested, including 1067 serum samples and 68 tracheal swabs, in a total of 126 flocks and 83 longitudinally merged flocks on 15 farms during the period from 2017 to 2021. The results showed a high general prevalence of MS with 86.6 % positive layer farms, while grouped flock seroprevalence and prevalence were 98.6% and 85.7%, respectively. With age, seroprevalence and ELISA titers rise significantly compared to the rearing period, with a significant mutual correlation over the entire production period. Additionally, there is a significant correlation between ELISA titers and age in weeks. Several flocks covered longitudinally from the first week of age, over the rearing period to the end of production, showed low prevalence during the rearing period, with a later significant rise in titer and prevalence, which indicates the dominance of horizontal transmission during production. Overall results indicate the need for a prompt reaction regarding preventive measures, such as better flock management, biosecurity and vaccination, which would reduce the losses and improve production.

The purpose of this study was to investigate the effect of high-intensity interval, aerobic, and resistance training, and spirulina supplement consumption on the levels of Uncoupling Protein-1 (UCP1), Transient Receptor Potential Vanilloid (TRPV1) and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) in the white adipose tissue of diabetic rats. A total of 42 male rats with diabetes type II were randomly assigned into seven groups as follows: aerobic training (n=6), resistance training (n=6), interval training (n=6), aerobic training combined with supplementation (n=6), resistance training combined with supplementation (n=6), interval training combined with supplementation (n=6) and control (n=6) groups. The training groups carried out the training (8 weeks/5 days) on a rodent treadmill and ladder. The paired sample t-test and one-way ANOVA were employed for data analysis. The three kinds of training, with and without supplementation, significantly reduced mass, glucose, insulin, and insulin resistance. In the three supplementation-combined training groups the difference on the HOMA-IR index was significant; however, the decline was larger in the resistance training with supplementation group. The concentration of UCP-1 and TRPV1 proteins significantly increased in all training groups, with and without supplementation. Nonetheless, the significant increase in the UCP-1 levels in the interval training with supplementation group was more than in the other groups. Furthermore, the TRPV1 protein levels were higher in the resistance training with supplementation group. Eight weeks of training, with and without Spirulina supplementation, reduced insulin resistance and gave rise to significant changes in UCP-1 and TPRV1 concentrations.

Many of the challenges in the estimation of dynamic heterogeneous treatment effects can be resolved with local projection (LP) estimators of the sort used in applied macroeconometrics. This approach provides a convenient alternative to the more complicated solutions proposed in the recent literature on Difference in-Differences (DiD). The key is to combine LPs with a flexible ‘clean control’ condition to define appropriate sets of treated and control units. Our proposed LP-DiD estimator is clear, simple, easy and fast to compute, and it is transparent and flexible in its handling of treated and control units. Moreover, it is quite general, including in its ability to control for pre-treatment values of the outcome and of other time-varying covariates. The LP-DiD estimator does not suffer from the negative weighting problem, and indeed can be implemented with any weighting scheme the investigator desires. Simulations demonstrate the good performance of the LP-DiD estimator in common settings. Two recent empirical applications illustrate how LP-DiD addresses the bias of conventional fixed effects estimators, leading to potentially different results.

Authors:   Korea Univ. Institute of Educational Research, CHOI JUNG HEE
Published: May 2023

The purpose of this study is to examine the meaning of home education as perceived by Intellectuals during the Patriotic Enlightenment Period (1905-1910). The term ‘Home education’ first appeared around the early 20th century and is a modern term that began to be used in earnest after the Patriotic Enlightenment Period. The meaning of ‘Home education’ can be summarized as follows: First, Home education had the meaning of a field of modern education. ‘Home education’ was new knowledge learned intentionally and professionally through public discussion. Additionally, it was considered intentional and professional education for the holistic development of children, serving as the foundation for all education.
Second, Home education meant parents educating their children as ‘educators’. ‘Home education’ meant parents with modern knowledge educating their own children. Parents had to possess specialized knowledge about child education for their children's happiness and ultimately for the independence and prosperity of their country.
Home Education during the Patriotic Enlightenment Period has value in that it began as education that everyone, regardless of status and gender, should learn as a field of modern regular education, and it provides insights into the ‘educational role of parents’ today.
Review of the Conflicting Interpretations of Zhuxi’s Theory of Knowledge and Practice by Modern Chinese Confucianism Scholars: Focusing on Kwong-loi Shun’s Acceptance and Chen Lai’s Criticism
Authors:   Korea Univ. Institute of Educational Research, Han jiyoon
Published: May 2023

The purpose of this study is to clarify Zhuxi’s theory of knowledge and practice by reviewing the conflicting interpretations of modern chinese confucianism scholars. Kwong-loi Shun, who accepts Zhuxi, argues that Zhuxi’s knowledge means moral knowledge rather than empirical knowledge and that knowledge is revealed through action. In contrast, Chen Lai, who criticizes Zhuxi, argues that Zhuxi does not discuss how knowledge is achieved or how it is revealed through action. As a result of critically examining all conflicting views, unlike Kwong-loi Shun, Zhuxi sees both empirical knowledge and moral knowledge as one principle. And contrary to Chen Lai’s criticism, Zhuxi discusses how knowledge is achieved by practicing after knowing true it. This is seen as a way to achieve knowledge by forming beliefs according to true knowledge by seeing and hearing everything in an always awake state. This research has educational implications in that it can reveal the original meaning of Zhuxi’s theory of knowledge and practice when critically reviewing the interpretations of Kwong-loi Shun and Chen Lai.

Published: May 2023

Differentiated instruction is a form of teaching. The content, processes, products, or learning environment can be differentiated with respect to students' readiness to learn, interests, and learner profiles. Enrichment, one of the differentiation strategies, can be described as the student’s intensive work on any subject or area. Using game elements can also impact students' achievement, mathematics attitude, and motivation. The aim of this study was to investigate the influence of activities enriched with game elements on students’ learner profiles in mathematics lessons and their achievement, motivation, and attitudes. This current study used the quantitative quasi-experimental approach with 24 6th-grade students during two weeks. The Learner Profile Scale was used on the students and then mathematics activities with game elements were prepared for experimental group. An Academic Achievement Test and Attitude and Motivation Towards Mathematics Scales were used as data collection tools before and after the implementation of activities enriched with game elements. Mann Whitney U Test is used to analyse the differences between experimental and control group. Wilcoxon Signed Rank Test is used to analysed the difference pre- and post-test both experimental and control group. According the result significant point for students’ academic achievement, motivation and attitude is found as .229, .002 and .043 respectively. Effect size is calculated for students’ academic achievement, attitudes and motivation as .34, .58 and .58 respectively. As a result of this study, the use of enriching game elements had positive and larger effect on students’ motivation, and attitude in mathematics lessons. Although the differences between experimental and control group is not found significantly for the student's achievement, there is a difference between pre- and post-test and the size of effects is calculated as medium. Hence, the educational gamify activities should be design by considering the students’ types.

This study determined the associations between Zoom fatigue and satisfaction with online learning among nursing students in a higher institution of learning in the Philippines. A cross-sectional research design was employed and a web-based survey using two self-report measures was conducted in 2021. Descriptive statistics, Pearson's correlation, and linear regression were used to analyze the responses of 408 student respondents. The sample demonstrated high levels of Zoom fatigue and low to average online learning satisfaction. There was a significant difference in the Zoom fatigue levels between male and female students. Higher Zoom fatigue levels predicted reduced online learning satisfaction. This study underscores that online learning and virtual meetings have a likely negative impact on students' online learning experiences. Nursing schools may need to reconsider the existing learning and teaching strategies and start measures that will foster more meaningful and positive experiences in the virtual learning environment.

Authors: Eseadi Chiedu
Published: May 2023

The occurrence of corona virus disease in 2019 (Covid-19) pandemic with its negative consequences on various sectors including education up till now has led to the increase in the necessity to use online learning resources and platforms for teaching and learning especially in higher education institutions (HEIs) in various countries. This research paper's major goal was to investigate the online learning attitude and online learning readiness of undergraduate accounting students in Nigerian public HEIs during the Covid-19 pandemic. The research participants consisted of 845 male and female undergraduate accounting students purposively selected from six HEIs. Study data was collected quantitatively with two online learning scales addressing students' online learning attitude and online learning readiness respectively. The study data were analysed with relevant statistical tests in the Statistical Package for the Social Sciences (SPSS, version 22) based on .05 level of significance criteria. The finding demonstrates significantly positive online learning attitude among the undergraduate accounting students from the studied HEIs during the Covid-19 pandemic. Finding also showed that the undergraduate accounting students' online learning attitude significantly related to their online learning readiness during the Covid-19 pandemic. The male and female undergraduate accounting students did not differ in their online learning attitude and online learning readiness. There were no significant differences in online learning attitude and online learning readiness among the undergraduate accounting students from the studied HEIs based on institution type (university, polytechnic and college of education). Nigerian HEIs and accounting departments should provide efficient online learning access and resources to these students and work towards bridging any existing institutional disparities in the availability and use of online learning facilities and resources.
Product Recommendation System Based on Deep Learning
Authors: Lu Ping , Liu Pingping
Published: May 2023

With the development of Internet big data and e-commerce, the widespread popularity of information, information acquisition and personalized recommendation technologies have attracted extensive attention. The core value of personalized recommendation is to provide more accurate content and services around users. The recommended scenarios are not uniform, and different dimensions need to be considered. For example, we are facing enterprises or individuals, different age groups, different levels of education, social life and other aspects. In this paper, the classic DNN (Deep Neural Networks) double tower recommendation algorithm in the recommendation algorithm is used as the ranking algorithm of the recommendation system. It is divided into user and item for embedding respectively. The network model is built using tensorflow. The data processed by the initial data through feature engineering is sent into the model for training, and the trained DNN double tower model is obtained. Recall adopts collaborative filtering algorithm, and applies tfidf, w2v, etc. to process feature engineering, so as to better improve the accuracy of the system and balance the EE problem of the recommendation system. The recommendation module of this system is divided into data cleaning as a whole. Feature engineering includes the establishment of user portraits, the analysis of multiple recall and sorting algorithms, the adoption of multiple recall mode, and the implementation of a classic recommendation system with in-depth learning. This makes the recommendation system better balance the interests of both the platform and users, and achieve a win-win situation.
