Behavior-Aware English Reading Article Recommendation System Using Online Distilled Deep Q-Learning
Authors: Zheng Ting , Ding Min
Published: June 2023

Due to the differences of students' English proficiency and the rapid changes in reading interests, online personalized English reading recommendation is a highly challenging problem. Although some works have been proposed to address the dynamic change of recommendation, there are two issues with these methods. First, it only considers whether students have read the recommended articles. Second, these methods often fail to capture the real-time changing interests of users. To address the above challenges, a deep Q-network based recommendation framework was proposed. The authors further use the user's behavior and scores as reward information to get more user's feedback. In addition, a personalized adaptive module was introduced to capture the short-term interests on the fly and utilized the consistent loss of KL divergence to distill the knowledge from the online model. Extensive experiments on the offline and online dataset in the IWiLL website demonstrate the superior performance of the method.

Online reviews have a continuing impact across all industries. Even industries with highly skilled workers are affected by online reviews, despite large gaps in experience and skill between reviewers and reviewees. The authors conducted a study amongst physicians in Nevada and China to measure the perception of online patient reviews from the perspective of healthcare providers to explore whether this skill gap affected the perception of online reviews. The authors distributed and collected survey responses from over 200 physicians and used structural equation modeling techniques to evaluate the relationships. These findings show that physician perception of online patient reviews is partially mediated by power distance, direct effects exist between the relationships identified in our model, and that cross-cultural effects are present between physician responses across Nevada and China. This study expands the existing work in the field of review evaluations by operationalizing social-psychological distance into the construct of power distance within the context of healthcare.

Poultry selling is beyond the ambit of industrial processing and marketing trade at Live Bird Market (LBM) operations. Contaminated meat from such LBM is being increasingly recognized as a potential source of food borne disease including salmonellosis. At present, limited information is available on processing and marketing of live birds in informal LBM operations of Sri Lanka. This cross-sectional study was carried out to describe the characteristics of LBM and to determine Salmonella prevalence with special emphasis on the risk practices that could lead to cross contamination. We analysed 123 LBM operations in Sri Lanka using a pretested and structured questionnaire, visual observations by trained enumerators, and culture and isolation of Salmonella to achieve above objectives. The observed characteristics of the LBM in Sri Lanka were generally similar to those operated in other Asian countries even though there were minor variations. Overcrowding of live birds, keeping meat at ambient temperatures and improper evisceration practices leading to cross contamination were some of common characteristics seen in majority of the LBM operations. Regarding Salmonella prevalence, it was moderate in LBM of Sri Lanka (47.97 %) while low prevalence was observed in both poultry meat sold at LBM (30.89%) and meat contact surfaces (

Published: June 2023

Vaccination of dogs against canine distemper virus (CDV) and canine adenovirus (CAV), are recommended to prevent severe disease outbreaks caused by those viruses. Antibody (Ab) titre testing has proven to be an effective method of monitoring immunity and determining whether re-vaccination is necessary. Postvaccinal immunoglobulin (IgG) titres specific for CDV and CAV with three selected commercial multivalent vaccines (A, B, and C) were evaluated in this study. When antibody titres of a total of 40 client-owned dogs (16 vaccinated with vaccine A, and 12 each with vaccine B and C) were tested three weeks after the primary vaccination using VacciCheck in-clinic test kit, only 33 yielded valid responses. Pair-wise comparison using the Kruskal-Walli’s test showed that vaccine C induced a significantly higher CDV-specific Ab titres (p = 0.001) than vaccine A or B. Both vaccines A and C induced significantly high levels of CAV-specific Ab titres (p =0.001) when compared to vaccine B. Vaccine B containing the Rockborn strain of CDV and Manhattan strain of CAV induced a very poor immune response against both viruses. Since many factors can affect the immune response elicited by a vaccine, selecting a reliable vaccine product is important to ensure a good immune response. The vaccine C produced by a leading manufacturer containing the viral titres of 1x104 TCID50 and 1x106 TCID50 or CDV and CAV, respectively was effective in inducing a protective humoral immune response in all dogs tested in this study.

Published: June 2023

Recipient T cells can aggravate or regulate lethal and devastating graft-versus-host disease (GVHD) after bone marrow transplantation (BMT). In this context, we have shown before that intestinal immune conditioning with helminths is associated with survival of recipient T cells and Th2 pathway–dependent regulation of GVHD. We investigated the mechanism of survival of recipient T cells and their contribution to GVHD pathogenesis in this helminth infection and BMT model after myeloablative preparation with total body irradiation in mice. Our results indicate that the helminth-induced Th2 pathway directly promotes the survival of recipient T cells after total body irradiation. Th2 cells also directly stimulate recipient T cells to produce TGF-β, which is required to regulate donor T cell–mediated immune attack of GVHD and can thereby contribute to recipient T cell survival after BMT. Moreover, we show that recipient T cells, conditioned to produce Th2 cytokines and TGF-β after helminth infection, are fundamentally necessary for GVHD regulation. Taken together, reprogrammed or immune-conditioned recipient T cells after helminth infection are crucial elements of Th2- and TGF-β–dependent regulation of GVHD after BMT, and their survival is dependent on cell-intrinsic Th2 signaling.

Cachexia is a major cause of death in cancer and leads to wasting of cardiac and skeletal muscle, as well as adipose tissue. Various cellular and soluble mediators have been postulated in driving cachexia; however, the specific mechanisms behind this muscle wasting remain poorly understood. In this study, we found polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) to be critical for the development of cancer-associated cachexia. Significant expansion of PMN-MDSCs was observed in the cardiac and skeletal muscles of cachectic murine models. Importantly, the depletion of this cell subset, using depleting anti-Ly6G Abs, attenuated this cachectic phenotype. To elucidate the mechanistic involvement of PMN-MDSCs in cachexia, we examined major mediators, that is, IL-6, TNF-α, and arginase 1. By employing a PMN-MDSC–specific Cre-recombinase mouse model, we showed that PMN-MDSCs were not maintained by IL-6 signaling. In addition, PMN-MDSC–mediated cardiac and skeletal muscle loss was not abrogated by deficiency in TNF-α or arginase 1. Alternatively, we found PMN-MDSCs to be critical producers of activin A in cachexia, which was noticeably elevated in cachectic murine serum. Moreover, inhibition of the activin A signaling pathway completely protected against cardiac and skeletal muscle loss. Collectively, we demonstrate that PMN-MDSCs are active producers of activin A, which in turn induces cachectic muscle loss. Targeting this immune/hormonal axis will allow the development of novel therapeutic interventions for patients afflicted with this debilitating syndrome.
Three-Dimensional Modeling of Solid Tumors and Their Microenvironment to Evaluate T Cell Therapy Efficacy In Vitro

Published: June 2023

Immunotherapy development for solid tumors remains challenging, partially due to a lack of reproducible, cost-effective in vitro three-dimensional (3D) models to mimic the heterogeneous and complex tumor microenvironment. Here, we investigate the cellular anti-tumor reactivity of αβ T cells engineered to express a defined γδ TCR (TEG A3). For that purpose, we developed a 3D cytotoxicity assay targeting cell line–derived spheroids or patient-derived tumor organoids formed in serum-free media. Tumor cell lysis by TEG A3 was monitored using the Incucyte S3 live-cell imaging system with the apoptosis marker caspase 3/7 green and endpoint readouts of IFN-γ secretion in the supernatant. The 3D cytotoxicity assay model system was able to adequately demonstrate TEG A3 reactivity toward targets expressing an isoform of CD277 (CD277J). To obtain a more complex heterogeneous tumor microenvironment, patient-derived organoids were mixed with unmatched patient-derived fibroblasts or matched cancer-associated fibroblasts. In all assays, we demonstrated the tumor target specificity of TEG A3, lysing tumor cells within 48 h. Our study demonstrates the utility of complex 3D cytotoxicity assay model systems incorporating the tumor microenvironment in the functional evaluation of T cell–based adoptive immunotherapy, providing a useful platform for early-stage preclinical development of immunotherapies.

This note is motivated by recent studies by Eriksson-Bique and Soultanis about the construction of charts in general metric measure spaces. We analyze their construction and provide an alternative and simpler proof of the fact that these charts exist on sets of finite Hausdorff dimension. The observation made here offers also some simplification about the study of the relation between the reference measure and the charts in the setting of

A category $\mathcal{O}$ for oriented matroids
Authors: Kowalenko Ethan , Mautner Carl
Published: June 2023

We associate to a sufficiently generic oriented matroid program and choice of linear system of parameters a finite-dimensional algebra, whose representation theory is analogous to blocks of Bernstein—Gelfand—Gelfand category

\mathcal{O}

. When the data above comes from a generic linear program for a hyperplane arrangement, we recover the algebra defined by Braden—Licata—Proudfoot—Webster.

Applying our construction to non-linear oriented matroid programs provides a large new class of algebras. For Euclidean oriented matroid programs, the resulting algebras are quasi-hereditary and Koszul, as in the linear setting. In the non-Euclidean case, we obtain algebras that are not quasi-hereditary and not known to be Koszul, but still have a natural class of standard modules and satisfy numerical analogues of quasi-heredity and Koszulity on the level of graded Grothendieck groups.
Technological transformation of the bone at the Eneolithic tell settlement of Vitănești, southern Romania (Gumelnița B1 level)
Authors: Mărgărit Monica , Moldoveanu Katia , Bălășescu Adrian , Torcică Ion , Mirea Pavel
Published: June 2023

This paper discusses the technological exploitation of bone at the tell settlement of Vitanesti (southern Romania). A total of 307 artefacts from the Gumelnita B1 level were analysed for this study, which can be assigned to four product and sub-product categories (waste, blanks, preforms, finished pieces). At the level of determined bones, the most numerous are those belonging to large species, both domestic and wild mammals. We also note the use of bones belonging to species rarely found in the Eneolithic bone industry (Bos primigenius, Equus ferus, Canis familiaris) in the Lower Danube. At the typological level, bevelled tools predominate, along with pointed tools and projectile points. A varied range of other typological categories includes spatulas, abraded astragalus, spindle whorls, burins, needles, and figurines, among others. The large quantity of preforms proves that the production of the assemblage was carried out in situ. It is an interesting assemblage which proves that the bone pieces were involved in various activities within the Vitanesti community that lived at the end of the 5th millennium BC, from the processing of hides or vegetable fibres to hunting. This assemblage could serve as a reference for future studies, as there are not many comparable assemblages for the same period in Southern Romania.
Becoming a research university as a strategic choice in Bahir Dar university፡ A resource dependency perspective
Authors: Getahun Koye Kassa , Reda Nigusse Weldemariam , Wube Abeba Seyoum
Published: June 2023

This paper explored how the need for research universities in Ethiopia is justified, practiced, and could be improved using the strategic tactics of the resource dependency perspective. Bahir Dar University (hereafter referred to as BDU) was taken as a case to understand the need for a research university and its practices. Document analysis was used as a source of data. Consequently, an analysis of various institutional and national secondary sources revealed that the existing uncertainties related to critical resources motivated Bahir Dar University to devise a strategic choice of becoming a research university. The uncertainties are justified in terms of economic, political and institutional conditions. Although the university envisioned becoming a research university by 2025, the existing institutional and national conditions seem to be immature to sustain the necessary resources and conditions that a research university requires. As a result, following the higher education differentiation effort, BDU had to revise its vision and extend the possible time its vision could be realized to 2030. It is concluded that the need for BDU to become a research university seems to be challenging and needs much effort to be realized. Hence, institutional re-arrangements following the strategic tactics of the resource dependency perspective need to be devised to realize the strategic choice of becoming a research university.

Published: June 2023

Background: In the production of instant pepper powder, some manufacturers add adulterants to the pepper powder.
Objective: This study aimed to detect the presence of corn added in instant white pepper products in the market.  
Method: The TLC Fingerprint analysis was used. Fingerprints were made using white pepper from three regions in Indonesia: Tasikmalaya, Kalimantan, and Bangka. The corn used as the adulterant came from three regions in Indonesia: West Java, Central Java, and Kalimantan. Extraction was carried out using the maceration method, where 96% ethanol was used as the solvent. TLC patterns were made and visualised under UV light at 254 nm and 366 nm. Chromatogram analysis was performed.    
Result: Loading PC-2 against PC-1 in PCA with an eigen value of 931.54 indicated the loading score of white pepper was clustered in quadrants 2 and 3, while that of the corn adulterant in quadrants 1 and 4. 
Discussion:The sample projection on the PCA system used showed that samples A and C are distributed between quadrants 1-2 and 3-4, while sample B is distributed in quadrant 2.     
Conclusion: Based on the loading results of PC-2 against PC-1, samples A and C contained corn adulterants, while sample B contained other adulterants.
THE EFFECT OF USING ALUMINIUM FOAM IN STEEL SANDWICH TARGETS AGAINST BLUNT PROJECTILES
Authors: Abdelshafy Mohamed Hassan
Published: June 2023

In this paper, the effect of using Aluminium Foam (Alporas) on the ballistic resistance of multi layered target comprising two steel layers and Al foam in between against rigid projectile of blunt nose impact at sub-ordnance velocities (320 : 400 m/s) is evaluated using finite element analysis using ABAQUS/explicit. Rigid projectile of blunt nose is considered, it is manufactured from Arne tool steel with a nominal mass and diameter of 197 g and 20 mm. The evaluation has been done by comparing the ballistic resistance of a single layer of steel plate to eleven different composite plate structure comprising two layers of steel plates and Aluminium foam layer sandwiched between them. The study reveals that using Aluminium foam absorbs more kinetic energy from the projectile during penetration and, hence, reduces the residual velocity of the projectile. Also it is found that the total mass of each structure is less than the total mass of single layer target.

A PREVENTIVE APPROACH USING THE DATA MINING OF TRANSACTION AUDIT LOG FOR DATABASE INTRUSION DETECTION
Authors: Rathod Yagnik
Published: June 2023

Information is a key component in today’s global business environment. An organization, institute, or business firm uses various database management systems for managing its crucial information. The security mechanism provides by DBMS is not enough to prevent intruders or detect anomalous behavior. Unauthorized users and sometimes authorized users to execute malicious commands intentionally or by mistake, cannot be detected and prevented by a typical security mechanism. Intrusion detection system finds intrusive action and attempts by detecting the behavior of user’s action. Security features can be enhanced by adding intrusive detection technology to the Database management system. Data mining is to identify valid, novel, potentially useful, and ultimately understandable patterns in massive data. It is required to apply data mining techniques to detect various intrusions. In this paper mechanism based on data mining is discussed to detect malicious action in DBMS.

Authors: Okpara Uwho Kingsley , Nyebuchi Amadi Hachimenum , Chikezie Okechi
Published: June 2023

The most vexing problem plaguing Rumuomoi's 11kV distribution network is voltage sag and swell, which degrades power quality. There has been no effective mitigation control implemented. The purpose of this research is to address the issue of power quality by implementing artificial neural network (ANN) control with an embedded dynamic voltage restorer (DVR). To begin, the artificial neural network is trained using the input and desired data obtained during simulation using a proportional integral (PI) controller. To limit the amount of data obtained during training, the Levenberg-Marquardt feed forward back method is utilized, and the result for each iteration is determined in Matlab software. The desired dynamic voltage restorer system was tested using a replicated model of Rumuomoi 11kV and it was determined that Bus 7 is 0.938p.u, Bus 8 is 0.9244p.u, Bus 9 is 0.9148p.u, Bus 10 is 0.9035p.u, Bus 11 is 0.8912p.u, and Bus 12 is 0.8811p.u, all of which exceeded the statutory limit condition of 0.95-1.01p.u. There were no bus voltage violations after network optimization with DVR, demonstrating that DVR is effective at enhancing power quality by removing voltage sag and swell in the distribution network.

Published: June 2023

Heavy metal contents in soil from Onda tantalite mining area were studied. Thirty and ten soil samples were collected from the mining area and control site, respectively, using a hand auger. The soil samples were analysed for heavy metals; Cd, Co, Cr, Cu, Fe, Pb, Mn, Ni and Zn using atomic absorption spectrophotometer, AAS. The results obtained showed that the mean concentrations for the respective metals above were 9.38±2.98, 18.25±5.32, 40.29±8.47, 34.40±8.77, 1590.57±403.46, 53.10±11.65, 188.57±41.13, ND and 620.44±91.47 mg/kg in soils from the mining area and 6.40±1.99, 21.00±3.68, ND, 36.36±5.26, 1195.95±314.52, 31.24±6.93, 143.23±28.26, ND and 564.15±120.82 mg/kg for soils from the control site. The mean metal contents from the mining site were all higher than those from the control site due to mining activities, except for Co and Cu but were all lower compared to the recommended permissible limits by WHO except for Cd and Zn. The EF, CF, PLI, ERI and PERI evaluated for metals from the mining site show no imminent danger. However, there is the need for constant and regular monitoring of the level of heavy metals in soil from the site because of accumulation overtime, and soil remediation should be employed to take care of cadmium and zinc.

Published: June 2023

The simulation of railway systems plays a key role in the design of the supply of the railway network but also in the functionality of the train itself. Various studies have been carried out to understand the railway network and by extension the operation of the trains. [1,2] The history of the railway is an everlasting history of speed. The rail mode is a guided and low grip transit mechanism. Since the beginning of the Industrial Revolution at the start of the 19th century, when rail first emerged in Europe, passenger train speed has been crucial for competition—not necessarily with other kinds of transportation, but with other rail firms. Additionally, it gave verifiable proof of technological advancement in the time's most developed nations. In this work, an approach is studied for the modeling and simulation using Anylogic PLE regarding saving the energy and the distance traveled for five distinct time periods.

Published: June 2023

India has large proven reserve of coal but most of the coal has large quantity of ash. Utilization of this high ash content coal is again a verychallenging task. Presently, gasification of high ash coals has not yet been in application due to the difficulties arising from the ash handlingprocesses. In this work an attempt was made to design a partially fluidized bed reactor that can handle 30 kg/hr coal as a feedstock. By usingan appropriate design procedure a complete design of a hybrid gasifier was studied deeply. The major aim of present research is todetermine the air flow rate for proper gasification, reactor diameter and reactor height, feed particle diameter, nozzle orientation and numbernozzles, reduction zone diameter and height. Experiments were carried out with feeding rate of 9.8 kg/hr with high ash content coal having39.83% ash. Satisfactory results have been found during experiments. The average producer gas generation during trial run was found to be29.8 Nm3/hr while average calorific value of producer gas was about 4500 kJ/Nm3. The work described here favours us understand the realgasification process for high ash content coal and thus facilitates the industrial application of gasification technology.
Rammed Earth Construction Using Cement & Coir Fibers

Published: June 2023

The paper aims to investigate the geotechnical and mechanical properties of rammed earth blocks by analyzing their compressive and tensile strength, density, and durability, while taking into account the effects of coir elongation and cement content. The specific aspects that were analyzed in the study are as follows:a) Effect of coir % & elongation on OMC and MDD, b) Effect on Consistency of sample, c) Combined effect of cement and coir on compressive strength, d) Combined effect of cement and coir on tensile strength. The objective of this investigation is to determine the optimum value of stabilizer for rammed earth blocks that will improve their geotechnical and mechanical properties while also fulfilling the principles of sustainability. The experiment used 8% cement as a stabilizer and 8% coir as reinforcement in lengths ranging from 20 mm to 40 mm.  Based on the results of the experiment, it was found that the characteristic dry compressive strength of the rammed earth blocks improves up to 1% coir of 20 mm length, and then gradually decreases as the length and percentage of coir increase. In addition, the strength ratio drops by about 3.05%–6.27% as the coir length increases from 20 mm to 40 mm.These results suggest that the optimum value of coir reinforcement for improving the mechanical properties of rammed earth blocks is 1% with a length of 20 mm. However, it is important to note that the sustainability of the technique should also be considered when determining the optimum value of stabilizer and reinforcement.  Overall, the investigation demonstrates that the use of coir reinforcement along with cement stabilization can be an effective approach for improving the geotechnical and mechanical properties of rammed earth blocks. However, further research is needed to optimize the coir percentage and length to achieve the desired strength properties while ensuring sustainability.

RAFA: Redundancies-assisted Algebraic Fault Analysis and its implementation on SPN block ciphers
Authors: Qiu Zehong (Zephyr) , Zhang Fan , Feng Tianxiang , Gong Xue
Published: June 2023

Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA). The effectiveness of AFA on lightweight block ciphers has been demonstrated. However, the complexity of the algebraic systems prevents it from attacking heavyweight block ciphers efficiently. In this paper, we propose a novel cryptanalysis called Redundancies-assisted Algebraic Fault Analysis (RAFA) to facilitate the solution of algebraic systems in the setting of heavyweight block ciphers. The core idea of RAFA is to expedite SAT solvers by modifying the algebraic systems, which is accomplished via two methods. The first method introduces redundant constraints, which is proposed for the first time in the context of algebraic cryptanalysis. The second one is a sophisticated linearization of the nonlinear Algebraic Normal Form (ANF). It takes RAFA for about 9.68 hours to attack AES-128. To the best of our knowledge, this is the first work that uses a general SAT solver to attack AES with only a single injection of byte-fault. Moreover, RAFA can attack AES-128 in 50.92 and 27.54 minutes for nibble- and bit-based fault model, respectively. In comparison, the traditional DFA algorithm implemented by pure C takes 4 ~ 5 hours under all three fault models investigated in this work. Moreover, in order to show the generality of RAFA, we also apply it to other heavyweight block ciphers. The best results show that RAFA could recover the key of Serpent-256 and SPEEDY-r-192 in 20.7 and 1.5 hours using only three faults, respectively. In comparison, AFA could not break these two ciphers even when 30 bits and 50 bits of their keys are known, respectively. Furthermore, no DFA work on Serpent or SPEEDY is known using comparable fault models.

Metacognition knowledge can significantly measure students' critical thinking skills, especially in solving problems. The ability to solve problems serves as a bridge among metacognition as well as educational success. This study aims to determine metacognitive knowledge on the ability to solve complex problems in social geography. The sample of the research sample were 163 divided into two control and experimental groups. The experimental class used online project-based learning, and the control group used conventional learning. The instrument used to collect the metacognitive data uses was learning and Study Strategies Inventory (LASSI) adapted to the characteristics of students. By 77 items of LASSI were 48 items were valid and reliable used in this study. The result showed that the experimental group using online project-based learning had better metacognitive knowledge, especially on variables that had significant differences of p < 0.05, such as Information Processing, Attitude, Motivation, Self-Testing and Aids Studies. Furthermore, differences in the ability to solve complex problems of social geography are discussed in this study.

Education has an important role in determining the development and self-realization of individuals. Therefore, the teaching and learning process is essentially centered on one issue, namely how teachers implement a classroom management system in an effective teaching and learning process in order to achieve a goal. This study aims to determine the Application of Classroom Management by School Teachers in the Perspective of Structural Functional Theory. The research method used is library research, then analyzed and presented the data findings objectively. The results showed that the application of classroom management in the structural-functional theory was reflected through the role of the group controlled by the classroom teacher. The role of the existing group is expected to meet and satisfy the needs of both teachers and students in the classroom, this will familiarize the needs and interests and bring the expectations of the members closer. Classroom management systems must complement, maintain and improve both individual motivation and the cultural patterns that create and sustain motivation.

The scramble method can help students understand history learning material easily, but not many teachers have implemented it in history learning. The purpose of this research was to find the effect of the scramble method in history learning to increase students' interest in learning history. The quantitative method used is a quasi-experimental non-equivalent control group design and divides the class into two groups, namely experimental and control. This study used a population of class X SMA students in Ambon, with a total sample of 104. The sampling technique used cluster sampling, and data collection used observations, interviews, and instruments. In analysing the test data, the independent sample t-test and the N-gain score test were used to see changes. The results showed that the scramble method in learning had a good influence on increasing students' interest in learning history as evidenced by the independent sample t-test test with a significance value of 0.000 0.05, and the N-gain score test which was included in the medium criteria. The scramble method in history learning is an innovation applied by history teachers so that learning objectives are achieved so that history learning will be more meaningful.

Industrial apprenticeship experience has not been realized optimally towards student work readiness. So that the process of factualization and comparing theoretical knowledge with actual situations and conditions in the world of work becomes less than optimal. In addition, students' work motivation to be ready to work is still in the low category. This study aims to reveal the effect of internship experience and work motivation on work readiness. The sampling technique used simple random sampling and obtained research respondents as many as 450 students in 5 vocational education schools in Yogyakarta. The combination of factor analysis and regression analysis was used to analyze the data using second-order PLS-SEM analysis. Convergent and discriminant validity, and internal consistency reliability has met the test requirements. Evaluation of the structural model shows the value of effect size (f2) with a large effect, the determination coefficient (R2) of the variable is 65.90%, and the predictive relevance (Q2) is 51.10%. Hypothesis testing is based on the Î²-coefficient, Ï-value, dan T-statistic values that have met the cut-off values suggested in the literature. So that all hypotheses Ha is accepted which indicates that there is a positive and significant effect on the internship experience and motivation on student work readiness. Schools are expected to provide encouragement for work motivation and review the apprenticeship process from planning to implementation in the field so as to increase student work readiness.

Character education needs to be adequately integrated into classroom instruction. One method of implementing character education is using appropriate learning media and models. This study was conducted to describe the effect of qualitatively applying the Lampung folklore book â€œThe Legend of Tulung Nagaâ€ and the Value Clarification Technique (VCT) model in learning. The method used in this research is Single Subject Rate (SSR). The design of this study used A (baseline-1), B (intervention 1), A (baseline-2), and B (intervention 2). Based on the study results, the student's character developed after applying the Value Clarification Technique (VCT) model and Lampung folklore books in learning. This development can be seen in each stage of the research in stages A (baseline-1), B (intervention 1), A (baseline-2), and B (intervention 2). Based on observations and questionnaires, there is a strengthening of a religious character, nationalism, independence, cooperation, and integrity in students after reading Lampung folklore books and learning with the Value Clarification Technique (VCT) model. Based on the findings, it is possible to conclude that using story books in conjunction with the Value Clarification Technique model improves character education. This study adds knowledge about using the VCT model with learning material like legend storybooks to enhance students' character values.

In the past, English was considered the language of non-Islamic religions but now English is believed to be the language for international communication for academic and 'dakwah' purposes. However, students of Islamic universities and institutes may have various purposes for learning English. This is because young scholars may have not seen the real need to study English outside the campus and this is not introduced by their teachers when they study at high schools. This study is aimed at describing the main purposes of learning English as a foreign language perceived by the students of Islamic Institutes and Universities in Indonesia. Seven hundred and fourteen undergraduate students from three different Islamic institutes were involved in this study. The finding shows that the primary objective of students learning English at these three institutions is to serve as a conduit for promoting the faith of Islam and to be able to convey Islamic teachings on a larger (international) basis Furthermore, these students stated that their religious goal in learning English was to be able to improve their English language skills while also receiving a lot of Islamic knowledge, even in the form of English material delivered concretely.
