IntroductionThe extensive availability of the internet has led to the recognition of problematic usage of the internet (PUI) or so called internet addiction (IA), probably mostly involving adolescents.AimHere we present a study focusing on the incidence and consequences (including burnout, which is relatively rarely studied) of internet addiction among high school students using a questionnaire-based non-random sampling cross-sectional survey. Included questionnaires were the Problematic Internet Use Questionnaire, the Maslach Burnout Inventory General Survey for Students MBI-GS (S), the 9-item short version of Beck Depression Inventory (BDI-SF), the Athens Insomnia Questionnaire and the EQ-5D (quality of life) questionnaire. Data were evaluated the exertion of Student’s t-test, chi square test and Pearson’s rank-order correlation. Logistic regression analysis was used to determine the significance of the different parameters as independently associated with PUI.ResultsOverall 3,000 paper-based questionnaires were successfully delivered and 2,540 responses received (response rate of 84.6%). 1,309 males (mean age 17.6 ± 1.43 years) (51.5%) and 1,231 females (mean age 17.5 ± 1.4 years) (48.5%) took part in our study. Problematic usage of the internet was detected in 486 (19.1%) students (232 males, mean age 17.6 ± 1.35 years and 254 females, mean age 17.34 ± 1.37 years). In a logistic regression analysis sleep disturbance (OR: 1.84, 95% CI: 1.83–2.03), depression (OR: 1.97, 95% CI: 1.77–2.02) and burnout (OR: 1.8, 95% CI: 1.16–1.94) were significantly associated with PUI.ConclusionNearly one fifth of our study population suffered from PUI, which was strongly associated with school burnout, insomnia and depression, which underlines the importance of this phenomenon.

IntroductionAutistic children experience sleep disturbances at a higher rate than do neurotypical children. It has been argued that sleep disturbances negatively impact behavior, exacerbate learning difficulties, and decrease the quality of life among autistic children. Increasing exercise has been proposed to address sleep disturbances, however, little is known about how exercise might best be promoted for autistic children in Aotearoa New Zealand. Here, we explored caregivers' lived experiences of their autistic child's sleep disturbances and participation in exercise.MethodsSemi-structured interviews were conducted with 15 mothers of autistic children aged between 5 and 10. Mothers also completed the Sleep Disturbances Scale for Children (SDSC).ResultsScores on the SDSC indicated that there was considerable variation in sleep disturbance severity. Eight themes were identified from the interviews: sleep disturbances, the impact of exercise on sleep, exercise activities, whānau involvement in exercise, barriers for participation in exercise, support for participation in exercise, sensory considerations for participation in exercise, and activities specifically for children with special needs.ConclusionsOur findings highlight how challenging sleep disturbances can be for autistic children and their families and how participation in exercise can be promoted to potentially minimize their negative impact.

The present work was performed to evaluate the levels of phytochemical constituents and the antioxidant and antibacterial properties of marine red seaweed (Kappaphycus alvarezii) and seagrass (Cymodocea serrulata). Quantitative phytochemical analysis, antioxidant activity and antimicrobial activity against five potential pathogenic bacteria was investigated. In each case, we found the presence of flavonoids, tannins, phenolic compounds, glycosides, steroids, carbohydrates and ashes. Alkaloids were only found in K. alvarezii, though they were not found in C. serrulata. The antimicrobial properties of both K. alvarezii and C. serrulata chloroform extracts were found to be antagonistically effective against the Gram-positive bacteria Bacillus subtilis and the Gram-negative bacteria Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio harveyi and Klebsiella pneumoniae. GC-MS analysis revealed the presence of 94 bioactive compounds in K. alvarezii and 104 bioactive compounds in C. serrulata, including phenol, decane, dodecane, hexadecane, vanillin, heptadecane, diphenylamine, benzophenone, octadecanoic acid, dotriaconate, benzene, phytol, butanoic acid and 2-hydroxyl-ethyl ether, which all played important roles in antioxidant and antibacterial activities. Thus, in view of the results, both K. alvarezii and C. serrulata could be considered to be sources of ingredients with appreciable nutritional and medicinal value.

Abstract
The gap states near the conduction band edge (E
C) in the vicinity of the interface between Mg-ion-implanted GaN and Al2O3 deposited after post-implantation annealing were investigated in the range between E
C – 0.15 eV and E
C – 0.45 eV. For this purpose, capacitance–voltage measurements were performed on MOS diodes with the n-type conduction of Mg-implanted GaN maintained by suppressing the dose. Although the gap state density D
T was reduced for the sample prepared with the dose of 1.5 × 1012 cm–2 by conventional rapid thermal annealing (RTA) at 1250 °C for 1 min using an AlN protective cap layer, further improvement was achieved by capless ultra-high-pressure annealing (UHPA) at the same temperature for the same duration. Furthermore, the D
T distributions for the samples with capless UHPA at 1400 °C for 5 min are comparable to that for the sample with conventional RTA at 1250 °C for 1 min using the cap layer.

Published: July 2023

Abstract
In this investigation, plasma ion nitriding was conducted to improve the hardness, wear resistance, and hydrogen embrittlement resistance of aluminum alloys. To research the surface characteristics and hydrogen embrittlement resistance of the nitrided layer, indentation experiments, scratch experiments, friction experiments, FE-SEM, XRD, EDS, and 3D laser microscopic analyses were conducted. An AlN layer was observed on the surface after plasma ion nitriding. As a results of the indentation experiment, hardness (H
IT) of the nitrided layer decreased from 1370 to 749 MPa and 538 MPa, respectively with hydrogen embrittlement for 3 h and 6 h. As a result of hydrogen embrittlement, adhesion force between the base material and nitrided layer tended to decrease from 6.54 to 2.50 N. In addition, as a results of the friction experiment, the section where the nitrided layer was maintained was shortened as the hydrogen embrittlement time increased.
Sayyid Muhammad al-Hassani al-Baghdadi and his approach to writing history
Authors: العزاوي علاوي , مرضي كرار 
Published: July 2023

Al-Saied Mohammed Al-Hasani Al-Baghdadi interpreted history in a philosophical jurisprudential way according to his pure religious culture. In addition, the works and readings from which we drew Al-Baghdadi view to history studied the history from a religious point of view in particular. He skipped out any work related to the origins of western history of all tendencies and schools. Accordingly, we comprehended that his views came to support our interest and understanding of our Islamic heritage in general and our Shiite heritage in particular. This does not imply that Al-Baghdadi adopts a methodological view to history more than an attempt to rewrite and correct the view to Islamic history in general. His purpose of theses attempts is to make the Islamic history related to the historical reality of the Islamic cause with all its stages and periods. By that he is confirming basic cases concerning the nature and purpose of this history on one hand and method of dealing with the Islamic historical records on the other hand which then became the base of our understanding of this history.
The proof is with Abi Al-Barakat Al-Baghdadi

Praise be to God alone the Lord of Worlds, Prayer and peace be upon His Prophet and his pure Ahlul-Bait.
Abi Al- Barakat Al-Baghdady occupied a n important position in the history of our Arab Islamic philosophy, he had an original critic ability to which we can hardly find a peer. He comprehended all the different intellectual trends of his period, this is exhibited clearly in his ( Al-Mo`atabar fi Al-Hikmah ) where he put his philosophical project and critical attitude towards his period intellectual trends , this book had considered all the tiny details of these trends and directions, we can say that it is the intellectual encyclopedia of Abi Al- Barakat Al-Baghdady period.
Throughout this research, it became clear that Abi Al- Barakat was able to establish the bases of the rational critical method in his ( Al-Mo`atabar fi Al-Hikmah ), this indicates the originality and deepness of this philosopher thought, just like the other Muslim philosophers such as Al-Gazzaly , Averroes and other.
The researchers has many reasons to choose this subject such as :- what had been published for Abi Al- Barakat is only a small part of his works , he still in need for more and more of the deep study, a number of the researchers had studied his works before, yet the field of logic is still unstudied, as I believe, hence I decided to study this subject.
The thesis is divided into three chapters , an introduction and a conclusion.
The first chapter is a an introductory approach for Abi Al- Barakat Al-Baghdady, it includes the philosopher`s life and works as well as his philosophical method, within the first topic, while the second topic deals with Logic before Abi Al- Barakat Al-Baghdady which is represented by the Greek philosophers, with a brief exhibition for Aristotle Logic, and the Logic for the Philosophers of Islam.

Translation of Culture-Specific Terms from Arabic into English Between Loss and Preservation
Authors: Makaoui Ismail 
Published: July 2023

Undoubtedly, translation is one of the oldest means of communication and a bridge connecting various cultures. In this sense, it stands as an effective tool for intercultural communication. Be it through written literary works or media outlets, translation is unarguably listed as one of the best communication channels. Thus, the present paper tackles the problematic issue that translators encounter while translating some culture-specific words or expressions from Arabic into English. A huge gap between the SL and TL may lead to more difficulties to transfer the message. The difference between Arabic and English in linguistic structures and discrepancies in their cultures sometimes make the process of translation a real challenge. Translation, of course, is not an easy task, but it requires a skilled and knowledgeable translator to make it right. In this paper, the primary concern is to shed light on the issue of culturally-specific terms that may generate obstacles for the translator, as well as to see to what extent these obstacles may affect the translation process. Certain translation strategies and methods that are proposed by some theorists are also addressed as remedy solutions for highly challenging culture-specific words or expressions following the model of Newmark (1988) and Aixela (1996). The paper concluded that possessing a cultural background of the source text can be extremely useful in cases of cultural-complexity translation.
