Bahasa di dunia sangat beragam, tetapi dimungkinkan adanya persamaan. Sebagai pelajar, sangat penting untuk mempelajari fonologi dan fonetik dari berbagai  bahasa untuk membandingkan dan menyamakan satu dengan yang lainnya. Bahasa Inggris dan Arab sama-sama memiliki struktur linguistik terbesar dari semua bahasa di dunia. Kedua bahasa tersebut memiliki kesamaan ciri, seperti konsonannya. Dari persamaan tersebut, Lestiono dan Gusdian (2017) melakukan penelitian terhadap konsonan bahasa Arab dalam membantu pengucapan bahasa Inggris, yang dikenal sebagai tabel kosonan bahasa Inggris-Hijaiyah. Tujuan dari penelitian ini adalah untuk mengetahui pengucapan dari delapan anggota paduan suara universitas dalam menyanyikan lagu-lagu bahasa Inggris sebelum dan sesudah pengenalan konsonan Hijaiyah sebagai mediasi. Dalam penelitian ini digunakan studi kasus, yang termasuk dalam desain kualitatif yang digunakan dalam mencapai pengucapan yang dibangun oleh subjek penelitian melalui observasi, analisis, dan deskripsi. Objek penelitian ini adalah bunyi konsonan yang dihasilkan oleh peserta penelitian saat menyanyikan lagu “When I Sing” oleh Russel Robinson dan Charolette Lee dan “The Seal Lullaby” oleh Eric Whitacre dan Rudyard Kipling. Instrumen yang digunakan adalah dokumen analisis. Dalam analisis ditemukan adanya partisipan yang salah dalam mengucapkan kosa kata yang ditargetkan sebelum diperkenalkan dengan konsonan Hijaiyah. Setelah pengenalan konsonan Hijaiyah sebagian besar peserta terdengar akurat. Hal ini dapat disimpulkan bahwa konsonan Hijaiyah dapat memfasilitasi anggota paduan suara mahasiswa untuk belajar dan menghasilkan kata-kata bahasa Inggris yang akurat saat bernyanyi.    Language in the universe is various; however, it does not close the possibility that each languages have an equation. As a learner, it is crucial to learn the phonology and phonetics of some languages to compare and equalize one another. English and Arabic both have the biggest linguistic construction. Both languages have the sameness of characteristics such as some of their consonants. From those similarities, Lestiono and Gusdian (2017) conducted a study on Arabic Consonant sounds to arrive at English Pronunciation, known as English-Hijaiyah consonant corresponding chart. The objective of the current research is to discover the pronunciation of eight university choir members in singing English songs before and after the introduction of Hijaiyah consonants as the mediation. In this present study acquire a case study, which is included to qualitative design that was used in arriving at the pronunciation constructed by the research subjects through observation, analyzation, and description.. The research objects were the consonant sounds produced by research participants while singing “When I sing” by Russel Robinson and Charolette Lee and 'The Seal Lullaby” by Eric Whitacre and Rudyard Kipling. The instrument was document analysis. In the findings, participants mispronounced  many of the targetted words before they were introduced to Hijaiyah consonants as the mediation . Whereas, the pronunciation after the introduction showed that most of the participants sounded correct. This can be concluded that Hijaiyah consonants can facilitate the university student choir members to learn and produce accurate English words while singing.

This chapter describes a mixed-method, multiple case study that examined ways in which synchronous educational Twitter chats were used, first, to enhance graduate and undergraduate university student learning, second, to build professional networks, and third, to provide a loosely regulated means to achieving self-determined professional development goals. Findings suggest that while difficult at the onset, participation in Twitter educational chats was an enhancement to students' overall course learning experience. Specifically, university students' use of chats for educators helped them achieve social presence in this virtual environment, as well as to better understand the connections between positive student-teacher relationships and K12 student learning. Included are recommendations for use of Twitter synchronous educational chats in the college classroom as well as future directions in research.

The purpose of this study is to design the Visual Display Terminal parameters for the visual comfort and high performance. Taguchis Design of Experiments method was used to determine the optimum level of parameters that consist of external and internal lighthing, monitor position angle and eye-to-monitor distance. An experimental study was conducted in Ergonomics laboratory. Typing operation was done as a case study. 15 university student (7 males and 8 females) with age rangebetween 21-26 old took participation.The results of study findsthat the optimum external lighting (A1) = 1325 Lux, the monitor eye position angle (B2) = 15 o, The distance vision from eye - monitor (C1) = 20 inches, internal lighting (D1) = 60 Lux. This study has also found that eyesblinking decrease about 50% and the performance increase about 89.76%.Thus, the parameters of VDT can produce better visual comfort and performance.

In an increasingly mobile world, transience is becoming the norm. Sustainable community food initiatives, therefore, must organise to withstand high turnover of volunteers. Using a case study of the United Kingdom’s National Union of Students’ food growing scheme in universities, this paper aims to map the causes and effects of short-term, irregular, and low participation using a causal loop diagram to understand how to mitigate their negative impacts and improve participation. Data was gathered through interviews, workshops, photovoice, a fishbowl discussion, and a reflective diary. We found three amplifying feedback loops increasing short-term, irregular and low participation, their causes, and their impacts. These feedback loops were precariously buffered by a continuous in-flow of new potential participants each academic year. We also found that the stakeholders of these gardens conceptualised time akin to both temporary and permanent organisations, and these differing conceptualisations were a source of tension. Furthermore, although ‘organisational amnesia’ was a problem, the gardens were still learningful spaces. We recommend both upstream and downstream solutions are implemented to buffer the impacts of transience and suggest that university and students’ union staff could play a crucial and subtle supporting role.

This paper presents advantages and disadvantages of Raman spectroscopy when used for testing banknotes, i.e. in case study I, 1 and 5 dinars banknotes from a private collection dating from 1876 of numismatic value were analyzed, and in case study II, 1000 dinars banknote from circulation together with its counterfeit. In both cases banknotes were analyzed by using Raman spectrometer DXR Raman microscope at the Faculty of Physical Chemistry, with a laser of wave-length 780 nm at 12 mW of power. Specters were recorded under microscope using 50X lens in a range 1800-60 cm-1. Analyses from case study I on both specimens showed spectrum characteristic for fluorescence appearance, therefore intensive signal of fluorescence covered Raman signal. In case study II, it was established that Raman spectroscopy can reliably detect a counterfeit banknote. Research, comparisons and analyses regarding original and counterfeit 1000 dinars note were performed on red banknote surfaces.
