Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.

This study investigated factors that influence public school speech-language pathologists' acceptance and/or resistance to computer technology. Significant differences were found between speech-language pathologists who are frequent users of computers in the workplace and those who seldom or never use them. These differences were attributed to differences in attitudes toward computers, available funding for computers, in-service training, and physical facilities.

Advances in computer technology have created opportunities for the development of a multimedia situational test in which responses are filmed with a webcam. This paper examined the relationship of a so-called webcam test with personality, cognitive ability, job experience, and academic performance. Data were collected among 153 psychology students. In line with our expectations, scores on the webcam test, intended to measure interpersonally oriented leadership, were related to extraversion, conscientiousness, emotional stability, and job experience. Furthermore, the webcam tests significantly predicted students’ learning activities during group meetings over and above a cognitive ability test and a personality questionnaire. Overall, this study demonstrates that webcam tests can be a valid complement to traditional predictors in selection contexts.

Abstract The internet can be made as a way to transfer knowledge from lecturers to students, while Learning that utilizes the internet is one of the E-Learning Learning media. E-learning is distance learning that utilizes computer technology or computer networks or the Internet E-learning, so that it can enable the learning process through computers in their respective places without having to physically go to attend classes or lectures in class, Systems e-learning learning is a new way of teaching and learning. E-learning as a special learning media PAI courses provide a very important role and a large function in the course because so far there are many shortcomings and weaknesses such as the limitations of space and time in the teaching and learning process through E-learning which prioritizes the efficiency of learning so students get full teaching even though they do not have to be face to face, can also be accessed anywhere, anytime, according to the assignments given by the lecturer usually scheduled with a specified deadline. The development of education towards e-learning is a must so that the quality standards of education can be improved, E-learning is one of the uses of internet technology in the delivery of learning and its broad reach. E-learning can also be an answer to a health problem that is Pandemic Corona (Covid-19) which is very influential also in every aspect of life, especially in education.Keywords: Effectiveness, Utilization, Islamic Religious Education, E-Learning, Covid 19. Abstrak Internet dapat dijadikan cara untuk mentransfer ilmu pengetahuan dari Dosen kepada mahasiswa/mahasiswi. Adapun Pembelajaran yang memanfaatkan internet salah satunya adalah media pembelajaran E-Learning. E-learning adalah pembelajaran jarak jauh (distance learning) yang memanfaatkan  teknologi komputer atau jaringan komputer atau internet E-learning, sehingga dapat  memungkinkan proses pembelajaran melalui komputer di tempat mereka  masing– masing tanpa harus secara fisik  pergi  mengikuti pelajaran atau pun  perkuliahan di kelas,  Sistem pembelajaran e-learning adalah cara baru dalam proses belajar mengajar. E-learning  sebagai   media pembelajaran khususnya mata kuliah PAI memberikan  peran   sangat   penting  dan fungsi yang besar pada mata kuliah tersebut karena selama  ini terdapat banyak  kekurangan  dan kelemahan seperti keterbatasan ruang dan waktu dalam  proses belajar  mengajar melalui E-learning yang  mengedepankan keefisienan dalam belajar sehingga  mahasiswa mendapat pengajaran yang penuh meski tidak harus bertatap muka, juga bisa di akses di mana saja, kapan saja,  sesuai dengan tugas yang diberikan oleh dosen biasanya terjadwal dengan  batas  waktu  yang  di tentukan. Pengembangan  pendidikan menuju e-learning merupakan suatu keharusan agar standar mutu pendidikan dapat ditingkatkan,  E-learning merupakan salah satu penggunaan teknologi internet dalam penyampaian  pembelajaran  serta  jangkauannya yang luas. E-learning  juga dapat menjadi jawaban dari suatu permasalahan kesehatan yaitu Pandemi Corona (Covid-19) ini yang sangat berpengaruh juga pada setiap aspek kehidupan terutama bidang pendidikan.Kata kunci  :  Keefektifitas, Pemanfaatan, Pendidikan Agama Islam,  E-Learning, Covid 19.
