HUBUNGAN KARAKTERISTIK PEKERJA, JARAK MONITOR DAN PENCAHAYAAN DENGAN KELUHAN SUBJEKTIF KELELAHAN MATA PADA OPERATOR DI CENTRAL CONTROL ROOM PT SEMEN PADANG TAHUN 2014
No full textOperator memiliki risiko mengalami kelelahan mata karena terus-menerus bekerja
dengan monitor. Survai pendahuluan menunjukan sebagian besar operator di Central
Control Room PT Semen Padang mengalami kelelahan mata. Tujuan dari penelitian
ini adalah mengetahui hubungan antara karakteristik pekerja, jarak monitor dan
pencahayaan dengan keluhan subjektif kelelahan mata pada operator di Central
Control Room PT Semen Padang Tahun 2014.
Metode
Desain penelitian kuantitatif dengan pendekatan cross sectional, dilakukan di
Central Control Room PT Semen Padang bulan September 2014 sampai Januari
2015. Variabel yang diteliti adalah usia, istirahat mata, lama kerja, kelainan refraksi,
jarak monitor dan pencahayaan terhadap keluhan subjektif kelelahan mata. Jumlah
sampel 40 orang. Pengumpulan data menggunakan kuesioner. Analisis data secara
univariat dan bivariat dengan 95% CI (α=0,05).
Hasil
Hasil analisis didapatkan 67,5% operator mengalami keluhan subjektif kelelahan
mata, 52,5% berusia tua, 55% masa kerja lama, 82,5% tidak mengistirahatkan mata,
52,5% mengalami kelainan refraksi, 67,5% jarak monitor baik, 75% intensitas
pencahayaan tidak memenuhi syarat. Variabel yang memiliki hubungan yang
bermakna adalah umur dan kelainan refraksi.
Kesimpulan
Lebih dari separuh operator berusia tua, masa kerja lama, tidak mengistirahatkan
mata, mengalami kelainan refraksi dan intensitas pencahayaan tidak memenuhi
syarat. Terdapat hubungan yang bermakna antara umur dan kelainan refraksi dengan
keluhan subjektif kelelahan mata. Diharapkan perusahaan melakukan pemeriksaan
mata secara berkala pada pekerja yang bekerja dengan komputer, penyuluhan dan
pemasangan poster tentang ergonomi komputer, dan meningkatkan intensitas
pencahayaan

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
