Human Factors Analysis

With the advent of voting machines and computers, the voting process has evolved into a complex man-machine system. However, to date no comprehensive human factors analysis of the voting process has been conducted. A systems analysis of the voting process yielded four major functions which impact critically on voter behavior and performance: (a) Design of voting instructions (b) Display of crucial voting information (c) Human engineering of voting equipment and procedures (d) Distribution of voting machines and personnel across and within voting districts. Some critical aspects of each area are discussed, and some additional points of interest to human factors specialists interested in researching this area are mentioned.

Kajian ini mengkaji ciri kerja dan prestasi profesional Teknologi Maklumat di Unit/Bahagian Perkhidmatan Maklumat sektor awam Malaysia. Ciri kerja dianalisis melalui Model Ciri Kerja oleh Hackman dan Oldham. Prestasi kerja pula dianalisis berpandukan Borang Pengenalpastian Perlakuan yang dipermudahkan, asalnya dibina oleh Botterbusch pada tahun 1985. Hubungan ciri kerja dengan prestasi diselidiki menggunakan ujian Mann–Whitney U. Ciri kerja menunjukkan tahap tinggi dalam kepentingan tugas dan keperluan bekerjasama dalam menjalankan tugas tetapi dengan tahap rendah dalam autoriti tugas. Prestasi kerja yang tinggi ialah dalam produktiviti dan perlakuan sosial dan yang rendah pula dalam tabiat/sikap kerja. Kajian ini mendapati terdapat hubungan bererti antara ciri kerja dan prestasi di kalangan profesional Teknologi Maklumat sektor awam Malaysia. Kata kunci: Ciri kerja; prestasi kerja; teknologi maklumat; sektor awam This study analyzed job characteristics and performance of Information Technology professionals at the Information Technology centers of the public sector of Malaysia. Job characteristics were analyzed based on the Job Characteristics Model by Hackman and Oldham. Performance on the other hand was analyzed using a simplified Behavior Identification Form, originally developed by Butterbusch in 1985. The relationship between job characteristic and performance was determined using the Mann–Whitney U test. Job characteristics showed a high score on job significance and dealing with others but low on task authority. Job performance showed high productivity and high social behavior but low on work habit and attitudes. This research found that there is a significant relationship between job characteristics and performance of Information Technology professionals of the Malaysian public sector departments. Key words: Job characteristics; job performance; information technology; public sector departments

Coupling Components

The paper took a structure improvement of a coupling component for board-level photoelectric interconnection and analyzed its coupling efficiency by stimulation. Firstly, it briefly introduced the commonly used coupling components, analyzed the coupling performance, and selected a coupling component to improve its structure. Secondly, it introduced methods to improve coupling components, such as 45-degree gold-plated cross section, and manufacturing ball lens on both the top and the bottom to increase the coupling efficiency of coupling components. Finally, the optical simulation software Advanced Systems Analysis Program was applied to analyze the coupling efficiency. The coupling efficiency of improved coupling component was increased. The analyses and results are significant in engineering application and guiding.

SUMMARYThe performance of a series of intervarietal F1 hybrid populations was determined in simulated swards in a range of environmental conditions. On average the hybrids were more stable in performance than their parental varieties, but they showed no general yield advantage. Several hybrids were markedly heterotic at the higher-parental level, however. More heterosis was exhibited in high productivity conditions than in less favourable environments. A generally poor correlation between parental and F1 hybrid performance under competitive simulated-sward conditions and performance in noncompetitive spaced-plant conditions was found.
