Abstract

This paper presents a process technique developed for Thin Film Pattern generation using Photolithography&Wet Chemical Etching on two sides of substrate using Direct Lithography system for use in Thin Film Microwave Integrated Circuits (MICs). Pattern generation on two sides of the substrate is essential where the circuit involves Micro strip to Slotline transition and also where interconnections are required between two circuits positioned back-to-back in a trendy approach to achieve better performance and improved reliability. Direct Lithography is adopted for generation of critical Photo masks or Patterns directly on metallized substrates obviating the need of photo masks. Direct Patterning on substrates has the advantage of fine feature size and fast turn-around time. A method of pattern generation on two sides of the substrate is developed. Details on development of process technique are presented in the paper.

Abstract

The aim of the present study was to compare merchant navy officers on their Quality of sleep and Quality of life. The study was conducted on 300 merchant navy officers with 150 Deck and 150 Engine officers. For this purpose, Pittsburgh Sleep Quality Index (PSQI) by Buysse et al. (1988) and WHO Quality of Life-BREF (WHOQOL-BREF, 1994) were used. Descriptive statistics, Mann Whitney U test and 2×2 ANOVA were used to analyse the data. The results showed that Deck officers were found to be low on quality of life and quality of sleep in comparison to engine officers.

Abstract

The aim of the present study is to compare merchant navy officers on their Job satisfaction. Subjective well-being and Stress. The study was conducted on 300 merchant navy officers having 150 Deck and 150 Engine officers. For this purpose Generic Job satisfaction Scale (Macdonald & MacIntrye, 1997); Positive affect and Negative affect (Watson et al., 1988); satisfaction with life scale (Diener et al., 1985); and Perceived stress scale (Cohen et al., 1983) were used. Descriptive statistics and 2×2 ANOVA was used to analyse the data. The results show that Deck officers were found to be low on job satisfaction and subjective well-being, high on stress in comparison to engine officers.
