Lecturers are expected to cope with stress in their workplace in order to continue to be productive. The demand to fulfill targets will increase the incidence of occupational stress. The aim of the study was to determine the factors associated with occupational stress among state university lecturers in Bandung, Indonesia. The study was carried out on 354 state university lecturers in Bandung, who came to the research location during May 2017. It was conducted by means of a diagnostic survey with the use of the Self Reporting Questionnaire (SRQ), Spiritual Wellness Inventory-R (SWI-R), Social Readjustment Rating Scale (SRRS), Miller Smith lifestyle assessment inventory, and Occupational Stress Scale (OSC). A total of 330 respondents became our study subjects with response rate of 92.94%. A correlation bivariate was applied to analyse the correlation of external and internal factors with occupational stress. The statistical analysis was conducted by means of SPSS Statistics 18.0 with p≤0.05. From 330 lecturers, there were 153 (46.4%) males and 177 (53.6%) females. The marital status included 257 (77.9%) married, 27 (8.2%) single, while 46 (13.9%) did not answer. The results proved the existence of a correlation between life, stress event, life style, mental emotional disorders, with occupational stress. The spirituality factors contributed to occupational stress were selfworth, control, and connectedness. Lecturer had to cope with occupational stress. There are some factors, which could influence occupational stress among lecturers.
Poly (p-phenylene vinylene) (PPV) was synthesized from p-xylylene bis(tetrahydrothiophenium chloride) using the Wessling route and characterized by Fourier Transform Infra-Red (FTIR) and UV-visible (UV-VIS) spectroscopic techniques. The significance of thermal treatment along with evolution of precursor polymer to polymer PPV was also studied through these spectroscopic techniques. Thermally Stimulated Current (TSC) measurements indicated the presence of crystallization, sulphonium group which occurred through the evolution from precursor polymer to polymer PPV during thermal treatment.
The radiation-response characteristics of polymetharylic acid gel dosimeter prepared with different concentrations of monomer and cross-linker is described in these studies. The dosimeters were prepared under the hypoxic condition in a glove box and were then irradiated with gamma-rays produced by Co-60 radionuclide that was generated at 1.25MeV energy. The irradiation took place at different doses ranged from 0Gy to 19Gy. Due to the radiation activities, chain-reaction polymerisation processes had taken place in the formation of polymethacrylic acid (PMAA) gel, which cause the dose response mechanism increased in the NMR relaxation rates of protons. It has been observed that for higher concentration of monomer and cross-linker, the polymerization rate was increased.
The aim of this work was to study radiation and the effects of temperature on conductivity properties of polyvinyl alcohol (PVA)-based potassium hydroxide (KOH) and propylene carbonate (PC), where the ionic conduction preferentially occurs in the amorphous phase by free radicals ions through gamma-irradiation. Alkaline composite polymer electrolyte (ACPE) consisting of PVA, KOH and PC of different concentration ratios were prepared by solvent-casting technique. The ACPE were irradiated with different doses from 5 kGy up to 200 kGy. The conductivity properties of the electrolyte films were measured at different frequencies in the range 20 Hz to 1 MHz using LCR meter. The results showed that the conductivity properties were dependent on the radiation dose, temperature and the concentration of the polymer blends.
