Opis:: An ergonomic assessment of the involvement of static muscular forces like back strength, grip strength and pinch strength in different occupations was made. A study was conducted on 45 normal adult males (15 subjects per group) which included video display terminal (VDT) operators, industrial workers and safety inspectors. Their maximum back strength, handgrip strength and pinch strength were measured with dynamometers. The observed values of back strength were significantly lower in VDT operators while significantly higher in safety inspectors and moderate in industrial workers. The values of grip strength and pinch strength of all sample groups were more or less similar. The findings clearly indicate that static muscular strength varies significantly in different occupations. Heavy static muscular load might lead to an accumulation of metabolic waste and toxins on the back resulting in lower back strength in VDT operators and industrial workers.

Opis:: Visual and auditory simple reaction times for both right and left hands of young university male students were recorded with a simple reaction timer, before and after an exercise schedule without and with elevated temperatures in a climatic chamber. The results indicated a decrease in both visual and auditory reaction times after the exercise, but a marked increase in them was noticed when exercise was performed at elevated temperatures. The difference in reaction times in preferred and nonpreferred hands was negligible at rest, i.e., without any exercise and elevated temperature. However, the difference was significant when exercise was performed at elevated temperatures. Visual reaction time was longer than auditory reaction time in all conditions. The results suggest that in hot industries, increased temperature has a specific rather than general effect on cognitive processes, perception and attentiveness, leading to increased chances of human errors, fatal accidents and loss of productivity.

Opis:: The paper studies economic determinants of sectorial level (Extractive sector, manufacturing and assembly sector, infrastructure sector and service sector) foreign direct investment (FDI) to six ASEAN countries (Malaysia, Indonesia, Singapore, Thailand, Vietnam and Philippine). The study covers over a period of sixteen years, from 2001 to 2016, by employing static panel data model. This study includes inflation, gross domestic product growth, government expenditure on education, electric power consumption, exchange rate, trade openness and lending interest rate as economic variables. These factors are based on their relative importance from previous empirical literature. Overall findings reveal that there is a mix result in terms of key determinants of sectorial level inward FDI which proves that FDI is not a single phenomenon and that each sector must be treated on its own terms to attract FDI into the country.
W artykule przedstawiono uwarunkowania gospodarcze na poziomie sektorowym (sektor wydobywczy, sektor produkcji i montażu, sektor infrastruktury i sektor usług) bezpośrednich inwestycji zagranicznych (BIZ) dla sześciu krajów ASEAN (Malezja, Indonezja, Singapur, Tajlandia, Wietnam i Filipiny). Badanie obejmuje okres szesnastu lat, od 2001 do 2016 r., poprzez zastosowanie statycznego modelu danych panelowych. Badanie to obejmuje inflację, wzrost produktu krajowego brutto, wydatki rządowe na edukację, zużycie energii elektrycznej, kurs walutowy, otwartość handlową i oprocentowanie kredytu jako zmienne ekonomiczne. Czynniki te opierają się na ich względnej wadze z poprzedniej literatury empirycznej. Ogólne wyniki wskazują, że istnieje mieszany wynik pod względem kluczowych czynników wpływających na napływ BIZ na poziomie sektorowym, co dowodzi, że bezpośrednie inwestycje zagraniczne nie są pojedynczym zjawiskiem i że każdy sektor musi być traktowany na własnych warunkach w celu przyciągnięcia bezpośrednich inwestycji zagranicznych do tego kraju.

Opis:: The pea seeds were exposed to full-wave rectified sinusoidal magnetic fields. The effects of electromagnetic treatment on seedling growth and chlorophyll contents and have been investigated. Seed were sown after magnetic field treatment according to ISTA under controlled laboratory conditions. The magnetic filed treatment of seeds increased the growth significantly (P<0.05), while the increment in contents of chlorophyll have been found non significant (P<0.05). The shoot length, root length, root dry mass, shoot dry mass, fresh root mass and fresh shoot mass increased up to 140.5, 218.2, and 104, 263.6, 74.5, 91.3%, respectively. The result suggested that magnetic field could be used to enhance the growth in pea plant.

Opis:: The present investigation was conducted to appraise the physiochemical adjustments in contrasting maize cultivars, namely, PakAfgoi (tolerant) and EV-5098 (sensitive) subjected to heat shock. Seven-day-old seedlings were exposed to heat shock for different time intervals (1, 3, 6, 24, 48 and 72 h) and data for various physiochemical attributes determined to appraise time course changes in maize. After 72 h of heat shock, the plants were grown under normal conditions for 5 d and data for different growth attributes and photosynthetic pigments recorded. Exposure to heat shock reduced growth and photosynthetic pigments in maize cultivars. The plants exposed to heat shock for up to 3 h recovered growth and photosynthetic pigments when stress was relieved. A time course rise in the relative membrane permeability, hydrogen peroxide (H2O2) and malondialdehyde contents was recorded particularly in the EV-5098 indicating that heat shock-induced oxidative stress. Activities of different enzymatic antioxidants greatly altered due to heat shock. For instance, an increase in superoxide dismutase activity was recorded in both maize cultivars. The activity of ascorbate peroxidase was greater in Pak-Afgoi. However, the peroxidase and catalase activities were higher in plants of EV-5098. Heat shock caused a significant rise in the proline and decline in the total free amino acids. Overall, the performance of Pak-Afgoi was better in terms of having lesser oxidative damage and greater cellular levels of proline. The results suggested that oxidative stress indicators (relative membrane permeability, H2O2 and malondialdehyde) and proline can be used as markers for heat shock tolerant plants.

Opis:: Seed pre-sowing magnetic field treatment was reported to induce biochemical and physiological changes. In the present study, response surface methodology was used for deduction of optimal magnetic field doses. Improved growth and yield responses in the pea cultivar were achieved using a rotatable central composite design and multivariate data analysis. The growth parameters such as root and shoot fresh masses and lengths as well as yield were enhanced at a certain magnetic field level. The chlorophyll contents were also enhanced significantly vs. the control. The low magnetic field strength for longer duration of exposure/ high strength for shorter exposure were found to be optimal points for maximum responses in root fresh mass, chlorophyll ‘a’ contents, and green pod yield/plant, respectively and a similar trend was observed for other measured parameters. The results indicate that the magnetic field pre-sowing seed treatment can be used practically to enhance the growth and yield in pea cultivar and response surface methodology was found an efficient experimental tool for optimization of the treatment level to obtain maximum response of interest.

Opis:: Plastic is one of the main pollutant sources that are difficult to decompose and then carried into the ocean and fragmented into smaller parts (microplastics) due to UV radiation and water currents. Their small size means that microplastics are often ingested by aquatic organisms, such as fish. This research aimed to determine the presence, abundance, and types of microplastics in the digestive tract of four dominant fishes landed at Lengkong Fish Auction Point, Cilacap, Central Java, i.e. threadfin (Eleutheronema tetradactylum), mackerel (Rastrelliger sp.), threadfin bream (Nemipterus japonicus), and hairtail (Trichiurus lepturus). We found microplastics in the digestive tract of four selected fishes with a frequency of occurrence of 100%. The concentration of microplastics in fish digestive tracts is relatively high, with a value range of 12 ±2.86 to 28.33 ±8.11 particles∙ind.-1. Microplastics were found in films, fibres, fragments, and granule shape types with various colours: brown, purple, blue, black, green, transparent, and yellow. The polymers found were polystyrene (PS), nylon, acrylonitrile butadiene styrene (ABS), polyurethane (PU), polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). The present study provides baseline data for microplastics contamination in commercial fish species landed at Lengkong Fish Auction Point, Cilacap, Central Java, Indonesia. The fact that we discovered PU, the most harmful polymer, piques our attention.
