  • This study was conducted to investigate the effects of $Megazone^{(R)}$ (a mineral mix) supplementation on growth performance, nutrients digestibility, blood characteristics, meat quality and carcass traits in weaning-to-finishing pigs. A total of 48 crossbred $(Landrace{\times}Yorkshire{\times}Duroc)$ pigs with initial body weight (BW) of $4.46{\pm}0.18kg$ were used in a 21 wks trial. Pigs were blocked by weight and allotted to two dietary treatments in a completly randomized design. There were 6 pens per treatment. Dietary treatments included: 1) Control (CON: basal diet) and 2) MT (basal diet+0.8% $Megazone^{(R)}$). Through the entire experimental period, there were no effects of dietary $Megazone^{(R)}$ supplementation on growth performance nutrients digestibility, blood characteristics and meat quality traits (p>0.05). Market weight and backfat thickness also had no differences between the two treatments (p>0.05). However, carcass weight and carcass ratio in MT treatment were improved significantly compared with CON treatment (p<0.05). In conclusion, supplmentation of $Megazone^{(R)}$ can increase carcass weight and carcass ratio in weaning-to-finishing pigs, however, it has no effects on growth performance, nutrients digestibility, blood characteristics and meat quality traits.

  • In spite of the socio-economic benefits of the construction industry, it accounts for many deaths, injuries and illnesses in many countries. In developing countries like Vietnam, the situation is even worse. Health and safety (H&S) management plays a crucial role in the efforts to improve H&S performance as it contributes to mitigating the risks of occupational injuries and illnesses. However, within the wider H&S literature in Vietnam, there is no insight into the current state of affairs of H&S management, particularly in terms of the management practices that need attention in order to improve H&S management across the construction sector. This study therefore presents the findings of an inquiry into the H&S management practices of contractors in Vietnam. The study employed a questionnaire survey which yielded 58 responses from contractors, particularly those operating in Southern Vietnam. Some commonly implemented H&S management practices by the contractors are: provision of personal protective equipment (94%), allocation of H&S supervisor on site (90%), and displaying of company H&S policy on construction sites, company website, and head/branch offices (86%). Some of the less implemented practices are: networking/engaging with other companies/institutions (e.g. government offices) about H&S issues (39%), rewarding workers for safe work behaviour (39%), reviewing and updating H&S plans (48%), and displaying regulatory H&S posters on site (45%). The findings have provided some insight into the current state of affairs of the H&S management practices of contractors in Southern Vietnam and could thus inform efforts by industry stakeholders to improve the aspects of H&S management that are lagging.

  • In this paper, an embedded micro processor based resistance spot welding controller is introduced which has been recently developed by Hyosung Co. Ltd. The performance of rapid and constant high current control is tested experimentally. This paper shows configurations of measuring system for high current and realtime RMS conversion techniques of sampled discrete data. A digital proportional control is adopted for this system and the result shows that this new product is working well at wide range of welding current and the performance is improved compared with some other commercially available controllers that are widely used in our industries. User friendly MMI system and a computer network system to monitor each welding processes are also presented.
