Poultry output value in Taiwan takes a large proportion of whole livestock production. However, in 2014, it was suffered from a serious bird flu invasion in Taiwan, culling a large number of poultries. Take geese as an example, almost 90% of the geese were culled in 2014. As a result, it caused serious losses to livestock industry. In order to prevent outbreak of bird flu, the government has stipulated that poultry houses must be rebuilt as non-open poultry houses and rehabilitated. Therefore, the development of the design in closed poultry houses is important. In this study, Computational Fluid Dynamics (CFD) was used to simulate a 30 m ^* 8.5 m ^* 3.6 m closed poultry house. There are two suction fans used for longitudinal ventilation. Through the different circulation fan setups to evaluate for the growth conditions of poultry and improve the ventilation of closed poultry houses, and reduce the possibility of invasion of pathogenic sources at the same time. The results showed when a circulation fan was not placed, there was a phenomenon of non-uniform airflow distribution within 6 m near water-cooled wall. When a circulation fan was placed 3 m away from the water-cooled wall, some parts of the airflow concentrated near the fan and caused non-uniform airflow distribution within 9 m near the water-cooled wall, which may be unsuitable for poultries living. The study showed that simulation of flow field facilitates designs of non-open poultry houses.

Pineapples are not only nutritious, but also have significant economic importance in Taiwan. Traditional technique used to determine the fruit’s quality is by hitting the fruit with palm. However, such method requires experience and is highly dependent on the condition of the fruit. More importantly, decisions made are often subjective. This research used near infrared spectroscopy to develop a fast and non-destructive method to measure the quality of pineapples. Tai-Nung No. 17 pineapple was used in this research to construct the calibration equation. During the experiments, pineapple samples are separated into three sections: top, middle, and bottom. Optical measurements are taken around each section in 90 degree increments, with a total of 131 samples. A multivariate model was then established by mathematical pre-treatments and modified partial least squared regression. Results showed strong correlation between constituents and optical spectrum, with a coefficient of determination r_c²=0.78,r_p²=0.747,SEP=1.142°Brix,RPD=1.803. Future experiment aims to increase the predictability of spectrum model by enhancing experimental methods, increasing sample size as well as minimizing experimental error.

Magnolol, a hydroxylated biphenyl agent isolatedfrom herbal planet Magnolia officinalis, is a componentof traditional Asian herbal teas. It has been reported tohave anti-microbial, anti-inflammatory, and anti-canceractivity. Non-small cell lung cancer (NSCLC) cell lines(A549, H441 and H520) and normal human bronchialepithelial cells (HBECs) were used to evaluate the cytotoxiceffect of magnolol. We show that magnolol inhibitedcellular proliferation, increased DNA fragmentation, anddecreased mitochondrial membrane potential in all NSCLCcells, but had no cytotoxic effect on HBECs. Magnololtriggered the release of pro-apoptotic proteins: Bid, Bax and cytochrome c from mitochondria, but did not activatethe caspase-3, -8, and -9, suggesting that magnolol inducesapoptosis of NSCLC cell lines via a caspase-independentpathway. The caspase-independent pathway is mediatedthrough the activation of nuclear translocation of apoptosis-inducing factor, endonuclease G and cleaved poly(-ADP-ribose) polymerase, which played important roles inmediating cell death. Furthermore, magnolol inhibitedPI3K/AKT and ERK1/2 activity, but up-regulated p38 andJNK activity in A549 cell lines. The results of this studyprovided a basis for understanding and developing magnololas a novel treatment of NSCLC.

Taiwan's domestic development of incubators are in simple structure, at low prices, and generally used by the industry. However, high number of regional dead eggs, the inability to understand the environmental conditions of incubator and other issues occurred frequently, resulting in operation and production difficulties. This research developed a wireless environmental monitoring system to collect data and upload to the cloud. A variety of environmental sensors and Raspberry Pi 3 were used in the establishment of wireless sensing module and environmental information detection platform. The environmental information was displayed in real-time and uploaded to the cloud. Computational fluid dynamics (CFD) was also used to simulate the internal flow field inside the incubator to determine the environmental control features, and control heating and humidification equipment with a PID controller. In this study, the establishment of wireless environmental monitoring system was completed. The wireless sensing module and the environment information detection platform have also been developed and tested. The stability of wireless sensing module was 98.5%, and the CFD simulation error was under 20%, which was low enough to predict the actual field temperature changes, and can be applied to the regulation of the incubator environment.
