  • This paper presents the findings of a visiting scholarship research that was carried out at the Faculty of Engineering, University of Technology Sydney, Australia. Based on the extensive literature review, government databases and international statistics, it introduces an analytical framework for comparison of the national innovation systems (NIS) of China and Australia in regards to their strengths and weaknesses. This is done through individual examination and comparison of functions of typical institutions involved in innovation to reveal the structural characteristics and performances of the two systems. The interactions among these institutions are then analysed to illustrate their dynamics and efficiency. The comparison has shown clearly that China's NIS has several weaknesses and gaps due to its developing and transition stage. There are positive signs that Chinese Government has recognised the nature and scope of the problem and seems to work in the right direction. This paper aims to support this process by providing some recommendations that could help bridge the gaps between the NISs of China and Australia. Due to the fact that both, China's and Australia's NISs, have their unique characteristics but share numerous complementary features, there is a large potential for further cooperation between the two national innovation systems.

  • With a purpose to set up an efficient national security system for both at war-time and peace-time, President Lee's government transferred the emergency management function from the Office of Prime Minister to Ministry of Public Administration and Security (MOPAS). As a result national emergency management system has been changed into diversified management system ; the function of comprehensive disaster control, emergency preparation to MOPAS, fire, civil defense and disaster management to NEMA and anti-terrorism to NIS, which produce another inefficiency. For this reason, this research presents desirable improvement alternatives through scrutinizing current governmental function and structure.

  • Class I and class II MHC genes have been identified in most of the jawed vertebrate taxa. In all investigated bony fish species, unlike mammals, the classical class I and class II MHC genes are not linked and even are found on different chromosomes. Linking and clustering of the class I and class II MHC genes is not the only phenomenon clearly detected in the evolution of immune system from cartilaginous to mammals. In all non-mammalian classes the LMP/TAP genes are highly conserved within class I genes region, while these genes are conserved within class II genes region only in mammals. Today we know that LMP/TAP genes in mammals have a crucial role in peptide processing for presentation within class I molecules, as well as in anti-tumor immunity. For these reasons, differences in clustering of LMP/TAP/MHC genes can be responsible for the differences in mechanisms and efficacy of anti-tumor immunity in non-mammalian vertebrates compared to same mechanisms in mammals. Also, the differences in cytokine network and anti-tumor antigens presentation within classes of vertebrates can be explained by toe peculiarity of LMP/TAP/MHC gene clustering.

  • Microbial biofilms are resilient, immune-evasive, often antibiotic-resistant health challenges, and increasingly the target for research into novel therapeutic strategies. We evaluated the effects of a nutraceutical enzyme and botanical blend (NEBB) on established biofilm. Five microbial strains with known implications in chronic human illnesses were tested: Candida albicans, Staphylococcus aureus, Staphylococcus simulans (coagulase-negative, penicillin-resistant), Borrelia burgdorferi, and Pseudomonas aeruginosa. The strains were allowed to form biofilm in vitro. Biofilm cultures were treated with NEBB containing enzymes targeted at lipids, proteins, and sugars, also containing the mucolytic compound N-acetyl cysteine, along with antimicrobial extracts from cranberry, berberine, rosemary, and peppermint. The post-treatment biofilm mass was evaluated by crystal-violet staining, and metabolic activity was measured using the MTT assay. Average biofilm mass and metabolic activity for NEBB-treated biofilms were compared to the average of untreated control cultures. Treatment of established biofilm with NEBB resulted in biofilm-disruption, involving significant reductions in biofilm mass and metabolic activity for Candida and both Staphylococcus species. For B. burgdorferi, we observed reduced biofilm mass, but the remaining residual biofilm showed a mild increase in metabolic activity, suggesting a shift from metabolically quiescent, treatment-resistant persister forms of B. burgdorferi to a more active form, potentially more recognizable by the host immune system. For P. aeruginosa, low doses of NEBB significantly reduced biofilm mass and metabolic activity while higher doses of NEBB increased biofilm mass and metabolic activity. The results suggest that targeted nutraceutical support may help disrupt biofilm communities, offering new facets for integrative combinational treatment strategies.

  • This study was conducted to evaluate the effects of dietary addition of sucrose, propylene glycol and Tween 80 (Polysorbate 80 : Non-ionic Surfactants) on pre-partum (21 d) and post-partum (21 d) nutrients intake, blood metabolites, occurrence of metabolic disorders, milk yield and its composition in Holstein cows. Two basal diets were formulated each for pre- and post-partum period. The diets were mixed daily and fed at ad libitum to transitional cows. Forty cows of similar parity and milk yield were randomly divided into four groups (ten animals in each). The cows in three groups were supplemented either with 280g of sucrose/day (SU), SU+64g propylene glycol/day (SUP) or SUP+50g Tween80/day (SUPT). The feed for the fourth group was not supplemented and this group served as control (C). Pre-partum DM, total digestible nutrients (TDN), and crude protein (CP) intake was similar in cows fed C, SU, SUP, and SUPT diets. Post-partum DM, TDN, and CP intakes were the highest with SUPT diet followed by SU, SUP and control diets. Pre-partum blood non-esterified fatty acids (NEFA) concentration was noticed significantly higher in cows fed control diet compared to those fed SU, SUP and SUPT diets. The concentration of NEFA was similar at calving and during post-partum period across cows fed different experimental diets. Blood glucose and Ca concentration during pre- and post-partum periods were not significantly different in cows fed C, SU, SUP and SUPT diets. Milk yield (kg/day) was similar in cows fed different experimental diets. However, milk fat percent and 4% fat corrected milk yield were higher in cows fed SU diet (p<0.05) followed by SUP, SUPT and C diets. One case of ketosis was recorded in cows fed control diet however its occurrence was not observed in cows fed other diets. Occurrence of retained placenta and mastitis was numerically higher in cows fed control diet compared with those fed SU, SUP and SUPT diets. In conclusion, the NIS and propylene glycol feeding along with sucrose could improve the 4% fat corrected milk and fat yield in early lactating cows with significant reduction in NEFA and metabolic disorders during transitional period.

  • An experiment was conducted to investigate the effects of environmentally friendly agents (yucca extract, mineral feed additive, acidifier, nonspecific immunostimulating anionic alkali solution) on the growth performance, nutrient digestibility, nutrient excretion and carcass characteristics in growing-finishing pigs. A total of 125 pigs were allotted into 5 treatments with 5 replications, 5 pigs per pen in a completely randomized block design. Dietary treatments consisted of 1) control: basal diet, 2) YE: basal diet+120 mg/kg of yucca extract, 3) MFA: basal diet+50 mg/kg of mineral feed additive, 4) NIS: basal diet+3% of NIS (nonspecific immunostimulating anionic alkali solution), and 5) Acidifier: basal diet+0.5% of acidifier (organic acid complex). During the growing phase of the feeding trial, There were no significant differences in average daily feed intake (ADFI) and feed conversion ratio (F/G) among treatments, but the Acidifier group showed higher average daily gain (ADG) than the MFA group (p<0.05). During the finishing phase, there were no significant differences in growth performance among treatments, however YE supplementation increased ADG and F/G by 3.1 and 6.15%, respectively, when compared to control group. Proximate nutrients (dry matter, DM; crude protein, CP; crude ash, CA; crude fat, CF; gross energy, GE; calcium, Ca and phosphorus, P) digestibility did not show any significant differences among the treatments. And there were no significant differences in DM, N and P excretion as well. The supplementation of environmentally friendly agents tended to increase carcass weight compared to control group. Pigs fed MFA showed significantly heavier (p<0.05) carcass weight than those fed control or Acidifier diets. Addition of these agents except for NIS to diet for growing-finishing pigs caused a similar feed cost/kg weight gain than control group. Therefore, present study suggested that the optimum environmentally friendly agent would be yucca extracts, considering the effects on growth performance, nutrient digestibility, nutrient excretion, carcass characteristics and feed cost in growing-finishing pigs.

  • This study was conducted to improve the quality of National Health Policy by analysing the effects of sociodemographic characteristics, Medical institutions characteristics and characteristics of Admission-Discharge on the length of stay in hospital for schizophrenic patients from the data of Health Insurance Review & Assessment Service. The subjects were 4,692 patients who were diagnosed with schizophrenia as main diagnosis from the data records of HIRA-NIS 2016. Regression analysis was performed to evaluate the effect on the length of stay. Sociodemographic characteristics, hospital characteristics and characteristics of Admission-Discharge were used as explanatory variables and length of stay in hospital was used as a dependent variable. The result of study showed that female, age, medical aid, the kind of hospital, gangweon-do and with mental disease were found to be the factors that affect the length of stay. The significance of this study is to use the public data for evaluating factors that affect the length of stay in hospital for schizophrenic patients. But this study did not consider disease severity, so further study is needed for evaluation of the effects of factors on the length of stay according to disease severity.

  • The interaction between ocean and ice shelf is a critical physical process in relation to water mass transformations and ice shelf melting/freezing at the ocean-ice interface. However, it remains challenging to thoroughly understand the process due to a lack of observational data with respect to ice shelf cavities. This is the first study to simulate the variability and circulation of water mass both overlying the continental shelf and underneath an ice shelf and an ice tongue in the Terra Nova Bay (TNB), East Antarctica. To explore the properties of water mass and circulation patterns in the TNB and the corresponding effects on sub ice shelf basal melting, we explicitly incorporate the dynamic-thermodynamic processes acting on the ice shelf in the Regional Ocean Modeling System. The simulated water mass formation and circulation in the TNB region agree well with previous studies. The model results show that the TNB circulation is dominated by the geostrophic currents driven by lateral density gradients induced by the releasing of brine or freshwater at the polynya of the TNB. Meanwhile, the circulation dynamics in the cavity under the Nansen Ice shelf (NIS) are different from those in the TNB. The gravity-driven bottom current induced by High Salinity Shelf Water (HSSW) formed at the TNB polynya flows towards the grounding line, and the buoyance-driven flow associated with glacial meltwater generated by the HSSW emerges from the cavity along the ice base. Both current systems compose the thermohaline overturning circulation in the NIS cavity. This study estimates the NIS basal melting rate to be 0.98 m/a, which is comparable to the previously observed melt rate. However, the melting rate shows a significant variation in space and time.
