  • Pre-slaughter conditions affect poultry meat quality. Therefore, stresses before slaughter like heat stress, struggle and shackling on the shackle line, crating and transport and feed withdrawal are very important for the poultry industry in respect of quality as well as welfare of the birds. However, exposure to heat in oxidative stress can in turn lead to cytotoxicity in meat type birds. Chickens exposed to heat stress before slaughter showed the lowest ultimate pH and birds shackled for a longer time the highest. The abdominal fat content was higher in heat stressed birds. Struggling on the shackle line hastened the initial rate of the pH drop and increased the redness of breast meat. Again, with increasing struggling activity, lactate concentration in breast muscle of chicken increased. Paler meat was found in birds that were transported for a longer time than in those after a small journey or not transported. The pre-slaughter and eviscerated weights were decreased as the length of feed withdrawal period increased.

  • Metaverse services generate text data, data of ubiquitous computing, in real-time to analyze user emotions. Analysis of user emotions is an important task in metaverse services. This study aims to classify user sentiments using deep learning and pre-trained language models based on the transformer structure. Previous studies collected data from a single platform, whereas the current study incorporated the review data as "Metaverse" keyword from the YouTube and Google Play Store platforms for general utilization. As a result, the Bidirectional Encoder Representations from Transformers (BERT) and Robustly optimized BERT approach (RoBERTa) models using the soft voting mechanism achieved a highest accuracy of 88.57%. In addition, the area under the curve (AUC) score of the ensemble model comprising RoBERTa, BERT, and A Lite BERT (ALBERT) was 0.9458. The results demonstrate that the ensemble combined with the RoBERTa model exhibits good performance. Therefore, the RoBERTa model can be applied on platforms that provide metaverse services. The findings contribute to the advancement of natural language processing techniques in metaverse services, which are increasingly important in digital platforms and virtual environments. Overall, this study provides empirical evidence that sentiment analysis using deep learning and pre-trained language models is a promising approach to improving user experiences in metaverse services.

  • Acute myocardial infarction (AMI) is a major cause of morbidity and mortality in the Asia-Pacific region, and mortality rates differ between countries in the region. Systems of care have been shown to play a major role in determining AMI outcomes, and this review aims to highlight pre-hospital and in-hospital system deficiencies and suggest possible improvements to enhance quality of care, focusing on Korea, Japan, Singapore and Malaysia as representative countries. Time to first medical contact can be shortened by improving patient awareness of AMI symptoms and the need to activate emergency medical services (EMS), as well as by developing robust, well-coordinated and centralized EMS systems. Additionally, performing and transmitting pre-hospital electrocardiograms, algorithmically identifying patients with high risk AMI and developing hospital networks that appropriately divert such patients to percutaneous coronary intervention-capable hospitals have been shown to be beneficial. Within the hospital environment, developing and following clinical practice guidelines ensures that treatment plans can be standardised, whilst integrated care pathways can aid in coordinating care within the healthcare institution and can guide care even after discharge. Prescription of guideline directed medical therapy for secondary prevention and patient compliance to medications can be further optimised. Finally, the authors advocate for the establishment of more regional, national and international AMI registries for the formal collection of data to facilitate audit and clinical improvement.

  • The objective of this study is to analyze the types and current status of development projects that underwent environment assessment in recent three years and provide basic data to encourage environment-friendly development projects in the future. This study was conducted by analyzing the pre-environment review reports and environment impact statements of development projects that took place in Gyeonggi province. Key findings are as follows. First, a total of 2,465 development projects spanning $173km^2$ were undertaken in Gyeonggi province in recent three years. This is equivalent to three times of the area of Anyang city. Second, types of development projects were in the order of factories and industrial parks, road construction, town (housing estates) development, sports facilities and waste treatment facilities. Public projects accounted for about 30%, while private investment projects represented 70%, indicating that private sector projects were as twice as high. The findings of this study show that the development density of Gyeonggi-do should be examined as a whole in order to develop a comprehensive, long-term plan and harmonize conservation and development systematically in Gyeonggi-do in a holistic perspective.

  • The Red shirts came to attract attention of the international community during April to May in 2010 by successfully organizing explosive popular demonstrations. The momentum was the military coup on September 9, 2006. The Red color was chosen amid movements against the new constitution instituted under the military junta. In discourse struggles, the Red shirts compared their resistance against the Democratic Party government lead by Abhisit Vejjajiva to that of phrai (commoner or serfs) against ammart (aristocrats or bureaucrats) under the pre-modern reign of sakdina. The Red shirts strongly accused Prem Tinsulanonda, the chief of the Privy Council, of being a mastermind of 2006 military coup, who symbolically represents the cohesion between the palace and the military. It has constituted an unprecedented defiance towards national taboo where the trinity of Nation, Religion, and King has been consecrated. The objective of this article is to review the Red Shirts' ideology, organizations and activities in terms of the modernized phrai's struggles for expanding counter-hegemony. While Antonio Gramsci focused on why socialist revolution had failed to materialize in capitalist Western Europe, I pay attention to why political liberalism has failed to wash away pre-modernity and take root in capitalist Thailand, applying the Gramscian concept of hegemony by contrasting 'hybrid ammart' with 'modernized phrai'.

  • Based on ASME probabilistic risk assessment (PRA) and NEI PRA peer review guidance, we evaluate a human reliability analysis (HRA) in probabilistic safety assessment (PSA) for Korea standard nuclear power plants, Ulchin Unit 3&4, to improve it performed at under design. The HRA for Ulchin Unit 3&4 is assessed as higher than Grade I based on ASME PRA standard and as higher than Grade 2 based on NEI PRA peer review guidance. The major items to be improved identified through the evaluation process are the documentation, the systematic human reliability analysis, the participitation of operators in the works and review of HRA. We suggest the guidance on the identification and qualitative screening analysis for pre-accident human errors and solve some items to be improved using the suggested guidance.
