  • Almost every country around the world has been focusing on food safety in intense and multifaceted ways. The use of Hazard Analysis Critical Control Points (HACCP) is widely accepted as a food safety management system. This paper investigates the success factors of HACCP practices with reference to the domains of food production, processing and delivery. A literature review of food safety and management articles was conducted. Using the keywords search, the online Emerald Database was used and a total of 102 journal articles were identified between 1994 and 2007. The study examined a list of 20 success factors. Results show that 'food regulations,' 'role of the industry,' 'government policies and interventions,' 'training on food safety and hygiene,' and 'food contamination and/or poisoning' share the spotlight as being the most critical factors for HACCP practices in organisations. Future research could investigate a holistic paradigm that incorporates the success factors and aligns HACCP measures for attaining safety performance goals.

  • As computers can express and utilize information in a semantic dimension different from the real world, humans have opened the door to the digital world and have played a pivotal role in the transformation of the human habitual environment. Using metaverse, it can be possible to predict concepts such as virtual currency, artificial intelligence, and virtual reality, which have now become possible for practical systemic visualization. In order to implement the metaverse in the realm of technology, it requires not only a multifaceted discussion on the platform, but also research on an architect that can include the intrinsic complexity of the metaverse. In this paper, we discuss the architecture for an open metaverse platform based on convergence wrapping that can converge various contents into one space, and propose a comprehensive platform design.

  • This study analyzes the combat case involving military drones during the Azerbaijan-Armenian War, which erupted on September 27, 2020. The background of the war revealed that Azerbaijan extensively and aggressively employed offensive drones, which played a decisive role in reshaping the dynamics of the battlefield. Despite Azerbaijan's GDP of $4.639, which corresponds to the level of a developing country, and its 64th rank in global military strength, the country boldly allocated a significant portion of its budget to develop its drone capabilities in preparation for the war. As a result, Azerbaijan effectively utilized offensive drones acquired from Turkey and Israel to neutralize hundreds of tanks, armored vehicles, artillery units, and air defense systems. The purpose of this study is to examine this context and explore how our Korean military organization can enhance its combat capabilities by developing a drone combat system, thereby enabling an effective response posture against multifaceted threats.

  • Shoulder impingement syndrome (SIS) is a common musculoskeletal condition characterized by pain and functional limitation due to the impingement of subacromial structures. This comprehensive review elucidates the complex nature of SIS, covering its pathophysiology, diagnostic methodologies, treatment options, and preventive measures. Through an exhaustive examination of current literature and clinical practices, the review highlights the importance of a multifaceted approach to SIS management. Physical therapy plays a pivotal role, focusing on exercises to strengthen shoulder musculature, enhance scapular stability, and improve range of motion. The review also discusses the strategic use of medications such as NSAIDs and corticosteroid injections, emphasizing their effectiveness in pain and inflammation management. Additionally, it advocates for structured rehabilitation programs post-treatment to restore function and prevent recurrence, recommending preventive strategies like ergonomic adjustments, targeted exercises, and proper technique training. This paper underscores the need for personalized and evidence-based treatment strategies, integrating physical therapy and pharmacological management when necessary.

  • Aging is accompanied by a time-dependent progressive deterioration of multiple factors of the cellular system. The past several decades have witnessed major leaps in our understanding of the biological mechanisms of aging using dietary, genetic, pharmacological, and physical interventions. Metabolic processes, including nutrient sensing pathways and mitochondrial function, have emerged as prominent regulators of aging. Mitochondria have been considered to play a key role largely due to their production of reactive oxygen species (ROS), resulting in DNA damage that accumulates over time and ultimately causes cellular failure. This theory, known as the mitochondrial free radical theory of aging (MFRTA), was favored by the aging field, but increasing inconsistent evidence has led to criticism and rejection of this idea. However, MFRTA should not be hastily rejected in its entirety because we now understand that ROS is not simply an undesired toxic metabolic byproduct, but also an important signaling molecule that is vital to cellular fitness. Notably, mitochondrial function, a term traditionally referred to bioenergetics and apoptosis, has since expanded considerably. It encompasses numerous other key biological processes, including the following: (i) complex metabolic processes, (ii) intracellular and endocrine signaling/communication, and (iii) immunity/inflammation. Here, we will discuss shortcomings of previous concepts regarding mitochondria in aging and their emerging roles based on recent advances. We will also discuss how the mitochondrial genome integrates with major theories on the evolution of aging.

  • Objectives: This descriptive survey study aimed to identify factors that affect job satisfaction among nurses working in integrated nursing care service wards and to explore measures to increase job satisfaction among these nurses. Methods: Data were collected between July 20 and August 3, 2018 from nurses working in integrated nursing care service wards in Busan and Changwon city, in Korea. Data were analyzed with SPSS/WIN 23.0 software(IBM corp., Armonk, NY, USA). Results: Factors affecting job satisfaction among nurses working in integrated nursing care service wards were identified as follows: professional self-concept (${\beta}=.32$, p=.003), which is a subdomain of nursing professionalism, and nursing foundations for quality care (${\beta}=.30$, p=.001), which is a subdomain of nursing work environment. The model had an explanatory power of 54.7%. Conclusions: Nursing professionalism should be strongly established among nurses, as nurses are key players in a health system that allows stable and expanded operations of integrated nursing care. Intervention measures that create a better work environment for nurses should also be implemented. Furthermore, it is necessary to develop systematic strategies and multifaceted efforts to increase nurses' job satisfaction in integrated nursing care service wards.

  • Acute myocardial infarction (AMI) is a multifaceted syndrome influenced by the functions of various extrinsic and intrinsic pathways and pathological processes, which can be detected in circulation using biomarkers. In this study, we investigated the secretome protein profile of induced-hypertrophy cardiomyocytes to identify next-generation biomarkers for AMI diagnosis and management. Hypertrophy was successfully induced in immortalized human cardiomyocytes (T0445) by 200 nM ET-1 and 1 μM Ang II. The protein profiles of hypertrophied cardiomyocyte secretomes were analyzed by nano-liquid chromatography with tandem mass spectrometry and differentially expressed proteins that have been identified by Ingenuity Pathway Analysis. The levels of 32 proteins increased significantly (>1.4 fold), whereas 17 proteins (<0.5 fold) showed a rapid decrease in expression. Proteomic analysis showed significant upregulation of six 14-3-3 protein isoforms in hypertrophied cardiomyocytes compared to those in control cells. Multi-reaction monitoring results of human plasma samples showed that 14-3-3 protein-zeta levels were significantly elevated in patients with AMI compared to those of healthy controls. These findings elucidated the role of 14-3-3 protein-zeta in cardiac hypertrophy and cardiovascular disorders and demonstrated its potential as a novel biomarker and therapeutic strategy.
