Research ArticleOpen accessIn the keywordsComparative Analysis of Laboratory Measured and PVTP Software DataOluwasanmi Samuel Teniola, Mercy Isaiah OkegbemiCubic Equations of State (EOS), including the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) models, are foundational in petroleum engineering for modeling the thermodynamic behavior of hydrocarbon systems. These EOS are widely used to predict phase behavior and Pressure-Volume-Temperature (PVT) properties, which are crucial for reservoir simulation, production forecasting, and enhanced oil recovery. However, their predictive accuracy diminishes when applied to complex … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 20 Dec 2025 · 2,761 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEnhanced Antibacterial Activity of Blended Essential Oils against Staphylococcus Aureus and Methicillin-Resistant Staphylococcus AureusMin-Gi Kwon, Ji-Hyuk Kang, Jae Kyung KimWe aimed to evaluate the antibacterial effects of four blended and four single essential oils on the gram-positive bacterium Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA). Minimum inhibitory concentration (MIC) testing was performed using disk diffusion and broth microdilution methods according to the Clinical and Laboratory Standards Institute criteria. The blended essential oils exhibited more powerful antibacterial activity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 16 Apr 2026 · 1,594 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSex-Based and Age-Specific Trends in Gardnerella vaginalis Infection: An Epidemiological Study in Republic of Korea, 2018-2022Hyeok-Jin Kwon, Sun-Gyu Kim, Junmin Lee et al.Sexually Transmitted Infections (STIs) are an important global public health issue caused by various pathogens. STI symptoms can manifest at different times, depending on the sex, age, and infection route. Here, we aimed to assess the occurrence of STIs in the Republic of Korea, explore associated global trends, and identify pathogens with high positivity rates to inform future health policies. … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,928 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComparative Evaluation of Synergistic Antibacterial Effects in Blended Essential Oil against Gram-Positive and Gram-Negative PathogensMin-Gi Kwon, Jae Kyung KimThe rising emergence of multidrug-resistant bacteria has heightened the search for novel antibiotic agents. Essential Oils (EOs) are complex combinations of volatile organic compounds generated by plants, with many exhibiting significant antimicrobial properties. This study evaluates the antibacterial movement of single and blended EOs against representative gram-positive bacteria Staphylococcus aureus and Methicillin-Resistant S. aureus (MRSA) and gram-negative bacteria Escherichia coli … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 7 Jul 2025 · 5,481 accessesView PDF Cite

Research ArticleOpen accessIn the author namesPrevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections in Republic of Korea: Impacts of Sex, Age, and Testing MethodHyeok-Jin Kwon, Sun-Gyu Kim, Junmin Lee et al.The prevalence of Sexually Transmitted Diseases (STDs) is increasing globally, necessitating a quick and accurate diagnosis method for appropriate treatment selection. An analysis of venereal diseases conducted at U2Bio (Jangwon Medical Foundation, Seoul, Republic of Korea) over a 2-year period showed that Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection rates were related to sex, age, and specimen type. We … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 29 Oct 2024 · 5,018 accessesView PDF Cite

Research ArticleOpen accessIn the author namesContent of Phenolic Compounds of Different Organ in Pimpinella brachycarpa Collected from Different Locations in KoreaNam Su Kim, Dae Hui Jung, Kwon Seok Jeon et al.Pimpinella brachycarpa (Kom.) Nakai, reported to have antioxidant activity, is one of the most favored edible greens grown in Asian regions. The present study explores the variation in phenolic compounds in P. brachycarpa collected from different locations in Korea. Six phenolic compounds, i.e., catechin hydrate, chlorogenic acid, ferulic acid, benzoic acid, rutin and quercetin, were detected in the leaves, whereas … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 28 May 2020 · 7,613 accessesView PDF Cite
