The development of office-based, unsedated transnasal esophagoscopy (TNE) has proven to be a major technological advance and with time and experience the application of this technology is becoming more widespread. TNE has allowed otolaryngologists to perform a variety of diagnostic and therapeutic procedures in the office setting. Studies consistently demonstrate that the image quality and diagnostic capability of TNE is equivalent to conventional esophagoscopy. The modern TNE endoscopes offer high quality optics, air-insufflation, and irrigation capability through a 2-mm working channel, and the ability to perform biopsies and select procedures. In general, the role of TNE in the head and neck patient is three-fold : to screen for synchronous and metachronous esophageal squamous cell carcinoma (ESCC) ; to differentiate post-treatment changes/symptoms from malignancy ; and to perform certain office-based procedures. TNE offers many specific advantages to the head and neck patient that are not afforded by conventional esophagoscopy. Because of surgical and postirradiation changes, many HNSCC patients have trismus or neck stiffness preventing completion of conventional transoral esophagoscopy. Perhaps most importantly, TNE provides enhanced patient safety, increased tolerability, better practice efficiency, and cost savings. For these reasons, TNE has become a particularly useful tool in the otolaryngologist's armamentarium.

Background: Total hip arthroplasty (THA) is probably one of the most successful surgical interventions performed in medicine. Through the revolution of hip arthroplasty by principles of low friction arthroplasty was introduced by Sir John Charnley in 1960s. Thereafter, new bearing materials, fixation methods, and new designs has been improved. The main concern regarding failure of THA has been the biological response to particulate polyethylene debris generated by conventional metal on polyethylene bearing surfaces leading to osteolysis and aseptic loosening of the prosthesis. To resolve these problems, the materials of the modern THA were developed since then. Methods: A literature search strategy was conducted using various search terms in PUBMED. The highest quality articles that met the inclusion criteria and best answered the topics of focus of this review were selected. Key search terms included 'total hip arthroplasty', 'biomaterials', 'stainless steel', 'cobalt-chromium', 'titanium', 'polyethylene', and 'ceramic'. Results: The initial search retrieved 6921 articles. Thirty-two articles were selected and used in the review. Conclusion: This article introduces biomaterials used in THA and discusses various bearing materials in currentclinical use in THA as well as the newer biomaterials which may even further decrease wear and improve THA survivorship.

Objectives : The objective of this study was to examine the acupoint location of Kyoshin (KI8) from classic literatures. Methods : A review of KI8 location along the meridian route from 18 classics of acupuncture and moxibustion - 『Huangdineijing·Lingshu』, 『Huangdimingtangjingjixiao』, 『Zhenjiujiayijing』, 『Huangdineijingtaisu』, 『Huangdimingtangjiujing』, 『Beijiqianjinyaofang』, 『Waitaimiyaofang』, 『Ishimpo』, 『Taipingshenghuifang』, 『Tongrenshuxuezhenjiutujing』, 『Shengjizonglu』, 『Zhenjiuzishengjing』, 『Shisijingfahui』, 『Shenyingjing』, 『Zhenjiujuying』, 『Yixuerumen』, 『Zhenjiudacheng』, and 『Yizongjinjian』 - was performed. Then, KI7 location on classics and current standard KI8 location were compared. Results : Based on modern standard acupoint location system, the acupoint of KI8 is located on the medial aspect of the leg, in the depression posterior to the medial border of the tibia and it is on the route of spleen meridian. But no classics of acupuncture and moxibustion said KI8 was located on the route of spleen meridian. In addition, KI8 location on classics was largely described as being located in front of KI7, but only in 『Yizongjinjian』 was it written that KI8 was located posterior to KI7. Conclusions : Through a classic literature review, it is possible to explain that KI8 is located posterior to spleen meridian. The acupoint of KI8 seems to be located between medial border of flexor pollicis longus and flexor digitorum longus based on anatomical location.

World practice is evidence of that computer systems of an intellectual support of medical activities bound up with examination of patients, their diagnosis, therapy and so on are the most effective means for attainment of a high level of physician\`s qualification. Such systems must contain large knowledge bases consistent with the modern level of science and practice. To from large knowledge bases for such systems it is necessary to have a medical ontology model reflecting contemporary notions of medicine. This paper presents a description of an observation ontology, knowledge base for the physician of general tipe, architecture, functions and implementation of problem independent shell of the system for intellectual supporting patient examination and mathematical model of the dialog. The system can be used by the following specialist: therapeutist, surgeon, gynecologist, urologist, otolaryngologist, ophthalmologist, endocrinologist, neuropathologist and immunologist. The system supports a high level of examination of patients, delivers doctors from routine work upon filling in case records and also automatically forms a computer archives of case records. The archives can be used for any statistical data processing, for producing accounts and also for debugging of knowledge bases of expert systems. Besides that, the system can be used for rise of medical education level of students, doctors in internship, staff physicians and postgraduate students.

Polymers are the major constructive material of pharmaceutical formulations that play a prime role in designing effective drug-delivery systems and releasing drugs at their sites of application. Polymers are composed of multiple repeating units of high molecular mass components with attendant properties. Most synthetic polymers are non-biocompatible, expensive, and extremely inclined to deliver adverse impacts. Meanwhile, edible polymers obtained from natural sources have gained remarkable recognition for their promising use in modern medicine. Moreover, polymers derived from natural sources are generally preferred due to certain of their unique features such as abundant availability, biocompatibility, nontoxicity, economical, safe, and effective functions that fit the purpose. Polysaccharides including starch, cellulose, hemicellulose, pectin, and mucilage are identified as a major class of naturally obtained molecules that have a substantial role as functional polymers. This review summarizes the potential role of polysaccharides derived from vegetable sources such as adhesives, anticaking agents, binders, disintegrants, emulsifiers, film-framing agents, and thickeners. This is simply an opportunity to abandon synthetic excipients that hurt our bodies and think back to nature from where we originate.

Several chemicals have been developed owing to the progression of industrialization, among which endocrine-disrupting chemicals (EDCs; essential for plastic production) are used as plasticizers and flame retardants. Plastics have become an essential element in modern life because they provide convenience, thus increasing EDCs exposure to humans. EDCs cause adverse effects such as deterioration of reproductive function, cancer, and neurological abnormalities by disrupting the endocrine system and hence are classified as "dangerous substances." Additionally, they are toxic to various organs but continue to be used. Therefore, it is necessary to review the contamination status of EDCs, select potentially hazardous substances for management, and monitor the safety standards. In addition, it is necessary to discover substances that can protect against EDC toxicity and conduct active research on the protective effects of these substances. According to recent research, Korean Red Ginseng (KRG) exhibits protective effects against several toxicities caused by EDCs to humans. In this review, the effects of EDCs on the human body and the role of KRG in protection against EDC toxicity are discussed.

Objective : This study aims to investigate the concept of mental health literacy, its evolution, and its significance in modern healthcare practices. Methods : This paper reviews the evolution of mental health literacy, examining pertinent studies both within the country and internationally. It also addresses the limitations and challenges associated with mental health diagnoses. Results : Findings from various studies indicate that public awareness and recognition of mental health issues are generally inadequate. Identified causes of mental health conditions by study participants point to personal and societal influences, while biological factors are frequently neglected. In South Korea, there is a notable preference for non-professional support over psychiatric interventions. Conclusion : This study highlights the growing importance of mental health literacy in today's society, emphasizing the need for accurate understanding of mental health issues and effective treatment approaches. Similar to physical health literacy, mental health literacy should be considered a basic human right. This perspective marks a shift from a knowledge monopoly held by experts to the inclusion and active involvement of 'people with lived experience' in the mental health service system.

Background: In today's modern world, longer working hours, shift work, and working at night have become major causes of the disruption of our natural circadian rhythms. This study aimed to investigate the effects of the type of shift work (rotating vs. fixed day), duty period (on-duty vs. off-duty), and working period within each shift (nighttime vs. daytime) on the circadian rhythm characteristics of nurses who provide direct patient care. Methods: This cross-sectional study used a purposive sampling method. Cosinor analysis was applied to analyze the actigraphy data of nurses providing direct patient care for seven consecutive days. The linear mixed effects model was then used to determine any variances between shift type, duty period, and working period within each shift for the nurses. Results: The mesor value did not differ according to nurses' shift type, duty period, and working period within each shift. The amplitude was statistically higher in on-duty nurses and in daytime working hours. The acrophase was significantly delayed in nighttime working hours. As well as nurses in rotating shift had experience. Conclusion: Our findings revealed that the peak activity of nurses occurs significantly later at night while working and nurses working during nighttime hours may have a weaker or less distinct circadian rhythm. Thus, this study suggests that limits be placed on the number of rotating nighttime shifts for nurses.

The remarkable economic growth achieved in the modern era has revitalized various industries, including pet trade. More than 2,000 species of non-native species have been introduced to South Korea and approximately 7.7 tonnes of alien turtles are imported annually. Turtles belonging to the family Kinosternidae. They are mostly small and popular pets, although they are designated as Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) species. In the present study, we present the first two species of musk turtles found in the wild in South Korea. On April 5, 2023 and July 8, 2023, an eastern musk turtle (Sternotherus odoratus) and a razorbacked musk turtle (Sternotherus carinatus) were captured in Ilsandong-gu, Goyang-si, Gyeonggi-do and Jung-gu, Daejeon, respectively. The carapace length was 88.6 mm for S. odoratus and 105.68 mm for S. carinatus. They were identified based on their morphological characteristics and mtDNA cytochrome b gene. These turtles were found in waterfront areas with over 1.4 million annual visitors. Both sites were found to have threatened amphibians and reptiles. There is an urgent need to continue monitoring and conducting risk assessments for the protection of endemic species in Korea.
