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.

Proximal flow control achieved with a balloon guide catheter (BGC) during endovascular treatment of acute ischemic stroke is reviewed in this article. In clinical practice, BGCs offer a multi-faceted approach for clot retrieval by creating proximal flow arrest, reducing embolic burden, and shortening procedure time. Evaluation of frontline thrombectomy procedures with BGCs revealed advantages of combined use over the conventional guide catheter (CGC), notably in the significant reduction of distal emboli to both the affected and previously unaffected territories. Recently, new measures of early and complete reperfusion at first thrombectomy pass have been identified as independent predictors of improved outcomes, which were consistently demonstrated with use of BGC as a safe and effective option to minimize number of passes during intervention. Prior randomized controlled trials reported the positive correlation between BGC-treated patients and a lower risk of mortality as well as shortened procedure time. While BGC use is more common in stent retriever-mediated mechanical thrombectomy, preliminary data has shown the potential benefit of device application during contact aspiration thrombectomy to achieve successful recanalization. However, the question of which major endovascular strategy reigns superior as a frontline remains to be answered. Along with clinical case assessments, BGC performance during in-vitro simulation was analyzed to further understand mechanisms for optimization of thrombectomy technique.

Objectives : This paper studies how the people of the past deal with constipation before the introduction of modern medical knowledge. Then, the paper selected some of the methods that use food ingredients with little to no side effects, and studied them to find a basic set of data that can be applied to today's medical practices. Methods : This paper reviewed six literatures: China's Eumsunjungyo, Nonohangeon, and Shiggamboncho, and Chosun's Singnyochanyo, Donguibogam, and Jejungsinpyeon. The food cures related to constipation were studied to discover what ingredients and preparation forms were used, how they were taken, what types of prescriptions existed, and how they were applied. Results : The food cure for constipation included ingredients such as mazi, suzi, sesame, honey, yiyiren, yuliren, xingren, taoren, and rice. These ingredients are known for replenishing the body's fluid and humor and allowing the better flow of qi. Mazi porridge, suma porridge, raw sesame oil, suzhu porridge, and suxing porridge were effective in dealing with the conspitation caused by heat, and jingshen wan, yiyiren porridge, yuliren porridge, yulirenyiyiren porridge, xingren porridge, and taoren porridge were effective in taking care of conspitation caused by qi deficiency. Conclusions : With a constipation caused by heat, it is good to take mazi and spinach regularly which is helpful in cooling down the heat. For senior citizens, constipations occur due to the qi deficiency that leads to the lack of fluid and humor. In this case, suzhu porridge should be taken regularly together with milk and sesame oil in order to replenish the qi. This will tonify the amount of qi and moisten the large intestines, which will be also helpful in tonifying the body itself.
