Ankylosis of the temporomandibular joint (TMJ) is a condition in which the mandibular condyle fuses with the mandibular fossa through fibrous or bone tissue. It is a debilitating pathology that interferes with chewing, speaking, and oral hygiene. Currently, alloplastic reconstruction is considered the gold standard for treating severely compromised TMJs, such as in ankylosis. The article describes a patient with a history of facial trauma, with bilateral ankylosis of the TMJs, inability to open his mouth, and poor dental condition. Due to a long period of immobilization of approximately 40 years, the initial treatment plan was to remove the ankylosis bilaterally and install customized PMMA (polymethylmethacrylate) spacers. The patient gained mouth opening and improved chewing quality with one year of customized spacer use prior to definitive alloplastic replacement with stock-type TMJ prostheses. Customized joint spacers are a provisional treatment option when definitive alloplastic reconstruction is not indicated. Spacers provide the patient with progressive jaw function and mobility gains.

The Internet of Things (IoT) is being used in a wide variety of fields due to the recent 4th industrial revolution. In particular, research is being conducted that combines IoT with the medical field such as telemedicine. Among them, the field of shock detection is a big issue in the medical field because the causes of shock are diverse, treatments are very complex, and require a high level of medical knowledge and experience. The transmission of infectious diseases is common when treating critically ill patients, especially patients with shock. Thus, to effectively care for shock patients, we propose an architecture that continuously monitors the patient's condition, and automatically recommends a drug injection treatment according to the patient's shock condition. The patient's hemodynamic information is continuously monitored, and the patient's shock generation information is recorded periodically. With the recorded patient information, the patient's condition is determined and automatically injected with necessary medication. The medical team can find out whether the patient's condition has improved by checking the recorded information through web applications. The study can help relieve the shortage of medical personnel and help prevent transmission of infectious disease in medical staff. We look forward to playing a role in helping medical staff by making recommendations for the diagnosis and treatment of complex and difficult shocks.

The inner ear constitutes a complex organ responsible for auditory perception and equilibrium. It comprises diverse cellular entities operating collaboratively to perceive and transmit sensory information to the brain. Inner ear disease is a sophisticated and multifactorial scenario substantially impacting the quality of life of affected individuals. Gaining insights into the developmental process of the inner ear is crucial for diagnosing and treating inner ear diseases, which can lead to hearing loss and impaired balance. Recent research in inner ear development and associated pathophysiology has focused on several pivotal domains, including identifying new genes and signaling pathways involved in inner ear development, using stem cells for inner ear regeneration, and developing novel therapies for inner ear diseases. Recent advances in genetics research have shed new light on the fundamental etiologies of inner ear diseases, with a growing body of evidence suggesting that genetic mutations might exert a pivotal influence on the development and progression of this condition. In this review, we have delved into certain common genetic mutations linked to inner ear disorders. We also discussed ongoing research endeavors and future directions for understanding the genetic mechanisms underlying this condition and potential therapeutic avenues.

The effect of pathogenicity on trehalose accumulation was studied using six species of entomopathogenic nematodes adapted to either cold or warm temperature conditions. Also, trehalose accumulation was studied by treating nematodes with glycerol or oil at trehalose concentration and mortality of cold temperature $condition(5^{\circ}C)$, S. longicaudum Gl was increased 50% than control. And at trehalose concent and mortality of warm temperature $condition(30^{\circ}C)$, S. glaseri Agr B3 was increased 45%. Intracellular trehalose accumulation was increased with treatment with 20% glycerol or oil. As the final results, the pathogenic duration of nematodes was increased as intracellular trehalose accumulation was increased

Cotton fabrics were treated with some commercial non-formaldehyde and low-formaldehyde resins, and then their effect on the physicochemical properties were respectively investigated including formaldehyde release, tear strength, shrinkage, and wrinkle recovery. Formaldehyde release less than 10ppm was obtained only by non-formaldehyde resin. Considering other factors, the optimal concentration of non-formaldehyde resin was shown to be 9-11%. In case of low-formaldehyde type, 5-7% resin concentration and curing temperature of $160{\sim}170^{\circ}C$ were recommended for optimal finishing condition. The choice and combination of resins and catalysts were also important factors, and preliminary considerations before treating cotton fabrics with resins used in this study are also important to get much better results.

We investigated 8th grade science textbooks and their instructor's manuals treating the ideal condition for isochronism of a simple pendulum. The isochronism, i.e. the period is independent of amplitude, is satisfied only if the amplitude is very small. This is so called "ideal condition" for isochronism of a simple pendulum. Most textbooks and instructor's manuals are found not to state this ideal condition properly, which often leads to the deviation between experimental data and theoretical calculation. This difference between theoretical and experimental results makes students to create a sense of alienation from the real world and eventually keeps them away from physics. We thus study the cycloidal pendulum as an alternative method to test the isochronism regardless of amplitude and discuss the practical utility of it in class.

Any compound which disrupts the integrity of psychological aspects of performance, in particular, cognitive ability and psychomotor function analogous to the psychological behaviors of routine life, is known to be behaviorally toxic. A significant level of behavioral toxicity will interfere with patient safety and quality of life, and also may be counter-therapeutic by exacerbating the condition that the drug was prescribed for. Now, behavioral toxicity of psychotropic drugs has become one of the main growth areas of psychopharmacological research. Evaluation of the potential of drug-induced behavioral toxicity is important not only to the experimental researcher involved in human psychopharmacology, but also to the clinical practitioner treating psychiatric patients. This article attempts to describe behavioral toxicity of the three classes of psychotropic drugs - benzodiazepines, antidepressants and neuroleptics. After a brief discussion of some methodological issues arising in the investigation of behavioral toxicity, each of these drug classes is reviewed in the context of practical importance rather than purely scientific concern. The last session summarizes some suggestions for future studies on drug-induced behavioral toxicity.

Abnormal changes in skin color induce significant cosmetic problems and affect quality of life. There are two groups of abnormal change in skin color; hyperpigmentation and hypopigmentation. Hyperpigmentation, darkening skin color by excessive pigmentation, is a major concern for Asian people with yellowe-brown skin. A variety of hypopigmenting agents have been used, but treating the hyperpigmented condition is still challenging and the results are often discouraging. Panax ginseng has been used traditionally in eastern Asia to treat various diseases, due to its immunomodulatory, neuroprotective, antioxidative, and antitumor activities. Recently, several reports have shown that extract, powder, or some constituents of ginseng could inhibit melanogenesis in vivo or in vitro. The underlying mechanisms of antimelanogenic properties in ginseng or its components include the direct inhibition of key enzymes of melanogenesis, inhibition of transcription factors or signaling pathways involved in melanogenesis, decreasing production of inducers of melanogenesis, and enhancing production of antimelanogenic factor. Although there still remain some controversial issues surrounding the antimelanogenic activity of ginseng, especially in its effect on production of proinflammatory cytokines and nitric oxide, these recent findings suggest that ginseng and its constituents might be potential candidates for novel skin whitening agents.

Endometriosis is characterized by the implantation of endometrial cells outside the uterus. This hormone-dependent disease is highly prevalent among women of reproductive age. Clinical symptoms of endometriosis include dysmenorrhea, pelvic pain, and infertility, which can negatively impact the overall quality of life of those affected. The medical treatment of endometriosis serves as an important therapeutic option, aimed at alleviating pain associated with the condition and suppressing the growth of endometriotic lesions. As such, it is employed as an adjuvant therapy following surgery or an empirical treatment after the clinical diagnosis of endometriosis. Dienogest, a fourth-generation progestin, has received approval for the treatment of endometriosis in many countries. A growing body of evidence has demonstrated its efficacy in managing endometriosis-associated pain, preventing symptoms, and reducing lesion recurrence. In this review, we examine the clinical efficacy, safety, and tolerability of dienogest in treating endometriosis. We also provide updated findings, drawing from clinical studies that focus on the long-term use of this medication in patients with endometriosis.
