Herein, we describe the case of a 20-year-old woman who presented with dysphagia of 2 months' duration associated with vomiting, moderate abdominal pain, decreased oral intake, and significant weight loss. During the past 3 years, the patient experienced intermittent mild abdominal pain with infrequent vomiting. Endoscopy at Jordan University Hospital showed a mass in the esophagus, and endoscopic biopsies were performed. The preliminary histopathological report excluded malignancy. Two days after endoscopy, the patient presented to the emergency department complaining of severely worsening pain and total dysphagia. The pain persisted despite intravenous paracetamol administration, which was concerning for esophageal perforation; therefore, an urgent surgical intervention was performed. The mass was removed surgically, along with a para-esophageal lymph node. The final histopathological results of the endoscopic and resected specimens supported the diagnosis of pseudomyogenic hemangioendothelioma (PMHE). This is the first case reporting esophageal involvement of PMHE.

Horizontal root fracture (HRF) is a result of trauma to teeth and periodontium, which implies severe injury to cementum, dentin, and pulp. This is a rare case of HRF in the maxillary lateral incisor of a 62-year-old male who only presented persistent gingival swelling, fistula, and dull pain at first. An apical radiolucency of unknown origin turned out to be a result of hidden HRF at the coronal third level that was later visualized radiographically during endodontic treatment. The tooth was scheduled to be extracted upon the patient's agreement. The purpose of this report is to alert clinicians about the importance of diagnosing HRF through thorough clinical and radiographic examinations. Where there is persistent fistula without proper cause, HRF should be considered as a causative factor, and the diagnosis could be effective with aid of cone beam computed tomography, electronic root apex locator, as well as other clinical signs.

We describe a case of gastrocnemius muscle rupture in a goral that got caught in a live trap set up to capture wild boars. We established a diagnostic method based on clinical signs and imaging examination findings, including magnetic resonance imaging for gastrocnemius muscle rupture with symptoms such as hindlimb lameness and plantigrade posture of unknown cause in wild animals. Although this condition is rare, this report will help veterinarians diagnose several diseases of the musculoskeletal and nervous systems in wild animals. This is the first report of successful diagnosis and treatment of gastrocnemius muscle rupture in gorals in Korea.

Objectives: The purpose of this study is to report a case of lymphadenopathy and hearing loss in a patient after coronavirus disease 2019(COVID-19) vaccination. Methods: The patient diagnosed as lymphadenopathy and hearing loss(sensorineural hearing loss) after the first and second rounds of the Pfizer COVID-19 vaccination. We applied Korean medical treatment including herbal medicine and acupuncture for lymphadenopathy and SSNHL. We used VAS(Visual Analog Scale), CT-scan and Pure Tone Audiometry to estimate they symptoms. Results: After the treatment, general symptoms of lymphadenopathy and hearing loss including aural fullness showed big improvement. Conclusions: This case report shows effect of Korean medicine on lymphadenopathy and SSNHL and suggests a possibility of Korean medicine to treat adverse events following COVID-19 vaccination.

Very few studies have been reported on upper extremity replantation following traumatic amputation. This case study aimed to report the progress of a patient treated with complex Korean medicine for 1 year after elbow replantation. The patient mainly complained of forearm sensory loss, muscle weakness, and hand pain after undergoing upper limb amputation and emergency replantation. He was hospitalized for approximately 50 days and then received outpatient treatment for approximately 10 months, followed by electroacupuncture, moxibustion, Chuna, herbal medicine, and transcutaneous electrical nerve stimulation. The muscle strength of the wrist joint improved to good (flexion) and fair (extension), and the forearm sensation was partially recovered approximately 10 months after the onset. To our knowledge, this is the first case report on replantation rehabilitation in Korean medicine, and it suggests that complex Korean medicine treatment might be beneficial for patients undergoing replantation after upper extremity amputation.

Foraminifera are unicellular eukaryotes widely distributed in marine and transitional marine environments. They play important roles in marine food webs and geochemical cycles and have physiological properties like the formation of calcareous tests and nitrogen respiration. Research on species diversity, distribution and endemism are essential in biogeography and biodiversity conservation. Here, we report three unrecorded species of foraminifera (Hemirotalia foraminulosa, Planispirillina denticulogranulata and Oolina brevisolenia) collected from Jeju Island and the South Sea (Korea). Planispirillina denticulogranulata is the second Planispirillina species recorded in Korea, which can be distinguished from congeners by its tubercles on the ventral side and grooves on the spiral suture. Hemirotalia foraminulosa is differentiated from the only congener H. calvifacta by multiple-scattered pits on the umbilicus, and it is the first report of Hemirotalia from Korean water. Oolina brevisolenia has specific bifurcating costae that characterize it from other congeners. This study contributes to documentation of the foraminiferal biodiversity in Korea, moreover, provides an essential basis for the expanded studies on modern foraminifera.

The purpose of this case report is to introduce a case of immediate results with TMJ balancing therapy (TBT) in the treatment of chronic patellofemoral pain (PFP). A 17-year-old female patient with 4-month-old chronic knee pain that was unresponsive to conventional treatment was treated with TBT for a total of 5 sessions. The primary outcomes were evaluated using the Numeric Rating Scale (NRS) and the Korean version of the Western Ontario and McMaster Universities Osteoarthritis Index (KWOMAC). Following the first treatment, the NRS decreased rapidly, and the KWOMAC improved after a total of five treatments. These findings suggest that TBT can be an effective pain management option for chronic PFP patients with temporomandibular joint malposition. However, as this study is a report of a single case, further research is necessary.

Superficial radial neuropathy is a purely sensory neuropathy, usually caused by nerve entrapment in the distal forearm. We report a case of superficial radial neuropathy caused by the anomalous course of the superficial radial nerve, which was found to be spirally encircling the brachioradialis tendon in the distal forearm. To the best of our knowledge, this is the first report of an anatomical variant of the superficial radial nerve that causes neuropathy.

Purpose : The act of reporting child abuse by people obliged to report child abuse is a way to detect long-term incidents of child abuse in early stages and to prevent a vicious cycle of social crimes. Thus, this study intends to enhance the reporting of child abuse through a study on the perception of people obliged to report child abuse through the public service announcement on child abuse. Methods : First, in order to identify the demographic characteristics of the subjects, the frequency and percentage were calculated. Second, in order to verify the reliability of the variables, Cronbach ${\alpha}$ was calculated. Third, in order to examine the perception of people obliged to report child abuse and the perception of reporting, a t-test (verification) and One-way ANOVA were conducted. Fourth, in order to identify the relationship between variables, a Correlation analysis was conducted. Result : The results show that people obliged to report child abuse did not perceive the public service announcement on child abuse positively and it varied depending on their jobs. The correlation between the public service announcement on child abuse and sub-factor of perceptions of reporting showed that a positive correlation was found in reliability, interest, understanding, perceiving the public service announcement on child abuse, perceiving severity and effectiveness, whereas a negative correlation was found in perceiving hazards. Conclusion : The education for preventing child abuse is required by the job type of people obliged to report. It is necessary to convey the message of effective public service announcement. The public service announcements on child abuse must be nationwide and long-term projects.

The purpose of this study is to explore application of topic modeling for topic analysis of book report. Topic modeling can be understood as one method of topic analysis. This analysis was conducted with texts in 23 book reports using LDA function of the "topicmodels" package provided by R. According to the result of topic modeling, 16 topics were extracted. The topic network was constructed by the relation between the topics and keywords, and the book report network was constructed by the relation between book report cases and topics. Next, Centrality analysis was conducted targeting the topic network and book report network. The result of this study is following these. First, 16 topics are shown as network which has one component. In other words, 16 topics are interrelated. Second, book report was divided into 2 groups, book reports with high centrality and book reports with low centrality. The former group has similarities with others, the latter group has differences with others in aspect of the topics of book reports. The result of topic modeling is useful to identify book reports' topics combining with network analysis.
