A 66-year-old patient undergoing regular follow-up at Samsung Medical Center after left lower lobectomy visited the emergency department around 9 months postoperatively because of nausea and vomiting after routine esophagogastroduodenoscopy at a local clinic. Abdominal computed tomography showed the stomach herniating into the left thoracic cavity. We explored the pleural cavity via video-assisted thoracic surgery (VATS). Adhesiolysis around the herniated stomach and laparotomic reduction under video assistance were successfully performed. The diaphragmatic defect was repaired via VATS. The postoperative course was uneventful, and he was discharged with resolved digestive tract symptoms.

Background: Patients with chronic ITP (idiopathic thrombocytopenia) frequently do not require comprehensive medication for daily life. Usually, it had been regarded that postoperative bleeding after a simple or surgical extraction is easily controlled by simple local measures even in patients with ITP. This lack of regular medication usage can sometimes lead practitioners or patients to underestimate the potential life-threatening risk of ITP. There had been no report on postoperative hemorrhage in a patient with ITP related to dental implant surgery. Case presentation: This report presented a life-threatening postoperative hemorrhage after dental implant surgery in an adult with chronic ITP and subsequent emergency management after severe bleeding and airway compromise. Conclusion: The presented case emphasizes the thorough hematological evaluation of the patients even for patients who do not take any specific medications for asymptomatic, chronic ITP.

The current status of local road pavement management in Jeollabuk-do only relies on the accomplishments of the site construction company's pavement repair and is only managed through Microsoft Excel and word documents. Furthermore, the budget is irregular each year. Accordingly, a systematic maintenance plan for local roads is necessary. In this paper, data related to road damage and road environment were collected and processed to derive possible areas which could suffer from road damage. The effectiveness of the methodology was reviewed through the on-site inspection of the area. According to the Ministry of Land, Infrastructure and Transport, in 2018, the number of damages on general national roads were about 47,000. In 2019, it reached around 38,000. Furthermore, the number of lawsuits regarding the road damages were about 93 in 2018 and it increased to 119 in 2019. In the case of national roads, the number of damages decreased compared to 2018 due to pavement repairs. To measure the priorities in maintenance of local roads at Jeollabuk-do, data on maintenance history, local port hole occurrence site, overlapping business section, and emergency maintenance section were transformed into data. Eventually, it led to improvements in maintenance of local roads. Furthermore, spatial data were constructed using various current status data related to roads, and finally the data was processed into a new form that could be utilized in machine learning and predictions. Using the spatial data, areas requiring maintenance on pavement were predicted and the results were used to establish new budgets and policies on road management.

Objective : Trigeminal neuralgia (TN) is a severe neuropathic condition that affects several elderly patients. It is characterized by uncontrolled pain that significantly impacts the quality of life of patients. Therefore, the condition should be treated as an emergency. In the majority of patients, pain can be controlled with medication; however, other treatment modalities are being explored in those who become refractory to drug treatment. The use of the trigeminal nerve block with a local anesthetic serves as an excellent adjunct to drug treatment. This technique rapidly relieves the patient of pain while medications are being titrated to effective levels. We report the efficacy and safety of percutaneous trigeminal nerve block in elderly patients with TN at our outpatient clinic. Methods : Twenty-one patients older than 65 years with TN received percutaneous nerve block at our outpatient clinic. We used bupivacaine (1 mL/injection site) to block the supraorbital, infraorbital, superior alveolar, mental, and inferior alveolar nerves according to pain sites of patients. Results : All patients reported relief from pain, which decreased by approximately 78% after 2 weeks of nerve block. The effect lasted for more than 4 weeks in 12 patients and for 6 weeks in two patients. There were no complications. Conclusion : Percutaneous nerve block procedure performed at our outpatient clinic provided immediate relief from pain to elderly patients with TN. The procedure is simple, has no serious side effects, and is easy to apply.

Objectives: The purpose of this study is to investigate the knowledge, confidence and coping ability about emergency treatment, and the impact of right knowledge and confidence in practice on coping ability in part of dental hygienists. In addition, we suggest emergency treatment knowledge for develop substantive education program applicable to clinical as required data. Methods: This subjects were 259 dental hygienists working in dental setting Seoul, Gyeonggi-do from June 5 to July 20, 2016. We analyzed the data with frequency analysis, descriptive statistics, t-test, one-way ANOVA, pearson correlation coefficient, regression analysis by using SPSS. Results: Emergencies experienced by a dental hygienist in dental practice were fainting, local anesthetic allergies, and seizures. As a result of comparing the first aid knowledge, self-confidence, coping ability according to general characteristics of the study subjects, university graduation was higher than college and 3~5 years of working experience showed higher self confidence(F=3.837, p=0.023). The performance of self confidence and coping ability according to the characteristics of first aid showed high results in first aid training and dental hygienist having CPR license. Based on multiple regression analysis, confidence about emergency treatment is the biggest impact on coping ability(p<0.05). Conclusions: Dental hygienists need to develop and provide programs that can improve the ability of dental hygienists to respond appropriately and promptly in case of emergencies by recognizing the importance of first aid through conservative education.

Injury of permanent teeth by trauma usually occurs to $8{\sim}10\;years$ old children, in mixed dentition. Fracture, dislocation, intrusion, extrusion, avulsion are the common types of trauma in teeth. The injuries which teeth are dislocated from the alveolar sockets can be treated by reduction and fixation. In this case report two children visited Wonkwang University Dental Hospital after the emergency treatment of tooth injury by other medical institutes. In these cases the injured teeth were not reducted properly and showed premature contact. So the teeth were dislocated from the alveolar sockets intentionally and fixed again in the proper position. Unproper reduction can cause premature contact, delay of healing, difficulty of mastication, and malocclusion. For this reason emergency rooms or local dental clinics where patients with dental trauma can be examined first, must know well about the treatment procedure of the injured teeth and should be consulted to the profession when necessary.

Large scale earthquake was occurred in different parts of the world like Japan (in 1995), Republic of Pakistan (2005), in China (2008) etc and enormous structures were damaged. As a result of collapse of school buildings structures numerous students are died and it had a big impact on the international community. Therefore, the interest of preparing the seismic resistant school building structures in our country is increases as school building are used as emergency shelter for local residents. But the current standard of seismic design ratio of 3.7% is applied for school building in Korea which is only significant earthquake damage is expected. In order to overcome the current situation, seismic performance evaluation is carried out for the existing school building and an accurate and appropriate seismic retrofit is required based on performance evaluation to upgrade the existing school buildings. In this paper, nonlinear analysis on existing school buildings for ATC-40(Applied Technology Council, ATC) and FEMA-356(Federal Emergency Management Agency, FEMA) are carried out using the capacity spectrum method to evaluate seismic performance and to determine the need for retrofitting. In addition, after reinforcement to enhance the seismic performance is applied the seismic performance evaluation is carried out to verify the effectiveness of seismic retrofit.

The aim of this study is to identify future-oriented tasks for Korean dental hygienists based on a literature review. A literature search is performed using 14 keywords related to tasks carried out by dental hygienists, and included articles published from 2000 to 2019 in the databases KISS, RISS, DBpia, NDSL, Papersearch, Pubmed, and Google Scholar. Six reviewers assessed the titles and abstracts of articles, and an article was selected if the study was considered to cover future-oriented tasks for Korean dental hygienists. Based on the results six local studies and two foreign studies were used for literature review and data extraction. In total, 38 tasks were classified as future-oriented tasks of dental hygienists according to the following criteria: 1) tasks that were specifically referred to as future-oriented tasks, and 2) tasks that could be classified as future-oriented tasks although no specific reference was made. Of these, the most frequently mentioned tasks were measuring periodontal pocket depth, dental hygiene assessment, providing dietary advice, infiltration anesthesia, and root planing. These were extracted from five of the eight studies, including both local and foreign studies. Dental hygiene planning, emergency, emergency management, and smoking cessation were the next most common tasks based on four studies. Even though some of these future-oriented tasks for Korean dental hygienists are included in the dentistry curriculum, and are currently performed as clinical practice for dental hygienists. Nonetheless, the reference to the legal scope is unclear. It is necessary to reconsider the scope of tasks of dental hygienists to reflect changes in domestic and foreign dental care delivery, thereby contributing to the oral health promotion of the public, where safety is guaranteed under legal protection.

Objective : Since the outbreak of the coronavirus disease 2019 (COVID-19) pandemic, neurointerventionists have been increasingly concerned regarding the prevention of infection and time delay in performing emergency thrombectomy procedures in patients with acute stroke. This study aimed to analyze the effects of changes in mechanical thrombectomy protocol before and after the COVID-19 pandemic on procedure time and patient outcomes and to identify factors that significantly impact procedure time. Methods : The last-normal-to-door, first-abnormal-to-door, door-to-imaging, door-to-puncture, and puncture-to-recanalization times of 88 patients (45 treated with conventional pre-COVID-19 protocol and 43 with COVID-19 protection protocol) were retrospectively analyzed. The recanalization time, success rate of mechanical thrombectomy, and modified Rankin score of patients at discharge were assessed. A multivariate analysis was conducted to identify variables that significantly influenced the time delay in the door-to-puncture time and total procedure time. Results : The door-to-imaging time significantly increased under the COVID-19 protection protocol (p=0.0257) compared to that with the conventional pre-COVID-19 protocol. This increase was even more pronounced in patients who were suspected to be COVID-19-positive than in those who were negative. The door-to-puncture time showed no statistical difference between the conventional and COVID-19 protocol groups (p=0.5042). However, in the multivariate analysis, the last-normal-to-door time and door-to-imaging time were shown to affect the door-to-puncture time (p=0.0068 and 0.0097). The total procedure time was affected by the occlusion site, last-normal-to-door time, door-to-imaging time, and type of anesthesia (p=0.0001, 0.0231, 0.0103, and 0.0207, respectively). Conclusion : The COVID-19 protection protocol significantly impacted the door-to-imaging time. Shortening the door-to-imaging time and performing the procedure under local anesthesia, if possible, may be required to reduce the door-to-puncture and door-to-recanalization times. The effect of various aspects of the protection protocol on emergency thrombectomy should be further studied.

Medical schools realize their social accountability in cultivating future doctors as decision-makers of medical care in the future society as an axis of society and carrying out communication, research, and medical service (medical care). This study summarized the social accountability status of eight medical schools in Korea, including the characteristics, activities, and programs in the sociocultural context. The data from the self-evaluation research reports of eight medical schools were classified and organized according to education, research, and medical care services. The medical schools offer related subjects, community service activities, and clinical practice, allowing active participation in local health promotion and disease prevention. Community health information research was conducted considering the difference between the local natural environment in which the medical school is located and the frequency of diseases. Medical schools and hospitals collaborated to conduct domestic and foreign health education volunteer activities. Social accountability must be prioritized, considering the importance of medical schools' functions and roles in a high knowledge-information society. Both doctors' medical capacity and competence to actively participate in developing medical care and health policies for the community should be strengthened.
