Oral submucous Fibrosis(OSF) is an insidious chronic disease affecting the mucosa of the oral cavity and occasionally extending into the pharynx and esophagus. It is associated with a genetic predisposition and alterations, infectious and viral agents, carcinogens, nutritional and immunological factors. the etiology is obscure but it is correlated with a hypersensitivity to capsaicin, secondary to chronic iron and/ or vitamin B complex deficiencies or exposure to cashew kernel oil. We report a patient who had a month opening limitation caused by a fall when he was 8 years old despite several treatments at other hospitals. Excellent results were obstained by releasing the scar tissue using a standard split-thickness skin graft(STSG) which obtained from the thigh. It is important to recognize as a precancerous condition and to inspect the excision site and the remaining oral mucosa during long-term follow-up on a regular basis.

Objective: Epinephrine is a first-line drug for anaphylaxis, but a poor prognosis can occur if not administered properly. This study compared the clinical features of patients with anaphylaxis in the emergency department (ED) according to epinephrine administration. Methods: This was a retrospective cross-sectional study using ED-based data retrieved from a tertiary university hospital. Patients diagnosed with anaphylaxis between 2018 and 2020 were enrolled in this study. The patients with anaphylaxis were classified according to epinephrine administration, and the clinical features were compared. The adjusted odds ratios (AORs) with a 95% confidence interval (CI) were calculated for the main factors associated with epinephrine use. Results: Among 205 eligible patients with anaphylaxis, 157 (76.6%) were treated with epinephrine. The main contributing factors influencing epinephrine use were patients with cardiovascular symptoms (AOR=2.97; 95% CI, 1.26-7.01) and patients transferred from other hospitals (AOR=0.37; 95% CI, 0.16-0.85). Conclusion: The major factors influencing epinephrine use in the ED when patients with anaphylaxis presented with cardiovascular symptoms were identified. It is essential to prevent potentially fatal consequences in patients with anaphylaxis through appropriate epinephrine administration.

Formaldehyde in adhesives is used as preseratives as well as adhesives themeseles such as phenol-formaldehyde, carbamide-formaldehyde and melarnine-forma 1dehyde. Formaldehyde content in 43 kinds of adhesives used at present in Korea was determined by lutidine method. The study result was as follows. 1. The The distribution of formaldehyde concentrations of 43 different kinds of adhesives was in the 0 to 333. 9 ppm ranges. 2. High concentration of formaldehyde was observed in 3 kinds of wall paper adhesives and 1 kind of stationary adhesive, which has an important clinical significance because of their frequent contact sources of domestic uses.

The purpose of this study is to derive cost-benefit analysis methods and procedures applicable to effluent limitation standards of hazardous and noxious substances in marine industrial facilities. The scope of the study was limited to marine industrial facilities in Incheon. The scope of the study was limited to the eco-nomic analysis of marine industrial facilities in Incheon. The analysis results are as follows. First, in terms of cost, the cost of introducing technology due to the application of BAT was about 3.8 billion won for 100 tons, 37.7 billion won for 1,000 tons, and 188.6 billion won for 5,000 tons, totaling 230 billion won. Next, the loss cost was calculated as about 611.2 bil-lion won in operating loss, 63.5 billion won in bankruptcy loss, 19.9 billion won in employment loss, and 63.5 billion won in local economic loss. Second, the benefits were about 52.3 billion won in fishing production protection profits, About 1.2547 trillion won in local tourism protection profits, and about 55.3 billion won in civil health protection profits, a total of 1.3724 trillion won. Accordingly, the B/C ratio was calculated to be 1.39, and accordingly, the introduction of new technologies according to the application of BAT was found to be economical.
