Safety and quality assessment systems are very important in manufacture, storage, transportation, and handling of hazardous materials(hazmat) to prevent hazmat disasters. At present, hazardous materials exist everywhere in our daily lives with various forms of plastics, household products of cleaning and washing detergents, fertilizers or petroleum-related products. However, hazardous materials are dangerous substances when they are released to human or environment. Hazardous materials become very widely used substances in the age of oil-based industrial economy. The Korean Ministry of Environment (KMOE) describes about one hundred thousand types of chemicals are produced and used worldwide. Over four hundred new chemicals are introduced in every year. A crucial question for the Korean hazardous material management may have been raised: Will you be safe from hazardous material incidents? The gas leak disaster at Union Carbide's Bhopal, India in 1984 that made over 6,400 people killed and 30,000 to 40,000 people seriously injured is the representative case for the safety of hazmat. Korea becomes vulnerable to hazmat disaster due to the development of high-tech industry. Thus, the risk assessment system is required to Korea for transferring abandoned hazmat management systems to self-correcting safety systems. This research analyzed characteristics of various hazmat incidents applying statistical analysis methods including frequency analysis or analysis of category data to hazmat incidents for ten years. All of three analyses of category data indicate the significance of causality between hazmat incident site groups and seasons, regional groups, and incident casualty groups.

Gastric cancer is the most prevalent cancer in Korea and comprises the second cause of cancer death. Surgery only can provide chance of cure, but most locally advanced cancers recur after a curative resection, even though important advances in the surgical and nonsurgical treatments of gastric cancer have taken place. Preoperative chemotherapy theoretically can provide the advantages of reducing the bulk of tumor, which might improve the R0 resection rate, and of treating micrometastases early. Also, preoperative chemotherapy is expected to render unresectable tumors resectable without increasing postoperative morbidity and mortality. There are many new chemo-therapeutic agents available for the treatment of advanced gastric cancer, but still the most effective agent, the optimal time and number of cycle for administration are still not known. The addition of postoperative chemotherapy through an intraperitoneal route and/or radiotherapy might affect the outcome of surgery favorably, but that hasn't been proved yet. A multicenter prospective randomized phase III trial should be peformed to answer for those questions and to improve the curability of gastric cancer treatment.

The surgical closure of VSD in patient with severe pulmonary hypertension has been considered a difficult problem for surgeons, because sudden hemodynamic change after closure of the defect could bring on high perioperative mortality. Recently, it was reported that UVP(unidirectional valve patch), which allows some blood to flow from right to left in case of acute right heart failure, is effective in improving the postoperative hemodynamics after closing septal defects. This 42-year old woman had suffered from VSD for 20 years and recently complained of worsening exertional dyspnea for three months, and was diagnosed of a large VSD(2.0 cm in diameter) with severe pulmonary hypertension(116/38 mm Hg), equal to systemic arterial pressure. We could successfully close VSD with severe pulmonary hypertension using one UVP and the other UVP for the creative ASD to be prepared against possible acute right heart failure. She was discharged on the fourteenth postoperative day and has been well for twelve months with spontanenous closure of UVP patch at the ninth postopeative month.

CSS for identifying ADEs are sufficiently developed for broad use and they are much more accurate than spontaneous reporting and more time- and cost-effective than manual chart review. Also computer alert systems can be used to identify opportunities to prevent or reduce patient injury associated with a broad range of ADEs. This CSS can be used to identify opportunities to prevent or reduce patient injury associated with preventable ADEs and increase patient safety, increase quality of drug therapy and decrease the extra-cost of the treatment for ADEs. In the future, increasing utilization of this concurrent CSS should have an enormous beneficial impact on the quality of medical care.

Depression is a disease with an increasing prevalence worldwide, and is highly associated with mortality as well as several diseases such as hypertension. The aim of this study is to discover clinical risk indicators associated with depression in the occupational group of simple labor workers. This study used the Seventh Korean National Health and Nutrition Examination Survey (2016-2018) conducted by the Korea Centers for Disease Control and Prevention. In association between depression and demographic information, age, sex, degree of stress perception, and stress perception ratio indices had a very high statistical association with depression, and education level and marital status were also associated with depression. Obesity indices such as abdominal circumference and body mass index were not associated with depression. Among the blood information, hemoglobin and hematocrit were highly associated with depression, and statistical significance was maintained even in the analysis adjusted for sex and age. The results of this study can be used as information for the prevention and treatment of depression in the occupational group of simple labor workers in the future.

The mortality of left ventricular free wall rupture after acute myocardial infarction is high; however, subactue myocardial rupture can be diagnosed by echocardiogram and the use of the intraaortic balloon pump reduces the incidence of re-rupture. Bleeding from subacute myocardial rupture can be managed by employing fibrin glue and several patches. We report here on a case of successfully managed case of subactue left ventricular free wall rupture after acute myocardial infarction with using the sutureless technique and fibrin glue.

Recently, AI, big data, and IoT technologies are being used in various solutions such as fire detection and gas or dangerous substance detection for safety accident prevention. According to the status of occupational accidents published by the Ministry of Employment and Labor in 2021, the accident rate, the number of injured, and the number of deaths have increased compared to 2020. In this paper, referring to the dataset construction guidelines provided by the National Intelligence Service Agency(NIA), the dataset is directly collected from the field and learned with YOLOv4 to propose a collision risk object detection system through object detection. The accuracy of the dangerous situation rule violation was 88% indoors and 92% outdoors. Through this system, it is thought that it will be possible to analyze safety accidents that occur in industrial sites in advance and use them to intelligent platforms research.

As of 2020, 1,564 roundabouts have been installed and operated to prevent major traffic accidents and promote safe and smooth passage over the past 10 years. According to the Korea Transportation Research Institute, the number of accidents decreased by an average of 43.8% per year, fatal accidents by 50%, and serious injuries by 48.1%, confirming the safety effect. However, most intersections with high pedestrian traffic, such as children's protection areas near elementary schools, operate signal intersections. Therefore, in this study, a simulation was performed through the VISSM program to conduct a study on the pedestrian-centered roundabout installation method. This study was conducted to ensure that pedestrians can have the right of way safely by installing and operating traffic lights at crosswalks on roundabouts located in urban areas or child protection zones.

It has been found that the incidence and mortality of COVID-19 are high in patients with underlying chronic diseases. Amid COVID-19 pandemic, tooth brushing is as important as hand washing for health care. The aim of this study was to identify factors related to the rate of tooth brushing and hand washing in hypertensive patients. We analyzed 62,762 hypertensive patients over the age of 40 from the Community Health Survey 2020. The practice rate of hand washing was higher among women, younger age, higher education level, mask wearers when going out, and tooth brushing practitioners after lunch. The hand washing practice rate was higher in hypertensive patients who practiced tooth brushing. In conclusion, there was the relationship between oral hygiene and personal quarantine. It is necessary to prepare sustainable measures to increase the practice rate of infectious disease prevention behaviors for patients with underlying chronic diseases who are susceptible to COVID-19.
