  • Human errors are now considered as the most significant source of accidents or incidents in large-scale systems such as aircraft, vessels, railway, and nuclear power plants. As 61% of the train accidents in Korea railway involving collisions, derailments and fires were caused by human errors, there is a strong need for a systematic research that can help to prevent human errors. Although domestic railway operating companies use a variety of methods for analyzing human errors, there is much room for improvement. Especially, because most of them are based on written papers, there is a definite need for a well-developed computerized system supporting human error analyzing tasks. The purpose of this study is to propose a framework for a computerized human error analysis system focused on the railway industry on the basis of human error analysis mechanism. The proposed framework consists of human error analysis (HEA) module, similar accident tracking (SAT) module, cause factor recommendation (CFR) module, cause factor management (CFM) module, and statistics (ST) module.

  • Coronary vasospasm is one of the fatal complications that may occur in patients undergoing open heart surgery. To date, however, there are not many cases in this series and no definite pathophysiology has been documented. We experienced a case of coronary artery vasospasm after atrial septal defect (ASD) surgery and then successfully treated it with both transbrachial intraaortic balloon pump and percutaneous cardiopulmonary support. Only several hours after ASD surgery, the patient exhibited the cardiovascular collapse, the ST-segment elevation, followed by ventricular fibrillation and normal coronary angiography findings. It is important to make a differential diagnosis of coronary artery vasospasm in patients presenting with ST-segment elevation who had no notable coronary artery diseases. This case indicates that clinicians should be aware of the possibility that the coronary artery vasospasm may also occur in patients undergoing ASD surgery.

  • In infrapatellar bursitis, an acute or chronic inflammation of the infrapatellar bursa causes pain and swelling at the front of the knee. To date, only a few studies have reported cases of infrapatellar bursitis that are treated using Korean medicine. The aim of the present study is to report a case of a 27-year-old male with front knee pain caused by infrapatellar bursitis that was treated with integrated Korean medicine treatments (e.g., acupuncture, pharmacopuncture, herbal medicine). The patient-reported numeric rating scale confirmed that the patient's pain was relieved, while the physical function tests also indicated a significant improvement. Based on the findings of this study, it can be suggested that integrated Korean medicine treatments could be an effective therapeutic option for patients diagnosed with infrapatellar bursitis.

  • The triangular fibrocartilage complex (TFCC) is crucial for stabilizing the ulnar side of the wrist but can be partially torn due to degenerative changes, falling, or sudden injuries. However, only a few studies have focused on the use of Korean medicine treatments for TFCC-related wrist pain. This case report presents the successful outcomes of integrated Korean medicine treatment in a patient with a partial TFCC tear. The diagnosis was confirmed via magnetic resonance imaging, which revealed the tear. Subsequently, the patient received integrated Korean medicine treatments. The assessment of the pain scale scores revealed a significant reduction in wrist pain and an improvement in daily life activities. Based on the findings of this study, integrated Korean medicine treatments have been proven to be an effective treatment option for patients with a partial TFCC tear. However, further research is needed to determine the potential benefits and mechanisms of these treatments in managing TFCC-related wrist pain.

  • Objectives : This study was designed to investigate anti-obesity effects of DF in a ob/ob mouse model. Methods : Fifteen-week-old ob/ob mice were divided into four groups: a normal lean group given a standard diet, an ob/ob control group given a standard diet, and DF(1) and DF(2) groups given a standard diet with DF(1) (300 mg/kg), and DF(2) (600 mg/kg), respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : Body weight gain and fat mass were significantly decreased in DF(1) and DF(2) groups compared with control. The extent of decreases was eminent in DF(2) group. Feeding efficiency ratio were significantly decreased in DF(2) group compared with control. Consistent with their effects on body weight gain and fat mass, circulating concentrations of LDL, total cholesterol, free fatty acid, and insulin were decreased in DF(2) group compared with control. The size of adipocytes were significantly decreased by DF(2) compared with control. Consistent with their effects on body weight gain, hepatic lipid accumulation and liver weights were reduced in DF compared with control. Conclusions : In conclusion, these results suggest that DF not only decrease feeding efficiency ratio, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF also inhibits hepatic lipid accumulation.

  • Objectives : Methicillin-resistant Staphylococcus aureus (MRSA) has a cephalosporin and beta-lactam antibiotic-resistant strains. MRSA is one of the major pathogens causing hospital infection and the isolation ratio of MRSA has gradually increased. Consequently, increased resistance to antibiotics is causing serious problems in the world. Therefore, there is a need to develop alternative antimicrobial drugs for the treatment of infectious diseases. Methods : The antibacterial activities of Ipyo-san were evaluated against 2 strains of MRSA and 1 standard Methicillin-susceptible staphylococcus aureus (MSSA) strain by using the disc diffusion method, minimal inhibitory concentrations (MIC) assay, colorimetric assay using MTT test, checkerboard dilution test and time-kill assay performed under dark. Results : The MIC of Ipyo-san water extract against S. aureus strains ranged from 1000 to $2,000{\mu}g/ml$, so we confirmed that it had a strong antibacterial effect. Also, the combinations of Ipyo-san water extract and conventional antibiotics exhibited improved inhibition of MRSA with synergy effect. We suggest that Ipyo-san water extract against MRSA has antibacterial activity so it has potential as alternatives to antibiotic agents. For the combination test, we used Triton X-100 (TX) and DCCD for measurement of membrane permeability and inhibitor of ATPase. As a result, antimicrobial activity of Ipyo-san water extract was affected by the cell membrane. Conclusions : We suggest that the Ipyo-san water extract lead the treatment of bacterial infection to solve the resistance and remaining side-effect problems that are the major weak points of traditional antibiotics.

  • This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their behaviors by measuring the level of self-efficacy and consciousness on the use of radiation, knowledge and attitude on radiation safety management(RSM). The subjects were 235 of the dental hygienists and this study performed a survey 8 May to 17 June, 2011. The survey results were as follows. 1. As a result of comparing the average of the self-efficacy according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to health condition, protection facilities condition. 2. As a result of comparing the average of consciousness about radiation use according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to medical institute type, protection facilities conditions. 3. As a result of comparing the average of the behaviors for RSM according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to monthly income, medical institute type, whether or not education on radiation was conducted, the number of education, education type, and protection facilities condition. 4. As a result of analyzing what factors have an influence on the behaviors for RSM by employing the points of those behaviors as a dependent variable and self-efficacy, consciousness, knowledge and attitude as an independent variable in order to investigate those factors, it turned out that the factors which had a relatively larger influence on the point of behaviors were attitude and self-efficacy by that order(p<0.05). In conclusion, we believe that a variety of programs should be offered to provide knowledge on RSM as a prerequisite for improving the level of RSM behaviors by dental hygienists.
