There are many accident risks in logging operation of forestry such as struck by felled trees and caught in, under, or between felled trees. These accidents are primarily occurred by not keeping a safe distance between workers. According to the forestry safety instruction, workers are not supposed to go into the safety zone which is a circle with a radius of more 2 times the height of felling tree. However, this rule does not keep because of poor safety consciousness, poor sight and extreme noise of logging operation machines. This problem causes many major accidents every year. To solve this problem, we made forestry safety helmets based on IoT technology. These helmets have functions to make a visual and an acoustic alarm signal when reach the distance between workers within 20 meters. We developed the algorithm to operate the helmet's functions and conducted tests to check the functions. As a result of tests, we assured the normal system operating conditions.

A food allergy is described an adverse immunological reaction to a food item. It is increasingly common problem among infants, children, teenagers, and adults worldwide. This study examines food allergy knowledge, attitudes, practices, and health consciousness among college students studying food and nutrition and childhood education. A total of 235 food and nutrition and childhood education college students participated in the survey. According to the results, 41.3% of the respondents were aware of legal obligations associated labeling food items for food allergy; 14.0% were diagnosed with food allergy by their doctor; and 10.2% knew about food allergy symptoms. Food and nutrition students were more knowledgeable than childhood education students. The mean for food allergy attitudes was 4.22, and the score for food and nutrition students was higher than that for childhood education students. The mean for food allergy behaviors was 2.16, and the score of food and nutrition students was higher than that of childhood education students. The importance of food allergens was significantly higher than performance. These results suggest that, to improve the management of food allergies in foodservice operations, education programs regarding food allergies should be provided food and nutrition and childhood education students.

Background: Lumbar epidural steroid injection for relief of low back pain and sciatica has become a popular procedure. further, cervical epidural steroid injection with nerve block (CESNB) is known to be effective for the management of acute and chronic pain of neck, shoulder and arm. However, many anesthesiologists are not familiar with CESNB. Methods: Charts of 34 patients who had undergone 60 cervical epidural steroid injections over a three year period, 1993 to 1995, were reviewed. We studied the followings: initial visit and department, injected interspaces, personal characteristics, indications for injection and complications. Results: Patients' first visits were mainly to orthopaedics (11 patients) and neurosurgery (10 patients). Epidural injection sites were: C7-T1 interspace (29 patients) and C6-C7 interspace (6 patients). Mean age of patients were 50.1 years. range 21~73 years. There were twenty male and fourteen female patients. Complications varied from dizziness after CESNB (1 patient). loss of consciousness with transient apnea (2 patients), and local infection with suspicious meningitis (1 patient). Conclusion: We conclude from the above data that CESNB is a good, safe and conservative form of therapeutic procedure in the management of patients suffering from cervical radiculopathy, and neck and shoulder pain.

A patient presented with loss of consciousness and conversion. During an exercise test, catecholaminergic polymorphic ventricular tachycardia (CPVT) resulted in cardiac arrest. He started taking medication (a beta-blocker and flecainide) and an implantable cardioverter defibrillator (ICD) was inserted, but the ventricular tachycardia did not resolve. Left cardiac sympathetic denervation (LCSD) was then performed under general anesthesia, and the patient was discharged on the second postoperative day without complications. One month after the operation, no shock had been administered by the ICD, and an exercise stress test did not induce ventricular tachycardia. Although beta- blockers are the gold standard of therapy in patients with CPVT, thoracoscopic LCSD is safe and can be an effective alternative treatment option for patients with intractable CPVT.

According to the statistics of occupational accidents in 2009, the scaffolds and work platforms were main objects causing fall accidents in construction sites. But many workers install and use the work platforms on the mobile scaffolding without considering about safety standards. We had conducted a nationwide survey about how workers obey safety standards for the work platforms of the mobile scaffolding. As the result of a survey, no one follow a gap standard between materials of work platforms and installation of toe board. And it is a low proportion that comply with the install of safety guard rails and the use of stoppers. This is lack of consciousness for the safety certification and regulations. For safe use a mobile scaffolding, It is needed to educate a manager on the safety standards and to develop a product to install and dismantle easily.

In laboratories, researchers frequently work using new methods with new tools and materials. So the workers in laboratories are exposed to risk from dangerous articles all the time. In the case of university laboratories, testing is done by the individual at night. Because of that, the risks in university laboratories are higher than in other places. In addition, students and managers in universities generally have little concern for laboratory safety. So students are sometimes injured or killed in laboratory accidents. In this study, 1,000 university students answered questions about university laboratory safety. Their answers have been analyzed to determine the state of actual conditions and to formulate countermeasures. The results indicate that we need to change the safety awareness of the universities and the students. Adequate safety training and safe practice must be implemented by each university to decrease accidents. Development of systematic safety training program suited to the specific conditions of the individual laboratory and formulation of specific counter plans should accidents occur are required.

It is estimated that about 2,515 persons have been injured by conveyor for the past five years(2013 ~ 2017). Conveyors used in various industrial sites for transporting iron ore, coal, courier goods, etc., have various incidents such as a worker putting on or pulling a part of the body or work clothes on the driving part during maintenance. It is necessary for preventing similar accidents to conduct various researches. In order to propose the basis for revising laws and standards for the safety standards of the full cord switch to prevent conveyor accidents, this study compares Korea's Industrial Safety and Health Law (KISHL) with those of IEC, EN, Canada, and Australia. In addition, surveys of conveyor use plant and full cord switch domestic and foreign manufacturers was conducted. In this study, domestic and overseas related laws and technical standards compare and analyze to prevent conveyor accidents. In addition, we propose extension of safety certification for full code switch, establishment of safety inspection standard, and improvement of working method regulation through actual working condition investigation. It can be used as a basis for revising the occupational safety and health regulation and related notices, and thus contributing to enhancing the safe atmosphere of the conveyor business and improving the safety consciousness of the concerned persons.

This study has focused on the transfer of infants and Toddlers-protecting responsibilities from families to infants and Toddlers education agencies due to an increase of a double-income family and nuclear family. It is because there is insufficient safe play space from the moment when infants and Toddlers return from infants and Toddlers education agencies to home due to a high crowding of housing and increase of vehicle, and there can be difficulties to take responsibilities of infants and Toddlers safety with a mere recognition and effort of parent. Thus, to suggest a safety education through mutual contact between the communities and agencies supporting parent role in a level of social welfare, its potential has been identified through a frequency analysis on 60 participants of experimental group who have trained a safety education and 60 participants of control group who have not trained a safety education. As a result of frequency analysis, the increase in safety condition in Korea, safety and development of infants and Toddlers, safety of play materials, and safety knowledge on general part of facility safety has detected and the practice of safety and safety consciousness has also identified to be more effective. The results of this study has shown a potential to verify its efficacy if it is verified through an elaborative model of safety education based on parents of young infants and Toddlers family.

The Fontan operation is a heart operation used to treat complex congenital heart defects like tricuspid atresia, hypoplastic left heart syndrome, pulmonary atresia and single ventricle. A single ventricle is dedicated to pumping oxygenated blood to the systemic circulation and the entire systemic venous return reaches the pulmonary arterial system without the direct influence of a pumping chamber. In the patient with Fontan operation, it is important to achieve adequate pulmonary blood flow and cardiac output in anesthetic management. In this case, a 10-year-old boy (19.6 kg, 114 cm) with cleft palate, cerebral palsy and severe mental retardation, who underwent a Fontan operation when he was 4 years old, was presented for deep sedation. Because he was suffering from eating disorder with cleft palate, the orthodontist and the plastic surgeon planned to insert intraoral orthodontic device before cleft palate repair. But it was impossible to open his mouth for alginate impression procedure. After careful pre-anesthesia evaluation we planned to administer deep sedation with propofol infusion. After Intravenous catheter insertion, we started propofol intravenous infusion with the formula of a loading dose of 1.0 mg/kg followed by an infusion rate of 6.0 mg/kg/hr with syringe pump. His blood pressure was remained around 80/40 mmHg after loss of consciousness, but he could not maintain his airway patent. So we lowered the infusion rate to 3.0 mg/kg/hr, immediately. The oxygen saturation was maintained above 95% with nasal oxygen supply, and blood pressure was maintained around 100-80/60-40 mmHg. After the sedation of 110 minutes with propofol (the infusion rate to 3.0-5.0 mg/kg/hr), he fully regained consciousness, and was discharged without complication after 1 hour observation. In case of post-Fontan patient, intravenous deep sedation with propofol was safe and effective method of behavioral management during dental treatment.
