Objectives: This study aimed to evaluate the relationship between oral health professionals' knowledge, attitude, and practice with regard to infectious waste management and to identify related factors influencing it. Methods: The study comprised of 219 oral health professionals from select dental clinics and public health centers recruited between August 25, 2016 and September 5, 2016, who agreed to participate in the study with full understanding of the study objectives. A self-reported questionnaire was administered, which consisted of 22 items on knowledge of infectious waste management, 9 items on attitude, and 16 items on practice. Data were analyzed using Pearson's correlation coefficient and stepwise multiple regression analyses. Results: The age, knowledge, and clinical attitude of oral health professionals significantly correlated with waste management practice. Specifically, infectious waste management practice improved with increasing age, a greater level of knowledge, and a more positive clinical attitude. Additionally, the standardized regression coefficient demonstrated that, of these three factors, clinical attitude more strongly correlated with effective waste management practice, followed by age and level of knowledge. Conclusions: These results indicated that oral health professionals had a low level of knowledge regarding infectious waste management, and a more positive clinical attitude resulted in better practices. Therefore, the development of detailed and active education guidelines and strategies are needed to enhance the attitude, knowledge, and practice of oral health professionals with regard to infectious waste management.

Recycling is a main issue in protection of the environment and waste collection and sorting have much higher value in current recycling policies than they did previously. Waste collectors, like firefighters and policemen, are working for the public benefit, however, waste collection is more dangerous than either police or firefighting work. In the USA, waste collectors are 10 times more likely than the average worker to die on the job. Waste collectors also suffer from musculoskeletal disorders, infectious diseases and various injuries. If we truly appreciate the worth of waste collectors, we need to improve their working environment and personal hygiene. Furthermore, abolishing discrimination will be a very important step towards greater protection for waste collectors.

The meat consumption produces a lot of bone waste everyday. Dumping bone waste without treatment results into environmental hazards. Conventional treatment by pyrolysis is slow, inefficient and produces hazardous by-products. In the work, an investigation of bone waste incinerated using thermal plasma technology is presented. A high temperature arc plasma torch operated at 33 kW was employed for the experiments. Bone waste was incinerated to remove the infectious organic matter and to vitrify the inorganic matter using plasma torch. Bone waste was reduced its 2/3 weight after the treatment. The process was highly efficient, economical, convenient, and fuel free. This method could be used as an alternative method for disposal of bone waste, small infectious animals, hazardous hospital waste, etc.

Purpose: This study was to provide baseline data to arrange systematic management for the infectious waste. Methods: This data was collected by self-reported questionnaires from a total of 419 subjects, ie nurses, nurse's aides and laboratory technicians working at a university hospital located in G city. The collected data were analyzed by t-test or ANOVA, Tukey test, Pearson's correlation, and multiple regression analysis using SPSS/WIN 12.0. Results: The knowledge of the infectious waste was statistically significant in type of staff and level of education. Attitude was statistically significant in type of staff, age group, level of education, working period, and marital status. And also the practice of the subject was statistically significant in type of staff, age group, education level, the working periods, and marital status. There was positive association between attitude and practice(r=.63, ${\rho}$< 001). By means of multiple stepwise regression analysis, total variance explained by the attitude towards infectious wastes, single employee, and the working periods less than ten years was 44% of the practice of infectious wastes. Conclusion: An educational program focusing on strategy to change employee's attitude can be effective for building a well-organized management system.

선진국과 달리 한국에서는 낮은 처리비용 등을 이유로 원거리에 있는 폐기물 처리시설에 의료폐기물 처리를 위탁하는 것이 가능하다. 이 과정에서 위험성 때문에 의원입법으로 개정법률안이 국회에 제출되어 있다. 본 연구는 선진국과의 비교연구를 통하여 의료폐기물 관련 문제해결을 위한 효과적인 방안을 모색하는데 그 목적이 있다. 연구방법은 문헌고찰 및 법률의 비교연구를 통한 서술식 방법을 채택하였다. 외국에서는 감염성 폐기물에 대하여 발생지 인근에서 신속한 처리를 원칙으로 하면서 장거리 이동 가능성을 제한하고 다양한 기술사용을 권장하고 있는 것에서 한국과 차이를 보인다. 따라서 외국 사례와 비교하여 의료폐기물 최적의 처리방안으로 권역화 방안을 제시했다.

본 연구에서는 의료폐기물에 대해 평상시 상황과 대규모 감염병 발병 상황으로 구분하여 발생 특성을 분석하였다. 평상시 상황에서는 회귀분석을 통해 의료폐기물 종류별 발생량 예측 모델을 수립하였으며, 유의값(p)은 모두 < 0.0001로 통계적으로 유의미하였다. 각 분류별 예측 모델식의 결정계수(R²) 값은 I-MW(R²=0.9943) > G-MW(R²=0.9817) > H-MW(R²=0.9310) 순으로 분석되었다. 또한, 기존 문헌과 유사한 결과로 영향인자로 사용된 GDP(G-MW), 의료기관 수(H-MW), 고령 인구비(I-MW)는 모두 높은 상관성을 나타내었다. 각 모델식을 종합한 총 의료폐기물 발생량의 MAE는 2,615, RMSE 3,353로 평가되어 H-MW(2,491, 2,890)와 I-MW(2,291, 3,267) 의료폐기물 모델식과 유사한 수준의 정확도를 나타내는 것이 확인되었다. 단기간 내 대량 발생하는 감염병 사태 시기의 의료폐기물 발생 특성은 정확한 추정이 제한적이므로 격리의료폐기물의 발생원단위를 분석하였다. 감염병 초기인 불안정기 8.74 kg/인·일, 안정기 2.69 kg/인·일, 감소기 시기 평균 0.08 kg/인·일의 발생원단위를 나타내었다. 격리의료폐기물 발생원단위와 치명률 간의 상관분석 결과, 불안정기 +0.99, 안정기 +0.52, 감소기 +0.96으로 나타났으며, 감염병 발병 전체시기에서 +0.95 이상의 매우 높은 양의 상관성을 나타내는 것이 확인되었다. 본 연구에서 도출된 연구결과는 보건 의료상에 적절한 의료폐기물 관리시스템을 구축하는 데 유용한 역할을 수행할 수 있을 것으로 기대된다.

최근 감염성폐기물에 의한 감염성에 대한 위험을 인식함에 따라 감염성폐기물의 관리 및 처리에 관한 문제점들이 사회적으로 부각되고 있다. 이에 본 논문에서는 차세대 핵심 기술인 RFID 기술을 이용하여 감염성폐기물의 발생원에서부터 처리장까지 일련의 과정을 실시간으로 모니터링이 가능하게 함으로써 감염성 폐기물의 비효율적인 처리로 인한 2차 감염 등의 문제를 해결하고자 하였다. 본 논문에서 제안하는 연구를 통해 기존의 현장 관리담당자에 의한 서면작성이나 웹 어플리케이션을 통해 처리되는 전산입력과 같은 관리방식에서 나타나는 오 기재 및 입력오류 등에 대한 문제점은 RFID 태그에 각 절차적 업무사항 저장하도록 하여 모니터링 함으로써 실시간으로 관리 현황을 파악할 수 있다. 그리고 개인인증을 위한 생체정보는 PCA 알고리즘으로 계산된 특징벡터를 인증용 태그 내에 저장하여 인증이 수행되도록 하였다. 이는 작업자가 폐기물을 취급 주의를 줌으로써 이전보다 체계적이면서 안전한 관리방안을 제안하였다고 하겠다.

This study investigated the relationship between knowledge of COVID-19, the risk of exposure to subjective infectious diseases, and the degree of infection control practices for dental personnel. For dental personnel currently working in dentistry, a survey consisting of 10 questions about COVID-19 knowledge and 63 questions about infection control practices was conducted. This study analyzed 126 survey data collected by distributing questionnaires form May 30 to June 20, 2020. Data was analyzed using t-test, ANOVA, and Pearson correlation. The average level of knowledge of COVID-19 was 5.44 out of 10, the average risk of exposure to infectious diseases was 3.86 out of 5, and the average level of infection control practices was 4.05 out of 5. The risk of exposure to infectious diseases was positively correlated with dental waste (r=.184). It was found that there was a significant positive correlation between infection control practices and sub-factors of infection control practices (p<0.001). To prevent the spread of COVID-19 and infectious diseases and to reduce the risk of exposure to infectious diseases for dental personnel, the practice of infection control should be improved. It is necessary to cultivate infection control experts and have mandatory infection control education and social regulations.
