The purpose of this study was to evaluate microbiological contamination of knives and cutting boards in child-care centers. Materials used in this study were swabbed of cutting boards and knives (blade, handle of knife, and joint of handle and blade) in 129 child-care centers. Mean values of total aerobic bacteria of swabs of knives and cutting boards were 1.7±0.7 log cfu/100 cm2 and 1.7±0.9 log cfu/100 cm2, respectively. Contamination levels of coliform bacteria from knives and cutting boards were 1.5±0.6 log cfu/100 cm2 and 1.7±0.8 log cfu/100 cm2, respectively. Comparing microbiological contamination levels of knives and cutting boards according to type and size of child-care centers, there was no significant difference. Bacillus cereus was detected in knife handles and cutting boards. Diarrhea-type toxin gene (entFM) was detected in B. cereus isolates. Antibiotic resistance tests showed that B. cereus was resistant to β-lactam antibiotics. To reduce microbiological contamination levels of knives and cutting boards in child-care centers and prevent food poisoning from bacteria contamination, continuous education by children's food-service management center is needed for sterilization and disinfection of knives and cutting boards.

A forklift accident occurs in the logisitcs center. there are many kinds of accidents such as a casualty accident or a minor accident, etc. there are many other causes of accident, including poor　visibility and habitual operational mistakes The result of the accident is the phenomenon of cutting, falling,　scratching of the product. In the case of minor accidents, workers do not report accidents, so the occurrence of accidents is unknown. The customer receives the goods and then notifies them that they are defective product. After the product is returned, we can see that the forklift accident caused the problem of the product The result of the late response affects the image of the enterprise. In this study, we recognized the need for safety education to prevent accidents and found out which of the education items could raise awareness of safety. As result of the study, disinfection and forklift maneuverability regarding speed were mentioned as the most important items in education.

The purpose of this study is to understand how to affect the safety behavior to the organization's trustees to investigate the level of safety awareness, safety awareness via the distribution center workers prepare the logistics industry disaster prevention measures. The survey was analyzed data to target by the clothing distribution center employees of 182 people. Analysis First, the level of safety awareness showed on a positive effect on organization trust. Second, it was found on the safety level of consciousness a positive effect on the safety behavior. Third, the level of safety awareness affect the safety behavior showed that the mediating role of organization trust. That is a higher level of safety awareness, such as the strict practice of business activities, investments, safety rules on safety education and training emphasis on safety increases confidence in the organization. It was confirmed the higher the confidence in the safety organization appears behavior such as actively participating in the work carried out in a safe manner, safety education and training. In addition, the effect was mediated by the organizational impact on confidence in the safety of personnel safety awareness actions. Based on that research results prepared safety awareness was raised through the industrial accident prevention measures

This study was aimed to demonstrate how the analysis of the impact on confidence in the safety-conscious organizations target the clothing distribution center employees and organizational commitment. Safety awareness of employees of the clothing distribution center safety rules, safety education, road safety interests, divided into risk handling and trusted organization with the emotional trust and cognitive trust, organizational commitment was divided into affective, cognitive and normative commitment. Data collection was surveyed 185 people clothing distribution center workers, tested the hypothesis through regression analysis. The results are safety conscious exerts a positive effect on organizational trust, organizational trust was found to have a positive impact on organizational commitment.

우리나라는 1953년 창경호(사망 300여명)을 시작으로 1970년 남영호(사망 326명), 1993년 서해훼리호(292명), 2014년 세월호(사망 295명, 실종 9명) 사고가 발생했다. 반복되는 대형 해양사고에도 불구하고 정부나 국민의 안전의식은 여전히 저조한 실정이다. 이 연구는 국민들의 안전의식 고취를 위해 해양안전체험장의 도입과 대형 해양사고 발생 시 수색ㆍ구조 기관에 신속히 자문해 줄 수 있는 안전연구센터의 설립의 필요성에 대해 제안한다.

구급의 발전에 있어서 여성구급대원의 역할이 크다. 여성구급대원의 근무환경과 스트레스 경감을 위하여 대화를 통한 소통이 필요할 것이다. 여성이라는 이유만으로 불평등한 근무형태와 남자와 같은 근무조건을 강요한다는 것은 후진국의 형태이다. 경상북도 여성구급대원의 스트레스에 관한 내용은 시간이 지나면 개선이 되고 바뀌어 갈 것이다. 앞으로 여성구급대원의 역할 또한 더 중요해지고 강조되어 질 것으로 생각하고 있는 것으로 조사되었다.

This research fundamentally deals with an analysis of service level for a multi-level inventory distribution system which is consisted of a central distribution center and several branches being supplied stocks from the distribution center, Under continuous review policy, the distribution center places an order for planned order quantity to an outside supplier, and the order quantity is received after a certain lead time. Also, each branch places an order for particular quantity to its distribution center, and receives the order quantity after a lead time. In most practical distribution environment, demands and lead times are generally not fixed or constant, but variable. And these variabilities make the analysis more complicated. Thus, the main objective of this research is to suggest a method to compute the service level at each depot, that is, the distribution center and each branch with variable demands and variable lead times. Further, the model will give an idea to keep the proper level of safety stocks that can attain effective or expected service level for each depot

The purpose of this study was to identify vulnerable area of emergency medical care. In the existing method, the emergency medical vulnerable area is set as an area that can not reach the emergency room within 30 minutes. In this study, we set up an area that can not reach within 30 minutes including the accessibility of 119 emergency center. To accomplish this, we obtained information on emergency room and 119 emergency center through Open API and constructed road network using digital map to perform accessibility analysis. As a result, 509 emergency room are located nationwide, 78.0% of them are concentrated in the region, 1,820 emergency center are located, and 61.0% of them are located in rural areas. The average access time from the center of the village to the emergency room was analyzed as 15.3 minutes, and the average access time considering the 119 emergency center was 21.8 minutes, 6.5 minutes more. As a result of considering the accessibility of 119 emergency center, vulnerable areas increased by 2.5 times, vulnerable population increased by 2.0 times, and calculating emergency medical care vulnerable areas, which account for more than 30% of the urban unit population, it was analyzed that it increased from 17 to 34 cities As a further study, it will be necessary to continuously monitor and research the real-time traffic information, medical personnel, medical field, and ambulance information to reflect the reality and to diagnose emergency medical care in the future.
