Because of development of printing technology, toner cartridge particle becomes smaller and more dangerous. And sometimes we had incidents with dust explosion of toner cartridge particle at recycling facilities in Japan. Therefore we studied on hazard of toner particle relating with dust explosion. We found that toner particle is so dangerous compared with most organic solids, even though it does not belong to hazardous materials in the UN regulation and the Japanese Fire Service Law.

Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

Objective: The objective of this research is to inquire about safety information from the standpoint of its usefulness to suggest the significance of the Reactive Safety Action Program, which serves to promote aviation safety culture. Background: Safety information plays an important role in operating safety programs. Each organization learns lessons from safety information collected from aviation accidents and incidents. When an accident occurs, it is only through safety investigation and a close inquiry on the cause that we can come up with an appropriate countermeasure which would contribute to preventing the recurrence of the same or similar accident. However, the usefulness of safety information produced from unsatisfactory safety investigation is insufficient. Method: This research analyzed the characteristics of aviation accidents, the differences between safety investigations and legal accident investigations in systematic and operative perspectives, and safety culture as a measure to activate reporting systems (compulsory/voluntary). Results: This research defined the investigation scope and processes of safety investigations and legal accident investigations. It also suggested factors such as just culture based on trust, non-punitiveness, confidentiality, the participation of the entire staff through the use of inclusive reporting base, ensuring the independence of the operating organization as a way to promote safety through reporting systems. Conclusion: The organization's effort is the important aspect in obtaining exact and accurate safety information from accidents/incidents. The separate running of SIB (Safety Investigation Board) and AIB (Accident Investigation Board), the systematization of safety information reporting system, and prescribing (legislating) the composition of related organizations are some representative programs. Application: This research inquired experiences that contributed in promoting aviation safety culture in a reactive perspective, and will serve a role in spreading safety culture by enabling the use of application experiences of the aviation field in other domains.

Purpose: This study was designed to identify the factors affecting the nurses' experience of non-reporting adverse incidents in hospital. Methods: This study is a cross-sectional, descriptive survey design and nonrandom, convenience sampling. Study subjects were 392 clinical nurses, who have agreed to be the subject of this research. The measuring instrument of attitudes toward incident reporting was developed by the authors. The questionnaire which consisted of 17 items about worry about appraisal, the belief in improvement, the intention of reporting, and knowledge was measured by 5-point Likert-type scale. The estimate of internal consistency was alpha =.84. Analysis of data was done with use of mean, t-test, ANOVA, logistic regression with SPSS program. Results: Clinical nurses had experience of reporting incident (51.3%), non-reporting incident (76.5%). Statistically, significant differences were found between experiences group and non experience group in intention on reporting, belief on improvement, and worry about appraisal. Logistic regression analysis showed that the significant predictors were caused by report no-fault cases, belief on improvement, worry about appraisal. Conclusion: The result also indicated that, to improve the incident reporting and risk management, it might be necessary to give a belief that it results on improvement and remove concern about punishment through construction of no-blame system.

Recent accidents in school environment involving violence, and bullying indicate that school safety is exposed to a serious threat to community well-being. Such incidents come as big problem because various policies and programs have widely long been implemented in order to protect the school environment. Thus, it is critical for the local community and goverment to develop measures for prevention. However, some of the incidents are misrepresented because school environment still remains as one of the safest settings. The current study discusses successful case studies of education, policies and projects regarding school violence and safety that are enforced in many other nations. One of the most practical and concrete means of pursuing an improved level of school safety is for the local community to be actively involved in the process. And one of the key factors for the success of international programs was that it was very much an integrative approach involving a joint effort with the local communities, accompanying a strong tie between the school and its surrounding context.

With the rapid increase in the use of IoT and mobile devices, cyber criminals targeting IoT devices are also on the rise. Among IoT devices, when using a wireless access point (AP), problems such as packets being exposed to the outside due to their own security vulnerabilities or easily infected with malicious codes such as bots, causing DDoS attack traffic, are being discovered. Therefore, in this study, in order to actively respond to cyber attacks targeting IoT devices that are rapidly increasing in recent years, we proposed a method to collect traces of intrusion incidents artifacts from IoT devices, and to improve the validity of intrusion analysis data. Specifically, we presented a method to acquire and analyze digital forensics artifacts in the compromised system after identifying the causes of vulnerabilities by reproducing the behavior of the sample IoT malware. Accordingly, it is expected that it will be possible to establish a system that can efficiently detect intrusion incidents on targeting large-scale IoT devices.

As taking pictures by using smartphones has become more common in society, there are many incidents which are unexpected manipulation of images and leak of confidential information. Because of those incidents, demands that identify forgery/alteration of image file and proves of the original copy is constantly increasing. In general, smartphone saves image file as JPEG form and it has DQT which determines a compression rate of image in a header part of image. There is also DQT in Thumbnail image which inside of JPEG. In previous research, it identified a smartphone which take image by only using DQT, However, the research has low accuracy to identify the devices. There are two main purposes in this research. First, this research will analogize a smartphone and an application that takes a picture, edits and save an image file by testing not only about a DQT information but also a information of Thumbnail image. Second, the research will build a database of DQT and Thumbnail information in JPEG file to find more accurate image file's origin.
