Purpose: This study investigated the patient safety culture (PSC), the perception of importance on patient safety management (PIPSM) and the patient safety management activities (PSMA) of care workers in nursing homes. This was a descriptive study that attempted to provide basic data for the patient safety education program of care workers. Methods: Data were collected using questionnaires and interviews from July 1 to 31 in 2020. One hundred and seventy-four care workers participated in quantitative research. The collected data were analyzed by the SPSS/WIN 25.0 program using descriptive statistics, t-test, ANOVA, Bonferroni, and Pearson's correlation. The qualitative data were collected through semi-structured, audio-recorded interviews with six representatives and six care workers from six nursing homes. Content analysis was performed to analyze the data. Results: Positive correlations were observed between PSC and PIPSM, and between PIPSM and PIPSM. Care workers' experience in patient safety management was in the following six categories: "Safety accident risk factors", "Type of safety accidents", "How to prevent safety accidents", "Effective safety management education", "Emphasis on occupational ethics of care workers", and "Needs for standard protocol" Conclusion: These findings indicate that considering the care workers' age and facility size, nurses should enhance patient safety education for care workers and establish a management activity system.

Recently occupational safety and health literatures begin to emphasize the influence of social, organizational or psychological context. Based on this research trend, this paper tried to review the relationship between safety climates and safety compliance. Based on the responses from 385 manufacturing workers, this paper reviewed the relationships among safety climates, safety motivation, and safety compliance. The results of statistical analysis showed that all safety climate factors(management involvement, leadership, safety training, precaution activities, safety system) have affirmative effects on safety motivation and safety compliance. Also, safety motivation appeared to have mediating effects on the relationship between 5 safety climate factors and safety compliance. Especially it appeared to have full mediating effects on the relationship between safety training/ safety system and safety compliance.

The purpose of this study was to develop a patient safety nursing activities scale for clinical nurses and to verify validity and reliability it. A preliminary scale was developed through various processes and pilot study. Data were collected from 900 nurses at 28 hospitals selected by proportionate stratified sampling with 331 general hospitals nationwide. The final scale was a 4-point scale, consisting of 72 items in 10 domains. The construct validity was found to be appropriate by exploratory factor analysis and 70.3% of the variance in the total scale and over .74 of factor loading. There was a significant correlation between scale and patient safety culture (r=.52, p<.001) and Cronbach's ${\alpha}$ was .99. This scale developed to measure patient safety nursing activities of clinical nurses was found to be reliable and valid and will be a useful tool in practical field.

The possible tumor-promoting activities of sodium chloride (NaCl) and dimethyl itaconate (DMI), one of the quinone reductase inducers, were examined on stomach of male Wistar rats treated with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Administrations of NaCl and DMI after the initiation by MNNG resulted in various sized masses in the rat forestomach. Histopathologic studies showed that the combination of NaCl and DMI made an enhancing effect on the MNNG-induced carcinogenesis, resulting in papilloma in 5 weeks and squamous cell carcinoma in 20 weeks in submucosal area of forestomach. We also used an in vivo shortterm method for evaluating possible tumor-promoting activity with ornithine decarboxylase (ODC) as a marker. The markable inductions of the ODC activities by MNNG, NaCl, and DMI were found in the pyloric mucosa of rat stomach in time-dependent manners. A single administration of MNNG induced ODC activity up to 288 pmol $CO_2$/hr/mg protein at 24 hr after the administration. NaCl caused induction of ODC with a maximum of 179 pmol $CO_2$/hr/mg protein at 8 hr after the administration. ODC was induced up to 539 pmol $CO_2$/hr/mg protein at 16 hr after the administration of DMI. Additional treatment of NaCl and NaCl plus DMl caused 2 fold and 7 fold increases, respectively, in the ODC activity of the MNNG-alone group at 24 hr after the administration. These results suggest that NaCl and DMI have promoting activities in the rat gastric carcinogenesis initiated by MNNG.

Followed by government authorized data that Ministry of Education submitted, safety accident at school has been increased year by year. Safety accident occurred 33,834 in 2005, 29,955 in 2004, and 22,722 in 2003. It shows that it has been increased about 12.9% from 2004 and 48.9% in 2003. Level of student's development, students are at the point of not having enough judgement and ability to adapt at emergency situation. They are learned about safety by education and management by teachers but teachers will get heavy burden and anxiety if government doesn't provide more improved support and restraint. On this situation, educational authority can be attacked and it legally charged by nation, owned property can be loss or prosecution can be occurred. Also school safety accident which occurs in these days is working as an negative insecurity element that teachers cannot concentrate on the education.

Zohar(1980) emphasized the influence of social, organizational, and psychological context in occupational safety and health study. With this research trend, Neal, Griffin, and Hart(2000) developed a sequential safety climate model. In this paper, author examined the usability of their model the relationships among safety climates, safety knowledge, safety motivation, and safety performance(safety compliance and safety participation). The author conducted a survey to 207 manufacturing workers, and the chief results of statistical analysis are as follows : 1) the leadership has positive effects on safety knowledge and motivation, 2) the precaution activities has only positive on safety knowledge, 3) the safety system has only on safety motivation, 4) the safety knowledge and motivation have positive effects on safety compliance and participation.

The paper provides the approach to apply formal methods to the development and certification criteria of defense safety/security-critical software. RTCA/DO-178B is recognized as a do facto international standard for airworthiness certification but lack of concrete activities and vagueness of verification/certification criteria have been criticized. In the case of MoD Def Stan 00-55, the guidelines based on formal methods are concrete enough and structured for the defense safety-related software. Also Common Criteria Evaluation Assurance Level includes the strict requirements of formal methods for the certification of high-level security software. By analyzing the problems of DO-178B and comparing it with MoD Def Stan 00-55 and Common Criteria, we identity the important issues In safety and security space. And considering the identified issues, we carry out merging of DO-178B and CC EAL7 on the basis of formal methods. Also the actual case studies for formal methods applications are shown with respect to the verification and reuse of software components.
