Software verification and validation(V&V) is a means to develop high-quality software and assure safety and reliability for software. Also, we can achieve the desired software quality through systematic V&V activities. The software to be applied safety critical system like nuclear power plants is required to setup the V&V methodology that comply with licensing requirements for nuclear power plants and should be performed V&V activities according to it. In this paper, we classified safety-critical, safety-related and non-safety for software according to safety function to be peformed and define V&V activities to be applied software grade. Also, we defined V&V activities, procedures and documentation for each phase of software development life cycle and showed techniques and management to perform V&V. Finally, we propose the V&V framework to be applied software development of SMART(System-integrated Modular Advanced ReacTor) MMIS (Man-Machine Interface System) and to comply with domestic licensing requirements.

This study is a descriptive survey study for nurses in general hospitals to understand the effects of self-leadership, self-efficacy, and organizational commitment on safety management activities. The subjects of the study were nurses at three general hospitals located in G City. An online survey was conducted in consideration of the COVID-19 pandemic situation. Data collection was from August 20 to August 30, 2021. As a result of the study, self-leadership (r=.618, p<.001), self-efficacy (r=306, p<.001), organizational immersion (r=0518, p<.001) showed a positive correlation with safety management activities. In addition, self-leadership, self-efficacy, and organizational commitment explained 38.2% of safety management activities (F=20.478, p<.001). Therefore, it would be helpful to provide regular leadership education and self-efficacy education to increase patient management activities of general hospital nurses. In addition, if a positive work environment, legal standards for nurse work, and an appropriate compensation system are established to improve organizational commitment, it will have a positive effect on environmental safety management activities.

Railway signaling systems are so vital to ensure the safe operation of railroad and the assurance and demonstration of the safety is so important. The safety management process shall consist of a number of phases and activities, which are linked to form the safety life-cycle. The basic processes of safety management and safety activity throughout the lifecycle are 'risk analysis' and 'hazard control'. The safety managements and activities for the two kinds of aspects are implemented throughout the whole steps of system lifecycle. The risk analyses and hazard controls like those are needed, these activities have to be carried out through the whole of system lifecycle.

The antioxidant and cholinesterase inhibitory activities of the acetone and dichloromethane ($CH_2Cl_2$) extracts of the by-products (heads, shells, and tails) of Pandalus borealis, Pandalus hypsinotus, and Pandalopsis japonica belonging to the family Pandalidae were investigated and their bioactivities were compared. The antioxidant and cholinesterase inhibitory activities of the organic solvent extracts of three shrimp by-products were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis[3-ethylbenzothiazoline-6-sulfonic acid] ($ABTS^+$) radical scavenging activities, reducing power and xanthine oxidase (XO) inhibitory activity assays and Ellman's colorimetric method. The extracts of P. hypsinotus exhibited the highest antioxidant and cholinesterase inhibitory activities. The acetone extracts showed more potent activities toward antioxidant and cholinesterase inhibition compared with the $CH_2Cl_2$ extracts. Furthermore, the total carotenoid contents of the acetone extracts were higher than those of the $CH_2Cl_2$ extracts. Thus, the carotenoid contents may affect antioxidant and cholinesterase inhibition. Our results suggest that the shrimp by-products could act as a nutraceutical agent to prevent oxidative stress and Alzheimer's disease.
