In the organizational setting of marine engineering,a significant number of information security incidents have been arised from the employees’failure to comply with the information security policies(ISPs).This may be treated as a principal-agent problem with moral hazard between the employer and the employee for the practical compliance effort of an employee is not observable without high cost-.On the other hand,according to the deterrence theory,the employer and the employee are inherently self-interested *** is worth examining to what extent the employee is self-interested in the marine ISPs compliance ***,it is important to clarify the proper degree of severity of punishment in terms of the deterrent *** this study,a marine ISPs compliance game model has been proposed to evaluate the deterrence effect of punishment on the non-compliance behavior of employee *** is found that in a non-punishment contract,the employee will decline to comply with the marine ISPs;but in a punishment contract,appropriate punishment will lead her to select the marine ISPs compliance effort level expected by the employer,and cause no potential backfire effect.

Synthetic Aperture Radar Interferometry (for short, InSAR) is a new kind of earth observation technology, which has obtained great development in recent ten years and has a great development potential and successful future. In this note, three typical regions with different physiognomies and terrains have been selected as study regions to extract their Digital Elevation Model (OEMs). Compared with the existing 1 : 250000 DEM and by analyzing their results, we have obtained its accuracy and applicable scopes. The results show that in the region (plains, mountains or highlands) with dry surface and sparse vegetation, because of the better correlatability of images, the DEM obtained by InSAR is evidently better than the existing 1 : 250000 DEM and the accuracy can reach 4-6m; in the thick-vegetation-covering region, correlatability between images descends and the accuracy of InSAR DEM can only reach about 30 m worse than its existing 1:250000 DEM; in the middle covering field, the accuracy of InSAR DEM

In this paper, a series of C-terminal modified analogs of endomorphin-2 is investigated using ESI-FT-ICR-MS. Some b, y″, a, and internal ions are found in the CID spectra and slight mass differ- ences between the calculated and observed results are obtained. Moreover, if the C-terminal modified group is t-butyloxy, it can lose butene through McLafferty rearrangement. FT-ICR MS shows its power in peptide sequencing successfully helping us obtain the structure of peptide analogs.
