A type certificate is required to ensure the safety of aircraft design. If a person is to pursue major design change to the certified aircraft, an applicant has to apply for a new type certificate, an amended type certificate, or a supplemental type certificate appropriately. Design changes to be applied for a supplemental type certificate are abstractly defined in ICAO, FAA, and EASA regulations. In this paper, authors reviewed certification procedures regarding design changes, analysed certification examples of leading countries, and presented the criteria to determine "major design changes not extensive" for a supplemental type certificate.

In order to verify that a lot of legal requirements and regulations are correctly translated into software, this paper provides a solution for formal and computable representations of rules and requirements in data protection legislations with a DSML (Domain Specific Modeling Language). All policies are formally specified through Prolog and then integrated with DSML, According to the time of policy verification, this solution has two kinds of policies: static policies, dynamic policies.

PURPOSES : Road sectors contribute approximately 16 % of total GHG emission rates in South Korea. Engineers and experts expend significant efforts to identify countermeasures for the reduction of carbon emission. This study aims to determine how total carbon emission rates change depending on whether or not there is speed limit enforcement. METHODS : In this study, Lamm's travel speed profile theory is first adopted to select the hazard road, which sections are designated as speed limit enforcement. Second, Motor Vehicle Emission Simulator (MOVES) was used to simulate the carbon emission on the road. RESULTS : The total carbon emission rate under speed limit enforcement was 10,773 g higher than the condition without speed limit enforcement in the designated road. This might affect acceleration, which can lead to increased emissions. CONCLUSIONS : There would be no researches about proving the relationship how speed limit enforcement has an effect on carbon emission. The result of our study can provide valuable guidelines regarding road safety and eco-friendly roads.

The right to the spectrum frequency and orbit is required for the broadcasting by satellite, whether the broadcaster might be given any license or authorization for the broadcasting. The reason is that the ITU Convention and Radio Regulation provide very specific and detailed rules regarding the utilization of the frequency spectrum and orbit. Outstanding issue arises as to the implementation process of the rules of international character. Domestic implementation of the Radio Regulation, in the way of letter to letter should be discouraged when the competitiveness of domestic industry vis-a-vis foreign competitor is taken into account.

The majority of financial institutions are complying with the ratio of the total number of IT staff to total IT regulatory regulations, regardless of the size of the financial institutions and the scope of the information security work. The risk is spreading as a result of the information security workforce neglect their own work because of having multiple tasks. In this study, we propose a method to estimate the number of workforce needed in consideration of the size of financial companies and the characteristics of information security work, and to establish a systematic information security organization to respond more effectively to financial security accidents.

In the past, when the personal information leakage incident of the three card companies, the computer program development was followed by the same strict electronic financial supervision regulations as the operating environment. However, when developing a computerized program, the application data is being verified with the integrity of the test data being compromised because the identification of the scope of conversion of the test data associated with the application is unclear. Therefore, in this paper, we proved by presenting a process and algorithm for selecting a range of sufficient test data conversion targets associated with a specific application.

This paper shows secure coding rules for PHP programs. Programmers should comply with these rules during development of their programs. The rules are crafted to restrain 28 weaknesses that are composed of 22 corresponding to reported CVEs of PHP, the children of CWE-661 for PHP, and the top 5 weaknesses according to OWASP. The rule set consists of 28 detailed rules under 14 categories. This paper also demonstrates through examples that programs complying with these rules can curb weaknesses. The rules can also serve as a guideline in developing analysis tools for security purposes.

Recently, Syntheic data has been in the spotlight as a technology that can protect personal information while maintaining the patterns and characteristics of actual data. Accordingly, technical and institutional research on synthetic data is actively being conducted, but it is difficult to actively use synthetic data due to the lack of clear standards and guidelines. This study is a preliminary study for quantifying the disclosure risk of synthetic data, and derives a privacy disclosure risk index through statistical methodology and suggests specific application measures to comply with the General Data Protection Regulation(GDPR). It is expected that the disclosure risk and the balance of data utility can be controlled through the privacy disclosure risk index of this study in an open data environment.

In this paper, a disposal maneuver which complies the space debris mitigation guideline was analysed for KOMPSAT-2 as an example of LEO satellite. Definition of disposal altitude which comply the '25 year rule', re-entry survivability analysis of KOMPSAT-2 parts inside and casualty area analysis were performed using STK and ESA's DRAMA. Finally, assuming that there were several survival objects during uncontrolled re-entry stage, the re-entry initial orbit elements which show the low casualty probability were found even if there were various uncertainties about the initial orbit. As a result, KOMPSAT-2 should be descended its altitude at least 43km or up to 105km to comply '25 year rule' and there were heavy or heat resistant survival objects which generated $4.3141m^2$ casualty area. And if RAAN of re-entry initial orbit was 129 degree, total casualty probability was lower than standard value of space debris mitigation guideline even if there were uncertainties about the initial orbit.
