The purpose of this study was to develop protective clothing that could alleviate fall impacts. Fall impact protection pants for elderly women were designed, and motion adaptable hip pads and knee pads printed by 3D printing were integrated into the pants and evaluated. First, the design of the fall impact protection pants with variable motion was semi-loose fitting pants that could be worn and detached from the protective pad. A pad pocket was made in the lining inside the pants so that the protective pad could be fixed to the protective area. Second, in the evaluation of the appearance of the fall impact protection pants, the wearer group had a good score of 4.60 or higher for all questions on color, material, ease, and fit. In the evaluation of the insertion method of the protective pad, the flexibility of the pad, and the weight of the pad, the subjects' scores were 4.30~4.80. The fit of the fall impact protection pants was excellent in the texture and elasticity of the outside and inside of the pants. There was no discomfort due to the pad(4.60), and no difficulty in movement during wearing activities was reported. During squatting, it was evaluated as 4.80, indicating that the motion adaptable hip joint and knee pads were highly effective during operation.

South Korea needs reorganization of dispute resolution system due to the frequent occurrence of a case that trade secret or technique are leaked. First, the distributed various laws are established and enforced by enacting and enforcing individual laws. Therefore, the redundancy problems, the collision of individual laws, the decline in diversity, integrity, and connectivity are issues. An independent legal system is needed by Act on the Prevention and Protection of Technology Leakage. Thereby, The support system of technological protection that is sprayed in government departments such as the Small and Medium Business Administration, the Ministry of Trade, Industry and Energy, the Patent Office, the Fair Trade Commission, the Trade Committee, the National Police Agency, and the Spy Agency integrates and unifies institutionally, and it is necessary to advance a policy with functional division. Second, the Patent Tribunal, the Invention Promotion Act, the Industrial Property Right Dispute Mediation Committee by the patent law, the Industrial Technical Dispute Mediation Committee on the Industrial Technology Outflow Prevention and Protection Law and the Medium and Small Firm Dispute Mediation and Arbitration Committee on Small Business Technology Protection Support Law are installed. However, since it established the integrated law on the Act on the Prevention and Protection of Technology Leakage, it is desirable to set the merged operation of establishment on the Technical Dispute Mediation Committee under the Small and Medium Business Administration or the Ministry of Trade, Industry and Energy.

Bacillus subtilis strains produce a broad spectrum of bioactive peptides. The lipopeptide surfactin belongs to one well-known class, which includes amphiphilic membrane-active biosurfactants and peptide antibiotics. Both the srfA promoter and the ComP-ComA signal transduction system are an important part of the factor that results in the production of surfactin. Bs-M49, obtained by means of low-energy ion implantation in wild-type Bs-916, produced significantly lower levels of surfactin, and had no obvious effects against R. solani. Occasionally, we found strain Bs-M49 decreased spore formation and the development of competence. Blast comparison of the sequences from Bs-916 and M49 indicate that there is no difference in the srfA operon promoter PsrfA, but there are differences in the coding sequence of the comA gene. These differences result in three missense mutations within the M49 ComA protein. RT-PCR analyses results showed that the expression levels of selected genes involved in competence and sporulation in both the wild-type Bs-916 and mutant M49 strains were significantly different. When we integrated the comA ORF into the chromosome of M49 at the amyE locus, M49 restored hemolytic activity and antifungal activity. Then, HPLC analyses results also showed the comA-complemented strain had a similar ability to produce surf actin with wild-type strain Bs-916. These data suggested that the mutation of three key amino acids in ComA greatly affected the biological activity of Bacillus subtilis. ComA protein 3D structure prediction and motif search prediction indicated that ComA has two obvious motifs common to response regulator proteins, which are the N-terminal response regulator receiver motif and the C-terminal helix-turn-helix motif. The three residues in the ComA N-terminal portion may be involved in phosphorylation activation mechanism. These structural prediction results implicate that three mutated residues in the ComA protein may play an important role in the formation of a salt-bridge to the phosphoryl group keeping active conformation to subsequent regulation of the expression of downstream genes.

As we enter the era of big data, the value of personal information is becoming ever more important. However, personal information protection laws in Korea have several issues. Furthermore, existing research are limited in their ability to facilitate a comprehensive understanding of measures to improve personal information protection laws. Accordingly, this study analyzes improvements to be made in the current personal information protection laws based on existing research. A total of 39 research articles discussing the problems of the personal information protection law were selected and analyzed by applying the meta - analysis technique. According to the results, the various issues such as the meaning and scope of personal information, the role and obligations of relevant parties, provision of personal information to third parties, and redundant and imbalanced regulations in special acts in each field. that exist in the current personal information protection laws were confirmed. This study contributes to the improvement of inconsistency between information protection laws and related special laws in each field in practice. Academically, it will contribute to understanding the problems of th law from the macro perspective and suggesting the integrated improvement ways of the law.

Water quality standards (WQS) are mandatory to guarantee the human health and protection of aquatic ecosystems, and maintain the condition of suitable water quality. The present WQS for the protection of human health in Korea contain nine substances (As, Cd, $Cr^{6+}$, CN, Pb, Hg, ABS, organophosphorus compounds and PCBs), but it is insufficient to preserve the human and aquatic ecosystem from a variety of chemicals. Therefore, it is necessary to expand the substance of WQS for the protection of human health. In this study, we chose the 20 chemicals from 43 chemicals of the project entitled 'Development of Integrated Methodology for Evaluation of Water Environment'. The methodology for calculating water quality criteria was amended from the US Environmental Protection Agency (US EPA)'s equation for deriving ambient water quality criteria for the protection of human health. The factors including fish intake, drinking water intake, and human body weight used in the equation reflected Korean situations. The monitoring values were derived from the water quality monitoring data in Korean four main rivers. The orders of priorities of chemicals were evaluated by human health risk assessment, and the proposed WQS was derived by technical and economic analyses. These results were reflected to expand the WQS for the protection of human health.

Currently security researchers focus on protection of program and data from malicious users and accidents. Therefore, many firewalls and intrusion detection systems have been developed commercially. The intrusion tolerance is a new concept that is the last line of defense for the information survivability. It emphasizes availability and integrity to provide critical system services continuously even when system is compromised. In this paper, we classify current intrusion tolerant technologies from the point of view of program and data. Furthermore, we propose an integrated framework that supports intrusion tolerance of program and data.

Although there are various factors that threaten the security of ships, one of the most harmful is corrosion. It is not easy to find corroding areas and the status of corrosion, even though corrosion causes serious problems such as submergence and marine pollution as a result of leaking oil and polluted water. To monitor the corrosion of ships, non-destructive inspection, weight loss coupons, electrical resistance, linear polarization resistance, zero resistance ammeter, and electrochemical impedance spectroscopy have been developed. However, these methods require much time to detect corrosion, and most are not appropriate for real time monitoring. Coating, sacrificial anode, and impressed current cathodic protection (ICCP) methods have been developed to control corrosion. The ICCP and sacrificial anode methods are the most popular ways to prevent ship corrosion. However, ICCP is only appropriate for the outside of a ship and cannot be used for complex structures such as ballast tanks because these are composed of many separate chambers. Sacrificial anodes have to be replaced periodically. This paper proposes an integrated corrosion monitoring and control system (ICMCS) that can detect corrosion in real time and is appropriate for complex structures such as ballast tanks. Because the system uses titanium for an anode, exhausted anodes do not need to be replaced.

Reliability in safety-critical systems and equipment is of vital importance, so the probabilistic safety assessment (PSA) has been widely used for many years in the nuclear industry to address reliability in a quantitative manner. As many nuclear power plants (NPPs) become digitalized, evaluating the reliability of safety-critical software has become an emerging issue. Due to a lack of available methods, in many conventional PSA models only hardware reliability is addressed with the assumption that software reliability is perfect or very high compared to hardware reliability. This study focused on developing a new method of safety-critical software reliability quantification, derived from hardware-software integrated environment testing. Since the complexity of hardware and software interaction makes the possible number of test cases for exhaustive testing well beyond a practically achievable range, an importance-oriented testing method that assures the most efficient test coverage was developed. Application to the test of an actual NPP reactor protection system demonstrated the applicability of the developed method and provided insight into complex software-based system reliability.

In this paper, we analyze the capability of satellite broadcasting systems to offer different levels of quality of service (QoS). We focus on the European telecommunications standards institute satellite digital radio and digital video broadcasting satellite handheld (DVB-SH) standards, which have recently been proposed for satellite broadcasting communications. We propose a strategy to provide different levels of QoS for the DVB-SH standard on the basis of an extension of the interleaving scheme, referred to as molded interleaver, which supports low latency service requirements for interactive services. An extensive analysis based on laboratory measurements shows the benefits of this solution. We also present a multilevel coding (MLC) scheme with multistage decoding designed for broadcasting communications as an alternative to the existing standards, where services with different levels of QoS are provided. We present a graphical method based on mutual information for the design and evaluation of MLC systems used for broadcasting communications. Extensive simulations for a typical satellite channel show the viability of the proposed MLC scheme. Finally, we introduce multidimensional constellations in the proposed MLC scheme in order to increase the number of different protection levels.

With the coming of information times, digital contents are widely applied in various fields of the society. Along with this, scholars provided many techniques and research approaches related to digital contents management and copyright protection. But till now, most proposed techniques and approaches are based on single system. The independency and separation among management systems causes the problems such as application across systems are limited, and resources sharing can't be available, etc. In this paper, for the application cross systems and contents sharing, we propose the cross-systems DRM approach based on unified metadata. This approach can be applied for the incorporation of multiple congeneric or heterogeneous CMSs, in the same time, solve the copyright problem cross digital content systems.
