Rheumatoid arthritis (RA) is a chronic inflammatory disease, which is mainly characterized by disease of joints affected with synovial hyperplasia, pathological immune response, and progressive destruction; all of which represent an important social health problem. These provide new insights in its pathogenesis of rheumatoid arthritis diagnosis and disease progression in molecular changes. This review focuses on new serological and immunological markers which seem to be useful in early diagnosis and prognosis of rheumatoid arthritis. Therefore, such tests are widely conducted for serological biomarkers and the developments with such immunological factors to identify patients who are at risk for disease progression. This evidence of the disease based on laboratory medicine could provide the best outcome for patients. Finally, data from recent studies will help to refine the ultimate usefulness of this novel approach for early diagnosis, treatment, and helping clinicians to optimize therapy by using this approach.

Purpose: It can deduce improvement plan that recognizes any risk factors in initial production and mass production by using FMEA and through this process, the appropriate criteria for defence items can be established. Methods: It proposes two methodology - Apply DT/OT data achieved from the beginning mass production stage based on FMECA data of the design stage, to risk management, and risk management plan that reflected line and field faliure data in case of is offered. Results: It proposes the risk management plan through Bayesian method and the risk identification that considered MTTF estimated value in case of initial production process. In case of mass production process, both risk identification by using fault occurrence frequency scores and Byaesian method, In case of the Initial production and mass production, it proposes use both two methods. Conclusion: A more realistic risk identification method can be applied, and by this method the quality improvement effect is expected.

In the future, 5G technology will become the core infrastructure driving the 4th industrial era. For intelligent super-convergence service, it will be necessary to collect various personal information such as location data. If a person's high-precision location information is exposed by a malicious person, it can be a serious privacy risk. In the past, various approaches have been researched through encryption and obfuscation to protect location information privacy. In this paper, we proposed a new technique that enables statistical query and data analysis without exposing location information. The proposed method does not allow the original to be re-identified through polynomial-based transform processing. In addition, since the quality of the original data is not compromised, the usability of positioning big data can be maximized.

This study examines the technologies and application processes related to the use of pseudonym data of companies after the passage of the Data 3 Act to activate the data economy in earnest, and what companies should prepare to use pseudonym data and what will happen in the process It was intended to contribute to the elimination of uncertainty. In the future, companies will need to extend the information security management system from the perspective of the existing IT system to manage and control data privacy protection and management from a third party provisioning perspective. In addition, proper pseudonym data use control should be implemented even in the data use environment utilized by internal users. The economic effect of market change and heterogeneous data combination due to the use of pseudonymized data will be very large, and standards for appropriate non-identification measures and risk assessment criteria for data utilization and transaction activation should be prepared in a short time.

In this paper, the technology and capabilities required for the job of developing security software recommended by the Cybersecurity Human Resources Development Framework of the National Initiative for Cybersecurity Education (NICE) were studied. In this paper, we describe what security skills are needed for the task of developing security software and what security capabilities should be held. The focus of this paper is to analyze the consistency between security technologies (core and specialized technologies) required for security software development tasks and the curriculum of information protection-related departments located in Seoul, Korea. The reason for this analysis is to see how the curriculum at five universities in Seoul is suitable for performing security software development tasks. In conclusion, if the five relevant departments studied are to intensively train developers of development tasks for security software, they are commonly required to train security testing and software debugging, how secure software is developed, risk management, privacy and information assurance.

Traditionally research in Service Oriented Architecture(SOA) security has focused primarily on exploiting standards and solutions separately. There exists no unified methodology for SOA security to manage risks at the enterprise level. It needs to analyze preliminarily security threats and to manage enterprise risks by identifying vulnerabilities of SOA. In this paper, we propose a metric-based vulnerability assessment method using dynamic properties of services in SOA. The method is to assess vulnerability at the architecture level as well as the service level by measuring run-time dependency between services. The run-time dependency between services is an important characteristic to understand which services are affected by a vulnerable service. All services which directly or indirectly depend on the vulnerable service are exposed to the risk. Thus run-time dependency is a good indicator of vulnerability of SOA.

Because the networks and systems become more complex, the implementation of the security countermeasures for important Information Systems becomes more critical consideration. The designers and developers of the security policy should recognize the importance of building security countermeasures by using both technical and non-technical methods, such as personnel and operational facts. Security countermeasures may be made for formulating an effective overall security solution to address threats at all layers of the information infrastructure. But all these works can be done after assuming who is the threat agent. In this paper we identify the treat agents for information systems, summarize the characteristics of threat agents, and apply weighting factors to them.

It is very important to track whether software is properly developed according to requirements. This study suggests a method to track requirements by using a tracking table. In this study, the tracking table indicates why such requirements are included by detailing the content of requests for proposals and proposals. The table also facilitates verification of the consistency between outputs and the integrity by having ID codes of each requirement mapped to each output. Furthermore, as this study was conducted, it was found that some factors were required to be added or supplemented to the outputs at the requirement gathering stage of MaRMI-Ⅲ v.4.0 methodology. Thus, this study seeks to present this additional result along with the enhanced tracking table. By verifying outputs, the tracking table presented in this study will help to reduce all kinds of risks and problems that may occur in software development due to the lack of management of requirements. In addition, the output of the requirement-gathering stage of MaRMI-Ⅲ v.4.0 methodology will be improved/supplemented according to the creation of tracking tables; this will increment the applicability of the MaRMI-III methodology.
