Electrical product safety certification is for public safety. Korea electrical safety certification (KC) is being tested and certified on the base of Korean electrical appliance safety act and KC scheme. There are operating system and Electrical safety standards in the KC scheme. KC' operating system was adapted from japan operating system of Japan certification scheme. But KC certification' electrical safety standard was adapted from IEC standards of IECEE CB scheme. So There are many problems such as difference of version between KC standards and IEC standards, discrepancy between operating system and standards. Therefore, This paper analyzed the reason of discrepancy and proposed the improved KC certification operating system in order to reduce cost and to save time in the procedure of issuing KC approval for public safety in using electrical products and also for global competence.

As the cloud computing law was passed in March, 2015, many private companies and public organizations give consideration to introduce cloud computing services. However, most of them are still concerned about the security issues in cloud computing services. To solve the problem, a certification system of cloud security is necessary as an enabler for adoption of the trusted cloud services. There have been a number of studies about certification systems for cloud security, but only few studies exist about certification scheme of cloud security. Therefore, in this study, foreign certification systems for cloud security are analyzed to draw requirements for developing a domestic certification scheme for cloud security. Based on the result of analysis, this study proposes the three certification schemes of cloud security, which have been reviewed by the focus group interview method to draw advantages and disadvantages of each scheme.

Crystalline silicon photovoltaic module certification began in 2007. "Renewable Energy Equipment Certification Scheme" was implemented until July 28, 2015. Then, the scheme was changed to "KS Certification Scheme" since July 29, 2015. A total of 2,331 models have been certified by 2016. The proportion of multi crystalline modules in certified products is higher than that of mono crystalline modules, and Korean modules account for 78% of the total certification modules. Chinese solar cells account for the highest percentage of 40% of the total modules and 62.4% of modules certified in 2016 use Chinese solar cells. With the development of technology, module power is continuously increasing, and efficiency is also rising. The average efficiency of mono crystalline module is 0.74% higher than the average of multi crystalline module. As a result of comparing domestic module with Chinese module, the highest efficiency of mono crystalline module and multi crystalline module and the average efficiency of mono crystalline module are higher than those of Chinese module, but the average efficiency of multi crystalline module is similar to that of Chinese module.

Total shipping accounts for 2.9 % of the annual average percentage of global anthropogenic GHG emissions. The International Maritime Organization implements EEDI (Energy Efficiency Design Index), Energy Efficiency eXisting-ship Index (EEXI), and Carbon Intensity Indicator (CII) as regulatory frameworks for shipping decarbonization. The Republic of Korea has enforced the Act on Development and Popularization of Greenship from 2020 and publicly announced the 1st national plan which was named 『2030 Greenship-K Promotion Strategy』 for the activation of a greenship market. The Greenship Certification Scheme is going on for the sustainability of Korean shipbuilding and shipping industries, to secure clean maritime environments, as well as to contribute to the national economy. Greenship Certification guarantees the credit of such eco-friendly technologies and products for shipping. The certification is going to be the basis of industrial competitiveness in coastal and international shipping. This study investigates an existing certification process, identifies the limitations, and proposes the process improved with several case studies. The improved certification scheme may have rationality for Net-zero with regard to climate alignment.

User authentication is an important requirement to provide secure network service. Therefore, many authentication schemes have been proposed to provide secure authentication, such as key agreement and anonymity. However, authority of scheme is limited to one's self. It is inefficient when authenticated users grant a certification to other users who are in an organization which has a hierarchical structure, such as a company or school. In this paper, we propose the first authentication scheme to use Attributes-Based Re-encryption that creates a certification to other users with specified attributes. The scheme, which has expanded from Rhee et al. scheme, has optimized computation performance on a smart card, ensuring the user's anonymity and key agreement between users and server.

In the last decade many advanced home network services have been provided by construction industry, and many researches on the area have been carried out. One of the problems we are confronted with is that we do not have a standard classification scheme for home network services yet. In this paper a more stable classification scheme is suggested after comparative analysis of many different schemes in previous researches. More commonly highly attended service categories in the scheme is selected, and those are examined in terms of how commonly they are supplied by construction industry. In the later part of this paper the current home network building certification code is reviewed if the code complies with the highly attended categories in the classification scheme suggested in this paper. Some ideas to improve the current certification code is suggested by adding or optionally adding the highly attended categories.

Currently, the Korean railway safety law (RSL) and its ordinances have been enforced for the guarantee of the safety of railway. In RSL, the quality certification is required to guarantee the safety and performance of railway components or systems. However, not much attention has been focused on the quality certification scheme for railway components or systems since the scheme is relatively new. Therefore, in this investigation, the detailed guidelines and main contents for the enforcement of quality certification for railway components will be suggested, and the detailed items including the procedures, subjects, management, etc., will be addressed. Moreover, a better understanding on quality certification for railway components will be provided.

Seo et al. criticizes that Hu-Niu-Yang's certification scheme is not enough to satisfy the security requirements of a smart card-based certification scheme because it has a weakness of password guessing attack as well as gives attackers opportunities to be disguised as legitimate users. However, Seo et al. also has a weakness not satisfying the security requirements. This paper suggests a new scheme that contains the characteristics of certification scheme provided by Seo et al. but compensates weak points. The findings show that the new scheme is more safety and efficient than Seo et al.'s

The purpose of this study is to analyze the data repository certification scheme and to propose a strategy to promote Coretrustseal certification. The certification system to be analyzed includes Coretrustseal, RatSWD, CLARIN certificate B, DIN 31644, ISO 16363, TDR and nestor. Among them, Coretrustseal certification is a core certification system that meets the standards and requirements of other certifications. Therefore, in this study, the Coretrustseal certification promotion strategy was proposed step by step. The proposed certification promotion strategy includes a list of research data policies and guidelines and examples of certification applications for use by institutions that operate domestic data repositories. Through this CTS certification process, each institution can secure research data policies and guidelines, and when CTS certification is obtained, it is judged that international reliability of the data repository can be secured.
