In this paper, we review the domestic reliability standards and its global counterparts IEC/TC 56 international reliability standards. Recently private transfers of reliability certification control tower has established in Korea. Some check points to consider regarding the control tower transfer process to the non-government organization are suggested. Also the IEC/TC 56 and its relevant reliability standards are introduced. Understanding of the IEC/TC56 system will be helpful for the time of non-government organization control tower transfer in the reliability certificate specification

The purpose of this research was to develop an index for the certificate systems of family-friendly corporations. To be specific, first of all this research reviewed indexes which were developed in foreign countries. Second, it examined the domestic indexes related to the evaluation of family-friendly corporations. Third, it derived characteristics of family-friendly corporations through an in-depth interview with recruiters from those corporations in Korea and developed the index for the certificate systems of family-friendly corporations. And fourth, it tested the validity and reliability of the developed index. Based on the characteristics of family-friendly corporations which were revealed through the qualitative analysis on the data from the in-depth interview with recruiters from 30 family-friendly corporations, we developed 10 indexes for the certificate systems of family-friendly corporations. Also the analysis of the validity and reliability of the developed index indicated that it has high validity and reliability. Finally this research proposed how to apply this developed index to policies related to the certificate systems of family-friendly corporations.

Objectives : This study was done to evaluate the reliability of education and occupational class between using the health survey and the death certificate data. Methods : The 1998 National Health and Nutrition Examination Survey (NHANES) was conducted on a cross-sectional probability sample of South Korean households, and it contained unique 13-digit personal identification numbers that were linked to the data on mortality from the Korean National Statistical Office. The data from 263 deaths were used to estimate the agreement rates and the Kappa indices of the education and occupational class between using the NHANES data and the death certificate data. Results : The simple and weighted Kappa indices for education were 0.60 (95% CI=0.53-0.68) and 0.73 (95% CI=0.67-0.79) respectively, if the educational level was grouped into five categories: no-formal-education, elementary-school, middle-school, high-school and college or over. The overall agreement rate was 71.9% for these educational groups. The magnitude of reliability, as measured by the overall agreement rates and Kappa indices, tended to increase with a decrease in the educational class. The number of non-educated people with using the death certificate data was smaller than that with using the NHANES data. For the occupational class (manual workers, non-manual workers and others), the Kappa index was 0.40 (95% CI=0.30-0.51), which was relatively lower than that for the educational class. Compared with the NHANES, the number of non-manual workers for the deceased who were aged 30-64 tended to be increased (8 to 12) when using the death certificate data, whereas the number of manual workers tended to be decreased (59 to 41). Conclusions : The socioeconomic inequalities in the mortality rates that were based on the previous unlinked studies in South Korea were not due to a numerator/denominator bias. The mortality rates for the manual workers and the no-education groups might have been underestimated.

전자서명법 전면개정(2020. 12. 10, 시행)으로 시장에는 다양한 인증서가 출시되어 경쟁하고 있다. 치열한 경쟁하에서 대형 IT플랫폼 업체의 인증서 시장 점유율이 높아지고 있으며 결국에는 시장을 독식할 것으로 예측되기도 한다. 이에 소비자의 인증서 선택요인을 파악하고, 선택요인들 간에 중요도 차이는 어떠한지를 파악하는 것은 기업의 인증서 시장에 대한 전략 수립 및 제품 포지션이닝에 필수 요소이며, 정부의 인증서 정책 방향설정에 키포인트라 하겠다. 본 연구에서는 선행 논문 및 설문조사 등의 내역을 기반으로 소비자의 인증서 선택요인을 추출하였고, 추출된 선택요인을 기반으로 델파이조사를 통하여 4가지 선택요인(발급기관의 신뢰성, 프로그램 설치, 인증서 사용방법, 범용성(사용처))을 선별하였다. 선별된 선택요인으로 소비자 설문조사를 실시하여 컨조인트 분석결과, 발급기관의 신뢰성이 가장 중요한 효용가치로 나타났다. 다음 순으로 인증서 사용방법, 프로그램 설치, 범용성(사용처) 순으로 중요도가 나타났다.

우리나라는 2004년 자유무역협정(FTA, Free Trade Agreement) 발효를 시작으로 세계에서 가장 활발하게 FTA에 참여하고 있는 국가이다. FTA 제도를 활용하기 위해서는 협정별 원산지 결정기준의 충족, 직접운송 원칙 등 여러 요건을 반드시 충족하여야 한다. 우리나라 관세청의 수입검증 관련 해외 수출자는 제공한 원산지 증명의 검증 의무가 있다. 그러나 만약 검증 실패시, 수입국에서 과세가 이루어짐에 따라 특혜관세 혜택을 받았던 우리나라 수입자에게 관세채무가 발생하게 된다. 따라서 위험부담을 덜기위해 원산지 검증 이전에 원산지 증명 신뢰성에 영향을 미칠 수 있는 변수를 확인하는 것이 중요하다. 본 연구의 실증분석 결과에 의하면 수출기업의 특성 중 무역경험과 담당자 전문성이 발급된 원산지 증명 신뢰성과 밀접한 관련성이 있다. 수출국가 특성 중 FTA 참여수준이 원산지 증명 신뢰성에 긍정적으로 영향을 미치고 있는 것이 확인되었다.

This study promotes the understanding of landscape technicians by, assessing the professional qualification system that aligns with the needs of the 21st-century environment, distinct from the industrialization era, It, provides basic theoretical insights into the multi-dimensional connections between the motivation for a certificate and the career decision-making self-efficacy of individuals with a demand for the certificate in the structural aspect. The collected data underwent a comprehensive analysis involving frequency assessments, confirmatory factor analysis, descriptive statistics, reliability tests, and correlation analyses. The study found differences according to particpants' diverse sociodemographic characteristics including gender, place of residence, educational background, and occupation. The motivation for obtaining a certificate had significant positive effects on their career-decision-making self-efficacy, within the context of structural relations. The study findings on the relations between motivation for obtaining a certificate and career decision-making self-efficacy demonstrate that the direction and intensity of efforts to obtain a certificate can increase the career decision-making self-efficacy of people hoping to become landscape technicians.

A Certificate Revocation List(CRL) should be distributed quickly to all the vehicles for vehicular communications to protect them from malicious users and malfunctioning equipment as well as to increase the overall security and safety of vehicular networks. Thus, a major challenge in vehicular networks is how to efficiently distribute CRLs. This paper proposes a Multimedia Object Transfer(MOT) protocol based on CRL distribution scheme over T-DMB infrastructure. To complete the proposed scheme, a handoff method, CRL encoding rules based on the MOT protocol, and relative comparison are presented. The scheme can broaden breadth of network coverage and can get real-time delivery with enhanced transmission reliability. Even if road side units are sparsely deployed or, even not deployed, vehicles can obtain recent CRLs from T-DMB infrastructure effectively.

In this paper, we propose the AI certification standardization activities for systematic research and planning for the standardization of trustworthy artificial intelligence (AI). The activities will be in two-fold. In the stage 1, we investigate the scope and possibility of standardization through AI reliability technology research targeting international standards organizations. And we establish the AI reliability technology standard and AI reliability verification for the feasibility of the AI reliability technology/certification standards. In the stage 2, based on the standard technical specifications established in the previous stage, we establish AI reliability certification program for verification of products, systems and services. Along with the establishment of the AI reliability certification system, a global InterOp (Interoperability test) event, an AI reliability certification international standard meetings and seminars are to be held for the spread of AI reliability certification. Finally, TAIPP (Trustworthy AI Partnership Project) will be established through the participation of relevant standards organizations and industries to overall maintain and develop standards and certification programs to ensure the governance of AI reliability certification standards.
