This study was conducted to examine the remuneration curriculum of vocational ability development training teachers and instructors and to examine ways to apply micro credentials. To this end, the current status of the remuneration curriculum of vocational ability development training instructors and instructors at K University's Competency Education Development Institute, the characteristics of micro credentials, and the possibility of linking the remuneration curriculum to micro credentials are as follows. First, most of the recognition of digital certificates was positive for digital certificates such as digital credit, digital badge issuance, and recognition of the recognized qualification process of maintenance education when completing the training course. In addition, as a method of applying micro credentials to conservative education, various cases were proposed to benefit from conservative education, systematization and grading of the qualification process, and credit of the qualification process. Second, as an institutional supplement to enhance the utilization of conservative education using micro credentials, the need to expand NCS-based major conservative education, provide efficient learning contents and learning methods, and set minimum completion time. In addition, the most common response as a way to improve the understanding of teachers and instructors in vocational ability development training was the micro credential promotion plan. Third, in the role of conservative education institutions and vocational ability development training instructors and instructors, conservative education institutions mention maintaining educational quality the most, and active participation was the role of vocational ability development training instructors. Through this study, it is expected to establish a vocational training environment that can enhance expertise and provide a practical portfolio of practical competency history by linking the remuneration curriculum of vocational competency development training instructors and micro credentials.

Software Maintenance needs to continually improve from corrective maintenance to operational management and service improvement. In this study, we propose a software maintenance maturity model and its evaluation criteria based on 4 maintenance projects of K organization. For the proposal, we derive 13 process areas and 64 evaluation criteria based on some references such as SMMM, ITSMM, ITIL. We evaluate the criteria using 5-point scale, and then establish the maturity model of K organization classified by levels of the maturity model based on the evaluation result. And, to verify and improve the maturity model of K organization, we propose improvements for evaluation criteria. In addition, we apply the maturity model to the 4 projects, evaluate the projects, and propose improvements for the projects based on the evaluation result to identify how the model shows software maintenance improvement.

본 논문의 목적은 중소기업 정보화 물결로 도입된 ERP 사용 중 당면하게 되는 유지보수 요청에 대한 효율적 지원체계를 ERP공급 기업 입장에서 마련하여 ERP 사용효과를 극대화 하고자 하는 것이다. 이러한 목적 달성을 위하여 본 연구에서는 국내 ERP 공급기업 사례를 중심으로 지원체계의 합리적 기준안을 사례로 참조하였다. 그리고 기업의 전통적이고도 관행적인 그동안의 비즈니스 프로세스와 ERP에서 제시하는 비즈니스 프로세스와의 업무적 차이를 유지보수 지원이라는 과정을 통하여 중소기업의 업무혁신이 자연스럽게 흡수되도록 하였다. 효율적 지원체계 연구 과정 중 누락되거나 미흡한 부분이 일부 있었으나 ERP 공급기업과 ERP 도입 기업이 당면한 우선적인 과제라 생각되어 현재의 사후지원 방안보다 신속한 유지보수관리가 적용되는 방안을 연구하였다. 이 개선 방안은 다음의 두 가지로 요약된다. 첫째, 유지보수 지원절차를 개선하여 ERP 도입기업의 지원요청이 ERP공급 기업의 지식 DB로 구축되도록 하는 것이다. 둘째, 지원요청 발생 가능한 사항을 ERP 도입 기업에게 사전 제공함으로써 자체 장애해결 능력을 부여하여 ERP 사용효율을 향상시키도록 하는 것이다. 본 논문은 ERP의 효율적 유지보수 지원체계를 정리한 것으로서 연구과정 중 나타난 문제점 들을 점차 개선하고 사후관리관련 구성원들이 보다 전문성을 갖추어서 문제처리에 대한 일관성과 신속성을 갖추게 된다면 ERP 도입기업의 ERP 사용효율을 높여주어 정보화를 통한 기업경쟁력이 더욱 강화될 수 있을 것이다.

As the "Partial Amendment to the Vocational Competency Development Act" was passed, and the mandatory refresher training was legislated in March 2020, HRD education institutions has prepared a plan for the improved refresher training to strengthen the competency of vocational training teachers and to improve the quality of refresher training. However, as demand for refresher training is concentrated in partial occupations, it is necessary prepare a separate plan to recognize personal learning as a refresher training for a minority of teachers who are not provided with a training. Therefore, this study aims to identify areas of a minor training occupations that don't exist many participants for a refresher training and to derive ways to recognize their multiple education experiences and participations instead of attending a refresher training. To this end, literature review, analysis of current situation, consultation with stakeholders, and written interviews with experts were conducted. As a result, a minority of training occupations was defined as type 1 and type 2 and ways of the recognition of refresher training for minority of training occupations which embrace various educational types were derived. Lastly, discussions and suggestions on the expansion of the scope of the recognition of refresher training for minority of training occupations were provided.

Objective: The purpose of this study is to identify the strengths and problems of the current in-service education system, and suggest ways to improve it in the future by looking at the current status of in-service education to strengthen the expertise of teachers and directors of childcare centers. In particular, I would like to search the current status of in-service education, including on-line special job competency education, which is responsible for one of the pillars of in-service education, and present the problems and measures to improve them. Methods: To that end, the present study conducted an analysis of issues based on the previous research on in-service education of childcare teachers' education, and conducted a literature examination focusing on laws, policies, and foreign cases related to in-service education. Results: In-service education for childcare teachers was categorized into educational process diversification and professionalism, educational method diversification, qualification management, and educational support, which were again organized into 14 core tasks. In addition, as a recent phenomenon that has not been discussed in detail in the preceding study, the phenomenon of increased participation in on-line special job competency education at the site of in-service education was analyzed and the problems were presented. Conclusion/Implications: Based on the results of this study, I proposed development measures such as changing the term 'in-service education' and recognizing the diversity of job competency education, the credit rating banking system for job competency education, the provision of on-line job competency education curriculum (basic courses/enhancing courses) for collective education courses, the expansion of education support for promotion to a higher grade courses and the conversion of the mandatory evaluation system for in-service educational institutions.

Cost of capital is one of the key factors of accounting regulation policy for telecommunication market. This paper aims at investigating efficient policy improvements concerning accounting regulation for telecommunication market focused on cost of capital calculation methods and its application. At First, cost of capital estimating method should be improved. In estimating the cost of equity capital, it is necessary to use benchmark method for Equity risk premium. It will reduce analytical errors caused by a rapid economic change and inflation. It is also more desirable to use debt premium adding method for the cost of debt capital. Optimal capital structure method may be considered a better way to estimates capital structure. Secondly, cost of capital estimating process also has to be reformed. Telecommunication industry changes rapidly so it does not reflect fast environmental changes. Therefore, cost of capital should be calculated every year. Cost of capital should be calculated by individual companies. There is information asymmetry between regulators and regulatees. Because of that cost of capital calculating process takes long time and cost a lot. To solve this problem, regulator should legislate on cost of capital calculation and then regulating companies report the calculating result. Lastly, major telecommunication companies are all listed now and it is possible to calculating it separately. We must continuously improve the estimating method and application of cost of capital and due to the fast growing of telecommunication industry. The process of determining the calculating method must be discussed and best method chosen.
