New occupational qualification system built on NCS(National Competency Standard) aimed to induce industries, the final appliers of qualification, to play a leading role in designing qualification and to spontaneously apply such qualification standard to employment and promotion so as to reinforce universality of qualification. In this study, we verified the validity of NCS level of qualification categories for 130 occupational fields by redesigning NCS-based new occupational qualification system with a focus on 7 major areas, including mechanical field, which were found to have wide-ranging social ripple effect throughout society and high acceptability in 2014. The results of study on suitability at qualification level suggested the followings: First, there is a difference in number of competency units for each qualification category, depending on area. New qualification covering 7 major areas included 15.3 competency units for each qualification category, which exceeds the number of competency units(about 10 units) in subdivided NCS. By field, some difference was found with 7.9 competency units for cultural field and 22.6 competency units for information and communication area. Second, preference above normal level was observed in the criteria, procedure and method for determining qualification redesigning. However, preference below normal level was exhibited in connection with possibility of linkage with overseas qualifications, although preference was above normal level in relation to the suitability of design/qualification level and qualification categories based on lifelong career development path within scope of NCS as the criteria for determining the redesign of qualification categories. Second, we compared NCS level and SC(Sector Council level, and the results showed that NCS level was found to be somewhat well-defined. For the qualifications with different definitions, it was deemed difficult to determine superiority between NCS level and SC level. However, majority opinion indicated that it would be desirable to follow NCS level because NCS was created through collection of opinions for a prolonged period.

Internal replaceable electronic module substitutions can impact EMC (ElectroMagnetic Compatibility) qualification testing and results if EMC testing is conducted at the cabinet level. The impact of component substitutions on EMC qualification results therefore should be evaluated. If a qualitative evaluation is not adequate to ensure that the modified product will not impact the cabinet level EMC qualification results, a new qualification testing should be conducted. Component level retesting should be conducted under electromagnetically equivalent conditions with the cabinet level test. This paper analyzes the propagation of conducted susceptibility test waveforms in a representative cabinet and evaluates the impact of component substitutions on cabinet level EMC qualification results according to the location of the replacement items. A guideline for a qualitative evaluation of the impact of component substitutions is described based on the propagation of the conducted susceptibility test waveforms. A module level test method is also described based on an analysis of the shielding effectiveness of the cabinet.

The equipment composed of many complicated electronic stuffs undergoes diverse stresses caused by mechanical vibrations during its service. Thus, to ensure its proper operation in the field a simulated vibration test has to be carried out in the laboratory with the Vibration Qualification Level, the test specification, which can include the real environment. In this paper we intent to deal with method and procedure for determining the Vibration Qualification Level so as to estimate the vibration-endurance for the equipment precisely.

대규모 사이버공격이나 테러가 발생하여 국가가 막대한 피해를 보거나 안보에 치명적인 위협이 되었을 때에서야 비로소 사이버보안 인력 양성에 대한 사회적 관심은 높아진다. 또한, 정부에서는 사이버보안 인력 양성과 확보 정책을 제시하곤 한다. 하지만, 양성된 사이버보안 인력이 관련 기관이나 기업에 취업한 이후에 이들을 체계적으로 관리할 수 있는 시스템은 아직 미약하다. 소프트웨어 인력은 표준화된 자격등급 모델이 있어서 각 등급별로 적합한 직무를 설정하여 관리하고 있다. 사이버보안 인력도 경력, 학력, 교육훈련 실적 등을 고려한 특화된 자격등급 모델이 필요하다. 자격등급을 부여함으로써 각 등급별로 수행할 수 있는 직무를 설정하고 부서의 직책과 직위도 등급을 고려하여 부여해야 한다. 따라서 본 논문에서는 사이버보안 인력의 효율적으로 관리하기 위한 자격등급 모델을 제안한다.

In the fields of reliability application, the most commonly used test methods for reliability qualification are zero-failure acceptance tests since they require fewer test samples and less test time compared to other test methods that guarantee the same reliability with a given confidence level. Usually values of shape parameters are assumed to be known in designing reliability qualification tests for Weibull lifetime distribution. It is important to select correct values of shape parameters to guarantee the specified reliability with given confidence level exactly. The effect of using wrong values of shape parameters in designing reliability qualification test for products with Weibull lifetime distribution is examined and selecting proper values of shape parameters for conservative reliability qualification is discussed.

This study is to identified the motivation level which university librarians in Korea perceived as motivating them, and to examine relationship between those motivation level and the demographic characteristics of university librarians. The results of this study are summarized as follows : (1) The factors that the motivation level is higher than the average (3.000) are shown to be human relation (3.399), working itself (3.198), and supervision (3.050), but the other factors : recognition (2.995), communication (2.985), salary (2.892), job evaluation (2.622), job environment (2.619), and promotion (2.126) are shown to be lower than the average. (2) In the results of X$^{2}$ test about the differences of the motivation level among 6 demographic attributes of the population, the attributes shown a significant difference are as follows : Salary : rank ; working terms ; sex ; national university or private one ; qualification. Promotion : rank ; sex ; national university or private one ; qualification. Recognition : rank. Human relation : no significant differences among 6 attributes. Work itself : rank ; sex. Communication : rank ; working terms ; sex ; education background ; qualification. Job evaluation : sex ; education background ; qualification. Job environment : sex ; national university or private one. Supervision : rank ; working terms ; sex ; education background ; qualification.

A design of reliability qualification test based on performance distribution is developed. In general, the performance of an item degrades as the time goes by and the failure of an item occurs when the performance degradation reaches the pre-determined critical level. This article considers the reliability qualification test based on a more tightened critical value at the earlier stage to reduce the evaluation testing time and cost. A numerical example is provided to illustrate how to use the developed reliability qualification test.

Nowadays, our industries and occupation are increased under the economy development of government. So, this paper introduce to compare with coefficient's of correlation on the time series of the education and the qualification in our country. For this reason, the decision making to qualifications' foresight which will be change to the education category-prospective on the time series. The qualification has claasified 5 degrees-master craftsman, professional engineer, engineer, technician(or industrial engineer), craftsman - and 516 qualification items. Education has classified to 4 degrees(7 degrees) - elementary, middle, high, high scholastic level school(college, university, graduation). This paper has matched to educational classification and qualification classification through the following method. We defined the same level between education and qualification after analysed correlation under the time series, so the craftsman equals high school graduation people, technician equals college graduation people, engineer quals university graduation people, now we could not analyse master and professional levels. This paper will suggest to the qualification's future policy direction and improve the education policy direction.
