본 연구는 주로 지각된 과잉자격의 부정적인 영향에 초점을 둔 기존연구의 관점에서 벗어나 지각된 과잉자격이 창의적 행동에 미치는 긍정적인 영향에 대해 분석하였다. 중국에서 금융업에 종사하는 종업원 282명을 대상으로 설문조사하여 구조방정식모형분석을 활용하였다. 분석결과, 지각된 과잉자격은 종업원의 창의적 행동에 긍정적인 영향을 미치는 것으로 나타났으며, 지각된 과잉자격과 창의적 행동 간의 관계에서 감정소진과 잡 크래프팅은 매개효과가 있는 것으로 나타났다. 본 연구는 지각된 과잉자격이 창의적 행동에 긍정적인 영향을 가져온다는 것은 지각된 과잉자격의 영향효과에 대한 연구를 어느 정도 풍부하게 하였으며, 창의적 행동, 감정소진, 잡 크래프팅, 조직지원인식의 관계를 실증함으로써 이론적, 실무적 시사점을 제공하였다. 과잉자격 인식에 대한 논의는 주로 종업원 개인 수준에 머물러 있으며 향후연구는 팀 수준 또는 조직 수준으로 확대해서 연구할 필요성이 있다.

자격의 현장성, 통용성에 미치는 요인을 알아보고자 자격의 기능에 대한 직무능력, 직무적합성과의 어떠한 관계가 형성되는지에 대한 모형을 제시하여 이들의 관계를 실증적으로 밝히기 위한 연구를 실시하였으며, 그 결과를 바탕으로 자격의 현장성, 통용성에 대한 실마리를 찾고자 하였다. 첫째. 기계분야 국가기술자격취득자의 경우 자격의 기능별(신호, 선도, 선별) 직무능력과 직무적합성과의 유의한 상관관계가 있는 것으로 나타났다. 둘째, 기계분야 국가 기술자격 취득자의 직무능력, 직무적합성에 가장 영향을 미치는 하위 요인은 신호기능이라는 것을 밝혀냈다. 셋째, 자격의 기능이 직무적합성에 미치는 영향에 대한 직무능력의 매개효과를 자격이 기능별로 밝혀낸 점이다. 선도 기능의 경우 매개효과가 없었으나 신호기능 및 선별기능이 매개효과가 있는 것으로 나타났으며 특히 신호기능이 상대적으로 가장 크게 영향을 미치고 있는 것을 밝혀냈다. 마지막으로 자격의 기능별 하위 요인에 대한 직무능력과 직무적합성과의 관계에 대한 연구모형을 제시하였다.

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.

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.

Since the late 1990's, FAA, NASA and the aerospace industry have worked together to develop the sharing system of the composite material qualification databases which were obtained through the standardized fabrication and testing procedures. The result was what is now known as the AGATE(Advanced General Aviation Transport Experiments) or NCAMP(National Center for Advanced Materials Performance) methodology, a more cost-effective concept that shifts the major responsibility for qualification and testing from the aircraft manufacturer to the material supplier. The properties of composite materials are largely dependent on the testing as well as the raw material properties and the manufacturing process including the process control parameters. Thus it is important in the composite material qualification to comply with the standardized testing procedures. In this paper, I will describe the standardized witness methodologies of certification engineers to reduce the effect of testing variability within the qualification data.

This study suggests a solution of an incentive system from the viewpoint of the external effect on the renting of firefighting qualifications and on rental agencies. Currently, the Human Resources Development Service of Korea does not have a penalty for neglecting to perform a search into qualification lending and rental agencies. In the short term, the penal clause should be strengthened so that companies and qualification holders cannot borrow or lend their qualifications. In addition, the Human Resources Development Service of Korea will increase the number of personnel dedicated to investigating the loaning of qualifications. It is necessary for the government to establish a penalty for neglecting to investigate the lending of qualifications for the Human Resources Development Service of Korea. In the long term, the state needs to make only minimal regulations. Also, the state needs to make companies and qualification holders feel like they benefit more when they are not borrowing or lending qualifications. The anticipated effect of this study is that the government will intervene appropriately by applying firefighting qualifications according to market principles. It can also be used as a basis for the revision of related laws on the renting of national technical qualification certificates and the investigation of rental agencies.

In this paper, we analyzed the revised guidance on electromagnetic (EM) interference qualification of Regulatory Guide 1.180 (Revision 2), which is published by the U.S. Nuclear Regulatory Commission for electromagnetic compatibility qualification for nuclear safety, by comparing it with that of the previous version. We confirmed that the test methods and the acceptance criteria of both CE101 and CE102 tests for conductive emission and RE102 test for radiating emission are changed in the recently revised Regulatory Guide 1.180 (Revision 2). Furthermore, we found that the revised Regulatory Guide 1.180 provides flexibility in the use of alternative methods for EM interference (EMI) qualification, in that a mix of the various base-standards is technically allowed. In addition, the primary revision of the updated Regulatory. Guide 1.180 is that MIL-STD-461G is to be adopted as the latest base-standard, instead of MIL-STD-461E. To evaluate the influence on EMI qualification for nuclear safety due to the endorsement of MIL-STD-461G, we thoroughly analyzed the modifications in the acceptance criteria and test methods for EMI qualification, and then validated the analyzed effect on the EMI qualification, which is caused by the revision of MIL-STD-461, by performing electromagnetic simulation for equipment under RE102 test.

The valve assembly used in nuclear power plants is important safety-related equipment. In the new standard, the physical attributes are measured using a valve diagnosis test, which is used in the expansion to other non-tested valves using a quantitative test-basis methodology. With a motor-operated actuator, the state of stem's lubrication is related to physical attributes such as the stem factor and the friction coefficient. This study analyzed the numerical transient of fluid and solid lubrication with a squeeze film effect due to the loading rate on the stem and the stem nut using the experimental data. The differential equation that governs the motion mechanism of the stem and stem nut is established and analyzed. The flow rate, the fluid and the solid contact forces are calculated with the friction coefficient. Finally, we found that a change in the friction coefficient results from a change of the shear force in the solid contact mode during the interchange process between the solid contact mode and the fluid contact mode. The qualitative understanding of the squeeze film effect is expanded quantitatively for forces, thread surface distance, velocity, and acceleration, with consideration of the metal solid contact and fluid contact.
