최근의 소프트웨어 개발은 객체지향 프로그램 개발 기법을 사용하여 소프트웨어를 개발하고 있다. 초보 개발자에게는 적절한 객체를 식별하고 정확한 속성과 행위를 부여하는 객체 지향 기법은 상당히 힘든 문제이다. 객체의 집합, 즉 클래스 모델링 기법에도 재사용 기법을 사용한다면 이미 작성된 모델을 참조하여 객체 지향 개발 기법을 처음 접하는 초보 개발자에게는 학습의 기회를 제공하고, 숙련된 개발자에게는 검증된 모델을 통해 모델링 실패를 방지할 수 있는 안전성을 제공할 수 있다. 본 논문에서는 유사성(Similarity) 측정 기법을 적용하여 클래스간의 유사도를 판단하고, 관계 일치여부를 분석하여, 재사용 가능한 클래스를 검색하는 모델을 제안한다.

선박화재는 육상과 달리 숙련된 인원과 다양한 장비에 의한 소화활동이 곤란하며 거의 자체적인 진화작업을 수행해야하므로 소화가 쉽지 않다. 화재는 일반적으로 화염에 의한 인명사고 보다 매연에 의한 질식사의 확률이 높으므로 인명사고를 방지하기 위해서는 신속한 초기 진화가 가장 중요하다. 하지만 여러 가지 이유로 부득이 소화가 지연되거나 불가능할 경우에는 화재 구역으로부터 신속한 탈출만이 인명사고를 방지할 수 있다. 이 연구에서는 CFD기법을 이용한 시뮬레이션을 통하여 선박화재시 탈출에 지장이 되는 매연농도를 측정하고 피난시간과 비교하여 적절한 피난이 가능한지에 대한 안전성을 검토하고자 한다.

In this study, river water-based reference materials (RMs), NIER-I08RW and NIER-I09, for trace metal analysis were prepared and certified for Pb, Cd, Cr and Cu with evaluation of uncertainties. The RMs were confirmed to be homogeneous enough to be used as proficiency testing materials since within-bottle homogenieties of the RMs were lower than 0.3 times of targeted standard deviation of proficiency testing. The RMs were distributed to environmental testing laboratories for the proficiency testing and the variation of Z scores of the proficiency testing results were compared for different assigned values. The relative bias, $B_{relative}$, deviations between reference values and consensus values, were lower than ${\pm}$1 except for cadmium of NIERI08RW. The results showed both values were in a good agreement and only 2.9% of Z scores changed by using a different assigned values such as consensus and reference values.

In this study, on-site corporate instructors participated as student-cum-workers in a degree-linked high skills Meister course to improve job competency and practical ability as proposed in the Work-Study Career Vision. Evaluation questions were then developed and their validity was verified by assessing satisfaction related to expected goals in enhancing advanced training guidance and competency as an evaluator. Satisfaction assessment was conducted based on training preparation, training implementation, training effectiveness and training administration. The Delphi Method was adopted and a total of 48 items were developed in 6 categories under 4 main areas. There were 7 evaluation items on the satisfaction of training course development under training preparation, 21 evaluation items related to the satisfaction of Off-JT and OJT courses under training implementation, 16 evaluation items related to the satisfaction of increased competency as an on-site corporate instructor and the satisfaction of enhanced practical skills and skills application at work under training effectiveness, as well as 6 evaluation items to assess satisfaction with administrative support under training administration. The final conformity assessment was conducted based on the stability, content validity ratio, consensus and convergence indicators of the developed items. Results of this study do not only apply to quality management of the high skills Meister course which is being promoted as a pilot project for work-study programs, but also serves as a rationale that may be considered as a basic research tool in the collection of various opinions to derive overall system improvement factors for the work-study high skills Meister course.

This study analyzed the determinants that affect employment retention rate in order to diagnose dynamic employment stability in Korea. For this analysis, we constructed multi-level hierarchical data linking Workplace panel survey data and employment insurance job history data. And the determinants were analyzed using a multi-level analysis model suitable for these data. As result of the analysis, it is estimated that the employment stability is very low in Korea due to the widespread existence of the marginal sectors with low wage level and high level of nonstandard employment. In addition, the results of this analysis show that employment structure of Korea occupies considerable area of short-term employment where employment and unemployment are repeated, and overall employment stability is weak. This fact is likely to be a limiting factor for continued growth, as there is limited opportunity for skill development and skills formation at the corporate and individual levels. According to the results of this analysis, it is required to improve the quality of the employment structure for continuous growth and skill formation.

Focusing market failure and state intervention, this article analyzes the determinants of corporate training in Korea. Analysing the first wave of HCCP(Human Capital Corporate Panel) data produced by KRIVET(Korea Research Institute for Vocational Education and Training), this article finds that even though the skills attainead in corporate in Korea are mostly general(industry-specific), but the market failure in training appears rather small and is confined to the manufacturing industry. And the state intervention in corporate training works only at manufacturing industry, it does not work at new service industry. The results mean that in new service industry, it is difficult to find out the existence of market failure in training due to the positive externalities. Therefore Korea government should look thoroughly into the state intervention in training in new service industry.

The secondary science teachers' professional needs and their preference for training method between off-line and on-line education were investigated. A nation-wide survey was administered to 145 science teachers from 106 secondary schools. The respondents showed high demands on all items. The prominent need was to motivate students learning science. To the contrary. their need for learning more about history and philosophy of science was the lowest. Veteran teachers and high school teachers had higher demands on designing evaluation items, but nonveteran teachers on evaluating the effectiveness of their instruction and updating their scientific knowledge. Teachers preferred the online education as a training method for most items except laboratory activities.

This study was carried out to produce Reference Materials (RMs) for Proficiency Testing (PT) of PCBs in waste analytical laboratories. Two RMs were prepared from used transformer oil samples and PCB free transformer oil by spiking PCBs standard solutions. The spiked PCB RMs were homogenized by mixing and settling up to 90 days. Homogenized concentration of PCBs with Arochlor 1254 (6 ppm), 1254:1260 (1:1) (5 ppm) were observed in 60 days stationary phase but Arochlor 1260 (3.5 mg/L) were observed in 90 days stationary phase. One-way ANOVA test were carried out and showed that the RMs were suitably homogenized, which can be used for proficiency testing. The Relative Standard Deviations (RSDs) of analytical results were 3.51~5.01% for the PCBs RMs in 10 replicates. The expanded uncertainty of PCBs analytical procedure were 0.26~0.49.
