기술분야의 발전이 거듭됨과 병행하여, 산업계의 설계 해석 부서에서 CAE의 중요성은 컴퓨팅 시 스템과 더불어 더욱 강조되고 있다. 슈펴 컴퓨팅 파워의 필요성은, 첫째, applied mechanics의 advanced 해석분야, 둘째, 대형 엔지니어링 문제해석 결과처리 (data acquisition & management), 셋째, real time response와 integrated 엔지니어링 시스템개발 (CAD/CAM 데이터와의 연계성) 등의 측면에서 나타난다고 볼 수 있다. 원가, 안정성 그리고 신뢰성은 모두 만족시키는 효율적인 방안으로서는 대형 수퍼 컴퓨터와 마이크로 컴퓨터의 중간 역할을 할 수 있는 hybrid type의 미니 수퍼 시스템, 즉 departmental highly-parallel 시스템의 등장이 필수적이라고 할 수 있다. 또한, 산업계의 설계 해석 지원과 관련, 구조, 유체, 동력학 등의 분야별 응용 문제와 numerical formulation등의 특성에 적합한 시스템 configuration과 프로세싱이 개발되어야 한다. 이는 실 수요자의 상황에 맞는 "목적성 전용 machine"의 등장이 가능해 질 것으로 판단된다. 향 후, vectorization 그리고 parallelization 된 소프트웨어의 가용성이 극복해야 할 큰 과제로 남아 있 다고 본다.

금융시장에서의 경쟁이 치열해지면서 이제 국내 소비자금융기관들에게 수익성위주의 내실경영은 피할 수 없는 지상과제로 부상하고 있다. 이러한 목표를 성취하기 위해서는 우량고객을 위주로 한 기반강화와 철저한 사후관리를 통한 수익성향상이 이루어져야 한다. 특히, 자금운용처로 부상하고있는 개인고객들을 대상으로 하는 효과적인 대출마케팅의 수행은 소매금융기관들의 수익성제고에 절대적이라고 할 수 있다. 즉, 수익성을 지향하기 위해서는 고객관리를 보다 더 철저하게 하여야 하며 이를 위해서는 신용 및 수익성에 근거해서 산출된 평점에 따라 개인별 관리를 차별화하는데 있다고 할 수 있다. 본 연구에서는 우량고객들을 대상으로 대출마케팅을 활성화시키기 위한 고객평점모형의 효과성에 대해서 고찰해 보고자 하였다. 이를 위해서 신용평점모형에 대해서 자세히 알아보고 이어서 수익성에 근거한 평점모형에 대해서도 이론적으로 살펴보았다. 그리고 두 모형의 효과성을 비교하기 위해서 판별분석을 사용하여 우량 및 불량고객에 대한 예측력을 분석해 보았다. 분석결과 제1종오차에 대해서는 신용평점모형이, 제2종 오차에 대해서는 수익성평점모형이 보다 정교한 예측력을 나타냈다. 결론적으로 두 모형의 사용이 병행되는 통합적인 고객평점모형의 적용이 제안되어 졌다.

The purpose of this study was to identify sector-wise issues that need to be improved for the overall development of the mushroom industry and to prioritize these tasks based on an analysis of the current state of this industry in Korea. To this end, we classified the domestic mushroom industry into four sectors: production, processing, marketing, and export and distribution, and identified major tasks for the improvement of each of these sectors. A total of eleven issues that could be improved were selected, including three each in the production, marketing, and export and distribution sectors, and two in the processing sector. An analytical hierarchy process (AHP) was utilized to identify the issues in each sector that would need to be handled on a priority basis. A questionnaire-based survey was also conducted to gain relevant insights and suggestions from 32 experts in this industry. The present study is significant because it highlights sector-wise priority areas that could be supported by policies and legal measures for the overall development of the mushroom industry.

As the Korean economy grew, employment expanded steadily, with the number of economically active people increasing and the employment-to-population rate also increasing. However, the working age population started to decline in 2017, and the employment of women and young people has been sluggish. The proportion of non-salaried workers in Korea is much higher than in other OECD countries, and is also excessive, considering Korea's income levels. In addition, the proportion of non-regular workers and the proportion of workers employed at small companies are particularly high among salaried workers. In light of these characteristics of Korean employment, the urgent problems facing the employment structure can be summarized by the deepening dual structure of the labor market, the increase in youth unemployment, sluggish female employment figures, and an excessive share of self-employment. Overall, it is seen that labor market duality is the main structural factor of the employment problems in Korea. Therefore, in order to fundamentally address this employment problem, it is necessary to concentrate policy efforts on alleviating labor market duality.

The purpose of this study is to examine effects of constraint-induced movement therapy(CIMT) and/or cognitive-perceptual training(CPT) on the change of hand function in cerebrovascular accident(CVA) patients and to evaluate the change in the amount and quality of use of the affected upper extremity in performing daily living tasks. The subjects of study were 10 patients who had been under rehabilitation for more than three months after CVA onset. They were all determined as mild cognition impairment according to NCSE or MVPT test. For CIMT group, to restrict the movement of the unaffected hand the subjects had been worn modified resting arm-splint in daytime for 4 weeks. For CIMT+CPT group, the subjects were performed CPT with CIMT and control group had been under conventional occupational therapy for the same period. CIMT+CPT group showed significant improvement in simulated feeding, lifting large light objects, and lifting large heavy objects of Jebsen-Taylor Hand Function Test. CIMT group also showed significant improvement compared with control group. The mean changes of the amount of use(AOU) of the affected arm had a statistically significant difference among groups (p<.05). While CIMT+CPT group had the biggest change in the quality of movement(QOM) of upper extremity of the affected side, CTL group showed the smallest change. Both CIMT and CIMT+CPT groups had statistically significant difference in the change in the quality of movement in upper extremity of affected side with CTL group(p<.05), but there was not significant difference between CIMT group and CIMT+CPT group. CIMT performed to the patients of stroke, with mild impairment in cognitive perceptual abilities showed the improvement in hand movement and AOU and QOM of upper extremity in the affected side and the combination of CIMT with CPT showed synergic effects.

Microfilm has been used as an important media for enhancing the long term preservation and improving access to records. However, because of technological changes, there have been discussion about whether we should keep using microfilm. This paper presents survey results to review the preservation methods such as microfilming and digitization. The content is organized according to the trends found in the survey from six archives and libraries, including Germany, France, the United Kingdom, and Japan. Moreover, we refer to other papers from the USA and Japan to require further review if we can accept digitized records as the original records, etc. The rest consists of four parts: the use of microfilm as a storage media for preservation, the authenticity of digitized records, the management of records on microfilm, and the preservation of electronic media. Finally, we would like to suggest the way to improve preservation systems and digitize records more widely.

In this study, for the purpose of reflection level analysis of high school students in HW design learning which is based on online simulation, we carried out 5 lessons of HW learning and analyzed there reflection levels for 5 individual time of reflection content. The reflection level analysis results for each time of learning shows that the reflection level of the $3^{rd}$ time learning of D-Flip Flop is the highest score with 1.23. The correlation analysis result between the reflection contents presents that high positive correlation between learning content and task resolving method(r=.781, p<.01), and negative design correlation between task resolving method and alternative resolving method. The HW learning satisfaction survey result shows 4.2, and most of the participant students provided opinions that the HW design learning is required and current learning contents is a bit difficult to follow. We could recognize HW design learning is required to have composition of curriculum with basic and advanced contents, and on-off lines combined.

The purpose of this research is to study the meanings and characteristics of qualitative research method in LIS. As the philosophy and epistemology of qualitative research are widely different from those of quantitative research, the meaning of validity and reliability must be interpreted in its ow9 structure and dimension. Essentially qualitative researchers seek to understand and interpret the world of others from their own viewpoints which basically tend to be subjective. Accordingly, qualitative researchers‘ understandings and interpretations are met with readers' subjectivity. By carefully analyzing the nature of qualitative research in LIS, I tried to point out some problems in terms of validity and reliability and practical strategies. Six problems issued in the qualitative research method are presented.
