본 논문은 목자판과 수면이 포함된 시차가 있는 연속적인 두 영상을 이용하여 수면위치를 탐색하는 방법과 그 적용성을 평가한 결과를 기술한다. 수위표 상단으로부터 특정 크기의 직사각형 검사영역을 설정하고 짧은 시차를 가진 두 영상의 동일한 위치의 검사영역에 대해 상관계수를 산정한다. 이렇게 함으로써 물의 흐름으로 픽셀 농도가 변화하는 수역과 픽셀 농도가 고정되어 있는 육역을 구분한다. 제안한 기법을 검증하기 위해 실험실에서 촬영한 사진을 분석하였다. 분석결과 검사영역의 크기에 따라 상관계수 특성이 달라짐을 확인하였으며, 검사영역이 수위표 전체 폭에 걸쳐 있는 경우에 상관계수에 따른 수면특성이 뚜렷이 나타나 제안된 기법이 수면을 찾는데 활용될 수 있음을 확인하였다. 또한 시차가 있는 두 영상의 상관분석을 통한 수위측정방법을 통해 기존 영상수위계의 오염된 영상에서 오차범위가 10~42cm 발생했던 것을 2.6cm 이내로 줄일 수 있었다. 이 방법은 기존 영상수위계의 방법을 보완하여 수위 측정 성능을 높이는데 활용될 수 있을 것이다.

The nature of genetic variation and diversity among the 65 multivoltine silkworm genotypes was evaluated for 16 post cocoon characters. The components of genetic variation revealed higher PCV (60.487%) and GCV (44.56%) for evenness (variation 1) followed by cohesion (PCV=55.38%, GCV=40.36%) and non-broken filament length (PCV=32.05%, GCV=31.28%). The higher heritability ($h^2$ in broad sense) was observed for boil-off loss (95.6%) followed by non-broken filament length (95.22%). The both genotypic and phenotypic correlation indicated significant positive correlation of filament length with non-broken filament length, silk recovery, raw silk, neatness, and low neatness; and negative correlation with denier, renditta and silk waste. The principal component analysis (PCA) revealed 75.381 % of total variance from the five principal components extracted. On the basis of Mahalonobis' $D^2$ values (Ward's minimum variance), the sixty-five multivoltine silkworm genotypes were classified in to 9 clusters with substantial inter and intra cluster distances. Number of genotypes included in different clusters varied from 3 to 17. The results indicated that the optimum distance obtained in cluster VII (15.059) along with higher cluster mean values especially for filament length, non broken filament length, renditta, silk recovery, silk waste, and raw silk emphasized the utilization of these genotypes in the conventional silkworm breeding programme for improvement of multivoltine silk fibre quality. The possibility of exploiting genetic variation in post cocoon traits for efficient breeding programme is discussed.

This study identifies the commercialization success factors that can be an important indicator for the transfer and commercialization of national R&D results in the agricultural sector. Unlike other industries, the agricultural sector has a non-systematically scaled and processed industrial structure, and R&D is led by government rather than the private sector. Although the quantitative performance of national agricultural R&D, especially the number of patents and publications, has increased rapidly with the quantitative expansion of the government R&D budget, the technology commercialization of the results of agricultural R&D has been accompanied by difficulties for SMEs. Therefore, this study summarized the success factors for commercialization of state-owned technologies presented in previous studies, and based on them, analysed the success factors for commercialization specific to the agricultural sector. It also conducted a questionnaire survey using Delphi and focus group interviews (FGI) with experts from academia, research and industry, and a survey of agricultural companies to derive success factors for commercialization in the agricultural sector using logistic regression analysis. As a result, five indicators with positive correlation and three indicators with negative correlation within technology characteristics, suppliers, adopters, policy and market factors were finally derived as key factors for agricultural commercialization. In the future, it is expected that independent factor analysis of the food and seed sectors, which have independent industry characteristics from the agricultural sector, will be needed.

There are six perspectives of fit in strategy research, each implying distinct theoretical meaning and requiring the use of specific analytical schemes. But there is a few literature of the perspective in the discipline of Organizational Decision-Making and DSS. This study is a prior research which objective is to investigate the perspective of fit emprically in the discipline. The data were collected throughout the sampled business firms with premade questionaire and analysis were conducted with correlation analysis, regression, ANOVA and so forth. The research finding is that both predictors, one of which can be the moderator, influence the performance, and that the joint-effect of them influence the performance. Thus,'Fit as Moderation' would be suggested to be a proper model for the research in the discipline of Organizational Decision-Making and Decision Support Systems.

The main objective of this study is to analysis the relationship between productivity measurement model which describe and explain R&D(Research & Development) productivity based on production function of Cobb-Douglas and the structure of the R&D investment. The model focuses on the variables related to R&D investment in order to measure the efficiency of R&D largely. So, the proposed model describe the relationship between output(or / input) and factors of production such as capital cost, labor cost and R&D expense, etc. These factors are associated with a signigicant positive correlation between productivity and R&D investment.

In general, non-stationary or chaos time series forecasting is very difficult since there exists a drift and/or nonlinearities in them. To overcome this situation, we suggest a new prediction method based on multiple model TS fuzzy predictors combined with preprocessing of time series data, where, instead of time series data, the differences of them are applied to predictors as input. In preprocessing procedure, the candidates of optimal difference interval are determined by using con-elation analysis and corresponding difference data are generated. And then, for each of them, TS fuzzy predictor is constructed by using k-means clustering algorithm and least squares method. Finally, the best predictor which minimizes the performance index is selected and it works on hereafter for prediction. Computer simulation is performed to show the effectiveness and usefulness of our method.

The interactive diffusion of technological knowledge across industries is reckoned as the principal determinant of the industrial competitiveness in the knowledge-based economy. The flow of technological knowledge takes place through two major channels, embodied and disembodied ones. This paper analyzes, from the dynamic perspective, the functional role and changing relationship of major Korean industries in terms of embodied and disembodied technological knowledge flow-structures during 1980s. We measure, as a proxy, the knowledge by the number of R&D researchers. The inter-industrial embodied and disembodied knowledge flows are measured by the input-output technique and the technological similarity is quantified according to the R&D researchers'academic background, respectively. Based on the comparative and correlation analysis between the two knowledge flow-structures, it is found that there exist, albeit not striking, both similarities and differences between them. However, interestingly and indicatively, we find that the two flow structures become more similar as time goes by. Some explanatory comments and policy implications are presented.
