In mass customization, the focus is variety and customization through flexibility and quick responsiveness. Mass customizers seek to provide personalized, custom-designed products at low prices to give customers exactly what they want and to provide sufficient variety in products and services. The idea of the product family is the most adequate approach to realize mass customization. An understanding of customer needs using functional decomposition becomes necessary to enhance the performance of the product family. This paper focuses on functional architecture modeling based on customer need regarding sub-functions for the product family. A quantitative functional model captures product functionality and customer need. Based on customer need ratings and sub-function, a product-function matrix was created. Additionally, a product-product matrix was generated to provide a similarity index among product families. A case study for implementing the functional architecture modeling was performed on the single use cameras.

To assist radiologists for the characterization of breast masses, Computer-aided Diagnosis(CADx) system has been studied. The CADx system can improve the diagnostic accuracy of radiologists by providing objective information about breast masses. Morphological and texture features were extracted from the breast ultrasound images. Based on extracted features, the CADx system retrieves masses that are similar to a query mass from a reference library using a k-nearest neighbor (k-NN) approach. Eight similarity measures of distance, Euclidean, Chebyshev(Minkowski family), Canberra, Lorentzian($F_2$ family), Wave Hedges, Motyka(Intersection family), and Cosine, Dice(Inner Product family) are evaluated by ROC(Receiver Operating Characteristic) analysis. The Inner Product family measure used with the k-NN classifier provided slightly higher performance for classification of malignant and benign masses than those with the Minkowski, $F_2$, and Intersection family measures.

Purpose - Indonesian economy often receives negative impact from external factors, particularly through trade linkage. To mitigate that impact, the export market and product diversification should be established. Latin America is one of the potential regions to augment the Indonesian export market. Research design, data, and methodology - This study attempts to classify the potential market and product for Indonesian export, particularly in Latin America, by using panel regression, trade complementarity, and export similarity index over the period 2000-2015. Regression was also used to examine whether the presence of the Indonesian Trade Promotion Center (ITPC) can support diversification. Results - Based on regression results, those indexes established Chile, Uruguay, Suriname, and Ecuador as the priority countries with the products: animal and vegetable oils, fats and waxes; chemicals and related products; miscellaneous manufactured articles; commodities and transactions. Conclusions - The results of the regression concludes that the trade complementarity index gave a significant positive effect to boost Indonesian export, whereas, the export similarity index gave a significant negative effect. The regression also conclude that ITPC gave a significant positive impact on Indonesian export. For instance, the government should prioritize those countries and products and also develop ITPC there to optimize Indonesian export.

본 연구는 복합원산지제품에 대한 평가를 파악하기 위해 제품의 카테고리 유사성에 따라 구분하고 매장유형 별로 비교해 봄으로써, 복합원산지제품을 생산하는 기업들에게 실무적으로 활용 가능한 대안을 제시하고자 하였다. 이를 위해 본 연구는 복합원산지제품의 평가를 제품카테고리 별로 비교하기 위해 소비자들의 심리적 기저를 바탕으로 공적사치재, 공적필수재, 사적사치재, 사적필수재로 구분하여 분석에 적용하였으며, 매장의 유형은 백화점/직영점, 아울렛/할인매장으로 구분하여 측정의 정교화를 기하고자 하였다. 검증결과, 제품유형과 매장유형에 따라 브랜드평가 및 매장평가는 상호작용효과가 있는 것으로 나타났다. 구체적으로 공적사치재의 경우 브랜드평가와 매장평가 모두 아울렛/할인매장이 백화점/직영매장 보다 긍정적인 평가가 나타나는 것으로 분석되었으며, 사적필수재의 경우는 브랜드평가에서 큰 차이를 보이지 않았으나 매장평가에서 백화점/직영매장이 아울렛/할인매장 보다 상대적으로 긍정적인 평가를 보이는 것을 확인할 수 있었다. 이를 통해, 각각의 제품 별로 판매매장 유형에 따라 소비자들의 평가가 달라질 수 있음을 검증하였다.

In this paper, the metal forming process is caused of rise of the unit cost of production in increase of the lead-time and cost because of manufacturing final product through a few the number of processes. Flow control complex forming is proposed to put into formulation in order to apply cold forging from conventional approximate similarity theory, and the forming loads of the real material(AISI 1008) can be calculated by put at the new similarity formula the load by plasticine model material experiment through hub clutch. In order to reduce lead-time and cost the technology is used to manufacture with lower die of this product. By the application synthetic resin as the raw material, it is have the merit such short lead-time, low cost, good surface finish etc., as compared with the machine work.

본 연구는 기존의 브랜드 확장 연구를 기반으로 하여 소비자들이 인터넷 브랜드 확장을 평가할 때 영향을 미치는 요인들에 관하여 연구하였다. 특히, 본 연구에서는 온라인 특성을 감안하여 인터넷 벤더에 대한 신뢰라는 변수를 새롭게 도입하였고, 이러한 신뢰가 인터넷 브랜드 확장 평가에 미치는 영향을 알아보았다. 사례 분석 결과 인터넷 브랜드는 확장 제품의 유사성의 영향보다는 소비자 경험에 의해 축적된 인터넷 벤더에 대한 신뢰가 인터넷 브랜드 확장 평가에 긍정적인 영향을 주는 것으로 나타났다.

소비자가 남긴 댓글이나 상품평은 상품기획의 주요 정보가 될 수 있다. 본 논문에서는 버티컬 무소음 마우스 7,300개에 대한 온라인 댓글을 딥러닝 기술인 Word2Vec을 이용하여 유사도 분석을 시행하였다. 유사도 분석결과 클릭 키워드에 대한 장점으로 소리(.975), 버튼(.972), 무게(.971)가 분석되었으며 단점은 가볍다(.959)이었다. 이는 구매 상품에 대한 소비자의 의견, 태도, 성향 및 서비스에 대한 포괄적인 의견들을 데이터화 하여 상품의 특징을 분석할 수 있는 의미있는 과정 이라고 볼 수 있다. 상품기획 프로세스에 딥러닝 기술을 통한 소비자의 감성분석자료 포함시키는 전략을 적용한다면 상품기획의 시간과 비용투자의 경제성을 높일 수 있고 나아가 빠르게 변화하는 소비자의 요구사항을 적기에 반영할 수 있을 것으로 생각된다.

The number of matched peaks (NMP) is estimated as the spectral similarity measure in tandem mass spectral library searches of small molecules. In the high resolution mode, NMP provides the same reliable identification as in the case of a common dot-product function. Corresponding true positive rates are ($94{\pm}3$) % and ($96{\pm}3$) %, respectively.

The objective of this research is estimating the location of interested sound source by using the similarity between a beamformer output in time domain and the candidate signal. The waveform of beamformer output at the location of sound source is similar with the waveform emitted by that source. To estimate the location of sound source by using this feature, we define quantified similarity between candidate signal and beamformer output. The candidate signal describes the signal which is generated by interested source. In this paper, similarity is defined by four methods. The two methods use time vector comparison, and the other two methods use time-frequency map or linear prediction coefficients. To figure out the results and performance of localization by using similarities, we demonstrate two conditions. The one is when two pure tone sources exist and the other condition is when several bird sounds exist. As a consequence, inner product with two time-vectors and structural similarity with spectrograms can estimate the locations of interest sound source.
