Purpose - The purpose of this paper is to examine the buyer's right to avoid the contract under SGA and CISG. Design/methodology/approach - This paper has conducted literature reviews to analyze the right to avoid the contract of the buyer based on the comparative study. Findings - Under s. 11(3) of SGA, the breach of a condition and an intermediate which deprives the buyer substantially of the whole benefit of the contract may give rise to a right to treat the contract as repudiated. But under Art. 49 of CISG, the buyer has the right to terminate the contract where the seller's failure to performance amounts to a fundamental breach of contract. Regarding the breach of an intermediate and the breach under CISG, the buyer should take into account where the seller's breach is fundamental or not. Moreover, an anticipatory breach can give rise to a right to avoid the contract. The anticipatory breach of a condition justifies termination. The breach of an intermediate and the breach under CISG require an anticipatory fundamental breach of the contract. Under SGA, the buyer has to prove an anticipatory breach in fact but CISG does not require virtual certainty, which SGA has stricter criteria to assess an anticipatory breach. Research implications or Originality - Comparative study helps to understand the nature of provisions under SGA and CISG and suggests practical advice to choose applicable laws. SGA gives more certainty to classify a contractual term. In case of the breach of a condition including the anticipatory breach under SGA, the buyer does not have to ask how much serious the breach is. But CISG requires the fundamental breach of the contract, which means that the buyer has the more burden of proof compared with SGA.

This study analyzes the buyer's remedies for defects in title under DCFR, and it is compared with those of CISG. DCFR adopts a unitary concept of 'non-performance' which is any failure and includes delayed performance and any other performance which is not conformed with the contract. In terms of defects in title, any remedies for non-performance are available under DCFR. Thus. under DCFR, the buyer is entitled to enforce specific performance of obligations, to withhold performance, to terminate for fundamental non-performance, to reduce price, to damage for loss, to require repair, or to deliver a replacement. But under CISG, whether or not defects in title constitute 'non-conformity' is not clear and the majority understands 'non-conformity' does not include title defects. Therefore, the buyer may not has rights to require repair and delivery of replacement unlike DCFR.

In this paper, delay-constrained data transmission is considered over error-prone networks. Network coding is deployed for efficient information exchange, and an approximate decoding approach is deployed to overcome potential all-or-nothing problems. Our focus is on determining the cluster size and its impact on approximate decoding performance. Decoding performance is quantified, and we show that performance is determined only by the number of packets. Moreover, the fundamental tradeoff between approximate decoding performance and data transfer rate improvement is analyzed; as the cluster size increases, the data transfer rate improves and decoding performance is degraded. This tradeoff can lead to an optimal cluster size of network coding-based networks that achieves the target decoding performance of applications. A set of experiment results confirms the analysis.

In recommender systems based on collaborative filtering, measuring similarity is very critical for determining the range of recommenders. Data sparsity problem is fundamental in collaborative filtering systems, which is partly solved by Jaccard coefficient combined with traditional similarity measures. This study proposes a new coefficient for improving performance of Jaccard coefficient by compensating for its drawbacks. We conducted experiments using datasets of various characteristics for performance analysis. As a result of comparison between the proposed and the similarity metric of Pearson correlation widely used up to date, it is found that the two metrics yielded competitive performance on a dense dataset while the proposed showed much better performance on a sparser dataset. Also, the result of comparing the proposed with Jaccard coefficient showed that the proposed yielded far better performance as the dataset is denser. Overall, the proposed coefficient demonstrated the best prediction and recommendation performance among the experimented metrics.

Generally, to product multi-grade oil like engine oil, a sort of mineral base oil is mixed with a fundamental additive package liquid and a polymer liquid as viscosity index improver in order to improve the lubricating property of base oil. That is, engine oil is the mixture of more than two fluids. Specially, a polymeric type liquid cannot be seen as the linear viscosity like Newtonian fluids. In this research, by using the governing equation describing non-Newtonian hydrodynamic lubrication related with the mixture of incompressible fluids based on the principle of continuum mechanics, it will be compared the bearing performance between the mixture of each liquid to be blended and multi-grade engine oil as a single fluid in a high speed hydrodynamic journal bearing. Further, it is to be found the way estimating the performance of the blended multi-grade engine lubricant in a journal bearing in advance before blending by using the physical properties of mineral base oil, fundamental additive liquid and polymer liquid of viscosity index improver. So, it can be reduced the number of trial and error to get the wanted lubricant by selecting the proper volume fraction of each liquid to satisfy the expected performance and estimating in advance the performance of various multi-grade oils before blending. Therefore, it can be shorten the developing time and saved the developing cost.

본 연구에서는 대구 성서 3차 산업단지의 중소기업들을 대상으로 기술개발요인이 기업의 혁신성과에 미치는 영향을 기업특성의 측면에서 실증적으로 분석하고, 기술정책 측면에서의 시사점을 제안하였다. 기술개발요인을 인력, 자금 등의 기반적 요인과 외부 협력 등의 활동적 요인으로 구분하여 독립변수로 사용하였다. 연구의 결과에 따르면, 타기업 및 대학/연구기관과의 활동적 요인은 혁신성과에 유의적으로 긍정적인 영향을 미치고 있는 것으로 나타났으며, 이러한 영향은 기업규모가 평균보다 큰 기업군을 연구대상으로 간주하였을 때 나타났다. 또한 평균보다 큰 기업규모를 보유한 기업은 불확실한 경영환경에서 활동적 요인이 기업의 혁신성과를 보다 향상시키는 중요한 역할을 제공하고 있는 것으로 나타났다. 이러한 결과에 따라 기술개발정책은 인력, 장비 등 기반적 요인의 확충보다는 기업의 협력활동을 촉진시키는데 보다 초점을 두고 추진할 필요가 있으며, 정책 추진시 기업의 규모 등 특성에 따라 상이한 접근을 고려할 필요가 있다고 할 수 있다.
