This paper presents an optimization method to determine the shoulder height of an angular contact ball bearing by 3D contact analysis using nondimensional-shaped variables. The load analysis of the ball bearing is performed to calculate the internal load distributions and contact angles of each rolling element. From the results of bearing load analysis and the contact geometry between the ball and inner/outer raceway, 3D contact analyses using influence function are conducted. The nondimensional shoulder height and nondimensional load are defined to give the generalized results. The relationship between the shoulder height and radius of curvature of the shoulder under various loading conditions is investigated in order to propose a design method for the two design parameters. Using nondimensional parameters, the critical shoulder heights are optimized with loads, contact angles, and conformity ratios. We also develop contour maps of the critical shoulder height as functions of internal loads and contact angles for the different contact angles using nondimensional parameters. The results show that the dimensionless shoulder height increased as the contact angle and dimensionless load increased. Conversely, when the conformity ratio increased, the critical shoulder height decreased. Therefore, if the contact angle is reduced and the conformity ratio is increased within the allowable range, it will be an efficient design to reduce the shoulder height of ball bearings.

This study aimed to provide the most accurate analysis possible regarding the buyer's duty to examine goods and give notice, or the like, of non-conformity to the seller under Belgian law in comparison with the CISG and CESL. Even though Belgium is the capital of the Europe Union, most of its laws remain untranslated in English. Therefore, this study may offer key insights into the specificities of Belgian law, which while being derived from the French Napoleon Code has its own practices coded into its Case Law. It also makes a comparison with the new CESL and CISG in order to evaluate their respective influence on national law and other infructuous attempts to harmonize Belgian law for the internal European market. Evaluating the differences of each system in the spirit of comparative law may be a good basis for the development of laws in each jurisdiction.

CISG Article 50 contains the remedy of price reduction but limits it if the seller has a right to cure. Reduction of price presupposes that the seller delivers non-conforming goods, and that the buyer decides to accept them nevertheless. The remedy of price reduction differs from all other remedies provided in CISG with regard to it effects and to the time-limits. As to the time-limits, unlike Articles 46 and 49, Article 50 does not contain the element within a reasonable time. CISG imposes no period of time for his reducing the price. The buyer's right to declare a reduction of the price is expressly subject to the seller's right to remedy any failure to perform his obligations pursuant to Articles 37 and 48. The problem lies in determining from where to take the figures for comparing the value of the goods contracted and of those delivered. The price level in this place will usually determine his considerations as to resale or repair of the defective goods. The buyer must examine the goods, or cause them to be examined, within, as short a period as is practicable in the circumstances. The buyer loses the right to rely on a lack of conformity of the goods if he does not give notice to the seller specifying the nature of the lack of conformity within a reasonable time after he has discovered it or ought to have discovered it.

Purpose: Total scalp irradiation (TSI) is a rare but challenging indication. We previously reported that non-coplanar intensity-modulated radiotherapy (IMRT) was superior to coplanar IMRT in organ-at-risk (OAR) protection and target dose distribution. This consecutive treatment planning study compared IMRT with volumetric-modulated arc therapy (VMAT). Materials and Methods: A retrospective treatment plan databank search was performed and 5 patient cases were randomly selected. Cranial imaging was restored from the initial planning computed tomography (CT) and target volumes and OAR were redelineated. For each patients, three treatment plans were calculated (coplanar/non-coplanar IMRT, VMAT; prescribed dose 50 Gy, single dose 2 Gy). Conformity, homogeneity and dose volume histograms were used for plan. Results: VMAT featured the lowest monitor units and the sharpest dose gradient (1.6 Gy/mm). Planning target volume (PTV) coverage and homogeneity was better in VMAT (coverage, 0.95; homogeneity index [HI], 0.118) compared to IMRT (coverage, 0.94; HI, 0.119) but coplanar IMRT produced the most conformal plans (conformity index [CI], 0.43). Minimum PTV dose range was 66.8%-88.4% in coplanar, 77.5%-88.2% in non-coplanar IMRT and 82.8%-90.3% in VMAT. Mean dose to the brain, brain stem, optic system (maximum dose) and lenses were 18.6, 13.2, 9.1, and 5.2 Gy for VMAT, 21.9, 13.4, 14.5, and 6.3 Gy for non-coplanar and 22.8, 16.5, 11.5, and 5.9 Gy for coplanar IMRT. Maximum optic chiasm dose was 7.7, 8.4, and 11.1 Gy (non-coplanar IMRT, VMAT, and coplanar IMRT). Conclusion: Target coverage, homogeneity and OAR protection, was slightly superior in VMAT plans which also produced the sharpest dose gradient towards healthy tissue.

The purpose of this study is to analyze one of CIETEC(China International Economic and Trade Arbitration Commission) Award on the dispute arising from Cotton Sale Contact which deals with damages and reduction of the price. Especially this case focused on the effect of reduction of the price to damages. The purpose of damages is to place the aggrieved party in as good a position as if the other party had properly performed the contract. So court costs and attorney's fee should be regarded as the loss, because these are caused by consequence of the breach which is recoverable. With the same reason, overpaid taxes should also regard as the loss. It is not impossible, however, to claim both damages and reduction of the price for same loss at the same time. It means buyer could not claim damages for the same loss, once he already claimed reduction of the price. So Korean companies should consider which remedy is proper to himself under the circumstances. He should choose reduction of the price when market price is down. In case of rising market price, he should consider follows: first, it is better to choose damages based on current price(Art.76), if upswing of non-conformity price is higher then upswing of market price. Second, it is better to choose general rule for measuring damages(Art.74), if upswing of market price is higher then upswing of non-conformity price.

This study describes the buyer's remedies regarding defects in title under CISG. Although CISG stipulates the seller's liability for the delivery of conforming goods physically at Art. 35 and legally at Art. 41 and Art. 42 respectively, the buyer's remedies are not distinguished between non-conformity governed by Art. 35 and defects in title governed by Art. 41 and Art. 42. If the seller does not fulfill his obligation under Art. 41 and Art. 42 to deliver goods which are free from third party claims, the buyer should pay attention to which remedies are available under CISG. Under CISG, for defects in title in the delivered goods, the buyer is entitled to require performance in Art. 46 (1) unless he has resorted to a remedy which is inconsistent with this requirement, to declare the contract avoided by strictly limiting the situation in which the failure by the seller to perform his obligation amounts to a fundamental breach of contract in Art. 49, to claim damages in Art. 74, and to suspend the performance of his obligation where it becomes apparent that the seller will not perform a substantial part of his obligation in Art. 71 (1). Unlike Art. 35 non-conformity, the buyer may not require delivery of substitute goods under Art. 46 (2), claim repair under Art. 46 (3), and declare price reduction for title defects under Art. 50.

In this paper, in order to achieve slim and light liquid crystal display, we examine the optical conditions that can obtain uniform light with higher optical efficiency over whole light guide plate (LGP) through simulation. Furthermore, to overcome the issues of hot spot in front of red, green, and blue light emitting diodes (RGB LEDs) source and non-uniform color mixing, we propose four shaped color mixing bars tied up with the LGP and check the optical characteristics of the LGP with them by simulation. Consequently, we could know the optical conditions of improving optical efficiency and optical uniformity in the LGP through the optical design. Also we confirmed that the issues of the hot spot and non-uniform color mixing in edge type LED could be solved by using the ${\bigwedge}$-shaped window color mixing bar.

We investigate the impacts of tariff, tariff-rate quota, conformity assessment, and traceability requirements set by the rice importers using panel data of 17 rice exporters exporting to 119 countries in two years 2015 and 2018, using both Ordinary least square (OLS) and Poisson pseudo maximum likelihood (PPLM) methods. Results from our gravity models strongly indicate that tariff and tariff rate quota remain significantly detrimental to the world's rice exporters because these measures place downward pressure on the rice exporters' prices and the importers' import quantity, creating barriers to market participation. Our study also provides strong evidence about the role of origin certificates in allowing rice exporters to gain access to foreign markets. Meanwhile, regulatory standards such as traceability requirements and logistical and distributional requirements imposed by the rice importers are found to be major obstacles to rice importation from less-developed countries. Our study provides insights into tariff and non-tariff barriers existing in the global rice market, which is likely to assist policymakers operating in developing countries to help shape their policies and bolster rice competitiveness.

The CISG does not stipulate the subject of the burden of proof, and in the arbitral award, the buyer is liable for proof compared to the seller for nonconformity of the product. Without a unified interpretation of the burden of proof of non-contractual goods, confusion of uncertainty may increase if the parties to the sale contract have a dispute due to the trade in goods. It is an important issue to create a unified regulation on this because the courts or arbitration agencies of the Contracting States of the CISG interpret and apply the "seller's obligation to conform to the goods contract" stipulated in this Convention in various ways. In this study, in the case of international Sales of Goods there is a tendency to prefer arbitration through arbitration agencies in the dispute, so the subject of burden of proof is analyzed through arbitration cases applied by CISG as the governing law. Most international commodity trading around the world is regulated by this Convention, but according to the rigid convention regulations, it is analyzed and interpreted through cases where this convention is applied to each country's international arbitration, suggesting the need for a rigid CISG revision.

The purpose of this study compare the difference between purchaser of counterfeit goods and non-purchaser about how self-esteem and conformity influence upon purchase intention of luxury counterfeits goods. Until existing research on purchase intention of luxury counterfeit goods have focused on the consumers' sense of superiority such as conspicuous consumption, hedonic consumption and symbolic consumption. This thesis, however, has focused on individual's psychological variables such as self-esteem and influence of reference group. The results are as follows. The purchaser of counterfeit goods tend to depend on others heavily and show a high purchase intention. On the other hand, the non-purchaser with high self-esteem are less inclined to buy counterfeit goods, and purchase intention level will also be lowed down. This thesis tries to support the assumption that personal psychological difference exist between purchaser and non-purchaser, and this result seems to correspond with the preceding studies.
