최근 경기침체와 물가상승으로 소비자들은 구매행위에 있어서 가치 지향적이고 합리적인 구매를 좇아가게 되었고, 이러한 소비패턴의 변화는 유통업체 브랜드가 대형마트의 상품구성에서 차지하는 비중이 점점 커지는 변화를 불러왔다. 또한 온·오프라인의 경계가 무너지면서 인터넷 쇼핑몰 간의 경쟁이 치열해지고 이러한 위기를 타파하고자 온라인 소매업체는 경쟁우위 전략 방안의 하나로 유통업체 브랜드를 개발하기 시작하였다. 그러나 오프라인에 비해 인터넷 쇼핑몰의 유통업체 브랜드는 관리가 어려운 실정이다. 이에 본 연구는 인터넷 쇼핑몰을 이용해본 경험이 있는 소비자를 대상으로 설문을 진행하였다. 구체적인 측정은 유통업체 브랜드 평가와 소매업체 브랜드 자산이 유통업체 브랜드 태도에 미치는 영향을 살펴보았다. 또한 소매업체 브랜드 자산 속성이 유통업체 브랜드 평가와 유통업체 브랜드 태도간의 관계를 조절하는지 확인하였다. 분석 결과, 지각된 가격은 유통업체 브랜드 태도에 긍정적인 영향을 미치는 것으로 나타났고, 지각된 위험은 유통업체 브랜드 태도에 부정적인 영향을 미치는 것으로 나타났다. 또한 소매업체 브랜드 자산의 속성 가운데 소매업체 브랜드 연상과 소매업체 브랜드 충성도는 유통업체 브랜드 태도에 긍정적인 영향을 미치는 것으로 나타났으며, 이들은 유통업체 브랜드 평가와 유통업체 브랜드 태도 간의 관계에 있어 조절적 역할을 하는 것으로 확인되었다. 본 연구를 통해 유통업체 브랜드뿐만 아니라 소매업체 브랜드 자산을 구축하고, 나아가 마케팅 전략 및 유통업체 브랜드 성공에 도움이 될 것으로 기대한다. Recently, due to the recession and inflation, consumers have pursued value-oriented and rational purchasing behavior, and this change in consumption pattern has led to the different phase in the proportion of private label brands in the merchandise composition of large-sized discount stores. Also, as the boundaries of on-line and off-line retailing are getting ambiguous, the competition among Internet shopping malls became severe. In order to overcome such a crisis, online retailers started to develop the private brand as one of the strategies of competitive advantage. However, it is difficult to manage private brands in Internet shopping environment compared to store-based retailers. In this study, we surveyed consumers who had experience shopping private brand products at internet shopping malls. Specifically, we examined the effects of private brand product evaluations (price value and quality risk) and retailer`s house brand equity on attitude toward the private brand provided by the online retailers. In addition, we tried to find whether the attributes of retailers brand equity moderate the relationship between the private brand product evaluations and the attitude toward the private brand. As a result, perceived price has a positive effect on attitude toward private brand, and perceived risk in quality has a negative impact on it. Also, among attributes of retailer brand equity, association and loyalty of house brand positively affect attitude toward private brand, and these have a moderating role in relationship between evaluations of and attitude toward private brand.

As critical components of the text, punctuation marks serve many functions: the end of sentence, the speaker s tone, the meaning of the word and the logic of the text, among others. This paper, therefore, is to discuss the translation strategy in accordance with the comparison of Korean-Chinese punctuation marks in morphology and to illustrate how important punctuation marks are in translation. Accordingly, in this paper Korean-Chinese translations are compared through concrete examples in the following methods. The punctuation marks are (a) transferred as they are, (b) having the form changed, (c) having the position changed, (d), deleted, and (e) added. Although this may not be the most detailed approach to this subject, I’m confident that the results of this study will be helpful for an accurate Korean-Chinese translation, especially when it involves punctuation marks.

Noise, Vibration and Harshness (NVH) is a comprehensive issue of manufacturing quality that gives the purchaser a superficial feeling. The NVH performance of the vehicle has undoubtedly become an important factor and basis for consumers. When the internal combustion engine is working, it generates a strong noise thus making it necessary to reduce the vibration and noise. The noise of diesel engine is divided into acoustic and structural radiation noise according to different radiation paths. The structure radiated noise is mainly caused by the combustion noise and mechanical transmission noise, while mechanical transmission noise is mainly generated by the meshing gears in the diesel. This paper aims to solve the problem of a diesel engine abnormal gear whine noise under idling conditions with a combination of simulation and experiment. By gear micro-modification, the gear train whine noise is reduced by minimizing the PPTE of the gear train. The comparison of the simulation to benching testing shows a good correlation. It provides an optional solution to the modification proposal of the engine gear train, which uses the similar structure for the engine. Future work will dwell on a better understanding of the gear rattle noise, which will be discussed later.

The transportation is almost dependent on a single fuel petroleum with transportation energy dilemma. Hybrid Electric Vehicle(HEV) technology holds more advantages on efficiency improvements for petroleum consumption at the transportation. And bearing is recognized as the important component of gearbox. Gearboxes for HEV transmission have been ensured the highest reliability over some years in withstanding high dynamic loads. At the same time, the demands of lightweight design and cost minimization are required by thought-out design, high-quality material, superior production quality and maintenance. In order to design a reliable and lightweight gearbox, it is necessary to analyze bearing rating life methods between standard and different bearing companies with calculation methods for modification factors. In this paper, the influence of life time of bearings will be pointed out. Bearing contact stress and load stress distribution of HEV gearbox are obtained and compared with Romaxdesigner and BearinX. And the unequal wear of the left bearing for the gearbox intermediate shaft is investigated between simulation and test.

In recent years, world is faced with a transportation energy dilemma, and the transportation is dependent on a single fuel - petroleum. However, Hybrid Electric Vehicle(HEV) technology holds more advantages to reduce the demand for petroleum in the transportation by efficiency improvements of petroleum consumption. Therefore, there is a trend that lower gear noise levels are demanded in HEV for drivers to avoid annoyance and fatigue during operation. And meshing transmission error(T.E.) is the excitation that leads to the tonal noise known as gear whine, and radiated gear whine is also the dominant source of noise in the whole gearbox. This paper presents a method for the analysis of gear tooth profile and lead modification, and the predictions of transmission error and load distribution are shown under one loaded torque for the 1<SUP>st</SUP> gear pair of HEV gearbox. The test is also obtained before tooth micro-modification under the torque. At last, the appropriate tooth modification is used to minimize the transmission error and load distribution under the loaded torque. It is a good approach which the simulated result is used to improve the design in order to minimize the radiation gear whine noise.

Transmission error (TE) is the most important cause of gear noise and vibration because TEs affect the changes of the force and the speed of gears. TE is usually expressed as an angular deviation, or a linear deviation measured at the pitch point and calculated at successive positions of the pinion as it goes through the meshing cycle. Accurate measurement of TE for gear transmission will provide a reasonable basis for gear design, manufacturing processes and quality control. Therefore, in order to study the accuracy of the gear transmission, stability, TE, vibration and noise after gear micro-geometry modification, a gear transmission test rig is proposed in this paper, which is based on the existing technical conditions, by using reasonable testing methods, hardware and a signal processing method. All of the details and the experience can be taken into consideration in the next upgraded test rig.

장기(Qi Zhang),강재화(Jae-Hwa Kang),류성기(Sung-Ki Lyu) 한국기계가공학회 2011 한국기계가공학회지 Vol.10 No.4

Nowadays, modern gearboxes are characterized by high torque load demands, low running noise and compact design. Also durability of gearbox is specially a major issue for the industry. For the gearbox which used in wind turbine, gear transmission error(T.E.) is the excitation that leads the tonal noise known as gear whine, and radiated gear whine is also the dominant source of noise in the whole gearbox. In this paper, tooth modification for the high speed stage is used to compensate for the deformation of the teeth due to load and to ensure a proper meshing to achieve an optimized tooth contact pattern. The gearbox is firstly modeled in Romax software, and then the various combination analysis of the tooth modification is presented by using Windows LDP software, and the prediction of transmission error under the loaded torque for the helical gear pair is investigated, the transmission error, contact stress, root stress and load distribution are also calculated and compared before and after tooth modification under one torque condition. The simulation result shows that the transmission error and stress under the loads can be minimized by the appropriate tooth modification.

Nowadays, lower gear vibration and noise are necessary for drivers in automotive gearbox, which means that transmission gearbox should be optimized to avoid noise annoyance and fatigue before quantity production. Transmission error (T.E.) is the excitation factor that affects the noise level known as gear whine, and is also the dominant source of noise in the gear transmission system. In this paper, the research background, the definition of T.E. and gear micro-modification were firstly presented, and then different transmission errors of loaded torques for the spur gear pair were studied and compared by a commercial software. It was determined that the optimum gear micro-modification could be applied to optimize the transmission error of the loaded gear pair. In the future, a transmission test rig which is introduced in this paper is about to be used to study the T.E. after gear micro-geometry modification. And finally, the optimized modification can be verified by B&K testing equipment in the semi-anechoic room later.
