Purpose - This study attempts to examine the impacts of consumers' perceived service convenience of retailers on various service performance metrics such as service quality and customer satisfaction. It also tries to investigate differences in the importance of service convenience dimensions on service performance between a department store and a general super market. Research design, data, and methodology - The four hypotheses in this study were proposed and tested. Two hypotheses were on the causal relationships between service convenience dimensions and service performances (service quality and customer satisfaction). The other two hypotheses were on comparisons for the effects of convenience dimensions on service quality and customer satisfaction between department stores and general super markets. To test the hypotheses, three department store chains (Hyundai, Lotte, and Shinsegae department Store) and three general super markets (E-mart, Homeplus, and Lotte mart) were involved. Overall, 510 usable responses were used. The data were analyzed using regression analysis. Results - The results largely support the hypothesized relationships of the proposed model. The results show that access convenience, transaction convenience, benefit convenience, and post-benefit convenience have positive influences on service quality, whereas decision convenience, access convenience, transaction convenience, benefit convenience, and post-benefit convenience have positive effects on customer satisfaction. Furthermore, the results show that there are differences between department stores and general super markets in the effects of benefit convenience and post-benefit convenience on service quality as well as the effects of transaction convenience and post-benefit convenience on customer satisfaction. Conclusions - The concept of service convenience is important in retail environments but little is known about this topic in retail literature. Specially, while service convenience dimensions have different impacts on service performance in distinct retail environments, there has been little investigation or comparison between retail types as regards service convenience. This study is the first to test the differences between distinct retail types (department stores and general super markets) on the service convenience-service performance links. Managerially, the findings of this study suggest that the service convenience management of retailers is an important part of successful service performance management. Because it is most important that both department stores and general super markets enhance benefit convenience to improve service performance, managers of both store types need to invest their resources to reduce consumers' perceived time and effort expenditures to experience the retailer's core benefits. Therefore, the results of this study suggest that retail stores should spend human and financial resources to enhance customer perceptions of service convenience, while also considering what constitutes the service outcome in the consumer's mind. Furthermore, the findings suggest that managers need to use different service convenience management tactics in department stores and general super markets. Specifically, managers in general super markets should pay more attention to benefit convenience and transaction convenience to achieve better service performance whereas managers in department stores should concentrate on post-benefit convenience to create customers' positive evaluation.

"对我们而言, 成为一名负责的公民和一份成功的事业之间没有区别.....他们对今天的沃尔玛是完全一样的." Lee Scott, 沃尔玛的CEO在2005年卡崔琳娜飓风灾难之后(Esty and Winston 2006) Lee Scott的声明标志着可持续发展的一个新的时代. 作为一个被全球生产商和零售商所关注的全世界最大规模的经销商确认了他们的可持续发展的意图. 近十年来, 环保运动不断增长, 并扩展到全世界. 公司已经诞生, 产品已被创造, 学术期刊 已经展开, 政府已经承诺—所有这一切都在追求可持续发展(Peattie and Crane 2005). 虽然进展的确比一些人渴望的慢了一些, 但是很多大规模的经销商已经为环保做出了可持续发展的努力. 为了更好的理解这个运动我们同时提供高管和消费者参与的有包装的消费品产业的角度. 该研究依赖于三个潜在主题: (1)概念和证据表明,公司为很多理由进行可持续发展 (2)在有包装的消费品行业中, 可持续发展活动的数量在持续增长 (3), 因此, 必须探索可持续发展在消费者意识中起的作用. 根据这些主题, 143名大学生和101名企业高管参加了调查来评估一系列的有关可持续发展的变量包括愿意支付, 行为意图, 态度和偏好. 结果显示高层管理者相信可持续发展的三个最主要的原因是(1)盈利能力的机会; (2)以实现对环境的义务; (3)对顾客和股东负责. 大学生的三大原因: (1)对环境的责任; (2)为子孙后代负责, 和(3):一种有效的管理资源. 虽然企业高管和大学生对支持可持续发展的理由不同, 但是企业高管和消费者的报告显示了对剩下大部分的可持续发展问题的相似性. 另外, 当我们要求消费者去评估6个关键问题的重要性时(医疗保健, 经济, 教育, 犯罪, 政府支出, 和环境), 保护环境仅排在第四位(Carlson 2005). 这6个问题都被认为是重要的, 三个最重要的是(1)改善教育;(2)本地区的经济发展,以及(3)卫生保健. 为了可持续发展的持续性, 我们也将预期结果. 反映社会, 企业利益表现的新定义和执行期的延长同样被揭示出来(Ehrenfeld 2005; Hitchcock and Willard 2006). 基于文献我们发现了三个基本范畴的结果:(1)改进组成的满意度, (2)分化的机会, 以及(3)金融奖励. 在每一种分类中, 我们发现从可持续发展活动中导致11种不同结果的几个特定的结果. 我们的调查结果表明,最有可能的结果最高的前五项依序为公司的可持续发展追求的是:(1)绿色的消费者将会更令人满意;(2)公司形象会更好, (3)公司的责任将得到加强, (4)会降低能源成本;(5)产品将会更多的创新. 另外, 为更好的理解消费者的环境 "身份" 和在市场购买中愿意显示出这个 "身份" 的有趣的交集, 我们扩展了以前Experian Research(2008) 的研究. 因此,受访者分为四个不同类型的绿色消费者(行为绿色,想法绿色, 潜在绿色, 或真正褐色)来获得更好的理解绿色消费者. 我们评估这些消费者愿意从事环保行为评估三种选择. (1)购物零售商支持环保措施;(2)支付更多来保护环境, 以及(3)支付更高的税收,政府可以支持环保措施. 想法绿色消费者表示最愿意改变, 紧随其后的是行为绿色消费者, 潜在绿色消费者和褐色消费者. 这些差异都是显著的(p<.01). 结论和启示我们采用描述性研究, 旨在促进我们理解战略领域的可持续性. 确切地说, 该研究以特定的偏好, 意图, 愿意支付, 行为和态度填补了进行比较与对比的持续性的商业管理者和消费者意见的文献的空白, 对从业人员, 能获得一个战略观点. 此外, 许多结果已经说明, 受访者愿意为产品付出更多来保护环境. 其他特定的结果表明, 女性受访者始终比男性强愿意交流, 为这些产品付更多的钱, 在环保的零售商. 了解这些额外的信息, 实践者现在有了更多的特定市场, 对目标和交流他们为可持续发展所做出的努力. 虽然这项研究仅仅是最初的一步了解实践者和消费者对于可持续发展的异同, 我们的结果对实践与研究都有帮助. 未来的研究应向测试其他变量的影响关系, 以及其他特殊行业.

Previous publications regarding the design and specifications of the interface inductor and the DC side capacitor for a STATCOM usually deal with the interface inductor and the DC side capacitor only. They seldom pay attention to the influences of the interface inductor and capacitor on the performance of a STATCOM system. In this paper a detailed analysis of influence of the interface inductor and the DC side capacitor on a STATCOM system and the corresponding design considerations is presented. Phase and amplitude control is considered as the control strategy for the STATCOM. First, a model of a STATCOM system is carried out. Second, through frequency domain methods, such as transfer functions and Bode plots, the influence of the interface inductor and the DC side capacitor on the stability and filtering characteristics of the STATCOM are extensively investigated. Third, according to this analysis, the design considerations based on the phase margin for the interface inductor and the DC side capacitor are discussed, which leads to parameters that are different from those of the traditional design.

The hospital standardized mortality ratio (HSMR) is a widely used generic measure for assessing quality of hospital care in many countries. However, the validity of HSMR as a quality indicator is still controversial. We critically reviewed characteristics of HSMR and suggested how to use HSMR as a quality indicator in the Korean setting. The association between HSMR and other quality measures of hospital care is inconclusive. In addition current HSMR model has shortcomings in risk adjustment because of the lack of clinical data, accuracy of disease coding, coding variation among hospitals, end-of-life care issues, and so on. Therefore, HSMR should be used as an indicator for improvement, not for judgement such as public reporting and pay-for-performance. More efforts will be needed to tackle practical and methodological weaknesses of HSMR in the Korean setting.

A large number of people suffered from traffic accidents each year, so people pay more attention to traffic safety. However, the traditional methods use laser sensors to calculate the vehicle distance at a very high cost. In this paper, we propose a method based on deep learning to calculate the vehicle distance with a monocular camera. Our method is inexpensive and quite convenient to deploy on the mobile platforms. This paper makes two contributions. First, based on Light-Head RCNN, we propose a new vehicle detection framework called Light-Car Detection which can be used on the mobile platforms. Second, the planar homography of projective geometry is used to calculate the distance between the camera and the vehicles ahead. The results show that our detection system achieves 13FPS detection speed and 60.0% mAP on the Adreno 530 GPU of Samsung Galaxy S7, while only requires 7.1MB of storage space. Compared with the methods existed, the proposed method achieves a better performance.

The purpose of this study was to assess elementary student's ability of measuring length, area, and volume and reading metric scales. The findings of this study were as follows. All students were successful in measuring without scale, regardless of grades. But they were less successful in measuring the task using standard and nonstandard scales. Especially, in measuring area, lower grade students were not able to perform the task using nonstandard instruments, but higher grade students were able to perform the task. Measuring area using grade paper was least successful for sixth graders. In measuring volume, students under fifth grade read the upper scale when using graduated cylinder. In measuring by direct comparison, students were more successful in measuring length than in measuring area and volume using given material. The use of given nonstandard material was successful for 4th, 5th, and 6th grade students. In measuring using metric scale, lower grade students did not pay attention to the zero of the scale, but just read the end point. Higher grade students considered both zero and end points.

This study tries to measure the direct and indirect effects of the Regional Strategic Industry (RSI) promotion projects in Chungbuk Province in Korea. In specific, it critically examines whether there exists policy consistency and connectivity between the hardware-oriented Stage I (2002~2007) and the software-centered Stage II (2008~2012) RSI promotion projects. Applying System Dynamics (SD) techniques, this study examines complex system characteristics of RSI promotion projects, all of which have been derived from the causal and stock-flow models and their simulated results. Major findings are as follows: Firstly, 'the continuous investment' is regarded as the most crucial policy leverage for the strategic industry promotion and regional economic growth. Secondly, without exceptions, the RSI promotion projects should switch their evaluation criteria to performance-oriented ones. Thirdly, in selecting their subprojects, the RSI promotion projects should pay due attention to evaluating technology value and marketability. Fourthly, it should put policy priority in strengthening cluster networking and interconnectivity among projects, inevitably supporting a selective number of virtuous network systems. Fifthly, auxiliary projects such as marketing, technology aid, and knowledge-based services should not be overlooked.

The paper is to serve as a guide for deciding on a desirable direction for the vessel buyback program, reviewing their performance and economic effects from fish harvest reduction due to not reaching MSY. Compared with maximum willingness to pay for vessel buyback programs designed to avoid economic losses occurring as a result of overfishing, the portions of investment costs for buyback program are so small comparatively to the range of 0.32% to 12.19% at the annual base. The economic loss effects occurred in terms of the reduction of fishing harvest are comprehensively estimated at the present value of 30,877 billion won since 1971, and exceeded the revenues for fish harvests from 1999. In order to resole fish stocks through a vessel buyback program, this paper recommends that the yield should be reduced to less than the intrinsic growth rate. Otherwise, the buyback program policy eventually fails regardless of the temporal effect of benefits. This paper further argues that technical policy tools such as fishing grounds, fishing seasons, size of fish and minimum size of meshes should be effectively utilized.

Many international transactions involve the use of security devices, commonly referred to as "guarantees", "bonds", or "standby credits", designed to protect one of the parties from a breach by its counter-party. These security mechanisms may be provided by banks, insurance companies, specialized surety companies, or other financial service firms. Although some legal systems distinguish between "guarantees", "bonds", and "indemnities", these terms are often used as synonyms in the everyday language of international traders. It may therefore be necessary to examine the particular characteristics and nature of the guarantee obligation in order to properly classify the guarantee. Two main categories of guarantee are demand and suretyship. Under a demand guarantee, the guarantor must pay on first demand by the beneficiary. The beneficiary only has to demand payment under the guarantee - there is no need to prove that the principal has actually defaulted on a contractual obligation. Under a suretyship or conditional guarantee, the obligation of the guarantor is triggered by the actual default or contractual breach of the principal, as evidenced in a document such as a court judgement or arbitral award against the principal. Guarantees have been widely used in the international business transactions. Main uses of guarantees are as follows : Performance Bonds/Guarantees, Bid(or Tender) Bonds/Guarantees, Advance Payment or Repayment Bonds/Guarantees, Retention Bonds/Guarantees, Maintenance(or Warranty) Bonds/Guarantees etc.
