典型的价格促销是指降低一定数量产品的价格或以相同的价 格获得更多数量的产品, 从而增加价值和创造经济的激励购买. 价格促销经常用来鼓励没有消费过产品或服务的用户试用产品或服务. 因此, 理解价格促销对那些从来没有使用过促销品牌的消费者的此品牌质量认知的影响是很重要的. 然而, 如果消费者通过价格促销获得的产品的质量不好, 促销可能达不到用经济的刺激方法来增加销售的效果. 相反则有可能发生. 具体来说, 通过价格促销消费者产生低的质量的认知会削弱经济的和心理上的激励, 减少购买的可能性. 因此, 对市场营销人员来说理解品牌的价格促销信息如何影响消费者对此品牌的质量的不良认知是非常重要的. 先前的有关价格促销对质量认知的影响的研究有不一致的解释. 一些是关注价格促销对消费者认知的不利影响. 但是其他的研究显示价格促销并没有提高消费者对品牌的不良认知. 之前的研究发现这些不一致的结果和价格促销曝光的时机以及相关的试验得出的质量评估有关. 而且, 消费者是否经历过产品促销都可能会调节这些影响. 一些研究把产品类别的不同作为基本的因素. 本研究的目的是探讨在不同的情况下, 价格促销信息对消费者的不良的质量认知产生的影响. 作者控制了促销曝光的时机, 过去的各种促销形式以及信息发布的方式. 与以往的研究不同, 作者通过控制以前个人使用此产品的经验的潜在调节作用来测试事先设定限制的价格促销的影响. 这样的操作可以解决相关的有可能产生的争议. 这种方法对实际工作方面也是有意义的. 价格促销不仅适用于已存在的目标消费者, 而且可以鼓励没有使用过产品和服务的消费者尝试此产品或服务. 因此, 对市场营销人员来说理解品牌的价格促销信息如何影响消费者对此品牌的质量的不良认知是非常重要的. 如果没有使用过这个品牌的消费者通过价格促销获得的产品的质量不好, 促销可能达不到用经济的刺激方法来增加销售的效果. 相反则有可能发生. 另外, 如果价格促销结束, 购买了这个产品的消费者可能会出现明显的减少再购买行为. 通过文献回顾, 假设1用来探讨消费者通过过去的价格促销获得的质量认知的调节作用. 消费者对没有使用过的品牌的价格促销而产生的质量认知的影响会被此品牌过去的价格促销活动所调节. 换句话说, 消费者会对没有进行过价格促销的没有使用过的品牌产生不良的质量认知. 假设2-1:未使用过的品牌进行首次价格促销的时候, 价格促销的信息发布的方式将影响价格促销的成败. 假设2-2:消费者越不在意价格促销的原因, 越容易对产品的质量产生不良的认知. 通过测试1, 简要地解释了产品和品牌在提供四种价格促销形式之前并解释说明了每种价格促销形式. WAVEX这个虚拟品牌的质量的认知被评估为7. 网球拍被选中的原因是由于选定的产品组必须过去几乎没有价格促销活动来消除促销的平均次数对价格促销信息的影响, 正如Raghubir和Corfman(1999)所提出的. 测试2也用网球拍作为产品组, 主持测试2的管理者与测试1相同. 随着测试1, 选择了对产品组熟悉而对产品不熟悉的受访者. 每个受访者被分配到代表WAVEX价格促销的两种不同信息发布方式的两组中的一组. 在评估WAVEX的质量认知为7以前, 受访者看了每个促销信息. 不熟悉的实验品牌的价格促销对消费者的质量认知的影响被证明为会被以前有过或没有价格促销活动所调节. 与过去的促销行为一致是使品牌评估变得更糟的不良影响的重要变量. 如果此品牌从未进行过价格促销, 价格促销活动会对消费者的质量认知产生不良的影响. 第二, 不熟悉的品牌进行首次价格促销时, 促销信息的发布方式会影响公司促销的成败. 当消费者进行性格归因和情境归因的比较时, 质量认知的不良影响会更大. 与先前主要关注具有或不具有情境/性格归因中良好或不良的动机的研究不同, 本研究的焦点是检验如果公司提出了具有说服性的理由, 即使消费者在价格促销行为中有性格归因, 情境归因也可以被推断出的事实. 这种方法, 在学术方面取得了很大的成果, 意义在于它运用非数学的问题来解释固定和调整过程而不像以前的研究大部分是把它用于数学问题来解释. 换句话说, 根据基本属性错误, 有很大的倾向去性格地归因其他的行为. 当这种情况出现在价格促销时, 我们可以推断出消费者很有可能性格地归因公司的价格促销行为. 反而, 即使在这种情况下, 公司可以调整消费者的锚定性来降低性格归因的可能性. 另外, 不像多数对价格促销的长/短期影响的以往的研究, 只考虑价格促销对消费者的购买行为影响, 本 研究测试对质量认知的影响, 一个影响消费者购买行为的因素. 这些结果在实际工作方面有重要启示. 本研究的结果可以作为新产品有效的提供促销信息的指南. 如果品牌要避免错误的暗示, 比如在施行价格促销战略时被认为是产品的质量不好, 一定要为促销提供清晰合理的理由. 尤其是对那些以前没有进行过价格促销活动的公司来说, 提供明确的理由尤其重要. 不一致的行为可以导致消费者的不信任和焦虑. 这也是无止境的价格战的风险的重要因素之一. 没有事先通知的价格促销会使消费者怀疑, 但不会影响市场份额.

Software process (SP) authentication is a certification system designed in order to improve software process and ensure software reliability of the Korean small and medium enterprises (SMEs). It is composed of 3 grades, 17 evaluation items and 70 detailed evaluation items (software process). In order to certificate grade 2, 42 detailed evaluation items must be satisfied. In order to certificate grade 3, all 70 detailed evaluation items must be satisfied. SMEs are more vulnerable to manpower and material resources than the major company. Therefore, it is difficult for SMEs to invest in the long term to improve the software process. If we can provide the core evaluation items to SMEs, SMEs will be able to improve software quality more efficiently and effectively. It can be used as a short way to acquire SP authentication. The evaluation items of SP are defined as influencing each other. Therefore, the core evaluation items might be established using related techniques. Although we searched for previous researches and related informations, the associated study was insufficient. In this study, ANP (Analytic Network Process) technique was applied, and the core evaluation items of SP authentication were established. SMEs will be able to acquire SP authentication more easily using the core evaluation items. Finally, we expect that this study will be used as a basis material for creating the SP 2.0 version.

Crushed sand is made by crushing the rocks artificially. With a wide shortage of natural river sand all over the region in Korea, demand for crushed sand are becoming increased. However, Informations as to crushed sand are insufficient. In this paper, the actual conditions of crushed sand related to producing and quality variation are investigated. 29 manufacturing company of crushed sand are reviewed. According to results, density of most crushed sand tested exceeded 2.5g/cm3, and absorption ratio meet the requirement of KS except one sample. For grain properties, passing amount of 0.08mm sieve satisfied the requirement of KS except one sample. Grain distribution of most crushed sand is estimated $54.26\%$. But 6 crushed sand sample did not meet the requirement of KS. Fineness modulus and grading are varied from manufacturing region. 18 samples of crushed sand among 29 samples deviated the minimum level of standard grading range by KS. Therefore, improvement of grain properties of crushed sand is urgently needed to manufacture better crushed sand.

In the advance of computer technology, it is possible to keep all the related informations for monitoring equipments in control and huge amount of real time manufacturing data in a data base. Thus, the statistical analysis of large data sets with hundreds of thousands observations and hundred of independent variables whose some of values are missing at many observations is needed even though it is a formidable computational task. A tree structured approach to classification is capable of screening important independent variables and their interactions. In a Six Sigma project handling large amount of manufacturing data, one of the goals is to screen vital few variables among trivial many variables. In this paper we have reviewed and summarized CART, C4.5 and CHAID algorithms and proposed a simple method of screening vital few variables by selecting common variables screened by all the three algorithms. Also how to develop a logistics regression model on a large data set is discussed and illustrated through a large finance data set collected by a credit bureau for th purpose of predicting the bankruptcy of the company.

Handling the manufacured goods is the most cost-consuming task in material handling system in wooden furniture industries. Fully automated warehouse for cartoned goods of a furniture manufacturing company was analized to provide plant engineers and managers with some important informations on the utility and profitability of the automated storage and retrieval system(AS/RS). Process-oriented simulation modeling tech-niques were used to describe the system and to propose some alternatives to promote the efficiency of AS/RS. Simulation report could be inter-preted as follows: 1. Warehouse for the furniture goods must be designed in accordance with reliable material handling program and constructed with suitable equipments depending on the specification of packed products. 2. An excess of palletized products induced the indigestion and the inefficiency of AS/RS of the furniture industry and put this high-costly system into the shade. 3. Overcrowded AS/RS of the furniture factories could regain its material handling function by cutting down the deposit of products into the automated warehouse. For this purpose, reducing the regular output and direct delivering the outside products to the destination should be considered as the definite counterplan. And additional operation of conventional handy warehouse was also expected to improve the efficiency of main AS/RS.
