Due to the dramatic increase in consumers' price sensitivity and growing importance for global retailers to create relevant price strategies, this study investigates the global pricing strategy of the main SPA brands such as ZARA, H&M and UNIQLO. Based on price information shown on official website, the study developed SPA brand index by using exchange rates in terms of US dollars and ratio of differences between the local price and the US price. These figures were compared with GDP per person data in order to analyze each brand's price level against the income level. The study also compared SPA brand index with Big Mac index to identify the difference in price levels between the fast fashion market and the fast food market. ZARA and H&M were mostly targeting Middle East and Asia as a high-price market when considering index only. After taking the income level into account, however, Asia came out be the highest price market and Middle East was similar to the US market. On the other hand, UNIQLO targeted Asia as the lowest price market and the US and EU as the highest in terms of index only. But, Asia came out to be the highest price zone after considering the income level while the price of the US and EU was reasonable. Comparison with Big Mac Index indicated that most of Asia had a higher price level of the fashion market than the food market, whereas most European countries had a similar or high-price level of food market.

The purpose of this study is ti find out a desirable way to stability and improvement of household economy by studying the changes of consumption level and consumption pattern of urban salary and wage earners' households during the years from 1970 to 1978. For this study, "Annual Report on the Family Income and Expenditure survey" (Published by the Bureau of Statistics, Economics Planning Board) has been used as basic material, and the methods of analysis used here are the time series analysis. We have gained the results as follows: 1) From 1970 to 198, the total income level increased at the rate of 416.2% in nominal price, but only 74.4% in reql price, while the total expenditure level showed 338.5% increase in nominal price, but its real increased proved only 418.2% in consideration of inflation. APC decreased from 95.1%(in 1970) to 80.7%(in 1978). 2) As for the expenditure pattern for the above mentioned nine years, the rate of food expenditure increased until 1975 under the price influence, but it trended to decease there after on . The rate of housing expenditure showed a gradual increase while that of fuel and light expenditure was on the decrease. The rate of clothing expenditure had been on the decease until 1974 but it began to increase gradually thereafter on. The trend of miscellaneous expenditures was irregularly up and down, educational expences being the first rank among them, Non-living expenditure had been constant until 1974 but it decreased a little after that. From the results it was found that the consumption level of the salary and wage earners' household in all cities from 1970 to 1978 was not practically improved because of rise in prices, nor was the Engel's coefficient and the rate of miscellaneous expenditure changed distinctively. However, as the successive decrease of APC suggests the possibility of economic development, we must try to put stress on economy in consumption and on encouraging. This will help run our household economy in safety and stability.

This study aims to investigate the factors influencing donation intention when the option to donate is presented during a purchase decision. Through an experimental design, we examined how price differences and reference group effects impact donation intention. We created stimuli with three price difference conditions (high, low, and control) and two levels of referent power (high and low), and involved 480 Korean consumer panels in the experiments. After controlling for psychological reactance levels, a two-way MANCOVA confirmed the main effects of price difference and referent power but found no interaction effect between these variables. Notably, consumers were less likely to feel guilty for not selecting the donation option when its price was slightly higher than that of the non-donation option, compared to the scenario where the prices were the same. Additionally, consumers exposed to high referent power experienced greater irritation, guilt, and shame if they did not choose the donation option compared to the low referent power group. Multiple regression results showed that guilt significantly influenced the intention to purchase a donation option, whereas irritation and shame did not. These findings suggest that understanding situational factors such as price differences and referent power can help develop effective marketing strategies and encourage voluntary participation in donations.

This study was intended to examine the effect of consumer materialism, price and point-of-purchase advertisements on consumer preference and purchasing intention with respect to discount jeans. Information for the study was obtained through the use of an experimental design which was 2$\times$[2$\times$3] mixed factorial design. The subjects were two hundred and seventy college male and female students. The data were analysed with factor analysis, ANOVA by using the SAS program. The main results were as follows: First, the results indicated that the 3-way interaction effects among materialism, price and point-of-purchase advertisements on consumer preference. Second, the results showed the 2-way interaction effects between materialism and price between materialism and price on consumers’purchasing behavior. These results indicated that materialism have not direct effect on consumers’purchasing behavior but significant influence under those condition in which price effect occurs. And different from other point-of-purchase advertisements, power words’advertisements show negative effects on consumer preference in case of low price jeans, having no connection with materialism level.

This study examined: 1) the effect of store density on perceived crowding 2) the difference of perceived price benefit of sale by store density 3) the effect of perceived price benefit and store density on perceived crowding and 4) the effect of perceived crowding and price benefit on shopping behaviors. Store density and perceived crowding were categorized into social and spatial dimensions. Data were collected with 6 (high, medium, and low social and spatial densities) * 2 (sale and no-sale) between-subjects experimental designs. A total of 395 responses were analyzed. The results revealed that social density affected social crowding, but spatial density had no effect on perceived crowding. Price benefit of sale was not different by store density. The sale itself did not affect perceived crowding. Under the social density situation, perceived price benefit reduced spatial crowding and social crowding showed a positive effect on purchase behavior while spatial crowding had a negative effect. However, the most important effect on purchase behavior was price benefit. The study implies that social density (not spatial density) is important for consumer behavior and retail strategies.

We compared empirically the forecast accuracies of the LSTM model, and the ARIMA model. ARIMA model used auto.arima function. Data used in the model is 100 days. We compared with the forecast results for 50 days. We collected the stock closing prices of the top 4 companies by market capitalization in Korea such as "Samsung Electronics", and "LG Energy", "SK Hynix", "Samsung Bio". The collection period is from June 17, 2022, to January 20, 2023. The paired t-test is used to compare the accuracy of forecasts by the two methods because conditions are same. The null hypothesis that the accuracy of the two methods for the four stock closing prices were the same were rejected at the significance level of 5%. Graphs and boxplots confirmed the results of the hypothesis tests. The accuracies of ARIMA are higher than those of LSTM for four cases. For closing stock price of Samsung Electronics, the mean difference of error between ARIMA and LSTM is -370.11, which is 0.618% of the average of the closing stock price. For closing stock price of LG Energy, the mean difference is -4143.298 which is 0.809% of the average of the closing stock price. For closing stock price of SK Hynix, the mean difference is -830.7269 which is 1.00% of the average of the closing stock price. For closing stock price of Samsung Bio, the mean difference is -4143.298 which is 0.809% of the average of the closing stock price. The auto.arima function was used to find the ARIMA model, but other methods are worth considering in future studies. And more efforts are needed to find parameters that provide an optimal model in LSTM.

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.

Inertial Navigation System(INS) has been used in the field of air navigation for a long time but is not popular in general aviation due to high price. Recently low-price GPS is available but vulnerable to radio interference. As an alternative on these problems, GPS/INS integrated navigation system has been considered. GPS/INS is capable of implementing navigation with low-price inertial sensors but its accuracy is dependent upon how much drift of INS may be calibrated by using GPS. In order to apply GPS/INS to air navigation, it must be investigated how long drift of INS in case of no GPS aiding will be bounded within requirements for safe flight. From the above motivation, the flight test for GPS/INS navigation system was conducted in order to make sense its performance in air navigation and its result was shown.
