Purpose: To study, analyze, and investigate how to improve the service quality distribution and perceived value of passenger loyalty in low-cost airlines in Thailand. Research Design, data, and methodology: The data was collected from low-cost airline passengers who had used low-cost airlines within Thailand more than twice in the last 12 months. In total, 632 questionnaires were received, representing 97.32%, and in-depth interviews were done using the semi-structured technique. The key informants were either executives or representatives from 4 low-cost airlines operating in Thailand. We utilized structural modeling techniques to examine the data relevant to the investigation. Results: The results show that low-cost airline passengers in Thailand have strong opinions about the perceived value of the passenger loyalty of low-cost airlines within this sector of the Thai air travel industry. The variables were sorted in order of importance and included passenger loyalty, satisfaction, trust, perceived value, and service quality distribution. The relationship between the service quality distribution variables and the significance in relation to passenger loyalty according to low-cost airlines in Thailand showed that service quality distribution had a positive effect on perceived value and that passenger satisfaction has a direct positive effect on passenger loyalty. Conclusions: The 8 QPSTL strategy is successful in terms of service quality distribution and passenger satisfaction, therefore it is an important aspect of low-cost airlines in Thailand.

The paper demonstrates that versioning of digital products occurs more frequently than that of physical products because of low marginal cost. The versioning occurs no matter what a customer knows his/her reservation price. Low-quality version will not be produced when the difference between reservation prices is very large. The paper also shows that a firm tries to lower the quality of low-quality product to prevent customers with high reservation prices from purchasing low-quality product.

Microbial transglutaminase (MTGase) was investigated to determine whether it was an effective binding agent for the processing of low-quality pork loins. MTGase especially promoted the coagulation of myosin heavy chain (MHC). However, the effect of MTGase on MHC from low-quality meat was less than that from the normal meat when the reaction time was not enough. The breaking strength of the heat-induced gel made of myosin B from low-quality meat with MTGase was lower than that of normal meat. Sausage made with low-quality meat with MTGase did not exhibit improved hardness, as compared to that made with normal meat. Results of this study indicated that use of low-quality meat in the manufacture of sausage was feasible to get textural property equal to that of normal meat sausage, when a half or more of the raw material was normal meat and MTGase was used in the sausage.

Purpose: The purpose of this study was to investigate the relationships between anxiety, depression, low anterior resection syndrome, and quality of life after lower anterior resection for rectal cancer. Methods: The participants of this study were 105 rectal cancer patients who visited the outpatient department of a hospital in Seoul for treatment or follow-up consultations. Data were collected using self-reported questionnaires and clinical records. To measure the variables, the Hospital Anxiety and Depression Scale, Low Anterior Resection Syndrome Score, and Quality of Life Questionnaire-Core 30 were utilized. Data were subsequently analyzed using the SPSS/WIN 20.0 program. Results: Low anterior resection syndrome was more severe among patients whose cancer was located closer to the anus, and had a greater range of resection in those who received neoadjuvant treatment. When anxiety, depression, and low anterior resection syndrome score were higher, quality of life scores were lower. Conclusion: These results suggest that low anterior resection syndrome may negatively impact quality of life. Therefore, it is necessary to provide patients with symptom management support/assistance through evidence-based nursing interventions, and evaluations of low anterior resection syndrome to relieve anxiety and depression, and thus enhance quality of life.

公司生产不同功能, 设计, 颜色的产品. 产品扩散的出现有三个不同的原因. 当存在规模经济, 当这种产品和别的产品一起生产时, 单位成本比单独生产要低. 二, 消费者是异构的, 即它们具有不同的品味, 喜好, 或价格弹性. 一家公司可赚取细分为具有类似特点的不同群体的消费者更多的利润. 例如, 产品扩散通过更准确地满足不同消费者的需要来帮助公司增加利润. 产品扩散的第三个原因是基于战略. 生产一定数量的产品, 不仅可以阻止通过提供给一些少数市场的产品进入, 也使得公司可以有效地应付低价格进入. 通过生产各种产品, 公司可以减少利基, 使潜在进入者有较少进入的诱因. 此外, 企业可以生产新产品来应对进入, 我们称之为战斗品牌. 也就是说, 当一个进入者试图以低廉的价格吸引消费者, 已存在者介绍新的低质量的产品, 同时保持现有产品的价格. 产品扩散的缺点是同型装配. 一些买了高价位的产品的消费者会转向低价位的产品. 此外, 当新产品与对手现有的产品的异化程度不高时, 由于激烈的竞争, 产品扩散会降低利润. 许多研究已经在经济分析和市场营销等领域的产品线竞争的影响. 它们展示了一个垄断者可以通过调整质量来解决市场中的消费者对质量的偏好不同的同型装配的问题. 他们发现, 喜欢高品质的产品的消费者将获得他或她最喜欢的质量, 但没有这方面的偏好的消费者将获得比他或她所喜爱的质量低的产品. 本研究分析了产品的竞争在一个双头垄断市场, 两种不同类型的消费者对质量偏好的影响. 我假设这两家公司将在这个意义上的不对称, 一个运营商可以同时生产高, 低质量的产品, 而一个进入者只能产生低质量的产品. 产品扩散的影响是可以通过比较市场结果来解释, 当已存在的运营商生产两种产品和只生产一种产品时. 在这个案例中, 当已存在的运营商只生产高品质的产品, 由于激烈的竞争, 在喜欢低质量产品的消费群中低质量的产品价格趋于下降. 但由于缺乏竞争, 在喜欢高质量产品的消费群中价格会上涨. 据了解, 当企业在进行价格竞争时, 理想状况是当公司的对 手提高价格时, 此公司也提高价格, 这被称为战略补充. 由于价格是战略性的补充, 我们有两种相反的效果. 事实证明, 一个高品质的产品价格上升, 因为竞争力减弱的积极作用超过了战略互补的负面影响. 这意味着, 已存在的运营商推出了低质量的产品时还需要增加高品质产品的价格. 然而, 在进入者的低质量产品的价格变化是模糊的. 二, 此案例中, 已存在的运营商只生产低品质的产品, 在偏好低质量的消费群中价格往往增加. 但在偏好高质量的消费群中价格往往下降. 低质量产品的价格下降是因为负面影响大于正面影响. 而且, 当已存在的运营商生产两种产品时, 其低质量产品的价格往往较高, 尽管两家的低品质的产品质量一样. 此原因由于对高品质产品价格的负面影响, 运营商没有较大的动机去降低低品质产品的价格. 事实上, 竞争的产品线对利润的影响不仅取决于价格变化, 还取决于销售和同型装配. 如果在边际成本同产品质量的差异相比是适中的话, 产品扩散的积极影响大于负面影响, 从而增加利润. 此外, 如果成本差异是非常大(小), 运营商最好只生产一种低 (高)质量的产品. 而且, 本研究还分析了当公司通过关注战斗品牌来决定产品特征时, 竞争产品线的影响. 最近, 大韩航空和韩亚航空公司建立了廉价航空线路, 分别是Jin线路和釜山线. 来应对Hansung航空和济州航空. 另外, 很多网上书店也进入市场, 例如处于领先地位的实体书店Kyobo已经有了自己的网上书店. 通过战斗品牌, 在它的低品质产品跟新成员比起来有差别时, 一个具有高品质产品的运营商通过生产更多的低质量产品可以增加利润.

This paper investigates how servicescape perception influences customer experience quality in hedonic service settings. In addition to the direct effect of servicescape quality on customer experience quality, the indirect effects of servicescape quality on customer experience quality via employee-to-customer interaction quality and peer-to-peer interaction quality are also investigated. We collected data through a self-administered survey. The proposed relationships were tested using structural equation modeling. The results show that servicescape quality influences customer experience quality both directly and indirectly through employee-to-customer interaction quality and peer-to-peer interaction quality, and customer experience quality influences customer loyalty. Additionally, we find that the indirect path via peer-to-peer interaction quality is significant only in a low-satisfaction customer group. The indirect effect of servicescape quality perception through peer-to-peer interaction quality is significant only in low-satisfaction customer groups. Therefore, if evaluations for this indirect effect fall below an acceptable level, it should be addressed first before improving on other attributes. However, after this point, further improvements offer few if any gains; therefore, service firms should allocate their resources to quality improvements to other factors. This study is the first to investigate the indirect effects of servicescape quality on customer experience quality via peer-to-peer interaction quality in hedonic service settings. Additionally, this study demonstrates that the significance of this indirect effect applies only to a low-satisfaction customer group.

Recent research on quality management systemically explored the use of quality management practices and performance. The consequences of using quality practices have not been consistently confirmed despite an increasing number of published empirical studies. The results of empirical studies of quality practices and performance are mixed. This study examines which quality management practices indicate high-, medium-, and low-performance under the TQM framework using MANOVA and multiple discriminant analysis (MDA). To measure quality management practices, this study used the Malcolm Baldrige National Quality Award (MBNQA) framework. Based on a survey of 490 suppliers from eleven different industries in Korea, the results revealed that the high performing group surpasses the medium and low performing groups in process management, employee empowerment, employee education and training, and employee satisfaction. Furthermore, the high and medium performing groups exceed the low performing group in human resource planning and evaluation, strategic deployment, leadership system, and senior executive leadership.

To evaluate the total quality activities is the most fundamental and critical process as one of the PDCA cycle. The quality award criteria such as Malcolm Baldrige National Quality Award and Deming Award can be a, pp.ied to the guideline for evaluating quality activities. We can identify several important factors for TQM by referring quality award criteria, but they don't suggest how efficiently implement TQM. In this paper, two methodologies are a, pp.ied to evaluate the TQM activities comparatively. One of them is the traditional scoring system (TSS) by analytic hierarchy process (AHP). TSS is the system which evaluates the performance of TQM by the weighted sum of critical success factors. Several quality award system are typical examples of TSS. The other is the efficiency measuring system (EMS) by data envelop analysis (DEA). DEA outperformed other alternative methods to measure the efficiency and it can be a, pp.ied to evaluate the TQM activities. The evaluation system by DEA can be named as EMS. The objective of this paper is to suggest a model called TAE (Total quality management Activities Evaluation), for evaluating TQM activities. In this model TQM organizations are classified into four types by considering TSS and EMS. Those types are high weighted sum and high efficiency type, high weighted sum and low efficiency type, low weighted sum and high efficiency type, and low weighted sum and low efficiency type. Therefore TQM organizations must not only make efforts to get the higher scores in terms of TSS, but also take necessary steps to enhance their efficiencies.

CCTV has been known to possess high level of objectivity and utility. Hence, the government has recently focused on replacing low quality CCTV with higher quality ones or even by adding high resolution CCTV. However, converting all existing low-quality CCTV to high quality can be extremely costly. Furthermore, low quality videos prior to CCTV replacement are likely to be of poor quality and thus not utilized correctly. In order to solve these problems, this paper proposes a method to improve videos quality of images using SRGAN(Super Resolution Generative Advisory Networks). Through experiments, we have proven that it is possible to improve low quality CCTV videos clearly. For this experiment, a total of 4 types of CCTV videos were used and 10,000 images were sampled from each type. Those images could then be used for machine learning. The fact that the pre-process for machine learning has been done manually and the long time that required for machine learning seems to be complementary.
