Fingerprint image quality checking is one of the most important issues in on-line fingerprint recognition because the recognition performance is largely affected by the quality of fingerprint images. In the past, many related fingerprint quality checking methods have typically considered the local quality of fingerprint. However, It is necessary to estimate the global quality of fingerprint to judge whether the fingerprint can be used or not in on-line recognition systems. Therefore, in this paper, we propose both local and global-based methods to calculate the fingerprint quality. Local fingerprint quality checking algorithm considers both the condition of the input fingerprints and orientation estimation errors. The 2D gradients of the fingerprint images were first separated into two sets of 1D gradients. Then，the shapes of the PDFs(Probability Density Functions) of these gradients were measured in order to determine fingerprint quality. And global fingerprint quality checking method uses neural network to estimate the global fingerprint quality based on local quality values. We also analyze the matching performance using FVC2002 database. Experimental results showed that proposed quality check method has better matching performance than NFIQ(NIST Fingerprint Image Quality) method.

This paper examines the effect of the producer-supplier quality contract parameters and the magnitude of the quality related variables on the quality of the final products. Our analysis focuses on the parties' equilibrium behavior In a quality game environment where the supplier should choose among the two production technologies, one requiring high cost but producing high quality Parts and the other requiring low cost but producing low quality parts and where the producer should decide whether to do the inspection of the parts. The game framework is employed to depict the potential conflicts existing between the Producer and the supplier because the Producer can not observe the supplier's choice and each party wants the other to bear the cost of producing high quality products. In our model, we specifically consider the competitive situation where the producer competes with a firm producing the same product. We employ the market share attraction model to Incorporate the competitive situation and completely characterize the equilibrium by using the Nash equilibrium concept for the game solution. Our results show that the equilibrium depends on the contract terms and the magnitude of the quality related variables. Compared to the non-competitive situation, the probability of producer's Inspection and the probability of supplier's choosing the high quality technology increases in a competitive situation. This is true even when the competitor's quality is lower than the producer's lowest. As a result, the quality of the final product increases In a competitive situation. And as the failure cost borne by the supplier increases, the probability of choosing the high quality technology Increases and the probability of inspection decreases. The net effect of this results in the decrease of the final product quality.

Purpose - The purpose of this study is to classify the quality factors of chicken restaurant customers with the service quality based on the SERVQUAL, the quality factors based on the selection attributes and service qualities of chicken restaurants used in the previous studies. Research design, data, and methodology - This survey was carried out on the students of Kangwon University in Samchuk City, Kangwon Province from November 20 - November 30, 2017, and a total of 260 questionnaires were distributed, with 222 collected. Of them, effective questionnaires applied in the final study were a total of 193 except 29 that couldn't be used. Results - The findings of this study are as follows: Firstly, chicken restaurants' quality factors were divided into seven categories like cleanliness, service encounter quality, product quality, aesthetics, overall interior, purchase quality, and convenience. Secondly, it showed that service encounter quality, purchase quality, and cleanliness had a positive impact on customer satisfaction, respectively. Thirdly, it showed that service encounter quality, purchase quality, and cleanliness had a positive impact on trust, respectively. Fourthly, it showed that customer satisfaction had a positive impact on behavioral intention. Additionally, it suggested that customer satisfaction of chicken restaurant consumers had a positive impact on behavioral intention and thereby, higher customer satisfaction leads to higher levels of reuse and recommendation intention. Lastly, after checking the effect relations of trust between customer satisfaction about chicken restaurant and behavioral intention, it was analyzed that customer satisfaction has a positive impact on trust and trust has a positive impact on behavioral intention. On the other hand, it showed that trust have a partially mediating effect in the relations between customer satisfaction and behavioral intention. But, it showed that product quality, aesthetics, overall interior, purchase quality, and convenience did not have a positive impact on customer satisfaction. Conclusions - Chicken restaurant consumers put more priority on friendly and good services of chicken restaurant staff in service encounter and delivery order, rather than on reasonable price and discount systems. Thereby, chicken restaurant marketers need to take factors like service encounter quality, cleanliness into more consideration.

Purpose: The concept of quality is changing in the quality 4.0 era with the fourth industrial revolution in the world. This research aims to understand the characteristics of well-adapted companies against the quality 4.0 era and to improve the quality of clothing companies. Methods: We analyzed companies that responded well to the quality 4.0 era, especially Kutesmart using Quality 4.0 Matrix. We focused on the service process of Kutesmart and we suggested modified service process to improve quality. We also interviewed an expert to verify this process is valid. Results: We found that two types are classified of well-adapted companies against the quality 4.0 era. Especially, Kutesmart has built a smart factory and introduced new technologies like 3D scanner and big data analysis. However, Kutesmart has a weakness in post-purchase process like other clothing companies. Kutesmart could solve this problem with modular production method for damaged part of customer. Conclusion: This research can be used for better understanding of the characteristics of well-adapted companies against the quality 4.0 era and service process of Kutesmart that is custom clothing company for providing information for benchmarking in this industry. This study suggests that further empirical researches on the costs and the efficiencies of applying the new technologies are necessary.

Ginseng is an international herb that has been used for thousands of years. Two species most commonly applied and investigated in the ginseng family are Asian ginseng and American ginseng. The number of randomized controlled clinical trials (RCTs) has conspicuously increased, driven by the rapid development of ginseng. However, the reporting of RCT items of ginseng is deficient because of different trial designs and reporting formats, which is a challenge for researchers who are looking for the data with high quality and reliability. Thus, this study focused on providing an extensive analysis of these two species and examined the quality of the RCTs, based on the Consolidated Standards of Reporting Trials (CONSORT) guideline. Ninety-one RCTs conducted from 1980 to 2019 that were related to Asian ginseng and American ginseng used singly met our inclusion criteria. We found that the reporting quality of the two species has improved during the past 40 years. Publication date and sample size were significantly associated with the reporting quality. Rigorous RCTs designed for the species of ginseng are warranted, which can shed light on product research and development of ginseng in the future.
