The purpose of this study is to analyze the characteristic of quality attributes of smart hotels by using a SERVQUAL-IPA model, focusing on Chinese, which has the most proactive approach for the adoption of smart hotel system. Toward this goal, six quality factors—tangibles, reliability, assurance, responsiveness, empathy, and playfulness—were extracted through factor analysis, and IPA was used to appraise the degree of importance and satisfaction for each quality attribute. As a result of the SERVQUAL-IPA model, quality attributes were categorized into four groups of 'keep up the good work,' 'possible overkill,' 'low priority,' and 'concentrate here.'. Furthermore, it was concluded that there is a need to focus on the following elements: ‘smart devices can assist customers in emergency situations’, ‘when the room control system identifies customer needs, the staff can provide prompt service’, ‘development and improvement of mobile applications that enable customers to control room amenities’, ‘regular maintenance for smart devices’, and ‘providing data-driven personalized recommendations through customer activity data analysis’.

In this study, based on previous research on personal broadcasting, we indirectly measured content quality, YouTuber attributes, user satisfaction, and behavioral intention, which are latent variables that cannot be directly measured, as measurement variables, and then measured theoretically between the latent variables. In order to analyze the causal relationship, we used a structural equation model to determine to what extent the content quality of the YouTube mukbang channel and the YouTuber's attributes influence behavioral intentions such as purchase, recommendation, and continued use according to viewers' satisfaction with use. We intend to analyze and verify the relationship between related variables. The research results are as follows. First, the value, relevance, timeliness, completeness, and data quantity of content quality were found to have no significant impact on user satisfaction. Second, the trustworthiness, expertise, attractiveness, and intimacy of YouTuber attributes were found to have a significant impact on user satisfaction, but the similarity of YouTuber attributes did not have a significant impact on usage. Third, user satisfaction was found to have a significant impact on behavioral intentions and purchase intentions. However, user satisfaction was not found to have a direct significant impact on recommendation intentions or continued usage intentions.

본 연구는 감마선 및 전자선 조사에 의한 닭고기 원료 사료 내에 존재하는 주요 위해 미생물을 비열처리 살균 효과를 검증하기 위하여 진행되었다. 일반세균, E. coli 및 Salmonella의 위해 미생물을 분쇄 닭고기 원료사료에 접종 후 3, 5, 7, 10 kGy의 전자선과 감마선으로 조사하였다. 전자선과 감마선 모두 3 kGy의 조사 시 시험된 미생물을 검출 한계 이하로 사멸시켜 분쇄 육류 원료 사료의 경우 3 kGy의 흡수선량이 충분한 비열 살균 조건임을 보여주었다. 방사선 조사에 의한 원료 사료의 품질 지표 변화를 알아보기 위하여 분쇄 닭고기의 조사 처리 후 pH 변화, 색도 측정, 전자코 이취 분석을 수행하였다. pH와 색도의 경우 감마선 및 전자선 조사에 의해 유의미하게 변화하지 않는 것으로 나타났다. 전자코 이취 시험의 경우 감마선 조사의 경우 3 kGy의 저선량 조사부터 이취가 발생되기 시작하였으며 10 kGy 조사 시 급격하게 이취의 정도가 증가하는 것으로 나타났다. 전자선 조사 역시 3 kGy의 조사부터 이취가 발생하였으며 5 kGy의 선량 이후 흡수선량이 증가함에 따라 이취가 점진적으로 증가하였다. 본 연구 결과 3 kGy의 저선량에서도 닭고기를 원료로한 펫푸드의 비열 살균 효과를 충분하게 이루어짐을 확인하였고 품질 지표에도 부정적인 영향을 주지 않는 것으로 나타났다. 이러한 비열처리 펫푸드의 살균 기술 개발은 국내 펫푸드 시장의 활성화와 반려 동물의 복지 향상에 기여할 것으로 기대된다.

Since the appearance of smartphones, the smartphone market has been in fierce completion by new technologies and marketing trends. The smartphone market is now somewhat saturated, and the manufacturers are trying to improve their position in the market through the repurchase of existing customers and the influx of competitors. At the same time, customers have their own purchasing criteria for smartphones. Therefore, manufacturers need to determine new technology and marketing trends based on customer purchasing trends and usage characteristics. The aim of this study is to analyze the quality attributes of smartphones. We conducted a survey on 220 respondents, and divided the respondents into several groups by purchasing trends and usage characteristic through cluster analysis. The groups are analyzed and compared based on the Kano model for the quality attributes of smartphone. The analysis result are as follows. Firstly, purchasing trends divide responders into groups that prefers high-end premium smartphones and those that take into account practicality in terms of purchasing trends. Secondly, usage characteristic divide responders into three groups: those with clear usage pattern, those who prefer ease of use, and the rest, and we find out that those with clear usage pattern are important customer in viral marketing. Lastly, Kano analysis is revealed the ‘Slow/ hi-speed camera’, ‘Private mode’, ‘Widget’, ‘Health care’ are attractive quality attributes.

This study examined the service quality attributes of the CVS (Convenient Store) packed meal products by applying the Kano model. The main survey was conducted by a research company using an online survey in the form of a selfadministered questionnaire. The 499 samples were limited to customers who had experienced CVS packed meal products within the last months. A total of 14 service quality attributes of the CVS premium packed meal products were categorized as four attractive qualities, one must-be quality, three one-dimensional qualities and six indifferent qualities. According to the Better and Worse quotient designed by Timko, ‘coupon and sales promotion event’, ‘healthy menu configuration’, and ‘balanced nutrition’ had higher levels of the Better coefficient. On the other hand, ‘hygiene and cleanliness’, ‘the delicious food’, and ‘fresh ingredients’ showed a higher Worse coefficient. The results also suggest that each service quality attribute is not a single dimension but a complex attribute. As a result, this research suggests that marketing practitioners should immediately identify consumer’s changing perception of quality to attract new customers and prevent existing customers from leaving in the CVS premium packed meal products segment.

The aim of this study was to investigate the effect of pretreatments on quality of frozen peach. Pretreatments including steam blanching, water blanching, high pressure, and osmotic dehydration were applied to two varieties (Daeokgye and Hwangdo). Pretreated peaches were frozen and thawed at -20oC and 5oC, respectively. Steam blanching and osmotic dehydration with ascorbic acid reduced ΔE values without change of pH and acidity. Osmotic dehydration with sucrose decreased drip loss and increased brix. Freezing/thawing resulted in an increase of maximum force, while maximum force decreased with increasing time of steam and water blanching. Furthermore, osmotic dehydration with calcium chloride increased maximum force. High pressure decreased maximum force of Daeokgye and increased that of Hwangdo compared with non-treatment. Total polyphenol content, DPPH radical scavenging activity, and ABTS radical scavenging activity were improved by pretreatment including steam blanching, blanching, and osmotic dehydration with ascorbic acid.

For several decades, attribute classification methods using the asymmetrical relationship between an attribute performance and the satisfaction of that attribute have been explored by numerous researchers. In particular, the Kano model, which classifies quality attributes into 5 elements using simple questionnaire and two-dimensional evaluation table, has gained popularity: Attractive, One-dimensional, Must-be, Indifferent, and Reverse quality. As Kano's model is well accepted, many literatures have introduced categorization methods using the Kano's evaluation table at attribute level. However, they applied different terminologies and classification criteria and this causes confusion and misunderstanding. Therefore, a criterion for quality classification at attribute level is necessary. This study is aimed to suggest a new attribute classification method that sub-categorizes quality attributes using 5-point ordinal point and Kano's two-dimensional evaluation table through an extensive literature review. For this, the current study examines the intrinsic and extrinsic problems of the well-recognized Kano model that have been used for measuring customer satisfaction of products and services. For empirical study, the author conducted a comparative study between the results of Kano's model and the proposed method for an e-learning case (33 attributes). Results show that the proposed method is better in terms of ease of use and understanding of kano's results and this result will contribute to the further development of the attractive quality theory that enables to understand both the customers explicit and implicit needs.
