The use of AI chatbots in frontline customer service is beneficial as it can provide quick service responses, cost-saving on human employees and accelerate customers’ decision-making process. However, implementing chatbots can be a double-edged sword. On the one hand, companies benefit from the use of chatbots. On the other hand, it may hurt customer experience as customers perceive chatbots are less trustworthy and show less social presence. Service failures today have become more unpredictable with the increasing complexity of social environments. Aligning with the trends of online customer service, customers are most likely to encounter a chatbot when seeking online customer service to solve service failures. With most of the previous literature investigating customers’ perceptions of chatbots and chatbot-related service failures, little research has focused on the area where chatbots as service recovery agents and how customers perceive the use of chatbots handling their service requests after service failures.

This study compares and analyzes changes in users’ perceptions of industrial catering food service quality before and after COVID-19. The survey enrolled 226 subjects at five industrial catering establishments in Seoul and Gyeonggi Province; a total of 204 customers with complete data were included in the final analysis. Factor analysis was conducted to verify convergence validity and construct reliability; results pertaining to ‘service and environmental hygiene’ and ‘quality of food’ were extracted. Among the general variables of food service quality, differences were obtained in the user’s perceptions of food service qualities according to gender, education, and marital status. Our results revealed that women, low education, and married people perceived significant differences in all attributes before and after COVID-19. Additionally, varied altered perceptions were determined for service quality according to the occupations of the subjects. However, no differences were obtained for pleasant dining environment in the ‘service and environmental hygiene factor’ and variety of desserts in the ‘food quality factor’.

본 연구의 목적은 국내 레스토랑 이용객의 서비스 실패 후 감정변화에 영향을 미치는 실패 귀인 요소, 그리고 고객의 브랜드 관계 품질이 서비스 실패 귀인 지각에 대한 환원효과를 검증하는 것이다. 본 연구의 시사점으로는 귀인이론은 귀인이론과 귀인적 이론으로 구분할 수 있는데 한 모형에서 귀인이론에 영향을 미치는 개인 신념과 귀인 후의 감정반응 간의 영향관계를 통합적으로 측정하는 연구는 미미하다. 신념(BRQ: Brand Relationship Quality)-귀인-감정 3단계 모형을 구축하고 충돌 감정 반응(분노 VS동정)의 독립성을 같이 검증되었다. 먼저, 감성적BRQ(친밀감 및 사랑)은 통제가능성 귀인에 미치는 환원효과가 있는데 행동적BRQ(상호의존)은 통제가능성 귀인에 미치는 확대효과가 있는 것으로 나타났다. 관리적 관점에서 레스토랑 관리자는 고객의 서비스 실패의 반복 발생 가능성 지각을 낮추고 고객의 동정을 환기해야 한다. 통합적으로 레스토랑 관리자는 고객의 서비스 실패 귀인 지각을 잘 조절하고 고객의 BRQ이 감정반응에게의 영향효과를 환원시켜야 한다. 여러 가지의 서비스 회복 방안을 수립하고 귀 인을 잘 조절해야 한다. 뿐만 아니라, BRQ은 각각 분노 및 동정에 다른 효과(확대VS환충)가 있기 때문 에 고객 BRQ의 특성에 따라 다른 서비스 실패 회복 방안을 제시해야 한다. 예를 들면, 이성적 BRQ 고객에게 금전 보상이나 공정성 거래, 친밀감 및 사랑 고객에게 감정배려, 상호의존 고객에게 호혜성 설득 등 방안을 상황에 맞게 개발해야 한다. 본 연구는 서비스 실패 후 귀인의 매개효과를 탐색적으로 검증하 였는데 BRQ-귀인-감정 과정에서의 여러 가지 조절요인을 고려하지 않는 한계점이 있다. 따라서 추후의 연구에서 서비스 실패 강도의 조절효과를 고려해야 하고 더 완전한 모형을 구축해야 한다.

This study aims to configure what dimensions make up for smart phone after service quality, and how this service quality affects customer satisfaction and customer loyalty. Smart phone market is a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry. To survive in this matured market, companies should have to respond actively to radical changes and customers needs in the so-called Smart Revolution environment. Lately, however, the smart phone market is prospected to move from growth phase to mature phase by the scholars. In order to proactively respond to the change in such market condition, companies need to provide absolute advantage in customer loyalty over their competitors by revolutionizing the after-sales service quality. Qualified A/S will lead to service satisfaction and achieve customer loyalty. The empirical analysis results obtained through A/S quality are as follows : First, human quality (attitude, expertise, problem-solvability), environment quality (handling agility, convenience, comfort), service policy quality (quality guarantee, additional service operation) are dimensions that make up for A/S quality. Second, A/S quality dimension showed a significant positive influence on service satisfaction and A/S satisfaction showed a positive influence on customer loyalty as well. Based on this empirical study, we propose some implications for A/S quality improvement. First, human quality dimension has relatively higher influence on A/S satisfaction in case of free A/S, so companies need to solve the product problem completely when consumer’s first visit by continual employee education. Second, in case of paid A/S, the service policy quality-especially A/S Warranty period- has higher influence on A/S satisfaction.

Mobile phone market, a market of the device leading the digital convergence as well as positioning itself as one of the national growth driving industry and as a daily necessity, is led globally by companies that have been actively responding to changes in the so-called Smart Revolution environment. Lately, however, the Smart Phone market is prospected to move from growth phase to mature phase by the scholars. In order for a company to proactively respond to the change in such market condition, it is imperative that they ensure absolute advantage in customer loyalty over their competitors by revolutionising the after-sales service(A/S) quality that will lead to service satisfaction. This study aims to configure what dimensions make up for mobile phone A/S quality, and how this quality affects customer satisfaction and loyalty as well as proposing directions for A/S quality improvement by identifying them case by case to see what dimensions have more impact on customer satisfaction.

In this work, on-site corrosion behavior of heat resistant tubes of T91, used as components of a superheater in a power plant for up to 25,762 h, has been investigated using scanning electron microscopy(SEM), energy dispersive X-ray spectroscopy (EDS), and electron backscattered diffraction(EBSD), with the objectives of studying the composition, phase distribution, and evolution during service. A multi-layer structure of oxide scale was found on both the steamside and the fireside of the tube surface; the phase distribution was in the order of hematite/magnetite/spinel from the outer to the inner matrix on the steamside, and in the order of slag/magnetite/spinel from the outer to the inner matrix on the fireside. The magnetite layer was found to be rich in pores and cracks. The absence of a hematite layer on the fireside was considered to be due to the low oxygen partial pressure in the corrosion environment. The thicknesses of the hematite and of the slag-deposit layer were found to exhibit no significant change with the increase of the service time.

This paper is to study the missionary reflection of social service mission in Korea church after the 1945 liberation of Korea. When reflecting social service of Korea churches according to the historical features, it could be divided as before and after the 1945 liberation of Korea. The social service before the liberation could be summed up as ‘un-structural service period’ that had been conducted to Korean people in poverty, diseases and ignorance during the beginning of mission by the missionaries. The other could be summarized as ‘structural service period’ that is recognized the ideological conflict and the suffering from the division of Korea into north and south and the Korean war and ‘holistic service period’ that tried to avoid a crisis into social service mission as Korea churches in quantitative growth were experiencing stagnation. The mission before the l945 liberation was an education and a medical service as the approaching method in Korean society. But those services were one method for evangelism because they were based on conservatism theology of early missionaries. So, there was no missio-theological reflection for the extension of God’s Kingdom that Jesus Christ proclaimed in the world. Therefore early Korean churches are ‘un-structural service period’ that emphasizes only individual's spiritual salvation in the absence of society. During the Japanese colonial period social service of Korea church was ‘solidarity period’ that tried to find a clue of national problem solution from a rural community movement. Korean churches in the 1920s began to recognize social salvation and the world’s structural problems. The rural community movement also developed actively for about 10 years from the 1920s to the mid of 1930s, but it should be stopped due to the oppression in and out of church in the late 1930s. Even though there were many believers who died of dire persecution, many main religious associations in Korea found the way to live in sympathy with the visit of Japan’s shrine. After the 1945 liberation Koreans experienced both the joy of liberation from Japan and fratricidal war. In this period the duty of Korea churches was to save Clients in want and received financial support from the western churches because of economical poverty and impoverishment. And the April 19 pro-democracy movement in 1960 was happened due to the political corruption, but the democratization retreated because of the May 16 military coup in 1961. Industrialization and urbanization are promoted as focusing on the economic development, and UIM that helps the human rights abuses of workers origins. In this period Korean churches begin to open their eyes about the evil of social structure and illegality and corruption stemming from the huge gap forming between the rich and the poor, materialism and the negligence of humanity. So this is ‘structural service period,’ for Korean churches that are focusing on the individual’s spiritual salvation become to recognize the evil of social structure and injustice as mission work. Finally, since Korean churches after the 1970s are interested in the church’s growth and expansion, they are not into social service. The economic growth by the military regime caused trouble such as the gap between the rich and the poor, environmental disruption and materialism and formed urban slums. And also Korean churches that disregard these problems are contaminated by growth-oriented theology, but they surprisingly growed with the military regime. In this period the large scale gathering and revival are lively held, and churches closely cooperate in turning the concern about human rights and democratization into individual’s spirit salvation and blessing. As a result, Korean churches after the 1990s have been put aside in the society and stagnated constantly. Now Korean churches stand in between temptation of growth and responsibility of social service. The early Korean churches created the way to mission through social service building up many hospitals and schools as a method of evangelism. Therefore, Korean churches should revive a tradition of holistic mission with both evangelism and social responsibility.

The development of mobile communication technology is transforming the market of mobile communication devices, which is used to be merely for simple communication, into the one which offers features of personal digital assistant (PDA), fax communica- tion and Internet access. Unlike a mobile phone which comes out as a complete package and whose functions cannot be changed, a smart phone can be upgraded by its user, adding or removing apps as he pleases. OS’s of smart phones are iOS-based Apple, Google Android, Window Mobile, and others. Due to its convenience and powerful features, many people use smart phones its high price. On the other hand, consumer complaints are rising on poor A/S for occasional malfunction. This study analyzes how A/S cases can be classified into groups according to quality factors. We evaluate factors such as consumer impression and consumer satisfaction. By dual quality evaluation using KANO method, we would like to show the different A/S strategy for smart phones, compared with mobile phones.
