Given that smartphone-based social network services (SNS), such as KakaoStory is now being widely used as a way for people to connect and communicate with each other, this study examines key factors leading to the continued use of SNS. People have been using PC-based SNS, such as Cyworld, for years are now using smartphone-based SNS, such as KakaoStory. KakaoStory developed by KakaoTalk has rapidly grown up as the largest smartphone-based SNS in Korea as smartphone penetration increases. It is more difficult for firms to maintain their current users over time in that alternative SNSs satisfying people's new needs are constantly emerging and evolving. In this sense, one of the most challenging issues for SNS firms is how to retain their current users in the long run. However, there are few empirical studies on this issue. Applying the IS continuance model proposed by Bhattacherjee [2001], this study explores key determinants of users' smartphone-based SNS continuance intention. The model suggests that perceived usefulness and user satisfaction are the key determinants of IS continuance intention. However, the model includes only the utilitarian value that users can obtain through the use of smartphone-based SNS, by considering perceived usefulness. Therefore, the study attempts to extend the IS continuance model by considering hedonic and social values simultaneously. More specifically, we consider subjective norms as social value that are proposed by the theory of reasoned action and the theory of planned behavior. We also consider perceived enjoyment as hedonic value that is emphasized as a key factor influencing users' behavior intention and actual behavior, particularly in the context of hedonic IS use. By considering the three values in our model simultaneously, we could offer a deeper understanding of smartphone-based SNS continuance. That is, this study could offer an explanation of how each value is associated with user satisfaction and SNS continuance intention. The customer value-satisfaction-loyalty model can strengthen the assertion that smartphone-based SNS continuance intention is determined by various different types of customer values, such as utilitarian, hedonic, and social ones. Moreover, the model provides a theoretical basis for the assertion that customer values lead to increased loyalty via customer satisfaction. In this regard, we theorize that SNS continuance intention is influenced by users' various values, namely perceived usefulness, perceived enjoyment, and subjective norms, via user satisfaction. To test the proposed research model and hypotheses, we conducted a partial least squares analysis using a total of 253 data collected on the users of smartphone-based SNS (i.e., KakaoStory). The key findings are as follows: First, it has been found that SNS continuance intention considerably depends on user satisfaction. Second, user satisfaction is determined by confirmation, perceived usefulness, and perceived enjoyment. Third, concerning the effects of the three values on SNS continuance intention, only perceived enjoyment regarded as hedonic value was statistically significant. That is, perceived usefulness considered as utilitarian value and subjective norms considered as social value had no effect on SNS continuance intention. Finally, our results indicate that confirmation increases perceived usefulness, perceived enjoyment, and user satisfaction. The results reconfirm the effectiveness of IS continuance model in predicting smartphone-based SNS continuance intention. Moreover, the results demonstrate that perceived enjoyment reflecting hedonic value is the most important predictor of SNS continuance intention. Therefore, it is imperative for firms to meet SNS users' hedonic value to retain them in the long run. Meanwhile, we could not find any empirical evidence to support the assertion that subjective norms are associated with user satisfaction and SNS continuance intention. The results lead us to conclude that when users have enough direct experience in SNS use, subjective norms have no effect on SNS continuance intention. Discussions and implications of the results are provided.

A BPO is an irrevocable undertaking given by an Obligor Bank acting on behalf of the buyer to a Recipient Bank acting on behalf of the seller to pay on satisfaction of certain specified conditions. There have been a Trade Service Utility(TSU), a Transaction Matching Application(TMA) and ISO 20022 TSMT messages that core electronic technical systems linked to the BPO. As a key usefulness of the BPO, it brings to market an alternative means of satisfying the risk mitigation, financing and information management needs of banks and businesses engaged in trade. That is, corporates can spread the risk among multiple Obligor Banks by requesting multiple BPOs for the same trade transaction not to exceed the value of the initial transaction. Since the BPO replaces the manual document checking process with the electronic matching of data, buyers and sellers will benefit from significantly increased accuracy and objectivity. By using BPO, buyers and sellers can become trusted counterparties by demonstrating reliability and giving sellers the assurance of being paid on time as per the payment terms and conditions agreed. When compared to L/C, the BPO requires submission of data only. This requires a change of practice of those accustomed to dealing with physical documentation. The beneficiary of a BPO is the Recipient Bank which is always the Seller's Bank. In the meantime, banks will need to agree between themselves that the URBPO 750 will be applied, modified or excluded. However, customers of banks will face low transactional costs due to a fully automated process and standardized data formats used in international trade documentation. There is no amendment and cancellation rules in the URBPO 750s, but only have Assignment of Proceeds rules. As a result, the BPO is likely to enable new business opportunities, lower costs, fast transaction process and strengthen key customer relationships.

The change towards meeting diverse customer needs has started to affect the hotel industry as well. Design hotels emerged as customers demanded differentiated lodging experiences they could not fulfill at franchise hotels which were uniform in style everywhere in the world. Design hotels are meant to provide a new concept of space through unique design sensibility and work of designers, which highlighted the role of interior design. This research analyzes the characteristics of indoor space expressed in design hotel common spaces by the French designer Andree Putman, also known as the founder of boutique hotels and the concept of design hotels. As the original founder of the concept of design hotels, Putman's scope of work stretches wide, from interior design to product design. She is also one of the few French designers with a modernist inclination. The research runs a review on previous literature, characteristics of design hotels according to design tendency, and the association with characteristics of indoor space designed by Andree Putman, followed by case analyses extracted by analyses on design characteristics of common spaces she has designed. The analysis reveals that she creates comfortable yet elegant space, using contrast and fusion arising from negotiation of design styles to interpret space, the sense of spatial balance and understated expression of order through symmetrical structures, diverse creation of space through geometric structuring, highlighting indoor space by utilizing lights as objects, and the heterogeneous harmony achieved by contrasting juxtaposition, and understated formativeness. It is expected that study results would be utilized as methods of new designs of interior space in design hotels.

Recently, YouTube's growth started drawing attention. YouTube is not only a content-consumption channel but also provides a space for consumers to express their intention. Consumers share their opinions on YouTube through comments. The study focuses on the text of global entrepreneurs' speeches and the comments in response to those speeches on YouTube. A content analysis was conducted for each speech and comment using the text mining software Leximancer. We analyzed the theme of each entrepreneurial speech and derived topics related to the propensity and characteristics of individual entrepreneurs. In the comments, we found the theme of money, work and need to be common regardless of the content of each speech. Talking into account the different lengths of text, we additionally performed a Prominence Index analysis. We derived time, future, better, best, change, life, business, and need as common keywords for speech contents and viewer comments. Users who watched an entrepreneur's speech on YouTube responded equally to the topics of life, time, future, customer needs, and positive change.

Business model innovation creates differentiated value to customers by transforming various elements of doing business. Rather than focusing singularly on either the external or internal environment, the business model innovation aims to identify the optimal combination of internal resources, competence, and the external factors, such as customer's needs and new opportunity. However, due to lack of clear definition of business model innovation, and inability to generate company's core business model, business model innovation has been difficult for companies to lead next growth. This paper reviews existing definitions of business model innovation and explore existing types of business model innovation and timing of business model innovation through two case studies. Concept of business model innovation which we identify, is composed of value proposition, value creation through value chains and networks, and profit model innovation. Finally, we demonstrates that already successful businesses can also create new values through business model innovation and adaptive advantage, even in a rapidly changing market environment.

The manufacturing system has been changed from labored manual process system, which is managed and operated by managers and operators, to CIMS(Computer Integrated Manufacturing System) for integration of manufacturing, research, development and consumption in the age of diverse customer's needs[6]. However, because it involves the hierarchical system composed of many sub-systems interface and its installation & setup cost is very expensive, CIMS has many difficulties in constructing the durable optimal system that is able to adapt to rapid in-outer circumstance change. So, HMS(Holonic Manufacturing System), the new conceptual manufacturing system having the self-problem-solving and self-organization[11], is instructed to solve these difficulties that it has in these days. The system flexibility in the HMS is able to be ensured, with the integration of human's strong points into mechatronics manufacturing system to reduce interference among sub-systems. In this paper, the manufacturing process rationalization and integration of the assembly line in an automobile industry, has lots of problems in efficiency and productivity, has been studied in an early stage of converting the present state of process system to HMS, which is human-oriented processing system, to improve the line efficiency, system productivity and reliability by using human capability effectively. This paper is derived into the human-oriented & object-oriented holons settlement of the shop floor system composed of processing, assembly and material handling system for the future holonic manufacturing system, which is going to be computer supported control system.

As a micro computer or micro processor technology has been advanced, the essential part which consists of electric power system has been changed into intelligent electronic device(IED), that is one kind of embedded system. There are already many parts changed into digital from analog in control and maintenance devices of electric system. These trends make advanced and novel concepts of devices and systems, that we couldn't even imagine in the analog circumstances. Now, the rate's of change is comparatively slower than IT field that is mainly represented by mobile communication, but that is a big change in the history of electric industries. Some people in those field called it Power-IT, and there have been many kinds of researches. Accelerated systems to go digital, users always and continuously demand more convenient, practical, and new functions. So, a lot of electric system manufactures have had tasks realizing many kinds of functions in an electronic device. According to the high-end technologies in semi-conductor and micro-computer field, manufactures can fully satisfy almost all of customer's needs, but there are other kinds of problems, such as large amount of program code, increasing complexity in proportion with program amount, and the hardness of maintenance and revision of the program. So nowadays, the necessity of embedded OS was emerged as a solution, and many researchers and manufactures have concentrated on studies related to embedded OS and its application.

In the outwardly changing environment of public security these days, police administration faces the nation's request for qualitative improvement of police service and the new request of police reformation for changing function of police in Korea. The nation wishes police to provide service fairly. The issue most seriously mentioned in the reliability of police service is very large gap in the recognition of service quality between supplier and consumer. To get the trust of nation in delivering police service, the police must have justness, consistency, punctuality of delivery, propriety and efficiency. However, the recognition of citizen, the consumer of police service is more important. How to correspond to the nation's request to police needs to be decided by evaluating the quality of present police service. It is necessary to be interested in what customer wants so as to evaluate the quality of police activity.

The emergence of the luxury market has led numerous academic researchers, as well as marketers in the luxury market, to pay attention to both identifying luxury brand features and measuring perceptions toward luxury brands. Especially, Korea is a significant emerging market for luxury goods. Young consumers and male consumers are getting into the luxury market fast and these new segments will keep increasing. There are only a few studies related to distinctive definitions of luxury brands and measurement development for the Korean market. However, there are some limitations in these previous studies in that they did not capture the nature of luxury due to their inappropriate of subjects and approach in data collection and to lack of a perspective of Korean specific features. Thus, the purpose of this research is to identify Korean consumers' perceptions toward luxury products and, ultimately, to develop a reliable and valid measurement items for the luxury products' features for the Korean market. Defining the three high constructs(functional, emotional, and symbolic aspects) as a key needs and benefits on luxury brands, we looked at four stages of development for generating and deducting items by luxury industry experts and luxury consumers, as well as for testing measures by 20th~60th consumers. As a result, this study confirmed that luxury brands consists of high quality, high price, unique design, and luxury store; the emotional aspect construct combines craftsmanship, VIP service, and high social status; and the symbolic construct includes brand heritage and being a well-known brand. Finally, 22 measurement items (Measures of Luxury Brand for Korea: LBK) were developed for the conceptual features for luxury brands from a Korean perspective. This study provided understanding of Korean consumers' perceptions toward luxury brands from an academic perspective. For the managerial implication of this study, LBK can be utilized to judge both luxury brands and mass brands, to diagnose current a brand's luxuriousness, from the customer's point-of-view, and, finally, to measure a Key Performance Index (KPI) of luxury brand companies.
