The Korean mobile service market has persistently grown with the number of subscribers and volume of mobile traffic. It shows the slow diffusion of 5G subscribers, and rapid growth of both the MVNO(Mobile Virtual Network Operator) market and unlocked mobile phones. Therefore, this study derives the direction of telcos' strategies and policy implications by empirically analyzing the usage and attitude of LTE and 5G subscribers. Our major findings are as follows: First, our current mobile service subscription market constitutes most long-term customers for their incumbent carriers only by device change from lock-in with bundle services. Mobile tariffs, data speed, and benefits of bundle services are important factors affecting choices and customers' satisfaction with a provider and intentions of churning to another. Second, demand and satisfaction for using 5G are less because speeds and service tariffs act as pain points for 5G services. Third, the users' high preferences for MVNOs and unlocked mobile phones are linked to their subscription to MVNOs' low-cost plans with unlocked mobile phones on online channels. These streams lead to a big change in the market competition that MNO(Mobile Network Operator)s' market shares are expected to decrease and MVNOs' shares will be increased by two times, in the near future. Therefore, MNOs need to change their distribution strategies from offline to online channels and try to resolve the stereotype, "mobile tariffs are expensive," by enhancing their service values. Finally, as consumers prefer one-stop service in the same channel regardless of the distribution channel, policies should focus on the consumers' needs for convenience rather than on the channel separation for perfectly unlocked mobile phones.

This study aims to shed light on the new insights on the cross-buying intentions in the banking industry and suggests an integrated model of the cross-buying intentions. Recently with globalization in the financial sector, financial companies are trying to retain current customers and attract new one by developing various financial products. In South Korea, this trend is especially apparent in the banking sector. Cross-selling of various financial products such as beneficiary certificates, bankasurance and etc. is becoming more important in retaining competitive advantage in Korean banking industry. However, there are few studies which are trying to find out the factors affecting cross-buying intentions and explain their interrelationships comprehensively. Based upon the previous studies, this study finds out the factors affecting cross-buying intentions and classifies them into two dimensions: affective and instrumental. Affective dimension includes trust, satisfaction and commitment. Instrumental dimension includes the factors such as geological convenience, one-stop convenience, professionality, and direct mail. The results from this study are as follow. All the factors in the affective dimension(trust, satisfaction and commitment) have significant impacts on cross-buying intentions. Also all the factors in the instrumental dimension(geological convenience, one-stop convenience, professionality, and DM) significantly affect cross-buying intentions. Some implications of this dissertation are as follow; First, this study identifies the antecedents of cross-buying intentions comprehensively. Second, this paper provides practical guidelines for the banks attempting to intensify cross-selling activities. Third, banks need to develop sophisticated plans which can consolidate the emotional ties with customers through positive service experiences as the affective dimension is important in influencing cross-buying intentions. Finally, regarding the instrumental dimesnion, the implications are: 1) Developing various new financial products in addition to traditional product such as deposits and installment savings for improving customer convenience, 2) Enhancing the professionality of employees by strengthening education programs on numbers of financial products, 3) Increasing cross-buying intentions through the DM.

The world is changing drastically by digital information technology and ubiquitous networking. Meanwhile, with the demographic avalanche, South Korea officially became an 'ultra-aging society' in 2026. Simultaneously, this demographic change will also stimulate a cultural climate which facilitates the formation and dissemination of 'slow culture' from the existent urban 'fast culture' which has been weakening the retirement living. One of the fundamental connections with the slow movement appears in the cooking and dining area. With this point of view, this study aims to identify the needs and behaviors of the elderly in current restaurants and a digitally planned multi-purpose one for the future. Small group workshop was employed for this study. In order to elicit detailed information from the elderly group members, scenarios were developed. A group facilitator kept the discussion on track by asking a series of open-ended questions meant to stimulate discussion. As the results, it was revealed that the elderly were interested in digitally planned restaurant which provides one-stop service including entertainment activities, health related contents and socializing with family. Even though this study took restaurant scenarios, the ideas in them also provide holistic perspectives on the direction of marketing and planning strategies on various future environments and services.

A high peak power demand at substations will result under Moving Block Signalling (MBS) when a dense queue of trains begins to start from a complete stop at the same time in an electrified railway system. This may cause the power supply interruption and in turn affect the train service substantially. In a recent study, measures of Starting Time Delay (STD) and Acceleration Rate Limit (ARL) are the possible approaches to reduce the peak power demand on the supply system under MBS. Nevertheless, there is no well-defined relationship between the two measures and peak power demand reduction (PDR). In order to attain a lower peak demand at substations on different traffic conditions and system requirements, an expert system is one of the possible approaches to procure the appropriate use of peak demand reduction measures ...

The export/import processing systems of the foreign advanced port use the integrated database to increase the productivity of the users involved in the port and logistics activities. However all the port and logistics related organizations in Korea such as container terminal, customs, ministry of maritime affairs and fisheries, etc. are using their own databases, so it is very inconvenient to the users to process their export/import affairs. It is necessary to develop the integrated database for the port and logistics affairs to provide the one stop service to the port and logistics related users. So we have investigated and analyzed the databases of port and logistics related organizations, and recognized the users' various needs of information. And then we have suggested the conceptual architecture of integrated database for port and logistics, and proposed the strategies for successful development of the integrated database in this paper.
