KakaoTalk has become a reputed mobile social network and an inseparable part of people's lives by leading the mobile industry in South Korea. However, there is a lack of studies in academia regarding perception of the consumers and assessment toward the mobile marketing and services by KakaoTalk. Based on the theoretical orientation of Elaboration Likelihood Model (ELM: Petty & Cacioppo, 1986) and electronic service quality (E-S-QUAL: Parasuraman, Zeithaml, & Malhotra, 2005), this study investigates the effects of information sources (Charles & Richard, 1988), and examines the consumer perception toward the service quality of KakaoTalk. A total of 209 responses were collected, using a self-administered survey in Seoul and Gyeonggi province, South Korea from March 2015 to June 2015. A seven-point Likert scale survey was developed to measure the information sources (i.e., argument quality, post popularity, and post attractiveness), electronic service quality (i.e., efficiency, fulfillment, privacy, and system availability), attitude (i.e., usefulness, preference, and overall attitude), and behavioral intention (i.e., like intention, share intention, and purchase intention). This study reveals a consensus that an online environment is different from the traditional retail context in terms of information source and service quality. Specifically, the results indicate that argument quality greatly impacts the attitudes of the individuals and their behavioral intention toward mobile shopping via social media channel. The most powerful factor among E-S-QUAL is "efficiency." This dimension of service quality influences the customer perception of usefulness and preference as well as share and like intention toward mobile shopping on KakaoTalk.

As the Internet connections and services at U.S. public libraries have increased dramatically since 1990s, defining, assessing and measuring quality of these new electronic services have become a critical issue. This research was a study designed to identify key dimensions of Internet service quality at public libraries by providing a systematic framework for measuring and assessing the quality of Internet services. The study used modified SERVQUAL and SERVPERF instruments which have been widely used service quality measurement in business marketing areas and LibQUAL+ model which are widely adopted service quality measurement instrument in most of the academic libraries in U.S.

The purpose of this study is to classify the quality attributes of service quality for the elderly in public libraries, derive satisfaction coefficients and dissatisfaction coefficients, and present the priority improvement of service quality. To this end, a survey was organized with 22 questions from LibQUAL+ for elderly users who use library in uiseong-gun, gyeongsangbuk-do. Quality factors for service were classified into three areas of LibQUAL+ based on the kano model, and the satisfaction index and dissatisfaction index felt by users for each service quality were calculated through timko's customer satisfaction coefficient. Based on this, a Potential Customer Satisfaction Improvement index (PCSI index) was obtained to determine how much user satisfaction can be improved when actual requirements are met. As a result of classification of quality attributes of service quality, it was classified into 9 attractive quality, 7 one-dimensional quality, 1 indifference quality, and 5 must-be quality. In the improvement ranking for service, the first place was 'making electronic resources accessible from my home or office', the second place was 'print and/or electronic journal collections I require for my work' and the third place was 'a library web site enabling me to locate information on my'. It is expected that the study results can be used to present quality factors that should be managed and improved first when providing services for the elderly.

This paper aims to study on the relationship of u-Security service, usefulness and citizen satisfaction. Independence variable is u-Security service, a mediation parameter is usefulness, and dependent variable is citizen satisfaction. Using SPSS 18.0, a series of factor analysis, reliability analysis, multiple regression analysis and path analysis have been performed. The conclusion is as following. First, u-Security service affects usefulness. That is, as publicity safety, system quality, service quality increase, usefulness increases. Second, u-Security service affects citizen satisfaction. That is, as publicity safety, system quality, service quality increase, citizen satisfaction increases. Third, usefulness affects citizen satisfaction. That is, as economic usefulness and security usefulness increase, citizen satisfaction increases. Last, u-Security service has direct and indirect effect in usefulness and citizen satisfaction. That is, usefulness is an important variable that mediates u-Security service and citizen satisfaction.

Purpose - Through the analysis of the characteristics of overseas direct purchase websites and the relevant empirical analysis of the quality of service delivery, the activated theory/strategy and significance of the overseas direct purchase are sorted out. Research design, data, and methodology - In the process, to make more effective analysis, several analysis tools and analysis programmes are used, IBM SPSS Statistics 23.0 and IBM SPSS AMOS 23.0. Results - Among the characteristics of the overseas direct purchase website, the security, convenience and information provided by the overseas direct purchase have already had a positive impact on the satisfaction. The quality of the delivery service is composed of four factors: rapidity, reliability, intimacy and correctness. The research results indicate that the satisfaction level has a positive impact on the re-purchase intention. Conclusions - The significance of this study has the characteristics of overseas direct purchase sites which have confirmed that security convenience and intelligence availability have a positive impact on satisfaction and re-purchase intent. It is important to have a safe and reliable access to shopping sites on overseas direct purchase sites. In the characteristics of overseas direct purchase sites, the interaction have no positive effect on satisfaction and re-purchase intention.

In order to provide various types of application services based on the Internet, it is ideal to guarantee the quality of service(QoS) for each flow. However, realizing these ideas is not an easy task.. It is effective to classify multiple flows having the same or similar service quality requirements into same group, and to provide service quality for each group. The queue management mechanism in the router plays a very important role in order to efficiently transmit data and to support differentiated quality of service for each service. In order to efficiently support various multimedia services, an intelligent and adaptive queue management mechanism is required. This paper proposes an intelligent queue management mechanism based on deep reinforcement learning that decides whether to deliver packets for each group based on the traffic information of each flow group flowing in for a certain period of time and the current network state information.

As internet services are being provided through a wireless access, the importance of quality of experience (QoE) is stressed that is defined as the quality that indicates user's actual feeling when a service is provided. Unlike quality of service (QoS) that can be expressed as a numerical value, it is difficult to represent QoE in an objective way. If an internet service is serviced over a wireless channel, its QoE can be affected by a number of factors such as fading, mobility and so on. This paper, therefore, attempts to specify the relationship between QoE and QoS by conducting practical measurements for the voice service through 3G high speed packet access (HSPA) access network. Analysing the measured results, it has been shown that received signal strength indicator (RSSI) has a great influence on mean opinion score (MOS) through transmission delay.
