The global mobile Internet service market is growing very rapidly, shooing drastic increases in its sales volume. Despite this growth of the market, it has not yet reached its full-grown stage, and this calls for a study on the service preference based on the characteristics of the users. As most of the existing studies in this area have centered on its technical features, they fall short of providing to the related companies any useful data to which they can practically refer in developing the future mobile services that suit for various user needs, and making plans to increase the sales volume. Based on these circumstances, this study is to investigate how the mobile contents preference is differed in accordance with the user characteristics of the Korean and Chinese mobile Internet service users. This study is also to analyze how the relationship between the user characteristics and the preferred mobile contents types is moderated by nations, Korea and Chinese. To accomplish these research purposes, this study developed a set of research model and hypotheses based on a comprehensive review of the related studies. To prove the research hypotheses, this study conducted a survey among the Korean and Chinese nubile Internet service users and performed a variety of analyses of the data collected including the questionnaires, using the SAS version 9.

The purpose of this paper is to propose and test a conceptual framework that investigates the effects of perceived service quality on customer satisfaction, attitude toward brand(Ab) and customer loyalty. To test the framework, structural equation modeling are applied to data collected from 210 samples in mobile phone service industry. The results of this research indicated that interaction quality and outcome quality of perceived service quality are positively on customer satisfaction, but the outcome quality is stronger influence than interaction quality. The findings also show that outcome quality effect on directly Ab and then interaction quality effect on indirectly Ab through customer satisfaction. But There are no effect outcome quality, interaction quality and Ab on customer loyalty without customer satisfaction effect. These results include implications that mobile phone service company should have customer satisfaction to retain customer and customer loyalty.

The diffusion of new technology has traditionally focused on the adoption perspective. Researchers refer this use-diffusion paradigm to behaviors of use after adoption. This study intends to analyse the influential factors of use-diffusion and continual use of website and applications in medical service. To achieve this a use-diffusion model as a conceptual frame work is suggested. Medical information quality, personal innovativeness and subjective norm are assumed as antecedent variables medical website and application's rate of use, variety of use, and continued use intention as result variables. According to the empirical study results medical information quality, web based application usability, personal innovativeness, and subjective norm have a meaningful influence on medical service consumer's use-diffusion patterns. Also pattern of use influences the continued use intention. This study provides an opportunity to understand medical service consumer's behavior after website and application use adoption and suggests further directions for establishing medical service online marketing strategy by determining influential factors of use-diffusion and continued use of medical online marketing tools.

The integration of products and services is being expanded in both manufacturing and service companies such as in Apple's iPod & iTunes, Amazon's Kindle, and Hyundai Motor Company's Mozen. This phenomenon has recently accelerated due to multiple factors including market change, lessening of differences in quality of products or services, the paradigm of participation and sharing, and deindustrialization and evolution toward becoming a service economy. The objective of this paper is to investigate and analyze the status and characteristics of integration of products and services in Korean firms and to suggest policy directions promoting this integration. Towards this purpose, income statements from the Korea Listed Companies Association (KLCA) database of companies listed on the Korea Stock Exchange are analyzed regarding the servitization of manufacturing firms as well as the productization of service firms. In addition, this research investigates the Korean Innovation Survey 2011 database for the service sector and 2010 database for the manufacturing sector in order to evaluate R&D activity in each. In the manufacturing sector, the average ratio of service sales (servitization) was low at 0.208, with bias in the level and distribution of ratios associated with the manufacturing sector. 18 out of a total of 23 sectors (78%) have low servitization, showing there's a long way to go for servitization in the Korean manufacturing sector. In the service sector, the average ratio of product sales (productization) was 9.53%, which is relatively high compared to that of the manufacturing sector. However, the distribution of ratios is also biased, as with the manufacturing sector. Based on this analysis, policy directions are proposed in terms of 1) R&D, 2) concept boost, 3) R&D result spread, 4) statistics, 5) infrastructure and 6) green growth.

This study aims to provide basic resources for the construction of the archives on the official family service history in Korea. The study collected records of family policies and official family service from 1948 to 2019 and thereafter attempted to classify the official family service. In addition, experts were consulted to diagnose compliance with research contents and directions, investigate priorities of the family policies, and provide opinions on the elements of each process of archiving. The results of this study were as follows. First, there were five areas of concern to be considered in the process of establishing an archive of official family services: concept, scope, collection, arrangement, preservation, and utilization. Second, the findings suggest which processes are critical to developing a sustainable and systematic archive system for the official family service history. The construction of the archives will provide a platform for understanding the contents of integrated family policies and inform the direction of future family policies in Korea. In addition, these archives will be an important factor in building a solid Korean national identity.

The purpose of this study is to clarify the background of the controversial attempt to establish a new public medical school linked to compulsory service as a means of strengthening public healthcare in Korea, and to raise anticipated problems with possible solutions. In Korea, healthcare is predominantly provided by the private sector focused on medical care, rather than public healthcare, even under the national health insurance system. The government has been mainly in charge of public health and unmet medical services from a residual perspective, but health inequalities still exist. To resolve this issue, the government created the concept of public health and medical service (PHMS) from a universal perspective and tried to strengthen the infrastructure of public healthcare and to foster core PHMS doctors by establishing a new public medical school linked to compulsory service in medically vulnerable areas. This study investigated the reality and concept of the new public medical school planned by the government, and identified problems such as the possibility of obtaining accreditation and evaluation before its establishment, the side effects of dividing doctors' roles, the waste of huge amounts of resources, and insensitive policies. In conclusion, in order to resolve health inequalities in Korea, we need to train doctors through medical school education that strengthens the social responsibility of doctors along with strengthening public healthcare infrastructure, and to provide a better environment for doctors working in medically vulnerable areas through sophisticated policies.

The airline industry faces with significant competition due to the rise of technology innovation and diversified customer needs. Therefore, continuous quality management is essential to gain competitive advantages. For this reason, there have been various studies to measure and manage service quality using customer reviews. However, previous studies have focused on measuring customer satisfaction only, neglecting systematic management between customer expectations and perception based on customer reviews. In response, this study suggests a framework to identify relevant criteria for service quality management, measure the importance, and assess the customer perception based on customer reviews. Machine learning techniques, topic models, and sentiment analysis are used for this study. This study can be used as an important strategic tool for evaluating service quality by identifying important factors for airline customer satisfaction while presenting a framework for identifying each airline's current service level.

This study exploratoryly examines the effect of time poverty experienced by tourists on the quality of tourism due to the recent rapid change in the tourism service system. Due to various reasons, the process of consuming considerable time and energy of the mind along with anxiety, tension, and anxiety caused by the sense of time poverty experienced by tourists occurs. As a result, time poverty comes and the quality of tourism decreases. On the other hand, the factor of trust in the change of the tourism service system is also an important axis for satisfaction, but if a problem occurs in efficiency related to time, satisfaction with the tourism service may decrease. From this point of view, this study conducted a literature review focusing on the fact that time poverty due to changes in the tourism service system reduces the satisfaction of tourists and even affects the quality of tourism. Through this, various implications were provided for the government's policy to support workers' leave.
