Purpose - This paper examines how the consumer animosity of partner country influences the purchase of foreign products. We analyzed news sentiment to determine whether Chinese consumer's animosity affect the purchase of the products made in Korea around the time when the U.S. Terminal High Altitude Area Defense missile system was deployed in South Korea. Design/methodology - To measure the tone of Chinese consumer animosity more carefully, we utilized a text mining technique of the Chinese language to read the public's opinion. Using Chinese news paper's editorials of 2015.1-2018.10, we analyzed the sentiment toward Korea and regressed it with Korean export to China. Findings - Empirical results report that Chinese consumers tended to reduce their purchase of consumer goods from Korea when the animosity increased, that is, the sentiments of Chinese news editorials were negative. In contrast, the animosity did not affect the purchase of Korean intermediates or raw materials. We further analyzed the effect by dividing the animosity into three categories; politics, economics, and culture. Among these groups, political news exhibits a unique effect on Chinese purchase on consumer goods from Korea. Originality/value - Existing literature on animosity models has measured the animosity by collecting the consumers' opinions through survey at a given time point, whereas it is measured by analyzing the tone of the press release by sentiment analysis during the time period around the event occurrence in this study.

To boost the IPTV industry, it has being considered to provide terminal portability from one service provider to another for users. If the terminal portability is guaranteed, then a service user can purchase an IPTV terminal in a market and select an IPTV service provider. For this, the IPTV terminal should process a series of pre-configuration, so called provisioning procedure. Telecommunications Technology Association (TTA) established the standard of IPTV terminal provisioning procedure, TTAK.KO-08.0026. In this paper, we explain the revised standard TTAK.KO-08.0026/R2, and introduce the architecture, functions, operating procedures and parameters of the IPTV terminal provisioning system that we implemented based on it. Finally, we discuss the future issues of the standard of the IPTV terminal provisioning procedure.

Purpose - Most of the amendments to the law on the improvement of the distribution structure of mobile communication terminal equipment, the fully self-sufficient system of terminals, and the separated disclosure system on the terminals are aimed at securing transparency of the distribution structure by eliminating or reducing handset subsidies. This study investigates what items are important for the purchase of mobile phones in various and rapidly changing mobile phone markets from the consumer's point of view and tries to make a strategic suggestion for future mobile distribution strategies. Research design, data, and methodology - The procedure of this study takes place in four steps. In step 1, only the SF type respondents selected for this study were extracted through MBTI analysis. In step 2, they were divided into three hierarchies for the AHP analysis and each element was arranged. In step 3, the AHP analysis was converted to a Fuzzy-AHP number using the trigonometric centroid method. This was to eliminate the ambiguity of the response by converting into a fuzzy number even if data consistency was maintained with CI value below 0.1. In step 4, the number of converted 2-layer and 3-layer was combined to derive the priority when the final handset is selected. Results - First, the highest importance among the four items in the second tier was the terminal function item, followed by brand, price, and design item. Second, in the third tier, the highest importance was level of after-sales service, followed by device price, processing speed, ease of use, usefulness, and rate system. Third, the arithmetic average of the determinant of the fuzzy function showed that processing speed, ease of use and usefulness in the function item, level of after-sales service in the brand item, and device price in the price item were the five most important factors among 16 choice factors. Conclusions - First, there will be a change in the consumption patterns of consumers who have compared distributors and dealers to purchase handsets with more subsidies. Second, it is highly likely that people will purchase new handsets only when they need to change their devices because they can not receive subsidies by switching phone brands any more.

In this paper, mobile multimedia service is defined as a service which is used for Internet or multimedia contents without regard to place in the mobile or wireless environment. The purpose of this paper is to search consumer's purchase decision factors by means of literature review and expert's opinion and to analyze a purchase decision structure and its weight. Some implications were found. Firstly, mobile multimedia service purchase factors relating to cost and quality are more important than external causes. Secondly, cost is more important than quality, that is different from result of mobile telecommunication and high-speed Internet service. Thirdly, direct effect such as pertinent charging and terminal price is more important than indirect effect such as pricing differentiation. Finally, main features of service such as mobility and contents are more important than additional characteristics such as personalized service.

The purpose of this study is to explore the nature of the relationship between several factors representing perceived port service quality and the adaptability to the marketing strategy of container terminal. An empirical study was carried out to examine not only the determinants of port service quality using PZB's SERVQUAL model but also its implications to the service marketing strategy. The data investigating the determinants of port service quality were collected from 136 managers from shipping companies by the use of questionnaire method. Factor analysis and t-test were carried out to analyze the data. The results of this study were as follows ; First, Shipping companies perceive the port service quality on two the dimensions of personnel and material aspects. Second, Shipping companies put more emphasis on the reliance of port service quality even though the port authority offers good facilities and materials as parts of port shipping quality. Third, There is a significant relationship between the purchase intention and the customer satisfaction. These findings help not only to formulate service marketing strategy based on service quality but also to be a concept tool to enhance port service quality.

The existing HiPassPlusCard system is composed of the HiPassPlusCard, a Purchase SAM, a Purchase terminal, a settlement system and OBU. However, this system is confronted by the problem with its incompatibility. This problem occurred because the technology companies made cards in their own ways in respect of the parts which were not yet set by KS standard. Thus if existing HiPassPlusCard user wants to use any other public transportations, user would have to buy other cards and have to bring all them. Also if the HiPlusCard wants to extend their business to apply its technology into infrastructure of the other companies, the HiPlusCard has to construct infra independently so that it causes the such problems of duplicated investment. To solve these problems, we have analyzed and upgraded the existing HiPassPlusCard system, and we designed and developed the Nation-wide Interoperable HiPassPlusCard system. Then the conformity test demonstrated that it is efficiency-oriented and technically performs well. Also we, the HiPlusCard, the Korea Financial Telecommunications & Clearings and the KORAIL NETWORKS, run the Test-bed in Gwangju for 6 months. The test-bed indicated that Nation-wide Interoperable HiPassCard system practically works well.

The existing K-CASH system doesn't allow compatible between different regions, different public transportations and the technologies made by different operators. If a K-cash user wants to use public transportation charged not by K-CASH but other operator, then he or she would have to get other type of card available for that transportation. Also, the incompatibility of the existing K-CASH might cause unnecessary expense because similar systems would have to be doubly constructed if the K-CASH operator would like to install the K-CASH system on the same infra as the other operators already did. As a result, a system which allows people to use just one card for their convenience regardless of regions, types of transportation and operators has been strongly demanded. In this paper, we developed Nation-wide Interoperable K-Cash system, Nation-wide Interoperable K-CASH Card, Purchase terminal, Purchase SAM and Settlement system that were updated from the existing K-CASH system. And we performed a conformity test to confirm performance. Also Korea Financial Telecommunications & Clearings and the KORAIL NETWARKS and the HiPlusCard joined for the testbed in Gwangju for 6 months. This result of testbed finally proved that the Nation-wide Interoperable K-CASH system is completely compatible.

Although the existing X-CASH card system observes the KS standard for a transportation card system, there has been an issue for interoperability between X-CASH and other public transportation system due to the partially undefined part in the standard. This issue is followed by the inconvenience of the existing X-CASH users. If the existing X-CASH card user wants to get any other public transportations which are not interoperated with X-CASH, the user would have to buy other cards. Consequently, some users have to bring more than one card with them. In addition, it is almost impossible that the existing X-CASH system operator makes the X-CASH card available for the infrastructure built by other cards operators because their technologies are too much different. The X-CASH operator must construct its own infrastructure on the same route and it would cause an unnecessary loss of expense and labor. To solve these problems, We modified the existing X-CASH system and developed the Nation-wide Interoerable X-CASH system which lets both the existing X-CASH card and Nation-wide Interoperable X-CASH card work. This developed X-CASH system consists of the purchase SAM, the purchase terminal and the settlement. And The conformity test for it was successfully authorized. Also we, KORAIL NETWORKS, have done the test-bed on this Nation-wide interoperable X-CASH system in Gwangju for six months with Telecommunications & Clearings, the HiPlusCard Corporation. This test confirmed that the Nation-wide Interoperable X-CASH system would practically work well.
