Purpose: Marine transportation companies must improve service quality to secure competitive advantage and continuous relationships with customers. This study explores the value and necessity of service quality in the industry by empirically identifying the factor that would have the largest effect on the improvement of service quality, also examining whether such improvement may actually influence continuous relationships. Research design, data and methodology: Based on an online survey with those in the Korean marine transportation industry, this study conducted statistical analyses using structural equation modeling. Based on relevant previous studies, the current study constructed a total of 55 survey questions. Finally, 281 questionnaires were collected, but 68 were excluded owing to invalid responses. Results: Information service attribute had the largest effect on service quality, whereas communication did not demonstrate a significant influence. In addition, distribution and information services exerted a positive effect on service satisfaction through service quality, and finally influenced relationship continuity. Conclusions: The results shows that marine logistics service quality strategies which were centered on time or local factors, should be considered in terms of the development of innovative services. In particular the improvement of information service systems and strategies in changed business environment.

The purpose of this case study is to demonstrate the effectiveness of the disruptive innovation strategy based on the Resources Process Values(RPV) theory for a successful firm. Disruptive innovations seemed not initially perform well enough to be sold or used successfully in markets. The products and services used disruptive technologies have not been as effective as those used in the established markets. However, they have other attributes such as simplicity, convenience, and low cost, which appeal to a new, small and initially unattractive set in new or low-end applications. The Hyundai Heavy Industries Co.(HHI) performed the Jubail Industrial Harbour Project(JIHP), which built the Open Sea Tanker Terminal(OSTT) in Saudi Arabia, using the disruptive innovation strategy in order to lower the manufacturing cost of the offshore jacket and to complete the project successfully. The HHI developed the design and drawing systems to manufacture the jacket and also developed the HYundai Jacket Analysis System(HYJAS) software to use the structural analysis against stresses from rolling and pitching of the barge while transporting the jacket by sea.

This study focuses on investigating and analyzing overall information use behavior of the health fields researchers. Questionaries were 116 researchers in there nursing university or college and EMT college. Four areas were tested on the basis of the purpose that there would exist unique characteristics in the information seeking behavior of health fields researchers. The findings of the study shows that health fields researchers prefer monographs and journals; they tend to use current materials; the first information source for their research activities is the cited references in the book or journal article; they are likely to delegate literature searching to the librarian, but they tend to conduct direct searching in online setting; in general, they react positively for the rapid change in information environment caused by recent development of information technology. It is emphasized that to design an efficient information system and provide an effective information service in the health science related library or information center, it is essential to consider the major characteristics and attributes of health fields researchers in terms of their information use behavior.

In this paper, a platform was proposed that can service the streaming of location based real-time video-clip for smart-travel-services to work with PPL(Product Placement). The location information of drama like as LTE GPS and Beacon were used to provide the drama video with the PUSH service. And PPL DB with the attributes like as picture, video, music and URI(Uniform resource Identifier) was designed. As a result, this platform could provide the location based video streaming service that could replace the original PPL properties, color or shape, with the other properties by the interactive tagging the PPL DB in drama scenes. The proposed platform could provide the location based real-time video streaming service that can alter the PPL properties with the request of service provider.

This paper proposed a method that can be simply analyzed instead of the basic general Fuzzy rule that its insufficient characters are cut out. Based on the proposed method. Rough sets are used to eliminate the incomplete attributes included in the rule and also for a classification more precise; the agreement of the membership function's output extracted the maximum attributes. Besides, the proposed method in the simulation shows that in order to verify the validity, compare the max-product result of fuzzy before and after reducing rule hosed on the rice taste data; then, we can see that both the max-product result of fuzzy before and after reducing rule are exactly the same; for a verification more objective, we compared the defuzzificated real number section.

The purposes of this study was to investigate importance and performance for coffee quality attributes in Korean and Chinese university students by 3 types of coffee; coffee in coffee houses, coffee in vending machines and canned/bottled coffee. Survey was done for 360 students in Daejeon with developed questionnaires including general information, favorite type of coffee and 15 quality attributes of coffee. Finally, data from 168 Korean and 126 Chinese university students was used for statistical analysis by SPSS 18.0 package program. Results of this study were as follows: for favorite type of coffee, the rates of coffee in coffee houses, coffee in vending machines and canned/bottled coffee were 43.0% 34.8% and 22.2% in Korean students and 8.7%, 78.0%, and 12.2% in Chinese students, respectively. Comparing Chinese students and Korean students showed higher importance for several quality attributes of coffee in coffee house (p < 0.05), but lower importance for most quality-attributes of coffee in vending machine (p < 0.05) and canned/bottled coffee (p < 0.05). According to importance and performance analysis, strategies for increasing satisfaction were to improve 'price' of canned/bottled coffee in Korean students, and 'taste', 'volume', 'concentration' and 'variety' of canned/bottled coffee and 'freshness' of coffee in vending machine in Chinese students. These results suggested that differentiated marketing plans between Korean and Chinese university students should be needed in coffee industry.

The principal objective of this study was to assess the behavior of customers who visit hotel buffet restaurants. This information will provide us with a good marketing strategy, allowing us to control for different customer characteristics and focus on giving marketers useful clues that make it easy to understand the selective attributes for hotel buffet restaurants. Thus, the application of selective attributes is predicated on the results of the analysis. Additionally, this survey was completed by regular customers. The following are the concrete results of the study. First of all, customer's behaviors differ radically with the selective attributes of hotel buffet restaurants. The most crucial factors were found to be "quality of food", "hygiene & cleanliness", and "service". These factors have nothing to do with customer characteristics & demographic features. "Opinions of their relatives, colleagues" and "experience of restaurants" are all sources that substantially influence the selective attributes of restaurants and this is the only way to survive the ever-changing market situation. Finally, hotel buffet restaurants generally attempt to lure customers with healthy food, special corners, fresh vegetables, and fresh sashimi, as compared to the services provided by hotel outlets. According to upgrade service quality & restaurant interior, also, buffet restaurants tend to provide guests with a more charming. Food service companies should consider the question "what really is service?" and thus seek to provide a variety of events. Preparing for unforeseeable market situations, we should execute efficient marketing strategies in order to assure continued customer satisfaction.

Various supplementary authentication methods are used to supplement user authentication and authorization provided by existing password verification online1. In recent years, authentication and authorization methods using user attribute information have been studied and utilized in various services. User attribute information can be divided into static information and dynamic information. The existing methods focus on research to identify users using dynamic information or to generate challenge questions for user reauthentication. Static information such as a user's home address, school, company, etc. is associated with dynamic information such as location information. We propose a method to verify user attribute information by using the association between two attribute information. For this purpose, the static information of the user is verified by using the user's location record which is dynamic information. The experiment of this paper collects the dynamic information of the actual user and extracts the static information to verify the user attributes. And we implemented the user attribute information authentication system using the proposal verification method and evaluated the utility based on applicability, convenience, and security.
