Collaborative filtering approach for recommender systems are now widely applied in e-commerce to assist customers to find their needs from many that are frequently available. this approach makes recommendations for users based on the opinions to similar users in the system. But this approach is opened to users who present their preference to items or acquire the preference information form other users, noise in the system makes significant problem for accurate recommendation. In this paper, we analyze the relationship between the standard deviation of preference ratings for each user and the estimated ratings of them. The result shows that the possibility of the pre-filtering condition which detecting the factor of bad effect on the prediction of user's preference. It is expected that using this result will reduce the possibility of bad effect on recommender systems.

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.

Among the standards of CALS, CITIS(Contractor Integrated Technical Information Service) is a standard in information share procedure which manages all data and services occurred between a contractor and a purchaser. CITIS services have some security problems like authentication problem and repudiation problem, when they are implemented using the Internet. To solve these problems, CITIS needs a user certificate system which can allow to access important information only to qualified users. This paper proposed a PKI(Public Key Infrastructure) Certificate Authority for CITIS, and created a real User Certificate System which can be adjusted to circumstances of real CITIS.

As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.

The health care services are the most basic social institutions that are provided to citizen including disabled persons for improvement of health. However, the study of the difference of health care services according to the speech therapy use in the people with speech-language disorders was insufficient. The aim of this investigation was to compare the awareness of health care services and characteristics of people with speech-language disorders according to speech therapy use. The researchers selected 229 people with language disorder using raw data of National Survey of the Disabled Person (2017). We compared the characteristics and health care services of people with speech-language disorders by distinguishing between speech therapy non-users and speech therapy users. Among the 229 people with language disorder, speech therapy users were 37 persons (16.2%). In comparison with non-users, users were younger, more preschoolers, more family incomes, and intellectual disabilities and autistic disorder were the most common types of disability enrollment. Users had a lower proportion of unmet medical needs than non-users. For the reasons of unmet medical need, there were 6.8% and 6.3% of the "economic reasons" and "communication difficulties" Both users and non-users responded that "disability management services" need to be strengthened by the government. In conclusion, we suggest that access to health care services needs to be increased to lower the barriers of speech therapy use.

Information and telecommunication technology are causing revolutionary changes in society and its institutions. It is especially more so in the field of science and technology (S＆T). Extraordinary advances in microelectronics have fueled this information revolution, and S＆T scholarly communication are changing rapidly and dramatically because of it as are the needs of science and technology information users. To seek pertinent scientific and technical information (STI) is a complex matter in this electronic digitalized age of information environment. Before we meet information needs of scientists and engineers effectively, we must know the Purpose for their seeking the information, the type of information they sought, and what we have been providing to satisfy their needs.(omitted)

In this research, we have developed a model that can explain the potential customer's needs for the potable Internet service, a concept with 'QoS guaranteed lower-price high speed mobile Internet service. Based on the developed model, we have also derived some empirical implications for the business firms interest in the potable Internet market. The developed model is incorporating a survey result, answering of potential customer's attitude for the portable Internet service, from the subscribers to the Internet service, wireless LAN service, and mobile Internet service. As a result, we have found that a very innovative group, such as wireless LAN users and 20's age group using mobile Internet service, could be the most attractive market segment. Moreover, the aspects of the service coverage and the price competitiveness at the service launching stage could be the most critical success factors for the portable Internet service.

The goals of healthcare design based on the human rights to manage physically, psychologically, and emotionally healthy life. The healthcare designs, however, have been criticized not to reflect their primary users, patients' and families' needs, under the management strategy centered by the functional efficiency. The study focused on the patients' room design on the users' perspective. The design criteria for the patients' room in Japan, Germany, Australia, U.S. and Korea were examined and compared. The subjects of analysis are the floor plans of general hospital recently planned and built in Korea and Japan and the standard floor plan models proposed by prior studies in Korea and AusHFG in Australia. Results and conclusions are as follows: (1) the patients' room has developed as a place where the users manage their living during inpatient period and has become a private room. (2) The guidelines for patients' room size in Korea and Japan are not enough considering the users' diverse activities compare to those in U.S. and Australia. (3) The guidelines of Korea should be reconsidered for the users' comfortable lives. It must include the specific criteria of the enough space between beds, the storages, and other assistant tools and facilities. (4) The desirable types of patients' rooms by the numbers of users in Korea are proposed as a one-bed room type and a four-bed room type.
