We analyzed 53 representative Korea oriental medicine web sites to measure the credibility and satisfaction using objective valuation basis. First we analyzed qualitatively the general sites' characteristics composed of operational status, kernel service, organization and payment. Secondly we calculated the sites' credibility categorized as expertise factors, trustworthiness factors, sponsorship factors and other factors to deduce the key factor. we expect the result can be used as the indicator for developer to improve the Korea oriental medicine web sites. And we expect the result can be used as the objective credibility for the web user to confirm the contents of Korea oriental medicine web sites.

In the 2000s, the PC package game market has withered, but the internet based on-line game, the wireless internet based mobile game and high-powered console game market have been main stream. Among those markets, mobile game market has rapidly increased because it has 'mobility' that overcomes the limitation of time and area. But, unlike other platforms, mobile game user have to pay the higher price for download mobile game contents through the wireless internet and mobile game developer have to overcome the limitation of storage memory capacity.of mobile phone. Chiefly, the image data consume the storage capacity of mobile game contents, this paper present a technology to optimize image data for mobile game contents through analyzing type of compression method and image formats.

At present, Authoring tools, which are used to develop the WIPI applications are less convenient to be coded. Usually, the programming tools only focus on the grammar while scarcity of visualization. Developer forced directly codes all times during the development by this cause. As a procedure for rapid WIPI Application Development, in this paper, WIPI API High Level Component is first visualized, in order words, graphic control is developed. Second this control is used in designing the mobile layout. Then UI Markup Language and source code can be generated automatically. With this view, we propose the JIML(Jlet Interface Markup Language) with UI Markup Language based XML of WIPI Jlet Platform and also present the transformable rule for generation to the WIPI code about WIPI Jlet UI from offered JIML. Also we implement the WIPI Jlet Generation System to make the generation to JIML, WIPI code. The Implemented System provides efficiency when developing WIPI Business Application, and helps to enable rapid development.

Today, most of all the query processors in the world generally use the 'Pipelining' method to acquire fast response time (first record latency) and less memory usage. Each of the operator nodes in the Query Execution Plan (QEP) provides Open(), Next(), and Close() functions for their interface to facilitate the iterator mechanism. However, the embedded database systems for the mobile devices, based on the FLASH memory, usually require a function like Previous(), which returns the previous records from current position. It is because that, in the embedded environment, the mobile devices cannot fully provide it main memory to store all the query results. So, whenever needed the previously read records the user (program) should re-fetch the previous records using the Previous() function: the BACKWARD data fetch. In this paper, I introduce the 'Direction Switching Problem' caused by the Previous() function and suggest 'Block-wise Skipping' method to fully utilize the benefits of the block-based data transfer mechanism, which is widely accepted by most of the today's relational database management systems.

As service-oriented software is considered as one of solutions to fulfill the users' needs in internet service environment, it has been increased the demands of reliable service development by the composition of internet services. However a critical issue in the service development approach is to satisfy the performance requirement as well as the functional correctness for the developing services, because impatient user multiply clicks the request-button of service without a short waiting. This paper proposes a framework to examine the performance of composite service. Our testing framework provides the data of service response time to service developer by measuring the service execution time. We develope an Aspect-based timer service, and weave the service with existing services to measure the execution time. Additionally, we perform some experiments to confirm the usefulness of performance test for composite service. This framework can support to develop a good performance service by substitution of the dragging service with another new service that will be a component of composite service.

In this paper, we propose an ordering chatbot that can process multiple keywords based on recursive slot-filling method. In general, in case of an order service using chatbots, the whole order process is performed only according to the sequence defined by the developer. That is, among all the information needed for the whole order process, only one input can be processed at one time. In order to reduce processing step for the order, we propose a recursive slot-filling method which fills out multiple slots per one time by extracting multiple keywords. First, a keyword array for the order is created according to the order related information. Next, from the input sentence of a user, multiple keywords is extracted. Corresponding slots for a keyword array will be filled with the extracted keywords. Finally, recursive routine will be executed to fill out all the blank in the keyword array. The usability and validity of the proposed method will be shown from the implementation of a smartphone application.

In this paper, we proposed a sniffer to detect permission smells from developer and third-party libraries' code. Moreover, we conducted an empirical study to investigate unnecessary permissions on large real-world Android apps. Our analysis indicates that permission smell extensively exists in Android apps. According to the results, permission smells exist in most Android apps. In particular, third-party libraries request permission for functionalities that are not used by developers, which cause more smells. Moreover, most developers do not properly disable unnecessary permissions that are declared for third-party libraries. We discussed the impacts of permission smells on user experiences. As a result, the existence of permission smell does not impact the number of downloads. However, apps that have more unnecessary permissions have received lower ratings from users.

In the past, the enlargement of perception through media was 'information'. From now on, however, the primary objective of media is to consist not in conveying information but in sharing the values of 'emotion' and 'experience' that are perceived through information. Individual emotional becomes an issue due to the limitations of the ideology of modernism and the pervasiveness of the autonomous perception in the human thinking that started in postmodernism. If we once again talk about a function-focused, sensible approach for the sake of marketing in the current era that has impinged on the limits of mammonism, we must keep in mind that 'emotion,' presently retaken as the originary, human value and the value of new communication, may come to an end any time. Therefore, th current thesis is designed to examine John Dewey's 'transaction' as a method for figuring out the concept of emotion, the perceptional function latent in humans. Dewey's 'transaction,' which is a term that refers to the reciprocal relationships between humans and environment and the accompanying totality of perceptive process, interprets human emotion, user experience and environment as the organic, circular relationships. For such understanding, one must break out of the boundary of the past, dichotomous communication between the subject and the object to expand into the perceptional relations in a wider environment, in order to seek design methods that would help dismantle the borderline that has so far separated the developer from the user, share sensibilities, and express experiences.

As a comparative study on the value of design concept between service provider (Developer) and service receiver (Customer) group, the aims of this study was to present a service model focused on Continuous positive airway pressure (CPAP) based on U-health care and user environment. Double Diamond-based methods led to a case study that conducted jointly by the department of otolaryngology in U hospital, Ulsan. By targeted on Sleep Apnea patients from the stage of diagnosis to CPAP treatment, variety of meaningful experiences have been extracted and classified into several types of customers. In the final analysis of the 13 service scenario models, Kano Satisfaction and Potential Customer Satisfaction Improvement Index (PCSI) were conducted with the customers, yet Score Model and Concept Position were evaluated by the service provider groups who engaged in development services. The results of this study showed that 7 items in the total of 12 items reached a consensus of viewpoint on value between service receiver and service provider, which the attributes of the service model are based on user environment. Whereas the other 5 items showed the divergent viewpoint on value which included the attributes of U-healthcare service model.
