오늘날 기술 경쟁이 심화되면서 업체간 기술 격차는 큰 차이를 보이지 않고 있다. 그래서 각 기업들은 자사 제품의 경쟁력 확보를 위해 다양한 분야를 연구하게 되었고, 그 결과 소비자들에게 높은 기술력을 제공하는 것보다는 새로운 경험을 제공하는 것에 대한 중요성이 점점 부각되어 가고 있다. 그래서 본 논문에서는 PC 에서 웹 서비스(Web-Service)를 사용하는 사용자의 경험을 IPTV 에서도 경험할 수 있는 방법에 대해 연구하였고, 그 중 사용자들이 좀더 편리하고 쉽게 웹을 경험할 수 있는 Widget UI를 제안한다. 우리가 제안하는 IPTV 에서 웹 서비스를 제공하는 Widget UI 는 서로 독립적인 Widget 서비스들로 구성되어 있으며, Widget 서비스의 개수와 배치는 사용자에 따라 다르게 제공된다. 즉, 우리는 IPTV 를 위한 사용자 맞춤형 웹 서비스 제공 Widget 사용자 인터페이스를 제안한다. 또한 각 Widget 서비스의 정보 검색은 리모컨의 4 방향 키를 사용하도록 제공함으로써 사용자에게 사용의 편리성을 증대시키고 학습 피로를 감소시킬 수 있다. 이러한 학습 편의성과 사용 편리성을 사용자에게 제공함으로써 기존에 IPTV 에서 사용하기 힘들었던 웹 서비스의 사용성을 크게 향상 시키는 효과를 기대할 수 있다. 우리는 이러한 Widget UI 의 사용성을 객관적으로 평가하기 위해 UI 전문가들을 대상으로 전문가 평가를 실시하였으며, 결과 비교를 위해 다른 웹 서비스 제공 UI 들도 추가적으로 전문가 평가를 실시하였다. 전문가 평가 결과 본 논문에서 제안한 Widget UI 가 타 UI 들에 비해 높은 사용성 평가를 기록하였으며, 이 결과는 결국 우리가 제안한 Widget UI 가 IPTV 에서 웹 서비스 정보를 제공하는데 있어 효율적이고 적합한 방식임을 보여준다.

Recently as the user experience's importance has been emphasized, there has been many tries of various research methodology in order to understand the user. Specially, as the political investigation method's user understanding method based on the statistical analysis so far has encountered a limit, there has been a continuous tendency to try to introduce a humanitarian or cultural anthropological methodology. As part of this effort, there has been many tries of various approach methods of the Ethnography which is the cultural anthropological typical research methodology, but among those the Diary Study Method is mentioned as one of the effective methodologies. Therefore this thesis applies the Diary Study Method to the notebook PC bundle SW's attitude research and tries a deep rooted research about the user attitude. Also centered to the project of understanding the notebook PC bundle SW's user receptivity. it shows a specific example of the Diary Study applied to the user understanding. Through this process, we will examine the summary about the Ethnography research method, and will discuss an effective research methodology by through the process of analyzing and deducting the user inclination by applying and designing the Diary Study to the project. That is to say, it was progressed by actually applying the research methodology through a specific case, with the purpose of breaking away from the textbook discussion and progress with an application aspect discussion. Through the current research, we will verify an active user-inclined process about the user's notebook PC SW, and it is expected to be useful in establishing a SW UX strategy and distribution related to the bundle software.

The purpose of information retrieval is to help users solve their problems. To fulfill the purpose the user's problem needs to be focused on. The purpose of this study is to identify components and the structure of the user's problem in an academic research environment. From this study it was found that the scientific problem dealt within an academic environment is complicate and the problem is composed of 8 topical and 4 non-topical components. And they could be organized into a stucture. This study has three implications for user-oriented information retrieval. (1) The components and the structure of the problem need to be the framework for the effective information retrieval process and for the evaluation of information retrieval. (2) The research methodology used in this study can be applied to other information service situations and this will result in greater practical implication of a study for more effective information retrieval. And (3) for more effective user-oriented information retrieval, the user needs to be observed and studied in the actual' situation. This study showed that the complicate problem of the actual user can be studied in a systematic way and this resulted in important implications for information retrieval.

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.

Due to recent interest in user experience and its significance, much research surrounding this theme is now being conducted. If user experience is defined as the emotions and satisfaction the user feels while using the product, how much of such experience will contribute to the overall satisfaction of using the product? In this research, user experience during usage of a product and the satisfaction acquired by it were investigated. The same experiment was conducted in South Korea and the United States of America in order to get more generalized experimental results. Amongst the six representative user emotions expressed while using a product, 'Satisfaction in Usability', 'Discomfort or Displeasure', and 'Excellence' correlated the most. The above three factors were found to be of the most influence concerning satisfaction of the product. The significance of this finding is that aside from focusing on the attractiveness of the product's exteriors and design, one should be concerned on the ease of usage and effectiveness as well as usability of the product, all of which contribute to how efficiently a consumer will utilize the product.
