소셜 네트워크 서비스의 확산과 더불어 소셜 네트워크 게임(이하에서는 소셜게임이라 함)이 부각되고 있다. 한편, 소셜게임이 인기를 끌면서 소셜 네트워크 서비스가 더욱 확산되는 계기가 되기도 한다. 사용자들을 소셜게임에 몰입하도록 유인하는 요인이 무엇인가를 파악하면 소셜 네트워크 서비스가 더욱 발전할 수 있는 방안을 찾을 수 있다. 따라서 본 연구는 사용자들을 소셜게임에 몰입하도록 유인하는 요인이 무엇인가를 분석하는데 있다. 본 연구에서는 대표적인 소셜 네트워크 사이트라 할 수 있는 페이스북의 소셜게임 사용자들을 대상으로 설문조사를 실시하였다. 280명의 사용자들을 대상으로 한 설문을 통해, 소셜게임에의 몰입, 게임스토리, 게임그래픽, 게임사회화, 게임 통제력, 게임 사용용이성의 관계를 구조방정식모형으로 분석하였다. 특히, 게임 사회화와 게임그래픽은 몰입에 직접적으로 영향을 주기도 하며 게임 사용용이성을 통해 간접적으로도 영향을 주었다. 한편, 게임스토리는 몰입에 직접적으로만 영향을 주고, 게임 통제력을 게임사용 용이성을 통해 간접적으로 영향을 준다. 본 연구는 몰입이론과 기술수용이론을 토대로 하고 있지만, 소셜게임에서의 몰입에 대한 최초의 연구이기 때문에 후속 연구에 지침이 될 수 있다. 또한 소셜게임을 개발하는 사업자들이 무엇에 역점을 두고 게임을 개발하고 서비스해야 할 것인가에 대한 지침이 될 수 있다.

모바일폰의 컨버전스가 가속화됨에 따라 사용자가 습득해야 할 정보량이 증가하였고, 사용자들이 이를 이용하기 위하여 학습과 숙련의 과정을 거쳐야 하는 부담이 발생하게 되었다. 모바일폰의 주 사용자층인 20-40대 외에 10대와 50대 이상의 이동전화 이용률이 꾸준히 증가하여 실버폰과 키즈폰 시장이 형성될 조짐을 보이고 있지만, 제조사에서는 획일적인 인터페이스 디자인만을 제공하여 다양한 사용자 층의 요구와도 서로 맞지 않고 있다. 이에 본 연구에서는 모바일폰의 휴먼인터페이스 요소 중 메뉴요소에 해당하는 메인메뉴의 네비게이션 방식에 중점을 두어 각 사용자 유형별로 사용성을 측정하였다. 국내외 모바일폰 제조사에서 2006년 출시된 제품에서 메인메뉴 네비게이션 방식을 추출하여 8가지로 분류하였으며, 이를 토대로 플래시 기반의 시뮬레이터를 제작하여 사용성 측정에 이용하였다. 모바일 사용성 평가를 위한 요인을 중심으로 10대부터 60대 이상의 다양한 사용자를 대상으로 시뮬레이터 사용을 관찰하여 분석하였으며 또한 기존에 사용하고 있는 모바일폰 기종을 고려하여 설문지로 사용성에 대한 만족도를 평가하는 방식도 병행하였다. 본 연구에서는 사용자 유형별로 사용성이 높은 인터페이스를 선별하고 사용자의 개성과 선호도를 고려한 선택적인 UI 개발방향을 제안하였다.

Web personalization has focused on extracting web pages interesting to users, to help users searching wanted information efficiently on the web. One of the main methods to achieve this is by using queries, links and users' preferred words in the pages. In this study, we surveyed from the web users the features of pages that are considered important to themselves in selecting web pages. The survey results showed that the content of the pages is the most important. However, images and readability of the page are rated as high as the content for some users. Based on this result, we present a method for maintaining relative weights of major page features differently in the profile for each user, which is used for personalizing web search results. Performance of the proposed personalization method is analyzed to prove its superiority such that it yields as much as 1.5 times higher rate than the system utilizing both queries and preferred words and about 2.3 times higher rate than a generic search engine.

The purpose of this study is to analyze the EBS special lecture, which is an educational application, from a user 's point of view and to propose a direction for improvement of the user experience according to the GUI design. Firstly, we surveyed the theoretical background and service situation through literature review, and secondly, we surveyed the user experience questionnaire based on 7 principles of honeycomb model of Peter Morville. As a result, the EBS special lecture showed improvement of GUI due to lack of visual part in addition to its use. Based on this research, I hope that the service for improvement of the user experience of the education application will be improved in the future and it will be helpful to study the educational application user experience to be conducted in the future.

The purpose of this study is to study the user experience that provides psychological stability when paying for mobile e-commerce pay one-touch. Through literature and case studies, e-commerce pay one-touch payments were identified, and user experiences were investigated through surveys and in-depth interviews. The survey based on Aaron Walter's model of user needs received a high average of functionality and usability for one-touch payments, but reliability and stability were somewhat low. Afterwards, four design improvement plans were presented to supplement psychological stability by analyzing in-depth interviews conducted based on the User's Eye View of User Experience Design model. This study is expected to be helpful in basic research on the payment experience where you can feel stable when taking one-touch payments.

The providers of meteorological information want to know the level of satisfaction of forecast users with their services. To provide better service, meteorological communities of each nation are administering a survey on satisfaction of forecast users. However, most researchers provided these users with simple questionnaires and the respondents had to choose one answer among different satisfaction levels. So, the results of this kind of survey have low explanation power and are difficult to use in developing strategy of forecast service. In this study, instead of cost-loss concept, we applied satisfaction-dissatisfaction concept to the $2{\times}2$ contingency table, which is a useful tool to evaluate value of forecast, and estimated satisfaction value of 24h precipitation forecasts in Shanghai, China and Seoul, Korea. Moreover, not only the individual satisfaction value of forecast but the user group's satisfaction value was evaluated. As for the result, it is effective to enhance forecast accuracy to improve the satisfaction value of deterministic forecast user group, but in the case of probabilistic forecast, it is important to know the level of dissatisfaction of user group and distribution of probability threshold of forecast users. These results can help meteorological communities to search for a solution which can provide better satisfaction value to forecast users.

강수확률예보에 대한 사용자 행동을 이해하고, 만족도의 변화를 분석하기 위해 2017년 조사된 설문조사 결과를 도입하고, 예보의 가치평가 분야에서 널리 활용되어 온 가치스코어를 만족도 평가에 사용하였다. 분석 결과 예보사용자들은 확률예보를 효율적으로 사용할 수 있는 적절한 임계확률을 인지하지 못한 것으로 나타났다. 동일한 예보라도 분석 시기에 따라 사용자의 불만족 정도가 만족도에 미치는 영향은 다르게 나타날 수 있으므로 사용자들이 민감하게 반응하는 시기를 적절히 구분하여 분석할 수 있어야 할 것이다. 그리고 분석 기간 및 연령에 따라 사용자들의 의사결정 기준인 확률예보의 임계확률을 변화시키는 것만으로 일부 사용자 그룹의 만족가치를 향상시킬 수 있는 것으로 나타났다.

The purpose of this study is to analyze user requirements of photovoltaic generating facilities for detached houses. For the analysis, 202 households that installed photovoltaic generating facilities to conduct a survey. According to the survey results, users mainly demanded 'Reduction in self-burden amount' and 'Maintenance Services.' In addition, when conducting 'Education for photovoltaic generating facilities', they highly wanted to participated in it. Results on the installation status of photovoltaic generating facilities are as follows: Of locations where photovoltaic generating facilities are installed, the most households installed them on the roof, 54%. As for the angle in which photovoltaic module is installed, the range of $25{\sim}35^{\circ}$ was the most common and in the case of installation direction, southern exposure accounted for the rate of 93%. The monthly average generation of households surveyed is approximately 320kWh. Research on technology and policy to address user requirements shown in this study is deemed necessary in the future.

The aim of this paper is to select a distinct vocabulary for understanding the media facade of user and to lay the foundation for a media facade emotional scale. Firstly, we assembled a set of emotional words that were sufficient to represent a general overview of korean emotions, collected from various literature studies. Secondly, we found emotional words from collecting user opinion on the Youtube website. Finally the emotional words were collected from phrase by using non-structural survey. The collected words were integrated according to standards and they were organized 39 pieces that can be used in the survey. As a result, we extracted 21 emotional words for measuring user's emotions expressed while watching media facade, such as 'novel', 'cool', 'awesome', 'gorgeous', 'exciting', 'amazing', 'wonderful,', 'showy', 'great,', 'intense', 'good', 'grand', 'colorful', 'unique', 'variety', 'new', 'fun', 'beautiful', 'luxurious,', 'mysterious', 'satisfactory'. And we categorized the 21 words to form 5 elements by using factor analysis such as 'surprise', 'attention', 'variety', 'aesthetics', 'interest'.
