In this study, we designed and verified a research model that identifies the correlation between public library organizational justice, the engagement of service contact members, and user orientation. First, distributive justice was found to have a positive effect on engagement. Second, interaction justice was found to have a positive effect on engagement. Third, procedural justice was found to have a positive effect on user orientation. Fourth, engagement was found to have a positive effect on user orientation. As a result of structural equation model analysis, it was analyzed that engagement had a greater influence on user orientation. Service contact members who have the attitude of having organizational members take voluntary and self-sacrificing actions in library operation and are willing to be positively immersed in their work can take user-oriented actions that provide services with users as the top priority. Because the possibility is high. It has practical significance in that it suggests strategies and improvement plans that can be helpful to libraries.

This study is designed to analyze the effect of entrepreneurship orientation of owner managers on product innovation performance through user innovation participation by using Korea Innovation Survey 2014 (KIS 2014) conducted by STEPI (Science and Technology Policy Institute). The findings show that entrepreneurial orientation of owner managers measured by a proxy variable of ownership ratio has positive relationship with innovation performance of firms. They also present that user innovation activity has a partial mediating effect on the relationship between the entrepreneurial orientation of owner managers and innovation performance of firms. This study suggests that the higher the entrepreneurial orientation of the owner manager, the higher the innovation performance. The innovation performance can be intensified when the open innovation strategy is implemented through the user participation.

In this paper, we present an user interface which can show some 3D objects at various angles using tracked 3d head position and orientation. In implemented user interface, First, when user's head moves left/right (X-Axis) and up/down(Y-Axis), displayed objects are moved towards user's eyes using 3d head position. Second, when user's head rotate upon an X-Axis(pitch) or an Y-Axis(yaw), displayed objects are rotated by the same value as user's. The results of experiment from a variety of user's position and orientation show good accuracy and reactivity for 3d visualization.

The purpose of this study is to find out the difference of sense of self-efficacy and stress encountering strategy of university students under the stress situation depending on the smart-phone user group (addiction group, general user group). For this purpose, the study issues are established as follows. First, it has analyzed what is the correlation of smart-phone addiction, sense of self-efficacy, and stress encountering strategy. Second, it has studied if there is any difference of sense of self-efficacy and stress encountering strategy for the smart-phone user group. In order to verify such study issues, For 1,670 university students in the Chungcheong area, smart-phone addiction scale, sense of self-efficacy scale, and stress encountering method scale were administered. Looking into the study result, first, as a result of the relativity analysis, it displayed the correlation of preference of test difficulty, self-control efficacy and important negative from the smart-phone addiction and sense of self-efficacy. In addition, all sub-variables of smart-phone addiction and avoidance orientation from the stress encountering strategy displayed the important positive correlation, and from the smart-phone addiction, the virtual world orientation and pursuit of social-support displayed the important negative correlations, and all sub-variables (interference with ordinary living, virtual world striving direction, withdrawal, resistance) of smart-phone addiction and problem solving-orientation displayed the negative correlation. Second, as a result of verification for the difference of the smart-phone addiction group and general use group following the sense of self-efficacy, the general use group is shown to have higher self-control efficacy sense than the addiction group. And third, as a result of verifying the difference of stress encountering following the smart-phone addiction group and general use group, the addiction group is shown to be lower than the general use group in terms of social support pursuit and problem solution orientation with the avoidance orientation shown to be higher. This type of result is expected to provide the base data when developing the smart-phone addiction preventive education program by finding out in details for the characteristics of smart-phone addiction group for university students.

This paper proposed a smart-phone based user movement state identification algorithm. Then movement state of the user is identified by calculating the location and moving speed using the GPS sensor, and detailed movement methods are identified by analyzing the data from the Orientation sensor. In this study, two sensors of the smart-phone were used to implement the user movement status identification algorithm and to perform tests. The reference values of the speed and orientation required for the identification of the movement type were defined based on the experimental data. The results of this study showed that the movement type of a smart-phone user can be identified using the user movement state identification algorithm.

The purpose of this study was to explore the role orientation that librarians are expected to carry during their career-life. More specifically, this study examined the pattern of librarians subjectivism related to attitude, belief, and confidence. Q questions were made of 36 items, including personal value system and role attitude. P sample included 23 librarians. Data were collected for 8 days (from April 15, 2005 to April 22, 2005). Analyses showed the following results. First, librarians role orientations were classified into 3 types: user-centered orientation, organization-centered orientation, and expertise-centered orientation. (1) The first type librarians were interested in having good relationships with users, while emphasizing the importance of providing good services to the users. (2) The second type of librarians were concerned with social function of the library, while placing highlight on their roles as organizational members. Among them, achievement evaluation was regarded as an important indicator of personal success. They were interested in having stable organizational culture, as well as economic growth of libraries. This orientation was dominant among married members. (3) The third type of librarians focused on librarians role implementation and professional achievement. They showed interest not only in the improvement of librarians creativity and the growth of expertises, but also the expansion of retraining opportunities. This orientation was conspicuous among female librarians. Second, several commonalities and differences were consistently found among librarians. The first type was interested in user-centered orientation(user contact, need satisfaction, self dignity, etc.). The second type was interested in organization-centered orientation(creativity, expertise growth, retraining opportunity, professional achievement. self-respect, etc.).

The increase of the number of smartphone applications has enforced the importance of new user interface emergence and has raised the interest of research in the convergence of multiple sensors. In this paper, we propose a method for the convergence of acceleration, magnetic and gyro sensors to recognize the gesture from motion of user smartphone. The proposed method first obtain the 3D orientation of smartphone and recognize the gesture of hand motion by using HMM(Hidden Markov Model). The proposed method for the representation for 3D orientation of smartphone in spherical coordinate was used for quantization of smartphone orientation to be more sensitive in rotation axis. The experimental result shows that the success rate of our method is 93%.

The aim of this study is to develop and evaluate an efficient camera calibration method for vision-based head tracking. Tracking head movements is important in the design of an eye-controlled human/computer interface. A vision-based head tracking system was proposed to allow the user's head movements in the design of the eye-controlled human/computer interface. We proposed an efficient camera calibration method to track the 3D position and orientation of the user's head accurately. We also evaluated the performance of the proposed method. The experimental error analysis results showed that the proposed method can provide more accurate and stable pose (i.e. position and orientation) of the camera than the conventional direct linear transformation method which has been used in camera calibration. The results of this study can be applied to the tracking head movements related to the eye-controlled human/computer interface and the virtual reality technology.
