The numbers of multi-year droughts due to climate change are increasing worldwide. Boryeong Dam, located in Chungcheongnam-do, South Korea, was also affected by a 4-year drought from 2014 to 2017. Since traditional unilateral decision making processes to alleviate drought damage have, until now, resulted in conflicts between many of the involved groups, the need for active participation from both stakeholders and policymakers is greater than before. This study introduced Shared Vision Planning, a collaborative decision making process that involves participation from various groups of stakeholders, by organizing Water Policy Council for Climate Change Adaptation in Chungcheongnam-do. A Shared Vision Planning Model was then developed with a system dynamics software by working together with relevant stakeholders to actively reflect their requests through three council meetings. Multiple simulations that included various future climate change scenarios were conducted, and future drought vulnerability analysis results of Boryeong Dam and districts, in terms of frequency, length, and magnitude, were arrived at. It was concluded that Boryeong Dam was more vulnerable to future droughts than the eight districts. While the total water deficit in the eight districts was not so significant, their water deficit in terms of spatial discordance was proved to be more problematic. In the future, possible alternatives to the model will be implemented so that stakeholders can use it to agree on a policy for possible conflict resolutions.

The study showed that directional Shared Leadership and transformational Shared Leadership positively influences the relationship between Shared Leadership and interpersonal relationships in the view of organizational wellbeing. In addition, in the relationship between Shared Leadership and rewarding job experience of organizational wellbeing, three leadership types excluding directional Shared Leadership had positive effects. In addition, transformational Shared Leadership and empowering Shared Leadership had a positive impact on the relationship between Shared Leadership and organizational mood of organizational wellbeing. In the relationship between Shared Leadership and a sense of fulfillment in the view of organizational wellbeing, transformational Shared Leadership only had a positive effect. As is the case with the sense of fulfillment, the transformational Shared Leadership, of and itself, positively influenced the relationship between Shared Leadership and leisure of life of organizational wellbeing. A analysis of the study showed that transformational Shared Leadership has an impact on both organizational wellbeing and personal wellbeing. Transformational Shared Leadership helps set up mutual vision or strategies, or to challenge each other to enhance existing processes and procedures. On the other hand, directional Shared Leadership influences the interpersonal relations only, whereas transactional Shared Leadership impacts rewarding job experience only. Presenting clearer ideas on what to do to each other and sharing the reward for performance implies that the members of an organization can feel much more rewarded through job engagement.

Stereo vision has become an important technical issue in the field of 3D imaging, machine vision, robotics, image analysis, and so on. The depth map extraction from stereo video is a key technology of stereoscopic 3D video requiring stereo correspondence algorithms. This is the matching process of the similarity measure for each disparity value, followed by an aggregation and optimization step. Since it requires a lot of computational power, there are significant speed-performance advantages when exploiting parallel processing available on processors. In this situation, multi-core CPU may allow many parallel programming technologies to be realized in users computing devices. This paper proposes parallel implementations for calculating disparity map using a shared memory programming and exploiting the streaming SIMD extension technology. By doing so, we can take advantage both of the hardware and software features of multi-core processor. For the performance evaluation, we implemented a parallel SAD algorithm with OpenMP and SSE2. Their processing speeds are compared with non parallel version on stereoscopic streaming video. The experimental results show that both technologies have a significant effect on the performance and achieve great improvements on processing speed.

Recently we have developed an active stereo head-eye system with vergence, name it KIST HECter(Head-Eye System with Colored Stero Vision), based on the analysis of human's neck and eye motion at visual behavior. Our HECter is a five degree-of-freedom system composed of pan and tilt motion in neck part and independent vergence motion of binocular cameras and commonly shared elevation axis in eye part. And stereo vision Provides two color image, which are processed by powerful each TMS32080 vision board. The shape and size are designed to be almost same as human face. The ability to vergence has significant importance and gives many beneficial merits. On its mechanical implementation we adapt a non-parallelogram 4-bar linkage mechanism since it provides high accuracy in transfering motion and enables compact and flexible design.

Researchers indicates several issues as to performance evaluation methods for public health centers. Firstly, health centers are passively involved in the evaluation process, the performance indicators are activity-oriented, and mostly unrealistic. Balanced Scorecard is one of the methods for evaluating organizational performance, which is utilized at current in many industries including public sector. The purposes of this study is to apply balanced scorecard approach to a public health center and to develop performance indicators as well as their vision and strategies. For developing performance indicators, researchers selected K City Public Health Center and implemented brainstorming with members of health promotion team. Through team process they suggested goals, strategies and several indicators they considered proper to accomplish their shared vision. And then appropriateness of the indicators were evaluated by professional researchers in health promotion field for consensus building by email questionnaire. Based on survey and professional consensus meeting, 11 performance indicators were tailored in four perspectives as well as 6 strategies and 10 strategic goals, which are steps for accomplishing shared vision of health promotion team. For details, refer to the paper. Most members of health promotion team were satisfied with the indicators. However issues such as low level of recognition and familiarity with a new concept of BSC, and cultural resistance to strategic approach in public organizations should be addressed for future application and dissemination of BSC technique to public health organizations.

The major characteristic of open source software (OSS) is innovativeness. Innovativeness stems from the process of sharing and solving technical problems. This study analyzes the impact of voluntary participation and collaboration of OSS developers on sustained participation in the community based on organizational citizenship behavior and social capital theories. Based on Bolino et al. (2002) and Wasko and Faraj (2005), a research model and hypotheses are developed. A total of 152 OSS developers participated in the survey. The hypotheses are tested by LISREL modeling. The results of analysis show that royalty, social participation, and advocacy participation enhance or positively influence social capital. In addition, reciprocity and shared vision reinforce intention of sustained knowledge contribution. However, the result shows a statistically insignificant relationship between social participation and shared vision and between cohesiveness and intention of sustained knowledge contribution.

Visual cryptography is a scheme that recovers secret image through human vision by overlapping distributed share images without cryptographic operations. Distribution methods are still being developed for improving quality of shared images keeping size of images invariant and enhancing robustness against resize of images. Since visual cryptography only uses shared images, this fact is exploited to attack. From this fact, a scheme safe for sharing distributed images is needed. In this paper, a new visual cryptographic scheme using cover image is proposed. This scheme reduces the chance of detection against steganalysis and increases security. In addition, this paper shows that the proposed scheme can completely decrypt secret image without creating noise.
