In this study, we aim to understand how social computing features affect open source project's outcome based on the representative social coding platform, Github (http://github.com). Though there is growing interest regarding the application and effect of employing social computing features, yet empirical evidences related to the subject are still short. To bridge the gap, we conducted our research based on the following research questions: 1) How the system features of social coding platform are classified? 2) How are the use of system features and project performance related to each other? Qualitative and quantitative analysis are performed: The system features of Github are clustered according to their usage in qualitative analysis, and th relation between the feature uses and project outcome is identified by multiple linear regression test. In conclusion, we found that the use of results is also discussed.

In order to mitigate the overcapacity of Busan port, Busan new port has been developed as transshipment port which is capable of handling 8,000 TEU containership. Generally, design of transshipment port has to reflect the capacity of feeder because both mother vessels and feeders enter the planned port at the same time. However, the existing plan of Busan new port capacity needs to be reexamined since the adopted capacity of each berth at new port, 300,000 TEU, does not seem to be enough to handle both mother vessels and feeders. Therefore, in this study we calculated the required number of berth and berth length by considering cargo handling capacity in terms of the ship size and this study makes some implications in relation with the terminal development plan.

In this paper, we analyse empirically the relation between the IT competency of the Group enterprises, and the management performance of the subsidiary IT service firms in Korea. The 24 IT service firms and relative Group enterprises are included for analysis. The various hypotheses established are validated by t-test method statistically. The results shows that IT competency level of the Group enterprises was affected by not only their sales volumes, new investment volume of IT service, but system management(SM) and inner captive market's sales volume of subsidiary IT service firms also. Additionally the sales volume of IT service firms was affected positively by their inner-captive market's sales, system management sales volume, and the sales volume of their Group enterprise. The service competency of the subsidiary IT service firms is shown as more high in the lower intensity of outer-captive and system integration(SI) business, as well as in the upper intensity of inner-captive and SI business.

The Baroque style expressed in the 17th century costume offered a dynamic feeling through wavy curves, and its brilliant and colorful decorations created a passionate and charming mood resembling a flame. Accordingly, this research studied the body image as it appeared in the form of 17th century western men's costume by dividing it into the contact beauty of the human body and the manner of hiding the architectural beauty of the human body. First, the exposed silhouette by clothing coming into contact with the human body could be found mainly in upper-class men's costume in the first half of the 17th century. The shorter and tighter doublets and knee breeches could be analyzed in terms of erotic imagery that emphasized masculinity, aristocratic imagery that stressed a distinctive status, and geometric imagery that expressed a triangular pattern. Second, the constructive expression by hiding the human body could be found in upper-class men's costume starting in the mid-17 century. The wearing of the justaucorps could be studied in terms of how it came into contact with the beauty of the human body but also how this clothing style the hid the architectural beauty of human body.

Due to the increase in size of the computer network, the network security systems such as a firewall, IDS, IPS generate much more vast amount of information related to network security. So detecting signs of hidden security threats has become more difficult. Security personnels' 'Network Security Situational Awareness(NSSA)' is effectively determining the security situation of overall computer network on the basis of the relation between the security events that occur in the several views. The process of situational awareness is divided into three stages of the 'identification,' 'understanding' and 'prediction'. And 'identification' and 'understanding' are prerequisites for 'predicting' and the following appropriate responses. But 'identification' and 'understanding' in the vast amount of information became more difficult. In this paper, we propose Honeycomb security situational awareness visualization system that is designed to help NSSA in large-scale networks by using visualization techniques known effective to the 'identification' and 'understanding' stages. And we identified the empirical effects of this system on the basis of the 'VAST Challenge 2012' data.
