Recently many new subway lines and light rail lines are demanded to build as CBTC system for advanced transportation needs. Already several lines are being installed and some other are planned this days. In early 2008, the first korean CBTC project, Bundang Line Intelligent Train Control System was finished successfully then it showed that many advantage of its functionalities to demonstrate. Nowaday, the technology of CBTC in Korea is not standing alone by itself yet, even though a lot of localization was done last decade include ATS (Automatic Train Supervision) and Radio Communication and manufactures and installations, because the core equipment of CBTC is rely on oversea technologies of major railway signal companies. KRRI has been preparing to develop the core equipment of CBTC (wayside ATP and onboard ATO/ATP) with other 14 local railway signal companies. Now they have consisted two consortiums to develop the core equipment by themselves. In this paper, I will mention about how we should focus on the output for viewpoint of interpretabilities between the two groups and review the case study of front developers efforts considering to standardizations we should be following.

This paper presents a low cost hardware message passing engine of enhanced atomic pipelined broadcast based on processing node status. In this algorithm, the previous atomic pipelined broadcast algorithm is modified to reduce the waiting time until next broadcast communication. For this, the processor change the transmission order of processing nodes based on the nodes' communication channel. Also, the hardware message passing engine architecture of the proposed algorithm is modified to be adopted to multi-core processor. The synthesized logic area of the proposed hardware message passing engine was reduced by about 16%, compared by the pre-existing hardware message passing engine.

This article focuses on the image of the ancestor of Quanzhen Daoism from a narrative perspective and also evaluates the influence of this image on the development of Quanzhen Daoism in terms of belief, genealogy, and the compilation of sacred history. Quanzhen Daoism has a rich tradition of narrating andwriting its history. In fact, narrating history is actually a form of constructing history. From the recounting of events such as the birth of the founder of the religion, Wang Chongyang (王重陽, 1112-1170), his conversion to Daoism, his practice and preaching, and his 'ascent to immortality' in Quanzhen historical hagiographies, readers can observe the recording of miracles as a narrative feature. The narratives of religious texts differ from ordinary historical narratives in that the former maintain the core concern of simultaneously promoting belief in miracles and strengthening the religious lineage of the respective tradition. Therefore, exploring the relationship between the narrative of the image of the ancestor and the development of the Quanzhen Sect, along with the establishment of beliefs, is the starting point of this article.

As content providers further offload content-centric services to the cloud, data retrieval over the cloud typically results in many redundant items because there is a prevalent near-duplication of content on the Internet. Simply fetching all data from the cloud severely degrades efficiency in terms of resource utilization and bandwidth, and data can be encrypted by multiple content providers under different keys to preserve privacy. Thus, locating near-duplicate data in a privacy-preserving way is highly dependent on the ability to deduplicate redundant search results and returns best matches without decrypting data. To this end, we propose an efficient near-duplicate detection scheme for encrypted data in the cloud. Our scheme has the following benefits. First, a single query is enough to locate near-duplicate data even if they are encrypted under different keys of multiple content providers. Second, storage, computation and communication costs are alleviated compared to existing schemes, while achieving the same level of search accuracy. Third, scalability is significantly improved as a result of a novel and efficient two-round detection to locate near-duplicate candidates over large quantities of data in the cloud. An experimental analysis with real-world data demonstrates the applicability of the proposed scheme to a practical cloud system. Last, the proposed scheme is an average of 70.6% faster than an existing scheme.

This paper presents a high sensitive force sensing module to measure machining forces for a tip-based nanopatterning instrument. The force sensing module utilizing a leaf spring mechanism and a capacitive displacement sensor has been designed to provide a measuring range from 80$\mu$N to 8N. This force sensing module is mounted on a PZT driven in-feed motion stage with 1 nm resolution. The sample can be moved by a X-Y scanning motion stage with 5 nm resolution. In the patterning experiments, the machining forces were controlled and monitored by the force sensing module. Then, the patterned sample was measured by AFM. Experimental results demonstrated that the developed force sensing module can be used as an effective sensing device in the nanopatterning operation.

Ozone measurements made from 4 sites in Jeju Island have been analyzed, including those from two urban and two rural locales. The data were analyzed in terms of the seasonal and diurnal trends. It should be clear that the surface ozone levels in Jeju area would be relatively sensitive to the external ozone supply originated from the region of Northeast Asia. It seems to be that due to the reactions of ozone with $NO_{x}$ and CO, the average ozone level in Jeju City appears lower than that in Seogwipo City although Jeju City is the largest city in Jeju Island.

This paper investigates the performance of an electromagnetic type active control engine mount (ACM) recently developed in the laboratory. The ACM employs the basic structure of the conventional hydraulic engine mount of which upper chamber is connected to a dual magnet electromagnetic actuator. The actuator, that essentially replaces the existing decoupler of the conventional passive hydraulic engine mount, actively controls the upper chamber pressure. Using the linearized ACM model incorporated with the actuator dynamics, we suggest an optimal design of ACM, maximizing the actuator efficiency as well as the vibration isolation efficiency.

Unmanned aerial vehicles (UAVs) are a popular research topic because of a great ripple effect in the future. However, current UAV technologies cannot be applied to manual aerial vehicles without any modification. As an alternative to current UAV technology, humanoid robots are adopted as pilots. If a humanoid robot controls an aerial vehicle autonomously, not only could manual aerial vehicles be utilized as UAVs, but the humanoid robot would also be put into an environment created for humans and conduct some missions suitable for humans. Humanoid robots are also able to handle tools and equipment designed for humans. In order to prove that a humanoid robot can pilot an airplane, an experiment is performed and the results of this experiment are shown in this paper.

One of different methods to increase the productivity of software development team is to reuse the software components which were used once. Such a reusable software components are often organized software libraries. In order to reuse effectively the software modules selected from a library, the users need information enough to search for the modules easily. This paper designs and implements the tool which provides the information about the relationship between classes to reuse software components, and makes a new class by combining the data and functions from existing classes.
