The telemetry data received from satellite in real-time are used to monitor LEO satellite during the AIT (Assembly, Integration & Test) phase and the mission operation phase after launch. However, it is impossible to check all the incoming telemetry data from satellite in real time in order to detect abnormality of satellite quickly. Especially, the contact time of LEO satellite is limited because of its orbital characteristics. So the anomaly state of the LEO satellite should be detected and resolved during the contact time. Therefore, all incoming spacecraft telemetry data must be selected and manipulated in MIMIC. It is used in order to display summarized information about spacecraft in a visualized way that is quickly and easily understood. That is, it provides essential function to monitor a satellite both in orbit and during testing. In this paper, the design and development of MIMIC currently used in KOMPSAT, a LEO Earth observation satellite is described in detail. In future work, we plan to enhance MIMIC in order to improve user-friendliness and efficiency.

To study and validate tissue-specific promoters and vectors, it is important to develop cell culture systems that retain the tissue and species specificity. Such systems are attractive alternatives to transgenic animal models. This study established a line of porcine mammary gland epithelial cells (PMECs) from a primary culture based on the cellular morphology and mRNA levels of porcine beta-casein (CSN2). The selected PMECs were stained with the cytokeratin antibody, and were shown to express milk protein genes (CSN2, lactoferrin, and whey acidic protein). In addition, to confirm the acini structure of PMEC932-7 in 3D culture, live cells were stained with SYTO-13 dye, which binds to nucleic acid. The acini of these PMECs on matrigel were formed by the aggregation of peripheral cells and featured a hollow lumens. The system was demonstrated by testing the effects of the culture conditions to cell culture including cell density and matrigel methods of the PMECs. These results suggest that PMECs possess the genetic and structural features of mammary epithelial cells.

Complexity and Massive is the modem trend of construction project. The lack of timely and accurate construction data is the main cause for the lack productivity increases seen in other industries. Because information is essential in the construction production process, the lack of it will cause workers to stay idle, build the wrong thing that has to be redone, become involved in an accident or simply waste their time doing non-productive work. To aid construction automation and improve its productivity, RFID technology system should be developed. As a result of that, this study analyzes the status of RFID technologies in construction project and suggest advanced construction method. USN and RTLS system is analyzed in this study RFID system also can be used in construction management, material management, quality control, safety management and human resource management.

Recently, the advent of World-Wide-Web(WWW) and the explosive popularity of the Internet gave birth to collaborative applications which were enabled by computers and networks as their primary media. The progress of 3D computer graphics enabled collaborative application with 3D virtual environments or distributed virtual environments. In this paper, we explain our implementation of the Share collaboration engine which is for collaboration applications based on a distributed virtual environment. We introduce Virtual Architectural Engineering 2000 (VAE2000) that is our pilot application implemented with the Share collaboration engine. The Share collaboration engine proposes a new Share network architecture for management of participants, and it provides some synchronization methods for 3D objects in virtual collaboration. VAE2000 is an experimental application that tries to prevent wastes of human, material and time resources in networked virtual collaboration.

In the late 16th century, the Theatrum Anatomicum or anatomical theatre opened in Leiden in the Netherlands. The theatre was open to a fee-paying audience of students, surgeons, and the public and soon settled down as one of the highbrow cultural activities in the city. This trend soon spread into Amsterdam, and Nicholaes Tulp appearing in Rembrandt van Rijn's was at the center of it. Human anatomy was not just an eyesore but started to get accepted as a cultural event for the civilized citizens of the time. It was with this backdrop that Rembrandt got inspired by this interesting scene of Tulp dissecting human body. Rembrandt well understood the changes of the time and captured them on canvas to attempt convergence between science and art.

We conducted a nationalwide questionnaire to investigate accidental experiences and injuries at flashover or flame-fire for active firefighters in the line of duty. A total of 794 firefighters participated in this survey (764 males, 27 females, and 3 respondents; $39.2{\pm}8.4yr$ in age, $173.7{\pm}5.1cm$ in height, $73.4{\pm}8.6kg$ in body mass). The results showed that high risk circumstances the most frequently experienced while firefighting in Korea was flashover followed by backdraft, rollover and flameover. At the high risk circumstances the most frequently-experienced injuries were bruise, stabs and burns. Firefighters hoped to reduce the total mass of personal protective equipment (PPE), improve the mobility of the PPE and dexterity of protective gloves, so that they could escape from the high risk circumstances as fast as possible. In particular, requirements for improvement on protective gloves were greater than those on other PPE. The present study suggested that the need for improvements on the current firefighters' PPE to cope with emergency high risk situations in terms of PPE mass reduction and mobility.

In contrast to the short-term nature of lunar missions in the past, lunar missions in new space era aim to extend the presence on the lunar surface and to use this capability for the Mars exploration. In order to realize extended human presence on the Moon, production and use of consumables and fuels required for the habitation and transportation using in-situ resources is an important prerequisite. The Global Exploration Roadmap presented by the International Space Exploration Coordination Group (ISECG), which reflects the space exploration plans of participating countries, shows the phases of progress from lunar surface exploration to Mars exploration and relates in-situ resource utilization (ISRU) capabilities to each phase. Based on the ISRU Gap Assessment Report from the ISECG, ISRU technology is categorized into in-situ propellant and consumable production, in-situ construction, in-space manufacturing, and related areas such as storage and utilization of products, power systems required for resource utilization. Among the lunar resources, leading countries have prioritized the utilization of ice water existing in the permanent shadow region near the lunar poles and the extraction of oxygen from the regolith, and are preparing to investigate the distribution of resources and ice water near the lunar south pole through unmanned landing missions. Resource utilization technologies such as producing hydrogen and oxygen from water by hydroelectrolysis and extracting oxygen from the lunar regolith are being developed and tested in relevant lunar surface analogue environments. It is also observed that each government emphasizes the use and development of the private sector capabilities for sustainable lunar surface exploration by purchasing lunar landing services and providing opportunities to participate in resource exploration and material extraction.
