The molecular markers to distinguish different larval stages have various applications in ecological studies. Using the differential display RT-PCR technique, we isolated and characterized four genes, which are expressed predominantly in the megalopa stage of Eriocheir sinensis. The four genes include two cuticular proteins with different domain organization (Ers-CP15 and Ers-CP34) and two skeletal-muscle-specific genes (Ers-SCP and Ers-ActinSK1). The two cuticular protein genes were expressed predominantly in the epidermis and their expression level was significantly higher in the megalopa stage (about 7.0-folds) than it was in the zoea stage. However, their high transcriptional level in zoea IV suggested that these two cuticular protein genes may not be a useful target to discriminate megalopa from zoea. Ers-SCP encoded the invertebratespecific sarcoplasmic calcium binding protein and Ers-ActinSK1 gene encoded the crustacean skeletal muscle actin. Expressions of these two genes were detected only in muscular tissues; leg muscle, claw muscle and thoracic muscle. This suggests that the increased transcription levels of two muscle-specific genes during the megalopa stage are mainly due to increased muscular tissues. Among its three isoforms, Ers-SCPa displayed the highest difference (22.4-folds) between megalopa and zoea suggesting Ers-SCPa is the most reliable marker to distinguish megalopa from zoea. Although Ers-SCPc and Ers-ActinSK1 also showed similar expression profiles to Ers-SCPa and Ers-SCPb, differences in their expression levels were not as high as Ers-SCPa and Ers-SCPb.

Security and monitoring system has many applications and commonly used for detection, warning, alarm, etc. As the networking technology advances, user requirements are getting higher. An intelligent and cooperative surveillance system is proposed to meet current user demands and improve the performance. This paper focuses on the implementation issue for the embedded intelligent surveillance system. To cover wide area cooperative function is implemented and connected by wireless sensor network technology. Also to improve the performance lots of sensors are employed into the surveillance system to reduce the error but improve the detection probability. The proposed surveillance system is composed of vision sensor (camera), mic array sensor, PIR sensor, etc. Between the sensors, data is transferred by IEEE 802.11s or Zigbee protocol. We deployed a private network for the sensors and multiple gateways for better data throughput. The developed system is targeted to the traffic accident detection and alarm. However, its application can be easily changed to others by just changing software algorithm in a DSP chip.

Background Classical flaps for perinasal defect reconstruction, such as forehead or nasolabial flaps, have some disadvantages involving limitations of the arc of rotation and two stages of surgery. However, a perforator-based flap is more versatile and allows freedom in flap design. We introduced our experience with reconstruction using a facial artery perforator-based propeller flap on the perinasal area. We describe the surgical differences between different defect subtypes. Methods Between December 2005 and August 2013, 10 patients underwent perinasal reconstruction in which a facial artery perforator-based flap was used. We divided the perinasal defects into types A and B, according to location. The operative results, including flap size, arc of rotation, complications, and characteristics of the perforator were evaluated by retrospective chart review and photographic evaluation. Results Eight patients were male and 2 patients were female. Their mean age was 61 years (range, 35-75 years). The size of the flap ranged from 1 cm×1.5 cm to 3 cm×6 cm. Eight patients healed uneventfully, but 2 patients presented with mild flap congestion. However, these 2 patients healed by conservative management without any additional surgery. All of the flaps survived completely with aesthetically pleasing results. Conclusions The facial artery perforator-based flap allowed for versatile customized flaps, and the donor site scar was concealed using the natural nasolabial fold.

Since the introduction of mandatory health insurance in 1977, the Korean national health insurance(KNHI) has grown rapidly. In 2004, about 96.9% of the total population are covered by the KNHI and the remaining 3.1% by the Medical Aid program. Despite national health insurance system in Korea, private health insurance market has grown rapidly. In 2004, the size of the private health insurance market was estimated at 6,568 billion won. The purpose of this study is to identify the factors that determine the purchasing decisions of supplementary private health insurance under mandatory national health insurance system in Korea. The data from 2004 Busan Health Survey were analysed for the purpose. The variables in this study are demographic factors, health status and health behavioral factors, health care systemic factors, and socioeconomic factors. For statistical analyse, we used logistic regression. The Findings show that female, economically active age group(especially 35-49 years), persons with better health status or experience of health screening test are more likely to purchase private health insurance. And higher household income and expenditure, higher education level are more associated with the increased probabilities of private health insurance purchases. This results imply that the expanding of private health insurance market could widen the gap between the have and have-not in terms of equal health care accessibility.

In the present, Wireless Sensor Network(WSN) has been used for the purpose of the military operation with surveillance systems and for collecting useful information from the natural environment. Basically, low-power, easy deployment and low cost are the most important factors to be deployed for WSNs. Lots of researches have been studied to meet those requirements, especially on the node capacity and battery lifetime improvements. Recently, the study of wireless mesh networks applied into the surveillance systems has been proceeded as a solution of easy deployment. In this paper, we proposed large-scale intelligent multi-layer surveillance systems based on QoS assuring Wireless Mesh Networks and implemented them in the real testbed environment. The proposed system explains functions and operations for each subsystem as well as S/W and H/W architectures. Experimental results are shown for the implemented subsystems and the performance is satisfactory for the surveillance system. We can identify the possibility of the implemented multi-layer surveillance system to be used in practice.

The purpose of this study is to suggest the direction of development in architectural technology far designing intelligent future housing. Recently, intelligent housing was built by several countries such as England, France, America and Japan and it was constructed by major construction companies in Korea, also. However, design direction of intelligent housing has not completed until now and intelligent housing have been constructed without specific direction have caused to unreasonable economical investment, commercializing of intelligent system, environmentally-unfriendly problems. Based of these problems, it is important that the direction of development in architectural technology for designing intelligent housing has been studied through the research. In this research, three intelligent housing cases built by major constnzction companies in Korea, are analyzed and the direction of development in architectural technology for designing intelligent future housing, are suggested through the research.
