Selectivity estimation is one of the query optimization techniques. It is difficult for the previous selectivity estimation techniques for moving objects to apply the position change of moving objects to synopsis. Therefore, they result in much error when estimating selectivity for queries, because they are based on the extended spatial synopsis which does not consider the property of the moving objects. In order to reduce the estimation error, the existing techniques should often rebuild the synopsis. Consequently problem occurs, that is, the whole database should be read frequently. In this paper, we proposed a moving object histogram method based on quad tree to develop a selectivity estimation technique for moving object queries. We then analyzed the performance of the proposed method through the implementation and evaluation of the proposed method. Our method can be used in various location management systems such as vehicle location tracking systems, location based services, telematics services, emergency rescue service, etc in which the location information of moving objects changes over time.

In this study, we tried to offer the possibility of White Hibiscus syriacus L. (WHS) flower extracts as a preventive and improving agent of osteoporosis that bone mass reduction is induced by an decrease of osteoblast involved in bone formation and increase of bone resorption by osteoclast activity. As a results, it was found to have antioxidant activity and contain a flavonoid contents ($47.74 mg/g) of the WHS flower. There was cytotoxicity at more than $250{\mu}g/m{\ell}$ concentration of WHS flower extract of RANKL-induced osteoclast in RAW264.7. There were no significant inhibited TRAP activity in the WHS leaf and stem. However, it was confirmed that it is significantly inhibited the differentiation activity of osteoclasts in 50 and $100{\mu}g/m{\ell}$ concentration of cells of stability levels of only WHS flower extracts (p < 0.01). The WHS flower prominently inhibited RANKL-induced osteoclast differentiation activity by decreased calcitonin receptor and TRAP mRNA (p < 0.01). These results indicate that of osteoclasts differentiation activity is inhibited by protection of oxidative stress due to the antioxidant activity of the WHS flower. Therefore, suggesting the WHS flower may be a presents the possibility as a preventive and therapeutic agents for osteoporosis.

The Korean Military Satellite Communication System (KMILSATCOM) is composed of military payload of KOREASAT 5 and military satellite terminals. The military satellite terminals communicate with each other in satellite service area. The satellite terminal management system is developed for centralized management of satellite terminals and communications link. The satellite terminal management system dose not use terrestrial networks (i.e. Fiber optic, Microwave) for management because the KMILSATCOM is system for emergency (i.e. war time) and the satellite terminals has to move to operational area, so the management link must use satellite link. The management link is composed of 1 to N communication scheme for one manager and multiple terminals. This paper describes the satellite terminal management protocol architecture and the performance of the protocol of the KMILSATCOM system.

This study was carried out to provide basic data for the development of an educational program by assessing the its effects on the MDROs infection management performances of nurses at general hospitals. Data was obtained through a structured questionnaire survey conducted on 202 nurses. The average of knowledge score was 17.68 and their perceived susceptibility, perceived severity, perceived benefits, and performances had correlation. There was difference in their performances in accordance with their general characteristics including marriage, clinical experiences, positions, and affiliated department. Factors that affected MDROs infection management performance included perceived benefits and affiliated department with an explanation power of 35%. Therefore, it is necessary to emphasize the benefits by including advantages and effects of performing the MDROs infection control at the time of the development. In addition, nurses are required to have MDROs infection control education.

Recently, due to the climate change, the frequency and intensity of extreme rainfall events have been continuously increased in regions of South Korea. As a consequence, safety issues have been raised especially in the hydrologic safety of old dams designed and constructed by the old standards. In general, for improving hydrologic safety of existing dams, two options are considered: 1) raising dam crest; and 2) constructing or expanding an emergency spillway. In this process, the main criteria of alternative selection are overtopping possibility and cost efficiency of each alternative. This approach is easy to implement but it is subject to major limitation for the proper evaluation of alternatives, overlooking downstream flood damages by any controlled flow of water that is intentionally released from dams to eliminate the possibility of overtopping. Therefore, this study suggests a framework for evaluating the dam safety strengthening alternatives in terms of a comprehensive flood control by applying the concept of resilience. The case study shows that the resilience-based evaluation framework which considering downstream flood damages is effective in the selection of dam safety strengthening alternatives.

Purpose: The purpose was to investigate the factors influencing the alcohol consumption behavior of adolescents to provide basic data for a nursing intervention program to improve health management and prohibit alcohol consumption. Method: The subjects were 306 university students, living in K city in Chungnam province from April 1 to 20th, 2002. The instruments used were the alcohol consumption behavior scale, that is the drinking intensity score, and developed by Shin(1998)'s scale of drinking problem, refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman et. al. (1989), TPQ scale by Cloninger(1991), depression scale by Zung(1974), family cohesion scale by Olson et. al. (1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, t-test, ANOVA, and stepwise multiple regression by using SPSS & SAS program. Results: The multiple regression analysis revealed that the most powerful predictor of alcohol consumption behavior was the influence of friends (drinking everyday) (17.0%). A combination of alcohol expectancy (8.0%), influence of friends (4.0%), father's influence (2.0%), depression(2.0%), refusal self-efficacy (1.0%), personality of harm avoidance(1.0%), and monthly pocket money (2.0%) accounted for 38.6% of the variance in alcohol consumption behavior. Conclusion: From the results, we recommend to use the database that develops nursing intervention program for decreasing the alcohol consumption behavior including the influencing factors in university students.

Location-based services (LBS) are used in various applications such as emergency support, navigation, location, traffic routes, information gathering, and entertainment due to the rapid growth of information communication technologies and mobile phones. In general, locations are represented by coordinates and are related to terrain. These are of great interest in mobile-based data transmission. This paper proposes a method to exchange the contact of the other party by detecting the movement of the mobile phone of the individual user based on the location-based service. The proposed method extracts motion using the acceleration sensor of the mobile phone and transmits the location and time information to the server when the motion continues for a predetermined time. Attempts to establish a connection between users who are experiencing motion in mobile phones in the short distance have been made from the server. Once the connection between the users is made, the encrypted contact is received from the server. Experimental results show that the proposed method can exchange data by minimizing the processing in the handset compared with the existing method.
