DNS는 인터넷주소 자원관리의 핵심이며 가장 기본이 되는 네이밍 서비스를 제공한다. 현재의 DNS는 트리구조로 계층화 되어있다. 하지만, 상위 DNS의 장애발생으로 인한 하위 DNS는 정상적인 연결이 어렵게 되며, 보조 DNS를 운영한다고 하더라도 그 위험성은 여전히 존재하게 된다. DNS는 빠른 검색이 가능하다는 장점 때문에 지금의 계층 구조를 버릴 순 없다. 본 논문에서는 이와 같은 DNS 장애 발생 시 효율적으로 대처할 수 있도록 지금의 계층구조의 장점을 유지하고 수평적이면서 독립적인 DNS구조를 추가해서 장애가 발생하더라도 임시적으로 로컬 DNS의 운영이 가능하도록 하였다.

Objectives: The objective of this study is to identify the gender differences of risk factors for falls among the elderly in community dwellings. Methods: We analyzed the data on 3,278(male 1,255, female 2,023) persons, including 497 persons who have experienced falls, drawn from the 2004 National Elderly Survey. We conducted a cross-tabulation analysis, $X^2$-test and hierarchical regression analysis of the impact of the socio-economical characteristics, environmental characteristics, the number of chronic diseases, usage of supplementary devices, activities of daily living, dementia, and the severity of problem behavior. Results: For the entire sample of the elderly, gender, age, the size of the cities of residence, the number of chronic diseases, and the severity of problem behavior were identified as risk factors for falls. The number of chronic diseases and the severity of problem behavior were found to be significant for the male subsample, while age, the size of cities of residence, dwelling types, and the number of chronic diseases were found to be significant for the female subsample. Conclusion: The number of chronic diseases was identified as a common risk factor for falls in the male and female elderly. Chronic diseases were also found to aggravate the risk for falls when they concur with other diseases.

The 4-th generation of mobile communication aims to realize global, fast and mobile communication service. The satellite communication charges a key role in this field. In this study, an OTM(On-The-Move) antenna which is mounted on ground vehicles and is used for mobile communication between vehicle and satellite was addressed. Since vehicles move during communication, active antenna line-of-sight stabilization is a core technology to guarantee high satellite communication quality. Stabilization of a satellite tracking antenna which consists of 2-DOF gimbals, an elevation gimbal over an azimuth gimbal, was considered in this study. Various disturbance torques such as static and dynamic mass imbalance torques, variation of moment of inertia according to elevation angle, friction torque related to vehicle motion, equivalent disturbance torque due to antenna roll motion, etc. were analyzed. As a robust stabilization control, rate feedback with sliding mode control and position feedback with proportional+integral control was suggested. To compensate antenna roll motion, a supplementary roll rate feed forward control was included beside of the feedback control loop. The feasibility of the analysis and the proposed control design were verified along with some simulation results.

Background and Purpose: To explore anatomic substrate of specific wandering patterns in patients with Alzheimer's disease (AD) by performing positron emission tomography with $^{18}F$ fluorodeoxyglucose positron emission tomography (FDG PET). Methods: Drug-naïve AD patients with wandering (n=80) and without wandering (n=262) were recruited. First, the specific pattern of wandering type was operationally classified according to specific wandering score and clinical assessment. Second, brain FDG PET was performed and fluorodeoxyglucose (FDG) uptake differences of specific brain regions according to wandering patterns were compared to those of non-wanderers. Results: In patients with pacing pattern, FDG PET showed significant lower FDG uptake in both middle cingulum and left putamen cluster compared to non-wanderers. The right precuneus and supplementary motor area in patients with random pattern and left calcarine sulcus, right calcarine sulcus, right middle cingulum, and right post central gyrus in patients with lapping pattern had significantly lower FDG uptake compared to non-wanderers. Conclusions: This study showed that wandering in patients with AD had three distinct patterns. These specific patterns showed significant lower FDG uptake in specific brain areas compared to non-wanderers.

Purpose: The research is to find out the perception of consumers for the convenience store (c - store) image in an emerging market, with a sample from Ho Chi Minh City. Research design, data, and methodology: Data were collected using a 24 - item structured questionnaire into six factors, namely: store atmospheric, merchandise, supplementary service, customer convenience, sales personnel, promotion. Five hundred consumers shopped at the different c - stores were collected for a multidimensional scaling technique that creates a perceptual map illustrating of c - store image. Results: The results point out that consumers' perception of a different c - store is different. The trend of c- stores are focusing on the dimensions of the function aspect. The customers also put their attention on the psychological dimension, which, in this case, is customer convenience with a sharp point. Almost all stores are bad on store atmospheric in customer- based. Conclusions: The modern retail store chains need to focus on elements to create a store image positioning and improve the perceptions of the consumers towards the store. Besides, customers not only visit the stores, not due to its convenient location, mass media or shopping experience, but also a strong identity for the store's brand image.
