iATA(Internet Advanced Technology Attachment)는 TCP/IP 네트워크를 통해 원격의 대용량의 가상 저장 공간을 자신의 로컬 디스크 처럼 활용이 가능하게 하는 기술로 이는 모바일 기기(PDA, 휴대폰 등)와 같은 저장 공간의 부족문제를 가지고 있는 장치에 적용하여 저장 공간의 부족 문제를 근본적으로 해결할 수 있는 솔루션이라 할 수 있다. iATA는 SCSI 하드디스크가 장착된 시스템에서만 서버를 구축해야만 하는 iSCSI와는 달리 일반 가정이나 사무실에서 주로 사용하는 ATA 하드 디스크에도 서버 구축이 가능한 확장성을 가지고 있으며 이는 iATA의 최대 장점 중 하나라 할 수 있다. 또한, Web 사이트를 통해 많은 사람들이 iATA 서비스를 이용하여 자신의 모바일 기기에서의 저장공간 문제를 극복할 수 있으며, 최근 사회 문제로 크게 대두되고 있는 개인 정보 유출의 폐해를 막기 위해 개인 인증시 OpenSSL과 MD5를 이용한 보안/암호화 기법을 사용하여 개인 정보 유출에 의한 불이익 및 개인 정보 악용으로 인한 범죄를 막을 수 있다. 하지만, 기존의 iATA상에서는 디스크 관리가 서버에서만 가능하다는 문제점이 있다. 즉, 사용자만의 개인공간을 가질 수가 없다. 이처럼 개인 사진이나, 다이어리같은 정보들을 관리 할 수 없는 문제점을 해결하기 위해 클라이언트에서 자신만의 디스크 공간을 가질 수 있게 파티션을 할당해주고, 그 공간을 클라이언트만의 공간으로 만들어 주는 기술을 개발하는데 그 목적이 있다.

Purpose: The aim of this study was to examine the effects of a music-based group reminiscence program on interpersonal relationships, self-esteem and depression in elderly people who are hospitalized. Methods: A quasi-experimental research was implemented, and a nonequivalent control group pre-posttest design was used. The participants were 52 elders who met the selection criteria and were assigned to the experimental group (26) and the control group (26). Both groups took the pre and posttest at the same time, and both groups received regular hospital care with the experimental group participating in the program for 12 sessions over six weeks. The instruments used in the study were, for interpersonal relationships, the Interpersonal Change Scale by Schlein and Guerney (1971), for self-esteem, the Self-Esteem Scale by Rosenberg (1965) and for depression, the Depression Inventory by Zung (1965). The collected data were analyzed with the SPSS 15.0 program. Results: Compared to the control group, the experimental group had significantly better interpersonal relationships and significantly higher self-esteem and less depression. Conclusion: The findings of the study suggest that a music-based group reminiscence program is effective in improving the interpersonal relationships, self-esteem and depression of hospitalized elders.

Visibility of the road influence the safe driving because it recognizes the obstacle on the road. In this paper, we propose a mobile data acquisition and processing system for evaluating road visibility at night. And it was converted efficiently with mobile images and archived for spatial analysis of road-visibilities at night. This was applied to the following techniques to the system. Low-power computing units, open an image processing library, GPU-based acceleration techniques and document database techniques, etc. And converting the RGB image to the YUV color system, which was integrated the brightness component and the spatial information. High performance Android devices were used to collect brightness data on roads and it was confirmed whether this prototype was to determine the spatial distribution of such acquisition and management systems for spatial-assessments of road visibility at night.

This paper describes a method that can be used for estimating future carbon emissions and environmental effects. To forecast future land use and transportation changes under various low carbon policies, a DELTA and OmniTRANS combination (a land use-transport integrated model) was applied. Appropriate emission estimation methods and dispersion models were selected and applied in the method. It was designed that the estimated emissions from land use and transportation activity as well as the estimated concentrations of air pollutants and comprehensive air quality index (CAI) are presented on a GIS-based map. The prototype was developed for the city of Suwon and the outcome examples were presented in this paper; it demonstrates what kinds of analysis results are presented in this method. It is expected that the developed method will be very useful for decision makers who want to know the effect of environmental policies in cities.

Anabaena (Cyanobacteria, Nostocales) are important for water quality controls, because they are often responsible for freshwater green tides; moreover, some species are reported to produce hepatotoxin. In this study, we sequenced RNA polymerase beta subunit (rpoB) gene of Anabaena, and evaluated their sequences for the potential use of a molecular taxonomic marker in this taxon. Anabaena rpoB showed low DNA similarity and high genetic divergences when compared those of 16S rRNA, and the molecular differences were statistically significant (Student t-test, p<0.01). Parsimony analyses showed the rpoB gene evolves 4.8-fold faster than 16S rRNA. In addition, phylogeny of the rpoB gene separated each Anabaena strain more clearly compared with a 16S rRNA tree. These results suggest that the rpoB gene is a useful marker for the molecular phylogenetics and the species discrimination of Anabaena.

Objective : Zhang zhi-cong insisted the theory related to the 'Six-meridian qi transformation', and Zhen xiu-yuan inherited that theory understanding six-meridian disease of "Shang-Han-Lun". This emphasizes that the disease of 'three yin and three yang' in "Shang-Han-Lun" is a disease caused by Six-meridian qi transformation, not a lesion of meridian itself. He said, "If you do not know brightly in the 'Tip, Root and Middle qi', you can not read the "Shang-Han-Lun"." Therefore, in this paper, we examine the interpretation of the "Shang-Han-Lun"by using the theory of 'five circuits and six qi'. Method : First, extract sentences related to 'Tip, Root and Middle qi' from the sentences of "Shang-Han-Lun" Second, the sentence is interpreted through the Zhen xiu-yuan's "Sang han lun qian zhu". Third, the meaning of the sentence is examined and summarized. Result : Zhen xiu-yuan proposed a clear and systematic theory that can understand the meaning of Six-meridian in "Shang-Han-Lun", by utilizing the discipline that 'Tip, Root and Middle qi' Conclusion : The change of 'Tip, Root and Middle qi' is a very central theory that explains the properties of 'Yin and Yang' and mutual correspondence among Korean medicine theories. It also provides basic directions for understanding the changing patterns of disease.

PURPOSES : This study evaluates the reliability of the patterns of changes in the road surface temperature during winter using a statistical technique. In addition, a flexible road segmentation method is developed based on the collected road surface temperature data. METHODS : To collect and analyze the data, a thermal mapping system that could be attached to a survey vehicle along with various other sensors was employed. We first selected the test route based on the date and the weather and topographical conditions, since these factors affect the patterns of changes in the road surface temperature. Each route was surveyed a total of 10 times on a round-trip basis at the same times (5 AM to 6 AM). A correlation analysis was performed to identify whether the weather conditions reported for the survey dates were consistent with the actual conditions. In addition, we developed a method for dividing the road into sections based on the consecutive changes in the road surface temperature for use in future applications. Specifically, in this method, the road surface temperature data collected using the thermal mapping system was compared continuously with the average values for the various road sections, and the road was divided into sections based on the temperature. RESULTS : The results showed that the comparison of the reported and actual weather conditions and the standard deviation in the observed road surface temperatures could produce a good indicator of the reliability of the patterns of the changes in the road surface temperature. CONCLUSIONS : This research shows how road surface temperature data can be evaluated using a statistical technique. It also confirms that roads should be segmented based on the changes in the temperature and not using a uniform segmentation method.
