  • The United Kingdom has a well-developed and comprehensive information infrastructure which has grown up over many years, but in the strict sense it has no coherent body of policy relating to information collection, storage, provision and supply. However, each of the governmental, professional and other bodies which has any major involvement with information, has committees to run its affairs and develop its policies in relation to issues and problems in the field. In addition, a number of ad hoc committees and working parties, to discuss or deal with a current problem, or to monitor or advise on the conduct of a research or development project, show that there is a high degree of awareness. of what is happening in the field and that there are many opportunities for expressing any particular point of view. The need for good intelligence in business or industrial operations is now being more generally accepted, and in consequence the need for a director of intelligence is also seen. The director of information in an industrial setting is the information manager, who combines or has access to the skills of several disciplines, including library, data processing and communication skills as well as managerial. Recognition of the need for such persons has policy implications in terms of short-term training provision and long-term educational facilities for the emerging profession, as well as manpower planning implications.

  • As the technology in smart device is growing and Social Network Services(SNS) are becoming more common, the data which is difficult to be processed by existing RDBMS are increasing. As a result of this, NoSQL databases are getting popular as an alternative for processing massive and unstructured data generated in real time. The demand for the technique of digital investigation of NoSQL databases is increasing as the businesses introducing NoSQL database in their system are increasing, although the technique of digital investigation of databases has been researched centered on RDMBS. New techniques of digital forensic investigation are needed as NoSQL Database has no schema to normalize and the storage method differs depending on the type of database and operation environment. Research on document-based database of NoSQL has been done but it is not applicable as itself to other types of NoSQL Database. Therefore, the way of operation and data model, grasp of operation environment, collection and analysis of artifacts and recovery technique of deleted data in HBase which is a NoSQL column-based database are presented in this paper. Also the proposed technique of digital forensic investigation to HBase is verified by an experimental scenario.

  • Origin-destination data have been collected and utilized for demand analysis and service design in various fields such as public transportation and traffic operation. As the utilization of big data becomes important, there are increasing needs to store raw origin-destination data for big data analysis. However, it is not practical to store and analyze the raw data for a long period of time since the size of the data increases by the power of the number of the collection points. To overcome this storage limitation and long-period pattern analysis, this study proposes a methodology for compression and origin-destination data analysis with the compressed data. The proposed methodology is applied to public transit data of Sejong and Seoul. We first measure the reconstruction error and the data size for each truncated matrix. Then, to determine a range of principal components for removing random data, we measure the level of the regularity based on covariance coefficients of the demand data reconstructed with each range of principal components. Based on the distribution of the covariance coefficients, we found the range of principal components that covers the regular demand. The ranges are determined as 1~60 and 1~80 for Sejong and Seoul respectively.

  • The flash memory has many advantages such as low power consumption, strong shock resistance, fast I/O and non-volatility. And it is increasingly used in the mobile storage device. Many researchers are studying the YAFFS, NAND flash file system, which is widely used in the embedded device. However, the existing YAFFS has two problems. First, it takes long time to mount the YAFFS file system because it scans whole spare areas in all pages. Second, the cleaning policy of the YAFFS does not consider the wear-leveling so that it cannot guarantee the duration of data completely. In order to solve these problems, this paper proposes a new content-based YAFFS that consists of a mounting time reduction technique and a content-cleaning policy by using content-based block management. The proposed method only scans partial spare areas of some special pages and provides the block swapping which enables the wear-leveling of data blocks. We performed experiments to compare the performance of the proposed method with those of the JFFS2 system and YAFFS system. Experimental results show that the proposed method reduces the average mounting time by 82.2% comparing with JFFS2 and 42.9% comparing with YAFFS. Besides, it increases the life time of the flash memory by 35% comparing with the existing YAFFS whereas no overheat is added.

  • A fruit rot of sweet persimmon(Diospyros kaki cv. 'Fuyu') that infected with blue mold was found during the storage and transport in Jinju Gyeongnam Province, Korea. Fruit surfaces that infected with the fungus were formed water soaked lesion at first then gradually colonized with the fungus and formed mycelial mats. From the point of infection, fruits become sunken and mostly ruptured. The pathogenic fungus was isolated from infected fruits and cultured on potato dextrose agar. The colonies of the pathogenic fungi were white at frist then became greyish green on malt extract agar. Conidia were ellipsoidal and $2.6{\sim}3.8{\times}2.4{\sim}3.8{\mu}m$ in size. Phialides were ampulliform, verticilate of 3-7, $8.0{\sim}9.2{\times}2.0{\sim}3.0{\mu}m$ in size. Metulae were verticils of 2-4, smooth, $9.0{\sim}12.6{\times}3.0{\sim}4.6{\mu}m$ in size. Ramuli were groups 1-3, smooth, $11.0{\sim}17.6{\times}2.3{\sim}3.0{\mu}m$ in size. Rami were groups 1-2, $7.5{\sim}32.6{\times}2.6{\sim}4.2{\mu}m$ in size. Stipes were septate, smooth, thin walled, $56{\sim}302{\times}2.8{\sim}4.0{\mu}m$ in size. Penicilli were mostly quaterverticillate. Based on the cultural and mycological characteristics as well as pathogenicity test on host plants, the fungus was identified as Penicillium expansum. This is the first report on the blue mold of sweet persimmon(Diospyros kaki) caused by P. expansum in Korea.

  • 앙드레 꾸레쥬는 자신의 디자인에 건축적 조형미를 표현한 대표적인 디자이너이다. 그의 디자인들은 라인 뿐 아니라 색채, 소재, 액세서리에 이르기까지 건물을 짓듯이 설계, 구성되어 있다. 최근 복식미의 건축적 조형성이 강조되고 있는 것을 감안할 때, 60년대 이미 선구자적인 역할을 하면서 자신의 건축가적인 기호를 유감없이 발휘해온 꾸레쥬를 연구한다는 것은 21세기를 향한 패션의 발전 측면에서 조금이라도 의미가 있지 않을까 생각한다. 본 연구에서는 앙드레 꾸fp쥬가 가장 활발히 활동했던 1974년에서 1970년까지 그의 디자인들을 집중 연구하였는데, 그의 패션디자인에 건축양식의 특징들이 어떻게 나타났는지에 연구의 초점을 맞추었다. 본 연구의 대상으로 사용된 실제의 옷 샘플들은 뉴욕 메트로폴리탄 예술박물관내의 Costume Institute Storage 에 있는 의복과 액세서리들을 직접, 관찰 , 분석한것이고 그 박의 사진들은 패션과 건축에 관한 서적과 잡지, 박물관내의 Slide Library , 그리고 Costume Institute Library Collection에서 발췌 , 비교 연구한 것이다. 일찍이 엔지니어링과 건축을 공부했던 앙드레 꾸레쥬는 50년대의 패션 디자이너의 거장 발렌시아가 밑에서 10년 넘게 일하다가 독립하였는데 그의 디자인 세계는 줄곧 여성들이 입고 편히 활동 할 수 있는 기능성을 강조하면서 단순하고 편안한 의복 구성에 중점을 두었다. 그리고 그는 이러한 자신의 패션 철학과 의복제작 과정들은 현대건물이 갖는 단순성, 기능성의 특징과 일치한다고 믿었다. A. 라인(Line) 앙드레 꾸레쥬는 패션 디자인에서의 비레는 건축에서구조를 쌓아가는 것과 같은 것이라고 생각하고 옷에서의 기본 구성을 기하학적인 라인에 두었다. 그래서 그의 옷들은 A-라인, 사각형, 사다리꼴,,, 등의 분명한 실루엣을 이루고 있는데 이러한 기본라인을 뒷받침이라도 하듯 소매가 아주 짧거나 없는 것이 특징이다. 황금분할이 아닌 1 : 1 구성은 그가 독특하게 사용한 비례방법의 하나인데 그것은 자켓과 스커트의 길이비례, 요크와 몸판간의 면적비례 등에서 잘 나타나고 있다. 그리고 그는 , 의복구성의 비례를 강조하기 위해 사용한 강한 색상의 대비를 현대건물의 인테리어에 빛을 사용하는 것과 같은 이치라고 설명한다. B.색상(Color) 흰색은 그러한 그의 비례강조 의복에 가장 적절한 색으로 사용되었다. 그는 빨강, 오렌지, 녹색, 분홍등 강렬한 원색을 사용하였는데도 불구하고 흰색은 그의 건축양식 발상의 Ideo를 완성시키는 완전한 색이었다. 뜨거운 날씨에 흰색이 가장 기능적인 색인 것처럼 강한 원색 대비를 통해 비례강조를 하면서 동시에 그것을 뒷받침하는 가장 합리적이고 기능적인 색은 흰색이라고 믿었다. C. 소재 (Material) 앙드레 꾸레쥬는 건물을 짓듯이 사람위에 옷을 건축한다고 믿었기 때문에 자연히 둔탁하고 딱딱한 소재가 많이 사용되었다. 비닐, 금속류, 시퀸스처럼 광택나고 투명한 재료 선호는 그 당시 현대 건축에서 선풍적으로 많이 사용되었던 유리, 금속류, 크리스탈 등 비치고 광택나는 건축재료와 일맥상통하는 것이다. 그러한 선국적인 내료 사용결과로 보여진 괴상하고 선정적인 그러면서도 아주 단순한 패션은 미래 지향적인 건축양식 구조의 " Simple", "Plain" 느낌과 정확하게 같은 것이다. 이상과 같이 앙드레 꾸레쥬는 옷을 디자인 했다기 보다는 건축했다. 주목할만한 점은 60년대 말 당시 발표되었던 그의 건축 구조적인 디자인의 특징들이 21세기를 앞둔 90년대에 다시 크게 유행하고있다는 점이다. 꾸레쥬 역시, 최근 자신의 디자인을 통해 건축적 조형미와 미래지향적 이미지를 더욱 강조하고 있는 것을 볼 수있다. 단순하면서 우주공간을 선회하는 듯한 입체적인 라인, 흰색을 비롯한 자연에 가까운 색을 중심으로 하되, 밝은 색조의 하이라이트, 플라스틱, 금속류와 같이 딱딱하고 광택나며 비치는 재료 사용,, 등등이 바로 그것이다. 그리고 이러한 그에 미래 지향적이고 조형적인 디자인들은 앞으로 어떻게 더 모험적인 모습으로 선보일지 우리 모두가 주목할만한 일인 것이다.

  • The objective of this study was to determine the effects of E. coli isolated from porcine semen on sperm viability, motility, and semen pH. Semen samples were prepared using commercial extender, $Seminark^{Pro}$ (Noahbio Tech, Korea) that did not contain antibiotics. And 4 different levels of E. coli were artificially innoculated to semen with following concentrations; 4,000 of sperms with 1 of E. coli (T1), 400 with 1 (T2), 40 with 1 (T3), and 4 with 1 (T4). Semen samples were preserved at $17^{\circ}C$ for 5 days in semen storage box until analyzed by flowcytometer. Aliquots were subjected to measure the sperm viability (Live/$Dead^{(R)}$ stain), motility (mitochondrial function), and semen acidity (pH) from day 0 (day of semen collection) to day 5. Sperm motility and viability were significantly decreased (p<0.05) on day 0 (4 hrs after preservation at $17^{\circ}C$) in T3 and T4 compared to control groups and were significantly decreased (p<0.05) in all groups from day 3. Sample pH was acidic in T3 (6.90~6.86) and T4 (6.86~6.65) from day 3 to day 5 (p<0.05). On the other hand, sample pH was maintained 7.0~7.1 in control, T1, and T2 during the experimental period. Sperm motility and viability were significantly decreased from day 0 to day 5 compared to control in samples contaminated with E. coli above a value of 40:1 ($20{\times}10^6$ sperm cells/ml : $5{\times}10^5$ cfu/ml). Even on day 1 in T4 and on day 3 in T3, semen pH was acidic probably due to the acidification of dead spermatozoa. These results suggest that E. coli contamination has a concentration-dependent detrimental effect on extended porcine semen quality.

  • Ammonia is very toxic, and causes neuronal damage via excitotoxicity, oxidative stress, and inflammation. Because the liver is the primary organ for ammonia metabolism, compromised liver function can result from inborn errors of metabolism. Measurement of blood ammonia has some limitations. Recently, several laboratories examined possible concurrent increases in plasma ammonia. However, the collection, handling, storage, and analysis of blood samples are all potential sources of error. For evaluation of rapidity and reliability of measurement of blood ammonia, the DRI-CHEM 100 (Fuji Film Co., Japan) and COBAS 8000 (Roche Diagnostic Ltd., Switzerland) analyzer were used for analysis of ammonia level values. The results of this study detected a high correlation between analyzer. Therefore, one-step measurement was suitable for ammonia analysis. After sampling of the ammonia in the time slot for measurement an increase to 46.5, 57.4, and 79.0 (${\mu}g/dL$) was observed at 30, 90, and 180 minutes. In addition, specific capacity of the ammonia, 7, 10, and 13 (${\mu}L$), was measured as 39, 46, and 43 (${\mu}g/dL$), respectively, and the FDC-100 analyzer was more effective in $10{\mu}L$ (p<0.001). In conclusion, the evaluated analysis may offer useful information for clinical application.
