망 환경에서 PC 사용자들의 멀티미디어 데이타 검색이 점차 증가하고 있다. SQL CLI(Call Level Interface)는 클라이언트-서버 환경에 적합한 데이터베이스 응용 프로그래밍 인터페이스(API)로서, 현재의 표준안에서는 멀티미디어 데이터와 같은 대용량 데이터의 효율적 검색을 위한 기능을 다양하게 제공해 주지 못하고 있다. 본 논문에서는 멀티미디어 데이터를 구성하는 LOB(Large OBject)의 빠른 검색을 위하여 SQL CLI 상에서 LOㅠ의 캐쉬를 제안하고, 이를 위한 SQL CLI 함수의 확장을 제안한다. 그리고 제안한 함수 중 일부를 SQL CLI를 지원하는 실제 DBMS 상에서 구현하여 LOB 캐쉬의 성능을 평가한다.

In this paper, we design and implement a query processor of real-time main memory database systems, which reflect the characteristics of main memory database systems and satisfy timing constraints. The proposed query processor manages real-time data that has timing constraint by exploiting meta database. It supports CLI in order to make application programs. It also supports extended CLI and stored CLI. The former can be expressed the Information on real-time transaction. The latter is designed to support frequently processed transaction. The proposed query processor is implemented as query processor of real-time database management systems. We Present performance evaluation results that illustrate ratio of transaction, which satisfy deadline are increased by the query processing ability of system and the efficient management of real-time data.

The SQL CLl (Call Level Interface) is a database application programming interface (API) that fits the client-server environment, and its de facto standards such as ODBC and JDBC are widely employed in various applications. The current SQL CLl standards, however, do not specify enough features for efficient retrieval of large objects (LOBs) that constitute the multimedia data. In this paper, we propose the LOB caching through the SQL CLl and describe the extension of the SQL eLl to achieve such a goal. We implement our proposal by extending the SQL CLl library for BADA - II DBMS developed at ETRI, and evaluate the performance of LOB retrieval through the cache compared to that of LOB retrieval conducted solely with the functions specified in the current SQL CLl standards.

The CLI(Consumer Life Information) is a new study to unite and create new values recognizing the importance of knowledge and information in information-oriented society based on domestic science and digital technology. The objective of this research is to define academic identity of consuming science and CLI, to analyze the theory, styles, manners, psychology and the concept of consumption, which is the base of consuming life, and to present the direction of CLI with tasks and three major axises of CLI. Nowadays, international order demands new paradigms from human beings. Especially, vision and creation of the values are settled as methodological ways considering the economic power. The CLI should be on the same horizon adjusting social change of pointing values and quality in consuming patterns of diversity and variety. Therefore, I would suggest the ways for the CLI to head for as follows. First, it is to perceive the 3 major Axises & Task of CLI. Second, it is to develope service (experiencing goods) and goods that can lead consuming lives. Third, it is to study merchandising strategy, to create new signs and symbols of goods, and to collaborate of R & D(reseach and developement) and Business. Fourth, it is to head for globalization. Consequantly, this study will be helpful to establish the theory of relationship between producer and consumer in fashion business included research and developments of qualitative goods.

Correlation of KOSPI from stock market and Apartment Prices in Seoul HPPCI from real estate market has been found from this research. Furthermore, from the comparison of those indicators' flows, certain precedence was found as well. The purpose of this research is to analyze correlation and precedence among KOSPI, Apartment price in Seoul, HPPCI and CLI. As for predicting KOSPI of stock market and real estate market, it is necessary to find out preceding indices and analyzing their progresses first. For 27 years from the January 1987 to December 2013, KOSPI has been grown by 687%, while CLI showed 443%, Apartment of Seoul showed 391%, HPPCI showed 263% of growth rate in order. As the result of correlation analysis among Apartment of Seoul, CLI, KOSPI and HPPCI, KOSPI and HPPCI showed high correlation coefficient of 0.877, and Apartment of Seoul and CLI showed that of 0.956 which is even higher. Result from the analysis, CLI shows high correlation with stock and real estate market, it is a good option to watch how CLI flows to predict stock and real estate market.

한국형 차세대 원자로(KNGR)는 안전주입계통에 Advanced Design features를 채택하고 있는데, 그 중의 하나가 안전주입의 주입구를 Downcomer Annulus의 상부에 위치시킨 Direct Vessel Injection(DVI)으로서 영광 및 울진 3&4호기의 Cold Leg Injection(CLI)과는 다른 설계 개념이다. 본 논문에서는 DVI가 채택된 KNGR에 대하여 기존의 C-E형 발전소 해석에 적용한 C-E Evaluation Model(EM)을 사용하여 대형파단 냉각재상실사고를 해석해 보고자 하였다. 먼저 DVI의 Modeling은 KNOGR의 참조 발전소라 할 수 있는 System80+에서 Modeling한 것과 같이 CLI 해석에 사용한 Nodalization Scheme 중 Cold Leg Node에 연결된 SIT 만을 Downcomer Annulus Node에 연결하는 방법을 사용하여 DVI 해석을 수행하였다. 아울러 기존의 안전주입 형태인 CLI에 대한 해석을 KNGR에 대해 병행하여 수행함으로써 DVI와 CLI의 ECCS performance를 비교하고 CLI 대비 DVI의 특성을 알아보았다. 또한 DVI의 해석에 있어서 SIT와 Cold Leg이 함께 연결되는 Downcomer Annulus Node를 상하 2개로 분리하여 SIT와 Cold Leg 각각에 연결시킴으로써 DVI 주입구의 위치에 대한 보다 정확한 Modeling을 시도하였다. 그 결과 DVI 주입구의 높이를 고려한 경우가 DVI의 일반적 물리 현상에 근접하게 계산되는 것으로 판단되나 현재로서는 특별한 검증 수단이 없으므로 향후 Licensing 해석 수행에 앞서 방법론을 포함한 이에 대한 보다 심도 있는 검토가 필요할 것으로 판단된다.

Narrowing of arteries supplying blood to the limbs provokes critical hindlimb ischemia (CLI). Although CLI results in irreversible sequelae, such as amputation, few therapeutic options induce the formation of new functional blood vessels. Based on the proangiogenic potentials of stem cells, in this study, it was examined whether a combination of dental pulp stem cells (DPSCs) and human umbilical vein endothelial cells (HUVECs) could result in enhanced therapeutic effects of stem cells for CLI compared with those of DPSCs or HUVECs alone. The DPSCs+ HUVECs combination therapy resulted in significantly higher blood flow and lower ischemia damage than DPSCs or HUVECs alone. The improved therapeutic effects in the DPSCs+ HUVECs group were accompanied by a significantly higher number of microvessels in the ischemic tissue than in the other groups. In vitro proliferation and tube formation assay showed that VEGF in the conditioned media of DPSCs induced proliferation and vessel-like tube formation of HUVECs. Altogether, our results demonstrated that the combination of DPSCs and HUVECs had significantly better therapeutic effects on CLI via VEGF-mediated crosstalk. This combinational strategy could be used to develop novel clinical protocols for CLI proangiogenic regenerative treatments.

Variations of carotenoid and chlorophyll during the course of after-ripening in hotpepper fruits were studied: 1. Carotenoid pigments were fractionized into six fragments by means of column chromatography and each of six were applied to the TLC. By these procedures 30 kinds of carotenoids were identified among 54 kinds of different separations. 2. Total carotenoids increased very rapidly in cli. stage. And when compared group by group, Diol showed highest in amounts as well as in increasing index. 3. Decrease of phytoene in post-cli. stage and notable increase of capsanthin, capsorubin and violaxanthin amounts in carotenoid, as major pigments, were remarkable one. 4. Total amounts of chlorophyll a and b showed decreasing tendency during after-ripening and, finally, disappeard at the post-cli. stage.

To predict TBM performance in design stage is indispensable for its successful application. The NTNU model, one of the representative TBM performance prediction models uses two distinct parameters such as DRI and CLI obtained from three different tests on bored rock cores. Based on DRI and CLI, it is possible to predict TBM advance rate and cutter life in the NTNU model. In this study, NTNU testing methods and their related testing equipments were introduced to measure DRl and CLI for the NTNU model. Then, in order to derive their relationships, the two key parameters measured for 39 domestic rocks were compared with physico-mechanical properties of rock such as uniaxial compressive strength and quartz content. Lastly, the experimental results were also compared with NTNU database to verify their reliability.

Background: Self-reported low back pain (LBP) has been evaluated in relation to material handling lifting tasks, but little research has focused on relating quantifiable stressors to LBP at the individual level. The National Institute for Occupational Safety and Health (NIOSH) Composite Lifting Index (CLI) has been used to quantify stressors for lifting tasks. A chemical exposure can be readily used as an exposure metric or stressor for chemical risk assessment (RA). Defining and quantifying lifting nonchemical stressors and related adverse responses is more difficult. Stressor-response models appropriate for CLI and LBP associations do not easily fit in common chemical RA modeling techniques (e.g., Benchmark Dose methods), so different approaches were tried. Methods: This work used prospective data from 138 manufacturing workers to consider the linkage of the occupational stressor of material lifting to LBP. The final model used a Bayesian random threshold approach to estimate the probability of an increase in LBP as a threshold step function. Results: Using maximal and mean CLI values, a significant increase in the probability of LBP for values above 1.5 was found. Conclusion: A risk of LBP associated with CLI values > 1.5 existed in this worker population. The relevance for other populations requires further study.
