Aptamers are functional nucleic acids that can specially bind to proteins, peptides, amino acids. nucleotides, drugs, vitamins and other organic and inorganic compounds. The aptamers are identified from random DNA or RNA libraries by a SELEX (systematic evolution of ligands by exponential amplification) process. As aptamers have the advantage, and potential ability to be released from the limitations of antibodies, they are attractive to a wide range of therapeutic and diagnostic applications. Aptamers, with a high-affinity and specificity, could fulfil molecular the recognition needs of various fields in biotechnology. In this work, we reviewed some aptamer Selection techniques, properties, medical applications of their molecules and their biotechnological applications, such as ELONA (enzyme linked oligonucleotide assay), flow cytometry, biosensors, electrophoresis, chromatography and microarrays.

Primary prevention of low back injury in industry has focused on assessing the person's ability to perform physical labor. If the job to be performed is known to require lifting and moving of materials which could stress the low back, then special consideration is given to the health and functional capability of the person, s back. The major pursuit in lifting task of research is to provide objective criteria based upon all of the relevant mechanical parameters which describe both man art task so as to minimize the probabilities of injury within the economic constraints of each organization. The purpose of this study is to predict the back compression of persons asked to lift objects while assuming different position by computer simulation. The primary result of this study is that the incidence of low back injury is correlated with higher lifting strenth requirements as determined by assessment of both the location and magnitude of the load lifted. It is, therefore, recommended that load lifting be considered potentially hazardous, and the action limit and the maximum permissiable limit be used to guide corrective action.

Lead-acid battery is being most widely used with secondary battery because of its low price, and long life cycles. But According to using for a long time, its voltage, capacity, and recovery ability is decreased gradually. Therefore there are many papers about improving the property of a lead-acid battery. One of them is to slow down sulfation due to formation of inner PbSO sub(4) by adding inhibitor to electrolyte, however it was not well known what is inhibitor's composition and its role acting on both cathodic and anodic electrode because of its know-how of every country and companies. The purpose of this paper is to study about improvement of property of lead-acid battery by adding one of the inhibitor to H sub(2) SO sub(4) electrolyte.

In this paper, the structural analysis, which used Fuzzy Structural Modeling, was conducted about the 24 core cometencies of CEO of SME. It classified them into five groups. Also, regression analysis was conducted to evaluate the relationship beween the job capability and core competencies of the CEO. The characteristic of this paper is to know the relationship beween the structure and classification of the layers for the core competency of CEO, and is to know that each competency group has an influence on the job capability of CEO.

The Wnt signaling pathway plays pivotal roles in embryonic development and oncogenesis through various signaling molecules inculding Frizzled receptor, recently characterized LRP5/6 and Dickkopf protein. Although Wnt signaling has been characterized in both developmental and oncogenic processes, little is known about its function in the normal adult. The ability of LRP5 to bind apolipoprotein E(apoE) and the abundant expression of LRP5 transcripts in hepatocytes, raise the possibility that LRP5 plays a role in the hepatic clearance of ApoE-containing chylomicron remonants, a major plasma lipoprotein carrying diet-derived cholesterol.

Presently, Analytic Network Process which evaluates man's intention and offers decision-making support is capturing the spotlight. It originates in the ability of Analytic Network Process to treat various decision-making support system. However, no detailed reference is available when dealing with the group case. This paper examines the technique, which can also cope with the group decision-making support system, and describes the validity of the technique. A characteristic feature of the proposed technique is that it can detect a group's intention in a given section, and it decomposes the sectional supermatrix into a small supermatrix and a large one. A general supermatrix treats the convergence value by taking the limiting process method of the power of an evaluation value. On the other hand, when a supermatrix has nonnegative value, it can easily be solved by the eigenvector method. The decomposition of the supermatrix has been considered in this work.

IT technology based projects was conducted to implement education on producing creative ideas through on-line education and grasp thinking disposition of students in terms of creativity education efficiency. The differences in idea creation among students according to thinking dispositions were analyzed through qualitative evaluation and quantitative evaluation of project and its result was drawn. The purpose of this study was to help cultivate a man of ability who will make a great contribution to knowledge information society by proposing education model based on new method of teaching and learning.

There is a concern that chemicals in our environment are affecting human health by disrupting a normal endocrine function. Much of the concern has focused on chemicals that can interact directly with steroid hormone receptors. The ability of certain man-made chemicals to mimic the effects of natural steroid hormones and their potential to disrupt the delicate balance of the endocrine system in animals are of increasing concern.

HDL(Hardware Description Language) is the most important modem tools used to describe hardware, and becomes important as we move to higher levels of abstraction. The HDL has been made brisk use of in analog design, MEMS device[1-2], process related field as well as digital design. The most important characteristics of HDL is Abstraction which is the strongest tool that extend greatly designer's design ability. In this paper by the Modelling Continuum with hierarchical structure of abstraction, we apply UML(Unified Modeling Language) to SoC Design with HDL UML makes an easy and visual description of the various levels of abstraction, and gives designers good flexible modeling capabilty for SoC Design.
