In this paper, we propose a numerical method to model temperature dependent threshold voltage shift observed in metal oxide thin-film transistors (TFTs). The proposed model is then implemented in AIM-SPICE circuit simulation tool. The proposed method consists of modeling the well-known stretched-exponential time dependent threshold voltage shift and their temperature dependent coefficients. The outputs from AIM-SPICE tool and the stretched-exponential model at different temperatures in the literature are compared and they show a good agreement. Since metal oxide TFTs are the promising candidate for flat panel displays, the proposed method will be a good stepping stone to help enhance reliability of fast-evolving display circuits.

EcoRl endonuclease is inactivated by diisopropylfluorophosphate (DFP), a serine residue modification reagent. The rate of inactivation is reduced by the substrate DNA and Mg^(++), The DNA cleavage activity of EcoRI endonuclease in inactivated by DFP, while the binding capacity of enzyme is not inactivated. Several lines of experimental evidence indicate that serine residue plays a very important catalytic role is EcoRI endonuclease. To generate peptide maps of the active serine residue region, the enzyme was labeled with (³H)DFP and digested with trypsin. The amino acid composition of the labeled peptide corresponds to a tryptic fragment including residues 146-169 in the EcoRI endonuclease sequence.

High Level Architecture (HLA)는 완성된 시뮬레이터를 연동함으로써 재사용성을 높이고 분산된 이기종 시뮬레이터간의 연동성을 확보하고자 제정된 연동 표준으로, Runtime Infrastructure (RTI)로 구현되어 다양한 시뮬레이터간의 연동 시뮬레이션을 중개한다. 이러한 연동 시뮬레이션 관련 연구는 연동 대상이 되는 시스템이 점점 복잡해짐에 따라 시뮬레이터간의 연동을 넘어 연동된 페더레이션 간의 연동으로 발전하고 있다. 그러나 기존의 연구들은 객체 모델 통합에 대한 고민이 없었기 때문에 객체 모델이 동일한 표준 형식을 따르며 차이점이 존재하지 않아 쉽게 통합될 수 있다고 가정하고 진행되었다. 그러나 다양한 HLA 표준에 기초한 페더레이션들이 이미 구현되어 있기 때문에 객체 모델의 형식에 차이점이 있어 기계적인 객체 모델 통합이 불가능하고, 실제로는 같은 객체/속성에 대해 다르게 기술되어 있을 가능성이 많다. 또한 모든 객체를 통합하여 공개했을 때에는 보안성의 문제도 존재한다. 따라서 본 논문은 이러한 문제를 해결하는 페더레이션 연동을 위한 객체 모델 통합 프로세스를 제안한다. 제안하는 객체 모델 통합 프로세스는 서로 다른 표준을 따르는 객체 모델 간의 통합 방법을 제안하고, 객체간의 서로 다른 이름/특성 문제를 해결하며, 보안객체를 제외하는 기능을 담고 있다. 본 연구를 통하여 페더레이션 연동 기술이 실제적으로 적용될 때에 각 페더레이션의 연동성과 재사용성을 향상시킬 수 있을 것으로 기대한다. High Level Architecture(HLA) is a specification for interoperation among heterogeneous simulators which are executed in a distributed environment. HLA originally allows many federates to join in a federation using a single RTI(Run-Time Infrastructure). As the target systems become more complex, the need for the interoperation of federations, performed in a RTI-RTI interoperation environment, has been growing. It can be performed by the confederation interface with the agents, which subrogate the API calls and callbacks of each federation. The existing studies have assumed that the object models of each federation are based on same HLA standard and their object descriptions are equal. Because the existing federations are usually not under this assumption, this paper proposes the integration process of object models for the federation interoperation environment. To integrate the object models for the interoperation of federations, this process resolves the differences of HLA standards, provides conversion process between objects with different descriptions and excludes the security objects. We expect that this process enhances the reusability and effectiveness of interoperation of federations in various domains.

임상에서 흔히 접하는 슬관절통의 감별진단

The knee is a complex structure and far from being the simple hinge joint of popular belief. Knee pain would not be properly understood unless one is familiar with the anatomy and understands the role of the various structures. For patient consultation or for selecting a treatment option, it is crucial to find the central cause of symptoms and functional disabilities of the patient based on a detailed history, a focused examination and, when indicated, the selective use of appropriate imaging and laboratory studies. The history taking should be comprehensive and include the demographic characteristics, past medical history, comprehending the associated trauma, pain characteristics and quality of life. Basic physical examination should include inspection of walking pattern and the knee, evaluation of joint effusion, range of motion and the location of tenderness, and precise assessment of joint stability. Although many advanced diagnostic tools are available, plain radiographs are frequently utilized as a primary tool to evaluate conditions of the knee joint for practical and economic reasons. A weight-bearing anteroposterior radiographs should be taken for appropriate evaluation of the condition of the tibiofemoral joint, and weight-bearing radiographs in semi-flexed position is valuable to evaluate the joint space more precisely. To evaluate the patellofemoral joint, axial and lateral views should be included in the routine radiographs. In practice, physicians need to be cautious not to easily reach the conclusion that the symptoms of the knee joint can be attributed to only a few clinical findings in consulting the patients with knee pain.

The primary purpose of the present study is to provide the sources to improve the mathematical problem solving performance by analyzing the effects of the belief systems and the misconceptions of the middle school students in solving the problems. To attain the purpose of this study, the research is designed to find out the belief systems of the middle school students in solving the mathematical problems, to analyze the effects of the belief systems and the attitude on the process of the problem solving, and to identify the misconceptions which are observed in the problem solving. The sample of 295 students(boys 145, girls 150) was drawn out of 9th grade students from three middle schools selected in the Kangdong district of Seoul. Three kinds of tests were administered in the present study : the tests to investigate (1) the belief systems, (2) the mathematical problem solving performance, and (3) the attitude in solving mathematical problems. The frequencies of each of the test items on belief systems and attitude, and the scores on the problem solving performance test were collected for statistical analyses. The protocals written by all subjects on the paper sheets to investigate the misconceptions were analyzed. The statistical analysis has been tabulated on the scale of 100. On the analysis of written protocals, misconception patterns has been identified. The conclusions drawn from the results obtained in the present study are as follows; First, the belief systems in solving problems is splited almost equally, 52.96% students with the belief vs 47.05% students with lack of the belief in their efforts to tackle the problems. Almost half of them lose their belief in solving the problems as soon as they give. Therefore, it is suggested that they should be motivated with the mathematical problems derived from the daily life which drew their interests, and the individual difference should be taken into account in teaching mathematical problem solving. Second, the students who readily approach the problems are full of confidence. About 56% students of all subjects told that they enjoyed them and studied hard, while about 26% students answered that they studied hard because of the importance of the mathematics. In total, 81.5% students built their confidence by studying hard. Meanwhile, the students who are poor in mathematics are lack of belief. Among are the students accounting for 59.4% who didn`t remember how to solve the problems and 21.4% lost their interest in mathematics because of lack of belief. Consequently, the internal factor accounts for 80.8%. Thus, this suggests both of the cognitive and the affective objectives should be emphasized to help them build the belief on mathematical problem solving. Third, the effects of the belief systems in problem solving ability show that the students with high belief demonstrate higher ability despite the lack of the memory of the problem solving than the students who depend upon their memory. This suggests that we develop the mathematical problems which require the diverse problem solving strategies rather than depend upon the simple memory. Fourth, the analysis of the misconceptions shows that the students tend to depend upon the formula or technical computation rather than to approach the problems with efforts to fully understand them. This tendency was generally observed in the processes of the problem solving. In conclusion, the students should be taught to clearly understand the mathematical concepts and the problems requiring the diverse strategies should be developed to improve the mathematical abilities.
