Elbow traumas represent a relatively common condition in clinical practice. However, there is a lack of evidence regarding the most accurate tests for screening these potentially serious conditions and excluding elbow fractures. The purpose of this investigation was to analyze the literature concerning the diagnostic accuracy of clinical tests for the detection or exclusion of suspected elbow fractures. A systematic review was performed using the Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines. Literature databases including PubMed, Cumulative Index to Nursing and Allied Health Literature, Diagnostic Test Accuracy, Cochrane Library, the Web of Science, and ScienceDirect were searched for diagnostic accuracy studies of subjects with suspected traumatic elbow fracture investigating clinical tests compared to imaging reference tests. The risk of bias in each study was assessed independently by two reviewers using the Quality Assessment of Diagnostic Accuracy Studies 2 checklist. Twelve studies (4,485 patients) were included. Three different types of index tests were extracted. In adults, these tests were very sensitive, with values up to 98.6% (95% confidence interval [CI], 95.0%-99.8%). The specificity was very variable, ranging from 24.0% (95% CI, 19.0%-30.0%) to 69.4% (95% CI, 57.3%-79.5%). The applicability of these tests was very high, while overall studies showed a medium risk of bias. Elbow full range of motion test, elbow extension test, and elbow extension and point tenderness test appear to be useful in the presence of a negative test to exclude fracture in a majority of cases. The specificity of all tests, however, does not allow us to draw useful conclusions because there was a great variability of results obtained.

We have proposed BIST method and circuit for embedded 16M SDRAM with logic. It can test the AC parameter of embedded 16M SDRAM using the BIST circuit capable of detecting the address of a fail cell installed in an Merged Memory with Logic(MML). It generates the information of repair for redundancy circuit. The function and AC parameter of the embedded memory can also be tested using the proposed BIST method. It is possible to test the embedded SDRAM without external test pin. The total gate of the BIST circuit is approximately 4,500 in the case of synthesizing by 0.25μm cell library and is verified by Verilog simulation. The test time of each one AC parameter is about 200ms using 2Y-March 14n algorithm.

Shortest path problem belongs to the combinatorial optimization problem and plays an important role in the field of computer aided design. It can either be directly applied as in the case of routing or serves as a important subroutine in more complex problems. In this paper, a systolic array for the SSSP(single-source shortest path problem) was derived. The array was modeled and simulated in RTL level using VHDL, then synthesized to a schematic and finally implemented to a layout using the cell library based on 0.35 $\mu\textrm{m}$ CMOS 1-poly 4-metal CMOS technology.

In this paper, we describe implementation of 32-Bit RISC Core for portable communication/information equipment, such as cellular telephones and personal digital assistants, notebook, etc. The RISC core implements the ARM$\^$R/V4 instruction set on the basis of low power techniques in architecture level and logic level. It operates with 5-stage pipeline, and has harvard architecture to increase execution speed. The processor is modeled and simulated in RTL level using VHDL. Behavioral Cache and MMU are added to the VHDL model for instruction level verification of the processor. The core is implemented using Mentor P'||'&'||'R tools with IDEC C-631 Cell library of 0.6$\mu\textrm{m}$ CMOS 1-poly 3-metal CMOS technology.

A thoredoxin (CTRX) gene was cloned and characterized from a full length cDNA library prepared from taproot of three-year old Codonopsis lanceolata. A CTRX was 666 nucleotides long and has an open reading frame of 372 bp with 124 amino acid residues (pI = 4.92). The deduced amino acid sequence of the CTRX matched to the previously reported plant thioredoxin h genes. The deduced amino acid sequence of CTRX exhibited the similarity of 33-67% among previously registered thioredoxin genes. The expression of CTRX in leaves of Codonopsis lanceolata was increased by wounding and 1 mM $H_2O_2$, but decreased by 0.1 mM cadmium.

We have constructed the Rice Genome Information Service System (RGISS), which is an information service system of the Oryza sativa L. ssp. japonica (rice) genome, using the released version of rice Build 3.0 pseudomolecules based on the Ensembl architecture. The nonredundant library, composed of 3,360 clones of BACs, PACs, and fosmids, was used to construct supercontigs. RGISS contains 50,717 annotated genes from GenBank, 56,161 predicted genes from FgeneSH, and information on 9,587 markers, which includes STS, SSR, and EST-based RFLP. The 20,180 ESTs sequenced by the Korea National Institute of Agricultural Biotechnology (NIAB) were aligned and mapped into 168,792 exons. By gene ontology analysis, the classified protein numbers in the rice genome were 6158, 4531, and 12,364 proteins, which were mapped to molecular function, cellular component, and biological process, respectively.

This study develops and operating software for a model plant. The model plant consists of an AS/RS system, two machining centers, an assembly line, and supplementary material handling equipments. Devices of each component are connected with the IBS RT24 DIO 16/16-T I/O module. Each I/O module communicates digital signals with the INTERBUS controller board via SUB-D 9 Connector cable. This study is a previous stage for developing an educational CIM software. Petri Nets is used for modelling the storage/retrieval of the AS/RS system, the flow of workpieces and the assembly line for parts. The operating software is coded with Microsoft Visual $C^{++}$ 5.0 and Interbus Library which is a software driver for the controller board. The operating software can be run on a MS Windows 95. Microsoft Access is used for the implementation of databases for BOM, AS/RS, and parts.

Developing highly cost-efficient and reliable embedded systems demands hardware/software co-design and co-simulation due to fast TTM and verification issues. So, it is essential that Platform-Based SoC design methodology be used for enhanced reusability. This paper addresses a reusable SoC platform based on OpenCores soft processor with reconfigurable architectures for hardware/software codesign methodology. The platform includes a OpenRISC microprocessor, some basic peripherals and WISHBONE bus and it uses the set of development environment including compiler, assembler, and debugger. The platform is very flexible due to easy configuration through a system configuration file and is reliable because all designed SoC and IPs are verified in the various test environments. Also the platform is prototyped using the Xilinx Spartan3 FPGA development board and is implemented to a single chip using the Magnachip cell library based on $0.18{\mu}m$ 1-poly 6-metal technology.

필자는 지금부터 5개월 전인 2011년 2월 1일자로 15년간 근무한 대학도서관을 떠나 대학 기획팀으로 자리를 옮겼다. 15년이란 시간이 결코 짧지 않기에 막상 도서관을 떠나 대학행정부서로 이동한다는 사실을 받아들이는데 힘이 들었다. 평소 '사람만큼 환경에 잘 적응하는 동물도 없다'라는 말에 상당히 공감하는 편이지만, 학부기간을 포함하면 거의 20년을 넘게 함께 한 도서관 현장을 떠난다는 아쉬움과 섭섭함, 그리고 새로운 환경에 잘 적응할 수 있을까?'라는 두려움이 복잡하게 교차했었다. 특히, 사서e마을의 운영, 관리는 큰 걱정이자 숙제이다. 왜냐하면 대학행정부서에서 근무하다보면 아무래도 도서관계 동향이나 정보에 대해 무뎌질 수밖에 없고 본의 아니게 사이트 운영에 소홀해질 개연성이 높다고 하겠다. 다행스러운 점은 2010 년 5~6월경 사서e 마을의 운영시스템을 제로보드 4.0에서 제로보드 XE로 개편한 점인데, 이는 제로보드 XE가 사이트 관리에 있어 편의성, 시스템적 안정성이 이전 버전에 비해 한층 낫기 때문이다. 이미 언급한 바와 같이 대학 기획팀에서 근무한 지 겨우 5개월 지났다. 15년의 도서관 경력에 비할 바는 아니지만 최근 대학도서관 사서직원의 대학행정부서 이동이 이전에 비해 훨씬 많아진 점에 착안하여 이의 동향과 원인, 득실에 대하여 살펴보고자 한다.

The firtst-order conditional moment closure (CMC) model is applied to CH4/air swirl diffusion flame in a gas turbine model combustor. The flow and mixing fields are calculated by fast chemistry assumption with SLFM library and a beta function pdf for mixture fraction. RNG k-e model is used to consider the swirl flame in a confined wall. Reacting scalar fields are calculated by elliptic CMC formulation with chemical kinetic mechanism, GRI Mech 3.0. Validation is done against measurement data for mean flow and scalar fields in the model combustor [1]. Results show reasonable agreement with the mean mixture fraction and its variance, while temperature is overpredicted as the level of local extinction increases. The second-order CMC model is needed to consider local extinction with considerable conditional fluctuations near the nozzle.
