The SECS(SEMI Equipment Communications Standard) is a standard protocol for communication between equipments and a host in semiconductor processes. This paper proposes the implementation of the HSMS(High-speed SECS Message Services) as an interface for transmission of the SECS messages and SECS-II containing message contents defined as an SEMI standard. The HSMS driver is implemented as a type of the daemon program and several DLL files. The SECS-II composes of the SML(SECS Message Language) file defining the SECS messages, the SML translator being able to interpret and transform the SML, and the data index table being able to refer to SECS messages. We also define the shared parameter to exchange the HSMS header and SECS message between the HSMS and the SECS-II. Eventually, to show the effectiveness of the proposed drivers, we test the SECS communications between equipments and a host using the implemented communication programs.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to spring framework 2.5. Non EJB and the EJB architecture to resolve the problem with benefits to support the new architecture is a lightweight container architecture. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business spring framework is well-known architecture. Therefore, this research has the Non EJB and the EJB to solve the advantages and disadvantages developed to support the latest spring framework 2.5 lightweight container architecture based on the design and implementation of a pilot system with the objective through the specification of the software previously to provide guidance to development productivity.

This study focuses on the case of FIRA(Korea Fisheries Resources Agency) and analysis the introduction effect of BSC(Balanced Score card) implementation. So it will set forth the improvement method and the implications for Quasi-governmental organizations which are trying to introduce or are operating the BSC system. This study suggests how to improve the problems of BSC as below : (1) Building of reasonable and balanced evaluation index system (2) Acquiring of comparability and equality through adjustments of group evaluated (3) Enhancing of competence and professionalism of evaluating group (4) Alleviating of difference gap of performance incentives and promoting of non-money incentives (5) Enhancing of positive acceptance and recognition for BSC.

This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to Seam Framework. Heavyweight and lightweight architecture to resolve the problem with benefits to support the new architecture is a large size distributed object standardization architecture. This architecture, such as the Seam Framework, to provide all of the architecture is possible. The distributed object standardization architecture is most often used in business Seam Framework is well-known architecture. Therefore, this study is based on the Seam Framework large distributed object architecture, design and implementation of standardization software development productivity and the objective is to provide guidance.

Objective: To evaluate the implementation of screening colonoscopy amongst first-degree relatives (FDRs) of patients with colorectal cancer (CRC) in Turkey. Materials and Methods: A total of 400 first-degree relatives (mean(SD)age: 42.5(12.7) years, 55.5% were male) of 136 CRC patients were included in this cross-sectional questionnaire based survey. Data on demographic characteristics, relationship to patient and family history for malignancy other than the index case were evaluated in the FDRs of patients as were the data on knowledge about and characteristics related to the implementation of screening colonoscopy using a standardized questionnaire form. Results: The mean(SD) age at diagnosis of CRC in the index patients was 60.0(14.0) years, while mean(SD) age of first degree relatives was 42.5(12.7) years. Overall 36.3% of relatives were determined to have knowledge about colonoscopy. Physicians (66.9%) were the major source of information. Screening colonoscopy was recommended to 19.5% (n=78) of patient relatives, while 48.7% (n=38) of individuals participated in colonoscopy procedures, mostly (57.9%) one year after the index diagnosis. Screening colonoscopy revealed normal findings in 25 of 38 (65.8%) cases, while precancerous lesions were detected in 26.3% of screened individuals. In 19.0% of FDRs of patients, there was a detected risk for Lynch syndrome related cancer. Conclusions: In conclusion, our findings revealed that less than 20% of FDRs of patients had received a screening colonoscopy recommendation; only 48.7% participated in the procedure with detection of precancerous lesions in 26.3%. Rise of awareness about screening colonoscopy amongst patients with CRC and first degree relatives of patients and motivation of physicians for targeted screening would improve the participation rate in screening colonoscopy by FDRs of patients with CRC in Turkey.

This paper describes an implementation of a graph-based simultaneous localization and mapping(SLAM) method called the General Graph Optimization. The General Graph Optimization formulates the SLAM problem using nodes and edges. The nodes represent the location and attitude of a robot in time sequence, and the edge between the nodes depict the constraint between the nodes. The constraints are imposed by sensor measurements. The General Graph Optimization solves the problem by optimizing the performance index determined by the constraints. The implementation is verified using the measurement data sets which are open for test of various SLAM methods.

In this paper, we design and implement a distributed, moving objects management system for processing locations and sensor data from smart black boxes. The proposed system is designed and implemented based on Apache Kafka, Apache Spark & Spark Streaming, Hbase, HDFS. Apache Kafka is used to collect the data from smart black boxes and queries from users. Received location data from smart black boxes and queries from users becomes input of Apache Spark Streaming. Apache Spark Streaming preprocesses the input data for indexing. Recent location data and indexes are stored in-memory managed by Apache Spark. Old data and indexes are flushed into HBase later. We perform experiments to show the throughput of the index manager. Finally, we describe the implementation detail in Scala function level.

This paper proposes an image-dependent color image enhancement method that uses adaptive luminance enhancement and color emphasis. It effectively enhances details of low-light regions while maintaining well-balanced luminance and color information. To compare the structure similarity and naturalness, we used the tone mapped image quality index (TMQI). The proposed method maintained better structure similarity in the enhanced image than did the space-variant luminance map (SVLM) method or the adaptive and integrated neighborhood dependent approach for nonlinear enhancement (AINDANE). The proposed method required the smallest computation time among the three algorithms. The proposed method can be easily implemented using the field-programmable gate array (FPGA), with low hardware resources and with better performance in terms of similarity.

This paper forces on the analysis of the overall outcome regarding Performance Based Logistics(PBL) application for Air Weapon System. We used data from domestically developed aircraft such as KT/A-1 and T-50 as well as data from foreign F-15K aircraft and F100 Engine to analyze the current ROKAF PBL application results. Furthermore, this paper thus suggests various techniques to maximize the outcome of user-based PBL performance such as clarifying the responsibility between customer and the company, developing standardized PBL performance index under TLCSM, PBL related maintenance capacity development, wartime PBL implementation process of domestic/foreign companies and many other schemes based on the analyzed data.

In this paper, we propose a recovery method for high dimensional index structures. It recovers efficiently transactions including reinsert operations that needs undo or rollback due to system failures or transaction failures. It is based on WAL(Write Ahead Logging) protocol. We apply the method to the FCIR-Tree and implement it based on MiDAS-III which is the storage system of a multimedia DBMS, called BADA-III. We also show through performance evaluation that the recovery method with our algorithm recovers reinsert operations efficiently over that without our algorithm.
