Software documents consist of a number of objects and relationships between them, and structure of documents can be changed frequently. In the existing software version management models, changes in one object may be propagated to other objects unnecessarily. In this paper, we propose an efficient version management model for software objects based on history of operations applied to software objects. Operations applied to objects are recorded in the operation history, and those are used to retrieve versions of a document. Because versions of objects are stored and retrieved using the operation delta, it is not required to compare versions of a document to extract delta during check-in process. In addition, it can manage changes of structure of objects efficiently because it supports not only object creation, deletion, and update operation but also object move operation.

This paper presents a fast feature extraction method for autonomous mobile robots utilizing parallel processing and based on OpenMP, SSE (Streaming SIMD Extension) and CUDA programming. In the first step on CPU version, the algorithms and codes are optimized and then implemented by parallel processing. The parallel algorithms are debugged to maintain the same level of performance and the process for extracting key points and obtaining dominant orientation with respect to key points is parallelized. After extraction, a parallel descriptor via SSE instructions is constructed. And the GPU version also implemented by parallel processing using CUDA based on the SIFT. The GPU-Parallel descriptor achieves an acceleration up to five times compared with the CPU-Parallel descriptor, but it shows the lower performance than CPU version. CPU version also speed-up the four and half times compared with the original SIFT while maintaining robust performance.

The latest version of commercial protector, Themida, has been updated, it is impossible to apply a normalized unpacking mechanism from previous studies by disable the use of a virtual memory allocation that provides initial data to be tracked. In addition, compared to the previous version, which had many values that determined during execution and easy to track dynamically, it is difficult to track dynamically due to values determined at the time of applying the protector. We will look at how the latest version of Themida make it difficult to normalize the API wrapping process by adopted techniques and examine the possibilities of applying the unpacking techniques to further develop an automated unpacking system.

Objectives Nijmegen Questionnaire is one tool used internationally to evaluate hyperventilation syndrome. However, there is a necessity of developing Korean version of the Nijmegen Questionnaire, as the questionnaire of the original one are written in English, marking it hard to apply for Korean patients. So as a first step, we conducted a cross-cultural translation of the Nijmegen Questionnaire into Korean and verification of content validity. Methods We translated the Nijmegen Questionnaire into Korean up to guidelines of cross-cultural adaptation. We conducted a survey with 45 subjects to get content validity, using the translated questionnaire. Results About the translated Nijmegen Questionnaire, 28 out of 45 subjects replied that they had no difficulty understanding them, while 17 were pointed out ambiguous items and 7 offered ideas about ambiguous expressions of them. Upon further examination of five Korean Medical doctors, one sentence was additionally modified in the translated version. Conclusions We translated and adapted cross-culturally the original Nijmegen Questionnaire to develop a Korean version in accordance with internationally accepted guidelines. Then we conducted a survey for content validity with the translated questionnaire and gathered opinions from those questioned. After going through some examining and correcting procedures based on the opinions, we finalized the Korean version of Nijmegen Questionnaire. It will also require a follow-up verification process to prove reliability and validity of the final version of the Korean version of Nijmegen Questionnaire.

Rapid computing environment, change of the application structure, and various user demand will increase the demand of the software development. Version control is helpful to improve productivity using delta, and useful to establish component from existing data of source code. This paper presents the design and implementation of the version control system. which is composed of retrieval system and delta management system. In retrieval system, vanous retrieve methods arc proposed. This methods provides the process methodology with filename, content, size and date. Various retrieve methods arc important for the effective delta management. Meta data can be easily composed for the delta management by these methods. Compared with other systems, this implemented version control system has some advantage. First, for delta management, version maintenance for delta management becomes easier by integrating the forward and back-ward methods. Second, delta managent part of a project is to unite the forward and backward method. the effieiency of this system is to increased in management. Also, this system supports a thechnique of using the database and files for project repository and makes the version management more effective.

Background and Objectives: Cardiff Acne Disability Index(CADI) is one tool used internationally to measure the quality of life of acne sufferers. There, however, is a necessity of developing Korean version of CADI, as the questionnaires of the original one are written in English, making it hard to apply for Korean patients. So as a first step, we conducted a cross-cultural translation of CADI into Korean and verification of face validity. Methods: After properly translating CADI questionnaires into Korean up to guidelines for cross-cultural adaptation of health related quality-of-life measures, we conducted a survey with 122 undergraduates to get face validity, using the translated questionnaires. Results: About the translated CADI questionnaires, 86 out of 107 undergraduates replied that they had no difficulty understanding them, while 21 offered ideas about ambiguous expressions of them. Upon further examination of two oriental doctors, two sentences were additionally modified in the translated version. Conclusions: Firstly, we created the Korean version of CADI, one of the most effective methods in the world to measure acne sufferers' quality of life, by properly translated the original version into Korean. Then we conducted a survey for face validity with the translated questionnaires and gathered opinions from those questioned. After going through some examining and correcting procedures based on the opinions, we finalized the Korean version of CADI. It will also require a follow-up verification process to prove credibility and validity of the final version of Korean CADI.

Works that improve the process and notify the improved process, the product and the change of tasks to all users are essential in achieving project. Existent project management tools support the definition and the change of project activities, and configuration management tools support version check, workspace management. build management. etc. It costs too much to buy each tool. as well as, it is burdensome to learn usage for various tools. Therefore the web-based integrated tool is proposed to manage the process and artifacts at a time in this paper. The proposed tool defines component based development process model. and achieves recording of process progression, processing the request of change, reporting the progression of each task, product registering and change, version recording, artifact or form search, etc. using ebXML. Furthermore, the stakeholders get the systematic management and standardization by sharing information that are necessary in process achievement and configuration management in distributed environment using the integrated management tool.

The ebXML (Electronic Business using eXtensible Markup Language) Specification Schema is to provide nominal set of specification elements necessary to specify a collaboration between business partners based on XML. As a part of ebXML Specification Schema, BPSS (Business Process Specification Schema) has been provided to support the direct specification of the set of elements required to configure a runtime system in order to execute a set of ebXML business transactions. The BPSS is available in two stand-alone representations, a UML version and an XML version. Due to the limitations of UML notations and XML syntax, however, current ebXML BPSS specification is insufficient to specify formal semantic constraints of modeling elements completely. In this study, we propose a classification schema for the BPSS semantic constraints and describe how to represent those semantic constraints formally using OCL (Object Constraint Language). As a way to verify a Business Process Specification (BPS) with the formal semantic constraint modeling, we suggest a rule-based approach to represent the formal constraints and to use the rule-based constraints specification to verify BPSs in a CLIPS prototype implementation.

Purpose: This study examined the validity and reliability of the Korean version of the Revised Process of Change for Weight Control Scale (POC-WCS) in adults with metabolic syndrome. Method: A methodological research design with an exploratory factor analysis for validity and correlational coefficients for reliability was used. The Korean version of the Revised POC-WCS was translated into Korean and a translation equivalency was obtained. It was tested with one hundred and fifty-one obese adults with metabolic syndrome in a university hospital. The data were analyzed using Cronbach's alpha and Guttman coefficients and a principal component factor analysis with SPSS/WIN 12.0. Result: The factor analysis identified eight factors explaining 64.7% of the total variance. The Korean version of the Revised POC-WCS included stimulus control (9 items), dramatic relief (6 items), reinforcement management (6 items), helping relationships (4 items), consciousness raising (3 items), self liberation (3 items), self reevaluation (3 items), and social liberation (4 items). The internal consistency was acceptable with Cronbach's alpha (.94) and Guttman coefficient (.92). Conclusion: The Korean version of the Revised POC-WCS had adequate validity and reliability in adults with metabolic syndrome. It can be used to assess the strategies and processes for weight control in a variety of populations with obesity.
