With the development of the big data environment, public institutions also have been providing big data infrastructures. Public data is one of the typical examples, and numerous applications using public data have been provided. One of the cases is related to the employment insurance. All employers have to make contracts for the employment insurance for all employees to protect the rights. However, there are abundant cases where employers avoid to buy insurances. To overcome these challenges, a data-driven approach is needed; however, there are lacks of methodologies to integrate, manage, and analyze the public data. In this paper, we propose a methodology to build a predictive model for identifying whether employers have made the contracts of employment insurance based on public data. The methodology includes collection, integration, pre-processing, analysis of data and generating prediction models based on process mining and data mining techniques. Also, we verify the methodology with case studies.

In recent years, BIM services have been used in many construction projects. However, they are raising the question that there are many differences between what was initially proposed and what was actually done. In the IT sector, a method called as SLA is used to perform an assessment of the services delivered to the IT service project. In this respect, this study intends to introduce this method into building construction projects to use BIM in order to propose evaluation criteria and the evaluation process for SLA-based BIM service. The BIM service assessment process and criteria presented are judged to help introduce consistent and systematic BIM services in construction projects.

This paper aims to propose a cost-based mechanical, electrical, and plumbing(MEP) coordination process using building information modeling(BIM). The proposed process can help project participants eliminate identified clashes between the MEP elements, analyze trends relating to MEP costs during the coordination process, and share their findings. MEP quantity-related information extracted through BIM was integrated with the cost database and schedule information. To check the applicability of the proposed process, it was applied to a construction project in South Korea. Through the application of the proposed process, MEP-related cost was reduced.

It is rather difficult to improve flight control computer(FLCC) hardware(H/W) development schedule due to lack of commercial off-the-self(COTS) tools or target specific tools. Thus, it is suggested to develop an enhanced process utilizing modeling, simulation and virtual reality tools. This paper presents H/W design process enhancement tool(PET) for FLCC design requirements such as FLCC input/output(I/O) signal flow, I/O fault detection, failure management algorithm, circuit logic, PCB assembly configuration and installation utilizing simulation and visualization in virtual space. New tool will provide simulation capability of various FLCC design configuration including shop replaceable unit(SRU) level assembly/dis-assembly utilizing open flight format 3-D modeling data.

The purpose of this study is to analyze and remedy the irregular rework problems in shipbuilding industry. We collected and refined the rework event log of the SAP (ERP) outsourcing company of SPP shipbuilding. The process discovery and analysis were performed by fuzzy mining, pattern analysis and bottle neck analysis among process mining methods. The reworking of SPP shipbuilding was found to cause production rework and design change rework as ship owner 's requirement, design improvement, and field work were also causes of immaturity. In addition, method of case analysis result should be carried out in order to prevent PB(ship painting)-2A(ship owner request)-P1(re-work of production) which is the most common pattern in rework process. First, in the shipbuilding industry, the reworking process model and the analysis of the cause of rework contributed to prevention and minimization of rework, productivity improvement and cost reduction. Second, the process mining methodology is analyzed and the guidelines for future research are presented. Finally, it has a significance in that it contributes to improvement of business ability by systematically showing process model, problems and causes to enterprise managers.

Component-based Development is gaining a wide acceptance as an economical software development paradigm to develop applications by utilizing reusable software components. Well-defined interface manages coupling and cohesion between components, minimizes the effect on the user in case of component evolvement, and enhances reusability, extendibility and maintainability. Therefore, study on systematic development process and design guidelines for component interface has been required since the component has been introduced. In this paper, we propose three types of interfaces based on software architecture layers and functionality types； Provided Interface which provides functionality of a component, Required Interface which specifies required functionality that is provided by other components, and Customize Interface which tailors the component to customer's requirement. In addition, we suggest design criteria for well-designed interface, and systematic process and instructions for designing interface. We firstly cluster operations extracted from use case model and class model to identify Provided interfaces, and design Customize interfaces based on artifacts for variability. We also specify Required interfaces by identifying dependency among interfaces. Proposed interface design method provides traceability, throughout the component interface design. And furthermore, proposed guidelines support practical design for high quality component based on a case study.

In recent years, hoping the interaction of individuals and rather than software development process and tools, and customers want software that works first, rather than a comprehensive document, in cooperation with the customer, rather than the developer negotiate a contract, to each other stick to the plan I think even more so than the value that corresponds to the change. In view of this, software development is given the autonomy and motivation to project team rather than process-oriented and have a passion and vision and human relations oriented management approach is required. In recent years, increasing the productivity benefits of agile development processes, improved quality, efficiency and customer satisfaction as is demonstrated in the methodology selected to promote the project, attention was given to the experts. Contemporary demands with regard to the methodology chosen to meet your needs, in this paper in the organization, and to solve the problems of product-based Cross functional team proposed methodology Feature Team model, this model is an organizational Cross functional team and the team is not the outcome (product) basis, were examined for the model that points to progress the development across multiple product as a functional unit, value-plan through the driven agile technique-based model and proposed a difference. And the domain analysis, required extraction by conventional JAD (joint application development) meeting the targets for the object-oriented modeling, in modeling and organize, review, aware in advance and the UML Structure and Behavior Diagrams and proposed to proceed with the project.

대표적인 시맨틱 웹 서비스 발견 기술은 OWL-S와 MIT의 Process Handbook이 있다. 그러나. OWL-S는 개발 초기 단계이기 때문에, 아직 효과적인 웹 서비스 발견을 제공하기에는 몇 가지 제약 조건을 가지고 있다. 예를 들어. 정보 전송을 위한 제악 조건과 실행에 따른 상태 변환 정보를 정의하고 있지 않다. 또한. 사용자가 원하는 프로세스들의 시맨틱 정보들을 정의하고 있지 않다. 반면, MIT Process Handbook은 OWL-S와 같이 서비스 모델에 대한 상세한 정보들을 정의하고 있지 않아, 서비스 작성에 필요한 서비스들을 찾기가 어렵다. 그러므로, 본 논문에서는 Topic Maps 기반의 TM-S(Topic Maps for Service)를 제안하였다.

The SP quality assessments from national IT industry promotion agency of Korea(NIPA) assesses ability of software development process. And the SP quality assessments is getting popular over the nation. But, in the SP quality assessments, there is no concern about security attribute. In this paper new secure process base on ISO 27001 is proposed for the organization that is already passed SP quality assessments. This process can detect security threatening factors and gives chance to protect those factors. Furthermore, since detected security weaknesses can be used as a measurement, the system can be managed in aspect to security attribute.

공학적 기반에 의한 소프트웨어 품질 개선에 대한 노력은 역량 성숙도 모델(CMM)에서 특정 프로세스가 정확하게 정의되고, 관리되고, 측정되고, 통제되고, 효과적이게 될 수 있는 방향으로 진행되고 있다. 또한 소프트웨어 엔지니어링 분야에 국한되지 않고 시스템, 인력 분야 등에서의 다양한 역량 성숙도 모델을 바탕으로 프로세스 개선이 이루어지고 있다. 그러나 이는 중복성 등 관리상의 문제가 발생하여 이를 통합(CMMI)하려는 연구가 이루어졌다. 이에 게임 개발 프로젝트의 CMMI 적용 방안을 모색하고 기대되는 개선효과를 논한다.
