웹/인터넷의 등장 이후, IT환경에서는 웹 사이트 수, 사용자 수의 폭발적인 증가로 하드웨어와 소프트웨어의 구성이 복잡하게 되었다. 적용 업무의 장애가 발생시에 신속하고 정확한 장애원인을 파악하기가 어려워진다. 따라서, 웹 어플리케이션에 맞는 전문적인 성능 테스트와 성능 관리가 필요하게 된다. 본 논문에서는 웹 어플리케이션의 특성에 맞는 성능 시험 평가 모델을 제시한다.

미국정부는 공공정보의 상용화와 관련한 주도권을 적극적으로 민간기업에 이양함으로써 공공정보를 통한 고부가가치 창출에 성공을 거두고 있다. 미국 법률은 공공정보의 상용화를 보장하고 있으며, 이는 공법상 공공정보 관련 근거법은 존재하지만 실제로 공공정보의 상용화를 위해 필수적인 공공정보 활용 권리는 찾아보기 어려운 우리나라의 법률 실정과는 매우 대조적이다. 민간의 공공의 파트너십을 통한 공공정보의 상용화 모델은 정부 업무의 효율성 증진과 국민의 알권리 충족을 만족시키고, 참여 민주주의를 확대하고 경제적 측면에서도 큰 기대효과를 지니고 있다.

웹(WWW)기술은 기존 클라이언트 서버환경의 정보 시스템을 그대로 활용하면서 TCP/IP프로토콜을 이용하여 인터넷기반의 분산시스템 환경을 제공한다. 웹 어플리케이션을 개발할 경우 기존의 어플리케이션 개발방법과 더불어 하이터미디어 형식으로 개발되어 지기 때문에 하이퍼어플리케이션 개발방법론의 적용이 요구되어진다. 그러나 단지 정보획득의 목적으로 사용되던 기존에 제안된 하이퍼미디어 개발방법론들을 웹 어플리케이션 개발에 그대로 적용하기는 미흡하다. 따라서 본문에서는 웹 어플리케이션 개발 과정중 논리적인 업무 프로세싱작업을 지원하면서 주요작업이 되는 하이퍼미디어 사용자 인터페이스 설계단계를 확장 지원하는 정보 구조 모델 방법론과 개발 프로세싱 절차를 제안한다.

Block chain technology is one of the core elements for realizing the 4^th industrial revolution, and many efforts have been made by government and companies to provide services based on block chain technology. In this study we analyzed the benefits of block chain technology for EVMS and designed EVMS block chain platform with increased data security and work efficiency for project management data, which are important assets in monitoring progress, foreseeing future events, and managing post-completion. We did the case studies on the benefits of block chain technology and then conducted the survey study on security, reliability, and efficiency of block chain technology, targeting 18 block chain experts and project developers. And then, we interviewed EVMS system operator on the compatibility between block chain technology and EVM Systems. The result of the case studies showed that block chain technology can be applied to financial, logistic, medical, and public services to simplify the insurance claim process and to improve reliability by distributing transaction data storage and applying security·encryption features. Also, our research on the characteristics and necessity of block chain technology in EVMS revealed the improvability of security, reliability, and efficiency of management and distribution of EVMS data. Finally, we designed a network model, a block structure, and a consensus algorithm model and combined them to construct a conceptual block chain model for EVM system. This study has the following contribution. First, we reviewed that the block chain technology is suitable for application in the defense sector and proposed a conceptual model. Second, the effect that can be obtained by applying block chain technology to EVMS was derived, and the possibility of improving the existing business process was derived.

Evaluating the work process of the organization is necessary to improve efficiency and make high quality of results. As size of construction projects are bigger, it is also applied to design firm. By applying efficient process, design team can reduce rework and waste. To make systematic process and keep a continuous progress, process evaluation is required. On this study, CMMI(Capability Maturity Model Integration) concept is benchmarked. Originally CMMI is suggested to evaluating capability of work process of Soft Ware developing organization by SEI(Software Engineering Institute). From CMMI system, direction of making evaluating method of design project performing team is drove. After worked out the evaluation method of capability maturity of process in design team, it could contribute making progress in the design process and satisfying client.

Recently, the importance of visual analytics has been recognized in the field of business intelligence. From the view of business intelligence, visual analytics aims for acquiring valuable insights for decision making by interactively visualizing a variety of business information. In this paper, we propose a treemap-based method for visualizing work-sharing relationships among business process performers. A work-sharing relationship is established between two performers who jointly participate in a specific activity of a business process and is an important factor for understanding organizational structures and behaviors in a process-centric organization. To this end, we design and implement a treemap-based visualization tool for representing work-sharing relationships as well as basic hierarchical information in business processes. Finally, we evaluate usefulness of the proposed visualization tool through an operational example using XPDL (XML Process Definition Language) process models.

This study was conducted to identify the factors that affect the nursing performance. These factors are general characteristics, mentoring function and organizational citizenship behavior. A survey was conducted on 163 nurses working for general hospitals in South Korea from December 2 - 30, 2015. The data was analyzed using the SPSS WIN 21.0 program to analyze the descriptive statistics, independent T-test, ANOVA, Scheffe test, Pearson's correlation, and multiple regression. The factors affecting the subject's nursing performance were altruism (${\beta}=.46$, p<.001), courtesy (${\beta}=.12$, p=.047), belonging to the sub areas of the organizational citizenship behaviors, role modeling function (${\beta}=.31$, p=.001), career develop functions (${\beta}=-.22$, p=.018), belonging to the sub areas of the mentoring function, and position (${\beta}=.24$, p<.001). The results of this study are expected to provide basic data to improve the nursing performance.

As more than 80 percent of tasks within corporations are performed through information systems, they have become large in scale and complicated, which make the range of the system users diverse and specialized. and as recent corporate strategies focus on the real-time environment in businesses, the organizational structure within companies tend to show frequent changes. In order to ensure the business continuity in this environment, the most important aspect is to prevent incompleteness of business by narrowing the gap of understanding of business process between the system users and the maintenance managers. In order to address this problem, this study suggests a modeling method that utilizes business scenarios reflecting actual business rules and procedures which ultimately transforms the optimized and standardized form of business scenarios into the actual software maintenance activities. This modeling method improves reusability and usability through the repeated feedback mechanism for modified software by leading to gradual fine-grained process. The feasibility of this is to be proven by applying the modeling method to the real business environment.

The development of smart devices has affected employees' working environments and their lives. However, using smart devices is causing employees to experience technostress. This study aims to investigate the effects of technostress in using smart devices on usage intention in an organization. Moreover, the study investigates the effect of employees' stress-coping methods on the intention to use smart devices. This study posits familiarity, use innovativeness, role ambiguity, system vulnerability, technological limitation, and ubiquity as the antecedents of technostress. Data collected from 317 users who have experience in using smart devices in organizations are empirically tested against a research model using the PLS graph. Analysis results show that role ambiguity, system vulnerability, and technological limitation significantly influence technostress. Moreover, users take up emotion-focused coping behaviors because of technostress. Emotion-focused coping behaviors affect usage intention in organizations. However, technostress and problem-focused coping behaviors do not directly affect usage intention in organizations.

지자체 GIS 정보화가 확산되어감에 따라 구축된 공간정보의 활용확산, 타 정보와의 연계 등의 요구가 증대되고 있으며 지자체 GIS 통합 연계는 지자체 정보화의 핵심으로 부각되고 있다. 그러나 많은 지자체에서는 도로, 상하수도 등 공간정보 수요가 높은 업무 분야를 중심으로 지자체 GIS 통합연계를 추진하고 있으며, 지자체 지리정보 담당부서의 중심으로 추진되고 있어 지자체 전 부서 대상의 공간정보 활용에 대한 한계가 있다. 이러한 한계를 극복하기 위해선 지자체 내 전부서에서의 공간정보 활용을 위한 지자체 GIS 통합연계 고도화 모델이 필요하다. 지자체 GIS 통합연계 고도화 모델은 지자체 지리 정보 담당부서 중심의 통합연계에서 확대하여 지자체 전 부서 및 국가적 차원에서의 협력체계를 고려한 모델로서 지자체의 수평적 수직적 통합연계 모델이다.
