Web-based information resources should be managed and used methodically in the same manner as the paper-based resources are managed and used. It is necessitated by the prevalence of web-based delivery of a variety of information. To develop a web-based digital collection, it is critical to establish a set of standardized evaluation criteria for web-resources. The evaluation criteria needs to include authority, trustworthy, reliability, functionality, relatedness, accessibility, structure, design, user support, and security related matters. However, it is also necessary to have certain flexibility to either emphasize or include particular evaluation criteria to reflect varying characteristics of the web resources especially for the purpose of developing an effective digital collection. In addition, it is essential to review the evaluation criteria with respect to value, demand, duplication prevention, and intellectual property, which are relevant to the web-based digital collection development. Finally, various strategies were suggested as means to develop more effective web-based digital resource collection. These strategies include organizing a selection committee to ensure the objectivity and consistency in web-resource evaluation; developing a model for web-based digital resource collection; sharing new standards, protocols, markups, and metadata with other digital libraries; and developing user-centered digital resource collection.

Deficiencies are present in records management during the production stage of long-term electronic records preservation. As such, this study seeks to address these issues by introducing Cloud On-Nara System (On-Nara Document 2.0) at records management sites and providing various systems and linked services. In particular, the factors that degrade the continuity of long-term preservation in the records management process, from the production to the utilization of electronic records, in On-Nara Document 2.0 were identified, and the causes were analyzed in compliance with ISO 15486-1:2016 and the Public Records Act. As a result, in redesigning the records management procedure, the organization of the records management hub between systems and the conversion of the document preservation format for long-term preservation were proposed. Moreover, the application of consistent production format selection criteria and the reinforcement of the production and management of granular metadata were recorded. These measures were proposed in an effort to reestablish management methods.

This study was undertaken to investigate the influence of teamwork skill and decision making competency on nursing work performance. A total of 170 nurses more than one years working experience were recruited from two university hospitals. Data were collected during March, 16 to 25, 2016 using a structured self-report questionnaires. Data were analyzed using the IBM SPSS/WIN 21.0 program. Teamwork skill and decision making competency for nursing work performance showed significant positive correlation. The significant predictors of nursing work performance among nurses were total clinical experience (${\beta}=.23$, p<.001), teamwork skill (${\beta}=.61$, p<.001) and decision making competency (${\beta}=.13$, p=.015). These variables explained 66% of the variance in nursing work performance among nurses. The results indicate that nurses' teamwork skill and decision making competency are factors positively influencing on nursing work performance.

When, Software is developed, Applying development methods considering security, it is generated the problem of additional cost. These additional costs are caused not consider security in many developing organization. Even though, proceeding the developments, considering security, lack of ways to get the cost of handling the vulnerability throughput within the given cost. In this paper, propose a method for calculating the vulnerability throughput for using a security vulnerability processed cost-effectively. In the proposed method focuses on the implementation phase of the software development phase, leveraging static analysis tools to find security vulnerabilities in CWE TOP25. The found vulnerabilities are define risk, transaction costs, risk costs and defines the processing priority. utilizing the information in the CWE, Calculating a consumed cost in a detected vulnerability processed through a defined priority, and controls the vulnerability throughput in the input cost. When applying the method, it is expected to handle the maximum risk of vulnerability in the input cost.

The software is changed according to the changing businesses and the user requirement, it involves increasing complexity and cost. Considering the repetitive changes required for the software, replacement is more efficient than maintenance at some point. In this study, the replacement time was predicted using the service dissatisfaction index and replacement point assessment index by the software group for each task. First, fuzzy inference was used to develop the method and indicator for the user's service level dissatisfaction. Second, the replacement point assessment method was established considering the quality, costs, and new technology of the software. Third, a replacement time prediction technique that used the gap between the user service measurement and replacement point assessment values was proposed. The results of the case study with the business solutions of three organizations, which was conducted to verify the validity of the proposed prediction technique in this study, showed that the service dissatisfaction index decreased by approximately 16% and the replacement point assessment index increased by approximately 9%.
