The test instrument utilized to diagnose and evaluate a trainee's ability are necessary for an effective information literacy education. Nevertheless, there is a lack of a standardized test instrument to comprehensively measure students' information literacy. The purpose of this study is to develop a standardized test instrument to evaluate the information literacy of middle school students, and to verify the reliability and validity of the test instrument. For this purpose, this study selected factors that can show the information literacy and developed an information literacy test framework that was designed based on Guilford's SOI model and Meeker's SOI-LA test. The test instrument that was developed through this study is a 30-item Web-based multiple-choice test. This study administrated tests in middle school students (794 students joined), and analyzed difficulty, reliability, discrimination index, validity of tests, and reviewed tests items to qualify the standardized test. The cutoff score was also decided when using these tests as a diagnostic information literacy assessment.

Information communication authority module software contains various functions and services. A software test is the only acceptance test step. Recently, however, all development steps have become important. In particular, the software acceptance step is very high, and a study of the effective use of limited time and resources on acceptance step is needed. This study examined the efficiency of the Test Design Technique for Software Test. The proposed Test Design process was applied to the domain systems of info-communication and the degree of improvement was measured. This paper establishes Software Test design process Infrastructure based on the developed software.

Software testing is an important phase as it ensures the software quality. The software testing process comprises of three steps: generation, execution, and evaluation of test cases. Literature claims the usage of single and multiple 'Unified Modeling Language' (UML) diagrams to generate test cases. Using multiple UML diagrams increases test case coverage. However, the existing approaches show limitations in test case generation from UML diagrams. Therefore, in this research study, we propose an approach to generate the test cases using UML State Chart Diagram (SCD), Activity Diagram (AD), and Sequence Diagram (SD). The proposed approach transforms UML diagrams into intermediate forms: SCD Graph, AD Graph, and SD Graph respectively. Furthermore, by integrating these three graphs, a System Testing Graph (STG) is formed. Finally, test cases are identified from STG by using a traversal algorithm such as Depth First Search (DFS) that is an optimization method. The results show that the proposed approach is better compared to existing approaches in terms of coverage and performance. Moreover, the generated test cases have the ability to detect faults at the unit level, integration, and system level testing.

Regression testing is a very costly process performed primarily as a software maintenance activity. It is the process of retesting the modified parts of the software and ensuring that no new errors have been introduced into previously tested source code due to these modifications. A regression test selection technique selects an appropriate number of test cases from a test suite that might expose a fault in the modified program. In this paper, we propose both a regression test selection and prioritization technique. We implemented our regression test selection technique and demonstrated in two case studies that our technique is effective regarding selecting and prioritizing test cases. The results show that our technique may significantly reduce the number of test cases and thus the cost and resources for performing regression testing on modified software.

This study was performed to evaluate the effectiveness of music therapy as one of the psychiatric nursing intervention tools, with addtional information in relieving anxiety during the procedure. Data were collected through nonequivalent pre-and post tests from July 1, 1998 to September 30 1998 in 90 patients (test group A: 28 patients, test group B: 27 patients, control group: 33 patients) who were hospitalized in DongSan Medical Center in order to have cardiac catheterization. The Subjects were informed by educational videos, which were modified according to the sensory information of the 10 study patients. They were based on the informative booklet by Kim keum-soon (1989). The procedural information was also modified according to the hospital`s customs. Provided the music for patients suitable to their tastes, and measured their blood pressure, heart rate, the degree of anxiety using the Spielberger`s measurement device of anxiety, and behavioral response of Finesilver`s. The statistical significance was analyzed using chi-square test and ANOVA. The results of this study were as follows : Hypothesis 1 : There are significant differences in the degree of anxiety among test group A, Test group A was provided only information, Test group B was provided information and the control group was provided neither. Hypothesis 2 : There are significant differences in systolic blood pressure among test group A, test group B, and control group.: non-significant. Hypothesis 3 : There are significant differences in diastolic blood pressure among test group A, test group B, and control group.: significant(F=1.31, p=.27, interaction; F=3.80, p=.00). Hypothesis 4 : There are significant differences in heart rate among test group A, test group B, and control group.: non-significant. Hypothesis 5 : There are significant differences in behavioral responses among test group A, test group B, and control group.: significant(F=10.05, p=.00). Further validation study is required with other subjects and other settings.

In the case of an agile-based project, it was inadequate to perform a comprehensive inspection and evaluation on the establishment and operation of an information system by performing audit only with the audit and inspection elements provided by the existing information system audit and inspection system. In particular, in the case of the test activity area, it was necessary to improve the test activity audit check items to comprehensively check the agile-based development process by applying the existing audit system. To this end, a test activity improvement check model of the agile methodology audit model was presented by applying the repetition concept, a characteristic of the agile methodology. In order to empirically verify the model of this study, a survey was conducted for auditors and designers/developers who have experience in performing agile-based projects and auditing information systems. As a result of the questionnaire on the integrated test and system test in the test stage, more than 70% of the respondents were found to be suitable. More than 80% of the respondents judged that it was appropriate as a result of the questionnaire on "improvement and regression test progress according to integrated test and system test results" and "integrated test and functional actions of components and subsystems".

Interoperability tests are required to determine whether network-based defense systems successfully share and exchange certain services, information, and data. We must examine various aspects of interoperability. The DITA (Defense Information Technical stAndard) is the basis for interoperability. However, DITA is being applied to the defense system in a state that the standard test methods and procedures are not established. And there is no test method and procedure of the DITA well applicable to military weapons systems or information systems. Therefore, in this paper, we propose a framework that includes procedures, methodologies, so as to test whether a standard is applied to the DITA in terms of Standard Conformance Test.
