As a result of the compulsory of information system audit and a rise in audit demand, the quality improvement of information system audit is being emphasized. However, since the current information system audit heavily depends on the auditor's experience, skill, and subjective judgments, it incurs distrust in the objectivity and reliability of audit results from audit interest person. Furthermore, so far research activities aimed at securing the objectivity and reliability of audits have not been adequately carried out. Therefore, this paper presents a quantitative method for information system audit evaluation in order to contribute to the quality improvement of overall information system audit through securing compliance, objectivity, and reliability of information system audit. The quantitative method is largely composed of two sectors, such as evaluation areas and items, scores calculation for evaluation items, and can generally apply the information system audit standard to information system audit evaluation.

In this paper to develop objective speech quality measure for CDMA telephone network environments, recent developed measures are investigated first. But those measures show low performances in CDMA telephone networks. To solve this problem, new objective speech quality measure adopting noise masking threshold is proposed and studied. To acquire better performance, scaled noise masking threshold calculation for speech signals is employed instead of conventional tone signals. To verify effectiveness of proposed method performance comparison experiments are carried out for CDMA telephone network speech databases, for the results proposed methods show improved performances compared to existing meaures.

The purpose of this study is to investigate the differences of science achievement between female- and male students in different assessment types, expecting the reconsideration of their scientific ability. to accomplish this purpose, the school science achievement score of 1,487 female- and male students in 2000 were analyzed from the perspectives of assessment methods and gender differences, achievement level and gender differences, and gender characteristics in correlation between each assessment type and total science score. The science achievement score in this study includes mi-term and final paper-and-pencil test in two semesters and performance assessment. The results are as follows. First, in the total science achievement score, whereas female students achieved significantly better than male counterparts in the 7th grade, there was no significant difference between two genders in the 8th and 9th grades. Second, as for the close-ended items, all students, regardless of their gender and grade, showed no significant difference. As for the open-ended items, whereas female students achieved significantly better than male counterparts in the 7th grade, there was no significant difference between gender in the 8th and 9th grades. As for the performance assessment, all female students, regardless of their achievement level, achieved significant better than male counterparts, which is very noteworthy. Third, in the uppermost achievement level, there was no significant difference not only in close- and open ended items but also in performance assessment. Fourth, male students' correlation between performance assessment and total science score was relatively higher than female students'. The result of this study, that female students did significantly better than male students in performance assessment, is interesting in that performance assessment is widely accepted as more reliable and valid method in measuring students' various ability than traditional paper-and-pencil test.

Today the domestic construction industries are changing. The bigger, higher and more professional are gradually the construction industries, the faster does the fusion into the other industries also undergone. It is gradually needed to estimate the process of the project in the construction industries through this tendency. Consumers or the owner gradually reify their needs and it is essential for an objective appraisal standard to estimate the accomplishment of the project because its level is raised. In this study the problem is understood through the analysis on the existing system of construction industries and it is indicated to new performance measurement system in construction project through the analysis on the influential factors including the qualitative analysis such as consumer satisfaction.

Remodeling is an architectural activity that transforms the existing state of specific building which has been aged and clichedinto new state overcoming those aged and cliched state. Remodeling can be a means to increase building's physical lifecycle and also a countermeasure to cope with the changes in use that are from social demand, use and technical development. The performance evaluation on the remodeling tenement shall be done by understanding the performance and state of the building before and after remodeling and then it shall represent the improvement in performance objectively by comparing the differences before and after remodeling. In this aspect, we performed basic research to conduct performance evaluation on the remodeling tenement by comparing and analyzing the performance evaluation and performance certificate systems of Korea and Japan in order to suggest objective evaluation system on the change of tenement building before and after remodeling.

The purpose of this study is to identify trends in the application of artificial intelligence by analyzing upper extremity movement assessment and artificial intelligence convergence research using a systematic literature review method. The research was conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Among the 380 articles searched in three databases, 8 articles were finally selected according to the selection and exclusion criteria. For the evaluation of upper extremity movement, motion performance evaluation, FMA, and ARAT were used. For quantification, data were extracted using various tools, and upper extremity movement classification, recovery prognosis prediction, and evaluation tool score were predicted using artificial intelligence. This study is meaningful in that it systematically reviewed studies that objectively evaluated upper extremity movement using artificial intelligence and identified the direction in which artificial intelligence is being applied. Based on this, the introduction of artificial intelligence technology in the assessment of upper extremity movements is expected to help objectively identify the intervention effect and the patient's recovery.

금년부터 국립공원 입장료가 폐지되며, 환경영향평가의 객관성과 공정성을 제고할 수 있도록 환경영향평가제도가 개선된다. 또한 자동차배출가스 배출허용기준이 선진국 수준으로 단계적 강화되며, 수도권 대기환경 개선을 위해 사업장 대기오염물질 총량관리제가 시행된다. 수돗물 수질검사 지점이 확대되며 수질 환경기준이 생태적 건강성 평가를 반영하는 수질 및 수생태계 환경기준으로 바뀌게 된다. 2007년부터 환경분야에서 달라지거나 새롭게 시행되는 제도를 분야별로 정리를 하였습니다.
