  • 최근 정보화에 대한 성과평가는 투자성과에 미치는 효과를 정량적, 정성적으로 분석하여, 전통적인 투자 수익률에 근거한 가치평가방법의 한계를 극복하기 위한 다양한 성과평가방법이 응용되고 있다. 하지만 공공분야의 성과평가는 평가영역에 대한 정성적 평가 중심의 성과여부를 도출하는데 머무를 뿐, 정보화 품질을 향상시키는 데까지는 이르지 못하는 단점이 있다. 따라서 본 논문에서는 기존 공공분야 성과평가의 한계점을 개선하고 품질평가와 정량적 평가를 반영함으로써, 정보화 품질 향상과 평가결과의 객관성 및 신뢰성을 보장하는 통합성과평가모델을 제안한다. 그리고 정보화사업으로 추진된 행정정보DB구축사업을 대상으로 사업목적을 고려한 평가영역별 반영비율 및 가중치를 적용한 평가결과를 도출하였다.

  • KS and ISO have proposed several evaluation methods of conventional machine tools. Even though the accuracy of the tools can be evaluated with those methods, there are still no proper evaluation methods of high speed machining. Because it is hard to evaluate characteristics of high speed machining such as decrease of cutting temperature, cutting force, and reduced machining time. Therefore, new evaluation method for high speed machine should be developed. In this paper, several shapes of model have been proposed to evaluate cutting accuracy of high speed machine.

  • Waterproofing materials and construction methods have been developed and applied to various construction sites since the past. However, there many cases where the waterproofing performance is not satisfactory, leading to continuous water leakage. It has been observed that a key reason for this is because waterproofing method and material selection is not optimized in terms of the appropriate application area and environmental degradation factors. This paper proposes that future selection of waterproofing methods should consider the following evaluation criteria; 1) waterproof performance evaluation according to site conditions, 2) evaluation of construction method, 3) manufacturing and maintenance of waterproofing systems.

  • For Barrier-Free certification, the floor and ground surfaces must be finished with materials that are not slippery, flat, and have low-impact in fallis. However, the BF Certification Act does not provide specific methods to meet these regulations. In performance-based design, the responsibility of proving the performance rests with the building owner and architect, so quantitative evaluation indexes are needed to select suitable materials. Furthermore, changes in performance after completion should be checked periodically in 'As-Is' conditions. There are various methods for slips, trips and falls risk assessment, causing confusion for users. In this study, the results of previous studies on the evaluation methods of slips, trips and falls were considered closely, and each quantitative evaluation index that can be used in the new construction and maintenance phase was presented.

  • Objective : The authors investigate appropriate evaluation and surgical methods in treatment of the cerebral paragonimiasis accompanying epilepsy. Methods : Thirteen patients with the cerebral paragonimiasis accompanying epilepsy were included for this study. Preoperative evaluation methods included history taking, skin and serologic tests for Paragonimus westermani, neurologic examinations, computerized tomography, magnetic resonance imaging, amytal test, PET or SPECT, and video-EEG monitoring with depth and subdural grid electrodes. Seizure outcome was evaluated according to Engel's classification. Results : Surgical methods were temporal lobectomy including lesions in six, lesionectomy in five, and temporal lobectomy plus lesionectomy in two. Postoperative neurological complications were not noticed, and seizure outcomes were class I in 12 patients [92%], class II in one [8%]. Conclusion : In patients with a cerebral paragonimiasis accompanying epilepsy, further evaluation methods must be done to define the epileptogenic zone, and complete resection of the epileptogenic zone with different surgical methods should be performed for seizure control.

  • The purpose of this study is to apply to the phenomenological self-evaluation method in the social welfare agency. It means that the phenomenological self-evaluation method accepts "the reality" which occurs in the social welfare setting, and functions for the social worker to play dual role of practitioner-evaluator. This paper examines two dimensions of social work evaluation theory and practice. Firstly, this study is to investigate a trend of evaluation in social work setting, and seeks theoretical aspect of phenomenological self-evaluation method, with emphasis on the strength and limit of the positivism evaluation methods. Although qualitative evaluation was suggested to make an alternative to the positivism by qualitative researchers, they did not suggest the specific methods and roles of the practitioner-evaluator. In this study, two directions of the phenomenological self-evaluation method are suggested to overcome the limitations. which are "environment-relation self-evaluation" and "program-oriented self-evaluation". Secondly, the result of phenomenological self-evaluation studies for the social welfare community center program and organization in kangnam district from June, 1994 (Program-oriented self-evaluation) to march, 2000 (Environment-relation self-evaluation) are presented. the phenomenological self-evaluation study showed the expected outcome such as; reflective self-training, making a practice knowledge, enhancing service quality, and reinforcing the identity of social welfare profession.

  • Purpose: This study compared the relative importance of educational content, teaching methods, and evaluation methods in the patient assessment curricula of 119 emergency medical technicians (EMTs). Methods: First, we identified the educational content, training hours, and teaching and evaluation methods of the existing patient assessment curriculum based on the National Competency Standard learning module. Second, we surveyed 30 EMTs affiliated with 119 services using the Analytic Hierarchy Process (AHP) method. Subsequently, we compared the differences between the current curriculum and the AHP analysis results. Results: Currently in operation, the "Advanced EMT Course" comprises three learning modules: assessment of patient status, scene size-up and triage, and assessment using monitoring devices. Among these, content related to the assessment of patient status received the most allocated time and was deemed the most important according to the AHP survey results. Conversely, while less time was allocated to scene size and triage compared with assessment using monitoring devices, the former was assessed as more important than the latter in the AHP results. Furthermore, scenario-based team training and procedure-focused individual practice were evaluated as relatively important teaching methods, while practical examination using a checklist was deemed the most appropriate evaluation method for all learning content. Conclusion: To improve the patient assessment curriculum, we propose adjusting teaching hours and introducing new teaching and evaluation methods based on the results of relative importance. The proposed improvement plan will contribute to enhancing the competency of 119 EMTs.

  • Objectives: When a person speaks, voice problems usually include pain or discomfort and/or difficulties in terms of the pitch, the loudness and the quality of the voice. When patients with voice problems induced by stroke, Parkinson's disease, and systemic diseases involving the voice are examined, generally, of the Four Diagnoses (四診), a Diagnosis of Hearing can be used in current Korean medicine. The effects of acupuncture and herb medicine on voice problems have been reported for over 20 years. However, when it comes to improvements, objective and subjective evaluation methods need to be explained. Methods: Subjective methods for evaluating voice were studied through a literature search of old medicinal books containing Korean medicine diagnostics, and an objective evaluation method using Praat software is presented. Results: Korean medicine doctors analyze the patient's voice in clinical settings unconsciously on a daily basis. However, most voice diagnoses depend on the doctor's subjective evaluation. Voice qualities can be evaluated by using the Eight Principles (八綱), including Yin-Yang; the Five Elements (Phases); the Grade, Roughness, Breathy, Asthenic, Strained (GRBAS) score, and the Visual Analogue Scale (VAS) as subjective methods, and an acoustic analysis using the Praat program can be used as an objective method. Conclusion: A more complete voice examination can be achieved by using subjective and objective methods at the same time. For an objective explanation and management of patient's voice problems or systemic disorders, an objective method should be used in Korean medicine, which already has many subjective diagnostic methods. More research needs to be conducted, and more clinical evidence needs to be collected in the future.
