Data Envelopment Analysis (DEA) is a theoretically sound framework for performance analysis that offers many advantages over traditional methods such as performance ratios and regression analysis. Largely the result of multidisciplinary research during the last three decades in economics, engineering and management, DEA is best described as an effective new way of visualizing and analyzing performance data. Besides, overseas information technology companies have aggressively tried to enter the domestic market. In the age of globalization and high competition, it is imperative that the system integration (SI) companies need to introduce the performance evaluation models of SI projects, including Capability Maturity Model and Software Process Improvement and Capability Determination, to gain a competitive advantage. Therefore, it makes our research regarding evaluation of SI projects very opportune. The purpose of the study is not only to evaluate efficiency of each project by DEA but also to gain insight into various factors such as project complexity, team members' man-months structure, and process index(project management index) that link to the projects performance.

How can the educator help learners to learn? The old way was to tell learners as much as possible, passing on the educator's knowledge. Now the educator acts as a helper. She will organise experiences which allow the learners to do health behaviors, she may utilize instructional materials, she may write downsome questions for a group of learners to discuss. In all these ways the teachers is helping learning. Some educators feel that they must do all the talking themselves. They feel that they are not really teaching the learners some new information, but this is quite wrong. In fact if a educatorgives a lecture and learners do not learn, then the educator is talking not teaching. So the devlopment of instructional materials is much needed to be a learner education. And the selection of materials may be very important for the level of maturity of the learners in interest, complexity of ideas, opportunity for self-identification, speed of learners' ability to observe and length of concentration. Author studied the several instructional materials which can be utilized in the field of dental health education and also studied their values, limitations and considerations when they are used. The learning activities are poster, puppet, model, mock-up, specimen, flannel board, chalk board, bulletin board, psychodrama, role play, field trip, exhibition, laboratory method.

In engineering industry, technical documentation refers to any type of documentation that describes handling, functionality and architecture of a technical product. The intended audiences for product technical documentation is the end user, the administrator, service or maintenance technician. Competition and rapid technological evolutions have created pressure to release new and improved products on an increasingly frequent basis. As the technical capabilities of products advance, the technical documentation for those products is becoming longer and complex. The Darwin Information Typing Architecture (DITA) is and XML-based, end-to-end architecture for authoring, producing, and delivering technical documents. DITA is an OASIS standard that allows documentation groups to single-source document for multiple products and users, to automatically publish that documentation in several media formats including PDF and HTML, and to efficiently maintain and update that documentation. This paper study on the various implementation projects for technical documentation using OASIS DITA standard and examines the potential for using DITA as a solution for reconstructing existing technical documentation. Also We offer an incremental adoption approach to effectively implement DITA standard of technical documentation project for domestic firms, while reducing failures.

최근의 소프트웨어 시장에는 조직의 사업 목적 달성을 위한 성숙모델, 표준, 방법론 및 지침들이 개발되고 있다. ISO/IEC 15504와 CMMI등 모든 SPI 모델들은 숙련된 전문 심사원을 통하여 소프트웨어 프로세스의 능력수준을 결정한다. 그러나 숙련된 전문심사원이라 할지라도 프로세스 측정을 위한 체계적인 척도를 제공하지 않으므로 심사원은 심사대상 프로세스의 정량적인 수준 측정을 위하여 객관적이며 일치된 판단을 통해 프로세스를 평가할 수 없다. 본 논문에서는 ISO/IEC 15504와 CMMI의 핵심 프로세스들에 대하여 정량적이고 객관적인 측정을 위하여 척도를 설계하였고, 실험을 통하여 척도의 타당성을 분석방법을 이용하여 증명하였다. 이를 통해 객관적인 측정 절차와 척도의 사용을 통하여 효과적 SPI 활동을 기대할 수 있다.

소프트웨어 프로세스 개선의 효율을 높이기 위해 하나의 개선 모델을 사용하기 보다 둘 이상의 서로 보완 가능한 개선 모델의 통합 모델이 사용될 수 있으며, 그중에 하나가 CMMI(Capability Maturity Model Integralion)와 소프트웨어 식스 시그마의 통합 모델이다. 하지만 소프트웨어 식스 시그마 도구는 그 수가 많고 통계적 지식을 요구하므로 소규모 조직에서 모든 소프트웨어 식스 시그마 도구를 적용하는 것은 어려운 실정이다. 본 논문에서는 조직의 비즈니스 가치를 달성에 도움을 주는 소프트웨어 식스 시그마 도구를 선정하는 프로세스를 제시함으로 소규모 조직에서도 적은 비용과 빠른 성과로 인해 점증적인 소프트웨어 식스 시그마 도구의 도입을 통한 효율적인 CMMI의 구현이 가능케 된다.

Chlorophyll fluorescence has been researched for assessing fruit post-harvest quality and condition. The objective of this preliminary research was to investigate the potential of fluorescence spectroscopy for measuring apple fruit quality. Ultraviolet (UV) and blue light was used as an excitation source for inducing fluorescence in apples. Fluorescence spectra were measured from 'Golden Delicious' (GD) and 'Red Delicious' (RD) apples using a visible/near-infrared spectrometer after one, three, and five minutes of continuous UV/blue light illumination. Standard destructive tests were performed to measure fruit firmness, skin and flesh color, soluble solids and acid content from the apples. Calibration models for each of the three illumination time periods were developed to predict fruit quality indexes. The results showed that fluorescence emission decreased steadily during the first three minutes of UV/blue light illumination and was stable within five minutes. The differences were minimal in the model prediction results based on fluorescence data at one, three or five minutes of illumination. Overall, better predictions were obtained for apple skin chroma and hue and flesh hue with values for the correlation coefficient of validation between 0.80 and 0.90 for both GD and RD. Relatively poor predictions were obtained for fruit firmness, soluble solids content, titrational acid, and flesh chroma. This research has demonstrated that fluorescence spectroscopy is potentially useful for assessing selected quality attributes of apple fruit and further research is needed to improve fluorescence measurements so that better predictions of fruit quality can be achieved.
