시스템 개발의 성공과 실패는 요구사항 정의의 명확함에 따라 좌우된다고 해도 지나침이 없다. 요구분석은 요구분석을 수행하는 프로세스 측면과 요구사항을 정의하는 방법적인 측면으로 나눌수 있다. 프로세스 측면은 점증적으로 요구사항을 명확하게 정의하기 위한 것이며, 방법적인 측면은 논리와 근거를 갖춘 형태로 요구사항을 정의하기 위한 것이다. 즉, 요구분석 단계와 요구사항 정의 방법이 요구된다. 본 논문에서는 이벤트 프로세스 모델링의 요구분석 5단계와 요구사항 변경을 예방하는 방법을 제시한다. 요구분석 완료 기준을 제시하고, 이벤트와 프로세스 방법으로 요구사항을 정의하는 방법을 설명한다.

This study aims to develop the model of needs analysis for lifelong education program in order to verify social needs as well as personal needs. The overall process of this study is as follows. Firstly, a questionaire based on six mode classification of lifelong education program was invented in order to apply to program development. Secondly, a questionaire was designed to evaluate personal needs and social needs simultaneously. Thirdly, t-test, needs analysis of Borich model, and the Locus for Focus model were conducted with a view to analyze the difference between personal needs and social needs. As a result, there showed the categories of education which are high in both personal and social needs, whereas a category like certification program is higher in social needs rather than in personal needs. The results represent the necessities of promoting programs which are high in social needs even if there is no personal needs. Therefore the needs survey and the needs analysis need to be conducted to find out not only personal needs but also social needs.

요구사항 추출 단계에서 고객의 요구의 일부가 반영되지 않거나 명확히 기술하지 않은 요구사항은 개발단계에서 많은 수정 작업이 요구되고, 심지어 그 프로젝트가 실패하게 되는 요인이 된다. 이와 같은 요구사항의 문제로 인한 추가적인 비용은 전체 개발비용의 30~50%나 소요된다(Boehm 과 Papaccio 1988). 하지만 요구사항 추출 단계에서 고객이 원하는 요구를 가능한 많이 추출하고 검증함으로써 추가적인 변경으로 인한 개발비용의 비용을 줄일 수 있다. 고객의 요구를 정확히 반영하기 위해서는 요구사항 추출 과정에서 고객의 참여가 매우 중요한데 본 논문에서는 성공적인 요구사항 추출 및 검증과 명세를 위해 사용자의 참여를 높이기 위한 웹 기반 요구사항 추출 도구를 소개하고 명확한 요구사항을 표현할 수 있기 위해 다이어그램을 통합한 요구사랑 관리도구를 제시한다.

소프트웨어 개발에서 나타나는 많은 오류는 요구 사항에 대한 정확한 이해의 부족에서 기인된다. 따라서 분석 단계에서 요구사항을 정확하게 나타내는 활동은 전체 소프트웨어의 신뢰성에 큰 영향을 미치게 된다. 요구 검증은 요구 분석 활동에서 산출되는 정보가 요구 문서의 정보를 바르게 나타내는가를 검증하는 활동이다. 본 연구에서는 객체 지향 소프트웨어의 개발에서 요구 검증을 수행하기 위해 OFL(Object-oriented Formal Language)과 질의 추출을 적용하였다. OFL은 객체 지향 형식 상태변이사항(Formal state transition specification)으로 형식 언어가 기자고 있는 명확성을 유지하며 분석 활동의 결과를 체계적으로 제시한다. 이러한 결과와 요구 문서와의 비교를 위하여 질의 추출이 수행된다. 이는 질의를 통하여 요구 문서에서는 나타나는 정보를 체계적으로 정리하여 개발 의뢰자가 제시한 요구 사항과 개발자가 제시하는 요구 사양간에 일치성과 완전성이 존재함을 검증한다. 이러한 요구 검증은 요구 사양의 신뢰성뿐만 아니라 개발되는 소프트웨어의 신뢰성을 향상시킨다.

The purpose of this study is to examine Pro-environmental consumer educational needs in the middle school. The data for the analysis are collected by the structured questionnaires. The data for 426 middle school students living in Seoul are analyze using descriptive statistics and One-way ANOVA. The following is a summary of major findings. : 1) The needs for the middle school students for the pro-environmental consumer education are high. The content showing the highest educational need is "The purchasing behavior of pro-environmental goods and services". 2) The sex of students. the experiences of taking 'Environment class', and types of housing are the factors affecting 'The pro-environmental consumer education needs' of the middle school students.

Background: It is important to provide health education to students to ensure a healthy life. Using the internet for health education may be a way to overcome the practical barriers to health education such as time and content. This study was conducted to investigate the demands for health education using the internet. Subjects and methods: Six hundreds and twenty-four and male female students in middle and high schools, who lived on Gyeongju-si and Seongju-gun in Gyeongsangbuk-do province, were interviewed by means of structured questionnaires, from March 5 to March 28, 2003. Results: More than 90% of the subjects had their own computers, and nearly 38% of those possessing their own computers had accessed internet sites related to health and medicine. Middle school students and in particular, female students were more desirous for health education through e-mail. Regarding content, the three major topics which the respondents wanted to learn about were healthy lifestyles, growth and development, and disease prevention. In terms of the interval for providing educational materials, over half of the students wanted information once a week. Most of the students wanted to have the quantity of the material be one page. In addition, there were numerous additional topics requested by the students such as sleep and health, contraception and family planning, safety education, cancer prevention, emotional instability of juveniles, the utilization of medical care facilities, stress management, etc. Conclusion: The students had a desire for health education through the use of e-mail, and methods and materials should be developed for appropriate health education using the internet.

In this paper, for the purpose of preparing some fundamental data on the development of the eye-health education program and conducting a practical application, the degree of request for the eye-health education were investigated by surveying 304 undergraduate students. The relationship between the degree of request for the eye-health education and sex, the division of major, and the experience of eye-health education was examined by SAS and $X^2$-test of questionnaire. The degree of request of undergraduate students for the eye-health education was as high as 86.51%. There was no statistical significant difference dependence on their experience of the eye-health education or their sex. There was significant difference dependence on their major. Specially, the degree of request of natural science, medical and health science majors was higher than any other majors. Consideration on the eye-health education should be required to meet the request of it.

The purpose of this research is to analyze training needs for skill assessor's competency of vocational education teachers in Korea. This research was conducted based on Russ-Eft's competency model for skill assessor. Data were gathered from 234 vocational education teachers over the country, and final respondents were 158 males and 73 females. As a result of analysis, reliability for expert (needs score 2.51), establishment for assessment management plan (needs score 2.11), management plan (needs score 2.08), and effective collaboration (needs score 2.07) have high developmental needs. On the other hand, recognition of a variety intention (needs score 1.01), observation of ethical standard (needs score 1.24), and personal relationship (needs score 1.76) have low developmental needs.

Requirements are very important to model software architecture. Requirements are divided into functional and quality requirements. Functional requirements are pinpointed subsystems and components. Quality requirements affect the structure of architecture. Thus requirements are essential to understand clearly in order to design software architecture. This paper focuses on a quantitative approach to requirements analysis for modeling architectures. In our proposal, functional requirements are quantified through calculating each priority of components. Quality requirements are quantified through calculating the correlation degree between components and quality attributes. The proposed method is implemented by DRAMA (Domain Requirements Analysis for Modeling Architectures), which fully supports our approach and are developed in Java environments. Our proposal is validated to apply some industrial examples.
