The current study aims to determine digital transformation (organizational, technical, and human resources) requirements at Saudi universities from Umm Al-Qura University faculty members' perspectives. The researcher used a quantitative approach based on the descriptive analytical design. To answer the questions of the study, the researcher used the questionnaire as a data collection tool. The questionnaire was sent electronically to faculty members working in colleges and institutes affiliated with Umm Al-Qura University in Makkah Al-Mukarramah, Saudi Arabia. The questionnaire consisted of the three dimensions of digital transformation: organizational; technical; and human resources requirements. The results showed that requirements related to human resources came first with an average of 2.25 then the organizational requirements with an average of 1.95, and in the last, technical requirements came with an average of 1.64. In addition, some suggestions were given by the participants (faculty members) related to the mechanism that could contribute to implementing digital transformation at Saudi universities. Likewise, at the end of the study, the researcher has given some suggestions related to the implementation of digital transformation requirements at Saudi universities.

The purpose of this paper is to suggest Korean regulatory requirements of railway drivers' qualifications. The qualification of railway drivers is one of major factors that should be managed to reduce human error induced incidents/accidents. We have collected those domestic/foreign cases for suggesting Korean regulatory requirements of railway drivers' qualifications. And we have analysed them to derive some regulatory requirements reducing human error. Finally, we have done preliminary FGI(focused group interview) to vitrificate and validate the regulatory requirements.

Korea Astronomy and Space Science Institute (KASI) has been developing one mobile and one stationary SLR system since 2008 named as ARGO-M and ARGO-F, respectively. KASI finished the step of deriving the system requirements of ARGO. The requirements include definitions and scopes of various software and hardware components which are necessary for developing the ARGO-M operation system. And the requirements define function, performance, and interface requirements. The operation system consisting of ARGO-M site, ARGO-F site, and Remote Operation Center (ROC) inside KASI is designed for remote access and the automatic tracking and control system which are the main operation concept of ARGO system. To accomplish remote operation, we are considering remote access to ARGO-F and ARGO-M from ROC. The mobile-phone service allows us to access the ARGO-F remotely and to control the system in an emergency. To implement fully automatic tracking and control function in ARGO-F, we have investigated and described the requirements about the automatic aircraft detection system and the various meteorological sensors. This paper addresses the requirements of ARGO Operation System.

Recently, the importance of user experience (UX) has been rapidly increasing. Its utilization is emphasized for development of systems, products, and services. User experience is widely used across industries including services, products, processes, society, and culture. Therefore, if it is unsatisfactory, it is likely to have a direct negative impact on the corresponding system, product, or service. The failure to analyze user experience causes significant damage to the project, which may lead to its failure or redevelopment; it is hence necessary to prioritize the verification of UX in the earliest stages of development. The requirements development stage, which is a preceding stage, is an appropriate stage for the verification of user experience because the identification of user needs is completed and prototypes can be implemented. In this paper, we proposed a systematic requirements development stage; it adds user experience verification activities to the requirements development stage, using the Honeycomb model, which is a widely used tool for verifying the overall UX. User experience verification was added to the existing requirements development activities, which consisted of three steps: model definition and requirements placement, discussions between external and internal stakeholders, and review by internal stakeholders. By easily validating the user experience through this systematic requirements development stage, we expect to minimize the damage to the project due to the failure of the user experience analysis and increase the possibility of success.

It is well known that the test and evaluation plan (TEP) is very crucial in the successful development of safety-critical systems. As such, this paper discusses an approach to the development of the TEP for a system that should meet safety requirements in the systems development process. It is studied how to incorporate the result of preliminary hazard analysis (PHA) in generating the safety requirements. It is also discussed how to deal with them when the system requirements (i.e., functions, performance, constraints, components, etc) and the safety requirements are integrated into one model. While doing so, we have constructed the required traceability among them, which is necessary and very useful when the safety requirements need to be corrected or be changed. The use of the traceability makes it possible to easily check out whether and how the safety requirements are properly incorporated in the system design process. Furthermore, without the verified traceability, the system cannot be changed or upgraded later. In order to implement the model on a computer-aided tool, we have constructed a database (DB) schema. As a result, the implemented model/DB allows to automatically generate TEP which can be used to measure the performance and safety level of the developed system.

As the first step of risk management, risk identification is inevitable to understand the degree of work safety. However, the safety requirements can be divided in necessary factors and additional factors. Thus, we propose a safety requirements assessment model using Kano model derived from Herzberg's two-factor theory, classifying safety requirements into ideal elements and must-be elements. The Kano model is usually applied to evaluate customer satisfaction divided into three major requirements in the fields of product development and marketing: attractive, must-be, and one-dimensional requirements. Among them, attractive requirement and must-be requirement are matched with ideal element and must-be element for safety requirement classification, respectively. The ideal element is defined as preventive safety elements to make systems more safe and the must-be element is referred to as fatal elements to be essentially eliminated in systems. Also, coefficients of safety measurement and safety prevention are developed to classify different class of safety requirements. The positioning map is finally visualized in terms of both coefficients to compare the different features. Consequently, the proposed model enables safety managers to make a decision between safety measurement and prevention.

소프트웨어 개발에 투자되는 자원은 한정되어 있으므로 요구사항들을 우선순위화하여 중요한 요구사항부터 충족시켜야 한다. 기존 요구사항 우선순위화 기법들은 인간의 수동화된 판단에 의존하므로 요구사항의 수가 많은 경우에는 적용하기가 힘든 확장성 문제와 이해관계자 개개인의 편향된 가치판단에 노출되는 편향성 문제를 가지고 있다. 이 문제들을 해결하고자 본 논문은 요구사항 도출 단계에서 얻어지는 이해관계자 요구 산출물과 텍스트의 의미적 주제를 추리하는 토픽 모델링 기법을 이용한 자동 요구사항 우선순위화 기법, ToMSN(Topic Modeling Stakeholder Needs for requirements prioritization)을 제안한다. 이 기법을 사용자 30,000명 규모의 실제 소프트웨어 요구사항 데이터로 평가한 결과, 인간의 개입이 필요 없는 자동화 과정으로 확장성과 편향성 문제를 해결함과 더불어 우선순위화 정확도 또한 기존 수동화 기법들과 유사함을 확인할 수 있었다.

소프트웨어의 성공적인 개발을 위해서는 체계적이고 명확한 요구분석이 이루어져야 한다. UML에서는 유스케이스 모델링을 통해 사용자 또는 고객의 요구사항을 파악하고 업무 시스템의 범위를 결정하는 방법을 제공하고 있다. 본 논문에서는 효율적이며 정확한 유스케이스 모델링을 위한 연구의 일환으로, 요구사항 기술서로부터 정형화된 규칙을 적용해 가면서 단계적으로 유스케이스 다이어그램을 추출하는 기법을 제시하였다. 요구사항 기술서 관련규칙( $R_{A}$; Rules for Requirements Specification)을 적용하여 요구사항 기술서를 변경하고, 변경된 요구사항 기술서에 액터 추출 규칙( $R_{A}$ ; Rules for Actors), 유스케이스 추출 규칙( $R_{U}$ ; Rules for Use Cases), 관계 추출 규칙( $R_{R}$ ; Rules for Relationships)을 각각 적용하여 액터, 유스케이스, 관계를 추출하여 최종적으로 유스케이스 다이어그램(Use Case diagram)을 작성하게 된다. 본 논문에서 제시한 규칙을 인사관리 요구사항 기술서에 적용해 본 결과, 정형화된 규칙이 없이 서술적인 몇몇 조언을 바탕으로 유스케이스 다이어그램을 추출해야하는 기존의 어려움을 줄일 수 있는 효과를 확인하였다.확인하였다.
