Purpose: The purpose of this study was to examine the differences in requirement and activity related to workers' health promotion according to business type and enterprise size. Methods: This study is a secondary analysis of data extracted from a survey on the Enterprise Health Promotion Index. For the present analysis, 7,784 companies were selected. Results: Requirements for lifestyle management and activities to prevent musculoskeletal disorders were the highest. The requirement and activity of musculoskeletal disorders and cerebrovascular disease were high in the manufacturing industry. Meanwhile, in the non-manufacturing industry, the requirement and activity of job stress management were high. Small-sized companies had a high requirement to prevent musculoskeletal disorders and cerebrovascular disease. Conclusion: Government support should be strengthened in workers' lifestyle management. Additionally, workers' health promotion in small-sized companies needs to focus on preventing musculoskeletal disorders and cerebrovascular disease.

The current software industry has an emerging issue with natural language-based requirement specifications. However, the accuracy of such requirement analysis remains a concern. It is noted that most errors still occur at the requirement specification stage. Defining and analyzing requirements based on natural language has become necessary. To address this issue, the linguistic theories of Chomsky and Fillmore are applied to the analysis of natural language-based requirements. This involves identifying the semantics of morphemes and nouns. Consequently, a mechanism was proposed for extracting object state designs and automatically generating code templates. Building on this mechanism, I suggest generating natural language-based comic images. Utilizing state diagrams, I apply changes to the states of comic characters (protagonists) and extract variations in their expressions. This introduces a novel approach to comic image generation. I anticipate highly productive comic creation by applying software processes to Cartoon ART.

실제 물리적 공간에 유비쿼터스 서비스를 개발하여 실현하는 작업이 유비쿼터스 지능 공간 구축을 위해 진행 중에 있다. 또한 이와 같은 유비쿼터스 지능 공간 개발은 전 세계적으로 다양한 분야에서 이루어지고 있다. 이러한 유비쿼터스 지능 공간을 개발하기 위한 방법론 중에서 먼저 시나리오를 제작 분석하고 이에 따라 요구분석과 설계를 하기도 하며 역으로 개발에 고려하고 있는 유비쿼터스 기술로 먼저 설계나 요구분석을 실시하고 이후에 시나리오를 통하여 실현 가능성을 보이기도 한다. 그러나 시나리오 제작과 요구분석이 상호 유사한 내용을 공유하고 있음에도 불구하고 별도로 제작하는 과정에서 불일치와 많은 노력이 소모된다. 따라서 본 논문의 목적은 시나리오 제작과 요구분석 문서를 생성하는 시스템을 제안하는 것이다.

클라우드 서비스가 다양해지고 그 수가 급격히 증가하면서 클라우드 서비스 사용자에게 적합한 서비스를 제공하기가 어려워지고 있다. 이러한 문제를 해결하기 위해 서비스 사용자와 제공자 사이에서 클라우드 서비스를 중개해주는 클라우드 서비스 브로커라는 개념이 제시되었다. 클라우드 서비스 브로커의 핵심적인 역할은 사용자의 요구사항에 적합한 서비스를 찾아주는 것이다. 그러나 현재 제시된 클라우드 서비스 브로커 대부분은 클라우드 서비스 전문가의 도움으로 사용자의 요구사항을 분석하는 수동적인 과정이 수행되고 있으며, 체계적으로 기능적, 비기능적 요구사항을 분석하는 과정이 미흡하다. 따라서 유사한 기능을 가지고 있는 클라우드 서비스 중 사용자의 요구사항의 중요도를 분석해서 가장 근접한 서비스의 선택을 지원해줄 수 있는 요구사항 분석 기법이 필요하다. 본 논문은 AHP(Analytic Hierarchy Process)의 쌍대비교법을 응용하여 클라우드 서비스에 대한 사용자의 요구사항을 분석하고 각 서비스의 명세에 따른 점수를 계산하여 그 결과에 따라 클라우드 서비스를 선택하는 방법을 제시한다.

This review is focused on analyzing the limits and shortage of zinc (Zn) for the 2020 Dietary Reference Intakes for Koreans (KDRIs), and provides suggestions for the future establishment of the 2025 KDRIs for Zn. The 2020 KDRIs for Zn have been established to estimate the adequate requirement (EAR), recommended nutrient intakes (RNI), adequate intake (for only 0-5 mon) and tolerable upper intake level (UL). EAR was estimated in 2-stages: the first stage was to construct of the frame of analysis for Zn requirement and the second stage involved a factorial approach by considering the various factors which affect Zn requirement, such as intestinal and urine Zn loss, Zn requirement for growth and development, and Zn absorption rate. For a more precise and accurate establishment of the Zn requirement, we suggest for the following to be considered: 1) considering that Zn is present in minuscule amounts as a trace element in our body, the present values for Zn EAR (as 6-9 mg/d) should be expressed as a decimal point for more accurate DRIs; 2) the frame of analysis for Zn requirement has to be more specifically and should includes the factors which affect Zn requirement; 3) both, the factorial approach and extrapolation method need to be well reviewed and thoroughly understood for establishing precise Zn requirement; 4) currently, human clinical study and balance study (Zn intake, excretion and absorption rate) are limited and more human Zn subject studies are required. All these suggestions are provided to better establish the Zn requirement in the 2025 KDRIs.

As the introduction of wind power is steadily increasing, negative effects of wind power become more important. To operate a power system more reliable, the system operator needs to recognize the maximum required capacity of available generators for a certain period. For recognizing the maximum capacity, this paper proposes a methodology to determine an optimal reserve requirement considering wind power, for the certain period in the mid-term perspective. As wind speed is predicted earlier, the difference of the forecasted and the actual wind speed becomes greater. All possible forecast errors should be considered in determining optimal reserve, and they are represented explicitly by the proposed matrix form in this paper. In addition, impacts of the generator failure are also analyzed using the matrix form. Through three main stages which are the scheduling, contingency and evaluation stages, costs associated with power generation, reserve procurement and the usage, and the reliability cost are calculated. The optimal reserve requirement is determined so as to minimize the sum of these costs based on the cost/reliability analysis. In case study, it is performed to analyze the impact of wind power penetration on the reserve requirement, and how major factors affect it.

This paper describes system technical requirement development process from operational concept using computer-aided Systems Engineering tool(CASysE Tool-CORE). The army tactical missile system-ATACMS's technical requirements are developed by the process as a case-study The scope of the work is context analysis and requirement definition process. The proposed process is as follows. At first, an integrated architecture could be developed from the operational concept. From the integrated architecture a capability needs, which includes KPPs, are generated. And the capability needs expanded according to the Mil-Std-961D format. Lastly, a system technical requirement could be generated automatically from the CASysE Tool-CORE.

The primary goal of the requirement analysis phase during information system development is to identify and document what is really needed, in a form that clearly communicates to the user and to development team members. Presented in this paper is a QFD(Quality Function Deployment)-based requirement analysis method and procedure for developing a large-scale enterprise information system. For the purpose of elicitation of software functional requirements, this paper adopts the method of HOQ(House Of Quality) and proposes a simplified HOQ which is more suitable for the software requirement analysis. As a result of this paper, it suggests desired functionalities for an integrated design &manufacturing information system.

According to the change in diverse tendency of residents, construction companies has developed the brands of apartments with the concepts of LOHAS, well-being, ubiquitous, etc. The purpose of this study was to suggest space requirement and planning for residents characteristics. The questionnaire survey was adopted in this study and 252 cases were used for data analysis. The survey analysis has been made by using of SPSS WIN 12.0. The major findings were as follows; (1) Resident opinion about the direction of each space was investigated into the need of South-facing in master bedroom highly. (2) The residents didn't want to decrease the current size of each space, the space which wanted to increase was livingroom. (3) The significant variables of space requirement and planning for residents characteristics were family life cycle, the age of householder, the occupation of householder, the size of apartment.
