The utility and the nuclear research institutes in korea have conducted research for improving inefficient requirements in technical specifications using the results of probability risk assessments and informations with risk. However, the guidance for reviewing the improved technical specifications has not been developed. The objective of this study is to develop a decision-making framework for investigating and reviewing the technical documents associated with the to changes of technical specification This study has developed a decision-making framework for reviewing the improvements of the RI-TS(Risk-Informed Technical Specifications). This work may contribute to enhancing both the safety and the efficiency of nuclear power plants by changing Technical Specifications proposed by the utility.

This is to provide basic information and technical data, supported by literature search, for use in designing and /or evaluating ventilation systems for broiler shelters. At first, the general design information including weather data, building requirements, ventilation requirements, and supplemental heating and cooling, was presented. Then, environment requirements for broilers, which are for temperature, humidity, air movement, radiant heat, were described and the optimal ventilation systems for broiler were developed.

Purpose: This study aimed to determine the core competencies for 119 emergency medical technicians (EMTs) and to provide evidence for the development and utilization of 119 EMTs, education and training programs. Methods: Data were collected with a questionnaire that consisted of items on the general characteristics of the subjects (8 items) and importance and satisfaction levels for 10 competencies, including 34 items on subfactors. The Borich Needs Assessment Model was used in designing the questionnaire. A locus for focus model was used to derive the top priority competencies for the improvement of core competency in the profession. Data were analyzed with by SPSS ver.21 (IBM, Armonk, NY, USA). Results: The core competencies for 119 EMTs were derived from technical competency, information competency, communication competency, problem-solving competency, self-development competency and interpersonal competency. In addition, among the sub-factors of these competencies, 16 abilities (including leadership), ability to apply technical knowledge, technical comprehension, conflict management ability, ability to create documents, problem handling ability, ability to think, technical selection ability, and computer literacy were included in the priority category. Conclusion: This study derived and presented the core competencies for 119 EMTs to enable them to meet the modern day requirements of their roles, which may contribute to enhancing their professionalism.

Most of systems engineers make a traceability matrix and attach it to their technical documents as a result of systems engineering activities. I have been working in the field of systems engineering for many years and have been watching traceability matrices created by systems engineers or developers from various companies. I have been thinking that some of them are not suitable in terms of purposes of traceability matrix. In this paper, I would like to suggest a right template for the traceability matrix in conformance to traceability purposes. The key is that traceability matrix should be created from higher level of requirements to current level of requirements.

Modern naval ships are large complex systems with the number of requirements ranges from thousands to tens of thousands. To build a quality ship, the satisfaction of the requirements should be traced. In most shipbuilding projects it is almost impossible to manage all the requirements without a proper CASE (computer aided systems engineering) tool. And for effective management of the shipbuilding project, the integrated database for technical data is very important. This paper describes how the requirements are managed, and the integrated database is built in the naval shipbuilding industry in Korea.

In order to implement the smart home environment, we need an intelligence service platform that learns the user's life style and behavioral patterns, and recommends appropriate services to the user. The intelligence service platform should embed a couple of effective and efficient data mining algorithms for learning from the data that is gathered from the smart home environment. In this study, we evaluate the suitability of data mining algorithms for smart home intelligent service platforms. In order to do this, we first develop an intelligent service scenario for smart home environment, which is utilized to derive functional and technical requirements for data mining algorithms that is equipped in the smart home intelligent service platform. We then evaluate the suitability of several data mining algorithms by employing the analytic hierarchy process technique. Applying the analytical hierarchy process technique, we first score the importance of functional and technical requirements through a hierarchical structure of pairwise comparisons made by experts, and then assess the suitability of data mining algorithms for each functional and technical requirements. There are several studies for smart home service and platforms, but most of the study have focused on a certain smart home service or a certain service platform implementation. In this study, we focus on the general requirements and suitability of data mining algorithms themselves that are equipped in smart home intelligent service platform. As a result, we provide a general guideline to choose appropriate data mining techniques when building a smart home intelligent service platform.

The technical requirements to the propellant of rocket engine using chemical energy are developed from the point of its performance, design and the exploration. The propellant, i.e. to get higher energy, to increase the cooling effect, and to be used in safety and comfort should be made. So from these aspect the technical requirements were written by the factors of physical chemistry. And the propellant combination used recently in Launch vehicles is liquid Oxygen and Kerosene, the main characteristics of this Kerosene as a fuel were reviewed. The toxicity and the safety of Kerosene, in specially, require the attention of the users. Also, it would be used in the development of Korean Kerosene by the comparative review of the several Kerosenes in Abroad.

User satisfaction has always been important in the success of software, regardless of whether it is closed and proprietary or open source software (OSS). OSS users are geographically distributed and include technical as well as novice users. However, it is generally believed that if OSS was more usable, its popularity would increase tremendously. Hence, users and their requirements need to be addressed in the priorities of an OSS environment. Online public forums are a major medium of communication for the OSS community. The research model of this work studies the relationship between user requirements in open source software and online public forums. To conduct this research, we used a dataset consisting of 100 open source software projects in different categories. The results show that online forums play a significant role in identifying user requirements and addressing their requests in open source software.

The BIM libraries and technical contents in order to develop common technical standards that reflect the contents for a BIM design support should be based. It is essential to redress the technological burden on design office requirements. The technical contents consisted of Material Information, Standard Details and Cost Information are made by system of standard classification. By connecting BIM libraries with each of information including the contents, it derives the consistent BIM data application through the integrated model. In addition, we look forward to introducing and applying BIM more easily through securing common technical contents which remove the pressure of engineering developments of each individual architectural design office and prevent overlapping investments.
