Purpose. To determine and compare the perception among nurses and doctors of the roles and tasks of critical care advanced practice nurses (APNs) in order to establish standardized and formally agreed role criteria for such critical care APNs. Method. This study measured and analyzed the necessity of each of the roles and tasks of critical care APNs, as perceived by nurses and doctors, through a survey of 121 participants: 71 nurses in 7 intensive care units (ICUs) at a general hospital in Seoul, and 50 doctors who used ICUs. Data collection utilized a questionnaire of 128 questions in the following fields: direct practice (79), leadership and change agent (17), consultation and collaboration (15), education and counseling (11), and research (6). Results. Both the nurses' and the doctors' groups confirmed the necessity of critical care APNs, with doctors who frequently used ICUs indicating a particularly strong need. As for the priority of each role of critical care APNs, the nurses considered direct practice to be the most critical, followed by education and counseling, research, consultation and collaboration, and leadership and change agent. The doctors also considered direct practice to be the most critical, followed by education and counseling, consultation and collaboration, research, and leadership and change agent. There was a statistically significant difference between how the two groups regarded all the roles, except for the consultation and collaboration roles. As for the necessity of each role of critical care APNs, the nurses considered research to be the most necessary, followed by education and counseling, consultation and collaboration, leadership and change agent, and direct practice. The doctors, on the other hand, considered education and counseling to be the most necessary, followed by research, consultation and collaboration, leadership and change agent, and direct practice. The responses of the two groups to all the roles, except for education and counseling roles, were significantly different. Conclusion. Nurses and doctors have different perceptions of the roles and tasks of critical care APNs. Thus, it is necessary for the combined nursing and medical fields to reach an official agreement on a set of criteria to standardize for the roles and tasks of critical care APNs.

The main object of this study was to clarify the concept, scheme, an dimensions of the clothing evaluatie criteria, and to organize its theoretical framework accordingly. The research was carried out in tow ways. The first research was investigated by the critical evaluation of the existing literature, while the other research was investigated by an empirical survey study. The questionnaire was developed for the empirical study. The questionnaire was administered to 640 housewives living in Seoul area during the fall of 1988. Social wear was selected according to the defined times, place, and occasion. As a result of the literature study, the first research problem, the clothing evaluative criteria was loud to exist at three different level - benefit level, element level, and intemediate level -. The colthing evaluative criteria at the benefit le·eel were loud to include four different dimensions-fashionbility, status symbolism, practicality, and economy. The validity of the benefit dimensions was established by the empirical confirmation utilizing factor analysis technique.

One of the main concerns of railway system is to secure safety. Nowadays digital technology has been rapidly applied to safety critical system. The digital system performs more varying and highly complex functions efficiently compared to the existing analog system because software can be flexibly designed and implemented. The flexible design makes it difficult to predict the software failures. For this reason, the safety criteria are suggested to secure the software safety for the field of railway system. Following them, the railway software have to be examined whether it is properly developed according to the safety criteria and certification process. Because the articles suggested in safety criteria are written in legal term, it is difficult to apply the criteria to develop railway software. This paper suggests and discusses a development and assessment procedure to solve these issues for railway software with more detail description.

The purpose of this study is to determine the optimal gas turbine system for special purpose ships. First we generate critical evaluation criteria an construct their hierarchical structure. The criteria consist of qualitative ones as well as the economic factor. Then AHP is applied to solve the decision making problem AHP gibes good results different from those only by the economic evaluation methods. And during the analysis, the procedure produces many useful informations to the decision making. The results shows that AHP is an appropriate method for these kinds of problems such as the system selection.

In the manuscript, we concern with the existence of solutions of boundary value problems for fourth order nonlinear discrete systems. Some criteria for the existence of at least one nontrivial solution of the problem are obtained. The proof is mainly based upon the variational method and critical point theory. An example is presented to illustrate the main result.

Critical thinking ability based on a sound sense of logic is essential for analyzing a given engineering design problem and assessing it to arrive at the most plausible conclusion. Engineering design classes require students to organize their engineering design experiences through reports, and engineering design reports require detailed specifications of their tasks at each stage. Given the nature of these curriculums, design classes provide writing courses focusing on science and engineering within specialized fields, but there still lies many obstacles for communication education that embraces both general education and major subjects. This study proposes a specified step-by-step writing model for engineering design reports that encompasses critical thinking for the objective of systemizing design experiences from engineering design report writing. For the purpose of the study, the concepts and relationship between critical thinking and creative problem solving have been examined, followed by a proposal of application methods for critical thinking criteria and elements from a case example on engineering design. Furthermore, the study proposes a critical thinking-based assessment rubric for logical decision making at each stage of engineering design as well as a resulting model for engineering design report writing.

In this study, the effective technology readiness assessment (TRA) method for system development project is suggested. We analyze the domestic and foreign TRA practice and derive the new idea to resolve the problems found from the analysis. Domestic and foreign organizations develop and use checklist for the precise TRA, but the checklist has some problems in type of questions and analysis of assessment. TRA method using the original TRL definition or the checklist should be selected depending on the project characteristic. Questions of the checklist should be classified into critical or non-critical according to their importance. Finally, Test and evaluation master plan (TEMP) in system engineering process can provide an obvious criteria to assess technology readiness level (TRL) of critical technology elements (CTE) composing the system.

The requirement of ultra high reliability of the safety critical software can not be demonstrated by testing alone. The specification based on formal method is recommended for safety system software. But there exist various kinds of formal methods, and this variety of formal method is recognized as an obstacle to the wide use of formal method. In this paper six different formal method have been applied to the same part of the functional requirements that is calculation algorithm intensive. The specification results were compared against the criteria that is derived from the characteristics that good software requirements specifications should have and regulatory body recommends to have. The application experience shows that the critical characteristics should be defined first, then appropriate method has to be selected. In our case, the Software Cost Reduction method was recommended for internal condition or calculation algorithm checking, and statechart method is recommended for the external behavioral description.
