This study is objected by suggesting rationalization method of management and maintenance cost for railway investment assessment. The estimate of rational benefit and cost are a work of vital importance to decide railway investment as preliminary feasibility investigation is institutionally reinforced since January 2007. In particular, railway management and maintenance cost have to be applied to realistic and detail cost as railway investment assessment guide. For example, types of railway, construction of new line, improvement of conventional line, double tracking, railway electrification. However, railway investment assessment is inconsistency because of estimating the railway management and maintenance cost using existing unrealistic management and maintenance cost. Therefore, this study is performed parametric analysis effecting on the railway management and maintenance cost considered new technique, enhanced facilities and improved standard. Also, it suggests the itemized standard management and maintenance cost. Finally, it will be helped to establish the base of railway investment through the rationalization method of management and maintenance cost.

Purpose: Addressing current status of nursing handoff provides information as to where to change practice for improvement in patient care. The aim of this study was to develop nursing a handoff practice guideline and standardsfor Korean hospitals. Methods: A questionnaire was used to collect data in a cross-sectional survey with 207 head nurses and 697 nurses working in general hospitals. Results: The practice guideline consisted of 2 items on purpose of handoff, 5 items on policy, 3 on environment, 5 on process, 7 on content, 3 on evaluation, and 1 on the function of education, for a total 26 of items. Standard instruction was developed related to Patients, Assessment, Situation, Safety concerns, Background, Actions, and Recommendations. Conclusion: The findings of this study indicate that the guideline can be applied in real nursing practice to improve the effectiveness of handoff procedures. It can be used to guide nurses to follow the standardized content, which presents patient details clearly. The guideline provides consistency and structure for the information that is handed over.

The main objective of this work is to propose a reliable routine standard operation procedures (SOP) for structural health monitoring and diagnosis of nuclear power plants (NPPs). At present, NPPs have monitoring systems that can be used to obtain the quantitative health record of containment (CTMT) buildings through system identification technology. However, because the measurement signals are often interfered with by noise, the identification results may introduce erroneous conclusions if the measured data is directly adopted. Therefore, this paper recommends the SOP for signal screening and the required identification procedures to identify the dynamic characteristics of the CTMT of NPPs. In the SOP, three recommend methods are proposed including the Recursive Least Squares (RLS), the Observer Kalman Filter Identification/Eigensystem Realization Algorithm (OKID/ERA), and the Frequency Response Function (FRF). The identification results can be verified by comparing the results of different methods. Finally, a preliminary CTMT healthy record can be established based on the limited number of earthquake records. It can be served as the quantitative reference to expedite the restart procedure. If the fundamental frequency of the CTMT drops significantly after the Operating Basis Earthquake and Safe Shutdown Earthquake (OBE/SSE), it means that the restart actions suggested by the regulatory guide should be taken in place immediately.

This Study tried to approach with a new Point of view about Green Design that had been studied on just Aesthetics and Function and it focused on creating a pleasant environment In the Interiors combing with Horticultural therapy as advanced study in Green Design. This study is barred on understanding that nature, human and space should continue to coexist through realizing relationship between nature and human and overcoming denaturalization and dehumanization and have an opportunity to know what a pleasant space for human is. Although pleasant space can be made by many different methods, this study start from the thought that a space with plants is the best to satisfy human's basic emotion. The method of study is through research and analysis with many kinds of references and examples, and then the results were used to make design guide which introduces Green Amenity Space in residential space. The pleasant space that human pursuits should be the human-centered space as well as the space giving them mental and physical satisfaction beyond space with just function and beauty. Therefore Green Amenity Space is the best space with which human is familiar.

Children exposed to potentially traumatic events are at risk of developing posttraumatic stress disorder (PTSD). However, the subsequent developmental course of posttraumatic stress symptoms appears to vary considerably. In this regard, some PTSD symptoms resolve without significant interventions, while for many children and adolescents, they persist until the patient receives appropriate treatment specifically designed to address PTSD and other trauma related symptoms. Evidence-based psychotherapies represent the standard of care for children with PTSD and, while psychopharmacologic interventions are utilized for many youth with posttraumatic stress symptoms and PTSD, there is little data available to guide the use of these medications in this population. However, given the structural challenges involved in disseminating and delivering evidence-based psychotherapies in all settings, prescribing clinicians should be aware of the medications whose use in children with pediatric PTSD has been studied. Herein, we review the PTSD assessment modalities, as well as the use of pharmacologic interventions in PTSD, including antiadrenergic agents, selective serotonin reuptake inhibitors and other medications.

The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

In clinical use, coronary stents keep coronary arteries open after expansion with a balloon catheter and prevent the expanded artery from collapsing. Coronary stents are positioned in artery by catheter with a balloon along a guide wire to the lesion site. Flexibility is one of important ability for delivery. In this paper, Palmaz-Schatz stent and Tenax complete stent were selected because these are the most representative of tubular stents. Finite element analyses for the stent system were performed using ABAQUS/Standard code. The present study estimated the flexibility of coronary stents due to loading directions. Moreover the present paper suggests a numerical method to test the flexibility of stents. In conclusion this paper shows how the finite element analysis can be effectively organized in the stent development.
