Traditional acceptance sampling plans have focused on the proportion of nonconforming items as an attribute criterion for quality. In today's modern quality management under high quality production environments, the reduction of the deviation from a target value in a quality characteristic has become the most important purpose. In consequence, various inspection plans for the purpose of reducing the deviation from the target value in the quality characteristic have been investigated. In this case, a concept of the quality loss evaluated by the deviation from the target value has been accepted as the variable evaluation criterion of quality. Further, some quality measures based on the quality loss have been devised; e.g. the process loss and the process capability index. Then, as one of inspection plans based on the quality loss, the rigorous design procedure for the variable sampling plan having desired operating characteristics (VS-OC plan) indexed by the quality loss has been proposed by Yen and Chang in 2009. By the way, since the estimator of the quality loss obeys the non-central chi-square distribution, the rigorous design procedure for the VS-OC plan indexed by the quality loss is complicated. In particular, the rigorous design procedure for the VS-OC plan requires a large number of the repetitive and complicated numerical calculation about the non-central chi-square distribution. On the other hand, an approximate design procedure for the VS-OC plan has been proposed before the proposal of the above rigorous design procedure. The approximate design procedure for the VS-OC plan has been constructed by combining Patnaik approximation relating the non-central chi-square distribution to the central chi-square distribution and Wilson-Hilferty approximation relating the central chi-square distribution to the standard normal distribution. Then, the approximate design procedure has been devised as a convenient procedure without complicated and repetitive numerical calculations. In this study, through some comparisons between the rigorous and approximate design procedures, the applicability of the approximate design procedure has been confirmed.

Purpose: This study was conducted to update nursing practice guidelines for intravenous infusion published in 2017. Methods: The guideline update process was carried out using 22 steps developed by NICE and SIGN. It was agreed to update domains related to central venous infusion therapy. Contents related to peripheral infusion would be updated later. Results: Updated guidelines for central venous infusion therapy consisted of 6 domains and 195 recommendations. The number of recommendations by domain was 11 for general instruction, 14 for central vascular access devices (CVAD) and add-on devices, 13 for nursing management before insertion of CVAD, 30 for management during insertion of CVAD, 51 for management after insertion of CVAD, and 76 for complications. A grade was 29 (14.9%), B grade was 87 (44.6%), and C grade was 79 (40.5%) in the strength of recommendations. A total of 37 (19.0%) recommendations were newly developed and 23 (12.3%) previous recommendations have been modified. The newly developed recommendations were mainly related to the infection control methods. Conclusion: The updated guideline is focused on safe maintenance of central venous infusion therapy. Through this guideline, it is hoped to minimize the occurrence of complications and improve the standardization and efficiency of nursing practice.

The disaster damage can be reduced not only by quick response to its scene, but also by right resource allocation to the right places. The role of information quality on disaster resource has been considered to be an important factor for disaster management. The aim of this research is to investigate and explain the relationship between information quality and performance on disaster resource management. The information quality control for the disaster response operator is central to deliver right information to right people among different government levels such as local, state, and federal government.

In recent years, more and more researches have been focusing on trust management of vehicle ad-hoc networks (VANETs) for improving the safety of vehicles. However, in these researches, little attention has been paid to the location privacy due to the natural conflict between trust and anonymity, which is the basic protection of privacy. Although traffic safety remains the most crucial issue in VANETs, location privacy can be just as important for drivers, and neither can be ignored. In this paper, we propose a beacon-based trust management system, called BTM, that aims to thwart internal attackers from sending false messages in privacy-enhanced VANETs. To evaluate the reliability and performance of the proposed system, we conducted a set of simulations under alteration attacks, bogus message attacks, and message suppression attacks. The simulation results show that the proposed system is highly resilient to adversarial attacks, whether it is under a fixed silent period or random silent period location privacy-enhancement scheme.

One major development in bridge life cycle cost analysis (LCCA) in recent years is to develop deterioration model for bridge components so that the times of repair/replacement throughout a component's life span can be properly determined. Taiwan also developed her own bridge LCCA model in 2003, integrating with the bridge inspection database in the local bridge management system (T-BMS). Under the framework of the local LCCA model, this study employs the reliability method in developing a deterioration model of bridge components. A component deteriorates through time in its reliability, which represents the probability of a component's condition index exceeds a user specified threshold. Model assumptions and rationale are described in the paper. The steps for applying the developed model are explained in detail. Results and findings are reported.

The purpose of this study is to analyze the long-term plans of the central and local governments in order to plan policy and implementing programs. Through this, the governments is find out to reduce administrative burden. Based on the national health plan, evidence and related laws were collected and analyzed. As a quantitative methodology analyzed the contents of related laws in the overall plan. The qualitative methodologies analyzed and categorized the planning status of cities and provinces in the plan and were collated. There are a total of 39 plans for long-term plans by laws. The role of the central and local governments in the public health sector, there are a total of four plans (10.3%) that need to establish long-term and annual plans for the central and local (cities, provinces) government. A total of seven plans (17.9%) were required to establish a plan by the only local government. In terms of the public health sector on the local governments, 20 plans (51.3%) by cities and 12 plans (30.8%) by provinces were established by law. And in the health sector should be established 9 plans (40.9%) by cities and 7 plans (31.8%) by provinces. The plan needs to be reformed and merged between plans so that governments can focus on the program through planning central government policies, reducing local government administration.

This study is a foundational research for establishing the basic plan of the Chungcheongbuk-do Central Library. The research investigates the regional conditions of Chungcheongbuk-do and the status of collections, usage, staff, and programs of public libraries nationwide and major representative libraries. Based on this, a SWOT analysis was conducted to derive the vision, goals, and implementation strategies for establishing the basic plan of the Chungcheongbuk-do Central Library. Based on the research findings, the mission of the Chungcheongbuk-do Central Library is presented as "The library that grows alongside the lives of local residents, intersecting knowledge and culture."
