In a large complex system, maintenance priorities for the failed components are important to maintain the sys-tern reliability at required level. Commonly used methods of determining maintenance priorities are based onranking the failed components by using reliability importance measures such as Birnbaum reliability importance,risk achievement worth and F-V importance, etc. In the preceding works, maintenance priorities for the failedcomponents are determined by using such existing measures, In this study, a new method of determining main-tenance priorities, which utilizes the joint reliability importance is proposed. By investigating the sign of thejoint reliability importance, maintenance priorities obtained by the existing methods are adjusted to yield new re-vised priorities. The revised maintenance priorities are shown to be more effective than the existing ones fromthe standpoint of the speed of system recovery, Effectiveness of the proposed method is illustrated by numericalexamples.

This research focused on the priotity decision for establishment sriteria on the effects which environmental sculptures in urban area. The analysis performed in this study used the AHP(Analytic Hierarchy Process) that is recognized as a useful decision-making tool to select and evaluate alternatives through pairwise comparison in the context of hierarchical decision structure. The results obtained from the analysis drawn by collecting the professional opinions of 5 experts for environmental sculptures are as follows: 1. The orders of establish criteria priorities on environmental sculptures were harmony of environment> symbol> public> function. The harmony of environment was the most important priority because it showed the highest weight of criteria. 2. The alternative priorities of environmental sculptures were the meaning of work>setting place> social contribution> physical quality .The meaning of work showed the highest change in the weight of alternative. 3.The sensitivity analysis of environmental sculptures demonstrated that the rate of change in the alternative priorities of the public was stabilized although the criteria importance varied, while the harmony of environment, the symbol intimated and function of priorities has their rates of weight changed if the criteria priorities were high.

In Linux, real-time tasks are supported by separating real-time task priorities from non-real-time task priorities. However, this separation of priority ranges may not be effective when real-time tasks make the system calls that are taken care of by the kernel threads. Thus, Linux is considered a soft real-time system. Moreover, kernel threads are configured to have static priorities for throughputs. The static assignment of priorities to kernel threads causes trouble for real-time tasks when real-time tasks require kernel threads to be invoked to handle the system calls because kernel threads do not discriminate between real-time and non-real-time tasks. We present a dynamic kernel thread scheduling mechanism with weighted average priority inheritance protocol (PIP), a variation of the PIP. The scheduling algorithm assigns proper priorities to kernel threads at runtime by monitoring the activities of user-level real-time tasks. Experimental results show that the algorithms can greatly improve the unexpected execution latency of real-time tasks.

Purpose : Life-threatening illnesses represent a crisis for individual patients and their families. Little has been made to understand the priorities or perspectives in developing a care plan. This results in poor outcomes, and patients and families return home without being satisfied with the care provided. This study aimed to address nurses' and families' care priorities on patient and family-centered care principles and compare those priorities. Methods : A quantitative comparative descriptive research was conducted. The data were part of a study that was carried out to elicit and compare nurses' and families' perceptions of complying with patient and family-centered care (PFCC) principles in intensive care units (ICU) in Ghana. The respondents were ICU nurses (n=123) and family members of hospitalized patients in the ICU (n=111). The tool for the study was a "modernized version of a hospital self-assessment inventory on PFCC," and data analyses were performed using SPSS version 20.0. Results : Nurses and families differed significantly in their priorities of care based on the principles of PFCC. The means and p-values were significantly different for the definition, pattern of care and access to information/education, and the overall total scores of the patient and family-centered care principles (PFCCP) Conclusion : To render care that aligns with the care priority of families and patients in the ICU, nurses must plan care in consultation with their families.

Crop-animal systems which form the backbone of agriculture in the tropics are discussed with reference to their characteristics, economic importance of animals, genesis and types of crop-animal systems, relevance and potential importance, and priorities for research and development. These production systems are found across all agroecological zones: rain-fed temperate and highland systems, semi-arid and arid tropics, and sub-humid and humid tropics: the last four are priority areas in Asia. The potential importance of these systems in Asia is reflected in their advantages, synergism and complimentarity, economic benefits and contribution to sustainability. Illustrative case studies are cited which are appropriate to the two broad types of mixed farming systems: systems combining animals and annual cropping, and systems combining animals with perennial cropping with reference to Indonesia, Philippines, Malaysia, Sri Lanka, China and Nigeria. Priorities for research and development should address more complete use of the animal genetic resources, intensive utilisation of the feed resources, development-oriented utilisation of research results, minimizing animal diseases, and implementation of appropriate institutional and policy issues.

본 논문은 항공화물운송서비스 부문의 서비스 이용자와 제공자와 사이의 서비스 품질 중요도의 차이에 대한 연구이다. 즉, 조사된 서비스 수준 결정요인을 중심으로 국제항공물류서비스의 제공자가 지각하고 있는 요소별 중요도와 제공된 서비스에 대해 이용자의 중요도의 차이를 연구하였다. 또한 서비스 제공자는 국적항공사와 외국적 항공사와 구분하여 그 차이를 살펴보았다. 연구에서는 시비스 항목을 공급능력(H/W), 시비스 신뢰성, 운임경쟁력 및 운영능력(S/W)으로 구분하였으며, 각 항목에는 다시 3개에서 6개의 서비스 요소를 총 18개로 세분하였다. 서버스 항목의 중요도 및 인지도에 있어서 서비스 제공자와 이용자간의 중요도에서는 차이가 없었다. 항목별로 보다 세분화된 서비스요소에서는 총 18개 서비스 요소 중 단 3개의 요소에서만 중요도 차이가 있는 것으로 인식 하였다. 그러나 서비스 제공자를 국적항공사와 외국적항공사로 구분을 한 경우에는 7개의 구성요소에서 서비스 제공자(국적항공사, 이ㅗ국적항공사)와 이용자간의 중요도에 관한 인식의 차이를 보이고 있다. 특히 국적항공사는 화물사고처리능력에 가장 큰 중요도를 두고 있는데 반해 외국적항공사는 기본요율체계에 높은 비중을 두었고 차이를 나타냈다. 이러한 결과는 서비스 품질의 중요도에 대한 인식의 차이를 분석하기 위해서는 국적항공사와 외국적항공사 간에 뚜렷한 차이가 존재하므로 서비스 제공자가 하나의 그룹으로 총체적으로 분석되어서는 안 됨을 의미한다.

In this paper we suggested a performance evaluation model for future weapon systems. Weapon Performance Index(WPI) model transform the characteristics of alternatives as indices. We can easily obtain WPIs of alternatives with the model. The highest WPI recommended as the best solution. The performance elements in hierachy for future weapon systems are determined by systems engineering procedure. Priorities in hierachy can be determined through survey of experts engineering procedure. Priorities in hierachy can be determined through survey of experts and statistical analysis. Utility function is formulated as a probability model and utility score is predicted on the basis of historical data about the same category of weapon systems in the world. WPI is calculate from sum of product of priorities and utility scores. The model can be applied to trade-off analysis, cost and effectiveness analysis, war game model.

The objective of this study is to propose a new procedure to synthesize the multi-experts priorities in AHP. If multi-experts with different expertise are involved in a AHP decision, we need some way to aggregate their opinions. AHP model used to do numerical aggregation by taking only the geometric mean or the weighting geometric mean in past. To aggregate the multi-experts priorities, In this paper. we suggest a way which Decision Maker can exclude outlier matrix from group using the concept of the Compatibility and we Introduce Delphi method to use Compatibility in AHP. A numerical example is shown to illustrate the procedure.

The rapid increase in PET devices and its utilization in Korea necessitates relevant health insurance policies based on scientific evidence, including economic evaluation of PET in clinical conditions. However, there is very little amount of evidence regarding PET, and the first step would be to establish research priorities to give a momentum for research and assure efficient use of research capacities. To this end, we conducted a two-round Delphi study, which produced stable consensus on about top 10 oncology indications for research, which included lymphoma staging, colorectal cancer recurrence/restaging, lung cancer staging, and other conditions. The results were largely consistent with current U.S. Medicare reimbursement indications and are expected to lead to relevant researches and evidence-based health policies on PET reimbursement and regulation.
