Objectives: For diagnosis and evaluation, evaluation tools are needed. Various tools can be used to diagnose and evaluate mental disorders. Among them, psychological tests are widely used. For Korean Standard Classification of Diseases (KCD) diagnosis, psychological tests are also required. Currently developed critical pathway (CP) presented tools for diagnosis and evaluation of mental disorders. The CP suggests the use of tools based on the Clinical Practice Guideline (CPG). Therefore, CPG-based tools should be able to be used in the clinical scene of Korean Medicine for diagnosing and evaluating mental disorders according to CP. Methods: Tools suggested by CPs are summarized. The degree of utilization of tools in CPGs is also summarized. A review was conducted by Korean Medicine neuropsychiatrist experts on tools and user's usage plan. Results: As a result, developed CPs suggested using 19 tools for anxiety disorder, 13 tools for insomnia), 12 tools for Hwabyeong, and 9 tools for dementia. In CPG, 48, 34, 44, and 44 tools were used for anxiety disorder, insomnia, Hwabyeong, and dementia, respectively. Among tools presented in CP, HAM-A, HAM-D, CGI, SAS, and TESS for anxiety disorder, CPG, ISI, and PSQI for insomnia disorder, CPG, STAI, and STAXI for Hwabyeong were frequently used in CPG. For dementia CPG, MoCA, MMSE, HDS, ADL, and ADAS-cog were frequently used. Among them, MoCA, ADL, and ADAS-cog were suggested tools in CP. Conclusions: As a result of analyzing tools suggested and used in the developed CPs and CPGs, it was verified that various tools were used in each study. Most of them were symptom and behavioral evaluation scales. Therefore, symptoms and behavior evaluation scales used more frequently should be able to be used in the clinical scene of Korean Medicine.

Evaluation of the mechanical properties of Bi-2223/Ag HTS tapes was carried out by the tension and bending tests. Most of the Bi-2223/Ag tapes retained critical current up to 10 kgf/mm$_2$ axial tension stress, and 0.2% tension strain at room temperature. Applied tension strain exceeding 0.3% in superconducting tapes at 77 K leaded to rapid degradation of the critical current. It was observed that the more filaments, the better axial tension property at 77 K, self-field The influence of bending strain on critical current degradation was revealed to be less sensitive for Bi-2223/Ag HTS tapes with a more number of filaments and higher silver ratio.

This article aimed to summarize the impact and burden of pediatric postintensive care syndrome (PICS-p) in the physical, mental, cognitive, and social health domains after a review of the current pediatric literature in MEDLINE and PubMed. We also aimed to elucidate the limitations of the current evaluation tools used in limited-resource settings. PICS-p can impact a child's life for decades. Most validated tools are time-consuming, require qualifications, and expertise, are often limited to older children, and can evaluate only one domain. A novel, simple, and comprehensive surveillance tool can aid healthcare providers in the early detection and intervention of PICS-p. Further studies should validate and refine the parameters that will enhance the outcomes of pediatric intensive care unit survivors.

원자력발전소의 발전소보호계통과 같은 안전필수 시스템은 예상 가능한 사고로부터 인간과 자연을 보호하기 위한 중요 기능을 수행하는 시스템으로써, 어떠한 조건 하에서도 고유의 안전기능을 안정적으로 수행할 수 있도록 설계되어야 한다. 원자력발전소의 안전필수 기능을 수행하는 계측제어시스템에 적용되는 최신의 컴퓨터에는 다양한 하부기기를 감시 및 제어하고, 응용 프로그램을 실행시키기 위한 실시간 운영체제가 탑재되어 있으며, 이러한 실시간 운영체제는 가장 엄격한 소프트웨어 품질이 요구된다. 또한, 예상 가능한 조건에서도 안전필수 시스템의 기능이 적절히 수행될 수 있도록 설계, 분석 및 평가되어야 한다. 그러나 지금까지 국내 원자력발전소 안전필수 시스템에는, 원자력 기준과 품질등급에 따라 개발된 제품이 아닌 상용제품의 실시간 운영체제를 정성적 측면에서 승인(Commercial Grade Item Dedication)하는 방식으로 적용되어 왔다. 이로 인해 실시간 운영체제가 안전필수 기능을 수행하는 데 적합한지를 평가하는 상세 방법론과 경험이 매우 부족한 것으로 파악되고 있다. 특히, 안전필수 시스템에 적용함을 목적으로 신규 개발되는 실시간 운영체제의 경우, 안전성을 평가하기 위한 적절한 방법을 도출하기에 어려움이 있는 것으로 파악되고 있다. 본 논문에서는 원전의 안전필수 기능을 수행하는 실시간 운영체제의 설계요구사항을 기반으로, 안전필수 실시간 운영체제에 대한 안전성 분석 및 평가 사례를 제시하고자 한다. 본 논문에서 제시한 상세 안전성 평가의 방법과 사례는 향후 타 산업분야에서의 안전필수 실시간 운영체제 개발 및 안전성 평가에 활용될 수 있을 것으로 기대된다.

Cost containment has become high political issues since financial crisis of the Korean Health Insurance fund in 2000. Korean Government has developed and implemented several measures to reduce the pharmaceutical expenditures. Pharmaceutical economic evaluation can be a tool in decision to allocate scare resource efficiently. In order to increase the quality of economic evaluation for pharmaceuticals, the Korean Health Insurance Review Agency(HIRA) is considering the development of a guideline for economic evaluation. It mandates that pharmaceutical companies could submit the result of an economic evaluation when demanding reimbursement of new pharmaceutical drugs. The purpose of this study is to provide a critical review of the economic evaluations of health care technologies published in the Korean context whether they have been performed according to current guidelines and therefore whether their results are directly useful for decision making. We found there exist important problems and deviation from, good practice' both in the general features of the studies, like the study design and perspective, and in terms of cost measurement and valuation. There are needs to develop clear guidelines and to educate and train researchers in performing economic evaluations.

Nondestructive evaluation for mechanical degradation of ultrasuper-critical (USC) heat-resistance steel, which is attractive to the next generation of power plants is studied by magnetic reversible permeability. The interrelationship between reversible permeability and high-temperature mechanical degradation has been investigated by precise measurement of permeability nondestructively. Also, the effects of microstructural variation on reversible permeability are discussed. Isothermal aging was observed to coarsen the tempered carbides ($Cr_{23}C_6$), generated the intermetallic phases ($Fe_2W$), and grow rapidly during aging. The dislocation density also decreases steeply within lath interior. The peak to peak interval (PPI) of reversible permeability profile decreased drastically during the initial 500 h aging period, and was thereafter observed to decrease only slightly. The variation in PPI is closely related to the decrease in the number of pinning sites and the degradation in tensile strength.

Australia has joined many governments to adopt public-private partnership (PPP) as a major strategy for procuring infrastructure for decades. However, failures have occurred although the market has been considered to be a mature and sophisticated one. Failures have typically been traced back to inappropriate economic evaluation and a lack of value-for-money. In particular, a literature review has identified that there was no holistic consideration on the evaluation of procurement transactions of PPP projects. The transaction costs of PPPs were not handled properly. In this paper, theories of transaction cost economics are proposed for the purpose of such a holistic institutional economic evaluation. These theories are analysed in order to identify potential critical success factors for a strategic infrastructure procurement framework. The potential critical success factors are identified and grouped into a number of categories that match the theories of transaction cost economics. These categories include (1) Asset Specificity, (2) Organizational Capability, (3) Transaction Frequency, (4) Behavioural Uncertainty, and (5) Environmental Uncertainty. These potential critical success factors may be subject to an empirical test in the future. The proposed framework will offer decision makers with an insight into project life cycle economic outcomes needed to successfully deliver PPPs.

The purpose of this paper is to examine the differences in the critical success factors for ERP adoption suggested by the system managers and the ERP consultants. The survey results indicated the following findings. First, there was no significant difference in the relative importance of the critical success factors between the system managers and the ERP consultants. Both groups agree that 'top manager's concern and support' is the most critical factor and that 'user involvement' is the second. However, the system managers tend to think 'training and education of end users' and 'cooperations among the project participants' more important than the consultants do. Second, both groups agree that the most important ERP contribution should be 'improvements in the business processes.' They also agree that the least important aspect is 'ERP's contribution to the individual's productivity.' In overall, the ordered lists of ERP evaluation criteria according to their importances were of no significant difference between the groups. Third the two groups showed differences when they were asked to evaluate the importance of the critical success factors for each of the ERP evaluation criterion. In general, the system managers tend to put more emphasis on 'training and education of end users' and 'adaptation of end users to the changed processes,' whereas the consultants tend to emphasize more on 'top managers' interest and supports' and 'project manager's capabilities and performance.' The differences in the critical success factors presented by the two groups indicated that more efforts need to be devoted to understanding other participant's interests and concerns in an ERP project team. Better coordinations based on the mutual understandings could improve the chance of achieving a success in adopting ERP packages.
