Maritime infrastructure is at high risk for corrosion-related damage over its service life. These assets are routinely subjected to harsh exposures and heavy usage that can degrade ordinary protective measures for reinforced concrete and steel elements. For owners and operators of ports and other maritime facilities, beginning with a strategic corrosion management plan is a proactive approach for maintenance and replacement needs. A corrosion management plan begins with understanding a few key items. First, identify what infrastructure elements are present and should be inventoried. Second, identify what construction materials and corrosion protection measures are already in place. Third, understand the nature and severity of environmental and usage-related exposures and impact on corrosion. Corrosion management plans have been adopted widely over the years by the oil, gas, and process industries for maintenance of various kinds of equipment, piping, and other needs. However, adoption of these techniques and procedures for civil and maritime infrastructure is still in its early stages. This paper presents the common types of techniques, methods, and documents available for inspecting maritime assets, evaluating exposures, and calculating service life of maritime infrastructure.

AbstractWithin the last century, coastal structures for infrastructure applications have traditionally been constructed with timber, structural steel, and/or steel-reinforced/prestressed concrete. Given asset owners’ desires for increased service-life; reduced maintenance, repair and rehabilitation; liability; resilience; and sustainability, it has become clear that traditional construction materials cannot reliably meet these challenges without periodic and costly intervention. Fiber-Reinforced Polymer (FRP) composites have been successfully utilized for durable bridge applications for several decades, demonstrating their ability to provide reduced maintenance costs, extend service life, and significantly increase design durability. This paper explores a representative sample of these applications, related specifically to internal reinforcement for concrete structures in both passive (RC) and pre-tensioned (PC) applications, and contrasts them with the time-dependent effect and cost of corrosion in transportation infrastructure. Recent development of authoritative design guidelines within the US and international engineering communities is summarized and a examples of RC/PC verses FRP-RC/PC presented to show the sustainable (economic and environmental) advantage of composite structures in the coastal environment.

Management Recommendations

Diagnostic accuracy and management recommendations of realtime teledermatology consultations using low-cost telemedicine equipment were evaluated. Patients were seen by a dermatologist over a video-link and a diagnosis and treatment plan were recorded. This was followed by a face-to-face consultation on the same day to confirm the earlier diagnosis and management plan. A total of 351 patients with 427 diagnoses participated. Sixty-seven per cent of the diagnoses made over the video-link agreed with the face-to-face diagnosis. Clinical management plans were recorded for 214 patients with 252 diagnoses. For this cohort, 44 of the patients were seen by the same dermatologist at both consultations, while 56 were seen by a different dermatologist. In 64 of cases the same management plan was recommended at both consultations; a sub-optimum treatment plan was recommended in 8 of cases; and in 9 of cases the video-link management plans were judged to be inappropriate. In 20 of cases the dermatologist was unable to recommend a suitable management plan by video-link. There were significant differences in the ability to recommend an optimum management plan by video-link when a different dermatologist made the reference management plan. The results indicate that a high proportion of dermatological conditions can be successfully managed by realtime teledermatology.

Abstract An analysis of the dynamics of groundwater levels in the Groundwater Dependent Ecosystems (GDEs), which cover a vast part of the middle Vistula River valley in central Poland was carried out. The study area, typical of large river valleys, was investigated by detailed monitoring of groundwater levels. Based on statistical analysis and the geo-statistical modeling of monitoring data for 1999-2013, the range and dynamics of groundwater level fluctuations were determined for the entire interval and for the vegetation periods. The values of retention and infiltration recharge in various periods were compared with average values, indicating intervals of potential groundwater deficiency in GDEs. The amplitude of groundwater fluctuations, retention and infiltration were determined for vegetation periods characterized by the highest water intake by plants and the highest evapotranspiration. Particular attention has been drawn to the analysis of low groundwater levels in the vegetation periods, with water deficiencies potentially threatening the correct functioning of plant communities in GDEs. Moreover, the study has allowed us to indicate areas with insufficient groundwater levels during vegetation periods that may be hazardous to plant communities. The results may be a basis for the elaboration of correct management plans, protection measures and projects, or GDE renaturalization.

ABSTRACT OBJECTIVE To analyze the relationships between victimization, perception of insecurity, and changes in routines. METHODS The 8,170 subjects of both sexes (49.9% women and 50.1% men) aged between 12 and 60 years, selected from a proportional stratified sampling, participated in this study. The measuring instrument was an adaptation of the National Survey on Victimization and Perception of Public Security. Chi-square tests were performed. RESULTS The results show significant differences on victimization and sex regarding perception of insecurity, restrictions on everyday activities, and protection measures. 13.1% of those interviewed claimed to have been victims of a crime in the past 12 months. 52.7% of women considered their municipality as unsafe or very unsafe. In the case of men, this percentage was 58.2%. Female victims reported significant restrictions in everyday activities when compared to non-victims. In relation to men, the percentage of victims with a high restriction of activities was higher in male victims than non-victims. In the group of victimized women, the segment of women who opted for increased measures of protection against crime was larger than expected, while those of non-victims who took less protective measures was lower than expected. These same results were observed in the group of men. CONCLUSIONS The experience of victimization implies a greater perception of insecurity. However, the climate of insecurity is widespread in a large number of citizens. Gender differences in a high-crime environment show the importance of investigating in depth the roles of both genders in the perception of insecurity and changes in routines.

Protected areas are the most frequently used tool for the mitigation of threats to biodiversity. However, without effective management, the creation of new protected areas may be ineffective. In Brazil, protected areas must have both a governing body (consultative or deliberative council) and an official management plan. Here, we analyzed general trends and patterns in the approval of the management plans for Brazilian federal protected areas. We considered all federal protected areas, and compiled data on (i) the year the area was created, (ii) the type of protected area (integral protection vs. sustainable use), (iii) year its management plan was approved, (iv) year in which the management plan was revised after its approval, (v) total area (in hectares), and (vi) the biome in which the area is located. We stablished three groups of protected area: 1) Group A: protected areas created prior to 1979, 2) Group B: protected areas created between 1979 and 1999, and 3) Group C: protected areas created between 2000 to the present time. Finally, we tested whether time for the approval of the management plan suffered a simultaneous effect of the type of biome and type of categories of protected area (strictly protected vs. sustainable use areas). We found 211 (63.17% of the 334) protected areas with management plan. On average, the time taken for the creation and approval of a management plan far exceeds the deadlines (5 yrs.) defined under current Brazilian law. All Brazilian biomes are poorly covered by protected areas with effective management plans, with the highest and lowest value observed in the Pantanal (100%) and Caatinga (46.42%), respectively. Our results suggest that the effectiveness of many federal protected areas in Brazil can be reduced considerably by the lack of a management plan, with deleterious consequences for the country’s principal conservation strategies.

The Creation

The wooded pastures arose from the colonisation of the valleys and high plateaux of the Jurassic Arc. They are the product of a mixed exploitation combining agricultural and silvicultural elements, and are dependent for their conservation on a form of management where a balance between cattle grazing and wood cutting is maintained. The abandon of farmland and fewer cattle at pasture in summer, the small returns from logging and the introduction of grants based on surface area of agriculturally used land (SAU) have together completely disturbed this balance. The necessity of an integrated management system which takes into account the interests of agriculture, silviculture, nature, landscape and leisure activities has led to the creation of interdisciplinary commissions on wooded pastures of the Bernese Jura and the Jurassic Arc. An Interreg IIIA project France-Switzerland has enabled the creation of a model integrated management plan. Due to the lack of funds from the Federal Office of Agriculture, the cantonal services promote the development of integrated management plans.

In Turkey, forest management plans are produced by terrestrial surveying techniques for 10 or 20 year periods, which can be considered quite long to maintain the sustainability of forests. For a successful forest management plan, it is necessary to collect accurate information about the stand parameters and store them in dynamic and robust databases. The position, number, height and closure of trees are among the most important stand parameters required for a forest management plan. Determining the position of each single tree is challenging in such an area consisting of too many interlocking trees. Hence, in this study, an object-based tree detection methodology has been developed in MATLAB programming language to determine the position of each tree top in a highly closed area. The developed algorithm uses the Canopy Height Model (CHM), which is computed from the Digital Terrain Model (DTM) and Digital Surface Model (DSM) generated by using the point cloud extracted from the images taken from a UAS (Unmanned Aerial System). The heights of trees have been determined by using the CHM. The closure of the trees has been determined with the written MATLAB script. The results show that the developed tree detection methodology detected more than 70% of the trees successfully. It can also be concluded that the stand parameters may be determined by using the UAS-based point clouds depending on the characteristics of the study area. In addition, determination of the stand parameters by using point clouds reduces the time needed to produce forest management plans.

The Impact

Purpose A co-produced clinical practice that aims to improve outcomes through a partnership with service users is becoming increasingly important in intellectual disability (ICD) services, yet these approaches are under-evaluated in forensic settings. This study aims to explore and compare the feasibility of two approaches to co-production in the completion of dynamic risk assessments and management plans in a secure setting. Design/methodology/approach A convenience sample of adults admitted to a secure specialist forensic ICD service (N = 54) completed the short dynamic risk scale (SDRS) and drafted risk management plans under one of two conditions. In the first condition, participants rated the SDRS and risk management plan first, separately from the multidisciplinary team (MDT). In the second condition, participants and MDTs rated the SDRS and risk management plan together. Findings In total, 35 (65%) participants rated their risk assessments and 25 (47%) completed their risk management plans. Participants who rated their risk assessments separately from the MDT were significantly more likely to complete the SDRS (p = 0.025) and draft their risk management plans (p = 0.003). When rated separately, MDT scorers recorded significantly higher total SDRS scores compared to participants (p = 0.009). A series of Mann-Whitney U tests revealed significant differences between MDT and participant ratings on questions that required greater skills in abstraction and social reasoning, as well as sexual behaviour and self-harm. Originality/value Detained participants with an intellectual disabilities will engage in their dynamic risk assessment and management plan processes. The study demonstrates the impact of different co-production methodologies on engagement and highlights areas for future research pertaining to co-production.

Abstract This study is based on a survey of 100 South Carolina nonindustrial private forest (NIPF) landowners who participated in the Forest Stewardship Program in 1995-1996. The purpose of the study was to determine which components in a management plan are most important to NIPF landowners. Most important are the landowners' objectives, followed by individual stand descriptions and a schedule of prescribed activities. Data are summarized by type of preparer (government, consultant, or industry) and by timber or nontimber primary management objective. South. J. Appl. For. 21(4):164-167.

Abstract Introduction The aims of this quality improvement project were to: (1) proactively identify people living with frailty and CKD; (2) introduce a practical assessment, using the principles of the comprehensive geriatric assessment (CGA), for people living with frailty and chronic kidney disease (CKD) able to identify problems; and (3) introduce person-centred management plans for people living with frailty and CKD. Methods A frailty screening programme, using the Clinical Frailty Scale (CFS), was introduced in September 2018. A Geriatric Assessment (GA) was offered to patients with CFS ≥ 5 and non-dialysis- or dialysis-dependent CKD. Renal Frailty Multidisciplinary Team (MDT) meetings were established to discuss needs identified and implement a person-centred management plan. Results A total of 450 outpatients were screened using the CFS. One hundred and fifty patients (33%) were screened as frail. Each point increase in the CFS score was independently associated with a hospitalisation hazard ratio of 1.35 (95% CI 1.20–1.53) and a mortality hazard ratio of 2.15 (95% CI 1.63–2.85). Thirty-five patients received a GA and were discussed at a MDT meeting. Patients experienced a median of 5.0 (IQR 3.0) problems, with 34 (97%) patients experiencing at least three problems. Conclusions This quality improvement project details an approach to the implementation of a frailty screening programme and GA service within a nephrology centre. Patients living with frailty and CKD at risk of adverse outcomes can be identified using the CFS. Furthermore, a GA can be used to identify problems and implement a person-centred management plan that aims to improve outcomes for this vulnerable group of patients.
