“…Through analysis of the relevant literature and summary of one’s own work experiences, we found that many patients maintain a good mental state during hospitalization, but after discharge they voluntarily suspend medication or do not adhere to medication, which increases the recurrence rate of the disease and reduces patients’ quality of life [ 11 ]. In order to improve this problem, clinical staff urgently needed to develop a more systematic, comprehensive out-of-hospital nursing system to ensure that patients still have high medication compliance after discharge and ensure stable mental state [ 12 ].…”

AbstractObjectiveThis paper aims to explore specific effects of out-of-hospital continuing nursing on schizophrenia patients’ health rehabilitation and quality of life, and further improve application and popularization of out-of-hospital continuing nursing.MethodsThe 180 schizophrenia patients discharged from our hospital from March 2014 to March 2016 were selected as the subjects. The patients were divided into two groups according to the randomized double-blind method. Both groups received routine discharge guidance, and the observation group received out-of-hospital continuing nursing on this basis. Questionnaires and scales were used to compare differences of the two groups after discharge from hospital, such as medication compliance, recurrence rate of schizophrenia, awareness of health knowledge and quality of life.ResultsAfter 6 months of nursing for the observation group, complete medication compliance rate was 71.11% (64/90), awareness rate of schizophrenia-related health knowledge was 96.67% (87/90), and recurrence rate was 8.89% (8/90). For the control group, complete medication compliance rate was 45.56% (41/90), awareness rate of schizophrenia-related knowledge was 46.67% (42/90) and the recurrence rate of disease was 26.67% (24/90). Hence, the observation group enjoys significant advantages compared with the control group. Statistical analysis (P <0.05) showed statistical significance; In addition, life quality scores showed that the quality of life of the observation group was obviously better than the control group; the difference was statistically significant (P <0.05).ConclusionOut-of-hospital continuing nursing for schizophrenia patients after discharge can effectively improve medication compliance, awareness rate of health knowledge, effectively reduce incidence of schizophrenia and improve the quality of life of patients. Thus, the nursing concept and related methods are worthy of publicity and application in a wider range.

“…Tidal forecast is helpful for safe operation of large ports. The 12.5m deep water channel [33] in Jiangsu section of the Yangtze River has been perfected and the navigation environment has been improved. The 150,000-ton ships entering and leaving ports in Jiangsu section of the Yangtze River will normalize.…”

The navigation environment of the Jiangsu section of the Yangtze River is complex, and the full utilization of port water depth resources is an important guarantee for navigation safety and a favorable condition for accurate tidal forecasting. Improving pilotage safety, tidal forecasting is crucial for ship navigation safety, port operation efficiency, and nearshore engineering. Tidal forecasting can help ensure the safe operation of large ports. At present, various numerical models used domestically and internationally only focus on the impact of tides and currents in coastal areas. There is little research on tidal optimization in narrow and curved long channels such as the Jiangsu section of the Yangtze River, and there are also few researchers using MIKE software to simulate and simulate tidal levels, flow velocities, and flow directions. This article provides a comprehensive study on tidal optimization models and algorithms, the current research status at home and abroad, the problems that need to be solved in tidal optimization, and Mike21.

“…Studies of the influences of human activities on tidal creeks have focused on various aspects of the tidal creek response. Regarding the morphology characteristics and connectivity, the responses of tidal creeks to upstream construction (Chen et al, 2013a), land reclamation (Shi et al, 2016;Xie et al, 2020;Fan et al, 2021), or other coastal developments (Chen and Han, 2015;Xie et al, 2020;Fan et al, 2021) have been studied, including the sedimentary changes to land use (Sanger et al, 2004;Darrow et al, 2017-). Regarding the water environment, the variations in water quality due to the influence of pollution have been studied using simulations (Buzzelli, 2008;Boynton et al, 2014) and experiment methods (DiDonato et al, 2009;Boynton et al, 2014;Wessel et al, 2021).…”

Quantitative evaluation of sea reclamation activities on tidal creek connectivity

Deltas are in a dynamic balance due to the impact of fluvial and coastal flooding, and hydrological connectivity plays an important role. In recent decades, the dynamic equilibrium has been influenced by upstream and local human activities, including sea reclamation activities. However, in most instances, the influence of human activities has not been explicitly distinguished and quantified in detail. In this paper, the influence of sea reclamation activities on hydrological connectivity in the Yellow River Delta was quantified by parameterizing the resistance surfaces (a spatial layer that assigns a value to each landscape feature, indicating the degree to which that variable impedes or promotes movement) that includes sea reclamation activities. By optimizing a functional relationship between landscape features and hydrological connectivity (water flow movement patterns), the values in the resistance surfaces could be assigned. We first calculated hydrological distances among bifurcations from 1985 to 2020 with a 5-year interval representing the hydrological connectivity of each tidal creek. The sea reclamation activities in the YRD were classified into four: reclaimed land, sea enclosure activity, freshwater resource facilities, and engineering in the oil field to create resistance surfaces. We identified that the periods of 1990–1995 and 2000–2005 were under the most severe influence of sea reclamation activities. Sea enclosure activity, freshwater resource facilities, and engineering in oil fields played major roles in composing resistance surfaces. Mariculture (quantified relative resistance value, 1.00), reservoir (0.92), agriculture (0.91), and river (0.97) were the features with the highest resistance values in the initial and mature development stages. The formation of resistance (costs to movement) was due to human activities and natural factors, for example, the evolution of tidal creeks. To develop the resource in tidal flats sustainably, systematic monitoring and sufficient conservation awareness were required. This study contributed to coastal management and planning by providing a quantified assessment of different types of sea reclamation activities.
