Study on Landscape Renovation Strategies for Old Blocks in Small Cities and Towns from the Cultural Perspective

Reasons for landscape environment damages and cultural loss of old blocks in small cities and towns were analyzed from the cultural perspective,i.e.regional cultures have not been given due attention or inherited effectively.On this basis,cultural connotations of landscapes in old blocks,and cultural inheritance-dominated renovation strategies were explored,i.e.focusing on man and culture,inheriting cultures in the overall town planning and constructing physical functions of old blocks.

The Community Renewal of Shantytown Transformation in Old Industrial Cities:Evidence from Tiexi Worker Village in Shenyang,China

There are many problems,such as poverty,unemployment,poor infrastructure and how to improve the ecological environment,in the shantytowns of old industrial cities.Shantytowns are the most centralized areas with different contradictions,referred to as the‘problem areas’of urban sustainable development.The shantytown transformation of old industrial cities is a typical process of unit community disintegration,which is reflected not only in the reconstruction of physical space but also in the community renewal of social spatial integration and culture reconstruction.Based on qualitative research,questionnaires and in-depth interviews,taking Tiexi Worker Village in Shenyang as a research case,this paper attempts to analyse the characteristics and driving forces of the community renewal of shantytown transformation in old industrial cities.We found that the physical space of Tiexi Worker Village has changed considerably,which is embodied in its land use structure,living environment and community service facilities,reflecting the development of community function from simple industrial function to comprehensive functions.The residents in this community have experienced a transformation from a period of homogeneity to one of heterogeneity.The social network of the community has been destroyed.Social stratification,social differentiation and higher fluidity have occurred.Community renewal is mainly affected by macro factors such as policy regulation,economic driving,condition constraints,and micro factors such as residents’choice of living space and willingness to renew their communities.The transformation policy of the old industrial zone and the development policy of the new urban area are the fundamental and deep-seated reasons for the renewal of Tiexi Worker Village,which determine the direction of the renewal and development of the community.The paid use of land and the development of the real estate industry are the direct stimulating factors for the renewal of Tiexi Worker Village,which become the direct reasons for the spatial transformation.The changes in the population in urban and rural areas and the promotion of traffic are the driving factors for the renewal of the community,while the choice of residents and their willingness regarding community renewal are the endogenous forces for promoting community renewal.Finally,the author attempts to put forward a model of the interlaced mechanism of the forming of community renewal at the macroscopic and microcosmic levels,which are the urban renewal and reconstruction and social space differentiation of community residents,respectively.

An Analysis of the Colonialism in The Old Chief Mshlanga from the Perspective of Narratology

Doris Lessing is one of the most influential writers in English. The colonialism, one of her most concerned topics, is often revealed in many of her early works and so is in The Old Chief Mshlanga. In this story, Lessing first employs a third-person narrator and then a first-person narrator, both of whom adopt the narrative perspective from the protagonist within the story.What the two different person-narrators really differ is in the narrative voice. The narrative voice of the third-person narrator comes from the narrator outside the story, while the other one comes from the protagonist within the story. It is by means of the same perspective and the different narrative voice that Lessing vividly reveals the colonialism in The Old Chief Mshlanga.

Dexmedetomidine-induced anesthesia in elderly patients undergoing hip replacement surgery

BACKGROUND A femoral neck fracture is a common and frequently reported issue in orthopedics, with a greater rate of incidence among the elderly. Due to their advanced age and the presence of some primary diseases, both anesthesia and surgery are increasingly difficult in elderly patients with a femoral neck fractures. In fact,general anesthesia can easily induce complications such as cognitive dysfunction,which is not conducive to postoperative recovery.AIM To analyze the efficacy of dexmedetomidine in inducing anesthesia for elderly patients undergoing hip replacement surgery.METHODS A total of 98 elderly patients undergoing hip replacement in our hospital from June 2020 to June 2021 were randomly divided into control group(49 cases) and observation group(49 cases). The control group was given general anesthesia, and the observation group was combined with dexmedetomidine for anesthesia on the basis of the control group. Both groups were observed until the patients were discharged. The vital signs, serum inflammatory factors and renal function indexes of the two groups were compared before, during and 6 h after operation.The postoperative recovery and adverse events of the two groups were statistically analyzed.RESULTS Compared with the mean arterial pressure of the two groups, the intraoperative and postoperative 6 h was higher than that before the operation, the intraoperative was lower than the postoperative 6 h(P < 0.05);the blood oxygen saturation of the two groups was higher than that before operation and 6 h after operation, and the observation group was higher than the control group 6 h after operation(P < 0.05). The heart rate of the two groups was lower during and 6 h after operation than that before operation, and higher at 6 h after operation than that during operation(P < 0.05).The levels of serum C-reactive protein, tumor necrosis factor-α, interleukin-1β and kidney injury molecule-1 in the two groups were higher during operation and 6 h after operation than those before operation(P < 0.05). The level of serum urea nitrogen in the two groups was higher than that before operation, and that in the observation group was lower than that in the control group(P < 0.05). During hospitalization, the first time of getting out of bed, recovery time of grade Ⅱ muscle strength, recovery time of grade Ⅲ muscle strength and hospitalization time in the observation group were shorter than those in the control group(P < 0.05).CONCLUSION Dexmedetomidine can effectively improve the vital signs of elderly patients undergoing hip replacement surgery, reduce the body’s inflammatory response and renal function damage, and promote postoperative recovery. Meanwhile, dexmedetomidine showcased a good safety profile and a good anesthetic outcome.

Improving the Use of Insecticide-Treated Nets among Children under Five Years Old in Benin, West Africa

Background: In Benin, malaria represents the first cause of consultation and hospitalization (48% for children under 5 years old) in health units. It also accounts for 23.1% of deaths recorded in health facilities (MoH, 2019). Between the two main components of vector control adopted by Benin government, the mass distribution campaigns of Insecticide-Treated Nets (ITNs) remained the only proven cost-effective way to rapidly achieve high and equitable coverage (WHO, 2017). After the fourth mass distribution campaign conducted in 2017, the Demographic and Health Survey (DHS) data indicated that the percentage of children who slept under an ITN has increased from 20% in 2006 to 70% in 2011-2012 and to 76% in 2017-2018 while the incidence of malaria (tested positive) is increasing rapidly among children under 5 years old, growing from 36.5% in 2009 to 28.8% in 2012 and then to 51.4% in 2019. This study aims to understand this contrast by identifying the origin of the increase in ITN use over time among children under five years old and the factors which determine this use. Methods: Data from the Demographic and Health Survey (DHS) conducted in Benin respectively in 2006 and in 20018 were used during the analysis, which covered 13,445 children under five years old from 2006 DHS and 12,255 children from 2017-2018 DHS. Firstly, the data were analyzed using decomposition method to highlight the origin of the increase of ITN use over time among children under five years old. Secondly, the chi-square test analysis estimated the association between ITN use and some characteristics (wealth index, maternal or caregiver education level and child age). Finally, the logistic regression model was used to identify the main factors, which influence the net use over the study period. Results: This study shows that the improvement of basic conditions is the main origin of behavior change in the use of ITNs among children under five years old. This improvement of the basic conditions consists of making ITNs available in households and informing household members about the benefits of ITN use. So, the free ITN distribution campaigns, routine distribution, awareness campaigns about the benefits of ITN use are the strategies, which increase the household capacities and knowledge, allowing household members to make their children sleep under net. The analysis also shows that region of residence, wealth index of household, household size, religion, and child age continue to determine the ITN use among children under age 5 years old and MNCP will integrate the factors in malaria prevention strategies in order to achieve universal use of ITNs. Conclusions: Although, sleeping under ITN behavior has indeed spread among children under 5 years old, policymakers and other stakeholders should design strategies to maintain and improve the current level of ITN use to reach the collective protection threshold (80% according to WHO). Therefore, to address the challenges of universal use of ITN, the study recommends expanding the routine distribution system to private sector health centers;discussing issues related to health service utilization (particularly ITN use) within a consultation framework at the communal level. In addition, collecting qualitative and quantitative data in the Oueme region will allow better understanding of all aspects of the ITN use gap among children under 5 years.

Optimization of Extraction Process of Polyphenols from Chrysanthemum morifolium and the Development of Chrysanthemum Rice Wine

[Objectives]This study was conducted to provide a theoretical basis for the extraction and comprehensive utilization of functional active components of Chrysanthemum morifolium polyphenols.[Methods]With C.morifolium as a raw material,polyphenols were extracted by water extraction.The extraction process of polyphenols were optimized by single factor tests on solid-liquid ratio,extracting time and times.Old rice wine selected as the base wine was added with C.morifolium polyphenol extract,honey,citric acid and other auxiliary materials to prepare a kind of chrysanthemum old rice wine.Through sensory analysis combined with fuzzy mathematics comprehensive evaluation method,the optimal formula of chrysanthemum old rice wine was determined,and the corresponding physicochemical indicators of the obtained chrysanthemum old rice wine were tested.[Results]The optimal soaking process for C.morifolium was as follows:extraction time of 20 min,a solid-liquid ratio of C.morifolium to warm water at 1:40,extraction times of 3 times.The physical and chemical indicators of the chrysanthemum wine obtained from the above optimal formula were as follows:sugar content 5%,ethanol content 11%,and pH value 4.04.The chrysanthemum old rice wine obtained was clear and transparent,and the fragrance of chrysanthemum was coordinated with the mellow aroma of rice wine.The taste was refreshing and suitable for the vast majority of people to drink.[Conclusions]The new type of chrysanthemum old rice wine combines the polyphenolic active substances in C.morifolium with the low ethanol content of old rice wine,which not only improves the utilization rate of C.morifolium,but also strengthens the health function of old rice wine products,improves the quality of old rice wine,and promotes the healthy and rapid development of the old rice wine industry.

Application of the Concept of“Endowing the Old with the New”in Urban Renewal

The renewal of ancient cities is an important part of the urban renewal work in China.However,there are few studies on the general historical ancient cities at the county level in China,and there is no guidance on the renewal path.Through the practice of the renewal design project of Suining County,Xuzhou City,it makes an exploratory study on the renewal concept and mode.It first interprets the connotation and implementation path of the renewal concept of“endowing the old with the new”.Based on the texture analysis of the ancient city of Suining,it finally determines the design theme that tracing the historical context of the ancient city.Using the renewal techniques such as“extraction-transformationactivation”,through the renewal strategies such as“building new space,shaping new landscape,inheriting new culture and pregnant with new environment”,it realizes the regeneration of urban historical context and meets the needs of residents'modern life,so as to provide reference and guidance for the renovation of general historical ancient cities at the county level in China.

Old canalicular laceration repair:a retrospective study of the curative effects and prognostic factors

AIM： To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. METHODS： A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS： Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old （ranged from 3 to 63 years old）. The 110 patients （74.32%） were male and 127 patients （85.81%） were adults （__.18 years old）. The old upper, lower, and bicanalicular lacerations were found in 5 （3.38%）, 39 （26.35%）, and 104 patients （70.27%）, respectively. The mechanism of old injury was primarily due to motor vehicle accidents （n=53, 35.81%）. The mean time from injury to repair was 43.61mo （ranged from 1 to 360mo）. Associated old ocular and orbit injuries were found in 65 patients （43.92%）, and chronic dacryocystitis in 18 patients （12.16%）. The main cause of delayed repair was that doctors or patients didn＇t pay attention to the canalicular laceration because of the concurrent severe injuries （n=71, 47.97%）. Totally 136 patients （91.89%） with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients （13.51%） were combined with dacryocystorhinostomy. In these cases, 132 patients （97.06%） attained anatomic success, 121 patients （88.97%）reported no epiphora （functional success）, 11 patients （8.09%） reported significant epiphora anesis （functional improvement）, and 4 （2.94%） reported no significant anesis （functional failure）. Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair. CONCLUSION： The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration.

Urban Repair Routes Toward Cultural Tourism:A Case Study of the Old Town of Jiazhou in Leshan,Sichuan

Cultural tourism is one of the directions of urban transformation and development,but there are still problems such as fragmentation of resource development models.Urban repair,as a comprehensive,systematic,and holistic updating project under the guidance of the problem,is an important way to promote the sustainable development of urban cultural tourism by paying attention to the connotative development of the "stock" of urban scale.Based on the analysis of the western urban cultural renaissance concept,this study closely followed the actual situation of cultural tourism development in the old city of China,re-examined the scale,goals and values of the current urban repair research to find breakthroughs for urban repair,put forward basic routes for the renewal of the built-up area,and analyzed the project practice of the Old Town of Jiazhou,with a view to providing a new "repair" model for promoting cultural tourism in small and medium-sized cities in China.

Rural migrants' participation in old-age insurance: a case study of the inter-provincial migrant workers from Sichuan, China

Old-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers' participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants' behavior participating(or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes among migrant workers are drawn from the findings.

EFFECT OF HEALTH-PRESERVING MOXIBUSTION ON PLASMA TESTOSTERONE AND ESTRADIOL OF THE OLD PEOPLE

In the present paper, changes of plasma testosterone and estradiol contents after moxibustion were analyzed in the old subjects. Results show that plasma testosterone of the old male subjects and estradiol content of the old male and female subjects rise following moxibustion. It indicatesthat moxibustion can regulate the functional state of the hypothalam us-hypophysis- sexual glang axis,improve neuroendocrine disorder, prevent the sexual glang from atrophy and delay senility. Increase ofthe two hormones in the human body can lead to a series of regulations in other respects. Therefore,moxibustion is of an important role in delaying senility.
