2020 and beyond - Connotation for refractive surgery.

Abstract: The year 2020 was important for ophthalmologists as it is symbolic of “20/20 Vision” denoting normal visual acuity. Several goals were set at the turn of the century with Vision 2020 aimed at eliminating avoidable blindness by targeting leading causes of visual impairment such as cataract, trachoma, onchocerciasis, childhood blindness (including vitamin A deficiency), refractive errors and low vision, and the target year of attaining them was 2020.[1-4] The “Universal eye health” initiative was aimed at best quality eye care for all and across socioeconomic barriers with a specific target of a 25% reduction in the prevalence of avoidable visual impairment by 2019 (compared to the baseline in 2010).[5] Keeping with the theme, the beginning of this year saw many organizations planning initiatives to mark the symbolism of 2020,[6,7] and as we come to the end of a fateful year, we must look ahead to fulfill and achieve those aims of mitigating blindness.

The Planning and Construction Path of Innovative and Intelligent Park Cities Based on Big Data Technology

Abstract: By analyzing the historical background of the times and summarizing the current situation of urban development research at home and abroad, we find that there is a lack of theoretical and practical research related to intelligent park cities. Therefore, this paper first starts with the connotation of park city theory, focuses on the improvement of planning methods, and studies the application paths of big data technology in the planning and construction of park cities. Taking Jinzhai Country as the research object, this paper further illustrates the applicability of this research method at the macrolevel. In the context of the park city, we analyze the problems of the current status of city construction in general and explore the path of “planning concept first, big data-assisted design” for innovative and intelligent city construction. According to the study, the overlook corridor control has an impact on the building height. In terms of landscape protection, overlook system simulation is the other key factor. In addition, the analytic hierarchy process is the basis for development intensity control. The results show that big data technology can assist in the landscape conservation, morphology formation, and efficient operation of Jinzhai Country Park City. Our aim is to achieve the protection and utilization of its ecological environment and natural resources and thus to comprehensively coordinate the multidimensional urban spaces and build a park city model. As an urban development model that meets the requirements of being “people-oriented, efficient, green, and aesthetic” in the new stage, park cities need to be faced by researchers in order to further realize the overall city goal and vision for the whole society to be smart. It also provides relevant design ideas and methods for the planning and construction of park cities in other similar cities or regions.

Disaster-Causing Mechanism of Hidden Disaster-Causing Factors of Major and Extraordinarily Serious Gas Explosion Accidents in Coal Mine Goafs

Abstract: Hidden disaster-causing factors (HDCFs) in coal mines can be identified via the rerefinement and classification of disaster-causing factors (DCFs) in coal mines. The study of the disaster-causing mechanism of accidents from the perspective of HDCFs in coal mines could be helpful to analyze the accident occurrence process from a new perspective, and new ideas for accident prevention and control could then be proposed. To clarify the disaster-causing mechanism of HDCFs of major and extraordinarily serious gas explosion accidents (MESGEAs) in coal mine goafs, 32 MESGEAs in coal mine goafs in China from 2000 to 2021 were adopted as a data source. By redefining the definition, connotation and characteristics of HDCFs in coal mines, 10 HDCFs were identified. Consequently, an improved decision-making trial and evaluation laboratory (DEMATEL)-interpretive structural model (ISM)-matrix of cross impact multiplications applied to classification (MICMAC) model was used to comprehensively analyze HDCFs in 3 aspects, including the centrality and cause degrees, hierarchical structure, and driving and dependence powers, from a completely objective perspective. The results demonstrated that (1) the considered MESGEAs in coal mine goafs were caused by DCFs in the management aspect by affecting the DCFs in the 3 aspects of human factors, equipment and environment, as well as under the combined effect of DCFs internal interaction contained in itself. (2) There were 2 types of disaster-causing mechanisms of HDCFs of MESGEAs in coal mine goafs: (a) the indirect disaster-causing by HDCFs in the management aspect and (b) the random coupling disaster-causing by HDCFs in human factors, equipment and environment 3 aspects.

Jakarta’s urban culture representation on social media @jakarta_tourism: A semiotics analysis

Abstract: Social media can form the identity of the representation content. The content of the Instagram account @jakarta_tourism represents the identity of the urban culture of Jakarta as a tourism brand. This study aims to find out and reveal the representation of Jakarta as a city of urban culture, based on the signs from the content of the Instagram account @jakarta_tourism. This study is descriptive qualitative using the constructivist paradigm using the semiotic analysis method by Roland Barthes. The main focus of the semiotic analysis by Roland Barthes is to find the meaning of denotation, connotation, and myth of a sign. The results in this study indicate that some content of the Instagram account @jakarta_tourism represents Jakarta as a city of urban culture and highlight that as part of the brand of Jakarta Tourism. That was revealed after this research analyzed using syntagmatic and paradigmatic studies on posts of Instagram account @jakarta_tourism to find the meaning of denotation and connotation/ myth. As for the myth, it is shown that the concept of urban culture is closely related to acculturation forms of urban culture and urban society and space to express various arts and cultures.

On Social Service Functions of District Universities

Abstract: There have been four functions for nowadays universities: talent cultivation, scientific research, social service and cultural passing and creation. The social service function is the major one among the four because the position of school running, which is to foster application type talents and the role of district economy in social development. The article states the functions, the connotation and the aims of the district universities. Key words: District university; Social service; Connotation; Aims
