Published: January 2020

Abstract
Background: Temporal difference in activation of medial-lateral hamstrings could lead to external tibial rotation. It was assumed that patients with patellofemoral pain syndrome (PFPS) exhibit altered medial-lateral hamstrings muscular pattern during functional tasks.
Objectives: The aim of this study was to compare the electromyography (EMG) activity of quadriceps and hamstrings in patients with PFPS and healthy subjects during stair descending.
Design: cross sectional comparative study
Setting: Motion analysis Lab, Rehabilitation research center, Shiraz University of Medical Sciences
Participants: 24 women with PFPS and 24 healthy subjects, aged 18-40 years recruited through convenience sampling method participated in this study.
Interventions: The EMG activity of vastus medialis obliqus (VMO), vastus lateralis (VL), medial (MH) and lateral hamstrings (LH) recorded during stair descending.
Main outcome measures: Onset latency and intensity of muscle activity measured relative to the moment of foot contact.
Results: There were statistically significant difference in onset of hamstrings heads (LH-MH) between groups (p=0.014). The BF activated before ST in PFPS group. Normalized muscular activity was significantly reduced for VMO (p=0.002), VL (p=.045), and LH (p=0.019) in PFPS patients.
Conclusions: Difference in temporal activation patterns of BF and ST may result in lack of rotational knee stabilization and lead to increased patellofemoral joint pressure. Earlier activation of LH rotates tibia externally, and hence, produced lateral patellar tracking.

Abstract
BACKGROUND: The financial burden of prosthetic joint infection after joint replacement in developed countries is well known. There is a need to evaluate the economic burden in developing countries like Pakistan. MATERIALS AND METHODS: Cases performed during this study are divided into two groups. 1. Uneventful primary total knee arthroplasty. 2. Prosthetic joint infection treated with two stage revision. Categorical variables were compared through Chi-square and Fisher Exact test. Continuous variables were compared using Mann-Whitney test. Multivariable regression analysis was done to identify the variable that places major financial burden on patient economy. RESULTS: The total cost of revision surgery for prosthetic joint infection considering twice hospitalization is found to be 7, 91, 353 ± 89,136 rupees. The total cost of uneventful arthroplasty is found to be 3, 50, 289± 32,123 rupees. We observed significant difference with respect to economic details between two groups. CONCLUSION: Measures should be undertaken to reduce PJI by encouraging healthcare providers to consider evidence based protocols to prevent PJI and financial constraints associated with these events.

Abstract
Background: Improving health literacy is the key to chronic disease prevention and improved interventions. However, little is known about the status of health literacy and its influencing factors in patients with chronic diseases. Accordingly, this study aimed to explore the different aspects and factors influencing health literacy among patients with chronic diseases in Chongqing, China.Methods: A cross-sectional survey was conducted in areas of Chongqing using the 2018 National Questionnaire on Health Literacy of Residents administered to 27,336 patients with chronic diseases. The research investigated the prevalence and factors of health literacy in patients with chronic diseases in Chongqing, China using χ 2 tests and logistic regression analysis.Results: Among the participants (n = 27,336), 51.3% were males and 48.7% were females. Only a small number of patients with chronic diseases were health literate (21.6%). Regression analyses indicated that inadequate health literacy was associated with rural area residents (OR: 0.92), minorities (OR: 1.31), farmers (OR: 1.18), nonlocal registered permanent residents (OR: 1.05), and patients with self-rated unhealthy status (OR: 1.80). Patients with chronic diseases aged 25–34 (OR = 1.18) and 35–44 (OR = 1.18) were more likely to have health literacy than patients with chronic diseases aged 65–69. Illiterate or slightly literate patients (OR = 0.10) were less likely to have health literacy than patients who were in the junior college or had a bachelor’s degree or above. Patients with an average annual household income of less than 3,000 yuan (OR = 0.65) were all less likely to have health literacy than patients with an average annual household income of more than 15,000 yuan.Conclusions: Health literacy of patients with chronic conditions remains at a low level and varies significantly with their demographic and sociological characteristics. Therefore, developing and adopting appropriate health promotion programs would be necessary to improve the health literacy of all patients with different types of chronic diseases.

Published: January 2020

Abstract
With the development of communication network and computer software and hardware technology, especially the emergence of high-precision and high-resolution image sensors, the photography and measurement technology of aerial image have played an increasingly important role in today's geological survey. The traditional aeronautical measurement is carried out by a large manned aircraft. The collected measurement information has a large capacity and a wide shooting range, which is suitable for large-area operations. This type of measurement requires high hardware requirements and is expensive, and it is not suitable for small areas. UAV aerial measurement system is used to measure the small areas, UAV is in small size, with great flight fluctuation, but the data image collected is not accurate enough. In this paper, the common algorithms of image fast matching are compared to conduct in-depth research on gray-level matching and feature-based matching, and SIFT feature matching algorithm based on feature matching is proposed to obtain the measurement image as consistent as possible with the actual scene. The main features of the object to be measured can be obtained through the actual surface area image measurement test, which is of practical significance in the practical low-altitude small area surveying and mapping.

Authors: Wang Zhongsheng , Xie Jianping , Lin Zhao , Zhong Wei 
Published: January 2020

Abstract
The current global Internet USES the TCP/IP protocol cluster. IP is the network layer protocol and the core protocol in this protocol family. The current version is IPv4 with 32-bit addresses. With the popularity of Internet applications, the limited address space defined by IPv4 has been exhausted. To expand the address space, the Internet Engineering Task Force (IETF) has designed the next generation IP protocol, IPv6, to replace IPv4. IPv6 redefines the address space, using a 128-bit address length that provides almost unlimited addresses. However, with the development and application of the Internet of things, big data and cloud storage, IPv6 has some shortcomings in its address structure design, security and network sovereignty, so it is urgent to develop a new generation or future internet with security and reliability, autonomy and controllable, and it becomes a research hotspot in the world.
This paper developed a new generation Internet (IPV9) datagram by researching the existed IPv4 and IPv6, and it is based on the method of assigning addresses to computers connected to the Internet by full decimal character code which designed by the Chinese Decimal Network Working Group with the leader of Xie Jianping. It is a subsequent version with RFC1606, RFC1607, a new generation of network data structure, it is not the updating of IPv4 [RFC - 791] and IPv6 [RFC - 1883], [RFC - 2464], it is a new vision to demonstration and testing.

Abstract
To solve a series of problems caused by address space and information security of contemporary Internet, Chinese scientists have proposed a new generation of network architecture. Since the release of IPv4 RFC791 in 1981, it has become the first widely used Internet of things protocol due to its characteristics of easy implementation and good operability. It constitutes the basic protocol of current Internet technology. However, due to the defects in address classification, address resources are largely wasted. As the scale of the Internet continues to grow, especially the number of addresses used to surge, the address shortage has limited the Internet further development. IPv6 has solved the problem of insufficient IPv4 addresses to some extent, but it is not widely for more than 20 years used because it integrates the information of physical layer and application layer, which confuses the network layer and brings many security risks. Based on the study of IPv4 and IPv6, this paper proposes a new generation network architecture, which is designed from the aspects of addressing model, address writing, address prefix writing and address type. The address structure is compatible with IPv4 and IPv6, so that the previous design results can be retained, fundamentally solve the space address and information security issues, and provide a new solution for the next generation of Internet applications and research.

Authors: Lou Peide , Xu Fei 
Published: January 2020

Abstract
The share of the network economy has already accounted for 22% of China’s GDP, and its importance is self-evident. The two biggest problems involved in the network are network sovereignty and broadband charges, and the sovereignty of cyberspace is the “life gate” of the network. China’s cyber sovereignty is subject to the United States, resulting in political oppression, security, and economic exploitation. Therefore, without cyber sovereignty, there would be no national security without cyber security. IPV9 has become the key to China’s acquisition of network sovereignty. It is not only a technological innovation, but also related to national security and various cost savings, and can realize the autonomy and control of the network.

Abstract
Network system structure is the basis of network communication. The design of network model can change the network structure from the root, solve the deficiency of the original network system, and meet the new demand of the future network. TCP/IP as the core network technology is successful, it has shortcomings but is a reasonable existence, will continue to play a role. Considering the compatibility with the original network, the new network model needs to be compatible with the existing TCP/IP four-layer model, at the same time; it can provide a better technical system to implement the future network. Based on the Internet three-layer/four-layer hybrid architecture TCP/IP/M and ISO/IEC next-generation Internet standard solutions, this paper proposes the IPV9 system architecture, which can directly transmit audio and video data with three layers on the premise of not affecting the existing four-layer network transmission. The hybrid structure is a new transmission theory, which requires the establishment of a link before data transmission and the withdrawal of the link after the transmission is completed. It solves the problem of high-quality real-time media communication caused by the integration of three networks (communication network, broadcasting network and Internet) from the underlying structure of the network, realizes the long-distance and large-traffic data transmission of the future network, and lays a solid foundation for the digital currency and virtual currency of the Internet. The system framework is verified by practical application. It have been deployed to verify the compatibility and reliable transmission between IPV9 network and the existing network, under the independent, reliable, secure and controllable network architecture, a new generation of master root server and 13 root domain name servers.
Comparative Research on Key Technologies from IPv4, IPv6 to IPV9
Authors: Huai Sun , Zhang Liu 
Published: January 2020

Abstract
Since the United States developed the IPv4 protocol based on TCP/IP in the 1970s, it has been more than 30 years old. IPv4 is the “fourth edition of the Internet Protocol.” From a technical point of view, although IPv4 has a brilliant performance in the past, it seems to have revealed many drawbacks. With the addition of multimedia data streams and security considerations, IPv4’s address space is running out of crisis, and IPv4 is no longer sufficient. Under such circumstances, IPv6 was born as needed. When designing IPv6, not only the IPv4 address space was expanded, but also the parties to the original IPv4 protocol were reconsidered and a lot of improvements were made. In addition to the large number of addresses, there is higher security, better manageability, and better support for QoS and multicast technologies. It is an abbreviation for “6th Edition of Internet Protocol.” IPV9 was proposed in 1992 to replace the IPv4 with the ISO/OSI CLNP protocol, using the 20B NSAP address and the platform for the available OSI transport protocol. Later, DDNS was introduced and gradually developed into an IPV9 decimal network with a 256-bit address. IPV9 masters “the right to control the use of the Internet, the allocation of IP addresses, the initiative of information monitoring, the right to use routing protocols, and the ownership of technology patents.” Therefore, the research and application of a new generation of Internet Protocol Next Generation has become a worldwide hotspot.
Towards a definition of multiple and complex needs in children and youth: Delphi study in Flanders and international survey
Authors: Van den Steene Helena , van West Dirk , Glazemakers Inge 
Published: January 2020

Abstract

Background:
Multiple and complex needs (MCN) in children and youth jeopardize their development and pose significant challenges to the different professionals they meet. However, there is no agreed-upon definition of this vulnerable population.

Objectives:
To develop a definition of ‘MCN in children and youth’ that is meaningful for all professionals involved in care delivery for this population.

Method:
A cross-sector, multidisciplinary, and geographically spread panel of 47 experts representing mental health, youth care, juvenile justice, and education in Flanders participated in an online Delphi study. Qualitative analysis of answers in the first round yielded four definition possibilities that participants then ranked in the second round. In the last round, participants rated their agreement with the highest ranked definition. An additional survey asked 25 international experts to rate and comment their agreement with the final definition.

Results:
The final definition was: Children and adolescents with profound and interacting needs in the context of issues on several life domains (family context, functioning and integration in society) as well as psychiatric problems. The extent of their needs exceeds the capacity (expertise and resources) of existing services and sequential interventions lead to discontinuous care delivery. As such, existing services do not adequately meet the needs of these youths and their families. Cross-sector, integrated and assertive care delivery is necessary for safeguarding the wellbeing, development and societal integration of these young people. Response rates to the three Delphi rounds were 76.6, 89.1, and 91.3%. The definition was widely endorsed among Flemish (93.2% agreement) and international experts (88% agreement).

Conclusion:
A definition of MCN in children and youth was constructed using the Delphi method and further evaluated for international relevance in an additional survey. Such an agreed-upon definition can be valuable for optimizing care delivery and conducting research.
Glucagon and Glucagon-like Peptide-1 Receptors: Promising Therapeutic Targets for an Effective Management of Diabetes Mellitus
Authors: Abbas Ghulam , Haq Quazi M. I. , Hamaed Ahmad , Al-Sibani Mohammed , Hussain Hidayat 
Published: January 2020

:
G-protein-coupled receptors (GPCRs) are membrane-bound proteins, which are responsible for the
detection of extracellular stimuli and the origination of intracellular responses. Both glucagon and glucagon-like
peptide-1 (GLP-1) receptors belong to G protein-coupled receptor (GPCR) superfamily. Along with insulin, glucagon
and GLP-1 are critical hormones for maintaining normal serum glucose within the human body. Glucagon
generally plays its role in the liver through cyclic adenosine monophosphate (cAMP), where it compensates for
the action of insulin. GLP-1 is secreted by the L-cells of the small intestine to stimulate insulin secretion and
inhibit glucagon action. Despite extensive research efforts and the multiple approaches adopted, the glycemic
control in the case of type-2 diabetes mellitus remains a major challenge. Therefore, a deep understanding of the
structure-function relationship of these receptors will have great implications for future therapies in order to
maintain a normal glucose level for an extended period of time. The antagonists of glucagon receptors that can
effectively block the hepatic glucose production, as a result of glucagon action, are highly desirable for the tuning
of the hyperglycemic state in type 2 diabetes mellitus. In the same manner, GLP-1R agonists act as important
treatment modalities, thanks to their multiple anti-diabetic actions to attain normal glucose levels.

:
In this review article, the structural diversity of glucagon and GLP-1 receptors along with their signaling pathways,
site-directed mutations and significance in drug discovery against type-2 diabetes are illustrated. Moreover,
the promising non-peptide antagonists of glucagon receptor and agonists of GLP-1 receptor, for the management
of diabetes are presented with elaboration on the structure-activity relationship (SAR).
