AbstractRegional networks of Global Navigation Satellite System (GNSS) stations cover seismically and volcanically active areas throughout the United States. Data from these networks have been used to produce high-precision, three-component velocity fields covering broad geographic regions as well as position time series that track time-varying crustal deformation. This information has contributed to assessing interseismic strain accumulation and related seismic hazard, revealed previously unknown occurrences of aseismic fault slip, constrained coseismic slip estimates, and enabled monitoring of volcanic unrest and postseismic deformation. In addition, real-time GNSS data are now widely available. Such observations proved invaluable for tracking the rapidly evolving eruption of Kīlauea in 2018. Real-time earthquake source modeling using GNSS data is being incorporated into tsunami warning systems, and a vigorous research effort is focused on quantifying the contribution that real-time GNSS can make to improve earthquake early warnings as part of the Advanced National Seismic System ShakeAlert system. Real-time GNSS data can also aid in the tracking of ionospheric disturbances and precipitable water vapor for weather forecasting. Although regional GNSS and seismic networks generally have been established independently, their spatial footprints often overlap, and in some cases the same institution operates both types of networks. Further integration of GNSS and seismic networks would promote joint use of the two data types to better characterize earthquake sources and ground motion as well as offer opportunities for more efficient network operations. Looking ahead, upgrading network stations to leverage new GNSS technology could enable more precise positioning and robust real-time operations. New computational approaches such as machine learning have the potential to enable full utilization of the large amounts of data generated by continuous GNSS networks. Development of seafloor Global Positioning System-acoustic networks would provide unique information for fundamental and applied research on subduction zone seismic hazard and, potentially, monitoring.

Authors: Rhim Yongtaek , Kim Deokjin 
Published: September 2019

Purpose: This study was to investigate the difference in leadership skill depending on the preference of risky play in Korean children.
Methodology: In order to archive that purpose, we have collected data from 381(215 male and 166 female) Korean elementary school students, upon distributing papers of questionnaire which is composed of Preference to Playing Forms Scale for Children and Scale to Research and Evaluate Youth Leadership Life Skills Development and performed statistical analysis using SPSS.
Main Findings: The children who prefer risky play more showed significantly higher scores in all sub-factors of leadership skill such as communication, decision making, human relationship, solving problem, positive belief and consideration than the children who prefer risky play less.
Implications: This can mean that the leadership skill of the children who prefer risky play more is superior to that of the children who prefer it less. Therefore it can be suggested that children’s participating in well-controlled risky play be an effective method to develop their leadership skill.

Química analítica básica
Authors: Andrade João Carlos de 
Published: September 2019

A maioria dos estudantes de Química sempre foi induzida a pensar e a trabalhar os equilíbrios iônicos em solução aquosa usando o tratamento algébrico tradicional, como nos exemplos mostrados recentemente para equilíbrios ácido-base [1-3]. Entretanto, a solução algébrica exata deste tipo de problema frequentemente requer a resolução de polinômios de mais altos graus. Por exemplo, o cálculo exato do pH de uma simples solução aquosa de um ácido monoprótico fraco requer a solução de uma equação cúbica e no caso de um ácido triprótico (ex.: ácido fosfórico), a solução de um polinômio de quinto grau [1,2]. Isto induz o uso de aproximações para simplificar o trabalho, o que sempre leva a resultados aproximados. Um outro procedimento proposto por Birk [4], que emprega uma formulação matricial baseada na extensão de reação, também pode ser utilizada para este propósito, mas é um método que exige conhecimentos mais aprofundados de química e de álgebra linear, razão pela qual não é apresentado em livros textos e também não será discutido neste trabalho. Uma abordagem alternativa, mais fácil, é a utilização de cálculos numéricos e a apresentação gráfica dos resultados, procedimento bastante facilitado pelo uso de planilhas eletrônicas. Isto permite uma visão geral do sistema ácido-base, reforça princípios importantes e permite o tratamento de uma ampla gama de sistemas químicos.

Colombia’s New Ambitions Include Caribbean and Shale Development, But Are They Achievable?
Authors: Zborowski Matt 
Published: September 2019

At some point during the first half of this year, Colombia replaced politically and economically crippled Venezuela as Latin America’s third-largest oil-producing country.
That put Colombia behind only Brazil and Mexico in the hydrocarbons-rich region, two nations on divergent paths in terms of oil flow. Since Brazil ended state-owned Petrobras’ monopoly and opened up its industry to international companies in the late 1990s, the country’s oil output has almost tripled as it found and tapped into its giant offshore presalt fields. Output from Mexico’s state-owned Pemex, meanwhile, has fallen to its lowest level since at least 1990, and President Andrés Manuel López Obrador is working to stymie energy reforms implemented in 2013 to rejuvenate industry in the country.
With the lessons of its resource-rich neighbors in mind, Colombia finds itself in a similar position where it must carefully choose a path forward for its industry or risk squandering great potential, or worse, losing what took years to build. The Andean country in the early 2000s overhauled its regulatory framework, reduced government take, and held licensing rounds with the intent of attracting foreign investment. Oil production subsequently rose to more than 1 million B/D before dropping amid the global industry downturn. Output in May averaged just short of 900,000 B/D.
The Colombian government is trying to build on the foundation established by those reforms by implementing a novel permanent, continuously open bidding process and exploring unconventional development. The aim is to replenish depleted oil and gas reserves and increase production. Based on its 2018 output, the country’s crude reserves are good for just 6.2 years, while its natural gas reserves would last 9.8 years, falling below the 10-year mark for the first time in decades, according to statistics from Colombia’s National Hydrocarbons Agency (ANH).
But Colombia has long been seen by the global industry as a petroleum province with upside that surpasses just incremental reserves and production gains. All of its liquids and nearly all of its gas production is extracted conventionally onshore, meaning its offshore and unconventional sectors are nascent. Colombia, which shares a more than 2000-km border with Venezuela, has proven petroleum systems that have produced oil and gas for a century, and the application of horizontal drilling and hydraulic fracturing offers huge promise.•
Maria Fernanda SuÁrez, Colombia’s minister of mines and energy, has said that unconventional development could triple the country’s oil and gas reserves. Standing in the way, however, has been public resistance to hydraulic fracturing, and pilot projects that would demonstrate its benefits are yet to get environmental approval. There is “game-changing potential—if the industry can get going with development,” said Ruaraidh Montgomery, research director at oil and gas research firm•Welligence Energy Analytics.
Evaluation of a Riser After 10 Years of GOM Service Life
Authors: Carpenter Chris 
Published: September 2019

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 28908, “Ten Years in the Water: Observation and Detailed Evaluation of a Riser After Extensive Service Life,” by Mike Tricarico, Vallourec; Chris O’Neil, Anadarko; and Thomas Peter, Vallourec, prepared for the 2018 Offshore Technology Conference, Houston, 30 April–3 May. The paper has not been peer reviewed. Copyright 2018 Offshore Technology Conference. Reproduced by permission.
As part of an effort to evaluate existing riser systems, an operator launched an inspection and testing program to investigate risers retrieved following well abandonment after a service life of nearly 10 years in the Gulf of Mexico (GOM). This represented a rare opportunity to evaluate the state of the threaded and coupled risers after such a long service life and assess the remaining longevity of the riser system. Specifically, it was a chance to observe and measure the effects of actual service life as opposed to calculated service conditions on the pipe and connections. The findings provided valuable insights into the future viability of similar riser systems.
Introduction
The Constitution truss spar was first placed in service in 2005. The spar featured six dry tree production risers with two subsea tiebacks. It operates in the Green Canyon region of the GOM in almost 5,000 ft of water. The production risers were run in 2006. In 2015, the decision was made to abandon several of the production dry tree wells. There was a high degree of interest in investigating the risers to assess remaining life. Special attention was paid to evidence of corrosion, cracking, or wear on the outer diameter (OD) or inner diameter (ID) of the pipe, along with water ingress into the connection causing any corrosion from seawater on the bare metal of the•connection. The complete paper includes a detailed discussion of the original design, testing, and first running; this synopsis will concentrate on post-service testing and assessment.
Riser Pulling, Evaluation, and Testing
Pulling and Review. In late 2015, on the basis of internal evaluation, the operator pulled several of the production risers. In order to validate the remaining life of the risers and to help in-form future decisions on the longevity of threaded and coupled risers, the operator then initiated a detailed review of the risers. The stress joints, tension joints, and first connectors after those joints were kept, along with several of the risers from the middle of the string. During the pulling operations, little evaluation of the state of the risers was possible; however, photographs of several of the connections were taken as they were pulled. Most notable was the lack of corrosion on the connection.

Abstract
Background: Multidrug-resistant tuberculosis (MDR-TB) has become a great threat to TB control around the world. In 2017, there were 889,000 new tuberculosis cases in China, and 31.1% were MDR/RR-TB (TB resistant to rifampicin). This study aims to explore the the molecular characteristics and factors associated with infection among different genotype MDR strains in Chongqing, China.

Methods: All the 230 MDR-TB isolates were genotyped using 24-loci mycobacterial interspersed repetitive unite variable number tandem repeat (MIRU-VNTR) method and multiplex real-time PCR melting curve assay of Rv2952 gene and mutT2 gene. Polymorphism and clustering analysis of each locus was carried out by BioNumerics Version 5.0.

Results: By genotyping, 83.0% (191/230) of the MDR-TB isolates were Beijing strains, among which 41.9% from the ancient Beijing genotype and 58.1% from the modern Beijing genotype. Based on 24-loci, the 230 MDR isolates were classified into 208 genotypes, among which 38 isolates belonged to 16 clusters. The clustering rate was 16.5%. The percentages of SM-resistant and EMB-resistant in Beijing genotype were significantly higher than those in non-Beijing genotype (P < 0.01). The Beijing genotype had a significantly high risk to be clustered than non-Beijing genotype (p < 0.01). The percentages of SM-resistant isolates in clustered group were significantly higher than non-clustered group (P < 0.01). According to 24-loci, the HGDI was 0.9988, and five loci (Qub11b, Qub26, Mtub21, MIRU26, Mtub04) have high discriminatory power (HGDI > 0.6), while 7 loci (MIRU4, MIRU23, Mtub34, MIRU20, Mtub29, MIRU2, MIRU24) showed negligible diversity (HGDI < 0.1). The percentage of clustered rate showed no difference between 24-loci and 15-loci (p = 0.19).

Conclusion: Among MDR isolates in Chongqing China, Beijing genotype is more likely to be drug resistant and clustered, and SM-resistant isolates are more likely to be clustered that may related to the MDR epidemic. Although 24-loci had a high resolution of genotype, some new loci should be found to replace the poor diversity loci in 24-loci and additional analysis of specific sublineage of Beijing genotype is needed in order to better understand the relations between the molecular characteristics of strains and MDR-TB epidemic.

Abstract
Background:Brucellosis is one of the most widespread zoonosis worldwide, it is caused by Gram-negative coccobacilli, Brucella spp. In China, 90% of brucellosis occurred in six northern agricultural provinces. However, there is an increasing trend of human brucellosis in southern provinces but only limited cases were reported. Our study aims to describe the clinical features and epidemiology of brucellosis in a tertiary hospital of southern china. Methods:A retrospective study was conducted in the past 4 years. Clinical details of brucellosis including occupation, suspected transmission route and complications were retrieved. Serum for tube agglutination test to check Brucella antibody. Blood and aspirate were collected for culture, Vitek 2 and MALDL-TOF MS were used for identification.Results:Thirteen cases of laboratory confirmed brucellosis were encountered in a highly cosmopolitan city Shenzhen of South China between January 2014 and October 2018. Seven of the thirteen patients were male, with age ranging from 29 to 73 years old. Five patients (38.5%) came from Guangdong province, and eight patients (61.5%) came from other provinces. The commonest route of transmission was handling and consumption of infected placenta from goats. Common presenting symptoms include fever, osteoarticular pain and urinary symptoms. Common physical signs were fever, splenomegaly and lymphadenopathy. The commonest complication was spondylodiscitis/ peripheral joint arthritis (n=4), while exotic complications including abdominal aortitis with pseudoaneurysm, hepatic and spleen abscess, soft tissue abscess, and epididymo-orchitis were also observed in 4 other patients. The most life-threating but rare complication of abdominal aortitis in the elderly could be easily missed due to the nonspecific presenting symptom. Conclusions:In summary, brucellosis is increasingly seen in highly cosmopolitan part of southern China. In addition to tuberculosis, typhoid fever and typhus, brucellosis should be considered in the differential diagnosis of fever of unknown origin in this locality. Presence of extensive atherosclerosis in elderly patient may predispose them to endovascular infection by Brucella species.

Abstract
Background: Thymidine kinase 1 (TK1) is a key enzyme involved in DNA synthesis. The aim is to assess the prognostic significance of serum TK1 protein concentration (STK1p) and its role in monitoring of individual customized therapy in non-small cell lung carcinoma (NSCLC) patients in routine clinical setting.
Methods: A prospective study of 129 NSCLC patients was confirmed by imager, /pathology and treated by radical resection (RR) combined with individual-chemotherapy or individual-chemotherapy alone, in 2010 to 2017. The STK1p was measured using an ECL dot blot assay in sera of patients.
Results: Comparisons between 2-cycle-post-individual-chemotherapy and pre-individual-chemotherapy showed that STK1p was significantly associated with treatment effect (p<0.001), and the STK1p low-group correlated significantly to the early/middle clinical stage, as well as the treatment with RR+ individual-chemotherapy (p < 0.05). A significantly poor overall survival (OS) was found in elevated-risk STK1p vs. low-risk STK1p values (p=0.016), in advantage clinical stage vs. early/middle clinical stage (p=0.004), in SCC patients compare vs. AC patients (p=0.003) and in chemotherapy alone vs. RR combined with individual-chemotherapy (p=0.001). The multivariate analysis showed that STK1p (hazard risk=2.295, p=0.010), and RR combined with individual-chemotherapy (hazard risk=3.04, p=0.0001), were independently survival factors.
Conclusions: STK1p correlates significantly to survival and is an independent multivariate prognostic factor in NSCLC patients. STK1p as a low-cost assay, is a useful tool to combine with imager for a rational approach to increase the efficacy in early detection of tumor in lung cancer screening and assessment of individual adjusted therapy in NSCLC patients.
