El uso de la tecnología ha promovido la expansión digital y el crecimiento de herramientas que hacen posible la cuantificación, medición y análisis de los datos. También ha permitido que tecnologías como la inteligencia artificial desarrollen algoritmos y modelos para que las computadoras aprendan y mejoren sus procesos por medio de la experiencia. En este contexto, el machine learning se ha convertido en un aliado en el control de enfermedades crónicas como la hipertensión arterial (hta), que causa el 63 % de las muertes de personas de tercera edad, debido a falencias en adherencia a tratamientos y a los estilos de vida de los pacientes. En este artículo se propone que implementar esta tecnología en el seguimiento del tratamiento de la hta podrá suministrar pronósticos de la condición futura del paciente y evidenciar el avance o la necesidad de un nuevo diagnóstico para mejorar su calidad de vida
Planeación local para la construcción de paz en Sumapaz. El camino desde los planes marco, nacional, distrital y local en Bogotá
Authors: Rojas Muñoz Nadia
Published: June 2023

Una de las mayores dificultades tras la firma del Acuerdo Final para la Terminación del Conflicto Armado que se firmó entre el gobierno nacional y la guerrilla de las FARC es su implementación, es decir, lograr que las políticas se conviertan en planes con presupuesto y en proyectos que sean evidentes para la ciudadanía. En este artículo se tienen en cuenta instrumentos de planeación tradicionales existentes en Colombia, como los planes nacionales, distritales y locales de desarrollo; y los creados tras la firma del acuerdo de paz, como el plan marco de implementación y los documentos Conpes. Estos instrumentos se analizan con los conceptos de desarrollo territorial y de construcción de paz. Además, se revisa el SECOP II de la Alcaldía de Sumapaz entre febrero y junio de 2021. Con lo anterior se evidencian los retos en tiempos desde la creación de la política (acuerdo de paz) hasta su implementación en proyectos concretos en la localidad de Sumapaz.
Rape-By-Deception in China: A Messy But Pragmatically Desirable Criminal Law
Authors: Chen Jianlin , Lu Bijuan
Published: June 2023

China’s Criminal Law defines rape to include circumstances where a perpetrator “by violence, coercion, or any other means rapes a woman.” We critically investigate whether and how this provision is applicable to the use of deception to obtain sexual intercourse, and make three contributions. First, through a quantitative and qualitative analysis of contemporaneous scholarly commentary and a systematic survey of court judgments from 2015 to 2020, we demonstrate that religious fraudulent sex, medical fraudulent sex, and impersonation of intimate partners are punished as rape in China. Second, we argue that the current Chinese law is normatively desirable vis-à-vis the general consensus among scholarly commentary and legal practices elsewhere. Third, we highlight the unique starting point of Chinese sexual offenses provisions as compared to both common law and civil law jurisdictions, and explain how this “blank slate” contributed to a legal evolution process that prioritizes attaining desired legal outcomes at the expense of neat, coherent principles. More broadly, our case study of China challenges the prevailing assumption in English-language literature that civil law jurisdictions are less receptive towards fraudulent sex criminalization. It also cautions against the practice of reviewing statutory provisions in isolation when determining the substantive law of civil law jurisdictions.

Innovation from scrap materials can go beyond expectations. For this reason, the objective of this study is to create a motorized whiteboard eraser out of a car windshield rubber blade from a broken car. With the help of Arduino Uno and Arduino Interface, an open-source electronics platform based on easy-to-use hardware and software, was able to help read the coding and inputs in causing the wiper move with a switch, battery and motor. The results of the study showed that the time of executing the command was 0.35 seconds after turning the switch on, while the distance covered in centimeters by the motorized whiteboard eraser was 75cm. It is also noted that after four rounds of horizontal swiping directions it had totally erased the writings on the whiteboard. Further, in terms of the speed of erasing the writings, the shortest time was 0.0852 miles per hour. Proving its efficacy on erasing various percentages of shaded parts it is recorded that in 50% shaded part it took a minute and six seconds, while in 75% shaded part it took one minute and 20 seconds, lastly, in a 100% shaded it could totally be erased in a span of one minute and 36 seconds. As a result, it is recommended to increase the speed of the motorized whiteboard eraser by utilizing a bigger motor with a higher RPM capacity. Moreover, it is advised that the whiteboard eraser be improved in order for the rubber blade to entirely adhere itself to the whiteboard in order to have less constraints on erasing. It is also recommended that you choose a lighter material than PVC in order for the eraser to operate smoothly.

Improper disposal of waste is a rampant problem that contributes to pollution. The objective of the study is to create an automatic waste segregator bin to be used by the households utilizing proximity sensors. Papers, plastics, and metals are the common wastes at home. Using proximity sensors such as inductive, and capacitive sensors, and with the help of motors the machine can automatically segregate the papers, plastics, and metals into their correct bins. The researchers created the whole setup of the motors and sensors using wood, pipe, screws, and nails to be able to create a functional segregator machine. Proving its effectiveness, testing procedures were conducted in detecting and segregating papers, plastics, and metals, then each was tested based on its maximum weight capacity, the detection time, and lastly, the success rate of being able to detect different types of wastes were tested. The results showed that the segregator has a success rate to detect 100% of metals accurately, 100% of papers, and 100% of plastics. The segregator bin has a maximum weight of 0.6 kg and an average detection time of 1.73 seconds. Through the different testing procedures, the researchers found that it is feasible to create an automated segregator bin using proximity sensors which is also a smart recycling bin as it was able to accurately detect papers, plastics, and metals. Although the researchers were able to attain the desired results, future researchers are still recommended to modify, innovate, and improve the automated waste segregator bin.

Unlicensed Gold Mining (PETI), was found in 4 districts in West Sumatra including, Dharmasraya covering an area of 1,773 ha, Solok 1,533 ha, Solok Selatan 2,559 ha, and Sijunjung 1,103 ha. PETI is a traditional gold mining activity, the results are processed using the amalgamation method. The amalgamation process in the PETI activity will result in environmental degradation caused by the washing process carried out in the river and the process of refining gold ore by burning which produces mercury vapor (Hg) which evaporates in the air. The amalgamation process can cause negative impacts in the form of environmental pollution by mercury vapor as a result of the process. As much as 10 - 30% of the mercury used in the gold amalgamation process will be released into the environment. The main health problems caused by mercury vapor occur in the brain, lungs, central nervous system and kidneys. The purpose of this study was to describe the level of toxicity that occurs in humans through nails on illegal gold miners in Nagari Koto Tuo Sijunjung, West Sumatra. The benefit of the research is as information that is conveyed to local governments and people who are exposed to heavy metals for the dangers they face. The research method is an observational study with a cross sectional study design, which is a study in which the variables including risk factors and variables including effects are observed simultaneously at the same time. The number of samples used in this study were 13 people. Samples were taken using accidental sampling technique.

The problem of domestic solid waste has become a national issue, including in Dumai City, as seen in the Landfill (TPA) in Dumai City (Mekar Sari Landfill, South Dumai District). Many and easy domestic solid waste are found in the landfill, which is caused by not being able to be handled considering that 3 sanitary landfills are full and limited human resources, land and tools. This study aims to determine the implementation and constraints, environmental, social and economic impacts of domestic solid waste management in West Dumai District and South Dumai District. The research was conducted in several stages, starting from an initial survey based on field observations and interviews using variables of waste types and sources in West Dumai District and South Dumai District, the volume of waste, the impact on the environment, social and economic, the form of management implementation, and the constraints possessed in the management. This study used non-probability sampling with snowball sampling method in sampling techniques. This method is used in connection with the collection of interview-based information/data, and multilevel questionnaires, ranging from waste producers, management officers to supervisors of domestic waste management in West Dumai District and South Dumai District of Dumai City. Based on the results of the study, domestic solid waste in West Dumai and South Dumai Districts of Dumai City will continue to increase along with the higher volume of waste produced compared to what can be handled by managers (60%) while the obstacles they have cannot be resolved. Suboptimal management of domestic solid waste has a negative impact on the environment in West Dumai and South Dumai Districts. Among them are triggering easy flooding when it rains, to contamination of water sources used by humans. From a social aspect, the comfort of Dumai residents is disturbed, including their daily activities. From an economic point of view, flooding has an impact on income levels (economic aspects). Flooding (tidal) is increasingly routine in West Dumai and South Dumai Districts with an increasingly tight frequency, namely 2 times / month, which is caused by the topography of the area (lower than other areas) and clogged waterways due to garbage carried by the water flow. The suggestion in this study is to propose management collaboration with companies operating in Dumai in supporting the operation of the 3R TPS, such as financing for operators, providing machines, or for facility maintenance.

In this study, we aimed to show the results of exchange nail and decortication in patients whose subtrochanteric femur fractures were treated with intramedullary nails and subsequently developed fracture nonunion and nail breakage com- plications. This study consisted of patients presenting with subtrochanteric femur fractures between January 2013 and April 2019 who underwent surgery and later experienced nail breakage due to hypertrophic nonunion. There were a total of 10 patients aged 26-62 years (Avg 40,30, SD: 9,989). Nine patients were smokers, and 1 patient had diabetes and hypertension. Three patients were admitted to the trauma center due to a car accident and 7 patients were admitted because of a fall. The infection parameters of all patients were normal. All patients had pathological movement complications and pain at the fracture site. Preoperatively, medulla diameter was measured with standard radiography in all patients. The diameters of the old nails applied to the patients ranged from 10 to 12 mm, and the diameters of the newly applied nails ranged from 14 to 16 mm. The fracture lines of all patients were opened to remove the broken nails, and decortication was performed. No additional autograft or allograft was applied to any patient. Union was achieved in all patients. We conclude that the use of larger diameter nails in conjunction with decortication will prevent nail breakage, improve healing and provide early union in patients with subtrochanteric femur fractures with hypertrophic pseudoarthrosis.

Published: June 2023

Ankle sprain (AS) is the most common sports injury that can be complicated by chronic joint instability. The aim of this study was to examine the relationship between foot types and the ankle sprain events suffered during the sport career in female volleyball players. In this retrospective study, we randomly selected 98 female volleyball players competing in several divisions. Data were obtained from self-administered questionnaires in which the athlete noted data about volleyball practice, whether they had had ankle sprains and the number of these events. Plantar footprint was photographed by a plantoscope classifying each foot as normal, flat or cavus (196 feet). Of the 196 feet, 145 (74.0%) were normal, 8 (4.1%) were flat 43 and (21.9%) were cavus. Thirthy-five athletes reported at least one AS during volleyball practice. In total 65 sprain injuries were reported (35 to the right side and 30 to the left side). In 22 ankles (14 right, 8 left) sprain reinjure (AS ?1) have been reported. A higher AS reinjury rate is correlated to the cavus footprint pattern (p = 0,005). Cavus foot associates to a higher risk of reinjury for ankle sprains in female volleyball players. Knowing the athletes which are more likely to sustain a reinjure may be helpful for the orthopedic surgeon to plan preventive strategies.

Published: June 2023

Tibial eminentia fractures are avulsion fractures of the anterior cruciate ligament caused with additional injuries like meniscus tears or ligamentous injuries. Arthroscopic assisted internal fixation has become a preferred technique with the development of arthroscopic techniques. We aimed to present our results for arthroscopic assisted double tibial tunnel fixation in patients with displaced eminentia fracture. Twenty patients who were operated on for eminentia fracture between January 2010 and May 2014 were included in this study. All fractures were type II according to Meyers’s classification. Eminentia was reduced with two nonabsorbable sutures through the ACL. Two tibial tunnels were created over the medial proximal tibia with a 2.4 mm cannulated drill. The two suture ends taken out of the 2 tibial tunnels were connected on the bone bridge between the tunnels. Patients were evaluated with Lysholm score, Tegner score, IKDC score and examined for clinical and radiological evidence of bony union. Quadriceps exercises were started on the third day. The patients were followed up with a locked knee brace in extension for 3 weeks after surgery and later patients were encouraged to mobilize as pain allowed. The preoperative Lysholm score was 75 ±3.3 and the postoperative Lysholm score was 94.5 ±3. Tegner score was 3.52±1.02 preoperatively and 6.84±1.099 postoperatively. International Knee Documentation Committee(IKDC) score was abnormal in all of the 20 patients preoperatively but normal postoperatively. The postoperative scores of the patients were statistically significant when compared with preoperative activity scores(p<0,0001). Tibial eminentia fractures may lead to pain, knee instability, malunion, laxity, or extension deficit. The technique we have described together with early rehabilitation may give good clinical results.

Previous literature has reported changes in the length or thickness of the patellar tendon (PT) following primary total knee arthroplasty (TKA). This study aims to determine the structural changes in both the length and thickness of the PT after primary TKA using ultrasound (US) and to investigate the association between these changes and clinical outcomes after a minimum follow-up of 48 months. This prospective study used the US on 60 knees of 32 patients (aged 54-80, mean 64.8±7 years) before and after primary TKA to evaluate changes in both the length and thickness of the patellar tendon. Clinical outcomes were assessed with HSS and Kujala scores. At the latest follow-up evaluation, there was a significant overall shortening of PT by 9.1% (p<0.001), in addition to significant global thickening by 20% (p<0.001). Besides, there was significant thickening by 30% in the proximal 1/3 (p<0.01) and 27% in the middle 1/3 (p<0.01) segments of PT. There was a significant negative correlation between the thickening identified in all three parts of the tendon and both clinical outcome measures (p<0.05). The results show the presence significant changes in PT in terms of length and thickness after primary TKA; in addition, increased thickness in PT was more strongly and significantly associated with inferior clinical outcomes, including functionality and anterior knee pain, than shortness in PT. This study also suggests that the US is a viable, non-invasive method for documenting PT changes in both length and thickness after TKA with serial scans.

Published: June 2023

The development of solar powered water treatment technologies had gained a lot of attention in the past decade with applications ranging from treatment of saline water for desalination purposes to treatment of wastewater. It is important to distinguish here between hybrid systems in-which an existing water treatment technology is coupled with an existing renewable energy technology, and other approaches in-which renewable energy such as solar energy is directly used for the treatment of water. An example of the latter is direct solar membrane distillation. In this seminar we will explore direct solar water treatment research with emphasis on solar membrane distillation. This will include recent findings in the field in addition to research gaps and future perspectives.

As a result of this study, the average of career identity and nursing professional self-concept on a four-point scale were 2.52 points and 3.19 points, respectively, and the clinical performance ability and clinical practice satisfaction on a five-point scale were 4.0 and 3.81 points, respectively. The factors affecting the subject's career identity are professional self-concept (β=.34, p<.001), selection motives (β=.27, p<.001), major satisfaction (β=.22, p<.001), clinical practice satisfaction (β=.21, p<.001), and these variables showed 56% explanatory power for career identity. In conclusion, this study suggested that grade-specific major adaptation programs and theory and practice education-linked nursing education programs that can improve nursing professional self-concept, major and clinical practice satisfaction are needed to establish a career identity of nursing students. In addition, it is suggested that each university needs to strengthen career experience programs so that high school students can choose a nursing department in consideration of their correct understanding and aptitude for nursing major.

Günümüzde fosil yakıt kökenli üretim yollarının kaynakları gittikçe tükenmekte ve çevre kirliliğine neden olmaktadır. Fosil kaynakların sınırlı olması, bizi yenilenebilir enerji kaynaklarına yöneltmektedir. Yenilebilir enerji kaynakları ile yapılan üretim ise değişen küresel iklim şartları problemini beraberinde getirmektedir. Güneş ve rüzgâr gibi yenilenebilir enerji kaynakları gün içerisinde farklı üretim değerlerine sahip oldukları için dalgalanan talebe hızlı ve güvenilir yanıt verememektedir. Bu da enerjiden daha verimli ve sürekli faydalanmak adına enerjinin depolanması konusunu beraberinde getirmektedir. Bu makalede 2 farklı güç değerlerindeki Enerji Depolama Sisteminin(EDS) güç sistemi kararlılığı üzerindeki etkileri ayrı ayrı incelenmiştir. Analiz için IEEE 14 baralı güç sistemi kullanılarak 2 farklı güçte enerji depolama sistemi, güneş ve rüzgar üretim birimleri entegre edilen test sistemleri oluşturulmuştur. Düşük ve yüksek güçteki depolama sistemleri ve yenilenebilir enerji kaynaklarıyla birlikte oluşturulan senaryolarda güç sistemlerinde yaşanması olası bir arıza oluşturularak bu arıza karşısında sistemin verdiği tepkiler incelenmiştir. Simülasyonlar Matlab programında; Hadi Saadat’ın kararlılık analizi için temel kabul edilen programı üzerinden geliştirilerek tasarlanan Enerji Depolama Sistemi üzerinden gerçek zamanlı üretim değerleri kullanılarak rotor açı, frekans ve gerilim kararlılığı analizleri gerçekleştirilmiştir. Enerji depolama sisteminin gücünün arttırılmasıyla sistemin arıza karşısında kararlı kalma süresinin düşük güçteki depolama sistemine göre genel olarak arttığı gözlemlenmiştir.

Graph structure is widely used to describe problems in different fields. Problems in many areas, such as security and transportation, are among them. The problems can be solved using approaches similar to the graph structure. The independent set problem, which is NP-Complete problem, is one of the main problems of graph theory and is used in modeling many problems. The implementation of the Independent set problem with the most significant possible number of nodes in the graph is called the Maximum Independent set. A lot of algorithm approach are proposed to solve the problem. This study proposes an effective approach for the maximum independent problem. This approach occurs two steps: computing the Malatya centrality value and determining the maximum independent set. In the first step, centrality values are computed for the nodes forming the graph structure using the Malatya algorithm. The Malatya centrality value of the nodes in any graph is the sum of the ratios of the node's degree to the neighboring nodes' degrees. The second step is to determine the nodes to be selected for the maximum independent set problem. Here, the node with the minimum Malatya centrality value is selected and added to the independent set. Then, the edges of this node, its adjacent nodes, and the edges of adjacent nodes are subtracted from the graph. By repeating the new graph structure calculations, all vertexes are deleted so that the maximum independent set is determined. It is observed on the sample graph that the proposed approach provides an effecient solution for the maximum independent set. Successful test results and analyzes denonstrate the effectiveness of the proposed approach.
Calculating the Centrality Values According to the Strengths of Entities Relative to their Neighbours and Designing a New Algorithm for the Solution of the Minimal Dominating Set Problem

The dominating set problem in graph theory is an NP-complete problem for an arbitrary graph. There are many approximation-based studies in the literature to solve the dominating set problems for a given graph. Some of them are exact algorithms with exponential time complexities and some of them are based on approximation without robustness with respect to obtained solutions. In this study, the Malatya centrality value was used and a new Malatya centrality value was defined to solve the dominating set problem for a given graph. The improved algorithms have polynomial time and space complexities.
Managing Terminal and Transport Processes with Access Management Services
Authors: Jacobsson Stefan
Published: June 2023

Given the massive flows of containers that mega vessels deliver to seaport freight terminals, the terminal and transport operators face major accessibility and congestion challenges. To address those challenges, five information services, named as access management services, are identified that can mobilize interorganizational information flows to achieve effective terminal and transport processes. In those processes, previous research has examined the effects of such services only in the access phase, that is, when containers are loaded and/or unloaded, leaving out the potential effects in the pre- and post-access phases. Consequently, the purpose is to clarify how the five identified access management services can affect activities and resources for all three access phases in the terminal and transport processes. Two empirical studies were performed: a prestudy, which involved 30 observations to identify terminal and transport processes in a seaport terminal, and an improvement study, which involved eight interviews and four focus groups to explain how the processes can be managed effectively. Access management services that can exchange information in real time can perform and utilize the activities and resources in all three access phases effectively. Namely, with the services, effective loading and unloading require fewer movements, drivers, administrators, controllers and less container lifting.

Este trabalho parte da perspectiva de que sociedades alternativas, neste caso uma comunidade costeira na periferia do sistema hegemônico, especificamente na RESEX Mocapajuba, município de São Caetano de Odivelas, costa paraense, constrói seu modo de vida a partir do afeto, particularmente entretecido na relação com a natureza e escolhe permanecer desenvolvendo seu modo de vida particular, distanciando-se da sociedade maior. A pesquisa fez uso de uma etnografia marcada pela condição de ser afetado, portanto, decorrente das próprias trajetórias pessoais do etnógrafo. Ela apresenta uma descrição teórica por meio da alteridade e de concepções decoloniais, compreendendo quais são os motivos que levam os moradores da comunidade de Monte Alegre da Barreta, a fazer escolhas que os conduzem a um modo de vida que se diferencia e se opõe à sociedade hegemônica.

Published: June 2023

It is commonly known that Indonesians speak their mother tongue along with the national language, as well as foreign languages, when interacting with one another in society. The ethnic diversity, cultural diversity, and linguistic diversity of Indonesia help to create multilingual languages. The purpose of this study was to determine the structure and purpose of the English-Indonesian code mixing used by Sandiaga Uno in a speech video on YouTube. This study used a descriptive qualitative method that was based on Creswell's theory and applied Sugiono's documentation-based approach to data collection. While the Miles and Huberman theory, which included data reduction, data display, and conclusion/verification, is used for data analysis. This study shows the many kinds and purposes of code mixing for each statement that Sandia Uno has uttered, including code mixing of words, phrases, hybrids, word reduplication, idioms, and clauses. The study finds a few advantageous uses for code mixing in sandiaga uno. They are: the motivation to experience need, providing additional information, and expressing one's emotions.

The use of mobile phones should be able to make a positive contribution to its users, while increasing reading habits. We believe that it is very important for users to find information on several non-fiction books related to their needs and desires as well as developing a high-potential platform business model. This paper aims to map the relationship between user experience in exploring and reading nonfiction books using mobile phones. The study is a human center and a qualitative approach, which will carry out an analysis of the surveys distributed and user experience obtained from the interview results. Based on the data obtained, not everyone uses mobile phones to read nonfiction, because there are those who rarely read nonfiction using mobile phones and prefer to use books, but based on their experience reading nonfiction via mobile phones is very helpful and practical. The internet is also a supporting factor in nonfiction browsers via mobile phones.
