Authors: Topcuoglu Ethem , Oktaysoy Onur , Erdogan Selen Uygungil , Kaygin Erdogan , Karafakioglu Engin
Published: April 2023

Digital leadership emerges as the reflection of technological innovation in business life into administration mentality. As well as possessing leadership skills, digital leaders can be defined as leaders who are talented in terms of information technologies, visionary, can think innovatively, increase the corporation’s performance and create the transformation required by the business. The literature emphasizes that digital leadership practices and digital transformation efforts can fail due to fear of being unemployed, the tendency to maintain the usual, and showing resistance to transformation. However, it is realized that these approaches are generally based on foresight and are not supported by real practices. In this regard, the mediating effect of job security satisfaction of employees on the impact of digital leadership upon job satisfaction and life satisfaction is tried to be explained with application findings by utilizing from Resource Based View (RBV). The study was conducted with 403 employees working in an industrial organization. The data obtained were analysed through the Smart-PLS program, and the mediating effect was measured using a structural equation model. The model found that digital leadership had a significant effect (0.199) on job satisfaction, digital leadership had a significant effect (0.182) on life satisfaction, and digital leadership had a significant effect of 0.312 on the perception of job security. Once again, it was found that the perception of job security had a partial mediating effect (0.156) on the effect of digital leadership upon job satisfaction, and the perception of job security had a partial mediating effect (0.150) on the effect of digital leadership upon life satisfaction. The present study indicated that in a well-designed digital transformation, digital leaders could increase employees’ job and life satisfaction, and job security had a mediating impact upon this increase. Digital transformation in businesses creates an environment that allows high-performing employees to stand out more than low-performing employees and to display their talents. Thus, it could be stated that digital technologies have a significant effect on the prominence of talented individuals and increase employees’ job satisfaction and life satisfaction by utilizing RBV, as well. As a consequence of its structural characteristics, digital leadership paves the way for more effective use of human resources in the enterprise, the realization of the necessary organizational transformation, and the increase in the perception of job security of the employees thanks to the contribution it provides to the qualitative improvement of the organization.
Moral metaphysics as philosophy of culture in Tu Weiming’s Boston Сonfucianism
Authors: Sukhomlinova Victoria V.
Published: April 2023

New Confucianism is a philosophical movement which seeks to combine Confucian tradition with Western philosophical thoughts. The idea appeared to some extent due to ideological motives. For instance, New Confucian Mou Zongsan formulated the concept of moral metaphysics, which was supposed to compete with Kantian transcendentalism. Moral metaphysics is further developed by Mou Zongsan’s follower Tu Weiming, who belongs to Boston school of New Confucianism. His moral metaphysics is essentially different from that of Mou Zongsan. It is based on the notion of “self-enlightenment” (cheng). It presents an idea that in some cases interpretation can serve as a research method and be more precise than analysis. The focus of investigation is not the way how something first emerged and developed, but how it was examined and interpreted afterwards. In other words, the key to understanding is the “second birth” of things which happens during the interpretation. But to interpret correctly, we should possess the full knowledge of “ourselves”. However, “oneself ” also turns out to be not a separate body subject to analysis, but an aggregation of interpretations offered by others. The drawn conclusion is that everything exists only when it has an opportunity to interpret oneself during interaction. And in this sense “self-enlightenment”, according to Tu Weiming, is a “certain form of metaphysics”. This article, however, suggests narrowing this conclusion to cultural existence. Unlike Mou Zongsan, Tu Weiming does not intend to prove that the Chinese philosophical thinking is better than the Western one. We can view his moral metaphysics as a certain type of philosophy of culture. It does not offer a precise analytical approach, but it does present a certain pattern of thought, which deals with embracing the form of one’s cultural existence.
A novel-tuned Custom ensemble machine learning model to predict abutment scour depth in clear water conditions
Authors: Kumar Lalit , Afzal Mohammad Saud , Ghosh Somshubhra
Published: April 2023

Most bridge failures occur due to the development of scour holes around the abutment and pier. Therefore, accurate prediction of abutment scour depth is critical for designing and maintaining bridges to ensure their safety and longevity. Traditional methods for predicting abutment scour depth, such as empirical formulas and physical models, have accuracy, applicability, and cost limitations. Machine learning (ML), on the other hand, has the potential to overcome these limitations by leveraging large amounts of data and identifying complex patterns and relationships that are difficult to detect using traditional methods. ML models can be trained on various data sources, including field measurements, laboratory experiments, and numerical simulations, to predict abutment scour depth accurately. Therefore, the present study aims to develop a novel-tuned Custom ensemble ML model for predicting abutment scour depth in clear-water conditions. The proposed Custom ensemble model outperforms the ML models used to predict non-dimensional scour depth at abutments with an accuracy of 95.93%.
Prediction of biochemical oxygen demand with genetic algorithm-based support vector regression
Authors: Liu Yan Zheng , Chen Zhiyuan
Published: April 2023

Five-day biochemical oxygen demand (BOD5) is a vital wastewater contamination strength indicator. The process of measuring BOD5 is to measure the mass of molecular oxygen consumed in 1 L of water at 20 °C over a 5-day incubation period. It is a time-consuming process and often too late for water management agencies to make a timely reaction if the result of measurement shows a water body is seriously polluted. Biosensors can simplify the process of BOD5 measurement; however, the measurement results often deviate significantly from the measured BOD5 values. The main aim of this research is to identify a machine learning model, which could predict BOD5 value from historical data and make it easier to detect water pollution in advance and timely adopt treatment measures. Three machine learning techniques, linear regression, support vector regression (SVR) and multi-layer perceptron (MLP) and two optimization processes have been studied in this research. Four main steps, preprocessing (one-time only), model training, model evaluation (testing) and analysis have been implemented in the experiments. With three feature selection strategies, the results of the experiment showed that SVR with genetic algorithm (GA) optimizer achieved the best performance with R2 of 0.694 and the lowest MAE of 0.109.
Park Je-in(朴齊寅)'s Interest in the Commercial Economy Revealed in the 『YeonSa-rok(燕槎錄)』
Authors:   The Association of DaeDong-Hanmun, Lee Gyu-Pil
Published: April 2023

This paper examines Park Je-in's (1818~1884)『YeonSa-rok(燕槎錄)』and examines his interest in the economy contained in them.
Previous studies have dealt with Park Je-in's 『YeonSa-rok(燕槎錄)』 earlier. In previous studies, studies were conducted focusing on Bukhak ideology(北學思想), Madu(馬頭, A state slave), and Cheongsimhwan(淸心丸, A kind of tranquilizer). As a result, the organization and role of national slaves, the status of Madu, and the importance of Cheongsimhwan in diplomacy were identified. In the process, previous studies mentioned the aspect of economic profit in fragments. This is evidence of the following facts. It is that previous studies have also detected that Park Je-in's interest in the economy is contained in the 『YeonSa-rok』.
In this paper, we intensively reviewed the 『YeonSa-rok』 in relation to economic issues. Therefore, it was mainly considered focusing on hotel management strategy, currency economy, and commodity economy. In addition, the hotel's service system, advertising strategy, and branding strategy were highlighted. In addition, aspects such as product management, brand management, price management, reliability management, and customer management were highlighted, including the reality of the monetary economy. The process of all these studies was tried to prove based on specific data.
In short, Park Je-in's 『YeonSa-rok』 is not only a simple 『Yolha-Ilgi(熱河日記)』 type of Yeonhaeng-rok(燕行錄, A record of a diplomatic trip to Beijing) that is faithful to the succession of Bukhak ideology. It shows a very acute interest and problem consciousness in the changes in the market economy of the Qing Dynasty(淸朝) in the 19th century. In addition, it is a work that captures the consciousness and economic activities of the Korean lower class people that change accordingly. I think this point is one of the representative signs of significant difference between the 18th century Yeonhaeng-rok and the 19th century Yeonhaeng-rok.

Актуальність. На сьогодні остаточно не з’ясований взаємозв’язок розвитку діабетичної ретинопатії (ДР) за стадіями та ступеня тяжкості діабетичного макулярного набряку (ДМН) за умов цукрового діабету 2-го типу (ЦД2). Мета роботи: дослідити взаємозв’язок тяжкості діабетичного макулярного набряку, стадії діабетичної ретинопатії та цукрового діабету 2-го типу. Матеріали та методи. Дослідження включало 81 пацієнта (81 око) із ЦД2, у яких за Міжнародною клінічною шкалою тяжкості ДР Американської академії офтальмології (2002 рік) виявлена легка (10 очей, 1-ша група), помірна або тяжка (33 ока, 2-га група) непроліферативна ДР та проліферативна ДР (38 очей, 3-тя група); контрольну групу становили 50 пацієнтів (50 очей) з ЦД2, нормалізованим вуглеводним обміном, ДР 0 (ретинопатія відсутня) та відсутнім ДМН. Усім пацієнтам були виконані загальноприйняті офтальмологічні дослідження, оптична когерентна томографія (ОКТ). ДМН встановлювали при товщині сітківки більше ніж значення нормативної бази даних за полями ETDRS програмного забезпечення спектральнодоменної ОКT. Для статистичних досліджень використано програмні пакети MedStat і MedCalc v. 15.1 (MedCalc Software bvba). Результати. У пацієнтів з ЦД2, які на момент першого звернення по спеціалізовану офтальмологічну допомогу мали ДР і ДМН, був встановлений прямий взаємозв’язок стадії ДР та ступеня тяжкості ДМН (р = 0,043). Ранговий кореляційний аналіз Спірмена показав наявність позитивного зв’язку стадії ДР та ступеня ДМН (r = 0,25; 95% ДІ 0,04–0,45; р = 0,022). При порівнянні пацієнтів за стадіями ДР або за ступенем тяжкості ДМН встановлена відповідність клініко-офтальмологічних показників (віку, внутрішньоочного тиску, вмісту у крові глюкози та глікованого гемоглобіну). Встановлена позитивна залежність тривалості ЦД2 від ступеня тяжкості ДМН (р = 0,021), але не від стадії ДР (р = 0,603). Висновок. Проведене дослідження виявило особливості пацієнтів з ЦД2, ДР та ДМН, які вперше звернулися по спеціалізовану офтальмологічну допомогу.
Деякі аспекти клініки та лікування увеальної глаукоми
Authors: Bezditko P.A. , Bezditko N.V. , Muzhichuk O.P. , Muzhichuk V.O.
Published: April 2023

Глаукома є одним із руйнівних ускладнень увеїту. Загальна поширеність глаукоми в очах з увеїтом коливається від 10 до 20 %. Увеальна глаукома (УГ) визначається в тих випадках, коли у хворого на увеїт є підвищений внутрішньоочний тиск (ВОТ) та пошкодження зорового нерва за глаукомним типом. У розвитку УГ мають місце механізми відкритого та закритого кута. Особливості УГ пов’язані зі змінами продукції та складу камерної вологи та із застосуванням кортикостероїдів. Підвищення рівня простагландинів при увеїті збільшує увеосклеральний відтік, що сприяє гіпотонії ока і призводить до проблем при призначенні гіпотезивної терапії і хірургії УГ. Призначення різних гіпотензивних препаратів у цих випадках може непередбачувано порушити баланс вироблення камерної вологи, шляхів відтоку внутрішньоочної рідини, що може призвести до провалу в гіпотонію ока. Хірургія увеальної глаукоми при активній простагландиновій реакції та активізації увеосклерального відтоку небезпечна через післяопераційну гіпотонію, циліохоріоїдальне відшарування. Терапевтичний підхід до увеальної глаукоми індивідуальний, нерозривно пов’язаний із основною етіологією і включає лікування запалення ока та підвищеного очного тиску. З огля-ду на особливості перебігу увеальної глаукоми, нестабільність очного тиску підбір гіпотензивних препаратів у цих хворих потрібно проводити дуже ретельно, з постійним контролем ВОТ. У випадках, коли антиглаукомні препарати неадекватні (приблизно 25–30 %), розглядаються хірургічні методи лікування.

Published: April 2023

Аміодарон — один із найбільш широко застосовуваних антиаритмічних препаратів. Незважаючи на високу фармакологічну ефективність, аміодарон має широкий спектр ускладнень, як кардіальних, так і екстракардіальних. Аміодароніндуковані дисфункції легень, щитоподібної залози, печінки та інших органів є приводом до відміни препарату. Можливість розвитку офтальмологічних порушень унаслідок використання препарату потребує обов’язкового динамічного спостереження офтальмологом таких пацієнтів.
High-Intensity Ultrasonication as an Innovative Approach for the Softening of Wooden Breast Meat in Broilers

Published: April 2023

Considering the remarkable implications exerted by the occurrence of wooden breast (WB) abnormality on meat tenderness and marketability, the poultry processing industry demands the implementation of postmortem procedures that can improve the textural traits of chicken breasts affected by this defect. Within this scenario, this study aimed at exploring the effectiveness of high-intensity ultrasonication (HIU) in attenuating the toughness of WB fillets and evaluating its effects on the main technological properties and quality characteristics of chicken breast meat. Overall outcomes showed that HIU significantly reduced (P<0.01) the compression forces of both unaffected and WB raw meat without negatively affecting the main meat quality traits and technological properties, such as color and water holding capacity. The significant (P<0.05) increase in myofibrillar fragmentation index (MFI) observed in unaffected fillets might hint at an alteration of myofibril integrity following the mechanical action of ultrasonic waves. However, despite the effectiveness of HIUin improving the textural traits of raw WB meat, overall outcomes obtained through western blot and MFI analyses suggested that HIU did not remarkably alter the microstructure of myopathic muscles. The myodegenerative lesions typically occurring in WB muscles may have partially disguised the mechanical effects of ultrasonic waves on muscle cells’ structures, making the elucidation of the mechanisms that lead to the softening of WB meat particularly complex.

Published: April 2023

Abstract: Handwriting recognition using OCR (Optical Character Recognition) is a transformative technology that is rapidly changing the way we interact with handwritten documents. OCR technology has traditionally been used for scanning printed text, but with advancements in machine learning and computer vision, it is now possible to recognize and digitize handwritten text as well. This has immense practical implications, as it enables handwritten notes, letters, and documents to be easily searchable, editable, and shareable in digital formats[1]. However, despite its potential, handwriting recognition using OCR is still a relatively nascenttechnology and faces several challenges. One of the main challenges is the recognition of handwriting styles that vary widely across individuals and cultures. Another challenge isinterpreting handwriting that is difficult to read, such as cursive writing or handwritten notes withsmudges or crossed out words. Additionally, OCR software is highly dependent on the qualityof the input image, making it important to optimize the lighting and capture settings for accurate results.[2] As OCR technology continues to improve, it hasthe potential to revolutionize the way we interact with handwritten documents and usher in a new era of digital transformation.

Published: April 2023

Abstract: In developing countries where unskilled workers often face challenges in finding suitable employment, this is where recommendation systems come in, as they can help users find information that is specific to their interests. Using the system decision-making and predictions through algorithms trained on available data across multiple domains makes it easy for users to access pertinent information. One area where recommendation systems can have a significant impact is in helping unskilled workers find jobs based on their skills and interests. Although there are many jobs available for skilled professionals, it can be challenging for daily wage workers to find suitable employment due to a lack of information and awareness. Currently, there are no relevant recommendation systems available to help these workers. In this research, we propose a "Job recommendation system for daily paid workers using Machine Learning" that analyzes a worker’s skills and interests to find appropriate job opportunities. To ensure that the system is robust, we consider a wide range of factors when recommending jobs to daily wage workers.

Published: April 2023

Although empirical research has explored the relationship of perceived corporate social responsibility with turnover intention, how the connection develops and the internal mechanism of this link require further exploration. In this study we examined the mediating roles of work meaningfulness
and affective commitment in the relationship between perceived corporate social responsibility and turnover intention. Employees ( = 802) from real estate and manufacturing firms in China completed an online survey. The study model was assessed by structural equation modeling. Results indicated
that a positive perception of corporate social responsibility indirectly and negatively affected employees' turnover intention. The mediating roles of work meaningfulness and affective commitment in the relationship between perceived corporate social responsibility and turnover intention were
supported. This study provides managers with new insights regarding the value of employees' perception of the organization's corporate social responsibility, which can play a significant role as a future employee governance tool.

Published: April 2023

Traditional technologies for building restorative coatings have exhausted their resource and their use does not provide the required economic indicators. Therefore, the issues of finding innovative approaches in repair production remain relevant and require a fundamental approach. (Research purpose) The research purpose is studying the possibilities of using thin metal matrix composites in repair and restoration coatings. (Materials and methods) Used a metal composition based on a metal matrix - nickel, additionally reinforced with boron carbide and zirconium oxide and applied to the working surface of the valve plate of the internal combustion engine. For the first time, the technology of selective laser sintering was used in the formation of thin reducing coatings under conditions of short-pulse laser reflow of powder media. To assess the heat resistance of the analyzed coating, we have developed a method for testing the temperature resistance of valves, simulating the operation of the valve mechanism of an internal combustion engine. Tribological indicators of coatings were studied using modern techniques and instrumentation to study anti-wear properties. (Results and discussion) Confirmed the possibility of practical implementation of restorative coatings based on metal composite compounds. The restorative coatings studied on the surface of the valve plates of internal combustion engines showed an increase in the wear resistance of the interfaces up to 480 percent. Higher temperature resistance and bully resistance of the contacting surfaces were observed under conditions of oil starvation and dry friction. It was revealed that the decrease in the wear resistance of coatings is determined by a decrease in the coefficient of friction due to the action of tribofilms formed as a result of high temperatures in the friction zone and resistant to dynamic and kinematic loading. (Conclusions) The presented research results have high scientific potential and practical significance. Their use will increase the reliability and durability of machine parts in the conditions of repair and machine-building production.

Published: April 2023

Powder additive materials for electrocontact welding are rarely used due to the loss of expensive powder during welding and the difficulty of cooling the welding zone. However, the use of powder materials allows you to obtain a variety of coating properties and increase the adhesion strength of the powder coating to the base metal of the part. (Research purpose) The research purpose is evaluating the effect of the composition of powder on the hardness, adhesion strength and wear resistance of coatings obtained by electrocontact welding. (Materials and methods) Metal powders of the FBH-6-2, PG-C1, PG-C27M, Sormayt, PZHR3.200.28, PR-NH17SR4, PZH1S brands were used. The adhesion strength was determined by the cut-off method on a P-125 brand press. Hardness was evaluated according to the standard Rockwell method on a TC-2 hardness tester; wear resistance was evaluated on a SMC-2 friction machine. (Results and discussion) It was revealed that the greatest adhesion strength to the base metal of the part (steel 45) is observed in the coating of the powder of the PGS-27M brand during electrocontact welding on "hard" modes. The highest hardness was recorded in the coating of "Sormite" powder. The least wear was observed in coatings obtained by electrocontact welding of powder compositions PZHR3.200.28+Sormayt and PZHR3.200.28+VK8. (Conclusions) The use of powder additive materials to obtain coatings on machine parts by electrocontact welding makes it possible to obtain coatings that are superior to coatings obtained by electrocontact welding of steel tapes. The adhesion strength of steel tapes welded by electric contact welding on "soft modes" is about 100-200 millipascals, which is 1.2-1.4 times less than the adhesion strength of powder coatings. The hardness of coatings made of steel tapes and wires reaches HRC 60, and powder coatings up to HRC 65.

Modern trends in the development of electric distribution networks for agro-industrial facilities related to the introduction of more complex production technologies, increased consumer loads and stricter requirements for reliability and energy efficiency of networks are considered. In the conditions of sectoral supply restrictions and the need to replace imported components, the possibilities of implementing the advantages of distributed electric power in flexible energy supply of agro-industrial and social facilities on the basis of domestic technology and innovative methods are presented. (Research purpose) The research purpose is considering the technical support of distributed generation systems and analyzing possible problems that may arise during the integration of distributed generation sources into the electrical system of the agro-industrial complex. (Materials and methods) Used statistical data to analyze the availability of agro-industrial facilities with distributed electric power. (Results and discussion) It has been shown that the agro-industrial complex is dominated by objects that are far removed from the center of the energy system, with electrical equipment that is morally and technically outdated, which affects the reliability of power supply and the quality of electricity. It was determined that the introduction of distributed generation sources requires modernization or updating of the main electrical equipment of distribution points or substations. Alternative technical solutions have been proposed to improve the quality of electricity supplied to consumers and the reliability of power supply systems, focused on the maximum approximation of the power source to the consumer by placing distributed generation sources near the objects of the agro-industrial complex. They gave specific schemes of power supply systems, the results of technical and economic analysis and options for using traditional and renewable sources of electricity. (Conclusions) It was stated that the further development of the agro-industrial complex facilities is associated with an increase in the level of energy supply, reliability, energy efficiency and environmental friendliness of power supply systems through the introduction of modern distributed generation systems based on traditional, renewable and combined sources of electricity.

Ensuring the required voltage level in rural electric grids is a necessary condition for the efficient operation of agricultural enterprises and comfort in rural life. The overstated length of rural power transmission lines leads to excessive voltage deviations at consumer inputs. The existing methods and technical means of voltage regulation do not in all cases allow to provide the necessary level of voltage in the grid. (Research purpose) The research purpose is developing a method and device for phase-by-phase automatic voltage regulation in the electrical grid using linear voltage regulators, to illustrate the possibilities of its application. (Materials and methods) Used general scientific research methods, methods: literary review, theory of automatic control, electrical engineering. We analyzed the literary sources. We have studied the methods and technical means of voltage regulation in electrical grid. (Results and discussion) A new method and device for adaptive automatic voltage regulation in the rural electrical grid with the use of a separate phase-by-phase installation of linear voltage regulators have been proposed. We considered an example of the implementation of the method in a rural electrical grid with an uneven load in phases. (Conclusions) It was revealed during the review of voltage regulation methods that adaptive automatic control methods are promising, involving control of voltage deviation at consumer inputs and determination of the regulation coefficient based on this. It was determined that the use of the proposed method and device provides a normalized voltage value at consumer inputs by means of adaptive automatic phase-by-phase voltage regulation in the electrical grid with separately phase-by-phase linear regulators controlled by an adaptive automatic voltage regulation system that generates control commands based on data processing from voltage sensors installed at control points of the grid, including at consumer inputs.

One of the problems faced by producers in the conditions of slope gardening is the lack of specialized equipment suitable for carrying out the necessary work related to the care of the trunk strips of fruit trees. The design features of the terraces impose restrictions on the operating conditions of agricultural aggregates, among them it is necessary to highlight the possibility of approaching the row line for processing plants from only one side. Most horticultural farms have mainly equipment designed to work in conditions of plain gardening, which is often unsuitable for the care of fruit plantations located on terraces. Research aimed at developing agricultural machinery for processing row spacing and trunk circles of fruit trees in one pass is relevant. (Research purpose) The research purpose is substantiating the main design parameters and operating mode of the mower for mowing vegetation from the space around the stem of the fruit tree without damaging the latter in one pass. (Materials and methods) Used the results of the functioning of technical means in the conditions of mountain gardening through logical analysis. We conducted theoretical studies using the well-known laws of mathematical analysis and theoretical mechanics. (Results and discussion) We examined the operation of the cutting machine of the mower in the process of mowing vegetation in the area of the trunk circle. (Conclusions) A prototype mower was manufactured, production tests of which (at a movement speed of 1.89 kilometers per hour, the number of rotors with cutting segments of 2 pieces, the length of the cutting segment of 42 millimeters, the rotation speed of the rotors of 2000 minutes minus the first degree) confirmed that it with a capacity of 0.36 hectares per hour provides mowing vegetation from the space around the stem of the fruit tree without damaging the latter in one pass. It was determined that due to the creation of a mulching layer, the soil condition is improved, terraces are protected from erosion processes and unit costs are reduced.

Duplication of the ureter and renal pelvis is a relatively common congenital anomaly with an incidence of approximately 1 in 150 births. Different anatomical variations of ureteric duplication exist. Ectopic ureters are usually associated with ureteral duplication and a duplex collecting system. Duplication of the ureter is more common unilaterally, has a female preponderance, and occurs more commonly on the left side. We present the case of a 58-year-old male with inverted Y ureteral duplication who had distal obstructing ureteric calculi in the ectopic distal ureteral opening in the prostatic urethra.

Introduction: Percutaneous nephrolithotomy (PCNL) is the gold standard for treating large or complex renal stones. Renal drainage after the procedure is most commonly via nephrostomy tube or indwelling ureteral stent, but the optimal duration of ureteral stents after PCNL is unknown. This study describes the post-operative events occurring with early stent removal on postoperative day one (POD1) in patients undergoing uncomplicated PCNL.

Methods: We identified 336 patients from a single institution that underwent PCNL between 1/1/2020 and 6/1/2021. Of these, 106 patients with uncomplicated procedures that met inclusion criteria for early stent removal on POD1 were included. In addition, a retrospective chart review was performed to collect demographic information, operative data, and to identify adverse outcomes including additional procedures, patient telephone calls for symptoms, complications and emergency department (ED) visits.

Results: Mean (SD) patient age was 54 (15.1) years and 56% of patients were morbidly obese (Body Mass Index [BMI] > 30). Overall post-operative complication rate was low (18.8%) and limited primarily to Clavien I/II complications with only two Clavien III (1.9%) complications. Telephone calls or electronic messages were received from 37.7% of patients, with 16% requiring a visit to the ED or clinic. The most common reason for an ED visit was flank pain (11.1%).

Conclusions: Early stent removal on POD1 may lead to pain-related telephone calls but appears to be a generally safe and effective management option in carefully selected patients undergoing uncomplicated PCNL.

Coco Island is of volcanic origin with an area of 24 km2, located 530 km
from the Pacific coast of Costa Rica and is the furthest Costa Rican
Island from the continent and with a rainfall of over 7000 mm years-1.
Two types of forest are present, low elevation humid forest and high
elevation cloud forest. This study aims to establish different
distinctiveness of annual rings and dendrochronological potential (DP)
of nine tree species. Any annual ring boundary were not observed in C.
pettieri and H. fascicularis; therefore, they did not present any DP.
Annual ring type 1 (density variation) was presented in A. compressa, H.
succosa, H. odorata, and P. cocosensis, however the annual rings
boundary was more defined in A. compressa and H. succosa than other
species. O. insularis and S. Holdridgei presented annual rings boundary
type 5, fiber band and were adequate distinctiveness. Finally, Eugenia
pacifica presented annual ring type 3 (pattern de fiber/parenchyma) and
type 4 (vessels distribution), but its distinctiveness was limited. Coco
Island´s trees presented seven species with more or less distinctive of
annual ring, but three species (A. compressa, E. pacifica, and P.
cocosensis) presented low DP. Meanwhile H. succosa, H. odorata, O.
insulares, and S. holdridgei showed medium DP. These species growth in
the two types of forest in the island and add to abundance and tree
diameter, these species have some DP and they can be used to establish a
chronology from 50 to 130 years.
