Purpose: To investigate the effect of metabolic syndrome (MetS) on the response to medicaltherapy of benign prostatic hyperplasia (BPH) after a 3-month period of treatment. Materials and Methods: This was a cohort study of 100 patients, 47 with MetS and 53without MetS, referred to either the primary care unit or referral hospital with BPHwho had moderate lower urinary tract symptoms of prostate involvement and were candidatesfor medical treatment. Our main outcome was response to medical treatmentwith prazosin 1 mg twice a day and finasteride 5 mg daily in patients with BPH on thebasis of International Prostate Symptom Score (IPSS). Multivariate analysis of covariancewas used to compare BPH treatment response in patients with and withoutMetS before and after receiving treatment. Results: The mean volume of the prostate was significantly higher in MetS patientsthan in patients without MetS (57±32.65 mL compared with 46.00±20.19 mL, p=0.036). The control group demonstrated an 11-unit reduction in IPSS, whereas those with MetSshowed a reduction in the symptom score of only 6 units (p<0.001). Regarding the componentsof MetS separately, triglyceride (p<0.001), fasting blood sugar (p=0.001), andwaist circumference (p=0.028) significantly affected the clinical progression of BPH. The observational nature of this study may be a limitation in comparison with an interventionalstudy. Conclusions: The results of the present study showed that MetS can negatively affectthe response to medical treatment of BPH. Therefore, it is necessary to consider MetSin selecting patients with BPH for drug therapy.

Purpose Overturning and high vibration levels are major causes of agricultural farm fatalities and mechanical troubles during operation. This study assessed the stability angles of a self-propelled 1-row Chinese cabbage harvester and measured the vibration levels for safety under different conditions. Methods The stability of the Chinese cabbage harvester was investigated using computational methods, and the vibration levels were measured on off-road and field conditions. The three-dimensional model of the Chinese cabbage harvester was designed and simulated to evaluate the static stability angles employing commercial software. The relationship between vehicle and deformable soil was calculated using the empirical models. The critical angles and the climbing ability of the developed harvester were examined under loaded and unloaded conditions. The vibration exposures were measured on the cabbage conveyor and the power transmission part in static, off-road, and field operation conditions under various speeds and slopes. Results The stability simulation results showed the minimum lateral stability angles of the harvester were pointed on the loaded condition compared to the unloaded condition. The maximum sideways overturning angle of the Chinese cabbage harvester was recorded as 32° at 150° ground angle and 30° at 270° ground angle, from the moving directions clockwise, for unloaded and loaded conditions. The high levels of vibration were measured at 0.19, 1.64, and 1.38 m/s2 for static, off-road, and field conditions at high speeds among X-, Y-, and Z-axis directions, respectively. Besides, the considerable vector sum (Av) exposures were calculated 1.54, 2.14, and 2.48 m/s2 at 0.3, 0.6, and 0.9 m/s forward speeds on the cabbage conveyor part. Conclusion The concept and guidelines of this research could help to protect operators from safety risks and expose vibration characteristics during farm operations of the self-propelled Chinese cabbage harvester prototype.

According to the reports of the World Health Organization 20% of world population suffer from pain and 33% of them suffer to some extent that they cannot live independently. Methods: This is a cross-sectional study which was conducted in the emergency department (ED) of Valiasr Hospital of Arak, Iran, in order to determine the causes of delay in prescription of analgesics and to construct a model for prediction of circumstances that aggravate oligoanalgesia. Data were collected during a period of 7 days. Results: Totally, 952 patients participated in this study. In order to reduce their pain intensity, 392 patients (42%) were treated. Physicians and nurses recorded the intensity of pain for 66.3% and 41.37% of patients, respectively. The mean (SD) of pain intensity according to visual analogue scale (VAS) was 8.7 (1.5) which reached to 4.4 (2.3) thirty minutes after analgesics prescription. Median and mean (SD) of delay time in injection of analgesics after the physician``s order were 60.0 and 45.6 (63.35) minutes, respectively. The linear regression model suggested that when the attending physician was male or intern and patient was from rural areas the delay was longer. Conclusions: We propose further studies about analgesics administration based on medical guidelines in the shortest possible time and also to train physicians and nurses about pain assessment methods and analgesic prescription.

Excessive use of pesticide increase production costs and negatively impact on the environment. Increasing spraying effectiveness is one of the major goals of precision variable rate technologies. The technical performance of the nozzle significantly impacts sprayer performance and quality. Analysis of the effects of operating pressure and boom height on spray dispersal and uniformity was the goal of this research. The test bench consisted of four nozzles (NN D-35) and a single-cylinder motor with a four-stroke capacity of 0.72 kW. This self-propelled sprayer was tasted on the ground with 2 km/h speed. Experiments were conducted both in lab and field condition with conventional spray nozzles and water as the test liquid. Tested liquid outflow pressure ranged from 280 to 520 kPa. Depending on the spraying target surface, 35, 45, and 55 cm of working spray boom height were adjusted. The nozzle spacing was 30 cm and the spray angle of the nozzles was 110o. Resultant sprayer nozzle widths with boom heights of 35, 45, and 55 cm caused overlaps of 22.38%, 23.43%, and 24.15% under the lab condition and 24.11%, 26.32%, and 29.37% under field condition. Under the laboratory condition average droplet density levels of 155.38, 159.20, and 168.31 (spots/cm2) were achieved at boom heights of 35, 45, and 55 cm with a speed of 2 km/h, resulting in the spray coverage levels of 23.21%, 26.38%, and 28.35%, respectively. At boom heights of 35, 45, and 55 cm at a speed of 2 km/h, average droplet densities of 138.62, 151.22, and 171.91 (spots/cm2) were obtained under the field yielding spray coverage levels of 24.11%, 26.38%, and 29.37%, correspondingly. Under the both conditions, the 55 cm boom overlapped less than 30%, and the average droplet density and spray coverage in unit area were better than the other two boom heights. It would also be economical and environmentally friendly to use these spraying tools.

Mohammod Ali,Md Razob Ali,Md Ashrafuzzaman Gulandaz,Md Asrakul Haque,Md Sazzadul Kabir,Sun-Ok Chung 사단법인 한국정밀농업학회 2023 정밀농업과학기술지 Vol.5 No.3

Precision water management is crucial for greenhouse agriculture to maximize crop yields in sandy soil. Due to the low water holding capacity, it is necessary to monitor the water movement in different depths of sandy soil to ensure effective irrigation. Therefore, this study aimed to develop a data acquisition (DAQ) system for sandy soil water content monitoring in an experimental soil bin inside a greenhouse, utilizing the capabilities of the Internet of Things (IoT). A drip irrigation system was implemented, arranged in four pipelines, spaced 60 cm apart, with drippers placed at 30 cm intervals along the pipeline. The overall system was installed in a sandy soil testing bin. A DAQ system was comprised of three basic units: sensor interfacing and circuit board, programming and sensor data acquisition, and data storage and monitoring. A microprocessor was used by interfacing a set of soil water content sensors, ambient temperature, and humidity sensors. The water content sensors were placed in the soil at different depths of 10, 20, 30, 40, and 50 cm, respectively. A microcontroller was used to collect and send the sensor data to monitor and store in memory. During the test, the maximum and minimum average of soil water content, ambient temperature, and humidity values were observed at 33.91±2.5 to 26.95±1.3%, 21.39±2.1 to 42.84±1.7°C, and 48.73±2.3 to 99.90±0.3%, respectively. The water content percentages were varied at different depths of sandy soil due to low water holding capacity. The developed automatic DAQ system would help with remote monitoring and control of greenhouse irrigation, considering the different crop characteristics and environmental conditions.

( Md Razob Ali ),( Samsuzzaman ),( Eliezel Habineza ),( Md Shaha Nur Kabir ),( Mohammod Ali ),( Beom-seon Kang ),( Sun-ok Chung ) 한국농업기계학회 2023 한국농업기계학회 학술발표논문집 Vol.28 No.2

Plastic seedling pots have been widely used due to their light weight and durable nature, but they hinder root establishment efficiency. However, recent studies have demonstrated that biodegradable potted seedlings could improve seedling resilience, while also being eco-friendly through natural decomposition. In this research, a transplanting mechanism for biodegradable potted vegetable seedlings was designed using commercial software, incorporating working speed analysis to enhance smooth collection and plantation of leafy vegetable seedlings. Theoretical analysis of the vegetable transplanting mechanism for biodegradable seedling pots was conducted, including calculations of position, velocity, acceleration, and input driving torque. Additionally, the selection of appropriate link combinations within the mechanism was explored to ensure smooth transplantation of potted seedlings in optimum depths and spacings. The kinematic model of the transplanting mechanism was simulated using commercial mechanical design and simulation software. The transplanter was comprised of a 4-bar mechanism: a driving link, a driven link, a connecting link, and a supporting bar. In order to enable better hopper motion, a spring was affixed between the driven link and the ground. The movement of the mechanism was primarily controlled through a crank-rocker mechanism, where the arm lengths play a crucial role in determining the planting trajectory. The mathematical model analysis and simulation revealed that a forward speed of the transplanter of 300 mm/s and a rotating speed of the dibbling mechanism of 40 rpm were favored of 48 seedlings/min in order to obtain a high degree of seedling uprightness. The simulated velocities and accelerations of the end hopper in ‘X’ and ‘Y’ directions for suitable link combination were found to be 430mm/s,530mm/s,and 975 mm/s2,2091mm/s2,respectively.The required driving torque was observed to be 603N-mm,and the vertical linear displacement of the hopper was 281mm.

Ali Massumi,Kabir Sadeghi,Ehsan Moshtagh 국제구조공학회 2018 Structural Engineering and Mechanics, An Int'l Jou Vol.68 No.3

The real behavior of the RC structures constructed based on the assumed specifications of the used materials is matched with the designed ones when the assumed and the applied specifications in construction are the same. Despite in the construction phase of the reinforced concrete (RC) structures always it is tried to implement the same specifications of materials as given in the executive drawings, but considering the unpredicted/uncontrolled parameters that affect the specification of materials, always there is a deviation between the constructed and the designed materials’ specifications. The objective of this paper is to submit a guideline for the evaluation of the strength and damage to the existing RC structures encountered deviation in materials’ strengths. To achieve this goal, the lateral strength (plastic behaviors) and damage to twenty-five RC moment-resisting frames (MRFs) are studied by applying the inelastic analysis. In this study, a couple of concrete and reinforcement strengths’ deviations are investigated. The obtained results indicate that in general, there is a semi-linear relationship between the deviation in the strength of reinforcement and the changes in the lateral strength values of the MRFs. The relative effect of the deviation in the strength of reinforcements is more than the relative effect of the deviation in the concrete strength on the damage rate. The obtained results could be a guideline for the engineers in the survey of the existing buildings encountered deviation in materials’ strengths during their construction phase.

ALI MOHAMMOD,이예슬,Md. Shaha Nur Kabir,강태경,이상희,정선옥 한국농업기계학회 2019 바이오시스템공학 Vol.44 No.4

Purpose A tractor-mounted cabbage collection system is under development to improve the mechanization rate of dryland crop production. The design of the cabbage-transportation part of a tractor-mounted Chinese cabbage collector is crucial for minimizing cabbage losses and for effective operation. Investigation of the effects of design parameters is useful to provide guidelines to fabricate the mechanism efficiently. Therefore, the present study aimed to conduct kinematic analysis of the cabbagetransportation part for optimum design of the Chinese cabbage collector. Methods The conceptual design of the Chinese cabbage collector mainly consists of the cabbage transportation, packaging, and unloading parts. Kinematic analysis of the cabbage-transportation part was conducted to investigate the effects of link lengths on the position, velocity, and acceleration of the mechanism. The performance of the cabbage-transportation part was simulated using a commercial software. The simulations were carried out using several cabbage sizes, cabbage transfer speeds, and link sizes at different locations on the cabbage-transportation part. The kinematic modeling and analytical procedure of the cabbagetransportation part were analyzed using mathematical models. Results The successful transfer of cabbage through the conveyor belt was influenced by the width of the cabbage-transportation part, cabbage size, and feeding speed. Consequently, some combinations of link lengths were not acceptable to convey the cabbages with the increase in the width of the transportation part. On the contrary, interferences between the links occurred with the decrease in the width of the transportation part. The simulated results showed that greater transferring speeds of cabbage increased the kinematic values, causing damage to the cabbages. The recommended and effective cabbage transferring speed, the length of the link, and the width of the transportation part were found to be 0.2 m/s, 190 to 200 mm, and 500 to 600 mm, respectively. Conclusion This study is useful for the design of an efficient cabbage-transportation part, and suitable improvements to the fabrication of the Chinese cabbage collector prototype.

KABIR MD SAZZADUL,GULANDAZ MD ASHRAFUZZAMAN,ALI MOHAMMOD,레자 나심,사하눌 카빌,정선옥,한광민 충남대학교 농업과학연구소 2024 Korean Journal of Agricultural Science Vol.51 No.1

Yield monitoring systems have become integral to precision agriculture, providing insights into the spatial variability of crop yield and playing an important role in modern harvesting technology. This paper aims to review current research trends in yield monitoring systems, specifically designed for non-grain crops, including cabbages, radishes, potatoes, and tomatoes. A systematic literature survey was conducted to evaluate the performance of various monitoring methods for non-grain crop yields. This study also assesses both mass- and volume-based yield monitoring systems to provide precise evaluations of agricultural productivity. Integrating load cell technology enables precise mass flow rate measurements and cumulative weighing, offering an accurate representation of crop yields, and the incorporation of image-based analysis enhances the overall system accuracy by facilitating volumetric flow rate calculations and refined volume estimations. Mass flow methods, including weighing, force impact, and radiometric approaches, have demonstrated impressive results, with some measurement error levels below 5%. Volume flow methods, including paddle wheel and optical methodologies, yielded error levels below 3%. Signal processing and correction measures also play a crucial role in achieving accurate yield estimations. Moreover, the selection of sensing approach, sensor layout, and mounting significantly influence the performance of monitoring systems for specific crops.
