The terminological interaction «aggression-aggressiveness» in the philosophical and legal discourse
Authors: Maksym Khrystyna
Published: September 2023

The article conceptualizes the essence of aggression as a philosophical and legal phenomenon and reveals the specifics of the terminological interaction "aggression-aggressiveness". The distinction between the concepts of "aggression" and "aggressiveness" indicates that, on the one hand, not all aggressive actions of the subject are actually based on the aggressiveness of the person as a trait, on the other hand, the aggressiveness of a person does not always manifest itself in clearly aggressive actions. Manifestation or non-manifestation of aggressiveness as a personal trait in certain acts of behavior is always the result of a complex interaction of transsituational and situational factors. It turns out that aggression is organically connected with violence and is its natural basis, just as for human society - social matter, the basis is the natural environment, in particular, living matter, in which aggression is a mandatory attribute, but aggression as a phenomenon is not identical to violence, as living matter and social matter are not identical. It is noted that there are many scientific definitions for the category of "aggression", however, researchers often confuse the concepts of "aggression" and "aggressiveness" (that is, a form of behavior and a personal trait), others are too narrow and do not cover all types and forms of aggressive behavior ( direct and indirect aggression, physical and verbal, active and passive, hostile and instrumental, rational and affective, direct and displaced, constructive and destructive, proactive and reactive, socialized and antisocial, etc.), the third, on the contrary, are too broad and include such actions , which are mostly not considered as aggression. It is concluded that aggression is actions that cause damage or lead to the destruction of animate or inanimate object; direct or indirect use of armed force, attack. Aggressiveness is a relatively stable personality trait, the subject's readiness for aggressive behavior.
Revision of Post-Endoscopic Discectomy: A Review
Authors: ALSHARAF Yusuf , Alsaif Mohamed , Sayed Yakub
Published: September 2023

This review focuses on the recurrence of lumbar disc herniation after percutaneous endoscopic discectomy (PED) and the revision surgery options available for patients who require further treatment. PED is a minimally invasive surgical technique used to treat herniated discs in the lumbar spine. Although PED has many advantages over traditional open decompression and fusion surgery, recurrent herniation is a common complication that can lead to the need for revision surgery. It will provide insights into strategies for minimizing complications and improving outcomes of post-endoscopic revision discectomy. The goal is to assist clinicians in selecting the most appropriate revision surgery option for their patients based on individual risk factors and other relevant factors. Ultimately, the review aimed to improve patient outcomes and reduce the need for repeat surgery in cases of recurrent herniation following PED. Various surgical techniques have been described for revision procedures, including repeated endoscopic discectomy, open discectomy, minimally invasive microdiscectomy, and fusion. The choice of technique depends on the specific indications and individual patient characteristics. The review will discuss common options for revision surgery, including minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), micro-endoscopic discectomy (MED), and PED. Factors that increase the risk of recurrence after primary PED surgery, such as advanced age, obesity, and Modic changes, will also be discussed. Further research and long-term follow-up studies are warranted to enhance our understanding of the optimal management strategies and outcomes of post-endoscopic discectomy revision.

Published: September 2023

Sorghum contains a high level of tannins and is known to be anti-nutritional and give rise to an astringent flavour, so polishing is needed. This study aimed to characterize local light-brown waxy sorghum from Lamongan due to varying levels of polishing. An experimental procedure with five replications was used. The results showed that the weight of 1000 grains, seed volume, bulk density, and true density one-time polishing was 20.3109±0.3606 g, 0.016±0.000 ml, 0.755±0.015 g/ml, and 1.70±0.02 g/ml, respectively, whereas the two-time polishing was 12.6072±0.6172 g, 0.010±0.000 ml, 0.843±0,011 g/ml, and 1.67±0,02 g/ml, respectively. The sorghum seed size after one-time polishing was length 4.64±0,23 mm, width 2.98±0,17 mm, height 2.38±0,08 mm, and sphericity 69.04%, whereas after two-time polishing it was 2.90±0.12 mm, 2.89±0.09 mm, 1.84±0.11 mm, and 85.82%, respectively. More polishing resulted in a decrease in 1000 seed weight, hardness, volume, porosity, and true density of sorghum. The results also revealed that sorghum was red after one-time polishing and yellow-red after two-time polishing. Tannin content was 8971.59±42.87 mg/L and 915.88±11.64 mg/L, respectively for one-time and two-time polishing. Light-brown waxy sorghum from Lamongan should be polished two-time to be developed into flour and instant sorghum rice. Keywords: Lamongan, Light-Brown Waxy Sorghum, Polishing, Physical characteristics, Tannins

Purwoceng (Pimpinella pruatjan) is Indonesia’s native herbs that grow in the highlands but its existence is hard to find. The reason is that purwoceng is difficult to cultivate. A controlled factor in cultivation, such as hydroponic types and nutrient concentration, can be used as a solution to this problem. Hydroponic types and nutrient concentration treatments can affect the secondary metabolites and antioxidant activity of the purwoceng root extract produced. This study aimed to determine total phenolic and flavonoid content, as well as antioxidant activity in three different hydroponic systems (nonrecirculating drip, recirculating drip, and nutrient film technique (NFT)) and two nutrient concentrations (1.5‰ and 2.0‰). The combination of recirculating drip with low nutrient concentration was the best treatment to produce an extract with high phenolic and flavonoid content. Purwoceng root extracts from nonrecirculating with high nutrient concentrations produced high antioxidant activity. The characteristics of extracts from recirculating with low nutrient concentrations were similar to those from the nonrecirculating drip. In contrast, extracts from recirculating with high nutrient concentrations were closer to extracts from NFT, proven by principal component and heat map analysis. Antioxidant activity related to total phenolic content, also the presence of betaine and bergapten in purwoceng root extracts. Keywords: Flavonoid content, NFT, Nonrecirculating drip, Phenolic content, Recirculating drip

This study obtained the K factor was in the range 0.12 to 0.22 for Wischmeir-Smith, 0.29 to 0.33 for EPIC, 10–3 to 3×10–4 for M-USLE, and 2×10–4 to 0.1 for WEPP. Based on literature (similar study and site, or soil type approach), the K factor obtained from Wischmeier-Smith method was in the range of reference. While other methods, the K factor was higher or lower than benchmark value.  The proposed method in this study could be applied to calculate K factors of soil. However, the M-USLE and WEPP methods still have shortcomings in the simulation process of erosion and surface run off rates to obtain the K factor.  Keywords: Agrotourism, Drone, Land use, Soil erosion

This study aimed to determine the effect of Growmore and BAP concentrations on the growth of orchid plantlets. The experiment consisted of two factors namely Growmore concentration (0; 3; 6; 9 ppm), and BAP concentrations (0; 1; 3; 5 ppm). The factors combination on ½ MS media was repeated 3 times and obtained 48 experimental units. Observation parameters included the percentage of live plantlets, number of roots, number of leaves, plant height (cm), and wet weight of plantlets (g). Results showed that a Growmore concentration of 3 ppm had a significant effect on the number of roots and plant height at 4.36 units and 4.17 cm. BAP concentration of 3 ppm also had a significant effect on the number of roots, plant height, and wet weight of respectively 4.72 units, 3.22 cm, and 0.63 g. A combination of Growmore 3 ppm + BAP 0 ppm produced the largest percentage of live planets at 100% and plant height at 7.37 cm, Growmore 9 ppm + BAP 0 ppm produced the largest number of roots at 6.33 units and Growmore 6 ppm + BAP 3 ppm produced the largest number of leaves at 8.78 strands.  Keywords: BAP, Dendrobium bigiante, Growmore.

This study aimed to determine the effect of micro-nanobubble generator (MNBG) aeration on the cultivation of spinach (Amaranthus viridis) and pakchoi (Brassica rapa chinensis) hydroponic wicks. The basic principle of this system is that the axis capillary action flows nutrients to the planting medium. There are no moving parts so the nutrients can settle rapidly and the dissolved oxygen content is limited. Micro-nanobubbles (MNB) have the characteristics of a long residence time in the water so that their generation can operate intermittenttly. This study aims to determine the effect of applying (MNBG) with a flow rate of 0.98 L/minute on root length, plant height, and wet weight of spinach and pakchoi plants in wick hydroponics. Cultivation was hold on a free environment. There are three kinds of treatment; without aeration (N0), aeration 15 minutes x 4 for 24 hours (N15), and aeration 30 minutes x 4 for 24 hours (N30). Variations in the types of materials used in this study were spinach and pakchoi, as per treatment was repeat five samples. The study used a Randomized Block Design (RBD). The measurement results compared by the One-Way ANOVA test (5% level), then continued with Duncan's test to determine the difference. The results showed that there was an effect of applying intermittentt MNBG aeration on the average weight and height of the spinach plants, N15 treatment was more effective than the N0 and N30. Intermittentt MNBG aeration did not show a significant difference in the average weight of pakchoi. Keywords:   Aeration, Hydroponics, Spinach, Pakchoi, wick

Soybean is one of the main needs and sources of vegetable protein for Indonesian. National needs of  soybean continue to increase in line with the increase of population, but soybean production has not been able to meet national needs. Therefore, efforts need to be made to increase soybean production by utilizing marginal land with using arbuscular mycorrhizal fungi and biochar. The aim of this study was to determine the effect of single factors of arbuscular mycorrhizal fungi (AMF), biochar and interaction of these two factors on the growth and yield of soybean in Ultisol soil. This research was conducted from  December until March 2019. The research used 3 x 3 factorial completely randomized design with three replications. The first factor was AMF dosage consist of 3 levels : M0 (0 g per plant), M1 (15 g per plant), M2 (30 g per plant) and the second factor was type of biochar consist of 3 levels : B0 (without biochar), B1 (biochar of rice husk), B2 (biochar of coconut shell). The observation data that obtained were analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at level 5%. The results showed that the treatment of AMF improved all growth and yield parameters and the single biochar can not improve all growth and yield parameters. The interaction between AMF and biochar did not improve all parameters of growth and yield of  soybean.
