Toko Ritel Accessories adalah sebuah toko ritel yang berlokasi di daerah Kota Cirebon. Toko Ritel Accessories merupakan toko yang menjual berbagai macam barang kelontongan. Dalam penelitian ini menggunakan 624 record data penjualan terhitung dalam kurun waktu 12 bulan. Toko Ritel Accessories memiliki banyak tipe barang sehingga kesulitan dalam melakukan strategi penjualan dan mengelola manajemen penyimpanan. Selain itu Toko Ritel Accessories juga masih kesulitan dalam menentukan barang apa saja yang diminati dan kurang diminati oleh pelanggan. Akibatnya, strategi penjualan tetap tidak menentu, dengan menumpuknya produk-produk yang tidak terjual dan produk-produk yang banyak terjual terkadang kehabisan stok. Hal ini mengurangi keakuratan keputusan saat mengelola inventaris dan strategi penjualan. Seperti yang diuraikan diatas, maka dari itu dibutuhkannya klasterisasi pada data penjualan di Toko Ritel Accessories mengelola inventaris produk retail untuk menghindari kesalahan penempatan produk retail dan pengelompokan yang tidak teratur. Tujuan dari penelitian ini adalah untuk mengetahui kinerja perhitungan pada saat menganalisis data penjualan agar lebih mudah dan  akurat dalam menentukan produk mana yang disukai pelanggan dan mana yang tidak.Temuan laporan mengenai barang dapat digunakan untuk memandu pengambilan keputusan saat menentukan strategi pemasaran dan  manajemen inventaris untuk meningkatkan penjualan. Data mining yang digunakan dalam penelitian ini adalah metode clustering (pengelompokan) menggunakan Algoritma K-Means. Penerapan metode K-Means dalam pengelompokan data penjualan pada Toko Ritel Accessories menghasilkan rekomendasi barang yang diminati dan kurang diminati. Sehingga dapat mengoptimalkan strategi penjualan pada toko, meningkatkan efisiensi operasional, dan memberikan pengalaman belanja yang lebih baik kepada pelanggan Algoritma ini akan mengelompokkan data penjualan ke dalam klaster yang diproses menggunakan tools rapidminer untuk memproses hasil barang yang diminati dan kurang diminati. Setelah menhgasilkan nilai DBI dengan metode K-Means dari k-2 sampai k-10 yang terdapat pada tabel diatas, dapat dilihat bahwa cluster yang terkecil yaitu k-5, dengan nilai DBI 0,286. Karena nilai k-5 merupakan nilai terkecil dibandingkan k lainnya, maka dapat disimpulkan bahwa k-5 dengan nilai 0,286 merupakan hasil cluster terbaik.

PERIPHERAL NERVE BLOCKS IN GERIATRIC ORTHOPEDIC ANESTHESIA FOR HIP FRACTURES: UNVEILING ECONOMIC AND CLINICAL DIMENSIONS
Authors: Emery Niyonkuru  , Xu Zhang  , Peng Ma
Published: April 2024

Hip fractures in elderly patients significantly burden health and healthcare costs. Effective pain management is crucial for optimal recovery, prompting the exploration of innovative strategies like peripheral nerve blocks (PNBs). This review investigated the clinical and economic impact of PNBs on geriatric patients undergoing hip fracture surgery. A systematic review identified relevant research on PNB use in this population, searching databases like PubMed, Cochrane, and others for studies published before September 2023. The findings revealed several potential benefits associated with PNBs, including targeted pain control, decreased opioid dependence, and facilitated earlier mobilization. Notably, the analysis highlighted a dual impact, with PNBs demonstrating potential clinical advantages like shorter hospital stays and fewer complications alongside their costs. However, the evidence of their influence on healthcare costs remains inconclusive. Despite the uncertainty surrounding cost-effectiveness, the overall trend suggests positive clinical outcomes associated with PNBs, including improved recovery and reduced opioid reliance. These potential benefits could translate to a positive impact on healthcare resource utilization.
In conclusion, PNBs show promise for improved clinical outcomes and potentially reducing healthcare resource utilization. To solidify cost-effectiveness, future studies should pinpoint economic benefits and refine PNBs use. A more thorough analysis is needed to confirm these financial advantages.
KEYWORDS: hip fracture, peripheral nerve blocks, elderly, hospitalization duration, healthcare costs.

Published: April 2024

In recent times, there has been increased participation of women in agricultural value chain, but their empowerment status is poor. Thus, evidence-based data revealing the socio-economic status of rural women participating in maize value chain is important to further strengthen women’s participation in the agricultural value chain sector. The study aimed at examining participation in maize value chain and socio-economic empowerment among women in South-west Nigeria. A three-stage sampling procedure was employed in the selection of respondents for the study. The first stage involved proportionate random sampling of three states in South-west, Nigeria. Second stage involved the generation of a sample frame from the various associations of rural women farmers in MVC in the Agricultural Development Programme zones. Last stage, 20% of the total of rural women farmers involved in MVC was selected to give a sample size of 539 respondents. Data were collected through interviewer-administered questionnaire and analyzed using both descriptive and inferential statistics. The findings from the study were that the participation mean score of the respondents in marketing and processing were high (71.2%, 73.1%) respectively, the mean participation score in MVC was 67%; respondents’ percentage mean score based on socio-economic empowerment status after participation in MVC was high (60%). Major constraints to participation in MVC activities were high cost of transportation to market (x̄=1.27) ranked 1st and inadequacy of extension service delivery (x̄=1.22) ranked 2nd; and participation in MVC activities had positive and significant relationship with the socio-economic empowerment status of the respondents (r=0.380; p=0.000). The study concluded that the level of rural women farmers’ participation in MVC activities was high and impacted their socio-economic status positively. The study recommended that agricultural extension agency should focus on empowering the rural women by providing extension services needed for market linkage and bulk transportation of produce to target markets.

Based on the results of hydrometeorological observations in the period 2016-2021, the parameters of the optimum temperature zone (TTO) for the process of mass development of cyanobacteria in the Kuibyshev reservoir were determined. Such parameters of the optimum zone as duration, intensity, upper and lower boundaries depend on the hydrometeorological conditions of a particular year. For the period 2016-2021, the average duration of the OST was 44 days, the longest - 72 days and was observed in 2021, and the shortest - 11 days and was observed in 2019. The highest intensity of OST was observed in 2021, when 10 days were characterized by low intensity, 15 days by moderate intensity, 23 days by strong intensity, 24 days by very strong intensity and 7 days by extreme intensity. The lowest intensity was observed in 2019, when 10 days were characterized by low intensity and 1 day by high intensity. The upper border of the WTO in 2021 was observed on June 21, and the lower border on September 1. In 2019, the upper limit was observed on June 23, and the lower limit on July 26. For the process of mass development of cyanobacteria, the most favorable year is 2021, and the unfavorable year is 2019. It was found that with the increase in air and water temperature, the duration and degree of intensity of the temperature optimum zone increased. Consequently, with a further increase in air temperature due to global warming, the duration and intensity of the optimum temperature zone will only increase, which will activate the process of mass development of cyanobacteria, which will negatively affect the ecological state and water quality of the Kuibyshev reservoir.

Cyanobacterial blooms of continental freshwater reservoirs are currently one of the global challenges facing humanity. The main factors increasing the scale and frequency of cyanobacterial blooms are increasing human population, intensification of agriculture, growth in industrial production, increased consumption of ores and other minerals, and global climate change. Mass development of cyanobacteria causes the breakage of trophic links between primary producers and consumers, leading to the excessive accumulation of cyanobacterial biomass and soluble products of their metabolism and autolysis, including biologically active secondary metabolites and cyanotoxins, and contributes to the formation of hypoxic conditions in the water column. Cyanobacterial blooms significantly reduce the consumer qualities of aquatic ecosystems, including their recreational attractiveness, water quality and its suitability for drinking and household purposes. The main reason for the excessive development of phytoplankton in continental freshwater reservoirs is the influx of an excessive amount of nutrients, primarily phosphorus, as well as a decrease in water circulation, causing stagnation, and high air temperatures, leading to excessive heating of water for a long period. The requirement of specialized monitoring is emphasized in order to assess and control the factors leading to the mass development of certain species of cyanobacteria. The review discusses the main bloom-forming species of cyanobacteria in freshwater reservoirs, the features of their development and environmental requirements, the consequences of cyanobacterial blooms for aquatic ecosystems and the population. The necessity of reducing the external biogenic load on reservoirs as the most important condition for the long-term prevention of cyanobacterial blooms is emphasized. An overview of various intra-reservoir methods of restoration and rehabilitation of reservoirs is given. Since their effectiveness strongly depends on the limnological and hydrobiological characteristics of the reservoir, the choice of certain methods should be based on a complete and comprehensive description of the ecosystem of the rehabilitated reservoir.

The data on helminths of the digestive system of the bream Abramis brama Linnaeus, 1758 and the common roach Rutilus rutilus Linnaeus, 1758 (Osteichthyes, Cyprinidae) from the middle part of the Saratov reservoir (Koltsovo-Mordovinskaya fl oodplain) are given. In 2013–2016, 40 specimens of A. brama and 47 specimens of R. rutilus were studied by standard parasitological methods. Bream has 8 species of worms of different systematic groups, including Cestoda – 2, Trematoda – 1, Chromadorea – 3, Acanthocephala – 2. The community of intestinal and liver parasites of roach includes 5 species: Cestoda – 1, Aspidogastrea – 1, Chromadorea – 2, Acanthocephala – 1. The degree of invasion of fi sh by helminths circulating through food webs is low. The bream is dominated by the carp-specifi c nematode Rhabdochona denudata (Dujardin, 1845) Railliet, 1916 (Spirurida, Rhabdochonidae) (invasion intensity 27.5 %, invasion intensity 1–126 ind., abundance index 5.8 ind.). No dominant parasites were found in the common roach, three species (Contracaecum microcephalum (Rudolphi, 1819), Aspidogaster limacoides Diesing, 1835 and Raphidascaris acus (Bloch, 1779)) have the status of subdominants. During the research period, there were signifi cant fl uctuations in the qualitative and quantitative indicators of fi sh invasion (species composition of parasites, their occurrence and average number), which is determined by the feeding characteristics of bream and roach in each specifi c year.

For the fi rst time data on the composition and structure of helminth fauna and the degree of helminth infection of amphibians of the Usa River basin, Samara region, are summarised. In the period from 1999 to 2023, 100 specimens of 4 species of tailless amphibians were examined by the method of complete helminthological autopsy: Pelophylax ridibundus, Rana arvalis, R. temporaria and Pelobates vespertinus. Twenty-one species of helminths of two classes, Trematoda (17) and Chromadorea (4), were recorded. The helminthofauna of Pelophylax ridibundus is the richest (20 species), the “core” of which consists of fi ve trematode species: Skrjabinoeces similis, Opisthioglyphe ranae, Pleurogenes claviger, Pleurogenoides medians and Prosotocus confusus. The helminthofauna of Pelobates vespertinus (5 species), Rana arvalis and R. temporaria (1 each) is impoverished. The structure of the helminthofauna and peculiarities of infection by certain trematode species are of “river” character and are similar to those in the fl oodplain of the Sok River. On the coast of the Usinsky Bay, Pelobates vespertinus has a pathogenic trematode species Alaria alata (Goeze, 1782), which is the causative agent of alariasis, a dangerous helminthiasis of domestic and wild carnivores.

Chitin-containing materials were most widely used in wastewater treatment. In production processes accompanied by the release of proteins, chitosan is used as a flocculant in the treatment of contaminated wastewater. Using chitosan, metals are extracted from mining waste. The introduction of chitosan into the soil leads to the removal of scattered heavy metals and radionuclides from the natural cycle.There are a number of patents in the field of water treatment using chitosan. However, there is much less work on the use of chitin and chitosan as a sorbent for oil and oil products. Alaa Eldin Muhammad Younes et al used chitin and chitosan to remove Tengiz oil spills from the water surface. At the same time, oil with chitin formed clots, which eventually (~ 2 hours) precipitated. On the contrary, chitosan forms floating clots, which contributes to their extraction. The authors on the model systems determined the flow rates for the collection and removal of oil film from the surface of 1 m2. This is 0.16 kg of chitin or chitosan with an amount of 10% of the sorbent based on the weight of the oil film. It has been suggested that extractable products can be used in asphalt concrete pavements. A high degree of water purification (up to 99.8%), and almost complete purification of waters containing oil emulsions makes it possible to recommend it as a highly effective flocculant with its content of 0.0028. It is characteristic that chitosan works better with a high oil content in water. However, efficient recovery of chitosan with absorbed oil remains an unresolved issue. In this case, oil flows from the sorbent, leading to secondary pollution. The invention proposes a method of oil and petroleum product spill response and purification at water bodies, as well as reduction of environmental pollution by waste water of industrial enterprises with the help of highly efficient, economically justified sorption material based on chitosan and semi-rigid polyurethane foam and a technological process of its production. Sorption material using crushed chitosan soluble in acid in amount of 30% of total weight and elastic polyurethane foam PPUel-30-HC has optimal absorption capacity of ~ 14.0 g/g at weight ratio of sorption material components A: B: chitosan = 1: 0.6: 0.48. The environmental friendliness of the developed sorption material is confirmed by the possibility of its repeated use up to 19 times after squeezing the absorbed product without significant changes in oil capacity. Disclosed is a technological scheme for producing a developed sorbent named Grinsorb X and a method for eliminating oil spills using it.

In this paper main regularities of distribution of radionuclides in dependence of the method of treatment of oil-containing wastes have been analyzed. Calculation of limit values of the specific effective activity of natural radionuclides have been carried out. Results of experiments are showing that during the burning of oil sludges samples the analyzed radionuclides behave the same in all cases. The relationship between migration coefficients and ash content has been also established. For the samples with more high ash content during the burning the coefficients of migration of radionuclides into the remaining ashes were high than for the samples with the lower values of ash. Estimation of migration of natural radionuclides 226Ra, 232Th and 40Kin the processes of treatment of oil-containing wastes (burning, extraction of oil products, distillation of the diesel fraction) has been carries out. It was determined that during the carrying out of these processes the radionuclides are concentrated in more solid processes products: in ash, solid residue and bitumen fraction. As result, it increases their specific effective activity. The dependence of the coefficients of migration of radionuclides from the ash and the con tent of the mechanic impurities during the treatment by the methods of burning and extraction of oil products has been also received. Using of the results of work is allowing us to select the most appropriate methods of treatment of oil-containing wastes and to reach significant reduction of radioactive nuclides negative impact to the humans and to the environment.

Authors: Çerpja Teuta , Murrja Arif
Published: April 2024

The risk of entrepreneurship in agriculture is complex. The purpose of this study is to identify and analyze the primary market risks that farmers face, which will help them better understand these risks and make informed decisions to mitigate them. The research uses a mixed methodology involving descriptive statistical analysis and multifactorial regression analysis to examine four critical risk factors: changes in consumer preferences, price fluctuations, high competition, and shifts in consumer incomes. The findings show that only high market competition is statistically significant and has a substantial impact of 79%. Farmers can use this information to adjust their production focus towards areas of comparative advantage in a single crop to improve their financial stability. In summary, market risk analysis is an essential tool that empowers farmers to understand and manage risks effectively to safeguard their income streams.
