AbstractThe application of learning has so far been less accepted by children or less interesting so that children ignore it and are not interested. Therefore, the use of interesting methods such as telling stories using letter cards can improve children's reading skills. The purpose of this researcher is to improve children's ability to recognize letters in early childhood through letter cards in the PGRI Serutsadang Kindergarten. The research method used in this research is the Class Action Research (PTK) method which consists of two cycles and each cycle has three meetings. The subjects of this study were group B children in the 2022/2023 school year, which consisted of 20 children. Research data collection techniques, namely through observation, interviews and documentation studies. Based on the results of the study, it was shown that by using letter card games students could participate in the process happily and enthusiastically, they listened and understood well. After using the storytelling method using letter cards, children's reading ability has increased significantly. This can be seen when the children are resting, many children are interested in reading in the reading corner. The percentage of children who know letters is only 5% of children in the pre-cycle, but the frequency of children who know letters increases to 90% of children after being given the letter card game method for 2 cyclesKeywords: Word Cards; Recognizing Letters; Game; Child's Ability; AbstrakKurangnya kemampuan anak dalam mengenal huruf dan menggabungkannnya menjadi suku kata menjadi latar belakang penelitian ini, hal tersebut juga dipengaruhi oleh penerapan pembelajaran masih konvensional kurang menarik sehingga anak-anak mengabaikan dan tidak tertarik.

Fikcje antropocenu. Literatura XXI wieku wobec katastrofy klimatycznej
Authors: Żółkoś Monika
Published: June 2023

This article explores narrative trajectories of conceptualizing climate change in modern literature. The main goal is to extend frames of Anthropocene fiction beyond science fiction genre in novels written in the twenty-first century. Taking humanistic approach to climate crisis as a starting point, the article concentrates on strand of literature based on realistic convention that presents planetary crisis not as futuristic phantasy but as contemporary process. Drawing on the work of Richard Powers, Maja Lunde, Charlotte McConaghy, Barbara Kingsolver, Sigriđur Hagalin Björnsdóttir, and Hanya Yanagihara, I argue that thay create subgenre od climate fiction that present planetary catastrophe in non-spectacular and unconventional way to regain affective power of literature and provoke imagination. Another important aspect is narrative construction of time in their novels, which concentrate on compering different moments in planetary chronology to present human kind as one of many episodes in process of life shaping on Earth and thereby to challenge anthropocentric approach to problem of climate change.
Mycelium Matter(s) – Fictionalizing Human–Mushroom Relations
Authors: Joshi Vishwaveda
Published: June 2023

Through this paper, the author tries to explore a simple yet complex question: how do we decentralize the human presence in conversations about climate-change? To do so, this speculative climate 2ction is presented through the non-human narrative perspective of mycelium (fungi). The speculative fiction provides a space for re-thinking our ontological and epistemological strategies and categorizations of nature/culture division, as well as how we understand nature in relation to human.The speculative climate-fiction proposes a reconsideration of human in relation to nature/climate, through fungi. It further explores how sensory, bodily, and multimodal methodologies may work in interaction to produce new possibilities to explore the corporealities of human-nature relationships and how a non-anthropocentric understanding of climate-change can allow for an emerging engagement with a vast mesh of human and beyond-human agencies. Drawing inspiration from Sylvia Plath, Ursula K. Le Guin, Margaret Atwood, and using Erin Manning’s understanding of a5ect as having a feltness that we often experience as a becoming-with, in this case, a becoming-with nature, the speculative-fiction (SF) is written as a dialogue between fungi and human. The SF also uses artwork created with mushrooms, fungal roots, as well as mushroom extracts, to exaggerate the presence of beyond-human beings in a new onto-epistemic strategy that reconsiders climate change and human–nature relationships.
„Próba generalna” współ-odczuwania z nie-ludźmi w opowiadaniu Olgi Tokarczuk
Authors: Kamiński Szymon
Published: June 2023

The work reflects Olga Tokarczuk’s short story Dress Rehearsal which deals with the topic of apocalypse, climatic catastrophe, and climate change. The article is a part of a scientific work, which is a master’s thesis dealing with the complex issue of the subjectivity of animals and nature, as well as the common environment and post-environment, and the study of the relationship between humans and non-humans. In the work, the Nobel Prize winner comes under the influence of a ‘world-creator’ and an ‘intense observer’, thus human relations can be complicated in times of the end of the world and how human attitudes towards animals and the world change. This time of the end, marked by Giorgio Agamben with the messianic era, allows for a certain non-action towards reality, and empathy and compassion begin being a remedy for centuries of objectification of other beings.
O kryzysie klimatycznym z perspektywy nieetnocentrycznej (na przykładzie filmu anime „Nausicaä z Doliny Wiatru” Hayao Miyazakiego)
Authors: Filipowicz Anna
Published: June 2023

The article raises the problem of non-Eurocentric approaches to natural disasters – treating them as ordinary rather than traumatic events. For some archaic (indigenous) types of thinking, fundamental changes taking place in the environment do not cause the cessation of relations with nature and involve the need to constantly adapt to its conditions, even at the expense of one’s own welfare or living. Hayao Miyazaki’s anime film Nausicaä of the Valley of the Wind also discusses this issue. The animistic thinking about the environment (Japanese Shintoism) shown in it opens a reflection on the possibility of considering old worldviews in the reflection on the ethical future of man on the eve of the climate collapse.

Published: June 2023

The results of the experiment on the use of functional additive in the diet of growing quails on the basis of natural organomineral complex (sapropel) enriched with wheat bran, coniferous flour, pine nut shells and enzyme preparation Fitbest WP are presented. The experiment lasting 60 days was conducted according to the standard methodology on Japanese quails. For the experiment, two similar groups of 60 birds each (one control and one experimental group) were formed at one day of age. Both groups received basic mixed fodder corresponding to the physiological characteristics and age of the quails. In the ration of young animals of the experimental group 10% of the wheat mass was replaced by a functional additive consisting of sapropel (50%), wheat bran (20%), coniferous flour (15%) and pine nutshells (15%), enriched with the enzyme preparation Fitbest WP (100 g/t mixed fodder) designed to increase the absorption of phytate phosphorus. The birds were kept in a cage battery under the required microclimate conditions. The effect of feeding the experimental additive on the following indicators of quail chickens was studied: safety, average daily gain of live weight, meat productivity and meat quality, biochemical composition of blood. Introduction of the functional additive on the basis of natural premix (sapropel) into the mixed fodder of quails increased the safety of birds by 2.00%, live weight gain by 6.97% with no significant differences in the consumption of mixed fodder per unit production. The meat of the poultry that consumed the functional additive increased the dry matter content by 0.85%, ash by 0.61%, calcium and phosphorus by 1.05 and 1.30 times (p < 0.05). Intergroup differences in protein content and fat content were insignificant. Hematological parameters of quail chickens in the experimental groups corresponded to the physiological norm.

Authors: Moskvichev A. Yu. , Agapova S. A.
Published: June 2023

The purpose of the research is to find out the reaction of soybean plants to seed inoculation under different irrigation regimes (humidity not lower than 80% MWC (minimum water capacity) in the layers 0,4 and 0,6 m, differentiated by stages of growth and development water regime at the level of 70-8070% MWC in the layers 0,4 and 0,6 m) in the Lower Volga region conditions. The object of the study is soybean crops of the Volgogradka 2 variety selected by the All-Russian Scientific Research Institute of Irrigated Agriculture (VNIIOZ). The experiment was conducted in 2021 and 2022 on the experimental field of VNIIOZ. Geostim Fit G produced by Biotechagro (Timashevsk, Krasnodar Territory) was used asan inoculant at a concentration of 5-10 l/ha. For foliar feeding biopreparations, natural mineral bilator and fungicide Kolosal Pro were used. Based on the data obtained, it was found that the maximum increase in productivity (132%) was obtained by seed inoculation before sowing in the variant with a soil moisture level of 80% MWC. With differentiated water treatment, the productivity was 129% compared to the untreated control. Of the agents used during the growing season to control pathogens, preference should be given to biopreparations. The volume of the harvested grain was maximum (3.87 t/ha) in the control variant with soil moisture of 80% MWC and the use of seed inoculation. The second result in terms of productivity showed the variant with the use of natural mineral bilator (3.38 t/ha), the minimum yield (2.86 t/ha) was recorded in the case of using the chemical agent Kolosal Pro. The calculation of economic efficiency showed the profitability of soybean crops treatment with biological preparations. The scientific novelty of the study is that in the course of its implementation for the first time for the conditions of the Lower Volga region the efficiency of soybean cultivation was determined taking into account the influence of several factors at once: soil water regime, seed pre-sowing treatment with inoculants, treatment of plants during vegetation to control pathogens.
Influence of microfertilizers of the Izagri series on the productivity of safflower (Carthamus tinctorius)
Authors: Prakhova T. Ya. , Druzhinin V. G.
Published: June 2023

The results of the analysis of the influence of Izagri microelement fertilizers on safflower productivity in the forest-steppe conditions of the Middle Volga region are presented. The studies were conducted in 2020-2022 in the Penza region (experimental field of the Penza Research Institute of Agriculture). The object of the study was safflower of the Ershovsky 4 variety. The experiment consisted in pre-sowing seed treatment with Izagri series of microfertilizers. Izagri preparations were found to increase the growth force of seeds up to 1.21-1.57 cm, germination by 1.1-8.8%, safety of plants for harvesting by 0.5-6.2%. Against the background of fertilizer application, safflower productivity averaged 1.30-1.55 t/ha for 3 years, i.e. increased by 0.06-0.25 t/ha. The greatest effect was produced by Izagri Force and Izagri Vita, which helped to obtain a yield increase of 0.23-0.25 t/ha. The highest oil content of seeds was observed in the variants with Izagri Azot (29.85%) and Izagri Bor (30.04%): the increase was 2.7 and 3.0% respectively. Application of these preparations reduced seed huskiness to 37.7 and 37.9%, respectively. The largest seeds were formed in the variant with Izagri Vita - weight of 1 thousand seeds was 39.16 g. Treatment with Izagri Phosphorus and Izagri Vita gave a slight decrease in oleic acid content (to 9.94 and 9.62%). At the same time, the use of Izagri Vita maximized the amount of linoleic acid (up to 83.63%). After using Izagri Force, the concentration of this acid decreased to 81.88%. Based on the data obtained, it can be concluded that pre-sowing treatment of seeds with microfertilizers from Izagri line improves the quality indicators of oilseeds and can act as a method to increase the productivity of safflower.

Published: June 2023

The effect of cavitated sunflower husk and lactic acid on the changes in the taxonomic profile of the rumen microbiome of ruminants in vitro was evaluated. Changes in the bacterial composition of the cicatricial fluid were determined by using the MiSeq sequencing method in a time exposure of 6-24 h. The objects of research were sunflower husk milled (0.01 cm) - control; cavitated: husk and water in a ratio of 1 : 3, treated with ultrasound; husk and lactic acid in a ratio of 1 : 3 - cavitated husk + lactic acid. The obtained samples after drying at 105 ºC were used in in vitro studies with rumen fluid on an incubator (analog of artificial rumen). Selection of the rumen fluid in cattle was carried out through a chronic fistula. The age of animals - 12 months, the breed - Kazakh white-headed. Administration of cavitated sunflower husks alone or together with lactic acid after 6 h increased the number of bacteria belonging to the Flavobacteriia class by 5.43 and 3.93%, Elusimicrobia by 3.77 and 3.98%, Gammaproteobacteria by 11.75 and 10.07% and decreased the number of Bacteroidia by 5.72 and 2.63%, Clostridia by 3.26 and 2.20% relative to the control. In contrast, in the 12-24 h exposure time, there was an increase in Bacteroidia class bacteria by 3.30-4.90 and 8.29-11.28%, Clostridia by 1.66-1.50 and 2.74-3.27% relative to the control.

Published: June 2023

Background

Surveillance of SARS-CoV-2 in wastewater offers a near real-time tool to track circulation of SARS-CoV-2 at a local scale. However, individual measurements of SARS-CoV-2 in sewage are noisy, inherently variable and can be left-censored.

Aim

We aimed to infer latent virus loads in a comprehensive sewage surveillance programme that includes all sewage treatment plants (STPs) in the Netherlands and covers 99.6% of the Dutch population.

Methods

We applied a multilevel Bayesian penalised spline model to estimate time- and STP-specific virus loads based on water flow-adjusted SARS-CoV-2 qRT-PCR data for one to four sewage samples per week for each of the more than 300 STPs.

Results

The model captured the epidemic upsurges and downturns in the Netherlands, despite substantial day-to-day variation in the measurements. Estimated STP virus loads varied by more than two orders of magnitude, from ca 1012 virus particles per 100,000 persons per day in the epidemic trough in August 2020 to almost 1015 per 100,000 in many STPs in January 2022. The timing of epidemics at the local level was slightly shifted between STPs and municipalities, which resulted in less pronounced peaks and troughs at the national level.

Conclusion

Although substantial day-to-day variation is observed in virus load measurements, wastewater-based surveillance of SARS-CoV-2 that is performed at high sampling frequency can track long-term progression of an epidemic at a local scale in near real time.

Radiological approach to multinodular and vacuolating neuronal tumor: Two case report
Authors: Ocak Karataş Şükrüye Firuze , Beyhan Murat , Gökçe Erkan
Published: June 2023

Multinodular and vacuolating neuronal tumors (MVNT) are indolent, low-grade, superficial neuronal tumors of the cerebrum that consist only of neuronal cells in adults. They were first reported in 2013 by Huse et al. and defined by the World Health Organization in 2016. MVNT is characterized by vacuolated tumor nodules with glial and/or neuronal differentiation histopathologically. MVNT is most commonly located in the temporal lobe. Radiologically, it has a subcortical, soap-bubble morphology, sometimes extending to the cortex, and is almost as hyperintense as cerebrospinal fluid on T2-weighted images. Its signal is not suppressed on the FLAIR sequence, and there is no diffusion restriction on diffusion-weighted images. Usually, there is no enhancement after gadolinium injections, but a few reports show weak enhancement in the literature. In the first case, we present a 22-year-old female with MVNT who underwent MRI for a complaint of dizziness which was detected incidentally. MRI showed a clustered multinodular lesion in the left superior frontal gyrus that was hyperintense on T2-weighted/FLAIR series and isointense with gray matter on T1-weighted images. There was no diffusion restriction or contrast enhancement on MRI. In the second case, a 51-year-old female with complaints of numbness and pain in her left arm had an MRI that showed a lesion in the right cerebral hemisphere at the temporoparietal junction. The lesion did not cause edema or mass effect and was distributed in the cortical-subcortical area. The lesion was hyperintense in T2-weighted and FLAIR series and consisted of many millimetric nodular components in close intensity with gray matter in the T1-weighted series. No contrast enhancement was detected. Knowing the characteristic imaging findings of MVNT is important in avoiding aggressive diagnosis and treatment approaches in asymptomatic cases. In conclusion, MVNT is a newly identified tumor that appears hyperintense on the FLAIR sequence and should not be operated on.

The stem nodulating leguminous green manure Sesbania rostrata has great potential as an effective bioresource material for rice production due to higher biomass production and N, contribution. Attempts were made to extend the symbiotic N, fixation to non-legumes such as rice. The symbiont Azorhizobium caulinodans ORS 571 upon inoculation, stimulated the lateral root development as well as formation of nodular like structures in the roots of rice. Colonization of lateral root cracks by A. caulinodans ORS 571 was found to be stimulated by the flavonoid naringenin. Rice seedlings growing aseptically in the presence of naringenin were inoculated with A..caulinodans ORS 571 (pXLGD4) carrying the lac Z reporter gene. By microscopic analysis of sections of inoculated rice roots, it has been demonstrated that the xylem of rice roots can be colonized by Azorhizobium caulinodans. This could provide a suitable niche for endophytic nitrogen fixation by A. caulinodans in rice.

Authors:   Plant Pathology Division,Sugarcane Breeding Institute,Coimbatore 641 007 Tamilnadu, R VISWANATHAN
Published: June 2023

Experiments were conducted to study the role of anthocyanin pigment in sugarcane red rot disease resistance in response to C. falcatum infection. In resistant cultivars, anthocyanin levels were always higher after pathogen inoculation between 24 and 240 h than in susceptible cultivars. In resistant cultivar anthocyanin accumulation in pathogen inoculated canes was higher over the injured canes at all intervals, however, in susceptible cultivar, such accumulation was noticed upto 48 h only. Anthocyanin extracted at 72 h after inoculation had maximum antifungal activity on the pathogen. Higher anthocyanin synthesis occurred in incompatible interactions than in comptible interactions. Partially purified pathogen toxin also induced multifold increase in anthocyanin accumulation in the resistant genotype than in the susceptible genotype.

Studies to assess the effects of intercropping in tomato under irrigated and rainfed conditions for the management of key pests at Regional Research Station, Paiyur, TamilNadu. Agricultural University, TamilNadu during 1998-2000. Experiments were conducted in a factorial randomized block design using intercrops viz, clusterbean, green gram and mustard and two rounds. of spraying with NSKE 5% and monocrotophos 0.07%, once on 30th day after transplanting and second at the time of maximum flowering and fruit set. The results revealed that tomato intercropped with mustard at 2:1 ratio had recorded reduced incidence of whitefly and thrips population and fruit borer damage as well in two different field studies. Natural incidence of tomato spotted wilt virus (TSWV) and leaf curl virus (LCV) diseases. were noticed on the rainfed tomato crop raised during August-September, 1999 planting season. The incidence of TSWV and LCV diseases were less under intercropped tomatoes than sole crop tomato and this was significantly low on the mustard intercropped plots. Nearly 30% of plants were lost due to these diseases in the tomato sole crop plots and this loss in plant population was nearly 45-60% more than the mustard intercropped plots. The combined yield of undamaged and damaged fruits was 16.319 t ha and 16.028 t ha for the sole tomato and mustard intercropped tomato under irrigated condition. However, under rainfed condition due to the severe incidence of viral diseases, an yield of 5.832 tha was recorded in sole crop while it was 8.527 t ha in mustard intercropped plots. The undamaged fruit yield recorded was 15.00 and 7.810 tha for the mustard intercropped plots, whereas it was 13.386 and 4.833 t ha for sole crop tomato under irrigated and rainfed conditions respectively. The mustard intercropping had given an additional net return of Rs.7080 and Rs.12400 because of reduced pest infestation under irrigated and rainfed conditions respectively.

Sixty diverse genotypes of fodder cowpea (Vigna unguiculata (L.) walp.) evaluated for the genetic diversity were grouped into 10 clusters indicating high genetic divergence among them. The clustering pattern showed that geographic diversity is not an index of genetic diversity. Based on the intercluster distance and cluster mean for various characters, it could be seen. that the clusters I, II, IX and X were the most divergent from the other clusters. The genotypes from these clusters may possibly be utilized for hybridization programme. Dry matter yield, green fodder yield and plant height contributed highly towards the genetic divergence among the types studied.

Ten brinjal accessions including two wild accessions were evaluated in glasshouse for their level of resistance and the mechanisms of resistance against Bemisia tabaci (G.). The morphological characters viz. trichome density, length, breadth and the biochemical characters viz. solanine phenols, sugars and pH play a deferential role in the preference of feeding. The accessions TS 00052 and Arka neelakanta were found to have less population and fewer trichome with higher amount of solanine, phenols, lower levels of sugars and pH. The wild type accessions manifested a high level of resistance to B. tabaci.

Thirty two paddy varieties of Tamil Nadu and Andhra Pradesh were studied for their milling performance. Among them eight promising varieties known for raw milling were grown under identical conditions at Thanjavur. The crop was harvested at right moisture, dried under low intensity of sunlight and milled at laboratory and commercial level after storing 3 and 6 months. Among the high yielding varieties, ADT 39, MTU 2069, MTU 2077, MTU 7029 and White Ponni were found suitable for raw milling, having less than 5% milling breakage. The highest milling yield was observed in ADT 39. The two traditional varieties Kitchili samba and Jeeraga samba are the best regarding their milling resistance. The widely grown White Ponni of Tamil Nadu even at 15.4% harvest moisture has shown better suncheck resistance and has very good cooking performance. Though the milling yield was high in all the MTU varieties, the cooking performance was better for the variety MTU 7029.

Objective: To evaluate the effect of using an educational booklet combined with a brief motivational interview on maternal self-efficacy in preventing childhood diarrhea. Methods: Quasi-experimental study, carried out with 35 mothers. For data collection, the Maternal Self-Efficacy Scale for the Prevention of Childhood Diarrhea (EAPDI) was applied, and later an educational intervention based on the application of the booklet “You are able to prevent diarrhea in your child!” associated with a brief motivational interview. One month after the intervention, by telephone contact, the EAPDI and a form to verify the occurrence of diarrhea were applied. For data analysis, statistical tests were applied. The study was approved by the Research Ethics Committee. Results:Houve aumento dos escores de autoeficácia materna em prevenir a diarreia infantil ao longo do estudo (p 0,001), aumento progressivo do número de mães que apresentaram alta autoeficácia (p 0,001) e diminuição da ocorrência de casos de diarreia um mês após a intervenção (p 0,021). Conclusões: A intervenção educativa ajudou a aumentar a autoeficácia materna na prevenção da diarreia infantil e na redução dos episódios de diarreia nas crianças, revelando-se também um instrumento capaz de aumentar a autonomia das mães no cuidado das crianças.

Over the last few years, the use of the fuzzy logic technique for evaluating performance in the teaching-learning process is growing rapidly. In this research work, three different fuzzy inference methods: Mamdani fuzzy inference method, Larsen fuzzy inference method and Tsukamoto fuzzy inference method have been proposed for students' academic performance appraisal for multi-input variables. To obtain a degree of satisfaction, the Triangular membership function is used. The results of experiments showed the best fuzzy inference method among Mamdani, Larsen and Tsukamoto. We have also compared the results with the existing statistical method.
Effect of groundwater level on slopes to construct the SWCC curve for unsaturated soil
Authors: Dang Khoa Pham Ngoc  , Vinh Pham Quang
Published: June 2023

The occurrence of landslides and rockfalls has been on the rise, leading to unfortunate consequences and instilling anxiety and fear within the population as the rainy season approaches. During this time, the soil experiences a significant influx of water, causing the water level to rise and the transition from unsaturated to saturated soil. As a result, the shear strength of the soil decreases, leading to gradual slope instability. While the parameters of unsaturated soil resemble those of saturated soil, the inclusion of a SWCC curve is necessary. This study aims to examine the impact of groundwater levels on slope stability by considering the SWCC curve of the soil using the finite element method. The findings reveal that with an increasing groundwater level, the safety factor remains constant when the slope is assumed to be fully saturated. However, when the slope is evaluated with both fully saturated and unsaturated components using the SWCC, the safety factor declines significantly from 1.82 to 0.393. Similarly, according to the Fredlund-Xing method, the safety factor decreases from 1.754 to 0.393. Regardless of the method used, the safety factor consistently decreases as the groundwater level rises, eventually converging to the same value when the groundwater level reaches the ground surface.

Published: June 2023

This study was conducted to investigate and assess the microbiological quality and organoleptic properties of smoked dried fish sold in Wukari markets, Nigeria. Eight samples of smoked dried fish (SA,CA,MB,SC,TP,CO,SA1,SA2) were analyzed for microbial quality and organoleptic properties using standard methods. The total bacteria aerobic plate count of bacterial cells ranged from 1.31 × 106 to 2.22 × 107, coliform count 1.00 × 105 to 7.40 × 106, Staphylococcal count 4.00 × 106 to 6.10 × 106 and fungi 1.50 × 106 to 8.3 × 106 cfu/g in the fish samples respectively. The microbial load of all samples was higher than the acceptable limit of 5.0 × 105 cfu/g. Identification of bacterial isolates revealed the presence of Staphylococcus aureus, Staphylococcus epidermidis, Bacillus spp, Pseudomonas spp, Escherichia coli, Salmonella typhi and Klebsiella spp. The mould isolates were Aspergillus niger, Aspergillus flavus, Penicillium and Clasporium. From the sensory evaluation of all samples, shawa was the most preferred in terms of appearance, colour, tenderness, aroma and general acceptability. Kulungu was the least preferred in terms of appearance, colour and texture, catfish and tilapia were the least preferred in terms of aroma and ragon ruwa was the least preferred in terms of tenderness and general acceptability. In conclusion, the presence of some pathogenic microorganisms isolated from this study is an indication that samples were contaminated and can potentially pose a health hazard to the consumers. Thus, there is need for smoked fish sellers and marketers to take hygienic measures during smoking and handling of smoked fish so as to avoid contamination.

Published: June 2023

Abstract: This report's objective is to offer a thorough study of studies looking at ICT tools for kids with autism spectrum disorders. ICT assessment tools and ICT intervention tools are two categories for them. The evaluation describes each tool's background, functionality, and relationship to this scientific discipline while explaining specific technological features. The result is that a variety of ICT technologies can help with ASD diagnosis. ICT intervention tools, on the other hand, cannot be very promising. This is because there is now no effective way to cure these illnesses completely. Furthermore, since the tests haven't been conducted for a long time, the results cannot be relied upon.
