Authors:   The Korean Career·Entrepreneurship & Business Association, Seo Keonkyo , Chun Byungjune
Published: December 2024

This study aims to explore the potential of Electroencephalography (EEG) application in Korea’s career, entrepreneurship, and management fields, driven by advancements in AI and neuroscience. The objective of this research is to systematically analyze domestic research trends and present academic and practical implications for the use of EEG. To achieve this, 14 papers published in Korean academic journals registered with the National Research Foundation of Korea between 2006 and 2023 were analyzed, focusing on the year of publication, research methods, research subjects, data collection and processing, and key dependent variables.
The results indicate that EEG research is gaining attention in the fields of career, entrepreneurship, and management. The usefulness of EEG has been validated, particularly in entrepreneurial decision-making, creative problem-solving skills, and stress management. EEG has been effectively utilized in studies on business problem-solving, consumer behavior, and advertising effect analysis to measure cognitive and emotional responses in real-time. While early research mainly combined EEG with surveys, recent studies have increasingly adopted data-driven approaches, including behavioral experiments and machine learning. The primary research subjects were university students and young adults. For data collection, equipment with 8-channel, 14-channel, and 64-channel configurations was mainly employed, focusing on detailed analysis of various brain regions’ activities. EEG has proven useful for evaluating job suitability, analyzing entrepreneurs’ stress responses and creative thinking patterns, and assessing cognitive load in consumer behavior analysis and team decision-making through Event-related Potentials (ERP) analysis. This demonstrates the potential of EEG to enhance problem-solving capabilities in career, entrepreneurship, and management, supporting personalized talent development and strategic management planning.
This study highlights the expansion potential of EEG research in the fields of career, entrepreneurship, and management, serving as a foundational resource for future studies. It emphasizes the need for diverse research subjects and the exploration of practical applications in real business settings. Furthermore, the study discusses EEG’s potential as an advanced methodological tool to support decision-making, creativity enhancement, and stress management through a neuroscience-based approach.
The Effect of Entrepreneurship of Young Self-Employed on Business Performance: Focusing on the moderating effect of positive psychological capital
Authors:   The Korean Career·Entrepreneurship & Business Association, Lee Jooyoung , Kim Jongsung
Published: December 2024

In the ecosystem of self-employment in South Korea, while the number of middle-aged self-employed individuals is increasing, the number of young self-employed individuals is decreasing. Additionally, the low business survival rate among young self-employed is leading to aging and reduced dynamism in the sector. One possible solution to this issue is to enhance the business performance of young self-employed individuals by creating new opportunities, expanding business domains, and increasing profitability. However, existing studies on young self-employed individuals have largely focused on analyzing their characteristics, without providing comprehensive solutions to improve their business performance. Therefore, this study aims to propose ways to enhance the business performance of young self-employed individuals, It focused on entrepreneurship and positive psychological capital.
This study hypothesizes that the entrepreneurship of young self-employed individuals influences their business performance and that positive psychological capital plays a moderating role by strengthening this relationship. The results of the study are as follows: First, among the elements of entrepreneurship, innovativeness, risk-taking, and proactiveness positively influence financial performance, and self-efficacy, as a component of positive psychological capital, plays a moderating role by weakening this relationship. Second, risk-taking and proactiveness positively influence customer performance; however, none of the components of positive psychological capital were found to have a moderating effect in this relationship. Third, risk-taking and proactiveness positively influence internal process performance, and hope and resilience, as components of positive psychological capital, act as moderators by enhancing this relationship. Fourth, innovativeness and proactiveness positively influence performance from the learning and growth perspective, and hope and resilience were confirmed to have a moderating effect in this relationship.
This study holds academic significance as it empirically analyzes the factors influencing the business performance of young self-employed individuals, who have been somewhat neglected as a subject of research. Moreover, it presents practical implications by suggesting that entrepreneurship education, combined with positive psychological capital development programs, could further enhance the business performance of young self-employed individuals.

Authors:   The Korean Career·Entrepreneurship & Business Association, Kim Jongah , Kim Daehong , Nam Jeongmin
Published: December 2024

This study is an empirical analysis of successful and unsuccessful companies from the perspective of investors. Accelerators and VCs were surveyed and asked to recall the most successful and unsuccessful companies after investment and answer the questionnaire. We sent 150 questionnaires, but received 68 responses from failed companies and 69 responses from successful companies, and conducted empirical analysis with 137 data. Using Wards, a hierarchical cluster analysis, the structure of the clusters was identified through a dendrogram, and using K-means cluster analysis, the failed companies were grouped into four clusters and the successful companies into five clusters. The four clusters of failed companies were characterised by, first, ‘lack of marketability verification and sales channels’, and second, ‘lack of patent and technology protection for products’. The third cluster was labelled ‘those who were in an existing market but failed to create a new market,’ and the fourth cluster was labelled ‘those who were unable to create a working prototype of their product and thus were unable to compete. The successful companies were divided into five clusters, the first being ‘those who beat the competition through marketing efficiency’, the second being ‘market-friendly’. The third cluster is ‘those that created new markets where there was no competition,’ and the fourth is ‘those that won with technological competitiveness. The fifth group, the most successful, is called the Market Expert Group. The most important takeaway from this is that market-friendly companies based on thorough market validation had the opportunity to grow faster than technology-based companies. This should serve as a reminder to startup entrepreneurs of the importance of market validation, as well as to startup incubators and mentors. The findings can be used pragmatically in future policy formulation to help startups grow through a sophisticated market validation process.

CVD prevention does not only mean effective fight against the existing cardiovascular risk factors, but also against their complications, including micro- and macrovascular ones. In relation to obesity, prediabetes and diabetes, we recognize a number of potential dangerous non-cardiovascular complications, such as neuropathy, nephropathy and retinopathy. The latter’s prevalence is even 30-40% and may appear in as many as 15% of patients with prediabetes. Not treated well might result in necessity of eye surgery or even vision loss. Fenofibrate has had a long history of evidence suggesting preventive role in primary and especially secondary prevention of retinopathy, what has been being investigated since the FIELD trial 19 years ago. In this Position Paper we have reviewed the current stage of knowledge on possible mechanisms, by which fenofibrate may contribute to retinopathy prevention, available data on safety and efficacy, to finally recommend administrating fenofibrate in prevention of this dangerous diabetic complication.
Lp(a) and thromboembolism: current state of knowledge and unsolved issues
Authors: Konieczyńska Małgorzata , Natorska Joanna , Ząbczyk Michał , Undas Anetta
Published: December 2024

Lipoprotein(a) [Lp(a)], a low-density lipoprotein-like particle containing apolipoprotein(a) [apo(a)], is a genetically determined independent risk factor for cardiovascular disease. Elevated Lp(a) levels, present in ~20% of Europeans, are linked to myocardial infarction, ischemic stroke, calcific aortic valve disease, and other cardiac events. Its role in venous thromboembolism (VTE) remains controversial despite shared arterial and venous mechanisms. Elevated Lp(a), particularly smaller apo(a) isoforms, exhibits antifibrinolytic effects by inhibiting plasminogen activation via interactions with plasminogen, tissue-type plasminogen activator, and fibrin. Prothrombotic mechanisms include increased plasminogen activator inhibitor-1 (PAI-1) production, formation of denser fibrin networks, platelet activation, enhanced oxidation of phospholipids, and tissue factor dysregulation. Emerging therapies targeting Lp(a) could reduce thromboembolic risks. This review summarizes Lp(a)'s prothrombotic and antifibrinolytic actions, clinical associations with thromboembolism, and the role of oxidized phospholipids in explaining discrepancies in VTE-related findings.

Authors: Tshuma Nothando , Mwanza Jason , Sibanda Emmanuel , Setoboli Tsepeso
Published: December 2024

The primary objective of this study was to develop an Analytical Model for Risk Mitigation and Growth in Manufacturing SMEs. Based on the study’s conceptual framework, data were collected via a questionnaire. The analysis was conducted using the random utility theory. The study finds cash flows, market penetration, investment, and diversification collectively explain the durable mitigation strategies implemented by manufacturing SMEs to enhance business growth. However, the probit model revealed that diversification was statistically insignificant at the 5% level of significance, suggesting that diversification is less important for bolstering the growth of manufacturing SMEs for manufacturing sector in Bulawayo. The study concludes that SMEs implementing durable mitigation strategies, which combine both informal and formal risk management practices, are more likely to experience business growth compared to those that follow either a formal risk management guideline or strictly an informal risk management practice. SMEs should prioritize improving cash flow management and making strategic investments to enhance growth. Given the statistical insignificance of diversification, SMEs should carefully assess the potential benefits and risks before pursuing diversification. Efforts should be made to increase market penetration through targeted marketing and expanding customer bases. Combining both informal and formal risk management practices can foster growth. SMEs should continuously monitor their risk mitigation strategies and adapt them based on changing market conditions and business environments.
The influence of digital out-of-home media on driver perception and driving: an integrative literature review
Authors: Lima Felisberto Lara , Casarin Vanessa
Published: December 2024

Out-of-home Media is constantly changing, incorporating new technologies, such as digital technology; this media is advancing faster than the research on the effects of it on consumers and the government in regulating it. In this sense, in order to contribute to advances in research and production within Information Design, we sought to investigate the influence of digital out-of-home (DOOH) media on driver perception and driving, striving to answer three main questions: What is the influence of DOOH Media on driving? What guidelines may be found in the scientific literature for managing these media in the landscape? What are the suggestions for future studies in this field? Research procedures involved an integrative literature review to uncover research and advances in the field of digital out-of-home (DOOH) media indexed in recognized databases which resulted in the full text analysis and synthesis of 32 studies, considering papers in scientific journals, conference papers, PhD thesis and research reports. The results pointed out that digital advertisements, especially animated ones, catch the attention of drivers and may compromise road safety. The distraction level may be affected depending on the luminance, brightness, and contrast levels and the number of words on the screen. Also, it was observed that young and senior drivers are more susceptible, and gender differences influence the perception and attention to the advertisements, although they are inconclusive. Studies recommend limiting words, controlling luminance, and adequately placing the advertisements for regulation.
Form over function: an analysis of Midjourney-generated infographics
Authors: C Klohn Reader Sara , Iacob Alis
Published: December 2024

Text-to-image generative models are a topic of great discussion in design. Seeking to understand the potential impact of these technologies on graphic design, this think piece paper presents preliminary insights from an explorative study that looked at 23 infographics generated by the popular platform Midjourney in 2023. The results indicated that, while the Midjourney outputs were at first glance plausible, upon closer examination these failed to solve a design problem. The repetitive layouts, the unintelligible textual elements and the disregard for purpose, context and audience, indicated that Midjourney is not currently producing infographics as understood by the design community. While not definitive, this study intends to contribute to the ongoing discussions in the wider field of AI and graphic design.

"Alter Christus": Edith Stein on the Liturgical Sources of "Bildung"
Authors: Lacy Travis
Published: December 2024

Edith Stein thought that a proper view of education, Bildung, should encompass not only a human person’s natural potencies and purpose, but their supernatural potencies as well. For her, the supernatural telos of a person’s education is that he or she become a unique image and icon of Christ. This transcendent goal requires similarly supernatural means to attain, and in this paper, the pivotal role played by the sacrament of the eucharist and the church’s liturgy more broadly in reaching that goal are examined, while further making methodological suggestions regarding the interpretation of Stein’s theological texts.Keywords: anthropology, Bildung, education, eucharist, grace,

Abstract. Detecting an unambiguous radar reflectivity signature is vital for investigating cloud-seeding impacts. The radar reflectivity change attributed to seeding depends on both the cloud conditions and the concentration of silver iodide (AgI) particles. In this study, the reflectivity change induced by glaciogenic seeding using different AgI particle concentrations is investigated under various cloud conditions using a 1D ice growth model coupled with an AgI nucleation parameterization. In addition, an algorithm is developed to estimate the minimum AgI particle concentration needed for a measurable glaciogenic cloud-seeding signature, assuming there is sufficient supercooled liquid water. The results show that the 1D model captures the ice growth habit compared to available observations and yields an unambiguous reflectivity change that is consistent with 3D model simulations and previous observational studies. Simulations indicate that seeding at a temperature of about −15 °C has the highest probability of detecting the radar seeding signature. This finding is consistent with the fact that the seeding temperature was about −15 °C or slightly warmer in most documented cases of unambiguous seeding signatures. Using the 1D model, 2500 numerical experiments are conducted, and the outputs are used to develop a parameterization to estimate the AgI particle concentration needed to detect an unambiguous seeding signature. Application of this parameterization to a real case suggests that seeding between −21 and −11 °C may possibly produce unambiguous seeding signatures and that seeding at about −15 °C requires the lowest AgI particle concentration. Seeding at warmer temperatures in precipitating clouds requires an extremely high amount of AgI and a very high content of supercooled liquid water. The results shown in this study deepen our understanding of the relationship between AgI particle concentration and radar seeding signatures under different cloud conditions. The parameterization can be used in operational seeding-based decision-making regarding the optimal amount of AgI dispersed.
Aerosol hygroscopicity over the southeast Atlantic Ocean during the biomass burning season – Part 1: From the perspective of scattering enhancement​​​​​​​

Published: December 2024

Abstract. Aerosol hygroscopicity plays a vital role in aerosol radiative forcing. One key parameter describing hygroscopicity is the scattering enhancement factor, f(RH), defined as the ratio of the scattering coefficient at humidified relative humidity (RH) to its dry value. Here, we utilize the f(80 %) from ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) 2016 and 2018 airborne measurements to investigate the hygroscopicity of aerosols, its vertical distribution, its relationship with chemical composition, and its sensitivity to organic aerosol (OA) hygroscopicity over the southeast Atlantic (SEA) Ocean during the biomass burning (BB) season. We found that aerosol hygroscopicity remains steady above 2 km, with a mean f(80 %) of 1.40 ± 0.17. Below 2 km, aerosol hygroscopicity increases with decreasing altitude, with a mean f(80 %) of 1.51 ± 0.22, consistent with higher values of BB aerosol hygroscopicity found in the literature. The hygroscopicity parameter of OA (κOA) is retrieved from the Mie model with a mean value of 0.11 ± 0.08, which is in the middle to upper range compared to the literature. Higher OA hygroscopicity is related to aerosols that are more aged, oxidized, and present at lower altitudes. The enhanced biomass burning aerosol (BBA) hygroscopicity at lower altitudes is mainly due to a lower OA fraction, increased sulfate fraction, and greater κOA at lower altitudes. We propose a parameterization that quantifies f(RH) with chemical composition and κOA based on Mie simulation of internally mixed OA–(NH4)2SO4–BC mixtures. The good agreement between the predictions and the ORACLES measurements implies that the aerosols in the SEA during the BB season can be largely represented by the OA–(NH4)2SO4–BC internal mixture with respect to the f(RH) prediction. The sensitivity of f(RH) to κOA indicates that applying a constant κOA is only suitable when the OA fraction is low and κOA shows limited variation. However, in situations deviating these two criteria, κOA can notably impact scattering coefficients and aerosol radiative effect; therefore, accounting for κOA variability is recommended.
Mid-Holocene ITCZ migration: impacts on Hadley cell dynamics and terrestrial hydroclimate
Authors: Bian Jianpu , Räisänen Jouni , Seppä Heikki
Published: December 2024

Abstract. This study investigates the multiple changes of the Hadley cell (HC) in response to the northward migration of Intertropical Convergence Zone (ITCZ) and their combined influence on terrestrial hydrological cycle during the mid-Holocene, using simulations from the PMIP4-CMIP6 archive. Our results show that orbital forcing increased radiative heating in the Northern Hemisphere, shifting the ITCZ northward by 0.2° and 0.3° as a multi-model mean using two different precipitation metrics, which is consistent with proxy evidence of a slight northward shift during the mid-Holocene. This migration primarily drives the northward movement of the inner HC edge, resulting in a contracted and weakened northern HC, while the southern HC expands and intensifies. Specifically, the northern HC width contracted by 1.1° and 0.5°, with strength reductions of 3.7 % and 4.1 %, while the southern HC expanded by 1.2° and 0.6° and strengthened by 2.9 % and 1.8 %, according to the two stream- function metrics. Enhanced moisture eddy fluxes are a major contributor to increased terrestrial precipitation in the Northern Hemisphere, particularly in monsoonal regions, while Southern Hemisphere precipitation decreased due to evaporation and dynamic terms. Moist static energy (MSE) budget analysis reveals that stronger rising motion significantly promotes vertical MSE advection over land in the Northern Hemisphere, enhancing moist convection and precipitation, while reduced rising motion weakens vertical MSE advection in the Southern Hemisphere, suppressing moist convection and precipitation. Regionally, ITCZ migration and associated HC changes alter climate patterns with reduced Northern Hemisphere terrestrial aridity and drylands contraction, while the Southern Hemisphere has enhanced aridity and drylands expansion. Multiple proxies support these findings, indicating wetter Northern Hemisphere conditions and a drier Southern Hemisphere, although inconsistencies remain in Australia’s aridity pattern. Our results highlight the complex interactions among ITCZ migration, Hadley cell dynamics, global hydrological cycle, and terrestrial aridity during the mid-Holocene.
Automatic tag detection in multimedia survey condition

Published: December 2024

Abstract. Recently, aquatic ecosystems have captured the interest of the international scientific community, spurring the development of new instruments and methodologies to explore, monitor, and preserve these environmental systems. In this context, the detection of shapes in shallow waters (either in submerged or semi-submerged scenarios) constitutes an intriguing research topic. Our investigation is framed within the multimedia photogrammetry domain, which aims to retrieve geometric information of static objects submerged or semi-submerged in a liquid (usually water), with one or more cameras placed outside the liquid itself. Performing a photogrammetric survey of objects in shallow waters with above-water cameras remains an open research field in the domain of Optics, presenting several theoretical problems and technical bottlenecks, starting with the study of refraction behaviour. Our goal is to develop an automatically applicable methodology to estimate a priori (and correct a posteriori) the effects of refraction on camera behaviour when capturing images of submerged or semi-submerged objects under certain conditions. We therefore tested the behaviour of the cameras in a controlled environment, through different depth levels and water motion conditions, and then elaborated a mathematical model of the optical distortion phenomenon encountered. Feature extraction presents many bottlenecks, mainly due to the particular optical conditions defined by multimedia acquisition and the eventual perturbations present if the liquid is in a condition of turbulence. This paper focuses on such technical problems, presenting part of the qualitative and quantitative results obtained at this stage of our research and the approach used to resolve some detection limitations.

Published: December 2024

Abstract. Traditionally, ship propellers are manufactured by sand-casting with slight oversizing and then milled or ground to the final shape. However, that manufacturing process, particularly in the production of small-diameter propellers (D < 5 m), can only partially be used competitively by the European industry in today´s market. A new method of manufacturing propellers is therefore needed.Additive manufacturing technology is already well established in the design and manufacture of marine systems. This article presents a means of monitoring the WAAM of propellers using image correlation methods. The GOM ARAMIS optical measurement system is used for its area measurement capability. The method is applied to two test series, one with flat steel plates and one with a ship propeller blade, using different welding materials.

Published: December 2024

Welding is a crucial technology in modern manufacturing processes, widely applied in automotive, oil refineries, and other industries. This study focuses on two standard welding techniques: Gas Metal Arc Welding (GMAW) and Shielded Metal Arc Welding (SMAW). GMAW uses argon gas as a shielding gas, and the ER70S-6 electrode has a 1.0 mm diameter, while SMAW employs the E7018 electrode with a 2.6 mm diameter. Both methods are tested on ASTM 106 Grade B steel, a commonly used material in various industries. The primary goal of this research is to evaluate the tensile strength of steel specimens welded using MIG and SMAW. The tensile strength of raw material, as well as the welded materials, is measured to assess the quality of the welds. The results show that the tensile strength of the raw material is 648.26 kgf/mm². After welding, the tensile strength for the MIG-welded material is 540.79 kgf/mm², while the SMAW-welded material achieves a higher tensile strength of 616.17 kgf/mm². These values highlight the significant difference in performance between the two welding techniques. SMAW welding provides the best joint quality among the two methods, with a tensile strength value of 616.17 kgf/mm². This study underscores the importance of selecting the appropriate welding technique based on the desired strength and application, with SMAW proving superior for this particular material. These findings contribute valuable insights into material technology and welding, offering a reference for future industrial applications.

Published: December 2024

Indonesia, an archipelago rich in cultural diversity, historical heritage, and stunning natural scenery, offers an extraordinary travel experience to visitors who make this country their vacation destination. Tourism in Indonesia plays an essential role in the domestic economy, contributing to Gross Domestic Product. With its abundant natural and cultural resources, North Sumatra has long been recognized as an attractive destination for foreign tourists. However, the tourism sector faces significant challenges related to fluctuations in the number of visits, mainly due to the impact of the COVID-19 pandemic, which has disrupted global travel patterns and caused considerable uncertainty in tourism forecasting. Therefore, predicting the number of tourist visits becomes crucial for effectively planning and managing tourist destinations. This research aims to compare the performance of two forecasting algorithms, SVM and linear regression, in predicting foreign tourist visits in North Sumatra using historical data from 2019 to 2023. The dataset was subjected to a preprocessing phase to ensure data cleanliness and consistency, focusing on key variables such as seasonal trends, external factors, and market dynamics. Both models were evaluated based on two commonly used accuracy metrics, MAPE and RMSE, to assess how well the models could predict actual tourist arrivals. The results of the study indicate that Linear Regression outperforms SVM in terms of prediction accuracy, with a MAPE of 42.40% and an RMSE of 6735.6, compared to SVM with a MAPE of 46.65% and an RMSE of 8020.42. These findings provide valuable insights for local government authorities and tourism industry stakeholders to enhance destination planning, resource allocation, and strategies to attract more foreign tourists in the post-pandemic era.
La producción de la sujeción desde el Poder y la potencia

Published: December 2024

A partir de la filosofía de Gilles Deleuze, en el presente artículo estudiaremos el proceso de sujeción, es decir, cómo cierto Poder reduce el potencial de los seres (humanos y otros), convirtiéndolos en súbditos de su ordenamiento autoritario. Tomando varios conceptos (plano de inmanencia, plano de consistencia, Cuerpo-Sin-Órganos) que atraviesan la ontología política deleuziana, analizaremos este proceso generador de impotencia señalando tres fases: cierre, sumisión y vigilancia. Explicaremos estos tres estadios (estratos) usando unos sencillos gráficos que facilitarán la comprensión y promoverán su aplicación a problemáticas actuales concretas. Finalmente, en las conclusiones, enarbolaremos el concepto animal (antagonista del sujeto) como expresión del CsO.
El pensamiento de Augusto Del Noce sobre la sociedad contemporánea y sus consecuencias políticas
Authors: Rivas Pedro
Published: December 2024

Augusto Del Noce es uno de los pensadores que más ha incidido en tratar de comprender la sociedad contemporánea en especial a partir del final de la Segunda Guerra Mundial. La originalidad de su análisis radica en especial en la explicación de la génesis de la sociedad presente y en su caracterización de la misma. Este trabajo pretende exponer sus ideas en relación con las de otros filósofos que coinciden en buena medida con él. A partir de tal exposición es posible sacar las consecuencias políticas de su pensamiento social.

استثمرت الباحثة موضوع البنية التركيبية في دراسة بنية الجملة الاسمية لآيات الأخبار المتناثرة في سورة البقرة، وذلك بهدف تحديد ملامح هذه البنية وما تكشف عنه من معانٍ ودلالات، كما استقرأت الباحثة مصطلحي البنية والتركيب عند علماء العرب والغرب قديما وحديثا، وفرقت بين مفهومي الخبر والقصة في القرآن، ووضعت من خلال تتبع المصطلحات حدا للخبر، قامت على أساسه بتحديد آيات الأخبار، واستخدمت الباحثة المنهج الوصفي منهجا لهذه الدراسة، فبدأت بجمع الآيات، وسرد تفاصيلها تاريخيا، وذكر القراءات المتصلة بالجانب النحوي فيها كونه مجال دراستها، ثم حللت بنيتها التركيبية مع ذكر أثرها في الدلالة قدر ما امكنها ذلك، فشكّل البحث نقطة التقاء بين عدد من العلوم، كعلم التفسير، والقراءات، والتاريخ، وعلم النحو وهو الأساس، ومن أبرز النتائج التي توصلت اليها الدراسة الاسبقية التاريخية لمصطلح الخبر على القصة، ووجود فرق واضح بينهما من حيث التكوين، كما أن سورة البقرة ضمت أربعة أخبار، اختلفت بنيتها التركيبية، واختلفت دلالاتها تبعا لذلك، وفي ضوء هذه النتائج توصي الباحثة بموضوع الدراسة التركيبية خصوصا في القرآن الكريم، لتحليل الآيات واستخراج الثروة اللغوية منها، ومعرفة الأوجه البلاغية فيها؛ لما له من أثر في فهم وتدبر القرآن الكريم، وتأكيد على اعجازه البياني، كما توصي الباحثة بجمع أخبار العهد النبوي العديدة ومتناثرة في سور القرآن الكريم، ودراستها وتحليل البنى فيها على كل مستويات اللغة: الصوتي والصرفي والنحوي.

Cucumber is one of the vines that is usually eaten directly or in processed form. The productivity of this cucumber crop is quite low. Cucumber production can be increased through intensification efforts. Intensification is a step taken to increase agricultural productivity through optimal utilisation of available land with various methods. One of them is the use of bat manure (Guano) fertiliser. Guano fertiliser comes from the process of weathering rocks and bat droppings that occur in natural caves containing nutrients N, P, and K. This research is to determine how effective the dose of Guano fertiliser is in increasing the productivity of organic cucumber. The research used the regular Randomised Group Design (RAK) method involving 7 treatments and 4 replications. The parameters observed were the dose of guano fertiliser, from no guano fertiliser; 2.5 t/ha; 5.0 t/ha; 7.5 t/ha; 10.0 t/ha; 12.5 t/ha; and 15.0 t/ha. Parameters that have been observed include number of leaves, plant height, fruit weight per hectare, fruit weight per plot, and fruit weight per sample plant. The data obtained will be calculated with the F test at 1 and 5% significance levels. If there is a significant difference, the next step is the BNT test at the 5% significance level. The optimal result of bat manure fertiliser dosage on baby cucumber productivity was found when using the highest dose, 15.0 t/ha, compared to other doses.
