Authors:   The Korea Academy of Case Management, Han Yeong-Nam , Kim Sang-Mi
Published: January 2025

This study aims to examine the impact of volunteer activity satisfaction on social capital in the Jeju region and to confirm whether community awareness plays a mediating role in the relationship between volunteer activity satisfaction and social capital. To achieve this, a theoretical discussion of the key factors related to volunteer activity satisfaction, social capital, and a sense of community was conducted, leading to the development of a research model and hypotheses. A structured questionnaire survey was administered to 344 adult volunteers engaged in social welfare facilities and organizations in Jeju Island, and multiple regression analysis was performed. The results revealed that satisfaction with volunteer activities significantly influences social capital, and the sense of community partially mediates the relationship between volunteer activity satisfaction and social capital. Based on these findings, the following recommendations are proposed: First, it is necessary to revise the Basic Law on Volunteer Activities. Second, diverse programs that can enhance the sense of community should be developed. Third, efforts are needed to foster changes in perception to promote the formation of social capital. It is hoped that this study's findings will stimulate practical and policy-oriented discussions for improving social capital.

O objetivo desta investigação foi analisar as características das estruturas agrícolas da agricultura familiar brasileira, em suas formas multiescalares, bem como seus aspectos de localização e especialização. Assim sendo, observou-se que a estrutura de produção, quer dizer, a composição dos produtos municipais da agricultura familiar no Brasil, tem apresentado semelhanças com a estrutura da produção da agricultura nacional. Evidências de especialização produtiva em produtos relacionados com commodities agrícolas apontam que a agricultura familiar também está se voltando para esses produtos. No entanto, nota-se uma redução da produção de culturas relacionadas com o mercado interno, com exceção da mandioca. Essa mudança pode afetar a política de segurança alimentar e nutricional no porvir, bem como impactar negativamente os preços dos alimentos no país.

Published: January 2025

Floods have been identified as one of the world's most common and widely distributed natural disasters over the last few decades. Floods' negative impacts could be significantly reduced if accurately predicted or forecasted in advance. Apart from large-scale spatiotemporal data and greater attention to data from the Internet of Things, the worldwide volume of digital data is increasing. Artificial intelligence plays a vital role in analyzing and developing the corresponding flood mitigation plan, flood prediction, or forecast. Machine learning (ML)-based models have recently received much attention due to their self-learning capabilities from data without incorporating any complex physical processes. This study provides a comprehensive review of ML approaches used in flood prediction, forecasting, and classification tasks, serving as a guide for future challenges. The importance and challenges of applying these techniques to flood prediction are discussed. Finally, recommendations and future directions of ML models in flood analysis are presented.
Los orígenes de la radiodifusión y los modelos de investigación del discurso radiofónico
Authors: Gavaldà Roca Josep V. , Mollá Furió Diego , Pellisser Rossell Nel·lo
Published: January 2025

La categorización del discurso radiofónico está determinada por los modelos estructurales sobre los que se articula el primer capítulo de la historia del broadcast, que concluye, finalizada la Segunda Guerra Mundial, con la irrupción de la televisión y la inmediata reestructuración del sistema mediático. Las estrategias de legitimación de la programación radiofónica, del vínculo pragmático que aspira a crear este nuevo dominio cultural, son esenciales en la evaluación del mapa disciplinar en el que se inscribe la fundamentación de la teoría de la radio. En la formulación de las distintas propuestas teóricas y metodológicas son determinantes las políticas de regulación, los modelos de negocio de la economía radiofónica y la función política y cultural reconocida a la radio. La investigación «administrativa» norteamericana construyó un modelo de análisis cuantitativo de aquel prodigioso broadcast esencial para el desarrollo de la audimetría mediática analógica y habilitó los primeros procedimientos para un análisis del like/dislike capital en el ámbito televisivo, primero, y, después, en el de las plataformas audiovisuales digitales y las redes sociales. El análisis cuantitativo sigue contando hoy, necesariamente, con los procedimientos tradicionales de la audimetría analógica, mientras prosigue la irresistible ascensión de la radio digital, que convierte en su ámbito aquella incierta medición en automático registro online. Los interrogantes suscitados por el análisis cualitativo desarrollado en tiempos aciagos, en Europa y en Estados Unidos, se mantienen vivos. El proceso de digitalización del broadcast, concluido en el caso de la televisión e inconcluso en el de la radio, la extensión del podcast y la multiplicación de los dispositivos de transmisión obligan a retomar una controversia que se dispone a cumplir un siglo.
IDENTIFYING THE IMPACT OF BUILDING CHARACTERISTICS ON INDOOR OVERHEATING: A SYSTEMATIC REVIEW
Authors: Keles Cagla , Hoque Simi
Published: January 2025

In recent years, indoor overheating in urban areas has become a significant phenomenon due to global warming and more frequent extreme heat events. Building characteristics are a decisive factor in identifying the indoor thermal resilience of buildings. The aim of this paper is to systematically review and analyze the impact of various building characteristics such as ventilation, envelope material, building age on indoor overheating, and to identify the knowledge gaps in our understanding of overheating in buildings. Through systematic literature review, 55 papers published between 2015–2023 were selected, and analyzed in terms of descriptive and qualitative approaches. Four building characteristics themes, which are building envelopes, ventilation, shading systems, and architectural & environmental attributes, were identified to reveal the various strengths, opportunities, and limitations of building characteristics. Then, gap analysis was provided concluding with recommendations and future research directions for mitigating overheating gleaned from a review of the current state of the research. Results revealed that although there are multiple strategies for reducing indoor overheating during extreme heat events, different design characteristics in different combinations need to be tested in various locations and climate conditions, particularly for future excessive heat events, to quantify their costs and benefits. At present, a holistic approach for identifying the building characteristics and their impact on indoor overheating does not exist. Moreover, more comprehensive research is needed to understand the impact of building characteristics in different urban environments in real-scale case studies. The study contributes to the understanding of the challenges and the research gap of existing literature regarding the impact of building characteristics on indoor overheating.

A Research on Character Feature Extraction for Computer Vision and Pattern Recognition
Authors: Wang Xiaoyuan , Wang Hongfei , Wang Jianping , Ge Jingjing , Dong Haiyan
Published: January 2025

Character feature extraction is a key area in computer vision and pattern recognition. Traditional methods often rely on manually designed extractors, which struggle with capturing complex structures and abstract features in character images, limiting their performance. The training and tuning of these models require considerable computational resources and time, reducing efficiency. This paper explores and compares various character feature extraction methods. It integrates two-dimensional wavelet decomposition with grid-based statistical and structural features. A detailed design of wavelet coarse and fine grid feature vectors is presented, starting with the construction and extraction of wavelet coarse grid feature vectors, followed by the finer grid feature vectors. The wavelet fine grid features demonstrate stronger specificity and discrimination than the coarse grid features. Experimental validation on 108 character samples yielded a 97.4% success rate, confirming the practicality and effectiveness of the proposed feature extraction method.

Published: January 2025

Growing Sri Lankan traditional rice (Oryza sativa L.) in the short day (Maha) season is crucial for the flowering initiation of most of the accessions. Masuran is a traditional rice variety with a high yielding potential including health-promoting attributes and premium price. This study was conducted to determine the effect of selected environmental factors of the season on the number of days to flowering (DF), plant height at flowering (PH) and selected yield components of two accessions of the ‘Masuran’ variety (Acc. No. 4132 and Acc. No. 5530). Planting was carried out on the 05th day of every month for a period of one year. Average daily rainfall (RF), temperature and photoperiod of each month were recorded. The effect of environmental factors on selected agronomic traits was analysed. Days to flowering, PH, Total Effective Tiller Number (TTN) and Number of Spikelets per First Panicle (NSFP) varied from 65 to 110 days, from 85.7 to 158 cm, from 3 to 8 and from 142 to 199 in Acc. No. 4132, respectively while those parameters varied from 60 to 89 days, from 80.3 to 170 cm, from 3 to 16, and from 119 to 283 in Acc. No. 5530, respectively during the experimental period. The analysis of the effect of photoperiod, rainfall and temperature of the first month of each planting revealed that the effect of photoperiod and temperature is significant on DF. The first month of each planting was observed as the photoperiod-sensitive phase of rice accessions. Correlation analysis for DF and NSFP resulted in a strong positive relationship suggesting a multi-factor environmental effect on NSFP of the variety, Masuran when it was grown throughout the year. The above results will be important in introducing a novel aspect for optimizing planting schedules and selecting suitable genotypes to enhance rice productivity under different environmental conditions.
Melanocytic Neuroectodermal Tumour of Infancy-A Rare Case Report
Authors: Beeram Ratna Kumari , Vamshidhar Busa , Seelam Sareen , Maloth Kotya Naik , Reddy Kundoor Vinay Kumar , Thakur Moni
Published: January 2025

Rationale:

Melanotic neuroectodermal tumour of infancy (MNTI) is an unusual, rapid growing, pigmented tumour of neural crestal origin that is seen in infants. It is more common in males with predilection for the maxilla and an unpredictable malignant potential. It constitutes a great challenge in diagnosis, treatment planning and prognosis.

Patient Concerns:

This is a case of MTNI in a 5-month-old female child, who presented to the Department of Oral and Maxillofacial Surgery with progressive swelling on the right side of the upper jaw over the last two weeks with ‘teeth floating appearance on imaging’.

Diagnosis:

There was significant extraoral diffuse swelling and facial asymmetry. Intraorally a well-defined mass noted on alveolar ridge of anterior maxilla and hard palate, crossing midline and associated with unerupted teeth. A subsequent contrast-enhanced computed tomography (CECT) scan and 3D CT scan revealed an expansile radiolucent lesion involving the right maxilla with destruction of cortical bone and displacement of primary central, lateral, canine and molar teeth, which appeared as a ‘free-floating teeth appearance’ in axial and coronal sections, confirmed by an open biopsy as Melanotic neuro-ectodermal tumour of infancy. Immunohistochemistry was used for precise diagnosis due to biopsy sample limitations and tumour variability.

Interventions:

Surgical resection was done after obtaining informed consent from the parents under general anaesthesia. The removal of unerupted primary central and lateral incisors, canine and molar teeth and also peripheral ostectomy was done as visible flecks were observed.

Outcome:

The postoperative period was uneventful. Regular follow-up after 26 months postoperatively showed acceptable healing with no portent of recurrence.

Take-away Lessons:

Early diagnosis and conservative surgical treatment and periodic follow-up postoperatively gives an excellent result with good prognosis.

Authors: Seyyedi Seyyed Amir , Ashrafi Mir Mehdi Seyyed , Rasmi Yousef , Marzban Amir Ali , Taram Saman
Published: January 2025

Introduction:

Impacted and semi-impacted third molar surgery can lead to considerable distress and discomfort in patients.

Aims:

The present study aimed to assess the changes in salivary levels of malondialdehyde (MDA) and total antioxidant capacity (TAC) after third molar surgery.

Materials and Methods:

In this study, 210 patients scheduled for third molar surgery were selected. Unstimulated whole saliva samples were collected from patients preoperatively and one week after the surgery, via the ‘spitting method’. The collected samples were immediately centrifuged and the supernatants were stored at −20°C until testing. The levels of MDA and TAC were measured with a spectrophotometer.

Results:

The results were presented as mean ± standard deviation and paired t-test was used to statistically analyse the changes in pre-operative and post-operative values of MDA and TAC. A decrease of mean salivary TAC (P = 0.031) and an increase of mean salivary MDA (P = 0.034) were detected postoperatively.

Discussion:

Following third molar surgery, the increase of mean salivary MDA and the decrease of mean salivary TAC were detected; however, these changes were not statistically significant.

Published: January 2025

Introduction:

Maxillofacial fractures cost the New Zealand Accident Compensation Corporation approximately NZ$ 70–80 million annually. We have previously reported on ethnic and age groups disproportionately affected by these injuries and the impact of the COVID-19 lockdowns. This study provides an analysis of the aetiologies contributing to maxillofacial fractures over a period of 11 years.

Materials and Methods:

Patients who were referred with a maxillofacial fracture to the Wellington Regional Plastic, Maxillofacial and Burns Unit from January 1, 2013 to December 31, 2023, were identified from our maxillofacial fracture database. The aetiology of injury was classified as interpersonal violence (IPV), fall, sport, road traffic accident (RTA), other or unknown. The number caused by each aetiology was correlated with year of injury to produce a trend over time.

Results:

A total of 2651 cases were identified during the study period. IPV was the most common aetiology, followed by fall, sport, RTA, other and unknown. The total number of injuries per year did not change significantly, nor did the number of injuries caused by sport, other or unknown aetiology. The number of injuries from IPV decreased by 3.9% per year, fall increased by 4.4% per year and RTA increased by 7.2% per year.

Discussion:

IPV remains the leading cause of maxillofacial fractures, although this is decreasing. The number of maxillofacial fractures caused by RTA is increasing. There is a sustained increase of maxillofacial fracture caused by falls, which especially affect the elderly, warranting further study of possible causes and preventative strategies.

Authors: Barbera Giorgio , Todaro Mattia , Saponaro Gianmarco , Rizzo Tommaso , Gasparini Giulio , Moro Alessandro
Published: January 2025

Introduction:

The tongue plays a crucial role in speech, swallow and sleep. It is the most common site of primary intraoral cancer. A fasciocutaneous free flap is the first reconstructive option after surgery.

Materials and Methods:

The aim of this study was to investigate the functional outcomes in patients treated with hemiglossectomy. We evaluated the objective tests and subjective assessments of swallowing, speech and sleep at 30 days after the surgery (T0) and at least 6 months after the end of the treatment (T1). We have implemented a battery of validated tools that comprehensively evaluate functional outcomes after resection of oral cancer, including speech, swallowing and head-and-neck-specific quality of life: MD Anderson Dysphagia Inventory (MDADI), Performance Status Scale-Head and Neck (PSS-HN) and Lazarus Tongue Range of Motion (ROM) Scale. Patients underwent objective tests such as videonasal endoscopic evaluation and magnetic resonance imaging. All patients were subjectively assessed with the Epworth Sleepiness Scale and underwent nocturnal polygraphy.

Results:

We treated six patients with advanced squamous cell carcinoma of the tongue; three received radial forearm flap and three received anterolateral thigh flap. Our study found that ROM, flap volume and defect volume are the most important characteristics for better MDADI, PSS-HN, Epworth score and respiratory disturbance index (RDI) on polygraphy.

Discussion:

Reconstruction of tongue cancer defects is challenging as the surgeon must consider adequate control of the tumour while also optimising residual functional capacity. The volume of the flap and ROM would seem to be the most important characteristics for improving the functional outcome.

Authors: Makkar Vidur , Pandurangi Aditya , Makkar Vidushi , Hani Ume , Mahadevaiah Mahesh , Pandurangi Swapna
Published: January 2025

Background:

Spinal cord injury (SCI) results in severe physical impairments and significant lifestyle disruptions, including paralysis, increased dependence on caregivers, and a tendency toward social isolation. These challenges deeply affect the psychological health and overall quality of life (QOL) of those impacted, especially in younger patients. Investigating the psychological and QOL outcomes in individuals with stable SCIs is crucial for developing tailored rehabilitation strategies.

Aim:

The study aimed to investigate the psychological health and QOL in patients with stable SCIs.

Materials and Methods:

This observational cross-sectional study involved patients with stable traumatic SCIs recruited through WhatsApp support groups from two major centers in India. Eligible participants were adults who were at least 1-year postinjury. Those with severe head injuries or nontraumatic spinal injuries were excluded. Participants provided sociodemographic information and injury history and completed assessments evaluating psychological health and QOL. Data were analyzed using IBM SPSS software, and statistical significance was determined through Chi-square tests.

Results:

Psychological distress was identified in 26.2% of the participants. Younger participants exhibited significantly poorer QOL in the psychological domain (P = 0.02). Employment status showed a significant association with the physical domain (P = 0.037) and overall QOL scores (P = 0.046). Socioeconomic status was significantly correlated with both the psychological (P = 0.004) and social domains (P = 0.009).

Conclusions:

The study underscores the considerable impact of SCI on psychological health and overall QOL, with younger individuals disproportionately affected. Healthcare providers should prioritize the integration of psychological support and counseling in SCI rehabilitation programs.

Authors: Pathave Hari , Poojary Sheetal
Published: January 2025

The dermatopathological features in morphea (localized scleroderma) and their clinicopathologic correlations are not well described in the literature. To describe dermatopathological changes of different types of morphea and to investigate the association between clinical and histopathological features. A total of 18 cases of morphea who attended our tertiary care center in the last four years were evaluated. We noted clinical characteristics of all patients and dermatopathological changes like the pattern of sclerosis, degree of inflammation, cell types and all epidermal-dermal, and appendageal changes. Clinicopathological correlation was performed to interpret the clinical significance of dermatopathological changes in various types of morphea. Morphea was most commonly noted in the third decade and females. A circumscribed plaque was the most common clinical presentation. Full-thickness pattern of sclerosis was significantly associated with various clinical outcomes. Basal pigmentation and a reduced number of appendages were noted in more than 80% of patients. All patients had various grades of inflammation. Severe and moderate-grade inflammation with eosinophils and plasma cells was associated with pruritus and/or pain. The limitations are small sample size and single-centered case series. The dermatopathological examination of morphea may help in better monitoring and treatment of patients, including patterns of sclerosis and grades of inflammation, and cell types in skin pathology reports will aid in proper and better clinical management.

Published: January 2025

This study aimed to determine the impact of cooperative learning strategy on students' chemistry achievement and retention in senior secondary schools within the Onueke Education Zone of Ebonyi State. To address this objective, three research questions and hypotheses were formulated. A quasi-experimental, non-equivalent control group design was adopted, involving two groups of students. A multi-stage sampling technique was employed to select a representative sample of 228 SSII chemistry students from six coeducational government-owned senior secondary schools. Initially, the target population of SSII students across 68 schools was stratified. Subsequently, six public secondary schools were simple randomly drawn from these strata. Finally, 3 schools from these six schools were randomly drawn and used as experimental group while the remaining 3 schools used as the control group. This combined sampling approach ensured both representativeness and controlled experimentation. The experimental group was exposed to cooperative learning strategy, while the control group received traditional lecture-based instruction. Findings revealed that cooperative learning significantly enhanced students' chemistry achievements and retention compared to the traditional lecture method. A chemistry achievement and retention test with a reliability coefficient of 0.97 was used to measure students' achievement and retention before and after treatment (pre/post-treatment). The data were analyzed using mean, standard deviation, and analysis of covariance (ANCOVA). The results indicated that the cooperative learning strategy was significantly more effective in enhancing students’ achievement and retention compared to the Lecture Teaching Method. This could be attributed to the student’s active engagement due to shared responsibility, peer support, social and communication skills in CLS than in LTM leading to increased motivation, development of critical thinking skills, immediate feedback, and diverse learning styles. It was also observed that within the cooperative learning strategy group, male students had higher mean achievement and retention scores than female students. The findings have important implications for educational practice, presenting cooperative learning as an effective strategy for improving chemistry teaching and learning.
Gender inequality and poverty in Akoka South West communities of Ondo State, Nigeria
Authors: Akinjole Elizabeth , Kudaisi Bosede , Fasoranti Mary M.
Published: January 2025

Poverty eradication has been a persistent global challenge throughout history. While approaches to addressing poverty have evolved, the fundamental issue remains unresolved. Studies have shown that there is a high prevalence of poverty among women, and the fundamental cause of this is gender inequality (SDG 5). Akoko Southwest Local Government Area communities are not exempted from this menace. This study looked at the nexus between gender inequality and poverty in Akoko Southwest Local Government Area communities, Ondo State. It also investigated the dimensions of poverty and areas of gender inequality among the sampled populations. The primary source of data made from self- administered copies of questionnaires was used to collect data from 200 respondents in five communities of the local government area. Of these, 175 questionnaires were valid and analysed. The sample population comprises both male and female adults. In addition, the Alkire-Foster methodology was utilised to analyse the dynamics of multidimensional poverty in the study area. We constructed the poverty index using the 2018 Nigerian Multidimensional Poverty indicators developed by UNDP Nigeria and NBS. We employed descriptive statistics and binary logistic regression. Household was used as the unit of analysis. The results showed high levels of gender inequality in all dimensions. On the multidimensionality of poverty, female-headed households experienced the incidence (88%) and intensity (60%) of poverty while their male counterparts experienced the incidence (54%) and intensity (42%) of poverty. The outcome also showed that female-headed households were more deprived in terms of education, health, living conditions, unemployment, and asset ownership. The binary logistic regression analysis showed there is a positive relationship between the female-headed household and poverty in the study area with a p-value less than 0.1, which suggests that there is a higher prevalence of poverty in female-headed households than in male-headed households. Overall, the findings revealed that gender, age, and education of household heads significantly contribute to the poverty status of the households. The study concludes that poverty in Akoko-Southwest LGA communities is both a symptom and cause of gender inequality as females are more impoverished due to deprivation in areas such as education, nutrition, living standards, and employment.
Ensuring continuity in the formation of concepts in sciences studies in general education
Authors: BOCANCEA Viorel
Published: January 2025

The principle of systematization and continuity of knowledge highlights the fact that the subject of study, the content of the educational disciplines must be structured in units of knowledge, ordered from a logical, scientific and psycho-pedagogical point of view. When studying the subjects of Science, Physics, Chemistry, Biology, Geography, the formation of the main groups of concepts takes place. Ensuring the continuity of the process of formation of scientific concepts takes place, respecting certain conditions. The article proposes techniques to meet these conditions: concept formation map and generalized concept study plans.

Published: January 2025

The sulfate anion, possessing a tetrahedral geometry, is a versatile polydentate ligand in the engineering of extended network structures. Following the reaction of zinc and cadmium sulfates with the azine ligands 3-bphz, 4-bphz, 3-bpmhz and 4-bpmhz, a series of complex compounds were obtained, six of which showed a polymeric structure. The aim of the research is to identify the synthesis conditions and the precursors used in the reaction that lead to the formation of three-dimensional coordination networks. The simple synthetic conditions allowed us to follow the evolution of coordination networks.

The study investigates the relationship between the mercury (Hg) content in the muscles of the perch Perca fluviatilis L., 1758 from different areas of the Rybinsk Reservoir including tail-water of the Uglich hydroelectric power plant, which differ in their physico-chemical characteristics, and the length of the fish. The measurement of Hg was carried out using the atomic absorption method on a RA-915+ mercury analyzer with the PYRO prefix (Lumex), without any preliminary sample preparation. The detection limits for Hg concentrations in biological samples on this device range from 0.0005 to 2.0000 mg/kg. Average metal concentrations ranged from 0.04 to 0.87 mg/kg of wet weight for fish with an average length of 2.2–45.0 cm, and differed by reservoir sections. The magnitude of effect of the fish length on the metal content in fish muscles was determined by the slope of the regression line, which indicates the rate of Hg accumulation, and the intercept of the line on the Y-axis representing the baseline level of Hg in organisms at the beginning of the food chain for each specified group. It was found that the maximum intensity of Hg accumulation is attained in the perch of up to 10 cm long and then significantly decreased in larger fishes, variably depending on the sampling area within the Rybinsk Reservoir.

Strawberries are sensitive to pathogens attack. Therefore, they require specific phytosanitary control measures. Antagonistic microorganisms, such as the biological control agents, have been suggested as an alternative method to prevent various infections. The aim of this work was to select beneficial yeasts and bacterial strains with inhibitory potential against the phytopathogenic fungus Botrytis cinerea, that causes gray mold. Certain in vitro tests were performed to identify the biocontrol mechanisms of action. Moreover, the presence of coliform bacteria was also evaluated on the strawberry fruits grown in organic system. Two yeast strains, Saccharomyces cerevisiae L30b and Metschnikowia pulcherrima sa5, and other six bacterial strains, Bacillus subtilis A4, Pseudomonas chlororaphis RG, P. fluorescens Rcp2, R2.1d and 79.3 and Serratia plymuthica Ps33, were tested in vitro for the production of diffusible and volatile compounds with antifungal effect. The results highlighted Pseudomonas fluorescens R2.1d strain which had the best efficacy on inhibiting the pathogenic mycelium growth. This strain released both diffusible and volatile antagonistic compounds against gray mold caused by B. cinerea, with as efficacy of 68.9% and 88.9%, respectively. The strawberries surface microbiota was evaluated on fruits collected from an ecological production system, having different technological option as experimental variants. The lowest microbial load of coliform bacilli was shown on the strawberry fruits collected from the matted row variant, covered with black foil mulch, compared to the other technological option of the ecological production system.

This paper presents the results of the research carried out in pedoclimatic conditions at SCDA Pitești regarding the influence of tillage systems on the economic efficiency of the pea crop in the agricultural year 2023. The determination of economic efficiency was carried out according to the average physical yield for the year 2023, the yield value and the total cost of yield (cost of mechanical works + cost of materials). The pea yield in 2023 depending on the pedoameliorative and basic soil works varied from 1581 kg/ha to 3561 kg/ha. In the conventional deep plowed scarified soil system, the physical yield recorded an average value of 3561 kg/ha with a yield value of 7122 lei/ha. The yield cost was 4926 lei/ha, the net income 2196 lei/ha, obtaining a profitability value of 45%. In the variants with nonscarified soil, deep plowed, the physical yield was 3401 kg/ha with a value yield of 6802 lei/ha. The yield cost had the same values as in the variants with scarified soil. The net income recorded was 1876 lei/ha with a profitability of 39%. The conservative system sown directly, in the variants with scarified soil recorded an average yield of 1693 kg/ha and a yield worth of 3386 lei/ha. Regarding the yield cost, the price was 4679 lei/ha. Net income and profitability recorded negative values of -1293 lei/ha, respectively -28%. In the variants with nonscarified soil, the average physical yield was 1581 kg/ha, with an average value yield of 3162 lei/ha. The yield cost amounted to the same value as in the variants with scarified soil. The recorded net income was -1518 lei/ha, and the profitability -32%.

Penelitian ini bertujuan untuk mengetahui aktivitas strategi presemtasi diri ganjar pranowo melalui media sosial instagram @ganjar_pranowo. Subjek penelitian adalah akun instagram Ganjar Pranowo yaitu @ganjar_pranowo. Objek penelitian berfokus kepada postingan Ganjar Pranowo. Alat analisis yang digunakan adalah teknik validitas data berupa triangulasi teori. Hasil penelitian bahwa melalui akun intagram Ganjar Pranowo (@ganjar_pranowo) menggunakan strategi impression management yaitu ingratiation (supaya disenangi), intimidation (strategi intimidasi agar disegani), self-promotion (strategi promosi diri agar dipercaya atas kemampuannya), exemplification (strategi mencontohkan diri agar terlihat mulia). Ganjar Pranowo tidak menggunakan strategi supplication. Alasan tersebut digunakan karena jika menggunakannya strategi supplification Ganjar Pranowo akan nampak seperti gubernur yang tidak mampu mengemban tugasnya dan berdampak negatif terhadap performanya dibenak masyarakat, maka tentunya strategi tersebut dihindari untuk memberikan kesan baik di benak publik.
