BACKGROUND:

The quality of nurses' professional life is at stake in crises such as COVID-19. Empowerment helps employees perform better and advance the goals of the organization. This study aimed to investigate the relationship between empowerment and the quality of nurses' professional life during the outbreak of COVID-19.

MATERIALS AND METHODS:

The current cross-sectional study was conducted in 2021 in the hospitals of Babol University of Medical Sciences with the participation of 200 nurses providing care for COVID-19 patients who were included in the study by convenience sampling method. Data collection tools included the Empowerment Questionnaire (Leader Empowerment Behaviors Scale, Structural Empowerment, and Psychological Empowerment) and the Professional Quality of Life Questionnaire. SPSS software version 23 was used to analyze the data. Multiple linear regressions were used to investigate the relationship between empowerment and quality of professional life.

RESULTS:

In the majority of nurses, compassion satisfaction 140 (70%), burnout 172 (86%), and compassion fatigue 126 (63%) were at moderate level. A significant relationship was found between compassion satisfaction and Leader Empowerment (R = 0.54, P = .001), Psychological Empowerment (R = 0.55, P = .001), and Structural Empowerment (R = 0.42, P = .001) and Compassion Fatigue and Leader Empowerment (R = 0.35, P = .001), psychological empowerment (R = 0.42, P = .001), and structural empowerment (R = 0.49, P = .001).

CONCLUSION:

Nursing managers' attention to empowerment strategies in crises such as COVID-19 can improve compassion satisfaction and reduce compassion fatigue in nurses. It is also necessary to implement policies and guidelines for the development of psychosocial support to health promotion of the workplace, education, informing, and empowering nurses.

Authors: Sabahi Azam , Jalali Samaneh , Ameri Fatemeh , Garavand Ali , Negahban Ahmad
Published: October 2023

Type 2 diabetes, as one of the most common chronic diseases, requires ongoing management and support from the patient; therefore, patient participation and self-management play a pivotal role in controlling and preventing this disease. The increasing use of smartphones has provided a good opportunity for controlling and managing patients with type 2 diabetes. This study aimed to investigate the effect of mobile health on the self-management of patients with type 2 diabetes in Iran. A systematic review study was conducted from 2010 to 2021. Searches in Persian and English scientific databases, IranDoc, MagIran, SID Web of science, and PubMed, were performed using keywords such as diabetes and mobile health. The process of reviewing and selecting articles based on inclusion and exclusion criteria was performed by two researchers independently. The study evaluation was performed by using a standard tool. After selecting articles, data extraction was performed using a data extraction form. Data analysis was performed with a content analysis approach. Finally, 23 articles were included from the 7767 articles found in the initial search stage, which examined patients' self-care in 11 areas using mobile health. Fourteen studies (61%) considered mobile health to be effective in increasing hemoglobin control. Other studies also found the use of mobile health in increasing adherence to exercise (n = 10), increasing adherence to medication (n = 9), increasing adherence to diet (n = 11), increasing care for diabetic foot ulcers (n = 8), increasing self-efficacy and empowerment (n = 5), increasing cholesterol control (n = 4), increasing awareness and attitude (n = 4), increasing control of insulin dose (n = 2), increasing adherence to education (n = 1), and increasing control of blood urea (n = 1), which were considered effective. The use of m-health effectively controls the disease and promotes self-management in type 2 diabetic patients. Considering the high cost of diabetes treatment, policymakers should implement appropriate interventions and strategies in the field of using mobile health to improve adherence to self-management of the disease.

Published: October 2023

Abstract

Aim:

The bidirectional relationship between type 1 diabetes mellitus (T1DM) and inflammatory periodontal disease (PD) is globally recognized. However, oral health components are often given lower priority, and studies related to knowledge and the bidirectional association are limited. This study assesses the knowledge and perceptions of PD and its associated risk factors among T1DM patients and/or their parents.

Materials and Methods:

Patients under 18 with T1DM at Universiti Teknologi MARA and Universiti Malaya were invited to participate. Structured interviews were conducted to assess participants’ knowledge and perceptions of T1DM, and statistical analysis was performed to examine their associations using Pearson’s chi-squared test and Fisher’s exact test.

Results:

A total of 113 T1DM patients, with a mean age of 11.4 ± 4, completed the interviews. Poor knowledge was observed among parents and T1DM patients (P-value = 0.007) and those who exercised regularly (P-value = 0.047). A significant association with good perception was found among individuals with uncontrolled HbA1c levels (P-value = 0.0018) and those experiencing bleeding symptoms (P-value = 0.021).

Conclusions:

The study highlights the importance of increasing awareness, a key factor in improving oral health knowledge. Interestingly, despite poor control of clinical parameters, the population displayed good perception, suggesting a potential lack of understanding regarding disease control.

Published: October 2023

Abstract

Aim:

The aim of this retrospective cohort study was to determine the risk factors associated with the occurrence of dental caries increments in Thai dental patients.

Materials and Methods:

The dental chart records of 500 patients who visited the Department of Advanced General Dentistry, Mahidol University during 2003–2013 were included in this research. Risk factors such as age, gender, medical history, marital status, routine oral checkup, oral appliance usage, initial and final records of decayed (DT)-missing-filled (DMF-T), dental history of tooth extraction due to caries, xerostomia, presence of visible plaque, presence of interproximal restoration, and caries risk level were retrieved from dental records. Cox proportional hazard regression model was used to determine the association of caries risk factors and new dental caries increments.

Results:

The results indicated that the rate of incidence of new dental caries was 2.1 per 100 person-month. In the multivariate hazard model, past caries experience in more than three teeth (adjusted hazard ratio: 2.29, 95%CI: 1.53–3.44) and xerostomia (adjusted hazard ratio: 4.47, 95%CI: 1.82–10.98) were independent risk factors of dental caries increments. Other factors, such as demographic data, physical factors, clinical factors, and other contributing factors, were not associated with the incidence of new dental caries.

Conclusion:

The presence of past caries experience and xerostomia were predictors of the occurrence of new dental caries.

Published: October 2023

Abstract

Aim:

To study the masticatory efficacy and oral health-related quality of life (OHRQoL) of participants wearing a mandibular overdenture retained by an immediate loading single implant with different occlusal tooth forms.

Materials and Methods:

For this nonrandomized controlled trial study, 27 edentulous participants were selected and randomly divided into three groups (n = 9) based on occlusal tooth forms of the mandibular implant overdenture (MIOD). Group I: participants received an MIOD with an anatomical tooth form; Group II: participants received an MIOD with a semianatomical tooth form; and Group III: participants received an MIOD with a nonanatomical tooth form. For each participant, a single implant (screw root form) was inserted into the midline of the mandibular ridge to support the MIOD. For each group, the masticatory efficiency was evaluated after 3 months, and the OHRQoL of the participants was evaluated after 3 and 6 months. One-way ANOVA and post hoc Tukey’s test were used for data analysis (P < 0.05).

Results:

The masticatory efficiency of the anatomic and semianatomic tooth forms was higher than that of the nonanatomic (P < 0.05). Moreover, the improvement in the participants’ OHRQoL in the anatomic group was more significant than that of other groups (P < 0.05).

Conclusion:

There was a greater improvement in masticatory efficiency and participants’ OHRQoL when fitted with an anatomic tooth form mandibular overdenture retained by an immediate loading single implant than with a semianatomic or nonanatomic tooth form.

Is Methyl Methacrylate Fixator Reliable for the Treatment of Gartland Type IV Supracondylar Fractures?
Authors: Ciftci S , Safali S , Ergin M , Özdemir A , Acar MA
Published: October 2023

ABSTRACT

Background:

In childhood supracondylar fractures of the humerus, fixation with percutaneous Kirschner wire is the standard treatment. In the case of irreducible–unstable fractures, these can be defined as fractures in which reduction is not well-achieved or in which fixation cannot be achieved with the K-wire. Intraoperative management of these types of fractures may be difficult. Treatment with a methyl methacrylate fixator consisting of K-wire and methyl methacrylate cement, as defined by the senior author of the article, may be a good option for Gartland type IV supracondylar humeral fractures where the fracture is unstable in flexion and extension due to complete periosteal tearing.

Materials and Methods:

The short-term and mid-term results of 27 patients between the ages of 4–12 with Gartland type IV supracondylar fracture of the humerus treated with methyl methacrylate fixation were reviewed. The patients were scored in terms of function and cosmetic satisfaction.

Results:

A total of 19 of the 27 patients treated with the methyl methacrylate fixator had full elbow motion function and rated the outcome of the treatment as excellent, which was judged by orthopedic surgeons on the basis of Flynn’s criteria. Six patients had nearly full elbow motion and evaluated their recovery outcome as good. Two patients reported nearly full range of motion (ROM) and evaluated the method as moderate in terms of treatment.

Discussion:

Treatment with the methyl methacrylate fixation method is an inexpensive method that allows early joint mobilization, provides strong biomechanical stability, ensures good outcomes, and should be considered in the treatment of irreducible and unstable supracondylar fractures of the humerus.
Can Gallbladder Wall Thickness and Systemic Inflammatory Index Values Predict the Possibility of Conversion from Laparoscopy to Open Surgery?
Authors: Balbaloglu H , Tasdoven I
Published: October 2023

ABSTRACT

Background/Objective:

This study aims to develop an objective marker that predicts the risk of conversion from laparoscopy to open surgery using gallbladder wall thickness and inflammatory index values.

Materials and Methods:

A total of 2,920 cholecystectomy patients were screened, including those whose operations were converted to open and those who underwent laparoscopy. A total of 700 cholecystectomy patients who met the study criteria were included in the study. The same team of surgeons performed all operations. The conversion probability from laparoscopic to open cholecystectomy was calculated using the ratio obtained by evaluating inflammatory markers and gallbladder wall thickness (K). The preoperative complete blood count and abdominal ultrasound data of the patients were obtained from our university patient registry system.

Results:

Age, neutrophil count, gallbladder wall thickness, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), KxNLR, and KxPLR values were all significantly higher in the conversion from laparoscopy to open surgery group compared with the laparoscopic cholecystectomy group. According to the ROC analysis performed on the gallbladder wall thickness values according to the probability of conversion to open surgery, the cutoff value was determined as >3 mm. Gallbladder wall thickness >KxPLR >KxNLR was defined as the diagnostic value order according to the area under the curve.

Conclusions:

The results of this study showed that gallbladder wall thickness effectively determines the probability of conversion from laparoscopy to open cholecystectomy and multiplying the gallbladder wall thickness (mm) by NLR increased the sensitivity.

Authors: Yilmaz D , Baykan O , Baykan H
Published: October 2023

ABSTRACT

Objective:

Thyroid dysfunctions are among the most common endocrine disorders in society. An increase or decrease in thyroid hormone levels may present with neurological and/or psychiatric symptoms. In this study, we aimed both to determine the prevalence of this disorder in our region by determining the frequency of thyroid dysfunction in patients diagnosed with major depressive disorder in our outpatient clinic and to raise awareness during the evaluation process of patients.

Material and Method:

Thyroid-stimulating hormone (TSH) levels of 1035 patients diagnosed with major depressive disorder in our hospital between January 2020 and January 2022 were retrospectively scanned from the hospital information management system and those outside the reference ranges (0.38–5.33 mIU/L) were determined.

Results:

It was observed that TSH was not within the reference ranges in approximately 7% of the patients diagnosed with depressive disorder. 1035 patients were included in the study. When the blood results of 1035 patients included in the study were examined retrospectively, 32 of them had TSH values below 0.38 mIU/L. TSH value was found to be above 5.33 mIU/L in 44 of them.

Conclusion:

Obtained data have shown that thyroid dysfunctions can be encountered frequently in patients presenting with depressive complaints. It is thought that the evaluation of patients with depressive complaints in terms of thyroid dysfunction, and the treatment of the underlying thyroid dysfunction will contribute to the regression of psychiatric symptoms.

Authors: Wang J , Chen W , Lai Y
Published: October 2023

ABSTRACT

Background:

Epilepsy is a relatively common childhood neurological disease. Children with epilepsy need to take precautions to minimize seizure damage in order to adapt to seizures and manage them.

Aim:

The current study aimed to evaluate the feasibility and effects of a comprehensive nursing program for children with epilepsy to reduce children’s symptoms of epilepsy.

Subject and Methods:

Participants were children suffering from epilepsy between 2019 and 2021 at Ningbo Women and Children’s Hospital. Seventy children were included in a randomized controlled trial with a comprehensive nursing group (CNG) and an active control group (ACG). Measurements were assessed pre- and post-intervention and at a one- and three-month follow-ups. Children in the CNG learned and practiced the strategies related to the comprehensive nursing intervention. The outcomes were anxiety and depression.

Results:

The results showed that anxiety and depression scores were significantly lower in the CNG than the ACG at 1 and 3 months after intervention (P < 0.05). According to the feasibility results, whereas most participants believed that the program was informative and meaningful, a minority reported that it was time-consuming.

Conclusion:

The intervention has the potential to support children with epilepsy. The program is easily accessible, cost-effective and could be implemented in epilepsy care rehabilitation.

Authors: Rathinakumar Nivethia K. , Nishanthi Anandabaskar , Manickam Shanthi
Published: October 2023

Aim:

To assess the perception and practices on COVID-19 vaccination and to determine the predictors of booster dose acceptability among health-care workers (HCWs) in South India.

Materials and Methods:

We conducted an anonymous cross-sectional survey on the perception and practices on COVID-19 vaccination and booster dose acceptability among the HCWs in South India. We prepared an online self-administered validated questionnaire, and the Google form link to it was circulated from March 28, 2022 to April 27, 2022, in the social media groups of the HCWs. We used binary logistic regression to identify the predictors of booster dose acceptability among HCWs.

Results:

Overall, we obtained 572 valid responses, of which the majority were from paramedical workers compared to doctors. Most of the respondents were unmarried females aged <30 years. Around 31.6% had been previously diagnosed with COVID-19. About 97.9%, 88.8%, and 12.6% of the participants have taken the first, second, and booster doses of the COVID-19 vaccine, respectively. Among the respondents, 19.7% refused to take the booster dose. The main reason for booster dose refusal is the belief that two doses of the COVID-19 vaccine are sufficient to confer disease protection. Believing vaccination to be one of the most effective measures in COVID-19 prevention and being doctors by profession were the chief predictors of booster dose acceptance among HCWs.

Conclusion:

While the uptake of the primary COVID-19 vaccination series was commendable among Indian HCWs, booster dose was taken only by a minority of them.

Authors: Abdulah Deldar Morad , Hasan Jinan Nori , Hasan Sheelan Bapir
Published: October 2023

Objectives:

We examined the effectiveness of combining Vitamin D supplementation with calcium on maternal and neonatal outcomes, as opposed to using Vitamin D supplements alone.

Materials and Methods:

Pregnant women in their third trimester were divided into two groups. The control group received a daily dose of 1000 IU of Vitamin D, but, the experimental group received a combined daily dosage of 1000 IU of Vitamin D and 500 mg of calcium, until delivery.

Results:

The women in the Vitamin D + calcium group were less likely to develop gestational diabetes (2.78%; vs. 19.51%; P = 0.0318), preeclampsia (2.78% vs. 26.83%; P = 0.004), newly onset gestational hypertension (11.11% vs. 46.34%; P = 0.001), proteinuria (5.56% vs. 39.02%; P = 0.0004), and impaired glucose tolerance (2.78% vs. 21.95%; P = 0.0163) and had lower blood pressure at 20th and 39th weeks of gestation. The newborns in the Vitamin D + calcium group were less likely to experience low birth weight (5.71% vs. 31.58%; P = 0.0066), low birth length (5.71% vs. 44.74%; P = 0.0007), were less likely to be admitted to the neonatal intensive care unit (14.29% vs. 42.11%; P = 0.0105), have a larger head circumference (35.00 vs. 33.63; P < 0.0001), longer gestational age at birth (40.0 vs. 37.56 weeks; P < 0.0001), and higher APGAR scores (9.58 vs. 6.31; P < 0.0001.) compared to Vitamin D group, respectively.

Conclusions:

Taking Vitamin D and calcium by pregnant women in the third trimester is an effective treatment to decrease maternal, fetal, and neonatal outcomes.

Published: October 2023

In many parts of the world, heart disease is the leading cause of mortality diagnosis is critical Towards Efficient Medical Care and prevention of heart attacks and other cardiac events. Deep learning algorithms have shown promise in accurately predicting heart disease based on medical data, including electrocardiograms (ECGs) and other health metrics. With this abstract, Specifically, we advocate for deep learning algorithm in accordance with CNNs for Deep Learning effective heart disease prediction. The proposed method uses a combination of ECG signals, demographic data, and clinical measurements Identifying risk factors for cardiovascular disease in patients. The proposed CNN-based model includes several layers, such as convolutional ones, pooling ones, and fully connected ones. The model takes input in the form of ECG signals, along with demographic data and clinical measurements, and uses convolutional layers to get features out of raw data. To lessen the effect of this, pooling layers are dimensionality of the extracted features, while layers that are already completely linked to estimate the risk of cardiovascular disease based on the extracted features. Training and evaluating the suggested model, We consulted a broad pool of ECG signals together with patient clinical data, both with and without heart disease. Training and test sets were created from the dataset testing arrays, and the prototype was trained using backpropagation and stochastic gradient descent. The model was evaluated using standard quantitative indicators such the F1 score, recall rate, and accuracy rate. The outcomes of experiments demonstrate the suggested CNN-based model achieves high accuracy in predicting heart disease, with an overall accuracy of over 90%. The model also outperforms several alternatives to classical techniques for heart disease prediction, including the more conventional forms of AI algorithms different forms of deep learning models. In conclusion, the proposed deep learning algorithm based on CNNs shows great potential for effective heart disease prediction. The model can be integrated into healthcare systems to provide accurate and timely diagnosis and treatment for patients with heart disease. Further research can be done to optimize the model's performance and test its effectiveness on different patient populations.
New structure on the quantum alcove model with applications to representation theory and Schubert calculus
Authors: Kouno Takafumi , Lenart Cristian , Naito Satoshi
Published: October 2023

The quantum alcove model associated to a dominant weight plays an important role in many branches of mathematics, such as combinatorial representation theory, the theory of Macdonald polynomials, and Schubert calculus. For a dominant weight, it is proved by Lenart–Lubovsky that the quantum alcove model does not depend on the choice of a reduced alcove path, which is a shortest path of alcoves from the fundamental one to its translation by the given dominant weight. This is established through quantum Yang–Baxter moves, which biject the objects of the models associated to two such alcove paths, and can be viewed as a generalization of jeu de taquin slides to arbitrary root systems. The purpose of this paper is to give a generalization of quantum Yang–Baxter moves to the quantum alcove model corresponding to an arbitrary weight, which was used to express a general Chevalley formula for the equivariant

K

-group of semi-infinite flag manifolds. The generalized quantum Yang–Baxter moves give rise to a “sijection” (bijection between signed sets), and are shown to preserve certain important statistics, including weights and heights. As an application, we prove that the generating function of these statistics does not depend on the choice of a reduced alcove path. Also, we obtain an identity for the graded characters of Demazure submodules of level-zero extremal weight modules over a quantum affine algebra, which can be thought of as a representation-theoretic analogue of the mentioned Chevalley formula.
Vehicle Mass and Road Gradient Estimation by Series Kalman Filter and 3-Axis Accelerometer for Real-World Application
Authors: Ma He , Milton Gareth , Truscott Anthony , Hou Sichen , Fung Alex
Published: October 2023

For modern vehicle development, on-board vehicle Mass and road Gradient Estimation (MGE) can offer great benefit to many sub-systems on the vehicle, such as vehicle control system, transmission control system, and active safety system etc. However, there are still several challenges that need to be solved. Firstly, thanks to good accuracy, reliability, and robustness, regression analysis-based approaches: Recursive Least Squares (RLS) and Kalman Filter (KF) are very popular for MGE, but the trade-off between estimator’s accuracy and converge time is challenging. Furthermore, depending on vehicle and powertrain types, the implementation of MGE function could be very different. It is desired to have a structured approach for various vehicle applications’ MGE development. Lastly, good reliability of MGE does not always satisfy for complicated real-world driving maneuvers and road conditions.

This paper introduced a mature MGE development approach which utilizes an innovative Series Kalman Filter (S-KF) structure with a 3-axis accelerometer to address the challenges above, leading to the demonstration on 3 different types of vehicles with different powertrain applications: a truck with Internal Combustion Engine (ICE) and Automated Manual Transmission (AMT) gearbox, a mid-size Plug-in Hybrid Electric Vehicle (PHEV) SUV, and an A-segment Battery Electric Vehicles (BEV) mini car. They are tested under wide range real-world driving maneuvers and road conditions. Moreover, to improve the converge time whilst keeping the same accuracy of MGE, several dedicated designed engineering features are implemented and introduced in this paper. The vehicle-based experimental result and structured development approach showed good performance and maturity of the production oriented MGE, and good efficiency and flexibility to adapt it to various applications.

Estimation of the State of Health of the Proton Exchange Membrane Fuel
Cell
Authors: Fan Lei , Zhou Su , Zhao Peng , Gao Jianhua
Published: October 2023

To study the state of health (SOH) of the proton exchange membrane fuel cell
(PEMFC), a novel hybrid method combining the advantages of both the model-based
and data-driven methods is proposed. Firstly, the model-based method is proposed
based on the voltage degradation model to estimate the variation trend, and
three parameters reflecting the performance degradation are selected. Secondly,
the data-driven (long short-term memory (LSTM)) method is presented to estimate
the variation fluctuation. Moreover, the core step of the hybrid method is
returning the results of the LSTM method to the power degradation model as the
“observation” and modifying related parameters to improve the estimation
accuracy. Finally, the sliding window method is applied to solve the problem of
the data increase with the increase of the operating time. The results show that
the power estimation is better than the current estimation for the SOH
estimation. The estimation accuracy of the hybrid method dependent on the model
accuracy, the amount of experimental data, and the data preprocessing is higher
than that of the model-based method. The power estimation accuracy by the hybrid
method of the estimation window length 5 h, 10 h, and 20 h are 99.2%, 98.68%,
and 96.87%, respectively.

Authors: Lou Diming , Zhao Yinghua , Fang Liang , Zhuang Caihua
Published: October 2023

Reinforcement learning is a promising approach to solve the energy management for hybrid electric vehicles. In this paper, based on the DQN (Deep Q-Network) reinforcement learning algorithm which is widely used at present, double DQN, dueling DQN and learning from demonstration are integrated; states, actions, rewards and the experience pool based on the characteristics of series-parallel multi-speed hybrid powertrain are designed; the hybrid energy management strategy based on D4QN (Double Dueling Deep Q-Network with Demonstrations) algorithm is established. Based on the training results of D4QN algorithm, multi-parameter analysis under state and action space, HCU (Hybrid control unit) application and MIL (Model in-loop) test research are conducted. The results show that the D4QN algorithm can achieve both the approximate global optimal results, which differs from the result of dynamic programming by 0.05% under the training cycle, and establish the positive mapping relationship between state variables and action variables of the hybrid powertrain with excellent generalization ability, which can be applied to HCU and control the hybrid electric vehicle effectively in real time. Compared with the original rule-based energy management strategy for the hybrid electric vehicle, the fuel economy under WLTC cycle is improved by 9.64% after the application of D4QN energy management strategy. The proposed strategy can realize a termination of SOC (State of charge) within 50±10% under different initial SOC states for a battery of 1.8kWh, achieving the goal of SOC robustness. In addition, the proposed strategy has strong adaptability to the unknown cycles; the fuel economy of the vehicle after the application of D4QN energy management strategy in the untrained NEDC and CLTC-P cycles is improved by more than 10% compared to the WLTC cycle.

Authors: Jassim Anwar , Hussain Amera , Al-Shwaily Ali
Published: October 2023

The present study adopts AHP and GIS techniques to produce a landslide susceptibility index map of the Zurbatiya region. The research area is located in eastern Iraq, within Wasit Governorate. The local terrain predispositions were represented by the landslide conditioning parameters that were chosen: slope angles, geology, slope aspect, topographic elevation, distance from faults, and distance from valleys. The spatial resolution used for the raster-based study is 12.5×12.5 m. The AHP scale determines the relative importance of each element, with the slope angle having the largest weight (9) then geology and slope (7), aspect and elevation (5), and distance from faults and distance from valleys having the lowest relative importance (3). Depending on the landslide susceptibility index map, the low landslide susceptibility class has the highest percentage (41.2%) for the whole region, followed by the moderate landslide susceptibility class, which its share (39.9%), then the high landslide susceptibility class, with its share (14.8%), where, the very high share (3.9%). The landslide susceptibility index map was tested within the fieldwork stage in which 14 stations are selected within these four zones (low, moderate, high, and very high) where stations 1, 3, 4, 6 and 7 are distributed within the very high zone, station (8) within the high zone, stations 2, 9, 10 and 12 within the moderate zone and stations 11,13 and 14 within the low zone. Finally, it can be seen that they are an exact match when comparing the landslide susceptibility index map with the fieldwork stage, which is based on the previous failures and which are expected to occur.

Megawati Soekarnoputri is the 5th former president of Indonesia and currently serves as chairman of the PDIP party. As an influential politician in Indonesia, all his actions and words can influence public opinion. At the online webinar entitled "Prevent Stunting for Golden Generation", Megawati alluded to the condition of the people who are facing the problem of scarcity of cooking oil. He responded to this problem by assuming that the community's reaction was excessive regarding the problem of scarcity of cooking oil. As a result of her response, Megawati received various criticisms from the public through various media. This research will focus on Megawati's response with the aim of knowing linguistic elements, the process of text production and consumption, as well as the socio-cultural conditions of society. This qualitative research uses the critical discourse analysis model of Norman Fairclough which divides the analysis into three dimensions, namely text analysis, discourse practice analysis and sociocultural analysis. The research results show that there are several cohesions and coherences that shape discourse and diction which indicate the communicator's view of the audience, the process of text production and consumption goes according to the topic being discussed but there are statements that make some groups feel unacceptable and the way of delivery is not wearing it, and social and cultural background that influences the formation of discourse and the response it receives because the discourse has something to do with sociocultural situations.

Polypropylene is converted into bio-oil through catalytic pyrolysis using dolomite as a catalyst. The purpose of this study was to determine the effect of using dolomite directly without prior treatment on the bio-oil produced from the pyrolysis of propylene plastic. The amount of loading catalyst used is 5%. Increasing the pyrolysis temperature from 350 to 450 ℃ increased bio-oil from 35.56 wt% to 64.84 wt% by reducing gas to 21.08 wt%. In thermal pyrolysis, the production of bio-oil is 85 wt% with 19.30 wt% char. In the GC-MS analysis of bio-oil from thermal and catalystic pyrolysis, the most dominant alcohol composition was obtained. Based on the result of the analysis, it can be concluded that the bio-oil obtained can be further developed into fuel.

Geologically speaking, Labuang Rano Village, Mamuju City area is composed of rocks from the Adang Volcano Formation. Based on the results of the site survey, it was found that there is a spring with a slight discharge. The emergence of these springs is not yet known, so further analysis is needed. An approach used to determine subsurface conditions is the geophysical approach, especially the geoelectric method. This study aims to analyse the subsurface geological conditions using geoelectric to find the factors that influence the emergence of springs. Geoelectrical measurements, observations of rock outcrops, and the findings of previous research are used as data sources. The results of the analysis show that the subsurface geological conditions consist of 3 layers. The topmost layer is tuff rock, the 2nd layer is volcanic breccia and the 3rd layer is andesite rock. Based on the resistivity cross-section, it can be seen that there is a fracture that cuts vertically in the tufa rock layer from a depth of 13 m to the surface in a northeast-southwest direction. Thus, it can be concluded that the emergence of springs at the study site was caused by a fracture that cut the tufa rock layers vertically from a depth of 13 to the surface. The fracture which is the medium for groundwater to emerge onto the land surface forms a spring.

Law Enforcement Of The Stockholm Declaration Principles In Relation To Forest And Land Fires In Indonesia
Authors: Indien Winarwat
Published: October 2023

The frequent forest fires in Indonesia are of important concern for ASEAN countries since Indonesia is considered the biggest contributor to smoke-haze pollution. Land and forest fires in Indonesia contribute to exporting haze to Malaysia and Singapore, causing the two countries to urge Indonesia to immediately address the issue of forest fire since the resulting smoke haze is terribly disturbing and dangerous for the people of both countries. Indonesia is one of the developing countries currently in the international spotlight due to the severe damage to its tropical forests annually. Land and forest fires in Indonesia constitute a transnational environmental pollution, creating a thick smoke haze to disrupt the continuity of life and economic activities in most of the region of ASEAN countries. The impacts of the smoke haze caused by forest and land fires are immense, requiring the Indonesian Government to take a firm stand by immediately making regulations to ensnare forest and land burners to cause a deterrent effect not to do the foregoing again. The present paper addresses law enforcement arrangements for land and forest fires in Indonesia and the harmony of the Stockholm Declaration principles with law enforcement arrangements for forest and land burners. The present study is analytical descriptive using the normative juridical approach. It describes the phenomenon and analyzes the legal issues of law enforcement arrangements for land and forest fires. Results show that law enforcement by the Government of Indonesia is regulated by Law Number 41 of 1999 concerning Forestry, Law Number 18 of 2004 concerning Plantations and Law Number 32 of 2009 concerning Environmental Protection and Management. Each of these laws includes provisions on criminal sanctions and fines for forest and land burners. Law enforcement of the Stockholm Declaration principles for forest and land fires is accommodated in Articles 49 and 50 of Law on Forestry.
