Published: January 2024

Dengue Hemorrhagic Fever (DHF) is a disease that currently has significant morbidity and mortality rates. In Indonesia, the trend of DHF cases has increased and decreased every year. This study aims to analyze the development of dengue cases by considering two indicators, namely dengue incidence rate and dengue case fatality rate (CFR) during the period 2012-2022, to know the pattern of dengue disease in Indonesia, and evaluate the government's target in handling dengue cases based on IR and CFR rates. The data used is secondary data obtained from the 2021 Indonesian Health Profile and the 2022 Dengue Fever Annual Report. IR and CFR data were analyzed using Microsoft Excel which will be interpreted in the form of graphs to illustrate the trends and patterns of DHF cases in Indonesia, IR maps in 2021 and 2022 were analyzed using ArcGIS software. Based on the results of the analysis, the development of dengue cases during the period 2012-2022 experienced a misalignment between the increasing trend of IR and CFR. The IR value experienced significant fluctuations from 37.3 per 100,000 population in 2012 to 52.07 per 100,000 population in 2022, while the CFR value during the period 2012-2022 tended to decrease from 0.90% (2012) to 0.86% (2022). This pattern reflects the complex dynamics of DHF epidemiology, where an increase in cases is not always followed by an increase in fatalities. The IR and CFR achievements for 2022 have not met the government's expectations, with only 16% of districts/cities having IR values ≤ 10/100,000, while the CFR value reached 0.86%, slightly above the set target of 0.7%.

The method used in the research was a qualitative approach with a case study method. The selection of informants was carried out using a purposive sampling technique to select informants consisting of 9 key informants, namely volunteer friends exploring children in Jambi and also Waris from the Anak Dalam tribe, as well as five supporting informants, namely Tumanggung, parents from the Anak Dalam tribe and also the community. The data collection techniques used were observation, in-depth interviews and documentation studies. Data analysis was done through data reduction, presentation, and conclusion. This research also used data triangulation techniques to test the validity of the data. The findings of this research were that empowerment in education provides a way for tribal children to learn how to read, write and count. If we look at the empowerment process carried out by the Deep Child Exploration Friends (SEAD) Jambi for children from the inner child tribe, the teaching and learning process begins with an introduction stage for all children of different ages after new material improvements have been made. What will be taught is differentiated from children's material, which is still in the introductory stage. Apart from that, if we look at the planning carried out by Jambi Children's Exploration Friends (SEAD), it is always adjusted to the situation and conditions in the field. There is no element of coercion, but it is carried out with a first approach and adaptation to the children, such as by teaching them to play first, eat and sing together. In the teaching and learning process, the methods used are also adapted to the children so that they are not boring and always look for ways to keep them happy during the empowerment activities.

Along with the times, synthetic composite materials are often used as materials for making reinforcing car panels, car dashboards and other interior devices. Although synthetic composite materials have strong strength, synthetic composite materials are less environmentally friendly and have an expensive price. Natural fibres are an alternative to synthetic fibres in order to reduce natural pollution and reduce production costs. Therefore, in this research I will use palm fibre and resam as reinforcement material. The purpose of this research is to find out whether mixing between resam fibre and palm fibre to make a car dashboard has reached the standardised value of making a car dashboard. The hand lay-up method will be combined with the Taguchi method in the L9(34) orthogonal matrix design used as a guide for making test specimens. With tensile and impact testing.

Published: January 2024

Understanding the responses of seabirds to climate-induced variations in phenology and abundance of their prey is key to developing ecosystem-based fisheries management measures that benefit higher trophic levels. The match/mismatch hypothesis (MMH) emphasizes the need to consider synchrony in the seasonal cycles of predators and prey, while the match/mismatch/abundance hypothesis (MMAH) proposes that prey abundance may reinforce/compensate mismatch effects. This study considers the effects of both variations in seasonal availability and abundance of lesser sandeel Ammodytes marinus on hatching, fledging and breeding success of 5 seabird species: black-legged kittiwake Rissa tridactyla, Atlantic puffin Fratercula arctica, razorbill Alca torda, common guillemot Uria aalge and European shag Gulosus aristotelis. Consistent with MMH, temporal asynchrony between sandeel availability and seabird breeding schedules affected productivity in 4 species. The effects of trophic asynchrony were either reinforced or compensated by sandeel abundance for some species, supporting MMAH. Breeding success in the late-breeding kittiwake was high when conditions favoured both high sandeel abundance and temporal synchrony while the cost of asynchrony could be compensated by high sandeel abundance in the earlier-breeding puffin. Differential effects of sandeel abundance and trophic synchrony at different stages of the seabird breeding season suggest that distinct mechanisms are involved. The effects were most evident in the most sandeel-reliant seabirds. As further disruption of sandeel phenology and abundance is anticipated under the current climate crisis, the present study is an important step towards understanding bottom-up effects of environmental change on higher trophic levels.
Reflexive Wonderings: Prospects and Parameters of a Heideggerian Approach to Film as Philosophy
Authors: Rossouw Martin P.
Published: January 2024

This response article addresses the conception of “film as philosophy” developed by Shawn Loht in his book Phenomenology of Film: A Heideggerian Account of the Film Experience (2017), with specific attention to the relevance and implications of Loht's approach for the broader debate beyond a strictly Heideggerian film-philosophy. The article proceeds in three distinct takes. The first take examines Loht's later-Heideggerian inspirations, arguing that although these more fundamental notions of philosophy open significant possibilities for film as philosophy, they nevertheless run the risk of being too embracive, as well as too elusive, to make a distinctive contribution to the debate. For its second take, the article resets its initial point of departure by considering how the earlier Heidegger of Being and Time cues in Loht's approach a special – albeit, ultimately, untenable – investment in cinematic reflexivity, with the stylistic hallmarks of Terrence Malick serving as a test case. In its final take, the article concludes by venturing a possible solution to the questions raised in the first two takes. Here it is proposed that, in contrast to Loht's general interest in cinematographic devices, the voiceover holds a far more sustainable promise of reflexivity, while at the same time giving more prominence to the viewer's acts of listening – which is what a quintessentially Heideggerian film phenomenology surely asks for.
Response to Critical Views of Phenomenology of Film

This article responds to critical views of John Rhym, Martin Rossouw, Ludo de Roo, and Annie Sandrussi on my 2017 book Phenomenology of Film: A Heideggerian Account of the Film Experience. The article also takes up positive footholds from the analyses of Chiara Quaranta and Jason Wirth. The main topics addressed include Martin Heidegger’s ontic-ontological distinction; the notion of film-as-philosophy; being-in-the-world read as being-in-the-film-world; and questions surrounding the facticity and identity of the film viewer.
Subjective Interpretation in Flash Fiction
Authors: Besong Donald
Published: January 2024

This analysis paper presents two of the author’s flash fiction stories. He encourages readers to make sense of the narratives in their own way. The paper argues that revealing too much of the story would deprive the reader of the stimulation which was supposed to draw them toward closure. The author observes that the vast majority of recent flash stories do not have the above-mentioned ironic twist but hopes that this paper will proliferate the endangered mystique.The author terms the mistake of telling the reader too much as ‘the spoiler’. The term is often used in the movie industry to mean a piece of information that—too early on—reveals important plot details, twists, or surprises about a movie. It is intended that this paper remains short and easy to understand so that readers can grasp flash fiction and be interested in stories of that nature.

Mitra Pengabdian Masyarakat is a waste bank that manages various waste generated by households. One of the dominant types of waste is plastic waste of beverage and food packaging, which are types 1 and 5. This waste has high economic value if processed into displays, as raw material for recycled products. Around the village there are a number of sources of plastic waste. Thus, this waste bank has the potential to become a micro industry for displaying plastic waste, food and beverage packaging. The purpose of this PkM is to initiate waste banks into plastic production units for the plastic recycling industry.The method carried out is to improve the ability of waste tire managers to become production system managers. For this reason, training on production system management was given to waste bank managers. Then training on the operation and maintenance of plastic chopper machines is given. After that, assistance is carried out so that they can run the production system. As a result, they already understand the management of the plastic display production system for food and beverage packaging waste. In addition, it can also produce products according to consumer needs. This production unit can only run next year, because it requires an injection of capital to be obtained from the 2024 village budget allocation.

When talking about current business developments, there has been a lot of talk about where 2023 is the year towards a recession situation. This condition will certainly have an impact on all aspects of the main activities of the business sector, which inevitably must be prepared to face heavy burdens not only due to intense competition, but also sluggish conditions which can reduce business turnover. Of course, it's not strange if the end of all business is to get maximum income in which it must be considered as profit. Various efforts need to be made by all business scales, including MSMEs. Even though there is a long story that MSMEs always manage to get through even difficult situations, of course you can't if you just wait for what will happen in the future. One effort that can be done by adjusting all the resources owned by a place of business is to strengthen the business name and promote it more broadly through a business profile (company profile) that can be reached by the whole community as potential customers. A business profile that can highlight various characteristics of a place of business not only enhances a positive image in the eyes of consumers but also can reach some opportunities to bring in investors who can work together to develop the business.

The ODJG group (People in Mental Disorders) is a community group engaged in social activities: helping, guidance, and mental health rehabilitation for ODJG who have undergone psychiatric medical treatment from a Mental Hospital. To carry out its activities, this group formed a business that produces food and beverages (MaMin) made from Moringa leaves (moringa tea, instant Moringa, Moringa ice wax, Moringa yogurt, Moringa pudding, Moringa flower extract). where the products have been marketed in Malang and surrounding areas. However, the production process encountered several obstacles: the lack of production equipment, the lack of maintaining product quality and the health of the work environment, and the lack of marketing techniques. Community service (PkM) aims to increase partners' ability to produce quality, safe, dan healthy MaMin made from Moringa leaves. The methods used in solving partner problems: 1). Production equipment grants, 2). Excellent and safe production technique training (GMP and HACCP),

3). Marketing digital training (digital marketing), 4). Production and marketing assistance and consulting. The results of the PkM activity show that there is an increase in the knowledge and skills of partners in producing healthy and quality MaMin and marketing it with digital marketing media

Introduction

Diabetes is a major cause of disease burden with considerable public health significance. While the pancreas plays a significant role in glucose homeostasis, the association between pancreatitis and new onset diabetes is not well understood. The purpose of this study was to examine that association using large real-world data.

Materials and methods

Utilizing the IBM® MarketScan® commercial claims database from 2016 to 2019, pancreatitis and diabetes regardless of diagnostic category, were identified using International Classification of Diseases, Tenth Revision [ICD-10] codes. We then performed descriptive analyses characterizing non-pancreatitis (NP), acute pancreatitis (AP), and chronic pancreatitis (CP) cohort subjects. Stratified Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) of diabetes across the three clinical categories.

Results

In total, 310,962 individuals were included in the analysis. During 503,274 person‐years of follow‐up, we identified 15,951 incident diabetes cases. While men and women had higher incidence rates of CP and AP-related diabetes, the rates were significantly greater in men and highest among individuals with CP (91.6 per 1000 persons-years (PY)) followed by AP (75.9 per 1000-PY) as compared to those with NP (27.8 per 1000-PY). After adjustment for diabetes risk factors, relative to the NP group, the HR for future diabetes was 2.59 (95% CI: 2.45-2.74) (P<0.001) for the CP group, and 2.39 (95% CI: 2.30-2.48) (P<0.001) for the AP group.

Conclusion

Pancreatitis was associated with a high risk of diabetes independent of demographic, lifestyle, and comorbid conditions.

Published: January 2024

This review presents the advancements in nanomaterial (NM)-induced pyroptosis in specific types of cells. We elucidate the relevance of pyroptosis and delineate its mechanisms and classifications. We also retrospectively analyze pyroptosis induced by various NMs in a broad spectrum of non-tumorous cellular environments to highlight the multifunctionality of NMs in modulating cell death pathways. We identify key knowledge gaps in current research and propose potential areas for future exploration. This review emphasizes the need to focus on less-studied areas, including the pathways and mechanisms of NM-triggered pyroptosis in non-tumor-specific cell types, the interplay between biological and environmental factors, and the interactions between NMs and cells. This review aims to encourage further investigations into the complex interplay between NMs and pyroptosis, thereby providing a basis for developing safer and more effective nanomedical therapeutic applications.
