Published: January 2024

Medical histories of patients can predict a patient’s immediate future. While most studies propose to predict survival from vital signs and hospital tests within one episode of care, we carried out selective feature engineering from longitudinal medical records in this study to develop a dataset with derived features. We thereafter trained multiple machine learning models for the binary prediction of whether an episode of care will culminate in death among patients suspected of bloodstream infections. The machine learning classifier performance is evaluated and compared and the feature importance impacting the model output is explored. The extreme gradient boosting model achieved the best performance for predicting death in the next hospital episode with an accuracy of 92%. Age at the time of the first visit, length of history, and information related to recent episodes were the most critical features.

Published: January 2024

Interferons (IFN) constitute a primary line of protection against mucosal infection, with IFN research spanning over 60 years and encompassing a vast ever-expanding amount of literature. Most of what is currently understood has been derived from extensive research defining the roles of “classical” type I IFNs, IFNα and IFNβ. However, little is known regarding responses elicited by less well-characterized IFN subtypes such as IFNε. In this paper, we combined a deductive text mining analysis of IFNε literature characterizing literature-derived knowledge with a comparative analysis of other type I and type III IFNs. Utilizing these approaches, three clusters of terms were extracted from the literature covering different aspects of IFNε research and a set of 47 genes uniquely cited in the context of IFNε. The use of these “in silico” approaches support the expansion of current understanding and the creation of new knowledge surrounding IFNε.

Incorporating clinical and environmental data holds promise for monitoring vulnerable populations at the community level. This spatial epidemiology study explores the link between traffic-related air pollution and breast cancer mortality in Seoul, using public socioeconomic and clinical data from Samsung Medical Center’s registry (N=6,089). Traffic and socioeconomic status were collected from official sources and integrated for spatial analysis. The findings revealed a significant association between adult breast cancer mortality and districts with high road density, NO2 emissions, and family income (p<0.05). Significant spatial autocorrelation of residuals was observed (Moran’s I test p<0.001).
TLR4 GENE POLYMORPHISM rs2149356 IN TYPE 2 DIABETES - POSSIBLE RELATIONSHIP WITH DIABETIC MACULAR EDEMA
Authors: Ivanyuta E. P.
Published: January 2024

Background. Polymorphisms in the non-coding regions of the TLR4 gene are known to be associated with the risk of ocular complications of type 2 diabetes (T2DM), with some polymorphisms having no association, others increasing the risk, and some reducing the risk of complications.

Aim: to establish the association of the TLR4 gene polymorphism rs2149356 with diabetic retinopathy (DR) and diabetic macular edema (DME) in T2DM.

Materials and methods. The study included 81 patients (81 eyes) with T2DM, in whom, according to the guidelines of the American Academy of Ophthalmology (2002), DR and DME were detected, the control group consisted of 50 patients (50 eyes) with T2DM, normalized carbohydrate metabolism, DR 0 (no retinopathy) and absent DME. Genotypes of rs2149356 were determined by real-time polymerase chain reaction using the Gene Amp® PCR System 7500 amplifier (Applied Biosystems, USA) and TaqMan Mutation Detection Assays Life-Technology (USA). MedStat and MedCalc v.15.1 software packages (MedCalc Software bvba) were used for statistical research.

Results. In this study, no association of the genetic polymorphism rs2149356 of the TLR4 gene with the development of DR and DME in T2DM was found (p=0.326). Stratification by stages of DR showed no dependence of the distribution of genotypes, while according to the degree of DME, the distribution of genotypes was definitely different in DME 3. Thus, among the carriers of the ancestral genotype G/G, none of DME 3 was found, the borderline level of the total retinal volume (TRV) was 6.7 mm3, above which DME 1 or DME 2 was determined. All carriers of the heterozygote G/T had DME 3, and for carriers of the minor homozygote T/T, two threshold values of TRV were determined: above 6.7 mm3, DME 1 or DME 2 was determined, and higher than 8.7 mm3 – DME 3. Analysis of the relationship between the rs2149356 TLR4 and the phenotype of patients showed greater central retinal thickness and TRV in heterozygous and minor homozygous T/T carriers, which corresponded to greater retinal damage compared to ancestral homozygous G/G carriers (p<0.001).

Conclusion. Data were obtained on the association of diabetic retinal damage with the rs2149356 TLR4 – retinal edema was more pronounced in carriers of the T allele.

Investigation of the families Asteiidae, Lauxaniidae, Mydidae, and Neriidae (Insecta: Diptera)
Authors: Marchiori Carlos Henrique
Published: January 2024

Adults of the Asteiidae family can be captured with Malaise traps set within the forest, but the best way to obtain specimens is when they are found congregating. At these sites, one can easily capture the adults with a vacuum cleaner. The larvae may be scavengers on the excrement of other insects. Adult Lauxiniidae are sedentary and like shaded places. They can be found in a wide variety of environments such as grasses, flowers, compost capitula, and low foliage, mainly in humid forests near streams and swamps. It was observed that they are more active at the end of the afternoon and, therefore, are easier to collect during this period. Many adults are scraper fungi found on leaves. Larvae in this family are primarily saprophagous, commonly found in fallen leaves, rotting wood or straw, decaying vegetation, and bird nests. Mydidae is a relatively small group of Asiloidea (Diptera) that comprises the largest flies in the world, and little is known about the nature of adults; males visit flowers occasionally, and females are unlikely to feed. The Mydidae constitute a family of orthorrhaph flies, which includes the largest known dipterans. Larvae of several species of Mydidae feed on immatures of Coleoptera and can be found in nests of _Atta _spp., and _Acromyrmex _spp. ants. All other Neriidae probably feed on other decaying plant organic tissues, such as plant resins and fruit secretions, and more rarely on animal manure and organic matter. Some species of _Glyphidops _Enderlein, Sepúlveda et al. (2014) and _Nerius_ Fabricius, 1805 were observed on freshly felled trunks and branches, in galleries of wood saw beetles (Coleoptera, Cerambycidae), while others may be associated with human crops, such as squash, cotton, banana, gourd, and papaya. Some species have high rates of synanthropy, being attracted by cooking odors and becoming common inside homes. Some species are used for behavioral and sexual selection studies. The mini-review aims to verify the themes of the Asteiidae, Lauxiniidae, Mydidae, and Neriidae families such as morphology, biology, and systematics. In terms of the type of research source, we worked with scientific articles published in national and international journals. This modality of production, in addition to being commonly the most valued in the set of bibliographic production, is the most easily accessed. Access to articles was through virtual libraries such as SciELO, ResearchGate, and Hall. Considering only this section constitutes a limitation of the study since articles belonging to journals that integrate other sections of the aforementioned electronic library could also contribute to the discussion of knowledge production and the writing of interpretative syntheses of each theme.

Recent advances in sensor technology have increased the ability of humans to measure a wide range of phenomena and events. Nevertheless, in some cases, due to a variety of limitations, only a few sensors can be deployed at a given site. Consequently, setting up enough sensors at the right places to provide uniform monitoring can be difficult. In addition, virtual sensing, which is a set of strategies for replacing a portion of physical sensors with virtual sensors, has recently been developed. Therefore, this work leverages the imputation capability of PGAIN-VS to develop a black-box data-driven virtual sensing approach named sensor rotational measurement for the purpose of reducing the number of physical devices to be used in reality while still ensuring monitoring accuracy. The approach takes advantage of the PGAIN-VS and Borda voting methods to determine the subset of real sensors that can take turns observing information within an interval of time. The approach is seen as a black-box objective optimization problem with constraints that is solved by the OpenBox tool. We evaluated our method on several real-world datasets and achieved promising results, with the overall number of physical sensors reduced by up to 20%.

Image retrieval is a prominent subject of study in the fields of image processing and computer vision. With its application in various domains, such as logo search, product search or general image search in Google, Bing, etc., image retrieval has received significant attention for many years. In this work, we study and investigate a framework that leverages visual transferring fea-tures and hashing algorithms for the purpose of finding similar images in a dataset. The key idea of our solution is to find the answer to the following question: “How can we convert an image into binary code and search it more efficiently in a large-scale dataset?”. To achieve this pur-pose, we use pretrained CNN models from ImageNet for image representation and then convert them into binary code by using hashing algorithms. These images in the dataset are represented by binary codes, and the Hamming distance is used to find the images in the dataset that are in-dexed. To demonstrate the robustness of the system, we systematically tested the performance of the system based on speed with raw indexing and hashing indexing on 4 datasets: CIFAR-10, Caltech-101, Oxford-102-Flowers, and MS-COCO 2017. The experimental results show that lo-cal sensitive hashing (LSH) algorithms with 2,048 bits in binary code demonstrate the same or greater precision than raw indexing. Furthermore, the findings show that the MobileNet architec-ture consistently outperforms other architectures across these datasets, effectively balancing speed and precision.
Factors affecting local people's participation in tourism activities
Authors:   Banking Academy of Vietnam, Thi Dang Thuy Duyen
Published: January 2024

Tourism development is the choice of many countries, provinces, and cities. Tourism has both taken advantage of local and available natural resources and built through investment. At many tourist sites, when developing tourism, the government has to recover and mobilize land from local people. Most of the land taken is agricultural land, so their occupations and livelihoods change significantly after tourism is invested. So when the industry changes and local tourism is invested, are local people willing to participate in tourism activities? The author conducted a survey of more than 140 households in the southern Red River tourism sub-region as a basis for research. The purpose of the study is to examine the factors affecting the participation of local people in tourism activities, such as tourism development policies, infrastructure, tourism potential, and long-term income. The research results show that all factors have a positive impact, with two factors, long-term income and tourism development potential, having the most positive impact on people's participation in tourism activities. Tourism infrastructure and tourism policy factors have the third and fourth largest impacts on people's willingness to participate in tourism. From there, local authorities and tourism businesses can consult to come up with appropriate solutions to attract workers to work at tourist destinations. Besides attracting local workers, it can also attract residents from neighboring areas to participate in tourism activities. In addition, the impact of tourism potential factors means that preserving and promoting sustainable tourism potential is also an issue that the government and people must pay attention to when developing tourism in the future.
Study the effects on the phonon drag Seebeck coefficient of bilayer graphene and bilayer graphene−bilayer graphene double layers

Published: January 2024

This paper presented the investigation of the influence of the temperature−dependent screening effect on the Seebeck phonon drag coefficient Sg of a monolayer of bilayer graphene (BLG) and a BLG−BLG double layer placed in an air environment. For a system in an air environment, the two-dimensional electrons of the BLG was assumed to interact only with the intralayer deformation acoustic potential phonons in the BLG. After reviewing the results published by Kubakaddi and Bhargavi, “Enhancement of phonon-drag thermopower in bilayer graphene” in Phys. Rev. B 82, 155410 (2010), this paper expanded the mentioned-results to encompass the screening and double layers and found that the phonon drag coefficient in the BLG monolayer system was strongly reduced by the screening effect, even up to several orders of magnitude compared to the zero temperature screening function, as shown in some recent publications. When comparing the effect of electron screening in the second layer on electron-phonon interaction in the remaining layer, or on the intralayer screening function, the distance between the two layers was small. The screening effect of the second layer significantly reduced the magnitude of the phonon drag Seebeck coefficient Sg in the BLG-BLG double layer. The effect of temperature, layer spacing and particle density on Sg for symmetric and asymmetric systems with varying layer densities were also investigated.

Published: January 2024

Cloud data owners prefer to outsource data because of ease in maintenance. Data confidentiality of this outsourced sensitive data is a major task. The searchable encryption technique helps to carry out searches on encrypted data without decrypting it. In the data outsourcing environment, volume of data is increasing rapidly. Hence the time required to build the index and to carry out searches is also increasing exponentially. This makes it more difficult to build a system which is efficient, reliable and can cope up with growing data. In this paper, a parallelization technique to build the index on outsourced data is proposed. This technique minimizes the time required to construct the index. It also supports secure ranked retrieval using bucketization technique. The buckets are formed using Hadoop map reduce framework which achieves significant efficiency. The proposed method prune the keyword dataset, which helps in significant reduction in the size of index. Through extensive experiments using standard dataset, the performance of the system is validated. The experimental results show that the proposed system requires less time for index construction and hence improves retrieval efficiency.

Published: January 2024

Twitter has become a popular platform for sharing health information, including diabetes-related content. Recent research studies have shown that Twitter data can be used for various purposes such as monitoring illnesses, promoting health, analyzing sentiment, and potentially aiding in medical directing. However, detecting fitness-related tweets in the vast amount of data on Twitter can be difficult. This pilot study, therefore, aimed to classify patient text about drugs and disease-associated tweets into meaningful health-related segments. The unlabeled dataset is divided into several groups using an unsupervised learning technique called K-Means Clustering, using this first label the text and followed by a combination of neural networks and machine learning classifiers, they classified 32046 diabetes-related tweets and 161290 drug text lines into five groups. Approximately 66.38% of drug line text was classified as health-related, with 55.14% “treatment and medication”, 7.10% “prevention” and 4.14% “symptoms and causes”. Over 33% were categorized as “Other and News”. If we talk about the tweets as a dataset then the tweet was classified as health-related, with 44.30% “treatment and medication”, 7% “prevention” and 5.3% “symptoms and causes”. Over 56.10% were categorized as “Other and News. After this multiclass classification, we applied three machine learning and two deep learning models to find accuracy, precision, recall, and F1 scores. Drug review was used as a dataset then SVM and LR models provided an accuracy of 98% and when tweets were used as a dataset then LR models provided an accuracy of 97%. This research shows the importance of social media data in the decision-making system in the healthcare domain.

Published: January 2024

La figura femenina en el arte cinematográfico ha sido mostrada a través de arquetipos y cumpliendo distintas funciones. Nos proponemos en este estudio analizar los personajes femeninos a través de la narrativa audiovisual en dos películas emblemáticas de la cinematografía de Hitchcock: Recuerda y Vértigo, en las que la mujer se contempla como empoderada, pero también sometida llegando a una negación de su propia identidad. Consideramos que la forma del tratamiento de la mujer en el cine de dicha época radica en la situación social de la misma, sufriendo un tratamiento discriminatorio, que es admitido por los personajes femeninos justificandolo en un enamoramiento, que anula la propia personalidad.

Published: January 2024

Different types of materials were used in aim to reduce pain and to alleviate of symptoms. These materials have been used for decades like formocresol, cresatin, eugenol, CMCP and iodine-potassium because of their antiseptics and germicidal effects that should reduce the pain. In recent years the introduction of pulpotec material that contain both formalaldehyde and dexamethasone acetate may provide both antiseptics and sedative effect of steroids.

The aim of this study is to evaluate the use of pulpotec and compare it with other most common materials used in pulpotomy as emergency treatment dressings (camphorated monochlorphenol and eugenol).

 Materials and methods: sixty patients (26 meals and 45 females) were included in this study after their approval to the treatment protocol. The three materials were applied. All the participants of the three groups recalled after eight hours, twenty-four hours and seventy-two hours. Results and conclusion: the pulpotec group shows complete relief of pain 100% will the other two groups show mild to severe pain after one to three days. On conclusion, steroids can be used locally to provide alleviation of pain in symptomatic teeth due to their anti-inflammatory effect and reduce their side effect. That will diminish the use of systemic antibiotics.

Authors: Ali Hadi Noor , Qadir Omer Zana
Published: January 2024

Aim of the study: The purpose of this research was to investigate how the static and kinetic friction between the orthodontic bracket and archwire will be affected by artificial saliva (AS), oil-containing mouthwash (TTO), and olive oil (OO).

Materials and methods: On an Instron universal testing machine with a load cell of 10N and a speed of 2 mm/min. Thirty premolar brackets with 0.019 x 0.025inch stainless steel archwires were assessed. The samples were allocated into three groups randomly. Ten test units were immersed in artificial saliva AS (control group), Tea tree oil mouthwash TTO, and olive oil OO (study groups) for 90 minutes at room temperature. Each test unit is evaluated once only. Statistical analysis used was the ANOVA and Post Hoc LSD tests for parametric tests, the Kruskal-Wallis test, and the Pairwise Comparison test for non-parametric tests.

Results: The samples immersed in olive oil significantly showed increased static and kinetic frictional resistance (p= 0.009 and 0.001, respectively), and the TTO showed the least static and kinetic frictional resistance.

Conclusion: The 90-minute immersion in oil-containing mouthwash reduced static and kinetic frictional resistance between the orthodontic brackets and archwires, while olive oil (OO) significantly increased them. Based on these findings, oil-containing mouthwash can be prescribed as an excellent prophylactic agent for orthodontic patients. However, the OO is not recommended during the sliding mechanics.
Supportive Periodontal Treatment for the natural dentition and dental implants: a review
Authors: Taher Ali Ali , Jabbar Ali Banaz
Published: January 2024

Aim: To assess the importance of successful periodontal treatment during long-term supportive periodontal treatment.

The maintenance phase has been named the "cornerstone" of effective periodontal treatment when a patient is transferred from active treatment to a maintenance phase which is considered the final stage in comprehensive patient care, it takes effort and time from the patient, staff, and the dentist.

Surgical and non-surgical techniques are used in periodontal therapy; patients should be put on a schedule of periodic reminder visits for supportive care once periodontal therapy is completed to avoid the recurrence of the disease. PD can recur due to poor mouth oral hygiene, insufficient subgingival removal, the microscopic nature of the dentogingival unit healing after periodontal treatment, and other factors. As a result, effective treatment should be provided to prevent disease recurrence.

Conclusion: The success of periodontal therapy is based on a continuous schedule of periodontal maintenance therapy

Published: January 2024

Background/ Aims: High bond strength of root perforation repair materials is essential for success of endodontic therapy. The aims of current study were to assist the push-out bond strength of 4 types of root perforation repair materials (Biodentine , Mineral trioxide aggregate, glass ionomer cement, and calcium hydroxide paste) from dentin, and to determine the modes of failure at debonded surfaces.

Materials and Methods: Forty lower premolars with a straight single root canal and matured apex were utilized. Then the teeth decorated  15 mm from the apex, and the middle third of the roots were cut perpendicular to their long axis in order to obtain sections with 1 mm thick.  After that instrumentation for the canal of the dentin discs with Gates Glidden was done from sizes 2-5 to result into standardized cavities with 1.3 mm diameter. After that, specimens were divided randomly into 4groups with 10 specimens in every group as follows: group I: Bio (Biodentine), group II: Mineral trioxide aggregate ( MTA), group III: GI (glass ionomer), and group IV: calcium hydroxide paste (Ca(OH)2).  Prepared cavity was then filled with each of the material tested according to the corresponding groups. after setting of the tested materials the specimens stored for one week and then push-out bond strength test preformed.

 Results: push-out bond strength of Biodentine was significantly higher than other tested materials.  Followed by Mineral trioxide aggregate, which exhibited significantly higher bond strength than glass ionomer and MTA materials,  while the Ca(OH)2 showed the lowest value of push-out bond strength.

Conclusions: push-out bond strength Biodentine, was significantly greater than MTA, GI, and Ca(OH)2. Therefore, BIO can be used successfully for treatment of root perforation that might occur during endodontic therapy of the root canal.

Aim:  To evaluate the knowledge and behavior of a group of dentists in Baghdad towards prescribing antibiotics to pediatric patients.

Method: A Cross sectional study was conducted by an electronic self- administered questionnaire to dentists specialized in Preventive or Pediatric Dentistry, general dentists with certificate in Preventive and Pediatric and Preventive Dentistry and to general dentists working in health centers of Al-Resafa in Baghdad. Open-ended and closed-ended questions were directed to the dentists regarding the knowledge and behavior towards prescribing antibiotics to children.

Results: (116) dentists responded to the questionnaire consisted of (36) specialized dentists in Pediatric or Preventive dentistry, (8) general dentists (certificate in Preventive and pediatric Dentistry) and to (72) general dentist. Most of the dentists with an age range from 21 to 30. Females constituted most of the sample (74.1%). General dentists represented the higher proportion (62.1%). Only (38.8%) of the dentists were self-educated whereas the medical websites seemed to be the main source (80.0%). Besides, only (13.8%) of total dentists have attended scientific medical course on antibiotics indications and/or resistance for the last two years. Amoxicillin was the main antibiotic prescribed for non-allergic children (75.9%), whereas Erythromycin and Azithromycin were prescribed for allergic children (73.3%). (42.2 %) of the sample prescribed antibiotics once per-week, while (13.8%) prescribed on need.

 

 Cellulitis contributed (60.3%) among conditions need prescription of antibiotics before and/or after the treatment. Regarding the prophylactic antibiotics, high risk cardiac conditions represented (93.1%).

Conclusion: Most of the general and specialist dentists were aware towards antibiotics prescription for children but lacked in updating their information which based primarily on their previous dental education.

The demand for fresh pineapple fruit is currently highest for the MD2 pineapple variety. Continuous efforts are made to enhance the quality of MD2 pineapples, including the fruit skin colour, flesh colour, sweetness, and minimizing sunburn damage. Bagging is one of the pre-harvest methods that can be employed for this purpose. This research aims to find suitable bagging materials that meet the industry's criteria and assess the severity of sunburn in each bagging treatment. A completely randomized design was used in this study, with six different bagging materials and pineapples aged 80 Days After Forcing (DAF). The bagging materials used were the control, blue Polyethylene (PE) bag, white PE bag, black patent bag, paper bag, and the existing cap-shaped bagging technique using recycled paper from banana bagging, as utilized by PT. Great Giant Pineapple. Each treatment involved 120 pineapple samples harvested at 140 DAF. MD2 pineapples without bagging were found to provide the best results according to PT. Great Giant Pineapple's criteria, with green skin colour (1.35%) and uniform yellow flesh (85.62%).

Wastewater treatment facilities at high places can give chances for renewable and sustainable energy generation by putting hydroelectric turbines at the input and drain channels of wastewater treatment plants, and they can also use the sludge generated during the treatment process to make biogas, which can be used to generate power. Purified water is subsequently used to irrigate decorative plants along highways, in gardens, and in woods. The fermentation wastes are utilized as organic fertilizer to improve agricultural soil quality. At the Gharyan sewage station, a hybrid system consisting of a hydroelectric station and an electric generator powered by biogas is proposed in this research. This is because the city is distinguished by its high location, which is approximately 713 m above sea level. The results showed that the proposed system would provide an electric power of 490 kW, which is sufficient to cover 87.5% of the electrical energy consumption of the station. The amount of treated water is approximately 13,000 m3/day, and the amount of organic fertilizer is about 17 tons/day. The investment value is anticipated to be around $1,478,000, while the cost of producing a unit of electric energy is expected to be 2.83 ¢/kWh. This system's yearly net profit is predicted to be $307,765. The capital's recovery period is anticipated to be 3.44 years. The planned hybrid system will limit the discharge of an estimated 1,886 tons of CO2 gas each year.
Hybridization potential of brown trout, with particular reference to invaded environments
Authors: Purchase Craig , Hanley Connor , Lantiegne Tyler , Poulos Steven

Hybridization is a complex process beginning with the mating of two species. However, hybrid offspring frequency does not predict hetero-specific mating frequency, as post-mating, both pre-zygotic and post-zygotic barriers influence their occurrence. Post-zygotic outbreeding depression usually results in poor embryo-juvenile survival or the production of sterile hybrid offspring. Females have more to lose with each hybrid fertilization than males, and thus should avoid it. Even if females choose con-specific males as preferred mates, they often cannot control which males release sperm during spawning. Polyandry is ubiquitous and may result in hetero-specific sperm competition. In such cases, cryptic female choice (the ability to bias paternity towards certain males under sperm competition) is the last line of defence to prevent hybridization of her eggs, and is highly adaptive if it enables con-specific sperm preference. Such seems to be the case with hybridization of Atlantic salmon (Salmo salar) and brown trout (S. trutta) in their native Europe. Under hetero-specific sperm competition, hybrid fertilizations in these fish are reported to be reduced via ovarian fluid mediated cryptic female choice. It is not known however whether the strength of this mechanism is dependent on reinforcement, and thus historical sympatry/allopatry of hybridizing populations. Brown trout are one of the world’s worst invasive species. Ecological impacts arise through competition with other species (e.g., Galaxids in the southern hemisphere, Oncorhynchus in western North America). Eastern North America is unique in containing native salmonids that evolved in the absence of brown trout, but have gametes that are compatible. The 140 year-old brown trout invasion of Newfoundland is ground zero to study these potential interactions. Their relatively low spread rate across the island may be the result of inherent poor productivity, but data suggest it could also be a function of hybridization with native Atlantic salmon and brook char (Salvelinus fontinalis).
LEGAL PROTECTION OF CONSUMERS IN HOME ORDER LETTER (SPR) FROM THE DEVELOPER
Authors: Francisca Maria
Published: January 2024

The initial process of buying a house at a developer company is carried out with a House Order Letter (SPR) and the consumer is immediately given a receipt for the purchase of a house unit. In its implementation, this SPR uses standard clause agreements which are more detrimental to consumers. In the course of this credit agreement, preceded by an SPR from the developer company, it became a thing that was detrimental to the community who had paid the receipt and was canceled unilaterally by the developer company on the grounds that the bank refused to apply for a mortgage. In this case, legal protection is needed for consumers to get a full refund of what they deposited because the unilateral cancellation has been carried out by the Developer Company. Business actors as parties who make agreements use standard clauses that tend to release, transfer or reduce their responsibilities which should be the responsibility of business actors, by violating Article 18 paragraph (4) UUPK, so that in general, consumer rights are still not protected because business actors are concerned with the fulfillment of protection for their parties against the risks they may face. The SPR agreement does not conflict with applicable law but its moral responsibility is required to protect consumers.
