Solar energy is one of the renewable energy sources and widely used to obtain thermal energy. The heat obtained from solar energy can be stored by using different systems. One of these systems is solar ponds. Solar ponds consist of layers whose salt density increases towards the bottom. In this study, the use of phase change materials to increase the heat storage performance of a model solar pond was investigated. The phase change material, Cetyl-palmitic acid eutectic mixture was prepared and its chemical properties were obtained by FT-IR spectroscopy. The thermophysical properties and surface morphologies were determined by using Differential Scanning Calorimetry and SEM. The obtained phase change material was applied to the inner surface of the heat storage zone. The temperature distribution of the solar pond was calculated numerically for with and without phase change material. As a result, it has been seen that the use of phase change materials with suitable thermophysical properties in solar ponds will contribute to long-term heat storage performance.

Introduction: In the context of skin aesthetics, the spotlight is focused on non-invasive cosmetic procedures. Studies have shown that micro-focused transcutaneous ultrasound (MFU). A commercially available device combines MFU with high-resolution ultrasound imaging. Some clinical studies have shown clinical synergy of MFU-high resolution with poly-L-lactic acid and a fractional or diluted CO2 laser with calcium hydroxyapatite. Objective: A systematic review was carried out on the main clinical findings of the use of micro-focused ultrasound and collagen biostimulation, with or without combination with calcium hydroxyapatite and poly-L-lactic acid, in the aesthetics of human skin, to highlight the safety, efficacy, and risk of bias. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from May to June 2022 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. Scientific articles from the last 20 years were selected. The quality of the studies was based on the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results: A total of 112 articles were found, and 12 articles were included in the systematic review. It has been shown that MFU-high resolution enables non-invasive tightening and lifting of sagging skin, and when combined dilute calcium hydroxyapatite, polycaprolactone, and/or poly-L-lactic acid is effective in improving sagging skin. Conclusion: It was concluded that MFU-high resolution targets the facial superficial musculoaponeurotic system, achieving non-invasive tightening and lifting of sagging skin, and when combined with dilute calcium hydroxyapatite, polycaprolactone, and/or poly-acid L-lactic is effective in improving sagging skin and cellulite.

Published: August 2022

Introduction: Orthognathic surgery (OS) is used to improve the patient's facial appearance and to correct maxillary and mandibular deformities resulting from malocclusions, disease, or trauma. In this context, genioplasty is a procedure to correct an aesthetic and functional deformity of the chin region, improving the contour. Moreover, anterior open bite (AOB) is the lack of vertical contact or negative overbite between the anterior teeth of the superior and inferior arches when the posterior teeth are in occlusion. Objective: The present study aimed to perform a brief systematic review with risk of bias analysis by funnel plot to highlight the main clinical approaches of orthognathic surgery in class II patients with open bites and also concerning genioplasty. Methods: The research was carried out from February 2022 to May 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 115 articles were found. In total, 57 articles were fully evaluated and 34 were included and evaluated in this study. And of the total of 34 articles, only 11 articles were developed as the main clinical results. A total of 32 articles were excluded because they did not meet the GRADE classification, and 16 were excluded because they were at risk of bias. The symmetric funnel plot does not suggest a risk of bias between the small sample size studies. A retrospective observational study compared 57 patient charts on treatment outcomes for anterior occlusion and vertical skeletal stability after maxillary or mandibular surgery to correct Class II malocclusion with a mild to moderate open bite. After surgery, 87% of Le Fort I patients and 63% of patients with bilateral sagittal split osteotomy had a positive overbite, and at the 6-month follow-up, the percentages were 90% and 74%, respectively. Another study showed Class II patients had significantly greater amounts of lateral and lower translation than class III patients. Also, genioplasty represents one of the most common auxiliary procedures and may be associated with corrective surgery for dentofacial dysmorphisms. However, care must be taken with mental nerve injuries, asymmetries, and intraoperative bleeding are the main immediate complications.

Introduction: In the scenario of eye diseases, diabetic retinopathy and retinal vein occlusion are the two most common ischemic retinopathies in the world. Ischemia is caused by retinal vascular diseases due to decreased blood perfusion and the appearance of areas of retinal non-perfusion. Also, age-related macular degeneration (AMD) is the most common cause of irreversible vision loss in people over 65 years of age in industrialized countries. By 2020, around 200 million people will be affected by AMD worldwide. Objective: the present systematic review study aimed to highlight the main clinical findings of the treatment of ischemic retinopathy and age-related macular degeneration through cell therapy with bone marrow stem cells. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The search was carried out from March 2022 to June 2022 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument. The risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: It was found 235 articles involving retinitis pigmentosa, macular degeneration, and bone marrow stem cell therapy. A total of 51 were fully evaluated and 28 studies were included and developed in a systematic review in the results field. The symmetrical Funnel Plot does not suggest a risk of bias between the small sample size studies. It was concluded that intravitreal injection of bone marrow-derived stem cells in a patient with retinal vascular occlusion sequelae demonstrated that the procedure is feasible and safe to be performed in humans as there were no signs of infection, inflammation, or development of intraocular tumor formation. Also, neurotrophic effects correlate with vasculature preservation, suggesting that bone marrow-derived stem cells can be used in the treatment of diseases such as retinal degenerations and vasculopathy that currently lack effective treatment. The authors concluded that stem cells can protect retinal cells from degeneration and also suggested that they were able to replace some types of lost retinal neurons.

Published: August 2022

Introduction: The use of dental implants in the rehabilitation of partially or edentulous patients followed an implant submersion protocol for 3-6 months during osseointegration. Currently, the immediate loading implant (ILI) is considered to offer many advantages for the patient and the clinician, including maintaining the height of the soft tissues and increasing the peri-implant bone density. Also, ILI is associated with reductions in patient pain, time, and material, with success rates of 95 to 100% being reported. Objective: To demonstrate the clinical success indexes of the immediate loading technique, to present the criteria of indication and the follow-up of the procedures. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out in February to May 2022 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: The analysis of the bibliography obtained showed that the success rates with the ILI technique are compatible with those of the late load, as long as certain guidelines are followed that were divided into factors related to the patient, the surgical technique, and the implant, the prosthesis and to aesthetics. The high success rate is a consequence of the correct surgical and prosthetic planning, and harmony between the implant system, patient, and dental surgeon. As for the region, currently, it can be said that ILI in total jaw rehabilitation is a procedure with high success rates that should and can be applied in all cases where the technique is efficient to provide adequate primary stability to the implants. Therefore, the technical improvement of the dentist becomes the main condition for this philosophy to be applied.

Published: August 2022

Introduction: Bone augmentation techniques have been increasingly indicated to recreate adequate bone height and volume for dental implant sites. Maxillary sinus augmentation can be performed with or without graft biomaterials. In this sense, fibrin-rich plasma (PRF) stands out, which is a three-dimensional (3-D) autogenous biomaterial. Objective: It was carried out a systematic review of the literature on the main considerations and clinical findings of bone grafting and fibrin-rich plasma in oral and maxillofacial surgery. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: The total of 256 articles were found. A total of 64 articles were fully evaluated and 28 were included in this study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 134 studies that were excluded with a high risk of bias (studies with small sample size). Also, 38 studies were excluded because they did not meet the GRADE. The application of autologous platelet-rich plasma provides benefits in promoting soft tissue healing and bone regeneration in different surgical procedures, as well as being favorable for bone formation processes for dental implants, especially when combined with xenografts. In addition, it is an autologous, low-cost biomaterial that does not require the administration of additives. However, further studies with larger sample sizes and longer follow-up times are needed to provide more substantial evidence of the efficacy of platelet-rich plasma in promoting soft and hard tissue healing.
Altered Vaginal pH Value and Enterobacteria as a Risk Factor in the Development of Precancerous Lesions of the Cervix
Authors: Barakovic Amna , Jahic Mahira , Cerovac Anis , Hadzimehmedovic Azra
Published: August 2022

Background: Vaginal microflora plays an important role in cervical carcinogenesis. An increase in vaginal pH is associated with the severity of squamous intraepithelial lesion (SIL) and a decrease in the number of lactobacilli. Microbial dysbiosis contributes to the damage of the epithelial barrier, as well as the reprogramming of immune and metabolic signaling. Dysbiotic bacteria cause damage to the epithelial barrier, immune dysregulation and genotoxicity and create a tumor-permissive microenvironment. Objective: The aim of this study was to determine the presence of risk factors (abnormal colposcopic and microbiological status, elevated pH of the vaginal environment) in regular Pap tests and LSIL. Methods: Retrospective prospective study 2021-2022. 90 women with pap smears were analyzed: 40 with LSIL at the Gynecological Center “Dr. Mahira Jahić” Tuzla and 50 with normal findings at the Tesanj Health Center. General data such as: age of the subjects, reproductive status, contraception, smoking and data on colposcopic examination, microbiological findings and vaginal pH value were analyzed. Statistical data processing was done in the SPSS program. Results: The average age of the test subjects is 39.94, in normal Pap 41.20 years, and in LSIL 38.38 years. The vital characteristics of the subjects did not differ significantly, except for smoking, where in LSIL findings, they consumed cigarettes significantly more often. Abnormal colposcopic examination were found in 85% (N-34) of women with LSIL. In subjects with LSIL, a positive microbiological test for enterobacteria was found in 47.5% (N-19) and a normal pap test in 12% (N-6). Statistically significant difference p=0.00523 p<0.05, E faecalis and E coli had the highest prevalence in LSIL. The mean pH value of the vaginal environment in LSIL is 5.38, and 4.96 in a regular pap test. Subjects with LSIL in 10% (N-4) had a normal pH test, and 48% (N-24) had a normal Pap test. P=0.00129 p < (0.05). A normal pH value was significantly more common in subjects with a normal Pap test. Microbiological flora, especially enterogenic bacteria, are more common in LSIL than in women with a regular pap test. Conclusion: when monitoring women with LSIL, special attention should be paid to the elimination of present enterobacteria (E.faecalis and E.coli) as a possible risk factor in the development of precancerous lesions (SIL) and cervical cancer.
Ameloblastoma: Pathogenesis, Clinical and Radiological Features, Classification, and Management
Authors: Aoun Georges
Published: August 2022

Background: Ameloblastoma are benign epithelial odontogenic tumors affecting the jaws. Objective: The main objective of this article is to review the pathogenesis, clinical and radiological features, classification, and management of ameloblastoma. Methods: A literature review mainly of the Pubmed database was done using the keywords: “ameloblastoma pathogenesis”; “ameloblastoma classification”; “ameloblastoma history”; “clinical and radiological features of ameloblastoma”; and “management of ameloblastoma”. Results: In 2017, ameloblastomas were classified by W.H.O into three categories: a) unicystic, b) conventional, and c) extraosseous/peripheral. Clinically, they are slow-growing, localized, aggressive neoplasms. Radologically, they mainly present as extensive, radiolucent, multilocular images, with a typical “soap bubble-like” appearance with a thinner, expanded, and eroded cortical plate. The linked non-erupted tooth is displaced and the roots of the adjacent teeth undergo clear resorption. Conclusion: Because of their late signs and symptoms, ameloblastomas are usually identified at an advanced stage. Their management typically includes a large resection with safety margins and immediate reconstruction when possible. Regular long-term postoperative follow-ups are mandatory for optimum treatment outcome and recurrence prevention.

Authors: Sulejmanpasic Gorana , Serdarevic Amra , Hajric Selma
Published: August 2022

Background: The VEPs provide an objective measure of brain function, analyzing integrity of visual processing. With patients affected with schizophrenia, the changes with the implementation of VEP are evident, such as symmetrical deceleration of the impulse (reduction of the amplitude) and the continuance of latency, which points to a degenerative illness, suggesting the presence of optical neuritis or hemianopsia conjoined with mentioned intracranial illness. Objective: The aim of the study was to determine the correlation of l P100 latency and P100 amplitude (µV) between patients with schizophrenia and patients with migraine headache. Visual evoked potentials (VEPs) were applied. Methods: The sample included 80 subjects: a) S group- 40 patients with schizophrenia (21 males; 19 females), b) H group-40 healthy subjects with migraine headache (10 males; 30 females). The study was conducted at the Department of Psychiatry, Neurology and Radiology, University Clinical Center Sarajevo. Results: Our research revealed positive correlations were registered in P100 latency in left view field of both eyes and in P100 amplitude in the region of right eye (p=0.01) in comparison with left eye region (p=0.05) in patients with schizophrenia. Conclusion: Results imply that the cognitive impairment seen in schizophrenia is not just due to deficits in higher order aspects of cognition but also encompasses significant deficits in early sensory processing. Our study is useful to initiate new questions and recommendations for further studies, specifically on changes in the occipital lobe in the schizophrenic patient’s brain. Changes in the volume in the occipital lobe are quite evident and further studies are required to better understand how the progressive brain changes affect the structural, functional, and metabolic activities of the occipital lobe in schizophrenia.

Published: August 2022

Moya Moya disease (MMD) is a rare cerebrovascular occlusive disorder resulting from progressive stenosis of intracranial blood vessels with secondary development of an anastomotic capillary network. Moya Moya is the Japanese term for puff of smoke appearance and it refers to the angiographic finding of a cluster of small abnormal blood vessels.
The classic paediatric presentation in this disorder is recurrent transient ischaemic attacks (TIA) and /or completed or repeated ischemic strokes. Medical treatment aimed at decreasing ischemic symptoms by using Vasodilators and anti-coagulants. The main stay of treatment includes direct and indirect surgical revascularisation procedures.
Risk factors for peri operative complications are history of TIAs, severity of disease, intraoperative hypotension, hypercapnia, hypovolemia, and significant reduction in haematocrit and circulating blood volume.

Background: Secretory carcinoma is a rare histological type of breast neoplasm in humans and dogs that is characterized by the presence of intracellular and extracellular eosinophilic secretions.
Case Description: In this case report, we describe the cytological, histological, and immunohistochemical characteristics of secretory mammary carcinoma in a 10-year-old mixed-breed female dog with nodal and bone metastases. The bitch had a history of claudication and a mass in the left humeral scapular region, which revealed osteolysis of the proximal humerus on radiography. Fine-needle aspiration cytology revealed numerous neoplastic cells arranged mostly in cohesive groups, but sometimes isolated, that contained cytoplasmic vacuoles and had a moderate to high nucleus: cytoplasm ratio with frequent karyomegaly and evident nucleoli. Histologically, the neoplasm was organized in solid, tubular structures with luminal spaces filled with eosinophilic secretions and was composed of cells with clear cytoplasm and prominent vacuoles that pushed the nuclei to the periphery, resembling signet ring cells. The extracellular and intracytoplasmic material of the epithelial cells was positive for periodic acid-Schiff (PAS) staining and immunoreactive for alpha-lactalbumin. Two chemotherapy sessions were performed, but one month after surgery, the clinical condition worsened, and euthanasia was elected, accounting for 133 days of survival after surgical removal of the tumor.
Conclusion: The bitch presented with secretory mammary carcinoma with nodal and bone metastases, and histological and immunohistochemical characteristics were important for diagnosis. The morphological and immunohistochemical characteristics of this carcinoma were similar to those observed in humans. Mammary gland secretory carcinoma with bone metastasis must be included as a differential diagnosis among canine mammary gland carcinomas showing cellular morphological characteristics of intracytoplasmic vacuolization and eosinophilic secretion.

Published: August 2022

Indonesia receives a lot of sunlight throughout the year. This then causes large profits to be obtained with the Development of a Solar Power Plant Planning (PLTS) that uses a photovoltaic (PV) system. This research then aims to look at how the use of PV systems as a solar power generation system becomes alternative energy in the future. The approach used in this research is a qualitative approach through a literature study of various previous studies and studies that discuss the planning of PV-type solar PV in Indonesia. This study found that the PLN network can be integrated and benefit PLTS that are on-grid and use solar modules. Then various public facilities with a flat surface and wide enough can be a good enough place to be a PV type PV mini-grid. Then the ratio of power that PLN has issued for PJU is 76.66%, while the ratio of solar panels is 23.3%. Unfortunately, the main ingredients for making PV mini-grid are still imported, which makes it challenging to develop PV-type PV mini-grid.

Published: August 2022

The Covid-19 pandemic that struck the world in December 2019 has connected people globally through the media. Now man is more aware of the surroundings and happenings worldwide. And the age group that is taking the most advantage of the virtual world is the youth.Before the pandemic the youth was engaged in the traditional methods of classroom studies, whereas the imposed lockdowns have opened new windows for their overall development. The study highlights that, in the time of Covid-19 the students of technical education were made aware of the different ways of learning methods other than the traditional classroom method. They were exposed to the internet and hence came across the different ways and methods of learning. Frequent virtual seminars, conferences, trainings and workshops were organized for the students by their respective educational institutes where they were given guidance not only from local experts but also from international experts too. This phenomenon brought positive changes in the overall development of the learners and also provided a broader spectrum to the teachers. This research lays emphasis on the two different streams of technical education which are 1) Fashion Design and 2) Interior Design. These streams are more practical oriented streams of technical education.The impact of the online teaching and learning on these fields is discussed in detail in this research. In this pandemic period the students of these disciplines got more insight of the designs acclaimed not only at national levels but also at the international levels.But on the other hand, due to the online classes the students were deprived of the practical knowledge and finesse that they gain in their subject related laboratories. The study deals with the effect of the pandemic on the overall academics of these design students.

Published: August 2022

Magnetic nanoparticle CoFe2O4-based hyperthermia is a promising non-invasive approach for cancer therapy. However, CoFe2O4 nanoparticles (NPs) have a low heat transfer efficiency, which limits their practical clinical applications. Hence, it is necessary to investigate the higher-performance magnetic NPs-based hybrid nanostructures to enhance their magnetic hyperthermia efficiency. This work presents a facile in situ approach for synthesizing cobalt ferrite (CoFe2O4) silver (Ag) hybrid NPs as optical-magnetic hyperthermia heat mediators. The prepared cobalt ferrite silver hybrid NPs exhibit a higher heat generation than that of individual Ag or CoFe2O4 NPs under simultaneous exposure to an alternating current magnetic field and laser source. The obtained results confirm that the hybridization of CoFe2O4 and Ag NPs could significantly enhance the hyperthermia efficiency of the prepared NPs. Therefore, the CoFe2O4-Ag hybrid NPs are considered as potential candidates for a high-performance hyperthermia mediator based on a simple and effective synthesis approach.

This article proposes a solution to improve office chairs (referred to as IoT chairs) based on IoT technology and LSTM (Long Short – Term Memory) neural networks to monitor and promptly warn via the Internet about questions of abnormal health status of office staff. An IoT circuit with the MCU-ESP8266 module is used to collect weight and an accelerometer sensor embedded in the chair, which can communicate with a computer to monitor the searing time of the user and warn by sound for prolonged sitting. LSTM neural networks built on MATLAB is trained by deep learning techniques to track inappropriate postures of people sitting in chairs, through analyzing signals from sensors. Experiment results on many different scenarios show that the accuracy of capacity of reminding about the status of prolonged sitting is 100% and reliability of the capacity of detecting and warning abnormal health conditions is 94%. Experiments also show that the ability to complete IoT chairs for a popular application is completely feasible.

Background and objectives: Rotavirus is a significant cause of nonbacterial diarrhea, especially in infants and young children worldwide. This study evaluated the pattern of rotavirus infection in children under five years presenting with acute diarrhea in Abuja Teaching Hospital, Gwagwalada, Nigeria. Methodology: It was a cross-sectional descriptive study to describe the prevalence of rotavirus infection among children. The study enrolled children 1 to 59 months old with acute diarrhea attending General Paediatric Outpatient clinic and hospitalized in the Emergency Paediatric Unit of University of Abuja Teaching Hospital (UATH), Gwagwalada, Nigeria. Rotavirus antigen was detected in the stool by qualitative enzyme-linked immunosorbent assay (ELISA). Data were analyzed using IBM-SPSS version 25.0. Results: The study comprised of 414 diarrhoeal children aged 1–59 months, of which 226 (54.6%) were male and the mean age was 12.1 months. The overall rate of rotavirus infection was 43.0% (178/ 414). The rotavirus infection was slightly higher among females than in males (46.8% vs 39.8%; p=0.153). Children from upper and middle social classes were at 1.95 [CI=1.17–3.26] and 3.08[CI=1.77–5.34] times higher risks of rotavirus induced diarrhea than the children from the lower social class (p<0.005). Children whose mothers had post-secondary education were three times more at risk of rotavirus diarrhea [OR=3.70; CI=1.46–9.36] than those with primary or no formal education (p<0.05). Children who had never been vaccinated against rotavirus were four times more likely to suffer rotavirus infection than those who had been vaccinated [OR=3.96; 95%CI=1.13–13.89, p=0.032]. Conclusion: This study found that rotavirus was an important causative agent of diarrhea in children in Gwagwalada, Abuja. Due to low rotavirus vaccination status in children, rotavirus screening tests are necessary for children with acute diarrheal disease. J Med Sci. 2022; 16(2): 010.

The issue of increasing NPA is alarming for the banks. There is great essence of finding solution to this situation when NPA is moving towards double digit. Large percentage of Priority sector lending has been found to turn into NPA, however the contribution of non-priority sector towards NPA is no less. The basic reason for the emergence of priority sector lending is to provide financial assistance to the priority sectors by providing priorities in taking loans. The Government always looks at the wider prospects of the country. When the Government wants the development at large, it promotes the schemes which is supposed to be implemented at large let it be medical facilities, job opportunities, government schemes for unprivileged, the senior citizens, and so on.
Webcam Based Gesture Detection and Recognition to Navigate in the Application
Authors: Journal IJSREM
Published: August 2022

— Most e-commerce websites do not provide their users an engaging purchasing experience. The buyer can only watch images or videos of the product that he or she wishes to buy; there is no method for the buyer to virtually interact with the product. Secondly, e-commerce websites can be difficult to use for the disabled and elderly, who are less familiar with latest technology. Thus, the purpose of this research was to provide fast and time efficient code-based solution that will allow people who are unfamiliar with new technologies to use websites and apps using dynamic hand gestures. It is a live project that will be utilized for shopping on the firms' e-commerce websites. We used Pytorch, a machine learning library, to create the gesture detection and recognition system which is capable of recognizing and detecting various human gesture, such as swiping up hand, swiping down hand, turning fist clockwise, etc. All of these motions are pre- linked to various sorts of tasks. The images of these gestures were utilized to train and develop a machine learning model, which, when applied, recognized and executed the pre-linked functions for the taught human gestures.

ABSTRACT The paper entitled “Students’ Error in Constructing Complex Sentences” is aimed to find out the error that students make in constructing complex sentences in interrogative form with the noun clause as dependent clause. In conducting this research, the writer applies descriptive method to describe the students’s error. The research was conducted in the fifth semester students of English Education Study Program, Faculty of Teacher Training and Educational Sciences, Pakuan University. The writer uses purposive sampling in conducting this research and takes the students who got score less than 70 in Text Based Structure.  The data were gained from three instruments: documentation, questionnaire and interview. The documentation is taken from the students’ work, questionnaires are distributed to the 60 students who become the participants and the interview is done to the lecturer who taught Text Based Structure. The writer finds out there are four types of error that students made. Those errors are omission, addition, misformation and misordering. The result shows that the highest error made by students is misformation. The writer suggests that the students should learn more about the pattern of complex sentence so they will know the verb that should be used in the noun clause as dependent clause. Keywords : students’ error, complex sentence, noun clause

Published: August 2022

Vocabulary is an English basic need that is required in the learning process. Through vocabulary, people can express their ideas. In fact, the students still get some difficulties when they learn vocabulary, especially for young learners. Young learners are supposed to be the children who study at the first year of formal schooling. They are kindergarten students in 4 years old and elementary students who are 6-12 years old. This research is conducted at SDIT Bening to find out the effect of using whole language approach on young learners’ vocabulary enrichment. In this research, pre-experimental method with one group pre-test post-test is used. 22 students are taken as the sample. Some statistical calculations are done to analyze the data and t-test formula is applied to get the final result. Based on the data calculation, the t-test value is 3.22. The result of t-calculated and t-table with d.f = 21 at significant level 0.01 is 2.83 and significant level of 0.05 is 2.08. It shows that the value of t-calculated is higher than t-table (3.22more than 2.83 more than 2.08). It means that the alternative hypothesis (Ha) is accepted. Therefore, it can be concluded that there is an effect of using whole language approach on young learners’ vocabulary enrichment. Keywords: whole language approach, young learners, vocabulary enrichment.
