Authors: Xu Wei ,   for the Alzheimer’s Disease Neuroimaging Initiative, Tan Chen-Chen , Zou Juan-Juan , Cao Xi-Peng , Tan Lan
Published: May 2021

Background: It is suggested that not all individuals with elevated Aβ will develop dementia or cognitive impairment. Environment or lifestyle might modulate the association of amyloid pathology with cognition. Insomnia is a risk factor of cognitive disorders including Alzheimer’s disease. Objective: To investigate if insomnia moderated the relationship between amyloid-β (Aβ) and longitudinal cognitive performance in non-demented elders. Methods: A total of 385 Alzheimer’s Disease Neuroimaging Initiative participants (mean age = 73 years, 48% females) who completed 4 + neuropsychological evaluations and a [18F] florbetapir positron emission tomography scan were followed up to 8 years. Linear mixed-effects regression models were used to examine the interactions effect between insomnia and Aβ on longitudinal cognitive sores, including four domains (memory [MEM], executive function [EF], language [LAN], and visuospatial function [VS]). Results: The Aβ-positive status (A+) but not insomnia independently predicted faster cognitive decline in all domains. Furthermore, the relationship between Aβ and cognitive decline was moderated by insomnia (MEM: χ2 = 4.05, p = 0.044, EF: χ2 = 4.38, p = 0.036, LAN: χ2 = 4.56, p = 0.033, and VS: χ2 = 4.12, p = 0.042). Individuals with both elevated Aβ and insomnia experienced faster cognitive decline than those with only elevated Aβ or insomnia. Conclusion: These data reinforced the values of insomnia management in preventing dementia, possibly by interacting Aβ metabolism. Future efforts are warranted to determine whether sleep improvement will postpone the onset of dementia, specifically among populations in stages of preclinical or prodromal AD.

Published: May 2021

Background: There is significant interest in understanding the role of modifiable vascular risk factors contributing to dementia risk across age groups. Objective: Risk of dementia onset was assessed in relation to vascular risk factors of hypertension and hypercholesterolemia among cognitively normal APOE ɛ4 carriers and non-carriers. Methods: In a sample of prospectively characterized longitudinal cohort from the National Alzheimer’s Coordinating Center database, 9,349 participants met criteria for normal cognition at baseline, had a CDR-Global (CDR-G) score of zero, and had concomitant data on APOE ɛ4 status and medical co-morbidities including histories of hypertension and hypercholesterolemia. Multivariable Cox proportional hazards models adjusted for well-known potential confounders were used to compare dementia onset among APOE ɛ4 carriers and non-carriers by young (≤65 years) and old (> 65 year) age groups. Results: 519 participants converted to dementia within an average follow up of 5.97 years. Among older APOE ɛ4 carriers, hypercholesterolemia was related to lower risk of dementia (HR (95% CI), 0.68 (0.49–0.94), p = 0.02). Among older APOE ɛ4 non-carriers, hypertension was related to higher risk of dementia (HR (95% CI), 1.44 (1.13–1.82), p = 0.003). These results were corroborated among a subset with autopsy data characterizing underlying neuropathology. Among younger participants, vascular risk factors did not impact dementia risk, likely from a lower frequency of vascular and Alzheimer’s as etiologies of dementia among this cohort. Conclusion: A history of hypercholesterolemia related to a lower risk of dementia among older APOE ɛ4 carriers, while hypertension related to a higher risk of dementia among older APOE ɛ4 non-carriers.

Published: May 2021

BACKGROUND:

Clostridium difficile Infection (CDI) can lead to diarrhea and fulminant colitis. C. difficile infects the host using toxins. Recent studies report prevalence of CDI in the small intestine. Berries are known to contain antioxidants and phenolic compounds that might mitigate bacterial infection.

OBJECTIVE:

We explored the impact of C. difficile toxins on the small intestine using an in vitro approach and used systems biology techniques together with data integration to identify food compounds that can reduce their cytopathic impact.

METHODS:

Differentiated Caco-2 cells were exposed to C. difficile toxins and the transcriptomic changes were studied. To identify foods with potential beneficial counteracting effects, the transcriptomic profiles were integrated with transcriptomics data from Caco-2 cells exposed to various food compounds and analyzed using multivariate analysis.

RESULTS:

Beneficial food candidates, selected by multivariate analysis, such as blackcurrant, strawberry and yellow onion were further examined for their potential to counteract the effect of the toxin-induced disruption of cell integrity and toxin translocation. Our results confirmed effects of food compounds, on the cytopathic effects of toxins in the small intestine.

CONCLUSION:

Blackcurrant, strawberry and yellow onion can counteract C. difficile toxins induced effects.

Authors: Agrawal Rahul , Bajaj Preeti
Published: May 2021

Brain-Computer Interface provides and simplifies the communication channel for the physically disabled individuals suffering from severe brain injury related to brain stroke and lost ability to speak. It helps these patients to connect with the outside world. In the proposed work, the electroencephalogram signal is used as an input source taken from Bonn University database that is divided into three class of data consisting of 247 samples each. It is further processed by Tunable Q-Wavelet Transform signal decomposition technique where the signals are subdivided into various sub-bands depending on the value of Q-factor, redundancy factor, and number of sub-bands. A novel custom technique uses Q-factor of 3, redundancy value of 3 & 12 number of sub-bands for high pass filtering as well as Q-factor of 1, redundancy value of 3 & 7 number of sub-bands for low pass filtering combined with nine statistical measures for feature extraction purpose. The classification is performed by using multi-class support vector machine giving the accuracy of 99.59%. The accuracy performs best when compared with the existing research results Furthermore, the comparative study has been performed on the same dataset by using deep neural network along with support vector machine giving an accuracy of 100%. Other evaluation parameters such as precision, sensitivity, specificity, and F1 score are also calculated. The classified data help transform the signal into three communication messages that will help solve the speech impairment of disabled individuals.
Intelligent recognition of dance training movements based on machine learning and embedded system
Authors: Zhang Dixin
Published: May 2021

Recognizing human movement is an important research topic in the field of human-computer interaction, and people expect it to be used in smart homes, virtual reality, and electronic games. Based on the interaction between humans and computers, more and more attention has been paid, especially in the field of smart home action recognition. Through observation, people can understand the intention of intelligent interaction is included in the main part. However, the current recognition algorithms still cannot meet the actual requirements of the accuracy, real-time and robustness of human motion recognition. Especially in order to recognize complex human movements in real time, it is imperative to solve several problems in motion capture and recognition. Establishing the feature parameter angle of the feature vector space of motion data, using the pre-recognition algorithm is based on multi-class support vector machines. The motion recognition algorithm takes advantage of the accurate and fast classification function of svm. Based on the structural differences of the motion data, most of the data can be correctly identified. The optimal motion recognition algorithm uses hmm to correct the svm error recognition result through the random constraint relationship between the error recognition data and the actual label. Based on data simulation and analysis, each variable determined by the grid search algorithm has the highest accuracy in the optimization of each variable of the support vector machine. Finally, a smart home simulation experiment interactive system was built, and a local database was created, including 1,300 processes. The real-time algorithm uses the data in the local database for training and testing. Experimental results show that the motion recognition algorithm in this paper improves the accuracy and robustness of complex motion recognition. While meeting the real-time recognition conditions, the correct answer rate of the final operation can reach 9.6%. The human motion trajectory recognition system uses the three-dimensional trajectory of gestures to recognize motion. The information in the three-dimensional space is more comprehensive, and the orbit recognition is more robust.
Two-stage stochastic integrated adjustment deviations and consensus models in an asymmetric costs context
Authors: Li Huanhuan , Ji Ying , Qu Shaojian
Published: May 2021

Decision-makers usually have a variety of unsure situations in the environment of group decision-making. In this paper, we resolve this difficulty by constructing two-stage stochastic integrated adjustment deviations and consensus models (iADCMs). By introducing the minimum cost consensus models (MCCMs) with costs direction constraints and stochastic programming, we develop three types of iADCMs with an uncertainty of asymmetric costs and initial opinions. The factors of directional constraints, compromise limits and free adjustment thresholds previously thought to affect consensus separately are considered in the proposed models. Different from the previous consensus models, the resulting iADCMs are solved by designing an appropriate L-shaped algorithm. On the application in the negotiations on Grains to Green Programs (GTGP) in China, the proposed models are demonstrated to be more robust. The proposed iADCMs are compared to the MCCMs in an asymmetric costs context. The contrasting outcomes show that the two-stage stochastic iADCMs with no-cost threshold have the smallest total costs. Moreover, based on the case study, we give a sensitivity analysis of the uncertainty of asymmetric adjustment cost. Finally, conclusion and future research prospects are provided.

Published: May 2021

BACKGROUND: Hemiparetic patients lose the ability to move their trunk selectively, abdominals are affected and neither voluntary nor reflex activity is present. OBJECTIVE: To investigate if the inclusion of specific exercises for the trunk muscles in a rehabilitation program for chronic hemiparetic patients could lead to an additional improvement. METHODS: A multiple-participant single-subject design was replicated in patients with hemiplegia. The study was conducted in two cycles: for the first cycle (A), patients received conventional rehabilitation program, then for the second cycle (B), six months later, the same subjects received conventional rehabilitation therapy plus an additional specific selective trunk muscles training. Trunk Impairment Scale (TIS), Berg Balance Scale (BBS), 10 meters distance walk test (10 MWT), Functional Independence Measure (FIM) and instrumental gait analysis were performed before and after both treatment cycles. RESULTS: Significant changes were observed in TIS and 10 MWT after the two treatment cycles. However, after treatment cycle B, BBS and FIM score showed an additional improvement. Whereas, after treatment cycle A gait analysis did not relevantly changed, but after cycle B a significant improvement was registered in velocity, cadence and percentage of stance in the gait cycle. CONCLUSIONS: In our patients, the training for selective activation of the trunk muscles had led to a consistent improvement of gait analysis parameters, and hemiparesis-related disability in stance and activities of daily living.
Experimental research of electrical characteristics combined solar-electric air heater
Authors: Pasichnyk P. , Gaba К. , Kyrychenko М.
Published: May 2021

The development and improvement of solar equipment is a necessary step in the development of solar heating systems. One of the ways to develop solar air heaters is to use new materials for the production of solar absorbers. This expands the possibility of using nozzle and capillary-porous materials in contrast to liquid solar collectors. Development and research of air heating systems with equipment made of modern textile materials is relevant. For the manufacture of absorbers it is advisable to use textile materials. This will reduce the cost of solar collectors, as well as reduce their weight and capital costs. The absorber meets requirements for both solar thermal collectors and electric heaters: high absorption capacity of solar radiation; developed heat transfer surface; relevant physical properties: low mass, resistance to ultraviolet radiation, thermal resistance, low cost for cheaper solar system; sufficient electrical resistance. A combined solar-electric air heater has been developed, which combines two main elements of any solar system – a solar heat collector and an additional heat source, the absorber of which is made of carbon graphite knitted fabric. This reduces its cost and mass and allows them to be used on existing heating facilities without the construction of bulky supporting structures to accommodate solar fields. The combined solar-electric air heater can be used as an independent heat generator for heat supply systems. To use the proposed solar-electric air heater, it is necessary to heat its absorber with an electric current, so the material from which it is made must be electrically conductive, but have sufficient electrical resistance. The use of carbon-graphite knitted fabric allows the use the direct heating of the solar energy absorber by electric current due to the corresponding electrical characteristics. This article presents the results of an experimental study of the electrical resistivity of carbon-graphite knitted fabric. These studies allow determining the electrical power of the device regardless of the size of the device. The research results presented in the article can be used only for a certain type of carbon graphite knitted fabric.

Authors: Tadaura Hiroko
Published: May 2021

Background: There are few biomechanical studies on the physical transfer of a person lying on a floor or bed perpendicular to the direction of gravity. Basic biomechanics research can be an important source. This study aimed to analyze the biomechanical properties of the upward movement of the floor in the supine position.

Methods: Healthy volunteers were recruited by snowball sampling. The movement from the supine position to upward movement on the carpet floor was repeated three times. The three procedures were analyzed with an 11 segments model using a 3D motion analysis Move Tr 3D (Library©) under the 4 CCD cameras. The analysis of the motion trace was examined. The movement of the reflection marker with respect to the Z-axis was analyzed with the vertical direction of the gravity as the Z-axis. It was observed from the XY plane, XZ plane, ZY plane, and how many dimensions the reflection marker took was analyzed.

Results: Five healthy volunteers (Medium age 27 years, Female) who received written consent to the study were investigated. A spiral motion was observed in the trajectory of all reflection markers. A walking motion was observed in which the right and left sides of the body alternately swam to the back. Each reflex marker body site was moving headward as if contacting the floor with either the left or right side having 0 to the vertical Z-axis of gravity; the opposite left or right side walked with repeated movements floating from the floor and raising the Z coordinate. 3D Space + 1D time were observed in the human fundamental upward movement.

In this study, we explore the changed spatiotemporal nature of mobility demand. Through a comparative analysis of New York City taxi records data, we observe how relative demand for taxis has displaced across land use zones and concentrated during daylight hours. We also find changes in payment methods that counter public health advice. These findings point to the fundamental mobility needs during the pandemic.
An experimental method to study the absorption capacity of paper towels
Authors: ABEDSOLTAN HOSSEIN
Published: May 2021

This study proposes an experimental method for the in-plane liquid wicking to determine the absorption capacity of retail paper towels. Individual plies of the paper towels were tested to minimize the transverse wicking effects on surface wetting. The method involves arbitrary point source injection of liquid into the paper towel surface while recording microscopic images of the wetted areas as liquid spreads. The samples were selected from two main manufacturing processes: conventional wet pressing and through air drying. The tested liquids were water and decane with various driving forces. Two distinct imaging systems, infrared light absorption imaging and visible light transmission imaging, monitored and recorded the wetting process. The wetted regions were calculated to generate the wetting graphs, which illustrate both the dynamic and static wetting behaviors.It was found the amount of driving force has a negligible effect on the maximum wetted area formed on the surface.So, the maximum wetted area and the paper grammage were applied to determine the absorption capacity of the tested towels. Moreover, the absorption capacity results were validated by the basket-immersion test method (ISO 12625-8).Therefore, the proposed method in this work enables quantification of the absorption capacity of papertowels.

Published: May 2021

Radiology interfaces with all medical disciplines. Whether medical students pursue a career in radiology or any other medical discipline, as future physicians they will always come across imaging at multidisciplinary conferences (MCs). Students at all departments are confronted with imaging in their studies. It is therefore important they recognize the role of radiology in patient care. With imaging being imperative for patient management, radiology is indispensable at MCs. Radiologists cooperate with all clinical departments, and are often final to be asked for decisions at MCs. Joining MCs can prepare students for image interpretation and demonstration in their future clinical practice. MCs can complement to teaching in busy clinical routine. MCs embody educational grounds of lifelong medical learning for radiologists and other physicians. As medical students are going to enter a profession of lifelong learning, MCs can likewise offer valuable educational opportunities. The article presents three reasons to seize MCs as potential teaching opportunities for medical students in radiology: 1. the significance of radiology for MCs; 2. preparation of medical students for MCs; and 3. exploration of MCs for lifelong learning.
Creating Culture Circles- A Case of Continuing Professional Development Workshop for Israeli Special Education Teachers
Authors: Reingold Roni , Dery Keren , May Nira
Published: May 2021

The focus of critical educational philosophy is not only on criticising traditional education (Banking education), but also on promoting a pedagogy for liberation, whereby education is a cultural action for freedom. The main strategy or tool of critical pedagogy is the culture circle, a dialogical problem-posing method of education. The current qualitative case study examined the use of culture circles in a continuing professional development workshop for Israeli special education teachers. Given the over-representation of culturally and economically oppressed populations in the special education system, it would be appropriate to raise the awareness of the SE teachers of this situation. Findings revealed that while developing culture circles during the workshop, most of the teachers moved from proposing hurried and shallow solutions, to offering carefully thought-out ideas for joint analysis, following an in-depth review and definition of the problem. Despite starting the process with an idealised perception of society and an over-inflated sense of self-efficacy, when group participants completed the workshop, they had acquired the ability to acknowledge and even contend with the unjust conditions and imperfections of the Special Education System. It seems that, participating in culture circles can help teachers to both understand their current realty fully and deeply and to set meaningful goals for the future.
CÂBİRÎ’NİN EPİSTEMOLOJİK YENİDEN YAPILANMA PROJESİNİN YAPI BOZUMU
Authors: KESKİN İbrahim
Published: May 2021

Özet

Muhammed Âbid el-Câbirî, Arap/İslam kültürü üzerine yapısalcı analizleri ve yapı bozum çalışmaları ile tanınmış bir düşünürdür. Post sömürge dönemi aydını olarak Câbirî’nin çalışmalarının ana teması onun kriz durumu olarak nitelendirdiği geri kalmışlık sorunu olmuştur. Câbirî kriz durumunu aşmaya yönelik Arap/İslam kültürünün yeni bir okumasını önerir. Onun bu önerisi, Arap/İslam düşüncesinde bilimsel gelişmeleri sağlayacak yeni bir epistemolojik metodoloji inşa etmeye matuftur. Arap/İslam kültürel mirasını yapısalcılık aracılığıyla analiz eden Câbirî, homojen bir bütünlük olarak gördüğü geleneği yapı bozuma tabi tutarak eleştirmiş ve geleneğin ideolojik olarak inşa edildiğini göstermek amacıyla rasyonalite lehine değersizleştirmiştir. Fakat onun yapı bozumu geleneğin topyekûn yadsınması anlamına gelmez. Câbirî’nin Yeniden Yapılanma olarak ifade ettiği metodolojik inşa Arap/İslam aklının rasyonel unsurlarının yeniden keşfi ve evrensel akılla ilişkili olarak yapılandırılmasını ifade eder.

Bu makalede, Câbirî’nin söz konusu önerisinin yapı ve akıl özelinde Derrida’cı yapı bozum çerçevesinde eleştirisi amaçlanmaktadır. Bu eleştiri yoluyla Câbirî’nin yapı olarak analiz ettiği bütünlüğün bir kurgu olduğu ve bu kurgudaki teorileştirme girişiminin, birçok faktörün ihmal edilişi ve bu faktörlerin oyunu olarak nitelendirilebilecek bir sonucun, teorileştirmeye kurban edildiği ifade edilecektir. Ayrıca Câbirî’nin evrensel akıl olarak gördüğü akıl kabulüyle Batı metafizik geleneğinin özcülüğü ve logosentrizmine eklemlendiğinin açığa çıkarılması hedeflenmiştir. Câbirî’nin yeniden yapılanma projesi Batı metafizik geleneğine eklemlenme suretiyle söz konusu geleneğe içkin bütün problemlere malul görünmektedir.
Epichloë endophytes – new perspectives on a key ingredient for resilient perennial grass pastures

The confirmation that Epichloë endophytes are important for pest resistance in New Zealand pastures led to the development of a range of novel endophyte strain × host plant combinations that enhance the persistence of the grass, while mitigating adverse effects on grazing animals. Successfully delivering these endophytes to the pastoral industry has required the development of a range of scientific and commercial capabilities. In March 2012, the New Zealand proprietary seed industry established the Endophyte Technical Committee. This is a cooperative forum to ensure that endophyte strains in commerce or under development are tested uniformly, and to publish industry-agreed descriptions of the animal safety and insect control of commercial endophyte strains each year.
The role of Epichloë grass endophytes during pasture renewal
Authors: Hewitt Kati , Matthew Cory , McKenzie Catherine , Mace Wade , Popay Alison
Published: May 2021

The literature on the importance of Epichloë grass endophytes during pasture renewal is reviewed. Perennial ryegrass endophyte strains such as AR1, NEA2, and Standard Endophyte (SE) as well as tall fescue and meadow fescue endophytes, significantly increase seedling survival at establishment under insect pressure, for example from adult Argentine stem weevil, grass grub, and African black beetle. However, in endophyte-infected ryegrass, insect-derived plant damage increases 10–43 days after sowing despite the presence of endophyte. Insecticidal seed treatments can mitigate the vulnerability to insect predation during this time.
Cell Surface Area to Volume Relationship During Apoptosis and Apoptotic Body Formation.
Authors:   Institute of Biomedical Research of Salamanca (IBSAL), Salamanca, Spain, López-Hernández Francisco J.
Published: May 2021

Apoptosis is a programmed form of cell death culminating in packing cell content and corpse dismantling into membrane sealed vesicles called apoptotic bodies (ABs). Apoptotic bodies are engulfed and disposed by neighboring and immune system cells without eliciting a noxious inflammatory response, thus preventing sterile tissue damage. AB formation requires a total surface area larger than the apparent, initial cell's surface area. Apoptotic volume decrease (AVD) is a two-stage process leading to an isotonic, osmotic reduction in cell water content driven by net K+ and Cl- extrusion. In this article, the role of AVD is presented from a geometric point of view through the process of AB formation. AVD decisively contributes to (i) endowing the cell with the appropriate electrolytic environment for apoptotic execution; (ii) increasing the membrane surface area-to-volume ratio, along with the mobilization of membrane reservoirs (cell rounding, membrane folds and endosomal membranes), so that the cell corpse can be dismantled into ABs; and (iii) reducing plasmalemmal stretch, tension and stiffness, thus facilitating membrane bulging, blebbing and vesicle expansion ultimately leading to separation and release.
My Enemy, My Neighbour: Characteristics and Challenges of Arabic Instruction in Israeli-Jewish Society
Authors: Amara Muhammad
Published: May 2021

This article examines Arabic instruction in Israeli Hebrew schools with regard to the political, social, cultural, historical and pedagogical issues shaping it. It examines challenges facing Arabic instruction in Israel's education system, emphasising the dissonance between potential benefits of studying Arabic and its overall marginalised status in Israel. This article argues that that the main factors shaping Arabic instruction in Israeli-Jewish schools since 1948 are official security considerations and security claims — Arabic is studied as the language of the enemy and not the neighbour. A radical policy shift is required to ‘civilianise’ and demilitarise Arabic instruction and transform it into a bridge for understanding between Israeli-Jews, Palestinian-Arab citizens of Israel, in particular, the Palestinians, in general, as well as Israel's Arab neighbours in the Middle East.
Travel Literature, Pilgrims and Missionaries: A Mid-Nineteenth Century Duel Over the Holy Land
Authors: Saliba Issa A.
Published: May 2021

The image of the Holy Land/Palestine and special affinity among Protestant Americans in the first half of the nineteenth century, a period which has received relatively little religious analysis, was directly influenced by the Bible, but also by inaccurate descriptions of travellers in the region. This fact is illustrated by sharp exchanges between two Holy Land enthusiasts, James Silk Buckingham and Eli Smith. Their disagreements in describing famous places fed into divergent narratives about Palestine, one romantic and the other more realistic, both of which, however, were manipulated by the future Zionist enterprise to assert Jewish claims and ascendancy.
Beardsley Men in Early Twentieth-Century Russia: Modernising Decadent Masculinity
Authors: Dovzhyk Sasha
Published: May 2021

This article explores the reception of the Decadent artist Aubrey Beardsley (1872–1898) in Russia concentrating on new gendered meanings acquired by ‘Beardsleyism’ in modernist Russian culture. While the so-called ‘Beardsley Woman’ became a widely discussed literary construct and journalistic trope in Britain, the imagination of Russian artists and literati was captured by a ‘Beardsley Man’. Due to the circulation of the artist's portraits and descriptions by modernist periodicals such as Sergei Diaghilev's Mir iskusstva (1899–1904), a specific form of male (self-)representation emerged in the homophile art circles of St Petersburg and Moscow. Exploring this new urban Russian masculinity, I use the case studies of four men who were compared to Beardsley or used Beardsley as a model in their work and self-fashioning: artist Nikolai Feofilaktov, poet Georgii Ivanov, writers Mikhail Kuzmin and Iurii Iurkun.
‘Puppet of skeletal escapade’: Dance Dialogues in Mina Loy and Carl Van Vechten
Authors: Girdwood Megan
Published: May 2021

In an undated letter, likely composed in late 1914, Mina Loy reflected on the recent aesthetic experiences that had greatly affected her, writing that the ‘things that have made [her] gasp were a few Picassos, Windham [ sic] Lewis, Nijinski dancing – perfection is infrequent’. The letter was addressed to her American agent Carl Van Vechten, a dance and music critic at the New York Times, who played a highly influential role in shaping discourses around ballet and modern dance both in the US and internationally. This article conjoins Loy and Van Vechten's modernist oeuvres – crossing genres including poetry, novels, newspaper reviews, and photography – in order to reveal the importance of dance to their shifting aesthetic commitments and shared interest in the expressive capacities of the human form. Dancing bodies, moving fluently across the work of this modernist pair, variously transcribe Futurist satires, Decadent revivals, and a primitivist fascination with the erotic aspects of dance, crystallising in Loy and Van Vechten's responses to the Harlem Renaissance.

IMPROVING THE ORGANIZATION IMAGE THROUGH THE SERVICE QUALITY AND COMMUNITY RELATIONSHIP EFFECTIVENESS ON PRIVATE JUNIOR HIGH SCHOOLS AT SUKAMAKMUR, KABUPATEN BOGORThe educational institution has changed into profit industrial institutions as the impact of era change. The proliferation of educational institutions has created competition for education service providers, both private and public schools. This competition is absolute and is getting tighter, especially for private educational institutions. To win the competition, school should build a positive image on all stakeholders.  On the contrary, at Sukamakmur District, it is found that the school image is still relatively low. This research aimed to improve school organizational image by analyzing its relationship between service quality and public relations effectiveness. The research was taken in private junior high schools in Sukamakmur District Bogor Regency. The study population was 385 students of grade 9 of 2019-2020 Academic Year. The sample taken was 196 students by using proportional random sampling. The data was collected by using a questionnaire with a scale (Rating Scale). The analysis technique used a survey method and a correlational approach. The results showed that there was a relationship between service quality and organizational image (ry1 = 0.785). There was a relationship between public relations effectiveness and organizational image (ry2 = 0.401), There was a relationship between service quality and public relations effectiveness on organizational image (ry12 = 0.794). It can be concluded that the organization image could be improved by service quality and public relations effectiveness partially or collectively
