This study aimed to analyze the value chain mapping, governance, improvement of value chain and marketing margins cassava in Pati regency. The basic method used  descriptive analytical research. The method of determining the location of the research method and the purposive sampling method is done by snowball sampling with 18 respondents. The results showed there are three models of the value chain by five actors, namely farmers, penebas, grinders, realtor, and collectors flour. Value-added activities conducted on cassava farmers, grinders and collectors. While penebas and brokers act as a liaison between value chain actors. Governance cassava value chain is analyzed through three approaches namely coordination structures, rules and regulations, and provider of information and services. The increase in the value chain are identified in several aspects of increase of processes, products, and functions. Enhanced functions effectively needs to be done because it will produce a positive impact on the actors of the value chain. Grinder has a marketing margin of RP 3300 / kg, meaning that most large margin than other players because it has many activities ranging from wet to cassava starch that have added value. While the perpetrators of broker only has a margin of RP 20 / kg for his activities only as an intermediary without any added value from the starch itself.

Fresh milk is highly nutritious food because its contain substances that complete food. The high nutritional value of milk causes a media which is preferred by the microorganisms to grow and develop in a very short time become unfit milk consumed when handled incorrectly. Safety milk from contamination during the distribution process becomes very important because of a race against time. Considering the conditions on the farm people milk distribution process normally without treatment (cooling), so that the required distribution by the shortest route, the fastest time and low cost. This study aims to minimize lines and distribution costs of fresh milk as marketing efficiency efforts. The research location is taken purposively based on the consideration that the District Mojosongo has the second largest population of dairy cows in Boyolali. The analytical method used is the analysis of marketing costs, margins and profit marketing, marketing efficiency and Traveling Salesman Problem analysis to determine the shortest distance, fastest time and lowest cost. Fresh milk marketing channels used dairy producers in the district Mojosongo there are three channels following the channel I: Farmer to Consumer, Channel II: Farmers to Traders collector to Consumer and Channels III: Farmers to Traders collector to wholesaler to the milk processing industry. Channel I is the most efficient marketing channel because this channel sells directly from farmers to consumers. The most effective marketing channels using the Travelling Salesman Problem is the distribution channels II because this path has the shortest distance, fastest time to maintain the quality of fresh milk and cost efficiency.

The results showed in Kulon Progo Regency soybeans planted in irrigated land, rainfed lowland and upland, adjust the availability of water. Soybean production technology is not implemented by farmers as a whole, depends on the conditions of agro-ecosystems and agricultural inputs. In general, farmers agree with soybean production technology components with the approach of integrated crop management (ICM). Some farmers do not agree with the manufacture of drainage, mulching straw and harvest when 95% of the leaves have yellowed. Varieties Detam-2, Ijen and Tanggamus more adaptive and give higher yields. However, soybean farmers in Kulon Progo Regency prefer largely seeded soybean as Argomulyo and Burangrang.

Banana (Musa spp.) is a tropical fruit that is widely grown in Indonesia as it beneficially increases the farmers’ welfare. However, the wider scale of suitable land still needs to be developed. This study aims to know the distribution of suitable locations for banana cultivation in Jenawi based on the climate conditions. The research was done by making soil map unit, characterizing land’s climate, matching climate conditions with plant growth requirements, and then mapping the suitable location for banana cultivation. The results showed that the agriculture’s climate suitability in Jenawi is classified into two areas: (1) middle - upper/eastern area (not suitable for banana cultivation as it is located in the high area of 2,056 masl with the low temperature 13.8°C and the high rainfall 3,750 mm/year); (2) middle - lower/west area (suitable for banana cultivation as it is located in the lower area of 610 masl with the higher temperature 22.6 °C and lower rainfall 3,333 mm/year. So that the banana plants are potentially developed in the middle - lower/west area of Jenawi i.e. in the Village of Trengguli, Sidomukti, Balong, Lempong, Menjing and Seloromo. The determination of the land suitability class in detail and in terms of the characteristics and quality of the soil can be more focused on the area which suitable climate conditions in order to obtain the land suitability class, limiting factors and improvement efforts.
A Semianalytical Model for Simulating Combined Electromagnetic Heating and Solvent-Assisted Gravity Drainage
Authors: Hu Lanxiao , Andy Li Huazhou , Babadagli Tayfun , Ahmadloo Majid
Published: March 2018

Solvent/thermal hybrid methods have been proposed recently to enhance heavy-oil recovery and to overcome the shortcomings that are encountered when either method is solely applied. One of the methods for this hybridization is to combine electromagnetic (EM) heating and solvent injection to facilitate heavy-oil production by gravity drainage. This approach has several advantages including reduced CO2 emissions, decreased water consumption, and appropriateness for water-hostile reservoirs. We are currently lacking any mathematical model for better understanding, designing, and optimizing this hybrid technique, which is partly attributed to this technique still being in its infancy.

We propose a semianalytical model to predict the oil-flow rate resulting from the combined EM heating and solvent-assisted gravity drainage. The model first calculates the temperature distribution within the EM-excited zone caused by the radiation-dominated EM heating. Using different attenuation coefficients within and beyond the vapor chamber, the model can properly describe the corresponding temperature responses in these regions. Next, an average temperature of the chamber edge contributed by EM heating is used to estimate the temperature-dependent properties, such as vapor/liquid equilibrium ratios (K-values), heavy-oil/solvent-mixture viscosity, and solvent diffusivity. Subsequently, a 1D diffusion equation is used to calculate the solvent-concentration distribution ahead of the chamber edge. Eventually, the oil-flow rate is evaluated with the calculated temperature and solvent distributions ahead of the chamber edge. The proposed model is validated against the experimental results obtained in our previous study, and the predicted oil-flow rate agrees reasonably well with the experimental data.

The proposed model can efficiently predict the oil-flow rate of this hybrid process. We conduct sensitivity analyses to examine the effect of major influential factors on the performance of this hybrid technique, including EM heating powers, solvent types, solvent-injection pressures, and initial reservoir temperatures. The modeling results demonstrate that a higher EM heating power, a heavier solvent, and a higher solvent-injection pressure could accelerate the oil-recovery rate, but tend to lower the net present value (NPV) and increase the energy consumption. In summary, the newly proposed model provides an efficient tool to understand, design, and optimize the combined technique of EM heating and solvent-assisted gravity drainage.

Firewall harus memberikan perlindungan terhadap malfeasants, sementara memungkinkan pengguna yang dipercaya untuk dapat terhubung. Sayangnya, tidak selalu mungkin untuk menyaring orang-orang jahat, karena penyaringan berdasarkan alamat IP dan port tidak membedakan pengguna yang terhubung. Orang-orang yang berniat jahat dapat berasal dari alamat IP terpercaya. Port terbuka tetap menjadi kerentanan: mereka mengizinkan koneksi untuk aplikasi tetapi juga dapat berubah menjadi pintu terbuka untuk serangan. Penelitian ini menyajikan suatu sistem keamanan baru, disebut port knocking, di mana pengguna terpercaya memanipulasi aturan firewall dengan mengirimkan informasi di seluruh port yang tertutup.

Published: March 2018

A tanulmány célja, hogy bemutassa a házassággal és az élettársi kapcsolattal összefüggő vélemények alakulását Magyarországon. Az elemzés során rámutatunk arra, hogy ugyan az elmúlt évtizedekben az élettársi kapcsolatokat a társadalom elfogadja, a házasság szerepe pedig csökkent, a többség továbbra is a házasságot tartja ideálisnak hosszú távon. Az elemzés során kitérünk arra is, hogy a fontosabb demográfiai, társadalmi jellemzők, különösen a családi állapot és a párkapcsolati helyzet milyen hatással vannak az élettársi kapcsolatok megítélésére, mely demográfiai csoportok támogatóbbak a házasság nélküli együttélésekkel szemben. Eredményeink szerint az életkornak, a párkapcsolati helyzetnek fontos szerepe van a vélemények alakulásában, de a párkapcsolat-történet nem minden esetben befolyásolja a házasságról kialakult nézeteket.

Co-Designing a Collaborative Chronic Care Network (C3N) for Inflammatory Bowel Disease: Development of Methods (Preprint)
Authors: Seid Michael , Dellal George , Peterson Laura E , Provost Lloyd , Gloor Peter A , Fore David Livingstone , Margolis Peter A
Published: March 2018

BACKGROUND

Our health care system fails to deliver necessary results, and incremental system improvements will not deliver needed change. Learning health systems (LHSs) are seen as a means to accelerate outcomes, improve care delivery, and further clinical research; yet, few such systems exist. We describe the process of codesigning, with all relevant stakeholders, an approach for creating a collaborative chronic care network (C3N), a peer-produced networked LHS.

OBJECTIVE

The objective of this study was to report the methods used, with a diverse group of stakeholders, to translate the idea of a C3N to a set of actionable next steps.

METHODS

The setting was ImproveCareNow, an improvement network for pediatric inflammatory bowel disease. In collaboration with patients and families, clinicians, researchers, social scientists, technologists, and designers, C3N leaders used a modified idealized design process to develop a design for a C3N.

RESULTS

Over 100 people participated in the design process that resulted in (1) an overall concept design for the ImproveCareNow C3N, (2) a logic model for bringing about this system, and (3) 13 potential innovations likely to increase awareness and agency, make it easier to collect and share information, and to enhance collaboration that could be tested collectively to bring about the C3N.

CONCLUSIONS

We demonstrate methods that resulted in a design that has the potential to transform the chronic care system into an LHS.
Peer-Based Social Media Features in Behavior Change Interventions: Systematic Review (Preprint)
Authors: Elaheebocus Sheik Mohammad Roushdat Ally , Weal Mark , Morrison Leanne , Yardley Lucy
Published: March 2018

BACKGROUND

Incorporating social media features into digital behavior change interventions (DBCIs) has the potential to contribute positively to their success. However, the lack of clear design principles to describe and guide the use of these features in behavioral interventions limits cross-study comparisons of their uses and effects.

OBJECTIVE

The aim of this study was to provide a systematic review of DBCIs targeting modifiable behavioral risk factors that have included social media features as part of their intervention infrastructure. A taxonomy of social media features is presented to inform the development, description, and evaluation of behavioral interventions.

METHODS

Search terms were used in 8 databases to identify DBCIs that incorporated social media features and targeted tobacco smoking, diet and nutrition, physical activities, or alcohol consumption. The screening and review process was performed by 2 independent researchers.

RESULTS

A total of 5264 articles were screened, and 143 articles describing a total of 134 studies were retained for full review. The majority of studies (70%) reported positive outcomes, followed by 28% finding no effects with regard to their respective objectives and hypothesis, and 2% of the studies found that their interventions had negative outcomes. Few studies reported on the association between the inclusion of social media features and intervention effect. A taxonomy of social media features used in behavioral interventions has been presented with 36 social media features organized under 7 high-level categories. The taxonomy has been used to guide the analysis of this review.

CONCLUSIONS

Although social media features are commonly included in DBCIs, there is an acute lack of information with respect to their effect on outcomes and a lack of clear guidance to inform the selection process based on the features’ suitability for the different behaviors. The proposed taxonomy along with the set of recommendations included in this review will support future research aimed at isolating and reporting the effects of social media features on DBCIs, cross-study comparisons, and evaluations.
Uterine Artery Embolization Versus Hysterectomy in the Treatment of Symptomatic Adenomyosis: Protocol for the Randomized QUESTA Trial (Preprint)
Authors: de Bruijn Annefleur Machteld , Lohle Paul NM , Huirne Judith AF , de Vries Jolanda , Twisk Moniek ,   QUESTA-Trial Group, Hehenkamp Wouter JK
Published: March 2018

BACKGROUND

Adenomyosis is a benign uterine disease characterized by invasion of endometrium into the myometrium resulting in heavy menstrual bleeding and pain (dysmenorrhea). Hysterectomy is established as the final treatment option when conservative treatment fails. Uterine artery embolization (UAE) in patients with symptomatic adenomyosis has demonstrated to reduce symptoms and improve quality of life. However, randomized controlled trials are lacking.

OBJECTIVE

With this study, we aim to evaluate the impact of UAE on Health-Related Quality of Life (HRQOL) in a randomized comparison to hysterectomy in patients with symptomatic adenomyosis.

METHODS

This is a multicenter non-blinded randomized controlled trial comparing UAE and hysterectomy. Eligible patients are symptomatic premenopausal women without the desire to conceive and who have symptomatic magnetic resonance imaging (MRI)–confirmed pure adenomyosis or dominant adenomyosis accompanied by fibroids. After obtaining informed consent, patients will be randomly allocated to treatment in a 2:1 UAE versus hysterectomy ratio. The primary objective is HRQOL at 6 months following the assigned intervention. Secondary outcomes are technical results, pain management, clinical outcomes, HRQOL, and cost effectiveness during 2 years of follow-up. In addition, transvaginal ultrasound (TVUS) and MRI will be performed at regular intervals after UAE.

RESULTS

Patient enrollment started November 2015. The follow-up period will be completed two years after inclusion of the last patient. At the time of submission of this article, data cleaning and analyses have not yet started.

CONCLUSIONS

This trial will provide insight for caretakers and future patients about the effect of UAE compared to the gold standard hysterectomy in the treatment of symptomatic adenomyosis and is therefore expected to improve patients’ wellbeing and quality of life.

Authors: Broadbent Elizabeth , Garrett Jeff , Jepsen Nicola , Li Ogilvie Vickie , Ahn Ho Seok , Robinson Hayley , Peri Kathryn , Kerse Ngaire , Rouse Paul , Pillai Avinesh , MacDonald Bruce
Published: March 2018

BACKGROUND

Socially assistive robots are being developed for patients to help manage chronic health conditions such as chronic obstructive pulmonary disease (COPD). Adherence to medication and availability of rehabilitation are suboptimal in this patient group, which increases the risk of hospitalization.

OBJECTIVE

This pilot study aimed to investigate the effectiveness of a robot delivering telehealth care to increase adherence to medication and home rehabilitation, improve quality of life, and reduce hospital readmission compared with a standard care control group.

METHODS

At discharge from hospital for a COPD admission, 60 patients were randomized to receive a robot at home for 4 months or to a control group. Number of hospitalization days for respiratory admissions over the 4-month study period was the primary outcome. Medication adherence, frequency of rehabilitation exercise, and quality of life were also assessed. Implementation interviews as well as benefit-cost analysis were conducted.

RESULTS

Intention-to-treat and per protocol analyses showed no significant differences in the number of respiratory-related hospitalizations between groups. The intervention group was more adherent to their long-acting inhalers (mean number of prescribed puffs taken per day=48.5%) than the control group (mean 29.5%, P=.03, d=0.68) assessed via electronic recording. Self-reported adherence was also higher in the intervention group after controlling for covariates (P=.04). The intervention group increased their rehabilitation exercise frequency compared with the control group (mean difference −4.53, 95% CI −7.16 to −1.92). There were no significant differences in quality of life. Of the 25 patients who had the robot, 19 had favorable attitudes.

CONCLUSIONS

This pilot study suggests that a homecare robot can improve adherence to medication and increase exercise. Further research is needed with a larger sample size to further investigate effects on hospitalizations after improvements are made to the robots. The robots could be especially useful for patients struggling with adherence.

Effect of Impulsive Compression Treatment on Postoperative Complications After Open Peripheral Vascular Revascularization (In Situ): Protocol for a Randomized Control Trial (Preprint)
Authors: Klit Tenna , Dahl Marie , Houlind Kim Christian , Ravn Hans
Published: March 2018

BACKGROUND

In patients with critical leg ischemia (CLI), the standard operative choice is an in situ bypass to the lower extremity to improve the patients´ prognosis and quality of life. Postoperative complications after surgery occur in 18 % of the patients, prolonging hospitalization and convalescence. The main operative complication is edema. This can be prevented by early mobilization or stimulation of the natural venous pump in the leg.

OBJECTIVE

To investigate whether compression therapy with foot pump reduces postoperative edema, facilitates wound healing of the operation wounds, promotes healing of ischemic ulcers, and shortens hospitalization, increasing and improving the patient’s subjective quality of life faster.

METHODS

The protocol is designed as a randomized, unblinded prospective study with 50 patients in each group. Standard postoperative routines after bypass surgery, including short-stretch bandaging of the operated legs, are compared to supportive stimulation of the venous pump by an impulsive compression foot pump. The postoperative edema of the leg is measured 10 cm below the patella and 8 cm proximal to the medial malleolus. Measurements are performed preoperatively, 1 and 4 days postoperatively and at discharge.

RESULTS

The primary endpoint is reduction of leg edema by at least 50%. The secondary endpoint includes earlier mobilization in the pump group and decreased length of stay in hospital. Quality of life is evaluated through the European Health Related Quality of Life Questionnaire 5 Dimensions (EQ-5D) and Vascular Quality of Life Questionnaire-6 (VascuQol-6) questionnaires. The start of the study is February 1, 2018, and the end of the study is February 1, 2020. First results will be available April 2020.

CONCLUSIONS

In orthopedic surgery of the lower extremities, the use of foot pumps has shown a reduction of edema and thrombosis in risk patients. Although important positive effects may be expected after vein bypass surgery, no reports have yet investigated the use of the device in vascular-operated patients and no analysis or meta Cochrane reviews are available in this field.

Characterizing and Managing Missing Structured Data in Electronic Health Records: Data Analysis (Preprint)
Authors: Beaulieu-Jones Brett K , Lavage Daniel R , Snyder John W , Moore Jason H , Pendergrass Sarah A , Bauer Christopher R
Published: March 2018

BACKGROUND

Missing data is a challenge for all studies; however, this is especially true for electronic health record (EHR)-based analyses. Failure to appropriately consider missing data can lead to biased results. While there has been extensive theoretical work on imputation, and many sophisticated methods are now available, it remains quite challenging for researchers to implement these methods appropriately. Here, we provide detailed procedures for when and how to conduct imputation of EHR laboratory results.

OBJECTIVE

The objective of this study was to demonstrate how the mechanism of missingness can be assessed, evaluate the performance of a variety of imputation methods, and describe some of the most frequent problems that can be encountered.

METHODS

We analyzed clinical laboratory measures from 602,366 patients in the EHR of Geisinger Health System in Pennsylvania, USA. Using these data, we constructed a representative set of complete cases and assessed the performance of 12 different imputation methods for missing data that was simulated based on 4 mechanisms of missingness (missing completely at random, missing not at random, missing at random, and real data modelling).

RESULTS

Our results showed that several methods, including variations of Multivariate Imputation by Chained Equations (MICE) and softImpute, consistently imputed missing values with low error; however, only a subset of the MICE methods was suitable for multiple imputation.

CONCLUSIONS

The analyses we describe provide an outline of considerations for dealing with missing EHR data, steps that researchers can perform to characterize missingness within their own data, and an evaluation of methods that can be applied to impute clinical data. While the performance of methods may vary between datasets, the process we describe can be generalized to the majority of structured data types that exist in EHRs, and all of our methods and code are publicly available.
Supporting Our Valued Adolescents (SOVA), a Social Media Website for Adolescents with Depression and/or Anxiety: Technological Feasibility, Usability, and Acceptability Study (Preprint)

BACKGROUND

Supporting Our Valued Adolescents (SOVA), a social media website for adolescents, was designed to increase mental health literacy and address negative health beliefs toward depression and/or anxiety diagnosis and treatment. This stakeholder-informed site underwent iterative user testing to evolve into its current version with daily blog posts, round-the-clock site moderation, and Web-based peer interaction to create an online support community.

OBJECTIVE

The aim of this study was to evaluate the technological feasibility (at least 100 users on the site, logging in 12 to 18 times in the first 6 weeks) and acceptability of the SOVA site determined by the System Usability Scale (SUS).

METHODS

Adolescents and young adults (aged 14-26 years) with a self-reported history of depressive and/or anxiety symptoms were recruited to access the research website (sova.pitt.edu). Participants were screened out if they reported active suicidality or a prior suicide attempt. Baseline survey measures included demographics, symptomatology using the Patient Health Questionnaire-9 modified for adolescents (PHQ-9A) and Screen for Child Anxiety Related Disorders (SCARED-C), and mental health treatment history. The 6-week follow-up measures taken in addition to the symptomatology, included feasibility (total number of log-ins), usability, and acceptability of SOVA using SUS.

RESULTS

Most of the 96 participants identified as female (75% [72/96]) and white (67% [64/96]). Most participants (73% [70/96]) reported having taken prior professional psychological help. The average PHQ-9A score was 11.8 (SD 5.5), and for SCARED-C, 85% (80/94) of the participants reported a score consistent with being susceptible to a diagnosed anxiety disorder. There were 46% (41/90) of eligible users who ever logged in. Out of the total users who ever logged in, the mean of total log-ins over the entire study was 4.1 (SD 6.9). Median number of users rated the user-friendliness of the site as “good.” The average SUS score was 71.2% (SD 18.7), or a “C-grade,” which correlated to an acceptable range. The participants reported to have liked the “easy-to-understand format” and “positive, helpful atmosphere,” but they also reported a desire for greater social interaction. Iterative recruitment resulted in incremental improvements to the site.

CONCLUSIONS

The SOVA site met feasibility goals of recruiting almost 100 users and establishing acceptable usability. Subsequent interventions are planned to increase site engagement and to evaluate efficacy in increasing uptake of primary care–recommended depression and/or anxiety treatment.
CHARACTERIZATION OF GENE KETOACYL-ACP SYNTHASE II (KAS II) β ON Elaeis guineensis, Elaeis oleifera, AND INTERSPECIFIC HYBRID
Authors: Siregar Heri Adriwan , Wening Sri , Purba Abdul Razak
Published: March 2018

Oil palm (Elaeis guineensis) is currently the highest edible oil-producing plant in the world. E. oleifera is another species of oil palm that is not widely cultivated due to lower productivity. Oil extracted from E. guineensis has a balance ratio of saturated to unsaturated fatty acids level, while E. oleifera has a higher unsaturated fatty acids. Long chain saturated fatty acids are more harmful for human health than unsaturated fatty acids. Gene encoding β-ketoacyl ACP synthase II (KAS II, EC 2.3.1.179) was studied, as this enzyme is responsible for biosynthesis of unsaturated fatty acids. Observation and analysis were conducted for KAS II gene and fatty acids content of E. guineensis represented by DxP Lame, DxP Langkat and CMR78 samples, E. oleifera represented by Suriname origin, and two hybrids (E. guineensis x E. oleifera (Brazil and Suriname)). The results showed E. oleifera Suriname had the highest concentration of oleic acid, followed by E. guineensis (CMR78). KAS II gene sequences alignment showed some genetic variation within E. guineensis and hybrids, while the high level of variation found between E. guineensis and E. oleifera was considered caused by species difference.

A atuação de Silas Malafaia contra o PLC 122: análise de suas páginas no Twitter e no Facebook
Authors: Feliciani Márcia Zanin , Schirmer Leandra Cohen , Dalmolin Aline Roes
Published: March 2018

O PLC 122/2006 foi uma proposta de lei criada pela deputada Iara Bernardi com o objetivo de criminalizar atos de violência física e/ou simbólica referentes a sexualidade e gênero. Grupos conservadores posicionaram-se fortemente em contrariedade à aprovação do projeto, alegando que o mesmo feria os valores da família, da Constituição (no que tange à liberdade de expressão) e da Bíblia – que, segundo determinadas leituras, consideraria a homossexualidade pecaminosa. Percebemos Silas Malafaia, líder da Igreja Assembleia de Deus Vitória em Cristo, como uma das personalidades mais atuantes nesse processo; assim, a partir dos conceitos de empreendedorismo moral (BECKER, 2008), campo social e, mais especificamente, campo religioso (BOURDIEU, 1983; 2008), midiatização e circulação (BRAGA, 2012), buscaremos compreender a atuação do pastor com relação aos desdobramentos que se seguiram à proposta. Ter-se-á como objeto as postagens feitas em seus perfis no Twitter e no Facebook nos anos de 2011 e 2012 – período em que as discussões sobre o PLC intensificaram-se.
Serbian еcclesiastical chanting for the glory of god and in the service of the nation
Authors: Peno Vesna , Vesic Ivana
Published: March 2018

Shaped in complex social circumstances and in accordance with the postulates
of baroque historicism, Serbian ecclesial art has expressed clear tendency
toward nationalization of Serbian religious identity during the 18th century.
Due to general musical illiteracy of the clerics, the real conditions for the
development of chanting art in Serbian Church were nonexistent. However, by
the end of 18th and at the beginning of the 19th century the myth of
authentic Serbian national Church singing, being the result of special
?Serbian folk piety?, was established. The construction of Serbian Church
chanting tradition was primarily initialized by the growing distance from
Greek psalmody in Serbian worship. In other words, because there was no
historically relevant form of singing, the ancient singing of Fruska Gora and
Krusedol, i.e. the singing of Karlovci, had to be constructed as an
antithesis to Byzantine- Greek musical tradition. By comparing historical
facts and critically reading the narrative of the origins of national Church
music in the time of Metropolitan Stefan Stratimirovic of Karlovci, a new
interpretation of common stereotype about Serbian musical reform and its main
protagonists was produced. This paper offers an original analysis of the
origin of: 1) the singing of Fruska Gora, in the context of the belief that
Fruska Gora, with its monasteries which preserved the memory of the golden
age of Serbian history, are sacred spaces - Serbian Mount Athos; as well as
2) the singing of Karlovci, where was the centre of Metropolitanate of
Karlovci and first Ecclesiastical Seminary which was connected the ungrounded
belief that it was nursery of a magnificent form of church chanting by the
end of the 18th and the beginning of the 19th century. This paper, also for
the first time, pointed the relationship between the monasteries of Fruska
Gora, as Serbian sacred spaces of great importance for national identity, and
their abbots Dimitrije Krestic, Dionisije Cupic and Jerotej Mutibaric, who
were, according to oral tradition, the creators of singing of Karlovci. The
adequate music and historical sources that would offer us an insight into the
process of musical reform that was conducted by them do not exist, but their
contributions in constituting national self-awareness and ?Serbian piety? are
well known and documented. In conclusion, by the end of the 18th and the
beginning of 19th century, but also during the entire century of
?nationalism(s)?, the prayers in Serbian Church were chanted for the glory
of God, although with a clear tendency to emancipate a new religious identity
of Serbian people. However, the catholic ecclesial spirit of Tradition was
repressed in order to fulfill the goals of ideology of religious nationalism.
