ABSTRACT             The identification of the community's readiness to develop their capability from farming to culinary to support food security needs understanding and awareness about personal hygiene. Observations, interviews, and questionnaires were used to determine 100 respondents from 8 sub villages in Banyusoco, Playen, Gunungkidul. The level of knowledge, understanding, and awareness of self-hygiene is explored from the implementation of socialization, the impact of dissemination and training activities, the frequency of hand washing before handling food, the frequency of handwashing with soap or disinfectant after using the toilet, at the dining area, and time for at least 20 seconds use of soap. Readiness analysis is also reviewed from the level of education. The results of identification show that daily habits that affect consciousness are needed. However, further research and dissemination are needed to explain the differences between behavioral reports, abilities, and awareness.Keywords: dissemination, practice, knowledge, consciousness, personal hygiene
Uang dan Peluang: Konsumsi Barang Virtual dalam Game RF Online Indonesia
Authors: Priatama Ardhano
Published: April 2019

Studi mengenai permainan daring merupakan fenomena yang menarik karena para pemain terlibat dalam aktivitas budaya ekonomi yang praktiknya belum cukup banyak dikenali atau tidak biasa. Salah satu contoh ditunjukkan melalui transaksi jual beli barang virtual yang melibatkan pertukaran barang dan uang yang dilakukan oleh para pemain. RF Online merupakan salah satu permainan daring di Indonesia yang melibatkan transaksi uang dengan suku bunga yang tinggi melalui pertukaran barang virtual. Barang virtual adalah kumpulan data komputer yang dianggap setara dengan nilai uang yang konkrit. Kajian ini menunjukkan bahwa kekayaan yang bersifat non fisik (intangible) mempengaruhi banyak orang untuk terus mengkonsumsi permainan daring. Kesediaan para pemain untuk membeli barang-barang virtual mengindikasikan bahwa ada “keuntungan” yang ada dibalik perilaku mengkonsumsi permainan daring tersebut. Penelitian ini dilakukan untuk menjawab bagaimana konsumsi barang-barang virtual memberikan keuntungan pada para pemain RF Online. Metode virtual etnografi yang dilakukan dalam studi ini menunjukkan bahwa keuntungan-keuntungan dari konsumsi barang-barang virtual dalam permainan daring diobyektifikasikan melalui kapital budaya. Kapital budaya ini hanya dapat diperoleh dengan memperluas akses jejaring sosial yang menghasilkan cara-cara memperoleh keuntungan ekonomi.

Capitalismo conducido por las finanzas y financiarización de la industria farmacéutica de Estados Unidos
Authors: Baranes Avraham Izhar
Published: April 2019

El análisis de las etapas del capitalismo de Minsky ofrece un conjunto analítico útil para entender no solo la transformación de la economía estadounidense, sino también de la empresa de negocios. Usando el concepto de empresa de negocios de la microeconómica heterodoxa, este artículo examina su evolución, enfocado en cómo la empresa se financiariza, bajo el capitalismo conducido por las finanzas (CCF). Es importante el creciente papel que los activos intangibles han tenido en generar ganancias para los accionistas. Esto se ve claramente en la industria farmaceútica estadounidense, en donde se ha visto que tienen un papel creciente en el balance los activos intangibles. Aunque muchas investigaciones han enfatizado la desigualdad económica, la inestabilidad y los altos precios de las medicinas, es importante conocer el papel que la financiarización de la economía ha tenido para generar estos problemas.

 
Ciclo largo y sistema financiero: Crisis, contracción del crédito y ganancia
Authors: Aguirre Teresa
Published: April 2019

Los ciclos económicos y el sistema financiero se relacionan de diferentes maneras, una de las más destacas que han analizado la relación entre el ciclo económico y finanzas, ha sido el estudio de las ondas largas o ciclos Kondratieff. Otra forma de análisis ha sido a través del ciclo monetario que conduce a las crisis financieras (Minsky y Kindleberger entre los más conocidos) y finalmente una manera distinta ha sido el estudio de las particularidades de cada ciclo de auge-frenesí financiero y declive. Este trabajo propone un breve recuento de cómo se ha analizado la relación: capital productivo y financiero en las ondas largas, a través del planteamiento de tres de tres autores que han marcado hitos en el análisis: Nikolai Kondratieff, Ernest Mandel y Carlota Pérez. Nuestro objetivo es indagar sobre una pregunta central que se hace de manera reiterada: ¿por qué a pesar de la revolución científico-técnica basada en la informática, con el desarrollo de la robótica, cibernética, biotecnología y nanotecnología, no se ha logrado una etapa de crecimiento sólida y sostenida que dé lugar a una etapa expansiva.

 
La necesidad de una nueva administración pública
Authors: Galbraith James K.
Published: April 2019

 

El modelo económico de acuerdo con el cual los mercados se equilibran por si mismos descansa sobre una visión del mundo de harmonía y estasis que retorna a la China clásica, y ha sido completamente rechazado en todos los campos de la ciencia y también en la economía política en el siglo XIX. De alguna manera sobrevive en los libros de texto de economía hasta el día de hoy. Una nueva administración pública necesita apoyarse en los hábitos científicos modernos, reconociendo que todos los sistemas biológicos, mecánicos y sociales requieren de una regulación efectiva, no para “reducir externalidades” sino porque de otra manera no puede existir en absoluto. Una vez que se reconoce esto, la tarea del gobierno es hacer que funcionen bien la regulación y la provisión pública de servicios, minimizando la depredación, el parasitismo, la fuerza y el fraude.  

 
La hipótesis de la inestabilidad financiera: una propuesta de desarrollo
Authors: Delgado Selley Orlando
Published: April 2019

En este trabajo se hace una revisión de las contribuciones de Minsky para la construcción de una teoría que, siguiendo los planteamientos de Keynes, permite explicar la tendencia de las economías modernas a la inestabilidad. En seguida se incorpora una propuesta de desarrollo a la hipótesis de la inestabilidad financiera (HIF) hecha por A. Vercelli, que permite añadir a los tres tipos de unidades económicas consideradas por Minsky otros tres tipos de unidades económicas, entre las que aparecen los hogares, lo que amplía las posibilidades analíticas de la HIF para explicar el funcionamiento de la economía y, particularmente, el episodio crítico de 2007.

The posterior thalamoperforating artery (the main perforating trunk from P1) microsurgical study
Authors: Neto Aziz Rassi , Antunes Ápio Cláudio Martins , Braga Fernando Menezes
Published: April 2019

Thirty fresh human brains were studied regarding to the anatomy of the posterior thalamoperforating arteries (PThPA): origin, number, diameter, traject, distance from the basilar artery bifurcation, type of distribution and correspondent area of vascularization. Most of the PThPAs originated proximally in the posterior cerebral artery (PCA), irrigating the cerebral, peduncles, mammilary bodies, ventral portion of midbrain and, through the posterior perforated substance, the medial portion of thalamus. The mean number of PThPAs per hemisphere was 1.51, mean proximal diameter 0.60 mm and mean distance from PCA origin 2.47 mm. A deep knowledge of the microsurgical anatomy of PThPAs is stressed, as devastating lesions can develop after arterial compromise during neurosurgical procedures.
The development of scientific outlook of students when teaching inverse problems for differential equations
Authors: Kornilov Viktor Semenovich
Published: April 2019

Problem and goal. Modern achievements of the world Science of nature and the world, physical laws and laws should be disclosed at an accessible level to University students. Among the scientific methods of research of physical processes and phenomena, an important place is the method of mathematical modeling, because mathematical models have scientific and cognitive potential and versatility (see, for example, [2-4]). The use of mathematical models of inverse problems for differential equations (IPDE) allows to effectively investigate many processes and phenomena occurring in the air, earth and water environment. It is not surprising that in some Russian universities in the physical and mathematical areas of training are taught IPDE in the form of a choice of courses. The goals and objectives of such teaching are set, as a result of which students would develop creative mathematical abilities, formed fundamental knowledge in the field of physical education, developed a scientific worldview. Methodology. The development of scientific outlook of students of physical and mathematical directions of preparation, as a result of teaching IPDE, ensured the successful will be implemented in practice, such conditions as: 1. the involvement of experts in the field IPDE with teaching experience at the university; 2. development of the content of lectures and practical classes on the basis of modern achievements of the theory of inverse and incorrect problems, taking into account the professional orientation of training students; 3. the implementation of the principles, methods and means of education IPDE; 4. involvement of students in research work in scientific seminars and participation in scientific conferences devoted to IPDE; 5. implementation of methodological approaches that allow students to develop the skills and abilities of independent analysis of applied and humanitarian nature of the results of research of IPDE. Results. In practical classes on the IPDE students acquire the ability and skills to apply effective approaches and mathematical methods of finding solutions to inverse problems, followed by a logical analysis of their solutions. As a result, students gain useful experience in the analysis of new information about the studied physical processes and phenomena, form new scientific knowledge about the world on the basis of which develop a scientific worldview. Conclusion. Developed, in the process of teaching IPDE, the scientific outlook helps students to understand that mathematical models IPDE are relevant to theory, experiment and philosophy - the basic methods of knowledge researchers; to understand the humanitarian value of mathematical models IPDE.
Japanese Universities’ Community in International Environment: Maneuvers or Heading Down?
Authors: Zhilina Larisa Vladimirovna
Published: April 2019

The article discusses the issues that striving for getting on the first lines of ratings, Japanese universities have faced to face with in recent years. Since 2003, when universities began to receive their public evaluation on the pages of global university ratings, the world university system has entered a new phase of its development. For many countries, including Japan, getting into the top-list of global ratings has become almost a national goal. Of the new issues that have emerged over the course of the past years, the most important at present is the “internationalization” of Japanese universities and the most obvious manifestations of this tendency are the increasing interest in world university rankings. At the same time in Japan internationalization has become both a universities and a government priority because it is seen as a sign of global competitiveness. Since 2000, the government has introduced a series of legislative and policy initiatives aimed at increasing institutional autonomy and management capabilities, enhancing evaluation and emphasizing quality, and developing internationally-competitive research via centres of excellence and graduate schools. To solve this problem the Japanese government decided to increase the number of international students from the current 100,000 to 300,000 by 2020. However now the ranking of Japanese universities is on a downward trajectory, as universities elsewhere in East Asia catch up. In order to become more competitive with universities in other countries, Japan needs to open up its universities and work positively to welcome more-and more talented-researchers and students from overseas, it also needs to increase the number of courses available in English. At the same time it needs to send more Japanese researchers and students overseas to stimulate their research and improve necessary for top-ranking standards.

Published: April 2019

The article discusses the differences in attitudes towards dental health among persons with and without medical education. The authors described the criteria for assessing the quality of dental care, the preferred quality of a dentist and causes dental phobia in the adult population, as well as highlighted ways to improve compliance and reduce fear and anxiety before visiting the dentist. A total of 88 apparently healthy respondents who do not pass dental treatment at the time of the study (52 women and 36 men) took part in the study (the average age is 32 ± 12.5 years). The following techniques were used: (1) the survey Attitude to Health by R.A. Berezovskaya for assessing the respondents’ attitude to their own health (emotional, behavioral, cognitive, and valuemotivational scales); (2) the Life Quality Scale by N.E. Vodopianova for the assessment of the general life quality index and the self-assessment of the respondents life quality in such categories as: work, personal achievements, health, communication with relatives, support, optimism, tension, self-control, negative emotions; (3) the questionnaire Attitude to dental health developed for research at the Department of General and Clinical Psychology of Pavlov First Saint Petersburg State Medical University. Key research findings is: (1) most patients prefer an empathic-non-prescriptive type of dentist; (2) for most patients are important professional and communication skills of the dentist; (3) there are differences in attitudes towards dental health in patients with and without medical education.

Published: April 2019

Recently, wehave discussed the warped product pseudo-slant submanifolds of
the typeM?xfM? of Kenmotsu manifolds. In this paper, we study other type of
warped product pseudo-slant submanifolds by reversing these two factors in
Kenmotsu manifolds. The existence of such warped product immersions is
proved by a characterization. Also, we provide an example of warped product
pseudo-slant submanifolds. Finally, we establish a sharp estimation such as
||h||2?2pcos2?(||??(ln f)||2-1) for the squared norm of the second
fundamental form khk2, in terms of the warping function f, where ??(ln f)
is the gradient vector of the function ln f. The equality case is also
discussed.

In the present paper, we introduce a generalization of Bal?zs-Szabados
operators by means of (p,q)-calculus. We give the rate of convergence of
Bal?zs-Szabados operators on based (p,q)-integrers by using Lipschitz
class function and the Peetre?s K-functional. We give the degree of
asymptotic approximation by means of Voronoskaja type theorem. Further, we
give some comparisons associated the convergence of Bal?zs-Szabados, q-Bal?zs-Szabados and (p,q)-Bal?zs-Szabados operators to certain functions
by illustrations. Moreover, we investigate the properties of the weighted
approximation for these operators.

Journalistinen uutissatiiri hybridinä genrenä - Noin viikon uutisten ja Uutisraportin tekijöiden itseymmärrys ja käsitteellinen rajatyö
Authors: Koivukoski Joonas
Published: April 2019

Tarkastelen tässä artikkelissa journalistisen uutissatiirin työkäytäntöjä ja merkityksiä genren ja rajatyön käsitteiden kautta. Aineistona on kahdeksan teemahaastattelua, joita erittelen laadullisen sisällönanalyysin avulla. Analysoin erityisesti ohjelmien pääosiota ja tekijöiden käsitteellisiä erotteluja suhteessa aiempaan satiiriin ja perinteiseen uutisjournalismiin. Väitän, että ohjelmien pääosio on journalistisen uutissatiirigenren varsinainen innovaatio, jossa yhdistyvät sekä toimittajien että stand up -koomikoiden ammattitaidot. Osiossa faktuaalinen taustoittaminen ja temaattinen kehystäminen sekoittuvat ajankohtaisten asioiden karnevalisointiin ja ironisointiin. Tekijät erottavat tämän vuoksi ohjelmansa aiemmasta pinnallisesta ajankohtaissatiirista ja neutraalimmasta uutisjournalismista. Tutkimuksen valossa näyttää siltä, että ammatillinen eetos siirtyy toimittajien mukana viihteen tekemiseen. Näin myös viihde muuttuu journalistisemmaksi, eikä vain toisinpäin kuten on usein pessimistisesti esitetty. Uusi hybridi uutissatiiri haastaa perinteistä vastakkainasettelua kovien ja viihteellisten journalististen genrejen välillä.
Gendered Nationalism, Neo-Nomadism, and Ethnic-Based Exclusivity in Kyrgyz, Kazakh and Uzbek Nationalist Discourses
Authors: Belafatti Fabio
Published: April 2019

Existing literature on gender and nationalism has postulated that nationalist narratives tend to convey patriarchal and restrictive views of gender roles, with women’s domesticity and subordination at the core of such interpretations. This paper tests this theory by looking at three examples of state-sponsored or state-produced communication in Kazakhstan, Kyrgyzstan and Uzbekistan, arguing that the simple existence of a regime’s nationalist ideological orientation is not per se sufficient to explain or anticipate the kind of gender narratives a regime will adopt. Instead, the paper calls for an analysis of internal political mechanisms and incentives in order to explain and anticipate the specific forms that discourses around gender will take in a given political environment. In order to do so, it tries to combine the rational choice-based “Selectorate Theory” (Bueno de Mesquita et al., 2003) with existing literature on nationalism and gender, to define a connection between political systems on the one hand and discourses on the other.

Authors: Choi YoungJu , Tak Jinkook
Published: April 2019

The purpose of this study was to examine the relationships among authentic leadership, job engagement, and procedural justice. Specifically, this study investigated the influence of authentic leadership on procedural justice and job engagement that was partially mediated by procedural justice. In addition, this study examined moderating effect of positive psychological capital on the relationship between authentic leadership and procedural justice and the effect of power distance on the relationship between procedural justice and job engagement. Data were collected from 300 Korean employees who were working in various organization via online survey, and 286 data were used for analysis, eliminating unreliable responses. The findings are as follows: First, there were positive relationships among authentic leadership, job engagement, and procedural justice. Second, the results of structural equaition analysis showed strong support for the proposed model, and the result of bootstrapping analysis supported that the effect of authentic leadership on job engagement is partially mediated by the procedural justice. Third, the results of hierarchial analysis showed that positive psychological capital moderated the relationship between authentic leadership and procedural justice, but there was no moderating effect of power distance on the relationship between procedural justice and job engagement. Finally, implications and limitations of this study with the direction for future research were discussed on the basis of the results.

Authors: Kang SunA , Park ChoonShin , Chang JaeYoon
Published: April 2019

The present study aimed to replicate Bennett et al. (2016)’s study that investigated the profiles of recovery experiences among U.S. employees. A sample of 472 Korean employees was surveyed on their four recovery experiences(psychological detachment, relaxation, mastery and control; Sonnentag & Fritz, 2007) and problem-solving pondering during typical leisure time. By adopting person-centered approach using the latent profile analysis, we identified three profiles of recovery experiences: Recovery, Intermediate, and Fatigue Profiles. There were significant differences among these three profiles in demographics(age, marriage status, and the number of children) and job conditions(job demands, job resources), and well-being outcomes(work engagement, emotional exhaustion, sleep quality). By comparing the results with those of Bennett et al. (2016), we discussed the implications and limitations of this study, and suggested directions for the future studies.
Influences of power distance and uncertainty avoidance on innovative work behavior
Authors: Kim Jungsik , Fan Zhou
Published: April 2019

This study examines the relationships between employees’ cultural value orientations and their innovative work behaviors and the mediation effects of self-leadership in the relationships. Four hundred and eighty two employees working at various firms in Korea and China responded to a questionnaire consisting of measures designed to assess uncertainty avoidance, power distance, and innovative work behavior. Analyses of the data revealed that power distance was negatively related to innovative work behavior for both respondents while uncertainty avoidance was positively related to innovative work behavior. The mediation effects of self-leadership were also found. This study contributes to current research literature by providing empirical evidence for the role of self-leadership in the mechanism linking individuals’ cultural value orientations and innovative work behavior. The study also discusses similarities and differences in the patterns of power distance, uncertainty avoidance, innovative work behavior, and self-leadership across Korean and Chinese respondents and their implications in changing business environment.
The buffering effects of trait resilience on The damaging effects of conflict on residual emotion
Authors: Oh Sunyoung , Suh Yongwon
Published: April 2019

The purpose of the present research was to examine the possibility that trait resilience can serve adaptive functions in regulating the effects of relationship damaging effects of relationship conflict stress. Specifically, the present research suggested that trait resilience facilitates the experience of positive emotion, which weakens the relationship between conflict stress and residual emotions for the other party in conflict situations. A 14-day diary study was conducted to collect relationship conflict in daily life. The results of analysis of 297 conflict events showed that trait resilience affected the level of positive emotion experienced after conflict occurrence, which significantly moderated the strength of indirect effects of conflict stress on residual emotions. These findings indicate that trait resilience can serve as a protective factor against the relationship damaging effects of relationship conflicts. The discussion focuses on implications of the findings in terms of organizational adjustment and organizational effectiveness, limitations and suggestions for future research.

Authors: Aqeel Sara , A. Sidky Rehab
Published: April 2019

Plant tissue responds to nutrient media due to the plant cultivars genetic diversity. The objective of this research is to determine the effects of micronutrients on date palm growth and which of these micronutrients are critical for improving growth combined with Paclobutrazol or without on in vitro of elongation stage. In vitro growth of two cultivars were determined by varying five treatments that included minor salts (EDTA-chelated iron, CuSo4,) alone or combined with Paclobutrazol. The effects of these five treatments on plantlet length, trunk thickness, rooting number and Chlorophyll A, B was investigated. The results obtained after three months showed that, increasing copper sulphate on MS elongation media combined with Paclobutrazol was more effective for increasing the trunk thickness as well as rooting number compared with normal MS level. While poor response was found when Fe was increased in the chelated form of Fe-EDTA on MS elongation media.  For cultivars, Shishi gave the highest plantlets length as well as root number. The maximum content of chlorophylls A and B were observed when copper sulphate was increased on MS elongation media with cultivar Lulu. The survival rate after 3 months was related to the medium used during the elongation phase, the survival of plantlets reached to 98.66% with cultivar lulu at the acclimatization stage.

Various health challenges and fatalities in rural communities of most developing countries of the world have been traceable to the unabated use of biomass energy sources. We therefore assessed the awareness of the health implications of the use of biomass energy sources among women in rural households of Jigawa State. Multistage sampling procedure was used to collect data from 120 respondents using structured questionnaires. Data were collected on respondents’ socioeconomic characteristics, types of biomass used, information sources on the health implications from use of biomass energy sources, awareness of the health implications and constraints to the use of alternatives to biomass. Data were summarised using frequencies, percentages, means, Chi-square and Pearson Product Moment Correlation. Majority of the respondents (78.3 %) were below 40 years of age with a mean age of 30 ± 2.02 years. Majority were married (90.8 %), Muslims (100 %), involved in agro-processing (65.8 %), had no formal education (73.3 %), and earned not more than ₦10, 000 (90.8 %) with mean household size of 9 members. Wood (100 %) and charcoal (100 %) were the dominant biomass energy sources used. Respondents’ main source of information on the health implications of the use of biomass were radio (64.2 %) and extension agents (54.2 %). Awareness level of the health implications from the use of biomass energy sources was fairly high (51.7 %). High cost of the alternatives, scarcity of refilling points and alternatives and lack of capital were the main hindrances to the use of the alternatives to biomass energy sources. The result on the inferential statistics revealed that a significant association existed between education (χ2 = 6.08; P < 0.05) and awareness of health implications from the use of biomass. Efforts should be made to sensitize women on the health implications resulting from the use of biomass. Alternatives should be made available and affordable to encourage a switch from biomass energy sources thereby reducing the fatalities that may result from its continual use.

Numerous prognoses indicate that climate change will manifest itself in extreme climatic conditions. Therefore, it will be of high importance to know in what extent can plant communities and certain species adapt to altering environmental conditions. Our examinations were implemented in stands of sessile oak common in the Carpathian Basin. The reason behind it has been that, according to climatic models, the realized niche of this species can be reduced by 80% in some regions by 2050. Examinations were made in 3 points of an approximately 400 km long (East-West) transsect crossing the Carpathian Basin: 3 submontane regions of a subatlantic, a continental and a subcarpathian mountain were involved with 5 age groups in each regions. Health status examinations of sessile oaks have been completed by using FAKOPP 3D acoustic tomograph. Among the three venues trees of the subatlantic area were the healthiest; here, the 100 years old age group showed the lowest deterioration, only 0.68%. The most severely deteriorated stands occur in the continental region where the value in the 60 years old age group reached 4.24%. It seems that, besides annual precipitation, the method of planting also influences the health status of stands, since considerable differences could be observed between coppice and seedling stands.

Introduction The aim of this study was to compare compressive strength (Cs) of new nanostructural calcium silicate based cement (nCS) with commercial calcium silicate cement and conventional GIC. Methods Four nanostructural materials were tested: nanostructural calcium silicate based cement (nCS) (Jokanović et al.), MTA Plus (Cerkamed, Poland), Fuji IX (GC Corporation, Japan) and Ketac Universal Aplicap (3M ESPE, USA). Five samples of each material were mixed in accordance with manifecturer’s guidelines and positioned in metal moulds (ϕ4mm and 6mm). Compressive strength (Cs) expressed in MPa was determined after 24 hours, 7 days and 28 days respectively. Measurements were performed on universal testing equipment (Tinius Olsen, USA) at a crosshead speed of 1mm/min. For processing the results one-way ANOVA and post-hoc test were used. Results The highest values of compressive strength after 24h was found in conventional GIC Fuji IX (mean 38.56±13.31) and Ketac Universal (mean 40.77±7.96). Calcium silicate cements after 24h showed low values of compressive strength (MTA Plus 5.91±0.28 MPa, nCS 1.35±0.36 MPa). After 7 days, FUJI IX 47.42±9.33 MPa and Ketac Universal 35.25±10.60 MPa showed higher value of compressive strength than MTA Plus (15.09±2.77 MPa) and nCS (11.06±0.88 MPa). After 28 days the Cs value for conventional GIC Fuji IX was 48.03±7.82 MPa and Ketac Universal 36.65±11.13 MPa while for calcium silicate cements it was 16.47±1.89 MPa and nCS 14.39±1.63 MPa. There was statistically significant difference (p<0.05) in Cs between conventional GIC and CS cements after 24h, 7 and 28 days. Conclusions Calcium silicate cements initially showed lower values of compressive strength than conventional GIC that increased over time.

Stem cells have shown great potential for in vitro tissue engineering, regenerative medicine, cell therapy and pharmaceutical applications. All these applications, especially in clinical trials, will require guided production of high-quality cells. Traditional culture techniques and applications have been performed for the majority of primary and established cell lines and standardized for various analyses. Still, these culture conditions are unable to mimic dynamic and specialized three-dimensional microenvironment of the stem cells’ niche from in vivo conditions. In an attempt to provide biomimetic microenvironments for stem cells in vitro growth, three-dimensional culture techniques have been developed. In our study advantages of newly developed porous scaffolds as the most promising in vitro imitation of niche that provides physical support, enables cell growth, regeneration and neovascularization, while they are replaced in time with newly created tissue was explained. Furthermore, dynamic cultivation techniques have been described, as new way of cell culturing that will be the main subject of our future research. In that manner, by developing an optimal dynamic culturing method, high-quality new cells and tissues would be possible to obtain, for any future clinical application.

Introduction Prognosis of endodontically treated tooth is directly correlated to the quality of apical obturation. Modern concept of endodontics in particular way points out the quality of apical filling. The aim of this study was to assess the quality of root canal obturation with MTA apical plug using the method of gas (argon) penetration.

Material and Methods Sixty-six freshly extracted single rooted (single canal) teeth were divided into the two experimental (30 teeth) and one control group (6). All canals were instrumented using hand and rotary files in step-back technique and copious irrigation of 1%NaOCl. In the first experimental group teeth were obturated using different sealers: Gutta Flow (Roeko), AH Plus (DeTrey), Acroseal (Septodont) and mono gutta-percha cone (10 canals each). In the second experimental group obturation involved 3 mm of MTA-Angelus apical plug while the remaining canal space was filled with the same three sealers as in the first group. The rate of gas permeability by Leak detector-Edwards LD 416 was measured in all teeth.

Results The best seal was found in teeth obturated with Gutta Flow and MTA plug with average diffusion rate of 264.4 sec while the worst quality of obturation was found with Acroseal (178.5 sec-the highest gas permeability). All samples with MTA plug exhibited significantly lower leakage than the samples filled without MTA apical plug.

Conclusion Root canals filled with MTA apical plug exhibited statistically significant lower gas permeability in comparison to the ones filled with sealer and guttapercha cones only.

Introduction Musculoskeletal disorders (MSDs) are one of the most common types of work-related diseases that affect health workers, especially dentists. The aim of our study was to examine the presence of musculoskeletal disorders among dentists at the university dental clinic in correlation with risk factors.

Materials and methods A questionnaire survey was carried out among 78 dental practitioners aged between 20 to 60 years old, employed at the university dental clinic. Questions included data on physical and psychosocial workload, perceived general health and occurrence of musculoskeletal complaints in the past 12 months, chronic complaints, frequency and length of breaks, exercising habits as well as medical care seeking.

Results Pain in the back, neck and shoulders (84.6% / 85.9%) was the most common complaint among the majority of respondents, while reduced range of movement was noticed among significantly fewer subjects, mostly between 40-60 years of age. Prolonged statistic position was considered to be one of the main causes of MSDs (82.05%) while 73.08% of respondents stated at least two more reasons beside this one.

Conclusion The percentage of MSDs prevalence among dentists in public health sector is high. More extensive surveys should be undertaken to cover larger group of dentists from both private and public sector, in order to obtain complete analysis of the prevalence of occupational disorders in our country.
