Cold chain for vaccines a is a system for storing and transporting vaccines at very low temperatures to maintain their effectiveness before use. Because vaccines are sensitive biological substances, their exposition to high temperatures directly affects the quality of vaccines and safety of immunization. The goal of this study was to assess the safety of cold chain for vaccines within the cold chain system in two services of Health Center Novi Sad. Cold Chain Monitors (CCM) and Freeze Watch (FW) indicators were used. A total of 155 (94.5%) Cold Chain Monitors (CCM) and 100 (95.2%) Freeze Watch (FW) indicators were analyzed. Only one CCM showed a breach in cold chain. A total of 3 CCMs indicated risk of vaccine wastage. A total of 9 CCMs were colorized without risk of vaccine wastage, FWs were positive in a high percentage in both services of Health Center Novi Sad. FWs were exposed to low temperatures during transport. Statistically significant differences in the number of exposed CCMs to high temperatures and the number of exposed FWs to low temperatures were observed in these two services. A statistically significant difference in number of FWs exposed to low temperatures was observed in regard to the period of transport and the period of storage at the vaccination stations. The study shows high level of safety of the cold chain in two services of Health Center Novi Sad. Cold Chain Monitor is a reliable indicator of the quality of cold chain for vaccines. Freeze Watch is a reliable indicator of the quality of cold chain during storage of vaccines, but not during their transport.

Myopia Control

Myopia is a global problem affecting all aspects of patients’ lives. Objectives: The aim of the study was to evaluate the influence of low dose atropine (LDA) myopia control on the quality of life in patients with myopia. Material and Methods: A self-constructed questionnaire, including eight questions, was distributed among 40 patients. The questionnaire was divided into two subsections: (1) influence of LDA on visual functions and (2) influence of LDA on self-esteem. Answers were collected separately for boys (18 patients) and girls (22 patients) and compared considering spherical equivalent (SE) and myopia progression rate. Results: Girls reported more issues with near activities and pupil size. Boys and girls complained similarly, regarding the sun glare. We found a high level of certainty about the efficacy of LDA therapy among both examined groups and a little improvement in self-esteem. Girls recommended LDA therapy more often than boys, especially when the progression rate was low. There was no statistically significant difference in answer scores between groups with different myopia progression rates for boys. Girls with lower progression rates reported more issues with near work and sun glare and less trust in LDA therapy’s effectiveness than girls with a higher progression rate. There was no statistically significant correlation between SE and the total answer score for both genders. Conclusions: Findings concerning childrens’ and adolescents’ psyche are a new aspect of myopia control. We prove that patients during pharmacological myopia control did not report significant problems caused by LDA therapy and they were convinced about its efficacy, had greater self-esteem, and recommended it to peers.

sorting because the micro organisms, which help the digestion of high fibre plants, are missing in his stomack, that is why they are mostly called „concentrate selectors” (Hoffmann, 1985, 1988, 1989).These animals should mostly eat easily digestable plants with high nutrition level (pulses, buds, sprouts and flowers), and they are able to do this sorting because of their mouth size. In winter there is a lack of these plants, so the high selectivity occurs only when the feed is in abbundance.Examining the amount and quality of vegetation available on the habitat of roe deer we can identify the species which can satisfy their feed demand. It is known, that roe deer as other large ruminants, from the plant abundance prefer certain plants and plant parts while there are others which are avoided. The identification of the eaten species and the rate of their occurrence in the feed is the first step to become acquainted with the interaction between animal and the surroundings.On the examined territories there was significant difference between the disembowelled body masses. The does which come from the hunt Nagyszénás weighed 4-5 kilos more than the does from the Csongrád territory. The main feed components were present in different rate in the samples of the territories, in the Nagyszénás samples grain, dicotyledonous herbacous plants were dominant, and were eaten more. The high level of grain in the feed result in better condition and larger body mass.

Introduction. Success in functional rehabilitation of the craniomandibular system in patients without teeth, which have total prosthesis, can be assessed using different clinical and functional methods. Subjective assessment, motivation, comfort level and functional efficacy are important elements for adaptation to dental prosthesis as well as base for success in prosthetic therapy. The aim of this study was to evaluate the importance of subjective assessment of the mastication in people with new dental prosthesis as well as to assess the value of that parameter in determining the successful prosthetic therapy. Material and Methods. Study was conducted at the Dental Clinic in Novi Sad. Thirty patients (16 males and 14 females) with average age of 62.5 years who received total prosthesis were included. Analysis was done according to the data from the medical records and conducted survey in the form of questionnaire which was adjusted to our clinical examinations. Results. Results showed that 96.6% of the patients were satisfied with new prosthesis. Subjective assessment of the quality of their mastication before therapy showed that 63.4% consider their mastication as unsatisfied, 26.6% satisfied while 10% of toothless patients thought their mastication was good. Statistic analysis showed there was significant difference in subjective assessment before and after the therapy (p<0.01). In fact, there was significant connection between subjective assessment of the mastication and satisfaction with new prosthesis and therapy at all (p<0.01). Conclusion. Patients satisfaction with total prosthesis and subjective assessment of mastication are in direct correlation with successful prosthetic treatment. Results of subjective assessment of the mastication are important and can be used as a parameter for success along with precise survey.

The usual vigor test of companies for batches of genetic corn seeds is carried out based on the potential of seeds to germinate at low temperatures, not being suitable for the warm regions of the country, since there is a low correlation between laboratory and field results for these cases. An alternative to this method is the GroundEye L800® system, which evaluates vigor by the performance potential of corn seedlings. Thus, the objective was to evaluate the efficiency of the GroundEye L800® equipment in determining the vigor of seeds of the genetic category of corn. Seeds from 36 corn batches were used in this study. The parameters evaluated were germination, radicle emergence test (RET), emergence on flower-bed, besides the image analysis using GroundEye L800® system. RET, the method generally used by companies, showed a significant difference in emergence results compared to those found on flower-bed, with no positive correlation. The GroundEye L800 process and the flower-bed emergence test did not differ statistically. GroundEye L800® equipment is promising for assessing the physiological potential of corn seeds.

ABSTRACT Background The context for specialty residency training in pediatrics has broadened in recent decades to include distributed community sites as well as academic health science centers. Rather than creating parallel, community-only programs, most programs have expanded to include both community and large urban tertiary health center experiences. Despite these changes, there has been relatively little research looking at residents' experiences in these distributed graduate medical education programs. Objective A longitudinal case study was undertaken to explore the experiences of residents in a Canadian pediatrics residency program that involved a combination of clinical placements in a large urban tertiary health center and in regional hospitals. Methods The study drew on 2 streams of primary data: 1-on-1 interviews with residents at the end of each block rotation and annual focus groups with residents. Results A thematic analysis (using grounded theory techniques) of transcripts of the interviews and focus groups identified 6 high-level themes: access to training, quality of learning, patient mix, continuity of care, learner roles, and residents as teachers. Conclusions Rather than finding that certain training contexts were “better” than others when comparing residents' experiences of the various training contexts in this pediatrics residency, what emerged was an understanding that the different settings complemented each other. Residents were adamant that this was not a matter of superiority of one context over any other; their experiences in different contexts each made a valuable contribution to the quality of their training.

The present investigation was aimed to study the level of occupational stress among special education school teachers in relation to their gender. Here, a sample of 120 special education school teachers (60 males and 60 females) was selected from 15 special schools of Delhi, Haryana and Rajasthan states through simple random, purposive, convenience and cluster sampling methods. The survey questionnaire Occupational Stress Index developed and standardised by Dr. A.K. Shrivastava and Dr. A. P. Singh (1981) was used for measuring levels of occupational stress among special education school teachers. Percentage analysis, t-test were employed for data analysis. A higher percentage of special education school teachers were found to be experiencing moderate to high level of occupational stress. The dimensions which causes occupational stress are role conflict and ambiguity, powerlessness, low autonomy, low participation in decision making, little colleague social support, high professional expectations, less security, facilities, nature of job, prestige, intellectual stimulation, advancement and emolument and contingent punishment by the administrator. Besides, perceived level of occupational was also found to be related to gender of special education school teachers. A significant difference in mean OSI scores of male and female special education school teachers (t=2.45 which is significant at 0.05 level of significance) was found. The higher value of mean OSI scores (i.e. 126.54) of male special education school teachers than the value of mean OSI scores (i.e. 116.72) of female special education school teachers indicated that the male special education school teachers perceives high level of occupational stress at their workplace in comparison with the female special education school teachers.Thus, authority of the institutions, state managing body and personnel engaged with the administration of the special education institutions are advised to give due consideration to the above factors while planning about educational management. If the national desire for higher quality of education is to be brought in reality, there must emerge, a national concern for and commitment to a higher quality of the educational environment of the special education school teachers.

Deposited Films

High quality diamond thin films were deposited on different substrates at temperatures from 300 to 1000 °C by the microwave plasma enhanced chemical vapor deposition (MPCVD) system. The quality of deposited diamond films was improved by adding oxygen in the gas mixtures. Different ratios of methane to oxygen concentration in hydrogen at different temperatures have been studied. At high temperatures (800–1000 °C), the addition of oxygen will not only enhance the growth rate of deposited films but also extend the region of diamond formation. At low temperatures (<500 °C), the oxygen plays an important role in diamond film growth by preferentially etching the non-diamond carbon. Without the addition of oxygen, the films deposited at high temperatures (>900 °C) were either graphitic or diamond containing a large amount of graphitic or amorphous carbon and at low temperatures (<500 °C) were white, soot-like coatings which were easily scraped off. The quality of the deposited films was characterized by Raman spectroscopy and scanning electron microscopy.

This study been conducted and applied in Alrashed Health Center/Mahmodia Sector/ kerigh Sector/Ministry of Health/Baghdad City, and conducted on samples of women who are suffering from iron deficiency (Hemoglobin%) in blood for the year 2013. Fifty women been selected (married, unmarried), their ages ranging between 19-40 years old, they been given dried grinding spinach tablet. The dose been given was 3 tablet/day/4-6 weeks, after taken the percentage of Hemoglobin and Uric acid for all studied samples before and after dried spinach tablet given. It was appeared from samples analysis primarily and statically for 50 women, that 4% upon them only suffering high Iron deficiency (8.0-9.9 mg/100ml), 38% upon them suffering from middle iron deficiency (9.0-9.9 mgl/100ml), 46% upon them who suffering from little blood Iron deficiency (10.0-10.9 mgl100ml), and only 12% % upon them who suffering from slight blood Iron deficiency (11.0-11.9 mg/100ml). Also it was appeared that none of the women suffering from high level of Uric acid in their blood.The results of the experiment declare a significant difference due to the dose of tablets dried Spinach (3 tablet/day/ 4-6 weeks), which increase the percentage of Hemoglobin in the blood by 1-1.5 degree/ week and reached the optimum percentage 12 degree and up in 4-6 weeks, with no acidity, and the undesirable test which using the medicine (Ferro-Folic tablets). Although of the above, taking of Spanish tablets doesn't effect on much increasing the percentage of Uric acid, but in small percentage and all of it lower than the normal percentage which is (7.3 mg/100ml).From all of the above we can conclude, that we are able to manufacture the grinded dried Spinach tablet and to be used as medicine to treat Iron deficiency cases and to be given to pregnant women especially in the first three months of pregnancy, due to the disability of taken the chemical medicine, due to the probable distortion happen for the fetus, and also to the individuals who are suffering from Hemolytic anemia. So, for all the above facts, this type of studies and researches should be supported and encouraged the National medicine products against the imported chemical medicine.

Coir and peat-based substrates were tested for their effectiveness in inhibiting the development of fungus gnat populations. The first experiment was conducted in July under relatively high temperatures (20 to 35 °C) and a second experiment was conducted in April under relatively low temperatures (20 °C). Euphorbia pulcherrima Willd. ex Klotzch `Freedom' plants were planted into 18-cm-diameter containers filled with substrates containing 80% sphagnum peat or coir, with the remainder being perlite. Half of the containers of each substrate were inoculated with fungus gnat larvae and sealed with either cheesecloth or thrips screen for Expts. 1 and 2, respectively. After 6 and 8 weeks for Expts. 1 and 2, respectively, fungus gnat adult and larval populations were sampled. Adults and larvae were recovered from coir and peat-based substrates in both experiments. In Expt. 1, significantly more adults and larvae were recovered from coir-based than peat-based substrates. In Expt. 2, significantly more adults and larvae were recovered from the peat-based than coir-based substrates. In a third experiment, the peat- and coir-based substrates used in Expts. 1 and 2 were used as well as the Iowa State greenhouse substrate, which contained 40% Sphagnum peat, 40% perlite, and 20% loam (v/v). Helianthus annuus L. `Pacino' seeds were sown into 18-cm-diameter containers filled with the test substrates. Natural infestation was allowed to occur for 6 weeks, after which time potato disks were used to sample the fungus gnat larvae population. Larvae were recovered from all substrates, and there was no significant difference in the number of larvae collected from the three substrates. Based on the results of these experiments, we concluded that coir does not inhibit the development of fungus gnat larvae populations and, when presented with options, fungus gnats will infest coir-based substrates as readily as peat-based substrates.

This study aims to find out the critical factors in delivering the quality of services at the Public Health Center (Puskesmas) in Sukawati District. Determination of critical factors based on Servqual Gap is a comparison between expectations and perceptions of the quality of service perceived by patients/ public health visitors. The research method is using qualitative descriptive analysis. The critical factor is determined by making a Cartesian diagram which is sourced from Serqual GAP. Data was obtained from the distribution of questionnaires to 200 respondents. The results of the data analysis concluded that there were 10 indicators in the Puskesmas Sukawati I that were categorized as critical factors that had to be corrected immediately. While Puskesmas Sukawati II there are 2 indicators that must immediately be improved. The comparative analysis shows that there is a significant difference between patient expectations and perceptions of perceived service quality. This result is certainly a consideration for the management of the Puskesmas to be able to assess the accuracy of the services provided to the community so that it can improve the quality of services in the future.
