Učestalost mišićno-koštanih i očnih simptoma kod rada s računalom

Computer users most often complain of the eye and locomotor system disorders. The goal of this paper was to find out the frequency and relation between musculoskeletal and eye symptoms among computer workers. The data on musculoskeletal and eye symptoms were provided by two questionnaires. Forty-nine workers were included in the study. Their mean age was 41 years and average length of service 16 years. The average amount of time they spent in front of computers was 6.73 hours per day. Women spent more time working at a computer per day than men (P=0.025). The most frequent complaint in the past year referred to the upper back pain (30.6 % of the workers). Every fourth worker, i.e. 24.5 % of them experienced neck pain in the past year; women more often than men (P=0.024). A health problem which reduced the range of motion and prompted the workers to ask for sick leave was lower back pain. The relation between eye symptoms and the upper back pain experienced in the past year (P=0.004), and in the last week (P=0.031) was statistically signifi cant. Proper exercises for stretching musculoskeletal system, ergonomic computer equipment, and artificial tears could decrease muscular and eye problems, which in turn could enhance productivity and reduce sick leaves.tegoba očiju i mišićno-koštanoga sustava kod radnika koji rade s računalom i njihovu povezanost. Pomoću upitnika uzeti su podaci o mišićno-koštanim i očnim simptomima kod rada s računalom. U ispitivanju je sudjelovalo 49 radnika (27 žena i 22 muškarca) prosječne životne dobi od 41 godina i prosječnog trajanja radnog staža od 16 godina koji dnevno rade za računalom u prosjeku 6,73 sata. Žene su značajno duže dnevno radile na računalu od muškaraca (P=0,025). Najviše se radnika žalilo na bolove u gornjem dijelu leđa u zadnjih godinu dana (30,6 %). Svaki četvrti radnik, tj. 24,5 % radnika imalo je bol u vratu u zadnjoj godini i to statistički značajno češće žene (P=0,024). Tegobe koje ograničavaju aktivnost i mogu zahtijevati bolovanje bili su bolovi u donjem dijelu leđa. Statistički je bila značajna povezanost pojave očnih simptoma i bolova u gornjim leđima u zadnjoj godini (P=0,004) i u zadnjem tjednu (P=0,031). Odgovarajuće vježbe rasterećenja mišićno-koštanoga sustava uz ergonomsku opremu za rad s računalom te smanjenje očnih tegoba upotrebom umjetnih suza potrebno je provoditi radi smanjenja mišićnih i očnih tegoba, što zajedno povećava produktivnost i smanjuje bolovanja

Region as a Basic Territorial Unit of Regional Development (Concepts and Types)

The authors analyze and summarize the history of the development of the region,meaning of the term region and types. The paper analyzes the regions as basic territorial units which are important for regional development, the area in which establishes and implements regional development policy. The concept of the region is seen dynamically, in a historical context. The subject of the work is focused on the study of the phenomenon of the region as a territorial unit for the preparation and implementation of regional development policy for the purpose of equitable development. The authors analyzed different concepts and underlined the most important characteristics of the idea region and its types. Based on the analysis, definitively that the region is starting and basic territorial unit for planning and implementation of sustainable policies for regional development

Kartografija Crne Gore s naglaskom na prve domaće karte Crne Gore

This work discusses cartographic attractiveness and representation of the Montenegrin “historic spaces” in the context of the Great Powers spheres of influence and their imperial assessment of the cartographic material. It gives an overview of the “historic space” of Montenegro between the 4th and 20th century, esp. in Ancient, Medieval and Modern Ages, placing special emphasis on the earliest and subsequent domestic/local maps.Radi se o kartografskoj interesantnosti i zastupljenosti “istorijskog prostora” Crne Gore u kontekstu sfera velikih sila i njihovog prikazivanja. Prati se kartografija od IV do XX vijeka, s naglaskom na prve domaće karte Crne Gore u XIX vijeku

Good clinical practice: International quality standard for clinical trials

A clinical trial is one of the most important examples of experimental studies. Clinical trials represent an indispensable tool for testing, in a rigorous scientific manner, the efficacy of new therapies. Good Clinical Practice is an international ethical and scientific quality standard for clinical trials, concerning the design, conduct, performance, monitoring auditing, recording, analysis and reporting. This is an assurance to the public that the rights, safety and well-being of trial subjects are protected, and that clinical trial data is credible. The above definitions are consistent with the principles that have their origin in the declaration of Helsinki. The objectives of Good Clinical Practice are to protect the rights of trial subjects, to enhance credibility of data and to improve the quality of science

Step-By-Step Procedure and Tools to Reduce Work-Related Stress

Based on available guidelines, protocol, etc., of the EU countries as well as evaluated results of the taken measures, step-by-step procedures are proposed as well as the tools of occupational medicine specialist for the identification of stressors and measures that should be taken to reduce stress at work. European Pact for Mental Health and Well-Being has focused its commitment on workplaces and a necessity to promote work settings, to create the atmosphere for mental health promotion emphasizing reconciliation between work and family life, to introduce a program for stress prevention at work and health promotion in the workplace and to support employment, rehabilitation and return to work of the workers with mental health issues and disorders. Any risk assessment at work, especially of psychosocial risks, requires support of employers and active participation of workers. For that reason, “fight against stress” should become a company’s policy. A number of procedures that follow are presented by diagrams that lead through methods of analysis and identification, from selection of measures for stressor reduction to the final evaluation. It is a cycle that ends by defining the term for a new analysis and assessment of psychosocial risks followed by the beginning of another cycle

ASSIGNMENT OF 1H AND 13C NMR SPECTRAL DATA OF DIASTEREOMERIC ACETALS DIRECTLY FROM THEIR MIXTURE BY SPECTRAL SIMULATION

Herein, an NMR spectral analysis was performed of a mixture of diastereomeric acetals synthesized from 2-fluorobenzaldehyde and a racemic mixture of 4-methylpentan-2-ol. The simulated 1H- and 13C-NMR spectra of individual diastereomers, as well as their superimposed and summed spectra, were compared with the obtained experimental spectra. Spin simulation of proton signals was particularly useful for the assignment of the aromatic part of the molecules and of the diastereotopic protons of the methylene groups. The isomer NMR spectral data – chemical shifts, coupling constants, HMBC and NOESY interactions were systematized in appropriate tables and schemes
