Magistriniame darbe išanalizuoti projektų valdymo metodai ir algoritmai, išnagrinėti darbų kalendorinio grafiko sudarymo principai, sukurtas statybos darbų grupavimo ir darbo laiko paskaičiavimo konceptualus modelis ir išreikštiniai algoritmai dviems grupavimo scenarijams. Išvestos formulės darbo kiekiui sąmatoje, objekte ir komplekse apskaičiuoti. Pasitelkus projektų valdymo teoriją, sukurtas MS Project COM programinis priedas SDKG, leidžiantis statybos vadovui modeliuoti statomo objekto kalendorinį darbų grafiką. COM priedo programavimo darbai atlikti Microsoft Visual Studio Profesional 2005 aplinkoje, pasinaudojus Visual Basic 2005 programavimo galimybėmis. Atlikti duomenų iš sąmatos nuskaitymo, išsaugojimo, projekto duomenų įkėlimo, grafiko nubrėžimo laikų priklausomybės nuo sąmatos apimties tyrimai. Išvesta formulė minimalaus pelės paspaudimų skaičiaus radimui, priklausomai nuo darbų ir grupių skaičiaus. Darbo rezultatai įdiegti statybos įmonėse UAB “Armobetas” ir UAB “Merko statyba”. / Project management methods and algorithms have been analysed in this master paper. Schedule making principles have been considered. Construction work grouping and work time conceptual model and explicit algorithms for two grouping scenarios have been developed. Using project management theory, MS Project COM add-in called SDKG has been developed. This add-in allows the construction supervisor to model the schedule of the object under construction. The add-in has been developed in MS Visual Stuodio 2005 environment using Visual Basic 2005. An investigation to study data retrieval from an estimate, saving, project data deploying and plotting time dependencies on the estimate volume has been carried out. A formula to find the minimal number of mouse clicks depending on the number of works and groups has been derived. The results obtained have been applied in construction companies UAB „Armobetas“ and UAB „Merko statyba“.

In Sweden, sickness absence due to mental disorder is increasing for both men and women, although more among women. The psychosocial work environment is acknowledged as an important predictor for sickness absence. Employee based work-time control is beneficial for the balance between job stress and recovery and could therefore be of interest when aiming to prevent sickness absence. The aim is to investigate the association between control over daily hours (CoDH) and control over time off (CoT), respectively, and sickness absence. The study also examine whether the association differ by gender and if burnout or depression mediates the associations. Data was derived from two waves of the Swedish Longitudinal Occupational Survey of Health (SLOSH) which is an approximate representation of the Swedish working population (n=8418, of which 4936 were females). Binary logistic regression was used as method of analysis. After adjustment for possible confounders, no association between CoDH and sickness absence was found. Low CoT was significantly associated with sickness absence among men (OR=0.90 [0.84, 0.96]), but not among women. Neither burnout nor depression mediates the associations. CoT is stronger associated with sickness absence than CoDH. CoT with regard to sickness absence is of greater importance for men than women.
