Influence of the milling tool setup on occupational safety in furniture making.

One of the most serious causes of accidents in furniture making is kickback of machined material. The aim of this study was to determine the influence of the milling tool setup on hazards associated with kickback in furniture making. The speed of kickback was accepted as the measure of these hazards. The experiment involved controlled changes in milling tool setup, projection of cutting knives over the body of the milling tool, number of cutting knives and clearance angle. Multifactor analysis of variance was applied to the results of individual experiments, showing statistically significant factors and their interactions. Inspection and analysis of traces left by the cutting knives of the tools on the test pieces made of wood materials supported inferential statistics. The obtained results verified some common opinions and ideas on the impact of the milling tool setup on the hazards resulting from kickback in furniture making.

Statistical models to predict discharge overflow.

In the paper, a comparison of prediction results concerning the annual number of discharges of stormwater from the drainage system due to stormwater overflows is depicted. The prediction has been computed by means of storm water management model (SWMM) and probabilistic models. Regarding the probabilistic modelling some simple statistical models such as logit, probit, Gompertz and linear discriminant analysis model have been applied, and as for the hydrodynamic modelling a generator of synthetic rainfall based on the Monte Carlo method has been used. The analyses conducted has shown that logit, probit and Gompertz models give outputs that are comparable with the results of hydrodynamic modelling and are concordant with observations. Whereas the annual number of stormwater discharge predicted by the linear discriminant analysis model is significantly lower than the number obtained by hydrodynamic modelling. The calculations made have confirmed the possibility of using statistical models as an alternative for developing labour-consuming and complex hydrodynamic models. The statistical models can be used successfully to predict the stormwater overflows operation provided that the measurements of rainfall in the catchment and of filling the overflow are available.

[The statement of Polish Society's Experts Group concerning diagnostics and methods of endometriosis treatment]. / Stanowisko Zespolu Ekspertów Polskiego Towarzystwa Ginekologicznego dotyczace diagnostyki i metod leczenia endometriozy.

Endometriosis is defined by endometrial glands and stroma outside of the endometrial cavity Three types of endometriosis have been described: peritoneal endometriosis, ovarian endometriosis and deep infiltrating endometriosis. Endometriosis afflicts 6-15% of women population. It occurs mainly in the group of women in reproductive age, but also in the group of minors and approximately 3% of women after menopause. Within the group of women suffering from infertility the frequency of endometriosis increased to 35-50% of cases. Endometriosis is associated with pain symptoms which can bear the character of pain occurring periodically and altering into constant pain, dysmenorrhea, dyspareunia, dysuria and dyschezia. The correlation between the stage of endometriosis and intensity of pain symptoms not always has to be proportionate. Laparoscopy can be perceived as a standard procedure in endometriosis diagnostics as it allows simultaneous treatment. Profound interview as well as visual diagnostics (USG, MRI) should precede laparoscopy Treatment of endometriosis can be divided into pharmacological and surgical treatment, which can be invasive or non-invasive. The type of treatment depends on patient's age and her procreation plans, occurring ailments and endometriosis type. Important role is played by adjuvant treatment such as appropriate diet and lifestyle. Treatment of advanced endometriosis should be conducted in reference centres that are appointed with adequate equipment and have the possibility of interdisciplinary treatment. Presented standards can digest and outline the order of proceedings both in diagnostics and endometriosis treatment. The research group believes that the above compilation will facilitate undertaking appropriate decision in diagnosis and treatment of the disease, which will subsequently contribute to therapeutic success.

[Laparoscopic dissection of uterine artery and coagulation utero-ovarian ligament for the treatment of symptomatic myomas]. / Laparoskopowe przeciecie tetnic macicznych oraz koagulacja wiezadel wlasciwych jajników w leczeniu objawowych miesniaków macicy.

OBJECTIVES: Our purpose was to evaluate the effects and safety of laparoscopic dissection of the uterine artery and coagulation of the utero-ovarian ligament in treating symptomatic myomas. MATERIAL AND METHODS: We studied 40 women, aged 31 to 50, with symptomatic uterine fibroids undergoing laparoscopic dissection of the uterine artery and coagulation of the utero-ovarian ligament Ultrasound examination of uterus and dominant fibroid were performed. Their volume reduction was measured. Clinical response was evaluated according to questionnaire assessing the level of menstrual bleeding, pain and urgency. RESULTS: There were no complications during operations. Within 6 months after the surgery the mean uterus volume was reduced by 22% and mean volume of dominant fibroid was reduced by 51%. Six months after the surgery menstrual bleeding was reduced in case of 34/38 patients (85%), completed pain relief has been observed in case of 19/25 patients (76%). In case of 11/15 (73%) patients, a regression of urgency has been observed. CONCLUSIONS: Laparoscopic dissection of the uterine artery and coagulation of the utero-ovarian ligament is a safe and effective method of treating symptomatic myomas. It is an alternative to hysterectomy, especially for women who wish to preserve their uterus.

[Perspectives of endometriosis treatment]. / Perspektywy leczenia endometriozy.

In recent years a dynamic development of research on endometriosis has been observed. Complex and not definitively recognized etiopathogenesis, impedes diagnostic progress and effective treatment. Frequent incidence of endometriosis in reproductive age and high percentage of the illness in the group of patients with infertility, both determine the importance of that issue. The article below presents the latest lines of research on efficient therapeutical scheme, covering reproductive abilities. Attempts of implementation of aromatase inhibitors, selective estrogen receptor modulators, immunomodulators and antiinflammatory agents have been described. Considering groups of medicines mentioned in the article, the outcome of examination using aromatase inhibitors, immunomodulators mainly IL-2, INF-alpha-2b, as well as antiinflammatory agents--recombinant human TNF binding protein-1, seem to be most encouraging. Part of the survey was conducted on animal models therefore it requires verification of usefulness and effectiveness on people. The results are very promising, they set the trend of future research aimed at application of modern and efficient treatment of endometriosis.
