M. Tech. Business Administration / One of the challenges facing analytical laboratories is to satisfy customer needs. Organisations are striving to achieve high levels of customer satisfaction. Service providers, like analytical laboratories, are faced with different problems that challenge customer satisfaction: turn-around time, quality of service, employee skills levels, cost, and customer retention. This research was conducted in order to identify and understand factors contributing to customer satisfaction.

Baigiamajame darbe nagrinėjamas Vilniaus Gedimino technikos universiteto specialiose laboratorijose esančių įrengimų skleidžiamas triukšmas bei jo atsiradimo dėsningumai. Garso lygiui išmatuoti buvo atlikti eksperimentiniai matavimai. Garso lygiai matuoti ir rezultatai įvertinti pagal higienos normoje HN 33–1:2003 pateiktus reikalavimus. Rezultatai pateikti grafiškai ir atlikta jų analizė. Baigiamajame darbe taip pat pateikta apibendrinta keliamos problematikos analizė, triukšmą mažinančių priemonių apžvalga ir analizė, pasiūlytos triukšmą mažinančios priemonės tiriamose laboratorijose. Išnagrinėjus ir nustačius triukšmo šaltinių keliamo garso lygį ir jo atsiradimo dėsningumus, pateikiamos baigiamojo magistro darbo išvados ir pasiūlymai. Darbą sudaro penkios dalys: įvadas, apžvalginė – metodinė dalis, tiriamoji dalis, išvados ir pasiūlymai, literatūros sąrašas. / Noise outspread originated from machines located in laboratories of Transport engineering and Construction engineering faculties of Vilnius Gediminas Technical University and its origination consistency is being investigated in this article. To evaluate the level of sound there was taken experimental measurements. The level of sound measuring and the measurement results evaluation have been made according to requirements prescribed in Lithuanian hygiene standart HN 33 – 1:2003. Investigation results have been presented graphically, their analysis has been made with drawn inferences. There is summarized arisen problem analysis represented in this graduation work. Moreover it is presented review and analysis of noise abatement means, suggested these means implementation possibilities into laboratories. After investigation of the level of sound produced from noise origin and after determination of its originating consistency, conclucions and suggestions have been represented in this final graduation work. This work consists of five parts: introduction, methodical – review part, research part, conclusions and suggestions, list of literature.

The aims of the study were to review the literature on the currently known adverse health effects of formaldehyde vapour exposure, to measure environmental formaldehyde levels before and after engineering controls were implemented, to measure symptoms of formaldehyde exposure when compared to non - exposed controls and to evaluate the effectiveness of engineering controls in reducing the symptoms associated with formaldehyde vapour exposure in anatomy students at the Faculty of Medicine, University of Natal. Pre and post intervention environmental monitoring surveys were conducted over the period July 1993 to September 1995 in the aforementioned Human Anatomy Laboratory using passive diffusion badges which were then analyzed by an approved laboratory in Johannesburg. Ambient air temperature, humidity and ventilation rates were measured simultaneously using appropriate instruments. Self-administered questionnaires, relating to the symptoms of exposure to formaldehyde vapours, were obtained from all anatomy students over a two year period before or after as well as during their exposure to the laboratory environment, as well as from all exposed staff members (including their control group). Nasal epithelial scrapings of staff members and a control group were subjected to cytological examination by the Cytology Department of the Provincial Pathology service, at the pre - intervention phase. The environmental monitoring data of 1993 and 1994 indicated that the ambient levels of formaldehyde vapour exceeded the American (ACGIH) Threshold Limit Value (TLV) and thus posed a potential health risk to students and staff, this was due to inadequate ventilation in the Human Anatomy Laboratory. An intervention in terms of ventilation controls was implemented and proved to be effective in reducing formaldehyde vapour levels and reported symptoms in the cohorts studied, comparing each group to themselves, however, the reported symptom levels did not drop significantly in the group exposed after the intervention compared to the group surveyed at the pre - intervention phase. Whether this reduction is sufficient to prevent long term health effects such as neoplasms and sensitization remains to be established. Hence it is recommended that alternative control methods should be considered. / Theses (M.Med.)-University of Natal, 1996.

A survey was conducted to answer two basic questions: 1) What are the medical bacteriology laboratories of Indiana using as criteria for identifying microorganisms? and 2) What is the basis for these criteria? The author developed a questionnaire used as the survey instrument. One hundred fifty questionnaires were mailed to medical laboratories throughout Indiana. Sixty percent of the laboratories responded. This study lists all responses and gives a description and/or evaluation of each procedure.In addition, the researcher discusses some of the factors influencing the type of procedures that are being used. Data collected by this research will be submitted to the biology department at Ball State University to help establish more concrete guidelines that can be used to update course content.
