A study of wood and bark residue disposal in the forest products industries

A preliminary report to the Fifty-fifth legislative assembly, February 1969. This is a preliminary report of a two-year study that was authorized by the Fifty-fourth Legislative Assembly in 1967. The study was aimed at providing means of lessening air pollution from disposal of wood and bark residues by forest products industries. The final re­port summarizing conclusions of the study will be published in August 1969. Included in the study are a statewide survey of wood and bark residues; a transportation cost study; an investigation of three methods for disposing of residues, 1, burning in a wigwam burner, 2, burning in other types of incinerators, 3, disposal by landfill; and an investi­gation of three means of utilization: 1, as fuel, 2, on the soil, and 3, wax extraction from bark. In Oregon, use of wood residues for paper and composition board manufacture has increased greatly in the last 14 years. Only 6 percent of woo::! residues from sawmills and plywoo::l plants was used for paper and composition board in 1953, compared to about 60 percent in 1967. Quantity of residues being burned in wigwam burners has been conse­quently reduced in recent years. Utilization will continue to increase in the future and quantities of wood and bark requiring disposal will decrease.KEYWORDS: Wood waste, Bark as fuel, Mulchin

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Industry Appraisal of Forest Products Curriculum at Oregon State University

The Forest Products Department at Oregon State University trains professionals who work mainly in the forest products industry. Therefore a survey was conducted to assess the relevance of our curriculum to the needs of our graduates. A total of 1,183 questionnaires were mailed to persons in industry, of which 730 were completed and returned Respondents were asked to rank the importance of them of 59 subjects, courses, or disciplines within the university. Other questions related to respondents' type of manufacturing operation, management level in the firm, held of training, length of time with firm, age, level of education, and most helpful sources of education. Analyses were made for Oregon State University graduates in Forest Products as a group, and for groups sorted by management level, type of operation within the industry, and age level of respondents
