日本的城市环境问题及其改善过程：政策和规划视角研究

日本是亚洲最先城市化的国家,目前已有86%的人口生活在城市行政区范围内。在城市化的进程中,日本曾出现过各种各样的环境问题,经过半个多世纪的努力,现在的城市生活环境不仅得到根本改善,而且在资源循环利用和低碳社会建设等方面也做出引人注目的成绩。本文从日本城市规划制度和环境政策演变角度,分阶段介绍自1950年以来的城市环境问题、环境法律和有关城市规划建设的政策,逐步展开日本改善城市生活环境、保护地球自然环境的过程,尤其注重从生态城市到低碳社会转型发展的最近政策动向。     

A detailed analysis of musculoskeletal disorder risk factors among Japanese nurses

INTRODUCTION: Although Musculoskeletal Disorders (MSD) represent a common occupational problem, few epidemiological studies have investigated MSD risk factors among Asian nurses, particularly those in Japan. METHOD: We administered a modified Japanese-language version of the Standardized Nordic Questionnaire to 1,162 nurses from a large teaching hospital. MSD categories focused on the neck, shoulder, upper back, and lower back regions. RESULTS: A total of 844 completed questionnaires were analyzed (response rate: 72.6%). The 12-month period-prevalence of MSD at any body site was 85.5%. MSD was most commonly reported at the shoulder (71.9%), followed by the lower back (71.3%), neck (54.7%), and upper back (33.9%). Alcohol consumption, tobacco smoking, and having children were shown to be significant risk factors, with adjusted Odds Ratios of 1.87 (95%CI: 1.17-2.96), 2.45 (95%CI: 1.43-4.35), and 2.53 (95%CI: 1.32-4.91), respectively. Workplace risk factors included manually handling patients (OR: 2.07 to 11.97) and undertaking physically laborious work (OR: 2.09 to 2.76). Nurses reporting pre-menstrual tension were 1.66 and 1.94 times more likely to suffer from lower back and upper back MSD, respectively. High mental pressure was also identified as a significant risk factor for MSD of the neck (OR: 1.53) and shoulder (OR: 2.07). IMPACT ON INDUSTRY: The complex nature of MSD risk factors identified during this study suggests that remediation strategies which focus only on manual handling tasks would probably be suboptimal in reducing MSD among nurses. Therefore, to help alleviate their considerable MSD burden, a greater emphasis will need to be placed on job satisfaction, work organization, and occupational stress, as well as the more traditional hazard reduction strategies such as manual handling, work tasks, and other occupational factors.

Atmospheric mercury over the marine boundary layer observed during the third China Arctic Research Expedition

TGM measurements on board ships have proved to provide valuable complementary information to measurements by a ground based monitoring network. During the third China Arctic Research Expedition (from July 11 to September 24, 2008), TGM concentrations over the marine boundary layer along the cruise path were in-situ measured using an automatic mercury vapor analyzer. Here we firstly reported the results in Japan Sea, North Western Pacific Ocean and Bering Sea, where there are rare reports. The value ranged between 0.30 and 6.02 ng/m³ with an average of (1.52 ± 0.68) ng/m³, being slightly lower than the background value of Northern Hemisphere (1.7 ng/m³). Notably TGM showed considerably spatial and temporal variation. Geographically, the average value of TGM in Bering Sea was higher than those observed in Japan Sea and North Western Pacific Ocean. In the north of Japan Sea TGM levels were found to be lower than 0.5 ng/m³ during forward cruise and displayed obviously diurnal cycle, indicating potential oxidation of gaseous mercury in the atmosphere. The pronounced episode was recorded as well. Enhanced levels of TGM were observed in the coastal regions of southern Japan Sea during backward cruise due primarily to air masses transported from the adjacent mainland reflecting the contribution from anthropogenic sources. When ship returned back and passed through Kamchatka Peninsula TGM increased by the potential contamination from volcano emissions.     

柳州以酸雨治理促城市生态转型--柳州市以环保促经济升级城市转型服务民生的示范作用

柳州市这个“十雨九酸”的工业城市在经济升级、城市转型的过程中,完美实现了向“生态宜居”城市的战略转变。1994年国家有关部门把柳州市酸雨治理列为第四批日本海外经济协力基金贷款项目。这一项目开启城市环境治理新纪元,带动柳州经济发展方式的转变,促进柳州从“污染城市”到“创建环保模范城市”的跨越,“贷”动了柳州是从政府部门环保对策、城市环保质量到公众环保意识的全面提升,助力酸雨柳州的生态转变,在西部地区经济与环境协调发展和促进资源节约型和环境友好型工业城市发展方面具有重要的示范作用。     

日本处理城市生活垃圾的做法及启示

随着我国城市化进程的加快，城市生活垃圾的排出量急剧增加，造成环境污染问题日益严重。垃圾不但影响城市景观，传播疾病，而且还破坏环境，浪费资源。本文通过介绍日本处理城市生活垃圾的做法和效果，比较我国处理城市生活垃圾的现状，提出我国应发挥政府职能作用，加强对国民的环保宣传和教育，建立垃圾分类制度、细化标准，创新垃圾回收处理技术，鼓励和扶持垃圾回收产业体系等建议。
