Health Problems in Changing Communities by A Volcanic Disaster

这座山的火山喷发。从1990年开始的温泉-福根，到1995年已经停止，但岛原市和福凯镇的许多居民仍然因为人类环境系统的变化而与许多困难发生冲突。通过对火山喷发的连续研究发现：1)灾区人口因避难而迅速减少，以避免急性喷发。尽管即使在活跃的火山喷发结束后，岛原市的这一趋势仍在继续，但Fukae的人口已经通过社会增长恢复。从第一产业(农业)向第三产业的产业转移可能对这种人口流动起到一定的作用。2)随着皮疹的减少，眼部和喉部刺激性症状迅速减少，但呼吸系统刺激性症状逐渐减少。3)通过对学龄儿童哮喘与家庭环境关系的分析，火山喷发后家庭成员的变化似乎对哮喘发作的患病率有显著影响。4)随访研究发现，即使火山灾害已经结束，过去的难民的心理健康状况仍然很紧张。心理卫生管理是预防创伤后精神障碍的必要手段。总而言之，可能有必要重新组织和/或重建当地社区，以保持长期遭受灾难性自然灾害的居民的高生活质量。

The volcanic eruption of Mt. Unzen-Fugen which began in 1990, has ceased in 1995 but many dwellers in Shimabara city and Fukae town are still conflicting with many difficulties by change of human environmental system. Our continuous study through volcanic eruption revealed following points.1) Populations of disastrous area had rapidly decreased by refuge of dwellers for avoiding acute eruption. While this trend still continues in Shimabara city even after the end of active volcanic eruption, the population in Fukae has recovered by social increase. The industrial transition from primary sector (agriculture) to tertiary may act some role for such population movement.2) According with decline of eruption, irritant symptoms in eyes and throat have rapidly became to be less frequent., but those in respiratory system have slowly decreased. Chronic effects on respiratory system should be continuously examined.3) By analysis on relationship with asthma and domestic environment among school children, changes of family member by volcanic eruption seemed to affect significantly the prevalence of asthma attack.4) Follow up studies revealed that mental health condition of past-refugees has been still stressful even though the volcanic disaster has ceased. Administration on mental health care should be necessary for preventing Post Traumatic Disorders. As a conclusion, the re-organization and/or re-construction of local communities might be necessary for keeping high level of quality of life among dwellers who met disastrous natural hazards for long period.
