A basic study on the social factors in the diversification of Ryuukyuuan dialects.

为了动态地把握琉球方言的多样化或变化趋势，1996-1997年的调查从以下几个方面进行：1）通过田野调查和邮件调查，对平良市的方言意识进行调查2）通过田野调查对平良市及其周边地区的方言变化进行调查1）调查居住在平良市的男性原住民对宫古方言、县政府所在地的那霸方言和标准日语的印象，在1996年和1997年执行。通过与1994年在那霸市同样收集的另一个数据进行比较，可以看出，宫古的传统方言和标准方言之间产生的方言间关系从来没有像那霸那样巩固过这种独立的地位，在那霸，方言间关系的地位是如此确定，以至于人们将第三种变体命名为Uchinaayamatuguchi。在方言意识调查的同时，对宫古方言的变异进行了基础性研究，特别是对宫古大陆北方方言、大上方言、Karimata方言、池间方言的变异进行了研究。这些方言的语音资料由DAT记录下来，质量很好，1988年，作为本研究项目的报告之一，出版了《大上方言的语音、词形和语法，参考Karimata方言》（CD及其解释）。

To grasp the trend in the diversifications or changes in the Ryuukyuuan dialects dynamically, the investigation in 1996-1997 has been executed through the following points of view, focusing on Miyako archipelago where such survey has been hardly reported.1) survey on the dialect consciousness in Hirara city through the investigation by field research and mail2) survey on the dialectal variations observed in and around Hirara city by field resarchAs for 1), the investigation of images held by male native people dwelling in Hirara city against Miyako dialect, Naha dialect spoken in the city of prefectural government, and standard Japanese, was excuted in 1996 and 1997. By the comparison of this data with another data which was collected likewise in Naha city in 1994, it became evident that the interdialect generated between conventional dialect and standard in Miyako has never connsolidate such inndependent status as observed in Naha, where the interdialect have had so confirmed status that people has named the third variation as Uchinaayamatuguchi.As for 2), in parallel with the survey on dialectal consciousness, the basic research on the dialectal variations resulted from the ever-occurred diversification in Miyako arhipelago, especially in the northern dialects of Miyako mainland, Oogami, Karimata, Ikema. Sound data of these dialects was recorded by DAT with good quality, and The Sound of Oogami Dialect, wordform and grammar, with reference to Karimata Dialect (CD and its explanation) was published in 1988 as one of the reports by this research project.
