본 연구는 널리 알려져 있으면서도 한편으로는 제대로 인식되지 않은 삶의 한 가지 방식으로서 구조주의적 가정의 관점으로 현재 유아교육현장에서 발생하는 언어현상의 문제들을 해석해 보고 이러한 문제들에 대한 개선방안을 구조주의의 한계를 비판하면서 출현한 후기구조주의적 접근을 통해 논의해 보았다. 연구의 결과 구조주의적인 관점에서 유아 교실의 언어현상은 초월적 기의의 존재, 개체의 존엄과 본질의 외면, 언어와 사고의 경직성이라는 문제점을 가지고 있었고 이에 대한 후기구조주의적 관점에서의 해결 방향은 초월적 기의의 해체, 개체와 본질의 존엄성 찾아가기, 언어의 시적 기능 회복하기라는 세 가지로 제시되었다. The purpose of this study expolres the language phenomena of early childhood classroom from Post-Structualistic perspectives. In order to achieve this purpose, the characteristics of language to generate in early childhood classroom was firstly discussed from structualistic perspectives. The result was that currently language to generate in early childhood classroom is very structualistic and can't reflect children's real life context. Therefore, In this study, to solve the ploblems of currently language to generate in early childhood classroom, researcher suggest that from post-structualistic perspectives the language to generate in early childhood classroom should be rethinked. On post-structualistic perspectives the early children's language should be reflect children's real life context and recover poetic function of language.

Ju Rak Lim,Ju Kim,Seong Soo Cheong,Dong chil Choi,Chang yeon Hwang 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10

This study was conducted for establishment of Economic injury levels(EILs) of the tea red spider mite, Tetranychus kanzawai on Rubus coreanus. T. kanzawai was innoculated on May 7 in differently 0, 5, 10, 20 and 40 adults per plant. And pesticide was treated in late April, early May, middle May and late May, respectively. After inoculated of T. kanzawai, the density was increased until the mid-June and decreased gradually in all plots. And higher inoculation density were increased higher than lower inoculation density. Growth variables were not different among experimental plots except number of fruit set, but the number of fruit set and yields were decreased with increasing initial mite density. Densities of T. kanzawai on treated time of pesticide was lower in later treatment time than early treatment time. The late April treatments were not effective of pesticide in harvesting season. The rates of yield loss increased with increasing initial mite density. The relationship between initial T. kanzawai densities and yield losses was well described by a linear regression, Y = 0.6545X + 3.0425, R2=0.9313. Based on the relationship, the number of adults per plant which can cause 5% loss of yield was estimated to be approximately 3.0. And EILs was estimated to be approximately 8.3 adults/leaf in mid-May.
