        The purpose of this paper was to introduce positive psychology, to the fields of SLA and English education in Korea. Positive psychology investigates how people flourish and seeks the virtues and strengths of humans. It focuses on the factors enabling people and their communities to thrive, instead of focusing on psychological disorders and abnormalities, longstanding issues of general psychology. Its three main research topics include positive emotions, traits, and institutions, all of which have relevance to SLA and L2 education. This paper examined how these topics have been approached in SLA. Much attention has focused on positive emotions, particularly, enjoyment, which has gained momentum in recent years with publications. Empirical studies of the impacts of positive emotions on L2 learning were reviewed with discussion of enjoyment. The paper concludes by discussing directions for future research, applying positive psychology to Korean EFL contexts.

        본 연구는 시설토마토 재배지에서 push-pull 전략을 이용해 담배가루이와 천적곤충의 행동을 제어함으로써 담배가루이(Bemisia tabaci)를 친환경적으로 방제하기 위한 기술을 개발하고자 수행하였다. 담배가루이는 노란색에 유인율이 가장 높았으며, 520 nm의 광원에는 유인반응을 복합광원인 450 + 660 nm의 광원에는 회피반응을 보였다. 천적곤충인 담배장님노린재(Cyrtopeltis tenuis)와 미끌애꽃노린재(Orius laevigatus)는 모두 520 nm의 광원에 가장 높은 유인반응을 보였다. 휘발성 물질로는 ocimene과 carvacrol에 대해 기피반응을, methyl isonicotinate에는 유인반응을 보였다. 토마토 온실에 메밀을 투입하였을 경우 천적곤충인 담배장님노린재의 밀도는 무처리 대비 15일간 약 16배로 높게 유지되었다. Push-pull 세부전략들을 종합 처리한 결과, 처리 50일 경과 후 담배가루이의 트랩당 밀도는 무처리 대비 3배 이상 낮게 나타났으며, 이에 따른 시기 별 방제효과는 시간이 경과함에 따라 증가하는 경향을 보인 가운데 최고 68.7%였다.

        This study was conducted to develop a technology for environmentally friendly control of Bemisia tabaci by a push-pull strategy in tomato greenhouse. B. tabaci was most attracted to the light source of 520nm, whereas it showed an avoidance response to the complex light treatment of 450+660nm. Two natural enemies, Nesidiocoris tenis and Orius laevigatus were attracted to 520nm. B. tabaci was repellent to volatile organic compounds, ocimene and carvacrol, while methyl isonicotinate showed attractant response. When buckwheat was added into the greenhouse, the density of N. tenis was maintained at about 16 times higher for 15 days. As a result of the combined treatment of push-pull strategy, the density of B. tabaci was 3 times lower and the control effect increased with time and reached up to 68.7%.

        The primary purposes of this study are to identify the characteristics of modeling a rater training program and to develop an efficient training model at the University of Illinois at Urbana-Champaign. For these purposes, this study proposes that a rater training program should be standardized by accomplishing innovative systematic changes that consider multiple aspects. This study utilized a modified version of Lynch’s program evaluation model (1996, 2003) to collect evidence from different sources, including data drawn from the entire evaluation process ranging from needs analysis to a feedback system based on the final product of the evaluation. Mixed methods were proposed for the data analysis. Quantitative data analysis was proposed for analyzing the surveys, and the rating corpus. Qualitative and document analysis were also essential for analyzing relevant training materials and workshop observation as well as exploring the degree of change in the perceptions of the raters. The results of this study provide educational implications for language testing. The salient value of this study is the collaboration with stakeholders in a test administration situation. Raters’ concerns and challenges were clearly identified, shared, and resolved with the practitioners.
