Three varieties of green pepper - Chungyang pepper, Cucumber-taste pepper and Nokgwang pepper - are competing with one another in consumption due to the overlapping shipment period. The objective of this study is to analyze the influence of monthly variations of shipment quantities on the wholesale market prices. A Linear Approximated Inverse Almost Ideal Demand System (LA/IAIDS) is employed with monthly data set of three different varieties of green pepper consumption. The results show that if there is an excess supply in the market, the rate of the price decline is larger for forcing culture Chungyang pepper than other pepper varieties. On the contrary, change in supply of cucumber-taste pepper and Nokgwang pepper has little effect on the price of Chungyang pepper. The results of this study can be utilized as a basic information for enhancing the farm income and promoting agricultural policies related to the establishment of self-help funds by Chungyang pepper producer groups in Gyeongnam region.

Purpose: The contextual interference effect is a theory crucial for explaining the importance of efficient practice and its application in the field, and representative hypotheses on the theory are elaboration hypothesis and reconstruction hypothesis. as the recent studies on contextual interference by Lin et al. (2008, 2009, 2010) and Cross et al. (2007) support different hypotheses, this study purposed to examine the time point and tasks of interest in order to compare the result of the two hypotheses Methods: The subjects were 36 right‐handed male and female adults aged between 19 and 32, and they were divided into two groups (n=18 each) at random according to practice condition (blocked practice/random practice). In each group, 9 subjects were given transcranial magnetic stimulation(TMS) before task performance and the other 9 were given TMS after task performance. In the test, key pressing response time was used, and each group had the acquisition phase (1st day), and retention test and transfer test (2nd day), and then response time measurements were analyzed statistically Results: When TMS was given after task performance in the acquisition phase, the performance level was lower in the blocked practice group, but in the retention test when TMS was given before task performance the stimulation hindered the random practice group’s learning and lowered its performance level and consequently the contextual interference effect did not occur. Conclusion: After task performance in the acquisition phase, the information process occurs between tasks in the resting phase, and at the same time, the information process occurs in the preparation phase before task performance and affects learning. Accordingly, both the retention phase before task performance suggested by the reconstructive hypothesis and the resting phase after task performance suggested by the elaboration hypothesis can be the time points when contextual interference occurs between tasks, and therefore it is concluded that the reconstructive hypothesis and elaboration hypothesis may coexist with each other.

본 연구는 골프 퍼팅시 숙련성과 거리에 따른 시각탐색과 주의집중 요인을 분석하여 그 차이를 밝히고자 시행되었다. 이를 위하여 인천광역시의 H 아카데미와 K 아카데미에 소속되어 있는 회원 50명 중 KPGA 자격기준에 따라 숙련자와 비숙련자 각각 8명씩, 총 16명을 비확률적인 목적표집법으로 선정하였고, 선정된 대상자는 골프 퍼팅과제(1M, 5M)를 실시하였다. 과제수행 시 실제 눈의 움직임을 관찰하기 위해 Eye Mark Recorder-9(EMR-9)를 사용하였으며, 이를 통해 얻은 시선 고정 값을 분석하기 위해 이원분산분석(two-way ANOVA)을 실시하였다. 또한 주의집중요인을 분석하기 위하여 반 구조화면담법을 통해 자료를 수집하여 귀납적 내용분석을 실시하였다. 그 결과 숙련성에 따라 준비단계와 스윙단계에서 각각 유의한 차이가 나타났으나 거리에 따른 차이는 유의한 차이가 나타나지 않았다. 또한 주의집중의 요인에서도 차이가 나타났다. 따라서 퍼팅기술에 있어 운동숙련을 결정짓는 지각기술 및 주의집중요인은 초보자 및 중간 숙련자 지도 프로그램을 활성화 시키는데 기초 자료로 활용될 것으로 기대한다.

본 연구는 협동적 집단게임 활동이 유아의 역할수용능력에 긍정적인 영향을 미치는지를 알아보는데 목적이 있으며 이를 통하여 협동적 집단게임을 통한 교수·학습방법의 기초자료를 제공하는데 그 의의가 있다. 유아의 역할수용능력 검사를 위하여 Selman과 Byrne(1974), Flavell, Botkin과 Fey(1968), Landry와 Lyons-Ruth(1980)의 과제를 이미진(1985)이 번안·수정하고, 이현경(2000)이 재수정한 검사 도구를 사용하였다. 연구 결과 첫째, 협동적 집단게임 활동은 유아의 역할수용능력에 유의미한 수준에서 차이가 있는 것으로 나타났다. 둘째, 협동적 집단게임 활동에 따른 유아의 역할수용능력은 성별에 따라 유의미한 수준에서 차이가 나지 않았다.
