본 연구는 또래도우미 활동의 참여에 대한 자발성이 장애학생 수용태도에 미치는 영향을 살펴보는데 목적이 있다. 이를 위해 부산광역시 소재 초등학교 장애학생 3명과 그 장애학생이 속한 3개의 통합학급 일반학생 각 16명씩을 실험집단1, 실험집단2, 통제집단으로 하여 총48명을 대상으로 하였다. 일반학생의 장애학생에 대한 수용태도 측정을 위해 안승숙(2002)의 설문지를 수정ㆍ보완하여 사용하였고 또래도우미 활동은 장혜영(2011)이 사용한 것을 본 연구의 대상에 맞게 수정ㆍ보완하여 사용하였다. 연구는 사전준비-사전검사-또래도우미 활동 적용-사후검사 순으로 이루어졌다. 수집된 자료는 SPSS for window 21.0을 이용하여 ttest, 공변량분석(ANCOVA)으로 통계처리 하였다. 본 연구의 결과는 다음과 같다. 첫째, 전반적인 장애학생 수용태도의 변화에 또래도우미활동 참여 자발성 유무에 따른 집단 간의 유의미한 차이는 나타나지 않았으나 또래도우미 참여 집단과 통제집단 간에는 유의미한 차이가 나타났다. 둘째, 하위영역별 장애학생 수용태도에서는 교제영역과 학습영역에서 또래도우미 활동 참여 자발성 유무에 따른 집단 간의 유의미한 차이는 나타나지 않았으나 또래도우미 참여집단과 통제집단 간에는 유의미한 차이가 나타났다. 그러나 생활영역에서는 각 집단 간의 유의미한 차이가 나타나지 않았다. 본 연구의 결과는 또래도우미 활동은 일반학생의 장애학생 수용태도에 긍정적 영향을 미치며 또래도우미 활동참여 자발성의 유무는 참여자의 선정기준에 고려되어야할 요소가 아님을 밝혔고 통합교육을 위해서는 학교의 모든 구성원이 함께 참여하고 노력하여야 함을 시사한다. The purpose of this study is to examine the effects of voluntary participation in peer supporter activities on the accommodate attitude of children with disability. The subjects of this study were a total of 48 students, 3 elementary school students with disabilities in Busan and 16 normal students in the three integrated classes that the above disabled students were included and they were divided into three groups such as experimental group 1, experimental group 2, and control group. To measure normal students’ accommodate attitude toward disabled students, the questionnaire of Ahn Seungsuk(2002) was modified to use and peer supporter activities that Jang Hyeyoung(2011) had used were corrected to use for this study. The research was made up of preparation-pretest-applying peer supporter activity-post test in order. The collected data were analyzed using the SPSS for window 21.0 program with t-test, ANCOVA. The findings of the study are as follows: First, there are no meaningful differences in the change of accommodate attitude of disabled students among groups according to whether they participate in peer supporter activities voluntarily or not, while there are significant differences between participation group in peer supporter activities and control group. Second, there are no significant differences in association area and learning area, subarea of disabled students’ accommodation attitudes, among groups according to whether they participate in peer supporter activities voluntarily or not, while there are significant differences between participation group in peer supporter activities and control group and no differences in living area among groups. The findings of the study show that peer supporter activities have positive effects on normal students’ accommodate attitude and whether they participate in peer supporter activities voluntarily or not should not be considered for selection standard. Also, all members of the school need to try and participate for the integrated education.

소비자사전지식과 유인대안의 위치가 유인효과에 미치는 영향에 관한 연구

손용석(Yong Seok Sohn),권한나(Han Na Kwon) 한국마케팅학회 2010 마케팅연구 Vol.25 No.3

본 연구는 소비자들이 제품에 대한 속성 및 기술에 대한 제품지식의 관심이 높아짐에 따라 소비자의 제품 지식수준을 분류하여 유인효과를 활용하기 위해 유인대안의 가장 적합한 위치를 찾아내는 데에 초점을 두고 있다. 소비자의 사전지식 정도와 유인대안의 위치에 따른 유인효과분석을 실시한 결과, 중간 정도의 지식을 가진 소비자에게 유인효과는 가장 효과적인 것으로 증명되었고, LA, RR 그리고 LR의 유인대안의 위치에 영향을 받는 것으로 나타났다. 반면에, 사전 지식이 높은 소비자는 유인대안이 RA와 RR의 위치에 있을 때 영향을 받고, 사전 지식이 낮은 소비자는 유인대안이 LA의 위치에 있을 때 영향을 받는 것으로 나타났다. 위 논문은 실증분석의 결과들이 보고되고 논의된다. We study the consumer judgement and choice under uncertainty such that consumers with limited knowledge face to choose their most preferred product among a set of given alternatives, specially when a decoy alternative, asymmetrically dominated or relatively inferior, is added to the set. We hypothesize that there would be positions of the decoy alternative fit to better attract consumers according to their prior knowledge levels on the product. That is, the attraction effect interacts with consumers` prior knowledge and various positions of the decoy alternative. We derived theoretical reasons of the attraction effect occurred in various positions of a decoy alternative. The attraction effect occurs at LA(Left Asymmetrical) and RA(Right Asymmetrical) due to the range and frequency effect, and it also occurs at RR(Right Relative) due to the compromise effect within the set. The attraction effect rather decreases at LR(Left Relative) in an opposite direction due to the substitution effect. We then attempted to provide proper justifications upon the reasons by segmenting the market into low-knowledge, moderate-knowledge and high-knowledge consumers. Consumers with low knowledge were found to see a brand via the attribute easy to evaluate like the price, and could be attracted with the addition of a decoy alternative at LA. On the other hand, consumers with high knowledge would be able to evaluate on quality attributes, and were supposed to be attracted with the addition of a decoy alternative at RA or possibly at RR where the quality is lower and where the price is same or a little higher than those of a target alternative, respectively. We think that consumer with high-knowledge were allowed to reach at the choice decision with the integrated evaluation on the price and quality attribute by the addition of a decoy alternative (Wedell 1993). Finally since consumers with moderate knowledge are yet to have thorough product category knowledge but may feel somewhat knowledgable, they are supposed to be involved in the product knowledge. Accordingly, the attraction effect appeared at LA, RR and LR, while it turned out to be strongest for consumers with moderate knowledge (Malaviya and Sivakumar 1998). Based upon the research performed, we could suggest promising positions of a decoy alternative to draw the attraction effect toward the target alternative, and derive several boundary conditions of the effect specially with respect to the levels of consumers` product knowledge. We also suggest possible applications of the attraction effect regarding new product launch, positioning strategy over the product life cycle, price cut, sales promotion and so on. Finally, the experimental design and its results are reported. Some possible avenues for the relevant behavioral decision along with the limitations of this study are also discussed.

전력계통 주파수응답 실적 기반의 국내 AGC 주파수 바이어스 설정치 산정에 관한 연구

강보람(Bo-Ram Kang),권한나(Han-Na Kwon),국경수(Kyung-Soo Kook) 대한전기학회 2015 전기학회논문지 Vol.64 No.7

This paper presents Frequency Bias setting for the adequate AGC(Automatic Generator Control) operation based on the frequency response of power system in Korea. AGC frequency control recovers the frequency up to 60Hz following a primary control when the frequency suddenly drops due to a fault in power system. AGC can compensate an appropriate amount of generation by calculating ACE(Are Control Error) from the frequency deviation with the AGC frequency bias set from the actual frequency response in power systems. An appropriateness of the proposed AGC bias setting is verified through case studies employing the simulation model.
