Objective：This study was designed to evaluate effects of methylphenidate(MPH) on event-related potentials(ERP) and continuous performance test(CPT) in attention-deficit hyperactivity disorder (ADHD) and to see the correlation between changes in ERP and changes in performance. Method：ERP and CPT were used to examine the acute effects of MPH(0.5mg/kg) in eleven ADHD boys(89-103 months old). Results：1) After MPH administration, P3 latency to nontarget stimuli at Fz was significantly decreased (p<0.01) and P2 amplitudes to target stimuli at Pz and at Oz and P3 amplitude to target stimuli at Cz were significantly increased(p<0.05). 2) Commission error and omission error in the CPT-X and commission error in the CPT-AX were decreased(p<0.01), and hits and perceptual sensitivity(d') in the CPT-X and d′ in the CPT-AX were increased(p<0.01). 3) The change of P3 latency to nontarget stimuli at Fz and the change of d′ in the CPT-X were negatively correlated(p<0.05), and the change of P2 amplitude to target stimuli at Pz and d′ in the CPT-AX were positively correlated(p<0.05). Conclusion：MPH improves change orienting reaction, the delivery of task relevant information, accuracy and perceptual sensitivity in ADHD. And the increase of ability to discriminate targets from non-targets reflects reduced evaluation time in large memory component task and enhanced change orienting reaction in simple task.

자연적인 서식지에서 토끼는 번번히 육식 동물의 먹이가 된다. 이들의 일차적이고 우선적인 생존 반응은 발견을 피하기 위한 노력으로 조용히 있는 것이다. 토끼는 폭발적인 속도를 빠르게 낼 수 있고 짧은 거리에서 즉시 방향을 바꿀 수 있도록 가벼운 뼈, 작은 앞다리, 강력하고 잘 발달된 뒷다리를 가졌을 뿐만 아니라, 예민한 청각과 즉각적인 후각을 발달시킴으로써 'fight or flight(적자생존)'로 적응해왔다. 이런 생존 반응은 욕구가 없어진 것으로 나타나는 대부분의 집토끼에도 여전히 존재하지만, 이런 토끼들은 장애에 대해 반응이 불완전하고 변화에 쉽게 스트레스를 받는다. 스트레스를 받은 동물은 일차적으로 anorexia와 용변의 빈도와 일관성에 변화를 유발하는 건강, 생식, 행동적인 문제에 더욱 민감하다.

The feeding sounds of three fishes, Lateolabrax japonicus, stephanolepis cirrhifer and Fugu vermicularis were recorded in the tank, and the frequency and the sound pressure level were analyzed. The recorded sounds were emitted again into the tank and the response of fishes were observed. The results obtained are summarized as follows: 1) The frequency and the sound pressure level of the feeding sound of Lateolabrax japonicus, Stephanolepis cirrhifer, and Fugu vermicularis are 80~350 Hz and 250~500 Hz, and 101~103 dB, 106~115 dB and 102~112dB. 2) It was most effective to increase the sound pressure level as much as dB that make the fishes respond positive reaction to the feeding sound. 3) Lateolabrax japonicus and stephanolepis cirrhifer showed positive response and Fugu vermicularis showed little to the emitted feeding sound. 4) The fishes showed positive response to the sound until 5 minutes and then showed negative response, as the sound emitting succeed 10 minutes.

본 연구는, 그 동안 간과되어 왔던 의류 상품의 판촉에 초점을 맞추어, 판촉의 여러 방법 별 소비자들의 반응 정도를 알아보고, 그 반응 경향이 소비자의 인구통계적 특성, 판촉에 대한 태도, 의복 쇼핑 성향, 기타 의복 구매 행동과 연관성을 가지는지를 규명함을 목적으로 한다. 수도권 거주 여성 444명을 대상으로 수집한 자료를 이용해 분석이 이루어졌다. 실증적 연구를 통해 다음과 같은 결과를 얻었다. 첫째, 판촉의 각 방법에 대한 소비자들의 반응 정도는 가격 할인이 가장 높았고 그 다음은 디스플레이, 쿠폰, 사은품, 백화점 패션쇼, 경품의 순서로 나타났다. 가격 할인, 디스플레이, 사은품, 쿠폰, 백화점 패션쇼 등 5가지 판촉 방법에 대한 소비자 반응 정도를 기준으로 군집분석한 결과 판촉에 대한 반응 유형에 있어 차이를 보이는 5개 집단을 규명할 수 있었다. 각 집단의 인구통계적 특성들 중에서는 소비자 자신의 학력과 자녀의 연령만이 집단간에 유의한 차이를 보였으며, 각 집단의 판촉 태도는 집단 간에 유의한 차이를 보였다. 둘째, 각 집단은 의복 쇼핑 성향 및 의복 구매 관련 정보원 이용에서 차이를 보였다. 결론에서는, 실증적 연구의 결과 판촉에 대한 소비자 반응 유형별로 인구통계적 특성, 판촉 태도, 의복 쇼핑 성향, 기타 의복 구매 행동에 차이가 있음을 알 수 있었으므로 의류 상품의 판촉 전략 수립시 표적 집단의 특성에 따라 판촉 방법 선택이나 판촉 정보 전달 경로 등을 조절하는 것이 필요함을 제언하였다. 예를 들어, 신중/경제적 쇼핑 성향을 가지며 판촉에 대한 태도가 호의적인 소비자들에 대해서는 다양한 정보 전달 경로를 통해 가격 할인이나 쿠폰을 제공하는 것이 좋은 판촉 방법이 될 것이며, 쾌락/유행 지향적이고 상표/품질을 중시하는 소비자들에 대해서는 잡지, 인적 정보, 카탈로그 등을 정보 전달 경로로 하여 디스플레이나 패션쇼를 통해 판매 촉진을 할 수 있을 것이다.0.10 $h^{-1}$과 0.09$h^{-1}$h-1이었고, 반감기는 각각 6.93 및 7.70시간으로 측정되었다. 각각의 농도에서 12시간 및 8시간 이후에는 g당 0.19$\mu\textrm{g}$ 및 0.18$\mu\textrm{g}$이하로 떨어짐을 알 수 있었다. Phosphamidon과 profenofos의 급성어독성은 profenofos가 높았고, BCF profenofos가 phosphamidon보다 약 100배 정도 높게 나타났으며, 배설속도는 phosphamidon이 profenofos보다 약 2배 정도 빨랐다.

This study identified the relationship between adolescents' alienation and stress responses, and examined the mediating model of smart media addiction moderated by behavioral activation system (BAS) on alienation and stress responses. Participants were 361 male and female students in middle and high schools located at Seoul metropolitan area. PROCESS Macro 3.5 Model 7 was used for analysis of the moderating mediating effect. Results revealed that adolescents' alienation and BAS were positively correlated with smart media addiction and stress responses, while smart media addiction was positively correlated with stress responses. In a moderated mediating model for stress responses, there was significant interaction effect of alienation and BAS; conditionally indirect effect of alienation was not significant in groups with very low BAS. These findings suggest that adolescents who feel alienation are more likely to experience stress responses by overindulging themselves in using smart media. The moderating effect suggests that this effect is stronger with higher levels of BAS.

The common features of the behavioral inhibition and the action monitoring that are considered as one of the executive functions were investigated using event-related brain potentials (ERPs) and source localization analysis. The electrophysiological correlates of behavioral inhibition and action monitoring ate analyzed when the subjects performed the Go/NoGo task. Two ERP components of behavioral inhibition termed as N200 and P300 in NoGo condition were differ from those of Go condition, that is the amplitudes of NoGo N200 and P300 are largest on the fronto-central region, which may reflect the inhibitory control of frontal lobe required in NoGo condition. The error-related negativity (ERN) observed on the fronto-central region when the subjects committed error was much larger in amplitude and faster in latency than those of the correct-related negativity (CRN), which may indicate that the signal of action monitoring is much more required for the error response. The correlation analysis for the ERP components of behavioral inhibition and action monitoring revealed the significant negative correlation among the latencies of NoGo N200 and P300 and the amplitude of ERN, which may reflects that the faster subjects inhibit response, the more monitor their own action. The close relationship between behavioral inhibition and action monitoring was also supported by the results of source localization analysis, which showed the common neural sources of NoGo N200 and ERN was anterior cingulate cortex.

The current study examined the effects of the voters' perception of television news coverage of election poll results on their political participation intention. 700 voters participated in a telephone interview three weeks before the 2012 Korean presidential election. A structural equation modeling with the nationally representative sample was performed. The findings indicate the respondents were more likely to evaluate television news coverage of election poll results negatively when the news coverage presented that the candidate they supported was behind in the race, and the negative evaluation was linked to a greater third-person perception. The third-person perception, in turn, had an indirect effect on political participation intention through negative emotional responses. The results imply that voters' political position influences their perception of the television news coverage of election poll results, and this perception can have indirect effects on political participation.

This study was designed by paying attention to the negative aspects of the performing arts service. As interest in performing arts increases, various studies on services are being conducted in the performing arts field as well. However, although research on the positive side of performing arts services is steadily increasing, research on the negative side is insufficient. In this study, the limitations of existing studies were supplemented and the study was conducted by applying the Stimulus-Organism-Response (S-O-R) model for empirical research. The effect of failure of performing arts service as a stimulus variable on the response to complaint behavior through negative emotion as an organism was verified. As a result of the analysis, it was found that among the factors of failure in performing arts services, performance works and personal services had a significant influence on negative emotions. In addition, the influence of negative emotions on public and private complaints was confirmed. Lastly, this study will have academic significance in that it analyzed consumers by converting the factors of service failure of performing arts into variables.

The purpose of this study was to investigate the appearance orientation and clothing and cosmetics purchasing behaviors according to media contact responses. The subjects were 445 female university students in Daejeon and Chungnam province. The measuring instruments was a questionnaire with media contact responses, appearance orientation, clothing and cosmetics purchasing behavior, and subjects' demographic characteristics. The data were analyzed by Cronbach's ${\alpha}$, frequency analysis, ${\chi}^2$ test, ANOVA, Duncan's multiple range test, and regression analysis using SPSS program. The results were as follows. First, female university students had very positive response and attitude on entertainers' appearance, style and products showed by media. Second, media contact response had a significant effect on appearance orientation. The group with a high level of media contact response showed higher appearance orientation than the groups with mediate and low level of media contact response. Third, media contact response had meaningful effects on clothing and cosmetics purchasing behaviors. The group with a high level of media contact response showed higher shopping frequency, purchasing frequency, and more spending on clothing and cosmetics than other groups.
