Comparing Advertising Attributes on Sexual Appeal : A Study of U.S. and Korea

Park, JaeKwan 慶州大學校 2005 論文集 Vol.18 No.1

Advertisers in a global marketing context must understand the influence of cultureto design the most effective promotion for a target population. This study extends researchin cross-cultural advertising by examining differences between the United States and Korea relative to sex appeal, model race and informational copy in print advertising. Conjoint analysis is used to evaluate both the influence of these attributes on preferences as well as their relative importance by culture. Results indicate nudity has the strongest effect followed by model race and information level. Suggestions are made of optimum advertising attribute levels based on ideal point conjoint results.

최근 세계 각국은 기후변화 대응을 위한 온실가스 감축과 더불어 미래 신성장 동력 확보의 일환으로 재생에너지 개발과 보급 확대를 위한 정책적 노력을 집중하고 있으며, 이에 따라 동 정책들의 효과성을 분석하기 위한 많은 학문적 연구가 진행되었다. 다만, 기존의 많은 연구들은 패널자료를 활용한 계량적 분석에서 정책들 간 상호작용효과와 정책의 의존성 문제에 대한 논의 그리고 정책들의 장ㆍ단기적 효과에 대한 분석이 다소 부족하였다. 이에 본 연구는 OECD 25개국에서 시행 중인 정책수단을 핵심변수로 활용하되 유사한 정책들의 통합변수 구성 등을 통해 보다 효과적인 정책 분석을 시도하였고 동시에 각 국가에서 도입되고 있는 정책의 성과 등을 파악하였다. 분석 결과 첫째, 조세정책은 단기적으로는 재생에너지 발전과 확대에 강력하게 기여하고 있으나 장기적으로는 효과가 없는 것으로 나타났다. 둘째, 발전차액지원제도 등 가격기반 정책과 투자ㆍ보조금정책은 단기적으로는 그 효과가 미미하나 장기적으로는 매우 긍정적인 영향을 미치는 것으로 분석되었다. 셋째, 공급의무할당제도 등 수량기반 정책은 재생에너지 발전과 보급 확대에 유의미한 영향을 미치지 못하는 것으로 분석되었다. 이러한 연구 결과는 실증적 분석과 더불어 각국에서 운영하고 있는 정책의 경험적 분석을 토대로 정책의 효과성을 제시한 것으로 이론적 가치를 지니며, 보다 실효적인 정책 방향을 제시하는 데 기여할 수 있다. In recent times, countries around the world have been concentrating their policy resources on the development and wider deployment of renewable energy as part of efforts to reduce greenhouse gas emissions to address climate change and to secure new growth engines for the future. Accordingly, a number of studies have been conducted thus far to analyze the effectiveness of related policies. However, existing studies leave much room for improvement as they, in many cases, lack analysis on the effects of interactions among different policies, interdependence of those policies and short- and long-term effects of those policies while examining panel data analysis. For this reason, this study aimed at more effective policy analysis by using policy measures being taken by 25 OECD member countries as key variables and by making similar policies as composit policy variables, respectively. At the same time, it also tried to assess the implementation of policies introduced by countries in question. The findings of this study include: First, Tax related policies was found to be a strong contributor to the development and wider use of renewable energy in the short term, but not effective in the long term; Second, price-based policies including Feed in Tariff (FIT) programs as well as investment and subsidy schemes were proved to be not so much effective in the short term, but to have very positive impact in the long term; and Third, it was found that quantity-based policies including Renewable Portfolio Standards (RPS) did not have meaningful impact on the development and dissemination of renewable energy. The results of this study have demonstrated the effectiveness of policies undertaken by countries around the world through practical and empirical analysis, and it is also expected to provide adequate directions for policy-makers in formulating more effective renewable energy policy.

Measuring Psychological Support for the Unemployed: The Case of Kakao NEET Project

( Jaekwan Jeong ),( Kahui Park ),( Yaewon Hyun ),( Daewon Kim ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.4

This paper attempts to investigate Korean youth Not in Education, Employment and Training (NEET) and how daily activities and community participation may influence their positive emotions and job search desire. First, we conducted a focus group interview with 16 NEETs who participated in the Kakao NEET Company project. The project allowed participants to experience employment by founding a virtual company in which each participant selected a daily activity to perform as part of the company’s operations. Second, the interview responses were categorized and assigned emotional values using the card sorting technique and multi-dimensional analysis (MDS). A total of 11 emotional values were derived through this process. Finally, a social network analysis was conducted in order to measure the density of relations among the emotional values. Results suggest that immersion, confidence, belongingness were the three highest values evaluated by participants. Furthermore, network diagrams imply that the stronger participants perceived social support and belongingness with others, the stronger their responsibility grew, further leading them to establish steady goals. In particular, the high eigenvector score for “desire for job” suggests that emotional values are sequentially connected to the immersion-social support-responsibility-goal-job desire. This sequence suggests that digital services that are developed with the aim to enhance social values such as the Kakao NEET Project may engender motivation and confidence in youth NEETs. The overall results suggest that a systematic approach to policymaking should be considered in order to provide fundamental solutions and expand opportunities for social participation and emotional comfort, as social isolation due to low self-esteem has been reported as one of the reasons for NEETs’ failure in the labor market.

조향률에 기반한 자동차의 회전 궤적 모델링

김재관(Jaekwan Kim),배일(Il Bae),김시호(Shiho Kim) 한국자동차공학회 2012 한국자동차공학회 학술대회 및 전시회 Vol.2012 No.11

We proposed a steering control method for an autonomous vehicle by controlling the steering rate instead of the steering angle. The lateral dynamic model of this work is based on the bicycle model of the vehicle. The proposed kinetic model is implemented in LabVIEW Design and Simulation module. The trajectory of vehicle obtained from simulations shows predicted Clothoid spirals when a steering rate input changes from driving straight lane to circular road. The proposed model was verified by LabVIEW simulations of lane change test. The proposed steering model can be applied to a real 4 wheel-car eventhough its based on bicycle model assumption, because difference between left and right wheel angle is easliy considered by Ackerman turning geometry. The proposed method will be applied to trajectory planing and steering controller algorithm for development of unmanned autonomous vehicles.

전동 조향 시스템을 위한 횡 외란 관측기를 갖는 견인 제어기의 설계

The driver plans a path by preview and controls the lateral deviation of vehicle from the planned path via the<br/> steering wheel. However, the traveling vehicle is always affected by unknown lateral disturbances such as the<br/> gravitational force from lateral slope and the aerodynamics force from crosswind. This paper describes a design<br/> method of an observer to estimate the unknown lateral disturbances and an approach to realize a robust lateral<br/> control system that can stabilize lateral vehicle dynamics under such situations. Moreover, it is expected that the<br/> steering torque control of the pinion-type EPS(Electric Power Steering) in this paper provides some degree of<br/> freedom for allowing the driver to steer even during the control operation, thus offering the potential for the provision<br/> of a steering assist mechanism.

조향감을 고려한 전동 조향시스템의 견인 횡제어

이재관(Jaekwan Lee) 한국자동차공학회 2003 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-

This paper presents the dynamical modeling and control of a vehicle affected by unknown lateral disturbances such as the gravitational force from lateral slope and the aerodynamics force from crosswind. In this paper, the proposed control method is not designed with steering angle but steering torque of the pinion-type Electric Power<br/> Steering on the basis of H_2 control theory. Moreover, it is expected that since the dynamics of steering input shaft (i.e., handle dynamics) is considered on control object, the controller in this paper can provide some degree of freedom for allowing the driver to steer even during the control operation. The performance and robustness is analyzed by computer simulation.<br/>
