This study investigates the differences in advertisement attitude, brand attitude, and purchase intention based on advertising model and consumer product involvement. A total of 100 respondents in high involvement and 100 respondents in low involvement categories were exposed to the advertisements of a cosmetic brand using 4 different model types: celebrity endorser, expertise endorser, ordinary person as an endorser, and no endorser. The experiment was planned as $2{\times}4$ types including high/low involvement and 4 different model types (25 respondents each). After looking at an advertisement for 1 minute, respondents were asked to answer a survey measuring advertisement attitude, brand attitude, and purchase intension. The results of this study showed that 6 hypotheses were supported and there was a significant difference between the high involvement and low involvement group depending on the advertising models used as well as the advertisement that influence advertisement attitude, brand attitude, and purchase intension. High involvement consumers showed the most favorable advertisement attitude on an advertisement with an expertise endorser, but low involvement consumers showed the most favorable advertisement attitude on an advertisement with a celebrity endorser. High involvement consumers showed the most favorable brand attitude on an advertisement with an expertise endorser whereas low involvement consumers showed the most favorable brand attitude on an advertisement with a celebrity endorser. High involvement consumers showed the highest purchase intention on an advertisement with an expertise endorser whereas low involvement consumers showed no difference in purchase intention depending on advertisement models. This study shows that marketers should differentiate advertising strategies based on consumer involvement.

Purpose: The study examined the effects of preoperative patient controlled analgesia (PCA) education on postoperative pain, knowledge of PCA, and attitude toward pain medication. Methods: The participants were patients who underwent surgery in H University Hospital,and were assigned to PCA group (experiment group, n=30) or the control group (n=30). Results: Knowledge of PCA and positive attitude toward pain medication were higher in the experiment group than in the control group. Postoperative pain scores in the experiment group were significantly lower than those in the control group at 48 and 72 hr after surgery, but there was no significant difference at 24 hr after surgery. The experiment group had more positive attitudes on the medication than the control group. Conclusions: Preoperative PCA education could be an effective nursing intervention for pain management of patients after surgery.

UAV는 임무 수행을 위한 INS 장비와 광학 장비를 갖추고 있다. 이 논문에서는 UAV를 위한 알고리즘으로 칼만 필터와 광류를 이용하는 영상기반 자세추정 알고리즘을 제안한다. 광류는 UAV에 장착된 카메라의 영상으로부터 획득하며 UAV의 자세는 광류를 통해 측정된다. 이 논문에서 UAV 자세의 추정과 낮은 신뢰성을 보완하기위해 칼만 필터를 사용한다. 그리고 실험을 통해 알고리즘을 검증하였다. Rate table과 실제 비행영상을 이용하여 실험 하였으며, 본 논문에서 UAV의 자세 추정 알고리즘 검증 결과를 보였다. Rate table 실험에서 오차는 2도 이내였으며, AHRS를 통해 측정한 결과와 비슷한 경향을 보인다. 그러나 실제 비행 영상 실험에서 최대 Yaw 오차는 21도였으며, 최대 Pitch 오차는 7.8도로 나타났다.

대학에서의 여가교육은 여가 레크리에이션 이론 및 실기강의, 교양체육과 같은 각종 여가활동 실기강의를 통해 직접적인 교육이 이루어지고 있다. 기존의 연구에서는 교양체육과 같은 실기과목 강의가 수강생들의 여가태도에 긍정적인 영향을 미치는 것으로 보고 있으나 이론강의에 대한 효과는 검증되지 못하고 있다. 이에 본 연구는 대학에서 이루어지고 있는 여가교육 이론 강의가 수강생들의 여가태도에 어떠한 영향을 미치고 있는지에 대한 효과를 검증하고자 하였다. 연구목적을 달성하기 위하여 실험연구방법을 활용하였다. 본 연구자는 피험자로 충청북도 S대학교의 여가 레크리에이션 교양 이론강의를 수강하는 학생들 167명을 선정하였다. 이들을 대상으로 하여 15주 동안 매주 2시간씩 강의를 진행하여 여가태도의 변화를 확인하였다. 자료 수집을 위해 Ragheb과 Beard[22]의 LAS척도를 활용하였으며, 첫 강의와 마지막 강의를 시작하면서 설문지를 배포 후 회수하였다. 수집된 자료는 통계프로그램인 SPSS 12.0을 활용하여 대응표본 t-검정을 실시하였다. 통계분석 결과 여가교육 이론 강의는 여가태도의 4개 하위영역 즉, 인지적, 정서적, 행동 의도적, 그리고 행동적 여가태도 모두에서 높은 수준의 긍정적인 효과가 나타났다. 또한 수강생들의 성별과 학년에 따라 여가태도에 미치는 효과가 다르게 나타났다.

This paper presents the attitude algorithm using Fuzzy technique to mix gyro information with accelerometer. The attitude angle calculated by the low-cost gyros only increases its error with time rapidly because of the integration process of the algorithm and large sensor error. It is known that the accelerometer output includes the attitude information of a vehicle and its information is more effective during low dynamic maneuver. Therefore it is needed to combine two information appropriately for obtaining the attitude information from low-cost MEMS inertial sensors. Because Fuzzy logic is very effective to make a decision of maneuvering state, it is applied to the mixed algorithm. It is shown by experiment ...

Helicopter offer the signigicant advantage over traditional air vehicles, in that the provide extended maneuverability, such as vertical climb, hovering, longitudinal and lateral flight, hovering turns and bank turns. But helicopter have the strong cross couplings and nonlinearities for each lateral, longitudinal and rotational motion mutually. However, it is possible to ignore this couplings for the hovering condition, so using this properties we can control the attitude of helicopter. That is, by implementing the dynamic of each rotational axis(roll, pitch, yaw) of independent mutually, 3-DOF(degree of Freedom) attitude control for the helicopter is possible. In this paper, we identify decoupled input-coutput relations of each three rotational axis about the helicopter mounted on the 3-DOF gimbal by experiment, and on these basis implement 3-DOF attitude controller using the PID control method.

Purpose: To examine the effect of a smoking prevention program on changing the knowledge and attitude toward smoking behavior of male middle school students. Method: A total of 69 male middle school students participated in this study. Each of them was assigned to either smoking prevention program (n=35) or to a control group (n=34). The intervention for the experiment group was developed by the investigator. The questionnaires for assessing knowledge and attitude were created by modifying scaled employed in previous studies. Result: 1) The experimental group with smoking prevention program showed higher scores in knowledge for smoking harmfulness in comparison with the control group (F=18.782, p=.000). 2) The experimental group with the smoking prevention program showed lower scores in attitude toward smoking behavior in comparison with the control group (F=17.483. p=.000). Conclusion: The results showed that the smoking prevention program was effective on improving knowledge and attitude toward smoking behavior in male middle school students. More studies on development of comprehensive smoking prevention programs for adolescents need to be conducted in the future.

본 논문에서는 스테레오 카메라 시스템을 이용하여 헬멧의 자세 및 위치를 추정하는 알고리즘을 제안한다. 본 논문에서 구축한 시스템은 두 대의 CCD카메라와 헬멧 그리고 적외선 LED, 영상편집 보드로 구성된다. 이 중 15개의 적외선 LED는 헬멧에 서로 다른 길이로 삼각형 패턴으로 고정되어, 헬멧의 자세 및 위치를 결정하기 위한 특징점이 된다. 본 논문에서 제안한 알고리즘은 특징점 추출, 투영 재구성, 모델 인덱싱 과정으로 구성되며, 단위 쿼터니언(UQ, Unit Quaternion)을 이용하여 자세 및 위치를 추정한다. UQ를 이용하여 회전행렬를 구하면, 회전 행렬이 유니터리 행렬(Unitary Matrix)이 되는 것을 보장할 수 있다. 제안된 알고리즘은 시뮬레이션과 실제 실험 데이터를 이용하여 그 성능을 검증하였다.

This study investigates the effects of a two-sided message on product attitude and purchase intention by using a message structure variable, such as attribute importance in the context of online consumer reviews (OCRs). Study 1 explains the previous inconsistent results of a two-side message by comparing a one-side message and a two-side message by using the attribute importance in negative reviews. Study 2 determines the reasons for the inconsistent results of a refutational two-sided message research by using the attribute importance in negative reviews and website trust. Two experiments are designed to test our hypotheses. The first experiment is a $2{\times}2$ factorial design with 84 participants. The second experiment uses a $2{\times}2{\times}2$ factorial design with 196 participants. In study 1, two-sided OCRs are more credible than one-sided OCRs, and two-sided OCRs that use low important attributes are more effective in making favorable product attitude/purchase intention. In study 2, refutational two-sided OCRs that use high attribute importance render positive effects on product attitudes in trustworthy websites. However, the refutation could negatively affect product attitude/purchase intention in low trustworthy websites.
