Purpose: This study was done to identify nursing interventions clinically applicable to relieve displeasure and anxiety of patients having an operation in which loud noise was unavoidable. Methods: Participants were 34 patients scheduled to have a total knee replacement. They were assigned to either the control (17 patients) or experimental (17 patients) group. Data were collected from September to November 2010. The instruments used for the survey included noise-control earplugs, a noise level meter (TES-1358) and a structured scale measuring degree of noise perception, displeasure and anxiety. Data were analyzed using frequency, percentage, standard deviation, $x^2$-test, and t-test with the SPSS WIN 18.0 program. Results: Hypothesis 1: 'The displeasure levels of the experimental group of patients wearing earplugs will be lower than the control group patients without earplugs' was accepted (t=-20.769, p<.001). Hypothesis 2: 'The anxiety levels of the experimental group of patients wearing earplugs will be lower than the control group patients without earplugs' was accepted (t=-6.298, p<.001). Conclusion: Based on these findings, the wearing of earplugs for patients having a surgical operation with loud noises is recommended as an effective nursing intervention to relieve patient displeasure and anxiety during their surgical operations.

Objective: The aim of this study is to investigate the gender-differences in vibrotactile responses(sensitivity and displeasure) of residual forearm simulated by vibration stimulation in upper limb(trans-radial) amputees. Background: Several studies have reported that vibration stimulation using the haptic vibrator is one the most effective methods for delivering sensation to an amputees. However, few studies have reported the perception to haptic vibratory stimulus, particularly sensitivity and displeasure. Method: We set up a custom-made vibration stimulation system that included 6 actuators(3 medial parts and 3 lateral parts) and a graphical user interface(GUI)-based acquisition system to investigate changes in residual somatosensory sensibility and displeasure in the forearm of upper limb(trans-radial) amputees. Vibration actuators were attached at the 25%-point on the proximal forearm. Stimulation with 32Hz, 64Hz, or 149Hz of frequency was used for the sensitivity tests and with 32~257Hz of frequency was used for the discomfort experiments. The subjective responses were evaluated on a 10 point scale. Results: The results showed that vibrotactile sensory perception in male amputees were higher than that in female amputees. In male amputees, the response at lateral area of forearm was the most sensitive than medial area; but, female amputees showed similar sensitive areas. Subjects did not experience any discomfort during vibrotactile stimuli. Conclusion: Vibrotactile response in the amputees was dependent on gender as well as area stimulated by vibration. Application: The results might contribute to develop the vibrotactile feedback system for the amputees.

Research involving discomfort or pain related to haptic vibratory stimulation the for prosthesis users of myoelectrical hand is very lacking. Our objective of this study was to evaluate the displeasure and sensitivity of areas in forearm using vibration stimulation system between upper limb amputees and non-amputees. Twenty transradial amputees and forty non-amputees (20 youth, 20 elderly) were involved. We set up custom-made vibration stimulation system including eight actuators (4 medial parts and 4 lateral parts) and GUI-based acquisition system, to investigate changes of residual somatosensory sensibility and displeasure at proximal 25% of forearm. Eight vibration actuators were attached to the circumference of proximal 25% point of forearm at regular intervals. Sensitivity tests were used to stimulate the 120Hz and discomfort experiment was used to 37 ~ 223Hz. The subjective responses were evaluated by 10 point scale. The results showed that both groups were similar in sensitive areas. Response at around of radius was most sensitive than other areas in all subjects. Elderly group do not appear discomfort of vibrotactile; however, youth group and amputee presented discomfort of vibrotactile. Prosthesis with a vibrotactile feedback system should be developed considering the sensitivity. Furthermore, Future studies should investigate the scope of application of that principle.

The purpose of this study was to extract emotional dimensions from Korean adjectives relating to apartment noise. Noise-related 296 Korean adjectives were extracted from a dictionary and three evaluators selected 96 adjectives from those by removing very similar ones in meaning. Two types of 96 7-point scales were conducted to college students for evaluation, whether each adjective describes apartment noise appropriately. From this evaluation, 28 adjectives having above 4.5 points were selected. Again, 8 different types of 7-point scales on 378 adjective pairs(28 x 27/2) were administrated to separate college students to evaluate the degree of similarity between 28 adjectives. Based upon this evaluation, 14 adjectives were finally selected and scores on similarity sere analyzed through two different statistical analyses (Multi-dimensional scale and Cluster analysis). The results showed that three dimensions (displeasure, sensitivity and perceived loudness) exist in peoples' emotional response state to apartment noise. The previous studies have treated annoyance and sensitivity as separate measures to noise. However, this study showed that these two factors were on the same emotional dimension labeled as 'sensitivity' In addition, new dimension, labeled as 'displeasure', was found.

This study attempts to understand how the perception of service quality as well as shopping motives influence on the emotional responses in store shopping, and to examine how these relevant variables influence on the store satisfaction. The 463 questionnaires were collected from the purchasers in department stores, fashion specialty stores, and national brand franchise stores. The results of this study are as fellows: 1. In regard to shopping motives, two dimensions of product motive and experiential motive were identified, explaining 47.39% of shopping motives. 2. In regard to emotional response, two dimensions of pleasure emotion and displeasure emotion were identified, explaining 65.95% of emotional responses. 3. Shopping motives led to the store satisfaction after the perception of service quality and then the experience of pleasure emotion. These related variables explained 60% of the store satisfaction. 4. The consumers of fashion specialty store showed the highest product motive, whereas the consumers of department stores showed the highest displeasure emotion in the store. As the results showed, customers' shopping motives influence their perception of service quality and pleasure emotion. Therefore, in order to stimulate shopping motives, the store environment that can give customers pleasure and opportunity to pursue various experiences should be provided. As the service quality is a very important variable that leads pleasure emotion in the store, sales persons should be trained to satisfy customers.

본 논문에서는 애니메이션 캐릭터의 표정 연출의 효율성을 높이기 위해 정서 상태의 변화에 따라 다양하고 주어진 상황에 부합하는 표정을 쉽게 구현할 수 있는 표정생성 프로그램을 제안하고자 한다. 이를 위해 우선, Russell의 내적 정서 상태의 차원 모형을 근거로 쾌-불쾌, 각성-비각성의 내적 정서 상태 정보를 포함한 9가지 표정을 정의하였다. 그리고 각각의 표정에 대해 본 연구에서 제안한 표정생성 프로그램을 이용하여 두 차원의 중앙에 위치하는 무표정 자극을 8가지의 가능한 표정 변화 방향으로 이동시킴으로써 정서 차원에서의 미묘한 위치 변화에 따라서도 다양한 표정 생성이 구현될 수 있음을 확인하였다. 향후 이러한 프로그램은 복잡한 정서를 가진 표정을 쉽고 다양하게 구현할 수 있는 표정 자동생성 시스템 설계의 기초적 프로그램으로 활용될 수 있을 것이다.
