Four experiments were conducted to examine whether maintaining the same conceptual context across study and test would affect performance on a perceptual implicit memory task. The sense-specific theory of priming (Lewandowsky et al., 1989) predicts greater priming from a match in conceptual context across study and test compared with a condition in which the conceptual context is mismatched, whereas the transfer-appropriate-processing view (e.g., Blaxton, 1989) predicts no difference. In experiment 1 and 2, little or no effect of varying context was observed on a implicit task. In experiment 3 and 4, a process-dissociation procedure (proposed by Jacoby, 1991) was used to separate automatic influences from consciously controlled influence in implicit memory, which was measured by Korean word completion task. The results showed that conceptual context effect was observed in consciously controlled parts of implicit memory. These results suggest that only consciously controlled processing parts of implicit memory is sensitive to conceptual context.

Any enterprises cannot be free from service failure because of service attribute. Thus, the effort to recover from service failure properly has an important meaning. This study emphasizes on the need of effort of service recovery and distinguishes the operant situation of service failure into severity and controllability. At this moment in time, this study wants to verify the role of the effect of justice awareness on trust and satisfaction and adjustment role of employees' authenticity. An object of his study was 206 people who complained about service and this study analyzed their questionnaires by using SPSS, AMOS. To sum up, First, this study result shows that the seriousness of service failure has a negative effect on justice and only controllability has a negative effect on justice. Second, this study result shows that justice awareness has a positive effect on trust and satisfaction and that recovered trust has a positive effect on satisfaction. Third, authenticity has regulation effect on the structural relationship of severity, controllability, trust and satisfaction. Based on such result, this study presented suggestive point and suggested future study.

Only service organizations providing service quality above customers' anticipations have survived and developed in hyper competitive environment. These organizations are more dependent on their customer-contact service employees than those providing tangible products, because of the characteristics of service, intangibility, inseparability, heterogeneity, and perishability. But few researches focused on the efficient managements or controls of service organizations in this context. Therefore, author aimed at understanding of the determinants of service organizations' control system(i.e., characteristics of service), service employees' reaction on control types(i.e., service employees' role stress), and their performance(perceived service quality by customers). First the concepts of service quality and control systems are described. Specially, author explained the differences between service quality and service satisfaction or service attitude, and the control system types and their fundamental ideologies. Second, some propositions are provided according to integrated framework developed in this paper: (1)control types according to the characteristics of service, (2)influences of control systems on employees' reactions and (3)perceives service quality by the customers, and (4)relationships between the reactions and the service quality. This paper concludes with a summary, a discussion of theoretical and managerial implications, and several suggestions for future directions.

IThe perception of sub-second duration through the visual sensory system is affected by non-temporal characteristics (factors other than the duration of the stimulus). However, studies have shown that if distance information is abundant and size constancy maintained, the duration of the target is constantly perceived. The current study examined the relationship between size and time perception constancy in a three-dimensional environment with limited distance information. A device was constructed to limit the participants' bilateral and monocular cues. This prevented participants from maintaining size constancy, resulting in size illusions that could not accurately perceive physical size. In Experiment 1, the size of the physical stimulus of reference and test stimuli were the same at all viewing distances. The results suggest that, despite the same physical size, stimuli with close observations were perceived to be greater and lasted longer. In Experiment 2, the retinal size of the reference stimuli and test stimuli was controlled equally at all viewing distances. As a result, although the physical size of the stimuli increased as the observation increased, the perceived size of all the stimuli was the same. Therefore, the duration of the target was constantly perceived at all viewing distances. The results of this study demonstrate that even when distance information is limited, time perception is affected by the perceived size of the object. It also suggests that when rich distance information exists, the duration of the object can be constantly perceived even if the observation distance varies.

The purpose of this study was to analyze the effects of using the geometric manipulative for the development of spatial sense and thus to find out a better mathematics teaching and learning method that could help develop students' spatial senses. The two fifth grade classes were randomly chosen as an experimental group (31 students) and a control group (32 students), respectively. This study implemented nonequivalent control group pretest-posttest design of quasi-experimental design. The test instrument used in this study was a spatial sense test. The pretest and posttest were implemented with the same instrument. In addition, their classes were observed and videotaped, and the data and their study activities were analyzed. In conclusion, first, the geometric manipulative-aided activities contributes to developing students' spatial senses and their two sub-factors involves perceptual consistency and perception of spatial relationship. Second, the activities of grasping the components of solid figures, sketches and development figures by using the geometric manipulative contribute to boost students' perceptual consistencies and their perceptions of spatial relationship.

The purpose of this study is to identify the factors affecting the adaptation, Self-esteem and self-control of college students to smart addiction. We surveyed 380 university students in Gwangju area. Data were analyzed by t-test, one-way ANOVA, Pearson correlation analysis. Smart phone addiction according to general characteristics showed the lowest in fourth grade and high in health-related majors. Smart phone usage time was the lowest in less than 3 hours due to the actual usage of smart phone. School life adaptation, self-esteem, and self-control according to general characteristics were higher in satisfaction with college life and majors. The most influential factors on the addiction of smart phone were perceived smart phone addiction, and the self-esteem and self-control were more likely to be addicted to smart phone. Therefore, it is necessary to develop education and programs to enhance self-esteem and self-control of college students and to find ways to prevent smart phone addiction.

The relative effects of individual differences in cultural orientation (individualism vs. collectivism) and locus of control (LOC: internal vs. external control beliefs) combination types on global/local processing were compared by manipulating the compound stimulus types (arrows or letters), and the stimulus-stimulus congruence. The results can be summarized as followings. First, consistent with previous research on global/local processing of the compound stimuli, reaction time (RT) for global stimuli than for local stimuli, and that in the stimulus-stimulus congruent condition than in the stimulus-stimulus incongruent condition was faster. Second, faster RT was found in the compound arrows condition than in the compound letters. Third, individual difference in LOC, rather than that in the cultural orientations, appeared to be related to global precedence effect, when the compound letters were presented. These results indicated that the individual's LOC rather than cultural orientation can increase the size of the global precedence effect, which might be involved in the stage of cognitive analysis than that of feature detection.

This study provides basic data for nursing intervention to increase self management of hemodialysis patients by identifying the relation among their illness perception, physiological indicators, and self management. The participants were 134 patients receiving hemodialysis at a general hospital in Seoul. Data were collected by using a structured questionnaire and medical records. The collected data were analyzed by using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficient and multiple regression analysis with the SPSS/WIN 23.0 program. The significant factors influencing self-management of hemodialysis patients have been identified with 8 variables. The first one is registration for kidney transplantation (β=-.20, p=.034). Among sub items of illness perception are consequence (β=-.20, p=.031), treatment control (β=.19, p=.040), and illness coherence (β=-.18, p=.049). In addition, among physiological indicators are hematocrit (β=.38, p<.001), hemoglobin (β=.29, p=.005), BUN (β=-.25, p=.010), and phosphorous (β=.22, p=.033). These variables explained 26.3% for self-management of hemodialysis patients. In order for hemodialysis patients to improve their self-management, a concrete nursing intervention improving the treatment control among illness perception as well as improving the understanding of physical indicators needs to be provided.

Previous research has demonstrated that imagined contact is useful to reducing prejudice against minorities (e.g. Turner & Crisp, 2010). In this research, we investigated whether imagined contact increases attraction to physically unattractive women, and whether this effect is moderated by perceiver's physical attractiveness and appearance orientation in romantic relationships. Single male participants (n = 98) responded to items assessing their physical attractiveness and appearance orientation, and then were randomly assigned to one of the two conditions. In the imagined contact condition, participants were told to imagine communicating with a physically unattractive woman and come up with some interesting things about her. In the control condition, participants were told to simply imagine a physically unattractive woman. Next, participants saw a picture of a physically unattractive woman and rated her likeability, perceived attractiveness, and willingness to ask her out, which were averaged to form the composite measure of attraction. We found a significant main effect of imagined contact, as expected. This main effect was moderated by appearance orientation, but not by perceivers' physical attractiveness. The effect of imagined contact was significant among those low in appearance orientation, but not among those high in appearance orientation.
