영상실감증대를 위한 시각, 청각정보의 제시방식에 대해서는 많은 진보가 이루어 졌다. 반면 후각은 정의하기 어렵고 다루기 까다롭기 때문에 관련연구를 찾아보기 어렵다. 본 연구에서는 후각정보를 통한 영상실감증대 연구의 첫걸음으로 후각정보에 대한 사용자 수용도를 조사한 후 이에 근거하여 다양한 영상을 분류하였다. 이를 위해 먼저 영상에 냄새가 존재하는지 (냄새존재여부), 영상과 함께 해당 냄새를 경험하고 싶은지 (냄새제시선호), 영상에 어울리는 냄새가 내가 좋아하는 냄새인지 (냄새자체선호), 그리고 영상에 어울리는 냄새가 얼마나 구체적인지 (냄새의 구체성)라는 네 가지 질문을 선정하였다. 각 질문들에 높은 혹은 낮은 점수를 받을 만한 다양한 장르의 영상 (51)개를 수집한 후, 참가자들에게 하나씩 영상을 시청하게 한 후 위의 네 가지 질문에 대해 7점 척도로 평정하게 하였다. 영상분류를 위해 두 질문씩 쌍으로 묶어 각 질문의 척도를 2차원 평면의 X, Y축으로 설정한 후 평정값을 이용하여 영상분류를 위한 산포도를 구성하였다. 2차원 평면의 서로 다른 사분면에 위치한 영상군집들은 영상실감증대를 위한 후각정보 제시에 중요한 시사점을 줄 것으로 기대한다.

The suspense will be realized as various techniques influenced the perception of audience organically each other. These varied techniques induce isolation as well as a restricted space as formal system. Moreover, it could intensify emotional experience of audience that they will not escape in addition to the depth.. This study chose a movie (2010) and <127 hours> (2010) which used the limited space as the material as the analysis target to examine. It is the goal of this study to analyze the conversion of careful viewpoint and the flashback, and to raise the meaning of the suspense expression through this. The researcher would consider how the suspense is expressed based on the conversion of viewpoint and how the flashback delivers the psychology and emotion.

최근에는 정보 가전의 사용이 크게 증가하였고, 다양한 제품 출시와 기술의 발전에 힘입어 제품에 따른 사용성에 있어 큰 차이가 없게 됨에 따라 사용성(usability)의 개념(Gould and Leuis, 1985; Benner, 1984)이 단순한 편리성과 기능성에서 사용자의 경험을 중시하는 방향으로 확장되었다(Carroll, J.M., 2004). 이러한 측면에서 유희적인 측면은 점점 강조되고 있는 실정이다. 아이콘은 GUI 환경에서 사용자가 이루고자 하는 바를 실제 공간에서 대상을 직접 조작하는 방식과 비슷하게 조작할 수 있도록 해줌으로써 중요한 구성요소로 인식되고 있다. 하지만 지금까지 아이콘과 관련된 대부분의 연구들은 아이콘의 기능적인 측면만을 다루어 왔으며, 아이콘이 가질 수 있는 재미나 즐거움과 같은 유희적인 측면에 대한 연구는 거의 이루어지지 않았다. 본 연구에서는 재미와 즐거움을 유희적인 요소로 규정하고 아이콘의 사용성과 주관적인 평정에 있어 재미가 어떠한 영향을 주는지 알아보았다. 그 결과 전형적인 인터페이스와 재미있는 인터페이스는 객관적인 사용성(Ergonomics quality)에 있어서 차이가 나지 않았음에도 불구하고, 사용자들은 재미있는 인터페이스에 대해 더 호감이 가고 매력적이고, 좋다고 평가하였다. 본 연구는 아이콘 디자인에 있어 기본적인 기능을 유지하면서도 참신성을 기준으로 재미요소를 추가하였을 때에 본래의 아이콘이 가지는 장점을 살리면서도 사용자의 경험을 풍부하게 해줄 수 있다는 것을 발견했다는 점에서 의의가 있다.

Purpose: This study aims to investigate major traumatic events experienced by nurses in regional trauma centers and explore the relationship among their traumatic events experience, perceived stress, and stress coping. Methods: Data were collected from 208 nurses in the trauma emergency room (trauma-bay) and trauma intensive care unit at four regional trauma centers. Results: The mean score of the traumatic events experience was 44.3 out of 76 points. The scores for physical injuries caused by traffic accidents or falls as well as patient care with abnormal behaviors were high. Significantly positive correlations among traumatic events experience, perceived stress, and stress coping were identified. Conclusion: Nurses working in the regional trauma centers experienced many various traumatic events, leading to high levels of stress. This study suggests that it is necessary to establish a regular surveillance system for nurses' traumatic events experience and perceived stress.

With rapid growth and competition of electronic commerce through internet, various buying types and business models are being appeared In this paper, we studied group buying which is new business model to consumer and factors affecting on trust and participation of group buying. The following are the regression result of this study. First, factors affecting on trust of group buying were different from factors affecting on participation of group buying. Second, perceived reputation factor, familiarity factor and product value factor made a significant effect on participation of group buying. Third customer service factor didn't make a significant effect on both participation and trust of group buying. Fourth, product value factor made a significant effect on both participation and trust of group buying. Fifth trust of group buying made a significant effect on participation of group buying

Purpose: Purpose of this study was to examine the effects of the Mindfulness Meditation program on perceived stress, ways of coping, salivary cortisol level, and psychological stress response in patients with breast cancer. Methods: This was a quasiexperimental study with a non-equivalent control group pre-post test design. Participants in this study were 50 patients who had completed breast cancer treatment (experimental group, 25, control group, 25). The experimental group received the Mindfulness Meditation program for 3 hours/session/ week for 8 weeks. Data were analyzed using $X^2$-test and t-test for subject homogeneity verification, and ANCOVA to examine the hypotheses. Results: The experimental group had significantly lower scores for perceived stress, emotional focused coping, salivary cortisol level, and psychological stress response compared to the control group. However, no significant differences were found between two groups for the scores on problem focused stress coping. Conclusion: According to the results, the Mindfulness Meditation program was useful for decreasing perceived stress, emotional focused coping, salivary cortisol level, and psychological stress response. Therefore, this program is an effective nursing intervention to decrease stress in patients with breast cancer.

In this paper, we discuss the scale of subjective speech quality measurement over VoIP(Voice over IP) network which is a component of broadband networks. Objective parameters of multimedia services like PSNR or jitter can easily measured and defined, but these factors are not easily meet the user's perceptual recognition. We suggest the speech quality measurement scale through the subjective measurement for end-to-end speech quality composed of sender-side quality, transmission quality, receiver-side quality, which provide the degree of correctness of representation of speaker, the degree of impairment caused by various factors, the degree of recognition of processed speech, respectively. Also, we examined the proposed method and verify it's availability.

This study investigated the influence of perceived parenting style on the sense of community of middle-class adolescents and if adolescent' life satisfaction has a mediating effect on the relationship between perceived parenting style and sense of community. The study population consisted of a nationally representative sample of elementary and middle school students who completed the Korean Children and Youth Panel Survey of the National Youth Policy Institute in 2010. Among the 4,729 participants of the data, 2,876 were eligible for research focused on the middle class. Descriptive statistics included frequency, average, and standard deviation; in addition, reliability and stepwise regression results were reported using SPSS statistics. The results were as follows. First, the sense of community was 2.86 out of 4-point Likert scale. Monitoring (3.28) was the highest among the perceived parenting styles followed by affection (3.17), reasoning (3.01), over-expectation (2.57), over-interference, and inconsistency (2.40). Second, among subcategories of perceived parenting style, affection, reasoning, monitoring, and over-expectation had a statistically significant influence on sense of community. A higher perceived parenting style had a higher sense of community of middle-class children. Third, the life satisfaction of children had a statistically significant moderating effect on relationship between perceived parenting style and sense of community; therefore, the influence of perceived parenting style on sense of community could change according to life satisfaction.

This study investigated the effect on reducing the pressure rise rate(PRR) in HCCI Engine by the variation of mixing ratio in the pre-mixture of DME and n-Butane that has different auto-ignition characteristics. In addition to measure of gas pressure in the engine cylinder, chemiluminescence image using the optical accessible engine and numerical analysis with multi-zones model were used to assess the combustion at each local area in the combustion chamber. The maximum PRR changes depending on mixing condition of DME and n-Butane. When DME is stratified and n-Butane is distributed uniformly, maximum PRR becomes lowest which is about 0.25MPa/ms and it corresponds to 5deg. retarding of CA50.
