본 논문에서는 분절 특징을 모수적 궤적 모델을 이용하여 표현하고, 이 특징을 분절 HMM(segmental HMM)의 입력으로 하는 음성 신호의 모델링 방식을 제안한다. 분절 특징은 음성의 경향을 나타내는 궤적으로 표현되고, 그 궤적은 연속되는 프레임 상에서 전이 정보를 포함하도록 디자인 행렬과 다항식의 회귀 함수를 이용하여 구해진다. 이 궤적을 분절 HMM에 적용하기 위하여, 외적 분절 변이와 내적 분절 변이에 대한 확률 분포 표현을 개선하였다. 제안된 방법의 효과를 살펴보기 위하여 TIMIT 데이터 베이스를 이용하여 실험한 결과, 제안된 분절 특징은 음성 신호의 인접한 프레임간의 상관관계를 표현하는 동적 특징과 같은 효과를 보였으며, 1차 미분계수를 포함하여 분절 특징을 구한 경우에는 기존의 특징 표현보다 좋은 성능을 보였다.

본 논문은 마야(Maya) 3D 콘텐츠를 제작하는데 있어서 물, 불, 안개, 폭파 장면과 같은 특수한 효과를 표현하는 방법에 대하여 연구하였다. 마야를 이용하여 3D 콘텐츠를 제작시 특수 효과는 주로 마야의 다이나믹스를 활용한다. 본 연구에서는 마야로 구현된 객체에 에프터이펙트를 사용하여 특수효과를 표현 방법을 연구하였다. 마야 다이나믹스에 비해 에프터 이펙트는 실시간 렌더링이 가능하고, 텍스쳐 에니메이션이 마야의 다이나믹스 보다 사용하기 편리하며, 다양한 표현이 가능하다. 본 논문에서는 마야 다이나 믹스의 장단점과 에프터 이펙트의 장단점을 설명하고 각각의 효과를 적용한 결과를 제시한다.

This study examined the moderated mediation effect, consisting of the moderation effect of alexithymia and the mediation effect of hostility in the relationship between emotional labor and depression of casino dealers. A total of 160 casino dealers (56 males, 94 females) working in a foreigner exclusive casino in Seoul responded to a survey on emotional labor, alexithymia, hostility and depression. SPSS 22.0 Macro was used to verify the moderated mediation effect. First, the level of depression amplified as the emotional labor of casino dealers increased. Hostility had a significant partial-mediation effect on the relationship between emotional labor and depression. Second, the moderation effect of alexithymia was significant, indicating that the interaction effect of emotional labor and alexithymia as well as hostility and alexithymia predicted depression. Third, the moderated mediation effect of alexithymia was significant. Alexithymia moderated the influence of emotional labor on depression, which was mediated through hostility. Implications on how to assist casino dealers on emotional labor were discussed.

The purpose of this study was to examine the mediating effect of functional and dysfunctional expressions of anger on the relationship between covert narcissism and dating violence among college students. The study also investigated gender differences with regard to covert narcissism, dating violence, and functional and dysfunctional expressions of anger. To this end, 339 college students (133 males, 206 females) with heterosexual dating experiences in the Busan Metropolitan area were recruited. They responded to the Covert Narcissism Scale, the Revised Conflict Tactics Scale 2, and the Korean adaptation of the State-Trait Anger Expression Inventory. The results were as follows. First, covert narcissism, dating violence, and functional and dysfunctional expressions of anger differed significantly by gender. Second, there were statistically significant correlations between covert narcissism, dating violence, and functional and dysfunctional expressions of anger. Third, multiple regression analysis showed that dysfunctional expressions of anger for males were positively correlated with dating violence while functional expressions of anger were negatively correlated. For females, dysfunctional expressions of anger were positively correlated with dating violence while functional expressions of anger were not significantly correlated. Fourth, dysfunctional expressions of anger completely mediated the relationship between covert narcissism and dating violence for both males and females, but functional expressions of anger had no mediating effect. These results suggest that dysfunctional anger expression control program should be developed for students which may help those with covert narcissistic tendencies to functionally express their anger. Future research should analyze dating violence prevention and counseling programs.

Study on how a visual image of sex-appealing advertisement is meaningfully functioned and how customers recognize it is necessary but preceding studies about it are not sufficient. Therefore, this study analyzed effect of advertisement and its reaction according types of visual expression in sex-appealing advertisement and also, it found effective expression type of sex-appealing advertisement. As the result, according to appealing types of eroticism and pornograph, attitude on advertizement and intention of purchase showed difference and according to expressing types, there was difference in attitude on advertisement, attitude on brand, and intention of purchase. But there was not interactive effect between appealing type and expressing type. Such results implied that in using eroticism advertisement strategy, white and black color had higher expressing effect than natural color, to raise effect of brand, artistic sense and eroticism strategy were needed, and to raise intention of purchase, naked expression of pornograph was more effective.

The purpose of this study was to identify the mediating effects of positive thinking in the relationship between emotional expressivity and public speaking anxiety. Participants were recruited from one university freshmen located in Gwangju city. Data were collected from 146 university freshmen. The self-reported questionnaire was used to assess the level of positive thinking, emotional expressivity, public speaking anxiety. The SPSS WIN 23.0 version program was used with Baron and Kenny's 3-Step mediating effect and Sobel test. It was examined whether there was a mediating effect of positive thinking on emotional expression and presentation anxiety. In the second stage, emotional expressivity showed a significant effect on presentation anxiety. In stage 3, emotional expressivity was not statistically significant in presentation anxiety, and positive thinking was statistically significant in presentation anxiety. Positive thinking had a total mediating effect(z=-4.57, p<.001) in the relationship between emotional expressivity and public speaking anxiety. To reduce the public speaking anxiety among university freshmen, it is necessary to develop interventions that enhance positive thinking in addition to providing emotional expressivity.

The purpose of this study was to test the effect of socially-perfectionism on depression by mediating ambivalence over emotional expressiveness and experiential avoidance. For this purpose, 201 participants across the country conducted the survey, a measure of MPS, AEQ-K, AAQ-II, CES-D. The descriptive statistics, Pearson correlation, path coefficient were conducted using SPSS 23.0. The indirect effect was examined using bootstrap in PROCESS Macro. The results of the study are as follows. First, all the variables had meaningful positive correlations. Secondly, When socially-perfectionism affects depression, ambivalence over emotional expressiveness, and experiential avoidance were mediated. As a result, the implications and limitations of the study were discussed.

최근 컴퓨터 그래픽스에서 비사실적인 표현에 관한 연구가 되고 있다. 그 중 애니메이션 분야는 기존의 2D 애니메이션 기법을 적용하여 비사실적인 애니메이션(Non Photorealistic Animation) 을 표현할 수 있다. 여러 기법 중 기대(Anticipation) 효과를 얼굴 표정 애니메이션(Facial Animation)에 적용한다면 조금 더 역동적인 표정을 표현할 수 있게 된다. 얼굴 표정 애니메이션(Facial Animation)을 제작하기 위해서는 실제 사람의 얼굴 표정을 캡쳐하거나 애니메이터가 많은 노력과 시간을 투자하여 작업을 해야 한다. 본 논문에서는 이런 방법으로 생성된 얼굴 표정 애니메이션에 사용자가 원하는 표정에 기대 효과를 자동으로 추가하여 더 좋은 표정을 생성하는 방법을 소개한다.

Estimate of heritabilities, genotypic and phenotypic correlations and path coefficient analysis were performed for the seven characters of barley cultivars (Hordeum vulgare L.). Heritabilities of broad sense for stem length and spike length were 0.923 and 0.907. Kernels per spike, grain yield and 100 grain weight also showed high heritabilities. High genotypic and phenotypic correlations existed between stem length and 100 grain weight. Grain yield showed highly significant phenotypic correlation with spike length, 100 grain weight and kernels per spike. Genotypic correlations between those characters were moderately high. Number of stem had greatest direct effect but the number of spike had a strong negative direct effect upon grain yield. Kernels per spike via number of spike showed greatest indirect effect and the number of stem via number of spike showed strong negative indirect effect upon grain yield.
