한국영화에 대한 선호도가 이미 국내에서는 외국 영화의 선호도를 넘어선지 오래된 상황이다. 그만큼 내용적으로나 영화의 완성도를 보태주는 CG 기술 등 흥행을 뒷받침 할 수 있는 요소가 충분히 갖추어 졌다는 것이다. 그러나 여기서 주목하지 않을 수 없는 것은 바로 출연 배우들의 연기력이 아닐 수 없다. 이 같은 관점에서 본 논문에서는 우선적으로 우리나라 남자 주연배우들의 인터뷰 속 목소리의 공통점은 무엇이고 이것이 의미하는 바가 무엇인 지에 대해 음성 분석 기술을 통해 이를 정량적, 시각적으로 추출, 분석해 내는 방법을 제시하고자 한다.

일반적으로 실제 유역에서의 계절 유출예측을 위해서는 계절 기상예측에 기반한 장기유출모델링을 수행하고 있다. 그러나, 대부분의 하천에는 하천유량의 자연적인 흐름체계에 인위적인 영향을 야기하는 댐이 건설되어 운영되고 있는 실정이다. 즉, 자연상태의 유역이 아닌 댐이 위치하고 있는 복잡한 유역에서는 반드시 저수지 운영이 고려된 유출모델링이 수행되어야 한다. 따라서, 본 연구에서는 장기유출모형의 대표적인 모형 중 하나인 SWAT의 저수지 운영모듈의 성능을 평가하고자 하였다. 한강에 위치한 다목적댐인 소양강, 충주댐을 대상으로 SWAT에 탑재되어 있는 저수지 운영모듈의 적용시 한계점을 검토하고, 이를 극복하기 위한 모듈개선을 시도하였다. 또한, 각 댐의 방류량, 저수지 수위를 중심으로 모듈개선 전후의 모의능력을 검증하였다. 저수지 운영과 관련된 모의성능은 인위적인 저류시설물이 위치하는 복잡한 유역의 유출분석시 반드시 검토되어야 하는 사항이며, 모델링을 통한 저수지 운영의 평가와 가뭄대응을 위한 비구조적 대책 수립시 매우 중요한 기능 요소이다.

This study examined how practical reasoning processes were reflected in the revised consumer education of technology & home economics textbooks in secondary schools. Twenty-four textbooks from secondary schools for 7th to 10th grades were analyzed. Areas of textbooks analyzed were introduction, body content, learning activity, and evaluation. Analysis criteria were extracted from the previous literature regarding contents and questions dealing with practical reasoning processes and revised by a researcher of this paper. The results and conclusions of this study are as follows. The results of the analysis of the practical reasoning processes showed that, across all grades, "contexts" was the most common element, and "alternatives and means" was the second most common elements. The elements of "consequences", "action and reflection" were less represented in the textbooks, with the exception of the learning activity part. The types of practical reasoning process reflected were classified either as the entire process of reasoning being reflected or some of the process being reflected, or included in the body content. Most of these were some of the process being reflected. Since there were a lot of concept-oriented statements rather than questions, more practical reasoning questions should be developed to increase the reasoning process. In addition, a need exists to develop a variety of ways to utilize the entire practical reasoning processes in the textbooks to help teachers apply the practical reasoning processes to their lessons.

According to the demand for services. a single point contract between a user and provider spreads over the industry, and the relationship between them is a main issue. The user wants to make a deal with the contributor which can provide the effective services to the user. This study is to estimate the efficiency of global logistics industry with Data Envelopment Analysis, by nations from 2001 to 2005. Furthermore, it tries to estimate the inefficiency affected by macro factors, and proves the association between them using Tobit model. Global logistics industry has made growth both externally and internally more than doubled for the last 5years. Technical inefficiency of global logistics industry is more influenced by pure technical inefficiency than inefficiency of scale. Therefore technical efficiency can be increased by decreasing pure technical inefficiency. Through this study, it found that the logistics industry got influenced to its efficiency by high price of oil, and courier and transportation service market is formed stably. Furthermore, it advocates policy planners to consider effectiveness and clearness of policy which influence to inefficiency of logistics industry. Also, it found that labor and financial support can give critical effect.

Superhero films have formed a new genre convention encompassing all the generations. Figures derived from image contents are solid figures produced by means of professional figuration skills. Possession of figures has a symbolic meaning as a medium connecting the imaginary world and real one. From this perspective, figures hold an important position as a character product derived due to market expansion of the content industry. In this context, the study, which analyzed how appraisal of outward visual elements in superhero action figures might affect consumer's purchase intention, aimed to identify their purchase patterns. For this, the study established colors, types of physical body, facial figures and motions as independent variables for appraisal of outward visual elements, and purchase intention as a dependent variable and then conducted a multiple regression analysis. As a result of the analysis, the study found that colors, types of physical body and facial figures had a positive influence on purchase intention, while motions had no significant influence.

To date, the literature has focused on formal R&D activities, such as internal, joint or external R&D, but informal R&D activities, such as job training or design, can also have a positive impact on technological innovation. To address this research gap, this paper examined 1) the influence of informal R&D activities on innovation adoption, and 2) the differences between formal R&D-oriented and informal R&D-oriented firms in process and product innovation. For this, statistical analysis was conducted using the data set from 2012 Korea Innovation Survey. The results suggest that 1) informal R&D activities can influence process innovation, and 2) firms engaging in both informal and formal R&D actively adopt product innovation. Findings suggest that 1) firms should recognize the importance of informal R&D and 2) national R&D policy should reflect the positive role of informal R&D in technological innovation.

The main purpose of this study was to empirically investigate the effects of participation behavior and performance improvement on motivation factors of Korean university students which participated in LINC by utilizing Vroom's Expectancy Theory. Three motivation factors of valence, instrumentality, and expectancy were examined in this study. In addition, two different models (valence and force model) analyzed the causal relationships regarding participation behavior and performance improvement. 236 data were collected and findings of this study were as follows: First, comparative analysis between demographic characteristics including university, major, and residence had no significant differences in mean value. However, females had higher levels of recognition related to valence (attractiveness) relative to males. Second, valence and the force model were significant predictors of LINC participation behavior and performance improvement. Furthermore, the coefficient of determination and beta coefficient of the force model were higher compared with the valence model. Third, the level of mediation effects including direct, indirect, and total effect of the force model was higher than the valence model. LINC participation behavior had a partial mediating effect between the three motivation factors and performance improvement variable.
