In the paper, this study will be explored in the migration of the mask dance Eunyeul Talchum from North Korea to South Korea after the national division took place. During and after the Korean War, refugees from the Hwanghae province settled in the Republic of Korea who were performers of the three Korean mask dances: Bongsan Talchum, Kangryeong Talchum and Eunyeul Talchum. All of these mask dances are denoted as South Korea's National Intangible Properties under the Cultural Property Protection Law (1962.) However, Eunyeul Talchum is the only asset among these three that settled in Incheon, instead of the capital, Seoul. The purpose of this research is to examine the process of restoring and the idea of transmitting Eunyeul Talchum in Incheon after the division of Korea. As opposed to Bongsan Talchum and Gangryeong Talchum, which are recognized as major socio-ethnic groups, Eunyeul Talchum belongs to a minority. Because not only Eunyeul Talchum is the last Mask Dance which has been nominated as an Intangible asset among the other Hwanghae Talchum but also, most people in the preservation association are comprised of the second-generation refugees from Hwanghae province. During three months of research, the researcher observed the performances and the educational communicating Eunyeul Talchum's cultural legacy. This study included several research methods: open interview, examination of relevant documents, and live performances. Particularly, the researcher conducted interviews with the Human Cultural Property and musicians (including professional/scholarly to lay/untrained) in the Preservation Association. In conclusion, Eunyeul Talchum preservation association is not as preeminent as other Korean mask dances, it has been transmitted by performers from Hwanghae province with its unique masks and instrumental accompaniment. These performers and educators dedication to maintaining Eunyeul Talchum's attributes contribute largely to the Preservation Association's successful settlement in Incheon. Thus, the researcher examines which idea formed to subsist the Eunyeul Talchum preservation association.

The purpose of this paper is to introduce the concept of negative DEA, which aims at identifying worst performers by placing them on the efficient frontier, This paper also proposes to use a layering technique instead of the traditional cut-off point approach, since this enables incorporation of risk attitudes and risk-based pricing. The results of the empirical application on credit risk evaluation validate the method which is proposed in this paper.

Small Group Collaborative Instruction in school settings has been endorsed by many educational experts over the years. Some studies found that learners greatly benefit from one another through communication and interaction with their peers. These studies previously indicated improvement of a learner‘s academic ability as well as the application of the affective domain when using this type of instruction. Lower-level students with limited mathematical abilities improved their problem-solving and conceptual thinking skills when tasked to work with other learners. On the other hand, the effectiveness of this process was questioned to be less evident with higher-level performers. Therefore, this study was designed to observe the efficacy of Small Group Collaborative Instruction on higher-level students and to explore their learning process as they interact with and teach lower-level students. This study observed that higher-level students use high-level mathematical thinking skills when helping lower-level students, and they improved problem-solving ability as well as communication skills.

Performance costumes are an important element in the stages which set the tones and embody characters in the performances. This study focuses on Gisaeng's costumes in folk dance performances when Korea experienced modernization from Joseon Dynasty, and aims to examine the features of the costumes as well as how the costumes both influenced, and got influenced by, the rapidly changing society. Gisaeng had been legal entertainment performers of the government in the Joseon Dynasty and, despite careful training and talents, had inferior social status in Joseon's social hierarchy system. In the modern society, a new system of Gisaeng emerged and the first public theater opened. The advent of theaters changed performance stages and the ways performances are conducted. This study investigated Gisaeng's performance costumes by the type of folk dances, such as monk dance, palace dance, Salfuri dance, Jangu dance, and Ip dance. The study brings light to three conclusions. First, as folk dances which had been performed by civil dancers were spread to Gisaeng, Gisaeng's costumes absorbed the costumes of civil dancers. Also, royal costumes appeared in folk dance performances. This can be viewed as mixture of royal and folk dance costumes, resulted from interactions between Gisaeng and civil art performers associated with the modernizing society and the weakening of the old hierarchical class system. Second, as performing arts on stages were modernizing, performance costumes changed accordingly. Thirdly, Giseang's costumes in folk dances also adapted the introduction of the western culture, which largely influenced the fashion trends of people in the early modern society in Korea.

This study proposed the design development of performance uniform for Korean classical music. To do this, we considered the state of the performance uniform of the Korean Classical Music Band through photographic data. The research targeted the performers in Korean Classical Music Band, and conducted a survey for the preference of type, pattern, decoration, color and fabric materials. Based on the results, we extracted the design of performance uniform, which is suitable for the environment of Korean classical music performance and meets the substantial requirements of performers. The performance uniform that the current national or public Korean classical music bands are using, has two types: Western clothing and Hanbok. The attire is influenced by the genre of the music that they are playing because one of its main functions is to deliver the music to audience effectively. In addition, there are some differences in the uniform based on the gender, but no division in the design of clothing according to music instruments. However, the result of the survey show that there was no difference in preference by gender, but there was some difference according to the division of music instruments. On this study, we reflected this result in the design, and proposed the design of an convenient outer garment for everyone to wear in the music performance band.

R&D is inherently an uncertain endeavor, yet now more than ever those performing R&D with public funding are called upon to clarify the utility of their research. Calls for public accountability are mounting with the increase in constraints on government budgets due to the recent worldwide economic recession, in response to which both policymakers and researchers pay much more attention to rigorously assessing publicly funded R&D. A key issue complicating R&D evaluation in these circumstances is how to adequately account for the nature and degree of risk involved in a given R&D program or project. This study deliberates on certain issues involving the measurement of ex-ante risk in public R&D evaluation: (i) information asymmetry between R&D sponsors and performers, (ii) ambiguity in the measurement of returns in both prospective and retrospective evaluation, and (iii) the dilemma between measurement error and omitted variable bias for empirical estimation of R&D performance. The study then presents an analysis of hypothetical evaluation results that apply risk-relevant weights to the annual evaluation outcomes of South Korea's national R&D programs funded during 2006~2012. In this counterfactual re-evaluation of public R&D program performance, high-risk R&D programs turn out to receive higher evaluation than non-high-risk programs. The current study suggests that R&D evaluation ignoring ex-ante risk is not only conceptually invalid since R&D activities are intrinsically uncertain endeavors, but unfair as R&D performers are asked to be accountable for the results that were in fact out of their reach.

The purpose of this study is to introduce the effect of attentional focus on performance of task. Previous studies has shown that motor learning can be enhanced by directing performers's attention to the effects of their movements(external focus), rather than to the body movement producing the effects(internal focus). Wulf and colleagues have invoked the 'constrained action hypothesis' to explain the comparative benefits of adopting an external rather than an internal focus of attention. This hypothesis proposed that when performers utilize an internal focus of attention, they may actually constrain or interfere with automatic control processes that would normally regulate the movement, whereas an external focus of attention allows the motor system to more naturally self-organize. Electromyography(EMG) was used to determine neuromuscular correlates of external versus internal focus differences. EMG activity was lower with an external relative to an internal focus. This suggest that an external focus of attention enhances movement economy, and presumably reduces 'noise' in the motor system that hampers fine movement control. Focusing on a more remote effect seems to facilitate the discriminability of the effect from the body movements that produced it and to be more beneficial than focusing on a very close effects. There might be an optimal distance of the effect, at which ti wis easily distinguishable from the body movement but at which it is also still possible for the performer to relate this effect to the movement techniques. Future Studies of motor learning of patient need to accommodate these new finding and account for the role of the learner's attentional focus and its influencing on learning.

This study analysed motion graphic formative image composition of TV LED backdrop to be used as background display for performers such as singers appeared on TV music show. Motion graphic LED images are comprised of various plane figures, and backdrop's design function as background screen has a goal to convey synesthesia and sensibility of visual elements. And this analyse classified sensibility concept about color, motion direction and speed to be elements of transmitting sensibility. As the analyse of graphic form among transmitting sensibility elements, this classified form type into its' applied elements, and studied how these elements' motion pattern and arrangement could be placed and replaced at song's four step composition, intro, verse, bridge, chorus part, and also characterized differences of backdrop design for male and female performers. As a case study, it included terrestial broadcasting TV song ranking shows targeted at teenagers. Because they carried out various motion design utilizations. Finally, this reasoned out mainly designing form type, its' applied elements, motion pattern and its' arrangements type division according to the song developing four steps.

A stochastic modeling approach as a mathematical method for workflow intelligence is widely used for analyzing and simulating workflow models in the literature. In particular, as a resource-centric modeling approach, this paper proposes a stochastic model to represent work-handover relationships between performers in a workflow-supported social network. Calculating probabilities for the work-handover relationships are determined by two types of probabilities. One is the work-transition probability between activities, and the other is the task assignment probability between activities and performers. In this paper, we describe formal definitions of stochastic workflow models and stochastic work-handover relationship models, as well. Then, we propose an algorithm for extracting a stochastic work-handover relationship model from a stochastic workflow model. As a consequence, the proposed model ought to be useful in performing resource-centric workflow simulations and model-log comparison analyses.

In this paper, we propose an activity-performer bipartite matrix generation algorithm for analyzing workflow-supported human-resource affiliations in a workflow model. The workflow-supported human-resource means that all performers of the organization managed by a workflow management system have to be affiliated with a certain set of activities in enacting the corresponding workflow model. We define an activity-performer affiliation network model that is a special type of social networks representing affiliation relationships between a group of performers and a group of activities in workflow models. The algorithm proposed in this paper generates a bipartite matrix from the activity-performer affiliation network model(APANM). Eventually, the generated activity-performer bipartite matrix can be used to analyze social network properties such as, centrality, density, and correlation, and to enable the organization to obtain the workflow-supported human-resource affiliations knowledge.
