We identified a competition network which has never been studied before and investigated the relationship between centrality of participants in singing competition and their winning percentage within the competition network. We collected competition data from 'Immortal Songs: Singing the Legend', which is a Korean television music competition program, and constructed a competition network. We calculated centrality and winning percentage and analyzed their relationship using correlation analysis, regression analysis, and visualization. There are four main findings in this research. First, a competition network is a scale-free network whose degree distribution follows a power law. Second, there is a logarithmic relationship between the count of competition and closeness. Third, winning percentage converges to approximately 60% for players who have participated in more than 20 competitions. Lastly, a strength of opponents affects approximately 23% of winning percentage for players with less than 20 competitions. The academic significance of this study is that we pioneered the definition of the competition network and applied social network analysis method. Another significant contribution of this paper is that we found explicit patterns between the centrality and winning percentage, suggesting ways to improve social relationship in competition network and to increase winning percentage.

High speed cutting processes of rigid flexible printed circuit board by making use of high power UV laser with nano-second pulse width have been proposed and investigated experimentally. Also robust laser cutting system has been designed and developed in order to obtain a good cutting quality of rigid and flexible PCB with multi-layers (2-6 layers). Power controller module developed for ourselves is adapted to control the laser output power in the range less than 1%. The systems show the good performance of cutting speed, cutting width and cutting accuracy, respectively. Especially we have confirmed that the short circuit problem due to the carbonized contamination occurred in cross section of multi-layers by thermal effect of high power laser has been improved largely by using multi-pass cutting process with low power and high speed.

This article discussed the components of traditional art competitions held from 1930 to 1941. Of their various components, observations were made of hosts and sponsors, participants, and evaluations with a focus on the backgrounds and objectives of hosts and sponsors, participant aspects, and evaluation forms. Hosts and sponsors included newspaper companies, social organizations, music companies, stores, individuals, and eups. They hosted and sponsored traditional art competitions with their own respective reasons and justifications and there were multiple commercial and promotional objectives at the base. Participant aspects can be divided into gisaengs and male artists. While the participation of gisaengs was a natural phenomenon, aspects of the traditional art performance world of the 1930s and the quantitative increase of gisaengs had great effects and male artists participated because of the hidden purpose of the competitions, which was the discovery of traditional artists. Evaluation forms were divided into audience evaluations and expert evaluations. Audience evaluations began from 'pan' culture of the past and audience members involved themselves by casting votes and expert evaluations, in which master singers, master dancers, instrumentalists, and lyricists participated, came to the fore through expert courses of traditional art competitions.

The purpose of this study is to recognize the differences of visual evaluation by variations in silhouette of the wide pants. The stimuli are 9 samples: One control group, 3 variations of the width of hem line and 3 variations of the silhouette. The data has been obtained from 57 fashion college students. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test. The results of the study are as follows: The visual evaluation by silhouette of wide pants are composed of 5 factors(i.e., physical characteristics, complexity, attractiveness, originality, and stiffness and softness). Among these factors, the physical characteristic is evaluated to be the most important factor. The straight pants were the most attractive and modern when the width of the hem line was 66cm (1st stage), while the pants were uncomfortable and unwearable when the width of the hem line was 98cm (3rd stage). The bell-bottom pants were evaluated to be the most attractive with the average width of the hem line. When the width of the hem line of the flare pants were too wide, it was uncomfortable and unwearable but had its unique originality. When the width of the hem line was narrow, the visual image changed as the pants' silhouette varied. However, when the width of the hem line was wide, the visual image did not change by silhouette.

To investigate the incidence status of lily viruses on Jeju island, lily samples were collected from 2015 to 2018 and examined for virus infection using RT-PCR. Of the viral infections, mixed and single infections were 70.0% and 17.9%, respectively. The incidence of mixed infections was highest for PlAMV and LSV as 43.4% in 2015; PlAMV, LSV 33.1% in 2016; LSV, LMoV 10.2% in 2017; and PlAMV, LSV, LMoV and CMV 15.8% in 2018. The incidence of PlAMV was observed to be 82.0% in 2015, 49.4% in 2016, 13.6% in 2017, and 39.5% in 2018 after the first occurrence of PlAMV in 2013. No symptoms were observed for single infection with LSV. However, in the case of mixed infection with LSV and LMoV, mosaic and leaf malformation symptoms appeared. With mixed infection with LSV and CMV, pale brown necrotic spots appeared, and mosaic and leaf curling were induced. PlAMV was more common in mixed infection than in single infection, and caused necrosis following the development of reddish-brown spots. PlAMV significantly decreased the marketability of lilies owing to the generation of leaf anomalies and curls, and its symptoms were more severe in mixed infections.
