The meaning of things appeared in the frame vary according to how they look in a shot. Especially, position of frame shows how a form becomes a content in quality. This has a large impact on communication with audiences, reminds them a special feeling or atmosphere toward an object and plays a suggestive role for things that shows up. Thus, this study aimed to investigate how symbolisms appeared in the frame position are shown in the relation among characters' narrative, personality and conflict and understand correlation between frame position and characters accordingly. As an object to be analyzed, this study selected which was played with narratives of couples with different personalities. The results of analysis shows that it is deeply associated with couples' narrative, which means that trauma or the severance of relations between a couple is shown on left side, whereas a positive and future-oriented couple was mainly shown on right side and the rate of being situated in the center turned out to be high according to the power relations of love. Based on the comparison between symbolism appeared according to the frame position and narratives and traumas that various characters have, this study found that frame position is playing an important role in composing characters' personality.

We proposed the blocking channel to reduce the performance decrease using the low correlation with cyclic delay scheme in LED-ID system. LED-ID is based on the visible light to transmit the data. However, It is occurred the block channel by structure or environment of indoor for light of straightness. LED-ID system is degraded the performance by the block channel as loss of data, and burst error. To solve the block channel, the proposed system is overcome the burst error by low correlation among data, which is able to obtain the maximize time diversity gain to improve the performance of BER by cyclic delay scheme. The BER performance is evaluated by computer simulation according to channel parameter. The simulation results shows that proposed system gives much better performance than conventional system and constant cyclic delay scheme system.

Despite the increasing importance that companies currently place on employee wellness, few studies have explored the impact of wellness on individual and team performance in the workplace. Drawing on the broaden-and-build theory, we hypothesize that wellness intention, wellness leadership, and wellness climate influence the performance of both individuals and teams. We tested our hypotheses using data collected from 495 employees of 81 teams in 11 Korean companies. Our analysis indicates that wellness leadership and wellness climate are meaningful interventions between perceived wellness and performance. Wellness intention did not impact perceived wellness. However, the interaction between wellness intention and wellness leadership impacted perceived wellness. Wellness climate negatively moderated the relationship between perceived wellness and performance.

This The purpose of this study is to find policy implications through the analysis of the operational cases and establishment performance of the Leading University for startups. The method of the study was statistical analysis using the data generated during the operation of the Leading University for startups. The results of the study show that there is a difference between short-term performance by gender and age. Second, there was no correlation of the short-term performance with the evaluation, but a negative correlation was observed with the detailed document evaluation part. Third, there is no difference in short-term performance depending on the mentor. Strategic utilization is to reduce the reflection of the founder's short-term performance in the appraisal of the Leading Universities. And there is a need to improve the evaluation method for the applicant. The limitations of this study are that it is inadequate to be an empirical study through statistical analysis. And statistical analysis shows that there are not enough cases. Therefore, I will make an empirical study which will expand the number of cases by including cases of several universities in the future.

The purpose of this paper is to examine how technological innovation and increasing competition affect the relationship among market players and what policy issues are emerging through the case of UHDTV. There emerges sharp conflicts among consumer-electronics companies, telcos, terrestrial broadcasting companies and pay-TV companies since they all have different perspectives and interests regarding the way UHDTV services are introduced in the competitive broadcasting market. Dualized governance structure leads to aggravating conflicts. While the case of UHDTV demonstrates clearly that technological innovation and more competition into the market create conflicts among these market players, it is well expected that we will see very often similar conflicts and policy chaos in this innovative and competitive broadcasting industry.

Background: Viral infection outbreaks are emerging public health concerns. They often exhibit seasonal patterns that could be predicted by the application of big data and bioinformatic analyses. Purpose: The purpose of this study was to identify trends in diarrhea-causing viruses such as rotavirus (Gr.A), norovirus G-I, and norovirus G-II in Cheonan, Korea. The identified related factors of diarrhea-causing viruses may be used to predict their trend and prevent their infections. Method: A retrospective analysis of 4,009 fecal samples from June 2010 to December 2019 was carried out at Dankook University Hospital in Cheonan. Reverse transcription-PCR (RT-PCR) was employed to identify virus strains. Information about seasonal patterns of infection was extracted and compared with local weather data. Results: Out of the 4,009 fecal samples tested using multiplex RT-PCR (mRT-PCR), 985 were positive for infection with Gr.A, G-I, and G-II. Out of these 985 cases, 95.3% (n = 939) were under 10 years of age. Gr.A, G-I, and G-II showed high infection rates in patients under 10 years of age. Student's t-test showed a significant correlation between the detection rate of Gr.A and the relative humidity. The detection rate of G-II significantly correlated with wind-chill temperature. Conclusion: Climate factors differentially modulate rotavirus and norovirus infection patterns. These observations provide novel insights into the seasonal impact on the pathogenesis of Gr.A, G-I, and G-II.

Supply chain in service sector has been established on the premise that firms need to manage their process uncertainties to satisfy customers in an efficient manner. Information sharing and synchronization play key roles in minimize uncertainties from their involved supply chain. The duality of customers being inputs providers as well as consumers, differentiates service supply chains from manufacturing and is a challenging issue to traditional supply chain management. The service supply chain is a structured network which should be managed with supply chain theory and principles. Various key operations need to be carried out through a highly integrated and collaborated service supply chain and supporting information hub. The purpose of this paper is to present the issues and key components in the service supply chain, where the repetitive service is provided along the value chain, such as tourism, restaurant, mega-sized hospital supply chain.
