Not many years ago, people found the contemporary technology expensive and difficult to use in collaborative type of meetings. Today, with the technology advanced to high standards and accessible at cheaper price, its adaption is becoming more and more ubiquitous with wide range of applications. Today's meeting rooms are not just plain old telephone systems with microphones and speakers. Today's meeting rooms are smart and intelligent. They can identify the participants; they can provide natural view of remote participants; they can proactively manage resources for collaboration and so on. More effective collaboration is possible with deployment of devices like high-definition cameras, advanced displays, sensors, gigabit networks, trackers, pointers, and high-end audio devices. Devices alone are not enough in the meeting rooms. We need software infrastructure to manage the devices and meeting contexts. One such software infrastructure is SMeet, a Smart Meeting space, which we have developed to provide an effective multi-party remote collaboration environment. Networked display systems are used in such advanced collaboration environment for better visualization. In this paper we discuss a novel approach to control and manage networked display systems in SMeet environment.

As global competition of enterprises heats up recently, there is a growing the need to introduce business knowledge platform. Many enterprises work with other partners in a variety of situations and collaboration has emerged as new competitiveness of them. Collaboration improves the performance of members, and besides it has an important bearing on innovation, result, and increased productivity of enterprise. Lots of businesses, locally and abroad, extend the environment of collaboration and try to share business contents efficiently. In addition, they look into ways of invigorating collaboration by providing community tools. Corporations and Governments around the world are pushing smart work to respond effectively to this paradigm change. Smart work provides many types of collaboration and raises the productivity. Various infrastructures should be constructed for activating smart work. Most of all, core technology is to be developed. Virtual Cluster is the space of collaboration corresponding to change in business paradigm. In overseas policy of Virtual Cluster has been already enforced as an alternative to geographical cluster. The establishment and development of collaboration platform through Virtual Cluster can contribute to business competitiveness by smart work.

Productivity improvement is one of the important goals which firms' technology developments aim at. Firms' improved productivity from technology development means that their inputs can produce more outputs through technology development, which makes firms' productivity improvement from technology development more and more important in the age of technology advance and convergence like today. This research empirically analyzes the influence of the external technology collaboration network diversity on the productivity improvement of the small and medium-sized enterprises (SMEs) from technology development and the moderating effect of the chief technology officer (CTO)-driven technology development on this influence. This study constructs the research model reflecting the moderating impact of the CTO-driven technology development and tests it with the ordinary least squares regression through the IBM SPSS version 23 by using the 2,000 data about South Korean SMEs. This research empirically reveals two points. One is that SMEs' external technology collaboration network diversity has a positive influence on their productivity improvement from technology development. The other is that the positive effect of SMEs' external technology collaboration network diversity on their productivity improvement from technology development is moderated by the CTO-driven technology development. The two points revealed in this study present two meaningful implications in not only the practical but also academic point of view. The practical implication is that it is effective for SMEs to use CTOs in increasing their productivity improvement from technology development. The academic implication is that making technology collaboration with more diverse external partners can increase SMEs' productivity improvement from technology development.

In this study, we investigated the total phenolic and flavonoid contents, component analysis, antioxidative activity and cellular protective effects against oxidative stress on human skin cells in 50% ethanol extract, ethyl acetate fraction and aglycone fraction obtained from Gynostemma pentaphyllum (G. pentaphyllum) Makino. The DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activites ($FSC_{50}$) of the 50% ethanol extracts, ethyl acetate fraction and aglycone fraction were 246.8, 147.2, $128.9{\mu}g/mL$, respectively. Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of the 50% ethanol extract, ethyl acetate fraction and aglycone fraction on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system using the luminol-dependent chemiluminescence assay were 37.15, 10.74, $7.19{\mu}g/mL$, respectively. We investigated the cellular protective activity and the results showed that treatment of aglycone fraction ($0.05-0.39{\mu}g/mL$) protect human skin cells in a concentration-dependent manner when the skin cell damages were induced by treating them with $H_2O_2$. These results suggest that extract/fractions of G. pentaphyllum Makino may be applicable as natural antioxidants in cosmetics.

The fourth Industrial Revolution, known as digital transformation, has made MZ generation to be the focus of the new consumer market, brought about the use of technological platforms a new consumption method. Currently, as various types of content collaboration are emerging that specifically targeting at the MZ generation. Content collaboration are considered an integration of content to create new values through co-existence and co-prosperity. This study identified the characteristics of collaboration of fashion brands from 2018 using literature and online news articles, and identified and classified through case studies of it determined movie content, game and virtual characters. By this research, it shown that collaboration with movie contents have increased the collaborative synergy by using the story in global media content. Collaboration with mobile games was generally used by young casual and sportswear brands. These brands which utilized characters from mobile games popular with to attract more teen consumers and strengthen brand awareness by adding values of high-technology and scarcity to the familiar images. In addition, collaboration with virtual characters has expanded value of the collaborative approach on expanding the range of advanced digital technology, from a promotional strategy during the distribution process through to the use of virtual models. As such, collaboration using the various types of content has developed beyond simple integration of identities among various areas, integrated products or brands that as a new value.

Interdisciplinary research collaboration(IRC), reflected in 3,184 response of 1997 survey in Korea, is very common. IRC within same disciplines is 60%, and IRC with other disciplines is 40%. IRC with Humanities and Social Science is 11%. Policy expectations for interdisciplinary collaboration are very different depending on disciplines. The difference between disciplines and fields such as Natural Science, Life Science and Engineering is quite noticeable. Policies for interdisciplinary research collaboration are recommended to reflect the different tendencies between disciplines, at least between fields.

In this study, we focus on identifying the determinants of improving technology collaboration performance between buyer and supplier and the impact of the determinants on new product development performance. We adopted trust, control and information sharing as the determinants of technology collaboration and the frequency of new product introduction and ratio of new product on revenue as dependent variables. We conducted hierarchical regression and mediation analysis using the data collected from 600 Korean manufacturing firms by Korean Productivity Association and Ministry of Trade and Industry in 2012. The empirical findings indicate that trust, control and information sharing are positively associated with technology collaboration performance and the degree of technology collaboration is also positively associated with both new product development performance. In addition, new product development performance is not only affected by technology collaboration but also mediated by trust. This result implies that developing social capital, trust with partner play a important role in leading to better performance by open innovation.
