Recently, the potential of advanced studies is being highlighted that the networking activity of entrepreneurs of venture businesses influences successful foundation. Given this background, this study intends to make an exploratory study on the influence of self-efficacy of the entrepreneur's cognitive characteristic and patience with ambiguity of the psychological characteristic upon networking activity, and the components of networking activity upon entrepreneurial performance. It was tested with sample of responses to the questionnaires for 156 entrepreneurs of venture businesses which are under 3 years since they were founded. Findings of this study are as follows: First, the entrepreneur's self-efficacy was shown to have a significant effect on networking and entrepreneurial performance. Second, patience with ambiguity was shown not to have a significant effect on networking and entrepreneurial performance. Third, networking was shown to have an effect on entrepreneurial performance, and among the components of networking activity, network frequency and reliability were shown to significantly influence entrepreneurial performance, while network range was shown not to have a significant effect on it. Therefore, for performance improvement of start-up enterprises, rather self-efficacy of the entrepreneur's cognitive characteristic than the psychological characteristic seems more important. Also, with a practical suggestion that for the networking activity of entrepreneurs of venture businesses, network frequency and reliability may have a more critical effect rather on entrepreneurial performance than network range, the limitation and direction of this study are presented.

Purpose: In this paper, we provide an illustration of Indonesian youth Social Networking Service (SNS) behavior and its relation to their culinary activity. Specifically, their behavior of culinary activity preferences and also the factors affecting their action of spending their money. Data and methodology: We gathered primary data from stratified random questionnaire survey (406 youth). The gathered data was analyzed using text data mining and statistics using R statistical computing language. Results: 1) We found out why our respondents are interested in following the accounts of SNS food influencers: i.e. visually attracted to the posts, as their reference to find places to dine out, as their reference to try new food menu and to get nostalgic feeling about the food. 2) The respondents decide to actually go to the recommended culinary places because of several factors, specifically, its description (visual and text), location, word of mouth (WoM), the experience of being to that place and price. 3) Important factors affecting culinary spent are income, number of following food influencer account, SNS usage time and their interest when looking at WoM. Conclusions: SNS behavior influences Indonesian youth culinary activity preferences and spent.

The Internet and all of its possibilities and applications have changed individuals' lifestyles in relation to socializing, working, and how they spend their leisure time. Social networking sites (SNSs), such as Facebook or Instagram, are ideal settings for interacting with others but, unfortunately, they are also ideal settings for motivated offenders to commit cybercrimes. Thus SNS users may be more vulnerable to cybercrime. The purpose of this study is to investigate the occurrence of cybercrime victimization, specifically cyber-harassment, cyber-impersonation, and hacking. Self-report surveys collected from a sample of 147 respondents were examined using the moderated multiple regression analysis and a logistic regression analysis to determine possible relationships between SNS lifestyle exposure activities and cybercrime victimization. The results indicate moderate support for the application of lifestyle-routine activity theory (LRAT) to cybercrime victimization. Possible educational and managerial implications, as well as suggestions for future research, are discussed.

The objective of this study is to examine the relationship between attitude in digital usage and life satisfaction level of the middle-aged people and older adults, and to analyze Sequential Mediation Effects of online networking activity and information producing and sharing in the online context. To achieve the main objectives, we conducted Hayeys'(2013) Process for SPSS Macro. The followings are the results of the study: First, there is a strong relationship between the attitude towards digital usage and the life satisfaction. Second, the results showed that impact of attitude in digital usage on life satisfaction among the older people is 0.291 unit higher, when they are engaged both in online networking activity and digital information production/sharing activities compared to involved in online networking activity alone. The results of the study is meaningful in that they can be used as a baseline data for reconsideration of digital usage and life satisfaction of the older adults, by providing comprehensive examination of relationship among attitude in digital usage, life satisfaction, online network activities, and digital information production·sharing activities of the older adults.

A new chromone analogue (1) was isolated from an EtOAc-extract of Pleosporales sp. culture medium, together with five known chromones (2 - 6). The isolation workflow was guided by a Molecular Networking-based dereplication strategy. The chemical structure of the new compound was elucidated using NMR and MS spectroscopy, and the absolute configuration was established by the Mosher's method. All isolated compounds were evaluated for their inhibitory effects on lipopolysaccharide-induced nitirc oxide production in RAW 264.7 macrophages. Compound 1 showed marginal inhibitory activity with an IC50 value of 118.7 μM.

Recently, emerging countries have been paying attention to Korean economic development policy, trying to adopt the Korean regional innovation model. Korea is also interested in exporting its regional innovation model and enhancing economic cooperation with those countries. This paper aims to analyze the capacity-building programs of the Korean regional innovation model for emerging countries and suggests policies for it. For this purpose, the local innovators' participation patterns in the process of collaborative learning/networking/interaction are investigated with a focused group-interview method. From an analysis of the programs supported by Korean organizations, this study finds that the correlation coefficient between the training time of capacity building and the participation rate of local members' collaborative learning is very high (0.975). Since the correlation coefficient between the participation rates of collaborative learning and networking is relatively low (0.667), a policy to link local collaborative learning to networking should be provided. As the correlation coefficient between the participation rates of networking and interaction is high (0.950), networking is a key to regional innovation. This study recommends activity programs to promote networking among local innovators, rather than training and consulting programs. As introduced in the Chungnam Techno Park case, this study suggests that the capacity-building program should include programs to initiate a collaborative learning network, to create a local-demand, regional innovation model, and to operate the regional innovation platform, which should be done by local innovators in the emerging countries.

This study examined the success factor of small business CEOs for continuous growth and development of business, and found it competencies of CEOs, and empirically studied the relationship between this factor and business performance. This study also focused on mediating effect of networking activity between competencies of small business CEOs and business performance. As a result of the study, it turned out that leadership competence, external cooperation competence and marketing competence have a significant effects on business performance. Small business CEOs' own efforts for increasing leadership, cooperation and marketing capability are needed as well as government policy and assistance in order to improve business performance. It also tested the mediating effect of networking activity to get information and resources, and proved it plays a role in enhancing business performance, so that it is necessary to promote small business CEOs' access to information and resources. Based on these empirical tests, government and supporting organizations need to refer to that factors affecting business performance are in priority supported in small business policy.
