This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

This study examines what changes and impacts have brought to the corporate cash holding after the financial crisis. The main findings can be summarized by two parts. First, the recent high increase in cash holding is only found in few companies, meaning that the level of the overall ratio has not risen. Second, Korean companies tend to have a higher ratio of cash holding when they have more uncertainty about their business performances. The higher the uncertainty in overall business performances also has some effects on the cash holding patterns of the Korean companies.

Recently, the systems for managing the labs provide services that can be managed in real time by using various sensors based on IoT. The system collects sensor data and transmits it to the server, identifies the dangerous situation, and sends operation commands to the devices. These systems have a centralized structure that slows data processing when managing multiple laboratories. To solve this problem, this paper proposes a system that manages laboratories in distributed processing environment to identify and manage risk situations. The sensor module is used to control the laboratory and to automatically identify and respond to the dangerous situation.

This paper addresses two main issues relevant to the structural assessment of buildings subjected to explosions. The first issue regards the robustness evaluation of steel frame structures: a procedure is provided for computing "robustness curves" and it is applied to a 20-storey steel frame building, describing the residual strength of the (blast) damaged structure under different local damage levels. The second issue regards the precise evaluation of blast pressures acting on structural elements using Computational Fluid Dynamic (CFD) techniques. This last aspect is treated with particular reference to gas explosions, focusing on some critical parameters (room congestion, failure of non-structural walls and ignition point location) which influence the development of the explosion. From the analyses, it can be deduced that, at least for the examined cases, the obtained robustness curves provide a suitable tool that can be used for risk management and assessment purposes. Moreover, the variation of relevant CFD analysis outcomes (e.g., pressure) due to the variation of the analysis parameters is found to be significant.

Purpose: The purpose of this study was to analyze the trend of research on clonorchis sinensis in Korea. Method: The study design was a literature analysis in which research studies with 'Clonorchis' in the title were collected from 2001 to 2007. A total of 115 research studies were analyzed based on the year of publication, study design, major or institute of researcher, study sample, and research theme. Results: 10-19% of the research studies were published each year from 2001 to 2007. Experimental study design was the most frequent at 54.8%. Medicine or parasitology as the major of researchers were 43.2% and 41.2% retrospectively, but no nursing studies were found. For study samples, 65.9% were cyst larvae and animals, followed by human beings (29.5%). In research theme, the structure and gene analysis of clonorchis sinensis was the most frequent (32.1%), followed by animal experimental studies (15.7%), epidemic studies of clonorchis sinensis prevalence and changes (13.0%), and methods of diagnosis of clonorchis sinensis and effectiveness (12.2%). Conclusion: Although positive rate of clonorchis sinensis is still high, intervention studies for managing clonorchis sinensis were not found. So, methodological research developing clonorchis sinensis management program and intervention study is needed for high risk groups in rural communities.

This study identifies the determinants of potential failure of Islamic Peer-to-Peer (P2P) lending in Indonesia, and the mediating effect of Islamic ethics on reducing the potential for failure of Islamic P2P lending. This study uses primary data retrieved through questionnaires from the perspective of 152 stakeholders in Islamic P2P lending. Using a structural equation model (SEM), the study found that indebtedness, financing size, and governance have positive and significant relationships with the potential failure of Islamic P2P lending. This study provides evidence that the customer's internal conditions and the governance structure applied can increase the potential failure of Islamic P2P lending. Further, Islamic ethics is evidently able to partially reduce the potential failure of Islamic P2P lending by lessening risk management exposure, but it fails to address failure through Ponzi scheme exposure. As an implication, this study suggest that Islamic P2P lending must implement Islamic ethics more comprehensively by optimizing the advisory and supervisory role of the shariah board within their overall boards of directors also in their operational activities. Finally, it also adds to the existing knowledge on financial technology literature, particularly on the determinants of potential failure of financial technology from the perspective of stakeholders.

While there exists voluminous literature on the internationalization of the firms, it has focused on mature firms or born-global firms. There is still a lack of research on firm that is in the growth stage between venture and mature firm. To fill this gap, this paper focuses on the newly public firm which is enter the stock market through initial public offerings (IPO). Specifically, I examine the relationship between the early listing and internationalization. In the venture firm aspect, the decision of the IPO necessary to allow to change organization structure, ownership and take a risk from environmental movements. This paper suggests early listing is a behavior of entrepreneur orientation. According to empirical results, there is a positive relationship between early listing and internationalization. It implies that early listing may help international expansion by sourcing finance, reputations from market. Furthermore, this study emphasizes the importance of financial slack resources to international expansion. I conclude that ventures need not only early entering in stock market but also securing sufficient financial slack resources to achieve sustainable growth in the international market.

Typically, General contractor in the construction industry can not plan their own of the amount of orders received, and because of the size of wide fluctuations in the amount of annual orders received for equipment or personnel to full-time employment has limits. Therefore, with a vertical division of labor between specialist trades which distributed the risk and the intention to improve the efficiency of production will be. For this reason, the production structure of the general subcontracting relationships are formed. In this way, Depending on the structure of production outsourced management of the project is the impact on the successful completion. Nevertheless, most construction companies do not achieve effective an organized cooperation until now. This study is to understand the actual conditions an organized cooperation between general contractor and specialist trades, and is look at ways to improve with find the complement. This paper is a preliminary study of the leading research based on the present condition of the cooperating companies considered to be the cause. A result of Analysis, the actual conditions in cooperation of the construction industry is staying in an external form of organizational cooperation And were not effective utilization of the organization for the cooperation a production. Specialist trades have had to register as partners for the amount of orders received, the level of practical cooperation was almost no activity to improve a production. in each step an organized cooperation in the construction industry, to improve productivity construction and to create of economic value for the cooperation of production is required.

In many cases, the construction industry in Korea has a hierarchical structure in which a general contractor in charge of the entire project is subcontracted from the client and entrusts the construction to a specialty contractor in charge of detailed work types. In this structure, the general contractor manages and takes responsibility for the entire construction, but the person directly involved in the construction is an individual specialty contractor, so the quality and safety of the facilities will vary according to their construction and management capabilities. In order to solve quality and safety problems that may arise due to the difference between the person receiving the order for construction and the person who actually constructs it, it is necessary to let the person who receives the order perform the construction directly for projects under a certain amount. The system introduced for this purpose is the direct construction mandatory system. As described above, although this system was introduced to prevent bad construction and risk transfer, it is a system that has various problems due to the characteristics of the domestic construction industry, institutional limitations, and practical problems, so it is necessary to improve it legally and institutionally.

Purpose: As communicable disease, COVID-19, pandemic strikes over the world, it is critically bewared that air travel possibly be a major pass way to deliver the infectious disease virus. Especially the airplane could be an unique environment to cultivate the virus spreaders. In order to keep the continuous safe airway as well as the industry, related international associations and organizations have been published the guidelines for the prevention and control the infectious disease through the all aspects of aviation. By reviewing the guidelines, focusing on the in-flight infection prevention and control, this study would not only inform a summary of the international guidelines but also provide an essential and general consideration for related research or guideline study. Methods: Guidelines of 5 major countries are reviewed, which has been seriously influenced by COVID-19 : U.S., Canada, E.U., Australia and China. The items of the guidelines are re-categorized as its similarity and structure by applicable cases. Results: The result of this study shows that each guideline seems to share a major structure and issue such as identifying sick traveler, sick passenger care, and cleaning even though that of China has a different since it used to consider the flight conditions based on 3 levels of infection risk. For sick passenger care, the guidelines includes crew safety, service level, sick passenger isolation, and cleaning. Implications: A published guideline as a public manual could be to prevent and control the in-flight infection efficiently and promptly. It also could provide a confidence of knowledge and educate for all users to prepare the in-flight emergency as well.
