The results from the analysis of recent security breach cases of industrial control systems revealed that most of them were caused by the employees of a partner company who had been managing the control system. For this reason, the majority of the current company security management systems have been developed focusing on their performances. Despite such effort, many hacking attempts against a major company, public institution or financial institution are still attempted by the partner company or outsourced employees. Thus, the institutions or organizations that manage Industrial Control Systems (ICSs) associated with major national infrastructures involving traffic, water resources, energy, etc. are putting emphasis on their security management as the role of those partners is increasingly becoming important as outsourcing security task has become a common practice. However, in reality, it is also a fact that this is the point where security is most vulnerable and various security management plans have been continuously studied and proposed. A system that enhances the security level of a partner company with a Virtual Desktop Infrastructure (VDI) has been developed in this study through research on the past performances of partner companies stationed at various types of industrial control infrastructures and its performance outcomes were statistically compiled to propose an appropriate model for the current ICSs by comparing vulnerabilities, measures taken and their results before and after adopting the VDI.

Corporate reputation is a widely debated topic among academics and a crucial issue in the business world. However, previous research in this area has been scattered and fragmented, leaving room for further study, particularly in terms of reputation measurement methods. Factors such as sustainability reporting, governance attributes, and company characteristics have been linked to improved company reputation. However, there is limited research on the effects of these variables on the new methods of measuring reputation, especially in developing countries like Malaysia. Therefore, the current study developed a new measurement for reputation and aimed to examine the relationship between these variables and the new proxy of reputation. The current study collected secondary data from the company's annual report for two years period of study (i.e., 2018 and 2019) and employed content analysis. A period of two years was chosen and deemed ample to provide insightful findings of the effect of the variables associated with reputation disclosure. The results indicate that sustainability reporting, outside directors, company size, leverage, and profitability significantly impact corporate reputation. This finding suggests that Malaysian PLCs and other firms in developing countries must recognize sustainability reporting as part of their reputation management strategy that influences the company's reputation.

Objectives : To elucidate the transient effects on the risk of occupational injuries as acute events and establish so alternative proposal. Methods : The study population comprised a total of 302 workers randomly selected from applications for occupational injury compensation reported to the Inchon local labor office from January 1. 1999 to December 31. A case-crossover design, where each case serves its own control, was applied to this study. Through a telephone interview, workers provided useful data concerning five job related stressful events such as company transfer, work load change, overtime work, exchange duty, and work-part transfer. They were asked whether there were stressful events within a week of the occurrence of injury and the degree of stress. Exposure status from one year prior was used as control information. In the end, the data provided by 158 of selected persons was used for the analysis based on the quality of the data provided by the participants. A conditional logistic regression was used to discover the transient effects on the risk of occupational injuries as acute events. Results : The effects a company transfer and work load change on occupational injury was statistically significant on the risk of occupational Injuries as an acute event(RR=5.5, 95% CI=2.501-12.428; RR=3.1, 95% CI=1.963-5.017, respectively). Other stressful events were found to elevate the risk factor for the occurrence of occupational jujury, but were not significant. Conclusions : Our results suggested that transient stressful events elevated the risk factor for the occurrence of occupational injury.

In this paper, a two-stage and top-down approach of mid-term and long-term R&D planning of public corporation is proposed to incorporate some characteristics of public corporation and to overcome the complexity of the real world planning. Unlikely to R&D planning of private company, the total investiment size of public corporation is institutionally determined. A top-down approach is developed to adopt this feature. The proposed approach has two stages to overcome the complexity. In the first stage, we develop a plan for R&D area by adopting the business area and the public role of corporation. In the second stage, we develop the detailed plan within each area. The proposed approach is applied to develop the mid-term and long-term R&D plan of Korea Gas Corporation.

In spite of the interest related to the entrepreneurship, the problems related to the creation of companies by the public civils servant still remain unanswered and not unanimously identified. In fact, a central question arises in this respect: "which are the factors which encourage the public civils servant to launch out in the creation of their own company?" or "how can one explain the entrepreneurial intention of the public civils servant?". For this end, and after having reviewed the principal subjacent factors of the entrepreneurial intention as well as the central assumptions of our research task, we will devote the second part to the empirical validation of the explanatory factors of the entrepreneurial intention in the specific case of the Indian public civils servant while proposing some recommendations on the matter.

Variety of data have been opened or connected by several levels of government. In smart city initiatives, open data become the source of a new business model. This paper is to foster ways of public open data (POD) by analyzing the start-up company that utilizes POD. In order to fulfill it, this paper adapts the case study research. Findings say that POD has potential to validate and further enrich the platform business. But to find which types of public open data are most prevalent is insufficient. To do this, it is more needed that sophisticated and many cases should be examined. However, this paper shows that platform business by using POD could lead to reduce the cost and increase the benefits for both providers and customers. From the findings, this paper shows that public open data has an important role not only to boost new venture creations which are prevalent ways of smart city but also to foster different platforms enabling new value capture and creation according to development of internet of things based on ICT technology.
