Purpose This study attempted to predict corporate innovation and business performance using ensemble learning. Design/methodology/approach The ensemble techniques uses weak learning to create robust learning, which combines several weak models to derive improved performance. In this study, XGboost, LightGBM, and Catboost were used among ensemble techniques. It was compared and evaluated with traditional machine learning methods. Findings The summary of the research results is as follows. First, the type of innovation is expanding from technical innovation to non-technical areas. Second, it was confirmed that LightGBM performed best for radical innovation prediction, and XGboost performed best for incremental innovation prediction. Third, Catboost performed best for firm performance prediction. Although there was no significant difference in predictive power between ensemble techniques, we found that comparative analysis was necessary to confirm better prediction performance.

We report the results of a real-time synchrotron x-ray scattering study of the growth of TiN thin films on Si(001) substrates by RF sputtering. Our experiemnts show that the morphology of the TiN films strongly depends on growth conditions. After the nucleation and growth takes place with random crystallographic orientation at the very early stage, the films grow with a preferred orientation. Such preferred orientation was found to depend on both the sputtering power and the carrier gases used in the sputtering. Generally, the final morphology assumes either(111) or (002) crystallographic orientation. Using Ar sputtering, a cross-over effect from(002) to (111) was observed at intermediate time. The nature of the observed morphological changes is discussed.

Purpose - The purpose of this study is to discover how Korean expatriates that are currently employed in Korean subsidiaries operational in Malaysia possibly suffer from career dissatisfaction due to differences between Korean Corporate Culture (KCC) and Malaysian Corporate Culture (MCC). The integration of KCC into MCC is discussed. Research design, data, and methodology - The analysis herein is via a qualitative research. Forty-six interviewees voluntarily participated in in-depth interviews. Document analysis and qualitative interviews were utilized to develop participant profiles and to generate the framework. Interview data were transcribed and subsequently analysed to facilitate the development of themes and ultimately led to emerging patterns. The framework discusses the following Confucian pillars pronounced in KCC: Control Systems, Power Structures, Organisational Structures, Authority and Harmony and Stories and Myths. Those pillars are analysed and the results of the interviews are discussed in detail. Results - Korean expatriates on assignment in Malaysia endure struggles in all five selected Confucian pillars as they are not symmetrical with Korean Corporate Culture common at head companies in Korea. Conclusion - As a consequence, there is substantial disharmony which needs to be rectified if Korean companies are to continue their 'miraculous' economic movement into the country.

This study examines the effect of international capital flows on corporate capital structures in Vietnam by analyzing panel data from all non-financial listed firms from 2005 to 2014 using pooled ordinary least square (OLS) with a variance estimator. The analysis includes a comparison of the signs and significance of the variable coefficients from the perking order and static trade-off theories to the empirical results to determine the optimum approach to the corporate capital structure given Vietnam's high-inflation environment. The results indicate that international capital flows have a positive relation to the debt ratio in the long term, and the relationship is more robust for 2005-2009 than for 2010-2014. Corporate capital structures adjusted to changes in the business environment in different sub-periods (2005-2009 and 2010-2014). When the economic environment became more favorable, the pecking order theory's predictive power increased, and that of trade-off theory lessened. Manufacturing and non-manufacturing firms required different capital structure decisions to fuel their operations and grow under foreign competition. The analysis demonstrates that firms should intensify their use of long-term debt relative to the availability of capital, which is an implication not only for firms in particular but also for industrial innovation overall.

This research is mainly aimed at finding out about the effects of the safety and health management system on corporate performance through systematic operation by efficiently allocating material and human resources within the company by participating all employees and stakeholders in order to prevent and maintain industrial accidents and the optimal working environment, and how to maintain and activate the safety and health management system at the center of electric contractors.The analysis results are as follows. First, management, organizational management and resource preparation will have a positive impact on the management capability of the electric power corporation. It was assessed that the more well-transmitted and understood within the organization, the better the construction plan, the better the equipment management status, the more positively the management capability of electric works was to be achieved. Second, management, organizational management and resource preparation will have a positive impact on corporate management performance.This seems to have a positive effect on a company's business performance when the standards of OHSAS are met with construction plan and construction equipment management are high as related information such as industrial safety and health laws are strengthened and companies' safety and health activities, advanced safety and culture are released to facilitate organizational management.Third, the management ability of the electric power corporation will have a mediated effect on the effect of management, organization management and resource preparation on the performance of the enterprise. This means that the direct effect of the independent variable management organization on corporate management performance is .401 The indirect effect is .168.658 shows that the direct effect of resource preparation on corporate management performance is .423, the indirect effect is .178 and the total effect.It was analyzed at 643.

From the perspective of corporate governance, we examine the acquirers' performance of mergers and acquisitions. The empirical results of our study show that outside active shareholders, such as block shareholders or institutional shareholders, affect acquirers' performance in M&A's : the ownership of outside active shareholders is positively correlated with the performance of acquirers. However, the ownership of insiders, such as that of encumbent manners or major shareholders, does not have any significant effect on the performance of M&A's. We also found that the ownership of foreign investors increased its explanatory power after the financial crisis of Asia. Since the current literature concludes that the improvement of corporate governance would enhance the shareholders' wealth, the results of our study implies that outside active investors, rather than insiders, are playing an important role in the corporate governance.

Purpose: This study intends to review the risk assessment procedures specified in the corporate disaster management standard. Method: The requirements for each stage of risk assessment stipulated in the corporate disaster management standard were identified, the case of application of the organization'A' and the partner companies were reviewed, and the risk assessment procedure in line with the requirements was reviewed. Result: It was reviewed that it was necessary to clearly define the method and procedure for deriving risk scenarios, which are the requirements of the corporate disaster management standard, and to introduce a standardized procedure for deriving risk scenarios. Conclusion: A method of deriving risk scenarios was implemented by applying the STPA technique based on the system theory for power generation fuel supply and demand, and it was suggested that the STPA technique be reflected in corporate disaster management standards as a risk scenario derivation technique for the establishment of a disaster reduction activity plan.

This Article examines the regulation of outsider trading under the Financial Investment Services and Capital Markets Act (the "Capital Markets Act"). Outsider trading occurs when a market participant who is not a traditional corporate insider trades securities based on either "inside" or "outside" nonpublic information. Unlike "inside" information, "outside" information is referred to as information not derived directly or indirectly from the issuer. "Outside" information includes both "corporate" and "market" information. "Corporate information" is information about events or circumstances which affect the company's assets or earning power. "Outside corporate information" is information about the company's assets or earning power not derived directly or indirectly from the issuer. "Market information" is information about events or circumstances which affect the market for a company's securities but which do not affect the company's assets or earning power. The Capital Markets Act prohibits both "temporary insiders" from using "corporate" information in trading securities and "outsiders" from using "market" information, such as (i) information regarding the initiation or discontinuance of a tender offer; or (ii) information regarding acquisition or disposition of stocks in bulk. However, the Act does not encompass circumstances (i) where an outsider trades securities based on confidential corporate information obtained through certain types of wrongful conduct; (ii) where an outsider trades securities based on corporate information obtained through eavesdropping; and (iii) where an outsider trades securities based on either outside corporate information or market information created by the outsider himself. In order to plug a few of the gaps left open in the law of outsider trading under the Capital Markets Act, this Article suggests that regulators adopt a relatively broad reading of the scope of ${\S}$ 178(1) of the Act, which is similar to SEC Rule 10b-5, to include outsiders with no relationship to the corporation that had issued the securities. Since ${\S}$ 178(1) of the Act does not require "deception" for liability, it would seem to evade the limitations imposed by the U.S. misappropriation theory. Key Words : Outsider Trading, Insider Trading, Material Nonpublic Information, the Capital Markets Act, Misappropriation Theory, Fiduciary Theory.
