This study attempts to verify effects of CEO' supports, compensation and educational training and those of individual annual salaries and company's sales on promotion of knowledge management expected to contribute to enhancing construction industry's competitiveness, from the perspective of person-organization fit. For the analysis, a total of 368 effective questionnaires were used to conduct independent sample t-test, regression analysis and hierarchical moderated regression analysis. The findings show that individual annual salaries have a positive relationship with company's performance and company's sales also have positive relationships with both knowledge management activities and company performance, and CEO's supports, compensation and educational training are important factors that can improve knowledge management activities. In addition, the principle that the rich get richer and the poor get poorer is also operated in construction industry, as in other industries. Therefore, members in a company should conduct optimal strategies to enhance the knowledge management activities through selection and concentration, while governmental agencies require the establishment of IT system for it and supports for related cost and consulting of it.

A novel architecture and proprietary electronic inks were developed to provide disruptive digital-media solutions based on an electrokinetic technology platform. The flexible reflective electronic media (eMedia) was fabricated by imprinting three-dimensional microscale structures with a roll-to-roll manufacturing platform. The HP technologies enable the required attributes for eMedia, such as low power, transparency, print-quality color, continuous levels of gray, and lowcost scalability. Pixelation was also demonstrated by integrating with the prototype oxide thin-film transistor backplane, and the system architecture was further developed by stacking primary-colorant layers for color reflective-display application. The innovations described in this paper are currently being developed further for the eSkins, eSignage, and ePaper applications.

In this paper, the fault line selection and location problems of single line-to-ground (SLG) fault in distribution network are addressed. Firstly, the adaptive filtering property for empirical mode decomposition is formulated. Then in view of the different characteristics showed by the intrinsic mode functions(IMF) under different fault inception angles obtained by empirical mode decomposition, the sign of peak value about the low-frequency IMF and the capacitance transient energy is chosen as the fault line selection criteria according to the different proportion occupied by the low-frequency components. Finally, the fault location is determined based upon the comparison result with adjacent fault passage indicators' (FPI) waveform on the strength of the interaction between the distribution terminal unit(DTU) and the FPI. Moreover, the logic nodes regarding to fault line selection and location are newly expanded according to IEC61850, which also provides reference to acquaint the DTU or FPI's function and monitoring. The simulation results validate the effectiveness of the proposed fault line selection and location methods.

The objective of the study is to create color plan for company D based on color images of the Bloomsbury Group paintings, which is an art institute based in Bloomsbury, London, a hometown of the company, to renew the traditional brand image of the company by blending fashion and art. This study analyzed 'D's previous F/W Color planning from 2003 to 2007 through NCS to understand characteristics of company D's color planning. It considered company D's color renewal concept by looking into Bloomsbury Group's backgrounds and pieces. Based on 2008-2009 F/W color trend and the analysis result, the study suggests a color plan with reference to a case study of the company D, for which I work as a colorist. The color renewal of the company D for 2008-2009 F/W season was categorized into theme I. Bloomsbury and theme II. Charleston for planning. The following table summarizes the result of 2008-2009 F/W season color plan with focus on development of new check and print patterns. The significance of the study can be found in that it advanced beyond the color planning stage to be applied to the actual renewal.

The disclosure of corporate social responsibility (CSR) is an important part of the company. CSR disclosure (CSRD) is interesting to study because CSRD in the annual reports is very important in terms of attaining company objectives to satisfy the interests of stakeholders; protect employee's interests; clarify the extent of contribution of the company in both CSR activities and CSRD; assist appropriate investment decisions. This study examines the structure of share ownership and company size as determinants of CSRD in the banking industry. We use a quantitative approach in this approach, in which researchers start with hypotheses and then collect data that can be used to determine whether empirical evidence to support that hypothesis exists. The sampling technique used is purposive sampling so that the research sample was 14 banking companies that are listed on the Indonesian Capital Market Directory from 2015-2017. Data analysis techniques using multiple linear regression determined the relationship between research variables. The results of the study state that managerial ownership, institutional ownership, foreign ownership, and company size affect CSRD. This demonstrates that the role of managerial ownership, institutional ownership, and foreign ownership have an impact on CSRD and are deemed necessary for the corporate environment. Besides, company size determines the activities of CSRD so that it can increase public confidence in the company's operational activities.

State-Owned Enterprises (SOEs) are business entities that are owned mainly by the state. Good financial governance (GFG) is as important for SOEs as for the private sector companies. Prudence and GFG can affect the value of the company. This research aims to test the impact of macroeconomics, investment decisions, and financing decisions on prudence, Corporate Social Responsibility Disclosure (CSRD), dividend policy, and company value of SOEs registered on the IDX from 2014-2019. GFG and financing decisions are moderating variables. The population in this study is 16 SOEs listed on the Indonesia Stock Exchange from 2014-2019. The research method is quantitative and uses Partial Least Squares (PLS), which is an approach to Structural Equation Models (SEM) that allows researchers to analyze the relationships simultaneously. The results showed that macroeconomic factors, investment decisions, financing decisions, and prudence directly affect the company's value. However, CSRD and dividend policy directly do not affect the company's value. Prudence can mediate the influence of financing decisions on company value. GFG moderates the relationship between prudence and company value. Thus, GFG is key to producing compliant regulatory reports and disclosures. GFG aims at facilitating effective monitoring and efficient control of the business. Its essence lies in fairness and transparency in operations and enhanced disclosures for protecting the interest of different stakeholders.

This study investigates the company value determinant by observing the effect of financial performance and Corporate Social Responsibility (CSR) and its role in moderating performance achievement. The macro-economy variables such as inflation and interest rate are also used as the controlling variable. This research employs the sample of manufacturing companies of the food and beverage sub-sector listed on the Indonesia Stock Exchange. This study used panel data from 2013 to 2017, with the moderating regression analysis. The result shows that the profitability of the current or previous period affects the company's value. CSR and company size affect the company value at the next period shows that stock price, which reflects the investor's perception today, will be affected by the CSR, Size, and Return On Asset of the previous year. CSR also shows that it can be the substitute for profitability since a company that performs CSR is the one that has a good performance. The regression moderating model and the profitability of the previous period have a higher explanatory power than the higher R square value in explaining company value.

베트남은 풍부한 노동력과 성장 잠재력으로 한국 기업들의 투자대상국으로 관심이 높으며, 2011년 9월 현재 약 239억 달러를 투자하고 있어 최대 투자국으로 부상하고 있다. 또한 한국의 대 베트남 투자 패턴도 노동집약적 산업형태에서 고부가가치 형태로 전환하고 있다. 본 연구는 베트남의 직접투자에 따른 경쟁력 결정요인에 따른 투자성과를 분석하여 한국 투자기업의 경쟁력을 확보하는데 있다. 특히, 베트남 투자기업의 대내적인 요인인 기업규모, 마케팅기술, 재무관리, 국제경험, 조직관리 등과 현지 베트남 시장요인인 현지시장규모와 시장환경 등의 요인이 베트남 투자성과에 어떠한 영향을 미치고 있는가를 분석한다. 본 연구결과를 보면 "투자기업의 규모", "투자기업의 국제경험", "투자기업의 마케팅 기술", "현지국의 시장규모", 그리고 "현지국의 시장환경"이 한국기업의 투자성과에 유의한 정(+)의 영향을 미치고 있다. 그러나 "투자기업의 조직관리"와 "투자기업의 재무관리"는 베트남 투자성과에 유의한 영향을 미치지 않아, 가설이 기각되었다. 투자성과에 유의한 영향을 미치지 않았다고 해서 투자기업의 결정요인으로 중요하지 않은 요인은 아니라는 것이다. 그렇기 때문에 한국기업은 베트남에 지속적으로 투자를 하고 있다.

Purpose: The purpose of this study was to investigate the influences of job insecurity on job related depression and anxiety in large- and small-sized company employees. Methods: Data of the third Korean Working Condition Survey in 2011 were used. Subjects were 2,050 large-sized company employees and 18,924 small-sized company workers. $x^2$ test and multiple logistic regression using SAS 9.2 were conducted. Results: Large- and small-sized company employees showed significant differences in terms of demographic, health-related, and job-related characteristics. From the bivariate analysis, gender, income, self-rated health, occupation, working hours per week, job-related stress, workplace violence, and job insecurity were significantly related to job-related depression/anxiety in large-sized company employees. From the multivariate analysis, higher income (AOR: 0.22, 95%CI: 0.07~0.71), better health perception (AOR: 0.05, 95%CL: 0.01~0.18), 40 or more working hours per week (AOR: 0.20, 95%CI: 0.05~0.79) showed lower risk for job-related depression/anxiety. From the bivariate and multivariate analysis, better health perception (AOR: 0.32, 95%CI: 0.20~0.53), higher job-related stress (AOR: 2.57, 95%CI: 1.68~3.93, workplace violence experience (AOR: 4.26; 95%CI: 2.88~6.30), and job insecurity experience (AOR: 1.90, 95%CI: 1.18~3.05) were significantly related to job-related depression/anxiety in small-sized company employees. Conclusion: Results of this study suggest that job insecurity experience was significantly related to job-related depression/anxiety in small-sized company employees but not in large-sized company employees. Therefore, small-sized company workers who have experienced feeling of job insecurity are vulnerable population in terms of job-related depression/anxiety.
