Previous studies have examined the relationship between corporate social responsibility and corporate's business performance (especially, consumers' corporate evaluation). According to them, the corporate social responsibility influences the consumers' corporate evaluation. A small and medium sized company as well as a large company is asked to conduct socially responsible actions, however, it is not easy to find a study that focuses on whether the effect of the corporate social responsibility on the consumers' corporate evaluation is different by the size of company. In this paper, we classified the corporate social responsibility into the four dimensions (economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility), and investigate the differences between a small and medium sized company and a large company in the effects of the four dimensions on the consumers' corporate evaluation. We showed that the each dimension of the corporate social responsibility had an positive effect on the corporate image regardless of the size of company. In addition, we demonstrated that the effects of the four dimensions on the company image were different by the size of company; The legal responsibility and ethical responsibility are more influential to the corporate image of a large company than to that of a small and medium sized company, however, the effects of economic responsibility and philanthropic responsibility are not different by the size of company.

Quality management has been applied to the industry for strengthening the competitiveness regardless of the size of company. However, it has been argued that the operational models for quality management used in the large-sized enterprise could not be applied to the small & medium-sized enterprise (SME) directly. This paper analyzes the states and outcomes of movements for quality innovation in the SME and tries to give some suggestions for improving and spreading the movements within the framework of the cooperation with the large sized company. Survey results show that the preferable quality movements depends on the size of company. Especially, the Single PPM movement is most preferable in the SME. It contributes th decreasing the fraction defective and to vitalizing the communication and cooperation between large-sized company and SME.

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.

Circular shareholdings among three companies are formed when company A owns stock in company B, company B owns stock in company C, and company C owns stock in company A. Since circular shareholdings among large family-controlled firms are used to give the controlling shareholder greater control or more opportunities to expropriate minority investors, the government has encouraged large business groups to gradually remove their circular shareholdings. In this paper, we propose a combinatorial optimization model that can answer the question, which equity investments among complicated investment relationships of one large business group should be removed to resolve its circular shareholdings. To the best knowledge of the authors, our research is the first one that has approached the circular shareholding problem in respect of management science. The proposed combinatorial optimization model are formulated into integer programming problem and applied to some Korean major business groups.

Purpose: This study aims to investigate the cross-sectional association of company size and self-rated health using representative data on Korean workers. Methods: We used the data from 2,884 wage workers collected by Korean Labor and Income Panel Study (17th). The association between company size and self-rated health was analyzed using logistic regression with covariates including demographic characteristics, work environment, job satisfaction, and health-related behaviors. Resulst: Odds ratio (OR) for better health status among workers in large-sized company was 1.351 (CI. 1.054~1.731), compared to workers in small-sized company. We performed three separate models stratified by firm size (small, medium, and large companies). Occupation variables showed different effect on health depending on firm sizes. OR for better health of white-color job (referred to blue-color job) was 1.693 in medium-sized company model but it was 0.615 in large company model. OR for better health of the workers working shift work showed 0.606 in large company model but it was not significant in small and medium company models. Conclusion: We found that small-sized company workers have significantly poor self-rated health compared to large-sized firm workers. This study revealed that there exist differences among health related factors depending on firm sizes.

Purpose - The purpose of this paper analyzes the relationship between the Corporate Social Responsibility(CSR) and Corporate Value to estimate whether the characteristics of Firm can change this relationship. Design/methodology/approach - This paper utilizes the total 776 firms' data over the period 2014-2018, and develops a new ESG index which was estimated by PCA. Findings - First, the estimated ESG index implies that Large company has the highest value of CSR, while Medium sized and Small company have the relatively low one. And comparing to the case of 2014, the trend of ESG index in Large company does not decrease in 2018. Second, there is a clear and significant non linear relationship between CSR and corporate value, it implies that the U-shaped exists in the Korean Firms. Such a tendency is mush stronger in the Large company. Third, the new ESG index indicates that it takes more time to increase Firm value in the Medium sized and Small company while there is a high possibility of increasing value in Large company from the little gab between the threshold points and mean value of ESG. Research implications or Originality - The non linear tendency between the Corporate Social Responsibility and Corporate Value is strongly affected by Firm size and the relative high quintile of ESG, but it is less affected by Firm history.

The aim of this study is to analyze the effect of the growing activities of large purchasing enterprises on the trust of small and medium size contractors, which is mediated by 'purchase accompany activity'. This subject study includes the first and second contractor companies in Korea. The results of this study are as follow. First, the knowledge and cost price sharing activities of major purchase vendor with cooperative company had a positive effect on the trust of cooperative company, however this was not so with the information sharing activities in that case. Second, the trust of contractors on large purchasing enterprises was positively influenced by sharing activities with purchasing activities of major company. Third, the knowledge and cost price sharing activities of purchasing enterprise with contractors on the sharing activities were mediated by the trust of contracting company on the large purchase enterprise. According to this study, the mediated effect of trust relationship can influence a contracting company. Whereas preceding studies of sharing activities were conducted about unidirectional instruct of large purchase enterprises to small and medium size contracting companies, this study was conducted on bidirectional effects, which included knowledge, cost price, information sharing activities between contracting companies and large purchasing enterprises. Conclusively, this study showed the possibility of spreading cognitive and change about mutual benefits strategy between small and medium size contracting company and large purchasing enterprise.

If the vibration is occurred in a large-sized bus roof, it makes people annoying and complaining the quality of a large-sized bus. So in design stage, it must be considered. To assess vibration at the roof which is equipped with air conditioner in design stage, finite element model is constructed. Computer simulation analysis and experimental method are performed. The dynamic characteristics of the large-sized bus are found by using eigenvalue method. It is related with dynamic behavior. The running conditions of a large-sized bus are velocity and road condition which followed experimental conditions. And the frequency response of a large-sized bus is well correlated with analysis result. Modal participation method is used for finding major modes at each peak. Using this method, we found that front and rear suspension system, engine mounting system and roof structure are the major reasons of the roof vibration. To reduce vibration level of roof in a large-sized bus, spring stiffness of front and rear suspension system, spring stiffness of engine mounting system and roof structure are properly combined. From this study, the vibration characteristics of the roof structure of a large-sized bus can be to a satisfactory level.

The purpose of this paper is to find out the implications by studying the optimal mechanism for securing the supply chain competitiveness of manufacturing industries, especially steel-making company. To this end, this paper examined the case of affiliates of the representative global steel group in Korea. So far, research on corporate strategy has been mainly focused on the parent company of large group company, but this time, considering the strategic limitations and characteristics of affiliates of large group company, we will explore the mechanism of supply chain management on the basis of ser-M, and explore appropriate mechanisms for global steel makers and affiliates of large group company. As a result of this study, in affiliates of large group, parent company centered mechanism is easy to operate because many of the affiliates of large group companies are built by the needs of the parent company. Therefore, the mechanism that maximizes the controllable internal Resources from the affiliated companies' position appeared to be suitable. The study on ser-M based supply chain mechanism in this paper is meaningful in that it examines the mechanism focused on the case of supply chain management of global steel manufacturer. The significance can be found in the case study of affiliates. In addition, it is significant in that it is a case study of domestic representative large group affiliates.
