Purpose - This study expands the corporate social responsibility (CSR) model and concepts by adding to it the concepts of corporate identity and public existence responsibility. Then, this study examines the structural relationship between corporate identity and public existence responsibility. This study contributes to expanding CSR to give customers a different perspective from previous studies in that it specifically measures corporate public existence responsibility, corporate identity, and corporate value creation and investigates the structural relationship. Research design, data, and methodology - This study addresses specific research questions. First, it asks whether non-financial performance is a component of CSR; second, it asks if the improvement in the corporate image should be treated as its corporate identity; and third, it tries to expand CSR concepts from corporate citizenship and public market awareness to public existence responsibility. The research hypothesis is formulated to confirm the relationships among CSR, corporate value creation, corporate identity, and public existence responsibility. Result - This study confirms that CSR has a positive correlation with corporate value creation and that CSR has a relatively positive correlation with corporate identity and public existence responsibility. Additionally, it confirms a positive correlation between corporate identity and public existence responsibility. However, corporate identity and public existence responsibility do not have an effect on corporate value creation. However, the influence of public existence responsibility confirmed the influence of corporate value creation through corporate identity as a mediating variable. Conclusion - This study argues that CSR produces more general performance including both financial and non-financial performance. It also confirms that the goals and performance of CSR can substitute for corporate value creation from general performance. It further confirms that public existence responsibility includes market public awareness, corporate images, and corporate associations. It suggests that corporations should see themselves as having public existence responsibility. Further, they should devise strategies to build corporate identities that associate with corporate goals and visions. Finally, this study contributes to the expansion of perspectives on CSR theoretical concepts and goals of performance of the corporation throughout the corporate value creation process.

In this paper, by using the Leray-Schauder continuation theorem and Wirtinger-type inequalities, we establish the existence and uniqueness theorems for two-point boundary value problems of a certain class of fourth-order nonlinear differential equations.

In the manuscript, we concern with the existence of solutions of boundary value problems for fourth order nonlinear discrete systems. Some criteria for the existence of at least one nontrivial solution of the problem are obtained. The proof is mainly based upon the variational method and critical point theory. An example is presented to illustrate the main result.

본 연구는 광고 커뮤니케이션 관점에서 장애인모델 TV광고에 대해 기호학적으로 분석하였다. 그레마스 기호사각형의 특징에 따라 장애인모델 TV광고에 대한 소비가치의 흐름은 보호적 가치에서 비-보호적 가치, 존재적 가치, 비-존재적 가치 순으로 움직이고 다시 보호적 가치로 ${\infty}$과 같은 형태로 이동하게 된다. 기호학적인 관점에서 네 편의 장애인모델 TV광고를 분석한 결과, SK텔레콤 TV광고(휠체어 농구편)는 존재적 가치, 아이폰4의 TV광고(연인편)는 비-보호적 가치, 삼성증권 TV광고(캠페인편)는 보호적 가치, 그리고 쏘나타 자동차 TV광고(쏘나타 터처블 뮤직시트)는 비-존재적 가치로 분석되었다.

In this paper, we establish sufficient conditions for the existence and uniqueness of solutions to a general class of three-point boundary value problems for a coupled system of nonlinear fractional differential equations. The differential operator is taken in the Caputo fractional derivatives. By using Green's function, we transform the derivative systems into equivalent integral systems. The existence is based on Schauder fixed point theorem and contraction mapping principle. Finally, some examples are given to show the applicability of our results.

To evaluate existence value of green area through industrial area worker＇s consciousness estimation, result that achieve is as following. According as green area amount of green area decreases, assessment about existence value of green area decreased. Environment that industrial complex worker can work in agreeable psychology need to increase green area in some form to be formed. Existence of green area enhances conscious value about visual improvement effect such as good environment, seasons change, and green quantity, and is judged that green area is exerting positive effect to consciousness regarding environment improvement effect such as cooling sensation, wind control, and noise decrease.
