Some Common Fixed Points for Type(β) Compatible Maps in an Intuitionistic Fuzzy Metric Space
박종서 한국지능시스템학회 2013 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.13 No.2
Previously, Park et al. [14] defined an intuitionistic fuzzy metric space and studied several fixed-point theories in this space. This paper provides definitions and describe the properties of type(β) compatible mappings,and prove some common fixed points for four self-mappings that are compatible with type(β)in an intuitionistic fuzzy metric space. This paper also presents an example of a common fixed point that satisfies the conditions of Theorem 4.1 in an intuitionistic fuzzy metric space.
Extension of a flow on a completely regular space
박종서 충청수학회 2019 충청수학회지 Vol.32 No.4
'Let $X$ be a completely regular space and let $\beta(X)$ be the Stone-\v{C}ech compactification of $X$. A flow $\phi$ on $X$ can be extended to a flow $\Phi$ on $\beta(X)$.

The term "Value Added" originated in the measurement of the national income in the economics, and has been since used in the measurement of corporate Social Contributions, Production analysis and Collective bargaining. This research therefore discusses the nature of value added, its measurement, and the Accounting of value Added. Value Added of any enterprise can be defined as the difference between the revenues received for the sale of it output and the casts which were incurred in producing that output. A) Value Added is one of the major Contributing factors to the national economic growths. B) Value Added is widely used as a measure of a firms growth and prosperty. The value added accounting is defined as a field of corporate accounting which is studying and accounting Value Added, economic value produced by the firm. Because value added accounting is practised as the enterprise theory of the firm, its team members are composed of employees, stockholders, creditors, and government. The value-added income includes all payments to stockholders in the form of dividends, taxes to governmental units and earings retained in the business. The total value-added concept also includes depreciation.

This study was pursued for the keypoint of the measuring of the Social Responsibility in the Accounting. Measuring the degree of observance of social responsibilities by industry is a very difficult task. The types of Social Responsibilities are multi-faced and variable. When Social Responsibility is measured non-monetary terms (quantity, quality, purity, consistency, number of men) the problem is particulary acute. The techniques for measuring Social Responsibility vary according to type of responsibility. There is need for a Standardized of Social Measurement. In order to increase objectivity and trust, as we've seen above, the need to establish a standard of measurement is absolute.
