  • We introduce and investigate the notions of super (g,g')-continuous functions and strongly $\theta$(g,g')-continuous functions on generalized topological spaces, which are strong forms of (g,g')-continuous functions. We also investigate relationships among such the functions, (g,g')-continuity and (${\delta},{\delta}'$)-continuity.

  • Let X and Y be Banach spaces and consider a linear operator $\theta : X \to Y$. The basic automatic continuity problem is to derive the continuity of $\theta$ from some prescribed algebraic conditions. For example, if $\theta : X \to Y$ is a linear operator intertwining with $T \in L(X)$ and $S \in L(Y)$, one may look for algebraic conditions on T and S which force $\theta$ to be continuous.

  • We introduce fuzzy semi-regular spaces. Furthermore, we investigate the relations among fuzzy super continuity, fuzzy $\delta$-continuity and fuzzy almost continuity in fuzzy topological spaces in view of the definition of Sostak. We study some properties between them.

  • The quasi-(${\theta}$, s)-continuity is a weakened form of the weak (${\theta}$, s)-continuity and equivalent to the weak quasi-continuity. The basic properties of those functions are investigated in concern with the other weakened continuous functions. It turns out that the open property of a function and the extremall disconnectedness of the spaces are crucial tools for the survey of these functions.

  • In [11] the feeble continuity is introduced and then the weak and strong forms of feeble(or, equivalently $\alpha$-continuity) continuity are studied. In this note, we introduce a type of function called a slightly $\alpha$-continuous function and study several properties of it

  • In this paper, we generally introduce some of the terminology of Yalvac [10] and Azad [4] in intuitionistic fuzzy topological spaces. In addition to the fundamental concepts of intuitionistic fuzzy sets, we emphasize the usefulness of the concepts of intuitionistic fuzzy points intuitionistic fuzzy elementhood. Mainly, this paper is devoted to the study of intuitionistic fuzzy topological spaces with specific attention to the weaker forms of fuzzy continuity.

  • Purpose - This study aims to examine the correlations between relationship benefits, quality, and continuity intention of community services. It further investigates the mediation effect of relationship quality operating on the association between relationship benefits and relationship continuity intention. Thus, this study will aim to elucidate the correlations between relationship benefits, quality and community services intention. Research design, data, and methodology - To achieve these objectives, this study executed a questionnaire from the users of the child․adolescent psychological support service which represents part of community services. The research framework that was utilized in this study was of three main factors. They were relationship quality, relationship benefits, and intention of relationship continuity. In relationship quality, factors such as trust and commitment was included in this section. For relationship benefits, factors such as society benefits and commitment benefits were the essence. The control variable in this study was gender, age, income, hours of service used, and the number of times service was used in community services. Results - The key research findings are as follows. First, this study found out that the more the social benefits was enhanced in the community services, the higher the relationship continuity intention was. Second, this study has found out that the higher the trust of community services, the higher the relationship continuity intention. Third, this study has shown that the more the relationship benefits was enhanced in the community services, the higher the recognition by the users' relationship quality was. Fourth, the trust in the community services played a mediating role between the relationship benefits and relationship continuity intention. Conclusions - Many associations could be discovered on the correlations between relationship benefits, quality, and community service continuality intention. These results will have important implications for the future of child and adolescent psychological support services. In terms of relationship marketing, the three factors; benefits, quality, and continuity intention in community services were proved to be pivotal. In order for the continuity intention in community services, the two factors of benefits and quality were the influential factors. From a policy maker's standpoint, the relationship continuity was the most important factor.

  • Purpose: This study aimed to utilize concept analysis to obtain a better understanding of the concept of "continuity of care" in chronic diseases. Methods: The concept of continuity of care was analyzed using the Walker and Avant method. Covering literature in English from 1930 to 2018, the data sources included CINAHL Complete, Academic Search Complete, MEDLINE, PsyARTICLES, Health Source: Nursing/Academic Edition, Google Scholar, Science Direct, and the Cochrane Library. Results: A comprehensive definition of concept of continuity of care was developed based on a systematic search and synthesis. The key defining attributes were identified as (a) care over time, (b) the relationship between an individual patient and a care team, (c) information transfer, (d) coordination, and (e) meeting changing needs. The antecedents of continuity of care were having a chronic disease, inexperienced with disease management, a poorly coordinated healthcare system, and medical care limitations. The consequences of continuity of care were decreasing hospital admissions, reducing costs, reducing emergency room visits, improving the quality of life, improving patient satisfaction, and delivering good healthcare. Conclusion: The thorough concept analysis provides insight into the nature of "continuity of care" in chronic diseases and also helps ground the concept in healthcare.

  • 연구목적: 지자체는 국민의 안전과 생활에 직접적으로 영향을 주는 행정조직으로서 재난 발생 시 핵심 기능의 연속성 확보가 중요하다. 본 논문은 재난으로부터 지자체 핵심기능을 보호·유지하기 위한 기능연속성계획의 수립 및 실행력 확보를 위한 효율적인 방법을 검토하는 것을 목적으로 한다. 연구방법: ISO22301기반 한 기능연속성계획의 비효율성을 개선하기 위하여, 조직중심의 기능연속성 방법을 적용하여 계획수립 방안과 핵심기능, 소요자원 그리고 교육훈련에 관련된 기본 서식을 제시하고, 지자체에 적용하여 타당성을 검토한다. 연구결과: 제안된 조직중심의 기능연속성계획 작성 방법은 관료적인 지자체의 특성을 반영하여 실국 단위로 작성함으로써 작성 및 실무적용이 용이하다. 결론:민간에 비하여 업무가 조직중심으로 되어 있는 공공분야에서는 기능연속성계획 수립에 조직적인 관점을 충분히 반영하는 것이 더 효율적인 방법이 될 수 있다.

  • In the paper of Johnson[4], the results about continuity of homomorphisms were applied to those of generalized homomorphisms. This paper presents the results helpful to prove the continuity of generalized homomorphisms on Banach algebra and the continuity of generalized homomorphisms on it.
