The purpose of this study was to explore how the number of network organizations, network continuity and service continuity of community child centers were affected by the charge factors, organizational factors and environmental factors of community child centers. To better understand this, we researched 107 community child centers in Chonbuk Province. The key results are as follows. The interpersonal connections of the charge factors had a strong effect on the number of network organizations, but organizational factors and environmental factors appeared to have no effect on the number of network organizations. The operational type(religious group), organizational support level of the organizational factors and public-private cooperation, regular consultative group operation(no) of the environmental factors appeared to have an effect on the level of network continuity. The region(local), regular consultative group operation(yes) and public-private cooperation of the environmental factors appeared to have an effect on the level of service continuity. It was hoped that the results would enable us to explore how factors related to a network had an effect on the service continuity, the number of network organizations and clients referral network continuity, and they appeared to have an effect on the service continuity.

S. M. Saperstone and M. Nishihama [6] had showed both continuity and stability of the orbital and limit set maps, K(x) and L(x), where K and L are considered as maps from X to $2^X$. The main purpose of this paper is to extend continuity and stability for dynamical systems to general dynamical systems.

We consider the relationship between absolute continuity for functions of a real variable and absolute continuity of functions of generalized bounded variation. Here, we obtain necessary and sufficient conditions between these two functions.

For a set $X{\subset}{\mathbb{Z}}^n$ let $(X,\;T^n_X)$ be the subspace of the Khalimsky n-dimensional space $({\mathbb{Z}}^n,\;T^n)$, $n{\in}N$. Considering a k-adjacency of $(X,\;T^n_X)$, we use the notation $(X,\;k,\;T^n_X)$. In this paper for a map $$f:(X,\;k,\;T^n_X){\rightarrow}(Y,\;2\;T_Y)$$, we find the condition that weak (k, 2)-continuity of the map f implies strong (k, 2)-continuity of f.

본 연구는 함수의 연속성에 대한 학문수학의 개념과 학생들의 인식의 차이를 탐구하기 위해, 아리스토텔레스의 연속 개념 및 함수의 연속성의 역사적 발달과정을 고찰하였다. 연속의 본질을 찾고자 했던 아리스토텔레스는 연속을 '분할 불가능한 하나의 전체'로 특징지었다. 19세기 이전 수학자들은 공간에 기초하여 함수의 연속성을 생각하였지만, 19세기 해석학의 산술화 이후 연속 개념은 현대적인 ${\epsilon}-{\delta}$ 정의로 나타났으며, 여러 학자들은 이 과정을 혁명적이라고 생각하였다. 학생들은 아리스토텔레스의 연속 개념 및 산술화 이전 수학자들과 유사한 관점으로 함수의 연속성을 생각하는 경향이 있었으며, 따라서 학생들의 개념을 단순히 오류로 보는 것은 무리가 있다. 함수의 연속성에 대한 본 연구는, 학생들의 오개념으로 인지되고 있는 것들은 때때로 오류라기보다는 역사적으로 존재해왔던 하나의 패러다임적 사고로서 볼 수 있음을 고찰하였다.

In this paper, the effects of earth continuity conductor are deeply analyzed for reducing the level of induced sheath voltage at the single point bonded sections. The various installation conditions of an earth continuity conductor are considered including conductor dimensions, its spacing from the three phase cables, and utilization of two earth continuity conductors when the grounding fault occurs on real power cable systems. Finally, the transient characteristics including reduction effects of induced sheath voltage are proved by EMTP simulations. The optimal installation condition of earth continuity conductor is also proposed based on those results.

It is concerned with the continuity of the Hardy-Little wood maximal function between the classical Lebesgue spaces or the Orlicz spaces. A new approach to the continuity of the Hardy-Littlewood maximal function is presented through the observation that the continuity is closely related to the existence of solutions for a certain type of first order ordinary differential equations. It is applied to verify the continuity of the Hardy-Littlewood maximal function from $L^p({\mathbb{R}}^n)$ to $L^q({\mathbb{R}}^n)$ for 1 ${\leq}$ q < p < ${\infty}$.

We introduce the notion of R($g$, $g^{\prime}$)-continuity on generalized topological spaces, which is a strong form of ($g$, $g^{\prime}$)-continuity. We investigate some properties and relationships among R($g$, $g^{\prime}$)-continuity, ($g$, $g^{\prime}$)-continuity and some strong forms of ($g$, $g^{\prime}$)-continuity.
