This study conducted a fuzzy set qualitative comparative analysis study on culture and arts information portals to ensure practical and universal use and activation of culture and arts information portals. The capabilities and influence of affordances and system literacy according to user experience regarding accessibility to cultural arts information portals are as follows. First, physical affordances in the culture and arts information portal were key conditions for the culture and arts information portal user experience regarding system accessibility, system understandability, system usability, system usability, and system literacy. Second, the functional affordance of the user experience in the cultural arts information portal was relatively low and unimportant, and when the functional affordance was low, the user's system accessibility, system understanding, system usefulness, system usability, and system literacy were increased. Third, if the user's functional affordance and sensory affordance are low in the culture and arts information portal, the system accessibility, system understanding, system usability, and system literacy of the culture and arts information portal users are increased. Fourth, cultural arts information portals must build an innovative system with a systematic approach appropriate for the user base by linking system literacy capabilities with a focus on physical affordances.

이 연구는 뇌성마비 아동의 손 기능을 평가하기 위해 개발된 손 기능 분류 체계(Manual Ability Classification System: MACS)를 이용하여 경직형 뇌성마비 아동의 손 기능을 평가하고 손 기능과 기능적 수행도 평가인 일상생활활동평가(Functional Independence Measure of Children: WeeFIM), 대운동 기능 분류체계(Gross Motor Function Classification System: GMFCS)의 관계를 알아보고, 이를 통해 뇌성마비 아동의 손 기능 평가 체계로써의 MACS에 대한 기초의 자료를 제공하는데 그 목적이 있었다. 경직형 뇌성마비 아동 60명을 대상으로 아동의 손 기능과 대동작 기능, 일상생활활동을 평가하였다. 평가한 자료를 바탕으로, MACS와 WeeFIM 및 GMFCS와의 관계와 손 기능 수준에 따른 일상생활활동의 차이를 알아보았다. 그 결과, MACS와 GMFCS의 상관은 유의수준.05에서 유의한 것으로 나타났으며, 그 정도는 r =.659이었다. WeeFIM과의 상관을 알아본 결과에서도 총점과의 상관은 유의수준.05에서 유의한 것으로 나타났으며, 그 정도는 r = -.576이었다. 손 기능 분류 체계로 평가한 수준에 따른 일상생활 활용의 차이를 알아본 결과 유의한 차이가 있는 것으로 나타났다(p <.05). 뇌성마비 아동의 손 기능 평가 도구로써 MACS는 임상적으로 유용한 평가 체계로 사용될 수 있음을 알 수 있다.

This paper explores the ways in which the functions of local educational authority in Korea can be analyzed by systems thinking, and puts forward some policy leverage strategies to enhance predictability of education policy effects and also to prevent unanticipated side effects arising from it. In dong so, we sketch causal diagrams to depict functional changes of local educational authority, based on before and after comparison, and attempt to derive policy intervention points to minimize unforseen reactions from the stake-holders concerned. These diagrams make it possible for educational policy-makers to capture the feedback, stocks and flows, time delays, and non-linearities they identify, although they have some limitations. This paper concludes that newly-designed functions and structures for local educational authority may be accepted by the stake-holders including teachers and unions, only if complex systems surrounding functional changes regarding local educational authority can be clearly understood and relevant policy measures can be effectively taken before the functional changes happen.

Objectives : The aims of this study were to evaluate the diagnostic values of tongue coating thickness and sterno-costal angle as the quantitative diagnostic indicators in functional dyspepsia. Methods : We surveyed 60 functional dyspepsia patients recruited by the clinical trial, 'Clinical Trial for Evaluation on Availability of tongue diagnosis system (CTS-1000) : a Pilot study'. The patients were classified into three groups according to Rome III criteria for functional dyspepsia, and categorized into five groups according to Instrument of pattern identification for functional dyspepsia. Nepean dyspepsia index-Korean version (NDI-K) score, tongue coating thickness (percentage of tongue coating by tongue diagnosis system (CTS-1000), and weight of tongue coating by microbalance), sterno-costal angle, duration of illness and body mass index (BMI) were investigated. Results : Among the 5 types by instrument of pattern identification for functional dyspepsia, a significant difference of percentage of tongue coating was found. Percentage of tongue coating and weight of tongue coating showed significant correlation with total NDI-K score. Sterno-costal angle showed strong positive correlation with BMI and also showed significant difference between the non-overweight (BMI<23, n=32) and overweight ($BMI{\geq}23$, n=28) groups. Conclusions : Tongue coating thickness showed its potential as a new quantitative diagnostic indicator of functional dyspepsia. Further studies on the sterno-costal angle are anticipated to evaluate its potential as a new quantitative diagnostic indicator.

1. Standard and regulations for functional food evaluation cases form overseas (1) Japan For food function indication, Food Nutrition Improvement Act was amended in September 1991 and they managed functional food after setting specific health food in one of classification of special functional foods. For manification of raw material usage, the classification of health functional foods was performed by their application on: the control of internal organ status, cholesterol, blood pressure, mineral absorption, and prevention of dental caries.

This paper is concerned with properties of a Lyapunov functional of state delay systems. It is shown that if a state delay system has a pure imaginary pole for some state delay, then no Lyapunov functional satisfying a Lyapunov condition exists periodically with respect to change of the state delay. This periodic property is unique in state delay systems and has been well known in the frequency domain stability conditions. However, in the time domain stability conditions using a Lyapunov functional, the periodic property is not known explicitly.

In this paper, a functional m-redundant system, which is me-fault tolerant, is defined based on the graph-theory. This system is designed to be t fault-diagnosable by comparing its unit's outcomes without additive test functions, and so, the system down for diagnosis is not needed. the diagnostic model for this system is presented and this effectively uses system's redundancy. It is shown that this model can be converted into Preparata's model. Thus, the diagnostic characteristics of a functional m-redundant system is analyzed by the methods originated by Preparata et al..

In this paper, we consider a discrete predator-prey system obtained from a continuous Beddington-DeAngelis type predator-prey system by using the method in [9]. In order to investigate dynamical behaviors of this discrete system, we find out all equilibrium points of the system and study their stability by using eigenvalues of a Jacobian matrix for each equilibrium points. In addition, we illustrate some numerical examples in order to substantiate theoretical results.

In this paper, we study the existence and the stability of equilibria of predator-prey models with Ivlev's functional response. We give a simple proof for the uniqueness of limit cycles of the predator-prey system. The existence and the stability at the origin and a boundary equilibrium point(including the positive equilibrium point) are also investigated.

Integration of CAM and CAM information is important in the CIM era. For a CIM system, the feature representation can be a solution to the integration of product model data. These are geometry feature, functional feature, and manufacturing feature in the feature context. This paper proposes a framework to integrate the configuration design method, parametric modeling and the feature modeling method. The concept of design unit which is one level higher than functional feature and parametric modeling concept with functional features have been proposed.
