본 연구는 고혈압전단계자들에 대한 지속적인 건 스트레치시 시간에 따른 생리학적 반응을 분석하여 정상혈압자와 고혈압전단계자에 대한 EPR의 한 요소인 기계적 수용기가 혈압 및 혈역학 반응에 어떠한 영향을 주는지를 검토하였다. 그 결과, 안정 시와 시간에 따른 혈압 반응은 고혈압전단계자에 있어 SBP, MAP가 평균 20sec에서 통계적으로 가장 높은 경향을 보였으며(p<0.05), 정상혈압자에서는 SBP, DBP, MAP가 평균 45sec에서 가장 높은 경향을 보였다(p<0.05). 이는 고혈압 전단계자의 지속적인 수동적 건 스트레치 시 정상혈압자에 비해 Group Ⅲ mechanoreceptors의 역기능에 따른 상승된 혈압 반응이 초기에 나타내었다고 사료된다. 또한 혈역학 반응에서 안정 시와 비교하여 지속적인 수동적건 스트레치 시 고혈압전단계자에서의 HR, SV, CO, TPR 모두 유의한 차이를 보이지 않았으나 정상혈압자에서 SV, CO가 통계적으로 유의한 차이를 보였다(p<0.05). 이는 CO, SV, HR, TPR이 정상혈압자에 비해 고혈압전단계자에 있어 높은 경향을 나타내었지만, 혈역학 반응은 본 연구를 통해 차이를 보이지 않아 앞으로 연구가 필요할 것으로 사료된다. The purpose of this study was to investigate whether group Ⅲ muscle afferents play an important role eliciting abnormal blood pressure response mediated during passive muscle stretch in prehypertensive individuals. Eleven middle-aged prehypertensive men (average BP 133/80 ㎜Hg) and nine middle-aged normotensive men (average BP 119/74 ㎜Hg) participated in this study. After 1 min rest baseline data collection, the subject’s foot was flexed (dorsiflexion) by an automated cybex for one minute. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), heart rate, stroke volume, cardiac output, and total peripheral resistance were continuously measured on a beat-by-beat basis from a finger via a Finapres device for 1 minute. To evaluate the role of mechanoreflex, a component of exercise pressor reflex, SBP, DBP, and MAP responses over the course of time were examined. The results showed that the pressor response mediated by the muscle mechanoreflex was faster in prehypertensive individuals compared to the normotensive individuals. The substantial pressor response was observed within mean 20 sec of the onset of passive stretch in prehypertension, while mean 45 sec in normotension (p<0.05). It is concluded that excessive pressor response produced during exercise in prehypertension may be due to the dysfunction of the mechano-receptors.

It provides secured voice / video calls in conjunction with VoIP exchanges and supports differential services such as multi-party calls and command functions. In this paper, improving methods have been proposed to reduce power supply defects in the field of multi-functional VoIP phones. The power supply part was improved by applying TVS of the output voltage inlet of the dedicated adapter of the multi-functional VoIP phone, TVS of the PoE module input, adding blocking diodes, and adding DC / DC converters behind the poly-switch. Also, functional and environmental tests were performed to verify the validity of the proposed methods.

하나님 나라를 지향하는 지역교회의 코이노니아(Koinonia) 형성을 위한 교육

박화경(Hwa-Kyung Park) 한국기독교교육정보학회 2016 기독교교육정보 Vol.0 No.51

이 논문은 하나님 나라가 하나님과 사람과 창조세계 사이에 완벽한 코이노니아(Koinonia)가 이루어지는 곳이기 때문에 지역교회는 하나님 나라에 상응하는 코이노니아를 세상 속에 드러냄으로 교회와 세상이 가야할 길을 제시하고, 하나님 나라의 표지판이 되어야 한다고 주장하면서 코이노니아 형성을 위한 교육의 방향을 모색하였다. 이를 위해 먼저, 하나님 나라를 지향하는 지역교회 코이노니아의 신학적 근거를 몰트만의 삼위일체론에 근거하여 페리코레시스(Perichoresis)적인 삼위일체 하나님의 코이노니아를 제시하였다. 그리고 하나님의 코이노니아에 상응하는 지역교회 코이노니아가 갖추어야 할 특징을 분석하였다. 그리고 난 뒤에 하나님 나라의 코이노니아의 모습이 비교적 잘 나타나고 있는 세 교회를 선정하여 그 교회 코이노니아의 특징을 설명하였다. 마지막으로 하나님 나라를 지향하는 지역교회 코이노니아 형성을 위한 교육을 교육목적, 영역, 방법, 그리고 리더십으로 나누어 제시하였다. This is to study the directions of Christian education for forming Koinonia, insisting that local churches expose Koinonia reflecting God’s kingdom into the world as its post and that they show the ways working with society together. It is because the fact that God’s kingdom is the very place that the integral Koinonia among God, human beings and creatures is to be accomplished. To deal with it, first of all, here I have suggested the theological basis of local churches’ Koinonia, i.e., the Koinonia of trinitarian God perichoresisly based upon Moltmann’s Trinitarianism. Then I have analyzed the features of local churches’ Koinonia reflecting God’s Koinonia. Finally I have suggested the purpose, scopes, methods and leadership to form the local churches’ Koinonia towards God’s Kingdom.

The purpose of this study was to develop and implement a teacher training program to operate a competency based ‘Introduction to Intellectual Property’ curriculum and to verify the effectiveness of the training program. In order to accomplish the purpose of the study, we developed a teacher training program according to the process of ADDIE model of Instructional Systems Design based on the results of previous studies, in which they suggest to analyze the needs of teachers participating in the training, to organize the contents of training program considering the feasibility in the real teaching-learning fields, to operate the interesting and participatory program, and to consider the organization of teacher trainers. Questionnaires were conducted on the perception of subject relevance and perception of the importance and performance of the educational contents before and after the training. Through the importance - performance analysis (IPA), the research was able to confirm the effect and change of the training. The results of the study are as follows. First, there was no statistically significant difference in the perception of subject relevance in the pre - post test of the training. Second, as a result of analyzing the perception and change of the importance of educational contents, the trainees, who participated in the training recognized the importance of the whole educational contents of the ‘Introduction to Intellectual Property’, and the perception of importance was not changed after the training. Third, as a result of analyzing perceptions and changes in performance, performance was improved at a statistically significant level. Fourth, as a result of the pre - post test of importance - performance analysis of the trainees, the type of change of teachers participating in the training could be classified into four types such as ideal effect type, weak effect type, frustration type, and insincerity type. Based on the results of the study, the follow-up researches include the development of the teacher training program based on the teaching competency of the teacher in charge of the ‘Introduction to Intellectual Property’ curriculum, the establishment of systematic teaching and learning support system, and the construction of quality management of the teacher training program.

Purpose: We developed a multicriteria decision model to assist decision-makers in determining the optimal inspection intervals based on a set of competing criteria, such as cost, downtime, and availability. Methods: A procedure based on multiattribute utility theory is proposed for developing the model. The proposed approach can simultaneously determine the optimal inspection intervals for monitoring the failure behavior of systems trails to be inspected, maintainability features, and decision-maker preferences for cost, downtime, and availability. Results: We determined the optimal inspection intervals for periodic condition monitoring based on delay time analysis and a multicriteria framework. Conclusion: We developed a multicriteria decision model that includes cost, downtime, and availability for consequences that have multiple dimensions to be considered.

한국 여성의 정치자본에 관한 연구

박선경(Sun-Kyung Park) 서울행정학회 2007 한국사회와 행정연구 Vol.18 No.3

The purpose of this study is to examine the roles of NGOs over the formation of women's political capital in Korea. To inquire into the roles, various kinds of researches like books and articles regarding the subject are reviewed, to begin with, and a questionnaire survey is carried to 66 women politicians who have experienced in NGOs. And then, to analyze the questions, such research methodology as factor analysis and regression analysis are used. Several research findings found in this study are as follow: First, it appears that the women are likely to get the political capital by such factors as "conflict coordination", "citizen's education", and "protection of citizen's rights and interests". Second, among the political capital lessoned through participations at the NGOs' activities, political knowledge and attitudes they obtain as democratic citizens are relatively strong. Meanwhile, political skills learned from "linkage between individual and political system", "network building to articulate and aggregate individual interests" seem to be low its influences on the political capital. With political capital stored up, it seems very fortunate for the women to be able to access easily and effectively to political arena, and thereby, having an important effect on policy making. Therefore, this paper can say safely that as long as NGOs improve women's political capital, NGOs and their political capital can raise our democracy to higher status.
