Purpose: Ca2+ homeostasis plays an important role in myocardial cell injury induced by hypoxia-reoxygenation, and prevention of intracellular Ca2+ overload is key to cardioprotection. Even though thiopental is a frequently used anesthetic agent, little is known about its cardioprotective effects, particulary in association with Ca2+ homeostasis. We investigated whether thiopental protects cardiomyocytes against hypoxia-reoxygenation injury by regulating Ca2+homeostasis. Materials and Methods: Ne

The purpose of this study was to analyze a structure of multicultural education studies by using co-word analysis. Data were 4,695 keywords from 1,685 multicultural education studies. First, after refining, keywords that occurred more than 15 times were selected. Second, using the selected keywords, a co-occurrence matrix and cosine similarity matrix were made. Third, hierarchical cluster analysis and network analysis were conducted. Results of the study are as follows. First, 6 clusters were cl

이 연구의 목적은 동시출현단어분석 방법을 활용하여 다문화 가정 연구의 구조를 분석하는 것이다. 분석에 사용한 주제어는 982편의 논문에서 제시된 총 3,898개의 한국어 표기 주제어였다. 우선 데이터 정제를 거쳐 빈도 9이상 주제어 40개를 분석에 사용하였다. 그리고 선정한 40개 핵심어가 한 문헌 내 동시에 등장한 것을 이원 행렬로 작성하고, 이를 토대로 코사인 유사행렬을 작성하였다. 끝으로 주제어를 유사한 특성에 따른 집단으로 군집화하기 위해 코사인 유사행렬을 토대로 계층적 군집분석을 실시하였다. 분석 결과는 다음과 같다. 첫째, 거시적 차원 연구는 다문화 교육 정책(군집1)과 다문화 사회 정책(군집2)로 구성된다. 둘째, 미시적 차원 연구는 다문화 가정 구성원에 관한 것으로, 크게 다문화 가정 부모와 자녀에 대한 연구로 구분된다. 구체적으로 다문화 가정 부모의 개인/심리적 특성(군집3), 다문화 가정 자녀-영유아기(군집4), 다문화 가정 자녀-청소년기(군집 5), 다문화 가정

본 연구의 목적은 중학교 교사가 인식하는 생활지도의 핵심개념을 파악하는 것이다. 이를 위해, 먼저 “교사로서 생활지도를 어떤 내용으로 어떻게 하고 계십니까?”라는 초점질문을 가지고 13명의 중학교 교사를 대상으로 면담을 진행하였다. 면담자료는 언어네트워크 분석을 통해, 첫째, 핵심적인 주제어를 토대로 핵심개념을 파악하고, 둘째, 교직 경력 10년을 기준으로 구분한 두 집단의 핵심개념을 비교하였다. 연구결과, 생활지도의 핵심 개념은 1)관심, 대화, 상담을 통한 지도, 2)학생의 입장 인정 및 이해, 3)학생 성별에 따른 차별적 지도, 4)학부모와의 연계를 통한 지도와 같이 네 가지 핵심 개념을 도출할 수 있었다. 또한 교직 경력에 따른 두 집단의 차별적인 핵심개념을 토대로, 교직 경력에 따른 차별적 연수의 필요성에 대해 논의하였다.

The focus of this paper is to examine the network dynamics of market tie dissolution in the legal services industry. Based on a longitudinal dataset on top 250 U.S. law firms and their 200 large financial clients, this study analyzes the ways in which interpersonal and interorganizational networks affect the probability of buyer-seller tie break-up. The central thesis is that (inter-)organizational behavior must be properly conceptualized and analyzed within its relational context. Why, how, and

It has been reported that natural dyeing is impossible without pre-treatment with metal mordanting agents. However, pre-treatment with chitosan, which has high affinity to natural dyes, could result in an excellent dyeing with various natural dyes.In this study, three treatment methods were employed;1) Using PET without any pre-treatment (Method 1) 2) Using PET with chitosan acid solution pre-treatment (Method 2) 3) Using PET with chitosan pre-treatment and subsequent crosslinking using citric

Until now, the question of forgiveness has been studied mainly from the perspective of pastoral care. This means that forgiveness has been treated as a psychological means which cures both the victims and the offenders and builds reconciliation between them. However, this article deals with the question of forgiveness from the philosophical and theological perspective.

Both historians and political scientists have been using the study of diplomatic history in their majors until now. However, because of an obscurity of the study's sphere between these scholastic field, the study lost characteristic research results and its standatd of mutual benefit. Under these circumstances, two studies conflict by emphasizing their differences and don't make qualitative development of the study of diplomatic history. In 1978, some institutes like the Smithsonian Institutes
