Objective: The purpose of this study is to examine whether the 'Ordinance for Guaranteeing Children's Right to Play' is has been implemented well and investigate play practice in elementary school. Methods: For this study, a survey was conducted on 319 elementary school teachers in Jeollanam-do. Results: First, elementary school teachers' perception of the enactment of the 'Ordinance on Children's Right to Play' is high. And their perception is positive about the effect of the 'Ordinance on Children's Right to Play'. Second, among the roles of the Office of Education, play-related training and club support were relatively low. The role of the elementary school director was relatively low in the analysis and disclosure of play performance. Third, the time that children mainly play in school is the middle play time. The sufficiency and safety of play spaces differed by region. Fourth, the contents to be added to the 'Ordinance' are securing play space, budget support, and mandatory play time. Conclusion/Implications: In the future, 'Ordinance on Children's Right to Play' should go through a process of improvement so that children's play is realized as a right.

Objective: The purpose of this study is to gain basic information for parental education by investigating parent's implementation and perception of children's right to play. Methods: The subjects of this study were 458 parents who have a child in kindergarten or 1st grade of elementary school in J city. The research tool used in this study, the Parent's Perception of and Implementation for Children's Right to Play(PPICRP), was developed by researchers. PPICRP is a 5type rating scale questionnaire which includes the selection of a space for play, play time, play mate, instrument, etc. The data were analyzed by using the SPSS 18.0 program. Results: The results showed that the parent's implementation for children's right to play was lower than the parent's perception of it except for the selection of play instrument. Conclusion/Implications: The results of this study imply that there is a need for parent education which contains concepts and stresses the importance of play, which implement children's right to play. The unexpected result in the play instrument, the excessive organization of the play by adults, and the difference of parent's implementation according to the gender of their children were further discussed.

유엔아동권리협약은 아동이 충분한 휴식과 여가, 놀이에 참여할 수 있도록 적절하고 균등한 기회를 제공하기 위해 노력해야 함을 규정하고 있다. 이에 따라, 최근 아동의 권리 측면에서 놀이의 중요성이 지속적으로 강조되고 있으며, 놀이를 위한 시설과 공간의 필요성이 재차 언급되고 있다. 한편, 국내에서는 놀이시설의 수가 지속적으로 증가하고 있는 추세임에도 불구하고 아동의 놀이 공간에 대한 개선 노력이 요구되고 있다. 따라서 본 연구에서는 놀이권 보장 측면에서 놀이 및 놀이공간에 대한 현행 제도와 정책에 대해 재검토하며, 국외 관련 제도와의 비교분석을 통해 제도적 시사점을 도출하고자 하였다. 국내 어린이놀이터의 법적 개념과 관련 법령, 조성 기준, 자치 조례를 분석하였으며, 영국, 캐나다, 독일의 관련 제도를 주요 특성 중심으로 분석하였다. 비교분석의 결과를 바탕으로 놀이권 보장 측면에서 어린이놀이터 제도 개선 방향을 네 가지로 제안하였다. 첫째, 어린이놀이터의 개념과 범위에 대한 법적 정의를 마련하여야 한다. 둘째, 안전관리 중심의 시설 규정을 넘어 놀이권 보장을 위한 제도적 보완이 필요하다. 셋째, 단위 시설이 아닌 공간적 개념으로서 어린이놀이터에 대한 포괄적 접근이 필요하다. 넷째, 어린이놀이터 조성과 관련된 구체적인 지침 및 가이드라인을 통해 질적 관리가 필요하다. 이러한 결과는 향후 도시계획, 아동복지, 교육 분야 등에서 놀이권 보장을 위한 제도개선을 추진함에 있어서 근거자료로써 활용될 수 있을 것이다.

The aim of this study is to examine children's desires in a toy library and what they want to do there in order to reflect their opinions on constructing a toy library in a child care center. The study has been conducted by participatory observation on a 'toy library' project consisting of 20 five-year-olds attending B public child care center in Seoul. Observational notes were taken with voice and video recordings. The results of analysis on collected data are as follows. First, the children wanted to call the toy library a toy playground because a toy library is not for study but for play and they wanted space for rest and display with no surveillance camera. Second, they wanted to play freely without any interruption, even leaving things scattered and also wanted to play with parents and friends. Discussion followed in the view of children's right to play and to express their opinions.

This paper investigates whether white-collar masculinity can play a role in the life of a far-right activist. The current study employs the methods of psychosocial analysis devised by Wendy Hollway and Tony Jefferson. Using the case of a Japanese far-right activist, it explores how the hegemony and decline of "salaryman masculinity" in Japan interacted with his life. It draws attention to the suffering of white-collar men in their struggle to comply with hegemonic masculinity. These men's suffering tends to be overlooked due to their stable socio-economic status, but it can potentially play a role in their investment in far-right discourse.

This article continues the study of right 𝜋-duo rings, concentrating on the situation of nonzero powers. For this purpose we introduce the concept of strongly right 𝜋-duo and examine the structure of strongly right 𝜋-duo in relation to various ring properties that play important roles in ring theory. It is proved for a strongly right 𝜋-duo ring R that if the upper (lower) nilradical of R is zero then R is reduced. Various kinds of examples are examined in relation to the questions raised in the procedure.

Quality and economy in radiography can be achieved by using the right techniques and the film material available on the market. Pre-packing with or without lead, under vacuum or not, play an important role provided the right kinds of procedures are applied. The author explains some of the ways used by different N.D.T.companies to achieve the best quality in an economical way.

The concepts of reversible, right duo, and Armendariz rings are known to play important roles in ring theory and they are independent of one another. In this note we focus on a concept that can unify them, calling it a right Armendarizlike ring in the process. We first find a simple way to construct a right Armendarizlike ring but not Armendariz (reversible, or right duo). We show the difference between right Armendarizlike rings and strongly right McCoy rings by examining the structure of right annihilators. For a regular ring R, it is proved that R is right Armendarizlike if and only if R is strongly right McCoy if and only if R is Abelian (entailing that right Armendarizlike, Armendariz, reversible, right duo, and IFP properties are equivalent for regular rings). It is shown that a ring R is right Armendarizlike, if and only if so is the polynomial ring over R, if and only if so is the classical right quotient ring (if any). In the process necessary (counter)examples are found or constructed.

본 연구는 유치원의 자유놀이 제한 규칙에 대한 교사의 인식을 알아봄으로써 유치원 자유놀이 운영을 위한 기초적인 정보를 얻을 목적으로 수행되었다. 이를 위하여 J 지역에 근무하는 유치원 교사 200명을 대상으로 설문 조사를 시행하였다. 연구 도구는 학급 내 자유놀이에 대한 제한 규칙에 관한 교사의 인식을 묻는 설문지였다. 연구 결과는 다음과 같다. 첫째, 교사는 흥미영역 중 미술영역에 대한 제한 규칙의 필요성을 가장 높게 인식하였다. 둘째, 교사는 세 가지 유형의 제한 규칙 중 인원수 제한 규칙의 필요성을 가장 높게 인식하였다. 셋째, 제한 규칙의 필요 이유에 대한 교사 인식은 다음과 같았다. 인원수 제한 규칙 필요 이유는 일부 영역으로 쏠리는 현상을 예방하기 위해서였다. 시간 제한 규칙 필요 이유는 다양한 흥미영역에서 놀이하도록 지도하는 것이 교육적이라고 생각하기 때문이었다. 공간 제한 규칙 필요 이유는 각 흥미영역 고유의 교육목표를 확실히 할 수 있기 때문이었다. 유아의 놀이 권리와 연계하여 자유놀이 제한 규칙의 의미와 필요성을 논의하였다.

Background and Objectives: Mitochondria play a key role in the pathophysiology of heart failure and mitochondrial permeability transition pore (MPTP) play a critical role in cell death and a critical target for cardioprotection. The aim of this study was to evaluate the protective effects of cyclosporine A (CsA), one of MPTP blockers, and morphological changes of mitochondria and MPTP related proteins in monocrotaline (MCT) induced pulmonary arterial hypertension (PAH). Methods: Eight weeks old Sprague-Dawley rats were randomized to control, MCT (60 mg/kg) and MCT plus CsA (10 mg/kg/day) treatment groups. Four weeks later, right ventricular hypertrophy (RVH) and morphological changes of right ventricle (RV) were done. Western blot and reverse transcription polymerase chain reaction (RT-PCR) for MPTP related protein were performed. Results: In electron microscopy, CsA treatment prevented MCT-induced mitochondrial disruption of RV. RVH was significantly increased in MCT group compared to that of the controls but RVH was more increased with CsA treatment. Thickened medial wall thickness of pulmonary arteriole in PAH was not changed after CsA treatment. In western blot, caspase-3 was significantly increased in MCT group, and was attenuated in CsA treatment. There were no significant differences in voltage-dependent anion channel, adenine nucleotide translocator 1 and cyclophilin D expression in western blot and RT-PCR between the 3 groups. Conclusions: CsA reduces MCT induced RV mitochondrial damage. Although, MPTP blocking does not reverse pulmonary pathology, it may reduce RV dysfunction in PAH. The results suggest that it could serve as an adjunctive therapy to PAH treatment.
