Free-grazing ducks play a major role in the rural economy of Eastern Asia in the form of egg and meat production. In Thailand, the geographical location, tropical climate conditions and wetland areas of the country are suitable for their husbandry. These environmental factors also favor growth, multiplication, development, survival, and spread of duck parasites. In this study, a total of 90 free-grazing ducks from northern, central, and northeastern regions of Thailand were examined for intestinal helminth parasites, with special emphasis on zoonotic echinostomes. Of these, 51 (56.7%) were infected by one or more species of zoonotic echinostomes, Echinostoma revolutum, Echinoparyphium recurvatum, and Hypoderaeum conoideum. Echinostomes found were identified using morphological criteria when possible. ITS2 sequences were used to identify juvenile and incomplete worms. The prevalence of infection was relatively high in each region, namely, north, central, and northeast region was 63.2%, 54.5%, and 55.3%, respectively. The intensity of infection ranged up to 49 worms/infected duck. Free-grazing ducks clearly play an important role in the life cycle maintenance, spread, and transmission of these medically important echinostomes in Thailand.

본 연구의 목적은 자유선택활동 시 놀이 인원수 제한규칙에 따른 유아의 놀이를 알아보는 것이며, 본 연구결과가 자유선택활동 운영 개선에 기여할 것으로 기대된다. 연구참여자는 사립유치원 4세 학급 유아 25명과 담임교사와 공동연구자인 도움교수였다. 2014년 7월부터 10월까지 유아 관찰, 유아 인터뷰, 교사의 반성적 저널쓰기를 통해 자료를 수집하였다. 연구 결과, 유아들은 영역 선택을 표시하기 위해 사용하는 이름표에 대한 스트레스를 받고 서로 간의 과도한 경쟁을 하고 있었으며 규칙을 위반하고 있었다. 이를 통해 연구자들은 인원수 제한규칙이 유아의 도덕성 발달 제한, 사회정서발달 저해와 안전사고 위험, 자유선택 행동 저해 등의 역기능이 있음을 발견하였다. 이러한 규칙의 역기능을 인식한 연구자는 인원수 제한규칙을 해제함으로써 유아의 변화를 살펴보았고, 그 결과 공간 놀이 갈등 조절에서 유아의 자율성이 증진되었으며, 자유선택활동 시 교사의 역할과 운영방법에도 변화를 가져왔다. 연구결과에 기초하여 자유선택활동의 다양한 제한규칙의 필요성과 바람직한 규칙 적용에 대해 논의하였다.

The purpose of this study was to examine different child care curricula according to teacher's teaching method types. The subjects of the study were three hundred and fifty-six teachers, who were divided into four groups according to their teaching method: mixed method(type A), child oriented method(type B), teacher oriented method(type C), and beliefless method(type D). The data on the duration of free play and outdoor play time, activities frequently practiced in class, and outside one the playground were collected. The dimensions of child care programs were measured using Moore(1994)'s "The Early Childhood Dimensions of Education Rating Scale". The results of this study were as follows: first, teachers who used child oriented teaching methods gave more free play time than teachers using teacher oriented or mixed teaching methods. Second, teachers using teacher oriented methods showed the closeness and teachers using child oriented methods showed the openness in child care programs. Last, the activities teachers thought were the most important differed according to the teachers' methods even though in actual practice, there was no difference shown.

This study on filial play therapy training as parent education included 12 experimental group mothers, 11 control group mothers, and their 5-year-old children. Over 5 weeks, experimental group mothers received 2 hours filial therapy training 10 times, twice a week, and 30 minutes home special play 4 times, once a week. Each mother was videotaped playing with her child and completed three self-report instruments : Parental Acceptance Scale(Porter, 1954), Parenting Stress Index(Abidin, 1990), and Child Behavior Checklist(Oh et al., 1997) before and after the training. Pre- and post-test data was analyzed by paired-t test. Filial play therapy training enhanced empathy in adult-child interaction during free play. Significant increases appeared in parental acceptance level of child's feeling and autonomy.

희랍신화는 마법의 눈으로 바라본 자연과 세계를 상징적으로 재현하여 구조화하고 해석하는 상상놀이이다. 호메로스(Homeros)와 헤시오도스(Hesiodos)의 희랍신화는 신들의 이야기이지만 인간의 상상력이 상징 요소들을 통해서 자연현상의 근원과 원인을 이해 가능하도록 가공한 상상의 세계이며, 인간의 운명을 이해하는 틀이다. 상상세계로서 신화는 완전한 허구가 아니라 마법의 눈으로 바라본 인간의 현실이 상징적으로 재현된 세계이다. 신화는 한편으로는 이미 있는 인간세계를 모사하는 재현의 놀이이기도 하고 또 한편 지금까지 없었던 새로운 현실을 투사하는(project) 상상력의 놀이이기도 하다. 인간이 재현과 상상력을 통해 자유롭게 유희하는 세계가 바로 신화세계이다. 상상의 놀이로서 나타나는 신화와는 달리, 자연철학은 메타포를 통해서 세계의 구조와 운행법칙을 해명하고자 한다. 엠페도클레스, 데모크리토스 등의 자연철학자들은 자연 변화를 다양한 아르케들의 작용들로 파악하고 그 변화 과정을 아르케의 이합집산으로 설명하고 있다. 헤라클레이토스에 이르면, 세계생성을 놀이적 성격을 통해서 해명하려는 철학적 사유가 생겨난다. 그는 놀이로 존재의 의미를 규정하려는 전회를 시도한다. 헤라클레이토스의 "단편 B52"는 생성소멸의 세계를 영겁의 세월을 노는 아이로 비유한다. 세계는 일종의 신적인 놀이이며, 놀이는 존재자의 의미를 해명하는 단초이다. 놀이에는 세계 전체가 투영되어 있다. 그는 "어린아이의 놀이"를 통해서 세계가 목적 없이 창조되었고 끝없이 변화된다는 것을 표현한다. 철학적 사변은 놀이라는 메타포로서 세계를 파악한다.

The purpose of this study was to examine children's dramatic play and dramatic play themes in the same-age and mixed-age kindergarten classrooms. The subjects were 45 children in three classrooms of 4-year-olds, 69 children in three classrooms of 5-year-olds, and 60 children in three mixed-age classrooms of 4-and 5-year-olds. Observations were conducted by videotape recordings. Observation periods were of five-minutes duration. There were ten observations of children's indoor free-play periods. Four-and five-year-olds in mixed-age classrooms were more likely to engage in group-dramatic play than 4-and 5-year-olds in same-age classrooms. Four-year-olds in mixed-age classrooms were more likely to engage in domestic and family, war/violence, school, animal, and vehicle play themes than 4-year-olds in same-age classrooms. However, 5-year-olds in mixed-age classrooms were more likely to engage in family and school play themes than 5-year-olds in same-age classrooms. 5-year-olds in same-age classrooms were more likely to engage in vehicle and animal play themes than 5-year-olds in mixed-age classrooms. 5-year-olds in same-age classrooms did not differ from 5-year-olds in mixed-age classrooms on the war/violence themes used during dramatic play. In terms of sex differences, boys were more likely to engage in violence, adventure fantage themes than girls. Conversely girls were more likely to engage in family/marriage static play themes than boys.

Purpose: This study was done to analyze children's play during hospitalization. Method: Data were collected from 36 play situations of hospitalized children, ages 2 to 6, hospitalized at 4 general hospitals, one in each city, Seoul, Suwon, Daejeon and Daegu. All observations were made in pediatric units during free-play periods. Each child was observed for 5 minutes at each observation and observed three times at each play session. Results: Of the children, 83.3% played on the bed. Play partners were mainly mothers. While 75.0% of children actively took part in play activity and 70.0% played with joy, 63.9% of play partners were more passive in the play. The most frequent play material was a small toy. The level of play was early stage of social and cognitive play, and dramatic play was observed in a few children over the age of 3 years. The play activities were conversional play, reflections of therapeutic procedures, imagination, and exploratory play. In the conversional play, children converted hospital equipments into play materials. Conclusion: It is recommended that health care team members should pay attention and actively participate in play of hospitalized children in order to help them have some control over the stress of the situation.

The purpose of this study was to investigate the effects of children's multiple intelligences and temperaments on their play behaviors. In order to achieve this, 155 mothers and 21 teachers of children aged 4 to 6 years old were invited to participate in an observe-reported survey. The data were analyzed using descriptive statistics, Cronbach's ${\alpha}$, Pearson's correlation, and hierarchical regression analysis using SPSS version 18.0. It was found that both multiple intelligences and temperament types have partial influences on play behaviors of young children; it was confirmed that among multiple intelligences of children, logical-mathematical intelligence influences onlooker behaviors in a positive way, body-kinesthetic intelligence has a positive effect on rough-and-tumble play, and musical intelligence positively affects social play during free-choice play. Also, children with a difficult temperament were more likely to participate in solitary play than children with a slow temperament. These results imply that teachers' guidance and involvement of children's play should differ by types of temperament and levels of multiple intelligence in children.

The purpose of this study was to describe and understand the characteristics of morphological, contextual as relational aggression among 4-year old children during free play periods. The ethnographic methods included participants observation of children's play interaction behaviors, field notes, video taping and analysis of transcribed date. The results are as exclusion occurred by group power taking the relational attribute, including direct language, while the other would not be revealed easily other than being in line with real relation. Also as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatrning their friend' and 'withdrawal of friendship'.
