The purpose of this study was to examine the relation between forms of children's solitary play and temperament, problem behaviors. Seventy-six children of four-year-olds were observed during free play. Children's temperament was measured by mothers of participants. Children's problem behaviors were measured by teachers. Following from Coplan et al(1994), this study were analyzed three aggregate measures of solitary play consisting of reticent behavior, solitary-passive play, and solitary-active play. The results of this study shows that first, the highest frequency of solitary play's forms was reticent behavior, followed by solitary-passive play, then solitary-active play. There weren't any differences in children's solitary play according to their gender. Second, there were significant differences among forms of children's solitary play and temperament. And there were gender differences in the correlates of different forms of solitary play. Third there were significant differences among forms of children's solitary play and problem behaviors. Also, there were gender differences in the correlates of different forms of solitary play. This result points out the important of solitary play and distintion of solitary play'forms.

The purpose of this study was to investigate the relationships between play behaviors and young children's playfulness in a variety of play space environments. The subjects were 150 4-year old children of 29 mixed-age classes in childcare centers of Seoul and Gyeonggi area. The results were as follows; (1) Their play behaviors differed according to their play environment in terms of classroom spaces. Solitary-active play behaviors were more frequently observed in large play spaces than small. (2) Leading participation, cognitive flexibility, voluntary full immersion, and total playfulness scores correlated negatively with reticent behavior. Leading participation, voluntary full immersion, and total playfulness scores, on the other hand, correlated positively with group play behavior. (3) In small play spaces, leading participation, voluntary full immersion correlated negatively with reticent behavior, but leading participation correlated positively with group play. In middle play spaces, cognitive flexibility correlated negatively with reticent behavior. In large play spaces, voluntary full immersion correlated negatively with parallel play, but leading participation, cognitive flexibility, expressions of joy, voluntary full immersion, and total playfulness score correlated positively with group play.

PURPOSE This study was intended to analyze the play-form of normal preschool children as related to age, sex, educational experience and social maturity. METHOD 1. Subjects The subjects of this study were eighty seven 3-, 4- and 5-year-old preschool children attending educational institutions in Seoul. 2. Instruments The instruments used in this study consisted of twenty one-minute observations in 5 preschool settings and a questionnaire designed to measure the children's social maturity filled in by their parents. The observations provided information on the children's free play, that is 1) play-form: solitary, parallel and group play 2) use/non-use of toys 3) behavior: play, activity, doing nothing, onlooking 4) stationary/moving dimensions 5) play group size The questionnaire measured such factors as communication, socialization, locomotion, self-help and self-direction. 3. Data Analysis Data analysis consisted of percentage and Chi square. RESULTS 1. Play-Form The relationship between age and play-form proved to be significant at the .05 level. That is, in both boys and girls, solitary play decreased with age and group play increased with age while parallel play maintained a similar position. The relationship between sex and play-form proved to be significant at the .05 level in 3-& 4-year-old children, but not significant in 5-year-old children. That is, in their $3^{rd}$ year boys engage in the solitary play more than girls and in their $4^{th}$ year boys engage in more group play than girls. 2. Toys Without differentiation of sex and age, cases of using toys in play exceed those cases where toys were not used. 3. Behavior The relationship between age and behavior proved to be significant at the .05 level in both boys and girls. That is, with increase of age, play decreased and activity increased in boys while play increased and doing nothing decreased in girls. 4. Moving Status Totally, moving occurred more frequently in play than stationary status. Moving proved not to have a significant relationship with age, but it did Navel a significant relationship with sex at the .05 level. That is, moving tended to increase with the increase in age in both boys and girls, but not at a significant level. Boys moved significantly more than girls in all three age levels. 5. The Relationship between Educational Experience and Play-Form There was a tendency for children with longer preschool experience to engage in less solitary play and more group play than children who had less than one semester of preschool experience, but this difference was not statistically significant. 6. The Relationship between Social Maturity and Play-Form The high social maturity group engaged in less solitary play and more group play than the low social maturity group, but this was not a statistically significant difference. 7. Play Group Size Play group size was 2~10 children, but the majority of play groups consisted of 2~3 children. There was a tendency for play groups composed of 2 children to decrease with age and play groups composed of 3 children to increase with age. No significant difference was found between the sexes in play group size.

The purpose of this study was to investigate the differences in children's play behaviors in terms of their levels of playfulness, leadership and communicative ability. The subjects were 152 children aged between 3 and 4, and their 20 teachers at 10 child care centers in the Seoul and Gyeonggi area. The results of this study suggested that play behaviors were related to the level of playfulness, leadership and communicative ability in 3 and 4 years old children. Among these children, those who scored highly in terms of their playfulness, leadership and communicative ability were involved more frequently in both 'group play' and 'symbolic play' whereas those who achieved lower scores were more frequently involved in 'solitary play' and 'functional play'. However, in case of 'constructive play', significant results were not found in relation to the independent variables named in this study. 'Parallel play' and 'games with rules' were the only categories within which the findings revealed that children's play behaviors have shown different patterns according to the age of the child and to the levels of those three independent variables mentioned above.

This study examined whether sequential transition patterns of social play differed by children's social competence. The social competence of sixty 5-year-old children was rated by their teachers using the Social Competence Scale(NICHD Early Child Research Network, 1996). Children's social play was observed during free play and coded by criteria developed by Robinson et al(2003). Results showed differences in children's social play behaviors by social competence and differences in the transition patterns of children's social play level by social competence. Children with higher social competence showed a transition pattern moving toward cooperative-social interaction, whereas children with lower social competence showed a transition pattern moving backward to solitary or onlooker behavior.

The purpose of this study was to investigate the current status of family child care. The status of family child care was explored in terms of general characteristics, program quality, and child behavior. The subjects were 17 family child care and their 102 children and 60 parents. Harms & Clifford's (1989) FDCRS(Family Day Care Rating Scale) was used to measure program quality. Child behavior was recorded by time sampling in two 30 min observations during the free play session in each facility. A questionnaire for caregiver and parents was used to investigate general characteristics. The data were analysed by frequency, percentage, and Pearson's r. Results showed that (1) a wide range of variable accounted for the general characteristics of family child care, (2) the level of program quality as rated by the FDCRS was below mid-point, (3) children engaged in solitary behavior much more than in peer interactions or caregiver-child interactions.

The experience and play activities in forest spaces have played an effective role in children's growth and development, therefore, many studies and projects related to forest activity space have progressed actively. However, the focus of previous research has been merely on the effectiveness of forest activity but little on providing the basis for the spatial design of these types of forest activity spaces. Thus, this study aims to identify the relationship between children's developmental play activity and the physical characteristics of forest activity spaces for evidence-based design. First of all, indicators for Cognitive-Social play(CSP) was selected and forest spaces were categorize into play facility spaces and forest spaces. More detailed environmental characteristics of each space were 'play area' and 'paving materials' for play facilities and 'density of tree and shrub', 'slope', 'paving materials' and 'fixing and type of natural loose parts' for forest space. Through environmental inventory and behavior observation, the types of play behaviors and the occurrence frequency of children aged four to five were collected and analyzed. The results were as follows: 1) In play facility spaces, play behaviors occurred at a high frequency at the facility playground with play facilities and sand area. In terms of CSP, functional-solitary and functional-parallel plays occurred predominantly. 2) In forest spaces, various play behaviors occurred at high frequency in the environment with low density planting and various natural loose parts. For CSP, functional-group and symbolic-group plays occurred at a high frequency. 3) Symbolic-group play appeared to be highly affected by environmental characteristics like tree area of scatter density or less, 10~20 degree slope, and the presence of fixed large stumps. In conclusion, this study provides standards of physical environmental characteristics for forest activity space design through direct observation and analysis of children's play behaviors.

A solitary endoparasitoid, Cotesia plutellae, parasitizes diamondback moth, Plutellae xylostella. It has been suggested that its antennae are a major sensory organ to search host and recognize host developmental and other physiological condition during parasitization. This research was performed to understand the parasitic behavior of C. plutellae by analyzing sensory types and their numbers on the antennae using scanning electron microscope. There was no significant difference in antennal length in both male and female C. plutellae, in which both sexes had 16 flagellomeres. Three different types of sensilla (trichoid, seta, and placodea sensilla) were located mostly on flagella and analyzed in their density on the different antennomeres. Trichoid sensillum was the major sensory type and showed about 87% density among all sensilla. Both trichoid and placodea types of sensilla exhibited even numbers on all flagellomeres with some decrease at terminal segments. In contrast, seta form of sensilla showed drastic increase in its density at distal part after 9th flagellomere. When distal half of flagellomeres were cut off, the C. plutellae could not parasitize host larvae. Even when only four distal flagellomeres were removed, the parasitism showed only 30%. These results indicate that C. plutellae antennae are required for parasitism and suggest that seta form of sensilla may play significant roles in recognizing host for parasitization.
