This study investigated the proceeding patterns of constructive play with lego blocks, and the differences on the quality of constructive play and symbolic play's pretending elements. The subjects were 132 children at child care centers and kindergarten: 64 three-year-olds (36 boy, 28 girl) and 68 five-year-olds (32 boy, 36 girl). The study found three proceeding patterns in the constructive lego play. First, children engaged in constructive and symbolic play simultaneously, or they switched back and forth between symbolic and constructive play. This pattern was termed as "constructive and symbolic play simultaneously or alternatively"(type 3), and it was occurred most frequently. Secondly, children focused only on constructing structures. This pattern was termed as "constructive play only"(type 1), Thirdly, children engaged in symbolic play only after they completed building some structures. This pattern was named "symbolic play after constructive play"(type 2). The findings also indicated that children who were categorized as type 1 and 2 showed higher quality of constructive play and longer duration in play than children as type 3. Five-year-old children sustained play longer and showed higher quality in terms of elaboration, imagination, and variety (number of blocks, shape of blocks). Furthermore, children as type 3 showed a higher level of imaginative play than children as type 1 and 2, especially in terms of role, objet, and context of projection.

This study examined the relation between the quality of constructive play and convergent and divergent problem solving. The subjects were 48 five-year-old children. Unit blocks were used to test the quality level of constructive play; a 40 piece puzzle and pattern blocks were used to test convergent problem solving; the pattern blocks also were used to test divergent problem solving. Children's block play was videotaped and pictures were taken of constructions made by children. Data were analyzed by correlation and stepwise multiple regression. Results showed statistically significant correlations between the quality of constructive play and convergent and divergent problem solving. Among the sub variables of constructive play, social play patterns affected convergent problem solving; diversity affected divergent problem solving.

The purpose of this study was to analyze the quality of the constructive play of 3, 4 and 5 year-old children. The researchers used unit blocks as the instrument because they are the most representative examples of constructive play materials. The subjects were 73 children enrolled in a half-day early childhood education program. The children's block play was videotaped 8 times, for a total of 330 minutes. The videotapes were transcribed and assessments were made on the children's 233 constructions in terms of the developmental stage of block play, the variety of materials used, play duration, and play intensity. The data were analyzed through two-way ANOVA to check age and sex differences. The results showed that children's developmental stages of block play were low on the average and that girls did not show an active interest in block play. The results also implied that block play developed by play experience rather than by age. Therefore, this study was interpreted to highlight the importance of teachers' understanding, planning, and mediation of block play in order to induce high-quality constructive play.

Subjects were two teachers each with higher or with lower play teaching efficacy, and the 111 four and five-year-old children they taught. Using naturalistic observation, children's constructive play was videotaped and transcribed for 60 minutes on ten consecutive days in each classroom. Play was analyzed by level of constructive play, continuous length of play, variety of materials, enrichment of activities, and coherence of content. Constructive play of children whose teachers had higher efficacy in teaching play showed longer continuous play, used a higher variety of materials, and their play had more creative integrity. Five-year-olds exhibited longer continuous play, used a larger variety of play materials, more enrichment of play activity, and more coherence in play contents than four-year-olds.

Recently, user participatory workshops have been applied as a way to plan landscape spaces that reflects the needs and demands of the users. It is also required to improve the quality of the FECC (Forest Experience Center for Children), which is growing rapidly. Therefore, the purpose of this study is to deduct the design elements (forest play activities and space), the basic needs, and the demands of users in making the FECC a preschooler participatory workshop. For this, materials for preschooler participation were selected, and a step-by-step workshop was conducted to satisfy the demands of the preschooler's development. First, in the pre-workshops phase, design elements standards were deducted through the preschooler participatory results (41 children aged 6 and 7, Kindergarten). Second, in the main workshop phase, the design elements to be introduced on the site (Songsan-mulbit FECC) were deducted through the participating preschooler's selection and those results were analyzed. The materials used at the preschooler participatory process were 'drawing a picture' in the pre-workshop phase, and the design elements and the standard types charts were the forest play activity pictogram chart, and the forest play space general images chart in the main workshop. As for results, frst, there are 38 standard types of forest play activities that have been deducted. It consists of 27 cognitive activities (functional 16, constructive 4, symbolic 4, game on rule 3), 9 games (sensory 5, other 4), and two social play activities (solo, group). There are 21 standard types of forest play spaces. They consist of 8 play facility spaces (5 facility, 3 natural), 2 water spaces, and 11 spaces of 5 types. Second, as a result of applying the results to the site, the forest play activities to be introduced on the site were selected, and the functional play was most selected. Additionally, climbing and water play were most selected as the unit activities. Also, functional, constructive, symbolic, games based on rules were selected, even in the preschooler's development play. In the case of the forest play spaces to be introduced in the site, the preschooler's selection results by sex and age tended to be similar to the preschooler's comprehensive selection results, but the boys preferred function and adventure spaces more than the girls, while the girls preferred rest spaces more than the boys. This result is similar to the previous study results, which directly observed the preschooler's forest play behavior, and analysis that the preschooler recognized the site and selected the design elements introduced on the site. Therefore, the participatory workshop process and the materials process in this study are analyzed and applied to the purpose of the study. It is valuable as a case to be applied in design of the FECC from this point forward.

Recently, by developing many training systems in battle field, the demand for interconnecting and internetworking between Live, Virtual, Constructive training systems has been increased to support efficient data distribution and system control. But, there are lots of problems for them to interwork, because the existing researches only support L-L, V-V, C-C Interoperability. Therefore, we propose L-V-C gateway to provide interoperable simulation environment based on HLA and DDS between them. First, we illustrate FOM Management that parses RPR-FOM XML file to acquire Data information to be shared between them, and generates common data structure and source code used for L-V-C Gateway. L-V-C Gateway created from FOM Management supports Data Conversion and Quality of Service between HLA and DDS. HLA Federate and DDS Domainparticipant in L-V-C Gateway play a role of logical communication channel and relay data from HLA Federation to DDS Domain and vice versa.

Philosophical discussion and ethical approach have been crucial aspects in the rational decision-making of heritage conservation. This study analyses why and how they play an important role in determining the quality of conservation practice. It highlights the key concepts of conservation philosophy and ethics, as well as their relationship, in order to establish a constructive platform through which researchers may understand the role and importance of conservation philosophy and ethics. In conclusion, this study provides a set of recommendation for the government, academic experts, and conservators which will allow them to become actively involved in improving the quality of philosophical and ethical knowledge in the field of conservation.
