이동객체 색인에 관한 기존 연구는 실외 환경의 빠른 속도로 이동하는 많은 이동객체들을 대상으로 과거 궤적과 현재 위치 및 미래 위치를 검색하는 색인 기법들이었다. 그러나 쇼핑몰이나 대형 박물관과 같은 건물의 실내나 놀이동산과 같은 한정된 영역의 이동객체들은 실외 환경에서처럼 빠른 이동속도를 가지고 있지 않다. 또한 이동객체들의 이동하는 영역이 한정되어 있을 뿐만 아니라 최대 수용인원 등이 정해져 있다. 본 논문에서는 이러한 특성을 갖는 실내 환경에 적합한 색인 기법으로 현재 그리고 미래 위치 질의 처리를 위한 공간색인과 시간 색인을 분리한 두 개의 색인 구조를 갖는 새로운 색인 기법과 가까운 미래 시간의 특정 영역에 있는 이동객체들의 수에 대한 질의응답을 위한 시공간 히스토그램을 구성하고, 적용하는 방법을 제안한다.

본 연구는 아동의 탐색활동에 관한 연구에 지침이 되고 자극을 주고자, 또한 실제 지도에 있어 시사점을 발견하고자 이 분야에 관한 주요연구문헌을 고찰하였다. 그리하여 탐색활동을 놀이와 호기심과 비교하여 그 정의를 내리고 탐색활동의 기능과 특징, 그리고 이 활동에 영향을 주는 제 요인을 살펴보았다. 그 결과 아동의 탐색활동에 관한 연구자간의 의견차이를 보이는 것이나 연구공백이 있는 것이 여러부분이 됨이 드러났다. 즉 놀이와 탐색활동과의 구별, 탐색활동과 호기심과의 관계, 탐색활동의 동기, 상황에 따른 탐색활동의 유형변화, 탐색활동을 유발시키는 자극물의 특성-특히 공간적 특성, 탐색활동과 아동의 년령, 성별, 인지적 발달단계와의 관계, 그리고 탐색활동에 있어서의 개인차 등에 관해 더 많은 연구가 요구됨을 알 수 있었다. 특히, 아동의 탐색활동과 지적발달 또는 사회성 발달과의 관계나 아동의 발달과정에 따른 훈련이나 교육을 동한 탐색활동의 증진방안 등은 시사성 있는 중요한 연구테마로 보여진다. 또한 이 탐색활동에 관한 연구에서도 실험실에서 이루어진 연구가 자연적인 상황에 얼마나 일반화 될 수 있는지, 한 번의 관찰이나 실험이 계속적인 의미를 지닐 수 있는지에 대해 연구자들이 더욱 신중해야 할 필요성이 있음이 드러났다. 물론, 한 가지 이론이나 연구로서 탐색활동의 전부를 설명할 수는 없다. 유아교육자들이나 아동학자들은 아동이 그 자신의 환경에 적응하고, 사회적 유능성을 함양시키고, 진정한 의미에서의 지능발달에 중요한 것으로 드러난 이 아동의 탐색활동에 관해 더욱 관심을 가지고 여러 가지 이론과 연구를 빌어 연구나 실제 지도에 필요한 아이디어를 삼아야 할 것이다.

This study examines the changes of the online music market and revenue models by the theory of network society and communications of Manuel Castells for the content platform. As a result of this study, we found that active communications among the members in the network, played a crucial role in the creation of contents and the promotions of profit for platform providers. It is especially important to create an environment in which members can voluntarily communicate rather than an artificial control. The content platform business consists of people, thus it has been proven that providing play elements of culture and society are important, as well as necessary conditions to the generation related to content based platform businesses.

This study examined the relationships between teacher variables that improve the efficacy of the play teaching of infants and toddlers following a play-oriented curriculum. The participants were 287 infant teachers. The results were as follows. First, the independent variables had a significant effect on the efficacy of play teaching, teacher-infant interaction, and classroom environment. Second, the mediating effects of teacher-infant interaction and classroom environment on the effect of independent variables on the efficacy of play teaching were as follows. The interaction mediating effect between professionalism and play belief was significant, but teaching creativity was found to be significant. In the mediating effect of the classroom environment, expertise, play belief, and teaching creativity were found to be significant. Third, both teacher-infant interaction and the multimedia effect of the classroom environment were statistically significant in mediating the effect of independent variables on the efficacy of play teaching. These results provide basic data on the necessity for teacher education to explore ways to improve teachers' sense of efficacy in teaching play and their teaching skills.

Objective: The present study aimed to investigate the sequential mediation effects of creative home environment and preschoolers' playfulness on the relationship between mothers' play beliefs and preschoolers' happiness. Methods: The subjects of this study were 233 preschoolers between the ages of 3 and 5 and their mothers. Mothers were asked to complete a questionnaire that assessed their beliefs about play, the creative home environment they provided, as well as their child's playfulness and happiness. The data collected were analyzed using the SPSS Process Macro program to investigate the sequential mediating effects. Results: The study found that the mothers' play support beliefs were directly associated with their preschoolers' happiness. Additionally, the creative home environment was found to mediate the relationship between the mother's play beliefs and their preschooler's happiness. The children's playfulness was also identified as a mediator in the relationship between the mother's play beliefs and their preschooler's happiness. Furthermore, the findings of this study indicated that the relationship between the mother's play beliefs and preschoolers' happiness was sequentially mediated by the creative home environment and preschoolers' playfulness. Conclusion/Implications: Findings of this study provide insights into the potential development of a parent education program aimed at modifying mothers' play beliefs and the home environment.

This study will examine the current condition of outdoor play in child care centers and the overall perception of teachers on outdoor play in regards to its related programs and children's reaction to them. Through examining such issues, this study will provide the basic data that can be applied in planning appropriate outdoor play activities, programs and environments. For the study, we surveyed teachers and directors of child care centers using a structured questionnaire. The objects of the survey were 22 child care centers in Daejeon and Seoul, who agreed to conduct the survey. The survey was conducted from August 1 to September 30 2006; 220 copies were distributed, and 188 copies were collected. The results of the study can be summarized as follows: 1) The number of outdoor plays per week were on average 1~2 in most cases, although teachers believed the play should be done everyday. Outdoor play time was mostly 21~30 minutes, while teachers thought 31~40 minutes as appropriate. Children's reaction scored the highest when they played outdoors for 30 minutes every day with their teachers involved in the play. As a result, we have concluded that the appropriate outdoor play should be conducted everyday for 30~40 minutes. 2) Outdoor play was mostly conducted as part of the overall educational plan rather than a separate plan. Since outdoor play affects children's development as much as indoor play, there is a need for development of a specific and separate plan for various outdoor play programs. 3) The outdoor play program that was most often conducted was equipment play and sand play. This indicated the monolithic nature of the outdoor program. Given the fact that children enjoy outdoor plays a lot (M=4.71), various programs including adventure play, sensitive play, and carpenter play should be developed. 4) In outdoor play, the teacher's role included supervising and interacting with children. According to the survey, teachers had a good understanding of the importance on safety and supervising issues in outdoor plays. However they seemed to overlook the importance of having better programs and improving teacher's participation to the play. Despite the importance of outdoor play to children's development, the result shows that teachers have tendencies to limit and obstruct outdoor plays by emphasizing supervising and safety issues instead. 5) Children's safety should not be the only consideration for outdoor plays; teachers ought to better understand that children's development can be maximized by the play. Furthermore, there should be emphasis placed on the program development and teacher's participation; teacher's participation should actively encourage the interactions between a child and a teacher, as well as among children.

'Play' itself is enough of a motivation for anyone to do it. Still, it will be very difficult to continue to enjoy meaningless and aimless repetition of fights, mimicking, chases, discoveries or changing of sceneries by the mechanism alone. Of course, in rare occasions there are games like Tetris which can be enjoyed on its great gameplay alone for hours. But for most cases, players need goals, initiatives, and dynamism through storytelling for their experiences to be a rich one. Validity and feasibility of storytelling in games has always existed with plenty of skepticism. However, as games evolved from some small play mechanisms for spare times to a major entertainment with recognizable volume and content, a need to keep players interested and participating has made storytelling an essential ingredient. Storytelling within games has to have different meanings and shapes to existing narratives. Hence, new definition and methodology must emerge and studies has been active. If a case can be made so that a tested and tried methodology that has been successful for other media can be substituted for games, then it can bring a new direction to the ongoing studies. This study will borrow some methodology from cinema which can sometimes be seen as opposite to games and sometimes as something games want to be alike.
