대부분의 온라인 게임에서는 아이템이나 사이버머니를 얻는 생산활동과 아이템을 구입하는 소비활동이 일어나는 등, 일종의 경제 시스템을 이루고 있다. 특히 최근에는 플레이어들이 아이템 현금 거래를 통해 현실과 게임간의 경제적 상호활동을 하고 있기 때문에, 게임 내에서 발생하는 경제 문제가 실제 게임업체의 매출과 수익성에도 영향을 줄 수 있다. 온라인 게임 내의 사이버머니 통화량 및 아이템 유통량에 대해 어떤 경제 정책을 세우는가에 따라 게임 서비스 회사의 수익성이 좌우된다. 때문에 게임 내부의 경제와 실물 경제의 상호 연관성을 파악하는 것이 게임 경영에 있어 중요한 이슈로 대두되고 있다. 본 연구에서는, 게임 속에서 구체적으로 어떠한 경제문제가 발생할 수 있으며, 그것이 유저의 게임동기와 회사의 수익성에 어떤 영향을 끼치게 되는지 파악하고자 하였다. 시스템 다이내믹스 방법론을 이용하여 온라인 게임의 일반 경제 모형을 개발하고, 이를 이용하여 몇 가지 시나리오에 대한 동태적인 시뮬레이션을 수행하였다. 이를 통해, 온라인 게임을 경영함에 있어 고려해야 할 주요 문제들에 대하여 논하였다.

현대 산업의 기업활동에 있어서 조직의 확대와 세분화,제품의 다양화 및 전문화에 따라, 생산활동을 위한 부서간의 정보 공유는 물론 협력업체, 부품공급 업체 상호간의 원활한 정보교환이 필수적인 요구 조건이 되고 있다. 그러나 이러한 기업환경의 변경에도 불구하고 이들 정보들이 서로 다른 형식과 구조, 이 기종의 컴퓨터 환견과 각기 다른 데이터 저장방식 또는 운용소프트웨어,네트웍 구조 등의 문제로 인하여, 문서교환에 의해 상호간의 정보를 공유하는 것이 현재의 실정이다. 문서교환에 의존하는 현재의 정보교환 방식은 과다한 서류의 중복작성 및 보관, 데이터의 부정확, 개발 납기의 지연과 같은 문제점을 갖게 된다.이러한 문제점 해결을 위해 제품개발에서 생산, 영업활동 전반에 걸친 정보 자동화 및 시스템들 상호간의 제품정보의 호환성 문제가 주요한 관심사가 되도 있다. 본 연구는 국제표준인 STEP 응용규약의 하나인 AP203(Application Protocol)을 이용하여 제품설계 정보 시스템을 구축하고자 한다.

The active participation and active interaction of learners in small group science inquiry activities are the main factors that determine the effectiveness of science learning. Roles can be assigned to members of a small group to facilitate interaction between members within the small group. The purpose of this study is to analyze the effect of role assignment on the types and patterns of verbal interactions in middle school students' small group science inquiry activities. For this, 172 students from middle schools located in metropolitan cities were surveyed. We analyzed 18 small groups with assigned roles and 15 small groups without assigned roles. The change in verbal interaction type in small group science inquiry activity according to role assignment was largely divided into alienation and participation. In the case of small groups with assigned roles, the participation type occupied a higher proportion than the alienation type. The change in verbal interaction patterns did not show much significant differences when the role was assigned in terms of cognitive and affective. Based on this, further research is needed on how role assignment affects verbal interactions depending on the type of scientific inquiry and the stage of inquiry. In addition, further research on the composition of small groups and role assignment is required.

This study explored whether story-based interactive music activities improve play interactions between children with developmental disabilities (DD) and typically developing (TD) children at an integrated daycare center, and whether these activities influence TD children's attitudes towards their DD peers. The participants included six children with DD, aged 3-5 years, and 21 TD peers. They attended 10 sessions, each 30 minutes, twice a week. Play interactions were observed during free play after each session, and TD children's attitudes towards peers with DD were assessed before and after the intervention. The results showed that children with TD and DD in the integrated group showed significantly reduced disengagement, with notable improvements in joint action for TD children and joint attention for DD children. However, there were no significant changes in peer acceptance among TD children in the integrated group while there was a significant decrease in the non-integrated group. This study highlights that story-based interactive music activities effectively enhance interactions between TD and DD children. However, the limited impact on peer acceptance suggests the need for more long-term and systematic interventions, considering the children's developmental levels. The study also emphasizes the importance of tailored approaches that address the individual needs of both TD and DD children, providing valuable insights into the direction of systematic interventions at a time when the importance of social integration is increasingly recognized.

Urban transport demand is derived from activity participation. A variety of individual daily activities based on the decisions on activity participation result in collective spatial behavior. The travel derived from the effort to overcome the spatially distributed locations of adjacent activities represents the detailed structural relationships among activities. An activity-based approach provides an important framework of analyzing contemporary urban daily life in the sense that it studies the interaction between individuals' daily decision making and social practice in time and space, on the one hand, and socio-spatial environment on the other. The current study identifies representative patterns of urban daily activity implementations and analyzes the correlation between representative patterns and individuals' characteristics and contextual characteristics. The study shows that urban daily activity patterns can be grouped in a limited number of representative patterns, which are systematically correlated with socio-spatial characteristics. The results provide related transportation policy implications.

In this article, we classify the middleschool students' mathematical modeling activities with three types as following: perceptive activity, cognitive activity, and metacognitive activity. And we research model development process through the interaction of perceptive, cognitive, and metacognitive activities. We report three results of our case study as following: First, students understanded the context of the modeling tasks on the base of their own experience and constructed the tasks with perceptive activity operating tool. Second, students developed various models with reorganizing cognitive activity which think and reason about perceptive activity-based model. Third, students were able to create generalizable and reusable models through metacognitive activities. This study revealed that the possible contribution of modeling activity as following. Students are able to understand abstractive mathematical knowledge as connecting between realistic activity and abstractive activity.

The aim of this study is to investigate the efficacy of pair/group work on the improvement of receptive and productive vocabulary knowledge. One hundred and twelve university students participated in the study and they were divided into three groups. Pair work group(n=42) performed three vocabulary activities in pairs as extra-class works, and Individual work group(n=38) did them alone. On the other hand, Group work group(n=32) did the activities in groups consisting of four or five people during the class. Data were collected from one pretest and two posttest scores. The results showed that collaborative group work was conducive to the growth of both receptive and productive vocabulary knowledge. In contrast, pair groups who do not work collaboratively gained least vocabulary knowledge among three groups. From collaborative group work, participants in higher proficiency levels made greater vocabulary gains than those at lower levels. Based on these results, pedagogical implications are discussed.

Recently, the necessities of gathering, producing, and sharing criminal information are critically important as intelligence functions of police agencies to improving public safety and national security. However, the inadequacies and barriers within which police agencies have in regard to intelligence functions impede criminal information gathering, intelligence producing within their agency, and intelligence sharing with other agencies. In this study, we analyzed informal networks constructed from a survey dataset of information and intelligence sharing among officers in police agencies. The results revealed the different structural properties of intelligence networks between police agencies. We did find that officers with high indegree and outdegree in a network played critical role on the dynamics and degree of intelligence gathering and assessment responsibilities. Finally, we could find evidence that the potential role of intermediary triggered relational dynamics for developing and sharing critical information among all police agencies.

The hypothesis of ridge subduction which explains the Cretaceous igneous activities in East Asia including China, Korea and Japan, has been widely accepted in the society. Especially, the hypothesis explains the southwest-to-northeast migration of the Cretaceous adakite emergence in Southwest Japan. However, the hypothesis has several issues because the geochemical analyses and plate reconstruction model are not consistent with the consequences of the ridge subduction. To resolve the issues, a new hypothesis of the plume-continent and plume-slab interaction is suggested, which explains the igneous activities during the Cretaceous. In this review, I briefly introduce the two hypotheses and suggest an additional future study to prove the new hypothesis.
