Objectives: In this study, we aimed to develop a systematic tool that can evaluate the effects of interprofessional education (IPE) by applying four core competencies (values/ethics for interprofessional practice, roles/responsibilities, interprofessional communication, and teams and teamwork) and an educational evaluation model to evaluate the learning, behavior of learners, and results step by step. Methods: Previous studies on IPE evaluation tools were analyzed, and an evaluation tool (draft) was developed by modifying questions suitable for evaluation according to the Kirkpatrick model's stages and core competencies. The evaluation tool was completed by conducting a Delphi survey twice with 4-6 experts. To analyze the Delphi survey, the content validity index (CVI) was calculated, and the reliability coefficient (Cronbach's alpha coefficient) was used to measure reliability. Results: 29 questions on pre-education, consisting of learning and behavior stages, and 54 questions on post-education, consisting of reaction, learning, behavior, and results stages, were developed. The CVI and Cronbach's alpha coefficient values were >0.8 and >0.6, respectively. Conclusions: The IPE evaluation tool developed in this study is expected to contribute to the evaluation of the educational level of IPE and the identification of points for improvement when applied to various educational settings.

본 연구는 현대사회의 부모양육행동은 사회문화적 환경의 시대적 변화를 반영하여 변화되어야 한다는 연구의 필요성에 근거하여 시도되었다. 따라서 기존의 부모양육행동과 비고츠키의 사회구성주의적 아동발달 관점에서의 양육행동을 비교 분석하였다. 이를 위하여 근접발달단계에 있는 아동들의 성장과 발달을 촉진할 수 있는 사회구성주의적 부모양육행동을 분석하여 양육행동의 핵심요인으로 비고츠키 이론의 핵심요인을 탐색하였다. 연구방법으로는 비고츠키 이론을 중심으로 한 연구들을 분석하여 요인을 추출한 후 비고츠키 이론에 관한 전문가 3명의 타당화 작업을 통하여 내용타당성을 확인하였다. 연구결과, 첫째, 사회적 상호작용에서의 협력적 상호작용 요인 둘째, 사회적 구성행동에서의 내면화 강조 요인 셋째, 근접발달영역에서의 잠재성 계발 요인 넷째, 중재적 매개체로서의 교육적 대화 요인 다섯째, 스캐폴딩(scaffolding)으로서의 조력설정 요인이 추출되었다. 본 연구의 결과는 부모양육행동의 새로운 패러다임으로써, 사회구성주의적 부모양육행동 척도를 개발하는데 새로운 시도를 마련했다는 점에서 연구의 큰 의의를 갖는다.

Extrusion characteristics of Mg alloys were studied experimentally. The Al-Zn-Mg alloys, AZ31, AZ6l, AZ80, and AZ91 were extruded with hot hydrostatic extrusion process. The hydrostatic process was efficient to reduce surface friction and extend steady state region in extrusion which made it more convenient to examine deformation behavior of the alloys avoiding the disturbance caused by temporary contact state between billet and die, and billet and container. High pressure was cooperative to expand forming limit of the alloys which were applied on the billet during the extrusion process. Extrusion limits were traced in temperature and extrusion speed domain with changing composition of the alloying elements. Effects of process parameters on extrusion load and microstructure evolution were investigated also.

A control system design based on coupled nonlinear oscillators (CNOs) for a self-organized swarm system is presented. In this scheme, agents self-organize to flock and arrange group formations through attractive and repulsive forces among themselves using CNOs. Virtual agents are also used to create richer group formation patterns. The objective of the swarm control in this paper is to follow a moving target with a final group formation in the shortest possible time despite some obstacles. The simulation results have shown that the proposed scheme can effectively construct a self-organized multi-agent swarm system capable of group formation and group immigration despite the emergence of obstacles.

클라우드 컴퓨팅은 새로운 컴퓨팅 기술이고 조직에서는 정보자원을 전략적으로 관리할 수 있게 하는 수단을 제공한다. 사용자 관점에서 클라우드 컴퓨팅은 원격의 어플리케이션에 접근하고, 데이터를 저장하며, 개인간 협업을 지원하는 등의 이슈를 수반한다. 조직에서 클라우드 컴퓨팅 효과적으로 적용되기 위해서는 우선 사용자의 채택이 전제조건이다. 본 논문에서 우리는 개인차원의 클라우드 컴퓨팅 수용을 설명하기 위하여 기존의 UTAUT 모형을 수정하고 확장한 모형을 제안하고, 설문 데이터를 이용하여 이 모형의 타당성을 검정한다.

Every country finds a way to respond a lot of terrors to keep her safe in many ways. Our country, before a terror outbreaks, makes various countermeasures such as strengthening international cooperative systems, strengthening informational ability to countermeasure terror, restricting for terrorists to enter or exit from our country, restricting other countries to input weapons in our country to prevent from terror in the aspect of precaution. A terror is more grave than any other one in behavior, and the criminals have to be punished so much and be discriminated from other ones, too. So, a concept of general crime and terror has to be defined. It is finished in the academic area to some extent, but, it is not sufficient in lawful area so much. Afterwards, it is necessary to establish counter-terror protection laws regulating terror crimes directly. In addition, it is necessary to define concretely and clearly the terror activity and deduce the definition of terrorism.

Reinforcement learning if a kind of machine learning. It aims to adapt an agent to a given environment with a clue to a reward and a penalty. Q-learning [8] that is a representative reinforcement learning system treats a reward and a penalty at the same time. There is a problem how to decide an appropriate reward and penalty values. We know the Penalty Avoiding Rational Policy Making algorithm (PARP) [4] and the Penalty Avoiding Profit Sharing (PAPS) [2] as reinforcement learning systems to treat a reward and a penalty independently. though PAPS is a descendant algorithm of PARP, both PARP and PAPS tend to learn a local optimal policy. To overcome it, ion this paper, we propose the Multi Best method (MB) that is PAPS with the multi-start method[5]. MB selects the best policy in several policies that are learned by PAPS agents. By applying PS, PAPS and MB to a soccer game environment based on the SoccerBots[9], we show that MB is the best solution for the soccer game environment.

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.

A bucket-brigade is a way of transporting items where items are passed from one person to the next. The operation of the bucket brigade imitates the cooperative behavior of ants when brood, food or other resources are moved. Koo (2009) presented a bucket brigade-based assembly cell where each worker follows a simple rule: perform assembly operations on a product until the next worker downstream takes it over; then go back to the previous worker upstream to take over a new assembly job. In this way, the flow line is self-balanced without any predetermined job assignment. However, there are some productivity losses related to hand-off and blocking. This paper examines the hand-off and blocking losses and presents a new bucket brigade-based assembly cell where working areas for each assembler is restricted with the help of buffer interfaces. Simulation experiments are used to validate the performance of the new assembly system.

In this paper, we propose the coordination scheme in a single-manufacturer-multiple-retailer supply chain system. Traditionally, the bargaining power of the single manufacturer is superior to those of retailers. The business environment supported by the e-business scheme may give rise to new business behavior. The multitude of retailer requests the manufacturer to relax the his unilateral lot-sizing policy while they are willing to compensate more than the manufacturer's expected loss caused by abandon his superior bargaining power. The side payment aggregated by the multiple retailers is transferred to the manufacturer according to the degree of the manufacturer's relaxation from the current unilateral lot-sizing policy.
