The purpose of this study was to extract an u-PBL support system core value and design strategy based upon field experience learning. To accomplish this the study, first of all, analyzed the core values, design strategy which was selected after needs analysis and literature review of theories and cases regarding the PBL, e-PBL, blended-PBL, Field experience learning based on ubiquitous environment, and learning model based on ubiquitous technology. This study identified the three core values as; systemic support for instructional activity, just in time support for instructional activity and support for interaction facilitation. As further research areas, it might be useful to develop u-PBL instructional support system based upon the model designed from this study. Also, research concerning the verification of the model based upon implementation of the program case might be necessary.

본 연구는 문제중심학습(PBL)의 수업 효과를 촉진하기 위한 전략으로 팀 퍼실리테이션 프로그램 적용 후 팀 활동 역량에 미치는 효과를 확인하기 위해 팀 역동성을 측정한 융합연구이다. 연구방법으로 실험군에게는 팀 퍼실리테이션 프로그램을, 대조군에게는 인간관계 프로그램을 적용한 후 효과를 분석하였다. 연구결과, 팀 퍼실리테이션 프로그램을 교육 받은 실험군이 인간관계 교육을 받은 대조군보다 팀 활동을 위한 개인기여 역량(F=5.12, p<0.05), 팀원들의 팀 역동성(F=10.35, p<0.01)에서 통계적으로 유의한 차이를 보였고, 팀 역동성 항목 중 팀원 간 신뢰(F=9.86, p<0.01), 의사소통(F=5.69, p<0.05), 팀 학습행동(F=4.57 p<0.05)이 통계적으로 유의한 차이가 있었다. 연구 결과, PBL 수업에서 팀 퍼실리테이션 프로그램이 팀 역동성을 촉진하였다는 것을 알 수 있었다. 향후 PBL과 같은 소그룹 협동 학습에서 팀 역동 활성화에 필요한 교육적 프로그램을 사전에 적용할 필요성이 있다.

Target Costing research has a long history in the study of management control systems. However, there is very little published empirical analysis studies on Target Costing. This study investigate the impact of Target Costing practices on organizational performance. This study uses survey responses from executive at 125 Target Costing practicing firms to better understand the benefits that firms have experienced through Target Costing adoption and whether a more comprehensive implementation is worthwhile. The research results demonstrate that Target Costing has a positive and significant relationship with low cost, efficiency of R&D, and interaction facilitation. In particular, there is significant and positive relationship between organizational structure and performance. This study indicate that Target Costing is a vital management strategy to build and sustain competitive advantage.

Wireless power transfer (WPT) technology has the advantages of intelligence and facilitation. This paper designs a WPT system applied to battery charging and provides a strategy which switches from the constant current (CC) charging mode to constant voltage (CV) charging mode. The LCL-LCL topology is used to realize the CC output, while the LCL-S (series compensation) topology is used to realize the CV output. The main factor affecting the output characteristics is extracted by analyzing the two topologies above. Based on the main factor, this paper puts forward a modified way to design the system. In addition, on-line monitors for the battery and switches are placed at receiving side, which avoids the need for introducing an information interaction module into the system. Therefore, the complexity of the controlling system is reduced. Finally, simulation and experimental analyses are carried out to verify the correctness of the compound topologies.

PURPOSE: This study aimed to utilize the International Classification of Functioning, Disability, and Health (ICF) tool to identify a problem list and explore intervention effects using proprioceptive neuromuscular facilitation (PNF) for improving the crosswalk performance of patients who have undergone a bilateral hip arthroplasty. METHODS: The subject of this study was a 43-year-old male who had undergone a bilateral hip arthroplasty. To address the subject's functional status, a clinical decision-making process was carried out in the order of examination, evaluation, diagnosis, prognosis, intervention, and outcome. Patient information during the examination was collected using the ICF core set. The evaluation involved listing the items of each problem using the ICF assessment sheet and identifying the interaction between activity limitations and the impairment level. The diagnosis explicitly described the causal relationships derived from the evaluation using ICF terminology. The prognosis presented activity goals, body function, and structured goals in terms of the activity and participation levels that needed to be achieved for an individual's functional status. The intervention approached problems through the four components of the PNF philosophy, namely basic principles and procedures, techniques, and patterns, in an indirect-direct-task sequence. Results were compared before and after the intervention using the ICF evaluation display. RESULTS: The results of the study showed that the primary activity limitation, which was the walking time across the crosswalk, showed improvement, and the trunk's counter rotation and the weight-bearing capacity of both the lower limbs, which were impairment level indicators, were enhanced. CONCLUSION: This study suggests that PNF intervention strategies will serve as a positive approach for improving crosswalk walking in patients with bilateral hip arthroplasty.

PURPOSE: This study was conducted to investigate the intervention effect obtained by applying an ICF tool to improve the dressing in a patient with rotator cuff syndrome to schematize the problems and approaching with PNF to solve the problems. METHODS: The subject of this study was a 44-year-old patient who underwent surgery after complete right rotator cuff tear. To treat his symptoms, the processes of clinical practice were implemented in the order of examination, assessment, diagnosis, prognosis, intervention, and outcome. During examination, patient information was collected using the ICF core set. In the assessment, the problems were schematized, and an ICF assessment sheet was used to identify the interaction of the problems. The diagnosis was made by clearly describing the causal relationship derived from the assessment in ICF terms. To solve the problems, the intervention was given in the order of indirect, direct, and task based on the philosophy of PNF. To evaluate the outcome, the differences before and after the intervention were compared. Additionally, the comparison for the ICF qualifier is presented with the ICF evaluation display. RESULTS: The results of the study showed clinical advantages in shoulder strength, eccentric control, range of motion, scapular stability, and shoulder pain. Overall, our patient with rotator cuff syndrome showed improvement in dressing and undressing activity in response to the PNF strategy. CONCLUSION: Application of the PNF intervention strategy after complete rotator cuff tear would have a positive effect on patient upper extremity function.

본 연구는 보육교사가 사용하는 유아의 또래 상호작용 촉진 전략에 대한 사용실제를 알아보고, 전략실행시 교사들이 겪는 어려움을 복합연구법을 사용하여 살펴보았다. 연구대상은 서울경기 지역의 보육교사 155명으로, 상호작용촉진 전략사용실제에 관한 SIPPY 설문조사에 응답하였다. 구체적 전략 실제와 전략 사용시 겪는 어려움을 알아보고자 서면질문 조사를 실시하여 설문참가자중 44명이 응답하였고, 이중 3명을 대상으로 심층면접을 실시하였다. SIPPY 설문자료는 SPSS 20.0을 사용하여 기술통계와 일원분반분석을 사용하여 분석하였으며, 서면질문과 심층면접자료는 질적 연구방법 절차를 사용하여 분석하였다. 연구 결과는 다음과 같다. 첫째, 본 연구의 보육교사들은 또래 상호작용 촉진 전략 중 환경구성 전략과 일상활동 전략을 대체적으로 자주 사용하며, 상대적으로 중점활동 전략은 적게 사용하는 것으로 나타났다. 또한 경력과 학력에 따른 전략사용에서 통계적으로 유의한 차이를 보였다. 둘째, 구체적 전략사용실제를 분석한 결과, 보육교사들은 칭찬, 시범, 제안, 매체활용과 같은 일상활동 전략을 자주 사용하며, 상호작용 촉진 전략 사용 시 환경적 요인, 가정과의 연계, 유아개별 특성, 교사요인 등이 또래사용 촉진 전략 사용을 어렵게 하는 요소들로 분석되었다. 연구결과를 바탕으로 유아 또래 상호작용 증진을 위한 전략사용의 확대방안 및 지속적인 교사전문성 발달 프로그램의 개발에 관한 제언이 제시되었다.
