Co-operative (Co-op) education is a college program that integrates classroom studies with paid, productive and real-life work experience. A mandatory Co-op program for the degree is introduced with a sample curriculum from the Mechanical Engineering program at University of the Pacific. The mandatory Co-op program requires a minimum of 7 months of work experience with the option of pursuing a 12 month program. Students also have the opportunity of participating in an Engineering Industry Fellowship (EIF) program or an International Engineering Co-op program (IECP). University of the Pacific has engineering programs in Bio-Engineering, Civil Engineering, Computer Engineering, Electrical Engineering, Engineering Management, Engineering Physics, and Mechanical Engineering. All the programs are ABET-accredited except the Bio-Engineering program, which is relatively new. The Co-op employers evaluate the Co-op students at the end of the working period before returning to school, and the students also provide an evaluation of their Co-op experience. Co-op employer evaluations of student work are used in ABET assessment methods developed by the Mechanical Engineering program at University of the Pacific.

Nagra was established in 1972 by the Swiss nuclear power plant operators and the Federal Government to implement permanent and safe disposal of all types of radioactive waste generated in Switzerland. The Swiss Nuclear Energy Act specifies that these shall be disposed of in deep geological repositories. A number of different geological formations and sites have been investigated to date and an extended database of geological characteristics as well as data and state-of-the-art methodologies required for the evaluation of the long-term safety of repository systems have been developed. The research, development, and demonstration activities are further supported by the two underground research facilities operating in Switzerland, the Grimsel Test Site and the Mont Terri Project, along with very active collaboration of Nagra with national and international partners. A new site selection process was approved by the Federal Government in 2008 and is ongoing. This process is driven by the long-term safety and feasibility of the geological repositories and is based on a step-wise decision-making approach with a strong participatory component from the affected communities and regions. In this paper a brief history and the current status of the Swiss radioactive waste management program are presented and special characteristics that may be useful beyond the Swiss program are highlighted and discussed.

최근 들어 졸업생의 취업 경쟁력 강화, 기업친화형 우수 인재 확보, 대학 내 산학협력 활성화를 위한 수단으로 Co-op 교육(장기현장실습) 중심의 산학협력교육에 대한 중요성이 부각되고 있다. 지금까지 우리나라 대학들은 전공연계성과 취업연계성이 낮은 단기 인턴십 위주의 현장실습 프로그램을 주로 운영해 왔다. 이러한 문제점에 대응하여, 정부는 현재 '현장실습 운영 지침' 제정을 추진하고 있으며, 장기현장실습 시범대학을 선정하는 등 장기현장실습 중심의 산학협력교육 활성화를 위해 노력하고 있다. 산학협력교육의 제도적 활성화를 위해서는 이 제도를 오랫동안 시행해 온 북미와 유럽의 대학들에 대한 다양한 사례 연구가 축적될 필요가 있다. 이를 위해 본 연구에서는 미국의 센트럴워싱턴대학교(CWU)를 사례로 하여 Co-op 교육의 운영 실태를 중심으로 분석하고, 산학협력교육 활성화를 위한 정책적 함의를 제시하였다. 사례 연구의 주요 분석 결과는 다음과 같다. 첫째, CWU 학생들은 주로 좁게는 카운티 내, 넓게는 워싱턴 주 내에서 현장실습을 수행하고 있으며, 실습을 했던 기관으로 취업을 하는 경우가 많아, 현장실습의 지역연계성이 높은 것으로 나타났다. 둘째, CWU의 현장실습 프로그램은 전공연계성이 높고, 특히 인문사회, 예체능, 사범계열의 학생들의 현장실습이 활발한 것으로 나타났다. 셋째, 실습 참여 학생의 자격조건은 엄격한 대신, 전공 특성에 따라 유연하게 현장실습 프로그램을 운영하고 있다. 이러한 분석 결과를 토대로 하였을 때, 우리나라 대학들의 현장실습 프로그램 또한 전공연계성, 취업연계성, 지역연계성을 높이는데 초점을 둘 필요가 있고, 대학 및 전공의 특성에 따라 유연하게 운영할 필요가 있다고 판단된다.

Generally, a PLM education program in university consists of lectures of theory, software lab and software development raining as an advanced subject. Most industries want more than these, such as practical problem solving capabilities, teamwork skills and engineering communications including human relationship, rhetoric, technical writing, presentation and etc. Problem-Based Learning is a problem-stimulated and student-centered teaming method, and an innovative education strategy for collaborative and self-directed learning by applying real world problems. Education paradigm changes from "teaching" to "learning" accomplished by team working, and students are encouraged to develop, present, explain and defense their ideas, suggestions or solutions of a problem, and the "cooperative teaming" proceeds spontaneously during team operations. Co-operative education program is an into-grated academic model and a structured educational program combining classroom learning with productive work experience in a field related to a student's academic or career goals. Based on the partnership between academic institutions and industries, students are engaged in real and productive "work" in the industry, in contrast with merely observing. In this paper, PBL with Co-op program is suggested as an effective approach for PLM education, and we made and operated a PBL-based education course with industry co-op program. The Co-op education in industry accompanied with the PBL course in university can improve practical problem solving capabilities of students, including modeling and management of P3R(Product, Process, resource and Plant) using commercial PLM software tools. By the result, we found this to be an effective strategy for helping students, professors and industries succeed in engineering education, especially PLM area.

본 논문에서는 한국기술교육대학교가 공학교육의 새로운 혁신모델로 도입예정인 산학관연계 장기현장실습(IPP) 제도에 대해 제안하고 주요사항에 대해 논의한다. IPP 제도는 기존 단기 현장실습 제도의 문제점을 보완하고 100년의 장기현장실습 역사를 갖고 있는 북미의 co-op (co-operative education) 모델을 벤치마킹하여 대한민국 학제시스템에 적합하게 설계한 한국형 co-op 모델로 특히 기존의 co-op 시스템과 달리 정부(고용노동부)가 산학간의 협력교육을 적극 지원하는 제도이다. 제안하는 IPP 제도가 성공하기 위해서는 무엇보다도 기업의 대학교육에 대한 적극적인 참여와 open mind가 필요하며, 대학은 체계적인 학사시스템 설계 및 IPP 센터 등 인프라 구축이 선행되어야 한다.

A probabilistic assessment code, PRO-LOCA ver. 3.7 which was developed in an international co-operative research program, PARTRIDGE was evaluated by conducting sensitivity analysis. The effect of some variables such as simulation methods (adaptive sampling, iteration numbers, weld residual stress model), crack features(Poisson's arrival rate, maximum numbers of cracks, initial flaw size, fabrication flaws), operating and loading conditions(temperature, primary bending stress, earthquake strength and frequency), and inspection model(inspection intervals, detectable leak rate) on the failure probabilities of a surge line nozzle was investigated. The results of sensitivity analysis shows the remaining problems of the PRO-LOCA code such as the instability of adaptive sampling and unexpected trend of failure probabilities at an early stage.

Background: Carbonate apatite ($CO_3Ap$) and silica-calcium phosphate composite (SCPC) are bone substitutes with good prospect for dental application. SCPC creates a hydroxyapatite surface layer and stimulate bone cell function while, $CO_3Ap$ induce apatite crystal formation with good adaptation providing good seal between cement and the bone. Together, these materials will add favorable properties as a pulp capping material to stimulate mineral barrier and maintain pulp vitality. The aim of this study is to investigate modification of $CO_3Ap$ cement combined with SCPC, later term as $CO_3Ap-SCPC$ cement (CAS) in means of its chemical (Calcium release) and physical properties (setting time, DTS and pH value). Methods: The study consist of three groups; group 1 (100% calcium hydroxide, group 2 $CO_3Ap$ (60% DCPA: 40% vaterite, and group 3 CAS (60% DCPA: 20% vaterite: 20% SCPC. Distilled water was employed as a solution for group 1, and $0.2mol/L\;Na_3PO_4$ used for group 2 and group 3. Samples were evaluated with respect to important properties for pulp capping application such as pH, setting time, mechanical strength and calcium release evaluation. Results: The fastest setting time was in $CO_3Ap$ cement group without SCPC, while the addition of 20% SCPC slightly increase the pH value but did not improved the cement mechanical strength, however, the mechanical strength of both $CO_3Ap$ groups were significantly higher than calcium hydroxide. All three groups released calcium ions and had alkaline pH. Highest pH level, as well as calcium released level, was in the control group. Conclusion: The CAS cement had good mechanical and acceptable chemical properties for pulp capping application compared to calcium hydroxide as a gold standard. However, improvements and in vivo studies are to be carried out with the further development of this material.

This paper presents a cooperation strategy between a human operator and autonomous robots for an interactive robot soccer game, The interactive robot soccer game has been developed to allow humans to join into the game dynamically and reinforce entertainment characteristics. In order to make these games more interesting, a cooperation strategy between humans and autonomous robots on a team is very important. Strategies can be pre-programmed or learned by robots themselves with learning or evolving algorithms. Since the robot soccer system is hard to model and its environment changes dynamically, it is very difficult to pre-program cooperation strategies between robot agents. Q-learning - one of the most representative reinforcement learning methods - is shown to be effective for solving problems dynamically without explicit knowledge of the system. Therefore, in our research, a Q-learning based learning method has been utilized. Prior to utilizing Q-teaming, state variables describing the game situation and actions' sets of robots have been defined. After the learning process, the human operator could play the game more easily. To evaluate the usefulness of the proposed strategy, some simulations and games have been carried out.
