An issue of globalized and competitive business environment is a transformation of manufacturing strategy for rapidly product development. To copy with these trends, building up a market from various product is becoming conspicuous the core strategy of manufacture. Therefore, it is increasing of necessity for the environment of collaborative product development. As a part of corresponding for these demands, we propose the method that allows easy and rapid integration of legacy resources within the company and between departments. The proposed framework can easily construct a distributed environment for collaborative design between departments in the companies. It was implemented using CO<SUP>TM</SUP> based on DOME (Distributed Object-based Modeling Environment) that is knowledge based engineering solution.

This study examines the effects of corpus-based collaborative learning on the intake of grammar rules among high school students. This study is grounded on three theoretical backgrounds: Grammar teaching based on a large amount of input enhances intake; peer interaction promotes learners’ participation and has positive effects on their academic achievement; and discovery instruction stimulates learners’ motivation and helps them notice rules, leading to the conversion of input into intake. The subjects were divided into two groups, each group consisting of 60 students. The subjects studied six grammar rules over a period of six weeks. Group 1 did small group activities with the materials extracted from the COBUILD corpus, while Group 2 was given the teacher’s explanation of each rule with some examples designed to show how the target rule works. After each grammar lesson, both groups took a post-test. The results indicate that (a) corpus-based grammar learning helps engage learners in the learning process and raise their grammar awareness, (b) corpus-based learning facilitates noticing and identifying the target form better than its meaning and (c) peer interactions in a small group have positive effects on the intake of grammar rules.

The company was focusing on production which was partial mission rather than acquiring the information of customer in intensive process industry. The company accepted loss which is from over-production, losing of opportunity. After changing to Web environment, supply chain is more complicated and need of customer is more various. As a result the company hard works on controlling production rates, production quantities in production area and gathering exact information which is about available resource and available quantities. Cooperated demand planning have to get decreasing of inventory, improving of customer service in supply chain management. Specially demand planning that considers allocation of capacity is executed in Iron-Industry. Demand planning must be classified by customer, region and supply position level.

This paper presents a collaborative product development architecture (cPDA) using multi-agents which provides a framework for the design and analysis tools to effectively communicate and collaborate. This paper addresses two key issues. One is concerned with product visualization and real-time collaboration over the Internet. It discusses the light-weight geometric representation of the product information for efficient transmission and sharing over the Internet. The other is concerned with the collaborative process management using multi-agents. The collaborative product development process is globally managed by the process manager, but locally managed by agent interactions, which combines the advantage of the hierarchical management of the process with the heterarchical one.

이 연구는 상향식 교육과정 평가 모형을 개발하고 이를 적용하기 위한 협력적 실행 연구이다. 중앙 집중적인 교육과정 개발 체제를 따르는 우리나라의 상황을 고려해 볼 때, 교사는 교육과정 실행의 주체임에도 불구하고 국가 교육과정을 평가하고 이에 대한 개선 의견을 제안할 수 있는 공식적인 기회를 갖기 어려운 형편이었다. 이와 같은 문제의식에서 출발하여, 이 연구는 단위 학교 에서 현행 국가 교육과정을 평가하고자 할 때 적용할 수 있는 모형을 개발하고 이를 적용하였다. 연구자-참여자 간 협력을 통해 개발된 교육과정 평가 모형을 적용한 결과, 단위 학교에서 이루어지는 국가 교육과정 평가는 교사들이 국가 교육과정에 대한 이해와 참여의 필요성을 인식하는 계기를 제공하였고, 현장에 기반을 둔 유의미한 개선 의견을 도출하는 기회가 되었으며, 교육과정 제안자로서 국가 교육과정에 대한 ‘주인-되기’의 역동을 형성하는 과정임을 확인할 수 있었다. 연구 결과를 바탕으로, 이 글은 상향식 교육과정 평가 모형이 지속・확산되기 위한 향후 개선 과제를 제안하였다.

This study is about a design method for deriving task safety scenarios for the application of collaborative robots. A five-step process for deriving task safety scenarios for collaborative robots has been proposed, which focuses on the type of collaboration between human and collaborative robot. The three types of collaboration were classified according to the collaboration workspace and the worktime of human and collaborative robot. Based on these three types of collaboration, task safety scenarios include scenarios that predict risk from unintended use during work. Collaboration with collaborative robot is a human-centered process because human actions can create dangerous situations. Besides, we improved the understanding of this design methodology by presenting examples of the application of task safety scenarios according to the process for each type of collaboration.

최근 비대면 의사소통 기회가 많아지면서 영어 쓰기의 중요성이 점점 더 부각되고 있다. 본 연구의 목적은 대학 영어 작문에서 온라인 협력적 글쓰기 수업을 적용해보고 학생들의 인지적 및 정의적 영역에 대한 효과를 알아보려고 한다. 대학에서 연구자의 영어수업을 수강하는 학생들 가 운데 사전 쓰기 시험에서 통계적으로 유의한 차이를 보이지 않은 비슷한 수준의 두 개의 반으로 실험반과 비교반을 구성하여 온라인 협력적 글쓰기 수업을 실험반에 자기주도적 글쓰기 활동을 비교반에 적용하였다. 본 연구에서 채택한 방법은 실험연구로 두 반의 처치후 사후 비교를 통한 영어 쓰기 성취도의 변화를 살펴보았다. 연구 결과 전반적으로 실험반의 성과가 좋았으나 쓰기 하위 영역 전분야가 좋아진 것은 아니고 내용과 구조를 제외한 영어 쓰기의 하위 영역들인 문법, 어휘, 기계적 영역에서 의미 있는 결과가 나왔다. 정의적 태도와 관련해서 협력적 글쓰기 실험반의 전후 검사 결과 비교를 통해서 살펴본바 긍정적 태도보다는 부정적 태도의 감소에 의미 있는 결과 가 나왔고 특히 회피나 두려움의 감소와 관련해서 온라인 학습과 협력적 학습의 소집단 상호작용 이 도움이 되는 것으로 나타났다.

This study seeks to examine empirically the effect of leadership style on organizational commitment and organizational effectiveness. The data are from all departments of the undergraduate program at the State University in Central Java, Indonesia. The study comprises all divisions of the undergraduate program, which amounted to 207 people. The method for sampling is based on simple random sampling. Structural equation modeling (SEM) is applied in order to analyze the data. The results show that integrative adaptive leadership style has a positive effect on teamwork and affective commitment. Therefore, in order to improve teamwork, the organization should be assisted in completing the introduction of collaborative conflict resolution. Moreover, affective commitment positively affects organizational effectiveness. Thus, it can be said that efforts to improve the organizational effectiveness, should be supported by affective commitment. The study further revealed that integrative adaptive leadership style has a positive effect on teamwork. This means better execution of integrative adaptive leadership, higher level of coordination and vice versa. Each member has different responsibilities and duties, and it can be done or resolved in different ways. If the leader can accommodate the creativity of the faculty and staff, a solid team can be formed.

Collaborative Robot (Cobot) that can collaborate with humans by fusion with many advanced technologies among industrial robots in the industrial field are attracting attention. In this study, the engineers of Small and Medium Enterprises can directly participate in the cobot design, and ultimately, the possibility of deriving the shape design of the differentiated cobot was studied. The method applied to derive the shape design of differentiated cobot is ‘Morphological Analysis’. First, the design elements of the form of cobots were derived as ‘Link’ and ‘Joint’. In addition, by analyzing the image form of the Link and Joint of the existing cobot, a new form element of the Link and Joint was proposed. In order to quantitatively identify the most discriminating cobot shape design, FGI (Focus Group Interview) was conducted to derive image types of 4 Link and 3 Joint. Then, the most important ‘Shape Combination’ was carried out in morphological analysis, and 12 new cobot shape designs were drawn. Through this, the applicability of the morphological analysis method in the derivation of differentiated cobot shape design was examined.

Direct teaching is an essential function for collaborative robots for easy use by non-experts. For most robots, direct teaching is implemented only in joint space because the realization of Cartesian space direct teaching, in which the orientation of the end-effector is fixed while teaching, requires a measurement of the end-effector force. Thus, it is limited to the robots that are equipped with an expensive force/torque sensor. This study presents a Cartesian space direct teaching method for torque-controlled collaborative robots without either a force/torque sensor or joint torque sensors. The force exerted to the end-effector is obtained from the external torque which is estimated by the disturbance observer-based approach with the friction model. The friction model and the estimated end-effector force were experimentally verified using the robot equipped with joint torque sensors in order to compare the proposed sensorless approach with the method using torque sensors.

The purpose of this study was to analyze the status of conservation and management of KIAHS(Korea’s Important Agricultural Heritage System) by focusing on which of the conceptual and institutional characteristics and stakeholder activities, and to suggest improvement plans. The results were summarized as follows, first, insiders prioritize financial support and participate in plan execution and activities. Second, rural utilization and traditional agricultural succession activities and support are deficient. Third, administrators (intermediary) focuses primarily on KIAHS designation; ordinance enactment, manpower recruitment and other structural considerations are lacking. Fourth, the role of administrators (intermediary) is limited to operational funding and facility management support at the enforcement and activity stage. Fifth, outsiders besides visitors, such as the public or business enterprises, lacked participation methods. For the sustainable KIAHS, municipality must perceive agricultural heritage as a resource and recognize the importance, and treat it accordingly. The establishment of local-led conservation activities and movements must be considered in an enhanced investigation and excavation stage. The complementary policies that ensure continual support from experts from the first investigation and excavation stage to the final monitoring stage are necessary. The standards and regulations are necessary to achieve parity between conservation and maintenance of agricultural heritage, and its utilization.
