Management of today's dynamic projects requires a shift of focus from product to process. The purpose of traditional project controls is to conform performance to plan. The purpose of lean project controls is to make the best possible choices at each point in time during the course of the project, as well as contributing knowledge to the parent organizations so they can learn from project experience. The Lean Construction Institute(LCI) proposed the Last Planner System(LPS) capable of accomplishing that purpose, principally through controlling the quality of planning and of management processes themselves, as distinct from concentrating exclusively on project performance. The case project was a pilot project for the implementation of the Last Planner. Consequently, the coordination of the work on this project was extremely successful. The project had its share of challenges. The coordination did not prevent design problems, or supplier errors, but helped the team deal with the problems effectively while maintaining the work flow. The last planner helped the contractors know: a) who will be doing what and where, b) what each one needs from the others, and c) what are the project priorities. The system itself created a more collaborative environment, because it 'demands' that the subcontractors address these issues.

The most of elementary school science textbook contents are composed of observation and experiment activities. When students study natural phenomena, observation and experiment are st rongly emphasized to improve understanding of scientific concepts and inquiry abilities. The purpose of this study is deep understanding about experimental science classes. This ethnographic study is conducted by observations of experimental science classes in natural setting and interviews of teachers, students of the 5th grade. The conclusions of this study are as follows: First, the general process of the elementary science experimental classes is 'identifying learning purposes -1 planning experiments -1 predicting the results -1 experimenting-t summarizing the results.' The experiments are conducted by group activities and the teachers conceived that the me st difficult step considered by students is 'planning experiments'. Second, students like hands-on activities, but they feel difficulty on less guided experiments. Students perform results oriented-activities. Third, in group activities, students prefer to work with the same gender or collaborative peers.

Contemporary lectures in undergraduate engineering courses typically focus on teaching major technical knowledge-based theories in a limited time. Therefore, most lectures do not allow the students to gain understanding of how the theories are applied, especially in Naval Architecture and Ocean Engineering departments. Shipyards require students to acquire practical ship design skills in undergraduate courses. To meet this requirement, two lectures are organized by the authors; namely, "Planning Procedure of Naval Architecture & Ocean Engineering" (PNAOE) and "Innovative Ship Design" (ISD). The concept of project-based and collaborative learning is applied in these two lectures. In the PNAOE lecture, sophomores receive instruction in the designing and building of model ships, and the students' work is evaluated in a model ship contest. This curriculum enables students to understand the concepts of ship design and production. In the ISD lecture, seniors learn how to develop their creative ideas about ship design and communicate with members of group. They are encouraged to cooperate with others and understand the ship design process. In the capstone design course, students receive guidance to facilitate understanding of how the knowledge from their sophomore or junior classes, such as fluid mechanics, statics, and dynamics, can be applied to practical ship design. Students are also encouraged to compete in the ship design contest organized by the Society of Naval Architects of Korea. Moreover, the effectiveness of project-based and collaborative learning for enhancing interest in the shipbuilding Industry and understanding the ship design process is demonstrated by citing the PNAOE and ISD lectures as examples.

A ship-block cutting module is being developed as part of a computational system for a ship design. The module supports product-information to other modules in design process and displays ship-blocks in cutting-operation. Welding-information is essential to process-planning and scheduling. In the module, ship-blocks are modeled by Plate-Objects and then divided into several cutting pieces. The module automatically creates Welding-Objects containing welding-information in the process. Since the module is connected to WWW(World Wide Web), users in various platforms can access the models simultaneously In addition, users can check manufacturing constraints by inspecting a virtual model.

Impact of business process re-engineering requires the fundamental rethinking of how information systems are analyzed and designed. It is no longer sufficient to establish a monolithic system for fixed business environments. Information systems must be adaptive in nature. This demand is also applied in production domain. Enabling concept for the adaptive information system is reusability. This paper presents a new object-oriented analysis process for creating such reusable software components in production domain, especially for production planning and scheduling. Our process called MeCOMA is based on three meta-models: physical object meta-model, data object meta-model, and activity object meta-model. After the three meta-models are extended independently for a given production system, they are collaboratively integrated on the basis of integration pattern. The main advantages of MeCOMA are (1) to reduce software development time and (2) to consistently build reusable production software components.

목적 : 학교기반 작업치료는 교육전문가와 협업하는 다전문가적 접근이 필요하다. 본 연구는 일반 초등학교에 진학하는 고위험군 아동들을 대상으로 특수교사와 작업치료사가 함께 지역사회 기관에서 협업으로 실시하는 집단교육 시간의 작업수행변화를 분석하고, 감각통합 중재의 의미를 파악하고자 하였다. 연구방법 : 예비 프로그램으로 입학준비 프로그램을 특수교사와 작업치료사의 부분적인 협업을 통해 실시한 후, 초등학교 적응프로그램은 특수교사와 작업치료사가 전체과정을 협업하여 시행하였다. 연구대상은 6명이었다(7세 5명, 9세 1명). 프로그램 평가는 교육활동 참여에 대해 School AMPS를 실시하였고, 일정하게 구성된 자조활동에 대해 AMPS 수행기술을 관찰하여 중재전략에 활용하였다. 평가를 통한 중재전략과 그에 따라 진행된 변화를 교사와 치료사의 월간 기록을 토대로 질적 분석을 실시하였으며, 부모설문을 통해 감각프로파일을 조사하였다. 결과 : 사전 프로그램에 참가한 아동 5명 중 4명이 감각통합적인 어려움으로 수행에 영향을 받는다고 평가되었고, 이 결과가 본 프로그램 구성에 기반이 되었다. 본 프로그램 구성은 참가 아동이 속한 학년의 교실에서 수업과제(school task)와 집단 활동, 기본 자조활동으로 이루어졌고, 수업과제활동평가 School AMPS는 통계적으로는 유의미하지 않으나 평균 운동기술은 0.14 로짓(logit), 평균처리기술은 0.07 로짓이 향상되었다. 협업적 중재로는 감각 통합이 주된 회복적 중재로 사용되었고, 과제수행을 통해 직접 어려움이 있는 기술을 향상하는 습득적 중재, 교사의 대응전략이나 도구 및 환경 조정을 시행하는 보상/적응적 중재가 적용되었다. 기본적 자조활동들은 도움이 필요한 수준에서 자립적인 수준으로 향상되어서 반복적인 자조활동의 경험과 중재가 효과적이었다. 그러나 개선된 수행기술들 이외에 새롭게 도전이 되는 수행기술이 발생하였고, 이런 문제들은 감정과 행동문제와 더불어 감각통합의 어려움 뿐 아니라 집단에서 일어나는 역동적 이유 때문으로 평가되었다. 결론 : 초기에는 감각통합 프로그램을 통하여 학생들의 참여가 향상될 수 있었다. 그러나, 집단 활동을 통해서 드러나는 초등학생들의 감정조절 문제, 역할 변화에 따른 수행변화, 또래에 대한 반응문제가 드러남에 따라 감각통합적인 중재에서 더 복합적인 개인-환경-과제에 대한 중재가 필요하였다. 특수교사와 작업치료사의 협업은 상호보완적이며 필요한 수행기술을 향상하는 데 시너지 효과가 있었다. 이 과정에서 School AMPS는 측정 가능한 결과를 일부 제시하는 데 유용하며, 향후에는 질적 분석을 보다 객관화 할 수 있는 방법들이 요구된다.

The current challenge with which most shipyards are forced is to reduce the design time and the time-to-delivery because of explosive order of shipbuilding. Collaborative design and product data management have become important to reduce the lead time. Furthermore, enterprise information technologies such as ERP (Enterprise Resource Planning), SCM (Supply Chain management), and APS (Advanced Planning System) requires the collaborative environment. Also, manufacturing environment has been considered as a topic of strategic interest to get shorter product lifecycles in shipyards. Most shipyards have chosen an environment of ETO (Engineering To Order) strategy which designs and produces new products in response to various requirements of customer, rules and regulations. In the ATO (Assemble 10 Order) environment, most component parts have been designed to be procured or produced on the order requirement. The basic distinction between the ETO and ATO is the timing of the design. Thus in the ATO environment, it is more flexible in reducing the lead time to meet the specified requirements of customers. However, the ETO strategy requires new ship design process and ship product structures that are linked with the implementation of PLM. And, the function and architecture of current PLM solution has been designed based upon ATO environment properly. This paper presents the PLM architecture which effectively reflects the characteristics of shipbuilding. 4-layer architecture model is suggested to implement the PLM system. Also, implemented functions of ship PLM is explained in order to make a practical guidance for ship PLM implementation.
