The ICC is amending international trade rules such as Incoterms to respond to periodically changing international trade environments. Moreover, a drafting group has been formed for developing the eighth amendment and the Incoterms. Due to the recent development of information and communication technology, interest in smart work is increasing globally. Smart work is a concept that enables works to be performed without time and space constraints, and the mobile office is a typical form of smart work. Smart work has brought significant changes to the way that workers perform their jobs, and it has considerable impacts on international trade transactions. This study examines the impact of the development of information and communication technology on electronic trade customs and analyzes the revision process of Incoterms for electronic document informatization. Also, we provide implications for the 8th amendment of Incoterms.

본 논문은 최근 다양한 사회 분야에 있어서 IT 기술이 적용되는 과정을 SD 모델링 방식을 사용하여 연구한 경험과 발견을 서술하고자 한다. 모델의 초기 단계에서 우리는 다양한 사회 분야마다 다른 SD 모델을 만들 것이냐 아니면 기본적으로 유사한 모델 구조를 취할 것이냐를 선택해야 했다. 사회 분야마다 다른 구조의 SD 모델을 만들면, 상호간의 구조와 시뮬레이션 결과를 비교하기 어렵다. 하지만 상호 모델 구조를 유사하게 구축하려고 하니, 서로 다른 모델링 팀들간의 의사소통에 노력과 시간 소비가 지나치게 커져 갔다. 이러한 어려움을 극복하기 위하여 본 연구에서는 시스템 다이내믹스 모델링에도 시스템 사고의 원형적 피드백 루프에서와 같은 원형적 SD 모델을 만들고, 이를 사회 각 분야에 적용하는 방식을 취하고자 하였다. 먼저 최근 IT 기술 발전을 이끌어 가는 핵심적인 요소로서 클라우드 컴퓨팅, 스마트 기기, 사물 인터넷을 선정하고 이들간의 상호 관계성을 표현하는 SD 모델을 만들었다. 이를 원형(archetype)으로 하여, 교육, 의료, 원격 근무 등 사회 각 분야의 IT 확산 과정에 적용하여 모델링을 하고 시뮬레이션을 하여 상호 비교하면서 정책 시사점을 논의할 수 있었다. 본 논문에서는 이 중에서 원격 근무(smart work)에 관한 적용 사례를 제시함으로써, SD 모델링에 있어서 원형적 접근 방법의 가능성을 탐색한다.

This research conducted empirical and comparative study following interview concerning the relationship of acceptance attitudes and expected effects of the teleworking between Korean and Canada organizations. Independent variable was acceptance attitude, and the expected effect as dependent variable. Totally, 201 responded questionnaires (Korea : 118, Canada : 83) were analyzed for multiple regression and mean difference between groups. On January 1, 2015, Canada had agreed FTA (free trade agreement) with Korea. Therefore, many organizations can have opportunities for sharing hands in social infrastructures and business area. As a result, the research found out that teleworking can positively improve employee's quality of life, efficiency of works. Moreover, respondents informed us that it may give us national and social cost saving. The BYOD (bring your own device) will be helpful to make employees do more active communication. This comparative research expects that two countries have some insights to cooperate in smart work or teleworking. In addition, several Korean companies can have chances to export IT technologies to Canada market.

This study started from the practical need for a career experience program in the fashion major that is creative and responds to current methodologies. The purpose of this study is to propose a fashion work experience program that combines digital technology and practical experience. The research methods and procedures were as follows: fashion items and wearable devices were selected, the LED smart bag program was developed, and it was executed. A total of 123 students participated in the program, and a satisfaction survey was conducted after observation and oral evaluation. All of the participants completed the LED smart bag processes of design ideation, material selection, production, and styling using an eco-bag (one of the fashion items and as an LED wearable device). As a result of the participants' satisfaction (on a 5-point scale), most items showed a high level of satisfaction of 4.39 points or more. The smart bag program was evaluated to increase interest based on the time allotted and the students' level and to bolster their understanding of, and interest in, the fashion major. Therefore, this study is expected to be baseline to explore diversification of the fashion major work experience program, in order to create interest in the fashion major based on creative convergence competency.

This paper presents an implementation of a gesture recognition platform that can be used in a factory workplaces. The platform consists of signages that display worker's job orders and a control center that is used to manage work orders for factory workers. Each worker does not need to bring work order documents and can browse the assigned work orders on the signage at his/her workplace. The contents of signage can be controlled by worker's hand and arm gestures. Gestures are extracted from body movement tracked by 3D depth camera and converted to the commandsthat control displayed content of the signage. Using the control center, the factory manager can assign tasks to each worker, upload work order documents to the system, and see each worker's progress. The implementation has been applied experimentally to a machining factory workplace. This flatform provides convenience for factory workers when they are working at workplaces, improves security of techincal documents, but can also be used to build smart factories.

This paper aims at enlightening the properties, computational and implementation issues related to Kalman filter based state estimation algorithms and sliding mode observers, by applying them for estimating the states of a smart structure system. The Kalman based estimators considered in this work are Kalman filter and information filter and, the sliding mode observers considered are Utkin observer and higher order sliding mode observer. A fourth order linear time invariant model of a piezo actuated beam is used in this work. This structure is embedded with four number of piezo patches, of which two act as sensors, one as disturbance actuator and the other as control actuator. The performance of the state estimation algorithms is evaluated through simulation, for the first two vibrating modes of the piezo actuated structure, when the structure is maintained at first mode and second mode resonance.

Magneto-rheological fluids and magneto-strictive materials are of the well-known smart materials which are used to control and reduce the vibrations of the structures. Vibration analysis of a smart annular three-layered plate is provided in this work. MR fluids are used as the core's material type and the face sheets are made from MS materials and is assumed they are fully bonded to each other. The structure is rested on visco-Pasternak foundation and also is subjected to a transverse magnetic field. The governing motion equations are derived based on CPT and employing Hamilton's principle and are solved via GDQ as a numerical method for various boundary conditions. Effect of different parameters on the results are considered and discussed in detail. One of the salient features of this work is the consideration of MR fluids as the core, MS materials as the faces, and all of them under magnetic field. The outcomes of this study may be led to design and create smart structures such as sensors, actuators and also dampers.
