Recently, intelligent packaging of foods has been increasingly developed in response to the growing interest of consumers in checking food quality. Indicators, an important element in intelligent packaging, change color to detect specific substances or indicate food quality changes. Gas indicators can be built into food packaging to detect volatile substances that are released when food quality changes. Ethylene gas is produced as climacteric fruits ripen. Climacteric fruit ripening results from a rapid increase in ethylene production and respiration. In the case of packaged fruits, the ethylene gas concentration in the headspace is closely related to the ripeness of each fruit variety. If an ethylene gas indicator that can be used in fruit packaging is available, the consumer will be able to eat the fruit at the optimal time. In this paper, the characteristics and pros and cons of the ethylene gas indicators developed so far were analyzed by reviewing various types of indicators such as metal reduction-based indicator, fluorescence-based indicator, pH indicator-based indicator, and liposome-based indicator.

A short shot is an incomplete molded part caused by insufficient material injection into the mold. Remedial actions to control the process conditions can be taken by injection molding experts based on their knowledge and experiences. However, it is very difficult for non-experts to avoid short shot by finding the proper process conditions such as mold temperature, melt temperature and filling time. In this paper, an intelligent generator of optimal process conditions based upon fully logic algorithm is proposed so that trial and error can be minimized and non-experts an well at experts can also find the optimal process conditions.

When a semiconductor package is assembled, various materials such as die attach adhesive, lead frame, EMC (Epoxy Molding Compound), and gold wire are used. For better preconditioning performance, the combination between the packaging materials by studying the compatibility of their properties as well as superior packaging material selection is important. But it is not an easy task to find proper packaging material sets, since a variety of factors like package design, substrate design, substrate size, substrate treatment, die size, die thickness, die passivation, and customer requirements should be considered. This research applies case-based reasoning(CBR) technique to solve this problem, utilizing prior cases that have been experienced. Our particular interests lie in building decision support model to aid the selection of proper die attach adhesive. The preliminary results show that this approach is promising.

This study proposes a plan to construct an integrated platform that reduces manufacturing costs and efficiently produce by integrating the systems of main producers, production subcontractors, and raw material subcontractors for the production of food packaging containers. The production plan of food packaging containers and raw materials is established in real time between the main producers, production subcontractors, and raw material subcontractors in consideration of the demand characteristics of each product. It establishes basic information that all processes from the production planning stage to the forwarding stage of the product are linked to each other. The progress of each producer of interlinked processes is shared in real-time to improve productivity and quality of food packaging containers and raw materials and reduce manufacturing costs. By monitoring the system of the main producer and the production subcontractor in real time, the production of food packaging containers is performed in a timely manner, thereby improving productivity. The application of the plan-do-check-action (PDCA) process, which includes planning, execution, evaluation and improvement in the production operation processes of the main producer, production subcontractor and raw material subcontractor, enables improved production compliance rate. The contents of the main producers, production subcontractors, and raw material subcontractors are managed in real time, then a converged production management system is established through the platform proposed in this study to ensure timely supply and demand of raw materials without delay in ordering.

In this paper, a MEMS tunable capacitor was successfully designed and fabricated using an aluminum nitride film and a gold suspended membrane with two air gap structure for commercial RF applications. Unlike conventional two-parallel-plate tunable capacitors, the proposed tunable capacitor consists of one air suspended top electrode and two fixed bottom electrodes. One fixed and the top movable electrodes form a variable capacitor, while the other one provides necessary electrostatic actuation. The fabricated tunable capacitor exhibited a capacitance tuning range of 375% at 2 GHz, exceeding the theoretical limit of conventional two-parallel-plate tunable capacitors. In case of the contact state, the maximal quality factor was approximately 25 at 1.5 GHz. The developed fabrication process is also compatible with the existing standard IC (integrated circuit) technology, which makes it suitable for on chip intelligent transceivers and radios.

Packaging protects products and delivers information to consumers, and interacts with consumers using various technologies such as NFC and QR Code. Recently, augmented reality technology is widely used in the marketing field, and augmented reality market is expected to continue to grow according to Gartner Hype cycle. However, augmented reality is only used by a few companies in the packaging field. By applying augmented reality to packaging, companies can move away from the limited packaging size and provide consumers with more information about their products. In addition, augmented reality can improve the understanding of the product to consumers by interacting with consumers through a variety of content, and positively attract consumers' interest in the brand. Therefore, this study summarized the definition, characteristics, advantages, and market status of packaging and augmented reality, and analyzed the characteristics and cases of content types of augmented reality. As a result, we confirmed the characteristics of marketing using augmented reality, and especially the necessity of applying augmented reality as a marketing tool in the field of packaging.

The introduction of industrial intelligent robot using vision sensor has been interested in automated factory. 2D and 3D vision sensors have used to recognize object and to estimate object pose, which is for packaging parts onto a complete whole. But it is not trivial task due to illumination and various types of objects. Object image has distorted due to illumination that has caused low reliability in recognition. In this paper, recognition method of complex shape object has been proposed. An accurate object region has detected from combined binary image, which has achieved using DoG filter and local adaptive binarization. The object has recognized using neural network, which is trained with sub-divided object class according to object type and rotation angle. Predefined shape model of object and maximal slope have used to estimate the pose of object. The performance has evaluated on ETRI database and recognition rate of 96% has obtained.

물류 표준화의 핵심은 수송, 보관, 포장, 상/하역, 정보/보안의 물류활동간의 호환성과 연계성의 확보이다. 국제표준 채택을 의무화하고 있는 WTO/TBT 협정을 차치하더라도 물류표준화의 정도는 국가의 물류경쟁력을 결정짓는 가장 중요한 척도라고 할 수 있다. 특히 한 중 일 3국의 경우 교역랑만 5조 3,236억불로 전 세계 교역량의 17.6%(2010년 기준), GDP 합계 12조3443억 달러로(2010년 기준) 세계전체 GDP 62조 9093억 달러 중 19.6%, 해운물동량은 전 세계 물동량의 60% 이상을 차지하고 있는 상황에서 물류경쟁력은 곧 국가경쟁력으로 보아도 무방하다. 아직도 국내에서는 물류분야 간 연계와 첨단정보기술이 결합된 현장중심의 융 복합 표준이 미비하고 대부분의 경우 해외국가들이 자신들의 입장대로 추진하거나 선점한 표준을 따라가기 바쁜 실정이었다. 스마트물류표준화는 이러한 현실에서 탈피하여 글로벌 물류표준을 선도하고 국내 현실에 적합한 현장물류표준을 반영하자는 취지에서 출발한다. 스마트물류는 i-ULS(Intelligent-Unified Logistics System) 체계, 즉 IT와 각 물류기술을 융합하여 표준화시키는 것은 물론 기존 표준을 산업현실에 맞게 반영해 나가는 것이 국가표준코디네이터로서의 주요한 목표가 되고 있다. 본 고는 전년도 스마트물류 표준화로드업에 작성된 표준화기술 중 산업체 설문을 통하여 10대 주요 표준화 트렌드를 선정하여 정리한 것이다. 10대 표준화 기술로는 순환물류포장시스템, 실시간 위치추적기술, 스마트컨테이너(Smart Freight Containers), 해상용 컨테이너 모니터링 시스템(CTMS), 글로벌 포장 표준모듈, 친환경물류 표준지표, 스마트물류 포장용기, 스마트그린물류센터(Passive Warehouse), 모바일 RFID 물류 적용 기술, Modal Shift(전환교통) 등이 선정되었다. 이번 4월호 특집에서는 10대 표준화 전략트렌드 가운데, 스마트물류에 대해 알아보도록 한다.
