ICT기술이 전 산업으로 퍼져가며 모든 산업이 변화하고 있다. 4차 산업혁명 바람이 불고 있는 것이다. 농업 역시 예외일 수는 없다. 특히나 일손 부족으로 허덕이는 농가에 ICT기술은 반가운 소식이다. 정부에서도 두 손 걷어붙이고 나서고 있다. KT, SK텔레콤 등과 시범사업에 착수한 것이다. 센서와 네트워크 기반의 스마트 농업생산 시스템 '스마트 팜(smart farm)'은 이제 미래가 아닌 현실이 되고 있다. 이러한 흐름에 맞춰 농산물 포장 역시 변화하고 있다. LG가 세운 농축산 창업 특성화대학 연암대학교에서 스마트 팜을 위한 포장디자인 프로젝트를 진행 중인 김곡미 교수를 만나 스마트 팜은 무엇이고, 스마트 팜을 위한 포장디자인의 필요성, 차별화 전략 등에 대한 이야기를 들어보았다.

EJB는 Sun사에서 발표한 분산 객체 구조에 맞는 서버쪽 컴포넌트 아키텍쳐이다. EJB를 사용하면 다중 네트워크 환경에서 애플리케이tus의 디자인과 개발, 배포가 쉬워진다. 개발자는 하부 사항에 대해 신경쓰지 않고 상위 레벨에서 애플리케이션을 설계할 수 있다. EJB 1.1 명세서는 그러한 내용을 나타내고 있는 명세서이다. 하지만 이 명세에서는 멀티 스레드를 허용하지 않는다. 멀티 스레드는 프로그래밍에서 상당히 유용한 것으로 멀티 스레드를 사용하면 다른 오브젝트에 영향을 주지 않으면서 작업을 수행할 수 있는 등 여러 가지 이점이 많다. 본 논문에서는 이러한 이점을 살려서 명세서에 따르면서 멀티 스레드를 생성하는 방법에 대해 알아보고자 한다. 본 논문에서 제시하는 방법은 3가지이고 각각 장단점이 따른다 .

Recently, when software architecture is designed, the efficiency of reusability is emphasized. The reusability of the design can raise the quality of GIS software, and reduce the cost of maintenance. Because the object oriented GoF design pattern provides the class hierarchy that can represent repetitively, the importance is emphasized more. This method that designs the GIS software can be applied from various application systems. A multiple distributed sensor network system is composed of the complex structure that each node of the sensor network nodes has different functions and sensor nodes and server are designed by the combination of many classes. Furthermore, this sensor network system may be changed into more complex systems according to a particular purpose of software designer. This paper will design the CATL model by applying Facade pattern that can enhance the efficiency of reuse according to attributes and behaviors in classes in order to implement the complicated structure of the multiple distributed sensor network system based on TinyOS. Therefore, our object oriented GIS design pattern model will be expected to utilize efficiently for design, update, or maintenance, etc. of new systems by packing up attributes and behaviors of classes at complex sensor network systems.

The rapid proliferation of in-home and office information applications and services is driving the need for new wireless technologies enabling wideband short range multimedia communications. Due to the growing demand for higher quality media and faster wireless connections, several IEEE standardization groups are considering very high data rate alternatives physical layer(s) for Wireless Personal Area Network (WPAN). The Ultra Wide Band (UWB) multiple access technology based on very narrow pulse transmission, is one viable candidate for these applications providing very high bit rates services, low power consumption and accurate positioning capability. In this paper we provide a methodology to evaluate the UWB system BER performance in UWB wireless fading networks with power controlled UWB devices are considered. Results can be used to analyze the performance of a given network topology and to provide useful design ideas for an UWB home sensor network.

This paper focused on fading out the factors of design innovation. Based on the previous studies, several factors were extracted to be tested by Delphi method among 15 experts in the design area. Delphi test showed a convergent result after the second round of questioning. Design mind of managers was conceived as the most important factor among those tested. On the base of importance, capability of design company was the second and industrial design demand was the third. Even though design manpower, design infrastructure and innovation network were ranked below the 4th factors, the absolute differences between high ranked factors and low ranked ones were not much wide. So. relatively low ranked factors were not negligible at all to get a desirable success in design innovation. This study provides some insights for the success of design innovation. First of all, design innovation could be achieved only when factors tested on this study upgraded simultaneously together. Desirable effect could not expected by a simple support such as logo design or kind of simple measure.

The purpose of study was to analyze the trends of 2005 to 2018 revised 'convergence technology research' through text network analysis using NetMiner4.0 program. Data analysis was conducted by using keyword analysis, centrality analysis of 653 authors' keyword from 177 journals. The results of the study are as follows. First, Research on Converging Technology has been studied steadily over the past 13 years in Department of Industry Convergence. Second, the results of the search term frequency analysis show that the 'convergence technology', 'technology convergence', 'convergence', 'design', 'convergence education', 'STEAM', 'convergence research' were used as the main keywords of convergence technology research. Third, Community analysis results show that five communities have been classified five categories according to the characteristics of the search terms 'only IT', 'Cultural industry utilizing Convergence contents', 'Technology innovation and research analysis' And patent development'. Based on these results, we proposed the future directions of convergence technology research.

The security of wireless sensor networks is a challenging research area where the resources constraints are a bottleneck for any successful security design. Due to their computational feasibility, symmetric key algorithms that require key pre-distribution are more desirable for use in these networks. In the pre-distribution scheme, keys or keying materials are assigned to each node prior deployment to guarantee a secure communication within the entire network. Though several works are introduced on this issue, yet the connectivity and resiliency are imperfectly handled. In this paper, we revisit the grid based key pre-distribution scheme aiming to improve the connectivity, introduce a higher resiliency level, simplify the logic of key establishment and maintain same level of used of resources usage. The core of our modification relies on introducing the novel plat-based polynomial assignment and key establishment mechanism. To demonstrate the advantageous properties of our scheme over the revisited one, details of consumed resources, resulting connectivity, security and comparisons with relevant works are introduced.

Conventional design producing systems using the Internet are largely classified into two groups: a basic type in which an operator of a design producing site receives an order for manufacture of a design from a purchaser, produces the design based on the content of the received order, and delivers the produced design to the purchaser; and a type in which a purchaser inspects given designs and select one of them for purchasing. Such conventional design producing systems have following problems. Firstly, receiving an order over the internet and delivering a produced design to a purchaser has nearly the same procedure as a conventional logo design procedure with the sole exception that an order can be received through the Internet. Therefore, the production of a design still costs a great deal and takes much time. Secondly, inspecting given designs, selecting one and producing the selected design is like simply selecting a picture, and thus a purchaser is not allowed to modify a design. To solve the above problems, it is an object of the present a new solution to provide a self-design producing system and method using network, in which a purchaser searches a design database for a design suitable for the purchaser's company, determines a design database by modifying design conditions, and makes an order for manufacture of a product to which the determined design is applied, through the Internet.

침입 탐지 시스템은 네트워크나 호스트에 대한 오용, 남용, 또는 허가되지 않은 접근을 탐지하는 기능을 갖는 시스템이다. 최근 침입들은 그 종류가 매우 다양화되고, 탐지하기가 매우 어려운 형태로 나타나고 있다. 이러한 침입으로 대표적인 것이 분산 공격과 스텔시 공격(Stealthy Attack)이 있다. 분산 공격은 침입자가 공간적으로 분산되어 이를 탐지하기 어렵게 하는 공격을 말하며, 스텔시 공격은 시간적으로 분산되어 이를 탐지하기 어려운 경우를 말한다. 침입 탐지 시스템의 모델링 및 시뮬레이션을 위해서는 침입 탐지 시스템 모델에 필요한 침입을 제공하고, 침입에 대한 탐지 능력을 평가하기 위한 experimental frame을 디자인 해야한다. 본 연구에서는 분산 공격과 스텔시 공격 기능을 갖는 침입 생성 모델링 방법을 소개하며, 침입 생성을 위해 요구되는 침입 정보 베이스의 역할 및 저장 정보를 소개한다. 또한, 침입에 대한 탐지 능력 평가를 위한 Transducer 모델의 디자인을 소개한다.
