$Ni_3[Co(CN)_6]_2$ PBAs의 하소과정을 통해 단분산된 $NiO/NiCo_2O_4$ 나노큐브를 성공적으로 합성했다. 단분산된 $Ni_3[Co(CN)_6]_2$ PBAs 나노큐브는 수열합성 반응 시 생성된 핵 들의 '자기조립'에 의해 형성된다. 이때 입자의 자기조립 속도는 온도와 계면활성제인 SDBS(Sodiumdodecylbenzenesulfonate)의 양에 의해 영향을 받으며, FESEM 분석을 통하여 SDBS: 0.25 g, 온도: $60^{\circ}C$에서 단분산된 200 nm의 PBA 나노큐브들을 얻을 수 있었다. 최적의 하소 조건을 결정하기 위해 Thermogravimetric-Differential Thermal Analysis(TG-DTA)를 통해 열적 거동을 확인하였다. 그리고 PBA 전구체 및 $NiO/NiCo_2O_4$ 입자의 형상과 결정성을 확인하기 위해 Field emission scanning electron microscopy(FESEM)과 X-ray diffraction(XRD) 분석을 진행하였다. $NiO/NiCo_2O_4$ nanocubes were successfully synthesized via the calcination process of $Ni_3[Co(CN)_6]_2$ PBAs. The prepared monodispersed $Ni_3[Co(CN)_6]_2$ PBAs were aggregated by 'self-assembly' of the nuclei generated during the synthesis reaction. The self-assembly rate of the particles is affected by the temperature and the amount of surfactant SDBS (sodium dodecylbenzenesulfonate). FESEM analysis shows that monodispersed 200 nm PBA nanocubes are obtained at 0.25 g SDBS and $60^{\circ}C$ temperature. Thermal behavior was confirmed by thermogravimetric-differential thermal analysis (TG-DTA) to determine optimal calcination conditions. Then, field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analyzes were performed to investigate the morphology and crystallinity of the particles precursors and $NiO/NiCo_2O_4$ nanocubes.

LonWorks/IP 서버를 이용한 Web 기반 환경 모니터링 시스템에 관한 연구
곽성훈,최기상,최기홍,강상혁 제어로봇시스템학회 2008 제어로봇시스템학회 국내학술대회 논문집 Vol.2008 No.10
Recently, demand for environmental monitoring system for public places such as schools, subway stations, etc. is increasing. Also, remote monitoring as well as local monitoring is becoming more and more important. However, the device control networks that can be used for monitoring purposes basically work locally, and lack the capability of easy user connection. Here comes the need for smart integration of device control network with data network. In this study a structure of virtual device network that comprises both the LonWorks device network and the IP data network is proposed for environmental monitoring purposes. Then, a Web-based environmental monitoring system based on the virtual device network is designed and realized.

The Chong tong gun and cavalry had big role of military organization in theearly days of Joseon Dinasty. The main arms in past military system were cavalriesand tanks, but after development of gunpoeder weapons, they tried to accommodatenew weapon in their military organization. In the background of the change of militaryorganization in the early days of Joseon Dinasty, there were various factors suchas reuction of cavalries caused by some economic factors, inventrion of new weapnsdue to the developmetn of science technology and invasion of the border area. The ancient East Asian military theory emphasized the harmonious operationof extraordinary tactics(奇兵) and standard tactics(正兵). The military theory ofJoseon accepted the ancient theory, so the cavalry played a role of extraordinarytactics(奇兵) and the gunpowder weapon was given a role to the standard tactics(正兵). The military theory of the early days of Joseon dynasty was developed fromthe existing theory thereby technology developing. 조선 전기 군사편제에서 큰 역할을 차지하는 무기는 총통과 기병이었다. 과거의군사편제에서 핵심이 되는 병종은 기병과 전차였으나, 화약무기가 개발된 이후 새로운 무기를 기존의 군사편제에 수용하려는 시도가 이어졌다. 조선 전기 군사편제 변화의 배경에는 여러 경제적 요인으로 인한 기병의 감소와 과학 기술의 발전으로 인한 새로운 무기의 개발, 국경 지역의 침입과 같은 복합적인 요인이 있었다. 고대 동아시아의 군사이론은 奇兵과 正兵의 조화로운 운용을 강조했다. 조선의 군사이론은고대의 이론을 수용하여 기병은 奇兵으로의 역할을 수행했고, 화약무기는 정병으로의 역할을 부여했다. 조선 전기의 군사이론은 기술의 발전에 따라 기존의 이론을 발전시키며 변화했다.

In recent years, several studies have attempted to develop and discover convergence between information technology and biotechnology. Currently, researchers are dedicatedly studied the rehabilitation of medical equipment’s through the emerging trend, convergence technology. This paper presents the design and implementation of robotic exoskeleton to facilitate the rehabilitation of elbow and shoulder movements. The proposed robotic exoskeleton will have a capability to be controlled using mobile device. This capability can provide user friendly controlling mechanism which is convenient for the patients. The design and implementation stages will follow the TDD(Test-Driven Development) software development process that combines test-first development and refactoring tasks. The iterative testing and refactoring activities in TDD provide highly verified code that would increase the reliability and stability and reduce the development time.

Examined in this article are certain changes that occurred in terms of military strategies in the early days of Joseon. Understanding of them would most definitely prove useful in the task of analyzing how the early Joseon military institution was actually formalized. In order to determine what kind of discussions concerning military operations and theoretical suggestions prompted such changes in military strategies, the text called 『O’wi Jinbeob(五衛陣法)』 is examined here in an effort to clarify the ultimate direction that would have been taken in early Joseon strategies. The Joseon government was very much interested in establishing its own military institution. And one of the areas the government particularly concentrated its efforts on was the publication of military strategic manuals (“Jinbeob-so, 陣法書”). Jeong Do-jeon(鄭道傳)’s manual 『Jinbeob(陣法)』, which is the oldest strategy manual that remains today, contained basic theories of military operations as well as contents lifted from ancient Chinese strategy manuals. Unfortunately, much of them essentially had nothing to do with the Joseon reality at the time. Added to that, overall information collected in the manual was too brief and ambiguous to be used in training soldiers, or to be effectively consulted by personnel in charge of such operations. A leap from the 『JIndo-beob(陣圖法)』 stage to the 『Jinbeob(陣法)』 stage was led by King Sejong and an official named Byeon Gye-ryang(卞季良). The contents of the former text reflected the contents of the latter one, and at the same time was only composed of elements that were absolutely necessary in military training operations. Another manual called 『Gyechuk Jinseol(癸丑陣說)』 was a military strategy manual that was compiled and published in 1433(15th year of Sejong’s reign), when the so-called Pa’jeo-gang(婆猪江) river campaign was launched. This manual is hailed as the one that is full of real wartime examples that could inspire trainers and trainees. It is possible that the Pa’jeo-gang campaign may have had something to do with the compilation of this manual, but the actual publication date as well as people involved in the compilation process, suggest otherwise. The aforementioned 『O’wi Jinbeob』 was compiled and published in 1451, the first year of king Munjong’s reign. Compared to earlier manuals, manners of troop organization and fashion of the command structure were considerably revised, in order for the readers to become capable of facilitating efficient mobilization of much larger armies. Usage of military assets were also described in great detail, with a standardized weapon usage protocol dictated as well, as developments in weapon production and creation of gunpowder-based firearms were requiring such upgrades to be made in the manuals. All of these were made possible because the compilers took time to analyze previous military theories and adjust them in the new book accordingly, while also taking advantage of past experiences collected from many previous operations including the Pa’jeo-gang campaign. The Joseon military strategy, which in the early days of the dynasty was rather based upon theoretical and philosophical elements, later continued to shift its focus upon techniques that could be used in actual fighting and also planning of launchable campaigns. The military strategy was continuously refined so that it could be applied in operations that would involve much bigger military units, and it kept incorporating ancient military techniques that could be adjusted to benefit army units placed in contemporary situations.
