李敏錫,朴東宣 전북대학교 공업기술연구소 1995 工學硏究 Vol.26 No.-

IPC(Inter-processor communication) plays an important role in a distributed ATM(asynchronous Transfer Mode) switching system. A reasonable approach to build a high-speed network for IPC is to use links of a ATM swich itself. But it is bon an economical startegy that an expensive ATM switch link is porvided for each processor. Therefroe we porpose an dfficient architceture of a high-speed link among several processors for the economical use of ATM switch link among several processors for the economical use of ATM swich links. In this paper, we also analyze the simulation resluts to evaluate the performance of the proposed architectrue. The p개posed HCCD distributes cells from a switch link to local processors, or concentrates cells from local processors to a swich link. This design is to guarantee a high throughput for the IPC(inter-processor communication) link in a distributed ATM switching system. The HCCD is designed in a modular architecture to provide the extensibility and the flexibility. The main characteristics of the HCCD include 1) a self-testing function for detecting system faults, 2) a self-routing among local processors, 3) a cell-based statistical multiplexing/demultiplexing function,4) a multicasting capablity, and5) a function for updating the VPI table.

1886년 博文局의 『萬國政表』 출간과 세계지리 정보의 유통

李旼錫(Lee, Min seok) 한국사연구회 2014 한국사연구 Vol.- No.166

With the purpose of the Joseon Dynasty's understanding the West in 1880s, this research compares and analyzes Mangukch?ngp'yo which was published by Bakmunguk in 1886 and Yeojaechalyo in terms of the former's background, original text and influence. Joseon Dynasty's signing Chosun-the U.S. Firendship and Commerce Treaty in 1882 is followed by other successive treaties with the West such as the U.K. and Germany in 1880s, which led to joining into the Modern Treaty System. Therefore, it became necessary for Joseon Dynasty to break Haebangnon, which means National Security, and understand the West more concretely. In order to meet the needs of the times, Joseon Dynasty tried to absorb the Western newest information while making Bakmunguk translage and publish The Statesman's Year-Book in 1886, which was originally published in the U.K.. Mangukch?ngp'yo included general information about politics, economy, society and culture of 49 countries including Joseon Dynasty and Qing(China), which helped Joseon's society accept the West. As the latest Western Perception book in 1880s, Mangukch?ngp'yo influenced the publication of Yeojaechalyo, the private geography book written by Oh Hoeng-mook. In 1896, furthermore, it resulted in the publication of geography textbook which was issued by Hakbu. This research has significance for indicating the fact that Joseon Dynasty made effort into publication in order to understand the West in 1880s. Besides, it is meaningful that this research confirms the fact that the original text of Mangukch?ngp'yo is The Statesman's Year-Book, which the earlier studies have failed. Moreover, it has a value of discovering that the influence of Mangukch?ngp'yo was exerted on not only the publication of Yeojaechalyo but also geography textbook of Hakbu in the period of the Gabo Reform of 1894.

Progress in topographically defined scaffolds for drug delivery system

이민석,김성민,이동현,전진,양희석 한국약제학회 2018 Journal of Pharmaceutical Investigation Vol.48 No.2

The conventional drug delivery systems including oral and transdermal delivery have limitations. Oral route of drug delivery shows poor drug stability, solubility in physiological barrier of digestive tract. Also it is caused tissue damage and pain for ingesting of various dosage forms. Also, transdermal drug delivery is limited permeability of therapeutic agents by skin barrier. To overcome revealed limitations in conventional drug delivery systems, many researches have been investigated to design drug delivery methods with topographical features of micro- and nanoscale which lead to enhance cellular adhesion, drug permeation, regulate releasement of therapeutic agents and incorporate functionalization of smart polymers as delivery platforms for target tissues. Recently, advances in micro- and nanotechnology have been progressed in drug delivery systems that facilitate etching highly ordered structures with biodegradable and biocompatible polymers and combining topographical features with proper strategies which are applied according to the characteristics of target tissues. In this review article, we introduce highlights of conventional and recent fabrication techniques about topographical features for drug delivery and outline recent therapeutic applications with topographically defined devices.

간척의 역사적 의미와 간척문화유산의보존·활용 방안 연구 - 새만금 지역 근·현대 간척 시설을 중심으로 -

Reclamation is the act of creating new lands by constructing dikes in offshore tidal flats to utilize them forvarious purposes, including the establishment of farmland to secure food for an increasing population. Based on thefact that reclamation has resulted in drastic changes in the environmental, economic, social, and cultural aspects ofland expansion and development, population movement, and the formation of cities since ancient times, I reviewedthe value of reclamation sites and addressed the issue of how to preserve and utilize them. “Reclamation culture” refers collectively to the recognition and concept system, behavior styles, and culturalproducts created by changes in the environment, and the tangible, intangible, and natural heritage generated directlyand indirectly by reclamation is defined as “reclamation cultural heritage”. It shows that the historical background ofreclamation accords with prevailing trends, and that the reclamation sites possess cultural heritage value due to theirhistorical, academic, and scarce characteristics. Numerous reclamation cultural heritage sites at the Gwangwhal and Gyehwa dikes are on the verge of beingdestroyed, with their original function having ended after the construction of Saemangeum Sea Wall. I proposemeasures to preserve these under the principle that utilization is based on the basic premise of conservation. First ofall, modern and contemporary reclamation sites must necessarily be designated and managed as registered culturalproperties, local cultural heritage, future heritage, and agricultural heritage. In particular, as it has been confirmedthat reclamation sites created after the Goryeo and Joseon dynasties and the 1950s have not been designated ascultural heritage sites. It is necessary to review the characteristics and values of such reclamation sites through a fullsurvey of national reclamation data. Effective and sustainable utilization of reclamation cultural heritage, which has not been acknowledged in thepast due to its close relationship with our lives, is necessary to search for hidden stories found within that heritage, toorganize governance for the efficient use of reclamation resources, and to build a museum to collect and display thehistory and culture of the reclaimed areas. Finally, through links with countries with experience in reclamation, wewill be able to cope jointly with international issues such as those pertaining to society, culture, and environment, andwould be able to implement various projects to further the advancement of human beings. 간척은 인구 증가에 따른 식량 확보를 위한 경작지 등 다양한 용도로 활용하기 위하여 근해의 간석지에 제방을 축조하여 새롭게 토지를 창출하는 행위이다. 고대부터 간척으로 인하여 토지의 확대 및 개발, 인구의 이동, 도시의 형성이라는 환경적, 경제적, 사회적, 문화적인 측면에서 급격한 변화가 초래되었다는 사실에 기반하여 간척 시설물의 가치를 검토하고 보존 및 활용 방안을 다루었다. 간척 문화는 간척에 따른 제반 환경의 변화에서 생성된 사람들의 인식과 관념 체계, 행위 양식, 문화적 생성물을 총칭하며, 간척에 의해 직·간접적으로 생성된 유형 유산과 무형 유산, 그리고 자연 유산을 간척문화유산으로 정의하였다. 간척을 추진했던 역사적 배경이 시간의 추이에 따라 다르며, 간척 시설물은 역사성, 학술성, 희소성이 있기 때문에 문화유산으로서의 가치가 있음을 확인하였다. 새만금 방조제 건설 이후 그 본래의 기능을 마감한 광활, 계화 방조제를 중심으로 수많은 간척문화유산이 멸실 위기에 놓여 있다. 활용은 보존을 기본 전제로 한다는 생각 아래 제도적 측면에서의 보존 방안을 제시하였다. 먼저 근현대 간척 시설물에 대해 등록문화재, 향토문화유산, 미래유산, 농업유산으로 지정하여 관리할 필요가 있다. 특히 고려~조선시대 및 1950년대 이후에 조성된 간척 시설물이 문화재로 지정되지 않은 것으로 확인되어, 이 시기를 비롯하여 전국 간척자료에 대한 전수 조사를 통해 간척 시설물의 특징과 가치에 대한 검토가 요구된다. 우리 삶과 밀착되어 그간 주목받지 못했던 간척문화유산의 효율적이고 지속 가능한 활용 방안으로는 그 유산에 내재된 스토리 발굴, 간척 자원의 효율적인 활용을 위한 거버넌스의 구성, 해당 간척 지역의 역사와 문화를 수집하고 전시하는 박물관 건립이 필요하다. 마지막으로 간척사업의 경험이 있는 국가들과의 연계를 통해 간척에 따른 사회, 문화, 환경 등 국제적 이슈에 대해 공동으로 대처하고 인류 발전을 위한 다양한 사업을 실행할 수 있을 것이다.
