김정혜,박종면,오훈일,Kim, Jung-Hye,Park, Jong-Myeon,Oh, Hoon-Il 고려인삼학회 1994 Journal of Ginseng Research Vol.18 No.3

A study was designed to investigate the sorption characteristics of binary mixture of red ginseng powder and maltodextrin(DE-17) or lactose stored at various relative humidities ranging from 52% to 93%. At low relative humilities below RH 67%, the sorption equilibrium was easily achieved, whereas at higher relative humidity values over 75%, all of the mixtures tended to absorb moisture continuously with an increase in storage time. A linear equation of log(dw/dt): a log(t)+ log b was found to be valid between the sorption rate and storage time with respect to storage humilities. A linearity was also found between log(1-Aw) and the amount of water absorbed over the Aw range of 0.52∼0.93 and the slope was affected by the kind of sugar added with that of red ginseng powder and maltodextrin mixture being the smallest.

무선 멀티미디어 센서 네트워크(Wireless Multimedia Sensor Network : WMSN)는 기존 스칼라 데이터 뿐만 아니라 음성, 이미지, 동영상 등 다양한 멀티미디어 정보를 전달해야 하므로 다양한 특성을 가진 트래픽을 효율적으로 처리하기 위한 서비스 품질(Quality of Service : QoS)를 지원할 수 있는 메커니즘이 필요하다. 본 논문은 WMSN 에서의 트래픽 유형을 주기적 모니터링 트래픽, 이벤트 트래픽, 멀티미디어 트래픽, 쿼리 기반 트래픽으로 분류하고, 각 트래픽 유형에 따라 지연, 에너지 효율성 및 신뢰성에 대해 차별화된 QoS를 제공할 수 있는 마킹 알고리즘과 큐 관리 메커니즘을 제안한고, 시뮬레이션을 통해 성능을 분석한다. Since Wireless Multimedia Sensor Network(WMSN) needs to process various multimedia data such as audio, image and video data as well as scalar data, it requires a mechanism that can support Quality of Service(QoS) to handle efficiently. This paper classifies traffic in WMSN as periodic monitoring traffic, event traffic, multimedia traffic and query-based traffic, proposes marking algorithm and queue management mechanism that guarantee differentiated QoS in terms of delay, energy efficiency and credibility on each traffic and conduct performance analysis with simulation.

무선 센서 네트워크는 다수의 센서 노드로 구성되며, 센서 노드들의 협력 작업을 통해 하나의 공통 작업을 수행한다. WSN 의 트래픽은 주기적인 모니터링 트래픽, 이벤트 발생 트래픽 및 쿼리 기반 트래픽으로 분류된다. 주기적인 트래픽은 발생 빈도는 낮지만, 다수의 센서노드들이 일정한 간격으로 트래픽을 생성하기 때문에 전체 트래픽 관점에서 볼 때 많은 비중을 차지하고 있다. 본 논문에서는 이러한 주기적 트래픽에 대해 에너지 효율적으로 처리하는 네트워크 프로토콜의 트래픽 제어 알고리즘을 제안하고, 이에 대한 성능 분석을 수행한다. Wireless sensor network is consist of multiple sensor nodes and performs a shared tasks through the coordination of sensor nodes. Traffic in WSN is categorized as periodical monitoring traffic, event-driven traffic and query-based traffic. Periodic traffic takes significant proportion of the whole traffic processing because multiple sensor nodes generate traffic in a steady interval although the generation frequency of periodic traffic is low. In this paper, we propose a traffic control algorithm of network protocol for periodic traffic in terms of energy efficiency and conduct performance analysis of the algorithm.

日本語学習において作文は4つの機能の中で一番最後になされる総合学習である。作文は、確実な意思伝達の機能や、遠くにいる人に意思を伝える機能、長期間保存することの出来る機能などがあり、大変重要なものである。 初級日本語学習者の書いた作文の誤用を分析した結果、韓国語を母語とする初級日本語学習者は、語順の類似している韓国語の言語体系から影響を受けていることが判明した。これらの誤用をなくす方案として、基礎段階において、多くの日本語を体得することが重要であることを提示する。少なくとも基礎日本語においては、｢日本語講読｣との連携で楽しい歌、詩、小説、シナリオなどやさしい日本語で書かれている、学習者の興味をそそる内容のものを多く学習することが効果的であると考える。また、韓国語の言語体系の影響とは関係ないと思われるイ形容詞の過去形や可能動詞·受け身動詞などは、それらが使用されている楽しい会話文で習得できるのではないかと考える。そして、これら基礎段階で習得した日本語を使って作文をし、作文での誤用例を文法の授業に活用するという方法が効率的な日本語学習方法であると考える。 しかし、何と言っても日本語で正しく作文するには、たくさん読んで、たくさん書いて、それらの全てを添削して、誤用について説明するということ以外に王道はないと考える。
