  • 본 논문에서는 N-스크린 환경에서 세션 이관 및 분리을 통해 사용자의 이종의 단말 간 유동적으로 컨테츠를 이동하고, 서비스 단말을 변경 할 수 세션 제어 구조와 방안을 제안한다. N-스크린 서비스에서는 사용자가 스크린 해상도, CPU 능력, 액세스망 인터페이스 등이 다른 복수의 단말을 사용할 수 있다. 또한, 사용자가 서비스 사용 중 단말을 변경하거나, 한 명의 사용자가 다중 스트림(One User Multi Stream)을 사용할 수 있어야 하므로, 이종의 다중 단말 간 컨텐츠를 이동시키거나 서비스 단말을 변경할 수 있는 등의 N-스크린 서비스를 위한 구조와 서비스 방안이 필요하다. 본 논문에서는, N-스크린 환경에서 세션 분리 및 이관 등을 제어할 수 있는 세션 관리 및 제어를 위한 노드들을 제안하고, 이 노드들과 사용자들 간의 인터랙션을 통해 이종의 다중 단말간 유동적인 컨텐츠 이동과 서비스 단말 변경이 가능한 N-스크린 환경에 적합한 세션 제어 구조를 제안한다. 제안된 방안은 단말 사양에 맞추어 세션 이관의 지연을 최소화하고 또한 서버의 부하를 최소화하도록 한다. 시뮬레이션의 결과를 통해, 제안하는 구조를 와 방안에 대한 효율성 및 성능을 분석하였다.

  • Since the guaranteed service quality(QoS) is spotlighted as a strategic competitive tool to Broadband Convergence Network(BcN) service providers, many scholars have dealt with QoS issues in the BcN environment. However, just a few researchers focus on end-users and most are lean toward service providers or technology itself. In this paper, therefore, we investigated how end-users could measure service quality in the BcN environment, and moreover, proposed the end-user oriented measurement guideline for BcN QoS. Through literature review and two surveys, four QoS dimensions and nineteen measurement items were derived from end-user's perspective. proposed QoS dimension and items would be utilized as meaningful tools for future BcN service.

  • Nigrospora is a monophyletic genus belonging to Apiosporaceae. Species in this genus are phytopathogenic, endophytic, and saprobic on different hosts. In this study, leaf specimens with disease symptoms were collected from host plants from the Shandong Peninsula, China. The fungal taxa associated with these leaf spots were studied using morphology and phylogeny based on ITS, TEF1, and TUB2 gene regions. In this article, we report on the genus Nigrospora with N. gorlenkoana, N. oryzae, N. osmanthi, N. rubi, and N. sphaerica identified with 13 novel host associations including crops with economic importance such as bamboo and Chinese rose.

  • Monitoring of soil fertility and crop productivity in long-term application of fertilizers is necessary to use fertilizers efficiently. This study was conducted to investigate effects of continuous application of lime for rice cultivation from 1969 to 2014. The treatments were no lime treatments (N, NPK, NPKC, and NPKS) and lime treatments (N+L, NPK+L, NPKC+L, and NPKS+L). The application of lime in addition to N, NPK, and NPKC tended to increase pH, exchangeable Ca, and available $SiO_2$. The input of mean annual $1,170Mg\;ha^{-1}yr^{-1}$ of lime increased pH $0.0042yr^{-1}$, $0.0062yr^{-1}$, $0.0127yr^{-1}$, and $0.0041yr^{-1}$ in lime treatments (N+L, NPK+L, NPKS+L, and NPKC+L) compared with no treatments (N, NPK, NPKS, and NPKC), respectively. The mean annual Ca field balance varied from 169 to $561kg\;ha^{-1}yr^{-1}$in no treatments, from 871 to $1,263kg\;ha^{-1}yr^{-1}$ in lime treatments, indicating that Ca was accumulated in the soils. The mean annual Ca field balance in silicate fertilizer treatments (NPKS, NPKS+L) were higher than that of other treatments because silicate fertilizer included Ca component. Grain yield of rice had no significant differences between no lime treatments and lime treatments. Thus the application of lime led to changes in soil chemical properties but had no impact on the production of rice.

  • We consider a supply chain consisting of a make-to-order manufacturer and N component suppliers and study the impacts of the number of suppliers on component inventory management. The manufacturer has full information and continuously observes the state of both component inventory level and customer backorders. Based on this information, the manufacturer determines whether or not to place a component purchasing order to a supplier among N suppliers even though some orders are in process by other suppliers. The goal of this paper is to numerically identify the manufacturer's purchasing policy which minimizes the total supply chain cost and the best choice of N. Our model contributes to the current literature in that the problem of simultaneously considering multiple outstanding orders and incorporating order setup cost into the model has not been covered yet. From numerical experiment, we investigate how much the policy with N suppliers can contribute to reducing the supply cost compared to the policy with a single supplier.

  • This paper describes a new species of chigger mite (Acari: Trombiculidae), Gahrliepia cangshanensis n. sp., from rodents in southwest China. The specimens were collected from Yunnan red-backed voles, Eothenomys miletus (Thomas, 1914), and a Chinese white-bellied rat, Niviventer confucianus (Milne-Edwards, 1871) in Yunnan Province. The new species is unique mainly in its number of dorsal setae (n=21), and it has the following features: fT (formula of palpotarsus)=4B (B=branched), fp (formula of palpal seta)=B/N/N/N/B (N=naked), a broad tongue-shaped scutum with an almost straight posterior margin, and 17 PPLs (posterior posterolateral seta) with a length of 36-43 ${\mu}m$. This chigger mite may also infect other rodent hosts and may be distributed in other localities.
